Contributors looking for a mission: * Just do an egrep on "TODO" or "XXX" in the source. * Review the bug database at: http://issues.apache.org/bugzilla/ * Review the "PatchAvailable" bugs in the bug database: https://issues.apache.org/bugzilla/buglist.cgi?bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&product=Apache+httpd-2&keywords=PatchAvailable After testing, you can append a comment saying "Reviewed and tested". * Open bugs in the bug database. * See also the STATUS file in the docs/ directory, which lists documentation-specific TODO items. 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. * Current exceptions for RTC for this branch: . mod_proxy_http2 . mod_md . documentation . non-Unix build . non-Unix, single-platform code . routine APLOGNO() backports . .gdbinit .

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... *) CMake: Use full path to gen_test_char.exe in CUSTOM_COMMAND. trunk patch: http://svn.apache.org/r1902366 2.4.x patch: svn merge -c r1902366 ^/httpd/httpd/trunk . +1: ivan PATCHES/ISSUES THAT ARE STALLED *) core: avoid duplicate headers when using ap_send_error_response. From trunk's testing the code seems running fine without any side effects, so adding this change in here to have more reviews. trunk patch: http://svn.apache.org/r1832092 2.4.x patch: svn merge -c 1832092 ^/httpd/httpd/trunk . +1: elukey +0.5: icing: as I read this, the change preserves the special status of headers in ->err_headers_out, since swapping the tables makes former error headers normal ones. But it is hard to see of this was ever intentional or not. Lack of regressions in testing may meaning someone out there relies on the former, unverified behaviour. OTOH, it fixes and error you saw and added test for. So, I am cautiously for the change. elukey: PR 62025 seems another use case that gets fixed using this patch (still need to get feedback from the reporter but on my local env it solves the problem). elukey: If anybody has time to review this change it would be great, to know if it needs to be reverted, reworked, etc.. I would like to avoid a patch that is clearly wrong for some reviewer sitting here for months/years without any action item :) ylavic: will look at it ASAP.. * core: Add ap_errorlog_provider to make ErrorLog logging modular.

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? *) mod_journald: Add new module mod_journald to log error logs into journald. trunk patch: http://svn.apache.org/r1610339 http://svn.apache.org/r1621806 http://svn.apache.org/r1812339 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-mod_journald.patch http://svn.apache.org/r1812339 +1: jkaluza, jim jchampion: Looks like the headers require GCC extensions to compile, so mod_journald can't be configured in maintainer mode (-std=c89).
