1 Changes with Apache 2.0b1
3 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
4 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
6 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
8 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
9 after the end of the response. [Ryan Bloom]
11 *) Get byterange requests working with responses that do not have a
12 content-length. Because of the way byterange requests work, we have to
13 have all of the data before we can actually do the byterange, so we
14 can compute the content-length in the byterange filter.
17 *) Get exe CGI's working again on Windows.
20 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
21 they keep track of whether or not their post config hook has been
22 called before. Instead of a static variable (which is replaced when
23 the DSO is loaded a second time), use userdata in the process pool.
26 Changes with Apache 2.0a9
28 *) Win32 now requires perl to complete the final install step for users
29 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
30 and installs the conf, htdocs and htdocs/manual directories.
33 *) Make mod_include use a hash table to associate directive tags with
34 functions. This allows modules to implement their own SSI tags easily.
35 The idea is simple enough, a module can insert it's own tag and function
36 combination into a hash table provided by mod_include. While mod_include
37 parses an SSI file, when it encounters a tag in the file, it does a
38 hash lookup to find the function that implements that tag, and passes
39 all of the relevant data to the function. That function is then
40 responsible for processing the tag and handing the remaining data back
41 to mod_include for further processing.
42 [Paul J. Reder <rederpj@raleigh.ibm.com>]
44 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
45 fewer parameters: the local and remote socket addresses were removed
46 from the parameter list because all required information is available
47 via the APR socket. [Jeff Trawick]
49 *) Distribution directory structure reorganized to reflect a
50 normal source distribution with external install targets.
53 *) The MPMs that need multiple segments of shared memory now create
54 two apr_shmem_t variables, one for each shared memory allocation.
55 the problem is that we can't determine how much memory will be required
56 for shared memory allocations once we try to allocate more than one
57 variable. The MM code automatically aligns the shared memory allocations,
58 so we end up needing to pad the amount of shared memory we want based
59 on how many variables will be allocated out of the shared memory segment.
60 It is just easier to create a second apr_shmem_t variable, and two
64 *) Cleanup the export list a bit. This creates a single unified list of
65 functions exported by APR. The export list is generated at configure
66 time, and that list is then used to generate the exports.c file.
67 Because of the way the export list is generated, we only export those
68 functions that are valid on the platform we are building on.
71 *) Enable logging the cookie with mod_log_config
72 [Sander van Zoest <sander@covalent.net>]
74 *) Fix a segfault in mod_info when it reaches the end of the configuration.
77 *) Added lib/aputil/ as a placeholder for utility functions which are not
78 specific to the Apache HTTP Server (but do not make sense with APR).
79 The first utility is "apu_dbm": a set of functions to work with DBM
80 files. This first version can be compiled for SDBM or GDBM databases.
83 *) Complete re-write of mod_include. This makes mod_include a filter that
84 uses buckets directly. This has now served the FAQ correctly.
85 [Paul Reder <rederpj@raleigh.ibm.com>]
87 *) Allow modules to specify the first filter in a sub_request when
88 making the sub_request. This keeps modules from having to change the
89 output_filter immediately after creating the sub-request, and therefore
90 skip the sub_req_output_filter. [Ryan Bloom]
92 *) Update ab to accept URLs with IPv6 literal address strings (in the
93 format described in RFC 2732), and to build Host header fields in
94 the same format. This allows IPv6 literal address strings to be
95 used with ab. This support has been tested against Apache 1.3 with
96 the KAME patch, but Apache 2.0 does not yet work with this format
97 of the Host header field. [Jeff Trawick]
99 *) Accomodate an out-of-space condition in the piped logs and the
100 rotatelogs.c code, and no longer churn log processes for this
101 condition. [Victor J. Orlikowski]
103 *) Add support for partial writes with apr_sendfile() to core_output_filter.
106 Changes with Apache 2.0a8
108 *) Add a directive to mod_mime so that filters can be associated with
112 *) Get multi-views working again. We were setting the path_info
113 field incorrectly if we couldn't find the specified file.
116 *) Fix 304 processing. The core should never try to send the headers
117 down the filter stack. Always, just setup the table in the request
118 record, and let the header filter convert it to data that is ready
122 *) More fixes for the proxy. There are still bugs in the proxy code,
123 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
127 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
130 *) APR: Add new apr_getopt_long function to handle long options.
131 [B. W. Fitzpatrick <fitz@red-bean.com>]
133 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
134 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
135 hostname resolution/address string parsing and building
136 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
137 of one of the apr_sockaddr_t structures for a socket. Change
138 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
140 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
141 I have proxied pages with it, cleanup will commence soon.
144 *) Make the proxy work with filters. This isn't perfect, because we
145 aren't dealing with the headers properly. [Ryan Bloom]
147 *) Do not send a content-length iff the C-L is 0 and this is a head
148 request. [Ryan Bloom]
150 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
151 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
153 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
155 *) Get the default_handler to stop trying to deal with HEAD requests.
156 The idea is to let the content-length filter compute the C-L before
157 we try to send the data. If we can get the C-L correctly, then we
158 should send it in the HEAD response.
161 *) The Header filter can now determine if a body should be sent based
162 on r->header_only. The general idea of this is that if we delay
163 deciding to send the body, then we might be able to compute the
164 content-length correctly, which will help caching proxies to cache
165 our data better. Any handler that doesn't want to try to compute
166 the content-length can just send an EOS bucket without data and
167 everything will just work.
170 *) Add the referer to the error log if one is available.
171 [Markus Gyger <mgyger@itr.ch>]
173 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
174 change, the root of the configuration tree has been exposed to modules
176 [Ryan Morgan <rmorgan@covalent.net>]
178 *) Get the core_output_filter to use the bucket interface directly.
179 This keeps us from calling the content-length filter multiple times
180 for a simple static request.
183 *) We are sending the content-type correctly now.
184 [Ryan Bloom and Will Rowe]
186 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
187 a bogus bytes-sent value when the only thing being sent was trailers
188 and writev() returned an error (or EAGAIN). [Jeff Trawick]
190 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
191 hints file to determine which platforms define
192 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
195 *) APR: add apr_get_home_directory() [Jeff Trawick]
197 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
199 *) Not all platforms have INADDR_NONE defined by default. Apache
200 used to make this check and define INADDR_NONE if appropriate,
201 but APR needs the check too, and I suspect other applications will
202 as well. APR now defines APR_INADDR_NONE, which is always a valid
203 value on all platforms.
204 [Branko Èibej <brane@xbc.nu>]
206 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
207 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
209 *) Relax the syntax checking of Host: headers in order to support
210 iDNS. PR#6635 [Tony Finch]
212 *) When reading from file buckets we convert to an MMAP if it makes
213 sense. This also simplifies the default handler because the
214 default handler no longer needs to try to create MMAPs.
217 *) BUFF has been removed from the main server. The BUFF code will remain
218 in the code until it has been purged from the proxy module as well.
221 *) Byteranges have been completely re-written to be a filter. This
222 has been tested, and I believe it is working correctly, but it could
223 doesn't work for the Adobe Acrobat plug-in. The output almost matches
224 the output from 1.3, the only difference being that 1.3 includes
225 a content-length in the response, and this does not.
228 *) APR read/write functions and bucket read functions now operate
229 on unsigned integers, instead of signed ones. It doesn't make
230 any sense to use signed ints, because we return the error codes,
231 so if we have an error we should report 0 bytes read or written.
234 *) Always compute the content length, whether it is sent or not.
235 The reason for this, is that it allows us to correctly report
236 the bytes_sent when logging the request. This also simplifies
237 content-length filter a bit, and fixes the actual byte-reporing
238 code in mod_log_config.c
241 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
242 it says, because it was only used by EOS and FLUSH buckets. Since
243 neither of those are required at the end of a brigade, this was
244 really signifying FLUSH_THE_DATA, but that can be determined better
245 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
246 buckets now return a length of 0, which is actually the amount of data
247 read, so they make more sense.
250 *) Allow the core_output_filter to save some data past the end of a
251 request. If we get an EOS bucket, we only send the data if it
252 makes sense to send it. This allows us to pipeline request
253 responses. As a part of this, we also need to allocate mmap
254 buckets out of the connection pool, not the request pool. This
255 allows the mmap to outlive the request.
258 *) Make blocking and non-blocking bucket reads work correctly for
259 sockets and pipes. These are the only bucket types that should
260 have non-blocking reads, because the other bucket types should
261 ALWAYS be able to return something immediately.
264 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
265 server, but use Ctrl+Break to initiate a graceful restart
266 instead of duplicating behavior. [John Sterling]
268 *) Patch mod_autoindex to set the Last-Modified header based on
269 the directory's mtime, and add the ETag header. [William Rowe]
271 *) Merge the 1.3 patch to add support for logging query string in
272 such a way that "%m %U%q %H" is the same as "%r".
275 *) Port three log methods from mod_log_config 1.3 to 2.0:
276 CLF compliant '-' byte count, method and protocol.
279 *) Add a new LogFormat directive, %c, that will log connection
280 status at the end of the response as follows:
281 'X' - connection aborted before the response completed.
282 '+' - connection may be kept-alive by the server.
283 '-' - connection will be closed by the server.
286 *) Expand APR for WinNT to fully accept and return utf-8 encoded
287 Unicode file names and paths for Win32, and tag the Content-Type
288 from mod_autoindex to reflect that charset if the the feature
289 macro APR_HAS_UNICODE_FS is true. [William Rowe]
291 *) Compute the content length (and add appropriate header field) for
292 the response when no content length is available and we can't use
293 chunked encoding. [Jeff Trawick]
295 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
296 so that content input filters get dechunked data when using
297 the default handler. Also removed REQUEST_CHUNKED_PASS.
300 *) Add mod_ext_filter as an experimental module. This module allows
301 the administrator to use external programs as filters. Currently,
302 only filtering of output is supported. [Jeff Trawick]
304 *) Most Apache functions work on EBCDIC machines again, as protocol
305 data is now translated (again). [Jeff Trawick]
307 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
308 the EBCDIC support. They are noops on ASCII machines, so this
309 type of translation doesn't have to be surrounded by #ifdef
310 CHARSET_EBCDIC. [Jeff Trawick]
312 *) Fix mod_include. tag commands work again, and the server will
313 send the FAQ again. This also allows mod_include to set aside
314 buckets that include partial buckets.
315 [Ryan Bloom and David Reid]
317 *) Add suexec support back. [Manoj Kasichainula]
319 *) Lingering close now uses the socket directly instead of using
320 BUFF. This has been tested, but since all we can tell is that it
321 doesn't fail, this needs to be really hacked on.
324 *) Allow filters to modify headers and have those headers be sent to
325 the client. The idea is that we have an http_header filter that
326 actually sends the headers to the network. This removes the need
327 for the BUFF to send headers.
330 *) Charset translation: mod_charset_lite handles translation of
331 request bodies. Get rid of the xlate version of ap_md5_digest()
332 since we don't compute digests of filtered (e.g., translated)
333 response bodies this way anymore. (Note that we don't do it at
334 all at the present; somebody needs to write a filter to do so.)
337 *) Input filters and ap_get_brigade() now have a input mode parameter
338 (blocking, non-blocking, peek) instead of a length parameter.
341 *) Update the mime.types file to the registered media types as
342 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
345 *) Namespace protect some macros declared in ap_config.h
348 *) Support HTTP header line folding with input filtering.
351 *) Mod_include works again. This should still be re-written, but at
352 least now we can serve an SHTML page again.
355 *) Begin to remove BUFF from the core. Currently, we keep a pointer
356 to both the BUFF and the socket in the conn_rec. Functions that
357 want to use the BUFF can, functions that want to use the socket,
358 can. They point to the same place.
361 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
362 [Tomas "Ögren" <stric@ing.umu.se>]
364 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
365 associated pool goes away. (APR pipes on OS/2 were already had this
366 logic.) This resolvs a fatal file descriptor leak with CGIs.
369 *) The final line of the config file was not being read if there was
370 no \n at the end of it. This was caused by apr_fgets returning
371 APR_EOF even though we had read valid data. This is solved by
372 making cfg_getline check the buff that was returned from apr_fgets.
373 If apr_fgets return APR_EOF, but there was data in the buf, then we
374 return the buf, otherwise we return NULL.
377 *) Piped logs work again in the 2.0 series.
380 *) Restore functionality broken by the mod_rewrite security fix:
381 rewrite map lookup keys and default values are now expanded
382 so that the lookup can depend on the requested URI etc.
383 PR #6671 [Tony Finch]
385 *) Tighten up the syntax checking of Host: headers to fix a
386 security bug in some mass virtual hosting configurations
387 that can allow a remote attacker to retrieve some files
388 on the system that should be inaccessible. [Tony Finch]
390 *) Add a pool bucket type. This bucket is used for data allocated out
391 of a pool. If the pool is cleaned before the bucket is destroyed, then
392 the data is converted to a heap bucket, allowing it to survive the
396 *) Add a flush bucket. This allows modules to signal that the filters
397 should all flush whatever data they currently have. There is no way
398 to actually force them to do this, so if a filter ignores this bucket,
399 that's life, but at least we can try with this.
402 *) Add an output filter for sub-requests. This filter just strips the
403 EOS bucket so that we don't confuse the main request's core output
404 filter by sending multiple EOS buckets. This change also makes sub
405 requests start to send EOS buckets when they are finished.
408 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
409 makes ap_bucket_destroy a return void, which is okay because it
410 used to always return APR_SUCCESS, and nobody ever checked its
412 [Cliff Woolley <cliffwoolley@yahoo.com>]
414 *) Remove the index into the bucket-type table from the buckets
415 structure. This has now been replaced with a pointer to the
416 bucket_type. Also add some macros to test the bucket-type.
419 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
420 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
421 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
422 All _VAR_ flavors changes to _DATA to be absolutely clear.
425 *) Add support for /, //, //servername and //server/sharename
426 parsing of <Directory> blocks under Win32 and OS2.
427 [Tim Costello, William Rowe, Brian Harvard]
429 *) Remove the function pointers from the ap_bucket type. They have been
430 replaced with a global table. Modules are allowed to register bucket
431 types and use then use those buckets.
434 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
435 once we finish writing the request body to the cgi child process;
436 otherwise, the client doesn't hit EOF on stdin. Small request bodies
437 worked without this change (for reasons I don't understand), but large
438 ones didn't. [Jeff Trawick]
440 *) Remove file bucket specific information from the ap_bucket type.
441 This has been moved to a file_bucket specific type that hangs off
442 the data pointer in the ap_bucket type.
445 *) Input filtering now has a third argument. This is the amount of data
446 to read from lower filters. This argument can be -1, 0, or a positive
447 number. -1 means give me all the data you have, I'll deal with it and
448 let you know if I need more. 0 means give me one line and one line
449 only. A positive number means I want no more than this much data.
451 Currently, only 0 and a positive number are implemented. This allows
452 us to remove the remaining field from the conn_rec structure, which
456 *) Big cleanup of the input filtering. The goal is that http_filter
457 understands two conditions, headers and body. It knows where it is
458 based on c->remaining. If c->remaining is 0, then we are in headers,
459 and http_filter returns a line at a time. If it is not 0, then we are
460 in body, and http_filter returns raw data, but only up to c->remaining
461 bytes. It can return less, but never more.
462 [Greg Ames, Ryan Bloom, Jeff Trawick]
464 *) mod_cgi: Write all of the request body to the child, not just what
465 the kernel would accept on the first write. [Jeff Trawick]
467 *) Back out the change that moved the brigade from the core_output_filters
468 ctx to the conn_rec. Since all requests over a given connection
469 go through the same core_output_filter, the ctx pointer has the
473 *) Fix another bug in the send_the_file() read/write loop. A partial
474 send by apr_send would cause unsent data in the read buffer to
475 get clobbered. Complete making send_the_file handle partial
476 writes to the network.
479 *) Fix a couple of type fixes to allow compilation on AIX again
480 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
482 *) Fix bug in send_the_file() which causes offset to be ignored
483 if there are no headers to send.
486 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
487 filter. Useful for supporting Windows 9* with a binary
488 compiled on Windows NT.
491 Changes with Apache 2.0a7
493 *) Reimplement core_output_filter to buffer/save bucket brigades
494 across multiple calls to the core_filter. The brigade will be
495 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
496 thresholds are hit or the EOS bucket is received.
499 *) Create experimental filter (buffer_filter) that coalesces bytes
500 into one large buffer before invoking the next filter in the
501 chain. This filter is particularly useful with the current
502 implementation of mod_autoindex when it inserted above the
503 chunk_filter. mod_autoindex generates a lot of brigades that
504 containing buckets holding just a few bytes each. The
505 buffer_filter coalesces these buckets into a single large bucket.
508 *) Add apr_sendfile() support into the core_output_filter.
511 *) Add apr_sendv() support into the core_output_filter.
514 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
515 [Mike Abbott <mja@sgi.com>]
517 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
518 make much sense, because Apache uses buckets instead of BUFFs now.
521 *) send_the_file now falls back to a read/write loop on platforms that
522 do not have sendfile.
523 [Ryan Bloom and Brian Havard]
525 *) Install apachectl correctly, and substitute the proper values so
526 that it works again. [Ryan Bloom]
528 *) Better(??) handle platforms that lack sendfile().
531 *) APR now has UUID generation/formatting/parsing support.
534 *) Begin the http_filter. This is an input filter that understands
535 the absolute basic amount required to parse an HTTP Request. The
536 goal is to be able to split headers from request body before passing
537 the data back to the other filters.
540 *) Bring forward from 1.3.13 the config directory implementation
543 *) install apxs if it is created
546 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
547 conversions. [William Rowe]
549 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
550 ap_add_output_filter(). [Jeff Trawick]
552 *) Multiple build and configuration fixes
555 -add datadir and localstatedir substitutions
557 -fix logfilename misspelling
558 -fix evaluation of installation dir variables and
559 -replace $foobar by $(foobar) to be usefull in the makefile
563 -add rules for cross-compiling in rules.mk. Okay, rule to check for
564 $CC_FOR_BUILD is still missing
565 -use CHECK_TOOL instead of CHECK_PROG for ranlib
566 -add missing "AR=@AR@" to severaly Makefile.in's
567 -cache result for "struct rlimit"
568 -compile all helper programs with native and cross compiler
569 and use the native version to generate header file
570 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
572 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
574 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
576 *) Fix a bug where a client which only sends \n to delimit header
577 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
578 message. Start working on ebcdic co-existance with input
580 [William Rowe, Greg Ames]
582 *) If mod_so is enabled in the server always create libexec, even
583 if there are no modules installed in this directory. This is a
584 requirement for APXS to work correctly.
587 *) Connection oriented output filters are now stored in the
588 conn_rec instead of the request_rec. This allows us to add the
589 output filter in the pre-connection phase instead of the
590 post_read_request phase, which keeps us from trying to write an
591 error page before we have a filter to write to the network.
592 [Ryan Bloom, Jeff Trawick, and Greg Ames]
594 *) Cleaning up an mmap bucket no longer deletes the mmap. An
595 mmap can be used across multiple buckets (default_handler with
596 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
597 the mmap itself can't be associated with the bucket.
600 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
603 *) Radical surgery to improve mod_isapi support under Win32.
604 Includes a number of newer ServerSupportFunction calls, support
605 for ReadClient (in order to retrieve POSTs greater than 48KB),
606 and general bug fixes to more reliably load ISAPI .dll's and
607 prevent leaking handle resources. Note: There are still
608 discrepancies between IIS's and Apache's ServerVariables, and
609 async calls are still not supported. Additional warnings are
610 logged to facilitate debugging of unsupported ISAPI calls.
613 *) Add input filtering to Apache. The basic idea for the input
614 filters is the same as the ideas for output filters. The biggest
615 difference is that instead of calling ap_pass_brigade, ap_get_brigade
616 should be called, and the order of execution for the filter itself is
617 different. When writing an output filter, a brigade is passed in,
618 and filters operate directly on that brigade, when done, they call
619 ap_pass_brigade. Input filters are the exact opposite. Because input
620 is not a push operation, filters first call ap_get_brigade. When this
621 function returns, the input filter will be left with a valid brigade.
622 The input filter should then operate on the brigade, and return.
625 *) Fix building on BSD/OS using its native make. The build system
626 falls back to the BSD .include directive on that host platform.
629 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
630 SHA1 and plaintext password encodings. Make feature tests a
631 bit more flexible. [William Rowe]
633 *) Charset translation: mod_charset_lite handles output content
634 translation in a filter. mod_charset_lite no longer ignores
635 subrequests. A bunch of cruft related to BUFF's support for
636 translating request and response bodies was removed.
639 *) Move the addition of the CORE filter to the post_read_request
640 hook in http_core.c. This removes the need to add the filter in
641 multiple places and allows for an SSL module to be added much
642 simpler. [Ryan Bloom]
644 *) Fix a security problem that affects certain configurations of
645 mod_rewrite. If the result of a RewriteRule is a filename that
646 contains expansion specifiers, especially regexp backreferences
647 $0..$9 and %0..%9, then it may be possible for an attacker to
648 access any file on the web server. [Tony Finch]
650 *) Fix a bug where errors that are detected during early request parsing
651 don't produce visible HTTP error messages at the browser, because
652 the core_filter wasn't present. [Greg Ames]
654 *) Provide apr_socklen_t as a portability aid.
655 [Victor J. Orlikowski]
657 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
658 as well as a comment arg to the add, adduser and update cmds.
659 update allows the user to clear or preserve pw/groups/comment.
660 Fixed a bug in dbmmanage that prevented the check option from
661 parsing a password followed by :group... text. Corrected the
662 seed calcualation for Win32 systems, and added -lsdbm support.
665 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
668 *) Avoid a segfault when parsing .htaccess files. An
669 uninitialized tree pointer was passed to ap_build_config().
672 *) Change the way that inet_addr & inet_network are checked for
673 in APR's configure process to allow BeOS BONE to correctly
674 find them. With this change BeOS BONE now builds from source
675 with no problems. [David Reid]
677 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
678 the end of the parameters to execve() was stored in the wrong
679 location, overlaying the storage beyond the newargs[] array and
680 also passing uninitialized storage to execve(), which would
681 sometimes fail with EFAULT. [Jeff Trawick]
683 *) Fix a bug parsing configuration file containers. With a sequence
684 like this in the config file
686 <IfModule mod_kilroy.c>
689 <IfModule mod_lovejoy.c>
694 the second container would be terminated at the blank line due to
695 sediment in the buffer from reading the prior </IfModule> and an
696 error message would be generated for the real </IfModule> for the
697 second container. Also due to this problem, any two characters
698 could be used for "</" in the close of a container.
701 *) ap_add_filter prototype changed to remove the ctx pointer. The
702 pointer still remains in the filter structure, but it can not be
703 a part of the ap_add_filter prototype. The reason is that when
704 the core uses AddFilter to add a filter to the stack it doesn't
705 know how to allocate the ctx pointer, or even how much memory should
706 be allocated. The filters will have to be responsible for allocating
707 the ctx memory when they need it.
710 *) Add an AddFilter directive. This directive takes a list of filters
711 that should be activated for the requested resource.
714 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
715 some other platforms). [Jeff Trawick]
717 *) Modify mod_include to be a filter. Currently, it has only been tested
718 on actual files, but it should work for CGI scripts too.
721 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
722 writes. apr_flush() for Unix: handle interrupted writes.
725 *) NameVirtualHost can now take "*" as an argument instead of
726 an IP address. This allows you to create a purely name-based
727 virtual hosting server that does not have any IP addresses in
728 the configuration file and which ignores the local address
729 of any connections. PR #5595, PR #4455 [Tony Finch]
731 *) Fix some compile warnings in mod_mmap_static.c
732 [Mike Abbott <mja@sgi.com>]
734 *) Fix chunking problem with CGI scripts. The general problem was that
735 the CGI modules were adding an EOS bucket and then the core added an
736 EOS bucket. The chunking filter finalizes the chunked response when it
737 encounters an EOS bucket. Because two EOS buckets were sent, we
738 finalized the response twice. The fix is to make sure we only send one
739 EOS, by utilizing a flag in the request_rec.
742 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
743 and Win32. Previously, the first read from an apr_file_t set up via
744 apr_put_os_file() would return a '\0'. [Jeff Trawick]
746 *) Mod_cgid now creates a single element bucket brigade, with a pipe
747 bucket, instead of using BUFF's and ap_r*.
750 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
751 [Mike Abbott <mja@sgi.com>]
753 *) Remove ap_bopenf from buff code. This required modifying the file_cache
754 code to use APR file's directly instead of going through BUFFs.
757 *) Fix compile break on some platforms for mod_mime_magic.c
758 [John K. Sterling <sterling@covalent.net>]
760 *) Fix merging of AddDefaultCharset directive.
761 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
763 *) Minor revamp of the rlimit sections of code. We now test
764 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
765 is now "available" even if the platform doesn't support
766 the rlimit family (it's just a noop though). [Jim Jagielski]
768 *) Migrate the pre-selection of which MPM to use for specific
769 platforms to hints.m4, which contains (or should contain)
770 all platform specific "hints". [Jim Jagielski]
772 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
775 *) Add tables with non-string/binary values to APR.
778 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
781 *) Update PCRE to version 3.2. [Ryan Bloom]
783 *) Change the way buckets' destroy functions are called so that
784 they can be more directly used when changing the type of a
785 bucket in place. [Tony Finch]
787 *) Add generic support for reference-counting the resources used by
788 buckets, and alter the HEAP and MMAP buckets to use it. Change
789 the way buckets are initialised to support changing the type of
790 buckets in place, and use it when setting aside TRANSIENT buckets.
791 Change the implementation of TRANSIENT buckets so that it can be
792 mostly shared with IMMORTAL buckets, which are now implemented.
795 Changes with Apache 2.0a6
797 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
799 *) Add a chunking filter to Apache. This brings us one step closer
800 to removing BUFF. [Ryan Bloom]
802 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
803 added to the stack is the last filter to be called. [Ryan Bloom]
805 *) Apache 2.0 has been completely documented using Scandoc. The
806 docs can be generated by running 'make docs'. [Ryan Bloom]
808 *) Add filtered I/O to Apache. This is based on bucket brigades,
809 Currently the buckets still use BUFF under the covers, but that
810 should change quickly. The only currently written filter is the
811 core filter which just calls ap_bwrite. [The Apache Group]
813 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
814 built with thread support. [Jeff Trawick]
816 *) Abort configuration if --with-layout was specified and there's
817 no layout definition file. [Ken Coar]
819 *) Add support for '--with-port=n' option to configure. [Ken Coar]
821 *) Add support for extension methods for the Allow response header
822 field, and an API routine for accessing r->allowed and the
823 list of extension methods in a unified manner. [Ken Coar]
825 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
826 [Rob Simonson <simo@us.ibm.com>]
828 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
829 APACHE_XLATE builds. [Jeff Trawick]
831 *) A configuration file parsing problem was fixed. When the
832 configuration file started with an IfModule/IfDefine container,
833 only the last statement in the container would be retained.
836 Changes with Apache 2.0a5
838 *) Perchild is serving pages after passing them to different child
839 processes. There are still a lot of bugs, but this does work. I
840 have made requests against the same installation of Apache, and had
841 different servers use different user IDs to serve the responses.
842 This change moves to using socketpair instead of an AF_UNIX socket.
845 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
846 It can't seem to pass between child processes yet, but I think we
847 are closer now than before. This moves us back to using Unix
848 Domain Sockets. [Ryan Bloom]
850 *) libapr functions and types renamed with apr_ prefix.
851 #include "apr_compat.h" for 1.3.x backwards compat
854 *) Fix problems with APR sockaddr handling on Win32. It didn't always
855 return the right information on the local socket address.
856 [Gregory Nicholls <gnicholls@level8.com>]
858 *) ap_recv() on Win32: Set bytes-read to 0 on error.
859 [Gregory Nicholls <gnicholls@level8.com>]
861 *) Add an option to not detach from the controlling terminal without
862 going into single process mode. This allows for much easier
863 debugging of the process startup code. [Ryan Bloom]
865 *) ab: don't use perror() to report the failure of an APR function.
868 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
869 scoreboard on graceful restarts.
872 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
873 An invalid ap_proc_t was passed to ap_create_process().
876 *) Allow modules to register filters. Those filters are still
877 never called, but this is a step in the right direction.
878 [Ryan Bloom and Greg Stein]
880 *) Register the mod_cgid daemon process for cleanup so that it is
881 killed at termination if it does not die when the parent gets
882 SIGTERM. This change is to fix occasional problems where the
883 process stays around. Bugs in similar logic in mod_rewrite and
884 mod_include were also fixed. [Jeff Trawick]
886 *) Fix a bug in the time handling. Basically, we were imploding a time
887 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
888 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
889 uses those two fields to adjust the time value. Because of the HTTP
890 spec, both of those values can be zero'ed out safely. This fixes
891 the bug correctly. [Ryan Bloom]
893 *) Fix a couple of place in the Windows code where the wrong error
894 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
896 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
898 *) Added the APR_EOL_STR macro for platform dependent differences in
899 logfiles and other raw text (such as all APR files). Fixes logfiles
900 not terminated with cr/lf sequences in Win32. [William Rowe]
902 *) Move all strings functions in APR to src/lib/apr/strings and create
903 apr_strings.h for the prototypes. [Ryan Bloom]
905 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
906 to repeat the syscall until we stop getting EINTR. I noticed a
907 related problem at termination (SIGTERM) on FreeBSD when using
908 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
909 implementation work properly with child init. Previously, ap_lock()
910 was essentially a no-op because all children were using different
911 locks and thus nobody ever blocked. [Jeff Trawick]
913 *) The htdocs/ tree has been moved out of the CVS source tree into
914 a separate area for easier development. This has NO EFFECT on
915 end-users or Apache installations. [Ken Coar]
917 *) Integrate the mod_dav module for WebDAV protocol handling. This
918 adds the dav and dav_fs modules, the SDBM library, and additional
919 XML handling utilities. [Greg Stein]
921 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
924 *) Update the lib/expat-lite/ library (bring forward changes from
925 the Apache 1.3 repository). [Greg Stein]
927 *) If sizeof(long long) == sizeof(long), then prefer long in APR
928 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
930 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
931 machines where sendfile is detected, but nobody has written ap_sendfile.
932 [Dave Hill <ddhill@zk3.dec.com>]
934 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
936 *) ab would start up more connections than needed, then quit when the
937 desired number were finished. Also fixed a logic error involving
938 ab keepalives. [Victor J. Orlikowski]
940 *) WinNT: Implement non-blocking pipes with timeouts to communicate
941 with CGIs. Apache 2.0a4 had non-blocking pipes but without
942 timeouts (i.e, if a timeout was specified, the pipe reverted to
943 a full blocking pipe). Now the behaviour is more in line with
944 Unix non-blocking pipes.
947 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
948 cache open file handles along with accept socket reuse enables
949 Apache 2.0 to serve non-keepalive requests for static files at
950 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
951 and Apache 2.0 will serve almost 1200 rps on my system).
954 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
955 supports two config directives, mmapfile (same behavious as
956 mod_mmap_static) and cachefile. Use the cachefile directive
957 to cache open file handles. This directive only works on systems
958 that have implemented the ap_sendfile API. cachefile works today
959 on Windows NT, but has not been tested on any flavors of Unix.
962 *) Cleanup the configuration. With the last few changes the
963 configuration process automatically:
964 inherits information about how to build from APR. Allowing
965 APR to inform Apache that it should or should not use -ldl
967 Detects which mod_cgi should be used mod_cgi or mod_cgid,
968 based on the threading model
970 Apache calls APR's configure process before finishing it's
971 configuration processing, allowing for more information flow
976 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
977 with non-zero argument makes the socket non-blocking. BeOS and
978 OS/2 already worked this way. [Jeff Trawick]
980 *) ap_close() now calls ap_flush() for buffered files, so write
981 operations work a whole lot better on buffered files.
984 *) Fix error messages issued from MPMs which explain where to change
985 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
988 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
989 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
990 now the way that the blocking state of a pipe is manipulated.
991 ap_block_pipe() is gone. [Jeff Trawick]
993 *) Correct the problem where the only local host name that the IP stack
994 can discover are 'undotted' private names. If no fully qualified
995 domain name can be identified, the default ServerName will be set to
996 the machine's IP address string. A warning is always provided if the
997 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
999 *) Repair problems with config file processing which caused segfault
1000 at init when virtual hosts were defined and which caused ServerName to
1001 be ignored when there was no valid DNS setup. [Jeff Trawick]
1003 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
1005 *) Add ap_sendfile implementation for AIX
1006 [Victor J. Orlikowski]
1008 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
1009 apr_network_io.h, and apr_thread_proc.h.
1010 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
1012 *) Bring the allocation and pool debugging code back into a working
1013 state. This will need to be tested as so far it's only been used on
1016 *) Change configuration command setup to be properly typesafe when in
1017 maintainer mode. Note that this requires a compiler that can initialise
1018 unions. [Ben Laurie]
1020 *) Turn on buffering for config file reads. Part of this was to
1021 repair buffered I/O support in Unix and implement buffered
1022 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
1024 *) Win32: Fix problem where UTC offset was not being set correctly
1025 in the access log. Problem reported on news group by Jerry Baker.
1028 *) Fix segfault when reporting this type of syntax error:
1029 "</container> without matching <container> section", where
1030 container is VirtualHost or Directory or whatever.
1033 *) Prevent the source code for CGIs from being revealed when using
1034 mod_vhost_alias and the CGI directory is under the document root
1035 and a user makes a request like http://www.example.com//cgi-bin/cgi
1036 as reported in <news:960999105.344321@ernani.logica.co.uk>
1039 *) Add support for the new Beos NetwOrking Environment (BONE)
1042 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
1043 final input char is incomplete; ap_bwrite_xlate() now handles
1044 incomplete final input chars. [Jeff Trawick]
1046 *) Yet another update to saferead/halfduplex stuff -- need to ensure
1047 that a bhalfduplex call occurs before logging or else DNS and
1048 such can delay the last packet of the response. [Dean Gaudet]
1050 *) Some syscall reduction in APR on unix -- don't seek when setting
1051 up an mmap; and don't fcntl() more than once per socket.
1054 *) When mod_cgid is started as root, the cgi daemon now switches
1055 to the configured User/Group (like other httpd processes)
1056 instead of continuing as root. [Jeff Trawick]
1058 *) The prefork MPM now uses an APR lock for the accept() mutex.
1059 It has not been getting a lock at all recently. httpd -V now
1060 displays APR's selection of the lock mechanism instead of the
1061 symbols previously respected by prefork. [Jeff Trawick]
1063 *) Change the mmap() feature test to check only for existence.
1064 The previous check required features not used by Apache.
1067 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
1068 sometimes mangled. The len parm to accept() was not
1069 initialized, leading sometimes to an endless loop of failed
1070 accept() calls on OS/390 and anywhere else that failed the call
1071 if the len was negative. Use <sys/un.h> for struct sockaddr_un
1072 instead of declaring it ourselves to fix a compilation problem
1073 on Solaris. [Jeff Trawick]
1075 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
1077 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
1079 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
1081 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
1082 initialization if ALLOC_DEBUG is defined; no known symptom
1083 otherwise. [Jeff Trawick]
1085 *) Fix typo in configure script when checking for mod_so. bash
1086 doesn't seem to have a problem but /bin/sh on Solaris does.
1087 Symptom: "./configure: test: unknown operator =="
1090 *) Rebind the Win32 NT and 9x services control into the MPM.
1091 All console, WinNT SCM and Win9x pseudo-service control code is
1092 now wrapped within the WinNT MPM.
1095 *) Make a copy of getenv("PATH") before storing for later use. Some
1096 getenv() implementations use the same storage for successive calls.
1097 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
1099 *) Server Tokens work in 2.0 again. This also propogates the change
1100 to allow just the product name in the server string using
1104 Changes with Apache 2.0a4
1106 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
1107 won't need to call it. [Greg Ames, Jeff Trawick]
1109 *) Move pre_config hook call to between configuration read and config
1110 tree walk. This allows all modules to implement pre_config hooks
1111 and know that they will be called at an appropriate time.
1114 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
1117 *) Add pre-config hooks back to all modules.
1120 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
1121 ContentDigest enabled and we can't/don't mmap the file.
1124 *) We now report the correct line number for syntax errors in config
1125 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
1127 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
1128 related bugs, and changed shmem/locking to use apr API. Shared-mem
1129 is currently disabled, however, because of problems with graceful
1130 restarts. [Ronald Tschalär]
1132 *) Fix corruption of IFS variable in --with-module= handling.
1133 Depending on the user's shell or customization thereof, there
1134 would be errors generating ap_config_auto.h later in the configure
1135 procedure. [Jeff Trawick]
1137 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
1138 isn't used (as in 1.3), except that on Unix it is now logged via
1139 ap_log_rerror() instead of by the child having STDERR_FILENO refer
1140 to the error log. [Greg Ames, Jeff Trawick]
1142 *) Add '-D' argument processing for run time configuration defines.
1145 *) Organize http_main.c as independent code, such that no code or
1146 global data is exported from it. WIN32 will dynamically link it
1147 to the server core, so this will prevent mutual dependency.
1150 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
1151 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
1154 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
1155 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
1157 *) Add mod_charset_lite for configuring character set translation.
1160 *) Add '-n' option to htpasswd to make it print its user:pw record
1161 on stdout rather than having to frob a text file. [Ken Coar]
1163 *) Fix saferead. Basically, we flush the output buffer if a read on the
1167 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
1168 a conversion is single-byte only. [Jeff Trawick]
1170 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
1171 the BeOS 5.0 documentation says that shutdown doesn't work yet.
1174 *) Fix some minor errors where pid was being manipulated as an int
1175 instead of the portable pid_t. [Roy Fielding]
1177 *) Fix some error log prints that were printing the pointer to a
1178 structure rather than the pid within the structure.
1179 [Jeff Trawick, Roy Fielding]
1181 *) ab: Fix a command-line processing bug; track bad headers in
1182 err_response; support reading headers up to 2K.
1183 [Ask Bjoern Hansen <ask@valueclick.com>]
1185 *) Fix ap_resolve_env() so that it handles new function added in a prior
1186 alpha (see "Added the capability to do ${ENVVAR} constructs in the
1187 config file.") as well as the constructs used by mod_rewrite.
1188 [Paul Reder <rederpj@raleigh.ibm.com>]
1190 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
1192 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
1193 APR to perform translation, instead of accessing the hard-coded tables
1194 in 1.3's ebcdic.c. [Jeff Trawick]
1196 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
1199 *) Add the ability to hook into the config file reading phase. Basically
1200 if a directive is specified EXEC_ON_READ, then when that directive is
1201 read from the config file, the assocaited function is executed. This
1202 should only be used for those directives that must muck with HOW the
1203 server INTERPRETS the config. This should not be used for directives
1204 that re-order or replace items in the config tree. Those changes should
1205 be made in the pre-config step.
1208 *) Add mod_example to the build system.
1211 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
1212 byte character sets. [Jeff Trawick]
1214 *) Pick up various EBCDIC fixes from 1.3 (from Martin
1215 Kraemer and Oliver Reh originally according to the change log).
1218 *) Fix a couple of problems in RFC1413 support (controlled by the
1219 IdentityCheck directive). Apache did not build the request string
1220 properly and more importantly Apache would loop forever if the
1221 would-be ident server dropped the connection before sending a
1222 properly terminated response. [Jeff Trawick]
1224 *) apxs works in 2.0.
1227 *) Reliable piped logs work in 2.0.
1230 *) Introduce a hash table implementation into APR to be used for
1231 replacing tables and other random data structures in Apache.
1234 *) Add some more error reporting to htpasswd in the case of problems
1235 generating or accessing the temporary file. Also, pass in a
1236 buffer if the implementation knows how to use it (i.e., if L_tmpnam
1237 is defined). [Ken Coar]
1239 *) Configure creates config.nice now containing your configure
1240 options. Syntax: ./config.nice [--more-options]
1243 *) Fix various return code problems in APR on Win32. For most of
1244 these, APR was returning APR_EEXIST instead of GetLastError()/
1245 WSAGetLastError(). [Jeff Trawick]
1247 *) Make piped logs work again in version 2.0
1250 *) Add VPATH support to UNIX build system of Apache and APR.
1253 *) Fix ap_tokenize_to_argv to respect the const arguments that are
1257 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
1258 Patch submitted to author.
1261 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
1262 /sbin in PATH on FreeBSD (all submitted to rse previously)
1265 *) Fix building Pthread-based MPMs on OpenBSD
1266 [Sascha Schumann] PR#26
1268 *) Fix ap_readdir() problem on systems where d_name[] field in
1269 struct dirent is declared with only one byte. (This problem only
1270 affected multithreaded builds.) This caused a segfault during
1271 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
1272 least). [Jeff Trawick]
1274 *) Fix some make-portability problems on at least Tru64, Irix
1276 [Sascha Schumann] PR#18, PR#39
1278 *) Add ap_sigwait() to support old-style sigwait() on systems
1279 like OS/390 and UnixWare.
1282 *) Add POSIX-thread flags for more platforms.
1285 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
1286 (on Unix, at least) to handle resolver errors. Fix a bug in
1287 the definition of APR_ENOMEM so that ap_strerror() can spit
1288 out the correct error message for it.
1291 Changes with Apache 2.0a3
1293 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
1296 *) API: *HOOK* macros now have an AP_ prefix
1299 *) Win32: Eliminate redundant calls to initialize winsock.
1300 [Tim Costello <timcostello@ozemail.com.au>]
1302 *) Fix bugs initializing ungetchar for pipes.
1303 [Chia-liang Kao <clkao@CirX.ORG>]
1305 *) The ab program in the src/support directory is now portable using
1309 *) Support directory is being compiled when the server is built
1312 *) The configure option --with-program-name has been added to allow
1313 developers to rename the executable at configure time. This also
1314 changes the name of the config files to match the executable's name.
1317 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
1318 containing version numbers. [Martin Pool]
1320 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
1321 Unix; access_log and error_log now created with these perms; non-
1322 Unix is unaffected [Jeff Trawick]
1324 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
1325 Replaced more magic numbers with MD5_DIGESTSIZE.
1326 [William Rowe, Roy Fielding]
1328 *) Win32: Get mod_auth_digest compiling and added to the Windows
1329 build environment. Not tested and I'd be suprised if it
1330 actually works. [Bill Stoddard]
1332 *) Revamp the Win32 make environment. Makefiles have been removed and
1333 Apache.dsw created to bring together all the pieces. Create new file
1334 os/win32/BaseAddr.ref to define module base addresses (to prevent
1335 dll relocation at start-up).
1336 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
1338 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
1339 of the \015, \012, and \015\012 constants with macros.
1340 [Greg Ames <gregames@us.ibm.com>]
1342 *) Add ap_xlate_open() et al for translation of text between different
1343 character sets. The initial implementation requires iconv().
1346 *) More FAQs and answers from comp.infosystems.www.servers.unix.
1347 [Joshua Slive <slive@finance.commerce.ubc.ca>]
1349 *) CGI output is being timed out now.
1352 *) Fix the problem with dieing quietly. dupfile now takes a pool which
1353 is used by the new apr file. There is no reason to create a new file
1354 with the same lifetime as the original file.
1357 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
1358 module base addresses. This will help shooting seg faults
1359 in the field. [William Rowe <wrowe@lnd.com>]
1361 *) Update Apache on Windows documentation. Add new document
1362 describing how to compile Apache on Windows.
1363 [William Rowe <wrowe@lnd.com>]
1365 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
1366 microseconds instead of seconds. Some storage leaks and other
1367 minor bugs in related code were fixed. [Jeff Trawick]
1369 *) Win32: First cut at getting mod_isapi working under 2.0
1370 [William Rowe <wrowe@lnd.com>]
1372 *) First stab at getting mod_auth_digest working under 2.0
1373 quick change summary:
1374 - moved the random byte generation (ap_generate_random_bytes) into APR
1375 - now uses ap_time_t
1376 - compiles and runs on linux
1378 [Brian Martin <bmartin@penguincomputing.com>]
1380 *) Win32: Move the space stripping of physical service names
1381 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
1382 unresolved symbol. Add dependency checking to the
1383 CreateService call to ensure TCPIP and AFP (winsock) is started
1385 [William Rowe <wrowe@lnd.com>]
1387 *) Win32: Add code to perform latebinding on functions that may
1388 not exist on all levels of Windows where Apache runs. This
1389 is needed to allow Apache to start-up on Win95/98. All calls
1390 to non portable functions should be protected with
1391 ap_oslevel checks to prevent runtime segfaults.
1392 [William Rowe <wrowe@lnd.com>]
1394 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
1396 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
1398 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
1399 This addresses PR 1623. Still need to address timing out runaway
1400 CGI scripts. [Bill Stoddard]
1402 *) Win32: Make ap_stat Windows 95/98 friendly
1403 [William Rowe <wrowe@lnd.com>]
1405 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
1406 always fail. Need to initialise the dwOSVersionInfoSize member of the
1407 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
1410 The patch also enhances ap_get_oslevel (and the associated enum) to
1411 handle selected service packs for NT4, and adds recognition for
1412 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
1413 we can use ReadFileScatter and WriteFileGather in readwrite.c.
1414 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
1416 *) Get mod_rewrite building and running, and mod_status building for Win NT
1417 [Allan Edwards <ake@raleigh.ibm.com>]
1419 *) Patch to port mod_auth_db to the 2.0 api and also to support
1420 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
1421 2.7.7. It should work with version 1 as well but I haven't tested it.
1422 [Brian Martin <bmartin@penguincomputing.com>]
1424 *) Get APR DSO code working under Windows. Includes cross platform
1426 [Tim.Costello@BTFinancialgroup.com]
1428 *) Fix some of the Windows APR time functions.
1431 *) FAQ changes related to tidying up historical documents on the web site.
1432 [Joshua Slive <slive@finance.commerce.ubc.ca>]
1434 *) Move Windows DSO code into APR.
1437 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
1438 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
1439 at build time. At this point, the server will not compile on Windows because
1440 of the recent DSO commits. Fixing those next.
1441 [Bill Rowe & Bill Stoddard]
1443 *) Added error checking for file I/O APR routines.
1444 [Jon Travis <jtravis@covalent.net>]
1446 *) APR: Don't use the values of resolver error codes for the
1447 corresponding APR error codes. On Unix and Win32, return the
1448 proper APR error code after a resolver error. [Jeff Trawick]
1450 Changes with Apache 2.0a2
1452 *) Renamed the executable back to httpd on all platforms other
1456 *) Allow BeOS to survive restarts, log properly and a few
1457 small things it had problems with due to the way it setup
1458 users and groups. [David Reid]
1460 *) Get mod_rewrite working with APR locks
1461 [Paul Reder <rederpj@raleigh.ibm.com>]
1463 *) Actually remove the sempahore when the lock cleanup routine
1464 is called on BeOS. [David Reid]
1466 *) Clear hook registrations between reads of the config file.
1467 When DSOs are unloaded and re-loaded the old hook pointers may
1468 no longer be valid. This fix eliminates potential segfaults.
1469 [Allan Edwards <ake@raleigh.ibm.com>]
1471 *) Fix a problem with Sigfunc not being defined or bypassed
1472 if sigaction() wasn't found. [Jim Jagielski]
1474 *) Fix the locking mechanism on BSD variants. They now use fcntl
1475 locks. This allows the server to start and serve pages.
1478 *) First cut at getting the Win32 installer to work
1479 [William Rowe <wrowe@lnd.com>]
1481 *) Get htpasswd compiling under Windows
1482 [William Rowe <wrowe@lnd.com>]
1484 *) Change the log message for a bind() failure to show the
1485 interface and port number. [Jeff Trawick]
1487 *) Import the documentation from 1.3.12 and bring parts of it
1488 up-to-date with respect to the changes that have occurred
1492 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
1493 now logged correctly on BeOS.
1496 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
1497 Makefile.win includes the same user interface as the old
1499 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
1501 *) Win32 exec now uses COMSPEC environment string for command
1502 shell path resolution.
1503 [William Rowe <wrowe@lnd.com>] PR#3715
1505 *) Win32: ap_connect() was not returning correct error condition
1507 [Allen Prescott <allen@clanprescott.com>]
1509 *) Win32: ap_open() was broken on Win9x because an NT-specific
1510 flag was passed to CreateFile. ap_puts() added an unnecessary
1512 [Jeff Trawick <trawick@us.ibm.com>]
1514 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
1515 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
1516 confusing ee/et name and made all extensions language/dialect
1517 rather than country reflecting. Changed example files to
1518 explicit reflect the ISO charset and added a few common
1519 ones to the example config [dirkx]
1521 *) Extend external module capability. To use this, you call
1522 configure with --with-module=path/to/mod1,path/to/mod2,etc.
1525 *) Backported the various "default charset" fixes from 1.3.12,
1526 including the AddDefaultCharset directive. [Jim Jagielski]
1528 *) Added the capability to do ${ENVVAR} constructs in the
1529 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
1530 it does this on a line by line basis; i.e. if the envvar
1531 expands to something with spaces you have to protect it
1532 by adding quotes around it (Unless of course you expect it
1533 to contains more than one argument. Alternatively you
1534 can compile it on a per token basis; which is what people
1535 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
1536 hampers fancier hacks.
1537 [Dirk-Willem van Gulik]
1539 *) Changed the 'ErrorDocument' syntax in that it NO longer
1540 supports the asymetric
1542 ErrorDocument 301 "Some message
1544 Note the opening " quote, without a closing quote. It now
1545 has either the following syntaxes
1547 ErrorDocument XXX /local/uri
1548 ErrorDocument XXX http://valid/url
1549 ErrorDocument XXX "Some Message"
1551 The recognition heuristic is: if it has a space it
1552 is a message. If it has no spaces and starts with a /
1553 or is a valid URL then treat it that way. Otherwise it
1554 is assumed to be a message.
1556 This breaks backward compatibility but makes live a hell
1557 of a lot easier for GUI's and config file parsers.
1558 [Dirk-Willem van Gulik]
1560 *) Changed 'CacheNegotiatedDocs' from its present/not-present
1561 syntax into a 'on' or 'off' syntax. As it currently is the
1562 only non nesting token which uses NO_ARGS and thus is an
1563 absolute pain for any config interface automation. This
1564 breaks backward compatibility. [Dirk-Willem van Gulik]
1566 *) Add ability to add external modules to the build process. This is
1567 done with --with-module=/path/to/module. Modules can only be added
1568 as static modules at this point.
1571 Changes with Apache 2.0a1
1573 *) Fix FreeBSD 3.3 core dump.
1574 Basically, ap_initialize() needs to get called before
1575 create_process(), since create_process() passes op_on structure
1576 to semop() to get a lock, but op_on isn't initialized until
1577 ap_initialize() calls setup_lock(). Here is a slight
1578 rearrangement to main() which calls ap_initialize() earlier...
1579 [Jeff Trawick <trawick@us.ibm.com>]
1581 *) Enable Apache to use sendfile/TransmitFile API
1582 [Bill Stoddard, David Reid, Paul Reder]
1584 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
1588 *) Make file I/O and network I/O writev/sendv APIs consistent.
1589 Eliminate use of ap_iovec_t and use Posix struct iovec.
1590 Use seperate variable on ap_writev to set the number of iovecs
1591 passed in and number of bytes written.
1594 *) Adapt file iol to use APR functions. Replaced ap_open_file()
1595 with ap_create_file_iol(). ap_create_file_iol() requires that
1596 the file be opened prior to the call using ap_open().
1599 *) Port mod_include and mod_cgi to 2.0
1600 [Paul Reder, Bill Stoddard]
1602 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
1603 bytes_read/bytes_written is always valid (never -1). Plus
1604 some fixes to buff.c to correct problems introduced by the
1605 errno => ap_status_t changes a while back. Plus a fix to
1606 chunked encoding introduced right at the beginning of 2.0.
1609 *) Revamped UNIX build system to use autoconf and libtool.
1610 [Manoj Kasichainula, Sascha Schumann]
1612 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
1614 *) More rigorous checking of Host: headers to fix security problems
1615 with mass name-based virtual hosting (whether using mod_rewrite
1616 or mod_vhost_alias).
1617 [Ben Hyde, Tony Finch]
1619 *) Add back support for UseCanonicalName in <Directory> containers.
1620 [Manoj Kasichainula]
1622 *) Added APLOG_STARTUP log type. This allows us to write an error
1623 message without any of the date and time information. As a part
1624 of this change, I also removed all of the calls to fprintf(stderr
1625 and replaced them with calls to ap_log_error using APLOG_STARTUP
1626 writing to stderr is no longer portable, because we don't direct
1627 stderr to the error log on all platforms.
1630 *) Convert error logging functions to take errno as an argument.
1631 This makes our error logs more portable, because some Windows API's
1632 don't set errno. This change allows us to still output a valid
1633 message on all of our platforms.
1636 *) mod_mime_magic runs in 2.0-dev now.
1637 [Paul Reder <rederpj@raleigh.ibm.com>]
1639 *) sendfile has been added to APR.
1640 [John Zedlewski <zedlwski@Princeton.EDU>]
1642 *) buff.c has been converted to no longer use errno.
1643 [Manoj Kasichainula]
1645 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
1646 interface adaption to APR functions did it. [Martin Kraemer]
1648 *) Support DSOs properly on 32-bit HP-UX 11.0
1649 [Dilip Khandekar <dilip@cup.hp.com>]
1651 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
1652 [Ralf S. Engelschall]
1654 *) Cleaned APR build environment integration and bootstrap APR
1655 automatically for developers from src/Configure.
1656 [Ralf S. Engelschall]
1658 *) Fixed building of src/support/htpasswd.c
1659 [Ralf S. Engelschall]
1661 *) When generating the Location: header, mod_speling forgot
1662 to escape the spelling-fixed uri. (Forw-Port from 1.3)
1665 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
1667 *) Change all pools to APR contexts. This is the first step to
1668 incorporating APR into Apache. [Ryan Bloom]
1670 *) Move "handler not found" warning message to below the check
1671 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
1672 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
1674 *) Support line-continuation feature in config.option file and
1675 allow the loading of multiple option sections at once via
1676 ``--with-option=<section1>,<section2>,...''
1677 [Ralf S. Engelschall]
1679 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
1681 Changes with Apache MPM
1683 *) Use asynchronous AcceptEx() and a completion port to accept and
1684 dispatch connections to threads in Windows NT/2000.
1687 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
1690 *) Implement the APACI --with-option facility
1691 (per default used the config.option file).
1692 [Ralf S. Engelschall]
1694 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
1696 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
1697 Replace pre_connection module call with a register_hook call and
1698 implement pre_connection as a hook. The intent is that these hooks will
1699 be extended to allow Apache to be multi-protocol, and also to allow the
1700 calling order to be specified on a per-hook/per-module basis.
1703 *) Implement mpm_* methods as "modules". Each method gets its own
1704 subdir in src/modules (eg: src/modules/prefork). Selection
1705 of method uses Rule MPM_METHOD. [Jim Jagielski]
1707 *) Port the hybrid server from the apache-apr repository as
1708 mpm_mpmt_pthread. [Manoj Kasichainula]
1710 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
1711 amongst the unix MPMs.
1713 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
1714 signal handling for the new world order. [Dean Gaudet]
1716 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
1717 of alloc.c for now. [Dean Gaudet]
1719 *) Handle partial large writes correctly. [Ben Laurie]
1721 *) Eliminate conn_rec's pointer to server. All it knows is the base server
1722 based on IP/port. [Ben Laurie]
1724 *) Port a bunch of modules to the new module structure.
1725 ["Michael H. Voase" <mvoase@midcoast.com.au>]
1727 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
1729 *) Basic restructuring to introduce the MPM concept; includes various
1730 changes to the module API... better described by
1731 docs/initial_blurb.txt. [Dean Gaudet]
1733 Changes with Apache pthreads
1735 *) New buff option added: BO_TIMEOUT. It describes the timeout for
1736 buff operations (generally over a network).
1737 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
1739 *) Created http_accept abstraction. Added 4 new functions (not exported):
1740 init_accept(), begin_accepting_requests(), get_request(),
1741 stop_accepting_requests() [Bill Stoddard]
1743 *) Fix to ap_rprintf call that allows mod_info to work properly.
1744 [James Morris <jmorris@intercode.com.au>]
1746 *) user and ap_auth_type fields were moved from connection_rec to
1747 request_rec. [Ryan Bloom]
1749 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
1750 needed in a threaded server.
1752 *) Initial pthread implementation from from Dean's apache-nspr code.
1753 [Bill Stoddard, Ryan Bloom]
1756 Changes with Apache 1.3.9
1758 *) Remove bogus error message when a redirect doesn't set Location.
1759 Instead, use an empty string to avoid coredump if the error message
1760 was supposed to include a location. [Roy Fielding]
1762 *) Don't allow configure to include mod_auth_digest unless it is
1763 explicitly requested, even if the user asked for all modules.
1766 *) Translate module names to dll names for OS/2 so that they are no more
1767 than 8 characters long and have an extension of "dll" instead of "so".
1770 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
1771 Fix test-compile check to check for randbyte instead of trand32.
1772 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
1773 and tweak to make Amaya happier. [Ronald Tschalär]
1775 *) Ensure that the installed expat include files are world readable,
1776 just like the other header files. [Martin Kraemer]
1778 *) Fixed generated AddModule adjustments in APACI's `configure' script
1779 in order to allow (new) modules like mod_vhost_alias to be handled
1780 correctly (which was touched by the adjustments for mod_alias).
1781 [Ralf S. Engelschall]
1783 *) For binary builds, add -R flag to apachectl to work around the lack of
1784 an absolute path to the ./libexec directory where the libhttp.ep file
1785 is needed for SHARED_CORE architectures. [Randy Terbush]
1787 *) WIN32: Create the CGI script process as DETACHED. This may solve the
1788 problem observed by some Win95/98 users where they get CGI script
1789 output sent to the console. [Bill Stoddard]
1791 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
1792 routines are now called ap_base64* and are 'plain' (i.e., no
1793 pool access or anything clever). Inside util.c the routines acting
1794 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
1795 The oddly named ap_uuencode(), ap_uudecode() are kept around for
1796 now but deprecated. [dirkx]
1798 *) Clean up the base64 and SHA1 additions and make sure they are
1799 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
1800 files. [Roy Fielding]
1802 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
1803 checking. Allow compiling on VS 6.0. [Randy Terbush]
1805 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
1807 *) Use TestCompile to search for the truerand library (rather than blindly
1808 assuming its existence). If it is not found, complain (but do not
1809 exit - yet). [Martin Kraemer]
1811 *) We forgot to add the new exported function names to
1812 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
1814 *) Add description of -T command-line option to usage().
1815 [Ralf S. Engelschall]
1817 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
1818 searched only AFTER libap has been searched, because libap needs
1819 some symbols from libos. [Martin Kraemer]
1821 *) Fix conflict with original mod_digest related to the symbol of the
1822 module dispatch list (which has to be unique for DSO and follow the
1823 usual conventions for the installation procedure).
1824 [Ralf S. Engelschall]
1826 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
1827 for other platforms as well. [Martin Kraemer]
1829 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
1830 types by AP_LONG and replace reference to renamed variable 'ubuf'
1831 by 'buffer'. [Martin Kraemer]
1833 Changes with Apache 1.3.8 [not released]
1835 *) Flush the output buffer immediately after sending an error or redirect
1836 response, since the result may be needed by the client to abort a
1837 long data transfer or restart a series of pipelined requests.
1838 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
1840 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
1841 [Ian Turner <iant@sequent.com>] PR#4735
1843 *) Local struct mmap in http_core.c conflicted with system structure
1844 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
1846 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
1847 [Ronald Tschalär <ronald@innovation.ch>]
1849 *) Fix a memory leak where the module counts were getting messed
1850 up across restarts. [David Harris <dharris@drh.net>]
1852 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
1853 properly in mod_access.
1854 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
1856 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
1857 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
1859 *) PORT: Support for compaq/tandem/com.
1860 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
1862 *) Added SHA1 password encryption support to easy migration from
1863 Netscape servers. See support/SHA1 for more information.
1864 Caused the separation of ap_md5.c into md5, sha1 and a general
1865 ap_checkpass.c with just a validate_passwd routine. Added a
1866 couple of flags to support/htpasswd. Some reuse of the to64()
1867 function; hence renamed to ap_to64().
1868 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
1870 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
1871 with ASCII/EBCDIC conversions in "ident" query.
1872 [David McCreedy <McCreedy@us.ibm.com>]
1874 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
1875 Change "Power Macintosh" to Power* so if uname prints "Power Book"
1876 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
1878 *) Fix SIGSEGV on some systems because the Vary fix below included
1879 a call to table_do with a variable argument list that was not
1880 NULL terminated. Replaced with better implementation. [Roy Fielding]
1882 Changes with Apache 1.3.7 [not released]
1884 *) The "Vary" response header field is now sanitised right before
1885 the header is sent back to the client. Multiple "Vary" fields
1886 are combined, and duplicate tokens (e.g., "Vary: host, host" or
1887 "Vary: host, negotiate, host, accept-language") are reduced to
1888 single instances. This is a better solution than the force-no-vary
1889 one (which is still valid for clients that can't cope with Vary
1890 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
1892 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
1894 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
1895 least on Linux and FreeBSD for now.
1898 *) Win32: More apache -k restart work. Restarts are now honored
1899 immediately and connections in the listen queue are -not- lost.
1900 This is made possible by the use of the WSADuplicateSocket()
1901 call. The listeners are opened in the parent, duplicated, then
1902 the duplicates are passed to the child. The original listen sockets
1903 are not closed by the parent across a restart, thus the listen queue
1905 [Bill Stoddard <stoddard@raleigh.ibm.com>]
1907 *) Fix handling of case when a client has sent "Expect: 100-continue"
1908 and we are going to respond with an error, but get stuck waiting to
1909 discard the body in the pointless hope of preserving the connection.
1910 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
1912 *) Fix 'configure' to work correctly with SysV-based versions of
1913 'tr' (consistent with Configure's use as well). [Jim Jagielski]
1915 *) apxs: Add "-S var=val" option which allows for override of CFG_*
1916 built-in values. Add "-e" option which works like -i but doesn't
1917 install the DSO; useful for editing httpd.conf with apxs. Fix
1918 editing code so that multiple invocations of apxs -a will not
1919 create duplicate LoadModule/AddModule entries; apxs can now be
1920 used to re- enable/disable a module. [Wilfredo Sanchez]
1922 *) Win32: Update the server to use Winsock 2. Specifically, link with
1923 ws2_32.lib rather than wsock32.lib. This gives us access to
1924 WSADuplcateSocket() in addition to some other enhanced comm APIs.
1925 Win 95 users may need to update their TCP/IP stack to pick up
1926 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
1927 [Bill Stoddard stoddard@raleigh.ibm.com]
1929 *) Win32: Redirect CGI script stderr (script debug info) into the
1930 error.log when CGI scripts fail. This makes Apache on Win32
1931 behave more like Unix.
1932 [Bill Stoddard stoddard@raleigh.ibm.com]
1934 *) Fixed `httpd' usage display: -D was missing.
1935 [Ralf S. Engelschall] PR#4614
1937 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
1938 [Ralf S. Engelschall] PR#4561, PR#4562
1940 *) OS/2: Fix problem with accept lock semaphores where server would die with
1941 "OS2SEM: Error 105 getting accept lock. Exiting!"
1942 [Brian Havard] PR#4505
1944 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
1945 [Randy Terbush <randy@covalent.net>]
1947 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
1948 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
1950 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
1951 command potentially _is_ GCC. [Ralf S. Engelschall]
1953 *) Fix apxs build issues on AIX
1954 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
1956 *) DocumentRoot Checking: Under previous versions, when Apache
1957 first started up, it used to do a stat of each DocumentRoot to
1958 see if it existed and was a directory. If not, then an error
1959 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
1960 does not exist, you will get error messages in error_log. If
1961 the '-t' command line option is used (to check the configuration)
1962 the check of DocumentRoot IS performed. An additional command
1963 line option, '-T', has been added if you want to avoid the
1964 DocumentRoot check even when checking the configuration.
1967 *) Win32: The query switch "apache -S" didn't exit after showing the
1968 vhost settings. That was inconsistent with the other query functions.
1969 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
1971 *) Win32: Changed behaviour of apache -k restart.
1972 Previously, the server would drain all connections in the stack's
1973 listen queue before honoring the restart. On a busy server, this
1974 could take hours. Now, a restart is honored almost immediately.
1975 All connections in Apache's queues are handled but connections in
1976 the stack's listen queue are discarded. Restart triggered by
1977 MaxRequestPerChild is unchanged.
1978 [Bill Stoddard <stoddard@raleigh.ibm.com>]
1980 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
1981 the accept loop. Good for a 5% performance boost. Cleaned up
1982 parent/child process management code.
1983 [Bill Stoddard <stoddard@raleigh.ibm.com>]
1985 *) Added ceiling on file size for memory mapped files.
1986 [John Giannandrea <jg@meer.net>] PR#4122
1988 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
1989 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
1990 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
1992 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
1993 use this at least for Expat. [Ralf S. Engelschall]
1995 *) Allow .module files to specify libraries with Lib:.
1998 *) Allow SetEnvIf[NoCase] to test environment variables as well
1999 as header fields and request attributes. [Ken Coar]
2001 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
2002 content-types are "text/html;parameters". PR#4524 [Ken Coar]
2004 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
2005 never accepted into any standard, and it opens up certain DoS
2006 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
2008 *) TestCompile updated. We can now run programs and output the
2009 results during the Configure process. [ Jim Jagielski]
2011 *) The source is now quad (long long) aware as needed. Specifically,
2012 the Configure process determines the correct size of off_t and
2013 *void. When the OS/platform/compiler supports quads, ap_snprintf()
2014 provides for the 'q' format qualifier (if quads are not available,
2015 'q' is silently "demoted" to long). [Jim Jagielski]
2017 *) When the username or password fed to htpasswd is too long, include the
2018 size limit in the error message. Also report illegal characters
2019 (currently only ':') in the username. Add the size restrictions
2020 to the man page. [Ken Coar]
2022 *) Fixed the configure --without-support option so it doesn't result in
2023 an infinite loop. [Marc Slemko]
2025 *) Piped error logs could cause a segfault if an error occured
2026 during configuration after a restart.
2027 [Aidan Cully <aidan@panix.com>] PR#4456
2029 *) If a "Location" field was stored in r->err_headers_out rather
2030 than r->headers_out, redirect processing wouldn't find it and
2031 the server would core dump on ap_escape_html(NULL). Check both
2032 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
2033 if Location isn't set. [Doug MacEachern, Ken Coar]
2035 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
2036 of the Expat 1.0.2 distribution. [Greg Stein]
2038 *) Replace regexec() calls with calls to a new API stub function
2039 ap_regexec(). This solves problems with DSO modules which use the regex
2040 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
2042 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
2043 environment variables can be set according to the protocol version
2044 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
2046 *) Add DSO support for OpenStep (Mach 4.2) platform.
2047 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
2049 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
2050 [Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
2052 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
2053 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
2055 *) Better DSO flags recognition on NetBSD platforms using ELF.
2056 [Todd Vierling <tv@pobox.com>] PR#4310
2058 *) Always log months in english format for %t in mod_log_config.
2059 [Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
2061 *) Support for server-parsed and multiview-determined ReadmeName and
2062 HeaderName files in mod_autoindex. Removed the restriction on
2063 "/"s in ReadmeName and HeaderName directives since the *sub_req*
2064 routines will deal with the access issues. (It's now possible to
2065 have {site|group|project|customer|...} wide readmes and headers.)
2066 [Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
2069 *) When stat() fails, don't assume anything about the contents of
2070 the struct stat. [Ed Korthof <ed@bitmechanic.com>]
2072 *) It's OK for a semop to return EINTR, just loop around and try
2073 again. [Dean Gaudet]
2075 *) Fix configuration engine re-entrant hangups, which solve a
2076 handful of problems seen with mod_perl <Perl> configuration sections
2077 [Salvador Ortiz Garcia <sog@msg.com.mx>]
2079 *) Mac OS and Mac OS X Server now use the appropriate custom layout
2080 by default when building with APACI; allow for platform-specific
2081 variable defaults in configure. [Wilfredo Sanchez]
2083 *) Do setgid() before initgroups() in http_main; some platforms
2084 zap the grouplist when setgid() is called. This was fixed in
2085 suexec earlier, but the main httpd code missed the change.
2086 [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2579
2088 *) Add recognition of .tgz as a gzipped tarchive.
2089 [Bertrand de Singly <bertrand.de-singly@polytechnique.fr>] PR#2364
2091 *) mod_include's fsize/flastmod should allow only relative paths, just
2092 like "include file". [Jaroslav Benkovsky <benkovsk@pha.pvt.cz>]
2094 *) OS/2: Add support for building loadable modules using DLLs.
2097 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
2100 *) Fix minor but annoying bug with the test for Configuration.tmpl
2101 being newer than Configuration so that it is less likely to fail
2102 when using APACI and shadow sources. [Wilfredo Sanchez]
2104 *) PORT: Add initial support for Mac OS (versions 10.0 and
2105 greater). Use Mac OS X Server layout for now. Clean up dyld code
2106 in unix/os.c, and don't install the dyld error handlers, which
2107 are no longer needed in Mac OS. [Wilfredo Sanchez]
2109 *) Rename Rhapsody layout to "Mac OS X Server". Change install
2110 locations to appropriate ones for user-built (as opposed to
2111 system) installs. [Wilfredo Sanchez]
2113 *) Modify mod_autoindex's handling of AddDescription so that the
2114 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
2116 *) Add functionality to the install-bindist.sh script created by
2117 binbuild.sh to use tar when copying distribution files to the
2118 serverroot. This allows upgrading an existing installation
2119 without nesting the new distribution in the old.
2121 install-bindist.sh now detects the local perl5 path to install
2122 apxs and dbmmanage with proper path to perl interpreter.
2124 Add an install-binsupport target which copies the source files
2125 for apxs and dbmmanage to bindist to allow these scripts to
2126 be properly installed relative to the destination serverroot.
2127 [Randy Terbush, Covalent Technologies, randy@covalent.net]
2129 *) Fix intermittent SEGV in ap_proxy_cache_error() in
2130 src/modules/proxy_util.c where a NULL filepointer and
2131 temporary filename were closed and unlinked.
2132 [Graham Leggett <minfrin@sharp.fm>,

2135 *) Fix inconsistent error messages reported by mod_proxy.
2136 [Graham Leggett <minfrin@sharp.fm>]
2138 *) OS/2: Fix terminating CGIs that aren't compiled by EMX GCC when a
2139 connection is aborted. [Brian Havard]
2141 *) Force the LANG envariable to the known state of "C" so that we
2142 have assurance about how string manipulators (e.g., tr) will
2143 function. [Ken Coar] PR#1630
2145 *) Add a directive to allow customising of the tracking cookie name.
2146 [Ken Coar] PR#2921, 4303
2148 *) Add "force-no-vary" envariable to allow servers to work around
2149 clients that choke on "Vary" fields in the response header.
2150 [Ken Coar, Dmitry Khrustalev <dima@zippy.machaon.ru>] PR#4118
2152 *) Fixed a bug in mod_dir that causes a child process will infinitely
2153 recurse when it attemps to handle a request for a directory wnd the
2154 value of the DirectoryIndex directive is a single dot. Also likely
2155 to happen for anyother values of DirectoryIndex that will map back
2156 to the same directory. The handler now only considers regular files
2157 as being index candidates. No PR#s found.
2158 [Raymond S Brand <rsbx@rsbx.net>]
2160 *) Ease configuration debugging by making TestCompile fall back to
2161 using "make" if the $MAKE variable is unset [Martin Kraemer]
2163 *) Fixed the ServerSignature directive to work as documented.
2164 [Raymond S Brand <rsbx@rsbx.net>] PR#4248
2166 *) Add "opt" (SysV-style) layout to config.layout. [Raymond S Brand
2169 *) Add APACI --without-execstrip option which can be used to disable the
2170 stripping of executables on installation. This is very important for DSO
2171 and debugging situations. [Ralf S. Engelschall]
2173 *) Add support for OS/2 (case insenstive filesystem, .exe suffix, etc)
2174 to APACI files and related scripts.

2189 *) Make sure RewriteLock can be used only in the global context, (i.e.
2190 outside of any <VirtualHost> sections) because it's a global facility of
2191 the rewrite engine. [Ralf S. Engelschall]
2193 *) Fix the ownership delegation for proxy directory under `make install'.
2194 [Ralf S. Engelschall]
2196 *) APACI would not correctly build suexec. [Maria Verina
2197 <mariav@icgeb.trieste.it>] PR#4260
2199 *) mod_mime_magic passed only the first 4k of a file to
2200 uncompress/gzip, but those tools sometimes do not produce
2201 any output unless a sufficient portion of the compressed
2202 file is input. Change to pass the entire file -- but

2239 *) Make {Set,Unset,Pass}Env per-directory instead of per-server.
2242 *) Correct an apparent typo: on the Windows and MPE platforms, the
2243 htpasswd utility was limiting passwords to only 8 characters.
2246 *) EBCDIC platforms: David submitted patches for two bugs in the
2247 MD5 digest port for EBCDIC machines:
2248 a) the htdigest utility overwrote the old contents of the digest file
2249 b) the Content-MD5 header value (ContentDigest directive) was wrong
2250 when the returned file was not converted from EBCDIC, but was a
2251 binary (e.g., image file) in the first place.
2252 [David McCreedy <mccreedy@us.ibm.com>]
2254 *) support/htpasswd now permits the password to be specified on the
2255 command line with the '-b' switch. This is useful when passwords
2256 need to be maintained by scripts -- particularly in the Win32
2257 environment. [Ken Coar]
2259 *) Win32: Win32 multiple services patch. Added capability to install and
2260 run multiple copies of apache as individual services.
2263 apache -n apache1 -i -f c:/httpd.conf
2264 Installs apache as service 'apache1' and associates c:/httpd.conf
2267 Starts apache1 service.

2289 *) Correct the signed/unsigned character handling for the MD5 routines;
2290 mismatches were causing compilation problems with gcc -pedantic and
2291 in the TPF cross-compilation. [Ken Coar]
2293 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
2294 a roughly 5 fold speed up. [Brian Havard]
2296 *) proxy ftp: instead of using the hardwired string "text/plain" as
2297 a fallback type for files served by the ftp proxy, use the
2298 ap_default_type() function to determine the configured type.
2299 This allows for special configurations like
2300 <Directory proxy:ftp://some.host>
2301 DefaultType gargle/blurb
2303 Additionally, add the Content-Encoding: header to FTP proxy replies
2304 when the encoding is defined (by the AddEncoding directive).
2305 Because it was missing, it was almost impossible to browse compressed
2306 files using the FTP proxy (works now perfectly in Communicator).
2307 The ftp proxy now also returns the Date: and Server: header lines (if not
2308 much else... This code is "somewhat" broken) like normal requests do.
2311 *) Be more smart in APACI's configure script when determining the UID/GID
2312 for User/Group directives and use the determined UID/GID to initialize
2313 the permissions on the proxycachedir.
2314 [Dirk-Willem van Gulik, Ralf S. Engelschall]
2316 *) Changed the forking-prior-to-cleanup in the proxy module to first
2317 check wether it actually needs to collect garbage. This reduces
2318 the number of fork()s from one/request to just the odd one an hour.
2319 [Dirk-Willem van Gulik]

2346 Changes with Apache 1.3.5 [not released]
2348 *) M_INVALID needed a value within the scope of METHODS so that unknown
2349 methods can be access controlled. [Roy Fielding] PR#3821
2351 *) Added PassAllEnv; makes server's entire environment available
2352 to CGIs and SSIs executed within directive's scope. [Ken Coar]
2354 *) ap_uuencode() always added two trailing '='s and encoding of
2355 8 bit characters on a machine with signed char may produced
2356 incorrect results. Additionally ap_uuencode() should now
2357 work correctly on EBCDIC platforms.
2358 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
2360 *) WIN32: Binary installer now runs the configuration DLL before
2361 the reboot prompt (which is only given if MSVCRT.DLL system
2362 DLL is new or updated). This should avoid the configuration
2363 directory being empty after installation. [Paul Sutton]
2364 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988
2366 *) WIN32: Binary installer now creates Start menu options to start
2367 and stop Apache as a console application and to uninstall
2368 the Apache service on NT. [Paul Sutton] PR#3741
2370 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
2372 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
2373 have been reported with flock() locking (probably related to kernel
2374 version). [Dean Gaudet] PR#2723, 3531
2376 *) Using APACI, the main config file (usually httpd.conf) was
2377 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez
2378 <wsanchez@apple.com>]
2380 *) PORT: AIX does not require the SHARED_CODE "hack"
2381 [Ryan Bloom <rbb@raleigh.ibm.com>]
2383 *) Set-Cookie headers were being doubled up for some CGIs by the O(n^2)
2384 avoidance code added in 1.3.3.
2385 [Dean Gaudet, Jeff Lewis <lewis@stanford.edu>] PR#3872
2387 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
2388 for 8-bit safeness. [Dean Gaudet]
2390 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
2391 because SPARCs have a small machine-specific maximum size for the Global
2392 Offset Table which is often exceeded when compiling one of the larger
2393 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
2395 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
2396 DSO/DLL section because it's a directive from mod_status and isn't
2397 available before the DLL of mod_status is loaded.
2398 [Martin POESCHL <mpoeschl@gmx.net>] PR#3936
2400 *) SECURITY: Fix a bug in the calculation of the buffer size for the line
2401 continuation facility in Apache's configuration files which could
2402 lead to a buffer overflow situation.
2403 [Thomas Devanneaux <Thomas.Devanneaux@enst.fr>] PR#3617
2405 *) Make documentation and error messages of APACI's --activate-module=FILE
2406 option more clear. [Jan Wolter <janc@wwnet.net>] PR#3995
2408 *) Fix the gcc version check (for enabling the `inline' facility) to
2409 really support all future gcc versions >= 2.7 until we know more.
2410 [John Tobey <jtobey@banta-im.com>] PR#3983
2412 *) Let APACI's configure script correctly complain for unknown --enable-XXX
2413 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
2415 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
2416 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
2417 possible buffer overflows. [Ralf S. Engelschall]
2419 *) Remove no longer used non-API function ap_single_module_init().
2420 [Ralf S. Engelschall]
2422 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
2425 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
2426 to make platform installations easier. [Wilfredo Sanchez]
2428 *) In configure, do not append the target name to the directory path if
2429 the path already contains "apache". [Ralf S. Engelschall]
2431 *) SIGPIPE is now ignored by the server core. The request write routines
2432 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
2433 correctly check for output errors and mark the connection as aborted.
2434 Replaced many direct (unchecked) calls to ap_b* routines with the
2435 analogous ap_r* calls. [Roy Fielding]
2437 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
2438 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
2439 Furthermore map lookups for non-existent keys are now cached as well.
2440 Additionally "txt" maps are now parsed with simple string functions
2441 instead of using ap_pregcomp(). As a side effect a bug that prevented
2442 the usage of keys containing the "," character was fixed.
2443 The changes drastically improve the performance when large rewrite maps
2445 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
2447 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
2448 other than GET, and const'd the definition of method in request_rec.
2451 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
2453 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
2454 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
2456 *) Add %V to mod_log_config, this logs the hostname according to the
2457 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
2458 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
2460 *) Add support for \n and \t to mod_log_config, can be used to produce
2461 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
2463 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
2465 *) Added informative error messages for failed munmap() and fseek() calls
2466 in http_core.c. [John Bley, Roy Fielding]
2468 *) Added some informative error messages for some failed malloc()
2469 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
2471 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
2472 is removed. This allows <Directory proxy:*> directives to work and
2473 prevents invalid requests from killing the process.
2474 [Brian Havard <brianh@kheldar.apana.org.au>]
2476 *) Reorganised FAQ document.
2477 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497
2479 *) src/support/: The ApacheBench benchmark program was overhauled by
2480 David N. Welton: you can now have it generate an HTML TABLE, presumably
2481 for integration into other HTML sources. David updated the ab man page
2482 as well and added some missing descriptions. Thanks!
2483 [David N. Welton <davidw@prosa.it>]
2485 *) Win32: The filename validity checker now allows filenames containing
2486 characters in the range 0x80 to 0xff (for example accented characters).
2487 [Paul Sutton] PR#3890
2489 *) Added conditional logging based upon environment variables to
2490 mod_log_config. mod_log_referer and mod_log_agent
2491 are now deprecated. [Ken Coar]
2493 *) Allow apache acting as a proxy server to relay the real
2494 reason of a failure to a client rather than the "internal
2495 server error" it does currently. The general exposure mechanism
2496 can be triggered by any module by setting the "verbose-error-to"
2497 note to "*"; this allows more than just proxy errors to be exposed.
2498 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
2500 *) Moved man pages for ab and apachectrl to section 8.
2501 [Wilfredo Sanchez, Roy Fielding]
2503 *) Added -S option to install.sh so that options can be passed to
2504 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
2506 *) Tweak modules Makefile generated by Configure so that it handles
2507 the test case of no modules being selected. [chaz@reliant.com]
2509 *) Added a <LimitExcept method ...> sectioning directive that allows
2510 the user to assign authentication control to any HTTP method that
2511 is *not* given in the argument list; i.e., the logical negation
2512 of the <Limit> directive. This is particularly useful for controlling
2513 access on methods unknown to the Apache core, but perhaps known by
2514 some module or CGI script. [Roy Fielding, Tony Finch]
2516 *) Prevent apachectl from complaining if the PIDFILE exists but
2517 does not contain a process id, as might occur if the server is
2518 being rapidly restarted. [Wilfredo Sanchez]
2520 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
2522 *) Entity tag comparisons for If-Match and If-None-Match were not being
2523 performed correctly -- weak tags might cause false positives. Also,
2524 strong comparison wasn't properly enforced in all cases.
2525 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
2527 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
2530 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
2531 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
2533 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
2534 to util.c for parsing an HTTP header field value to extract the next
2535 list item, taking into account the possible presence of nested comments,
2536 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
2537 insignificant whitespace and lowercases non-quoted tokens.
2538 [Roy Fielding] PR#2065
2540 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
2541 code different from 500. This allows the proxy to, e.g., return
2542 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
2544 *) Fix ordering of language variants for the case where the traditional
2545 negotiation algorithm is being used with multiple language variants
2546 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
2548 *) Do not round the TCN quality calculation to 5 decimal places,
2549 unlike RFC 2296, because the calculation might need 12 decimal places
2550 to get the right result. [Roy Fielding]
2552 *) Remove unused code to disable transparent negotiation when
2553 negotiating on encoding only, as we now handle encoding too
2554 (though this is nonstandard for TCN), remove charset=ISO-8859-1
2555 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
2556 some debugging statements within mod_negotiation. [Koen Holtman]
2558 *) Fixed a rare memory corruption possibility in mod_dir if the index
2559 file is negotiable and no acceptable variant can be found.
2560 [Dean Gaudet, Roy Fielding, Martin Kraemer]
2562 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
2563 searching the Win32 registry for script interpreters.
2566 *) Win32: The compiled-in default filename for the error log is now
2567 error.log, which matches the default in the distributed httpd.conf.
2570 *) Win32: Any error messages from -i or -u command line options are now
2571 displayed on the console output rather than sent to the error log.
2572 Also the "Running Apache..." message is not output unless Apache is
2573 going to serve requests. [Paul Sutton]
2575 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
2576 and use a private significator ('$apr1$') to mark passwords as
2577 being smashed with our own algorithm. Also abstract the password
2578 checking into a new ap_validate_password() routine. [Ken Coar]
2580 *) Win32: The filename validity checker now allows "COM" but refuses
2581 access to "COM1" through "COM4". This allows filenames such
2582 as "com.name" to be served. [Paul Sutton] PR#3769.
2584 *) BS2000: Adapt to the new ufork() system call interface which will
2585 make subtasking easier on the OSD/POSIX mainframe environment.
2588 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
2589 ap_compat.h. [David White <david@persimmon.com>] PR#3725
2591 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
2592 use `.db' instead of `.pag' not only for FreeBSD, but also when
2593 the NDBM library looks like Berkeley-DB based.
2594 [Ralf S. Engelschall] PR#3773
2596 *) Add ability to handle DES or MD5 authentication passwords.
2597 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
2599 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
2601 *) SECURITY: Avoid some buffer overflow problems when escaping
2602 quoted strings. (This overflow was on the heap and we believe
2603 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
2605 *) Let src/Configure be aware of CFLAGS options starting with plus
2606 signs as it's the case for the HP/UX compiler.
2607 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
2609 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
2610 and check to see if the tar we wind up with supports '-h'.
2611 [Jim Jagielski] PR#3671
2613 *) A consistent and conservative style for all shell scripts has been
2614 implemented. Basically, all shell string tests use the traditional
2615 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
2616 to protect against bare null variable strings (ie: wrapping both
2617 sides with double quotes and prepending 'x'). 'x' was chosen
2618 because it's more universal and hopefully easier for old shell
2619 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
2622 *) The status module now prints out both the main server generation as
2623 well as the generation of each process. Also, the vhost info is
2624 printed with '?notable'. [Jim Jagielski]
2626 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
2627 and this makes its functions available to things in src/support.
2630 Changes with Apache 1.3.4
2632 *) Renamed macros status_drops_connection to ap_status_drops_connection
2633 and vestigial scan_script_header to ap_scan_script_header_err,
2634 mostly for aesthetic reasons. [Roy Fielding]
2636 *) The query switch "httpd -S" didn't exit after showing the
2637 vhost settings. That was inconsistent with the other query functions.
2640 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
2641 filename to the end of the STANDARD_MODULE_STUFF. Its
2642 presence at the beginning prevented reporting of the filename
2643 for modules compiled before 1 January 1999. [Ken Coar]
2645 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
2646 to detect and prevent access to special DOS device file names.
2647 [Paul Sutton, Ken Parzygnat]
2649 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
2650 and Makefile_win32_debug.txt (debug build) that work on Win95.
2651 Run each of the following from the src directory:
2652 nmake /f Makefile_win32.txt # compiles normal build
2653 nmake /f Makefile_win32.txt install # compiles and installs
2654 nmake /f Makefile_win32.txt clean # removes compiled junk
2655 nmake /f Makefile_win32_debug.txt # compiles debug build
2656 nmake /f Makefile_win32_debug.txt install
2657 nmake /f Makefile_win32_debug.txt clean
2660 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
2661 to build binary distributions. [Lars Eilebrecht]
2663 *) IndexOptions SuppressColumnSorting only turned off making
2664 the column headers anchors; you could still change the display
2665 order by manually adding a '?N=A' or similar query string to the
2666 URL. Now SuppressColumnSorting locks in the sort order so
2667 it can't be overridden this way. [Ken Coar]
2669 *) Added IndexOrderDefault directive to supply a default sort order
2670 for FancyIndexed directory listings. [Ken Coar] PR#1699
2672 *) Change the ap_assert macro to a variant that works on all platforms.
2673 [Richard Prinz <richard.prinz@cso.net>] PR#2575
2675 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
2676 search for an underscore on dlsym() (as it's already the case
2677 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
2679 *) Small fix for mod_env.html: The module was documented as to be _not_
2680 compiled into Apache per default, although it _IS_ compiled into
2681 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
2683 *) Instead of fixing a bug in the generation procedure for config.status (a
2684 backslash was missing) we remove the bug together with it's complete
2685 context because the special cases of the past can now no longer occur
2686 because of the recent magic for the --with-layout default.
2687 [Ralf S. Engelschall] PR#3590
2689 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
2690 making sure the src/support/ tools are _forced_ to be build last (they
2691 depend on other libraries).
2692 [Markus Theissinger <markus.theissinger@gmx.de>]
2694 *) Fix installation procedure: Now that os-inline.c is actually used (a
2695 recently fixed bug prevented this) we need to also install os-include.c
2696 in addition to os.h into the PREFIX/include/ location or building of
2697 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
2699 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
2700 allow us to distinguish between a garbled DSO (or even a file which isn't
2701 an Apache module DSO at all) and a DSO which doesn't match the current
2702 Apache API. [Ralf S. Engelschall] PR#3152
2704 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
2705 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
2706 match case insensitive (this especially avoids nasty patterns like
2707 `[tT][eE][sS][tT]'). Second two additional internal map functions
2708 `escape' and `unescape' were added which can be used to escape/unescape
2709 to/from hex-encodings in URLs parts (this is especially useful in
2710 combination with map lookups).
2711 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
2713 *) Renamed the macro escape_uri() to ap_escape_uri() which was
2714 forgotten (because it was a macro) in the symbol renaming process.
2715 [Ralf S. Engelschall]
2717 *) Fix some inconsistencies related to the scopes of directives. The only
2718 user visible change is that the directives `UseCanonicalName' and
2719 `ContentDigest' now use the (more correct) `Options' scope instead of
2720 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
2722 *) Using DSO, the Server token was being mangled. Specifically, the
2723 module's token was being added first before the Apache token. This
2724 has been fixed. [Jim Jagielski]
2726 *) Major overhaul of mod_negotiation.c, part 2.
2727 - properly handle "identity" within Accept-Encoding.
2728 - allow encoded variants in RVSA negotiation and let them appear in
2729 the Alternates field using the non-standard "encoding" tag-list.
2730 - fixed both negotiation algorithms so that an explicitly accepted
2731 encoding is preferred over no encoding if "identity" is not
2732 included within Accept-Encoding.
2733 - added ap_array_pstrcat() to alloc.c for efficient concatenation
2734 of large substring sequences.
2735 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
2738 *) Major overhaul of mod_negotiation.c, part 1.
2739 - cleanups to mod_negotiation comments and code structure
2740 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
2741 support for everything in the upcoming HTTP/1.1
2742 revision (draft-ietf-http-v11-spec-rev-06.txt).
2743 - language tag matching also handles tags with more than 2
2745 - empty Accept, Accept-Language, Accept-Charset headers are
2746 processed correctly; previously an empty header would make all
2747 values acceptable instead of unacceptable.
2748 - allowed for q values in Accept-Encoding
2749 - added support for transparent content negotiation (rfc2295 and
2750 rfc2296) (though we do not implement all features in these drafts,
2751 e.g. no feature negotiation). Removed old experimental version.
2752 - implemented 'structured entity tags' for better cache correctness
2753 (structured entity tags ensure that caches which can deal with Vary
2754 will (eventually) be updated if the set of variants on the server
2756 - this involved adding a vlist_validator element to request_rec
2757 - this involved adding the ap_make_etag() function to the global API
2758 - modified guessing of charsets used by Apache negotiation algorithm
2759 to guess 'no charset' if the variant is not a text/* type
2760 - added code to sort multiviews variants into a canonical order so that
2761 negotiation results are consistent across backup/restores and mirrors
2762 - removed possibility of a type map file resolving to another type map
2763 file as its best variant
2764 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
2766 *) RFC2396 allows the syntax http://host:/path (with no port number)
2767 but the proxy disallowed it (ap_proxy_canon_netloc()).
2768 [David Kristol <dmk@bell-labs.com>] PR#3530
2770 *) When modules update/modify the file name in the configfile_t structure,
2771 syntax errors will report the updated name, not the original one.
2772 [Fabien Coelho <coelho@cri.ensmp.fr>] PR#3573
2774 *) Correct some filename case assumptions from WIN32 to
2775 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]
2777 *) For %v log ServerName regardless of the UseCanonicalName
2778 setting (similarly for %p). [Dean Gaudet]
2780 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
2781 rather late (too late for some invocations of TestCompile).
2782 This improves the make environment available to TestCompile and
2783 the *.module scripts. [Martin Kraemer]
2785 *) The hashbang emulation code in ap_execve.c would interpret
2786 #!/hashbang/scripts correctly, but failed to fall back to a
2787 standard shell for scripts which did NOT start with #!
2788 Now SHELL_PATH is started in these cases. [Martin Kraemer]
2790 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
2793 *) Update APXS manual page: some -q option arguments were missing
2794 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
2796 *) Cleanup the command line options: `-?' was documented to show
2797 the usage list but does it with an error because `?' is not a valid
2798 command. OTOH a lot of users expect `-h' to print such a usage list and
2799 instead are annoyed for ages by our huge unreadable list of directives.
2800 So we now changed the command line options this way:
2802 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
2803 very similar to the popular linker option.
2805 Intent: while -l gives the small list of modules, -L now gives the
2806 large list of directives implemented by these modules. This is also
2807 consistent with -v (short version info) and -V (large version info).
2809 Intent: it's now the expected option ;-)
2810 The manual page was adjusted accordingly.
2811 [Ralf S. Engelschall] PR#2714
2813 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
2814 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
2816 *) Removed recently introduced bugs and disfigurements in APACI:
2817 o fixed argument line processing: using $args was broken: It was not
2818 initialized and using args="$args $apc_option" and even args="$args
2819 \"$apc_option\"" fails in the second processing round for any arguments
2820 containing whitespaces. The only correct way is to use the construct
2821 "$@" (but not possible here) or iterate _both_ times over the implicit
2822 argument line (no argument to for-loop) which is what we now use.
2823 o make --with-layout=Apache the default without creating
2824 redundancy (copying the --with-layout block in the argument parsing
2825 loop). We achieve this by using the "$@" construct together with the
2826 `set' command to prepend --with-layout=Apache to the command line in
2827 case --with-layout is not used.
2828 o fixed auto-suffix handling now that config.layout exists.
2829 Paths which are auto-suffixed are marked with a trailing plus sign in
2830 config.layout and every path now can be marked this way (not only the
2831 four paths for which we do it currently). Additionally the suffix is
2832 no longer a static one. Instead it's now `/<target>' where <target> is
2833 the argument of the --target option or per default `httpd'.
2834 o allow also tabs (and only spaces) where we match whitespaces
2835 o various fixes and cleanups related to used shell coding style
2836 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
2837 o trimmed output of --help to fit into 80 columns
2838 [Ralf S. Engelschall]
2840 *) Added two new core API functions, ap_single_module_configure() and
2841 ap_single_module_init(), which are now used by mod_so to configure a module
2842 after loading. [Ralf S. Engelschall]
2844 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
2845 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
2846 of ap_config.h to allow serialized accept for multiport listens.
2847 [Roy Fielding, Curt Sampson] PR#3120
2849 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
2850 of ap_config.h that would skip several defines if DEFAULT_GROUP
2851 was overridden. [Roy Fielding]
2853 *) PORT: The I86 version of DGUX has support for strncasecmp and
2854 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
2856 *) Fix ordering of definitions in ap_config.h so that ap_inline is
2857 defined before it might be used. [Victor Khimenko]
2859 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
2860 [Tom Serkowski <tks@bsdi.com>] PR#3453
2862 *) Make generation of src/Configuration.apaci more robust: It failed to
2863 differenciate between modules when one module name was a postfix of
2864 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
2865 just XXX (think about totally non-standard names like "apache_ssl", too).
2866 [Ralf S. Engelschall] PR#3380
2868 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
2869 since 1.3b7) and make whitespace handling more robust (it failed horrible
2870 when whitespaces were present in the arguments of -D options).
2871 [Ralf S. Engelschall] PR#3240
2873 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
2874 creates an external package shadow tree in DIR before the local build
2875 shadow tree is generated under DIR. This way one can have the extracted
2876 Apache distribution tree read-only on NFS or CDROM and still build Apache
2877 from these sources. An automatically triggered VPATH-like mechanism is
2878 provided through the TOP variable, too.
2879 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez@apple.com>]
2881 *) Fix negotiation so that a Vary response header is correctly
2882 generated when, for a particular dimension, variants only vary
2883 in having or not having a value for that dimension. [Paul Sutton]
2885 *) Fix negotiation so that we prefer an encoded variant over an
2886 unencoded variant if the user-agent explicitly says it can
2887 accept that encoding. Previously we always preferred the unencoded
2889 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
2891 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
2892 and the usage page was inconsistent with the functionality and manpage.
2893 [Ralf S. Engelschall]
2895 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
2896 They can occur multiple times and their arguments (`xxx') are passed AS
2897 IS to the compiler/linker command. [Ralf S. Engelschall]
2899 *) Fixed possible (but harmless in practice) bug in the DBM lookup
2900 procedure of mod_rewrite: very long keys were truncated.
2901 [Ralf S. Engelschall]
2903 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
2904 identifier, currently "Apache" and "GNU" are pre-defined in the file
2905 config.layout. Custom layouts are possible by using FILE:ID as the
2906 argument where the layout ID is taken from FILE.
2908 The config.layout file consists of <Layout ID>..</Layout> sections
2909 where inside those sections "path_variable: path_value" pairs can be
2910 specified. These lines are converted to path_variable='path_value'.
2912 *) Add a DefaultLanguage directive so that files missing a language
2913 extension (e.g., .fr, .de) can be labelled as being some other
2914 default language. DefaultLanguage can appear in <Directory> and
2915 <Files> containers as well as .htaccess files. [Paul Sutton]
2918 *) Fix TARGET configuration when configuring and installing using
2919 APACI configure. TARGET now defines the basename of the configuration
2920 file, startup script, manual page, etc. log_error_core() now reports
2921 the server binary name given by argv[0]. TARGET can now also be defined
2922 with --target=TARGET parameter passed to APACI configure.
2923 [Ralf Engelschall, Randy Terbush]
2925 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
2926 rather than OPT_INCLUDES [Rainer Schoepf <schoepf@uni-mainz.de>]
2928 *) ap_md5_binary() was using sprintf() rather than a table lookup
2929 to convert binary bytes to hex digits.

2944 *) Ignore a "ErrorDocument 401" directive with a full URL and write a
2945 notice to the error log. It is not possible to send a 401 response
2946 and a redirect at the same time. [Lars Eilebrecht]
2948 *) Fallback to native compilers for IRIX-32 platform. It seems that
2949 a gcc 2.8.1 compiled apache is logging client addresses with all
2950 bits set (255.255.255.255). This is the second such problem caused
2951 by gcc 2.8.1 compiler. The first being broken semaphore locking.
2954 *) Updated mime.types to reflect current Internet media types
2955 and include a URL to the registry.
2956 [Manoj Kasichainula, Roy Fielding] PR#2380, 2286, 2246
2958 *) SECURITY: Do a more complete check in mod_include to avoid
2959 an infinite loop of recursive SSI includes. [Marc Slemko] PR#3323
2961 *) Add APACI --suexec-docroot and --suexec-logfile options which can be
2962 used to set the document root directory (DOC_ROOT) and the suexec
2963 logfile (LOG_EXEC), respectively. Additionally the --layout option
2964 was changed to show more information about the suEXEC setup.
2965 [Lars Eilebrecht] PR#3316, 3357, 3361
2967 *) Added the last two WebDAV status codes of 424 (Failed Dependency)
2968 and 507 (Insufficient Storage) for use by third-party modules.
2971 *) Enabled all of the WebDAV method names for use by third-party
2972 modules, Limit, and Script directives. That includes PATCH,
2973 PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.
2974 Improved mod_actions.c so that it can use any of the methods
2975 defined in httpd.h. Added ap_method_number_of(method) for
2976 getting the internal method number. [Roy Fielding]
2978 *) PORT: Add a port to the TPF OS. [Joe Moenich <moenich@us.ibm.com> and

2998 script failed, including the command line used to attempt to execute
2999 the interpreter and the Win32 error code returned. [Marc Slemko]
3001 *) Disable sending of error-notes on a 500 (Internal Server Error) response
3002 since it often includes file path info. Enable sending of error-notes
3003 on a 501 (Method Not Implemented). [Roy Fielding] PR#3173
3005 *) http_config.c would respond with 501 (Method Not Implemented) if a
3006 content type handler was specified but could not be found, which
3007 should have been a 500 response. Likewise, mod_proxy.c would responsd
3008 with a 501 if the URI scheme is unrecognized instead of the correct
3009 response of 403 (Forbidden). [Roy Fielding]
3011 *) SECURITY: Eliminate DoS attack when a bad URI path contains what
3012 looks like a printf format escape. [Marc Slemko, Studenten Net Twente]
3014 *) Fix in mod_autoindex: for files where the last modified time stamp was
3015 unavailable, an empty string was printed which was 2 bytes short.
3016 The size and description columns were therefore not aligned correctly.
3017 [Martin Kraemer] (no PR#)
3019 *) Update BS2000 OS code to work with recent versions. Starting with
3020 release A17, the child fork() must be replaced by a _rfork().
3021 (BS2000 only) [Martin Kraemer]
3023 *) Add the actual server_rec structure of the specific Vhost to the
3024 scoreboard file and avoid a string copy (as well as allow some
3025 further future enhancements). [Harrie Hazewinkel
3026 <harrie.hazewinkel@jrc.it>]
3028 *) Add APACI --permute-module=foo:bar option which can be used to
3029 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
3030 in the Configuration[.apaci] file. Two special and important variants are
3031 supported for the option argument: first BEGIN:foo which permutes module
3032 mod_foo with the begin of the module list, i.e. it `moves' the module to
3033 the begin of the list (gives it lowest priority). And second foo:END
3034 which permutes mod_foo with the end of the module list, i.e. it `moves'
3035 the module to the end of the list (gives it highest priority).

3043 on container start lines (e.g., it wouldn't spot

3048 all handler associations for the specified file extensions.

3077 *) Add a "default-handler" handler that calls the default_hander()
3078 function which is normally called for static content. This allows
3079 you to override a specific handler. [Marc Slemko]

3082 hard-coded syntax check with a call to a routine we already created to
3083 do this. [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2976, 3074

3086 in mod_auth if we know that we know that no other module can
3087 deal with it. [Marc Slemko]
3089 *) Remove ap_private_extern method of hiding conflicting symbols
3090 on the NEXT platform because it is not correct for all versions,
3091 and the versions for which it is correct are unknown.

3104 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
3106 Changes with Apache 1.3.3
3108 *) Added a complete implementation of the Expect header field as
3109 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
3110 response when we already know the final status, which is mighty
3111 useful for PUT responses that result in 302 or 401. [Roy Fielding]
3113 *) Remove extra trailing whitespace from the getline results as part
3114 of the protocol processing, which is extra nice because it works
3115 between continuation lines, is almost no cost in the normal case
3116 of no extra whitespace, and saves memory. [Roy Fielding]
3118 *) Added new HTTP status codes and default response bodies from the
3119 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
3120 HTTP Extension Framework (510) specifications. Did not add the
3121 WebDAV 424 and 425 codes because they are bogus. We don't use any
3122 of these codes yet, but they are now available to 3rd-party modules.
3125 *) Fix a possible race condition between timed-out requests and the
3126 ap_bhalfduplex select that might result in an infinite loop on

3238 You now must define a BS2000Account name for the server User.
3239 This has fewer security implications than the old approach.
3242 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
3243 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this

3257 *) Make PrintPath work generically instead of having one version
3258 strictly for OS/2. [Jim Jagielski, Brian Havard]
3260 *) Fix the recently introduced C header file checking: We now use the C
3261 pre-processor pass only (and no longer the complete compiler pass) to
3262 determine whether a C header file exists or not. Because only this way
3263 we're safe against inter-header dependencies (which caused horrible
3264 portability problems). The only drawback is that we now have a CPP
3265 configuration variable which has to be determined first (we do a similar
3266 approach as GNU Autoconf does here). When all fails the user still has
3267 the possibility to override it manually via APACI or src/Configuration.
3268 As a fallback for the header check itself we can directly check the
3269 existance of the file under /usr/include, too.

3312 *) Allow "Include" directives anywhere in the server config
3313 files (but not .htaccess files). [Ken Coar] PR#2727
3315 *) The proxy was refusing to serve CONNECT requests except to
3316 port 443 (https://) and 563 (snews://). The new AllowCONNECT
3317 directive allows the configuration of the ports to which a
3318 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
3320 *) mod_expires will now act on content that is not sent from a file
3321 on disk. Previously it would never add an Expires: header to
3322 any response that did not come from a file on disk; the only
3323 case where it still doesn't (and can't) add one for that type of
3324 content is if you are using a modification date based setting.
3325 [Marc Slemko, Paul Phillips <paulp@go2net.com>]
3327 *) Problems encountered during .htaccess parsing or CGI execution
3328 that lead to a "500 Server Error" condition now provide explanatory
3329 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
3332 *) Add NameWidth keyword to IndexOptions directive so that the
3333 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
3336 *) Recognize lowercase _and_ uppercase `uname' results under
3337 SCO OpenServer. [David Coelho <drc@ppt.com>]
3339 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
3340 a common problem of (mis-administrated?) IIS servers, make the apache
3341 proxy immune to these errors (and ignore the duplicates, but log
3342 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
3344 *) The <IfModule and <IfDefine block starting directives now only
3345 allow exactly one argument. Previously, the optional negation
3346 character '!' could be separated by whitespace without a syntax
3347 error being reported, albeit defeating the IfModule functionality
3348 (enclosed directives would ALWAYS be executed). By using the
3349 stricter syntax, these hard-to-track errors can be avoided.
3352 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
3353 cause the standalone FancyIndexing directive to logically OR
3354 into any existing IndexOptions settings rather than wiping
3355 them out. [Ken Coar]
3357 *) Changes in ftp proxy: make URL parsing simpler by using the
3359 + Add display of the "current directory" in cases where it's
3360 different from the supplied path (e.g., ftp://user@host/ lives
3361 in /home/user, not in /, therefore clicking on "../" in the
3362 starting directory might send us to /home/).
3363 + When ftp login fails, (esp. when a user name was part of the
3364 URL already), we now return [401 Unauthorized ] to allow the
3365 browser to pop up an authorization dialog. This makes passwords
3366 slightly less visible (they don't appear in the regular log files)
3367 and implements a functionality that other www proxy servers
3371 *) Triggered by the recent "Via:" header changes, the proxy module would
3372 dump core for replies with invalid headers (e.g., duplicate
3373 "HTTP/1.0 200 OK" lines). These errors are now logged and the
3374 core dump is avoided. Also, broken replies are not cached.
3375 [Martin Kraemer] PR#2914
3377 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
3378 plop gmon.out profile data for each child [Doug MacEachern]
3380 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
3381 config.status script to be immune against arguments with whitespaces.
3382 [Yves Arrouye <yves@apple.com>] PR#2866
3384 *) Replace the inlined information grabbing stuff for the configuration
3385 adjustment feature (no --without-confadjust) with calls to a new helper
3386 script `buildinfo.sh' which is both more flexible and already proofed to
3387 be more robust against platform differences. This mainly fixes the
3388 recently occured ``sed: command garbled: ...'' problems.
3389 [Ralf S. Engelschall] PR#2776, PR#2848

3406 *) Add the ability to do POST requests to the ab benchmarking tool.
3407 [Kurt Sussman <kls@best.com>] PR#2871
3409 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
3410 5 to 10 because there are some users out there who always have 5 to 8
3411 variables in one RewriteRule and had to patch mod_rewrite.h for every
3412 release. So 15 should be now more than enough, even for them. (I never
3413 needed more than 4 in my RewriteRules ;-)
3414 [Ralf S. Engelschall]
3416 *) Make the proxy generate and understand Via: headers
3419 *) Change the proxy to use tables instead of array_headers for
3420 the header lines. [Martin Kraemer]
3422 *) Make sure the config.status file is not overridden when just
3423 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
3425 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
3426 provide a way to trace API changes that add functionality but do
3427 not create a compatibility issue for precompiled modules, etc.
3428 See include/ap_mmn.h for more details. [Randy Terbush]
3430 *) Fix suexec installation under `make install root=xxx' situation.
3431 [Ralf S. Engelschall]
3433 *) Extend the output of the -V switch to include the paths of all
3434 compiled-in configuration files, if they were overridden at
3435 compile time, for least astonishment of the user.
3438 *) When READing a request in ExtendedStatus mode, the "old"
3439 vhost, request and client information is not displayed.
3442 *) STATUS is no longer available. Full status information now
3443 run-time configurable using the ExtendedStatus directive.
3446 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
3447 cpu time attacks) in header parsing. Add ap_overlap_tables(),
3448 a function which can be used to perform bulk update operations
3449 on tables in a more efficient manner. [Dean Gaudet]
3451 *) SECURITY: Added compile-time and configurable limits for
3452 various aspects of reading a client request to avoid some simple
3453 denial of service attacks, including limits on maximum request-line
3454 size (LimitRequestLine), number of header fields (LimitRequestFields),
3455 and size of any one header field (LimitRequestFieldsize). Also added
3456 a configurable directive LimitRequestBody for limiting the size of the
3457 request message body. [Roy Fielding]
3459 *) Make status module aware of DNS and logging states, even if
3460 STATUS not defined. [Jim Jagielski]
3462 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
3464 *) Enhance mod_speling so that CheckSpelling can be used in
3465 <Directory> containers and .htaccess files. [Ken Coar]
3467 *) API: new ap_custom_response() function for hooking into the
3468 ErrorDocument mechanism at runtime [Doug MacEachern]
3470 *) API: new ap_uuencode() function [Doug MacEachern]
3472 *) API: scan_script_header_err_core() now "public" and renamed
3473 ap_scan_script_header_err_core() [Doug MacEachern]
3475 *) The 'status' module will now show the process pid's and their
3476 state even without full STATUS accounting. [Jim Jagielski]
3478 *) Restore the client IP address to the error log messages, this
3479 was lost during the transition from 1.2 to 1.3. Add a new
3480 function ap_log_rerror() which takes a request_rec * and
3481 formats it appropriately. [Dean Gaudet] PR#2661
3483 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
3484 whitespace in input lines -- including within quoted strings.
3486 but leading and trailing whitespace should continue to be
3487 stripped [Martin Kraemer]
3489 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
3490 the ugly use of an env. variable and use command-line args for
3491 alternate $PATH. Make more like advanced 'type's as well.
3494 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
3495 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
3496 <alain.st-denis@ec.gc.ca>] PR#2736
3498 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
3500 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
3501 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
3502 directory was renamed to src/os/os2/ for consistency.
3503 [Brian Havard, Ralf S. Engelschall]
3505 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
3506 files (here modules) against other DSO files (here shared libraries).
3507 This is done by determining a subset of LIBS which can be safely used for
3508 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
3509 disabled for all platforms to avoid problems with this (experimental)
3510 rule. But we provide it now for those people how ran into problems and
3511 want to came out by forcing linking against DSOs.
3512 [Ralf S. Engelschall] PR#2587
3514 *) Fix suEXEC start message: Has to be of `notice' level to really get
3515 printed together with the standard startup message because the `notice'
3516 level is handled special inside ap_log_error() for startup messages.

3526 handling loop so that the connection can be properly closed with
3527 lingering_close, thus avoiding a potential TCP reset that would
3528 cause the client to miss the HTTP error response. [Roy Fielding]
3530 *) One more portability fix for APACI shadow tree support: Swap order of awk
3531 and sed in top-level configure script to avoid sed fails on some
3532 platforms (for instance SunOS 4.1.3 and NCR SysV) because of the

3594 the TRACE method. This allows apache to TRACE along a chain of proxies
3595 up to a predetermined depth. [Martin Kraemer]
3597 *) Fix SHARED_CORE rule: The CFLAGS_SHLIB variable is no longer doubled

3646 *) mod_mmap_static will no longer take action on requests unless at
3647 least one "mmapfile" directive is present in the configuration.
3648 This experimental module has to do some black magic to operate
3649 inside the current API and thus creates side-effects for other

3818 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
3820 *) Improve performance of directory listings (mod_autoindex) by comparing
3821 integer keys (last-modified and size) as integers rather than converting
3822 them to strings first. Also use a set of explicit byte tests rather
3823 than strcmp() to check for parent directory-ness of an entry. Oh, and
3824 make sure the parent directory (if displayed) is *always* listed first
3825 regardless of the sort key. Overall performance winnage should be good
3826 in CPU time, instruction cache, and memory usage, particularly for large
3827 directories. [Ken Coar]
3829 *) Add a tiny but useful goody to APACI's configure script: The generation
3830 of a config.status script (as GNU Autoconf does) which remembers the used
3831 configure command and hence can be used to restore the configuration by
3832 just re-running this script or for remembering the configuration between
3834 [Ralf S. Engelschall]
3836 *) Add httpd -t (test) option for running configuration syntax tests only.
3837 If something is broken it complains and exits with a return code
3838 non-equal to 0. This can be used manually by the user to check the Apache
3839 configuration after editing and is also automatically used by apachectl
3840 on (graceful) restart command to make sure Apache doesn't die on restarts
3841 because of a configuration which is now broken since the last (re)start.
3842 This way `apachectl restart' can be used inside cronjobs without having
3843 to expect Apache to be falling down. Additionally the httpd -t can be run
3844 via `apachectl configtest'.

3983 ap_spawn_child_err_buff became ap_bspawn_child
3984 spawn_child was obsoleted and moved to compat.h
3987 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
3988 programs: ap_spawn_child_err() is used and the Win32 case now uses
3989 CreateProcess() instead of a low-level execl() (which caused problems in
3990 the past under Win32).
3991 [Ralf S. Engelschall]
3993 *) A few cosmetics and trivial enhancements to APXS to make the
3994 generated Makefile more user friendly. [Ralf S. Engelschall]
3996 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
3997 was updated to use the normal apache error processing, thereby allowing
3998 proxy errors to be treated by ErrorDocument's as well. For this
3999 purpose, a new module-to-core communication variable "error-notes"
4000 was introduced; the proxy (and possibly other modules) communicates
4001 its error text using this variable. Its content is copied to a new
4002 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
4003 The old proxy special error routine ap_proxy_log_uerror()
4004 was replaced by regular ap_log_error() calls, many messages were made

4008 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
4011 *) Transform the configure message "You need root privileges for suEXEC"
4012 from a fatal error into a (more friendly) warning because the building
4013 ("make") of Apache we can allow, of course. Root privileges are needed
4014 only for the installation step ("make install"). So make sure the

4038 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often

4050 [Rick Ohnemus <rick@ecompcon.com>]
4052 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's

4071 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
4072 [Ben Laurie] PR#2238
4074 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
4075 library), so CGI handling has been changed to use Win32 native handles
4076 instead of C file descriptors.
4077 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
4079 *) The proxy cache would store an incorrect content-length in the cached
4080 file copy after a cache update. That resulted in repeated fetching
4081 of the original copy instead of using the cached copy.
4082 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
4084 *) The Makefiles assumed that DSO files are build via $(LD). This
4085 is broken for two reasons: First we never defined at least LD=ld
4086 somewhere to make sure this works (it was silently assumed that most Make
4087 provide a built-in LD definition - ARGL!) and second using the generic LD
4088 variable is not the truth. Instead a special variable named LD_SHLIB is
4089 reasonable because although "ld" is usually the default, the command for
4090 building DSO files can be "libtool" or even "cc" on some systems.
4091 [Ralf S. Engelschall]
4093 *) Replace the AddVersionPlatform directive with ServerTokens which
4094 provides for more control over the format of the Server:
4095 header line. SERVER_SUBVERSION is no longer supported;
4096 all module should use the ap_add_version_component()
4097 API function instead. [Jim Jagielski]
4099 *) Support for the NCR MP/RAS 3.0
4100 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
4102 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
4103 not retrieved in src/Configure and thus was not useable.
4104 [Ralf S. Engelschall]
4106 *) Various Makefile consistency cleanups:
4107 - make OSDIR also automatically be relative to src/ like INCDIR
4108 - SUBDIRS is now generated in src/Makefile only and not in
4109 Makefile.config because it is a local define for this location.
4110 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
4111 any Makefile but make sure that at least the "-K inline" is kept in
4113 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
4114 - updated the dependencies theirself
4115 - removed not existing SHLIB variable from "clean" targets
4116 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
4117 already exists and OBJS_PIC are also just plain objects and have not
4118 directly to do with "shared" things. The only difference is that they
4119 contain PIC. So OBJS_PIC is the more canonical name.
4120 - Updated the Makefile-dependency lines for OBJS_PIC
4121 - Removed the Makefile-dependency line in Configure to avoid double
4123 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
4124 of xxx.lo as GNU libtool does with its PIC objects
4125 - reduce local complexity in modules Makefile.tmpl by moving the last
4126 existing target "depend" to the generation section in Configure, too.
4127 - removed the historical $(SPACER) which was used in the past together
4128 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
4129 is no longer needed.
4130 - force the build and run of the gen_xxx programs under main/ as the
4131 first step before building the objects because it looks cleaner
4132 [Ralf S. Engelschall]
4134 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
4137 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
4140 *) WIN32: Don't force ISAPI headers to finish with \n.
4141 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
4143 *) When opening "configuration" files (like httpd.conf, htaccess
4144 and htpasswd), Apache will not allow them to be non-/dev/null
4145 device files. This closes a DoS hole. At the same time,
4146 we use ap_pfopen to open these files to handle timeouts.
4147 [Jim Jagielski, Martin Kraemer]
4149 *) Apache will now log the reason its httpd children exit if they exit
4150 due to an unexpected signal. (It requires a new porting define,
4151 SYS_SIGLIST, which if defined should point to a list of text
4152 descriptions of the signals available. See PORTING.) [Dean Gaudet]
4154 *) WIN32: chdir() doesn't make sense in a multithreaded environment
4155 like WIN32. Before, Win32 CGI's could have had sporadic failures
4156 if a chdir call from one thread was made between another chdir call
4157 and a spawn in another thread. So, for now don't chdir for CGI scripts
4158 in WIN32. The current CGI "spec" is unclear as to whether it's
4159 necessary. Long-term fix is to either serialize the chdir/spawn combo
4160 or use WIN32 native calls to spawn a process. This temp fix was
4161 necessary to remove this as a showstopper for 1.3's release.
4164 *) Cleanup the suEXEC support in APACI and make it more safe:
4165 1. Add big fat hint in INSTALL about risks and to read the
4166 htdocs/manual/suexec.html document before using the suexec-related
4168 2. Make sure the user has at least provided one --suexec-xxxx option
4169 (specifies suEXEC parameters) in addition to --enable-suexec option.
4170 If only --enable-suexec is given APACI stops with a hint to INSTALL
4171 and htdocs/manual/suexec.html documents.
4172 3. Provide two additional --suexec-xxxx options to make the suEXEC
4173 configuration complete (especially for package maintainers who else
4174 had to patch the source tree) by providing ways to configure minimal
4175 UID/GID and safe PATH, too.
4176 [Ralf S. Engelschall]
4178 *) Cleanup of the `configure --shadow' process:
4179 - make sure the configure script creates its temporary files in the
4180 shadow tree to avoid conflicts with parallel configure runs
4181 - removed unnecessary option "-r" from "rm" call for Makefiles
4182 - make sure the configure scripts creates the shadow-wrapper Makefile
4183 only when no shadow trees already exists
4184 - make sure "make distclean" removes the shadow-wrapper Makefile but only
4185 when no more shadow trees exists
4186 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
4187 as fast (in the past it needed 70sec, now it runs just 38sec)
4188 - make sure CVS does not complain about the created files
4189 Makefille.<gnutriple> and directories src.<gnutriple>
4190 [Ralf S. Engelschall]
4192 *) Added the ap_add_version_component() API routine and the
4193 AddVersionPlatform core directive. The first allows modules to
4194 declare themselves in the Server response header field value,
4195 augmenting the SERVER_SUBVERSION define in the Configuration file
4196 with run-time settings (more useful in a loadable-module environment).
4197 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
4198 into the server version string. [Ken Coar] PR#2056
4200 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
4203 *) Emit the "Accept-Range" header for the default handler.
4204 [Brian Behlendorf] PR#1464
4206 *) Add a note to httpd.conf-dist that apache will on some systems fail
4207 to start when the Group # is set to a negative or large positive value.
4210 *) Make sure the module execution order is correct even when some modules
4211 are loaded under runtime (`LoadModule') via the DSO mechanism:
4212 1. The list of loaded modules is now a dynamically allocated one
4213 and not the original statically list from modules.c
4214 2. The loaded modules are now correctly setup by LoadModule for
4215 later use by the AddModule command.
4216 3. When the DSO mechanism for modules is used APACI's `install'
4217 target now enables all created `LoadModule' lines per default because
4218 this is both already expected by the user _and_ needed to avoid
4219 confusion with the next point and reduces the Makefile.tmpl complexity
4220 4. When the DSO mechanism for modules is used, APACI's `install'
4221 target now additionally makes sure the module list is reconstructed
4222 via a complete `ClearModuleList+AddModule...' entry.
4223 5. The support tool `apxs' now also makes sure an AddModule command
4224 is added in addition to the LoadModule command.
4225 6. The modules.c generation was extended to now contain two
4226 comments to make sure no one is confused by the confusing terminology
4227 of loading/linking (we use load=link+load & link=activate instead of
4228 the obvious load=activate & link=link :-( )
4229 This way now there is no longer a difference under execution time between
4230 statically and dynamically linked modules.
4231 [Ralf S. Engelschall]
4233 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
4234 Big Symbol Renaming. [Ralf S. Engelschall]
4236 *) Add a comment to mod_example.c showing the format of a FLAG command
4239 *) Standardized the time format in mod_status to match that of other
4240 places in the code (e.g. DATE_GMT). PR#1551
4242 *) Fix handling of %Z in timefmt strings for those platforms with no time
4243 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
4246 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
4247 feature compatible with 'UseCanonicalName off' by changing
4248 r->server->server_hostname to ap_get_server_name(). And I changed some
4249 functions which use r->server->port to use ap_get_server_port() instead,
4250 because if there's no Port directive in the config r->server->port is 0.
4253 *) get/set_module_config are trivial enough to be better off inline. Worth
4254 1.5% performance boost. [Dean Gaudet]
4256 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
4257 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
4260 *) [BS2000 security] BS2000 needs an extra authentication to initialize
4261 the task environment to the unprivileged User id. Otherwise CGI scripts
4262 would have a way to gain super user access. [Martin Kraemer]
4264 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
4265 absolute path, only log base name of logging source as is done
4266 in unix. [Martin Kraemer]
4268 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
4269 the encoding type from the Accept-Encoding header (if it's there)
4270 and use it in the response, as that's probably what it'll be expecting.
4271 [Ronald.Tschalaer@psi.ch]
4273 *) Fix to mod_alias: translate_alias_redir is dealing with
4274 a URI, not a filename, so the check for drive letters for win32
4275 and emx is not necessary. [Dean Gaudet]
4277 *) WIN32: Allow .cmd as an executable extension.
4278 [Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146
4280 *) Make Apache header files, and some variables, C++ friendly.
4281 [Michael Anderson's <mka@redes.int.com.mx>]
4283 *) Child processes can now "signal" (by exiting with a status
4284 of APEXIT_CHILDFATAL) the parent process to abort and
4285 shutdown the server if the error in the child process was
4286 fatal enough. [Jim Jagielski]
4288 *) mod_autoindex's find_itme() was sensitive to MIME type case.
4289 [Jim Jagielski] PR#2112
4291 *) Make sure the referer_log and agent_log entries in the default httpd.conf
4292 file are also adjusted for the actual relative installation paths.

4295 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
4297 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
4300 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
4301 Additionally the checks for finding the vendor DSO library were moved
4302 from mod_so.c to Configure because first it needs $PLAT etc. and second
4303 mod_so already uses an abstraction layer and does not fiddle with the
4304 vendor functions itself.
4305 [Jens-Uwe Mager, Ralf S. Engelschall]
4307 *) PORT: Some optimization defines for NetBSD
4308 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
4310 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
4311 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
4313 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
4314 AIX variants should work fine, too. Even AIX 3.x should work). This is
4315 accomplished by using the free DSO emulation code from Jens-Uwe Mager
4316 which we put into a os/unix/os-dso-aix.c file.
4317 [Ralf S. Engelschall]
4319 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
4320 that we should use NET_SIZE_T == int but the include files force size_t.
4321 [Ralf S. Engelschall]
4323 *) Fix two bugs in select() handling in http_main.c.
4326 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
4327 is unset (as it is in situations like timeouts) where it is unclear
4328 whether errno is set or not. [Martin Kraemer]
4330 *) Just having APACI's localstatedir is too general and not enough for most
4331 of the systems. 1.3b6 again required manual APACI patches by package
4332 maintainers from RedHat and FreeBSD because for their filesystem layout a
4333 little bit more flexibility in configuring the paths is needed. Hence we
4334 provide three additional configure options (--runtimedir, --logfiledir,
4335 --proxycachedir) which now can be used for more granular adjustments if
4336 --localstatedir is not enough to fit the particular needs. As a nice
4337 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
4338 [Ralf S. Engelschall]
4340 *) Make the install root for "make install" in APACI's Makefile overrideable
4341 by package authors. This way we are even more friendly to package
4342 maintainers (especially Debian and RedHat) who build for the real prefix
4343 via "configure --prefix=/<real>" but use a different local prefix via
4344 "make root=/tmp/apache install" for rolling the package without bristling
4345 the target location on their system.
4346 [Ralf S. Engelschall]
4348 *) Workaround sed limitations in APACI's configure script by now
4349 substituting in chunks of 50 commands (because for instance HPUX's vendor
4350 sed has a limit of max. 98 commands)
4351 [Ralf S. Engelschall] PR#2136
4353 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
4354 [Ralf S. Engelschall] PR#2140
4356 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
4357 RENAMING process because they are defined as pre-processor macros instead
4358 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
4359 [Ralf S. Engelschall]
4361 *) Workaround braindead AWK's when generating ap_config.h: The split() and
4362 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
4363 [Ralf S. Engelschall] PR#2139
4365 *) Various bugfixes and cleanups for the APACI configure script:
4366 o fix IFS handling for _nested_ situation
4367 o fix Perl interpreter search: take first one found instead of last one
4368 o fix DSO consistency check
4369 o print error messages to stderr instead of stdout
4370 o add install-quiet for --shadow situation to Makefile stub
4371 o reduce complexity by avoiding sed-hacks for rule and module list loops
4372 [Ralf S. Engelschall]
4374 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
4376 *) Make sure the input field separator (IFS) shell variable is explicitly
4377 initialized correctly before _every_ `for' loop and also restored after
4378 the loops. [Ralf S. Engelschall]
4380 *) Make sure that "make install" doesn't overwrite the `mime.types' and
4381 `magic' files from an existing Apache installation. Because people often
4382 customize these for own MIME and content types.
4383 [Ralf S. Engelschall]
4385 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
4386 [Peter Galbavy, Ralf S. Engelschall] PR#2109
4388 *) Fix the path to the ScoreBoardFile in the install-config target, too.
4389 [Ralf S. Engelschall] PR#2105
4391 *) Let "configure" clear out the users parameters (provided as shell
4392 variables) to avoid side-effects in "src/Configure" when the user
4393 exported them (which is not needed, but some users do it).
4394 [Ralf S. Engelschall] PR#2101
4396 *) Provide backward compatibility from some old src/Configuration.tmpl
4397 parameter names to the canonical Autoconf-style shell variable names. For
4398 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
4399 but a hint message is displayed. [Ralf S. Engelschall]
4401 *) Make sure that "make install" doesn't overwrite the DocumentRoot and
4402 CGI scripts from an existing Apache installation.
4403 [Ralf S. Engelschall, Jim Jagielski] PR#2084
4405 *) Make `configure --compat' more "compatible" by first
4406 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
4407 second by making sure the "avoid-bristling-suffix" /apache is not
4408 appended to sysconfdir, datadir, localstatedir and includedir when
4409 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]
4411 *) NeXT required strdup() in support/logresolve.c
4412 [Francisco Tomei <fatomei@sandburg.unm.edu>] PR#2082
4414 *) AIX required sys/select.h in support/ab.c
4415 [Jens Schleusener <Jens.Schleusener@dlr.de>] PR#2081
4417 *) Fix the path to the MimeMagicFile in the install-config target, too.
4418 [Ralf S. Engelschall] PR#2089
4420 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
4422 *) If you start apache with the -S command line option it will dump
4423 out the parsed vhost settings. This is useful for folks trying
4424 to figure out what is wrong with their vhost configuration.
4425 (Other dumps may be added in the future.) [Dean Gaudet]
4427 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
4428 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
4431 *) Because /usr/local/apache is the default prefix the ``configure
4432 --compat'' option no longer has to set prefix, again. This way the
4433 --compat option honors a leading --prefix option. [Lars Eilebrecht]
4435 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
4436 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
4437 to avoid "discard const" warnings. [Ralf S. Engelschall]
4439 *) If a specific handler is set for a file yet the request still
4440 ends up being handled by the default handler, log an error
4441 message before handling it. This catches things such as trying
4442 to use SSIs without mod_include enabled. [Marc Slemko]
4444 *) Fix error logging for the startup case where ap_log_error() still uses
4445 stderr as the target. Now the default log level is honored here, too.
4446 [Ralf S. Engelschall]
4448 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
4449 long" errors when generating the MODULES entry for src/Makefile
4450 [Ben Hyde, Ralf S. Engelschall]
4452 *) Make sure src/Configure doesn't complain about the old directory
4453 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
4455 Changes with Apache 1.3b6
4457 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
4459 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
4460 interface via the similar but proprietary HP/UX shl_xxx-style system
4461 calls. [Ralf S. Engelschall]
4463 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
4464 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
4465 Make. [Ralf S. Engelschall]
4467 *) ++++ THE BIG SYMBOL RENAMING ++++
4468 To avoid symbol clashes with third-party code compiled into the server,
4469 we globally applied the prefix "ap_" to the following classes of
4471 - Apache provided general functions (e.g., ap_cpystrn)
4472 - Public API functions (e.g., palloc, bgets)
4473 - Private functions which we can't make static (because of
4474 cross-object usage) but should be (e.g., new_connection)
4475 For backward source compatibility a new header file named compat.h was
4476 created which provides defines for the old symbol names and can be used
4477 by third-party module authors.
4480 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
4481 problem under SVR4 is that there is no command flag to force the linker
4482 to export the global symbols of the httpd executable therewith they are
4483 available to the DSO's. Instead of problematic hacks like creating a
4484 dummy.so file (containing dummy references to all global symbols) the
4485 httpd binary is linked against, we use a clean trick stolen from Perl 5:
4486 Placing the Apache core code itself into a DSO library named libhttpd.so.
4487 This way the global symbols _HAVE_ to be exported and thus are available
4488 to any manually loaded DSO's under runtime. To reduce the impact to the
4489 user to null we go even further and create a stub httpd executable which
4490 automatically keeps track of the DSO library loading itself and thus
4491 hides the complete mechanism from the user. Although the generation of
4492 this DSO library is automatically triggered for platforms which
4493 essentially need it (mostly all SVR4-derivates) it can be also enabled
4494 manually via the Rule SHARED_CORE. This can be interesting in the future
4495 where we perhaps exploit this libhttpd.so mechanism for providing nifty
4496 features like graceful upgrades, or whatever.
4497 [Ralf S. Engelschall, Martin Kraemer]
4499 *) Build the libraries before building the rest of the tools. [Ben Hyde]
4501 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
4502 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
4503 conventions while "clean" removes only stuff created by "all" targets,
4504 "distclean" additionally removes the stuff from the configuration
4505 process. This way "make distclean" (hence the name) provides a fresh
4506 source tree as it was for distribution.
4507 [Ralf S. Engelschall]
4509 *) Allow top-level (APACI) Makefile to break on build errors
4510 the same way the src/ subtree Makefiles breaks on them by replacing the
4511 initial APACI sed-subdir-display-kludge with a more clean
4512 variable-passing-solution: variable SDP can optionally hold the subdir
4513 prefix which is consistently used for displaying the subdir movement.
4514 This way even the top-level Makefile can stop correctly on errors as the
4515 user expects. [Ralf S. Engelschall]
4517 *) Fixed ordering of argument checks for RewriteBase directive.
4518 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
4520 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
4521 indicating that a module is being compiled for dynamic loading. Also
4522 remove #define IS_MODULE from modules and add SHARED_MODULE define
4523 to the mak/dsp files. [Alexei Kosut]
4525 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
4526 since we are now logging APLOG_WARNING by default. [Roy Fielding]
4528 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
4530 *) Add documentation file and src/Configuration.tmpl entry for the
4531 experimental mod_mmap_static module. Because although it is and marked as
4532 an experimental one it is distributed and thus should be documented and
4533 prepared for configuration the same way as all others modules.
4534 [Ralf S. Engelschall]
4536 *) Add query (-q) option to apxs support tool to be able to manually query
4537 specific settings from apxs. This is needed for instance when you
4538 manually want to access Apache's header files and you need to assemble
4539 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
4540 [Ralf S. Engelschall]
4542 *) Now src/Configure uses a fallback strategy for the shared object support
4543 on platforms where no explicit information is available: If a Perl
4544 installation exists we ask it about its shared object support and if it's
4545 the dlopen-style one we shamelessly guess the compiler and linker flags
4546 for creating shared objects from Perls knowledge. Of course, the user is
4547 warning about what we are doing and informed that he should send us
4548 the guessed flags when they work. [Ralf S. Engelschall]
4550 *) Provide APACI --without-support option to be able to disable the build
4551 and installation of the support tools from the src/support/ area.
4552 Although its useful to have these installed per default we should provide
4553 a way to compile and install without them for backward-compatibility.
4554 [Ralf S. Engelschall]
4556 *) Add of the new APache eXtenSion (apxs) support tool for building and
4557 installing modules into an _already installed_ Apache package through the
4558 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
4559 this approach actually doesn't need the Apache source tree. The
4560 (APACI-installed) server package is enough, because this now includes the
4561 Apache C header files (PREFIX/include) and the new APXS tool
4562 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
4563 module authors to build their Apache modules _OUTSIDE_ the Apache source
4564 tree while avoiding them to fiddle around with the totally platform
4565 dependend way of compiling DSO files. The tool supports all ranges of
4566 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
4567 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
4568 on-the-fly generate a minimalistic Makefile and sample module for the
4569 first step to provide both a quick success event and to demonstrate the
4570 APXS mechanism to module authors. [Ralf S. Engelschall]
4572 *) Fix core dumps in use of CONNECT in proxy.
4573 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
4575 *) Modify the log directives in httpd.conf-dist files to use CustomLog
4576 so that users have examples of how CustomLog can be used.
4579 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
4580 the Apache distribution tree. Until Apache 1.3 there was no real
4581 out-of-the-box batch-capable build and installation procedure for the
4582 complete Apache package. This is now provided by a top-level "configure"
4583 script and a corresponding top-level "Makefile.tmpl" file. The goal is
4584 to provide a GNU Autoconf-style frontend which is capable to both drive
4585 the old src/Configure stuff in batch and additionally installs the
4586 package with a GNU-conforming directory layout. Any options from the old
4587 configuration scheme are available plus a lot of new options for flexibly
4588 customizing Apache. [Ralf S. Engelschall]
4590 *) The floating point ap_snprintf code wasn't threadsafe.
4591 Had to remove the HAVE_CVT macro in order to do threadsafe
4592 calling of the ?cvt() floating point routines. [Dean Gaudet]
4594 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
4596 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
4597 [Jim Jagielski] PR#1901
4599 *) BUG: Configure was using TCC and CC inconsistently. Make sure
4600 Configure knows which CC we are using. [Jim Jagielski]
4602 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
4603 was defined in a parent directory. [Lars Eilebrecht]
4605 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
4606 a generic printf-style routine that can call arbitrary output
4607 routines. Use this to replace http_bprintf.c. Add new routines
4608 psprintf(), pvsprintf() which allocate the exact amount of memory
4609 required for a string from a pool. Use psprintf() to clean up
4610 various bits of code which used ap_snprintf()/pstrdup().
4613 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
4614 ap_snprintf() has different semantics and formatting codes than
4615 snprintf(). [Dean Gaudet]
4617 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
4618 is necessary on at least Solaris where the /etc/rc?.d scripts
4619 are run with these signals ignored, and "SIG_IGN" settings are
4620 maintained across exec().
4621 [Rein Tollevik <reint@sys.sol.no>] PR#2009
4623 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
4624 used instead of lstat() and thus this flag didn't work as expected.
4625 [Rein Tollevik <reint@sys.sol.no>] PR#2010
4627 *) Fix the proxy pass-through feature of mod_rewrite for the case of
4628 existing QUERY_STRING now that mod_proxy was recently changed because of
4629 the new URL parsing stuff. [Ralf S. Engelschall]
4631 *) A few changes to scoreboard definitions which helps gcc generate
4632 better code. [Dean Gaudet]
4634 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
4635 be a signed bitfield. So mark a few bitfields as signed to
4636 ensure correct code. [Dean Gaudet]
4638 *) The default for HostnameLookups was changed to Off, but there
4639 was a problem and it wasn't taking effect. [Dean Gaudet]
4641 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
4644 *) After a SIGHUP the listening sockets in the parent weren't
4645 properly marked for closure on fork().
4646 [Jürgen Keil <jk@tools.de>] PR#2000
4648 *) Allow %2F in two situations: 1) it is in the query part of the URI,
4649 therefore not exposed to %2F -> '/' translations and 2) the request
4650 is a proxy request, so we're not dealing with a local resource anyway.
4651 Without this, the proxy would fail to work for any URL's with
4652 %2f in them (occurs quite often in
4653 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
4655 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
4657 *) Make the shared object compilation command more portable by avoiding
4658 the direct combination of `-c' & `-o' which is not honored by some
4659 compilers like UnixWare's cc. [Ralf S. Engelschall]
4661 *) WIN32: the proxy was creating filenames missing the last four
4662 characters. While this normally doesn't stop anything from
4663 working, it can result in extra collisions.
4664 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
4666 *) Now mod_proxy uses the response string (in addition to the response status
4667 code) from the already used FTP SIZE command to setup the Content-Length
4668 header if available. [Ralf S. Engelschall] PR#1183
4670 *) Reanimated the (still undocumented) proxy receive buffer size directive:
4671 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
4672 name was really too generic, added documentation for this directive to
4673 the mod_proxy.html and corrected the hyperlink to it in the
4674 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
4676 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
4677 faster [Martin Kraemer]
4679 *) Make Configure die when you give it an unknown command switch.
4682 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
4683 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
4684 and per default compiled support programs have manual pages - just to
4685 document our stuff a little bit more and to be able to do really
4686 Unix-like installations ;-) [Ralf S. Engelschall]
4688 *) Major cleanups to the Configure script to make it and its generated
4689 Makefiles again readable and maintainable: add SRCDIR option, removed
4690 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
4691 generated sections, consequently added Makefile headers with inheritance
4692 information, added subdir movement messages for easier following where
4693 the build process currently stays (more verbose then standard Make, less
4694 verbose than GNU make), same style to comments in the Configure script,
4695 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
4697 *) Add the new ApacheBench program "ab" to src/support/: This is derived
4698 from the ZeusBench benchmarking program and can be used to determine the
4699 response performance of an Apache installation. This version is
4700 officially licensed with Zeus Technology, Ltd. See the license agreement
4701 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
4702 [Ralf S. Engelschall]
4704 *) API: Various core functions that are definately not part of the API
4705 have been made static, and a few have been marked API_EXPORT. Still
4706 more have been marked CORE_EXPORT and are not intended for general
4707 use by modules. [Doug MacEachern, Dean Gaudet]
4709 *) mod_proxy was not clearing the Proxy-Connection header from
4710 requests; now it does. This did not violate any spec, however
4711 causes poor interactions when you are talking to remote proxies.
4712 [Marc Slemko] PR#1741
4714 *) Various cleanups to the command line interface and manual pages.
4715 [Ralf S. Engelschall]
4717 *) cfg_getline() was not properly handling lines that did not end
4718 with a line termination character. [Marc Slemko] PR#1869, 1909
4720 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
4722 *) Clean up some undocumented behavior of mod_setenvif related to
4723 "merging" two SetEnvIf directives when they match the same header
4724 and regex. Document that mod_setenvif will perform comparisons in
4725 the order they appear in the config file. Optimize mod_setenvif by
4726 doing more work at config time rather than at runtime.
4729 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
4730 to allow for modules to overrule them and to reduce redefinition
4731 warnings [Jim Jagielski]
4733 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
4736 *) Making the hard-coded cross-module function call mime_find_ct() (from
4737 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
4738 checking is really called even for proxy requests except for URLs with
4739 HTTP schemes (because there we can optimize by not running the type
4740 checking hooks due to the fact that the proxy gets the MIME Content-type
4741 from the remote host later). This change cleans up mod_mime by removing
4742 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
4743 especially unbundles mod_proxy and mod_mime. This way they both now can
4744 be compiled as shared objects and are no longer tied together.
4745 [Ralf S. Engelschall]
4747 *) util.c cleanup and speedup. [Dean Gaudet]
4749 *) API: Clarification, pstrndup() will always copy n bytes of the source
4750 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
4752 *) Mark module command_rec and handler_rec structures const so that they
4753 end up in the read-only data section (and are friendlier to systems
4754 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
4756 *) Add check to the "Port" directive to make sure the specified
4757 port is in the appropriate range. [Ben Hyde]
4759 *) Performance improvements to invoke_handler().
4760 [Dmitry Khrustalev <dima@bog.msu.su>]
4762 *) Added support for building shared objects even for library-style modules
4763 (which are built from more than one object file). This now provides the
4764 ability to build mod_proxy as a shared object module. Additionally
4765 modules like mod_example are now also supported for shared object
4766 building because the generated Makefiles now no longer assume there is at
4767 least one statically linked module. [Ralf S. Engelschall]
4769 *) API: Clarify usage of content_type, handler, content_encoding,
4770 content_language and content_languages fields in request_rec. They
4771 must always be lowercased; and the strings pointed to shouldn't
4772 be modified (you must copy them to modify them). Fix a few bugs
4773 related to this. [Dean Gaudet]
4775 *) API: Clarification: except for RAW_ARGS, all command handlers can
4776 treat the char * parameters as permanent, and modifiable. There
4777 is no need to pstrdup() them. Clean up some needless pstrdup().
4780 *) Now mod_so keeps track of which module shared objects with which names
4781 are loaded and thus avoids multiple loading and unloading and irritating
4782 error_log messages. [Ralf S. Engelschall]
4784 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
4785 environment variable in the apache core. But that tweaking interferes
4786 with mod_setenv. So don't tweak if the user has specified an explicit
4787 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888

4797 *) Various improvements to the configuration and build support for compiling
4798 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
4799 OSF1 support with GCC and vendor compilers was added. This way shared
4800 object support is now provided out-of-the-box for FreeBSD, Linux,
4801 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!

4804 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
4805 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
4806 and USE_OS2_SCOREBOARD. [Dean Gaudet]
4808 *) Fix one more special locking problem for RewriteMap programs in
4809 mod_rewrite: According to the documentation of flock(), "Locks are on
4810 files, not file descriptors. That is, file descriptors duplicated
4811 through dup(2) or fork(2) do not result in multiple instances of a lock,
4812 but rather multiple references to a single lock. If a process holding a
4813 lock on a file forks and the child explicitly unlocks the file, the
4814 parent will lose its lock.". To overcome this we have to make sure the
4815 RewriteLock file is opened _AFTER_ the childs were spawned which is now
4816 the case by opening it in the child_init instead of the module_init API
4817 hook. [Ralf S. Engelschall] PR#1029
4819 *) Change to Location and LocationMatch semantics. LocationMatch no
4820 longer lets a single slash match multiple adjacent slashes in the
4821 URL. This change is for consistency with RewriteRule and
4822 AliasMatch. Multiple slashes have meaning in URLs that they do
4823 not have in (some) filesystems. Location on the other hand can
4824 be considered a shorthand for a more complicated regex, and it
4825 does match multiple slashes with a single slash -- which is
4826 also consistent with the Alias directive.

4829 *) Fix bug with mod_mime_magic causing certain files, including files
4830 of length 0, to result in no response from the server.
4833 *) The Configure script now generates src/include/ap_config.h which
4834 contains the set of defines used when Apache is compiled on a platform.
4835 This file can then be included by external modules before including
4836 any Apache header files in case they are being built separately from
4837 Apache. Along with this change, a couple of minor changes were
4838 made to make Apache's #defines coexist peacefully with any autoconf
4839 defines an external module might have. [Rasmus Lerdorf]
4841 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
4842 but without any RewriteXXXXX directives. Here mod_rewrite is given no
4843 chance by the API to initialize its per-server configuration and thus
4844 receives the wrong one from the main server. This is now avoided by
4845 remembering the server together with the config structure while
4846 configuring and later assuming there is no config when we see a
4847 difference between the remembered server and the one calling us.
4848 [Ralf S. Engelschall] PR#1790
4850 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
4851 is automatically disabled under configure time when the dbm_xxx functions
4852 are not available. Second, two heavy source code errors in the DBM
4853 support code were fixed. This makes DBM RewriteMap's usable again after
4854 a long time of brokenness. [Ralf S. Engelschall] PR#1696
4856 *) Now all configuration files support Unix-style line-continuation via
4857 the trailing backslash ("\") character. This enables us to write down
4858 complex or just very long directives in a more readable way. The
4859 backslash character has to be really the last character before the
4860 newline and it has not been prefixed by another (escaping) backslash.

4875 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
4876 depending on the rev of Solaris and what mixture of modules
4877 are in use. So it has been disabled, and Solaris is back to
4878 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
4879 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
4880 up static content only servers. Or it may fail unpredictably.

4883 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
4886 *) API: Rewrite of absoluteURI handling, and in particular how
4887 absoluteURIs match vhosts. Unless a request is a proxy request, a
4888 "http://host" url is treated as if a similar "Host:" header had been
4889 supplied. This change was made to support future HTTP/1.x protocols
4890 which may require clients to send absoluteURIs for all requests.
4892 In order to achieve this change subtle changes were made to the API. In a
4893 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
4894 that the unmodified uri can be retrieved easily. r->proxyreq is not set
4895 by the core, modules must set it during the post_read_request or
4896 translate_names phase.
4898 Plus changes to the virtualhost test suite for absoluteURI testing.
4900 This fixes several bugs with the proxy proxying requests to vhosts
4901 managed by the same httpd.
4904 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
4905 code from mod_rewrite. The vhost matching is now performed by a
4906 globally available function matches_request_vhost(). [Dean Gaudet]

4922 *) API: A new source module main/util_uri.c; It contains a routine
4923 parse_uri_components() and friends which breaks a URI into its component
4924 parts. These parts are stored in a uri_components structure called
4925 parsed_uri within each request_rec, and are available to all modules.
4926 Additionally, an unparse routine is supplied which re-assembles the URI
4927 components back to an URI, optionally hiding the username:password@ part
4928 from ftp proxy requests, and other useful routines. Within the structure,
4929 you find on a ready-for-use basis:
4930 scheme; /* scheme ("http"/"ftp"/...) */
4931 hostinfo; /* combined [user[:password]@]host[:port] */
4932 user; /* user name, as in http://user:passwd@host:port/ */
4933 password; /* password, as in http://user:passwd@host:port/ */
4934 hostname; /* hostname from URI (or from Host: header) */
4935 port_str; /* port string (integer representation is in "port") */
4936 path; /* the request path (or "/" if only scheme://host was given) */
4937 query; /* Everything after a '?' in the path, if present */
4938 fragment; /* Trailing "#fragment" string, if present */
4939 This is meant to serve as the platform for *BIG* savings in
4940 code complexity for the proxy module (and maybe the vhost logic).
4943 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
4944 ${map:key}) available for all location where a string is created in
4945 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
4946 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
4947 possible expansions are consequently usable at all string creation
4948 locations. [Ralf S. Engelschall]
4950 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
4951 and not 1) and the per-virtual-server merging of directives. Now all
4952 directives except `RewriteEngine' and `RewriteOption' are either
4953 completely overridden (default) or completely inherited (when
4954 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

4963 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
4964 (like SunOS and FreeBSD) which don't accept the locking of pipes
4965 directly. A new directive RewriteLock is introduced which can be used to
4966 setup a separate locking file which then is used for synchronization.

4984 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
4985 type but with a special post-processing for the looked-up value: It
4986 parses it into alternatives according to `|' chars and then only one
4987 particular alternative is chosen randomly (this is an essential
4988 functionality needed for balancing between backend-servers when using
4989 Apache as a Reverse Proxy. The looked up value here is a list of
4990 servers). Second, `int' with the built-in maps named `tolower' and
4991 `toupper' which can be used to map URL parts to a fixed case (this is an
4992 essential feature to fix the case of server names when doing mass
4993 virtual-hosting with the help of mod_rewrite instead of using
4994 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
4995 Jay Soffian <jay@cimedia.com>] PR#1631
4997 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
4998 This directive lets Apache adjust the URL in Location-headers on HTTP
4999 redirect responses sent by the remote server. This way the virtually
5000 mapped area is no longer left on redirects and thus by-passed which is
5001 especially essential when running Apache as a reverse proxy.

5116 now ignores a leading x- when comparing encodings. It also
5117 preserves the encoding the client requests (for example if
5118 it requests x-gzip, then Apache will respond with x-gzip
5119 in the Content-Encoding header).

5149 *) Yet another rearrangement of the source tree.. now all the common
5150 header files are in the src/include directory. The -Imain -Iap
5151 references in Makefiles have been changed to the simpler -Iinclude
5152 instead. In addition to simplifying the build a little bit, this
5153 also makes it clear when a module is referencing something in a
5154 other than kosher manner (e.g., the proxy including mod_mime.h).
5155 Module-private header files (the proxy, mod_mime, the regex library,
5156 and mod_rewrite) have not been moved to src/include; nor have
5157 the OS-abstraction files. [Ken Coar]

5164 MAKE_TABLE_PROFILE which can help discover make_table()
5165 calls that use too small an initial guess, see alloc.c.

5169 server setting inside vhosts (only an issue when you have no
5170 <Directory> or other section containing an Options that affects
5171 a request). Options +foo or -foo in the main_server wouldn't

5186 *) mod_unique_id was erroneously generating a second unique id when
5187 an internal redirect occured. Such redirects occur, for example,
5188 when processing a DirectoryIndex match. [Dean Gaudet]
5190 *) API: table_add, table_merge, and table_set include implicit pstrdup()
5191 of the key and value. But in many cases this is not required
5192 because the key/value is a constant, or the value has been built
5193 by pstrcat() or other similar means. New routines table_addn,
5194 table_mergen, and table_setn have been added to the API, these
5195 routines do not pstrdup() their arguments. The core code and
5196 standard modules were changed to take advantage of these routines.
5197 The resulting server is up to 20% faster in some situations.
5199 Note that it is easy to get code subtly wrong if you pass a key/value
5200 which is in a pool other than the pool of the table. The only
5201 safe thing to do is to pass key/values which are in the pool of
5202 the table, or in one of the ancestors of the pool of the table.
5203 i.e. if the table is part of a subrequest, a value from the main
5204 request's pool is OK since the subrequest pool is a sub_pool of the
5205 main request's pool (and therefore has a lifespan at most as long as
5206 the main pool). There is debugging code which can detect improper
5207 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
5208 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
5210 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
5211 which don't exist on disk more gracefully; handles vhosts properly.
5212 Update documentation to reflect the code -- if there's no
5213 MimeMagicFile directive then the module is not enabled.
5216 *) PORT: Some older *nix dialects cannot automatically start scripts
5217 which begin with a #! interpreter line (the shell starts the scripts
5218 appropriately on these platforms). Apache now supports starting of
5219 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.

5223 *) API: "typedef array_header table" removed from alloc.h, folks should
5224 have been writing to use table as if it were an opaque type, but even
5225 some standard modules got this wrong. By changing the definition
5226 to "typedef struct table table" module authors will receive compile
5227 time warnings that they're doing the wrong thing. This change
5228 facilitates future changes with more sophisticated table
5229 structures. Specifically, module authors should be using table_elts()
5230 to get access to an array_header * for the table. [Dean Gaudet]
5232 *) API: Renamed new_connection() to avoid namespace collision with LDAP

5238 *) For clarity the following compile time definition was changed:
5240 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
5242 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
5243 and not be a general notice that the OS has mmap(). Now the
5244 HAVE_MMAP/SHMGET #defines strictly are informational that the
5245 OS has that method of shared memory; the type to use for
5246 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
5247 and USE_SHMGET_SCOREBOARD). This allows outside modules to
5248 determine if shared memory is available and allows Apache
5249 to determine the best method to use for the scoreboard.

5286 *) Improve the warning message generated when a client drops the
5287 connection (hits stop button, etc.) during a send. [Roy Fielding]
5289 *) Defining GPROF will disable profiling in the parent and enable it
5290 in the children. If you're profiling under Linux this is pretty much
5291 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
5293 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.
5296 *) The NeXT cc (which is gcc hacked up) doesn't appear to support some
5297 gcc functionality. Work around it.
5298 [Keith Severson <keith@sssd.navy.mil>] PR#1613
5300 *) Some linkers complain when .o files contain no functions.
5301 [Keith Severson <keith@sssd.navy.mil>] PR#1614
5303 *) Some const declarations in mod_imap.c that were added for debugging
5304 purposes caused some compilers heartburn without adding any
5305 significant value, so they've been removed. [Ken Coar]
5307 *) The src/main/*.h header files have had #ifndef wrappers added to
5308 insulate them against duplicate calls if they get included through
5309 multiple paths (e.g., in .c files as well as other .h files).
5312 *) The libap routines now have a header file for their prototypes,
5313 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
5315 *) mod_autoindex with a plaintext header file would emit the <PRE>
5316 start-tag before the HTML preamble, rather than after the preamble
5317 but before the header file contents. [John Van Essen <jve@gamers.org>]
5320 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
5321 only an issue on systems without a MAXDNAME define or where
5322 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
5324 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
5325 is used to read various types of files such as htaccess and
5326 htpasswd files. [Marc Slemko]
5328 *) SECURITY: Ensure that the buffer returned by ht_time is always
5329 properly null terminated. [Marc Slemko]
5331 *) The "Connection" header could be sent back with multiple "close"
5332 tokens. Not an error, but a waste.
5333 [Ronald.Tschalaer@psi.ch] PR#1683
5335 *) mod_rewrite's RewriteLog should behave like mod_log_config, it

5338 *) "basic" auth needs a case-insensitive comparison.
5339 [Ronald.Tschalaer@psi.ch] PR#1666
5341 *) For maximum portability, the environment passed to CGIs should
5342 only contain variables whose names match the regex
5343 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
5344 underscores over any character outside the regex. This
5345 affects HTTP_* variables, in a way that should be backward
5346 compatible for all the standard headers; and affects variables
5347 set with SetEnv/BrowserMatch and similar directives.
5350 *) mod_speling returned incorrect HREF's when an ambigous match

5386 *) SECURITY: Numerous changes to mod_imap in a general cleanup
5387 including fixing a possible buffer overflow. [Dean Gaudet]

5390 (connections are not dropped). Code can handle graceful restarts
5391 (but there is as yet no way to signal this to Apache). Various
5392 other cleanups. [Paul Sutton]
5394 *) The aplog_error changes specific to 1.3 introduced a buffer
5395 overrun in the (now legacy) log_printf function. Fixed.
5398 *) mod_digest didn't properly deal with proxy authentication. It
5399 also lacked a case-insensitive comparision of the "Digest"

5434 [Ben Reser <breser@regnow.com>] PR#1366
5436 *) The bputc() macro was not properly integrated with the chunking
5437 code; in many cases modules using bputc() could cause completely
5438 bogus chunked output. (Typically this will show up as problems
5439 with Internet Explorer 4.0 reading a page, but other browsers
5440 having no problem.) [Dean Gaudet]
5442 *) Create LARGE_WRITE_THRESHOLD define which determines how many
5443 bytes have to be supplied to bwrite() before it will consider
5444 doing a writev() to assemble multiple buffers in one system
5445 call. This is critical for modules such as mod_include,
5446 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
5447 strings in some cases. The result would be extra effort
5448 setting up writev(), and in many cases extra effort building
5449 chunks. The default is 31, it can be overriden at compile
5452 *) Move the gid switching code into the child so that log files
5453 and pid files are opened with the root gid.

5464 *) ap_slack() moved out of main/util.c into ap/ap_slack.c as part of
5465 the libap consolidation work. [Ken Coar]

5559 This turns out to be a bug in Winsock - select() doesn't always

5562 *) Directives owned by http_core can now use the new check_cmd_context()
5563 routine to ensure that they're not being used within a container

5566 *) PORT: Recent changes made it necessary to add explicit prototype
5567 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
5569 *) It was necessary to distinguish between resources which are
5570 allocated in the parent, for cleanup in the parent, and resources
5571 which are allocated in each child, for cleanup in each child.
5572 A new pool was created which is passed to the module child_init
5573 and child_exit functions; modules are free to register per-child
5574 cleanups there. This fixes a bug with reliable piped logs.
5577 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
5578 unless it was also doing FancyIndexes, but it displayed the
5579 HeaderName file at the top under all circumstances. It now shows
5580 the ReadmeName file for simple indices, too, as it should.
5583 *) http_core was mmap()ing even in cases where it wasn't going to
5584 read the file. [Ben Hyde <bhyde@gensym.com>]
5586 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
5587 Now the rewriting engine (the heart of mod_rewrite) is organized more
5588 straight-forward, first time well documented and reduced to the really
5589 essential parts. All redundant cases were stripped off and processing now
5590 is the same for both per-server and per-directory context with only a
5591 minimum difference (the prefix stripping in per-dir context). As a
5592 side-effect some subtle restrictions and two recently discovered problems
5593 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
5594 context and restrictions on the substitution URL on redirects.
5595 Additionally some minor source cleanups were done.

5752 *) TestCompile was not passing $LIBS [Dean Gaudet]
5754 *) Makefile.tmpl was not using $CFLAGS in the link phase.
5757 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
5758 rudimentary memory debugger which can be used on live servers with
5759 low impact -- it sets all allocated and freed memory bytes to 0xa5.
5760 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
5761 and free() for each object. This is far more expensive and should
5762 only be used for testing with tools such as Electric Fence and
5763 Purify. See main/alloc.c for more details. [Dean Gaudet]
5765 *) Configure uses a sh trap and didn't set its exitcode properly.
5766 [Dean Gaudet] PR#1159

5769 explicitly lists the ip:port pairs that are to be used for name-vhosts.
5770 From a given ip:port, regardless what the Host: header is, you can
5771 only reach the vhosts defined on that ip:port. The precedence of
5772 vhosts was reversed to match other precedences in the config --
5773 the earlier vhosts override the later vhosts. All vhost matching was
5774 moved into http_vhost.[ch]. [Dean Gaudet]
5776 *) ap_inline can be used to force inlining. GNUC __attribute__() can
5777 be used for whatever reason is appropriate (i.e. format() warnings
5778 for printf style functions). Both are enabled only with

5819 "RedirectMatch /advertiser/(.*) $1" is now permitted.

5827 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
5828 r->filename. Since those two are meant to be in sync with each other
5829 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
5831 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
5832 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]
5834 *) Inetd mode (which is buggy) uses timeouts without having setup the
5835 jmpbuffer. [Dean Gaudet] PR#1064
5837 *) Work around problem under Linux where a child will start looping
5838 reporting a select error over and over.
5839 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
5841 *) Fixed error in proxy_util.c when looping through multiple host IP
5842 addresses. [Lars Eilebrecht] PR#974
5844 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
5845 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
5846 bytes before writing, but it will never split a log entry across a
5847 buffer boundary. [Dean Gaudet]
5849 *) API: the short_score record has been split into two pieces, one which
5850 the parent writes on, and one which the child writes on. As part of
5851 this change the get_scoreboard_info() function was removed, and
5852 scoreboard_image was exported. This change fixes a race condition
5853 in file based scoreboard systems, and speeds up changes involving the
5854 scoreboard in earlier 1.3 development. [Dean Gaudet]
5856 *) API: New register_other_child() API (see http_main.h) which allows
5857 modules to register children with the parent for maintenance. It
5858 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
5860 *) API: New piped_log API (see http_log.h) which implements piped logs,
5861 and will use register_other_child to implement reliable piped logs
5862 when it is available. The reliable piped logs part can be disabled
5863 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
5864 logs is only available on Unix. [Dean Gaudet]
5866 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
5867 meets_conditions(). This allows conditional HTTP selection to be
5868 handled separately from the storing of the header fields, and provides
5869 the ability for CGIs to set their own ETags for conditional checking.
5870 [Ken Coar, Roy Fielding] PR#895
5872 *) Changes to mod_log_config to allow naming of format strings.
5873 Format nicknames are defined with "LogFormat fmt nickname", and can
5874 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
5877 *) New module, "mod_speling", which can help find files even when
5878 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
5880 *) API: New function child_terminate() triggers the child process to
5881 exit, while allowing the child finish what it needs to for the
5882 current request first.
5883 [Doug MacEachern, Alexei Kosut]
5885 *) Windows now defaults to using full status reports with mod_status.
5886 [Alexei Kosut] PR #1094
5888 *) *Really* disable all mod_rewrite operations if the engine is off.
5889 Some things (like RewriteMaps) were checked/performed even if they
5890 weren't supposed to be. [Ken Coar] PR #991
5892 *) Implement a new timer scheme which eliminates the need to call alarm() all
5893 the time. Instead a counter in the scoreboard for each child is used to
5894 show when the child has made forward progress. The parent samples this
5895 counter every scoreboard maintenance cycle, and issues SIGALRM if no
5896 progress has been made in the timeout period. This reduces the static
5897 request best-case syscall count to 22 from 29. This scheme is only
5898 used by systems with memory-based scoreboards. [Dean Gaudet]
5900 *) The proxy now properly handles CONNECT requests which are sent
5901 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
5903 *) A script called apachectl has been added to the support
5904 directory. This script allows you to do things such as
5905 "apachectl start" and "apachectl restart" from the command
5908 *) Modules and core routines are now put into libraries, which
5909 simplifies the link line tremendously (among other advantages).
5912 *) Some of the MD5 names defined in Apache have been renamed to have
5913 an `ap_' prefix to avoid conflicts with routines supplied by
5914 external libraries. [Ken Coar]
5916 *) Removal of mod_auth_msql.c from the distribution. There are many
5917 other options for databases today. Rather than offer one option,
5918 offer none at this time. mod_auth_msql and other SQL database
5919 authentication modules can be found at the Apache Module Registry.
5920 http://modules.apache.org/ It would be nice to offer a generic
5921 mod_auth_sql option in the near future.
5923 *) PORT: BeOS support added [Alexei Kosut]
5925 *) Configure no longer accepts the -make option, since it creates
5926 Makefile on the fly based on Makefile.tmpl and Configuration.
5928 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
5929 of forcibly killing off all its processes and exiting without
5930 cleaning up. [Alexei Kosut]
5932 *) API: A new field in the request_rec, r->mtime, has been added to
5933 avoid gratuitous parsing of date strings. It is intended to hold
5934 the last-modified date of the resource (if applicable). An
5935 update_mtime() routine has also been added to advance it if
5936 appropriate. [Roy Fielding, Ken Coar]
5938 *) SECURITY: If a htaccess file can not be read due to bad permissions,
5939 deny access to the directory with a HTTP_FORBIDDEN. The previous
5940 behavior was to ignore the htaccess file if it could not be read.
5941 This change may make some setups with unreadable htaccess files
5942 stop working. [Marc Slemko] PR#817
5944 *) Add aplog_error() providing a mechanism to define levels of
5945 verbosity to the server error logging. This addition also provides
5946 the ability to log errors using syslogd. Error logging is configurable
5947 on a per-server basis using the LogLevel directive. Conversion
5948 of log_*() in progress. [Randy Terbush]
5950 *) Further enhance aplog_error() to not log filename, line number, and
5951 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
5953 *) WIN32: Canonicalise filenames under Win32. Short filenames are
5954 converted to long ones. Backslashes are converted to forward
5955 slashes. Case is converted to lower. Parts of URLs that do not
5956 correspond to files are left completely alone. [Ben Laurie]
5958 *) PORT: 2 new OSs added to the list of ports:
5959 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
5960 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
5962 *) Add the server version (SERVER_VERSION macro) to the "server
5963 configured and running" entry in the error_log. Also build an
5964 object file at link-time that contains the current time
5965 (SERVER_BUILT global const char[]), and include that in the
5968 *) Set r->headers_out when sending responses from the proxy.
5969 This fixes things such as the logging of headers sent from
5970 the proxy. [Marc Slemko] PR#659
5972 *) support/httpd_monitor is no longer distributed because the
5973 scoreboard should not be file based if at all possible. Use
5974 mod_status to see current server snapshot.
5976 *) (set_file_slot): New function, allowing auth directives to be
5977 independent of the server root, so the server documents can be
5978 moved to a different directory or machine more easily.
5979 [David J. MacKenzie]
5981 *) If no TransferLog is given explicitly, decline
5982 to log. This supports coexistence with other logging modules,
5983 such as the custom one that UUNET uses. [David J. MacKenzie]
5985 *) Check for titles in server-parsed HTML files.
5986 Ignore leading newlines and returns in titles. The old behavior
5987 of replacing a newline after <title> with a space causes the
5988 title to be misaligned in the listing. [David J. MacKenzie]
5990 *) Change mod_cern_meta to be configurable on a per-directory basis.
5991 [David J. MacKenzie]
5993 *) Add 'Include' directive to allow inclusion of configuration
5994 files within configuration files. [Randy Terbush]
5996 *) Proxy errors on connect() are logged to the error_log (nothing
5997 new); now they include the IP address and port that failed
5998 (*that's* new). [Ken Coar, Marc Slemko] PR#352
6000 *) Various architectures now define USE_MMAP_FILES which causes
6001 the server to use mmap() for static files. There are two
6002 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
6003 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
6004 number of bytes written in one cycle from a single mmap()d object,
6005 default 32768). [Dean Gaudet]
6007 *) API: Added post_read_request API phase which is run right after reading
6008 the request from a client, or right after an internal redirect. It is
6009 useful for modules setting environment variables that depend only on
6010 the headers/contents of the request. It does not run during subrequests
6011 because subrequests inherit pretty much everything from the main
6012 request. [Dean Gaudet]
6014 *) Added mod_unique_id which is used to generate a unique identifier for
6015 each hit, available in the environment variable UNIQUE_ID.
6018 *) init_modules is now called after the error logs have been opened. This
6019 allows modules to emit information messages into the error logs.
6022 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
6023 information for case where proxy module is not available. [Marc Slemko]
6025 *) PORT: Apache has need for mutexes to serialize its children around
6026 accept. In prior versions either fcntl file locking or flock file
6027 locking were used. The method is chosen by the definition of
6028 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
6029 and FLOCK for flock(). New options have been added:
6030 - SYSVSEM to use System V style semaphores
6031 - PTHREAD to use POSIX threads (appears to work on Solaris only)
6032 - USLOCK to use IRIX uslock
6033 Based on timing various techniques, the following changes were made
6035 - Linux 2.x uses flock instead of fcntl
6036 - Solaris 2.x uses pthreads
6037 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
6038 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
6039 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
6040 Martijn Koster <m.koster@pobox.com>]
6042 *) PORT: The semantics of accept/select make it very desirable to use
6043 mutexes to serialize accept when multiple Listens are in use. But
6044 in the case where only a single socket is open it is sometimes
6045 redundant to serialize accept(). Not all unixes do a good job with
6046 potentially dozens of children blocked on accept() on the same
6047 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
6048 the server will avoid serialization when listening on only one socket,
6049 and use serialization when listening on multiple sockets.
6050 [Dean Gaudet] PR#467
6052 *) Configure changes: TestLib replaced by TestCompile, which has
6053 some additional capability (such as doing a sanity check of
6054 the compiler and flags selected); the version of Solaris is now
6055 available via the #define value of SOLARIS2; IRIX n32bit libs
6056 now supported and selectable by new Configuration Rule: IRIXN32;
6057 We no longer default to -O2 optimization. [Jim Jagielski]
6059 *) Updated Configure: Configuration now uses AddModule to specify
6060 module source or binary file location, relative to src directory.
6061 Modules can be dropped into modules/extra, or in their own
6062 directory, and modules can come with a Makefile or Configure can
6063 create one. Modules can add compiler or library information to
6064 generated Makefiles. [Paul Sutton]
6066 *) Source core re-organisation: distributed modules are now in
6067 modules/standard. All other source code is in main. OS-specific
6068 code is in os/{unix,emx,win32} directories. [Paul Sutton]
6070 *) mod_browser has been removed, since it's replaced by mod_setenvif.
6073 *) Fix another long-standing bug in sub_req_lookup_file where it would
6074 happily skip past access checks on subdirectories looked up with
6075 relative paths. (It's used by mod_dir, mod_negotiation,
6076 and mod_include.) [Dean Gaudet]
6078 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
6079 N is the number of <Directory> sections, and M is the number of
6080 components in the filename of an object.
6082 To achieve this optimization the following config changes were made:
6083 - Wildcards (* and ?, not the regex forms) in <Directory>s,
6084 <Files>s, and <Location>s now treat a slash as a special
6085 character. For example "/home/*/public_html" previously would
6086 match "/home/a/andrew/public_html", now it only matches things
6087 like "/home/bob/public_html". This mimics /bin/sh behaviour.
6088 - It's possible now to use [] wildcarding in <Directory>, <Files>
6090 - Regex <Directory>s are applied after all non-regex <Directory>s.
6094 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
6095 and corrupted paths. [Dean Gaudet]
6097 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
6098 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
6099 be accessed now via backreferences $1..$9 in RewriteConds test-against
6100 strings in addition to RewriteRules subst string. Second the grouped
6101 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
6102 via backreferences %1..%9 both in following RewriteCond test-against
6103 strings and RewriteRules subst string. This provides maximum flexibility
6104 through the use of backreferences.
6105 Additionally the rewriting engine was cleaned up by putting common
6106 code to the new expand_backrefs_inbuffer() function.
6107 [Ralf S. Engelschall]
6109 *) When merging the main server's <Directory> and <Location> sections into
6110 a vhost, put the main server's first and the vhost's second. Otherwise
6111 the vhost can't override the main server. [Dean Gaudet] PR#717
6113 *) The <Directory> code would merge and re-merge the same section after
6114 a match was found, possibly causing problems with some modules.
6117 *) ip-based vhosts are stored and queried using a hashing function, which
6118 has been shown to improve performance on servers with many ip-vhosts.
6119 Some other changes had to be made to accommodate this:
6120 - the * address for vhosts now behaves like _default_
6121 - the matching process now is:
6122 - match an ip-vhost directly via hash (possibly matches main
6124 - if that fails, just pretend it matched the main server
6125 - if so far only the main server has been matched, perform
6126 name-based lookups (ServerName, ServerAlias, ServerPath)
6127 *only on name-based vhosts*
6128 - if they fail, look for _default_ vhosts
6129 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
6131 *) dbmmanage overhaul:
6132 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
6133 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
6134 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
6135 - provide better seed for rand
6136 - prompt for password as per getpass(3) (turn off echo, read from
6138 - use "newstyle" crypt based on $Config{osname} ($^O)
6139 - will not add a user if already in database, use new `update' command
6141 - added `check' command to check a users' password
6142 - added `import' command to convert existing password text-files or
6143 dbm files exported with `view'
6144 - more descriptive usage, general cleanup, 'use strict' clean, etc.
6147 *) Added psocket() which is a pool form of socket(), various places within
6148 the proxy weren't properly blocking alarms while registering the cleanup
6149 for its sockets. bclose() now uses pclose() and pclosesocket(). There
6150 was a bug where the client socket was being close()d twice due a still
6151 registered cleanup. [Dean Gaudet]
6153 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
6156 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
6157 [Jason Venner <jason@idiom.com>] PR#667
6159 *) Enable ``=""'' for RewriteCond directives to match against
6160 the empty string. This is the preferred way instead of ``^$''.
6161 [Ralf S. Engelschall]
6163 *) Fixed an infinite loop in mod_imap for references above the server root
6164 [Dean Gaudet] PR#748
6166 *) mod_proxy now has a ReceiveBufferSize directive, similar to
6167 SendBufferSize, so that the TCP window can be set appropriately
6168 for LFNs. [Phillip A. Prindeville]
6170 *) mod_browser has been replaced by the more general mod_setenvif
6171 (courtesy of Paul Sutton). BrowserMatch* directives are still
6172 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
6173 UnSetEnvIfZero directives. [Ken Coar]
6175 *) "HostnameLookups double" forces double-reverse DNS to succeed in
6176 order for remote_host to be set (for logging, or for the env var
6177 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
6180 *) mod_access overhaul:
6181 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
6182 and cidr syntax (i.e. 10.1.0.0/16). PR#762
6183 - Critical path was sped up by pre-computing a few things at config time.
6184 - The undocumented syntax "allow user-agents" was removed,
6185 the replacement is "allow from env=foobar" combined with mod_browser.
6186 - When used with hostnames it now forces a double-reverse lookup
6187 no matter what the directory settings are. This double-reverse
6188 doesn't affect any of the other routines that use the remote
6189 hostname. In particular it's still passed to CGIs and the log
6190 without the double-reverse check. Related PR#860.
6193 *) When a large bwrite() occurs (larger than the internal buffer size),
6194 while there is already something in the buffer, apache will combine
6195 the large write and the buffer into a single writev(). (This is
6196 in anticipation of using mmap() for reading files.)
6199 *) In obscure cases where a partial socket write occurred while chunking,
6200 Apache would omit the chunk header/footer on the next block. Cleaned
6201 up other bugs/inconsistencies in error conditions in buff.c. Fixed
6202 a bug where a long pause in DNS lookups could cause the last packet
6203 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
6205 *) API: Added child_exit function to module structure. This is called
6206 once per "heavy-weight process" just before a server child exit()'s
6207 e.g. when max_requests_per_child is reached, etc.
6208 [Doug MacEachern, Dean Gaudet]
6210 *) mod_include cleanup showed that handle_else was being used to handle
6211 endif. It didn't cause problems, but it was cleaned up too.
6214 *) mod_cern_meta would attempt to find meta files for the directory itself
6215 in some cases, but not in others. It now avoids it in all cases.
6218 *) mod_mime_magic would core dump if there was a decompression error.
6219 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
6221 *) PORT: some variants of DGUX require -lsocket -lnsl

6224 *) mod_autoindex now allows sorting of FancyIndexed directory listings
6225 by the various fields (name, size, et cetera), either in ascending
6226 or descending order. Just click on the column header. [Ken Coar]
6228 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
6229 CPUs like the Alpha. Apache still stores ints in pointers, but that's
6230 the relatively safe direction. [Dean Gaudet] PR#344
6232 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
6233 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
6235 *) child_main avoids an unneeded call to select() when there is only one
6236 listening socket. [Dean Gaudet]
6238 *) In the event that the server is starved for idle servers it will
6239 spawn 1, then 2, then 4, ..., then 32 servers each second,
6240 doubling each second. It'll also give a warning in the errorlog
6241 since the most common reason for this is a poor StartServers
6242 setting. The define MAX_SPAWN_RATE can be used to raise/lower
6243 the maximum. [Dean Gaudet]
6245 *) Apache now provides an effectively unbuffered connection for
6246 CGI scripts. This means that data will be sent to the client
6247 as soon as the CGI pauses or stops output; previously, Apache would
6248 buffer the output up to a fixed buffer size before sending, which
6249 could result in the user viewing an empty page until the CGI finished
6250 or output a complete buffer. It is no longer necessary to use an
6251 "nph-" CGI to get unbuffered output. Given that most CGIs are written
6252 in a language that by default does buffering (e.g. perl) this
6253 shouldn't have a detrimental effect on performance.
6255 "nph-" CGIs, which formerly provided a direct socket to the client
6256 without any server post-processing, were not fully compatible with
6257 HTTP/1.1 or SSL support. As such they would have had to implement
6258 the transport details, such as encryption or chunking, in order
6259 to work properly in certain situations. Now, the only difference
6260 between nph and non-nph scripts is "non-parsed headers".

6267 Changes with Apache 1.3a1
6269 *) Added another Configure helper script: TestLib. It determines
6270 if a specified library exists. [Jim Jagielski]
6272 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
6273 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
6276 *) PORT: Some architectures use size_t for various lengths in network
6277 functions such as accept(), and getsockname(). The definition
6278 NET_SIZE_T is used to control this. [Dean Gaudet]
6280 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
6281 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
6282 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
6284 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
6285 [Igor N Kovalenko <infoh@mail.wplus.net>]
6287 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
6288 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
6289 "downgrade-1.0" which causes Apache to pretend it received a 1.0.

6330 This update also removes the copyright of Ralf S. Engelschall,
6331 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
6332 exclusively copyrighted by the Apache Group now. This happened because
6333 the author now has gifted mod_rewrite exclusively to the Apache Group and
6334 no longer maintains an external version.
6335 [Ralf S. Engelschall]
6337 *) API: Added child_init function to module structure. This is called
6338 once per "heavy-weight process" before any requests are handled.
6339 See http_config.h for more details. [Dean Gaudet]
6341 *) Anonymous_LogEmail was logging on each subrequest.
6342 [Dean Gaudet] PR#421, 868
6344 *) API: Added is_initial_req() which tests if the request being
6345 processed is the initial request, or a subrequest.
6348 *) Extended SSI (mod_include) now handles additional relops for
6349 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
6351 *) Configure fixed to correctly propagate user-selected options and
6352 settings (such as CC and OPTIM) to Makefiles other than
6353 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
6355 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
6356 directory indices to start with the contents of the HeaderName file
6357 if there is one. If there isn't one, the behaviour is unchanged.
6358 [Ken Coar, Roy Fielding, Andrey A. Chernov]
6360 *) WIN32: Modules can now be dynamically loaded DLLs using the
6361 LoadModule/LoadFile directives. Note that module DLLs must be
6362 compiled with the multithreaded DLL version of the runtime library.
6363 [Alexei Kosut and Ben Laurie]
6365 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
6366 This allows the admin to completely remove automatic indexing
6367 from the server, while still supporting the basic functions of
6368 trailing-slash redirects and DirectoryIndex files. Note that if
6369 you're carrying over an old Configuration file and you use directory
6370 indexing then you'll want to add:
6372 Module autoindex_module mod_autoindex.o
6374 before mod_dir in your Configuration. [Dean Gaudet]
6376 *) popendir/pclosedir created to properly protect directory scanning.
6377 [Dean Gaudet] PR#525
6379 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
6380 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
6381 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
6384 *) The AccessFileName directive can now take more than one filename.
6385 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
6387 *) The new mod_mime_magic can be used to "magically" determine the type
6388 of a file if the extension is unknown. Based on the unix file(1)
6389 command. [Ian Kluft <ikluft@cisco.com>]
6391 *) We now determine and display the time spent processing a
6392 request if desired. [Jim Jagielski]
6394 *) mod_status: PID field of "dead" child slots no longer displays
6395 main httpd process's PID. [Jim Jagielski]
6397 *) Makefile.nt added - to build all the bits from the command line:
6398 nmake -f Makefile.nt
6399 Doesn't yet work properly. [Ben Laurie]
6401 *) Default text of 404 error is now "Not Found" rather than the
6402 potentially misleading "File Not Found". [Ken Coar]
6404 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
6405 for the net if we require people that actually need this data to
6406 enable it. [Linus Torvalds]
6408 *) directory_walk() is an expensive function, keep a little more state to
6409 avoid needless string counting. Add two new functions make_dirstr_parent
6410 and make_dirstr_prefix which replace all existing uses of make_dirstr.
6411 The new functions are a little less general than make_dirstr, but
6412 work more efficiently (less memory, less string counting).
6415 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
6416 to LDFLAGS) to avoid complications with lex rules in make files.
6417 [Dean Gaudet] PR#372
6419 *) run_method optimized to avoid needless scanning over NULLs in the
6420 module list. [Dean Gaudet]
6422 *) Revamp of (unix) scoreboard management code such that it avoids
6423 unnecessary traversals of the scoreboard on each hit. This is
6424 particularly important for high volume sites with a large
6425 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
6426 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
6427 httpd.h. [Dean Gaudet]
6429 *) In configurations using multiple Listen statements it was possible for
6430 busy sockets to starve other sockets of service. [Dean Gaudet]
6432 *) Added hook so standalone_main can be replaced at compile time
6433 (define STANDALONE_MAIN)
6436 *) Lowest-level read/write functions in buff.c will be replaced with
6437 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
6438 compile time. The default sfio discipline will behave as apache
6439 would without sfio compiled in.
6442 *) Enhance UserDir directive (mod_userdir) to accept a list of
6443 usernames for the 'disable' keyword, and add 'enable user...' to
6444 selectively *en*able userdirs if they're globally disabled.
6447 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
6448 will work with Netscape dbm files. (dbmmanage will probably not
6449 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
6451 *) Add a ListenBacklog directive to control the backlog parameter
6452 passed to listen(). Also change the default to 511 from 512.
6455 *) API: A new handler response DONE which informs apache that the
6456 request has been handled and it can finish off quickly, similar to
6457 how it handles errors. [Rob Hartill]
6459 *) Turn off chunked encoding after sending terminating chunk/footer
6460 so that we can't do it twice by accident. [Roy Fielding]
6462 *) mod_expire also issues Cache-Control: max-age headers.
6465 *) API: Added kill_only_once option for free_proc_chain so that it won't
6466 aggressively try to kill off specific children. For fastcgi.
6467 [Stanley Gambarin <gambarin@OpenMarket.com>]
6469 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
6471 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
6472 When used together, these cause mod_dir to emit HEIGHT and WIDTH
6473 attributes in the FancyIndexing IMG tags. [Ken Coar]
6475 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
6477 *) PORT: Added Windows NT support
6478 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
6480 Changes with Apache 1.2.6
6482 *) mod_include when using XBitHack Full would send ETags in addition to
6483 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
6484 [Dean Gaudet] PR#1133
6486 *) SECURITY: When a client connects to a particular port/addr, and
6487 gives a Host: header ensure that the virtual host requested can
6488 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
6490 *) Support virtual hosts with wildcard port and/or multiple ports
6491 properly. [Ed Korthof <ed@organic.com>]
6493 *) Fixed some case-sensitivity issues according to RFC2068.
6496 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
6497 and mod_include.c. [Dean Gaudet]
6499 *) Variable 'cwd' was being used pointlessly before being set.
6502 *) SIGURG doesn't exist on all platforms.
6503 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
6505 *) When an error occurs during a POST, or other operation with a
6506 request body, the body has to be read from the net before allowing
6507 a keepalive session to continue. [Roy Fielding] PR#1399
6509 *) When an error occurs in fcntl() locking suggest the user look up
6510 the docs for LockFile. [Dean Gaudet]
6512 *) table_set() and table_unset() did not deal correctly with
6513 multiple occurrences of the same key. [Stephen Scheck
6514 <sscheck@infonex.net>, Ben Laurie] PR#1604
6516 *) send_fd_length() did not calculate total_bytes_sent properly in error
6517 cases. [Ben Reser <breser@regnow.com>] PR#1366
6519 *) r->connection->user was allocated in the wrong pool causing corruption
6520 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
6522 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
6523 Also removed the auto-generated link to www.apache.org that was the
6524 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
6526 *) Multiple "close" tokens may have been set in the "Connection"
6527 header, not an error, but a waste.
6528 [Ronald.Tschalaer@psi.ch] PR#1683
6530 *) "basic" and "digest" auth tokens should be tested case-insensitive.
6531 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
6533 *) It appears the "257th byte" bug (see
6534 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
6535 at the 256th byte as well. Fixed. [Dean Gaudet]
6537 *) mod_rewrite would not handle %3f properly in some situations.
6540 *) Apache could generate improperly chunked HTTP/1.1 responses when
6541 the bputc() or rputc() functions were used by modules (such as
6542 mod_include). [Dean Gaudet]
6544 *) #ifdef wrap a few #defines in httpd.h to make life easier on
6545 some ports. [Ralf Engelschall]
6547 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
6549 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
6551 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
6553 Changes with Apache 1.2.5
6555 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
6556 only an issue on systems without a MAXDNAME define or where
6557 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
6559 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
6562 *) Fix core dump in the ftp proxy when reading incorrectly formatted
6563 directory listings. [Marc Slemko]
6565 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
6568 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
6569 is used to read various types of files such as htaccess and
6570 htpasswd files. [Marc Slemko]
6572 *) SECURITY: Ensure that the buffer returned by ht_time is always
6573 properly null terminated. [Marc Slemko]
6575 *) SECURITY: General mod_include cleanup, including fixing several
6576 possible buffer overflows and a possible infinite loop. This cleanup
6577 was done against 1.3 code and then backported to 1.2, the result
6578 is a large difference (due to indentation cleanup in 1.3 code).
6579 Users interested in seeing a smaller set of relevant differences
6580 should consider comparing against src/modules/standard/mod_include.c
6581 from the 1.3b3 release. Non-indentation changes to mod_include
6582 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
6584 *) SECURITY: Numerous changes to mod_imap in a general cleanup
6585 including fixing a possible buffer overflow. This cleanup also
6586 was done with 1.3 code as a basis, see the the previous note
6587 about mod_include. [Dean Gaudet]
6589 *) SECURITY: If a htaccess file can not be read due to bad
6590 permissions, deny access to the directory with a HTTP_FORBIDDEN.
6591 The previous behavior was to ignore the htaccess file if it could not
6592 be read. This change may make some setups with unreadable
6593 htaccess files stop working. PR#817 [Marc Slemko]
6595 *) SECURITY: no2slash() was O(n^2) in the length of the input.
6596 Make it O(n). This inefficiency could be used to mount a denial
6597 of service attack against the Apache server. Thanks to
6598 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting
6601 *) mod_include used uninitialized data for some uses of && and ||.
6602 [Brian Slesinsky <bslesins@wired.com>] PR#1139
6604 *) mod_imap should decline all non-GET methods.
6605 [Jay Bloodworth <jay@pathways.sde.state.sc.us>]
6607 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
6609 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
6610 r->filename. Since those two are meant to be in sync with each other
6611 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
6613 *) mod_include did not properly handle all possible redirects from sub-
6614 requests. [Ken Coar]
6616 *) Inetd mode (which is buggy) uses timeouts without having setup the
6617 jmpbuffer. [Dean Gaudet] PR#1064
6619 *) Work around problem under Linux where a child will start looping
6620 reporting a select error over and over.
6621 [Rick Franchuk <rickf@transpect.net>] PR#1107
6623 Changes with Apache 1.2.4
6625 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
6626 always making requests with the full-URI instead of just the URI path.
6627 [Marc Slemko, Roy Fielding]
6629 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
6630 on this platform. [Marc Slemko]
6632 Changes with Apache 1.2.3
6634 *) The request to a remote proxy was mangled if it was generated as the
6635 result of a ProxyPass directive. URL schemes other than http:// were not
6636 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
6637 PR#812 [Lars Eilebrecht]
6639 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
6640 information for case where proxy module is not available. [Marc Slemko]
6642 *) Force proxy to always respond as HTTP/1.0, which it was failing to
6643 do for errors and cached responses. [Roy Fielding]
6645 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
6647 Changes with Apache 1.2.2 [not released]
6649 *) Fixed another long-standing bug in sub_req_lookup_file where it would
6650 happily skip past access checks on subdirectories looked up with relative
6651 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
6654 *) Add lockfile name to error message printed out when
6655 USE_FLOCK_SERIALIZED_ACCEPT is defined.
6658 *) Enhanced the chunking and error handling inside the buffer functions.
6659 [Dean Gaudet, Roy Fielding]
6661 *) When merging the main server's <Directory> and <Location> sections into
6662 a vhost, put the main server's first and the vhost's second. Otherwise
6663 the vhost can't override the main server. [Dean Gaudet] PR#717
6665 *) The <Directory> code would merge and re-merge the same section after
6666 a match was found, possibly causing problems with some modules.
6669 *) Fixed an infinite loop in mod_imap for references above the server root.
6670 [Dean Gaudet] PR#748
6672 *) mod_include cleanup showed that handle_else was being used to handle
6673 endif. It didn't cause problems, but it was cleaned up too.
6676 *) Last official synchronization of mod_rewrite with author version (because
6677 mod_rewrite is now directly developed by the author at the Apache Group):
6678 o added diff between mod_rewrite 3.0.6+ and 3.0.9
6679 minus WIN32/NT stuff, but plus copyright removement.
6681 - workaround for detecting infinite rewriting loops
6682 - fixed setting of env vars when "-" is used as subst string
6683 - fixed forced response code on redirects (PR#777)
6684 - fixed cases where r->args is ""
6685 - kludge to disable locking on pipes under braindead SunOS
6686 - fix for rewritelog in cases where remote hostname is unknown
6687 - fixed totally damaged request_rec walk-back loop
6688 o remove static from local data and add static to global ones.
6689 o replaced ugly proxy finding stuff by simple
6690 find_linked_module("mod_proxy") call.
6691 o added missing negation char on rewritelog()
6692 o fixed a few comment typos
6693 [Ralf S. Engelschall]
6695 *) Anonymous_LogEmail was logging on each subrequest.
6696 [Dean Gaudet] PR#421, PR#868
6698 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
6699 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
6700 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
6701 Additionally mod_browser now triggers during translate_name to workaround
6702 a deficiency in the header_parse phase.
6703 [Dean Gaudet] PR#875

6712 *) The proxy didn't treat the "Host:" keyword of the host header as case-
6713 insensitive. The proxy would corrupt the first line of a response from
6714 an HTTP/0.9 server. [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#813,814
6716 *) mod_include would log some bogus values occasionally.
6717 [Skip Montanaro <skip@calendar.com>, Marc Slemko] PR#797
6719 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
6720 under Solaris 2.x (up through 2.5.1). It has been fixed.
6721 [Dean Gaudet] PR#832
6723 *) API: In HTTP/1.1, whether or not a request message contains a body
6724 is independent of the request method and based solely on the presence
6725 of a Content-Length or Transfer-Encoding. Therefore, our default
6726 handlers need to be prepared to read a body even if they don't know
6727 what to do with it; otherwise, the body would be mistaken for the
6728 next request on a persistent connection. discard_request_body()
6729 has been added to take care of that. [Roy Fielding] PR#378
6731 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
6732 release version number, such that it always increases along the
6733 same lines as our source code branching. [Roy Fielding]
6735 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
6737 Changes with Apache 1.2.1
6739 *) SECURITY: Don't serve file system objects unless they are plain files,
6740 symlinks, or directories. This prevents local users from using pipes
6741 or named sockets to invoke programs for an extremely crude form of

6745 could contain "../" allowing a local user to "publish" any file on
6746 the system. No slashes are allowed now. [Dean Gaudet]
6748 *) SECURITY: It was possible to violate the symlink Options using mod_dir
6749 (headers, readmes, titles), mod_negotiation (type maps), or
6750 mod_cern_meta (meta files). [Dean Gaudet]
6752 *) SECURITY: Apache will refuse to run as "User root" unless
6753 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
6755 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
6756 if it contained a .htaccess disallowing symlinks. This is contrary
6757 to the rule that symlink permissions are tested with the symlink
6758 options of the parent directory. [Dean Gaudet] PR#353
6760 *) CONFIG: The LockFile directive can be used to place the serializing
6761 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
6762 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
6765 *) Request processing now retains state of whether or not the request
6766 body has been read, so that internal redirects and subrequests will
6767 not try to read it twice (and block). [Roy Fielding]

6779 handle high numbered descriptors (examples include bind, and
6780 solaris libc). On all systems apache attempts to keep all permanent
6781 descriptors above 15 (called the low slack line). Solaris users
6782 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
6783 which keeps all non-FILE * descriptors above 255. On all systems
6784 this should make supporting large numbers of vhosts with many open
6785 log files more feasible. If this causes trouble please report it,
6786 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
6787 [Dean Gaudet] various PRs
6789 *) Related to the last entry, network sockets are now opened before
6790 log files are opened. The only known case where this can cause
6791 problems is under Solaris with many virtualhosts and many Listen

6793 work around this problem. [Dean Gaudet]

6873 *) The OS/2 handling of process group was broken by a porting patch for
6874 MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]
6876 *) Inherit virtual server port from main server if none (or "*") is
6877 given for VirtualHost. [Dean Gaudet] PR#576
6879 *) If the lookup for a DirectoryIndex name with content negotiation
6880 has found matching variants, but none are acceptable, return the
6881 negotiation result if there are no more DirectoryIndex names to lookup.
6882 [Petr Lampa and Roy Fielding]
6884 *) If a soft_timeout occurs after keepalive is set, then the main child
6885 loop would try to read another request even though the connection
6886 has been aborted. [Roy Fielding]
6888 *) Configure changes: Allow for whitespace at the start of a
6889 Module declaration. Also, be more understanding about the
6890 CC=/OPTIM= format in Configuration. Finally, fix compiler
6891 flags if using HP-UX's cc compiler. [Jim Jagielski]
6893 *) Subrequests and internal redirects now inherit the_request from the
6894 original request-line. [Roy Fielding]
6896 *) Test for error conditions before creating output header fields, since
6897 we don't want the error message to include those fields. Likewise,
6898 reset the content_language(s) and content_encoding of the response
6899 before generating or redirecting to an error message, since the new
6900 message will have its own Content-* definitions. [Dean Gaudet]
6902 *) Restored the semantics of headers_out (headers sent only with 200..299
6903 and 304 responses) and err_headers_out (headers sent with all responses).
6904 Avoid the overhead of copying tables if err_headers_out is empty
6905 (the usual case). [Roy Fielding]
6907 *) Fixed a couple places where a check for the default Content-Type was
6908 not properly checking both the value configured by the DefaultType
6909 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
6910 of DEFAULT_TYPE to match the documented default (text/plain).
6911 [Dean Gaudet] PR#506
6913 *) Escape the HTML-sensitive characters in the Request-URI that is
6914 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
6916 *) Properly initialize the flock structures used by the mutex locking
6917 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
6920 *) The method for determining PATH_INFO has been restored to the pre-1.2b
6921 (and NCSA httpd) definition wherein it was the extra path info beyond
6922 the CGI script filename. The environment variable FILEPATH_INFO has
6923 been removed, and instead we supply the original REQUEST_URI to any
6924 script that wants to be Apache-specific and needs the real URI path.
6925 This solves a problem with existing scripts that use extra path info
6926 in the ScriptAlias directive to pass options to the CGI script.
6929 *) The _default_ change in 1.2b10 will change the behaviour on configs
6930 that use multiple Listen statements for listening on multiple ports.
6931 But that change is necessary to make _default_ consistent with other
6932 forms of <VirtualHost>. It requires such configs to be modified
6933 to use <VirtualHost _default_:*>. The documentation has been
6934 updated. [Dean Gaudet] PR#530
6936 *) If an ErrorDocument CGI script is used to respond to an error
6937 generated by another CGI script which has already read the message
6938 body of the request, the server would block trying to read the
6939 message body again. [Rob Hartill]
6941 *) signal() replacement conflicted with a define on QNX (and potentially
6942 other platforms). Fixed. [Ben Laurie] PR#512
6944 Changes with Apache 1.2b10
6946 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
6947 to be configured via -D in Configuration. [Dean Gaudet] PR#449
6949 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
6951 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]
6953 *) In mod_proxy.c, check return values for proxy_host2addr() when reading
6954 config, in case the hostent struct returned is trash.
6955 [Chuck Murcko] PR #491
6957 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
6958 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
6960 Changes with Apache 1.2b9 [never announced]
6962 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
6963 changes and in anticipation of 1.2 final release. [Roy Fielding]
6965 *) Fix problem with scripts not receiving a SIGPIPE when client drops
6966 the connection (e.g., when user presses Stop). Apache will now stop
6967 trying to send a message body immediately after an error from write.
6968 [Roy Fielding and Nathan Kurz] PR#335
6970 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
6971 than mod_alias, and mod_alias has higher priority than mod_proxy;
6972 rearranged other modules to enhance understanding of their purpose
6973 and relative order (and maybe even reduce some overhead).
6974 [Roy Fielding and Sameer Parekh]
6976 *) Fix graceful restart. Eliminate many signal-related race
6977 conditions in both forms of restart, and in SIGTERM. See
6978 htdocs/manual/stopping.html for details on stopping and
6979 restarting the parent. [Dean Gaudet]
6981 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
6982 memory allocator to avoid a behaviour that required extra blocks to
6983 be allocated. [Dean Gaudet]
6985 *) Allow suexec to access files relative to current directory but not
6986 above. (Excluding leading / or any .. directory.) [Ken Coar]
6989 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
6990 PR#367, 368, 354, 453
6992 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
6993 while obtaining the /~user and save the username in a separate data
6994 area so that it won't be overwritten by the call to getgrgid(), and
6995 fix some misuse of the pool string allocation functions. Also fixes
6996 a general problem with parsing URL query info into args for CGI scripts.
6997 [Roy Fielding] PR#339, 367, 354, 453
6999 *) Fix IRIX warning about bzero undefined. [Marc Slemko]

7004 AuthDBAuthoritative. [Marc Slemko] PR#420
7006 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
7008 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
7009 object that can't be PUT, or FOOBAR for some method FOOBAR that
7010 apache doesn't know about at all). Log 404s that occur in mod_include.
7011 [Paul Sutton, John Van Essen]
7013 *) If a soft timeout (or lingerout) occurs while trying to flush a
7014 buffer or write inside buff.c or fread'ing from a CGI's output,
7015 then the timeout would be ignored. [Roy Fielding] PR#373
7017 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
7018 parsing of headers. If the terminating empty-line CRLF occurs starting
7019 at the 256th or 257th byte of output, then Navigator will think a normal
7020 image is invalid. We are guessing that this is because their initial
7021 read of a new request uses a 256 byte buffer. We check the bytes written
7022 so far and, if we are about to tickle the bug, we instead insert a
7023 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
7025 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
7026 of an external redirection. [Roy Fielding and Paul Sutton]
7028 *) Configure would create a broken Makefile if the configuration file
7029 contained a commented-out Rule. [Roy Fielding]
7031 *) Promote per_dir_config and subprocess_env from the subrequest to the
7032 main request in mod_negotiation. In particular this fixes a bug
7033 where <Files> sections wouldn't properly apply to negotiated content.
7036 *) Fix a potential deadlock in mod_cgi script_err handling.
7037 [Ralf S. Engelschall]
7039 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
7042 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
7043 .htaccess files because the RewriteBase was not replaced correctly.
7044 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
7045 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
7047 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
7048 1.x the settings are those of pre-1.2b8. For 2.x we include
7049 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
7050 HAVE_SYS_RESOURCE_H (enable the RLimit commands).

7058 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
7060 *) Add UnixWare compile/install instructions. [Chuck Murcko]
7062 *) Add mod_example (illustration of API techniques). [Ken Coar]
7064 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
7066 *) Improve handling of directories when filenames have spaces in them.
7069 *) For hosts with multiple IP addresses, try all additional addresses if
7070 necessary to get a connect. Fail only if hostent address list is
7071 exhausted. [Chuck Murcko]
7073 *) More signed/unsigned port fixes. [Dean Gaudet]
7075 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
7078 Changes with Apache 1.2b8
7080 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
7081 to it. [Marc Slemko]
7083 *) The addition of <Location> and <File> directives made the
7084 sub_req_lookup_simple() function bogus, so we now handle
7085 the special cases directly. [Dean Gaudet]
7087 *) We now try to log where the server is dumping core when a fatal
7088 signal is received. [Ken Coar]
7090 *) Improved lingering_close by adding a special timeout, removing the
7091 spurious log messages, removing the nonblocking settings (they
7092 are not needed with the better timeout), and adding commentary
7093 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
7094 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
7096 *) Send error messages about setsockopt failures to the server error
7097 log instead of stderr. [Roy Fielding]
7099 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
7101 *) Stopgap solution for CGI 3-second delay with server-side includes: if
7102 processing a subrequest, allocate memory from r->main->pool instead
7103 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
7104 in the middle of an SSI request. [Dean Gaudet] PR #122
7106 *) Fixed status of response when POST is received for a nonexistent URL
7107 (was sending 405, now 404) and when any method is sent with a
7108 full-URI that doesn't match the server and the server is not acting
7109 as a proxy (was sending 501, now 403). [Roy Fielding]
7111 *) Host port changed to unsigned short. [Ken Coar] PR #276
7113 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
7115 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
7117 *) Report extra info from errno with many errors that cause httpd to exit.
7118 spawn_child, popenf, and pclosef now have valid errno returns in the
7119 event of an error. Correct problems where errno was stomped on
7120 before being reported. [Dean Gaudet]
7122 *) In the proxy, if the cache filesystem was full, garbage_coll() was
7123 never called, and thus the filesystem would remain full indefinitely.
7124 We now also remove incomplete cache files left if the origin server
7125 didn't send a Content-Length header and either the client has aborted
7126 transfer or bwrite() to client has failed. [Petr Lampa]
7128 *) Fixed the handling of module and script-added header fields.
7129 Improved the interface for sending header fields and reduced
7130 the duplication of code between sending okay responses and errors.
7131 We now always send both headers_out and err_headers_out, and
7132 ensure that the server-reserved fields are not being overridden,
7133 while not overriding those that are not reserved. [Roy Fielding]
7135 *) Moved transparent content negotiation fields to err_headers_out
7136 to reflect above changes. [Petr Lampa]
7138 *) Fixed the determination of whether or not we should make the
7139 connection persistent for all of the cases where some other part
7140 of the server has already indicated that we should not. Also
7141 improved the ordering of the test so that chunked encoding will
7142 be set whenever it is desired instead of only when KeepAlive
7143 is enabled. Added persistent connection capability for most error
7144 responses (those that do not indicate a bad input stream) when
7145 accessed by an HTTP/1.1 client. [Roy Fielding]
7147 *) Added missing timeouts for sending header fields, error responses,
7148 and the last chunk of chunked encoding, each of which could have
7149 resulted in a process being stuck in write forever. Using soft_timeout
7150 requires that the sender check for an aborted connection rather than
7151 continuing after an EINTR. Timeouts that used to be initiated before
7152 send_http_header (and never killed) are now initiated only within or
7153 around the routines that actually do the sending, and not allowed to
7154 propagate above the caller. [Roy Fielding]
7156 *) mod_auth_anon required an @ or a . in the email address, not both.
7159 *) per_dir_defaults weren't set correctly until directory_walk for
7160 name-based vhosts. This fixes an obscure bug with the wrong config
7161 info being used for vhosts that share the same ip as the server.
7164 *) Improved generation of modules/Makefile to be more generic for
7165 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
7167 *) Generate makefile dependency for Configuration based on the actual
7168 name given when running the Configure process. [Dean Gaudet]
7170 *) Fixed problem with vhost error log not being set prior to
7171 initializing virtual hosts. [Dean Gaudet]
7173 *) Fixed infinite loop when a trailing slash is included after a type map
7174 file URL (extra path info). [Petr Lampa]
7176 *) Fixed server status updating of per-connection counters. [Roy Fielding]
7178 *) Add documentation for DNS issues (reliability and security), and try
7179 to explain the virtual host matching process. [Dean Gaudet]
7181 *) Try to continue gracefully by disabling the vhost if a DNS lookup
7182 fails while parsing the configuration file. [Dean Gaudet]
7184 *) Improved calls to setsockopt. [Roy Fielding]
7186 *) Negotiation changes: Don't output empty content-type in variant list;
7187 Output charset in variant list; Return sooner from handle_multi() if
7188 no variants found; Add handling of '*' wildcard in Accept-Charset.
7189 [Petr Lampa and Paul Sutton]
7191 *) Fixed overlaying of request/sub-request notes and headers in
7192 mod_negotiation. [Dean Gaudet]
7194 *) If two variants' charset quality are equal and one is the default
7195 charset (iso-8859-1), then prefer the variant that was specifically
7196 listed in Accept-Charset instead of the default. [Petr Lampa]
7198 *) Memory allocation problem in push_array() -- it would corrupt memory
7199 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
7201 *) invoke_handler() doesn't handle mime arguments in content-type
7204 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
7207 *) Fixed problem with ErrorDocument not working for virtual hosts
7208 due to one of the performance changes in 1.2b7. [Dean Gaudet]
7210 *) Log an error message if we get a request header that is too long,
7211 since it may indicate a buffer overflow attack. [Marc Slemko]
7213 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
7214 not reject URLs without a double-slash, as per RFC2068 section 3.2.
7215 [Ken Coar] PR #146, #187
7217 *) Added table entry placeholder for new header_parser callback
7218 in all of the distributed modules. [Ken Coar] PR #191
7220 *) Allow for cgi files without the .EXE extension on them under OS/2.
7221 [Garey Smiley] PR #59
7223 *) Fixed error message when resource is not found and URL contains
7224 path info. [Petr Lampa and Dean Gaudet] PR #40
7226 *) Fixed user and server confusion over what should be a virtual host
7227 and what is the main server, resulting in access to something
7228 other than the name defined in the virtualhost directive (but
7229 with the same IP address) failing. [Dean Gaudet]
7231 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
7232 AIX; improves the redirection stuff to enable the users to generally
7233 redirect to http, https, gopher and ftp; added TIME variable for
7234 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
7235 special patterns >STRING, <STRING and =STRING to RewriteCond, which
7236 can be used in conjunction with %{TIME} or other variables to create
7237 time-dependent rewriting rules. [Ralf S. Engelschall]
7239 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
7240 Module authors may need to adjust their code for proper cleanup to take
7241 place (that is, call note_cleanups_for_fd()). This change fixes problems
7242 with file descriptors being erroneously closed when the proxy module was
7243 in use. [Ben Laurie]
7245 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
7246 initgroups() to hose the group information needed for later
7247 comparisons. [Randy Terbush]
7249 *) Remove unnecessary call to va_end() in create_argv() which
7250 caused a SEGV on some systems.
7252 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
7255 *) Clear memory allocated for listeners. [Randy Terbush]
7257 *) Improved handling of IP address as a virtualhost address and
7258 introduced "_default_" as a synonym for the default vhost config.

7268 - replace protocol response numbers with symbols
7269 - save variant-list into main request notes
7270 - free allocated memory from subrequests

7273 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
7274 "HTTP/#.# ###*" to be more lenient about what we accept.
7277 *) more proxy FTP bug fixes:
7278 - Changed send_dir() to remove user/passwd from displayed URL.
7279 - Changed login error messages to be more descriptive.
7280 - remove setting of SO_DEBUG socket option
7281 - Make ftp_getrc() more lenient about multiline responses,
7282 specifically, 230 responses which don't have continuation 230-
7283 on each line). These seem to be all NT FTP servers, and while
7284 perhaps questionable, they appear to be legal by RFC 959.
7285 - Add missing kill_timeout() after transfer to user completes.
7288 *) Fixed problem where a busy server could hang when restarting
7289 after being sent a SIGHUP due to child processes not exiting.
7292 *) Modify mod_include escaping so a '\' only signifies an escaped
7293 character if the next character is one that needs
7294 escaping. [Ben Laurie]
7296 *) Eliminated possible infinite loop in mod_imap when relative URLs are
7297 used with a 'base' directive that does not have a '/' in it.
7298 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
7300 *) Reduced the default timeout from 1200 seconds to 300, and the
7301 one in the sample configfile from 400 to 300. [Marc Slemko]
7303 *) Stop vbprintf from crashing if given a NULL string pointer;
7304 print (null) instead. [Ken Coar]
7306 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
7307 [Marc Slemko and Roy Fielding]
7309 *) Fixed problem with mod_cgi-generated internal redirects trying to
7310 read the request message-body twice. [Archie Cobbs and Roy Fielding]
7312 *) Reduced timeout on lingering close, removed possibility of a blocked
7313 read causing the child to hang, and stopped logging of errors if
7314 the socket is not connected (reset by client). [Roy Fielding]
7316 *) Rearranged main child loop to remove duplication of code in
7317 select/accept and keep-alive requests, fixed several bugs regarding
7318 checking scoreboard_image for exit indication and failure to
7319 account for all success conditions and trap all error conditions,
7320 prevented multiple flushes before closing the socket; close the entire
7321 socket buffer instead of just one descriptor, prevent logging of
7322 EPROTO and ECONNABORTED on platforms where supported, and generally
7323 improved readability. [Roy Fielding]
7325 *) Extensive performance improvements. Cleaned up inefficient use of
7326 auto initializers, multiple is_matchexp calls on a static string,
7327 and excessive merging of response_code_strings. [Dean Gaudet]
7329 *) Added double-buffering to mod_include to improve performance on
7330 server-side includes. [Marc Slemko]
7332 *) Several fixes for suexec wrapper. [Randy Terbush]
7333 - Make wrapper work for files on NFS filesystem.
7334 - Fix portability problem of MAXPATHLEN.
7335 - Fix array overrun problem in clean_env().
7336 - Fix allocation of PATH environment variable
7338 *) Removed extraneous blank line is description of mod_status chars.
7341 *) Logging of errors from the call_exec routine simply went nowhere,
7342 since the logfile fd has been closed, so now we send them to stderr.
7343 [Harald T. Alvestrand]
7345 *) Fixed core dump when DocumentRoot is a CGI.
7346 [Ben Laurie, reported by geddis@tesserae.com]
7348 *) Fixed potential file descriptor leak in mod_asis; updated it and
7349 http_core to use pfopen/pfclose instead of fopen/fclose.
7350 [Randy Terbush and Roy Fielding]
7352 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
7353 as the DEC Alpha which is 64-bit but uses 32-bit ints.

7356 *) Return a 302 response code to the client when sending a redirect
7357 due to a missing trailing '/' on a directory instead of a 301; now
7358 it is cacheable. [Markus Gyger]
7360 *) Fix condition where, if a bad directive occurs in .htaccess, and
7361 sub_request() goes first to this directory, then log_reason() will
7362 SIGSEGV because it doesn't have initialized r->per_dir_config.
7363 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
7365 *) Fix handling of lang_index in is_variant_better(). This was
7366 causing problems which resulted in the server sending the
7367 wrong language document in some cases. [Petr Lampa]
7369 *) Remove free() from clean_env() in suexec wrapper. This was nuking
7370 the clean environment on some systems.
7372 *) Tweak byteserving code (e.g. serving PDF files) to work around
7373 bugs in Netscape Navigator and Microsoft Internet Explorer.
7374 Emit Content-Length header when sending multipart/byteranges.

7383 given to RLimit* directives. [Ed Korthof]
7385 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
7387 *) Improved buffered output to the client by delaying the flush decision
7388 until the BUFF code is actually about to read the next request.
7389 This fixes a problem introduced in 1.2b5 with clients that send
7390 an extra CRLF after a POST request. Also improved chunked output
7391 performance by combining writes using writev() and removing as
7392 many bflush() calls as possible. NOTE: Platforms without writev()
7393 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
7394 or Configure, unless we have already done so. [Dean Gaudet]
7396 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
7398 *) Fixed mod_info output corruption bug introduced by buffer overflow
7399 fixes. [Dean Gaudet]
7401 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
7402 for the special case of a 304 response. [Paul Sutton]

7417 accept() in child_main(). This change caused the rev to 1.2b6.
7418 1.2b5 was never a public beta.
7420 Changes with Apache 1.2b5
7422 *) Change KeepAlive semantics (On|Off instead of a number), add
7423 MaxKeepAliveRequests directive. [Alexei Kosut]
7425 *) Various NeXT compilation patches, as well as a change in
7426 regex/regcomp.c since that file also used a NEXT define.
7429 *) Allow * to terminate the end of a directory match in mod_dir.
7430 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
7432 *) Don't call can_exec() if suexec_enabled. Calling this requires
7433 scripts executed by the suexec wrapper to be world executable, which
7434 defeats one of the advantages of running the wrapper. [Randy Terbush]
7436 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
7439 *) Migration from sprintf() to snprintf() to avoid buffer
7440 overflows. [Marc Slemko]
7442 *) Provide portable snprintf() implementation (ap_snprintf)
7443 as well as *cvt family. [Jim Jagielski]
7445 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
7448 *) Remove mod_fastcgi.c from the distribution. This module appears
7449 to be maintained more through the Open Market channels and should
7450 continue to be easily available at http://www.fastcgi.com/
7452 *) Fixed bug in modules/Makefile that wouldn't allow building in more
7453 than one subdirectory (or cleaning, either). [Jeremy Laidman]
7455 *) mod_info assumed that the config files were relative to ServerRoot.
7458 *) CGI scripts called as an error document resulting from failed
7459 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
7461 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
7464 *) Properly check errno to prevent display of a directory index
7465 when server receives a long enough URL to confuse stat().
7468 *) Several security enhancements to suexec wrapper. It is _highly_
7469 recommended that previously installed versions of the wrapper
7470 be replaced with this version. [Randy Terbush, Jason Dour]
7472 - ~user execution now properly restricted to ~user's home
7473 directory and below.
7474 - execution restricted to UID/GID > 100
7475 - restrict passed environment to known variables
7476 - call setgid() before initgroups() (portability fix)
7477 - remove use of setenv() (portability fix)
7479 *) Add HTTP/1.0 response forcing. [Ben Laurie]
7481 *) Add access control via environment variables. [Ben Laurie]
7483 *) Add rflush() function. [Alexei Kosut]
7485 *) remove duplicate pcalloc() call in new_connection().
7487 *) Fix incorrect comparison which could allow number of children =
7488 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
7489 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
7491 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
7492 AIX PS/2, CONVEXOS. [Jim Jagielski]
7494 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
7495 It's more portable. [Martin Kraemer]
7497 *) Replace references to make in Makefile.tmpl with $(MAKE).
7500 *) Add ProxyBlock directive w/IP address caching. Add IP address
7501 caching to NoCache directive as well. ProxyBlock works with all
7502 handlers; NoCache now also works with FTP for anonymous logins.
7503 Still more code cleanup. [Chuck Murcko]
7505 *) Add "header parse" API hook [Ben Laurie]
7507 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
7509 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
7511 *) Correctly allow access and auth directives in <Files> sections in
7512 server config files. [Alexei Kosut]
7514 *) Fix bug with ServerPath that could cause certain files to be not
7515 found by the server. [Alexei Kosut]
7517 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
7518 double-quote from text and so that it properly checks for unsupported
7519 status codes using the new index_of_response interface. [Roy Fielding]
7521 *) Multiple fixes to the lingering_close code in order to avoid being
7522 interrupted by a stray timeout, to avoid lingering on a connection
7523 that has already been aborted or never really existed, to ensure that
7524 we stop lingering as soon as any error condition is received, and to
7525 prevent being stuck indefinitely if the read blocks. Also improves
7526 reporting of error conditions. [Marc Slemko and Roy Fielding]
7528 *) Fixed initialization of parameter structure for sigaction.
7529 [mgyger@itr.ch, Adrian Filipi-Martin]
7531 *) Fixed reinitializing the parameters before each call to accept and
7532 select, and removed potential for infinite loop in accept.
7533 [Roy Fielding, after useful PR from adrian@virginia.edu]
7535 *) Fixed condition where, if a child fails to fork, the scoreboard would
7536 continue to say SERVER_STARTING forever. Eventually, the main process
7537 would refuse to start new children because count_idle_servers() will
7538 count those SERVER_STARTING entries and will always report that there
7539 are enough idle servers. [Phillip Vandry]
7541 *) Fixed bug in bcwrite regarding failure to account for partial writes.
7542 Avoided calling bflush() when the client is pipelining requests.
7543 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
7545 *) Added description of "." mode in server-status [Jim Jagielski]
7547 Changes with Apache 1.2b4
7549 *) Fix possible race condition in accept_mutex_init() that
7550 could leave a small security hole open allowing files to be
7551 overwritten in cases where the server UID has write permissions.
7554 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
7556 *) Fix portablity problem in util_script where ARG_MAX may not be
7557 defined for some systems.
7559 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
7562 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
7563 style magic #! token for better script portability. [Garey Smiley]
7565 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
7566 execution for ~userdir CGI. [Jason Dour]
7568 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
7570 *) Fix month off by one in suexec wrapper logging.
7572 Changes with Apache 1.2b3:
7574 *) Fix error in mod_cgi which could cause resources not to be properly
7575 freed, or worse. [Dean Gaudet]
7577 *) Fix find_string() NULL pointer dereference. [Howard Fear]
7579 *) Add set_flag_slot() at the request of Dirk and others.
7582 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
7584 *) Add changes to improve the error message given for invalid
7585 ServerName parameters. [Dirk vanGulik]
7587 *) Add "Authoritative" directive for Auth modules that don't
7588 currently have it. This gives admin control to assign authoritative
7589 control to an authentication scheme and allow "fall through" for
7590 those authentication modules that aren't "Authoritative" thereby
7591 allowing multiple authentication mechanisms to be chained.
7594 *) Remove requirement for ResourceConfig/AccessConfig if not using
7595 the three config file layout. [Randy Terbush]
7597 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
7599 *) Changes to suexec wrapper to fix the following problems:
7600 1. symlinked homedirs will kill ~userdirs.
7601 2. initgroups() on Linux 2.0.x clobbers gr->grid.
7602 3. CGI command lines paramters problems
7603 4. pw-pwdir for "docroot check" still the httpd user's pw record.
7604 [Randy Terbush, Jason Dour]
7606 *) Change create_argv() to accept variable arguments. This fixes
7607 a problem where arguments were not getting passed to the CGI via
7608 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
7610 *) Collapse multiple slashes in path URLs to properly apply
7611 handlers defined by <Location>. [Alexei Kosut]
7613 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
7615 *) Improve the accuracy of request duration timings by setting
7616 r->request_time in read_request_line() instead of read_request().
7619 *) Reset timeout while reading via get_client_block() in mod_cgi.c
7620 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
7622 *) Add the ability to pass different Makefile.tmpl files to Configure
7623 using the -make flag. [Rob Hartill]
7625 *) Fix coredump triggered when sending a SIGHUP to the server caused
7626 by an assertion failure, in turn caused by an uninitialised field in a
7630 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
7631 PATH_INFO from previous versions of Apache (in certain situations,
7632 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
7633 [later removed in 1.2b11]
7635 *) Add rwrite() function to API to allow for sending strings of
7636 arbitrary length. [Doug MacEachern]
7638 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
7640 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
7641 NeXT. [Jim Jagielski]
7643 *) Removed recent modification to promote the status code on internal
7644 redirects, since the correct fix was to change the default log format
7645 in mod_log_config so that it outputs the original status. [Rob Hartill]
7647 Changes with Apache 1.2b2:
7649 *) Update set_signals() to use sigaction() for setting handlers.
7650 This appears to fix a re-entrant problem in the seg_fault()
7651 bus_error() handlers. [Randy Terbush]
7653 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
7655 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
7657 *) proxy_http.c bugfixes: [Chuck Murcko]
7658 1) fixes possible NULL pointer reference w/NoCache
7659 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
7660 host would cache nothing if it was in the local domain,
7661 and the local domain was in the NoCache list)
7662 3) Adds Host: header when not available
7663 4) Some code cleanup and clarification
7665 *) mod_include.c bugfixes:
7666 1) Fixed an ommission that caused include variables to not
7667 be parsed in config errmsg directives [Howard Fear]
7668 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
7669 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
7670 4) Allow backslash-escaping to all quoted text
7671 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
7672 5) Pass variable to command line if not set in XSSI's env
7675 *) Fix infinite loop when processing Content-language lines in
7676 type-map files. [Alexei Kosut]
7678 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
7680 *) Fixed problem in set_[user|group] that prevented CGI execution
7681 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
7683 *) Added PORTING information file. [Jim Jagielski]
7685 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
7687 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
7689 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
7690 USE_FCNTL_SERIALIZED_ACCEPT was intended.
7692 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
7693 which caused problems of systems where socket s_addr is >32bits.
7695 *) Added comment to explain (r->chunked = 1) side-effect in
7696 http_protocol.c [Roy Fielding]
7698 *) Replaced use of index() in mod_expires.c with more appropriate
7699 and portable isdigit() test. [Ben Laurie]
7701 *) Updated Configure for ...
7702 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
7703 *-dg-dgux* (bad pattern match)
7704 QNX (DEF_WANTHSREGEX=yes)
7705 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
7708 and added some user diagnostic info. [Ben Laurie]
7710 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
7711 for better portability. [Jim Jagielski]
7713 *) Updated helpers/GuessOS for ...
7714 SCO 5 (recognize minor releases)
7715 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
7716 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
7717 IRIX64 (-sgi-irix64)
7718 ULTRIX (-unknown-ultrix)
7719 SINIX (-whatever-sysv4)
7720 NCR Unix (-ncr-sysv4)
7721 and fixed something in helpers/PrintPath [Ben Laurie]
7723 Changes with Apache 1.2b1
7725 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
7727 Changes with Apache 1.1.1
7729 *) Fixed bug where Cookie module would make two entries in the
7730 logfile for each access [Mark Cox]
7732 *) Fixed bug where Redirect in .htaccess files would cause memory
7733 leak. [Nathan Neulinger]
7735 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
7737 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
7739 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
7741 Changes with Apache 1.1.0
7743 *) Bring NeXT support up to date. [Takaaki Matsumoto]
7745 *) Bring QNX support up to date. [Ben Laurie]
7747 *) Make virtual hosts default to main server keepalive parameters.
7748 [Alexei Kosut, Ben Laurie]
7750 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
7752 *) Fix missing address family for connect, also remove unreachable statement
7753 in mod_proxy. [Ben Laurie]
7755 *) mod_env now turned on by default in Configuration.tmpl.
7757 *) Bugs which were fixed:
7758 a) yet more mod_proxy bugs [Ben Laurie]
7759 b) CGI works again with inetd [Alexei Kosut]
7760 c) Leading colons were stripped from passwords [osm@interguide.com]
7761 d) Another fix to multi-method Limit problem [jk@tools.de]
7763 Changes with Apache 1.1b4
7765 *) r->bytes_sent variable restored. [Robert Thau]
7767 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
7769 *) More possibly unsecure programs removed from the support directory.
7771 *) More mod_auth_msql authentication improvements.
7773 *) VirtualHosts based on Host: headers no longer conflict with the
7776 *) OS/2 compatibility enhancements. [Gary Smiley]
7778 *) POST now allowed to directory index CGI scripts.
7780 *) Actions now work with files of the default type.
7782 *) Bugs which were fixed:
7783 a) more mod_proxy bugs
7784 b) early termination of inetd requests
7785 c) compile warnings on several systems
7786 d) problems when scripts stop reading output early
7788 Changes with Apache 1.1b3
7790 *) Much of cgi-bin and all of cgi-src has been removed, due to
7791 various security holes found and that we could no longer support
7794 *) The "Set-Cookie" header is now special-cased to not merge multiple
7795 instances, since certain popular browsers can not handle multiple
7796 Set-Cookie instructions in a single header. [Paul Sutton]
7798 *) rprintf() added to buffer code, occurrences of sprintf removed.
7801 *) CONNECT method for proxy module, which means tunneling SSL should work.
7802 (No crypto needed) Also a NoCache config directive.
7804 *) Several API additions: pstrndup(), table_unset() and get_token()
7805 functions now available to modules.
7807 *) mod_imap fixups, in particular Location: headers are now complete
7810 *) New "info" module which reports on installed module set through a
7811 special URL, a la mod_status.
7813 *) "ServerPath" directive added - allows for graceful transition
7814 for Host:-header-based virtual hosts.
7816 *) Anonymous authentication module improvements.
7818 *) MSQL authentication module improvements.
7820 *) Status module design improved - output now table-based. [Ben Laurie]
7822 *) htdigest utility included for use with digest authentication
7825 *) mod_negotiation: Accept values with wildcards to be treated with
7826 less priority than those without wildcards at the same quality
7827 value. [Alexei Kosut]
7829 *) Bugs which were fixed:
7830 a) numerous mod_proxy bugs
7831 b) CGI early-termination bug [Ben Laurie]
7832 c) Keepalives not working with virtual hosts
7833 d) RefererIgnore problems
7834 e) closing fd's twice in mod_include (causing core dumps on
7835 Linux and elsewhere).
7837 Changes with Apache 1.1b2
7840 a) core dumps in mod_digest
7841 b) truncated hostnames/ip address in the logs
7842 c) relative URL's in mod_imap map files
7844 Changes with Apache 1.1b1
7846 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
7848 Changes with Apache 1.0.3
7850 *) Internal redirects which occur in mod_dir.c now preserve the
7851 query portion of a request (the bit after the question mark).
7854 *) Escape active characters '<', '>' and '&' in html output in
7855 directory listings, error messages and redirection links.
7858 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
7860 *) Fix for POSIX compliance in waiting for processes in alloc.c.
7863 *) setsockopt no longer takes a const declared argument [Martijn Koster]
7865 *) Reset timeout timer after each successful fwrite() to the network.
7866 This patch adds a reset_timeout() procedure that is called by
7867 send_fd() to reset the timeout ever time data is written to the net.
7870 *) timeout() signal handler now checks for SIGPIPE and reports
7871 lost connections in a more user friendly way. [Rob Hartill]
7873 *) Location of the "scoreboard" file which used to live in /tmp is
7874 now configurable (for OSes that can't use mmap) via ScoreBoardFile
7875 which works similar to PidFile (in httpd.conf) [Rob Hartill]
7877 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
7879 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
7880 which caused a SEGV with cookies enabled
7882 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
7885 *) Log the UNIX textual error returned by some system calls, in
7886 particular errors from accept() [David Robinson]
7888 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
7890 Changes with Apache 1.0.2
7892 *) patch to get Apache compiled on UnixWare 2.x, recommended as
7893 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
7895 *) Fix get_basic_auth_pw() to set the auth_type of the request.
7898 *) past changes to http_config.c to only use the
7899 setrlimit function on systems defining RLIMIT_NOFILE
7900 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
7901 for SUNOS and prototypes the needed functions.
7903 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
7906 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
7908 *) Merge multiple headers from CGI scripts instead of taking last
7909 one. [David Robinson]
7911 *) Add support for SCO 5. [Ben Laurie]
7913 Changes with Apache 1.0.1
7915 *) Silence mod_log_referer and mod_log_agent if not configured
7918 *) Recursive includes can occur if the client supplies PATH_INFO data
7919 and the server provider uses relative links; as file.html
7920 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
7922 *) The replacement for initgroups() did not call {set,end}grent(). This
7923 had two implications: if anything else used getgrent(), then
7924 initgroups() would fail, and it was consuming a file descriptor.
7927 *) On heavily loaded servers it was possible for the scoreboard to get
7928 out of sync with reality, as a result of a race condition.
7929 The observed symptoms are far more Apaches running than should
7930 be, and heavy system loads, generally followed by catastrophic
7931 system failure. [Ben Laurie]
7933 *) Fix typo in license. [David Robinson]
7935 Changes with Apache 1.0.0 23 Nov 1995
7937 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
7939 Changes with Apache 0.8.16 05 Nov 1995
7941 *) New man page for 'httpd' added to support directory [David Robinson]
7943 *) .htgroup files can have more than one line giving members for a
7944 given group (each must have the group name in front), for NCSA
7945 back-compatibility [Robert Thau]
7947 *) Mutual exclusion around accept() is on by default for SVR4 systems
7948 generally, since they generally can't handle multiple processes in
7949 accept() on the same socket. This should cure flaky behavior on
7950 a lot of those systems. [David Robinson]
7952 *) AddType, AddEncoding, and AddLanguage directives take multiple
7953 extensions on a single command line [David Robinson]
7955 *) UserDir can be disabled for a given virtual host by saying
7956 "UserDir disabled" in the <VirtualHost> section --- it was a bug
7957 that this didn't work. [David Robinson]
7959 *) Compiles on QNX [Ben Laurie]
7961 *) Corrected parsing of ctime time format [David Robinson]
7963 *) httpd does a perror() before exiting if it can't log its pid
7964 to the PidFile, to make diagnosing the error a bit easier.
7967 *) <!--#include file="..."--> can no longer include files in the
7968 parent directory, for NCSA back-compatibility. [David Robinson]
7970 *) '~' is *not* escaped in URIs generated for directory listings
7973 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
7975 *) Fixed bug involving handling URIs with escaped %-characters
7976 in redirects [David Robinson]
7978 Changes with Apache 0.8.15 14 Oct 1995
7980 *) Switched to new, simpler license
7982 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
7984 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
7986 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
7988 *) Correctly handles internal redirects to files with names containing '%'
7991 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
7993 *) Use geteuid() rather than getuid() to see if we have root privilege,
7994 so that server correctly resets privilege if run setuid root. [Andrew
7997 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
8000 *) Fix relative URLs in imagemap files [Randy Terbush]
8002 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
8005 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
8006 entries all name the same one. [David Robinson]
8008 *) Fix directory listings with filenames containing unusual characters
8011 *) Better URI-escaping for generated URIs in directories with filenames
8012 containing unusual characters [Ben Laurie]
8014 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
8016 *) Unblock alarms on error return from spawn_child() [David Robinson]
8018 *) Sample Config files have extra note for SCO users [Ben Laurie]
8020 *) Configuration has note for HP-UX users [Rob Hartill]
8022 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
8024 *) Nuked bogus #define in httpd.h [David Robinson]
8026 *) Better test for whether a system has setrlimit() [David Robinson]
8028 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
8030 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
8033 Changes with Apache 0.8.14 19 Sep 1995
8035 *) Compiles on SCO ODT 3.0 [Ben Laurie]
8037 *) AddDescription works (better) [Ben Laurie]
8039 *) Leaves an intelligible error diagnostic when it can't set group
8040 privileges on standalone startup [Andrew Wilson]
8042 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
8043 that machine, which claims to be BSD but does not support RLIMIT.
8046 *) gcc -Wall no longer complains about an unused variable when util.c
8047 is compiled with -DMINIMAL_DNS [Andrew Wilson]
8049 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
8051 Changes with Apache 0.8.13 07 Sep 1995
8053 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
8055 *) Have built-in imagemap code recognize & honor Point directive [James
8058 *) Generate cleaner directory listings in directories with a mix of
8059 long and short filenames [Rob Hartill]
8061 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
8063 *) Properly default ServerName for virtual servers [Robert Thau]
8065 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
8066 Paul Richards and a cast of thousands...]
8068 *) On self-identified BSD systems (we don't try to guess any more),
8069 allocate a few extra file descriptors per virtual host with setrlimit,
8070 if we can, to avoid running out. [Randy Terbush]
8072 *) Write 22-character lock file name into buffer with enough space
8073 on startup [Konstantin Olchanski]
8075 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
8078 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
8080 *) Suppress -Wall warning by initializing variable in negotiation code
8081 [Tobias Weingartner]
8083 Changes with Apache 0.8.12 31 Aug 1995
8085 *) Doesn't pause three seconds after including a CGI script which is
8086 too slow to die off (this is done by not even trying to kill off
8087 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
8088 after the entire document has been processed). [Robert Thau]
8090 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
8092 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
8094 *) Allows .htaccess files to override <Directory> sections naming the
8095 same directory [David Robinson]
8097 *) Removed an efficiency hack in sub_req_lookup_uri which was
8098 causing certain extremely marginal cases (e.g., ScriptAlias of a
8099 *particular* index.html file) to fail. [David Robinson]
8101 *) Doesn't log an error when the requested URI requires
8102 authentication, but no auth header line was supplied by the
8103 client; this is a normal condition (the client doesn't no auth is
8104 needed here yet). [Robert Thau]
8106 *) Behaves more sanely when the name server loses its mind [Sean Welch]
8108 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
8110 *) RFC931 code no longer passes out name of prior clients on current
8111 requests if the current request came from a server that doesn't
8112 do RFC931. [David Robinson]
8114 *) Configuration script accepts "Module" lines with trailing whitespace.
8117 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
8119 *) Cleaned up comments in mod_cgi.c [Robert Thau]
8121 Changes with Apache 0.8.11 24 Aug 1995
8123 *) Wildcard <Directory> specifications work. [Robert Thau]
8125 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
8127 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
8128 the file being requested itself, in addition to the directories leading
8129 up to it. [Robert Thau]
8131 *) Logs access failures due to symlink checks or invalid client address
8132 in the error log [Roy Fielding, Robert Thau]
8134 *) Symlink checks deal correctly with systems where lstat of
8135 "/path/to/some/link/" follows the link. [Thau, Fielding]
8137 *) Doesn't reset DirectoryIndex to 'index.html' when
8138 other directory options are set in a .htaccess file. [Robert Thau]
8140 *) Clarified init code and nuked bogus warning in mod_access.c
8143 *) Corrected several directives in sample srm.conf
8144 --- includes corrections to directory indexing icon-related directives
8145 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
8146 icons for encodings right, and turning on AddEncoding by default).
8149 *) Corrected descriptions of args to AddIcon and AddAlt in command table
8152 *) INSTALL & README mention "contributed modules" directory [Brian
8155 *) Fixed English in the license language... "for for" --> "for".
8158 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
8159 mod_alias.c, merging it almost completely with handling of Alias, and
8160 adding a 'notes' field to the request_rec which allows the CGI module
8161 to discover whether the Alias module has put this request through
8162 ScriptAlias (which it needs to know for back-compatibility, as the old
8163 NCSA code did not check Options ExecCGI in ScriptAlias directories).
8166 Changes with Apache 0.8.10 18 Aug 1995
8168 *) AllowOverride applies to the named directory, and not just
8169 subdirectories. [David Robinson]
8171 *) Do locking for accept() exclusion (on systems that need it)
8172 using a special file created for the purpose in /usr/tmp, and
8173 not the error log; using the error log causes real problems
8174 if it's NFS-mounted; this is known to be the cause of a whole
8175 lot of "server hang" problems with Solaris. [David Robinson;
8176 thanks to Merten Schumann for help diagnosing the problem].
8178 Changes with Apache 0.8.9 12 Aug 1995
8180 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
8182 *) Nested includes see environment variables of the including document,
8183 for NCSA bug-compatibility (some sites have standard footer includes
8184 which try to print out the last-modified date). [Eric Hagberg/Robert
8187 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
8188 URI as a CGI script, even if it would have been treated as something
8189 else if requested directly, for NCSA back-compatibility. (Note that
8190 this means that people who know the name of the script can see the
8191 code just by asking for it). [Robert Thau]
8193 *) New version of dbmmanage script included in support directory as
8196 *) Check if scoreboard file couldn't be opened, and say so, rather
8197 then going insane [David Robinson]
8199 *) POST to CGI works on A/UX [Jim Jagielski]
8201 *) AddIcon and AddAlt commands work properly [Rob Hartill]
8203 *) NCSA server push works properly --- the Arena bug compatibility
8204 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
8205 if you still want the workaround). [Rob Hartill]
8207 *) If client didn't submit any Accept-encodings, ignore encodings in
8208 content negotiation. (NB this will all have to be reworked anyway
8209 for the new HTTP draft). [Florent Guillaume]
8211 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
8213 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
8215 *) Give Redirect priority over Alias, for NCSA bug compatibility
8218 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
8219 paralleling earlier bug fix for CGI [David Robinson]
8221 *) If DBM auth is improperly configured, report a server error and don't
8224 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
8225 it seems to work well enough without it (even in a 10 hits/sec
8226 workout), and the overhead for the locking under A/UX is
8227 alarmingly high (though it is very low on other systems).
8228 [Eric Hagberg, Jim Jagielski]
8230 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
8232 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
8233 Behlendorf/Eric Hagberg]
8235 *) More improvements to default Configuration for A/UX [Jim Jagielski]
8237 *) Compiles clean on NEXT [Rob Hartill]
8239 *) Compiles clean on SGI [Robert Thau]
8241 Changes with Apache 0.8.8 08 Aug 1995
8243 *) SunOS library prototypes now never included unless explicitly
8244 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
8245 people using GNU libc on SunOS are screwed by prototypes for the
8248 (Those who wish to compile clean with gcc -Wall on a standard
8249 SunOS setup need the prototypes, and may obtain them using
8250 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
8251 with nonstandard libraries are presumably competent to make their
8254 *) Strips trailing '/' characters off both args to the Alias command,
8255 to make 'Alias /foo/ /bar/' work.
8257 Changes with Apache 0.8.7 03 Aug 1995
8259 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
8260 [reported by David Robinson]
8262 *) Compiles clean on OSF/1 [David Robinson]
8264 *) Added some of the more recent significant changes (AddLanguage stuff,
8265 experimental LogFormat support) to CHANGES file in distribution root
8268 Changes with Apache 0.8.6 02 Aug 1995
8270 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
8271 (If you actually wanted a conditional GET which bypassed the cache, you
8272 couldn't get it). [Reported by Roy Fielding]
8274 *) Properly terminate headers on '304 Not Modified' replies to conditional
8275 GETs --- no browser we can find cares much, but the CERN proxy chokes.
8276 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
8278 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
8280 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
8281 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
8282 and older versions don't set the __SUNPRO_C preprocessor variable). On
8283 all other systems, these are never used anyway. [Reported by Mark Cox].
8285 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
8287 Changes with Apache 0.8.5 01 Aug 1995
8289 *) Added last-minute configurable log experiment, as optional module
8291 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
8292 properly. (One-line fix to http_protocol.c).
8294 *) Work around bogus behavior when reloading from Netscape.
8295 It's Netscape's bug --- for some reason they expect a request with
8296 If-modified-since: to not function as a conditional GET if it also
8297 comes with Pragma: no-cache, which is way out of line with the HTTP
8298 spec (according to Roy Fielding, the redactor).
8300 *) Added parameter to set maximum number of server processes.
8302 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
8305 *) IdentityCheck bugfix [Chuck Murcko].
8307 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
8309 *) More sample config file corrections; add extension to AddType for
8310 *.asis, move AddType generic description to its proper place, and
8311 fix miscellaneous typos. [ Alexei Kosut ]
8313 *) Deleted the *other* reference to the regents from the Berkeley
8314 legal disclaimer (everyplace).
8316 *) Nuked Shambhala name from src/README; had already cleaned it out
8319 Changes with Apache 0.8.4
8321 *) Changes to server-pool management parms --- renamed current
8322 StartServers to MinSpareServers, created separate StartServers
8323 parameter which means what it says, and renamed MaxServers to
8324 MaxSpareServers (though the old name still works, for NCSA 1.4
8325 back-compatibility). The old names were generally regarded as
8326 too confusing. Also altered "docs" in sample config files.
8328 *) More improvements to default config files ---
8329 sample directives (commented out) for XBitHack, BindAddress,
8330 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
8331 defaults, AddTypes for send-as-is and imagemap magic types, and
8332 improvements to samples for DirectoryIndex [Alexei Kosut]
8334 *) Yet more improvements to default config files --- changes to
8335 Alexei's sample AddLanguage directives, and sample LanguagePriority
8336 [ Florent Guillaume ]
8338 *) Set config file locations properly if not set in httpd.conf
8341 *) Don't escape URIs in internal redirects multiple times; don't
8342 do that when translating PATH_INFO to PATH_TRANSLATED either.
8345 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
8347 Changes with Apache 0.8.3
8349 *) Edited distribution README to *briefly* summarize installation
8350 procedures, and give a pointer to the INSTALL file in the src/
8353 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
8354 recent NCSA distributions.
8356 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
8357 exist for the same directory, use both and don't segfault. [Reported
8360 *) Proper makefile dependencies [David Robinson]
8362 *) Note (re)starts in error log --- reported by Rob Hartill.
8364 *) Only call no2slash() after get_path_info() has been done, to
8365 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
8366 reported by Andrew Wilson, though this one is probably a real bug]
8368 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
8369 dump core when Referer is not supplied. [Randy Terbush]
8371 *) Lightly edited sample config files to refer people to our documentation
8372 instead of NCSA's, and to list Rob McCool as *original* author (also
8373 deleted his old, and no doubt non-functional email address). Would be
8374 nice to have examples of new features...
8376 Changes with Apache 0.8.2 19 Jul 1995
8378 *) Added AddLanuage code [Florent Guillaume]
8380 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
8382 *) All sorts of problems when MultiViews finds a directory. It would
8383 be nice if mod_dir.c was robust enough to handle that, but for now,
8384 just punt. [reported by Brian Behlendorf]
8386 *) Wait for all children on restart, to make sure that the old socket
8387 is gone and we can reopen it. [reported by Randy Terbush]
8389 *) Imagemap module is enabled in default Configuration
8391 *) RefererLog and UserAgentLog modules properly default the logfile
8394 *) Mark Cox's mod_cookies added to the distribution as an optional
8395 module (commented out in the default Configuration, and noted as
8396 an experiment, along with mod_dld). [Mark Cox]
8398 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
8400 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
8402 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
8404 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
8407 Changes with Apache 0.8.1
8409 *) New imagemap module [Randy Terbush]
8411 *) Replacement referer log module with NCSA-compatible RefererIgnore
8412 [Matthew Gray again]
8414 *) Don't mung directory listings with very long filenames.
8417 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
8419 *) New config script. See INSTALL for info. [Robert Thau]
8421 *) Scoreboard mechanism for regulating the number of extant server
8422 processes. MaxServers and StartServers defaults are the same as
8423 for NCSA, but the meanings are slightly different. (Actually,
8424 I should probably lower the MaxServers default to 10).
8426 Before asking for a new connection, each server process checks
8427 the number of other servers which are also waiting for a
8428 connection. If there are more than MaxServers, it quietly dies
8429 off. Conversely, every second, the root, or caretaker, process
8430 looks to see how many servers are waiting for a new connection;
8431 if there are fewer than StartServers, it starts a new one. This
8432 does not depend on the number of server processes already extant.
8433 The accounting is arranged through a "scoreboard" file, named
8434 /tmp/htstatus.*, on which each process has an independent file
8435 descriptor (they need to seek without interference).
8437 The end effect is that MaxServers is the maximum number of
8438 servers on an *inactive* server machine, but more will be forked
8439 off to handle unusually heavy loads (or unusually slow clients);
8440 these will die off when they are no longer needed --- without
8441 reverting to the overhead of full forking operation. There is a
8442 hard maximum of 150 server processes compiled in, largely to
8443 avoid forking out of control and dragging the machine down.
8444 (This is arguably too high).
8446 In my server endurance tests, this mechanism did not appear to
8447 impose any significant overhead, even after I forced it to put the
8448 scoreboard file on a normal filesystem (which might have more
8449 overhead than tmpfs). [Robert Thau]
8451 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
8454 *) Read .htaccess files even in directory with <Directory> section.
8455 (Former incompatibility noted on mailing list, now fixed). [Robert
8458 *) "HEAD /" gives the client a "Bad Request" error message, rather
8459 than trying to send no body *and* no headers. [Cliff Skolnick].
8461 *) Don't produce double error reports for some very obscure cases
8462 mainly involving auth configuration (the "all modules decline to
8463 handle" case which is a sure sign of a server bug in most cases,
8464 but also happens when authentication is badly misconfigured).
8467 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
8468 it's *for*, and this sort of thing really shouldn't be cluttering
8469 up the Makefile). [Robert Thau]
8471 *) Incidental code cleanups in http_main.c --- stop dragging
8472 sa_client around; just declare it where used. [Robert Thau]
8474 *) Another acc-related fix. (It doesn't like const char
8475 in some places...). [Mark Cox]
8477 Changes with Shambhala 0.6.1 13 Jul 1995
8479 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
8480 Also, fixed auth typo in http_protocol.c unmasked by this fix.
8482 *) Compiles clean with acc on SunOS [Paul Sutton]
8484 *) Reordered modules in modules.c so that Redirect takes priority
8485 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
8486 believe it or not, he has an actual site with a ScriptAlias and
8487 a Redirect declared for the *exact same directory*. Even *my*
8488 compatibility fetish wouldn't motivate me to fix this if the fix
8489 required any effort, but it doesn't, so what the hey.
8491 *) Fixed to properly default several server_rec fields for virtual
8492 servers from the corresponding fields in the main server_rec.
8493 [Cliff Skolnick --- 'port' was a particular irritant].
8495 *) No longer kills off nph- child processes before they are
8496 finished sending output. [Matthew Gray]
8498 Changes with Shambhala 0.6.0 10 Jul 1995
8500 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
8501 the connection to the client in an "aborted" state, but otherwise
8502 allow whatever handlers are running to clean up. hard_timeout()s
8503 abort the request in progress completely; anything not tied to some
8504 resource pool cleanup will leak. They're still around because I
8505 haven't yet come up with a more elegant way of handling
8506 timeouts when talking to something that isn't the client. The
8507 default_handler and the dir_handler now use soft timeouts, largely
8508 so I can test the feature. [Robert Thau]
8510 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
8511 the case of log handlers dying prematurely is probably handled VERY
8512 gracelessly at this point, and if the logger stops reading input,
8513 the server will hang. (It is known to correctly restart the
8514 logging process on server restart; this is (should be!) going through
8515 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
8516 script). [Robert Thau]
8518 *) asis files supported (new module). [Robert Thau]
8520 *) IdentityCheck code is compiled in, but has not been tested. (I
8521 don't know anyone who runs identd). [Robert Thau]
8523 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
8524 came in with the request, for NCSA bug-compatibility. [Robert Thau]
8526 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
8528 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
8529 as timeouts are not in scope. [Robert Thau]
8531 *) quoted-string args in config files now handled correctly (doesn't drop
8532 the last character). [Robert Thau; reported by Randy Terbush]
8534 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
8535 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
8537 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
8538 default default type); the former default default behavior when all
8539 type-checkers defaulted had been a core dump. [Paul Sutton]
8541 *) Copy filenames out of the struct dirent when indexing
8542 directories. (On Linux, readdir() returns a pointer to the same
8543 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
8545 Changes with Shambhala 0.5.3 [not released]
8547 *) Default response handler notes "file not found" in the error log,
8548 if the file was not found. [Cliff Skolnick].
8550 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
8551 code no longer sets up bogus PATH_INFO which fakes out the directory
8552 handler). [Cliff Skolnick]
8554 Changes with Shambhala 0.5.2 06 Jul 1995
8556 *) Changes to http_main.c --- root server no longer plays silly
8557 games with SIGCHLD, and so now detects and replaces dying
8558 children. Child processes just die on SIGTERM, without taking
8559 the whole process group with them. Potential problem --- if any
8560 child process refuses to die, we hang in restart.
8561 MaxRequestsPerChild may still not work, but it certainly works
8562 better than it did before this! [Robert Thau]
8564 *) mod_dir.c bug fixes: ReadmeName and HeaderName
8565 work (or work better, at least); over-long description lines
8566 properly terminated. [Mark Cox]
8568 *) http_request.c now calls unescape_url() more places where it
8569 should [Paul Sutton].
8571 *) More directory handling bugs (reported by Cox)
8572 Parent Directory link is now set correctly. [Robert Thau]
8574 Changes with Shambhala 0.5.1 04 Jul 1995
8576 *) Generalized cleanup interface in alloc.c --- any function can be
8577 registered with alloc.c as a cleanup for a resource pool;
8578 tracking of files and file descriptors has been reimplemented in
8579 terms of this interface, so I can give it some sort of a test.
8582 *) More changes in alloc.c --- new cleanup_for_exec() function,
8583 which tracks down and closes all file descriptors which have been
8584 registered with the alloc.c machinery before the server exec()s a
8585 child process for CGI or <!--#exec-->. CGI children now get
8586 started with exactly three file descriptors open. Hopefully,
8587 this cures the problem Rob H. was having with overly persistent
8588 CGI connections. [Robert Thau]
8590 *) Mutual exclusion around the accept() in child_main() --- this is
8591 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
8592 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
8593 This uses fcntl(F_SETLK,...) on the error log descriptor because
8594 flock() on that descriptor won't work on systems which have BSD
8595 flock() semantics, including (I think) Linux 1.3 and Solaris.
8597 This does work on SunOS (when the server is idle, only one
8598 process in the pool is waiting on accept()); it *ought* to work
8599 on the other systems. [Robert Thau]
8601 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
8603 *) sizeof(*sa_client) bugfix from [Rob Hartill]
8605 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
8607 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
8608 be unnecessary if I go to the revised timeout-handling scheme).
8611 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
8612 string) even if none came in with the request. [Robert Thau]
8614 *) CHANGES file added to distribution ;-).
8616 Changes with Shambhala 0.4.5
8618 *) mod_dld --- early dynamic loading support [rst]
8619 *) Add wildcard content handlers for XBITHACK; default_hander now
8620 invoked with that mechanism (as a handler hanging off mod_core) [rst]
8621 *) XBITHACK supported as a wildcard content-handler, and
8622 configurable at run-time (not just at compile time, as in the
8623 "patchy server" releases) [rst]
8625 Changes with Shambhala 0.4.4 30 Jun 1995
8627 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
8628 *) Handle Addtype x/y .z [rst, reported by Cox]
8630 Changes with Shambhala 0.4.3
8632 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
8633 synonymous [rst, terbush]
8635 Changes with Shambhala 0.4.1 28 Jun 1995
8637 *) First-cut virtual host implementation; some refit in the config
8638 reading code, and log management, was necessary to support this [rst]
8639 *) Sub-pool machinery, originally added to avoid excessive storage
8640 allocation on listings of large directories (which turned out to
8641 be the problem that the 0.3 storage accounting was added to
8642 find). Subrequests and mod_dir changed to use subpools. [rst]
8643 *) More memory debugging --- free list consistency checks. [rst]
8644 *) Added err_headers to request_rec, with support elsewhere [rst]
8645 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
8647 Changes with Shambhala 0.3 19 Jun 1995
8649 *) Switch ONE_PROCESS to a runtime command-line option (-X)
8650 *) Don't compile in mod_ai_backcompat by default
8651 *) Switch name of server from Apache to Shambhala in Makefile
8652 *) Add some accounting routines to track memory usage in the pools,
8655 Changes with Shambhala 0.2
8657 *) Set DOCUMENT_ROOT CGI variable
8658 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
8659 *) Add critical section protection to handling of cleanup structures
8661 *) Significant code reorg within the server core to group related
8662 functions together [rst]
8663 *) Correctly handle clients that hang up before sending any request
8665 *) Replace dying child processes. [rst]
8667 Changes with Shambhala 0.1 12 Jun 1995
8669 Major rewrite of the pre-existing "patchy server" codebase, by
8670 Robert Thau (rst). Significant portions of the server code, such
8671 as configuration-file handling and HTTP authentication support,
8672 were ripped out and rewritten from scratch. Code that was not
8673 completely rewritten was significantly altered.
8675 Major changes with this release include:
8677 *) Introduction of the module API; in request handling, the central
8678 machinery just dispatches to various modules, which actually do
8679 most of the work. Configuration handling is similar --- modules
8680 declare their own commands, and the central machinery just
8683 API features from shambhala/0.1 were substantially unchanged in
8684 Apache 1.0 and 1.1. (1.0 API features not yet present in this
8685 release, such as wildcard handlers and subpools, were added in
8686 subsequent Shambhala releases, and were also generally rst's
8689 *) This release included the following modules:
8691 mod_access (access control --- allow and deny directives),
8692 mod_alias (Alias and Redirect commands),
8693 mod_auth (straight HTTP authentication, based on flat-files)
8694 mod_auth_dbm (same, with dbm files)
8695 mod_cgi (CGI scripts and, in this release, ScriptAlias)
8696 mod_common_log (CLF access logs; later renamed mod_log_common)
8697 mod_dir (directory indexing)
8698 mod_include (server-side includes)
8699 mod_mime (AddType directives)
8700 mod_negotiation (content negotiation)
8701 mod_userdir (support for users' public_html directories)
8703 It also included a mod_ai_backcompat, which was a private hack
8704 for back-compatibility with rst's own AI-lab servers.
8706 All of these modules were substantially complete, and functional
8707 or nearly so (a few, which implemented features not in use at
8708 Thau's site, required patches of a few lines).
8710 *) sub-request machinery, to allow modules to determine how other
8711 modules would assign MIME types to a given file, or optionally
8712 serve its content (this is heavily used by mod_dir, mod_include
8713 and mod_negotiation).
8715 *) Resource pool system for keeping track of memory allocated and
8716 files opened in service of a particular request. Much of the
8717 code in the modules (when they weren't rewrites) was adjusted to
8718 replace a pervasive convention of using fixed-size buffers on
8719 the stack with an equally pervasive convention of using memory
8720 allocated with palloc().
8722 *) Reorganization of data structures associated with a given
8723 request to eliminate use of global variables and the troublesome
8724 unmunge_name function (used in NCSA and early Apache releases to
8725 attempt to determine the URI which mapped to a given filename
8726 --- a difficult proposition, given that it is easy to produce
8727 setups in which multiple URIs map to the same file).
8729 *) Source files renamed and rearranged
8731 *) Very simple pre-forking behavior --- parent process forked off a
8732 fixed number of children, and then just waited for SIGHUP.
8734 *) Other more minor changes too numerous to list.
8736 This release included modified versions of a lot of code from the
8737 Apache 0.6.4 public release, plus an early pre-forking patch
8738 codeveloped by Robert Thau and Rob Hartill.
8740 Changes with Apache 0.7.3 20 Jun 1995
8742 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
8743 were incorporated by Rob Hartill on the main branch while Robert Thau
8744 worked on the Shambhala rewrite above. Most were merged into the
8745 Shambala architecture after Apache 0.8.0.
8747 Changes with Apache 0.6.4 13 May 1995
8749 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
8752 Changes with Apache 0.5.1 10 Apr 1995

8756 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
8759 Changes with Apache 0.3 24 Mar 1995
8761 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
8764 Changes with Apache 0.2 18 Mar 1995
8766 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
8767 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
8768 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
