6 Vague plan, assuming more features aren't demanded for the 2.0 release
7 2.0a1 : released March 10, 2000
17 * MPMs should have responsibility for closing sockets and
18 registering the socket cleanup. Stop registering multiple
19 cleanups for each socket. Move socket close code out of
20 http_connection.c and into the MPMs.
23 * Reliable piped logs look broken everywhere. Each MPM includes essentially
24 identical code to ap_register_other_child(), etc. Most of this code can
25 be moved out of the MPMs and into some common file (http_core.c?).
26 Dean says presumably you mean an os-specific file?
28 * Pipes to CGI scripts are not being timed out
29 Status: code has been added to APR to support timing out pipes.
30 This needs to be used in Apache now.
32 * Put back resource limit code
35 Status: Manoj has posted an patch to fix this.
36 <19991103003605.A20612@samosa.mindspring.com>
38 * Win32: Enable the Windows MPM to honor max_requests_per_child
39 Status: Bill will fix this.
41 * Win32: Fix Win9* specific code in the winnt MPM
44 * Win32: Test access logging with multiple threads. Will the
45 native file I/O calls serialize automagically like the
46 CRT calls or do we need to add region locking each time
50 * Win32: Smoke test all ported modules to make sure they work
51 correctly under Windows.
54 * Current 2.0 code is not tested on many Unix platforms. Make 2.0
55 work on most, if not all the systems 1.3 did
56 Status: Autoconf and APR will get us most of the way there.
58 * The handler hook needs to use the new registration system
60 * Modules. Which modules do not work yet, can we get a list?
62 * We need a thread-safe resolver, at least on Unix.
63 Status: The best known candidate would be something from
66 RELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP:
68 * "make distclean" leaves (at least these) turds:
71 lib/apr/shmem/unix/mm/config.log
72 lib/apr/shmem/unix/mm/mm_conf.h
73 lib/apr/shmem/unix/mm/libtool
74 lib/apr/shmem/unix/mm/config.status
75 lib/apr/shmem/unix/mm/Makefile
76 lib/apr/shmem/unix/mm/mm-config
82 * the top-level configure.in appears to use $USE_MAINTAINER_MODE = yes
83 to set -Wall/etc. flags, and the APR configure.in appears to use
84 --with-debug. both seem like more of a hardwired pain compaired
85 to the pre-2.0 method of setting EXTRA_CFLAGS.
87 * Win32: Reuse accept socket after transmitfile/close
88 This is not a bug, but would be nice to get this feature in
91 * Win32: Enable the winnt MPM to use the new scoreboard API
93 * Win32: Non-blocking CGI pipes
95 * Win32: Graceful restart of a service is broken (code does shutdown then start)
97 * Dynamically loadable MPMs
98 Enable users of the binary distributions of Apache to be able to
99 dynamically load the MPM.
101 Dean says this probably isn't a good idea. For example consider
102 -lpthread, you couldn't have the same core run with pthreads,
103 prefork, and gnu pth without a lot of headaches is my guess.
105 * Platforms that do not support fork (primarily Win32 and AS/400)
106 Consider introducing HAVE_FORK feature macro. Architect start-up code
107 that avoids initializing all the modules in the parent process on
108 platforms that do not support fork.
110 * Clean the code. There are a lot of places we used APR but didn't
111 remove the hacks that were required for the cross-platform code in
112 1.3. We need to make the code look like APR was supposed to be there.
114 * Go throught the 1.3 Bug DB and research the bugs marked "suspended".
115 People were told these would be considered for inclusion in Apache 2.0,
116 it would be nice to actually do so.
118 * Win32: Migrate the MPM over to use APR thread/process calls. This
119 would eliminate some code in the Win32 branch that essentially
120 duplicates what is in APR.
121 Status: Bill <stoddard@raleigh.ibm.com> is working on this.
123 * Move I/O layering into APR.
125 * There are still a number of places in the code where we are
126 loosing error status (i.e. throwing away the error returned by a
127 system call and replacing it with a generic error code)
129 * Win32: Implement reliable piped logs on Windows
130 Status: Bill <stoddard@raleigh.ibm.com> has prototype code (not
131 reliable) in 1.3. Should be much cleaner with APR in 2.0.
133 * Switch to autoconf, et al. for configuration.
134 Status: Manoj has placed an initial version into the 2.0
135 repository. Todos include:
137 - "make install" should work
138 - a tool to simplfy third-party module building should be
139 written. Something like apxs
140 - Add a lot more checks to satisfy the various platforms, e.g.
143 * Use APR to get rid of more platform dependancies.
144 Status: Ryan Bloom <rbb@raleigh.ibm.com> is working on this.
146 * The connection status table is not very efficient. Also, very few stats
147 are exported to the connection status table (easy to fix), and mod_status
150 Other bugs that need fixing:
152 * MaxRequestsPerChild measures connections, not requests.
153 Until someone has a better way, we'll probably just rename it
154 "MaxConnectionsPerChild".
156 * Regex containers don't work in an intutive way
157 Status: No one has come up with an efficient way to fix this
158 behavior. Dean has suggested getting rid of regex containers
161 * SIGSEGV on Linux (glibc 2.1.2) isn't caught properly by a
162 sigwaiting thread. We need to work around this, perhaps unless
163 there is hope soon for a fixed glibc.
165 Other features that need writing:
167 * Finish infrastructure in core for async MPMs
170 * TODO in source -- just do an egrep on "TODO" and see what's there
172 Documentation that needs writing:
174 * The concept of MPMs, especially if we ship more than one MPM for a
177 * New directives in the various MPMs and appropriate links from
178 obsolete directives in core.html to the MPM documentation.
180 * Revise manual/stopping.html and the last part of
181 manual/misc/perf-tuning.html to take account of the MPMs.
184 Status: Ben Laurie has written some hooks documentation
185 (apache-2.0/htdocs/hooks.html)
187 * Changes since 1.3.9 can be more easily seen in the commitlog file
188 dev.apache.org:/home/cvs/CVSROOT/commitlogs/apache-2.0
189 which includes some of Roy's comments when the changes were
190 committed in rough change-sets by purpose. Note that the commitlog
191 does not show the contents of new files until later.
195 * Mike Abbott's <mja@trudge.engr.sgi.com> patches to improve
197 Status: These were written for 1.3, and are awaiting a port to
202 * What do we do about mod_proxy?
204 * Which MPMs will be included with Apache 2.0?
206 * Is conf/highperformance.conf-dist obsolete? It looks obsolete.
