1 Changes with Apache 2.0b1
3 *) We have a poor abstraction in the protocol. This is a temporary
4 hack to fix the bug, but it will need to be fixed for real. If
5 we find an error while sending out a custom error response, we back
6 up to the first non-OK request and send the data. Then, when we send
7 the EOS from finalize_request_protocol, we go to the last request,
8 to ensure that we aren't sending an EOS to a request that has already
9 received one. Because the data is sent on a different request than
10 the EOS, the error text never gets sent down the filter stack. This
11 fixes the problem by finding the last request, and sending the data
12 with that request. [Ryan Bloom]
14 *) Make the server status page show the correct restart time, and
15 thus the proper uptime. [Ryan Bloom]
17 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
18 should reduce the amount of duplicate code that is required to
20 [Paul J. Reder <rederpj@raleigh.ibm.com>]
22 *) ap_new_connection() closes the socket and returns NULL if a socket
23 call fails. Usually this is due to a connection which has been
26 *) Move the Apache version information out of httpd.h and into release.h.
27 This is in preparation for the first tag with the new tag and release
30 *) Begin restructuring scoreboard code to enable adding back in
31 the ability to use IPC other than shared memory.
32 Get mod_status working on Windows again. [Bill Stoddard]
34 *) Make mod_status work with 2.0. This will work for prefork,
35 mpmt_pthread, and dexter. [Ryan Bloom]
37 *) Correct a typo in httpd.conf.
38 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
40 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
42 *) Get the correct IP address if ServerName isn't set and we can't
43 find a fully-qualified domain name at startup.
44 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
46 *) Make mod_cgid work with SuExec. [Ryan Bloom]
48 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
49 'extra' stat's for user/group since they should never occur, and now
50 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
51 volumes. [William Rowe]
53 *) Adopt apr features to simplify mod_includes. This changes the
54 behavior of the USER_NAME variable, unknown uid's are now reported
55 as USER_NAME="<unknown>" rather than the old user#000 result.
56 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
58 *) Adopt apr features for simplifing mod_userdir, and accept the new
59 Win32/OS2 exceptions without hiccuping. [William Rowe]
61 *) Replace configure --with-optim option by using and saving the
62 environment variable OPTIM instead. This is needed because configure
63 options do not support multiple flags separated by spaces.
66 *) Fix some byterange handling. If we get a byte range that looks like
67 "-999999" where that is past the end of the file, we should return
68 a PARTIAL CONTENT status code, and return the whole file as one big
69 byterange. This matches the 1.3 handling now. [Ryan Bloom]
71 *) Make the error bucket a real meta-data bucket. This means that the
72 bucket length is 0, and a read returns NULL data. If one of these
73 buckets is passed down after the headers are sent, this data will
74 just be ignored. [Greg Stein]
76 *) The prefork MPM wasn't killing child processes correctly if a restart
77 signal was received while the process was serving a request. The child
78 process would become the equivalent of a second parent process. If
79 we break out of the accept loop, then we need to do die after cleaning
80 up after ourselves. [Ryan Bloom]
82 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
83 restarts. [Ryan Bloom]
85 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
86 the most optimal APR_FINFO_wanted bits. This spares Win32 from
87 performing very expensive owner, group and permission lookups
88 and allows the server to function until these apr_finfo_t fields
89 are implemented under Win32. [William Rowe]
91 *) Support for typedsafe optional functions - that is functions exported by
92 optional modules, which, therefore, may or may not be present, depending
93 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
94 for sample code. [Ben Laurie]
96 *) filters can now report an HTTP error to the server. This is done
97 by sending a brigade where the first bucket is an error_bucket.
98 This bucket is a simple bucket that stores an HTTP error and
99 a string. Currently the string is not used, but it may be needed
100 to output an error log. The http_header_filter will find this
101 bucket, and output the error text, and then return
102 AP_FILTER_ERROR, which informs the server that the error web page
103 has already been sent. [Ryan Bloom]
105 *) If we get an error, then we should remove all filters except for
106 those critical to serving a web page. This fixes a bug, where
107 error pages were going through the byterange filter, even though
108 that made no sense. [Ryan Bloom]
110 *) Relax the syntax checking of Host: headers in order to support
111 iDNS. PR#6635 [Tony Finch]
113 *) Cleanup the byterange filter to use the apr_brigade_partition
114 and apr_bucket_copy functions. This removes a lot of very messy
115 code, and hopefully makes this filter more stable.
118 *) Remove AddModule and ClearModuleList directives. Both of these
119 directives were used to ensure that modules could be enabled
120 in the correct order. That requirement is now gone, because
121 we use hooks to ensure that modules are in the correct order.
124 *) When SuExec is specified, we need to add it to the list of
125 targets to be built. If we don't, then any changes to the
126 configuration won't affect SuExec, unless 'make suexec' is
127 specifically run. [Ryan Bloom]
129 *) Cleaned out open_file from mod_file_cache, as apr now accepts
130 the APR_XTHREAD argument to open a file for consumption by
131 parallel threads on win32. [William Rowe]
133 *) Correct a bug in determining when we follow symlinks. The code
134 expected a stat -1 result, not an apr_status_t positive error.
135 Also check if the APR_FINFO_USER fields are valid before we
136 follow the link. [William Rowe]
138 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
139 mpm_common.c. These functions are only valid on some platforms,
140 so they should not be in the main-line code. [Ryan Bloom]
142 *) Remove ap_chdir_file(). This function is not thread-safe,
143 and nobody is currently using it. [Ryan Bloom]
145 *) Do not try to run make depend if there are no .c files in the
146 current directory, doing so makes `make depend` fail.
149 *) Update highperformance.conf to work with either prefork or
150 pthreads mpms. [Greg Ames]
152 *) Stop checking to see if this is a pipelined request if we know
153 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
154 This keeps us from making an extra read call when serving a 1.0
155 request. [Ryan Bloom and Greg Stein]
157 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
158 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
159 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
161 *) Fix the RFC number mentioned when complaining about a missing
162 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
164 *) Fix an endless loop in ab which occurred when ab was posting
165 and the server dropped the connection unexpectedly.
168 *) Fix a segfault while handling request bodies in ap_http_filter().
169 This problem has been seen with mod_dav usage as well as with
170 requests where the body was just being discarded. [Jeff Trawick]
172 *) Some adjustment on the handling and automatic setting (via
173 hints.m4) of various compilation flags (eg: CFLAGS). Also,
174 add the capability to specify flags (NOTEST_CFLAGS and
175 NOTEST_LDFLAGS) which are used to compile Apache, but
176 not used during the configuration process. Useful for
177 flags like "-Werror". [Jim Jagielski]
179 *) Stop using environment variables to force debug mode or
180 no detach. We now use the -D command line argument to
181 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
182 [Greg Stein, Ryan Bloom]
184 *) Change handlers to use hooks. [Ben Laurie]
186 *) Stop returning copies of filenames from both apr_file_t and
187 apr_dir_t. We pstrdup the filenames that we store in the
188 actual structures, so we don't need to pstrdup the strings again.
191 *) mod_cgi: Fix some problems where the wrong error value was being
192 traced. [Jeff Trawick]
194 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
197 *) Add generic hooks. [Ben Laurie]
199 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
201 *) Fix a segfault caused by mod_ext_filter when the external filter
202 program does not exist. [Jeff Trawick]
204 *) Fix an output truncation error when on an HTTP >= 1.0 request an
205 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
206 was served through mod_charset_lite (or anything else that would
207 create a transient bucket in this size range). ap_bucket_make_heap()
208 silently failed (fixed), transient_setaside() discovered it, but
209 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
211 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
212 is that some browsers send extra lines at the end of POST requests, and
213 we don't want to delay sending data back to the user just because the
214 browser isn't well behaved. [Ryan Bloom]
216 *) Get SuEXEC working again. We can't send absolute paths to suExec
217 because it refuses to execute those programs. SuEXEC also wasn't
218 always recognizing configuration changes made using the autoconf
221 *) Allow the buildconf process to find the config.m4 files in the correct
222 order. Basically, we can now name config.m4 files as config\d\d.m4,
223 and we will sort them correctly when inserting them into the build
224 process. [Ryan Bloom]
226 *) Get mod_cgid to use apr calls for creating the actual CGI process.
227 This also allows mod_cgid to use ap_os_create_priviledged_process,
228 thus allowing for SuExec execution from mod_cgid. Currently, we do
229 not support everything that standard SuExec supports, but at least
230 it works minimally now. [Ryan Bloom]
232 *) Allow SuExec to be configured from the ./configure command line.
235 *) Update some of the docs in README and INSTALL to reflect some of
236 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
238 *) If we get EAGAIN returned from the call to apr_sendfile, then we
239 need to call sendfile again. This gets us serving large files
240 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
242 *) Get the support programs building cleanly again.
243 [Cliff Woolley <cliffwoolley@yahoo.com>]
245 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
246 current directory logic now backs up over bin/ to determine the
247 server root from the Apache.exe path.
249 *) Apache/Win32 now follows the standard conventions of mod_foo.so
250 loadable modules, dynamic libs are all named libfoo.dll, and the
251 makefile.win populates the include, lib and libexec directories.
253 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
254 Apache gets IPv6 listening sockets by default. Additionally, the
255 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
256 numeric address strings (e.g., "Listen [fe80::1]:8080").
259 *) Modify the install directory layout. Modules are now installed in
260 modules/. Shared libraries should be installed in libraries/, but
261 we don't have any of those on Unix yet. All install directories
262 are modifyable at configure time. [Ryan Bloom]
264 *) Install all header files in the same directory on Unix. [Ryan Bloom]
266 *) Get the functions in server/linked into the server, regardless of
267 which modules linked into the server. This uses the same hack
268 for Apache that we use for APR and apr-util to ensure all of the
269 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
270 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
271 the scripts a bit easier.
274 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
275 on the query, and remove IPv4 dependencies. [Jeff Trawick]
277 *) Get all of the auth modules to the point that they will install and
278 be loadable into the server. Our new build/install mechanism expects
279 that all modules will have a common name format. The auth modules
280 didn't use that format, so we didn't install them properly.
283 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
284 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
286 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
288 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
289 after the end of the response. [Ryan Bloom]
291 *) Get byterange requests working with responses that do not have a
292 content-length. Because of the way byterange requests work, we have to
293 have all of the data before we can actually do the byterange, so we
294 can compute the content-length in the byterange filter.
297 *) Get exe CGI's working again on Windows.
300 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
301 they keep track of whether or not their post config hook has been
302 called before. Instead of a static variable (which is replaced when
303 the DSO is loaded a second time), use userdata in the process pool.
306 Changes with Apache 2.0a9
308 *) Win32 now requires perl to complete the final install step for users
309 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
310 and installs the conf, htdocs and htdocs/manual directories.
313 *) Make mod_include use a hash table to associate directive tags with
314 functions. This allows modules to implement their own SSI tags easily.
315 The idea is simple enough, a module can insert it's own tag and function
316 combination into a hash table provided by mod_include. While mod_include
317 parses an SSI file, when it encounters a tag in the file, it does a
318 hash lookup to find the function that implements that tag, and passes
319 all of the relevant data to the function. That function is then
320 responsible for processing the tag and handing the remaining data back
321 to mod_include for further processing.
322 [Paul J. Reder <rederpj@raleigh.ibm.com>]
324 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
325 fewer parameters: the local and remote socket addresses were removed
326 from the parameter list because all required information is available
327 via the APR socket. [Jeff Trawick]
329 *) Distribution directory structure reorganized to reflect a
330 normal source distribution with external install targets.
333 *) The MPMs that need multiple segments of shared memory now create
334 two apr_shmem_t variables, one for each shared memory allocation.
335 the problem is that we can't determine how much memory will be required
336 for shared memory allocations once we try to allocate more than one
337 variable. The MM code automatically aligns the shared memory allocations,
338 so we end up needing to pad the amount of shared memory we want based
339 on how many variables will be allocated out of the shared memory segment.
340 It is just easier to create a second apr_shmem_t variable, and two
344 *) Cleanup the export list a bit. This creates a single unified list of
345 functions exported by APR. The export list is generated at configure
346 time, and that list is then used to generate the exports.c file.
347 Because of the way the export list is generated, we only export those
348 functions that are valid on the platform we are building on.
351 *) Enable logging the cookie with mod_log_config
352 [Sander van Zoest <sander@covalent.net>]
354 *) Fix a segfault in mod_info when it reaches the end of the configuration.
357 *) Added lib/aputil/ as a placeholder for utility functions which are not
358 specific to the Apache HTTP Server (but do not make sense with APR).
359 The first utility is "apu_dbm": a set of functions to work with DBM
360 files. This first version can be compiled for SDBM or GDBM databases.
363 *) Complete re-write of mod_include. This makes mod_include a filter that
364 uses buckets directly. This has now served the FAQ correctly.
365 [Paul Reder <rederpj@raleigh.ibm.com>]
367 *) Allow modules to specify the first filter in a sub_request when
368 making the sub_request. This keeps modules from having to change the
369 output_filter immediately after creating the sub-request, and therefore
370 skip the sub_req_output_filter. [Ryan Bloom]
372 *) Update ab to accept URLs with IPv6 literal address strings (in the
373 format described in RFC 2732), and to build Host header fields in
374 the same format. This allows IPv6 literal address strings to be
375 used with ab. This support has been tested against Apache 1.3 with
376 the KAME patch, but Apache 2.0 does not yet work with this format
377 of the Host header field. [Jeff Trawick]
379 *) Accomodate an out-of-space condition in the piped logs and the
380 rotatelogs.c code, and no longer churn log processes for this
381 condition. [Victor J. Orlikowski]
383 *) Add support for partial writes with apr_sendfile() to core_output_filter.
386 Changes with Apache 2.0a8
388 *) Add a directive to mod_mime so that filters can be associated with
392 *) Get multi-views working again. We were setting the path_info
393 field incorrectly if we couldn't find the specified file.
396 *) Fix 304 processing. The core should never try to send the headers
397 down the filter stack. Always, just setup the table in the request
398 record, and let the header filter convert it to data that is ready
402 *) More fixes for the proxy. There are still bugs in the proxy code,
403 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
407 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
410 *) APR: Add new apr_getopt_long function to handle long options.
411 [B. W. Fitzpatrick <fitz@red-bean.com>]
413 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
414 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
415 hostname resolution/address string parsing and building
416 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
417 of one of the apr_sockaddr_t structures for a socket. Change
418 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
420 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
421 I have proxied pages with it, cleanup will commence soon.
424 *) Make the proxy work with filters. This isn't perfect, because we
425 aren't dealing with the headers properly. [Ryan Bloom]
427 *) Do not send a content-length iff the C-L is 0 and this is a head
428 request. [Ryan Bloom]
430 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
431 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
433 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
435 *) Get the default_handler to stop trying to deal with HEAD requests.
436 The idea is to let the content-length filter compute the C-L before
437 we try to send the data. If we can get the C-L correctly, then we
438 should send it in the HEAD response.
441 *) The Header filter can now determine if a body should be sent based
442 on r->header_only. The general idea of this is that if we delay
443 deciding to send the body, then we might be able to compute the
444 content-length correctly, which will help caching proxies to cache
445 our data better. Any handler that doesn't want to try to compute
446 the content-length can just send an EOS bucket without data and
447 everything will just work.
450 *) Add the referer to the error log if one is available.
451 [Markus Gyger <mgyger@itr.ch>]
453 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
454 change, the root of the configuration tree has been exposed to modules
456 [Ryan Morgan <rmorgan@covalent.net>]
458 *) Get the core_output_filter to use the bucket interface directly.
459 This keeps us from calling the content-length filter multiple times
460 for a simple static request.
463 *) We are sending the content-type correctly now.
464 [Ryan Bloom and Will Rowe]
466 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
467 a bogus bytes-sent value when the only thing being sent was trailers
468 and writev() returned an error (or EAGAIN). [Jeff Trawick]
470 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
471 hints file to determine which platforms define
472 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
475 *) APR: add apr_get_home_directory() [Jeff Trawick]
477 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
479 *) Not all platforms have INADDR_NONE defined by default. Apache
480 used to make this check and define INADDR_NONE if appropriate,
481 but APR needs the check too, and I suspect other applications will
482 as well. APR now defines APR_INADDR_NONE, which is always a valid
483 value on all platforms.
484 [Branko Èibej <brane@xbc.nu>]
486 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
487 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
489 *) Relax the syntax checking of Host: headers in order to support
490 iDNS. PR#6635 [Tony Finch]
492 *) When reading from file buckets we convert to an MMAP if it makes
493 sense. This also simplifies the default handler because the
494 default handler no longer needs to try to create MMAPs.
497 *) BUFF has been removed from the main server. The BUFF code will remain
498 in the code until it has been purged from the proxy module as well.
501 *) Byteranges have been completely re-written to be a filter. This
502 has been tested, and I believe it is working correctly, but it could
503 doesn't work for the Adobe Acrobat plug-in. The output almost matches
504 the output from 1.3, the only difference being that 1.3 includes
505 a content-length in the response, and this does not.
508 *) APR read/write functions and bucket read functions now operate
509 on unsigned integers, instead of signed ones. It doesn't make
510 any sense to use signed ints, because we return the error codes,
511 so if we have an error we should report 0 bytes read or written.
514 *) Always compute the content length, whether it is sent or not.
515 The reason for this, is that it allows us to correctly report
516 the bytes_sent when logging the request. This also simplifies
517 content-length filter a bit, and fixes the actual byte-reporing
518 code in mod_log_config.c
521 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
522 it says, because it was only used by EOS and FLUSH buckets. Since
523 neither of those are required at the end of a brigade, this was
524 really signifying FLUSH_THE_DATA, but that can be determined better
525 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
526 buckets now return a length of 0, which is actually the amount of data
527 read, so they make more sense.
530 *) Allow the core_output_filter to save some data past the end of a
531 request. If we get an EOS bucket, we only send the data if it
532 makes sense to send it. This allows us to pipeline request
533 responses. As a part of this, we also need to allocate mmap
534 buckets out of the connection pool, not the request pool. This
535 allows the mmap to outlive the request.
538 *) Make blocking and non-blocking bucket reads work correctly for
539 sockets and pipes. These are the only bucket types that should
540 have non-blocking reads, because the other bucket types should
541 ALWAYS be able to return something immediately.
544 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
545 server, but use Ctrl+Break to initiate a graceful restart
546 instead of duplicating behavior. [John Sterling]
548 *) Patch mod_autoindex to set the Last-Modified header based on
549 the directory's mtime, and add the ETag header. [William Rowe]
551 *) Merge the 1.3 patch to add support for logging query string in
552 such a way that "%m %U%q %H" is the same as "%r".
555 *) Port three log methods from mod_log_config 1.3 to 2.0:
556 CLF compliant '-' byte count, method and protocol.
559 *) Add a new LogFormat directive, %c, that will log connection
560 status at the end of the response as follows:
561 'X' - connection aborted before the response completed.
562 '+' - connection may be kept-alive by the server.
563 '-' - connection will be closed by the server.
566 *) Expand APR for WinNT to fully accept and return utf-8 encoded
567 Unicode file names and paths for Win32, and tag the Content-Type
568 from mod_autoindex to reflect that charset if the the feature
569 macro APR_HAS_UNICODE_FS is true. [William Rowe]
571 *) Compute the content length (and add appropriate header field) for
572 the response when no content length is available and we can't use
573 chunked encoding. [Jeff Trawick]
575 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
576 so that content input filters get dechunked data when using
577 the default handler. Also removed REQUEST_CHUNKED_PASS.
580 *) Add mod_ext_filter as an experimental module. This module allows
581 the administrator to use external programs as filters. Currently,
582 only filtering of output is supported. [Jeff Trawick]
584 *) Most Apache functions work on EBCDIC machines again, as protocol
585 data is now translated (again). [Jeff Trawick]
587 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
588 the EBCDIC support. They are noops on ASCII machines, so this
589 type of translation doesn't have to be surrounded by #ifdef
590 CHARSET_EBCDIC. [Jeff Trawick]
592 *) Fix mod_include. tag commands work again, and the server will
593 send the FAQ again. This also allows mod_include to set aside
594 buckets that include partial buckets.
595 [Ryan Bloom and David Reid]
597 *) Add suexec support back. [Manoj Kasichainula]
599 *) Lingering close now uses the socket directly instead of using
600 BUFF. This has been tested, but since all we can tell is that it
601 doesn't fail, this needs to be really hacked on.
604 *) Allow filters to modify headers and have those headers be sent to
605 the client. The idea is that we have an http_header filter that
606 actually sends the headers to the network. This removes the need
607 for the BUFF to send headers.
610 *) Charset translation: mod_charset_lite handles translation of
611 request bodies. Get rid of the xlate version of ap_md5_digest()
612 since we don't compute digests of filtered (e.g., translated)
613 response bodies this way anymore. (Note that we don't do it at
614 all at the present; somebody needs to write a filter to do so.)
617 *) Input filters and ap_get_brigade() now have a input mode parameter
618 (blocking, non-blocking, peek) instead of a length parameter.
621 *) Update the mime.types file to the registered media types as
622 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
625 *) Namespace protect some macros declared in ap_config.h
628 *) Support HTTP header line folding with input filtering.
631 *) Mod_include works again. This should still be re-written, but at
632 least now we can serve an SHTML page again.
635 *) Begin to remove BUFF from the core. Currently, we keep a pointer
636 to both the BUFF and the socket in the conn_rec. Functions that
637 want to use the BUFF can, functions that want to use the socket,
638 can. They point to the same place.
641 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
642 [Tomas "Ögren" <stric@ing.umu.se>]
644 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
645 associated pool goes away. (APR pipes on OS/2 were already had this
646 logic.) This resolvs a fatal file descriptor leak with CGIs.
649 *) The final line of the config file was not being read if there was
650 no \n at the end of it. This was caused by apr_fgets returning
651 APR_EOF even though we had read valid data. This is solved by
652 making cfg_getline check the buff that was returned from apr_fgets.
653 If apr_fgets return APR_EOF, but there was data in the buf, then we
654 return the buf, otherwise we return NULL.
657 *) Piped logs work again in the 2.0 series.
660 *) Restore functionality broken by the mod_rewrite security fix:
661 rewrite map lookup keys and default values are now expanded
662 so that the lookup can depend on the requested URI etc.
663 PR #6671 [Tony Finch]
665 *) Tighten up the syntax checking of Host: headers to fix a
666 security bug in some mass virtual hosting configurations
667 that can allow a remote attacker to retrieve some files
668 on the system that should be inaccessible. [Tony Finch]
670 *) Add a pool bucket type. This bucket is used for data allocated out
671 of a pool. If the pool is cleaned before the bucket is destroyed, then
672 the data is converted to a heap bucket, allowing it to survive the
676 *) Add a flush bucket. This allows modules to signal that the filters
677 should all flush whatever data they currently have. There is no way
678 to actually force them to do this, so if a filter ignores this bucket,
679 that's life, but at least we can try with this.
682 *) Add an output filter for sub-requests. This filter just strips the
683 EOS bucket so that we don't confuse the main request's core output
684 filter by sending multiple EOS buckets. This change also makes sub
685 requests start to send EOS buckets when they are finished.
688 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
689 makes ap_bucket_destroy a return void, which is okay because it
690 used to always return APR_SUCCESS, and nobody ever checked its
692 [Cliff Woolley <cliffwoolley@yahoo.com>]
694 *) Remove the index into the bucket-type table from the buckets
695 structure. This has now been replaced with a pointer to the
696 bucket_type. Also add some macros to test the bucket-type.
699 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
700 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
701 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
702 All _VAR_ flavors changes to _DATA to be absolutely clear.
705 *) Add support for /, //, //servername and //server/sharename
706 parsing of <Directory> blocks under Win32 and OS2.
707 [Tim Costello, William Rowe, Brian Harvard]
709 *) Remove the function pointers from the ap_bucket type. They have been
710 replaced with a global table. Modules are allowed to register bucket
711 types and use then use those buckets.
714 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
715 once we finish writing the request body to the cgi child process;
716 otherwise, the client doesn't hit EOF on stdin. Small request bodies
717 worked without this change (for reasons I don't understand), but large
718 ones didn't. [Jeff Trawick]
720 *) Remove file bucket specific information from the ap_bucket type.
721 This has been moved to a file_bucket specific type that hangs off
722 the data pointer in the ap_bucket type.
725 *) Input filtering now has a third argument. This is the amount of data
726 to read from lower filters. This argument can be -1, 0, or a positive
727 number. -1 means give me all the data you have, I'll deal with it and
728 let you know if I need more. 0 means give me one line and one line
729 only. A positive number means I want no more than this much data.
731 Currently, only 0 and a positive number are implemented. This allows
732 us to remove the remaining field from the conn_rec structure, which
736 *) Big cleanup of the input filtering. The goal is that http_filter
737 understands two conditions, headers and body. It knows where it is
738 based on c->remaining. If c->remaining is 0, then we are in headers,
739 and http_filter returns a line at a time. If it is not 0, then we are
740 in body, and http_filter returns raw data, but only up to c->remaining
741 bytes. It can return less, but never more.
742 [Greg Ames, Ryan Bloom, Jeff Trawick]
744 *) mod_cgi: Write all of the request body to the child, not just what
745 the kernel would accept on the first write. [Jeff Trawick]
747 *) Back out the change that moved the brigade from the core_output_filters
748 ctx to the conn_rec. Since all requests over a given connection
749 go through the same core_output_filter, the ctx pointer has the
753 *) Fix another bug in the send_the_file() read/write loop. A partial
754 send by apr_send would cause unsent data in the read buffer to
755 get clobbered. Complete making send_the_file handle partial
756 writes to the network.
759 *) Fix a couple of type fixes to allow compilation on AIX again
760 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
762 *) Fix bug in send_the_file() which causes offset to be ignored
763 if there are no headers to send.
766 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
767 filter. Useful for supporting Windows 9* with a binary
768 compiled on Windows NT.
771 Changes with Apache 2.0a7
773 *) Reimplement core_output_filter to buffer/save bucket brigades
774 across multiple calls to the core_filter. The brigade will be
775 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
776 thresholds are hit or the EOS bucket is received.
779 *) Create experimental filter (buffer_filter) that coalesces bytes
780 into one large buffer before invoking the next filter in the
781 chain. This filter is particularly useful with the current
782 implementation of mod_autoindex when it inserted above the
783 chunk_filter. mod_autoindex generates a lot of brigades that
784 containing buckets holding just a few bytes each. The
785 buffer_filter coalesces these buckets into a single large bucket.
788 *) Add apr_sendfile() support into the core_output_filter.
791 *) Add apr_sendv() support into the core_output_filter.
794 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
795 [Mike Abbott <mja@sgi.com>]
797 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
798 make much sense, because Apache uses buckets instead of BUFFs now.
801 *) send_the_file now falls back to a read/write loop on platforms that
802 do not have sendfile.
803 [Ryan Bloom and Brian Havard]
805 *) Install apachectl correctly, and substitute the proper values so
806 that it works again. [Ryan Bloom]
808 *) Better(??) handle platforms that lack sendfile().
811 *) APR now has UUID generation/formatting/parsing support.
814 *) Begin the http_filter. This is an input filter that understands
815 the absolute basic amount required to parse an HTTP Request. The
816 goal is to be able to split headers from request body before passing
817 the data back to the other filters.
820 *) Bring forward from 1.3.13 the config directory implementation
823 *) install apxs if it is created
826 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
827 conversions. [William Rowe]
829 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
830 ap_add_output_filter(). [Jeff Trawick]
832 *) Multiple build and configuration fixes
835 -add datadir and localstatedir substitutions
837 -fix logfilename misspelling
838 -fix evaluation of installation dir variables and
839 -replace $foobar by $(foobar) to be usefull in the makefile
843 -add rules for cross-compiling in rules.mk. Okay, rule to check for
844 $CC_FOR_BUILD is still missing
845 -use CHECK_TOOL instead of CHECK_PROG for ranlib
846 -add missing "AR=@AR@" to severaly Makefile.in's
847 -cache result for "struct rlimit"
848 -compile all helper programs with native and cross compiler
849 and use the native version to generate header file
850 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
852 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
854 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
856 *) Fix a bug where a client which only sends \n to delimit header
857 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
858 message. Start working on ebcdic co-existance with input
860 [William Rowe, Greg Ames]
862 *) If mod_so is enabled in the server always create libexec, even
863 if there are no modules installed in this directory. This is a
864 requirement for APXS to work correctly.
867 *) Connection oriented output filters are now stored in the
868 conn_rec instead of the request_rec. This allows us to add the
869 output filter in the pre-connection phase instead of the
870 post_read_request phase, which keeps us from trying to write an
871 error page before we have a filter to write to the network.
872 [Ryan Bloom, Jeff Trawick, and Greg Ames]
874 *) Cleaning up an mmap bucket no longer deletes the mmap. An
875 mmap can be used across multiple buckets (default_handler with
876 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
877 the mmap itself can't be associated with the bucket.
880 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
883 *) Radical surgery to improve mod_isapi support under Win32.
884 Includes a number of newer ServerSupportFunction calls, support
885 for ReadClient (in order to retrieve POSTs greater than 48KB),
886 and general bug fixes to more reliably load ISAPI .dll's and
887 prevent leaking handle resources. Note: There are still
888 discrepancies between IIS's and Apache's ServerVariables, and
889 async calls are still not supported. Additional warnings are
890 logged to facilitate debugging of unsupported ISAPI calls.
893 *) Add input filtering to Apache. The basic idea for the input
894 filters is the same as the ideas for output filters. The biggest
895 difference is that instead of calling ap_pass_brigade, ap_get_brigade
896 should be called, and the order of execution for the filter itself is
897 different. When writing an output filter, a brigade is passed in,
898 and filters operate directly on that brigade, when done, they call
899 ap_pass_brigade. Input filters are the exact opposite. Because input
900 is not a push operation, filters first call ap_get_brigade. When this
901 function returns, the input filter will be left with a valid brigade.
902 The input filter should then operate on the brigade, and return.
905 *) Fix building on BSD/OS using its native make. The build system
906 falls back to the BSD .include directive on that host platform.
909 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
910 SHA1 and plaintext password encodings. Make feature tests a
911 bit more flexible. [William Rowe]
913 *) Charset translation: mod_charset_lite handles output content
914 translation in a filter. mod_charset_lite no longer ignores
915 subrequests. A bunch of cruft related to BUFF's support for
916 translating request and response bodies was removed.
919 *) Move the addition of the CORE filter to the post_read_request
920 hook in http_core.c. This removes the need to add the filter in
921 multiple places and allows for an SSL module to be added much
922 simpler. [Ryan Bloom]
924 *) Fix a security problem that affects certain configurations of
925 mod_rewrite. If the result of a RewriteRule is a filename that
926 contains expansion specifiers, especially regexp backreferences
927 $0..$9 and %0..%9, then it may be possible for an attacker to
928 access any file on the web server. [Tony Finch]
930 *) Fix a bug where errors that are detected during early request parsing
931 don't produce visible HTTP error messages at the browser, because
932 the core_filter wasn't present. [Greg Ames]
934 *) Provide apr_socklen_t as a portability aid.
935 [Victor J. Orlikowski]
937 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
938 as well as a comment arg to the add, adduser and update cmds.
939 update allows the user to clear or preserve pw/groups/comment.
940 Fixed a bug in dbmmanage that prevented the check option from
941 parsing a password followed by :group... text. Corrected the
942 seed calcualation for Win32 systems, and added -lsdbm support.
945 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
948 *) Avoid a segfault when parsing .htaccess files. An
949 uninitialized tree pointer was passed to ap_build_config().
952 *) Change the way that inet_addr & inet_network are checked for
953 in APR's configure process to allow BeOS BONE to correctly
954 find them. With this change BeOS BONE now builds from source
955 with no problems. [David Reid]
957 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
958 the end of the parameters to execve() was stored in the wrong
959 location, overlaying the storage beyond the newargs[] array and
960 also passing uninitialized storage to execve(), which would
961 sometimes fail with EFAULT. [Jeff Trawick]
963 *) Fix a bug parsing configuration file containers. With a sequence
964 like this in the config file
966 <IfModule mod_kilroy.c>
969 <IfModule mod_lovejoy.c>
974 the second container would be terminated at the blank line due to
975 sediment in the buffer from reading the prior </IfModule> and an
976 error message would be generated for the real </IfModule> for the
977 second container. Also due to this problem, any two characters
978 could be used for "</" in the close of a container.
981 *) ap_add_filter prototype changed to remove the ctx pointer. The
982 pointer still remains in the filter structure, but it can not be
983 a part of the ap_add_filter prototype. The reason is that when
984 the core uses AddFilter to add a filter to the stack it doesn't
985 know how to allocate the ctx pointer, or even how much memory should
986 be allocated. The filters will have to be responsible for allocating
987 the ctx memory when they need it.
990 *) Add an AddFilter directive. This directive takes a list of filters
991 that should be activated for the requested resource.
994 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
995 some other platforms). [Jeff Trawick]
997 *) Modify mod_include to be a filter. Currently, it has only been tested
998 on actual files, but it should work for CGI scripts too.
1001 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
1002 writes. apr_flush() for Unix: handle interrupted writes.
1005 *) NameVirtualHost can now take "*" as an argument instead of
1006 an IP address. This allows you to create a purely name-based
1007 virtual hosting server that does not have any IP addresses in
1008 the configuration file and which ignores the local address
1009 of any connections. PR #5595, PR #4455 [Tony Finch]
1011 *) Fix some compile warnings in mod_mmap_static.c
1012 [Mike Abbott <mja@sgi.com>]
1014 *) Fix chunking problem with CGI scripts. The general problem was that
1015 the CGI modules were adding an EOS bucket and then the core added an
1016 EOS bucket. The chunking filter finalizes the chunked response when it
1017 encounters an EOS bucket. Because two EOS buckets were sent, we
1018 finalized the response twice. The fix is to make sure we only send one
1019 EOS, by utilizing a flag in the request_rec.
1022 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
1023 and Win32. Previously, the first read from an apr_file_t set up via
1024 apr_put_os_file() would return a '\0'. [Jeff Trawick]
1026 *) Mod_cgid now creates a single element bucket brigade, with a pipe
1027 bucket, instead of using BUFF's and ap_r*.
1030 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
1031 [Mike Abbott <mja@sgi.com>]
1033 *) Remove ap_bopenf from buff code. This required modifying the file_cache
1034 code to use APR file's directly instead of going through BUFFs.
1037 *) Fix compile break on some platforms for mod_mime_magic.c
1038 [John K. Sterling <sterling@covalent.net>]
1040 *) Fix merging of AddDefaultCharset directive.
1041 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
1043 *) Minor revamp of the rlimit sections of code. We now test
1044 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
1045 is now "available" even if the platform doesn't support
1046 the rlimit family (it's just a noop though). [Jim Jagielski]
1048 *) Migrate the pre-selection of which MPM to use for specific
1049 platforms to hints.m4, which contains (or should contain)
1050 all platform specific "hints". [Jim Jagielski]
1052 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
1055 *) Add tables with non-string/binary values to APR.
1058 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
1061 *) Update PCRE to version 3.2. [Ryan Bloom]
1063 *) Change the way buckets' destroy functions are called so that
1064 they can be more directly used when changing the type of a
1065 bucket in place. [Tony Finch]
1067 *) Add generic support for reference-counting the resources used by
1068 buckets, and alter the HEAP and MMAP buckets to use it. Change
1069 the way buckets are initialised to support changing the type of
1070 buckets in place, and use it when setting aside TRANSIENT buckets.
1071 Change the implementation of TRANSIENT buckets so that it can be
1072 mostly shared with IMMORTAL buckets, which are now implemented.
1075 Changes with Apache 2.0a6
1077 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
1079 *) Add a chunking filter to Apache. This brings us one step closer
1080 to removing BUFF. [Ryan Bloom]
1082 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
1083 added to the stack is the last filter to be called. [Ryan Bloom]
1085 *) Apache 2.0 has been completely documented using Scandoc. The
1086 docs can be generated by running 'make docs'. [Ryan Bloom]
1088 *) Add filtered I/O to Apache. This is based on bucket brigades,
1089 Currently the buckets still use BUFF under the covers, but that
1090 should change quickly. The only currently written filter is the
1091 core filter which just calls ap_bwrite. [The Apache Group]
1093 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
1094 built with thread support. [Jeff Trawick]
1096 *) Abort configuration if --with-layout was specified and there's
1097 no layout definition file. [Ken Coar]
1099 *) Add support for '--with-port=n' option to configure. [Ken Coar]
1101 *) Add support for extension methods for the Allow response header
1102 field, and an API routine for accessing r->allowed and the
1103 list of extension methods in a unified manner. [Ken Coar]
1105 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
1106 [Rob Simonson <simo@us.ibm.com>]
1108 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
1109 APACHE_XLATE builds. [Jeff Trawick]
1111 *) A configuration file parsing problem was fixed. When the
1112 configuration file started with an IfModule/IfDefine container,
1113 only the last statement in the container would be retained.
1116 Changes with Apache 2.0a5
1118 *) Perchild is serving pages after passing them to different child
1119 processes. There are still a lot of bugs, but this does work. I
1120 have made requests against the same installation of Apache, and had
1121 different servers use different user IDs to serve the responses.
1122 This change moves to using socketpair instead of an AF_UNIX socket.
1125 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
1126 It can't seem to pass between child processes yet, but I think we
1127 are closer now than before. This moves us back to using Unix
1128 Domain Sockets. [Ryan Bloom]
1130 *) libapr functions and types renamed with apr_ prefix.
1131 #include "apr_compat.h" for 1.3.x backwards compat
1134 *) Fix problems with APR sockaddr handling on Win32. It didn't always
1135 return the right information on the local socket address.
1136 [Gregory Nicholls <gnicholls@level8.com>]
1138 *) ap_recv() on Win32: Set bytes-read to 0 on error.
1139 [Gregory Nicholls <gnicholls@level8.com>]
1141 *) Add an option to not detach from the controlling terminal without
1142 going into single process mode. This allows for much easier
1143 debugging of the process startup code. [Ryan Bloom]
1145 *) ab: don't use perror() to report the failure of an APR function.
1148 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
1149 scoreboard on graceful restarts.
1152 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
1153 An invalid ap_proc_t was passed to ap_create_process().
1156 *) Allow modules to register filters. Those filters are still
1157 never called, but this is a step in the right direction.
1158 [Ryan Bloom and Greg Stein]
1160 *) Register the mod_cgid daemon process for cleanup so that it is
1161 killed at termination if it does not die when the parent gets
1162 SIGTERM. This change is to fix occasional problems where the
1163 process stays around. Bugs in similar logic in mod_rewrite and
1164 mod_include were also fixed. [Jeff Trawick]
1166 *) Fix a bug in the time handling. Basically, we were imploding a time
1167 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
1168 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
1169 uses those two fields to adjust the time value. Because of the HTTP
1170 spec, both of those values can be zero'ed out safely. This fixes
1171 the bug correctly. [Ryan Bloom]
1173 *) Fix a couple of place in the Windows code where the wrong error
1174 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
1176 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
1178 *) Added the APR_EOL_STR macro for platform dependent differences in
1179 logfiles and other raw text (such as all APR files). Fixes logfiles
1180 not terminated with cr/lf sequences in Win32. [William Rowe]
1182 *) Move all strings functions in APR to src/lib/apr/strings and create
1183 apr_strings.h for the prototypes. [Ryan Bloom]
1185 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
1186 to repeat the syscall until we stop getting EINTR. I noticed a
1187 related problem at termination (SIGTERM) on FreeBSD when using
1188 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
1189 implementation work properly with child init. Previously, ap_lock()
1190 was essentially a no-op because all children were using different
1191 locks and thus nobody ever blocked. [Jeff Trawick]
1193 *) The htdocs/ tree has been moved out of the CVS source tree into
1194 a separate area for easier development. This has NO EFFECT on
1195 end-users or Apache installations. [Ken Coar]
1197 *) Integrate the mod_dav module for WebDAV protocol handling. This
1198 adds the dav and dav_fs modules, the SDBM library, and additional
1199 XML handling utilities. [Greg Stein]
1201 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
1204 *) Update the lib/expat-lite/ library (bring forward changes from
1205 the Apache 1.3 repository). [Greg Stein]
1207 *) If sizeof(long long) == sizeof(long), then prefer long in APR
1208 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
1210 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
1211 machines where sendfile is detected, but nobody has written ap_sendfile.
1212 [Dave Hill <ddhill@zk3.dec.com>]
1214 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
1216 *) ab would start up more connections than needed, then quit when the
1217 desired number were finished. Also fixed a logic error involving
1218 ab keepalives. [Victor J. Orlikowski]
1220 *) WinNT: Implement non-blocking pipes with timeouts to communicate
1221 with CGIs. Apache 2.0a4 had non-blocking pipes but without
1222 timeouts (i.e, if a timeout was specified, the pipe reverted to
1223 a full blocking pipe). Now the behaviour is more in line with
1224 Unix non-blocking pipes.
1227 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
1228 cache open file handles along with accept socket reuse enables
1229 Apache 2.0 to serve non-keepalive requests for static files at
1230 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
1231 and Apache 2.0 will serve almost 1200 rps on my system).
1234 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
1235 supports two config directives, mmapfile (same behavious as
1236 mod_mmap_static) and cachefile. Use the cachefile directive
1237 to cache open file handles. This directive only works on systems
1238 that have implemented the ap_sendfile API. cachefile works today
1239 on Windows NT, but has not been tested on any flavors of Unix.
1242 *) Cleanup the configuration. With the last few changes the
1243 configuration process automatically:
1244 inherits information about how to build from APR. Allowing
1245 APR to inform Apache that it should or should not use -ldl
1247 Detects which mod_cgi should be used mod_cgi or mod_cgid,
1248 based on the threading model
1250 Apache calls APR's configure process before finishing it's
1251 configuration processing, allowing for more information flow
1256 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
1257 with non-zero argument makes the socket non-blocking. BeOS and
1258 OS/2 already worked this way. [Jeff Trawick]
1260 *) ap_close() now calls ap_flush() for buffered files, so write
1261 operations work a whole lot better on buffered files.
1264 *) Fix error messages issued from MPMs which explain where to change
1265 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
1268 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
1269 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
1270 now the way that the blocking state of a pipe is manipulated.
1271 ap_block_pipe() is gone. [Jeff Trawick]
1273 *) Correct the problem where the only local host name that the IP stack
1274 can discover are 'undotted' private names. If no fully qualified
1275 domain name can be identified, the default ServerName will be set to
1276 the machine's IP address string. A warning is always provided if the
1277 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
1279 *) Repair problems with config file processing which caused segfault
1280 at init when virtual hosts were defined and which caused ServerName to
1281 be ignored when there was no valid DNS setup. [Jeff Trawick]
1283 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
1285 *) Add ap_sendfile implementation for AIX
1286 [Victor J. Orlikowski]
1288 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
1289 apr_network_io.h, and apr_thread_proc.h.
1290 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
1292 *) Bring the allocation and pool debugging code back into a working
1293 state. This will need to be tested as so far it's only been used on
1296 *) Change configuration command setup to be properly typesafe when in
1297 maintainer mode. Note that this requires a compiler that can initialise
1298 unions. [Ben Laurie]
1300 *) Turn on buffering for config file reads. Part of this was to
1301 repair buffered I/O support in Unix and implement buffered
1302 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
1304 *) Win32: Fix problem where UTC offset was not being set correctly
1305 in the access log. Problem reported on news group by Jerry Baker.
1308 *) Fix segfault when reporting this type of syntax error:
1309 "</container> without matching <container> section", where
1310 container is VirtualHost or Directory or whatever.
1313 *) Prevent the source code for CGIs from being revealed when using
1314 mod_vhost_alias and the CGI directory is under the document root
1315 and a user makes a request like http://www.example.com//cgi-bin/cgi
1316 as reported in <news:960999105.344321@ernani.logica.co.uk>
1319 *) Add support for the new Beos NetwOrking Environment (BONE)
1322 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
1323 final input char is incomplete; ap_bwrite_xlate() now handles
1324 incomplete final input chars. [Jeff Trawick]
1326 *) Yet another update to saferead/halfduplex stuff -- need to ensure
1327 that a bhalfduplex call occurs before logging or else DNS and
1328 such can delay the last packet of the response. [Dean Gaudet]
1330 *) Some syscall reduction in APR on unix -- don't seek when setting
1331 up an mmap; and don't fcntl() more than once per socket.
1334 *) When mod_cgid is started as root, the cgi daemon now switches
1335 to the configured User/Group (like other httpd processes)
1336 instead of continuing as root. [Jeff Trawick]
1338 *) The prefork MPM now uses an APR lock for the accept() mutex.
1339 It has not been getting a lock at all recently. httpd -V now
1340 displays APR's selection of the lock mechanism instead of the
1341 symbols previously respected by prefork. [Jeff Trawick]
1343 *) Change the mmap() feature test to check only for existence.
1344 The previous check required features not used by Apache.
1347 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
1348 sometimes mangled. The len parm to accept() was not
1349 initialized, leading sometimes to an endless loop of failed
1350 accept() calls on OS/390 and anywhere else that failed the call
1351 if the len was negative. Use <sys/un.h> for struct sockaddr_un
1352 instead of declaring it ourselves to fix a compilation problem
1353 on Solaris. [Jeff Trawick]
1355 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
1357 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
1359 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
1361 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
1362 initialization if ALLOC_DEBUG is defined; no known symptom
1363 otherwise. [Jeff Trawick]
1365 *) Fix typo in configure script when checking for mod_so. bash
1366 doesn't seem to have a problem but /bin/sh on Solaris does.
1367 Symptom: "./configure: test: unknown operator =="
1370 *) Rebind the Win32 NT and 9x services control into the MPM.
1371 All console, WinNT SCM and Win9x pseudo-service control code is
1372 now wrapped within the WinNT MPM.
1375 *) Make a copy of getenv("PATH") before storing for later use. Some
1376 getenv() implementations use the same storage for successive calls.
1377 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
1379 *) Server Tokens work in 2.0 again. This also propogates the change
1380 to allow just the product name in the server string using
1384 Changes with Apache 2.0a4
1386 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
1387 won't need to call it. [Greg Ames, Jeff Trawick]
1389 *) Move pre_config hook call to between configuration read and config
1390 tree walk. This allows all modules to implement pre_config hooks
1391 and know that they will be called at an appropriate time.
1394 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
1397 *) Add pre-config hooks back to all modules.
1400 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
1401 ContentDigest enabled and we can't/don't mmap the file.
1404 *) We now report the correct line number for syntax errors in config
1405 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
1407 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
1408 related bugs, and changed shmem/locking to use apr API. Shared-mem
1409 is currently disabled, however, because of problems with graceful
1410 restarts. [Ronald Tschalär]
1412 *) Fix corruption of IFS variable in --with-module= handling.
1413 Depending on the user's shell or customization thereof, there
1414 would be errors generating ap_config_auto.h later in the configure
1415 procedure. [Jeff Trawick]
1417 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
1418 isn't used (as in 1.3), except that on Unix it is now logged via
1419 ap_log_rerror() instead of by the child having STDERR_FILENO refer
1420 to the error log. [Greg Ames, Jeff Trawick]
1422 *) Add '-D' argument processing for run time configuration defines.
1425 *) Organize http_main.c as independent code, such that no code or
1426 global data is exported from it. WIN32 will dynamically link it
1427 to the server core, so this will prevent mutual dependency.
1430 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
1431 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
1434 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
1435 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
1437 *) Add mod_charset_lite for configuring character set translation.
1440 *) Add '-n' option to htpasswd to make it print its user:pw record
1441 on stdout rather than having to frob a text file. [Ken Coar]
1443 *) Fix saferead. Basically, we flush the output buffer if a read on the
1447 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
1448 a conversion is single-byte only. [Jeff Trawick]
1450 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
1451 the BeOS 5.0 documentation says that shutdown doesn't work yet.
1454 *) Fix some minor errors where pid was being manipulated as an int
1455 instead of the portable pid_t. [Roy Fielding]
1457 *) Fix some error log prints that were printing the pointer to a
1458 structure rather than the pid within the structure.
1459 [Jeff Trawick, Roy Fielding]
1461 *) ab: Fix a command-line processing bug; track bad headers in
1462 err_response; support reading headers up to 2K.
1463 [Ask Bjoern Hansen <ask@valueclick.com>]
1465 *) Fix ap_resolve_env() so that it handles new function added in a prior
1466 alpha (see "Added the capability to do ${ENVVAR} constructs in the
1467 config file.") as well as the constructs used by mod_rewrite.
1468 [Paul Reder <rederpj@raleigh.ibm.com>]
1470 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
1472 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
1473 APR to perform translation, instead of accessing the hard-coded tables
1474 in 1.3's ebcdic.c. [Jeff Trawick]
1476 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
1479 *) Add the ability to hook into the config file reading phase. Basically
1480 if a directive is specified EXEC_ON_READ, then when that directive is
1481 read from the config file, the assocaited function is executed. This
1482 should only be used for those directives that must muck with HOW the
1483 server INTERPRETS the config. This should not be used for directives
1484 that re-order or replace items in the config tree. Those changes should
1485 be made in the pre-config step.
1488 *) Add mod_example to the build system.
1491 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
1492 byte character sets. [Jeff Trawick]
1494 *) Pick up various EBCDIC fixes from 1.3 (from Martin
1495 Kraemer and Oliver Reh originally according to the change log).
1498 *) Fix a couple of problems in RFC1413 support (controlled by the
1499 IdentityCheck directive). Apache did not build the request string
1500 properly and more importantly Apache would loop forever if the
1501 would-be ident server dropped the connection before sending a
1502 properly terminated response. [Jeff Trawick]
1504 *) apxs works in 2.0.
1507 *) Reliable piped logs work in 2.0.
1510 *) Introduce a hash table implementation into APR to be used for
1511 replacing tables and other random data structures in Apache.
1514 *) Add some more error reporting to htpasswd in the case of problems
1515 generating or accessing the temporary file. Also, pass in a
1516 buffer if the implementation knows how to use it (i.e., if L_tmpnam
1517 is defined). [Ken Coar]
1519 *) Configure creates config.nice now containing your configure
1520 options. Syntax: ./config.nice [--more-options]
1523 *) Fix various return code problems in APR on Win32. For most of
1524 these, APR was returning APR_EEXIST instead of GetLastError()/
1525 WSAGetLastError(). [Jeff Trawick]
1527 *) Make piped logs work again in version 2.0
1530 *) Add VPATH support to UNIX build system of Apache and APR.
1533 *) Fix ap_tokenize_to_argv to respect the const arguments that are
1537 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
1538 Patch submitted to author.
1541 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
1542 /sbin in PATH on FreeBSD (all submitted to rse previously)
1545 *) Fix building Pthread-based MPMs on OpenBSD
1546 [Sascha Schumann] PR#26
1548 *) Fix ap_readdir() problem on systems where d_name[] field in
1549 struct dirent is declared with only one byte. (This problem only
1550 affected multithreaded builds.) This caused a segfault during
1551 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
1552 least). [Jeff Trawick]
1554 *) Fix some make-portability problems on at least Tru64, Irix
1556 [Sascha Schumann] PR#18, PR#39
1558 *) Add ap_sigwait() to support old-style sigwait() on systems
1559 like OS/390 and UnixWare.
1562 *) Add POSIX-thread flags for more platforms.
1565 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
1566 (on Unix, at least) to handle resolver errors. Fix a bug in
1567 the definition of APR_ENOMEM so that ap_strerror() can spit
1568 out the correct error message for it.
1571 Changes with Apache 2.0a3
1573 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
1576 *) API: *HOOK* macros now have an AP_ prefix
1579 *) Win32: Eliminate redundant calls to initialize winsock.
1580 [Tim Costello <timcostello@ozemail.com.au>]
1582 *) Fix bugs initializing ungetchar for pipes.
1583 [Chia-liang Kao <clkao@CirX.ORG>]
1585 *) The ab program in the src/support directory is now portable using
1589 *) Support directory is being compiled when the server is built
1592 *) The configure option --with-program-name has been added to allow
1593 developers to rename the executable at configure time. This also
1594 changes the name of the config files to match the executable's name.
1597 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
1598 containing version numbers. [Martin Pool]
1600 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
1601 Unix; access_log and error_log now created with these perms; non-
1602 Unix is unaffected [Jeff Trawick]
1604 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
1605 Replaced more magic numbers with MD5_DIGESTSIZE.
1606 [William Rowe, Roy Fielding]
1608 *) Win32: Get mod_auth_digest compiling and added to the Windows
1609 build environment. Not tested and I'd be suprised if it
1610 actually works. [Bill Stoddard]
1612 *) Revamp the Win32 make environment. Makefiles have been removed and
1613 Apache.dsw created to bring together all the pieces. Create new file
1614 os/win32/BaseAddr.ref to define module base addresses (to prevent
1615 dll relocation at start-up).
1616 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
1618 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
1619 of the \015, \012, and \015\012 constants with macros.
1620 [Greg Ames <gregames@us.ibm.com>]
1622 *) Add ap_xlate_open() et al for translation of text between different
1623 character sets. The initial implementation requires iconv().
1626 *) More FAQs and answers from comp.infosystems.www.servers.unix.
1627 [Joshua Slive <slive@finance.commerce.ubc.ca>]
1629 *) CGI output is being timed out now.
1632 *) Fix the problem with dieing quietly. dupfile now takes a pool which
1633 is used by the new apr file. There is no reason to create a new file
1634 with the same lifetime as the original file.
1637 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
1638 module base addresses. This will help shooting seg faults
1639 in the field. [William Rowe <wrowe@lnd.com>]
1641 *) Update Apache on Windows documentation. Add new document
1642 describing how to compile Apache on Windows.
1643 [William Rowe <wrowe@lnd.com>]
1645 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
1646 microseconds instead of seconds. Some storage leaks and other
1647 minor bugs in related code were fixed. [Jeff Trawick]
1649 *) Win32: First cut at getting mod_isapi working under 2.0
1650 [William Rowe <wrowe@lnd.com>]
1652 *) First stab at getting mod_auth_digest working under 2.0
1653 quick change summary:
1654 - moved the random byte generation (ap_generate_random_bytes) into APR
1655 - now uses ap_time_t
1656 - compiles and runs on linux
1658 [Brian Martin <bmartin@penguincomputing.com>]
1660 *) Win32: Move the space stripping of physical service names
1661 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
1662 unresolved symbol. Add dependency checking to the
1663 CreateService call to ensure TCPIP and AFP (winsock) is started
1665 [William Rowe <wrowe@lnd.com>]
1667 *) Win32: Add code to perform latebinding on functions that may
1668 not exist on all levels of Windows where Apache runs. This
1669 is needed to allow Apache to start-up on Win95/98. All calls
1670 to non portable functions should be protected with
1671 ap_oslevel checks to prevent runtime segfaults.
1672 [William Rowe <wrowe@lnd.com>]
1674 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
1676 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
1678 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
1679 This addresses PR 1623. Still need to address timing out runaway
1680 CGI scripts. [Bill Stoddard]
1682 *) Win32: Make ap_stat Windows 95/98 friendly
1683 [William Rowe <wrowe@lnd.com>]
1685 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
1686 always fail. Need to initialise the dwOSVersionInfoSize member of the
1687 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
1690 The patch also enhances ap_get_oslevel (and the associated enum) to
1691 handle selected service packs for NT4, and adds recognition for
1692 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
1693 we can use ReadFileScatter and WriteFileGather in readwrite.c.
1694 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
1696 *) Get mod_rewrite building and running, and mod_status building for Win NT
1697 [Allan Edwards <ake@raleigh.ibm.com>]
1699 *) Patch to port mod_auth_db to the 2.0 api and also to support
1700 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
1701 2.7.7. It should work with version 1 as well but I haven't tested it.
1702 [Brian Martin <bmartin@penguincomputing.com>]
1704 *) Get APR DSO code working under Windows. Includes cross platform
1706 [Tim.Costello@BTFinancialgroup.com]
1708 *) Fix some of the Windows APR time functions.
1711 *) FAQ changes related to tidying up historical documents on the web site.
1712 [Joshua Slive <slive@finance.commerce.ubc.ca>]
1714 *) Move Windows DSO code into APR.
1717 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
1718 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
1719 at build time. At this point, the server will not compile on Windows because
1720 of the recent DSO commits. Fixing those next.
1721 [Bill Rowe & Bill Stoddard]
1723 *) Added error checking for file I/O APR routines.
1724 [Jon Travis <jtravis@covalent.net>]
1726 *) APR: Don't use the values of resolver error codes for the
1727 corresponding APR error codes. On Unix and Win32, return the
1728 proper APR error code after a resolver error. [Jeff Trawick]
1730 Changes with Apache 2.0a2
1732 *) Renamed the executable back to httpd on all platforms other
1736 *) Allow BeOS to survive restarts, log properly and a few
1737 small things it had problems with due to the way it setup
1738 users and groups. [David Reid]
1740 *) Get mod_rewrite working with APR locks
1741 [Paul Reder <rederpj@raleigh.ibm.com>]
1743 *) Actually remove the sempahore when the lock cleanup routine
1744 is called on BeOS. [David Reid]
1746 *) Clear hook registrations between reads of the config file.
1747 When DSOs are unloaded and re-loaded the old hook pointers may
1748 no longer be valid. This fix eliminates potential segfaults.
1749 [Allan Edwards <ake@raleigh.ibm.com>]
1751 *) Fix a problem with Sigfunc not being defined or bypassed
1752 if sigaction() wasn't found. [Jim Jagielski]
1754 *) Fix the locking mechanism on BSD variants. They now use fcntl
1755 locks. This allows the server to start and serve pages.
1758 *) First cut at getting the Win32 installer to work
1759 [William Rowe <wrowe@lnd.com>]
1761 *) Get htpasswd compiling under Windows
1762 [William Rowe <wrowe@lnd.com>]
1764 *) Change the log message for a bind() failure to show the
1765 interface and port number. [Jeff Trawick]
1767 *) Import the documentation from 1.3.12 and bring parts of it
1768 up-to-date with respect to the changes that have occurred
1772 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
1773 now logged correctly on BeOS.
1776 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
1777 Makefile.win includes the same user interface as the old
1779 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
1781 *) Win32 exec now uses COMSPEC environment string for command
1782 shell path resolution.
1783 [William Rowe <wrowe@lnd.com>] PR#3715
1785 *) Win32: ap_connect() was not returning correct error condition
1787 [Allen Prescott <allen@clanprescott.com>]
1789 *) Win32: ap_open() was broken on Win9x because an NT-specific
1790 flag was passed to CreateFile. ap_puts() added an unnecessary
1792 [Jeff Trawick <trawick@us.ibm.com>]
1794 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
1795 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
1796 confusing ee/et name and made all extensions language/dialect
1797 rather than country reflecting. Changed example files to
1798 explicit reflect the ISO charset and added a few common
1799 ones to the example config [dirkx]
1801 *) Extend external module capability. To use this, you call
1802 configure with --with-module=path/to/mod1,path/to/mod2,etc.
1805 *) Backported the various "default charset" fixes from 1.3.12,
1806 including the AddDefaultCharset directive. [Jim Jagielski]
1808 *) Added the capability to do ${ENVVAR} constructs in the
1809 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
1810 it does this on a line by line basis; i.e. if the envvar
1811 expands to something with spaces you have to protect it
1812 by adding quotes around it (Unless of course you expect it
1813 to contains more than one argument. Alternatively you
1814 can compile it on a per token basis; which is what people
1815 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
1816 hampers fancier hacks.
1817 [Dirk-Willem van Gulik]
1819 *) Changed the 'ErrorDocument' syntax in that it NO longer
1820 supports the asymetric
1822 ErrorDocument 301 "Some message
1824 Note the opening " quote, without a closing quote. It now
1825 has either the following syntaxes
1827 ErrorDocument XXX /local/uri
1828 ErrorDocument XXX http://valid/url
1829 ErrorDocument XXX "Some Message"
1831 The recognition heuristic is: if it has a space it
1832 is a message. If it has no spaces and starts with a /
1833 or is a valid URL then treat it that way. Otherwise it
1834 is assumed to be a message.
1836 This breaks backward compatibility but makes live a hell
1837 of a lot easier for GUI's and config file parsers.
1838 [Dirk-Willem van Gulik]
1840 *) Changed 'CacheNegotiatedDocs' from its present/not-present
1841 syntax into a 'on' or 'off' syntax. As it currently is the
1842 only non nesting token which uses NO_ARGS and thus is an
1843 absolute pain for any config interface automation. This
1844 breaks backward compatibility. [Dirk-Willem van Gulik]
1846 *) Add ability to add external modules to the build process. This is
1847 done with --with-module=/path/to/module. Modules can only be added
1848 as static modules at this point.
1851 Changes with Apache 2.0a1
1853 *) Fix FreeBSD 3.3 core dump.
1854 Basically, ap_initialize() needs to get called before
1855 create_process(), since create_process() passes op_on structure
1856 to semop() to get a lock, but op_on isn't initialized until
1857 ap_initialize() calls setup_lock(). Here is a slight
1858 rearrangement to main() which calls ap_initialize() earlier...
1859 [Jeff Trawick <trawick@us.ibm.com>]
1861 *) Enable Apache to use sendfile/TransmitFile API
1862 [Bill Stoddard, David Reid, Paul Reder]
1864 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
1868 *) Make file I/O and network I/O writev/sendv APIs consistent.
1869 Eliminate use of ap_iovec_t and use Posix struct iovec.
1870 Use seperate variable on ap_writev to set the number of iovecs
1871 passed in and number of bytes written.
1874 *) Adapt file iol to use APR functions. Replaced ap_open_file()
1875 with ap_create_file_iol(). ap_create_file_iol() requires that
1876 the file be opened prior to the call using ap_open().
1879 *) Port mod_include and mod_cgi to 2.0
1880 [Paul Reder, Bill Stoddard]
1882 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
1883 bytes_read/bytes_written is always valid (never -1). Plus
1884 some fixes to buff.c to correct problems introduced by the
1885 errno => ap_status_t changes a while back. Plus a fix to
1886 chunked encoding introduced right at the beginning of 2.0.
1889 *) Revamped UNIX build system to use autoconf and libtool.
1890 [Manoj Kasichainula, Sascha Schumann]
1892 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
1894 *) More rigorous checking of Host: headers to fix security problems
1895 with mass name-based virtual hosting (whether using mod_rewrite
1896 or mod_vhost_alias).
1897 [Ben Hyde, Tony Finch]
1899 *) Add back support for UseCanonicalName in <Directory> containers.
1900 [Manoj Kasichainula]
1902 *) Added APLOG_STARTUP log type. This allows us to write an error
1903 message without any of the date and time information. As a part
1904 of this change, I also removed all of the calls to fprintf(stderr
1905 and replaced them with calls to ap_log_error using APLOG_STARTUP
1906 writing to stderr is no longer portable, because we don't direct
1907 stderr to the error log on all platforms.
1910 *) Convert error logging functions to take errno as an argument.
1911 This makes our error logs more portable, because some Windows API's
1912 don't set errno. This change allows us to still output a valid
1913 message on all of our platforms.
1916 *) mod_mime_magic runs in 2.0-dev now.
1917 [Paul Reder <rederpj@raleigh.ibm.com>]
1919 *) sendfile has been added to APR.
1920 [John Zedlewski <zedlwski@Princeton.EDU>]
1922 *) buff.c has been converted to no longer use errno.
1923 [Manoj Kasichainula]
1925 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
1926 interface adaption to APR functions did it. [Martin Kraemer]
1928 *) Support DSOs properly on 32-bit HP-UX 11.0
1929 [Dilip Khandekar <dilip@cup.hp.com>]
1931 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
1932 [Ralf S. Engelschall]
1934 *) Cleaned APR build environment integration and bootstrap APR
1935 automatically for developers from src/Configure.
1936 [Ralf S. Engelschall]
1938 *) Fixed building of src/support/htpasswd.c
1939 [Ralf S. Engelschall]
1941 *) When generating the Location: header, mod_speling forgot
1942 to escape the spelling-fixed uri. (Forw-Port from 1.3)
1945 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
1947 *) Change all pools to APR contexts. This is the first step to
1948 incorporating APR into Apache. [Ryan Bloom]
1950 *) Move "handler not found" warning message to below the check
1951 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
1952 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
1954 *) Support line-continuation feature in config.option file and
1955 allow the loading of multiple option sections at once via
1956 ``--with-option=<section1>,<section2>,...''
1957 [Ralf S. Engelschall]
1959 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
1961 Changes with Apache MPM
1963 *) Use asynchronous AcceptEx() and a completion port to accept and
1964 dispatch connections to threads in Windows NT/2000.
1967 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
1970 *) Implement the APACI --with-option facility
1971 (per default used the config.option file).
1972 [Ralf S. Engelschall]
1974 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
1976 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
1977 Replace pre_connection module call with a register_hook call and
1978 implement pre_connection as a hook. The intent is that these hooks will
1979 be extended to allow Apache to be multi-protocol, and also to allow the
1980 calling order to be specified on a per-hook/per-module basis.
1983 *) Implement mpm_* methods as "modules". Each method gets its own
1984 subdir in src/modules (eg: src/modules/prefork). Selection
1985 of method uses Rule MPM_METHOD. [Jim Jagielski]
1987 *) Port the hybrid server from the apache-apr repository as
1988 mpm_mpmt_pthread. [Manoj Kasichainula]
1990 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
1991 amongst the unix MPMs.
1993 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
1994 signal handling for the new world order. [Dean Gaudet]
1996 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
1997 of alloc.c for now. [Dean Gaudet]
1999 *) Handle partial large writes correctly. [Ben Laurie]
2001 *) Eliminate conn_rec's pointer to server. All it knows is the base server
2002 based on IP/port. [Ben Laurie]
2004 *) Port a bunch of modules to the new module structure.
2005 ["Michael H. Voase" <mvoase@midcoast.com.au>]
2007 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
2009 *) Basic restructuring to introduce the MPM concept; includes various
2010 changes to the module API... better described by
2011 docs/initial_blurb.txt. [Dean Gaudet]
2013 Changes with Apache pthreads
2015 *) New buff option added: BO_TIMEOUT. It describes the timeout for
2016 buff operations (generally over a network).
2017 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
2019 *) Created http_accept abstraction. Added 4 new functions (not exported):
2020 init_accept(), begin_accepting_requests(), get_request(),
2021 stop_accepting_requests() [Bill Stoddard]
2023 *) Fix to ap_rprintf call that allows mod_info to work properly.
2024 [James Morris <jmorris@intercode.com.au>]
2026 *) user and ap_auth_type fields were moved from connection_rec to
2027 request_rec. [Ryan Bloom]
2029 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
2030 needed in a threaded server.
2032 *) Initial pthread implementation from from Dean's apache-nspr code.
2033 [Bill Stoddard, Ryan Bloom]
2036 Changes with Apache 1.3.9
2038 *) Remove bogus error message when a redirect doesn't set Location.
2039 Instead, use an empty string to avoid coredump if the error message
2040 was supposed to include a location. [Roy Fielding]
2042 *) Don't allow configure to include mod_auth_digest unless it is
2043 explicitly requested, even if the user asked for all modules.
2046 *) Translate module names to dll names for OS/2 so that they are no more
2047 than 8 characters long and have an extension of "dll" instead of "so".
2050 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
2051 Fix test-compile check to check for randbyte instead of trand32.
2052 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
2053 and tweak to make Amaya happier. [Ronald Tschalär]
2055 *) Ensure that the installed expat include files are world readable,
2056 just like the other header files. [Martin Kraemer]
2058 *) Fixed generated AddModule adjustments in APACI's `configure' script
2059 in order to allow (new) modules like mod_vhost_alias to be handled
2060 correctly (which was touched by the adjustments for mod_alias).
2061 [Ralf S. Engelschall]
2063 *) For binary builds, add -R flag to apachectl to work around the lack of
2064 an absolute path to the ./libexec directory where the libhttp.ep file
2065 is needed for SHARED_CORE architectures. [Randy Terbush]
2067 *) WIN32: Create the CGI script process as DETACHED. This may solve the
2068 problem observed by some Win95/98 users where they get CGI script
2069 output sent to the console. [Bill Stoddard]
2071 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
2072 routines are now called ap_base64* and are 'plain' (i.e., no
2073 pool access or anything clever). Inside util.c the routines acting
2074 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
2075 The oddly named ap_uuencode(), ap_uudecode() are kept around for
2076 now but deprecated. [dirkx]
2078 *) Clean up the base64 and SHA1 additions and make sure they are
2079 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
2080 files. [Roy Fielding]
2082 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
2083 checking. Allow compiling on VS 6.0. [Randy Terbush]
2085 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
2087 *) Use TestCompile to search for the truerand library (rather than blindly
2088 assuming its existence). If it is not found, complain (but do not
2089 exit - yet). [Martin Kraemer]
2091 *) We forgot to add the new exported function names to
2092 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
2094 *) Add description of -T command-line option to usage().
2095 [Ralf S. Engelschall]
2097 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
2098 searched only AFTER libap has been searched, because libap needs
2099 some symbols from libos. [Martin Kraemer]
2101 *) Fix conflict with original mod_digest related to the symbol of the
2102 module dispatch list (which has to be unique for DSO and follow the
2103 usual conventions for the installation procedure).
2104 [Ralf S. Engelschall]
2106 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
2107 for other platforms as well. [Martin Kraemer]
2109 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
2110 types by AP_LONG and replace reference to renamed variable 'ubuf'
2111 by 'buffer'. [Martin Kraemer]
2113 Changes with Apache 1.3.8 [not released]
2115 *) Flush the output buffer immediately after sending an error or redirect
2116 response, since the result may be needed by the client to abort a
2117 long data transfer or restart a series of pipelined requests.
2118 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
2120 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
2121 [Ian Turner <iant@sequent.com>] PR#4735
2123 *) Local struct mmap in http_core.c conflicted with system structure
2124 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
2126 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
2127 [Ronald Tschalär <ronald@innovation.ch>]
2129 *) Fix a memory leak where the module counts were getting messed
2130 up across restarts. [David Harris <dharris@drh.net>]
2132 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
2133 properly in mod_access.
2134 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
2136 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
2137 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
2139 *) PORT: Support for compaq/tandem/com.
2140 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
2142 *) Added SHA1 password encryption support to easy migration from
2143 Netscape servers. See support/SHA1 for more information.
2144 Caused the separation of ap_md5.c into md5, sha1 and a general
2145 ap_checkpass.c with just a validate_passwd routine. Added a
2146 couple of flags to support/htpasswd. Some reuse of the to64()
2147 function; hence renamed to ap_to64().
2148 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
2150 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
2151 with ASCII/EBCDIC conversions in "ident" query.
2152 [David McCreedy <McCreedy@us.ibm.com>]
2154 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
2155 Change "Power Macintosh" to Power* so if uname prints "Power Book"
2156 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
2158 *) Fix SIGSEGV on some systems because the Vary fix below included
2159 a call to table_do with a variable argument list that was not
2160 NULL terminated. Replaced with better implementation. [Roy Fielding]
2162 Changes with Apache 1.3.7 [not released]
2164 *) The "Vary" response header field is now sanitised right before
2165 the header is sent back to the client. Multiple "Vary" fields
2166 are combined, and duplicate tokens (e.g., "Vary: host, host" or
2167 "Vary: host, negotiate, host, accept-language") are reduced to
2168 single instances. This is a better solution than the force-no-vary
2169 one (which is still valid for clients that can't cope with Vary
2170 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
2172 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
2174 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
2175 least on Linux and FreeBSD for now.
2178 *) Win32: More apache -k restart work. Restarts are now honored
2179 immediately and connections in the listen queue are -not- lost.
2180 This is made possible by the use of the WSADuplicateSocket()
2181 call. The listeners are opened in the parent, duplicated, then
2182 the duplicates are passed to the child. The original listen sockets
2183 are not closed by the parent across a restart, thus the listen queue
2185 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2187 *) Fix handling of case when a client has sent "Expect: 100-continue"
2188 and we are going to respond with an error, but get stuck waiting to
2189 discard the body in the pointless hope of preserving the connection.
2190 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
2192 *) Fix 'configure' to work correctly with SysV-based versions of
2193 'tr' (consistent with Configure's use as well). [Jim Jagielski]
2195 *) apxs: Add "-S var=val" option which allows for override of CFG_*
2196 built-in values. Add "-e" option which works like -i but doesn't
2197 install the DSO; useful for editing httpd.conf with apxs. Fix
2198 editing code so that multiple invocations of apxs -a will not
2199 create duplicate LoadModule/AddModule entries; apxs can now be
2200 used to re- enable/disable a module. [Wilfredo Sanchez]
2202 *) Win32: Update the server to use Winsock 2. Specifically, link with
2203 ws2_32.lib rather than wsock32.lib. This gives us access to
2204 WSADuplcateSocket() in addition to some other enhanced comm APIs.
2205 Win 95 users may need to update their TCP/IP stack to pick up
2206 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
2207 [Bill Stoddard stoddard@raleigh.ibm.com]
2209 *) Win32: Redirect CGI script stderr (script debug info) into the
2210 error.log when CGI scripts fail. This makes Apache on Win32
2211 behave more like Unix.
2212 [Bill Stoddard stoddard@raleigh.ibm.com]
2214 *) Fixed `httpd' usage display: -D was missing.
2215 [Ralf S. Engelschall] PR#4614
2217 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
2218 [Ralf S. Engelschall] PR#4561, PR#4562
2220 *) OS/2: Fix problem with accept lock semaphores where server would die with
2221 "OS2SEM: Error 105 getting accept lock. Exiting!"
2222 [Brian Havard] PR#4505
2224 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
2225 [Randy Terbush <randy@covalent.net>]
2227 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
2228 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
2230 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
2231 command potentially _is_ GCC. [Ralf S. Engelschall]
2233 *) Fix apxs build issues on AIX
2234 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
2236 *) DocumentRoot Checking: Under previous versions, when Apache
2237 first started up, it used to do a stat of each DocumentRoot to
2238 see if it existed and was a directory. If not, then an error
2239 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
2240 does not exist, you will get error messages in error_log. If
2241 the '-t' command line option is used (to check the configuration)
2242 the check of DocumentRoot IS performed. An additional command
2243 line option, '-T', has been added if you want to avoid the
2244 DocumentRoot check even when checking the configuration.
2247 *) Win32: The query switch "apache -S" didn't exit after showing the
2248 vhost settings. That was inconsistent with the other query functions.
2249 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
2251 *) Win32: Changed behaviour of apache -k restart.
2252 Previously, the server would drain all connections in the stack's
2253 listen queue before honoring the restart. On a busy server, this
2254 could take hours. Now, a restart is honored almost immediately.
2255 All connections in Apache's queues are handled but connections in
2256 the stack's listen queue are discarded. Restart triggered by
2257 MaxRequestPerChild is unchanged.
2258 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2260 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
2261 the accept loop. Good for a 5% performance boost. Cleaned up
2262 parent/child process management code.
2263 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2265 *) Added ceiling on file size for memory mapped files.
2266 [John Giannandrea <jg@meer.net>] PR#4122
2268 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
2269 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
2270 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
2272 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
2273 use this at least for Expat. [Ralf S. Engelschall]
2275 *) Allow .module files to specify libraries with Lib:.
2278 *) Allow SetEnvIf[NoCase] to test environment variables as well
2279 as header fields and request attributes. [Ken Coar]
2281 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
2282 content-types are "text/html;parameters". PR#4524 [Ken Coar]
2284 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
2285 never accepted into any standard, and it opens up certain DoS
2286 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
2288 *) TestCompile updated. We can now run programs and output the
2289 results during the Configure process. [ Jim Jagielski]
2291 *) The source is now quad (long long) aware as needed. Specifically,
2292 the Configure process determines the correct size of off_t and
2293 *void. When the OS/platform/compiler supports quads, ap_snprintf()
2294 provides for the 'q' format qualifier (if quads are not available,
2295 'q' is silently "demoted" to long). [Jim Jagielski]
2297 *) When the username or password fed to htpasswd is too long, include the
2298 size limit in the error message. Also report illegal characters
2299 (currently only ':') in the username. Add the size restrictions
2300 to the man page. [Ken Coar]
2302 *) Fixed the configure --without-support option so it doesn't result in
2303 an infinite loop. [Marc Slemko]
2305 *) Piped error logs could cause a segfault if an error occured
2306 during configuration after a restart.
2307 [Aidan Cully <aidan@panix.com>] PR#4456
2309 *) If a "Location" field was stored in r->err_headers_out rather
2310 than r->headers_out, redirect processing wouldn't find it and
2311 the server would core dump on ap_escape_html(NULL). Check both
2312 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
2313 if Location isn't set. [Doug MacEachern, Ken Coar]
2315 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
2316 of the Expat 1.0.2 distribution. [Greg Stein]
2318 *) Replace regexec() calls with calls to a new API stub function
2319 ap_regexec(). This solves problems with DSO modules which use the regex
2320 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
2322 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
2323 environment variables can be set according to the protocol version
2324 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
2326 *) Add DSO support for OpenStep (Mach 4.2) platform.
2327 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
2329 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
2330 [Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
2332 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
2333 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
2335 *) Better DSO flags recognition on NetBSD platforms using ELF.

2341 *) Support for server-parsed and multiview-determined ReadmeName and
2342 HeaderName files in mod_autoindex. Removed the restriction on
2343 "/"s in ReadmeName and HeaderName directives since the *sub_req*
2344 routines will deal with the access issues. (It's now possible to

2576 *) proxy ftp: instead of using the hardwired string "text/plain" as
2577 a fallback type for files served by the ftp proxy, use the
2578 ap_default_type() function to determine the configured type.
2579 This allows for special configurations like
2580 <Directory proxy:ftp://some.host>
2581 DefaultType gargle/blurb
2583 Additionally, add the Content-Encoding: header to FTP proxy replies
2584 when the encoding is defined (by the AddEncoding directive).
2585 Because it was missing, it was almost impossible to browse compressed
2586 files using the FTP proxy (works now perfectly in Communicator).
2587 The ftp proxy now also returns the Date: and Server: header lines (if not
2588 much else... This code is "somewhat" broken) like normal requests do.

2668 for 8-bit safeness. [Dean Gaudet]
2670 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
2671 because SPARCs have a small machine-specific maximum size for the Global
2672 Offset Table which is often exceeded when compiling one of the larger
2673 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
2675 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the

2708 *) In configure, do not append the target name to the directory path if
2709 the path already contains "apache". [Ralf S. Engelschall]
2711 *) SIGPIPE is now ignored by the server core. The request write routines
2712 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
2713 correctly check for output errors and mark the connection as aborted.
2714 Replaced many direct (unchecked) calls to ap_b* routines with the
2715 analogous ap_r* calls. [Roy Fielding]
2717 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
2718 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
2719 Furthermore map lookups for non-existent keys are now cached as well.
2720 Additionally "txt" maps are now parsed with simple string functions
2721 instead of using ap_pregcomp(). As a side effect a bug that prevented
2722 the usage of keys containing the "," character was fixed.
2723 The changes drastically improve the performance when large rewrite maps
2725 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160

2733 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
2734 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
2736 *) Add %V to mod_log_config, this logs the hostname according to the
2737 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
2738 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
2740 *) Add support for \n and \t to mod_log_config, can be used to produce
2741 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
2743 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]

2762 as well and added some missing descriptions. Thanks!

2766 characters in the range 0x80 to 0xff (for example accented characters).

2769 *) Added conditional logging based upon environment variables to
2770 mod_log_config. mod_log_referer and mod_log_agent
2771 are now deprecated. [Ken Coar]
2773 *) Allow apache acting as a proxy server to relay the real
2774 reason of a failure to a client rather than the "internal
2775 server error" it does currently. The general exposure mechanism
2776 can be triggered by any module by setting the "verbose-error-to"
2777 note to "*"; this allows more than just proxy errors to be exposed.

2783 *) Added -S option to install.sh so that options can be passed to
2784 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
2786 *) Tweak modules Makefile generated by Configure so that it handles
2787 the test case of no modules being selected. [chaz@reliant.com]
2789 *) Added a <LimitExcept method ...> sectioning directive that allows
2790 the user to assign authentication control to any HTTP method that
2791 is *not* given in the argument list; i.e., the logical negation
2792 of the <Limit> directive. This is particularly useful for controlling
2793 access on methods unknown to the Apache core, but perhaps known by
2794 some module or CGI script. [Roy Fielding, Tony Finch]
2796 *) Prevent apachectl from complaining if the PIDFILE exists but
2797 does not contain a process id, as might occur if the server is
2798 being rapidly restarted. [Wilfredo Sanchez]
2800 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
2802 *) Entity tag comparisons for If-Match and If-None-Match were not being

2804 strong comparison wasn't properly enforced in all cases.
2805 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657

2810 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
2811 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
2813 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
2814 to util.c for parsing an HTTP header field value to extract the next
2815 list item, taking into account the possible presence of nested comments,
2816 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
2817 insignificant whitespace and lowercases non-quoted tokens.
2818 [Roy Fielding] PR#2065
2820 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
2821 code different from 500. This allows the proxy to, e.g., return
2822 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
2824 *) Fix ordering of language variants for the case where the traditional
2825 negotiation algorithm is being used with multiple language variants
2826 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
2828 *) Do not round the TCN quality calculation to 5 decimal places,
2829 unlike RFC 2296, because the calculation might need 12 decimal places
2830 to get the right result. [Roy Fielding]
2832 *) Remove unused code to disable transparent negotiation when
2833 negotiating on encoding only, as we now handle encoding too
2834 (though this is nonstandard for TCN), remove charset=ISO-8859-1
2835 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
2836 some debugging statements within mod_negotiation. [Koen Holtman]
2838 *) Fixed a rare memory corruption possibility in mod_dir if the index
2839 file is negotiable and no acceptable variant can be found.
2840 [Dean Gaudet, Roy Fielding, Martin Kraemer]
2842 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
2843 searching the Win32 registry for script interpreters.
2846 *) Win32: The compiled-in default filename for the error log is now
2847 error.log, which matches the default in the distributed httpd.conf.
2850 *) Win32: Any error messages from -i or -u command line options are now
2851 displayed on the console output rather than sent to the error log.
2852 Also the "Running Apache..." message is not output unless Apache is
2853 going to serve requests. [Paul Sutton]
2855 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
2856 and use a private significator ('$apr1$') to mark passwords as
2857 being smashed with our own algorithm. Also abstract the password
2858 checking into a new ap_validate_password() routine. [Ken Coar]
2860 *) Win32: The filename validity checker now allows "COM" but refuses
2861 access to "COM1" through "COM4". This allows filenames such
2862 as "com.name" to be served. [Paul Sutton] PR#3769.
2864 *) BS2000: Adapt to the new ufork() system call interface which will
2865 make subtasking easier on the OSD/POSIX mainframe environment.
2868 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
2869 ap_compat.h. [David White <david@persimmon.com>] PR#3725
2871 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
2872 use `.db' instead of `.pag' not only for FreeBSD, but also when
2873 the NDBM library looks like Berkeley-DB based.
2874 [Ralf S. Engelschall] PR#3773
2876 *) Add ability to handle DES or MD5 authentication passwords.
2877 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
2879 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
2881 *) SECURITY: Avoid some buffer overflow problems when escaping
2882 quoted strings. (This overflow was on the heap and we believe
2883 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
2885 *) Let src/Configure be aware of CFLAGS options starting with plus
2886 signs as it's the case for the HP/UX compiler.
2887 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
2889 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
2890 and check to see if the tar we wind up with supports '-h'.
2891 [Jim Jagielski] PR#3671
2893 *) A consistent and conservative style for all shell scripts has been
2894 implemented. Basically, all shell string tests use the traditional
2895 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
2896 to protect against bare null variable strings (ie: wrapping both
2897 sides with double quotes and prepending 'x'). 'x' was chosen
2898 because it's more universal and hopefully easier for old shell
2899 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
2902 *) The status module now prints out both the main server generation as
2903 well as the generation of each process. Also, the vhost info is
2904 printed with '?notable'. [Jim Jagielski]
2906 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
2907 and this makes its functions available to things in src/support.
2910 Changes with Apache 1.3.4
2912 *) Renamed macros status_drops_connection to ap_status_drops_connection
2913 and vestigial scan_script_header to ap_scan_script_header_err,
2914 mostly for aesthetic reasons. [Roy Fielding]
2916 *) The query switch "httpd -S" didn't exit after showing the
2917 vhost settings. That was inconsistent with the other query functions.
2920 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
2921 filename to the end of the STANDARD_MODULE_STUFF. Its
2922 presence at the beginning prevented reporting of the filename
2923 for modules compiled before 1 January 1999. [Ken Coar]
2925 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
2926 to detect and prevent access to special DOS device file names.
2927 [Paul Sutton, Ken Parzygnat]
2929 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
2930 and Makefile_win32_debug.txt (debug build) that work on Win95.
2931 Run each of the following from the src directory:
2932 nmake /f Makefile_win32.txt # compiles normal build
2933 nmake /f Makefile_win32.txt install # compiles and installs
2934 nmake /f Makefile_win32.txt clean # removes compiled junk
2935 nmake /f Makefile_win32_debug.txt # compiles debug build
2936 nmake /f Makefile_win32_debug.txt install
2937 nmake /f Makefile_win32_debug.txt clean
2940 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
2941 to build binary distributions. [Lars Eilebrecht]
2943 *) IndexOptions SuppressColumnSorting only turned off making
2944 the column headers anchors; you could still change the display
2945 order by manually adding a '?N=A' or similar query string to the
2946 URL. Now SuppressColumnSorting locks in the sort order so
2947 it can't be overridden this way. [Ken Coar]
2949 *) Added IndexOrderDefault directive to supply a default sort order
2950 for FancyIndexed directory listings. [Ken Coar] PR#1699
2952 *) Change the ap_assert macro to a variant that works on all platforms.
2953 [Richard Prinz <richard.prinz@cso.net>] PR#2575
2955 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
2956 search for an underscore on dlsym() (as it's already the case
2957 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
2959 *) Small fix for mod_env.html: The module was documented as to be _not_
2960 compiled into Apache per default, although it _IS_ compiled into
2961 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
2963 *) Instead of fixing a bug in the generation procedure for config.status (a
2964 backslash was missing) we remove the bug together with it's complete
2965 context because the special cases of the past can now no longer occur
2966 because of the recent magic for the --with-layout default.
2967 [Ralf S. Engelschall] PR#3590
2969 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
2970 making sure the src/support/ tools are _forced_ to be build last (they
2971 depend on other libraries).
2972 [Markus Theissinger <markus.theissinger@gmx.de>]
2974 *) Fix installation procedure: Now that os-inline.c is actually used (a
2975 recently fixed bug prevented this) we need to also install os-include.c
2976 in addition to os.h into the PREFIX/include/ location or building of
2977 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
2979 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
2980 allow us to distinguish between a garbled DSO (or even a file which isn't
2981 an Apache module DSO at all) and a DSO which doesn't match the current
2982 Apache API. [Ralf S. Engelschall] PR#3152
2984 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
2985 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
2986 match case insensitive (this especially avoids nasty patterns like
2987 `[tT][eE][sS][tT]'). Second two additional internal map functions
2988 `escape' and `unescape' were added which can be used to escape/unescape
2989 to/from hex-encodings in URLs parts (this is especially useful in
2990 combination with map lookups).
2991 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
2993 *) Renamed the macro escape_uri() to ap_escape_uri() which was
2994 forgotten (because it was a macro) in the symbol renaming process.
2995 [Ralf S. Engelschall]
2997 *) Fix some inconsistencies related to the scopes of directives. The only
2998 user visible change is that the directives `UseCanonicalName' and
2999 `ContentDigest' now use the (more correct) `Options' scope instead of
3000 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
3002 *) Using DSO, the Server token was being mangled. Specifically, the
3003 module's token was being added first before the Apache token. This
3004 has been fixed. [Jim Jagielski]
3006 *) Major overhaul of mod_negotiation.c, part 2.
3007 - properly handle "identity" within Accept-Encoding.
3008 - allow encoded variants in RVSA negotiation and let them appear in
3009 the Alternates field using the non-standard "encoding" tag-list.
3010 - fixed both negotiation algorithms so that an explicitly accepted
3011 encoding is preferred over no encoding if "identity" is not
3012 included within Accept-Encoding.
3013 - added ap_array_pstrcat() to alloc.c for efficient concatenation
3014 of large substring sequences.
3015 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
3018 *) Major overhaul of mod_negotiation.c, part 1.
3019 - cleanups to mod_negotiation comments and code structure
3020 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
3021 support for everything in the upcoming HTTP/1.1
3022 revision (draft-ietf-http-v11-spec-rev-06.txt).
3023 - language tag matching also handles tags with more than 2
3025 - empty Accept, Accept-Language, Accept-Charset headers are
3026 processed correctly; previously an empty header would make all
3027 values acceptable instead of unacceptable.
3028 - allowed for q values in Accept-Encoding
3029 - added support for transparent content negotiation (rfc2295 and
3030 rfc2296) (though we do not implement all features in these drafts,
3031 e.g. no feature negotiation). Removed old experimental version.
3032 - implemented 'structured entity tags' for better cache correctness
3033 (structured entity tags ensure that caches which can deal with Vary
3034 will (eventually) be updated if the set of variants on the server
3036 - this involved adding a vlist_validator element to request_rec
3037 - this involved adding the ap_make_etag() function to the global API
3038 - modified guessing of charsets used by Apache negotiation algorithm
3039 to guess 'no charset' if the variant is not a text/* type
3040 - added code to sort multiviews variants into a canonical order so that
3041 negotiation results are consistent across backup/restores and mirrors
3042 - removed possibility of a type map file resolving to another type map
3043 file as its best variant
3044 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
3046 *) RFC2396 allows the syntax http://host:/path (with no port number)
3047 but the proxy disallowed it (ap_proxy_canon_netloc()).
3048 [David Kristol <dmk@bell-labs.com>] PR#3530
3050 *) When modules update/modify the file name in the configfile_t structure,
3051 syntax errors will report the updated name, not the original one.
3052 [Fabien Coelho <coelho@cri.ensmp.fr>] PR#3573
3054 *) Correct some filename case assumptions from WIN32 to
3055 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]
3057 *) For %v log ServerName regardless of the UseCanonicalName
3058 setting (similarly for %p). [Dean Gaudet]
3060 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
3061 rather late (too late for some invocations of TestCompile).
3062 This improves the make environment available to TestCompile and
3063 the *.module scripts. [Martin Kraemer]
3065 *) The hashbang emulation code in ap_execve.c would interpret
3066 #!/hashbang/scripts correctly, but failed to fall back to a
3067 standard shell for scripts which did NOT start with #!
3068 Now SHELL_PATH is started in these cases. [Martin Kraemer]
3070 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
3073 *) Update APXS manual page: some -q option arguments were missing
3074 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
3076 *) Cleanup the command line options: `-?' was documented to show
3077 the usage list but does it with an error because `?' is not a valid
3078 command. OTOH a lot of users expect `-h' to print such a usage list and
3079 instead are annoyed for ages by our huge unreadable list of directives.
3080 So we now changed the command line options this way:
3082 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
3083 very similar to the popular linker option.
3085 Intent: while -l gives the small list of modules, -L now gives the
3086 large list of directives implemented by these modules. This is also
3087 consistent with -v (short version info) and -V (large version info).
3089 Intent: it's now the expected option ;-)
3090 The manual page was adjusted accordingly.
3091 [Ralf S. Engelschall] PR#2714
3093 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
3094 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
3096 *) Removed recently introduced bugs and disfigurements in APACI:
3097 o fixed argument line processing: using $args was broken: It was not
3098 initialized and using args="$args $apc_option" and even args="$args
3099 \"$apc_option\"" fails in the second processing round for any arguments
3100 containing whitespaces. The only correct way is to use the construct
3101 "$@" (but not possible here) or iterate _both_ times over the implicit
3102 argument line (no argument to for-loop) which is what we now use.
3103 o make --with-layout=Apache the default without creating
3104 redundancy (copying the --with-layout block in the argument parsing
3105 loop). We achieve this by using the "$@" construct together with the
3106 `set' command to prepend --with-layout=Apache to the command line in
3107 case --with-layout is not used.
3108 o fixed auto-suffix handling now that config.layout exists.
3109 Paths which are auto-suffixed are marked with a trailing plus sign in
3110 config.layout and every path now can be marked this way (not only the
3111 four paths for which we do it currently). Additionally the suffix is
3112 no longer a static one. Instead it's now `/<target>' where <target> is
3113 the argument of the --target option or per default `httpd'.
3114 o allow also tabs (and only spaces) where we match whitespaces
3115 o various fixes and cleanups related to used shell coding style
3116 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
3117 o trimmed output of --help to fit into 80 columns
3118 [Ralf S. Engelschall]
3120 *) Added two new core API functions, ap_single_module_configure() and
3121 ap_single_module_init(), which are now used by mod_so to configure a module
3122 after loading. [Ralf S. Engelschall]
3124 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
3125 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
3126 of ap_config.h to allow serialized accept for multiport listens.
3127 [Roy Fielding, Curt Sampson] PR#3120
3129 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
3130 of ap_config.h that would skip several defines if DEFAULT_GROUP
3131 was overridden. [Roy Fielding]
3133 *) PORT: The I86 version of DGUX has support for strncasecmp and
3134 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
3136 *) Fix ordering of definitions in ap_config.h so that ap_inline is
3137 defined before it might be used. [Victor Khimenko]
3139 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
3140 [Tom Serkowski <tks@bsdi.com>] PR#3453
3142 *) Make generation of src/Configuration.apaci more robust: It failed to
3143 differenciate between modules when one module name was a postfix of
3144 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
3145 just XXX (think about totally non-standard names like "apache_ssl", too).
3146 [Ralf S. Engelschall] PR#3380
3148 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
3149 since 1.3b7) and make whitespace handling more robust (it failed horrible
3150 when whitespaces were present in the arguments of -D options).
3151 [Ralf S. Engelschall] PR#3240
3153 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
3154 creates an external package shadow tree in DIR before the local build
3155 shadow tree is generated under DIR. This way one can have the extracted
3156 Apache distribution tree read-only on NFS or CDROM and still build Apache
3157 from these sources. An automatically triggered VPATH-like mechanism is
3158 provided through the TOP variable, too.
3159 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez@apple.com>]
3161 *) Fix negotiation so that a Vary response header is correctly
3162 generated when, for a particular dimension, variants only vary
3163 in having or not having a value for that dimension. [Paul Sutton]
3165 *) Fix negotiation so that we prefer an encoded variant over an
3166 unencoded variant if the user-agent explicitly says it can
3167 accept that encoding. Previously we always preferred the unencoded
3169 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
3171 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
3172 and the usage page was inconsistent with the functionality and manpage.
3173 [Ralf S. Engelschall]
3175 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
3176 They can occur multiple times and their arguments (`xxx') are passed AS
3177 IS to the compiler/linker command. [Ralf S. Engelschall]
3179 *) Fixed possible (but harmless in practice) bug in the DBM lookup
3180 procedure of mod_rewrite: very long keys were truncated.
3181 [Ralf S. Engelschall]
3183 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
3184 identifier, currently "Apache" and "GNU" are pre-defined in the file
3185 config.layout. Custom layouts are possible by using FILE:ID as the
3186 argument where the layout ID is taken from FILE.
3188 The config.layout file consists of <Layout ID>..</Layout> sections
3189 where inside those sections "path_variable: path_value" pairs can be
3190 specified. These lines are converted to path_variable='path_value'.
3192 *) Add a DefaultLanguage directive so that files missing a language
3193 extension (e.g., .fr, .de) can be labelled as being some other
3194 default language. DefaultLanguage can appear in <Directory> and
3195 <Files> containers as well as .htaccess files. [Paul Sutton]
3198 *) Fix TARGET configuration when configuring and installing using
3199 APACI configure. TARGET now defines the basename of the configuration
3200 file, startup script, manual page, etc. log_error_core() now reports
3201 the server binary name given by argv[0]. TARGET can now also be defined
3202 with --target=TARGET parameter passed to APACI configure.
3203 [Ralf Engelschall, Randy Terbush]
3205 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
3206 rather than OPT_INCLUDES [Rainer Schoepf <schoepf@uni-mainz.de>]
3208 *) ap_md5_binary() was using sprintf() rather than a table lookup
3209 to convert binary bytes to hex digits.

3226 and a redirect at the same time. [Lars Eilebrecht]
3228 *) Fallback to native compilers for IRIX-32 platform. It seems that
3229 a gcc 2.8.1 compiled apache is logging client addresses with all
3230 bits set (255.255.255.255). This is the second such problem caused
3231 by gcc 2.8.1 compiler. The first being broken semaphore locking.
3234 *) Updated mime.types to reflect current Internet media types

3309 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
3310 in the Configuration[.apaci] file. Two special and important variants are
3311 supported for the option argument: first BEGIN:foo which permutes module
3312 mod_foo with the begin of the module list, i.e. it `moves' the module to
3313 the begin of the list (gives it lowest priority). And second foo:END
3314 which permutes mod_foo with the end of the module list, i.e. it `moves'
3315 the module to the end of the list (gives it highest priority).

3342 *) Fix Berkeley-DB/2.x support in mod_auth_db: The data structures were not

3347 [Ralf S. Engelschall, Ron Record <rr@sco.com>]
3349 *) Merge the contents of the {srm,access}.conf-dist* files into the
3350 httpd.conf-dist* files. The srm and access files now contain
3351 only comments, and httpd.conf has all the combined contents in
3352 a rational order. [Ken Coar]
3354 *) PORT: DSO/ELF support for FreeBSD 3.0.
3355 [Ralf S. Engelschall, Dirk Froemberg <ibex@physik.TU-Berlin.DE>]
3357 *) Add a "default-handler" handler that calls the default_hander()
3358 function which is normally called for static content. This allows
3359 you to override a specific handler. [Marc Slemko]
3361 *) Further simplify checking for absolute paths by replacing an
3362 hard-coded syntax check with a call to a routine we already created to
3363 do this. [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2976, 3074
3365 *) Log an error if we encounter a malformed "require" directive
3366 in mod_auth if we know that we know that no other module can
3367 deal with it. [Marc Slemko]
3369 *) Remove ap_private_extern method of hiding conflicting symbols
3370 on the NEXT platform because it is not correct for all versions,
3371 and the versions for which it is correct are unknown.

3378 is encountered in an .htaccess file somewhere down the tree.
3381 *) Minor performance improvement to ap_escape_html(). [Roy Fielding]
3383 *) Fixed a segmentation violation in mod_proxy when a response is
3384 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
3386 Changes with Apache 1.3.3
3388 *) Added a complete implementation of the Expect header field as
3389 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
3390 response when we already know the final status, which is mighty
3391 useful for PUT responses that result in 302 or 401. [Roy Fielding]
3393 *) Remove extra trailing whitespace from the getline results as part
3394 of the protocol processing, which is extra nice because it works
3395 between continuation lines, is almost no cost in the normal case
3396 of no extra whitespace, and saves memory. [Roy Fielding]
3398 *) Added new HTTP status codes and default response bodies from the
3399 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
3400 HTTP Extension Framework (510) specifications. Did not add the
3401 WebDAV 424 and 425 codes because they are bogus. We don't use any
3402 of these codes yet, but they are now available to 3rd-party modules.
3405 *) Fix a possible race condition between timed-out requests and the
3406 ap_bhalfduplex select that might result in an infinite loop on
3407 platforms that do not validate the descriptor. [Roy Fielding]
3409 *) WIN32: Add "-k shutdown" and "-k restart" options to signal a

3413 of "-". [Martin Plechsmid <plechsmi@karlin.mff.cuni.cz>, Marc Slemko]

3423 [M. Laak <maert@proinv.ee>] PR#3108

3426 calculation in mod_status for all systems which don't have POSIX
3427 sysconf() (like UTS 2.1) and not only for the NEXT platform.

3430 *) Fix `require ...' directive parsing in mod_auth, mod_auth_dbm and
3431 mod_auth_db by using ap_getword_white() (which uses ap_isspace())

3433 but not tabs). [James Morris <jmorris@intercode.com.au>,

3475 <steve.cameron@compaq.com>]
3477 *) Reconstructed the loop through multiple htaccess file names so
3478 that missing files are not confused with unreadable files.
3481 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
3482 errno on an error, which leads to one error being mistaken for
3483 another when reading non-existent .htaccess files.
3486 *) OS/2: The new header tests get things right, need to update

3504 Changes with Apache 1.3.2
3506 *) Fix bug in ap_remove_module(), which caused problems for dso's
3507 who were the top_module. [Doug MacEachern]
3509 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
3510 mod_auth_db to both be friendly to users who wants to use this version
3511 and to avoid problems under platforms where only version 2.x is present.
3512 [Dan Jacobowitz <drow@false.org>, Ralf S. Engelschall]
3514 *) When using ap_log_rerror(), make the error message available to the
3515 *ERROR_NOTES envariables by default. [Ken Coar]
3517 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
3518 You now must define a BS2000Account name for the server User.
3519 This has fewer security implications than the old approach.
3522 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
3523 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
3524 platform to make the braindead HPUX linker happy. Notice, for the module
3525 DSOs we don't have to use this, because these are loaded manually (and
3526 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
3528 *) Remove 64 thread limit on Win32.
3529 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3531 *) Remove redundant substitutions in top-level Makefile.tmpl.
3532 [Ralf S. Engelschall]
3534 *) Fix APACI's `Group' configuration adjustment - especially for Linux
3535 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
3537 *) Make PrintPath work generically instead of having one version
3538 strictly for OS/2. [Jim Jagielski, Brian Havard]
3540 *) Fix the recently introduced C header file checking: We now use the C
3541 pre-processor pass only (and no longer the complete compiler pass) to
3542 determine whether a C header file exists or not. Because only this way
3543 we're safe against inter-header dependencies (which caused horrible
3544 portability problems). The only drawback is that we now have a CPP
3545 configuration variable which has to be determined first (we do a similar
3546 approach as GNU Autoconf does here). When all fails the user still has
3547 the possibility to override it manually via APACI or src/Configuration.
3548 As a fallback for the header check itself we can directly check the
3549 existance of the file under /usr/include, too.
3550 [Ralf S. Engelschall] PR#2777
3552 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined
3553 as an alternate mechanism for mmap'd shared memory for RHAPSODY.
3554 ap_private_extern defined to hide symbols that conflict with loaded
3555 dynamic libraries on the NEXT and RHAPSODY platforms.

3574 used -lprot. It's actually a bug in SCO5, of course.

3577 *) Fix documentation of ProxyPass/ProxyPassReverse according to the
3578 trailing slash problem. [Jon Drukman <jsd@gamespot.com>] PR#2933
3580 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
3581 platform, because it's only supported under version 4.0 and higher. But
3582 because our GuessOS is still unaware of Digital UNIX versions and the
3583 -msym is just to optimize the DSO statup time a little bit it's safe and
3584 best when we leave it out now. [Ralf S. Engelschall] PR#2969
3586 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
3587 functions: First all three functions no longer fail on strings containing
3588 "%" chars and second ap_log_printf() no longer does a double-formatting
3589 (instead it directly passes through the message to be formatted to the
3590 real internal formatting function). [Ralf S. Engelschall] PR#2941
3592 *) Allow "Include" directives anywhere in the server config
3593 files (but not .htaccess files). [Ken Coar] PR#2727
3595 *) The proxy was refusing to serve CONNECT requests except to
3596 port 443 (https://) and 563 (snews://). The new AllowCONNECT
3597 directive allows the configuration of the ports to which a
3598 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
3600 *) mod_expires will now act on content that is not sent from a file
3601 on disk. Previously it would never add an Expires: header to
3602 any response that did not come from a file on disk; the only
3603 case where it still doesn't (and can't) add one for that type of
3604 content is if you are using a modification date based setting.
3605 [Marc Slemko, Paul Phillips <paulp@go2net.com>]
3607 *) Problems encountered during .htaccess parsing or CGI execution
3608 that lead to a "500 Server Error" condition now provide explanatory
3609 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
3612 *) Add NameWidth keyword to IndexOptions directive so that the
3613 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
3616 *) Recognize lowercase _and_ uppercase `uname' results under
3617 SCO OpenServer. [David Coelho <drc@ppt.com>]
3619 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
3620 a common problem of (mis-administrated?) IIS servers, make the apache
3621 proxy immune to these errors (and ignore the duplicates, but log
3622 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
3624 *) The <IfModule and <IfDefine block starting directives now only
3625 allow exactly one argument. Previously, the optional negation
3626 character '!' could be separated by whitespace without a syntax
3627 error being reported, albeit defeating the IfModule functionality
3628 (enclosed directives would ALWAYS be executed). By using the
3629 stricter syntax, these hard-to-track errors can be avoided.
3632 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
3633 cause the standalone FancyIndexing directive to logically OR
3634 into any existing IndexOptions settings rather than wiping
3635 them out. [Ken Coar]
3637 *) Changes in ftp proxy: make URL parsing simpler by using the
3639 + Add display of the "current directory" in cases where it's
3640 different from the supplied path (e.g., ftp://user@host/ lives
3641 in /home/user, not in /, therefore clicking on "../" in the
3642 starting directory might send us to /home/).
3643 + When ftp login fails, (esp. when a user name was part of the
3644 URL already), we now return [401 Unauthorized ] to allow the
3645 browser to pop up an authorization dialog. This makes passwords
3646 slightly less visible (they don't appear in the regular log files)
3647 and implements a functionality that other www proxy servers
3651 *) Triggered by the recent "Via:" header changes, the proxy module would
3652 dump core for replies with invalid headers (e.g., duplicate
3653 "HTTP/1.0 200 OK" lines). These errors are now logged and the
3654 core dump is avoided. Also, broken replies are not cached.
3655 [Martin Kraemer] PR#2914
3657 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
3658 plop gmon.out profile data for each child [Doug MacEachern]
3660 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
3661 config.status script to be immune against arguments with whitespaces.
3662 [Yves Arrouye <yves@apple.com>] PR#2866
3664 *) Replace the inlined information grabbing stuff for the configuration
3665 adjustment feature (no --without-confadjust) with calls to a new helper
3666 script `buildinfo.sh' which is both more flexible and already proofed to
3667 be more robust against platform differences. This mainly fixes the
3668 recently occured ``sed: command garbled: ...'' problems.
3669 [Ralf S. Engelschall] PR#2776, PR#2848
3671 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
3672 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
3673 without complains after we recently added the POST feature.
3674 [Ralf S. Engelschall]
3676 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
3677 modules as API functions and we forgot them at the big symbol renaming.

3680 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html

3686 *) Add the ability to do POST requests to the ab benchmarking tool.
3687 [Kurt Sussman <kls@best.com>] PR#2871
3689 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
3690 5 to 10 because there are some users out there who always have 5 to 8
3691 variables in one RewriteRule and had to patch mod_rewrite.h for every
3692 release. So 15 should be now more than enough, even for them. (I never
3693 needed more than 4 in my RewriteRules ;-)
3694 [Ralf S. Engelschall]
3696 *) Make the proxy generate and understand Via: headers
3699 *) Change the proxy to use tables instead of array_headers for
3700 the header lines. [Martin Kraemer]
3702 *) Make sure the config.status file is not overridden when just
3703 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
3705 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
3706 provide a way to trace API changes that add functionality but do
3707 not create a compatibility issue for precompiled modules, etc.
3708 See include/ap_mmn.h for more details. [Randy Terbush]
3710 *) Fix suexec installation under `make install root=xxx' situation.
3711 [Ralf S. Engelschall]
3713 *) Extend the output of the -V switch to include the paths of all
3714 compiled-in configuration files, if they were overridden at
3715 compile time, for least astonishment of the user.
3718 *) When READing a request in ExtendedStatus mode, the "old"
3719 vhost, request and client information is not displayed.
3722 *) STATUS is no longer available. Full status information now
3723 run-time configurable using the ExtendedStatus directive.
3726 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
3727 cpu time attacks) in header parsing. Add ap_overlap_tables(),
3728 a function which can be used to perform bulk update operations
3729 on tables in a more efficient manner. [Dean Gaudet]
3731 *) SECURITY: Added compile-time and configurable limits for
3732 various aspects of reading a client request to avoid some simple
3733 denial of service attacks, including limits on maximum request-line
3734 size (LimitRequestLine), number of header fields (LimitRequestFields),
3735 and size of any one header field (LimitRequestFieldsize). Also added
3736 a configurable directive LimitRequestBody for limiting the size of the
3737 request message body. [Roy Fielding]
3739 *) Make status module aware of DNS and logging states, even if
3740 STATUS not defined. [Jim Jagielski]
3742 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
3744 *) Enhance mod_speling so that CheckSpelling can be used in

3748 ErrorDocument mechanism at runtime [Doug MacEachern]
3750 *) API: new ap_uuencode() function [Doug MacEachern]
3752 *) API: scan_script_header_err_core() now "public" and renamed
3753 ap_scan_script_header_err_core() [Doug MacEachern]
3755 *) The 'status' module will now show the process pid's and their
3756 state even without full STATUS accounting. [Jim Jagielski]
3758 *) Restore the client IP address to the error log messages, this
3759 was lost during the transition from 1.2 to 1.3. Add a new
3760 function ap_log_rerror() which takes a request_rec * and
3761 formats it appropriately. [Dean Gaudet] PR#2661
3763 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
3764 whitespace in input lines -- including within quoted strings.
3766 but leading and trailing whitespace should continue to be
3767 stripped [Martin Kraemer]
3769 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
3770 the ugly use of an env. variable and use command-line args for
3771 alternate $PATH. Make more like advanced 'type's as well.
3774 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
3775 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
3776 <alain.st-denis@ec.gc.ca>] PR#2736
3778 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
3780 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
3781 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
3782 directory was renamed to src/os/os2/ for consistency.
3783 [Brian Havard, Ralf S. Engelschall]
3785 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
3786 files (here modules) against other DSO files (here shared libraries).
3787 This is done by determining a subset of LIBS which can be safely used for
3788 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
3789 disabled for all platforms to avoid problems with this (experimental)
3790 rule. But we provide it now for those people how ran into problems and
3791 want to came out by forcing linking against DSOs.

3794 *) Fix suEXEC start message: Has to be of `notice' level to really get

3810 *) One more portability fix for APACI shadow tree support: Swap order of awk
3811 and sed in top-level configure script to avoid sed fails on some

4044 directory, bail out of the request with an error message. [W G Stoddard]

4047 these are treated by Win32 as if they are ".." but are not detected by
4048 other machinery within Apache. This is something of a kludge but
4049 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
4051 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses

4069 user. Package authors can use the --without-confadjust option to disable
4070 these configuration adjustments.

4079 as <IfModule>..</IfModule> sections) which can be used to skip or process
4080 contained commands dependend of ``-D PARAMETER'' options on the command
4081 line. This can be used to achieve logical conditions like <IfDefine
4082 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)

4084 modules via LoadModule, etc. [Ralf S. Engelschall]

4095 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
4096 in top-level configure script to avoid sed fails on some platforms (for
4097 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
4098 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
4100 *) Improve performance of directory listings (mod_autoindex) by comparing
4101 integer keys (last-modified and size) as integers rather than converting
4102 them to strings first. Also use a set of explicit byte tests rather
4103 than strcmp() to check for parent directory-ness of an entry. Oh, and
4104 make sure the parent directory (if displayed) is *always* listed first
4105 regardless of the sort key. Overall performance winnage should be good
4106 in CPU time, instruction cache, and memory usage, particularly for large
4107 directories. [Ken Coar]
4109 *) Add a tiny but useful goody to APACI's configure script: The generation
4110 of a config.status script (as GNU Autoconf does) which remembers the used
4111 configure command and hence can be used to restore the configuration by
4112 just re-running this script or for remembering the configuration between
4114 [Ralf S. Engelschall]
4116 *) Add httpd -t (test) option for running configuration syntax tests only.
4117 If something is broken it complains and exits with a return code
4118 non-equal to 0. This can be used manually by the user to check the Apache
4119 configuration after editing and is also automatically used by apachectl
4120 on (graceful) restart command to make sure Apache doesn't die on restarts
4121 because of a configuration which is now broken since the last (re)start.
4122 This way `apachectl restart' can be used inside cronjobs without having
4123 to expect Apache to be falling down. Additionally the httpd -t can be run
4124 via `apachectl configtest'.

4276 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
4277 was updated to use the normal apache error processing, thereby allowing
4278 proxy errors to be treated by ErrorDocument's as well. For this
4279 purpose, a new module-to-core communication variable "error-notes"
4280 was introduced; the proxy (and possibly other modules) communicates
4281 its error text using this variable. Its content is copied to a new
4282 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
4283 The old proxy special error routine ap_proxy_log_uerror()

4330 [Rick Ohnemus <rick@ecompcon.com>]
4332 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
4333 logfile instead of fiddling around itself with child spawning stuff.
4334 [Ralf S. Engelschall]
4336 *) Made RefererIgnore case-insensitive.
4338 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
4341 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
4342 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
4345 *) Improve RFC1413 support. [Bob Beck <beck@bofh.ucs.ualberta.ca>]
4347 *) Fix support script `dbmmanage': It was unable to handle some sort
4348 of passwords, especially passwords with "0" chars.
4349 [Ralf S. Engelschall] PR#2242
4351 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
4352 [Ben Laurie] PR#2238
4354 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
4355 library), so CGI handling has been changed to use Win32 native handles
4356 instead of C file descriptors.
4357 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
4359 *) The proxy cache would store an incorrect content-length in the cached
4360 file copy after a cache update. That resulted in repeated fetching
4361 of the original copy instead of using the cached copy.
4362 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
4364 *) The Makefiles assumed that DSO files are build via $(LD). This
4365 is broken for two reasons: First we never defined at least LD=ld
4366 somewhere to make sure this works (it was silently assumed that most Make
4367 provide a built-in LD definition - ARGL!) and second using the generic LD
4368 variable is not the truth. Instead a special variable named LD_SHLIB is
4369 reasonable because although "ld" is usually the default, the command for
4370 building DSO files can be "libtool" or even "cc" on some systems.
4371 [Ralf S. Engelschall]
4373 *) Replace the AddVersionPlatform directive with ServerTokens which
4374 provides for more control over the format of the Server:
4375 header line. SERVER_SUBVERSION is no longer supported;
4376 all module should use the ap_add_version_component()
4377 API function instead. [Jim Jagielski]
4379 *) Support for the NCR MP/RAS 3.0
4380 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
4382 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
4383 not retrieved in src/Configure and thus was not useable.
4384 [Ralf S. Engelschall]
4386 *) Various Makefile consistency cleanups:
4387 - make OSDIR also automatically be relative to src/ like INCDIR
4388 - SUBDIRS is now generated in src/Makefile only and not in
4389 Makefile.config because it is a local define for this location.
4390 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
4391 any Makefile but make sure that at least the "-K inline" is kept in
4393 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
4394 - updated the dependencies theirself
4395 - removed not existing SHLIB variable from "clean" targets
4396 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
4397 already exists and OBJS_PIC are also just plain objects and have not
4398 directly to do with "shared" things. The only difference is that they
4399 contain PIC. So OBJS_PIC is the more canonical name.
4400 - Updated the Makefile-dependency lines for OBJS_PIC
4401 - Removed the Makefile-dependency line in Configure to avoid double
4403 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
4404 of xxx.lo as GNU libtool does with its PIC objects
4405 - reduce local complexity in modules Makefile.tmpl by moving the last
4406 existing target "depend" to the generation section in Configure, too.
4407 - removed the historical $(SPACER) which was used in the past together
4408 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
4409 is no longer needed.
4410 - force the build and run of the gen_xxx programs under main/ as the
4411 first step before building the objects because it looks cleaner
4412 [Ralf S. Engelschall]
4414 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
4417 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
4420 *) WIN32: Don't force ISAPI headers to finish with \n.
4421 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
4423 *) When opening "configuration" files (like httpd.conf, htaccess
4424 and htpasswd), Apache will not allow them to be non-/dev/null
4425 device files. This closes a DoS hole. At the same time,
4426 we use ap_pfopen to open these files to handle timeouts.
4427 [Jim Jagielski, Martin Kraemer]
4429 *) Apache will now log the reason its httpd children exit if they exit
4430 due to an unexpected signal. (It requires a new porting define,
4431 SYS_SIGLIST, which if defined should point to a list of text
4432 descriptions of the signals available. See PORTING.) [Dean Gaudet]
4434 *) WIN32: chdir() doesn't make sense in a multithreaded environment
4435 like WIN32. Before, Win32 CGI's could have had sporadic failures
4436 if a chdir call from one thread was made between another chdir call
4437 and a spawn in another thread. So, for now don't chdir for CGI scripts
4438 in WIN32. The current CGI "spec" is unclear as to whether it's
4439 necessary. Long-term fix is to either serialize the chdir/spawn combo
4440 or use WIN32 native calls to spawn a process. This temp fix was
4441 necessary to remove this as a showstopper for 1.3's release.
4444 *) Cleanup the suEXEC support in APACI and make it more safe:
4445 1. Add big fat hint in INSTALL about risks and to read the
4446 htdocs/manual/suexec.html document before using the suexec-related
4448 2. Make sure the user has at least provided one --suexec-xxxx option
4449 (specifies suEXEC parameters) in addition to --enable-suexec option.
4450 If only --enable-suexec is given APACI stops with a hint to INSTALL
4451 and htdocs/manual/suexec.html documents.
4452 3. Provide two additional --suexec-xxxx options to make the suEXEC
4453 configuration complete (especially for package maintainers who else
4454 had to patch the source tree) by providing ways to configure minimal
4455 UID/GID and safe PATH, too.
4456 [Ralf S. Engelschall]
4458 *) Cleanup of the `configure --shadow' process:
4459 - make sure the configure script creates its temporary files in the
4460 shadow tree to avoid conflicts with parallel configure runs
4461 - removed unnecessary option "-r" from "rm" call for Makefiles
4462 - make sure the configure scripts creates the shadow-wrapper Makefile
4463 only when no shadow trees already exists
4464 - make sure "make distclean" removes the shadow-wrapper Makefile but only
4465 when no more shadow trees exists
4466 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
4467 as fast (in the past it needed 70sec, now it runs just 38sec)
4468 - make sure CVS does not complain about the created files
4469 Makefille.<gnutriple> and directories src.<gnutriple>
4470 [Ralf S. Engelschall]
4472 *) Added the ap_add_version_component() API routine and the
4473 AddVersionPlatform core directive. The first allows modules to
4474 declare themselves in the Server response header field value,
4475 augmenting the SERVER_SUBVERSION define in the Configuration file
4476 with run-time settings (more useful in a loadable-module environment).
4477 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
4478 into the server version string. [Ken Coar] PR#2056
4480 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
4483 *) Emit the "Accept-Range" header for the default handler.
4484 [Brian Behlendorf] PR#1464
4486 *) Add a note to httpd.conf-dist that apache will on some systems fail
4487 to start when the Group # is set to a negative or large positive value.
4490 *) Make sure the module execution order is correct even when some modules
4491 are loaded under runtime (`LoadModule') via the DSO mechanism:
4492 1. The list of loaded modules is now a dynamically allocated one
4493 and not the original statically list from modules.c
4494 2. The loaded modules are now correctly setup by LoadModule for
4495 later use by the AddModule command.
4496 3. When the DSO mechanism for modules is used APACI's `install'
4497 target now enables all created `LoadModule' lines per default because
4498 this is both already expected by the user _and_ needed to avoid
4499 confusion with the next point and reduces the Makefile.tmpl complexity
4500 4. When the DSO mechanism for modules is used, APACI's `install'
4501 target now additionally makes sure the module list is reconstructed
4502 via a complete `ClearModuleList+AddModule...' entry.
4503 5. The support tool `apxs' now also makes sure an AddModule command
4504 is added in addition to the LoadModule command.
4505 6. The modules.c generation was extended to now contain two
4506 comments to make sure no one is confused by the confusing terminology
4507 of loading/linking (we use load=link+load & link=activate instead of
4508 the obvious load=activate & link=link :-( )
4509 This way now there is no longer a difference under execution time between
4510 statically and dynamically linked modules.
4511 [Ralf S. Engelschall]
4513 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
4514 Big Symbol Renaming. [Ralf S. Engelschall]
4516 *) Add a comment to mod_example.c showing the format of a FLAG command
4519 *) Standardized the time format in mod_status to match that of other
4520 places in the code (e.g. DATE_GMT). PR#1551
4522 *) Fix handling of %Z in timefmt strings for those platforms with no time
4523 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
4526 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
4527 feature compatible with 'UseCanonicalName off' by changing
4528 r->server->server_hostname to ap_get_server_name(). And I changed some
4529 functions which use r->server->port to use ap_get_server_port() instead,
4530 because if there's no Port directive in the config r->server->port is 0.
4533 *) get/set_module_config are trivial enough to be better off inline. Worth
4534 1.5% performance boost. [Dean Gaudet]
4536 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
4537 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
4540 *) [BS2000 security] BS2000 needs an extra authentication to initialize
4541 the task environment to the unprivileged User id. Otherwise CGI scripts
4542 would have a way to gain super user access. [Martin Kraemer]
4544 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
4545 absolute path, only log base name of logging source as is done
4546 in unix. [Martin Kraemer]
4548 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
4549 the encoding type from the Accept-Encoding header (if it's there)
4550 and use it in the response, as that's probably what it'll be expecting.
4551 [Ronald.Tschalaer@psi.ch]
4553 *) Fix to mod_alias: translate_alias_redir is dealing with
4554 a URI, not a filename, so the check for drive letters for win32
4555 and emx is not necessary. [Dean Gaudet]
4557 *) WIN32: Allow .cmd as an executable extension.
4558 [Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146
4560 *) Make Apache header files, and some variables, C++ friendly.
4561 [Michael Anderson's <mka@redes.int.com.mx>]
4563 *) Child processes can now "signal" (by exiting with a status
4564 of APEXIT_CHILDFATAL) the parent process to abort and
4565 shutdown the server if the error in the child process was
4566 fatal enough. [Jim Jagielski]
4568 *) mod_autoindex's find_itme() was sensitive to MIME type case.
4569 [Jim Jagielski] PR#2112
4571 *) Make sure the referer_log and agent_log entries in the default httpd.conf
4572 file are also adjusted for the actual relative installation paths.
4573 [Ralf S. Engelschall] PR#2175
4575 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
4577 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
4580 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
4581 Additionally the checks for finding the vendor DSO library were moved
4582 from mod_so.c to Configure because first it needs $PLAT etc. and second
4583 mod_so already uses an abstraction layer and does not fiddle with the
4584 vendor functions itself.
4585 [Jens-Uwe Mager, Ralf S. Engelschall]
4587 *) PORT: Some optimization defines for NetBSD
4588 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
4590 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
4591 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
4593 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
4594 AIX variants should work fine, too. Even AIX 3.x should work). This is
4595 accomplished by using the free DSO emulation code from Jens-Uwe Mager
4596 which we put into a os/unix/os-dso-aix.c file.
4597 [Ralf S. Engelschall]
4599 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
4600 that we should use NET_SIZE_T == int but the include files force size_t.
4601 [Ralf S. Engelschall]
4603 *) Fix two bugs in select() handling in http_main.c.
4606 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
4607 is unset (as it is in situations like timeouts) where it is unclear
4608 whether errno is set or not. [Martin Kraemer]
4610 *) Just having APACI's localstatedir is too general and not enough for most
4611 of the systems. 1.3b6 again required manual APACI patches by package
4612 maintainers from RedHat and FreeBSD because for their filesystem layout a
4613 little bit more flexibility in configuring the paths is needed. Hence we
4614 provide three additional configure options (--runtimedir, --logfiledir,
4615 --proxycachedir) which now can be used for more granular adjustments if
4616 --localstatedir is not enough to fit the particular needs. As a nice
4617 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
4618 [Ralf S. Engelschall]
4620 *) Make the install root for "make install" in APACI's Makefile overrideable
4621 by package authors. This way we are even more friendly to package
4622 maintainers (especially Debian and RedHat) who build for the real prefix
4623 via "configure --prefix=/<real>" but use a different local prefix via
4624 "make root=/tmp/apache install" for rolling the package without bristling
4625 the target location on their system.
4626 [Ralf S. Engelschall]
4628 *) Workaround sed limitations in APACI's configure script by now
4629 substituting in chunks of 50 commands (because for instance HPUX's vendor
4630 sed has a limit of max. 98 commands)
4631 [Ralf S. Engelschall] PR#2136
4633 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
4634 [Ralf S. Engelschall] PR#2140
4636 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
4637 RENAMING process because they are defined as pre-processor macros instead
4638 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
4639 [Ralf S. Engelschall]
4641 *) Workaround braindead AWK's when generating ap_config.h: The split() and
4642 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
4643 [Ralf S. Engelschall] PR#2139
4645 *) Various bugfixes and cleanups for the APACI configure script:
4646 o fix IFS handling for _nested_ situation
4647 o fix Perl interpreter search: take first one found instead of last one
4648 o fix DSO consistency check
4649 o print error messages to stderr instead of stdout
4650 o add install-quiet for --shadow situation to Makefile stub
4651 o reduce complexity by avoiding sed-hacks for rule and module list loops
4652 [Ralf S. Engelschall]
4654 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
4656 *) Make sure the input field separator (IFS) shell variable is explicitly
4657 initialized correctly before _every_ `for' loop and also restored after
4658 the loops. [Ralf S. Engelschall]
4660 *) Make sure that "make install" doesn't overwrite the `mime.types' and
4661 `magic' files from an existing Apache installation. Because people often
4662 customize these for own MIME and content types.
4663 [Ralf S. Engelschall]
4665 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
4666 [Peter Galbavy, Ralf S. Engelschall] PR#2109
4668 *) Fix the path to the ScoreBoardFile in the install-config target, too.
4669 [Ralf S. Engelschall] PR#2105
4671 *) Let "configure" clear out the users parameters (provided as shell
4672 variables) to avoid side-effects in "src/Configure" when the user
4673 exported them (which is not needed, but some users do it).
4674 [Ralf S. Engelschall] PR#2101
4676 *) Provide backward compatibility from some old src/Configuration.tmpl
4677 parameter names to the canonical Autoconf-style shell variable names. For
4678 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
4679 but a hint message is displayed. [Ralf S. Engelschall]

4682 CGI scripts from an existing Apache installation.
4683 [Ralf S. Engelschall, Jim Jagielski] PR#2084
4685 *) Make `configure --compat' more "compatible" by first
4686 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
4687 second by making sure the "avoid-bristling-suffix" /apache is not
4688 appended to sysconfdir, datadir, localstatedir and includedir when
4689 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]

4697 *) Fix the path to the MimeMagicFile in the install-config target, too.
4698 [Ralf S. Engelschall] PR#2089
4700 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
4702 *) If you start apache with the -S command line option it will dump
4703 out the parsed vhost settings. This is useful for folks trying
4704 to figure out what is wrong with their vhost configuration.
4705 (Other dumps may be added in the future.) [Dean Gaudet]
4707 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
4708 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
4711 *) Because /usr/local/apache is the default prefix the ``configure
4712 --compat'' option no longer has to set prefix, again. This way the
4713 --compat option honors a leading --prefix option. [Lars Eilebrecht]
4715 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
4716 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
4717 to avoid "discard const" warnings. [Ralf S. Engelschall]
4719 *) If a specific handler is set for a file yet the request still
4720 ends up being handled by the default handler, log an error
4721 message before handling it. This catches things such as trying
4722 to use SSIs without mod_include enabled. [Marc Slemko]
4724 *) Fix error logging for the startup case where ap_log_error() still uses
4725 stderr as the target. Now the default log level is honored here, too.
4726 [Ralf S. Engelschall]
4728 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
4729 long" errors when generating the MODULES entry for src/Makefile
4730 [Ben Hyde, Ralf S. Engelschall]
4732 *) Make sure src/Configure doesn't complain about the old directory
4733 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
4735 Changes with Apache 1.3b6
4737 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
4739 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
4740 interface via the similar but proprietary HP/UX shl_xxx-style system
4741 calls. [Ralf S. Engelschall]
4743 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
4744 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
4745 Make. [Ralf S. Engelschall]
4747 *) ++++ THE BIG SYMBOL RENAMING ++++
4748 To avoid symbol clashes with third-party code compiled into the server,
4749 we globally applied the prefix "ap_" to the following classes of
4751 - Apache provided general functions (e.g., ap_cpystrn)
4752 - Public API functions (e.g., palloc, bgets)
4753 - Private functions which we can't make static (because of
4754 cross-object usage) but should be (e.g., new_connection)
4755 For backward source compatibility a new header file named compat.h was
4756 created which provides defines for the old symbol names and can be used
4757 by third-party module authors.
4760 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
4761 problem under SVR4 is that there is no command flag to force the linker
4762 to export the global symbols of the httpd executable therewith they are
4763 available to the DSO's. Instead of problematic hacks like creating a
4764 dummy.so file (containing dummy references to all global symbols) the
4765 httpd binary is linked against, we use a clean trick stolen from Perl 5:
4766 Placing the Apache core code itself into a DSO library named libhttpd.so.
4767 This way the global symbols _HAVE_ to be exported and thus are available
4768 to any manually loaded DSO's under runtime. To reduce the impact to the
4769 user to null we go even further and create a stub httpd executable which
4770 automatically keeps track of the DSO library loading itself and thus
4771 hides the complete mechanism from the user. Although the generation of
4772 this DSO library is automatically triggered for platforms which
4773 essentially need it (mostly all SVR4-derivates) it can be also enabled
4774 manually via the Rule SHARED_CORE. This can be interesting in the future
4775 where we perhaps exploit this libhttpd.so mechanism for providing nifty
4776 features like graceful upgrades, or whatever.
4777 [Ralf S. Engelschall, Martin Kraemer]
4779 *) Build the libraries before building the rest of the tools. [Ben Hyde]
4781 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
4782 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
4783 conventions while "clean" removes only stuff created by "all" targets,
4784 "distclean" additionally removes the stuff from the configuration
4785 process. This way "make distclean" (hence the name) provides a fresh
4786 source tree as it was for distribution.
4787 [Ralf S. Engelschall]
4789 *) Allow top-level (APACI) Makefile to break on build errors
4790 the same way the src/ subtree Makefiles breaks on them by replacing the
4791 initial APACI sed-subdir-display-kludge with a more clean
4792 variable-passing-solution: variable SDP can optionally hold the subdir
4793 prefix which is consistently used for displaying the subdir movement.
4794 This way even the top-level Makefile can stop correctly on errors as the
4795 user expects. [Ralf S. Engelschall]
4797 *) Fixed ordering of argument checks for RewriteBase directive.
4798 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
4800 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
4801 indicating that a module is being compiled for dynamic loading. Also
4802 remove #define IS_MODULE from modules and add SHARED_MODULE define
4803 to the mak/dsp files. [Alexei Kosut]
4805 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
4806 since we are now logging APLOG_WARNING by default. [Roy Fielding]
4808 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
4810 *) Add documentation file and src/Configuration.tmpl entry for the
4811 experimental mod_mmap_static module. Because although it is and marked as
4812 an experimental one it is distributed and thus should be documented and
4813 prepared for configuration the same way as all others modules.
4814 [Ralf S. Engelschall]
4816 *) Add query (-q) option to apxs support tool to be able to manually query
4817 specific settings from apxs. This is needed for instance when you
4818 manually want to access Apache's header files and you need to assemble
4819 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
4820 [Ralf S. Engelschall]
4822 *) Now src/Configure uses a fallback strategy for the shared object support
4823 on platforms where no explicit information is available: If a Perl
4824 installation exists we ask it about its shared object support and if it's
4825 the dlopen-style one we shamelessly guess the compiler and linker flags
4826 for creating shared objects from Perls knowledge. Of course, the user is
4827 warning about what we are doing and informed that he should send us
4828 the guessed flags when they work. [Ralf S. Engelschall]
4830 *) Provide APACI --without-support option to be able to disable the build
4831 and installation of the support tools from the src/support/ area.
4832 Although its useful to have these installed per default we should provide
4833 a way to compile and install without them for backward-compatibility.
4834 [Ralf S. Engelschall]
4836 *) Add of the new APache eXtenSion (apxs) support tool for building and
4837 installing modules into an _already installed_ Apache package through the
4838 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
4839 this approach actually doesn't need the Apache source tree. The
4840 (APACI-installed) server package is enough, because this now includes the
4841 Apache C header files (PREFIX/include) and the new APXS tool
4842 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
4843 module authors to build their Apache modules _OUTSIDE_ the Apache source
4844 tree while avoiding them to fiddle around with the totally platform
4845 dependend way of compiling DSO files. The tool supports all ranges of
4846 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
4847 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
4848 on-the-fly generate a minimalistic Makefile and sample module for the
4849 first step to provide both a quick success event and to demonstrate the
4850 APXS mechanism to module authors. [Ralf S. Engelschall]
4852 *) Fix core dumps in use of CONNECT in proxy.
4853 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
4855 *) Modify the log directives in httpd.conf-dist files to use CustomLog
4856 so that users have examples of how CustomLog can be used.
4859 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
4860 the Apache distribution tree. Until Apache 1.3 there was no real
4861 out-of-the-box batch-capable build and installation procedure for the
4862 complete Apache package. This is now provided by a top-level "configure"
4863 script and a corresponding top-level "Makefile.tmpl" file. The goal is
4864 to provide a GNU Autoconf-style frontend which is capable to both drive
4865 the old src/Configure stuff in batch and additionally installs the
4866 package with a GNU-conforming directory layout. Any options from the old
4867 configuration scheme are available plus a lot of new options for flexibly
4868 customizing Apache. [Ralf S. Engelschall]
4870 *) The floating point ap_snprintf code wasn't threadsafe.
4871 Had to remove the HAVE_CVT macro in order to do threadsafe
4872 calling of the ?cvt() floating point routines. [Dean Gaudet]
4874 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
4876 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
4877 [Jim Jagielski] PR#1901
4879 *) BUG: Configure was using TCC and CC inconsistently. Make sure
4880 Configure knows which CC we are using. [Jim Jagielski]
4882 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
4883 was defined in a parent directory. [Lars Eilebrecht]
4885 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
4886 a generic printf-style routine that can call arbitrary output
4887 routines. Use this to replace http_bprintf.c. Add new routines
4888 psprintf(), pvsprintf() which allocate the exact amount of memory
4889 required for a string from a pool. Use psprintf() to clean up
4890 various bits of code which used ap_snprintf()/pstrdup().
4893 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
4894 ap_snprintf() has different semantics and formatting codes than
4895 snprintf(). [Dean Gaudet]
4897 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
4898 is necessary on at least Solaris where the /etc/rc?.d scripts
4899 are run with these signals ignored, and "SIG_IGN" settings are
4900 maintained across exec().
4901 [Rein Tollevik <reint@sys.sol.no>] PR#2009
4903 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
4904 used instead of lstat() and thus this flag didn't work as expected.
4905 [Rein Tollevik <reint@sys.sol.no>] PR#2010
4907 *) Fix the proxy pass-through feature of mod_rewrite for the case of
4908 existing QUERY_STRING now that mod_proxy was recently changed because of
4909 the new URL parsing stuff. [Ralf S. Engelschall]
4911 *) A few changes to scoreboard definitions which helps gcc generate
4912 better code. [Dean Gaudet]
4914 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
4915 be a signed bitfield. So mark a few bitfields as signed to
4916 ensure correct code. [Dean Gaudet]
4918 *) The default for HostnameLookups was changed to Off, but there
4919 was a problem and it wasn't taking effect. [Dean Gaudet]
4921 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
4924 *) After a SIGHUP the listening sockets in the parent weren't
4925 properly marked for closure on fork().
4926 [Jürgen Keil <jk@tools.de>] PR#2000
4928 *) Allow %2F in two situations: 1) it is in the query part of the URI,
4929 therefore not exposed to %2F -> '/' translations and 2) the request
4930 is a proxy request, so we're not dealing with a local resource anyway.
4931 Without this, the proxy would fail to work for any URL's with
4932 %2f in them (occurs quite often in
4933 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
4935 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
4937 *) Make the shared object compilation command more portable by avoiding
4938 the direct combination of `-c' & `-o' which is not honored by some
4939 compilers like UnixWare's cc. [Ralf S. Engelschall]
4941 *) WIN32: the proxy was creating filenames missing the last four
4942 characters. While this normally doesn't stop anything from
4943 working, it can result in extra collisions.
4944 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
4946 *) Now mod_proxy uses the response string (in addition to the response status
4947 code) from the already used FTP SIZE command to setup the Content-Length
4948 header if available. [Ralf S. Engelschall] PR#1183
4950 *) Reanimated the (still undocumented) proxy receive buffer size directive:
4951 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
4952 name was really too generic, added documentation for this directive to
4953 the mod_proxy.html and corrected the hyperlink to it in the
4954 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
4956 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
4957 faster [Martin Kraemer]
4959 *) Make Configure die when you give it an unknown command switch.
4962 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
4963 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
4964 and per default compiled support programs have manual pages - just to
4965 document our stuff a little bit more and to be able to do really
4966 Unix-like installations ;-) [Ralf S. Engelschall]
4968 *) Major cleanups to the Configure script to make it and its generated
4969 Makefiles again readable and maintainable: add SRCDIR option, removed
4970 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
4971 generated sections, consequently added Makefile headers with inheritance
4972 information, added subdir movement messages for easier following where
4973 the build process currently stays (more verbose then standard Make, less
4974 verbose than GNU make), same style to comments in the Configure script,
4975 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
4977 *) Add the new ApacheBench program "ab" to src/support/: This is derived
4978 from the ZeusBench benchmarking program and can be used to determine the
4979 response performance of an Apache installation. This version is
4980 officially licensed with Zeus Technology, Ltd. See the license agreement
4981 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
4982 [Ralf S. Engelschall]
4984 *) API: Various core functions that are definately not part of the API
4985 have been made static, and a few have been marked API_EXPORT. Still
4986 more have been marked CORE_EXPORT and are not intended for general
4987 use by modules. [Doug MacEachern, Dean Gaudet]
4989 *) mod_proxy was not clearing the Proxy-Connection header from
4990 requests; now it does. This did not violate any spec, however
4991 causes poor interactions when you are talking to remote proxies.
4992 [Marc Slemko] PR#1741
4994 *) Various cleanups to the command line interface and manual pages.
4995 [Ralf S. Engelschall]
4997 *) cfg_getline() was not properly handling lines that did not end
4998 with a line termination character. [Marc Slemko] PR#1869, 1909
5000 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
5002 *) Clean up some undocumented behavior of mod_setenvif related to
5003 "merging" two SetEnvIf directives when they match the same header
5004 and regex. Document that mod_setenvif will perform comparisons in
5005 the order they appear in the config file. Optimize mod_setenvif by
5006 doing more work at config time rather than at runtime.
5009 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
5010 to allow for modules to overrule them and to reduce redefinition
5011 warnings [Jim Jagielski]
5013 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
5016 *) Making the hard-coded cross-module function call mime_find_ct() (from
5017 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
5018 checking is really called even for proxy requests except for URLs with
5019 HTTP schemes (because there we can optimize by not running the type
5020 checking hooks due to the fact that the proxy gets the MIME Content-type
5021 from the remote host later). This change cleans up mod_mime by removing
5022 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
5023 especially unbundles mod_proxy and mod_mime. This way they both now can
5024 be compiled as shared objects and are no longer tied together.
5025 [Ralf S. Engelschall]
5027 *) util.c cleanup and speedup. [Dean Gaudet]
5029 *) API: Clarification, pstrndup() will always copy n bytes of the source
5030 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
5032 *) Mark module command_rec and handler_rec structures const so that they
5033 end up in the read-only data section (and are friendlier to systems
5034 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
5036 *) Add check to the "Port" directive to make sure the specified
5037 port is in the appropriate range. [Ben Hyde]
5039 *) Performance improvements to invoke_handler().
5040 [Dmitry Khrustalev <dima@bog.msu.su>]
5042 *) Added support for building shared objects even for library-style modules
5043 (which are built from more than one object file). This now provides the
5044 ability to build mod_proxy as a shared object module. Additionally
5045 modules like mod_example are now also supported for shared object
5046 building because the generated Makefiles now no longer assume there is at
5047 least one statically linked module. [Ralf S. Engelschall]
5049 *) API: Clarify usage of content_type, handler, content_encoding,
5050 content_language and content_languages fields in request_rec. They
5051 must always be lowercased; and the strings pointed to shouldn't
5052 be modified (you must copy them to modify them). Fix a few bugs
5053 related to this. [Dean Gaudet]
5055 *) API: Clarification: except for RAW_ARGS, all command handlers can
5056 treat the char * parameters as permanent, and modifiable. There
5057 is no need to pstrdup() them. Clean up some needless pstrdup().
5060 *) Now mod_so keeps track of which module shared objects with which names
5061 are loaded and thus avoids multiple loading and unloading and irritating
5062 error_log messages. [Ralf S. Engelschall]
5064 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
5065 environment variable in the apache core. But that tweaking interferes
5066 with mod_setenv. So don't tweak if the user has specified an explicit
5067 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
5069 *) rputs() did not calculate r->sent_bodyct properly.
5070 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
5072 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
5073 name, or left unset if this value is unavailable. Apache was setting
5074 it to the IP address when unavailable.
5075 [Tony Finch <fanf@demon.net>] PR#1925
5077 *) Various improvements to the configuration and build support for compiling
5078 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
5079 OSF1 support with GCC and vendor compilers was added. This way shared
5080 object support is now provided out-of-the-box for FreeBSD, Linux,
5081 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
5082 [Ralf S. Engelschall]
5084 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
5085 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
5086 and USE_OS2_SCOREBOARD. [Dean Gaudet]
5088 *) Fix one more special locking problem for RewriteMap programs in
5089 mod_rewrite: According to the documentation of flock(), "Locks are on
5090 files, not file descriptors. That is, file descriptors duplicated
5091 through dup(2) or fork(2) do not result in multiple instances of a lock,
5092 but rather multiple references to a single lock. If a process holding a
5093 lock on a file forks and the child explicitly unlocks the file, the
5094 parent will lose its lock.". To overcome this we have to make sure the
5095 RewriteLock file is opened _AFTER_ the childs were spawned which is now
5096 the case by opening it in the child_init instead of the module_init API
5097 hook. [Ralf S. Engelschall] PR#1029
5099 *) Change to Location and LocationMatch semantics. LocationMatch no
5100 longer lets a single slash match multiple adjacent slashes in the
5101 URL. This change is for consistency with RewriteRule and
5102 AliasMatch. Multiple slashes have meaning in URLs that they do
5103 not have in (some) filesystems. Location on the other hand can
5104 be considered a shorthand for a more complicated regex, and it
5105 does match multiple slashes with a single slash -- which is
5106 also consistent with the Alias directive.
5107 [Dean Gaudet] related PR#1440
5109 *) Fix bug with mod_mime_magic causing certain files, including files
5110 of length 0, to result in no response from the server.
5113 *) The Configure script now generates src/include/ap_config.h which
5114 contains the set of defines used when Apache is compiled on a platform.
5115 This file can then be included by external modules before including
5116 any Apache header files in case they are being built separately from
5117 Apache. Along with this change, a couple of minor changes were
5118 made to make Apache's #defines coexist peacefully with any autoconf
5119 defines an external module might have. [Rasmus Lerdorf]
5121 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
5122 but without any RewriteXXXXX directives. Here mod_rewrite is given no
5123 chance by the API to initialize its per-server configuration and thus
5124 receives the wrong one from the main server. This is now avoided by
5125 remembering the server together with the config structure while
5126 configuring and later assuming there is no config when we see a
5127 difference between the remembered server and the one calling us.
5128 [Ralf S. Engelschall] PR#1790
5130 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
5131 is automatically disabled under configure time when the dbm_xxx functions
5132 are not available. Second, two heavy source code errors in the DBM
5133 support code were fixed. This makes DBM RewriteMap's usable again after
5134 a long time of brokenness. [Ralf S. Engelschall] PR#1696
5136 *) Now all configuration files support Unix-style line-continuation via
5137 the trailing backslash ("\") character. This enables us to write down
5138 complex or just very long directives in a more readable way. The
5139 backslash character has to be really the last character before the
5140 newline and it has not been prefixed by another (escaping) backslash.

5146 *) To deal with modules being compiled and [dynamically] linked
5147 at a different time from the core, the SERVER_VERSION and
5148 SERVER_BUILT symbols have been abstracted through the new
5149 API routines apapi_get_server_version() and apapi_get_server_built().
5152 *) WIN32: Preserve trailing slash in canonical path (and hence
5153 in PATH_INFO). [Paul Sutton, Ben Laurie]
5155 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
5156 depending on the rev of Solaris and what mixture of modules
5157 are in use. So it has been disabled, and Solaris is back to
5158 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
5159 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
5160 up static content only servers. Or it may fail unpredictably.

5163 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
5166 *) API: Rewrite of absoluteURI handling, and in particular how
5167 absoluteURIs match vhosts. Unless a request is a proxy request, a
5168 "http://host" url is treated as if a similar "Host:" header had been
5169 supplied. This change was made to support future HTTP/1.x protocols
5170 which may require clients to send absoluteURIs for all requests.
5172 In order to achieve this change subtle changes were made to the API. In a
5173 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
5174 that the unmodified uri can be retrieved easily. r->proxyreq is not set
5175 by the core, modules must set it during the post_read_request or
5176 translate_names phase.
5178 Plus changes to the virtualhost test suite for absoluteURI testing.
5180 This fixes several bugs with the proxy proxying requests to vhosts
5181 managed by the same httpd.
5184 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
5185 code from mod_rewrite. The vhost matching is now performed by a
5186 globally available function matches_request_vhost(). [Dean Gaudet]

5202 *) API: A new source module main/util_uri.c; It contains a routine
5203 parse_uri_components() and friends which breaks a URI into its component
5204 parts. These parts are stored in a uri_components structure called
5205 parsed_uri within each request_rec, and are available to all modules.
5206 Additionally, an unparse routine is supplied which re-assembles the URI
5207 components back to an URI, optionally hiding the username:password@ part
5208 from ftp proxy requests, and other useful routines. Within the structure,
5209 you find on a ready-for-use basis:
5210 scheme; /* scheme ("http"/"ftp"/...) */
5211 hostinfo; /* combined [user[:password]@]host[:port] */
5212 user; /* user name, as in http://user:passwd@host:port/ */
5213 password; /* password, as in http://user:passwd@host:port/ */
5214 hostname; /* hostname from URI (or from Host: header) */
5215 port_str; /* port string (integer representation is in "port") */
5216 path; /* the request path (or "/" if only scheme://host was given) */
5217 query; /* Everything after a '?' in the path, if present */
5218 fragment; /* Trailing "#fragment" string, if present */
5219 This is meant to serve as the platform for *BIG* savings in
5220 code complexity for the proxy module (and maybe the vhost logic).
5223 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
5224 ${map:key}) available for all location where a string is created in
5225 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
5226 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
5227 possible expansions are consequently usable at all string creation
5228 locations. [Ralf S. Engelschall]
5230 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
5231 and not 1) and the per-virtual-server merging of directives. Now all
5232 directives except `RewriteEngine' and `RewriteOption' are either
5233 completely overridden (default) or completely inherited (when
5234 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

5243 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
5244 (like SunOS and FreeBSD) which don't accept the locking of pipes
5245 directly. A new directive RewriteLock is introduced which can be used to
5246 setup a separate locking file which then is used for synchronization.

5264 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
5265 type but with a special post-processing for the looked-up value: It
5266 parses it into alternatives according to `|' chars and then only one
5267 particular alternative is chosen randomly (this is an essential
5268 functionality needed for balancing between backend-servers when using
5269 Apache as a Reverse Proxy. The looked up value here is a list of
5270 servers). Second, `int' with the built-in maps named `tolower' and
5271 `toupper' which can be used to map URL parts to a fixed case (this is an
5272 essential feature to fix the case of server names when doing mass
5273 virtual-hosting with the help of mod_rewrite instead of using
5274 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
5275 Jay Soffian <jay@cimedia.com>] PR#1631
5277 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
5278 This directive lets Apache adjust the URL in Location-headers on HTTP
5279 redirect responses sent by the remote server. This way the virtually
5280 mapped area is no longer left on redirects and thus by-passed which is
5281 especially essential when running Apache as a reverse proxy.

5299 *) Use SA_RESETHAND or SA_ONESHOT when installing the coredump handlers.

5382 Changes with Apache 1.3b4
5384 *) The module structure was modified to include a *dynamic_load_handle

5386 has been bumped accordingly. [Paul Sutton]
5388 *) All BrowserMatch directives mentioned in
5389 htdocs/manual/known_client_problems.html are in the default
5390 configuration files. [Lars Eilebrecht]
5392 *) MiNT port update. [Jan Paul Schmidt]
5394 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
5395 equivalent, similarly for x-compress and compress. Apache
5396 now ignores a leading x- when comparing encodings. It also
5397 preserves the encoding the client requests (for example if
5398 it requests x-gzip, then Apache will respond with x-gzip
5399 in the Content-Encoding header).
5400 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1772
5402 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
5404 *) Added mod_so module to support dynamic loading of modules on Unix
5405 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
5406 instead of AddModule in Configuration to build shared modules

5409 *) Minor cleanups to r->finfo handling in some modules.
5412 *) Abstract read()/write() to ap_read()/ap_write().
5413 Makes it easier to add other types of IO code such as SFIO.
5416 *) API: Generalize default_port manipulations to make support of
5417 different protocols easier. [Ben Laurie, Randy Terbush]
5419 *) There are many cases where users do not want Apache to form
5420 self-referential urls using the "canonical" ServerName and Port.
5421 The new UseCanonicalName directive (default on), if set to off
5422 will cause Apache to use the client-supplied hostname and port.
5423 API: Part of this change required a change to the construct_url()
5424 prototype; and the addition of get_server_name() and

5427 PR#315, 459, 485, 1433
5429 *) Yet another rearrangement of the source tree.. now all the common
5430 header files are in the src/include directory. The -Imain -Iap
5431 references in Makefiles have been changed to the simpler -Iinclude
5432 instead. In addition to simplifying the build a little bit, this
5433 also makes it clear when a module is referencing something in a
5434 other than kosher manner (e.g., the proxy including mod_mime.h).
5435 Module-private header files (the proxy, mod_mime, the regex library,
5436 and mod_rewrite) have not been moved to src/include; nor have
5437 the OS-abstraction files. [Ken Coar]
5439 *) Fix a bug where r->hostname didn't have the :port stripped
5440 from it. [Dean Gaudet]
5442 *) Tweaked the headers_out table size, and the subprocess_env
5443 table size guess in rename_original_environment(). Added
5444 MAKE_TABLE_PROFILE which can help discover make_table()
5445 calls that use too small an initial guess, see alloc.c.
5448 *) Options and AllowOverride weren't properly merging in the main
5449 server setting inside vhosts (only an issue when you have no
5450 <Directory> or other section containing an Options that affects
5451 a request). Options +foo or -foo in the main_server wouldn't
5452 affect the main_server's lookup defaults. [Dean Gaudet]
5454 *) Variable 'cwd' was being used pointlessly before being set.
5457 *) r->allowed handling cleaned up in the standard modules.
5460 *) Some case-sensitivity issues cleaned up to be consistent with
5461 RFC2068. [Dean Gaudet]
5463 *) SIGURG doesn't exist everywhere.
5464 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
5466 *) mod_unique_id was erroneously generating a second unique id when
5467 an internal redirect occured. Such redirects occur, for example,
5468 when processing a DirectoryIndex match. [Dean Gaudet]
5470 *) API: table_add, table_merge, and table_set include implicit pstrdup()
5471 of the key and value. But in many cases this is not required
5472 because the key/value is a constant, or the value has been built
5473 by pstrcat() or other similar means. New routines table_addn,
5474 table_mergen, and table_setn have been added to the API, these
5475 routines do not pstrdup() their arguments. The core code and
5476 standard modules were changed to take advantage of these routines.
5477 The resulting server is up to 20% faster in some situations.
5479 Note that it is easy to get code subtly wrong if you pass a key/value
5480 which is in a pool other than the pool of the table. The only
5481 safe thing to do is to pass key/values which are in the pool of
5482 the table, or in one of the ancestors of the pool of the table.
5483 i.e. if the table is part of a subrequest, a value from the main
5484 request's pool is OK since the subrequest pool is a sub_pool of the
5485 main request's pool (and therefore has a lifespan at most as long as
5486 the main pool). There is debugging code which can detect improper
5487 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
5488 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
5490 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
5491 which don't exist on disk more gracefully; handles vhosts properly.
5492 Update documentation to reflect the code -- if there's no
5493 MimeMagicFile directive then the module is not enabled.
5496 *) PORT: Some older *nix dialects cannot automatically start scripts
5497 which begin with a #! interpreter line (the shell starts the scripts
5498 appropriately on these platforms). Apache now supports starting of
5499 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
5500 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
5503 *) API: "typedef array_header table" removed from alloc.h, folks should
5504 have been writing to use table as if it were an opaque type, but even
5505 some standard modules got this wrong. By changing the definition
5506 to "typedef struct table table" module authors will receive compile
5507 time warnings that they're doing the wrong thing. This change
5508 facilitates future changes with more sophisticated table
5509 structures. Specifically, module authors should be using table_elts()
5510 to get access to an array_header * for the table. [Dean Gaudet]
5512 *) API: Renamed new_connection() to avoid namespace collision with LDAP
5513 library routines. [Ken Coar, Rasmus Lerdorf]
5515 *) WIN32: mod_speling is now available on the Win32 platform.
5518 *) For clarity the following compile time definition was changed:
5520 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
5522 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
5523 and not be a general notice that the OS has mmap(). Now the
5524 HAVE_MMAP/SHMGET #defines strictly are informational that the
5525 OS has that method of shared memory; the type to use for
5526 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
5527 and USE_SHMGET_SCOREBOARD). This allows outside modules to
5528 determine if shared memory is available and allows Apache
5529 to determine the best method to use for the scoreboard.
5532 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
5533 as do various earlier versions. It should be safe on all versions.
5534 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
5535 the slack code. A few other cleanups for Unixware.

5541 *) When die() happens we need to eat any request body if one exists.
5542 Otherwise we can't continue with a keepalive session. This shows up
5543 as a POST problem with MSIE 4.0, typically against pages which are
5544 authenticated. [Roy Fielding] PR#1399
5546 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization

5557 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
5558 The choice of flock vs. fcntl was made based on timings which showed that
5559 even on non-NFS, non-exported filesystems fcntl() was an order of
5560 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
5561 that single socket users will see no difference. [Dean Gaudet] PR#467
5563 *) "File does not exist" error message was erroneously including the
5564 errno. [Marc Slemko]
5566 *) Improve the warning message generated when a client drops the

5571 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
5573 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.

5583 *) Some const declarations in mod_imap.c that were added for debugging
5584 purposes caused some compilers heartburn without adding any
5585 significant value, so they've been removed. [Ken Coar]
5587 *) The src/main/*.h header files have had #ifndef wrappers added to
5588 insulate them against duplicate calls if they get included through
5589 multiple paths (e.g., in .c files as well as other .h files).
5592 *) The libap routines now have a header file for their prototypes,
5593 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
5595 *) mod_autoindex with a plaintext header file would emit the <PRE>
5596 start-tag before the HTML preamble, rather than after the preamble
5597 but before the header file contents. [John Van Essen <jve@gamers.org>]
5600 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
5601 only an issue on systems without a MAXDNAME define or where
5602 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
5604 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
5605 is used to read various types of files such as htaccess and
5606 htpasswd files. [Marc Slemko]
5608 *) SECURITY: Ensure that the buffer returned by ht_time is always
5609 properly null terminated. [Marc Slemko]
5611 *) The "Connection" header could be sent back with multiple "close"
5612 tokens. Not an error, but a waste.
5613 [Ronald.Tschalaer@psi.ch] PR#1683
5615 *) mod_rewrite's RewriteLog should behave like mod_log_config, it

5618 *) "basic" auth needs a case-insensitive comparison.
5619 [Ronald.Tschalaer@psi.ch] PR#1666
5621 *) For maximum portability, the environment passed to CGIs should
5622 only contain variables whose names match the regex
5623 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
5624 underscores over any character outside the regex. This
5625 affects HTTP_* variables, in a way that should be backward
5626 compatible for all the standard headers; and affects variables
5627 set with SetEnv/BrowserMatch and similar directives.

5671 (but there is as yet no way to signal this to Apache). Various
5672 other cleanups. [Paul Sutton]
5674 *) The aplog_error changes specific to 1.3 introduced a buffer
5675 overrun in the (now legacy) log_printf function. Fixed.
5678 *) mod_digest didn't properly deal with proxy authentication. It

5713 *) send_fd_length() did not calculate total_bytes_sent properly.
5714 [Ben Reser <breser@regnow.com>] PR#1366
5716 *) The bputc() macro was not properly integrated with the chunking
5717 code; in many cases modules using bputc() could cause completely
5718 bogus chunked output. (Typically this will show up as problems
5719 with Internet Explorer 4.0 reading a page, but other browsers
5720 having no problem.) [Dean Gaudet]
5722 *) Create LARGE_WRITE_THRESHOLD define which determines how many
5723 bytes have to be supplied to bwrite() before it will consider
5724 doing a writev() to assemble multiple buffers in one system
5725 call. This is critical for modules such as mod_include,
5726 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
5727 strings in some cases. The result would be extra effort
5728 setting up writev(), and in many cases extra effort building
5729 chunks. The default is 31, it can be overriden at compile

5829 can be used by items in src/support among other things.

5832 *) Give a more informative error when no AuthType is set.
5835 *) Remove strtoul() use from mod_proxy because it isn't available
5836 on all platforms. [Marc Slemko] PR#1214
5838 *) WIN32: Some Win32 systems terminated all responses after 16 kB.
5839 This turns out to be a bug in Winsock - select() doesn't always
5840 return the correct status. [Ben Laurie]
5842 *) Directives owned by http_core can now use the new check_cmd_context()
5843 routine to ensure that they're not being used within a container
5844 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
5846 *) PORT: Recent changes made it necessary to add explicit prototype
5847 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
5849 *) It was necessary to distinguish between resources which are
5850 allocated in the parent, for cleanup in the parent, and resources
5851 which are allocated in each child, for cleanup in each child.
5852 A new pool was created which is passed to the module child_init
5853 and child_exit functions; modules are free to register per-child
5854 cleanups there. This fixes a bug with reliable piped logs.
5857 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
5858 unless it was also doing FancyIndexes, but it displayed the
5859 HeaderName file at the top under all circumstances. It now shows
5860 the ReadmeName file for simple indices, too, as it should.
5863 *) http_core was mmap()ing even in cases where it wasn't going to
5864 read the file. [Ben Hyde <bhyde@gensym.com>]
5866 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
5867 Now the rewriting engine (the heart of mod_rewrite) is organized more
5868 straight-forward, first time well documented and reduced to the really
5869 essential parts. All redundant cases were stripped off and processing now
5870 is the same for both per-server and per-directory context with only a
5871 minimum difference (the prefix stripping in per-dir context). As a
5872 side-effect some subtle restrictions and two recently discovered problems
5873 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
5874 context and restrictions on the substitution URL on redirects.
5875 Additionally some minor source cleanups were done.

6030 Changes with Apache 1.3b2 (there is no 1.3b1)
6032 *) TestCompile was not passing $LIBS [Dean Gaudet]
6034 *) Makefile.tmpl was not using $CFLAGS in the link phase.
6037 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
6038 rudimentary memory debugger which can be used on live servers with
6039 low impact -- it sets all allocated and freed memory bytes to 0xa5.
6040 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
6041 and free() for each object. This is far more expensive and should
6042 only be used for testing with tools such as Electric Fence and
6043 Purify. See main/alloc.c for more details. [Dean Gaudet]
6045 *) Configure uses a sh trap and didn't set its exitcode properly.
6046 [Dean Gaudet] PR#1159
6048 *) Yet another vhost revamp. Add the NameVirtualHost directive which
6049 explicitly lists the ip:port pairs that are to be used for name-vhosts.
6050 From a given ip:port, regardless what the Host: header is, you can
6051 only reach the vhosts defined on that ip:port. The precedence of
6052 vhosts was reversed to match other precedences in the config --
6053 the earlier vhosts override the later vhosts. All vhost matching was
6054 moved into http_vhost.[ch]. [Dean Gaudet]
6056 *) ap_inline can be used to force inlining. GNUC __attribute__() can
6057 be used for whatever reason is appropriate (i.e. format() warnings
6058 for printf style functions). Both are enabled only with
6059 gcc >= 2.7.x (so that we have fewer support issues with older
6060 versions). [Dean Gaudet]
6062 *) Fix support for Proxy Authentication (we were testing the response
6063 status too early). [Marc Slemko]
6065 *) CoreDumpDirectory directive directs where the core file is
6066 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are

6070 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
6072 *) When booting, apache will now detach itself from stdin, stdout,
6073 and stderr. stderr will not be detached until after the config
6074 files have been read so you will be able to see initial error
6075 messages. After that all errors are logged in the error_log.
6076 This makes it more convenient to start apache via rsh, ssh,
6077 or crontabs. [Dean Gaudet] PR#523
6079 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
6080 Also removed the auto-generated link to www.apache.org that was the
6081 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
6083 *) send_fb would not detect aborted connections in some situations.
6086 *) mod_include would use uninitialized data when parsing certain
6087 expressions involving && and ||. [Brian Slesinsky] PR#1139
6089 *) mod_imap should only handle GET methods. [Jay Bloodworth]
6091 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
6093 *) mod_autoindex improperly counted &escapes; as more than one
6094 character in the description. It also improperly truncated
6095 descriptions that were exactly the maximum length.
6098 *) RedirectMatch was not properly escaping the result (PR#1155). Also
6099 "RedirectMatch /advertiser/(.*) $1" is now permitted.
6102 *) mod_include now uses symbolic names to check for request success
6103 and return HTTP errors, and correctly handles all types of
6104 redirections (previously it only did temporary redirect correctly).
6105 [Ken Coar, Roy Fielding]
6107 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
6108 r->filename. Since those two are meant to be in sync with each other
6109 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]

6118 reporting a select error over and over.

6121 *) Fixed error in proxy_util.c when looping through multiple host IP
6122 addresses. [Lars Eilebrecht] PR#974
6124 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
6125 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
6126 bytes before writing, but it will never split a log entry across a
6127 buffer boundary. [Dean Gaudet]
6129 *) API: the short_score record has been split into two pieces, one which
6130 the parent writes on, and one which the child writes on. As part of
6131 this change the get_scoreboard_info() function was removed, and
6132 scoreboard_image was exported. This change fixes a race condition
6133 in file based scoreboard systems, and speeds up changes involving the
6134 scoreboard in earlier 1.3 development. [Dean Gaudet]
6136 *) API: New register_other_child() API (see http_main.h) which allows
6137 modules to register children with the parent for maintenance. It
6138 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
6140 *) API: New piped_log API (see http_log.h) which implements piped logs,
6141 and will use register_other_child to implement reliable piped logs
6142 when it is available. The reliable piped logs part can be disabled
6143 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
6144 logs is only available on Unix. [Dean Gaudet]
6146 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
6147 meets_conditions(). This allows conditional HTTP selection to be
6148 handled separately from the storing of the header fields, and provides
6149 the ability for CGIs to set their own ETags for conditional checking.
6150 [Ken Coar, Roy Fielding] PR#895
6152 *) Changes to mod_log_config to allow naming of format strings.
6153 Format nicknames are defined with "LogFormat fmt nickname", and can
6154 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
6157 *) New module, "mod_speling", which can help find files even when
6158 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
6160 *) API: New function child_terminate() triggers the child process to
6161 exit, while allowing the child finish what it needs to for the
6162 current request first.
6163 [Doug MacEachern, Alexei Kosut]
6165 *) Windows now defaults to using full status reports with mod_status.
6166 [Alexei Kosut] PR #1094
6168 *) *Really* disable all mod_rewrite operations if the engine is off.
6169 Some things (like RewriteMaps) were checked/performed even if they
6170 weren't supposed to be. [Ken Coar] PR #991
6172 *) Implement a new timer scheme which eliminates the need to call alarm() all
6173 the time. Instead a counter in the scoreboard for each child is used to
6174 show when the child has made forward progress. The parent samples this
6175 counter every scoreboard maintenance cycle, and issues SIGALRM if no
6176 progress has been made in the timeout period. This reduces the static
6177 request best-case syscall count to 22 from 29. This scheme is only
6178 used by systems with memory-based scoreboards. [Dean Gaudet]
6180 *) The proxy now properly handles CONNECT requests which are sent
6181 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
6183 *) A script called apachectl has been added to the support
6184 directory. This script allows you to do things such as
6185 "apachectl start" and "apachectl restart" from the command
6188 *) Modules and core routines are now put into libraries, which
6189 simplifies the link line tremendously (among other advantages).
6192 *) Some of the MD5 names defined in Apache have been renamed to have
6193 an `ap_' prefix to avoid conflicts with routines supplied by
6194 external libraries. [Ken Coar]
6196 *) Removal of mod_auth_msql.c from the distribution. There are many
6197 other options for databases today. Rather than offer one option,
6198 offer none at this time. mod_auth_msql and other SQL database
6199 authentication modules can be found at the Apache Module Registry.
6200 http://modules.apache.org/ It would be nice to offer a generic
6201 mod_auth_sql option in the near future.
6203 *) PORT: BeOS support added [Alexei Kosut]
6205 *) Configure no longer accepts the -make option, since it creates
6206 Makefile on the fly based on Makefile.tmpl and Configuration.
6208 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
6209 of forcibly killing off all its processes and exiting without
6210 cleaning up. [Alexei Kosut]
6212 *) API: A new field in the request_rec, r->mtime, has been added to
6213 avoid gratuitous parsing of date strings. It is intended to hold
6214 the last-modified date of the resource (if applicable). An
6215 update_mtime() routine has also been added to advance it if
6216 appropriate. [Roy Fielding, Ken Coar]
6218 *) SECURITY: If a htaccess file can not be read due to bad permissions,
6219 deny access to the directory with a HTTP_FORBIDDEN. The previous
6220 behavior was to ignore the htaccess file if it could not be read.
6221 This change may make some setups with unreadable htaccess files
6222 stop working. [Marc Slemko] PR#817
6224 *) Add aplog_error() providing a mechanism to define levels of
6225 verbosity to the server error logging. This addition also provides
6226 the ability to log errors using syslogd. Error logging is configurable
6227 on a per-server basis using the LogLevel directive. Conversion
6228 of log_*() in progress. [Randy Terbush]
6230 *) Further enhance aplog_error() to not log filename, line number, and
6231 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
6233 *) WIN32: Canonicalise filenames under Win32. Short filenames are
6234 converted to long ones. Backslashes are converted to forward
6235 slashes. Case is converted to lower. Parts of URLs that do not
6236 correspond to files are left completely alone. [Ben Laurie]
6238 *) PORT: 2 new OSs added to the list of ports:
6239 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
6240 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
6242 *) Add the server version (SERVER_VERSION macro) to the "server
6243 configured and running" entry in the error_log. Also build an
6244 object file at link-time that contains the current time
6245 (SERVER_BUILT global const char[]), and include that in the
6248 *) Set r->headers_out when sending responses from the proxy.
6249 This fixes things such as the logging of headers sent from
6250 the proxy. [Marc Slemko] PR#659
6252 *) support/httpd_monitor is no longer distributed because the
6253 scoreboard should not be file based if at all possible. Use
6254 mod_status to see current server snapshot.
6256 *) (set_file_slot): New function, allowing auth directives to be
6257 independent of the server root, so the server documents can be
6258 moved to a different directory or machine more easily.
6259 [David J. MacKenzie]
6261 *) If no TransferLog is given explicitly, decline
6262 to log. This supports coexistence with other logging modules,
6263 such as the custom one that UUNET uses. [David J. MacKenzie]
6265 *) Check for titles in server-parsed HTML files.
6266 Ignore leading newlines and returns in titles. The old behavior
6267 of replacing a newline after <title> with a space causes the
6268 title to be misaligned in the listing. [David J. MacKenzie]
6270 *) Change mod_cern_meta to be configurable on a per-directory basis.
6271 [David J. MacKenzie]
6273 *) Add 'Include' directive to allow inclusion of configuration
6274 files within configuration files. [Randy Terbush]
6276 *) Proxy errors on connect() are logged to the error_log (nothing
6277 new); now they include the IP address and port that failed
6278 (*that's* new). [Ken Coar, Marc Slemko] PR#352
6280 *) Various architectures now define USE_MMAP_FILES which causes
6281 the server to use mmap() for static files. There are two
6282 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
6283 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
6284 number of bytes written in one cycle from a single mmap()d object,
6285 default 32768). [Dean Gaudet]
6287 *) API: Added post_read_request API phase which is run right after reading
6288 the request from a client, or right after an internal redirect. It is
6289 useful for modules setting environment variables that depend only on
6290 the headers/contents of the request. It does not run during subrequests
6291 because subrequests inherit pretty much everything from the main
6292 request. [Dean Gaudet]
6294 *) Added mod_unique_id which is used to generate a unique identifier for
6295 each hit, available in the environment variable UNIQUE_ID.
6298 *) init_modules is now called after the error logs have been opened. This
6299 allows modules to emit information messages into the error logs.
6302 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
6303 information for case where proxy module is not available. [Marc Slemko]
6305 *) PORT: Apache has need for mutexes to serialize its children around
6306 accept. In prior versions either fcntl file locking or flock file
6307 locking were used. The method is chosen by the definition of
6308 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
6309 and FLOCK for flock(). New options have been added:
6310 - SYSVSEM to use System V style semaphores
6311 - PTHREAD to use POSIX threads (appears to work on Solaris only)
6312 - USLOCK to use IRIX uslock
6313 Based on timing various techniques, the following changes were made
6315 - Linux 2.x uses flock instead of fcntl
6316 - Solaris 2.x uses pthreads
6317 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
6318 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
6319 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
6320 Martijn Koster <m.koster@pobox.com>]
6322 *) PORT: The semantics of accept/select make it very desirable to use
6323 mutexes to serialize accept when multiple Listens are in use. But
6324 in the case where only a single socket is open it is sometimes
6325 redundant to serialize accept(). Not all unixes do a good job with
6326 potentially dozens of children blocked on accept() on the same
6327 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
6328 the server will avoid serialization when listening on only one socket,
6329 and use serialization when listening on multiple sockets.
6330 [Dean Gaudet] PR#467
6332 *) Configure changes: TestLib replaced by TestCompile, which has
6333 some additional capability (such as doing a sanity check of
6334 the compiler and flags selected); the version of Solaris is now
6335 available via the #define value of SOLARIS2; IRIX n32bit libs
6336 now supported and selectable by new Configuration Rule: IRIXN32;
6337 We no longer default to -O2 optimization. [Jim Jagielski]
6339 *) Updated Configure: Configuration now uses AddModule to specify
6340 module source or binary file location, relative to src directory.
6341 Modules can be dropped into modules/extra, or in their own
6342 directory, and modules can come with a Makefile or Configure can
6343 create one. Modules can add compiler or library information to
6344 generated Makefiles. [Paul Sutton]
6346 *) Source core re-organisation: distributed modules are now in
6347 modules/standard. All other source code is in main. OS-specific
6348 code is in os/{unix,emx,win32} directories. [Paul Sutton]
6350 *) mod_browser has been removed, since it's replaced by mod_setenvif.
6353 *) Fix another long-standing bug in sub_req_lookup_file where it would
6354 happily skip past access checks on subdirectories looked up with
6355 relative paths. (It's used by mod_dir, mod_negotiation,
6356 and mod_include.) [Dean Gaudet]
6358 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
6359 N is the number of <Directory> sections, and M is the number of
6360 components in the filename of an object.
6362 To achieve this optimization the following config changes were made:
6363 - Wildcards (* and ?, not the regex forms) in <Directory>s,
6364 <Files>s, and <Location>s now treat a slash as a special
6365 character. For example "/home/*/public_html" previously would
6366 match "/home/a/andrew/public_html", now it only matches things
6367 like "/home/bob/public_html". This mimics /bin/sh behaviour.
6368 - It's possible now to use [] wildcarding in <Directory>, <Files>
6370 - Regex <Directory>s are applied after all non-regex <Directory>s.
6374 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
6375 and corrupted paths. [Dean Gaudet]
6377 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
6378 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
6379 be accessed now via backreferences $1..$9 in RewriteConds test-against
6380 strings in addition to RewriteRules subst string. Second the grouped
6381 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
6382 via backreferences %1..%9 both in following RewriteCond test-against
6383 strings and RewriteRules subst string. This provides maximum flexibility
6384 through the use of backreferences.
6385 Additionally the rewriting engine was cleaned up by putting common
6386 code to the new expand_backrefs_inbuffer() function.
6387 [Ralf S. Engelschall]
6389 *) When merging the main server's <Directory> and <Location> sections into
6390 a vhost, put the main server's first and the vhost's second. Otherwise
6391 the vhost can't override the main server. [Dean Gaudet] PR#717
6393 *) The <Directory> code would merge and re-merge the same section after
6394 a match was found, possibly causing problems with some modules.
6397 *) ip-based vhosts are stored and queried using a hashing function, which
6398 has been shown to improve performance on servers with many ip-vhosts.
6399 Some other changes had to be made to accommodate this:
6400 - the * address for vhosts now behaves like _default_
6401 - the matching process now is:
6402 - match an ip-vhost directly via hash (possibly matches main
6404 - if that fails, just pretend it matched the main server
6405 - if so far only the main server has been matched, perform
6406 name-based lookups (ServerName, ServerAlias, ServerPath)
6407 *only on name-based vhosts*
6408 - if they fail, look for _default_ vhosts
6409 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
6411 *) dbmmanage overhaul:
6412 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
6413 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
6414 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
6415 - provide better seed for rand
6416 - prompt for password as per getpass(3) (turn off echo, read from
6418 - use "newstyle" crypt based on $Config{osname} ($^O)
6419 - will not add a user if already in database, use new `update' command
6421 - added `check' command to check a users' password
6422 - added `import' command to convert existing password text-files or
6423 dbm files exported with `view'
6424 - more descriptive usage, general cleanup, 'use strict' clean, etc.
6427 *) Added psocket() which is a pool form of socket(), various places within
6428 the proxy weren't properly blocking alarms while registering the cleanup
6429 for its sockets. bclose() now uses pclose() and pclosesocket(). There
6430 was a bug where the client socket was being close()d twice due a still
6431 registered cleanup. [Dean Gaudet]
6433 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
6436 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
6437 [Jason Venner <jason@idiom.com>] PR#667
6439 *) Enable ``=""'' for RewriteCond directives to match against
6440 the empty string. This is the preferred way instead of ``^$''.
6441 [Ralf S. Engelschall]
6443 *) Fixed an infinite loop in mod_imap for references above the server root
6444 [Dean Gaudet] PR#748
6446 *) mod_proxy now has a ReceiveBufferSize directive, similar to
6447 SendBufferSize, so that the TCP window can be set appropriately
6448 for LFNs. [Phillip A. Prindeville]
6450 *) mod_browser has been replaced by the more general mod_setenvif
6451 (courtesy of Paul Sutton). BrowserMatch* directives are still
6452 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
6453 UnSetEnvIfZero directives. [Ken Coar]
6455 *) "HostnameLookups double" forces double-reverse DNS to succeed in
6456 order for remote_host to be set (for logging, or for the env var
6457 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
6460 *) mod_access overhaul:
6461 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
6462 and cidr syntax (i.e. 10.1.0.0/16). PR#762
6463 - Critical path was sped up by pre-computing a few things at config time.
6464 - The undocumented syntax "allow user-agents" was removed,
6465 the replacement is "allow from env=foobar" combined with mod_browser.
6466 - When used with hostnames it now forces a double-reverse lookup
6467 no matter what the directory settings are. This double-reverse
6468 doesn't affect any of the other routines that use the remote
6469 hostname. In particular it's still passed to CGIs and the log
6470 without the double-reverse check. Related PR#860.
6473 *) When a large bwrite() occurs (larger than the internal buffer size),
6474 while there is already something in the buffer, apache will combine
6475 the large write and the buffer into a single writev(). (This is
6476 in anticipation of using mmap() for reading files.)
6479 *) In obscure cases where a partial socket write occurred while chunking,
6480 Apache would omit the chunk header/footer on the next block. Cleaned
6481 up other bugs/inconsistencies in error conditions in buff.c. Fixed
6482 a bug where a long pause in DNS lookups could cause the last packet
6483 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
6485 *) API: Added child_exit function to module structure. This is called
6486 once per "heavy-weight process" just before a server child exit()'s
6487 e.g. when max_requests_per_child is reached, etc.
6488 [Doug MacEachern, Dean Gaudet]
6490 *) mod_include cleanup showed that handle_else was being used to handle
6491 endif. It didn't cause problems, but it was cleaned up too.
6494 *) mod_cern_meta would attempt to find meta files for the directory itself
6495 in some cases, but not in others. It now avoids it in all cases.
6498 *) mod_mime_magic would core dump if there was a decompression error.
6499 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
6501 *) PORT: some variants of DGUX require -lsocket -lnsl
6502 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
6504 *) mod_autoindex now allows sorting of FancyIndexed directory listings
6505 by the various fields (name, size, et cetera), either in ascending
6506 or descending order. Just click on the column header. [Ken Coar]
6508 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
6509 CPUs like the Alpha. Apache still stores ints in pointers, but that's
6510 the relatively safe direction. [Dean Gaudet] PR#344
6512 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
6513 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
6515 *) child_main avoids an unneeded call to select() when there is only one
6516 listening socket. [Dean Gaudet]
6518 *) In the event that the server is starved for idle servers it will
6519 spawn 1, then 2, then 4, ..., then 32 servers each second,
6520 doubling each second. It'll also give a warning in the errorlog
6521 since the most common reason for this is a poor StartServers
6522 setting. The define MAX_SPAWN_RATE can be used to raise/lower
6523 the maximum. [Dean Gaudet]
6525 *) Apache now provides an effectively unbuffered connection for
6526 CGI scripts. This means that data will be sent to the client
6527 as soon as the CGI pauses or stops output; previously, Apache would
6528 buffer the output up to a fixed buffer size before sending, which
6529 could result in the user viewing an empty page until the CGI finished
6530 or output a complete buffer. It is no longer necessary to use an
6531 "nph-" CGI to get unbuffered output. Given that most CGIs are written
6532 in a language that by default does buffering (e.g. perl) this
6533 shouldn't have a detrimental effect on performance.
6535 "nph-" CGIs, which formerly provided a direct socket to the client
6536 without any server post-processing, were not fully compatible with
6537 HTTP/1.1 or SSL support. As such they would have had to implement
6538 the transport details, such as encryption or chunking, in order
6539 to work properly in certain situations. Now, the only difference
6540 between nph and non-nph scripts is "non-parsed headers".
6541 [Dean Gaudet, Sameer Parekh, Roy Fielding]
6543 *) If a BUFF is switched from buffered to unbuffered reading the first
6544 bread() will return whatever remained in the buffer prior to the
6545 switch. [Dean Gaudet]
6547 Changes with Apache 1.3a1
6549 *) Added another Configure helper script: TestLib. It determines
6550 if a specified library exists. [Jim Jagielski]
6552 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
6553 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
6556 *) PORT: Some architectures use size_t for various lengths in network
6557 functions such as accept(), and getsockname(). The definition
6558 NET_SIZE_T is used to control this. [Dean Gaudet]
6560 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
6561 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
6562 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
6564 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
6565 [Igor N Kovalenko <infoh@mail.wplus.net>]
6567 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
6568 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
6569 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
6570 [Dean Gaudet] related PR#875
6572 *) API: Correct child_init() slot declaration from int to void, to
6573 match the init() declaration. Update mod_example to use the new
6576 *) added transport handle slot (t_handle) to the BUFF structure
6579 *) get_client_block() returns wrong length if policy is
6580 REQUEST_CHUNKED_DECHUNK.

6588 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
6590 *) AddModuleInfo directive for mod_info which allows you to annotate
6591 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
6593 *) Added NoProxy directive to avoid using ProxyRemote for selected
6594 addresses. Added ProxyDomain directive to cause unqualified
6595 names to be qualified by redirection.
6596 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
6598 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
6599 header to the remote host in the proxy. [Sameer Parekh and
6602 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
6603 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
6604 URLs, fixed rewritelog(), fixed forced response code handling on
6605 redirects from within .htaccess files, disabled pipe locking under
6606 braindead SunOS 4.1.x, allow env variables to be set even on rules with
6607 no substitution, bugfixed situations where HostnameLookups is off, made
6608 mod_rewrite more thread-safe for NT port and fixed problem when creating
6609 an empty query string via "xxx?".
6610 This update also removes the copyright of Ralf S. Engelschall,
6611 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
6612 exclusively copyrighted by the Apache Group now. This happened because
6613 the author now has gifted mod_rewrite exclusively to the Apache Group and
6614 no longer maintains an external version.
6615 [Ralf S. Engelschall]
6617 *) API: Added child_init function to module structure. This is called
6618 once per "heavy-weight process" before any requests are handled.
6619 See http_config.h for more details. [Dean Gaudet]
6621 *) Anonymous_LogEmail was logging on each subrequest.
6622 [Dean Gaudet] PR#421, 868
6624 *) API: Added is_initial_req() which tests if the request being
6625 processed is the initial request, or a subrequest.
6628 *) Extended SSI (mod_include) now handles additional relops for
6629 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
6631 *) Configure fixed to correctly propagate user-selected options and
6632 settings (such as CC and OPTIM) to Makefiles other than
6633 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
6635 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
6636 directory indices to start with the contents of the HeaderName file
6637 if there is one. If there isn't one, the behaviour is unchanged.
6638 [Ken Coar, Roy Fielding, Andrey A. Chernov]
6640 *) WIN32: Modules can now be dynamically loaded DLLs using the
6641 LoadModule/LoadFile directives. Note that module DLLs must be
6642 compiled with the multithreaded DLL version of the runtime library.
6643 [Alexei Kosut and Ben Laurie]
6645 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
6646 This allows the admin to completely remove automatic indexing
6647 from the server, while still supporting the basic functions of
6648 trailing-slash redirects and DirectoryIndex files. Note that if
6649 you're carrying over an old Configuration file and you use directory
6650 indexing then you'll want to add:
6652 Module autoindex_module mod_autoindex.o
6654 before mod_dir in your Configuration. [Dean Gaudet]
6656 *) popendir/pclosedir created to properly protect directory scanning.
6657 [Dean Gaudet] PR#525
6659 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
6660 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
6661 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
6664 *) The AccessFileName directive can now take more than one filename.
6665 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
6667 *) The new mod_mime_magic can be used to "magically" determine the type
6668 of a file if the extension is unknown. Based on the unix file(1)
6669 command. [Ian Kluft <ikluft@cisco.com>]
6671 *) We now determine and display the time spent processing a
6672 request if desired. [Jim Jagielski]
6674 *) mod_status: PID field of "dead" child slots no longer displays
6675 main httpd process's PID. [Jim Jagielski]
6677 *) Makefile.nt added - to build all the bits from the command line:
6678 nmake -f Makefile.nt
6679 Doesn't yet work properly. [Ben Laurie]
6681 *) Default text of 404 error is now "Not Found" rather than the
6682 potentially misleading "File Not Found". [Ken Coar]
6684 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
6685 for the net if we require people that actually need this data to
6686 enable it. [Linus Torvalds]
6688 *) directory_walk() is an expensive function, keep a little more state to
6689 avoid needless string counting. Add two new functions make_dirstr_parent
6690 and make_dirstr_prefix which replace all existing uses of make_dirstr.
6691 The new functions are a little less general than make_dirstr, but
6692 work more efficiently (less memory, less string counting).
6695 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
6696 to LDFLAGS) to avoid complications with lex rules in make files.
6697 [Dean Gaudet] PR#372
6699 *) run_method optimized to avoid needless scanning over NULLs in the
6700 module list. [Dean Gaudet]
6702 *) Revamp of (unix) scoreboard management code such that it avoids
6703 unnecessary traversals of the scoreboard on each hit. This is
6704 particularly important for high volume sites with a large
6705 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
6706 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
6707 httpd.h. [Dean Gaudet]
6709 *) In configurations using multiple Listen statements it was possible for
6710 busy sockets to starve other sockets of service. [Dean Gaudet]
6712 *) Added hook so standalone_main can be replaced at compile time
6713 (define STANDALONE_MAIN)
6716 *) Lowest-level read/write functions in buff.c will be replaced with
6717 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
6718 compile time. The default sfio discipline will behave as apache
6719 would without sfio compiled in.
6722 *) Enhance UserDir directive (mod_userdir) to accept a list of
6723 usernames for the 'disable' keyword, and add 'enable user...' to
6724 selectively *en*able userdirs if they're globally disabled.
6727 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
6728 will work with Netscape dbm files. (dbmmanage will probably not
6729 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
6731 *) Add a ListenBacklog directive to control the backlog parameter
6732 passed to listen(). Also change the default to 511 from 512.
6735 *) API: A new handler response DONE which informs apache that the
6736 request has been handled and it can finish off quickly, similar to
6737 how it handles errors. [Rob Hartill]
6739 *) Turn off chunked encoding after sending terminating chunk/footer
6740 so that we can't do it twice by accident. [Roy Fielding]
6742 *) mod_expire also issues Cache-Control: max-age headers.
6745 *) API: Added kill_only_once option for free_proc_chain so that it won't
6746 aggressively try to kill off specific children. For fastcgi.
6747 [Stanley Gambarin <gambarin@OpenMarket.com>]
6749 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
6751 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
6752 When used together, these cause mod_dir to emit HEIGHT and WIDTH
6753 attributes in the FancyIndexing IMG tags. [Ken Coar]
6755 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
6757 *) PORT: Added Windows NT support
6758 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
6760 Changes with Apache 1.2.6
6762 *) mod_include when using XBitHack Full would send ETags in addition to
6763 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
6764 [Dean Gaudet] PR#1133
6766 *) SECURITY: When a client connects to a particular port/addr, and
6767 gives a Host: header ensure that the virtual host requested can
6768 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
6770 *) Support virtual hosts with wildcard port and/or multiple ports
6771 properly. [Ed Korthof <ed@organic.com>]
6773 *) Fixed some case-sensitivity issues according to RFC2068.
6776 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
6777 and mod_include.c. [Dean Gaudet]
6779 *) Variable 'cwd' was being used pointlessly before being set.
6782 *) SIGURG doesn't exist on all platforms.
6783 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
6785 *) When an error occurs during a POST, or other operation with a
6786 request body, the body has to be read from the net before allowing
6787 a keepalive session to continue. [Roy Fielding] PR#1399
6789 *) When an error occurs in fcntl() locking suggest the user look up
6790 the docs for LockFile. [Dean Gaudet]
6792 *) table_set() and table_unset() did not deal correctly with
6793 multiple occurrences of the same key. [Stephen Scheck
6794 <sscheck@infonex.net>, Ben Laurie] PR#1604
6796 *) send_fd_length() did not calculate total_bytes_sent properly in error
6797 cases. [Ben Reser <breser@regnow.com>] PR#1366
6799 *) r->connection->user was allocated in the wrong pool causing corruption
6800 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
6802 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
6803 Also removed the auto-generated link to www.apache.org that was the
6804 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
6806 *) Multiple "close" tokens may have been set in the "Connection"
6807 header, not an error, but a waste.
6808 [Ronald.Tschalaer@psi.ch] PR#1683
6810 *) "basic" and "digest" auth tokens should be tested case-insensitive.
6811 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
6813 *) It appears the "257th byte" bug (see
6814 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
6815 at the 256th byte as well. Fixed. [Dean Gaudet]
6817 *) mod_rewrite would not handle %3f properly in some situations.
6820 *) Apache could generate improperly chunked HTTP/1.1 responses when
6821 the bputc() or rputc() functions were used by modules (such as
6822 mod_include). [Dean Gaudet]
6824 *) #ifdef wrap a few #defines in httpd.h to make life easier on
6825 some ports. [Ralf Engelschall]
6827 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
6829 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
6831 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
6833 Changes with Apache 1.2.5
6835 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
6836 only an issue on systems without a MAXDNAME define or where
6837 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
6839 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
6842 *) Fix core dump in the ftp proxy when reading incorrectly formatted
6843 directory listings. [Marc Slemko]
6845 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
6848 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
6849 is used to read various types of files such as htaccess and
6850 htpasswd files. [Marc Slemko]
6852 *) SECURITY: Ensure that the buffer returned by ht_time is always
6853 properly null terminated. [Marc Slemko]
6855 *) SECURITY: General mod_include cleanup, including fixing several
6856 possible buffer overflows and a possible infinite loop. This cleanup
6857 was done against 1.3 code and then backported to 1.2, the result
6858 is a large difference (due to indentation cleanup in 1.3 code).
6859 Users interested in seeing a smaller set of relevant differences
6860 should consider comparing against src/modules/standard/mod_include.c
6861 from the 1.3b3 release. Non-indentation changes to mod_include
6862 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
6864 *) SECURITY: Numerous changes to mod_imap in a general cleanup
6865 including fixing a possible buffer overflow. This cleanup also
6866 was done with 1.3 code as a basis, see the the previous note
6867 about mod_include. [Dean Gaudet]
6869 *) SECURITY: If a htaccess file can not be read due to bad

6910 on this platform. [Marc Slemko]
6912 Changes with Apache 1.2.3
6914 *) The request to a remote proxy was mangled if it was generated as the
6915 result of a ProxyPass directive. URL schemes other than http:// were not
6916 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,

6923 do for errors and cached responses. [Roy Fielding]
6925 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
6927 Changes with Apache 1.2.2 [not released]
6929 *) Fixed another long-standing bug in sub_req_lookup_file where it would
6930 happily skip past access checks on subdirectories looked up with relative
6931 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
6934 *) Add lockfile name to error message printed out when
6935 USE_FLOCK_SERIALIZED_ACCEPT is defined.
6938 *) Enhanced the chunking and error handling inside the buffer functions.
6939 [Dean Gaudet, Roy Fielding]
6941 *) When merging the main server's <Directory> and <Location> sections into
6942 a vhost, put the main server's first and the vhost's second. Otherwise
6943 the vhost can't override the main server. [Dean Gaudet] PR#717
6945 *) The <Directory> code would merge and re-merge the same section after
6946 a match was found, possibly causing problems with some modules.

6950 [Dean Gaudet] PR#748
6952 *) mod_include cleanup showed that handle_else was being used to handle
6953 endif. It didn't cause problems, but it was cleaned up too.
6956 *) Last official synchronization of mod_rewrite with author version (because
6957 mod_rewrite is now directly developed by the author at the Apache Group):
6958 o added diff between mod_rewrite 3.0.6+ and 3.0.9
6959 minus WIN32/NT stuff, but plus copyright removement.

6968 o remove static from local data and add static to global ones.
6969 o replaced ugly proxy finding stuff by simple
6970 find_linked_module("mod_proxy") call.

6978 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
6979 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
6980 "downgrade-1.0" which causes Apache to pretend it received a 1.0.

7001 [Dean Gaudet] PR#832
7003 *) API: In HTTP/1.1, whether or not a request message contains a body
7004 is independent of the request method and based solely on the presence
7005 of a Content-Length or Transfer-Encoding. Therefore, our default
7006 handlers need to be prepared to read a body even if they don't know
7007 what to do with it; otherwise, the body would be mistaken for the
7008 next request on a persistent connection. discard_request_body()
7009 has been added to take care of that. [Roy Fielding] PR#378
7011 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
7012 release version number, such that it always increases along the
7013 same lines as our source code branching. [Roy Fielding]

7017 Changes with Apache 1.2.1

7029 (headers, readmes, titles), mod_negotiation (type maps), or
7030 mod_cern_meta (meta files). [Dean Gaudet]
7032 *) SECURITY: Apache will refuse to run as "User root" unless
7033 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
7035 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
7036 if it contained a .htaccess disallowing symlinks. This is contrary
7037 to the rule that symlink permissions are tested with the symlink
7038 options of the parent directory. [Dean Gaudet] PR#353
7040 *) CONFIG: The LockFile directive can be used to place the serializing
7041 lockfile in any location. It previously defaulted to /usr/tmp/htlock.

7045 *) Request processing now retains state of whether or not the request
7046 body has been read, so that internal redirects and subrequests will
7047 not try to read it twice (and block). [Roy Fielding]

7059 handle high numbered descriptors (examples include bind, and
7060 solaris libc). On all systems apache attempts to keep all permanent
7061 descriptors above 15 (called the low slack line). Solaris users
7062 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
7063 which keeps all non-FILE * descriptors above 255. On all systems
7064 this should make supporting large numbers of vhosts with many open
7065 log files more feasible. If this causes trouble please report it,
7066 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
7067 [Dean Gaudet] various PRs
7069 *) Related to the last entry, network sockets are now opened before
7070 log files are opened. The only known case where this can cause
7071 problems is under Solaris with many virtualhosts and many Listen
7072 directives. But using -DHIGH_SLACK_LINE=256 described above will
7073 work around this problem. [Dean Gaudet]

7127 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
7128 reading from one buffer and writing to another, at least until it has
7129 a custom timeout handler. [Roy Fielding and Petr Lampa]
7131 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
7132 apparently due to a mismatch between sigaction and setjmp.

7139 *) Virtual hosts with the same ServerName, but on different ports, were
7140 not being selected properly. [Ed Korthof]

7144 change submitted by Jozsef Hollosi <hollosi@sbcm.com>.
7145 [Chuck Murcko] PR#614
7147 *) If multiple requests on a single connection are used to retrieve
7148 data from different virtual hosts, the virtual host list would be
7149 scanned starting with the most recently used VH instead of the first,
7150 causing most virtual hosts to be ignored.

7160 has found matching variants, but none are acceptable, return the
7161 negotiation result if there are no more DirectoryIndex names to lookup.
7162 [Petr Lampa and Roy Fielding]
7164 *) If a soft_timeout occurs after keepalive is set, then the main child
7165 loop would try to read another request even though the connection
7166 has been aborted. [Roy Fielding]
7168 *) Configure changes: Allow for whitespace at the start of a
7169 Module declaration. Also, be more understanding about the
7170 CC=/OPTIM= format in Configuration. Finally, fix compiler
7171 flags if using HP-UX's cc compiler. [Jim Jagielski]
7173 *) Subrequests and internal redirects now inherit the_request from the
7174 original request-line. [Roy Fielding]
7176 *) Test for error conditions before creating output header fields, since
7177 we don't want the error message to include those fields. Likewise,
7178 reset the content_language(s) and content_encoding of the response
7179 before generating or redirecting to an error message, since the new
7180 message will have its own Content-* definitions. [Dean Gaudet]

7183 and 304 responses) and err_headers_out (headers sent with all responses).
7184 Avoid the overhead of copying tables if err_headers_out is empty
7185 (the usual case). [Roy Fielding]

7188 not properly checking both the value configured by the DefaultType
7189 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
7190 of DEFAULT_TYPE to match the documented default (text/plain).

7196 *) Properly initialize the flock structures used by the mutex locking
7197 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
7200 *) The method for determining PATH_INFO has been restored to the pre-1.2b
7201 (and NCSA httpd) definition wherein it was the extra path info beyond
7202 the CGI script filename. The environment variable FILEPATH_INFO has
7203 been removed, and instead we supply the original REQUEST_URI to any
7204 script that wants to be Apache-specific and needs the real URI path.
7205 This solves a problem with existing scripts that use extra path info
7206 in the ScriptAlias directive to pass options to the CGI script.
7209 *) The _default_ change in 1.2b10 will change the behaviour on configs
7210 that use multiple Listen statements for listening on multiple ports.
7211 But that change is necessary to make _default_ consistent with other
7212 forms of <VirtualHost>. It requires such configs to be modified
7213 to use <VirtualHost _default_:*>. The documentation has been
7214 updated. [Dean Gaudet] PR#530
7216 *) If an ErrorDocument CGI script is used to respond to an error
7217 generated by another CGI script which has already read the message
7218 body of the request, the server would block trying to read the
7219 message body again. [Rob Hartill]

7242 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
7243 changes and in anticipation of 1.2 final release. [Roy Fielding]
7245 *) Fix problem with scripts not receiving a SIGPIPE when client drops
7246 the connection (e.g., when user presses Stop). Apache will now stop
7247 trying to send a message body immediately after an error from write.

7261 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
7262 memory allocator to avoid a behaviour that required extra blocks to

7295 then the timeout would be ignored. [Roy Fielding] PR#373
7297 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
7298 parsing of headers. If the terminating empty-line CRLF occurs starting
7299 at the 256th or 257th byte of output, then Navigator will think a normal
7300 image is invalid. We are guessing that this is because their initial
7301 read of a new request uses a 256 byte buffer. We check the bytes written
7302 so far and, if we are about to tickle the bug, we instead insert a
7303 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232

7306 of an external redirection. [Roy Fielding and Paul Sutton]

7358 Changes with Apache 1.2b8
7360 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
7361 to it. [Marc Slemko]

7371 spurious log messages, removing the nonblocking settings (they
7372 are not needed with the better timeout), and adding commentary

7400 before being reported. [Dean Gaudet]
7402 *) In the proxy, if the cache filesystem was full, garbage_coll() was
7403 never called, and thus the filesystem would remain full indefinitely.
7404 We now also remove incomplete cache files left if the origin server
7405 didn't send a Content-Length header and either the client has aborted
7406 transfer or bwrite() to client has failed. [Petr Lampa]
7408 *) Fixed the handling of module and script-added header fields.
7409 Improved the interface for sending header fields and reduced
7410 the duplication of code between sending okay responses and errors.
7411 We now always send both headers_out and err_headers_out, and
7412 ensure that the server-reserved fields are not being overridden,
7413 while not overriding those that are not reserved. [Roy Fielding]
7415 *) Moved transparent content negotiation fields to err_headers_out
7416 to reflect above changes. [Petr Lampa]
7418 *) Fixed the determination of whether or not we should make the
7419 connection persistent for all of the cases where some other part
7420 of the server has already indicated that we should not. Also
7421 improved the ordering of the test so that chunked encoding will
7422 be set whenever it is desired instead of only when KeepAlive
7423 is enabled. Added persistent connection capability for most error
7424 responses (those that do not indicate a bad input stream) when
7425 accessed by an HTTP/1.1 client. [Roy Fielding]
7427 *) Added missing timeouts for sending header fields, error responses,
7428 and the last chunk of chunked encoding, each of which could have
7429 resulted in a process being stuck in write forever. Using soft_timeout
7430 requires that the sender check for an aborted connection rather than
7431 continuing after an EINTR. Timeouts that used to be initiated before
7432 send_http_header (and never killed) are now initiated only within or
7433 around the routines that actually do the sending, and not allowed to
7434 propagate above the caller. [Roy Fielding]
7436 *) mod_auth_anon required an @ or a . in the email address, not both.
7439 *) per_dir_defaults weren't set correctly until directory_walk for
7440 name-based vhosts. This fixes an obscure bug with the wrong config
7441 info being used for vhosts that share the same ip as the server.
7444 *) Improved generation of modules/Makefile to be more generic for
7445 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
7447 *) Generate makefile dependency for Configuration based on the actual
7448 name given when running the Configure process. [Dean Gaudet]
7450 *) Fixed problem with vhost error log not being set prior to
7451 initializing virtual hosts. [Dean Gaudet]
7453 *) Fixed infinite loop when a trailing slash is included after a type map
7454 file URL (extra path info). [Petr Lampa]
7456 *) Fixed server status updating of per-connection counters. [Roy Fielding]
7458 *) Add documentation for DNS issues (reliability and security), and try
7459 to explain the virtual host matching process. [Dean Gaudet]
7461 *) Try to continue gracefully by disabling the vhost if a DNS lookup
7462 fails while parsing the configuration file. [Dean Gaudet]
7464 *) Improved calls to setsockopt. [Roy Fielding]
7466 *) Negotiation changes: Don't output empty content-type in variant list;
7467 Output charset in variant list; Return sooner from handle_multi() if
7468 no variants found; Add handling of '*' wildcard in Accept-Charset.
7469 [Petr Lampa and Paul Sutton]
7471 *) Fixed overlaying of request/sub-request notes and headers in
7472 mod_negotiation. [Dean Gaudet]
7474 *) If two variants' charset quality are equal and one is the default
7475 charset (iso-8859-1), then prefer the variant that was specifically
7476 listed in Accept-Charset instead of the default. [Petr Lampa]
7478 *) Memory allocation problem in push_array() -- it would corrupt memory
7479 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
7481 *) invoke_handler() doesn't handle mime arguments in content-type
7484 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
7487 *) Fixed problem with ErrorDocument not working for virtual hosts
7488 due to one of the performance changes in 1.2b7. [Dean Gaudet]
7490 *) Log an error message if we get a request header that is too long,
7491 since it may indicate a buffer overflow attack. [Marc Slemko]
7493 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
7494 not reject URLs without a double-slash, as per RFC2068 section 3.2.
7495 [Ken Coar] PR #146, #187
7497 *) Added table entry placeholder for new header_parser callback
7498 in all of the distributed modules. [Ken Coar] PR #191
7500 *) Allow for cgi files without the .EXE extension on them under OS/2.
7501 [Garey Smiley] PR #59
7503 *) Fixed error message when resource is not found and URL contains
7504 path info. [Petr Lampa and Dean Gaudet] PR #40
7506 *) Fixed user and server confusion over what should be a virtual host
7507 and what is the main server, resulting in access to something
7508 other than the name defined in the virtualhost directive (but
7509 with the same IP address) failing. [Dean Gaudet]
7511 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
7512 AIX; improves the redirection stuff to enable the users to generally
7513 redirect to http, https, gopher and ftp; added TIME variable for
7514 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
7515 special patterns >STRING, <STRING and =STRING to RewriteCond, which
7516 can be used in conjunction with %{TIME} or other variables to create
7517 time-dependent rewriting rules. [Ralf S. Engelschall]
7519 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
7520 Module authors may need to adjust their code for proper cleanup to take
7521 place (that is, call note_cleanups_for_fd()). This change fixes problems
7522 with file descriptors being erroneously closed when the proxy module was
7523 in use. [Ben Laurie]
7525 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
7526 initgroups() to hose the group information needed for later
7527 comparisons. [Randy Terbush]
7529 *) Remove unnecessary call to va_end() in create_argv() which
7530 caused a SEGV on some systems.
7532 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
7535 *) Clear memory allocated for listeners. [Randy Terbush]
7537 *) Improved handling of IP address as a virtualhost address and
7538 introduced "_default_" as a synonym for the default vhost config.
7539 [Dean Gaudet] PR #212
7541 Changes with Apache 1.2b7
7543 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
7545 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
7547 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
7548 - replace protocol response numbers with symbols
7549 - save variant-list into main request notes
7550 - free allocated memory from subrequests
7551 - merge notes, headers_out and err_headers_out
7553 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
7554 "HTTP/#.# ###*" to be more lenient about what we accept.
7557 *) more proxy FTP bug fixes:
7558 - Changed send_dir() to remove user/passwd from displayed URL.
7559 - Changed login error messages to be more descriptive.
7560 - remove setting of SO_DEBUG socket option
7561 - Make ftp_getrc() more lenient about multiline responses,
7562 specifically, 230 responses which don't have continuation 230-
7563 on each line). These seem to be all NT FTP servers, and while
7564 perhaps questionable, they appear to be legal by RFC 959.
7565 - Add missing kill_timeout() after transfer to user completes.
7568 *) Fixed problem where a busy server could hang when restarting
7569 after being sent a SIGHUP due to child processes not exiting.
7572 *) Modify mod_include escaping so a '\' only signifies an escaped
7573 character if the next character is one that needs
7574 escaping. [Ben Laurie]
7576 *) Eliminated possible infinite loop in mod_imap when relative URLs are
7577 used with a 'base' directive that does not have a '/' in it.
7578 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
7580 *) Reduced the default timeout from 1200 seconds to 300, and the
7581 one in the sample configfile from 400 to 300. [Marc Slemko]
7583 *) Stop vbprintf from crashing if given a NULL string pointer;
7584 print (null) instead. [Ken Coar]
7586 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
7587 [Marc Slemko and Roy Fielding]
7589 *) Fixed problem with mod_cgi-generated internal redirects trying to
7590 read the request message-body twice. [Archie Cobbs and Roy Fielding]
7592 *) Reduced timeout on lingering close, removed possibility of a blocked
7593 read causing the child to hang, and stopped logging of errors if
7594 the socket is not connected (reset by client). [Roy Fielding]
7596 *) Rearranged main child loop to remove duplication of code in
7597 select/accept and keep-alive requests, fixed several bugs regarding
7598 checking scoreboard_image for exit indication and failure to
7599 account for all success conditions and trap all error conditions,
7600 prevented multiple flushes before closing the socket; close the entire
7601 socket buffer instead of just one descriptor, prevent logging of
7602 EPROTO and ECONNABORTED on platforms where supported, and generally
7603 improved readability. [Roy Fielding]
7605 *) Extensive performance improvements. Cleaned up inefficient use of
7606 auto initializers, multiple is_matchexp calls on a static string,
7607 and excessive merging of response_code_strings. [Dean Gaudet]
7609 *) Added double-buffering to mod_include to improve performance on
7610 server-side includes. [Marc Slemko]
7612 *) Several fixes for suexec wrapper. [Randy Terbush]
7613 - Make wrapper work for files on NFS filesystem.
7614 - Fix portability problem of MAXPATHLEN.
7615 - Fix array overrun problem in clean_env().
7616 - Fix allocation of PATH environment variable
7618 *) Removed extraneous blank line is description of mod_status chars.
7621 *) Logging of errors from the call_exec routine simply went nowhere,
7622 since the logfile fd has been closed, so now we send them to stderr.
7623 [Harald T. Alvestrand]
7625 *) Fixed core dump when DocumentRoot is a CGI.
7626 [Ben Laurie, reported by geddis@tesserae.com]
7628 *) Fixed potential file descriptor leak in mod_asis; updated it and
7629 http_core to use pfopen/pfclose instead of fopen/fclose.
7630 [Randy Terbush and Roy Fielding]
7632 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
7633 as the DEC Alpha which is 64-bit but uses 32-bit ints.
7634 [Dean Gaudet and Ken Coar]
7636 *) Return a 302 response code to the client when sending a redirect
7637 due to a missing trailing '/' on a directory instead of a 301; now
7638 it is cacheable. [Markus Gyger]
7640 *) Fix condition where, if a bad directive occurs in .htaccess, and
7641 sub_request() goes first to this directory, then log_reason() will
7642 SIGSEGV because it doesn't have initialized r->per_dir_config.
7643 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
7645 *) Fix handling of lang_index in is_variant_better(). This was
7646 causing problems which resulted in the server sending the
7647 wrong language document in some cases. [Petr Lampa]
7649 *) Remove free() from clean_env() in suexec wrapper. This was nuking
7650 the clean environment on some systems.
7652 *) Tweak byteserving code (e.g. serving PDF files) to work around
7653 bugs in Netscape Navigator and Microsoft Internet Explorer.
7654 Emit Content-Length header when sending multipart/byteranges.
7657 *) Port to HI-UX/WE2. [Nick Maclaren]
7659 *) Port to HP MPE operating system for HP 3000 machines
7660 [Mark Bixby <markb@cccd.edu>]
7662 *) Fixed bug which caused a segmentation fault if only one argument
7663 given to RLimit* directives. [Ed Korthof]
7665 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
7667 *) Improved buffered output to the client by delaying the flush decision
7668 until the BUFF code is actually about to read the next request.
7669 This fixes a problem introduced in 1.2b5 with clients that send
7670 an extra CRLF after a POST request. Also improved chunked output
7671 performance by combining writes using writev() and removing as
7672 many bflush() calls as possible. NOTE: Platforms without writev()
7673 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
7674 or Configure, unless we have already done so. [Dean Gaudet]
7676 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
7678 *) Fixed mod_info output corruption bug introduced by buffer overflow
7679 fixes. [Dean Gaudet]
7681 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
7682 for the special case of a 304 response. [Paul Sutton]
7684 *) Improved handling of TRACE method by bypassing normal method handling
7685 and header parsing routines; fixed Allow response to always allow TRACE.
7688 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
7690 *) Cleaned-up some of the generated HTML. [Ken Coar]
7692 Changes with Apache 1.2b6
7694 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
7696 *) Fix typo introduced in fix for potential infinite loop around
7697 accept() in child_main(). This change caused the rev to 1.2b6.
7698 1.2b5 was never a public beta.
7700 Changes with Apache 1.2b5
7702 *) Change KeepAlive semantics (On|Off instead of a number), add
7703 MaxKeepAliveRequests directive. [Alexei Kosut]
7705 *) Various NeXT compilation patches, as well as a change in
7706 regex/regcomp.c since that file also used a NEXT define.
7709 *) Allow * to terminate the end of a directory match in mod_dir.
7710 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
7712 *) Don't call can_exec() if suexec_enabled. Calling this requires
7713 scripts executed by the suexec wrapper to be world executable, which
7714 defeats one of the advantages of running the wrapper. [Randy Terbush]
7716 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
7719 *) Migration from sprintf() to snprintf() to avoid buffer
7720 overflows. [Marc Slemko]
7722 *) Provide portable snprintf() implementation (ap_snprintf)
7723 as well as *cvt family. [Jim Jagielski]
7725 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
7728 *) Remove mod_fastcgi.c from the distribution. This module appears
7729 to be maintained more through the Open Market channels and should
7730 continue to be easily available at http://www.fastcgi.com/
7732 *) Fixed bug in modules/Makefile that wouldn't allow building in more
7733 than one subdirectory (or cleaning, either). [Jeremy Laidman]
7735 *) mod_info assumed that the config files were relative to ServerRoot.
7738 *) CGI scripts called as an error document resulting from failed
7739 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
7741 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
7744 *) Properly check errno to prevent display of a directory index
7745 when server receives a long enough URL to confuse stat().
7748 *) Several security enhancements to suexec wrapper. It is _highly_
7749 recommended that previously installed versions of the wrapper
7750 be replaced with this version. [Randy Terbush, Jason Dour]
7752 - ~user execution now properly restricted to ~user's home
7753 directory and below.
7754 - execution restricted to UID/GID > 100
7755 - restrict passed environment to known variables
7756 - call setgid() before initgroups() (portability fix)
7757 - remove use of setenv() (portability fix)
7759 *) Add HTTP/1.0 response forcing. [Ben Laurie]
7761 *) Add access control via environment variables. [Ben Laurie]
7763 *) Add rflush() function. [Alexei Kosut]
7765 *) remove duplicate pcalloc() call in new_connection().
7767 *) Fix incorrect comparison which could allow number of children =
7768 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
7769 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
7771 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
7772 AIX PS/2, CONVEXOS. [Jim Jagielski]
7774 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
7775 It's more portable. [Martin Kraemer]
7777 *) Replace references to make in Makefile.tmpl with $(MAKE).
7780 *) Add ProxyBlock directive w/IP address caching. Add IP address
7781 caching to NoCache directive as well. ProxyBlock works with all
7782 handlers; NoCache now also works with FTP for anonymous logins.
7783 Still more code cleanup. [Chuck Murcko]
7785 *) Add "header parse" API hook [Ben Laurie]
7787 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
7789 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
7791 *) Correctly allow access and auth directives in <Files> sections in
7792 server config files. [Alexei Kosut]
7794 *) Fix bug with ServerPath that could cause certain files to be not
7795 found by the server. [Alexei Kosut]
7797 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
7798 double-quote from text and so that it properly checks for unsupported
7799 status codes using the new index_of_response interface. [Roy Fielding]
7801 *) Multiple fixes to the lingering_close code in order to avoid being
7802 interrupted by a stray timeout, to avoid lingering on a connection
7803 that has already been aborted or never really existed, to ensure that
7804 we stop lingering as soon as any error condition is received, and to
7805 prevent being stuck indefinitely if the read blocks. Also improves
7806 reporting of error conditions. [Marc Slemko and Roy Fielding]
7808 *) Fixed initialization of parameter structure for sigaction.
7809 [mgyger@itr.ch, Adrian Filipi-Martin]
7811 *) Fixed reinitializing the parameters before each call to accept and
7812 select, and removed potential for infinite loop in accept.
7813 [Roy Fielding, after useful PR from adrian@virginia.edu]
7815 *) Fixed condition where, if a child fails to fork, the scoreboard would
7816 continue to say SERVER_STARTING forever. Eventually, the main process
7817 would refuse to start new children because count_idle_servers() will
7818 count those SERVER_STARTING entries and will always report that there
7819 are enough idle servers. [Phillip Vandry]
7821 *) Fixed bug in bcwrite regarding failure to account for partial writes.
7822 Avoided calling bflush() when the client is pipelining requests.
7823 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
7825 *) Added description of "." mode in server-status [Jim Jagielski]
7827 Changes with Apache 1.2b4
7829 *) Fix possible race condition in accept_mutex_init() that
7830 could leave a small security hole open allowing files to be
7831 overwritten in cases where the server UID has write permissions.
7834 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
7836 *) Fix portablity problem in util_script where ARG_MAX may not be
7837 defined for some systems.
7839 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
7842 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
7843 style magic #! token for better script portability. [Garey Smiley]
7845 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
7846 execution for ~userdir CGI. [Jason Dour]
7848 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
7850 *) Fix month off by one in suexec wrapper logging.
7852 Changes with Apache 1.2b3:
7854 *) Fix error in mod_cgi which could cause resources not to be properly
7855 freed, or worse. [Dean Gaudet]
7857 *) Fix find_string() NULL pointer dereference. [Howard Fear]
7859 *) Add set_flag_slot() at the request of Dirk and others.
7862 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
7864 *) Add changes to improve the error message given for invalid
7865 ServerName parameters. [Dirk vanGulik]
7867 *) Add "Authoritative" directive for Auth modules that don't
7868 currently have it. This gives admin control to assign authoritative
7869 control to an authentication scheme and allow "fall through" for
7870 those authentication modules that aren't "Authoritative" thereby
7871 allowing multiple authentication mechanisms to be chained.
7874 *) Remove requirement for ResourceConfig/AccessConfig if not using
7875 the three config file layout. [Randy Terbush]
7877 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
7879 *) Changes to suexec wrapper to fix the following problems:
7880 1. symlinked homedirs will kill ~userdirs.
7881 2. initgroups() on Linux 2.0.x clobbers gr->grid.
7882 3. CGI command lines paramters problems
7883 4. pw-pwdir for "docroot check" still the httpd user's pw record.
7884 [Randy Terbush, Jason Dour]
7886 *) Change create_argv() to accept variable arguments. This fixes
7887 a problem where arguments were not getting passed to the CGI via
7888 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
7890 *) Collapse multiple slashes in path URLs to properly apply
7891 handlers defined by <Location>. [Alexei Kosut]
7893 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
7895 *) Improve the accuracy of request duration timings by setting
7896 r->request_time in read_request_line() instead of read_request().
7899 *) Reset timeout while reading via get_client_block() in mod_cgi.c
7900 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
7902 *) Add the ability to pass different Makefile.tmpl files to Configure
7903 using the -make flag. [Rob Hartill]
7905 *) Fix coredump triggered when sending a SIGHUP to the server caused
7906 by an assertion failure, in turn caused by an uninitialised field in a
7910 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
7911 PATH_INFO from previous versions of Apache (in certain situations,
7912 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
7913 [later removed in 1.2b11]
7915 *) Add rwrite() function to API to allow for sending strings of
7916 arbitrary length. [Doug MacEachern]
7918 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
7920 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
7921 NeXT. [Jim Jagielski]
7923 *) Removed recent modification to promote the status code on internal
7924 redirects, since the correct fix was to change the default log format
7925 in mod_log_config so that it outputs the original status. [Rob Hartill]
7927 Changes with Apache 1.2b2:
7929 *) Update set_signals() to use sigaction() for setting handlers.
7930 This appears to fix a re-entrant problem in the seg_fault()
7931 bus_error() handlers. [Randy Terbush]
7933 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
7935 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
7937 *) proxy_http.c bugfixes: [Chuck Murcko]
7938 1) fixes possible NULL pointer reference w/NoCache
7939 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
7940 host would cache nothing if it was in the local domain,
7941 and the local domain was in the NoCache list)
7942 3) Adds Host: header when not available
7943 4) Some code cleanup and clarification
7945 *) mod_include.c bugfixes:
7946 1) Fixed an ommission that caused include variables to not
7947 be parsed in config errmsg directives [Howard Fear]
7948 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
7949 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
7950 4) Allow backslash-escaping to all quoted text
7951 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
7952 5) Pass variable to command line if not set in XSSI's env
7955 *) Fix infinite loop when processing Content-language lines in
7956 type-map files. [Alexei Kosut]
7958 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
7960 *) Fixed problem in set_[user|group] that prevented CGI execution
7961 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
7963 *) Added PORTING information file. [Jim Jagielski]
7965 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
7967 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
7969 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
7970 USE_FCNTL_SERIALIZED_ACCEPT was intended.
7972 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
7973 which caused problems of systems where socket s_addr is >32bits.
7975 *) Added comment to explain (r->chunked = 1) side-effect in
7976 http_protocol.c [Roy Fielding]
7978 *) Replaced use of index() in mod_expires.c with more appropriate
7979 and portable isdigit() test. [Ben Laurie]
7981 *) Updated Configure for ...
7982 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
7983 *-dg-dgux* (bad pattern match)
7984 QNX (DEF_WANTHSREGEX=yes)
7985 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
7988 and added some user diagnostic info. [Ben Laurie]
7990 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
7991 for better portability. [Jim Jagielski]
7993 *) Updated helpers/GuessOS for ...
7994 SCO 5 (recognize minor releases)
7995 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
7996 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
7997 IRIX64 (-sgi-irix64)
7998 ULTRIX (-unknown-ultrix)
7999 SINIX (-whatever-sysv4)
8000 NCR Unix (-ncr-sysv4)
8001 and fixed something in helpers/PrintPath [Ben Laurie]
8003 Changes with Apache 1.2b1
8005 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
8007 Changes with Apache 1.1.1
8009 *) Fixed bug where Cookie module would make two entries in the
8010 logfile for each access [Mark Cox]
8012 *) Fixed bug where Redirect in .htaccess files would cause memory
8013 leak. [Nathan Neulinger]
8015 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
8017 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
8019 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
8021 Changes with Apache 1.1.0
8023 *) Bring NeXT support up to date. [Takaaki Matsumoto]
8025 *) Bring QNX support up to date. [Ben Laurie]
8027 *) Make virtual hosts default to main server keepalive parameters.
8028 [Alexei Kosut, Ben Laurie]
8030 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
8032 *) Fix missing address family for connect, also remove unreachable statement
8033 in mod_proxy. [Ben Laurie]
8035 *) mod_env now turned on by default in Configuration.tmpl.
8037 *) Bugs which were fixed:
8038 a) yet more mod_proxy bugs [Ben Laurie]
8039 b) CGI works again with inetd [Alexei Kosut]
8040 c) Leading colons were stripped from passwords [osm@interguide.com]
8041 d) Another fix to multi-method Limit problem [jk@tools.de]
8043 Changes with Apache 1.1b4
8045 *) r->bytes_sent variable restored. [Robert Thau]
8047 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
8049 *) More possibly unsecure programs removed from the support directory.
8051 *) More mod_auth_msql authentication improvements.
8053 *) VirtualHosts based on Host: headers no longer conflict with the
8056 *) OS/2 compatibility enhancements. [Gary Smiley]
8058 *) POST now allowed to directory index CGI scripts.
8060 *) Actions now work with files of the default type.
8062 *) Bugs which were fixed:
8063 a) more mod_proxy bugs
8064 b) early termination of inetd requests
8065 c) compile warnings on several systems
8066 d) problems when scripts stop reading output early
8068 Changes with Apache 1.1b3
8070 *) Much of cgi-bin and all of cgi-src has been removed, due to
8071 various security holes found and that we could no longer support
8074 *) The "Set-Cookie" header is now special-cased to not merge multiple
8075 instances, since certain popular browsers can not handle multiple
8076 Set-Cookie instructions in a single header. [Paul Sutton]
8078 *) rprintf() added to buffer code, occurrences of sprintf removed.
8081 *) CONNECT method for proxy module, which means tunneling SSL should work.
8082 (No crypto needed) Also a NoCache config directive.
8084 *) Several API additions: pstrndup(), table_unset() and get_token()
8085 functions now available to modules.
8087 *) mod_imap fixups, in particular Location: headers are now complete
8090 *) New "info" module which reports on installed module set through a
8091 special URL, a la mod_status.
8093 *) "ServerPath" directive added - allows for graceful transition
8094 for Host:-header-based virtual hosts.
8096 *) Anonymous authentication module improvements.
8098 *) MSQL authentication module improvements.
8100 *) Status module design improved - output now table-based. [Ben Laurie]
8102 *) htdigest utility included for use with digest authentication
8105 *) mod_negotiation: Accept values with wildcards to be treated with
8106 less priority than those without wildcards at the same quality
8107 value. [Alexei Kosut]
8109 *) Bugs which were fixed:
8110 a) numerous mod_proxy bugs
8111 b) CGI early-termination bug [Ben Laurie]
8112 c) Keepalives not working with virtual hosts
8113 d) RefererIgnore problems
8114 e) closing fd's twice in mod_include (causing core dumps on
8115 Linux and elsewhere).
8117 Changes with Apache 1.1b2
8120 a) core dumps in mod_digest
8121 b) truncated hostnames/ip address in the logs
8122 c) relative URL's in mod_imap map files
8124 Changes with Apache 1.1b1
8126 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
8128 Changes with Apache 1.0.3
8130 *) Internal redirects which occur in mod_dir.c now preserve the
8131 query portion of a request (the bit after the question mark).
8134 *) Escape active characters '<', '>' and '&' in html output in
8135 directory listings, error messages and redirection links.
8138 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
8140 *) Fix for POSIX compliance in waiting for processes in alloc.c.
8143 *) setsockopt no longer takes a const declared argument [Martijn Koster]
8145 *) Reset timeout timer after each successful fwrite() to the network.
8146 This patch adds a reset_timeout() procedure that is called by
8147 send_fd() to reset the timeout ever time data is written to the net.
8150 *) timeout() signal handler now checks for SIGPIPE and reports
8151 lost connections in a more user friendly way. [Rob Hartill]
8153 *) Location of the "scoreboard" file which used to live in /tmp is
8154 now configurable (for OSes that can't use mmap) via ScoreBoardFile
8155 which works similar to PidFile (in httpd.conf) [Rob Hartill]
8157 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
8159 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
8160 which caused a SEGV with cookies enabled
8162 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
8165 *) Log the UNIX textual error returned by some system calls, in
8166 particular errors from accept() [David Robinson]
8168 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
8170 Changes with Apache 1.0.2
8172 *) patch to get Apache compiled on UnixWare 2.x, recommended as
8173 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
8175 *) Fix get_basic_auth_pw() to set the auth_type of the request.
8178 *) past changes to http_config.c to only use the
8179 setrlimit function on systems defining RLIMIT_NOFILE
8180 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
8181 for SUNOS and prototypes the needed functions.
8183 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
8186 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
8188 *) Merge multiple headers from CGI scripts instead of taking last
8189 one. [David Robinson]
8191 *) Add support for SCO 5. [Ben Laurie]
8193 Changes with Apache 1.0.1
8195 *) Silence mod_log_referer and mod_log_agent if not configured
8198 *) Recursive includes can occur if the client supplies PATH_INFO data
8199 and the server provider uses relative links; as file.html
8200 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
8202 *) The replacement for initgroups() did not call {set,end}grent(). This
8203 had two implications: if anything else used getgrent(), then
8204 initgroups() would fail, and it was consuming a file descriptor.
8207 *) On heavily loaded servers it was possible for the scoreboard to get
8208 out of sync with reality, as a result of a race condition.
8209 The observed symptoms are far more Apaches running than should
8210 be, and heavy system loads, generally followed by catastrophic
8211 system failure. [Ben Laurie]
8213 *) Fix typo in license. [David Robinson]
8215 Changes with Apache 1.0.0 23 Nov 1995
8217 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
8219 Changes with Apache 0.8.16 05 Nov 1995
8221 *) New man page for 'httpd' added to support directory [David Robinson]
8223 *) .htgroup files can have more than one line giving members for a
8224 given group (each must have the group name in front), for NCSA
8225 back-compatibility [Robert Thau]
8227 *) Mutual exclusion around accept() is on by default for SVR4 systems
8228 generally, since they generally can't handle multiple processes in
8229 accept() on the same socket. This should cure flaky behavior on
8230 a lot of those systems. [David Robinson]
8232 *) AddType, AddEncoding, and AddLanguage directives take multiple
8233 extensions on a single command line [David Robinson]
8235 *) UserDir can be disabled for a given virtual host by saying
8236 "UserDir disabled" in the <VirtualHost> section --- it was a bug
8237 that this didn't work. [David Robinson]
8239 *) Compiles on QNX [Ben Laurie]
8241 *) Corrected parsing of ctime time format [David Robinson]
8243 *) httpd does a perror() before exiting if it can't log its pid
8244 to the PidFile, to make diagnosing the error a bit easier.
8247 *) <!--#include file="..."--> can no longer include files in the
8248 parent directory, for NCSA back-compatibility. [David Robinson]
8250 *) '~' is *not* escaped in URIs generated for directory listings
8253 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
8255 *) Fixed bug involving handling URIs with escaped %-characters
8256 in redirects [David Robinson]
8258 Changes with Apache 0.8.15 14 Oct 1995
8260 *) Switched to new, simpler license
8262 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
8264 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
8266 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
8268 *) Correctly handles internal redirects to files with names containing '%'
8271 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
8273 *) Use geteuid() rather than getuid() to see if we have root privilege,
8274 so that server correctly resets privilege if run setuid root. [Andrew
8277 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
8280 *) Fix relative URLs in imagemap files [Randy Terbush]
8282 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
8285 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
8286 entries all name the same one. [David Robinson]
8288 *) Fix directory listings with filenames containing unusual characters
8291 *) Better URI-escaping for generated URIs in directories with filenames
8292 containing unusual characters [Ben Laurie]
8294 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
8296 *) Unblock alarms on error return from spawn_child() [David Robinson]
8298 *) Sample Config files have extra note for SCO users [Ben Laurie]
8300 *) Configuration has note for HP-UX users [Rob Hartill]
8302 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
8304 *) Nuked bogus #define in httpd.h [David Robinson]
8306 *) Better test for whether a system has setrlimit() [David Robinson]
8308 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
8310 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
8313 Changes with Apache 0.8.14 19 Sep 1995
8315 *) Compiles on SCO ODT 3.0 [Ben Laurie]
8317 *) AddDescription works (better) [Ben Laurie]
8319 *) Leaves an intelligible error diagnostic when it can't set group
8320 privileges on standalone startup [Andrew Wilson]
8322 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
8323 that machine, which claims to be BSD but does not support RLIMIT.
8326 *) gcc -Wall no longer complains about an unused variable when util.c
8327 is compiled with -DMINIMAL_DNS [Andrew Wilson]
8329 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
8331 Changes with Apache 0.8.13 07 Sep 1995
8333 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
8335 *) Have built-in imagemap code recognize & honor Point directive [James
8338 *) Generate cleaner directory listings in directories with a mix of
8339 long and short filenames [Rob Hartill]
8341 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
8343 *) Properly default ServerName for virtual servers [Robert Thau]
8345 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
8346 Paul Richards and a cast of thousands...]
8348 *) On self-identified BSD systems (we don't try to guess any more),
8349 allocate a few extra file descriptors per virtual host with setrlimit,
8350 if we can, to avoid running out. [Randy Terbush]
8352 *) Write 22-character lock file name into buffer with enough space
8353 on startup [Konstantin Olchanski]
8355 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
8358 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
8360 *) Suppress -Wall warning by initializing variable in negotiation code
8361 [Tobias Weingartner]
8363 Changes with Apache 0.8.12 31 Aug 1995
8365 *) Doesn't pause three seconds after including a CGI script which is
8366 too slow to die off (this is done by not even trying to kill off
8367 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
8368 after the entire document has been processed). [Robert Thau]
8370 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
8372 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
8374 *) Allows .htaccess files to override <Directory> sections naming the
8375 same directory [David Robinson]
8377 *) Removed an efficiency hack in sub_req_lookup_uri which was
8378 causing certain extremely marginal cases (e.g., ScriptAlias of a
8379 *particular* index.html file) to fail. [David Robinson]
8381 *) Doesn't log an error when the requested URI requires
8382 authentication, but no auth header line was supplied by the
8383 client; this is a normal condition (the client doesn't no auth is
8384 needed here yet). [Robert Thau]
8386 *) Behaves more sanely when the name server loses its mind [Sean Welch]
8388 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
8390 *) RFC931 code no longer passes out name of prior clients on current
8391 requests if the current request came from a server that doesn't
8392 do RFC931. [David Robinson]
8394 *) Configuration script accepts "Module" lines with trailing whitespace.
8397 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
8399 *) Cleaned up comments in mod_cgi.c [Robert Thau]
8401 Changes with Apache 0.8.11 24 Aug 1995
8403 *) Wildcard <Directory> specifications work. [Robert Thau]
8405 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
8407 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
8408 the file being requested itself, in addition to the directories leading
8409 up to it. [Robert Thau]
8411 *) Logs access failures due to symlink checks or invalid client address
8412 in the error log [Roy Fielding, Robert Thau]
8414 *) Symlink checks deal correctly with systems where lstat of
8415 "/path/to/some/link/" follows the link. [Thau, Fielding]
8417 *) Doesn't reset DirectoryIndex to 'index.html' when
8418 other directory options are set in a .htaccess file. [Robert Thau]
8420 *) Clarified init code and nuked bogus warning in mod_access.c
8423 *) Corrected several directives in sample srm.conf
8424 --- includes corrections to directory indexing icon-related directives
8425 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
8426 icons for encodings right, and turning on AddEncoding by default).
8429 *) Corrected descriptions of args to AddIcon and AddAlt in command table
8432 *) INSTALL & README mention "contributed modules" directory [Brian
8435 *) Fixed English in the license language... "for for" --> "for".
8438 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
8439 mod_alias.c, merging it almost completely with handling of Alias, and
8440 adding a 'notes' field to the request_rec which allows the CGI module
8441 to discover whether the Alias module has put this request through
8442 ScriptAlias (which it needs to know for back-compatibility, as the old
8443 NCSA code did not check Options ExecCGI in ScriptAlias directories).
8446 Changes with Apache 0.8.10 18 Aug 1995
8448 *) AllowOverride applies to the named directory, and not just
8449 subdirectories. [David Robinson]
8451 *) Do locking for accept() exclusion (on systems that need it)
8452 using a special file created for the purpose in /usr/tmp, and
8453 not the error log; using the error log causes real problems
8454 if it's NFS-mounted; this is known to be the cause of a whole
8455 lot of "server hang" problems with Solaris. [David Robinson;
8456 thanks to Merten Schumann for help diagnosing the problem].
8458 Changes with Apache 0.8.9 12 Aug 1995
8460 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
8462 *) Nested includes see environment variables of the including document,
8463 for NCSA bug-compatibility (some sites have standard footer includes
8464 which try to print out the last-modified date). [Eric Hagberg/Robert
8467 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
8468 URI as a CGI script, even if it would have been treated as something
8469 else if requested directly, for NCSA back-compatibility. (Note that
8470 this means that people who know the name of the script can see the
8471 code just by asking for it). [Robert Thau]
8473 *) New version of dbmmanage script included in support directory as
8476 *) Check if scoreboard file couldn't be opened, and say so, rather
8477 then going insane [David Robinson]
8479 *) POST to CGI works on A/UX [Jim Jagielski]
8481 *) AddIcon and AddAlt commands work properly [Rob Hartill]
8483 *) NCSA server push works properly --- the Arena bug compatibility
8484 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
8485 if you still want the workaround). [Rob Hartill]
8487 *) If client didn't submit any Accept-encodings, ignore encodings in
8488 content negotiation. (NB this will all have to be reworked anyway
8489 for the new HTTP draft). [Florent Guillaume]
8491 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
8493 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
8495 *) Give Redirect priority over Alias, for NCSA bug compatibility
8498 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
8499 paralleling earlier bug fix for CGI [David Robinson]
8501 *) If DBM auth is improperly configured, report a server error and don't
8504 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
8505 it seems to work well enough without it (even in a 10 hits/sec
8506 workout), and the overhead for the locking under A/UX is
8507 alarmingly high (though it is very low on other systems).
8508 [Eric Hagberg, Jim Jagielski]
8510 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
8512 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
8513 Behlendorf/Eric Hagberg]
8515 *) More improvements to default Configuration for A/UX [Jim Jagielski]
8517 *) Compiles clean on NEXT [Rob Hartill]
8519 *) Compiles clean on SGI [Robert Thau]
8521 Changes with Apache 0.8.8 08 Aug 1995
8523 *) SunOS library prototypes now never included unless explicitly
8524 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
8525 people using GNU libc on SunOS are screwed by prototypes for the
8528 (Those who wish to compile clean with gcc -Wall on a standard
8529 SunOS setup need the prototypes, and may obtain them using
8530 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
8531 with nonstandard libraries are presumably competent to make their
8534 *) Strips trailing '/' characters off both args to the Alias command,
8535 to make 'Alias /foo/ /bar/' work.
8537 Changes with Apache 0.8.7 03 Aug 1995
8539 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
8540 [reported by David Robinson]
8542 *) Compiles clean on OSF/1 [David Robinson]
8544 *) Added some of the more recent significant changes (AddLanguage stuff,
8545 experimental LogFormat support) to CHANGES file in distribution root
8548 Changes with Apache 0.8.6 02 Aug 1995
8550 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
8551 (If you actually wanted a conditional GET which bypassed the cache, you
8552 couldn't get it). [Reported by Roy Fielding]
8554 *) Properly terminate headers on '304 Not Modified' replies to conditional
8555 GETs --- no browser we can find cares much, but the CERN proxy chokes.
8556 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
8558 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
8560 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
8561 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
8562 and older versions don't set the __SUNPRO_C preprocessor variable). On
8563 all other systems, these are never used anyway. [Reported by Mark Cox].
8565 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
8567 Changes with Apache 0.8.5 01 Aug 1995
8569 *) Added last-minute configurable log experiment, as optional module
8571 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
8572 properly. (One-line fix to http_protocol.c).
8574 *) Work around bogus behavior when reloading from Netscape.
8575 It's Netscape's bug --- for some reason they expect a request with
8576 If-modified-since: to not function as a conditional GET if it also
8577 comes with Pragma: no-cache, which is way out of line with the HTTP
8578 spec (according to Roy Fielding, the redactor).
8580 *) Added parameter to set maximum number of server processes.
8582 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
8585 *) IdentityCheck bugfix [Chuck Murcko].
8587 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
8589 *) More sample config file corrections; add extension to AddType for
8590 *.asis, move AddType generic description to its proper place, and
8591 fix miscellaneous typos. [ Alexei Kosut ]
8593 *) Deleted the *other* reference to the regents from the Berkeley
8594 legal disclaimer (everyplace).
8596 *) Nuked Shambhala name from src/README; had already cleaned it out
8599 Changes with Apache 0.8.4
8601 *) Changes to server-pool management parms --- renamed current
8602 StartServers to MinSpareServers, created separate StartServers
8603 parameter which means what it says, and renamed MaxServers to
8604 MaxSpareServers (though the old name still works, for NCSA 1.4
8605 back-compatibility). The old names were generally regarded as
8606 too confusing. Also altered "docs" in sample config files.
8608 *) More improvements to default config files ---
8609 sample directives (commented out) for XBitHack, BindAddress,
8610 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
8611 defaults, AddTypes for send-as-is and imagemap magic types, and
8612 improvements to samples for DirectoryIndex [Alexei Kosut]
8614 *) Yet more improvements to default config files --- changes to
8615 Alexei's sample AddLanguage directives, and sample LanguagePriority
8616 [ Florent Guillaume ]
8618 *) Set config file locations properly if not set in httpd.conf
8621 *) Don't escape URIs in internal redirects multiple times; don't
8622 do that when translating PATH_INFO to PATH_TRANSLATED either.
8625 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
8627 Changes with Apache 0.8.3
8629 *) Edited distribution README to *briefly* summarize installation
8630 procedures, and give a pointer to the INSTALL file in the src/
8633 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
8634 recent NCSA distributions.
8636 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
8637 exist for the same directory, use both and don't segfault. [Reported
8640 *) Proper makefile dependencies [David Robinson]
8642 *) Note (re)starts in error log --- reported by Rob Hartill.
8644 *) Only call no2slash() after get_path_info() has been done, to
8645 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
8646 reported by Andrew Wilson, though this one is probably a real bug]
8648 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
8649 dump core when Referer is not supplied. [Randy Terbush]
8651 *) Lightly edited sample config files to refer people to our documentation
8652 instead of NCSA's, and to list Rob McCool as *original* author (also
8653 deleted his old, and no doubt non-functional email address). Would be
8654 nice to have examples of new features...
8656 Changes with Apache 0.8.2 19 Jul 1995
8658 *) Added AddLanuage code [Florent Guillaume]
8660 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
8662 *) All sorts of problems when MultiViews finds a directory. It would
8663 be nice if mod_dir.c was robust enough to handle that, but for now,
8664 just punt. [reported by Brian Behlendorf]
8666 *) Wait for all children on restart, to make sure that the old socket
8667 is gone and we can reopen it. [reported by Randy Terbush]
8669 *) Imagemap module is enabled in default Configuration
8671 *) RefererLog and UserAgentLog modules properly default the logfile
8674 *) Mark Cox's mod_cookies added to the distribution as an optional
8675 module (commented out in the default Configuration, and noted as
8676 an experiment, along with mod_dld). [Mark Cox]
8678 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
8680 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
8682 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
8684 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
8687 Changes with Apache 0.8.1
8689 *) New imagemap module [Randy Terbush]
8691 *) Replacement referer log module with NCSA-compatible RefererIgnore
8692 [Matthew Gray again]
8694 *) Don't mung directory listings with very long filenames.
8697 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
8699 *) New config script. See INSTALL for info. [Robert Thau]
8701 *) Scoreboard mechanism for regulating the number of extant server
8702 processes. MaxServers and StartServers defaults are the same as
8703 for NCSA, but the meanings are slightly different. (Actually,
8704 I should probably lower the MaxServers default to 10).
8706 Before asking for a new connection, each server process checks
8707 the number of other servers which are also waiting for a
8708 connection. If there are more than MaxServers, it quietly dies
8709 off. Conversely, every second, the root, or caretaker, process
8710 looks to see how many servers are waiting for a new connection;
8711 if there are fewer than StartServers, it starts a new one. This
8712 does not depend on the number of server processes already extant.
8713 The accounting is arranged through a "scoreboard" file, named
8714 /tmp/htstatus.*, on which each process has an independent file
8715 descriptor (they need to seek without interference).
8717 The end effect is that MaxServers is the maximum number of
8718 servers on an *inactive* server machine, but more will be forked
8719 off to handle unusually heavy loads (or unusually slow clients);
8720 these will die off when they are no longer needed --- without
8721 reverting to the overhead of full forking operation. There is a
8722 hard maximum of 150 server processes compiled in, largely to
8723 avoid forking out of control and dragging the machine down.
8724 (This is arguably too high).
8726 In my server endurance tests, this mechanism did not appear to
8727 impose any significant overhead, even after I forced it to put the
8728 scoreboard file on a normal filesystem (which might have more
8729 overhead than tmpfs). [Robert Thau]
8731 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
8734 *) Read .htaccess files even in directory with <Directory> section.
8735 (Former incompatibility noted on mailing list, now fixed). [Robert
8738 *) "HEAD /" gives the client a "Bad Request" error message, rather
8739 than trying to send no body *and* no headers. [Cliff Skolnick].
8741 *) Don't produce double error reports for some very obscure cases
8742 mainly involving auth configuration (the "all modules decline to
8743 handle" case which is a sure sign of a server bug in most cases,
8744 but also happens when authentication is badly misconfigured).
8747 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
8748 it's *for*, and this sort of thing really shouldn't be cluttering
8749 up the Makefile). [Robert Thau]
8751 *) Incidental code cleanups in http_main.c --- stop dragging
8752 sa_client around; just declare it where used. [Robert Thau]
8754 *) Another acc-related fix. (It doesn't like const char
8755 in some places...). [Mark Cox]
8757 Changes with Shambhala 0.6.1 13 Jul 1995
8759 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
8760 Also, fixed auth typo in http_protocol.c unmasked by this fix.
8762 *) Compiles clean with acc on SunOS [Paul Sutton]
8764 *) Reordered modules in modules.c so that Redirect takes priority
8765 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
8766 believe it or not, he has an actual site with a ScriptAlias and
8767 a Redirect declared for the *exact same directory*. Even *my*
8768 compatibility fetish wouldn't motivate me to fix this if the fix
8769 required any effort, but it doesn't, so what the hey.
8771 *) Fixed to properly default several server_rec fields for virtual
8772 servers from the corresponding fields in the main server_rec.
8773 [Cliff Skolnick --- 'port' was a particular irritant].
8775 *) No longer kills off nph- child processes before they are
8776 finished sending output. [Matthew Gray]
8778 Changes with Shambhala 0.6.0 10 Jul 1995
8780 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
8781 the connection to the client in an "aborted" state, but otherwise
8782 allow whatever handlers are running to clean up. hard_timeout()s
8783 abort the request in progress completely; anything not tied to some
8784 resource pool cleanup will leak. They're still around because I
8785 haven't yet come up with a more elegant way of handling
8786 timeouts when talking to something that isn't the client. The
8787 default_handler and the dir_handler now use soft timeouts, largely
8788 so I can test the feature. [Robert Thau]
8790 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
8791 the case of log handlers dying prematurely is probably handled VERY
8792 gracelessly at this point, and if the logger stops reading input,
8793 the server will hang. (It is known to correctly restart the
8794 logging process on server restart; this is (should be!) going through
8795 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
8796 script). [Robert Thau]
8798 *) asis files supported (new module). [Robert Thau]
8800 *) IdentityCheck code is compiled in, but has not been tested. (I
8801 don't know anyone who runs identd). [Robert Thau]
8803 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
8804 came in with the request, for NCSA bug-compatibility. [Robert Thau]
8806 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
8808 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
8809 as timeouts are not in scope. [Robert Thau]
8811 *) quoted-string args in config files now handled correctly (doesn't drop
8812 the last character). [Robert Thau; reported by Randy Terbush]
8814 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
8815 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
8817 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
8818 default default type); the former default default behavior when all
8819 type-checkers defaulted had been a core dump. [Paul Sutton]
8821 *) Copy filenames out of the struct dirent when indexing
8822 directories. (On Linux, readdir() returns a pointer to the same
8823 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
8825 Changes with Shambhala 0.5.3 [not released]
8827 *) Default response handler notes "file not found" in the error log,
8828 if the file was not found. [Cliff Skolnick].
8830 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
8831 code no longer sets up bogus PATH_INFO which fakes out the directory
8832 handler). [Cliff Skolnick]
8834 Changes with Shambhala 0.5.2 06 Jul 1995
8836 *) Changes to http_main.c --- root server no longer plays silly
8837 games with SIGCHLD, and so now detects and replaces dying
8838 children. Child processes just die on SIGTERM, without taking
8839 the whole process group with them. Potential problem --- if any
8840 child process refuses to die, we hang in restart.
8841 MaxRequestsPerChild may still not work, but it certainly works
8842 better than it did before this! [Robert Thau]
8844 *) mod_dir.c bug fixes: ReadmeName and HeaderName
8845 work (or work better, at least); over-long description lines
8846 properly terminated. [Mark Cox]
8848 *) http_request.c now calls unescape_url() more places where it
8849 should [Paul Sutton].
8851 *) More directory handling bugs (reported by Cox)
8852 Parent Directory link is now set correctly. [Robert Thau]
8854 Changes with Shambhala 0.5.1 04 Jul 1995
8856 *) Generalized cleanup interface in alloc.c --- any function can be
8857 registered with alloc.c as a cleanup for a resource pool;
8858 tracking of files and file descriptors has been reimplemented in
8859 terms of this interface, so I can give it some sort of a test.
8862 *) More changes in alloc.c --- new cleanup_for_exec() function,
8863 which tracks down and closes all file descriptors which have been
8864 registered with the alloc.c machinery before the server exec()s a
8865 child process for CGI or <!--#exec-->. CGI children now get
8866 started with exactly three file descriptors open. Hopefully,
8867 this cures the problem Rob H. was having with overly persistent
8868 CGI connections. [Robert Thau]
8870 *) Mutual exclusion around the accept() in child_main() --- this is
8871 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
8872 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
8873 This uses fcntl(F_SETLK,...) on the error log descriptor because
8874 flock() on that descriptor won't work on systems which have BSD
8875 flock() semantics, including (I think) Linux 1.3 and Solaris.
8877 This does work on SunOS (when the server is idle, only one
8878 process in the pool is waiting on accept()); it *ought* to work
8879 on the other systems. [Robert Thau]
8881 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
8883 *) sizeof(*sa_client) bugfix from [Rob Hartill]
8885 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
8887 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
8888 be unnecessary if I go to the revised timeout-handling scheme).
8891 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
8892 string) even if none came in with the request. [Robert Thau]
8894 *) CHANGES file added to distribution ;-).
8896 Changes with Shambhala 0.4.5
8898 *) mod_dld --- early dynamic loading support [rst]
8899 *) Add wildcard content handlers for XBITHACK; default_hander now
8900 invoked with that mechanism (as a handler hanging off mod_core) [rst]
8901 *) XBITHACK supported as a wildcard content-handler, and
8902 configurable at run-time (not just at compile time, as in the
8903 "patchy server" releases) [rst]
8905 Changes with Shambhala 0.4.4 30 Jun 1995
8907 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
8908 *) Handle Addtype x/y .z [rst, reported by Cox]
8910 Changes with Shambhala 0.4.3
8912 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
8913 synonymous [rst, terbush]
8915 Changes with Shambhala 0.4.1 28 Jun 1995
8917 *) First-cut virtual host implementation; some refit in the config
8918 reading code, and log management, was necessary to support this [rst]
8919 *) Sub-pool machinery, originally added to avoid excessive storage
8920 allocation on listings of large directories (which turned out to
8921 be the problem that the 0.3 storage accounting was added to
8922 find). Subrequests and mod_dir changed to use subpools. [rst]
8923 *) More memory debugging --- free list consistency checks. [rst]
8924 *) Added err_headers to request_rec, with support elsewhere [rst]
8925 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
8927 Changes with Shambhala 0.3 19 Jun 1995
8929 *) Switch ONE_PROCESS to a runtime command-line option (-X)
8930 *) Don't compile in mod_ai_backcompat by default
8931 *) Switch name of server from Apache to Shambhala in Makefile
8932 *) Add some accounting routines to track memory usage in the pools,
8935 Changes with Shambhala 0.2
8937 *) Set DOCUMENT_ROOT CGI variable
8938 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
8939 *) Add critical section protection to handling of cleanup structures
8941 *) Significant code reorg within the server core to group related
8942 functions together [rst]
8943 *) Correctly handle clients that hang up before sending any request
8945 *) Replace dying child processes. [rst]
8947 Changes with Shambhala 0.1 12 Jun 1995
8949 Major rewrite of the pre-existing "patchy server" codebase, by
8950 Robert Thau (rst). Significant portions of the server code, such
8951 as configuration-file handling and HTTP authentication support,
8952 were ripped out and rewritten from scratch. Code that was not
8953 completely rewritten was significantly altered.
8955 Major changes with this release include:
8957 *) Introduction of the module API; in request handling, the central
8958 machinery just dispatches to various modules, which actually do
8959 most of the work. Configuration handling is similar --- modules
8960 declare their own commands, and the central machinery just
8963 API features from shambhala/0.1 were substantially unchanged in
8964 Apache 1.0 and 1.1. (1.0 API features not yet present in this
8965 release, such as wildcard handlers and subpools, were added in
8966 subsequent Shambhala releases, and were also generally rst's
8969 *) This release included the following modules:
8971 mod_access (access control --- allow and deny directives),
8972 mod_alias (Alias and Redirect commands),
8973 mod_auth (straight HTTP authentication, based on flat-files)
8974 mod_auth_dbm (same, with dbm files)
8975 mod_cgi (CGI scripts and, in this release, ScriptAlias)
8976 mod_common_log (CLF access logs; later renamed mod_log_common)
8977 mod_dir (directory indexing)
8978 mod_include (server-side includes)
8979 mod_mime (AddType directives)
8980 mod_negotiation (content negotiation)
8981 mod_userdir (support for users' public_html directories)
8983 It also included a mod_ai_backcompat, which was a private hack
8984 for back-compatibility with rst's own AI-lab servers.
8986 All of these modules were substantially complete, and functional
8987 or nearly so (a few, which implemented features not in use at
8988 Thau's site, required patches of a few lines).
8990 *) sub-request machinery, to allow modules to determine how other
8991 modules would assign MIME types to a given file, or optionally
8992 serve its content (this is heavily used by mod_dir, mod_include
8993 and mod_negotiation).
8995 *) Resource pool system for keeping track of memory allocated and
8996 files opened in service of a particular request. Much of the
8997 code in the modules (when they weren't rewrites) was adjusted to
8998 replace a pervasive convention of using fixed-size buffers on
8999 the stack with an equally pervasive convention of using memory
9000 allocated with palloc().
9002 *) Reorganization of data structures associated with a given
9003 request to eliminate use of global variables and the troublesome
9004 unmunge_name function (used in NCSA and early Apache releases to
9005 attempt to determine the URI which mapped to a given filename
9006 --- a difficult proposition, given that it is easy to produce
9007 setups in which multiple URIs map to the same file).
9009 *) Source files renamed and rearranged
9011 *) Very simple pre-forking behavior --- parent process forked off a
9012 fixed number of children, and then just waited for SIGHUP.
9014 *) Other more minor changes too numerous to list.
9016 This release included modified versions of a lot of code from the
9017 Apache 0.6.4 public release, plus an early pre-forking patch
9018 codeveloped by Robert Thau and Rob Hartill.
9020 Changes with Apache 0.7.3 20 Jun 1995
9022 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
9023 were incorporated by Rob Hartill on the main branch while Robert Thau
9024 worked on the Shambhala rewrite above. Most were merged into the
9025 Shambala architecture after Apache 0.8.0.
9027 Changes with Apache 0.6.4 13 May 1995
9029 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
9032 Changes with Apache 0.5.1 10 Apr 1995
9034 Changes with Apache 0.4 02 Apr 1995
9036 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
9039 Changes with Apache 0.3 24 Mar 1995
9041 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
9044 Changes with Apache 0.2 18 Mar 1995
9046 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
9047 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
9048 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
