CURRENT RELEASE NOTES:
|
|
|
|
* Forward binary compatibility is expected of Apache 2.4.x releases, such
|
|
that no MMN major number changes will occur after 2.4.1. Such changes can
|
|
only be made in the trunk.
|
|
|
|
* All commits to branches/2.4.x must be reflected in SVN trunk,
|
|
as well, if they apply. Logical progression is commit to trunk
|
|
then merge into branches/2.4.x, as applicable.
|
|
|
|

2.4.x patch: svn merge ^/httpd/httpd/branches/2.4.x-mpm_fdqueue .
|

(http://home.apache.org/~ylavic/patches/httpd-2.4.x-mpm_fdqueue.patch)
|
|
+1: ylavic, minfrin, jim
|
|
ylavic: The branch merge helps resolve move conflicts since event and
|
|
worker fdqueue.[ch] differ(ed) between 2.4.x and trunk. The patch
|
|
is provided only to help review.
|
|
ylavic: re MMN, the API is private, so no bump (supposedly).
|
|
minfrin: Keeping mpm_fdqueue.h private makes it hard for people to fork event
|
|
and worker and make their own mpms. Can we make this public?
|
|
ylavic: not easier/harder than now I suppose (worker/event fqueues are private).
|
|
maybe make them public in trunk only, so that we have more time to
|
|
discuss the API (if needed).
|
|
minfrin: happy with that, we can backport the final API.
|
|
|
|
*) mpm_event: Do lingering close in worker(s).

2.4.x: trunk patches work, final view:
|
|
http://home.apache.org/~elukey/httpd-2.4.x-core-last_modified_tz_logging.patch
|
|
The problem has been discussed in dev@ extensively but we did not reach a common
|
|
agreement about how to proceed in the long term. While we wait, I would really like
|
|
to introduce useful logs for the users (the starting point of this change was a users@
|
|
email thread). If this is not the right way to go I will move the patch to other
|
|
sections of STATUS (stalled or being worked).
|
|
The code has been tested with a simple PHP script returning different Last-Modified
|
|
headers (GMT now, GMT now Europe/Paris, GMT tomorrow, GMT yesterday, PST now).
|
|
+1: elukey
|
|
|
|
*) http: Don't remove the Content-Length of zero from a HEAD response if
|
|
it comes from an origin server, module or script. Allow the previous
|
|
behaviour (for legacy/buggy modules only, not origin) by also backporting
|
|
the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
|
|
comes for free with the same commit).

2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
|
|
+1: ylavic, jim
|
|
ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
|
|
ints added at the end of core_server_config, the proposed merge
|
|
does a minor bump only.
|
|
minfrin: Two new directives need to be documented.
|
|
|
|
* mod_proxy_http: Don't establish or reuse a backend connection before pre-
|
|
fetching the request body, so to minimize the delay between it is supposed
|
|
to be alive and the first bytes sent: this is a best effort to prevent the
|
|
backend from closing because of idle or keepalive timeout in the meantime.
|
|
Also, handle a new "proxy-flushall" environment variable which allows to
|
|
flush any forwarded body data immediately. PR 56541+37920.
|
|
trunk patch: http://svn.apache.org/r1656259
|
|
http://svn.apache.org/r1656359 (CHANGES entry)
|
|
2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
|
|
+1: ylavic
|
|
-0: jim: This seems to be a hit to normal performance, to handle an
|
|
error and/or non-normal condition. The pre-fetch is
|
|
expensive, and is always done, even before we know that
|
|
the backend is available to rec' it. I understand the
|
|
error described, but is the fix actually worth it (plus
|
|
it seems to allow for a DDoS vector).
|
|
ylavic: It seems to me that the problem is real since we reuse the
|
|
connection before prefetching 16K (either controlled by the
|
|
client, or by an input filter), we currently always prefetch
|
|
these bytes already. Regarding performance I don't see any
|
|
difference (more cycles) compared with the current code.
|
|
However I think I failed to rebuild the header_brigade when
|
|
the proxy loop is retried (ping), so I need to rework this.
|
|
Do you think we'd better remove the prefetch, or maybe just
|
|
make it nonblocking (by default)?
|
|
jim: Non-blocking seems the best way to handle...

|
http://svn.apache.org/r1773870
|
|
http://svn.apache.org/r1773882
|
|
wrowe notes that the current code is too inefficient, owing to the fact
|
|
that the ovector is a required allocation and is no longer allocated on
|
|
the stack, by design. The correct fix is an apr userdata allocation on
|
|
the appropriate pool, which would be thread-safe, but the actual API of
|
|
ap_regexec[_len]() offers us no pool. We cannot associate that pool with
|
|
the ap_regex_t, because a single regex may be used by many threads in
|
|
parallel and is not thread-safe beyond initialization.
|
|
So the only fix allowing us to use PCRE 10 in httpd 2.4 would be to write
|
|
this as a thread safe storage buffer for the majority of cases (<10 $args)
|
|
and we don't have a portable tls mechanism to do so.
|
|
jorton: Adding ap_pregexec/_len which pass a pool would also work
|
|
for internal users of this api; not sure if performance
|
|
impact is significant from using malloc here.
|
|
|
|
|
|
PATCHES/ISSUES THAT ARE STALLED
|
|
|
|
* core: Add ap_errorlog_provider to make ErrorLog logging modular. This
|
|
backport keeps syslog logging as part of httpd core and only adds
|
|
API to allow other modules to be used for error logging.

|
|
(sorry, haven't finished reviewing completely)
|
|
jim: What is the status of this??
|
|
|
|
* mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
|
|
and ProxyMatch section to distinguish between normal workers and workers
|
|
with regex substitutions in the name. Implement handling of such workers
|
|
in ap_proxy_get_worker(). Fixes the bug when regex workers were not

matched and used for request. PR 43513.

* Makefile.win: Added copying of .vbs / .wsf CGIs to Windows install target.
|
|
Moved fixing of shebang to separate target so that it is
|
|
no longer executed by default and all CGIs remain inactive.

This commit is essentially deciding that an httpd install on
|
|
Windows now has printenv/testcgi written in 2 more languages.
|
|
To the extent that the usefulness is that it shows how to make scripts
|
|
of these types executable by httpd, I believe that the documentation
|
|
is the proper place to solve that. To the extent that the usefullness
|
|
is to show how to implement a CGI in these particular languages, I believe
|
|
that the httpd distribution and documentation in general is not the
|
|
place for that. Historically these types of scripts have caused problems
|
|
for downstream vendorsas well as newbies (and sometimes the intersection
|
|
of those two groups) who don't understand that these are information leaks
|
|
once they are enabled, and the subtlety of the way they are disabled ("Apache
|
|
messed up the first line; let me fix that") contributes to that.
|
|
fuankg notes: I've just added a big warning to all CGI scripts which should now
|
|
make absolutely clear that these CGIs are for testing purpose only - so those
|
|
who enable those scripts with inserting the right shebang should be 100% aware
|
|
of any risks (this should cover your last point).
|
|
jim: trawick, does the above address your concerns?
|
|
trawick: to some extent (somebody reading the script gets an idea)
|
|
Why isn't the configuration requirement documented instead
|
|
of described indirectly in a sample?
|
|
Why are these new samples added to the install without three
|
|
votes? (I didn't veto it; put your name next to the two
|
|
existing ones and I'll be satisfied that enough people
|
|
considered this addition as an appropriate solution for a
|
|
real httpd usability problem.)
|
|
wrowe: I'd agree with trawick, and suggest that these scripts can begin
|
|
their life somewhere in the manual/ tree. This really seems like
|
|
the place where /usr/share/httpd/examples/ would be useful, but
|
|
there isn't an ordinary directory for that. Since we want none
|
|
of the scripts to function 'out of the box', what about a new
|
|
cgi-examples/ dir alongside cgi-bin/? Otherwise manual/cgi/examples
|
|
might work?

|
jchampion: Looks like the headers require GCC extensions to compile, so
|
|
mod_journald can't be configured in maintainer mode (-std=c89).
|
|
Can anyone else reproduce, or is it just my distro?
|
|
ylavic: missing r1812339 for maintainer-mode/c89/-Werror compliance,
|
|
needed if the above configure.in proposal gets backported.
|
|
Note that r1812339 could be backported in any case, even if
|
|
the above configure.in proposal does not get accepted.

sf comments: The IdleShutdown logic seems broken. Consider a single
|
|
active connection that is stalled for 10 seconds. That
|
|
connection will be broken after GracefulShutdownTimeout.
|
|
A better logic would be to check if there is any open
|
|
connection that is not in keep-alive state.
