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$96c0b0d0@roweclan.net>
59 we need to look at halting this in the 'default handler' case,
60 and that implies pushing the 'handler election' into the request
61 internal processing phase from the run request phase.
62 Jim asks: would a stopgap be something bogus like adding another
63 flag to request_rec ala eos_sent and before we OK, if not set
65 Jeff says: reviewing the original message and the one
66 follow-up (also from OtherBill) it looks like OtherBill had a
67 good handle on the problem, though I wonder why not just put a
68 simple check in default_handler to see if dir/file_walk has
69 been done (a footprint left by dir/file_walk doesn't have to
70 be in request_rec; a better place is core_request_config)
72 * We need to find out the right place to add the AddOutputFilterByType
73 directive. mod_mime? No. core with fixups? That's what it is now.
74 ap_pass_brigade() hook? As a filter that runs at HTTP_HEADER stage?
75 This needs to be resolved before the next public release.
76 Message-ID: <018701c1b99c$f0f24310$0a01230a@KOJ>
77 BillS is working on this...
79 * API changes planned for 2.0 that should happen before the
81 * Free lists for bucket allocation
83 * We do not properly substitute the prefix-variables in the configuration
84 scripts or generated-configs. (i.e. if sysconfdir is etc,
85 httpd-std.conf points to conf.)
86 Aaron says: This is not a showstopper, these problems have existed
87 for as long as I can remember. It would be nice to fix
88 them but they are not new.
91 * Win32 doesn't install as service correctly [9863, 9914, 9961]
93 * Don't forget to reversion mod_ssl, which is currently listed
98 * Should we always build binaries statically unless otherwise
100 Message-ID: <20020129210006.B23512@Lithium.MeepZor.Com>
105 * If the parent process dies, should the remaining child processes
106 "gracefully" self-terminate. Or maybe we should make it a runtime
107 option, or have a concept of 2 parent processes (one being a
109 See: Message-ID: <3C58232C.FE91F19F@Golux.Com>
111 Self-destruct: Ken, Martin
112 Not self-destruct: BrianP, Ian, Cliff, BillS
113 Make it runtime configurable: Aaron, Jim, Justin
114 Have 2 parents: +1: Jim
116 +0: Martin (while standing by, could it do
119 * Make the worker MPM the default MPM for threaded Unix boxes.
120 +1: Justin, Ian, Cliff
121 -0: Aaron (premature decision, needs more discussion), Lars
123 RELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP:
125 * Convert all instances of the old apr_lock_t type to the new
127 Status: Aaron has converted all but the perchild MPM to
128 use the new lock API. Since perchild has been put
129 on the back burner, this is no longer a showstopper.
130 Aaron will patch perchild as soon as it becomes
133 * With AP_MODE_EXHAUSTIVE in the core, it is finally clear to me
134 how the Perchild MPM should be re-written. It hasn't worked
135 correctly since filters were added because it wasn't possible to
136 get the content that had already been written and the socket at
137 the same time. This mode lets us do that, so the MPM can be
140 * htpasswd blindly processes the file you give it, and does no
141 sanity checking before totally corrupting whatever file it was
142 you thought you had. It should check the input file and bail
143 if it finds non-comment lines that do not contain exactly 1
145 Message-ID: <20020217150457.A31632@clove.org>
147 * Can a static httpd be built reliably?
148 Message-ID: <20020207142751.T31582@clove.org>
150 * [Ken] Test suite failures:
151 o worker is also failing some of the 'cgi' subtests
152 (see <URL:http://Source-Zone.Org/Apache/regression/>):
153 Justin says: "Worker should be fine and passes httpd-test here.
154 If you can provide evidence that it can be reproduced
155 outside of httpd-test, then it's a showstopper. I
156 think it's a perl or a httpd-test problem."
157 Not a showstopper: Justin
159 * Usage of APR_BRIGADE_NORMALIZE in core_input_filter should be
161 Message-ID: <Pine.LNX.4.33.0201202232430.318-100000@deepthought.cs.virginia.edu>
163 * There is a bug in how we sort some hooks, at least the pre-config
164 hook. The first time we call the hooks, they are in the correct
165 order, but the second time, we don't sort them correctly. Currently,
166 the modules/http/config.m4 file has been renamed to
167 modules/http/config2.m4 to work around this problem, it should moved
168 back when this is fixed. rbb
169 Justin says: "Is this really a showstopper? This has been here
170 forever. What's wrong? Does this have to do with
172 Not a showstopper: Justin, BrianP, trawick, gregames
174 * The Add...Filter and Set...Filter directives do not allow the
175 administrator to order filters, beyond the order of filename (mime)
176 extensions. It isn't clear if Set...Filter(s) should be inserted
177 before or after the Add...Filter(s) which are ordered by sequence of
178 filename extensions. At minimum, some sort of +-[0-10] syntax seems
179 like the quickest fix for a 2.0 gold release.
180 Justin says: "Could we delay this for a point release or 2.1?"
181 Not a showstopper: justin, wrowe, trawick, stoddard, Jim, Ian, Aaron,
184 * Get perchild to work on platforms other than Linux. This
185 will require a portable mechanism to pass data and file/socket
186 descriptors between vhost child groups. An API was proposed
188 Message-ID: <20020111115006.K1529@clove.org>
190 * CGI single-byte reads
191 BrianP suggests that this is caused by the ap_scan_script_header_err()
192 routine, which will do single-byte reads until it finds the end
193 of the header, at which point it constructs a pipe-bucket (buffered)
195 Proposed solution in:
196 Message-ID: <3C36ADAF.60601@cnet.com>
198 * Try to get libtool inter-library dependency code working on AIX.
199 Message-ID: <cm3n10lx555.fsf@rdu163-40-092.nc.rr.com>
201 Justin says: If we get it working on AIX, we can enable this
202 on all platforms and clean up our build system
204 Jeff says: I thought I tested a patch for you sometime in
205 January that you were going to commit within a few
208 * Handling of %2f in URIs. Currently both 1.3 and 2.0
209 completely disallow %2f in the request URI path (see
210 ap_unescape_url() in util.c). It's permitted and passed
211 through in the query string, however. Roy says the
212 original reason for disallowing it, from five years ago,
213 was to protect CGI scripts that applied PATH_INFO to
214 a filesystem location and which might be tricked by
215 ..%2f..%2f(...). We *should* allow path-info of the
216 form 'http://foo.com/index.cgi/path/to/path%2finfo'.
217 Since we've revamped a lot of our processing of path
218 segments, it would be nice to allow this, or at least
219 allow it conditionally with a directive.
221 * FreeBSD, threads, and worker MPM. All seems to work fine
222 if you only have one worker process with many threads. Add
223 a second worker process and the accept lock seems to be
224 lost. This might be an APR issue with how it deals with
225 the child_init hook (i.e. the fcntl lock needs to be resynced).
226 More examination and analysis is required.
227 Status: This has also been reported on Cygwin.
228 Message-ID: <3C2CC514.8EF3BED1@wapme-systems.de> (cygnus)
230 Justin says: So, FreeBSD-CURRENT and Cywin have the same
231 problem. Yum. If another platform has this
232 with worker, this becomes a showstopper.
233 Aaron says: I spent some time disecting this and have come to
234 the conclusion that it is not a problem in the worker MPM
235 (or at least, it is not isolated to a problem in worker).
236 I'll list some of the problems I'm seeing in case someone
237 else wants to pick up where I've left off:
238 - Delivery of just about any signal to one of the child
239 processes will send it into an infinite loop as well.
240 - Even though the parent is spinning out of control,
241 at first the child or children will appear to work
242 properly. At times it is possible to get it into a state,
243 however, where a request will hang until another concurrent
244 request "kicks" the first, at which point the second will
245 hang. My theory is that this has to do with the
246 pthread_cond_*() implementation in FreeBSD, but it's still
247 possible that it is in APR.
249 Justin adds: Oh, FreeBSD threads are implemented entirely with
250 select()/poll()/longjmp(). Welcome to the nightmare.
251 So, that means a ktrace output also has the thread
252 scheduling internals in it (since it is all the same to
253 the kernel). Which makes it hard to distinguish between
254 our select() calls and their select() calls.
255 *bangs head on wall repeatedly* But, some of the libc_r
256 files have a DBG_MSG #define. This is moderately helpful
257 when used with -DNO_DETACH. The kernel scheduler isn't
258 waking up the threads on a select(). Yum. And, I bet
259 those decrementing select calls have to do with the
260 scheduler. Time to brush up on our OS fundamentals.
262 * There is increasing demand from module writers for an API
263 that will allow them to control the server à la apachectl.
264 Reasons include sole-function servers that need to die if
265 an external dependency (e.g., a database) fails, et cetera.
266 Perhaps something in the (ever more abused) scoreboard?
267 rbb: I don't believe the scoreboard is the correct mechanism
268 for this. We already have a pipe that goes between parent
269 and child for graceful shutdown events, along with an API that
270 can be used to send a message down that pipe. In threaded MPMs,
271 it is easy enough to make that one pipe be used for graceful
272 and graceless events, and it is also easy to open that pipe
273 to both parent and child for writing. Then we just need to
274 figure out how to do graceless on non-threaded MPMs.
276 * Allow the DocumentRoot directive within <Location > scopes? This
277 allows the beloved (crusty) Alias /foo/ /somepath/foo/ followed
278 by a <Directory /somepath/foo> to become simply
279 <Location /foo/> DocumentRoot /somefile/foo (IMHO a bit more legible
280 and in-your-face.) DocumentRoot unset would be accepted [and would
281 not permit content to be served, only virtual resources such as
282 server-info or server-status.
283 This proposed change would _not_ depricate Alias.
285 * Win32: Rotatelogs sometimes is not terminated when Apache
286 goes down hard. FirstBill was looking at possibly tracking the
287 child's-child processes in the parent process.
288 OtherBill asks, wasn't this fixed?
289 stoddard: Not fixed. Shared scoreboard might offer a good
290 way for the parent to keep track of 'other child' processes
291 and whack them if the child goes down.
293 * Win32: Add a simple hold console open patch (wait for close or
294 the ESC key, with a nice message) if the server died a bad
295 death (non-zero exit code) in console mode.
296 Resolution: bring forward same ugly hacks from 1.3.13-.20
298 * Port of mod_ssl to Apache 2.0:
300 The current porting state is summarized in modules/ssl/README. The
301 remaining work includes:
302 (1) stablizing/optimizing the SSL filter logic
303 (2) Enabling SSL extentions
304 (3) Trying to seperate the https filter logic from mod_ssl -
305 This is to facilitate other modules that wish to use the https
306 filter or the mod_ssl logic or both as required.
308 * Performance & Debug: Eliminate most (and perhaps all) of the
309 malloc/free calls in the bucket brigade code. Need some
310 light weight memory management functions that allow freeing
311 memory (putting it back into a memory pool) when it is no
312 longer needed. Enabling simple debugging features like guard
313 bands, double free detection, etc. would be cool but certainly
314 not a hard requirement.
316 Status: Cliff started to implement this using SMS as has
317 been discussed at length for months, but since
318 SMS is not being used anywhere else in the server,
319 several people expressed the opinion that we should
320 get rid of it entirely, meaning that the buckets
321 need their own memory management (free list) functions.
322 Cliff will implement that this weekend so we at least
323 have something to look at/compare with.
325 * Eliminate unnecessary creation of pipes in mod_cgid
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"
407 See RFC2616 section 14.9.1
409 * Scoreboard structures could be changed in the future such that
410 proper alignment is not maintained, leading to segfaults on
411 some systems. Cliff posted a patch to deal with this issue but
412 later recanted. See this message to dev@apr.apache.org:

730 cannot limit some HTTP methods
733 * PR#3143: apache-api
734 No module specific data hook for per-connection data
737 * PR#3191: mod_negotiation
738 no way to set global quality-of-source (qs) coneg values
743 Accessing URL through proxy server corrupts data.
747 Some anonymous FTP URLs ask for authentication
751 New ErrorDocumentMatch directive
755 Need to be able to override shebang line to make CGI scripts
760 "Files" and "FilesMatch" regexp does not recognize bang as
764 * PR#4448: mod_log-any
765 Please allow CGI env variables (QUERY_STRING, ...) to be logged
769 * PR#4459: mod_include
770 Suggestion for better handling of Last-modified headers
774 mod_cgi prevents handling of OPTIONS requests
777 * PR#5713: os-windows
778 [PATCH] install as win32 service with domain account
779 Status: Cannot accept password-as-arg, we should prompt the
780 user when -k install/-k config with a user argument.
783 AllowOverride should have a 'CheckNone' and 'AllowNone' argument
784 instead of only 'None'
787 Other bugs that need fixing:
789 * MaxRequestsPerChild measures connections, not requests.
790 Until someone has a better way, we'll probably just rename it
791 "MaxConnectionsPerChild".
793 * Regex containers don't work in an intutive way
794 Status: No one has come up with an efficient way to fix this
795 behavior. Dean has suggested getting rid of regex containers
797 OtherBill suggests: We at least seem to agree on eliminating
798 the <Container ~ foo> forms, and using only
799 <ContainerMatch foo> semantics.
801 * SIGSEGV on Linux (glibc 2.1.2) isn't caught properly by a
802 sigwaiting thread. We need to work around this, perhaps unless
803 there is hope soon for a fixed glibc.
805 * orig_ct in the byterange/multipart handling may not be
806 needed. Apache 1.3 just never stashed "multipart" into
807 r->content_type. We should probably follow suit since the
808 byterange stuff doesn't want the rest of the code to see the
809 multipart content-type; the other code should still think it is
810 dealing with the <orig_ct> stuff.
811 Status: Greg volunteers to investigate (esp. since he was most
812 likely the one to break it :-)
814 Other features that need writing:
816 * Finish infrastructure in core for async MPMs
819 * TODO in source -- just do an egrep on "TODO" and see what's there
823 * Jon Travis's <jtravis@covalent.net> patch to deal with thread-safe
824 issues with inet_ntoa. See message <20001201163220.A12827@covalent.net>
825 Status: This is being set aside until the IPv6 work is finished
826 so that we know exactly what is required.
828 * Martin Sojka <msojka@gmx.de>'s patch to add error reporting for failed
829 htpasswd actions due to a full /tmp volume (other programs may have
834 * Mike Abbott's <mja@trudge.engr.sgi.com> patches to improve
836 Status: These were written for 1.3, and are awaiting a port to
839 * Jim Winstead's <jimw@trainedmonkey.com> patch to add CookieDomain and
840 other small mod_usertrack features
842 * Dan Rench's <drench@xnet.com> patch to add allow the errmsg and timefmt
843 of SSI's to be modified in the config file. Patch is available in
848 * Which MPMs will be included with Apache 2.0?
