0N/A Status: patch brought forward from 1.3.14
0N/A WIN32 and OS2 need review [William Rowe, Brian Harvard]
0N/A * Win32: Get Apache working on Windows 95/98. The following work
0N/A (at least) needs to be done:
0N/A - winnt MPM: Fix 95/98 code paths in the winnt MPM. There is some NT
0N/A specific code that is still not in NT only code paths
0N/A - IOL binds to APR sendfile, implemented with TransmitFile, which
0N/A is not available on 95/98.
0N/A - Document warning that OSR2 is required (for Crypt functions, in
0N/A * Win32: Test access logging with multiple threads. Will the
0N/A native file I/O calls serialize automagically like the
0N/A CRT calls or do we need to add region locking each time
0N/A * Win32: Complete the revamp the service environment and relocation
0N/A into the WinNT MPM. Changes ServerRoot service registry
0N/A parameter into ConfigArgs for multiple service startup parameters.
0N/A signals are not being acknowledged. Close window and shutdown
0N/A also seem out of sorts.
0N/A OtherBill is working on this and will finish over the weekend.
0N/A * We need a thread-safe resolver, at least on Unix.
0N/A Status: The best known candidate would be something from
0N/A Status: Greg asks, "why? doesn't gethostbyname_r() handle this?"
0N/A * The AddInputFilter and AddOutputFilter directives do not allow the
0N/A administrator to remove or reorder filters. Once a filter is added
0N/A in a container, it is present in any subcontainers. It can only be
0N/A added to the filter chain after any filters specified in enclosing
0N/A * remove the --disable-shared from the subdir config of APR(UTIL)
0N/A before the final release. (in fact, it might even be nice to
0N/A Note: we need to do a "make install" for APR(UTIL) so the shared
0N/A libraries can be installed properly. We could also use that
0N/A point to install include files (rather than have Apache
0N/A know everything that needs to be installed from the
0N/A sub-packages). The original impetus for doing the
0N/A disable-shared was because the shared lib wasn't getting
0N/A installed and a "make clean" in aprutil would make Apache
0N/A * users who want to install third-party modules into the Apache
0N/A source tree (for static linking) need to have autoconf and
0N/A libtool installed. This is because the module needs to have its
0N/A config.m4 incorporated into ./configure, which means "buildconf"
0N/A Note: This is in part because we have removed the "extra" directory.
0N/A In the Apache-2.0 repository, this directory had a
config.m4 0N/A file that allowed people to add external modules by
0N/A specifying --with-module on the configure line.
0N/A * ap_vrprintf() needs to handle more than 4K
0N/A Status: Greg volunteers
0N/A * mod_dir should normally redirect ALL directory requests which do
0N/A not include a trailing slash on the URI. However, if a "notes"
0N/A flag is set (say, via BrowserMatch), this behavior will be
0N/A disabled for non-GET requests.
0N/A Status: Greg volunteers
0N/A MsgId: <20010227104646.E2297@lyra.org>
0N/A MsgId: <3A9C0097.9C83F07C@Golux.Com>
0N/A * Usability: Sanitize the MPM config directives. MaxClients in
0N/A the threaded MPM is totally misleading now as it has little to
0N/A do with limiting the number of clients (it limits the number
0N/A of child processes). Bill proposed nomenclature change to
0N/A something like "StartWorkers, MaxWorkers, etc." that could
0N/A apply to most all the MPMs (with some notable exceptions).
0N/A Bill would be happy with changing MaxClients to MaxServers
0N/A to make it agree with the operation of the StartServers
0N/A * A design problem with the scoreboard can cause the threaded
0N/A MPM to get in a state where it will no longer serve requests.
0N/A When MaxRequestsPerChild is hit, a threaded process will begin
0N/A allowing it's idle worker threads to exit. The child process
0N/A may have one (or a few) threads serving really long responses
0N/A over slow client connections, which will prevent the child
0N/A process from exiting. The problem is that the
0N/A perform_idle_server_maintenance code will NOT start a new
0N/A process to replace the dying child process until the dying child
0N/A has exited because the new child needs to use the old childs
0N/A space in the scoreboard. The scoreboard and
0N/A perform_idle_server_maintenance need to be redesigned.
0N/A Status: Several proposals discussed on new-httpd (April 16, 2001)
0N/ARELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP:
0N/A * Performance: Get SINGLE_LISTENER_UNSERIALIZED_ACCEPT
0N/A optimization working again. Bill would like to see this
0N/A working for the threaded MPM, then prefork.
0N/A * mod_tls is very specific to OpenSSL. Make the API calls
0N/A more generic to support other encryption libraries.
0N/A * Performance & Debug: Eliminate most (and perhaps all) of the
0N/A light weight memory management functions that allow freeing
0N/A memory (putting it back into a memory pool) when it is no
0N/A longer needed. Enabling simple debugging features like guard
0N/A bands, double free detection, etc. would be cool but certainly
0N/A not a hard requirement.
0N/A * Eliminate unnecessary creation of pipes in mod_cgid
0N/A * the autoconf setup should be fixed to default to using the
0N/A in a layout should be overridable on the command line. Plus,
0N/A what we do right now just doesn't seem to fully fit into how autoconf
0N/A works, eg. AC_PREFIX_DEFAULT issues.
0N/A Message-ID: <Pine.BSF.4.20.0104031557420.20876-100000@alive.znep.com>
0N/A will allow us to error out if a threaded MPM is chosen on a
0N/A platform that doesn't support threads.
0N/A * Document mod_file_cache.
0N/A * OS/2: Make mod_status work for spmt_os2 MPM.
0N/A * Win32: Win9x console window still won't play nice with the
0N/A close window, logoff and shutdown scenarios.
0N/A Status: OtherBill will move the patch forward from 1.3.15, once we
0N/A get our other Win9x issues solved.
0N/A * Win32: Add a simple hold console open patch (wait for close or
0N/A the ESC key, with a nice message) if the server died a bad
0N/A death (non-zero exit code) in console mode.
0N/A Status: OtherBill is bringing forward same ugly hack from 1.3.13
0N/A * Platforms that do not support fork (primarily Win32 and AS/400)
0N/A Architect start-up code that avoids initializing all the modules
0N/A in the parent process on platforms that do not support fork.
0N/A would eliminate some code in the Win32 branch that essentially
0N/A duplicates what is in APR.
0N/A * There are still a number of places in the code where we are
0N/A losing error status (
i.e. throwing away the error returned by a
0N/A system call and replacing it with a generic error code)
0N/A * Win32: Implement reliable piped logs on Windows
0N/A * Mass vhosting version of suEXEC.
0N/A the dbmmanage employs the first-matched dbm format. This is not
0N/A necessarily the library that Apache was built with. Aught to
0N/A rewrite dbmmanage upon installation to bin/ with the proper library
0N/A * use apu_dbm in mod_auth_dbm
0N/A Status: Greg +1 (low-priority volunteer)
0N/A * Integrate mod_dav.
0N/A Some additional items remaining:
0N/A - case_preserved_filename stuff
0N/A (use the new canonical name stuff?)
0N/A - find a new home for ap_text(_header)
0N/A - is it possible to remove the DAV: namespace stuff from util_xml?
0N/A * ap_core_translate() and its use by mod_mmap_static and mod_file_cache
0N/A are a bit wonky. The function should probably be exposed as a utility
0N/A function (such as ap_translate_url2fs() or ap_validate_fs_url() or
0N/A something). Another approach would be a new hook phase after
0N/A "translate" which would allow the module to munge what the
0N/A translation has decided to do.
0N/A Status: Greg +1 (volunteers), Ryan +1
0N/A calls ap_fixup_virutal_hosts(), ap_fini_vhost_config(), and

0N/A * (possibly) use UUIDs in mod_unique_id
