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

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