6 Vague plan, assuming more features aren't demanded for the 2.0 release
14 * MPMs should have responsibility for closing sockets and
15 registering the socket cleanup. Stop registering multiple
16 cleanups for each socket. Move socket close code out of
17 http_connection.c and into the MPMs.
20 * Reliable piped logs look broken everywhere. Each MPM includes essentially
21 identical code to ap_register_other_child(), etc. Most of this code can
22 be moved out of the MPMs and into some common file (http_core.c?).
24 * DSO hooks registered during the preflight call to ap_read_config
25 are not 'unregistered' during the preflight clean-up. Thus, when
26 Apache comes up, the hook tables contain two entries for each DSO hook,
27 one of which is bogus, leftover from the preflight.
29 * Pipes to CGI scripts are not being timed out
30 Status: code has been added to APR to support timing out pipes.
31 This needs to be used in Apache now.
33 * Put back resource limit code
36 Status: Paul Reder <rederpj@raleigh.ibm.com> is working on this.
39 Status: Manoj has posted an patch to fix this.
40 <19991103003605.A20612@samosa.mindspring.com>
42 * Win32: Enable the Windows MPM to honor max_requests_per_child
43 Status: Bill will fix this.
45 * Win32: Fix Win9* specific code in the winnt MPM
48 * Win32: Test access logging with multiple threads. Will the
49 native file I/O calls serialize automagically like the
50 CRT calls or do we need to add region locking each time
54 * Win32: Smoke test all ported modules to make sure they work
55 correctly under Windows.
58 * Current 2.0 code is not tested on many Unix platforms. Make 2.0
59 work on most, if not all the systems 1.3 did
60 Status: Autoconf and APR will get us most of the way there.
62 * The module API is a weird combination of the old table and the new
63 hook system. Switch completely to the new hook system
64 Status: Ben Laurie is working on this.
66 * Modules. Which modules do not work yet, can we get a list?
68 * We need a thread-safe resolver, at least on Unix.
69 Status: The best known candidate would be something from BIND
70 (v8 or v9?) The only other option would be to mutex all the
73 RELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP:
75 * "make distclean" leaves (at least these) turds:
78 lib/apr/shmem/unix/mm/config.log
79 lib/apr/shmem/unix/mm/mm_conf.h
80 lib/apr/shmem/unix/mm/libtool
81 lib/apr/shmem/unix/mm/config.status
82 lib/apr/shmem/unix/mm/Makefile
83 lib/apr/shmem/unix/mm/mm-config
89 * Win32: Reuse accept socket after transmitfile/close
90 This is not a bug, but would be nice to get this feature in
93 * Win32: Enable the winnt MPM to use the new scoreboard API
95 * Win32: Non-blocking CGI pipes
97 * Win32: Graceful restart of a service is broken (code does shutdown then start)
99 * Dynamically loadable MPMs
100 Enable users of the binary distributions of Apache to be able to
101 dynamically load the MPM.
103 * Platforms that do not support fork (primarily Win32 and AS/400)
104 Consider introducing HAVE_FORK feature macro. Architect start-up code
105 that avoids initializing all the modules in the parent process on
106 platforms that do not support fork.
108 * Clean the code. There are a lot of places we used APR but didn't
109 remove the hacks that were required for the cross-platform code in
110 1.3. We need to make the code look like APR was supposed to be there.
112 * Go throught the Bug DB and research the bugs marked "suspended". People
113 were told these would be considered for inclusion in Apache 2.0, it
114 would be nice to actually do so.
116 * Win32: Migrate the MPM over to use APR thread/process calls. This
117 would eliminate some code in the Win32 branch that essentially
118 duplicates what is in APR.
119 Status: Bill <stoddard@raleigh.ibm.com> is working on this.
121 * Move I/O layering into APR.
123 * There are still a number of places in the code where we are
124 loosing error status (i.e. throwing away the error returned by a
125 system call and replacing it with a generic error code)
127 * Win32: Implement reliable piped logs on Windows
128 Status: Bill <stoddard@raleigh.ibm.com> has prototype code (not
129 reliable) in 1.3. Should be much cleaner with APR in 2.0.
131 * Switch to autoconf, et al. for configuration.
132 Status: Manoj has placed an initial version into the 2.0
133 repository. Todos include:
135 - "make install" should work
136 - a tool to simplfy third-party module building should be
137 written. Something like apxs
138 - Add a lot more checks to satisfy the various platforms, e.g.
141 * Use APR to get rid of more platform dependancies.
142 Status: Ryan Bloom <rbb@raleigh.ibm.com> is working on this.
144 * The connection status table is not very efficient. Also, very few stats
145 are exported to the connection status table (easy to fix), and mod_status
148 Other bugs that need fixing:
150 * MaxRequestsPerChild measures connections, not requests.
151 Until someone has a better way, we'll probably just rename it
152 "MaxConnectionsPerChild".
154 * Regex containers don't work in an intutive way
155 Status: No one has come up with an efficient way to fix this
156 behavior. Dean has suggested getting rid of regex containers
159 * SIGSEGV on Linux (glibc 2.1.2) isn't caught properly by a
160 sigwaiting thread. We need to work around this, perhaps unless
161 there is hope soon for a fixed glibc.
163 Other features that need writing:
165 * Finish infrastructure in core for async MPMs
168 * TODO in source -- just do an egrep on "TODO" and see what's there
170 * Work on other MPMs. Possible MPMs discussed or in progress include:
172 - Dean Gaudet's async MPM
173 Status: dean is unlikely to begin work on this any time soon...
174 has lots of ideas he'll share with folks willing to begin
175 tackling the issues. this is apache 2.1 material.
177 - Zach Brown's <zab@zabbo.net> Linux siginfo MPM
180 Documentation that needs writing:
182 * The concept of MPMs, especially if we ship more than one MPM for a
185 * New directives in the various MPMs
188 Status: Ben Laurie has written some hooks documentation
189 (apache-2.0/htdocs/hooks.html)
191 * Changes since 1.3.9 can be more easily seen in the commitlog file
192 dev.apache.org:/home/cvs/CVSROOT/commitlogs/apache-2.0
193 which includes some of Roy's comments when the changes were
194 committed in rough change-sets by purpose. Note that the commitlog
195 does not show the contents of new files until later.
199 * Mike Abbott's <mja@trudge.engr.sgi.com> patches to improve
201 Status: These were written for 1.3, and are awaiting a port to
206 * What do we do about mod_proxy?
208 * Which MPMs will be included with Apache 2.0?
210 * Is conf/highperformance.conf-dist obsolete? It looks obsolete.
