Raw Blame History

Changes with Apache 2.0.17-dev
*) Make ab work again by changing its native types to apr types and formats.
[Justin Erenkrantz <jerenkrantz@ebuilt.com>]
*) Move the byterange filter and all of the supporting functions back
to the HTTP module. The byterange filter turned out to be very
HTTP specific, and it belongs in the HTTP module. [Greg Stein]
*) Make clean, distclean, and extraclean consistently according to the
Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
*) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
This may have been causing problems stopping processes in the threaded
mpm's. [Greg Ames]
*) Fix content-length in mod_negotiation to a long int representation.
[William Rowe]
*) Remove BindAddress from the default config file.
[giles@nemeton.com.au]
*) Allow module authors to add a module to their Apache build using
--with-module, without re-running buildconf. The syntax is:
--with-module=module_type:/path/to/module.c
The configure script will copy the module.c file to
modules/module_type, and it will be added to the relevant Makefiles.
currently, this only works for static modules. [Ryan Bloom]
*) Changes required to make prefork clean up idle children properly.
There was a window during which a starting worker deadlocks when
an idle cleanup arrives before it completes init. Apache then keeps
trying to cleanup the same deadlocked worker forever (until higher
pids come along, but it still will never reduce below the deadlocked
pid). Thus the number of children would not reduce to the correct
idle level. [Paul J. Reder]
Changes with Apache 2.0.16
*) Change the default installation directory to /usr/local/apache2,
as now defined by the "Apache" layout in config.layout. [Marc Slemko]
*) OS/2: Added support for building loadable modules as OS/2 DLLs.
[Brian Havard]
*) Get MaxRequestsPerChild working with the Windows MPM.
[Bill Stoddard]
*) Make generic hooks to work, with mod_generic_hook_import/export
experimental modules. [Ben Laurie, Will Rowe]
*) Fix segfaults for configuration file syntax errors such as
"<Directory>" followed by "</Directory" and
"<Directory>" followed by "</Directoryz>". [Jeff Trawick]
*) Cleanup the --enable-layout option of configure. This makes
us use a consistent location for the config.layout file, and it
makes configure more portable.
[jun-ichiro hagino <itojun@iijlab.net>]
*) Changes to 'ab'; fixed int overrun's, added statistics, output in
csv/gnuplot format, rudimentary ssl support and various other tweaks
to make results more true to what is measured. The upshot of this it
turns out that 'ab' has often underreported the true performance of
apache. Often by a order of magnitude :-) See talk/paper of Sander
Temme <sctemme@covalent.net> at April ApacheCon 2001 for details.
[Dirk-Willem van Gulik]
*) Clean up mod_cgid's temporary request pool. Besides fixing a
storage leak this ensures that some unnecessary pipes are closed.
[Jeff Trawick]
*) Performance: Add quick_handler hook. This hook is called at the
very beginning of the request processing before location_walk,
translate_name, etc. This hook is useful for URI keyed content
caches like Mike Abbott's Quick Shortcut Cache.
[Bill Stoddard]
*) top_module global variable renamed to ap_top_module [Perl]
*) Move ap_set_last_modified to the core. This is a potentially
controversial change, because this is kind of HTTP specific. However
many protocols should be able to take advantage of this kind of
information. I expect that headers will need one more layer of
indirection for multi-protocol work, but this is a small step in
the right direction. [Ryan Bloom]
*) Enable mod_status by default. This matches what Apache 1.3 does.
[Ed Korthof]
*) Add a ScriptSock directive to the default config file. This is
only enabled when mod_cgid is used.
[Taketo Kabe <kabe@sra-tohoku.co.jp>]
Changes with Apache 2.0.15
*) Untangled the buildconf script and eliminated the need for build's
aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
libtool muck that is now under srclib/apr/build. [Roy Fielding]
*) Win32: Don't accept more connections than we have worker threads
to handle.
[Bill Stoddard]
*) Fix bug in the Unix threaded.c MPM that allowed child processes
to fork() new child processes.
[Bill Stoddard]
*) Fix a major security problem with double-reverse lookup checking.
Previously, a client connecting over IPv4 would not be matched
properly when the server had an IPv6 listening socket. PR #7407
[Taketo Kabe <kiabe@sra-tohoku.co.jp>]
*) Change the way the beos MPM handles polling to allow it to stop and
restart. Problem was the sockets being polled were being reset by
the select call, so once it had accepted a connection it was no
longer listening on the UDP socket we use for shutdown instructions.
APR needs to be altered, patch on it's way. [David Reid]
*) Empty out the brigade shared by ap_getline()/ap_get_client_block()
on error exit from ap_getline(). Some other code got upset because
the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
*) Handle ap_discard_request_body() being called more than once.
[Greg Ames, Jeff Trawick]
*) Get rid of an inadvertent close of file descriptor 2 in
mod_mime_magic. [Greg Ames, Jeff Trawick]
*) Add a hook, create_request. This hook allows modules to modify
a request while it is being created. This hook is called for all
request_rec's, main request, sub request, and internal redirect.
When this hook is called, the the r->main, r->prev, r->next
pointers have been set, so modules can determine what kind of
request this is. [Ryan Bloom]
*) Cleanup the build process a bit more. The Apache configure
script no longer creates its own helper scripts, it just
uses APR's.
[jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
*) Stop the forced downgrade of the connection to HTTP/1.0 for
proxy requests. [Graham Leggett]
*) Avoid using sscanf to determine the HTTP protocol number in
the common case because sscanf is a performance hog. From
Mike Abbot's Accelerating Apache patch number 6.
[Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
*) Fix a security exposure in mod_access. Previously when IPv6
listening sockets were used, allow/deny-from-IPv4-address rules
were not evaluated properly (PR #7407). Also, add the ability to
specify IPv6 address strings with optional prefix length on Allow
and Deny. [Jeff Trawick]
*) Enhance rotatelogs so that a UTC offset can be specified, and
the logfile name can be formatted using strftime(3). (Brought
forward from 1.3.) [Ken Coar]
*) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
DuplicateHandle on an IOCompletionPort (a practice which
MS "discourages"). The new model does not rely on associating
the completion port with the listening sockets, thus the
completion port can be completely managed within the child
process. A dedicated thread accepts connections off the network,
then calls PostQueuedCompletionStatus() to wake up worker
threads blocked on the completion port.
[Bill Stoddard]
*) Bring forward the --suexec-umask option which allows the
builder to preset the umask for suexec processes. [Ken Coar]
*) Add a -V flag to suexec, which causes it to display the
compile-time settings with which it was built. (Only
usable by root or the AP_HTTPD_USER username.) [Ken Coar]
*) Mod_include should always unset the content-length if the file is
going to be passed through send_parsed_content. There is no to
determine if the content will change before actually scanning the
entire content. It is far safer to just remove the C-L as long
as we are scanning it. [Ryan Bloom]
*) Make sure Apache sends WWW-Authenticate during a reverse proxy
request and not Proxy-Authenticate.
[Graham Leggett <minfrin@sharp.fm>]
Changes with Apache 2.0.14
*) Fix content-length computation. We ONLY compute a content-length if
We are not in a 1.1 request and we cannot chunk, and this is a keepalive
or we already have all the data. [Ryan Bloom]
*) Report unbounded containers in the config file. Previously, a typo
in the </container> directive could result in the rest of the config
file being silently ignored, with undesired defaults used.
[Jeff Trawick]
*) Make the old_write filter use the ap_f* functions for the buffering.
[Ryan Bloom]
*) Move more code from the http module into the core server. This
is core code, basically the default handler, the default input
and output filters, and all of the core configuration directives.
All of this code is required in order for the server to work, with or
without HTTP. The server is closer to working without the HTTP
module, although there is still more to do. [Ryan Bloom]
*) Fix a number of SGI compile warnings throughout the server. Fix some
bad parameters to apr_bucket_read(). Fix a bad statement in
ap_method_in_list(). For the mod_rewrite cache use apr_time_t
consistently; we were mixing apr_time_t and time_t in invalid ways
before. In load_file(), call apr_dso_error() instead of
apr_strerror() so that we get a more specific string on some platforms.
PR #6980 [Jeff Trawick]
*) Allow modules to query the MPM about it's execution profile. This
query API can and should be extended in the future, but for now,
max_daemons, and threading or forking is a very good start.
[Jon Travis <jtravis@covalent.net>]
*) Modify mod_include to send blocks of data no larger than 9k.
Without this, mod_include will wait until the whole file is parsed,
or the first tag is found to send any data to the client.
[Paul J. Reder <rederpj@raleigh.ibm.com>]
*) Fix mod_info, so that <Directory> and <Location> directives are
not displayed twice when displaying the current configuration.
[Ryan Morgan <rmorgan@covalent.net>]
*) Add config directives to override DEFAULT_ERROR_MSG and
DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
[Dan Rench <drench@xnet.com>]
*) Get mod_info building and loading on Win32. [William Rowe]
*) Begin to move protocol independant functions out of mod_http. The goal
is to have only functions that are HTTP specific in the http directory.
[Ryan Bloom]
Changes with Apache 2.0.13
*) Don't assume that there will always be multiple calls to the byterange
filter. It is possible that we will need to do byteranges with only
one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
*) Move the error_bucket definition from the http module to the
core server. Every protocol will need this ability, not just
HTTP. [Ryan Bloom]
Changes with Apache 2.0.12
*) Modify mod_file_cache to save pre-formatted strings for
content-length and last-modified headers for performance.
[Mike Abbot <mja@trudge.engr.sgi.com>]
*) Namespace protect IOBUFSIZ since it is exposed in the API.
[Jon Travis <jtravis@covalent.net>]
*) Use "Basic" authentication instead of "basic" in ab, as the spec
says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
*) Fix a seg fault in mod_userdir.c. We used to use the pw structure
without ever filling it out. This fixes PR 7271.
[Taketo Kabe <kabe@sra-tohoku.co.jp> and
Cliff Woolley <cliffwoolley@yahoo.com>]
*) Add a couple of GCC attribute tags to printf style functions.
[Jon Travis <jtravis@covalent.net>]
*) Add the correct language tag for interoperation with the Taiwanese
versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
*) Migrate the perchild MPM to use the new apr signal child, and
APR thread functions. [Ryan Bloom]
*) Close one copy of the CGI's stdout before creating the new process.
The CGI will still have stdout, because we have already dup'ed it.
This keeps Apache from waiting forever to send the results of a CGI
process that has forked a long-lived child process.
[Taketo Kabe <kabe@sra-tohoku.co.jp>]
*) Remove the rest of the pthreads functions from the threaded MPM.
This requires the APR support for a signal thread that was just
added. [Ryan Bloom]
*) Make mod_dir use a fixup for sending a redirect to the browser.
Before this, we were using a handler, which doesn't make much
sense, because the handler wasn't generating any data, it would
either return a redirect error code, or DECLINED. This fits the
current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
*) Make the threaded MPM use APR threads instead of pthreads.
[Ryan Bloom]
*) Get mod_tls to the point where it actually appears to work in all cases.
[Ben Laurie]
*) implement --enable-modules and --enable-mods-shared for "all" and
"most". [Greg Stein]
*) Move the threaded MPM to use APR locks instead of pthread locks.
[Ryan Bloom]
*) Rename mpmt_pthread to threaded. This is more in line with the
fact that mpmt_pthread shouldn't be using pthreads directly, and
it is a smaller name that doesn't tie into anything.
[Ryan Bloom]
*) Rename the module structures so that the exported symbol matches
the file name, and it is easier to automate the installation
process (generating LoadModule directives from the module filenames).
[Martin Kraemer]
*) Remove the coalesce filter. With the ap_f* functions, this filter
is no longer needed. [Ryan Bloom]
Changes with Apache 2.0.11
*) Remove the dexter MPM. Perchild is the same basic idea, but it has the
added feature of allowing a uid/gid per child process. If no
uid/gid is specified, then Perchild behaves exactly like dexter.
[Ryan Bloom]
*) Get perchild building again. [Ryan Bloom]
*) Don't disable threads just because we are using the prefork MPM.
If somebody wants to compile without threads, they must now add
--disable-threads to the configure command line. [Ryan Bloom]
*) Begin to move the calls to update_child_status into common code, so
that each individual MPM does not need to update the scoreboard itself.
[Ryan Bloom]
*) Allow mod_tls to compile under Unix boxes where openssl has been
installed to the system include files.
[Gomez Henri <new-httpd@slib.fr>]
*) Cleanup the mod_tls configure process. This should remove any need
to hand-edit any files. We require OpenSSL 0.9.6 or later, but
configure doesn't check that yet. [Ryan Bloom]
*) Add a very early prototype of SSL support (in mod_tls.c). It is
vital that you read modules/tls/README before attempting to build
it. [Ben Laurie]
*) Fix a potential seg fault on all platforms. David Reid fixed this
on BEOS, but the problem could happen anywhere, so we don't want
to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
*) Add new LogFormat directive, %D, to log time it takes to serve a
request in microseconds. [Bill Stoddard]
*) Change AddInputFilter and AddOutputFilter to SetInputFilter and
SetOutputFilter. This corresponds nicely with the other Set
directives, which operate on containers while the Add* directives
tend to work directly on extensions. [Ryan Bloom]
*) Cleanup the header handling a bit. This uses the apr_brigade_*
functions for the buffering so that we don't need to compute
the length of the headers before we actually create the header
buffer. [Ryan Bloom]
*) Allow filters to buffer data using the ap_f* functions. These have
become macros that resolve directly to apr_brigade_*.
[Ryan Bloom]
*) Get the Unix MPM's to do a graceful restart again. If we are going
to register a cleanup with ap_cleanup_scoreboard, then we have to
kill the cleanup with the same function, and that function can't be
static. [Ryan Bloom]
*) Install all required header files. Without these, it was not
possible to compile some modules outside of the server.
[Ryan Bloom]
*) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
forward from 1.3 to 2.0, we missed a single line, which broke regex
aliases. [Ryan Bloom]
*) We have a poor abstraction in the protocol. This is a temporary
hack to fix the bug, but it will need to be fixed for real. If
we find an error while sending out a custom error response, we back
up to the first non-OK request and send the data. Then, when we send
the EOS from finalize_request_protocol, we go to the last request,
to ensure that we aren't sending an EOS to a request that has already
received one. Because the data is sent on a different request than
the EOS, the error text never gets sent down the filter stack. This
fixes the problem by finding the last request, and sending the data
with that request. [Ryan Bloom]
*) Make the server status page show the correct restart time, and
thus the proper uptime. [Ryan Bloom]
*) Move the CGI creation logic from mod_include to mod_cgi(d). This
should reduce the amount of duplicate code that is required to
create CGI processes.
[Paul J. Reder <rederpj@raleigh.ibm.com>]
*) ap_new_connection() closes the socket and returns NULL if a socket
call fails. Usually this is due to a connection which has been
reset. [Jeff Trawick]
*) Move the Apache version information out of httpd.h and into release.h.
This is in preparation for the first tag with the new tag and release
system. [Ryan Bloom]
*) Begin restructuring scoreboard code to enable adding back in
the ability to use IPC other than shared memory.
Get mod_status working on Windows again. [Bill Stoddard]
*) Make mod_status work with 2.0. This will work for prefork,
mpmt_pthread, and dexter. [Ryan Bloom]
*) Correct a typo in httpd.conf.
[Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
*) Really fix mod_rewrite map lookups this time. [Tony Finch]
*) Get the correct IP address if ServerName isn't set and we can't
find a fully-qualified domain name at startup.
PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
*) Make mod_cgid work with SuExec. [Ryan Bloom]
*) Adopt apr user/group name features for mod_rewrite. Eliminates some
'extra' stat's for user/group since they should never occur, and now
resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
volumes. [William Rowe]
*) Adopt apr features to simplify mod_includes. This changes the
behavior of the USER_NAME variable, unknown uid's are now reported
as USER_NAME="<unknown>" rather than the old user#000 result.
WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
*) Adopt apr features for simplifing mod_userdir, and accept the new
Win32/OS2 exceptions without hiccuping. [William Rowe]
*) Replace configure --with-optim option by using and saving the
environment variable OPTIM instead. This is needed because configure
options do not support multiple flags separated by spaces.
[Roy Fielding]
*) Fix some byterange handling. If we get a byte range that looks like
"-999999" where that is past the end of the file, we should return
a PARTIAL CONTENT status code, and return the whole file as one big
byterange. This matches the 1.3 handling now. [Ryan Bloom]
*) Make the error bucket a real meta-data bucket. This means that the
bucket length is 0, and a read returns NULL data. If one of these
buckets is passed down after the headers are sent, this data will
just be ignored. [Greg Stein]
*) The prefork MPM wasn't killing child processes correctly if a restart
signal was received while the process was serving a request. The child
process would become the equivalent of a second parent process. If
we break out of the accept loop, then we need to do die after cleaning
up after ourselves. [Ryan Bloom]
*) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
restarts. [Ryan Bloom]
*) Modify the apr_stat/lstat/getfileinfo calls within apache to use
the most optimal APR_FINFO_wanted bits. This spares Win32 from
performing very expensive owner, group and permission lookups
and allows the server to function until these apr_finfo_t fields
are implemented under Win32. [William Rowe]
*) Support for typedsafe optional functions - that is functions exported by
optional modules, which, therefore, may or may not be present, depending
on configuration. See the experimental modules mod_optional_fn_{ex,im}port
for sample code. [Ben Laurie]
*) filters can now report an HTTP error to the server. This is done
by sending a brigade where the first bucket is an error_bucket.
This bucket is a simple bucket that stores an HTTP error and
a string. Currently the string is not used, but it may be needed
to output an error log. The http_header_filter will find this
bucket, and output the error text, and then return
AP_FILTER_ERROR, which informs the server that the error web page
has already been sent. [Ryan Bloom]
*) If we get an error, then we should remove all filters except for
those critical to serving a web page. This fixes a bug, where
error pages were going through the byterange filter, even though
that made no sense. [Ryan Bloom]
*) Relax the syntax checking of Host: headers in order to support
iDNS. PR#6635 [Tony Finch]
*) Cleanup the byterange filter to use the apr_brigade_partition
and apr_bucket_copy functions. This removes a lot of very messy
code, and hopefully makes this filter more stable.
[Ryan Bloom]
*) Remove AddModule and ClearModuleList directives. Both of these
directives were used to ensure that modules could be enabled
in the correct order. That requirement is now gone, because
we use hooks to ensure that modules are in the correct order.
[Ryan Bloom]
*) When SuExec is specified, we need to add it to the list of
targets to be built. If we don't, then any changes to the
configuration won't affect SuExec, unless 'make suexec' is
specifically run. [Ryan Bloom]
*) Cleaned out open_file from mod_file_cache, as apr now accepts
the APR_XTHREAD argument to open a file for consumption by
parallel threads on win32. [William Rowe]
*) Correct a bug in determining when we follow symlinks. The code
expected a stat -1 result, not an apr_status_t positive error.
Also check if the APR_FINFO_USER fields are valid before we
follow the link. [William Rowe]
*) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
mpm_common.c. These functions are only valid on some platforms,
so they should not be in the main-line code. [Ryan Bloom]
*) Remove ap_chdir_file(). This function is not thread-safe,
and nobody is currently using it. [Ryan Bloom]
*) Do not try to run make depend if there are no .c files in the
current directory, doing so makes `make depend` fail.
[Ryan Bloom]
*) Update highperformance.conf to work with either prefork or
pthreads mpms. [Greg Ames]
*) Stop checking to see if this is a pipelined request if we know
for a fact that it isn't. Basically, if r->connection->keepalive == 0.
This keeps us from making an extra read call when serving a 1.0
request. [Ryan Bloom and Greg Stein]
*) Fix the handling of variable expansion look-ahead in mod_rewrite,
i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
*) Fix the RFC number mentioned when complaining about a missing
Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
*) Fix an endless loop in ab which occurred when ab was posting
and the server dropped the connection unexpectedly.
[Jeff Trawick]
*) Fix a segfault while handling request bodies in ap_http_filter().
This problem has been seen with mod_dav usage as well as with
requests where the body was just being discarded. [Jeff Trawick]
*) Some adjustment on the handling and automatic setting (via
hints.m4) of various compilation flags (eg: CFLAGS). Also,
add the capability to specify flags (NOTEST_CFLAGS and
NOTEST_LDFLAGS) which are used to compile Apache, but
not used during the configuration process. Useful for
flags like "-Werror". [Jim Jagielski]
*) Stop using environment variables to force debug mode or
no detach. We now use the -D command line argument to
specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
[Greg Stein, Ryan Bloom]
*) Change handlers to use hooks. [Ben Laurie]
*) Stop returning copies of filenames from both apr_file_t and
apr_dir_t. We pstrdup the filenames that we store in the
actual structures, so we don't need to pstrdup the strings again.
[Ryan Bloom]
*) mod_cgi: Fix some problems where the wrong error value was being
traced. [Jeff Trawick]
*) EBCDIC: Fix some missing ASCII conversion on some protocol data.
[Jeff Trawick]
*) Add generic hooks. [Ben Laurie]
*) Use a real pool to dup the error log descriptor. [Ryan Bloom]
*) Fix a segfault caused by mod_ext_filter when the external filter
program does not exist. [Jeff Trawick]
*) Fix an output truncation error when on an HTTP >= 1.0 request an
object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
was served through mod_charset_lite (or anything else that would
create a transient bucket in this size range). ap_bucket_make_heap()
silently failed (fixed), transient_setaside() discovered it, but
ap_save_brigade() ignored it (fixed). [Jeff Trawick]
*) Ignore \r\n or \n when using PEEK mode for input filters. The problem
is that some browsers send extra lines at the end of POST requests, and
we don't want to delay sending data back to the user just because the
browser isn't well behaved. [Ryan Bloom]
*) Get SuEXEC working again. We can't send absolute paths to suExec
because it refuses to execute those programs. SuEXEC also wasn't
always recognizing configuration changes made using the autoconf
setup. [Ryan Bloom]
*) Allow the buildconf process to find the config.m4 files in the correct
order. Basically, we can now name config.m4 files as config\d\d.m4,
and we will sort them correctly when inserting them into the build
process. [Ryan Bloom]
*) Get mod_cgid to use apr calls for creating the actual CGI process.
This also allows mod_cgid to use ap_os_create_priviledged_process,
thus allowing for SuExec execution from mod_cgid. Currently, we do
not support everything that standard SuExec supports, but at least
it works minimally now. [Ryan Bloom]
*) Allow SuExec to be configured from the ./configure command line.
[Ryan Bloom]
*) Update some of the docs in README and INSTALL to reflect some of
the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
*) If we get EAGAIN returned from the call to apr_sendfile, then we
need to call sendfile again. This gets us serving large files
such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
*) Get the support programs building cleanly again.
[Cliff Woolley <cliffwoolley@yahoo.com>]
*) The Apache/Win32 Apache.exe and dll's now live in bin. The
current directory logic now backs up over bin/ to determine the
server root from the Apache.exe path.
*) Apache/Win32 now follows the standard conventions of mod_foo.so
loadable modules, dynamic libs are all named libfoo.dll, and the
makefile.win populates the include, lib and libexec directories.
*) Apache is now IPv6-capable. On systems where APR supports IPv6,
Apache gets IPv6 listening sockets by default. Additionally, the
Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
numeric address strings (e.g., "Listen [fe80::1]:8080").
[Jeff Trawick]
*) Modify the install directory layout. Modules are now installed in
modules/. Shared libraries should be installed in libraries/, but
we don't have any of those on Unix yet. All install directories
are modifyable at configure time. [Ryan Bloom]
*) Install all header files in the same directory on Unix. [Ryan Bloom]
*) Get the functions in server/linked into the server, regardless of
which modules linked into the server. This uses the same hack
for Apache that we use for APR and apr-util to ensure all of the
necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
the scripts a bit easier.
[Ryan Bloom]
*) Rework the RFC1413 handling to make it thread-safe, use a timeout
on the query, and remove IPv4 dependencies. [Jeff Trawick]
*) Get all of the auth modules to the point that they will install and
be loadable into the server. Our new build/install mechanism expects
that all modules will have a common name format. The auth modules
didn't use that format, so we didn't install them properly.
[Ryan Bloom]
*) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
available. Use apr_getaddrinfo() instead. [Jeff Trawick]
*) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
*) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
after the end of the response. [Ryan Bloom]
*) Get byterange requests working with responses that do not have a
content-length. Because of the way byterange requests work, we have to
have all of the data before we can actually do the byterange, so we
can compute the content-length in the byterange filter.
[Ryan Bloom]
*) Get exe CGI's working again on Windows.
[Allan Edwards]
*) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
they keep track of whether or not their post config hook has been
called before. Instead of a static variable (which is replaced when
the DSO is loaded a second time), use userdata in the process pool.
[Jeff Trawick]
Changes with Apache 2.0a9
*) Win32 now requires perl to complete the final install step for users
to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
and installs the conf, htdocs and htdocs/manual directories.
[William Rowe]
*) Make mod_include use a hash table to associate directive tags with
functions. This allows modules to implement their own SSI tags easily.
The idea is simple enough, a module can insert it's own tag and function
combination into a hash table provided by mod_include. While mod_include
parses an SSI file, when it encounters a tag in the file, it does a
hash lookup to find the function that implements that tag, and passes
all of the relevant data to the function. That function is then
responsible for processing the tag and handing the remaining data back
to mod_include for further processing.
[Paul J. Reder <rederpj@raleigh.ibm.com>]
*) Get rid of ap_new_apr_connection(). ap_new_connection() now has
fewer parameters: the local and remote socket addresses were removed
from the parameter list because all required information is available
via the APR socket. [Jeff Trawick]
*) Distribution directory structure reorganized to reflect a
normal source distribution with external install targets.
[Roy Fielding]
*) The MPMs that need multiple segments of shared memory now create
two apr_shmem_t variables, one for each shared memory allocation.
the problem is that we can't determine how much memory will be required
for shared memory allocations once we try to allocate more than one
variable. The MM code automatically aligns the shared memory allocations,
so we end up needing to pad the amount of shared memory we want based
on how many variables will be allocated out of the shared memory segment.
It is just easier to create a second apr_shmem_t variable, and two
shmem memory blocks.
[Ryan Bloom]
*) Cleanup the export list a bit. This creates a single unified list of
functions exported by APR. The export list is generated at configure
time, and that list is then used to generate the exports.c file.
Because of the way the export list is generated, we only export those
functions that are valid on the platform we are building on.
[Ryan Bloom]
*) Enable logging the cookie with mod_log_config
[Sander van Zoest <sander@covalent.net>]
*) Fix a segfault in mod_info when it reaches the end of the configuration.
[Jeff Trawick]
*) Added lib/aputil/ as a placeholder for utility functions which are not
specific to the Apache HTTP Server (but do not make sense with APR).
The first utility is "apu_dbm": a set of functions to work with DBM
files. This first version can be compiled for SDBM or GDBM databases.
[Greg Stein]
*) Complete re-write of mod_include. This makes mod_include a filter that
uses buckets directly. This has now served the FAQ correctly.
[Paul Reder <rederpj@raleigh.ibm.com>]
*) Allow modules to specify the first filter in a sub_request when
making the sub_request. This keeps modules from having to change the
output_filter immediately after creating the sub-request, and therefore
skip the sub_req_output_filter. [Ryan Bloom]
*) Update ab to accept URLs with IPv6 literal address strings (in the
format described in RFC 2732), and to build Host header fields in
the same format. This allows IPv6 literal address strings to be
used with ab. This support has been tested against Apache 1.3 with
the KAME patch, but Apache 2.0 does not yet work with this format
of the Host header field. [Jeff Trawick]
*) Accomodate an out-of-space condition in the piped logs and the
rotatelogs.c code, and no longer churn log processes for this
condition. [Victor J. Orlikowski]
*) Add support for partial writes with apr_sendfile() to core_output_filter.
[Greg Ames]
Changes with Apache 2.0a8
*) Add a directive to mod_mime so that filters can be associated with
a given mime-type.
[Ryan Bloom]
*) Get multi-views working again. We were setting the path_info
field incorrectly if we couldn't find the specified file.
[Ryan Bloom]
*) Fix 304 processing. The core should never try to send the headers
down the filter stack. Always, just setup the table in the request
record, and let the header filter convert it to data that is ready
for the network.
[Ryan Bloom]
*) More fixes for the proxy. There are still bugs in the proxy code,
but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
successfully.
[Ryan Bloom]
*) Fix params for apr_getaddrinfo() call in connect proxy handler.
[Chuck Murcko]
*) APR: Add new apr_getopt_long function to handle long options.
[B. W. Fitzpatrick <fitz@red-bean.com>]
*) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
hostname resolution/address string parsing and building
apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
of one of the apr_sockaddr_t structures for a socket. Change
apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
*) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
I have proxied pages with it, cleanup will commence soon.
[Ryan Bloom]
*) Make the proxy work with filters. This isn't perfect, because we
aren't dealing with the headers properly. [Ryan Bloom]
*) Do not send a content-length iff the C-L is 0 and this is a head
request. [Ryan Bloom]
*) Make cgi-bin work as a regular directory when using mod_vhost_alias
with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
*) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
*) Get the default_handler to stop trying to deal with HEAD requests.
The idea is to let the content-length filter compute the C-L before
we try to send the data. If we can get the C-L correctly, then we
should send it in the HEAD response.
[Ryan Bloom]
*) The Header filter can now determine if a body should be sent based
on r->header_only. The general idea of this is that if we delay
deciding to send the body, then we might be able to compute the
content-length correctly, which will help caching proxies to cache
our data better. Any handler that doesn't want to try to compute
the content-length can just send an EOS bucket without data and
everything will just work.
[Ryan Bloom]
*) Add the referer to the error log if one is available.
[Markus Gyger <mgyger@itr.ch>]
*) Mod_info.c has now been ported to Apache 2.0. As a part of this
change, the root of the configuration tree has been exposed to modules
as ap_conftree.
[Ryan Morgan <rmorgan@covalent.net>]
*) Get the core_output_filter to use the bucket interface directly.
This keeps us from calling the content-length filter multiple times
for a simple static request.
[Ryan Bloom]
*) We are sending the content-type correctly now.
[Ryan Bloom and Will Rowe]
*) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
a bogus bytes-sent value when the only thing being sent was trailers
and writev() returned an error (or EAGAIN). [Jeff Trawick]
*) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
hints file to determine which platforms define
SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
[Ryan Bloom]
*) APR: add apr_get_home_directory() [Jeff Trawick]
*) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
*) Not all platforms have INADDR_NONE defined by default. Apache
used to make this check and define INADDR_NONE if appropriate,
but APR needs the check too, and I suspect other applications will
as well. APR now defines APR_INADDR_NONE, which is always a valid
value on all platforms.
[Branko <20>ibej <brane@xbc.nu>]
*) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
[Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
*) Relax the syntax checking of Host: headers in order to support
iDNS. PR#6635 [Tony Finch]
*) When reading from file buckets we convert to an MMAP if it makes
sense. This also simplifies the default handler because the
default handler no longer needs to try to create MMAPs.
[Ryan Bloom]
*) BUFF has been removed from the main server. The BUFF code will remain
in the code until it has been purged from the proxy module as well.
[Ryan Bloom]
*) Byteranges have been completely re-written to be a filter. This
has been tested, and I believe it is working correctly, but it could
doesn't work for the Adobe Acrobat plug-in. The output almost matches
the output from 1.3, the only difference being that 1.3 includes
a content-length in the response, and this does not.
[Ryan Bloom]
*) APR read/write functions and bucket read functions now operate
on unsigned integers, instead of signed ones. It doesn't make
any sense to use signed ints, because we return the error codes,
so if we have an error we should report 0 bytes read or written.
[Ryan Bloom]
*) Always compute the content length, whether it is sent or not.
The reason for this, is that it allows us to correctly report
the bytes_sent when logging the request. This also simplifies
content-length filter a bit, and fixes the actual byte-reporing
code in mod_log_config.c
[Ryan Bloom]
*) Remove AP_END_OF_BRIGADE definition. This does not signify what
it says, because it was only used by EOS and FLUSH buckets. Since
neither of those are required at the end of a brigade, this was
really signifying FLUSH_THE_DATA, but that can be determined better
by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
buckets now return a length of 0, which is actually the amount of data
read, so they make more sense.
[Ryan Bloom]
*) Allow the core_output_filter to save some data past the end of a
request. If we get an EOS bucket, we only send the data if it
makes sense to send it. This allows us to pipeline request
responses. As a part of this, we also need to allocate mmap
buckets out of the connection pool, not the request pool. This
allows the mmap to outlive the request.
[Ryan Bloom]
*) Make blocking and non-blocking bucket reads work correctly for
sockets and pipes. These are the only bucket types that should
have non-blocking reads, because the other bucket types should
ALWAYS be able to return something immediately.
[Ryan Bloom]
*) In the Apache/Win32 console window, accept Ctrl+C to stop the
server, but use Ctrl+Break to initiate a graceful restart
instead of duplicating behavior. [John Sterling]
*) Patch mod_autoindex to set the Last-Modified header based on
the directory's mtime, and add the ETag header. [William Rowe]
*) Merge the 1.3 patch to add support for logging query string in
such a way that "%m %U%q %H" is the same as "%r".
[Bill Stoddard]
*) Port three log methods from mod_log_config 1.3 to 2.0:
CLF compliant '-' byte count, method and protocol.
[Bill Stoddard]
*) Add a new LogFormat directive, %c, that will log connection
status at the end of the response as follows:
'X' - connection aborted before the response completed.
'+' - connection may be kept-alive by the server.
'-' - connection will be closed by the server.
[Bill Stoddard]
*) Expand APR for WinNT to fully accept and return utf-8 encoded
Unicode file names and paths for Win32, and tag the Content-Type
from mod_autoindex to reflect that charset if the the feature
macro APR_HAS_UNICODE_FS is true. [William Rowe]
*) Compute the content length (and add appropriate header field) for
the response when no content length is available and we can't use
chunked encoding. [Jeff Trawick]
*) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
so that content input filters get dechunked data when using
the default handler. Also removed REQUEST_CHUNKED_PASS.
[Sascha Schumann]
*) Add mod_ext_filter as an experimental module. This module allows
the administrator to use external programs as filters. Currently,
only filtering of output is supported. [Jeff Trawick]
*) Most Apache functions work on EBCDIC machines again, as protocol
data is now translated (again). [Jeff Trawick]
*) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
the EBCDIC support. They are noops on ASCII machines, so this
type of translation doesn't have to be surrounded by #ifdef
CHARSET_EBCDIC. [Jeff Trawick]
*) Fix mod_include. tag commands work again, and the server will
send the FAQ again. This also allows mod_include to set aside
buckets that include partial buckets.
[Ryan Bloom and David Reid]
*) Add suexec support back. [Manoj Kasichainula]
*) Lingering close now uses the socket directly instead of using
BUFF. This has been tested, but since all we can tell is that it
doesn't fail, this needs to be really hacked on.
[Ryan Bloom]
*) Allow filters to modify headers and have those headers be sent to
the client. The idea is that we have an http_header filter that
actually sends the headers to the network. This removes the need
for the BUFF to send headers.
[Ryan Bloom]
*) Charset translation: mod_charset_lite handles translation of
request bodies. Get rid of the xlate version of ap_md5_digest()
since we don't compute digests of filtered (e.g., translated)
response bodies this way anymore. (Note that we don't do it at
all at the present; somebody needs to write a filter to do so.)
[Jeff Trawick]
*) Input filters and ap_get_brigade() now have a input mode parameter
(blocking, non-blocking, peek) instead of a length parameter.
[hackathon]
*) Update the mime.types file to the registered media types as
of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
Tony Finch]
*) Namespace protect some macros declared in ap_config.h
[Ryan Bloom]
*) Support HTTP header line folding with input filtering.
[Greg Ames]
*) Mod_include works again. This should still be re-written, but at
least now we can serve an SHTML page again.
[Ryan Bloom]
*) Begin to remove BUFF from the core. Currently, we keep a pointer
to both the BUFF and the socket in the conn_rec. Functions that
want to use the BUFF can, functions that want to use the socket,
can. They point to the same place.
[Ryan Bloom]
*) apr_psprintf doesn't understand %lld as a format. Make it %ld.
[Tomas "<22>gren" <stric@ing.umu.se>]
*) APR pipes on Unix and Win32 are now cleaned up automatically when the
associated pool goes away. (APR pipes on OS/2 were already had this
logic.) This resolvs a fatal file descriptor leak with CGIs.
[Jeff Trawick]
*) The final line of the config file was not being read if there was
no \n at the end of it. This was caused by apr_fgets returning
APR_EOF even though we had read valid data. This is solved by
making cfg_getline check the buff that was returned from apr_fgets.
If apr_fgets return APR_EOF, but there was data in the buf, then we
return the buf, otherwise we return NULL.
[Ryan Bloom]
*) Piped logs work again in the 2.0 series.
[Ryan Bloom]
*) Restore functionality broken by the mod_rewrite security fix:
rewrite map lookup keys and default values are now expanded
so that the lookup can depend on the requested URI etc.
PR #6671 [Tony Finch]
*) Tighten up the syntax checking of Host: headers to fix a
security bug in some mass virtual hosting configurations
that can allow a remote attacker to retrieve some files
on the system that should be inaccessible. [Tony Finch]
*) Add a pool bucket type. This bucket is used for data allocated out
of a pool. If the pool is cleaned before the bucket is destroyed, then
the data is converted to a heap bucket, allowing it to survive the
death of the pool.
[Ryan Bloom]
*) Add a flush bucket. This allows modules to signal that the filters
should all flush whatever data they currently have. There is no way
to actually force them to do this, so if a filter ignores this bucket,
that's life, but at least we can try with this.
[Ryan Bloom]
*) Add an output filter for sub-requests. This filter just strips the
EOS bucket so that we don't confuse the main request's core output
filter by sending multiple EOS buckets. This change also makes sub
requests start to send EOS buckets when they are finished.
[Ryan Bloom]
*) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
makes ap_bucket_destroy a return void, which is okay because it
used to always return APR_SUCCESS, and nobody ever checked its
return value anyway.
[Cliff Woolley <cliffwoolley@yahoo.com>]
*) Remove the index into the bucket-type table from the buckets
structure. This has now been replaced with a pointer to the
bucket_type. Also add some macros to test the bucket-type.
[Ryan Bloom]
*) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
All _VAR_ flavors changes to _DATA to be absolutely clear.
[William Rowe]
*) Add support for /, //, //servername and //server/sharename
parsing of <Directory> blocks under Win32 and OS2.
[Tim Costello, William Rowe, Brian Harvard]
*) Remove the function pointers from the ap_bucket type. They have been
replaced with a global table. Modules are allowed to register bucket
types and use then use those buckets.
[Ryan Bloom]
*) mod_cgid: In the handler, shut down the Unix socket (only for write)
once we finish writing the request body to the cgi child process;
otherwise, the client doesn't hit EOF on stdin. Small request bodies
worked without this change (for reasons I don't understand), but large
ones didn't. [Jeff Trawick]
*) Remove file bucket specific information from the ap_bucket type.
This has been moved to a file_bucket specific type that hangs off
the data pointer in the ap_bucket type.
[Ryan Bloom]
*) Input filtering now has a third argument. This is the amount of data
to read from lower filters. This argument can be -1, 0, or a positive
number. -1 means give me all the data you have, I'll deal with it and
let you know if I need more. 0 means give me one line and one line
only. A positive number means I want no more than this much data.
Currently, only 0 and a positive number are implemented. This allows
us to remove the remaining field from the conn_rec structure, which
has also been done.
[Ryan Bloom]
*) Big cleanup of the input filtering. The goal is that http_filter
understands two conditions, headers and body. It knows where it is
based on c->remaining. If c->remaining is 0, then we are in headers,
and http_filter returns a line at a time. If it is not 0, then we are
in body, and http_filter returns raw data, but only up to c->remaining
bytes. It can return less, but never more.
[Greg Ames, Ryan Bloom, Jeff Trawick]
*) mod_cgi: Write all of the request body to the child, not just what
the kernel would accept on the first write. [Jeff Trawick]
*) Back out the change that moved the brigade from the core_output_filters
ctx to the conn_rec. Since all requests over a given connection
go through the same core_output_filter, the ctx pointer has the
correct lifetime.
[Ryan Bloom]
*) Fix another bug in the send_the_file() read/write loop. A partial
send by apr_send would cause unsent data in the read buffer to
get clobbered. Complete making send_the_file handle partial
writes to the network.
[Bill Stoddard]
*) Fix a couple of type fixes to allow compilation on AIX again
[Victor J. Orlikowski <v.j.orlikowski@gte.net>]
*) Fix bug in send_the_file() which causes offset to be ignored
if there are no headers to send.
[Bill Stoddard]
*) Handle APR_ENOTIMPL returned from apr_sendfile in the core
filter. Useful for supporting Windows 9* with a binary
compiled on Windows NT.
[Bill Stoddard]
Changes with Apache 2.0a7
*) Reimplement core_output_filter to buffer/save bucket brigades
across multiple calls to the core_filter. The brigade will be
sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
thresholds are hit or the EOS bucket is received.
[Bill Stoddard]
*) Create experimental filter (buffer_filter) that coalesces bytes
into one large buffer before invoking the next filter in the
chain. This filter is particularly useful with the current
implementation of mod_autoindex when it inserted above the
chunk_filter. mod_autoindex generates a lot of brigades that
containing buckets holding just a few bytes each. The
buffer_filter coalesces these buckets into a single large bucket.
[Bill Stoddard]
*) Add apr_sendfile() support into the core_output_filter.
[Bill Stoddard]
*) Add apr_sendv() support into the core_output_filter.
[Bill Stoddard]
*) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
[Mike Abbott <mja@sgi.com>]
*) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
make much sense, because Apache uses buckets instead of BUFFs now.
[Ryan Bloom]
*) send_the_file now falls back to a read/write loop on platforms that
do not have sendfile.
[Ryan Bloom and Brian Havard]
*) Install apachectl correctly, and substitute the proper values so
that it works again. [Ryan Bloom]
*) Better(??) handle platforms that lack sendfile().
[Jim Jagielski]
*) APR now has UUID generation/formatting/parsing support.
[Greg Stein]
*) Begin the http_filter. This is an input filter that understands
the absolute basic amount required to parse an HTTP Request. The
goal is to be able to split headers from request body before passing
the data back to the other filters.
[Ryan Bloom]
*) Bring forward from 1.3.13 the config directory implementation
[Jim Jagielski]
*) install apxs if it is created
[Ryan Bloom]
*) Added APR_IS_STATUS_condition test macros to eliminate canonical error
conversions. [William Rowe]
*) Now that we have ap_add_input_filter(), rename ap_add_filter() to
ap_add_output_filter(). [Jeff Trawick]
*) Multiple build and configuration fixes
Build process:
-add datadir and localstatedir substitutions
-fix layout name
-fix logfilename misspelling
-fix evaluation of installation dir variables and
-replace $foobar by $(foobar) to be usefull in the makefile
Cross compile:
-add rules for cross-compiling in rules.mk. Okay, rule to check for
$CC_FOR_BUILD is still missing
-use CHECK_TOOL instead of CHECK_PROG for ranlib
-add missing "AR=@AR@" to severaly Makefile.in's
-cache result for "struct rlimit"
-compile all helper programs with native and cross compiler
and use the native version to generate header file
["R<>diger" Kuhlmann <Tadu@gmx.de>]
*) Prepare our autoconf setup for autoconf 2.14a and for cross-
compiling.
["R<>diger" Kuhlmann <Tadu@gmx.de>]
*) Fix a bug where a client which only sends \n to delimit header
lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
message. Start working on ebcdic co-existance with input
filtering.
[William Rowe, Greg Ames]
*) If mod_so is enabled in the server always create libexec, even
if there are no modules installed in this directory. This is a
requirement for APXS to work correctly.
[Ryan Bloom]
*) Connection oriented output filters are now stored in the
conn_rec instead of the request_rec. This allows us to add the
output filter in the pre-connection phase instead of the
post_read_request phase, which keeps us from trying to write an
error page before we have a filter to write to the network.
[Ryan Bloom, Jeff Trawick, and Greg Ames]
*) Cleaning up an mmap bucket no longer deletes the mmap. An
mmap can be used across multiple buckets (default_handler with
byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
the mmap itself can't be associated with the bucket.
[Jeff Trawick]
*) Add .dll caching directive ISAPICacheFile to mod_isapi.
[William Rowe]
*) Radical surgery to improve mod_isapi support under Win32.
Includes a number of newer ServerSupportFunction calls, support
for ReadClient (in order to retrieve POSTs greater than 48KB),
and general bug fixes to more reliably load ISAPI .dll's and
prevent leaking handle resources. Note: There are still
discrepancies between IIS's and Apache's ServerVariables, and
async calls are still not supported. Additional warnings are
logged to facilitate debugging of unsupported ISAPI calls.
[William Rowe]
*) Add input filtering to Apache. The basic idea for the input
filters is the same as the ideas for output filters. The biggest
difference is that instead of calling ap_pass_brigade, ap_get_brigade
should be called, and the order of execution for the filter itself is
different. When writing an output filter, a brigade is passed in,
and filters operate directly on that brigade, when done, they call
ap_pass_brigade. Input filters are the exact opposite. Because input
is not a push operation, filters first call ap_get_brigade. When this
function returns, the input filter will be left with a valid brigade.
The input filter should then operate on the brigade, and return.
[Ryan Bloom]
*) Fix building on BSD/OS using its native make. The build system
falls back to the BSD .include directive on that host platform.
[Sascha Schumann]
*) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
SHA1 and plaintext password encodings. Make feature tests a
bit more flexible. [William Rowe]
*) Charset translation: mod_charset_lite handles output content
translation in a filter. mod_charset_lite no longer ignores
subrequests. A bunch of cruft related to BUFF's support for
translating request and response bodies was removed.
[Jeff Trawick]
*) Move the addition of the CORE filter to the post_read_request
hook in http_core.c. This removes the need to add the filter in
multiple places and allows for an SSL module to be added much
simpler. [Ryan Bloom]
*) Fix a security problem that affects certain configurations of
mod_rewrite. If the result of a RewriteRule is a filename that
contains expansion specifiers, especially regexp backreferences
$0..$9 and %0..%9, then it may be possible for an attacker to
access any file on the web server. [Tony Finch]
*) Fix a bug where errors that are detected during early request parsing
don't produce visible HTTP error messages at the browser, because
the core_filter wasn't present. [Greg Ames]
*) Provide apr_socklen_t as a portability aid.
[Victor J. Orlikowski]
*) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
as well as a comment arg to the add, adduser and update cmds.
update allows the user to clear or preserve pw/groups/comment.
Fixed a bug in dbmmanage that prevented the check option from
parsing a password followed by :group... text. Corrected the
seed calcualation for Win32 systems, and added -lsdbm support.
[William Rowe]
*) Configured mod_auth_dbm to compile with sdbmlib under Win32.
[William Rowe]
*) Avoid a segfault when parsing .htaccess files. An
uninitialized tree pointer was passed to ap_build_config().
[Jeff Trawick]
*) Change the way that inet_addr & inet_network are checked for
in APR's configure process to allow BeOS BONE to correctly
find them. With this change BeOS BONE now builds from source
with no problems. [David Reid]
*) Fix a bug in apr_create_process() for Unix. The NULL signifying
the end of the parameters to execve() was stored in the wrong
location, overlaying the storage beyond the newargs[] array and
also passing uninitialized storage to execve(), which would
sometimes fail with EFAULT. [Jeff Trawick]
*) Fix a bug parsing configuration file containers. With a sequence
like this in the config file
<IfModule mod_kilroy.c>
any stuff
</IfModule>
<IfModule mod_lovejoy.c>
(blank line)
any stuff
</IfModule>
the second container would be terminated at the blank line due to
sediment in the buffer from reading the prior </IfModule> and an
error message would be generated for the real </IfModule> for the
second container. Also due to this problem, any two characters
could be used for "</" in the close of a container.
[Jeff Trawick]
*) ap_add_filter prototype changed to remove the ctx pointer. The
pointer still remains in the filter structure, but it can not be
a part of the ap_add_filter prototype. The reason is that when
the core uses AddFilter to add a filter to the stack it doesn't
know how to allocate the ctx pointer, or even how much memory should
be allocated. The filters will have to be responsible for allocating
the ctx memory when they need it.
[Ryan Bloom]
*) Add an AddFilter directive. This directive takes a list of filters
that should be activated for the requested resource.
[Ryan Bloom]
*) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
some other platforms). [Jeff Trawick]
*) Modify mod_include to be a filter. Currently, it has only been tested
on actual files, but it should work for CGI scripts too.
[Ryan Bloom]
*) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
writes. apr_flush() for Unix: handle interrupted writes.
[Jeff Trawick]
*) NameVirtualHost can now take "*" as an argument instead of
an IP address. This allows you to create a purely name-based
virtual hosting server that does not have any IP addresses in
the configuration file and which ignores the local address
of any connections. PR #5595, PR #4455 [Tony Finch]
*) Fix some compile warnings in mod_mmap_static.c
[Mike Abbott <mja@sgi.com>]
*) Fix chunking problem with CGI scripts. The general problem was that
the CGI modules were adding an EOS bucket and then the core added an
EOS bucket. The chunking filter finalizes the chunked response when it
encounters an EOS bucket. Because two EOS buckets were sent, we
finalized the response twice. The fix is to make sure we only send one
EOS, by utilizing a flag in the request_rec.
[Ryan Bloom]
*) apr_put_os_file() now sets up the unget byte appropriately on Unix
and Win32. Previously, the first read from an apr_file_t set up via
apr_put_os_file() would return a '\0'. [Jeff Trawick]
*) Mod_cgid now creates a single element bucket brigade, with a pipe
bucket, instead of using BUFF's and ap_r*.
[Ryan Bloom]
*) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
[Mike Abbott <mja@sgi.com>]
*) Remove ap_bopenf from buff code. This required modifying the file_cache
code to use APR file's directly instead of going through BUFFs.
[Ryan Bloom]
*) Fix compile break on some platforms for mod_mime_magic.c
[John K. Sterling <sterling@covalent.net>]
*) Fix merging of AddDefaultCharset directive.
PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
*) Minor revamp of the rlimit sections of code. We now test
explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
is now "available" even if the platform doesn't support
the rlimit family (it's just a noop though). [Jim Jagielski]
*) Migrate the pre-selection of which MPM to use for specific
platforms to hints.m4, which contains (or should contain)
all platform specific "hints". [Jim Jagielski]
*) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
[Ryan Bloom]
*) Add tables with non-string/binary values to APR.
[Ken Coar]
*) Fix some bad calls to ap_log_rerror() in mod_rewrite.
[Jeff Trawick]
*) Update PCRE to version 3.2. [Ryan Bloom]
*) Change the way buckets' destroy functions are called so that
they can be more directly used when changing the type of a
bucket in place. [Tony Finch]
*) Add generic support for reference-counting the resources used by
buckets, and alter the HEAP and MMAP buckets to use it. Change
the way buckets are initialised to support changing the type of
buckets in place, and use it when setting aside TRANSIENT buckets.
Change the implementation of TRANSIENT buckets so that it can be
mostly shared with IMMORTAL buckets, which are now implemented.
[Tony Finch]
Changes with Apache 2.0a6
*) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
*) Add a chunking filter to Apache. This brings us one step closer
to removing BUFF. [Ryan Bloom]
*) ap_add_filter now adds filters in a LIFO fashion. The first filter
added to the stack is the last filter to be called. [Ryan Bloom]
*) Apache 2.0 has been completely documented using Scandoc. The
docs can be generated by running 'make docs'. [Ryan Bloom]
*) Add filtered I/O to Apache. This is based on bucket brigades,
Currently the buckets still use BUFF under the covers, but that
should change quickly. The only currently written filter is the
core filter which just calls ap_bwrite. [The Apache Group]
*) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
built with thread support. [Jeff Trawick]
*) Abort configuration if --with-layout was specified and there's
no layout definition file. [Ken Coar]
*) Add support for '--with-port=n' option to configure. [Ken Coar]
*) Add support for extension methods for the Allow response header
field, and an API routine for accessing r->allowed and the
list of extension methods in a unified manner. [Ken Coar]
*) mod_cern_meta: fix broken file reading loop in scan_meta_file().
[Rob Simonson <simo@us.ibm.com>]
*) Get xlate builds working again. The apr renaming in 2.0a5 broke
APACHE_XLATE builds. [Jeff Trawick]
*) A configuration file parsing problem was fixed. When the
configuration file started with an IfModule/IfDefine container,
only the last statement in the container would be retained.
[Jeff Trawick]
Changes with Apache 2.0a5
*) Perchild is serving pages after passing them to different child
processes. There are still a lot of bugs, but this does work. I
have made requests against the same installation of Apache, and had
different servers use different user IDs to serve the responses.
This change moves to using socketpair instead of an AF_UNIX socket.
[Ryan Bloom]
*) Perchild MPM still doesn't work perfectly, but it is serving pages.
It can't seem to pass between child processes yet, but I think we
are closer now than before. This moves us back to using Unix
Domain Sockets. [Ryan Bloom]
*) libapr functions and types renamed with apr_ prefix.
#include "apr_compat.h" for 1.3.x backwards compat
[Perl]
*) Fix problems with APR sockaddr handling on Win32. It didn't always
return the right information on the local socket address.
[Gregory Nicholls <gnicholls@level8.com>]
*) ap_recv() on Win32: Set bytes-read to 0 on error.
[Gregory Nicholls <gnicholls@level8.com>]
*) Add an option to not detach from the controlling terminal without
going into single process mode. This allows for much easier
debugging of the process startup code. [Ryan Bloom]
*) ab: don't use perror() to report the failure of an APR function.
[Jeff Trawick]
*) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
scoreboard on graceful restarts.
[Ryan Bloom]
*) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
An invalid ap_proc_t was passed to ap_create_process().
[Jeff Trawick]
*) Allow modules to register filters. Those filters are still
never called, but this is a step in the right direction.
[Ryan Bloom and Greg Stein]
*) Register the mod_cgid daemon process for cleanup so that it is
killed at termination if it does not die when the parent gets
SIGTERM. This change is to fix occasional problems where the
process stays around. Bugs in similar logic in mod_rewrite and
mod_include were also fixed. [Jeff Trawick]
*) Fix a bug in the time handling. Basically, we were imploding a time
in ap_parseHTTPdate, but it had bogus data in the exploded time format.
Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
uses those two fields to adjust the time value. Because of the HTTP
spec, both of those values can be zero'ed out safely. This fixes
the bug correctly. [Ryan Bloom]
*) Fix a couple of place in the Windows code where the wrong error
code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
*) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
*) Added the APR_EOL_STR macro for platform dependent differences in
logfiles and other raw text (such as all APR files). Fixes logfiles
not terminated with cr/lf sequences in Win32. [William Rowe]
*) Move all strings functions in APR to src/lib/apr/strings and create
apr_strings.h for the prototypes. [Ryan Bloom]
*) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
to repeat the syscall until we stop getting EINTR. I noticed a
related problem at termination (SIGTERM) on FreeBSD when using
fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
implementation work properly with child init. Previously, ap_lock()
was essentially a no-op because all children were using different
locks and thus nobody ever blocked. [Jeff Trawick]
*) The htdocs/ tree has been moved out of the CVS source tree into
a separate area for easier development. This has NO EFFECT on
end-users or Apache installations. [Ken Coar]
*) Integrate the mod_dav module for WebDAV protocol handling. This
adds the dav and dav_fs modules, the SDBM library, and additional
XML handling utilities. [Greg Stein]
*) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
[Greg Stein]
*) Update the lib/expat-lite/ library (bring forward changes from
the Apache 1.3 repository). [Greg Stein]
*) If sizeof(long long) == sizeof(long), then prefer long in APR
configure.in. [Dave Hill <ddhill@zk3.dec.com>]
*) Add ap_sendfile for Tru64 Unix. Also, add an error message for
machines where sendfile is detected, but nobody has written ap_sendfile.
[Dave Hill <ddhill@zk3.dec.com>]
*) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
*) ab would start up more connections than needed, then quit when the
desired number were finished. Also fixed a logic error involving
ab keepalives. [Victor J. Orlikowski]
*) WinNT: Implement non-blocking pipes with timeouts to communicate
with CGIs. Apache 2.0a4 had non-blocking pipes but without
timeouts (i.e, if a timeout was specified, the pipe reverted to
a full blocking pipe). Now the behaviour is more in line with
Unix non-blocking pipes.
[Bill Stoddard]
*) WinNT: Implement accept socket reuse. Using mod_file_cache to
cache open file handles along with accept socket reuse enables
Apache 2.0 to serve non-keepalive requests for static files at
3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
and Apache 2.0 will serve almost 1200 rps on my system).
[Bill Stoddard]
*) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
supports two config directives, mmapfile (same behavious as
mod_mmap_static) and cachefile. Use the cachefile directive
to cache open file handles. This directive only works on systems
that have implemented the ap_sendfile API. cachefile works today
on Windows NT, but has not been tested on any flavors of Unix.
[Bill Stoddard]
*) Cleanup the configuration. With the last few changes the
configuration process automatically:
inherits information about how to build from APR. Allowing
APR to inform Apache that it should or should not use -ldl
Detects which mod_cgi should be used mod_cgi or mod_cgid,
based on the threading model
Apache calls APR's configure process before finishing it's
configuration processing, allowing for more information flow
between the two.
[Ryan Bloom]
*) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
with non-zero argument makes the socket non-blocking. BeOS and
OS/2 already worked this way. [Jeff Trawick]
*) ap_close() now calls ap_flush() for buffered files, so write
operations work a whole lot better on buffered files.
[Jeff Trawick]
*) Fix error messages issued from MPMs which explain where to change
compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
[Greg Ames]
*) ap_create_pipe() now leaves pipes in blocking state. (This helps
reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
now the way that the blocking state of a pipe is manipulated.
ap_block_pipe() is gone. [Jeff Trawick]
*) Correct the problem where the only local host name that the IP stack
can discover are 'undotted' private names. If no fully qualified
domain name can be identified, the default ServerName will be set to
the machine's IP address string. A warning is always provided if the
ServerName not specified, but assumed. Solves PR6215 [William Rowe]
*) Repair problems with config file processing which caused segfault
at init when virtual hosts were defined and which caused ServerName to
be ignored when there was no valid DNS setup. [Jeff Trawick]
*) Removed pointless ap_is_aborted macro function. [Roy Fielding]
*) Add ap_sendfile implementation for AIX
[Victor J. Orlikowski]
*) Repair C++ compatibility in ap_config.h, apr_file_io.h,
apr_network_io.h, and apr_thread_proc.h.
[Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
*) Bring the allocation and pool debugging code back into a working
state. This will need to be tested as so far it's only been used on
BeOS. [David Reid]
*) Change configuration command setup to be properly typesafe when in
maintainer mode. Note that this requires a compiler that can initialise
unions. [Ben Laurie]
*) Turn on buffering for config file reads. Part of this was to
repair buffered I/O support in Unix and implement buffered
ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
*) Win32: Fix problem where UTC offset was not being set correctly
in the access log. Problem reported on news group by Jerry Baker.
[Bill Stoddard]
*) Fix segfault when reporting this type of syntax error:
"</container> without matching <container> section", where
container is VirtualHost or Directory or whatever.
[Jeff Trawick]
*) Prevent the source code for CGIs from being revealed when using
mod_vhost_alias and the CGI directory is under the document root
and a user makes a request like http://www.example.com//cgi-bin/cgi
as reported in <news:960999105.344321@ernani.logica.co.uk>
[Tony Finch]
*) Add support for the new Beos NetwOrking Environment (BONE)
[David Reid]
*) xlate: ap_xlate_conv_buffer() now tells the caller when the
final input char is incomplete; ap_bwrite_xlate() now handles
incomplete final input chars. [Jeff Trawick]
*) Yet another update to saferead/halfduplex stuff -- need to ensure
that a bhalfduplex call occurs before logging or else DNS and
such can delay the last packet of the response. [Dean Gaudet]
*) Some syscall reduction in APR on unix -- don't seek when setting
up an mmap; and don't fcntl() more than once per socket.
[Dean Gaudet]
*) When mod_cgid is started as root, the cgi daemon now switches
to the configured User/Group (like other httpd processes)
instead of continuing as root. [Jeff Trawick]
*) The prefork MPM now uses an APR lock for the accept() mutex.
It has not been getting a lock at all recently. httpd -V now
displays APR's selection of the lock mechanism instead of the
symbols previously respected by prefork. [Jeff Trawick]
*) Change the mmap() feature test to check only for existence.
The previous check required features not used by Apache.
[Greg Ames]
*) Fix a couple of bugs in mod_cgid: The cgi arguments were
sometimes mangled. The len parm to accept() was not
initialized, leading sometimes to an endless loop of failed
accept() calls on OS/390 and anywhere else that failed the call
if the len was negative. Use <sys/un.h> for struct sockaddr_un
instead of declaring it ourselves to fix a compilation problem
on Solaris. [Jeff Trawick]
*) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
*) Fix zombie process problem with mod_cgi. [Jeff Trawick]
*) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
*) Fix storage overlay when loading dsos. Symptom: Apache dies at
initialization if ALLOC_DEBUG is defined; no known symptom
otherwise. [Jeff Trawick]
*) Fix typo in configure script when checking for mod_so. bash
doesn't seem to have a problem but /bin/sh on Solaris does.
Symptom: "./configure: test: unknown operator =="
[Jeff Trawick]
*) Rebind the Win32 NT and 9x services control into the MPM.
All console, WinNT SCM and Win9x pseudo-service control code is
now wrapped within the WinNT MPM.
[William Rowe]
*) Make a copy of getenv("PATH") before storing for later use. Some
getenv() implementations use the same storage for successive calls.
CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
*) Server Tokens work in 2.0 again. This also propogates the change
to allow just the product name in the server string using
PRODUCT_ONLY.
[Ryan Bloom]
Changes with Apache 2.0a4
*) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
won't need to call it. [Greg Ames, Jeff Trawick]
*) Move pre_config hook call to between configuration read and config
tree walk. This allows all modules to implement pre_config hooks
and know that they will be called at an appropriate time.
[Ryan Bloom]
*) mod_cgi, mod_cgid: Make ScriptLog directive work again.
[Jeff Trawick]
*) Add pre-config hooks back to all modules.
[Ryan Bloom]
*) Fix a SIGSEGV in ap_md5digest(), which is used when you have
ContentDigest enabled and we can't/don't mmap the file.
[Jeff Trawick]
*) We now report the correct line number for syntax errors in config
files. [Ryan Bloom, Greg Stein, Jeff Trawick]
*) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
related bugs, and changed shmem/locking to use apr API. Shared-mem
is currently disabled, however, because of problems with graceful
restarts. [Ronald Tschal<61>r]
*) Fix corruption of IFS variable in --with-module= handling.
Depending on the user's shell or customization thereof, there
would be errors generating ap_config_auto.h later in the configure
procedure. [Jeff Trawick]
*) mod_cgi: Restore logging of stderr from child process when ScriptLog
isn't used (as in 1.3), except that on Unix it is now logged via
ap_log_rerror() instead of by the child having STDERR_FILENO refer
to the error log. [Greg Ames, Jeff Trawick]
*) Add '-D' argument processing for run time configuration defines.
[William Rowe]
*) Organize http_main.c as independent code, such that no code or
global data is exported from it. WIN32 will dynamically link it
to the server core, so this will prevent mutual dependency.
[William Rowe]
*) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
and APR_VAR_EXPORT to correctly resolve apr functions and globals.
[William Rowe]
*) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
[William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
*) Add mod_charset_lite for configuring character set translation.
[Jeff Trawick]
*) Add '-n' option to htpasswd to make it print its user:pw record
on stdout rather than having to frob a text file. [Ken Coar]
*) Fix saferead. Basically, we flush the output buffer if a read on the
input will block.
[Ryan Bloom]
*) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
a conversion is single-byte only. [Jeff Trawick]
*) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
the BeOS 5.0 documentation says that shutdown doesn't work yet.
[Roy Fielding]
*) Fix some minor errors where pid was being manipulated as an int
instead of the portable pid_t. [Roy Fielding]
*) Fix some error log prints that were printing the pointer to a
structure rather than the pid within the structure.
[Jeff Trawick, Roy Fielding]
*) ab: Fix a command-line processing bug; track bad headers in
err_response; support reading headers up to 2K.
[Ask Bjoern Hansen <ask@valueclick.com>]
*) Fix ap_resolve_env() so that it handles new function added in a prior
alpha (see "Added the capability to do ${ENVVAR} constructs in the
config file.") as well as the constructs used by mod_rewrite.
[Paul Reder <rederpj@raleigh.ibm.com>]
*) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
*) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
APR to perform translation, instead of accessing the hard-coded tables
in 1.3's ebcdic.c. [Jeff Trawick]
*) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
[Jeff Trawick]
*) Add the ability to hook into the config file reading phase. Basically
if a directive is specified EXEC_ON_READ, then when that directive is
read from the config file, the assocaited function is executed. This
should only be used for those directives that must muck with HOW the
server INTERPRETS the config. This should not be used for directives
that re-order or replace items in the config tree. Those changes should
be made in the pre-config step.
[Ryan Bloom]
*) Add mod_example to the build system.
[Tony Finch]
*) APR: Add ap_xlate_conv_byte() to convert one char between single-
byte character sets. [Jeff Trawick]
*) Pick up various EBCDIC fixes from 1.3 (from Martin
Kraemer and Oliver Reh originally according to the change log).
[Jeff Trawick]
*) Fix a couple of problems in RFC1413 support (controlled by the
IdentityCheck directive). Apache did not build the request string
properly and more importantly Apache would loop forever if the
would-be ident server dropped the connection before sending a
properly terminated response. [Jeff Trawick]
*) apxs works in 2.0.
[Ryan Bloom]
*) Reliable piped logs work in 2.0.
[Ryan Bloom]
*) Introduce a hash table implementation into APR to be used for
replacing tables and other random data structures in Apache.
[Tony Finch]
*) Add some more error reporting to htpasswd in the case of problems
generating or accessing the temporary file. Also, pass in a
buffer if the implementation knows how to use it (i.e., if L_tmpnam
is defined). [Ken Coar]
*) Configure creates config.nice now containing your configure
options. Syntax: ./config.nice [--more-options]
[Sascha Schumann]
*) Fix various return code problems in APR on Win32. For most of
these, APR was returning APR_EEXIST instead of GetLastError()/
WSAGetLastError(). [Jeff Trawick]
*) Make piped logs work again in version 2.0
[Ryan Bloom]
*) Add VPATH support to UNIX build system of Apache and APR.
[Sascha Schumann]
*) Fix ap_tokenize_to_argv to respect the const arguments that are
passed to it.
[Ryan Bloom]
*) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
Patch submitted to author.
[Sascha Schumann]
*) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
/sbin in PATH on FreeBSD (all submitted to rse previously)
[Jeff Trawick]
*) Fix building Pthread-based MPMs on OpenBSD
[Sascha Schumann] PR#26
*) Fix ap_readdir() problem on systems where d_name[] field in
struct dirent is declared with only one byte. (This problem only
affected multithreaded builds.) This caused a segfault during
pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
least). [Jeff Trawick]
*) Fix some make-portability problems on at least Tru64, Irix
and UnixWare.
[Sascha Schumann] PR#18, PR#39
*) Add ap_sigwait() to support old-style sigwait() on systems
like OS/390 and UnixWare.
[Sascha Schumann]
*) Add POSIX-thread flags for more platforms.
[Sascha Schumann]
*) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
(on Unix, at least) to handle resolver errors. Fix a bug in
the definition of APR_ENOMEM so that ap_strerror() can spit
out the correct error message for it.
[Jeff Trawick]
Changes with Apache 2.0a3
*) mod_so reports ap_os_dso_error() if ap_dso_load() fails
[Doug MacEachern]
*) API: *HOOK* macros now have an AP_ prefix
[Doug MacEachern]
*) Win32: Eliminate redundant calls to initialize winsock.
[Tim Costello <timcostello@ozemail.com.au>]
*) Fix bugs initializing ungetchar for pipes.
[Chia-liang Kao <clkao@CirX.ORG>]
*) The ab program in the src/support directory is now portable using
APR.
[Ryan Bloom]
*) Support directory is being compiled when the server is built
[Ryan Bloom]
*) The configure option --with-program-name has been added to allow
developers to rename the executable at configure time. This also
changes the name of the config files to match the executable's name.
[Ryan Bloom]
*) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
containing version numbers. [Martin Pool]
*) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
Unix; access_log and error_log now created with these perms; non-
Unix is unaffected [Jeff Trawick]
*) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
Replaced more magic numbers with MD5_DIGESTSIZE.
[William Rowe, Roy Fielding]
*) Win32: Get mod_auth_digest compiling and added to the Windows
build environment. Not tested and I'd be suprised if it
actually works. [Bill Stoddard]
*) Revamp the Win32 make environment. Makefiles have been removed and
Apache.dsw created to bring together all the pieces. Create new file
os/win32/BaseAddr.ref to define module base addresses (to prevent
dll relocation at start-up).
[William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
*) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
of the \015, \012, and \015\012 constants with macros.
[Greg Ames <gregames@us.ibm.com>]
*) Add ap_xlate_open() et al for translation of text between different
character sets. The initial implementation requires iconv().
[Jeff Trawick]
*) More FAQs and answers from comp.infosystems.www.servers.unix.
[Joshua Slive <slive@finance.commerce.ubc.ca>]
*) CGI output is being timed out now.
[Ryan Bloom]
*) Fix the problem with dieing quietly. dupfile now takes a pool which
is used by the new apr file. There is no reason to create a new file
with the same lifetime as the original file.
[Ryan Bloom]
*) Win32: Attempt to eliminate dll relocation at start-up by specifying
module base addresses. This will help shooting seg faults
in the field. [William Rowe <wrowe@lnd.com>]
*) Update Apache on Windows documentation. Add new document
describing how to compile Apache on Windows.
[William Rowe <wrowe@lnd.com>]
*) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
microseconds instead of seconds. Some storage leaks and other
minor bugs in related code were fixed. [Jeff Trawick]
*) Win32: First cut at getting mod_isapi working under 2.0
[William Rowe <wrowe@lnd.com>]
*) First stab at getting mod_auth_digest working under 2.0
quick change summary:
- moved the random byte generation (ap_generate_random_bytes) into APR
- now uses ap_time_t
- compiles and runs on linux
- tested with amaya
[Brian Martin <bmartin@penguincomputing.com>]
*) Win32: Move the space stripping of physical service names
fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
unresolved symbol. Add dependency checking to the
CreateService call to ensure TCPIP and AFP (winsock) is started
before Apache.
[William Rowe <wrowe@lnd.com>]
*) Win32: Add code to perform latebinding on functions that may
not exist on all levels of Windows where Apache runs. This
is needed to allow Apache to start-up on Win95/98. All calls
to non portable functions should be protected with
ap_oslevel checks to prevent runtime segfaults.
[William Rowe <wrowe@lnd.com>]
*) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
*) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
*) Win32: Get non-blocking CGI pipe reads working under Windows NT.
This addresses PR 1623. Still need to address timing out runaway
CGI scripts. [Bill Stoddard]
*) Win32: Make ap_stat Windows 95/98 friendly
[William Rowe <wrowe@lnd.com>]
*) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
always fail. Need to initialise the dwOSVersionInfoSize member of the
OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
always fails.
The patch also enhances ap_get_oslevel (and the associated enum) to
handle selected service packs for NT4, and adds recognition for
Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
we can use ReadFileScatter and WriteFileGather in readwrite.c.
[Tim Costello <Tim.Costello@BTFinancialgroup.com>]
*) Get mod_rewrite building and running, and mod_status building for Win NT
[Allan Edwards <ake@raleigh.ibm.com>]
*) Patch to port mod_auth_db to the 2.0 api and also to support
Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
2.7.7. It should work with version 1 as well but I haven't tested it.
[Brian Martin <bmartin@penguincomputing.com>]
*) Get APR DSO code working under Windows. Includes cross platform
fixes to mod_so.c.
[Tim.Costello@BTFinancialgroup.com]
*) Fix some of the Windows APR time functions.
[William Rowe]
*) FAQ changes related to tidying up historical documents on the web site.
[Joshua Slive <slive@finance.commerce.ubc.ca>]
*) Move Windows DSO code into APR.
[Bill Stoddard]
*) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
at build time. At this point, the server will not compile on Windows because
of the recent DSO commits. Fixing those next.
[Bill Rowe & Bill Stoddard]
*) Added error checking for file I/O APR routines.
[Jon Travis <jtravis@covalent.net>]
*) APR: Don't use the values of resolver error codes for the
corresponding APR error codes. On Unix and Win32, return the
proper APR error code after a resolver error. [Jeff Trawick]
Changes with Apache 2.0a2
*) Renamed the executable back to httpd on all platforms other
than Win32
[Ryan Bloom]
*) Allow BeOS to survive restarts, log properly and a few
small things it had problems with due to the way it setup
users and groups. [David Reid]
*) Get mod_rewrite working with APR locks
[Paul Reder <rederpj@raleigh.ibm.com>]
*) Actually remove the sempahore when the lock cleanup routine
is called on BeOS. [David Reid]
*) Clear hook registrations between reads of the config file.
When DSOs are unloaded and re-loaded the old hook pointers may
no longer be valid. This fix eliminates potential segfaults.
[Allan Edwards <ake@raleigh.ibm.com>]
*) Fix a problem with Sigfunc not being defined or bypassed
if sigaction() wasn't found. [Jim Jagielski]
*) Fix the locking mechanism on BSD variants. They now use fcntl
locks. This allows the server to start and serve pages.
[Ryan Bloom]
*) First cut at getting the Win32 installer to work
[William Rowe <wrowe@lnd.com>]
*) Get htpasswd compiling under Windows
[William Rowe <wrowe@lnd.com>]
*) Change the log message for a bind() failure to show the
interface and port number. [Jeff Trawick]
*) Import the documentation from 1.3.12 and bring parts of it
up-to-date with respect to the changes that have occurred
in 2.0.
[Tony Finch]
*) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
now logged correctly on BeOS.
[David Reid]
*) Create one makefile for all Win32 distributions (NT/2000/95/98).
Makefile.win includes the same user interface as the old
Makefile.nt
[William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
*) Win32 exec now uses COMSPEC environment string for command
shell path resolution.
[William Rowe <wrowe@lnd.com>] PR#3715
*) Win32: ap_connect() was not returning correct error condition
PR5866
[Allen Prescott <allen@clanprescott.com>]
*) Win32: ap_open() was broken on Win9x because an NT-specific
flag was passed to CreateFile. ap_puts() added an unnecessary
'\n'.
[Jeff Trawick <trawick@us.ibm.com>]
*) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
confusing ee/et name and made all extensions language/dialect
rather than country reflecting. Changed example files to
explicit reflect the ISO charset and added a few common
ones to the example config [dirkx]
*) Extend external module capability. To use this, you call
configure with --with-module=path/to/mod1,path/to/mod2,etc.
[Ryan Bloom]
*) Backported the various "default charset" fixes from 1.3.12,
including the AddDefaultCharset directive. [Jim Jagielski]
*) Added the capability to do ${ENVVAR} constructs in the
config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
it does this on a line by line basis; i.e. if the envvar
expands to something with spaces you have to protect it
by adding quotes around it (Unless of course you expect it
to contains more than one argument. Alternatively you
can compile it on a per token basis; which is what people
usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
hampers fancier hacks.
[Dirk-Willem van Gulik]
*) Changed the 'ErrorDocument' syntax in that it NO longer
supports the asymetric
ErrorDocument 301 "Some message
Note the opening " quote, without a closing quote. It now
has either the following syntaxes
ErrorDocument XXX /local/uri
ErrorDocument XXX http://valid/url
ErrorDocument XXX "Some Message"
The recognition heuristic is: if it has a space it
is a message. If it has no spaces and starts with a /
or is a valid URL then treat it that way. Otherwise it
is assumed to be a message.
This breaks backward compatibility but makes live a hell
of a lot easier for GUI's and config file parsers.
[Dirk-Willem van Gulik]
*) Changed 'CacheNegotiatedDocs' from its present/not-present
syntax into a 'on' or 'off' syntax. As it currently is the
only non nesting token which uses NO_ARGS and thus is an
absolute pain for any config interface automation. This
breaks backward compatibility. [Dirk-Willem van Gulik]
*) Add ability to add external modules to the build process. This is
done with --with-module=/path/to/module. Modules can only be added
as static modules at this point.
[Ryan Bloom]
Changes with Apache 2.0a1
*) Fix FreeBSD 3.3 core dump.
Basically, ap_initialize() needs to get called before
create_process(), since create_process() passes op_on structure
to semop() to get a lock, but op_on isn't initialized until
ap_initialize() calls setup_lock(). Here is a slight
rearrangement to main() which calls ap_initialize() earlier...
[Jeff Trawick <trawick@us.ibm.com>]
*) Enable Apache to use sendfile/TransmitFile API
[Bill Stoddard, David Reid, Paul Reder]
*) Re-Implement Win32 APR network I/O APIs and most of the file I/O
APIs.
[Bill Stoddard]
*) Make file I/O and network I/O writev/sendv APIs consistent.
Eliminate use of ap_iovec_t and use Posix struct iovec.
Use seperate variable on ap_writev to set the number of iovecs
passed in and number of bytes written.
[Bill Stoddard]
*) Adapt file iol to use APR functions. Replaced ap_open_file()
with ap_create_file_iol(). ap_create_file_iol() requires that
the file be opened prior to the call using ap_open().
[Bill Stoddard]
*) Port mod_include and mod_cgi to 2.0
[Paul Reder, Bill Stoddard]
*) ap_send{,v}, ap_recv, ap_sendfile API clarification --
bytes_read/bytes_written is always valid (never -1). Plus
some fixes to buff.c to correct problems introduced by the
errno => ap_status_t changes a while back. Plus a fix to
chunked encoding introduced right at the beginning of 2.0.
[Dean Gaudet]
*) Revamped UNIX build system to use autoconf and libtool.
[Manoj Kasichainula, Sascha Schumann]
*) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
*) More rigorous checking of Host: headers to fix security problems
with mass name-based virtual hosting (whether using mod_rewrite
or mod_vhost_alias).
[Ben Hyde, Tony Finch]
*) Add back support for UseCanonicalName in <Directory> containers.
[Manoj Kasichainula]
*) Added APLOG_STARTUP log type. This allows us to write an error
message without any of the date and time information. As a part
of this change, I also removed all of the calls to fprintf(stderr
and replaced them with calls to ap_log_error using APLOG_STARTUP
writing to stderr is no longer portable, because we don't direct
stderr to the error log on all platforms.
[Ryan Bloom]
*) Convert error logging functions to take errno as an argument.
This makes our error logs more portable, because some Windows API's
don't set errno. This change allows us to still output a valid
message on all of our platforms.
[Ryan Bloom]
*) mod_mime_magic runs in 2.0-dev now.
[Paul Reder <rederpj@raleigh.ibm.com>]
*) sendfile has been added to APR.
[John Zedlewski <zedlwski@Princeton.EDU>]
*) buff.c has been converted to no longer use errno.
[Manoj Kasichainula]
*) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
interface adaption to APR functions did it. [Martin Kraemer]
*) Support DSOs properly on 32-bit HP-UX 11.0
[Dilip Khandekar <dilip@cup.hp.com>]
*) Updated MM in APR source tree from version 1.0.8 to 1.0.11
[Ralf S. Engelschall]
*) Cleaned APR build environment integration and bootstrap APR
automatically for developers from src/Configure.
[Ralf S. Engelschall]
*) Fixed building of src/support/htpasswd.c
[Ralf S. Engelschall]
*) When generating the Location: header, mod_speling forgot
to escape the spelling-fixed uri. (Forw-Port from 1.3)
[Martin Kraemer]
*) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
*) Change all pools to APR contexts. This is the first step to
incorporating APR into Apache. [Ryan Bloom]
*) Move "handler not found" warning message to below the check
for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
*) Support line-continuation feature in config.option file and
allow the loading of multiple option sections at once via
``--with-option=<section1>,<section2>,...''
[Ralf S. Engelschall]
*) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
Changes with Apache MPM
*) Use asynchronous AcceptEx() and a completion port to accept and
dispatch connections to threads in Windows NT/2000.
[Bill Stoddard]
*) Implement WINNT Win32 MPM from original Win32 code in http_main.c
[Bill Stoddard]
*) Implement the APACI --with-option facility
(per default used the config.option file).
[Ralf S. Engelschall]
*) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
*) Start to implement module-defined hooks that are a) fast and b) typesafe.
Replace pre_connection module call with a register_hook call and
implement pre_connection as a hook. The intent is that these hooks will
be extended to allow Apache to be multi-protocol, and also to allow the
calling order to be specified on a per-hook/per-module basis.
[Ben Laurie]
*) Implement mpm_* methods as "modules". Each method gets its own
subdir in src/modules (eg: src/modules/prefork). Selection
of method uses Rule MPM_METHOD. [Jim Jagielski]
*) Port the hybrid server from the apache-apr repository as
mpm_mpmt_pthread. [Manoj Kasichainula]
*) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
amongst the unix MPMs.
*) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
signal handling for the new world order. [Dean Gaudet]
*) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
of alloc.c for now. [Dean Gaudet]
*) Handle partial large writes correctly. [Ben Laurie]
*) Eliminate conn_rec's pointer to server. All it knows is the base server
based on IP/port. [Ben Laurie]
*) Port a bunch of modules to the new module structure.
["Michael H. Voase" <mvoase@midcoast.com.au>]
*) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
*) Basic restructuring to introduce the MPM concept; includes various
changes to the module API... better described by
docs/initial_blurb.txt. [Dean Gaudet]
Changes with Apache pthreads
*) New buff option added: BO_TIMEOUT. It describes the timeout for
buff operations (generally over a network).
[Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
*) Created http_accept abstraction. Added 4 new functions (not exported):
init_accept(), begin_accepting_requests(), get_request(),
stop_accepting_requests() [Bill Stoddard]
*) Fix to ap_rprintf call that allows mod_info to work properly.
[James Morris <jmorris@intercode.com.au>]
*) user and ap_auth_type fields were moved from connection_rec to
request_rec. [Ryan Bloom]
*) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
needed in a threaded server.
*) Initial pthread implementation from from Dean's apache-nspr code.
[Bill Stoddard, Ryan Bloom]
Changes with Apache 1.3.9
*) Remove bogus error message when a redirect doesn't set Location.
Instead, use an empty string to avoid coredump if the error message
was supposed to include a location. [Roy Fielding]
*) Don't allow configure to include mod_auth_digest unless it is
explicitly requested, even if the user asked for all modules.
[Roy Fielding]
*) Translate module names to dll names for OS/2 so that they are no more
than 8 characters long and have an extension of "dll" instead of "so".
[Brian Havard]
*) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
Fix test-compile check to check for randbyte instead of trand32.
Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
and tweak to make Amaya happier. [Ronald Tschal<61>r]
*) Ensure that the installed expat include files are world readable,
just like the other header files. [Martin Kraemer]
*) Fixed generated AddModule adjustments in APACI's `configure' script
in order to allow (new) modules like mod_vhost_alias to be handled
correctly (which was touched by the adjustments for mod_alias).
[Ralf S. Engelschall]
*) For binary builds, add -R flag to apachectl to work around the lack of
an absolute path to the ./libexec directory where the libhttp.ep file
is needed for SHARED_CORE architectures. [Randy Terbush]
*) WIN32: Create the CGI script process as DETACHED. This may solve the
problem observed by some Win95/98 users where they get CGI script
output sent to the console. [Bill Stoddard]
*) Fix (re)naming in the uuencode/decode section. The ap/ap_
routines are now called ap_base64* and are 'plain' (i.e., no
pool access or anything clever). Inside util.c the routines acting
like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
The oddly named ap_uuencode(), ap_uudecode() are kept around for
now but deprecated. [dirkx]
*) Clean up the base64 and SHA1 additions and make sure they are
represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
files. [Roy Fielding]
*) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
checking. Allow compiling on VS 6.0. [Randy Terbush]
*) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
*) Use TestCompile to search for the truerand library (rather than blindly
assuming its existence). If it is not found, complain (but do not
exit - yet). [Martin Kraemer]
*) We forgot to add the new exported function names to
src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
*) Add description of -T command-line option to usage().
[Ralf S. Engelschall]
*) For "some" platforms (notably, EBCDIC based ones), libos needs to be
searched only AFTER libap has been searched, because libap needs
some symbols from libos. [Martin Kraemer]
*) Fix conflict with original mod_digest related to the symbol of the
module dispatch list (which has to be unique for DSO and follow the
usual conventions for the installation procedure).
[Ralf S. Engelschall]
*) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
for other platforms as well. [Martin Kraemer]
*) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
types by AP_LONG and replace reference to renamed variable 'ubuf'
by 'buffer'. [Martin Kraemer]
Changes with Apache 1.3.8 [not released]
*) Flush the output buffer immediately after sending an error or redirect
response, since the result may be needed by the client to abort a
long data transfer or restart a series of pipelined requests.
[Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
*) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
[Ian Turner <iant@sequent.com>] PR#4735
*) Local struct mmap in http_core.c conflicted with system structure
name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
*) Added updated mod_digest as modules/experimental/mod_auth_digest.
[Ronald Tschal<61>r <ronald@innovation.ch>]
*) Fix a memory leak where the module counts were getting messed
up across restarts. [David Harris <dharris@drh.net>]
*) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
properly in mod_access.
["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
*) RewriteLock/RewriteMap didn't work properly with virtual hosts.
[Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
*) PORT: Support for compaq/tandem/com.
[Michael Ottati <michael.ottati@compaq.com>, dirkx]
*) Added SHA1 password encryption support to easy migration from
Netscape servers. See support/SHA1 for more information.
Caused the separation of ap_md5.c into md5, sha1 and a general
ap_checkpass.c with just a validate_passwd routine. Added a
couple of flags to support/htpasswd. Some reuse of the to64()
function; hence renamed to ap_to64().
[Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
*) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
with ASCII/EBCDIC conversions in "ident" query.
[David McCreedy <McCreedy@us.ibm.com>]
*) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
Change "Power Macintosh" to Power* so if uname prints "Power Book"
we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
*) Fix SIGSEGV on some systems because the Vary fix below included
a call to table_do with a variable argument list that was not
NULL terminated. Replaced with better implementation. [Roy Fielding]
Changes with Apache 1.3.7 [not released]
*) The "Vary" response header field is now sanitised right before
the header is sent back to the client. Multiple "Vary" fields
are combined, and duplicate tokens (e.g., "Vary: host, host" or
"Vary: host, negotiate, host, accept-language") are reduced to
single instances. This is a better solution than the force-no-vary
one (which is still valid for clients that can't cope with Vary
at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
*) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
*) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
least on Linux and FreeBSD for now.
[Rasmus Lerdorf]
*) Win32: More apache -k restart work. Restarts are now honored
immediately and connections in the listen queue are -not- lost.
This is made possible by the use of the WSADuplicateSocket()
call. The listeners are opened in the parent, duplicated, then
the duplicates are passed to the child. The original listen sockets
are not closed by the parent across a restart, thus the listen queue
is preserved.
[Bill Stoddard <stoddard@raleigh.ibm.com>]
*) Fix handling of case when a client has sent "Expect: 100-continue"
and we are going to respond with an error, but get stuck waiting to
discard the body in the pointless hope of preserving the connection.
[Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
*) Fix 'configure' to work correctly with SysV-based versions of
'tr' (consistent with Configure's use as well). [Jim Jagielski]
*) apxs: Add "-S var=val" option which allows for override of CFG_*
built-in values. Add "-e" option which works like -i but doesn't
install the DSO; useful for editing httpd.conf with apxs. Fix
editing code so that multiple invocations of apxs -a will not
create duplicate LoadModule/AddModule entries; apxs can now be
used to re- enable/disable a module. [Wilfredo Sanchez]
*) Win32: Update the server to use Winsock 2. Specifically, link with
ws2_32.lib rather than wsock32.lib. This gives us access to
WSADuplcateSocket() in addition to some other enhanced comm APIs.
Win 95 users may need to update their TCP/IP stack to pick up
Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
[Bill Stoddard stoddard@raleigh.ibm.com]
*) Win32: Redirect CGI script stderr (script debug info) into the
error.log when CGI scripts fail. This makes Apache on Win32
behave more like Unix.
[Bill Stoddard stoddard@raleigh.ibm.com]
*) Fixed `httpd' usage display: -D was missing.
[Ralf S. Engelschall] PR#4614
*) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
[Ralf S. Engelschall] PR#4561, PR#4562
*) OS/2: Fix problem with accept lock semaphores where server would die with
"OS2SEM: Error 105 getting accept lock. Exiting!"
[Brian Havard] PR#4505
*) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
[Randy Terbush <randy@covalent.net>]
*) Add the new mass-vhost module (mod_vhost_alias.c) developed and
used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
*) Better GCC detection for DSO flags under Solaris 2 where the `cc'
command potentially _is_ GCC. [Ralf S. Engelschall]
*) Fix apxs build issues on AIX
[Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
*) DocumentRoot Checking: Under previous versions, when Apache
first started up, it used to do a stat of each DocumentRoot to
see if it existed and was a directory. If not, then an error
message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
does not exist, you will get error messages in error_log. If
the '-t' command line option is used (to check the configuration)
the check of DocumentRoot IS performed. An additional command
line option, '-T', has been added if you want to avoid the
DocumentRoot check even when checking the configuration.
[Jim Jagielski]
*) Win32: The query switch "apache -S" didn't exit after showing the
vhost settings. That was inconsistent with the other query functions.
[Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
*) Win32: Changed behaviour of apache -k restart.
Previously, the server would drain all connections in the stack's
listen queue before honoring the restart. On a busy server, this
could take hours. Now, a restart is honored almost immediately.
All connections in Apache's queues are handled but connections in
the stack's listen queue are discarded. Restart triggered by
MaxRequestPerChild is unchanged.
[Bill Stoddard <stoddard@raleigh.ibm.com>]
*) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
the accept loop. Good for a 5% performance boost. Cleaned up
parent/child process management code.
[Bill Stoddard <stoddard@raleigh.ibm.com>]
*) Added ceiling on file size for memory mapped files.
[John Giannandrea <jg@meer.net>] PR#4122
*) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
[Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
*) Determine AP_BYTE_ORDER for ap_config_auto.h and already
use this at least for Expat. [Ralf S. Engelschall]
*) Allow .module files to specify libraries with Lib:.
[Ben Laurie]
*) Allow SetEnvIf[NoCase] to test environment variables as well
as header fields and request attributes. [Ken Coar]
*) Fix mod_autoindex's handling of ScanHTMLTitles when file
content-types are "text/html;parameters". PR#4524 [Ken Coar]
*) Remove "mxb" support from mod_negotiation -- it was a draft feature
never accepted into any standard, and it opens up certain DoS
attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
*) TestCompile updated. We can now run programs and output the
results during the Configure process. [ Jim Jagielski]
*) The source is now quad (long long) aware as needed. Specifically,
the Configure process determines the correct size of off_t and
*void. When the OS/platform/compiler supports quads, ap_snprintf()
provides for the 'q' format qualifier (if quads are not available,
'q' is silently "demoted" to long). [Jim Jagielski]
*) When the username or password fed to htpasswd is too long, include the
size limit in the error message. Also report illegal characters
(currently only ':') in the username. Add the size restrictions
to the man page. [Ken Coar]
*) Fixed the configure --without-support option so it doesn't result in
an infinite loop. [Marc Slemko]
*) Piped error logs could cause a segfault if an error occured
during configuration after a restart.
[Aidan Cully <aidan@panix.com>] PR#4456
*) If a "Location" field was stored in r->err_headers_out rather
than r->headers_out, redirect processing wouldn't find it and
the server would core dump on ap_escape_html(NULL). Check both
tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
if Location isn't set. [Doug MacEachern, Ken Coar]
*) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
of the Expat 1.0.2 distribution. [Greg Stein]
*) Replace regexec() calls with calls to a new API stub function
ap_regexec(). This solves problems with DSO modules which use the regex
library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
*) Add 'Request_Protocol' special keyword to mod_setenvif so that
environment variables can be set according to the protocol version
(e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
*) Add DSO support for OpenStep (Mach 4.2) platform.
[Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
*) Fix sed regex for generating ap_config_auto.h in src/Configure.
[Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
*) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
*) Better DSO flags recognition on NetBSD platforms using ELF.
[Todd Vierling <tv@pobox.com>] PR#4310
*) Always log months in english format for %t in mod_log_config.
[Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
*) Support for server-parsed and multiview-determined ReadmeName and
HeaderName files in mod_autoindex. Removed the restriction on
"/"s in ReadmeName and HeaderName directives since the *sub_req*
routines will deal with the access issues. (It's now possible to
have {site|group|project|customer|...} wide readmes and headers.)
[Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,

*) Fix configuration engine re-entrant hangups, which solve a
handful of problems seen with mod_perl <Perl> configuration sections
[Salvador Ortiz Garcia <sog@msg.com.mx>]
*) Mac OS and Mac OS X Server now use the appropriate custom layout
by default when building with APACI; allow for platform-specific
variable defaults in configure. [Wilfredo Sanchez]
*) Do setgid() before initgroups() in http_main; some platforms
zap the grouplist when setgid() is called. This was fixed in
suexec earlier, but the main httpd code missed the change.
[Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2579

*) OS/2: Add support for building loadable modules using DLLs.
[Brian Havard]
*) Add iconsdir, htdocsdir, and cgidir to config.layout.
[Wilfredo Sanchez]
*) Fix minor but annoying bug with the test for Configuration.tmpl
being newer than Configuration so that it is less likely to fail
when using APACI and shadow sources. [Wilfredo Sanchez]
*) PORT: Add initial support for Mac OS (versions 10.0 and
greater). Use Mac OS X Server layout for now. Clean up dyld code
in unix/os.c, and don't install the dyld error handlers, which
are no longer needed in Mac OS. [Wilfredo Sanchez]
*) Rename Rhapsody layout to "Mac OS X Server". Change install
locations to appropriate ones for user-built (as opposed to
system) installs. [Wilfredo Sanchez]
*) Modify mod_autoindex's handling of AddDescription so that the
behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
*) Add functionality to the install-bindist.sh script created by
binbuild.sh to use tar when copying distribution files to the
serverroot. This allows upgrading an existing installation
without nesting the new distribution in the old.
install-bindist.sh now detects the local perl5 path to install
apxs and dbmmanage with proper path to perl interpreter.
Add an install-binsupport target which copies the source files
for apxs and dbmmanage to bindist to allow these scripts to
be properly installed relative to the destination serverroot.
[Randy Terbush, Covalent Technologies, randy@covalent.net]

*) Correct an apparent typo: on the Windows and MPE platforms, the
htpasswd utility was limiting passwords to only 8 characters.
[Ken Coar]
*) EBCDIC platforms: David submitted patches for two bugs in the
MD5 digest port for EBCDIC machines:
a) the htdigest utility overwrote the old contents of the digest file
b) the Content-MD5 header value (ContentDigest directive) was wrong
when the returned file was not converted from EBCDIC, but was a
binary (e.g., image file) in the first place.
[David McCreedy <mccreedy@us.ibm.com>]
*) support/htpasswd now permits the password to be specified on the
command line with the '-b' switch. This is useful when passwords
need to be maintained by scripts -- particularly in the Win32
environment. [Ken Coar]
*) Win32: Win32 multiple services patch. Added capability to install and
run multiple copies of apache as individual services.
Example 1:
apache -n apache1 -i -f c:/httpd.conf
Installs apache as service 'apache1' and associates c:/httpd.conf
with that service.
net start apache1
Starts apache1 service.
net stop apache1
Stops apache1 service
Example 2:
apache -n apache2 -i
Installs apache as service 'apache2'. httpd.conf is located under
the default server root (/apache/conf/httpd.conf).
net start apache2
Starts apache2 service.
Example 3:
apache -n apache3 -i -d c:/program files/apache
Install apache as service 'apache3' and sets server root to
c:/program files/apache.
Example 4:
apache -n apache2 -k restart
Restart apache2 service
[Keith Wannamaker, Ken Parzygnat, Bill Stoddard]
*) Correct the signed/unsigned character handling for the MD5 routines;
mismatches were causing compilation problems with gcc -pedantic and
in the TPF cross-compilation. [Ken Coar]
*) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
a roughly 5 fold speed up. [Brian Havard]
*) proxy ftp: instead of using the hardwired string "text/plain" as
a fallback type for files served by the ftp proxy, use the
ap_default_type() function to determine the configured type.
This allows for special configurations like
<Directory proxy:ftp://some.host>
DefaultType gargle/blurb
</Directory>
Additionally, add the Content-Encoding: header to FTP proxy replies
when the encoding is defined (by the AddEncoding directive).
Because it was missing, it was almost impossible to browse compressed
files using the FTP proxy (works now perfectly in Communicator).
The ftp proxy now also returns the Date: and Server: header lines (if not
much else... This code is "somewhat" broken) like normal requests do.
[Martin Kraemer]
*) Be more smart in APACI's configure script when determining the UID/GID

*) In configure, do not append the target name to the directory path if

*) SIGPIPE is now ignored by the server core. The request write routines
(ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
correctly check for output errors and mark the connection as aborted.
Replaced many direct (unchecked) calls to ap_b* routines with the
analogous ap_r* calls. [Roy Fielding]
*) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
DBM format mapfiles now uses a 4-way hash table with LRU functionality.
Furthermore map lookups for non-existent keys are now cached as well.
Additionally "txt" maps are now parsed with simple string functions
instead of using ap_pregcomp(). As a side effect a bug that prevented
the usage of keys containing the "," character was fixed.
The changes drastically improve the performance when large rewrite maps
are in use.
[Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160

*) Win32: The filename validity checker now allows filenames containing
characters in the range 0x80 to 0xff (for example accented characters).
[Paul Sutton] PR#3890
*) Added conditional logging based upon environment variables to
mod_log_config. mod_log_referer and mod_log_agent

*) Allow apache acting as a proxy server to relay the real
reason of a failure to a client rather than the "internal
server error" it does currently. The general exposure mechanism
can be triggered by any module by setting the "verbose-error-to"
note to "*"; this allows more than just proxy errors to be exposed.
[Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
*) Moved man pages for ab and apachectrl to section 8.
[Wilfredo Sanchez, Roy Fielding]
*) Added -S option to install.sh so that options can be passed to
strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
*) Tweak modules Makefile generated by Configure so that it handles
the test case of no modules being selected. [chaz@reliant.com]
*) Added a <LimitExcept method ...> sectioning directive that allows
the user to assign authentication control to any HTTP method that
is *not* given in the argument list; i.e., the logical negation
of the <Limit> directive. This is particularly useful for controlling
access on methods unknown to the Apache core, but perhaps known by
some module or CGI script. [Roy Fielding, Tony Finch]
*) Prevent apachectl from complaining if the PIDFILE exists but
does not contain a process id, as might occur if the server is
being rapidly restarted. [Wilfredo Sanchez]
*) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
*) Entity tag comparisons for If-Match and If-None-Match were not being

[Brian Havard]
*) Work around a bug in Lynx regarding its sending "Negotiate: trans"

*) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
to util.c for parsing an HTTP header field value to extract the next
list item, taking into account the possible presence of nested comments,
quoted-pairs, and quoted-strings. ap_get_list_item() also removes
insignificant whitespace and lowercases non-quoted tokens.
[Roy Fielding] PR#2065
*) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
code different from 500. This allows the proxy to, e.g., return
"403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
*) Fix ordering of language variants for the case where the traditional
negotiation algorithm is being used with multiple language variants
and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
*) Do not round the TCN quality calculation to 5 decimal places,
unlike RFC 2296, because the calculation might need 12 decimal places
to get the right result. [Roy Fielding]
*) Remove unused code to disable transparent negotiation when
negotiating on encoding only, as we now handle encoding too
(though this is nonstandard for TCN), remove charset=ISO-8859-1
fiddle from the fiddle-averse RVSA comparison, and fix bugs in
some debugging statements within mod_negotiation. [Koen Holtman]
*) Fixed a rare memory corruption possibility in mod_dir if the index
file is negotiable and no acceptable variant can be found.
[Dean Gaudet, Roy Fielding, Martin Kraemer]
*) Win32: Add new config directive, ScriptInterpreterSource, to enable
searching the Win32 registry for script interpreters.
[Bill Stoddard]
*) Win32: The compiled-in default filename for the error log is now
error.log, which matches the default in the distributed httpd.conf.
[Paul Sutton]
*) Win32: Any error messages from -i or -u command line options are now
displayed on the console output rather than sent to the error log.
Also the "Running Apache..." message is not output unless Apache is
going to serve requests. [Paul Sutton]
*) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
and use a private significator ('$apr1$') to mark passwords as
being smashed with our own algorithm. Also abstract the password
checking into a new ap_validate_password() routine. [Ken Coar]
*) Win32: The filename validity checker now allows "COM" but refuses
access to "COM1" through "COM4". This allows filenames such
as "com.name" to be served. [Paul Sutton] PR#3769.
*) BS2000: Adapt to the new ufork() system call interface which will
make subtasking easier on the OSD/POSIX mainframe environment.
[Martin Kraemer]
*) Add a compatibility define for escape_uri() -> ap_escape_uri() to
ap_compat.h. [David White <david@persimmon.com>] PR#3725
*) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
use `.db' instead of `.pag' not only for FreeBSD, but also when
the NDBM library looks like Berkeley-DB based.
[Ralf S. Engelschall] PR#3773

[Ryan Bloom <rbb@Raleigh.IBM.Com>]
*) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]

[Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
*) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
and check to see if the tar we wind up with supports '-h'.
[Jim Jagielski] PR#3671
*) A consistent and conservative style for all shell scripts has been
implemented. Basically, all shell string tests use the traditional
hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
to protect against bare null variable strings (ie: wrapping both
sides with double quotes and prepending 'x'). 'x' was chosen
because it's more universal and hopefully easier for old shell
prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
[Jim Jagielski]
*) The status module now prints out both the main server generation as
well as the generation of each process. Also, the vhost info is
printed with '?notable'. [Jim Jagielski]
*) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
and this makes its functions available to things in src/support.
[Ken Coar]
Changes with Apache 1.3.4
*) Renamed macros status_drops_connection to ap_status_drops_connection
and vestigial scan_script_header to ap_scan_script_header_err,
mostly for aesthetic reasons. [Roy Fielding]
*) The query switch "httpd -S" didn't exit after showing the
vhost settings. That was inconsistent with the other query functions.
[Martin Kraemer]
*) Moved the MODULE_MAGIC_COOKIE from before the versions and
filename to the end of the STANDARD_MODULE_STUFF. Its
presence at the beginning prevented reporting of the filename
for modules compiled before 1 January 1999. [Ken Coar]
*) SECURITY: ap_os_is_filename_valid() has been added to Win32
to detect and prevent access to special DOS device file names.
[Paul Sutton, Ken Parzygnat]
*) WIN32: Created new makefiles Makefile_win32.txt (normal build)
and Makefile_win32_debug.txt (debug build) that work on Win95.
Run each of the following from the src directory:
nmake /f Makefile_win32.txt # compiles normal build
nmake /f Makefile_win32.txt install # compiles and installs
nmake /f Makefile_win32.txt clean # removes compiled junk
nmake /f Makefile_win32_debug.txt # compiles debug build
nmake /f Makefile_win32_debug.txt install
nmake /f Makefile_win32_debug.txt clean
[Roy Fielding]
*) Added binbuild.sh and findprg.sh helpers to make it easier for us
to build binary distributions. [Lars Eilebrecht]
*) IndexOptions SuppressColumnSorting only turned off making
the column headers anchors; you could still change the display
order by manually adding a '?N=A' or similar query string to the
URL. Now SuppressColumnSorting locks in the sort order so
it can't be overridden this way. [Ken Coar]
*) Added IndexOrderDefault directive to supply a default sort order
for FancyIndexed directory listings. [Ken Coar] PR#1699
*) Change the ap_assert macro to a variant that works on all platforms.
[Richard Prinz <richard.prinz@cso.net>] PR#2575
*) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
search for an underscore on dlsym() (as it's already the case
for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
*) Small fix for mod_env.html: The module was documented as to be _not_
compiled into Apache per default, although it _IS_ compiled into
Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
*) Instead of fixing a bug in the generation procedure for config.status (a
backslash was missing) we remove the bug together with it's complete
context because the special cases of the past can now no longer occur
because of the recent magic for the --with-layout default.
[Ralf S. Engelschall] PR#3590
*) Make top-level Makefile aware of a parallel build procedures (make -j) by
making sure the src/support/ tools are _forced_ to be build last (they
depend on other libraries).
[Markus Theissinger <markus.theissinger@gmx.de>]
*) Fix installation procedure: Now that os-inline.c is actually used (a
recently fixed bug prevented this) we need to also install os-include.c
in addition to os.h into the PREFIX/include/ location or building of
module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
*) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
allow us to distinguish between a garbled DSO (or even a file which isn't
an Apache module DSO at all) and a DSO which doesn't match the current
Apache API. [Ralf S. Engelschall] PR#3152
*) Two minor enhancements to mod_rewrite: First RewriteRule now also
supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
match case insensitive (this especially avoids nasty patterns like
`[tT][eE][sS][tT]'). Second two additional internal map functions
`escape' and `unescape' were added which can be used to escape/unescape
to/from hex-encodings in URLs parts (this is especially useful in
combination with map lookups).
[Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
*) Renamed the macro escape_uri() to ap_escape_uri() which was
forgotten (because it was a macro) in the symbol renaming process.
[Ralf S. Engelschall]
*) Fix some inconsistencies related to the scopes of directives. The only
user visible change is that the directives `UseCanonicalName' and
`ContentDigest' now use the (more correct) `Options' scope instead of
(less correct) `AuthConfig' scope. [Ralf S. Engelschall]
*) Using DSO, the Server token was being mangled. Specifically, the
module's token was being added first before the Apache token. This
has been fixed. [Jim Jagielski]
*) Major overhaul of mod_negotiation.c, part 2.
- properly handle "identity" within Accept-Encoding.
- allow encoded variants in RVSA negotiation and let them appear in
the Alternates field using the non-standard "encoding" tag-list.
- fixed both negotiation algorithms so that an explicitly accepted
encoding is preferred over no encoding if "identity" is not
included within Accept-Encoding.
- added ap_array_pstrcat() to alloc.c for efficient concatenation
of large substring sequences.
- replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
[Roy Fielding]
*) Major overhaul of mod_negotiation.c, part 1.
- cleanups to mod_negotiation comments and code structure
- made compliant with HTTP/1.1 proposed standard (rfc2068) and added
support for everything in the upcoming HTTP/1.1
revision (draft-ietf-http-v11-spec-rev-06.txt).
- language tag matching also handles tags with more than 2
levels like x-y-z
- empty Accept, Accept-Language, Accept-Charset headers are
processed correctly; previously an empty header would make all
values acceptable instead of unacceptable.
- allowed for q values in Accept-Encoding
- added support for transparent content negotiation (rfc2295 and
rfc2296) (though we do not implement all features in these drafts,
e.g. no feature negotiation). Removed old experimental version.
- implemented 'structured entity tags' for better cache correctness
(structured entity tags ensure that caches which can deal with Vary
will (eventually) be updated if the set of variants on the server
is changed)
- this involved adding a vlist_validator element to request_rec
- this involved adding the ap_make_etag() function to the global API
- modified guessing of charsets used by Apache negotiation algorithm
to guess 'no charset' if the variant is not a text/* type
- added code to sort multiviews variants into a canonical order so that
negotiation results are consistent across backup/restores and mirrors
- removed possibility of a type map file resolving to another type map
file as its best variant
[Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987

*) The hashbang emulation code in ap_execve.c would interpret
#!/hashbang/scripts correctly, but failed to fall back to a
standard shell for scripts which did NOT start with #!
Now SHELL_PATH is started in these cases. [Martin Kraemer]
*) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
PR#3336
*) Update APXS manual page: some -q option arguments were missing
and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
*) Cleanup the command line options: `-?' was documented to show
the usage list but does it with an error because `?' is not a valid
command. OTOH a lot of users expect `-h' to print such a usage list and
instead are annoyed for ages by our huge unreadable list of directives.
So we now changed the command line options this way:
1. `-L' => `-R'
Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
very similar to the popular linker option.
2. `-h' => `-L'
Intent: while -l gives the small list of modules, -L now gives the
large list of directives implemented by these modules. This is also
consistent with -v (short version info) and -V (large version info).
3. `-?' => `-h'
Intent: it's now the expected option ;-)
The manual page was adjusted accordingly.

*) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
wasn't defined. [Rick Franchuk <rickf@transpect.net>]
*) Removed recently introduced bugs and disfigurements in APACI:
o fixed argument line processing: using $args was broken: It was not
initialized and using args="$args $apc_option" and even args="$args
\"$apc_option\"" fails in the second processing round for any arguments
containing whitespaces. The only correct way is to use the construct
"$@" (but not possible here) or iterate _both_ times over the implicit
argument line (no argument to for-loop) which is what we now use.
o make --with-layout=Apache the default without creating
redundancy (copying the --with-layout block in the argument parsing
loop). We achieve this by using the "$@" construct together with the
`set' command to prepend --with-layout=Apache to the command line in
case --with-layout is not used.
o fixed auto-suffix handling now that config.layout exists.
Paths which are auto-suffixed are marked with a trailing plus sign in
config.layout and every path now can be marked this way (not only the
four paths for which we do it currently). Additionally the suffix is
no longer a static one. Instead it's now `/<target>' where <target> is
the argument of the --target option or per default `httpd'.
o allow also tabs (and only spaces) where we match whitespaces
o various fixes and cleanups related to used shell coding style
o made Jim happy by replacing `Written by' with `Initially written by' ;-)
o trimmed output of --help to fit into 80 columns

*) Make generation of src/Configuration.apaci more robust: It failed to
differenciate between modules when one module name was a postfix of

just XXX (think about totally non-standard names like "apache_ssl", too).

[Ralf S. Engelschall] PR#3240
*) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
creates an external package shadow tree in DIR before the local build
shadow tree is generated under DIR. This way one can have the extracted
Apache distribution tree read-only on NFS or CDROM and still build Apache
from these sources. An automatically triggered VPATH-like mechanism is
provided through the TOP variable, too.

*) Fixed possible (but harmless in practice) bug in the DBM lookup
procedure of mod_rewrite: very long keys were truncated.
[Ralf S. Engelschall]
*) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
identifier, currently "Apache" and "GNU" are pre-defined in the file
config.layout. Custom layouts are possible by using FILE:ID as the
argument where the layout ID is taken from FILE.
The config.layout file consists of <Layout ID>..</Layout> sections
where inside those sections "path_variable: path_value" pairs can be
specified. These lines are converted to path_variable='path_value'.
*) Add a DefaultLanguage directive so that files missing a language

default language. DefaultLanguage can appear in <Directory> and
<Files> containers as well as .htaccess files. [Paul Sutton]

in the Configuration[.apaci] file. Two special and important variants are
supported for the option argument: first BEGIN:foo which permutes module
mod_foo with the begin of the module list, i.e. it `moves' the module to
the begin of the list (gives it lowest priority). And second foo:END
which permutes mod_foo with the end of the module list, i.e. it `moves'
the module to the end of the list (gives it highest priority).

*) Remove extra trailing whitespace from the getline results as part
of the protocol processing, which is extra nice because it works
between continuation lines, is almost no cost in the normal case
of no extra whitespace, and saves memory. [Roy Fielding]
*) Added new HTTP status codes and default response bodies from the
revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
HTTP Extension Framework (510) specifications. Did not add the

pre-processor pass only (and no longer the complete compiler pass) to
determine whether a C header file exists or not. Because only this way
we're safe against inter-header dependencies (which caused horrible
portability problems). The only drawback is that we now have a CPP
configuration variable which has to be determined first (we do a similar
approach as GNU Autoconf does here). When all fails the user still has
the possibility to override it manually via APACI or src/Configuration.
As a fallback for the header check itself we can directly check the
existance of the file under /usr/include, too.

*) The <IfModule and <IfDefine block starting directives now only
allow exactly one argument. Previously, the optional negation
character '!' could be separated by whitespace without a syntax
error being reported, albeit defeating the IfModule functionality
(enclosed directives would ALWAYS be executed). By using the
stricter syntax, these hard-to-track errors can be avoided.
[Martin Kraemer]
*) Simplify handling of IndexOptions in mod_autoindex -- and BTW

*) Changes in ftp proxy: make URL parsing simpler by using the
parsed_uri stuff.
+ Add display of the "current directory" in cases where it's
different from the supplied path (e.g., ftp://user@host/ lives
in /home/user, not in /, therefore clicking on "../" in the
starting directory might send us to /home/).
+ When ftp login fails, (esp. when a user name was part of the
URL already), we now return [401 Unauthorized ] to allow the
browser to pop up an authorization dialog. This makes passwords
slightly less visible (they don't appear in the regular log files)
and implements a functionality that other www proxy servers
already offered.
[Martin Kraemer]
*) Triggered by the recent "Via:" header changes, the proxy module would
dump core for replies with invalid headers (e.g., duplicate
"HTTP/1.0 200 OK" lines). These errors are now logged and the
core dump is avoided. Also, broken replies are not cached.

*) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
-Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
without complains after we recently added the POST feature.
[Ralf S. Engelschall]
*) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
modules as API functions and we forgot them at the big symbol renaming.

[Kurt Sussman <kls@best.com>] PR#2871
*) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
5 to 10 because there are some users out there who always have 5 to 8
variables in one RewriteRule and had to patch mod_rewrite.h for every
release. So 15 should be now more than enough, even for them. (I never
needed more than 4 in my RewriteRules ;-)
[Ralf S. Engelschall]
*) Make the proxy generate and understand Via: headers
[Martin Kraemer]
*) Change the proxy to use tables instead of array_headers for
the header lines. [Martin Kraemer]
*) Make sure the config.status file is not overridden when just
``configure --help'' is used. [Ralf S. Engelschall] PR#2844
*) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
provide a way to trace API changes that add functionality but do
not create a compatibility issue for precompiled modules, etc.
See include/ap_mmn.h for more details. [Randy Terbush]
*) Fix suexec installation under `make install root=xxx' situation.
[Ralf S. Engelschall]
*) Extend the output of the -V switch to include the paths of all
compiled-in configuration files, if they were overridden at
compile time, for least astonishment of the user.
[Martin Kraemer]
*) When READing a request in ExtendedStatus mode, the "old"
vhost, request and client information is not displayed.
[Jim Jagielski]
*) STATUS is no longer available. Full status information now
run-time configurable using the ExtendedStatus directive.
[Jim Jagielski]
*) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
cpu time attacks) in header parsing. Add ap_overlap_tables(),
a function which can be used to perform bulk update operations
on tables in a more efficient manner. [Dean Gaudet]
*) SECURITY: Added compile-time and configurable limits for
various aspects of reading a client request to avoid some simple
denial of service attacks, including limits on maximum request-line
size (LimitRequestLine), number of header fields (LimitRequestFields),
and size of any one header field (LimitRequestFieldsize). Also added
a configurable directive LimitRequestBody for limiting the size of the
request message body. [Roy Fielding]
*) Make status module aware of DNS and logging states, even if
STATUS not defined. [Jim Jagielski]
*) Fix a problem with the new OS/2 mutexes. [Brian Havard]
*) Enhance mod_speling so that CheckSpelling can be used in
<Directory> containers and .htaccess files. [Ken Coar]
*) API: new ap_custom_response() function for hooking into the
ErrorDocument mechanism at runtime [Doug MacEachern]
*) API: new ap_uuencode() function [Doug MacEachern]
*) API: scan_script_header_err_core() now "public" and renamed
ap_scan_script_header_err_core() [Doug MacEachern]
*) The 'status' module will now show the process pid's and their
state even without full STATUS accounting. [Jim Jagielski]
*) Restore the client IP address to the error log messages, this
was lost during the transition from 1.2 to 1.3. Add a new
function ap_log_rerror() which takes a request_rec * and
formats it appropriately. [Dean Gaudet] PR#2661
*) Cure ap_cfg_getline() of its nasty habit of compressing internal
whitespace in input lines -- including within quoted strings.
[Ken Coar]
but leading and trailing whitespace should continue to be
stripped [Martin Kraemer]
*) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
the ugly use of an env. variable and use command-line args for
alternate $PATH. Make more like advanced 'type's as well.
[Jim Jagielski]
*) The IRIXN32 Rule was being ignored. Configure now correctly adds
-n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
<alain.st-denis@ec.gc.ca>] PR#2736
*) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
*) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
directory was renamed to src/os/os2/ for consistency.
[Brian Havard, Ralf S. Engelschall]
*) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
files (here modules) against other DSO files (here shared libraries).
This is done by determining a subset of LIBS which can be safely used for
linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
disabled for all platforms to avoid problems with this (experimental)
rule. But we provide it now for those people how ran into problems and
want to came out by forcing linking against DSOs.
[Ralf S. Engelschall] PR#2587
*) Fix suEXEC start message: Has to be of `notice' level to really get
printed together with the standard startup message because the `notice'
level is handled special inside ap_log_error() for startup messages.

[Youichirou Koga <y-koga@jp.FreeBSD.org>, Ralf S. Engelschall] PR#2756
*) Allow ap_read_request errors to propagate through the normal request
handling loop so that the connection can be properly closed with
lingering_close, thus avoiding a potential TCP reset that would
cause the client to miss the HTTP error response. [Roy Fielding]
*) One more portability fix for APACI shadow tree support: Swap order of awk
and sed in top-level configure script to avoid sed fails on some
platforms (for instance SunOS 4.1.3 and NCR SysV) because of the
non-newline-termined output of Awk. [Ralf S. Engelschall] PR#2729
*) PORT: NEC EWS4800 support.
[MATSUURA Takanori <t-matsuu@protein.osaka-u.ac.jp>]
*) Fix a segfault in the proxy on OS/2. [Brian Havard]

structure instead of just NULL. This fixes at least the RewriteMap
programs under Win32. [Marco De Michele <mdemichele@tin.it>] PR#2483
*) Add workaround to top-level `configure' script for brain dead
`echo' commands which interpet escape sequences per default.

Makefile.tmpl: The umask+cp approach didn't work as expected (especially
for users which extracted the distribution under 'umask 077'), so replace
it by an explicit cp+chmod approach.
[Richard Lloyd, Curt Sampson, Ralf S. Engelschall] PR#2656 PR#2626
*) Fix `distclean' and `clean' targets in src/Makefile.tmpl to have same
behavior and to cleanup correctly even under enabled SHARED_CORE rule.
[Ralf S. Engelschall]
*) Use a more straight forward and thus less problematic Sed command in
src/helper/mkdir.sh script. [Ralf S. Engelschall]

domainname of the machine and there are multiple `domainname' and
`search' entries in /etc/resolv.conf.
[Ralf S. Engelschall] PR#2710
*) Add note about the SHARED_CORE requirement on some platforms also to the
INSTALL file because a lot of users don't read htdocs/manual/dso.html

engine does any manipulations or decisions based upon request fields.
[Ken Coar] PR#1644
*) Document the special APACI behavior for installation paths where
``/apache'' is appended to paths under some (well defined, of course)
situations to prevent pollution of system locations with Apache files.
[Ralf S. Engelschall] PR#2660
*) Fixed problem with buffered response message not being sent for
the read_request error conditions of URI-too-long (414) and
malformed header fields (400). [Roy Fielding] PR#2646
*) Add support for the Max-Forwards: header line required by RFC2068 for
the TRACE method. This allows apache to TRACE along a chain of proxies
up to a predetermined depth. [Martin Kraemer]
*) Fix SHARED_CORE rule: The CFLAGS_SHLIB variable is no longer doubled
(compilers complained) and the .so.V.R.P filename extension was adjusted
to correctly reflect the 1.3.2 version.
[Ralf S. Engelschall] PR#2644
*) SECURITY: Plug "..." and other canonicalization holes under OS/2.
[Brian Havard]
*) PORT: implement serialized accepts for OS/2. [Brian Havard]
*) mod_include had problems with the fsize and flastmod directives
under WIN32. Fix also avoids the minor security hole of using
".." paths for fsize and flastmod.
[Manoj Kasichainula <manojk@raleigh.ibm.com>] PR#2355
*) Fixed some Makefile dependency problems. [Dean Gaudet]
Changes with Apache 1.3.1
*) Disable the incorrect entry for application/msword in the
mod_mime_magic "magic" file because it also matches other Office
documents. [Ralf S. Engelschall] PR#2608
*) Fix broken RANLIB handling in src/Configure (the entry from
src/Configuration.tmpl was ignored) and additionally force RANLIB to
/bin/true under HP/UX where ranlib exists but is deprecated.
[Ralf S. Engelschall] PR#2627
*) 'apachectl status' failed on some systems.
[Steve VanDevender <stevev@darkwing.uoregon.edu>, Lars Eilebrecht] PR#2613
*) Add new flags for ap_unparse_uri_components() to make it generate
the scheme://sitepart string only, or to omit the query string.
[Martin Kraemer]
*) WIN32: Canonicalize ServerRoot before checking to see if it
is a valid directory. The failure to do this caused certain
ServerRoot settings (eg. "ServerRoot /apache") to be improperly
rejected. [Marc Slemko]
*) Global renaming of C header files to both get rid of conflicts with third
party packages and to again reach consistency:
1. conf.h -> ap_config.h
2. conf_auto.h -> ap_config_auto.h \ these are now merged
3. ap_config.h -> ap_config_auto.h / in the config process
4. compat.h -> ap_compat.h
5. apctype.h -> ap_ctype.h
Backward compatibility files for conf.h and compat.h were created.
*) mod_mmap_static will no longer take action on requests unless at
least one "mmapfile" directive is present in the configuration.
This experimental module has to do some black magic to operate
inside the current API and thus creates side-effects for other
modules under some circumstances.
[Ralf S. Engelschall]
*) Add conservative ticks around more egrep arguments in top-level configure
to avoid problems under brain-dead platforms like Digital UNIX (OSF1).
[Ralf S. Engelschall] PR#2596
*) mod_rewrite created RewriteLock files under the UID of the parent
process, thus the child processes had no write access to the files.
Now a chown() is done on the file to the uid of the children,
if applicable. [Lars Eilebrecht, Ralf S. Engelschall] PR#2341
*) Autogenerate some HAVE_XXXXX_H defines in conf_auto.h (determined via
TestCompile) instead of defining them manually in conf.h based on less
accurate platform definitions. This way we no longer have to fiddle with
OS-type and/or OS-version identifiers to discover whether a system header
file exists or not. Instead we now directly check for the existence of
those esoteric ones.

PR#2524, PR#2525, PR#2533, PR#2569
*) mod_setenvif (BrowserMatch* and friends) will now match a missing
field with "^$". [Ken Coar]
*) Set the RTLD_GLOBAL dlopen mode parameter to allow dynamically loaded
modules to load their own modules dynamically. This improves mod_perl
and mod_php3 when these modules are loaded dynamically into Apache.
[Rasmus Lerdorf]
*) Cache a proxied request in the event that the client cancels the
transfer, provided that the configured percentage of the file has
already been transfered. It works for HTTP transfers only. The
new configuration directive is called CacheForceCompletion.
[Glen Parker <glenebob@nwlink.com>] PR#2277
*) Add the "<!DOCTYPE HTML" magic cookie used by modern documents (and
required by HTML 3.2 and later) to mod_mime_magic's conf/magic.
[Anna Shergold <anna@inext.co.uk>]
*) Fix yet another signal-based race condition involving nested timers.
Signals suck. [Dean Gaudet]
*) suexec's error messages have been clarified a little bit. [Ken Coar]
*) Clean up some, but perhaps not all, 8-bit character set problems
with config file parsing, and URL parsing. We now define
ap_isdigit(), ap_isupper(), ... which cast to an (unsigned char).
This should work on most modern unixes.
[Dean Gaudet] PR#800, 2282, 2553 (and others)
*) The "handler not found" error was issued in cases where the handler
really did exist, but was just declining to serve the request.

*) Add Dynamic Shared Object (DSO) support for SCO5 (OpenServer 5.0.x).
[Ronald Record <rr@sco.com>] PR#2533
*) The APACI libexecdir was not extended with an "apache/" subdir
if the installation prefix didn't already contain "apache", but
it should be because the DSO files are Apache-specific. Now
libexecdir is treated the same way sysconfdir, datadir, localstatedir
and includedir are already treated.
[Charles Levert <charles@comm.polymtl.ca>] PR#2551
*) The <Limit> parsing routine was incorrectly treating methods as
case-insensitive. [Ken Coar]
*) The ap_bprintf() code neglected to test if there was an error on

[Doug MacEachern]
*) API: Name changes of table_elts to ap_table_elts, is_table_empty
to ap_is_table_empty and bgetflag to ap_bgetflag. [Ben Laurie]
*) PORT: Add UnixWare 7 support
[Vadim Kostoglodoff <vadim@olly.ru>] PR#2463
*) Fix the Guess-DSO-flags-from-Perl stuff in src/Configure: "perl" was
used instead of "$PERL" which contains the correctly determined Perl
interpreter (important for instance on systems where "perl" and "perl5"
exists, like BSDI or FreeBSD, etc).
[Ralf S. Engelschall] PR#2505
*) Move the initial suEXEC-related startup message from plain
fprintf()/stderr to a delayed ap_log_error()-based one to avoid problems
when Apache is started from inetd (instead of standalone). Under this
situation startup messages on stderr lead to problems (the line is sent
to the client in front of the requested document).
[Ralf S. Engelschall] PR#871, PR#1318

*) We now attempt to dump core when we get SIGILL. [Jim Jagielski]
*) PORT: remove broken test for MAP_FILE in http_main.c.
[Wilfredo Sanchez <wsanchez@apple.com>]
*) PORT: Change support/apachectl to use "kill -0 $pid" to test if the
httpd is running. This should be more portable than figuring out
which of three dozen different versions of "ps" are installed.
[a cast of dozens]
*) WIN32: If we can't figure out how to execute a file in a script
directory, bail out of the request with an error message. [W G Stoddard]
*) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
these are treated by Win32 as if they are ".." but are not detected by
other machinery within Apache. This is something of a kludge but
eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
*) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
pools and thus pollutes libap (until the pool stuff is moved there).
[Ken Coar]
*) IndexIgnore should be case-blind on Win32 (and any other case-aware
but case-insensitive platforms). New #define for this added to conf.h
(CASE_BLIND_FILESYSTEM). [Ken Coar] PR#2455
*) Enable DSO support for OpenBSD in general, not only for 2.x, because it
also works for OpenBSD 1.x. [Ralf S. Engelschall]
*) PORT: Fix compilation problem on ARM Linux.
[Sam Kington <sam@illuminated.co.uk>] PR#2443
*) Let APACI's configure script determine some configuration parameters
(Group, Port, ServerAdmin, ServerName) via some intelligent tests to
remove some of the classical hurdles for new users when setting up
Apache. This is done per default because it is useful for the average
user. Package authors can use the --without-confadjust option to disable
these configuration adjustments.
[Ralf S. Engelschall]
*) Added an EXTRA_DEPS configuration parameter which can be used
to add an extra Makefile dependency for the httpd target, for instance
to external third-party libraries, etc.
[Ralf S. Engelschall]
*) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
as <IfModule>..</IfModule> sections) which can be used to skip or process
contained commands dependend of ``-D PARAMETER'' options on the command
line. This can be used to achieve logical conditions like <IfDefine
ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
and thus especially can be used for conditionally loading DSO-based
modules via LoadModule, etc. [Ralf S. Engelschall]
*) PORT: clean up a warning in mod_status for OS/2. [Brian Havard]
*) Make table elements const. This may prevent obscure errors. [Ben Laurie]
*) Fix parsing of FTP `SIZE' responses in proxy module: The newline was not
truncated which forced following HTTP headers to be data in the HTTP

PR#2412, 2367
*) Portability fix for APACI shadow tree support: Swap order of awk and sed
in top-level configure script to avoid sed fails on some platforms (for
instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
*) Improve performance of directory listings (mod_autoindex) by comparing
integer keys (last-modified and size) as integers rather than converting
them to strings first. Also use a set of explicit byte tests rather
than strcmp() to check for parent directory-ness of an entry. Oh, and
make sure the parent directory (if displayed) is *always* listed first
regardless of the sort key. Overall performance winnage should be good
in CPU time, instruction cache, and memory usage, particularly for large
directories. [Ken Coar]
*) Add a tiny but useful goody to APACI's configure script: The generation
of a config.status script (as GNU Autoconf does) which remembers the used
configure command and hence can be used to restore the configuration by
just re-running this script or for remembering the configuration between
releases.
[Ralf S. Engelschall]
*) Add httpd -t (test) option for running configuration syntax tests only.
If something is broken it complains and exits with a return code
non-equal to 0. This can be used manually by the user to check the Apache
configuration after editing and is also automatically used by apachectl
on (graceful) restart command to make sure Apache doesn't die on restarts
because of a configuration which is now broken since the last (re)start.
This way `apachectl restart' can be used inside cronjobs without having
to expect Apache to be falling down. Additionally the httpd -t can be run
via `apachectl configtest'.
[Ralf S. Engelschall] PR#2393

because of a return code of 1 from an "if" (for instance under braindead
Ultrix the result code of an "if" construct is 1 if the "then" clause
didn't match). [Ralf S. Engelschall]
*) Add an additional "dummy" target to the "$(LIB)" target in generated

[Brian Behlendorf]
*) Upgrade the child spawning code in mod_rewrite for the RewriteMap
programs: ap_spawn_child_err() is used and the Win32 case now uses
CreateProcess() instead of a low-level execl() (which caused problems in
the past under Win32).
[Ralf S. Engelschall]
*) A few cosmetics and trivial enhancements to APXS to make the
generated Makefile more user friendly. [Ralf S. Engelschall]
*) Proxy Fix: The proxy special failure routine ap_proxyerror()
was updated to use the normal apache error processing, thereby allowing
proxy errors to be treated by ErrorDocument's as well. For this
purpose, a new module-to-core communication variable "error-notes"
was introduced; the proxy (and possibly other modules) communicates
its error text using this variable. Its content is copied to a new
cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
The old proxy special error routine ap_proxy_log_uerror()
was replaced by regular ap_log_error() calls, many messages were made
more informative.
[Martin Kraemer] PR#494, 1259
*) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
[Martin Kraemer]
*) Transform the configure message "You need root privileges for suEXEC"
from a fatal error into a (more friendly) warning because the building
("make") of Apache we can allow, of course. Root privileges are needed
only for the installation step ("make install"). So make sure the
user is aware of this fact but let him proceed as long as he can.
[Ralf S. Engelschall] PR#2288

*) A zero-length name after a $ in an SSI document should cause
just the $ to be in the expansion. This was broken during the
security fixes in 1.2.5. [Dean Gaudet] PR#1921, 2249
*) Call ap_destroy_sub_req() in ap_add_cgi_vars() to reclaim some
memory. [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2252

used under AIX) because of recent changes to function names.

Changes with Apache 1.3b7
*) Make sure a MIME-type can be forced via a RewriteRule even when no
substitution takes place, for instance via the following rule:
``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
requested by users in the past to force a single script without a .cgi
extension and outside any cgi-bin dirs to be executed as a CGI program.
[Ralf S. Engelschall] PR#2254
*) A fix for protocol issues surrounding 400, 408, and
414 responses. [Ed Korthof]
*) Ignore MaxRequestsPerChild on WIN32. [Brian Behlendorf]
*) Fix discrepancy in proxy_ftp.c which was causing failures when
trying to connect to certain ftpd's, such as anonftpd.
[Rick Ohnemus <rick@ecompcon.com>]
*) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
logfile instead of fiddling around itself with child spawning stuff.
[Ralf S. Engelschall]
*) Made RefererIgnore case-insensitive.
*) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
[Brian Behlendorf]
*) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
"safe" under Win32. In: mod_include.c, mod_mime_magic.c
[Brian Behlendorf]
*) Improve RFC1413 support. [Bob Beck <beck@bofh.ucs.ualberta.ca>]

of passwords, especially passwords with "0" chars.
[Ralf S. Engelschall] PR#2242
*) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
[Ben Laurie] PR#2238
*) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
library), so CGI handling has been changed to use Win32 native handles
instead of C file descriptors.
[Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
*) The proxy cache would store an incorrect content-length in the cached
file copy after a cache update. That resulted in repeated fetching
of the original copy instead of using the cached copy.
[Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
*) The Makefiles assumed that DSO files are build via $(LD). This
is broken for two reasons: First we never defined at least LD=ld
somewhere to make sure this works (it was silently assumed that most Make
provide a built-in LD definition - ARGL!) and second using the generic LD
variable is not the truth. Instead a special variable named LD_SHLIB is
reasonable because although "ld" is usually the default, the command for
building DSO files can be "libtool" or even "cc" on some systems.
[Ralf S. Engelschall]
*) Replace the AddVersionPlatform directive with ServerTokens which
provides for more control over the format of the Server:
header line. SERVER_SUBVERSION is no longer supported;
all module should use the ap_add_version_component()
API function instead. [Jim Jagielski]
*) Support for the NCR MP/RAS 3.0
[John Withers <withers@semi.kcsc.mwr.irs.gov>]
*) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
not retrieved in src/Configure and thus was not useable.
[Ralf S. Engelschall]
*) Various Makefile consistency cleanups:
- make OSDIR also automatically be relative to src/ like INCDIR
- SUBDIRS is now generated in src/Makefile only and not in
Makefile.config because it is a local define for this location.
- remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
any Makefile but make sure that at least the "-K inline" is kept in
CFLAGS for SCO 5.
- update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
- updated the dependencies theirself
- removed not existing SHLIB variable from "clean" targets
- replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
already exists and OBJS_PIC are also just plain objects and have not
directly to do with "shared" things. The only difference is that they
contain PIC. So OBJS_PIC is the more canonical name.
- Updated the Makefile-dependency lines for OBJS_PIC
- Removed the Makefile-dependency line in Configure to avoid double
definitions
- replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
of xxx.lo as GNU libtool does with its PIC objects
- reduce local complexity in modules Makefile.tmpl by moving the last
existing target "depend" to the generation section in Configure, too.
- removed the historical $(SPACER) which was used in the past together
with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
is no longer needed.
- force the build and run of the gen_xxx programs under main/ as the
first step before building the objects because it looks cleaner

[Ben Laurie]
*) WIN32: Don't force ISAPI headers to finish with \n.
[Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
*) When opening "configuration" files (like httpd.conf, htaccess
and htpasswd), Apache will not allow them to be non-/dev/null
device files. This closes a DoS hole. At the same time,
we use ap_pfopen to open these files to handle timeouts.
[Jim Jagielski, Martin Kraemer]
*) Apache will now log the reason its httpd children exit if they exit
due to an unexpected signal. (It requires a new porting define,
SYS_SIGLIST, which if defined should point to a list of text
descriptions of the signals available. See PORTING.) [Dean Gaudet]
*) WIN32: chdir() doesn't make sense in a multithreaded environment
like WIN32. Before, Win32 CGI's could have had sporadic failures
if a chdir call from one thread was made between another chdir call
and a spawn in another thread. So, for now don't chdir for CGI scripts
in WIN32. The current CGI "spec" is unclear as to whether it's
necessary. Long-term fix is to either serialize the chdir/spawn combo
or use WIN32 native calls to spawn a process. This temp fix was
necessary to remove this as a showstopper for 1.3's release.
[Brian Behlendorf]
*) Cleanup the suEXEC support in APACI and make it more safe:
1. Add big fat hint in INSTALL about risks and to read the
htdocs/manual/suexec.html document before using the suexec-related
configure options.
2. Make sure the user has at least provided one --suexec-xxxx option
(specifies suEXEC parameters) in addition to --enable-suexec option.
If only --enable-suexec is given APACI stops with a hint to INSTALL
and htdocs/manual/suexec.html documents.
3. Provide two additional --suexec-xxxx options to make the suEXEC
configuration complete (especially for package maintainers who else
had to patch the source tree) by providing ways to configure minimal
UID/GID and safe PATH, too.
[Ralf S. Engelschall]
*) Cleanup of the `configure --shadow' process:
- make sure the configure script creates its temporary files in the
shadow tree to avoid conflicts with parallel configure runs
- removed unnecessary option "-r" from "rm" call for Makefiles
- make sure the configure scripts creates the shadow-wrapper Makefile
only when no shadow trees already exists
- make sure "make distclean" removes the shadow-wrapper Makefile but only
when no more shadow trees exists
- overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
as fast (in the past it needed 70sec, now it runs just 38sec)
- make sure CVS does not complain about the created files
Makefille.<gnutriple> and directories src.<gnutriple>
[Ralf S. Engelschall]
*) Added the ap_add_version_component() API routine and the
AddVersionPlatform core directive. The first allows modules to
declare themselves in the Server response header field value,
augmenting the SERVER_SUBVERSION define in the Configuration file
with run-time settings (more useful in a loadable-module environment).
AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
into the server version string. [Ken Coar] PR#2056
*) Minor stability tweaks to avoid core dumps in ap_snprintf.
[Martin Kraemer]
*) Emit the "Accept-Range" header for the default handler.
[Brian Behlendorf] PR#1464
*) Add a note to httpd.conf-dist that apache will on some systems fail
to start when the Group # is set to a negative or large positive value.
[Martin Kraemer]
*) Make sure the module execution order is correct even when some modules
are loaded under runtime (`LoadModule') via the DSO mechanism:
1. The list of loaded modules is now a dynamically allocated one
and not the original statically list from modules.c
2. The loaded modules are now correctly setup by LoadModule for
later use by the AddModule command.
3. When the DSO mechanism for modules is used APACI's `install'
target now enables all created `LoadModule' lines per default because
this is both already expected by the user _and_ needed to avoid
confusion with the next point and reduces the Makefile.tmpl complexity
4. When the DSO mechanism for modules is used, APACI's `install'
target now additionally makes sure the module list is reconstructed
via a complete `ClearModuleList+AddModule...' entry.
5. The support tool `apxs' now also makes sure an AddModule command
is added in addition to the LoadModule command.
6. The modules.c generation was extended to now contain two
comments to make sure no one is confused by the confusing terminology
of loading/linking (we use load=link+load & link=activate instead of
the obvious load=activate & link=link :-( )
This way now there is no longer a difference under execution time between
statically and dynamically linked modules.
[Ralf S. Engelschall]
*) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
Big Symbol Renaming. [Ralf S. Engelschall]

*) Standardized the time format in mod_status to match that of other
places in the code (e.g. DATE_GMT). PR#1551
*) Fix handling of %Z in timefmt strings for those platforms with no time
zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
PR#754
*) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
feature compatible with 'UseCanonicalName off' by changing
r->server->server_hostname to ap_get_server_name(). And I changed some
functions which use r->server->port to use ap_get_server_port() instead,
because if there's no Port directive in the config r->server->port is 0.
[Lars Eilebrecht]
*) get/set_module_config are trivial enough to be better off inline. Worth
1.5% performance boost. [Dean Gaudet]
*) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
Brian Behlendorf]
*) [BS2000 security] BS2000 needs an extra authentication to initialize
the task environment to the unprivileged User id. Otherwise CGI scripts
would have a way to gain super user access. [Martin Kraemer]
*) Fix debug log messages for BS2000/OSD: instead of logging the whole
absolute path, only log base name of logging source as is done
in unix. [Martin Kraemer]
*) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
the encoding type from the Accept-Encoding header (if it's there)
and use it in the response, as that's probably what it'll be expecting.
[Ronald.Tschalaer@psi.ch]
*) Fix to mod_alias: translate_alias_redir is dealing with
a URI, not a filename, so the check for drive letters for win32

PR#1558
*) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
Additionally the checks for finding the vendor DSO library were moved
from mod_so.c to Configure because first it needs $PLAT etc. and second
mod_so already uses an abstraction layer and does not fiddle with the
vendor functions itself.
[Jens-Uwe Mager, Ralf S. Engelschall]
*) PORT: Some optimization defines for NetBSD
[Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
*) PORT: Dynamic Shared Object (DSO) support for NetBSD.
[Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
*) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
AIX variants should work fine, too. Even AIX 3.x should work). This is
accomplished by using the free DSO emulation code from Jens-Uwe Mager
which we put into a os/unix/os-dso-aix.c file.
[Ralf S. Engelschall]
*) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
that we should use NET_SIZE_T == int but the include files force size_t.
[Ralf S. Engelschall]
*) Fix two bugs in select() handling in http_main.c.
[Roy Fielding]
*) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
is unset (as it is in situations like timeouts) where it is unclear
whether errno is set or not. [Martin Kraemer]
*) Just having APACI's localstatedir is too general and not enough for most
of the systems. 1.3b6 again required manual APACI patches by package
maintainers from RedHat and FreeBSD because for their filesystem layout a
little bit more flexibility in configuring the paths is needed. Hence we
provide three additional configure options (--runtimedir, --logfiledir,
--proxycachedir) which now can be used for more granular adjustments if
--localstatedir is not enough to fit the particular needs. As a nice
side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
[Ralf S. Engelschall]
*) Make the install root for "make install" in APACI's Makefile overrideable
by package authors. This way we are even more friendly to package
maintainers (especially Debian and RedHat) who build for the real prefix
via "configure --prefix=/<real>" but use a different local prefix via
"make root=/tmp/apache install" for rolling the package without bristling
the target location on their system.
[Ralf S. Engelschall]

substituting in chunks of 50 commands (because for instance HPUX's vendor
sed has a limit of max. 98 commands)

*) Adding SOCKS5 support and fixing existing SOCKS4 support.
[Ralf S. Engelschall] PR#2140
*) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
RENAMING process because they are defined as pre-processor macros instead
of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
[Ralf S. Engelschall]
*) Workaround braindead AWK's when generating ap_config.h: The split() and
substr() functions cannot be nested under vendor AWK from Solaris 2.6.
[Ralf S. Engelschall] PR#2139
*) Various bugfixes and cleanups for the APACI configure script:
o fix IFS handling for _nested_ situation
o fix Perl interpreter search: take first one found instead of last one
o fix DSO consistency check
o print error messages to stderr instead of stdout
o add install-quiet for --shadow situation to Makefile stub
o reduce complexity by avoiding sed-hacks for rule and module list loops
[Ralf S. Engelschall]
*) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
*) Make sure the input field separator (IFS) shell variable is explicitly
initialized correctly before _every_ `for' loop and also restored after
the loops. [Ralf S. Engelschall]
*) Make sure that "make install" doesn't overwrite the `mime.types' and
`magic' files from an existing Apache installation. Because people often
customize these for own MIME and content types.
[Ralf S. Engelschall]
*) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
[Peter Galbavy, Ralf S. Engelschall] PR#2109
*) Fix the path to the ScoreBoardFile in the install-config target, too.
[Ralf S. Engelschall] PR#2105
*) Let "configure" clear out the users parameters (provided as shell
variables) to avoid side-effects in "src/Configure" when the user
exported them (which is not needed, but some users do it).
[Ralf S. Engelschall] PR#2101
*) Provide backward compatibility from some old src/Configuration.tmpl
parameter names to the canonical Autoconf-style shell variable names. For
instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
but a hint message is displayed. [Ralf S. Engelschall]
*) Make sure that "make install" doesn't overwrite the DocumentRoot and
CGI scripts from an existing Apache installation.
[Ralf S. Engelschall, Jim Jagielski] PR#2084
*) Make `configure --compat' more "compatible" by first
let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
second by making sure the "avoid-bristling-suffix" /apache is not
appended to sysconfdir, datadir, localstatedir and includedir when
--compat is used. [Ralf S. Engelschall, Lars Eilebrecht]

*) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
*) If you start apache with the -S command line option it will dump
out the parsed vhost settings. This is useful for folks trying
to figure out what is wrong with their vhost configuration.
(Other dumps may be added in the future.) [Dean Gaudet]
*) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
ap_snprintf, and ap_psprintf). See include/ap.h for docs.
[Dean Gaudet]
*) Because /usr/local/apache is the default prefix the ``configure
--compat'' option no longer has to set prefix, again. This way the
--compat option honors a leading --prefix option. [Lars Eilebrecht]
*) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
to avoid "discard const" warnings. [Ralf S. Engelschall]
*) If a specific handler is set for a file yet the request still
ends up being handled by the default handler, log an error
message before handling it. This catches things such as trying
to use SSIs without mod_include enabled. [Marc Slemko]
*) Fix error logging for the startup case where ap_log_error() still uses
stderr as the target. Now the default log level is honored here, too.
[Ralf S. Engelschall]
*) PORT: Make sure some AWK's don't fail in src/Configure with "string too
long" errors when generating the MODULES entry for src/Makefile
[Ben Hyde, Ralf S. Engelschall]
*) Make sure src/Configure doesn't complain about the old directory
/usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
Changes with Apache 1.3b6
*) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
*) Adding DSO support for the HP/UX platform by emulating the dlopen-style
interface via the similar but proprietary HP/UX shl_xxx-style system
calls. [Ralf S. Engelschall]
*) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
APACI Makefile.tmpl "install" target more robust for sensible UnixWare
Make. [Ralf S. Engelschall]
*) ++++ THE BIG SYMBOL RENAMING ++++
To avoid symbol clashes with third-party code compiled into the server,
we globally applied the prefix "ap_" to the following classes of
functions:
- Apache provided general functions (e.g., ap_cpystrn)
- Public API functions (e.g., palloc, bgets)
- Private functions which we can't make static (because of
cross-object usage) but should be (e.g., new_connection)
For backward source compatibility a new header file named compat.h was
created which provides defines for the old symbol names and can be used
by third-party module authors.
[The Apache Group]
*) Added dynamic shared object (DSO) support for SVR4-derivates: The
problem under SVR4 is that there is no command flag to force the linker
to export the global symbols of the httpd executable therewith they are
available to the DSO's. Instead of problematic hacks like creating a
dummy.so file (containing dummy references to all global symbols) the
httpd binary is linked against, we use a clean trick stolen from Perl 5:
Placing the Apache core code itself into a DSO library named libhttpd.so.
This way the global symbols _HAVE_ to be exported and thus are available
to any manually loaded DSO's under runtime. To reduce the impact to the
user to null we go even further and create a stub httpd executable which
automatically keeps track of the DSO library loading itself and thus
hides the complete mechanism from the user. Although the generation of
this DSO library is automatically triggered for platforms which
essentially need it (mostly all SVR4-derivates) it can be also enabled
manually via the Rule SHARED_CORE. This can be interesting in the future
where we perhaps exploit this libhttpd.so mechanism for providing nifty
features like graceful upgrades, or whatever.
[Ralf S. Engelschall, Martin Kraemer]
*) Build the libraries before building the rest of the tools. [Ben Hyde]
*) Add "distclean" target to src/-Makefiles to provide "make distclean" also
inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
conventions while "clean" removes only stuff created by "all" targets,
"distclean" additionally removes the stuff from the configuration
process. This way "make distclean" (hence the name) provides a fresh
source tree as it was for distribution.
[Ralf S. Engelschall]
*) Allow top-level (APACI) Makefile to break on build errors
the same way the src/ subtree Makefiles breaks on them by replacing the
initial APACI sed-subdir-display-kludge with a more clean
variable-passing-solution: variable SDP can optionally hold the subdir
prefix which is consistently used for displaying the subdir movement.
This way even the top-level Makefile can stop correctly on errors as the
user expects. [Ralf S. Engelschall]
*) Fixed ordering of argument checks for RewriteBase directive.
[Todd Eigenschink <eigenstr@mixi.net>] PR#2045
*) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
indicating that a module is being compiled for dynamic loading. Also
remove #define IS_MODULE from modules and add SHARED_MODULE define
to the mak/dsp files. [Alexei Kosut]
*) Reduce logging level of "normal" warning messages to APLOG_INFO,
since we are now logging APLOG_WARNING by default. [Roy Fielding]
*) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
*) Add documentation file and src/Configuration.tmpl entry for the
experimental mod_mmap_static module. Because although it is and marked as
an experimental one it is distributed and thus should be documented and
prepared for configuration the same way as all others modules.
[Ralf S. Engelschall]
*) Add query (-q) option to apxs support tool to be able to manually query
specific settings from apxs. This is needed for instance when you
manually want to access Apache's header files and you need to assemble
the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
[Ralf S. Engelschall]
*) Now src/Configure uses a fallback strategy for the shared object support
on platforms where no explicit information is available: If a Perl
installation exists we ask it about its shared object support and if it's
the dlopen-style one we shamelessly guess the compiler and linker flags
for creating shared objects from Perls knowledge. Of course, the user is
warning about what we are doing and informed that he should send us
the guessed flags when they work. [Ralf S. Engelschall]
*) Provide APACI --without-support option to be able to disable the build
and installation of the support tools from the src/support/ area.
Although its useful to have these installed per default we should provide
a way to compile and install without them for backward-compatibility.
[Ralf S. Engelschall]
*) Add of the new APache eXtenSion (apxs) support tool for building and
installing modules into an _already installed_ Apache package through the
dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
this approach actually doesn't need the Apache source tree. The
(APACI-installed) server package is enough, because this now includes the
Apache C header files (PREFIX/include) and the new APXS tool
(SBINDIR/apxs). The intend is to provide a handy tool for third-party
module authors to build their Apache modules _OUTSIDE_ the Apache source
tree while avoiding them to fiddle around with the totally platform
dependend way of compiling DSO files. The tool supports all ranges of
modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
on-the-fly generate a minimalistic Makefile and sample module for the
first step to provide both a quick success event and to demonstrate the
APXS mechanism to module authors. [Ralf S. Engelschall]
*) Fix core dumps in use of CONNECT in proxy.
[Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
*) Modify the log directives in httpd.conf-dist files to use CustomLog
so that users have examples of how CustomLog can be used.
[Lars Eilebrecht]
*) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
the Apache distribution tree. Until Apache 1.3 there was no real
out-of-the-box batch-capable build and installation procedure for the
complete Apache package. This is now provided by a top-level "configure"
script and a corresponding top-level "Makefile.tmpl" file. The goal is
to provide a GNU Autoconf-style frontend which is capable to both drive
the old src/Configure stuff in batch and additionally installs the
package with a GNU-conforming directory layout. Any options from the old
configuration scheme are available plus a lot of new options for flexibly
customizing Apache. [Ralf S. Engelschall]
*) The floating point ap_snprintf code wasn't threadsafe.

*) BUG: Configure was using TCC and CC inconsistently. Make sure
Configure knows which CC we are using. [Jim Jagielski]
*) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
was defined in a parent directory. [Lars Eilebrecht]
*) API: ap_snprintf() code mutated into ap_vformatter(), which is
a generic printf-style routine that can call arbitrary output
routines. Use this to replace http_bprintf.c. Add new routines
psprintf(), pvsprintf() which allocate the exact amount of memory
required for a string from a pool. Use psprintf() to clean up
various bits of code which used ap_snprintf()/pstrdup().
[Dean Gaudet]
*) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
ap_snprintf() has different semantics and formatting codes than
snprintf(). [Dean Gaudet]
*) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
is necessary on at least Solaris where the /etc/rc?.d scripts
are run with these signals ignored, and "SIG_IGN" settings are
maintained across exec().
[Rein Tollevik <reint@sys.sol.no>] PR#2009

*) Allow %2F in two situations: 1) it is in the query part of the URI,
therefore not exposed to %2F -> '/' translations and 2) the request
is a proxy request, so we're not dealing with a local resource anyway.
Without this, the proxy would fail to work for any URL's with
%2f in them (occurs quite often in
http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]

*) Reanimated the (still undocumented) proxy receive buffer size directive:
Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old

suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
and per default compiled support programs have manual pages - just to
document our stuff a little bit more and to be able to do really
Unix-like installations ;-) [Ralf S. Engelschall]
*) Major cleanups to the Configure script to make it and its generated
Makefiles again readable and maintainable: add SRCDIR option, removed
INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
generated sections, consequently added Makefile headers with inheritance
information, added subdir movement messages for easier following where
the build process currently stays (more verbose then standard Make, less
verbose than GNU make), same style to comments in the Configure script,
added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
*) Add the new ApacheBench program "ab" to src/support/: This is derived
from the ZeusBench benchmarking program and can be used to determine the
response performance of an Apache installation. This version is
officially licensed with Zeus Technology, Ltd. See the license agreement

*) Making the hard-coded cross-module function call mime_find_ct() (from
mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
checking is really called even for proxy requests except for URLs with
HTTP schemes (because there we can optimize by not running the type
checking hooks due to the fact that the proxy gets the MIME Content-type
from the remote host later). This change cleans up mod_mime by removing
the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
especially unbundles mod_proxy and mod_mime. This way they both now can
be compiled as shared objects and are no longer tied together.
[Ralf S. Engelschall]

*) Add check to the "Port" directive to make sure the specified
port is in the appropriate range. [Ben Hyde]
*) Performance improvements to invoke_handler().
[Dmitry Khrustalev <dima@bog.msu.su>]
*) Added support for building shared objects even for library-style modules
(which are built from more than one object file). This now provides the
ability to build mod_proxy as a shared object module. Additionally
modules like mod_example are now also supported for shared object
building because the generated Makefiles now no longer assume there is at
least one statically linked module. [Ralf S. Engelschall]
*) API: Clarify usage of content_type, handler, content_encoding,
content_language and content_languages fields in request_rec. They
must always be lowercased; and the strings pointed to shouldn't
be modified (you must copy them to modify them). Fix a few bugs
related to this. [Dean Gaudet]
*) API: Clarification: except for RAW_ARGS, all command handlers can
treat the char * parameters as permanent, and modifiable. There
is no need to pstrdup() them. Clean up some needless pstrdup().
[Dean Gaudet]
*) Now mod_so keeps track of which module shared objects with which names
are loaded and thus avoids multiple loading and unloading and irritating
error_log messages. [Ralf S. Engelschall]
*) Prior to the existence of mod_setenv it was necessary to tweak the TZ
environment variable in the apache core. But that tweaking interferes
with mod_setenv. So don't tweak if the user has specified an explicit

*) rputs() did not calculate r->sent_bodyct properly.
[Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
*) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
name, or left unset if this value is unavailable. Apache was setting
it to the IP address when unavailable.
[Tony Finch <fanf@demon.net>] PR#1925
*) Various improvements to the configuration and build support for compiling
modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
OSF1 support with GCC and vendor compilers was added. This way shared
object support is now provided out-of-the-box for FreeBSD, Linux,
Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
[Ralf S. Engelschall]
*) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
and USE_OS2_SCOREBOARD. [Dean Gaudet]
*) Fix one more special locking problem for RewriteMap programs in
mod_rewrite: According to the documentation of flock(), "Locks are on
files, not file descriptors. That is, file descriptors duplicated
through dup(2) or fork(2) do not result in multiple instances of a lock,
but rather multiple references to a single lock. If a process holding a
lock on a file forks and the child explicitly unlocks the file, the
parent will lose its lock.". To overcome this we have to make sure the
RewriteLock file is opened _AFTER_ the childs were spawned which is now
the case by opening it in the child_init instead of the module_init API
hook. [Ralf S. Engelschall] PR#1029
*) Change to Location and LocationMatch semantics. LocationMatch no
longer lets a single slash match multiple adjacent slashes in the
URL. This change is for consistency with RewriteRule and
AliasMatch. Multiple slashes have meaning in URLs that they do
not have in (some) filesystems. Location on the other hand can
be considered a shorthand for a more complicated regex, and it
does match multiple slashes with a single slash -- which is
also consistent with the Alias directive.
[Dean Gaudet] related PR#1440
*) Fix bug with mod_mime_magic causing certain files, including files
of length 0, to result in no response from the server.
[Dean Gaudet]
*) The Configure script now generates src/include/ap_config.h which
contains the set of defines used when Apache is compiled on a platform.
This file can then be included by external modules before including
any Apache header files in case they are being built separately from
Apache. Along with this change, a couple of minor changes were
made to make Apache's #defines coexist peacefully with any autoconf
defines an external module might have. [Rasmus Lerdorf]
*) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
but without any RewriteXXXXX directives. Here mod_rewrite is given no
chance by the API to initialize its per-server configuration and thus
receives the wrong one from the main server. This is now avoided by
remembering the server together with the config structure while
configuring and later assuming there is no config when we see a
difference between the remembered server and the one calling us.
[Ralf S. Engelschall] PR#1790
*) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
is automatically disabled under configure time when the dbm_xxx functions
are not available. Second, two heavy source code errors in the DBM
support code were fixed. This makes DBM RewriteMap's usable again after
a long time of brokenness. [Ralf S. Engelschall] PR#1696
*) Now all configuration files support Unix-style line-continuation via
the trailing backslash ("\") character. This enables us to write down
complex or just very long directives in a more readable way. The
backslash character has to be really the last character before the
newline and it has not been prefixed by another (escaping) backslash.

[Ken Coar] PR#1448
*) WIN32: Preserve trailing slash in canonical path (and hence
in PATH_INFO). [Paul Sutton, Ben Laurie]
*) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
depending on the rev of Solaris and what mixture of modules
are in use. So it has been disabled, and Solaris is back to
using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
up static content only servers. Or it may fail unpredictably.
[Dean Gaudet] PR#1779, 1854, 1904
*) mod_test_util_uri.c created which tests the logic in util_uri.c.
[Dean Gaudet]
*) API: Rewrite of absoluteURI handling, and in particular how
absoluteURIs match vhosts. Unless a request is a proxy request, a
"http://host" url is treated as if a similar "Host:" header had been
supplied. This change was made to support future HTTP/1.x protocols
which may require clients to send absoluteURIs for all requests.
In order to achieve this change subtle changes were made to the API. In a
request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
that the unmodified uri can be retrieved easily. r->proxyreq is not set
by the core, modules must set it during the post_read_request or
translate_names phase.
Plus changes to the virtualhost test suite for absoluteURI testing.
This fixes several bugs with the proxy proxying requests to vhosts
managed by the same httpd.
[Dean Gaudet]
*) API: Cleanup of code in http_vhost.c, and remove vhost matching
code from mod_rewrite. The vhost matching is now performed by a
globally available function matches_request_vhost(). [Dean Gaudet]

side-effect users can list multiple ServerAlias directives
and they're all considered.

*) Add the `%a' construct to LogFormat and CustomLog to log the client IP
address. [Todd Eigenschink <eigenstr@mixi.net>] PR#1885
*) API: A new source module main/util_uri.c; It contains a routine
parse_uri_components() and friends which breaks a URI into its component
parts. These parts are stored in a uri_components structure called
parsed_uri within each request_rec, and are available to all modules.
Additionally, an unparse routine is supplied which re-assembles the URI
components back to an URI, optionally hiding the username:password@ part
from ftp proxy requests, and other useful routines. Within the structure,
you find on a ready-for-use basis:
scheme; /* scheme ("http"/"ftp"/...) */
hostinfo; /* combined [user[:password]@]host[:port] */
user; /* user name, as in http://user:passwd@host:port/ */
password; /* password, as in http://user:passwd@host:port/ */
hostname; /* hostname from URI (or from Host: header) */
port_str; /* port string (integer representation is in "port") */
path; /* the request path (or "/" if only scheme://host was given) */
query; /* Everything after a '?' in the path, if present */
fragment; /* Trailing "#fragment" string, if present */
This is meant to serve as the platform for *BIG* savings in
code complexity for the proxy module (and maybe the vhost logic).
[Martin Kraemer]
*) Make all possible meta-construct expansions ($N, %N, %{NAME} and
${map:key}) available for all location where a string is created in
mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
possible expansions are consequently usable at all string creation
locations. [Ralf S. Engelschall]
*) Fix initialization of RewriteLogLevel (default now is 0 as documented
and not 1) and the per-virtual-server merging of directives. Now all
directives except `RewriteEngine' and `RewriteOption' are either
completely overridden (default) or completely inherited (when
`RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

*) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
(like SunOS and FreeBSD) which don't accept the locking of pipes
directly. A new directive RewriteLock is introduced which can be used to
setup a separate locking file which then is used for synchronization.

[Ralf S. Engelschall]
*) The mod_setenvif BrowserMatch backwards compatibility command did not
work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
*) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
type but with a special post-processing for the looked-up value: It
parses it into alternatives according to `|' chars and then only one
particular alternative is chosen randomly (this is an essential
functionality needed for balancing between backend-servers when using
Apache as a Reverse Proxy. The looked up value here is a list of
servers). Second, `int' with the built-in maps named `tolower' and
`toupper' which can be used to map URL parts to a fixed case (this is an
essential feature to fix the case of server names when doing mass
virtual-hosting with the help of mod_rewrite instead of using
<VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
Jay Soffian <jay@cimedia.com>] PR#1631
*) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
This directive lets Apache adjust the URL in Location-headers on HTTP
redirect responses sent by the remote server. This way the virtually
mapped area is no longer left on redirects and thus by-passed which is
especially essential when running Apache as a reverse proxy.

*) MiNT port update. [Jan Paul Schmidt]
*) HTTP/1.1 requires x-gzip and gzip encodings be treated
equivalent, similarly for x-compress and compress. Apache
now ignores a leading x- when comparing encodings. It also
preserves the encoding the client requests (for example if
it requests x-gzip, then Apache will respond with x-gzip
in the Content-Encoding header).

get_server_port().

PR#315, 459, 485, 1433
*) Yet another rearrangement of the source tree.. now all the common
header files are in the src/include directory. The -Imain -Iap
references in Makefiles have been changed to the simpler -Iinclude
instead. In addition to simplifying the build a little bit, this
also makes it clear when a module is referencing something in a
other than kosher manner (e.g., the proxy including mod_mime.h).
Module-private header files (the proxy, mod_mime, the regex library,
and mod_rewrite) have not been moved to src/include; nor have
the OS-abstraction files. [Ken Coar]
*) Fix a bug where r->hostname didn't have the :port stripped

*) Tweaked the headers_out table size, and the subprocess_env

MAKE_TABLE_PROFILE which can help discover make_table()

[Dean Gaudet]
*) Options and AllowOverride weren't properly merging in the main
server setting inside vhosts (only an issue when you have no
<Directory> or other section containing an Options that affects
a request). Options +foo or -foo in the main_server wouldn't
affect the main_server's lookup defaults. [Dean Gaudet]
*) Variable 'cwd' was being used pointlessly before being set.
[Ken Coar] PR#1738
*) r->allowed handling cleaned up in the standard modules.
[Dean Gaudet]
*) Some case-sensitivity issues cleaned up to be consistent with
RFC2068. [Dean Gaudet]
*) SIGURG doesn't exist everywhere.
[Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
*) mod_unique_id was erroneously generating a second unique id when
an internal redirect occured. Such redirects occur, for example,
when processing a DirectoryIndex match. [Dean Gaudet]
*) API: table_add, table_merge, and table_set include implicit pstrdup()
of the key and value. But in many cases this is not required
because the key/value is a constant, or the value has been built
by pstrcat() or other similar means. New routines table_addn,
table_mergen, and table_setn have been added to the API, these
routines do not pstrdup() their arguments. The core code and
standard modules were changed to take advantage of these routines.
The resulting server is up to 20% faster in some situations.
Note that it is easy to get code subtly wrong if you pass a key/value
which is in a pool other than the pool of the table. The only
safe thing to do is to pass key/values which are in the pool of
the table, or in one of the ancestors of the pool of the table.
i.e. if the table is part of a subrequest, a value from the main
request's pool is OK since the subrequest pool is a sub_pool of the
main request's pool (and therefore has a lifespan at most as long as
the main pool). There is debugging code which can detect improper
usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
[Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
*) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
which don't exist on disk more gracefully; handles vhosts properly.
Update documentation to reflect the code -- if there's no
MimeMagicFile directive then the module is not enabled.
[Dean Gaudet]
*) PORT: Some older *nix dialects cannot automatically start scripts
which begin with a #! interpreter line (the shell starts the scripts
appropriately on these platforms). Apache now supports starting of
"hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
[Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)

*) API: "typedef array_header table" removed from alloc.h, folks should
have been writing to use table as if it were an opaque type, but even
some standard modules got this wrong. By changing the definition
to "typedef struct table table" module authors will receive compile
time warnings that they're doing the wrong thing. This change
facilitates future changes with more sophisticated table
structures. Specifically, module authors should be using table_elts()
to get access to an array_header * for the table. [Dean Gaudet]
*) API: Renamed new_connection() to avoid namespace collision with LDAP
library routines. [Ken Coar, Rasmus Lerdorf]
*) WIN32: mod_speling is now available on the Win32 platform.
[Marc Slemko]
*) For clarity the following compile time definition was changed:
SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
and not be a general notice that the OS has mmap(). Now the
HAVE_MMAP/SHMGET #defines strictly are informational that the
OS has that method of shared memory; the type to use for
the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
and USE_SHMGET_SCOREBOARD). This allows outside modules to
determine if shared memory is available and allows Apache
to determine the best method to use for the scoreboard.

*) suexec errors now include the errno/description. [Marc Slemko] PR#1543
*) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
The choice of flock vs. fcntl was made based on timings which showed that
even on non-NFS, non-exported filesystems fcntl() was an order of
magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
that single socket users will see no difference. [Dean Gaudet] PR#467
*) "File does not exist" error message was erroneously including the
errno. [Marc Slemko]
*) Improve the warning message generated when a client drops the

*) Defining GPROF will disable profiling in the parent and enable it
in the children. If you're profiling under Linux this is pretty much
necessary because SIGPROF is lost across a fork(). [Dean Gaudet]

purposes caused some compilers heartburn without adding any
significant value, so they've been removed. [Ken Coar]
*) The src/main/*.h header files have had #ifndef wrappers added to
insulate them against duplicate calls if they get included through
multiple paths (e.g., in .c files as well as other .h files).
[Ken Coar]
*) The libap routines now have a header file for their prototypes,
src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]

*) The bputc() macro was not properly integrated with the chunking
code; in many cases modules using bputc() could cause completely
bogus chunked output. (Typically this will show up as problems
with Internet Explorer 4.0 reading a page, but other browsers
having no problem.) [Dean Gaudet]
*) Create LARGE_WRITE_THRESHOLD define which determines how many
bytes have to be supplied to bwrite() before it will consider
doing a writev() to assemble multiple buffers in one system
call. This is critical for modules such as mod_include,
mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
strings in some cases. The result would be extra effort
setting up writev(), and in many cases extra effort building
chunks. The default is 31, it can be overriden at compile
time. [Dean Gaudet]

*) It was necessary to distinguish between resources which are
allocated in the parent, for cleanup in the parent, and resources
which are allocated in each child, for cleanup in each child.
A new pool was created which is passed to the module child_init

cleanups there. This fixes a bug with reliable piped logs.
[Dean Gaudet]

*) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
Now the rewriting engine (the heart of mod_rewrite) is organized more
straight-forward, first time well documented and reduced to the really
essential parts. All redundant cases were stripped off and processing now
is the same for both per-server and per-directory context with only a
minimum difference (the prefix stripping in per-dir context). As a
side-effect some subtle restrictions and two recently discovered problems
are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
context and restrictions on the substitution URL on redirects.
Additionally some minor source cleanups were done.

Changes with Apache 1.3b2 (there is no 1.3b1)
*) TestCompile was not passing $LIBS [Dean Gaudet]
*) Makefile.tmpl was not using $CFLAGS in the link phase.
[Martin Kraemer]
*) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
rudimentary memory debugger which can be used on live servers with
low impact -- it sets all allocated and freed memory bytes to 0xa5.
Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
and free() for each object. This is far more expensive and should
only be used for testing with tools such as Electric Fence and
Purify. See main/alloc.c for more details. [Dean Gaudet]
*) Configure uses a sh trap and didn't set its exitcode properly.
[Dean Gaudet] PR#1159
*) Yet another vhost revamp. Add the NameVirtualHost directive which
explicitly lists the ip:port pairs that are to be used for name-vhosts.
From a given ip:port, regardless what the Host: header is, you can
only reach the vhosts defined on that ip:port. The precedence of
vhosts was reversed to match other precedences in the config --
the earlier vhosts override the later vhosts. All vhost matching was
moved into http_vhost.[ch]. [Dean Gaudet]
*) ap_inline can be used to force inlining. GNUC __attribute__() can
be used for whatever reason is appropriate (i.e. format() warnings
for printf style functions). Both are enabled only with
gcc >= 2.7.x (so that we have fewer support issues with older
versions). [Dean Gaudet]
*) Fix support for Proxy Authentication (we were testing the response
status too early). [Marc Slemko]
*) CoreDumpDirectory directive directs where the core file is
written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
received. [Marc Slemko, Dean Gaudet]
*) PORT: Support for Atari MINT.
[Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
*) When booting, apache will now detach itself from stdin, stdout,
and stderr. stderr will not be detached until after the config
files have been read so you will be able to see initial error
messages. After that all errors are logged in the error_log.
This makes it more convenient to start apache via rsh, ssh,
or crontabs. [Dean Gaudet] PR#523
*) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
Also removed the auto-generated link to www.apache.org that was the
source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
*) send_fb would not detect aborted connections in some situations.

*) mod_imap should only handle GET methods. [Jay Bloodworth]
*) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
*) mod_autoindex improperly counted &escapes; as more than one
character in the description. It also improperly truncated
descriptions that were exactly the maximum length.
[Martin Kraemer]
*) RedirectMatch was not properly escaping the result (PR#1155). Also
"RedirectMatch /advertiser/(.*) $1" is now permitted.
[Dean Gaudet]
*) mod_include now uses symbolic names to check for request success
and return HTTP errors, and correctly handles all types of
redirections (previously it only did temporary redirect correctly).
[Ken Coar, Roy Fielding]
*) mod_userdir was modifying r->finfo in cases where it wasn't setting
r->filename. Since those two are meant to be in sync with each other
this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
*) PORT: Support Unisys SVR4, whose uname returns mostly useless data.

[Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
*) Fixed error in proxy_util.c when looping through multiple host IP
addresses. [Lars Eilebrecht] PR#974
*) If BUFFERED_LOGS is defined then mod_log_config will do atomic
buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
bytes before writing, but it will never split a log entry across a
buffer boundary. [Dean Gaudet]
*) API: the short_score record has been split into two pieces, one which
the parent writes on, and one which the child writes on. As part of
this change the get_scoreboard_info() function was removed, and
scoreboard_image was exported. This change fixes a race condition
in file based scoreboard systems, and speeds up changes involving the
scoreboard in earlier 1.3 development. [Dean Gaudet]
*) API: New register_other_child() API (see http_main.h) which allows
modules to register children with the parent for maintenance. It
is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
*) API: New piped_log API (see http_log.h) which implements piped logs,
and will use register_other_child to implement reliable piped logs
when it is available. The reliable piped logs part can be disabled
by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
logs is only available on Unix. [Dean Gaudet]
*) API: set_last_modified() broken into set_last_modified(), set_etag(), and
meets_conditions(). This allows conditional HTTP selection to be
handled separately from the storing of the header fields, and provides
the ability for CGIs to set their own ETags for conditional checking.
[Ken Coar, Roy Fielding] PR#895
*) Changes to mod_log_config to allow naming of format strings.
Format nicknames are defined with "LogFormat fmt nickname", and can
be used with "LogFormat nickname" and "CustomLog logtarget nickname".
[Ken Coar]
*) New module, "mod_speling", which can help find files even when
the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
*) API: New function child_terminate() triggers the child process to

*) *Really* disable all mod_rewrite operations if the engine is off.
Some things (like RewriteMaps) were checked/performed even if they

*) Implement a new timer scheme which eliminates the need to call alarm() all
the time. Instead a counter in the scoreboard for each child is used to
show when the child has made forward progress. The parent samples this
counter every scoreboard maintenance cycle, and issues SIGALRM if no
progress has been made in the timeout period. This reduces the static
request best-case syscall count to 22 from 29. This scheme is only
used by systems with memory-based scoreboards. [Dean Gaudet]
*) The proxy now properly handles CONNECT requests which are sent
to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
*) A script called apachectl has been added to the support
directory. This script allows you to do things such as
"apachectl start" and "apachectl restart" from the command
line. [Marc Slemko]
*) Modules and core routines are now put into libraries, which
simplifies the link line tremendously (among other advantages).
[Paul Sutton]
*) Some of the MD5 names defined in Apache have been renamed to have
an `ap_' prefix to avoid conflicts with routines supplied by
external libraries. [Ken Coar]
*) Removal of mod_auth_msql.c from the distribution. There are many
other options for databases today. Rather than offer one option,
offer none at this time. mod_auth_msql and other SQL database
authentication modules can be found at the Apache Module Registry.
http://modules.apache.org/ It would be nice to offer a generic
mod_auth_sql option in the near future.
*) PORT: BeOS support added [Alexei Kosut]
*) Configure no longer accepts the -make option, since it creates
Makefile on the fly based on Makefile.tmpl and Configuration.
*) Apache now gracefully shuts down when it receives a SIGTERM, instead
of forcibly killing off all its processes and exiting without
cleaning up. [Alexei Kosut]
*) API: A new field in the request_rec, r->mtime, has been added to
avoid gratuitous parsing of date strings. It is intended to hold
the last-modified date of the resource (if applicable). An
update_mtime() routine has also been added to advance it if
appropriate. [Roy Fielding, Ken Coar]
*) SECURITY: If a htaccess file can not be read due to bad permissions,
deny access to the directory with a HTTP_FORBIDDEN. The previous
behavior was to ignore the htaccess file if it could not be read.
This change may make some setups with unreadable htaccess files
stop working. [Marc Slemko] PR#817
*) Add aplog_error() providing a mechanism to define levels of
verbosity to the server error logging. This addition also provides
the ability to log errors using syslogd. Error logging is configurable
on a per-server basis using the LogLevel directive. Conversion
of log_*() in progress. [Randy Terbush]
*) Further enhance aplog_error() to not log filename, line number, and
errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
*) WIN32: Canonicalise filenames under Win32. Short filenames are
converted to long ones. Backslashes are converted to forward
slashes. Case is converted to lower. Parts of URLs that do not
correspond to files are left completely alone. [Ben Laurie]
*) PORT: 2 new OSs added to the list of ports:
Encore's UMAX V: Arieh Markel <amarkel@encore.com>
Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
*) Add the server version (SERVER_VERSION macro) to the "server
configured and running" entry in the error_log. Also build an
object file at link-time that contains the current time
(SERVER_BUILT global const char[]), and include that in the
message. [Ken Coar]
*) Set r->headers_out when sending responses from the proxy.
This fixes things such as the logging of headers sent from
the proxy. [Marc Slemko] PR#659
*) support/httpd_monitor is no longer distributed because the
scoreboard should not be file based if at all possible. Use
mod_status to see current server snapshot.
*) (set_file_slot): New function, allowing auth directives to be
independent of the server root, so the server documents can be
moved to a different directory or machine more easily.
[David J. MacKenzie]
*) If no TransferLog is given explicitly, decline
to log. This supports coexistence with other logging modules,
such as the custom one that UUNET uses. [David J. MacKenzie]
*) Check for titles in server-parsed HTML files.
Ignore leading newlines and returns in titles. The old behavior
of replacing a newline after <title> with a space causes the
title to be misaligned in the listing. [David J. MacKenzie]
*) Change mod_cern_meta to be configurable on a per-directory basis.
[David J. MacKenzie]
*) Add 'Include' directive to allow inclusion of configuration
files within configuration files. [Randy Terbush]
*) Proxy errors on connect() are logged to the error_log (nothing
new); now they include the IP address and port that failed
(*that's* new). [Ken Coar, Marc Slemko] PR#352
*) Various architectures now define USE_MMAP_FILES which causes
the server to use mmap() for static files. There are two
compile-time tunables MMAP_THRESHOLD (minimum number of bytes
required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
number of bytes written in one cycle from a single mmap()d object,
default 32768). [Dean Gaudet]
*) API: Added post_read_request API phase which is run right after reading
the request from a client, or right after an internal redirect. It is
useful for modules setting environment variables that depend only on
the headers/contents of the request. It does not run during subrequests
because subrequests inherit pretty much everything from the main
request. [Dean Gaudet]
*) Added mod_unique_id which is used to generate a unique identifier for
each hit, available in the environment variable UNIQUE_ID.
[Dean Gaudet]
*) init_modules is now called after the error logs have been opened. This
allows modules to emit information messages into the error logs.
[Dean Gaudet]
*) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
information for case where proxy module is not available. [Marc Slemko]
*) PORT: Apache has need for mutexes to serialize its children around
accept. In prior versions either fcntl file locking or flock file
locking were used. The method is chosen by the definition of
USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
and FLOCK for flock(). New options have been added:
- SYSVSEM to use System V style semaphores
- PTHREAD to use POSIX threads (appears to work on Solaris only)
- USLOCK to use IRIX uslock
Based on timing various techniques, the following changes were made
to the defaults:
- Linux 2.x uses flock instead of fcntl
- Solaris 2.x uses pthreads
- IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
[Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
Martijn Koster <m.koster@pobox.com>]
*) PORT: The semantics of accept/select make it very desirable to use
mutexes to serialize accept when multiple Listens are in use. But
in the case where only a single socket is open it is sometimes
redundant to serialize accept(). Not all unixes do a good job with
potentially dozens of children blocked on accept() on the same
socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
the server will avoid serialization when listening on only one socket,
and use serialization when listening on multiple sockets.
[Dean Gaudet] PR#467
*) Configure changes: TestLib replaced by TestCompile, which has
some additional capability (such as doing a sanity check of
the compiler and flags selected); the version of Solaris is now
available via the #define value of SOLARIS2; IRIX n32bit libs
now supported and selectable by new Configuration Rule: IRIXN32;
We no longer default to -O2 optimization. [Jim Jagielski]
*) Updated Configure: Configuration now uses AddModule to specify
module source or binary file location, relative to src directory.
Modules can be dropped into modules/extra, or in their own
directory, and modules can come with a Makefile or Configure can
create one. Modules can add compiler or library information to
generated Makefiles. [Paul Sutton]
*) Source core re-organisation: distributed modules are now in
modules/standard. All other source code is in main. OS-specific
code is in os/{unix,emx,win32} directories. [Paul Sutton]
*) mod_browser has been removed, since it's replaced by mod_setenvif.
[Ken Coar]
*) Fix another long-standing bug in sub_req_lookup_file where it would
happily skip past access checks on subdirectories looked up with
relative paths. (It's used by mod_dir, mod_negotiation,
and mod_include.) [Dean Gaudet]
*) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
N is the number of <Directory> sections, and M is the number of
components in the filename of an object.
To achieve this optimization the following config changes were made:
- Wildcards (* and ?, not the regex forms) in <Directory>s,
<Files>s, and <Location>s now treat a slash as a special
character. For example "/home/*/public_html" previously would
match "/home/a/andrew/public_html", now it only matches things
like "/home/bob/public_html". This mimics /bin/sh behaviour.
- It's possible now to use [] wildcarding in <Directory>, <Files>
or <Location>.
- Regex <Directory>s are applied after all non-regex <Directory>s.
[Dean Gaudet]
*) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
and corrupted paths. [Dean Gaudet]
*) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
First the grouped parts of RewriteRule pattern matches (parenthesis!) can
be accessed now via backreferences $1..$9 in RewriteConds test-against
strings in addition to RewriteRules subst string. Second the grouped
parts of RewriteCond pattern matches (parenthesis!) can be accessed now
via backreferences %1..%9 both in following RewriteCond test-against
strings and RewriteRules subst string. This provides maximum flexibility
through the use of backreferences.
Additionally the rewriting engine was cleaned up by putting common
code to the new expand_backrefs_inbuffer() function.
[Ralf S. Engelschall]
*) When merging the main server's <Directory> and <Location> sections into
a vhost, put the main server's first and the vhost's second. Otherwise
the vhost can't override the main server. [Dean Gaudet] PR#717
*) The <Directory> code would merge and re-merge the same section after
a match was found, possibly causing problems with some modules.
[Dean Gaudet]
*) ip-based vhosts are stored and queried using a hashing function, which
has been shown to improve performance on servers with many ip-vhosts.
Some other changes had to be made to accommodate this:
- the * address for vhosts now behaves like _default_
- the matching process now is:
- match an ip-vhost directly via hash (possibly matches main
server)
- if that fails, just pretend it matched the main server
- if so far only the main server has been matched, perform
name-based lookups (ServerName, ServerAlias, ServerPath)
*only on name-based vhosts*
- if they fail, look for _default_ vhosts
[Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
*) dbmmanage overhaul:
- merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
- tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
- provide better seed for rand
- prompt for password as per getpass(3) (turn off echo, read from
/dev/tty, etc.)
- use "newstyle" crypt based on $Config{osname} ($^O)
- will not add a user if already in database, use new `update' command
instead
- added `check' command to check a users' password
- added `import' command to convert existing password text-files or
dbm files exported with `view'
- more descriptive usage, general cleanup, 'use strict' clean, etc.
[Doug MacEachern]
*) Added psocket() which is a pool form of socket(), various places within
the proxy weren't properly blocking alarms while registering the cleanup
for its sockets. bclose() now uses pclose() and pclosesocket(). There
was a bug where the client socket was being close()d twice due a still
registered cleanup. [Dean Gaudet]
*) A few cleanups were made to reduce time(), getpid(), and signal() calls.
[Dean Gaudet]
*) PORT: AIX >= 4.2 requires -lm due to libc changes.
[Jason Venner <jason@idiom.com>] PR#667
*) Enable ``=""'' for RewriteCond directives to match against
the empty string. This is the preferred way instead of ``^$''.
[Ralf S. Engelschall]
*) Fixed an infinite loop in mod_imap for references above the server root
[Dean Gaudet] PR#748
*) mod_proxy now has a ReceiveBufferSize directive, similar to
SendBufferSize, so that the TCP window can be set appropriately
for LFNs. [Phillip A. Prindeville]
*) mod_browser has been replaced by the more general mod_setenvif
(courtesy of Paul Sutton). BrowserMatch* directives are still
available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
UnSetEnvIfZero directives. [Ken Coar]
*) "HostnameLookups double" forces double-reverse DNS to succeed in
order for remote_host to be set (for logging, or for the env var
REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
[Dean Gaudet]
*) mod_access overhaul:
- Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
and cidr syntax (i.e. 10.1.0.0/16). PR#762
- Critical path was sped up by pre-computing a few things at config time.
- The undocumented syntax "allow user-agents" was removed,
the replacement is "allow from env=foobar" combined with mod_browser.
- When used with hostnames it now forces a double-reverse lookup
no matter what the directory settings are. This double-reverse
doesn't affect any of the other routines that use the remote
hostname. In particular it's still passed to CGIs and the log
without the double-reverse check. Related PR#860.
[Dean Gaudet]
*) When a large bwrite() occurs (larger than the internal buffer size),
while there is already something in the buffer, apache will combine
the large write and the buffer into a single writev(). (This is
in anticipation of using mmap() for reading files.)
[Dean Gaudet]
*) In obscure cases where a partial socket write occurred while chunking,
Apache would omit the chunk header/footer on the next block. Cleaned
up other bugs/inconsistencies in error conditions in buff.c. Fixed
a bug where a long pause in DNS lookups could cause the last packet
of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
*) API: Added child_exit function to module structure. This is called
once per "heavy-weight process" just before a server child exit()'s
e.g. when max_requests_per_child is reached, etc.
[Doug MacEachern, Dean Gaudet]
*) mod_include cleanup showed that handle_else was being used to handle
endif. It didn't cause problems, but it was cleaned up too.
[Howard Fear]
*) mod_cern_meta would attempt to find meta files for the directory itself
in some cases, but not in others. It now avoids it in all cases.
[Dean Gaudet]
*) mod_mime_magic would core dump if there was a decompression error.
[Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
*) PORT: some variants of DGUX require -lsocket -lnsl
[Alexander L Jones <alex@systems-options.co.uk>] PR#732
*) mod_autoindex now allows sorting of FancyIndexed directory listings
by the various fields (name, size, et cetera), either in ascending
or descending order. Just click on the column header. [Ken Coar]
*) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
CPUs like the Alpha. Apache still stores ints in pointers, but that's
the relatively safe direction. [Dean Gaudet] PR#344
*) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
[Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
*) child_main avoids an unneeded call to select() when there is only one
listening socket. [Dean Gaudet]
*) In the event that the server is starved for idle servers it will
spawn 1, then 2, then 4, ..., then 32 servers each second,
doubling each second. It'll also give a warning in the errorlog
since the most common reason for this is a poor StartServers
setting. The define MAX_SPAWN_RATE can be used to raise/lower
the maximum. [Dean Gaudet]
*) Apache now provides an effectively unbuffered connection for
CGI scripts. This means that data will be sent to the client
as soon as the CGI pauses or stops output; previously, Apache would
buffer the output up to a fixed buffer size before sending, which
could result in the user viewing an empty page until the CGI finished
or output a complete buffer. It is no longer necessary to use an
"nph-" CGI to get unbuffered output. Given that most CGIs are written
in a language that by default does buffering (e.g. perl) this
shouldn't have a detrimental effect on performance.
"nph-" CGIs, which formerly provided a direct socket to the client
without any server post-processing, were not fully compatible with
HTTP/1.1 or SSL support. As such they would have had to implement
the transport details, such as encryption or chunking, in order
to work properly in certain situations. Now, the only difference
between nph and non-nph scripts is "non-parsed headers".
[Dean Gaudet, Sameer Parekh, Roy Fielding]
*) If a BUFF is switched from buffered to unbuffered reading the first
bread() will return whatever remained in the buffer prior to the
switch. [Dean Gaudet]
Changes with Apache 1.3a1
*) Added another Configure helper script: TestLib. It determines
if a specified library exists. [Jim Jagielski]
*) PORT: Allow for use of n32bit libraries under IRIX 6.x
[derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
PR#721
*) PORT: Some architectures use size_t for various lengths in network
functions such as accept(), and getsockname(). The definition
NET_SIZE_T is used to control this. [Dean Gaudet]
*) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
*) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
[Igor N Kovalenko <infoh@mail.wplus.net>]
*) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
"downgrade-1.0" which causes Apache to pretend it received a 1.0.
[Dean Gaudet] related PR#875
*) API: Correct child_init() slot declaration from int to void, to
match the init() declaration. Update mod_example to use the new
hook. [Ken Coar]
*) added transport handle slot (t_handle) to the BUFF structure
[Doug MacEachern]
*) get_client_block() returns wrong length if policy is
REQUEST_CHUNKED_DECHUNK.
[Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815
*) Support the image map format of FrontPage. For example:
rect /url.hrm 10 20 30 40
["Chris O'Byrne" <obyrne@iol.ie>] PR#807
*) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
*) AddModuleInfo directive for mod_info which allows you to annotate
the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
*) Added NoProxy directive to avoid using ProxyRemote for selected
addresses. Added ProxyDomain directive to cause unqualified
names to be qualified by redirection.
[Martin Kraemer <Martin.Kraemer@mch.sni.de>]
*) Support Proxy Authentication, and don't pass the Proxy-Authorize
header to the remote host in the proxy. [Sameer Parekh and
Wallace]
*) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
URLs, fixed rewritelog(), fixed forced response code handling on
redirects from within .htaccess files, disabled pipe locking under
braindead SunOS 4.1.x, allow env variables to be set even on rules with
no substitution, bugfixed situations where HostnameLookups is off, made
mod_rewrite more thread-safe for NT port and fixed problem when creating
an empty query string via "xxx?".
This update also removes the copyright of Ralf S. Engelschall,
i.e. now mod_rewrite no longer has a shared copyright. Instead is is
exclusively copyrighted by the Apache Group now. This happened because
the author now has gifted mod_rewrite exclusively to the Apache Group and
no longer maintains an external version.
[Ralf S. Engelschall]
*) API: Added child_init function to module structure. This is called
once per "heavy-weight process" before any requests are handled.
See http_config.h for more details. [Dean Gaudet]
*) Anonymous_LogEmail was logging on each subrequest.
[Dean Gaudet] PR#421, 868
*) API: Added is_initial_req() which tests if the request being
processed is the initial request, or a subrequest.
[Doug MacEachern]
*) Extended SSI (mod_include) now handles additional relops for
string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
*) Configure fixed to correctly propagate user-selected options and
settings (such as CC and OPTIM) to Makefiles other than
src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
*) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
directory indices to start with the contents of the HeaderName file
if there is one. If there isn't one, the behaviour is unchanged.
[Ken Coar, Roy Fielding, Andrey A. Chernov]
*) WIN32: Modules can now be dynamically loaded DLLs using the
LoadModule/LoadFile directives. Note that module DLLs must be
compiled with the multithreaded DLL version of the runtime library.
[Alexei Kosut and Ben Laurie]
*) Automatic indexing removed from mod_dir and placed into mod_autoindex.
This allows the admin to completely remove automatic indexing
from the server, while still supporting the basic functions of
trailing-slash redirects and DirectoryIndex files. Note that if
you're carrying over an old Configuration file and you use directory
indexing then you'll want to add:
Module autoindex_module mod_autoindex.o
before mod_dir in your Configuration. [Dean Gaudet]
*) popendir/pclosedir created to properly protect directory scanning.
[Dean Gaudet] PR#525
*) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
[Alexei Kosut]
*) The AccessFileName directive can now take more than one filename.
["Lou D. Langholtz" <ldl@usi.utah.edu>]
*) The new mod_mime_magic can be used to "magically" determine the type
of a file if the extension is unknown. Based on the unix file(1)
command. [Ian Kluft <ikluft@cisco.com>]
*) We now determine and display the time spent processing a
request if desired. [Jim Jagielski]
*) mod_status: PID field of "dead" child slots no longer displays
main httpd process's PID. [Jim Jagielski]
*) Makefile.nt added - to build all the bits from the command line:
nmake -f Makefile.nt
Doesn't yet work properly. [Ben Laurie]
*) Default text of 404 error is now "Not Found" rather than the
potentially misleading "File Not Found". [Ken Coar]
*) CONFIG: "HostnameLookups" now defaults to off because it is far better
for the net if we require people that actually need this data to
enable it. [Linus Torvalds]
*) directory_walk() is an expensive function, keep a little more state to
avoid needless string counting. Add two new functions make_dirstr_parent
and make_dirstr_prefix which replace all existing uses of make_dirstr.
The new functions are a little less general than make_dirstr, but
work more efficiently (less memory, less string counting).
[Dean Gaudet]
*) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
to LDFLAGS) to avoid complications with lex rules in make files.
[Dean Gaudet] PR#372
*) run_method optimized to avoid needless scanning over NULLs in the
module list. [Dean Gaudet]
*) Revamp of (unix) scoreboard management code such that it avoids
unnecessary traversals of the scoreboard on each hit. This is
particularly important for high volume sites with a large
HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
httpd.h. [Dean Gaudet]
*) In configurations using multiple Listen statements it was possible for
busy sockets to starve other sockets of service. [Dean Gaudet]
*) Added hook so standalone_main can be replaced at compile time
(define STANDALONE_MAIN)
[Doug MacEachern]
*) Lowest-level read/write functions in buff.c will be replaced with
the SFIO library calls sfread/sfwrite if B_SFIO is defined at
compile time. The default sfio discipline will behave as apache
would without sfio compiled in.
[Doug MacEachern]
*) Enhance UserDir directive (mod_userdir) to accept a list of
usernames for the 'disable' keyword, and add 'enable user...' to
selectively *en*able userdirs if they're globally disabled.
[Ken Coar]
*) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
will work with Netscape dbm files. (dbmmanage will probably not
work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
*) Add a ListenBacklog directive to control the backlog parameter
passed to listen(). Also change the default to 511 from 512.
[Marc Slemko]
*) API: A new handler response DONE which informs apache that the
request has been handled and it can finish off quickly, similar to
how it handles errors. [Rob Hartill]
*) Turn off chunked encoding after sending terminating chunk/footer
so that we can't do it twice by accident. [Roy Fielding]
*) mod_expire also issues Cache-Control: max-age headers.
[Rob Hartill]
*) API: Added kill_only_once option for free_proc_chain so that it won't
aggressively try to kill off specific children. For fastcgi.
[Stanley Gambarin <gambarin@OpenMarket.com>]
*) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
*) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
When used together, these cause mod_dir to emit HEIGHT and WIDTH
attributes in the FancyIndexing IMG tags. [Ken Coar]
*) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
*) PORT: Added Windows NT support
[Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
Changes with Apache 1.2.6
*) mod_include when using XBitHack Full would send ETags in addition to
sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
[Dean Gaudet] PR#1133
*) SECURITY: When a client connects to a particular port/addr, and
gives a Host: header ensure that the virtual host requested can
actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
*) Support virtual hosts with wildcard port and/or multiple ports
properly. [Ed Korthof <ed@organic.com>]
*) Fixed some case-sensitivity issues according to RFC2068.
[Dean Gaudet]
*) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
and mod_include.c. [Dean Gaudet]
*) Variable 'cwd' was being used pointlessly before being set.
[Ken Coar] PR#1738
*) SIGURG doesn't exist on all platforms.
[Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
*) When an error occurs during a POST, or other operation with a
request body, the body has to be read from the net before allowing
a keepalive session to continue. [Roy Fielding] PR#1399
*) When an error occurs in fcntl() locking suggest the user look up
the docs for LockFile. [Dean Gaudet]
*) table_set() and table_unset() did not deal correctly with
multiple occurrences of the same key. [Stephen Scheck
<sscheck@infonex.net>, Ben Laurie] PR#1604
*) send_fd_length() did not calculate total_bytes_sent properly in error
cases. [Ben Reser <breser@regnow.com>] PR#1366
*) r->connection->user was allocated in the wrong pool causing corruption
in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
*) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
Also removed the auto-generated link to www.apache.org that was the
source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
*) Multiple "close" tokens may have been set in the "Connection"
header, not an error, but a waste.
[Ronald.Tschalaer@psi.ch] PR#1683
*) "basic" and "digest" auth tokens should be tested case-insensitive.
[Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
*) It appears the "257th byte" bug (see
htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
at the 256th byte as well. Fixed. [Dean Gaudet]
*) mod_rewrite would not handle %3f properly in some situations.
[Ralf Engelschall]
*) Apache could generate improperly chunked HTTP/1.1 responses when
the bputc() or rputc() functions were used by modules (such as
mod_include). [Dean Gaudet]
*) #ifdef wrap a few #defines in httpd.h to make life easier on
some ports. [Ralf Engelschall]
*) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
*) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
*) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
Changes with Apache 1.2.5
*) SECURITY: Fix a possible buffer overflow in logresolve. This is
only an issue on systems without a MAXDNAME define or where
the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
*) Fix an improper length in an ap_snprintf call in proxy_date_canon().
[Marc Slemko]
*) Fix core dump in the ftp proxy when reading incorrectly formatted
directory listings. [Marc Slemko]
*) SECURITY: Fix possible minor buffer overflow in the proxy cache.
[Marc Slemko]
*) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
is used to read various types of files such as htaccess and
htpasswd files. [Marc Slemko]
*) SECURITY: Ensure that the buffer returned by ht_time is always
properly null terminated. [Marc Slemko]
*) SECURITY: General mod_include cleanup, including fixing several
possible buffer overflows and a possible infinite loop. This cleanup
was done against 1.3 code and then backported to 1.2, the result
is a large difference (due to indentation cleanup in 1.3 code).
Users interested in seeing a smaller set of relevant differences
should consider comparing against src/modules/standard/mod_include.c
from the 1.3b3 release. Non-indentation changes to mod_include
between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
*) SECURITY: Numerous changes to mod_imap in a general cleanup
including fixing a possible buffer overflow. This cleanup also
was done with 1.3 code as a basis, see the the previous note
about mod_include. [Dean Gaudet]
*) SECURITY: If a htaccess file can not be read due to bad
permissions, deny access to the directory with a HTTP_FORBIDDEN.
The previous behavior was to ignore the htaccess file if it could not
be read. This change may make some setups with unreadable
htaccess files stop working. PR#817 [Marc Slemko]
*) SECURITY: no2slash() was O(n^2) in the length of the input.
Make it O(n). This inefficiency could be used to mount a denial
of service attack against the Apache server. Thanks to

Changes with Apache 1.2.4
*) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
always making requests with the full-URI instead of just the URI path.
[Marc Slemko, Roy Fielding]
*) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
on this platform. [Marc Slemko]
Changes with Apache 1.2.3
*) The request to a remote proxy was mangled if it was generated as the
result of a ProxyPass directive. URL schemes other than http:// were not
supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
PR#812 [Lars Eilebrecht]
*) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
information for case where proxy module is not available. [Marc Slemko]
*) Force proxy to always respond as HTTP/1.0, which it was failing to
do for errors and cached responses. [Roy Fielding]
*) PORT: Improved support for ConvexOS 11. [Jeff Venters]
Changes with Apache 1.2.2 [not released]
*) Fixed another long-standing bug in sub_req_lookup_file where it would
happily skip past access checks on subdirectories looked up with relative
paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
[Dean Gaudet]
*) Add lockfile name to error message printed out when
USE_FLOCK_SERIALIZED_ACCEPT is defined.
[Marc Slemko]
*) Enhanced the chunking and error handling inside the buffer functions.
[Dean Gaudet, Roy Fielding]
*) When merging the main server's <Directory> and <Location> sections into
a vhost, put the main server's first and the vhost's second. Otherwise
the vhost can't override the main server. [Dean Gaudet] PR#717
*) The <Directory> code would merge and re-merge the same section after
a match was found, possibly causing problems with some modules.
[Dean Gaudet]
*) Fixed an infinite loop in mod_imap for references above the server root.
[Dean Gaudet] PR#748
*) mod_include cleanup showed that handle_else was being used to handle
endif. It didn't cause problems, but it was cleaned up too.
[Howard Fear]
*) Last official synchronization of mod_rewrite with author version (because
mod_rewrite is now directly developed by the author at the Apache Group):
o added diff between mod_rewrite 3.0.6+ and 3.0.9
minus WIN32/NT stuff, but plus copyright removement.
In detail:
- workaround for detecting infinite rewriting loops
- fixed setting of env vars when "-" is used as subst string
- fixed forced response code on redirects (PR#777)
- fixed cases where r->args is ""
- kludge to disable locking on pipes under braindead SunOS
- fix for rewritelog in cases where remote hostname is unknown
- fixed totally damaged request_rec walk-back loop
o remove static from local data and add static to global ones.
o replaced ugly proxy finding stuff by simple
find_linked_module("mod_proxy") call.
o added missing negation char on rewritelog()
o fixed a few comment typos
[Ralf S. Engelschall]
*) Anonymous_LogEmail was logging on each subrequest.
[Dean Gaudet] PR#421, PR#868
*) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
"downgrade-1.0" which causes Apache to pretend it received a 1.0.
Additionally mod_browser now triggers during translate_name to workaround
a deficiency in the header_parse phase.

*) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
under Solaris 2.x (up through 2.5.1). It has been fixed.
[Dean Gaudet] PR#832
*) API: In HTTP/1.1, whether or not a request message contains a body
is independent of the request method and based solely on the presence
of a Content-Length or Transfer-Encoding. Therefore, our default
handlers need to be prepared to read a body even if they don't know
what to do with it; otherwise, the body would be mistaken for the
next request on a persistent connection. discard_request_body()
has been added to take care of that. [Roy Fielding] PR#378
*) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
release version number, such that it always increases along the
same lines as our source code branching. [Roy Fielding]
*) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
Changes with Apache 1.2.1
*) SECURITY: Don't serve file system objects unless they are plain files,
symlinks, or directories. This prevents local users from using pipes
or named sockets to invoke programs for an extremely crude form of
CGI. [Dean Gaudet]
*) SECURITY: HeaderName and ReadmeName were settable in .htaccess and
could contain "../" allowing a local user to "publish" any file on
the system. No slashes are allowed now. [Dean Gaudet]
*) SECURITY: It was possible to violate the symlink Options using mod_dir
(headers, readmes, titles), mod_negotiation (type maps), or
mod_cern_meta (meta files). [Dean Gaudet]
*) SECURITY: Apache will refuse to run as "User root" unless
BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
*) CONFIG: If a symlink pointed to a directory then it would be disallowed
if it contained a .htaccess disallowing symlinks. This is contrary
to the rule that symlink permissions are tested with the symlink
options of the parent directory. [Dean Gaudet] PR#353
*) CONFIG: The LockFile directive can be used to place the serializing
lockfile in any location. It previously defaulted to /usr/tmp/htlock.
[Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
Marc Slemko]
*) Request processing now retains state of whether or not the request
body has been read, so that internal redirects and subrequests will
not try to read it twice (and block). [Roy Fielding]
*) Add a placeholder in modules/Makefile to avoid errors with certain
makes. [Marc Slemko]
*) QUERY_STRING was unescaped in mod_include, it shouldn't be.
[Dean Gaudet] PR#644
*) mod_include was not properly changing the current directory.
[Marc Slemko] PR#742
*) Attempt to work around problems with third party libraries that do not
handle high numbered descriptors (examples include bind, and
solaris libc). On all systems apache attempts to keep all permanent
descriptors above 15 (called the low slack line). Solaris users
can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
which keeps all non-FILE * descriptors above 255. On all systems
this should make supporting large numbers of vhosts with many open
log files more feasible. If this causes trouble please report it,
you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
[Dean Gaudet] various PRs
*) Related to the last entry, network sockets are now opened before
log files are opened. The only known case where this can cause
problems is under Solaris with many virtualhosts and many Listen
directives. But using -DHIGH_SLACK_LINE=256 described above will
work around this problem. [Dean Gaudet]
*) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
SunOS 4.
*) Improved unix error response logging. [Marc Slemko]
*) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
QSA=query_string_append. Also fixed a nasty bug in per-dir context:
when a URL http://... was used in conjunction with a special
redirect flag, e.g. R=permanent, the permanent status was lost.

Changes with Apache 1.2
Changes with Apache 1.2b11
*) Fixed open timestamp fd in proxy_cache.c [Chuck Murcko]
*) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
[Doug MacEachern, Rob Hartill]
*) Proxy needs to use hard_timeout instead of soft_timeout when it is
reading from one buffer and writing to another, at least until it has
a custom timeout handler. [Roy Fielding and Petr Lampa]
*) Fixed problem on IRIX with servers hanging in IdentityCheck,
apparently due to a mismatch between sigaction and setjmp.
[Roy Fielding] PR#502
*) Log correct status code if we timeout before receiving a request (408)
or if we received a request-line that was too long to process (414).
[Ed Korthof and Roy Fielding] PR#601
*) Virtual hosts with the same ServerName, but on different ports, were
not being selected properly. [Ed Korthof]
*) Added code to return the requested IP address from proxy_host2addr()
if gethostbyaddr() fails due to reverse DNS lookup problems. Original
change submitted by Jozsef Hollosi <hollosi@sbcm.com>.
[Chuck Murcko] PR#614
*) If multiple requests on a single connection are used to retrieve
data from different virtual hosts, the virtual host list would be
scanned starting with the most recently used VH instead of the first,
causing most virtual hosts to be ignored.
[Paul Sutton and Martin Mares] PR#610
*) The OS/2 handling of process group was broken by a porting patch for
MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]
*) Inherit virtual server port from main server if none (or "*") is
given for VirtualHost. [Dean Gaudet] PR#576
*) If the lookup for a DirectoryIndex name with content negotiation
has found matching variants, but none are acceptable, return the
negotiation result if there are no more DirectoryIndex names to lookup.
[Petr Lampa and Roy Fielding]
*) If a soft_timeout occurs after keepalive is set, then the main child
loop would try to read another request even though the connection
has been aborted. [Roy Fielding]
*) Configure changes: Allow for whitespace at the start of a
Module declaration. Also, be more understanding about the
CC=/OPTIM= format in Configuration. Finally, fix compiler
flags if using HP-UX's cc compiler. [Jim Jagielski]
*) Subrequests and internal redirects now inherit the_request from the
original request-line. [Roy Fielding]
*) Test for error conditions before creating output header fields, since
we don't want the error message to include those fields. Likewise,
reset the content_language(s) and content_encoding of the response
before generating or redirecting to an error message, since the new
message will have its own Content-* definitions. [Dean Gaudet]
*) Restored the semantics of headers_out (headers sent only with 200..299
and 304 responses) and err_headers_out (headers sent with all responses).
Avoid the overhead of copying tables if err_headers_out is empty
(the usual case). [Roy Fielding]
*) Fixed a couple places where a check for the default Content-Type was
not properly checking both the value configured by the DefaultType
directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
of DEFAULT_TYPE to match the documented default (text/plain).
[Dean Gaudet] PR#506
*) Escape the HTML-sensitive characters in the Request-URI that is
output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
*) Properly initialize the flock structures used by the mutex locking
around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
[Marc Slemko]
*) The method for determining PATH_INFO has been restored to the pre-1.2b
(and NCSA httpd) definition wherein it was the extra path info beyond
the CGI script filename. The environment variable FILEPATH_INFO has
been removed, and instead we supply the original REQUEST_URI to any
script that wants to be Apache-specific and needs the real URI path.
This solves a problem with existing scripts that use extra path info
in the ScriptAlias directive to pass options to the CGI script.
[Roy Fielding]
*) The _default_ change in 1.2b10 will change the behaviour on configs
that use multiple Listen statements for listening on multiple ports.
But that change is necessary to make _default_ consistent with other
forms of <VirtualHost>. It requires such configs to be modified
to use <VirtualHost _default_:*>. The documentation has been
updated. [Dean Gaudet] PR#530
*) If an ErrorDocument CGI script is used to respond to an error
generated by another CGI script which has already read the message
body of the request, the server would block trying to read the
message body again. [Rob Hartill]
*) signal() replacement conflicted with a define on QNX (and potentially
other platforms). Fixed. [Ben Laurie] PR#512
Changes with Apache 1.2b10
*) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
to be configured via -D in Configuration. [Dean Gaudet] PR#449
*) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]

*) In mod_proxy.c, check return values for proxy_host2addr() when reading
config, in case the hostent struct returned is trash.
[Chuck Murcko] PR #491
*) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
Changes with Apache 1.2b9 [never announced]
*) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
changes and in anticipation of 1.2 final release. [Roy Fielding]
*) Fix problem with scripts not receiving a SIGPIPE when client drops
the connection (e.g., when user presses Stop). Apache will now stop
trying to send a message body immediately after an error from write.
[Roy Fielding and Nathan Kurz] PR#335
*) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
than mod_alias, and mod_alias has higher priority than mod_proxy;
rearranged other modules to enhance understanding of their purpose
and relative order (and maybe even reduce some overhead).
[Roy Fielding and Sameer Parekh]
*) Fix graceful restart. Eliminate many signal-related race
conditions in both forms of restart, and in SIGTERM. See
htdocs/manual/stopping.html for details on stopping and
restarting the parent. [Dean Gaudet]
*) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
memory allocator to avoid a behaviour that required extra blocks to
be allocated. [Dean Gaudet]
*) Allow suexec to access files relative to current directory but not
above. (Excluding leading / or any .. directory.) [Ken Coar]
PR#269, 319, 395
*) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
PR#367, 368, 354, 453
*) Fix the above fix: if suexec is enabled, avoid destroying r->url
while obtaining the /~user and save the username in a separate data
area so that it won't be overwritten by the call to getgrgid(), and
fix some misuse of the pool string allocation functions. Also fixes
a general problem with parsing URL query info into args for CGI scripts.
[Roy Fielding] PR#339, 367, 354, 453
*) Fix IRIX warning about bzero undefined. [Marc Slemko]
*) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
*) Corrected spelling of "authoritative". AuthDBAuthoratative became
AuthDBAuthoritative. [Marc Slemko] PR#420
*) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
*) The default handler now logs invalid methods or URIs (i.e. PUT on an
object that can't be PUT, or FOOBAR for some method FOOBAR that
apache doesn't know about at all). Log 404s that occur in mod_include.
[Paul Sutton, John Van Essen]
*) If a soft timeout (or lingerout) occurs while trying to flush a
buffer or write inside buff.c or fread'ing from a CGI's output,
then the timeout would be ignored. [Roy Fielding] PR#373
*) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
parsing of headers. If the terminating empty-line CRLF occurs starting
at the 256th or 257th byte of output, then Navigator will think a normal
image is invalid. We are guessing that this is because their initial
read of a new request uses a 256 byte buffer. We check the bytes written
so far and, if we are about to tickle the bug, we instead insert a
padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
*) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
of an external redirection. [Roy Fielding and Paul Sutton]
*) Configure would create a broken Makefile if the configuration file
contained a commented-out Rule. [Roy Fielding]
*) Promote per_dir_config and subprocess_env from the subrequest to the
main request in mod_negotiation. In particular this fixes a bug
where <Files> sections wouldn't properly apply to negotiated content.
[Dean Gaudet]
*) Fix a potential deadlock in mod_cgi script_err handling.
[Ralf S. Engelschall]
*) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
[Mitchell Blank Jr]
*) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
.htaccess files because the RewriteBase was not replaced correctly.
Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
<Directory> sections missing a trailing /. [Ralf S. Engelschall]
*) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
1.x the settings are those of pre-1.2b8. For 2.x we include
USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
HAVE_SYS_RESOURCE_H (enable the RLimit commands).
[Dean Gaudet] PR#336, PR#340
*) Redirect did not preserve ?query_strings when present in the client's
request. [Dean Gaudet]
*) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
*) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
*) Add UnixWare compile/install instructions. [Chuck Murcko]
*) Add mod_example (illustration of API techniques). [Ken Coar]
*) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
*) Improve handling of directories when filenames have spaces in them.
[Chuck Murcko]
*) For hosts with multiple IP addresses, try all additional addresses if
necessary to get a connect. Fail only if hostent address list is
exhausted. [Chuck Murcko]
*) More signed/unsigned port fixes. [Dean Gaudet]
*) HARD_SERVER_LIMIT can be defined in the Configuration file now.
[Dean Gaudet]
Changes with Apache 1.2b8
*) suexec.c doesn't close the log file, allowing CGIs to continue writing
to it. [Marc Slemko]
*) The addition of <Location> and <File> directives made the
sub_req_lookup_simple() function bogus, so we now handle
the special cases directly. [Dean Gaudet]
*) We now try to log where the server is dumping core when a fatal
signal is received. [Ken Coar]
*) Improved lingering_close by adding a special timeout, removing the
spurious log messages, removing the nonblocking settings (they
are not needed with the better timeout), and adding commentary
about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
*) Send error messages about setsockopt failures to the server error
log instead of stderr. [Roy Fielding]
*) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
*) Stopgap solution for CGI 3-second delay with server-side includes: if
processing a subrequest, allocate memory from r->main->pool instead
of r->pool so that we can avoid waiting for free_proc_chain to cleanup
in the middle of an SSI request. [Dean Gaudet] PR #122
*) Fixed status of response when POST is received for a nonexistent URL
(was sending 405, now 404) and when any method is sent with a
full-URI that doesn't match the server and the server is not acting
as a proxy (was sending 501, now 403). [Roy Fielding]
*) Host port changed to unsigned short. [Ken Coar] PR #276
*) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
*) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
*) Report extra info from errno with many errors that cause httpd to exit.
spawn_child, popenf, and pclosef now have valid errno returns in the
event of an error. Correct problems where errno was stomped on
before being reported. [Dean Gaudet]
*) In the proxy, if the cache filesystem was full, garbage_coll() was
never called, and thus the filesystem would remain full indefinitely.
We now also remove incomplete cache files left if the origin server
didn't send a Content-Length header and either the client has aborted
transfer or bwrite() to client has failed. [Petr Lampa]
*) Fixed the handling of module and script-added header fields.
Improved the interface for sending header fields and reduced
the duplication of code between sending okay responses and errors.
We now always send both headers_out and err_headers_out, and
ensure that the server-reserved fields are not being overridden,
while not overriding those that are not reserved. [Roy Fielding]
*) Moved transparent content negotiation fields to err_headers_out
to reflect above changes. [Petr Lampa]
*) Fixed the determination of whether or not we should make the
connection persistent for all of the cases where some other part
of the server has already indicated that we should not. Also
improved the ordering of the test so that chunked encoding will
be set whenever it is desired instead of only when KeepAlive
is enabled. Added persistent connection capability for most error
responses (those that do not indicate a bad input stream) when
accessed by an HTTP/1.1 client. [Roy Fielding]
*) Added missing timeouts for sending header fields, error responses,
and the last chunk of chunked encoding, each of which could have
resulted in a process being stuck in write forever. Using soft_timeout
requires that the sender check for an aborted connection rather than
continuing after an EINTR. Timeouts that used to be initiated before
send_http_header (and never killed) are now initiated only within or
around the routines that actually do the sending, and not allowed to
propagate above the caller. [Roy Fielding]
*) mod_auth_anon required an @ or a . in the email address, not both.
[Dirk vanGulik]
*) per_dir_defaults weren't set correctly until directory_walk for
name-based vhosts. This fixes an obscure bug with the wrong config
info being used for vhosts that share the same ip as the server.
[Dean Gaudet]
*) Improved generation of modules/Makefile to be more generic for
new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
*) Generate makefile dependency for Configuration based on the actual
name given when running the Configure process. [Dean Gaudet]
*) Fixed problem with vhost error log not being set prior to
initializing virtual hosts. [Dean Gaudet]
*) Fixed infinite loop when a trailing slash is included after a type map
file URL (extra path info). [Petr Lampa]
*) Fixed server status updating of per-connection counters. [Roy Fielding]
*) Add documentation for DNS issues (reliability and security), and try
to explain the virtual host matching process. [Dean Gaudet]
*) Try to continue gracefully by disabling the vhost if a DNS lookup
fails while parsing the configuration file. [Dean Gaudet]
*) Improved calls to setsockopt. [Roy Fielding]
*) Negotiation changes: Don't output empty content-type in variant list;
Output charset in variant list; Return sooner from handle_multi() if
no variants found; Add handling of '*' wildcard in Accept-Charset.
[Petr Lampa and Paul Sutton]
*) Fixed overlaying of request/sub-request notes and headers in
mod_negotiation. [Dean Gaudet]
*) If two variants' charset quality are equal and one is the default
charset (iso-8859-1), then prefer the variant that was specifically
listed in Accept-Charset instead of the default. [Petr Lampa]
*) Memory allocation problem in push_array() -- it would corrupt memory
when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
*) invoke_handler() doesn't handle mime arguments in content-type
[Petr Lampa] PR#160
*) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.

*) Fixed problem with ErrorDocument not working for virtual hosts
due to one of the performance changes in 1.2b7. [Dean Gaudet]
*) Log an error message if we get a request header that is too long,
since it may indicate a buffer overflow attack. [Marc Slemko]

*) Fixed user and server confusion over what should be a virtual host
and what is the main server, resulting in access to something
other than the name defined in the virtualhost directive (but
with the same IP address) failing. [Dean Gaudet]
*) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
AIX; improves the redirection stuff to enable the users to generally
redirect to http, https, gopher and ftp; added TIME variable for
RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
special patterns >STRING, <STRING and =STRING to RewriteCond, which
can be used in conjunction with %{TIME} or other variables to create
time-dependent rewriting rules. [Ralf S. Engelschall]
*) bpushfd() no longer notes cleanups for the file descriptors it is handed.
Module authors may need to adjust their code for proper cleanup to take
place (that is, call note_cleanups_for_fd()). This change fixes problems
with file descriptors being erroneously closed when the proxy module was
in use. [Ben Laurie]
*) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
initgroups() to hose the group information needed for later
comparisons. [Randy Terbush]

caused a SEGV on some systems.
*) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.

[Chuck Murcko]
*) more proxy FTP bug fixes:
- Changed send_dir() to remove user/passwd from displayed URL.
- Changed login error messages to be more descriptive.
- remove setting of SO_DEBUG socket option
- Make ftp_getrc() more lenient about multiline responses,
specifically, 230 responses which don't have continuation 230-
on each line). These seem to be all NT FTP servers, and while
perhaps questionable, they appear to be legal by RFC 959.
- Add missing kill_timeout() after transfer to user completes.
[Chuck Murcko]
*) Fixed problem where a busy server could hang when restarting
after being sent a SIGHUP due to child processes not exiting.
[Marc Slemko]
*) Modify mod_include escaping so a '\' only signifies an escaped
character if the next character is one that needs
escaping. [Ben Laurie]
*) Eliminated possible infinite loop in mod_imap when relative URLs are
used with a 'base' directive that does not have a '/' in it.
[Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
*) Reduced the default timeout from 1200 seconds to 300, and the
one in the sample configfile from 400 to 300. [Marc Slemko]
*) Stop vbprintf from crashing if given a NULL string pointer;
print (null) instead. [Ken Coar]
*) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
[Marc Slemko and Roy Fielding]
*) Fixed problem with mod_cgi-generated internal redirects trying to
read the request message-body twice. [Archie Cobbs and Roy Fielding]
*) Reduced timeout on lingering close, removed possibility of a blocked
read causing the child to hang, and stopped logging of errors if
the socket is not connected (reset by client). [Roy Fielding]
*) Rearranged main child loop to remove duplication of code in
select/accept and keep-alive requests, fixed several bugs regarding
checking scoreboard_image for exit indication and failure to
account for all success conditions and trap all error conditions,
prevented multiple flushes before closing the socket; close the entire
socket buffer instead of just one descriptor, prevent logging of
EPROTO and ECONNABORTED on platforms where supported, and generally
improved readability. [Roy Fielding]
*) Extensive performance improvements. Cleaned up inefficient use of
auto initializers, multiple is_matchexp calls on a static string,
and excessive merging of response_code_strings. [Dean Gaudet]
*) Added double-buffering to mod_include to improve performance on
server-side includes. [Marc Slemko]
*) Several fixes for suexec wrapper. [Randy Terbush]
- Make wrapper work for files on NFS filesystem.
- Fix portability problem of MAXPATHLEN.
- Fix array overrun problem in clean_env().
- Fix allocation of PATH environment variable
*) Removed extraneous blank line is description of mod_status chars.
[Kurt Kohler]
*) Logging of errors from the call_exec routine simply went nowhere,
since the logfile fd has been closed, so now we send them to stderr.
[Harald T. Alvestrand]
*) Fixed core dump when DocumentRoot is a CGI.
[Ben Laurie, reported by geddis@tesserae.com]
*) Fixed potential file descriptor leak in mod_asis; updated it and
http_core to use pfopen/pfclose instead of fopen/fclose.
[Randy Terbush and Roy Fielding]
*) Fixed handling of unsigned ints in ap_snprintf() on some chips such
as the DEC Alpha which is 64-bit but uses 32-bit ints.
[Dean Gaudet and Ken Coar]
*) Return a 302 response code to the client when sending a redirect
due to a missing trailing '/' on a directory instead of a 301; now
it is cacheable. [Markus Gyger]
*) Fix condition where, if a bad directive occurs in .htaccess, and
sub_request() goes first to this directory, then log_reason() will
SIGSEGV because it doesn't have initialized r->per_dir_config.
[PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
*) Fix handling of lang_index in is_variant_better(). This was
causing problems which resulted in the server sending the
wrong language document in some cases. [Petr Lampa]
*) Remove free() from clean_env() in suexec wrapper. This was nuking
the clean environment on some systems.
*) Tweak byteserving code (e.g. serving PDF files) to work around
bugs in Netscape Navigator and Microsoft Internet Explorer.
Emit Content-Length header when sending multipart/byteranges.
[Alexei Kosut]
*) Port to HI-UX/WE2. [Nick Maclaren]
*) Port to HP MPE operating system for HP 3000 machines
[Mark Bixby <markb@cccd.edu>]
*) Fixed bug which caused a segmentation fault if only one argument
given to RLimit* directives. [Ed Korthof]
*) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
*) Improved buffered output to the client by delaying the flush decision
until the BUFF code is actually about to read the next request.
This fixes a problem introduced in 1.2b5 with clients that send
an extra CRLF after a POST request. Also improved chunked output
performance by combining writes using writev() and removing as
many bflush() calls as possible. NOTE: Platforms without writev()
must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
or Configure, unless we have already done so. [Dean Gaudet]
*) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
*) Fixed mod_info output corruption bug introduced by buffer overflow
fixes. [Dean Gaudet]
*) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
for the special case of a 304 response. [Paul Sutton]
*) Improved handling of TRACE method by bypassing normal method handling
and header parsing routines; fixed Allow response to always allow TRACE.
[Dean Gaudet]
*) Fixed compiler warnings in the regex library. [Dean Gaudet]
*) Cleaned-up some of the generated HTML. [Ken Coar]
Changes with Apache 1.2b6
*) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
*) Fix typo introduced in fix for potential infinite loop around
accept() in child_main(). This change caused the rev to 1.2b6.
1.2b5 was never a public beta.
Changes with Apache 1.2b5
*) Change KeepAlive semantics (On|Off instead of a number), add
MaxKeepAliveRequests directive. [Alexei Kosut]
*) Various NeXT compilation patches, as well as a change in
regex/regcomp.c since that file also used a NEXT define.
[Andreas Koenig]
*) Allow * to terminate the end of a directory match in mod_dir.
Allows /~* to match for both /~joe and /~joe/. [David Bronder]
*) Don't call can_exec() if suexec_enabled. Calling this requires
scripts executed by the suexec wrapper to be world executable, which
defeats one of the advantages of running the wrapper. [Randy Terbush]
*) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
[Jim Jagielski]
*) Migration from sprintf() to snprintf() to avoid buffer
overflows. [Marc Slemko]
*) Provide portable snprintf() implementation (ap_snprintf)
as well as *cvt family. [Jim Jagielski]
*) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
[Jim Jagielski]
*) Remove mod_fastcgi.c from the distribution. This module appears
to be maintained more through the Open Market channels and should
continue to be easily available at http://www.fastcgi.com/
*) Fixed bug in modules/Makefile that wouldn't allow building in more
than one subdirectory (or cleaning, either). [Jeremy Laidman]
*) mod_info assumed that the config files were relative to ServerRoot.
[Ken the Rodent]
*) CGI scripts called as an error document resulting from failed
CGI execution would hang waiting for POST'ed data. [Rob Hartill]
*) Log reason when mod_dir returns access HTTP_FORBIDDEN
[Ken the Rodent]
*) Properly check errno to prevent display of a directory index
when server receives a long enough URL to confuse stat().
[Marc Slemko]
*) Several security enhancements to suexec wrapper. It is _highly_
recommended that previously installed versions of the wrapper
be replaced with this version. [Randy Terbush, Jason Dour]
- ~user execution now properly restricted to ~user's home
directory and below.
- execution restricted to UID/GID > 100
- restrict passed environment to known variables
- call setgid() before initgroups() (portability fix)
- remove use of setenv() (portability fix)
*) Add HTTP/1.0 response forcing. [Ben Laurie]
*) Add access control via environment variables. [Ben Laurie]
*) Add rflush() function. [Alexei Kosut]
*) remove duplicate pcalloc() call in new_connection().
*) Fix incorrect comparison which could allow number of children =
MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
*) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
AIX PS/2, CONVEXOS. [Jim Jagielski]
*) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
It's more portable. [Martin Kraemer]
*) Replace references to make in Makefile.tmpl with $(MAKE).
[Chuck Murcko]
*) Add ProxyBlock directive w/IP address caching. Add IP address
caching to NoCache directive as well. ProxyBlock works with all
handlers; NoCache now also works with FTP for anonymous logins.
Still more code cleanup. [Chuck Murcko]
*) Add "header parse" API hook [Ben Laurie]
*) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
*) suEXEC wrapper was freeing memory that had not been malloc'ed.
*) Correctly allow access and auth directives in <Files> sections in
server config files. [Alexei Kosut]
*) Fix bug with ServerPath that could cause certain files to be not
found by the server. [Alexei Kosut]
*) Fix handling of ErrorDocument so that it doesn't remove a trailing
double-quote from text and so that it properly checks for unsupported
status codes using the new index_of_response interface. [Roy Fielding]
*) Multiple fixes to the lingering_close code in order to avoid being
interrupted by a stray timeout, to avoid lingering on a connection
that has already been aborted or never really existed, to ensure that
we stop lingering as soon as any error condition is received, and to
prevent being stuck indefinitely if the read blocks. Also improves
reporting of error conditions. [Marc Slemko and Roy Fielding]
*) Fixed initialization of parameter structure for sigaction.
[mgyger@itr.ch, Adrian Filipi-Martin]
*) Fixed reinitializing the parameters before each call to accept and
select, and removed potential for infinite loop in accept.
[Roy Fielding, after useful PR from adrian@virginia.edu]
*) Fixed condition where, if a child fails to fork, the scoreboard would
continue to say SERVER_STARTING forever. Eventually, the main process
would refuse to start new children because count_idle_servers() will
count those SERVER_STARTING entries and will always report that there
are enough idle servers. [Phillip Vandry]
*) Fixed bug in bcwrite regarding failure to account for partial writes.
Avoided calling bflush() when the client is pipelining requests.
Removed unnecessary flushes from http_protocol. [Dean Gaudet]
*) Added description of "." mode in server-status [Jim Jagielski]
Changes with Apache 1.2b4
*) Fix possible race condition in accept_mutex_init() that
could leave a small security hole open allowing files to be
overwritten in cases where the server UID has write permissions.
[Marc Slemko]
*) Fix awk compatibilty problem in Configure. [Jim Jagielski]
*) Fix portablity problem in util_script where ARG_MAX may not be
defined for some systems.
*) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
[Randal Schwartz]
*) OS/2 changes to support an MMAP style scoreboard file and UNIX
style magic #! token for better script portability. [Garey Smiley]
*) Fix bug in suexec wrapper introduced in b3 that would cause failed
execution for ~userdir CGI. [Jason Dour]
*) Fix initgroups() business in suexec wrapper. [Jason Dour]
*) Fix month off by one in suexec wrapper logging.
Changes with Apache 1.2b3:
*) Fix error in mod_cgi which could cause resources not to be properly
freed, or worse. [Dean Gaudet]
*) Fix find_string() NULL pointer dereference. [Howard Fear]
*) Add set_flag_slot() at the request of Dirk and others.
[Dirk vanGulik]
*) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
*) Add changes to improve the error message given for invalid
ServerName parameters. [Dirk vanGulik]
*) Add "Authoritative" directive for Auth modules that don't
currently have it. This gives admin control to assign authoritative
control to an authentication scheme and allow "fall through" for
those authentication modules that aren't "Authoritative" thereby
allowing multiple authentication mechanisms to be chained.
[Dirk vanGulik]
*) Remove requirement for ResourceConfig/AccessConfig if not using
the three config file layout. [Randy Terbush]
*) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
*) Changes to suexec wrapper to fix the following problems:
1. symlinked homedirs will kill ~userdirs.
2. initgroups() on Linux 2.0.x clobbers gr->grid.
3. CGI command lines paramters problems
4. pw-pwdir for "docroot check" still the httpd user's pw record.
[Randy Terbush, Jason Dour]
*) Change create_argv() to accept variable arguments. This fixes
a problem where arguments were not getting passed to the CGI via
argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
*) Collapse multiple slashes in path URLs to properly apply
handlers defined by <Location>. [Alexei Kosut]
*) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
*) Improve the accuracy of request duration timings by setting
r->request_time in read_request_line() instead of read_request().
[Dean Gaudet]
*) Reset timeout while reading via get_client_block() in mod_cgi.c
Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
*) Add the ability to pass different Makefile.tmpl files to Configure
using the -make flag. [Rob Hartill]
*) Fix coredump triggered when sending a SIGHUP to the server caused
by an assertion failure, in turn caused by an uninitialised field in a
listen_rec.
[Ben Laurie]
*) Add FILEPATH_INFO variable to CGI environment, which is equal to
PATH_INFO from previous versions of Apache (in certain situations,
Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
[later removed in 1.2b11]
*) Add rwrite() function to API to allow for sending strings of
arbitrary length. [Doug MacEachern]
*) Remove rlim_t typedef for NetBSD. Do older versions need this?
*) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
NeXT. [Jim Jagielski]
*) Removed recent modification to promote the status code on internal
redirects, since the correct fix was to change the default log format
in mod_log_config so that it outputs the original status. [Rob Hartill]
Changes with Apache 1.2b2:
*) Update set_signals() to use sigaction() for setting handlers.
This appears to fix a re-entrant problem in the seg_fault()
bus_error() handlers. [Randy Terbush]
*) Changes to allow mod_status compile for OS/2 [Garey Smiley]
*) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
*) proxy_http.c bugfixes: [Chuck Murcko]
1) fixes possible NULL pointer reference w/NoCache
2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
host would cache nothing if it was in the local domain,
and the local domain was in the NoCache list)
3) Adds Host: header when not available
4) Some code cleanup and clarification
*) mod_include.c bugfixes:
1) Fixed an ommission that caused include variables to not
be parsed in config errmsg directives [Howard Fear]
2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
4) Allow backslash-escaping to all quoted text
[Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
5) Pass variable to command line if not set in XSSI's env
[Howard Fear]
*) Fix infinite loop when processing Content-language lines in
type-map files. [Alexei Kosut]
*) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
*) Fixed problem in set_[user|group] that prevented CGI execution
for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
*) Added PORTING information file. [Jim Jagielski]
*) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
*) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
*) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
USE_FCNTL_SERIALIZED_ACCEPT was intended.
*) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
which caused problems of systems where socket s_addr is >32bits.
*) Added comment to explain (r->chunked = 1) side-effect in
http_protocol.c [Roy Fielding]
*) Replaced use of index() in mod_expires.c with more appropriate
and portable isdigit() test. [Ben Laurie]
*) Updated Configure for ...
OS/2 (DEF_WANTHSREGEX=yes, other code changes)
*-dg-dgux* (bad pattern match)
QNX (DEF_WANTHSREGEX=yes)
*-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
*-ultrix (new)
*-unixware211 (new)
and added some user diagnostic info. [Ben Laurie]
*) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
for better portability. [Jim Jagielski]
*) Updated helpers/GuessOS for ...
SCO 5 (recognize minor releases)
SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
IRIX64 (-sgi-irix64)
ULTRIX (-unknown-ultrix)
SINIX (-whatever-sysv4)
NCR Unix (-ncr-sysv4)
and fixed something in helpers/PrintPath [Ben Laurie]
Changes with Apache 1.2b1
*) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
Changes with Apache 1.1.1
*) Fixed bug where Cookie module would make two entries in the
logfile for each access [Mark Cox]

leak. [Nathan Neulinger]
*) MultiViews now works correctly with AddHandler [Alexei Kosut]
*) Problems with mod_auth_msql fixed [Dirk vanGulik]
*) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
Changes with Apache 1.1.0

*) Bring QNX support up to date. [Ben Laurie]
*) Make virtual hosts default to main server keepalive parameters.
[Alexei Kosut, Ben Laurie]
*) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]

a) yet more mod_proxy bugs [Ben Laurie]
b) CGI works again with inetd [Alexei Kosut]
c) Leading colons were stripped from passwords [osm@interguide.com]
d) Another fix to multi-method Limit problem [jk@tools.de]
Changes with Apache 1.1b4
*) r->bytes_sent variable restored. [Robert Thau]
*) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
*) More possibly unsecure programs removed from the support directory.
*) More mod_auth_msql authentication improvements.
*) VirtualHosts based on Host: headers no longer conflict with the
Listen directive.
*) OS/2 compatibility enhancements. [Gary Smiley]
*) POST now allowed to directory index CGI scripts.
*) Actions now work with files of the default type.
*) Bugs which were fixed:
a) more mod_proxy bugs
b) early termination of inetd requests
c) compile warnings on several systems
d) problems when scripts stop reading output early
Changes with Apache 1.1b3
*) Much of cgi-bin and all of cgi-src has been removed, due to
various security holes found and that we could no longer support
them.
*) The "Set-Cookie" header is now special-cased to not merge multiple
instances, since certain popular browsers can not handle multiple
Set-Cookie instructions in a single header. [Paul Sutton]
*) rprintf() added to buffer code, occurrences of sprintf removed.
[Ben Laurie]
*) CONNECT method for proxy module, which means tunneling SSL should work.
(No crypto needed) Also a NoCache config directive.
*) Several API additions: pstrndup(), table_unset() and get_token()
functions now available to modules.
*) mod_imap fixups, in particular Location: headers are now complete
URL's.
*) New "info" module which reports on installed module set through a
special URL, a la mod_status.
*) "ServerPath" directive added - allows for graceful transition
for Host:-header-based virtual hosts.
*) Anonymous authentication module improvements.
*) MSQL authentication module improvements.
*) Status module design improved - output now table-based. [Ben Laurie]
*) htdigest utility included for use with digest authentication
module.
*) mod_negotiation: Accept values with wildcards to be treated with
less priority than those without wildcards at the same quality
value. [Alexei Kosut]
*) Bugs which were fixed:
a) numerous mod_proxy bugs
b) CGI early-termination bug [Ben Laurie]
c) Keepalives not working with virtual hosts
d) RefererIgnore problems
e) closing fd's twice in mod_include (causing core dumps on
Linux and elsewhere).
Changes with Apache 1.1b2
*) Bugfixes:
a) core dumps in mod_digest
b) truncated hostnames/ip address in the logs
c) relative URL's in mod_imap map files
Changes with Apache 1.1b1
*) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
Changes with Apache 1.0.3
*) Internal redirects which occur in mod_dir.c now preserve the
query portion of a request (the bit after the question mark).
[Adam Sussman]
*) Escape active characters '<', '>' and '&' in html output in
directory listings, error messages and redirection links.
[David Robinson]
*) Apache will now work with LynxOS 2.3 and later [Steven Watt]
*) Fix for POSIX compliance in waiting for processes in alloc.c.
[Nick Williams]
*) setsockopt no longer takes a const declared argument [Martijn Koster]
*) Reset timeout timer after each successful fwrite() to the network.
This patch adds a reset_timeout() procedure that is called by
send_fd() to reset the timeout ever time data is written to the net.
[Nathan Schrenk]
*) timeout() signal handler now checks for SIGPIPE and reports
lost connections in a more user friendly way. [Rob Hartill]
*) Location of the "scoreboard" file which used to live in /tmp is
now configurable (for OSes that can't use mmap) via ScoreBoardFile
which works similar to PidFile (in httpd.conf) [Rob Hartill]
*) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
*) the pstrcat call in mod_cookies.c didn't have an ending NULL,
which caused a SEGV with cookies enabled
*) Output warning when MinSpareServers is set to <= 0 and change it to 1
[Rob Hartill]
*) Log the UNIX textual error returned by some system calls, in
particular errors from accept() [David Robinson]
*) Add strerror function to util.c for SunOS4 [Randy Terbush]
Changes with Apache 1.0.2
*) patch to get Apache compiled on UnixWare 2.x, recommended as
a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
*) Fix get_basic_auth_pw() to set the auth_type of the request.
[David Robinson]
*) past changes to http_config.c to only use the
setrlimit function on systems defining RLIMIT_NOFILE
broke the feature on SUNOS4. Now defines HAVE_RESOURCE
for SUNOS and prototypes the needed functions.
*) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
[David Robinson]
*) Fix use of pointer to scratch memory. [Cliff Skolnick]
*) Merge multiple headers from CGI scripts instead of taking last
one. [David Robinson]
*) Add support for SCO 5. [Ben Laurie]
Changes with Apache 1.0.1
*) Silence mod_log_referer and mod_log_agent if not configured
[Randy Terbush]
*) Recursive includes can occur if the client supplies PATH_INFO data
and the server provider uses relative links; as file.html
relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
*) The replacement for initgroups() did not call {set,end}grent(). This
had two implications: if anything else used getgrent(), then
initgroups() would fail, and it was consuming a file descriptor.
[Ben Laurie]
*) On heavily loaded servers it was possible for the scoreboard to get
out of sync with reality, as a result of a race condition.
The observed symptoms are far more Apaches running than should
be, and heavy system loads, generally followed by catastrophic
system failure. [Ben Laurie]
*) Fix typo in license. [David Robinson]
Changes with Apache 1.0.0 23 Nov 1995
*) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
Changes with Apache 0.8.16 05 Nov 1995
*) New man page for 'httpd' added to support directory [David Robinson]
*) .htgroup files can have more than one line giving members for a
given group (each must have the group name in front), for NCSA
back-compatibility [Robert Thau]
*) Mutual exclusion around accept() is on by default for SVR4 systems
generally, since they generally can't handle multiple processes in
accept() on the same socket. This should cure flaky behavior on
a lot of those systems. [David Robinson]
*) AddType, AddEncoding, and AddLanguage directives take multiple
extensions on a single command line [David Robinson]
*) UserDir can be disabled for a given virtual host by saying
"UserDir disabled" in the <VirtualHost> section --- it was a bug
that this didn't work. [David Robinson]
*) Compiles on QNX [Ben Laurie]
*) Corrected parsing of ctime time format [David Robinson]
*) httpd does a perror() before exiting if it can't log its pid
to the PidFile, to make diagnosing the error a bit easier.
[David Robinson]
*) <!--#include file="..."--> can no longer include files in the
parent directory, for NCSA back-compatibility. [David Robinson]
*) '~' is *not* escaped in URIs generated for directory listings
[Roy Fielding]
*) Eliminated compiler warning in the imagemap module [Randy Terbush]
*) Fixed bug involving handling URIs with escaped %-characters
in redirects [David Robinson]
Changes with Apache 0.8.15 14 Oct 1995

*) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
*) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
*) Reject paths containing %-escaped '%' or null characters [David Robinson]
*) Correctly handles internal redirects to files with names containing '%'
[David Robinson]
*) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
*) Use geteuid() rather than getuid() to see if we have root privilege,
so that server correctly resets privilege if run setuid root. [Andrew
Wilson]
*) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
[Randy Terbush]
*) Fix relative URLs in imagemap files [Randy Terbush]
*) Somewhat better fix for the old "Alias /foo/ /bar/" business
[David Robinson]
*) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
entries all name the same one. [David Robinson]
*) Fix directory listings with filenames containing unusual characters
[David Robinson]
*) Better URI-escaping for generated URIs in directories with filenames
containing unusual characters [Ben Laurie]
*) Fixed potential FILE* leak in http_main.c [Ben Laurie]
*) Unblock alarms on error return from spawn_child() [David Robinson]
*) Sample Config files have extra note for SCO users [Ben Laurie]
*) Configuration has note for HP-UX users [Rob Hartill]
*) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
*) Nuked bogus #define in httpd.h [David Robinson]
*) Better test for whether a system has setrlimit() [David Robinson]
*) Calls update_child_status() after reopen_scoreboard() [David Robinson]
*) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
[Ben Laurie]
Changes with Apache 0.8.14 19 Sep 1995
*) Compiles on SCO ODT 3.0 [Ben Laurie]
*) AddDescription works (better) [Ben Laurie]
*) Leaves an intelligible error diagnostic when it can't set group
privileges on standalone startup [Andrew Wilson]
*) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
that machine, which claims to be BSD but does not support RLIMIT.
[Randy Terbush]
*) gcc -Wall no longer complains about an unused variable when util.c
is compiled with -DMINIMAL_DNS [Andrew Wilson]
*) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
Changes with Apache 0.8.13 07 Sep 1995
*) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
*) Have built-in imagemap code recognize & honor Point directive [James
Cloos]
*) Generate cleaner directory listings in directories with a mix of
long and short filenames [Rob Hartill]
*) Properly initialize dynamically loaded modules [Royston Shufflebotham]
*) Properly default ServerName for virtual servers [Robert Thau]
*) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
Paul Richards and a cast of thousands...]
*) On self-identified BSD systems (we don't try to guess any more),
allocate a few extra file descriptors per virtual host with setrlimit,
if we can, to avoid running out. [Randy Terbush]
*) Write 22-character lock file name into buffer with enough space
on startup [Konstantin Olchanski]
*) Use archaic setpgrp() interface on NeXT, which requires it [Brian
Pinkerton]
*) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
*) Suppress -Wall warning by initializing variable in negotiation code
[Tobias Weingartner]
Changes with Apache 0.8.12 31 Aug 1995
*) Doesn't pause three seconds after including a CGI script which is
too slow to die off (this is done by not even trying to kill off
subprocesses, including the SIGTERM/pause/SIGKILL routine, until
after the entire document has been processed). [Robert Thau]
*) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
*) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
*) Allows .htaccess files to override <Directory> sections naming the
same directory [David Robinson]
*) Removed an efficiency hack in sub_req_lookup_uri which was
causing certain extremely marginal cases (e.g., ScriptAlias of a
*particular* index.html file) to fail. [David Robinson]
*) Doesn't log an error when the requested URI requires
authentication, but no auth header line was supplied by the
client; this is a normal condition (the client doesn't no auth is
needed here yet). [Robert Thau]
*) Behaves more sanely when the name server loses its mind [Sean Welch]
*) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
*) RFC931 code no longer passes out name of prior clients on current
requests if the current request came from a server that doesn't
do RFC931. [David Robinson]
*) Configuration script accepts "Module" lines with trailing whitespace.
[Robert Thau]
*) Cleaned up compiler warning from mod_access.c [Robert Thau]
*) Cleaned up comments in mod_cgi.c [Robert Thau]
Changes with Apache 0.8.11 24 Aug 1995
*) Wildcard <Directory> specifications work. [Robert Thau]
*) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
*) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
the file being requested itself, in addition to the directories leading
up to it. [Robert Thau]
*) Logs access failures due to symlink checks or invalid client address
in the error log [Roy Fielding, Robert Thau]
*) Symlink checks deal correctly with systems where lstat of
"/path/to/some/link/" follows the link. [Thau, Fielding]
*) Doesn't reset DirectoryIndex to 'index.html' when
other directory options are set in a .htaccess file. [Robert Thau]
*) Clarified init code and nuked bogus warning in mod_access.c
[Florent Guillaume]
*) Corrected several directives in sample srm.conf
--- includes corrections to directory indexing icon-related directives
(using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
icons for encodings right, and turning on AddEncoding by default).
[Roy Fielding]
*) Corrected descriptions of args to AddIcon and AddAlt in command table
[James Cloos]
*) INSTALL & README mention "contributed modules" directory [Brian
Behlendorf]
*) Fixed English in the license language... "for for" --> "for".
[Roy Fielding]
*) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
mod_alias.c, merging it almost completely with handling of Alias, and
adding a 'notes' field to the request_rec which allows the CGI module
to discover whether the Alias module has put this request through
ScriptAlias (which it needs to know for back-compatibility, as the old
NCSA code did not check Options ExecCGI in ScriptAlias directories).
[Robert Thau]
Changes with Apache 0.8.10 18 Aug 1995
*) AllowOverride applies to the named directory, and not just
subdirectories. [David Robinson]
*) Do locking for accept() exclusion (on systems that need it)
using a special file created for the purpose in /usr/tmp, and
not the error log; using the error log causes real problems
if it's NFS-mounted; this is known to be the cause of a whole
lot of "server hang" problems with Solaris. [David Robinson;
thanks to Merten Schumann for help diagnosing the problem].
Changes with Apache 0.8.9 12 Aug 1995
*) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
*) Nested includes see environment variables of the including document,
for NCSA bug-compatibility (some sites have standard footer includes
which try to print out the last-modified date). [Eric Hagberg/Robert
Thau]
*) <!--exec cgi="/some/uri/here"--> always treats the item named by the
URI as a CGI script, even if it would have been treated as something
else if requested directly, for NCSA back-compatibility. (Note that
this means that people who know the name of the script can see the
code just by asking for it). [Robert Thau]
*) New version of dbmmanage script included in support directory as
dbmmanage.new.
*) Check if scoreboard file couldn't be opened, and say so, rather
then going insane [David Robinson]
*) POST to CGI works on A/UX [Jim Jagielski]
*) AddIcon and AddAlt commands work properly [Rob Hartill]
*) NCSA server push works properly --- the Arena bug compatibility
workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
if you still want the workaround). [Rob Hartill]
*) If client didn't submit any Accept-encodings, ignore encodings in
content negotiation. (NB this will all have to be reworked anyway
for the new HTTP draft). [Florent Guillaume]
*) Don't dump core when trying to log timed-out requests [Jim Jagielski]
*) Really honor CacheNegotiatedDocs [Florent Guillaume]
*) Give Redirect priority over Alias, for NCSA bug compatibility
[David Robinson]
*) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
paralleling earlier bug fix for CGI [David Robinson]
*) If DBM auth is improperly configured, report a server error and don't
dump core.
*) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
it seems to work well enough without it (even in a 10 hits/sec
workout), and the overhead for the locking under A/UX is
alarmingly high (though it is very low on other systems).
[Eric Hagberg, Jim Jagielski]
*) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
*) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
Behlendorf/Eric Hagberg]
*) More improvements to default Configuration for A/UX [Jim Jagielski]
*) Compiles clean on NEXT [Rob Hartill]
*) Compiles clean on SGI [Robert Thau]
Changes with Apache 0.8.8 08 Aug 1995
*) SunOS library prototypes now never included unless explicitly
requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
people using GNU libc on SunOS are screwed by prototypes for the
standard library.
(Those who wish to compile clean with gcc -Wall on a standard
SunOS setup need the prototypes, and may obtain them using
-DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
with nonstandard libraries are presumably competent to make their
own arrangements).
*) Strips trailing '/' characters off both args to the Alias command,
to make 'Alias /foo/ /bar/' work.
Changes with Apache 0.8.7 03 Aug 1995
*) Don't hang when restarting with a child from 'TransferLog "|..."' running
[reported by David Robinson]
*) Compiles clean on OSF/1 [David Robinson]
*) Added some of the more recent significant changes (AddLanguage stuff,
experimental LogFormat support) to CHANGES file in distribution root
directory
Changes with Apache 0.8.6 02 Aug 1995
*) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
(If you actually wanted a conditional GET which bypassed the cache, you
couldn't get it). [Reported by Roy Fielding]
*) Properly terminate headers on '304 Not Modified' replies to conditional
GETs --- no browser we can find cares much, but the CERN proxy chokes.
[Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
*) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
*) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
and older versions don't set the __SUNPRO_C preprocessor variable). On
all other systems, these are never used anyway. [Reported by Mark Cox].
*) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
Changes with Apache 0.8.5 01 Aug 1995
*) Added last-minute configurable log experiment, as optional module
*) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
properly. (One-line fix to http_protocol.c).
*) Work around bogus behavior when reloading from Netscape.
It's Netscape's bug --- for some reason they expect a request with
If-modified-since: to not function as a conditional GET if it also
comes with Pragma: no-cache, which is way out of line with the HTTP
spec (according to Roy Fielding, the redactor).
*) Added parameter to set maximum number of server processes.
*) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
Jim Jagielski]
*) IdentityCheck bugfix [Chuck Murcko].
*) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
*) More sample config file corrections; add extension to AddType for
*.asis, move AddType generic description to its proper place, and
fix miscellaneous typos. [ Alexei Kosut ]
*) Deleted the *other* reference to the regents from the Berkeley
legal disclaimer (everyplace).
*) Nuked Shambhala name from src/README; had already cleaned it out
of everywhere else.
Changes with Apache 0.8.4
*) Changes to server-pool management parms --- renamed current
StartServers to MinSpareServers, created separate StartServers
parameter which means what it says, and renamed MaxServers to
MaxSpareServers (though the old name still works, for NCSA 1.4
back-compatibility). The old names were generally regarded as
too confusing. Also altered "docs" in sample config files.
*) More improvements to default config files ---
sample directives (commented out) for XBitHack, BindAddress,
CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
defaults, AddTypes for send-as-is and imagemap magic types, and
improvements to samples for DirectoryIndex [Alexei Kosut]
*) Yet more improvements to default config files --- changes to
Alexei's sample AddLanguage directives, and sample LanguagePriority
[ Florent Guillaume ]
*) Set config file locations properly if not set in httpd.conf
[ David Robinson ]
*) Don't escape URIs in internal redirects multiple times; don't
do that when translating PATH_INFO to PATH_TRANSLATED either.
[ David Robinson ]
*) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
Changes with Apache 0.8.3
*) Edited distribution README to *briefly* summarize installation
procedures, and give a pointer to the INSTALL file in the src/
directory.
*) Upgraded imagemap script in cgi-bin to 1.8 version from more
recent NCSA distributions.
*) Bug fix to previous bug fix --- if .htaccess file and <Directory>
exist for the same directory, use both and don't segfault. [Reported
by David Robinson]
*) Proper makefile dependencies [David Robinson]
*) Note (re)starts in error log --- reported by Rob Hartill.
*) Only call no2slash() after get_path_info() has been done, to
preserve multiple slashes in the PATH_INFO [NCSA compatibility,
reported by Andrew Wilson, though this one is probably a real bug]
*) Fixed mod_imap.c --- relative paths with base_uri referer don't
dump core when Referer is not supplied. [Randy Terbush]
*) Lightly edited sample config files to refer people to our documentation
instead of NCSA's, and to list Rob McCool as *original* author (also
deleted his old, and no doubt non-functional email address). Would be
nice to have examples of new features...
Changes with Apache 0.8.2 19 Jul 1995
*) Added AddLanuage code [Florent Guillaume]
*) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
*) All sorts of problems when MultiViews finds a directory. It would
be nice if mod_dir.c was robust enough to handle that, but for now,
just punt. [reported by Brian Behlendorf]
*) Wait for all children on restart, to make sure that the old socket
is gone and we can reopen it. [reported by Randy Terbush]
*) Imagemap module is enabled in default Configuration
*) RefererLog and UserAgentLog modules properly default the logfile
[Randy Terbush]
*) Mark Cox's mod_cookies added to the distribution as an optional
module (commented out in the default Configuration, and noted as
an experiment, along with mod_dld). [Mark Cox]
*) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
*) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
*) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
*) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
license]
Changes with Apache 0.8.1
*) New imagemap module [Randy Terbush]
*) Replacement referer log module with NCSA-compatible RefererIgnore
[Matthew Gray again]
*) Don't mung directory listings with very long filenames.
[Florent Guillaume]
Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
*) New config script. See INSTALL for info. [Robert Thau]
*) Scoreboard mechanism for regulating the number of extant server
processes. MaxServers and StartServers defaults are the same as
for NCSA, but the meanings are slightly different. (Actually,
I should probably lower the MaxServers default to 10).
Before asking for a new connection, each server process checks
the number of other servers which are also waiting for a
connection. If there are more than MaxServers, it quietly dies
off. Conversely, every second, the root, or caretaker, process
looks to see how many servers are waiting for a new connection;
if there are fewer than StartServers, it starts a new one. This
does not depend on the number of server processes already extant.
The accounting is arranged through a "scoreboard" file, named
/tmp/htstatus.*, on which each process has an independent file
descriptor (they need to seek without interference).
The end effect is that MaxServers is the maximum number of
servers on an *inactive* server machine, but more will be forked
off to handle unusually heavy loads (or unusually slow clients);
these will die off when they are no longer needed --- without
reverting to the overhead of full forking operation. There is a
hard maximum of 150 server processes compiled in, largely to
avoid forking out of control and dragging the machine down.
(This is arguably too high).
In my server endurance tests, this mechanism did not appear to
impose any significant overhead, even after I forced it to put the
scoreboard file on a normal filesystem (which might have more
overhead than tmpfs). [Robert Thau]
*) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
[Cliff Skolnick]
*) Read .htaccess files even in directory with <Directory> section.
(Former incompatibility noted on mailing list, now fixed). [Robert
Thau]
*) "HEAD /" gives the client a "Bad Request" error message, rather
than trying to send no body *and* no headers. [Cliff Skolnick].
*) Don't produce double error reports for some very obscure cases
mainly involving auth configuration (the "all modules decline to
handle" case which is a sure sign of a server bug in most cases,
but also happens when authentication is badly misconfigured).
[Robert Thau]
*) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
it's *for*, and this sort of thing really shouldn't be cluttering
up the Makefile). [Robert Thau]
*) Incidental code cleanups in http_main.c --- stop dragging
sa_client around; just declare it where used. [Robert Thau]
*) Another acc-related fix. (It doesn't like const char
in some places...). [Mark Cox]
Changes with Shambhala 0.6.1 13 Jul 1995
*) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
Also, fixed auth typo in http_protocol.c unmasked by this fix.
*) Compiles clean with acc on SunOS [Paul Sutton]
*) Reordered modules in modules.c so that Redirect takes priority
over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
believe it or not, he has an actual site with a ScriptAlias and
a Redirect declared for the *exact same directory*. Even *my*
compatibility fetish wouldn't motivate me to fix this if the fix
required any effort, but it doesn't, so what the hey.
*) Fixed to properly default several server_rec fields for virtual
servers from the corresponding fields in the main server_rec.
[Cliff Skolnick --- 'port' was a particular irritant].
*) No longer kills off nph- child processes before they are
finished sending output. [Matthew Gray]
Changes with Shambhala 0.6.0 10 Jul 1995
*) Two styles of timeout --- hard and soft. soft_timeout()s just put
the connection to the client in an "aborted" state, but otherwise
allow whatever handlers are running to clean up. hard_timeout()s
abort the request in progress completely; anything not tied to some
resource pool cleanup will leak. They're still around because I
haven't yet come up with a more elegant way of handling
timeouts when talking to something that isn't the client. The
default_handler and the dir_handler now use soft timeouts, largely
so I can test the feature. [Robert Thau]
*) TransferLog "| my_postprocessor ..." seems to be there. Note that
the case of log handlers dying prematurely is probably handled VERY
gracelessly at this point, and if the logger stops reading input,
the server will hang. (It is known to correctly restart the
logging process on server restart; this is (should be!) going through
the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
script). [Robert Thau]
*) asis files supported (new module). [Robert Thau]
*) IdentityCheck code is compiled in, but has not been tested. (I
don't know anyone who runs identd). [Robert Thau]
*) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
came in with the request, for NCSA bug-compatibility. [Robert Thau]
*) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
*) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
as timeouts are not in scope. [Robert Thau]
*) quoted-string args in config files now handled correctly (doesn't drop
the last character). [Robert Thau; reported by Randy Terbush]
*) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
*) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
default default type); the former default default behavior when all
type-checkers defaulted had been a core dump. [Paul Sutton]
*) Copy filenames out of the struct dirent when indexing
directories. (On Linux, readdir() returns a pointer to the same
memory area every time). Fix is in mod_dir.c. [Paul Sutton]
Changes with Shambhala 0.5.3 [not released]
*) Default response handler notes "file not found" in the error log,
if the file was not found. [Cliff Skolnick].
*) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
code no longer sets up bogus PATH_INFO which fakes out the directory
handler). [Cliff Skolnick]
Changes with Shambhala 0.5.2 06 Jul 1995
*) Changes to http_main.c --- root server no longer plays silly
games with SIGCHLD, and so now detects and replaces dying
children. Child processes just die on SIGTERM, without taking
the whole process group with them. Potential problem --- if any
child process refuses to die, we hang in restart.
MaxRequestsPerChild may still not work, but it certainly works
better than it did before this! [Robert Thau]
*) mod_dir.c bug fixes: ReadmeName and HeaderName
work (or work better, at least); over-long description lines
properly terminated. [Mark Cox]
*) http_request.c now calls unescape_url() more places where it
should [Paul Sutton].
*) More directory handling bugs (reported by Cox)
Parent Directory link is now set correctly. [Robert Thau]
Changes with Shambhala 0.5.1 04 Jul 1995
*) Generalized cleanup interface in alloc.c --- any function can be
registered with alloc.c as a cleanup for a resource pool;
tracking of files and file descriptors has been reimplemented in
terms of this interface, so I can give it some sort of a test.
[Robert Thau]
*) More changes in alloc.c --- new cleanup_for_exec() function,
which tracks down and closes all file descriptors which have been
registered with the alloc.c machinery before the server exec()s a
child process for CGI or <!--#exec-->. CGI children now get
started with exactly three file descriptors open. Hopefully,
this cures the problem Rob H. was having with overly persistent
CGI connections. [Robert Thau]
*) Mutual exclusion around the accept() in child_main() --- this is
required on at least SGI, Solaris and Linux, and is #ifdef'ed in
by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
This uses fcntl(F_SETLK,...) on the error log descriptor because
flock() on that descriptor won't work on systems which have BSD
flock() semantics, including (I think) Linux 1.3 and Solaris.
This does work on SunOS (when the server is idle, only one
process in the pool is waiting on accept()); it *ought* to work
on the other systems. [Robert Thau]
*) FreeBSD and BSDI portability tweaks [Chuck Murcko]
*) sizeof(*sa_client) bugfix from [Rob Hartill]
*) pstrdup(..., NULL) returns NULL, [Randy Terbush]
*) block_alarms() to avoid leaking the DBM* in dbm auth (this should
be unnecessary if I go to the revised timeout-handling scheme).
[Robert Thau]
*) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
string) even if none came in with the request. [Robert Thau]
*) CHANGES file added to distribution ;-).
Changes with Shambhala 0.4.5
*) mod_dld --- early dynamic loading support [rst]
*) Add wildcard content handlers for XBITHACK; default_hander now
invoked with that mechanism (as a handler hanging off mod_core) [rst]
*) XBITHACK supported as a wildcard content-handler, and
configurable at run-time (not just at compile time, as in the
"patchy server" releases) [rst]
Changes with Shambhala 0.4.4 30 Jun 1995
*) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
*) Handle Addtype x/y .z [rst, reported by Cox]
Changes with Shambhala 0.4.3
*) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
synonymous [rst, terbush]
Changes with Shambhala 0.4.1 28 Jun 1995
*) First-cut virtual host implementation; some refit in the config
reading code, and log management, was necessary to support this [rst]
*) Sub-pool machinery, originally added to avoid excessive storage
allocation on listings of large directories (which turned out to
be the problem that the 0.3 storage accounting was added to
find). Subrequests and mod_dir changed to use subpools. [rst]
*) More memory debugging --- free list consistency checks. [rst]
*) Added err_headers to request_rec, with support elsewhere [rst]
*) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
Changes with Shambhala 0.3 19 Jun 1995
*) Switch ONE_PROCESS to a runtime command-line option (-X)
*) Don't compile in mod_ai_backcompat by default
*) Switch name of server from Apache to Shambhala in Makefile
*) Add some accounting routines to track memory usage in the pools,
for debugging
Changes with Shambhala 0.2
*) Set DOCUMENT_ROOT CGI variable
*) Add single-process debugging, as a compile-time option (ONE_PROCESS)
*) Add critical section protection to handling of cleanup structures
in alloc.c [rst]
*) Significant code reorg within the server core to group related
functions together [rst]
*) Correctly handle clients that hang up before sending any request
[rst]
*) Replace dying child processes. [rst]
Changes with Shambhala 0.1 12 Jun 1995
Major rewrite of the pre-existing "patchy server" codebase, by
Robert Thau (rst). Significant portions of the server code, such
as configuration-file handling and HTTP authentication support,
were ripped out and rewritten from scratch. Code that was not
completely rewritten was significantly altered.
Major changes with this release include:
*) Introduction of the module API; in request handling, the central
machinery just dispatches to various modules, which actually do
most of the work. Configuration handling is similar --- modules
declare their own commands, and the central machinery just
dispatches to them.
API features from shambhala/0.1 were substantially unchanged in
Apache 1.0 and 1.1. (1.0 API features not yet present in this
release, such as wildcard handlers and subpools, were added in
subsequent Shambhala releases, and were also generally rst's
work).
*) This release included the following modules:
mod_access (access control --- allow and deny directives),
mod_alias (Alias and Redirect commands),
mod_auth (straight HTTP authentication, based on flat-files)
mod_auth_dbm (same, with dbm files)
mod_cgi (CGI scripts and, in this release, ScriptAlias)
mod_common_log (CLF access logs; later renamed mod_log_common)
mod_dir (directory indexing)
mod_include (server-side includes)
mod_mime (AddType directives)
mod_negotiation (content negotiation)
mod_userdir (support for users' public_html directories)
It also included a mod_ai_backcompat, which was a private hack
for back-compatibility with rst's own AI-lab servers.
All of these modules were substantially complete, and functional
or nearly so (a few, which implemented features not in use at
Thau's site, required patches of a few lines).
*) sub-request machinery, to allow modules to determine how other
modules would assign MIME types to a given file, or optionally
serve its content (this is heavily used by mod_dir, mod_include
and mod_negotiation).
*) Resource pool system for keeping track of memory allocated and
files opened in service of a particular request. Much of the
code in the modules (when they weren't rewrites) was adjusted to
replace a pervasive convention of using fixed-size buffers on
the stack with an equally pervasive convention of using memory
allocated with palloc().
*) Reorganization of data structures associated with a given
request to eliminate use of global variables and the troublesome
unmunge_name function (used in NCSA and early Apache releases to
attempt to determine the URI which mapped to a given filename
--- a difficult proposition, given that it is easy to produce
setups in which multiple URIs map to the same file).
*) Source files renamed and rearranged
*) Very simple pre-forking behavior --- parent process forked off a
fixed number of children, and then just waited for SIGHUP.
*) Other more minor changes too numerous to list.
This release included modified versions of a lot of code from the
Apache 0.6.4 public release, plus an early pre-forking patch
codeveloped by Robert Thau and Rob Hartill.
Changes with Apache 0.7.3 20 Jun 1995
*) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
were incorporated by Rob Hartill on the main branch while Robert Thau
worked on the Shambhala rewrite above. Most were merged into the
Shambala architecture after Apache 0.8.0.
Changes with Apache 0.6.4 13 May 1995
*) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
and others.
Changes with Apache 0.5.1 10 Apr 1995
Changes with Apache 0.4 02 Apr 1995
*) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
and Rob Hartill.
Changes with Apache 0.3 24 Mar 1995
*) Patches by Robert Thau, David Robinson, Rob Hartill, and
Carlos Varela.
Changes with Apache 0.2 18 Mar 1995
*) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
