1 Changes with Apache 2.0.18-dev
3 *) Limit the threaded mpm to quiescing one process at a time.
4 This is to fix a problem where the scoreboard is filled with
5 quiescing processes and no working processes can start.
8 *) Change how input filters decide how much data is returned to the
9 higher filter. We used to use a field in the conn_rec, with this
10 change, we use an argument to ap_get_brigade to determine how much
11 data is retrieved. [Ryan Bloom]
13 *) Fix seg fault at start-up introduced by Ryan's change to enable
14 modules to specify their own logging tags. mod_log_config
15 registers an optional function, ap_register_log_handler().
16 ap_register_log_handler() was being called by http_core before
17 the directive hash table was created. This patch creates the
18 directive hash table before ap_register_log_handler() is
19 registered as an optional function.
20 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
22 *) Add ap_set_int_slot() function
23 [John K. Sterling <sterling@covalent.net>]
25 *) Under certain circumstances, Apache did not supply the
26 right response headers when requiring authentication.
27 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
28 (This is a port of the change that went into Apache 1.3.19.)
30 *) Allow modules to specify their own logging tags. This basically
31 allows a module to tell mod_log_config that when %x is encountered
32 a specific function should be called. Currently, x can be any single
33 character. It may be more useful to make this a string at some point.
36 Changes with Apache 2.0.17
38 *) If a higher-level filter handles the the byterange aspects of a
39 request, then the byterange filter should not try to redo the
40 work. The most common case of this happening, is a byterange
41 request going through the proxy, and the origin server handles
42 the byterange request. The proxy should ignore it.
43 [Graham Leggett <minfrin@sharp.fm>]
45 *) Changed the threaded mpm to have child_main join to each of the
46 worker threads to make sure the kids are all gone before child_main
47 exits after a signal (cleanup from perform_idle_server_maintenance).
48 This is an extension of Ryans recent commit to make the child_main
51 *) Add more options to the ap_mpm_query function. This also allows MPMs to
52 report if their threads are dynamic or static. Finally, this also
53 implements a new API, ap_show_mpm, which returns the MPM that was
54 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
56 *) Do not install the binaries from the support directory twice.
57 [jun-ichiro hagino <itojun@iijlab.net>]
59 *) The ap_f* functions should flush data to the filter that is passed
60 in, not the the filter after the one passed in.
61 [Ryan Morgan <rmorgan@covalent.net>]
63 *) Make ab work again by changing its native types to apr types and formats.
64 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
66 *) Move the byterange filter and all of the supporting functions back
67 to the HTTP module. The byterange filter turned out to be very
68 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
70 *) Make clean, distclean, and extraclean consistently according to the
71 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
73 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
74 This may have been causing problems stopping processes in the threaded
77 *) Fix content-length in mod_negotiation to a long int representation.
80 *) Remove BindAddress from the default config file.
81 [giles@nemeton.com.au]
83 *) Allow module authors to add a module to their Apache build using
84 --with-module, without re-running buildconf. The syntax is:
85 --with-module=module_type:/path/to/module.c
86 The configure script will copy the module.c file to
87 modules/module_type, and it will be added to the relevant Makefiles.
88 currently, this only works for static modules. [Ryan Bloom]
90 *) Changes required to make prefork clean up idle children properly.
91 There was a window during which a starting worker deadlocks when
92 an idle cleanup arrives before it completes init. Apache then keeps
93 trying to cleanup the same deadlocked worker forever (until higher
94 pids come along, but it still will never reduce below the deadlocked
95 pid). Thus the number of children would not reduce to the correct
96 idle level. [Paul J. Reder]
98 Changes with Apache 2.0.16
100 *) Change the default installation directory to /usr/local/apache2,
101 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
103 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
106 *) Get MaxRequestsPerChild working with the Windows MPM.
109 *) Make generic hooks to work, with mod_generic_hook_import/export
110 experimental modules. [Ben Laurie, Will Rowe]
112 *) Fix segfaults for configuration file syntax errors such as
113 "<Directory>" followed by "</Directory" and
114 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
116 *) Cleanup the --enable-layout option of configure. This makes
117 us use a consistent location for the config.layout file, and it
118 makes configure more portable.
119 [jun-ichiro hagino <itojun@iijlab.net>]
121 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
122 csv/gnuplot format, rudimentary ssl support and various other tweaks
123 to make results more true to what is measured. The upshot of this it
124 turns out that 'ab' has often underreported the true performance of
125 apache. Often by a order of magnitude :-) See talk/paper of Sander
126 Temme <sctemme@covalent.net> at April ApacheCon 2001 for details.
127 [Dirk-Willem van Gulik]
129 *) Clean up mod_cgid's temporary request pool. Besides fixing a
130 storage leak this ensures that some unnecessary pipes are closed.
133 *) Performance: Add quick_handler hook. This hook is called at the
134 very beginning of the request processing before location_walk,
135 translate_name, etc. This hook is useful for URI keyed content
136 caches like Mike Abbott's Quick Shortcut Cache.
139 *) top_module global variable renamed to ap_top_module [Perl]
141 *) Move ap_set_last_modified to the core. This is a potentially
142 controversial change, because this is kind of HTTP specific. However
143 many protocols should be able to take advantage of this kind of
144 information. I expect that headers will need one more layer of
145 indirection for multi-protocol work, but this is a small step in
146 the right direction. [Ryan Bloom]
148 *) Enable mod_status by default. This matches what Apache 1.3 does.
151 *) Add a ScriptSock directive to the default config file. This is
152 only enabled when mod_cgid is used.
153 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
155 Changes with Apache 2.0.15
157 *) Untangled the buildconf script and eliminated the need for build's
158 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
159 libtool muck that is now under srclib/apr/build. [Roy Fielding]
161 *) Win32: Don't accept more connections than we have worker threads
165 *) Fix bug in the Unix threaded.c MPM that allowed child processes
166 to fork() new child processes.
169 *) Fix a major security problem with double-reverse lookup checking.
170 Previously, a client connecting over IPv4 would not be matched
171 properly when the server had an IPv6 listening socket. PR #7407
172 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
174 *) Change the way the beos MPM handles polling to allow it to stop and
175 restart. Problem was the sockets being polled were being reset by
176 the select call, so once it had accepted a connection it was no
177 longer listening on the UDP socket we use for shutdown instructions.
178 APR needs to be altered, patch on it's way. [David Reid]
180 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
181 on error exit from ap_getline(). Some other code got upset because
182 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
184 *) Handle ap_discard_request_body() being called more than once.
185 [Greg Ames, Jeff Trawick]
187 *) Get rid of an inadvertent close of file descriptor 2 in
188 mod_mime_magic. [Greg Ames, Jeff Trawick]
190 *) Add a hook, create_request. This hook allows modules to modify
191 a request while it is being created. This hook is called for all
192 request_rec's, main request, sub request, and internal redirect.
193 When this hook is called, the the r->main, r->prev, r->next
194 pointers have been set, so modules can determine what kind of
195 request this is. [Ryan Bloom]
197 *) Cleanup the build process a bit more. The Apache configure
198 script no longer creates its own helper scripts, it just
200 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
202 *) Stop the forced downgrade of the connection to HTTP/1.0 for
203 proxy requests. [Graham Leggett]
205 *) Avoid using sscanf to determine the HTTP protocol number in
206 the common case because sscanf is a performance hog. From
207 Mike Abbot's Accelerating Apache patch number 6.
208 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
210 *) Fix a security exposure in mod_access. Previously when IPv6
211 listening sockets were used, allow/deny-from-IPv4-address rules
212 were not evaluated properly (PR #7407). Also, add the ability to
213 specify IPv6 address strings with optional prefix length on Allow
214 and Deny. [Jeff Trawick]
216 *) Enhance rotatelogs so that a UTC offset can be specified, and
217 the logfile name can be formatted using strftime(3). (Brought
218 forward from 1.3.) [Ken Coar]
220 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
221 DuplicateHandle on an IOCompletionPort (a practice which
222 MS "discourages"). The new model does not rely on associating
223 the completion port with the listening sockets, thus the
224 completion port can be completely managed within the child
225 process. A dedicated thread accepts connections off the network,
226 then calls PostQueuedCompletionStatus() to wake up worker
227 threads blocked on the completion port.
230 *) Bring forward the --suexec-umask option which allows the
231 builder to preset the umask for suexec processes. [Ken Coar]
233 *) Add a -V flag to suexec, which causes it to display the
234 compile-time settings with which it was built. (Only
235 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
237 *) Mod_include should always unset the content-length if the file is
238 going to be passed through send_parsed_content. There is no to
239 determine if the content will change before actually scanning the
240 entire content. It is far safer to just remove the C-L as long
241 as we are scanning it. [Ryan Bloom]
243 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
244 request and not Proxy-Authenticate.
245 [Graham Leggett <minfrin@sharp.fm>]
247 Changes with Apache 2.0.14
249 *) Fix content-length computation. We ONLY compute a content-length if
250 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
251 or we already have all the data. [Ryan Bloom]
253 *) Report unbounded containers in the config file. Previously, a typo
254 in the </container> directive could result in the rest of the config
255 file being silently ignored, with undesired defaults used.
258 *) Make the old_write filter use the ap_f* functions for the buffering.
261 *) Move more code from the http module into the core server. This
262 is core code, basically the default handler, the default input
263 and output filters, and all of the core configuration directives.
264 All of this code is required in order for the server to work, with or
265 without HTTP. The server is closer to working without the HTTP
266 module, although there is still more to do. [Ryan Bloom]
268 *) Fix a number of SGI compile warnings throughout the server. Fix some
269 bad parameters to apr_bucket_read(). Fix a bad statement in
270 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
271 consistently; we were mixing apr_time_t and time_t in invalid ways
272 before. In load_file(), call apr_dso_error() instead of
273 apr_strerror() so that we get a more specific string on some platforms.
274 PR #6980 [Jeff Trawick]
276 *) Allow modules to query the MPM about it's execution profile. This
277 query API can and should be extended in the future, but for now,
278 max_daemons, and threading or forking is a very good start.
279 [Jon Travis <jtravis@covalent.net>]
281 *) Modify mod_include to send blocks of data no larger than 9k.
282 Without this, mod_include will wait until the whole file is parsed,
283 or the first tag is found to send any data to the client.
284 [Paul J. Reder <rederpj@raleigh.ibm.com>]
286 *) Fix mod_info, so that <Directory> and <Location> directives are
287 not displayed twice when displaying the current configuration.
288 [Ryan Morgan <rmorgan@covalent.net>]
290 *) Add config directives to override DEFAULT_ERROR_MSG and
291 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
292 [Dan Rench <drench@xnet.com>]
294 *) Get mod_info building and loading on Win32. [William Rowe]
296 *) Begin to move protocol independant functions out of mod_http. The goal
297 is to have only functions that are HTTP specific in the http directory.
300 Changes with Apache 2.0.13
302 *) Don't assume that there will always be multiple calls to the byterange
303 filter. It is possible that we will need to do byteranges with only
304 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
306 *) Move the error_bucket definition from the http module to the
307 core server. Every protocol will need this ability, not just
310 Changes with Apache 2.0.12
312 *) Modify mod_file_cache to save pre-formatted strings for
313 content-length and last-modified headers for performance.
314 [Mike Abbot <mja@trudge.engr.sgi.com>]
316 *) Namespace protect IOBUFSIZ since it is exposed in the API.
317 [Jon Travis <jtravis@covalent.net>]
319 *) Use "Basic" authentication instead of "basic" in ab, as the spec
320 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
322 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
323 without ever filling it out. This fixes PR 7271.
324 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
325 Cliff Woolley <cliffwoolley@yahoo.com>]
327 *) Add a couple of GCC attribute tags to printf style functions.
328 [Jon Travis <jtravis@covalent.net>]
330 *) Add the correct language tag for interoperation with the Taiwanese
331 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
333 *) Migrate the perchild MPM to use the new apr signal child, and
334 APR thread functions. [Ryan Bloom]
336 *) Close one copy of the CGI's stdout before creating the new process.
337 The CGI will still have stdout, because we have already dup'ed it.
338 This keeps Apache from waiting forever to send the results of a CGI
339 process that has forked a long-lived child process.
340 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
342 *) Remove the rest of the pthreads functions from the threaded MPM.
343 This requires the APR support for a signal thread that was just
346 *) Make mod_dir use a fixup for sending a redirect to the browser.
347 Before this, we were using a handler, which doesn't make much
348 sense, because the handler wasn't generating any data, it would
349 either return a redirect error code, or DECLINED. This fits the
350 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
352 *) Make the threaded MPM use APR threads instead of pthreads.
355 *) Get mod_tls to the point where it actually appears to work in all cases.
358 *) implement --enable-modules and --enable-mods-shared for "all" and
361 *) Move the threaded MPM to use APR locks instead of pthread locks.
364 *) Rename mpmt_pthread to threaded. This is more in line with the
365 fact that mpmt_pthread shouldn't be using pthreads directly, and
366 it is a smaller name that doesn't tie into anything.
369 *) Rename the module structures so that the exported symbol matches
370 the file name, and it is easier to automate the installation
371 process (generating LoadModule directives from the module filenames).
374 *) Remove the coalesce filter. With the ap_f* functions, this filter
375 is no longer needed. [Ryan Bloom]
377 Changes with Apache 2.0.11
379 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
380 added feature of allowing a uid/gid per child process. If no
381 uid/gid is specified, then Perchild behaves exactly like dexter.
384 *) Get perchild building again. [Ryan Bloom]
386 *) Don't disable threads just because we are using the prefork MPM.
387 If somebody wants to compile without threads, they must now add
388 --disable-threads to the configure command line. [Ryan Bloom]
390 *) Begin to move the calls to update_child_status into common code, so
391 that each individual MPM does not need to update the scoreboard itself.
394 *) Allow mod_tls to compile under Unix boxes where openssl has been
395 installed to the system include files.
396 [Gomez Henri <new-httpd@slib.fr>]
398 *) Cleanup the mod_tls configure process. This should remove any need
399 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
400 configure doesn't check that yet. [Ryan Bloom]
402 *) Add a very early prototype of SSL support (in mod_tls.c). It is
403 vital that you read modules/tls/README before attempting to build
406 *) Fix a potential seg fault on all platforms. David Reid fixed this
407 on BEOS, but the problem could happen anywhere, so we don't want
408 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
410 *) Add new LogFormat directive, %D, to log time it takes to serve a
411 request in microseconds. [Bill Stoddard]
413 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
414 SetOutputFilter. This corresponds nicely with the other Set
415 directives, which operate on containers while the Add* directives
416 tend to work directly on extensions. [Ryan Bloom]
418 *) Cleanup the header handling a bit. This uses the apr_brigade_*
419 functions for the buffering so that we don't need to compute
420 the length of the headers before we actually create the header
423 *) Allow filters to buffer data using the ap_f* functions. These have
424 become macros that resolve directly to apr_brigade_*.
427 *) Get the Unix MPM's to do a graceful restart again. If we are going
428 to register a cleanup with ap_cleanup_scoreboard, then we have to
429 kill the cleanup with the same function, and that function can't be
432 *) Install all required header files. Without these, it was not
433 possible to compile some modules outside of the server.
436 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
437 forward from 1.3 to 2.0, we missed a single line, which broke regex
438 aliases. [Ryan Bloom]
440 *) We have a poor abstraction in the protocol. This is a temporary
441 hack to fix the bug, but it will need to be fixed for real. If
442 we find an error while sending out a custom error response, we back
443 up to the first non-OK request and send the data. Then, when we send
444 the EOS from finalize_request_protocol, we go to the last request,
445 to ensure that we aren't sending an EOS to a request that has already
446 received one. Because the data is sent on a different request than
447 the EOS, the error text never gets sent down the filter stack. This
448 fixes the problem by finding the last request, and sending the data
449 with that request. [Ryan Bloom]
451 *) Make the server status page show the correct restart time, and
452 thus the proper uptime. [Ryan Bloom]
454 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
455 should reduce the amount of duplicate code that is required to
456 create CGI processes.
457 [Paul J. Reder <rederpj@raleigh.ibm.com>]
459 *) ap_new_connection() closes the socket and returns NULL if a socket
460 call fails. Usually this is due to a connection which has been
461 reset. [Jeff Trawick]
463 *) Move the Apache version information out of httpd.h and into release.h.
464 This is in preparation for the first tag with the new tag and release
467 *) Begin restructuring scoreboard code to enable adding back in
468 the ability to use IPC other than shared memory.
469 Get mod_status working on Windows again. [Bill Stoddard]
471 *) Make mod_status work with 2.0. This will work for prefork,
472 mpmt_pthread, and dexter. [Ryan Bloom]
474 *) Correct a typo in httpd.conf.
475 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
477 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
479 *) Get the correct IP address if ServerName isn't set and we can't
480 find a fully-qualified domain name at startup.
481 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
483 *) Make mod_cgid work with SuExec. [Ryan Bloom]
485 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
486 'extra' stat's for user/group since they should never occur, and now
487 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
488 volumes. [William Rowe]
490 *) Adopt apr features to simplify mod_includes. This changes the
491 behavior of the USER_NAME variable, unknown uid's are now reported
492 as USER_NAME="<unknown>" rather than the old user#000 result.
493 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
495 *) Adopt apr features for simplifing mod_userdir, and accept the new
496 Win32/OS2 exceptions without hiccuping. [William Rowe]
498 *) Replace configure --with-optim option by using and saving the
499 environment variable OPTIM instead. This is needed because configure
500 options do not support multiple flags separated by spaces.
503 *) Fix some byterange handling. If we get a byte range that looks like
504 "-999999" where that is past the end of the file, we should return
505 a PARTIAL CONTENT status code, and return the whole file as one big
506 byterange. This matches the 1.3 handling now. [Ryan Bloom]
508 *) Make the error bucket a real meta-data bucket. This means that the
509 bucket length is 0, and a read returns NULL data. If one of these
510 buckets is passed down after the headers are sent, this data will
511 just be ignored. [Greg Stein]
513 *) The prefork MPM wasn't killing child processes correctly if a restart
514 signal was received while the process was serving a request. The child
515 process would become the equivalent of a second parent process. If
516 we break out of the accept loop, then we need to do die after cleaning
517 up after ourselves. [Ryan Bloom]
519 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
520 restarts. [Ryan Bloom]
522 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
523 the most optimal APR_FINFO_wanted bits. This spares Win32 from
524 performing very expensive owner, group and permission lookups
525 and allows the server to function until these apr_finfo_t fields
526 are implemented under Win32. [William Rowe]
528 *) Support for typedsafe optional functions - that is functions exported by
529 optional modules, which, therefore, may or may not be present, depending
530 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
531 for sample code. [Ben Laurie]
533 *) filters can now report an HTTP error to the server. This is done
534 by sending a brigade where the first bucket is an error_bucket.
535 This bucket is a simple bucket that stores an HTTP error and
536 a string. Currently the string is not used, but it may be needed
537 to output an error log. The http_header_filter will find this
538 bucket, and output the error text, and then return
539 AP_FILTER_ERROR, which informs the server that the error web page
540 has already been sent. [Ryan Bloom]
542 *) If we get an error, then we should remove all filters except for
543 those critical to serving a web page. This fixes a bug, where
544 error pages were going through the byterange filter, even though
545 that made no sense. [Ryan Bloom]
547 *) Relax the syntax checking of Host: headers in order to support
548 iDNS. PR#6635 [Tony Finch]
550 *) Cleanup the byterange filter to use the apr_brigade_partition
551 and apr_bucket_copy functions. This removes a lot of very messy
552 code, and hopefully makes this filter more stable.
555 *) Remove AddModule and ClearModuleList directives. Both of these
556 directives were used to ensure that modules could be enabled
557 in the correct order. That requirement is now gone, because
558 we use hooks to ensure that modules are in the correct order.
561 *) When SuExec is specified, we need to add it to the list of
562 targets to be built. If we don't, then any changes to the
563 configuration won't affect SuExec, unless 'make suexec' is
564 specifically run. [Ryan Bloom]
566 *) Cleaned out open_file from mod_file_cache, as apr now accepts
567 the APR_XTHREAD argument to open a file for consumption by
568 parallel threads on win32. [William Rowe]
570 *) Correct a bug in determining when we follow symlinks. The code
571 expected a stat -1 result, not an apr_status_t positive error.
572 Also check if the APR_FINFO_USER fields are valid before we
573 follow the link. [William Rowe]
575 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
576 mpm_common.c. These functions are only valid on some platforms,
577 so they should not be in the main-line code. [Ryan Bloom]
579 *) Remove ap_chdir_file(). This function is not thread-safe,
580 and nobody is currently using it. [Ryan Bloom]
582 *) Do not try to run make depend if there are no .c files in the
583 current directory, doing so makes `make depend` fail.
586 *) Update highperformance.conf to work with either prefork or
587 pthreads mpms. [Greg Ames]
589 *) Stop checking to see if this is a pipelined request if we know
590 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
591 This keeps us from making an extra read call when serving a 1.0
592 request. [Ryan Bloom and Greg Stein]
594 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
595 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
596 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
598 *) Fix the RFC number mentioned when complaining about a missing
599 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
601 *) Fix an endless loop in ab which occurred when ab was posting
602 and the server dropped the connection unexpectedly.
605 *) Fix a segfault while handling request bodies in ap_http_filter().
606 This problem has been seen with mod_dav usage as well as with
607 requests where the body was just being discarded. [Jeff Trawick]
609 *) Some adjustment on the handling and automatic setting (via
610 hints.m4) of various compilation flags (eg: CFLAGS). Also,
611 add the capability to specify flags (NOTEST_CFLAGS and
612 NOTEST_LDFLAGS) which are used to compile Apache, but
613 not used during the configuration process. Useful for
614 flags like "-Werror". [Jim Jagielski]
616 *) Stop using environment variables to force debug mode or
617 no detach. We now use the -D command line argument to
618 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
619 [Greg Stein, Ryan Bloom]
621 *) Change handlers to use hooks. [Ben Laurie]
623 *) Stop returning copies of filenames from both apr_file_t and
624 apr_dir_t. We pstrdup the filenames that we store in the
625 actual structures, so we don't need to pstrdup the strings again.
628 *) mod_cgi: Fix some problems where the wrong error value was being
629 traced. [Jeff Trawick]
631 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
634 *) Add generic hooks. [Ben Laurie]
636 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
638 *) Fix a segfault caused by mod_ext_filter when the external filter
639 program does not exist. [Jeff Trawick]
641 *) Fix an output truncation error when on an HTTP >= 1.0 request an
642 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
643 was served through mod_charset_lite (or anything else that would
644 create a transient bucket in this size range). ap_bucket_make_heap()
645 silently failed (fixed), transient_setaside() discovered it, but
646 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
648 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
649 is that some browsers send extra lines at the end of POST requests, and
650 we don't want to delay sending data back to the user just because the
651 browser isn't well behaved. [Ryan Bloom]
653 *) Get SuEXEC working again. We can't send absolute paths to suExec
654 because it refuses to execute those programs. SuEXEC also wasn't
655 always recognizing configuration changes made using the autoconf
658 *) Allow the buildconf process to find the config.m4 files in the correct
659 order. Basically, we can now name config.m4 files as config\d\d.m4,
660 and we will sort them correctly when inserting them into the build
661 process. [Ryan Bloom]
663 *) Get mod_cgid to use apr calls for creating the actual CGI process.
664 This also allows mod_cgid to use ap_os_create_priviledged_process,
665 thus allowing for SuExec execution from mod_cgid. Currently, we do
666 not support everything that standard SuExec supports, but at least
667 it works minimally now. [Ryan Bloom]
669 *) Allow SuExec to be configured from the ./configure command line.
672 *) Update some of the docs in README and INSTALL to reflect some of
673 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
675 *) If we get EAGAIN returned from the call to apr_sendfile, then we
676 need to call sendfile again. This gets us serving large files
677 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
679 *) Get the support programs building cleanly again.
680 [Cliff Woolley <cliffwoolley@yahoo.com>]
682 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
683 current directory logic now backs up over bin/ to determine the
684 server root from the Apache.exe path.
686 *) Apache/Win32 now follows the standard conventions of mod_foo.so
687 loadable modules, dynamic libs are all named libfoo.dll, and the
688 makefile.win populates the include, lib and libexec directories.
690 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
691 Apache gets IPv6 listening sockets by default. Additionally, the
692 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
693 numeric address strings (e.g., "Listen [fe80::1]:8080").
696 *) Modify the install directory layout. Modules are now installed in
697 modules/. Shared libraries should be installed in libraries/, but
698 we don't have any of those on Unix yet. All install directories
699 are modifyable at configure time. [Ryan Bloom]
701 *) Install all header files in the same directory on Unix. [Ryan Bloom]
703 *) Get the functions in server/linked into the server, regardless of
704 which modules linked into the server. This uses the same hack
705 for Apache that we use for APR and apr-util to ensure all of the
706 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
707 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
708 the scripts a bit easier.
711 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
712 on the query, and remove IPv4 dependencies. [Jeff Trawick]
714 *) Get all of the auth modules to the point that they will install and
715 be loadable into the server. Our new build/install mechanism expects
716 that all modules will have a common name format. The auth modules
717 didn't use that format, so we didn't install them properly.
720 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
721 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
723 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
725 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
726 after the end of the response. [Ryan Bloom]
728 *) Get byterange requests working with responses that do not have a
729 content-length. Because of the way byterange requests work, we have to
730 have all of the data before we can actually do the byterange, so we
731 can compute the content-length in the byterange filter.
734 *) Get exe CGI's working again on Windows.
737 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
738 they keep track of whether or not their post config hook has been
739 called before. Instead of a static variable (which is replaced when
740 the DSO is loaded a second time), use userdata in the process pool.
743 Changes with Apache 2.0a9
745 *) Win32 now requires perl to complete the final install step for users
746 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
747 and installs the conf, htdocs and htdocs/manual directories.
750 *) Make mod_include use a hash table to associate directive tags with
751 functions. This allows modules to implement their own SSI tags easily.
752 The idea is simple enough, a module can insert it's own tag and function
753 combination into a hash table provided by mod_include. While mod_include
754 parses an SSI file, when it encounters a tag in the file, it does a
755 hash lookup to find the function that implements that tag, and passes
756 all of the relevant data to the function. That function is then
757 responsible for processing the tag and handing the remaining data back
758 to mod_include for further processing.
759 [Paul J. Reder <rederpj@raleigh.ibm.com>]
761 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
762 fewer parameters: the local and remote socket addresses were removed
763 from the parameter list because all required information is available
764 via the APR socket. [Jeff Trawick]
766 *) Distribution directory structure reorganized to reflect a
767 normal source distribution with external install targets.
770 *) The MPMs that need multiple segments of shared memory now create
771 two apr_shmem_t variables, one for each shared memory allocation.
772 the problem is that we can't determine how much memory will be required
773 for shared memory allocations once we try to allocate more than one
774 variable. The MM code automatically aligns the shared memory allocations,
775 so we end up needing to pad the amount of shared memory we want based
776 on how many variables will be allocated out of the shared memory segment.
777 It is just easier to create a second apr_shmem_t variable, and two
781 *) Cleanup the export list a bit. This creates a single unified list of
782 functions exported by APR. The export list is generated at configure
783 time, and that list is then used to generate the exports.c file.
784 Because of the way the export list is generated, we only export those
785 functions that are valid on the platform we are building on.
788 *) Enable logging the cookie with mod_log_config
789 [Sander van Zoest <sander@covalent.net>]
791 *) Fix a segfault in mod_info when it reaches the end of the configuration.
794 *) Added lib/aputil/ as a placeholder for utility functions which are not
795 specific to the Apache HTTP Server (but do not make sense with APR).
796 The first utility is "apu_dbm": a set of functions to work with DBM
797 files. This first version can be compiled for SDBM or GDBM databases.
800 *) Complete re-write of mod_include. This makes mod_include a filter that
801 uses buckets directly. This has now served the FAQ correctly.
802 [Paul Reder <rederpj@raleigh.ibm.com>]
804 *) Allow modules to specify the first filter in a sub_request when
805 making the sub_request. This keeps modules from having to change the
806 output_filter immediately after creating the sub-request, and therefore
807 skip the sub_req_output_filter. [Ryan Bloom]
809 *) Update ab to accept URLs with IPv6 literal address strings (in the
810 format described in RFC 2732), and to build Host header fields in
811 the same format. This allows IPv6 literal address strings to be
812 used with ab. This support has been tested against Apache 1.3 with
813 the KAME patch, but Apache 2.0 does not yet work with this format
814 of the Host header field. [Jeff Trawick]
816 *) Accomodate an out-of-space condition in the piped logs and the
817 rotatelogs.c code, and no longer churn log processes for this
818 condition. [Victor J. Orlikowski]
820 *) Add support for partial writes with apr_sendfile() to core_output_filter.
823 Changes with Apache 2.0a8
825 *) Add a directive to mod_mime so that filters can be associated with
829 *) Get multi-views working again. We were setting the path_info
830 field incorrectly if we couldn't find the specified file.
833 *) Fix 304 processing. The core should never try to send the headers
834 down the filter stack. Always, just setup the table in the request
835 record, and let the header filter convert it to data that is ready
839 *) More fixes for the proxy. There are still bugs in the proxy code,
840 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
844 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
847 *) APR: Add new apr_getopt_long function to handle long options.
848 [B. W. Fitzpatrick <fitz@red-bean.com>]
850 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
851 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
852 hostname resolution/address string parsing and building
853 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
854 of one of the apr_sockaddr_t structures for a socket. Change
855 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
857 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
858 I have proxied pages with it, cleanup will commence soon.
861 *) Make the proxy work with filters. This isn't perfect, because we
862 aren't dealing with the headers properly. [Ryan Bloom]
864 *) Do not send a content-length iff the C-L is 0 and this is a head
865 request. [Ryan Bloom]
867 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
868 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
870 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
872 *) Get the default_handler to stop trying to deal with HEAD requests.
873 The idea is to let the content-length filter compute the C-L before
874 we try to send the data. If we can get the C-L correctly, then we
875 should send it in the HEAD response.
878 *) The Header filter can now determine if a body should be sent based
879 on r->header_only. The general idea of this is that if we delay
880 deciding to send the body, then we might be able to compute the
881 content-length correctly, which will help caching proxies to cache
882 our data better. Any handler that doesn't want to try to compute
883 the content-length can just send an EOS bucket without data and
884 everything will just work.
887 *) Add the referer to the error log if one is available.
888 [Markus Gyger <mgyger@itr.ch>]
890 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
891 change, the root of the configuration tree has been exposed to modules
893 [Ryan Morgan <rmorgan@covalent.net>]
895 *) Get the core_output_filter to use the bucket interface directly.
896 This keeps us from calling the content-length filter multiple times
897 for a simple static request.
900 *) We are sending the content-type correctly now.
901 [Ryan Bloom and Will Rowe]
903 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
904 a bogus bytes-sent value when the only thing being sent was trailers
905 and writev() returned an error (or EAGAIN). [Jeff Trawick]
907 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
908 hints file to determine which platforms define
909 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
912 *) APR: add apr_get_home_directory() [Jeff Trawick]
914 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
916 *) Not all platforms have INADDR_NONE defined by default. Apache
917 used to make this check and define INADDR_NONE if appropriate,
918 but APR needs the check too, and I suspect other applications will
919 as well. APR now defines APR_INADDR_NONE, which is always a valid
920 value on all platforms.
921 [Branko Èibej <brane@xbc.nu>]
923 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
924 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
926 *) Relax the syntax checking of Host: headers in order to support
927 iDNS. PR#6635 [Tony Finch]
929 *) When reading from file buckets we convert to an MMAP if it makes
930 sense. This also simplifies the default handler because the
931 default handler no longer needs to try to create MMAPs.
934 *) BUFF has been removed from the main server. The BUFF code will remain
935 in the code until it has been purged from the proxy module as well.
938 *) Byteranges have been completely re-written to be a filter. This
939 has been tested, and I believe it is working correctly, but it could
940 doesn't work for the Adobe Acrobat plug-in. The output almost matches
941 the output from 1.3, the only difference being that 1.3 includes
942 a content-length in the response, and this does not.
945 *) APR read/write functions and bucket read functions now operate
946 on unsigned integers, instead of signed ones. It doesn't make
947 any sense to use signed ints, because we return the error codes,
948 so if we have an error we should report 0 bytes read or written.
951 *) Always compute the content length, whether it is sent or not.
952 The reason for this, is that it allows us to correctly report
953 the bytes_sent when logging the request. This also simplifies
954 content-length filter a bit, and fixes the actual byte-reporing
955 code in mod_log_config.c
958 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
959 it says, because it was only used by EOS and FLUSH buckets. Since
960 neither of those are required at the end of a brigade, this was
961 really signifying FLUSH_THE_DATA, but that can be determined better
962 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
963 buckets now return a length of 0, which is actually the amount of data
964 read, so they make more sense.
967 *) Allow the core_output_filter to save some data past the end of a
968 request. If we get an EOS bucket, we only send the data if it
969 makes sense to send it. This allows us to pipeline request
970 responses. As a part of this, we also need to allocate mmap
971 buckets out of the connection pool, not the request pool. This
972 allows the mmap to outlive the request.
975 *) Make blocking and non-blocking bucket reads work correctly for
976 sockets and pipes. These are the only bucket types that should
977 have non-blocking reads, because the other bucket types should
978 ALWAYS be able to return something immediately.
981 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
982 server, but use Ctrl+Break to initiate a graceful restart
983 instead of duplicating behavior. [John Sterling]
985 *) Patch mod_autoindex to set the Last-Modified header based on
986 the directory's mtime, and add the ETag header. [William Rowe]
988 *) Merge the 1.3 patch to add support for logging query string in
989 such a way that "%m %U%q %H" is the same as "%r".
992 *) Port three log methods from mod_log_config 1.3 to 2.0:
993 CLF compliant '-' byte count, method and protocol.
996 *) Add a new LogFormat directive, %c, that will log connection
997 status at the end of the response as follows:
998 'X' - connection aborted before the response completed.
999 '+' - connection may be kept-alive by the server.
1000 '-' - connection will be closed by the server.
1003 *) Expand APR for WinNT to fully accept and return utf-8 encoded
1004 Unicode file names and paths for Win32, and tag the Content-Type
1005 from mod_autoindex to reflect that charset if the the feature
1006 macro APR_HAS_UNICODE_FS is true. [William Rowe]
1008 *) Compute the content length (and add appropriate header field) for
1009 the response when no content length is available and we can't use
1010 chunked encoding. [Jeff Trawick]
1012 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
1013 so that content input filters get dechunked data when using
1014 the default handler. Also removed REQUEST_CHUNKED_PASS.
1017 *) Add mod_ext_filter as an experimental module. This module allows
1018 the administrator to use external programs as filters. Currently,
1019 only filtering of output is supported. [Jeff Trawick]
1021 *) Most Apache functions work on EBCDIC machines again, as protocol
1022 data is now translated (again). [Jeff Trawick]
1024 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
1025 the EBCDIC support. They are noops on ASCII machines, so this
1026 type of translation doesn't have to be surrounded by #ifdef
1027 CHARSET_EBCDIC. [Jeff Trawick]
1029 *) Fix mod_include. tag commands work again, and the server will
1030 send the FAQ again. This also allows mod_include to set aside
1031 buckets that include partial buckets.
1032 [Ryan Bloom and David Reid]
1034 *) Add suexec support back. [Manoj Kasichainula]
1036 *) Lingering close now uses the socket directly instead of using
1037 BUFF. This has been tested, but since all we can tell is that it
1038 doesn't fail, this needs to be really hacked on.
1041 *) Allow filters to modify headers and have those headers be sent to
1042 the client. The idea is that we have an http_header filter that
1043 actually sends the headers to the network. This removes the need
1044 for the BUFF to send headers.
1047 *) Charset translation: mod_charset_lite handles translation of
1048 request bodies. Get rid of the xlate version of ap_md5_digest()
1049 since we don't compute digests of filtered (e.g., translated)
1050 response bodies this way anymore. (Note that we don't do it at
1051 all at the present; somebody needs to write a filter to do so.)
1054 *) Input filters and ap_get_brigade() now have a input mode parameter
1055 (blocking, non-blocking, peek) instead of a length parameter.
1058 *) Update the mime.types file to the registered media types as
1059 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
1062 *) Namespace protect some macros declared in ap_config.h
1065 *) Support HTTP header line folding with input filtering.
1068 *) Mod_include works again. This should still be re-written, but at
1069 least now we can serve an SHTML page again.
1072 *) Begin to remove BUFF from the core. Currently, we keep a pointer
1073 to both the BUFF and the socket in the conn_rec. Functions that
1074 want to use the BUFF can, functions that want to use the socket,
1075 can. They point to the same place.
1078 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
1079 [Tomas "Ögren" <stric@ing.umu.se>]
1081 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
1082 associated pool goes away. (APR pipes on OS/2 were already had this
1083 logic.) This resolvs a fatal file descriptor leak with CGIs.
1086 *) The final line of the config file was not being read if there was
1087 no \n at the end of it. This was caused by apr_fgets returning
1088 APR_EOF even though we had read valid data. This is solved by
1089 making cfg_getline check the buff that was returned from apr_fgets.
1090 If apr_fgets return APR_EOF, but there was data in the buf, then we
1091 return the buf, otherwise we return NULL.
1094 *) Piped logs work again in the 2.0 series.
1097 *) Restore functionality broken by the mod_rewrite security fix:
1098 rewrite map lookup keys and default values are now expanded
1099 so that the lookup can depend on the requested URI etc.
1100 PR #6671 [Tony Finch]
1102 *) Tighten up the syntax checking of Host: headers to fix a
1103 security bug in some mass virtual hosting configurations
1104 that can allow a remote attacker to retrieve some files
1105 on the system that should be inaccessible. [Tony Finch]
1107 *) Add a pool bucket type. This bucket is used for data allocated out
1108 of a pool. If the pool is cleaned before the bucket is destroyed, then
1109 the data is converted to a heap bucket, allowing it to survive the
1113 *) Add a flush bucket. This allows modules to signal that the filters
1114 should all flush whatever data they currently have. There is no way
1115 to actually force them to do this, so if a filter ignores this bucket,
1116 that's life, but at least we can try with this.
1119 *) Add an output filter for sub-requests. This filter just strips the
1120 EOS bucket so that we don't confuse the main request's core output
1121 filter by sending multiple EOS buckets. This change also makes sub
1122 requests start to send EOS buckets when they are finished.
1125 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
1126 makes ap_bucket_destroy a return void, which is okay because it
1127 used to always return APR_SUCCESS, and nobody ever checked its
1128 return value anyway.
1129 [Cliff Woolley <cliffwoolley@yahoo.com>]
1131 *) Remove the index into the bucket-type table from the buckets
1132 structure. This has now been replaced with a pointer to the
1133 bucket_type. Also add some macros to test the bucket-type.
1136 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
1137 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
1138 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
1139 All _VAR_ flavors changes to _DATA to be absolutely clear.
1142 *) Add support for /, //, //servername and //server/sharename
1143 parsing of <Directory> blocks under Win32 and OS2.
1144 [Tim Costello, William Rowe, Brian Harvard]
1146 *) Remove the function pointers from the ap_bucket type. They have been
1147 replaced with a global table. Modules are allowed to register bucket
1148 types and use then use those buckets.
1151 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
1152 once we finish writing the request body to the cgi child process;
1153 otherwise, the client doesn't hit EOF on stdin. Small request bodies
1154 worked without this change (for reasons I don't understand), but large
1155 ones didn't. [Jeff Trawick]
1157 *) Remove file bucket specific information from the ap_bucket type.
1158 This has been moved to a file_bucket specific type that hangs off
1159 the data pointer in the ap_bucket type.
1162 *) Input filtering now has a third argument. This is the amount of data
1163 to read from lower filters. This argument can be -1, 0, or a positive
1164 number. -1 means give me all the data you have, I'll deal with it and
1165 let you know if I need more. 0 means give me one line and one line
1166 only. A positive number means I want no more than this much data.
1168 Currently, only 0 and a positive number are implemented. This allows
1169 us to remove the remaining field from the conn_rec structure, which
1173 *) Big cleanup of the input filtering. The goal is that http_filter
1174 understands two conditions, headers and body. It knows where it is
1175 based on c->remaining. If c->remaining is 0, then we are in headers,
1176 and http_filter returns a line at a time. If it is not 0, then we are
1177 in body, and http_filter returns raw data, but only up to c->remaining
1178 bytes. It can return less, but never more.
1179 [Greg Ames, Ryan Bloom, Jeff Trawick]
1181 *) mod_cgi: Write all of the request body to the child, not just what
1182 the kernel would accept on the first write. [Jeff Trawick]
1184 *) Back out the change that moved the brigade from the core_output_filters
1185 ctx to the conn_rec. Since all requests over a given connection
1186 go through the same core_output_filter, the ctx pointer has the
1190 *) Fix another bug in the send_the_file() read/write loop. A partial
1191 send by apr_send would cause unsent data in the read buffer to
1192 get clobbered. Complete making send_the_file handle partial
1193 writes to the network.
1196 *) Fix a couple of type fixes to allow compilation on AIX again
1197 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
1199 *) Fix bug in send_the_file() which causes offset to be ignored
1200 if there are no headers to send.
1203 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
1204 filter. Useful for supporting Windows 9* with a binary
1205 compiled on Windows NT.
1208 Changes with Apache 2.0a7
1210 *) Reimplement core_output_filter to buffer/save bucket brigades
1211 across multiple calls to the core_filter. The brigade will be
1212 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
1213 thresholds are hit or the EOS bucket is received.
1216 *) Create experimental filter (buffer_filter) that coalesces bytes
1217 into one large buffer before invoking the next filter in the
1218 chain. This filter is particularly useful with the current
1219 implementation of mod_autoindex when it inserted above the
1220 chunk_filter. mod_autoindex generates a lot of brigades that
1221 containing buckets holding just a few bytes each. The
1222 buffer_filter coalesces these buckets into a single large bucket.
1225 *) Add apr_sendfile() support into the core_output_filter.
1228 *) Add apr_sendv() support into the core_output_filter.
1231 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
1232 [Mike Abbott <mja@sgi.com>]
1234 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
1235 make much sense, because Apache uses buckets instead of BUFFs now.
1238 *) send_the_file now falls back to a read/write loop on platforms that
1239 do not have sendfile.
1240 [Ryan Bloom and Brian Havard]
1242 *) Install apachectl correctly, and substitute the proper values so
1243 that it works again. [Ryan Bloom]
1245 *) Better(??) handle platforms that lack sendfile().
1248 *) APR now has UUID generation/formatting/parsing support.
1251 *) Begin the http_filter. This is an input filter that understands
1252 the absolute basic amount required to parse an HTTP Request. The
1253 goal is to be able to split headers from request body before passing
1254 the data back to the other filters.
1257 *) Bring forward from 1.3.13 the config directory implementation
1260 *) install apxs if it is created
1263 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
1264 conversions. [William Rowe]
1266 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
1267 ap_add_output_filter(). [Jeff Trawick]
1269 *) Multiple build and configuration fixes
1272 -add datadir and localstatedir substitutions
1274 -fix logfilename misspelling
1275 -fix evaluation of installation dir variables and
1276 -replace $foobar by $(foobar) to be usefull in the makefile
1280 -add rules for cross-compiling in rules.mk. Okay, rule to check for
1281 $CC_FOR_BUILD is still missing
1282 -use CHECK_TOOL instead of CHECK_PROG for ranlib
1283 -add missing "AR=@AR@" to severaly Makefile.in's
1284 -cache result for "struct rlimit"
1285 -compile all helper programs with native and cross compiler
1286 and use the native version to generate header file
1287 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
1289 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
1291 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
1293 *) Fix a bug where a client which only sends \n to delimit header
1294 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
1295 message. Start working on ebcdic co-existance with input
1297 [William Rowe, Greg Ames]
1299 *) If mod_so is enabled in the server always create libexec, even
1300 if there are no modules installed in this directory. This is a
1301 requirement for APXS to work correctly.
1304 *) Connection oriented output filters are now stored in the
1305 conn_rec instead of the request_rec. This allows us to add the
1306 output filter in the pre-connection phase instead of the
1307 post_read_request phase, which keeps us from trying to write an
1308 error page before we have a filter to write to the network.
1309 [Ryan Bloom, Jeff Trawick, and Greg Ames]
1311 *) Cleaning up an mmap bucket no longer deletes the mmap. An
1312 mmap can be used across multiple buckets (default_handler with
1313 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
1314 the mmap itself can't be associated with the bucket.
1317 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
1320 *) Radical surgery to improve mod_isapi support under Win32.
1321 Includes a number of newer ServerSupportFunction calls, support
1322 for ReadClient (in order to retrieve POSTs greater than 48KB),
1323 and general bug fixes to more reliably load ISAPI .dll's and
1324 prevent leaking handle resources. Note: There are still
1325 discrepancies between IIS's and Apache's ServerVariables, and
1326 async calls are still not supported. Additional warnings are
1327 logged to facilitate debugging of unsupported ISAPI calls.
1330 *) Add input filtering to Apache. The basic idea for the input
1331 filters is the same as the ideas for output filters. The biggest
1332 difference is that instead of calling ap_pass_brigade, ap_get_brigade
1333 should be called, and the order of execution for the filter itself is
1334 different. When writing an output filter, a brigade is passed in,
1335 and filters operate directly on that brigade, when done, they call
1336 ap_pass_brigade. Input filters are the exact opposite. Because input
1337 is not a push operation, filters first call ap_get_brigade. When this
1338 function returns, the input filter will be left with a valid brigade.
1339 The input filter should then operate on the brigade, and return.
1342 *) Fix building on BSD/OS using its native make. The build system
1343 falls back to the BSD .include directive on that host platform.
1346 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
1347 SHA1 and plaintext password encodings. Make feature tests a
1348 bit more flexible. [William Rowe]
1350 *) Charset translation: mod_charset_lite handles output content
1351 translation in a filter. mod_charset_lite no longer ignores
1352 subrequests. A bunch of cruft related to BUFF's support for
1353 translating request and response bodies was removed.
1356 *) Move the addition of the CORE filter to the post_read_request
1357 hook in http_core.c. This removes the need to add the filter in
1358 multiple places and allows for an SSL module to be added much
1359 simpler. [Ryan Bloom]
1361 *) Fix a security problem that affects certain configurations of
1362 mod_rewrite. If the result of a RewriteRule is a filename that
1363 contains expansion specifiers, especially regexp backreferences
1364 $0..$9 and %0..%9, then it may be possible for an attacker to
1365 access any file on the web server. [Tony Finch]
1367 *) Fix a bug where errors that are detected during early request parsing
1368 don't produce visible HTTP error messages at the browser, because
1369 the core_filter wasn't present. [Greg Ames]
1371 *) Provide apr_socklen_t as a portability aid.
1372 [Victor J. Orlikowski]
1374 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
1375 as well as a comment arg to the add, adduser and update cmds.
1376 update allows the user to clear or preserve pw/groups/comment.
1377 Fixed a bug in dbmmanage that prevented the check option from
1378 parsing a password followed by :group... text. Corrected the
1379 seed calcualation for Win32 systems, and added -lsdbm support.
1382 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
1385 *) Avoid a segfault when parsing .htaccess files. An
1386 uninitialized tree pointer was passed to ap_build_config().
1389 *) Change the way that inet_addr & inet_network are checked for
1390 in APR's configure process to allow BeOS BONE to correctly
1391 find them. With this change BeOS BONE now builds from source
1392 with no problems. [David Reid]
1394 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
1395 the end of the parameters to execve() was stored in the wrong
1396 location, overlaying the storage beyond the newargs[] array and
1397 also passing uninitialized storage to execve(), which would
1398 sometimes fail with EFAULT. [Jeff Trawick]
1400 *) Fix a bug parsing configuration file containers. With a sequence
1401 like this in the config file
1403 <IfModule mod_kilroy.c>
1406 <IfModule mod_lovejoy.c>
1411 the second container would be terminated at the blank line due to
1412 sediment in the buffer from reading the prior </IfModule> and an
1413 error message would be generated for the real </IfModule> for the
1414 second container. Also due to this problem, any two characters
1415 could be used for "</" in the close of a container.
1418 *) ap_add_filter prototype changed to remove the ctx pointer. The
1419 pointer still remains in the filter structure, but it can not be
1420 a part of the ap_add_filter prototype. The reason is that when
1421 the core uses AddFilter to add a filter to the stack it doesn't
1422 know how to allocate the ctx pointer, or even how much memory should
1423 be allocated. The filters will have to be responsible for allocating
1424 the ctx memory when they need it.
1427 *) Add an AddFilter directive. This directive takes a list of filters
1428 that should be activated for the requested resource.
1431 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
1432 some other platforms). [Jeff Trawick]
1434 *) Modify mod_include to be a filter. Currently, it has only been tested
1435 on actual files, but it should work for CGI scripts too.
1438 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
1439 writes. apr_flush() for Unix: handle interrupted writes.
1442 *) NameVirtualHost can now take "*" as an argument instead of
1443 an IP address. This allows you to create a purely name-based
1444 virtual hosting server that does not have any IP addresses in
1445 the configuration file and which ignores the local address
1446 of any connections. PR #5595, PR #4455 [Tony Finch]
1448 *) Fix some compile warnings in mod_mmap_static.c
1449 [Mike Abbott <mja@sgi.com>]
1451 *) Fix chunking problem with CGI scripts. The general problem was that
1452 the CGI modules were adding an EOS bucket and then the core added an
1453 EOS bucket. The chunking filter finalizes the chunked response when it
1454 encounters an EOS bucket. Because two EOS buckets were sent, we
1455 finalized the response twice. The fix is to make sure we only send one
1456 EOS, by utilizing a flag in the request_rec.
1459 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
1460 and Win32. Previously, the first read from an apr_file_t set up via
1461 apr_put_os_file() would return a '\0'. [Jeff Trawick]
1463 *) Mod_cgid now creates a single element bucket brigade, with a pipe
1464 bucket, instead of using BUFF's and ap_r*.
1467 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
1468 [Mike Abbott <mja@sgi.com>]
1470 *) Remove ap_bopenf from buff code. This required modifying the file_cache
1471 code to use APR file's directly instead of going through BUFFs.
1474 *) Fix compile break on some platforms for mod_mime_magic.c
1475 [John K. Sterling <sterling@covalent.net>]
1477 *) Fix merging of AddDefaultCharset directive.
1478 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
1480 *) Minor revamp of the rlimit sections of code. We now test
1481 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
1482 is now "available" even if the platform doesn't support
1483 the rlimit family (it's just a noop though). [Jim Jagielski]
1485 *) Migrate the pre-selection of which MPM to use for specific
1486 platforms to hints.m4, which contains (or should contain)
1487 all platform specific "hints". [Jim Jagielski]
1489 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
1492 *) Add tables with non-string/binary values to APR.
1495 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
1498 *) Update PCRE to version 3.2. [Ryan Bloom]
1500 *) Change the way buckets' destroy functions are called so that
1501 they can be more directly used when changing the type of a
1502 bucket in place. [Tony Finch]
1504 *) Add generic support for reference-counting the resources used by
1505 buckets, and alter the HEAP and MMAP buckets to use it. Change
1506 the way buckets are initialised to support changing the type of
1507 buckets in place, and use it when setting aside TRANSIENT buckets.
1508 Change the implementation of TRANSIENT buckets so that it can be
1509 mostly shared with IMMORTAL buckets, which are now implemented.
1512 Changes with Apache 2.0a6
1514 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
1516 *) Add a chunking filter to Apache. This brings us one step closer
1517 to removing BUFF. [Ryan Bloom]
1519 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
1520 added to the stack is the last filter to be called. [Ryan Bloom]
1522 *) Apache 2.0 has been completely documented using Scandoc. The
1523 docs can be generated by running 'make docs'. [Ryan Bloom]
1525 *) Add filtered I/O to Apache. This is based on bucket brigades,
1526 Currently the buckets still use BUFF under the covers, but that
1527 should change quickly. The only currently written filter is the
1528 core filter which just calls ap_bwrite. [The Apache Group]
1530 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
1531 built with thread support. [Jeff Trawick]
1533 *) Abort configuration if --with-layout was specified and there's
1534 no layout definition file. [Ken Coar]
1536 *) Add support for '--with-port=n' option to configure. [Ken Coar]
1538 *) Add support for extension methods for the Allow response header
1539 field, and an API routine for accessing r->allowed and the
1540 list of extension methods in a unified manner. [Ken Coar]
1542 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
1543 [Rob Simonson <simo@us.ibm.com>]
1545 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
1546 APACHE_XLATE builds. [Jeff Trawick]
1548 *) A configuration file parsing problem was fixed. When the
1549 configuration file started with an IfModule/IfDefine container,
1550 only the last statement in the container would be retained.
1553 Changes with Apache 2.0a5
1555 *) Perchild is serving pages after passing them to different child
1556 processes. There are still a lot of bugs, but this does work. I
1557 have made requests against the same installation of Apache, and had
1558 different servers use different user IDs to serve the responses.
1559 This change moves to using socketpair instead of an AF_UNIX socket.
1562 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
1563 It can't seem to pass between child processes yet, but I think we
1564 are closer now than before. This moves us back to using Unix
1565 Domain Sockets. [Ryan Bloom]
1567 *) libapr functions and types renamed with apr_ prefix.
1568 #include "apr_compat.h" for 1.3.x backwards compat
1571 *) Fix problems with APR sockaddr handling on Win32. It didn't always
1572 return the right information on the local socket address.
1573 [Gregory Nicholls <gnicholls@level8.com>]
1575 *) ap_recv() on Win32: Set bytes-read to 0 on error.
1576 [Gregory Nicholls <gnicholls@level8.com>]
1578 *) Add an option to not detach from the controlling terminal without
1579 going into single process mode. This allows for much easier
1580 debugging of the process startup code. [Ryan Bloom]
1582 *) ab: don't use perror() to report the failure of an APR function.
1585 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
1586 scoreboard on graceful restarts.
1589 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
1590 An invalid ap_proc_t was passed to ap_create_process().
1593 *) Allow modules to register filters. Those filters are still
1594 never called, but this is a step in the right direction.
1595 [Ryan Bloom and Greg Stein]
1597 *) Register the mod_cgid daemon process for cleanup so that it is
1598 killed at termination if it does not die when the parent gets
1599 SIGTERM. This change is to fix occasional problems where the
1600 process stays around. Bugs in similar logic in mod_rewrite and
1601 mod_include were also fixed. [Jeff Trawick]
1603 *) Fix a bug in the time handling. Basically, we were imploding a time
1604 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
1605 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
1606 uses those two fields to adjust the time value. Because of the HTTP
1607 spec, both of those values can be zero'ed out safely. This fixes
1608 the bug correctly. [Ryan Bloom]
1610 *) Fix a couple of place in the Windows code where the wrong error
1611 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
1613 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
1615 *) Added the APR_EOL_STR macro for platform dependent differences in
1616 logfiles and other raw text (such as all APR files). Fixes logfiles
1617 not terminated with cr/lf sequences in Win32. [William Rowe]
1619 *) Move all strings functions in APR to src/lib/apr/strings and create
1620 apr_strings.h for the prototypes. [Ryan Bloom]
1622 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
1623 to repeat the syscall until we stop getting EINTR. I noticed a
1624 related problem at termination (SIGTERM) on FreeBSD when using
1625 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
1626 implementation work properly with child init. Previously, ap_lock()
1627 was essentially a no-op because all children were using different
1628 locks and thus nobody ever blocked. [Jeff Trawick]
1630 *) The htdocs/ tree has been moved out of the CVS source tree into
1631 a separate area for easier development. This has NO EFFECT on
1632 end-users or Apache installations. [Ken Coar]
1634 *) Integrate the mod_dav module for WebDAV protocol handling. This
1635 adds the dav and dav_fs modules, the SDBM library, and additional
1636 XML handling utilities. [Greg Stein]
1638 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
1641 *) Update the lib/expat-lite/ library (bring forward changes from
1642 the Apache 1.3 repository). [Greg Stein]
1644 *) If sizeof(long long) == sizeof(long), then prefer long in APR
1645 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
1647 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
1648 machines where sendfile is detected, but nobody has written ap_sendfile.
1649 [Dave Hill <ddhill@zk3.dec.com>]
1651 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
1653 *) ab would start up more connections than needed, then quit when the
1654 desired number were finished. Also fixed a logic error involving
1655 ab keepalives. [Victor J. Orlikowski]
1657 *) WinNT: Implement non-blocking pipes with timeouts to communicate
1658 with CGIs. Apache 2.0a4 had non-blocking pipes but without
1659 timeouts (i.e, if a timeout was specified, the pipe reverted to
1660 a full blocking pipe). Now the behaviour is more in line with
1661 Unix non-blocking pipes.
1664 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
1665 cache open file handles along with accept socket reuse enables
1666 Apache 2.0 to serve non-keepalive requests for static files at
1667 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
1668 and Apache 2.0 will serve almost 1200 rps on my system).
1671 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
1672 supports two config directives, mmapfile (same behavious as
1673 mod_mmap_static) and cachefile. Use the cachefile directive
1674 to cache open file handles. This directive only works on systems
1675 that have implemented the ap_sendfile API. cachefile works today
1676 on Windows NT, but has not been tested on any flavors of Unix.
1679 *) Cleanup the configuration. With the last few changes the
1680 configuration process automatically:
1681 inherits information about how to build from APR. Allowing
1682 APR to inform Apache that it should or should not use -ldl
1684 Detects which mod_cgi should be used mod_cgi or mod_cgid,
1685 based on the threading model
1687 Apache calls APR's configure process before finishing it's
1688 configuration processing, allowing for more information flow
1693 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
1694 with non-zero argument makes the socket non-blocking. BeOS and
1695 OS/2 already worked this way. [Jeff Trawick]
1697 *) ap_close() now calls ap_flush() for buffered files, so write
1698 operations work a whole lot better on buffered files.
1701 *) Fix error messages issued from MPMs which explain where to change
1702 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
1705 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
1706 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
1707 now the way that the blocking state of a pipe is manipulated.
1708 ap_block_pipe() is gone. [Jeff Trawick]
1710 *) Correct the problem where the only local host name that the IP stack
1711 can discover are 'undotted' private names. If no fully qualified
1712 domain name can be identified, the default ServerName will be set to
1713 the machine's IP address string. A warning is always provided if the
1714 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
1716 *) Repair problems with config file processing which caused segfault
1717 at init when virtual hosts were defined and which caused ServerName to
1718 be ignored when there was no valid DNS setup. [Jeff Trawick]
1720 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
1722 *) Add ap_sendfile implementation for AIX
1723 [Victor J. Orlikowski]
1725 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
1726 apr_network_io.h, and apr_thread_proc.h.
1727 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
1729 *) Bring the allocation and pool debugging code back into a working
1730 state. This will need to be tested as so far it's only been used on
1733 *) Change configuration command setup to be properly typesafe when in
1734 maintainer mode. Note that this requires a compiler that can initialise
1735 unions. [Ben Laurie]
1737 *) Turn on buffering for config file reads. Part of this was to
1738 repair buffered I/O support in Unix and implement buffered
1739 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
1741 *) Win32: Fix problem where UTC offset was not being set correctly
1742 in the access log. Problem reported on news group by Jerry Baker.
1745 *) Fix segfault when reporting this type of syntax error:
1746 "</container> without matching <container> section", where
1747 container is VirtualHost or Directory or whatever.
1750 *) Prevent the source code for CGIs from being revealed when using
1751 mod_vhost_alias and the CGI directory is under the document root
1752 and a user makes a request like http://www.example.com//cgi-bin/cgi
1753 as reported in <news:960999105.344321@ernani.logica.co.uk>
1756 *) Add support for the new Beos NetwOrking Environment (BONE)
1759 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
1760 final input char is incomplete; ap_bwrite_xlate() now handles
1761 incomplete final input chars. [Jeff Trawick]
1763 *) Yet another update to saferead/halfduplex stuff -- need to ensure
1764 that a bhalfduplex call occurs before logging or else DNS and
1765 such can delay the last packet of the response. [Dean Gaudet]
1767 *) Some syscall reduction in APR on unix -- don't seek when setting
1768 up an mmap; and don't fcntl() more than once per socket.
1771 *) When mod_cgid is started as root, the cgi daemon now switches
1772 to the configured User/Group (like other httpd processes)
1773 instead of continuing as root. [Jeff Trawick]
1775 *) The prefork MPM now uses an APR lock for the accept() mutex.
1776 It has not been getting a lock at all recently. httpd -V now
1777 displays APR's selection of the lock mechanism instead of the
1778 symbols previously respected by prefork. [Jeff Trawick]
1780 *) Change the mmap() feature test to check only for existence.
1781 The previous check required features not used by Apache.
1784 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
1785 sometimes mangled. The len parm to accept() was not
1786 initialized, leading sometimes to an endless loop of failed
1787 accept() calls on OS/390 and anywhere else that failed the call
1788 if the len was negative. Use <sys/un.h> for struct sockaddr_un
1789 instead of declaring it ourselves to fix a compilation problem
1790 on Solaris. [Jeff Trawick]
1792 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
1794 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
1796 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
1798 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
1799 initialization if ALLOC_DEBUG is defined; no known symptom
1800 otherwise. [Jeff Trawick]
1802 *) Fix typo in configure script when checking for mod_so. bash
1803 doesn't seem to have a problem but /bin/sh on Solaris does.
1804 Symptom: "./configure: test: unknown operator =="
1807 *) Rebind the Win32 NT and 9x services control into the MPM.
1808 All console, WinNT SCM and Win9x pseudo-service control code is
1809 now wrapped within the WinNT MPM.
1812 *) Make a copy of getenv("PATH") before storing for later use. Some
1813 getenv() implementations use the same storage for successive calls.
1814 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
1816 *) Server Tokens work in 2.0 again. This also propogates the change
1817 to allow just the product name in the server string using
1821 Changes with Apache 2.0a4
1823 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
1824 won't need to call it. [Greg Ames, Jeff Trawick]
1826 *) Move pre_config hook call to between configuration read and config
1827 tree walk. This allows all modules to implement pre_config hooks
1828 and know that they will be called at an appropriate time.
1831 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
1834 *) Add pre-config hooks back to all modules.
1837 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
1838 ContentDigest enabled and we can't/don't mmap the file.
1841 *) We now report the correct line number for syntax errors in config
1842 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
1844 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
1845 related bugs, and changed shmem/locking to use apr API. Shared-mem
1846 is currently disabled, however, because of problems with graceful
1847 restarts. [Ronald Tschalär]
1849 *) Fix corruption of IFS variable in --with-module= handling.
1850 Depending on the user's shell or customization thereof, there
1851 would be errors generating ap_config_auto.h later in the configure
1852 procedure. [Jeff Trawick]
1854 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
1855 isn't used (as in 1.3), except that on Unix it is now logged via
1856 ap_log_rerror() instead of by the child having STDERR_FILENO refer
1857 to the error log. [Greg Ames, Jeff Trawick]
1859 *) Add '-D' argument processing for run time configuration defines.
1862 *) Organize http_main.c as independent code, such that no code or
1863 global data is exported from it. WIN32 will dynamically link it
1864 to the server core, so this will prevent mutual dependency.
1867 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
1868 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
1871 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
1872 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
1874 *) Add mod_charset_lite for configuring character set translation.
1877 *) Add '-n' option to htpasswd to make it print its user:pw record
1878 on stdout rather than having to frob a text file. [Ken Coar]
1880 *) Fix saferead. Basically, we flush the output buffer if a read on the
1884 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
1885 a conversion is single-byte only. [Jeff Trawick]
1887 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
1888 the BeOS 5.0 documentation says that shutdown doesn't work yet.
1891 *) Fix some minor errors where pid was being manipulated as an int
1892 instead of the portable pid_t. [Roy Fielding]
1894 *) Fix some error log prints that were printing the pointer to a
1895 structure rather than the pid within the structure.
1896 [Jeff Trawick, Roy Fielding]
1898 *) ab: Fix a command-line processing bug; track bad headers in
1899 err_response; support reading headers up to 2K.
1900 [Ask Bjoern Hansen <ask@valueclick.com>]
1902 *) Fix ap_resolve_env() so that it handles new function added in a prior
1903 alpha (see "Added the capability to do ${ENVVAR} constructs in the
1904 config file.") as well as the constructs used by mod_rewrite.
1905 [Paul Reder <rederpj@raleigh.ibm.com>]
1907 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
1909 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
1910 APR to perform translation, instead of accessing the hard-coded tables
1911 in 1.3's ebcdic.c. [Jeff Trawick]
1913 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
1916 *) Add the ability to hook into the config file reading phase. Basically
1917 if a directive is specified EXEC_ON_READ, then when that directive is
1918 read from the config file, the assocaited function is executed. This
1919 should only be used for those directives that must muck with HOW the
1920 server INTERPRETS the config. This should not be used for directives
1921 that re-order or replace items in the config tree. Those changes should
1922 be made in the pre-config step.
1925 *) Add mod_example to the build system.
1928 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
1929 byte character sets. [Jeff Trawick]
1931 *) Pick up various EBCDIC fixes from 1.3 (from Martin
1932 Kraemer and Oliver Reh originally according to the change log).
1935 *) Fix a couple of problems in RFC1413 support (controlled by the
1936 IdentityCheck directive). Apache did not build the request string
1937 properly and more importantly Apache would loop forever if the
1938 would-be ident server dropped the connection before sending a
1939 properly terminated response. [Jeff Trawick]
1941 *) apxs works in 2.0.
1944 *) Reliable piped logs work in 2.0.
1947 *) Introduce a hash table implementation into APR to be used for
1948 replacing tables and other random data structures in Apache.
1951 *) Add some more error reporting to htpasswd in the case of problems
1952 generating or accessing the temporary file. Also, pass in a
1953 buffer if the implementation knows how to use it (i.e., if L_tmpnam
1954 is defined). [Ken Coar]
1956 *) Configure creates config.nice now containing your configure
1957 options. Syntax: ./config.nice [--more-options]
1960 *) Fix various return code problems in APR on Win32. For most of
1961 these, APR was returning APR_EEXIST instead of GetLastError()/
1962 WSAGetLastError(). [Jeff Trawick]
1964 *) Make piped logs work again in version 2.0
1967 *) Add VPATH support to UNIX build system of Apache and APR.
1970 *) Fix ap_tokenize_to_argv to respect the const arguments that are
1974 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
1975 Patch submitted to author.
1978 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
1979 /sbin in PATH on FreeBSD (all submitted to rse previously)
1982 *) Fix building Pthread-based MPMs on OpenBSD
1983 [Sascha Schumann] PR#26
1985 *) Fix ap_readdir() problem on systems where d_name[] field in
1986 struct dirent is declared with only one byte. (This problem only
1987 affected multithreaded builds.) This caused a segfault during
1988 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
1989 least). [Jeff Trawick]
1991 *) Fix some make-portability problems on at least Tru64, Irix
1993 [Sascha Schumann] PR#18, PR#39
1995 *) Add ap_sigwait() to support old-style sigwait() on systems
1996 like OS/390 and UnixWare.
1999 *) Add POSIX-thread flags for more platforms.
2002 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
2003 (on Unix, at least) to handle resolver errors. Fix a bug in
2004 the definition of APR_ENOMEM so that ap_strerror() can spit
2005 out the correct error message for it.
2008 Changes with Apache 2.0a3
2010 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
2013 *) API: *HOOK* macros now have an AP_ prefix
2016 *) Win32: Eliminate redundant calls to initialize winsock.
2017 [Tim Costello <timcostello@ozemail.com.au>]
2019 *) Fix bugs initializing ungetchar for pipes.
2020 [Chia-liang Kao <clkao@CirX.ORG>]
2022 *) The ab program in the src/support directory is now portable using
2026 *) Support directory is being compiled when the server is built
2029 *) The configure option --with-program-name has been added to allow
2030 developers to rename the executable at configure time. This also
2031 changes the name of the config files to match the executable's name.
2034 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
2035 containing version numbers. [Martin Pool]
2037 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
2038 Unix; access_log and error_log now created with these perms; non-
2039 Unix is unaffected [Jeff Trawick]
2041 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
2042 Replaced more magic numbers with MD5_DIGESTSIZE.
2043 [William Rowe, Roy Fielding]
2045 *) Win32: Get mod_auth_digest compiling and added to the Windows
2046 build environment. Not tested and I'd be suprised if it
2047 actually works. [Bill Stoddard]
2049 *) Revamp the Win32 make environment. Makefiles have been removed and
2050 Apache.dsw created to bring together all the pieces. Create new file
2051 os/win32/BaseAddr.ref to define module base addresses (to prevent
2052 dll relocation at start-up).
2053 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
2055 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
2056 of the \015, \012, and \015\012 constants with macros.
2057 [Greg Ames <gregames@us.ibm.com>]
2059 *) Add ap_xlate_open() et al for translation of text between different
2060 character sets. The initial implementation requires iconv().
2063 *) More FAQs and answers from comp.infosystems.www.servers.unix.
2064 [Joshua Slive <slive@finance.commerce.ubc.ca>]
2066 *) CGI output is being timed out now.
2069 *) Fix the problem with dieing quietly. dupfile now takes a pool which
2070 is used by the new apr file. There is no reason to create a new file
2071 with the same lifetime as the original file.
2074 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
2075 module base addresses. This will help shooting seg faults
2076 in the field. [William Rowe <wrowe@lnd.com>]
2078 *) Update Apache on Windows documentation. Add new document
2079 describing how to compile Apache on Windows.
2080 [William Rowe <wrowe@lnd.com>]
2082 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
2083 microseconds instead of seconds. Some storage leaks and other
2084 minor bugs in related code were fixed. [Jeff Trawick]
2086 *) Win32: First cut at getting mod_isapi working under 2.0
2087 [William Rowe <wrowe@lnd.com>]
2089 *) First stab at getting mod_auth_digest working under 2.0
2090 quick change summary:
2091 - moved the random byte generation (ap_generate_random_bytes) into APR
2092 - now uses ap_time_t
2093 - compiles and runs on linux
2095 [Brian Martin <bmartin@penguincomputing.com>]
2097 *) Win32: Move the space stripping of physical service names
2098 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
2099 unresolved symbol. Add dependency checking to the
2100 CreateService call to ensure TCPIP and AFP (winsock) is started
2102 [William Rowe <wrowe@lnd.com>]
2104 *) Win32: Add code to perform latebinding on functions that may
2105 not exist on all levels of Windows where Apache runs. This
2106 is needed to allow Apache to start-up on Win95/98. All calls
2107 to non portable functions should be protected with
2108 ap_oslevel checks to prevent runtime segfaults.
2109 [William Rowe <wrowe@lnd.com>]
2111 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
2113 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
2115 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
2116 This addresses PR 1623. Still need to address timing out runaway
2117 CGI scripts. [Bill Stoddard]
2119 *) Win32: Make ap_stat Windows 95/98 friendly
2120 [William Rowe <wrowe@lnd.com>]
2122 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
2123 always fail. Need to initialise the dwOSVersionInfoSize member of the
2124 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
2127 The patch also enhances ap_get_oslevel (and the associated enum) to
2128 handle selected service packs for NT4, and adds recognition for
2129 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
2130 we can use ReadFileScatter and WriteFileGather in readwrite.c.
2131 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
2133 *) Get mod_rewrite building and running, and mod_status building for Win NT
2134 [Allan Edwards <ake@raleigh.ibm.com>]
2136 *) Patch to port mod_auth_db to the 2.0 api and also to support
2137 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
2138 2.7.7. It should work with version 1 as well but I haven't tested it.
2139 [Brian Martin <bmartin@penguincomputing.com>]
2141 *) Get APR DSO code working under Windows. Includes cross platform
2143 [Tim.Costello@BTFinancialgroup.com]
2145 *) Fix some of the Windows APR time functions.
2148 *) FAQ changes related to tidying up historical documents on the web site.
2149 [Joshua Slive <slive@finance.commerce.ubc.ca>]
2151 *) Move Windows DSO code into APR.
2154 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
2155 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
2156 at build time. At this point, the server will not compile on Windows because
2157 of the recent DSO commits. Fixing those next.
2158 [Bill Rowe & Bill Stoddard]
2160 *) Added error checking for file I/O APR routines.
2161 [Jon Travis <jtravis@covalent.net>]
2163 *) APR: Don't use the values of resolver error codes for the
2164 corresponding APR error codes. On Unix and Win32, return the
2165 proper APR error code after a resolver error. [Jeff Trawick]
2167 Changes with Apache 2.0a2
2169 *) Renamed the executable back to httpd on all platforms other
2173 *) Allow BeOS to survive restarts, log properly and a few
2174 small things it had problems with due to the way it setup
2175 users and groups. [David Reid]
2177 *) Get mod_rewrite working with APR locks
2178 [Paul Reder <rederpj@raleigh.ibm.com>]
2180 *) Actually remove the sempahore when the lock cleanup routine
2181 is called on BeOS. [David Reid]
2183 *) Clear hook registrations between reads of the config file.
2184 When DSOs are unloaded and re-loaded the old hook pointers may
2185 no longer be valid. This fix eliminates potential segfaults.
2186 [Allan Edwards <ake@raleigh.ibm.com>]
2188 *) Fix a problem with Sigfunc not being defined or bypassed
2189 if sigaction() wasn't found. [Jim Jagielski]
2191 *) Fix the locking mechanism on BSD variants. They now use fcntl
2192 locks. This allows the server to start and serve pages.
2195 *) First cut at getting the Win32 installer to work
2196 [William Rowe <wrowe@lnd.com>]
2198 *) Get htpasswd compiling under Windows
2199 [William Rowe <wrowe@lnd.com>]
2201 *) Change the log message for a bind() failure to show the
2202 interface and port number. [Jeff Trawick]
2204 *) Import the documentation from 1.3.12 and bring parts of it
2205 up-to-date with respect to the changes that have occurred
2209 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
2210 now logged correctly on BeOS.
2213 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
2214 Makefile.win includes the same user interface as the old
2216 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
2218 *) Win32 exec now uses COMSPEC environment string for command
2219 shell path resolution.
2220 [William Rowe <wrowe@lnd.com>] PR#3715
2222 *) Win32: ap_connect() was not returning correct error condition
2224 [Allen Prescott <allen@clanprescott.com>]
2226 *) Win32: ap_open() was broken on Win9x because an NT-specific
2227 flag was passed to CreateFile. ap_puts() added an unnecessary
2229 [Jeff Trawick <trawick@us.ibm.com>]
2231 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
2232 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
2233 confusing ee/et name and made all extensions language/dialect
2234 rather than country reflecting. Changed example files to
2235 explicit reflect the ISO charset and added a few common
2236 ones to the example config [dirkx]
2238 *) Extend external module capability. To use this, you call
2239 configure with --with-module=path/to/mod1,path/to/mod2,etc.
2242 *) Backported the various "default charset" fixes from 1.3.12,
2243 including the AddDefaultCharset directive. [Jim Jagielski]
2245 *) Added the capability to do ${ENVVAR} constructs in the
2246 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
2247 it does this on a line by line basis; i.e. if the envvar
2248 expands to something with spaces you have to protect it
2249 by adding quotes around it (Unless of course you expect it
2250 to contains more than one argument. Alternatively you
2251 can compile it on a per token basis; which is what people
2252 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
2253 hampers fancier hacks.
2254 [Dirk-Willem van Gulik]
2256 *) Changed the 'ErrorDocument' syntax in that it NO longer
2257 supports the asymetric
2259 ErrorDocument 301 "Some message
2261 Note the opening " quote, without a closing quote. It now
2262 has either the following syntaxes
2264 ErrorDocument XXX /local/uri
2265 ErrorDocument XXX http://valid/url
2266 ErrorDocument XXX "Some Message"
2268 The recognition heuristic is: if it has a space it
2269 is a message. If it has no spaces and starts with a /
2270 or is a valid URL then treat it that way. Otherwise it
2271 is assumed to be a message.
2273 This breaks backward compatibility but makes live a hell
2274 of a lot easier for GUI's and config file parsers.
2275 [Dirk-Willem van Gulik]
2277 *) Changed 'CacheNegotiatedDocs' from its present/not-present
2278 syntax into a 'on' or 'off' syntax. As it currently is the
2279 only non nesting token which uses NO_ARGS and thus is an
2280 absolute pain for any config interface automation. This
2281 breaks backward compatibility. [Dirk-Willem van Gulik]
2283 *) Add ability to add external modules to the build process. This is
2284 done with --with-module=/path/to/module. Modules can only be added
2285 as static modules at this point.
2288 Changes with Apache 2.0a1
2290 *) Fix FreeBSD 3.3 core dump.
2291 Basically, ap_initialize() needs to get called before
2292 create_process(), since create_process() passes op_on structure
2293 to semop() to get a lock, but op_on isn't initialized until
2294 ap_initialize() calls setup_lock(). Here is a slight
2295 rearrangement to main() which calls ap_initialize() earlier...
2296 [Jeff Trawick <trawick@us.ibm.com>]
2298 *) Enable Apache to use sendfile/TransmitFile API
2299 [Bill Stoddard, David Reid, Paul Reder]
2301 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
2305 *) Make file I/O and network I/O writev/sendv APIs consistent.
2306 Eliminate use of ap_iovec_t and use Posix struct iovec.
2307 Use seperate variable on ap_writev to set the number of iovecs
2308 passed in and number of bytes written.
2311 *) Adapt file iol to use APR functions. Replaced ap_open_file()
2312 with ap_create_file_iol(). ap_create_file_iol() requires that
2313 the file be opened prior to the call using ap_open().
2316 *) Port mod_include and mod_cgi to 2.0
2317 [Paul Reder, Bill Stoddard]
2319 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
2320 bytes_read/bytes_written is always valid (never -1). Plus
2321 some fixes to buff.c to correct problems introduced by the
2322 errno => ap_status_t changes a while back. Plus a fix to
2323 chunked encoding introduced right at the beginning of 2.0.
2326 *) Revamped UNIX build system to use autoconf and libtool.
2327 [Manoj Kasichainula, Sascha Schumann]
2329 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
2331 *) More rigorous checking of Host: headers to fix security problems
2332 with mass name-based virtual hosting (whether using mod_rewrite
2333 or mod_vhost_alias).
2334 [Ben Hyde, Tony Finch]
2336 *) Add back support for UseCanonicalName in <Directory> containers.
2337 [Manoj Kasichainula]
2339 *) Added APLOG_STARTUP log type. This allows us to write an error
2340 message without any of the date and time information. As a part
2341 of this change, I also removed all of the calls to fprintf(stderr
2342 and replaced them with calls to ap_log_error using APLOG_STARTUP
2343 writing to stderr is no longer portable, because we don't direct
2344 stderr to the error log on all platforms.
2347 *) Convert error logging functions to take errno as an argument.
2348 This makes our error logs more portable, because some Windows API's
2349 don't set errno. This change allows us to still output a valid
2350 message on all of our platforms.
2353 *) mod_mime_magic runs in 2.0-dev now.
2354 [Paul Reder <rederpj@raleigh.ibm.com>]
2356 *) sendfile has been added to APR.
2357 [John Zedlewski <zedlwski@Princeton.EDU>]
2359 *) buff.c has been converted to no longer use errno.
2360 [Manoj Kasichainula]
2362 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
2363 interface adaption to APR functions did it. [Martin Kraemer]
2365 *) Support DSOs properly on 32-bit HP-UX 11.0
2366 [Dilip Khandekar <dilip@cup.hp.com>]
2368 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
2369 [Ralf S. Engelschall]
2371 *) Cleaned APR build environment integration and bootstrap APR
2372 automatically for developers from src/Configure.
2373 [Ralf S. Engelschall]
2375 *) Fixed building of src/support/htpasswd.c
2376 [Ralf S. Engelschall]
2378 *) When generating the Location: header, mod_speling forgot
2379 to escape the spelling-fixed uri. (Forw-Port from 1.3)
2382 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
2384 *) Change all pools to APR contexts. This is the first step to
2385 incorporating APR into Apache. [Ryan Bloom]
2387 *) Move "handler not found" warning message to below the check
2388 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
2389 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
2391 *) Support line-continuation feature in config.option file and
2392 allow the loading of multiple option sections at once via
2393 ``--with-option=<section1>,<section2>,...''
2394 [Ralf S. Engelschall]
2396 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
2398 Changes with Apache MPM
2400 *) Use asynchronous AcceptEx() and a completion port to accept and
2401 dispatch connections to threads in Windows NT/2000.
2404 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
2407 *) Implement the APACI --with-option facility
2408 (per default used the config.option file).
2409 [Ralf S. Engelschall]
2411 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
2413 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
2414 Replace pre_connection module call with a register_hook call and
2415 implement pre_connection as a hook. The intent is that these hooks will
2416 be extended to allow Apache to be multi-protocol, and also to allow the
2417 calling order to be specified on a per-hook/per-module basis.
2420 *) Implement mpm_* methods as "modules". Each method gets its own
2421 subdir in src/modules (eg: src/modules/prefork). Selection
2422 of method uses Rule MPM_METHOD. [Jim Jagielski]
2424 *) Port the hybrid server from the apache-apr repository as
2425 mpm_mpmt_pthread. [Manoj Kasichainula]
2427 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
2428 amongst the unix MPMs.
2430 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
2431 signal handling for the new world order. [Dean Gaudet]
2433 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
2434 of alloc.c for now. [Dean Gaudet]
2436 *) Handle partial large writes correctly. [Ben Laurie]
2438 *) Eliminate conn_rec's pointer to server. All it knows is the base server
2439 based on IP/port. [Ben Laurie]
2441 *) Port a bunch of modules to the new module structure.
2442 ["Michael H. Voase" <mvoase@midcoast.com.au>]
2444 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
2446 *) Basic restructuring to introduce the MPM concept; includes various
2447 changes to the module API... better described by
2448 docs/initial_blurb.txt. [Dean Gaudet]
2450 Changes with Apache pthreads
2452 *) New buff option added: BO_TIMEOUT. It describes the timeout for
2453 buff operations (generally over a network).
2454 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
2456 *) Created http_accept abstraction. Added 4 new functions (not exported):
2457 init_accept(), begin_accepting_requests(), get_request(),
2458 stop_accepting_requests() [Bill Stoddard]
2460 *) Fix to ap_rprintf call that allows mod_info to work properly.
2461 [James Morris <jmorris@intercode.com.au>]
2463 *) user and ap_auth_type fields were moved from connection_rec to
2464 request_rec. [Ryan Bloom]
2466 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
2467 needed in a threaded server.
2469 *) Initial pthread implementation from from Dean's apache-nspr code.
2470 [Bill Stoddard, Ryan Bloom]
2473 Changes with Apache 1.3.9
2475 *) Remove bogus error message when a redirect doesn't set Location.
2476 Instead, use an empty string to avoid coredump if the error message
2477 was supposed to include a location. [Roy Fielding]
2479 *) Don't allow configure to include mod_auth_digest unless it is
2480 explicitly requested, even if the user asked for all modules.
2483 *) Translate module names to dll names for OS/2 so that they are no more
2484 than 8 characters long and have an extension of "dll" instead of "so".
2487 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
2488 Fix test-compile check to check for randbyte instead of trand32.
2489 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
2490 and tweak to make Amaya happier. [Ronald Tschalär]
2492 *) Ensure that the installed expat include files are world readable,
2493 just like the other header files. [Martin Kraemer]
2495 *) Fixed generated AddModule adjustments in APACI's `configure' script
2496 in order to allow (new) modules like mod_vhost_alias to be handled
2497 correctly (which was touched by the adjustments for mod_alias).
2498 [Ralf S. Engelschall]
2500 *) For binary builds, add -R flag to apachectl to work around the lack of
2501 an absolute path to the ./libexec directory where the libhttp.ep file
2502 is needed for SHARED_CORE architectures. [Randy Terbush]
2504 *) WIN32: Create the CGI script process as DETACHED. This may solve the
2505 problem observed by some Win95/98 users where they get CGI script
2506 output sent to the console. [Bill Stoddard]
2508 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
2509 routines are now called ap_base64* and are 'plain' (i.e., no
2510 pool access or anything clever). Inside util.c the routines acting
2511 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
2512 The oddly named ap_uuencode(), ap_uudecode() are kept around for
2513 now but deprecated. [dirkx]
2515 *) Clean up the base64 and SHA1 additions and make sure they are
2516 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
2517 files. [Roy Fielding]
2519 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
2520 checking. Allow compiling on VS 6.0. [Randy Terbush]
2522 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
2524 *) Use TestCompile to search for the truerand library (rather than blindly
2525 assuming its existence). If it is not found, complain (but do not
2526 exit - yet). [Martin Kraemer]
2528 *) We forgot to add the new exported function names to
2529 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
2531 *) Add description of -T command-line option to usage().
2532 [Ralf S. Engelschall]
2534 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
2535 searched only AFTER libap has been searched, because libap needs
2536 some symbols from libos. [Martin Kraemer]
2538 *) Fix conflict with original mod_digest related to the symbol of the
2539 module dispatch list (which has to be unique for DSO and follow the
2540 usual conventions for the installation procedure).
2541 [Ralf S. Engelschall]
2543 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
2544 for other platforms as well. [Martin Kraemer]
2546 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
2547 types by AP_LONG and replace reference to renamed variable 'ubuf'
2548 by 'buffer'. [Martin Kraemer]
2550 Changes with Apache 1.3.8 [not released]
2552 *) Flush the output buffer immediately after sending an error or redirect
2553 response, since the result may be needed by the client to abort a
2554 long data transfer or restart a series of pipelined requests.
2555 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
2557 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
2558 [Ian Turner <iant@sequent.com>] PR#4735
2560 *) Local struct mmap in http_core.c conflicted with system structure
2561 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
2563 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
2564 [Ronald Tschalär <ronald@innovation.ch>]
2566 *) Fix a memory leak where the module counts were getting messed
2567 up across restarts. [David Harris <dharris@drh.net>]
2569 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
2570 properly in mod_access.
2571 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
2573 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
2574 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
2576 *) PORT: Support for compaq/tandem/com.
2577 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
2579 *) Added SHA1 password encryption support to easy migration from
2580 Netscape servers. See support/SHA1 for more information.
2581 Caused the separation of ap_md5.c into md5, sha1 and a general
2582 ap_checkpass.c with just a validate_passwd routine. Added a
2583 couple of flags to support/htpasswd. Some reuse of the to64()
2584 function; hence renamed to ap_to64().
2585 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
2587 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
2588 with ASCII/EBCDIC conversions in "ident" query.
2589 [David McCreedy <McCreedy@us.ibm.com>]
2591 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
2592 Change "Power Macintosh" to Power* so if uname prints "Power Book"
2593 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
2595 *) Fix SIGSEGV on some systems because the Vary fix below included
2596 a call to table_do with a variable argument list that was not
2597 NULL terminated. Replaced with better implementation. [Roy Fielding]
2599 Changes with Apache 1.3.7 [not released]
2601 *) The "Vary" response header field is now sanitised right before
2602 the header is sent back to the client. Multiple "Vary" fields
2603 are combined, and duplicate tokens (e.g., "Vary: host, host" or
2604 "Vary: host, negotiate, host, accept-language") are reduced to
2605 single instances. This is a better solution than the force-no-vary
2606 one (which is still valid for clients that can't cope with Vary
2607 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
2609 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
2611 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
2612 least on Linux and FreeBSD for now.
2615 *) Win32: More apache -k restart work. Restarts are now honored
2616 immediately and connections in the listen queue are -not- lost.
2617 This is made possible by the use of the WSADuplicateSocket()
2618 call. The listeners are opened in the parent, duplicated, then
2619 the duplicates are passed to the child. The original listen sockets
2620 are not closed by the parent across a restart, thus the listen queue
2622 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2624 *) Fix handling of case when a client has sent "Expect: 100-continue"
2625 and we are going to respond with an error, but get stuck waiting to
2626 discard the body in the pointless hope of preserving the connection.
2627 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
2629 *) Fix 'configure' to work correctly with SysV-based versions of
2630 'tr' (consistent with Configure's use as well). [Jim Jagielski]
2632 *) apxs: Add "-S var=val" option which allows for override of CFG_*
2633 built-in values. Add "-e" option which works like -i but doesn't
2634 install the DSO; useful for editing httpd.conf with apxs. Fix
2635 editing code so that multiple invocations of apxs -a will not
2636 create duplicate LoadModule/AddModule entries; apxs can now be
2637 used to re- enable/disable a module. [Wilfredo Sanchez]
2639 *) Win32: Update the server to use Winsock 2. Specifically, link with
2640 ws2_32.lib rather than wsock32.lib. This gives us access to
2641 WSADuplcateSocket() in addition to some other enhanced comm APIs.
2642 Win 95 users may need to update their TCP/IP stack to pick up
2643 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
2644 [Bill Stoddard stoddard@raleigh.ibm.com]
2646 *) Win32: Redirect CGI script stderr (script debug info) into the
2647 error.log when CGI scripts fail. This makes Apache on Win32
2648 behave more like Unix.
2649 [Bill Stoddard stoddard@raleigh.ibm.com]
2651 *) Fixed `httpd' usage display: -D was missing.
2652 [Ralf S. Engelschall] PR#4614
2654 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
2655 [Ralf S. Engelschall] PR#4561, PR#4562
2657 *) OS/2: Fix problem with accept lock semaphores where server would die with
2658 "OS2SEM: Error 105 getting accept lock. Exiting!"
2659 [Brian Havard] PR#4505
2661 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
2662 [Randy Terbush <randy@covalent.net>]
2664 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
2665 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
2667 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
2668 command potentially _is_ GCC. [Ralf S. Engelschall]
2670 *) Fix apxs build issues on AIX
2671 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
2673 *) DocumentRoot Checking: Under previous versions, when Apache
2674 first started up, it used to do a stat of each DocumentRoot to
2675 see if it existed and was a directory. If not, then an error
2676 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
2677 does not exist, you will get error messages in error_log. If
2678 the '-t' command line option is used (to check the configuration)
2679 the check of DocumentRoot IS performed. An additional command
2680 line option, '-T', has been added if you want to avoid the
2681 DocumentRoot check even when checking the configuration.
2684 *) Win32: The query switch "apache -S" didn't exit after showing the
2685 vhost settings. That was inconsistent with the other query functions.
2686 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
2688 *) Win32: Changed behaviour of apache -k restart.
2689 Previously, the server would drain all connections in the stack's
2690 listen queue before honoring the restart. On a busy server, this
2691 could take hours. Now, a restart is honored almost immediately.
2692 All connections in Apache's queues are handled but connections in
2693 the stack's listen queue are discarded. Restart triggered by
2694 MaxRequestPerChild is unchanged.
2695 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2697 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
2698 the accept loop. Good for a 5% performance boost. Cleaned up
2699 parent/child process management code.
2700 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2702 *) Added ceiling on file size for memory mapped files.
2703 [John Giannandrea <jg@meer.net>] PR#4122
2705 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
2706 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
2707 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
2709 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
2710 use this at least for Expat. [Ralf S. Engelschall]
2712 *) Allow .module files to specify libraries with Lib:.
2715 *) Allow SetEnvIf[NoCase] to test environment variables as well
2716 as header fields and request attributes. [Ken Coar]
2718 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
2719 content-types are "text/html;parameters". PR#4524 [Ken Coar]
2721 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
2722 never accepted into any standard, and it opens up certain DoS
2723 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
2725 *) TestCompile updated. We can now run programs and output the
2726 results during the Configure process. [ Jim Jagielski]
2728 *) The source is now quad (long long) aware as needed. Specifically,
2729 the Configure process determines the correct size of off_t and
2730 *void. When the OS/platform/compiler supports quads, ap_snprintf()
2731 provides for the 'q' format qualifier (if quads are not available,
2732 'q' is silently "demoted" to long). [Jim Jagielski]
2734 *) When the username or password fed to htpasswd is too long, include the
2735 size limit in the error message. Also report illegal characters
2736 (currently only ':') in the username. Add the size restrictions
2737 to the man page. [Ken Coar]
2739 *) Fixed the configure --without-support option so it doesn't result in
2740 an infinite loop. [Marc Slemko]
2742 *) Piped error logs could cause a segfault if an error occured
2743 during configuration after a restart.
2744 [Aidan Cully <aidan@panix.com>] PR#4456
2746 *) If a "Location" field was stored in r->err_headers_out rather
2747 than r->headers_out, redirect processing wouldn't find it and
2748 the server would core dump on ap_escape_html(NULL). Check both
2749 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
2750 if Location isn't set. [Doug MacEachern, Ken Coar]
2752 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
2753 of the Expat 1.0.2 distribution. [Greg Stein]
2755 *) Replace regexec() calls with calls to a new API stub function
2756 ap_regexec(). This solves problems with DSO modules which use the regex
2757 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
2759 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
2760 environment variables can be set according to the protocol version
2761 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
2763 *) Add DSO support for OpenStep (Mach 4.2) platform.
2764 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
2766 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
2767 [Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
2769 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
2770 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
2772 *) Better DSO flags recognition on NetBSD platforms using ELF.
2773 [Todd Vierling <tv@pobox.com>] PR#4310
2775 *) Always log months in english format for %t in mod_log_config.
2776 [Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
2778 *) Support for server-parsed and multiview-determined ReadmeName and
2779 HeaderName files in mod_autoindex. Removed the restriction on
2780 "/"s in ReadmeName and HeaderName directives since the *sub_req*
2781 routines will deal with the access issues. (It's now possible to
2782 have {site|group|project|customer|...} wide readmes and headers.)
2783 [Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
2786 *) When stat() fails, don't assume anything about the contents of
2787 the struct stat. [Ed Korthof <ed@bitmechanic.com>]
2789 *) It's OK for a semop to return EINTR, just loop around and try
2790 again. [Dean Gaudet]
2792 *) Fix configuration engine re-entrant hangups, which solve a
2793 handful of problems seen with mod_perl <Perl> configuration sections
2794 [Salvador Ortiz Garcia <sog@msg.com.mx>]
2796 *) Mac OS and Mac OS X Server now use the appropriate custom layout
2797 by default when building with APACI; allow for platform-specific
2798 variable defaults in configure. [Wilfredo Sanchez]
2800 *) Do setgid() before initgroups() in http_main; some platforms
2801 zap the grouplist when setgid() is called. This was fixed in
2802 suexec earlier, but the main httpd code missed the change.
2803 [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2579
2805 *) Add recognition of .tgz as a gzipped tarchive.
2806 [Bertrand de Singly <bertrand.de-singly@polytechnique.fr>] PR#2364
2808 *) mod_include's fsize/flastmod should allow only relative paths, just
2809 like "include file". [Jaroslav Benkovsky <benkovsk@pha.pvt.cz>]
2811 *) OS/2: Add support for building loadable modules using DLLs.
2814 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
2817 *) Fix minor but annoying bug with the test for Configuration.tmpl
2818 being newer than Configuration so that it is less likely to fail
2819 when using APACI and shadow sources. [Wilfredo Sanchez]
2821 *) PORT: Add initial support for Mac OS (versions 10.0 and
2822 greater). Use Mac OS X Server layout for now. Clean up dyld code
2823 in unix/os.c, and don't install the dyld error handlers, which
2824 are no longer needed in Mac OS. [Wilfredo Sanchez]
2826 *) Rename Rhapsody layout to "Mac OS X Server". Change install
2827 locations to appropriate ones for user-built (as opposed to
2828 system) installs. [Wilfredo Sanchez]
2830 *) Modify mod_autoindex's handling of AddDescription so that the
2831 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
2833 *) Add functionality to the install-bindist.sh script created by
2834 binbuild.sh to use tar when copying distribution files to the
2835 serverroot. This allows upgrading an existing installation
2836 without nesting the new distribution in the old.
2838 install-bindist.sh now detects the local perl5 path to install
2839 apxs and dbmmanage with proper path to perl interpreter.
2841 Add an install-binsupport target which copies the source files
2842 for apxs and dbmmanage to bindist to allow these scripts to
2843 be properly installed relative to the destination serverroot.
2844 [Randy Terbush, Covalent Technologies, randy@covalent.net]
2846 *) Fix intermittent SEGV in ap_proxy_cache_error() in

2858 *) Force the LANG envariable to the known state of "C" so that we
2859 have assurance about how string manipulators (e.g., tr) will
2860 function. [Ken Coar] PR#1630
2862 *) Add a directive to allow customising of the tracking cookie name.
2863 [Ken Coar] PR#2921, 4303
2865 *) Add "force-no-vary" envariable to allow servers to work around
2866 clients that choke on "Vary" fields in the response header.
2867 [Ken Coar, Dmitry Khrustalev <dima@zippy.machaon.ru>] PR#4118
2869 *) Fixed a bug in mod_dir that causes a child process will infinitely
2870 recurse when it attemps to handle a request for a directory wnd the
2871 value of the DirectoryIndex directive is a single dot. Also likely
2872 to happen for anyother values of DirectoryIndex that will map back
2873 to the same directory. The handler now only considers regular files

2886 *) Add APACI --without-execstrip option which can be used to disable the
2887 stripping of executables on installation. This is very important for DSO
2888 and debugging situations. [Ralf S. Engelschall]
2890 *) Add support for OS/2 (case insenstive filesystem, .exe suffix, etc)
2891 to APACI files and related scripts.

2906 *) Make sure RewriteLock can be used only in the global context, (i.e.
2907 outside of any <VirtualHost> sections) because it's a global facility of
2908 the rewrite engine. [Ralf S. Engelschall]
2910 *) Fix the ownership delegation for proxy directory under `make install'.

2913 *) APACI would not correctly build suexec. [Maria Verina
2914 <mariav@icgeb.trieste.it>] PR#4260
2916 *) mod_mime_magic passed only the first 4k of a file to
2917 uncompress/gzip, but those tools sometimes do not produce
2918 any output unless a sufficient portion of the compressed

2954 [Peter 'Luna' Altberg <peter@altberg.nu>, Ronald Tschalär]
2956 *) Make {Set,Unset,Pass}Env per-directory instead of per-server.
2959 *) Correct an apparent typo: on the Windows and MPE platforms, the
2960 htpasswd utility was limiting passwords to only 8 characters.
2963 *) EBCDIC platforms: David submitted patches for two bugs in the
2964 MD5 digest port for EBCDIC machines:
2965 a) the htdigest utility overwrote the old contents of the digest file
2966 b) the Content-MD5 header value (ContentDigest directive) was wrong
2967 when the returned file was not converted from EBCDIC, but was a
2968 binary (e.g., image file) in the first place.
2969 [David McCreedy <mccreedy@us.ibm.com>]
2971 *) support/htpasswd now permits the password to be specified on the
2972 command line with the '-b' switch. This is useful when passwords
2973 need to be maintained by scripts -- particularly in the Win32
2974 environment. [Ken Coar]
2976 *) Win32: Win32 multiple services patch. Added capability to install and
2977 run multiple copies of apache as individual services.
2980 apache -n apache1 -i -f c:/httpd.conf
2981 Installs apache as service 'apache1' and associates c:/httpd.conf
2984 Starts apache1 service.
2986 Stops apache1 service
2989 apache -n apache2 -i
2990 Installs apache as service 'apache2'. httpd.conf is located under
2991 the default server root (/apache/conf/httpd.conf).
2993 Starts apache2 service.
2996 apache -n apache3 -i -d c:/program files/apache

3002 Restart apache2 service
3004 [Keith Wannamaker, Ken Parzygnat, Bill Stoddard]
3006 *) Correct the signed/unsigned character handling for the MD5 routines;
3007 mismatches were causing compilation problems with gcc -pedantic and
3008 in the TPF cross-compilation. [Ken Coar]
3010 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
3011 a roughly 5 fold speed up. [Brian Havard]
3013 *) proxy ftp: instead of using the hardwired string "text/plain" as
3014 a fallback type for files served by the ftp proxy, use the
3015 ap_default_type() function to determine the configured type.
3016 This allows for special configurations like
3017 <Directory proxy:ftp://some.host>
3018 DefaultType gargle/blurb
3020 Additionally, add the Content-Encoding: header to FTP proxy replies
3021 when the encoding is defined (by the AddEncoding directive).
3022 Because it was missing, it was almost impossible to browse compressed
3023 files using the FTP proxy (works now perfectly in Communicator).
3024 The ftp proxy now also returns the Date: and Server: header lines (if not
3025 much else... This code is "somewhat" broken) like normal requests do.
3028 *) Be more smart in APACI's configure script when determining the UID/GID
3029 for User/Group directives and use the determined UID/GID to initialize
3030 the permissions on the proxycachedir.
3031 [Dirk-Willem van Gulik, Ralf S. Engelschall]
3033 *) Changed the forking-prior-to-cleanup in the proxy module to first
3034 check wether it actually needs to collect garbage. This reduces
3035 the number of fork()s from one/request to just the odd one an hour.
3036 [Dirk-Willem van Gulik]
3038 *) Added proxy, auth and header support to src/support/ab.c. Added a

3046 [Randy Terbush, Covalent Technologies]
3048 *) Fix sed-substitutions in `make install': path elements like `httpd/conf'
3049 (for instance from an APACI configure --sysconfdir=/etc/httpd/conf
3050 option) were substituted with $(TARGET).conf, etc. Same for other strings
3051 with dots where the dot wasn't matched as plain text.

3059 Changes with Apache 1.3.6
3061 *) Removed new PassAllEnv code due to DSO problems. [Lars Eilebrecht]
3063 Changes with Apache 1.3.5 [not released]
3065 *) M_INVALID needed a value within the scope of METHODS so that unknown
3066 methods can be access controlled. [Roy Fielding] PR#3821
3068 *) Added PassAllEnv; makes server's entire environment available
3069 to CGIs and SSIs executed within directive's scope. [Ken Coar]
3071 *) ap_uuencode() always added two trailing '='s and encoding of
3072 8 bit characters on a machine with signed char may produced
3073 incorrect results. Additionally ap_uuencode() should now
3074 work correctly on EBCDIC platforms.
3075 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
3077 *) WIN32: Binary installer now runs the configuration DLL before
3078 the reboot prompt (which is only given if MSVCRT.DLL system
3079 DLL is new or updated). This should avoid the configuration
3080 directory being empty after installation. [Paul Sutton]
3081 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988

3085 the Apache service on NT. [Paul Sutton] PR#3741
3087 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
3089 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
3090 have been reported with flock() locking (probably related to kernel
3091 version). [Dean Gaudet] PR#2723, 3531
3093 *) Using APACI, the main config file (usually httpd.conf) was
3094 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez

3104 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
3105 for 8-bit safeness. [Dean Gaudet]
3107 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
3108 because SPARCs have a small machine-specific maximum size for the Global
3109 Offset Table which is often exceeded when compiling one of the larger
3110 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
3112 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
3113 DSO/DLL section because it's a directive from mod_status and isn't
3114 available before the DLL of mod_status is loaded.
3115 [Martin POESCHL <mpoeschl@gmx.net>] PR#3936
3117 *) SECURITY: Fix a bug in the calculation of the buffer size for the line

3127 [John Tobey <jtobey@banta-im.com>] PR#3983
3129 *) Let APACI's configure script correctly complain for unknown --enable-XXX
3130 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
3132 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
3133 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
3134 possible buffer overflows. [Ralf S. Engelschall]
3136 *) Remove no longer used non-API function ap_single_module_init().
3137 [Ralf S. Engelschall]
3139 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
3142 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
3143 to make platform installations easier. [Wilfredo Sanchez]
3145 *) In configure, do not append the target name to the directory path if
3146 the path already contains "apache". [Ralf S. Engelschall]
3148 *) SIGPIPE is now ignored by the server core. The request write routines
3149 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
3150 correctly check for output errors and mark the connection as aborted.
3151 Replaced many direct (unchecked) calls to ap_b* routines with the
3152 analogous ap_r* calls. [Roy Fielding]
3154 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
3155 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
3156 Furthermore map lookups for non-existent keys are now cached as well.
3157 Additionally "txt" maps are now parsed with simple string functions
3158 instead of using ap_pregcomp(). As a side effect a bug that prevented
3159 the usage of keys containing the "," character was fixed.
3160 The changes drastically improve the performance when large rewrite maps
3162 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
3164 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
3165 other than GET, and const'd the definition of method in request_rec.
3168 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
3170 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
3171 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
3173 *) Add %V to mod_log_config, this logs the hostname according to the
3174 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
3175 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
3177 *) Add support for \n and \t to mod_log_config, can be used to produce
3178 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
3180 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
3182 *) Added informative error messages for failed munmap() and fseek() calls
3183 in http_core.c. [John Bley, Roy Fielding]
3185 *) Added some informative error messages for some failed malloc()
3186 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
3188 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
3189 is removed. This allows <Directory proxy:*> directives to work and
3190 prevents invalid requests from killing the process.
3191 [Brian Havard <brianh@kheldar.apana.org.au>]
3193 *) Reorganised FAQ document.
3194 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497
3196 *) src/support/: The ApacheBench benchmark program was overhauled by
3197 David N. Welton: you can now have it generate an HTML TABLE, presumably
3198 for integration into other HTML sources. David updated the ab man page
3199 as well and added some missing descriptions. Thanks!
3200 [David N. Welton <davidw@prosa.it>]
3202 *) Win32: The filename validity checker now allows filenames containing
3203 characters in the range 0x80 to 0xff (for example accented characters).
3204 [Paul Sutton] PR#3890
3206 *) Added conditional logging based upon environment variables to
3207 mod_log_config. mod_log_referer and mod_log_agent
3208 are now deprecated. [Ken Coar]
3210 *) Allow apache acting as a proxy server to relay the real
3211 reason of a failure to a client rather than the "internal
3212 server error" it does currently. The general exposure mechanism
3213 can be triggered by any module by setting the "verbose-error-to"
3214 note to "*"; this allows more than just proxy errors to be exposed.
3215 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
3217 *) Moved man pages for ab and apachectrl to section 8.
3218 [Wilfredo Sanchez, Roy Fielding]
3220 *) Added -S option to install.sh so that options can be passed to
3221 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
3223 *) Tweak modules Makefile generated by Configure so that it handles
3224 the test case of no modules being selected. [chaz@reliant.com]
3226 *) Added a <LimitExcept method ...> sectioning directive that allows
3227 the user to assign authentication control to any HTTP method that
3228 is *not* given in the argument list; i.e., the logical negation
3229 of the <Limit> directive. This is particularly useful for controlling
3230 access on methods unknown to the Apache core, but perhaps known by
3231 some module or CGI script. [Roy Fielding, Tony Finch]
3233 *) Prevent apachectl from complaining if the PIDFILE exists but
3234 does not contain a process id, as might occur if the server is
3235 being rapidly restarted. [Wilfredo Sanchez]
3237 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
3239 *) Entity tag comparisons for If-Match and If-None-Match were not being
3240 performed correctly -- weak tags might cause false positives. Also,
3241 strong comparison wasn't properly enforced in all cases.
3242 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
3244 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
3247 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
3248 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
3250 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
3251 to util.c for parsing an HTTP header field value to extract the next
3252 list item, taking into account the possible presence of nested comments,
3253 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
3254 insignificant whitespace and lowercases non-quoted tokens.
3255 [Roy Fielding] PR#2065
3257 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
3258 code different from 500. This allows the proxy to, e.g., return
3259 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
3261 *) Fix ordering of language variants for the case where the traditional
3262 negotiation algorithm is being used with multiple language variants
3263 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
3265 *) Do not round the TCN quality calculation to 5 decimal places,
3266 unlike RFC 2296, because the calculation might need 12 decimal places
3267 to get the right result. [Roy Fielding]
3269 *) Remove unused code to disable transparent negotiation when
3270 negotiating on encoding only, as we now handle encoding too
3271 (though this is nonstandard for TCN), remove charset=ISO-8859-1
3272 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
3273 some debugging statements within mod_negotiation. [Koen Holtman]
3275 *) Fixed a rare memory corruption possibility in mod_dir if the index
3276 file is negotiable and no acceptable variant can be found.
3277 [Dean Gaudet, Roy Fielding, Martin Kraemer]
3279 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
3280 searching the Win32 registry for script interpreters.
3283 *) Win32: The compiled-in default filename for the error log is now
3284 error.log, which matches the default in the distributed httpd.conf.
3287 *) Win32: Any error messages from -i or -u command line options are now
3288 displayed on the console output rather than sent to the error log.
3289 Also the "Running Apache..." message is not output unless Apache is
3290 going to serve requests. [Paul Sutton]
3292 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
3293 and use a private significator ('$apr1$') to mark passwords as
3294 being smashed with our own algorithm. Also abstract the password
3295 checking into a new ap_validate_password() routine. [Ken Coar]
3297 *) Win32: The filename validity checker now allows "COM" but refuses
3298 access to "COM1" through "COM4". This allows filenames such
3299 as "com.name" to be served. [Paul Sutton] PR#3769.
3301 *) BS2000: Adapt to the new ufork() system call interface which will
3302 make subtasking easier on the OSD/POSIX mainframe environment.
3305 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
3306 ap_compat.h. [David White <david@persimmon.com>] PR#3725
3308 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
3309 use `.db' instead of `.pag' not only for FreeBSD, but also when
3310 the NDBM library looks like Berkeley-DB based.
3311 [Ralf S. Engelschall] PR#3773
3313 *) Add ability to handle DES or MD5 authentication passwords.
3314 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
3316 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
3318 *) SECURITY: Avoid some buffer overflow problems when escaping
3319 quoted strings. (This overflow was on the heap and we believe
3320 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
3322 *) Let src/Configure be aware of CFLAGS options starting with plus
3323 signs as it's the case for the HP/UX compiler.
3324 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
3326 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
3327 and check to see if the tar we wind up with supports '-h'.
3328 [Jim Jagielski] PR#3671
3330 *) A consistent and conservative style for all shell scripts has been
3331 implemented. Basically, all shell string tests use the traditional
3332 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
3333 to protect against bare null variable strings (ie: wrapping both
3334 sides with double quotes and prepending 'x'). 'x' was chosen
3335 because it's more universal and hopefully easier for old shell
3336 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
3339 *) The status module now prints out both the main server generation as
3340 well as the generation of each process. Also, the vhost info is
3341 printed with '?notable'. [Jim Jagielski]
3343 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
3344 and this makes its functions available to things in src/support.
3347 Changes with Apache 1.3.4
3349 *) Renamed macros status_drops_connection to ap_status_drops_connection
3350 and vestigial scan_script_header to ap_scan_script_header_err,
3351 mostly for aesthetic reasons. [Roy Fielding]
3353 *) The query switch "httpd -S" didn't exit after showing the
3354 vhost settings. That was inconsistent with the other query functions.
3357 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
3358 filename to the end of the STANDARD_MODULE_STUFF. Its
3359 presence at the beginning prevented reporting of the filename
3360 for modules compiled before 1 January 1999. [Ken Coar]
3362 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
3363 to detect and prevent access to special DOS device file names.
3364 [Paul Sutton, Ken Parzygnat]
3366 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
3367 and Makefile_win32_debug.txt (debug build) that work on Win95.
3368 Run each of the following from the src directory:
3369 nmake /f Makefile_win32.txt # compiles normal build
3370 nmake /f Makefile_win32.txt install # compiles and installs
3371 nmake /f Makefile_win32.txt clean # removes compiled junk
3372 nmake /f Makefile_win32_debug.txt # compiles debug build
3373 nmake /f Makefile_win32_debug.txt install
3374 nmake /f Makefile_win32_debug.txt clean
3377 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
3378 to build binary distributions. [Lars Eilebrecht]
3380 *) IndexOptions SuppressColumnSorting only turned off making
3381 the column headers anchors; you could still change the display
3382 order by manually adding a '?N=A' or similar query string to the
3383 URL. Now SuppressColumnSorting locks in the sort order so
3384 it can't be overridden this way. [Ken Coar]
3386 *) Added IndexOrderDefault directive to supply a default sort order
3387 for FancyIndexed directory listings. [Ken Coar] PR#1699
3389 *) Change the ap_assert macro to a variant that works on all platforms.
3390 [Richard Prinz <richard.prinz@cso.net>] PR#2575
3392 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
3393 search for an underscore on dlsym() (as it's already the case
3394 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
3396 *) Small fix for mod_env.html: The module was documented as to be _not_
3397 compiled into Apache per default, although it _IS_ compiled into
3398 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
3400 *) Instead of fixing a bug in the generation procedure for config.status (a
3401 backslash was missing) we remove the bug together with it's complete
3402 context because the special cases of the past can now no longer occur
3403 because of the recent magic for the --with-layout default.
3404 [Ralf S. Engelschall] PR#3590
3406 *) Make top-level Makefile aware of a parallel build procedures (make -j) by

3411 *) Fix installation procedure: Now that os-inline.c is actually used (a
3412 recently fixed bug prevented this) we need to also install os-include.c
3413 in addition to os.h into the PREFIX/include/ location or building of
3414 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
3416 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
3417 allow us to distinguish between a garbled DSO (or even a file which isn't
3418 an Apache module DSO at all) and a DSO which doesn't match the current
3419 Apache API. [Ralf S. Engelschall] PR#3152
3421 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
3422 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
3423 match case insensitive (this especially avoids nasty patterns like
3424 `[tT][eE][sS][tT]'). Second two additional internal map functions
3425 `escape' and `unescape' were added which can be used to escape/unescape
3426 to/from hex-encodings in URLs parts (this is especially useful in
3427 combination with map lookups).
3428 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]

3431 forgotten (because it was a macro) in the symbol renaming process.
3432 [Ralf S. Engelschall]
3434 *) Fix some inconsistencies related to the scopes of directives. The only
3435 user visible change is that the directives `UseCanonicalName' and
3436 `ContentDigest' now use the (more correct) `Options' scope instead of
3437 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
3439 *) Using DSO, the Server token was being mangled. Specifically, the
3440 module's token was being added first before the Apache token. This
3441 has been fixed. [Jim Jagielski]
3443 *) Major overhaul of mod_negotiation.c, part 2.
3444 - properly handle "identity" within Accept-Encoding.
3445 - allow encoded variants in RVSA negotiation and let them appear in
3446 the Alternates field using the non-standard "encoding" tag-list.
3447 - fixed both negotiation algorithms so that an explicitly accepted
3448 encoding is preferred over no encoding if "identity" is not
3449 included within Accept-Encoding.
3450 - added ap_array_pstrcat() to alloc.c for efficient concatenation
3451 of large substring sequences.
3452 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
3455 *) Major overhaul of mod_negotiation.c, part 1.
3456 - cleanups to mod_negotiation comments and code structure
3457 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
3458 support for everything in the upcoming HTTP/1.1
3459 revision (draft-ietf-http-v11-spec-rev-06.txt).
3460 - language tag matching also handles tags with more than 2
3462 - empty Accept, Accept-Language, Accept-Charset headers are
3463 processed correctly; previously an empty header would make all
3464 values acceptable instead of unacceptable.
3465 - allowed for q values in Accept-Encoding
3466 - added support for transparent content negotiation (rfc2295 and
3467 rfc2296) (though we do not implement all features in these drafts,
3468 e.g. no feature negotiation). Removed old experimental version.
3469 - implemented 'structured entity tags' for better cache correctness
3470 (structured entity tags ensure that caches which can deal with Vary
3471 will (eventually) be updated if the set of variants on the server
3473 - this involved adding a vlist_validator element to request_rec
3474 - this involved adding the ap_make_etag() function to the global API
3475 - modified guessing of charsets used by Apache negotiation algorithm
3476 to guess 'no charset' if the variant is not a text/* type
3477 - added code to sort multiviews variants into a canonical order so that
3478 negotiation results are consistent across backup/restores and mirrors
3479 - removed possibility of a type map file resolving to another type map
3480 file as its best variant

3507 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
3510 *) Update APXS manual page: some -q option arguments were missing
3511 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
3513 *) Cleanup the command line options: `-?' was documented to show
3514 the usage list but does it with an error because `?' is not a valid
3515 command. OTOH a lot of users expect `-h' to print such a usage list and
3516 instead are annoyed for ages by our huge unreadable list of directives.
3517 So we now changed the command line options this way:
3519 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
3520 very similar to the popular linker option.
3522 Intent: while -l gives the small list of modules, -L now gives the
3523 large list of directives implemented by these modules. This is also
3524 consistent with -v (short version info) and -V (large version info).
3526 Intent: it's now the expected option ;-)
3527 The manual page was adjusted accordingly.

3530 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
3531 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
3533 *) Removed recently introduced bugs and disfigurements in APACI:
3534 o fixed argument line processing: using $args was broken: It was not
3535 initialized and using args="$args $apc_option" and even args="$args
3536 \"$apc_option\"" fails in the second processing round for any arguments
3537 containing whitespaces. The only correct way is to use the construct
3538 "$@" (but not possible here) or iterate _both_ times over the implicit
3539 argument line (no argument to for-loop) which is what we now use.
3540 o make --with-layout=Apache the default without creating
3541 redundancy (copying the --with-layout block in the argument parsing
3542 loop). We achieve this by using the "$@" construct together with the
3543 `set' command to prepend --with-layout=Apache to the command line in
3544 case --with-layout is not used.
3545 o fixed auto-suffix handling now that config.layout exists.
3546 Paths which are auto-suffixed are marked with a trailing plus sign in
3547 config.layout and every path now can be marked this way (not only the
3548 four paths for which we do it currently). Additionally the suffix is
3549 no longer a static one. Instead it's now `/<target>' where <target> is
3550 the argument of the --target option or per default `httpd'.
3551 o allow also tabs (and only spaces) where we match whitespaces
3552 o various fixes and cleanups related to used shell coding style
3553 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
3554 o trimmed output of --help to fit into 80 columns

3621 identifier, currently "Apache" and "GNU" are pre-defined in the file
3622 config.layout. Custom layouts are possible by using FILE:ID as the
3623 argument where the layout ID is taken from FILE.
3625 The config.layout file consists of <Layout ID>..</Layout> sections
3626 where inside those sections "path_variable: path_value" pairs can be
3627 specified. These lines are converted to path_variable='path_value'.
3629 *) Add a DefaultLanguage directive so that files missing a language
3630 extension (e.g., .fr, .de) can be labelled as being some other

3955 You now must define a BS2000Account name for the server User.
3956 This has fewer security implications than the old approach.
3959 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
3960 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
3961 platform to make the braindead HPUX linker happy. Notice, for the module
3962 DSOs we don't have to use this, because these are loaded manually (and
3963 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968

3974 *) Make PrintPath work generically instead of having one version
3975 strictly for OS/2. [Jim Jagielski, Brian Havard]
3977 *) Fix the recently introduced C header file checking: We now use the C
3978 pre-processor pass only (and no longer the complete compiler pass) to
3979 determine whether a C header file exists or not. Because only this way
3980 we're safe against inter-header dependencies (which caused horrible
3981 portability problems). The only drawback is that we now have a CPP
3982 configuration variable which has to be determined first (we do a similar
3983 approach as GNU Autoconf does here). When all fails the user still has
3984 the possibility to override it manually via APACI or src/Configuration.
3985 As a fallback for the header check itself we can directly check the
3986 existance of the file under /usr/include, too.

4018 platform, because it's only supported under version 4.0 and higher. But
4019 because our GuessOS is still unaware of Digital UNIX versions and the
4020 -msym is just to optimize the DSO statup time a little bit it's safe and
4021 best when we leave it out now. [Ralf S. Engelschall] PR#2969
4023 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
4024 functions: First all three functions no longer fail on strings containing
4025 "%" chars and second ap_log_printf() no longer does a double-formatting
4026 (instead it directly passes through the message to be formatted to the
4027 real internal formatting function). [Ralf S. Engelschall] PR#2941
4029 *) Allow "Include" directives anywhere in the server config
4030 files (but not .htaccess files). [Ken Coar] PR#2727
4032 *) The proxy was refusing to serve CONNECT requests except to
4033 port 443 (https://) and 563 (snews://). The new AllowCONNECT
4034 directive allows the configuration of the ports to which a
4035 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
4037 *) mod_expires will now act on content that is not sent from a file
4038 on disk. Previously it would never add an Expires: header to
4039 any response that did not come from a file on disk; the only
4040 case where it still doesn't (and can't) add one for that type of
4041 content is if you are using a modification date based setting.
4042 [Marc Slemko, Paul Phillips <paulp@go2net.com>]
4044 *) Problems encountered during .htaccess parsing or CGI execution
4045 that lead to a "500 Server Error" condition now provide explanatory
4046 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
4049 *) Add NameWidth keyword to IndexOptions directive so that the

4053 *) Recognize lowercase _and_ uppercase `uname' results under
4054 SCO OpenServer. [David Coelho <drc@ppt.com>]
4056 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
4057 a common problem of (mis-administrated?) IIS servers, make the apache
4058 proxy immune to these errors (and ignore the duplicates, but log
4059 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
4061 *) The <IfModule and <IfDefine block starting directives now only
4062 allow exactly one argument. Previously, the optional negation
4063 character '!' could be separated by whitespace without a syntax
4064 error being reported, albeit defeating the IfModule functionality
4065 (enclosed directives would ALWAYS be executed). By using the
4066 stricter syntax, these hard-to-track errors can be avoided.
4069 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
4070 cause the standalone FancyIndexing directive to logically OR
4071 into any existing IndexOptions settings rather than wiping
4072 them out. [Ken Coar]
4074 *) Changes in ftp proxy: make URL parsing simpler by using the
4076 + Add display of the "current directory" in cases where it's
4077 different from the supplied path (e.g., ftp://user@host/ lives
4078 in /home/user, not in /, therefore clicking on "../" in the
4079 starting directory might send us to /home/).
4080 + When ftp login fails, (esp. when a user name was part of the
4081 URL already), we now return [401 Unauthorized ] to allow the
4082 browser to pop up an authorization dialog. This makes passwords
4083 slightly less visible (they don't appear in the regular log files)
4084 and implements a functionality that other www proxy servers
4088 *) Triggered by the recent "Via:" header changes, the proxy module would
4089 dump core for replies with invalid headers (e.g., duplicate
4090 "HTTP/1.0 200 OK" lines). These errors are now logged and the
4091 core dump is avoided. Also, broken replies are not cached.
4092 [Martin Kraemer] PR#2914
4094 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
4095 plop gmon.out profile data for each child [Doug MacEachern]
4097 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
4098 config.status script to be immune against arguments with whitespaces.
4099 [Yves Arrouye <yves@apple.com>] PR#2866
4101 *) Replace the inlined information grabbing stuff for the configuration
4102 adjustment feature (no --without-confadjust) with calls to a new helper
4103 script `buildinfo.sh' which is both more flexible and already proofed to
4104 be more robust against platform differences. This mainly fixes the
4105 recently occured ``sed: command garbled: ...'' problems.
4106 [Ralf S. Engelschall] PR#2776, PR#2848
4108 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
4109 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
4110 without complains after we recently added the POST feature.
4111 [Ralf S. Engelschall]
4113 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
4114 modules as API functions and we forgot them at the big symbol renaming.

4123 *) Add the ability to do POST requests to the ab benchmarking tool.
4124 [Kurt Sussman <kls@best.com>] PR#2871
4126 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
4127 5 to 10 because there are some users out there who always have 5 to 8
4128 variables in one RewriteRule and had to patch mod_rewrite.h for every
4129 release. So 15 should be now more than enough, even for them. (I never
4130 needed more than 4 in my RewriteRules ;-)
4131 [Ralf S. Engelschall]
4133 *) Make the proxy generate and understand Via: headers
4136 *) Change the proxy to use tables instead of array_headers for
4137 the header lines. [Martin Kraemer]
4139 *) Make sure the config.status file is not overridden when just
4140 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
4142 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
4143 provide a way to trace API changes that add functionality but do
4144 not create a compatibility issue for precompiled modules, etc.
4145 See include/ap_mmn.h for more details. [Randy Terbush]
4147 *) Fix suexec installation under `make install root=xxx' situation.
4148 [Ralf S. Engelschall]
4150 *) Extend the output of the -V switch to include the paths of all
4151 compiled-in configuration files, if they were overridden at
4152 compile time, for least astonishment of the user.
4155 *) When READing a request in ExtendedStatus mode, the "old"
4156 vhost, request and client information is not displayed.
4159 *) STATUS is no longer available. Full status information now
4160 run-time configurable using the ExtendedStatus directive.
4163 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
4164 cpu time attacks) in header parsing. Add ap_overlap_tables(),
4165 a function which can be used to perform bulk update operations
4166 on tables in a more efficient manner. [Dean Gaudet]
4168 *) SECURITY: Added compile-time and configurable limits for
4169 various aspects of reading a client request to avoid some simple
4170 denial of service attacks, including limits on maximum request-line
4171 size (LimitRequestLine), number of header fields (LimitRequestFields),
4172 and size of any one header field (LimitRequestFieldsize). Also added
4173 a configurable directive LimitRequestBody for limiting the size of the
4174 request message body. [Roy Fielding]
4176 *) Make status module aware of DNS and logging states, even if
4177 STATUS not defined. [Jim Jagielski]
4179 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
4181 *) Enhance mod_speling so that CheckSpelling can be used in

4185 ErrorDocument mechanism at runtime [Doug MacEachern]
4187 *) API: new ap_uuencode() function [Doug MacEachern]
4189 *) API: scan_script_header_err_core() now "public" and renamed
4190 ap_scan_script_header_err_core() [Doug MacEachern]
4192 *) The 'status' module will now show the process pid's and their
4193 state even without full STATUS accounting. [Jim Jagielski]
4195 *) Restore the client IP address to the error log messages, this
4196 was lost during the transition from 1.2 to 1.3. Add a new
4197 function ap_log_rerror() which takes a request_rec * and
4198 formats it appropriately. [Dean Gaudet] PR#2661
4200 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
4201 whitespace in input lines -- including within quoted strings.
4203 but leading and trailing whitespace should continue to be
4204 stripped [Martin Kraemer]
4206 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
4207 the ugly use of an env. variable and use command-line args for
4208 alternate $PATH. Make more like advanced 'type's as well.
4211 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
4212 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
4213 <alain.st-denis@ec.gc.ca>] PR#2736
4215 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
4217 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
4218 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
4219 directory was renamed to src/os/os2/ for consistency.
4220 [Brian Havard, Ralf S. Engelschall]
4222 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
4223 files (here modules) against other DSO files (here shared libraries).
4224 This is done by determining a subset of LIBS which can be safely used for
4225 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
4226 disabled for all platforms to avoid problems with this (experimental)
4227 rule. But we provide it now for those people how ran into problems and
4228 want to came out by forcing linking against DSOs.

4231 *) Fix suEXEC start message: Has to be of `notice' level to really get

4245 cause the client to miss the HTTP error response. [Roy Fielding]
4247 *) One more portability fix for APACI shadow tree support: Swap order of awk
4248 and sed in top-level configure script to avoid sed fails on some
4249 platforms (for instance SunOS 4.1.3 and NCR SysV) because of the

4380 TestCompile) instead of defining them manually in conf.h based on less
4381 accurate platform definitions. This way we no longer have to fiddle with
4382 OS-type and/or OS-version identifiers to discover whether a system header
4383 file exists or not. Instead we now directly check for the existence of
4384 those esoteric ones.

4388 *) mod_setenvif (BrowserMatch* and friends) will now match a missing
4389 field with "^$". [Ken Coar]
4391 *) Set the RTLD_GLOBAL dlopen mode parameter to allow dynamically loaded
4392 modules to load their own modules dynamically. This improves mod_perl
4393 and mod_php3 when these modules are loaded dynamically into Apache.
4396 *) Cache a proxied request in the event that the client cancels the
4397 transfer, provided that the configured percentage of the file has
4398 already been transfered. It works for HTTP transfers only. The
4399 new configuration directive is called CacheForceCompletion.

4424 *) The APACI libexecdir was not extended with an "apache/" subdir
4425 if the installation prefix didn't already contain "apache", but
4426 it should be because the DSO files are Apache-specific. Now
4427 libexecdir is treated the same way sysconfdir, datadir, localstatedir

4484 these are treated by Win32 as if they are ".." but are not detected by

4486 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]

4503 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
4504 remove some of the classical hurdles for new users when setting up
4505 Apache. This is done per default because it is useful for the average
4506 user. Package authors can use the --without-confadjust option to disable
4507 these configuration adjustments.
4508 [Ralf S. Engelschall]
4510 *) Added an EXTRA_DEPS configuration parameter which can be used
4511 to add an extra Makefile dependency for the httpd target, for instance
4512 to external third-party libraries, etc.
4513 [Ralf S. Engelschall]
4515 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
4516 as <IfModule>..</IfModule> sections) which can be used to skip or process
4517 contained commands dependend of ``-D PARAMETER'' options on the command
4518 line. This can be used to achieve logical conditions like <IfDefine
4519 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
4520 and thus especially can be used for conditionally loading DSO-based
4521 modules via LoadModule, etc. [Ralf S. Engelschall]

4528 truncated which forced following HTTP headers to be data in the HTTP
4529 reponse. [Ralf S. Engelschall, Charles Fu <ccwf@bacchus.com>]
4532 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
4533 in top-level configure script to avoid sed fails on some platforms (for
4534 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
4535 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
4537 *) Improve performance of directory listings (mod_autoindex) by comparing
4538 integer keys (last-modified and size) as integers rather than converting
4539 them to strings first. Also use a set of explicit byte tests rather
4540 than strcmp() to check for parent directory-ness of an entry. Oh, and
4541 make sure the parent directory (if displayed) is *always* listed first
4542 regardless of the sort key. Overall performance winnage should be good
4543 in CPU time, instruction cache, and memory usage, particularly for large
4544 directories. [Ken Coar]
4546 *) Add a tiny but useful goody to APACI's configure script: The generation
4547 of a config.status script (as GNU Autoconf does) which remembers the used
4548 configure command and hence can be used to restore the configuration by
4549 just re-running this script or for remembering the configuration between
4551 [Ralf S. Engelschall]
4553 *) Add httpd -t (test) option for running configuration syntax tests only.
4554 If something is broken it complains and exits with a return code
4555 non-equal to 0. This can be used manually by the user to check the Apache
4556 configuration after editing and is also automatically used by apachectl
4557 on (graceful) restart command to make sure Apache doesn't die on restarts
4558 because of a configuration which is now broken since the last (re)start.
4559 This way `apachectl restart' can be used inside cronjobs without having
4560 to expect Apache to be falling down. Additionally the httpd -t can be run
4561 via `apachectl configtest'.

4701 spawn_child was obsoleted and moved to compat.h

4705 programs: ap_spawn_child_err() is used and the Win32 case now uses
4706 CreateProcess() instead of a low-level execl() (which caused problems in

4710 *) A few cosmetics and trivial enhancements to APXS to make the
4711 generated Makefile more user friendly. [Ralf S. Engelschall]
4713 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
4714 was updated to use the normal apache error processing, thereby allowing
4715 proxy errors to be treated by ErrorDocument's as well. For this
4716 purpose, a new module-to-core communication variable "error-notes"
4717 was introduced; the proxy (and possibly other modules) communicates
4718 its error text using this variable. Its content is copied to a new
4719 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
4720 The old proxy special error routine ap_proxy_log_uerror()
4721 was replaced by regular ap_log_error() calls, many messages were made

4725 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
4728 *) Transform the configure message "You need root privileges for suEXEC"
4729 from a fatal error into a (more friendly) warning because the building
4730 ("make") of Apache we can allow, of course. Root privileges are needed
4731 only for the installation step ("make install"). So make sure the

4798 of the original copy instead of using the cached copy.
4799 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
4801 *) The Makefiles assumed that DSO files are build via $(LD). This
4802 is broken for two reasons: First we never defined at least LD=ld
4803 somewhere to make sure this works (it was silently assumed that most Make
4804 provide a built-in LD definition - ARGL!) and second using the generic LD
4805 variable is not the truth. Instead a special variable named LD_SHLIB is
4806 reasonable because although "ld" is usually the default, the command for
4807 building DSO files can be "libtool" or even "cc" on some systems.
4808 [Ralf S. Engelschall]
4810 *) Replace the AddVersionPlatform directive with ServerTokens which
4811 provides for more control over the format of the Server:

4820 not retrieved in src/Configure and thus was not useable.

4823 *) Various Makefile consistency cleanups:
4824 - make OSDIR also automatically be relative to src/ like INCDIR
4825 - SUBDIRS is now generated in src/Makefile only and not in
4826 Makefile.config because it is a local define for this location.
4827 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
4828 any Makefile but make sure that at least the "-K inline" is kept in
4830 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
4831 - updated the dependencies theirself
4832 - removed not existing SHLIB variable from "clean" targets
4833 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
4834 already exists and OBJS_PIC are also just plain objects and have not
4835 directly to do with "shared" things. The only difference is that they
4836 contain PIC. So OBJS_PIC is the more canonical name.
4837 - Updated the Makefile-dependency lines for OBJS_PIC
4838 - Removed the Makefile-dependency line in Configure to avoid double
4840 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
4841 of xxx.lo as GNU libtool does with its PIC objects
4842 - reduce local complexity in modules Makefile.tmpl by moving the last
4843 existing target "depend" to the generation section in Configure, too.
4844 - removed the historical $(SPACER) which was used in the past together
4845 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
4846 is no longer needed.
4847 - force the build and run of the gen_xxx programs under main/ as the
4848 first step before building the objects because it looks cleaner

4863 we use ap_pfopen to open these files to handle timeouts.

4866 *) Apache will now log the reason its httpd children exit if they exit
4867 due to an unexpected signal. (It requires a new porting define,

4872 like WIN32. Before, Win32 CGI's could have had sporadic failures
4873 if a chdir call from one thread was made between another chdir call
4874 and a spawn in another thread. So, for now don't chdir for CGI scripts
4875 in WIN32. The current CGI "spec" is unclear as to whether it's
4876 necessary. Long-term fix is to either serialize the chdir/spawn combo
4877 or use WIN32 native calls to spawn a process. This temp fix was
4878 necessary to remove this as a showstopper for 1.3's release.
4881 *) Cleanup the suEXEC support in APACI and make it more safe:
4882 1. Add big fat hint in INSTALL about risks and to read the
4883 htdocs/manual/suexec.html document before using the suexec-related
4885 2. Make sure the user has at least provided one --suexec-xxxx option
4886 (specifies suEXEC parameters) in addition to --enable-suexec option.
4887 If only --enable-suexec is given APACI stops with a hint to INSTALL
4888 and htdocs/manual/suexec.html documents.
4889 3. Provide two additional --suexec-xxxx options to make the suEXEC
4890 configuration complete (especially for package maintainers who else
4891 had to patch the source tree) by providing ways to configure minimal
4892 UID/GID and safe PATH, too.
4893 [Ralf S. Engelschall]
4895 *) Cleanup of the `configure --shadow' process:
4896 - make sure the configure script creates its temporary files in the
4897 shadow tree to avoid conflicts with parallel configure runs
4898 - removed unnecessary option "-r" from "rm" call for Makefiles
4899 - make sure the configure scripts creates the shadow-wrapper Makefile
4900 only when no shadow trees already exists
4901 - make sure "make distclean" removes the shadow-wrapper Makefile but only
4902 when no more shadow trees exists
4903 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
4904 as fast (in the past it needed 70sec, now it runs just 38sec)
4905 - make sure CVS does not complain about the created files
4906 Makefille.<gnutriple> and directories src.<gnutriple>
4907 [Ralf S. Engelschall]
4909 *) Added the ap_add_version_component() API routine and the
4910 AddVersionPlatform core directive. The first allows modules to
4911 declare themselves in the Server response header field value,
4912 augmenting the SERVER_SUBVERSION define in the Configuration file
4913 with run-time settings (more useful in a loadable-module environment).
4914 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
4915 into the server version string. [Ken Coar] PR#2056
4917 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
4920 *) Emit the "Accept-Range" header for the default handler.
4921 [Brian Behlendorf] PR#1464
4923 *) Add a note to httpd.conf-dist that apache will on some systems fail
4924 to start when the Group # is set to a negative or large positive value.
4927 *) Make sure the module execution order is correct even when some modules
4928 are loaded under runtime (`LoadModule') via the DSO mechanism:
4929 1. The list of loaded modules is now a dynamically allocated one
4930 and not the original statically list from modules.c
4931 2. The loaded modules are now correctly setup by LoadModule for
4932 later use by the AddModule command.
4933 3. When the DSO mechanism for modules is used APACI's `install'
4934 target now enables all created `LoadModule' lines per default because
4935 this is both already expected by the user _and_ needed to avoid
4936 confusion with the next point and reduces the Makefile.tmpl complexity
4937 4. When the DSO mechanism for modules is used, APACI's `install'
4938 target now additionally makes sure the module list is reconstructed
4939 via a complete `ClearModuleList+AddModule...' entry.
4940 5. The support tool `apxs' now also makes sure an AddModule command
4941 is added in addition to the LoadModule command.
4942 6. The modules.c generation was extended to now contain two
4943 comments to make sure no one is confused by the confusing terminology
4944 of loading/linking (we use load=link+load & link=activate instead of
4945 the obvious load=activate & link=link :-( )
4946 This way now there is no longer a difference under execution time between
4947 statically and dynamically linked modules.
4948 [Ralf S. Engelschall]
4950 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
4951 Big Symbol Renaming. [Ralf S. Engelschall]
4953 *) Add a comment to mod_example.c showing the format of a FLAG command
4956 *) Standardized the time format in mod_status to match that of other
4957 places in the code (e.g. DATE_GMT). PR#1551
4959 *) Fix handling of %Z in timefmt strings for those platforms with no time
4960 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
4963 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
4964 feature compatible with 'UseCanonicalName off' by changing
4965 r->server->server_hostname to ap_get_server_name(). And I changed some
4966 functions which use r->server->port to use ap_get_server_port() instead,
4967 because if there's no Port directive in the config r->server->port is 0.
4970 *) get/set_module_config are trivial enough to be better off inline. Worth
4971 1.5% performance boost. [Dean Gaudet]
4973 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
4974 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
4977 *) [BS2000 security] BS2000 needs an extra authentication to initialize
4978 the task environment to the unprivileged User id. Otherwise CGI scripts
4979 would have a way to gain super user access. [Martin Kraemer]
4981 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
4982 absolute path, only log base name of logging source as is done
4983 in unix. [Martin Kraemer]
4985 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
4986 the encoding type from the Accept-Encoding header (if it's there)
4987 and use it in the response, as that's probably what it'll be expecting.
4988 [Ronald.Tschalaer@psi.ch]
4990 *) Fix to mod_alias: translate_alias_redir is dealing with
4991 a URI, not a filename, so the check for drive letters for win32
4992 and emx is not necessary. [Dean Gaudet]
4994 *) WIN32: Allow .cmd as an executable extension.

5000 *) Child processes can now "signal" (by exiting with a status
5001 of APEXIT_CHILDFATAL) the parent process to abort and
5002 shutdown the server if the error in the child process was
5003 fatal enough. [Jim Jagielski]
5005 *) mod_autoindex's find_itme() was sensitive to MIME type case.
5006 [Jim Jagielski] PR#2112
5008 *) Make sure the referer_log and agent_log entries in the default httpd.conf
5009 file are also adjusted for the actual relative installation paths.
5010 [Ralf S. Engelschall] PR#2175
5012 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
5014 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
5017 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
5018 Additionally the checks for finding the vendor DSO library were moved
5019 from mod_so.c to Configure because first it needs $PLAT etc. and second
5020 mod_so already uses an abstraction layer and does not fiddle with the
5021 vendor functions itself.
5022 [Jens-Uwe Mager, Ralf S. Engelschall]
5024 *) PORT: Some optimization defines for NetBSD
5025 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
5027 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
5028 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
5030 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
5031 AIX variants should work fine, too. Even AIX 3.x should work). This is
5032 accomplished by using the free DSO emulation code from Jens-Uwe Mager
5033 which we put into a os/unix/os-dso-aix.c file.
5034 [Ralf S. Engelschall]
5036 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
5037 that we should use NET_SIZE_T == int but the include files force size_t.
5038 [Ralf S. Engelschall]
5040 *) Fix two bugs in select() handling in http_main.c.
5043 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
5044 is unset (as it is in situations like timeouts) where it is unclear
5045 whether errno is set or not. [Martin Kraemer]
5047 *) Just having APACI's localstatedir is too general and not enough for most
5048 of the systems. 1.3b6 again required manual APACI patches by package
5049 maintainers from RedHat and FreeBSD because for their filesystem layout a
5050 little bit more flexibility in configuring the paths is needed. Hence we
5051 provide three additional configure options (--runtimedir, --logfiledir,
5052 --proxycachedir) which now can be used for more granular adjustments if
5053 --localstatedir is not enough to fit the particular needs. As a nice
5054 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
5055 [Ralf S. Engelschall]
5057 *) Make the install root for "make install" in APACI's Makefile overrideable
5058 by package authors. This way we are even more friendly to package
5059 maintainers (especially Debian and RedHat) who build for the real prefix
5060 via "configure --prefix=/<real>" but use a different local prefix via
5061 "make root=/tmp/apache install" for rolling the package without bristling
5062 the target location on their system.
5063 [Ralf S. Engelschall]
5065 *) Workaround sed limitations in APACI's configure script by now
5066 substituting in chunks of 50 commands (because for instance HPUX's vendor
5067 sed has a limit of max. 98 commands)
5068 [Ralf S. Engelschall] PR#2136
5070 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
5071 [Ralf S. Engelschall] PR#2140
5073 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
5074 RENAMING process because they are defined as pre-processor macros instead
5075 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
5076 [Ralf S. Engelschall]
5078 *) Workaround braindead AWK's when generating ap_config.h: The split() and
5079 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
5080 [Ralf S. Engelschall] PR#2139
5082 *) Various bugfixes and cleanups for the APACI configure script:
5083 o fix IFS handling for _nested_ situation
5084 o fix Perl interpreter search: take first one found instead of last one
5085 o fix DSO consistency check
5086 o print error messages to stderr instead of stdout
5087 o add install-quiet for --shadow situation to Makefile stub
5088 o reduce complexity by avoiding sed-hacks for rule and module list loops
5089 [Ralf S. Engelschall]
5091 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
5093 *) Make sure the input field separator (IFS) shell variable is explicitly
5094 initialized correctly before _every_ `for' loop and also restored after
5095 the loops. [Ralf S. Engelschall]
5097 *) Make sure that "make install" doesn't overwrite the `mime.types' and
5098 `magic' files from an existing Apache installation. Because people often
5099 customize these for own MIME and content types.
5100 [Ralf S. Engelschall]

5106 [Ralf S. Engelschall] PR#2105
5108 *) Let "configure" clear out the users parameters (provided as shell

5113 *) Provide backward compatibility from some old src/Configuration.tmpl
5114 parameter names to the canonical Autoconf-style shell variable names. For

5137 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
5139 *) If you start apache with the -S command line option it will dump
5140 out the parsed vhost settings. This is useful for folks trying
5141 to figure out what is wrong with their vhost configuration.
5142 (Other dumps may be added in the future.) [Dean Gaudet]
5144 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
5145 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
5148 *) Because /usr/local/apache is the default prefix the ``configure
5149 --compat'' option no longer has to set prefix, again. This way the
5150 --compat option honors a leading --prefix option. [Lars Eilebrecht]
5152 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
5153 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
5154 to avoid "discard const" warnings. [Ralf S. Engelschall]
5156 *) If a specific handler is set for a file yet the request still
5157 ends up being handled by the default handler, log an error
5158 message before handling it. This catches things such as trying
5159 to use SSIs without mod_include enabled. [Marc Slemko]
5161 *) Fix error logging for the startup case where ap_log_error() still uses
5162 stderr as the target. Now the default log level is honored here, too.

5170 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
5172 Changes with Apache 1.3b6
5174 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
5176 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
5177 interface via the similar but proprietary HP/UX shl_xxx-style system
5178 calls. [Ralf S. Engelschall]
5180 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
5181 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
5182 Make. [Ralf S. Engelschall]
5184 *) ++++ THE BIG SYMBOL RENAMING ++++
5185 To avoid symbol clashes with third-party code compiled into the server,
5186 we globally applied the prefix "ap_" to the following classes of
5188 - Apache provided general functions (e.g., ap_cpystrn)
5189 - Public API functions (e.g., palloc, bgets)
5190 - Private functions which we can't make static (because of
5191 cross-object usage) but should be (e.g., new_connection)
5192 For backward source compatibility a new header file named compat.h was
5193 created which provides defines for the old symbol names and can be used
5194 by third-party module authors.
5197 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
5198 problem under SVR4 is that there is no command flag to force the linker
5199 to export the global symbols of the httpd executable therewith they are
5200 available to the DSO's. Instead of problematic hacks like creating a
5201 dummy.so file (containing dummy references to all global symbols) the
5202 httpd binary is linked against, we use a clean trick stolen from Perl 5:
5203 Placing the Apache core code itself into a DSO library named libhttpd.so.
5204 This way the global symbols _HAVE_ to be exported and thus are available
5205 to any manually loaded DSO's under runtime. To reduce the impact to the
5206 user to null we go even further and create a stub httpd executable which
5207 automatically keeps track of the DSO library loading itself and thus
5208 hides the complete mechanism from the user. Although the generation of
5209 this DSO library is automatically triggered for platforms which
5210 essentially need it (mostly all SVR4-derivates) it can be also enabled
5211 manually via the Rule SHARED_CORE. This can be interesting in the future
5212 where we perhaps exploit this libhttpd.so mechanism for providing nifty
5213 features like graceful upgrades, or whatever.
5214 [Ralf S. Engelschall, Martin Kraemer]
5216 *) Build the libraries before building the rest of the tools. [Ben Hyde]
5218 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
5219 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
5220 conventions while "clean" removes only stuff created by "all" targets,
5221 "distclean" additionally removes the stuff from the configuration
5222 process. This way "make distclean" (hence the name) provides a fresh
5223 source tree as it was for distribution.
5224 [Ralf S. Engelschall]
5226 *) Allow top-level (APACI) Makefile to break on build errors
5227 the same way the src/ subtree Makefiles breaks on them by replacing the
5228 initial APACI sed-subdir-display-kludge with a more clean
5229 variable-passing-solution: variable SDP can optionally hold the subdir
5230 prefix which is consistently used for displaying the subdir movement.
5231 This way even the top-level Makefile can stop correctly on errors as the
5232 user expects. [Ralf S. Engelschall]
5234 *) Fixed ordering of argument checks for RewriteBase directive.
5235 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
5237 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
5238 indicating that a module is being compiled for dynamic loading. Also
5239 remove #define IS_MODULE from modules and add SHARED_MODULE define
5240 to the mak/dsp files. [Alexei Kosut]
5242 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
5243 since we are now logging APLOG_WARNING by default. [Roy Fielding]
5245 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
5247 *) Add documentation file and src/Configuration.tmpl entry for the
5248 experimental mod_mmap_static module. Because although it is and marked as
5249 an experimental one it is distributed and thus should be documented and
5250 prepared for configuration the same way as all others modules.
5251 [Ralf S. Engelschall]
5253 *) Add query (-q) option to apxs support tool to be able to manually query
5254 specific settings from apxs. This is needed for instance when you
5255 manually want to access Apache's header files and you need to assemble
5256 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
5257 [Ralf S. Engelschall]
5259 *) Now src/Configure uses a fallback strategy for the shared object support
5260 on platforms where no explicit information is available: If a Perl
5261 installation exists we ask it about its shared object support and if it's
5262 the dlopen-style one we shamelessly guess the compiler and linker flags
5263 for creating shared objects from Perls knowledge. Of course, the user is
5264 warning about what we are doing and informed that he should send us
5265 the guessed flags when they work. [Ralf S. Engelschall]
5267 *) Provide APACI --without-support option to be able to disable the build
5268 and installation of the support tools from the src/support/ area.
5269 Although its useful to have these installed per default we should provide
5270 a way to compile and install without them for backward-compatibility.
5271 [Ralf S. Engelschall]
5273 *) Add of the new APache eXtenSion (apxs) support tool for building and
5274 installing modules into an _already installed_ Apache package through the
5275 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
5276 this approach actually doesn't need the Apache source tree. The
5277 (APACI-installed) server package is enough, because this now includes the
5278 Apache C header files (PREFIX/include) and the new APXS tool
5279 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
5280 module authors to build their Apache modules _OUTSIDE_ the Apache source
5281 tree while avoiding them to fiddle around with the totally platform
5282 dependend way of compiling DSO files. The tool supports all ranges of
5283 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
5284 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
5285 on-the-fly generate a minimalistic Makefile and sample module for the
5286 first step to provide both a quick success event and to demonstrate the
5287 APXS mechanism to module authors. [Ralf S. Engelschall]
5289 *) Fix core dumps in use of CONNECT in proxy.
5290 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
5292 *) Modify the log directives in httpd.conf-dist files to use CustomLog
5293 so that users have examples of how CustomLog can be used.
5296 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
5297 the Apache distribution tree. Until Apache 1.3 there was no real
5298 out-of-the-box batch-capable build and installation procedure for the
5299 complete Apache package. This is now provided by a top-level "configure"
5300 script and a corresponding top-level "Makefile.tmpl" file. The goal is
5301 to provide a GNU Autoconf-style frontend which is capable to both drive
5302 the old src/Configure stuff in batch and additionally installs the
5303 package with a GNU-conforming directory layout. Any options from the old
5304 configuration scheme are available plus a lot of new options for flexibly
5305 customizing Apache. [Ralf S. Engelschall]
5307 *) The floating point ap_snprintf code wasn't threadsafe.

5317 Configure knows which CC we are using. [Jim Jagielski]
5319 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
5320 was defined in a parent directory. [Lars Eilebrecht]
5322 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
5323 a generic printf-style routine that can call arbitrary output
5324 routines. Use this to replace http_bprintf.c. Add new routines
5325 psprintf(), pvsprintf() which allocate the exact amount of memory
5326 required for a string from a pool. Use psprintf() to clean up
5327 various bits of code which used ap_snprintf()/pstrdup().
5330 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
5331 ap_snprintf() has different semantics and formatting codes than
5332 snprintf(). [Dean Gaudet]
5334 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
5335 is necessary on at least Solaris where the /etc/rc?.d scripts
5336 are run with these signals ignored, and "SIG_IGN" settings are
5337 maintained across exec().

5352 be a signed bitfield. So mark a few bitfields as signed to
5353 ensure correct code. [Dean Gaudet]

5358 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
5361 *) After a SIGHUP the listening sockets in the parent weren't
5362 properly marked for closure on fork().
5363 [Jürgen Keil <jk@tools.de>] PR#2000
5365 *) Allow %2F in two situations: 1) it is in the query part of the URI,
5366 therefore not exposed to %2F -> '/' translations and 2) the request
5367 is a proxy request, so we're not dealing with a local resource anyway.
5368 Without this, the proxy would fail to work for any URL's with
5369 %2f in them (occurs quite often in
5370 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
5372 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
5374 *) Make the shared object compilation command more portable by avoiding
5375 the direct combination of `-c' & `-o' which is not honored by some
5376 compilers like UnixWare's cc. [Ralf S. Engelschall]
5378 *) WIN32: the proxy was creating filenames missing the last four

5383 *) Now mod_proxy uses the response string (in addition to the response status
5384 code) from the already used FTP SIZE command to setup the Content-Length
5385 header if available. [Ralf S. Engelschall] PR#1183
5387 *) Reanimated the (still undocumented) proxy receive buffer size directive:
5388 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
5389 name was really too generic, added documentation for this directive to
5390 the mod_proxy.html and corrected the hyperlink to it in the
5391 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348

5394 faster [Martin Kraemer]
5396 *) Make Configure die when you give it an unknown command switch.
5399 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
5400 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
5401 and per default compiled support programs have manual pages - just to
5402 document our stuff a little bit more and to be able to do really
5403 Unix-like installations ;-) [Ralf S. Engelschall]
5405 *) Major cleanups to the Configure script to make it and its generated
5406 Makefiles again readable and maintainable: add SRCDIR option, removed
5407 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
5408 generated sections, consequently added Makefile headers with inheritance
5409 information, added subdir movement messages for easier following where
5410 the build process currently stays (more verbose then standard Make, less
5411 verbose than GNU make), same style to comments in the Configure script,
5412 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
5414 *) Add the new ApacheBench program "ab" to src/support/: This is derived
5415 from the ZeusBench benchmarking program and can be used to determine the
5416 response performance of an Apache installation. This version is
5417 officially licensed with Zeus Technology, Ltd. See the license agreement

5419 [Ralf S. Engelschall]
5421 *) API: Various core functions that are definately not part of the API
5422 have been made static, and a few have been marked API_EXPORT. Still
5423 more have been marked CORE_EXPORT and are not intended for general
5424 use by modules. [Doug MacEachern, Dean Gaudet]
5426 *) mod_proxy was not clearing the Proxy-Connection header from
5427 requests; now it does. This did not violate any spec, however
5428 causes poor interactions when you are talking to remote proxies.

5437 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
5439 *) Clean up some undocumented behavior of mod_setenvif related to
5440 "merging" two SetEnvIf directives when they match the same header
5441 and regex. Document that mod_setenvif will perform comparisons in
5442 the order they appear in the config file. Optimize mod_setenvif by
5443 doing more work at config time rather than at runtime.
5446 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
5447 to allow for modules to overrule them and to reduce redefinition
5448 warnings [Jim Jagielski]
5450 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
5453 *) Making the hard-coded cross-module function call mime_find_ct() (from
5454 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
5455 checking is really called even for proxy requests except for URLs with
5456 HTTP schemes (because there we can optimize by not running the type
5457 checking hooks due to the fact that the proxy gets the MIME Content-type
5458 from the remote host later). This change cleans up mod_mime by removing
5459 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
5460 especially unbundles mod_proxy and mod_mime. This way they both now can
5461 be compiled as shared objects and are no longer tied together.
5462 [Ralf S. Engelschall]
5464 *) util.c cleanup and speedup. [Dean Gaudet]
5466 *) API: Clarification, pstrndup() will always copy n bytes of the source
5467 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
5469 *) Mark module command_rec and handler_rec structures const so that they
5470 end up in the read-only data section (and are friendlier to systems
5471 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
5473 *) Add check to the "Port" directive to make sure the specified
5474 port is in the appropriate range. [Ben Hyde]
5476 *) Performance improvements to invoke_handler().
5477 [Dmitry Khrustalev <dima@bog.msu.su>]
5479 *) Added support for building shared objects even for library-style modules
5480 (which are built from more than one object file). This now provides the
5481 ability to build mod_proxy as a shared object module. Additionally
5482 modules like mod_example are now also supported for shared object
5483 building because the generated Makefiles now no longer assume there is at
5484 least one statically linked module. [Ralf S. Engelschall]
5486 *) API: Clarify usage of content_type, handler, content_encoding,
5487 content_language and content_languages fields in request_rec. They
5488 must always be lowercased; and the strings pointed to shouldn't
5489 be modified (you must copy them to modify them). Fix a few bugs
5490 related to this. [Dean Gaudet]
5492 *) API: Clarification: except for RAW_ARGS, all command handlers can
5493 treat the char * parameters as permanent, and modifiable. There
5494 is no need to pstrdup() them. Clean up some needless pstrdup().
5497 *) Now mod_so keeps track of which module shared objects with which names
5498 are loaded and thus avoids multiple loading and unloading and irritating
5499 error_log messages. [Ralf S. Engelschall]
5501 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
5502 environment variable in the apache core. But that tweaking interferes
5503 with mod_setenv. So don't tweak if the user has specified an explicit
5504 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
5506 *) rputs() did not calculate r->sent_bodyct properly.
5507 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
5509 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
5510 name, or left unset if this value is unavailable. Apache was setting
5511 it to the IP address when unavailable.
5512 [Tony Finch <fanf@demon.net>] PR#1925
5514 *) Various improvements to the configuration and build support for compiling
5515 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
5516 OSF1 support with GCC and vendor compilers was added. This way shared
5517 object support is now provided out-of-the-box for FreeBSD, Linux,
5518 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
5519 [Ralf S. Engelschall]
5521 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
5522 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
5523 and USE_OS2_SCOREBOARD. [Dean Gaudet]
5525 *) Fix one more special locking problem for RewriteMap programs in
5526 mod_rewrite: According to the documentation of flock(), "Locks are on
5527 files, not file descriptors. That is, file descriptors duplicated
5528 through dup(2) or fork(2) do not result in multiple instances of a lock,
5529 but rather multiple references to a single lock. If a process holding a
5530 lock on a file forks and the child explicitly unlocks the file, the
5531 parent will lose its lock.". To overcome this we have to make sure the
5532 RewriteLock file is opened _AFTER_ the childs were spawned which is now
5533 the case by opening it in the child_init instead of the module_init API
5534 hook. [Ralf S. Engelschall] PR#1029
5536 *) Change to Location and LocationMatch semantics. LocationMatch no
5537 longer lets a single slash match multiple adjacent slashes in the
5538 URL. This change is for consistency with RewriteRule and
5539 AliasMatch. Multiple slashes have meaning in URLs that they do
5540 not have in (some) filesystems. Location on the other hand can
5541 be considered a shorthand for a more complicated regex, and it
5542 does match multiple slashes with a single slash -- which is
5543 also consistent with the Alias directive.
5544 [Dean Gaudet] related PR#1440
5546 *) Fix bug with mod_mime_magic causing certain files, including files
5547 of length 0, to result in no response from the server.
5550 *) The Configure script now generates src/include/ap_config.h which
5551 contains the set of defines used when Apache is compiled on a platform.
5552 This file can then be included by external modules before including
5553 any Apache header files in case they are being built separately from
5554 Apache. Along with this change, a couple of minor changes were
5555 made to make Apache's #defines coexist peacefully with any autoconf
5556 defines an external module might have. [Rasmus Lerdorf]
5558 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
5559 but without any RewriteXXXXX directives. Here mod_rewrite is given no
5560 chance by the API to initialize its per-server configuration and thus
5561 receives the wrong one from the main server. This is now avoided by
5562 remembering the server together with the config structure while
5563 configuring and later assuming there is no config when we see a
5564 difference between the remembered server and the one calling us.
5565 [Ralf S. Engelschall] PR#1790
5567 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
5568 is automatically disabled under configure time when the dbm_xxx functions
5569 are not available. Second, two heavy source code errors in the DBM
5570 support code were fixed. This makes DBM RewriteMap's usable again after
5571 a long time of brokenness. [Ralf S. Engelschall] PR#1696
5573 *) Now all configuration files support Unix-style line-continuation via
5574 the trailing backslash ("\") character. This enables us to write down
5575 complex or just very long directives in a more readable way. The
5576 backslash character has to be really the last character before the
5577 newline and it has not been prefixed by another (escaping) backslash.

5583 *) To deal with modules being compiled and [dynamically] linked
5584 at a different time from the core, the SERVER_VERSION and
5585 SERVER_BUILT symbols have been abstracted through the new
5586 API routines apapi_get_server_version() and apapi_get_server_built().
5589 *) WIN32: Preserve trailing slash in canonical path (and hence
5590 in PATH_INFO). [Paul Sutton, Ben Laurie]
5592 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
5593 depending on the rev of Solaris and what mixture of modules
5594 are in use. So it has been disabled, and Solaris is back to
5595 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
5596 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
5597 up static content only servers. Or it may fail unpredictably.
5598 [Dean Gaudet] PR#1779, 1854, 1904
5600 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
5603 *) API: Rewrite of absoluteURI handling, and in particular how
5604 absoluteURIs match vhosts. Unless a request is a proxy request, a
5605 "http://host" url is treated as if a similar "Host:" header had been
5606 supplied. This change was made to support future HTTP/1.x protocols
5607 which may require clients to send absoluteURIs for all requests.
5609 In order to achieve this change subtle changes were made to the API. In a
5610 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
5611 that the unmodified uri can be retrieved easily. r->proxyreq is not set
5612 by the core, modules must set it during the post_read_request or
5613 translate_names phase.
5615 Plus changes to the virtualhost test suite for absoluteURI testing.
5617 This fixes several bugs with the proxy proxying requests to vhosts
5618 managed by the same httpd.
5621 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
5622 code from mod_rewrite. The vhost matching is now performed by a
5623 globally available function matches_request_vhost(). [Dean Gaudet]

5639 *) API: A new source module main/util_uri.c; It contains a routine
5640 parse_uri_components() and friends which breaks a URI into its component
5641 parts. These parts are stored in a uri_components structure called
5642 parsed_uri within each request_rec, and are available to all modules.
5643 Additionally, an unparse routine is supplied which re-assembles the URI
5644 components back to an URI, optionally hiding the username:password@ part
5645 from ftp proxy requests, and other useful routines. Within the structure,
5646 you find on a ready-for-use basis:
5647 scheme; /* scheme ("http"/"ftp"/...) */
5648 hostinfo; /* combined [user[:password]@]host[:port] */
5649 user; /* user name, as in http://user:passwd@host:port/ */
5650 password; /* password, as in http://user:passwd@host:port/ */
5651 hostname; /* hostname from URI (or from Host: header) */
5652 port_str; /* port string (integer representation is in "port") */
5653 path; /* the request path (or "/" if only scheme://host was given) */
5654 query; /* Everything after a '?' in the path, if present */
5655 fragment; /* Trailing "#fragment" string, if present */
5656 This is meant to serve as the platform for *BIG* savings in
5657 code complexity for the proxy module (and maybe the vhost logic).
5660 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
5661 ${map:key}) available for all location where a string is created in
5662 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
5663 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
5664 possible expansions are consequently usable at all string creation
5665 locations. [Ralf S. Engelschall]
5667 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
5668 and not 1) and the per-virtual-server merging of directives. Now all
5669 directives except `RewriteEngine' and `RewriteOption' are either
5670 completely overridden (default) or completely inherited (when
5671 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

5680 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
5681 (like SunOS and FreeBSD) which don't accept the locking of pipes
5682 directly. A new directive RewriteLock is introduced which can be used to
5683 setup a separate locking file which then is used for synchronization.

5699 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
5701 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
5702 type but with a special post-processing for the looked-up value: It
5703 parses it into alternatives according to `|' chars and then only one
5704 particular alternative is chosen randomly (this is an essential
5705 functionality needed for balancing between backend-servers when using
5706 Apache as a Reverse Proxy. The looked up value here is a list of
5707 servers). Second, `int' with the built-in maps named `tolower' and
5708 `toupper' which can be used to map URL parts to a fixed case (this is an
5709 essential feature to fix the case of server names when doing mass
5710 virtual-hosting with the help of mod_rewrite instead of using
5711 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
5712 Jay Soffian <jay@cimedia.com>] PR#1631
5714 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
5715 This directive lets Apache adjust the URL in Location-headers on HTTP
5716 redirect responses sent by the remote server. This way the virtually
5717 mapped area is no longer left on redirects and thus by-passed which is
5718 especially essential when running Apache as a reverse proxy.

5846 *) Minor cleanups to r->finfo handling in some modules.
5849 *) Abstract read()/write() to ap_read()/ap_write().
5850 Makes it easier to add other types of IO code such as SFIO.
5853 *) API: Generalize default_port manipulations to make support of
5854 different protocols easier. [Ben Laurie, Randy Terbush]
5856 *) There are many cases where users do not want Apache to form

5864 PR#315, 459, 485, 1433
5866 *) Yet another rearrangement of the source tree.. now all the common
5867 header files are in the src/include directory. The -Imain -Iap
5868 references in Makefiles have been changed to the simpler -Iinclude
5869 instead. In addition to simplifying the build a little bit, this
5870 also makes it clear when a module is referencing something in a
5871 other than kosher manner (e.g., the proxy including mod_mime.h).
5872 Module-private header files (the proxy, mod_mime, the regex library,
5873 and mod_rewrite) have not been moved to src/include; nor have
5874 the OS-abstraction files. [Ken Coar]
5876 *) Fix a bug where r->hostname didn't have the :port stripped
5877 from it. [Dean Gaudet]
5879 *) Tweaked the headers_out table size, and the subprocess_env
5880 table size guess in rename_original_environment(). Added
5881 MAKE_TABLE_PROFILE which can help discover make_table()
5882 calls that use too small an initial guess, see alloc.c.
5885 *) Options and AllowOverride weren't properly merging in the main
5886 server setting inside vhosts (only an issue when you have no
5887 <Directory> or other section containing an Options that affects
5888 a request). Options +foo or -foo in the main_server wouldn't
5889 affect the main_server's lookup defaults. [Dean Gaudet]
5891 *) Variable 'cwd' was being used pointlessly before being set.
5894 *) r->allowed handling cleaned up in the standard modules.
5897 *) Some case-sensitivity issues cleaned up to be consistent with
5898 RFC2068. [Dean Gaudet]
5900 *) SIGURG doesn't exist everywhere.
5901 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
5903 *) mod_unique_id was erroneously generating a second unique id when
5904 an internal redirect occured. Such redirects occur, for example,
5905 when processing a DirectoryIndex match. [Dean Gaudet]
5907 *) API: table_add, table_merge, and table_set include implicit pstrdup()
5908 of the key and value. But in many cases this is not required
5909 because the key/value is a constant, or the value has been built
5910 by pstrcat() or other similar means. New routines table_addn,
5911 table_mergen, and table_setn have been added to the API, these
5912 routines do not pstrdup() their arguments. The core code and
5913 standard modules were changed to take advantage of these routines.
5914 The resulting server is up to 20% faster in some situations.
5916 Note that it is easy to get code subtly wrong if you pass a key/value
5917 which is in a pool other than the pool of the table. The only
5918 safe thing to do is to pass key/values which are in the pool of
5919 the table, or in one of the ancestors of the pool of the table.
5920 i.e. if the table is part of a subrequest, a value from the main
5921 request's pool is OK since the subrequest pool is a sub_pool of the
5922 main request's pool (and therefore has a lifespan at most as long as
5923 the main pool). There is debugging code which can detect improper
5924 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.

5927 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
5928 which don't exist on disk more gracefully; handles vhosts properly.
5929 Update documentation to reflect the code -- if there's no
5930 MimeMagicFile directive then the module is not enabled.
5933 *) PORT: Some older *nix dialects cannot automatically start scripts
5934 which begin with a #! interpreter line (the shell starts the scripts
5935 appropriately on these platforms). Apache now supports starting of
5936 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.

5940 *) API: "typedef array_header table" removed from alloc.h, folks should
5941 have been writing to use table as if it were an opaque type, but even
5942 some standard modules got this wrong. By changing the definition
5943 to "typedef struct table table" module authors will receive compile
5944 time warnings that they're doing the wrong thing. This change
5945 facilitates future changes with more sophisticated table
5946 structures. Specifically, module authors should be using table_elts()
5947 to get access to an array_header * for the table. [Dean Gaudet]
5949 *) API: Renamed new_connection() to avoid namespace collision with LDAP
5950 library routines. [Ken Coar, Rasmus Lerdorf]
5952 *) WIN32: mod_speling is now available on the Win32 platform.
5955 *) For clarity the following compile time definition was changed:
5957 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
5959 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
5960 and not be a general notice that the OS has mmap(). Now the
5961 HAVE_MMAP/SHMGET #defines strictly are informational that the
5962 OS has that method of shared memory; the type to use for
5963 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
5964 and USE_SHMGET_SCOREBOARD). This allows outside modules to
5965 determine if shared memory is available and allows Apache
5966 to determine the best method to use for the scoreboard.
5969 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
5970 as do various earlier versions. It should be safe on all versions.

5995 The choice of flock vs. fcntl was made based on timings which showed that
5996 even on non-NFS, non-exported filesystems fcntl() was an order of
5997 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
5998 that single socket users will see no difference. [Dean Gaudet] PR#467

6374 *) OS/2 Port updated; it should be possible to build OS/2 from the same
6375 sources as Unix now. [Brian Havard <brianh@kheldar.apana.org.au>]
6377 *) Fix a year formatting bug in mod_usertrack.

6387 should work, it should work on WIN32, and a few resource
6388 leaks and abort conditions are fixed.
6389 [Dean Gaudet] PR#1205
6391 *) PORT: On AIX 1.x files can't be named '@', fix the proxy cache

6448 *) PORT: All SVR4 systems now use NET_SIZE_T = size_t, and
6449 use USE_SHMGET_SCOREBOARD.
6452 *) Various improvements in detecting config file errors (missing closing
6453 directives for <Directory>, <Files> etc. blocks, prohibiting global
6454 server settings in <VirtualHost> blocks, flagging unhandled multiple
6455 arguments to <Directory>, <Files> etc.)

6459 variable to provide this one to suexec'd CGIs, too.
6460 [M.D.Parker <mdpc@netcom.com>] PR#1284
6462 *) New support tool: src/support/split-logfile, a sample Perl script which
6463 splits up a combined access log into separate files based on the
6464 name of the virtual host (listed first in the log records by "%v").
6467 Changes with Apache 1.3b2 (there is no 1.3b1)
6469 *) TestCompile was not passing $LIBS [Dean Gaudet]
6471 *) Makefile.tmpl was not using $CFLAGS in the link phase.
6474 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
6475 rudimentary memory debugger which can be used on live servers with
6476 low impact -- it sets all allocated and freed memory bytes to 0xa5.
6477 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
6478 and free() for each object. This is far more expensive and should
6479 only be used for testing with tools such as Electric Fence and
6480 Purify. See main/alloc.c for more details. [Dean Gaudet]
6482 *) Configure uses a sh trap and didn't set its exitcode properly.
6483 [Dean Gaudet] PR#1159
6485 *) Yet another vhost revamp. Add the NameVirtualHost directive which
6486 explicitly lists the ip:port pairs that are to be used for name-vhosts.
6487 From a given ip:port, regardless what the Host: header is, you can
6488 only reach the vhosts defined on that ip:port. The precedence of
6489 vhosts was reversed to match other precedences in the config --
6490 the earlier vhosts override the later vhosts. All vhost matching was
6491 moved into http_vhost.[ch]. [Dean Gaudet]
6493 *) ap_inline can be used to force inlining. GNUC __attribute__() can
6494 be used for whatever reason is appropriate (i.e. format() warnings
6495 for printf style functions). Both are enabled only with
6496 gcc >= 2.7.x (so that we have fewer support issues with older
6497 versions). [Dean Gaudet]
6499 *) Fix support for Proxy Authentication (we were testing the response
6500 status too early). [Marc Slemko]
6502 *) CoreDumpDirectory directive directs where the core file is
6503 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
6504 received. [Marc Slemko, Dean Gaudet]
6506 *) PORT: Support for Atari MINT.
6507 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
6509 *) When booting, apache will now detach itself from stdin, stdout,
6510 and stderr. stderr will not be detached until after the config
6511 files have been read so you will be able to see initial error
6512 messages. After that all errors are logged in the error_log.
6513 This makes it more convenient to start apache via rsh, ssh,
6514 or crontabs. [Dean Gaudet] PR#523
6516 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
6517 Also removed the auto-generated link to www.apache.org that was the
6518 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
6520 *) send_fb would not detect aborted connections in some situations.
6523 *) mod_include would use uninitialized data when parsing certain
6524 expressions involving && and ||. [Brian Slesinsky] PR#1139
6526 *) mod_imap should only handle GET methods. [Jay Bloodworth]
6528 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
6530 *) mod_autoindex improperly counted &escapes; as more than one
6531 character in the description. It also improperly truncated
6532 descriptions that were exactly the maximum length.
6535 *) RedirectMatch was not properly escaping the result (PR#1155). Also
6536 "RedirectMatch /advertiser/(.*) $1" is now permitted.
6539 *) mod_include now uses symbolic names to check for request success
6540 and return HTTP errors, and correctly handles all types of
6541 redirections (previously it only did temporary redirect correctly).
6542 [Ken Coar, Roy Fielding]
6544 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
6545 r->filename. Since those two are meant to be in sync with each other
6546 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
6548 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
6549 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]
6551 *) Inetd mode (which is buggy) uses timeouts without having setup the
6552 jmpbuffer. [Dean Gaudet] PR#1064
6554 *) Work around problem under Linux where a child will start looping
6555 reporting a select error over and over.
6556 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
6558 *) Fixed error in proxy_util.c when looping through multiple host IP
6559 addresses. [Lars Eilebrecht] PR#974
6561 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
6562 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
6563 bytes before writing, but it will never split a log entry across a
6564 buffer boundary. [Dean Gaudet]
6566 *) API: the short_score record has been split into two pieces, one which
6567 the parent writes on, and one which the child writes on. As part of
6568 this change the get_scoreboard_info() function was removed, and
6569 scoreboard_image was exported. This change fixes a race condition
6570 in file based scoreboard systems, and speeds up changes involving the
6571 scoreboard in earlier 1.3 development. [Dean Gaudet]
6573 *) API: New register_other_child() API (see http_main.h) which allows
6574 modules to register children with the parent for maintenance. It
6575 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
6577 *) API: New piped_log API (see http_log.h) which implements piped logs,
6578 and will use register_other_child to implement reliable piped logs
6579 when it is available. The reliable piped logs part can be disabled
6580 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
6581 logs is only available on Unix. [Dean Gaudet]
6583 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
6584 meets_conditions(). This allows conditional HTTP selection to be
6585 handled separately from the storing of the header fields, and provides
6586 the ability for CGIs to set their own ETags for conditional checking.
6587 [Ken Coar, Roy Fielding] PR#895
6589 *) Changes to mod_log_config to allow naming of format strings.
6590 Format nicknames are defined with "LogFormat fmt nickname", and can
6591 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
6594 *) New module, "mod_speling", which can help find files even when
6595 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
6597 *) API: New function child_terminate() triggers the child process to
6598 exit, while allowing the child finish what it needs to for the
6599 current request first.
6600 [Doug MacEachern, Alexei Kosut]
6602 *) Windows now defaults to using full status reports with mod_status.
6603 [Alexei Kosut] PR #1094
6605 *) *Really* disable all mod_rewrite operations if the engine is off.
6606 Some things (like RewriteMaps) were checked/performed even if they
6607 weren't supposed to be. [Ken Coar] PR #991
6609 *) Implement a new timer scheme which eliminates the need to call alarm() all
6610 the time. Instead a counter in the scoreboard for each child is used to
6611 show when the child has made forward progress. The parent samples this
6612 counter every scoreboard maintenance cycle, and issues SIGALRM if no
6613 progress has been made in the timeout period. This reduces the static
6614 request best-case syscall count to 22 from 29. This scheme is only
6615 used by systems with memory-based scoreboards. [Dean Gaudet]
6617 *) The proxy now properly handles CONNECT requests which are sent
6618 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
6620 *) A script called apachectl has been added to the support
6621 directory. This script allows you to do things such as
6622 "apachectl start" and "apachectl restart" from the command
6625 *) Modules and core routines are now put into libraries, which
6626 simplifies the link line tremendously (among other advantages).
6629 *) Some of the MD5 names defined in Apache have been renamed to have
6630 an `ap_' prefix to avoid conflicts with routines supplied by
6631 external libraries. [Ken Coar]
6633 *) Removal of mod_auth_msql.c from the distribution. There are many
6634 other options for databases today. Rather than offer one option,
6635 offer none at this time. mod_auth_msql and other SQL database
6636 authentication modules can be found at the Apache Module Registry.
6637 http://modules.apache.org/ It would be nice to offer a generic
6638 mod_auth_sql option in the near future.
6640 *) PORT: BeOS support added [Alexei Kosut]
6642 *) Configure no longer accepts the -make option, since it creates
6643 Makefile on the fly based on Makefile.tmpl and Configuration.
6645 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
6646 of forcibly killing off all its processes and exiting without
6647 cleaning up. [Alexei Kosut]
6649 *) API: A new field in the request_rec, r->mtime, has been added to
6650 avoid gratuitous parsing of date strings. It is intended to hold
6651 the last-modified date of the resource (if applicable). An
6652 update_mtime() routine has also been added to advance it if
6653 appropriate. [Roy Fielding, Ken Coar]
6655 *) SECURITY: If a htaccess file can not be read due to bad permissions,
6656 deny access to the directory with a HTTP_FORBIDDEN. The previous
6657 behavior was to ignore the htaccess file if it could not be read.
6658 This change may make some setups with unreadable htaccess files
6659 stop working. [Marc Slemko] PR#817
6661 *) Add aplog_error() providing a mechanism to define levels of
6662 verbosity to the server error logging. This addition also provides
6663 the ability to log errors using syslogd. Error logging is configurable
6664 on a per-server basis using the LogLevel directive. Conversion
6665 of log_*() in progress. [Randy Terbush]
6667 *) Further enhance aplog_error() to not log filename, line number, and
6668 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
6670 *) WIN32: Canonicalise filenames under Win32. Short filenames are
6671 converted to long ones. Backslashes are converted to forward
6672 slashes. Case is converted to lower. Parts of URLs that do not
6673 correspond to files are left completely alone. [Ben Laurie]
6675 *) PORT: 2 new OSs added to the list of ports:
6676 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
6677 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
6679 *) Add the server version (SERVER_VERSION macro) to the "server
6680 configured and running" entry in the error_log. Also build an
6681 object file at link-time that contains the current time
6682 (SERVER_BUILT global const char[]), and include that in the
6685 *) Set r->headers_out when sending responses from the proxy.
6686 This fixes things such as the logging of headers sent from
6687 the proxy. [Marc Slemko] PR#659
6689 *) support/httpd_monitor is no longer distributed because the
6690 scoreboard should not be file based if at all possible. Use
6691 mod_status to see current server snapshot.
6693 *) (set_file_slot): New function, allowing auth directives to be
6694 independent of the server root, so the server documents can be
6695 moved to a different directory or machine more easily.
6696 [David J. MacKenzie]
6698 *) If no TransferLog is given explicitly, decline
6699 to log. This supports coexistence with other logging modules,
6700 such as the custom one that UUNET uses. [David J. MacKenzie]
6702 *) Check for titles in server-parsed HTML files.
6703 Ignore leading newlines and returns in titles. The old behavior
6704 of replacing a newline after <title> with a space causes the
6705 title to be misaligned in the listing. [David J. MacKenzie]
6707 *) Change mod_cern_meta to be configurable on a per-directory basis.
6708 [David J. MacKenzie]
6710 *) Add 'Include' directive to allow inclusion of configuration
6711 files within configuration files. [Randy Terbush]
6713 *) Proxy errors on connect() are logged to the error_log (nothing
6714 new); now they include the IP address and port that failed
6715 (*that's* new). [Ken Coar, Marc Slemko] PR#352
6717 *) Various architectures now define USE_MMAP_FILES which causes
6718 the server to use mmap() for static files. There are two
6719 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
6720 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
6721 number of bytes written in one cycle from a single mmap()d object,
6722 default 32768). [Dean Gaudet]
6724 *) API: Added post_read_request API phase which is run right after reading
6725 the request from a client, or right after an internal redirect. It is
6726 useful for modules setting environment variables that depend only on
6727 the headers/contents of the request. It does not run during subrequests
6728 because subrequests inherit pretty much everything from the main
6729 request. [Dean Gaudet]
6731 *) Added mod_unique_id which is used to generate a unique identifier for
6732 each hit, available in the environment variable UNIQUE_ID.
6735 *) init_modules is now called after the error logs have been opened. This
6736 allows modules to emit information messages into the error logs.
6739 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
6740 information for case where proxy module is not available. [Marc Slemko]
6742 *) PORT: Apache has need for mutexes to serialize its children around
6743 accept. In prior versions either fcntl file locking or flock file
6744 locking were used. The method is chosen by the definition of
6745 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
6746 and FLOCK for flock(). New options have been added:
6747 - SYSVSEM to use System V style semaphores
6748 - PTHREAD to use POSIX threads (appears to work on Solaris only)
6749 - USLOCK to use IRIX uslock
6750 Based on timing various techniques, the following changes were made
6752 - Linux 2.x uses flock instead of fcntl
6753 - Solaris 2.x uses pthreads
6754 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
6755 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
6756 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
6757 Martijn Koster <m.koster@pobox.com>]
6759 *) PORT: The semantics of accept/select make it very desirable to use
6760 mutexes to serialize accept when multiple Listens are in use. But
6761 in the case where only a single socket is open it is sometimes
6762 redundant to serialize accept(). Not all unixes do a good job with
6763 potentially dozens of children blocked on accept() on the same
6764 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
6765 the server will avoid serialization when listening on only one socket,
6766 and use serialization when listening on multiple sockets.
6767 [Dean Gaudet] PR#467
6769 *) Configure changes: TestLib replaced by TestCompile, which has
6770 some additional capability (such as doing a sanity check of
6771 the compiler and flags selected); the version of Solaris is now
6772 available via the #define value of SOLARIS2; IRIX n32bit libs
6773 now supported and selectable by new Configuration Rule: IRIXN32;
6774 We no longer default to -O2 optimization. [Jim Jagielski]
6776 *) Updated Configure: Configuration now uses AddModule to specify
6777 module source or binary file location, relative to src directory.
6778 Modules can be dropped into modules/extra, or in their own
6779 directory, and modules can come with a Makefile or Configure can
6780 create one. Modules can add compiler or library information to
6781 generated Makefiles. [Paul Sutton]
6783 *) Source core re-organisation: distributed modules are now in
6784 modules/standard. All other source code is in main. OS-specific
6785 code is in os/{unix,emx,win32} directories. [Paul Sutton]
6787 *) mod_browser has been removed, since it's replaced by mod_setenvif.
6790 *) Fix another long-standing bug in sub_req_lookup_file where it would
6791 happily skip past access checks on subdirectories looked up with
6792 relative paths. (It's used by mod_dir, mod_negotiation,
6793 and mod_include.) [Dean Gaudet]
6795 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
6796 N is the number of <Directory> sections, and M is the number of
6797 components in the filename of an object.
6799 To achieve this optimization the following config changes were made:
6800 - Wildcards (* and ?, not the regex forms) in <Directory>s,
6801 <Files>s, and <Location>s now treat a slash as a special
6802 character. For example "/home/*/public_html" previously would
6803 match "/home/a/andrew/public_html", now it only matches things
6804 like "/home/bob/public_html". This mimics /bin/sh behaviour.
6805 - It's possible now to use [] wildcarding in <Directory>, <Files>
6807 - Regex <Directory>s are applied after all non-regex <Directory>s.
6811 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
6812 and corrupted paths. [Dean Gaudet]
6814 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
6815 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
6816 be accessed now via backreferences $1..$9 in RewriteConds test-against
6817 strings in addition to RewriteRules subst string. Second the grouped
6818 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
6819 via backreferences %1..%9 both in following RewriteCond test-against
6820 strings and RewriteRules subst string. This provides maximum flexibility
6821 through the use of backreferences.
6822 Additionally the rewriting engine was cleaned up by putting common
6823 code to the new expand_backrefs_inbuffer() function.
6824 [Ralf S. Engelschall]
6826 *) When merging the main server's <Directory> and <Location> sections into
6827 a vhost, put the main server's first and the vhost's second. Otherwise
6828 the vhost can't override the main server. [Dean Gaudet] PR#717
6830 *) The <Directory> code would merge and re-merge the same section after
6831 a match was found, possibly causing problems with some modules.
6834 *) ip-based vhosts are stored and queried using a hashing function, which
6835 has been shown to improve performance on servers with many ip-vhosts.
6836 Some other changes had to be made to accommodate this:
6837 - the * address for vhosts now behaves like _default_
6838 - the matching process now is:
6839 - match an ip-vhost directly via hash (possibly matches main
6841 - if that fails, just pretend it matched the main server
6842 - if so far only the main server has been matched, perform
6843 name-based lookups (ServerName, ServerAlias, ServerPath)
6844 *only on name-based vhosts*
6845 - if they fail, look for _default_ vhosts
6846 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
6848 *) dbmmanage overhaul:
6849 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
6850 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
6851 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
6852 - provide better seed for rand
6853 - prompt for password as per getpass(3) (turn off echo, read from
6855 - use "newstyle" crypt based on $Config{osname} ($^O)
6856 - will not add a user if already in database, use new `update' command
6858 - added `check' command to check a users' password
6859 - added `import' command to convert existing password text-files or
6860 dbm files exported with `view'
6861 - more descriptive usage, general cleanup, 'use strict' clean, etc.
6864 *) Added psocket() which is a pool form of socket(), various places within
6865 the proxy weren't properly blocking alarms while registering the cleanup
6866 for its sockets. bclose() now uses pclose() and pclosesocket(). There
6867 was a bug where the client socket was being close()d twice due a still
6868 registered cleanup. [Dean Gaudet]
6870 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
6873 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
6874 [Jason Venner <jason@idiom.com>] PR#667
6876 *) Enable ``=""'' for RewriteCond directives to match against
6877 the empty string. This is the preferred way instead of ``^$''.
6878 [Ralf S. Engelschall]
6880 *) Fixed an infinite loop in mod_imap for references above the server root
6881 [Dean Gaudet] PR#748
6883 *) mod_proxy now has a ReceiveBufferSize directive, similar to
6884 SendBufferSize, so that the TCP window can be set appropriately
6885 for LFNs. [Phillip A. Prindeville]
6887 *) mod_browser has been replaced by the more general mod_setenvif
6888 (courtesy of Paul Sutton). BrowserMatch* directives are still
6889 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
6890 UnSetEnvIfZero directives. [Ken Coar]
6892 *) "HostnameLookups double" forces double-reverse DNS to succeed in
6893 order for remote_host to be set (for logging, or for the env var
6894 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
6897 *) mod_access overhaul:
6898 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
6899 and cidr syntax (i.e. 10.1.0.0/16). PR#762
6900 - Critical path was sped up by pre-computing a few things at config time.
6901 - The undocumented syntax "allow user-agents" was removed,
6902 the replacement is "allow from env=foobar" combined with mod_browser.
6903 - When used with hostnames it now forces a double-reverse lookup
6904 no matter what the directory settings are. This double-reverse
6905 doesn't affect any of the other routines that use the remote
6906 hostname. In particular it's still passed to CGIs and the log
6907 without the double-reverse check. Related PR#860.
6910 *) When a large bwrite() occurs (larger than the internal buffer size),
6911 while there is already something in the buffer, apache will combine
6912 the large write and the buffer into a single writev(). (This is
6913 in anticipation of using mmap() for reading files.)
6916 *) In obscure cases where a partial socket write occurred while chunking,
6917 Apache would omit the chunk header/footer on the next block. Cleaned
6918 up other bugs/inconsistencies in error conditions in buff.c. Fixed
6919 a bug where a long pause in DNS lookups could cause the last packet
6920 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
6922 *) API: Added child_exit function to module structure. This is called
6923 once per "heavy-weight process" just before a server child exit()'s
6924 e.g. when max_requests_per_child is reached, etc.
6925 [Doug MacEachern, Dean Gaudet]
6927 *) mod_include cleanup showed that handle_else was being used to handle
6928 endif. It didn't cause problems, but it was cleaned up too.
6931 *) mod_cern_meta would attempt to find meta files for the directory itself
6932 in some cases, but not in others. It now avoids it in all cases.
6935 *) mod_mime_magic would core dump if there was a decompression error.
6936 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
6938 *) PORT: some variants of DGUX require -lsocket -lnsl
6939 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
6941 *) mod_autoindex now allows sorting of FancyIndexed directory listings
6942 by the various fields (name, size, et cetera), either in ascending
6943 or descending order. Just click on the column header. [Ken Coar]
6945 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
6946 CPUs like the Alpha. Apache still stores ints in pointers, but that's
6947 the relatively safe direction. [Dean Gaudet] PR#344
6949 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
6950 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
6952 *) child_main avoids an unneeded call to select() when there is only one
6953 listening socket. [Dean Gaudet]
6955 *) In the event that the server is starved for idle servers it will
6956 spawn 1, then 2, then 4, ..., then 32 servers each second,
6957 doubling each second. It'll also give a warning in the errorlog
6958 since the most common reason for this is a poor StartServers
6959 setting. The define MAX_SPAWN_RATE can be used to raise/lower
6960 the maximum. [Dean Gaudet]
6962 *) Apache now provides an effectively unbuffered connection for
6963 CGI scripts. This means that data will be sent to the client
6964 as soon as the CGI pauses or stops output; previously, Apache would
6965 buffer the output up to a fixed buffer size before sending, which
6966 could result in the user viewing an empty page until the CGI finished
6967 or output a complete buffer. It is no longer necessary to use an
6968 "nph-" CGI to get unbuffered output. Given that most CGIs are written
6969 in a language that by default does buffering (e.g. perl) this
6970 shouldn't have a detrimental effect on performance.
6972 "nph-" CGIs, which formerly provided a direct socket to the client
6973 without any server post-processing, were not fully compatible with
6974 HTTP/1.1 or SSL support. As such they would have had to implement
6975 the transport details, such as encryption or chunking, in order
6976 to work properly in certain situations. Now, the only difference
6977 between nph and non-nph scripts is "non-parsed headers".
6978 [Dean Gaudet, Sameer Parekh, Roy Fielding]
6980 *) If a BUFF is switched from buffered to unbuffered reading the first
6981 bread() will return whatever remained in the buffer prior to the
6982 switch. [Dean Gaudet]
6984 Changes with Apache 1.3a1
6986 *) Added another Configure helper script: TestLib. It determines
6987 if a specified library exists. [Jim Jagielski]
6989 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
6990 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
6993 *) PORT: Some architectures use size_t for various lengths in network
6994 functions such as accept(), and getsockname(). The definition
6995 NET_SIZE_T is used to control this. [Dean Gaudet]
6997 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
6998 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
6999 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
7001 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
7002 [Igor N Kovalenko <infoh@mail.wplus.net>]
7004 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7005 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7006 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
7007 [Dean Gaudet] related PR#875
7009 *) API: Correct child_init() slot declaration from int to void, to
7010 match the init() declaration. Update mod_example to use the new
7013 *) added transport handle slot (t_handle) to the BUFF structure
7016 *) get_client_block() returns wrong length if policy is
7017 REQUEST_CHUNKED_DECHUNK.
7018 [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815
7020 *) Support the image map format of FrontPage. For example:

7024 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
7025 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
7027 *) AddModuleInfo directive for mod_info which allows you to annotate
7028 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
7030 *) Added NoProxy directive to avoid using ProxyRemote for selected
7031 addresses. Added ProxyDomain directive to cause unqualified
7032 names to be qualified by redirection.
7033 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
7035 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
7036 header to the remote host in the proxy. [Sameer Parekh and
7039 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
7040 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
7041 URLs, fixed rewritelog(), fixed forced response code handling on
7042 redirects from within .htaccess files, disabled pipe locking under
7043 braindead SunOS 4.1.x, allow env variables to be set even on rules with
7044 no substitution, bugfixed situations where HostnameLookups is off, made
7045 mod_rewrite more thread-safe for NT port and fixed problem when creating
7046 an empty query string via "xxx?".
7047 This update also removes the copyright of Ralf S. Engelschall,
7048 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
7049 exclusively copyrighted by the Apache Group now. This happened because
7050 the author now has gifted mod_rewrite exclusively to the Apache Group and
7051 no longer maintains an external version.
7052 [Ralf S. Engelschall]
7054 *) API: Added child_init function to module structure. This is called
7055 once per "heavy-weight process" before any requests are handled.
7056 See http_config.h for more details. [Dean Gaudet]
7058 *) Anonymous_LogEmail was logging on each subrequest.
7059 [Dean Gaudet] PR#421, 868
7061 *) API: Added is_initial_req() which tests if the request being
7062 processed is the initial request, or a subrequest.
7065 *) Extended SSI (mod_include) now handles additional relops for
7066 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
7068 *) Configure fixed to correctly propagate user-selected options and
7069 settings (such as CC and OPTIM) to Makefiles other than
7070 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
7072 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
7073 directory indices to start with the contents of the HeaderName file
7074 if there is one. If there isn't one, the behaviour is unchanged.
7075 [Ken Coar, Roy Fielding, Andrey A. Chernov]
7077 *) WIN32: Modules can now be dynamically loaded DLLs using the
7078 LoadModule/LoadFile directives. Note that module DLLs must be
7079 compiled with the multithreaded DLL version of the runtime library.
7080 [Alexei Kosut and Ben Laurie]
7082 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
7083 This allows the admin to completely remove automatic indexing
7084 from the server, while still supporting the basic functions of
7085 trailing-slash redirects and DirectoryIndex files. Note that if
7086 you're carrying over an old Configuration file and you use directory
7087 indexing then you'll want to add:
7089 Module autoindex_module mod_autoindex.o
7091 before mod_dir in your Configuration. [Dean Gaudet]
7093 *) popendir/pclosedir created to properly protect directory scanning.
7094 [Dean Gaudet] PR#525
7096 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
7097 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
7098 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
7101 *) The AccessFileName directive can now take more than one filename.
7102 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
7104 *) The new mod_mime_magic can be used to "magically" determine the type
7105 of a file if the extension is unknown. Based on the unix file(1)
7106 command. [Ian Kluft <ikluft@cisco.com>]
7108 *) We now determine and display the time spent processing a
7109 request if desired. [Jim Jagielski]
7111 *) mod_status: PID field of "dead" child slots no longer displays
7112 main httpd process's PID. [Jim Jagielski]
7114 *) Makefile.nt added - to build all the bits from the command line:
7115 nmake -f Makefile.nt
7116 Doesn't yet work properly. [Ben Laurie]
7118 *) Default text of 404 error is now "Not Found" rather than the
7119 potentially misleading "File Not Found". [Ken Coar]
7121 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
7122 for the net if we require people that actually need this data to
7123 enable it. [Linus Torvalds]
7125 *) directory_walk() is an expensive function, keep a little more state to
7126 avoid needless string counting. Add two new functions make_dirstr_parent
7127 and make_dirstr_prefix which replace all existing uses of make_dirstr.
7128 The new functions are a little less general than make_dirstr, but
7129 work more efficiently (less memory, less string counting).
7132 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
7133 to LDFLAGS) to avoid complications with lex rules in make files.
7134 [Dean Gaudet] PR#372
7136 *) run_method optimized to avoid needless scanning over NULLs in the
7137 module list. [Dean Gaudet]
7139 *) Revamp of (unix) scoreboard management code such that it avoids
7140 unnecessary traversals of the scoreboard on each hit. This is
7141 particularly important for high volume sites with a large
7142 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
7143 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
7144 httpd.h. [Dean Gaudet]
7146 *) In configurations using multiple Listen statements it was possible for
7147 busy sockets to starve other sockets of service. [Dean Gaudet]
7149 *) Added hook so standalone_main can be replaced at compile time
7150 (define STANDALONE_MAIN)
7153 *) Lowest-level read/write functions in buff.c will be replaced with
7154 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
7155 compile time. The default sfio discipline will behave as apache
7156 would without sfio compiled in.
7159 *) Enhance UserDir directive (mod_userdir) to accept a list of
7160 usernames for the 'disable' keyword, and add 'enable user...' to
7161 selectively *en*able userdirs if they're globally disabled.
7164 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
7165 will work with Netscape dbm files. (dbmmanage will probably not
7166 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
7168 *) Add a ListenBacklog directive to control the backlog parameter
7169 passed to listen(). Also change the default to 511 from 512.
7172 *) API: A new handler response DONE which informs apache that the
7173 request has been handled and it can finish off quickly, similar to
7174 how it handles errors. [Rob Hartill]
7176 *) Turn off chunked encoding after sending terminating chunk/footer
7177 so that we can't do it twice by accident. [Roy Fielding]
7179 *) mod_expire also issues Cache-Control: max-age headers.
7182 *) API: Added kill_only_once option for free_proc_chain so that it won't
7183 aggressively try to kill off specific children. For fastcgi.
7184 [Stanley Gambarin <gambarin@OpenMarket.com>]
7186 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
7188 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
7189 When used together, these cause mod_dir to emit HEIGHT and WIDTH
7190 attributes in the FancyIndexing IMG tags. [Ken Coar]
7192 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
7194 *) PORT: Added Windows NT support
7195 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
7197 Changes with Apache 1.2.6
7199 *) mod_include when using XBitHack Full would send ETags in addition to
7200 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
7201 [Dean Gaudet] PR#1133
7203 *) SECURITY: When a client connects to a particular port/addr, and
7204 gives a Host: header ensure that the virtual host requested can
7205 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
7207 *) Support virtual hosts with wildcard port and/or multiple ports
7208 properly. [Ed Korthof <ed@organic.com>]
7210 *) Fixed some case-sensitivity issues according to RFC2068.
7213 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
7214 and mod_include.c. [Dean Gaudet]
7216 *) Variable 'cwd' was being used pointlessly before being set.
7219 *) SIGURG doesn't exist on all platforms.
7220 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
7222 *) When an error occurs during a POST, or other operation with a
7223 request body, the body has to be read from the net before allowing
7224 a keepalive session to continue. [Roy Fielding] PR#1399
7226 *) When an error occurs in fcntl() locking suggest the user look up
7227 the docs for LockFile. [Dean Gaudet]
7229 *) table_set() and table_unset() did not deal correctly with
7230 multiple occurrences of the same key. [Stephen Scheck
7231 <sscheck@infonex.net>, Ben Laurie] PR#1604
7233 *) send_fd_length() did not calculate total_bytes_sent properly in error
7234 cases. [Ben Reser <breser@regnow.com>] PR#1366
7236 *) r->connection->user was allocated in the wrong pool causing corruption
7237 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
7239 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7240 Also removed the auto-generated link to www.apache.org that was the
7241 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7243 *) Multiple "close" tokens may have been set in the "Connection"
7244 header, not an error, but a waste.
7245 [Ronald.Tschalaer@psi.ch] PR#1683
7247 *) "basic" and "digest" auth tokens should be tested case-insensitive.
7248 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
7250 *) It appears the "257th byte" bug (see
7251 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
7252 at the 256th byte as well. Fixed. [Dean Gaudet]
7254 *) mod_rewrite would not handle %3f properly in some situations.
7257 *) Apache could generate improperly chunked HTTP/1.1 responses when
7258 the bputc() or rputc() functions were used by modules (such as
7259 mod_include). [Dean Gaudet]
7261 *) #ifdef wrap a few #defines in httpd.h to make life easier on
7262 some ports. [Ralf Engelschall]
7264 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
7266 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
7268 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
7270 Changes with Apache 1.2.5
7272 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
7273 only an issue on systems without a MAXDNAME define or where
7274 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
7276 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
7279 *) Fix core dump in the ftp proxy when reading incorrectly formatted
7280 directory listings. [Marc Slemko]
7282 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
7285 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
7286 is used to read various types of files such as htaccess and
7287 htpasswd files. [Marc Slemko]
7289 *) SECURITY: Ensure that the buffer returned by ht_time is always
7290 properly null terminated. [Marc Slemko]
7292 *) SECURITY: General mod_include cleanup, including fixing several
7293 possible buffer overflows and a possible infinite loop. This cleanup
7294 was done against 1.3 code and then backported to 1.2, the result
7295 is a large difference (due to indentation cleanup in 1.3 code).
7296 Users interested in seeing a smaller set of relevant differences
7297 should consider comparing against src/modules/standard/mod_include.c
7298 from the 1.3b3 release. Non-indentation changes to mod_include
7299 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
7301 *) SECURITY: Numerous changes to mod_imap in a general cleanup
7302 including fixing a possible buffer overflow. This cleanup also
7303 was done with 1.3 code as a basis, see the the previous note
7304 about mod_include. [Dean Gaudet]
7306 *) SECURITY: If a htaccess file can not be read due to bad
7307 permissions, deny access to the directory with a HTTP_FORBIDDEN.
7308 The previous behavior was to ignore the htaccess file if it could not
7309 be read. This change may make some setups with unreadable
7310 htaccess files stop working. PR#817 [Marc Slemko]
7312 *) SECURITY: no2slash() was O(n^2) in the length of the input.
7313 Make it O(n). This inefficiency could be used to mount a denial
7314 of service attack against the Apache server. Thanks to
7315 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting
7318 *) mod_include used uninitialized data for some uses of && and ||.

7322 [Jay Bloodworth <jay@pathways.sde.state.sc.us>]
7324 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7326 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7327 r->filename. Since those two are meant to be in sync with each other
7328 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
7330 *) mod_include did not properly handle all possible redirects from sub-

7333 *) Inetd mode (which is buggy) uses timeouts without having setup the
7334 jmpbuffer. [Dean Gaudet] PR#1064
7336 *) Work around problem under Linux where a child will start looping
7337 reporting a select error over and over.
7338 [Rick Franchuk <rickf@transpect.net>] PR#1107
7340 Changes with Apache 1.2.4
7342 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
7343 always making requests with the full-URI instead of just the URI path.
7344 [Marc Slemko, Roy Fielding]
7346 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
7347 on this platform. [Marc Slemko]
7349 Changes with Apache 1.2.3
7351 *) The request to a remote proxy was mangled if it was generated as the
7352 result of a ProxyPass directive. URL schemes other than http:// were not
7353 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
7354 PR#812 [Lars Eilebrecht]
7356 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7357 information for case where proxy module is not available. [Marc Slemko]
7359 *) Force proxy to always respond as HTTP/1.0, which it was failing to
7360 do for errors and cached responses. [Roy Fielding]
7362 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
7364 Changes with Apache 1.2.2 [not released]
7366 *) Fixed another long-standing bug in sub_req_lookup_file where it would
7367 happily skip past access checks on subdirectories looked up with relative
7368 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
7371 *) Add lockfile name to error message printed out when
7372 USE_FLOCK_SERIALIZED_ACCEPT is defined.
7375 *) Enhanced the chunking and error handling inside the buffer functions.
7376 [Dean Gaudet, Roy Fielding]
7378 *) When merging the main server's <Directory> and <Location> sections into
7379 a vhost, put the main server's first and the vhost's second. Otherwise
7380 the vhost can't override the main server. [Dean Gaudet] PR#717
7382 *) The <Directory> code would merge and re-merge the same section after
7383 a match was found, possibly causing problems with some modules.
7386 *) Fixed an infinite loop in mod_imap for references above the server root.
7387 [Dean Gaudet] PR#748
7389 *) mod_include cleanup showed that handle_else was being used to handle
7390 endif. It didn't cause problems, but it was cleaned up too.
7393 *) Last official synchronization of mod_rewrite with author version (because
7394 mod_rewrite is now directly developed by the author at the Apache Group):
7395 o added diff between mod_rewrite 3.0.6+ and 3.0.9
7396 minus WIN32/NT stuff, but plus copyright removement.
7398 - workaround for detecting infinite rewriting loops
7399 - fixed setting of env vars when "-" is used as subst string
7400 - fixed forced response code on redirects (PR#777)
7401 - fixed cases where r->args is ""
7402 - kludge to disable locking on pipes under braindead SunOS
7403 - fix for rewritelog in cases where remote hostname is unknown
7404 - fixed totally damaged request_rec walk-back loop
7405 o remove static from local data and add static to global ones.
7406 o replaced ugly proxy finding stuff by simple
7407 find_linked_module("mod_proxy") call.
7408 o added missing negation char on rewritelog()
7409 o fixed a few comment typos
7410 [Ralf S. Engelschall]
7412 *) Anonymous_LogEmail was logging on each subrequest.

7415 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7416 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7417 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
7418 Additionally mod_browser now triggers during translate_name to workaround
7419 a deficiency in the header_parse phase.

7440 *) API: In HTTP/1.1, whether or not a request message contains a body
7441 is independent of the request method and based solely on the presence
7442 of a Content-Length or Transfer-Encoding. Therefore, our default
7443 handlers need to be prepared to read a body even if they don't know
7444 what to do with it; otherwise, the body would be mistaken for the
7445 next request on a persistent connection. discard_request_body()
7446 has been added to take care of that. [Roy Fielding] PR#378

7454 Changes with Apache 1.2.1
7456 *) SECURITY: Don't serve file system objects unless they are plain files,
7457 symlinks, or directories. This prevents local users from using pipes
7458 or named sockets to invoke programs for an extremely crude form of
7461 *) SECURITY: HeaderName and ReadmeName were settable in .htaccess and
7462 could contain "../" allowing a local user to "publish" any file on
7463 the system. No slashes are allowed now. [Dean Gaudet]
7465 *) SECURITY: It was possible to violate the symlink Options using mod_dir
7466 (headers, readmes, titles), mod_negotiation (type maps), or
7467 mod_cern_meta (meta files). [Dean Gaudet]
7469 *) SECURITY: Apache will refuse to run as "User root" unless
7470 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
7472 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
7473 if it contained a .htaccess disallowing symlinks. This is contrary
7474 to the rule that symlink permissions are tested with the symlink
7475 options of the parent directory. [Dean Gaudet] PR#353
7477 *) CONFIG: The LockFile directive can be used to place the serializing
7478 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
7479 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
7482 *) Request processing now retains state of whether or not the request
7483 body has been read, so that internal redirects and subrequests will
7484 not try to read it twice (and block). [Roy Fielding]
7486 *) Add a placeholder in modules/Makefile to avoid errors with certain
7487 makes. [Marc Slemko]
7489 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.
7490 [Dean Gaudet] PR#644
7492 *) mod_include was not properly changing the current directory.
7493 [Marc Slemko] PR#742
7495 *) Attempt to work around problems with third party libraries that do not
7496 handle high numbered descriptors (examples include bind, and
7497 solaris libc). On all systems apache attempts to keep all permanent
7498 descriptors above 15 (called the low slack line). Solaris users
7499 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
7500 which keeps all non-FILE * descriptors above 255. On all systems
7501 this should make supporting large numbers of vhosts with many open
7502 log files more feasible. If this causes trouble please report it,
7503 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
7504 [Dean Gaudet] various PRs
7506 *) Related to the last entry, network sockets are now opened before
7507 log files are opened. The only known case where this can cause
7508 problems is under Solaris with many virtualhosts and many Listen
7509 directives. But using -DHIGH_SLACK_LINE=256 described above will
7510 work around this problem. [Dean Gaudet]
7512 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
7515 *) Improved unix error response logging. [Marc Slemko]
7517 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
7518 QSA=query_string_append. Also fixed a nasty bug in per-dir context:

7584 *) If multiple requests on a single connection are used to retrieve

7601 *) If a soft_timeout occurs after keepalive is set, then the main child

7603 has been aborted. [Roy Fielding]
7605 *) Configure changes: Allow for whitespace at the start of a
7606 Module declaration. Also, be more understanding about the
7607 CC=/OPTIM= format in Configuration. Finally, fix compiler
7608 flags if using HP-UX's cc compiler. [Jim Jagielski]
7610 *) Subrequests and internal redirects now inherit the_request from the
7611 original request-line. [Roy Fielding]
7613 *) Test for error conditions before creating output header fields, since
7614 we don't want the error message to include those fields. Likewise,
7615 reset the content_language(s) and content_encoding of the response
7616 before generating or redirecting to an error message, since the new
7617 message will have its own Content-* definitions. [Dean Gaudet]
7619 *) Restored the semantics of headers_out (headers sent only with 200..299
7620 and 304 responses) and err_headers_out (headers sent with all responses).
7621 Avoid the overhead of copying tables if err_headers_out is empty
7622 (the usual case). [Roy Fielding]
7624 *) Fixed a couple places where a check for the default Content-Type was
7625 not properly checking both the value configured by the DefaultType
7626 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
7627 of DEFAULT_TYPE to match the documented default (text/plain).

7630 *) Escape the HTML-sensitive characters in the Request-URI that is
7631 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
7633 *) Properly initialize the flock structures used by the mutex locking
7634 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
7637 *) The method for determining PATH_INFO has been restored to the pre-1.2b
7638 (and NCSA httpd) definition wherein it was the extra path info beyond
7639 the CGI script filename. The environment variable FILEPATH_INFO has
7640 been removed, and instead we supply the original REQUEST_URI to any
7641 script that wants to be Apache-specific and needs the real URI path.
7642 This solves a problem with existing scripts that use extra path info
7643 in the ScriptAlias directive to pass options to the CGI script.
7646 *) The _default_ change in 1.2b10 will change the behaviour on configs
7647 that use multiple Listen statements for listening on multiple ports.
7648 But that change is necessary to make _default_ consistent with other
7649 forms of <VirtualHost>. It requires such configs to be modified
7650 to use <VirtualHost _default_:*>. The documentation has been
7651 updated. [Dean Gaudet] PR#530
7653 *) If an ErrorDocument CGI script is used to respond to an error
7654 generated by another CGI script which has already read the message
7655 body of the request, the server would block trying to read the
7656 message body again. [Rob Hartill]
7658 *) signal() replacement conflicted with a define on QNX (and potentially
7659 other platforms). Fixed. [Ben Laurie] PR#512
7661 Changes with Apache 1.2b10
7663 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
7664 to be configured via -D in Configuration. [Dean Gaudet] PR#449

7675 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
7677 Changes with Apache 1.2b9 [never announced]
7679 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
7680 changes and in anticipation of 1.2 final release. [Roy Fielding]
7682 *) Fix problem with scripts not receiving a SIGPIPE when client drops
7683 the connection (e.g., when user presses Stop). Apache will now stop
7684 trying to send a message body immediately after an error from write.
7685 [Roy Fielding and Nathan Kurz] PR#335
7687 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
7688 than mod_alias, and mod_alias has higher priority than mod_proxy;
7689 rearranged other modules to enhance understanding of their purpose
7690 and relative order (and maybe even reduce some overhead).
7691 [Roy Fielding and Sameer Parekh]
7693 *) Fix graceful restart. Eliminate many signal-related race
7694 conditions in both forms of restart, and in SIGTERM. See
7695 htdocs/manual/stopping.html for details on stopping and
7696 restarting the parent. [Dean Gaudet]
7698 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
7699 memory allocator to avoid a behaviour that required extra blocks to
7700 be allocated. [Dean Gaudet]
7702 *) Allow suexec to access files relative to current directory but not
7703 above. (Excluding leading / or any .. directory.) [Ken Coar]
7706 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
7707 PR#367, 368, 354, 453
7709 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
7710 while obtaining the /~user and save the username in a separate data
7711 area so that it won't be overwritten by the call to getgrgid(), and
7712 fix some misuse of the pool string allocation functions. Also fixes
7713 a general problem with parsing URL query info into args for CGI scripts.

7721 AuthDBAuthoritative. [Marc Slemko] PR#420
7723 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
7725 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
7726 object that can't be PUT, or FOOBAR for some method FOOBAR that
7727 apache doesn't know about at all). Log 404s that occur in mod_include.
7728 [Paul Sutton, John Van Essen]
7730 *) If a soft timeout (or lingerout) occurs while trying to flush a
7731 buffer or write inside buff.c or fread'ing from a CGI's output,
7732 then the timeout would be ignored. [Roy Fielding] PR#373
7734 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
7735 parsing of headers. If the terminating empty-line CRLF occurs starting
7736 at the 256th or 257th byte of output, then Navigator will think a normal
7737 image is invalid. We are guessing that this is because their initial
7738 read of a new request uses a 256 byte buffer. We check the bytes written
7739 so far and, if we are about to tickle the bug, we instead insert a
7740 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
7742 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
7743 of an external redirection. [Roy Fielding and Paul Sutton]
7745 *) Configure would create a broken Makefile if the configuration file
7746 contained a commented-out Rule. [Roy Fielding]
7748 *) Promote per_dir_config and subprocess_env from the subrequest to the
7749 main request in mod_negotiation. In particular this fixes a bug
7750 where <Files> sections wouldn't properly apply to negotiated content.
7753 *) Fix a potential deadlock in mod_cgi script_err handling.
7754 [Ralf S. Engelschall]
7756 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
7759 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
7760 .htaccess files because the RewriteBase was not replaced correctly.
7761 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
7762 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
7764 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
7765 1.x the settings are those of pre-1.2b8. For 2.x we include
7766 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
7767 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
7768 [Dean Gaudet] PR#336, PR#340
7770 *) Redirect did not preserve ?query_strings when present in the client's
7771 request. [Dean Gaudet]

7775 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
7777 *) Add UnixWare compile/install instructions. [Chuck Murcko]
7779 *) Add mod_example (illustration of API techniques). [Ken Coar]
7781 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
7783 *) Improve handling of directories when filenames have spaces in them.
7786 *) For hosts with multiple IP addresses, try all additional addresses if
7787 necessary to get a connect. Fail only if hostent address list is
7788 exhausted. [Chuck Murcko]
7790 *) More signed/unsigned port fixes. [Dean Gaudet]
7792 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
7795 Changes with Apache 1.2b8
7797 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
7798 to it. [Marc Slemko]
7800 *) The addition of <Location> and <File> directives made the
7801 sub_req_lookup_simple() function bogus, so we now handle
7802 the special cases directly. [Dean Gaudet]
7804 *) We now try to log where the server is dumping core when a fatal
7805 signal is received. [Ken Coar]
7807 *) Improved lingering_close by adding a special timeout, removing the
7808 spurious log messages, removing the nonblocking settings (they
7809 are not needed with the better timeout), and adding commentary
7810 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
7811 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
7813 *) Send error messages about setsockopt failures to the server error
7814 log instead of stderr. [Roy Fielding]
7816 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
7818 *) Stopgap solution for CGI 3-second delay with server-side includes: if
7819 processing a subrequest, allocate memory from r->main->pool instead
7820 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
7821 in the middle of an SSI request. [Dean Gaudet] PR #122
7823 *) Fixed status of response when POST is received for a nonexistent URL
7824 (was sending 405, now 404) and when any method is sent with a
7825 full-URI that doesn't match the server and the server is not acting
7826 as a proxy (was sending 501, now 403). [Roy Fielding]
7828 *) Host port changed to unsigned short. [Ken Coar] PR #276
7830 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
7832 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
7834 *) Report extra info from errno with many errors that cause httpd to exit.
7835 spawn_child, popenf, and pclosef now have valid errno returns in the
7836 event of an error. Correct problems where errno was stomped on
7837 before being reported. [Dean Gaudet]
7839 *) In the proxy, if the cache filesystem was full, garbage_coll() was
7840 never called, and thus the filesystem would remain full indefinitely.
7841 We now also remove incomplete cache files left if the origin server
7842 didn't send a Content-Length header and either the client has aborted
7843 transfer or bwrite() to client has failed. [Petr Lampa]
7845 *) Fixed the handling of module and script-added header fields.
7846 Improved the interface for sending header fields and reduced
7847 the duplication of code between sending okay responses and errors.
7848 We now always send both headers_out and err_headers_out, and
7849 ensure that the server-reserved fields are not being overridden,
7850 while not overriding those that are not reserved. [Roy Fielding]
7852 *) Moved transparent content negotiation fields to err_headers_out
7853 to reflect above changes. [Petr Lampa]
7855 *) Fixed the determination of whether or not we should make the
7856 connection persistent for all of the cases where some other part
7857 of the server has already indicated that we should not. Also
7858 improved the ordering of the test so that chunked encoding will
7859 be set whenever it is desired instead of only when KeepAlive
7860 is enabled. Added persistent connection capability for most error
7861 responses (those that do not indicate a bad input stream) when
7862 accessed by an HTTP/1.1 client. [Roy Fielding]
7864 *) Added missing timeouts for sending header fields, error responses,
7865 and the last chunk of chunked encoding, each of which could have
7866 resulted in a process being stuck in write forever. Using soft_timeout
7867 requires that the sender check for an aborted connection rather than
7868 continuing after an EINTR. Timeouts that used to be initiated before
7869 send_http_header (and never killed) are now initiated only within or
7870 around the routines that actually do the sending, and not allowed to
7871 propagate above the caller. [Roy Fielding]
7873 *) mod_auth_anon required an @ or a . in the email address, not both.
7876 *) per_dir_defaults weren't set correctly until directory_walk for
7877 name-based vhosts. This fixes an obscure bug with the wrong config
7878 info being used for vhosts that share the same ip as the server.
7881 *) Improved generation of modules/Makefile to be more generic for
7882 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
7884 *) Generate makefile dependency for Configuration based on the actual
7885 name given when running the Configure process. [Dean Gaudet]
7887 *) Fixed problem with vhost error log not being set prior to
7888 initializing virtual hosts. [Dean Gaudet]
7890 *) Fixed infinite loop when a trailing slash is included after a type map
7891 file URL (extra path info). [Petr Lampa]
7893 *) Fixed server status updating of per-connection counters. [Roy Fielding]
7895 *) Add documentation for DNS issues (reliability and security), and try
7896 to explain the virtual host matching process. [Dean Gaudet]
7898 *) Try to continue gracefully by disabling the vhost if a DNS lookup
7899 fails while parsing the configuration file. [Dean Gaudet]
7901 *) Improved calls to setsockopt. [Roy Fielding]
7903 *) Negotiation changes: Don't output empty content-type in variant list;
7904 Output charset in variant list; Return sooner from handle_multi() if
7905 no variants found; Add handling of '*' wildcard in Accept-Charset.
7906 [Petr Lampa and Paul Sutton]
7908 *) Fixed overlaying of request/sub-request notes and headers in
7909 mod_negotiation. [Dean Gaudet]
7911 *) If two variants' charset quality are equal and one is the default
7912 charset (iso-8859-1), then prefer the variant that was specifically
7913 listed in Accept-Charset instead of the default. [Petr Lampa]
7915 *) Memory allocation problem in push_array() -- it would corrupt memory
7916 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
7918 *) invoke_handler() doesn't handle mime arguments in content-type
7921 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
7924 *) Fixed problem with ErrorDocument not working for virtual hosts
7925 due to one of the performance changes in 1.2b7. [Dean Gaudet]
7927 *) Log an error message if we get a request header that is too long,
7928 since it may indicate a buffer overflow attack. [Marc Slemko]
7930 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
7931 not reject URLs without a double-slash, as per RFC2068 section 3.2.
7932 [Ken Coar] PR #146, #187
7934 *) Added table entry placeholder for new header_parser callback
7935 in all of the distributed modules. [Ken Coar] PR #191
7937 *) Allow for cgi files without the .EXE extension on them under OS/2.
7938 [Garey Smiley] PR #59
7940 *) Fixed error message when resource is not found and URL contains
7941 path info. [Petr Lampa and Dean Gaudet] PR #40
7943 *) Fixed user and server confusion over what should be a virtual host
7944 and what is the main server, resulting in access to something
7945 other than the name defined in the virtualhost directive (but
7946 with the same IP address) failing. [Dean Gaudet]
7948 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
7949 AIX; improves the redirection stuff to enable the users to generally
7950 redirect to http, https, gopher and ftp; added TIME variable for
7951 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
7952 special patterns >STRING, <STRING and =STRING to RewriteCond, which
7953 can be used in conjunction with %{TIME} or other variables to create
7954 time-dependent rewriting rules. [Ralf S. Engelschall]
7956 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
7957 Module authors may need to adjust their code for proper cleanup to take
7958 place (that is, call note_cleanups_for_fd()). This change fixes problems
7959 with file descriptors being erroneously closed when the proxy module was
7960 in use. [Ben Laurie]
7962 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
7963 initgroups() to hose the group information needed for later
7964 comparisons. [Randy Terbush]
7966 *) Remove unnecessary call to va_end() in create_argv() which
7967 caused a SEGV on some systems.
7969 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
7972 *) Clear memory allocated for listeners. [Randy Terbush]
7974 *) Improved handling of IP address as a virtualhost address and
7975 introduced "_default_" as a synonym for the default vhost config.
7976 [Dean Gaudet] PR #212
7978 Changes with Apache 1.2b7
7980 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
7982 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
7984 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
7985 - replace protocol response numbers with symbols
7986 - save variant-list into main request notes
7987 - free allocated memory from subrequests
7988 - merge notes, headers_out and err_headers_out
7990 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
7991 "HTTP/#.# ###*" to be more lenient about what we accept.
7994 *) more proxy FTP bug fixes:
7995 - Changed send_dir() to remove user/passwd from displayed URL.
7996 - Changed login error messages to be more descriptive.
7997 - remove setting of SO_DEBUG socket option
7998 - Make ftp_getrc() more lenient about multiline responses,
7999 specifically, 230 responses which don't have continuation 230-
8000 on each line). These seem to be all NT FTP servers, and while
8001 perhaps questionable, they appear to be legal by RFC 959.
8002 - Add missing kill_timeout() after transfer to user completes.
8005 *) Fixed problem where a busy server could hang when restarting
8006 after being sent a SIGHUP due to child processes not exiting.
8009 *) Modify mod_include escaping so a '\' only signifies an escaped
8010 character if the next character is one that needs
8011 escaping. [Ben Laurie]
8013 *) Eliminated possible infinite loop in mod_imap when relative URLs are
8014 used with a 'base' directive that does not have a '/' in it.
8015 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
8017 *) Reduced the default timeout from 1200 seconds to 300, and the
8018 one in the sample configfile from 400 to 300. [Marc Slemko]
8020 *) Stop vbprintf from crashing if given a NULL string pointer;
8021 print (null) instead. [Ken Coar]
8023 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
8024 [Marc Slemko and Roy Fielding]
8026 *) Fixed problem with mod_cgi-generated internal redirects trying to
8027 read the request message-body twice. [Archie Cobbs and Roy Fielding]
8029 *) Reduced timeout on lingering close, removed possibility of a blocked
8030 read causing the child to hang, and stopped logging of errors if
8031 the socket is not connected (reset by client). [Roy Fielding]
8033 *) Rearranged main child loop to remove duplication of code in
8034 select/accept and keep-alive requests, fixed several bugs regarding
8035 checking scoreboard_image for exit indication and failure to
8036 account for all success conditions and trap all error conditions,
8037 prevented multiple flushes before closing the socket; close the entire
8038 socket buffer instead of just one descriptor, prevent logging of
8039 EPROTO and ECONNABORTED on platforms where supported, and generally
8040 improved readability. [Roy Fielding]
8042 *) Extensive performance improvements. Cleaned up inefficient use of
8043 auto initializers, multiple is_matchexp calls on a static string,
8044 and excessive merging of response_code_strings. [Dean Gaudet]
8046 *) Added double-buffering to mod_include to improve performance on
8047 server-side includes. [Marc Slemko]
8049 *) Several fixes for suexec wrapper. [Randy Terbush]
8050 - Make wrapper work for files on NFS filesystem.
8051 - Fix portability problem of MAXPATHLEN.
8052 - Fix array overrun problem in clean_env().
8053 - Fix allocation of PATH environment variable
8055 *) Removed extraneous blank line is description of mod_status chars.
8058 *) Logging of errors from the call_exec routine simply went nowhere,
8059 since the logfile fd has been closed, so now we send them to stderr.
8060 [Harald T. Alvestrand]
8062 *) Fixed core dump when DocumentRoot is a CGI.
8063 [Ben Laurie, reported by geddis@tesserae.com]
8065 *) Fixed potential file descriptor leak in mod_asis; updated it and
8066 http_core to use pfopen/pfclose instead of fopen/fclose.
8067 [Randy Terbush and Roy Fielding]
8069 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
8070 as the DEC Alpha which is 64-bit but uses 32-bit ints.
8071 [Dean Gaudet and Ken Coar]
8073 *) Return a 302 response code to the client when sending a redirect
8074 due to a missing trailing '/' on a directory instead of a 301; now
8075 it is cacheable. [Markus Gyger]
8077 *) Fix condition where, if a bad directive occurs in .htaccess, and
8078 sub_request() goes first to this directory, then log_reason() will
8079 SIGSEGV because it doesn't have initialized r->per_dir_config.
8080 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
8082 *) Fix handling of lang_index in is_variant_better(). This was
8083 causing problems which resulted in the server sending the
8084 wrong language document in some cases. [Petr Lampa]
8086 *) Remove free() from clean_env() in suexec wrapper. This was nuking
8087 the clean environment on some systems.
8089 *) Tweak byteserving code (e.g. serving PDF files) to work around
8090 bugs in Netscape Navigator and Microsoft Internet Explorer.
8091 Emit Content-Length header when sending multipart/byteranges.
8094 *) Port to HI-UX/WE2. [Nick Maclaren]
8096 *) Port to HP MPE operating system for HP 3000 machines
8097 [Mark Bixby <markb@cccd.edu>]
8099 *) Fixed bug which caused a segmentation fault if only one argument
8100 given to RLimit* directives. [Ed Korthof]
8102 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
8104 *) Improved buffered output to the client by delaying the flush decision
8105 until the BUFF code is actually about to read the next request.
8106 This fixes a problem introduced in 1.2b5 with clients that send
8107 an extra CRLF after a POST request. Also improved chunked output
8108 performance by combining writes using writev() and removing as
8109 many bflush() calls as possible. NOTE: Platforms without writev()
8110 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
8111 or Configure, unless we have already done so. [Dean Gaudet]
8113 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
8115 *) Fixed mod_info output corruption bug introduced by buffer overflow
8116 fixes. [Dean Gaudet]
8118 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
8119 for the special case of a 304 response. [Paul Sutton]
8121 *) Improved handling of TRACE method by bypassing normal method handling
8122 and header parsing routines; fixed Allow response to always allow TRACE.
8125 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
8127 *) Cleaned-up some of the generated HTML. [Ken Coar]
8129 Changes with Apache 1.2b6
8131 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
8133 *) Fix typo introduced in fix for potential infinite loop around
8134 accept() in child_main(). This change caused the rev to 1.2b6.
8135 1.2b5 was never a public beta.
8137 Changes with Apache 1.2b5
8139 *) Change KeepAlive semantics (On|Off instead of a number), add
8140 MaxKeepAliveRequests directive. [Alexei Kosut]
8142 *) Various NeXT compilation patches, as well as a change in
8143 regex/regcomp.c since that file also used a NEXT define.
8146 *) Allow * to terminate the end of a directory match in mod_dir.
8147 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
8149 *) Don't call can_exec() if suexec_enabled. Calling this requires
8150 scripts executed by the suexec wrapper to be world executable, which
8151 defeats one of the advantages of running the wrapper. [Randy Terbush]
8153 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
8156 *) Migration from sprintf() to snprintf() to avoid buffer
8157 overflows. [Marc Slemko]
8159 *) Provide portable snprintf() implementation (ap_snprintf)
8160 as well as *cvt family. [Jim Jagielski]
8162 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
8165 *) Remove mod_fastcgi.c from the distribution. This module appears
8166 to be maintained more through the Open Market channels and should
8167 continue to be easily available at http://www.fastcgi.com/
8169 *) Fixed bug in modules/Makefile that wouldn't allow building in more
8170 than one subdirectory (or cleaning, either). [Jeremy Laidman]
8172 *) mod_info assumed that the config files were relative to ServerRoot.
8175 *) CGI scripts called as an error document resulting from failed
8176 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
8178 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
8181 *) Properly check errno to prevent display of a directory index
8182 when server receives a long enough URL to confuse stat().
8185 *) Several security enhancements to suexec wrapper. It is _highly_
8186 recommended that previously installed versions of the wrapper
8187 be replaced with this version. [Randy Terbush, Jason Dour]
8189 - ~user execution now properly restricted to ~user's home
8190 directory and below.
8191 - execution restricted to UID/GID > 100
8192 - restrict passed environment to known variables
8193 - call setgid() before initgroups() (portability fix)
8194 - remove use of setenv() (portability fix)
8196 *) Add HTTP/1.0 response forcing. [Ben Laurie]
8198 *) Add access control via environment variables. [Ben Laurie]
8200 *) Add rflush() function. [Alexei Kosut]
8202 *) remove duplicate pcalloc() call in new_connection().
8204 *) Fix incorrect comparison which could allow number of children =
8205 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
8206 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
8208 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
8209 AIX PS/2, CONVEXOS. [Jim Jagielski]
8211 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
8212 It's more portable. [Martin Kraemer]
8214 *) Replace references to make in Makefile.tmpl with $(MAKE).
8217 *) Add ProxyBlock directive w/IP address caching. Add IP address
8218 caching to NoCache directive as well. ProxyBlock works with all
8219 handlers; NoCache now also works with FTP for anonymous logins.
8220 Still more code cleanup. [Chuck Murcko]
8222 *) Add "header parse" API hook [Ben Laurie]
8224 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
8226 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
8228 *) Correctly allow access and auth directives in <Files> sections in
8229 server config files. [Alexei Kosut]
8231 *) Fix bug with ServerPath that could cause certain files to be not
8232 found by the server. [Alexei Kosut]
8234 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
8235 double-quote from text and so that it properly checks for unsupported
8236 status codes using the new index_of_response interface. [Roy Fielding]
8238 *) Multiple fixes to the lingering_close code in order to avoid being
8239 interrupted by a stray timeout, to avoid lingering on a connection
8240 that has already been aborted or never really existed, to ensure that
8241 we stop lingering as soon as any error condition is received, and to
8242 prevent being stuck indefinitely if the read blocks. Also improves
8243 reporting of error conditions. [Marc Slemko and Roy Fielding]
8245 *) Fixed initialization of parameter structure for sigaction.
8246 [mgyger@itr.ch, Adrian Filipi-Martin]
8248 *) Fixed reinitializing the parameters before each call to accept and
8249 select, and removed potential for infinite loop in accept.
8250 [Roy Fielding, after useful PR from adrian@virginia.edu]
8252 *) Fixed condition where, if a child fails to fork, the scoreboard would
8253 continue to say SERVER_STARTING forever. Eventually, the main process
8254 would refuse to start new children because count_idle_servers() will
8255 count those SERVER_STARTING entries and will always report that there
8256 are enough idle servers. [Phillip Vandry]
8258 *) Fixed bug in bcwrite regarding failure to account for partial writes.
8259 Avoided calling bflush() when the client is pipelining requests.
8260 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
8262 *) Added description of "." mode in server-status [Jim Jagielski]
8264 Changes with Apache 1.2b4
8266 *) Fix possible race condition in accept_mutex_init() that
8267 could leave a small security hole open allowing files to be
8268 overwritten in cases where the server UID has write permissions.
8271 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
8273 *) Fix portablity problem in util_script where ARG_MAX may not be
8274 defined for some systems.
8276 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
8279 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
8280 style magic #! token for better script portability. [Garey Smiley]
8282 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
8283 execution for ~userdir CGI. [Jason Dour]
8285 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
8287 *) Fix month off by one in suexec wrapper logging.
8289 Changes with Apache 1.2b3:
8291 *) Fix error in mod_cgi which could cause resources not to be properly
8292 freed, or worse. [Dean Gaudet]
8294 *) Fix find_string() NULL pointer dereference. [Howard Fear]
8296 *) Add set_flag_slot() at the request of Dirk and others.
8299 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
8301 *) Add changes to improve the error message given for invalid
8302 ServerName parameters. [Dirk vanGulik]
8304 *) Add "Authoritative" directive for Auth modules that don't
8305 currently have it. This gives admin control to assign authoritative
8306 control to an authentication scheme and allow "fall through" for
8307 those authentication modules that aren't "Authoritative" thereby
8308 allowing multiple authentication mechanisms to be chained.
8311 *) Remove requirement for ResourceConfig/AccessConfig if not using
8312 the three config file layout. [Randy Terbush]
8314 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
8316 *) Changes to suexec wrapper to fix the following problems:
8317 1. symlinked homedirs will kill ~userdirs.
8318 2. initgroups() on Linux 2.0.x clobbers gr->grid.
8319 3. CGI command lines paramters problems
8320 4. pw-pwdir for "docroot check" still the httpd user's pw record.
8321 [Randy Terbush, Jason Dour]
8323 *) Change create_argv() to accept variable arguments. This fixes
8324 a problem where arguments were not getting passed to the CGI via
8325 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
8327 *) Collapse multiple slashes in path URLs to properly apply
8328 handlers defined by <Location>. [Alexei Kosut]
8330 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
8332 *) Improve the accuracy of request duration timings by setting
8333 r->request_time in read_request_line() instead of read_request().
8336 *) Reset timeout while reading via get_client_block() in mod_cgi.c
8337 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
8339 *) Add the ability to pass different Makefile.tmpl files to Configure
8340 using the -make flag. [Rob Hartill]
8342 *) Fix coredump triggered when sending a SIGHUP to the server caused
8343 by an assertion failure, in turn caused by an uninitialised field in a
8347 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
8348 PATH_INFO from previous versions of Apache (in certain situations,
8349 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
8350 [later removed in 1.2b11]
8352 *) Add rwrite() function to API to allow for sending strings of
8353 arbitrary length. [Doug MacEachern]
8355 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
8357 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
8358 NeXT. [Jim Jagielski]
8360 *) Removed recent modification to promote the status code on internal
8361 redirects, since the correct fix was to change the default log format
8362 in mod_log_config so that it outputs the original status. [Rob Hartill]
8364 Changes with Apache 1.2b2:
8366 *) Update set_signals() to use sigaction() for setting handlers.
8367 This appears to fix a re-entrant problem in the seg_fault()
8368 bus_error() handlers. [Randy Terbush]
8370 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
8372 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
8374 *) proxy_http.c bugfixes: [Chuck Murcko]
8375 1) fixes possible NULL pointer reference w/NoCache
8376 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
8377 host would cache nothing if it was in the local domain,
8378 and the local domain was in the NoCache list)
8379 3) Adds Host: header when not available
8380 4) Some code cleanup and clarification
8382 *) mod_include.c bugfixes:
8383 1) Fixed an ommission that caused include variables to not
8384 be parsed in config errmsg directives [Howard Fear]
8385 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
8386 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
8387 4) Allow backslash-escaping to all quoted text
8388 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
8389 5) Pass variable to command line if not set in XSSI's env
8392 *) Fix infinite loop when processing Content-language lines in
8393 type-map files. [Alexei Kosut]
8395 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
8397 *) Fixed problem in set_[user|group] that prevented CGI execution
8398 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
8400 *) Added PORTING information file. [Jim Jagielski]
8402 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
8404 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
8406 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
8407 USE_FCNTL_SERIALIZED_ACCEPT was intended.
8409 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
8410 which caused problems of systems where socket s_addr is >32bits.
8412 *) Added comment to explain (r->chunked = 1) side-effect in
8413 http_protocol.c [Roy Fielding]
8415 *) Replaced use of index() in mod_expires.c with more appropriate
8416 and portable isdigit() test. [Ben Laurie]
8418 *) Updated Configure for ...
8419 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
8420 *-dg-dgux* (bad pattern match)
8421 QNX (DEF_WANTHSREGEX=yes)
8422 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
8425 and added some user diagnostic info. [Ben Laurie]
8427 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
8428 for better portability. [Jim Jagielski]
8430 *) Updated helpers/GuessOS for ...
8431 SCO 5 (recognize minor releases)
8432 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
8433 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
8434 IRIX64 (-sgi-irix64)
8435 ULTRIX (-unknown-ultrix)
8436 SINIX (-whatever-sysv4)
8437 NCR Unix (-ncr-sysv4)
8438 and fixed something in helpers/PrintPath [Ben Laurie]
8440 Changes with Apache 1.2b1
8442 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
8444 Changes with Apache 1.1.1
8446 *) Fixed bug where Cookie module would make two entries in the
8447 logfile for each access [Mark Cox]
8449 *) Fixed bug where Redirect in .htaccess files would cause memory
8450 leak. [Nathan Neulinger]
8452 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
8454 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
8456 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
8458 Changes with Apache 1.1.0
8460 *) Bring NeXT support up to date. [Takaaki Matsumoto]

8464 *) Make virtual hosts default to main server keepalive parameters.
8465 [Alexei Kosut, Ben Laurie]
8467 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
8469 *) Fix missing address family for connect, also remove unreachable statement
8470 in mod_proxy. [Ben Laurie]
8472 *) mod_env now turned on by default in Configuration.tmpl.
8474 *) Bugs which were fixed:
8475 a) yet more mod_proxy bugs [Ben Laurie]
8476 b) CGI works again with inetd [Alexei Kosut]
8477 c) Leading colons were stripped from passwords [osm@interguide.com]
8478 d) Another fix to multi-method Limit problem [jk@tools.de]
8480 Changes with Apache 1.1b4
8482 *) r->bytes_sent variable restored. [Robert Thau]
8484 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
8486 *) More possibly unsecure programs removed from the support directory.
8488 *) More mod_auth_msql authentication improvements.
8490 *) VirtualHosts based on Host: headers no longer conflict with the
8493 *) OS/2 compatibility enhancements. [Gary Smiley]
8495 *) POST now allowed to directory index CGI scripts.
8497 *) Actions now work with files of the default type.
8499 *) Bugs which were fixed:
8500 a) more mod_proxy bugs
8501 b) early termination of inetd requests
8502 c) compile warnings on several systems
8503 d) problems when scripts stop reading output early
8505 Changes with Apache 1.1b3
8507 *) Much of cgi-bin and all of cgi-src has been removed, due to
8508 various security holes found and that we could no longer support
8511 *) The "Set-Cookie" header is now special-cased to not merge multiple
8512 instances, since certain popular browsers can not handle multiple
8513 Set-Cookie instructions in a single header. [Paul Sutton]
8515 *) rprintf() added to buffer code, occurrences of sprintf removed.
8518 *) CONNECT method for proxy module, which means tunneling SSL should work.
8519 (No crypto needed) Also a NoCache config directive.
8521 *) Several API additions: pstrndup(), table_unset() and get_token()
8522 functions now available to modules.
8524 *) mod_imap fixups, in particular Location: headers are now complete
8527 *) New "info" module which reports on installed module set through a
8528 special URL, a la mod_status.
8530 *) "ServerPath" directive added - allows for graceful transition
8531 for Host:-header-based virtual hosts.
8533 *) Anonymous authentication module improvements.
8535 *) MSQL authentication module improvements.
8537 *) Status module design improved - output now table-based. [Ben Laurie]
8539 *) htdigest utility included for use with digest authentication
8542 *) mod_negotiation: Accept values with wildcards to be treated with
8543 less priority than those without wildcards at the same quality
8544 value. [Alexei Kosut]
8546 *) Bugs which were fixed:
8547 a) numerous mod_proxy bugs
8548 b) CGI early-termination bug [Ben Laurie]
8549 c) Keepalives not working with virtual hosts
8550 d) RefererIgnore problems
8551 e) closing fd's twice in mod_include (causing core dumps on
8552 Linux and elsewhere).
8554 Changes with Apache 1.1b2
8557 a) core dumps in mod_digest
8558 b) truncated hostnames/ip address in the logs
8559 c) relative URL's in mod_imap map files
8561 Changes with Apache 1.1b1

8565 Changes with Apache 1.0.3
8567 *) Internal redirects which occur in mod_dir.c now preserve the
8568 query portion of a request (the bit after the question mark).
8571 *) Escape active characters '<', '>' and '&' in html output in
8572 directory listings, error messages and redirection links.
8575 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
8577 *) Fix for POSIX compliance in waiting for processes in alloc.c.
8580 *) setsockopt no longer takes a const declared argument [Martijn Koster]
8582 *) Reset timeout timer after each successful fwrite() to the network.
8583 This patch adds a reset_timeout() procedure that is called by
8584 send_fd() to reset the timeout ever time data is written to the net.
8587 *) timeout() signal handler now checks for SIGPIPE and reports
8588 lost connections in a more user friendly way. [Rob Hartill]
8590 *) Location of the "scoreboard" file which used to live in /tmp is
8591 now configurable (for OSes that can't use mmap) via ScoreBoardFile
8592 which works similar to PidFile (in httpd.conf) [Rob Hartill]
8594 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
8596 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
8597 which caused a SEGV with cookies enabled
8599 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
8602 *) Log the UNIX textual error returned by some system calls, in
8603 particular errors from accept() [David Robinson]
8605 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
8607 Changes with Apache 1.0.2
8609 *) patch to get Apache compiled on UnixWare 2.x, recommended as
8610 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
8612 *) Fix get_basic_auth_pw() to set the auth_type of the request.
8615 *) past changes to http_config.c to only use the
8616 setrlimit function on systems defining RLIMIT_NOFILE
8617 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
8618 for SUNOS and prototypes the needed functions.
8620 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
8623 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
8625 *) Merge multiple headers from CGI scripts instead of taking last
8626 one. [David Robinson]
8628 *) Add support for SCO 5. [Ben Laurie]
8630 Changes with Apache 1.0.1
8632 *) Silence mod_log_referer and mod_log_agent if not configured
8635 *) Recursive includes can occur if the client supplies PATH_INFO data
8636 and the server provider uses relative links; as file.html
8637 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
8639 *) The replacement for initgroups() did not call {set,end}grent(). This
8640 had two implications: if anything else used getgrent(), then
8641 initgroups() would fail, and it was consuming a file descriptor.
8644 *) On heavily loaded servers it was possible for the scoreboard to get
8645 out of sync with reality, as a result of a race condition.
8646 The observed symptoms are far more Apaches running than should
8647 be, and heavy system loads, generally followed by catastrophic
8648 system failure. [Ben Laurie]
8650 *) Fix typo in license. [David Robinson]
8652 Changes with Apache 1.0.0 23 Nov 1995
8654 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
8656 Changes with Apache 0.8.16 05 Nov 1995
8658 *) New man page for 'httpd' added to support directory [David Robinson]
8660 *) .htgroup files can have more than one line giving members for a
8661 given group (each must have the group name in front), for NCSA
8662 back-compatibility [Robert Thau]
8664 *) Mutual exclusion around accept() is on by default for SVR4 systems
8665 generally, since they generally can't handle multiple processes in
8666 accept() on the same socket. This should cure flaky behavior on
8667 a lot of those systems. [David Robinson]
8669 *) AddType, AddEncoding, and AddLanguage directives take multiple
8670 extensions on a single command line [David Robinson]
8672 *) UserDir can be disabled for a given virtual host by saying
8673 "UserDir disabled" in the <VirtualHost> section --- it was a bug
8674 that this didn't work. [David Robinson]
8676 *) Compiles on QNX [Ben Laurie]
8678 *) Corrected parsing of ctime time format [David Robinson]
8680 *) httpd does a perror() before exiting if it can't log its pid
8681 to the PidFile, to make diagnosing the error a bit easier.
8684 *) <!--#include file="..."--> can no longer include files in the
8685 parent directory, for NCSA back-compatibility. [David Robinson]
8687 *) '~' is *not* escaped in URIs generated for directory listings
8690 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
8692 *) Fixed bug involving handling URIs with escaped %-characters
8693 in redirects [David Robinson]
8695 Changes with Apache 0.8.15 14 Oct 1995
8697 *) Switched to new, simpler license
8699 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
8701 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
8703 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
8705 *) Correctly handles internal redirects to files with names containing '%'
8708 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
8710 *) Use geteuid() rather than getuid() to see if we have root privilege,
8711 so that server correctly resets privilege if run setuid root. [Andrew
8714 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
8717 *) Fix relative URLs in imagemap files [Randy Terbush]
8719 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
8722 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
8723 entries all name the same one. [David Robinson]
8725 *) Fix directory listings with filenames containing unusual characters
8728 *) Better URI-escaping for generated URIs in directories with filenames
8729 containing unusual characters [Ben Laurie]
8731 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
8733 *) Unblock alarms on error return from spawn_child() [David Robinson]
8735 *) Sample Config files have extra note for SCO users [Ben Laurie]
8737 *) Configuration has note for HP-UX users [Rob Hartill]
8739 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
8741 *) Nuked bogus #define in httpd.h [David Robinson]
8743 *) Better test for whether a system has setrlimit() [David Robinson]
8745 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
8747 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
8750 Changes with Apache 0.8.14 19 Sep 1995
8752 *) Compiles on SCO ODT 3.0 [Ben Laurie]
8754 *) AddDescription works (better) [Ben Laurie]
8756 *) Leaves an intelligible error diagnostic when it can't set group
8757 privileges on standalone startup [Andrew Wilson]
8759 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
8760 that machine, which claims to be BSD but does not support RLIMIT.
8763 *) gcc -Wall no longer complains about an unused variable when util.c
8764 is compiled with -DMINIMAL_DNS [Andrew Wilson]
8766 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
8768 Changes with Apache 0.8.13 07 Sep 1995
8770 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
8772 *) Have built-in imagemap code recognize & honor Point directive [James
8775 *) Generate cleaner directory listings in directories with a mix of
8776 long and short filenames [Rob Hartill]
8778 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
8780 *) Properly default ServerName for virtual servers [Robert Thau]
8782 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
8783 Paul Richards and a cast of thousands...]
8785 *) On self-identified BSD systems (we don't try to guess any more),
8786 allocate a few extra file descriptors per virtual host with setrlimit,
8787 if we can, to avoid running out. [Randy Terbush]
8789 *) Write 22-character lock file name into buffer with enough space
8790 on startup [Konstantin Olchanski]
8792 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
8795 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
8797 *) Suppress -Wall warning by initializing variable in negotiation code
8798 [Tobias Weingartner]
8800 Changes with Apache 0.8.12 31 Aug 1995
8802 *) Doesn't pause three seconds after including a CGI script which is
8803 too slow to die off (this is done by not even trying to kill off
8804 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
8805 after the entire document has been processed). [Robert Thau]
8807 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
8809 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
8811 *) Allows .htaccess files to override <Directory> sections naming the
8812 same directory [David Robinson]
8814 *) Removed an efficiency hack in sub_req_lookup_uri which was
8815 causing certain extremely marginal cases (e.g., ScriptAlias of a
8816 *particular* index.html file) to fail. [David Robinson]
8818 *) Doesn't log an error when the requested URI requires
8819 authentication, but no auth header line was supplied by the
8820 client; this is a normal condition (the client doesn't no auth is
8821 needed here yet). [Robert Thau]
8823 *) Behaves more sanely when the name server loses its mind [Sean Welch]
8825 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
8827 *) RFC931 code no longer passes out name of prior clients on current
8828 requests if the current request came from a server that doesn't
8829 do RFC931. [David Robinson]
8831 *) Configuration script accepts "Module" lines with trailing whitespace.
8834 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
8836 *) Cleaned up comments in mod_cgi.c [Robert Thau]
8838 Changes with Apache 0.8.11 24 Aug 1995
8840 *) Wildcard <Directory> specifications work. [Robert Thau]
8842 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
8844 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
8845 the file being requested itself, in addition to the directories leading
8846 up to it. [Robert Thau]
8848 *) Logs access failures due to symlink checks or invalid client address
8849 in the error log [Roy Fielding, Robert Thau]
8851 *) Symlink checks deal correctly with systems where lstat of
8852 "/path/to/some/link/" follows the link. [Thau, Fielding]
8854 *) Doesn't reset DirectoryIndex to 'index.html' when
8855 other directory options are set in a .htaccess file. [Robert Thau]
8857 *) Clarified init code and nuked bogus warning in mod_access.c
8860 *) Corrected several directives in sample srm.conf
8861 --- includes corrections to directory indexing icon-related directives
8862 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
8863 icons for encodings right, and turning on AddEncoding by default).
8866 *) Corrected descriptions of args to AddIcon and AddAlt in command table
8869 *) INSTALL & README mention "contributed modules" directory [Brian
8872 *) Fixed English in the license language... "for for" --> "for".
8875 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
8876 mod_alias.c, merging it almost completely with handling of Alias, and
8877 adding a 'notes' field to the request_rec which allows the CGI module
8878 to discover whether the Alias module has put this request through
8879 ScriptAlias (which it needs to know for back-compatibility, as the old
8880 NCSA code did not check Options ExecCGI in ScriptAlias directories).
8883 Changes with Apache 0.8.10 18 Aug 1995
8885 *) AllowOverride applies to the named directory, and not just
8886 subdirectories. [David Robinson]
8888 *) Do locking for accept() exclusion (on systems that need it)
8889 using a special file created for the purpose in /usr/tmp, and
8890 not the error log; using the error log causes real problems
8891 if it's NFS-mounted; this is known to be the cause of a whole
8892 lot of "server hang" problems with Solaris. [David Robinson;
8893 thanks to Merten Schumann for help diagnosing the problem].
8895 Changes with Apache 0.8.9 12 Aug 1995
8897 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
8899 *) Nested includes see environment variables of the including document,
8900 for NCSA bug-compatibility (some sites have standard footer includes
8901 which try to print out the last-modified date). [Eric Hagberg/Robert
8904 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
8905 URI as a CGI script, even if it would have been treated as something
8906 else if requested directly, for NCSA back-compatibility. (Note that
8907 this means that people who know the name of the script can see the
8908 code just by asking for it). [Robert Thau]
8910 *) New version of dbmmanage script included in support directory as
8913 *) Check if scoreboard file couldn't be opened, and say so, rather
8914 then going insane [David Robinson]
8916 *) POST to CGI works on A/UX [Jim Jagielski]
8918 *) AddIcon and AddAlt commands work properly [Rob Hartill]
8920 *) NCSA server push works properly --- the Arena bug compatibility
8921 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
8922 if you still want the workaround). [Rob Hartill]
8924 *) If client didn't submit any Accept-encodings, ignore encodings in
8925 content negotiation. (NB this will all have to be reworked anyway
8926 for the new HTTP draft). [Florent Guillaume]
8928 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
8930 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
8932 *) Give Redirect priority over Alias, for NCSA bug compatibility
8935 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
8936 paralleling earlier bug fix for CGI [David Robinson]
8938 *) If DBM auth is improperly configured, report a server error and don't
8941 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
8942 it seems to work well enough without it (even in a 10 hits/sec
8943 workout), and the overhead for the locking under A/UX is
8944 alarmingly high (though it is very low on other systems).
8945 [Eric Hagberg, Jim Jagielski]
8947 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
8949 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
8950 Behlendorf/Eric Hagberg]
8952 *) More improvements to default Configuration for A/UX [Jim Jagielski]
8954 *) Compiles clean on NEXT [Rob Hartill]
8956 *) Compiles clean on SGI [Robert Thau]
8958 Changes with Apache 0.8.8 08 Aug 1995
8960 *) SunOS library prototypes now never included unless explicitly
8961 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
8962 people using GNU libc on SunOS are screwed by prototypes for the
8965 (Those who wish to compile clean with gcc -Wall on a standard
8966 SunOS setup need the prototypes, and may obtain them using
8967 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
8968 with nonstandard libraries are presumably competent to make their
8971 *) Strips trailing '/' characters off both args to the Alias command,
8972 to make 'Alias /foo/ /bar/' work.
8974 Changes with Apache 0.8.7 03 Aug 1995
8976 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
8977 [reported by David Robinson]
8979 *) Compiles clean on OSF/1 [David Robinson]
8981 *) Added some of the more recent significant changes (AddLanguage stuff,
8982 experimental LogFormat support) to CHANGES file in distribution root
8985 Changes with Apache 0.8.6 02 Aug 1995
8987 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
8988 (If you actually wanted a conditional GET which bypassed the cache, you
8989 couldn't get it). [Reported by Roy Fielding]
8991 *) Properly terminate headers on '304 Not Modified' replies to conditional
8992 GETs --- no browser we can find cares much, but the CERN proxy chokes.
8993 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
8995 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
8997 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
8998 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
8999 and older versions don't set the __SUNPRO_C preprocessor variable). On
9000 all other systems, these are never used anyway. [Reported by Mark Cox].
9002 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
9004 Changes with Apache 0.8.5 01 Aug 1995
9006 *) Added last-minute configurable log experiment, as optional module
9008 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
9009 properly. (One-line fix to http_protocol.c).
9011 *) Work around bogus behavior when reloading from Netscape.
9012 It's Netscape's bug --- for some reason they expect a request with
9013 If-modified-since: to not function as a conditional GET if it also
9014 comes with Pragma: no-cache, which is way out of line with the HTTP
9015 spec (according to Roy Fielding, the redactor).
9017 *) Added parameter to set maximum number of server processes.
9019 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
9022 *) IdentityCheck bugfix [Chuck Murcko].
9024 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
9026 *) More sample config file corrections; add extension to AddType for
9027 *.asis, move AddType generic description to its proper place, and
9028 fix miscellaneous typos. [ Alexei Kosut ]
9030 *) Deleted the *other* reference to the regents from the Berkeley
9031 legal disclaimer (everyplace).
9033 *) Nuked Shambhala name from src/README; had already cleaned it out
9036 Changes with Apache 0.8.4
9038 *) Changes to server-pool management parms --- renamed current
9039 StartServers to MinSpareServers, created separate StartServers
9040 parameter which means what it says, and renamed MaxServers to
9041 MaxSpareServers (though the old name still works, for NCSA 1.4
9042 back-compatibility). The old names were generally regarded as
9043 too confusing. Also altered "docs" in sample config files.
9045 *) More improvements to default config files ---
9046 sample directives (commented out) for XBitHack, BindAddress,
9047 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
9048 defaults, AddTypes for send-as-is and imagemap magic types, and
9049 improvements to samples for DirectoryIndex [Alexei Kosut]
9051 *) Yet more improvements to default config files --- changes to
9052 Alexei's sample AddLanguage directives, and sample LanguagePriority
9053 [ Florent Guillaume ]
9055 *) Set config file locations properly if not set in httpd.conf
9058 *) Don't escape URIs in internal redirects multiple times; don't
9059 do that when translating PATH_INFO to PATH_TRANSLATED either.
9062 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
9064 Changes with Apache 0.8.3
9066 *) Edited distribution README to *briefly* summarize installation
9067 procedures, and give a pointer to the INSTALL file in the src/
9070 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
9071 recent NCSA distributions.
9073 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
9074 exist for the same directory, use both and don't segfault. [Reported
9077 *) Proper makefile dependencies [David Robinson]
9079 *) Note (re)starts in error log --- reported by Rob Hartill.
9081 *) Only call no2slash() after get_path_info() has been done, to
9082 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
9083 reported by Andrew Wilson, though this one is probably a real bug]
9085 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
9086 dump core when Referer is not supplied. [Randy Terbush]
9088 *) Lightly edited sample config files to refer people to our documentation
9089 instead of NCSA's, and to list Rob McCool as *original* author (also
9090 deleted his old, and no doubt non-functional email address). Would be
9091 nice to have examples of new features...
9093 Changes with Apache 0.8.2 19 Jul 1995
9095 *) Added AddLanuage code [Florent Guillaume]
9097 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
9099 *) All sorts of problems when MultiViews finds a directory. It would
9100 be nice if mod_dir.c was robust enough to handle that, but for now,
9101 just punt. [reported by Brian Behlendorf]
9103 *) Wait for all children on restart, to make sure that the old socket
9104 is gone and we can reopen it. [reported by Randy Terbush]
9106 *) Imagemap module is enabled in default Configuration
9108 *) RefererLog and UserAgentLog modules properly default the logfile
9111 *) Mark Cox's mod_cookies added to the distribution as an optional
9112 module (commented out in the default Configuration, and noted as
9113 an experiment, along with mod_dld). [Mark Cox]
9115 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
9117 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
9119 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
9121 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
9124 Changes with Apache 0.8.1
9126 *) New imagemap module [Randy Terbush]
9128 *) Replacement referer log module with NCSA-compatible RefererIgnore
9129 [Matthew Gray again]
9131 *) Don't mung directory listings with very long filenames.
9134 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
9136 *) New config script. See INSTALL for info. [Robert Thau]
9138 *) Scoreboard mechanism for regulating the number of extant server
9139 processes. MaxServers and StartServers defaults are the same as
9140 for NCSA, but the meanings are slightly different. (Actually,
9141 I should probably lower the MaxServers default to 10).
9143 Before asking for a new connection, each server process checks
9144 the number of other servers which are also waiting for a
9145 connection. If there are more than MaxServers, it quietly dies
9146 off. Conversely, every second, the root, or caretaker, process
9147 looks to see how many servers are waiting for a new connection;
9148 if there are fewer than StartServers, it starts a new one. This
9149 does not depend on the number of server processes already extant.
9150 The accounting is arranged through a "scoreboard" file, named
9151 /tmp/htstatus.*, on which each process has an independent file
9152 descriptor (they need to seek without interference).
9154 The end effect is that MaxServers is the maximum number of
9155 servers on an *inactive* server machine, but more will be forked
9156 off to handle unusually heavy loads (or unusually slow clients);
9157 these will die off when they are no longer needed --- without
9158 reverting to the overhead of full forking operation. There is a
9159 hard maximum of 150 server processes compiled in, largely to
9160 avoid forking out of control and dragging the machine down.
9161 (This is arguably too high).
9163 In my server endurance tests, this mechanism did not appear to
9164 impose any significant overhead, even after I forced it to put the
9165 scoreboard file on a normal filesystem (which might have more
9166 overhead than tmpfs). [Robert Thau]
9168 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
9171 *) Read .htaccess files even in directory with <Directory> section.
9172 (Former incompatibility noted on mailing list, now fixed). [Robert
9175 *) "HEAD /" gives the client a "Bad Request" error message, rather
9176 than trying to send no body *and* no headers. [Cliff Skolnick].
9178 *) Don't produce double error reports for some very obscure cases
9179 mainly involving auth configuration (the "all modules decline to
9180 handle" case which is a sure sign of a server bug in most cases,
9181 but also happens when authentication is badly misconfigured).
9184 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
9185 it's *for*, and this sort of thing really shouldn't be cluttering
9186 up the Makefile). [Robert Thau]
9188 *) Incidental code cleanups in http_main.c --- stop dragging
9189 sa_client around; just declare it where used. [Robert Thau]
9191 *) Another acc-related fix. (It doesn't like const char
9192 in some places...). [Mark Cox]
9194 Changes with Shambhala 0.6.1 13 Jul 1995
9196 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
9197 Also, fixed auth typo in http_protocol.c unmasked by this fix.
9199 *) Compiles clean with acc on SunOS [Paul Sutton]
9201 *) Reordered modules in modules.c so that Redirect takes priority
9202 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
9203 believe it or not, he has an actual site with a ScriptAlias and
9204 a Redirect declared for the *exact same directory*. Even *my*
9205 compatibility fetish wouldn't motivate me to fix this if the fix
9206 required any effort, but it doesn't, so what the hey.
9208 *) Fixed to properly default several server_rec fields for virtual
9209 servers from the corresponding fields in the main server_rec.
9210 [Cliff Skolnick --- 'port' was a particular irritant].
9212 *) No longer kills off nph- child processes before they are
9213 finished sending output. [Matthew Gray]
9215 Changes with Shambhala 0.6.0 10 Jul 1995
9217 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
9218 the connection to the client in an "aborted" state, but otherwise
9219 allow whatever handlers are running to clean up. hard_timeout()s
9220 abort the request in progress completely; anything not tied to some
9221 resource pool cleanup will leak. They're still around because I
9222 haven't yet come up with a more elegant way of handling
9223 timeouts when talking to something that isn't the client. The
9224 default_handler and the dir_handler now use soft timeouts, largely
9225 so I can test the feature. [Robert Thau]
9227 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
9228 the case of log handlers dying prematurely is probably handled VERY
9229 gracelessly at this point, and if the logger stops reading input,
9230 the server will hang. (It is known to correctly restart the
9231 logging process on server restart; this is (should be!) going through
9232 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
9233 script). [Robert Thau]
9235 *) asis files supported (new module). [Robert Thau]
9237 *) IdentityCheck code is compiled in, but has not been tested. (I
9238 don't know anyone who runs identd). [Robert Thau]
9240 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
9241 came in with the request, for NCSA bug-compatibility. [Robert Thau]
9243 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
9245 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
9246 as timeouts are not in scope. [Robert Thau]
9248 *) quoted-string args in config files now handled correctly (doesn't drop
9249 the last character). [Robert Thau; reported by Randy Terbush]
9251 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
9252 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
9254 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
9255 default default type); the former default default behavior when all
9256 type-checkers defaulted had been a core dump. [Paul Sutton]
9258 *) Copy filenames out of the struct dirent when indexing
9259 directories. (On Linux, readdir() returns a pointer to the same
9260 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
9262 Changes with Shambhala 0.5.3 [not released]
9264 *) Default response handler notes "file not found" in the error log,
9265 if the file was not found. [Cliff Skolnick].
9267 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
9268 code no longer sets up bogus PATH_INFO which fakes out the directory
9269 handler). [Cliff Skolnick]
9271 Changes with Shambhala 0.5.2 06 Jul 1995
9273 *) Changes to http_main.c --- root server no longer plays silly
9274 games with SIGCHLD, and so now detects and replaces dying
9275 children. Child processes just die on SIGTERM, without taking
9276 the whole process group with them. Potential problem --- if any
9277 child process refuses to die, we hang in restart.
9278 MaxRequestsPerChild may still not work, but it certainly works
9279 better than it did before this! [Robert Thau]
9281 *) mod_dir.c bug fixes: ReadmeName and HeaderName
9282 work (or work better, at least); over-long description lines
9283 properly terminated. [Mark Cox]
9285 *) http_request.c now calls unescape_url() more places where it
9286 should [Paul Sutton].
9288 *) More directory handling bugs (reported by Cox)
9289 Parent Directory link is now set correctly. [Robert Thau]
9291 Changes with Shambhala 0.5.1 04 Jul 1995
9293 *) Generalized cleanup interface in alloc.c --- any function can be
9294 registered with alloc.c as a cleanup for a resource pool;
9295 tracking of files and file descriptors has been reimplemented in
9296 terms of this interface, so I can give it some sort of a test.
9299 *) More changes in alloc.c --- new cleanup_for_exec() function,
9300 which tracks down and closes all file descriptors which have been
9301 registered with the alloc.c machinery before the server exec()s a
9302 child process for CGI or <!--#exec-->. CGI children now get
9303 started with exactly three file descriptors open. Hopefully,
9304 this cures the problem Rob H. was having with overly persistent
9305 CGI connections. [Robert Thau]
9307 *) Mutual exclusion around the accept() in child_main() --- this is
9308 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
9309 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
9310 This uses fcntl(F_SETLK,...) on the error log descriptor because
9311 flock() on that descriptor won't work on systems which have BSD
9312 flock() semantics, including (I think) Linux 1.3 and Solaris.
9314 This does work on SunOS (when the server is idle, only one
9315 process in the pool is waiting on accept()); it *ought* to work
9316 on the other systems. [Robert Thau]
9318 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
9320 *) sizeof(*sa_client) bugfix from [Rob Hartill]
9322 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
9324 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
9325 be unnecessary if I go to the revised timeout-handling scheme).
9328 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
9329 string) even if none came in with the request. [Robert Thau]
9331 *) CHANGES file added to distribution ;-).
9333 Changes with Shambhala 0.4.5
9335 *) mod_dld --- early dynamic loading support [rst]
9336 *) Add wildcard content handlers for XBITHACK; default_hander now
9337 invoked with that mechanism (as a handler hanging off mod_core) [rst]
9338 *) XBITHACK supported as a wildcard content-handler, and
9339 configurable at run-time (not just at compile time, as in the
9340 "patchy server" releases) [rst]
9342 Changes with Shambhala 0.4.4 30 Jun 1995
9344 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
9345 *) Handle Addtype x/y .z [rst, reported by Cox]
9347 Changes with Shambhala 0.4.3
9349 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
9350 synonymous [rst, terbush]
9352 Changes with Shambhala 0.4.1 28 Jun 1995
9354 *) First-cut virtual host implementation; some refit in the config
9355 reading code, and log management, was necessary to support this [rst]
9356 *) Sub-pool machinery, originally added to avoid excessive storage
9357 allocation on listings of large directories (which turned out to
9358 be the problem that the 0.3 storage accounting was added to
9359 find). Subrequests and mod_dir changed to use subpools. [rst]
9360 *) More memory debugging --- free list consistency checks. [rst]
9361 *) Added err_headers to request_rec, with support elsewhere [rst]
9362 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
9364 Changes with Shambhala 0.3 19 Jun 1995
9366 *) Switch ONE_PROCESS to a runtime command-line option (-X)
9367 *) Don't compile in mod_ai_backcompat by default
9368 *) Switch name of server from Apache to Shambhala in Makefile
9369 *) Add some accounting routines to track memory usage in the pools,
9372 Changes with Shambhala 0.2
9374 *) Set DOCUMENT_ROOT CGI variable
9375 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
9376 *) Add critical section protection to handling of cleanup structures
9378 *) Significant code reorg within the server core to group related
9379 functions together [rst]
9380 *) Correctly handle clients that hang up before sending any request
9382 *) Replace dying child processes. [rst]
9384 Changes with Shambhala 0.1 12 Jun 1995
9386 Major rewrite of the pre-existing "patchy server" codebase, by
9387 Robert Thau (rst). Significant portions of the server code, such
9388 as configuration-file handling and HTTP authentication support,
9389 were ripped out and rewritten from scratch. Code that was not
9390 completely rewritten was significantly altered.
9392 Major changes with this release include:
9394 *) Introduction of the module API; in request handling, the central
9395 machinery just dispatches to various modules, which actually do
9396 most of the work. Configuration handling is similar --- modules
9397 declare their own commands, and the central machinery just
9400 API features from shambhala/0.1 were substantially unchanged in
9401 Apache 1.0 and 1.1. (1.0 API features not yet present in this
9402 release, such as wildcard handlers and subpools, were added in
9403 subsequent Shambhala releases, and were also generally rst's
9406 *) This release included the following modules:
9408 mod_access (access control --- allow and deny directives),
9409 mod_alias (Alias and Redirect commands),
9410 mod_auth (straight HTTP authentication, based on flat-files)
9411 mod_auth_dbm (same, with dbm files)
9412 mod_cgi (CGI scripts and, in this release, ScriptAlias)
9413 mod_common_log (CLF access logs; later renamed mod_log_common)
9414 mod_dir (directory indexing)
9415 mod_include (server-side includes)
9416 mod_mime (AddType directives)
9417 mod_negotiation (content negotiation)
9418 mod_userdir (support for users' public_html directories)
9420 It also included a mod_ai_backcompat, which was a private hack
9421 for back-compatibility with rst's own AI-lab servers.
9423 All of these modules were substantially complete, and functional
9424 or nearly so (a few, which implemented features not in use at
9425 Thau's site, required patches of a few lines).
9427 *) sub-request machinery, to allow modules to determine how other
9428 modules would assign MIME types to a given file, or optionally
9429 serve its content (this is heavily used by mod_dir, mod_include
9430 and mod_negotiation).
9432 *) Resource pool system for keeping track of memory allocated and
9433 files opened in service of a particular request. Much of the
9434 code in the modules (when they weren't rewrites) was adjusted to
9435 replace a pervasive convention of using fixed-size buffers on
9436 the stack with an equally pervasive convention of using memory
9437 allocated with palloc().
9439 *) Reorganization of data structures associated with a given
9440 request to eliminate use of global variables and the troublesome
9441 unmunge_name function (used in NCSA and early Apache releases to
9442 attempt to determine the URI which mapped to a given filename
9443 --- a difficult proposition, given that it is easy to produce
9444 setups in which multiple URIs map to the same file).
9446 *) Source files renamed and rearranged
9448 *) Very simple pre-forking behavior --- parent process forked off a
9449 fixed number of children, and then just waited for SIGHUP.
9451 *) Other more minor changes too numerous to list.
9453 This release included modified versions of a lot of code from the
9454 Apache 0.6.4 public release, plus an early pre-forking patch
9455 codeveloped by Robert Thau and Rob Hartill.
9457 Changes with Apache 0.7.3 20 Jun 1995
9459 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
9460 were incorporated by Rob Hartill on the main branch while Robert Thau
9461 worked on the Shambhala rewrite above. Most were merged into the
9462 Shambala architecture after Apache 0.8.0.
9464 Changes with Apache 0.6.4 13 May 1995
9466 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
9469 Changes with Apache 0.5.1 10 Apr 1995
9471 Changes with Apache 0.4 02 Apr 1995
9473 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
9476 Changes with Apache 0.3 24 Mar 1995
9478 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
9481 Changes with Apache 0.2 18 Mar 1995
9483 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
9484 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
9485 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
