Release:

    2.0a7   : ???
    2.0a6   : released August 18, 2000
    2.0a5   : released August 4, 2000
    2.0a4   : released June 7, 2000
    2.0a3   : released April 28, 2000
    2.0a2   : released March 31, 2000
    2.0a1   : released March 10, 2000

RELEASE SHOWSTOPPERS:

    * All of the bucket types must be implemented.  The list can be found
      in src/include/ap_buckets.h. May need to implement a bucket type
      to mark the end of a subrequest content stream, and one to tell
      filters to flush any pending content. See http_protocol.c:
      ap_finalize_sub_req_protocol() and ap_rflush()
	rbb says:  Creating a bucket to signal end of sub-request ties
		   the filters to Apache.  This can be handled very cleanly
		   by just inserting a sub-request filter.  That filter would
		   be responsible for stripping off the EOS bucket for the
		   sub-request, and removing all vestiges of the request.

    * Remove Buff and IOL from the code.  To do this, a chunking and 
      translation filter must be written.  This allows us to remove BUFF.
      IOLs can be removed as soon as somebody gets to it.

    * apachectl not being built or installed

    * Win32: Get mod_auth_digest working under win32
      - APR_HAS_RANDOM should be defined on windows and there is a 
      lib/apr/misc/win32/rand.c which is basically a copy of what
      mod_auth_digest used to use.

    * suEXEC doesn't work
        Status: Manoj has posted an patch to fix this.
        Message-ID: <20000825024943.A17578@manojk.users.mindspring.com>

    * Win32: Enable the Windows MPM to honor max_requests_per_child
        Status: Bill will fix this.

    * 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.

    * 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?
	Status: 

    * 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

    * Win32: fix build/run time environment to remove ApacheCore.dll 
        linkage from ab.exe and htdigest.exe.
    
    * 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?"

    * Modify mod_cgi and mod_cgid to deal with directories.  This allows
      a lot of directives to be removed from the core.

RELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP:
    * Combine log_child and piped_log_spawn. Clean up http_log.c.
      Common logging API.

    * Create unified scoreboard API and implementation shared across
      the MPMs 

    * Document mod_file_cache.

    * OS/2: Get loadable modules working again. Requires shared core support
      which doesn't appear to be catered for in the current build system.

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

    * Build scripts do not recognise AIX 4.2.1 pthreads, so the
      pthread MPMs will not build.

    * Win32: Enable the winnt MPM to use the new scoreboard API

    * Win32: Implement ap_shm_ functions in APR.

    * Win32: Win9x console window still won't play nice with the
        close window, logoff and shutdown scenarios.

    * 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.

    * Platforms that do not support fork (primarily Win32 and AS/400)
      Consider introducing HAVE_FORK feature macro. 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.

      Bill says we need a new procattr, APR_CREATE_SUSPENDED (or
      something similar) to direct ap_create_process to create the
      process suspended. We also need a call to wake up the suspended 
      process This may not be able to be implemented everywhere though.

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

    * Win32: Implement reliable piped logs on Windows
          
    * The connection status table is not very efficient. Also, very few stats
      are exported to the connection status table (easy to fix), and mod_status
      is ugly.

    * Mass vhosting version of suEXEC.

    * Replace tables with a proper opaque ADT that has pluggable
      implementations (including something like the existing data type,
      plus hash tables for speed, with options for more later).
	Status: fanf is working on this.

    * configuration option to use *DBM
      Status: Greg +1 (volunteers)

    * add SDBM into src/lib/sdbm/ as a default/fallback DBM implementation.
      SDBM is used by Perl, mod_dav, mod_sssl, others for basic DBM support.
      Status: Greg +1 (volunteers)

    * Integrate mod_dav.
        Message-id: <20000625173247.M29590@lyra.org>
        Status: works. passes initial regression testing. Joe Orton
                reports success with his "cadaver" tool.
        Some additional items remaining:
	- case_preserved_filename stuff
        - fix and re-enable sdbm_lock.c
	- 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 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 mod_mmap_static to munge what the translation has
      decided to do.
        Status: Greg +1 (volunteers), Ryan +1

    * Go through ap_config.h and namespace-protect the symbols (e.g. USE_*).
      Some symbols can/should move to mpm_common.h where possible.

    * 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)

    * add a version number to ap_initialize() as an extra failsafe against
      (APR) library version skew.
      MsgID: <Pine.LNX.4.10.10005231712380.31927-100000@nebula.lyra.org>
      Status: Greg +1 (volunteers), Jeff +1, Ryan +1, Tony -0(?)

    * mod_info to use the configuration tree

Other bugs that need fixing:

    * MaxRequestsPerChild measures connections, not requests.
        Until someone has a better way, we'll probably just rename it
        "MaxConnectionsPerChild".
    
    * 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
        completely.

    * 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.

    * The MM library is built as static and shared library. This should
      be set up to build only the required version.

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
        (apache-2.0/htdocs/hooks.html)

    * Changes since 1.3.9 can be more easily seen in the commitlog file
         dev.apache.org:/home/cvs/CVSROOT/commitlogs/apache-2.0
      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:

   * Mike Abbott's <mja@trudge.engr.sgi.com> patches to improve
     performance
       Status: These were written for 1.3, and are awaiting a port to
       2.0
 
   * Jim Winstead's <jimw@trainedmonkey.com> patch to add CookieDomain and 
     other small mod_usertrack features

   * Dan Rench's <drench@xnet.com> patch to add allow the errmsg and timefmt 
     of SSI's to be modified in the config file.  Patch is available in 
     PR6193

Open issues:

   * What do we do about mod_proxy?

   * Which MPMs will be included with Apache 2.0?

   * Is conf/highperformance.conf-dist obsolete?  It looks obsolete.
