1 Changes with Apache 2.0.18-dev
3 *) Create Files, and thus MMAPs, out of the request pool, not the
4 connection pool. This solves a small resource leak that had us
5 not closing files until a connection was closed. In order to do
6 this, at the end of the core_output_filter, we loop through the
7 brigade and convert any data we have into a single HEAP bucket
8 that we know will survive clearing the request_rec.
9 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
12 *) Completely revamp configure so that it preserves the standard make
13 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
14 the configure additions to EXTRA_* variables. Also, allow the user
15 to specify NOTEST_* values for all of the above, which eliminates the
16 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
17 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
18 avoid pointless duplications. Fix the order in which flags are given
19 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
20 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
21 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
22 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
24 *) Get mod_tls to compile/work better on Windows. PR #7612
25 [Bernhard Schrenk <b.schrenk@improx.com>]
27 *) Fix shutdown/restart hangs in the threaded MPM.
28 [Jeff Trawick, Greg Ames, Ryan Bloom]
30 *) Removed the keptalive boolean from conn_rec because it is now only
31 used by a single routine and can be replaced by a local variable.
32 [Greg Stein, Ryan Bloom, Roy Fielding]
34 *) Patch prefork to put enough of the signal processing back in so that
35 signals are all handled properly now. The previous patch fixed the
36 deadlock race condition, but broke the user directed signal handling.
37 This fixes it to work the way it did before my previous prefork patch
38 (primarily, SIGTERM is now working).
40 *) Change how input filters decide how much data is returned to the
41 higher filter. We used to use a field in the conn_rec, with this
42 change, we use an argument to ap_get_brigade to determine how much
43 data is retrieved. [Ryan Bloom]
45 *) Fix seg fault at start-up introduced by Ryan's change to enable
46 modules to specify their own logging tags. mod_log_config
47 registers an optional function, ap_register_log_handler().
48 ap_register_log_handler() was being called by http_core before
49 the directive hash table was created. This patch creates the
50 directive hash table before ap_register_log_handler() is
51 registered as an optional function.
52 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
54 *) Add ap_set_int_slot() function
55 [John K. Sterling <sterling@covalent.net>]
57 *) Under certain circumstances, Apache did not supply the
58 right response headers when requiring authentication.
59 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
60 (This is a port of the change that went into Apache 1.3.19.)
62 *) Allow modules to specify their own logging tags. This basically
63 allows a module to tell mod_log_config that when %x is encountered
64 a specific function should be called. Currently, x can be any single
65 character. It may be more useful to make this a string at some point.
68 Changes with Apache 2.0.17
70 *) If a higher-level filter handles the the byterange aspects of a
71 request, then the byterange filter should not try to redo the
72 work. The most common case of this happening, is a byterange
73 request going through the proxy, and the origin server handles
74 the byterange request. The proxy should ignore it.
75 [Graham Leggett <minfrin@sharp.fm>]
77 *) Changed the threaded mpm to have child_main join to each of the
78 worker threads to make sure the kids are all gone before child_main
79 exits after a signal (cleanup from perform_idle_server_maintenance).
80 This is an extension of Ryans recent commit to make the child_main
83 *) Add more options to the ap_mpm_query function. This also allows MPMs to
84 report if their threads are dynamic or static. Finally, this also
85 implements a new API, ap_show_mpm, which returns the MPM that was
86 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
88 *) Do not install the binaries from the support directory twice.
89 [jun-ichiro hagino <itojun@iijlab.net>]
91 *) The ap_f* functions should flush data to the filter that is passed
92 in, not the the filter after the one passed in.
93 [Ryan Morgan <rmorgan@covalent.net>]
95 *) Make ab work again by changing its native types to apr types and formats.
96 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
98 *) Move the byterange filter and all of the supporting functions back
99 to the HTTP module. The byterange filter turned out to be very
100 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
102 *) Make clean, distclean, and extraclean consistently according to the
103 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
105 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
106 This may have been causing problems stopping processes in the threaded
109 *) Fix content-length in mod_negotiation to a long int representation.
112 *) Remove BindAddress from the default config file.
113 [giles@nemeton.com.au]
115 *) Allow module authors to add a module to their Apache build using
116 --with-module, without re-running buildconf. The syntax is:
117 --with-module=module_type:/path/to/module.c
118 The configure script will copy the module.c file to
119 modules/module_type, and it will be added to the relevant Makefiles.
120 currently, this only works for static modules. [Ryan Bloom]
122 *) Changes required to make prefork clean up idle children properly.
123 There was a window during which a starting worker deadlocks when
124 an idle cleanup arrives before it completes init. Apache then keeps
125 trying to cleanup the same deadlocked worker forever (until higher
126 pids come along, but it still will never reduce below the deadlocked
127 pid). Thus the number of children would not reduce to the correct
128 idle level. [Paul J. Reder]
130 Changes with Apache 2.0.16
132 *) Change the default installation directory to /usr/local/apache2,
133 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
135 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
138 *) Get MaxRequestsPerChild working with the Windows MPM.
141 *) Make generic hooks to work, with mod_generic_hook_import/export
142 experimental modules. [Ben Laurie, Will Rowe]
144 *) Fix segfaults for configuration file syntax errors such as
145 "<Directory>" followed by "</Directory" and
146 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
148 *) Cleanup the --enable-layout option of configure. This makes
149 us use a consistent location for the config.layout file, and it
150 makes configure more portable.
151 [jun-ichiro hagino <itojun@iijlab.net>]
153 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
154 csv/gnuplot format, rudimentary ssl support and various other tweaks
155 to make results more true to what is measured. The upshot of this it
156 turns out that 'ab' has often underreported the true performance of
157 apache. Often by a order of magnitude :-) See talk/paper of Sander
158 Temme <sctemme@covalent.net> at April ApacheCon 2001 for details.
159 [Dirk-Willem van Gulik]
161 *) Clean up mod_cgid's temporary request pool. Besides fixing a
162 storage leak this ensures that some unnecessary pipes are closed.
165 *) Performance: Add quick_handler hook. This hook is called at the
166 very beginning of the request processing before location_walk,
167 translate_name, etc. This hook is useful for URI keyed content
168 caches like Mike Abbott's Quick Shortcut Cache.
171 *) top_module global variable renamed to ap_top_module [Perl]
173 *) Move ap_set_last_modified to the core. This is a potentially
174 controversial change, because this is kind of HTTP specific. However
175 many protocols should be able to take advantage of this kind of
176 information. I expect that headers will need one more layer of
177 indirection for multi-protocol work, but this is a small step in
178 the right direction. [Ryan Bloom]
180 *) Enable mod_status by default. This matches what Apache 1.3 does.
183 *) Add a ScriptSock directive to the default config file. This is
184 only enabled when mod_cgid is used.
185 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
187 Changes with Apache 2.0.15
189 *) Untangled the buildconf script and eliminated the need for build's
190 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
191 libtool muck that is now under srclib/apr/build. [Roy Fielding]
193 *) Win32: Don't accept more connections than we have worker threads
197 *) Fix bug in the Unix threaded.c MPM that allowed child processes
198 to fork() new child processes.
201 *) Fix a major security problem with double-reverse lookup checking.
202 Previously, a client connecting over IPv4 would not be matched
203 properly when the server had an IPv6 listening socket. PR #7407
204 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
206 *) Change the way the beos MPM handles polling to allow it to stop and
207 restart. Problem was the sockets being polled were being reset by
208 the select call, so once it had accepted a connection it was no
209 longer listening on the UDP socket we use for shutdown instructions.
210 APR needs to be altered, patch on it's way. [David Reid]
212 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
213 on error exit from ap_getline(). Some other code got upset because
214 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
216 *) Handle ap_discard_request_body() being called more than once.
217 [Greg Ames, Jeff Trawick]
219 *) Get rid of an inadvertent close of file descriptor 2 in
220 mod_mime_magic. [Greg Ames, Jeff Trawick]
222 *) Add a hook, create_request. This hook allows modules to modify
223 a request while it is being created. This hook is called for all
224 request_rec's, main request, sub request, and internal redirect.
225 When this hook is called, the the r->main, r->prev, r->next
226 pointers have been set, so modules can determine what kind of
227 request this is. [Ryan Bloom]
229 *) Cleanup the build process a bit more. The Apache configure
230 script no longer creates its own helper scripts, it just
232 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
234 *) Stop the forced downgrade of the connection to HTTP/1.0 for
235 proxy requests. [Graham Leggett]
237 *) Avoid using sscanf to determine the HTTP protocol number in
238 the common case because sscanf is a performance hog. From
239 Mike Abbot's Accelerating Apache patch number 6.
240 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
242 *) Fix a security exposure in mod_access. Previously when IPv6
243 listening sockets were used, allow/deny-from-IPv4-address rules
244 were not evaluated properly (PR #7407). Also, add the ability to
245 specify IPv6 address strings with optional prefix length on Allow
246 and Deny. [Jeff Trawick]
248 *) Enhance rotatelogs so that a UTC offset can be specified, and
249 the logfile name can be formatted using strftime(3). (Brought
250 forward from 1.3.) [Ken Coar]
252 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
253 DuplicateHandle on an IOCompletionPort (a practice which
254 MS "discourages"). The new model does not rely on associating
255 the completion port with the listening sockets, thus the
256 completion port can be completely managed within the child
257 process. A dedicated thread accepts connections off the network,
258 then calls PostQueuedCompletionStatus() to wake up worker
259 threads blocked on the completion port.
262 *) Bring forward the --suexec-umask option which allows the
263 builder to preset the umask for suexec processes. [Ken Coar]
265 *) Add a -V flag to suexec, which causes it to display the
266 compile-time settings with which it was built. (Only
267 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
269 *) Mod_include should always unset the content-length if the file is
270 going to be passed through send_parsed_content. There is no to
271 determine if the content will change before actually scanning the
272 entire content. It is far safer to just remove the C-L as long
273 as we are scanning it. [Ryan Bloom]
275 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
276 request and not Proxy-Authenticate.
277 [Graham Leggett <minfrin@sharp.fm>]
279 Changes with Apache 2.0.14
281 *) Fix content-length computation. We ONLY compute a content-length if
282 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
283 or we already have all the data. [Ryan Bloom]
285 *) Report unbounded containers in the config file. Previously, a typo
286 in the </container> directive could result in the rest of the config
287 file being silently ignored, with undesired defaults used.
290 *) Make the old_write filter use the ap_f* functions for the buffering.
293 *) Move more code from the http module into the core server. This
294 is core code, basically the default handler, the default input
295 and output filters, and all of the core configuration directives.
296 All of this code is required in order for the server to work, with or
297 without HTTP. The server is closer to working without the HTTP
298 module, although there is still more to do. [Ryan Bloom]
300 *) Fix a number of SGI compile warnings throughout the server. Fix some
301 bad parameters to apr_bucket_read(). Fix a bad statement in
302 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
303 consistently; we were mixing apr_time_t and time_t in invalid ways
304 before. In load_file(), call apr_dso_error() instead of
305 apr_strerror() so that we get a more specific string on some platforms.
306 PR #6980 [Jeff Trawick]
308 *) Allow modules to query the MPM about it's execution profile. This
309 query API can and should be extended in the future, but for now,
310 max_daemons, and threading or forking is a very good start.
311 [Jon Travis <jtravis@covalent.net>]
313 *) Modify mod_include to send blocks of data no larger than 9k.
314 Without this, mod_include will wait until the whole file is parsed,
315 or the first tag is found to send any data to the client.
316 [Paul J. Reder <rederpj@raleigh.ibm.com>]
318 *) Fix mod_info, so that <Directory> and <Location> directives are
319 not displayed twice when displaying the current configuration.
320 [Ryan Morgan <rmorgan@covalent.net>]
322 *) Add config directives to override DEFAULT_ERROR_MSG and
323 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
324 [Dan Rench <drench@xnet.com>]
326 *) Get mod_info building and loading on Win32. [William Rowe]
328 *) Begin to move protocol independant functions out of mod_http. The goal
329 is to have only functions that are HTTP specific in the http directory.
332 Changes with Apache 2.0.13
334 *) Don't assume that there will always be multiple calls to the byterange
335 filter. It is possible that we will need to do byteranges with only
336 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
338 *) Move the error_bucket definition from the http module to the
339 core server. Every protocol will need this ability, not just
342 Changes with Apache 2.0.12
344 *) Modify mod_file_cache to save pre-formatted strings for
345 content-length and last-modified headers for performance.
346 [Mike Abbot <mja@trudge.engr.sgi.com>]
348 *) Namespace protect IOBUFSIZ since it is exposed in the API.
349 [Jon Travis <jtravis@covalent.net>]
351 *) Use "Basic" authentication instead of "basic" in ab, as the spec
352 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
354 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
355 without ever filling it out. This fixes PR 7271.
356 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
357 Cliff Woolley <cliffwoolley@yahoo.com>]
359 *) Add a couple of GCC attribute tags to printf style functions.
360 [Jon Travis <jtravis@covalent.net>]
362 *) Add the correct language tag for interoperation with the Taiwanese
363 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
365 *) Migrate the perchild MPM to use the new apr signal child, and
366 APR thread functions. [Ryan Bloom]
368 *) Close one copy of the CGI's stdout before creating the new process.
369 The CGI will still have stdout, because we have already dup'ed it.
370 This keeps Apache from waiting forever to send the results of a CGI
371 process that has forked a long-lived child process.
372 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
374 *) Remove the rest of the pthreads functions from the threaded MPM.
375 This requires the APR support for a signal thread that was just
378 *) Make mod_dir use a fixup for sending a redirect to the browser.
379 Before this, we were using a handler, which doesn't make much
380 sense, because the handler wasn't generating any data, it would
381 either return a redirect error code, or DECLINED. This fits the
382 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
384 *) Make the threaded MPM use APR threads instead of pthreads.
387 *) Get mod_tls to the point where it actually appears to work in all cases.
390 *) implement --enable-modules and --enable-mods-shared for "all" and
393 *) Move the threaded MPM to use APR locks instead of pthread locks.
396 *) Rename mpmt_pthread to threaded. This is more in line with the
397 fact that mpmt_pthread shouldn't be using pthreads directly, and
398 it is a smaller name that doesn't tie into anything.
401 *) Rename the module structures so that the exported symbol matches
402 the file name, and it is easier to automate the installation
403 process (generating LoadModule directives from the module filenames).
406 *) Remove the coalesce filter. With the ap_f* functions, this filter
407 is no longer needed. [Ryan Bloom]
409 Changes with Apache 2.0.11
411 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
412 added feature of allowing a uid/gid per child process. If no
413 uid/gid is specified, then Perchild behaves exactly like dexter.
416 *) Get perchild building again. [Ryan Bloom]
418 *) Don't disable threads just because we are using the prefork MPM.
419 If somebody wants to compile without threads, they must now add
420 --disable-threads to the configure command line. [Ryan Bloom]
422 *) Begin to move the calls to update_child_status into common code, so
423 that each individual MPM does not need to update the scoreboard itself.
426 *) Allow mod_tls to compile under Unix boxes where openssl has been
427 installed to the system include files.
428 [Gomez Henri <new-httpd@slib.fr>]
430 *) Cleanup the mod_tls configure process. This should remove any need
431 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
432 configure doesn't check that yet. [Ryan Bloom]
434 *) Add a very early prototype of SSL support (in mod_tls.c). It is
435 vital that you read modules/tls/README before attempting to build
438 *) Fix a potential seg fault on all platforms. David Reid fixed this
439 on BEOS, but the problem could happen anywhere, so we don't want
440 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
442 *) Add new LogFormat directive, %D, to log time it takes to serve a
443 request in microseconds. [Bill Stoddard]
445 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
446 SetOutputFilter. This corresponds nicely with the other Set
447 directives, which operate on containers while the Add* directives
448 tend to work directly on extensions. [Ryan Bloom]
450 *) Cleanup the header handling a bit. This uses the apr_brigade_*
451 functions for the buffering so that we don't need to compute
452 the length of the headers before we actually create the header
455 *) Allow filters to buffer data using the ap_f* functions. These have
456 become macros that resolve directly to apr_brigade_*.
459 *) Get the Unix MPM's to do a graceful restart again. If we are going
460 to register a cleanup with ap_cleanup_scoreboard, then we have to
461 kill the cleanup with the same function, and that function can't be
464 *) Install all required header files. Without these, it was not
465 possible to compile some modules outside of the server.
468 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
469 forward from 1.3 to 2.0, we missed a single line, which broke regex
470 aliases. [Ryan Bloom]
472 *) We have a poor abstraction in the protocol. This is a temporary
473 hack to fix the bug, but it will need to be fixed for real. If
474 we find an error while sending out a custom error response, we back
475 up to the first non-OK request and send the data. Then, when we send
476 the EOS from finalize_request_protocol, we go to the last request,
477 to ensure that we aren't sending an EOS to a request that has already
478 received one. Because the data is sent on a different request than
479 the EOS, the error text never gets sent down the filter stack. This
480 fixes the problem by finding the last request, and sending the data
481 with that request. [Ryan Bloom]
483 *) Make the server status page show the correct restart time, and
484 thus the proper uptime. [Ryan Bloom]
486 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
487 should reduce the amount of duplicate code that is required to
488 create CGI processes.
489 [Paul J. Reder <rederpj@raleigh.ibm.com>]
491 *) ap_new_connection() closes the socket and returns NULL if a socket
492 call fails. Usually this is due to a connection which has been
493 reset. [Jeff Trawick]
495 *) Move the Apache version information out of httpd.h and into release.h.
496 This is in preparation for the first tag with the new tag and release
499 *) Begin restructuring scoreboard code to enable adding back in
500 the ability to use IPC other than shared memory.
501 Get mod_status working on Windows again. [Bill Stoddard]
503 *) Make mod_status work with 2.0. This will work for prefork,
504 mpmt_pthread, and dexter. [Ryan Bloom]
506 *) Correct a typo in httpd.conf.
507 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
509 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
511 *) Get the correct IP address if ServerName isn't set and we can't
512 find a fully-qualified domain name at startup.
513 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
515 *) Make mod_cgid work with SuExec. [Ryan Bloom]
517 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
518 'extra' stat's for user/group since they should never occur, and now
519 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
520 volumes. [William Rowe]
522 *) Adopt apr features to simplify mod_includes. This changes the
523 behavior of the USER_NAME variable, unknown uid's are now reported
524 as USER_NAME="<unknown>" rather than the old user#000 result.
525 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
527 *) Adopt apr features for simplifing mod_userdir, and accept the new
528 Win32/OS2 exceptions without hiccuping. [William Rowe]
530 *) Replace configure --with-optim option by using and saving the
531 environment variable OPTIM instead. This is needed because configure
532 options do not support multiple flags separated by spaces.
535 *) Fix some byterange handling. If we get a byte range that looks like
536 "-999999" where that is past the end of the file, we should return
537 a PARTIAL CONTENT status code, and return the whole file as one big
538 byterange. This matches the 1.3 handling now. [Ryan Bloom]
540 *) Make the error bucket a real meta-data bucket. This means that the
541 bucket length is 0, and a read returns NULL data. If one of these
542 buckets is passed down after the headers are sent, this data will
543 just be ignored. [Greg Stein]
545 *) The prefork MPM wasn't killing child processes correctly if a restart
546 signal was received while the process was serving a request. The child
547 process would become the equivalent of a second parent process. If
548 we break out of the accept loop, then we need to do die after cleaning
549 up after ourselves. [Ryan Bloom]
551 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
552 restarts. [Ryan Bloom]
554 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
555 the most optimal APR_FINFO_wanted bits. This spares Win32 from
556 performing very expensive owner, group and permission lookups
557 and allows the server to function until these apr_finfo_t fields
558 are implemented under Win32. [William Rowe]
560 *) Support for typedsafe optional functions - that is functions exported by
561 optional modules, which, therefore, may or may not be present, depending
562 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
563 for sample code. [Ben Laurie]
565 *) filters can now report an HTTP error to the server. This is done
566 by sending a brigade where the first bucket is an error_bucket.
567 This bucket is a simple bucket that stores an HTTP error and
568 a string. Currently the string is not used, but it may be needed
569 to output an error log. The http_header_filter will find this
570 bucket, and output the error text, and then return
571 AP_FILTER_ERROR, which informs the server that the error web page
572 has already been sent. [Ryan Bloom]
574 *) If we get an error, then we should remove all filters except for
575 those critical to serving a web page. This fixes a bug, where
576 error pages were going through the byterange filter, even though
577 that made no sense. [Ryan Bloom]
579 *) Relax the syntax checking of Host: headers in order to support
580 iDNS. PR#6635 [Tony Finch]
582 *) Cleanup the byterange filter to use the apr_brigade_partition
583 and apr_bucket_copy functions. This removes a lot of very messy
584 code, and hopefully makes this filter more stable.
587 *) Remove AddModule and ClearModuleList directives. Both of these
588 directives were used to ensure that modules could be enabled
589 in the correct order. That requirement is now gone, because
590 we use hooks to ensure that modules are in the correct order.
593 *) When SuExec is specified, we need to add it to the list of
594 targets to be built. If we don't, then any changes to the
595 configuration won't affect SuExec, unless 'make suexec' is
596 specifically run. [Ryan Bloom]
598 *) Cleaned out open_file from mod_file_cache, as apr now accepts
599 the APR_XTHREAD argument to open a file for consumption by
600 parallel threads on win32. [William Rowe]
602 *) Correct a bug in determining when we follow symlinks. The code
603 expected a stat -1 result, not an apr_status_t positive error.
604 Also check if the APR_FINFO_USER fields are valid before we
605 follow the link. [William Rowe]
607 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
608 mpm_common.c. These functions are only valid on some platforms,
609 so they should not be in the main-line code. [Ryan Bloom]
611 *) Remove ap_chdir_file(). This function is not thread-safe,
612 and nobody is currently using it. [Ryan Bloom]
614 *) Do not try to run make depend if there are no .c files in the
615 current directory, doing so makes `make depend` fail.
618 *) Update highperformance.conf to work with either prefork or
619 pthreads mpms. [Greg Ames]
621 *) Stop checking to see if this is a pipelined request if we know
622 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
623 This keeps us from making an extra read call when serving a 1.0
624 request. [Ryan Bloom and Greg Stein]
626 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
627 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
628 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
630 *) Fix the RFC number mentioned when complaining about a missing
631 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
633 *) Fix an endless loop in ab which occurred when ab was posting
634 and the server dropped the connection unexpectedly.
637 *) Fix a segfault while handling request bodies in ap_http_filter().
638 This problem has been seen with mod_dav usage as well as with
639 requests where the body was just being discarded. [Jeff Trawick]
641 *) Some adjustment on the handling and automatic setting (via
642 hints.m4) of various compilation flags (eg: CFLAGS). Also,
643 add the capability to specify flags (NOTEST_CFLAGS and
644 NOTEST_LDFLAGS) which are used to compile Apache, but
645 not used during the configuration process. Useful for
646 flags like "-Werror". [Jim Jagielski]
648 *) Stop using environment variables to force debug mode or
649 no detach. We now use the -D command line argument to
650 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
651 [Greg Stein, Ryan Bloom]
653 *) Change handlers to use hooks. [Ben Laurie]
655 *) Stop returning copies of filenames from both apr_file_t and
656 apr_dir_t. We pstrdup the filenames that we store in the
657 actual structures, so we don't need to pstrdup the strings again.
660 *) mod_cgi: Fix some problems where the wrong error value was being
661 traced. [Jeff Trawick]
663 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
666 *) Add generic hooks. [Ben Laurie]
668 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
670 *) Fix a segfault caused by mod_ext_filter when the external filter
671 program does not exist. [Jeff Trawick]
673 *) Fix an output truncation error when on an HTTP >= 1.0 request an
674 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
675 was served through mod_charset_lite (or anything else that would
676 create a transient bucket in this size range). ap_bucket_make_heap()
677 silently failed (fixed), transient_setaside() discovered it, but
678 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
680 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
681 is that some browsers send extra lines at the end of POST requests, and
682 we don't want to delay sending data back to the user just because the
683 browser isn't well behaved. [Ryan Bloom]
685 *) Get SuEXEC working again. We can't send absolute paths to suExec
686 because it refuses to execute those programs. SuEXEC also wasn't
687 always recognizing configuration changes made using the autoconf
690 *) Allow the buildconf process to find the config.m4 files in the correct
691 order. Basically, we can now name config.m4 files as config\d\d.m4,
692 and we will sort them correctly when inserting them into the build
693 process. [Ryan Bloom]
695 *) Get mod_cgid to use apr calls for creating the actual CGI process.
696 This also allows mod_cgid to use ap_os_create_priviledged_process,
697 thus allowing for SuExec execution from mod_cgid. Currently, we do
698 not support everything that standard SuExec supports, but at least
699 it works minimally now. [Ryan Bloom]
701 *) Allow SuExec to be configured from the ./configure command line.
704 *) Update some of the docs in README and INSTALL to reflect some of
705 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
707 *) If we get EAGAIN returned from the call to apr_sendfile, then we
708 need to call sendfile again. This gets us serving large files
709 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
711 *) Get the support programs building cleanly again.
712 [Cliff Woolley <cliffwoolley@yahoo.com>]
714 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
715 current directory logic now backs up over bin/ to determine the
716 server root from the Apache.exe path.
718 *) Apache/Win32 now follows the standard conventions of mod_foo.so
719 loadable modules, dynamic libs are all named libfoo.dll, and the
720 makefile.win populates the include, lib and libexec directories.
722 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
723 Apache gets IPv6 listening sockets by default. Additionally, the
724 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
725 numeric address strings (e.g., "Listen [fe80::1]:8080").
728 *) Modify the install directory layout. Modules are now installed in
729 modules/. Shared libraries should be installed in libraries/, but
730 we don't have any of those on Unix yet. All install directories
731 are modifyable at configure time. [Ryan Bloom]
733 *) Install all header files in the same directory on Unix. [Ryan Bloom]
735 *) Get the functions in server/linked into the server, regardless of
736 which modules linked into the server. This uses the same hack
737 for Apache that we use for APR and apr-util to ensure all of the
738 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
739 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
740 the scripts a bit easier.
743 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
744 on the query, and remove IPv4 dependencies. [Jeff Trawick]
746 *) Get all of the auth modules to the point that they will install and
747 be loadable into the server. Our new build/install mechanism expects
748 that all modules will have a common name format. The auth modules
749 didn't use that format, so we didn't install them properly.
752 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
753 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
755 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
757 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
758 after the end of the response. [Ryan Bloom]
760 *) Get byterange requests working with responses that do not have a
761 content-length. Because of the way byterange requests work, we have to
762 have all of the data before we can actually do the byterange, so we
763 can compute the content-length in the byterange filter.
766 *) Get exe CGI's working again on Windows.
769 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
770 they keep track of whether or not their post config hook has been
771 called before. Instead of a static variable (which is replaced when
772 the DSO is loaded a second time), use userdata in the process pool.
775 Changes with Apache 2.0a9
777 *) Win32 now requires perl to complete the final install step for users
778 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
779 and installs the conf, htdocs and htdocs/manual directories.
782 *) Make mod_include use a hash table to associate directive tags with
783 functions. This allows modules to implement their own SSI tags easily.
784 The idea is simple enough, a module can insert it's own tag and function
785 combination into a hash table provided by mod_include. While mod_include
786 parses an SSI file, when it encounters a tag in the file, it does a
787 hash lookup to find the function that implements that tag, and passes
788 all of the relevant data to the function. That function is then
789 responsible for processing the tag and handing the remaining data back
790 to mod_include for further processing.
791 [Paul J. Reder <rederpj@raleigh.ibm.com>]
793 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
794 fewer parameters: the local and remote socket addresses were removed
795 from the parameter list because all required information is available
796 via the APR socket. [Jeff Trawick]
798 *) Distribution directory structure reorganized to reflect a
799 normal source distribution with external install targets.
802 *) The MPMs that need multiple segments of shared memory now create
803 two apr_shmem_t variables, one for each shared memory allocation.
804 the problem is that we can't determine how much memory will be required
805 for shared memory allocations once we try to allocate more than one
806 variable. The MM code automatically aligns the shared memory allocations,
807 so we end up needing to pad the amount of shared memory we want based
808 on how many variables will be allocated out of the shared memory segment.
809 It is just easier to create a second apr_shmem_t variable, and two
813 *) Cleanup the export list a bit. This creates a single unified list of
814 functions exported by APR. The export list is generated at configure
815 time, and that list is then used to generate the exports.c file.
816 Because of the way the export list is generated, we only export those
817 functions that are valid on the platform we are building on.
820 *) Enable logging the cookie with mod_log_config
821 [Sander van Zoest <sander@covalent.net>]
823 *) Fix a segfault in mod_info when it reaches the end of the configuration.
826 *) Added lib/aputil/ as a placeholder for utility functions which are not
827 specific to the Apache HTTP Server (but do not make sense with APR).
828 The first utility is "apu_dbm": a set of functions to work with DBM
829 files. This first version can be compiled for SDBM or GDBM databases.
832 *) Complete re-write of mod_include. This makes mod_include a filter that
833 uses buckets directly. This has now served the FAQ correctly.
834 [Paul Reder <rederpj@raleigh.ibm.com>]
836 *) Allow modules to specify the first filter in a sub_request when
837 making the sub_request. This keeps modules from having to change the
838 output_filter immediately after creating the sub-request, and therefore
839 skip the sub_req_output_filter. [Ryan Bloom]
841 *) Update ab to accept URLs with IPv6 literal address strings (in the
842 format described in RFC 2732), and to build Host header fields in
843 the same format. This allows IPv6 literal address strings to be
844 used with ab. This support has been tested against Apache 1.3 with
845 the KAME patch, but Apache 2.0 does not yet work with this format
846 of the Host header field. [Jeff Trawick]
848 *) Accomodate an out-of-space condition in the piped logs and the
849 rotatelogs.c code, and no longer churn log processes for this
850 condition. [Victor J. Orlikowski]
852 *) Add support for partial writes with apr_sendfile() to core_output_filter.
855 Changes with Apache 2.0a8
857 *) Add a directive to mod_mime so that filters can be associated with
861 *) Get multi-views working again. We were setting the path_info
862 field incorrectly if we couldn't find the specified file.
865 *) Fix 304 processing. The core should never try to send the headers
866 down the filter stack. Always, just setup the table in the request
867 record, and let the header filter convert it to data that is ready
871 *) More fixes for the proxy. There are still bugs in the proxy code,
872 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
876 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
879 *) APR: Add new apr_getopt_long function to handle long options.
880 [B. W. Fitzpatrick <fitz@red-bean.com>]
882 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
883 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
884 hostname resolution/address string parsing and building
885 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
886 of one of the apr_sockaddr_t structures for a socket. Change
887 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
889 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
890 I have proxied pages with it, cleanup will commence soon.
893 *) Make the proxy work with filters. This isn't perfect, because we
894 aren't dealing with the headers properly. [Ryan Bloom]
896 *) Do not send a content-length iff the C-L is 0 and this is a head
897 request. [Ryan Bloom]
899 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
900 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
902 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
904 *) Get the default_handler to stop trying to deal with HEAD requests.
905 The idea is to let the content-length filter compute the C-L before
906 we try to send the data. If we can get the C-L correctly, then we
907 should send it in the HEAD response.
910 *) The Header filter can now determine if a body should be sent based
911 on r->header_only. The general idea of this is that if we delay
912 deciding to send the body, then we might be able to compute the
913 content-length correctly, which will help caching proxies to cache
914 our data better. Any handler that doesn't want to try to compute
915 the content-length can just send an EOS bucket without data and
916 everything will just work.
919 *) Add the referer to the error log if one is available.
920 [Markus Gyger <mgyger@itr.ch>]
922 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
923 change, the root of the configuration tree has been exposed to modules
925 [Ryan Morgan <rmorgan@covalent.net>]
927 *) Get the core_output_filter to use the bucket interface directly.
928 This keeps us from calling the content-length filter multiple times
929 for a simple static request.
932 *) We are sending the content-type correctly now.
933 [Ryan Bloom and Will Rowe]
935 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
936 a bogus bytes-sent value when the only thing being sent was trailers
937 and writev() returned an error (or EAGAIN). [Jeff Trawick]
939 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
940 hints file to determine which platforms define
941 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
944 *) APR: add apr_get_home_directory() [Jeff Trawick]
946 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
948 *) Not all platforms have INADDR_NONE defined by default. Apache
949 used to make this check and define INADDR_NONE if appropriate,
950 but APR needs the check too, and I suspect other applications will
951 as well. APR now defines APR_INADDR_NONE, which is always a valid
952 value on all platforms.
953 [Branko Èibej <brane@xbc.nu>]
955 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
956 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
958 *) Relax the syntax checking of Host: headers in order to support
959 iDNS. PR#6635 [Tony Finch]
961 *) When reading from file buckets we convert to an MMAP if it makes
962 sense. This also simplifies the default handler because the
963 default handler no longer needs to try to create MMAPs.
966 *) BUFF has been removed from the main server. The BUFF code will remain
967 in the code until it has been purged from the proxy module as well.
970 *) Byteranges have been completely re-written to be a filter. This
971 has been tested, and I believe it is working correctly, but it could
972 doesn't work for the Adobe Acrobat plug-in. The output almost matches
973 the output from 1.3, the only difference being that 1.3 includes
974 a content-length in the response, and this does not.
977 *) APR read/write functions and bucket read functions now operate
978 on unsigned integers, instead of signed ones. It doesn't make
979 any sense to use signed ints, because we return the error codes,
980 so if we have an error we should report 0 bytes read or written.
983 *) Always compute the content length, whether it is sent or not.
984 The reason for this, is that it allows us to correctly report
985 the bytes_sent when logging the request. This also simplifies
986 content-length filter a bit, and fixes the actual byte-reporing
987 code in mod_log_config.c
990 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
991 it says, because it was only used by EOS and FLUSH buckets. Since
992 neither of those are required at the end of a brigade, this was
993 really signifying FLUSH_THE_DATA, but that can be determined better
994 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
995 buckets now return a length of 0, which is actually the amount of data
996 read, so they make more sense.
999 *) Allow the core_output_filter to save some data past the end of a
1000 request. If we get an EOS bucket, we only send the data if it
1001 makes sense to send it. This allows us to pipeline request
1002 responses. As a part of this, we also need to allocate mmap
1003 buckets out of the connection pool, not the request pool. This
1004 allows the mmap to outlive the request.
1007 *) Make blocking and non-blocking bucket reads work correctly for
1008 sockets and pipes. These are the only bucket types that should
1009 have non-blocking reads, because the other bucket types should
1010 ALWAYS be able to return something immediately.
1013 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
1014 server, but use Ctrl+Break to initiate a graceful restart
1015 instead of duplicating behavior. [John Sterling]
1017 *) Patch mod_autoindex to set the Last-Modified header based on
1018 the directory's mtime, and add the ETag header. [William Rowe]
1020 *) Merge the 1.3 patch to add support for logging query string in
1021 such a way that "%m %U%q %H" is the same as "%r".
1024 *) Port three log methods from mod_log_config 1.3 to 2.0:
1025 CLF compliant '-' byte count, method and protocol.
1028 *) Add a new LogFormat directive, %c, that will log connection
1029 status at the end of the response as follows:
1030 'X' - connection aborted before the response completed.
1031 '+' - connection may be kept-alive by the server.
1032 '-' - connection will be closed by the server.
1035 *) Expand APR for WinNT to fully accept and return utf-8 encoded
1036 Unicode file names and paths for Win32, and tag the Content-Type
1037 from mod_autoindex to reflect that charset if the the feature
1038 macro APR_HAS_UNICODE_FS is true. [William Rowe]
1040 *) Compute the content length (and add appropriate header field) for
1041 the response when no content length is available and we can't use
1042 chunked encoding. [Jeff Trawick]
1044 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
1045 so that content input filters get dechunked data when using
1046 the default handler. Also removed REQUEST_CHUNKED_PASS.
1049 *) Add mod_ext_filter as an experimental module. This module allows
1050 the administrator to use external programs as filters. Currently,
1051 only filtering of output is supported. [Jeff Trawick]
1053 *) Most Apache functions work on EBCDIC machines again, as protocol
1054 data is now translated (again). [Jeff Trawick]
1056 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
1057 the EBCDIC support. They are noops on ASCII machines, so this
1058 type of translation doesn't have to be surrounded by #ifdef
1059 CHARSET_EBCDIC. [Jeff Trawick]
1061 *) Fix mod_include. tag commands work again, and the server will
1062 send the FAQ again. This also allows mod_include to set aside
1063 buckets that include partial buckets.
1064 [Ryan Bloom and David Reid]
1066 *) Add suexec support back. [Manoj Kasichainula]
1068 *) Lingering close now uses the socket directly instead of using
1069 BUFF. This has been tested, but since all we can tell is that it
1070 doesn't fail, this needs to be really hacked on.
1073 *) Allow filters to modify headers and have those headers be sent to
1074 the client. The idea is that we have an http_header filter that
1075 actually sends the headers to the network. This removes the need
1076 for the BUFF to send headers.
1079 *) Charset translation: mod_charset_lite handles translation of
1080 request bodies. Get rid of the xlate version of ap_md5_digest()
1081 since we don't compute digests of filtered (e.g., translated)
1082 response bodies this way anymore. (Note that we don't do it at
1083 all at the present; somebody needs to write a filter to do so.)
1086 *) Input filters and ap_get_brigade() now have a input mode parameter
1087 (blocking, non-blocking, peek) instead of a length parameter.
1090 *) Update the mime.types file to the registered media types as
1091 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
1094 *) Namespace protect some macros declared in ap_config.h
1097 *) Support HTTP header line folding with input filtering.
1100 *) Mod_include works again. This should still be re-written, but at
1101 least now we can serve an SHTML page again.
1104 *) Begin to remove BUFF from the core. Currently, we keep a pointer
1105 to both the BUFF and the socket in the conn_rec. Functions that
1106 want to use the BUFF can, functions that want to use the socket,
1107 can. They point to the same place.
1110 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
1111 [Tomas "Ögren" <stric@ing.umu.se>]
1113 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
1114 associated pool goes away. (APR pipes on OS/2 were already had this
1115 logic.) This resolvs a fatal file descriptor leak with CGIs.
1118 *) The final line of the config file was not being read if there was
1119 no \n at the end of it. This was caused by apr_fgets returning
1120 APR_EOF even though we had read valid data. This is solved by
1121 making cfg_getline check the buff that was returned from apr_fgets.
1122 If apr_fgets return APR_EOF, but there was data in the buf, then we
1123 return the buf, otherwise we return NULL.
1126 *) Piped logs work again in the 2.0 series.
1129 *) Restore functionality broken by the mod_rewrite security fix:
1130 rewrite map lookup keys and default values are now expanded
1131 so that the lookup can depend on the requested URI etc.
1132 PR #6671 [Tony Finch]
1134 *) Tighten up the syntax checking of Host: headers to fix a
1135 security bug in some mass virtual hosting configurations
1136 that can allow a remote attacker to retrieve some files
1137 on the system that should be inaccessible. [Tony Finch]
1139 *) Add a pool bucket type. This bucket is used for data allocated out
1140 of a pool. If the pool is cleaned before the bucket is destroyed, then
1141 the data is converted to a heap bucket, allowing it to survive the
1145 *) Add a flush bucket. This allows modules to signal that the filters
1146 should all flush whatever data they currently have. There is no way
1147 to actually force them to do this, so if a filter ignores this bucket,
1148 that's life, but at least we can try with this.
1151 *) Add an output filter for sub-requests. This filter just strips the
1152 EOS bucket so that we don't confuse the main request's core output
1153 filter by sending multiple EOS buckets. This change also makes sub
1154 requests start to send EOS buckets when they are finished.
1157 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
1158 makes ap_bucket_destroy a return void, which is okay because it
1159 used to always return APR_SUCCESS, and nobody ever checked its
1160 return value anyway.
1161 [Cliff Woolley <cliffwoolley@yahoo.com>]
1163 *) Remove the index into the bucket-type table from the buckets
1164 structure. This has now been replaced with a pointer to the
1165 bucket_type. Also add some macros to test the bucket-type.
1168 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
1169 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
1170 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
1171 All _VAR_ flavors changes to _DATA to be absolutely clear.
1174 *) Add support for /, //, //servername and //server/sharename
1175 parsing of <Directory> blocks under Win32 and OS2.
1176 [Tim Costello, William Rowe, Brian Harvard]
1178 *) Remove the function pointers from the ap_bucket type. They have been
1179 replaced with a global table. Modules are allowed to register bucket
1180 types and use then use those buckets.
1183 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
1184 once we finish writing the request body to the cgi child process;
1185 otherwise, the client doesn't hit EOF on stdin. Small request bodies
1186 worked without this change (for reasons I don't understand), but large
1187 ones didn't. [Jeff Trawick]
1189 *) Remove file bucket specific information from the ap_bucket type.
1190 This has been moved to a file_bucket specific type that hangs off
1191 the data pointer in the ap_bucket type.
1194 *) Input filtering now has a third argument. This is the amount of data
1195 to read from lower filters. This argument can be -1, 0, or a positive
1196 number. -1 means give me all the data you have, I'll deal with it and
1197 let you know if I need more. 0 means give me one line and one line
1198 only. A positive number means I want no more than this much data.
1200 Currently, only 0 and a positive number are implemented. This allows
1201 us to remove the remaining field from the conn_rec structure, which
1205 *) Big cleanup of the input filtering. The goal is that http_filter
1206 understands two conditions, headers and body. It knows where it is
1207 based on c->remaining. If c->remaining is 0, then we are in headers,
1208 and http_filter returns a line at a time. If it is not 0, then we are
1209 in body, and http_filter returns raw data, but only up to c->remaining
1210 bytes. It can return less, but never more.
1211 [Greg Ames, Ryan Bloom, Jeff Trawick]
1213 *) mod_cgi: Write all of the request body to the child, not just what
1214 the kernel would accept on the first write. [Jeff Trawick]
1216 *) Back out the change that moved the brigade from the core_output_filters
1217 ctx to the conn_rec. Since all requests over a given connection
1218 go through the same core_output_filter, the ctx pointer has the
1222 *) Fix another bug in the send_the_file() read/write loop. A partial
1223 send by apr_send would cause unsent data in the read buffer to
1224 get clobbered. Complete making send_the_file handle partial
1225 writes to the network.
1228 *) Fix a couple of type fixes to allow compilation on AIX again
1229 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
1231 *) Fix bug in send_the_file() which causes offset to be ignored
1232 if there are no headers to send.
1235 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
1236 filter. Useful for supporting Windows 9* with a binary
1237 compiled on Windows NT.
1240 Changes with Apache 2.0a7
1242 *) Reimplement core_output_filter to buffer/save bucket brigades
1243 across multiple calls to the core_filter. The brigade will be
1244 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
1245 thresholds are hit or the EOS bucket is received.
1248 *) Create experimental filter (buffer_filter) that coalesces bytes
1249 into one large buffer before invoking the next filter in the
1250 chain. This filter is particularly useful with the current
1251 implementation of mod_autoindex when it inserted above the
1252 chunk_filter. mod_autoindex generates a lot of brigades that
1253 containing buckets holding just a few bytes each. The
1254 buffer_filter coalesces these buckets into a single large bucket.
1257 *) Add apr_sendfile() support into the core_output_filter.
1260 *) Add apr_sendv() support into the core_output_filter.
1263 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
1264 [Mike Abbott <mja@sgi.com>]
1266 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
1267 make much sense, because Apache uses buckets instead of BUFFs now.
1270 *) send_the_file now falls back to a read/write loop on platforms that
1271 do not have sendfile.
1272 [Ryan Bloom and Brian Havard]
1274 *) Install apachectl correctly, and substitute the proper values so
1275 that it works again. [Ryan Bloom]
1277 *) Better(??) handle platforms that lack sendfile().
1280 *) APR now has UUID generation/formatting/parsing support.
1283 *) Begin the http_filter. This is an input filter that understands
1284 the absolute basic amount required to parse an HTTP Request. The
1285 goal is to be able to split headers from request body before passing
1286 the data back to the other filters.
1289 *) Bring forward from 1.3.13 the config directory implementation
1292 *) install apxs if it is created
1295 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
1296 conversions. [William Rowe]
1298 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
1299 ap_add_output_filter(). [Jeff Trawick]
1301 *) Multiple build and configuration fixes
1304 -add datadir and localstatedir substitutions
1306 -fix logfilename misspelling
1307 -fix evaluation of installation dir variables and
1308 -replace $foobar by $(foobar) to be usefull in the makefile
1312 -add rules for cross-compiling in rules.mk. Okay, rule to check for
1313 $CC_FOR_BUILD is still missing
1314 -use CHECK_TOOL instead of CHECK_PROG for ranlib
1315 -add missing "AR=@AR@" to severaly Makefile.in's
1316 -cache result for "struct rlimit"
1317 -compile all helper programs with native and cross compiler
1318 and use the native version to generate header file
1319 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
1321 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
1323 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
1325 *) Fix a bug where a client which only sends \n to delimit header
1326 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
1327 message. Start working on ebcdic co-existance with input
1329 [William Rowe, Greg Ames]
1331 *) If mod_so is enabled in the server always create libexec, even
1332 if there are no modules installed in this directory. This is a
1333 requirement for APXS to work correctly.
1336 *) Connection oriented output filters are now stored in the
1337 conn_rec instead of the request_rec. This allows us to add the
1338 output filter in the pre-connection phase instead of the
1339 post_read_request phase, which keeps us from trying to write an
1340 error page before we have a filter to write to the network.
1341 [Ryan Bloom, Jeff Trawick, and Greg Ames]
1343 *) Cleaning up an mmap bucket no longer deletes the mmap. An
1344 mmap can be used across multiple buckets (default_handler with
1345 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
1346 the mmap itself can't be associated with the bucket.
1349 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
1352 *) Radical surgery to improve mod_isapi support under Win32.
1353 Includes a number of newer ServerSupportFunction calls, support
1354 for ReadClient (in order to retrieve POSTs greater than 48KB),
1355 and general bug fixes to more reliably load ISAPI .dll's and
1356 prevent leaking handle resources. Note: There are still
1357 discrepancies between IIS's and Apache's ServerVariables, and
1358 async calls are still not supported. Additional warnings are
1359 logged to facilitate debugging of unsupported ISAPI calls.
1362 *) Add input filtering to Apache. The basic idea for the input
1363 filters is the same as the ideas for output filters. The biggest
1364 difference is that instead of calling ap_pass_brigade, ap_get_brigade
1365 should be called, and the order of execution for the filter itself is
1366 different. When writing an output filter, a brigade is passed in,
1367 and filters operate directly on that brigade, when done, they call
1368 ap_pass_brigade. Input filters are the exact opposite. Because input
1369 is not a push operation, filters first call ap_get_brigade. When this
1370 function returns, the input filter will be left with a valid brigade.
1371 The input filter should then operate on the brigade, and return.
1374 *) Fix building on BSD/OS using its native make. The build system
1375 falls back to the BSD .include directive on that host platform.
1378 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
1379 SHA1 and plaintext password encodings. Make feature tests a
1380 bit more flexible. [William Rowe]
1382 *) Charset translation: mod_charset_lite handles output content
1383 translation in a filter. mod_charset_lite no longer ignores
1384 subrequests. A bunch of cruft related to BUFF's support for
1385 translating request and response bodies was removed.
1388 *) Move the addition of the CORE filter to the post_read_request
1389 hook in http_core.c. This removes the need to add the filter in
1390 multiple places and allows for an SSL module to be added much
1391 simpler. [Ryan Bloom]
1393 *) Fix a security problem that affects certain configurations of
1394 mod_rewrite. If the result of a RewriteRule is a filename that
1395 contains expansion specifiers, especially regexp backreferences
1396 $0..$9 and %0..%9, then it may be possible for an attacker to
1397 access any file on the web server. [Tony Finch]
1399 *) Fix a bug where errors that are detected during early request parsing
1400 don't produce visible HTTP error messages at the browser, because
1401 the core_filter wasn't present. [Greg Ames]
1403 *) Provide apr_socklen_t as a portability aid.
1404 [Victor J. Orlikowski]
1406 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
1407 as well as a comment arg to the add, adduser and update cmds.
1408 update allows the user to clear or preserve pw/groups/comment.
1409 Fixed a bug in dbmmanage that prevented the check option from
1410 parsing a password followed by :group... text. Corrected the
1411 seed calcualation for Win32 systems, and added -lsdbm support.
1414 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
1417 *) Avoid a segfault when parsing .htaccess files. An
1418 uninitialized tree pointer was passed to ap_build_config().
1421 *) Change the way that inet_addr & inet_network are checked for
1422 in APR's configure process to allow BeOS BONE to correctly
1423 find them. With this change BeOS BONE now builds from source
1424 with no problems. [David Reid]
1426 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
1427 the end of the parameters to execve() was stored in the wrong
1428 location, overlaying the storage beyond the newargs[] array and
1429 also passing uninitialized storage to execve(), which would
1430 sometimes fail with EFAULT. [Jeff Trawick]
1432 *) Fix a bug parsing configuration file containers. With a sequence
1433 like this in the config file
1435 <IfModule mod_kilroy.c>
1438 <IfModule mod_lovejoy.c>
1443 the second container would be terminated at the blank line due to
1444 sediment in the buffer from reading the prior </IfModule> and an
1445 error message would be generated for the real </IfModule> for the
1446 second container. Also due to this problem, any two characters
1447 could be used for "</" in the close of a container.
1450 *) ap_add_filter prototype changed to remove the ctx pointer. The
1451 pointer still remains in the filter structure, but it can not be
1452 a part of the ap_add_filter prototype. The reason is that when
1453 the core uses AddFilter to add a filter to the stack it doesn't
1454 know how to allocate the ctx pointer, or even how much memory should
1455 be allocated. The filters will have to be responsible for allocating
1456 the ctx memory when they need it.
1459 *) Add an AddFilter directive. This directive takes a list of filters
1460 that should be activated for the requested resource.
1463 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
1464 some other platforms). [Jeff Trawick]
1466 *) Modify mod_include to be a filter. Currently, it has only been tested
1467 on actual files, but it should work for CGI scripts too.
1470 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
1471 writes. apr_flush() for Unix: handle interrupted writes.
1474 *) NameVirtualHost can now take "*" as an argument instead of
1475 an IP address. This allows you to create a purely name-based
1476 virtual hosting server that does not have any IP addresses in
1477 the configuration file and which ignores the local address
1478 of any connections. PR #5595, PR #4455 [Tony Finch]
1480 *) Fix some compile warnings in mod_mmap_static.c
1481 [Mike Abbott <mja@sgi.com>]
1483 *) Fix chunking problem with CGI scripts. The general problem was that
1484 the CGI modules were adding an EOS bucket and then the core added an
1485 EOS bucket. The chunking filter finalizes the chunked response when it
1486 encounters an EOS bucket. Because two EOS buckets were sent, we
1487 finalized the response twice. The fix is to make sure we only send one
1488 EOS, by utilizing a flag in the request_rec.
1491 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
1492 and Win32. Previously, the first read from an apr_file_t set up via
1493 apr_put_os_file() would return a '\0'. [Jeff Trawick]
1495 *) Mod_cgid now creates a single element bucket brigade, with a pipe
1496 bucket, instead of using BUFF's and ap_r*.
1499 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
1500 [Mike Abbott <mja@sgi.com>]
1502 *) Remove ap_bopenf from buff code. This required modifying the file_cache
1503 code to use APR file's directly instead of going through BUFFs.
1506 *) Fix compile break on some platforms for mod_mime_magic.c
1507 [John K. Sterling <sterling@covalent.net>]
1509 *) Fix merging of AddDefaultCharset directive.
1510 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
1512 *) Minor revamp of the rlimit sections of code. We now test
1513 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
1514 is now "available" even if the platform doesn't support
1515 the rlimit family (it's just a noop though). [Jim Jagielski]
1517 *) Migrate the pre-selection of which MPM to use for specific
1518 platforms to hints.m4, which contains (or should contain)
1519 all platform specific "hints". [Jim Jagielski]
1521 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
1524 *) Add tables with non-string/binary values to APR.
1527 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
1530 *) Update PCRE to version 3.2. [Ryan Bloom]
1532 *) Change the way buckets' destroy functions are called so that
1533 they can be more directly used when changing the type of a
1534 bucket in place. [Tony Finch]
1536 *) Add generic support for reference-counting the resources used by
1537 buckets, and alter the HEAP and MMAP buckets to use it. Change
1538 the way buckets are initialised to support changing the type of
1539 buckets in place, and use it when setting aside TRANSIENT buckets.
1540 Change the implementation of TRANSIENT buckets so that it can be
1541 mostly shared with IMMORTAL buckets, which are now implemented.
1544 Changes with Apache 2.0a6
1546 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
1548 *) Add a chunking filter to Apache. This brings us one step closer
1549 to removing BUFF. [Ryan Bloom]
1551 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
1552 added to the stack is the last filter to be called. [Ryan Bloom]
1554 *) Apache 2.0 has been completely documented using Scandoc. The
1555 docs can be generated by running 'make docs'. [Ryan Bloom]
1557 *) Add filtered I/O to Apache. This is based on bucket brigades,
1558 Currently the buckets still use BUFF under the covers, but that
1559 should change quickly. The only currently written filter is the
1560 core filter which just calls ap_bwrite. [The Apache Group]
1562 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
1563 built with thread support. [Jeff Trawick]
1565 *) Abort configuration if --with-layout was specified and there's
1566 no layout definition file. [Ken Coar]
1568 *) Add support for '--with-port=n' option to configure. [Ken Coar]
1570 *) Add support for extension methods for the Allow response header
1571 field, and an API routine for accessing r->allowed and the
1572 list of extension methods in a unified manner. [Ken Coar]
1574 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
1575 [Rob Simonson <simo@us.ibm.com>]
1577 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
1578 APACHE_XLATE builds. [Jeff Trawick]
1580 *) A configuration file parsing problem was fixed. When the
1581 configuration file started with an IfModule/IfDefine container,
1582 only the last statement in the container would be retained.
1585 Changes with Apache 2.0a5
1587 *) Perchild is serving pages after passing them to different child
1588 processes. There are still a lot of bugs, but this does work. I
1589 have made requests against the same installation of Apache, and had
1590 different servers use different user IDs to serve the responses.
1591 This change moves to using socketpair instead of an AF_UNIX socket.
1594 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
1595 It can't seem to pass between child processes yet, but I think we
1596 are closer now than before. This moves us back to using Unix
1597 Domain Sockets. [Ryan Bloom]
1599 *) libapr functions and types renamed with apr_ prefix.
1600 #include "apr_compat.h" for 1.3.x backwards compat
1603 *) Fix problems with APR sockaddr handling on Win32. It didn't always
1604 return the right information on the local socket address.
1605 [Gregory Nicholls <gnicholls@level8.com>]
1607 *) ap_recv() on Win32: Set bytes-read to 0 on error.
1608 [Gregory Nicholls <gnicholls@level8.com>]
1610 *) Add an option to not detach from the controlling terminal without
1611 going into single process mode. This allows for much easier
1612 debugging of the process startup code. [Ryan Bloom]
1614 *) ab: don't use perror() to report the failure of an APR function.
1617 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
1618 scoreboard on graceful restarts.
1621 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
1622 An invalid ap_proc_t was passed to ap_create_process().
1625 *) Allow modules to register filters. Those filters are still
1626 never called, but this is a step in the right direction.
1627 [Ryan Bloom and Greg Stein]
1629 *) Register the mod_cgid daemon process for cleanup so that it is
1630 killed at termination if it does not die when the parent gets
1631 SIGTERM. This change is to fix occasional problems where the
1632 process stays around. Bugs in similar logic in mod_rewrite and
1633 mod_include were also fixed. [Jeff Trawick]
1635 *) Fix a bug in the time handling. Basically, we were imploding a time
1636 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
1637 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
1638 uses those two fields to adjust the time value. Because of the HTTP
1639 spec, both of those values can be zero'ed out safely. This fixes
1640 the bug correctly. [Ryan Bloom]
1642 *) Fix a couple of place in the Windows code where the wrong error
1643 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
1645 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
1647 *) Added the APR_EOL_STR macro for platform dependent differences in
1648 logfiles and other raw text (such as all APR files). Fixes logfiles
1649 not terminated with cr/lf sequences in Win32. [William Rowe]
1651 *) Move all strings functions in APR to src/lib/apr/strings and create
1652 apr_strings.h for the prototypes. [Ryan Bloom]
1654 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
1655 to repeat the syscall until we stop getting EINTR. I noticed a
1656 related problem at termination (SIGTERM) on FreeBSD when using
1657 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
1658 implementation work properly with child init. Previously, ap_lock()
1659 was essentially a no-op because all children were using different
1660 locks and thus nobody ever blocked. [Jeff Trawick]
1662 *) The htdocs/ tree has been moved out of the CVS source tree into
1663 a separate area for easier development. This has NO EFFECT on
1664 end-users or Apache installations. [Ken Coar]
1666 *) Integrate the mod_dav module for WebDAV protocol handling. This
1667 adds the dav and dav_fs modules, the SDBM library, and additional
1668 XML handling utilities. [Greg Stein]
1670 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
1673 *) Update the lib/expat-lite/ library (bring forward changes from
1674 the Apache 1.3 repository). [Greg Stein]
1676 *) If sizeof(long long) == sizeof(long), then prefer long in APR
1677 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
1679 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
1680 machines where sendfile is detected, but nobody has written ap_sendfile.
1681 [Dave Hill <ddhill@zk3.dec.com>]
1683 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
1685 *) ab would start up more connections than needed, then quit when the
1686 desired number were finished. Also fixed a logic error involving
1687 ab keepalives. [Victor J. Orlikowski]
1689 *) WinNT: Implement non-blocking pipes with timeouts to communicate
1690 with CGIs. Apache 2.0a4 had non-blocking pipes but without
1691 timeouts (i.e, if a timeout was specified, the pipe reverted to
1692 a full blocking pipe). Now the behaviour is more in line with
1693 Unix non-blocking pipes.
1696 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
1697 cache open file handles along with accept socket reuse enables
1698 Apache 2.0 to serve non-keepalive requests for static files at
1699 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
1700 and Apache 2.0 will serve almost 1200 rps on my system).
1703 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
1704 supports two config directives, mmapfile (same behavious as
1705 mod_mmap_static) and cachefile. Use the cachefile directive
1706 to cache open file handles. This directive only works on systems
1707 that have implemented the ap_sendfile API. cachefile works today
1708 on Windows NT, but has not been tested on any flavors of Unix.
1711 *) Cleanup the configuration. With the last few changes the
1712 configuration process automatically:
1713 inherits information about how to build from APR. Allowing
1714 APR to inform Apache that it should or should not use -ldl
1716 Detects which mod_cgi should be used mod_cgi or mod_cgid,
1717 based on the threading model
1719 Apache calls APR's configure process before finishing it's
1720 configuration processing, allowing for more information flow
1725 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
1726 with non-zero argument makes the socket non-blocking. BeOS and
1727 OS/2 already worked this way. [Jeff Trawick]
1729 *) ap_close() now calls ap_flush() for buffered files, so write
1730 operations work a whole lot better on buffered files.
1733 *) Fix error messages issued from MPMs which explain where to change
1734 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
1737 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
1738 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
1739 now the way that the blocking state of a pipe is manipulated.
1740 ap_block_pipe() is gone. [Jeff Trawick]
1742 *) Correct the problem where the only local host name that the IP stack
1743 can discover are 'undotted' private names. If no fully qualified
1744 domain name can be identified, the default ServerName will be set to
1745 the machine's IP address string. A warning is always provided if the
1746 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
1748 *) Repair problems with config file processing which caused segfault
1749 at init when virtual hosts were defined and which caused ServerName to
1750 be ignored when there was no valid DNS setup. [Jeff Trawick]
1752 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
1754 *) Add ap_sendfile implementation for AIX
1755 [Victor J. Orlikowski]
1757 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
1758 apr_network_io.h, and apr_thread_proc.h.
1759 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
1761 *) Bring the allocation and pool debugging code back into a working
1762 state. This will need to be tested as so far it's only been used on
1765 *) Change configuration command setup to be properly typesafe when in
1766 maintainer mode. Note that this requires a compiler that can initialise
1767 unions. [Ben Laurie]
1769 *) Turn on buffering for config file reads. Part of this was to
1770 repair buffered I/O support in Unix and implement buffered
1771 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
1773 *) Win32: Fix problem where UTC offset was not being set correctly
1774 in the access log. Problem reported on news group by Jerry Baker.
1777 *) Fix segfault when reporting this type of syntax error:
1778 "</container> without matching <container> section", where
1779 container is VirtualHost or Directory or whatever.
1782 *) Prevent the source code for CGIs from being revealed when using
1783 mod_vhost_alias and the CGI directory is under the document root
1784 and a user makes a request like http://www.example.com//cgi-bin/cgi
1785 as reported in <news:960999105.344321@ernani.logica.co.uk>
1788 *) Add support for the new Beos NetwOrking Environment (BONE)
1791 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
1792 final input char is incomplete; ap_bwrite_xlate() now handles
1793 incomplete final input chars. [Jeff Trawick]
1795 *) Yet another update to saferead/halfduplex stuff -- need to ensure
1796 that a bhalfduplex call occurs before logging or else DNS and
1797 such can delay the last packet of the response. [Dean Gaudet]
1799 *) Some syscall reduction in APR on unix -- don't seek when setting
1800 up an mmap; and don't fcntl() more than once per socket.
1803 *) When mod_cgid is started as root, the cgi daemon now switches
1804 to the configured User/Group (like other httpd processes)
1805 instead of continuing as root. [Jeff Trawick]
1807 *) The prefork MPM now uses an APR lock for the accept() mutex.
1808 It has not been getting a lock at all recently. httpd -V now
1809 displays APR's selection of the lock mechanism instead of the
1810 symbols previously respected by prefork. [Jeff Trawick]
1812 *) Change the mmap() feature test to check only for existence.
1813 The previous check required features not used by Apache.
1816 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
1817 sometimes mangled. The len parm to accept() was not
1818 initialized, leading sometimes to an endless loop of failed
1819 accept() calls on OS/390 and anywhere else that failed the call
1820 if the len was negative. Use <sys/un.h> for struct sockaddr_un
1821 instead of declaring it ourselves to fix a compilation problem
1822 on Solaris. [Jeff Trawick]
1824 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
1826 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
1828 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
1830 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
1831 initialization if ALLOC_DEBUG is defined; no known symptom
1832 otherwise. [Jeff Trawick]
1834 *) Fix typo in configure script when checking for mod_so. bash
1835 doesn't seem to have a problem but /bin/sh on Solaris does.
1836 Symptom: "./configure: test: unknown operator =="
1839 *) Rebind the Win32 NT and 9x services control into the MPM.
1840 All console, WinNT SCM and Win9x pseudo-service control code is
1841 now wrapped within the WinNT MPM.
1844 *) Make a copy of getenv("PATH") before storing for later use. Some
1845 getenv() implementations use the same storage for successive calls.
1846 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
1848 *) Server Tokens work in 2.0 again. This also propogates the change
1849 to allow just the product name in the server string using
1853 Changes with Apache 2.0a4
1855 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
1856 won't need to call it. [Greg Ames, Jeff Trawick]
1858 *) Move pre_config hook call to between configuration read and config
1859 tree walk. This allows all modules to implement pre_config hooks
1860 and know that they will be called at an appropriate time.
1863 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
1866 *) Add pre-config hooks back to all modules.
1869 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
1870 ContentDigest enabled and we can't/don't mmap the file.
1873 *) We now report the correct line number for syntax errors in config
1874 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
1876 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
1877 related bugs, and changed shmem/locking to use apr API. Shared-mem
1878 is currently disabled, however, because of problems with graceful
1879 restarts. [Ronald Tschalär]
1881 *) Fix corruption of IFS variable in --with-module= handling.
1882 Depending on the user's shell or customization thereof, there
1883 would be errors generating ap_config_auto.h later in the configure
1884 procedure. [Jeff Trawick]
1886 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
1887 isn't used (as in 1.3), except that on Unix it is now logged via
1888 ap_log_rerror() instead of by the child having STDERR_FILENO refer
1889 to the error log. [Greg Ames, Jeff Trawick]
1891 *) Add '-D' argument processing for run time configuration defines.
1894 *) Organize http_main.c as independent code, such that no code or
1895 global data is exported from it. WIN32 will dynamically link it
1896 to the server core, so this will prevent mutual dependency.
1899 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
1900 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
1903 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
1904 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
1906 *) Add mod_charset_lite for configuring character set translation.
1909 *) Add '-n' option to htpasswd to make it print its user:pw record
1910 on stdout rather than having to frob a text file. [Ken Coar]
1912 *) Fix saferead. Basically, we flush the output buffer if a read on the
1916 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
1917 a conversion is single-byte only. [Jeff Trawick]
1919 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
1920 the BeOS 5.0 documentation says that shutdown doesn't work yet.
1923 *) Fix some minor errors where pid was being manipulated as an int
1924 instead of the portable pid_t. [Roy Fielding]
1926 *) Fix some error log prints that were printing the pointer to a
1927 structure rather than the pid within the structure.
1928 [Jeff Trawick, Roy Fielding]
1930 *) ab: Fix a command-line processing bug; track bad headers in
1931 err_response; support reading headers up to 2K.
1932 [Ask Bjoern Hansen <ask@valueclick.com>]
1934 *) Fix ap_resolve_env() so that it handles new function added in a prior
1935 alpha (see "Added the capability to do ${ENVVAR} constructs in the
1936 config file.") as well as the constructs used by mod_rewrite.
1937 [Paul Reder <rederpj@raleigh.ibm.com>]
1939 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
1941 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
1942 APR to perform translation, instead of accessing the hard-coded tables
1943 in 1.3's ebcdic.c. [Jeff Trawick]
1945 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
1948 *) Add the ability to hook into the config file reading phase. Basically
1949 if a directive is specified EXEC_ON_READ, then when that directive is
1950 read from the config file, the assocaited function is executed. This
1951 should only be used for those directives that must muck with HOW the
1952 server INTERPRETS the config. This should not be used for directives
1953 that re-order or replace items in the config tree. Those changes should
1954 be made in the pre-config step.
1957 *) Add mod_example to the build system.
1960 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
1961 byte character sets. [Jeff Trawick]
1963 *) Pick up various EBCDIC fixes from 1.3 (from Martin
1964 Kraemer and Oliver Reh originally according to the change log).
1967 *) Fix a couple of problems in RFC1413 support (controlled by the
1968 IdentityCheck directive). Apache did not build the request string
1969 properly and more importantly Apache would loop forever if the
1970 would-be ident server dropped the connection before sending a
1971 properly terminated response. [Jeff Trawick]
1973 *) apxs works in 2.0.
1976 *) Reliable piped logs work in 2.0.
1979 *) Introduce a hash table implementation into APR to be used for
1980 replacing tables and other random data structures in Apache.
1983 *) Add some more error reporting to htpasswd in the case of problems
1984 generating or accessing the temporary file. Also, pass in a
1985 buffer if the implementation knows how to use it (i.e., if L_tmpnam
1986 is defined). [Ken Coar]
1988 *) Configure creates config.nice now containing your configure
1989 options. Syntax: ./config.nice [--more-options]
1992 *) Fix various return code problems in APR on Win32. For most of
1993 these, APR was returning APR_EEXIST instead of GetLastError()/
1994 WSAGetLastError(). [Jeff Trawick]
1996 *) Make piped logs work again in version 2.0
1999 *) Add VPATH support to UNIX build system of Apache and APR.
2002 *) Fix ap_tokenize_to_argv to respect the const arguments that are
2006 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
2007 Patch submitted to author.
2010 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
2011 /sbin in PATH on FreeBSD (all submitted to rse previously)
2014 *) Fix building Pthread-based MPMs on OpenBSD
2015 [Sascha Schumann] PR#26
2017 *) Fix ap_readdir() problem on systems where d_name[] field in
2018 struct dirent is declared with only one byte. (This problem only
2019 affected multithreaded builds.) This caused a segfault during
2020 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
2021 least). [Jeff Trawick]
2023 *) Fix some make-portability problems on at least Tru64, Irix
2025 [Sascha Schumann] PR#18, PR#39
2027 *) Add ap_sigwait() to support old-style sigwait() on systems
2028 like OS/390 and UnixWare.
2031 *) Add POSIX-thread flags for more platforms.
2034 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
2035 (on Unix, at least) to handle resolver errors. Fix a bug in
2036 the definition of APR_ENOMEM so that ap_strerror() can spit
2037 out the correct error message for it.
2040 Changes with Apache 2.0a3
2042 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
2045 *) API: *HOOK* macros now have an AP_ prefix
2048 *) Win32: Eliminate redundant calls to initialize winsock.
2049 [Tim Costello <timcostello@ozemail.com.au>]
2051 *) Fix bugs initializing ungetchar for pipes.
2052 [Chia-liang Kao <clkao@CirX.ORG>]
2054 *) The ab program in the src/support directory is now portable using
2058 *) Support directory is being compiled when the server is built
2061 *) The configure option --with-program-name has been added to allow
2062 developers to rename the executable at configure time. This also
2063 changes the name of the config files to match the executable's name.
2066 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
2067 containing version numbers. [Martin Pool]
2069 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
2070 Unix; access_log and error_log now created with these perms; non-
2071 Unix is unaffected [Jeff Trawick]
2073 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
2074 Replaced more magic numbers with MD5_DIGESTSIZE.
2075 [William Rowe, Roy Fielding]
2077 *) Win32: Get mod_auth_digest compiling and added to the Windows
2078 build environment. Not tested and I'd be suprised if it
2079 actually works. [Bill Stoddard]
2081 *) Revamp the Win32 make environment. Makefiles have been removed and
2082 Apache.dsw created to bring together all the pieces. Create new file
2083 os/win32/BaseAddr.ref to define module base addresses (to prevent
2084 dll relocation at start-up).
2085 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
2087 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
2088 of the \015, \012, and \015\012 constants with macros.
2089 [Greg Ames <gregames@us.ibm.com>]
2091 *) Add ap_xlate_open() et al for translation of text between different
2092 character sets. The initial implementation requires iconv().
2095 *) More FAQs and answers from comp.infosystems.www.servers.unix.
2096 [Joshua Slive <slive@finance.commerce.ubc.ca>]
2098 *) CGI output is being timed out now.
2101 *) Fix the problem with dieing quietly. dupfile now takes a pool which
2102 is used by the new apr file. There is no reason to create a new file
2103 with the same lifetime as the original file.
2106 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
2107 module base addresses. This will help shooting seg faults
2108 in the field. [William Rowe <wrowe@lnd.com>]
2110 *) Update Apache on Windows documentation. Add new document
2111 describing how to compile Apache on Windows.
2112 [William Rowe <wrowe@lnd.com>]
2114 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
2115 microseconds instead of seconds. Some storage leaks and other
2116 minor bugs in related code were fixed. [Jeff Trawick]
2118 *) Win32: First cut at getting mod_isapi working under 2.0
2119 [William Rowe <wrowe@lnd.com>]
2121 *) First stab at getting mod_auth_digest working under 2.0
2122 quick change summary:
2123 - moved the random byte generation (ap_generate_random_bytes) into APR
2124 - now uses ap_time_t
2125 - compiles and runs on linux
2127 [Brian Martin <bmartin@penguincomputing.com>]
2129 *) Win32: Move the space stripping of physical service names
2130 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
2131 unresolved symbol. Add dependency checking to the
2132 CreateService call to ensure TCPIP and AFP (winsock) is started
2134 [William Rowe <wrowe@lnd.com>]
2136 *) Win32: Add code to perform latebinding on functions that may
2137 not exist on all levels of Windows where Apache runs. This
2138 is needed to allow Apache to start-up on Win95/98. All calls
2139 to non portable functions should be protected with
2140 ap_oslevel checks to prevent runtime segfaults.
2141 [William Rowe <wrowe@lnd.com>]
2143 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
2145 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
2147 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
2148 This addresses PR 1623. Still need to address timing out runaway
2149 CGI scripts. [Bill Stoddard]
2151 *) Win32: Make ap_stat Windows 95/98 friendly
2152 [William Rowe <wrowe@lnd.com>]
2154 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
2155 always fail. Need to initialise the dwOSVersionInfoSize member of the
2156 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
2159 The patch also enhances ap_get_oslevel (and the associated enum) to
2160 handle selected service packs for NT4, and adds recognition for
2161 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
2162 we can use ReadFileScatter and WriteFileGather in readwrite.c.
2163 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
2165 *) Get mod_rewrite building and running, and mod_status building for Win NT
2166 [Allan Edwards <ake@raleigh.ibm.com>]
2168 *) Patch to port mod_auth_db to the 2.0 api and also to support
2169 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
2170 2.7.7. It should work with version 1 as well but I haven't tested it.
2171 [Brian Martin <bmartin@penguincomputing.com>]
2173 *) Get APR DSO code working under Windows. Includes cross platform
2175 [Tim.Costello@BTFinancialgroup.com]
2177 *) Fix some of the Windows APR time functions.
2180 *) FAQ changes related to tidying up historical documents on the web site.
2181 [Joshua Slive <slive@finance.commerce.ubc.ca>]
2183 *) Move Windows DSO code into APR.
2186 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
2187 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
2188 at build time. At this point, the server will not compile on Windows because
2189 of the recent DSO commits. Fixing those next.
2190 [Bill Rowe & Bill Stoddard]
2192 *) Added error checking for file I/O APR routines.
2193 [Jon Travis <jtravis@covalent.net>]
2195 *) APR: Don't use the values of resolver error codes for the
2196 corresponding APR error codes. On Unix and Win32, return the
2197 proper APR error code after a resolver error. [Jeff Trawick]
2199 Changes with Apache 2.0a2
2201 *) Renamed the executable back to httpd on all platforms other
2205 *) Allow BeOS to survive restarts, log properly and a few
2206 small things it had problems with due to the way it setup
2207 users and groups. [David Reid]
2209 *) Get mod_rewrite working with APR locks
2210 [Paul Reder <rederpj@raleigh.ibm.com>]
2212 *) Actually remove the sempahore when the lock cleanup routine
2213 is called on BeOS. [David Reid]
2215 *) Clear hook registrations between reads of the config file.
2216 When DSOs are unloaded and re-loaded the old hook pointers may
2217 no longer be valid. This fix eliminates potential segfaults.
2218 [Allan Edwards <ake@raleigh.ibm.com>]
2220 *) Fix a problem with Sigfunc not being defined or bypassed
2221 if sigaction() wasn't found. [Jim Jagielski]
2223 *) Fix the locking mechanism on BSD variants. They now use fcntl
2224 locks. This allows the server to start and serve pages.
2227 *) First cut at getting the Win32 installer to work
2228 [William Rowe <wrowe@lnd.com>]
2230 *) Get htpasswd compiling under Windows
2231 [William Rowe <wrowe@lnd.com>]
2233 *) Change the log message for a bind() failure to show the
2234 interface and port number. [Jeff Trawick]
2236 *) Import the documentation from 1.3.12 and bring parts of it
2237 up-to-date with respect to the changes that have occurred
2241 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
2242 now logged correctly on BeOS.
2245 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
2246 Makefile.win includes the same user interface as the old
2248 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
2250 *) Win32 exec now uses COMSPEC environment string for command
2251 shell path resolution.
2252 [William Rowe <wrowe@lnd.com>] PR#3715
2254 *) Win32: ap_connect() was not returning correct error condition
2256 [Allen Prescott <allen@clanprescott.com>]
2258 *) Win32: ap_open() was broken on Win9x because an NT-specific
2259 flag was passed to CreateFile. ap_puts() added an unnecessary
2261 [Jeff Trawick <trawick@us.ibm.com>]
2263 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
2264 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
2265 confusing ee/et name and made all extensions language/dialect
2266 rather than country reflecting. Changed example files to
2267 explicit reflect the ISO charset and added a few common
2268 ones to the example config [dirkx]
2270 *) Extend external module capability. To use this, you call
2271 configure with --with-module=path/to/mod1,path/to/mod2,etc.
2274 *) Backported the various "default charset" fixes from 1.3.12,
2275 including the AddDefaultCharset directive. [Jim Jagielski]
2277 *) Added the capability to do ${ENVVAR} constructs in the
2278 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
2279 it does this on a line by line basis; i.e. if the envvar
2280 expands to something with spaces you have to protect it
2281 by adding quotes around it (Unless of course you expect it
2282 to contains more than one argument. Alternatively you
2283 can compile it on a per token basis; which is what people
2284 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
2285 hampers fancier hacks.
2286 [Dirk-Willem van Gulik]
2288 *) Changed the 'ErrorDocument' syntax in that it NO longer
2289 supports the asymetric
2291 ErrorDocument 301 "Some message
2293 Note the opening " quote, without a closing quote. It now
2294 has either the following syntaxes
2296 ErrorDocument XXX /local/uri
2297 ErrorDocument XXX http://valid/url
2298 ErrorDocument XXX "Some Message"
2300 The recognition heuristic is: if it has a space it
2301 is a message. If it has no spaces and starts with a /
2302 or is a valid URL then treat it that way. Otherwise it
2303 is assumed to be a message.
2305 This breaks backward compatibility but makes live a hell
2306 of a lot easier for GUI's and config file parsers.
2307 [Dirk-Willem van Gulik]
2309 *) Changed 'CacheNegotiatedDocs' from its present/not-present
2310 syntax into a 'on' or 'off' syntax. As it currently is the
2311 only non nesting token which uses NO_ARGS and thus is an
2312 absolute pain for any config interface automation. This
2313 breaks backward compatibility. [Dirk-Willem van Gulik]
2315 *) Add ability to add external modules to the build process. This is
2316 done with --with-module=/path/to/module. Modules can only be added
2317 as static modules at this point.
2320 Changes with Apache 2.0a1
2322 *) Fix FreeBSD 3.3 core dump.
2323 Basically, ap_initialize() needs to get called before
2324 create_process(), since create_process() passes op_on structure
2325 to semop() to get a lock, but op_on isn't initialized until
2326 ap_initialize() calls setup_lock(). Here is a slight
2327 rearrangement to main() which calls ap_initialize() earlier...
2328 [Jeff Trawick <trawick@us.ibm.com>]
2330 *) Enable Apache to use sendfile/TransmitFile API
2331 [Bill Stoddard, David Reid, Paul Reder]
2333 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
2337 *) Make file I/O and network I/O writev/sendv APIs consistent.
2338 Eliminate use of ap_iovec_t and use Posix struct iovec.
2339 Use seperate variable on ap_writev to set the number of iovecs
2340 passed in and number of bytes written.
2343 *) Adapt file iol to use APR functions. Replaced ap_open_file()
2344 with ap_create_file_iol(). ap_create_file_iol() requires that
2345 the file be opened prior to the call using ap_open().
2348 *) Port mod_include and mod_cgi to 2.0
2349 [Paul Reder, Bill Stoddard]
2351 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
2352 bytes_read/bytes_written is always valid (never -1). Plus
2353 some fixes to buff.c to correct problems introduced by the
2354 errno => ap_status_t changes a while back. Plus a fix to
2355 chunked encoding introduced right at the beginning of 2.0.
2358 *) Revamped UNIX build system to use autoconf and libtool.
2359 [Manoj Kasichainula, Sascha Schumann]
2361 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
2363 *) More rigorous checking of Host: headers to fix security problems
2364 with mass name-based virtual hosting (whether using mod_rewrite
2365 or mod_vhost_alias).
2366 [Ben Hyde, Tony Finch]
2368 *) Add back support for UseCanonicalName in <Directory> containers.
2369 [Manoj Kasichainula]
2371 *) Added APLOG_STARTUP log type. This allows us to write an error
2372 message without any of the date and time information. As a part
2373 of this change, I also removed all of the calls to fprintf(stderr
2374 and replaced them with calls to ap_log_error using APLOG_STARTUP
2375 writing to stderr is no longer portable, because we don't direct
2376 stderr to the error log on all platforms.
2379 *) Convert error logging functions to take errno as an argument.
2380 This makes our error logs more portable, because some Windows API's
2381 don't set errno. This change allows us to still output a valid
2382 message on all of our platforms.
2385 *) mod_mime_magic runs in 2.0-dev now.
2386 [Paul Reder <rederpj@raleigh.ibm.com>]
2388 *) sendfile has been added to APR.
2389 [John Zedlewski <zedlwski@Princeton.EDU>]
2391 *) buff.c has been converted to no longer use errno.
2392 [Manoj Kasichainula]
2394 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
2395 interface adaption to APR functions did it. [Martin Kraemer]
2397 *) Support DSOs properly on 32-bit HP-UX 11.0
2398 [Dilip Khandekar <dilip@cup.hp.com>]
2400 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
2401 [Ralf S. Engelschall]
2403 *) Cleaned APR build environment integration and bootstrap APR
2404 automatically for developers from src/Configure.
2405 [Ralf S. Engelschall]
2407 *) Fixed building of src/support/htpasswd.c
2408 [Ralf S. Engelschall]
2410 *) When generating the Location: header, mod_speling forgot
2411 to escape the spelling-fixed uri. (Forw-Port from 1.3)
2414 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
2416 *) Change all pools to APR contexts. This is the first step to
2417 incorporating APR into Apache. [Ryan Bloom]
2419 *) Move "handler not found" warning message to below the check
2420 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
2421 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
2423 *) Support line-continuation feature in config.option file and
2424 allow the loading of multiple option sections at once via
2425 ``--with-option=<section1>,<section2>,...''
2426 [Ralf S. Engelschall]
2428 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
2430 Changes with Apache MPM
2432 *) Use asynchronous AcceptEx() and a completion port to accept and
2433 dispatch connections to threads in Windows NT/2000.
2436 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
2439 *) Implement the APACI --with-option facility
2440 (per default used the config.option file).
2441 [Ralf S. Engelschall]
2443 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
2445 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
2446 Replace pre_connection module call with a register_hook call and
2447 implement pre_connection as a hook. The intent is that these hooks will
2448 be extended to allow Apache to be multi-protocol, and also to allow the
2449 calling order to be specified on a per-hook/per-module basis.
2452 *) Implement mpm_* methods as "modules". Each method gets its own
2453 subdir in src/modules (eg: src/modules/prefork). Selection
2454 of method uses Rule MPM_METHOD. [Jim Jagielski]
2456 *) Port the hybrid server from the apache-apr repository as
2457 mpm_mpmt_pthread. [Manoj Kasichainula]
2459 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
2460 amongst the unix MPMs.
2462 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
2463 signal handling for the new world order. [Dean Gaudet]
2465 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
2466 of alloc.c for now. [Dean Gaudet]
2468 *) Handle partial large writes correctly. [Ben Laurie]
2470 *) Eliminate conn_rec's pointer to server. All it knows is the base server
2471 based on IP/port. [Ben Laurie]
2473 *) Port a bunch of modules to the new module structure.
2474 ["Michael H. Voase" <mvoase@midcoast.com.au>]
2476 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
2478 *) Basic restructuring to introduce the MPM concept; includes various
2479 changes to the module API... better described by
2480 docs/initial_blurb.txt. [Dean Gaudet]
2482 Changes with Apache pthreads
2484 *) New buff option added: BO_TIMEOUT. It describes the timeout for
2485 buff operations (generally over a network).
2486 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
2488 *) Created http_accept abstraction. Added 4 new functions (not exported):
2489 init_accept(), begin_accepting_requests(), get_request(),
2490 stop_accepting_requests() [Bill Stoddard]
2492 *) Fix to ap_rprintf call that allows mod_info to work properly.
2493 [James Morris <jmorris@intercode.com.au>]
2495 *) user and ap_auth_type fields were moved from connection_rec to
2496 request_rec. [Ryan Bloom]
2498 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
2499 needed in a threaded server.
2501 *) Initial pthread implementation from from Dean's apache-nspr code.
2502 [Bill Stoddard, Ryan Bloom]
2505 Changes with Apache 1.3.9
2507 *) Remove bogus error message when a redirect doesn't set Location.
2508 Instead, use an empty string to avoid coredump if the error message
2509 was supposed to include a location. [Roy Fielding]
2511 *) Don't allow configure to include mod_auth_digest unless it is
2512 explicitly requested, even if the user asked for all modules.
2515 *) Translate module names to dll names for OS/2 so that they are no more
2516 than 8 characters long and have an extension of "dll" instead of "so".
2519 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
2520 Fix test-compile check to check for randbyte instead of trand32.
2521 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
2522 and tweak to make Amaya happier. [Ronald Tschalär]
2524 *) Ensure that the installed expat include files are world readable,
2525 just like the other header files. [Martin Kraemer]
2527 *) Fixed generated AddModule adjustments in APACI's `configure' script
2528 in order to allow (new) modules like mod_vhost_alias to be handled
2529 correctly (which was touched by the adjustments for mod_alias).
2530 [Ralf S. Engelschall]
2532 *) For binary builds, add -R flag to apachectl to work around the lack of
2533 an absolute path to the ./libexec directory where the libhttp.ep file
2534 is needed for SHARED_CORE architectures. [Randy Terbush]
2536 *) WIN32: Create the CGI script process as DETACHED. This may solve the
2537 problem observed by some Win95/98 users where they get CGI script
2538 output sent to the console. [Bill Stoddard]
2540 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
2541 routines are now called ap_base64* and are 'plain' (i.e., no
2542 pool access or anything clever). Inside util.c the routines acting
2543 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
2544 The oddly named ap_uuencode(), ap_uudecode() are kept around for
2545 now but deprecated. [dirkx]
2547 *) Clean up the base64 and SHA1 additions and make sure they are
2548 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
2549 files. [Roy Fielding]
2551 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
2552 checking. Allow compiling on VS 6.0. [Randy Terbush]
2554 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
2556 *) Use TestCompile to search for the truerand library (rather than blindly
2557 assuming its existence). If it is not found, complain (but do not
2558 exit - yet). [Martin Kraemer]
2560 *) We forgot to add the new exported function names to
2561 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
2563 *) Add description of -T command-line option to usage().
2564 [Ralf S. Engelschall]
2566 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
2567 searched only AFTER libap has been searched, because libap needs
2568 some symbols from libos. [Martin Kraemer]
2570 *) Fix conflict with original mod_digest related to the symbol of the
2571 module dispatch list (which has to be unique for DSO and follow the
2572 usual conventions for the installation procedure).
2573 [Ralf S. Engelschall]
2575 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
2576 for other platforms as well. [Martin Kraemer]
2578 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
2579 types by AP_LONG and replace reference to renamed variable 'ubuf'
2580 by 'buffer'. [Martin Kraemer]
2582 Changes with Apache 1.3.8 [not released]
2584 *) Flush the output buffer immediately after sending an error or redirect
2585 response, since the result may be needed by the client to abort a
2586 long data transfer or restart a series of pipelined requests.
2587 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
2589 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
2590 [Ian Turner <iant@sequent.com>] PR#4735
2592 *) Local struct mmap in http_core.c conflicted with system structure
2593 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
2595 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
2596 [Ronald Tschalär <ronald@innovation.ch>]
2598 *) Fix a memory leak where the module counts were getting messed
2599 up across restarts. [David Harris <dharris@drh.net>]
2601 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
2602 properly in mod_access.
2603 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
2605 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
2606 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
2608 *) PORT: Support for compaq/tandem/com.
2609 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
2611 *) Added SHA1 password encryption support to easy migration from
2612 Netscape servers. See support/SHA1 for more information.
2613 Caused the separation of ap_md5.c into md5, sha1 and a general
2614 ap_checkpass.c with just a validate_passwd routine. Added a
2615 couple of flags to support/htpasswd. Some reuse of the to64()
2616 function; hence renamed to ap_to64().
2617 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
2619 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
2620 with ASCII/EBCDIC conversions in "ident" query.
2621 [David McCreedy <McCreedy@us.ibm.com>]
2623 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
2624 Change "Power Macintosh" to Power* so if uname prints "Power Book"
2625 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
2627 *) Fix SIGSEGV on some systems because the Vary fix below included
2628 a call to table_do with a variable argument list that was not
2629 NULL terminated. Replaced with better implementation. [Roy Fielding]
2631 Changes with Apache 1.3.7 [not released]
2633 *) The "Vary" response header field is now sanitised right before
2634 the header is sent back to the client. Multiple "Vary" fields
2635 are combined, and duplicate tokens (e.g., "Vary: host, host" or
2636 "Vary: host, negotiate, host, accept-language") are reduced to
2637 single instances. This is a better solution than the force-no-vary
2638 one (which is still valid for clients that can't cope with Vary
2639 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
2641 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
2643 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
2644 least on Linux and FreeBSD for now.
2647 *) Win32: More apache -k restart work. Restarts are now honored
2648 immediately and connections in the listen queue are -not- lost.
2649 This is made possible by the use of the WSADuplicateSocket()
2650 call. The listeners are opened in the parent, duplicated, then
2651 the duplicates are passed to the child. The original listen sockets
2652 are not closed by the parent across a restart, thus the listen queue
2654 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2656 *) Fix handling of case when a client has sent "Expect: 100-continue"
2657 and we are going to respond with an error, but get stuck waiting to
2658 discard the body in the pointless hope of preserving the connection.
2659 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
2661 *) Fix 'configure' to work correctly with SysV-based versions of
2662 'tr' (consistent with Configure's use as well). [Jim Jagielski]
2664 *) apxs: Add "-S var=val" option which allows for override of CFG_*
2665 built-in values. Add "-e" option which works like -i but doesn't
2666 install the DSO; useful for editing httpd.conf with apxs. Fix
2667 editing code so that multiple invocations of apxs -a will not
2668 create duplicate LoadModule/AddModule entries; apxs can now be
2669 used to re- enable/disable a module. [Wilfredo Sanchez]
2671 *) Win32: Update the server to use Winsock 2. Specifically, link with
2672 ws2_32.lib rather than wsock32.lib. This gives us access to
2673 WSADuplcateSocket() in addition to some other enhanced comm APIs.
2674 Win 95 users may need to update their TCP/IP stack to pick up
2675 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
2676 [Bill Stoddard stoddard@raleigh.ibm.com]
2678 *) Win32: Redirect CGI script stderr (script debug info) into the
2679 error.log when CGI scripts fail. This makes Apache on Win32
2680 behave more like Unix.
2681 [Bill Stoddard stoddard@raleigh.ibm.com]
2683 *) Fixed `httpd' usage display: -D was missing.
2684 [Ralf S. Engelschall] PR#4614
2686 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
2687 [Ralf S. Engelschall] PR#4561, PR#4562
2689 *) OS/2: Fix problem with accept lock semaphores where server would die with
2690 "OS2SEM: Error 105 getting accept lock. Exiting!"
2691 [Brian Havard] PR#4505
2693 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
2694 [Randy Terbush <randy@covalent.net>]
2696 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
2697 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
2699 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
2700 command potentially _is_ GCC. [Ralf S. Engelschall]
2702 *) Fix apxs build issues on AIX
2703 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
2705 *) DocumentRoot Checking: Under previous versions, when Apache
2706 first started up, it used to do a stat of each DocumentRoot to
2707 see if it existed and was a directory. If not, then an error
2708 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
2709 does not exist, you will get error messages in error_log. If
2710 the '-t' command line option is used (to check the configuration)
2711 the check of DocumentRoot IS performed. An additional command
2712 line option, '-T', has been added if you want to avoid the
2713 DocumentRoot check even when checking the configuration.
2716 *) Win32: The query switch "apache -S" didn't exit after showing the
2717 vhost settings. That was inconsistent with the other query functions.
2718 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
2720 *) Win32: Changed behaviour of apache -k restart.
2721 Previously, the server would drain all connections in the stack's
2722 listen queue before honoring the restart. On a busy server, this
2723 could take hours. Now, a restart is honored almost immediately.
2724 All connections in Apache's queues are handled but connections in
2725 the stack's listen queue are discarded. Restart triggered by
2726 MaxRequestPerChild is unchanged.
2727 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2729 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
2730 the accept loop. Good for a 5% performance boost. Cleaned up
2731 parent/child process management code.
2732 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2734 *) Added ceiling on file size for memory mapped files.
2735 [John Giannandrea <jg@meer.net>] PR#4122
2737 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
2738 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
2739 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
2741 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
2742 use this at least for Expat. [Ralf S. Engelschall]
2744 *) Allow .module files to specify libraries with Lib:.
2747 *) Allow SetEnvIf[NoCase] to test environment variables as well
2748 as header fields and request attributes. [Ken Coar]
2750 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
2751 content-types are "text/html;parameters". PR#4524 [Ken Coar]
2753 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
2754 never accepted into any standard, and it opens up certain DoS
2755 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
2757 *) TestCompile updated. We can now run programs and output the
2758 results during the Configure process. [ Jim Jagielski]
2760 *) The source is now quad (long long) aware as needed. Specifically,
2761 the Configure process determines the correct size of off_t and
2762 *void. When the OS/platform/compiler supports quads, ap_snprintf()
2763 provides for the 'q' format qualifier (if quads are not available,
2764 'q' is silently "demoted" to long). [Jim Jagielski]
2766 *) When the username or password fed to htpasswd is too long, include the
2767 size limit in the error message. Also report illegal characters
2768 (currently only ':') in the username. Add the size restrictions
2769 to the man page. [Ken Coar]
2771 *) Fixed the configure --without-support option so it doesn't result in
2772 an infinite loop. [Marc Slemko]
2774 *) Piped error logs could cause a segfault if an error occured
2775 during configuration after a restart.
2776 [Aidan Cully <aidan@panix.com>] PR#4456
2778 *) If a "Location" field was stored in r->err_headers_out rather
2779 than r->headers_out, redirect processing wouldn't find it and
2780 the server would core dump on ap_escape_html(NULL). Check both
2781 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
2782 if Location isn't set. [Doug MacEachern, Ken Coar]
2784 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
2785 of the Expat 1.0.2 distribution. [Greg Stein]
2787 *) Replace regexec() calls with calls to a new API stub function
2788 ap_regexec(). This solves problems with DSO modules which use the regex
2789 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
2791 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
2792 environment variables can be set according to the protocol version
2793 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
2795 *) Add DSO support for OpenStep (Mach 4.2) platform.
2796 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
2798 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
2799 [Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
2801 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
2802 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
2804 *) Better DSO flags recognition on NetBSD platforms using ELF.
2805 [Todd Vierling <tv@pobox.com>] PR#4310
2807 *) Always log months in english format for %t in mod_log_config.
2808 [Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
2810 *) Support for server-parsed and multiview-determined ReadmeName and
2811 HeaderName files in mod_autoindex. Removed the restriction on
2812 "/"s in ReadmeName and HeaderName directives since the *sub_req*
2813 routines will deal with the access issues. (It's now possible to
2814 have {site|group|project|customer|...} wide readmes and headers.)
2815 [Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
2818 *) When stat() fails, don't assume anything about the contents of
2819 the struct stat. [Ed Korthof <ed@bitmechanic.com>]
2821 *) It's OK for a semop to return EINTR, just loop around and try
2822 again. [Dean Gaudet]
2824 *) Fix configuration engine re-entrant hangups, which solve a
2825 handful of problems seen with mod_perl <Perl> configuration sections
2826 [Salvador Ortiz Garcia <sog@msg.com.mx>]
2828 *) Mac OS and Mac OS X Server now use the appropriate custom layout
2829 by default when building with APACI; allow for platform-specific
2830 variable defaults in configure. [Wilfredo Sanchez]
2832 *) Do setgid() before initgroups() in http_main; some platforms
2833 zap the grouplist when setgid() is called. This was fixed in
2834 suexec earlier, but the main httpd code missed the change.
2835 [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2579
2837 *) Add recognition of .tgz as a gzipped tarchive.
2838 [Bertrand de Singly <bertrand.de-singly@polytechnique.fr>] PR#2364
2840 *) mod_include's fsize/flastmod should allow only relative paths, just
2841 like "include file". [Jaroslav Benkovsky <benkovsk@pha.pvt.cz>]
2843 *) OS/2: Add support for building loadable modules using DLLs.
2846 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
2849 *) Fix minor but annoying bug with the test for Configuration.tmpl
2850 being newer than Configuration so that it is less likely to fail
2851 when using APACI and shadow sources. [Wilfredo Sanchez]
2853 *) PORT: Add initial support for Mac OS (versions 10.0 and
2854 greater). Use Mac OS X Server layout for now. Clean up dyld code
2855 in unix/os.c, and don't install the dyld error handlers, which
2856 are no longer needed in Mac OS. [Wilfredo Sanchez]
2858 *) Rename Rhapsody layout to "Mac OS X Server". Change install
2859 locations to appropriate ones for user-built (as opposed to
2860 system) installs. [Wilfredo Sanchez]
2862 *) Modify mod_autoindex's handling of AddDescription so that the
2863 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
2865 *) Add functionality to the install-bindist.sh script created by
2866 binbuild.sh to use tar when copying distribution files to the
2867 serverroot. This allows upgrading an existing installation
2868 without nesting the new distribution in the old.
2870 install-bindist.sh now detects the local perl5 path to install
2871 apxs and dbmmanage with proper path to perl interpreter.
2873 Add an install-binsupport target which copies the source files
2874 for apxs and dbmmanage to bindist to allow these scripts to
2875 be properly installed relative to the destination serverroot.

2901 *) Fixed a bug in mod_dir that causes a child process will infinitely
2902 recurse when it attemps to handle a request for a directory wnd the
2903 value of the DirectoryIndex directive is a single dot. Also likely
2904 to happen for anyother values of DirectoryIndex that will map back
2905 to the same directory. The handler now only considers regular files

2992 htpasswd utility was limiting passwords to only 8 characters.
2995 *) EBCDIC platforms: David submitted patches for two bugs in the
2996 MD5 digest port for EBCDIC machines:
2997 a) the htdigest utility overwrote the old contents of the digest file
2998 b) the Content-MD5 header value (ContentDigest directive) was wrong
2999 when the returned file was not converted from EBCDIC, but was a
3000 binary (e.g., image file) in the first place.
3001 [David McCreedy <mccreedy@us.ibm.com>]
3003 *) support/htpasswd now permits the password to be specified on the

3008 *) Win32: Win32 multiple services patch. Added capability to install and
3009 run multiple copies of apache as individual services.

3039 mismatches were causing compilation problems with gcc -pedantic and
3040 in the TPF cross-compilation. [Ken Coar]
3042 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
3043 a roughly 5 fold speed up. [Brian Havard]
3045 *) proxy ftp: instead of using the hardwired string "text/plain" as
3046 a fallback type for files served by the ftp proxy, use the
3047 ap_default_type() function to determine the configured type.
3048 This allows for special configurations like
3049 <Directory proxy:ftp://some.host>
3050 DefaultType gargle/blurb
3052 Additionally, add the Content-Encoding: header to FTP proxy replies
3053 when the encoding is defined (by the AddEncoding directive).
3054 Because it was missing, it was almost impossible to browse compressed
3055 files using the FTP proxy (works now perfectly in Communicator).
3056 The ftp proxy now also returns the Date: and Server: header lines (if not
3057 much else... This code is "somewhat" broken) like normal requests do.
3060 *) Be more smart in APACI's configure script when determining the UID/GID
3061 for User/Group directives and use the determined UID/GID to initialize
3062 the permissions on the proxycachedir.
3063 [Dirk-Willem van Gulik, Ralf S. Engelschall]
3065 *) Changed the forking-prior-to-cleanup in the proxy module to first

3067 the number of fork()s from one/request to just the odd one an hour.
3068 [Dirk-Willem van Gulik]

3081 (for instance from an APACI configure --sysconfdir=/etc/httpd/conf

3097 *) M_INVALID needed a value within the scope of METHODS so that unknown
3098 methods can be access controlled. [Roy Fielding] PR#3821
3100 *) Added PassAllEnv; makes server's entire environment available
3101 to CGIs and SSIs executed within directive's scope. [Ken Coar]
3103 *) ap_uuencode() always added two trailing '='s and encoding of
3104 8 bit characters on a machine with signed char may produced
3105 incorrect results. Additionally ap_uuencode() should now
3106 work correctly on EBCDIC platforms.
3107 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
3109 *) WIN32: Binary installer now runs the configuration DLL before
3110 the reboot prompt (which is only given if MSVCRT.DLL system
3111 DLL is new or updated). This should avoid the configuration
3112 directory being empty after installation. [Paul Sutton]
3113 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988

3117 the Apache service on NT. [Paul Sutton] PR#3741
3119 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
3121 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
3122 have been reported with flock() locking (probably related to kernel
3123 version). [Dean Gaudet] PR#2723, 3531

3136 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
3137 for 8-bit safeness. [Dean Gaudet]
3139 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
3140 because SPARCs have a small machine-specific maximum size for the Global
3141 Offset Table which is often exceeded when compiling one of the larger
3142 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
3144 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
3145 DSO/DLL section because it's a directive from mod_status and isn't
3146 available before the DLL of mod_status is loaded.

3161 *) Let APACI's configure script correctly complain for unknown --enable-XXX
3162 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
3164 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
3165 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
3166 possible buffer overflows. [Ralf S. Engelschall]
3168 *) Remove no longer used non-API function ap_single_module_init().
3169 [Ralf S. Engelschall]
3171 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
3174 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
3175 to make platform installations easier. [Wilfredo Sanchez]
3177 *) In configure, do not append the target name to the directory path if
3178 the path already contains "apache". [Ralf S. Engelschall]
3180 *) SIGPIPE is now ignored by the server core. The request write routines
3181 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
3182 correctly check for output errors and mark the connection as aborted.
3183 Replaced many direct (unchecked) calls to ap_b* routines with the
3184 analogous ap_r* calls. [Roy Fielding]
3186 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
3187 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
3188 Furthermore map lookups for non-existent keys are now cached as well.
3189 Additionally "txt" maps are now parsed with simple string functions
3190 instead of using ap_pregcomp(). As a side effect a bug that prevented
3191 the usage of keys containing the "," character was fixed.
3192 The changes drastically improve the performance when large rewrite maps
3194 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
3196 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
3197 other than GET, and const'd the definition of method in request_rec.
3200 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
3202 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
3203 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
3205 *) Add %V to mod_log_config, this logs the hostname according to the
3206 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
3207 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
3209 *) Add support for \n and \t to mod_log_config, can be used to produce
3210 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
3212 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
3214 *) Added informative error messages for failed munmap() and fseek() calls
3215 in http_core.c. [John Bley, Roy Fielding]
3217 *) Added some informative error messages for some failed malloc()
3218 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
3220 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
3221 is removed. This allows <Directory proxy:*> directives to work and
3222 prevents invalid requests from killing the process.
3223 [Brian Havard <brianh@kheldar.apana.org.au>]
3225 *) Reorganised FAQ document.
3226 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497
3228 *) src/support/: The ApacheBench benchmark program was overhauled by
3229 David N. Welton: you can now have it generate an HTML TABLE, presumably
3230 for integration into other HTML sources. David updated the ab man page
3231 as well and added some missing descriptions. Thanks!
3232 [David N. Welton <davidw@prosa.it>]
3234 *) Win32: The filename validity checker now allows filenames containing
3235 characters in the range 0x80 to 0xff (for example accented characters).
3236 [Paul Sutton] PR#3890
3238 *) Added conditional logging based upon environment variables to
3239 mod_log_config. mod_log_referer and mod_log_agent
3240 are now deprecated. [Ken Coar]
3242 *) Allow apache acting as a proxy server to relay the real
3243 reason of a failure to a client rather than the "internal
3244 server error" it does currently. The general exposure mechanism
3245 can be triggered by any module by setting the "verbose-error-to"
3246 note to "*"; this allows more than just proxy errors to be exposed.
3247 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
3249 *) Moved man pages for ab and apachectrl to section 8.
3250 [Wilfredo Sanchez, Roy Fielding]
3252 *) Added -S option to install.sh so that options can be passed to
3253 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
3255 *) Tweak modules Makefile generated by Configure so that it handles
3256 the test case of no modules being selected. [chaz@reliant.com]
3258 *) Added a <LimitExcept method ...> sectioning directive that allows
3259 the user to assign authentication control to any HTTP method that
3260 is *not* given in the argument list; i.e., the logical negation
3261 of the <Limit> directive. This is particularly useful for controlling
3262 access on methods unknown to the Apache core, but perhaps known by
3263 some module or CGI script. [Roy Fielding, Tony Finch]
3265 *) Prevent apachectl from complaining if the PIDFILE exists but
3266 does not contain a process id, as might occur if the server is
3267 being rapidly restarted. [Wilfredo Sanchez]
3269 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
3271 *) Entity tag comparisons for If-Match and If-None-Match were not being
3272 performed correctly -- weak tags might cause false positives. Also,
3273 strong comparison wasn't properly enforced in all cases.
3274 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
3276 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
3279 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
3280 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
3282 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
3283 to util.c for parsing an HTTP header field value to extract the next
3284 list item, taking into account the possible presence of nested comments,
3285 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
3286 insignificant whitespace and lowercases non-quoted tokens.
3287 [Roy Fielding] PR#2065
3289 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
3290 code different from 500. This allows the proxy to, e.g., return
3291 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
3293 *) Fix ordering of language variants for the case where the traditional
3294 negotiation algorithm is being used with multiple language variants
3295 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
3297 *) Do not round the TCN quality calculation to 5 decimal places,
3298 unlike RFC 2296, because the calculation might need 12 decimal places
3299 to get the right result. [Roy Fielding]
3301 *) Remove unused code to disable transparent negotiation when
3302 negotiating on encoding only, as we now handle encoding too
3303 (though this is nonstandard for TCN), remove charset=ISO-8859-1
3304 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
3305 some debugging statements within mod_negotiation. [Koen Holtman]
3307 *) Fixed a rare memory corruption possibility in mod_dir if the index
3308 file is negotiable and no acceptable variant can be found.
3309 [Dean Gaudet, Roy Fielding, Martin Kraemer]
3311 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
3312 searching the Win32 registry for script interpreters.
3315 *) Win32: The compiled-in default filename for the error log is now
3316 error.log, which matches the default in the distributed httpd.conf.
3319 *) Win32: Any error messages from -i or -u command line options are now
3320 displayed on the console output rather than sent to the error log.
3321 Also the "Running Apache..." message is not output unless Apache is
3322 going to serve requests. [Paul Sutton]
3324 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
3325 and use a private significator ('$apr1$') to mark passwords as
3326 being smashed with our own algorithm. Also abstract the password
3327 checking into a new ap_validate_password() routine. [Ken Coar]
3329 *) Win32: The filename validity checker now allows "COM" but refuses
3330 access to "COM1" through "COM4". This allows filenames such
3331 as "com.name" to be served. [Paul Sutton] PR#3769.
3333 *) BS2000: Adapt to the new ufork() system call interface which will
3334 make subtasking easier on the OSD/POSIX mainframe environment.
3337 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
3338 ap_compat.h. [David White <david@persimmon.com>] PR#3725
3340 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
3341 use `.db' instead of `.pag' not only for FreeBSD, but also when
3342 the NDBM library looks like Berkeley-DB based.
3343 [Ralf S. Engelschall] PR#3773
3345 *) Add ability to handle DES or MD5 authentication passwords.
3346 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
3348 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
3350 *) SECURITY: Avoid some buffer overflow problems when escaping
3351 quoted strings. (This overflow was on the heap and we believe
3352 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
3354 *) Let src/Configure be aware of CFLAGS options starting with plus
3355 signs as it's the case for the HP/UX compiler.
3356 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
3358 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
3359 and check to see if the tar we wind up with supports '-h'.
3360 [Jim Jagielski] PR#3671
3362 *) A consistent and conservative style for all shell scripts has been
3363 implemented. Basically, all shell string tests use the traditional
3364 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
3365 to protect against bare null variable strings (ie: wrapping both
3366 sides with double quotes and prepending 'x'). 'x' was chosen
3367 because it's more universal and hopefully easier for old shell
3368 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
3371 *) The status module now prints out both the main server generation as
3372 well as the generation of each process. Also, the vhost info is
3373 printed with '?notable'. [Jim Jagielski]
3375 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
3376 and this makes its functions available to things in src/support.
3379 Changes with Apache 1.3.4
3381 *) Renamed macros status_drops_connection to ap_status_drops_connection
3382 and vestigial scan_script_header to ap_scan_script_header_err,
3383 mostly for aesthetic reasons. [Roy Fielding]
3385 *) The query switch "httpd -S" didn't exit after showing the
3386 vhost settings. That was inconsistent with the other query functions.
3389 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
3390 filename to the end of the STANDARD_MODULE_STUFF. Its
3391 presence at the beginning prevented reporting of the filename
3392 for modules compiled before 1 January 1999. [Ken Coar]
3394 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
3395 to detect and prevent access to special DOS device file names.
3396 [Paul Sutton, Ken Parzygnat]
3398 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
3399 and Makefile_win32_debug.txt (debug build) that work on Win95.
3400 Run each of the following from the src directory:
3401 nmake /f Makefile_win32.txt # compiles normal build
3402 nmake /f Makefile_win32.txt install # compiles and installs
3403 nmake /f Makefile_win32.txt clean # removes compiled junk
3404 nmake /f Makefile_win32_debug.txt # compiles debug build
3405 nmake /f Makefile_win32_debug.txt install
3406 nmake /f Makefile_win32_debug.txt clean
3409 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
3410 to build binary distributions. [Lars Eilebrecht]
3412 *) IndexOptions SuppressColumnSorting only turned off making
3413 the column headers anchors; you could still change the display
3414 order by manually adding a '?N=A' or similar query string to the
3415 URL. Now SuppressColumnSorting locks in the sort order so
3416 it can't be overridden this way. [Ken Coar]
3418 *) Added IndexOrderDefault directive to supply a default sort order
3419 for FancyIndexed directory listings. [Ken Coar] PR#1699
3421 *) Change the ap_assert macro to a variant that works on all platforms.
3422 [Richard Prinz <richard.prinz@cso.net>] PR#2575
3424 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
3425 search for an underscore on dlsym() (as it's already the case
3426 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
3428 *) Small fix for mod_env.html: The module was documented as to be _not_
3429 compiled into Apache per default, although it _IS_ compiled into
3430 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
3432 *) Instead of fixing a bug in the generation procedure for config.status (a
3433 backslash was missing) we remove the bug together with it's complete
3434 context because the special cases of the past can now no longer occur
3435 because of the recent magic for the --with-layout default.
3436 [Ralf S. Engelschall] PR#3590
3438 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
3439 making sure the src/support/ tools are _forced_ to be build last (they
3440 depend on other libraries).
3441 [Markus Theissinger <markus.theissinger@gmx.de>]
3443 *) Fix installation procedure: Now that os-inline.c is actually used (a
3444 recently fixed bug prevented this) we need to also install os-include.c
3445 in addition to os.h into the PREFIX/include/ location or building of
3446 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
3448 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
3449 allow us to distinguish between a garbled DSO (or even a file which isn't
3450 an Apache module DSO at all) and a DSO which doesn't match the current
3451 Apache API. [Ralf S. Engelschall] PR#3152
3453 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
3454 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
3455 match case insensitive (this especially avoids nasty patterns like
3456 `[tT][eE][sS][tT]'). Second two additional internal map functions
3457 `escape' and `unescape' were added which can be used to escape/unescape
3458 to/from hex-encodings in URLs parts (this is especially useful in
3459 combination with map lookups).
3460 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
3462 *) Renamed the macro escape_uri() to ap_escape_uri() which was
3463 forgotten (because it was a macro) in the symbol renaming process.
3464 [Ralf S. Engelschall]
3466 *) Fix some inconsistencies related to the scopes of directives. The only
3467 user visible change is that the directives `UseCanonicalName' and
3468 `ContentDigest' now use the (more correct) `Options' scope instead of
3469 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
3471 *) Using DSO, the Server token was being mangled. Specifically, the
3472 module's token was being added first before the Apache token. This
3473 has been fixed. [Jim Jagielski]
3475 *) Major overhaul of mod_negotiation.c, part 2.
3476 - properly handle "identity" within Accept-Encoding.
3477 - allow encoded variants in RVSA negotiation and let them appear in
3478 the Alternates field using the non-standard "encoding" tag-list.
3479 - fixed both negotiation algorithms so that an explicitly accepted
3480 encoding is preferred over no encoding if "identity" is not
3481 included within Accept-Encoding.
3482 - added ap_array_pstrcat() to alloc.c for efficient concatenation
3483 of large substring sequences.
3484 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
3487 *) Major overhaul of mod_negotiation.c, part 1.
3488 - cleanups to mod_negotiation comments and code structure
3489 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
3490 support for everything in the upcoming HTTP/1.1
3491 revision (draft-ietf-http-v11-spec-rev-06.txt).
3492 - language tag matching also handles tags with more than 2
3494 - empty Accept, Accept-Language, Accept-Charset headers are
3495 processed correctly; previously an empty header would make all
3496 values acceptable instead of unacceptable.
3497 - allowed for q values in Accept-Encoding
3498 - added support for transparent content negotiation (rfc2295 and
3499 rfc2296) (though we do not implement all features in these drafts,
3500 e.g. no feature negotiation). Removed old experimental version.
3501 - implemented 'structured entity tags' for better cache correctness
3502 (structured entity tags ensure that caches which can deal with Vary
3503 will (eventually) be updated if the set of variants on the server
3505 - this involved adding a vlist_validator element to request_rec
3506 - this involved adding the ap_make_etag() function to the global API
3507 - modified guessing of charsets used by Apache negotiation algorithm
3508 to guess 'no charset' if the variant is not a text/* type
3509 - added code to sort multiviews variants into a canonical order so that
3510 negotiation results are consistent across backup/restores and mirrors
3511 - removed possibility of a type map file resolving to another type map
3512 file as its best variant
3513 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
3515 *) RFC2396 allows the syntax http://host:/path (with no port number)
3516 but the proxy disallowed it (ap_proxy_canon_netloc()).
3517 [David Kristol <dmk@bell-labs.com>] PR#3530
3519 *) When modules update/modify the file name in the configfile_t structure,
3520 syntax errors will report the updated name, not the original one.
3521 [Fabien Coelho <coelho@cri.ensmp.fr>] PR#3573
3523 *) Correct some filename case assumptions from WIN32 to
3524 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]
3526 *) For %v log ServerName regardless of the UseCanonicalName
3527 setting (similarly for %p). [Dean Gaudet]
3529 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
3530 rather late (too late for some invocations of TestCompile).
3531 This improves the make environment available to TestCompile and
3532 the *.module scripts. [Martin Kraemer]
3534 *) The hashbang emulation code in ap_execve.c would interpret
3535 #!/hashbang/scripts correctly, but failed to fall back to a
3536 standard shell for scripts which did NOT start with #!
3537 Now SHELL_PATH is started in these cases. [Martin Kraemer]
3539 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
3542 *) Update APXS manual page: some -q option arguments were missing
3543 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
3545 *) Cleanup the command line options: `-?' was documented to show
3546 the usage list but does it with an error because `?' is not a valid
3547 command. OTOH a lot of users expect `-h' to print such a usage list and
3548 instead are annoyed for ages by our huge unreadable list of directives.
3549 So we now changed the command line options this way:
3551 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
3552 very similar to the popular linker option.
3554 Intent: while -l gives the small list of modules, -L now gives the
3555 large list of directives implemented by these modules. This is also
3556 consistent with -v (short version info) and -V (large version info).
3558 Intent: it's now the expected option ;-)
3559 The manual page was adjusted accordingly.
3560 [Ralf S. Engelschall] PR#2714
3562 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
3563 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
3565 *) Removed recently introduced bugs and disfigurements in APACI:
3566 o fixed argument line processing: using $args was broken: It was not
3567 initialized and using args="$args $apc_option" and even args="$args
3568 \"$apc_option\"" fails in the second processing round for any arguments
3569 containing whitespaces. The only correct way is to use the construct
3570 "$@" (but not possible here) or iterate _both_ times over the implicit
3571 argument line (no argument to for-loop) which is what we now use.
3572 o make --with-layout=Apache the default without creating
3573 redundancy (copying the --with-layout block in the argument parsing
3574 loop). We achieve this by using the "$@" construct together with the
3575 `set' command to prepend --with-layout=Apache to the command line in
3576 case --with-layout is not used.
3577 o fixed auto-suffix handling now that config.layout exists.
3578 Paths which are auto-suffixed are marked with a trailing plus sign in
3579 config.layout and every path now can be marked this way (not only the
3580 four paths for which we do it currently). Additionally the suffix is
3581 no longer a static one. Instead it's now `/<target>' where <target> is
3582 the argument of the --target option or per default `httpd'.
3583 o allow also tabs (and only spaces) where we match whitespaces
3584 o various fixes and cleanups related to used shell coding style
3585 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
3586 o trimmed output of --help to fit into 80 columns
3587 [Ralf S. Engelschall]
3589 *) Added two new core API functions, ap_single_module_configure() and
3590 ap_single_module_init(), which are now used by mod_so to configure a module
3591 after loading. [Ralf S. Engelschall]
3593 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
3594 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
3595 of ap_config.h to allow serialized accept for multiport listens.
3596 [Roy Fielding, Curt Sampson] PR#3120
3598 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
3599 of ap_config.h that would skip several defines if DEFAULT_GROUP
3600 was overridden. [Roy Fielding]
3602 *) PORT: The I86 version of DGUX has support for strncasecmp and
3603 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
3605 *) Fix ordering of definitions in ap_config.h so that ap_inline is
3606 defined before it might be used. [Victor Khimenko]
3608 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
3609 [Tom Serkowski <tks@bsdi.com>] PR#3453
3611 *) Make generation of src/Configuration.apaci more robust: It failed to
3612 differenciate between modules when one module name was a postfix of
3613 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
3614 just XXX (think about totally non-standard names like "apache_ssl", too).
3615 [Ralf S. Engelschall] PR#3380
3617 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
3618 since 1.3b7) and make whitespace handling more robust (it failed horrible
3619 when whitespaces were present in the arguments of -D options).
3620 [Ralf S. Engelschall] PR#3240
3622 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
3623 creates an external package shadow tree in DIR before the local build
3624 shadow tree is generated under DIR. This way one can have the extracted
3625 Apache distribution tree read-only on NFS or CDROM and still build Apache
3626 from these sources. An automatically triggered VPATH-like mechanism is
3627 provided through the TOP variable, too.
3628 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez@apple.com>]
3630 *) Fix negotiation so that a Vary response header is correctly
3631 generated when, for a particular dimension, variants only vary
3632 in having or not having a value for that dimension. [Paul Sutton]
3634 *) Fix negotiation so that we prefer an encoded variant over an
3635 unencoded variant if the user-agent explicitly says it can
3636 accept that encoding. Previously we always preferred the unencoded
3638 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
3640 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
3641 and the usage page was inconsistent with the functionality and manpage.
3642 [Ralf S. Engelschall]
3644 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
3645 They can occur multiple times and their arguments (`xxx') are passed AS
3646 IS to the compiler/linker command. [Ralf S. Engelschall]
3648 *) Fixed possible (but harmless in practice) bug in the DBM lookup
3649 procedure of mod_rewrite: very long keys were truncated.
3650 [Ralf S. Engelschall]
3652 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
3653 identifier, currently "Apache" and "GNU" are pre-defined in the file
3654 config.layout. Custom layouts are possible by using FILE:ID as the
3655 argument where the layout ID is taken from FILE.
3657 The config.layout file consists of <Layout ID>..</Layout> sections
3658 where inside those sections "path_variable: path_value" pairs can be
3659 specified. These lines are converted to path_variable='path_value'.
3661 *) Add a DefaultLanguage directive so that files missing a language
3662 extension (e.g., .fr, .de) can be labelled as being some other
3663 default language. DefaultLanguage can appear in <Directory> and
3664 <Files> containers as well as .htaccess files. [Paul Sutton]
3667 *) Fix TARGET configuration when configuring and installing using
3668 APACI configure. TARGET now defines the basename of the configuration
3669 file, startup script, manual page, etc. log_error_core() now reports
3670 the server binary name given by argv[0]. TARGET can now also be defined
3671 with --target=TARGET parameter passed to APACI configure.
3672 [Ralf Engelschall, Randy Terbush]
3674 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
3675 rather than OPT_INCLUDES [Rainer Schoepf <schoepf@uni-mainz.de>]
3677 *) ap_md5_binary() was using sprintf() rather than a table lookup
3678 to convert binary bytes to hex digits.

3684 *) API: ap_exists_config_define() function is now "public" [Doug MacEachern]
3686 *) Fix documentation of `Action' directive: It can activate a CGI script
3687 when either a handler or a MIME content type is triggered by the request.
3688 [Andrew Pimlott <pimlott@math.harvard.edu>] PR#3340
3690 *) Document the `add' command of `dbmmanage' in `dbmmanage.1' manpage.

3693 *) Ignore a "ErrorDocument 401" directive with a full URL and write a
3694 notice to the error log. It is not possible to send a 401 response
3695 and a redirect at the same time. [Lars Eilebrecht]
3697 *) Fallback to native compilers for IRIX-32 platform. It seems that
3698 a gcc 2.8.1 compiled apache is logging client addresses with all
3699 bits set (255.255.255.255). This is the second such problem caused
3700 by gcc 2.8.1 compiler. The first being broken semaphore locking.
3703 *) Updated mime.types to reflect current Internet media types
3704 and include a URL to the registry.
3705 [Manoj Kasichainula, Roy Fielding] PR#2380, 2286, 2246
3707 *) SECURITY: Do a more complete check in mod_include to avoid
3708 an infinite loop of recursive SSI includes. [Marc Slemko] PR#3323
3710 *) Add APACI --suexec-docroot and --suexec-logfile options which can be
3711 used to set the document root directory (DOC_ROOT) and the suexec
3712 logfile (LOG_EXEC), respectively. Additionally the --layout option
3713 was changed to show more information about the suEXEC setup.
3714 [Lars Eilebrecht] PR#3316, 3357, 3361
3716 *) Added the last two WebDAV status codes of 424 (Failed Dependency)
3717 and 507 (Insufficient Storage) for use by third-party modules.
3720 *) Enabled all of the WebDAV method names for use by third-party
3721 modules, Limit, and Script directives. That includes PATCH,
3722 PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.
3723 Improved mod_actions.c so that it can use any of the methods
3724 defined in httpd.h. Added ap_method_number_of(method) for
3725 getting the internal method number. [Roy Fielding]

3748 the interpreter and the Win32 error code returned. [Marc Slemko]
3750 *) Disable sending of error-notes on a 500 (Internal Server Error) response
3751 since it often includes file path info. Enable sending of error-notes
3752 on a 501 (Method Not Implemented). [Roy Fielding] PR#3173
3754 *) http_config.c would respond with 501 (Method Not Implemented) if a
3755 content type handler was specified but could not be found, which
3756 should have been a 500 response. Likewise, mod_proxy.c would responsd
3757 with a 501 if the URI scheme is unrecognized instead of the correct
3758 response of 403 (Forbidden). [Roy Fielding]
3760 *) SECURITY: Eliminate DoS attack when a bad URI path contains what
3761 looks like a printf format escape. [Marc Slemko, Studenten Net Twente]
3763 *) Fix in mod_autoindex: for files where the last modified time stamp was
3764 unavailable, an empty string was printed which was 2 bytes short.
3765 The size and description columns were therefore not aligned correctly.

3772 *) Add the actual server_rec structure of the specific Vhost to the
3773 scoreboard file and avoid a string copy (as well as allow some
3774 further future enhancements). [Harrie Hazewinkel
3775 <harrie.hazewinkel@jrc.it>]
3777 *) Add APACI --permute-module=foo:bar option which can be used to
3778 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
3779 in the Configuration[.apaci] file. Two special and important variants are
3780 supported for the option argument: first BEGIN:foo which permutes module
3781 mod_foo with the begin of the module list, i.e. it `moves' the module to
3782 the begin of the list (gives it lowest priority). And second foo:END
3783 which permutes mod_foo with the end of the module list, i.e. it `moves'
3784 the module to the end of the list (gives it highest priority).

3787 *) Fix problem with 'apache -k shutdown' and startup event
3788 synchronisation (Win32). [Ken Parzygnat <kparz@raleigh.ibm.com>]
3791 *) The config parser wasn't correctly noticing a missing '>'
3792 on container start lines (e.g., it wouldn't spot
3793 "<Directory /" as a syntax error). [Ryan Bloom <rbbloom@us.ibm.com>]
3796 *) Add a 'RemoveHandler' directive which will selectively remove
3797 all handler associations for the specified file extensions.

3800 *) Properly handle & allow "nul" and ".*/null" in AccessConfig and

3823 *) PORT: DSO/ELF support for FreeBSD 3.0.
3824 [Ralf S. Engelschall, Dirk Froemberg <ibex@physik.TU-Berlin.DE>]
3826 *) Add a "default-handler" handler that calls the default_hander()
3827 function which is normally called for static content. This allows
3828 you to override a specific handler. [Marc Slemko]
3830 *) Further simplify checking for absolute paths by replacing an
3831 hard-coded syntax check with a call to a routine we already created to
3832 do this. [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2976, 3074
3834 *) Log an error if we encounter a malformed "require" directive
3835 in mod_auth if we know that we know that no other module can
3836 deal with it. [Marc Slemko]
3838 *) Remove ap_private_extern method of hiding conflicting symbols
3839 on the NEXT platform because it is not correct for all versions,
3840 and the versions for which it is correct are unknown.

3847 is encountered in an .htaccess file somewhere down the tree.
3850 *) Minor performance improvement to ap_escape_html(). [Roy Fielding]
3852 *) Fixed a segmentation violation in mod_proxy when a response is
3853 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
3855 Changes with Apache 1.3.3
3857 *) Added a complete implementation of the Expect header field as
3858 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
3859 response when we already know the final status, which is mighty
3860 useful for PUT responses that result in 302 or 401. [Roy Fielding]
3862 *) Remove extra trailing whitespace from the getline results as part
3863 of the protocol processing, which is extra nice because it works
3864 between continuation lines, is almost no cost in the normal case
3865 of no extra whitespace, and saves memory. [Roy Fielding]
3867 *) Added new HTTP status codes and default response bodies from the
3868 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
3869 HTTP Extension Framework (510) specifications. Did not add the
3870 WebDAV 424 and 425 codes because they are bogus. We don't use any
3871 of these codes yet, but they are now available to 3rd-party modules.

3976 who were the top_module. [Doug MacEachern]
3978 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
3979 mod_auth_db to both be friendly to users who wants to use this version
3980 and to avoid problems under platforms where only version 2.x is present.

3983 *) When using ap_log_rerror(), make the error message available to the
3984 *ERROR_NOTES envariables by default. [Ken Coar]
3986 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
3987 You now must define a BS2000Account name for the server User.
3988 This has fewer security implications than the old approach.
3991 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
3992 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
3993 platform to make the braindead HPUX linker happy. Notice, for the module
3994 DSOs we don't have to use this, because these are loaded manually (and
3995 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
3997 *) Remove 64 thread limit on Win32.

4004 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
4006 *) Make PrintPath work generically instead of having one version
4007 strictly for OS/2. [Jim Jagielski, Brian Havard]
4009 *) Fix the recently introduced C header file checking: We now use the C
4010 pre-processor pass only (and no longer the complete compiler pass) to
4011 determine whether a C header file exists or not. Because only this way
4012 we're safe against inter-header dependencies (which caused horrible
4013 portability problems). The only drawback is that we now have a CPP
4014 configuration variable which has to be determined first (we do a similar
4015 approach as GNU Autoconf does here). When all fails the user still has
4016 the possibility to override it manually via APACI or src/Configuration.
4017 As a fallback for the header check itself we can directly check the
4018 existance of the file under /usr/include, too.
4019 [Ralf S. Engelschall] PR#2777
4021 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined

4049 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
4050 platform, because it's only supported under version 4.0 and higher. But
4051 because our GuessOS is still unaware of Digital UNIX versions and the
4052 -msym is just to optimize the DSO statup time a little bit it's safe and
4053 best when we leave it out now. [Ralf S. Engelschall] PR#2969
4055 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
4056 functions: First all three functions no longer fail on strings containing
4057 "%" chars and second ap_log_printf() no longer does a double-formatting
4058 (instead it directly passes through the message to be formatted to the
4059 real internal formatting function). [Ralf S. Engelschall] PR#2941
4061 *) Allow "Include" directives anywhere in the server config
4062 files (but not .htaccess files). [Ken Coar] PR#2727
4064 *) The proxy was refusing to serve CONNECT requests except to
4065 port 443 (https://) and 563 (snews://). The new AllowCONNECT
4066 directive allows the configuration of the ports to which a
4067 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
4069 *) mod_expires will now act on content that is not sent from a file
4070 on disk. Previously it would never add an Expires: header to
4071 any response that did not come from a file on disk; the only
4072 case where it still doesn't (and can't) add one for that type of
4073 content is if you are using a modification date based setting.
4074 [Marc Slemko, Paul Phillips <paulp@go2net.com>]
4076 *) Problems encountered during .htaccess parsing or CGI execution
4077 that lead to a "500 Server Error" condition now provide explanatory
4078 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
4081 *) Add NameWidth keyword to IndexOptions directive so that the
4082 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
4085 *) Recognize lowercase _and_ uppercase `uname' results under
4086 SCO OpenServer. [David Coelho <drc@ppt.com>]
4088 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
4089 a common problem of (mis-administrated?) IIS servers, make the apache
4090 proxy immune to these errors (and ignore the duplicates, but log
4091 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
4093 *) The <IfModule and <IfDefine block starting directives now only
4094 allow exactly one argument. Previously, the optional negation
4095 character '!' could be separated by whitespace without a syntax
4096 error being reported, albeit defeating the IfModule functionality
4097 (enclosed directives would ALWAYS be executed). By using the
4098 stricter syntax, these hard-to-track errors can be avoided.
4101 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
4102 cause the standalone FancyIndexing directive to logically OR
4103 into any existing IndexOptions settings rather than wiping
4104 them out. [Ken Coar]
4106 *) Changes in ftp proxy: make URL parsing simpler by using the
4108 + Add display of the "current directory" in cases where it's
4109 different from the supplied path (e.g., ftp://user@host/ lives
4110 in /home/user, not in /, therefore clicking on "../" in the
4111 starting directory might send us to /home/).
4112 + When ftp login fails, (esp. when a user name was part of the
4113 URL already), we now return [401 Unauthorized ] to allow the
4114 browser to pop up an authorization dialog. This makes passwords
4115 slightly less visible (they don't appear in the regular log files)
4116 and implements a functionality that other www proxy servers
4120 *) Triggered by the recent "Via:" header changes, the proxy module would
4121 dump core for replies with invalid headers (e.g., duplicate
4122 "HTTP/1.0 200 OK" lines). These errors are now logged and the
4123 core dump is avoided. Also, broken replies are not cached.
4124 [Martin Kraemer] PR#2914
4126 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
4127 plop gmon.out profile data for each child [Doug MacEachern]
4129 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
4130 config.status script to be immune against arguments with whitespaces.
4131 [Yves Arrouye <yves@apple.com>] PR#2866
4133 *) Replace the inlined information grabbing stuff for the configuration
4134 adjustment feature (no --without-confadjust) with calls to a new helper
4135 script `buildinfo.sh' which is both more flexible and already proofed to
4136 be more robust against platform differences. This mainly fixes the
4137 recently occured ``sed: command garbled: ...'' problems.
4138 [Ralf S. Engelschall] PR#2776, PR#2848
4140 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
4141 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
4142 without complains after we recently added the POST feature.
4143 [Ralf S. Engelschall]
4145 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
4146 modules as API functions and we forgot them at the big symbol renaming.
4147 [Ralf S. Engelschall]
4149 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html

4155 *) Add the ability to do POST requests to the ab benchmarking tool.
4156 [Kurt Sussman <kls@best.com>] PR#2871
4158 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
4159 5 to 10 because there are some users out there who always have 5 to 8
4160 variables in one RewriteRule and had to patch mod_rewrite.h for every
4161 release. So 15 should be now more than enough, even for them. (I never
4162 needed more than 4 in my RewriteRules ;-)
4163 [Ralf S. Engelschall]
4165 *) Make the proxy generate and understand Via: headers
4168 *) Change the proxy to use tables instead of array_headers for
4169 the header lines. [Martin Kraemer]
4171 *) Make sure the config.status file is not overridden when just
4172 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
4174 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
4175 provide a way to trace API changes that add functionality but do
4176 not create a compatibility issue for precompiled modules, etc.
4177 See include/ap_mmn.h for more details. [Randy Terbush]
4179 *) Fix suexec installation under `make install root=xxx' situation.
4180 [Ralf S. Engelschall]
4182 *) Extend the output of the -V switch to include the paths of all
4183 compiled-in configuration files, if they were overridden at
4184 compile time, for least astonishment of the user.
4187 *) When READing a request in ExtendedStatus mode, the "old"
4188 vhost, request and client information is not displayed.
4191 *) STATUS is no longer available. Full status information now
4192 run-time configurable using the ExtendedStatus directive.
4195 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
4196 cpu time attacks) in header parsing. Add ap_overlap_tables(),
4197 a function which can be used to perform bulk update operations
4198 on tables in a more efficient manner. [Dean Gaudet]
4200 *) SECURITY: Added compile-time and configurable limits for
4201 various aspects of reading a client request to avoid some simple
4202 denial of service attacks, including limits on maximum request-line
4203 size (LimitRequestLine), number of header fields (LimitRequestFields),
4204 and size of any one header field (LimitRequestFieldsize). Also added
4205 a configurable directive LimitRequestBody for limiting the size of the
4206 request message body. [Roy Fielding]
4208 *) Make status module aware of DNS and logging states, even if
4209 STATUS not defined. [Jim Jagielski]
4211 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
4213 *) Enhance mod_speling so that CheckSpelling can be used in
4214 <Directory> containers and .htaccess files. [Ken Coar]
4216 *) API: new ap_custom_response() function for hooking into the
4217 ErrorDocument mechanism at runtime [Doug MacEachern]
4219 *) API: new ap_uuencode() function [Doug MacEachern]
4221 *) API: scan_script_header_err_core() now "public" and renamed
4222 ap_scan_script_header_err_core() [Doug MacEachern]
4224 *) The 'status' module will now show the process pid's and their
4225 state even without full STATUS accounting. [Jim Jagielski]
4227 *) Restore the client IP address to the error log messages, this
4228 was lost during the transition from 1.2 to 1.3. Add a new
4229 function ap_log_rerror() which takes a request_rec * and
4230 formats it appropriately. [Dean Gaudet] PR#2661
4232 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
4233 whitespace in input lines -- including within quoted strings.
4235 but leading and trailing whitespace should continue to be
4236 stripped [Martin Kraemer]
4238 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
4239 the ugly use of an env. variable and use command-line args for
4240 alternate $PATH. Make more like advanced 'type's as well.
4243 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
4244 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
4245 <alain.st-denis@ec.gc.ca>] PR#2736
4247 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
4249 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
4250 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
4251 directory was renamed to src/os/os2/ for consistency.
4252 [Brian Havard, Ralf S. Engelschall]
4254 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
4255 files (here modules) against other DSO files (here shared libraries).
4256 This is done by determining a subset of LIBS which can be safely used for
4257 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
4258 disabled for all platforms to avoid problems with this (experimental)
4259 rule. But we provide it now for those people how ran into problems and
4260 want to came out by forcing linking against DSOs.
4261 [Ralf S. Engelschall] PR#2587
4263 *) Fix suEXEC start message: Has to be of `notice' level to really get

4277 cause the client to miss the HTTP error response. [Roy Fielding]
4279 *) One more portability fix for APACI shadow tree support: Swap order of awk
4280 and sed in top-level configure script to avoid sed fails on some
4281 platforms (for instance SunOS 4.1.3 and NCR SysV) because of the

4377 *) Add new flags for ap_unparse_uri_components() to make it generate
4378 the scheme://sitepart string only, or to omit the query string.
4381 *) WIN32: Canonicalize ServerRoot before checking to see if it
4382 is a valid directory. The failure to do this caused certain
4383 ServerRoot settings (eg. "ServerRoot /apache") to be improperly
4384 rejected. [Marc Slemko]
4386 *) Global renaming of C header files to both get rid of conflicts with third
4387 party packages and to again reach consistency:
4388 1. conf.h -> ap_config.h
4389 2. conf_auto.h -> ap_config_auto.h \ these are now merged

4393 Backward compatibility files for conf.h and compat.h were created.
4395 *) mod_mmap_static will no longer take action on requests unless at
4396 least one "mmapfile" directive is present in the configuration.
4397 This experimental module has to do some black magic to operate
4398 inside the current API and thus creates side-effects for other
4399 modules under some circumstances.

4512 *) WIN32: If we can't figure out how to execute a file in a script
4513 directory, bail out of the request with an error message. [W G Stoddard]
4515 *) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
4516 these are treated by Win32 as if they are ".." but are not detected by
4517 other machinery within Apache. This is something of a kludge but
4518 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
4520 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
4521 pools and thus pollutes libap (until the pool stuff is moved there).

4538 user. Package authors can use the --without-confadjust option to disable
4539 these configuration adjustments.

4543 to add an extra Makefile dependency for the httpd target, for instance
4544 to external third-party libraries, etc.

4547 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
4548 as <IfModule>..</IfModule> sections) which can be used to skip or process
4549 contained commands dependend of ``-D PARAMETER'' options on the command
4550 line. This can be used to achieve logical conditions like <IfDefine
4551 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)

4553 modules via LoadModule, etc. [Ralf S. Engelschall]

4560 truncated which forced following HTTP headers to be data in the HTTP
4561 reponse. [Ralf S. Engelschall, Charles Fu <ccwf@bacchus.com>]
4564 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
4565 in top-level configure script to avoid sed fails on some platforms (for
4566 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
4567 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
4569 *) Improve performance of directory listings (mod_autoindex) by comparing
4570 integer keys (last-modified and size) as integers rather than converting
4571 them to strings first. Also use a set of explicit byte tests rather
4572 than strcmp() to check for parent directory-ness of an entry. Oh, and
4573 make sure the parent directory (if displayed) is *always* listed first
4574 regardless of the sort key. Overall performance winnage should be good
4575 in CPU time, instruction cache, and memory usage, particularly for large
4576 directories. [Ken Coar]
4578 *) Add a tiny but useful goody to APACI's configure script: The generation
4579 of a config.status script (as GNU Autoconf does) which remembers the used
4580 configure command and hence can be used to restore the configuration by
4581 just re-running this script or for remembering the configuration between
4583 [Ralf S. Engelschall]
4585 *) Add httpd -t (test) option for running configuration syntax tests only.
4586 If something is broken it complains and exits with a return code
4587 non-equal to 0. This can be used manually by the user to check the Apache
4588 configuration after editing and is also automatically used by apachectl
4589 on (graceful) restart command to make sure Apache doesn't die on restarts
4590 because of a configuration which is now broken since the last (re)start.
4591 This way `apachectl restart' can be used inside cronjobs without having
4592 to expect Apache to be falling down. Additionally the httpd -t can be run
4593 via `apachectl configtest'.

4743 generated Makefile more user friendly. [Ralf S. Engelschall]
4745 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
4746 was updated to use the normal apache error processing, thereby allowing
4747 proxy errors to be treated by ErrorDocument's as well. For this
4748 purpose, a new module-to-core communication variable "error-notes"
4749 was introduced; the proxy (and possibly other modules) communicates
4750 its error text using this variable. Its content is copied to a new
4751 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
4752 The old proxy special error routine ap_proxy_log_uerror()

4833 *) The Makefiles assumed that DSO files are build via $(LD). This
4834 is broken for two reasons: First we never defined at least LD=ld
4835 somewhere to make sure this works (it was silently assumed that most Make
4836 provide a built-in LD definition - ARGL!) and second using the generic LD
4837 variable is not the truth. Instead a special variable named LD_SHLIB is
4838 reasonable because although "ld" is usually the default, the command for
4839 building DSO files can be "libtool" or even "cc" on some systems.

4860 any Makefile but make sure that at least the "-K inline" is kept in

4863 - updated the dependencies theirself
4864 - removed not existing SHLIB variable from "clean" targets
4865 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
4866 already exists and OBJS_PIC are also just plain objects and have not
4867 directly to do with "shared" things. The only difference is that they
4868 contain PIC. So OBJS_PIC is the more canonical name.
4869 - Updated the Makefile-dependency lines for OBJS_PIC
4870 - Removed the Makefile-dependency line in Configure to avoid double
4872 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
4873 of xxx.lo as GNU libtool does with its PIC objects
4874 - reduce local complexity in modules Makefile.tmpl by moving the last
4875 existing target "depend" to the generation section in Configure, too.
4876 - removed the historical $(SPACER) which was used in the past together
4877 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
4878 is no longer needed.
4879 - force the build and run of the gen_xxx programs under main/ as the
4880 first step before building the objects because it looks cleaner

4883 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
4886 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
4889 *) WIN32: Don't force ISAPI headers to finish with \n.
4890 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
4892 *) When opening "configuration" files (like httpd.conf, htaccess
4893 and htpasswd), Apache will not allow them to be non-/dev/null
4894 device files. This closes a DoS hole. At the same time,
4895 we use ap_pfopen to open these files to handle timeouts.
4896 [Jim Jagielski, Martin Kraemer]
4898 *) Apache will now log the reason its httpd children exit if they exit
4899 due to an unexpected signal. (It requires a new porting define,
4900 SYS_SIGLIST, which if defined should point to a list of text
4901 descriptions of the signals available. See PORTING.) [Dean Gaudet]
4903 *) WIN32: chdir() doesn't make sense in a multithreaded environment
4904 like WIN32. Before, Win32 CGI's could have had sporadic failures
4905 if a chdir call from one thread was made between another chdir call
4906 and a spawn in another thread. So, for now don't chdir for CGI scripts
4907 in WIN32. The current CGI "spec" is unclear as to whether it's
4908 necessary. Long-term fix is to either serialize the chdir/spawn combo
4909 or use WIN32 native calls to spawn a process. This temp fix was
4910 necessary to remove this as a showstopper for 1.3's release.
4913 *) Cleanup the suEXEC support in APACI and make it more safe:
4914 1. Add big fat hint in INSTALL about risks and to read the
4915 htdocs/manual/suexec.html document before using the suexec-related
4917 2. Make sure the user has at least provided one --suexec-xxxx option
4918 (specifies suEXEC parameters) in addition to --enable-suexec option.
4919 If only --enable-suexec is given APACI stops with a hint to INSTALL
4920 and htdocs/manual/suexec.html documents.
4921 3. Provide two additional --suexec-xxxx options to make the suEXEC
4922 configuration complete (especially for package maintainers who else
4923 had to patch the source tree) by providing ways to configure minimal
4924 UID/GID and safe PATH, too.
4925 [Ralf S. Engelschall]
4927 *) Cleanup of the `configure --shadow' process:
4928 - make sure the configure script creates its temporary files in the
4929 shadow tree to avoid conflicts with parallel configure runs
4930 - removed unnecessary option "-r" from "rm" call for Makefiles
4931 - make sure the configure scripts creates the shadow-wrapper Makefile
4932 only when no shadow trees already exists
4933 - make sure "make distclean" removes the shadow-wrapper Makefile but only
4934 when no more shadow trees exists
4935 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
4936 as fast (in the past it needed 70sec, now it runs just 38sec)
4937 - make sure CVS does not complain about the created files
4938 Makefille.<gnutriple> and directories src.<gnutriple>
4939 [Ralf S. Engelschall]
4941 *) Added the ap_add_version_component() API routine and the
4942 AddVersionPlatform core directive. The first allows modules to
4943 declare themselves in the Server response header field value,
4944 augmenting the SERVER_SUBVERSION define in the Configuration file
4945 with run-time settings (more useful in a loadable-module environment).
4946 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
4947 into the server version string. [Ken Coar] PR#2056
4949 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
4952 *) Emit the "Accept-Range" header for the default handler.
4953 [Brian Behlendorf] PR#1464
4955 *) Add a note to httpd.conf-dist that apache will on some systems fail
4956 to start when the Group # is set to a negative or large positive value.
4959 *) Make sure the module execution order is correct even when some modules
4960 are loaded under runtime (`LoadModule') via the DSO mechanism:
4961 1. The list of loaded modules is now a dynamically allocated one
4962 and not the original statically list from modules.c
4963 2. The loaded modules are now correctly setup by LoadModule for
4964 later use by the AddModule command.
4965 3. When the DSO mechanism for modules is used APACI's `install'
4966 target now enables all created `LoadModule' lines per default because
4967 this is both already expected by the user _and_ needed to avoid
4968 confusion with the next point and reduces the Makefile.tmpl complexity
4969 4. When the DSO mechanism for modules is used, APACI's `install'
4970 target now additionally makes sure the module list is reconstructed
4971 via a complete `ClearModuleList+AddModule...' entry.
4972 5. The support tool `apxs' now also makes sure an AddModule command
4973 is added in addition to the LoadModule command.
4974 6. The modules.c generation was extended to now contain two
4975 comments to make sure no one is confused by the confusing terminology
4976 of loading/linking (we use load=link+load & link=activate instead of
4977 the obvious load=activate & link=link :-( )
4978 This way now there is no longer a difference under execution time between
4979 statically and dynamically linked modules.

4982 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
4983 Big Symbol Renaming. [Ralf S. Engelschall]
4985 *) Add a comment to mod_example.c showing the format of a FLAG command
4988 *) Standardized the time format in mod_status to match that of other
4989 places in the code (e.g. DATE_GMT). PR#1551
4991 *) Fix handling of %Z in timefmt strings for those platforms with no time
4992 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
4995 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
4996 feature compatible with 'UseCanonicalName off' by changing
4997 r->server->server_hostname to ap_get_server_name(). And I changed some
4998 functions which use r->server->port to use ap_get_server_port() instead,
4999 because if there's no Port directive in the config r->server->port is 0.
5002 *) get/set_module_config are trivial enough to be better off inline. Worth
5003 1.5% performance boost. [Dean Gaudet]
5005 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
5006 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
5009 *) [BS2000 security] BS2000 needs an extra authentication to initialize
5010 the task environment to the unprivileged User id. Otherwise CGI scripts
5011 would have a way to gain super user access. [Martin Kraemer]
5013 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
5014 absolute path, only log base name of logging source as is done
5015 in unix. [Martin Kraemer]
5017 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
5018 the encoding type from the Accept-Encoding header (if it's there)
5019 and use it in the response, as that's probably what it'll be expecting.
5020 [Ronald.Tschalaer@psi.ch]
5022 *) Fix to mod_alias: translate_alias_redir is dealing with
5023 a URI, not a filename, so the check for drive letters for win32
5024 and emx is not necessary. [Dean Gaudet]
5026 *) WIN32: Allow .cmd as an executable extension.

5032 *) Child processes can now "signal" (by exiting with a status
5033 of APEXIT_CHILDFATAL) the parent process to abort and
5034 shutdown the server if the error in the child process was
5035 fatal enough. [Jim Jagielski]
5037 *) mod_autoindex's find_itme() was sensitive to MIME type case.
5038 [Jim Jagielski] PR#2112
5040 *) Make sure the referer_log and agent_log entries in the default httpd.conf

5044 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
5046 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
5049 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
5050 Additionally the checks for finding the vendor DSO library were moved
5051 from mod_so.c to Configure because first it needs $PLAT etc. and second
5052 mod_so already uses an abstraction layer and does not fiddle with the
5053 vendor functions itself.
5054 [Jens-Uwe Mager, Ralf S. Engelschall]
5056 *) PORT: Some optimization defines for NetBSD
5057 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
5059 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
5060 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
5062 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
5063 AIX variants should work fine, too. Even AIX 3.x should work). This is
5064 accomplished by using the free DSO emulation code from Jens-Uwe Mager
5065 which we put into a os/unix/os-dso-aix.c file.
5066 [Ralf S. Engelschall]
5068 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
5069 that we should use NET_SIZE_T == int but the include files force size_t.
5070 [Ralf S. Engelschall]
5072 *) Fix two bugs in select() handling in http_main.c.
5075 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
5076 is unset (as it is in situations like timeouts) where it is unclear
5077 whether errno is set or not. [Martin Kraemer]
5079 *) Just having APACI's localstatedir is too general and not enough for most
5080 of the systems. 1.3b6 again required manual APACI patches by package
5081 maintainers from RedHat and FreeBSD because for their filesystem layout a
5082 little bit more flexibility in configuring the paths is needed. Hence we
5083 provide three additional configure options (--runtimedir, --logfiledir,
5084 --proxycachedir) which now can be used for more granular adjustments if
5085 --localstatedir is not enough to fit the particular needs. As a nice
5086 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
5087 [Ralf S. Engelschall]
5089 *) Make the install root for "make install" in APACI's Makefile overrideable
5090 by package authors. This way we are even more friendly to package
5091 maintainers (especially Debian and RedHat) who build for the real prefix
5092 via "configure --prefix=/<real>" but use a different local prefix via
5093 "make root=/tmp/apache install" for rolling the package without bristling
5094 the target location on their system.
5095 [Ralf S. Engelschall]
5097 *) Workaround sed limitations in APACI's configure script by now
5098 substituting in chunks of 50 commands (because for instance HPUX's vendor
5099 sed has a limit of max. 98 commands)
5100 [Ralf S. Engelschall] PR#2136
5102 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
5103 [Ralf S. Engelschall] PR#2140
5105 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG

5107 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
5108 [Ralf S. Engelschall]
5110 *) Workaround braindead AWK's when generating ap_config.h: The split() and
5111 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
5112 [Ralf S. Engelschall] PR#2139
5114 *) Various bugfixes and cleanups for the APACI configure script:
5115 o fix IFS handling for _nested_ situation
5116 o fix Perl interpreter search: take first one found instead of last one
5117 o fix DSO consistency check
5118 o print error messages to stderr instead of stdout
5119 o add install-quiet for --shadow situation to Makefile stub
5120 o reduce complexity by avoiding sed-hacks for rule and module list loops

5123 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
5125 *) Make sure the input field separator (IFS) shell variable is explicitly
5126 initialized correctly before _every_ `for' loop and also restored after
5127 the loops. [Ralf S. Engelschall]
5129 *) Make sure that "make install" doesn't overwrite the `mime.types' and
5130 `magic' files from an existing Apache installation. Because people often
5131 customize these for own MIME and content types.

5135 [Peter Galbavy, Ralf S. Engelschall] PR#2109
5137 *) Fix the path to the ScoreBoardFile in the install-config target, too.
5138 [Ralf S. Engelschall] PR#2105
5140 *) Let "configure" clear out the users parameters (provided as shell

5142 exported them (which is not needed, but some users do it).
5143 [Ralf S. Engelschall] PR#2101
5145 *) Provide backward compatibility from some old src/Configuration.tmpl
5146 parameter names to the canonical Autoconf-style shell variable names. For
5147 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
5148 but a hint message is displayed. [Ralf S. Engelschall]

5151 CGI scripts from an existing Apache installation.
5152 [Ralf S. Engelschall, Jim Jagielski] PR#2084
5154 *) Make `configure --compat' more "compatible" by first
5155 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
5156 second by making sure the "avoid-bristling-suffix" /apache is not
5157 appended to sysconfdir, datadir, localstatedir and includedir when
5158 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]

5166 *) Fix the path to the MimeMagicFile in the install-config target, too.
5167 [Ralf S. Engelschall] PR#2089
5169 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
5171 *) If you start apache with the -S command line option it will dump
5172 out the parsed vhost settings. This is useful for folks trying
5173 to figure out what is wrong with their vhost configuration.
5174 (Other dumps may be added in the future.) [Dean Gaudet]
5176 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
5177 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
5180 *) Because /usr/local/apache is the default prefix the ``configure
5181 --compat'' option no longer has to set prefix, again. This way the
5182 --compat option honors a leading --prefix option. [Lars Eilebrecht]
5184 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
5185 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
5186 to avoid "discard const" warnings. [Ralf S. Engelschall]
5188 *) If a specific handler is set for a file yet the request still
5189 ends up being handled by the default handler, log an error
5190 message before handling it. This catches things such as trying
5191 to use SSIs without mod_include enabled. [Marc Slemko]
5193 *) Fix error logging for the startup case where ap_log_error() still uses
5194 stderr as the target. Now the default log level is honored here, too.
5195 [Ralf S. Engelschall]
5197 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
5198 long" errors when generating the MODULES entry for src/Makefile
5199 [Ben Hyde, Ralf S. Engelschall]
5201 *) Make sure src/Configure doesn't complain about the old directory
5202 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
5204 Changes with Apache 1.3b6
5206 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
5208 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
5209 interface via the similar but proprietary HP/UX shl_xxx-style system
5210 calls. [Ralf S. Engelschall]
5212 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
5213 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
5214 Make. [Ralf S. Engelschall]
5216 *) ++++ THE BIG SYMBOL RENAMING ++++
5217 To avoid symbol clashes with third-party code compiled into the server,
5218 we globally applied the prefix "ap_" to the following classes of
5220 - Apache provided general functions (e.g., ap_cpystrn)
5221 - Public API functions (e.g., palloc, bgets)
5222 - Private functions which we can't make static (because of
5223 cross-object usage) but should be (e.g., new_connection)
5224 For backward source compatibility a new header file named compat.h was
5225 created which provides defines for the old symbol names and can be used
5226 by third-party module authors.
5229 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
5230 problem under SVR4 is that there is no command flag to force the linker
5231 to export the global symbols of the httpd executable therewith they are
5232 available to the DSO's. Instead of problematic hacks like creating a
5233 dummy.so file (containing dummy references to all global symbols) the
5234 httpd binary is linked against, we use a clean trick stolen from Perl 5:
5235 Placing the Apache core code itself into a DSO library named libhttpd.so.
5236 This way the global symbols _HAVE_ to be exported and thus are available
5237 to any manually loaded DSO's under runtime. To reduce the impact to the
5238 user to null we go even further and create a stub httpd executable which
5239 automatically keeps track of the DSO library loading itself and thus
5240 hides the complete mechanism from the user. Although the generation of
5241 this DSO library is automatically triggered for platforms which
5242 essentially need it (mostly all SVR4-derivates) it can be also enabled
5243 manually via the Rule SHARED_CORE. This can be interesting in the future
5244 where we perhaps exploit this libhttpd.so mechanism for providing nifty
5245 features like graceful upgrades, or whatever.
5246 [Ralf S. Engelschall, Martin Kraemer]
5248 *) Build the libraries before building the rest of the tools. [Ben Hyde]
5250 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
5251 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
5252 conventions while "clean" removes only stuff created by "all" targets,
5253 "distclean" additionally removes the stuff from the configuration
5254 process. This way "make distclean" (hence the name) provides a fresh
5255 source tree as it was for distribution.
5256 [Ralf S. Engelschall]
5258 *) Allow top-level (APACI) Makefile to break on build errors
5259 the same way the src/ subtree Makefiles breaks on them by replacing the
5260 initial APACI sed-subdir-display-kludge with a more clean
5261 variable-passing-solution: variable SDP can optionally hold the subdir
5262 prefix which is consistently used for displaying the subdir movement.
5263 This way even the top-level Makefile can stop correctly on errors as the
5264 user expects. [Ralf S. Engelschall]
5266 *) Fixed ordering of argument checks for RewriteBase directive.
5267 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
5269 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
5270 indicating that a module is being compiled for dynamic loading. Also
5271 remove #define IS_MODULE from modules and add SHARED_MODULE define
5272 to the mak/dsp files. [Alexei Kosut]
5274 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
5275 since we are now logging APLOG_WARNING by default. [Roy Fielding]
5277 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
5279 *) Add documentation file and src/Configuration.tmpl entry for the
5280 experimental mod_mmap_static module. Because although it is and marked as
5281 an experimental one it is distributed and thus should be documented and
5282 prepared for configuration the same way as all others modules.
5283 [Ralf S. Engelschall]
5285 *) Add query (-q) option to apxs support tool to be able to manually query
5286 specific settings from apxs. This is needed for instance when you
5287 manually want to access Apache's header files and you need to assemble
5288 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
5289 [Ralf S. Engelschall]
5291 *) Now src/Configure uses a fallback strategy for the shared object support
5292 on platforms where no explicit information is available: If a Perl
5293 installation exists we ask it about its shared object support and if it's
5294 the dlopen-style one we shamelessly guess the compiler and linker flags
5295 for creating shared objects from Perls knowledge. Of course, the user is
5296 warning about what we are doing and informed that he should send us
5297 the guessed flags when they work. [Ralf S. Engelschall]
5299 *) Provide APACI --without-support option to be able to disable the build
5300 and installation of the support tools from the src/support/ area.
5301 Although its useful to have these installed per default we should provide
5302 a way to compile and install without them for backward-compatibility.
5303 [Ralf S. Engelschall]
5305 *) Add of the new APache eXtenSion (apxs) support tool for building and
5306 installing modules into an _already installed_ Apache package through the
5307 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
5308 this approach actually doesn't need the Apache source tree. The
5309 (APACI-installed) server package is enough, because this now includes the
5310 Apache C header files (PREFIX/include) and the new APXS tool
5311 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
5312 module authors to build their Apache modules _OUTSIDE_ the Apache source
5313 tree while avoiding them to fiddle around with the totally platform
5314 dependend way of compiling DSO files. The tool supports all ranges of
5315 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
5316 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
5317 on-the-fly generate a minimalistic Makefile and sample module for the
5318 first step to provide both a quick success event and to demonstrate the
5319 APXS mechanism to module authors. [Ralf S. Engelschall]
5321 *) Fix core dumps in use of CONNECT in proxy.
5322 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
5324 *) Modify the log directives in httpd.conf-dist files to use CustomLog
5325 so that users have examples of how CustomLog can be used.
5328 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
5329 the Apache distribution tree. Until Apache 1.3 there was no real
5330 out-of-the-box batch-capable build and installation procedure for the
5331 complete Apache package. This is now provided by a top-level "configure"
5332 script and a corresponding top-level "Makefile.tmpl" file. The goal is
5333 to provide a GNU Autoconf-style frontend which is capable to both drive
5334 the old src/Configure stuff in batch and additionally installs the
5335 package with a GNU-conforming directory layout. Any options from the old
5336 configuration scheme are available plus a lot of new options for flexibly
5337 customizing Apache. [Ralf S. Engelschall]
5339 *) The floating point ap_snprintf code wasn't threadsafe.
5340 Had to remove the HAVE_CVT macro in order to do threadsafe

5354 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
5355 a generic printf-style routine that can call arbitrary output
5356 routines. Use this to replace http_bprintf.c. Add new routines
5357 psprintf(), pvsprintf() which allocate the exact amount of memory
5358 required for a string from a pool. Use psprintf() to clean up
5359 various bits of code which used ap_snprintf()/pstrdup().
5362 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
5363 ap_snprintf() has different semantics and formatting codes than
5364 snprintf(). [Dean Gaudet]
5366 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
5367 is necessary on at least Solaris where the /etc/rc?.d scripts

5369 maintained across exec().

5397 *) Allow %2F in two situations: 1) it is in the query part of the URI,
5398 therefore not exposed to %2F -> '/' translations and 2) the request
5399 is a proxy request, so we're not dealing with a local resource anyway.
5400 Without this, the proxy would fail to work for any URL's with
5401 %2f in them (occurs quite often in

5434 document our stuff a little bit more and to be able to do really
5435 Unix-like installations ;-) [Ralf S. Engelschall]
5437 *) Major cleanups to the Configure script to make it and its generated
5438 Makefiles again readable and maintainable: add SRCDIR option, removed
5439 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
5440 generated sections, consequently added Makefile headers with inheritance
5441 information, added subdir movement messages for easier following where
5442 the build process currently stays (more verbose then standard Make, less
5443 verbose than GNU make), same style to comments in the Configure script,
5444 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
5446 *) Add the new ApacheBench program "ab" to src/support/: This is derived
5447 from the ZeusBench benchmarking program and can be used to determine the
5448 response performance of an Apache installation. This version is
5449 officially licensed with Zeus Technology, Ltd. See the license agreement

5455 more have been marked CORE_EXPORT and are not intended for general
5456 use by modules. [Doug MacEachern, Dean Gaudet]
5458 *) mod_proxy was not clearing the Proxy-Connection header from

5469 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
5471 *) Clean up some undocumented behavior of mod_setenvif related to
5472 "merging" two SetEnvIf directives when they match the same header
5473 and regex. Document that mod_setenvif will perform comparisons in
5474 the order they appear in the config file. Optimize mod_setenvif by
5475 doing more work at config time rather than at runtime.
5478 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
5479 to allow for modules to overrule them and to reduce redefinition
5480 warnings [Jim Jagielski]
5482 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
5485 *) Making the hard-coded cross-module function call mime_find_ct() (from
5486 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
5487 checking is really called even for proxy requests except for URLs with
5488 HTTP schemes (because there we can optimize by not running the type
5489 checking hooks due to the fact that the proxy gets the MIME Content-type
5490 from the remote host later). This change cleans up mod_mime by removing
5491 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
5492 especially unbundles mod_proxy and mod_mime. This way they both now can
5493 be compiled as shared objects and are no longer tied together.
5494 [Ralf S. Engelschall]
5496 *) util.c cleanup and speedup. [Dean Gaudet]
5498 *) API: Clarification, pstrndup() will always copy n bytes of the source

5501 *) Mark module command_rec and handler_rec structures const so that they

5503 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
5505 *) Add check to the "Port" directive to make sure the specified
5506 port is in the appropriate range. [Ben Hyde]
5508 *) Performance improvements to invoke_handler().
5509 [Dmitry Khrustalev <dima@bog.msu.su>]
5511 *) Added support for building shared objects even for library-style modules
5512 (which are built from more than one object file). This now provides the
5513 ability to build mod_proxy as a shared object module. Additionally
5514 modules like mod_example are now also supported for shared object
5515 building because the generated Makefiles now no longer assume there is at
5516 least one statically linked module. [Ralf S. Engelschall]
5518 *) API: Clarify usage of content_type, handler, content_encoding,
5519 content_language and content_languages fields in request_rec. They
5520 must always be lowercased; and the strings pointed to shouldn't
5521 be modified (you must copy them to modify them). Fix a few bugs
5522 related to this. [Dean Gaudet]
5524 *) API: Clarification: except for RAW_ARGS, all command handlers can
5525 treat the char * parameters as permanent, and modifiable. There
5526 is no need to pstrdup() them. Clean up some needless pstrdup().
5529 *) Now mod_so keeps track of which module shared objects with which names
5530 are loaded and thus avoids multiple loading and unloading and irritating
5531 error_log messages. [Ralf S. Engelschall]
5533 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
5534 environment variable in the apache core. But that tweaking interferes
5535 with mod_setenv. So don't tweak if the user has specified an explicit
5536 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888

5546 *) Various improvements to the configuration and build support for compiling
5547 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
5548 OSF1 support with GCC and vendor compilers was added. This way shared
5549 object support is now provided out-of-the-box for FreeBSD, Linux,
5550 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
5551 [Ralf S. Engelschall]
5553 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
5554 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
5555 and USE_OS2_SCOREBOARD. [Dean Gaudet]
5557 *) Fix one more special locking problem for RewriteMap programs in
5558 mod_rewrite: According to the documentation of flock(), "Locks are on
5559 files, not file descriptors. That is, file descriptors duplicated
5560 through dup(2) or fork(2) do not result in multiple instances of a lock,
5561 but rather multiple references to a single lock. If a process holding a
5562 lock on a file forks and the child explicitly unlocks the file, the
5563 parent will lose its lock.". To overcome this we have to make sure the
5564 RewriteLock file is opened _AFTER_ the childs were spawned which is now
5565 the case by opening it in the child_init instead of the module_init API
5566 hook. [Ralf S. Engelschall] PR#1029
5568 *) Change to Location and LocationMatch semantics. LocationMatch no
5569 longer lets a single slash match multiple adjacent slashes in the
5570 URL. This change is for consistency with RewriteRule and
5571 AliasMatch. Multiple slashes have meaning in URLs that they do
5572 not have in (some) filesystems. Location on the other hand can
5573 be considered a shorthand for a more complicated regex, and it
5574 does match multiple slashes with a single slash -- which is
5575 also consistent with the Alias directive.

5578 *) Fix bug with mod_mime_magic causing certain files, including files
5579 of length 0, to result in no response from the server.
5582 *) The Configure script now generates src/include/ap_config.h which
5583 contains the set of defines used when Apache is compiled on a platform.
5584 This file can then be included by external modules before including
5585 any Apache header files in case they are being built separately from
5586 Apache. Along with this change, a couple of minor changes were
5587 made to make Apache's #defines coexist peacefully with any autoconf
5588 defines an external module might have. [Rasmus Lerdorf]
5590 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
5591 but without any RewriteXXXXX directives. Here mod_rewrite is given no
5592 chance by the API to initialize its per-server configuration and thus
5593 receives the wrong one from the main server. This is now avoided by
5594 remembering the server together with the config structure while
5595 configuring and later assuming there is no config when we see a
5596 difference between the remembered server and the one calling us.
5597 [Ralf S. Engelschall] PR#1790
5599 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
5600 is automatically disabled under configure time when the dbm_xxx functions
5601 are not available. Second, two heavy source code errors in the DBM
5602 support code were fixed. This makes DBM RewriteMap's usable again after
5603 a long time of brokenness. [Ralf S. Engelschall] PR#1696
5605 *) Now all configuration files support Unix-style line-continuation via
5606 the trailing backslash ("\") character. This enables us to write down
5607 complex or just very long directives in a more readable way. The
5608 backslash character has to be really the last character before the
5609 newline and it has not been prefixed by another (escaping) backslash.

5621 *) WIN32: Preserve trailing slash in canonical path (and hence
5622 in PATH_INFO). [Paul Sutton, Ben Laurie]
5624 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
5625 depending on the rev of Solaris and what mixture of modules
5626 are in use. So it has been disabled, and Solaris is back to
5627 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
5628 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
5629 up static content only servers. Or it may fail unpredictably.

5632 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
5635 *) API: Rewrite of absoluteURI handling, and in particular how
5636 absoluteURIs match vhosts. Unless a request is a proxy request, a
5637 "http://host" url is treated as if a similar "Host:" header had been
5638 supplied. This change was made to support future HTTP/1.x protocols
5639 which may require clients to send absoluteURIs for all requests.
5641 In order to achieve this change subtle changes were made to the API. In a
5642 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
5643 that the unmodified uri can be retrieved easily. r->proxyreq is not set
5644 by the core, modules must set it during the post_read_request or
5645 translate_names phase.
5647 Plus changes to the virtualhost test suite for absoluteURI testing.
5649 This fixes several bugs with the proxy proxying requests to vhosts
5650 managed by the same httpd.
5653 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
5654 code from mod_rewrite. The vhost matching is now performed by a
5655 globally available function matches_request_vhost(). [Dean Gaudet]

5671 *) API: A new source module main/util_uri.c; It contains a routine
5672 parse_uri_components() and friends which breaks a URI into its component
5673 parts. These parts are stored in a uri_components structure called
5674 parsed_uri within each request_rec, and are available to all modules.
5675 Additionally, an unparse routine is supplied which re-assembles the URI
5676 components back to an URI, optionally hiding the username:password@ part
5677 from ftp proxy requests, and other useful routines. Within the structure,
5678 you find on a ready-for-use basis:
5679 scheme; /* scheme ("http"/"ftp"/...) */
5680 hostinfo; /* combined [user[:password]@]host[:port] */
5681 user; /* user name, as in http://user:passwd@host:port/ */
5682 password; /* password, as in http://user:passwd@host:port/ */
5683 hostname; /* hostname from URI (or from Host: header) */
5684 port_str; /* port string (integer representation is in "port") */
5685 path; /* the request path (or "/" if only scheme://host was given) */
5686 query; /* Everything after a '?' in the path, if present */
5687 fragment; /* Trailing "#fragment" string, if present */
5688 This is meant to serve as the platform for *BIG* savings in
5689 code complexity for the proxy module (and maybe the vhost logic).
5692 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
5693 ${map:key}) available for all location where a string is created in
5694 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of

5696 possible expansions are consequently usable at all string creation
5697 locations. [Ralf S. Engelschall]

5702 completely overridden (default) or completely inherited (when
5703 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

5734 type but with a special post-processing for the looked-up value: It
5735 parses it into alternatives according to `|' chars and then only one
5736 particular alternative is chosen randomly (this is an essential
5737 functionality needed for balancing between backend-servers when using
5738 Apache as a Reverse Proxy. The looked up value here is a list of
5739 servers). Second, `int' with the built-in maps named `tolower' and
5740 `toupper' which can be used to map URL parts to a fixed case (this is an
5741 essential feature to fix the case of server names when doing mass
5742 virtual-hosting with the help of mod_rewrite instead of using
5743 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from

5746 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
5747 This directive lets Apache adjust the URL in Location-headers on HTTP
5748 redirect responses sent by the remote server. This way the virtually
5749 mapped area is no longer left on redirects and thus by-passed which is
5750 especially essential when running Apache as a reverse proxy.

5830 *) SECURITY: "UserDir /abspath" without a * in the path would allow
5831 remote users to access "/~.." and bypass access restrictions
5832 (but note /~../.. was handled properly).
5833 [Lauri Jesmin <jesmin@ut.ee>] PR#1701
5835 *) API: os_is_path_absolute() now takes a const char * instead of a char *.
5838 Changes with Apache 1.3b5
5840 *) Source file dependencies in Makefile.tmpl files throughout the
5841 source tree were updated to accurately reflect reality.
5844 *) Preserve the content encoding given by the AddEncoding directive
5845 when the client doesn't otherwise specify an encoding.
5846 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>]
5848 *) Sort out problems with canonical filename handling happening too late.
5849 [Dean Gaudet, Ben Laurie]
5851 Changes with Apache 1.3b4
5853 *) The module structure was modified to include a *dynamic_load_handle
5854 in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
5855 has been bumped accordingly. [Paul Sutton]
5857 *) All BrowserMatch directives mentioned in
5858 htdocs/manual/known_client_problems.html are in the default
5859 configuration files. [Lars Eilebrecht]
5861 *) MiNT port update. [Jan Paul Schmidt]
5863 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
5864 equivalent, similarly for x-compress and compress. Apache
5865 now ignores a leading x- when comparing encodings. It also
5866 preserves the encoding the client requests (for example if
5867 it requests x-gzip, then Apache will respond with x-gzip
5868 in the Content-Encoding header).
5869 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1772
5871 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
5873 *) Added mod_so module to support dynamic loading of modules on Unix
5874 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
5875 instead of AddModule in Configuration to build shared modules
5876 [Sameer Parekh, Paul Sutton]
5878 *) Minor cleanups to r->finfo handling in some modules.
5881 *) Abstract read()/write() to ap_read()/ap_write().
5882 Makes it easier to add other types of IO code such as SFIO.
5885 *) API: Generalize default_port manipulations to make support of
5886 different protocols easier. [Ben Laurie, Randy Terbush]
5888 *) There are many cases where users do not want Apache to form
5889 self-referential urls using the "canonical" ServerName and Port.
5890 The new UseCanonicalName directive (default on), if set to off
5891 will cause Apache to use the client-supplied hostname and port.
5892 API: Part of this change required a change to the construct_url()
5893 prototype; and the addition of get_server_name() and
5895 [Michael Douglass <mikedoug@texas.net>, Dean Gaudet]
5896 PR#315, 459, 485, 1433
5898 *) Yet another rearrangement of the source tree.. now all the common
5899 header files are in the src/include directory. The -Imain -Iap
5900 references in Makefiles have been changed to the simpler -Iinclude
5901 instead. In addition to simplifying the build a little bit, this
5902 also makes it clear when a module is referencing something in a
5903 other than kosher manner (e.g., the proxy including mod_mime.h).
5904 Module-private header files (the proxy, mod_mime, the regex library,
5905 and mod_rewrite) have not been moved to src/include; nor have
5906 the OS-abstraction files. [Ken Coar]
5908 *) Fix a bug where r->hostname didn't have the :port stripped
5909 from it. [Dean Gaudet]
5911 *) Tweaked the headers_out table size, and the subprocess_env
5912 table size guess in rename_original_environment(). Added
5913 MAKE_TABLE_PROFILE which can help discover make_table()
5914 calls that use too small an initial guess, see alloc.c.
5917 *) Options and AllowOverride weren't properly merging in the main
5918 server setting inside vhosts (only an issue when you have no
5919 <Directory> or other section containing an Options that affects
5920 a request). Options +foo or -foo in the main_server wouldn't
5921 affect the main_server's lookup defaults. [Dean Gaudet]
5923 *) Variable 'cwd' was being used pointlessly before being set.
5926 *) r->allowed handling cleaned up in the standard modules.
5929 *) Some case-sensitivity issues cleaned up to be consistent with
5930 RFC2068. [Dean Gaudet]
5932 *) SIGURG doesn't exist everywhere.
5933 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
5935 *) mod_unique_id was erroneously generating a second unique id when
5936 an internal redirect occured. Such redirects occur, for example,
5937 when processing a DirectoryIndex match. [Dean Gaudet]
5939 *) API: table_add, table_merge, and table_set include implicit pstrdup()
5940 of the key and value. But in many cases this is not required
5941 because the key/value is a constant, or the value has been built
5942 by pstrcat() or other similar means. New routines table_addn,
5943 table_mergen, and table_setn have been added to the API, these
5944 routines do not pstrdup() their arguments. The core code and
5945 standard modules were changed to take advantage of these routines.
5946 The resulting server is up to 20% faster in some situations.
5948 Note that it is easy to get code subtly wrong if you pass a key/value
5949 which is in a pool other than the pool of the table. The only
5950 safe thing to do is to pass key/values which are in the pool of
5951 the table, or in one of the ancestors of the pool of the table.
5952 i.e. if the table is part of a subrequest, a value from the main
5953 request's pool is OK since the subrequest pool is a sub_pool of the
5954 main request's pool (and therefore has a lifespan at most as long as
5955 the main pool). There is debugging code which can detect improper
5956 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
5957 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
5959 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
5960 which don't exist on disk more gracefully; handles vhosts properly.
5961 Update documentation to reflect the code -- if there's no
5962 MimeMagicFile directive then the module is not enabled.
5965 *) PORT: Some older *nix dialects cannot automatically start scripts
5966 which begin with a #! interpreter line (the shell starts the scripts
5967 appropriately on these platforms). Apache now supports starting of
5968 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
5969 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
5972 *) API: "typedef array_header table" removed from alloc.h, folks should
5973 have been writing to use table as if it were an opaque type, but even
5974 some standard modules got this wrong. By changing the definition
5975 to "typedef struct table table" module authors will receive compile
5976 time warnings that they're doing the wrong thing. This change
5977 facilitates future changes with more sophisticated table
5978 structures. Specifically, module authors should be using table_elts()
5979 to get access to an array_header * for the table. [Dean Gaudet]
5981 *) API: Renamed new_connection() to avoid namespace collision with LDAP
5982 library routines. [Ken Coar, Rasmus Lerdorf]
5984 *) WIN32: mod_speling is now available on the Win32 platform.
5987 *) For clarity the following compile time definition was changed:
5989 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
5991 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
5992 and not be a general notice that the OS has mmap(). Now the
5993 HAVE_MMAP/SHMGET #defines strictly are informational that the
5994 OS has that method of shared memory; the type to use for
5995 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
5996 and USE_SHMGET_SCOREBOARD). This allows outside modules to
5997 determine if shared memory is available and allows Apache
5998 to determine the best method to use for the scoreboard.
6001 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
6002 as do various earlier versions. It should be safe on all versions.
6003 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
6004 the slack code. A few other cleanups for Unixware.

6007 *) PORT: A/UX can handle single-listen accepts without mutex
6008 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
6010 *) When die() happens we need to eat any request body if one exists.
6011 Otherwise we can't continue with a keepalive session. This shows up
6012 as a POST problem with MSIE 4.0, typically against pages which are
6013 authenticated. [Roy Fielding] PR#1399
6015 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
6016 header will be passed to CGIs. This is generally a security hole, so
6017 it's not a default. [Marc Slemko] PR#549
6019 *) Fix Y2K problem with date printing in suexec log.
6020 [Paul Eggert <eggert@twinsun.com>] PR#1343
6022 *) WIN32 deserves a pid file. [Ben Hyde]
6024 *) suexec errors now include the errno/description. [Marc Slemko] PR#1543
6026 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
6027 The choice of flock vs. fcntl was made based on timings which showed that
6028 even on non-NFS, non-exported filesystems fcntl() was an order of
6029 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
6030 that single socket users will see no difference. [Dean Gaudet] PR#467
6032 *) "File does not exist" error message was erroneously including the
6033 errno. [Marc Slemko]
6035 *) Improve the warning message generated when a client drops the
6036 connection (hits stop button, etc.) during a send. [Roy Fielding]
6038 *) Defining GPROF will disable profiling in the parent and enable it
6039 in the children. If you're profiling under Linux this is pretty much
6040 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
6042 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.
6045 *) The NeXT cc (which is gcc hacked up) doesn't appear to support some
6046 gcc functionality. Work around it.
6047 [Keith Severson <keith@sssd.navy.mil>] PR#1613
6049 *) Some linkers complain when .o files contain no functions.
6050 [Keith Severson <keith@sssd.navy.mil>] PR#1614
6052 *) Some const declarations in mod_imap.c that were added for debugging
6053 purposes caused some compilers heartburn without adding any
6054 significant value, so they've been removed. [Ken Coar]
6056 *) The src/main/*.h header files have had #ifndef wrappers added to
6057 insulate them against duplicate calls if they get included through
6058 multiple paths (e.g., in .c files as well as other .h files).
6061 *) The libap routines now have a header file for their prototypes,
6062 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
6064 *) mod_autoindex with a plaintext header file would emit the <PRE>
6065 start-tag before the HTML preamble, rather than after the preamble
6066 but before the header file contents. [John Van Essen <jve@gamers.org>]
6069 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
6070 only an issue on systems without a MAXDNAME define or where
6071 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
6073 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
6074 is used to read various types of files such as htaccess and
6075 htpasswd files. [Marc Slemko]
6077 *) SECURITY: Ensure that the buffer returned by ht_time is always
6078 properly null terminated. [Marc Slemko]
6080 *) The "Connection" header could be sent back with multiple "close"
6081 tokens. Not an error, but a waste.
6082 [Ronald.Tschalaer@psi.ch] PR#1683
6084 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
6085 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
6087 *) "basic" auth needs a case-insensitive comparison.
6088 [Ronald.Tschalaer@psi.ch] PR#1666
6090 *) For maximum portability, the environment passed to CGIs should
6091 only contain variables whose names match the regex
6092 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
6093 underscores over any character outside the regex. This
6094 affects HTTP_* variables, in a way that should be backward
6095 compatible for all the standard headers; and affects variables
6096 set with SetEnv/BrowserMatch and similar directives.
6099 *) mod_speling returned incorrect HREF's when an ambigous match
6100 was found. Noticed by <robinton@amtrash.comlink.de> (Soeren Ziehe)
6101 [robinton@amtrash.comlink.de (Soeren Ziehe), Martin Kraemer]
6103 *) PORT: Apache now compiles & runs on an EBCDIC mainframe
6104 (the Siemens BS2000/OSD family) in the POSIX subsystem
6107 *) PORT: Fix problem killing children when terminating. Allow ^C
6108 to shut down the server. [Brian Havard]
6110 *) pstrdup() is implicit in calls to table_* functions, so there's
6111 no need to do it before calling. Clean up a few cases.
6112 [Marc Slemko, Dean Gaudet]
6114 *) new -C and -c command line arguments

6125 [Marc Slemko] PR#1591
6127 *) WIN32: Fix a call to os_canonical_filename so it doesn't try to
6128 mess with fake filenames. This fixes proxy caching on
6131 *) SECURITY: General mod_include cleanup, including fixing several
6132 possible buffer overflows and a possible infinite loop.
6133 [Dean Gaudet, Marc Slemko]
6135 *) SECURITY: Numerous changes to mod_imap in a general cleanup
6136 including fixing a possible buffer overflow. [Dean Gaudet]
6138 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful
6139 (connections are not dropped). Code can handle graceful restarts
6140 (but there is as yet no way to signal this to Apache). Various
6141 other cleanups. [Paul Sutton]
6143 *) The aplog_error changes specific to 1.3 introduced a buffer
6144 overrun in the (now legacy) log_printf function. Fixed.
6147 *) mod_digest didn't properly deal with proxy authentication. It
6148 also lacked a case-insensitive comparision of the "Digest"
6149 token. [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1599
6151 *) A few cleanups in mod_status for efficiency. [Dean Gaudet]
6153 *) A few cleanups in mod_info to make it thread-safe, and remove an
6154 off-by-5 bug that could hammer \0 on the stack. [Dean Gaudet]
6156 *) no2slash() was O(n^2) in the length of the input. Make it O(n).
6159 *) API: migration from strncpy() to our "enhanced" version called
6160 ap_cpystrn() for performance and functionality reasons.
6161 Located in libap.a. [Jim Jagielski]
6163 *) table_set() and table_unset() did not deal correctly with
6164 multiple occurrences of the same key.
6165 [Stephen Scheck <sscheck@infonex.net>, Ben Laurie] PR#1604
6167 *) The AuthName must now be enclosed in quotes if it is to contain
6168 spaces. [Ken Coar] PR#1195
6170 *) API: new function: ap_escape_quotes(). [Ken Coar] PR#1195
6172 *) WIN32: Work around optimiser bug that killed ISAPI in release
6173 versions. [Ben Laurie] PR#1533
6175 *) PORT: Update the MPE port [Mark Bixby, Jim Jagielski]
6177 *) Interim (slow) fix for p->sub_pool critical sections in
6178 alloc.c (affects win32 only). [Ben Hyde]
6180 *) non-WIN32 was missing destroy_mutex definition. [Ben Hyde]
6182 *) send_fd_length() did not calculate total_bytes_sent properly.
6183 [Ben Reser <breser@regnow.com>] PR#1366
6185 *) The bputc() macro was not properly integrated with the chunking
6186 code; in many cases modules using bputc() could cause completely
6187 bogus chunked output. (Typically this will show up as problems
6188 with Internet Explorer 4.0 reading a page, but other browsers
6189 having no problem.) [Dean Gaudet]
6191 *) Create LARGE_WRITE_THRESHOLD define which determines how many
6192 bytes have to be supplied to bwrite() before it will consider
6193 doing a writev() to assemble multiple buffers in one system
6194 call. This is critical for modules such as mod_include,
6195 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
6196 strings in some cases. The result would be extra effort
6197 setting up writev(), and in many cases extra effort building
6198 chunks. The default is 31, it can be overriden at compile
6201 *) Move the gid switching code into the child so that log files
6202 and pid files are opened with the root gid.
6203 [Gregory A Lundberg <lundberg@vr.net>]

6206 instead of counting control characters.
6207 [Jim Patterson <Jim.Patterson@Cognos.COM>] PR#1340
6209 *) ap_snprintf() moved from main/util_snprintf.c to ap/ap_snprintf.c
6210 so the functionality is available to applications other than the
6211 server itself (like the src/support tools). [Ken Coar]
6213 *) ap_slack() moved out of main/util.c into ap/ap_slack.c as part of
6214 the libap consolidation work. [Ken Coar]
6216 *) ap_snprintf() with a len of 0 behaved like sprintf(). This is not
6217 useful, and isn't what the standards require. Now it returns 0

6318 *) It was necessary to distinguish between resources which are
6319 allocated in the parent, for cleanup in the parent, and resources
6320 which are allocated in each child, for cleanup in each child.
6321 A new pool was created which is passed to the module child_init
6322 and child_exit functions; modules are free to register per-child
6323 cleanups there. This fixes a bug with reliable piped logs.
6326 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
6327 unless it was also doing FancyIndexes, but it displayed the
6328 HeaderName file at the top under all circumstances. It now shows
6329 the ReadmeName file for simple indices, too, as it should.
6332 *) http_core was mmap()ing even in cases where it wasn't going to
6333 read the file. [Ben Hyde <bhyde@gensym.com>]
6335 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
6336 Now the rewriting engine (the heart of mod_rewrite) is organized more
6337 straight-forward, first time well documented and reduced to the really
6338 essential parts. All redundant cases were stripped off and processing now
6339 is the same for both per-server and per-directory context with only a
6340 minimum difference (the prefix stripping in per-dir context). As a
6341 side-effect some subtle restrictions and two recently discovered problems
6342 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
6343 context and restrictions on the substitution URL on redirects.
6344 Additionally some minor source cleanups were done.

6499 Changes with Apache 1.3b2 (there is no 1.3b1)
6501 *) TestCompile was not passing $LIBS [Dean Gaudet]
6503 *) Makefile.tmpl was not using $CFLAGS in the link phase.
6506 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
6507 rudimentary memory debugger which can be used on live servers with
6508 low impact -- it sets all allocated and freed memory bytes to 0xa5.
6509 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
6510 and free() for each object. This is far more expensive and should
6511 only be used for testing with tools such as Electric Fence and
6512 Purify. See main/alloc.c for more details. [Dean Gaudet]
6514 *) Configure uses a sh trap and didn't set its exitcode properly.
6515 [Dean Gaudet] PR#1159
6517 *) Yet another vhost revamp. Add the NameVirtualHost directive which
6518 explicitly lists the ip:port pairs that are to be used for name-vhosts.
6519 From a given ip:port, regardless what the Host: header is, you can
6520 only reach the vhosts defined on that ip:port. The precedence of
6521 vhosts was reversed to match other precedences in the config --
6522 the earlier vhosts override the later vhosts. All vhost matching was
6523 moved into http_vhost.[ch]. [Dean Gaudet]
6525 *) ap_inline can be used to force inlining. GNUC __attribute__() can
6526 be used for whatever reason is appropriate (i.e. format() warnings
6527 for printf style functions). Both are enabled only with
6528 gcc >= 2.7.x (so that we have fewer support issues with older
6529 versions). [Dean Gaudet]
6531 *) Fix support for Proxy Authentication (we were testing the response
6532 status too early). [Marc Slemko]
6534 *) CoreDumpDirectory directive directs where the core file is
6535 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
6536 received. [Marc Slemko, Dean Gaudet]
6538 *) PORT: Support for Atari MINT.
6539 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
6541 *) When booting, apache will now detach itself from stdin, stdout,
6542 and stderr. stderr will not be detached until after the config
6543 files have been read so you will be able to see initial error
6544 messages. After that all errors are logged in the error_log.
6545 This makes it more convenient to start apache via rsh, ssh,
6546 or crontabs. [Dean Gaudet] PR#523
6548 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
6549 Also removed the auto-generated link to www.apache.org that was the
6550 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
6552 *) send_fb would not detect aborted connections in some situations.
6555 *) mod_include would use uninitialized data when parsing certain
6556 expressions involving && and ||. [Brian Slesinsky] PR#1139
6558 *) mod_imap should only handle GET methods. [Jay Bloodworth]
6560 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
6562 *) mod_autoindex improperly counted &escapes; as more than one
6563 character in the description. It also improperly truncated
6564 descriptions that were exactly the maximum length.
6567 *) RedirectMatch was not properly escaping the result (PR#1155). Also
6568 "RedirectMatch /advertiser/(.*) $1" is now permitted.
6571 *) mod_include now uses symbolic names to check for request success
6572 and return HTTP errors, and correctly handles all types of
6573 redirections (previously it only did temporary redirect correctly).
6574 [Ken Coar, Roy Fielding]
6576 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
6577 r->filename. Since those two are meant to be in sync with each other
6578 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
6580 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
6581 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]
6583 *) Inetd mode (which is buggy) uses timeouts without having setup the
6584 jmpbuffer. [Dean Gaudet] PR#1064
6586 *) Work around problem under Linux where a child will start looping
6587 reporting a select error over and over.
6588 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
6590 *) Fixed error in proxy_util.c when looping through multiple host IP
6591 addresses. [Lars Eilebrecht] PR#974
6593 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
6594 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
6595 bytes before writing, but it will never split a log entry across a
6596 buffer boundary. [Dean Gaudet]
6598 *) API: the short_score record has been split into two pieces, one which
6599 the parent writes on, and one which the child writes on. As part of
6600 this change the get_scoreboard_info() function was removed, and
6601 scoreboard_image was exported. This change fixes a race condition
6602 in file based scoreboard systems, and speeds up changes involving the
6603 scoreboard in earlier 1.3 development. [Dean Gaudet]
6605 *) API: New register_other_child() API (see http_main.h) which allows
6606 modules to register children with the parent for maintenance. It
6607 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
6609 *) API: New piped_log API (see http_log.h) which implements piped logs,
6610 and will use register_other_child to implement reliable piped logs
6611 when it is available. The reliable piped logs part can be disabled
6612 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
6613 logs is only available on Unix. [Dean Gaudet]
6615 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
6616 meets_conditions(). This allows conditional HTTP selection to be
6617 handled separately from the storing of the header fields, and provides
6618 the ability for CGIs to set their own ETags for conditional checking.
6619 [Ken Coar, Roy Fielding] PR#895
6621 *) Changes to mod_log_config to allow naming of format strings.
6622 Format nicknames are defined with "LogFormat fmt nickname", and can
6623 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
6626 *) New module, "mod_speling", which can help find files even when
6627 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
6629 *) API: New function child_terminate() triggers the child process to
6630 exit, while allowing the child finish what it needs to for the
6631 current request first.
6632 [Doug MacEachern, Alexei Kosut]
6634 *) Windows now defaults to using full status reports with mod_status.
6635 [Alexei Kosut] PR #1094
6637 *) *Really* disable all mod_rewrite operations if the engine is off.
6638 Some things (like RewriteMaps) were checked/performed even if they
6639 weren't supposed to be. [Ken Coar] PR #991
6641 *) Implement a new timer scheme which eliminates the need to call alarm() all
6642 the time. Instead a counter in the scoreboard for each child is used to
6643 show when the child has made forward progress. The parent samples this
6644 counter every scoreboard maintenance cycle, and issues SIGALRM if no
6645 progress has been made in the timeout period. This reduces the static
6646 request best-case syscall count to 22 from 29. This scheme is only
6647 used by systems with memory-based scoreboards. [Dean Gaudet]
6649 *) The proxy now properly handles CONNECT requests which are sent
6650 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
6652 *) A script called apachectl has been added to the support
6653 directory. This script allows you to do things such as
6654 "apachectl start" and "apachectl restart" from the command
6657 *) Modules and core routines are now put into libraries, which
6658 simplifies the link line tremendously (among other advantages).
6661 *) Some of the MD5 names defined in Apache have been renamed to have
6662 an `ap_' prefix to avoid conflicts with routines supplied by
6663 external libraries. [Ken Coar]
6665 *) Removal of mod_auth_msql.c from the distribution. There are many
6666 other options for databases today. Rather than offer one option,
6667 offer none at this time. mod_auth_msql and other SQL database
6668 authentication modules can be found at the Apache Module Registry.
6669 http://modules.apache.org/ It would be nice to offer a generic
6670 mod_auth_sql option in the near future.
6672 *) PORT: BeOS support added [Alexei Kosut]
6674 *) Configure no longer accepts the -make option, since it creates
6675 Makefile on the fly based on Makefile.tmpl and Configuration.
6677 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
6678 of forcibly killing off all its processes and exiting without
6679 cleaning up. [Alexei Kosut]
6681 *) API: A new field in the request_rec, r->mtime, has been added to
6682 avoid gratuitous parsing of date strings. It is intended to hold
6683 the last-modified date of the resource (if applicable). An
6684 update_mtime() routine has also been added to advance it if
6685 appropriate. [Roy Fielding, Ken Coar]
6687 *) SECURITY: If a htaccess file can not be read due to bad permissions,
6688 deny access to the directory with a HTTP_FORBIDDEN. The previous
6689 behavior was to ignore the htaccess file if it could not be read.
6690 This change may make some setups with unreadable htaccess files
6691 stop working. [Marc Slemko] PR#817
6693 *) Add aplog_error() providing a mechanism to define levels of
6694 verbosity to the server error logging. This addition also provides
6695 the ability to log errors using syslogd. Error logging is configurable
6696 on a per-server basis using the LogLevel directive. Conversion
6697 of log_*() in progress. [Randy Terbush]
6699 *) Further enhance aplog_error() to not log filename, line number, and
6700 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
6702 *) WIN32: Canonicalise filenames under Win32. Short filenames are
6703 converted to long ones. Backslashes are converted to forward
6704 slashes. Case is converted to lower. Parts of URLs that do not
6705 correspond to files are left completely alone. [Ben Laurie]
6707 *) PORT: 2 new OSs added to the list of ports:
6708 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
6709 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
6711 *) Add the server version (SERVER_VERSION macro) to the "server
6712 configured and running" entry in the error_log. Also build an
6713 object file at link-time that contains the current time
6714 (SERVER_BUILT global const char[]), and include that in the
6717 *) Set r->headers_out when sending responses from the proxy.
6718 This fixes things such as the logging of headers sent from
6719 the proxy. [Marc Slemko] PR#659
6721 *) support/httpd_monitor is no longer distributed because the
6722 scoreboard should not be file based if at all possible. Use
6723 mod_status to see current server snapshot.
6725 *) (set_file_slot): New function, allowing auth directives to be
6726 independent of the server root, so the server documents can be
6727 moved to a different directory or machine more easily.
6728 [David J. MacKenzie]
6730 *) If no TransferLog is given explicitly, decline
6731 to log. This supports coexistence with other logging modules,
6732 such as the custom one that UUNET uses. [David J. MacKenzie]
6734 *) Check for titles in server-parsed HTML files.
6735 Ignore leading newlines and returns in titles. The old behavior
6736 of replacing a newline after <title> with a space causes the
6737 title to be misaligned in the listing. [David J. MacKenzie]
6739 *) Change mod_cern_meta to be configurable on a per-directory basis.
6740 [David J. MacKenzie]
6742 *) Add 'Include' directive to allow inclusion of configuration
6743 files within configuration files. [Randy Terbush]
6745 *) Proxy errors on connect() are logged to the error_log (nothing
6746 new); now they include the IP address and port that failed
6747 (*that's* new). [Ken Coar, Marc Slemko] PR#352
6749 *) Various architectures now define USE_MMAP_FILES which causes
6750 the server to use mmap() for static files. There are two
6751 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
6752 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
6753 number of bytes written in one cycle from a single mmap()d object,
6754 default 32768). [Dean Gaudet]
6756 *) API: Added post_read_request API phase which is run right after reading
6757 the request from a client, or right after an internal redirect. It is
6758 useful for modules setting environment variables that depend only on
6759 the headers/contents of the request. It does not run during subrequests
6760 because subrequests inherit pretty much everything from the main
6761 request. [Dean Gaudet]
6763 *) Added mod_unique_id which is used to generate a unique identifier for
6764 each hit, available in the environment variable UNIQUE_ID.
6767 *) init_modules is now called after the error logs have been opened. This
6768 allows modules to emit information messages into the error logs.
6771 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
6772 information for case where proxy module is not available. [Marc Slemko]
6774 *) PORT: Apache has need for mutexes to serialize its children around
6775 accept. In prior versions either fcntl file locking or flock file
6776 locking were used. The method is chosen by the definition of
6777 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
6778 and FLOCK for flock(). New options have been added:
6779 - SYSVSEM to use System V style semaphores
6780 - PTHREAD to use POSIX threads (appears to work on Solaris only)
6781 - USLOCK to use IRIX uslock
6782 Based on timing various techniques, the following changes were made
6784 - Linux 2.x uses flock instead of fcntl
6785 - Solaris 2.x uses pthreads
6786 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
6787 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
6788 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
6789 Martijn Koster <m.koster@pobox.com>]
6791 *) PORT: The semantics of accept/select make it very desirable to use
6792 mutexes to serialize accept when multiple Listens are in use. But
6793 in the case where only a single socket is open it is sometimes
6794 redundant to serialize accept(). Not all unixes do a good job with
6795 potentially dozens of children blocked on accept() on the same
6796 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
6797 the server will avoid serialization when listening on only one socket,
6798 and use serialization when listening on multiple sockets.
6799 [Dean Gaudet] PR#467
6801 *) Configure changes: TestLib replaced by TestCompile, which has
6802 some additional capability (such as doing a sanity check of
6803 the compiler and flags selected); the version of Solaris is now
6804 available via the #define value of SOLARIS2; IRIX n32bit libs
6805 now supported and selectable by new Configuration Rule: IRIXN32;
6806 We no longer default to -O2 optimization. [Jim Jagielski]
6808 *) Updated Configure: Configuration now uses AddModule to specify
6809 module source or binary file location, relative to src directory.
6810 Modules can be dropped into modules/extra, or in their own
6811 directory, and modules can come with a Makefile or Configure can
6812 create one. Modules can add compiler or library information to
6813 generated Makefiles. [Paul Sutton]
6815 *) Source core re-organisation: distributed modules are now in
6816 modules/standard. All other source code is in main. OS-specific
6817 code is in os/{unix,emx,win32} directories. [Paul Sutton]
6819 *) mod_browser has been removed, since it's replaced by mod_setenvif.
6822 *) Fix another long-standing bug in sub_req_lookup_file where it would
6823 happily skip past access checks on subdirectories looked up with
6824 relative paths. (It's used by mod_dir, mod_negotiation,
6825 and mod_include.) [Dean Gaudet]
6827 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
6828 N is the number of <Directory> sections, and M is the number of
6829 components in the filename of an object.
6831 To achieve this optimization the following config changes were made:
6832 - Wildcards (* and ?, not the regex forms) in <Directory>s,
6833 <Files>s, and <Location>s now treat a slash as a special
6834 character. For example "/home/*/public_html" previously would
6835 match "/home/a/andrew/public_html", now it only matches things
6836 like "/home/bob/public_html". This mimics /bin/sh behaviour.
6837 - It's possible now to use [] wildcarding in <Directory>, <Files>
6839 - Regex <Directory>s are applied after all non-regex <Directory>s.
6843 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
6844 and corrupted paths. [Dean Gaudet]
6846 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
6847 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
6848 be accessed now via backreferences $1..$9 in RewriteConds test-against
6849 strings in addition to RewriteRules subst string. Second the grouped
6850 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
6851 via backreferences %1..%9 both in following RewriteCond test-against
6852 strings and RewriteRules subst string. This provides maximum flexibility
6853 through the use of backreferences.
6854 Additionally the rewriting engine was cleaned up by putting common
6855 code to the new expand_backrefs_inbuffer() function.
6856 [Ralf S. Engelschall]
6858 *) When merging the main server's <Directory> and <Location> sections into
6859 a vhost, put the main server's first and the vhost's second. Otherwise
6860 the vhost can't override the main server. [Dean Gaudet] PR#717
6862 *) The <Directory> code would merge and re-merge the same section after
6863 a match was found, possibly causing problems with some modules.
6866 *) ip-based vhosts are stored and queried using a hashing function, which
6867 has been shown to improve performance on servers with many ip-vhosts.
6868 Some other changes had to be made to accommodate this:
6869 - the * address for vhosts now behaves like _default_
6870 - the matching process now is:
6871 - match an ip-vhost directly via hash (possibly matches main
6873 - if that fails, just pretend it matched the main server
6874 - if so far only the main server has been matched, perform
6875 name-based lookups (ServerName, ServerAlias, ServerPath)
6876 *only on name-based vhosts*
6877 - if they fail, look for _default_ vhosts
6878 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
6880 *) dbmmanage overhaul:
6881 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
6882 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
6883 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
6884 - provide better seed for rand
6885 - prompt for password as per getpass(3) (turn off echo, read from
6887 - use "newstyle" crypt based on $Config{osname} ($^O)
6888 - will not add a user if already in database, use new `update' command
6890 - added `check' command to check a users' password
6891 - added `import' command to convert existing password text-files or
6892 dbm files exported with `view'
6893 - more descriptive usage, general cleanup, 'use strict' clean, etc.
6896 *) Added psocket() which is a pool form of socket(), various places within
6897 the proxy weren't properly blocking alarms while registering the cleanup
6898 for its sockets. bclose() now uses pclose() and pclosesocket(). There
6899 was a bug where the client socket was being close()d twice due a still
6900 registered cleanup. [Dean Gaudet]
6902 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
6905 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
6906 [Jason Venner <jason@idiom.com>] PR#667
6908 *) Enable ``=""'' for RewriteCond directives to match against
6909 the empty string. This is the preferred way instead of ``^$''.
6910 [Ralf S. Engelschall]
6912 *) Fixed an infinite loop in mod_imap for references above the server root
6913 [Dean Gaudet] PR#748
6915 *) mod_proxy now has a ReceiveBufferSize directive, similar to
6916 SendBufferSize, so that the TCP window can be set appropriately
6917 for LFNs. [Phillip A. Prindeville]
6919 *) mod_browser has been replaced by the more general mod_setenvif
6920 (courtesy of Paul Sutton). BrowserMatch* directives are still
6921 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
6922 UnSetEnvIfZero directives. [Ken Coar]
6924 *) "HostnameLookups double" forces double-reverse DNS to succeed in
6925 order for remote_host to be set (for logging, or for the env var
6926 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
6929 *) mod_access overhaul:
6930 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
6931 and cidr syntax (i.e. 10.1.0.0/16). PR#762
6932 - Critical path was sped up by pre-computing a few things at config time.
6933 - The undocumented syntax "allow user-agents" was removed,
6934 the replacement is "allow from env=foobar" combined with mod_browser.
6935 - When used with hostnames it now forces a double-reverse lookup
6936 no matter what the directory settings are. This double-reverse
6937 doesn't affect any of the other routines that use the remote
6938 hostname. In particular it's still passed to CGIs and the log
6939 without the double-reverse check. Related PR#860.
6942 *) When a large bwrite() occurs (larger than the internal buffer size),
6943 while there is already something in the buffer, apache will combine
6944 the large write and the buffer into a single writev(). (This is
6945 in anticipation of using mmap() for reading files.)
6948 *) In obscure cases where a partial socket write occurred while chunking,
6949 Apache would omit the chunk header/footer on the next block. Cleaned
6950 up other bugs/inconsistencies in error conditions in buff.c. Fixed
6951 a bug where a long pause in DNS lookups could cause the last packet
6952 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
6954 *) API: Added child_exit function to module structure. This is called
6955 once per "heavy-weight process" just before a server child exit()'s
6956 e.g. when max_requests_per_child is reached, etc.
6957 [Doug MacEachern, Dean Gaudet]
6959 *) mod_include cleanup showed that handle_else was being used to handle
6960 endif. It didn't cause problems, but it was cleaned up too.
6963 *) mod_cern_meta would attempt to find meta files for the directory itself
6964 in some cases, but not in others. It now avoids it in all cases.
6967 *) mod_mime_magic would core dump if there was a decompression error.
6968 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
6970 *) PORT: some variants of DGUX require -lsocket -lnsl
6971 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
6973 *) mod_autoindex now allows sorting of FancyIndexed directory listings
6974 by the various fields (name, size, et cetera), either in ascending
6975 or descending order. Just click on the column header. [Ken Coar]
6977 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
6978 CPUs like the Alpha. Apache still stores ints in pointers, but that's
6979 the relatively safe direction. [Dean Gaudet] PR#344
6981 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
6982 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
6984 *) child_main avoids an unneeded call to select() when there is only one
6985 listening socket. [Dean Gaudet]
6987 *) In the event that the server is starved for idle servers it will
6988 spawn 1, then 2, then 4, ..., then 32 servers each second,
6989 doubling each second. It'll also give a warning in the errorlog
6990 since the most common reason for this is a poor StartServers
6991 setting. The define MAX_SPAWN_RATE can be used to raise/lower
6992 the maximum. [Dean Gaudet]
6994 *) Apache now provides an effectively unbuffered connection for
6995 CGI scripts. This means that data will be sent to the client
6996 as soon as the CGI pauses or stops output; previously, Apache would
6997 buffer the output up to a fixed buffer size before sending, which
6998 could result in the user viewing an empty page until the CGI finished
6999 or output a complete buffer. It is no longer necessary to use an
7000 "nph-" CGI to get unbuffered output. Given that most CGIs are written
7001 in a language that by default does buffering (e.g. perl) this
7002 shouldn't have a detrimental effect on performance.
7004 "nph-" CGIs, which formerly provided a direct socket to the client
7005 without any server post-processing, were not fully compatible with
7006 HTTP/1.1 or SSL support. As such they would have had to implement
7007 the transport details, such as encryption or chunking, in order
7008 to work properly in certain situations. Now, the only difference
7009 between nph and non-nph scripts is "non-parsed headers".
7010 [Dean Gaudet, Sameer Parekh, Roy Fielding]
7012 *) If a BUFF is switched from buffered to unbuffered reading the first
7013 bread() will return whatever remained in the buffer prior to the
7014 switch. [Dean Gaudet]
7016 Changes with Apache 1.3a1
7018 *) Added another Configure helper script: TestLib. It determines
7019 if a specified library exists. [Jim Jagielski]
7021 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
7022 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
7025 *) PORT: Some architectures use size_t for various lengths in network
7026 functions such as accept(), and getsockname(). The definition
7027 NET_SIZE_T is used to control this. [Dean Gaudet]
7029 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
7030 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
7031 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
7033 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
7034 [Igor N Kovalenko <infoh@mail.wplus.net>]
7036 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7037 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7038 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
7039 [Dean Gaudet] related PR#875
7041 *) API: Correct child_init() slot declaration from int to void, to
7042 match the init() declaration. Update mod_example to use the new
7045 *) added transport handle slot (t_handle) to the BUFF structure
7048 *) get_client_block() returns wrong length if policy is
7049 REQUEST_CHUNKED_DECHUNK.

7056 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
7057 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
7059 *) AddModuleInfo directive for mod_info which allows you to annotate
7060 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
7062 *) Added NoProxy directive to avoid using ProxyRemote for selected
7063 addresses. Added ProxyDomain directive to cause unqualified
7064 names to be qualified by redirection.
7065 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
7067 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
7068 header to the remote host in the proxy. [Sameer Parekh and
7071 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
7072 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
7073 URLs, fixed rewritelog(), fixed forced response code handling on
7074 redirects from within .htaccess files, disabled pipe locking under
7075 braindead SunOS 4.1.x, allow env variables to be set even on rules with
7076 no substitution, bugfixed situations where HostnameLookups is off, made
7077 mod_rewrite more thread-safe for NT port and fixed problem when creating
7078 an empty query string via "xxx?".
7079 This update also removes the copyright of Ralf S. Engelschall,
7080 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
7081 exclusively copyrighted by the Apache Group now. This happened because
7082 the author now has gifted mod_rewrite exclusively to the Apache Group and
7083 no longer maintains an external version.
7084 [Ralf S. Engelschall]
7086 *) API: Added child_init function to module structure. This is called
7087 once per "heavy-weight process" before any requests are handled.
7088 See http_config.h for more details. [Dean Gaudet]
7090 *) Anonymous_LogEmail was logging on each subrequest.
7091 [Dean Gaudet] PR#421, 868
7093 *) API: Added is_initial_req() which tests if the request being
7094 processed is the initial request, or a subrequest.
7097 *) Extended SSI (mod_include) now handles additional relops for
7098 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
7100 *) Configure fixed to correctly propagate user-selected options and
7101 settings (such as CC and OPTIM) to Makefiles other than
7102 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
7104 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
7105 directory indices to start with the contents of the HeaderName file
7106 if there is one. If there isn't one, the behaviour is unchanged.
7107 [Ken Coar, Roy Fielding, Andrey A. Chernov]
7109 *) WIN32: Modules can now be dynamically loaded DLLs using the
7110 LoadModule/LoadFile directives. Note that module DLLs must be
7111 compiled with the multithreaded DLL version of the runtime library.
7112 [Alexei Kosut and Ben Laurie]
7114 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
7115 This allows the admin to completely remove automatic indexing
7116 from the server, while still supporting the basic functions of
7117 trailing-slash redirects and DirectoryIndex files. Note that if
7118 you're carrying over an old Configuration file and you use directory
7119 indexing then you'll want to add:
7121 Module autoindex_module mod_autoindex.o
7123 before mod_dir in your Configuration. [Dean Gaudet]
7125 *) popendir/pclosedir created to properly protect directory scanning.
7126 [Dean Gaudet] PR#525
7128 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
7129 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
7130 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
7133 *) The AccessFileName directive can now take more than one filename.
7134 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
7136 *) The new mod_mime_magic can be used to "magically" determine the type
7137 of a file if the extension is unknown. Based on the unix file(1)
7138 command. [Ian Kluft <ikluft@cisco.com>]
7140 *) We now determine and display the time spent processing a
7141 request if desired. [Jim Jagielski]
7143 *) mod_status: PID field of "dead" child slots no longer displays
7144 main httpd process's PID. [Jim Jagielski]
7146 *) Makefile.nt added - to build all the bits from the command line:
7147 nmake -f Makefile.nt
7148 Doesn't yet work properly. [Ben Laurie]
7150 *) Default text of 404 error is now "Not Found" rather than the
7151 potentially misleading "File Not Found". [Ken Coar]
7153 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
7154 for the net if we require people that actually need this data to
7155 enable it. [Linus Torvalds]
7157 *) directory_walk() is an expensive function, keep a little more state to
7158 avoid needless string counting. Add two new functions make_dirstr_parent
7159 and make_dirstr_prefix which replace all existing uses of make_dirstr.
7160 The new functions are a little less general than make_dirstr, but
7161 work more efficiently (less memory, less string counting).
7164 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
7165 to LDFLAGS) to avoid complications with lex rules in make files.
7166 [Dean Gaudet] PR#372
7168 *) run_method optimized to avoid needless scanning over NULLs in the
7169 module list. [Dean Gaudet]
7171 *) Revamp of (unix) scoreboard management code such that it avoids
7172 unnecessary traversals of the scoreboard on each hit. This is
7173 particularly important for high volume sites with a large
7174 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
7175 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
7176 httpd.h. [Dean Gaudet]
7178 *) In configurations using multiple Listen statements it was possible for
7179 busy sockets to starve other sockets of service. [Dean Gaudet]
7181 *) Added hook so standalone_main can be replaced at compile time
7182 (define STANDALONE_MAIN)
7185 *) Lowest-level read/write functions in buff.c will be replaced with
7186 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
7187 compile time. The default sfio discipline will behave as apache
7188 would without sfio compiled in.
7191 *) Enhance UserDir directive (mod_userdir) to accept a list of
7192 usernames for the 'disable' keyword, and add 'enable user...' to
7193 selectively *en*able userdirs if they're globally disabled.
7196 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
7197 will work with Netscape dbm files. (dbmmanage will probably not
7198 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
7200 *) Add a ListenBacklog directive to control the backlog parameter
7201 passed to listen(). Also change the default to 511 from 512.
7204 *) API: A new handler response DONE which informs apache that the
7205 request has been handled and it can finish off quickly, similar to
7206 how it handles errors. [Rob Hartill]
7208 *) Turn off chunked encoding after sending terminating chunk/footer
7209 so that we can't do it twice by accident. [Roy Fielding]
7211 *) mod_expire also issues Cache-Control: max-age headers.
7214 *) API: Added kill_only_once option for free_proc_chain so that it won't
7215 aggressively try to kill off specific children. For fastcgi.
7216 [Stanley Gambarin <gambarin@OpenMarket.com>]
7218 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
7220 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
7221 When used together, these cause mod_dir to emit HEIGHT and WIDTH
7222 attributes in the FancyIndexing IMG tags. [Ken Coar]
7224 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
7226 *) PORT: Added Windows NT support
7227 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
7229 Changes with Apache 1.2.6
7231 *) mod_include when using XBitHack Full would send ETags in addition to
7232 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
7233 [Dean Gaudet] PR#1133
7235 *) SECURITY: When a client connects to a particular port/addr, and
7236 gives a Host: header ensure that the virtual host requested can
7237 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
7239 *) Support virtual hosts with wildcard port and/or multiple ports
7240 properly. [Ed Korthof <ed@organic.com>]
7242 *) Fixed some case-sensitivity issues according to RFC2068.
7245 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
7246 and mod_include.c. [Dean Gaudet]
7248 *) Variable 'cwd' was being used pointlessly before being set.
7251 *) SIGURG doesn't exist on all platforms.
7252 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
7254 *) When an error occurs during a POST, or other operation with a
7255 request body, the body has to be read from the net before allowing
7256 a keepalive session to continue. [Roy Fielding] PR#1399
7258 *) When an error occurs in fcntl() locking suggest the user look up
7259 the docs for LockFile. [Dean Gaudet]
7261 *) table_set() and table_unset() did not deal correctly with
7262 multiple occurrences of the same key. [Stephen Scheck
7263 <sscheck@infonex.net>, Ben Laurie] PR#1604
7265 *) send_fd_length() did not calculate total_bytes_sent properly in error
7266 cases. [Ben Reser <breser@regnow.com>] PR#1366
7268 *) r->connection->user was allocated in the wrong pool causing corruption
7269 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
7271 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7272 Also removed the auto-generated link to www.apache.org that was the
7273 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7275 *) Multiple "close" tokens may have been set in the "Connection"
7276 header, not an error, but a waste.
7277 [Ronald.Tschalaer@psi.ch] PR#1683
7279 *) "basic" and "digest" auth tokens should be tested case-insensitive.
7280 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
7282 *) It appears the "257th byte" bug (see
7283 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
7284 at the 256th byte as well. Fixed. [Dean Gaudet]
7286 *) mod_rewrite would not handle %3f properly in some situations.
7289 *) Apache could generate improperly chunked HTTP/1.1 responses when
7290 the bputc() or rputc() functions were used by modules (such as
7291 mod_include). [Dean Gaudet]
7293 *) #ifdef wrap a few #defines in httpd.h to make life easier on
7294 some ports. [Ralf Engelschall]
7296 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
7298 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
7300 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
7302 Changes with Apache 1.2.5
7304 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
7305 only an issue on systems without a MAXDNAME define or where
7306 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
7308 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
7311 *) Fix core dump in the ftp proxy when reading incorrectly formatted
7312 directory listings. [Marc Slemko]
7314 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
7317 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
7318 is used to read various types of files such as htaccess and
7319 htpasswd files. [Marc Slemko]
7321 *) SECURITY: Ensure that the buffer returned by ht_time is always
7322 properly null terminated. [Marc Slemko]
7324 *) SECURITY: General mod_include cleanup, including fixing several
7325 possible buffer overflows and a possible infinite loop. This cleanup
7326 was done against 1.3 code and then backported to 1.2, the result
7327 is a large difference (due to indentation cleanup in 1.3 code).
7328 Users interested in seeing a smaller set of relevant differences
7329 should consider comparing against src/modules/standard/mod_include.c
7330 from the 1.3b3 release. Non-indentation changes to mod_include
7331 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
7333 *) SECURITY: Numerous changes to mod_imap in a general cleanup
7334 including fixing a possible buffer overflow. This cleanup also
7335 was done with 1.3 code as a basis, see the the previous note
7336 about mod_include. [Dean Gaudet]
7338 *) SECURITY: If a htaccess file can not be read due to bad
7339 permissions, deny access to the directory with a HTTP_FORBIDDEN.
7340 The previous behavior was to ignore the htaccess file if it could not
7341 be read. This change may make some setups with unreadable
7342 htaccess files stop working. PR#817 [Marc Slemko]
7344 *) SECURITY: no2slash() was O(n^2) in the length of the input.
7345 Make it O(n). This inefficiency could be used to mount a denial
7346 of service attack against the Apache server. Thanks to
7347 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting

7356 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7358 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7359 r->filename. Since those two are meant to be in sync with each other
7360 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
7362 *) mod_include did not properly handle all possible redirects from sub-

7365 *) Inetd mode (which is buggy) uses timeouts without having setup the
7366 jmpbuffer. [Dean Gaudet] PR#1064
7368 *) Work around problem under Linux where a child will start looping
7369 reporting a select error over and over.
7370 [Rick Franchuk <rickf@transpect.net>] PR#1107
7372 Changes with Apache 1.2.4
7374 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
7375 always making requests with the full-URI instead of just the URI path.
7376 [Marc Slemko, Roy Fielding]
7378 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
7379 on this platform. [Marc Slemko]
7381 Changes with Apache 1.2.3
7383 *) The request to a remote proxy was mangled if it was generated as the
7384 result of a ProxyPass directive. URL schemes other than http:// were not
7385 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,

7388 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7389 information for case where proxy module is not available. [Marc Slemko]
7391 *) Force proxy to always respond as HTTP/1.0, which it was failing to
7392 do for errors and cached responses. [Roy Fielding]
7394 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
7396 Changes with Apache 1.2.2 [not released]
7398 *) Fixed another long-standing bug in sub_req_lookup_file where it would
7399 happily skip past access checks on subdirectories looked up with relative
7400 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
7403 *) Add lockfile name to error message printed out when
7404 USE_FLOCK_SERIALIZED_ACCEPT is defined.
7407 *) Enhanced the chunking and error handling inside the buffer functions.
7408 [Dean Gaudet, Roy Fielding]

7411 a vhost, put the main server's first and the vhost's second. Otherwise
7412 the vhost can't override the main server. [Dean Gaudet] PR#717
7414 *) The <Directory> code would merge and re-merge the same section after
7415 a match was found, possibly causing problems with some modules.
7418 *) Fixed an infinite loop in mod_imap for references above the server root.
7419 [Dean Gaudet] PR#748
7421 *) mod_include cleanup showed that handle_else was being used to handle
7422 endif. It didn't cause problems, but it was cleaned up too.
7425 *) Last official synchronization of mod_rewrite with author version (because
7426 mod_rewrite is now directly developed by the author at the Apache Group):
7427 o added diff between mod_rewrite 3.0.6+ and 3.0.9
7428 minus WIN32/NT stuff, but plus copyright removement.
7430 - workaround for detecting infinite rewriting loops
7431 - fixed setting of env vars when "-" is used as subst string

7437 o remove static from local data and add static to global ones.
7438 o replaced ugly proxy finding stuff by simple
7439 find_linked_module("mod_proxy") call.

7447 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7448 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7449 "downgrade-1.0" which causes Apache to pretend it received a 1.0.

7451 a deficiency in the header_parse phase.

7469 under Solaris 2.x (up through 2.5.1). It has been fixed.
7470 [Dean Gaudet] PR#832
7472 *) API: In HTTP/1.1, whether or not a request message contains a body
7473 is independent of the request method and based solely on the presence
7474 of a Content-Length or Transfer-Encoding. Therefore, our default
7475 handlers need to be prepared to read a body even if they don't know
7476 what to do with it; otherwise, the body would be mistaken for the
7477 next request on a persistent connection. discard_request_body()
7478 has been added to take care of that. [Roy Fielding] PR#378
7480 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
7481 release version number, such that it always increases along the
7482 same lines as our source code branching. [Roy Fielding]
7484 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
7486 Changes with Apache 1.2.1
7488 *) SECURITY: Don't serve file system objects unless they are plain files,
7489 symlinks, or directories. This prevents local users from using pipes
7490 or named sockets to invoke programs for an extremely crude form of
7493 *) SECURITY: HeaderName and ReadmeName were settable in .htaccess and
7494 could contain "../" allowing a local user to "publish" any file on
7495 the system. No slashes are allowed now. [Dean Gaudet]
7497 *) SECURITY: It was possible to violate the symlink Options using mod_dir
7498 (headers, readmes, titles), mod_negotiation (type maps), or
7499 mod_cern_meta (meta files). [Dean Gaudet]
7501 *) SECURITY: Apache will refuse to run as "User root" unless
7502 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
7504 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
7505 if it contained a .htaccess disallowing symlinks. This is contrary
7506 to the rule that symlink permissions are tested with the symlink
7507 options of the parent directory. [Dean Gaudet] PR#353
7509 *) CONFIG: The LockFile directive can be used to place the serializing
7510 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
7511 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
7514 *) Request processing now retains state of whether or not the request
7515 body has been read, so that internal redirects and subrequests will
7516 not try to read it twice (and block). [Roy Fielding]
7518 *) Add a placeholder in modules/Makefile to avoid errors with certain
7519 makes. [Marc Slemko]
7521 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.
7522 [Dean Gaudet] PR#644
7524 *) mod_include was not properly changing the current directory.
7525 [Marc Slemko] PR#742
7527 *) Attempt to work around problems with third party libraries that do not
7528 handle high numbered descriptors (examples include bind, and
7529 solaris libc). On all systems apache attempts to keep all permanent
7530 descriptors above 15 (called the low slack line). Solaris users
7531 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
7532 which keeps all non-FILE * descriptors above 255. On all systems
7533 this should make supporting large numbers of vhosts with many open
7534 log files more feasible. If this causes trouble please report it,
7535 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
7536 [Dean Gaudet] various PRs
7538 *) Related to the last entry, network sockets are now opened before
7539 log files are opened. The only known case where this can cause
7540 problems is under Solaris with many virtualhosts and many Listen
7541 directives. But using -DHIGH_SLACK_LINE=256 described above will
7542 work around this problem. [Dean Gaudet]
7544 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and

7597 reading from one buffer and writing to another, at least until it has
7598 a custom timeout handler. [Roy Fielding and Petr Lampa]

7608 *) Virtual hosts with the same ServerName, but on different ports, were
7609 not being selected properly. [Ed Korthof]
7611 *) Added code to return the requested IP address from proxy_host2addr()

7613 change submitted by Jozsef Hollosi <hollosi@sbcm.com>.
7614 [Chuck Murcko] PR#614
7616 *) If multiple requests on a single connection are used to retrieve
7617 data from different virtual hosts, the virtual host list would be
7618 scanned starting with the most recently used VH instead of the first,
7619 causing most virtual hosts to be ignored.

7629 has found matching variants, but none are acceptable, return the

7633 *) If a soft_timeout occurs after keepalive is set, then the main child
7634 loop would try to read another request even though the connection
7635 has been aborted. [Roy Fielding]
7637 *) Configure changes: Allow for whitespace at the start of a
7638 Module declaration. Also, be more understanding about the
7639 CC=/OPTIM= format in Configuration. Finally, fix compiler
7640 flags if using HP-UX's cc compiler. [Jim Jagielski]
7642 *) Subrequests and internal redirects now inherit the_request from the
7643 original request-line. [Roy Fielding]
7645 *) Test for error conditions before creating output header fields, since
7646 we don't want the error message to include those fields. Likewise,
7647 reset the content_language(s) and content_encoding of the response
7648 before generating or redirecting to an error message, since the new
7649 message will have its own Content-* definitions. [Dean Gaudet]
7651 *) Restored the semantics of headers_out (headers sent only with 200..299
7652 and 304 responses) and err_headers_out (headers sent with all responses).
7653 Avoid the overhead of copying tables if err_headers_out is empty
7654 (the usual case). [Roy Fielding]
7656 *) Fixed a couple places where a check for the default Content-Type was
7657 not properly checking both the value configured by the DefaultType
7658 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
7659 of DEFAULT_TYPE to match the documented default (text/plain).

7662 *) Escape the HTML-sensitive characters in the Request-URI that is
7663 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
7665 *) Properly initialize the flock structures used by the mutex locking
7666 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
7669 *) The method for determining PATH_INFO has been restored to the pre-1.2b
7670 (and NCSA httpd) definition wherein it was the extra path info beyond
7671 the CGI script filename. The environment variable FILEPATH_INFO has
7672 been removed, and instead we supply the original REQUEST_URI to any
7673 script that wants to be Apache-specific and needs the real URI path.
7674 This solves a problem with existing scripts that use extra path info
7675 in the ScriptAlias directive to pass options to the CGI script.
7678 *) The _default_ change in 1.2b10 will change the behaviour on configs
7679 that use multiple Listen statements for listening on multiple ports.
7680 But that change is necessary to make _default_ consistent with other
7681 forms of <VirtualHost>. It requires such configs to be modified
7682 to use <VirtualHost _default_:*>. The documentation has been
7683 updated. [Dean Gaudet] PR#530
7685 *) If an ErrorDocument CGI script is used to respond to an error
7686 generated by another CGI script which has already read the message
7687 body of the request, the server would block trying to read the
7688 message body again. [Rob Hartill]
7690 *) signal() replacement conflicted with a define on QNX (and potentially
7691 other platforms). Fixed. [Ben Laurie] PR#512
7693 Changes with Apache 1.2b10
7695 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
7696 to be configured via -D in Configuration. [Dean Gaudet] PR#449

7707 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
7709 Changes with Apache 1.2b9 [never announced]
7711 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
7712 changes and in anticipation of 1.2 final release. [Roy Fielding]
7714 *) Fix problem with scripts not receiving a SIGPIPE when client drops
7715 the connection (e.g., when user presses Stop). Apache will now stop
7716 trying to send a message body immediately after an error from write.
7717 [Roy Fielding and Nathan Kurz] PR#335
7719 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
7720 than mod_alias, and mod_alias has higher priority than mod_proxy;
7721 rearranged other modules to enhance understanding of their purpose
7722 and relative order (and maybe even reduce some overhead).
7723 [Roy Fielding and Sameer Parekh]
7725 *) Fix graceful restart. Eliminate many signal-related race
7726 conditions in both forms of restart, and in SIGTERM. See
7727 htdocs/manual/stopping.html for details on stopping and
7728 restarting the parent. [Dean Gaudet]
7730 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
7731 memory allocator to avoid a behaviour that required extra blocks to
7732 be allocated. [Dean Gaudet]
7734 *) Allow suexec to access files relative to current directory but not
7735 above. (Excluding leading / or any .. directory.) [Ken Coar]
7738 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
7739 PR#367, 368, 354, 453
7741 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
7742 while obtaining the /~user and save the username in a separate data
7743 area so that it won't be overwritten by the call to getgrgid(), and
7744 fix some misuse of the pool string allocation functions. Also fixes
7745 a general problem with parsing URL query info into args for CGI scripts.

7753 AuthDBAuthoritative. [Marc Slemko] PR#420
7755 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
7757 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
7758 object that can't be PUT, or FOOBAR for some method FOOBAR that
7759 apache doesn't know about at all). Log 404s that occur in mod_include.
7760 [Paul Sutton, John Van Essen]
7762 *) If a soft timeout (or lingerout) occurs while trying to flush a
7763 buffer or write inside buff.c or fread'ing from a CGI's output,
7764 then the timeout would be ignored. [Roy Fielding] PR#373
7766 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
7767 parsing of headers. If the terminating empty-line CRLF occurs starting
7768 at the 256th or 257th byte of output, then Navigator will think a normal
7769 image is invalid. We are guessing that this is because their initial
7770 read of a new request uses a 256 byte buffer. We check the bytes written
7771 so far and, if we are about to tickle the bug, we instead insert a
7772 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
7774 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
7775 of an external redirection. [Roy Fielding and Paul Sutton]
7777 *) Configure would create a broken Makefile if the configuration file
7778 contained a commented-out Rule. [Roy Fielding]
7780 *) Promote per_dir_config and subprocess_env from the subrequest to the
7781 main request in mod_negotiation. In particular this fixes a bug
7782 where <Files> sections wouldn't properly apply to negotiated content.
7785 *) Fix a potential deadlock in mod_cgi script_err handling.
7786 [Ralf S. Engelschall]
7788 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
7791 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
7792 .htaccess files because the RewriteBase was not replaced correctly.
7793 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
7794 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
7796 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
7797 1.x the settings are those of pre-1.2b8. For 2.x we include
7798 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
7799 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
7800 [Dean Gaudet] PR#336, PR#340
7802 *) Redirect did not preserve ?query_strings when present in the client's
7803 request. [Dean Gaudet]
7805 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
7807 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
7809 *) Add UnixWare compile/install instructions. [Chuck Murcko]
7811 *) Add mod_example (illustration of API techniques). [Ken Coar]
7813 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
7815 *) Improve handling of directories when filenames have spaces in them.
7818 *) For hosts with multiple IP addresses, try all additional addresses if
7819 necessary to get a connect. Fail only if hostent address list is
7820 exhausted. [Chuck Murcko]
7822 *) More signed/unsigned port fixes. [Dean Gaudet]
7824 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
7827 Changes with Apache 1.2b8
7829 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
7830 to it. [Marc Slemko]
7832 *) The addition of <Location> and <File> directives made the
7833 sub_req_lookup_simple() function bogus, so we now handle
7834 the special cases directly. [Dean Gaudet]
7836 *) We now try to log where the server is dumping core when a fatal
7837 signal is received. [Ken Coar]
7839 *) Improved lingering_close by adding a special timeout, removing the
7840 spurious log messages, removing the nonblocking settings (they
7841 are not needed with the better timeout), and adding commentary
7842 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
7843 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
7845 *) Send error messages about setsockopt failures to the server error
7846 log instead of stderr. [Roy Fielding]
7848 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
7850 *) Stopgap solution for CGI 3-second delay with server-side includes: if
7851 processing a subrequest, allocate memory from r->main->pool instead
7852 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
7853 in the middle of an SSI request. [Dean Gaudet] PR #122
7855 *) Fixed status of response when POST is received for a nonexistent URL
7856 (was sending 405, now 404) and when any method is sent with a
7857 full-URI that doesn't match the server and the server is not acting
7858 as a proxy (was sending 501, now 403). [Roy Fielding]
7860 *) Host port changed to unsigned short. [Ken Coar] PR #276
7862 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
7864 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
7866 *) Report extra info from errno with many errors that cause httpd to exit.
7867 spawn_child, popenf, and pclosef now have valid errno returns in the
7868 event of an error. Correct problems where errno was stomped on
7869 before being reported. [Dean Gaudet]
7871 *) In the proxy, if the cache filesystem was full, garbage_coll() was
7872 never called, and thus the filesystem would remain full indefinitely.
7873 We now also remove incomplete cache files left if the origin server
7874 didn't send a Content-Length header and either the client has aborted
7875 transfer or bwrite() to client has failed. [Petr Lampa]
7877 *) Fixed the handling of module and script-added header fields.
7878 Improved the interface for sending header fields and reduced
7879 the duplication of code between sending okay responses and errors.
7880 We now always send both headers_out and err_headers_out, and
7881 ensure that the server-reserved fields are not being overridden,
7882 while not overriding those that are not reserved. [Roy Fielding]
7884 *) Moved transparent content negotiation fields to err_headers_out
7885 to reflect above changes. [Petr Lampa]
7887 *) Fixed the determination of whether or not we should make the
7888 connection persistent for all of the cases where some other part
7889 of the server has already indicated that we should not. Also
7890 improved the ordering of the test so that chunked encoding will
7891 be set whenever it is desired instead of only when KeepAlive
7892 is enabled. Added persistent connection capability for most error
7893 responses (those that do not indicate a bad input stream) when
7894 accessed by an HTTP/1.1 client. [Roy Fielding]
7896 *) Added missing timeouts for sending header fields, error responses,
7897 and the last chunk of chunked encoding, each of which could have
7898 resulted in a process being stuck in write forever. Using soft_timeout
7899 requires that the sender check for an aborted connection rather than
7900 continuing after an EINTR. Timeouts that used to be initiated before
7901 send_http_header (and never killed) are now initiated only within or
7902 around the routines that actually do the sending, and not allowed to
7903 propagate above the caller. [Roy Fielding]
7905 *) mod_auth_anon required an @ or a . in the email address, not both.
7908 *) per_dir_defaults weren't set correctly until directory_walk for
7909 name-based vhosts. This fixes an obscure bug with the wrong config
7910 info being used for vhosts that share the same ip as the server.
7913 *) Improved generation of modules/Makefile to be more generic for
7914 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
7916 *) Generate makefile dependency for Configuration based on the actual
7917 name given when running the Configure process. [Dean Gaudet]
7919 *) Fixed problem with vhost error log not being set prior to
7920 initializing virtual hosts. [Dean Gaudet]
7922 *) Fixed infinite loop when a trailing slash is included after a type map
7923 file URL (extra path info). [Petr Lampa]
7925 *) Fixed server status updating of per-connection counters. [Roy Fielding]
7927 *) Add documentation for DNS issues (reliability and security), and try
7928 to explain the virtual host matching process. [Dean Gaudet]
7930 *) Try to continue gracefully by disabling the vhost if a DNS lookup
7931 fails while parsing the configuration file. [Dean Gaudet]
7933 *) Improved calls to setsockopt. [Roy Fielding]
7935 *) Negotiation changes: Don't output empty content-type in variant list;
7936 Output charset in variant list; Return sooner from handle_multi() if
7937 no variants found; Add handling of '*' wildcard in Accept-Charset.
7938 [Petr Lampa and Paul Sutton]
7940 *) Fixed overlaying of request/sub-request notes and headers in
7941 mod_negotiation. [Dean Gaudet]
7943 *) If two variants' charset quality are equal and one is the default
7944 charset (iso-8859-1), then prefer the variant that was specifically
7945 listed in Accept-Charset instead of the default. [Petr Lampa]
7947 *) Memory allocation problem in push_array() -- it would corrupt memory
7948 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
7950 *) invoke_handler() doesn't handle mime arguments in content-type
7953 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
7956 *) Fixed problem with ErrorDocument not working for virtual hosts
7957 due to one of the performance changes in 1.2b7. [Dean Gaudet]
7959 *) Log an error message if we get a request header that is too long,
7960 since it may indicate a buffer overflow attack. [Marc Slemko]
7962 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
7963 not reject URLs without a double-slash, as per RFC2068 section 3.2.
7964 [Ken Coar] PR #146, #187
7966 *) Added table entry placeholder for new header_parser callback
7967 in all of the distributed modules. [Ken Coar] PR #191
7969 *) Allow for cgi files without the .EXE extension on them under OS/2.
7970 [Garey Smiley] PR #59
7972 *) Fixed error message when resource is not found and URL contains
7973 path info. [Petr Lampa and Dean Gaudet] PR #40
7975 *) Fixed user and server confusion over what should be a virtual host
7976 and what is the main server, resulting in access to something
7977 other than the name defined in the virtualhost directive (but
7978 with the same IP address) failing. [Dean Gaudet]
7980 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
7981 AIX; improves the redirection stuff to enable the users to generally
7982 redirect to http, https, gopher and ftp; added TIME variable for
7983 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
7984 special patterns >STRING, <STRING and =STRING to RewriteCond, which
7985 can be used in conjunction with %{TIME} or other variables to create
7986 time-dependent rewriting rules. [Ralf S. Engelschall]
7988 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
7989 Module authors may need to adjust their code for proper cleanup to take
7990 place (that is, call note_cleanups_for_fd()). This change fixes problems
7991 with file descriptors being erroneously closed when the proxy module was
7992 in use. [Ben Laurie]
7994 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
7995 initgroups() to hose the group information needed for later
7996 comparisons. [Randy Terbush]
7998 *) Remove unnecessary call to va_end() in create_argv() which
7999 caused a SEGV on some systems.
8001 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
8004 *) Clear memory allocated for listeners. [Randy Terbush]
8006 *) Improved handling of IP address as a virtualhost address and
8007 introduced "_default_" as a synonym for the default vhost config.
8008 [Dean Gaudet] PR #212
8010 Changes with Apache 1.2b7
8012 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
8014 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
8016 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
8017 - replace protocol response numbers with symbols
8018 - save variant-list into main request notes
8019 - free allocated memory from subrequests
8020 - merge notes, headers_out and err_headers_out
8022 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
8023 "HTTP/#.# ###*" to be more lenient about what we accept.
8026 *) more proxy FTP bug fixes:
8027 - Changed send_dir() to remove user/passwd from displayed URL.
8028 - Changed login error messages to be more descriptive.
8029 - remove setting of SO_DEBUG socket option
8030 - Make ftp_getrc() more lenient about multiline responses,
8031 specifically, 230 responses which don't have continuation 230-
8032 on each line). These seem to be all NT FTP servers, and while
8033 perhaps questionable, they appear to be legal by RFC 959.
8034 - Add missing kill_timeout() after transfer to user completes.
8037 *) Fixed problem where a busy server could hang when restarting
8038 after being sent a SIGHUP due to child processes not exiting.
8041 *) Modify mod_include escaping so a '\' only signifies an escaped
8042 character if the next character is one that needs
8043 escaping. [Ben Laurie]
8045 *) Eliminated possible infinite loop in mod_imap when relative URLs are
8046 used with a 'base' directive that does not have a '/' in it.
8047 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
8049 *) Reduced the default timeout from 1200 seconds to 300, and the
8050 one in the sample configfile from 400 to 300. [Marc Slemko]
8052 *) Stop vbprintf from crashing if given a NULL string pointer;
8053 print (null) instead. [Ken Coar]
8055 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
8056 [Marc Slemko and Roy Fielding]
8058 *) Fixed problem with mod_cgi-generated internal redirects trying to
8059 read the request message-body twice. [Archie Cobbs and Roy Fielding]
8061 *) Reduced timeout on lingering close, removed possibility of a blocked
8062 read causing the child to hang, and stopped logging of errors if
8063 the socket is not connected (reset by client). [Roy Fielding]
8065 *) Rearranged main child loop to remove duplication of code in
8066 select/accept and keep-alive requests, fixed several bugs regarding
8067 checking scoreboard_image for exit indication and failure to
8068 account for all success conditions and trap all error conditions,
8069 prevented multiple flushes before closing the socket; close the entire
8070 socket buffer instead of just one descriptor, prevent logging of
8071 EPROTO and ECONNABORTED on platforms where supported, and generally
8072 improved readability. [Roy Fielding]
8074 *) Extensive performance improvements. Cleaned up inefficient use of
8075 auto initializers, multiple is_matchexp calls on a static string,
8076 and excessive merging of response_code_strings. [Dean Gaudet]
8078 *) Added double-buffering to mod_include to improve performance on
8079 server-side includes. [Marc Slemko]
8081 *) Several fixes for suexec wrapper. [Randy Terbush]
8082 - Make wrapper work for files on NFS filesystem.
8083 - Fix portability problem of MAXPATHLEN.
8084 - Fix array overrun problem in clean_env().
8085 - Fix allocation of PATH environment variable
8087 *) Removed extraneous blank line is description of mod_status chars.
8090 *) Logging of errors from the call_exec routine simply went nowhere,
8091 since the logfile fd has been closed, so now we send them to stderr.
8092 [Harald T. Alvestrand]
8094 *) Fixed core dump when DocumentRoot is a CGI.
8095 [Ben Laurie, reported by geddis@tesserae.com]
8097 *) Fixed potential file descriptor leak in mod_asis; updated it and
8098 http_core to use pfopen/pfclose instead of fopen/fclose.
8099 [Randy Terbush and Roy Fielding]
8101 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
8102 as the DEC Alpha which is 64-bit but uses 32-bit ints.
8103 [Dean Gaudet and Ken Coar]
8105 *) Return a 302 response code to the client when sending a redirect
8106 due to a missing trailing '/' on a directory instead of a 301; now
8107 it is cacheable. [Markus Gyger]
8109 *) Fix condition where, if a bad directive occurs in .htaccess, and
8110 sub_request() goes first to this directory, then log_reason() will
8111 SIGSEGV because it doesn't have initialized r->per_dir_config.
8112 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
8114 *) Fix handling of lang_index in is_variant_better(). This was
8115 causing problems which resulted in the server sending the
8116 wrong language document in some cases. [Petr Lampa]
8118 *) Remove free() from clean_env() in suexec wrapper. This was nuking
8119 the clean environment on some systems.
8121 *) Tweak byteserving code (e.g. serving PDF files) to work around
8122 bugs in Netscape Navigator and Microsoft Internet Explorer.
8123 Emit Content-Length header when sending multipart/byteranges.
8126 *) Port to HI-UX/WE2. [Nick Maclaren]
8128 *) Port to HP MPE operating system for HP 3000 machines
8129 [Mark Bixby <markb@cccd.edu>]
8131 *) Fixed bug which caused a segmentation fault if only one argument
8132 given to RLimit* directives. [Ed Korthof]
8134 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
8136 *) Improved buffered output to the client by delaying the flush decision
8137 until the BUFF code is actually about to read the next request.
8138 This fixes a problem introduced in 1.2b5 with clients that send
8139 an extra CRLF after a POST request. Also improved chunked output
8140 performance by combining writes using writev() and removing as
8141 many bflush() calls as possible. NOTE: Platforms without writev()
8142 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
8143 or Configure, unless we have already done so. [Dean Gaudet]
8145 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
8147 *) Fixed mod_info output corruption bug introduced by buffer overflow
8148 fixes. [Dean Gaudet]
8150 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
8151 for the special case of a 304 response. [Paul Sutton]
8153 *) Improved handling of TRACE method by bypassing normal method handling
8154 and header parsing routines; fixed Allow response to always allow TRACE.
8157 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
8159 *) Cleaned-up some of the generated HTML. [Ken Coar]
8161 Changes with Apache 1.2b6
8163 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
8165 *) Fix typo introduced in fix for potential infinite loop around
8166 accept() in child_main(). This change caused the rev to 1.2b6.
8167 1.2b5 was never a public beta.
8169 Changes with Apache 1.2b5
8171 *) Change KeepAlive semantics (On|Off instead of a number), add
8172 MaxKeepAliveRequests directive. [Alexei Kosut]
8174 *) Various NeXT compilation patches, as well as a change in
8175 regex/regcomp.c since that file also used a NEXT define.
8178 *) Allow * to terminate the end of a directory match in mod_dir.
8179 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
8181 *) Don't call can_exec() if suexec_enabled. Calling this requires
8182 scripts executed by the suexec wrapper to be world executable, which
8183 defeats one of the advantages of running the wrapper. [Randy Terbush]
8185 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
8188 *) Migration from sprintf() to snprintf() to avoid buffer
8189 overflows. [Marc Slemko]
8191 *) Provide portable snprintf() implementation (ap_snprintf)
8192 as well as *cvt family. [Jim Jagielski]
8194 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
8197 *) Remove mod_fastcgi.c from the distribution. This module appears
8198 to be maintained more through the Open Market channels and should
8199 continue to be easily available at http://www.fastcgi.com/
8201 *) Fixed bug in modules/Makefile that wouldn't allow building in more
8202 than one subdirectory (or cleaning, either). [Jeremy Laidman]
8204 *) mod_info assumed that the config files were relative to ServerRoot.
8207 *) CGI scripts called as an error document resulting from failed
8208 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
8210 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
8213 *) Properly check errno to prevent display of a directory index
8214 when server receives a long enough URL to confuse stat().
8217 *) Several security enhancements to suexec wrapper. It is _highly_
8218 recommended that previously installed versions of the wrapper
8219 be replaced with this version. [Randy Terbush, Jason Dour]
8221 - ~user execution now properly restricted to ~user's home
8222 directory and below.
8223 - execution restricted to UID/GID > 100
8224 - restrict passed environment to known variables
8225 - call setgid() before initgroups() (portability fix)
8226 - remove use of setenv() (portability fix)
8228 *) Add HTTP/1.0 response forcing. [Ben Laurie]
8230 *) Add access control via environment variables. [Ben Laurie]
8232 *) Add rflush() function. [Alexei Kosut]
8234 *) remove duplicate pcalloc() call in new_connection().
8236 *) Fix incorrect comparison which could allow number of children =
8237 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
8238 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
8240 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
8241 AIX PS/2, CONVEXOS. [Jim Jagielski]
8243 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
8244 It's more portable. [Martin Kraemer]
8246 *) Replace references to make in Makefile.tmpl with $(MAKE).
8249 *) Add ProxyBlock directive w/IP address caching. Add IP address
8250 caching to NoCache directive as well. ProxyBlock works with all
8251 handlers; NoCache now also works with FTP for anonymous logins.
8252 Still more code cleanup. [Chuck Murcko]
8254 *) Add "header parse" API hook [Ben Laurie]
8256 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
8258 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
8260 *) Correctly allow access and auth directives in <Files> sections in
8261 server config files. [Alexei Kosut]
8263 *) Fix bug with ServerPath that could cause certain files to be not
8264 found by the server. [Alexei Kosut]
8266 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
8267 double-quote from text and so that it properly checks for unsupported
8268 status codes using the new index_of_response interface. [Roy Fielding]
8270 *) Multiple fixes to the lingering_close code in order to avoid being
8271 interrupted by a stray timeout, to avoid lingering on a connection
8272 that has already been aborted or never really existed, to ensure that
8273 we stop lingering as soon as any error condition is received, and to
8274 prevent being stuck indefinitely if the read blocks. Also improves
8275 reporting of error conditions. [Marc Slemko and Roy Fielding]
8277 *) Fixed initialization of parameter structure for sigaction.
8278 [mgyger@itr.ch, Adrian Filipi-Martin]
8280 *) Fixed reinitializing the parameters before each call to accept and
8281 select, and removed potential for infinite loop in accept.
8282 [Roy Fielding, after useful PR from adrian@virginia.edu]
8284 *) Fixed condition where, if a child fails to fork, the scoreboard would
8285 continue to say SERVER_STARTING forever. Eventually, the main process
8286 would refuse to start new children because count_idle_servers() will
8287 count those SERVER_STARTING entries and will always report that there
8288 are enough idle servers. [Phillip Vandry]
8290 *) Fixed bug in bcwrite regarding failure to account for partial writes.
8291 Avoided calling bflush() when the client is pipelining requests.
8292 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
8294 *) Added description of "." mode in server-status [Jim Jagielski]
8296 Changes with Apache 1.2b4
8298 *) Fix possible race condition in accept_mutex_init() that
8299 could leave a small security hole open allowing files to be
8300 overwritten in cases where the server UID has write permissions.
8303 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
8305 *) Fix portablity problem in util_script where ARG_MAX may not be
8306 defined for some systems.
8308 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
8311 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
8312 style magic #! token for better script portability. [Garey Smiley]
8314 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
8315 execution for ~userdir CGI. [Jason Dour]
8317 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
8319 *) Fix month off by one in suexec wrapper logging.
8321 Changes with Apache 1.2b3:
8323 *) Fix error in mod_cgi which could cause resources not to be properly
8324 freed, or worse. [Dean Gaudet]
8326 *) Fix find_string() NULL pointer dereference. [Howard Fear]
8328 *) Add set_flag_slot() at the request of Dirk and others.
8331 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
8333 *) Add changes to improve the error message given for invalid
8334 ServerName parameters. [Dirk vanGulik]
8336 *) Add "Authoritative" directive for Auth modules that don't
8337 currently have it. This gives admin control to assign authoritative
8338 control to an authentication scheme and allow "fall through" for
8339 those authentication modules that aren't "Authoritative" thereby
8340 allowing multiple authentication mechanisms to be chained.
8343 *) Remove requirement for ResourceConfig/AccessConfig if not using
8344 the three config file layout. [Randy Terbush]
8346 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
8348 *) Changes to suexec wrapper to fix the following problems:
8349 1. symlinked homedirs will kill ~userdirs.
8350 2. initgroups() on Linux 2.0.x clobbers gr->grid.
8351 3. CGI command lines paramters problems
8352 4. pw-pwdir for "docroot check" still the httpd user's pw record.
8353 [Randy Terbush, Jason Dour]
8355 *) Change create_argv() to accept variable arguments. This fixes
8356 a problem where arguments were not getting passed to the CGI via
8357 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
8359 *) Collapse multiple slashes in path URLs to properly apply
8360 handlers defined by <Location>. [Alexei Kosut]
8362 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
8364 *) Improve the accuracy of request duration timings by setting
8365 r->request_time in read_request_line() instead of read_request().
8368 *) Reset timeout while reading via get_client_block() in mod_cgi.c
8369 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
8371 *) Add the ability to pass different Makefile.tmpl files to Configure
8372 using the -make flag. [Rob Hartill]
8374 *) Fix coredump triggered when sending a SIGHUP to the server caused
8375 by an assertion failure, in turn caused by an uninitialised field in a
8379 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
8380 PATH_INFO from previous versions of Apache (in certain situations,
8381 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
8382 [later removed in 1.2b11]
8384 *) Add rwrite() function to API to allow for sending strings of
8385 arbitrary length. [Doug MacEachern]
8387 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
8389 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
8390 NeXT. [Jim Jagielski]
8392 *) Removed recent modification to promote the status code on internal
8393 redirects, since the correct fix was to change the default log format
8394 in mod_log_config so that it outputs the original status. [Rob Hartill]
8396 Changes with Apache 1.2b2:
8398 *) Update set_signals() to use sigaction() for setting handlers.
8399 This appears to fix a re-entrant problem in the seg_fault()
8400 bus_error() handlers. [Randy Terbush]
8402 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
8404 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
8406 *) proxy_http.c bugfixes: [Chuck Murcko]
8407 1) fixes possible NULL pointer reference w/NoCache
8408 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
8409 host would cache nothing if it was in the local domain,
8410 and the local domain was in the NoCache list)
8411 3) Adds Host: header when not available
8412 4) Some code cleanup and clarification
8414 *) mod_include.c bugfixes:
8415 1) Fixed an ommission that caused include variables to not
8416 be parsed in config errmsg directives [Howard Fear]
8417 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
8418 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
8419 4) Allow backslash-escaping to all quoted text
8420 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
8421 5) Pass variable to command line if not set in XSSI's env
8424 *) Fix infinite loop when processing Content-language lines in
8425 type-map files. [Alexei Kosut]
8427 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
8429 *) Fixed problem in set_[user|group] that prevented CGI execution
8430 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
8432 *) Added PORTING information file. [Jim Jagielski]
8434 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
8436 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
8438 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
8439 USE_FCNTL_SERIALIZED_ACCEPT was intended.
8441 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
8442 which caused problems of systems where socket s_addr is >32bits.
8444 *) Added comment to explain (r->chunked = 1) side-effect in
8445 http_protocol.c [Roy Fielding]
8447 *) Replaced use of index() in mod_expires.c with more appropriate
8448 and portable isdigit() test. [Ben Laurie]
8450 *) Updated Configure for ...
8451 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
8452 *-dg-dgux* (bad pattern match)
8453 QNX (DEF_WANTHSREGEX=yes)
8454 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
8457 and added some user diagnostic info. [Ben Laurie]
8459 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
8460 for better portability. [Jim Jagielski]
8462 *) Updated helpers/GuessOS for ...
8463 SCO 5 (recognize minor releases)
8464 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
8465 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
8466 IRIX64 (-sgi-irix64)
8467 ULTRIX (-unknown-ultrix)
8468 SINIX (-whatever-sysv4)
8469 NCR Unix (-ncr-sysv4)
8470 and fixed something in helpers/PrintPath [Ben Laurie]
8472 Changes with Apache 1.2b1
8474 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
8476 Changes with Apache 1.1.1
8478 *) Fixed bug where Cookie module would make two entries in the
8479 logfile for each access [Mark Cox]
8481 *) Fixed bug where Redirect in .htaccess files would cause memory
8482 leak. [Nathan Neulinger]
8484 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
8486 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
8488 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
8490 Changes with Apache 1.1.0
8492 *) Bring NeXT support up to date. [Takaaki Matsumoto]
8494 *) Bring QNX support up to date. [Ben Laurie]
8496 *) Make virtual hosts default to main server keepalive parameters.
8497 [Alexei Kosut, Ben Laurie]
8499 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
8501 *) Fix missing address family for connect, also remove unreachable statement
8502 in mod_proxy. [Ben Laurie]
8504 *) mod_env now turned on by default in Configuration.tmpl.
8506 *) Bugs which were fixed:
8507 a) yet more mod_proxy bugs [Ben Laurie]
8508 b) CGI works again with inetd [Alexei Kosut]
8509 c) Leading colons were stripped from passwords [osm@interguide.com]
8510 d) Another fix to multi-method Limit problem [jk@tools.de]
8512 Changes with Apache 1.1b4
8514 *) r->bytes_sent variable restored. [Robert Thau]
8516 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
8518 *) More possibly unsecure programs removed from the support directory.
8520 *) More mod_auth_msql authentication improvements.
8522 *) VirtualHosts based on Host: headers no longer conflict with the
8525 *) OS/2 compatibility enhancements. [Gary Smiley]
8527 *) POST now allowed to directory index CGI scripts.
8529 *) Actions now work with files of the default type.
8531 *) Bugs which were fixed:
8532 a) more mod_proxy bugs
8533 b) early termination of inetd requests
8534 c) compile warnings on several systems
8535 d) problems when scripts stop reading output early
8537 Changes with Apache 1.1b3
8539 *) Much of cgi-bin and all of cgi-src has been removed, due to
8540 various security holes found and that we could no longer support
8543 *) The "Set-Cookie" header is now special-cased to not merge multiple
8544 instances, since certain popular browsers can not handle multiple
8545 Set-Cookie instructions in a single header. [Paul Sutton]
8547 *) rprintf() added to buffer code, occurrences of sprintf removed.
8550 *) CONNECT method for proxy module, which means tunneling SSL should work.
8551 (No crypto needed) Also a NoCache config directive.
8553 *) Several API additions: pstrndup(), table_unset() and get_token()
8554 functions now available to modules.
8556 *) mod_imap fixups, in particular Location: headers are now complete
8559 *) New "info" module which reports on installed module set through a
8560 special URL, a la mod_status.
8562 *) "ServerPath" directive added - allows for graceful transition
8563 for Host:-header-based virtual hosts.
8565 *) Anonymous authentication module improvements.
8567 *) MSQL authentication module improvements.
8569 *) Status module design improved - output now table-based. [Ben Laurie]
8571 *) htdigest utility included for use with digest authentication
8574 *) mod_negotiation: Accept values with wildcards to be treated with
8575 less priority than those without wildcards at the same quality
8576 value. [Alexei Kosut]
8578 *) Bugs which were fixed:
8579 a) numerous mod_proxy bugs
8580 b) CGI early-termination bug [Ben Laurie]
8581 c) Keepalives not working with virtual hosts
8582 d) RefererIgnore problems
8583 e) closing fd's twice in mod_include (causing core dumps on
8584 Linux and elsewhere).
8586 Changes with Apache 1.1b2
8589 a) core dumps in mod_digest
8590 b) truncated hostnames/ip address in the logs
8591 c) relative URL's in mod_imap map files
8593 Changes with Apache 1.1b1
8595 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
8597 Changes with Apache 1.0.3
8599 *) Internal redirects which occur in mod_dir.c now preserve the
8600 query portion of a request (the bit after the question mark).
8603 *) Escape active characters '<', '>' and '&' in html output in
8604 directory listings, error messages and redirection links.
8607 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
8609 *) Fix for POSIX compliance in waiting for processes in alloc.c.
8612 *) setsockopt no longer takes a const declared argument [Martijn Koster]
8614 *) Reset timeout timer after each successful fwrite() to the network.
8615 This patch adds a reset_timeout() procedure that is called by
8616 send_fd() to reset the timeout ever time data is written to the net.
8619 *) timeout() signal handler now checks for SIGPIPE and reports
8620 lost connections in a more user friendly way. [Rob Hartill]
8622 *) Location of the "scoreboard" file which used to live in /tmp is
8623 now configurable (for OSes that can't use mmap) via ScoreBoardFile
8624 which works similar to PidFile (in httpd.conf) [Rob Hartill]
8626 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
8628 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
8629 which caused a SEGV with cookies enabled
8631 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
8634 *) Log the UNIX textual error returned by some system calls, in
8635 particular errors from accept() [David Robinson]
8637 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
8639 Changes with Apache 1.0.2
8641 *) patch to get Apache compiled on UnixWare 2.x, recommended as
8642 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
8644 *) Fix get_basic_auth_pw() to set the auth_type of the request.
8647 *) past changes to http_config.c to only use the
8648 setrlimit function on systems defining RLIMIT_NOFILE
8649 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
8650 for SUNOS and prototypes the needed functions.
8652 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
8655 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
8657 *) Merge multiple headers from CGI scripts instead of taking last
8658 one. [David Robinson]
8660 *) Add support for SCO 5. [Ben Laurie]
8662 Changes with Apache 1.0.1
8664 *) Silence mod_log_referer and mod_log_agent if not configured
8667 *) Recursive includes can occur if the client supplies PATH_INFO data
8668 and the server provider uses relative links; as file.html
8669 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
8671 *) The replacement for initgroups() did not call {set,end}grent(). This
8672 had two implications: if anything else used getgrent(), then
8673 initgroups() would fail, and it was consuming a file descriptor.
8676 *) On heavily loaded servers it was possible for the scoreboard to get
8677 out of sync with reality, as a result of a race condition.
8678 The observed symptoms are far more Apaches running than should
8679 be, and heavy system loads, generally followed by catastrophic
8680 system failure. [Ben Laurie]
8682 *) Fix typo in license. [David Robinson]
8684 Changes with Apache 1.0.0 23 Nov 1995
8686 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
8688 Changes with Apache 0.8.16 05 Nov 1995
8690 *) New man page for 'httpd' added to support directory [David Robinson]
8692 *) .htgroup files can have more than one line giving members for a
8693 given group (each must have the group name in front), for NCSA
8694 back-compatibility [Robert Thau]
8696 *) Mutual exclusion around accept() is on by default for SVR4 systems
8697 generally, since they generally can't handle multiple processes in
8698 accept() on the same socket. This should cure flaky behavior on
8699 a lot of those systems. [David Robinson]
8701 *) AddType, AddEncoding, and AddLanguage directives take multiple
8702 extensions on a single command line [David Robinson]
8704 *) UserDir can be disabled for a given virtual host by saying
8705 "UserDir disabled" in the <VirtualHost> section --- it was a bug
8706 that this didn't work. [David Robinson]
8708 *) Compiles on QNX [Ben Laurie]
8710 *) Corrected parsing of ctime time format [David Robinson]
8712 *) httpd does a perror() before exiting if it can't log its pid
8713 to the PidFile, to make diagnosing the error a bit easier.
8716 *) <!--#include file="..."--> can no longer include files in the
8717 parent directory, for NCSA back-compatibility. [David Robinson]
8719 *) '~' is *not* escaped in URIs generated for directory listings
8722 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
8724 *) Fixed bug involving handling URIs with escaped %-characters
8725 in redirects [David Robinson]
8727 Changes with Apache 0.8.15 14 Oct 1995
8729 *) Switched to new, simpler license
8731 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
8733 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
8735 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
8737 *) Correctly handles internal redirects to files with names containing '%'
8740 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
8742 *) Use geteuid() rather than getuid() to see if we have root privilege,
8743 so that server correctly resets privilege if run setuid root. [Andrew
8746 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
8749 *) Fix relative URLs in imagemap files [Randy Terbush]
8751 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
8754 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
8755 entries all name the same one. [David Robinson]
8757 *) Fix directory listings with filenames containing unusual characters
8760 *) Better URI-escaping for generated URIs in directories with filenames
8761 containing unusual characters [Ben Laurie]
8763 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
8765 *) Unblock alarms on error return from spawn_child() [David Robinson]
8767 *) Sample Config files have extra note for SCO users [Ben Laurie]
8769 *) Configuration has note for HP-UX users [Rob Hartill]
8771 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
8773 *) Nuked bogus #define in httpd.h [David Robinson]
8775 *) Better test for whether a system has setrlimit() [David Robinson]
8777 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
8779 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
8782 Changes with Apache 0.8.14 19 Sep 1995
8784 *) Compiles on SCO ODT 3.0 [Ben Laurie]
8786 *) AddDescription works (better) [Ben Laurie]
8788 *) Leaves an intelligible error diagnostic when it can't set group
8789 privileges on standalone startup [Andrew Wilson]
8791 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
8792 that machine, which claims to be BSD but does not support RLIMIT.
8795 *) gcc -Wall no longer complains about an unused variable when util.c
8796 is compiled with -DMINIMAL_DNS [Andrew Wilson]
8798 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
8800 Changes with Apache 0.8.13 07 Sep 1995
8802 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
8804 *) Have built-in imagemap code recognize & honor Point directive [James
8807 *) Generate cleaner directory listings in directories with a mix of
8808 long and short filenames [Rob Hartill]
8810 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
8812 *) Properly default ServerName for virtual servers [Robert Thau]
8814 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
8815 Paul Richards and a cast of thousands...]
8817 *) On self-identified BSD systems (we don't try to guess any more),
8818 allocate a few extra file descriptors per virtual host with setrlimit,
8819 if we can, to avoid running out. [Randy Terbush]
8821 *) Write 22-character lock file name into buffer with enough space
8822 on startup [Konstantin Olchanski]
8824 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
8827 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
8829 *) Suppress -Wall warning by initializing variable in negotiation code
8830 [Tobias Weingartner]
8832 Changes with Apache 0.8.12 31 Aug 1995
8834 *) Doesn't pause three seconds after including a CGI script which is
8835 too slow to die off (this is done by not even trying to kill off
8836 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
8837 after the entire document has been processed). [Robert Thau]
8839 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
8841 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
8843 *) Allows .htaccess files to override <Directory> sections naming the
8844 same directory [David Robinson]
8846 *) Removed an efficiency hack in sub_req_lookup_uri which was
8847 causing certain extremely marginal cases (e.g., ScriptAlias of a
8848 *particular* index.html file) to fail. [David Robinson]
8850 *) Doesn't log an error when the requested URI requires
8851 authentication, but no auth header line was supplied by the
8852 client; this is a normal condition (the client doesn't no auth is
8853 needed here yet). [Robert Thau]
8855 *) Behaves more sanely when the name server loses its mind [Sean Welch]
8857 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
8859 *) RFC931 code no longer passes out name of prior clients on current
8860 requests if the current request came from a server that doesn't
8861 do RFC931. [David Robinson]
8863 *) Configuration script accepts "Module" lines with trailing whitespace.
8866 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
8868 *) Cleaned up comments in mod_cgi.c [Robert Thau]
8870 Changes with Apache 0.8.11 24 Aug 1995
8872 *) Wildcard <Directory> specifications work. [Robert Thau]
8874 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
8876 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
8877 the file being requested itself, in addition to the directories leading
8878 up to it. [Robert Thau]
8880 *) Logs access failures due to symlink checks or invalid client address
8881 in the error log [Roy Fielding, Robert Thau]
8883 *) Symlink checks deal correctly with systems where lstat of
8884 "/path/to/some/link/" follows the link. [Thau, Fielding]
8886 *) Doesn't reset DirectoryIndex to 'index.html' when
8887 other directory options are set in a .htaccess file. [Robert Thau]
8889 *) Clarified init code and nuked bogus warning in mod_access.c
8892 *) Corrected several directives in sample srm.conf
8893 --- includes corrections to directory indexing icon-related directives
8894 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
8895 icons for encodings right, and turning on AddEncoding by default).
8898 *) Corrected descriptions of args to AddIcon and AddAlt in command table
8901 *) INSTALL & README mention "contributed modules" directory [Brian
8904 *) Fixed English in the license language... "for for" --> "for".
8907 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
8908 mod_alias.c, merging it almost completely with handling of Alias, and
8909 adding a 'notes' field to the request_rec which allows the CGI module
8910 to discover whether the Alias module has put this request through
8911 ScriptAlias (which it needs to know for back-compatibility, as the old
8912 NCSA code did not check Options ExecCGI in ScriptAlias directories).
8915 Changes with Apache 0.8.10 18 Aug 1995
8917 *) AllowOverride applies to the named directory, and not just
8918 subdirectories. [David Robinson]
8920 *) Do locking for accept() exclusion (on systems that need it)
8921 using a special file created for the purpose in /usr/tmp, and
8922 not the error log; using the error log causes real problems
8923 if it's NFS-mounted; this is known to be the cause of a whole
8924 lot of "server hang" problems with Solaris. [David Robinson;
8925 thanks to Merten Schumann for help diagnosing the problem].
8927 Changes with Apache 0.8.9 12 Aug 1995
8929 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
8931 *) Nested includes see environment variables of the including document,
8932 for NCSA bug-compatibility (some sites have standard footer includes
8933 which try to print out the last-modified date). [Eric Hagberg/Robert
8936 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
8937 URI as a CGI script, even if it would have been treated as something
8938 else if requested directly, for NCSA back-compatibility. (Note that
8939 this means that people who know the name of the script can see the
8940 code just by asking for it). [Robert Thau]
8942 *) New version of dbmmanage script included in support directory as
8945 *) Check if scoreboard file couldn't be opened, and say so, rather
8946 then going insane [David Robinson]
8948 *) POST to CGI works on A/UX [Jim Jagielski]
8950 *) AddIcon and AddAlt commands work properly [Rob Hartill]
8952 *) NCSA server push works properly --- the Arena bug compatibility
8953 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
8954 if you still want the workaround). [Rob Hartill]
8956 *) If client didn't submit any Accept-encodings, ignore encodings in
8957 content negotiation. (NB this will all have to be reworked anyway
8958 for the new HTTP draft). [Florent Guillaume]
8960 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
8962 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
8964 *) Give Redirect priority over Alias, for NCSA bug compatibility
8967 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
8968 paralleling earlier bug fix for CGI [David Robinson]
8970 *) If DBM auth is improperly configured, report a server error and don't
8973 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
8974 it seems to work well enough without it (even in a 10 hits/sec
8975 workout), and the overhead for the locking under A/UX is
8976 alarmingly high (though it is very low on other systems).
8977 [Eric Hagberg, Jim Jagielski]
8979 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
8981 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
8982 Behlendorf/Eric Hagberg]
8984 *) More improvements to default Configuration for A/UX [Jim Jagielski]
8986 *) Compiles clean on NEXT [Rob Hartill]
8988 *) Compiles clean on SGI [Robert Thau]
8990 Changes with Apache 0.8.8 08 Aug 1995
8992 *) SunOS library prototypes now never included unless explicitly
8993 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
8994 people using GNU libc on SunOS are screwed by prototypes for the
8997 (Those who wish to compile clean with gcc -Wall on a standard
8998 SunOS setup need the prototypes, and may obtain them using
8999 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
9000 with nonstandard libraries are presumably competent to make their
9003 *) Strips trailing '/' characters off both args to the Alias command,
9004 to make 'Alias /foo/ /bar/' work.
9006 Changes with Apache 0.8.7 03 Aug 1995
9008 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
9009 [reported by David Robinson]
9011 *) Compiles clean on OSF/1 [David Robinson]
9013 *) Added some of the more recent significant changes (AddLanguage stuff,
9014 experimental LogFormat support) to CHANGES file in distribution root
9017 Changes with Apache 0.8.6 02 Aug 1995
9019 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
9020 (If you actually wanted a conditional GET which bypassed the cache, you
9021 couldn't get it). [Reported by Roy Fielding]
9023 *) Properly terminate headers on '304 Not Modified' replies to conditional
9024 GETs --- no browser we can find cares much, but the CERN proxy chokes.
9025 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
9027 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
9029 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
9030 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
9031 and older versions don't set the __SUNPRO_C preprocessor variable). On
9032 all other systems, these are never used anyway. [Reported by Mark Cox].
9034 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
9036 Changes with Apache 0.8.5 01 Aug 1995
9038 *) Added last-minute configurable log experiment, as optional module
9040 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
9041 properly. (One-line fix to http_protocol.c).
9043 *) Work around bogus behavior when reloading from Netscape.
9044 It's Netscape's bug --- for some reason they expect a request with
9045 If-modified-since: to not function as a conditional GET if it also
9046 comes with Pragma: no-cache, which is way out of line with the HTTP
9047 spec (according to Roy Fielding, the redactor).
9049 *) Added parameter to set maximum number of server processes.
9051 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
9054 *) IdentityCheck bugfix [Chuck Murcko].
9056 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
9058 *) More sample config file corrections; add extension to AddType for
9059 *.asis, move AddType generic description to its proper place, and
9060 fix miscellaneous typos. [ Alexei Kosut ]
9062 *) Deleted the *other* reference to the regents from the Berkeley
9063 legal disclaimer (everyplace).
9065 *) Nuked Shambhala name from src/README; had already cleaned it out
9068 Changes with Apache 0.8.4
9070 *) Changes to server-pool management parms --- renamed current
9071 StartServers to MinSpareServers, created separate StartServers
9072 parameter which means what it says, and renamed MaxServers to
9073 MaxSpareServers (though the old name still works, for NCSA 1.4
9074 back-compatibility). The old names were generally regarded as
9075 too confusing. Also altered "docs" in sample config files.
9077 *) More improvements to default config files ---
9078 sample directives (commented out) for XBitHack, BindAddress,
9079 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
9080 defaults, AddTypes for send-as-is and imagemap magic types, and
9081 improvements to samples for DirectoryIndex [Alexei Kosut]
9083 *) Yet more improvements to default config files --- changes to
9084 Alexei's sample AddLanguage directives, and sample LanguagePriority
9085 [ Florent Guillaume ]
9087 *) Set config file locations properly if not set in httpd.conf
9090 *) Don't escape URIs in internal redirects multiple times; don't
9091 do that when translating PATH_INFO to PATH_TRANSLATED either.
9094 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
9096 Changes with Apache 0.8.3
9098 *) Edited distribution README to *briefly* summarize installation
9099 procedures, and give a pointer to the INSTALL file in the src/
9102 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
9103 recent NCSA distributions.
9105 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
9106 exist for the same directory, use both and don't segfault. [Reported
9109 *) Proper makefile dependencies [David Robinson]
9111 *) Note (re)starts in error log --- reported by Rob Hartill.
9113 *) Only call no2slash() after get_path_info() has been done, to
9114 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
9115 reported by Andrew Wilson, though this one is probably a real bug]
9117 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
9118 dump core when Referer is not supplied. [Randy Terbush]
9120 *) Lightly edited sample config files to refer people to our documentation
9121 instead of NCSA's, and to list Rob McCool as *original* author (also
9122 deleted his old, and no doubt non-functional email address). Would be
9123 nice to have examples of new features...
9125 Changes with Apache 0.8.2 19 Jul 1995
9127 *) Added AddLanuage code [Florent Guillaume]
9129 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
9131 *) All sorts of problems when MultiViews finds a directory. It would
9132 be nice if mod_dir.c was robust enough to handle that, but for now,
9133 just punt. [reported by Brian Behlendorf]
9135 *) Wait for all children on restart, to make sure that the old socket
9136 is gone and we can reopen it. [reported by Randy Terbush]
9138 *) Imagemap module is enabled in default Configuration
9140 *) RefererLog and UserAgentLog modules properly default the logfile
9143 *) Mark Cox's mod_cookies added to the distribution as an optional
9144 module (commented out in the default Configuration, and noted as
9145 an experiment, along with mod_dld). [Mark Cox]
9147 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
9149 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
9151 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
9153 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
9156 Changes with Apache 0.8.1
9158 *) New imagemap module [Randy Terbush]
9160 *) Replacement referer log module with NCSA-compatible RefererIgnore
9161 [Matthew Gray again]
9163 *) Don't mung directory listings with very long filenames.
9166 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
9168 *) New config script. See INSTALL for info. [Robert Thau]
9170 *) Scoreboard mechanism for regulating the number of extant server
9171 processes. MaxServers and StartServers defaults are the same as
9172 for NCSA, but the meanings are slightly different. (Actually,
9173 I should probably lower the MaxServers default to 10).
9175 Before asking for a new connection, each server process checks
9176 the number of other servers which are also waiting for a
9177 connection. If there are more than MaxServers, it quietly dies
9178 off. Conversely, every second, the root, or caretaker, process
9179 looks to see how many servers are waiting for a new connection;
9180 if there are fewer than StartServers, it starts a new one. This
9181 does not depend on the number of server processes already extant.
9182 The accounting is arranged through a "scoreboard" file, named
9183 /tmp/htstatus.*, on which each process has an independent file
9184 descriptor (they need to seek without interference).
9186 The end effect is that MaxServers is the maximum number of
9187 servers on an *inactive* server machine, but more will be forked
9188 off to handle unusually heavy loads (or unusually slow clients);
9189 these will die off when they are no longer needed --- without
9190 reverting to the overhead of full forking operation. There is a
9191 hard maximum of 150 server processes compiled in, largely to
9192 avoid forking out of control and dragging the machine down.
9193 (This is arguably too high).
9195 In my server endurance tests, this mechanism did not appear to
9196 impose any significant overhead, even after I forced it to put the
9197 scoreboard file on a normal filesystem (which might have more
9198 overhead than tmpfs). [Robert Thau]
9200 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
9203 *) Read .htaccess files even in directory with <Directory> section.
9204 (Former incompatibility noted on mailing list, now fixed). [Robert
9207 *) "HEAD /" gives the client a "Bad Request" error message, rather
9208 than trying to send no body *and* no headers. [Cliff Skolnick].
9210 *) Don't produce double error reports for some very obscure cases
9211 mainly involving auth configuration (the "all modules decline to
9212 handle" case which is a sure sign of a server bug in most cases,
9213 but also happens when authentication is badly misconfigured).
9216 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
9217 it's *for*, and this sort of thing really shouldn't be cluttering
9218 up the Makefile). [Robert Thau]
9220 *) Incidental code cleanups in http_main.c --- stop dragging
9221 sa_client around; just declare it where used. [Robert Thau]
9223 *) Another acc-related fix. (It doesn't like const char
9224 in some places...). [Mark Cox]
9226 Changes with Shambhala 0.6.1 13 Jul 1995
9228 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
9229 Also, fixed auth typo in http_protocol.c unmasked by this fix.
9231 *) Compiles clean with acc on SunOS [Paul Sutton]
9233 *) Reordered modules in modules.c so that Redirect takes priority
9234 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
9235 believe it or not, he has an actual site with a ScriptAlias and
9236 a Redirect declared for the *exact same directory*. Even *my*
9237 compatibility fetish wouldn't motivate me to fix this if the fix
9238 required any effort, but it doesn't, so what the hey.
9240 *) Fixed to properly default several server_rec fields for virtual
9241 servers from the corresponding fields in the main server_rec.
9242 [Cliff Skolnick --- 'port' was a particular irritant].
9244 *) No longer kills off nph- child processes before they are
9245 finished sending output. [Matthew Gray]
9247 Changes with Shambhala 0.6.0 10 Jul 1995
9249 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
9250 the connection to the client in an "aborted" state, but otherwise
9251 allow whatever handlers are running to clean up. hard_timeout()s
9252 abort the request in progress completely; anything not tied to some
9253 resource pool cleanup will leak. They're still around because I
9254 haven't yet come up with a more elegant way of handling
9255 timeouts when talking to something that isn't the client. The
9256 default_handler and the dir_handler now use soft timeouts, largely
9257 so I can test the feature. [Robert Thau]
9259 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
9260 the case of log handlers dying prematurely is probably handled VERY
9261 gracelessly at this point, and if the logger stops reading input,
9262 the server will hang. (It is known to correctly restart the
9263 logging process on server restart; this is (should be!) going through
9264 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
9265 script). [Robert Thau]
9267 *) asis files supported (new module). [Robert Thau]
9269 *) IdentityCheck code is compiled in, but has not been tested. (I
9270 don't know anyone who runs identd). [Robert Thau]
9272 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
9273 came in with the request, for NCSA bug-compatibility. [Robert Thau]
9275 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
9277 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
9278 as timeouts are not in scope. [Robert Thau]
9280 *) quoted-string args in config files now handled correctly (doesn't drop
9281 the last character). [Robert Thau; reported by Randy Terbush]
9283 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
9284 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
9286 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
9287 default default type); the former default default behavior when all
9288 type-checkers defaulted had been a core dump. [Paul Sutton]
9290 *) Copy filenames out of the struct dirent when indexing
9291 directories. (On Linux, readdir() returns a pointer to the same
9292 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
9294 Changes with Shambhala 0.5.3 [not released]
9296 *) Default response handler notes "file not found" in the error log,
9297 if the file was not found. [Cliff Skolnick].
9299 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
9300 code no longer sets up bogus PATH_INFO which fakes out the directory
9301 handler). [Cliff Skolnick]
9303 Changes with Shambhala 0.5.2 06 Jul 1995
9305 *) Changes to http_main.c --- root server no longer plays silly
9306 games with SIGCHLD, and so now detects and replaces dying
9307 children. Child processes just die on SIGTERM, without taking
9308 the whole process group with them. Potential problem --- if any
9309 child process refuses to die, we hang in restart.
9310 MaxRequestsPerChild may still not work, but it certainly works
9311 better than it did before this! [Robert Thau]
9313 *) mod_dir.c bug fixes: ReadmeName and HeaderName
9314 work (or work better, at least); over-long description lines
9315 properly terminated. [Mark Cox]
9317 *) http_request.c now calls unescape_url() more places where it
9318 should [Paul Sutton].
9320 *) More directory handling bugs (reported by Cox)
9321 Parent Directory link is now set correctly. [Robert Thau]
9323 Changes with Shambhala 0.5.1 04 Jul 1995
9325 *) Generalized cleanup interface in alloc.c --- any function can be
9326 registered with alloc.c as a cleanup for a resource pool;
9327 tracking of files and file descriptors has been reimplemented in
9328 terms of this interface, so I can give it some sort of a test.
9331 *) More changes in alloc.c --- new cleanup_for_exec() function,
9332 which tracks down and closes all file descriptors which have been
9333 registered with the alloc.c machinery before the server exec()s a
9334 child process for CGI or <!--#exec-->. CGI children now get
9335 started with exactly three file descriptors open. Hopefully,
9336 this cures the problem Rob H. was having with overly persistent
9337 CGI connections. [Robert Thau]
9339 *) Mutual exclusion around the accept() in child_main() --- this is
9340 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
9341 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
9342 This uses fcntl(F_SETLK,...) on the error log descriptor because
9343 flock() on that descriptor won't work on systems which have BSD
9344 flock() semantics, including (I think) Linux 1.3 and Solaris.
9346 This does work on SunOS (when the server is idle, only one
9347 process in the pool is waiting on accept()); it *ought* to work
9348 on the other systems. [Robert Thau]
9350 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
9352 *) sizeof(*sa_client) bugfix from [Rob Hartill]
9354 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
9356 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
9357 be unnecessary if I go to the revised timeout-handling scheme).
9360 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
9361 string) even if none came in with the request. [Robert Thau]
9363 *) CHANGES file added to distribution ;-).
9365 Changes with Shambhala 0.4.5
9367 *) mod_dld --- early dynamic loading support [rst]
9368 *) Add wildcard content handlers for XBITHACK; default_hander now
9369 invoked with that mechanism (as a handler hanging off mod_core) [rst]
9370 *) XBITHACK supported as a wildcard content-handler, and
9371 configurable at run-time (not just at compile time, as in the
9372 "patchy server" releases) [rst]
9374 Changes with Shambhala 0.4.4 30 Jun 1995
9376 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
9377 *) Handle Addtype x/y .z [rst, reported by Cox]
9379 Changes with Shambhala 0.4.3
9381 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
9382 synonymous [rst, terbush]
9384 Changes with Shambhala 0.4.1 28 Jun 1995
9386 *) First-cut virtual host implementation; some refit in the config
9387 reading code, and log management, was necessary to support this [rst]
9388 *) Sub-pool machinery, originally added to avoid excessive storage
9389 allocation on listings of large directories (which turned out to
9390 be the problem that the 0.3 storage accounting was added to
9391 find). Subrequests and mod_dir changed to use subpools. [rst]
9392 *) More memory debugging --- free list consistency checks. [rst]
9393 *) Added err_headers to request_rec, with support elsewhere [rst]
9394 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
9396 Changes with Shambhala 0.3 19 Jun 1995
9398 *) Switch ONE_PROCESS to a runtime command-line option (-X)
9399 *) Don't compile in mod_ai_backcompat by default
9400 *) Switch name of server from Apache to Shambhala in Makefile
9401 *) Add some accounting routines to track memory usage in the pools,
9404 Changes with Shambhala 0.2
9406 *) Set DOCUMENT_ROOT CGI variable
9407 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
9408 *) Add critical section protection to handling of cleanup structures
9410 *) Significant code reorg within the server core to group related
9411 functions together [rst]
9412 *) Correctly handle clients that hang up before sending any request
9414 *) Replace dying child processes. [rst]
9416 Changes with Shambhala 0.1 12 Jun 1995
9418 Major rewrite of the pre-existing "patchy server" codebase, by
9419 Robert Thau (rst). Significant portions of the server code, such
9420 as configuration-file handling and HTTP authentication support,
9421 were ripped out and rewritten from scratch. Code that was not
9422 completely rewritten was significantly altered.
9424 Major changes with this release include:
9426 *) Introduction of the module API; in request handling, the central
9427 machinery just dispatches to various modules, which actually do
9428 most of the work. Configuration handling is similar --- modules
9429 declare their own commands, and the central machinery just
9432 API features from shambhala/0.1 were substantially unchanged in
9433 Apache 1.0 and 1.1. (1.0 API features not yet present in this
9434 release, such as wildcard handlers and subpools, were added in
9435 subsequent Shambhala releases, and were also generally rst's
9438 *) This release included the following modules:
9440 mod_access (access control --- allow and deny directives),
9441 mod_alias (Alias and Redirect commands),
9442 mod_auth (straight HTTP authentication, based on flat-files)
9443 mod_auth_dbm (same, with dbm files)
9444 mod_cgi (CGI scripts and, in this release, ScriptAlias)
9445 mod_common_log (CLF access logs; later renamed mod_log_common)
9446 mod_dir (directory indexing)
9447 mod_include (server-side includes)
9448 mod_mime (AddType directives)
9449 mod_negotiation (content negotiation)
9450 mod_userdir (support for users' public_html directories)
9452 It also included a mod_ai_backcompat, which was a private hack
9453 for back-compatibility with rst's own AI-lab servers.
9455 All of these modules were substantially complete, and functional
9456 or nearly so (a few, which implemented features not in use at
9457 Thau's site, required patches of a few lines).
9459 *) sub-request machinery, to allow modules to determine how other
9460 modules would assign MIME types to a given file, or optionally
9461 serve its content (this is heavily used by mod_dir, mod_include
9462 and mod_negotiation).
9464 *) Resource pool system for keeping track of memory allocated and
9465 files opened in service of a particular request. Much of the
9466 code in the modules (when they weren't rewrites) was adjusted to
9467 replace a pervasive convention of using fixed-size buffers on
9468 the stack with an equally pervasive convention of using memory
9469 allocated with palloc().
9471 *) Reorganization of data structures associated with a given
9472 request to eliminate use of global variables and the troublesome
9473 unmunge_name function (used in NCSA and early Apache releases to
9474 attempt to determine the URI which mapped to a given filename
9475 --- a difficult proposition, given that it is easy to produce
9476 setups in which multiple URIs map to the same file).
9478 *) Source files renamed and rearranged
9480 *) Very simple pre-forking behavior --- parent process forked off a
9481 fixed number of children, and then just waited for SIGHUP.
9483 *) Other more minor changes too numerous to list.
9485 This release included modified versions of a lot of code from the
9486 Apache 0.6.4 public release, plus an early pre-forking patch
9487 codeveloped by Robert Thau and Rob Hartill.
9489 Changes with Apache 0.7.3 20 Jun 1995
9491 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
9492 were incorporated by Rob Hartill on the main branch while Robert Thau
9493 worked on the Shambhala rewrite above. Most were merged into the
9494 Shambala architecture after Apache 0.8.0.
9496 Changes with Apache 0.6.4 13 May 1995
9498 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
9501 Changes with Apache 0.5.1 10 Apr 1995
9503 Changes with Apache 0.4 02 Apr 1995
9505 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
9508 Changes with Apache 0.3 24 Mar 1995
9510 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
9513 Changes with Apache 0.2 18 Mar 1995
9515 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
9516 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
9517 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
