37 Please consult the following STATUS files for information
41 * srclib/apr-util/STATUS
45 CURRENT RELEASE NOTES:
47 * 34 status: Let's get all API changes and showstoppers in this one.
50 FINAL RELEASE SHOWSTOPPERS:
52 * If any request gets to the core handler, without a flag that this
53 r->filename was tested by dir/file_walk, we need to 500 at the very
54 end of the ap_process_request_internal() processing. This provides
55 authors of older modules better compatibility, while still improving
56 the security and robustness of 2.0.
57 Status: still need to decide where this goes, OtherBill comments...
58 Message-ID: <065701c14526$495203b0$96c0b0d0@roweclan.net>
59 we need to look at halting this in the 'default handler' case,
60 and that implies pushing the 'handler election' into the request
61 internal processing phase from the run request phase.
62 Jim asks: would a stopgap be something bogus like adding another
63 flag to request_rec ala eos_sent and before we OK, if not set
66 * We need to find out the right place to add the AddOutputFilterByType
67 directive. mod_mime? No. core with fixups? That's what it is now.
68 ap_pass_brigade() hook? As a filter that runs at HTTP_HEADER stage?
69 This needs to be resolved before the next public release.
70 Message-ID: <018701c1b99c$f0f24310$0a01230a@KOJ>
72 * API changes planned for 2.0 that should happen before the
74 * Free lists for bucket allocation
75 * Pool allocator change
77 * We do not properly substitute the prefix-variables in the configuration
78 scripts or generated-configs. (i.e. if sysconfdir is etc,
79 httpd-std.conf points to conf.)
82 * Win32 doesn't install as service correctly [9863, 9914, 9961]
83 * Don't be stupid and cd to a blank directory when doing installs
88 * Should we always build binaries statically unless otherwise
90 Message-ID: <20020129210006.B23512@Lithium.MeepZor.Com>
95 * If the parent process dies, should the remaining child processes
96 "gracefully" self-terminate. Or maybe we should make it a runtime
97 option, or have a concept of 2 parent processes (one being a
99 See: Message-ID: <3C58232C.FE91F19F@Golux.Com>
101 Self-destruct: Ken, Martin
102 Not self-destruct: BrianP, Ian, Cliff, BillS
103 Make it runtime configurable: Aaron, Jim, Justin
104 Have 2 parents: +1: Jim
106 +0: Martin (while standing by, could it do
109 * Make the worker MPM the default MPM for threaded Unix boxes.
110 +1: Justin, Ian, Cliff
111 -0: Aaron (premature decision, needs more discussion), Lars
113 RELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP:
115 * Convert all instances of the old apr_lock_t type to the new
117 Status: Aaron has converted all but the perchild MPM to
118 use the new lock API. Since perchild has been put
119 on the back burner, this is no longer a showstopper.
120 Aaron will patch perchild as soon as it becomes
123 * With AP_MODE_EXHAUSTIVE in the core, it is finally clear to me
124 how the Perchild MPM should be re-written. It hasn't worked
125 correctly since filters were added because it wasn't possible to
126 get the content that had already been written and the socket at
127 the same time. This mode lets us do that, so the MPM can be
130 * htpasswd blindly processes the file you give it, and does no
131 sanity checking before totally corrupting whatever file it was
132 you thought you had. It should check the input file and bail
133 if it finds non-comment lines that do not contain exactly 1
135 Message-ID: <20020217150457.A31632@clove.org>
137 * Can a static httpd be built reliably?
138 Message-ID: <20020207142751.T31582@clove.org>
140 * [Ken] Test suite failures:
141 o worker is also failing some of the 'cgi' subtests
142 (see <URL:http://Source-Zone.Org/Apache/regression/>):
143 Justin says: "Worker should be fine and passes httpd-test here.
144 If you can provide evidence that it can be reproduced
145 outside of httpd-test, then it's a showstopper. I
146 think it's a perl or a httpd-test problem."
147 Not a showstopper: Justin
149 * Usage of APR_BRIGADE_NORMALIZE in core_input_filter should be
151 Message-ID: <Pine.LNX.4.33.0201202232430.318-100000@deepthought.cs.virginia.edu>
153 * There is a bug in how we sort some hooks, at least the pre-config
154 hook. The first time we call the hooks, they are in the correct
155 order, but the second time, we don't sort them correctly. Currently,
156 the modules/http/config.m4 file has been renamed to
157 modules/http/config2.m4 to work around this problem, it should moved
158 back when this is fixed. rbb
159 Justin says: "Is this really a showstopper? This has been here
160 forever. What's wrong? Does this have to do with
162 Not a showstopper: Justin, BrianP, trawick, gregames
164 * The Add...Filter and Set...Filter directives do not allow the
165 administrator to order filters, beyond the order of filename (mime)
166 extensions. It isn't clear if Set...Filter(s) should be inserted
167 before or after the Add...Filter(s) which are ordered by sequence of
168 filename extensions. At minimum, some sort of +-[0-10] syntax seems
169 like the quickest fix for a 2.0 gold release.
170 Justin says: "Could we delay this for a point release or 2.1?"
171 Not a showstopper: justin, wrowe, trawick, stoddard, Jim, Ian, Aaron,
174 * Get perchild to work on platforms other than Linux. This
175 will require a portable mechanism to pass data and file/socket
176 descriptors between vhost child groups. An API was proposed
178 Message-ID: <20020111115006.K1529@clove.org>
180 * CGI single-byte reads
181 BrianP suggests that this is caused by the ap_scan_script_header_err()
182 routine, which will do single-byte reads until it finds the end
183 of the header, at which point it constructs a pipe-bucket (buffered)
185 Proposed solution in:
186 Message-ID: <3C36ADAF.60601@cnet.com>
188 * Try to get libtool inter-library dependency code working on AIX.
189 Message-ID: <cm3n10lx555.fsf@rdu163-40-092.nc.rr.com>
191 Justin says: If we get it working on AIX, we can enable this
192 on all platforms and clean up our build system
194 Jeff says: I thought I tested a patch for you sometime in
195 January that you were going to commit within a few
198 * Handling of %2f in URIs. Currently both 1.3 and 2.0
199 completely disallow %2f in the request URI path (see
200 ap_unescape_url() in util.c). It's permitted and passed
201 through in the query string, however. Roy says the
202 original reason for disallowing it, from five years ago,
203 was to protect CGI scripts that applied PATH_INFO to
204 a filesystem location and which might be tricked by
205 ..%2f..%2f(...). We *should* allow path-info of the
206 form 'http://foo.com/index.cgi/path/to/path%2finfo'.
207 Since we've revamped a lot of our processing of path
208 segments, it would be nice to allow this, or at least
209 allow it conditionally with a directive.
211 * FreeBSD, threads, and worker MPM. All seems to work fine
212 if you only have one worker process with many threads. Add
213 a second worker process and the accept lock seems to be
214 lost. This might be an APR issue with how it deals with
215 the child_init hook (i.e. the fcntl lock needs to be resynced).
216 More examination and analysis is required.
217 Status: This has also been reported on Cygwin.
218 Message-ID: <3C2CC514.8EF3BED1@wapme-systems.de> (cygnus)
220 Justin says: So, FreeBSD-CURRENT and Cywin have the same
221 problem. Yum. If another platform has this
222 with worker, this becomes a showstopper.
223 Aaron says: I spent some time disecting this and have come to
224 the conclusion that it is not a problem in the worker MPM
225 (or at least, it is not isolated to a problem in worker).
226 I'll list some of the problems I'm seeing in case someone
227 else wants to pick up where I've left off:
228 - Delivery of just about any signal to one of the child
229 processes will send it into an infinite loop as well.
230 - Even though the parent is spinning out of control,
231 at first the child or children will appear to work
232 properly. At times it is possible to get it into a state,
233 however, where a request will hang until another concurrent
234 request "kicks" the first, at which point the second will
235 hang. My theory is that this has to do with the
236 pthread_cond_*() implementation in FreeBSD, but it's still
237 possible that it is in APR.
239 Justin adds: Oh, FreeBSD threads are implemented entirely with
240 select()/poll()/longjmp(). Welcome to the nightmare.
241 So, that means a ktrace output also has the thread
242 scheduling internals in it (since it is all the same to
243 the kernel). Which makes it hard to distinguish between
244 our select() calls and their select() calls.
245 *bangs head on wall repeatedly* But, some of the libc_r
246 files have a DBG_MSG #define. This is moderately helpful
247 when used with -DNO_DETACH. The kernel scheduler isn't
248 waking up the threads on a select(). Yum. And, I bet
249 those decrementing select calls have to do with the
250 scheduler. Time to brush up on our OS fundamentals.
252 * There is increasing demand from module writers for an API
253 that will allow them to control the server à la apachectl.
254 Reasons include sole-function servers that need to die if
255 an external dependency (e.g., a database) fails, et cetera.
256 Perhaps something in the (ever more abused) scoreboard?
257 rbb: I don't believe the scoreboard is the correct mechanism
258 for this. We already have a pipe that goes between parent
259 and child for graceful shutdown events, along with an API that
260 can be used to send a message down that pipe. In threaded MPMs,
261 it is easy enough to make that one pipe be used for graceful
262 and graceless events, and it is also easy to open that pipe
263 to both parent and child for writing. Then we just need to
264 figure out how to do graceless on non-threaded MPMs.
266 * Allow the DocumentRoot directive within <Location > scopes? This
267 allows the beloved (crusty) Alias /foo/ /somepath/foo/ followed
268 by a <Directory /somepath/foo> to become simply
269 <Location /foo/> DocumentRoot /somefile/foo (IMHO a bit more legible
270 and in-your-face.) DocumentRoot unset would be accepted [and would
271 not permit content to be served, only virtual resources such as
272 server-info or server-status.
273 This proposed change would _not_ depricate Alias.
275 * Win32: Rotatelogs sometimes is not terminated when Apache
276 goes down hard. FirstBill was looking at possibly tracking the
277 child's-child processes in the parent process.
278 OtherBill asks, wasn't this fixed?
279 stoddard: Not fixed. Shared scoreboard might offer a good
280 way for the parent to keep track of 'other child' processes
281 and whack them if the child goes down.
283 * Win32: Add a simple hold console open patch (wait for close or
284 the ESC key, with a nice message) if the server died a bad
285 death (non-zero exit code) in console mode.
286 Resolution: bring forward same ugly hacks from 1.3.13-.20
288 * Port of mod_ssl to Apache 2.0:
290 The current porting state is summarized in modules/ssl/README. The
291 remaining work includes:
292 (1) stablizing/optimizing the SSL filter logic
293 (2) Enabling the various SSL caching mechanisms (shmcb, shmht)
294 (3) Enabling SSL extentions
295 (4) Trying to seperate the https filter logic from mod_ssl -
296 This is to facilitate other modules that wish to use the https
297 filter or the mod_ssl logic or both as required.
298 Justin: mod_ssl filter logic is redone, so that should be fine.
299 Madhu has submitted a patch for SSL caching - however, I
300 am -0 on that patch as I *think* we could implement the
301 shared memory another way that is much cleaner (i.e.
302 treat shmem directly as a dbm via APR routines). Justin
303 also thinks that the https filter logic may be sufficiently
304 decoupled now, but isn't really sure.
306 * Performance & Debug: Eliminate most (and perhaps all) of the
307 malloc/free calls in the bucket brigade code. Need some
308 light weight memory management functions that allow freeing
309 memory (putting it back into a memory pool) when it is no
310 longer needed. Enabling simple debugging features like guard
311 bands, double free detection, etc. would be cool but certainly
312 not a hard requirement.
314 Status: Cliff started to implement this using SMS as has
315 been discussed at length for months, but since
316 SMS is not being used anywhere else in the server,
317 several people expressed the opinion that we should
318 get rid of it entirely, meaning that the buckets
319 need their own memory management (free list) functions.
320 Cliff will implement that this weekend so we at least
321 have something to look at/compare with.
323 * Eliminate unnecessary creation of pipes in mod_cgid
324 Status: Ken asks, didn't Jeff fix this when he fixed the queue
327 * Combine log_child and piped_log_spawn. Clean up http_log.c.
330 * Document mod_file_cache.
332 * Platforms that do not support fork (primarily Win32 and AS/400)
333 Architect start-up code that avoids initializing all the modules
334 in the parent process on platforms that do not support fork.
336 * Win32: Migrate the MPM over to use APR thread/process calls. This
337 would eliminate some code in the Win32 branch that essentially
338 duplicates what is in APR.
340 * There are still a number of places in the code where we are
341 losing error status (i.e. throwing away the error returned by a
342 system call and replacing it with a generic error code)
344 * Mass vhosting version of suEXEC.
346 * All DBMs suffer from confusion in support/dbmmanage (perl script) since
347 the dbmmanage employs the first-matched dbm format. This is not
348 necessarily the library that Apache was built with. Aught to
349 rewrite dbmmanage upon installation to bin/ with the proper library
350 for predictable mod_auth_dbm administration.
351 Questions; htdbm exists, time to kill dbmmanage, or does it remain
352 useful as a perl dbm management example? If we keep it,
353 do we address the issue above?
356 Some additional items remaining:
357 - case_preserved_filename stuff
358 (use the new canonical name stuff?)
359 - find a new home for ap_text(_header)
360 - is it possible to remove the DAV: namespace stuff from util_xml?
362 * ap_core_translate() and its use by mod_mmap_static and mod_file_cache
363 are a bit wonky. The function should probably be exposed as a utility
364 function (such as ap_translate_url2fs() or ap_validate_fs_url() or
365 something). Another approach would be a new hook phase after
366 "translate" which would allow the module to munge what the
367 translation has decided to do.
368 Status: Greg +1 (volunteers), Ryan +1
370 * Explore use of a post-config hook for the code in http_main.c which
371 calls ap_fixup_virutal_hosts(), ap_fini_vhost_config(), and
372 ap_sort_hooks() [to reduce the logic in main()]
374 * read the config tree just once, and process N times (as necessary)
376 * (possibly) use UUIDs in mod_unique_id and/or mod_usertrack
378 * (possibly) port the bug fix for PR 6942 (segv when LoadModule is put
379 into a VirtualHost container) to 2.0.
381 * shift stuff to mod_core.h
383 * callers of ap_run_create_request() should check the return value
384 for failure (Doug volunteers)
386 * Win32: Get Apache working on Windows 95/98. The following work
387 (at least) needs to be done:
388 - Document warning that OSR2 is required (for Crypt functions, in
389 rand.c, at least.) This could be resolved with an SSL library, or
390 randomization in APR itself.
391 - Bring the Win9xConHook.dll from 1.3 into 2.0 (no sense till it
392 actually works) and add in a splash of Win9x service code.
394 * In order to use a DSO version of mod_ssl we have to link with
395 -lssl and -lcrypto. A workaround is in place right now where the
396 entire EXTRA_LIBS macro is being appended to the objects list, but
397 this is a hack. We should either revamp the APACHE_CHECK_SSL_TOOLKIT
398 autoconf function or come up with some other autoconf checks to
399 search for libssl and libcrypto and properly add them to mod_ssl's
402 * Fix the worker MPM to use POD to kill child processes instead
403 of ap_os_killpg, regardless of how they should die. (Ryan Bloom)
405 * mod_cache: handle cache_control: no_cache "field_name" to enable
406 cacheing the response w/o header "field_name"

748 Need to be able to override shebang line to make CGI scripts
753 "Files" and "FilesMatch" regexp does not recognize bang as
757 * PR#4448: mod_log-any
758 Please allow CGI env variables (QUERY_STRING, ...) to be logged
762 * PR#4459: mod_include
763 Suggestion for better handling of Last-modified headers
767 mod_cgi prevents handling of OPTIONS requests
770 * PR#5713: os-windows
771 [PATCH] install as win32 service with domain account
772 Status: Cannot accept password-as-arg, we should prompt the
773 user when -k install/-k config with a user argument.
776 AllowOverride should have a 'CheckNone' and 'AllowNone' argument
777 instead of only 'None'
780 Other bugs that need fixing:
782 * MaxRequestsPerChild measures connections, not requests.
783 Until someone has a better way, we'll probably just rename it
784 "MaxConnectionsPerChild".
786 * Regex containers don't work in an intutive way
787 Status: No one has come up with an efficient way to fix this
788 behavior. Dean has suggested getting rid of regex containers
790 OtherBill suggests: We at least seem to agree on eliminating
791 the <Container ~ foo> forms, and using only
792 <ContainerMatch foo> semantics.
794 * SIGSEGV on Linux (glibc 2.1.2) isn't caught properly by a
795 sigwaiting thread. We need to work around this, perhaps unless
796 there is hope soon for a fixed glibc.
798 * orig_ct in the byterange/multipart handling may not be
799 needed. Apache 1.3 just never stashed "multipart" into
800 r->content_type. We should probably follow suit since the
801 byterange stuff doesn't want the rest of the code to see the
802 multipart content-type; the other code should still think it is
803 dealing with the <orig_ct> stuff.
804 Status: Greg volunteers to investigate (esp. since he was most
805 likely the one to break it :-)
807 Other features that need writing:
809 * Finish infrastructure in core for async MPMs
812 * TODO in source -- just do an egrep on "TODO" and see what's there
816 * Jon Travis's <jtravis@covalent.net> patch to deal with thread-safe
817 issues with inet_ntoa. See message <20001201163220.A12827@covalent.net>
818 Status: This is being set aside until the IPv6 work is finished
819 so that we know exactly what is required.
821 * Martin Sojka <msojka@gmx.de>'s patch to add error reporting for failed
822 htpasswd actions due to a full /tmp volume (other programs may have
827 * Mike Abbott's <mja@trudge.engr.sgi.com> patches to improve
829 Status: These were written for 1.3, and are awaiting a port to
832 * Jim Winstead's <jimw@trainedmonkey.com> patch to add CookieDomain and
833 other small mod_usertrack features
835 * Dan Rench's <drench@xnet.com> patch to add allow the errmsg and timefmt
836 of SSI's to be modified in the config file. Patch is available in
841 * Which MPMs will be included with Apache 2.0?
