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:
    . http/2 - mod_http2
    . mod_lua
    . documentation
    . non-Unix build
    . non-Unix, single-platform code

RELEASE SHOWSTOPPERS:

  *) mod_proxy_hcheck: Ensure thread-safety when concurrent healthchecks are
     in use (ProxyHCTPsize > 0).  PR 60071.

     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...

   * mod_dav: Allow other modules to become providers and add ACLs
     to the DAV response. Requires a release of apr-util v1.6.
     trunk patch: http://svn.apache.org/r1748322
     2.4.x: trunk works modulo CHANGES/MMN
     +1: minfrin
     rpluem asks: Will this compile with apr-util < v1.6 and keep
     mod_dav working (without the new features of the patch of course)?
     I doubt that we will require apr-util 1.6 for the lifetime of 2.4.x
     (see the discussion around ap_cstr_casecmp[n] an apr 1.6)
     minfrin: Yes, as you can see in the patch everything applies only
     if APR_XML_X2T_PARSED is defined, and the patch was tested with
     both apr-util v1.6 and apr-util v1.5.

     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.


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.

   * 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

     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.

     -.8: trawick
          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?

   * core: block Define and Undefine in vhost and directory context. Because
     it is EXEC_ON_READ, it "breaks out" of these contexts anyway.
