Apache 2.0 STATUS: Last modified at [$Date: 2000/08/17 17:49:04 $] Release: 2.0a6 : ??? 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: * Win32: Socket timeout semantics in Win32 APR are slightly different from Unix semantics. This is mostly due to using setsockopt(SO_SNDTIMEO | SO_RCVTIMEO) in the Win32 socket routines. The major problem in the current implementation is that timeouts apply to sending the entire response. Status: Bill S. is working on this * 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() * 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. <19991103003605.A20612@samosa.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. * Go throught the 1.3 Bug DB and research the bugs marked "suspended". People were told these would be considered for inclusion in Apache 2.0, it would be nice to actually do so. * 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: Status: Greg +1 (volunteers), Jeff +1, Ryan +1, Tony -0(?) * mod_info to use the configuration tree PRs that have been suspended forever waiting for someone to put them into 'the next release': * PR#73: mod_log-any reporting of referer in error_log Status: * PR#76: general missing call to "setlocale();" Status: * PR#78: mod_include Additional status for XBitHack directive Status: * PR#161: mod_dir Questionable performace of mod_dir() with negotiation Status: * PR#362: mod_proxy Mod_proxy doesn't allow change of error pages Status: * PR#370: mod_env Modified PATH environemnt variable is not passed, instead system's is used Status: * PR#440: mod_proxy Proxy doesn't deliver documents if not connected Status: * PR#534: mod_proxy proxy converts ~name to %7Ename when name starts with a dot (.)

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 patches to improve performance Status: These were written for 1.3, and are awaiting a port to 2.0 * 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 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.
