Agenda for 1.2b7-dev
====================

Patches ready for testing, voting:

  * reduce default timeout to 300 all around
	Status: Marc posted patch

  * warning on SunOS4, http_log.c:164, pointer from int without cast
       Status: Marc posted patch

  * escaping '{''s in SSI has changed.  Bug?
    Message-ID: <Pine.BSF.3.91.970203113400.925C-100000@localhost.imdb.com>
	Status: Ben posted patch 

  * identitycheck and hostnamelookups not allowed in .htaccess but
    documentation says they are.  Update the documentation or perhaps
    make them work as documented.
	Status: no one seems think we should make them work, so I
		am proposing fixing the docs.  If someone thinks
		the source should be fixed so it works as documented,
		say so.

  * Roy's big fixes to main loop, lingering_close patch
	Status: +1 Marc, Randy, Chuck, Jim

  * update bug report page to not have email form
	Status: +1 Roy, Dean, Marc (but some changes suggested), patch
		reposted with changes.  Needs input from people handling
		current bug reports.
	New status: reposted, still need input from people handling bug
		reports via mail right now.  

  * mod_include is slow.  Marc posted an output buffering patch
    that shouldn't help but does.
	Status: +1 Jim, Dean
		Rob tempted to -1: "its a feature"

  * Satisfy Any can be changed if .htaccess exists
        If you give Satisfy Any in access.conf for a particular directory,
        and have a .htaccess in that directory, Satisfy mode reverts
        to Satisfy All even if the .htaccess has _no_ authentication
        directives.

	Status: Ed posted patch, +1 from Paul Sutton, Dean

  * user and server get confused 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.  
		Status: should be looked at, may not be a nice way to fix 
			since it is likely not technically a bug.

	New status: Dean posted patch, Ben +1-but-hasn't tested, may
		or may not be whole problem, Randy +1.

  * Dean's reposted regex -Wall cleanup
	Status: +1 Marc w/1 additional patch

  * Dean's rfc2068 fixes (several parts)
	Status: Roy +1 (on only one part?)

  * fixing server-generated HTML [Ken]
	Status: Chuck +1
		Marc +1 for the <HTML> additions, but not the DOCTYPE

  * correct irix 5.3 -Wall warnings
	Status: Dean posted patch, Marc, Jim +1

  * server can hang on HUP
	Status: Marc posted patch, -1 Chuck because of sleep(2)... but I 
	don't like the alternatives.

  * infinite loop in mod_imap due to parsing bug
	Status: marc posted another patch, Dean +1

  * http_request.c: directory_walk() misses some <Directory ...> directives
    (PR#131).  I'm not sure the way things are done is really incorrect, 
    but should be looked at.
	Status: was actually already committed; should it have been?

Should be done or at least looked at before 1.2b7:

  * Marc has changed his mind and wants to have a check to be sure
    log directory isn't writable by anyone except the user starting
    the server.  Is it too late?  Do we need a conf file directive to
    override it?

  * multiviews not behaving properly with path info (PR#40)

  * docs for force-response-1.0?

  * status report shows PIDs in empty slots, user supplied some sort 
    of patch
    Message-ID: <Pine.NEB.3.95.970212030312.13867I-100000@localhost.imdb.com>

  * status module available from .htaccess files

  * MSIE and byte ranges.  Sigh.

  * let's fix the Solaris 2.6 and HPUX getwd junk the right way.  
    Either get rid of the (one) call to getwd or use ap_getwd and 
    #define it appropriately in conf.h  (PR#89,153)

  * CGIs don't get PIPE under FreeBSD; under Solaris they get a TERM
    and then a PIPE in close succession.  Hmm.  Marc will look when
    he gets a chance.

  * redo lingering_close to check for old sockets to close out before
    accept() in child.  
	Status: Marc will look into

  * if "options IncludesNOEXEC" set in directory, no CGI will work
    Message-Id: <199702102302.PAA11416@taz.hyperreal.com>
	Status: the way it should work, but not how some (including
	Marc) want it to work.

  * Solaris "accept: Too many levels of remote in path" [marc]

  * possible proxy timeout problem [rasmus]

  * <!--#exec cmd="prog args\ with\ spaces"-->
    doesn't work anymore. It passes THREE arguments
    to prog ("args", "with" and "spaces), instead of
    ONE argument ("args with spaces"). [eb@via.ecp.fr]  
    Either need to use \\ or change escaping to not escape things that
    aren't recognized as escape chars.

  * Questionable performace of  mod_dir() with negotiation
	PR#161
 
  * invoke_handler() doesn't handle mime arguments in content-type
	PR#160

  * Memory hog in handle_multi()
	PR#159

  * Variant list in r->notes is deleted if request is comming through mod_dir()
	PR#158

  * handle_multi() doesn't copy request headers for negotiated request
	PR#157

  * If start twice, overwrites the PID file PR#152

  * some better suexec docs would be really nice, detailing some of the
    security risks and compromises discussed
	Status: I think Randy said something about doing it at one point,
		but no one can write what  I think should be there better
		than me, if I ever have time.  Randy says he thinks 
		Jason is perhaps doing them.


  * redirect of index file causes SEGV [Marc]
	Status: have a way to stop the core dump, but that doesn't make
	it work properly.
	See also: Message-ID: <Pine.BSF.3.91.970210204402.12197B-100000@localhost.imdb.com>

  * 64-bit issues; general cleanup, sizeof(void *) != sizeof(int)

  * Randy says "seems that the processes on a Unixware machine are
    eventually all dying off. Mind you, I have not seen this, but
    that is what is being reported.  Sounds like perhaps the server is not 
    respawning new children after MaxRequestsPerChild has been reached."

  * mod_proxy returns incorrect results when given a 'Location:'
    redirect (PR#137)

  * error compiling on NeXT:
	In file included from http_main.c:108:
	/NextDeveloper/Headers/bsd/netinet/tcp.h:57: duplicate member `th_off'
	/NextDeveloper/Headers/bsd/netinet/tcp.h:58: duplicate member `th_x2'

	Status: unknown, NeXT versions may be hell to figure out


  * Marc says Apache won't compile with HAVE_SNPRINTF defined as things
    are now because not everything includes conf.h.
       Status: Fix it when we have a platform which has snprintf.  Jim
	will look at; perhaps just include conf.h everywhere

  * new header_parse API hook is called too often
       Status: RobH posted patch, had second thoughts.  He
       suggests that mod_browser be optimised by detecting if it has been
       called already and returning early if it has.

  * lingering_close generates the following error message
      shutdown: Transport endpoint is not connected - lingering_close
    using 1.2b6 (only a few a day).  I think this is what 
    happens when a client disconnects during transmission, which
    is a normal condition for web servers.  I suggest not logging
    an error if errno == ENOTCONN.
      Marc says that this may not be "normal", it may be if the client
    sends a RST to terminate the connection (as per recent discussion on
    end2end-interest) and it gets here before we get to that point in
    lingering_close.
       Status: no patch, waiting to see if it it improves debugging.

  * SO_DEBUG in proxy_ftp.c may not be portable, see PR 116, 104
       Status: Chuck says it is a leftover, will fix

  * bugs in mod_negotiation (serious)
       Status: reported by lampa@fee.vutbr.cz on Jan 6 to apache-bugs.
               It is a very good, detailed report with patches.

  * 3 seconds delay in CGI execution on SunOS 4.x, see PR 122
       Status: no patch.
       Info: Pages containing script output show up with a delay of 3
             seconds (there was no such delay in Apache 1.1.1). 
             [rindfuss@medea.wz-berlin.de] tracked the problem down to
             source file alloc.c, function free_proc_chain.. This function
             contains a conditional call to sleep(3), which causes the delay.

       for (p = procs; p; p = p->next) {
          if (p->kill_how == kill_after_timeout) {
            /* Subprocess may be dead already.  Only need the timeout if not. */
            if (kill (p->pid, SIGTERM) != -1)  
              need_timeout = 1;
          } else if (p->kill_how == kill_always) {
            kill (p->pid, SIGKILL);
          }
        }
 
        /* Sleep only if we have to... */
  
        if (need_timeout) sleep (3);

        [RobH: So CGI included as SSI hangs around for longer and needs
               to be SIGTERM'ed.  Why?]

        [Roy: note also that a call to sleep will blow-out any other timeout]



Planning/design items:

    * Should we change the default timeout of 1200?
	Status: discussion ongoing, +1 concept Jim, Randy, Marc


    * should the bug report page be in CVS?  Should it be in the htdocs
      tree or a seperate place?  Should it be distributed with Apache?
      The same holds for everything on the Apache web site.  Marc would
      like to see it all in CVS, but not necessarily distributed
      with Apache.

    * should perhaps start to think about exactly how we want to 
      handle contrib patches/programs in 1.2.  Directory on the web site?  
      Include in distribution?


Contrib stuff / future:

    * Chris Adams <cadams@ro.com> patch to mod_log_config to add %m
      and %c.

    * "Large groups cause authentication errors" on FreeBSD
      [salari@cs.ubc.ca]; problem looks to be MAX_STRING_LEN buffer
      in groups_for_user.  

  * mod_log_config patch for conditional logging
	Status: contrib, not in server

    * Jim has patch for time taken to handle a request in status module

  * Ed has an updated patch for limiting connections per IP

  * mod_include is still slow.

  * Some mirrors are out-of-date, Brian will investigate

  * add some setlocale stuff?
