* bootstrap.conf: Remove manywarnings, add warnings
* configure.ac: Replace manywarnings code
The new code works on recent gcc and clang with an overhead of
~100ms instead of ~9s here (without -C).
This is meant for developers only and is activated by either
--enable-gcc-warnings or by touching .manywarnings.
* bootstrap.conf: Remove module 'human'
* include/libwget.h.in: Amend wget_human_readable()
* libwget/bar.c: Use new function wget_human_readable()
* libwget/utils.c: Replace wget_human_readable()
* src/wget.c: Use new function wget_human_readable()
* bootstrap.conf: Add the human module and its dependency unistd
* include/libwget.h.in: Replace method signature for wget_human_readable
* libwget/bar.c (_bar_slot_t): Add a new struct memeber for storing the
human readable string that it printed on the progress bar
(wget_bar_init): Initialise the new human_size struct member
(wget_bar_update): Use the new wget_human_readable() method
(_bar_print_final): Same
(wget_bar_deinit): Free the allocated memory for each slot
* libwget/utils.c (wget_human_readable): Replace the old function with a
call to the human_readable() method from gnulib
Give the progress bar its own thread and let it update the entire
display asynchronously at a specified time interval. The existing
implementation refreshes the progress bar for each network packet
downloaded. Over multiple downloader threads and a high speed network
connection this can lead to far too many redrawings of the screen. Also,
each of the downloader threads will block while trying to acquire the
thread mutex because another thread just retrieved a packet. While I
haven't profiled it, it seems like there would be extremely high lock
contention in the existing implementation. Instead, with a separate
thread, we can update all the progress bar slots simultaneously at
regular intervals.
* bootstrap.conf: Include Gnulib module "ioctl"
* include/libwget.h.in: Define always_inline, flatten and deprecated
compiler attributes for both GCC and Clang
* include/libwget.h.in: Export new functions wget_human_readable,
wget_bar_register and wget_bar_deregister.
* include/libwget.h.in (wget_http_response_t): Add new element
"cur_downloaded" to struct. This element keeps a track of the raw
number of bytes downloaded in the response
(_wget_bar_ctx): Define new struct for storing the progress bar
context.
* libwget/bar.c: Fix display of downloaded ratio. Ensure it does not
exceed 100% by comparing the raw downloaded bytes instead of
uncompressed downloaded bytes.
Add support for printing the filename and downloaded bytes to the
progress bar.
* libwget/http.c (wget_http_response_cb): Store the raw number of
bytes downloaded from the network in the response data
* libwget/utils.c (wget_human_readable): New function to convert an
int value to a human readable string
* src/bar.c: Use the entire screen width instead of just 70 columns
for the progress bar.
Provide methods to register and deregister a progress bar
context
(wget_bar_update_thread): New method for the progress bar thread
to update the output periodically.
* src/bar.h: Same
* src/job.h: Move definition of struct DOWNLOADER from main.c to
here
* src/progress.h: Move definition of _body_callback_context from
main.c to here
* src/utils.c: Add new method to determine the width of the screen
* src/utils.h: Same
* src/wget.c: Use the new progress bar contexts. Update, register
and deregister them
(main): Deinit the progress bar only if it was enabled
* src/Makefile.am: Add new files, progress.h, utils.c, utils.h
* bootstrap.conf: add SKIP_PO=1, so that we don't have to pass
the --skip-po flag every time we run bootstrap.
* README.md, contrib/check-hard, contrib/mingw, docs/mainpage.md,
.travis.sh: amend references to autogen.sh.
* autogen.sh: Removed
* .gitignore: Add build-aux
* po/Makevars: Remove auto-generated file from repo
