      The input data (received in one read from TCP layer):

      GET /log4j/ HTTP/1.0
      Via: 1.0 MDRPRXY01, 1.0 NS2
      Connection: Keep-Alive
      User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 4.0)
      Accept: application/, application/msword, application/,
image/gif, image/x-xbitmap, image/jpeg,
      image/pjpeg, */*
      Accept-Language: en-us,tscii;q=0.5
      Accept-Encoding: gzip, deflate

      The confusion was because apr_sendfile() returned APR_SUCCESS
      but zero bytes sent.  Presumably the FreeBSD kernel sendfile()
      did the same thing (not 100% sure).

      Also happened on 20010605...


      GET /builds/jakarta-turbine/release/2.1/ HTTP/1.1
      Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg,

      Accept-Encoding: gzip, deflate
      User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)
      Connection: Keep-Alive

      Again, it would seem that FreeBSD sendfile() returned rc 0 with
      no bytes sent.  (Other eyes welcome, of course... make sure you
      look at 2_0_16 sources.)

    * core dump from 20010521 and 20010529 running 2_0_16 - the "3030" problem

      #0  0x80987e8 in apr_cvt (arg=1.3980432860952889e-76,

      #1  0x30303030 in ?? ()
      Cannot access memory at address 0x30303030. 

      In both coredumps the request is /server-status?auto.

      It is unclear whether the apr_*printf function was passed bad
      data or it screwed up on its own.  0x30 is '0'.  There is a
      string of 200-300 '0' characters in the dump, apparently
      overlaying enough of the stack to cause serious problems :)


    WARNING: ALWAYS check srclib/apr/STATUS and srclib/apr-util/STATUS

    * File handle caching in mod_file_cache is broken in the multi
      threaded MPMs. The original intent of caching file handles 
      was that these handles would ONLY be used in an apr_sendfile()
      call.  With recent optimizations added to core_output_filter
      to pipeline output byte streams, we actually read bytes from
      these cached file handles into buffers. The problem is that
      while it is okay for multiple threads to share a file handle
      for use on a sendfile call (because the filepointer is not used, 
      in sendfile) it is NOT okay for threads to share a file handle
      for reads or writes (because the filepointer is used in reads
      and writes).  This may also be broken on a few quirky platforms
      whose sendfile() actually uses the file pointer.  Jeff was looking
      into that.

      Potential Solutions:
      1. We either need to ensure that a cached file handle is only
         used on a sendfile call (Bill prefers this solution. I think.).
      2. Cliff Woolley has some ideas about a custom bucket type
         that would recognise when an apr_file_t is cached (thus shared
         across threads) and do the right thing to ensure that the
         filepointer does not get trashed.  The idea here is that the
         "cacheable" file bucket would never allow its file handle to be
         read by any method OTHER than sendfile.  Attempts to do otherwise
         would result in the file being re-opened for sync io into the
         request pool, and the new file handle would get put into a regular
         file bucket which would then be read.  This method thus incorporates
         the spirit of solution #1 while having a fall-back protection
         scheme.  Note that mod_file_cache can still attempt to
         be discriminatory and DECLINE requests that it believes will
         result in an apr_bucket_read() call; this solution just allows
         it to not worry TOO much about missing some cases.  Note that
         no locking is involved, and in the worst case (ie, when the cached
         file bucket is read) we are no worse off performance-wise than
         if we'd just DECLINED in the first place.  Patch forthcoming.
      3. You can share a file handle across threads in Windows if you
         open the file for OVERLAPPED io. A file opened for overlapped
         io does not have a file pointer; each thread must manage
         tracking its location in the file explicity. This is a cool
         feature IMHO.  APR would need to be expanded to handle 
         reading and writing to files opened for overlapped io 
         (specifically to manage a per-thread file pointer and handle
         async io events internal to APR). This doesn't fix the problem
         under *ix though. 

    * There is a bug in how we sort some hooks, at least the pre-config
      hook.  The first time we call the hooks, they are in the correct 
      order, but the second time, we don't sort them correctly.  Currently,
      the modules/http/config.m4 file has been renamed to 
      modules/http/config2.m4 to work around this problem, it should moved
      back when this is fixed.    rbb

    * Root all file systems with <Directory /> for WIN32/OS2/NW permissions 
        Status: patch brought forward from 1.3.14
                WIN32 and OS2 need review [William Rowe, Brian Harvard]

    * Win32: Get Apache working on Windows 95/98. The following work
	(at least) needs to be done:
	- winnt MPM: Fix 95/98 code paths in the winnt MPM. There is some NT
	specific code that is still not in NT only code paths
	- IOL binds to APR sendfile, implemented with TransmitFile, which 
        is not available on 95/98.
        - Document warning that OSR2 is required (for Crypt functions, in
        rand.c, at least.)

    * Win32: Test access logging with multiple threads. Will the 
	native file I/O calls serialize automagically like the 
	CRT calls or do we need to add region locking each time 
	we access the logs?

    * Win32: Complete the revamp the service environment and relocation
        into the WinNT MPM.  Changes ServerRoot service registry 
        parameter into ConfigArgs for multiple service startup parameters.
        Problems to fix in the revamp: -k shutdown/restart are broken, 
        signals are not being acknowledged.  Close window and shutdown 
        also seem out of sorts.
        OtherBill is working on this and will finish over the weekend.

    * We need a thread-safe resolver, at least on Unix.
        Status: The best known candidate would be something from
	BIND v9.
        Status: Greg asks, "why? doesn't gethostbyname_r() handle this?"

    * The AddInputFilter and AddOutputFilter directives do not allow the
      administrator to remove or reorder filters.  Once a filter is added
      in a container, it is present in any subcontainers.  It can only be
      added to the filter chain after any filters specified in enclosing

    * remove the --disable-shared from the subdir config of APR(UTIL)
      before the final release. (in fact, it might even be nice to
      allow for Apache config/build against an already-installed
      Note: we need to do a "make install" for APR(UTIL) so the shared
            libraries can be installed properly. We could also use that
            point to install include files (rather than have Apache
	    know everything that needs to be installed from the
	    sub-packages). The original impetus for doing the
	    disable-shared was because the shared lib wasn't getting
	    installed and a "make clean" in aprutil would make Apache
	    fail to load.

    * users who want to install third-party modules into the Apache
      source tree (for static linking) need to have autoconf and
      libtool installed. This is because the module needs to have its
      config.m4 incorporated into ./configure, which means "buildconf"
      must be run.
      Note: This is in part because we have removed the "extra" directory.
            In the Apache-2.0 repository, this directory had a config.m4
            file that allowed people to add external modules by
            specifying --with-module on the configure line.

    * ap_vrprintf() needs to handle more than 4K
        Status: Greg volunteers

    * mod_dir should normally redirect ALL directory requests which do
      not include a trailing slash on the URI. However, if a "notes"
      flag is set (say, via BrowserMatch), this behavior will be
      disabled for non-GET requests.
        Status: Greg volunteers

        MsgId: <3A9C0097.9C83F07C@Golux.Com>

    * Usability: Sanitize the MPM config directives.  MaxClients in 
      the threaded MPM is totally misleading now as it has little to
      do with limiting the number of clients (it limits the number
      of child processes). Bill proposed nomenclature change to
      something like "StartWorkers, MaxWorkers, etc." that could 
      apply to most all the MPMs (with some notable exceptions).
      Bill would be happy with changing MaxClients to MaxServers
      to make it agree with the operation of the StartServers

    * A design problem with the scoreboard can cause the threaded 
      MPM to get in a state where it will no longer serve requests.
      When MaxRequestsPerChild is hit, a threaded process will begin
      allowing it's idle worker threads to exit. The child process
      may have one (or a few) threads serving really long responses
      over slow client connections, which will prevent the child
      process from exiting. The problem is that the
      perform_idle_server_maintenance code will NOT start a new
      process to replace the dying child process until the dying child 
      has exited because the new child needs to use the old childs
      space in the scoreboard. The scoreboard and
      perform_idle_server_maintenance need to be redesigned.
      Status: Several proposals discussed on new-httpd (April 16, 2001)


    * Port of mod_ssl to Apache 2.0:

      The current porting state is summarized in modules/ssl/README.  The next
      step is to figure out how the old three configuration contexts (global,
      per-server, per-directory) can be ported to Apache 2.0 (especially the
      global context which has to survive server restarts RSE still does not
      know how to port). Then the remaining source files (which depend on the
      configuration contexts) which are still tagged with "-" in
      modules/ssl/README can be ported. 
      One more thing to figure out is how and when mod_ssl can provide the
      interactive pass phrase dialog (in Apache 1.3 it used the first init
      round [where tty was still not detached] and skipped the second init
      round [where it was already detached]). Apache 2.0 requires (or already
      has?) an official hook where such tty-dialogs can be performed.

      RSE is on holiday until June 11th, 2001. After this he starts
      working on mod_ssl again and tries to make mod_ssl running inside
      Apache 2.0 by end of June. If anyone wants to help making mod_ssl
      running in the meantime, feel free to make your hands dirty inside
      modules/ssl/. Do whatever you think is appropriate to get it
      running. I've no objections of any kind, except: just do not
      remove any old functionality. Keep everything, even if it needs
      #if 0...endif wrapped to not make trouble for you.

      optimization working again. Bill would like to see this
      working for the threaded MPM, then prefork.

    * mod_tls is very specific to OpenSSL. Make the API calls
      more generic to support other encryption libraries.

    * Performance & Debug: Eliminate most (and perhaps all) of the 
      malloc/calloc/frees in the bucket brigade code.  Need some 
      light weight memory management functions that allow freeing 
      memory (putting it back into a memory pool) when it is no 
      longer needed. Enabling simple debugging features like guard
      bands, double free detection, etc. would be cool but certainly
      not a hard requirement.

    * Eliminate unnecessary creation of pipes in mod_cgid

    * the autoconf setup should be fixed to default to using the 
      "Apache" layout from config.layout, and each variable settable
      in a layout should be overridable on the command line.  Plus,
      what we do right now just doesn't seem to fully fit into how autoconf
      works, eg. AC_PREFIX_DEFAULT issues.
        Message-ID: <>

    * All of our MPMs should use APR for threads/processes.  This 
      will allow us to error out if a threaded MPM is chosen on a
      platform that doesn't support threads.

    * Combine log_child and piped_log_spawn. Clean up http_log.c.
      Common logging API.

    * Document mod_file_cache.

    * OS/2: Make mod_status work for spmt_os2 MPM.

    * Win32: Win9x console window still won't play nice with the
        close window, logoff and shutdown scenarios.
        Status: OtherBill will move the patch forward from 1.3.15, once we 
        get our other Win9x issues solved.

    * Win32: Add a simple hold console open patch (wait for close or
        the ESC key, with a nice message) if the server died a bad 
        death (non-zero exit code) in console mode.
        Status: OtherBill is bringing forward same ugly hack from 1.3.13

    * Platforms that do not support fork (primarily Win32 and AS/400)
      Architect start-up code that avoids initializing all the modules 
      in the parent process on platforms that do not support fork.

    * Win32: Migrate the MPM over to use APR thread/process calls. This
      would eliminate some code in the Win32 branch that essentially
      duplicates what is in APR.

    * There are still a number of places in the code where we are
      losing error status (i.e. throwing away the error returned by a
      system call and replacing it with a generic error code)

    * Mass vhosting version of suEXEC.

    * All DBMs suffer from confusion in support/dbmmanage (perl script) since 
        the dbmmanage employs the first-matched dbm format.  This is not
        necessarily the library that Apache was built with.  Aught to
        rewrite dbmmanage upon installation to bin/ with the proper library 
        for predictable mod_auth_db/dbm administration.

    * use apu_dbm in mod_auth_dbm
        Status: Greg +1 (low-priority volunteer)

    * Integrate mod_dav.
        Some additional items remaining:
	- case_preserved_filename stuff
	    (use the new canonical name stuff?)
	- find a new home for ap_text(_header)
	- is it possible to remove the DAV: namespace stuff from util_xml?

    * ap_core_translate() and its use by mod_mmap_static and mod_file_cache
      are a bit wonky.  The function should probably be exposed as a utility 
      function (such as ap_translate_url2fs() or ap_validate_fs_url() or 
      something).  Another approach would be a new hook phase after
      "translate" which would allow the module to munge what the
      translation has decided to do.
        Status: Greg +1 (volunteers), Ryan +1

    * Explore use of a post-config hook for the code in http_main.c which
      calls ap_fixup_virutal_hosts(), ap_fini_vhost_config(), and
      ap_sort_hooks()  [to reduce the logic in main()]

    * read the config tree just once, and process N times (as necessary)

    * (possibly) use UUIDs in mod_unique_id and/or mod_usertrack

    * (possibly) port the bug fix for PR 6942 (segv when LoadModule is put
      into a VirtualHost container) to 2.0.

    * shift stuff to mod_core.h

    * APR-ize resolver stuff in mod_unique_id (Jeff volunteers)

    * callers of ap_run_create_request() should check the return value
      for failure (Doug volunteers)

    * PR#6347: mod_mime
      MIME types for MNG and JNG files need adding to mime.types and
      the mime.types and magic files
	Status: Waiting for IANA types to be defined

Other bugs that need fixing:

    * MaxRequestsPerChild measures connections, not requests.
        Until someone has a better way, we'll probably just rename it
    * Regex containers don't work in an intutive way
        Status: No one has come up with an efficient way to fix this
        behavior. Dean has suggested getting rid of regex containers

    * SIGSEGV on Linux (glibc 2.1.2) isn't caught properly by a
      sigwaiting thread. We need to work around this, perhaps unless
      there is hope soon for a fixed glibc.

    * orig_ct in the byterange/multipart handling may not be
      needed. Apache 1.3 just never stashed "multipart" into
      r->content_type. We should probably follow suit since the
      byterange stuff doesn't want the rest of the code to see the
      multipart content-type; the other code should still think it is
      dealing with the <orig_ct> stuff.
        Status: Greg volunteers to investigate (esp. since he was most 
                likely the one to break it :-)

Other features that need writing:

    * Finish infrastructure in core for async MPMs
        Status: post 2.0

    * TODO in source -- just do an egrep on "TODO" and see what's there

Documentation that needs writing:
    * Mod_status docs are needed.

    * The concept of MPMs, especially if we ship more than one MPM for a
      given platform

    * New directives in the various MPMs and appropriate links from
	obsolete directives in core.html to the MPM documentation.

    * Revise manual/stopping.html and the last part of
	manual/misc/perf-tuning.html to take account of the MPMs.

    * API documentation
        Status: Ben Laurie has written some hooks documentation

    * Changes since 1.3.9 can be more easily seen in the commitlog file
      which includes some of Roy's comments when the changes were
      committed in rough change-sets by purpose.  Note that the commitlog
      does not show the contents of new files until later.

Available Patches:

   * Jon Travis's <> patch to deal with thread-safe
     issues with inet_ntoa.  See message <>
	Status:  This is being set aside until the IPv6 work is finished
		 so that we know exactly what is required.

   * Martin Sojka <>'s patch to add error reporting for failed 
     htpasswd actions due to a full /tmp volume (other programs may have
     similar problems?)
        PR: 6475

   * Mike Abbott's <> patches to improve
       Status: These were written for 1.3, and are awaiting a port to
   * Jim Winstead's <> patch to add CookieDomain and 
     other small mod_usertrack features

   * Dan Rench's <> patch to add allow the errmsg and timefmt 
     of SSI's to be modified in the config file.  Patch is available in 

Open issues:

   * What do we do about mod_proxy?

   * Which MPMs will be included with Apache 2.0?
