6 2.0a3 : vague plans to release in April sometime.
7 2.0a2 : released March 31, 2000
8 2.0a1 : released March 10, 2000
11 * Re-work configuration for top level Apache. Work should start with
12 trying to clean the autoconf stuff. If and only if this proves
13 impossible to do (very unlikely), autoconf should be removed and we
14 will roll our own config implementation.
15 NOTE: When this is implemented, it would be really nice if the
16 default cgi module on Unix with a threaded MPM is the cgid
17 module. This should be override-able of course.
18 Status: Jim Jagielski is looking into this.
20 * Put buffered file I/O back into APR. This should be done using the
21 buffering logic from the OS/2 directory. stdio FILE *'s should not be
22 used on Unix because of the limitations these impose on some platforms,
23 for example the 256 File * limit on Solaris.
26 see <Pine.LNX.4.21.0004101511380.7822-100000@twinlark.arctic.org>
28 * MPMs should have responsibility for closing sockets and
29 registering the socket cleanup. Stop registering multiple
30 cleanups for each socket. Move socket close code out of
31 http_connection.c and into the MPMs.
34 * Reliable piped logs look broken everywhere. Each MPM includes essentially
35 identical code to ap_register_other_child(), etc. Most of this code can
36 be moved out of the MPMs and into some common file (http_core.c?).
37 Dean says presumably you mean an os-specific file?
39 * Pipes to CGI scripts are not being timed out
40 Status: code has been added to APR to support timing out pipes.
41 This needs to be used in Apache now.
43 * Put back resource limit code
46 Status: Manoj has posted an patch to fix this.
47 <19991103003605.A20612@samosa.mindspring.com>
49 * Win32: Enable the Windows MPM to honor max_requests_per_child
50 Status: Bill will fix this.
52 * Win32: Get Apache working on Windows 95/98. The following work
53 (at least) needs to be done:
54 - winnt MPM: Fix 95/98 code paths in the winnt MPM. There is some NT
55 specific code that is still not in NT only code paths
56 - APR sendfile uses TransmitFile which is not available on
58 - ap_stat uses GetFileAttributeEx which is not available on
63 * Win32: Test access logging with multiple threads. Will the
64 native file I/O calls serialize automagically like the
65 CRT calls or do we need to add region locking each time
69 * Win32: Smoke test all ported modules to make sure they work
70 correctly under Windows.
73 * Current 2.0 code is not tested on many Unix platforms. Make 2.0
74 work on most, if not all the systems 1.3 did
75 Status: Autoconf and APR will get us most of the way there.
77 * The handler hook needs to use the new registration system
79 * Modules. Which modules do not work yet, can we get a list?
81 * We need a thread-safe resolver, at least on Unix.
82 Status: The best known candidate would be something from
85 RELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP:
86 * Configuration Modules. Allow a new module type that reads
87 a config file and sets up an internal tree structure for
90 * "make distclean" leaves (at least these) turds:
93 lib/apr/shmem/unix/mm/config.log
94 lib/apr/shmem/unix/mm/mm_conf.h
95 lib/apr/shmem/unix/mm/libtool
96 lib/apr/shmem/unix/mm/config.status
97 lib/apr/shmem/unix/mm/Makefile
98 lib/apr/shmem/unix/mm/mm-config
104 * the top-level configure.in appears to use $USE_MAINTAINER_MODE = yes
105 to set -Wall/etc. flags, and the APR configure.in appears to use
106 --with-debug. both seem like more of a hardwired pain compaired
107 to the pre-2.0 method of setting EXTRA_CFLAGS.
109 * Win32: Reuse accept socket after transmitfile/close
110 This is not a bug, but would be nice to get this feature in
113 * Win32: Enable the winnt MPM to use the new scoreboard API
115 * Win32: Non-blocking CGI pipes
117 * Win32: Graceful restart of a service is broken (code does shutdown then start)
119 * Dynamically loadable MPMs
120 Enable users of the binary distributions of Apache to be able to
121 dynamically load the MPM.
123 Dean says this probably isn't a good idea. For example consider
124 -lpthread, you couldn't have the same core run with pthreads,
125 prefork, and gnu pth without a lot of headaches is my guess.
127 * Platforms that do not support fork (primarily Win32 and AS/400)
128 Consider introducing HAVE_FORK feature macro. Architect start-up code
129 that avoids initializing all the modules in the parent process on
130 platforms that do not support fork.
132 * Clean the code. There are a lot of places we used APR but didn't
133 remove the hacks that were required for the cross-platform code in
134 1.3. We need to make the code look like APR was supposed to be there.
136 * Go throught the 1.3 Bug DB and research the bugs marked "suspended".
137 People were told these would be considered for inclusion in Apache 2.0,
138 it would be nice to actually do so.
140 * Win32: Migrate the MPM over to use APR thread/process calls. This
141 would eliminate some code in the Win32 branch that essentially
142 duplicates what is in APR.
144 Bill says we need a new procattr, APR_CREATE_SUSPENDED (or
145 something similar) to direct ap_create_process to create the
146 process suspended. We also need a call to wake up the suspended
147 process This may not be able to be implemented everywhere though.
151 * Move I/O layering into APR.
153 * There are still a number of places in the code where we are
154 loosing error status (i.e. throwing away the error returned by a
155 system call and replacing it with a generic error code)
157 * Win32: Implement reliable piped logs on Windows
160 * Switch to autoconf, et al. for configuration.
161 Status: Manoj has placed an initial version into the 2.0
162 repository. Todos include:
164 - "make install" should work
165 - a tool to simplfy third-party module building should be
166 written. Something like apxs
167 - Add a lot more checks to satisfy the various platforms, e.g.
170 * Use APR to get rid of more platform dependancies.
171 Status: Ryan Bloom <rbb@covalenet.net> is working on this.
173 * The connection status table is not very efficient. Also, very few stats
174 are exported to the connection status table (easy to fix), and mod_status
177 * Optimise the name-based <VirtualHost> implementation so that it uses
178 a hash table instead of a linear linked list scan.
180 * Mass vhosting version of suEXEC.
182 Other bugs that need fixing:
184 * MaxRequestsPerChild measures connections, not requests.
185 Until someone has a better way, we'll probably just rename it
186 "MaxConnectionsPerChild".
188 * Regex containers don't work in an intutive way
189 Status: No one has come up with an efficient way to fix this
190 behavior. Dean has suggested getting rid of regex containers
193 * SIGSEGV on Linux (glibc 2.1.2) isn't caught properly by a
194 sigwaiting thread. We need to work around this, perhaps unless
195 there is hope soon for a fixed glibc.
197 Other features that need writing:
199 * Finish infrastructure in core for async MPMs
202 * TODO in source -- just do an egrep on "TODO" and see what's there
204 Documentation that needs writing:
205 * Mod_status docs are needed.
207 * The concept of MPMs, especially if we ship more than one MPM for a
210 * New directives in the various MPMs and appropriate links from
211 obsolete directives in core.html to the MPM documentation.
213 * Revise manual/stopping.html and the last part of
214 manual/misc/perf-tuning.html to take account of the MPMs.
217 Status: Ben Laurie has written some hooks documentation
218 (apache-2.0/htdocs/hooks.html)
220 * Changes since 1.3.9 can be more easily seen in the commitlog file
221 dev.apache.org:/home/cvs/CVSROOT/commitlogs/apache-2.0
222 which includes some of Roy's comments when the changes were
223 committed in rough change-sets by purpose. Note that the commitlog
224 does not show the contents of new files until later.
228 * Mike Abbott's <mja@trudge.engr.sgi.com> patches to improve
230 Status: These were written for 1.3, and are awaiting a port to
235 * What do we do about mod_proxy?
237 * Which MPMs will be included with Apache 2.0?
239 * Is conf/highperformance.conf-dist obsolete? It looks obsolete.
