1 Changes with Apache 2.0.33-dev
3 *) Fix for multiple file buckets on Win32, where the first file
4 bucket would cause the immediate closure of the socket on any
5 non-keepalive requests. [Ryan Morgan <rmorgan@covalent.net>]
7 *) Correct Win32 failure of mmap of a segment beyond start of the
8 file; fixes large SSL and similar transfers. [William Rowe]
11 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
12 multi-process mode to not "daemonize" while detaching from the
13 controlling terminal. This is necessary for Apache to work with
14 process-management tools like AIX's "System Resource Controller"
15 as well as Dan Bernstein's "daemontools".
16 [Jos Backus <josb@cncdsl.com>, Aaron Bannert]
18 *) Convert mod_auth_digest to use the new apr_global_mutex_t
21 *) fix bug in mod-include where it wouldn't send a unmatched
22 part if it was at the end of a bucket [Ian Holsman]
24 *) worker MPM: Improve logging of errors with the interface between
25 the listener thread and worker threads. [Jeff Trawick]
27 *) Some browsers ignore cookies that have been merged into a
28 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
29 are now unmerged in the http proxy before being sent to the
30 client. [Graham Leggett]
32 *) Fix a problem with proxy where each entry of a duplicated
33 header such as Set-Cookie would overwrite and obliterate the
34 previous value of the header, resulting in multiple header
35 values (like cookies) going missing.
36 [Graham Leggett, Joshua Slive]
38 *) Add the server-limit and thread-limit values to the scoreboard
39 for the sake of third-party applications.
40 [Adam Sussman <myddryn@vishnu.vidya.com>]
42 *) Fix segfault when proxy recieves an invalid HTTP response [Ian Holsman]
44 *) OS/390: Get make install to properly copy DSO modules.
47 *) Win32: Fix bug in mod_status with displaying "Restart Time"
51 *) Fix IPv6 name-based virtual hosts. [Jeff Trawick]
53 *) Introduce AddOutputFilterByType directive. [Justin Erenkrantz]
55 *) Fix DEBUG_CGI support in mod_cgi. PR 9670, 9671.
56 [David MacKenzie <djm@pix.net>]
58 *) Fix incorrect check for script_in in mod_cgi. PR 9669.
59 [David MacKenzie <djm@pix.net>]
61 *) Fix segfault and display error when SSLMutex file can not be
62 created. [Adam Sussman <myddryn@vishnu.vidya.com>]
64 *) Add reference counting to mod_mem_cache cache objects to
65 better manage removing objects from the cache.
68 *) Change the verbage on the ScoreBoardFile in our default configs.
69 Also change the default to be commented out (unspecified) so we
70 get anonymous shared memory by default. [Aaron Bannert]
72 *) Implement new ScoreBoardFile directive logic. This affects how
73 we create the scoreboard's shared memory segment. If the directive
74 is present, a name-based segment is created. If the directive is
75 not present, first an anonymous segment is created, and if that
76 fails, a name-based segment is created from a file of the name
77 DEFAULT_SCOREBOARD. This gives third-party applications the
78 ability to access our scoreboard. [Aaron Bannert]
80 *) Allow mod_deflate to work with non-GET requests and properly send
81 Content-Lengths. [Sander Striker <striker@apache.org>]
83 *) Fix ap_directory_merge() to correctly merge configs when there is
84 no <Directory /> block. [Justin Erenkrantz, William Rowe]
86 *) Remove spurious debug messsages that are normal under HTTP
87 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
89 *) Fix a bug in mod_cgid that would prevent proper shutdown death
90 of the cgid process. [Aaron Bannert]
92 *) Add signal handling back in to the worker MPM for the one_process
93 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
95 *) Performance: Reuse per-connection transaction pools in the
96 worker MPM, rather than destroying and recreating them. [Brian Pane]
98 *) Remove all signals from the worker MPM's child process. Instead,
99 the parent uses the Pipe of Death for all communication with the
100 child processes. [Ryan Bloom]
102 Changes with Apache 2.0.32
104 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
105 default if the directive is not specified. This mirrors older
106 behavior without changes to the httpd.conf. [William Rowe]
108 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
109 the service, mpm and logging code, and bugs in apr_file_open_stderr
110 and apr_file_dup2 functions. Win2K/XP services have no handles
111 associated for stdin/out/err, which caused unpredictable behavior
112 in the prior release. [William Rowe, Bill Stoddard]
114 *) Win32: simplify the Application Event Log messages, since there isn't
115 likely to be 'more information in the error log' before an error log
116 has been opened. [William Rowe]
118 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
119 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
121 *) Win32: apache -k shutdown now behaves like apache -k stop.
124 *) Fix prefork to not kill the parent if a child hits a resource shortage
125 on accept(). [Greg Ames]
127 *) Fix seg faults that occur when what should be the httpd request line
128 starts with \r\n followed by garbage. [Greg Ames]
130 *) Allow statically linked support binaries with the new
131 --enable-static-support flag, and enable this behavior in
132 the binbuild script. Also add a new --enable-static-htdbm
133 flag. [Aaron Bannert]
135 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
136 do only one stat() call when generating the directory listings.
139 *) Fix resolve_symlink to save the original symlink name if known.
142 *) Be a bit more sane with regard to CanonicalNames. If the user has
143 specified they want to use the CanonicalName, but they have not
144 configured a port with the ServerName, then use the same port that
145 the original request used. [Ryan Bloom and Ken Coar]
147 *) In core_input_filter, check for an empty brigade after
148 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
149 client says it will post some data but we get FIN before any
150 data arrives. [Jeff Trawick]
152 *) Not being able to bind to the socket is a fatal error. We should
153 print an error to the console, and return a non-zero status code.
154 With these changes, all of the Unix MPMs do that correctly.
157 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
158 through to CGI scripts. PR 9163
159 [Brian Reid <breid@customlogic.com>,
160 Zvi Har'El <rl@math.technion.ac.il>]
162 *) binbuild.sh: Make sure that we use the expat from our source
163 tree so that there aren't any surprises on the target machine.
166 *) mod_cgid: Add retry logic for when the daemon can't fork fast
167 enough to keep up with new requests. Start using
168 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
169 when we can't talk to the daemon. [Jeff Trawick]
171 *) apxs: LTFLAGS envvar can override default libtool options. Try
172 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
173 the covers. [Jeff Trawick]
175 *) The Location: response header field, used for external
176 redirect, *must* be an absoluteURI. The Redirect directive
177 tested for that, but RedirectMatch didn't -- it would allow
178 almost anything through. Now it will try to turn an abs_path
179 into an absoluteURI, but it will correctly varf like Redirect
180 if the final redirection target isn't an absoluteURI. [Ken Coar]
182 Changes with Apache 2.0.31
184 *) Create the scoreboard (in the parent) in a global pool context,
185 so it survives graceful restarts. This fixes a SEGV during
186 graceful restarts. [Aaron Bannert]
188 *) Add a timeout option to the proxy code 'ProxyTimeout'
191 *) FTP directory listings are now always retrieved in ASCII mode.
192 The FTP proxy properly escapes URI's and HTML in the generated
193 listing, and escapes the path components when talking to the FTP
194 server. It is now possible to browse the root directory by using
195 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
196 Also, the last path component may contain wildcard characters
197 '*' and '?', and if they do, a directory listing is created instead
198 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
201 *) Added single-listener unserialized accept support to the
202 worker MPM [Brian Pane]
204 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
205 the incoming host header through to the proxied server
206 [Geoff <g.russell@ieee.org>]
208 *) New Directive Option for ProxyPass. It now can block a location
209 from being proxied [Jukka Pihl <jukka.pihl@entirem.com>]
211 *) Don't let the default handler try to serve a raw directory. At
212 best you get gibberish. Much worse things can happen depending
213 on the OS. [Jeff Trawick]
215 *) Change the pre_config hook to return a value. Modules can now emit
216 an error message and then cause the server to quit gracefully during
217 startup. This required a bump to the MMN. [Aaron Bannert]
219 *) Fix some unix socket descriptor leaks in the handler side of
220 mod_cgid (the part that runs in the server process). Whack a
221 silly "close(-1)" in the handler too. [Jeff Trawick]
223 *) Change the pre_mpm hook to return a value, so that scoreboard
224 init errors percolate up to code that knows how to exit
225 cleanly. This required a bump to the MMN. [Jeff Trawick]
227 *) Add the socket back to the conn_rec and remove the create_connection
228 hook. The create_connection hook had a design flaw that did not
229 allow creating connections based on vhost info. [Bill Stoddard]
231 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
232 Resolves the common case of using negotation to resolve the request
233 /script/foo for /script.cgi/foo. [William Rowe]
235 *) Added new functions ap_add_(input|output)_filter_handle to
236 allow modules to bypass the usual filter name lookup when
237 adding hard-coded filters to a request [Brian Pane]
239 *) caching should now work on subrequests (still very experimental)
242 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
244 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
247 *) Refactor ap_rgetline so that it does not use an internal brigade.
248 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
250 *) Remove mod_auth_db. [Justin Erenkrantz]
252 *) Do not install unnecessary pcre headers like config.h and internal.h.
253 [Joe Orton <joe@manyfish.co.uk>]
255 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
256 (as it does for a normal request). quick_handled sub-requests now work
257 in mod-include [Ian Holsman]
259 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
260 'CONTENT' one, as it needs to run AFTER all content headers
262 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
265 *) Split out blocking from the mode in the input filters.
268 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
270 *) Cause Win32 to capture all child-worker process errors in
271 Apache to the main server error log, until the child can
272 open its own error logs. [William Rowe]
274 *) HPUX 11.*: Do not kill the child process when accept()
275 returns ENOBUFS on HPUX 11.*. (ported from a 1.3 patch
276 by [madhusudan_mathihalli@hp.com])
279 *) Fix a problem in the parsing of the <Proxy foo> directive.
282 *) rewrite of mod_ssl input filter for better performance and less
283 memory usage [Doug MacEachern]
285 *) allow quick_handler to be run on subrequests. [Ian Holsman]
287 *) mod_dav now asks its provider to place content directly into the
288 filter stack when handling a GET request. The mod_dav/provider
289 API has changed, so providers need to be updated. [Greg Stein]
291 *) Clear the output socket descriptor in unixd_accept() to make sure
292 we don't supply a bogus socket to the caller if the accept fails.
293 This caused problems with the worker MPM, which tried to process
294 the returned socket if it was non-NULL. [Brian Pane]
296 *) Move a check for an empty brigade to the start of core input filter
297 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
299 *) Add FileETag directive to allow configurable control of what
300 data are used to form ETag values for file-based URIs. MMN
301 bumped to 20020111 because of fields added to the end of
302 the core_dir_config structure. [Ken Coar]
304 *) Fix a segfault in mod_rewrite's logging code caused by passing the
305 wrong config to ap_get_remote_host(). [Jeff Trawick]
307 *) Allow mod_cgid to work from a binary distribution install by
308 using 755 for the permissions on the log directory instead of
311 *) Fixed a segfault that happened during graceful shutdown (or when
312 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
314 *) Split all Win32 modules [excluding the core components mod_core,
315 mod_so, mod_win32 and the winnt mpm] into individual loadable
316 modules, so the administrator may individually disable the former
317 compiled-in modules by simply commenting out their LoadModule
318 directives. [William Rowe]
320 *) Saved Win32 module authors and porters many future headaches, by
321 duplicating the appropriate .h files such as os.h into the include
322 directory, including in the build tree. [William Rowe]
324 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
325 Use SSL functions/macros instead of directly dereferencing SSL
326 structures wherever possible.
327 Add type-casts for the cases where functions return a generic pointer.
328 Add $SSL/include to configure search path.
329 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
331 *) Moved several pointers out of the shared Scoreboard so it is
332 more portable, and will present the vhost name across server
333 generation restarts. [William Rowe]
335 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
338 Changes with Apache 2.0.30
340 *) Fix the main bug for FreeBSD and threaded MPM's. There are
341 still issues (see STATUS) but at least the server will now
342 run without crashing the machine.
343 [David Reid, Aaron Bannert, Justin Erenkrantz]
345 *) Fix a typo in mod_deflate's m4 config section.
346 [albert chin (china@thewrittenword.com)]
348 *) Fix a couple of mod_proxy problems forwarding HTTP connections
349 and handling CONNECT:
350 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
351 (2) Proxy failed to connect when the first IP address returned by
352 the resolver was unreachable but a secondary IP address was.
355 *) Fix the module identifer as shown in the docs for various core
356 modules (e.g., the identifer for mod_log_config was previously
357 listed as config_log_module). PR #9338
358 [James Watson <ap2bug@sowega.org>]
360 *) Fix LimitRequestBody directive by placing it in the HTTP
361 filter. [Justin Erenkrantz]
363 *) Fix mod_proxy seg fault when the proxied server returns
364 an HTTP/0.9 response or a bogus status line.
367 *) Prevent mod_proxy from truncating one character off the
368 end of the status line returned from the proxied server.
369 [Adam Sussman, Bill Stoddard]
371 *) Eliminate loop in ap_proxy_string_read().
372 [Adam Sussman, Bill Stoddard]
374 *) Provide $0..$9 results from mod_include regex parsing.
377 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
379 *) Introduced the ForceLanguagePriority directive, to prevent
380 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
381 when using Multiviews. [William Rowe]
383 *) Fix a problem which prevented mod_cgid and suexec from working
384 together reliably [Greg Ames]
386 *) Remove the call to exit() from within mod_auth_digest's post_config
387 phase. [Aaron Bannert]
389 *) Fix a problem in mod_auth_digest that could potentially cause
390 problems with initialized static data on a system that uses DSOs.
393 *) Fix a segfault in the worker MPM that could happen during
394 child process exits. [Brian Pane, Aaron Bannert]
396 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
398 *) Fix matching of vhosts by ip address so we find IPv4
399 vhost address when target address is v4-mapped form of
400 that address. [Jeff Trawick]
402 *) More performance tweaks to the BNDM string-search algorithm
403 used to find "<!--#" tokens in mod_include [Brian Pane]
405 *) Miscellaneous small performance fixes: optimized away various
406 string copy operations and removed large temp buffers from
407 the stack [Brian Pane]
409 *) Fixed startup segfault that occurred when a VirtualHost
410 directive had a port but no address [Brian Pane]
412 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
414 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
415 if oslevel < WINNT. This should fix several problems reported
416 Against 2.0.28 on Windows 98 [Bill Stoddard]
418 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
419 to fail. [Bill Stoddard]
421 *) Change core code to allow an MPM to set hard thread/server
422 limits at startup. prefork, worker, and perchild MPMs now have
423 directives to set these limits. [Jeff Trawick]
425 *) Win32: The async AcceptEx() event should be autoreset upon
426 successful completion of a wait (WaitForSingleObject). This
427 eliminates a number of spurious
428 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
431 *) Move any load library path environment variables out of
432 apachectl and into a separate environment variable file which
433 can be more easily tailored by the admin. The environment
434 variable file as built by Apache may have additional system-
435 specific settings. For example, on OS/390 we tailor the heap
436 settings to allow lots of threads. [Jeff Trawick]
438 *) Use the new APR pool code to reduce pool-related lock
439 contention in the worker MPM. [Sander Striker]
441 *) The POD no longer assumes the child is listening on 127.0.0.1
442 and now pulls the first hostname in the list of listeners to
443 perform the dummy connect on. This fixes a bug when the user
444 had configured the Listen directive for an IP other than
445 127.0.0.1. This would result in undead children and error
446 messages such as "Connection refused: connect to listener".
449 *) The worker MPM now respects the LockFile setting, needed to
450 avoid locking problems with NFS. [Jeff Trawick]
452 *) Fix segfault when worker MPM receives SIGHUP.
453 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
455 *) Fix bug that could potentially prevent the perchild MPM from
456 working with more than one vhost/uid. [Aaron Bannert]
458 *) Change make install and apxs -i processing of DSO modules to
459 perform special handling on platforms where libtool doesn't install
460 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
461 which prevented standard LoadModule statements from working.
464 *) Whenever mod_so is enabled (not just when there are DSOs for
465 our modules), do whatever special magic is required for compiling/
466 loading third-party modules. This allows third-party DSOs to
467 be used on an AIX build when there were no built-in modules
468 built as DSOs. (This should help on OS/390 and BeOS as well.)
471 *) Allow apxs to be used to build DSOs on AIX without requiring the
472 user to hard-code the list of import files. (This should help
473 on OS/390 and BeOS as well.) [Jeff Trawick]
475 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
476 PR 8563, 8919 [William Rowe]
478 *) Get binary builds working when libapr and libaprutil are built
481 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
482 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar@pacbell.net>,
483 Gary Hook <ghook@us.ibm.com>, Victor Orlikowski, Jeff Trawick]
485 *) Fix the handling of SSI directives in which the ">" of the
486 terminating "-->" is the last byte in a file [Brian Pane]
488 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
489 message that we had back in apache-1.3 and still have scattered
490 throughout our docs. [Aaron Bannert]
492 *) Prevent the Win32 port from continuing after encountering an
493 error in the command line args to apache. [William Rowe]
495 *) On a error in the proxy, make it write a line to the error log
498 *) Various mod_ssl performance improvements [Doug MacEachern]
500 Changes with Apache 2.0.29
502 *) Add buffering in core_output_filter to ensure that long
503 lists of small buckets don't cause small packet writes.
504 [Brian Pane, Ryan Bloom]
506 *) Fix the installation target to make sure that the manual is
507 installed in the correct location.
508 [Yoshifumi Hiramatsu <hiramatu@boreas.dti.ne.jp> and
509 Gomez Henri <hgomez@slib.fr>]
511 *) Fix the cmd command for mod_include. When we are processing
512 a cmd command, we do not want to use the r->filename to set
513 the command name. The command comes from the SSI tag. To do this,
514 I added a variable to the function that builds the command line
515 in mod_cgi. This allows the include_cmd function to specify
516 the command line itself. [Ryan Bloom]
518 *) Change open_logs hook to return a value, allowing you
519 to flag a error while opening logs
520 [Ian Holsman, Doug MacEachern]
522 *) Change post_config hook to return a value, allowing you
523 to flag a error post config
524 [Ian Holsman, Jeff Trawick]
526 *) Allow SUEXEC_BIN (the path to the suexec binary that is
527 hard-coded into the server) to be specified to the configure
528 script by the --with-suexec-bin parameter. [Aaron Bannert]
530 *) Fix segv in worker MPM following accept on pipe-of-death
533 *) Add mod_deflate to experimental.
534 [Ian Holsman, Justin Erenkrantz]
536 *) Bail out at configure time if an invalid MPM was specified.
537 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
539 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
540 configured [John Sterling <sterling@covalent.net>]
542 *) Fix apxs to use sbindir. [Henri Gomez <hgomez@slib.fr>]
544 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
546 *) Optimization for the BNDM string-search function in
547 mod_include. [Brian Pane]
549 *) Fixed the behavior of the XBitHack directive.
550 [Taketo Kabe <kabe@sra-tohoku.co.jp>, Cliff Woolley] PR#8804
552 *) The threaded MPM for Unix has been removed. Use the worker
553 MPM instead. [various]
555 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
556 in logging the error from a failed DNS lookup. [Jeff Trawick]
558 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
561 *) Get mod_cgid killed when a MPM exits due to a fatal error.
564 *) Fix a file descriptor leak in mod_include. When we include a
565 file, we use a sub-request, but we didn't destroy the sub-request
566 immediately, instead we waited until the original request was
567 done. This patch closes the sub-request as soon as the data is
568 done being generated. [Brian Pane <bpane@pacbell.net>]
570 *) Allow modules that add sockets to the ap_listeners list to
571 define the function that should be used to accept on that
572 socket. Each MPM can define their own function to use for
573 the accept function with the MPM_ACCEPT_FUNC macro. This
574 also abstracts out all of the Unix accept error handling
575 logic, which has become out of synch across Unix MPMs.
578 *) Fix a bug which would cause the response headers to be omitted
579 when sending a negotiated ErrorDocument because the required
580 filters were attached to the wrong request_rec.
581 [John Sterling <sterling@covalent.net>]
583 *) Remove commas from the end of the macros that define
584 directives that are used by MPMs. Prior to this patch,
585 you would use these macros without commas, which was unlike
586 the macros for any other directives. Now, the caller provides
587 the comma rather than the macro providing it. This makes
588 the macros look more like the rest of the directives.
589 [Ryan Bloom and Cliff Woolley]
591 *) Add 'redirect-carefully' environment option to disable sending
592 redirects under special circumstances. This is helpful for
593 Microsoft's WebFolders when accessing a directory resource via
594 DAV methods. [Justin Erenkrantz]
596 *) Begin to abstract out the underlying transport layer.
597 The first step is to remove the socket from the conn_rec,
598 the server now lives in a context that is passed to the
599 core's input and output filters. This forces us to be very
600 careful when adding calls that use the socket directly,
601 because the socket isn't available in most locations.
604 *) Really reset the MaxClients value in worker and threaded
605 when the configured value is not a multiple of the number
606 of threads per child. We said we did previously but we
607 forgot to. [Jeff Trawick]
609 *) Add Debian layout. [Daniel Stone <daniel@sfarc.net>]
611 *) If shared modules are requested and mod_so is not available,
612 produce a fatal config-time error. [Justin Erenkrantz]
614 *) Improve http2env's performance by cutting the work it has to
615 do. [Brian Pane <bpane@pacbell.net>]
617 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
618 [Brian Pane <bpane@pacbell.net>]
620 Changes with Apache 2.0.28
622 *) Fix infinite loop in mod_cgid.c.
623 [Dale Ghent <daleg@elemental.org>, Brian Pane <bpane@pacbell.net>]
625 *) When no port is given in a "ServerName host" directive, the
626 server_rec->port is now set to zero, not 80. That allows for
627 run-time deduction of the correct server port (depending on
628 SSL/plain, and depending also on the current setting of
629 UseCanonicalName). This change makes redirections
630 work, even with https:// connections. As in Apache-1.3, the
631 connection's actual port number is never used, only the ServerName
632 setting or the client's Host: setting. Documentation updated
633 to reflect the change. [Martin Kraemer]
635 *) Add a '%{note-name}e' argument to mod-headers, which works in
636 the same way as mod_log_confg. [Ian Holsman]
638 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
639 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
640 MPMs. [Cliff Woolley]
642 *) Introduce htdbm, a user management utility for db/dbm authorization
643 databases. [Mladen Turk <mturk@mappingsoft.com>]
645 *) Optimize usage of strlen and strcat in ap_directory_walk.
646 [Brian Pane <bpane@pacbell.net>]
648 Changes with Apache 2.0.27
650 *) Introduce an Apache mod_ssl initial configuration template
651 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
653 *) Fixed a memory leak in the getline parsing code that could
654 be triggered by arbitrarily large header lines. Requests
655 from the core input filter for single lines are now limited
656 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
658 *) Fix a truncation bug in how we print the port on the Via: header.
659 The routine that prints the Via: header now takes a length for
660 the port string. [Zvi Har'El <rl@math.technion.ac.il>]
662 *) Some syntax errors in mod_mime_magic's magic file can result
663 in a 500 error, which previously was unlogged. Now we log the
664 error. [Jeff Trawick]
666 *) Add the support/checkgid helper app, which checks the run-time
667 validity of group identifiers usable in the Group directive.
670 *) Various --enable-so options have been fixed: --enable-so is
671 treated as "static"; explicit --enable-so=shared issues an error;
672 and explicit --enable-so fails with error on systems without
673 APR_HAS_DSO. [Aaron Bannert]
675 *) Fix a segfault in the core input filter when the client socket
676 gets disconnected unexpectedly. [Cliff Woolley]
678 *) Fix the reporting for child processes that die. This removes
679 all of the non-portable W* macros from Apache.
680 [Jeff Trawick and Ryan Bloom]
682 *) Win32: Track and display "Parent Server Generation:" in
683 mod_status output. The generation will be bumped at
684 server graceful restart, when the child process exits
685 by hitting MaxRequestsPerChild or if the child
686 process exits abnormally. [Bill Stoddard]
688 *) Win32: Fix problem where MaxRequestsPerChild directive was
689 not being picked up in favor of the default. Enable
690 the parent to start up a new child process immediately upon
691 the old child starting shutdown.
694 *) Fix some bungling of the remote port in rfc1413.c so that
695 IdentityCheck retrieves the proper user id instead of failing
696 and thus always returning "nobody."
697 [Dick Streefland <Dick.Streefland@xs4all.nl>]
699 *) Introduced thread saftey for mod_rewrite's internal cache.
700 [Brian Pane <bpane@pacbell.net>]
702 *) Simplified mod_env's directives to behave as most directives are
703 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
704 directive following that UnsetEnv within the same container.
705 Also provides a runtime startup warning if a PassEnv configured
706 environment value is undefined. [William Rowe]
708 *) The worker MPM is now completely ported to APR's new lock API. It
709 uses native APR types for thread mutexes, cross-process mutexes,
710 and condition variables. [Aaron Bannert]
712 *) Sync up documentation to remove all references to the now deprecated
713 Port directive. [Justin Erenkrantz]
715 *) Moved all ldap modules from the core to httpd-ldap sub-project
718 *) Exit when we can't listen on any of the configured ports. This
719 is the same behavior as 1.3, and it avoids having the MPMs to
720 deal with bogus ap_listen_rec structures. [Jeff Trawick]
722 *) Cleanup the proxy code that creates a request to the origin
723 server. This change adds an optional hook, which allows modules
724 to gain control while the request is created if the proxy module
725 is loaded. The purpose of this hook is to allow modules to add
726 input and/or output filters to the request to the origin. While
727 I was at it, I made the core use this hook, so that proxy request
728 creation uses some of the code from the core. This can still be
729 greatly improved, but this is a good start. [Ryan Bloom]
731 Changes with Apache 2.0.26
733 *) Port the MaxClients changes from the worker MPM to the threaded
736 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
737 with the new input filtering system. [Justin Erenkrantz]
739 *) Introduce the MultiviewsMatch directive, to allow the operator
740 to be flexible in recognizing Handlers and Filters filename
741 extensions as part of the Multiviews matching logic, strict with
742 MultiviewsMatch NegotiatedOnly to accept only filename extentions
743 that designate negotiated parameters, (content type, charset, etc.)
744 or MultiviewsAll for the 1.3 behavior of matching any files, even
745 if they have unregistered extensions. [William Rowe]
747 *) Fixed the configure script to add a LoadModule directive to
748 the default httpd.conf for any module that was compiled
749 as a DSO. [Aaron Bannert <aaron@clove.org>]
751 *) rewrite mod_ssl input filtering to work with the new input filtering
752 system. [Justin Erenkrantz]
754 *) prefork: Don't segfault when we are able to listen on some but
755 not all of the configured ports. [Jeff Trawick]
757 *) Build mod_so even if no core modules are built shared.
758 [Aaron Bannert <aaron@clove.org>]
760 *) Introduce ap_directory_walk rewrite (with further optimizations
761 required) to adapt to the ap_process_request_internal() changes.
762 Optimized so subrequests and redirects now reuse previous section
763 merges, until we mismatch with the original directory_walk, and
764 precomputed r->finfo results will cause directory_walk to skip
765 the most expensive phases of the function. [William Rowe]
767 *) Allow ApacheMonitor to connect to and control Apache on other
768 WinNT/2K machines. [Mladen Turk <mturk@mappingsoft.com>]
770 *) Remove the Port directive. In it's place, the Listen directive
771 is now a required directive, which tells Apache what port to
772 listen on. The ServerName directive has also been extended
773 to accept an optional port. If the port is specified to the
774 ServerName, the server will report that port whenever it
775 reports the port that it is listening on. This change was
776 made to ease configuration errors that stem from having a Port
777 directive, and a Listen directive. In that situation, the server
778 would only listen to the port specified by the Listen command,
779 which caused a lot of confusion to users. [Ryan Bloom]
781 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
782 build, as loadable modules. [William Rowe]
784 *) Fix --enable-mods-shared processing. If most is specified,
785 then all modules that can be compiled as shared modules are.
786 [Aaron Bannert <aaron@clove.org>]
788 *) Update the mime.types file to map video/vnd.mpegurl to mxu
789 and add commonly used audio/x-mpegurl for m3u extensions.
790 [Heiko Recktenwald <uzs106@uni-bonn.de>, Lars Eilebrecht]
792 *) Eliminate the depreciated r->content_language, in favor of the array
793 r->content_languages introduced many years ago. Module authors must
794 substantially overhaul their modules, so this needs to be upgraded
795 if the module still relied on backwards-brokeness. [William Rowe]
797 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
800 *) Rewrite the input filtering mechanisms to consolidate and reorganize
801 code. In short, core_input_filter does something now and
802 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
804 *) Update the Win32 build to re-absorb mod_proxy and family.
807 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
808 current SDK.) [William Rowe]
810 *) Some style changes to the code that does ProxyErrorOverride. Fixed
811 config merge behaviour. [Graham Leggett]
813 *) Allow support programs to be compiled against a static version
814 of libapr. This allows the smaller support programs to be
815 relocated. [Aaron Bannert <aaron@clove.org>]
817 *) Update the mime.types file to the registered media types as
818 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
820 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
821 number of clients that can connect at the same time, instead of
822 specifying the maximum number of child processes.
823 [Aaron Bannert <aaron@clove.org>]
825 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
826 be consistent with 1.3. [Justin Erenkrantz]
828 *) Cache apr_explode_localtime() value for 15 seconds.
829 [Brian Pane <bpane@pacbell.net>]
831 *) Fix mod_include to not return ETag or Last-Modified headers.
832 [Ian Holsman <ianh@cnet.com>]
834 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron@clove.org>]
836 *) Eliminate the wasteful run-time conversion of method names from strings
837 to numbers in places where the methods are known at compile time.
838 [Brian Pane <bpane@pacbell.net>]
840 *) Turn the worker MPM's queue into a LIFO. This may
841 improve cache-hit performance under some conditions.
842 [Aaron Bannert <aaron@clove.org>]
844 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
845 support it. [Justin Erenkrantz]
847 *) Cleanup the worker MPM. We no longer re-use transaction
848 pools. This incurs less overhead than shuffling the pools
849 around so that they can be re-used. Remove one of the
850 queue's condition variables. We just redefined the API to
851 state that you can't try to add more stuff than you allocated
852 segments for. [Aaron Bannert <aaron@clove.org>]
854 *) Fix SSL VPATH builds [Cody Sherr <csherr@covalent.net>]
856 *) Fixed persistent connections when a request contains a body.
859 *) mod_dav uses a new API to speak to the backend provider for dead
860 property management. [Greg Stein]
862 *) Remove the Win32 script-processing exception from mod_cgi, and
863 roll build_command_line/build_argv_list into a unified, overrideable
864 ap_cgi_build_command optional function. [William Rowe]
866 *) Rewrite find_start_sequence to use a better search algorithm
867 to find the start tag. [Justin Erenkrantz]
869 *) Fix a seg fault in mod_include. When we are generating an
870 internal redirect, we must set r->uri to "", not a bogus
871 string, and not NULL. [Ryan Bloom]
873 *) Optimized location_walk, so subrequests, redirects and second passes
874 now reuse previous section merges on a <Location > by <Location >
875 basis, until we mismatch with the original location_walk.
878 *) Back out the 1.45 change to util_script.c. This change made
879 us set the environment variable REQUEST_URI to the redirected
880 URI, instead of the originally requested URI.
881 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
883 *) Make mod_include do lazy evaluation of potentially expensive to
884 compute variables. [Brian Pane <bpane@pacbell.net>]
886 *) Fix logging of bytes sent for HEAD requests. %b and %B should
887 log either - or 0, before this patch, they were both logging
888 the file size. [Taketo Kabe <kabe@sra-tohoku.co.jp>]
890 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
891 than per character. [Brian Pane <bpane@pacbell.net>]
893 *) Normalize the primary request, redirects and sub-requests to
894 run the same ap_process_request_internal for consistency in
895 robustness, behavior and security. [William Rowe]
897 *) Fix a segfault with mod_include when r->path_info is not set
898 (which is the case with mod_proxy). [Ian Holsman <ianh@cnet.com>]
900 *) Add -X functionality back. This indicates to all MPMs and any other
901 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
903 *) Some initial support for the cygwin platform [prefork only].
904 This is not to be confused with support for the WinNT/Win32
905 platform, which is the recommended configuration for native
906 Win32 users. The cygwin platform support is recommended for
907 cygwin platform users. [Stipe Tolj <tolj@wapme-systems.de>]
909 *) Changed syntax of Set{Input|Output}Filter. The list of filters
910 must be semicolon delimited (if more than one filter is given.)
911 The Set{Input|Output}Filter directive now overrides a parent
912 container's directive (e.g. SetInputFilter in <Directory /web/foo>
913 will override any SetInputFilter directive in <Directory /web>.)
914 This new syntax is more consistent with Add{Input|Output}Filter
915 directives defined in mod_mime. Also cures a bug in prior releases
916 where the Set{Input|Output}Filter directive would corrupt the
917 global configuration if the multiple directives were nested.
920 *) Cured what's ailed mime for quite some time. If an AddSomething
921 was given in the configuration (Language, Charset, Handler or
922 Encoding) Apache would set the content type as given by AddType,
923 but refused to check the mime.types file if AddType wasn't given
924 for that specific extension. Setting the AddHandler for .html
925 without setting the AddType text/html html would cause Apache to
926 use the default content type. [William Rowe]
928 *) Added some bulletproofing to memory allocation in the LDAP cache
929 code. [Graham Leggett]
931 Changes with Apache 2.0.25
933 *) Move the installed /manual directory out of the /htdocs/ tree, so
934 that it can be kept more independently from the remaining document
935 root. The "Alias /manual ..." already allowed for easy projection
936 into existing private document trees. [Martin Kraemer]
938 *) Add specified user attributes to the environment when using
939 mod_auth_ldap. This allows you to use mod_include to embed specified
940 user attributes in a page like so:
941 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
944 *) Fix a performance problem with the worker MPM. We now create
945 transaction pools once, and re-use them for each connection.
946 [Aaron Bannert <aaron@clove.org>]
948 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
949 of a 'handler' or 'filter', so that any filename extension that does
950 not contribute to the negotiated metadata can't be served without
951 an explicit request. E.g., if the .Z extension is associated with
952 an unzip filter, the user request somefile.Z.html, mod_negotiation
953 won't serve it. It can serve somefile.Z.html when somefile.Z is
954 requested, since the .Z extension is explictly requested, if the
955 .html extension is associated with ContentType text/html.
958 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
959 and corresponding AddOutputFilter syntax, to insert one or more
960 filters by mod_mime filename extension processing.
963 *) Fix a growing connection pool in core_output_filter() for
964 keepalive requests. [Jeff Trawick]
966 *) Moved split_and_pass_pretag_buckets back to being a
967 macro at Ryans's request. Removed the return from it
968 by setting and returning a return code instead. Updated
969 the code to check the return code from the macro and
970 do the right thing. [Paul J. Reder]
972 *) Fix a segfault when a numeric value was received for Host:.
975 *) Add a function ap_remove_input_filter. This is to match
976 up with ap_remove_output_filter. [Ryan Bloom]
978 *) Clean up location_walk, so that this step performs a minimum
979 amount of redundant effort (it must be run twice, but it will no
980 longer reparse all <Location > blocks when the request uri
981 hadn't changed.) [William Rowe]
983 *) Eliminate proxy: (and all other 'special') processing from the
984 ap_directory_walk() phase. Modules that want to use special
985 walk logic should refer to the mod_proxy map_to_location example,
986 with it's proxy_walk and proxysection implementation. This makes
987 either directory_walk flavor much more legible, since that phase
988 only runs against real <Directory > blocks.
991 *) Fix a security problem in mod_include which would allow
992 an SSI document to be passed to the client unparsed.
993 [Cliff Woolley, Brian Pane]
995 *) Introduce the map_to_storage hook, which allows modules to bypass
996 the directory_walk and file_walk for non-file requests. TRACE
997 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
998 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
1001 *) Add the ability for mod_include to add the INCLUDES filter
1002 if the file is configured for the server-parsed handler.
1003 This makes the configuration for .shtml files much easier
1004 to understand, and allows mod_include to honor Apache 1.3
1005 config files. Based on Doug MacEachern's patch to PHP
1006 to do the same thing. [Ryan Bloom]
1008 *) force OpenSSL to ignore process local-caching and to always
1009 get/set/delete sessions using mod_ssl's callbacks
1010 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
1011 Geoff Thorpe <geoff@geoffthorpe.net>]
1013 *) Make the worker MPM shutdown and restart cleanly. This also
1014 cleans up some race conditions, and gets the worker using
1015 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
1017 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
1019 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
1021 *) Fix for mod_include. Ryan's patch to check error
1022 codes put a return in the wrong place. Also, the
1023 include handler return code wasn't being checked.
1024 I don't like macros with returns, so I converted
1025 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
1026 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1028 *) fix segv in mod_mime if no AddTypes are configured
1029 [John Sterling <sterling@covalent.net>]
1031 *) Enable ssl client authentication at SSL_accept time
1032 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
1034 *) Fix a segfault in mod_include when the original request has no
1035 associated filename (e.g., we're filtering the error document for
1036 a bad URI). [Jeff Trawick]
1038 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
1040 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
1041 of httpd is started and shuts down due to socket conflict. Moving the
1042 call to ap_log_pid solves the problem.
1044 *) Changed the late-1.3 log_config substitution %c to %X, to log the
1045 status of the closed connection, as it conflicts with the far more
1046 common, historical ssl logging directive %...{var}c. [William Rowe]
1048 *) Added the common error/ tree to the build/install targets
1049 (similar to the common icons/ tree) for the multi-language error
1050 messages that Lars committed earlier. [William Rowe]
1052 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
1054 *) Added a default commented-out mod_ldap and mod_auth_ldap
1055 configuration to httpd-std.conf and httpd-win.conf
1058 *) Added documentation for mod_ldap and mod_auth_ldap.
1061 *) Enabled negative caching on attribute comparisons in the LDAP cache.
1062 Fixed a problem where the default cache TTL was set in milliseconds
1063 not microseconds causing the cache to time out almost immediately.
1066 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
1067 module code to follow APR. [Graham Leggett]
1069 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
1070 cleaned up when the connection pool pool is cleaned up.
1073 *) Fix a minor issue with Jeff Trawick's mod_include
1074 patch. Without this patch, the code will just allocate
1075 more bytes in get_combined_directive than are needed.
1078 *) Added the LDAP authentication module mod_auth_ldap.
1079 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
1081 *) Added the LDAP cache and connection pooling module mod_ldap.
1082 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
1084 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
1085 by allowing a module to disable itself if its prerequisites are not
1086 met. [Justin Erenkrantz]
1088 Changes with Apache 2.0.24
1090 *) Fix a couple of issues in mod_include when the tag appeared at
1091 offsets near 8192 in the file being parsed. [Jeff Trawick]
1093 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
1094 reached. [Jeff Trawick]
1096 *) Numerous improvements to the Win32 build system. Introduced command line
1097 builds without requiring .mak files for MSVC 6.0 and later versions.
1098 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
1101 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
1102 reporting of uninstalled services and other error conditions, and changed the
1103 default service name to Apache2. [William Rowe]
1105 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
1106 compatibility with existing Apache 1.3 Win32 Apache management utilites.
1107 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
1109 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
1110 [William Rowe, Greg Ames]
1112 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
1113 and RemoveCharset directives. [William Rowe]
1115 *) The Unix MPMs other than perchild now allow child server
1116 processes to use the accept mutex when starting as root and
1117 using SysV sems for the accept mutex. Previously, this
1118 combination would lead to fatal errors in the child server
1119 processes. perchild can't use SysV sems because of security
1120 issues. [Jeff Trawick, Greg Ames]
1122 *) Added Win32 revision stamp resources to all http binaries
1123 (including modules/ and support/ tools.) PR7322 [William Rowe]
1125 *) Fix ap_rvprintf to support more than 4K of data at one time.
1126 [Cody Sherr <csherr@covalent.net>]
1128 *) We have always used the obsolete/deprecated Netscape syntax
1129 for our tracking cookies; now the CookieStyle directive
1130 allows the Webmaster to choose the Netscape, RFC2109, or
1131 RFC2965 format. The new CookieDomain directive allows the
1132 setting of the cookie's Domain= attribute, too. PR #s 5006,
1133 5023, 5920, 6140 [Ken Coar]
1135 *) Tweak server/Makefile so that the rules for generating exports.c
1136 are compatible with make utilities which don't expand wildcards
1137 in a dependency list (e.g., OS/390 make, certain levels of GNU
1138 make). [Jeff Trawick]
1140 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
1142 *) Begin to sanitize the MPM configuration directives. Now, all
1143 MPMs use the same functions for all common MPM directives. This
1144 should make it easier to catch all bugs in these directives once.
1145 [Cody Sherr <csherr@covalent.net>]
1147 *) Close a major resource leak. Every time we had issued a
1148 graceful restart, we leaked a socket descriptor.
1151 *) Fix a problem with the new method code. We need to cast
1152 the 1 to an apr_int64_t or it will be treated as a 32-bit
1153 integer, and it will wrap after being shifted 32 times.
1154 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
1156 *) Fix a bug in mod_expires. Previous to this patch, if you
1157 told mod_expires to add 604800 seconds to the last-modified
1158 time, it actually added 604800 usec's to the last-modified time,
1159 so that when looking at the response it looked like nothing
1160 had been done. The root of the problem was that we always compute
1161 time in usec's, but we ask users to input sec's. This means we
1162 need to convert to usec's before using those values.
1165 *) The worker MPM now handles shutdown and restart requests. It
1166 definitely isn't perfect, but we do stop the servers correctly.
1167 The biggest problem right now is that SIGHUP causes the server to
1168 just die. [Ryan Bloom]
1170 Changes with Apache 2.0.23
1172 *) Use the prefork MPM by default on Unix. [various]
1174 *) Added a systray icon monitor application for Win32.
1175 [Mladen Turk <mturk@mappingsoft.com>]
1177 *) mod_rewrite: Fix the line ending on some non-Unix systems for
1178 messages written to the rewrite log.
1179 [Richard Labennett <rlabenn@us.ibm.com>]
1181 *) All mod_autoindex query parsing is now quietly quashed with the
1182 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
1183 still drops the column sort <a href>'s for the column headers, but
1184 IgnoreClient is required to ignore these Query options entirely.
1187 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
1188 to allow the client to select plain, FancyIndexing or HTMLTable
1189 formatting, V=[0|1] to inhibit or enable version sorting, and
1190 P=pattern to return only specific files. The old Query Arguments
1191 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
1192 as before), and O=A|D for ordering ascending or descending.
1195 *) Fixed an error in mod_include's directive parsing routines which
1196 caused #if, #elif, and #else expressions containing backslashes
1197 to be improperly evaluated. [Cliff Woolley]
1199 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
1200 drop the icon column, SuppressRules to drop the <hr> elements,
1201 and HTMLTable to create rudimentary HTML table listings (implies
1202 FancyIndexing). [William Rowe]
1204 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
1205 from Apache 1.3.15. This is needed for two reasons, first, given
1206 multiple machines within a server farm, ETags and Last-Modified
1207 stamps won't correspond from machine to machine, and second, many
1208 Unixes don't capture changes to the date or time stamp of existing
1209 files, since these don't modify the dirent itself. [William Rowe]
1211 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
1212 and DirectoryWidth options from Apache 1.3.10.
1213 [William Rowe, Ken Coar]
1215 *) Eliminated FancyIndexing directive, deprecated early in Apache
1216 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
1218 *) mod_autoindex now excludes any file names that would result in
1219 an error, other than a success or redirect. Also optimized
1220 the parent directory, always included except in the URI '/'.
1223 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
1224 negotiated index pages, and prevent the server from defaulting
1225 to an autoindex of the directory. mod_negotiation will now die
1226 with a 500 Internal Error if it could match some filenames
1227 (e.g. for mod_dir) but none can be served. mod_negotation now
1228 refuses to serve any file with an extention that mod_mime doesn't
1229 recognize, and wasn't part of the request. [William Rowe]
1231 *) Eliminate mod_cgi's handling of .exe files without the .exe file
1232 extension. This is already handled by multiviews, if the admin
1233 wishes to AddHandler .exe or define a content type handler and
1234 associate .exe files with that content type. Multiviews must be
1235 enabled to allow these to be served. [William Rowe]
1237 *) Speed up the server's response to a spike in incoming workload
1238 or restarts by assigning empty scoreboard slots to new processes
1239 when they are available. [Greg Ames]
1241 *) Add a handler to mod_includes.c. This handler is designed to
1242 implement the XbitHack directive. This can't be done with a
1243 fixup, because we need to check the content-type, which is
1244 only available in the handler phase. [Ryan Bloom]
1246 *) Make the includes filter check return codes from filters lower in
1247 the filter chain. If a lower level filter returns an error, then
1248 the request needs to stop immediately. This allows mod_include to
1249 stop parsing data once a lower filter recognizes an error.
1252 *) Add the ability to extend the methods that Apache understands
1253 and have those methods <limit>able in the httpd.conf. It uses
1254 the same bit mask/shifted offset as the original HTTP methods
1255 such as M_GET or M_POST, but expands the total bits from an int to
1256 an ap_int64_t to handle more bits for new request methods than
1257 an int provides. [Cody Sherr <csherr@covalent.net>]
1259 *) Fix broken mod_mime behavior in merging its arguments. Possible
1260 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
1262 *) Solve many mod_ssl porting issues (too many to detail) with
1263 help from the whole team, but most notably [Ralf S. Engelschall,
1264 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
1265 Doug MacEachern, William Rowe, Cliff Woolley]
1267 *) More stall fixes for the threaded & worker mpm's.
1268 Make mod_status output more accurate. Don't
1269 count workers in processes which aren't actively
1270 serving requests. [Greg Ames]
1272 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
1274 *) Add a single listener/multiple worker MPM. This MPM is
1275 definately not fully correct, but it allows us to solve many
1276 of the problems that exist in the threaded MPM. This is a
1277 modified version of the threaded MPM. [Ryan Bloom]
1279 *) Improve content generation throughout Apache, providing closer
1280 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
1281 Transitional specifications. [William Rowe]
1283 Changes with Apache 2.0.22
1285 *) Fix a problem where the threaded MPM stalls after restarts or
1286 segfaults. Also prevent multiple active processes from using
1287 the same scoreboard slot. [Greg Ames]
1289 *) Apache/Win32 now fills in the service description with Apache's
1290 server version string, including loaded and advertised modules.
1293 *) Improved support for the Win32 build, to recover gracefully from
1294 missing apr or apr-util directories or the awk interpreter,
1295 create the proper cgi-bin examples, including a test-cgi.bat, and
1296 fix the perl shebang line for printenv.pl, when installing from
1297 the build environment. [William Rowe]
1299 *) Fix a segfault in threaded.c caused by passing uninitialized
1300 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
1302 *) Use new APR number conversion functions to reduce CPU consumption
1303 when setting the content length, and in mod_log_config.
1306 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
1307 where HEAD response headers were being repeated twice for
1308 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
1309 problem in the http_header filter was exposed by the recent rewrite
1310 of the content_length filter. [Taketo Kabe, Bill Stoddard]
1312 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
1313 restarts. A garbage pointer to a vhost's server_rec from the
1314 previous generation was being left around under certain
1315 conditions. [Greg Ames]
1317 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
1318 used to appear as '(none', without the closing paren.
1319 [Günter Knauf <eflash@gmx.net>]
1321 *) Improve the exports generating awk script. In the past, we had
1322 work around problems in the awk script by avoiding some #if and
1323 #ifdefs. This has bitten us many times in generating the exports.c
1324 file. This improvement allows corrects the header file parsing.
1325 [Sander Striker <striker@apache.org>]
1327 Changes with Apache 2.0.21
1329 *) Resolve the Win32 htpasswd bug, where a file that existed would be
1330 overwritten, regardless of the -c flag.
1331 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
1333 *) Introduce connection sub-pools into ab. Truncating the lifetime
1334 of these allocations means that ab no longer perpetually grows
1335 its working set, running out of memory on large request attempts.
1338 *) Make scoreboard creation a hook. This allows management
1339 modules to have access to the scoreboard at the time that it is
1340 created, and at every restart request.
1341 [Cody Sherr <csherr@covalent.net>]
1343 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
1344 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
1345 daemon index actually used in the scoreboard. I also
1346 updated the pertinent calls. [Paul J. Reder]
1348 *) Win32: Prevent listening sockets from being inherited by
1349 the Apache child process, CGI scripts, rotatelog process
1350 etc. If the Apache child process segfaults, any processes
1351 that the child started are not reaped. Prior to this fix,
1352 these processes inherited the listening sockets which sometimes
1353 prevented the restarted Apache child process from accepting
1354 connections (ie, the server would hang).
1357 *) Provide vhost and request strings when ExtendedStatus is on.
1360 *) Fix some issues with the pod and prefork: check the pod *after*
1361 processing a connection so that a server processing a time-
1362 consuming request bails out as soon as practical; when the
1363 parent process wakes up a server process via connect(), use an
1364 APR timeout on the connect() so that we don't hang for a long
1365 time if there aren't server processes around to do accept().
1366 [Jeff Trawick, Greg Ames]
1368 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
1369 spends a lot of time in apr_table_get calls. Using the default
1370 httpd.conf, the tables for languages and charsets are somewhat
1371 large, so the time spent scanning them on each request is
1372 significant. Replacing the tables with hash tables provides
1373 a nice speedup. [Brian Pane <bpane@pacbell.net>]
1375 *) Add two functions to allow modules to access random parts of the
1376 scoreboard. This allows modules compiled for one MPM to access the
1377 scoreboard, even if it the server was compiled for another MPM.
1378 [Harrie Hazewinkel <harrie@covalent.net>]
1380 Changes with Apache 2.0.20
1382 *) Fix problem in content-length filter where the filter would
1383 buffer all the output from a CGI before sending any bytes
1384 down the filter stack to the network. This problem would cause
1385 significant memory consumption if the CGIs generated
1386 lots of bytes. [Bill Stoddard]
1388 *) Get non-blocking CGI pipe reads working with the bucket brigades.
1391 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
1394 *) Fix a bug in the threaded MPM that would cause it to kill off all
1395 workers immediately after starting if the number of workers started
1396 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
1398 Changes with Apache 2.0.19
1400 *) Fix problem with threaded MPM. The problem was that if each child
1401 process was busy serving a single long-lived request and the server
1402 was sent a graceful restart signal, the server would stop serving
1403 requests. This would happen because each child process would wait to
1404 die until the last thread was done, and the parent wouldn't spawn any
1405 new children until a process died. Now, the parent looks at the fact
1406 that the children are dying gracefully, and starts new children.
1407 Those new children only start enough threads to compliment the number
1408 of threads in the other child process that shares the same spot in
1409 the scoreboard. In this way, we make sure to never go over
1410 MaxClients. [Ryan Bloom]
1412 *) modified mod_negotiation and mod_autoindex to speed up by almost a
1413 factor of two on apr_dir_read()-enhanced platforms, such as Win32
1414 and OS2, by calling ap_sub_request_lookup_dirent() with the results
1415 already provided by apr_dir_read(). [William Rowe]
1417 *) mod_file_cache is now more robust to filtering and serves requests
1418 slightly more efficiently. [Cliff Woolley]
1420 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
1421 Module was calling ap_rwrite() followed by ap_rflush() but the
1422 served content was not being displayed in the browser. Inspection
1423 of the output stream revealed that the first data chunk was
1424 missing the trailing CRLF required by the RFC. [Bill Stoddard]
1426 *) apxs no longer generates ap_send_http_header() in the example handler
1428 *) Fix an ab problem which could cause a divide-by-zero exception
1429 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
1430 [Ian Holsman <ianh@cnet.com>]
1432 *) Solve case-insensitive platforms' confusion about negotiated
1433 filenames, allowing files of differnt case to match in choosing
1434 the document to serve. [William Rowe]
1436 *) Fix brokenness when ThreadsPerChild is higher than the built-in
1437 limit. We left ap_threads_per_child at the higher value which
1438 led to segfaults when doing certain scoreboard operations.
1441 *) Fix seg faults and/or missing output from mod_include. The
1442 default_handler was using the subrequest pool for files and
1443 MMAPs, even though the associated APR structures typically
1444 live longer than the subrequest. [Greg Ames]
1446 *) Extend mod_setenvif to support specifying regular expressions
1447 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
1448 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
1449 will cause HAVE_TS to be set if any of the request headers begins
1450 with "TS" and has a value that begins with any character in the
1451 set [a-z]. [Bill Stoddard]
1453 *) httpd children now re-bind themselves to a random CPU on
1454 multiprocessor systems on AIX via bindprocessor() in 2.0.
1455 [Victor J. Orlikowski]
1457 *) Fix htdigest. It would go into a loop in getline when adding
1458 a second user. [Bill Stoddard]
1460 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
1462 *) Automatically generate httpd.exp for AIX.
1463 DSOs now work again on AIX in 2.0
1464 [Victor J. Orlikowski]
1466 *) Add a new request hook, error_log. This phase allows modules
1467 to act on the error log string _after_ it has been written
1468 to the error log. The goal for this hook is to allow monitoring
1469 modules to send the error string to the monitoring agent.
1472 *) Modify mod_echo to make it use filters for input and output.
1473 [Ryan Morgan <rmorgan@covalent.net>]
1475 *) Extend mod_headers to support conditional driven Header
1476 add, append and set. Use SetEnvIf to set an envar and conditionally
1477 add/append/set headers based on this envar thusly:
1479 SetEnvIf TSMyHeader value HAVE_TSMyHeader
1480 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
1482 If the request contains header "TSMyHeader: value" then header
1483 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
1486 *) Extend mod_headers to support using format specifiers on Header
1487 add, append and set header values. Two format specifiers are supported:
1489 %t - reports, in UTC microseconds since the epoch, when the
1490 request was received.
1492 %D - reports the time, in microseconds, between when the request was
1493 received and the response sent.
1496 Header add MyHeader "This request served in %D microseconds. %t"
1498 results in a header being added to the response that looks like this:
1500 MyHeader: This request served in D=5438 microseconds. t=991424704447256
1504 *) Fix reset_filter(). We need to be careful how we remove filters.
1505 If we set r->output_filters to NULL, we also have to reset the
1506 connection's filters. [John Sterling]
1508 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
1510 *) Add a check to ap_die() to make sure the filter stack is sane and
1511 contains the correct basic filters when an error occurs. This fixes
1512 a problem where headers are not being sent on error. [John Sterling]
1514 *) New Header directive 'echo' option. "Header echo regex" will
1515 cause any headers received on the request that match regex to be
1516 echoed to (included in) the response headers.
1519 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
1520 This prevented the inclusion of apr_compat.h. PR #7773
1521 [Oleg Broytmann <phd@phd.pp.ru>]
1523 *) Moved util_uri to the apr-util library. This required a bunch of
1524 apr_name changes for the uri utility functions. [Justin Erenkrantz]
1526 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
1527 insert_filter phase so that other filters are not bypassed by default.
1530 *) Reimplement mod_headers as an output filter. mod_headers can now
1531 add custom headers to inbound requests using the RequestHeader directive
1532 and to responses using the same old Header directive. [Graham Leggett]
1534 Changes with Apache 2.0.18
1536 *) Fix command-line processing so that if a bad argument is specified
1537 Apache will exit. [Jeff Trawick]
1539 *) Change the make targets and rules to be consistent in all of the
1540 Apache-owned source trees. [Roy Fielding]
1542 *) Fix processing of the TRACE method. Previously we passed bogus
1543 parms to form_header_field() and it overlaid some vhost structures,
1544 resulting in a segfault in check_hostalias().
1545 [Greg Ames, Jeff Trawick]
1547 *) Win32: Add support for reliable piped logs. If the logging process
1548 goes down, Apache will automatically restart it. This function has
1549 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
1552 *) Do not start piped log processes during the config file
1553 preflight. This change also circumvents a problem on
1554 Windows where the rotatelog processes created during preflight
1555 was not getting cleaned up properly.
1558 *) add "Request Phase Participation" info to mod_info
1561 *) Make first phase changes to the scoreboard data structures in
1562 preparation for the rewriting of the scoreboard per my posted
1563 design notes. [Paul J. Reder]
1565 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
1566 and apr-util, allow it to be overridden by the configure command-line
1567 (default="--silent") and introduce LT_LDFLAGS to replace what we were
1568 formerly abusing as LTFLAGS. [Roy Fielding]
1570 *) Clean up the reporting of incorrect closing container tags.
1571 [Barrie Slaymaker <barries@slaysys.com>]
1573 *) Simplify the configure process by moving all libtool stuff to APR
1574 and moving hints.m4 inline. [Roy Fielding]
1576 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
1577 of functions used by mod_proxy for export in the DLL
1578 [Ian Holsman <IanH@cnet.com>]
1580 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
1581 request body from its stdin but no reqest body is being written to
1582 the cgi. [Jeff Trawick]
1584 *) mod_log_config: %c connection status incorrectly logged
1585 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
1588 *) Get mod_cern_meta working under Windows
1591 *) Create Files, and thus MMAPs, out of the request pool, not the
1592 connection pool. This solves a small resource leak that had us
1593 not closing files until a connection was closed. In order to do
1594 this, at the end of the core_output_filter, we loop through the
1595 brigade and convert any data we have into a single HEAP bucket
1596 that we know will survive clearing the request_rec.
1597 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
1600 *) Completely revamp configure so that it preserves the standard make
1601 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
1602 the configure additions to EXTRA_* variables. Also, allow the user
1603 to specify NOTEST_* values for all of the above, which eliminates the
1604 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
1605 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
1606 avoid pointless duplications. Fix the order in which flags are given
1607 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
1608 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
1609 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
1610 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
1612 *) Get mod_tls to compile/work better on Windows. PR #7612
1613 [Bernhard Schrenk <b.schrenk@improx.com>]
1615 *) Fix shutdown/restart hangs in the threaded MPM.
1616 [Jeff Trawick, Greg Ames, Ryan Bloom]
1618 *) Removed the keptalive boolean from conn_rec because it is now only
1619 used by a single routine and can be replaced by a local variable.
1620 [Greg Stein, Ryan Bloom, Roy Fielding]
1622 *) Patch prefork to put enough of the signal processing back in so that
1623 signals are all handled properly now. The previous patch fixed the
1624 deadlock race condition, but broke the user directed signal handling.
1625 This fixes it to work the way it did before my previous prefork patch
1626 (primarily, SIGTERM is now working).
1628 *) Change how input filters decide how much data is returned to the
1629 higher filter. We used to use a field in the conn_rec, with this
1630 change, we use an argument to ap_get_brigade to determine how much
1631 data is retrieved. [Ryan Bloom]
1633 *) Fix seg fault at start-up introduced by Ryan's change to enable
1634 modules to specify their own logging tags. mod_log_config
1635 registers an optional function, ap_register_log_handler().
1636 ap_register_log_handler() was being called by http_core before
1637 the directive hash table was created. This patch creates the
1638 directive hash table before ap_register_log_handler() is
1639 registered as an optional function.
1640 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1642 *) Add ap_set_int_slot() function
1643 [John K. Sterling <sterling@covalent.net>]
1645 *) Under certain circumstances, Apache did not supply the
1646 right response headers when requiring authentication.
1647 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
1648 (This is a port of the change that went into Apache 1.3.19.)
1650 *) Allow modules to specify their own logging tags. This basically
1651 allows a module to tell mod_log_config that when %x is encountered
1652 a specific function should be called. Currently, x can be any single
1653 character. It may be more useful to make this a string at some point.
1656 Changes with Apache 2.0.17
1658 *) If a higher-level filter handles the the byterange aspects of a
1659 request, then the byterange filter should not try to redo the
1660 work. The most common case of this happening, is a byterange
1661 request going through the proxy, and the origin server handles
1662 the byterange request. The proxy should ignore it.
1663 [Graham Leggett <minfrin@sharp.fm>]
1665 *) Changed the threaded mpm to have child_main join to each of the
1666 worker threads to make sure the kids are all gone before child_main
1667 exits after a signal (cleanup from perform_idle_server_maintenance).
1668 This is an extension of Ryans recent commit to make the child_main
1671 *) Add more options to the ap_mpm_query function. This also allows MPMs to
1672 report if their threads are dynamic or static. Finally, this also
1673 implements a new API, ap_show_mpm, which returns the MPM that was
1674 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
1676 *) Do not install the binaries from the support directory twice.
1677 [jun-ichiro hagino <itojun@iijlab.net>]
1679 *) The ap_f* functions should flush data to the filter that is passed
1680 in, not the the filter after the one passed in.
1681 [Ryan Morgan <rmorgan@covalent.net>]
1683 *) Make ab work again by changing its native types to apr types and formats.
1684 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
1686 *) Move the byterange filter and all of the supporting functions back
1687 to the HTTP module. The byterange filter turned out to be very
1688 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
1690 *) Make clean, distclean, and extraclean consistently according to the
1691 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
1693 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
1694 This may have been causing problems stopping processes in the threaded
1697 *) Fix content-length in mod_negotiation to a long int representation.
1700 *) Remove BindAddress from the default config file.
1701 [giles@nemeton.com.au]
1703 *) Allow module authors to add a module to their Apache build using
1704 --with-module, without re-running buildconf. The syntax is:
1705 --with-module=module_type:/path/to/module.c
1706 The configure script will copy the module.c file to
1707 modules/module_type, and it will be added to the relevant Makefiles.
1708 currently, this only works for static modules. [Ryan Bloom]
1710 *) Changes required to make prefork clean up idle children properly.
1711 There was a window during which a starting worker deadlocks when
1712 an idle cleanup arrives before it completes init. Apache then keeps
1713 trying to cleanup the same deadlocked worker forever (until higher
1714 pids come along, but it still will never reduce below the deadlocked
1715 pid). Thus the number of children would not reduce to the correct
1716 idle level. [Paul J. Reder]
1718 Changes with Apache 2.0.16
1720 *) Change the default installation directory to /usr/local/apache2,
1721 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
1723 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
1726 *) Get MaxRequestsPerChild working with the Windows MPM.
1729 *) Make generic hooks to work, with mod_generic_hook_import/export
1730 experimental modules. [Ben Laurie, Will Rowe]
1732 *) Fix segfaults for configuration file syntax errors such as
1733 "<Directory>" followed by "</Directory" and
1734 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
1736 *) Cleanup the --enable-layout option of configure. This makes
1737 us use a consistent location for the config.layout file, and it
1738 makes configure more portable.
1739 [jun-ichiro hagino <itojun@iijlab.net>]
1741 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
1742 csv/gnuplot format, rudimentary ssl support and various other tweaks
1743 to make results more true to what is measured. The upshot of this it
1744 turns out that 'ab' has often underreported the true performance of
1745 apache. Often by a order of magnitude :-) See talk/paper of Sander
1746 Temme <sctemme@covalent.net> at April ApacheCon 2001 for details.
1747 [Dirk-Willem van Gulik]
1749 *) Clean up mod_cgid's temporary request pool. Besides fixing a
1750 storage leak this ensures that some unnecessary pipes are closed.
1753 *) Performance: Add quick_handler hook. This hook is called at the
1754 very beginning of the request processing before location_walk,
1755 translate_name, etc. This hook is useful for URI keyed content
1756 caches like Mike Abbott's Quick Shortcut Cache.
1759 *) top_module global variable renamed to ap_top_module [Perl]
1761 *) Move ap_set_last_modified to the core. This is a potentially
1762 controversial change, because this is kind of HTTP specific. However
1763 many protocols should be able to take advantage of this kind of
1764 information. I expect that headers will need one more layer of
1765 indirection for multi-protocol work, but this is a small step in
1766 the right direction. [Ryan Bloom]
1768 *) Enable mod_status by default. This matches what Apache 1.3 does.
1771 *) Add a ScriptSock directive to the default config file. This is
1772 only enabled when mod_cgid is used.
1773 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1775 Changes with Apache 2.0.15
1777 *) Untangled the buildconf script and eliminated the need for build's
1778 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
1779 libtool muck that is now under srclib/apr/build. [Roy Fielding]
1781 *) Win32: Don't accept more connections than we have worker threads
1785 *) Fix bug in the Unix threaded.c MPM that allowed child processes
1786 to fork() new child processes.
1789 *) Fix a major security problem with double-reverse lookup checking.
1790 Previously, a client connecting over IPv4 would not be matched
1791 properly when the server had an IPv6 listening socket. PR #7407
1792 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
1794 *) Change the way the beos MPM handles polling to allow it to stop and
1795 restart. Problem was the sockets being polled were being reset by
1796 the select call, so once it had accepted a connection it was no
1797 longer listening on the UDP socket we use for shutdown instructions.
1798 APR needs to be altered, patch on it's way. [David Reid]
1800 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
1801 on error exit from ap_getline(). Some other code got upset because
1802 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
1804 *) Handle ap_discard_request_body() being called more than once.
1805 [Greg Ames, Jeff Trawick]
1807 *) Get rid of an inadvertent close of file descriptor 2 in
1808 mod_mime_magic. [Greg Ames, Jeff Trawick]
1810 *) Add a hook, create_request. This hook allows modules to modify
1811 a request while it is being created. This hook is called for all
1812 request_rec's, main request, sub request, and internal redirect.
1813 When this hook is called, the the r->main, r->prev, r->next
1814 pointers have been set, so modules can determine what kind of
1815 request this is. [Ryan Bloom]
1817 *) Cleanup the build process a bit more. The Apache configure
1818 script no longer creates its own helper scripts, it just
1820 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1822 *) Stop the forced downgrade of the connection to HTTP/1.0 for
1823 proxy requests. [Graham Leggett]
1825 *) Avoid using sscanf to determine the HTTP protocol number in
1826 the common case because sscanf is a performance hog. From
1827 Mike Abbot's Accelerating Apache patch number 6.
1828 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
1830 *) Fix a security exposure in mod_access. Previously when IPv6
1831 listening sockets were used, allow/deny-from-IPv4-address rules
1832 were not evaluated properly (PR #7407). Also, add the ability to
1833 specify IPv6 address strings with optional prefix length on Allow
1834 and Deny. [Jeff Trawick]
1836 *) Enhance rotatelogs so that a UTC offset can be specified, and
1837 the logfile name can be formatted using strftime(3). (Brought
1838 forward from 1.3.) [Ken Coar]
1840 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
1841 DuplicateHandle on an IOCompletionPort (a practice which
1842 MS "discourages"). The new model does not rely on associating
1843 the completion port with the listening sockets, thus the
1844 completion port can be completely managed within the child
1845 process. A dedicated thread accepts connections off the network,
1846 then calls PostQueuedCompletionStatus() to wake up worker
1847 threads blocked on the completion port.
1850 *) Bring forward the --suexec-umask option which allows the
1851 builder to preset the umask for suexec processes. [Ken Coar]
1853 *) Add a -V flag to suexec, which causes it to display the
1854 compile-time settings with which it was built. (Only
1855 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
1857 *) Mod_include should always unset the content-length if the file is
1858 going to be passed through send_parsed_content. There is no to
1859 determine if the content will change before actually scanning the
1860 entire content. It is far safer to just remove the C-L as long
1861 as we are scanning it. [Ryan Bloom]
1863 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
1864 request and not Proxy-Authenticate.
1865 [Graham Leggett <minfrin@sharp.fm>]
1867 Changes with Apache 2.0.14
1869 *) Fix content-length computation. We ONLY compute a content-length if
1870 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
1871 or we already have all the data. [Ryan Bloom]
1873 *) Report unbounded containers in the config file. Previously, a typo
1874 in the </container> directive could result in the rest of the config
1875 file being silently ignored, with undesired defaults used.
1878 *) Make the old_write filter use the ap_f* functions for the buffering.
1881 *) Move more code from the http module into the core server. This
1882 is core code, basically the default handler, the default input
1883 and output filters, and all of the core configuration directives.
1884 All of this code is required in order for the server to work, with or
1885 without HTTP. The server is closer to working without the HTTP
1886 module, although there is still more to do. [Ryan Bloom]
1888 *) Fix a number of SGI compile warnings throughout the server. Fix some
1889 bad parameters to apr_bucket_read(). Fix a bad statement in
1890 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
1891 consistently; we were mixing apr_time_t and time_t in invalid ways
1892 before. In load_file(), call apr_dso_error() instead of
1893 apr_strerror() so that we get a more specific string on some platforms.
1894 PR #6980 [Jeff Trawick]
1896 *) Allow modules to query the MPM about it's execution profile. This
1897 query API can and should be extended in the future, but for now,
1898 max_daemons, and threading or forking is a very good start.
1899 [Jon Travis <jtravis@covalent.net>]
1901 *) Modify mod_include to send blocks of data no larger than 9k.
1902 Without this, mod_include will wait until the whole file is parsed,
1903 or the first tag is found to send any data to the client.
1904 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1906 *) Fix mod_info, so that <Directory> and <Location> directives are
1907 not displayed twice when displaying the current configuration.
1908 [Ryan Morgan <rmorgan@covalent.net>]
1910 *) Add config directives to override DEFAULT_ERROR_MSG and
1911 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
1912 [Dan Rench <drench@xnet.com>]
1914 *) Get mod_info building and loading on Win32. [William Rowe]
1916 *) Begin to move protocol independant functions out of mod_http. The goal
1917 is to have only functions that are HTTP specific in the http directory.
1920 Changes with Apache 2.0.13
1922 *) Don't assume that there will always be multiple calls to the byterange
1923 filter. It is possible that we will need to do byteranges with only
1924 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
1926 *) Move the error_bucket definition from the http module to the
1927 core server. Every protocol will need this ability, not just
1930 Changes with Apache 2.0.12
1932 *) Modify mod_file_cache to save pre-formatted strings for
1933 content-length and last-modified headers for performance.
1934 [Mike Abbot <mja@trudge.engr.sgi.com>]
1936 *) Namespace protect IOBUFSIZ since it is exposed in the API.
1937 [Jon Travis <jtravis@covalent.net>]
1939 *) Use "Basic" authentication instead of "basic" in ab, as the spec
1940 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
1942 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
1943 without ever filling it out. This fixes PR 7271.
1944 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
1945 Cliff Woolley <cliffwoolley@yahoo.com>]
1947 *) Add a couple of GCC attribute tags to printf style functions.
1948 [Jon Travis <jtravis@covalent.net>]
1950 *) Add the correct language tag for interoperation with the Taiwanese
1951 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
1953 *) Migrate the perchild MPM to use the new apr signal child, and
1954 APR thread functions. [Ryan Bloom]
1956 *) Close one copy of the CGI's stdout before creating the new process.
1957 The CGI will still have stdout, because we have already dup'ed it.
1958 This keeps Apache from waiting forever to send the results of a CGI
1959 process that has forked a long-lived child process.
1960 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1962 *) Remove the rest of the pthreads functions from the threaded MPM.
1963 This requires the APR support for a signal thread that was just
1966 *) Make mod_dir use a fixup for sending a redirect to the browser.
1967 Before this, we were using a handler, which doesn't make much
1968 sense, because the handler wasn't generating any data, it would
1969 either return a redirect error code, or DECLINED. This fits the
1970 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
1972 *) Make the threaded MPM use APR threads instead of pthreads.
1975 *) Get mod_tls to the point where it actually appears to work in all cases.
1978 *) implement --enable-modules and --enable-mods-shared for "all" and
1979 "most". [Greg Stein]
1981 *) Move the threaded MPM to use APR locks instead of pthread locks.
1984 *) Rename mpmt_pthread to threaded. This is more in line with the
1985 fact that mpmt_pthread shouldn't be using pthreads directly, and
1986 it is a smaller name that doesn't tie into anything.
1989 *) Rename the module structures so that the exported symbol matches
1990 the file name, and it is easier to automate the installation
1991 process (generating LoadModule directives from the module filenames).
1994 *) Remove the coalesce filter. With the ap_f* functions, this filter
1995 is no longer needed. [Ryan Bloom]
1997 Changes with Apache 2.0.11
1999 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
2000 added feature of allowing a uid/gid per child process. If no
2001 uid/gid is specified, then Perchild behaves exactly like dexter.
2004 *) Get perchild building again. [Ryan Bloom]
2006 *) Don't disable threads just because we are using the prefork MPM.
2007 If somebody wants to compile without threads, they must now add
2008 --disable-threads to the configure command line. [Ryan Bloom]
2010 *) Begin to move the calls to update_child_status into common code, so
2011 that each individual MPM does not need to update the scoreboard itself.
2014 *) Allow mod_tls to compile under Unix boxes where openssl has been
2015 installed to the system include files.
2016 [Gomez Henri <new-httpd@slib.fr>]
2018 *) Cleanup the mod_tls configure process. This should remove any need
2019 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
2020 configure doesn't check that yet. [Ryan Bloom]
2022 *) Add a very early prototype of SSL support (in mod_tls.c). It is
2023 vital that you read modules/tls/README before attempting to build
2026 *) Fix a potential seg fault on all platforms. David Reid fixed this
2027 on BEOS, but the problem could happen anywhere, so we don't want
2028 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
2030 *) Add new LogFormat directive, %D, to log time it takes to serve a
2031 request in microseconds. [Bill Stoddard]
2033 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
2034 SetOutputFilter. This corresponds nicely with the other Set
2035 directives, which operate on containers while the Add* directives
2036 tend to work directly on extensions. [Ryan Bloom]
2038 *) Cleanup the header handling a bit. This uses the apr_brigade_*
2039 functions for the buffering so that we don't need to compute
2040 the length of the headers before we actually create the header
2041 buffer. [Ryan Bloom]
2043 *) Allow filters to buffer data using the ap_f* functions. These have
2044 become macros that resolve directly to apr_brigade_*.
2047 *) Get the Unix MPM's to do a graceful restart again. If we are going
2048 to register a cleanup with ap_cleanup_scoreboard, then we have to
2049 kill the cleanup with the same function, and that function can't be
2050 static. [Ryan Bloom]
2052 *) Install all required header files. Without these, it was not
2053 possible to compile some modules outside of the server.
2056 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
2057 forward from 1.3 to 2.0, we missed a single line, which broke regex
2058 aliases. [Ryan Bloom]
2060 *) We have a poor abstraction in the protocol. This is a temporary
2061 hack to fix the bug, but it will need to be fixed for real. If
2062 we find an error while sending out a custom error response, we back
2063 up to the first non-OK request and send the data. Then, when we send
2064 the EOS from finalize_request_protocol, we go to the last request,
2065 to ensure that we aren't sending an EOS to a request that has already
2066 received one. Because the data is sent on a different request than
2067 the EOS, the error text never gets sent down the filter stack. This
2068 fixes the problem by finding the last request, and sending the data
2069 with that request. [Ryan Bloom]
2071 *) Make the server status page show the correct restart time, and
2072 thus the proper uptime. [Ryan Bloom]
2074 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
2075 should reduce the amount of duplicate code that is required to
2076 create CGI processes.
2077 [Paul J. Reder <rederpj@raleigh.ibm.com>]
2079 *) ap_new_connection() closes the socket and returns NULL if a socket
2080 call fails. Usually this is due to a connection which has been
2081 reset. [Jeff Trawick]
2083 *) Move the Apache version information out of httpd.h and into release.h.
2084 This is in preparation for the first tag with the new tag and release
2085 system. [Ryan Bloom]
2087 *) Begin restructuring scoreboard code to enable adding back in
2088 the ability to use IPC other than shared memory.
2089 Get mod_status working on Windows again. [Bill Stoddard]
2091 *) Make mod_status work with 2.0. This will work for prefork,
2092 mpmt_pthread, and dexter. [Ryan Bloom]
2094 *) Correct a typo in httpd.conf.
2095 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
2097 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
2099 *) Get the correct IP address if ServerName isn't set and we can't
2100 find a fully-qualified domain name at startup.
2101 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
2103 *) Make mod_cgid work with SuExec. [Ryan Bloom]
2105 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
2106 'extra' stat's for user/group since they should never occur, and now
2107 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
2108 volumes. [William Rowe]
2110 *) Adopt apr features to simplify mod_includes. This changes the
2111 behavior of the USER_NAME variable, unknown uid's are now reported
2112 as USER_NAME="<unknown>" rather than the old user#000 result.
2113 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
2115 *) Adopt apr features for simplifing mod_userdir, and accept the new
2116 Win32/OS2 exceptions without hiccuping. [William Rowe]
2118 *) Replace configure --with-optim option by using and saving the
2119 environment variable OPTIM instead. This is needed because configure
2120 options do not support multiple flags separated by spaces.
2123 *) Fix some byterange handling. If we get a byte range that looks like
2124 "-999999" where that is past the end of the file, we should return
2125 a PARTIAL CONTENT status code, and return the whole file as one big
2126 byterange. This matches the 1.3 handling now. [Ryan Bloom]
2128 *) Make the error bucket a real meta-data bucket. This means that the
2129 bucket length is 0, and a read returns NULL data. If one of these
2130 buckets is passed down after the headers are sent, this data will
2131 just be ignored. [Greg Stein]
2133 *) The prefork MPM wasn't killing child processes correctly if a restart
2134 signal was received while the process was serving a request. The child
2135 process would become the equivalent of a second parent process. If
2136 we break out of the accept loop, then we need to do die after cleaning
2137 up after ourselves. [Ryan Bloom]
2139 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
2140 restarts. [Ryan Bloom]
2142 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
2143 the most optimal APR_FINFO_wanted bits. This spares Win32 from
2144 performing very expensive owner, group and permission lookups
2145 and allows the server to function until these apr_finfo_t fields
2146 are implemented under Win32. [William Rowe]
2148 *) Support for typedsafe optional functions - that is functions exported by
2149 optional modules, which, therefore, may or may not be present, depending
2150 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
2151 for sample code. [Ben Laurie]
2153 *) filters can now report an HTTP error to the server. This is done
2154 by sending a brigade where the first bucket is an error_bucket.
2155 This bucket is a simple bucket that stores an HTTP error and
2156 a string. Currently the string is not used, but it may be needed
2157 to output an error log. The http_header_filter will find this
2158 bucket, and output the error text, and then return
2159 AP_FILTER_ERROR, which informs the server that the error web page
2160 has already been sent. [Ryan Bloom]
2162 *) If we get an error, then we should remove all filters except for
2163 those critical to serving a web page. This fixes a bug, where
2164 error pages were going through the byterange filter, even though
2165 that made no sense. [Ryan Bloom]
2167 *) Relax the syntax checking of Host: headers in order to support
2168 iDNS. PR#6635 [Tony Finch]
2170 *) Cleanup the byterange filter to use the apr_brigade_partition
2171 and apr_bucket_copy functions. This removes a lot of very messy
2172 code, and hopefully makes this filter more stable.
2175 *) Remove AddModule and ClearModuleList directives. Both of these
2176 directives were used to ensure that modules could be enabled
2177 in the correct order. That requirement is now gone, because
2178 we use hooks to ensure that modules are in the correct order.
2181 *) When SuExec is specified, we need to add it to the list of
2182 targets to be built. If we don't, then any changes to the
2183 configuration won't affect SuExec, unless 'make suexec' is
2184 specifically run. [Ryan Bloom]
2186 *) Cleaned out open_file from mod_file_cache, as apr now accepts
2187 the APR_XTHREAD argument to open a file for consumption by
2188 parallel threads on win32. [William Rowe]
2190 *) Correct a bug in determining when we follow symlinks. The code
2191 expected a stat -1 result, not an apr_status_t positive error.
2192 Also check if the APR_FINFO_USER fields are valid before we
2193 follow the link. [William Rowe]
2195 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
2196 mpm_common.c. These functions are only valid on some platforms,
2197 so they should not be in the main-line code. [Ryan Bloom]
2199 *) Remove ap_chdir_file(). This function is not thread-safe,
2200 and nobody is currently using it. [Ryan Bloom]
2202 *) Do not try to run make depend if there are no .c files in the
2203 current directory, doing so makes `make depend` fail.
2206 *) Update highperformance.conf to work with either prefork or
2207 pthreads mpms. [Greg Ames]
2209 *) Stop checking to see if this is a pipelined request if we know
2210 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
2211 This keeps us from making an extra read call when serving a 1.0
2212 request. [Ryan Bloom and Greg Stein]
2214 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
2215 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
2216 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
2218 *) Fix the RFC number mentioned when complaining about a missing
2219 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
2221 *) Fix an endless loop in ab which occurred when ab was posting
2222 and the server dropped the connection unexpectedly.
2225 *) Fix a segfault while handling request bodies in ap_http_filter().
2226 This problem has been seen with mod_dav usage as well as with
2227 requests where the body was just being discarded. [Jeff Trawick]
2229 *) Some adjustment on the handling and automatic setting (via
2230 hints.m4) of various compilation flags (eg: CFLAGS). Also,
2231 add the capability to specify flags (NOTEST_CFLAGS and
2232 NOTEST_LDFLAGS) which are used to compile Apache, but
2233 not used during the configuration process. Useful for
2234 flags like "-Werror". [Jim Jagielski]
2236 *) Stop using environment variables to force debug mode or
2237 no detach. We now use the -D command line argument to
2238 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
2239 [Greg Stein, Ryan Bloom]
2241 *) Change handlers to use hooks. [Ben Laurie]
2243 *) Stop returning copies of filenames from both apr_file_t and
2244 apr_dir_t. We pstrdup the filenames that we store in the
2245 actual structures, so we don't need to pstrdup the strings again.
2248 *) mod_cgi: Fix some problems where the wrong error value was being
2249 traced. [Jeff Trawick]
2251 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
2254 *) Add generic hooks. [Ben Laurie]
2256 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
2258 *) Fix a segfault caused by mod_ext_filter when the external filter
2259 program does not exist. [Jeff Trawick]
2261 *) Fix an output truncation error when on an HTTP >= 1.0 request an
2262 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
2263 was served through mod_charset_lite (or anything else that would
2264 create a transient bucket in this size range). ap_bucket_make_heap()
2265 silently failed (fixed), transient_setaside() discovered it, but
2266 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
2268 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
2269 is that some browsers send extra lines at the end of POST requests, and
2270 we don't want to delay sending data back to the user just because the
2271 browser isn't well behaved. [Ryan Bloom]
2273 *) Get SuEXEC working again. We can't send absolute paths to suExec
2274 because it refuses to execute those programs. SuEXEC also wasn't
2275 always recognizing configuration changes made using the autoconf
2278 *) Allow the buildconf process to find the config.m4 files in the correct
2279 order. Basically, we can now name config.m4 files as config\d\d.m4,
2280 and we will sort them correctly when inserting them into the build
2281 process. [Ryan Bloom]
2283 *) Get mod_cgid to use apr calls for creating the actual CGI process.
2284 This also allows mod_cgid to use ap_os_create_priviledged_process,
2285 thus allowing for SuExec execution from mod_cgid. Currently, we do
2286 not support everything that standard SuExec supports, but at least
2287 it works minimally now. [Ryan Bloom]
2289 *) Allow SuExec to be configured from the ./configure command line.
2292 *) Update some of the docs in README and INSTALL to reflect some of
2293 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
2295 *) If we get EAGAIN returned from the call to apr_sendfile, then we
2296 need to call sendfile again. This gets us serving large files
2297 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
2299 *) Get the support programs building cleanly again.
2300 [Cliff Woolley <cliffwoolley@yahoo.com>]
2302 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
2303 current directory logic now backs up over bin/ to determine the
2304 server root from the Apache.exe path.
2306 *) Apache/Win32 now follows the standard conventions of mod_foo.so
2307 loadable modules, dynamic libs are all named libfoo.dll, and the
2308 makefile.win populates the include, lib and libexec directories.
2310 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
2311 Apache gets IPv6 listening sockets by default. Additionally, the
2312 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
2313 numeric address strings (e.g., "Listen [fe80::1]:8080").
2316 *) Modify the install directory layout. Modules are now installed in
2317 modules/. Shared libraries should be installed in libraries/, but
2318 we don't have any of those on Unix yet. All install directories
2319 are modifyable at configure time. [Ryan Bloom]
2321 *) Install all header files in the same directory on Unix. [Ryan Bloom]
2323 *) Get the functions in server/linked into the server, regardless of
2324 which modules linked into the server. This uses the same hack
2325 for Apache that we use for APR and apr-util to ensure all of the
2326 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
2327 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
2328 the scripts a bit easier.
2331 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
2332 on the query, and remove IPv4 dependencies. [Jeff Trawick]
2334 *) Get all of the auth modules to the point that they will install and
2335 be loadable into the server. Our new build/install mechanism expects
2336 that all modules will have a common name format. The auth modules
2337 didn't use that format, so we didn't install them properly.
2340 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
2341 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
2343 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
2345 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
2346 after the end of the response. [Ryan Bloom]
2348 *) Get byterange requests working with responses that do not have a
2349 content-length. Because of the way byterange requests work, we have to
2350 have all of the data before we can actually do the byterange, so we
2351 can compute the content-length in the byterange filter.
2354 *) Get exe CGI's working again on Windows.
2357 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
2358 they keep track of whether or not their post config hook has been
2359 called before. Instead of a static variable (which is replaced when
2360 the DSO is loaded a second time), use userdata in the process pool.
2363 Changes with Apache 2.0a9
2365 *) Win32 now requires perl to complete the final install step for users
2366 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
2367 and installs the conf, htdocs and htdocs/manual directories.
2370 *) Make mod_include use a hash table to associate directive tags with
2371 functions. This allows modules to implement their own SSI tags easily.
2372 The idea is simple enough, a module can insert it's own tag and function
2373 combination into a hash table provided by mod_include. While mod_include
2374 parses an SSI file, when it encounters a tag in the file, it does a
2375 hash lookup to find the function that implements that tag, and passes
2376 all of the relevant data to the function. That function is then
2377 responsible for processing the tag and handing the remaining data back
2378 to mod_include for further processing.
2379 [Paul J. Reder <rederpj@raleigh.ibm.com>]
2381 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
2382 fewer parameters: the local and remote socket addresses were removed
2383 from the parameter list because all required information is available
2384 via the APR socket. [Jeff Trawick]
2386 *) Distribution directory structure reorganized to reflect a
2387 normal source distribution with external install targets.
2390 *) The MPMs that need multiple segments of shared memory now create
2391 two apr_shmem_t variables, one for each shared memory allocation.
2392 the problem is that we can't determine how much memory will be required
2393 for shared memory allocations once we try to allocate more than one
2394 variable. The MM code automatically aligns the shared memory allocations,
2395 so we end up needing to pad the amount of shared memory we want based
2396 on how many variables will be allocated out of the shared memory segment.
2397 It is just easier to create a second apr_shmem_t variable, and two
2398 shmem memory blocks.
2401 *) Cleanup the export list a bit. This creates a single unified list of
2402 functions exported by APR. The export list is generated at configure
2403 time, and that list is then used to generate the exports.c file.
2404 Because of the way the export list is generated, we only export those
2405 functions that are valid on the platform we are building on.
2408 *) Enable logging the cookie with mod_log_config
2409 [Sander van Zoest <sander@covalent.net>]
2411 *) Fix a segfault in mod_info when it reaches the end of the configuration.
2414 *) Added lib/aputil/ as a placeholder for utility functions which are not
2415 specific to the Apache HTTP Server (but do not make sense with APR).
2416 The first utility is "apu_dbm": a set of functions to work with DBM
2417 files. This first version can be compiled for SDBM or GDBM databases.
2420 *) Complete re-write of mod_include. This makes mod_include a filter that
2421 uses buckets directly. This has now served the FAQ correctly.
2422 [Paul Reder <rederpj@raleigh.ibm.com>]
2424 *) Allow modules to specify the first filter in a sub_request when
2425 making the sub_request. This keeps modules from having to change the
2426 output_filter immediately after creating the sub-request, and therefore
2427 skip the sub_req_output_filter. [Ryan Bloom]
2429 *) Update ab to accept URLs with IPv6 literal address strings (in the
2430 format described in RFC 2732), and to build Host header fields in
2431 the same format. This allows IPv6 literal address strings to be
2432 used with ab. This support has been tested against Apache 1.3 with
2433 the KAME patch, but Apache 2.0 does not yet work with this format
2434 of the Host header field. [Jeff Trawick]
2436 *) Accomodate an out-of-space condition in the piped logs and the
2437 rotatelogs.c code, and no longer churn log processes for this
2438 condition. [Victor J. Orlikowski]
2440 *) Add support for partial writes with apr_sendfile() to core_output_filter.
2443 Changes with Apache 2.0a8
2445 *) Add a directive to mod_mime so that filters can be associated with
2449 *) Get multi-views working again. We were setting the path_info
2450 field incorrectly if we couldn't find the specified file.
2453 *) Fix 304 processing. The core should never try to send the headers
2454 down the filter stack. Always, just setup the table in the request
2455 record, and let the header filter convert it to data that is ready
2459 *) More fixes for the proxy. There are still bugs in the proxy code,
2460 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
2464 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
2467 *) APR: Add new apr_getopt_long function to handle long options.
2468 [B. W. Fitzpatrick <fitz@red-bean.com>]
2470 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
2471 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
2472 hostname resolution/address string parsing and building
2473 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
2474 of one of the apr_sockaddr_t structures for a socket. Change
2475 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
2477 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
2478 I have proxied pages with it, cleanup will commence soon.
2481 *) Make the proxy work with filters. This isn't perfect, because we
2482 aren't dealing with the headers properly. [Ryan Bloom]
2484 *) Do not send a content-length iff the C-L is 0 and this is a head
2485 request. [Ryan Bloom]
2487 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
2488 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
2490 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
2492 *) Get the default_handler to stop trying to deal with HEAD requests.
2493 The idea is to let the content-length filter compute the C-L before
2494 we try to send the data. If we can get the C-L correctly, then we
2495 should send it in the HEAD response.
2498 *) The Header filter can now determine if a body should be sent based
2499 on r->header_only. The general idea of this is that if we delay
2500 deciding to send the body, then we might be able to compute the
2501 content-length correctly, which will help caching proxies to cache
2502 our data better. Any handler that doesn't want to try to compute
2503 the content-length can just send an EOS bucket without data and
2504 everything will just work.
2507 *) Add the referer to the error log if one is available.
2508 [Markus Gyger <mgyger@itr.ch>]
2510 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
2511 change, the root of the configuration tree has been exposed to modules
2513 [Ryan Morgan <rmorgan@covalent.net>]
2515 *) Get the core_output_filter to use the bucket interface directly.
2516 This keeps us from calling the content-length filter multiple times
2517 for a simple static request.
2520 *) We are sending the content-type correctly now.
2521 [Ryan Bloom and Will Rowe]
2523 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
2524 a bogus bytes-sent value when the only thing being sent was trailers
2525 and writev() returned an error (or EAGAIN). [Jeff Trawick]
2527 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
2528 hints file to determine which platforms define
2529 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
2532 *) APR: add apr_get_home_directory() [Jeff Trawick]
2534 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
2536 *) Not all platforms have INADDR_NONE defined by default. Apache
2537 used to make this check and define INADDR_NONE if appropriate,
2538 but APR needs the check too, and I suspect other applications will
2539 as well. APR now defines APR_INADDR_NONE, which is always a valid
2540 value on all platforms.
2541 [Branko Èibej <brane@xbc.nu>]
2543 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
2544 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
2546 *) Relax the syntax checking of Host: headers in order to support
2547 iDNS. PR#6635 [Tony Finch]
2549 *) When reading from file buckets we convert to an MMAP if it makes
2550 sense. This also simplifies the default handler because the
2551 default handler no longer needs to try to create MMAPs.
2554 *) BUFF has been removed from the main server. The BUFF code will remain
2555 in the code until it has been purged from the proxy module as well.
2558 *) Byteranges have been completely re-written to be a filter. This
2559 has been tested, and I believe it is working correctly, but it could
2560 doesn't work for the Adobe Acrobat plug-in. The output almost matches
2561 the output from 1.3, the only difference being that 1.3 includes
2562 a content-length in the response, and this does not.
2565 *) APR read/write functions and bucket read functions now operate
2566 on unsigned integers, instead of signed ones. It doesn't make
2567 any sense to use signed ints, because we return the error codes,
2568 so if we have an error we should report 0 bytes read or written.
2571 *) Always compute the content length, whether it is sent or not.
2572 The reason for this, is that it allows us to correctly report
2573 the bytes_sent when logging the request. This also simplifies
2574 content-length filter a bit, and fixes the actual byte-reporing
2575 code in mod_log_config.c
2578 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
2579 it says, because it was only used by EOS and FLUSH buckets. Since
2580 neither of those are required at the end of a brigade, this was
2581 really signifying FLUSH_THE_DATA, but that can be determined better
2582 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
2583 buckets now return a length of 0, which is actually the amount of data
2584 read, so they make more sense.
2587 *) Allow the core_output_filter to save some data past the end of a
2588 request. If we get an EOS bucket, we only send the data if it
2589 makes sense to send it. This allows us to pipeline request
2590 responses. As a part of this, we also need to allocate mmap
2591 buckets out of the connection pool, not the request pool. This
2592 allows the mmap to outlive the request.
2595 *) Make blocking and non-blocking bucket reads work correctly for
2596 sockets and pipes. These are the only bucket types that should
2597 have non-blocking reads, because the other bucket types should
2598 ALWAYS be able to return something immediately.
2601 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
2602 server, but use Ctrl+Break to initiate a graceful restart
2603 instead of duplicating behavior. [John Sterling]
2605 *) Patch mod_autoindex to set the Last-Modified header based on
2606 the directory's mtime, and add the ETag header. [William Rowe]
2608 *) Merge the 1.3 patch to add support for logging query string in
2609 such a way that "%m %U%q %H" is the same as "%r".
2612 *) Port three log methods from mod_log_config 1.3 to 2.0:
2613 CLF compliant '-' byte count, method and protocol.
2616 *) Add a new LogFormat directive, %c, that will log connection
2617 status at the end of the response as follows:
2618 'X' - connection aborted before the response completed.
2619 '+' - connection may be kept-alive by the server.
2620 '-' - connection will be closed by the server.
2623 *) Expand APR for WinNT to fully accept and return utf-8 encoded
2624 Unicode file names and paths for Win32, and tag the Content-Type
2625 from mod_autoindex to reflect that charset if the the feature
2626 macro APR_HAS_UNICODE_FS is true. [William Rowe]
2628 *) Compute the content length (and add appropriate header field) for
2629 the response when no content length is available and we can't use
2630 chunked encoding. [Jeff Trawick]
2632 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
2633 so that content input filters get dechunked data when using
2634 the default handler. Also removed REQUEST_CHUNKED_PASS.
2637 *) Add mod_ext_filter as an experimental module. This module allows
2638 the administrator to use external programs as filters. Currently,
2639 only filtering of output is supported. [Jeff Trawick]
2641 *) Most Apache functions work on EBCDIC machines again, as protocol
2642 data is now translated (again). [Jeff Trawick]
2644 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
2645 the EBCDIC support. They are noops on ASCII machines, so this
2646 type of translation doesn't have to be surrounded by #ifdef
2647 CHARSET_EBCDIC. [Jeff Trawick]
2649 *) Fix mod_include. tag commands work again, and the server will
2650 send the FAQ again. This also allows mod_include to set aside
2651 buckets that include partial buckets.
2652 [Ryan Bloom and David Reid]
2654 *) Add suexec support back. [Manoj Kasichainula]
2656 *) Lingering close now uses the socket directly instead of using
2657 BUFF. This has been tested, but since all we can tell is that it
2658 doesn't fail, this needs to be really hacked on.
2661 *) Allow filters to modify headers and have those headers be sent to
2662 the client. The idea is that we have an http_header filter that
2663 actually sends the headers to the network. This removes the need
2664 for the BUFF to send headers.
2667 *) Charset translation: mod_charset_lite handles translation of
2668 request bodies. Get rid of the xlate version of ap_md5_digest()
2669 since we don't compute digests of filtered (e.g., translated)
2670 response bodies this way anymore. (Note that we don't do it at
2671 all at the present; somebody needs to write a filter to do so.)
2674 *) Input filters and ap_get_brigade() now have a input mode parameter
2675 (blocking, non-blocking, peek) instead of a length parameter.
2678 *) Update the mime.types file to the registered media types as
2679 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
2682 *) Namespace protect some macros declared in ap_config.h
2685 *) Support HTTP header line folding with input filtering.
2688 *) Mod_include works again. This should still be re-written, but at
2689 least now we can serve an SHTML page again.
2692 *) Begin to remove BUFF from the core. Currently, we keep a pointer
2693 to both the BUFF and the socket in the conn_rec. Functions that
2694 want to use the BUFF can, functions that want to use the socket,
2695 can. They point to the same place.
2698 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
2699 [Tomas "Ögren" <stric@ing.umu.se>]
2701 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
2702 associated pool goes away. (APR pipes on OS/2 were already had this
2703 logic.) This resolvs a fatal file descriptor leak with CGIs.
2706 *) The final line of the config file was not being read if there was
2707 no \n at the end of it. This was caused by apr_fgets returning
2708 APR_EOF even though we had read valid data. This is solved by
2709 making cfg_getline check the buff that was returned from apr_fgets.
2710 If apr_fgets return APR_EOF, but there was data in the buf, then we
2711 return the buf, otherwise we return NULL.
2714 *) Piped logs work again in the 2.0 series.
2717 *) Restore functionality broken by the mod_rewrite security fix:
2718 rewrite map lookup keys and default values are now expanded
2719 so that the lookup can depend on the requested URI etc.
2720 PR #6671 [Tony Finch]
2722 *) Tighten up the syntax checking of Host: headers to fix a
2723 security bug in some mass virtual hosting configurations
2724 that can allow a remote attacker to retrieve some files
2725 on the system that should be inaccessible. [Tony Finch]
2727 *) Add a pool bucket type. This bucket is used for data allocated out
2728 of a pool. If the pool is cleaned before the bucket is destroyed, then
2729 the data is converted to a heap bucket, allowing it to survive the
2733 *) Add a flush bucket. This allows modules to signal that the filters
2734 should all flush whatever data they currently have. There is no way
2735 to actually force them to do this, so if a filter ignores this bucket,
2736 that's life, but at least we can try with this.
2739 *) Add an output filter for sub-requests. This filter just strips the
2740 EOS bucket so that we don't confuse the main request's core output
2741 filter by sending multiple EOS buckets. This change also makes sub
2742 requests start to send EOS buckets when they are finished.
2745 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
2746 makes ap_bucket_destroy a return void, which is okay because it
2747 used to always return APR_SUCCESS, and nobody ever checked its
2748 return value anyway.
2749 [Cliff Woolley <cliffwoolley@yahoo.com>]
2751 *) Remove the index into the bucket-type table from the buckets
2752 structure. This has now been replaced with a pointer to the
2753 bucket_type. Also add some macros to test the bucket-type.
2756 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
2757 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
2758 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
2759 All _VAR_ flavors changes to _DATA to be absolutely clear.
2762 *) Add support for /, //, //servername and //server/sharename
2763 parsing of <Directory> blocks under Win32 and OS2.
2764 [Tim Costello, William Rowe, Brian Harvard]
2766 *) Remove the function pointers from the ap_bucket type. They have been
2767 replaced with a global table. Modules are allowed to register bucket
2768 types and use then use those buckets.
2771 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
2772 once we finish writing the request body to the cgi child process;
2773 otherwise, the client doesn't hit EOF on stdin. Small request bodies
2774 worked without this change (for reasons I don't understand), but large
2775 ones didn't. [Jeff Trawick]
2777 *) Remove file bucket specific information from the ap_bucket type.
2778 This has been moved to a file_bucket specific type that hangs off
2779 the data pointer in the ap_bucket type.
2782 *) Input filtering now has a third argument. This is the amount of data
2783 to read from lower filters. This argument can be -1, 0, or a positive
2784 number. -1 means give me all the data you have, I'll deal with it and
2785 let you know if I need more. 0 means give me one line and one line
2786 only. A positive number means I want no more than this much data.
2788 Currently, only 0 and a positive number are implemented. This allows
2789 us to remove the remaining field from the conn_rec structure, which
2793 *) Big cleanup of the input filtering. The goal is that http_filter
2794 understands two conditions, headers and body. It knows where it is
2795 based on c->remaining. If c->remaining is 0, then we are in headers,
2796 and http_filter returns a line at a time. If it is not 0, then we are
2797 in body, and http_filter returns raw data, but only up to c->remaining
2798 bytes. It can return less, but never more.
2799 [Greg Ames, Ryan Bloom, Jeff Trawick]
2801 *) mod_cgi: Write all of the request body to the child, not just what
2802 the kernel would accept on the first write. [Jeff Trawick]
2804 *) Back out the change that moved the brigade from the core_output_filters
2805 ctx to the conn_rec. Since all requests over a given connection
2806 go through the same core_output_filter, the ctx pointer has the
2810 *) Fix another bug in the send_the_file() read/write loop. A partial
2811 send by apr_send would cause unsent data in the read buffer to
2812 get clobbered. Complete making send_the_file handle partial
2813 writes to the network.
2816 *) Fix a couple of type fixes to allow compilation on AIX again
2817 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
2819 *) Fix bug in send_the_file() which causes offset to be ignored
2820 if there are no headers to send.
2823 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
2824 filter. Useful for supporting Windows 9* with a binary
2825 compiled on Windows NT.
2828 Changes with Apache 2.0a7
2830 *) Reimplement core_output_filter to buffer/save bucket brigades
2831 across multiple calls to the core_filter. The brigade will be
2832 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
2833 thresholds are hit or the EOS bucket is received.
2836 *) Create experimental filter (buffer_filter) that coalesces bytes
2837 into one large buffer before invoking the next filter in the
2838 chain. This filter is particularly useful with the current
2839 implementation of mod_autoindex when it inserted above the
2840 chunk_filter. mod_autoindex generates a lot of brigades that
2841 containing buckets holding just a few bytes each. The
2842 buffer_filter coalesces these buckets into a single large bucket.
2845 *) Add apr_sendfile() support into the core_output_filter.
2848 *) Add apr_sendv() support into the core_output_filter.
2851 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
2852 [Mike Abbott <mja@sgi.com>]
2854 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
2855 make much sense, because Apache uses buckets instead of BUFFs now.
2858 *) send_the_file now falls back to a read/write loop on platforms that
2859 do not have sendfile.
2860 [Ryan Bloom and Brian Havard]
2862 *) Install apachectl correctly, and substitute the proper values so
2863 that it works again. [Ryan Bloom]
2865 *) Better(??) handle platforms that lack sendfile().
2868 *) APR now has UUID generation/formatting/parsing support.
2871 *) Begin the http_filter. This is an input filter that understands
2872 the absolute basic amount required to parse an HTTP Request. The
2873 goal is to be able to split headers from request body before passing
2874 the data back to the other filters.
2877 *) Bring forward from 1.3.13 the config directory implementation
2880 *) install apxs if it is created
2883 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
2884 conversions. [William Rowe]
2886 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
2887 ap_add_output_filter(). [Jeff Trawick]
2889 *) Multiple build and configuration fixes
2892 -add datadir and localstatedir substitutions
2894 -fix logfilename misspelling
2895 -fix evaluation of installation dir variables and
2896 -replace $foobar by $(foobar) to be usefull in the makefile
2900 -add rules for cross-compiling in rules.mk. Okay, rule to check for
2901 $CC_FOR_BUILD is still missing
2902 -use CHECK_TOOL instead of CHECK_PROG for ranlib
2903 -add missing "AR=@AR@" to severaly Makefile.in's
2904 -cache result for "struct rlimit"
2905 -compile all helper programs with native and cross compiler
2906 and use the native version to generate header file
2907 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
2909 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
2911 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
2913 *) Fix a bug where a client which only sends \n to delimit header
2914 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
2915 message. Start working on ebcdic co-existance with input
2917 [William Rowe, Greg Ames]
2919 *) If mod_so is enabled in the server always create libexec, even
2920 if there are no modules installed in this directory. This is a
2921 requirement for APXS to work correctly.
2924 *) Connection oriented output filters are now stored in the
2925 conn_rec instead of the request_rec. This allows us to add the
2926 output filter in the pre-connection phase instead of the
2927 post_read_request phase, which keeps us from trying to write an
2928 error page before we have a filter to write to the network.
2929 [Ryan Bloom, Jeff Trawick, and Greg Ames]
2931 *) Cleaning up an mmap bucket no longer deletes the mmap. An
2932 mmap can be used across multiple buckets (default_handler with
2933 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
2934 the mmap itself can't be associated with the bucket.
2937 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
2940 *) Radical surgery to improve mod_isapi support under Win32.
2941 Includes a number of newer ServerSupportFunction calls, support
2942 for ReadClient (in order to retrieve POSTs greater than 48KB),
2943 and general bug fixes to more reliably load ISAPI .dll's and
2944 prevent leaking handle resources. Note: There are still
2945 discrepancies between IIS's and Apache's ServerVariables, and
2946 async calls are still not supported. Additional warnings are
2947 logged to facilitate debugging of unsupported ISAPI calls.
2950 *) Add input filtering to Apache. The basic idea for the input
2951 filters is the same as the ideas for output filters. The biggest
2952 difference is that instead of calling ap_pass_brigade, ap_get_brigade
2953 should be called, and the order of execution for the filter itself is
2954 different. When writing an output filter, a brigade is passed in,
2955 and filters operate directly on that brigade, when done, they call
2956 ap_pass_brigade. Input filters are the exact opposite. Because input
2957 is not a push operation, filters first call ap_get_brigade. When this
2958 function returns, the input filter will be left with a valid brigade.
2959 The input filter should then operate on the brigade, and return.
2962 *) Fix building on BSD/OS using its native make. The build system
2963 falls back to the BSD .include directive on that host platform.
2966 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
2967 SHA1 and plaintext password encodings. Make feature tests a
2968 bit more flexible. [William Rowe]
2970 *) Charset translation: mod_charset_lite handles output content
2971 translation in a filter. mod_charset_lite no longer ignores
2972 subrequests. A bunch of cruft related to BUFF's support for
2973 translating request and response bodies was removed.
2976 *) Move the addition of the CORE filter to the post_read_request
2977 hook in http_core.c. This removes the need to add the filter in
2978 multiple places and allows for an SSL module to be added much
2979 simpler. [Ryan Bloom]
2981 *) Fix a security problem that affects certain configurations of
2982 mod_rewrite. If the result of a RewriteRule is a filename that
2983 contains expansion specifiers, especially regexp backreferences
2984 $0..$9 and %0..%9, then it may be possible for an attacker to
2985 access any file on the web server. [Tony Finch]
2987 *) Fix a bug where errors that are detected during early request parsing
2988 don't produce visible HTTP error messages at the browser, because
2989 the core_filter wasn't present. [Greg Ames]
2991 *) Provide apr_socklen_t as a portability aid.
2992 [Victor J. Orlikowski]
2994 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
2995 as well as a comment arg to the add, adduser and update cmds.
2996 update allows the user to clear or preserve pw/groups/comment.
2997 Fixed a bug in dbmmanage that prevented the check option from
2998 parsing a password followed by :group... text. Corrected the
2999 seed calcualation for Win32 systems, and added -lsdbm support.
3002 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
3005 *) Avoid a segfault when parsing .htaccess files. An
3006 uninitialized tree pointer was passed to ap_build_config().
3009 *) Change the way that inet_addr & inet_network are checked for
3010 in APR's configure process to allow BeOS BONE to correctly
3011 find them. With this change BeOS BONE now builds from source
3012 with no problems. [David Reid]
3014 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
3015 the end of the parameters to execve() was stored in the wrong
3016 location, overlaying the storage beyond the newargs[] array and
3017 also passing uninitialized storage to execve(), which would
3018 sometimes fail with EFAULT. [Jeff Trawick]
3020 *) Fix a bug parsing configuration file containers. With a sequence
3021 like this in the config file
3023 <IfModule mod_kilroy.c>
3026 <IfModule mod_lovejoy.c>
3031 the second container would be terminated at the blank line due to
3032 sediment in the buffer from reading the prior </IfModule> and an
3033 error message would be generated for the real </IfModule> for the
3034 second container. Also due to this problem, any two characters
3035 could be used for "</" in the close of a container.
3038 *) ap_add_filter prototype changed to remove the ctx pointer. The
3039 pointer still remains in the filter structure, but it can not be
3040 a part of the ap_add_filter prototype. The reason is that when
3041 the core uses AddFilter to add a filter to the stack it doesn't
3042 know how to allocate the ctx pointer, or even how much memory should
3043 be allocated. The filters will have to be responsible for allocating
3044 the ctx memory when they need it.
3047 *) Add an AddFilter directive. This directive takes a list of filters
3048 that should be activated for the requested resource.
3051 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
3052 some other platforms). [Jeff Trawick]
3054 *) Modify mod_include to be a filter. Currently, it has only been tested
3055 on actual files, but it should work for CGI scripts too.
3058 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
3059 writes. apr_flush() for Unix: handle interrupted writes.
3062 *) NameVirtualHost can now take "*" as an argument instead of
3063 an IP address. This allows you to create a purely name-based
3064 virtual hosting server that does not have any IP addresses in
3065 the configuration file and which ignores the local address
3066 of any connections. PR #5595, PR #4455 [Tony Finch]
3068 *) Fix some compile warnings in mod_mmap_static.c
3069 [Mike Abbott <mja@sgi.com>]
3071 *) Fix chunking problem with CGI scripts. The general problem was that
3072 the CGI modules were adding an EOS bucket and then the core added an
3073 EOS bucket. The chunking filter finalizes the chunked response when it
3074 encounters an EOS bucket. Because two EOS buckets were sent, we
3075 finalized the response twice. The fix is to make sure we only send one
3076 EOS, by utilizing a flag in the request_rec.
3079 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
3080 and Win32. Previously, the first read from an apr_file_t set up via
3081 apr_put_os_file() would return a '\0'. [Jeff Trawick]
3083 *) Mod_cgid now creates a single element bucket brigade, with a pipe
3084 bucket, instead of using BUFF's and ap_r*.
3087 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
3088 [Mike Abbott <mja@sgi.com>]
3090 *) Remove ap_bopenf from buff code. This required modifying the file_cache
3091 code to use APR file's directly instead of going through BUFFs.
3094 *) Fix compile break on some platforms for mod_mime_magic.c
3095 [John K. Sterling <sterling@covalent.net>]
3097 *) Fix merging of AddDefaultCharset directive.
3098 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
3100 *) Minor revamp of the rlimit sections of code. We now test
3101 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
3102 is now "available" even if the platform doesn't support
3103 the rlimit family (it's just a noop though). [Jim Jagielski]
3105 *) Migrate the pre-selection of which MPM to use for specific
3106 platforms to hints.m4, which contains (or should contain)
3107 all platform specific "hints". [Jim Jagielski]
3109 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
3112 *) Add tables with non-string/binary values to APR.
3115 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
3118 *) Update PCRE to version 3.2. [Ryan Bloom]
3120 *) Change the way buckets' destroy functions are called so that
3121 they can be more directly used when changing the type of a
3122 bucket in place. [Tony Finch]
3124 *) Add generic support for reference-counting the resources used by
3125 buckets, and alter the HEAP and MMAP buckets to use it. Change
3126 the way buckets are initialised to support changing the type of
3127 buckets in place, and use it when setting aside TRANSIENT buckets.
3128 Change the implementation of TRANSIENT buckets so that it can be
3129 mostly shared with IMMORTAL buckets, which are now implemented.
3132 Changes with Apache 2.0a6
3134 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
3136 *) Add a chunking filter to Apache. This brings us one step closer
3137 to removing BUFF. [Ryan Bloom]
3139 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
3140 added to the stack is the last filter to be called. [Ryan Bloom]
3142 *) Apache 2.0 has been completely documented using Scandoc. The
3143 docs can be generated by running 'make docs'. [Ryan Bloom]
3145 *) Add filtered I/O to Apache. This is based on bucket brigades,
3146 Currently the buckets still use BUFF under the covers, but that
3147 should change quickly. The only currently written filter is the
3148 core filter which just calls ap_bwrite. [The Apache Group]
3150 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
3151 built with thread support. [Jeff Trawick]
3153 *) Abort configuration if --with-layout was specified and there's
3154 no layout definition file. [Ken Coar]
3156 *) Add support for '--with-port=n' option to configure. [Ken Coar]
3158 *) Add support for extension methods for the Allow response header
3159 field, and an API routine for accessing r->allowed and the
3160 list of extension methods in a unified manner. [Ken Coar]
3162 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
3163 [Rob Simonson <simo@us.ibm.com>]
3165 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
3166 APACHE_XLATE builds. [Jeff Trawick]
3168 *) A configuration file parsing problem was fixed. When the
3169 configuration file started with an IfModule/IfDefine container,
3170 only the last statement in the container would be retained.
3173 Changes with Apache 2.0a5
3175 *) Perchild is serving pages after passing them to different child
3176 processes. There are still a lot of bugs, but this does work. I
3177 have made requests against the same installation of Apache, and had
3178 different servers use different user IDs to serve the responses.
3179 This change moves to using socketpair instead of an AF_UNIX socket.
3182 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
3183 It can't seem to pass between child processes yet, but I think we
3184 are closer now than before. This moves us back to using Unix
3185 Domain Sockets. [Ryan Bloom]
3187 *) libapr functions and types renamed with apr_ prefix.
3188 #include "apr_compat.h" for 1.3.x backwards compat
3191 *) Fix problems with APR sockaddr handling on Win32. It didn't always
3192 return the right information on the local socket address.
3193 [Gregory Nicholls <gnicholls@level8.com>]
3195 *) ap_recv() on Win32: Set bytes-read to 0 on error.
3196 [Gregory Nicholls <gnicholls@level8.com>]
3198 *) Add an option to not detach from the controlling terminal without
3199 going into single process mode. This allows for much easier
3200 debugging of the process startup code. [Ryan Bloom]
3202 *) ab: don't use perror() to report the failure of an APR function.
3205 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
3206 scoreboard on graceful restarts.
3209 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
3210 An invalid ap_proc_t was passed to ap_create_process().
3213 *) Allow modules to register filters. Those filters are still
3214 never called, but this is a step in the right direction.
3215 [Ryan Bloom and Greg Stein]
3217 *) Register the mod_cgid daemon process for cleanup so that it is
3218 killed at termination if it does not die when the parent gets
3219 SIGTERM. This change is to fix occasional problems where the
3220 process stays around. Bugs in similar logic in mod_rewrite and
3221 mod_include were also fixed. [Jeff Trawick]
3223 *) Fix a bug in the time handling. Basically, we were imploding a time
3224 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
3225 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
3226 uses those two fields to adjust the time value. Because of the HTTP
3227 spec, both of those values can be zero'ed out safely. This fixes
3228 the bug correctly. [Ryan Bloom]
3230 *) Fix a couple of place in the Windows code where the wrong error
3231 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
3233 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
3235 *) Added the APR_EOL_STR macro for platform dependent differences in
3236 logfiles and other raw text (such as all APR files). Fixes logfiles
3237 not terminated with cr/lf sequences in Win32. [William Rowe]
3239 *) Move all strings functions in APR to src/lib/apr/strings and create
3240 apr_strings.h for the prototypes. [Ryan Bloom]
3242 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
3243 to repeat the syscall until we stop getting EINTR. I noticed a
3244 related problem at termination (SIGTERM) on FreeBSD when using
3245 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
3246 implementation work properly with child init. Previously, ap_lock()
3247 was essentially a no-op because all children were using different
3248 locks and thus nobody ever blocked. [Jeff Trawick]
3250 *) The htdocs/ tree has been moved out of the CVS source tree into
3251 a separate area for easier development. This has NO EFFECT on
3252 end-users or Apache installations. [Ken Coar]
3254 *) Integrate the mod_dav module for WebDAV protocol handling. This
3255 adds the dav and dav_fs modules, the SDBM library, and additional
3256 XML handling utilities. [Greg Stein]
3258 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
3261 *) Update the lib/expat-lite/ library (bring forward changes from
3262 the Apache 1.3 repository). [Greg Stein]
3264 *) If sizeof(long long) == sizeof(long), then prefer long in APR
3265 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
3267 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
3268 machines where sendfile is detected, but nobody has written ap_sendfile.
3269 [Dave Hill <ddhill@zk3.dec.com>]
3271 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
3273 *) ab would start up more connections than needed, then quit when the
3274 desired number were finished. Also fixed a logic error involving
3275 ab keepalives. [Victor J. Orlikowski]
3277 *) WinNT: Implement non-blocking pipes with timeouts to communicate
3278 with CGIs. Apache 2.0a4 had non-blocking pipes but without
3279 timeouts (i.e, if a timeout was specified, the pipe reverted to
3280 a full blocking pipe). Now the behaviour is more in line with
3281 Unix non-blocking pipes.
3284 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
3285 cache open file handles along with accept socket reuse enables
3286 Apache 2.0 to serve non-keepalive requests for static files at
3287 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
3288 and Apache 2.0 will serve almost 1200 rps on my system).
3291 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
3292 supports two config directives, mmapfile (same behavious as
3293 mod_mmap_static) and cachefile. Use the cachefile directive
3294 to cache open file handles. This directive only works on systems
3295 that have implemented the ap_sendfile API. cachefile works today
3296 on Windows NT, but has not been tested on any flavors of Unix.
3299 *) Cleanup the configuration. With the last few changes the
3300 configuration process automatically:
3301 inherits information about how to build from APR. Allowing
3302 APR to inform Apache that it should or should not use -ldl
3304 Detects which mod_cgi should be used mod_cgi or mod_cgid,
3305 based on the threading model
3307 Apache calls APR's configure process before finishing it's
3308 configuration processing, allowing for more information flow
3313 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
3314 with non-zero argument makes the socket non-blocking. BeOS and
3315 OS/2 already worked this way. [Jeff Trawick]
3317 *) ap_close() now calls ap_flush() for buffered files, so write
3318 operations work a whole lot better on buffered files.
3321 *) Fix error messages issued from MPMs which explain where to change
3322 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
3325 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
3326 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
3327 now the way that the blocking state of a pipe is manipulated.
3328 ap_block_pipe() is gone. [Jeff Trawick]
3330 *) Correct the problem where the only local host name that the IP stack
3331 can discover are 'undotted' private names. If no fully qualified
3332 domain name can be identified, the default ServerName will be set to
3333 the machine's IP address string. A warning is always provided if the
3334 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
3336 *) Repair problems with config file processing which caused segfault
3337 at init when virtual hosts were defined and which caused ServerName to
3338 be ignored when there was no valid DNS setup. [Jeff Trawick]
3340 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
3342 *) Add ap_sendfile implementation for AIX
3343 [Victor J. Orlikowski]
3345 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
3346 apr_network_io.h, and apr_thread_proc.h.
3347 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
3349 *) Bring the allocation and pool debugging code back into a working
3350 state. This will need to be tested as so far it's only been used on
3353 *) Change configuration command setup to be properly typesafe when in
3354 maintainer mode. Note that this requires a compiler that can initialise
3355 unions. [Ben Laurie]
3357 *) Turn on buffering for config file reads. Part of this was to
3358 repair buffered I/O support in Unix and implement buffered
3359 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
3361 *) Win32: Fix problem where UTC offset was not being set correctly
3362 in the access log. Problem reported on news group by Jerry Baker.
3365 *) Fix segfault when reporting this type of syntax error:
3366 "</container> without matching <container> section", where
3367 container is VirtualHost or Directory or whatever.
3370 *) Prevent the source code for CGIs from being revealed when using
3371 mod_vhost_alias and the CGI directory is under the document root
3372 and a user makes a request like http://www.example.com//cgi-bin/cgi
3373 as reported in <news:960999105.344321@ernani.logica.co.uk>
3376 *) Add support for the new Beos NetwOrking Environment (BONE)
3379 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
3380 final input char is incomplete; ap_bwrite_xlate() now handles
3381 incomplete final input chars. [Jeff Trawick]
3383 *) Yet another update to saferead/halfduplex stuff -- need to ensure
3384 that a bhalfduplex call occurs before logging or else DNS and
3385 such can delay the last packet of the response. [Dean Gaudet]
3387 *) Some syscall reduction in APR on unix -- don't seek when setting
3388 up an mmap; and don't fcntl() more than once per socket.
3391 *) When mod_cgid is started as root, the cgi daemon now switches
3392 to the configured User/Group (like other httpd processes)
3393 instead of continuing as root. [Jeff Trawick]
3395 *) The prefork MPM now uses an APR lock for the accept() mutex.
3396 It has not been getting a lock at all recently. httpd -V now
3397 displays APR's selection of the lock mechanism instead of the
3398 symbols previously respected by prefork. [Jeff Trawick]
3400 *) Change the mmap() feature test to check only for existence.
3401 The previous check required features not used by Apache.
3404 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
3405 sometimes mangled. The len parm to accept() was not
3406 initialized, leading sometimes to an endless loop of failed
3407 accept() calls on OS/390 and anywhere else that failed the call
3408 if the len was negative. Use <sys/un.h> for struct sockaddr_un
3409 instead of declaring it ourselves to fix a compilation problem
3410 on Solaris. [Jeff Trawick]
3412 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
3414 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
3416 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
3418 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
3419 initialization if ALLOC_DEBUG is defined; no known symptom
3420 otherwise. [Jeff Trawick]
3422 *) Fix typo in configure script when checking for mod_so. bash
3423 doesn't seem to have a problem but /bin/sh on Solaris does.
3424 Symptom: "./configure: test: unknown operator =="
3427 *) Rebind the Win32 NT and 9x services control into the MPM.
3428 All console, WinNT SCM and Win9x pseudo-service control code is
3429 now wrapped within the WinNT MPM.
3432 *) Make a copy of getenv("PATH") before storing for later use. Some
3433 getenv() implementations use the same storage for successive calls.
3434 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
3436 *) Server Tokens work in 2.0 again. This also propogates the change
3437 to allow just the product name in the server string using
3441 Changes with Apache 2.0a4
3443 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
3444 won't need to call it. [Greg Ames, Jeff Trawick]
3446 *) Move pre_config hook call to between configuration read and config
3447 tree walk. This allows all modules to implement pre_config hooks
3448 and know that they will be called at an appropriate time.
3451 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
3454 *) Add pre-config hooks back to all modules.
3457 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
3458 ContentDigest enabled and we can't/don't mmap the file.
3461 *) We now report the correct line number for syntax errors in config
3462 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
3464 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
3465 related bugs, and changed shmem/locking to use apr API. Shared-mem
3466 is currently disabled, however, because of problems with graceful
3467 restarts. [Ronald Tschalär]
3469 *) Fix corruption of IFS variable in --with-module= handling.
3470 Depending on the user's shell or customization thereof, there
3471 would be errors generating ap_config_auto.h later in the configure
3472 procedure. [Jeff Trawick]
3474 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
3475 isn't used (as in 1.3), except that on Unix it is now logged via
3476 ap_log_rerror() instead of by the child having STDERR_FILENO refer
3477 to the error log. [Greg Ames, Jeff Trawick]
3479 *) Add '-D' argument processing for run time configuration defines.
3482 *) Organize http_main.c as independent code, such that no code or
3483 global data is exported from it. WIN32 will dynamically link it
3484 to the server core, so this will prevent mutual dependency.
3487 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
3488 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
3491 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
3492 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
3494 *) Add mod_charset_lite for configuring character set translation.
3497 *) Add '-n' option to htpasswd to make it print its user:pw record
3498 on stdout rather than having to frob a text file. [Ken Coar]
3500 *) Fix saferead. Basically, we flush the output buffer if a read on the
3504 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
3505 a conversion is single-byte only. [Jeff Trawick]
3507 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
3508 the BeOS 5.0 documentation says that shutdown doesn't work yet.
3511 *) Fix some minor errors where pid was being manipulated as an int
3512 instead of the portable pid_t. [Roy Fielding]
3514 *) Fix some error log prints that were printing the pointer to a
3515 structure rather than the pid within the structure.
3516 [Jeff Trawick, Roy Fielding]
3518 *) ab: Fix a command-line processing bug; track bad headers in
3519 err_response; support reading headers up to 2K.
3520 [Ask Bjoern Hansen <ask@valueclick.com>]
3522 *) Fix ap_resolve_env() so that it handles new function added in a prior
3523 alpha (see "Added the capability to do ${ENVVAR} constructs in the
3524 config file.") as well as the constructs used by mod_rewrite.
3525 [Paul Reder <rederpj@raleigh.ibm.com>]
3527 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
3529 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
3530 APR to perform translation, instead of accessing the hard-coded tables
3531 in 1.3's ebcdic.c. [Jeff Trawick]
3533 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
3536 *) Add the ability to hook into the config file reading phase. Basically
3537 if a directive is specified EXEC_ON_READ, then when that directive is
3538 read from the config file, the assocaited function is executed. This
3539 should only be used for those directives that must muck with HOW the
3540 server INTERPRETS the config. This should not be used for directives
3541 that re-order or replace items in the config tree. Those changes should
3542 be made in the pre-config step.
3545 *) Add mod_example to the build system.
3548 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
3549 byte character sets. [Jeff Trawick]
3551 *) Pick up various EBCDIC fixes from 1.3 (from Martin
3552 Kraemer and Oliver Reh originally according to the change log).
3555 *) Fix a couple of problems in RFC1413 support (controlled by the
3556 IdentityCheck directive). Apache did not build the request string
3557 properly and more importantly Apache would loop forever if the
3558 would-be ident server dropped the connection before sending a
3559 properly terminated response. [Jeff Trawick]
3561 *) apxs works in 2.0.
3564 *) Reliable piped logs work in 2.0.
3567 *) Introduce a hash table implementation into APR to be used for
3568 replacing tables and other random data structures in Apache.
3571 *) Add some more error reporting to htpasswd in the case of problems
3572 generating or accessing the temporary file. Also, pass in a
3573 buffer if the implementation knows how to use it (i.e., if L_tmpnam
3574 is defined). [Ken Coar]
3576 *) Configure creates config.nice now containing your configure
3577 options. Syntax: ./config.nice [--more-options]
3580 *) Fix various return code problems in APR on Win32. For most of
3581 these, APR was returning APR_EEXIST instead of GetLastError()/
3582 WSAGetLastError(). [Jeff Trawick]
3584 *) Make piped logs work again in version 2.0
3587 *) Add VPATH support to UNIX build system of Apache and APR.
3590 *) Fix ap_tokenize_to_argv to respect the const arguments that are
3594 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
3595 Patch submitted to author.
3598 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
3599 /sbin in PATH on FreeBSD (all submitted to rse previously)
3602 *) Fix building Pthread-based MPMs on OpenBSD
3603 [Sascha Schumann] PR#26
3605 *) Fix ap_readdir() problem on systems where d_name[] field in
3606 struct dirent is declared with only one byte. (This problem only
3607 affected multithreaded builds.) This caused a segfault during
3608 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
3609 least). [Jeff Trawick]
3611 *) Fix some make-portability problems on at least Tru64, Irix
3613 [Sascha Schumann] PR#18, PR#39
3615 *) Add ap_sigwait() to support old-style sigwait() on systems
3616 like OS/390 and UnixWare.
3619 *) Add POSIX-thread flags for more platforms.
3622 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
3623 (on Unix, at least) to handle resolver errors. Fix a bug in
3624 the definition of APR_ENOMEM so that ap_strerror() can spit
3625 out the correct error message for it.
3628 Changes with Apache 2.0a3
3630 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
3633 *) API: *HOOK* macros now have an AP_ prefix
3636 *) Win32: Eliminate redundant calls to initialize winsock.
3637 [Tim Costello <timcostello@ozemail.com.au>]
3639 *) Fix bugs initializing ungetchar for pipes.
3640 [Chia-liang Kao <clkao@CirX.ORG>]
3642 *) The ab program in the src/support directory is now portable using
3646 *) Support directory is being compiled when the server is built
3649 *) The configure option --with-program-name has been added to allow
3650 developers to rename the executable at configure time. This also
3651 changes the name of the config files to match the executable's name.
3654 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
3655 containing version numbers. [Martin Pool]
3657 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
3658 Unix; access_log and error_log now created with these perms; non-
3659 Unix is unaffected [Jeff Trawick]
3661 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
3662 Replaced more magic numbers with MD5_DIGESTSIZE.
3663 [William Rowe, Roy Fielding]
3665 *) Win32: Get mod_auth_digest compiling and added to the Windows
3666 build environment. Not tested and I'd be suprised if it
3667 actually works. [Bill Stoddard]
3669 *) Revamp the Win32 make environment. Makefiles have been removed and
3670 Apache.dsw created to bring together all the pieces. Create new file
3671 os/win32/BaseAddr.ref to define module base addresses (to prevent
3672 dll relocation at start-up).
3673 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
3675 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
3676 of the \015, \012, and \015\012 constants with macros.
3677 [Greg Ames <gregames@us.ibm.com>]
3679 *) Add ap_xlate_open() et al for translation of text between different
3680 character sets. The initial implementation requires iconv().
3683 *) More FAQs and answers from comp.infosystems.www.servers.unix.
3684 [Joshua Slive <slive@finance.commerce.ubc.ca>]
3686 *) CGI output is being timed out now.
3689 *) Fix the problem with dieing quietly. dupfile now takes a pool which
3690 is used by the new apr file. There is no reason to create a new file
3691 with the same lifetime as the original file.
3694 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
3695 module base addresses. This will help shooting seg faults
3696 in the field. [William Rowe <wrowe@lnd.com>]
3698 *) Update Apache on Windows documentation. Add new document
3699 describing how to compile Apache on Windows.
3700 [William Rowe <wrowe@lnd.com>]
3702 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
3703 microseconds instead of seconds. Some storage leaks and other
3704 minor bugs in related code were fixed. [Jeff Trawick]
3706 *) Win32: First cut at getting mod_isapi working under 2.0
3707 [William Rowe <wrowe@lnd.com>]
3709 *) First stab at getting mod_auth_digest working under 2.0
3710 quick change summary:
3711 - moved the random byte generation (ap_generate_random_bytes) into APR
3712 - now uses ap_time_t
3713 - compiles and runs on linux
3715 [Brian Martin <bmartin@penguincomputing.com>]
3717 *) Win32: Move the space stripping of physical service names
3718 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
3719 unresolved symbol. Add dependency checking to the
3720 CreateService call to ensure TCPIP and AFP (winsock) is started
3722 [William Rowe <wrowe@lnd.com>]
3724 *) Win32: Add code to perform latebinding on functions that may
3725 not exist on all levels of Windows where Apache runs. This
3726 is needed to allow Apache to start-up on Win95/98. All calls
3727 to non portable functions should be protected with
3728 ap_oslevel checks to prevent runtime segfaults.
3729 [William Rowe <wrowe@lnd.com>]
3731 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
3733 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
3735 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
3736 This addresses PR 1623. Still need to address timing out runaway
3737 CGI scripts. [Bill Stoddard]
3739 *) Win32: Make ap_stat Windows 95/98 friendly
3740 [William Rowe <wrowe@lnd.com>]
3742 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
3743 always fail. Need to initialise the dwOSVersionInfoSize member of the
3744 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
3747 The patch also enhances ap_get_oslevel (and the associated enum) to
3748 handle selected service packs for NT4, and adds recognition for
3749 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
3750 we can use ReadFileScatter and WriteFileGather in readwrite.c.
3751 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
3753 *) Get mod_rewrite building and running, and mod_status building for Win NT
3754 [Allan Edwards <ake@raleigh.ibm.com>]
3756 *) Patch to port mod_auth_db to the 2.0 api and also to support
3757 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
3758 2.7.7. It should work with version 1 as well but I haven't tested it.
3759 [Brian Martin <bmartin@penguincomputing.com>]
3761 *) Get APR DSO code working under Windows. Includes cross platform
3763 [Tim.Costello@BTFinancialgroup.com]
3765 *) Fix some of the Windows APR time functions.
3768 *) FAQ changes related to tidying up historical documents on the web site.
3769 [Joshua Slive <slive@finance.commerce.ubc.ca>]
3771 *) Move Windows DSO code into APR.
3774 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
3775 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
3776 at build time. At this point, the server will not compile on Windows because
3777 of the recent DSO commits. Fixing those next.
3778 [Bill Rowe & Bill Stoddard]
3780 *) Added error checking for file I/O APR routines.
3781 [Jon Travis <jtravis@covalent.net>]
3783 *) APR: Don't use the values of resolver error codes for the
3784 corresponding APR error codes. On Unix and Win32, return the
3785 proper APR error code after a resolver error. [Jeff Trawick]
3787 Changes with Apache 2.0a2
3789 *) Renamed the executable back to httpd on all platforms other
3793 *) Allow BeOS to survive restarts, log properly and a few
3794 small things it had problems with due to the way it setup
3795 users and groups. [David Reid]
3797 *) Get mod_rewrite working with APR locks
3798 [Paul Reder <rederpj@raleigh.ibm.com>]
3800 *) Actually remove the sempahore when the lock cleanup routine
3801 is called on BeOS. [David Reid]
3803 *) Clear hook registrations between reads of the config file.
3804 When DSOs are unloaded and re-loaded the old hook pointers may
3805 no longer be valid. This fix eliminates potential segfaults.
3806 [Allan Edwards <ake@raleigh.ibm.com>]
3808 *) Fix a problem with Sigfunc not being defined or bypassed
3809 if sigaction() wasn't found. [Jim Jagielski]
3811 *) Fix the locking mechanism on BSD variants. They now use fcntl
3812 locks. This allows the server to start and serve pages.
3815 *) First cut at getting the Win32 installer to work
3816 [William Rowe <wrowe@lnd.com>]
3818 *) Get htpasswd compiling under Windows
3819 [William Rowe <wrowe@lnd.com>]
3821 *) Change the log message for a bind() failure to show the
3822 interface and port number. [Jeff Trawick]
3824 *) Import the documentation from 1.3.12 and bring parts of it
3825 up-to-date with respect to the changes that have occurred
3829 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
3830 now logged correctly on BeOS.
3833 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
3834 Makefile.win includes the same user interface as the old
3836 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
3838 *) Win32 exec now uses COMSPEC environment string for command
3839 shell path resolution.
3840 [William Rowe <wrowe@lnd.com>] PR#3715
3842 *) Win32: ap_connect() was not returning correct error condition
3844 [Allen Prescott <allen@clanprescott.com>]
3846 *) Win32: ap_open() was broken on Win9x because an NT-specific
3847 flag was passed to CreateFile. ap_puts() added an unnecessary
3849 [Jeff Trawick <trawick@us.ibm.com>]
3851 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
3852 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
3853 confusing ee/et name and made all extensions language/dialect
3854 rather than country reflecting. Changed example files to
3855 explicit reflect the ISO charset and added a few common
3856 ones to the example config [dirkx]
3858 *) Extend external module capability. To use this, you call
3859 configure with --with-module=path/to/mod1,path/to/mod2,etc.
3862 *) Backported the various "default charset" fixes from 1.3.12,
3863 including the AddDefaultCharset directive. [Jim Jagielski]
3865 *) Added the capability to do ${ENVVAR} constructs in the
3866 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
3867 it does this on a line by line basis; i.e. if the envvar
3868 expands to something with spaces you have to protect it
3869 by adding quotes around it (Unless of course you expect it
3870 to contains more than one argument. Alternatively you
3871 can compile it on a per token basis; which is what people
3872 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
3873 hampers fancier hacks.
3874 [Dirk-Willem van Gulik]
3876 *) Changed the 'ErrorDocument' syntax in that it NO longer
3877 supports the asymetric
3879 ErrorDocument 301 "Some message
3881 Note the opening " quote, without a closing quote. It now
3882 has either the following syntaxes
3884 ErrorDocument XXX /local/uri
3885 ErrorDocument XXX http://valid/url
3886 ErrorDocument XXX "Some Message"
3888 The recognition heuristic is: if it has a space it
3889 is a message. If it has no spaces and starts with a /
3890 or is a valid URL then treat it that way. Otherwise it
3891 is assumed to be a message.
3893 This breaks backward compatibility but makes live a hell
3894 of a lot easier for GUI's and config file parsers.
3895 [Dirk-Willem van Gulik]
3897 *) Changed 'CacheNegotiatedDocs' from its present/not-present
3898 syntax into a 'on' or 'off' syntax. As it currently is the
3899 only non nesting token which uses NO_ARGS and thus is an
3900 absolute pain for any config interface automation. This
3901 breaks backward compatibility. [Dirk-Willem van Gulik]
3903 *) Add ability to add external modules to the build process. This is
3904 done with --with-module=/path/to/module. Modules can only be added
3905 as static modules at this point.
3908 Changes with Apache 2.0a1
3910 *) Fix FreeBSD 3.3 core dump.
3911 Basically, ap_initialize() needs to get called before
3912 create_process(), since create_process() passes op_on structure
3913 to semop() to get a lock, but op_on isn't initialized until
3914 ap_initialize() calls setup_lock(). Here is a slight
3915 rearrangement to main() which calls ap_initialize() earlier...
3916 [Jeff Trawick <trawick@us.ibm.com>]
3918 *) Enable Apache to use sendfile/TransmitFile API
3919 [Bill Stoddard, David Reid, Paul Reder]
3921 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
3925 *) Make file I/O and network I/O writev/sendv APIs consistent.
3926 Eliminate use of ap_iovec_t and use Posix struct iovec.
3927 Use seperate variable on ap_writev to set the number of iovecs
3928 passed in and number of bytes written.
3931 *) Adapt file iol to use APR functions. Replaced ap_open_file()
3932 with ap_create_file_iol(). ap_create_file_iol() requires that
3933 the file be opened prior to the call using ap_open().
3936 *) Port mod_include and mod_cgi to 2.0
3937 [Paul Reder, Bill Stoddard]
3939 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
3940 bytes_read/bytes_written is always valid (never -1). Plus
3941 some fixes to buff.c to correct problems introduced by the
3942 errno => ap_status_t changes a while back. Plus a fix to
3943 chunked encoding introduced right at the beginning of 2.0.
3946 *) Revamped UNIX build system to use autoconf and libtool.
3947 [Manoj Kasichainula, Sascha Schumann]
3949 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
3951 *) More rigorous checking of Host: headers to fix security problems
3952 with mass name-based virtual hosting (whether using mod_rewrite
3953 or mod_vhost_alias).
3954 [Ben Hyde, Tony Finch]
3956 *) Add back support for UseCanonicalName in <Directory> containers.
3957 [Manoj Kasichainula]
3959 *) Added APLOG_STARTUP log type. This allows us to write an error
3960 message without any of the date and time information. As a part
3961 of this change, I also removed all of the calls to fprintf(stderr
3962 and replaced them with calls to ap_log_error using APLOG_STARTUP
3963 writing to stderr is no longer portable, because we don't direct
3964 stderr to the error log on all platforms.
3967 *) Convert error logging functions to take errno as an argument.
3968 This makes our error logs more portable, because some Windows API's
3969 don't set errno. This change allows us to still output a valid
3970 message on all of our platforms.
3973 *) mod_mime_magic runs in 2.0-dev now.
3974 [Paul Reder <rederpj@raleigh.ibm.com>]
3976 *) sendfile has been added to APR.
3977 [John Zedlewski <zedlwski@Princeton.EDU>]
3979 *) buff.c has been converted to no longer use errno.
3980 [Manoj Kasichainula]
3982 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
3983 interface adaption to APR functions did it. [Martin Kraemer]
3985 *) Support DSOs properly on 32-bit HP-UX 11.0
3986 [Dilip Khandekar <dilip@cup.hp.com>]
3988 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
3989 [Ralf S. Engelschall]
3991 *) Cleaned APR build environment integration and bootstrap APR
3992 automatically for developers from src/Configure.
3993 [Ralf S. Engelschall]
3995 *) Fixed building of src/support/htpasswd.c
3996 [Ralf S. Engelschall]
3998 *) When generating the Location: header, mod_speling forgot
3999 to escape the spelling-fixed uri. (Forw-Port from 1.3)
4002 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
4004 *) Change all pools to APR contexts. This is the first step to
4005 incorporating APR into Apache. [Ryan Bloom]
4007 *) Move "handler not found" warning message to below the check
4008 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
4009 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
4011 *) Support line-continuation feature in config.option file and
4012 allow the loading of multiple option sections at once via
4013 ``--with-option=<section1>,<section2>,...''
4014 [Ralf S. Engelschall]
4016 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
4018 Changes with Apache MPM
4020 *) Use asynchronous AcceptEx() and a completion port to accept and
4021 dispatch connections to threads in Windows NT/2000.
4024 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
4027 *) Implement the APACI --with-option facility
4028 (per default used the config.option file).
4029 [Ralf S. Engelschall]
4031 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
4033 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
4034 Replace pre_connection module call with a register_hook call and
4035 implement pre_connection as a hook. The intent is that these hooks will
4036 be extended to allow Apache to be multi-protocol, and also to allow the
4037 calling order to be specified on a per-hook/per-module basis.
4040 *) Implement mpm_* methods as "modules". Each method gets its own
4041 subdir in src/modules (eg: src/modules/prefork). Selection
4042 of method uses Rule MPM_METHOD. [Jim Jagielski]
4044 *) Port the hybrid server from the apache-apr repository as
4045 mpm_mpmt_pthread. [Manoj Kasichainula]
4047 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
4048 amongst the unix MPMs.
4050 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
4051 signal handling for the new world order. [Dean Gaudet]
4053 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
4054 of alloc.c for now. [Dean Gaudet]
4056 *) Handle partial large writes correctly. [Ben Laurie]
4058 *) Eliminate conn_rec's pointer to server. All it knows is the base server
4059 based on IP/port. [Ben Laurie]
4061 *) Port a bunch of modules to the new module structure.
4062 ["Michael H. Voase" <mvoase@midcoast.com.au>]
4064 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
4066 *) Basic restructuring to introduce the MPM concept; includes various
4067 changes to the module API... better described by
4068 docs/initial_blurb.txt. [Dean Gaudet]
4070 Changes with Apache pthreads
4072 *) New buff option added: BO_TIMEOUT. It describes the timeout for
4073 buff operations (generally over a network).
4074 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
4076 *) Created http_accept abstraction. Added 4 new functions (not exported):
4077 init_accept(), begin_accepting_requests(), get_request(),
4078 stop_accepting_requests() [Bill Stoddard]
4080 *) Fix to ap_rprintf call that allows mod_info to work properly.
4081 [James Morris <jmorris@intercode.com.au>]
4083 *) user and ap_auth_type fields were moved from connection_rec to
4084 request_rec. [Ryan Bloom]
4086 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
4087 needed in a threaded server.
4089 *) Initial pthread implementation from from Dean's apache-nspr code.
4090 [Bill Stoddard, Ryan Bloom]
4093 Changes with Apache 1.3.9
4095 *) Remove bogus error message when a redirect doesn't set Location.
4096 Instead, use an empty string to avoid coredump if the error message
4097 was supposed to include a location. [Roy Fielding]
4099 *) Don't allow configure to include mod_auth_digest unless it is
4100 explicitly requested, even if the user asked for all modules.
4103 *) Translate module names to dll names for OS/2 so that they are no more
4104 than 8 characters long and have an extension of "dll" instead of "so".
4107 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
4108 Fix test-compile check to check for randbyte instead of trand32.
4109 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
4110 and tweak to make Amaya happier. [Ronald Tschalär]
4112 *) Ensure that the installed expat include files are world readable,
4113 just like the other header files. [Martin Kraemer]
4115 *) Fixed generated AddModule adjustments in APACI's `configure' script
4116 in order to allow (new) modules like mod_vhost_alias to be handled
4117 correctly (which was touched by the adjustments for mod_alias).
4118 [Ralf S. Engelschall]
4120 *) For binary builds, add -R flag to apachectl to work around the lack of
4121 an absolute path to the ./libexec directory where the libhttp.ep file
4122 is needed for SHARED_CORE architectures. [Randy Terbush]
4124 *) WIN32: Create the CGI script process as DETACHED. This may solve the
4125 problem observed by some Win95/98 users where they get CGI script
4126 output sent to the console. [Bill Stoddard]
4128 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
4129 routines are now called ap_base64* and are 'plain' (i.e., no
4130 pool access or anything clever). Inside util.c the routines acting
4131 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
4132 The oddly named ap_uuencode(), ap_uudecode() are kept around for
4133 now but deprecated. [dirkx]
4135 *) Clean up the base64 and SHA1 additions and make sure they are
4136 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
4137 files. [Roy Fielding]
4139 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
4140 checking. Allow compiling on VS 6.0. [Randy Terbush]
4142 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
4144 *) Use TestCompile to search for the truerand library (rather than blindly
4145 assuming its existence). If it is not found, complain (but do not
4146 exit - yet). [Martin Kraemer]
4148 *) We forgot to add the new exported function names to
4149 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
4151 *) Add description of -T command-line option to usage().
4152 [Ralf S. Engelschall]
4154 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
4155 searched only AFTER libap has been searched, because libap needs
4156 some symbols from libos. [Martin Kraemer]
4158 *) Fix conflict with original mod_digest related to the symbol of the
4159 module dispatch list (which has to be unique for DSO and follow the
4160 usual conventions for the installation procedure).
4161 [Ralf S. Engelschall]
4163 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
4164 for other platforms as well. [Martin Kraemer]
4166 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
4167 types by AP_LONG and replace reference to renamed variable 'ubuf'
4168 by 'buffer'. [Martin Kraemer]
4170 Changes with Apache 1.3.8 [not released]
4172 *) Flush the output buffer immediately after sending an error or redirect
4173 response, since the result may be needed by the client to abort a
4174 long data transfer or restart a series of pipelined requests.
4175 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
4177 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
4178 [Ian Turner <iant@sequent.com>] PR#4735
4180 *) Local struct mmap in http_core.c conflicted with system structure
4181 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
4183 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
4184 [Ronald Tschalär <ronald@innovation.ch>]
4186 *) Fix a memory leak where the module counts were getting messed
4187 up across restarts. [David Harris <dharris@drh.net>]
4189 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
4190 properly in mod_access.
4191 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
4193 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
4194 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
4196 *) PORT: Support for compaq/tandem/com.
4197 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
4199 *) Added SHA1 password encryption support to easy migration from
4200 Netscape servers. See support/SHA1 for more information.
4201 Caused the separation of ap_md5.c into md5, sha1 and a general
4202 ap_checkpass.c with just a validate_passwd routine. Added a
4203 couple of flags to support/htpasswd. Some reuse of the to64()
4204 function; hence renamed to ap_to64().
4205 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
4207 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
4208 with ASCII/EBCDIC conversions in "ident" query.
4209 [David McCreedy <McCreedy@us.ibm.com>]
4211 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
4212 Change "Power Macintosh" to Power* so if uname prints "Power Book"
4213 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
4215 *) Fix SIGSEGV on some systems because the Vary fix below included
4216 a call to table_do with a variable argument list that was not
4217 NULL terminated. Replaced with better implementation. [Roy Fielding]
4219 Changes with Apache 1.3.7 [not released]
4221 *) The "Vary" response header field is now sanitised right before
4222 the header is sent back to the client. Multiple "Vary" fields
4223 are combined, and duplicate tokens (e.g., "Vary: host, host" or
4224 "Vary: host, negotiate, host, accept-language") are reduced to
4225 single instances. This is a better solution than the force-no-vary
4226 one (which is still valid for clients that can't cope with Vary
4227 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
4229 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
4231 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
4232 least on Linux and FreeBSD for now.
4235 *) Win32: More apache -k restart work. Restarts are now honored
4236 immediately and connections in the listen queue are -not- lost.
4237 This is made possible by the use of the WSADuplicateSocket()
4238 call. The listeners are opened in the parent, duplicated, then
4239 the duplicates are passed to the child. The original listen sockets
4240 are not closed by the parent across a restart, thus the listen queue
4242 [Bill Stoddard <stoddard@raleigh.ibm.com>]
4244 *) Fix handling of case when a client has sent "Expect: 100-continue"
4245 and we are going to respond with an error, but get stuck waiting to
4246 discard the body in the pointless hope of preserving the connection.
4247 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
4249 *) Fix 'configure' to work correctly with SysV-based versions of
4250 'tr' (consistent with Configure's use as well). [Jim Jagielski]
4252 *) apxs: Add "-S var=val" option which allows for override of CFG_*
4253 built-in values. Add "-e" option which works like -i but doesn't
4254 install the DSO; useful for editing httpd.conf with apxs. Fix
4255 editing code so that multiple invocations of apxs -a will not
4256 create duplicate LoadModule/AddModule entries; apxs can now be
4257 used to re- enable/disable a module. [Wilfredo Sanchez]
4259 *) Win32: Update the server to use Winsock 2. Specifically, link with
4260 ws2_32.lib rather than wsock32.lib. This gives us access to
4261 WSADuplcateSocket() in addition to some other enhanced comm APIs.
4262 Win 95 users may need to update their TCP/IP stack to pick up
4263 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
4264 [Bill Stoddard stoddard@raleigh.ibm.com]
4266 *) Win32: Redirect CGI script stderr (script debug info) into the
4267 error.log when CGI scripts fail. This makes Apache on Win32
4268 behave more like Unix.
4269 [Bill Stoddard stoddard@raleigh.ibm.com]
4271 *) Fixed `httpd' usage display: -D was missing.
4272 [Ralf S. Engelschall] PR#4614
4274 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
4275 [Ralf S. Engelschall] PR#4561, PR#4562
4277 *) OS/2: Fix problem with accept lock semaphores where server would die with
4278 "OS2SEM: Error 105 getting accept lock. Exiting!"
4279 [Brian Havard] PR#4505
4281 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
4282 [Randy Terbush <randy@covalent.net>]
4284 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
4285 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
4287 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
4288 command potentially _is_ GCC. [Ralf S. Engelschall]
4290 *) Fix apxs build issues on AIX
4291 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
4293 *) DocumentRoot Checking: Under previous versions, when Apache
4294 first started up, it used to do a stat of each DocumentRoot to
4295 see if it existed and was a directory. If not, then an error
4296 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
4297 does not exist, you will get error messages in error_log. If
4298 the '-t' command line option is used (to check the configuration)
4299 the check of DocumentRoot IS performed. An additional command
4300 line option, '-T', has been added if you want to avoid the
4301 DocumentRoot check even when checking the configuration.
4304 *) Win32: The query switch "apache -S" didn't exit after showing the
4305 vhost settings. That was inconsistent with the other query functions.
4306 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
4308 *) Win32: Changed behaviour of apache -k restart.
4309 Previously, the server would drain all connections in the stack's
4310 listen queue before honoring the restart. On a busy server, this
4311 could take hours. Now, a restart is honored almost immediately.
4312 All connections in Apache's queues are handled but connections in
4313 the stack's listen queue are discarded. Restart triggered by
4314 MaxRequestPerChild is unchanged.
4315 [Bill Stoddard <stoddard@raleigh.ibm.com>]
4317 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
4318 the accept loop. Good for a 5% performance boost. Cleaned up
4319 parent/child process management code.
4320 [Bill Stoddard <stoddard@raleigh.ibm.com>]
4322 *) Added ceiling on file size for memory mapped files.
4323 [John Giannandrea <jg@meer.net>] PR#4122
4325 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
4326 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
4327 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
4329 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
4330 use this at least for Expat. [Ralf S. Engelschall]
4332 *) Allow .module files to specify libraries with Lib:.
4335 *) Allow SetEnvIf[NoCase] to test environment variables as well
4336 as header fields and request attributes. [Ken Coar]
4338 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
4339 content-types are "text/html;parameters". PR#4524 [Ken Coar]
4341 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
4342 never accepted into any standard, and it opens up certain DoS
4343 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
4345 *) TestCompile updated. We can now run programs and output the
4346 results during the Configure process. [ Jim Jagielski]
4348 *) The source is now quad (long long) aware as needed. Specifically,
4349 the Configure process determines the correct size of off_t and
4350 *void. When the OS/platform/compiler supports quads, ap_snprintf()
4351 provides for the 'q' format qualifier (if quads are not available,
4352 'q' is silently "demoted" to long). [Jim Jagielski]
4354 *) When the username or password fed to htpasswd is too long, include the
4355 size limit in the error message. Also report illegal characters
4356 (currently only ':') in the username. Add the size restrictions
4357 to the man page. [Ken Coar]
4359 *) Fixed the configure --without-support option so it doesn't result in
4360 an infinite loop. [Marc Slemko]
4362 *) Piped error logs could cause a segfault if an error occured
4363 during configuration after a restart.
4364 [Aidan Cully <aidan@panix.com>] PR#4456
4366 *) If a "Location" field was stored in r->err_headers_out rather
4367 than r->headers_out, redirect processing wouldn't find it and
4368 the server would core dump on ap_escape_html(NULL). Check both
4369 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
4370 if Location isn't set. [Doug MacEachern, Ken Coar]
4372 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
4373 of the Expat 1.0.2 distribution. [Greg Stein]
4375 *) Replace regexec() calls with calls to a new API stub function
4376 ap_regexec(). This solves problems with DSO modules which use the regex
4377 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
4379 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
4380 environment variables can be set according to the protocol version
4381 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
4383 *) Add DSO support for OpenStep (Mach 4.2) platform.
4384 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
4386 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
4387 [Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
4389 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
4390 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
4392 *) Better DSO flags recognition on NetBSD platforms using ELF.
4393 [Todd Vierling <tv@pobox.com>] PR#4310
4395 *) Always log months in english format for %t in mod_log_config.
4396 [Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
4398 *) Support for server-parsed and multiview-determined ReadmeName and
4399 HeaderName files in mod_autoindex. Removed the restriction on
4400 "/"s in ReadmeName and HeaderName directives since the *sub_req*
4401 routines will deal with the access issues. (It's now possible to
4402 have {site|group|project|customer|...} wide readmes and headers.)
4403 [Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
4406 *) When stat() fails, don't assume anything about the contents of
4407 the struct stat. [Ed Korthof <ed@bitmechanic.com>]
4409 *) It's OK for a semop to return EINTR, just loop around and try
4410 again. [Dean Gaudet]
4412 *) Fix configuration engine re-entrant hangups, which solve a
4413 handful of problems seen with mod_perl <Perl> configuration sections
4414 [Salvador Ortiz Garcia <sog@msg.com.mx>]
4416 *) Mac OS and Mac OS X Server now use the appropriate custom layout
4417 by default when building with APACI; allow for platform-specific
4418 variable defaults in configure. [Wilfredo Sanchez]
4420 *) Do setgid() before initgroups() in http_main; some platforms
4421 zap the grouplist when setgid() is called. This was fixed in
4422 suexec earlier, but the main httpd code missed the change.
4423 [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2579

4428 *) mod_include's fsize/flastmod should allow only relative paths, just
4429 like "include file". [Jaroslav Benkovsky <benkovsk@pha.pvt.cz>]
4431 *) OS/2: Add support for building loadable modules using DLLs.
4434 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
4437 *) Fix minor but annoying bug with the test for Configuration.tmpl
4438 being newer than Configuration so that it is less likely to fail
4439 when using APACI and shadow sources. [Wilfredo Sanchez]
4441 *) PORT: Add initial support for Mac OS (versions 10.0 and
4442 greater). Use Mac OS X Server layout for now. Clean up dyld code
4443 in unix/os.c, and don't install the dyld error handlers, which
4444 are no longer needed in Mac OS. [Wilfredo Sanchez]
4446 *) Rename Rhapsody layout to "Mac OS X Server". Change install
4447 locations to appropriate ones for user-built (as opposed to
4448 system) installs. [Wilfredo Sanchez]
4450 *) Modify mod_autoindex's handling of AddDescription so that the
4451 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
4453 *) Add functionality to the install-bindist.sh script created by
4454 binbuild.sh to use tar when copying distribution files to the
4455 serverroot. This allows upgrading an existing installation
4456 without nesting the new distribution in the old.
4458 install-bindist.sh now detects the local perl5 path to install
4459 apxs and dbmmanage with proper path to perl interpreter.
4461 Add an install-binsupport target which copies the source files
4462 for apxs and dbmmanage to bindist to allow these scripts to
4463 be properly installed relative to the destination serverroot.

4547 redirects. [Jose KAHAN <kahan@w3.org>] PR#3910, 3806, 3575
4549 *) When padding the name with spaces for display, mod_autoindex would

4570 *) Prevent clobbering saved IFS values in APACI. [Jim Jagielski]
4572 *) Fix buffer overflows in ap_uuencode and ap_uudecode pointed out
4573 by "Peter 'Luna' Altberg <peter@altberg.nu>" and PR#3422
4574 [Peter 'Luna' Altberg <peter@altberg.nu>, Ronald Tschalär]
4576 *) Make {Set,Unset,Pass}Env per-directory instead of per-server.
4579 *) Correct an apparent typo: on the Windows and MPE platforms, the
4580 htpasswd utility was limiting passwords to only 8 characters.
4583 *) EBCDIC platforms: David submitted patches for two bugs in the
4584 MD5 digest port for EBCDIC machines:
4585 a) the htdigest utility overwrote the old contents of the digest file
4586 b) the Content-MD5 header value (ContentDigest directive) was wrong
4587 when the returned file was not converted from EBCDIC, but was a
4588 binary (e.g., image file) in the first place.
4589 [David McCreedy <mccreedy@us.ibm.com>]
4591 *) support/htpasswd now permits the password to be specified on the
4592 command line with the '-b' switch. This is useful when passwords
4593 need to be maintained by scripts -- particularly in the Win32
4594 environment. [Ken Coar]
4596 *) Win32: Win32 multiple services patch. Added capability to install and
4597 run multiple copies of apache as individual services.
4600 apache -n apache1 -i -f c:/httpd.conf
4601 Installs apache as service 'apache1' and associates c:/httpd.conf
4604 Starts apache1 service.
4606 Stops apache1 service
4609 apache -n apache2 -i
4610 Installs apache as service 'apache2'. httpd.conf is located under
4611 the default server root (/apache/conf/httpd.conf).
4613 Starts apache2 service.
4616 apache -n apache3 -i -d c:/program files/apache
4617 Install apache as service 'apache3' and sets server root to
4618 c:/program files/apache.
4621 apache -n apache2 -k restart
4622 Restart apache2 service
4624 [Keith Wannamaker, Ken Parzygnat, Bill Stoddard]
4626 *) Correct the signed/unsigned character handling for the MD5 routines;
4627 mismatches were causing compilation problems with gcc -pedantic and
4628 in the TPF cross-compilation. [Ken Coar]
4630 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
4631 a roughly 5 fold speed up. [Brian Havard]
4633 *) proxy ftp: instead of using the hardwired string "text/plain" as
4634 a fallback type for files served by the ftp proxy, use the
4635 ap_default_type() function to determine the configured type.
4636 This allows for special configurations like
4637 <Directory proxy:ftp://some.host>
4638 DefaultType gargle/blurb
4640 Additionally, add the Content-Encoding: header to FTP proxy replies
4641 when the encoding is defined (by the AddEncoding directive).
4642 Because it was missing, it was almost impossible to browse compressed
4643 files using the FTP proxy (works now perfectly in Communicator).
4644 The ftp proxy now also returns the Date: and Server: header lines (if not
4645 much else... This code is "somewhat" broken) like normal requests do.
4648 *) Be more smart in APACI's configure script when determining the UID/GID
4649 for User/Group directives and use the determined UID/GID to initialize
4650 the permissions on the proxycachedir.
4651 [Dirk-Willem van Gulik, Ralf S. Engelschall]
4653 *) Changed the forking-prior-to-cleanup in the proxy module to first
4654 check wether it actually needs to collect garbage. This reduces
4655 the number of fork()s from one/request to just the odd one an hour.
4656 [Dirk-Willem van Gulik]
4658 *) Added proxy, auth and header support to src/support/ab.c. Added a
4659 README file to src/support/

4665 *) Add support for DSO module compilation on BSD/OS 3.x.
4666 [Randy Terbush, Covalent Technologies]
4668 *) Fix sed-substitutions in `make install': path elements like `httpd/conf'
4669 (for instance from an APACI configure --sysconfdir=/etc/httpd/conf
4670 option) were substituted with $(TARGET).conf, etc. Same for other strings
4671 with dots where the dot wasn't matched as plain text.

4679 Changes with Apache 1.3.6
4681 *) Removed new PassAllEnv code due to DSO problems. [Lars Eilebrecht]
4683 Changes with Apache 1.3.5 [not released]
4685 *) M_INVALID needed a value within the scope of METHODS so that unknown
4686 methods can be access controlled. [Roy Fielding] PR#3821
4688 *) Added PassAllEnv; makes server's entire environment available
4689 to CGIs and SSIs executed within directive's scope. [Ken Coar]
4691 *) ap_uuencode() always added two trailing '='s and encoding of
4692 8 bit characters on a machine with signed char may produced
4693 incorrect results. Additionally ap_uuencode() should now
4694 work correctly on EBCDIC platforms.
4695 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
4697 *) WIN32: Binary installer now runs the configuration DLL before
4698 the reboot prompt (which is only given if MSVCRT.DLL system
4699 DLL is new or updated). This should avoid the configuration
4700 directory being empty after installation. [Paul Sutton]
4701 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988
4703 *) WIN32: Binary installer now creates Start menu options to start
4704 and stop Apache as a console application and to uninstall
4705 the Apache service on NT. [Paul Sutton] PR#3741
4707 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
4709 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
4710 have been reported with flock() locking (probably related to kernel
4711 version). [Dean Gaudet] PR#2723, 3531
4713 *) Using APACI, the main config file (usually httpd.conf) was
4714 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez
4715 <wsanchez@apple.com>]
4717 *) PORT: AIX does not require the SHARED_CODE "hack"
4718 [Ryan Bloom <rbb@raleigh.ibm.com>]

4724 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
4725 for 8-bit safeness. [Dean Gaudet]
4727 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
4728 because SPARCs have a small machine-specific maximum size for the Global
4729 Offset Table which is often exceeded when compiling one of the larger
4730 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
4732 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
4733 DSO/DLL section because it's a directive from mod_status and isn't
4734 available before the DLL of mod_status is loaded.
4735 [Martin POESCHL <mpoeschl@gmx.net>] PR#3936
4737 *) SECURITY: Fix a bug in the calculation of the buffer size for the line

4746 really support all future gcc versions >= 2.7 until we know more.
4747 [John Tobey <jtobey@banta-im.com>] PR#3983
4749 *) Let APACI's configure script correctly complain for unknown --enable-XXX
4750 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
4752 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
4753 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
4754 possible buffer overflows. [Ralf S. Engelschall]
4756 *) Remove no longer used non-API function ap_single_module_init().
4757 [Ralf S. Engelschall]
4759 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
4762 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
4763 to make platform installations easier. [Wilfredo Sanchez]
4765 *) In configure, do not append the target name to the directory path if
4766 the path already contains "apache". [Ralf S. Engelschall]
4768 *) SIGPIPE is now ignored by the server core. The request write routines
4769 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
4770 correctly check for output errors and mark the connection as aborted.
4771 Replaced many direct (unchecked) calls to ap_b* routines with the
4772 analogous ap_r* calls. [Roy Fielding]
4774 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
4775 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
4776 Furthermore map lookups for non-existent keys are now cached as well.
4777 Additionally "txt" maps are now parsed with simple string functions
4778 instead of using ap_pregcomp(). As a side effect a bug that prevented
4779 the usage of keys containing the "," character was fixed.
4780 The changes drastically improve the performance when large rewrite maps
4782 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
4784 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
4785 other than GET, and const'd the definition of method in request_rec.
4788 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
4790 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
4791 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
4793 *) Add %V to mod_log_config, this logs the hostname according to the
4794 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
4795 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
4797 *) Add support for \n and \t to mod_log_config, can be used to produce
4798 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
4800 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
4802 *) Added informative error messages for failed munmap() and fseek() calls
4803 in http_core.c. [John Bley, Roy Fielding]
4805 *) Added some informative error messages for some failed malloc()
4806 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
4808 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
4809 is removed. This allows <Directory proxy:*> directives to work and
4810 prevents invalid requests from killing the process.
4811 [Brian Havard <brianh@kheldar.apana.org.au>]
4813 *) Reorganised FAQ document.
4814 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497
4816 *) src/support/: The ApacheBench benchmark program was overhauled by
4817 David N. Welton: you can now have it generate an HTML TABLE, presumably
4818 for integration into other HTML sources. David updated the ab man page
4819 as well and added some missing descriptions. Thanks!
4820 [David N. Welton <davidw@prosa.it>]
4822 *) Win32: The filename validity checker now allows filenames containing
4823 characters in the range 0x80 to 0xff (for example accented characters).
4824 [Paul Sutton] PR#3890
4826 *) Added conditional logging based upon environment variables to
4827 mod_log_config. mod_log_referer and mod_log_agent
4828 are now deprecated. [Ken Coar]
4830 *) Allow apache acting as a proxy server to relay the real
4831 reason of a failure to a client rather than the "internal
4832 server error" it does currently. The general exposure mechanism
4833 can be triggered by any module by setting the "verbose-error-to"
4834 note to "*"; this allows more than just proxy errors to be exposed.
4835 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
4837 *) Moved man pages for ab and apachectrl to section 8.
4838 [Wilfredo Sanchez, Roy Fielding]
4840 *) Added -S option to install.sh so that options can be passed to
4841 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
4843 *) Tweak modules Makefile generated by Configure so that it handles
4844 the test case of no modules being selected. [chaz@reliant.com]
4846 *) Added a <LimitExcept method ...> sectioning directive that allows
4847 the user to assign authentication control to any HTTP method that
4848 is *not* given in the argument list; i.e., the logical negation
4849 of the <Limit> directive. This is particularly useful for controlling
4850 access on methods unknown to the Apache core, but perhaps known by
4851 some module or CGI script. [Roy Fielding, Tony Finch]
4853 *) Prevent apachectl from complaining if the PIDFILE exists but
4854 does not contain a process id, as might occur if the server is
4855 being rapidly restarted. [Wilfredo Sanchez]
4857 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
4859 *) Entity tag comparisons for If-Match and If-None-Match were not being
4860 performed correctly -- weak tags might cause false positives. Also,
4861 strong comparison wasn't properly enforced in all cases.
4862 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
4864 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
4867 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
4868 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
4870 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
4871 to util.c for parsing an HTTP header field value to extract the next
4872 list item, taking into account the possible presence of nested comments,
4873 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
4874 insignificant whitespace and lowercases non-quoted tokens.
4875 [Roy Fielding] PR#2065
4877 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
4878 code different from 500. This allows the proxy to, e.g., return
4879 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
4881 *) Fix ordering of language variants for the case where the traditional
4882 negotiation algorithm is being used with multiple language variants
4883 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
4885 *) Do not round the TCN quality calculation to 5 decimal places,
4886 unlike RFC 2296, because the calculation might need 12 decimal places
4887 to get the right result. [Roy Fielding]
4889 *) Remove unused code to disable transparent negotiation when
4890 negotiating on encoding only, as we now handle encoding too
4891 (though this is nonstandard for TCN), remove charset=ISO-8859-1
4892 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
4893 some debugging statements within mod_negotiation. [Koen Holtman]
4895 *) Fixed a rare memory corruption possibility in mod_dir if the index
4896 file is negotiable and no acceptable variant can be found.
4897 [Dean Gaudet, Roy Fielding, Martin Kraemer]
4899 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
4900 searching the Win32 registry for script interpreters.
4903 *) Win32: The compiled-in default filename for the error log is now
4904 error.log, which matches the default in the distributed httpd.conf.
4907 *) Win32: Any error messages from -i or -u command line options are now
4908 displayed on the console output rather than sent to the error log.
4909 Also the "Running Apache..." message is not output unless Apache is
4910 going to serve requests. [Paul Sutton]
4912 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
4913 and use a private significator ('$apr1$') to mark passwords as
4914 being smashed with our own algorithm. Also abstract the password
4915 checking into a new ap_validate_password() routine. [Ken Coar]
4917 *) Win32: The filename validity checker now allows "COM" but refuses
4918 access to "COM1" through "COM4". This allows filenames such
4919 as "com.name" to be served. [Paul Sutton] PR#3769.
4921 *) BS2000: Adapt to the new ufork() system call interface which will
4922 make subtasking easier on the OSD/POSIX mainframe environment.
4925 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
4926 ap_compat.h. [David White <david@persimmon.com>] PR#3725
4928 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
4929 use `.db' instead of `.pag' not only for FreeBSD, but also when
4930 the NDBM library looks like Berkeley-DB based.
4931 [Ralf S. Engelschall] PR#3773
4933 *) Add ability to handle DES or MD5 authentication passwords.
4934 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
4936 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
4938 *) SECURITY: Avoid some buffer overflow problems when escaping
4939 quoted strings. (This overflow was on the heap and we believe
4940 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
4942 *) Let src/Configure be aware of CFLAGS options starting with plus
4943 signs as it's the case for the HP/UX compiler.
4944 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
4946 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
4947 and check to see if the tar we wind up with supports '-h'.
4948 [Jim Jagielski] PR#3671
4950 *) A consistent and conservative style for all shell scripts has been
4951 implemented. Basically, all shell string tests use the traditional
4952 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
4953 to protect against bare null variable strings (ie: wrapping both
4954 sides with double quotes and prepending 'x'). 'x' was chosen
4955 because it's more universal and hopefully easier for old shell
4956 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
4959 *) The status module now prints out both the main server generation as
4960 well as the generation of each process. Also, the vhost info is
4961 printed with '?notable'. [Jim Jagielski]
4963 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
4964 and this makes its functions available to things in src/support.
4967 Changes with Apache 1.3.4
4969 *) Renamed macros status_drops_connection to ap_status_drops_connection
4970 and vestigial scan_script_header to ap_scan_script_header_err,
4971 mostly for aesthetic reasons. [Roy Fielding]
4973 *) The query switch "httpd -S" didn't exit after showing the
4974 vhost settings. That was inconsistent with the other query functions.
4977 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
4978 filename to the end of the STANDARD_MODULE_STUFF. Its
4979 presence at the beginning prevented reporting of the filename
4980 for modules compiled before 1 January 1999. [Ken Coar]
4982 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
4983 to detect and prevent access to special DOS device file names.
4984 [Paul Sutton, Ken Parzygnat]
4986 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
4987 and Makefile_win32_debug.txt (debug build) that work on Win95.
4988 Run each of the following from the src directory:
4989 nmake /f Makefile_win32.txt # compiles normal build
4990 nmake /f Makefile_win32.txt install # compiles and installs
4991 nmake /f Makefile_win32.txt clean # removes compiled junk
4992 nmake /f Makefile_win32_debug.txt # compiles debug build
4993 nmake /f Makefile_win32_debug.txt install
4994 nmake /f Makefile_win32_debug.txt clean
4997 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
4998 to build binary distributions. [Lars Eilebrecht]
5000 *) IndexOptions SuppressColumnSorting only turned off making
5001 the column headers anchors; you could still change the display
5002 order by manually adding a '?N=A' or similar query string to the
5003 URL. Now SuppressColumnSorting locks in the sort order so
5004 it can't be overridden this way. [Ken Coar]
5006 *) Added IndexOrderDefault directive to supply a default sort order
5007 for FancyIndexed directory listings. [Ken Coar] PR#1699
5009 *) Change the ap_assert macro to a variant that works on all platforms.
5010 [Richard Prinz <richard.prinz@cso.net>] PR#2575
5012 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
5013 search for an underscore on dlsym() (as it's already the case
5014 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
5016 *) Small fix for mod_env.html: The module was documented as to be _not_
5017 compiled into Apache per default, although it _IS_ compiled into
5018 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
5020 *) Instead of fixing a bug in the generation procedure for config.status (a
5021 backslash was missing) we remove the bug together with it's complete
5022 context because the special cases of the past can now no longer occur
5023 because of the recent magic for the --with-layout default.
5024 [Ralf S. Engelschall] PR#3590
5026 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
5027 making sure the src/support/ tools are _forced_ to be build last (they
5028 depend on other libraries).
5029 [Markus Theissinger <markus.theissinger@gmx.de>]
5031 *) Fix installation procedure: Now that os-inline.c is actually used (a
5032 recently fixed bug prevented this) we need to also install os-include.c
5033 in addition to os.h into the PREFIX/include/ location or building of
5034 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
5036 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
5037 allow us to distinguish between a garbled DSO (or even a file which isn't
5038 an Apache module DSO at all) and a DSO which doesn't match the current
5039 Apache API. [Ralf S. Engelschall] PR#3152
5041 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
5042 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
5043 match case insensitive (this especially avoids nasty patterns like
5044 `[tT][eE][sS][tT]'). Second two additional internal map functions
5045 `escape' and `unescape' were added which can be used to escape/unescape
5046 to/from hex-encodings in URLs parts (this is especially useful in
5047 combination with map lookups).
5048 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
5050 *) Renamed the macro escape_uri() to ap_escape_uri() which was
5051 forgotten (because it was a macro) in the symbol renaming process.
5052 [Ralf S. Engelschall]
5054 *) Fix some inconsistencies related to the scopes of directives. The only
5055 user visible change is that the directives `UseCanonicalName' and
5056 `ContentDigest' now use the (more correct) `Options' scope instead of
5057 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
5059 *) Using DSO, the Server token was being mangled. Specifically, the
5060 module's token was being added first before the Apache token. This
5061 has been fixed. [Jim Jagielski]
5063 *) Major overhaul of mod_negotiation.c, part 2.
5064 - properly handle "identity" within Accept-Encoding.
5065 - allow encoded variants in RVSA negotiation and let them appear in
5066 the Alternates field using the non-standard "encoding" tag-list.
5067 - fixed both negotiation algorithms so that an explicitly accepted
5068 encoding is preferred over no encoding if "identity" is not
5069 included within Accept-Encoding.
5070 - added ap_array_pstrcat() to alloc.c for efficient concatenation
5071 of large substring sequences.
5072 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
5075 *) Major overhaul of mod_negotiation.c, part 1.
5076 - cleanups to mod_negotiation comments and code structure
5077 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
5078 support for everything in the upcoming HTTP/1.1
5079 revision (draft-ietf-http-v11-spec-rev-06.txt).
5080 - language tag matching also handles tags with more than 2
5082 - empty Accept, Accept-Language, Accept-Charset headers are
5083 processed correctly; previously an empty header would make all
5084 values acceptable instead of unacceptable.
5085 - allowed for q values in Accept-Encoding
5086 - added support for transparent content negotiation (rfc2295 and
5087 rfc2296) (though we do not implement all features in these drafts,
5088 e.g. no feature negotiation). Removed old experimental version.
5089 - implemented 'structured entity tags' for better cache correctness
5090 (structured entity tags ensure that caches which can deal with Vary
5091 will (eventually) be updated if the set of variants on the server
5093 - this involved adding a vlist_validator element to request_rec
5094 - this involved adding the ap_make_etag() function to the global API
5095 - modified guessing of charsets used by Apache negotiation algorithm
5096 to guess 'no charset' if the variant is not a text/* type
5097 - added code to sort multiviews variants into a canonical order so that
5098 negotiation results are consistent across backup/restores and mirrors
5099 - removed possibility of a type map file resolving to another type map
5100 file as its best variant

5127 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
5130 *) Update APXS manual page: some -q option arguments were missing
5131 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
5133 *) Cleanup the command line options: `-?' was documented to show
5134 the usage list but does it with an error because `?' is not a valid
5135 command. OTOH a lot of users expect `-h' to print such a usage list and
5136 instead are annoyed for ages by our huge unreadable list of directives.
5137 So we now changed the command line options this way:
5139 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
5140 very similar to the popular linker option.
5142 Intent: while -l gives the small list of modules, -L now gives the
5143 large list of directives implemented by these modules. This is also
5144 consistent with -v (short version info) and -V (large version info).
5146 Intent: it's now the expected option ;-)
5147 The manual page was adjusted accordingly.

5150 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
5151 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
5153 *) Removed recently introduced bugs and disfigurements in APACI:
5154 o fixed argument line processing: using $args was broken: It was not
5155 initialized and using args="$args $apc_option" and even args="$args
5156 \"$apc_option\"" fails in the second processing round for any arguments
5157 containing whitespaces. The only correct way is to use the construct
5158 "$@" (but not possible here) or iterate _both_ times over the implicit
5159 argument line (no argument to for-loop) which is what we now use.
5160 o make --with-layout=Apache the default without creating
5161 redundancy (copying the --with-layout block in the argument parsing
5162 loop). We achieve this by using the "$@" construct together with the
5163 `set' command to prepend --with-layout=Apache to the command line in
5164 case --with-layout is not used.
5165 o fixed auto-suffix handling now that config.layout exists.
5166 Paths which are auto-suffixed are marked with a trailing plus sign in
5167 config.layout and every path now can be marked this way (not only the
5168 four paths for which we do it currently). Additionally the suffix is
5169 no longer a static one. Instead it's now `/<target>' where <target> is
5170 the argument of the --target option or per default `httpd'.
5171 o allow also tabs (and only spaces) where we match whitespaces
5172 o various fixes and cleanups related to used shell coding style
5173 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
5174 o trimmed output of --help to fit into 80 columns

5200 differenciate between modules when one module name was a postfix of
5201 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
5202 just XXX (think about totally non-standard names like "apache_ssl", too).

5236 *) Fixed possible (but harmless in practice) bug in the DBM lookup
5237 procedure of mod_rewrite: very long keys were truncated.
5238 [Ralf S. Engelschall]
5240 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
5241 identifier, currently "Apache" and "GNU" are pre-defined in the file
5242 config.layout. Custom layouts are possible by using FILE:ID as the
5243 argument where the layout ID is taken from FILE.
5245 The config.layout file consists of <Layout ID>..</Layout> sections
5246 where inside those sections "path_variable: path_value" pairs can be
5247 specified. These lines are converted to path_variable='path_value'.
5249 *) Add a DefaultLanguage directive so that files missing a language
5250 extension (e.g., .fr, .de) can be labelled as being some other
5251 default language. DefaultLanguage can appear in <Directory> and
5252 <Files> containers as well as .htaccess files. [Paul Sutton]

5531 *) PORT: Allow GuessOS to recognize Unixware 7.0.1 [Steve Cameron
5532 <steve.cameron@compaq.com>]
5534 *) Reconstructed the loop through multiple htaccess file names so
5535 that missing files are not confused with unreadable files.
5538 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
5539 errno on an error, which leads to one error being mistaken for
5540 another when reading non-existent .htaccess files.
5543 *) OS/2: The new header tests get things right, need to update
5544 ap_config.h. [Brian Havard]
5546 *) The Perl %ENV hash will now be setup by default when using the
5547 mod_include `perl' command [Doug MacEachern]

5561 Changes with Apache 1.3.2
5563 *) Fix bug in ap_remove_module(), which caused problems for dso's
5564 who were the top_module. [Doug MacEachern]
5566 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
5567 mod_auth_db to both be friendly to users who wants to use this version
5568 and to avoid problems under platforms where only version 2.x is present.
5569 [Dan Jacobowitz <drow@false.org>, Ralf S. Engelschall]
5571 *) When using ap_log_rerror(), make the error message available to the
5572 *ERROR_NOTES envariables by default. [Ken Coar]
5574 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
5575 You now must define a BS2000Account name for the server User.
5576 This has fewer security implications than the old approach.
5579 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
5580 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
5581 platform to make the braindead HPUX linker happy. Notice, for the module
5582 DSOs we don't have to use this, because these are loaded manually (and
5583 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
5585 *) Remove 64 thread limit on Win32.
5586 [Bill Stoddard <stoddard@raleigh.ibm.com>]
5588 *) Remove redundant substitutions in top-level Makefile.tmpl.
5589 [Ralf S. Engelschall]
5591 *) Fix APACI's `Group' configuration adjustment - especially for Linux
5592 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
5594 *) Make PrintPath work generically instead of having one version
5595 strictly for OS/2. [Jim Jagielski, Brian Havard]
5597 *) Fix the recently introduced C header file checking: We now use the C
5598 pre-processor pass only (and no longer the complete compiler pass) to
5599 determine whether a C header file exists or not. Because only this way
5600 we're safe against inter-header dependencies (which caused horrible
5601 portability problems). The only drawback is that we now have a CPP
5602 configuration variable which has to be determined first (we do a similar
5603 approach as GNU Autoconf does here). When all fails the user still has
5604 the possibility to override it manually via APACI or src/Configuration.
5605 As a fallback for the header check itself we can directly check the
5606 existance of the file under /usr/include, too.
5607 [Ralf S. Engelschall] PR#2777
5609 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined
5610 as an alternate mechanism for mmap'd shared memory for RHAPSODY.
5611 ap_private_extern defined to hide symbols that conflict with loaded
5612 dynamic libraries on the NEXT and RHAPSODY platforms.

5637 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
5638 platform, because it's only supported under version 4.0 and higher. But
5639 because our GuessOS is still unaware of Digital UNIX versions and the
5640 -msym is just to optimize the DSO statup time a little bit it's safe and
5641 best when we leave it out now. [Ralf S. Engelschall] PR#2969
5643 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
5644 functions: First all three functions no longer fail on strings containing
5645 "%" chars and second ap_log_printf() no longer does a double-formatting
5646 (instead it directly passes through the message to be formatted to the
5647 real internal formatting function). [Ralf S. Engelschall] PR#2941
5649 *) Allow "Include" directives anywhere in the server config
5650 files (but not .htaccess files). [Ken Coar] PR#2727
5652 *) The proxy was refusing to serve CONNECT requests except to
5653 port 443 (https://) and 563 (snews://). The new AllowCONNECT
5654 directive allows the configuration of the ports to which a
5655 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
5657 *) mod_expires will now act on content that is not sent from a file
5658 on disk. Previously it would never add an Expires: header to
5659 any response that did not come from a file on disk; the only
5660 case where it still doesn't (and can't) add one for that type of
5661 content is if you are using a modification date based setting.
5662 [Marc Slemko, Paul Phillips <paulp@go2net.com>]
5664 *) Problems encountered during .htaccess parsing or CGI execution
5665 that lead to a "500 Server Error" condition now provide explanatory
5666 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
5669 *) Add NameWidth keyword to IndexOptions directive so that the
5670 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
5673 *) Recognize lowercase _and_ uppercase `uname' results under
5674 SCO OpenServer. [David Coelho <drc@ppt.com>]
5676 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
5677 a common problem of (mis-administrated?) IIS servers, make the apache
5678 proxy immune to these errors (and ignore the duplicates, but log
5679 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
5681 *) The <IfModule and <IfDefine block starting directives now only
5682 allow exactly one argument. Previously, the optional negation
5683 character '!' could be separated by whitespace without a syntax
5684 error being reported, albeit defeating the IfModule functionality
5685 (enclosed directives would ALWAYS be executed). By using the
5686 stricter syntax, these hard-to-track errors can be avoided.
5689 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
5690 cause the standalone FancyIndexing directive to logically OR
5691 into any existing IndexOptions settings rather than wiping
5692 them out. [Ken Coar]
5694 *) Changes in ftp proxy: make URL parsing simpler by using the
5696 + Add display of the "current directory" in cases where it's
5697 different from the supplied path (e.g., ftp://user@host/ lives
5698 in /home/user, not in /, therefore clicking on "../" in the
5699 starting directory might send us to /home/).
5700 + When ftp login fails, (esp. when a user name was part of the
5701 URL already), we now return [401 Unauthorized ] to allow the
5702 browser to pop up an authorization dialog. This makes passwords
5703 slightly less visible (they don't appear in the regular log files)
5704 and implements a functionality that other www proxy servers
5708 *) Triggered by the recent "Via:" header changes, the proxy module would
5709 dump core for replies with invalid headers (e.g., duplicate
5710 "HTTP/1.0 200 OK" lines). These errors are now logged and the
5711 core dump is avoided. Also, broken replies are not cached.
5712 [Martin Kraemer] PR#2914
5714 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
5715 plop gmon.out profile data for each child [Doug MacEachern]
5717 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
5718 config.status script to be immune against arguments with whitespaces.
5719 [Yves Arrouye <yves@apple.com>] PR#2866
5721 *) Replace the inlined information grabbing stuff for the configuration
5722 adjustment feature (no --without-confadjust) with calls to a new helper
5723 script `buildinfo.sh' which is both more flexible and already proofed to
5724 be more robust against platform differences. This mainly fixes the
5725 recently occured ``sed: command garbled: ...'' problems.
5726 [Ralf S. Engelschall] PR#2776, PR#2848
5728 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
5729 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
5730 without complains after we recently added the POST feature.
5731 [Ralf S. Engelschall]
5733 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
5734 modules as API functions and we forgot them at the big symbol renaming.
5735 [Ralf S. Engelschall]
5737 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html
5738 [Youichirou Koga <y-koga@jp.FreeBSD.ORG>] PR#2895
5740 *) Dynamically size the filename column of mod_autoindex output.
5743 *) Add the ability to do POST requests to the ab benchmarking tool.
5744 [Kurt Sussman <kls@best.com>] PR#2871
5746 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
5747 5 to 10 because there are some users out there who always have 5 to 8
5748 variables in one RewriteRule and had to patch mod_rewrite.h for every
5749 release. So 15 should be now more than enough, even for them. (I never
5750 needed more than 4 in my RewriteRules ;-)
5751 [Ralf S. Engelschall]
5753 *) Make the proxy generate and understand Via: headers
5756 *) Change the proxy to use tables instead of array_headers for
5757 the header lines. [Martin Kraemer]
5759 *) Make sure the config.status file is not overridden when just
5760 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
5762 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
5763 provide a way to trace API changes that add functionality but do
5764 not create a compatibility issue for precompiled modules, etc.
5765 See include/ap_mmn.h for more details. [Randy Terbush]
5767 *) Fix suexec installation under `make install root=xxx' situation.
5768 [Ralf S. Engelschall]
5770 *) Extend the output of the -V switch to include the paths of all
5771 compiled-in configuration files, if they were overridden at
5772 compile time, for least astonishment of the user.
5775 *) When READing a request in ExtendedStatus mode, the "old"
5776 vhost, request and client information is not displayed.
5779 *) STATUS is no longer available. Full status information now
5780 run-time configurable using the ExtendedStatus directive.
5783 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
5784 cpu time attacks) in header parsing. Add ap_overlap_tables(),
5785 a function which can be used to perform bulk update operations
5786 on tables in a more efficient manner. [Dean Gaudet]
5788 *) SECURITY: Added compile-time and configurable limits for
5789 various aspects of reading a client request to avoid some simple
5790 denial of service attacks, including limits on maximum request-line
5791 size (LimitRequestLine), number of header fields (LimitRequestFields),
5792 and size of any one header field (LimitRequestFieldsize). Also added
5793 a configurable directive LimitRequestBody for limiting the size of the
5794 request message body. [Roy Fielding]
5796 *) Make status module aware of DNS and logging states, even if
5797 STATUS not defined. [Jim Jagielski]
5799 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
5801 *) Enhance mod_speling so that CheckSpelling can be used in
5802 <Directory> containers and .htaccess files. [Ken Coar]
5804 *) API: new ap_custom_response() function for hooking into the
5805 ErrorDocument mechanism at runtime [Doug MacEachern]
5807 *) API: new ap_uuencode() function [Doug MacEachern]
5809 *) API: scan_script_header_err_core() now "public" and renamed
5810 ap_scan_script_header_err_core() [Doug MacEachern]
5812 *) The 'status' module will now show the process pid's and their
5813 state even without full STATUS accounting. [Jim Jagielski]
5815 *) Restore the client IP address to the error log messages, this
5816 was lost during the transition from 1.2 to 1.3. Add a new
5817 function ap_log_rerror() which takes a request_rec * and
5818 formats it appropriately. [Dean Gaudet] PR#2661
5820 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
5821 whitespace in input lines -- including within quoted strings.
5823 but leading and trailing whitespace should continue to be
5824 stripped [Martin Kraemer]
5826 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
5827 the ugly use of an env. variable and use command-line args for
5828 alternate $PATH. Make more like advanced 'type's as well.
5831 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
5832 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
5833 <alain.st-denis@ec.gc.ca>] PR#2736
5835 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
5837 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
5838 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
5839 directory was renamed to src/os/os2/ for consistency.
5840 [Brian Havard, Ralf S. Engelschall]
5842 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
5843 files (here modules) against other DSO files (here shared libraries).
5844 This is done by determining a subset of LIBS which can be safely used for
5845 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
5846 disabled for all platforms to avoid problems with this (experimental)
5847 rule. But we provide it now for those people how ran into problems and
5848 want to came out by forcing linking against DSOs.
5849 [Ralf S. Engelschall] PR#2587
5851 *) Fix suEXEC start message: Has to be of `notice' level to really get
5852 printed together with the standard startup message because the `notice'
5853 level is handled special inside ap_log_error() for startup messages.
5854 [Ralf S. Engelschall] PR#2761 PR#2761 PR#2765
5856 *) Add correct `model' MIME types from RFC2077 to mime.types file.

5859 *) Fixed examples in mod_rewrite.html document.
5860 [Youichirou Koga <y-koga@jp.FreeBSD.org>, Ralf S. Engelschall] PR#2756
5862 *) Allow ap_read_request errors to propagate through the normal request
5863 handling loop so that the connection can be properly closed with
5864 lingering_close, thus avoiding a potential TCP reset that would
5865 cause the client to miss the HTTP error response. [Roy Fielding]
5867 *) One more portability fix for APACI shadow tree support: Swap order of awk
5868 and sed in top-level configure script to avoid sed fails on some
5869 platforms (for instance SunOS 4.1.3 and NCR SysV) because of the
5870 non-newline-termined output of Awk. [Ralf S. Engelschall] PR#2729

5873 [MATSUURA Takanori <t-matsuu@protein.osaka-u.ac.jp>]
5875 *) Fix a segfault in the proxy on OS/2. [Brian Havard]
5877 *) Fix Win32 part of ap_spawn_child() by providing a reasonable child_info
5878 structure instead of just NULL. This fixes at least the RewriteMap
5879 programs under Win32. [Marco De Michele <mdemichele@tin.it>] PR#2483

5892 *) Fix `install-includes' sub-target of `install' target in top-level
5893 Makefile.tmpl: The umask+cp approach didn't work as expected (especially
5894 for users which extracted the distribution under 'umask 077'), so replace
5895 it by an explicit cp+chmod approach.
5896 [Richard Lloyd, Curt Sampson, Ralf S. Engelschall] PR#2656 PR#2626

5900 [Ralf S. Engelschall]
5902 *) Use a more straight forward and thus less problematic Sed command in
5903 src/helper/mkdir.sh script. [Ralf S. Engelschall]

5923 situations to prevent pollution of system locations with Apache files.
5924 [Ralf S. Engelschall] PR#2660
5926 *) Fixed problem with buffered response message not being sent for
5927 the read_request error conditions of URI-too-long (414) and
5928 malformed header fields (400). [Roy Fielding] PR#2646
5930 *) Add support for the Max-Forwards: header line required by RFC2068 for
5931 the TRACE method. This allows apache to TRACE along a chain of proxies
5932 up to a predetermined depth. [Martin Kraemer]
5934 *) Fix SHARED_CORE rule: The CFLAGS_SHLIB variable is no longer doubled
5935 (compilers complained) and the .so.V.R.P filename extension was adjusted
5936 to correctly reflect the 1.3.2 version.

5974 *) Global renaming of C header files to both get rid of conflicts with third
5975 party packages and to again reach consistency:
5976 1. conf.h -> ap_config.h
5977 2. conf_auto.h -> ap_config_auto.h \ these are now merged
5978 3. ap_config.h -> ap_config_auto.h / in the config process
5979 4. compat.h -> ap_compat.h
5980 5. apctype.h -> ap_ctype.h
5981 Backward compatibility files for conf.h and compat.h were created.
5983 *) mod_mmap_static will no longer take action on requests unless at
5984 least one "mmapfile" directive is present in the configuration.
5985 This experimental module has to do some black magic to operate
5986 inside the current API and thus creates side-effects for other
5987 modules under some circumstances.

5999 *) Autogenerate some HAVE_XXXXX_H defines in conf_auto.h (determined via
6000 TestCompile) instead of defining them manually in conf.h based on less
6001 accurate platform definitions. This way we no longer have to fiddle with

6044 *) The APACI libexecdir was not extended with an "apache/" subdir
6045 if the installation prefix didn't already contain "apache", but
6046 it should be because the DSO files are Apache-specific. Now
6047 libexecdir is treated the same way sysconfdir, datadir, localstatedir
6048 and includedir are already treated.

6104 these are treated by Win32 as if they are ".." but are not detected by
6105 other machinery within Apache. This is something of a kludge but
6106 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
6108 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
6109 pools and thus pollutes libap (until the pool stuff is moved there).

6123 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
6124 remove some of the classical hurdles for new users when setting up

6126 user. Package authors can use the --without-confadjust option to disable
6127 these configuration adjustments.
6128 [Ralf S. Engelschall]
6130 *) Added an EXTRA_DEPS configuration parameter which can be used
6131 to add an extra Makefile dependency for the httpd target, for instance
6132 to external third-party libraries, etc.

6136 as <IfModule>..</IfModule> sections) which can be used to skip or process
6137 contained commands dependend of ``-D PARAMETER'' options on the command
6138 line. This can be used to achieve logical conditions like <IfDefine
6139 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)

6152 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
6153 in top-level configure script to avoid sed fails on some platforms (for
6154 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
6155 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
6157 *) Improve performance of directory listings (mod_autoindex) by comparing
6158 integer keys (last-modified and size) as integers rather than converting
6159 them to strings first. Also use a set of explicit byte tests rather
6160 than strcmp() to check for parent directory-ness of an entry. Oh, and
6161 make sure the parent directory (if displayed) is *always* listed first
6162 regardless of the sort key. Overall performance winnage should be good
6163 in CPU time, instruction cache, and memory usage, particularly for large
6164 directories. [Ken Coar]
6166 *) Add a tiny but useful goody to APACI's configure script: The generation
6167 of a config.status script (as GNU Autoconf does) which remembers the used
6168 configure command and hence can be used to restore the configuration by
6169 just re-running this script or for remembering the configuration between
6171 [Ralf S. Engelschall]
6173 *) Add httpd -t (test) option for running configuration syntax tests only.
6174 If something is broken it complains and exits with a return code
6175 non-equal to 0. This can be used manually by the user to check the Apache
6176 configuration after editing and is also automatically used by apachectl
6177 on (graceful) restart command to make sure Apache doesn't die on restarts
6178 because of a configuration which is now broken since the last (re)start.
6179 This way `apachectl restart' can be used inside cronjobs without having
6180 to expect Apache to be falling down. Additionally the httpd -t can be run
6181 via `apachectl configtest'.

6321 spawn_child was obsoleted and moved to compat.h
6324 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
6325 programs: ap_spawn_child_err() is used and the Win32 case now uses
6326 CreateProcess() instead of a low-level execl() (which caused problems in
6327 the past under Win32).
6328 [Ralf S. Engelschall]
6330 *) A few cosmetics and trivial enhancements to APXS to make the
6331 generated Makefile more user friendly. [Ralf S. Engelschall]
6333 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
6334 was updated to use the normal apache error processing, thereby allowing
6335 proxy errors to be treated by ErrorDocument's as well. For this
6336 purpose, a new module-to-core communication variable "error-notes"
6337 was introduced; the proxy (and possibly other modules) communicates
6338 its error text using this variable. Its content is copied to a new
6339 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
6340 The old proxy special error routine ap_proxy_log_uerror()
6341 was replaced by regular ap_log_error() calls, many messages were made

6345 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
6348 *) Transform the configure message "You need root privileges for suEXEC"
6349 from a fatal error into a (more friendly) warning because the building
6350 ("make") of Apache we can allow, of course. Root privileges are needed
6351 only for the installation step ("make install"). So make sure the
6352 user is aware of this fact but let him proceed as long as he can.

6414 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
6416 *) The proxy cache would store an incorrect content-length in the cached

6418 of the original copy instead of using the cached copy.
6419 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
6421 *) The Makefiles assumed that DSO files are build via $(LD). This
6422 is broken for two reasons: First we never defined at least LD=ld
6423 somewhere to make sure this works (it was silently assumed that most Make
6424 provide a built-in LD definition - ARGL!) and second using the generic LD
6425 variable is not the truth. Instead a special variable named LD_SHLIB is
6426 reasonable because although "ld" is usually the default, the command for
6427 building DSO files can be "libtool" or even "cc" on some systems.
6428 [Ralf S. Engelschall]
6430 *) Replace the AddVersionPlatform directive with ServerTokens which
6431 provides for more control over the format of the Server:
6432 header line. SERVER_SUBVERSION is no longer supported;
6433 all module should use the ap_add_version_component()
6434 API function instead. [Jim Jagielski]

6440 not retrieved in src/Configure and thus was not useable.
6441 [Ralf S. Engelschall]
6443 *) Various Makefile consistency cleanups:
6444 - make OSDIR also automatically be relative to src/ like INCDIR
6445 - SUBDIRS is now generated in src/Makefile only and not in
6446 Makefile.config because it is a local define for this location.
6447 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
6448 any Makefile but make sure that at least the "-K inline" is kept in
6450 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
6451 - updated the dependencies theirself
6452 - removed not existing SHLIB variable from "clean" targets
6453 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
6454 already exists and OBJS_PIC are also just plain objects and have not
6455 directly to do with "shared" things. The only difference is that they
6456 contain PIC. So OBJS_PIC is the more canonical name.
6457 - Updated the Makefile-dependency lines for OBJS_PIC
6458 - Removed the Makefile-dependency line in Configure to avoid double
6460 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
6461 of xxx.lo as GNU libtool does with its PIC objects
6462 - reduce local complexity in modules Makefile.tmpl by moving the last
6463 existing target "depend" to the generation section in Configure, too.
6464 - removed the historical $(SPACER) which was used in the past together
6465 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
6466 is no longer needed.
6467 - force the build and run of the gen_xxx programs under main/ as the
6468 first step before building the objects because it looks cleaner
6469 [Ralf S. Engelschall]
6471 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
6474 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
6477 *) WIN32: Don't force ISAPI headers to finish with \n.
6478 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
6480 *) When opening "configuration" files (like httpd.conf, htaccess
6481 and htpasswd), Apache will not allow them to be non-/dev/null
6482 device files. This closes a DoS hole. At the same time,
6483 we use ap_pfopen to open these files to handle timeouts.
6484 [Jim Jagielski, Martin Kraemer]
6486 *) Apache will now log the reason its httpd children exit if they exit
6487 due to an unexpected signal. (It requires a new porting define,
6488 SYS_SIGLIST, which if defined should point to a list of text
6489 descriptions of the signals available. See PORTING.) [Dean Gaudet]
6491 *) WIN32: chdir() doesn't make sense in a multithreaded environment
6492 like WIN32. Before, Win32 CGI's could have had sporadic failures
6493 if a chdir call from one thread was made between another chdir call
6494 and a spawn in another thread. So, for now don't chdir for CGI scripts
6495 in WIN32. The current CGI "spec" is unclear as to whether it's
6496 necessary. Long-term fix is to either serialize the chdir/spawn combo
6497 or use WIN32 native calls to spawn a process. This temp fix was
6498 necessary to remove this as a showstopper for 1.3's release.
6501 *) Cleanup the suEXEC support in APACI and make it more safe:
6502 1. Add big fat hint in INSTALL about risks and to read the
6503 htdocs/manual/suexec.html document before using the suexec-related
6505 2. Make sure the user has at least provided one --suexec-xxxx option
6506 (specifies suEXEC parameters) in addition to --enable-suexec option.
6507 If only --enable-suexec is given APACI stops with a hint to INSTALL
6508 and htdocs/manual/suexec.html documents.
6509 3. Provide two additional --suexec-xxxx options to make the suEXEC
6510 configuration complete (especially for package maintainers who else
6511 had to patch the source tree) by providing ways to configure minimal
6512 UID/GID and safe PATH, too.
6513 [Ralf S. Engelschall]
6515 *) Cleanup of the `configure --shadow' process:
6516 - make sure the configure script creates its temporary files in the
6517 shadow tree to avoid conflicts with parallel configure runs
6518 - removed unnecessary option "-r" from "rm" call for Makefiles
6519 - make sure the configure scripts creates the shadow-wrapper Makefile
6520 only when no shadow trees already exists
6521 - make sure "make distclean" removes the shadow-wrapper Makefile but only
6522 when no more shadow trees exists
6523 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
6524 as fast (in the past it needed 70sec, now it runs just 38sec)
6525 - make sure CVS does not complain about the created files
6526 Makefille.<gnutriple> and directories src.<gnutriple>
6527 [Ralf S. Engelschall]
6529 *) Added the ap_add_version_component() API routine and the
6530 AddVersionPlatform core directive. The first allows modules to
6531 declare themselves in the Server response header field value,
6532 augmenting the SERVER_SUBVERSION define in the Configuration file
6533 with run-time settings (more useful in a loadable-module environment).
6534 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
6535 into the server version string. [Ken Coar] PR#2056
6537 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
6540 *) Emit the "Accept-Range" header for the default handler.
6541 [Brian Behlendorf] PR#1464
6543 *) Add a note to httpd.conf-dist that apache will on some systems fail
6544 to start when the Group # is set to a negative or large positive value.
6547 *) Make sure the module execution order is correct even when some modules
6548 are loaded under runtime (`LoadModule') via the DSO mechanism:
6549 1. The list of loaded modules is now a dynamically allocated one
6550 and not the original statically list from modules.c
6551 2. The loaded modules are now correctly setup by LoadModule for
6552 later use by the AddModule command.
6553 3. When the DSO mechanism for modules is used APACI's `install'
6554 target now enables all created `LoadModule' lines per default because
6555 this is both already expected by the user _and_ needed to avoid
6556 confusion with the next point and reduces the Makefile.tmpl complexity
6557 4. When the DSO mechanism for modules is used, APACI's `install'
6558 target now additionally makes sure the module list is reconstructed
6559 via a complete `ClearModuleList+AddModule...' entry.
6560 5. The support tool `apxs' now also makes sure an AddModule command
6561 is added in addition to the LoadModule command.
6562 6. The modules.c generation was extended to now contain two
6563 comments to make sure no one is confused by the confusing terminology
6564 of loading/linking (we use load=link+load & link=activate instead of
6565 the obvious load=activate & link=link :-( )
6566 This way now there is no longer a difference under execution time between
6567 statically and dynamically linked modules.

6570 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
6571 Big Symbol Renaming. [Ralf S. Engelschall]
6573 *) Add a comment to mod_example.c showing the format of a FLAG command
6576 *) Standardized the time format in mod_status to match that of other
6577 places in the code (e.g. DATE_GMT). PR#1551
6579 *) Fix handling of %Z in timefmt strings for those platforms with no time
6580 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
6583 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
6584 feature compatible with 'UseCanonicalName off' by changing
6585 r->server->server_hostname to ap_get_server_name(). And I changed some
6586 functions which use r->server->port to use ap_get_server_port() instead,
6587 because if there's no Port directive in the config r->server->port is 0.
6590 *) get/set_module_config are trivial enough to be better off inline. Worth
6591 1.5% performance boost. [Dean Gaudet]
6593 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
6594 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
6597 *) [BS2000 security] BS2000 needs an extra authentication to initialize
6598 the task environment to the unprivileged User id. Otherwise CGI scripts
6599 would have a way to gain super user access. [Martin Kraemer]
6601 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
6602 absolute path, only log base name of logging source as is done
6603 in unix. [Martin Kraemer]
6605 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
6606 the encoding type from the Accept-Encoding header (if it's there)
6607 and use it in the response, as that's probably what it'll be expecting.
6608 [Ronald.Tschalaer@psi.ch]
6610 *) Fix to mod_alias: translate_alias_redir is dealing with
6611 a URI, not a filename, so the check for drive letters for win32

6614 *) WIN32: Allow .cmd as an executable extension.

6620 *) Child processes can now "signal" (by exiting with a status
6621 of APEXIT_CHILDFATAL) the parent process to abort and
6622 shutdown the server if the error in the child process was
6623 fatal enough. [Jim Jagielski]

6626 [Jim Jagielski] PR#2112
6628 *) Make sure the referer_log and agent_log entries in the default httpd.conf

6632 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
6634 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
6637 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
6638 Additionally the checks for finding the vendor DSO library were moved
6639 from mod_so.c to Configure because first it needs $PLAT etc. and second
6640 mod_so already uses an abstraction layer and does not fiddle with the
6641 vendor functions itself.
6642 [Jens-Uwe Mager, Ralf S. Engelschall]
6644 *) PORT: Some optimization defines for NetBSD
6645 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
6647 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
6648 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
6650 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
6651 AIX variants should work fine, too. Even AIX 3.x should work). This is
6652 accomplished by using the free DSO emulation code from Jens-Uwe Mager
6653 which we put into a os/unix/os-dso-aix.c file.
6654 [Ralf S. Engelschall]
6656 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
6657 that we should use NET_SIZE_T == int but the include files force size_t.
6658 [Ralf S. Engelschall]
6660 *) Fix two bugs in select() handling in http_main.c.
6663 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
6664 is unset (as it is in situations like timeouts) where it is unclear
6665 whether errno is set or not. [Martin Kraemer]
6667 *) Just having APACI's localstatedir is too general and not enough for most
6668 of the systems. 1.3b6 again required manual APACI patches by package
6669 maintainers from RedHat and FreeBSD because for their filesystem layout a
6670 little bit more flexibility in configuring the paths is needed. Hence we
6671 provide three additional configure options (--runtimedir, --logfiledir,
6672 --proxycachedir) which now can be used for more granular adjustments if
6673 --localstatedir is not enough to fit the particular needs. As a nice
6674 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
6675 [Ralf S. Engelschall]
6677 *) Make the install root for "make install" in APACI's Makefile overrideable
6678 by package authors. This way we are even more friendly to package
6679 maintainers (especially Debian and RedHat) who build for the real prefix
6680 via "configure --prefix=/<real>" but use a different local prefix via
6681 "make root=/tmp/apache install" for rolling the package without bristling
6682 the target location on their system.
6683 [Ralf S. Engelschall]
6685 *) Workaround sed limitations in APACI's configure script by now
6686 substituting in chunks of 50 commands (because for instance HPUX's vendor
6687 sed has a limit of max. 98 commands)

6696 [Ralf S. Engelschall]
6698 *) Workaround braindead AWK's when generating ap_config.h: The split() and
6699 substr() functions cannot be nested under vendor AWK from Solaris 2.6.

6703 o fix IFS handling for _nested_ situation
6704 o fix Perl interpreter search: take first one found instead of last one
6705 o fix DSO consistency check
6706 o print error messages to stderr instead of stdout
6707 o add install-quiet for --shadow situation to Makefile stub
6708 o reduce complexity by avoiding sed-hacks for rule and module list loops

6711 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
6713 *) Make sure the input field separator (IFS) shell variable is explicitly
6714 initialized correctly before _every_ `for' loop and also restored after
6715 the loops. [Ralf S. Engelschall]
6717 *) Make sure that "make install" doesn't overwrite the `mime.types' and
6718 `magic' files from an existing Apache installation. Because people often
6719 customize these for own MIME and content types.

6757 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
6759 *) If you start apache with the -S command line option it will dump

6761 to figure out what is wrong with their vhost configuration.
6762 (Other dumps may be added in the future.) [Dean Gaudet]
6764 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
6765 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
6768 *) Because /usr/local/apache is the default prefix the ``configure
6769 --compat'' option no longer has to set prefix, again. This way the
6770 --compat option honors a leading --prefix option. [Lars Eilebrecht]
6772 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
6773 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
6774 to avoid "discard const" warnings. [Ralf S. Engelschall]
6776 *) If a specific handler is set for a file yet the request still
6777 ends up being handled by the default handler, log an error
6778 message before handling it. This catches things such as trying
6779 to use SSIs without mod_include enabled. [Marc Slemko]
6781 *) Fix error logging for the startup case where ap_log_error() still uses
6782 stderr as the target. Now the default log level is honored here, too.
6783 [Ralf S. Engelschall]

6790 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
6792 Changes with Apache 1.3b6
6794 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
6796 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
6797 interface via the similar but proprietary HP/UX shl_xxx-style system
6798 calls. [Ralf S. Engelschall]
6800 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
6801 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
6802 Make. [Ralf S. Engelschall]
6804 *) ++++ THE BIG SYMBOL RENAMING ++++
6805 To avoid symbol clashes with third-party code compiled into the server,
6806 we globally applied the prefix "ap_" to the following classes of
6808 - Apache provided general functions (e.g., ap_cpystrn)
6809 - Public API functions (e.g., palloc, bgets)
6810 - Private functions which we can't make static (because of
6811 cross-object usage) but should be (e.g., new_connection)
6812 For backward source compatibility a new header file named compat.h was
6813 created which provides defines for the old symbol names and can be used
6814 by third-party module authors.
6817 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
6818 problem under SVR4 is that there is no command flag to force the linker
6819 to export the global symbols of the httpd executable therewith they are
6820 available to the DSO's. Instead of problematic hacks like creating a
6821 dummy.so file (containing dummy references to all global symbols) the
6822 httpd binary is linked against, we use a clean trick stolen from Perl 5:
6823 Placing the Apache core code itself into a DSO library named libhttpd.so.
6824 This way the global symbols _HAVE_ to be exported and thus are available
6825 to any manually loaded DSO's under runtime. To reduce the impact to the
6826 user to null we go even further and create a stub httpd executable which
6827 automatically keeps track of the DSO library loading itself and thus
6828 hides the complete mechanism from the user. Although the generation of
6829 this DSO library is automatically triggered for platforms which
6830 essentially need it (mostly all SVR4-derivates) it can be also enabled
6831 manually via the Rule SHARED_CORE. This can be interesting in the future
6832 where we perhaps exploit this libhttpd.so mechanism for providing nifty
6833 features like graceful upgrades, or whatever.
6834 [Ralf S. Engelschall, Martin Kraemer]
6836 *) Build the libraries before building the rest of the tools. [Ben Hyde]
6838 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
6839 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
6840 conventions while "clean" removes only stuff created by "all" targets,
6841 "distclean" additionally removes the stuff from the configuration
6842 process. This way "make distclean" (hence the name) provides a fresh
6843 source tree as it was for distribution.
6844 [Ralf S. Engelschall]
6846 *) Allow top-level (APACI) Makefile to break on build errors
6847 the same way the src/ subtree Makefiles breaks on them by replacing the
6848 initial APACI sed-subdir-display-kludge with a more clean
6849 variable-passing-solution: variable SDP can optionally hold the subdir
6850 prefix which is consistently used for displaying the subdir movement.
6851 This way even the top-level Makefile can stop correctly on errors as the
6852 user expects. [Ralf S. Engelschall]
6854 *) Fixed ordering of argument checks for RewriteBase directive.
6855 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
6857 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
6858 indicating that a module is being compiled for dynamic loading. Also
6859 remove #define IS_MODULE from modules and add SHARED_MODULE define
6860 to the mak/dsp files. [Alexei Kosut]
6862 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
6863 since we are now logging APLOG_WARNING by default. [Roy Fielding]
6865 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
6867 *) Add documentation file and src/Configuration.tmpl entry for the
6868 experimental mod_mmap_static module. Because although it is and marked as
6869 an experimental one it is distributed and thus should be documented and
6870 prepared for configuration the same way as all others modules.
6871 [Ralf S. Engelschall]
6873 *) Add query (-q) option to apxs support tool to be able to manually query
6874 specific settings from apxs. This is needed for instance when you
6875 manually want to access Apache's header files and you need to assemble
6876 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
6877 [Ralf S. Engelschall]
6879 *) Now src/Configure uses a fallback strategy for the shared object support
6880 on platforms where no explicit information is available: If a Perl
6881 installation exists we ask it about its shared object support and if it's
6882 the dlopen-style one we shamelessly guess the compiler and linker flags
6883 for creating shared objects from Perls knowledge. Of course, the user is
6884 warning about what we are doing and informed that he should send us
6885 the guessed flags when they work. [Ralf S. Engelschall]
6887 *) Provide APACI --without-support option to be able to disable the build
6888 and installation of the support tools from the src/support/ area.
6889 Although its useful to have these installed per default we should provide
6890 a way to compile and install without them for backward-compatibility.
6891 [Ralf S. Engelschall]
6893 *) Add of the new APache eXtenSion (apxs) support tool for building and
6894 installing modules into an _already installed_ Apache package through the
6895 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
6896 this approach actually doesn't need the Apache source tree. The
6897 (APACI-installed) server package is enough, because this now includes the
6898 Apache C header files (PREFIX/include) and the new APXS tool
6899 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
6900 module authors to build their Apache modules _OUTSIDE_ the Apache source
6901 tree while avoiding them to fiddle around with the totally platform
6902 dependend way of compiling DSO files. The tool supports all ranges of
6903 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
6904 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
6905 on-the-fly generate a minimalistic Makefile and sample module for the
6906 first step to provide both a quick success event and to demonstrate the
6907 APXS mechanism to module authors. [Ralf S. Engelschall]
6909 *) Fix core dumps in use of CONNECT in proxy.
6910 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
6912 *) Modify the log directives in httpd.conf-dist files to use CustomLog
6913 so that users have examples of how CustomLog can be used.
6916 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
6917 the Apache distribution tree. Until Apache 1.3 there was no real
6918 out-of-the-box batch-capable build and installation procedure for the
6919 complete Apache package. This is now provided by a top-level "configure"
6920 script and a corresponding top-level "Makefile.tmpl" file. The goal is
6921 to provide a GNU Autoconf-style frontend which is capable to both drive
6922 the old src/Configure stuff in batch and additionally installs the
6923 package with a GNU-conforming directory layout. Any options from the old
6924 configuration scheme are available plus a lot of new options for flexibly
6925 customizing Apache. [Ralf S. Engelschall]
6927 *) The floating point ap_snprintf code wasn't threadsafe.

6937 Configure knows which CC we are using. [Jim Jagielski]
6939 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
6940 was defined in a parent directory. [Lars Eilebrecht]
6942 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
6943 a generic printf-style routine that can call arbitrary output
6944 routines. Use this to replace http_bprintf.c. Add new routines
6945 psprintf(), pvsprintf() which allocate the exact amount of memory
6946 required for a string from a pool. Use psprintf() to clean up
6947 various bits of code which used ap_snprintf()/pstrdup().
6950 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
6951 ap_snprintf() has different semantics and formatting codes than
6952 snprintf(). [Dean Gaudet]
6954 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
6955 is necessary on at least Solaris where the /etc/rc?.d scripts
6956 are run with these signals ignored, and "SIG_IGN" settings are
6957 maintained across exec().

6985 *) Allow %2F in two situations: 1) it is in the query part of the URI,
6986 therefore not exposed to %2F -> '/' translations and 2) the request
6987 is a proxy request, so we're not dealing with a local resource anyway.
6988 Without this, the proxy would fail to work for any URL's with
6989 %2f in them (occurs quite often in

7009 name was really too generic, added documentation for this directive to
7010 the mod_proxy.html and corrected the hyperlink to it in the
7011 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
7013 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
7014 faster [Martin Kraemer]
7016 *) Make Configure die when you give it an unknown command switch.
7019 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
7020 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
7021 and per default compiled support programs have manual pages - just to
7022 document our stuff a little bit more and to be able to do really
7023 Unix-like installations ;-) [Ralf S. Engelschall]
7025 *) Major cleanups to the Configure script to make it and its generated
7026 Makefiles again readable and maintainable: add SRCDIR option, removed
7027 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
7028 generated sections, consequently added Makefile headers with inheritance
7029 information, added subdir movement messages for easier following where
7030 the build process currently stays (more verbose then standard Make, less
7031 verbose than GNU make), same style to comments in the Configure script,
7032 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
7034 *) Add the new ApacheBench program "ab" to src/support/: This is derived
7035 from the ZeusBench benchmarking program and can be used to determine the
7036 response performance of an Apache installation. This version is
7037 officially licensed with Zeus Technology, Ltd. See the license agreement
7038 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
7039 [Ralf S. Engelschall]
7041 *) API: Various core functions that are definately not part of the API
7042 have been made static, and a few have been marked API_EXPORT. Still
7043 more have been marked CORE_EXPORT and are not intended for general
7044 use by modules. [Doug MacEachern, Dean Gaudet]
7046 *) mod_proxy was not clearing the Proxy-Connection header from
7047 requests; now it does. This did not violate any spec, however
7048 causes poor interactions when you are talking to remote proxies.
7049 [Marc Slemko] PR#1741
7051 *) Various cleanups to the command line interface and manual pages.
7052 [Ralf S. Engelschall]
7054 *) cfg_getline() was not properly handling lines that did not end
7055 with a line termination character. [Marc Slemko] PR#1869, 1909
7057 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
7059 *) Clean up some undocumented behavior of mod_setenvif related to
7060 "merging" two SetEnvIf directives when they match the same header
7061 and regex. Document that mod_setenvif will perform comparisons in
7062 the order they appear in the config file. Optimize mod_setenvif by
7063 doing more work at config time rather than at runtime.
7066 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
7067 to allow for modules to overrule them and to reduce redefinition
7068 warnings [Jim Jagielski]
7070 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
7073 *) Making the hard-coded cross-module function call mime_find_ct() (from
7074 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
7075 checking is really called even for proxy requests except for URLs with
7076 HTTP schemes (because there we can optimize by not running the type
7077 checking hooks due to the fact that the proxy gets the MIME Content-type
7078 from the remote host later). This change cleans up mod_mime by removing
7079 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
7080 especially unbundles mod_proxy and mod_mime. This way they both now can
7081 be compiled as shared objects and are no longer tied together.
7082 [Ralf S. Engelschall]
7084 *) util.c cleanup and speedup. [Dean Gaudet]
7086 *) API: Clarification, pstrndup() will always copy n bytes of the source
7087 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
7089 *) Mark module command_rec and handler_rec structures const so that they
7090 end up in the read-only data section (and are friendlier to systems
7091 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
7093 *) Add check to the "Port" directive to make sure the specified
7094 port is in the appropriate range. [Ben Hyde]
7096 *) Performance improvements to invoke_handler().
7097 [Dmitry Khrustalev <dima@bog.msu.su>]
7099 *) Added support for building shared objects even for library-style modules
7100 (which are built from more than one object file). This now provides the
7101 ability to build mod_proxy as a shared object module. Additionally
7102 modules like mod_example are now also supported for shared object
7103 building because the generated Makefiles now no longer assume there is at
7104 least one statically linked module. [Ralf S. Engelschall]
7106 *) API: Clarify usage of content_type, handler, content_encoding,
7107 content_language and content_languages fields in request_rec. They
7108 must always be lowercased; and the strings pointed to shouldn't
7109 be modified (you must copy them to modify them). Fix a few bugs
7110 related to this. [Dean Gaudet]
7112 *) API: Clarification: except for RAW_ARGS, all command handlers can
7113 treat the char * parameters as permanent, and modifiable. There
7114 is no need to pstrdup() them. Clean up some needless pstrdup().
7117 *) Now mod_so keeps track of which module shared objects with which names
7118 are loaded and thus avoids multiple loading and unloading and irritating
7119 error_log messages. [Ralf S. Engelschall]
7121 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
7122 environment variable in the apache core. But that tweaking interferes
7123 with mod_setenv. So don't tweak if the user has specified an explicit
7124 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
7126 *) rputs() did not calculate r->sent_bodyct properly.
7127 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
7129 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
7130 name, or left unset if this value is unavailable. Apache was setting
7131 it to the IP address when unavailable.
7132 [Tony Finch <fanf@demon.net>] PR#1925
7134 *) Various improvements to the configuration and build support for compiling
7135 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
7136 OSF1 support with GCC and vendor compilers was added. This way shared
7137 object support is now provided out-of-the-box for FreeBSD, Linux,
7138 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
7139 [Ralf S. Engelschall]
7141 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
7142 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
7143 and USE_OS2_SCOREBOARD. [Dean Gaudet]
7145 *) Fix one more special locking problem for RewriteMap programs in
7146 mod_rewrite: According to the documentation of flock(), "Locks are on
7147 files, not file descriptors. That is, file descriptors duplicated
7148 through dup(2) or fork(2) do not result in multiple instances of a lock,
7149 but rather multiple references to a single lock. If a process holding a
7150 lock on a file forks and the child explicitly unlocks the file, the
7151 parent will lose its lock.". To overcome this we have to make sure the
7152 RewriteLock file is opened _AFTER_ the childs were spawned which is now
7153 the case by opening it in the child_init instead of the module_init API
7154 hook. [Ralf S. Engelschall] PR#1029
7156 *) Change to Location and LocationMatch semantics. LocationMatch no
7157 longer lets a single slash match multiple adjacent slashes in the
7158 URL. This change is for consistency with RewriteRule and
7159 AliasMatch. Multiple slashes have meaning in URLs that they do
7160 not have in (some) filesystems. Location on the other hand can
7161 be considered a shorthand for a more complicated regex, and it
7162 does match multiple slashes with a single slash -- which is
7163 also consistent with the Alias directive.
7164 [Dean Gaudet] related PR#1440
7166 *) Fix bug with mod_mime_magic causing certain files, including files
7167 of length 0, to result in no response from the server.
7170 *) The Configure script now generates src/include/ap_config.h which
7171 contains the set of defines used when Apache is compiled on a platform.
7172 This file can then be included by external modules before including
7173 any Apache header files in case they are being built separately from
7174 Apache. Along with this change, a couple of minor changes were
7175 made to make Apache's #defines coexist peacefully with any autoconf
7176 defines an external module might have. [Rasmus Lerdorf]
7178 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
7179 but without any RewriteXXXXX directives. Here mod_rewrite is given no
7180 chance by the API to initialize its per-server configuration and thus
7181 receives the wrong one from the main server. This is now avoided by
7182 remembering the server together with the config structure while
7183 configuring and later assuming there is no config when we see a
7184 difference between the remembered server and the one calling us.
7185 [Ralf S. Engelschall] PR#1790
7187 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
7188 is automatically disabled under configure time when the dbm_xxx functions
7189 are not available. Second, two heavy source code errors in the DBM
7190 support code were fixed. This makes DBM RewriteMap's usable again after
7191 a long time of brokenness. [Ralf S. Engelschall] PR#1696
7193 *) Now all configuration files support Unix-style line-continuation via
7194 the trailing backslash ("\") character. This enables us to write down
7195 complex or just very long directives in a more readable way. The
7196 backslash character has to be really the last character before the
7197 newline and it has not been prefixed by another (escaping) backslash.
7198 [Ralf S. Engelschall]
7200 *) When using ProxyPass the ?querystring was not passed correctly.
7201 [Joel Truher <truher@wired.com>]
7203 *) To deal with modules being compiled and [dynamically] linked
7204 at a different time from the core, the SERVER_VERSION and
7205 SERVER_BUILT symbols have been abstracted through the new
7206 API routines apapi_get_server_version() and apapi_get_server_built().
7209 *) WIN32: Preserve trailing slash in canonical path (and hence
7210 in PATH_INFO). [Paul Sutton, Ben Laurie]
7212 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
7213 depending on the rev of Solaris and what mixture of modules
7214 are in use. So it has been disabled, and Solaris is back to
7215 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
7216 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
7217 up static content only servers. Or it may fail unpredictably.
7218 [Dean Gaudet] PR#1779, 1854, 1904
7220 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
7223 *) API: Rewrite of absoluteURI handling, and in particular how
7224 absoluteURIs match vhosts. Unless a request is a proxy request, a
7225 "http://host" url is treated as if a similar "Host:" header had been
7226 supplied. This change was made to support future HTTP/1.x protocols
7227 which may require clients to send absoluteURIs for all requests.
7229 In order to achieve this change subtle changes were made to the API. In a
7230 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
7231 that the unmodified uri can be retrieved easily. r->proxyreq is not set
7232 by the core, modules must set it during the post_read_request or
7233 translate_names phase.
7235 Plus changes to the virtualhost test suite for absoluteURI testing.
7237 This fixes several bugs with the proxy proxying requests to vhosts
7238 managed by the same httpd.
7241 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
7242 code from mod_rewrite. The vhost matching is now performed by a
7243 globally available function matches_request_vhost(). [Dean Gaudet]
7245 *) Reduce memory usage, and speed up ServerAlias support. As a
7246 side-effect users can list multiple ServerAlias directives
7247 and they're all considered.

7256 *) Add the `%a' construct to LogFormat and CustomLog to log the client IP
7257 address. [Todd Eigenschink <eigenstr@mixi.net>] PR#1885
7259 *) API: A new source module main/util_uri.c; It contains a routine
7260 parse_uri_components() and friends which breaks a URI into its component
7261 parts. These parts are stored in a uri_components structure called
7262 parsed_uri within each request_rec, and are available to all modules.
7263 Additionally, an unparse routine is supplied which re-assembles the URI
7264 components back to an URI, optionally hiding the username:password@ part
7265 from ftp proxy requests, and other useful routines. Within the structure,
7266 you find on a ready-for-use basis:
7267 scheme; /* scheme ("http"/"ftp"/...) */
7268 hostinfo; /* combined [user[:password]@]host[:port] */
7269 user; /* user name, as in http://user:passwd@host:port/ */
7270 password; /* password, as in http://user:passwd@host:port/ */
7271 hostname; /* hostname from URI (or from Host: header) */
7272 port_str; /* port string (integer representation is in "port") */
7273 path; /* the request path (or "/" if only scheme://host was given) */
7274 query; /* Everything after a '?' in the path, if present */
7275 fragment; /* Trailing "#fragment" string, if present */
7276 This is meant to serve as the platform for *BIG* savings in
7277 code complexity for the proxy module (and maybe the vhost logic).
7280 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
7281 ${map:key}) available for all location where a string is created in
7282 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
7283 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
7284 possible expansions are consequently usable at all string creation
7285 locations. [Ralf S. Engelschall]
7287 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
7288 and not 1) and the per-virtual-server merging of directives. Now all
7289 directives except `RewriteEngine' and `RewriteOption' are either
7290 completely overridden (default) or completely inherited (when
7291 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325
7293 *) Fix `RewriteMap' program lookup in situations where such maps are
7294 defined but disabled (`RewriteEngine off') in per-server context.
7295 [Ralf S. Engelschall] PR#1431
7297 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause
7298 server to bind to port 0 rather than 80. [Dean Gaudet]
7300 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
7301 (like SunOS and FreeBSD) which don't accept the locking of pipes
7302 directly. A new directive RewriteLock is introduced which can be used to
7303 setup a separate locking file which then is used for synchronization.

7309 value is stored by running "apache -i -d serverroot". [Paul Sutton]

7318 *) The mod_setenvif BrowserMatch backwards compatibility command did not
7319 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
7321 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
7322 type but with a special post-processing for the looked-up value: It
7323 parses it into alternatives according to `|' chars and then only one
7324 particular alternative is chosen randomly (this is an essential
7325 functionality needed for balancing between backend-servers when using
7326 Apache as a Reverse Proxy. The looked up value here is a list of
7327 servers). Second, `int' with the built-in maps named `tolower' and
7328 `toupper' which can be used to map URL parts to a fixed case (this is an
7329 essential feature to fix the case of server names when doing mass
7330 virtual-hosting with the help of mod_rewrite instead of using
7331 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
7332 Jay Soffian <jay@cimedia.com>] PR#1631
7334 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
7335 This directive lets Apache adjust the URL in Location-headers on HTTP
7336 redirect responses sent by the remote server. This way the virtually
7337 mapped area is no longer left on redirects and thus by-passed which is
7338 especially essential when running Apache as a reverse proxy.

7502 calls that use too small an initial guess, see alloc.c.
7505 *) Options and AllowOverride weren't properly merging in the main
7506 server setting inside vhosts (only an issue when you have no
7507 <Directory> or other section containing an Options that affects
7508 a request). Options +foo or -foo in the main_server wouldn't
7509 affect the main_server's lookup defaults. [Dean Gaudet]
7511 *) Variable 'cwd' was being used pointlessly before being set.
7514 *) r->allowed handling cleaned up in the standard modules.
7517 *) Some case-sensitivity issues cleaned up to be consistent with
7518 RFC2068. [Dean Gaudet]
7520 *) SIGURG doesn't exist everywhere.
7521 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
7523 *) mod_unique_id was erroneously generating a second unique id when
7524 an internal redirect occured. Such redirects occur, for example,
7525 when processing a DirectoryIndex match. [Dean Gaudet]
7527 *) API: table_add, table_merge, and table_set include implicit pstrdup()
7528 of the key and value. But in many cases this is not required
7529 because the key/value is a constant, or the value has been built
7530 by pstrcat() or other similar means. New routines table_addn,
7531 table_mergen, and table_setn have been added to the API, these
7532 routines do not pstrdup() their arguments. The core code and
7533 standard modules were changed to take advantage of these routines.
7534 The resulting server is up to 20% faster in some situations.
7536 Note that it is easy to get code subtly wrong if you pass a key/value
7537 which is in a pool other than the pool of the table. The only
7538 safe thing to do is to pass key/values which are in the pool of
7539 the table, or in one of the ancestors of the pool of the table.
7540 i.e. if the table is part of a subrequest, a value from the main
7541 request's pool is OK since the subrequest pool is a sub_pool of the
7542 main request's pool (and therefore has a lifespan at most as long as
7543 the main pool). There is debugging code which can detect improper
7544 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
7545 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
7547 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
7548 which don't exist on disk more gracefully; handles vhosts properly.
7549 Update documentation to reflect the code -- if there's no
7550 MimeMagicFile directive then the module is not enabled.
7553 *) PORT: Some older *nix dialects cannot automatically start scripts
7554 which begin with a #! interpreter line (the shell starts the scripts
7555 appropriately on these platforms). Apache now supports starting of
7556 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
7557 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
7560 *) API: "typedef array_header table" removed from alloc.h, folks should
7561 have been writing to use table as if it were an opaque type, but even
7562 some standard modules got this wrong. By changing the definition
7563 to "typedef struct table table" module authors will receive compile
7564 time warnings that they're doing the wrong thing. This change
7565 facilitates future changes with more sophisticated table
7566 structures. Specifically, module authors should be using table_elts()
7567 to get access to an array_header * for the table. [Dean Gaudet]
7569 *) API: Renamed new_connection() to avoid namespace collision with LDAP
7570 library routines. [Ken Coar, Rasmus Lerdorf]
7572 *) WIN32: mod_speling is now available on the Win32 platform.
7575 *) For clarity the following compile time definition was changed:
7577 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
7579 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
7580 and not be a general notice that the OS has mmap(). Now the
7581 HAVE_MMAP/SHMGET #defines strictly are informational that the
7582 OS has that method of shared memory; the type to use for
7583 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
7584 and USE_SHMGET_SCOREBOARD). This allows outside modules to
7585 determine if shared memory is available and allows Apache
7586 to determine the best method to use for the scoreboard.
7589 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
7590 as do various earlier versions. It should be safe on all versions.
7591 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
7592 the slack code. A few other cleanups for Unixware.

7615 The choice of flock vs. fcntl was made based on timings which showed that
7616 even on non-NFS, non-exported filesystems fcntl() was an order of
7617 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
7618 that single socket users will see no difference. [Dean Gaudet] PR#467

7678 *) For maximum portability, the environment passed to CGIs should
7679 only contain variables whose names match the regex

7681 underscores over any character outside the regex. This
7682 affects HTTP_* variables, in a way that should be backward
7683 compatible for all the standard headers; and affects variables

7783 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller

7927 is the same for both per-server and per-directory context with only a
7928 minimum difference (the prefix stripping in per-dir context). As a
7929 side-effect some subtle restrictions and two recently discovered problems

8068 *) PORT: All SVR4 systems now use NET_SIZE_T = size_t, and
8069 use USE_SHMGET_SCOREBOARD.
8072 *) Various improvements in detecting config file errors (missing closing
8073 directives for <Directory>, <Files> etc. blocks, prohibiting global
8074 server settings in <VirtualHost> blocks, flagging unhandled multiple
8075 arguments to <Directory>, <Files> etc.)

8079 variable to provide this one to suexec'd CGIs, too.
8080 [M.D.Parker <mdpc@netcom.com>] PR#1284
8082 *) New support tool: src/support/split-logfile, a sample Perl script which
8083 splits up a combined access log into separate files based on the
8084 name of the virtual host (listed first in the log records by "%v").
8087 Changes with Apache 1.3b2 (there is no 1.3b1)
8089 *) TestCompile was not passing $LIBS [Dean Gaudet]
8091 *) Makefile.tmpl was not using $CFLAGS in the link phase.
8094 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
8095 rudimentary memory debugger which can be used on live servers with
8096 low impact -- it sets all allocated and freed memory bytes to 0xa5.
8097 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
8098 and free() for each object. This is far more expensive and should
8099 only be used for testing with tools such as Electric Fence and
8100 Purify. See main/alloc.c for more details. [Dean Gaudet]
8102 *) Configure uses a sh trap and didn't set its exitcode properly.
8103 [Dean Gaudet] PR#1159
8105 *) Yet another vhost revamp. Add the NameVirtualHost directive which
8106 explicitly lists the ip:port pairs that are to be used for name-vhosts.
8107 From a given ip:port, regardless what the Host: header is, you can
8108 only reach the vhosts defined on that ip:port. The precedence of
8109 vhosts was reversed to match other precedences in the config --
8110 the earlier vhosts override the later vhosts. All vhost matching was
8111 moved into http_vhost.[ch]. [Dean Gaudet]
8113 *) ap_inline can be used to force inlining. GNUC __attribute__() can
8114 be used for whatever reason is appropriate (i.e. format() warnings
8115 for printf style functions). Both are enabled only with
8116 gcc >= 2.7.x (so that we have fewer support issues with older
8117 versions). [Dean Gaudet]
8119 *) Fix support for Proxy Authentication (we were testing the response
8120 status too early). [Marc Slemko]
8122 *) CoreDumpDirectory directive directs where the core file is
8123 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
8124 received. [Marc Slemko, Dean Gaudet]
8126 *) PORT: Support for Atari MINT.
8127 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
8129 *) When booting, apache will now detach itself from stdin, stdout,
8130 and stderr. stderr will not be detached until after the config
8131 files have been read so you will be able to see initial error
8132 messages. After that all errors are logged in the error_log.
8133 This makes it more convenient to start apache via rsh, ssh,
8134 or crontabs. [Dean Gaudet] PR#523
8136 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
8137 Also removed the auto-generated link to www.apache.org that was the
8138 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
8140 *) send_fb would not detect aborted connections in some situations.
8143 *) mod_include would use uninitialized data when parsing certain
8144 expressions involving && and ||. [Brian Slesinsky] PR#1139
8146 *) mod_imap should only handle GET methods. [Jay Bloodworth]
8148 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
8150 *) mod_autoindex improperly counted &escapes; as more than one
8151 character in the description. It also improperly truncated
8152 descriptions that were exactly the maximum length.
8155 *) RedirectMatch was not properly escaping the result (PR#1155). Also
8156 "RedirectMatch /advertiser/(.*) $1" is now permitted.
8159 *) mod_include now uses symbolic names to check for request success
8160 and return HTTP errors, and correctly handles all types of
8161 redirections (previously it only did temporary redirect correctly).
8162 [Ken Coar, Roy Fielding]
8164 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
8165 r->filename. Since those two are meant to be in sync with each other
8166 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
8168 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
8169 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]
8171 *) Inetd mode (which is buggy) uses timeouts without having setup the
8172 jmpbuffer. [Dean Gaudet] PR#1064
8174 *) Work around problem under Linux where a child will start looping
8175 reporting a select error over and over.
8176 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
8178 *) Fixed error in proxy_util.c when looping through multiple host IP
8179 addresses. [Lars Eilebrecht] PR#974
8181 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
8182 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
8183 bytes before writing, but it will never split a log entry across a
8184 buffer boundary. [Dean Gaudet]
8186 *) API: the short_score record has been split into two pieces, one which
8187 the parent writes on, and one which the child writes on. As part of
8188 this change the get_scoreboard_info() function was removed, and
8189 scoreboard_image was exported. This change fixes a race condition
8190 in file based scoreboard systems, and speeds up changes involving the
8191 scoreboard in earlier 1.3 development. [Dean Gaudet]
8193 *) API: New register_other_child() API (see http_main.h) which allows
8194 modules to register children with the parent for maintenance. It
8195 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
8197 *) API: New piped_log API (see http_log.h) which implements piped logs,
8198 and will use register_other_child to implement reliable piped logs
8199 when it is available. The reliable piped logs part can be disabled
8200 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
8201 logs is only available on Unix. [Dean Gaudet]
8203 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
8204 meets_conditions(). This allows conditional HTTP selection to be
8205 handled separately from the storing of the header fields, and provides
8206 the ability for CGIs to set their own ETags for conditional checking.
8207 [Ken Coar, Roy Fielding] PR#895
8209 *) Changes to mod_log_config to allow naming of format strings.
8210 Format nicknames are defined with "LogFormat fmt nickname", and can
8211 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
8214 *) New module, "mod_speling", which can help find files even when
8215 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
8217 *) API: New function child_terminate() triggers the child process to
8218 exit, while allowing the child finish what it needs to for the
8219 current request first.
8220 [Doug MacEachern, Alexei Kosut]
8222 *) Windows now defaults to using full status reports with mod_status.
8223 [Alexei Kosut] PR #1094
8225 *) *Really* disable all mod_rewrite operations if the engine is off.
8226 Some things (like RewriteMaps) were checked/performed even if they
8227 weren't supposed to be. [Ken Coar] PR #991
8229 *) Implement a new timer scheme which eliminates the need to call alarm() all
8230 the time. Instead a counter in the scoreboard for each child is used to
8231 show when the child has made forward progress. The parent samples this
8232 counter every scoreboard maintenance cycle, and issues SIGALRM if no
8233 progress has been made in the timeout period. This reduces the static
8234 request best-case syscall count to 22 from 29. This scheme is only
8235 used by systems with memory-based scoreboards. [Dean Gaudet]
8237 *) The proxy now properly handles CONNECT requests which are sent
8238 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
8240 *) A script called apachectl has been added to the support
8241 directory. This script allows you to do things such as
8242 "apachectl start" and "apachectl restart" from the command
8245 *) Modules and core routines are now put into libraries, which
8246 simplifies the link line tremendously (among other advantages).
8249 *) Some of the MD5 names defined in Apache have been renamed to have
8250 an `ap_' prefix to avoid conflicts with routines supplied by
8251 external libraries. [Ken Coar]
8253 *) Removal of mod_auth_msql.c from the distribution. There are many
8254 other options for databases today. Rather than offer one option,
8255 offer none at this time. mod_auth_msql and other SQL database
8256 authentication modules can be found at the Apache Module Registry.
8257 http://modules.apache.org/ It would be nice to offer a generic
8258 mod_auth_sql option in the near future.
8260 *) PORT: BeOS support added [Alexei Kosut]
8262 *) Configure no longer accepts the -make option, since it creates
8263 Makefile on the fly based on Makefile.tmpl and Configuration.
8265 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
8266 of forcibly killing off all its processes and exiting without
8267 cleaning up. [Alexei Kosut]
8269 *) API: A new field in the request_rec, r->mtime, has been added to
8270 avoid gratuitous parsing of date strings. It is intended to hold
8271 the last-modified date of the resource (if applicable). An
8272 update_mtime() routine has also been added to advance it if
8273 appropriate. [Roy Fielding, Ken Coar]
8275 *) SECURITY: If a htaccess file can not be read due to bad permissions,
8276 deny access to the directory with a HTTP_FORBIDDEN. The previous
8277 behavior was to ignore the htaccess file if it could not be read.
8278 This change may make some setups with unreadable htaccess files
8279 stop working. [Marc Slemko] PR#817
8281 *) Add aplog_error() providing a mechanism to define levels of
8282 verbosity to the server error logging. This addition also provides
8283 the ability to log errors using syslogd. Error logging is configurable
8284 on a per-server basis using the LogLevel directive. Conversion
8285 of log_*() in progress. [Randy Terbush]
8287 *) Further enhance aplog_error() to not log filename, line number, and
8288 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
8290 *) WIN32: Canonicalise filenames under Win32. Short filenames are
8291 converted to long ones. Backslashes are converted to forward
8292 slashes. Case is converted to lower. Parts of URLs that do not
8293 correspond to files are left completely alone. [Ben Laurie]
8295 *) PORT: 2 new OSs added to the list of ports:
8296 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
8297 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
8299 *) Add the server version (SERVER_VERSION macro) to the "server
8300 configured and running" entry in the error_log. Also build an
8301 object file at link-time that contains the current time
8302 (SERVER_BUILT global const char[]), and include that in the
8305 *) Set r->headers_out when sending responses from the proxy.
8306 This fixes things such as the logging of headers sent from
8307 the proxy. [Marc Slemko] PR#659
8309 *) support/httpd_monitor is no longer distributed because the
8310 scoreboard should not be file based if at all possible. Use
8311 mod_status to see current server snapshot.
8313 *) (set_file_slot): New function, allowing auth directives to be
8314 independent of the server root, so the server documents can be
8315 moved to a different directory or machine more easily.
8316 [David J. MacKenzie]
8318 *) If no TransferLog is given explicitly, decline
8319 to log. This supports coexistence with other logging modules,
8320 such as the custom one that UUNET uses. [David J. MacKenzie]
8322 *) Check for titles in server-parsed HTML files.
8323 Ignore leading newlines and returns in titles. The old behavior
8324 of replacing a newline after <title> with a space causes the
8325 title to be misaligned in the listing. [David J. MacKenzie]
8327 *) Change mod_cern_meta to be configurable on a per-directory basis.
8328 [David J. MacKenzie]
8330 *) Add 'Include' directive to allow inclusion of configuration
8331 files within configuration files. [Randy Terbush]
8333 *) Proxy errors on connect() are logged to the error_log (nothing
8334 new); now they include the IP address and port that failed
8335 (*that's* new). [Ken Coar, Marc Slemko] PR#352
8337 *) Various architectures now define USE_MMAP_FILES which causes
8338 the server to use mmap() for static files. There are two
8339 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
8340 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
8341 number of bytes written in one cycle from a single mmap()d object,
8342 default 32768). [Dean Gaudet]
8344 *) API: Added post_read_request API phase which is run right after reading
8345 the request from a client, or right after an internal redirect. It is
8346 useful for modules setting environment variables that depend only on
8347 the headers/contents of the request. It does not run during subrequests
8348 because subrequests inherit pretty much everything from the main
8349 request. [Dean Gaudet]
8351 *) Added mod_unique_id which is used to generate a unique identifier for
8352 each hit, available in the environment variable UNIQUE_ID.
8355 *) init_modules is now called after the error logs have been opened. This
8356 allows modules to emit information messages into the error logs.
8359 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
8360 information for case where proxy module is not available. [Marc Slemko]
8362 *) PORT: Apache has need for mutexes to serialize its children around
8363 accept. In prior versions either fcntl file locking or flock file
8364 locking were used. The method is chosen by the definition of
8365 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
8366 and FLOCK for flock(). New options have been added:
8367 - SYSVSEM to use System V style semaphores
8368 - PTHREAD to use POSIX threads (appears to work on Solaris only)
8369 - USLOCK to use IRIX uslock
8370 Based on timing various techniques, the following changes were made
8372 - Linux 2.x uses flock instead of fcntl
8373 - Solaris 2.x uses pthreads
8374 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
8375 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
8376 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
8377 Martijn Koster <m.koster@pobox.com>]
8379 *) PORT: The semantics of accept/select make it very desirable to use
8380 mutexes to serialize accept when multiple Listens are in use. But
8381 in the case where only a single socket is open it is sometimes
8382 redundant to serialize accept(). Not all unixes do a good job with
8383 potentially dozens of children blocked on accept() on the same
8384 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
8385 the server will avoid serialization when listening on only one socket,
8386 and use serialization when listening on multiple sockets.
8387 [Dean Gaudet] PR#467
8389 *) Configure changes: TestLib replaced by TestCompile, which has
8390 some additional capability (such as doing a sanity check of
8391 the compiler and flags selected); the version of Solaris is now
8392 available via the #define value of SOLARIS2; IRIX n32bit libs
8393 now supported and selectable by new Configuration Rule: IRIXN32;
8394 We no longer default to -O2 optimization. [Jim Jagielski]
8396 *) Updated Configure: Configuration now uses AddModule to specify
8397 module source or binary file location, relative to src directory.
8398 Modules can be dropped into modules/extra, or in their own
8399 directory, and modules can come with a Makefile or Configure can
8400 create one. Modules can add compiler or library information to
8401 generated Makefiles. [Paul Sutton]
8403 *) Source core re-organisation: distributed modules are now in
8404 modules/standard. All other source code is in main. OS-specific
8405 code is in os/{unix,emx,win32} directories. [Paul Sutton]
8407 *) mod_browser has been removed, since it's replaced by mod_setenvif.
8410 *) Fix another long-standing bug in sub_req_lookup_file where it would
8411 happily skip past access checks on subdirectories looked up with
8412 relative paths. (It's used by mod_dir, mod_negotiation,
8413 and mod_include.) [Dean Gaudet]
8415 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
8416 N is the number of <Directory> sections, and M is the number of
8417 components in the filename of an object.
8419 To achieve this optimization the following config changes were made:
8420 - Wildcards (* and ?, not the regex forms) in <Directory>s,
8421 <Files>s, and <Location>s now treat a slash as a special
8422 character. For example "/home/*/public_html" previously would
8423 match "/home/a/andrew/public_html", now it only matches things
8424 like "/home/bob/public_html". This mimics /bin/sh behaviour.
8425 - It's possible now to use [] wildcarding in <Directory>, <Files>
8427 - Regex <Directory>s are applied after all non-regex <Directory>s.
8431 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
8432 and corrupted paths. [Dean Gaudet]
8434 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
8435 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
8436 be accessed now via backreferences $1..$9 in RewriteConds test-against
8437 strings in addition to RewriteRules subst string. Second the grouped
8438 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
8439 via backreferences %1..%9 both in following RewriteCond test-against
8440 strings and RewriteRules subst string. This provides maximum flexibility
8441 through the use of backreferences.
8442 Additionally the rewriting engine was cleaned up by putting common
8443 code to the new expand_backrefs_inbuffer() function.
8444 [Ralf S. Engelschall]
8446 *) When merging the main server's <Directory> and <Location> sections into
8447 a vhost, put the main server's first and the vhost's second. Otherwise
8448 the vhost can't override the main server. [Dean Gaudet] PR#717
8450 *) The <Directory> code would merge and re-merge the same section after
8451 a match was found, possibly causing problems with some modules.
8454 *) ip-based vhosts are stored and queried using a hashing function, which
8455 has been shown to improve performance on servers with many ip-vhosts.
8456 Some other changes had to be made to accommodate this:
8457 - the * address for vhosts now behaves like _default_
8458 - the matching process now is:
8459 - match an ip-vhost directly via hash (possibly matches main
8461 - if that fails, just pretend it matched the main server
8462 - if so far only the main server has been matched, perform
8463 name-based lookups (ServerName, ServerAlias, ServerPath)
8464 *only on name-based vhosts*
8465 - if they fail, look for _default_ vhosts
8466 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
8468 *) dbmmanage overhaul:
8469 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
8470 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
8471 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
8472 - provide better seed for rand
8473 - prompt for password as per getpass(3) (turn off echo, read from
8475 - use "newstyle" crypt based on $Config{osname} ($^O)
8476 - will not add a user if already in database, use new `update' command
8478 - added `check' command to check a users' password
8479 - added `import' command to convert existing password text-files or
8480 dbm files exported with `view'
8481 - more descriptive usage, general cleanup, 'use strict' clean, etc.
8484 *) Added psocket() which is a pool form of socket(), various places within
8485 the proxy weren't properly blocking alarms while registering the cleanup
8486 for its sockets. bclose() now uses pclose() and pclosesocket(). There
8487 was a bug where the client socket was being close()d twice due a still
8488 registered cleanup. [Dean Gaudet]
8490 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
8493 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
8494 [Jason Venner <jason@idiom.com>] PR#667
8496 *) Enable ``=""'' for RewriteCond directives to match against
8497 the empty string. This is the preferred way instead of ``^$''.
8498 [Ralf S. Engelschall]
8500 *) Fixed an infinite loop in mod_imap for references above the server root
8501 [Dean Gaudet] PR#748
8503 *) mod_proxy now has a ReceiveBufferSize directive, similar to
8504 SendBufferSize, so that the TCP window can be set appropriately
8505 for LFNs. [Phillip A. Prindeville]
8507 *) mod_browser has been replaced by the more general mod_setenvif
8508 (courtesy of Paul Sutton). BrowserMatch* directives are still
8509 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
8510 UnSetEnvIfZero directives. [Ken Coar]
8512 *) "HostnameLookups double" forces double-reverse DNS to succeed in
8513 order for remote_host to be set (for logging, or for the env var
8514 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
8517 *) mod_access overhaul:
8518 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
8519 and cidr syntax (i.e. 10.1.0.0/16). PR#762
8520 - Critical path was sped up by pre-computing a few things at config time.
8521 - The undocumented syntax "allow user-agents" was removed,
8522 the replacement is "allow from env=foobar" combined with mod_browser.
8523 - When used with hostnames it now forces a double-reverse lookup
8524 no matter what the directory settings are. This double-reverse
8525 doesn't affect any of the other routines that use the remote
8526 hostname. In particular it's still passed to CGIs and the log
8527 without the double-reverse check. Related PR#860.
8530 *) When a large bwrite() occurs (larger than the internal buffer size),
8531 while there is already something in the buffer, apache will combine
8532 the large write and the buffer into a single writev(). (This is
8533 in anticipation of using mmap() for reading files.)
8536 *) In obscure cases where a partial socket write occurred while chunking,
8537 Apache would omit the chunk header/footer on the next block. Cleaned
8538 up other bugs/inconsistencies in error conditions in buff.c. Fixed
8539 a bug where a long pause in DNS lookups could cause the last packet
8540 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
8542 *) API: Added child_exit function to module structure. This is called
8543 once per "heavy-weight process" just before a server child exit()'s
8544 e.g. when max_requests_per_child is reached, etc.
8545 [Doug MacEachern, Dean Gaudet]
8547 *) mod_include cleanup showed that handle_else was being used to handle
8548 endif. It didn't cause problems, but it was cleaned up too.
8551 *) mod_cern_meta would attempt to find meta files for the directory itself
8552 in some cases, but not in others. It now avoids it in all cases.
8555 *) mod_mime_magic would core dump if there was a decompression error.
8556 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
8558 *) PORT: some variants of DGUX require -lsocket -lnsl
8559 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
8561 *) mod_autoindex now allows sorting of FancyIndexed directory listings
8562 by the various fields (name, size, et cetera), either in ascending
8563 or descending order. Just click on the column header. [Ken Coar]
8565 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
8566 CPUs like the Alpha. Apache still stores ints in pointers, but that's
8567 the relatively safe direction. [Dean Gaudet] PR#344
8569 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
8570 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
8572 *) child_main avoids an unneeded call to select() when there is only one
8573 listening socket. [Dean Gaudet]
8575 *) In the event that the server is starved for idle servers it will
8576 spawn 1, then 2, then 4, ..., then 32 servers each second,
8577 doubling each second. It'll also give a warning in the errorlog
8578 since the most common reason for this is a poor StartServers
8579 setting. The define MAX_SPAWN_RATE can be used to raise/lower
8580 the maximum. [Dean Gaudet]
8582 *) Apache now provides an effectively unbuffered connection for
8583 CGI scripts. This means that data will be sent to the client
8584 as soon as the CGI pauses or stops output; previously, Apache would
8585 buffer the output up to a fixed buffer size before sending, which
8586 could result in the user viewing an empty page until the CGI finished
8587 or output a complete buffer. It is no longer necessary to use an
8588 "nph-" CGI to get unbuffered output. Given that most CGIs are written
8589 in a language that by default does buffering (e.g. perl) this
8590 shouldn't have a detrimental effect on performance.
8592 "nph-" CGIs, which formerly provided a direct socket to the client
8593 without any server post-processing, were not fully compatible with
8594 HTTP/1.1 or SSL support. As such they would have had to implement
8595 the transport details, such as encryption or chunking, in order
8596 to work properly in certain situations. Now, the only difference
8597 between nph and non-nph scripts is "non-parsed headers".
8598 [Dean Gaudet, Sameer Parekh, Roy Fielding]
8600 *) If a BUFF is switched from buffered to unbuffered reading the first
8601 bread() will return whatever remained in the buffer prior to the
8602 switch. [Dean Gaudet]
8604 Changes with Apache 1.3a1
8606 *) Added another Configure helper script: TestLib. It determines
8607 if a specified library exists. [Jim Jagielski]
8609 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
8610 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
8613 *) PORT: Some architectures use size_t for various lengths in network
8614 functions such as accept(), and getsockname(). The definition
8615 NET_SIZE_T is used to control this. [Dean Gaudet]
8617 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
8618 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
8619 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
8621 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
8622 [Igor N Kovalenko <infoh@mail.wplus.net>]
8624 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
8625 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
8626 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
8627 [Dean Gaudet] related PR#875
8629 *) API: Correct child_init() slot declaration from int to void, to
8630 match the init() declaration. Update mod_example to use the new
8633 *) added transport handle slot (t_handle) to the BUFF structure
8636 *) get_client_block() returns wrong length if policy is
8637 REQUEST_CHUNKED_DECHUNK.

8647 *) AddModuleInfo directive for mod_info which allows you to annotate
8648 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
8650 *) Added NoProxy directive to avoid using ProxyRemote for selected
8651 addresses. Added ProxyDomain directive to cause unqualified
8652 names to be qualified by redirection.
8653 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
8655 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
8656 header to the remote host in the proxy. [Sameer Parekh and
8659 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
8660 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
8661 URLs, fixed rewritelog(), fixed forced response code handling on
8662 redirects from within .htaccess files, disabled pipe locking under
8663 braindead SunOS 4.1.x, allow env variables to be set even on rules with
8664 no substitution, bugfixed situations where HostnameLookups is off, made
8665 mod_rewrite more thread-safe for NT port and fixed problem when creating
8666 an empty query string via "xxx?".
8667 This update also removes the copyright of Ralf S. Engelschall,
8668 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
8669 exclusively copyrighted by the Apache Group now. This happened because
8670 the author now has gifted mod_rewrite exclusively to the Apache Group and
8671 no longer maintains an external version.
8672 [Ralf S. Engelschall]
8674 *) API: Added child_init function to module structure. This is called
8675 once per "heavy-weight process" before any requests are handled.
8676 See http_config.h for more details. [Dean Gaudet]
8678 *) Anonymous_LogEmail was logging on each subrequest.
8679 [Dean Gaudet] PR#421, 868
8681 *) API: Added is_initial_req() which tests if the request being
8682 processed is the initial request, or a subrequest.
8685 *) Extended SSI (mod_include) now handles additional relops for
8686 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
8688 *) Configure fixed to correctly propagate user-selected options and
8689 settings (such as CC and OPTIM) to Makefiles other than
8690 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
8692 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
8693 directory indices to start with the contents of the HeaderName file
8694 if there is one. If there isn't one, the behaviour is unchanged.
8695 [Ken Coar, Roy Fielding, Andrey A. Chernov]
8697 *) WIN32: Modules can now be dynamically loaded DLLs using the
8698 LoadModule/LoadFile directives. Note that module DLLs must be
8699 compiled with the multithreaded DLL version of the runtime library.
8700 [Alexei Kosut and Ben Laurie]
8702 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
8703 This allows the admin to completely remove automatic indexing
8704 from the server, while still supporting the basic functions of
8705 trailing-slash redirects and DirectoryIndex files. Note that if
8706 you're carrying over an old Configuration file and you use directory
8707 indexing then you'll want to add:
8709 Module autoindex_module mod_autoindex.o
8711 before mod_dir in your Configuration. [Dean Gaudet]
8713 *) popendir/pclosedir created to properly protect directory scanning.
8714 [Dean Gaudet] PR#525
8716 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
8717 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
8718 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
8721 *) The AccessFileName directive can now take more than one filename.
8722 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
8724 *) The new mod_mime_magic can be used to "magically" determine the type
8725 of a file if the extension is unknown. Based on the unix file(1)
8726 command. [Ian Kluft <ikluft@cisco.com>]
8728 *) We now determine and display the time spent processing a
8729 request if desired. [Jim Jagielski]
8731 *) mod_status: PID field of "dead" child slots no longer displays
8732 main httpd process's PID. [Jim Jagielski]
8734 *) Makefile.nt added - to build all the bits from the command line:
8735 nmake -f Makefile.nt
8736 Doesn't yet work properly. [Ben Laurie]
8738 *) Default text of 404 error is now "Not Found" rather than the
8739 potentially misleading "File Not Found". [Ken Coar]
8741 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
8742 for the net if we require people that actually need this data to
8743 enable it. [Linus Torvalds]
8745 *) directory_walk() is an expensive function, keep a little more state to
8746 avoid needless string counting. Add two new functions make_dirstr_parent
8747 and make_dirstr_prefix which replace all existing uses of make_dirstr.
8748 The new functions are a little less general than make_dirstr, but
8749 work more efficiently (less memory, less string counting).
8752 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
8753 to LDFLAGS) to avoid complications with lex rules in make files.
8754 [Dean Gaudet] PR#372
8756 *) run_method optimized to avoid needless scanning over NULLs in the
8757 module list. [Dean Gaudet]
8759 *) Revamp of (unix) scoreboard management code such that it avoids
8760 unnecessary traversals of the scoreboard on each hit. This is
8761 particularly important for high volume sites with a large
8762 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
8763 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
8764 httpd.h. [Dean Gaudet]
8766 *) In configurations using multiple Listen statements it was possible for
8767 busy sockets to starve other sockets of service. [Dean Gaudet]
8769 *) Added hook so standalone_main can be replaced at compile time
8770 (define STANDALONE_MAIN)
8773 *) Lowest-level read/write functions in buff.c will be replaced with
8774 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
8775 compile time. The default sfio discipline will behave as apache
8776 would without sfio compiled in.
8779 *) Enhance UserDir directive (mod_userdir) to accept a list of
8780 usernames for the 'disable' keyword, and add 'enable user...' to
8781 selectively *en*able userdirs if they're globally disabled.
8784 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
8785 will work with Netscape dbm files. (dbmmanage will probably not
8786 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
8788 *) Add a ListenBacklog directive to control the backlog parameter
8789 passed to listen(). Also change the default to 511 from 512.
8792 *) API: A new handler response DONE which informs apache that the
8793 request has been handled and it can finish off quickly, similar to
8794 how it handles errors. [Rob Hartill]
8796 *) Turn off chunked encoding after sending terminating chunk/footer
8797 so that we can't do it twice by accident. [Roy Fielding]
8799 *) mod_expire also issues Cache-Control: max-age headers.
8802 *) API: Added kill_only_once option for free_proc_chain so that it won't
8803 aggressively try to kill off specific children. For fastcgi.
8804 [Stanley Gambarin <gambarin@OpenMarket.com>]
8806 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
8808 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
8809 When used together, these cause mod_dir to emit HEIGHT and WIDTH
8810 attributes in the FancyIndexing IMG tags. [Ken Coar]
8812 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
8814 *) PORT: Added Windows NT support
8815 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
8817 Changes with Apache 1.2.6
8819 *) mod_include when using XBitHack Full would send ETags in addition to
8820 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
8821 [Dean Gaudet] PR#1133
8823 *) SECURITY: When a client connects to a particular port/addr, and
8824 gives a Host: header ensure that the virtual host requested can
8825 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
8827 *) Support virtual hosts with wildcard port and/or multiple ports
8828 properly. [Ed Korthof <ed@organic.com>]
8830 *) Fixed some case-sensitivity issues according to RFC2068.
8833 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
8834 and mod_include.c. [Dean Gaudet]
8836 *) Variable 'cwd' was being used pointlessly before being set.
8839 *) SIGURG doesn't exist on all platforms.
8840 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
8842 *) When an error occurs during a POST, or other operation with a
8843 request body, the body has to be read from the net before allowing
8844 a keepalive session to continue. [Roy Fielding] PR#1399
8846 *) When an error occurs in fcntl() locking suggest the user look up
8847 the docs for LockFile. [Dean Gaudet]
8849 *) table_set() and table_unset() did not deal correctly with
8850 multiple occurrences of the same key. [Stephen Scheck
8851 <sscheck@infonex.net>, Ben Laurie] PR#1604
8853 *) send_fd_length() did not calculate total_bytes_sent properly in error
8854 cases. [Ben Reser <breser@regnow.com>] PR#1366
8856 *) r->connection->user was allocated in the wrong pool causing corruption
8857 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
8859 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
8860 Also removed the auto-generated link to www.apache.org that was the
8861 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
8863 *) Multiple "close" tokens may have been set in the "Connection"
8864 header, not an error, but a waste.
8865 [Ronald.Tschalaer@psi.ch] PR#1683
8867 *) "basic" and "digest" auth tokens should be tested case-insensitive.
8868 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
8870 *) It appears the "257th byte" bug (see
8871 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
8872 at the 256th byte as well. Fixed. [Dean Gaudet]
8874 *) mod_rewrite would not handle %3f properly in some situations.
8877 *) Apache could generate improperly chunked HTTP/1.1 responses when
8878 the bputc() or rputc() functions were used by modules (such as
8879 mod_include). [Dean Gaudet]
8881 *) #ifdef wrap a few #defines in httpd.h to make life easier on
8882 some ports. [Ralf Engelschall]
8884 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
8886 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
8888 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
8890 Changes with Apache 1.2.5
8892 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
8893 only an issue on systems without a MAXDNAME define or where
8894 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
8896 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
8899 *) Fix core dump in the ftp proxy when reading incorrectly formatted
8900 directory listings. [Marc Slemko]
8902 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
8905 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
8906 is used to read various types of files such as htaccess and
8907 htpasswd files. [Marc Slemko]
8909 *) SECURITY: Ensure that the buffer returned by ht_time is always
8910 properly null terminated. [Marc Slemko]
8912 *) SECURITY: General mod_include cleanup, including fixing several
8913 possible buffer overflows and a possible infinite loop. This cleanup
8914 was done against 1.3 code and then backported to 1.2, the result
8915 is a large difference (due to indentation cleanup in 1.3 code).
8916 Users interested in seeing a smaller set of relevant differences
8917 should consider comparing against src/modules/standard/mod_include.c
8918 from the 1.3b3 release. Non-indentation changes to mod_include
8919 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
8921 *) SECURITY: Numerous changes to mod_imap in a general cleanup
8922 including fixing a possible buffer overflow. This cleanup also
8923 was done with 1.3 code as a basis, see the the previous note
8924 about mod_include. [Dean Gaudet]
8926 *) SECURITY: If a htaccess file can not be read due to bad
8927 permissions, deny access to the directory with a HTTP_FORBIDDEN.
8928 The previous behavior was to ignore the htaccess file if it could not
8929 be read. This change may make some setups with unreadable
8930 htaccess files stop working. PR#817 [Marc Slemko]
8932 *) SECURITY: no2slash() was O(n^2) in the length of the input.
8933 Make it O(n). This inefficiency could be used to mount a denial
8934 of service attack against the Apache server. Thanks to
8935 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting

8957 reporting a select error over and over.
8958 [Rick Franchuk <rickf@transpect.net>] PR#1107
8960 Changes with Apache 1.2.4
8962 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
8963 always making requests with the full-URI instead of just the URI path.
8964 [Marc Slemko, Roy Fielding]
8966 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
8967 on this platform. [Marc Slemko]
8969 Changes with Apache 1.2.3
8971 *) The request to a remote proxy was mangled if it was generated as the
8972 result of a ProxyPass directive. URL schemes other than http:// were not
8973 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,

8976 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
8977 information for case where proxy module is not available. [Marc Slemko]
8979 *) Force proxy to always respond as HTTP/1.0, which it was failing to
8980 do for errors and cached responses. [Roy Fielding]
8982 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
8984 Changes with Apache 1.2.2 [not released]
8986 *) Fixed another long-standing bug in sub_req_lookup_file where it would
8987 happily skip past access checks on subdirectories looked up with relative
8988 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
8991 *) Add lockfile name to error message printed out when
8992 USE_FLOCK_SERIALIZED_ACCEPT is defined.
8995 *) Enhanced the chunking and error handling inside the buffer functions.
8996 [Dean Gaudet, Roy Fielding]
8998 *) When merging the main server's <Directory> and <Location> sections into
8999 a vhost, put the main server's first and the vhost's second. Otherwise
9000 the vhost can't override the main server. [Dean Gaudet] PR#717
9002 *) The <Directory> code would merge and re-merge the same section after
9003 a match was found, possibly causing problems with some modules.
9006 *) Fixed an infinite loop in mod_imap for references above the server root.
9007 [Dean Gaudet] PR#748
9009 *) mod_include cleanup showed that handle_else was being used to handle
9010 endif. It didn't cause problems, but it was cleaned up too.
9013 *) Last official synchronization of mod_rewrite with author version (because
9014 mod_rewrite is now directly developed by the author at the Apache Group):
9015 o added diff between mod_rewrite 3.0.6+ and 3.0.9
9016 minus WIN32/NT stuff, but plus copyright removement.
9018 - workaround for detecting infinite rewriting loops
9019 - fixed setting of env vars when "-" is used as subst string
9020 - fixed forced response code on redirects (PR#777)
9021 - fixed cases where r->args is ""
9022 - kludge to disable locking on pipes under braindead SunOS
9023 - fix for rewritelog in cases where remote hostname is unknown
9024 - fixed totally damaged request_rec walk-back loop
9025 o remove static from local data and add static to global ones.
9026 o replaced ugly proxy finding stuff by simple
9027 find_linked_module("mod_proxy") call.
9028 o added missing negation char on rewritelog()
9029 o fixed a few comment typos

9035 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to

9060 *) API: In HTTP/1.1, whether or not a request message contains a body
9061 is independent of the request method and based solely on the presence
9062 of a Content-Length or Transfer-Encoding. Therefore, our default
9063 handlers need to be prepared to read a body even if they don't know
9064 what to do with it; otherwise, the body would be mistaken for the
9065 next request on a persistent connection. discard_request_body()
9066 has been added to take care of that. [Roy Fielding] PR#378

9078 or named sockets to invoke programs for an extremely crude form of
9081 *) SECURITY: HeaderName and ReadmeName were settable in .htaccess and
9082 could contain "../" allowing a local user to "publish" any file on
9083 the system. No slashes are allowed now. [Dean Gaudet]
9085 *) SECURITY: It was possible to violate the symlink Options using mod_dir
9086 (headers, readmes, titles), mod_negotiation (type maps), or
9087 mod_cern_meta (meta files). [Dean Gaudet]
9089 *) SECURITY: Apache will refuse to run as "User root" unless
9090 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
9092 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
9093 if it contained a .htaccess disallowing symlinks. This is contrary
9094 to the rule that symlink permissions are tested with the symlink
9095 options of the parent directory. [Dean Gaudet] PR#353
9097 *) CONFIG: The LockFile directive can be used to place the serializing
9098 lockfile in any location. It previously defaulted to /usr/tmp/htlock.

9102 *) Request processing now retains state of whether or not the request
9103 body has been read, so that internal redirects and subrequests will
9104 not try to read it twice (and block). [Roy Fielding]
9106 *) Add a placeholder in modules/Makefile to avoid errors with certain

9109 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.

9112 *) mod_include was not properly changing the current directory.
9113 [Marc Slemko] PR#742
9115 *) Attempt to work around problems with third party libraries that do not
9116 handle high numbered descriptors (examples include bind, and
9117 solaris libc). On all systems apache attempts to keep all permanent
9118 descriptors above 15 (called the low slack line). Solaris users
9119 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
9120 which keeps all non-FILE * descriptors above 255. On all systems
9121 this should make supporting large numbers of vhosts with many open
9122 log files more feasible. If this causes trouble please report it,
9123 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
9124 [Dean Gaudet] various PRs
9126 *) Related to the last entry, network sockets are now opened before
9127 log files are opened. The only known case where this can cause
9128 problems is under Solaris with many virtualhosts and many Listen
9129 directives. But using -DHIGH_SLACK_LINE=256 described above will
9130 work around this problem. [Dean Gaudet]
9132 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
9135 *) Improved unix error response logging. [Marc Slemko]

9138 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
9139 when a URL http://... was used in conjunction with a special
9140 redirect flag, e.g. R=permanent, the permanent status was lost.

9221 *) If a soft_timeout occurs after keepalive is set, then the main child
9222 loop would try to read another request even though the connection
9223 has been aborted. [Roy Fielding]
9225 *) Configure changes: Allow for whitespace at the start of a
9226 Module declaration. Also, be more understanding about the
9227 CC=/OPTIM= format in Configuration. Finally, fix compiler
9228 flags if using HP-UX's cc compiler. [Jim Jagielski]
9230 *) Subrequests and internal redirects now inherit the_request from the
9231 original request-line. [Roy Fielding]
9233 *) Test for error conditions before creating output header fields, since
9234 we don't want the error message to include those fields. Likewise,
9235 reset the content_language(s) and content_encoding of the response
9236 before generating or redirecting to an error message, since the new
9237 message will have its own Content-* definitions. [Dean Gaudet]
9239 *) Restored the semantics of headers_out (headers sent only with 200..299
9240 and 304 responses) and err_headers_out (headers sent with all responses).
9241 Avoid the overhead of copying tables if err_headers_out is empty
9242 (the usual case). [Roy Fielding]
9244 *) Fixed a couple places where a check for the default Content-Type was
9245 not properly checking both the value configured by the DefaultType
9246 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
9247 of DEFAULT_TYPE to match the documented default (text/plain).

9250 *) Escape the HTML-sensitive characters in the Request-URI that is
9251 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
9253 *) Properly initialize the flock structures used by the mutex locking
9254 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
9257 *) The method for determining PATH_INFO has been restored to the pre-1.2b
9258 (and NCSA httpd) definition wherein it was the extra path info beyond
9259 the CGI script filename. The environment variable FILEPATH_INFO has
9260 been removed, and instead we supply the original REQUEST_URI to any
9261 script that wants to be Apache-specific and needs the real URI path.
9262 This solves a problem with existing scripts that use extra path info
9263 in the ScriptAlias directive to pass options to the CGI script.
9266 *) The _default_ change in 1.2b10 will change the behaviour on configs
9267 that use multiple Listen statements for listening on multiple ports.
9268 But that change is necessary to make _default_ consistent with other
9269 forms of <VirtualHost>. It requires such configs to be modified
9270 to use <VirtualHost _default_:*>. The documentation has been
9271 updated. [Dean Gaudet] PR#530
9273 *) If an ErrorDocument CGI script is used to respond to an error
9274 generated by another CGI script which has already read the message
9275 body of the request, the server would block trying to read the
9276 message body again. [Rob Hartill]
9278 *) signal() replacement conflicted with a define on QNX (and potentially
9279 other platforms). Fixed. [Ben Laurie] PR#512
9281 Changes with Apache 1.2b10

9299 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
9300 changes and in anticipation of 1.2 final release. [Roy Fielding]
9302 *) Fix problem with scripts not receiving a SIGPIPE when client drops
9303 the connection (e.g., when user presses Stop). Apache will now stop
9304 trying to send a message body immediately after an error from write.
9305 [Roy Fielding and Nathan Kurz] PR#335
9307 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
9308 than mod_alias, and mod_alias has higher priority than mod_proxy;
9309 rearranged other modules to enhance understanding of their purpose
9310 and relative order (and maybe even reduce some overhead).
9311 [Roy Fielding and Sameer Parekh]
9313 *) Fix graceful restart. Eliminate many signal-related race
9314 conditions in both forms of restart, and in SIGTERM. See
9315 htdocs/manual/stopping.html for details on stopping and
9316 restarting the parent. [Dean Gaudet]
9318 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
9319 memory allocator to avoid a behaviour that required extra blocks to
9320 be allocated. [Dean Gaudet]
9322 *) Allow suexec to access files relative to current directory but not
9323 above. (Excluding leading / or any .. directory.) [Ken Coar]
9326 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
9327 PR#367, 368, 354, 453

9330 while obtaining the /~user and save the username in a separate data
9331 area so that it won't be overwritten by the call to getgrgid(), and
9332 fix some misuse of the pool string allocation functions. Also fixes
9333 a general problem with parsing URL query info into args for CGI scripts.

9346 object that can't be PUT, or FOOBAR for some method FOOBAR that
9347 apache doesn't know about at all). Log 404s that occur in mod_include.
9348 [Paul Sutton, John Van Essen]
9350 *) If a soft timeout (or lingerout) occurs while trying to flush a
9351 buffer or write inside buff.c or fread'ing from a CGI's output,
9352 then the timeout would be ignored. [Roy Fielding] PR#373
9354 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
9355 parsing of headers. If the terminating empty-line CRLF occurs starting
9356 at the 256th or 257th byte of output, then Navigator will think a normal
9357 image is invalid. We are guessing that this is because their initial
9358 read of a new request uses a 256 byte buffer. We check the bytes written
9359 so far and, if we are about to tickle the bug, we instead insert a
9360 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
9362 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
9363 of an external redirection. [Roy Fielding and Paul Sutton]
9365 *) Configure would create a broken Makefile if the configuration file
9366 contained a commented-out Rule. [Roy Fielding]
9368 *) Promote per_dir_config and subprocess_env from the subrequest to the
9369 main request in mod_negotiation. In particular this fixes a bug
9370 where <Files> sections wouldn't properly apply to negotiated content.
9373 *) Fix a potential deadlock in mod_cgi script_err handling.
9374 [Ralf S. Engelschall]
9376 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
9379 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
9380 .htaccess files because the RewriteBase was not replaced correctly.
9381 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
9382 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
9384 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
9385 1.x the settings are those of pre-1.2b8. For 2.x we include
9386 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
9387 HAVE_SYS_RESOURCE_H (enable the RLimit commands).

9403 *) Improve handling of directories when filenames have spaces in them.
9406 *) For hosts with multiple IP addresses, try all additional addresses if
9407 necessary to get a connect. Fail only if hostent address list is
9408 exhausted. [Chuck Murcko]
9410 *) More signed/unsigned port fixes. [Dean Gaudet]
9412 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
9415 Changes with Apache 1.2b8
9417 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
9418 to it. [Marc Slemko]
9420 *) The addition of <Location> and <File> directives made the
9421 sub_req_lookup_simple() function bogus, so we now handle
9422 the special cases directly. [Dean Gaudet]
9424 *) We now try to log where the server is dumping core when a fatal
9425 signal is received. [Ken Coar]
9427 *) Improved lingering_close by adding a special timeout, removing the
9428 spurious log messages, removing the nonblocking settings (they
9429 are not needed with the better timeout), and adding commentary
9430 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
9431 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
9433 *) Send error messages about setsockopt failures to the server error
9434 log instead of stderr. [Roy Fielding]
9436 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
9438 *) Stopgap solution for CGI 3-second delay with server-side includes: if
9439 processing a subrequest, allocate memory from r->main->pool instead
9440 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
9441 in the middle of an SSI request. [Dean Gaudet] PR #122
9443 *) Fixed status of response when POST is received for a nonexistent URL
9444 (was sending 405, now 404) and when any method is sent with a
9445 full-URI that doesn't match the server and the server is not acting
9446 as a proxy (was sending 501, now 403). [Roy Fielding]
9448 *) Host port changed to unsigned short. [Ken Coar] PR #276
9450 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
9452 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
9454 *) Report extra info from errno with many errors that cause httpd to exit.
9455 spawn_child, popenf, and pclosef now have valid errno returns in the
9456 event of an error. Correct problems where errno was stomped on
9457 before being reported. [Dean Gaudet]
9459 *) In the proxy, if the cache filesystem was full, garbage_coll() was
9460 never called, and thus the filesystem would remain full indefinitely.
9461 We now also remove incomplete cache files left if the origin server
9462 didn't send a Content-Length header and either the client has aborted
9463 transfer or bwrite() to client has failed. [Petr Lampa]
9465 *) Fixed the handling of module and script-added header fields.
9466 Improved the interface for sending header fields and reduced
9467 the duplication of code between sending okay responses and errors.
9468 We now always send both headers_out and err_headers_out, and
9469 ensure that the server-reserved fields are not being overridden,
9470 while not overriding those that are not reserved. [Roy Fielding]
9472 *) Moved transparent content negotiation fields to err_headers_out
9473 to reflect above changes. [Petr Lampa]
9475 *) Fixed the determination of whether or not we should make the
9476 connection persistent for all of the cases where some other part
9477 of the server has already indicated that we should not. Also
9478 improved the ordering of the test so that chunked encoding will
9479 be set whenever it is desired instead of only when KeepAlive
9480 is enabled. Added persistent connection capability for most error
9481 responses (those that do not indicate a bad input stream) when
9482 accessed by an HTTP/1.1 client. [Roy Fielding]
9484 *) Added missing timeouts for sending header fields, error responses,
9485 and the last chunk of chunked encoding, each of which could have
9486 resulted in a process being stuck in write forever. Using soft_timeout
9487 requires that the sender check for an aborted connection rather than
9488 continuing after an EINTR. Timeouts that used to be initiated before
9489 send_http_header (and never killed) are now initiated only within or
9490 around the routines that actually do the sending, and not allowed to
9491 propagate above the caller. [Roy Fielding]
9493 *) mod_auth_anon required an @ or a . in the email address, not both.
9496 *) per_dir_defaults weren't set correctly until directory_walk for
9497 name-based vhosts. This fixes an obscure bug with the wrong config
9498 info being used for vhosts that share the same ip as the server.
9501 *) Improved generation of modules/Makefile to be more generic for
9502 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
9504 *) Generate makefile dependency for Configuration based on the actual
9505 name given when running the Configure process. [Dean Gaudet]
9507 *) Fixed problem with vhost error log not being set prior to
9508 initializing virtual hosts. [Dean Gaudet]
9510 *) Fixed infinite loop when a trailing slash is included after a type map
9511 file URL (extra path info). [Petr Lampa]
9513 *) Fixed server status updating of per-connection counters. [Roy Fielding]
9515 *) Add documentation for DNS issues (reliability and security), and try
9516 to explain the virtual host matching process. [Dean Gaudet]
9518 *) Try to continue gracefully by disabling the vhost if a DNS lookup
9519 fails while parsing the configuration file. [Dean Gaudet]
9521 *) Improved calls to setsockopt. [Roy Fielding]
9523 *) Negotiation changes: Don't output empty content-type in variant list;
9524 Output charset in variant list; Return sooner from handle_multi() if
9525 no variants found; Add handling of '*' wildcard in Accept-Charset.
9526 [Petr Lampa and Paul Sutton]
9528 *) Fixed overlaying of request/sub-request notes and headers in
9529 mod_negotiation. [Dean Gaudet]
9531 *) If two variants' charset quality are equal and one is the default
9532 charset (iso-8859-1), then prefer the variant that was specifically
9533 listed in Accept-Charset instead of the default. [Petr Lampa]
9535 *) Memory allocation problem in push_array() -- it would corrupt memory
9536 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
9538 *) invoke_handler() doesn't handle mime arguments in content-type
9541 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
9544 *) Fixed problem with ErrorDocument not working for virtual hosts
9545 due to one of the performance changes in 1.2b7. [Dean Gaudet]
9547 *) Log an error message if we get a request header that is too long,
9548 since it may indicate a buffer overflow attack. [Marc Slemko]
9550 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
9551 not reject URLs without a double-slash, as per RFC2068 section 3.2.

9563 *) Fixed user and server confusion over what should be a virtual host
9564 and what is the main server, resulting in access to something
9565 other than the name defined in the virtualhost directive (but
9566 with the same IP address) failing. [Dean Gaudet]
9568 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
9569 AIX; improves the redirection stuff to enable the users to generally
9570 redirect to http, https, gopher and ftp; added TIME variable for
9571 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
9572 special patterns >STRING, <STRING and =STRING to RewriteCond, which
9573 can be used in conjunction with %{TIME} or other variables to create
9574 time-dependent rewriting rules. [Ralf S. Engelschall]
9576 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
9577 Module authors may need to adjust their code for proper cleanup to take
9578 place (that is, call note_cleanups_for_fd()). This change fixes problems
9579 with file descriptors being erroneously closed when the proxy module was
9580 in use. [Ben Laurie]
9582 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
9583 initgroups() to hose the group information needed for later

9587 caused a SEGV on some systems.
9589 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.

9615 - Changed send_dir() to remove user/passwd from displayed URL.
9616 - Changed login error messages to be more descriptive.
9617 - remove setting of SO_DEBUG socket option
9618 - Make ftp_getrc() more lenient about multiline responses,
9619 specifically, 230 responses which don't have continuation 230-
9620 on each line). These seem to be all NT FTP servers, and while
9621 perhaps questionable, they appear to be legal by RFC 959.
9622 - Add missing kill_timeout() after transfer to user completes.
9625 *) Fixed problem where a busy server could hang when restarting
9626 after being sent a SIGHUP due to child processes not exiting.
9629 *) Modify mod_include escaping so a '\' only signifies an escaped
9630 character if the next character is one that needs
9631 escaping. [Ben Laurie]
9633 *) Eliminated possible infinite loop in mod_imap when relative URLs are
9634 used with a 'base' directive that does not have a '/' in it.
9635 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
9637 *) Reduced the default timeout from 1200 seconds to 300, and the
9638 one in the sample configfile from 400 to 300. [Marc Slemko]
9640 *) Stop vbprintf from crashing if given a NULL string pointer;
9641 print (null) instead. [Ken Coar]
9643 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
9644 [Marc Slemko and Roy Fielding]
9646 *) Fixed problem with mod_cgi-generated internal redirects trying to
9647 read the request message-body twice. [Archie Cobbs and Roy Fielding]
9649 *) Reduced timeout on lingering close, removed possibility of a blocked
9650 read causing the child to hang, and stopped logging of errors if
9651 the socket is not connected (reset by client). [Roy Fielding]
9653 *) Rearranged main child loop to remove duplication of code in
9654 select/accept and keep-alive requests, fixed several bugs regarding
9655 checking scoreboard_image for exit indication and failure to
9656 account for all success conditions and trap all error conditions,
9657 prevented multiple flushes before closing the socket; close the entire
9658 socket buffer instead of just one descriptor, prevent logging of
9659 EPROTO and ECONNABORTED on platforms where supported, and generally
9660 improved readability. [Roy Fielding]
9662 *) Extensive performance improvements. Cleaned up inefficient use of
9663 auto initializers, multiple is_matchexp calls on a static string,
9664 and excessive merging of response_code_strings. [Dean Gaudet]
9666 *) Added double-buffering to mod_include to improve performance on
9667 server-side includes. [Marc Slemko]
9669 *) Several fixes for suexec wrapper. [Randy Terbush]
9670 - Make wrapper work for files on NFS filesystem.
9671 - Fix portability problem of MAXPATHLEN.
9672 - Fix array overrun problem in clean_env().
9673 - Fix allocation of PATH environment variable
9675 *) Removed extraneous blank line is description of mod_status chars.
9678 *) Logging of errors from the call_exec routine simply went nowhere,
9679 since the logfile fd has been closed, so now we send them to stderr.
9680 [Harald T. Alvestrand]
9682 *) Fixed core dump when DocumentRoot is a CGI.
9683 [Ben Laurie, reported by geddis@tesserae.com]
9685 *) Fixed potential file descriptor leak in mod_asis; updated it and
9686 http_core to use pfopen/pfclose instead of fopen/fclose.
9687 [Randy Terbush and Roy Fielding]
9689 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
9690 as the DEC Alpha which is 64-bit but uses 32-bit ints.
9691 [Dean Gaudet and Ken Coar]
9693 *) Return a 302 response code to the client when sending a redirect
9694 due to a missing trailing '/' on a directory instead of a 301; now
9695 it is cacheable. [Markus Gyger]
9697 *) Fix condition where, if a bad directive occurs in .htaccess, and
9698 sub_request() goes first to this directory, then log_reason() will
9699 SIGSEGV because it doesn't have initialized r->per_dir_config.
9700 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
9702 *) Fix handling of lang_index in is_variant_better(). This was
9703 causing problems which resulted in the server sending the
9704 wrong language document in some cases. [Petr Lampa]
9706 *) Remove free() from clean_env() in suexec wrapper. This was nuking
9707 the clean environment on some systems.
9709 *) Tweak byteserving code (e.g. serving PDF files) to work around
9710 bugs in Netscape Navigator and Microsoft Internet Explorer.
9711 Emit Content-Length header when sending multipart/byteranges.
9714 *) Port to HI-UX/WE2. [Nick Maclaren]
9716 *) Port to HP MPE operating system for HP 3000 machines
9717 [Mark Bixby <markb@cccd.edu>]
9719 *) Fixed bug which caused a segmentation fault if only one argument
9720 given to RLimit* directives. [Ed Korthof]
9722 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
9724 *) Improved buffered output to the client by delaying the flush decision
9725 until the BUFF code is actually about to read the next request.
9726 This fixes a problem introduced in 1.2b5 with clients that send
9727 an extra CRLF after a POST request. Also improved chunked output
9728 performance by combining writes using writev() and removing as
9729 many bflush() calls as possible. NOTE: Platforms without writev()
9730 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
9731 or Configure, unless we have already done so. [Dean Gaudet]
9733 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
9735 *) Fixed mod_info output corruption bug introduced by buffer overflow
9736 fixes. [Dean Gaudet]
9738 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
9739 for the special case of a 304 response. [Paul Sutton]
9741 *) Improved handling of TRACE method by bypassing normal method handling
9742 and header parsing routines; fixed Allow response to always allow TRACE.
9745 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
9747 *) Cleaned-up some of the generated HTML. [Ken Coar]
9749 Changes with Apache 1.2b6
9751 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
9753 *) Fix typo introduced in fix for potential infinite loop around
9754 accept() in child_main(). This change caused the rev to 1.2b6.
9755 1.2b5 was never a public beta.
9757 Changes with Apache 1.2b5
9759 *) Change KeepAlive semantics (On|Off instead of a number), add
9760 MaxKeepAliveRequests directive. [Alexei Kosut]
9762 *) Various NeXT compilation patches, as well as a change in
9763 regex/regcomp.c since that file also used a NEXT define.
9766 *) Allow * to terminate the end of a directory match in mod_dir.
9767 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
9769 *) Don't call can_exec() if suexec_enabled. Calling this requires
9770 scripts executed by the suexec wrapper to be world executable, which
9771 defeats one of the advantages of running the wrapper. [Randy Terbush]
9773 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
9776 *) Migration from sprintf() to snprintf() to avoid buffer
9777 overflows. [Marc Slemko]
9779 *) Provide portable snprintf() implementation (ap_snprintf)
9780 as well as *cvt family. [Jim Jagielski]
9782 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
9785 *) Remove mod_fastcgi.c from the distribution. This module appears
9786 to be maintained more through the Open Market channels and should
9787 continue to be easily available at http://www.fastcgi.com/
9789 *) Fixed bug in modules/Makefile that wouldn't allow building in more
9790 than one subdirectory (or cleaning, either). [Jeremy Laidman]
9792 *) mod_info assumed that the config files were relative to ServerRoot.
9795 *) CGI scripts called as an error document resulting from failed
9796 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
9798 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
9801 *) Properly check errno to prevent display of a directory index
9802 when server receives a long enough URL to confuse stat().
9805 *) Several security enhancements to suexec wrapper. It is _highly_
9806 recommended that previously installed versions of the wrapper
9807 be replaced with this version. [Randy Terbush, Jason Dour]
9809 - ~user execution now properly restricted to ~user's home
9810 directory and below.
9811 - execution restricted to UID/GID > 100
9812 - restrict passed environment to known variables
9813 - call setgid() before initgroups() (portability fix)
9814 - remove use of setenv() (portability fix)
9816 *) Add HTTP/1.0 response forcing. [Ben Laurie]
9818 *) Add access control via environment variables. [Ben Laurie]
9820 *) Add rflush() function. [Alexei Kosut]
9822 *) remove duplicate pcalloc() call in new_connection().
9824 *) Fix incorrect comparison which could allow number of children =
9825 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
9826 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
9828 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
9829 AIX PS/2, CONVEXOS. [Jim Jagielski]
9831 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
9832 It's more portable. [Martin Kraemer]
9834 *) Replace references to make in Makefile.tmpl with $(MAKE).
9837 *) Add ProxyBlock directive w/IP address caching. Add IP address
9838 caching to NoCache directive as well. ProxyBlock works with all
9839 handlers; NoCache now also works with FTP for anonymous logins.
9840 Still more code cleanup. [Chuck Murcko]
9842 *) Add "header parse" API hook [Ben Laurie]
9844 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
9846 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
9848 *) Correctly allow access and auth directives in <Files> sections in
9849 server config files. [Alexei Kosut]
9851 *) Fix bug with ServerPath that could cause certain files to be not
9852 found by the server. [Alexei Kosut]
9854 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
9855 double-quote from text and so that it properly checks for unsupported
9856 status codes using the new index_of_response interface. [Roy Fielding]
9858 *) Multiple fixes to the lingering_close code in order to avoid being
9859 interrupted by a stray timeout, to avoid lingering on a connection
9860 that has already been aborted or never really existed, to ensure that
9861 we stop lingering as soon as any error condition is received, and to
9862 prevent being stuck indefinitely if the read blocks. Also improves
9863 reporting of error conditions. [Marc Slemko and Roy Fielding]
9865 *) Fixed initialization of parameter structure for sigaction.
9866 [mgyger@itr.ch, Adrian Filipi-Martin]
9868 *) Fixed reinitializing the parameters before each call to accept and
9869 select, and removed potential for infinite loop in accept.
9870 [Roy Fielding, after useful PR from adrian@virginia.edu]
9872 *) Fixed condition where, if a child fails to fork, the scoreboard would
9873 continue to say SERVER_STARTING forever. Eventually, the main process
9874 would refuse to start new children because count_idle_servers() will
9875 count those SERVER_STARTING entries and will always report that there
9876 are enough idle servers. [Phillip Vandry]
9878 *) Fixed bug in bcwrite regarding failure to account for partial writes.
9879 Avoided calling bflush() when the client is pipelining requests.
9880 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
9882 *) Added description of "." mode in server-status [Jim Jagielski]
9884 Changes with Apache 1.2b4
9886 *) Fix possible race condition in accept_mutex_init() that
9887 could leave a small security hole open allowing files to be
9888 overwritten in cases where the server UID has write permissions.
9891 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
9893 *) Fix portablity problem in util_script where ARG_MAX may not be
9894 defined for some systems.
9896 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
9899 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
9900 style magic #! token for better script portability. [Garey Smiley]
9902 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
9903 execution for ~userdir CGI. [Jason Dour]
9905 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
9907 *) Fix month off by one in suexec wrapper logging.
9909 Changes with Apache 1.2b3:
9911 *) Fix error in mod_cgi which could cause resources not to be properly
9912 freed, or worse. [Dean Gaudet]
9914 *) Fix find_string() NULL pointer dereference. [Howard Fear]
9916 *) Add set_flag_slot() at the request of Dirk and others.
9919 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
9921 *) Add changes to improve the error message given for invalid
9922 ServerName parameters. [Dirk vanGulik]
9924 *) Add "Authoritative" directive for Auth modules that don't
9925 currently have it. This gives admin control to assign authoritative
9926 control to an authentication scheme and allow "fall through" for
9927 those authentication modules that aren't "Authoritative" thereby
9928 allowing multiple authentication mechanisms to be chained.
9931 *) Remove requirement for ResourceConfig/AccessConfig if not using
9932 the three config file layout. [Randy Terbush]
9934 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
9936 *) Changes to suexec wrapper to fix the following problems:
9937 1. symlinked homedirs will kill ~userdirs.
9938 2. initgroups() on Linux 2.0.x clobbers gr->grid.
9939 3. CGI command lines paramters problems
9940 4. pw-pwdir for "docroot check" still the httpd user's pw record.
9941 [Randy Terbush, Jason Dour]
9943 *) Change create_argv() to accept variable arguments. This fixes
9944 a problem where arguments were not getting passed to the CGI via
9945 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
9947 *) Collapse multiple slashes in path URLs to properly apply
9948 handlers defined by <Location>. [Alexei Kosut]
9950 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
9952 *) Improve the accuracy of request duration timings by setting
9953 r->request_time in read_request_line() instead of read_request().
9956 *) Reset timeout while reading via get_client_block() in mod_cgi.c
9957 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
9959 *) Add the ability to pass different Makefile.tmpl files to Configure
9960 using the -make flag. [Rob Hartill]
9962 *) Fix coredump triggered when sending a SIGHUP to the server caused
9963 by an assertion failure, in turn caused by an uninitialised field in a
9967 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
9968 PATH_INFO from previous versions of Apache (in certain situations,
9969 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
9970 [later removed in 1.2b11]
9972 *) Add rwrite() function to API to allow for sending strings of
9973 arbitrary length. [Doug MacEachern]
9975 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
9977 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
9978 NeXT. [Jim Jagielski]
9980 *) Removed recent modification to promote the status code on internal
9981 redirects, since the correct fix was to change the default log format
9982 in mod_log_config so that it outputs the original status. [Rob Hartill]
9984 Changes with Apache 1.2b2:
9986 *) Update set_signals() to use sigaction() for setting handlers.
9987 This appears to fix a re-entrant problem in the seg_fault()
9988 bus_error() handlers. [Randy Terbush]
9990 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
9992 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
9994 *) proxy_http.c bugfixes: [Chuck Murcko]
9995 1) fixes possible NULL pointer reference w/NoCache
9996 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
9997 host would cache nothing if it was in the local domain,
9998 and the local domain was in the NoCache list)
9999 3) Adds Host: header when not available
10000 4) Some code cleanup and clarification
10002 *) mod_include.c bugfixes:
10003 1) Fixed an ommission that caused include variables to not
10004 be parsed in config errmsg directives [Howard Fear]
10005 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
10006 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
10007 4) Allow backslash-escaping to all quoted text
10008 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
10009 5) Pass variable to command line if not set in XSSI's env
10012 *) Fix infinite loop when processing Content-language lines in
10013 type-map files. [Alexei Kosut]
10015 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
10017 *) Fixed problem in set_[user|group] that prevented CGI execution
10018 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
10020 *) Added PORTING information file. [Jim Jagielski]
10022 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
10024 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
10026 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
10027 USE_FCNTL_SERIALIZED_ACCEPT was intended.
10029 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
10030 which caused problems of systems where socket s_addr is >32bits.
10032 *) Added comment to explain (r->chunked = 1) side-effect in
10033 http_protocol.c [Roy Fielding]
10035 *) Replaced use of index() in mod_expires.c with more appropriate
10036 and portable isdigit() test. [Ben Laurie]
10038 *) Updated Configure for ...
10039 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
10040 *-dg-dgux* (bad pattern match)
10041 QNX (DEF_WANTHSREGEX=yes)
10042 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
10044 *-unixware211 (new)
10045 and added some user diagnostic info. [Ben Laurie]
10047 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
10048 for better portability. [Jim Jagielski]
10050 *) Updated helpers/GuessOS for ...
10051 SCO 5 (recognize minor releases)
10052 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
10053 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
10054 IRIX64 (-sgi-irix64)
10055 ULTRIX (-unknown-ultrix)
10056 SINIX (-whatever-sysv4)
10057 NCR Unix (-ncr-sysv4)
10058 and fixed something in helpers/PrintPath [Ben Laurie]
10060 Changes with Apache 1.2b1
10062 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>

10070 leak. [Nathan Neulinger]
10072 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
10074 *) Problems with mod_auth_msql fixed [Dirk vanGulik]

10078 Changes with Apache 1.1.0
10080 *) Bring NeXT support up to date. [Takaaki Matsumoto]
10082 *) Bring QNX support up to date. [Ben Laurie]
10084 *) Make virtual hosts default to main server keepalive parameters.
10085 [Alexei Kosut, Ben Laurie]
10087 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
10089 *) Fix missing address family for connect, also remove unreachable statement
10090 in mod_proxy. [Ben Laurie]
10092 *) mod_env now turned on by default in Configuration.tmpl.
10094 *) Bugs which were fixed:
10095 a) yet more mod_proxy bugs [Ben Laurie]
10096 b) CGI works again with inetd [Alexei Kosut]
10097 c) Leading colons were stripped from passwords [osm@interguide.com]
10098 d) Another fix to multi-method Limit problem [jk@tools.de]
10100 Changes with Apache 1.1b4
10102 *) r->bytes_sent variable restored. [Robert Thau]
10104 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
10106 *) More possibly unsecure programs removed from the support directory.
10108 *) More mod_auth_msql authentication improvements.
10110 *) VirtualHosts based on Host: headers no longer conflict with the
10113 *) OS/2 compatibility enhancements. [Gary Smiley]
10115 *) POST now allowed to directory index CGI scripts.
10117 *) Actions now work with files of the default type.
10119 *) Bugs which were fixed:
10120 a) more mod_proxy bugs
10121 b) early termination of inetd requests
10122 c) compile warnings on several systems
10123 d) problems when scripts stop reading output early
10125 Changes with Apache 1.1b3
10127 *) Much of cgi-bin and all of cgi-src has been removed, due to
10128 various security holes found and that we could no longer support
10131 *) The "Set-Cookie" header is now special-cased to not merge multiple
10132 instances, since certain popular browsers can not handle multiple
10133 Set-Cookie instructions in a single header. [Paul Sutton]
10135 *) rprintf() added to buffer code, occurrences of sprintf removed.
10138 *) CONNECT method for proxy module, which means tunneling SSL should work.
10139 (No crypto needed) Also a NoCache config directive.
10141 *) Several API additions: pstrndup(), table_unset() and get_token()
10142 functions now available to modules.
10144 *) mod_imap fixups, in particular Location: headers are now complete
10147 *) New "info" module which reports on installed module set through a
10148 special URL, a la mod_status.
10150 *) "ServerPath" directive added - allows for graceful transition
10151 for Host:-header-based virtual hosts.
10153 *) Anonymous authentication module improvements.
10155 *) MSQL authentication module improvements.
10157 *) Status module design improved - output now table-based. [Ben Laurie]
10159 *) htdigest utility included for use with digest authentication
10162 *) mod_negotiation: Accept values with wildcards to be treated with
10163 less priority than those without wildcards at the same quality
10164 value. [Alexei Kosut]
10166 *) Bugs which were fixed:
10167 a) numerous mod_proxy bugs
10168 b) CGI early-termination bug [Ben Laurie]
10169 c) Keepalives not working with virtual hosts
10170 d) RefererIgnore problems
10171 e) closing fd's twice in mod_include (causing core dumps on

10177 a) core dumps in mod_digest
10178 b) truncated hostnames/ip address in the logs
10179 c) relative URL's in mod_imap map files
10181 Changes with Apache 1.1b1
10183 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
10185 Changes with Apache 1.0.3
10187 *) Internal redirects which occur in mod_dir.c now preserve the
10188 query portion of a request (the bit after the question mark).
10191 *) Escape active characters '<', '>' and '&' in html output in
10192 directory listings, error messages and redirection links.
10195 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
10197 *) Fix for POSIX compliance in waiting for processes in alloc.c.
10200 *) setsockopt no longer takes a const declared argument [Martijn Koster]
10202 *) Reset timeout timer after each successful fwrite() to the network.
10203 This patch adds a reset_timeout() procedure that is called by
10204 send_fd() to reset the timeout ever time data is written to the net.
10207 *) timeout() signal handler now checks for SIGPIPE and reports
10208 lost connections in a more user friendly way. [Rob Hartill]
10210 *) Location of the "scoreboard" file which used to live in /tmp is
10211 now configurable (for OSes that can't use mmap) via ScoreBoardFile
10212 which works similar to PidFile (in httpd.conf) [Rob Hartill]
10214 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
10216 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
10217 which caused a SEGV with cookies enabled
10219 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
10222 *) Log the UNIX textual error returned by some system calls, in
10223 particular errors from accept() [David Robinson]
10225 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
10227 Changes with Apache 1.0.2
10229 *) patch to get Apache compiled on UnixWare 2.x, recommended as
10230 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
10232 *) Fix get_basic_auth_pw() to set the auth_type of the request.
10235 *) past changes to http_config.c to only use the
10236 setrlimit function on systems defining RLIMIT_NOFILE
10237 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
10238 for SUNOS and prototypes the needed functions.
10240 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
10243 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
10245 *) Merge multiple headers from CGI scripts instead of taking last
10246 one. [David Robinson]
10248 *) Add support for SCO 5. [Ben Laurie]
10250 Changes with Apache 1.0.1
10252 *) Silence mod_log_referer and mod_log_agent if not configured
10255 *) Recursive includes can occur if the client supplies PATH_INFO data
10256 and the server provider uses relative links; as file.html
10257 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
10259 *) The replacement for initgroups() did not call {set,end}grent(). This
10260 had two implications: if anything else used getgrent(), then
10261 initgroups() would fail, and it was consuming a file descriptor.
10264 *) On heavily loaded servers it was possible for the scoreboard to get
10265 out of sync with reality, as a result of a race condition.
10266 The observed symptoms are far more Apaches running than should
10267 be, and heavy system loads, generally followed by catastrophic
10268 system failure. [Ben Laurie]
10270 *) Fix typo in license. [David Robinson]
10272 Changes with Apache 1.0.0 23 Nov 1995
10274 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
10276 Changes with Apache 0.8.16 05 Nov 1995
10278 *) New man page for 'httpd' added to support directory [David Robinson]
10280 *) .htgroup files can have more than one line giving members for a
10281 given group (each must have the group name in front), for NCSA
10282 back-compatibility [Robert Thau]
10284 *) Mutual exclusion around accept() is on by default for SVR4 systems
10285 generally, since they generally can't handle multiple processes in
10286 accept() on the same socket. This should cure flaky behavior on
10287 a lot of those systems. [David Robinson]
10289 *) AddType, AddEncoding, and AddLanguage directives take multiple
10290 extensions on a single command line [David Robinson]
10292 *) UserDir can be disabled for a given virtual host by saying
10293 "UserDir disabled" in the <VirtualHost> section --- it was a bug
10294 that this didn't work. [David Robinson]
10296 *) Compiles on QNX [Ben Laurie]
10298 *) Corrected parsing of ctime time format [David Robinson]
10300 *) httpd does a perror() before exiting if it can't log its pid
10301 to the PidFile, to make diagnosing the error a bit easier.
10304 *) <!--#include file="..."--> can no longer include files in the
10305 parent directory, for NCSA back-compatibility. [David Robinson]
10307 *) '~' is *not* escaped in URIs generated for directory listings
10310 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
10312 *) Fixed bug involving handling URIs with escaped %-characters
10313 in redirects [David Robinson]
10315 Changes with Apache 0.8.15 14 Oct 1995
10317 *) Switched to new, simpler license
10319 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
10321 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
10323 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
10325 *) Correctly handles internal redirects to files with names containing '%'
10328 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
10330 *) Use geteuid() rather than getuid() to see if we have root privilege,
10331 so that server correctly resets privilege if run setuid root. [Andrew
10334 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
10337 *) Fix relative URLs in imagemap files [Randy Terbush]
10339 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
10342 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
10343 entries all name the same one. [David Robinson]
10345 *) Fix directory listings with filenames containing unusual characters
10348 *) Better URI-escaping for generated URIs in directories with filenames
10349 containing unusual characters [Ben Laurie]
10351 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
10353 *) Unblock alarms on error return from spawn_child() [David Robinson]
10355 *) Sample Config files have extra note for SCO users [Ben Laurie]
10357 *) Configuration has note for HP-UX users [Rob Hartill]
10359 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
10361 *) Nuked bogus #define in httpd.h [David Robinson]
10363 *) Better test for whether a system has setrlimit() [David Robinson]
10365 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
10367 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
10370 Changes with Apache 0.8.14 19 Sep 1995
10372 *) Compiles on SCO ODT 3.0 [Ben Laurie]
10374 *) AddDescription works (better) [Ben Laurie]
10376 *) Leaves an intelligible error diagnostic when it can't set group
10377 privileges on standalone startup [Andrew Wilson]
10379 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
10380 that machine, which claims to be BSD but does not support RLIMIT.
10383 *) gcc -Wall no longer complains about an unused variable when util.c
10384 is compiled with -DMINIMAL_DNS [Andrew Wilson]
10386 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
10388 Changes with Apache 0.8.13 07 Sep 1995
10390 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
10392 *) Have built-in imagemap code recognize & honor Point directive [James
10395 *) Generate cleaner directory listings in directories with a mix of
10396 long and short filenames [Rob Hartill]
10398 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
10400 *) Properly default ServerName for virtual servers [Robert Thau]
10402 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
10403 Paul Richards and a cast of thousands...]
10405 *) On self-identified BSD systems (we don't try to guess any more),
10406 allocate a few extra file descriptors per virtual host with setrlimit,
10407 if we can, to avoid running out. [Randy Terbush]
10409 *) Write 22-character lock file name into buffer with enough space
10410 on startup [Konstantin Olchanski]
10412 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
10415 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
10417 *) Suppress -Wall warning by initializing variable in negotiation code
10418 [Tobias Weingartner]
10420 Changes with Apache 0.8.12 31 Aug 1995
10422 *) Doesn't pause three seconds after including a CGI script which is
10423 too slow to die off (this is done by not even trying to kill off
10424 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
10425 after the entire document has been processed). [Robert Thau]
10427 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
10429 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
10431 *) Allows .htaccess files to override <Directory> sections naming the
10432 same directory [David Robinson]
10434 *) Removed an efficiency hack in sub_req_lookup_uri which was
10435 causing certain extremely marginal cases (e.g., ScriptAlias of a
10436 *particular* index.html file) to fail. [David Robinson]
10438 *) Doesn't log an error when the requested URI requires
10439 authentication, but no auth header line was supplied by the
10440 client; this is a normal condition (the client doesn't no auth is
10441 needed here yet). [Robert Thau]
10443 *) Behaves more sanely when the name server loses its mind [Sean Welch]
10445 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
10447 *) RFC931 code no longer passes out name of prior clients on current
10448 requests if the current request came from a server that doesn't
10449 do RFC931. [David Robinson]
10451 *) Configuration script accepts "Module" lines with trailing whitespace.
10454 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
10456 *) Cleaned up comments in mod_cgi.c [Robert Thau]
10458 Changes with Apache 0.8.11 24 Aug 1995
10460 *) Wildcard <Directory> specifications work. [Robert Thau]
10462 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
10464 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
10465 the file being requested itself, in addition to the directories leading
10466 up to it. [Robert Thau]
10468 *) Logs access failures due to symlink checks or invalid client address
10469 in the error log [Roy Fielding, Robert Thau]
10471 *) Symlink checks deal correctly with systems where lstat of
10472 "/path/to/some/link/" follows the link. [Thau, Fielding]
10474 *) Doesn't reset DirectoryIndex to 'index.html' when
10475 other directory options are set in a .htaccess file. [Robert Thau]
10477 *) Clarified init code and nuked bogus warning in mod_access.c
10478 [Florent Guillaume]
10480 *) Corrected several directives in sample srm.conf
10481 --- includes corrections to directory indexing icon-related directives
10482 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
10483 icons for encodings right, and turning on AddEncoding by default).
10486 *) Corrected descriptions of args to AddIcon and AddAlt in command table
10489 *) INSTALL & README mention "contributed modules" directory [Brian
10492 *) Fixed English in the license language... "for for" --> "for".
10495 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
10496 mod_alias.c, merging it almost completely with handling of Alias, and
10497 adding a 'notes' field to the request_rec which allows the CGI module
10498 to discover whether the Alias module has put this request through
10499 ScriptAlias (which it needs to know for back-compatibility, as the old
10500 NCSA code did not check Options ExecCGI in ScriptAlias directories).
10503 Changes with Apache 0.8.10 18 Aug 1995
10505 *) AllowOverride applies to the named directory, and not just
10506 subdirectories. [David Robinson]
10508 *) Do locking for accept() exclusion (on systems that need it)
10509 using a special file created for the purpose in /usr/tmp, and
10510 not the error log; using the error log causes real problems
10511 if it's NFS-mounted; this is known to be the cause of a whole
10512 lot of "server hang" problems with Solaris. [David Robinson;
10513 thanks to Merten Schumann for help diagnosing the problem].
10515 Changes with Apache 0.8.9 12 Aug 1995
10517 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
10519 *) Nested includes see environment variables of the including document,
10520 for NCSA bug-compatibility (some sites have standard footer includes
10521 which try to print out the last-modified date). [Eric Hagberg/Robert
10524 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
10525 URI as a CGI script, even if it would have been treated as something
10526 else if requested directly, for NCSA back-compatibility. (Note that
10527 this means that people who know the name of the script can see the
10528 code just by asking for it). [Robert Thau]
10530 *) New version of dbmmanage script included in support directory as
10533 *) Check if scoreboard file couldn't be opened, and say so, rather
10534 then going insane [David Robinson]
10536 *) POST to CGI works on A/UX [Jim Jagielski]
10538 *) AddIcon and AddAlt commands work properly [Rob Hartill]
10540 *) NCSA server push works properly --- the Arena bug compatibility
10541 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
10542 if you still want the workaround). [Rob Hartill]
10544 *) If client didn't submit any Accept-encodings, ignore encodings in
10545 content negotiation. (NB this will all have to be reworked anyway
10546 for the new HTTP draft). [Florent Guillaume]
10548 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
10550 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
10552 *) Give Redirect priority over Alias, for NCSA bug compatibility
10555 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
10556 paralleling earlier bug fix for CGI [David Robinson]
10558 *) If DBM auth is improperly configured, report a server error and don't
10561 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
10562 it seems to work well enough without it (even in a 10 hits/sec
10563 workout), and the overhead for the locking under A/UX is
10564 alarmingly high (though it is very low on other systems).
10565 [Eric Hagberg, Jim Jagielski]
10567 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
10569 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
10570 Behlendorf/Eric Hagberg]
10572 *) More improvements to default Configuration for A/UX [Jim Jagielski]
10574 *) Compiles clean on NEXT [Rob Hartill]
10576 *) Compiles clean on SGI [Robert Thau]
10578 Changes with Apache 0.8.8 08 Aug 1995
10580 *) SunOS library prototypes now never included unless explicitly
10581 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
10582 people using GNU libc on SunOS are screwed by prototypes for the
10585 (Those who wish to compile clean with gcc -Wall on a standard
10586 SunOS setup need the prototypes, and may obtain them using
10587 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
10588 with nonstandard libraries are presumably competent to make their
10591 *) Strips trailing '/' characters off both args to the Alias command,
10592 to make 'Alias /foo/ /bar/' work.
10594 Changes with Apache 0.8.7 03 Aug 1995
10596 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
10597 [reported by David Robinson]
10599 *) Compiles clean on OSF/1 [David Robinson]
10601 *) Added some of the more recent significant changes (AddLanguage stuff,
10602 experimental LogFormat support) to CHANGES file in distribution root
10605 Changes with Apache 0.8.6 02 Aug 1995
10607 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
10608 (If you actually wanted a conditional GET which bypassed the cache, you
10609 couldn't get it). [Reported by Roy Fielding]
10611 *) Properly terminate headers on '304 Not Modified' replies to conditional
10612 GETs --- no browser we can find cares much, but the CERN proxy chokes.
10613 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
10615 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
10617 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
10618 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
10619 and older versions don't set the __SUNPRO_C preprocessor variable). On
10620 all other systems, these are never used anyway. [Reported by Mark Cox].
10622 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
10624 Changes with Apache 0.8.5 01 Aug 1995
10626 *) Added last-minute configurable log experiment, as optional module
10628 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
10629 properly. (One-line fix to http_protocol.c).
10631 *) Work around bogus behavior when reloading from Netscape.
10632 It's Netscape's bug --- for some reason they expect a request with
10633 If-modified-since: to not function as a conditional GET if it also
10634 comes with Pragma: no-cache, which is way out of line with the HTTP
10635 spec (according to Roy Fielding, the redactor).
10637 *) Added parameter to set maximum number of server processes.
10639 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
10642 *) IdentityCheck bugfix [Chuck Murcko].
10644 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
10646 *) More sample config file corrections; add extension to AddType for
10647 *.asis, move AddType generic description to its proper place, and
10648 fix miscellaneous typos. [ Alexei Kosut ]
10650 *) Deleted the *other* reference to the regents from the Berkeley
10651 legal disclaimer (everyplace).
10653 *) Nuked Shambhala name from src/README; had already cleaned it out
10654 of everywhere else.
10656 Changes with Apache 0.8.4
10658 *) Changes to server-pool management parms --- renamed current
10659 StartServers to MinSpareServers, created separate StartServers
10660 parameter which means what it says, and renamed MaxServers to
10661 MaxSpareServers (though the old name still works, for NCSA 1.4
10662 back-compatibility). The old names were generally regarded as
10663 too confusing. Also altered "docs" in sample config files.
10665 *) More improvements to default config files ---
10666 sample directives (commented out) for XBitHack, BindAddress,
10667 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
10668 defaults, AddTypes for send-as-is and imagemap magic types, and
10669 improvements to samples for DirectoryIndex [Alexei Kosut]
10671 *) Yet more improvements to default config files --- changes to
10672 Alexei's sample AddLanguage directives, and sample LanguagePriority
10673 [ Florent Guillaume ]
10675 *) Set config file locations properly if not set in httpd.conf
10678 *) Don't escape URIs in internal redirects multiple times; don't
10679 do that when translating PATH_INFO to PATH_TRANSLATED either.
10682 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
10684 Changes with Apache 0.8.3
10686 *) Edited distribution README to *briefly* summarize installation
10687 procedures, and give a pointer to the INSTALL file in the src/
10690 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
10691 recent NCSA distributions.
10693 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
10694 exist for the same directory, use both and don't segfault. [Reported
10697 *) Proper makefile dependencies [David Robinson]
10699 *) Note (re)starts in error log --- reported by Rob Hartill.
10701 *) Only call no2slash() after get_path_info() has been done, to
10702 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
10703 reported by Andrew Wilson, though this one is probably a real bug]
10705 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
10706 dump core when Referer is not supplied. [Randy Terbush]
10708 *) Lightly edited sample config files to refer people to our documentation
10709 instead of NCSA's, and to list Rob McCool as *original* author (also
10710 deleted his old, and no doubt non-functional email address). Would be
10711 nice to have examples of new features...
10713 Changes with Apache 0.8.2 19 Jul 1995
10715 *) Added AddLanuage code [Florent Guillaume]
10717 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
10719 *) All sorts of problems when MultiViews finds a directory. It would
10720 be nice if mod_dir.c was robust enough to handle that, but for now,
10721 just punt. [reported by Brian Behlendorf]
10723 *) Wait for all children on restart, to make sure that the old socket
10724 is gone and we can reopen it. [reported by Randy Terbush]
10726 *) Imagemap module is enabled in default Configuration
10728 *) RefererLog and UserAgentLog modules properly default the logfile
10731 *) Mark Cox's mod_cookies added to the distribution as an optional
10732 module (commented out in the default Configuration, and noted as
10733 an experiment, along with mod_dld). [Mark Cox]
10735 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
10737 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
10739 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
10741 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
10744 Changes with Apache 0.8.1
10746 *) New imagemap module [Randy Terbush]
10748 *) Replacement referer log module with NCSA-compatible RefererIgnore
10749 [Matthew Gray again]
10751 *) Don't mung directory listings with very long filenames.
10752 [Florent Guillaume]
10754 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
10756 *) New config script. See INSTALL for info. [Robert Thau]
10758 *) Scoreboard mechanism for regulating the number of extant server
10759 processes. MaxServers and StartServers defaults are the same as
10760 for NCSA, but the meanings are slightly different. (Actually,
10761 I should probably lower the MaxServers default to 10).
10763 Before asking for a new connection, each server process checks
10764 the number of other servers which are also waiting for a
10765 connection. If there are more than MaxServers, it quietly dies
10766 off. Conversely, every second, the root, or caretaker, process
10767 looks to see how many servers are waiting for a new connection;
10768 if there are fewer than StartServers, it starts a new one. This
10769 does not depend on the number of server processes already extant.
10770 The accounting is arranged through a "scoreboard" file, named
10771 /tmp/htstatus.*, on which each process has an independent file
10772 descriptor (they need to seek without interference).
10774 The end effect is that MaxServers is the maximum number of
10775 servers on an *inactive* server machine, but more will be forked
10776 off to handle unusually heavy loads (or unusually slow clients);
10777 these will die off when they are no longer needed --- without
10778 reverting to the overhead of full forking operation. There is a
10779 hard maximum of 150 server processes compiled in, largely to
10780 avoid forking out of control and dragging the machine down.
10781 (This is arguably too high).
10783 In my server endurance tests, this mechanism did not appear to
10784 impose any significant overhead, even after I forced it to put the
10785 scoreboard file on a normal filesystem (which might have more
10786 overhead than tmpfs). [Robert Thau]
10788 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
10791 *) Read .htaccess files even in directory with <Directory> section.
10792 (Former incompatibility noted on mailing list, now fixed). [Robert
10795 *) "HEAD /" gives the client a "Bad Request" error message, rather
10796 than trying to send no body *and* no headers. [Cliff Skolnick].
10798 *) Don't produce double error reports for some very obscure cases
10799 mainly involving auth configuration (the "all modules decline to
10800 handle" case which is a sure sign of a server bug in most cases,
10801 but also happens when authentication is badly misconfigured).
10804 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
10805 it's *for*, and this sort of thing really shouldn't be cluttering
10806 up the Makefile). [Robert Thau]
10808 *) Incidental code cleanups in http_main.c --- stop dragging
10809 sa_client around; just declare it where used. [Robert Thau]
10811 *) Another acc-related fix. (It doesn't like const char
10812 in some places...). [Mark Cox]
10814 Changes with Shambhala 0.6.1 13 Jul 1995
10816 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
10817 Also, fixed auth typo in http_protocol.c unmasked by this fix.
10819 *) Compiles clean with acc on SunOS [Paul Sutton]
10821 *) Reordered modules in modules.c so that Redirect takes priority
10822 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
10823 believe it or not, he has an actual site with a ScriptAlias and
10824 a Redirect declared for the *exact same directory*. Even *my*
10825 compatibility fetish wouldn't motivate me to fix this if the fix
10826 required any effort, but it doesn't, so what the hey.
10828 *) Fixed to properly default several server_rec fields for virtual
10829 servers from the corresponding fields in the main server_rec.
10830 [Cliff Skolnick --- 'port' was a particular irritant].
10832 *) No longer kills off nph- child processes before they are
10833 finished sending output. [Matthew Gray]
10835 Changes with Shambhala 0.6.0 10 Jul 1995
10837 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
10838 the connection to the client in an "aborted" state, but otherwise
10839 allow whatever handlers are running to clean up. hard_timeout()s
10840 abort the request in progress completely; anything not tied to some
10841 resource pool cleanup will leak. They're still around because I
10842 haven't yet come up with a more elegant way of handling
10843 timeouts when talking to something that isn't the client. The
10844 default_handler and the dir_handler now use soft timeouts, largely
10845 so I can test the feature. [Robert Thau]
10847 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
10848 the case of log handlers dying prematurely is probably handled VERY
10849 gracelessly at this point, and if the logger stops reading input,
10850 the server will hang. (It is known to correctly restart the
10851 logging process on server restart; this is (should be!) going through
10852 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
10853 script). [Robert Thau]
10855 *) asis files supported (new module). [Robert Thau]
10857 *) IdentityCheck code is compiled in, but has not been tested. (I
10858 don't know anyone who runs identd). [Robert Thau]
10860 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
10861 came in with the request, for NCSA bug-compatibility. [Robert Thau]
10863 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
10865 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
10866 as timeouts are not in scope. [Robert Thau]
10868 *) quoted-string args in config files now handled correctly (doesn't drop
10869 the last character). [Robert Thau; reported by Randy Terbush]
10871 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
10872 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
10874 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
10875 default default type); the former default default behavior when all
10876 type-checkers defaulted had been a core dump. [Paul Sutton]
10878 *) Copy filenames out of the struct dirent when indexing
10879 directories. (On Linux, readdir() returns a pointer to the same
10880 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
10882 Changes with Shambhala 0.5.3 [not released]
10884 *) Default response handler notes "file not found" in the error log,
10885 if the file was not found. [Cliff Skolnick].
10887 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
10888 code no longer sets up bogus PATH_INFO which fakes out the directory
10889 handler). [Cliff Skolnick]
10891 Changes with Shambhala 0.5.2 06 Jul 1995
10893 *) Changes to http_main.c --- root server no longer plays silly
10894 games with SIGCHLD, and so now detects and replaces dying
10895 children. Child processes just die on SIGTERM, without taking
10896 the whole process group with them. Potential problem --- if any
10897 child process refuses to die, we hang in restart.
10898 MaxRequestsPerChild may still not work, but it certainly works
10899 better than it did before this! [Robert Thau]
10901 *) mod_dir.c bug fixes: ReadmeName and HeaderName
10902 work (or work better, at least); over-long description lines
10903 properly terminated. [Mark Cox]
10905 *) http_request.c now calls unescape_url() more places where it
10906 should [Paul Sutton].
10908 *) More directory handling bugs (reported by Cox)
10909 Parent Directory link is now set correctly. [Robert Thau]
10911 Changes with Shambhala 0.5.1 04 Jul 1995
10913 *) Generalized cleanup interface in alloc.c --- any function can be
10914 registered with alloc.c as a cleanup for a resource pool;
10915 tracking of files and file descriptors has been reimplemented in
10916 terms of this interface, so I can give it some sort of a test.
10919 *) More changes in alloc.c --- new cleanup_for_exec() function,
10920 which tracks down and closes all file descriptors which have been
10921 registered with the alloc.c machinery before the server exec()s a
10922 child process for CGI or <!--#exec-->. CGI children now get
10923 started with exactly three file descriptors open. Hopefully,
10924 this cures the problem Rob H. was having with overly persistent
10925 CGI connections. [Robert Thau]
10927 *) Mutual exclusion around the accept() in child_main() --- this is
10928 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
10929 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
10930 This uses fcntl(F_SETLK,...) on the error log descriptor because
10931 flock() on that descriptor won't work on systems which have BSD
10932 flock() semantics, including (I think) Linux 1.3 and Solaris.
10934 This does work on SunOS (when the server is idle, only one
10935 process in the pool is waiting on accept()); it *ought* to work
10936 on the other systems. [Robert Thau]
10938 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
10940 *) sizeof(*sa_client) bugfix from [Rob Hartill]
10942 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
10944 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
10945 be unnecessary if I go to the revised timeout-handling scheme).
10948 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
10949 string) even if none came in with the request. [Robert Thau]
10951 *) CHANGES file added to distribution ;-).
10953 Changes with Shambhala 0.4.5
10955 *) mod_dld --- early dynamic loading support [rst]
10956 *) Add wildcard content handlers for XBITHACK; default_hander now
10957 invoked with that mechanism (as a handler hanging off mod_core) [rst]
10958 *) XBITHACK supported as a wildcard content-handler, and
10959 configurable at run-time (not just at compile time, as in the
10960 "patchy server" releases) [rst]
10962 Changes with Shambhala 0.4.4 30 Jun 1995
10964 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
10965 *) Handle Addtype x/y .z [rst, reported by Cox]
10967 Changes with Shambhala 0.4.3
10969 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
10970 synonymous [rst, terbush]
10972 Changes with Shambhala 0.4.1 28 Jun 1995
10974 *) First-cut virtual host implementation; some refit in the config
10975 reading code, and log management, was necessary to support this [rst]
10976 *) Sub-pool machinery, originally added to avoid excessive storage
10977 allocation on listings of large directories (which turned out to
10978 be the problem that the 0.3 storage accounting was added to
10979 find). Subrequests and mod_dir changed to use subpools. [rst]
10980 *) More memory debugging --- free list consistency checks. [rst]
10981 *) Added err_headers to request_rec, with support elsewhere [rst]
10982 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
10984 Changes with Shambhala 0.3 19 Jun 1995
10986 *) Switch ONE_PROCESS to a runtime command-line option (-X)
10987 *) Don't compile in mod_ai_backcompat by default
10988 *) Switch name of server from Apache to Shambhala in Makefile
10989 *) Add some accounting routines to track memory usage in the pools,
10992 Changes with Shambhala 0.2
10994 *) Set DOCUMENT_ROOT CGI variable
10995 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
10996 *) Add critical section protection to handling of cleanup structures
10998 *) Significant code reorg within the server core to group related
10999 functions together [rst]
11000 *) Correctly handle clients that hang up before sending any request
11002 *) Replace dying child processes. [rst]
11004 Changes with Shambhala 0.1 12 Jun 1995
11006 Major rewrite of the pre-existing "patchy server" codebase, by
11007 Robert Thau (rst). Significant portions of the server code, such
11008 as configuration-file handling and HTTP authentication support,
11009 were ripped out and rewritten from scratch. Code that was not
11010 completely rewritten was significantly altered.
11012 Major changes with this release include:
11014 *) Introduction of the module API; in request handling, the central
11015 machinery just dispatches to various modules, which actually do
11016 most of the work. Configuration handling is similar --- modules
11017 declare their own commands, and the central machinery just
11018 dispatches to them.
11020 API features from shambhala/0.1 were substantially unchanged in
11021 Apache 1.0 and 1.1. (1.0 API features not yet present in this
11022 release, such as wildcard handlers and subpools, were added in
11023 subsequent Shambhala releases, and were also generally rst's
11026 *) This release included the following modules:
11028 mod_access (access control --- allow and deny directives),
11029 mod_alias (Alias and Redirect commands),
11030 mod_auth (straight HTTP authentication, based on flat-files)
11031 mod_auth_dbm (same, with dbm files)
11032 mod_cgi (CGI scripts and, in this release, ScriptAlias)
11033 mod_common_log (CLF access logs; later renamed mod_log_common)
11034 mod_dir (directory indexing)
11035 mod_include (server-side includes)
11036 mod_mime (AddType directives)
11037 mod_negotiation (content negotiation)
11038 mod_userdir (support for users' public_html directories)
11040 It also included a mod_ai_backcompat, which was a private hack
11041 for back-compatibility with rst's own AI-lab servers.
11043 All of these modules were substantially complete, and functional
11044 or nearly so (a few, which implemented features not in use at
11045 Thau's site, required patches of a few lines).
11047 *) sub-request machinery, to allow modules to determine how other
11048 modules would assign MIME types to a given file, or optionally
11049 serve its content (this is heavily used by mod_dir, mod_include
11050 and mod_negotiation).
11052 *) Resource pool system for keeping track of memory allocated and
11053 files opened in service of a particular request. Much of the
11054 code in the modules (when they weren't rewrites) was adjusted to
11055 replace a pervasive convention of using fixed-size buffers on
11056 the stack with an equally pervasive convention of using memory
11057 allocated with palloc().
11059 *) Reorganization of data structures associated with a given
11060 request to eliminate use of global variables and the troublesome
11061 unmunge_name function (used in NCSA and early Apache releases to
11062 attempt to determine the URI which mapped to a given filename
11063 --- a difficult proposition, given that it is easy to produce
11064 setups in which multiple URIs map to the same file).
11066 *) Source files renamed and rearranged
11068 *) Very simple pre-forking behavior --- parent process forked off a
11069 fixed number of children, and then just waited for SIGHUP.
11071 *) Other more minor changes too numerous to list.
11073 This release included modified versions of a lot of code from the
11074 Apache 0.6.4 public release, plus an early pre-forking patch
11075 codeveloped by Robert Thau and Rob Hartill.
11077 Changes with Apache 0.7.3 20 Jun 1995
11079 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
11080 were incorporated by Rob Hartill on the main branch while Robert Thau
11081 worked on the Shambhala rewrite above. Most were merged into the
11082 Shambala architecture after Apache 0.8.0.
11084 Changes with Apache 0.6.4 13 May 1995
11086 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
11089 Changes with Apache 0.5.1 10 Apr 1995
11091 Changes with Apache 0.4 02 Apr 1995
11093 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
11096 Changes with Apache 0.3 24 Mar 1995
11098 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
11101 Changes with Apache 0.2 18 Mar 1995
11103 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
11104 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
11105 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
