1 Changes with Apache 2.0b1
3 *) Allow mod_tls to compile under Unix boxes where openssl has been
4 installed to the system include files.
5 [Gomez Henri <new-httpd@slib.fr>]
7 *) Cleanup the mod_tls configure process. This should remove any need
8 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
9 configure doesn't check that yet. [Ryan Bloom]
11 *) Add a very early prototype of SSL support (in mod_tls.c). It is
12 vital that you read modules/tls/README before attempting to build
15 *) Fix a potential seg fault on all platforms. David Reid fixed this
16 on BEOS, but the problem could happen anywhere, so we don't want
17 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
19 *) Add new LogFormat directive, %D, to log time it takes to serve a
20 request in microseconds. [Bill Stoddard]
22 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
23 SetOutputFilter. This corresponds nicely with the other Set
24 directives, which operate on containers while the Add* directives
25 tend to work directly on extensions. [Ryan Bloom]
27 *) Cleanup the header handling a bit. This uses the apr_brigade_*
28 functions for the buffering so that we don't need to compute
29 the length of the headers before we actually create the header
32 *) Allow filters to buffer data using the ap_f* functions. These have
33 become macros that resolve directly to apr_brigade_*.
36 *) Get the Unix MPM's to do a graceful restart again. If we are going
37 to register a cleanup with ap_cleanup_scoreboard, then we have to
38 kill the cleanup with the same function, and that function can't be
41 *) Install all required header files. Without these, it was not
42 possible to compile some modules outside of the server.
45 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
46 forward from 1.3 to 2.0, we missed a single line, which broke regex
49 *) We have a poor abstraction in the protocol. This is a temporary
50 hack to fix the bug, but it will need to be fixed for real. If
51 we find an error while sending out a custom error response, we back
52 up to the first non-OK request and send the data. Then, when we send
53 the EOS from finalize_request_protocol, we go to the last request,
54 to ensure that we aren't sending an EOS to a request that has already
55 received one. Because the data is sent on a different request than
56 the EOS, the error text never gets sent down the filter stack. This
57 fixes the problem by finding the last request, and sending the data
58 with that request. [Ryan Bloom]
60 *) Make the server status page show the correct restart time, and
61 thus the proper uptime. [Ryan Bloom]
63 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
64 should reduce the amount of duplicate code that is required to
66 [Paul J. Reder <rederpj@raleigh.ibm.com>]
68 *) ap_new_connection() closes the socket and returns NULL if a socket
69 call fails. Usually this is due to a connection which has been
72 *) Move the Apache version information out of httpd.h and into release.h.
73 This is in preparation for the first tag with the new tag and release
76 *) Begin restructuring scoreboard code to enable adding back in
77 the ability to use IPC other than shared memory.
78 Get mod_status working on Windows again. [Bill Stoddard]
80 *) Make mod_status work with 2.0. This will work for prefork,
81 mpmt_pthread, and dexter. [Ryan Bloom]
83 *) Correct a typo in httpd.conf.
84 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
86 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
88 *) Get the correct IP address if ServerName isn't set and we can't
89 find a fully-qualified domain name at startup.
90 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
92 *) Make mod_cgid work with SuExec. [Ryan Bloom]
94 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
95 'extra' stat's for user/group since they should never occur, and now
96 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
97 volumes. [William Rowe]
99 *) Adopt apr features to simplify mod_includes. This changes the
100 behavior of the USER_NAME variable, unknown uid's are now reported
101 as USER_NAME="<unknown>" rather than the old user#000 result.
102 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
104 *) Adopt apr features for simplifing mod_userdir, and accept the new
105 Win32/OS2 exceptions without hiccuping. [William Rowe]
107 *) Replace configure --with-optim option by using and saving the
108 environment variable OPTIM instead. This is needed because configure
109 options do not support multiple flags separated by spaces.
112 *) Fix some byterange handling. If we get a byte range that looks like
113 "-999999" where that is past the end of the file, we should return
114 a PARTIAL CONTENT status code, and return the whole file as one big
115 byterange. This matches the 1.3 handling now. [Ryan Bloom]
117 *) Make the error bucket a real meta-data bucket. This means that the
118 bucket length is 0, and a read returns NULL data. If one of these
119 buckets is passed down after the headers are sent, this data will
120 just be ignored. [Greg Stein]
122 *) The prefork MPM wasn't killing child processes correctly if a restart
123 signal was received while the process was serving a request. The child
124 process would become the equivalent of a second parent process. If
125 we break out of the accept loop, then we need to do die after cleaning
126 up after ourselves. [Ryan Bloom]
128 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
129 restarts. [Ryan Bloom]
131 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
132 the most optimal APR_FINFO_wanted bits. This spares Win32 from
133 performing very expensive owner, group and permission lookups
134 and allows the server to function until these apr_finfo_t fields
135 are implemented under Win32. [William Rowe]
137 *) Support for typedsafe optional functions - that is functions exported by
138 optional modules, which, therefore, may or may not be present, depending
139 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
140 for sample code. [Ben Laurie]
142 *) filters can now report an HTTP error to the server. This is done
143 by sending a brigade where the first bucket is an error_bucket.
144 This bucket is a simple bucket that stores an HTTP error and
145 a string. Currently the string is not used, but it may be needed
146 to output an error log. The http_header_filter will find this
147 bucket, and output the error text, and then return
148 AP_FILTER_ERROR, which informs the server that the error web page
149 has already been sent. [Ryan Bloom]
151 *) If we get an error, then we should remove all filters except for
152 those critical to serving a web page. This fixes a bug, where
153 error pages were going through the byterange filter, even though
154 that made no sense. [Ryan Bloom]
156 *) Relax the syntax checking of Host: headers in order to support
157 iDNS. PR#6635 [Tony Finch]
159 *) Cleanup the byterange filter to use the apr_brigade_partition
160 and apr_bucket_copy functions. This removes a lot of very messy
161 code, and hopefully makes this filter more stable.
164 *) Remove AddModule and ClearModuleList directives. Both of these
165 directives were used to ensure that modules could be enabled
166 in the correct order. That requirement is now gone, because
167 we use hooks to ensure that modules are in the correct order.
170 *) When SuExec is specified, we need to add it to the list of
171 targets to be built. If we don't, then any changes to the
172 configuration won't affect SuExec, unless 'make suexec' is
173 specifically run. [Ryan Bloom]
175 *) Cleaned out open_file from mod_file_cache, as apr now accepts
176 the APR_XTHREAD argument to open a file for consumption by
177 parallel threads on win32. [William Rowe]
179 *) Correct a bug in determining when we follow symlinks. The code
180 expected a stat -1 result, not an apr_status_t positive error.
181 Also check if the APR_FINFO_USER fields are valid before we
182 follow the link. [William Rowe]
184 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
185 mpm_common.c. These functions are only valid on some platforms,
186 so they should not be in the main-line code. [Ryan Bloom]
188 *) Remove ap_chdir_file(). This function is not thread-safe,
189 and nobody is currently using it. [Ryan Bloom]
191 *) Do not try to run make depend if there are no .c files in the
192 current directory, doing so makes `make depend` fail.
195 *) Update highperformance.conf to work with either prefork or
196 pthreads mpms. [Greg Ames]
198 *) Stop checking to see if this is a pipelined request if we know
199 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
200 This keeps us from making an extra read call when serving a 1.0
201 request. [Ryan Bloom and Greg Stein]
203 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
204 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
205 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
207 *) Fix the RFC number mentioned when complaining about a missing
208 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
210 *) Fix an endless loop in ab which occurred when ab was posting
211 and the server dropped the connection unexpectedly.
214 *) Fix a segfault while handling request bodies in ap_http_filter().
215 This problem has been seen with mod_dav usage as well as with
216 requests where the body was just being discarded. [Jeff Trawick]
218 *) Some adjustment on the handling and automatic setting (via
219 hints.m4) of various compilation flags (eg: CFLAGS). Also,
220 add the capability to specify flags (NOTEST_CFLAGS and
221 NOTEST_LDFLAGS) which are used to compile Apache, but
222 not used during the configuration process. Useful for
223 flags like "-Werror". [Jim Jagielski]
225 *) Stop using environment variables to force debug mode or
226 no detach. We now use the -D command line argument to
227 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
228 [Greg Stein, Ryan Bloom]
230 *) Change handlers to use hooks. [Ben Laurie]
232 *) Stop returning copies of filenames from both apr_file_t and
233 apr_dir_t. We pstrdup the filenames that we store in the
234 actual structures, so we don't need to pstrdup the strings again.
237 *) mod_cgi: Fix some problems where the wrong error value was being
238 traced. [Jeff Trawick]
240 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
243 *) Add generic hooks. [Ben Laurie]
245 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
247 *) Fix a segfault caused by mod_ext_filter when the external filter
248 program does not exist. [Jeff Trawick]
250 *) Fix an output truncation error when on an HTTP >= 1.0 request an
251 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
252 was served through mod_charset_lite (or anything else that would
253 create a transient bucket in this size range). ap_bucket_make_heap()
254 silently failed (fixed), transient_setaside() discovered it, but
255 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
257 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
258 is that some browsers send extra lines at the end of POST requests, and
259 we don't want to delay sending data back to the user just because the
260 browser isn't well behaved. [Ryan Bloom]
262 *) Get SuEXEC working again. We can't send absolute paths to suExec
263 because it refuses to execute those programs. SuEXEC also wasn't
264 always recognizing configuration changes made using the autoconf
267 *) Allow the buildconf process to find the config.m4 files in the correct
268 order. Basically, we can now name config.m4 files as config\d\d.m4,
269 and we will sort them correctly when inserting them into the build
270 process. [Ryan Bloom]
272 *) Get mod_cgid to use apr calls for creating the actual CGI process.
273 This also allows mod_cgid to use ap_os_create_priviledged_process,
274 thus allowing for SuExec execution from mod_cgid. Currently, we do
275 not support everything that standard SuExec supports, but at least
276 it works minimally now. [Ryan Bloom]
278 *) Allow SuExec to be configured from the ./configure command line.
281 *) Update some of the docs in README and INSTALL to reflect some of
282 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
284 *) If we get EAGAIN returned from the call to apr_sendfile, then we
285 need to call sendfile again. This gets us serving large files
286 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
288 *) Get the support programs building cleanly again.
289 [Cliff Woolley <cliffwoolley@yahoo.com>]
291 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
292 current directory logic now backs up over bin/ to determine the
293 server root from the Apache.exe path.
295 *) Apache/Win32 now follows the standard conventions of mod_foo.so
296 loadable modules, dynamic libs are all named libfoo.dll, and the
297 makefile.win populates the include, lib and libexec directories.
299 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
300 Apache gets IPv6 listening sockets by default. Additionally, the
301 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
302 numeric address strings (e.g., "Listen [fe80::1]:8080").
305 *) Modify the install directory layout. Modules are now installed in
306 modules/. Shared libraries should be installed in libraries/, but
307 we don't have any of those on Unix yet. All install directories
308 are modifyable at configure time. [Ryan Bloom]
310 *) Install all header files in the same directory on Unix. [Ryan Bloom]
312 *) Get the functions in server/linked into the server, regardless of
313 which modules linked into the server. This uses the same hack
314 for Apache that we use for APR and apr-util to ensure all of the
315 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
316 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
317 the scripts a bit easier.
320 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
321 on the query, and remove IPv4 dependencies. [Jeff Trawick]
323 *) Get all of the auth modules to the point that they will install and
324 be loadable into the server. Our new build/install mechanism expects
325 that all modules will have a common name format. The auth modules
326 didn't use that format, so we didn't install them properly.
329 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
330 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
332 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
334 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
335 after the end of the response. [Ryan Bloom]
337 *) Get byterange requests working with responses that do not have a
338 content-length. Because of the way byterange requests work, we have to
339 have all of the data before we can actually do the byterange, so we
340 can compute the content-length in the byterange filter.
343 *) Get exe CGI's working again on Windows.
346 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
347 they keep track of whether or not their post config hook has been
348 called before. Instead of a static variable (which is replaced when
349 the DSO is loaded a second time), use userdata in the process pool.
352 Changes with Apache 2.0a9
354 *) Win32 now requires perl to complete the final install step for users
355 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
356 and installs the conf, htdocs and htdocs/manual directories.
359 *) Make mod_include use a hash table to associate directive tags with
360 functions. This allows modules to implement their own SSI tags easily.
361 The idea is simple enough, a module can insert it's own tag and function
362 combination into a hash table provided by mod_include. While mod_include
363 parses an SSI file, when it encounters a tag in the file, it does a
364 hash lookup to find the function that implements that tag, and passes
365 all of the relevant data to the function. That function is then
366 responsible for processing the tag and handing the remaining data back
367 to mod_include for further processing.
368 [Paul J. Reder <rederpj@raleigh.ibm.com>]
370 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
371 fewer parameters: the local and remote socket addresses were removed
372 from the parameter list because all required information is available
373 via the APR socket. [Jeff Trawick]
375 *) Distribution directory structure reorganized to reflect a
376 normal source distribution with external install targets.
379 *) The MPMs that need multiple segments of shared memory now create
380 two apr_shmem_t variables, one for each shared memory allocation.
381 the problem is that we can't determine how much memory will be required
382 for shared memory allocations once we try to allocate more than one
383 variable. The MM code automatically aligns the shared memory allocations,
384 so we end up needing to pad the amount of shared memory we want based
385 on how many variables will be allocated out of the shared memory segment.
386 It is just easier to create a second apr_shmem_t variable, and two
390 *) Cleanup the export list a bit. This creates a single unified list of
391 functions exported by APR. The export list is generated at configure
392 time, and that list is then used to generate the exports.c file.
393 Because of the way the export list is generated, we only export those
394 functions that are valid on the platform we are building on.
397 *) Enable logging the cookie with mod_log_config
398 [Sander van Zoest <sander@covalent.net>]
400 *) Fix a segfault in mod_info when it reaches the end of the configuration.
403 *) Added lib/aputil/ as a placeholder for utility functions which are not
404 specific to the Apache HTTP Server (but do not make sense with APR).
405 The first utility is "apu_dbm": a set of functions to work with DBM
406 files. This first version can be compiled for SDBM or GDBM databases.
409 *) Complete re-write of mod_include. This makes mod_include a filter that
410 uses buckets directly. This has now served the FAQ correctly.
411 [Paul Reder <rederpj@raleigh.ibm.com>]
413 *) Allow modules to specify the first filter in a sub_request when
414 making the sub_request. This keeps modules from having to change the
415 output_filter immediately after creating the sub-request, and therefore
416 skip the sub_req_output_filter. [Ryan Bloom]
418 *) Update ab to accept URLs with IPv6 literal address strings (in the
419 format described in RFC 2732), and to build Host header fields in
420 the same format. This allows IPv6 literal address strings to be
421 used with ab. This support has been tested against Apache 1.3 with
422 the KAME patch, but Apache 2.0 does not yet work with this format
423 of the Host header field. [Jeff Trawick]
425 *) Accomodate an out-of-space condition in the piped logs and the
426 rotatelogs.c code, and no longer churn log processes for this
427 condition. [Victor J. Orlikowski]
429 *) Add support for partial writes with apr_sendfile() to core_output_filter.
432 Changes with Apache 2.0a8
434 *) Add a directive to mod_mime so that filters can be associated with
438 *) Get multi-views working again. We were setting the path_info
439 field incorrectly if we couldn't find the specified file.
442 *) Fix 304 processing. The core should never try to send the headers
443 down the filter stack. Always, just setup the table in the request
444 record, and let the header filter convert it to data that is ready
448 *) More fixes for the proxy. There are still bugs in the proxy code,
449 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
453 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
456 *) APR: Add new apr_getopt_long function to handle long options.
457 [B. W. Fitzpatrick <fitz@red-bean.com>]
459 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
460 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
461 hostname resolution/address string parsing and building
462 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
463 of one of the apr_sockaddr_t structures for a socket. Change
464 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
466 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
467 I have proxied pages with it, cleanup will commence soon.
470 *) Make the proxy work with filters. This isn't perfect, because we
471 aren't dealing with the headers properly. [Ryan Bloom]
473 *) Do not send a content-length iff the C-L is 0 and this is a head
474 request. [Ryan Bloom]
476 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
477 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
479 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
481 *) Get the default_handler to stop trying to deal with HEAD requests.
482 The idea is to let the content-length filter compute the C-L before
483 we try to send the data. If we can get the C-L correctly, then we
484 should send it in the HEAD response.
487 *) The Header filter can now determine if a body should be sent based
488 on r->header_only. The general idea of this is that if we delay
489 deciding to send the body, then we might be able to compute the
490 content-length correctly, which will help caching proxies to cache
491 our data better. Any handler that doesn't want to try to compute
492 the content-length can just send an EOS bucket without data and
493 everything will just work.
496 *) Add the referer to the error log if one is available.
497 [Markus Gyger <mgyger@itr.ch>]
499 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
500 change, the root of the configuration tree has been exposed to modules
502 [Ryan Morgan <rmorgan@covalent.net>]
504 *) Get the core_output_filter to use the bucket interface directly.
505 This keeps us from calling the content-length filter multiple times
506 for a simple static request.
509 *) We are sending the content-type correctly now.
510 [Ryan Bloom and Will Rowe]
512 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
513 a bogus bytes-sent value when the only thing being sent was trailers
514 and writev() returned an error (or EAGAIN). [Jeff Trawick]
516 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
517 hints file to determine which platforms define
518 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
521 *) APR: add apr_get_home_directory() [Jeff Trawick]
523 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
525 *) Not all platforms have INADDR_NONE defined by default. Apache
526 used to make this check and define INADDR_NONE if appropriate,
527 but APR needs the check too, and I suspect other applications will
528 as well. APR now defines APR_INADDR_NONE, which is always a valid
529 value on all platforms.
530 [Branko Èibej <brane@xbc.nu>]
532 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
533 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
535 *) Relax the syntax checking of Host: headers in order to support
536 iDNS. PR#6635 [Tony Finch]
538 *) When reading from file buckets we convert to an MMAP if it makes
539 sense. This also simplifies the default handler because the
540 default handler no longer needs to try to create MMAPs.
543 *) BUFF has been removed from the main server. The BUFF code will remain
544 in the code until it has been purged from the proxy module as well.
547 *) Byteranges have been completely re-written to be a filter. This
548 has been tested, and I believe it is working correctly, but it could
549 doesn't work for the Adobe Acrobat plug-in. The output almost matches
550 the output from 1.3, the only difference being that 1.3 includes
551 a content-length in the response, and this does not.
554 *) APR read/write functions and bucket read functions now operate
555 on unsigned integers, instead of signed ones. It doesn't make
556 any sense to use signed ints, because we return the error codes,
557 so if we have an error we should report 0 bytes read or written.
560 *) Always compute the content length, whether it is sent or not.
561 The reason for this, is that it allows us to correctly report
562 the bytes_sent when logging the request. This also simplifies
563 content-length filter a bit, and fixes the actual byte-reporing
564 code in mod_log_config.c
567 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
568 it says, because it was only used by EOS and FLUSH buckets. Since
569 neither of those are required at the end of a brigade, this was
570 really signifying FLUSH_THE_DATA, but that can be determined better
571 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
572 buckets now return a length of 0, which is actually the amount of data
573 read, so they make more sense.
576 *) Allow the core_output_filter to save some data past the end of a
577 request. If we get an EOS bucket, we only send the data if it
578 makes sense to send it. This allows us to pipeline request
579 responses. As a part of this, we also need to allocate mmap
580 buckets out of the connection pool, not the request pool. This
581 allows the mmap to outlive the request.
584 *) Make blocking and non-blocking bucket reads work correctly for
585 sockets and pipes. These are the only bucket types that should
586 have non-blocking reads, because the other bucket types should
587 ALWAYS be able to return something immediately.
590 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
591 server, but use Ctrl+Break to initiate a graceful restart
592 instead of duplicating behavior. [John Sterling]
594 *) Patch mod_autoindex to set the Last-Modified header based on
595 the directory's mtime, and add the ETag header. [William Rowe]
597 *) Merge the 1.3 patch to add support for logging query string in
598 such a way that "%m %U%q %H" is the same as "%r".
601 *) Port three log methods from mod_log_config 1.3 to 2.0:
602 CLF compliant '-' byte count, method and protocol.
605 *) Add a new LogFormat directive, %c, that will log connection
606 status at the end of the response as follows:
607 'X' - connection aborted before the response completed.
608 '+' - connection may be kept-alive by the server.
609 '-' - connection will be closed by the server.
612 *) Expand APR for WinNT to fully accept and return utf-8 encoded
613 Unicode file names and paths for Win32, and tag the Content-Type
614 from mod_autoindex to reflect that charset if the the feature
615 macro APR_HAS_UNICODE_FS is true. [William Rowe]
617 *) Compute the content length (and add appropriate header field) for
618 the response when no content length is available and we can't use
619 chunked encoding. [Jeff Trawick]
621 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
622 so that content input filters get dechunked data when using
623 the default handler. Also removed REQUEST_CHUNKED_PASS.
626 *) Add mod_ext_filter as an experimental module. This module allows
627 the administrator to use external programs as filters. Currently,
628 only filtering of output is supported. [Jeff Trawick]
630 *) Most Apache functions work on EBCDIC machines again, as protocol
631 data is now translated (again). [Jeff Trawick]
633 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
634 the EBCDIC support. They are noops on ASCII machines, so this
635 type of translation doesn't have to be surrounded by #ifdef
636 CHARSET_EBCDIC. [Jeff Trawick]
638 *) Fix mod_include. tag commands work again, and the server will
639 send the FAQ again. This also allows mod_include to set aside
640 buckets that include partial buckets.
641 [Ryan Bloom and David Reid]
643 *) Add suexec support back. [Manoj Kasichainula]
645 *) Lingering close now uses the socket directly instead of using
646 BUFF. This has been tested, but since all we can tell is that it
647 doesn't fail, this needs to be really hacked on.
650 *) Allow filters to modify headers and have those headers be sent to
651 the client. The idea is that we have an http_header filter that
652 actually sends the headers to the network. This removes the need
653 for the BUFF to send headers.
656 *) Charset translation: mod_charset_lite handles translation of
657 request bodies. Get rid of the xlate version of ap_md5_digest()
658 since we don't compute digests of filtered (e.g., translated)
659 response bodies this way anymore. (Note that we don't do it at
660 all at the present; somebody needs to write a filter to do so.)
663 *) Input filters and ap_get_brigade() now have a input mode parameter
664 (blocking, non-blocking, peek) instead of a length parameter.
667 *) Update the mime.types file to the registered media types as
668 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
671 *) Namespace protect some macros declared in ap_config.h
674 *) Support HTTP header line folding with input filtering.
677 *) Mod_include works again. This should still be re-written, but at
678 least now we can serve an SHTML page again.
681 *) Begin to remove BUFF from the core. Currently, we keep a pointer
682 to both the BUFF and the socket in the conn_rec. Functions that
683 want to use the BUFF can, functions that want to use the socket,
684 can. They point to the same place.
687 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
688 [Tomas "Ögren" <stric@ing.umu.se>]
690 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
691 associated pool goes away. (APR pipes on OS/2 were already had this
692 logic.) This resolvs a fatal file descriptor leak with CGIs.
695 *) The final line of the config file was not being read if there was
696 no \n at the end of it. This was caused by apr_fgets returning
697 APR_EOF even though we had read valid data. This is solved by
698 making cfg_getline check the buff that was returned from apr_fgets.
699 If apr_fgets return APR_EOF, but there was data in the buf, then we
700 return the buf, otherwise we return NULL.
703 *) Piped logs work again in the 2.0 series.
706 *) Restore functionality broken by the mod_rewrite security fix:
707 rewrite map lookup keys and default values are now expanded
708 so that the lookup can depend on the requested URI etc.
709 PR #6671 [Tony Finch]
711 *) Tighten up the syntax checking of Host: headers to fix a
712 security bug in some mass virtual hosting configurations
713 that can allow a remote attacker to retrieve some files
714 on the system that should be inaccessible. [Tony Finch]
716 *) Add a pool bucket type. This bucket is used for data allocated out
717 of a pool. If the pool is cleaned before the bucket is destroyed, then
718 the data is converted to a heap bucket, allowing it to survive the
722 *) Add a flush bucket. This allows modules to signal that the filters
723 should all flush whatever data they currently have. There is no way
724 to actually force them to do this, so if a filter ignores this bucket,
725 that's life, but at least we can try with this.
728 *) Add an output filter for sub-requests. This filter just strips the
729 EOS bucket so that we don't confuse the main request's core output
730 filter by sending multiple EOS buckets. This change also makes sub
731 requests start to send EOS buckets when they are finished.
734 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
735 makes ap_bucket_destroy a return void, which is okay because it
736 used to always return APR_SUCCESS, and nobody ever checked its
738 [Cliff Woolley <cliffwoolley@yahoo.com>]
740 *) Remove the index into the bucket-type table from the buckets
741 structure. This has now been replaced with a pointer to the
742 bucket_type. Also add some macros to test the bucket-type.
745 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
746 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
747 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
748 All _VAR_ flavors changes to _DATA to be absolutely clear.
751 *) Add support for /, //, //servername and //server/sharename
752 parsing of <Directory> blocks under Win32 and OS2.
753 [Tim Costello, William Rowe, Brian Harvard]
755 *) Remove the function pointers from the ap_bucket type. They have been
756 replaced with a global table. Modules are allowed to register bucket
757 types and use then use those buckets.
760 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
761 once we finish writing the request body to the cgi child process;
762 otherwise, the client doesn't hit EOF on stdin. Small request bodies
763 worked without this change (for reasons I don't understand), but large
764 ones didn't. [Jeff Trawick]
766 *) Remove file bucket specific information from the ap_bucket type.
767 This has been moved to a file_bucket specific type that hangs off
768 the data pointer in the ap_bucket type.
771 *) Input filtering now has a third argument. This is the amount of data
772 to read from lower filters. This argument can be -1, 0, or a positive
773 number. -1 means give me all the data you have, I'll deal with it and
774 let you know if I need more. 0 means give me one line and one line
775 only. A positive number means I want no more than this much data.
777 Currently, only 0 and a positive number are implemented. This allows
778 us to remove the remaining field from the conn_rec structure, which
782 *) Big cleanup of the input filtering. The goal is that http_filter
783 understands two conditions, headers and body. It knows where it is
784 based on c->remaining. If c->remaining is 0, then we are in headers,
785 and http_filter returns a line at a time. If it is not 0, then we are
786 in body, and http_filter returns raw data, but only up to c->remaining
787 bytes. It can return less, but never more.
788 [Greg Ames, Ryan Bloom, Jeff Trawick]
790 *) mod_cgi: Write all of the request body to the child, not just what
791 the kernel would accept on the first write. [Jeff Trawick]
793 *) Back out the change that moved the brigade from the core_output_filters
794 ctx to the conn_rec. Since all requests over a given connection
795 go through the same core_output_filter, the ctx pointer has the
799 *) Fix another bug in the send_the_file() read/write loop. A partial
800 send by apr_send would cause unsent data in the read buffer to
801 get clobbered. Complete making send_the_file handle partial
802 writes to the network.
805 *) Fix a couple of type fixes to allow compilation on AIX again
806 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
808 *) Fix bug in send_the_file() which causes offset to be ignored
809 if there are no headers to send.
812 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
813 filter. Useful for supporting Windows 9* with a binary
814 compiled on Windows NT.
817 Changes with Apache 2.0a7
819 *) Reimplement core_output_filter to buffer/save bucket brigades
820 across multiple calls to the core_filter. The brigade will be
821 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
822 thresholds are hit or the EOS bucket is received.
825 *) Create experimental filter (buffer_filter) that coalesces bytes
826 into one large buffer before invoking the next filter in the
827 chain. This filter is particularly useful with the current
828 implementation of mod_autoindex when it inserted above the
829 chunk_filter. mod_autoindex generates a lot of brigades that
830 containing buckets holding just a few bytes each. The
831 buffer_filter coalesces these buckets into a single large bucket.
834 *) Add apr_sendfile() support into the core_output_filter.
837 *) Add apr_sendv() support into the core_output_filter.
840 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
841 [Mike Abbott <mja@sgi.com>]
843 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
844 make much sense, because Apache uses buckets instead of BUFFs now.
847 *) send_the_file now falls back to a read/write loop on platforms that
848 do not have sendfile.
849 [Ryan Bloom and Brian Havard]
851 *) Install apachectl correctly, and substitute the proper values so
852 that it works again. [Ryan Bloom]
854 *) Better(??) handle platforms that lack sendfile().
857 *) APR now has UUID generation/formatting/parsing support.
860 *) Begin the http_filter. This is an input filter that understands
861 the absolute basic amount required to parse an HTTP Request. The
862 goal is to be able to split headers from request body before passing
863 the data back to the other filters.
866 *) Bring forward from 1.3.13 the config directory implementation
869 *) install apxs if it is created
872 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
873 conversions. [William Rowe]
875 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
876 ap_add_output_filter(). [Jeff Trawick]
878 *) Multiple build and configuration fixes
881 -add datadir and localstatedir substitutions
883 -fix logfilename misspelling
884 -fix evaluation of installation dir variables and
885 -replace $foobar by $(foobar) to be usefull in the makefile
889 -add rules for cross-compiling in rules.mk. Okay, rule to check for
890 $CC_FOR_BUILD is still missing
891 -use CHECK_TOOL instead of CHECK_PROG for ranlib
892 -add missing "AR=@AR@" to severaly Makefile.in's
893 -cache result for "struct rlimit"
894 -compile all helper programs with native and cross compiler
895 and use the native version to generate header file
896 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
898 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
900 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
902 *) Fix a bug where a client which only sends \n to delimit header
903 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
904 message. Start working on ebcdic co-existance with input
906 [William Rowe, Greg Ames]
908 *) If mod_so is enabled in the server always create libexec, even
909 if there are no modules installed in this directory. This is a
910 requirement for APXS to work correctly.
913 *) Connection oriented output filters are now stored in the
914 conn_rec instead of the request_rec. This allows us to add the
915 output filter in the pre-connection phase instead of the
916 post_read_request phase, which keeps us from trying to write an
917 error page before we have a filter to write to the network.
918 [Ryan Bloom, Jeff Trawick, and Greg Ames]
920 *) Cleaning up an mmap bucket no longer deletes the mmap. An
921 mmap can be used across multiple buckets (default_handler with
922 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
923 the mmap itself can't be associated with the bucket.
926 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
929 *) Radical surgery to improve mod_isapi support under Win32.
930 Includes a number of newer ServerSupportFunction calls, support
931 for ReadClient (in order to retrieve POSTs greater than 48KB),
932 and general bug fixes to more reliably load ISAPI .dll's and
933 prevent leaking handle resources. Note: There are still
934 discrepancies between IIS's and Apache's ServerVariables, and
935 async calls are still not supported. Additional warnings are
936 logged to facilitate debugging of unsupported ISAPI calls.
939 *) Add input filtering to Apache. The basic idea for the input
940 filters is the same as the ideas for output filters. The biggest
941 difference is that instead of calling ap_pass_brigade, ap_get_brigade
942 should be called, and the order of execution for the filter itself is
943 different. When writing an output filter, a brigade is passed in,
944 and filters operate directly on that brigade, when done, they call
945 ap_pass_brigade. Input filters are the exact opposite. Because input
946 is not a push operation, filters first call ap_get_brigade. When this
947 function returns, the input filter will be left with a valid brigade.
948 The input filter should then operate on the brigade, and return.
951 *) Fix building on BSD/OS using its native make. The build system
952 falls back to the BSD .include directive on that host platform.
955 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
956 SHA1 and plaintext password encodings. Make feature tests a
957 bit more flexible. [William Rowe]
959 *) Charset translation: mod_charset_lite handles output content
960 translation in a filter. mod_charset_lite no longer ignores
961 subrequests. A bunch of cruft related to BUFF's support for
962 translating request and response bodies was removed.
965 *) Move the addition of the CORE filter to the post_read_request
966 hook in http_core.c. This removes the need to add the filter in
967 multiple places and allows for an SSL module to be added much
968 simpler. [Ryan Bloom]
970 *) Fix a security problem that affects certain configurations of
971 mod_rewrite. If the result of a RewriteRule is a filename that
972 contains expansion specifiers, especially regexp backreferences
973 $0..$9 and %0..%9, then it may be possible for an attacker to
974 access any file on the web server. [Tony Finch]
976 *) Fix a bug where errors that are detected during early request parsing
977 don't produce visible HTTP error messages at the browser, because
978 the core_filter wasn't present. [Greg Ames]
980 *) Provide apr_socklen_t as a portability aid.
981 [Victor J. Orlikowski]
983 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
984 as well as a comment arg to the add, adduser and update cmds.
985 update allows the user to clear or preserve pw/groups/comment.
986 Fixed a bug in dbmmanage that prevented the check option from
987 parsing a password followed by :group... text. Corrected the
988 seed calcualation for Win32 systems, and added -lsdbm support.
991 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
994 *) Avoid a segfault when parsing .htaccess files. An
995 uninitialized tree pointer was passed to ap_build_config().
998 *) Change the way that inet_addr & inet_network are checked for
999 in APR's configure process to allow BeOS BONE to correctly
1000 find them. With this change BeOS BONE now builds from source
1001 with no problems. [David Reid]
1003 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
1004 the end of the parameters to execve() was stored in the wrong
1005 location, overlaying the storage beyond the newargs[] array and
1006 also passing uninitialized storage to execve(), which would
1007 sometimes fail with EFAULT. [Jeff Trawick]
1009 *) Fix a bug parsing configuration file containers. With a sequence
1010 like this in the config file
1012 <IfModule mod_kilroy.c>
1015 <IfModule mod_lovejoy.c>
1020 the second container would be terminated at the blank line due to
1021 sediment in the buffer from reading the prior </IfModule> and an
1022 error message would be generated for the real </IfModule> for the
1023 second container. Also due to this problem, any two characters
1024 could be used for "</" in the close of a container.
1027 *) ap_add_filter prototype changed to remove the ctx pointer. The
1028 pointer still remains in the filter structure, but it can not be
1029 a part of the ap_add_filter prototype. The reason is that when
1030 the core uses AddFilter to add a filter to the stack it doesn't
1031 know how to allocate the ctx pointer, or even how much memory should
1032 be allocated. The filters will have to be responsible for allocating
1033 the ctx memory when they need it.
1036 *) Add an AddFilter directive. This directive takes a list of filters
1037 that should be activated for the requested resource.
1040 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
1041 some other platforms). [Jeff Trawick]
1043 *) Modify mod_include to be a filter. Currently, it has only been tested
1044 on actual files, but it should work for CGI scripts too.
1047 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
1048 writes. apr_flush() for Unix: handle interrupted writes.
1051 *) NameVirtualHost can now take "*" as an argument instead of
1052 an IP address. This allows you to create a purely name-based
1053 virtual hosting server that does not have any IP addresses in
1054 the configuration file and which ignores the local address
1055 of any connections. PR #5595, PR #4455 [Tony Finch]
1057 *) Fix some compile warnings in mod_mmap_static.c
1058 [Mike Abbott <mja@sgi.com>]
1060 *) Fix chunking problem with CGI scripts. The general problem was that
1061 the CGI modules were adding an EOS bucket and then the core added an
1062 EOS bucket. The chunking filter finalizes the chunked response when it
1063 encounters an EOS bucket. Because two EOS buckets were sent, we
1064 finalized the response twice. The fix is to make sure we only send one
1065 EOS, by utilizing a flag in the request_rec.
1068 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
1069 and Win32. Previously, the first read from an apr_file_t set up via
1070 apr_put_os_file() would return a '\0'. [Jeff Trawick]
1072 *) Mod_cgid now creates a single element bucket brigade, with a pipe
1073 bucket, instead of using BUFF's and ap_r*.
1076 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
1077 [Mike Abbott <mja@sgi.com>]
1079 *) Remove ap_bopenf from buff code. This required modifying the file_cache
1080 code to use APR file's directly instead of going through BUFFs.
1083 *) Fix compile break on some platforms for mod_mime_magic.c
1084 [John K. Sterling <sterling@covalent.net>]
1086 *) Fix merging of AddDefaultCharset directive.
1087 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
1089 *) Minor revamp of the rlimit sections of code. We now test
1090 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
1091 is now "available" even if the platform doesn't support
1092 the rlimit family (it's just a noop though). [Jim Jagielski]
1094 *) Migrate the pre-selection of which MPM to use for specific
1095 platforms to hints.m4, which contains (or should contain)
1096 all platform specific "hints". [Jim Jagielski]
1098 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
1101 *) Add tables with non-string/binary values to APR.
1104 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
1107 *) Update PCRE to version 3.2. [Ryan Bloom]
1109 *) Change the way buckets' destroy functions are called so that
1110 they can be more directly used when changing the type of a
1111 bucket in place. [Tony Finch]
1113 *) Add generic support for reference-counting the resources used by
1114 buckets, and alter the HEAP and MMAP buckets to use it. Change
1115 the way buckets are initialised to support changing the type of
1116 buckets in place, and use it when setting aside TRANSIENT buckets.
1117 Change the implementation of TRANSIENT buckets so that it can be
1118 mostly shared with IMMORTAL buckets, which are now implemented.
1121 Changes with Apache 2.0a6
1123 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
1125 *) Add a chunking filter to Apache. This brings us one step closer
1126 to removing BUFF. [Ryan Bloom]
1128 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
1129 added to the stack is the last filter to be called. [Ryan Bloom]
1131 *) Apache 2.0 has been completely documented using Scandoc. The
1132 docs can be generated by running 'make docs'. [Ryan Bloom]
1134 *) Add filtered I/O to Apache. This is based on bucket brigades,
1135 Currently the buckets still use BUFF under the covers, but that
1136 should change quickly. The only currently written filter is the
1137 core filter which just calls ap_bwrite. [The Apache Group]
1139 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
1140 built with thread support. [Jeff Trawick]
1142 *) Abort configuration if --with-layout was specified and there's
1143 no layout definition file. [Ken Coar]
1145 *) Add support for '--with-port=n' option to configure. [Ken Coar]
1147 *) Add support for extension methods for the Allow response header
1148 field, and an API routine for accessing r->allowed and the
1149 list of extension methods in a unified manner. [Ken Coar]
1151 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
1152 [Rob Simonson <simo@us.ibm.com>]
1154 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
1155 APACHE_XLATE builds. [Jeff Trawick]
1157 *) A configuration file parsing problem was fixed. When the
1158 configuration file started with an IfModule/IfDefine container,
1159 only the last statement in the container would be retained.
1162 Changes with Apache 2.0a5
1164 *) Perchild is serving pages after passing them to different child
1165 processes. There are still a lot of bugs, but this does work. I
1166 have made requests against the same installation of Apache, and had
1167 different servers use different user IDs to serve the responses.
1168 This change moves to using socketpair instead of an AF_UNIX socket.
1171 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
1172 It can't seem to pass between child processes yet, but I think we
1173 are closer now than before. This moves us back to using Unix
1174 Domain Sockets. [Ryan Bloom]
1176 *) libapr functions and types renamed with apr_ prefix.
1177 #include "apr_compat.h" for 1.3.x backwards compat
1180 *) Fix problems with APR sockaddr handling on Win32. It didn't always
1181 return the right information on the local socket address.
1182 [Gregory Nicholls <gnicholls@level8.com>]
1184 *) ap_recv() on Win32: Set bytes-read to 0 on error.
1185 [Gregory Nicholls <gnicholls@level8.com>]
1187 *) Add an option to not detach from the controlling terminal without
1188 going into single process mode. This allows for much easier
1189 debugging of the process startup code. [Ryan Bloom]
1191 *) ab: don't use perror() to report the failure of an APR function.
1194 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
1195 scoreboard on graceful restarts.
1198 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
1199 An invalid ap_proc_t was passed to ap_create_process().
1202 *) Allow modules to register filters. Those filters are still
1203 never called, but this is a step in the right direction.
1204 [Ryan Bloom and Greg Stein]
1206 *) Register the mod_cgid daemon process for cleanup so that it is
1207 killed at termination if it does not die when the parent gets
1208 SIGTERM. This change is to fix occasional problems where the
1209 process stays around. Bugs in similar logic in mod_rewrite and
1210 mod_include were also fixed. [Jeff Trawick]
1212 *) Fix a bug in the time handling. Basically, we were imploding a time
1213 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
1214 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
1215 uses those two fields to adjust the time value. Because of the HTTP
1216 spec, both of those values can be zero'ed out safely. This fixes
1217 the bug correctly. [Ryan Bloom]
1219 *) Fix a couple of place in the Windows code where the wrong error
1220 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
1222 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
1224 *) Added the APR_EOL_STR macro for platform dependent differences in
1225 logfiles and other raw text (such as all APR files). Fixes logfiles
1226 not terminated with cr/lf sequences in Win32. [William Rowe]
1228 *) Move all strings functions in APR to src/lib/apr/strings and create
1229 apr_strings.h for the prototypes. [Ryan Bloom]
1231 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
1232 to repeat the syscall until we stop getting EINTR. I noticed a
1233 related problem at termination (SIGTERM) on FreeBSD when using
1234 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
1235 implementation work properly with child init. Previously, ap_lock()
1236 was essentially a no-op because all children were using different
1237 locks and thus nobody ever blocked. [Jeff Trawick]
1239 *) The htdocs/ tree has been moved out of the CVS source tree into
1240 a separate area for easier development. This has NO EFFECT on
1241 end-users or Apache installations. [Ken Coar]
1243 *) Integrate the mod_dav module for WebDAV protocol handling. This
1244 adds the dav and dav_fs modules, the SDBM library, and additional
1245 XML handling utilities. [Greg Stein]
1247 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
1250 *) Update the lib/expat-lite/ library (bring forward changes from
1251 the Apache 1.3 repository). [Greg Stein]
1253 *) If sizeof(long long) == sizeof(long), then prefer long in APR
1254 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
1256 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
1257 machines where sendfile is detected, but nobody has written ap_sendfile.
1258 [Dave Hill <ddhill@zk3.dec.com>]
1260 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
1262 *) ab would start up more connections than needed, then quit when the
1263 desired number were finished. Also fixed a logic error involving
1264 ab keepalives. [Victor J. Orlikowski]
1266 *) WinNT: Implement non-blocking pipes with timeouts to communicate
1267 with CGIs. Apache 2.0a4 had non-blocking pipes but without
1268 timeouts (i.e, if a timeout was specified, the pipe reverted to
1269 a full blocking pipe). Now the behaviour is more in line with
1270 Unix non-blocking pipes.
1273 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
1274 cache open file handles along with accept socket reuse enables
1275 Apache 2.0 to serve non-keepalive requests for static files at
1276 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
1277 and Apache 2.0 will serve almost 1200 rps on my system).
1280 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
1281 supports two config directives, mmapfile (same behavious as
1282 mod_mmap_static) and cachefile. Use the cachefile directive
1283 to cache open file handles. This directive only works on systems
1284 that have implemented the ap_sendfile API. cachefile works today
1285 on Windows NT, but has not been tested on any flavors of Unix.
1288 *) Cleanup the configuration. With the last few changes the
1289 configuration process automatically:
1290 inherits information about how to build from APR. Allowing
1291 APR to inform Apache that it should or should not use -ldl
1293 Detects which mod_cgi should be used mod_cgi or mod_cgid,
1294 based on the threading model
1296 Apache calls APR's configure process before finishing it's
1297 configuration processing, allowing for more information flow
1302 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
1303 with non-zero argument makes the socket non-blocking. BeOS and
1304 OS/2 already worked this way. [Jeff Trawick]
1306 *) ap_close() now calls ap_flush() for buffered files, so write
1307 operations work a whole lot better on buffered files.
1310 *) Fix error messages issued from MPMs which explain where to change
1311 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
1314 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
1315 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
1316 now the way that the blocking state of a pipe is manipulated.
1317 ap_block_pipe() is gone. [Jeff Trawick]
1319 *) Correct the problem where the only local host name that the IP stack
1320 can discover are 'undotted' private names. If no fully qualified
1321 domain name can be identified, the default ServerName will be set to
1322 the machine's IP address string. A warning is always provided if the
1323 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
1325 *) Repair problems with config file processing which caused segfault
1326 at init when virtual hosts were defined and which caused ServerName to
1327 be ignored when there was no valid DNS setup. [Jeff Trawick]
1329 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
1331 *) Add ap_sendfile implementation for AIX
1332 [Victor J. Orlikowski]
1334 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
1335 apr_network_io.h, and apr_thread_proc.h.
1336 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
1338 *) Bring the allocation and pool debugging code back into a working
1339 state. This will need to be tested as so far it's only been used on
1342 *) Change configuration command setup to be properly typesafe when in
1343 maintainer mode. Note that this requires a compiler that can initialise
1344 unions. [Ben Laurie]
1346 *) Turn on buffering for config file reads. Part of this was to
1347 repair buffered I/O support in Unix and implement buffered
1348 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
1350 *) Win32: Fix problem where UTC offset was not being set correctly
1351 in the access log. Problem reported on news group by Jerry Baker.
1354 *) Fix segfault when reporting this type of syntax error:
1355 "</container> without matching <container> section", where
1356 container is VirtualHost or Directory or whatever.
1359 *) Prevent the source code for CGIs from being revealed when using
1360 mod_vhost_alias and the CGI directory is under the document root
1361 and a user makes a request like http://www.example.com//cgi-bin/cgi
1362 as reported in <news:960999105.344321@ernani.logica.co.uk>
1365 *) Add support for the new Beos NetwOrking Environment (BONE)
1368 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
1369 final input char is incomplete; ap_bwrite_xlate() now handles
1370 incomplete final input chars. [Jeff Trawick]
1372 *) Yet another update to saferead/halfduplex stuff -- need to ensure
1373 that a bhalfduplex call occurs before logging or else DNS and
1374 such can delay the last packet of the response. [Dean Gaudet]
1376 *) Some syscall reduction in APR on unix -- don't seek when setting
1377 up an mmap; and don't fcntl() more than once per socket.
1380 *) When mod_cgid is started as root, the cgi daemon now switches
1381 to the configured User/Group (like other httpd processes)
1382 instead of continuing as root. [Jeff Trawick]
1384 *) The prefork MPM now uses an APR lock for the accept() mutex.
1385 It has not been getting a lock at all recently. httpd -V now
1386 displays APR's selection of the lock mechanism instead of the
1387 symbols previously respected by prefork. [Jeff Trawick]
1389 *) Change the mmap() feature test to check only for existence.
1390 The previous check required features not used by Apache.
1393 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
1394 sometimes mangled. The len parm to accept() was not
1395 initialized, leading sometimes to an endless loop of failed
1396 accept() calls on OS/390 and anywhere else that failed the call
1397 if the len was negative. Use <sys/un.h> for struct sockaddr_un
1398 instead of declaring it ourselves to fix a compilation problem
1399 on Solaris. [Jeff Trawick]
1401 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
1403 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
1405 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
1407 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
1408 initialization if ALLOC_DEBUG is defined; no known symptom
1409 otherwise. [Jeff Trawick]
1411 *) Fix typo in configure script when checking for mod_so. bash
1412 doesn't seem to have a problem but /bin/sh on Solaris does.
1413 Symptom: "./configure: test: unknown operator =="
1416 *) Rebind the Win32 NT and 9x services control into the MPM.
1417 All console, WinNT SCM and Win9x pseudo-service control code is
1418 now wrapped within the WinNT MPM.
1421 *) Make a copy of getenv("PATH") before storing for later use. Some
1422 getenv() implementations use the same storage for successive calls.
1423 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
1425 *) Server Tokens work in 2.0 again. This also propogates the change
1426 to allow just the product name in the server string using
1430 Changes with Apache 2.0a4
1432 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
1433 won't need to call it. [Greg Ames, Jeff Trawick]
1435 *) Move pre_config hook call to between configuration read and config
1436 tree walk. This allows all modules to implement pre_config hooks
1437 and know that they will be called at an appropriate time.
1440 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
1443 *) Add pre-config hooks back to all modules.
1446 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
1447 ContentDigest enabled and we can't/don't mmap the file.
1450 *) We now report the correct line number for syntax errors in config
1451 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
1453 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
1454 related bugs, and changed shmem/locking to use apr API. Shared-mem
1455 is currently disabled, however, because of problems with graceful
1456 restarts. [Ronald Tschalär]
1458 *) Fix corruption of IFS variable in --with-module= handling.
1459 Depending on the user's shell or customization thereof, there
1460 would be errors generating ap_config_auto.h later in the configure
1461 procedure. [Jeff Trawick]
1463 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
1464 isn't used (as in 1.3), except that on Unix it is now logged via
1465 ap_log_rerror() instead of by the child having STDERR_FILENO refer
1466 to the error log. [Greg Ames, Jeff Trawick]
1468 *) Add '-D' argument processing for run time configuration defines.
1471 *) Organize http_main.c as independent code, such that no code or
1472 global data is exported from it. WIN32 will dynamically link it
1473 to the server core, so this will prevent mutual dependency.
1476 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
1477 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
1480 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
1481 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
1483 *) Add mod_charset_lite for configuring character set translation.
1486 *) Add '-n' option to htpasswd to make it print its user:pw record
1487 on stdout rather than having to frob a text file. [Ken Coar]
1489 *) Fix saferead. Basically, we flush the output buffer if a read on the
1493 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
1494 a conversion is single-byte only. [Jeff Trawick]
1496 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
1497 the BeOS 5.0 documentation says that shutdown doesn't work yet.
1500 *) Fix some minor errors where pid was being manipulated as an int
1501 instead of the portable pid_t. [Roy Fielding]
1503 *) Fix some error log prints that were printing the pointer to a
1504 structure rather than the pid within the structure.
1505 [Jeff Trawick, Roy Fielding]
1507 *) ab: Fix a command-line processing bug; track bad headers in
1508 err_response; support reading headers up to 2K.
1509 [Ask Bjoern Hansen <ask@valueclick.com>]
1511 *) Fix ap_resolve_env() so that it handles new function added in a prior
1512 alpha (see "Added the capability to do ${ENVVAR} constructs in the
1513 config file.") as well as the constructs used by mod_rewrite.
1514 [Paul Reder <rederpj@raleigh.ibm.com>]
1516 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
1518 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
1519 APR to perform translation, instead of accessing the hard-coded tables
1520 in 1.3's ebcdic.c. [Jeff Trawick]
1522 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
1525 *) Add the ability to hook into the config file reading phase. Basically
1526 if a directive is specified EXEC_ON_READ, then when that directive is
1527 read from the config file, the assocaited function is executed. This
1528 should only be used for those directives that must muck with HOW the
1529 server INTERPRETS the config. This should not be used for directives
1530 that re-order or replace items in the config tree. Those changes should
1531 be made in the pre-config step.
1534 *) Add mod_example to the build system.
1537 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
1538 byte character sets. [Jeff Trawick]
1540 *) Pick up various EBCDIC fixes from 1.3 (from Martin
1541 Kraemer and Oliver Reh originally according to the change log).
1544 *) Fix a couple of problems in RFC1413 support (controlled by the
1545 IdentityCheck directive). Apache did not build the request string
1546 properly and more importantly Apache would loop forever if the
1547 would-be ident server dropped the connection before sending a
1548 properly terminated response. [Jeff Trawick]
1550 *) apxs works in 2.0.
1553 *) Reliable piped logs work in 2.0.
1556 *) Introduce a hash table implementation into APR to be used for
1557 replacing tables and other random data structures in Apache.
1560 *) Add some more error reporting to htpasswd in the case of problems
1561 generating or accessing the temporary file. Also, pass in a
1562 buffer if the implementation knows how to use it (i.e., if L_tmpnam
1563 is defined). [Ken Coar]
1565 *) Configure creates config.nice now containing your configure
1566 options. Syntax: ./config.nice [--more-options]
1569 *) Fix various return code problems in APR on Win32. For most of
1570 these, APR was returning APR_EEXIST instead of GetLastError()/
1571 WSAGetLastError(). [Jeff Trawick]
1573 *) Make piped logs work again in version 2.0
1576 *) Add VPATH support to UNIX build system of Apache and APR.
1579 *) Fix ap_tokenize_to_argv to respect the const arguments that are
1583 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
1584 Patch submitted to author.
1587 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
1588 /sbin in PATH on FreeBSD (all submitted to rse previously)
1591 *) Fix building Pthread-based MPMs on OpenBSD
1592 [Sascha Schumann] PR#26
1594 *) Fix ap_readdir() problem on systems where d_name[] field in
1595 struct dirent is declared with only one byte. (This problem only
1596 affected multithreaded builds.) This caused a segfault during
1597 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
1598 least). [Jeff Trawick]
1600 *) Fix some make-portability problems on at least Tru64, Irix
1602 [Sascha Schumann] PR#18, PR#39
1604 *) Add ap_sigwait() to support old-style sigwait() on systems
1605 like OS/390 and UnixWare.
1608 *) Add POSIX-thread flags for more platforms.
1611 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
1612 (on Unix, at least) to handle resolver errors. Fix a bug in
1613 the definition of APR_ENOMEM so that ap_strerror() can spit
1614 out the correct error message for it.
1617 Changes with Apache 2.0a3
1619 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
1622 *) API: *HOOK* macros now have an AP_ prefix
1625 *) Win32: Eliminate redundant calls to initialize winsock.
1626 [Tim Costello <timcostello@ozemail.com.au>]
1628 *) Fix bugs initializing ungetchar for pipes.
1629 [Chia-liang Kao <clkao@CirX.ORG>]
1631 *) The ab program in the src/support directory is now portable using
1635 *) Support directory is being compiled when the server is built
1638 *) The configure option --with-program-name has been added to allow
1639 developers to rename the executable at configure time. This also
1640 changes the name of the config files to match the executable's name.
1643 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
1644 containing version numbers. [Martin Pool]
1646 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
1647 Unix; access_log and error_log now created with these perms; non-
1648 Unix is unaffected [Jeff Trawick]
1650 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
1651 Replaced more magic numbers with MD5_DIGESTSIZE.
1652 [William Rowe, Roy Fielding]
1654 *) Win32: Get mod_auth_digest compiling and added to the Windows
1655 build environment. Not tested and I'd be suprised if it
1656 actually works. [Bill Stoddard]
1658 *) Revamp the Win32 make environment. Makefiles have been removed and
1659 Apache.dsw created to bring together all the pieces. Create new file
1660 os/win32/BaseAddr.ref to define module base addresses (to prevent
1661 dll relocation at start-up).
1662 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
1664 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
1665 of the \015, \012, and \015\012 constants with macros.
1666 [Greg Ames <gregames@us.ibm.com>]
1668 *) Add ap_xlate_open() et al for translation of text between different
1669 character sets. The initial implementation requires iconv().
1672 *) More FAQs and answers from comp.infosystems.www.servers.unix.
1673 [Joshua Slive <slive@finance.commerce.ubc.ca>]
1675 *) CGI output is being timed out now.
1678 *) Fix the problem with dieing quietly. dupfile now takes a pool which
1679 is used by the new apr file. There is no reason to create a new file
1680 with the same lifetime as the original file.
1683 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
1684 module base addresses. This will help shooting seg faults
1685 in the field. [William Rowe <wrowe@lnd.com>]
1687 *) Update Apache on Windows documentation. Add new document
1688 describing how to compile Apache on Windows.
1689 [William Rowe <wrowe@lnd.com>]
1691 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
1692 microseconds instead of seconds. Some storage leaks and other
1693 minor bugs in related code were fixed. [Jeff Trawick]
1695 *) Win32: First cut at getting mod_isapi working under 2.0
1696 [William Rowe <wrowe@lnd.com>]
1698 *) First stab at getting mod_auth_digest working under 2.0
1699 quick change summary:
1700 - moved the random byte generation (ap_generate_random_bytes) into APR
1701 - now uses ap_time_t
1702 - compiles and runs on linux
1704 [Brian Martin <bmartin@penguincomputing.com>]
1706 *) Win32: Move the space stripping of physical service names
1707 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
1708 unresolved symbol. Add dependency checking to the
1709 CreateService call to ensure TCPIP and AFP (winsock) is started
1711 [William Rowe <wrowe@lnd.com>]
1713 *) Win32: Add code to perform latebinding on functions that may
1714 not exist on all levels of Windows where Apache runs. This
1715 is needed to allow Apache to start-up on Win95/98. All calls
1716 to non portable functions should be protected with
1717 ap_oslevel checks to prevent runtime segfaults.
1718 [William Rowe <wrowe@lnd.com>]
1720 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
1722 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
1724 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
1725 This addresses PR 1623. Still need to address timing out runaway
1726 CGI scripts. [Bill Stoddard]
1728 *) Win32: Make ap_stat Windows 95/98 friendly
1729 [William Rowe <wrowe@lnd.com>]
1731 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
1732 always fail. Need to initialise the dwOSVersionInfoSize member of the
1733 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
1736 The patch also enhances ap_get_oslevel (and the associated enum) to
1737 handle selected service packs for NT4, and adds recognition for
1738 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
1739 we can use ReadFileScatter and WriteFileGather in readwrite.c.
1740 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
1742 *) Get mod_rewrite building and running, and mod_status building for Win NT
1743 [Allan Edwards <ake@raleigh.ibm.com>]
1745 *) Patch to port mod_auth_db to the 2.0 api and also to support
1746 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
1747 2.7.7. It should work with version 1 as well but I haven't tested it.
1748 [Brian Martin <bmartin@penguincomputing.com>]
1750 *) Get APR DSO code working under Windows. Includes cross platform
1752 [Tim.Costello@BTFinancialgroup.com]
1754 *) Fix some of the Windows APR time functions.
1757 *) FAQ changes related to tidying up historical documents on the web site.
1758 [Joshua Slive <slive@finance.commerce.ubc.ca>]
1760 *) Move Windows DSO code into APR.
1763 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
1764 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
1765 at build time. At this point, the server will not compile on Windows because
1766 of the recent DSO commits. Fixing those next.
1767 [Bill Rowe & Bill Stoddard]
1769 *) Added error checking for file I/O APR routines.
1770 [Jon Travis <jtravis@covalent.net>]
1772 *) APR: Don't use the values of resolver error codes for the
1773 corresponding APR error codes. On Unix and Win32, return the
1774 proper APR error code after a resolver error. [Jeff Trawick]
1776 Changes with Apache 2.0a2
1778 *) Renamed the executable back to httpd on all platforms other
1782 *) Allow BeOS to survive restarts, log properly and a few
1783 small things it had problems with due to the way it setup
1784 users and groups. [David Reid]
1786 *) Get mod_rewrite working with APR locks
1787 [Paul Reder <rederpj@raleigh.ibm.com>]
1789 *) Actually remove the sempahore when the lock cleanup routine
1790 is called on BeOS. [David Reid]
1792 *) Clear hook registrations between reads of the config file.
1793 When DSOs are unloaded and re-loaded the old hook pointers may
1794 no longer be valid. This fix eliminates potential segfaults.
1795 [Allan Edwards <ake@raleigh.ibm.com>]
1797 *) Fix a problem with Sigfunc not being defined or bypassed
1798 if sigaction() wasn't found. [Jim Jagielski]
1800 *) Fix the locking mechanism on BSD variants. They now use fcntl
1801 locks. This allows the server to start and serve pages.
1804 *) First cut at getting the Win32 installer to work
1805 [William Rowe <wrowe@lnd.com>]
1807 *) Get htpasswd compiling under Windows
1808 [William Rowe <wrowe@lnd.com>]
1810 *) Change the log message for a bind() failure to show the
1811 interface and port number. [Jeff Trawick]
1813 *) Import the documentation from 1.3.12 and bring parts of it
1814 up-to-date with respect to the changes that have occurred
1818 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
1819 now logged correctly on BeOS.
1822 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
1823 Makefile.win includes the same user interface as the old
1825 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
1827 *) Win32 exec now uses COMSPEC environment string for command
1828 shell path resolution.
1829 [William Rowe <wrowe@lnd.com>] PR#3715
1831 *) Win32: ap_connect() was not returning correct error condition
1833 [Allen Prescott <allen@clanprescott.com>]
1835 *) Win32: ap_open() was broken on Win9x because an NT-specific
1836 flag was passed to CreateFile. ap_puts() added an unnecessary
1838 [Jeff Trawick <trawick@us.ibm.com>]
1840 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
1841 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
1842 confusing ee/et name and made all extensions language/dialect
1843 rather than country reflecting. Changed example files to
1844 explicit reflect the ISO charset and added a few common
1845 ones to the example config [dirkx]
1847 *) Extend external module capability. To use this, you call
1848 configure with --with-module=path/to/mod1,path/to/mod2,etc.
1851 *) Backported the various "default charset" fixes from 1.3.12,
1852 including the AddDefaultCharset directive. [Jim Jagielski]
1854 *) Added the capability to do ${ENVVAR} constructs in the
1855 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
1856 it does this on a line by line basis; i.e. if the envvar
1857 expands to something with spaces you have to protect it
1858 by adding quotes around it (Unless of course you expect it
1859 to contains more than one argument. Alternatively you
1860 can compile it on a per token basis; which is what people
1861 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
1862 hampers fancier hacks.
1863 [Dirk-Willem van Gulik]
1865 *) Changed the 'ErrorDocument' syntax in that it NO longer
1866 supports the asymetric
1868 ErrorDocument 301 "Some message
1870 Note the opening " quote, without a closing quote. It now
1871 has either the following syntaxes
1873 ErrorDocument XXX /local/uri
1874 ErrorDocument XXX http://valid/url
1875 ErrorDocument XXX "Some Message"
1877 The recognition heuristic is: if it has a space it
1878 is a message. If it has no spaces and starts with a /
1879 or is a valid URL then treat it that way. Otherwise it
1880 is assumed to be a message.
1882 This breaks backward compatibility but makes live a hell
1883 of a lot easier for GUI's and config file parsers.
1884 [Dirk-Willem van Gulik]
1886 *) Changed 'CacheNegotiatedDocs' from its present/not-present
1887 syntax into a 'on' or 'off' syntax. As it currently is the
1888 only non nesting token which uses NO_ARGS and thus is an
1889 absolute pain for any config interface automation. This
1890 breaks backward compatibility. [Dirk-Willem van Gulik]
1892 *) Add ability to add external modules to the build process. This is
1893 done with --with-module=/path/to/module. Modules can only be added
1894 as static modules at this point.
1897 Changes with Apache 2.0a1
1899 *) Fix FreeBSD 3.3 core dump.
1900 Basically, ap_initialize() needs to get called before
1901 create_process(), since create_process() passes op_on structure
1902 to semop() to get a lock, but op_on isn't initialized until
1903 ap_initialize() calls setup_lock(). Here is a slight
1904 rearrangement to main() which calls ap_initialize() earlier...
1905 [Jeff Trawick <trawick@us.ibm.com>]
1907 *) Enable Apache to use sendfile/TransmitFile API
1908 [Bill Stoddard, David Reid, Paul Reder]
1910 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
1914 *) Make file I/O and network I/O writev/sendv APIs consistent.
1915 Eliminate use of ap_iovec_t and use Posix struct iovec.
1916 Use seperate variable on ap_writev to set the number of iovecs
1917 passed in and number of bytes written.
1920 *) Adapt file iol to use APR functions. Replaced ap_open_file()
1921 with ap_create_file_iol(). ap_create_file_iol() requires that
1922 the file be opened prior to the call using ap_open().
1925 *) Port mod_include and mod_cgi to 2.0
1926 [Paul Reder, Bill Stoddard]
1928 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
1929 bytes_read/bytes_written is always valid (never -1). Plus
1930 some fixes to buff.c to correct problems introduced by the
1931 errno => ap_status_t changes a while back. Plus a fix to
1932 chunked encoding introduced right at the beginning of 2.0.
1935 *) Revamped UNIX build system to use autoconf and libtool.
1936 [Manoj Kasichainula, Sascha Schumann]
1938 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
1940 *) More rigorous checking of Host: headers to fix security problems
1941 with mass name-based virtual hosting (whether using mod_rewrite
1942 or mod_vhost_alias).
1943 [Ben Hyde, Tony Finch]
1945 *) Add back support for UseCanonicalName in <Directory> containers.
1946 [Manoj Kasichainula]
1948 *) Added APLOG_STARTUP log type. This allows us to write an error
1949 message without any of the date and time information. As a part
1950 of this change, I also removed all of the calls to fprintf(stderr
1951 and replaced them with calls to ap_log_error using APLOG_STARTUP
1952 writing to stderr is no longer portable, because we don't direct
1953 stderr to the error log on all platforms.
1956 *) Convert error logging functions to take errno as an argument.
1957 This makes our error logs more portable, because some Windows API's
1958 don't set errno. This change allows us to still output a valid
1959 message on all of our platforms.
1962 *) mod_mime_magic runs in 2.0-dev now.
1963 [Paul Reder <rederpj@raleigh.ibm.com>]
1965 *) sendfile has been added to APR.
1966 [John Zedlewski <zedlwski@Princeton.EDU>]
1968 *) buff.c has been converted to no longer use errno.
1969 [Manoj Kasichainula]
1971 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
1972 interface adaption to APR functions did it. [Martin Kraemer]
1974 *) Support DSOs properly on 32-bit HP-UX 11.0
1975 [Dilip Khandekar <dilip@cup.hp.com>]
1977 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
1978 [Ralf S. Engelschall]
1980 *) Cleaned APR build environment integration and bootstrap APR
1981 automatically for developers from src/Configure.
1982 [Ralf S. Engelschall]
1984 *) Fixed building of src/support/htpasswd.c
1985 [Ralf S. Engelschall]
1987 *) When generating the Location: header, mod_speling forgot
1988 to escape the spelling-fixed uri. (Forw-Port from 1.3)
1991 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
1993 *) Change all pools to APR contexts. This is the first step to
1994 incorporating APR into Apache. [Ryan Bloom]
1996 *) Move "handler not found" warning message to below the check
1997 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
1998 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
2000 *) Support line-continuation feature in config.option file and
2001 allow the loading of multiple option sections at once via
2002 ``--with-option=<section1>,<section2>,...''
2003 [Ralf S. Engelschall]
2005 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
2007 Changes with Apache MPM
2009 *) Use asynchronous AcceptEx() and a completion port to accept and
2010 dispatch connections to threads in Windows NT/2000.
2013 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
2016 *) Implement the APACI --with-option facility
2017 (per default used the config.option file).
2018 [Ralf S. Engelschall]
2020 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
2022 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
2023 Replace pre_connection module call with a register_hook call and
2024 implement pre_connection as a hook. The intent is that these hooks will
2025 be extended to allow Apache to be multi-protocol, and also to allow the
2026 calling order to be specified on a per-hook/per-module basis.
2029 *) Implement mpm_* methods as "modules". Each method gets its own
2030 subdir in src/modules (eg: src/modules/prefork). Selection
2031 of method uses Rule MPM_METHOD. [Jim Jagielski]
2033 *) Port the hybrid server from the apache-apr repository as
2034 mpm_mpmt_pthread. [Manoj Kasichainula]
2036 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
2037 amongst the unix MPMs.
2039 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
2040 signal handling for the new world order. [Dean Gaudet]
2042 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
2043 of alloc.c for now. [Dean Gaudet]
2045 *) Handle partial large writes correctly. [Ben Laurie]
2047 *) Eliminate conn_rec's pointer to server. All it knows is the base server
2048 based on IP/port. [Ben Laurie]
2050 *) Port a bunch of modules to the new module structure.
2051 ["Michael H. Voase" <mvoase@midcoast.com.au>]
2053 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
2055 *) Basic restructuring to introduce the MPM concept; includes various
2056 changes to the module API... better described by
2057 docs/initial_blurb.txt. [Dean Gaudet]
2059 Changes with Apache pthreads
2061 *) New buff option added: BO_TIMEOUT. It describes the timeout for
2062 buff operations (generally over a network).
2063 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
2065 *) Created http_accept abstraction. Added 4 new functions (not exported):
2066 init_accept(), begin_accepting_requests(), get_request(),
2067 stop_accepting_requests() [Bill Stoddard]
2069 *) Fix to ap_rprintf call that allows mod_info to work properly.
2070 [James Morris <jmorris@intercode.com.au>]
2072 *) user and ap_auth_type fields were moved from connection_rec to
2073 request_rec. [Ryan Bloom]
2075 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
2076 needed in a threaded server.
2078 *) Initial pthread implementation from from Dean's apache-nspr code.
2079 [Bill Stoddard, Ryan Bloom]
2082 Changes with Apache 1.3.9
2084 *) Remove bogus error message when a redirect doesn't set Location.
2085 Instead, use an empty string to avoid coredump if the error message
2086 was supposed to include a location. [Roy Fielding]
2088 *) Don't allow configure to include mod_auth_digest unless it is
2089 explicitly requested, even if the user asked for all modules.
2092 *) Translate module names to dll names for OS/2 so that they are no more
2093 than 8 characters long and have an extension of "dll" instead of "so".
2096 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
2097 Fix test-compile check to check for randbyte instead of trand32.
2098 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
2099 and tweak to make Amaya happier. [Ronald Tschalär]
2101 *) Ensure that the installed expat include files are world readable,
2102 just like the other header files. [Martin Kraemer]
2104 *) Fixed generated AddModule adjustments in APACI's `configure' script
2105 in order to allow (new) modules like mod_vhost_alias to be handled
2106 correctly (which was touched by the adjustments for mod_alias).
2107 [Ralf S. Engelschall]
2109 *) For binary builds, add -R flag to apachectl to work around the lack of
2110 an absolute path to the ./libexec directory where the libhttp.ep file
2111 is needed for SHARED_CORE architectures. [Randy Terbush]
2113 *) WIN32: Create the CGI script process as DETACHED. This may solve the
2114 problem observed by some Win95/98 users where they get CGI script
2115 output sent to the console. [Bill Stoddard]
2117 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
2118 routines are now called ap_base64* and are 'plain' (i.e., no
2119 pool access or anything clever). Inside util.c the routines acting
2120 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
2121 The oddly named ap_uuencode(), ap_uudecode() are kept around for
2122 now but deprecated. [dirkx]
2124 *) Clean up the base64 and SHA1 additions and make sure they are
2125 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
2126 files. [Roy Fielding]
2128 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
2129 checking. Allow compiling on VS 6.0. [Randy Terbush]
2131 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
2133 *) Use TestCompile to search for the truerand library (rather than blindly
2134 assuming its existence). If it is not found, complain (but do not
2135 exit - yet). [Martin Kraemer]
2137 *) We forgot to add the new exported function names to
2138 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
2140 *) Add description of -T command-line option to usage().
2141 [Ralf S. Engelschall]
2143 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
2144 searched only AFTER libap has been searched, because libap needs
2145 some symbols from libos. [Martin Kraemer]
2147 *) Fix conflict with original mod_digest related to the symbol of the
2148 module dispatch list (which has to be unique for DSO and follow the
2149 usual conventions for the installation procedure).
2150 [Ralf S. Engelschall]
2152 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
2153 for other platforms as well. [Martin Kraemer]
2155 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
2156 types by AP_LONG and replace reference to renamed variable 'ubuf'
2157 by 'buffer'. [Martin Kraemer]
2159 Changes with Apache 1.3.8 [not released]
2161 *) Flush the output buffer immediately after sending an error or redirect
2162 response, since the result may be needed by the client to abort a
2163 long data transfer or restart a series of pipelined requests.
2164 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
2166 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
2167 [Ian Turner <iant@sequent.com>] PR#4735
2169 *) Local struct mmap in http_core.c conflicted with system structure
2170 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
2172 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
2173 [Ronald Tschalär <ronald@innovation.ch>]
2175 *) Fix a memory leak where the module counts were getting messed
2176 up across restarts. [David Harris <dharris@drh.net>]
2178 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
2179 properly in mod_access.
2180 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
2182 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
2183 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
2185 *) PORT: Support for compaq/tandem/com.
2186 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
2188 *) Added SHA1 password encryption support to easy migration from
2189 Netscape servers. See support/SHA1 for more information.
2190 Caused the separation of ap_md5.c into md5, sha1 and a general
2191 ap_checkpass.c with just a validate_passwd routine. Added a
2192 couple of flags to support/htpasswd. Some reuse of the to64()
2193 function; hence renamed to ap_to64().
2194 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
2196 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
2197 with ASCII/EBCDIC conversions in "ident" query.
2198 [David McCreedy <McCreedy@us.ibm.com>]
2200 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
2201 Change "Power Macintosh" to Power* so if uname prints "Power Book"
2202 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
2204 *) Fix SIGSEGV on some systems because the Vary fix below included
2205 a call to table_do with a variable argument list that was not
2206 NULL terminated. Replaced with better implementation. [Roy Fielding]
2208 Changes with Apache 1.3.7 [not released]
2210 *) The "Vary" response header field is now sanitised right before
2211 the header is sent back to the client. Multiple "Vary" fields
2212 are combined, and duplicate tokens (e.g., "Vary: host, host" or
2213 "Vary: host, negotiate, host, accept-language") are reduced to
2214 single instances. This is a better solution than the force-no-vary
2215 one (which is still valid for clients that can't cope with Vary
2216 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
2218 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
2220 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
2221 least on Linux and FreeBSD for now.
2224 *) Win32: More apache -k restart work. Restarts are now honored
2225 immediately and connections in the listen queue are -not- lost.
2226 This is made possible by the use of the WSADuplicateSocket()
2227 call. The listeners are opened in the parent, duplicated, then
2228 the duplicates are passed to the child. The original listen sockets
2229 are not closed by the parent across a restart, thus the listen queue
2231 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2233 *) Fix handling of case when a client has sent "Expect: 100-continue"
2234 and we are going to respond with an error, but get stuck waiting to
2235 discard the body in the pointless hope of preserving the connection.
2236 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
2238 *) Fix 'configure' to work correctly with SysV-based versions of
2239 'tr' (consistent with Configure's use as well). [Jim Jagielski]
2241 *) apxs: Add "-S var=val" option which allows for override of CFG_*
2242 built-in values. Add "-e" option which works like -i but doesn't
2243 install the DSO; useful for editing httpd.conf with apxs. Fix
2244 editing code so that multiple invocations of apxs -a will not
2245 create duplicate LoadModule/AddModule entries; apxs can now be
2246 used to re- enable/disable a module. [Wilfredo Sanchez]
2248 *) Win32: Update the server to use Winsock 2. Specifically, link with
2249 ws2_32.lib rather than wsock32.lib. This gives us access to
2250 WSADuplcateSocket() in addition to some other enhanced comm APIs.
2251 Win 95 users may need to update their TCP/IP stack to pick up
2252 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
2253 [Bill Stoddard stoddard@raleigh.ibm.com]
2255 *) Win32: Redirect CGI script stderr (script debug info) into the
2256 error.log when CGI scripts fail. This makes Apache on Win32
2257 behave more like Unix.
2258 [Bill Stoddard stoddard@raleigh.ibm.com]
2260 *) Fixed `httpd' usage display: -D was missing.
2261 [Ralf S. Engelschall] PR#4614
2263 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
2264 [Ralf S. Engelschall] PR#4561, PR#4562
2266 *) OS/2: Fix problem with accept lock semaphores where server would die with
2267 "OS2SEM: Error 105 getting accept lock. Exiting!"
2268 [Brian Havard] PR#4505
2270 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
2271 [Randy Terbush <randy@covalent.net>]
2273 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
2274 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
2276 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
2277 command potentially _is_ GCC. [Ralf S. Engelschall]
2279 *) Fix apxs build issues on AIX
2280 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
2282 *) DocumentRoot Checking: Under previous versions, when Apache
2283 first started up, it used to do a stat of each DocumentRoot to
2284 see if it existed and was a directory. If not, then an error
2285 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
2286 does not exist, you will get error messages in error_log. If
2287 the '-t' command line option is used (to check the configuration)
2288 the check of DocumentRoot IS performed. An additional command
2289 line option, '-T', has been added if you want to avoid the
2290 DocumentRoot check even when checking the configuration.
2293 *) Win32: The query switch "apache -S" didn't exit after showing the
2294 vhost settings. That was inconsistent with the other query functions.
2295 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
2297 *) Win32: Changed behaviour of apache -k restart.
2298 Previously, the server would drain all connections in the stack's
2299 listen queue before honoring the restart. On a busy server, this
2300 could take hours. Now, a restart is honored almost immediately.
2301 All connections in Apache's queues are handled but connections in
2302 the stack's listen queue are discarded. Restart triggered by
2303 MaxRequestPerChild is unchanged.
2304 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2306 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
2307 the accept loop. Good for a 5% performance boost. Cleaned up
2308 parent/child process management code.
2309 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2311 *) Added ceiling on file size for memory mapped files.
2312 [John Giannandrea <jg@meer.net>] PR#4122
2314 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
2315 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
2316 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
2318 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
2319 use this at least for Expat. [Ralf S. Engelschall]
2321 *) Allow .module files to specify libraries with Lib:.
2324 *) Allow SetEnvIf[NoCase] to test environment variables as well
2325 as header fields and request attributes. [Ken Coar]
2327 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
2328 content-types are "text/html;parameters". PR#4524 [Ken Coar]
2330 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
2331 never accepted into any standard, and it opens up certain DoS
2332 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
2334 *) TestCompile updated. We can now run programs and output the
2335 results during the Configure process. [ Jim Jagielski]
2337 *) The source is now quad (long long) aware as needed. Specifically,
2338 the Configure process determines the correct size of off_t and
2339 *void. When the OS/platform/compiler supports quads, ap_snprintf()
2340 provides for the 'q' format qualifier (if quads are not available,
2341 'q' is silently "demoted" to long). [Jim Jagielski]
2343 *) When the username or password fed to htpasswd is too long, include the
2344 size limit in the error message. Also report illegal characters
2345 (currently only ':') in the username. Add the size restrictions
2346 to the man page. [Ken Coar]
2348 *) Fixed the configure --without-support option so it doesn't result in
2349 an infinite loop. [Marc Slemko]
2351 *) Piped error logs could cause a segfault if an error occured
2352 during configuration after a restart.
2353 [Aidan Cully <aidan@panix.com>] PR#4456
2355 *) If a "Location" field was stored in r->err_headers_out rather
2356 than r->headers_out, redirect processing wouldn't find it and
2357 the server would core dump on ap_escape_html(NULL). Check both
2358 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
2359 if Location isn't set. [Doug MacEachern, Ken Coar]
2361 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
2362 of the Expat 1.0.2 distribution. [Greg Stein]
2364 *) Replace regexec() calls with calls to a new API stub function
2365 ap_regexec(). This solves problems with DSO modules which use the regex
2366 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
2368 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
2369 environment variables can be set according to the protocol version
2370 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]

2387 *) Support for server-parsed and multiview-determined ReadmeName and
2388 HeaderName files in mod_autoindex. Removed the restriction on
2389 "/"s in ReadmeName and HeaderName directives since the *sub_req*
2390 routines will deal with the access issues. (It's now possible to

2427 being newer than Configuration so that it is less likely to fail
2428 when using APACI and shadow sources. [Wilfredo Sanchez]
2430 *) PORT: Add initial support for Mac OS (versions 10.0 and
2431 greater). Use Mac OS X Server layout for now. Clean up dyld code
2432 in unix/os.c, and don't install the dyld error handlers, which
2433 are no longer needed in Mac OS. [Wilfredo Sanchez]
2435 *) Rename Rhapsody layout to "Mac OS X Server". Change install
2436 locations to appropriate ones for user-built (as opposed to
2437 system) installs. [Wilfredo Sanchez]
2439 *) Modify mod_autoindex's handling of AddDescription so that the
2440 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
2442 *) Add functionality to the install-bindist.sh script created by
2443 binbuild.sh to use tar when copying distribution files to the
2444 serverroot. This allows upgrading an existing installation
2445 without nesting the new distribution in the old.
2447 install-bindist.sh now detects the local perl5 path to install
2448 apxs and dbmmanage with proper path to perl interpreter.
2450 Add an install-binsupport target which copies the source files
2451 for apxs and dbmmanage to bindist to allow these scripts to
2452 be properly installed relative to the destination serverroot.

2569 htpasswd utility was limiting passwords to only 8 characters.
2572 *) EBCDIC platforms: David submitted patches for two bugs in the
2573 MD5 digest port for EBCDIC machines:
2574 a) the htdigest utility overwrote the old contents of the digest file
2575 b) the Content-MD5 header value (ContentDigest directive) was wrong
2576 when the returned file was not converted from EBCDIC, but was a
2577 binary (e.g., image file) in the first place.
2578 [David McCreedy <mccreedy@us.ibm.com>]
2580 *) support/htpasswd now permits the password to be specified on the

2619 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
2620 a roughly 5 fold speed up. [Brian Havard]
2622 *) proxy ftp: instead of using the hardwired string "text/plain" as
2623 a fallback type for files served by the ftp proxy, use the
2624 ap_default_type() function to determine the configured type.
2625 This allows for special configurations like
2626 <Directory proxy:ftp://some.host>
2627 DefaultType gargle/blurb
2629 Additionally, add the Content-Encoding: header to FTP proxy replies
2630 when the encoding is defined (by the AddEncoding directive).
2631 Because it was missing, it was almost impossible to browse compressed
2632 files using the FTP proxy (works now perfectly in Communicator).
2633 The ftp proxy now also returns the Date: and Server: header lines (if not
2634 much else... This code is "somewhat" broken) like normal requests do.
2637 *) Be more smart in APACI's configure script when determining the UID/GID
2638 for User/Group directives and use the determined UID/GID to initialize
2639 the permissions on the proxycachedir.
2640 [Dirk-Willem van Gulik, Ralf S. Engelschall]
2642 *) Changed the forking-prior-to-cleanup in the proxy module to first

2644 the number of fork()s from one/request to just the odd one an hour.
2645 [Dirk-Willem van Gulik]

2674 *) M_INVALID needed a value within the scope of METHODS so that unknown
2675 methods can be access controlled. [Roy Fielding] PR#3821
2677 *) Added PassAllEnv; makes server's entire environment available
2678 to CGIs and SSIs executed within directive's scope. [Ken Coar]
2680 *) ap_uuencode() always added two trailing '='s and encoding of
2681 8 bit characters on a machine with signed char may produced
2682 incorrect results. Additionally ap_uuencode() should now
2683 work correctly on EBCDIC platforms.
2684 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
2686 *) WIN32: Binary installer now runs the configuration DLL before
2687 the reboot prompt (which is only given if MSVCRT.DLL system
2688 DLL is new or updated). This should avoid the configuration
2689 directory being empty after installation. [Paul Sutton]
2690 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988

2713 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
2714 for 8-bit safeness. [Dean Gaudet]
2716 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
2717 because SPARCs have a small machine-specific maximum size for the Global
2718 Offset Table which is often exceeded when compiling one of the larger
2719 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
2721 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the

2748 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
2751 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
2752 to make platform installations easier. [Wilfredo Sanchez]
2754 *) In configure, do not append the target name to the directory path if
2755 the path already contains "apache". [Ralf S. Engelschall]
2757 *) SIGPIPE is now ignored by the server core. The request write routines
2758 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
2759 correctly check for output errors and mark the connection as aborted.
2760 Replaced many direct (unchecked) calls to ap_b* routines with the
2761 analogous ap_r* calls. [Roy Fielding]
2763 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
2764 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
2765 Furthermore map lookups for non-existent keys are now cached as well.
2766 Additionally "txt" maps are now parsed with simple string functions
2767 instead of using ap_pregcomp(). As a side effect a bug that prevented
2768 the usage of keys containing the "," character was fixed.
2769 The changes drastically improve the performance when large rewrite maps
2771 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160

2779 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
2780 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
2782 *) Add %V to mod_log_config, this logs the hostname according to the
2783 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
2784 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
2786 *) Add support for \n and \t to mod_log_config, can be used to produce
2787 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
2789 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
2791 *) Added informative error messages for failed munmap() and fseek() calls

2795 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
2797 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
2798 is removed. This allows <Directory proxy:*> directives to work and
2799 prevents invalid requests from killing the process.
2800 [Brian Havard <brianh@kheldar.apana.org.au>]
2802 *) Reorganised FAQ document.

2806 David N. Welton: you can now have it generate an HTML TABLE, presumably
2807 for integration into other HTML sources. David updated the ab man page
2808 as well and added some missing descriptions. Thanks!
2809 [David N. Welton <davidw@prosa.it>]
2811 *) Win32: The filename validity checker now allows filenames containing
2812 characters in the range 0x80 to 0xff (for example accented characters).
2813 [Paul Sutton] PR#3890
2815 *) Added conditional logging based upon environment variables to
2816 mod_log_config. mod_log_referer and mod_log_agent
2817 are now deprecated. [Ken Coar]
2819 *) Allow apache acting as a proxy server to relay the real
2820 reason of a failure to a client rather than the "internal
2821 server error" it does currently. The general exposure mechanism
2822 can be triggered by any module by setting the "verbose-error-to"
2823 note to "*"; this allows more than just proxy errors to be exposed.

2826 *) Moved man pages for ab and apachectrl to section 8.
2827 [Wilfredo Sanchez, Roy Fielding]
2829 *) Added -S option to install.sh so that options can be passed to
2830 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
2832 *) Tweak modules Makefile generated by Configure so that it handles
2833 the test case of no modules being selected. [chaz@reliant.com]
2835 *) Added a <LimitExcept method ...> sectioning directive that allows
2836 the user to assign authentication control to any HTTP method that
2837 is *not* given in the argument list; i.e., the logical negation
2838 of the <Limit> directive. This is particularly useful for controlling
2839 access on methods unknown to the Apache core, but perhaps known by
2840 some module or CGI script. [Roy Fielding, Tony Finch]
2842 *) Prevent apachectl from complaining if the PIDFILE exists but
2843 does not contain a process id, as might occur if the server is
2844 being rapidly restarted. [Wilfredo Sanchez]
2846 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
2848 *) Entity tag comparisons for If-Match and If-None-Match were not being

2850 strong comparison wasn't properly enforced in all cases.

2856 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
2857 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
2859 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
2860 to util.c for parsing an HTTP header field value to extract the next
2861 list item, taking into account the possible presence of nested comments,
2862 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
2863 insignificant whitespace and lowercases non-quoted tokens.
2864 [Roy Fielding] PR#2065
2866 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
2867 code different from 500. This allows the proxy to, e.g., return
2868 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
2870 *) Fix ordering of language variants for the case where the traditional
2871 negotiation algorithm is being used with multiple language variants
2872 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
2874 *) Do not round the TCN quality calculation to 5 decimal places,
2875 unlike RFC 2296, because the calculation might need 12 decimal places
2876 to get the right result. [Roy Fielding]
2878 *) Remove unused code to disable transparent negotiation when
2879 negotiating on encoding only, as we now handle encoding too
2880 (though this is nonstandard for TCN), remove charset=ISO-8859-1
2881 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
2882 some debugging statements within mod_negotiation. [Koen Holtman]
2884 *) Fixed a rare memory corruption possibility in mod_dir if the index
2885 file is negotiable and no acceptable variant can be found.
2886 [Dean Gaudet, Roy Fielding, Martin Kraemer]
2888 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
2889 searching the Win32 registry for script interpreters.
2892 *) Win32: The compiled-in default filename for the error log is now
2893 error.log, which matches the default in the distributed httpd.conf.
2896 *) Win32: Any error messages from -i or -u command line options are now
2897 displayed on the console output rather than sent to the error log.
2898 Also the "Running Apache..." message is not output unless Apache is
2899 going to serve requests. [Paul Sutton]
2901 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
2902 and use a private significator ('$apr1$') to mark passwords as
2903 being smashed with our own algorithm. Also abstract the password
2904 checking into a new ap_validate_password() routine. [Ken Coar]
2906 *) Win32: The filename validity checker now allows "COM" but refuses
2907 access to "COM1" through "COM4". This allows filenames such
2908 as "com.name" to be served. [Paul Sutton] PR#3769.
2910 *) BS2000: Adapt to the new ufork() system call interface which will
2911 make subtasking easier on the OSD/POSIX mainframe environment.
2914 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
2915 ap_compat.h. [David White <david@persimmon.com>] PR#3725
2917 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
2918 use `.db' instead of `.pag' not only for FreeBSD, but also when
2919 the NDBM library looks like Berkeley-DB based.
2920 [Ralf S. Engelschall] PR#3773
2922 *) Add ability to handle DES or MD5 authentication passwords.
2923 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
2925 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
2927 *) SECURITY: Avoid some buffer overflow problems when escaping
2928 quoted strings. (This overflow was on the heap and we believe
2929 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
2931 *) Let src/Configure be aware of CFLAGS options starting with plus
2932 signs as it's the case for the HP/UX compiler.
2933 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
2935 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
2936 and check to see if the tar we wind up with supports '-h'.
2937 [Jim Jagielski] PR#3671
2939 *) A consistent and conservative style for all shell scripts has been
2940 implemented. Basically, all shell string tests use the traditional
2941 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
2942 to protect against bare null variable strings (ie: wrapping both
2943 sides with double quotes and prepending 'x'). 'x' was chosen
2944 because it's more universal and hopefully easier for old shell
2945 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
2948 *) The status module now prints out both the main server generation as
2949 well as the generation of each process. Also, the vhost info is
2950 printed with '?notable'. [Jim Jagielski]
2952 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
2953 and this makes its functions available to things in src/support.
2956 Changes with Apache 1.3.4
2958 *) Renamed macros status_drops_connection to ap_status_drops_connection
2959 and vestigial scan_script_header to ap_scan_script_header_err,
2960 mostly for aesthetic reasons. [Roy Fielding]
2962 *) The query switch "httpd -S" didn't exit after showing the
2963 vhost settings. That was inconsistent with the other query functions.
2966 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
2967 filename to the end of the STANDARD_MODULE_STUFF. Its
2968 presence at the beginning prevented reporting of the filename
2969 for modules compiled before 1 January 1999. [Ken Coar]
2971 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
2972 to detect and prevent access to special DOS device file names.
2973 [Paul Sutton, Ken Parzygnat]
2975 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
2976 and Makefile_win32_debug.txt (debug build) that work on Win95.
2977 Run each of the following from the src directory:
2978 nmake /f Makefile_win32.txt # compiles normal build
2979 nmake /f Makefile_win32.txt install # compiles and installs
2980 nmake /f Makefile_win32.txt clean # removes compiled junk
2981 nmake /f Makefile_win32_debug.txt # compiles debug build
2982 nmake /f Makefile_win32_debug.txt install
2983 nmake /f Makefile_win32_debug.txt clean
2986 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
2987 to build binary distributions. [Lars Eilebrecht]
2989 *) IndexOptions SuppressColumnSorting only turned off making
2990 the column headers anchors; you could still change the display
2991 order by manually adding a '?N=A' or similar query string to the
2992 URL. Now SuppressColumnSorting locks in the sort order so
2993 it can't be overridden this way. [Ken Coar]
2995 *) Added IndexOrderDefault directive to supply a default sort order
2996 for FancyIndexed directory listings. [Ken Coar] PR#1699
2998 *) Change the ap_assert macro to a variant that works on all platforms.
2999 [Richard Prinz <richard.prinz@cso.net>] PR#2575
3001 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
3002 search for an underscore on dlsym() (as it's already the case
3003 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
3005 *) Small fix for mod_env.html: The module was documented as to be _not_
3006 compiled into Apache per default, although it _IS_ compiled into
3007 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
3009 *) Instead of fixing a bug in the generation procedure for config.status (a
3010 backslash was missing) we remove the bug together with it's complete
3011 context because the special cases of the past can now no longer occur
3012 because of the recent magic for the --with-layout default.
3013 [Ralf S. Engelschall] PR#3590
3015 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
3016 making sure the src/support/ tools are _forced_ to be build last (they
3017 depend on other libraries).
3018 [Markus Theissinger <markus.theissinger@gmx.de>]
3020 *) Fix installation procedure: Now that os-inline.c is actually used (a
3021 recently fixed bug prevented this) we need to also install os-include.c
3022 in addition to os.h into the PREFIX/include/ location or building of
3023 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
3025 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
3026 allow us to distinguish between a garbled DSO (or even a file which isn't
3027 an Apache module DSO at all) and a DSO which doesn't match the current
3028 Apache API. [Ralf S. Engelschall] PR#3152
3030 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
3031 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
3032 match case insensitive (this especially avoids nasty patterns like
3033 `[tT][eE][sS][tT]'). Second two additional internal map functions
3034 `escape' and `unescape' were added which can be used to escape/unescape
3035 to/from hex-encodings in URLs parts (this is especially useful in
3036 combination with map lookups).
3037 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
3039 *) Renamed the macro escape_uri() to ap_escape_uri() which was
3040 forgotten (because it was a macro) in the symbol renaming process.
3041 [Ralf S. Engelschall]
3043 *) Fix some inconsistencies related to the scopes of directives. The only
3044 user visible change is that the directives `UseCanonicalName' and
3045 `ContentDigest' now use the (more correct) `Options' scope instead of
3046 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
3048 *) Using DSO, the Server token was being mangled. Specifically, the
3049 module's token was being added first before the Apache token. This
3050 has been fixed. [Jim Jagielski]
3052 *) Major overhaul of mod_negotiation.c, part 2.
3053 - properly handle "identity" within Accept-Encoding.
3054 - allow encoded variants in RVSA negotiation and let them appear in
3055 the Alternates field using the non-standard "encoding" tag-list.
3056 - fixed both negotiation algorithms so that an explicitly accepted
3057 encoding is preferred over no encoding if "identity" is not
3058 included within Accept-Encoding.
3059 - added ap_array_pstrcat() to alloc.c for efficient concatenation
3060 of large substring sequences.
3061 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
3064 *) Major overhaul of mod_negotiation.c, part 1.
3065 - cleanups to mod_negotiation comments and code structure
3066 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
3067 support for everything in the upcoming HTTP/1.1
3068 revision (draft-ietf-http-v11-spec-rev-06.txt).
3069 - language tag matching also handles tags with more than 2
3071 - empty Accept, Accept-Language, Accept-Charset headers are
3072 processed correctly; previously an empty header would make all
3073 values acceptable instead of unacceptable.
3074 - allowed for q values in Accept-Encoding
3075 - added support for transparent content negotiation (rfc2295 and
3076 rfc2296) (though we do not implement all features in these drafts,
3077 e.g. no feature negotiation). Removed old experimental version.
3078 - implemented 'structured entity tags' for better cache correctness
3079 (structured entity tags ensure that caches which can deal with Vary
3080 will (eventually) be updated if the set of variants on the server
3082 - this involved adding a vlist_validator element to request_rec
3083 - this involved adding the ap_make_etag() function to the global API
3084 - modified guessing of charsets used by Apache negotiation algorithm
3085 to guess 'no charset' if the variant is not a text/* type
3086 - added code to sort multiviews variants into a canonical order so that
3087 negotiation results are consistent across backup/restores and mirrors
3088 - removed possibility of a type map file resolving to another type map
3089 file as its best variant
3090 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
3092 *) RFC2396 allows the syntax http://host:/path (with no port number)
3093 but the proxy disallowed it (ap_proxy_canon_netloc()).
3094 [David Kristol <dmk@bell-labs.com>] PR#3530
3096 *) When modules update/modify the file name in the configfile_t structure,
3097 syntax errors will report the updated name, not the original one.

3100 *) Correct some filename case assumptions from WIN32 to
3101 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]
3103 *) For %v log ServerName regardless of the UseCanonicalName
3104 setting (similarly for %p). [Dean Gaudet]
3106 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
3107 rather late (too late for some invocations of TestCompile).
3108 This improves the make environment available to TestCompile and
3109 the *.module scripts. [Martin Kraemer]
3111 *) The hashbang emulation code in ap_execve.c would interpret
3112 #!/hashbang/scripts correctly, but failed to fall back to a
3113 standard shell for scripts which did NOT start with #!
3114 Now SHELL_PATH is started in these cases. [Martin Kraemer]
3116 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
3119 *) Update APXS manual page: some -q option arguments were missing
3120 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
3122 *) Cleanup the command line options: `-?' was documented to show
3123 the usage list but does it with an error because `?' is not a valid
3124 command. OTOH a lot of users expect `-h' to print such a usage list and
3125 instead are annoyed for ages by our huge unreadable list of directives.
3126 So we now changed the command line options this way:
3128 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
3129 very similar to the popular linker option.
3131 Intent: while -l gives the small list of modules, -L now gives the
3132 large list of directives implemented by these modules. This is also
3133 consistent with -v (short version info) and -V (large version info).
3135 Intent: it's now the expected option ;-)
3136 The manual page was adjusted accordingly.
3137 [Ralf S. Engelschall] PR#2714
3139 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
3140 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
3142 *) Removed recently introduced bugs and disfigurements in APACI:
3143 o fixed argument line processing: using $args was broken: It was not
3144 initialized and using args="$args $apc_option" and even args="$args
3145 \"$apc_option\"" fails in the second processing round for any arguments
3146 containing whitespaces. The only correct way is to use the construct
3147 "$@" (but not possible here) or iterate _both_ times over the implicit
3148 argument line (no argument to for-loop) which is what we now use.
3149 o make --with-layout=Apache the default without creating
3150 redundancy (copying the --with-layout block in the argument parsing
3151 loop). We achieve this by using the "$@" construct together with the
3152 `set' command to prepend --with-layout=Apache to the command line in
3153 case --with-layout is not used.
3154 o fixed auto-suffix handling now that config.layout exists.
3155 Paths which are auto-suffixed are marked with a trailing plus sign in
3156 config.layout and every path now can be marked this way (not only the
3157 four paths for which we do it currently). Additionally the suffix is
3158 no longer a static one. Instead it's now `/<target>' where <target> is
3159 the argument of the --target option or per default `httpd'.
3160 o allow also tabs (and only spaces) where we match whitespaces
3161 o various fixes and cleanups related to used shell coding style
3162 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
3163 o trimmed output of --help to fit into 80 columns
3164 [Ralf S. Engelschall]
3166 *) Added two new core API functions, ap_single_module_configure() and
3167 ap_single_module_init(), which are now used by mod_so to configure a module
3168 after loading. [Ralf S. Engelschall]
3170 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
3171 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
3172 of ap_config.h to allow serialized accept for multiport listens.
3173 [Roy Fielding, Curt Sampson] PR#3120
3175 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
3176 of ap_config.h that would skip several defines if DEFAULT_GROUP
3177 was overridden. [Roy Fielding]
3179 *) PORT: The I86 version of DGUX has support for strncasecmp and
3180 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
3182 *) Fix ordering of definitions in ap_config.h so that ap_inline is
3183 defined before it might be used. [Victor Khimenko]
3185 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
3186 [Tom Serkowski <tks@bsdi.com>] PR#3453
3188 *) Make generation of src/Configuration.apaci more robust: It failed to
3189 differenciate between modules when one module name was a postfix of
3190 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
3191 just XXX (think about totally non-standard names like "apache_ssl", too).
3192 [Ralf S. Engelschall] PR#3380
3194 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
3195 since 1.3b7) and make whitespace handling more robust (it failed horrible
3196 when whitespaces were present in the arguments of -D options).
3197 [Ralf S. Engelschall] PR#3240
3199 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
3200 creates an external package shadow tree in DIR before the local build
3201 shadow tree is generated under DIR. This way one can have the extracted
3202 Apache distribution tree read-only on NFS or CDROM and still build Apache
3203 from these sources. An automatically triggered VPATH-like mechanism is
3204 provided through the TOP variable, too.
3205 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez@apple.com>]
3207 *) Fix negotiation so that a Vary response header is correctly
3208 generated when, for a particular dimension, variants only vary
3209 in having or not having a value for that dimension. [Paul Sutton]
3211 *) Fix negotiation so that we prefer an encoded variant over an
3212 unencoded variant if the user-agent explicitly says it can
3213 accept that encoding. Previously we always preferred the unencoded
3215 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
3217 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
3218 and the usage page was inconsistent with the functionality and manpage.
3219 [Ralf S. Engelschall]
3221 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
3222 They can occur multiple times and their arguments (`xxx') are passed AS
3223 IS to the compiler/linker command. [Ralf S. Engelschall]
3225 *) Fixed possible (but harmless in practice) bug in the DBM lookup
3226 procedure of mod_rewrite: very long keys were truncated.
3227 [Ralf S. Engelschall]
3229 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
3230 identifier, currently "Apache" and "GNU" are pre-defined in the file
3231 config.layout. Custom layouts are possible by using FILE:ID as the
3232 argument where the layout ID is taken from FILE.
3234 The config.layout file consists of <Layout ID>..</Layout> sections
3235 where inside those sections "path_variable: path_value" pairs can be
3236 specified. These lines are converted to path_variable='path_value'.
3238 *) Add a DefaultLanguage directive so that files missing a language
3239 extension (e.g., .fr, .de) can be labelled as being some other
3240 default language. DefaultLanguage can appear in <Directory> and
3241 <Files> containers as well as .htaccess files. [Paul Sutton]
3244 *) Fix TARGET configuration when configuring and installing using
3245 APACI configure. TARGET now defines the basename of the configuration
3246 file, startup script, manual page, etc. log_error_core() now reports
3247 the server binary name given by argv[0]. TARGET can now also be defined
3248 with --target=TARGET parameter passed to APACI configure.
3249 [Ralf Engelschall, Randy Terbush]
3251 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
3252 rather than OPT_INCLUDES [Rainer Schoepf <schoepf@uni-mainz.de>]

3346 release A17, the child fork() must be replaced by a _rfork().
3347 (BS2000 only) [Martin Kraemer]
3349 *) Add the actual server_rec structure of the specific Vhost to the
3350 scoreboard file and avoid a string copy (as well as allow some
3351 further future enhancements). [Harrie Hazewinkel
3352 <harrie.hazewinkel@jrc.it>]
3354 *) Add APACI --permute-module=foo:bar option which can be used to
3355 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
3356 in the Configuration[.apaci] file. Two special and important variants are
3357 supported for the option argument: first BEGIN:foo which permutes module
3358 mod_foo with the begin of the module list, i.e. it `moves' the module to
3359 the begin of the list (gives it lowest priority). And second foo:END
3360 which permutes mod_foo with the end of the module list, i.e. it `moves'
3361 the module to the end of the list (gives it highest priority).
3362 [Ralf S. Engelschall]
3364 *) Fix problem with 'apache -k shutdown' and startup event
3365 synchronisation (Win32). [Ken Parzygnat <kparz@raleigh.ibm.com>]
3368 *) The config parser wasn't correctly noticing a missing '>'
3369 on container start lines (e.g., it wouldn't spot
3370 "<Directory /" as a syntax error). [Ryan Bloom <rbbloom@us.ibm.com>]
3373 *) Add a 'RemoveHandler' directive which will selectively remove
3374 all handler associations for the specified file extensions.
3375 [Ryan Bloom <rbbloom@us.ibm.com>] PR#1799.
3377 *) Properly handle & allow "nul" and ".*/null" in AccessConfig and
3378 ResourceConfig directives on Win32. Also add a note to the effect
3379 of 'useless User directive ignored on Win32' to the errorlog if
3380 a User directive is encountered on Win32.

3383 *) Fix multiple whitespace handling in imagemaps for mod_imap which was
3384 broken since Apache 1.3.1 where we took out compressing of multiple
3385 spaces in ap_cfg_getline().
3386 [Ivan Richwalski <ivan@seppuku.net>] PR#3249
3388 *) Fix Berkeley-DB/2.x support in mod_auth_db: The data structures were not
3389 initialized correctly and the db_open() call used an invalid mode
3390 parameter. [Ron Klatchko <ron@ckm.ucsf.edu>] PR#3171
3392 *) PORT: DSO support for UnixWare 7
3393 [Ralf S. Engelschall, Ron Record <rr@sco.com>]
3395 *) Merge the contents of the {srm,access}.conf-dist* files into the
3396 httpd.conf-dist* files. The srm and access files now contain
3397 only comments, and httpd.conf has all the combined contents in
3398 a rational order. [Ken Coar]
3400 *) PORT: DSO/ELF support for FreeBSD 3.0.
3401 [Ralf S. Engelschall, Dirk Froemberg <ibex@physik.TU-Berlin.DE>]
3403 *) Add a "default-handler" handler that calls the default_hander()
3404 function which is normally called for static content. This allows
3405 you to override a specific handler. [Marc Slemko]
3407 *) Further simplify checking for absolute paths by replacing an
3408 hard-coded syntax check with a call to a routine we already created to
3409 do this. [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2976, 3074
3411 *) Log an error if we encounter a malformed "require" directive
3412 in mod_auth if we know that we know that no other module can
3413 deal with it. [Marc Slemko]
3415 *) Remove ap_private_extern method of hiding conflicting symbols
3416 on the NEXT platform because it is not correct for all versions,
3417 and the versions for which it is correct are unknown.
3418 [Wilfredo Sanchez <wsanchez@apple.com>]
3420 *) Fix inheritance of IndexOptions NameWidth and remove unintended
3421 restriction on +NameWidth, +IconHeight, and +IconWidth. [Ken Coar]
3423 *) Fix per-directory config merging for cases in which a 500 error
3424 is encountered in an .htaccess file somewhere down the tree.
3427 *) Minor performance improvement to ap_escape_html(). [Roy Fielding]
3429 *) Fixed a segmentation violation in mod_proxy when a response is
3430 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
3432 Changes with Apache 1.3.3
3434 *) Added a complete implementation of the Expect header field as
3435 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
3436 response when we already know the final status, which is mighty
3437 useful for PUT responses that result in 302 or 401. [Roy Fielding]
3439 *) Remove extra trailing whitespace from the getline results as part
3440 of the protocol processing, which is extra nice because it works
3441 between continuation lines, is almost no cost in the normal case
3442 of no extra whitespace, and saves memory. [Roy Fielding]
3444 *) Added new HTTP status codes and default response bodies from the
3445 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
3446 HTTP Extension Framework (510) specifications. Did not add the
3447 WebDAV 424 and 425 codes because they are bogus. We don't use any
3448 of these codes yet, but they are now available to 3rd-party modules.
3451 *) Fix a possible race condition between timed-out requests and the
3452 ap_bhalfduplex select that might result in an infinite loop on
3453 platforms that do not validate the descriptor. [Roy Fielding]
3455 *) WIN32: Add "-k shutdown" and "-k restart" options to signal a
3456 running Apache server [Paul Sutton]
3458 *) Fix mod_autoindex bug where directories got a size of "0k" instead
3459 of "-". [Martin Plechsmid <plechsmi@karlin.mff.cuni.cz>, Marc Slemko]
3462 *) PORT: DRS 6000 machine. [Paul Debleecker <pdebleecker@jetair.be>]
3464 *) Add the server signature text (from the core ServerSignature directive)
3465 to the list of envariables available to scripts, SSI, and the like.
3468 *) PORT: Fix sys/resource.h handling for SCO 3.x platform.
3469 [M. Laak <maert@proinv.ee>] PR#3108
3471 *) Fallback from sysconf-based to plain HZ-based `ticks per second'
3472 calculation in mod_status for all systems which don't have POSIX
3473 sysconf() (like UTS 2.1) and not only for the NEXT platform.
3474 [Dave Dykstra <dwd@bell-labs.com>] PR#3055
3476 *) Fix `require ...' directive parsing in mod_auth, mod_auth_dbm and
3477 mod_auth_db by using ap_getword_white() (which uses ap_isspace())
3478 instead of ap_getword(..., ' ') (which parses only according to spaces
3479 but not tabs). [James Morris <jmorris@intercode.com.au>,
3480 Ralf S. Engelschall] PR#3105
3482 *) Fix the SERVER_NAME variable under sub-request situations (where
3483 `UseCanonicalName off' is used) like CGI's called from SSI pages or
3484 RewriteCond variables by adopting r->hostname to sub-requests.

3499 it is now taken care of properly by the header file tests.

3506 working directory to fill in some blanks. [Ken Parzygnat

3514 so that ErrorDocument 300 processors can reformat the list
3515 if desired. [Ken Coar] PR#2859

3518 enable merging of multiple IndexOptions directives. [Ken Coar]
3520 *) PORT: Allow GuessOS to recognize Unixware 7.0.1 [Steve Cameron
3521 <steve.cameron@compaq.com>]
3523 *) Reconstructed the loop through multiple htaccess file names so
3524 that missing files are not confused with unreadable files.
3527 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
3528 errno on an error, which leads to one error being mistaken for
3529 another when reading non-existent .htaccess files.
3532 *) OS/2: The new header tests get things right, need to update
3533 ap_config.h. [Brian Havard]
3535 *) The Perl %ENV hash will now be setup by default when using the
3536 mod_include `perl' command [Doug MacEachern]

3547 *) Avoid possible line overflow in Configure: Use an awkfile to
3548 handle the creation of modules.c [Jim Jagielski]
3550 Changes with Apache 1.3.2
3552 *) Fix bug in ap_remove_module(), which caused problems for dso's
3553 who were the top_module. [Doug MacEachern]
3555 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
3556 mod_auth_db to both be friendly to users who wants to use this version
3557 and to avoid problems under platforms where only version 2.x is present.
3558 [Dan Jacobowitz <drow@false.org>, Ralf S. Engelschall]
3560 *) When using ap_log_rerror(), make the error message available to the
3561 *ERROR_NOTES envariables by default. [Ken Coar]
3563 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
3564 You now must define a BS2000Account name for the server User.
3565 This has fewer security implications than the old approach.
3568 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
3569 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
3570 platform to make the braindead HPUX linker happy. Notice, for the module
3571 DSOs we don't have to use this, because these are loaded manually (and
3572 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
3574 *) Remove 64 thread limit on Win32.
3575 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3577 *) Remove redundant substitutions in top-level Makefile.tmpl.
3578 [Ralf S. Engelschall]
3580 *) Fix APACI's `Group' configuration adjustment - especially for Linux
3581 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
3583 *) Make PrintPath work generically instead of having one version
3584 strictly for OS/2. [Jim Jagielski, Brian Havard]
3586 *) Fix the recently introduced C header file checking: We now use the C
3587 pre-processor pass only (and no longer the complete compiler pass) to
3588 determine whether a C header file exists or not. Because only this way
3589 we're safe against inter-header dependencies (which caused horrible
3590 portability problems). The only drawback is that we now have a CPP
3591 configuration variable which has to be determined first (we do a similar
3592 approach as GNU Autoconf does here). When all fails the user still has
3593 the possibility to override it manually via APACI or src/Configuration.
3594 As a fallback for the header check itself we can directly check the
3595 existance of the file under /usr/include, too.
3596 [Ralf S. Engelschall] PR#2777
3598 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined

3601 dynamic libraries on the NEXT and RHAPSODY platforms.

3620 used -lprot. It's actually a bug in SCO5, of course.

3623 *) Fix documentation of ProxyPass/ProxyPassReverse according to the
3624 trailing slash problem. [Jon Drukman <jsd@gamespot.com>] PR#2933
3626 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
3627 platform, because it's only supported under version 4.0 and higher. But
3628 because our GuessOS is still unaware of Digital UNIX versions and the
3629 -msym is just to optimize the DSO statup time a little bit it's safe and
3630 best when we leave it out now. [Ralf S. Engelschall] PR#2969
3632 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
3633 functions: First all three functions no longer fail on strings containing
3634 "%" chars and second ap_log_printf() no longer does a double-formatting
3635 (instead it directly passes through the message to be formatted to the
3636 real internal formatting function). [Ralf S. Engelschall] PR#2941
3638 *) Allow "Include" directives anywhere in the server config
3639 files (but not .htaccess files). [Ken Coar] PR#2727
3641 *) The proxy was refusing to serve CONNECT requests except to
3642 port 443 (https://) and 563 (snews://). The new AllowCONNECT
3643 directive allows the configuration of the ports to which a
3644 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
3646 *) mod_expires will now act on content that is not sent from a file
3647 on disk. Previously it would never add an Expires: header to
3648 any response that did not come from a file on disk; the only
3649 case where it still doesn't (and can't) add one for that type of
3650 content is if you are using a modification date based setting.
3651 [Marc Slemko, Paul Phillips <paulp@go2net.com>]
3653 *) Problems encountered during .htaccess parsing or CGI execution
3654 that lead to a "500 Server Error" condition now provide explanatory
3655 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
3658 *) Add NameWidth keyword to IndexOptions directive so that the
3659 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
3662 *) Recognize lowercase _and_ uppercase `uname' results under
3663 SCO OpenServer. [David Coelho <drc@ppt.com>]
3665 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
3666 a common problem of (mis-administrated?) IIS servers, make the apache
3667 proxy immune to these errors (and ignore the duplicates, but log
3668 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
3670 *) The <IfModule and <IfDefine block starting directives now only
3671 allow exactly one argument. Previously, the optional negation
3672 character '!' could be separated by whitespace without a syntax
3673 error being reported, albeit defeating the IfModule functionality
3674 (enclosed directives would ALWAYS be executed). By using the
3675 stricter syntax, these hard-to-track errors can be avoided.
3678 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
3679 cause the standalone FancyIndexing directive to logically OR
3680 into any existing IndexOptions settings rather than wiping
3681 them out. [Ken Coar]
3683 *) Changes in ftp proxy: make URL parsing simpler by using the
3685 + Add display of the "current directory" in cases where it's
3686 different from the supplied path (e.g., ftp://user@host/ lives
3687 in /home/user, not in /, therefore clicking on "../" in the
3688 starting directory might send us to /home/).
3689 + When ftp login fails, (esp. when a user name was part of the
3690 URL already), we now return [401 Unauthorized ] to allow the
3691 browser to pop up an authorization dialog. This makes passwords
3692 slightly less visible (they don't appear in the regular log files)
3693 and implements a functionality that other www proxy servers
3697 *) Triggered by the recent "Via:" header changes, the proxy module would
3698 dump core for replies with invalid headers (e.g., duplicate
3699 "HTTP/1.0 200 OK" lines). These errors are now logged and the
3700 core dump is avoided. Also, broken replies are not cached.
3701 [Martin Kraemer] PR#2914
3703 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
3704 plop gmon.out profile data for each child [Doug MacEachern]
3706 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
3707 config.status script to be immune against arguments with whitespaces.
3708 [Yves Arrouye <yves@apple.com>] PR#2866
3710 *) Replace the inlined information grabbing stuff for the configuration
3711 adjustment feature (no --without-confadjust) with calls to a new helper
3712 script `buildinfo.sh' which is both more flexible and already proofed to
3713 be more robust against platform differences. This mainly fixes the
3714 recently occured ``sed: command garbled: ...'' problems.
3715 [Ralf S. Engelschall] PR#2776, PR#2848
3717 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
3718 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
3719 without complains after we recently added the POST feature.
3720 [Ralf S. Engelschall]
3722 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
3723 modules as API functions and we forgot them at the big symbol renaming.
3724 [Ralf S. Engelschall]
3726 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html

3732 *) Add the ability to do POST requests to the ab benchmarking tool.
3733 [Kurt Sussman <kls@best.com>] PR#2871
3735 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
3736 5 to 10 because there are some users out there who always have 5 to 8
3737 variables in one RewriteRule and had to patch mod_rewrite.h for every
3738 release. So 15 should be now more than enough, even for them. (I never
3739 needed more than 4 in my RewriteRules ;-)
3740 [Ralf S. Engelschall]
3742 *) Make the proxy generate and understand Via: headers
3745 *) Change the proxy to use tables instead of array_headers for
3746 the header lines. [Martin Kraemer]
3748 *) Make sure the config.status file is not overridden when just
3749 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
3751 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
3752 provide a way to trace API changes that add functionality but do
3753 not create a compatibility issue for precompiled modules, etc.
3754 See include/ap_mmn.h for more details. [Randy Terbush]
3756 *) Fix suexec installation under `make install root=xxx' situation.
3757 [Ralf S. Engelschall]
3759 *) Extend the output of the -V switch to include the paths of all
3760 compiled-in configuration files, if they were overridden at
3761 compile time, for least astonishment of the user.
3764 *) When READing a request in ExtendedStatus mode, the "old"
3765 vhost, request and client information is not displayed.
3768 *) STATUS is no longer available. Full status information now
3769 run-time configurable using the ExtendedStatus directive.
3772 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
3773 cpu time attacks) in header parsing. Add ap_overlap_tables(),
3774 a function which can be used to perform bulk update operations
3775 on tables in a more efficient manner. [Dean Gaudet]
3777 *) SECURITY: Added compile-time and configurable limits for
3778 various aspects of reading a client request to avoid some simple
3779 denial of service attacks, including limits on maximum request-line
3780 size (LimitRequestLine), number of header fields (LimitRequestFields),
3781 and size of any one header field (LimitRequestFieldsize). Also added
3782 a configurable directive LimitRequestBody for limiting the size of the
3783 request message body. [Roy Fielding]
3785 *) Make status module aware of DNS and logging states, even if
3786 STATUS not defined. [Jim Jagielski]
3788 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
3790 *) Enhance mod_speling so that CheckSpelling can be used in
3791 <Directory> containers and .htaccess files. [Ken Coar]
3793 *) API: new ap_custom_response() function for hooking into the
3794 ErrorDocument mechanism at runtime [Doug MacEachern]
3796 *) API: new ap_uuencode() function [Doug MacEachern]
3798 *) API: scan_script_header_err_core() now "public" and renamed
3799 ap_scan_script_header_err_core() [Doug MacEachern]
3801 *) The 'status' module will now show the process pid's and their
3802 state even without full STATUS accounting. [Jim Jagielski]
3804 *) Restore the client IP address to the error log messages, this
3805 was lost during the transition from 1.2 to 1.3. Add a new
3806 function ap_log_rerror() which takes a request_rec * and
3807 formats it appropriately. [Dean Gaudet] PR#2661
3809 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
3810 whitespace in input lines -- including within quoted strings.
3812 but leading and trailing whitespace should continue to be
3813 stripped [Martin Kraemer]
3815 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
3816 the ugly use of an env. variable and use command-line args for
3817 alternate $PATH. Make more like advanced 'type's as well.
3820 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
3821 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
3822 <alain.st-denis@ec.gc.ca>] PR#2736
3824 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
3826 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
3827 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
3828 directory was renamed to src/os/os2/ for consistency.
3829 [Brian Havard, Ralf S. Engelschall]
3831 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
3832 files (here modules) against other DSO files (here shared libraries).
3833 This is done by determining a subset of LIBS which can be safely used for
3834 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
3835 disabled for all platforms to avoid problems with this (experimental)
3836 rule. But we provide it now for those people how ran into problems and
3837 want to came out by forcing linking against DSOs.

4144 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
4146 *) Improve performance of directory listings (mod_autoindex) by comparing
4147 integer keys (last-modified and size) as integers rather than converting
4148 them to strings first. Also use a set of explicit byte tests rather
4149 than strcmp() to check for parent directory-ness of an entry. Oh, and
4150 make sure the parent directory (if displayed) is *always* listed first
4151 regardless of the sort key. Overall performance winnage should be good
4152 in CPU time, instruction cache, and memory usage, particularly for large
4153 directories. [Ken Coar]
4155 *) Add a tiny but useful goody to APACI's configure script: The generation
4156 of a config.status script (as GNU Autoconf does) which remembers the used
4157 configure command and hence can be used to restore the configuration by
4158 just re-running this script or for remembering the configuration between
4160 [Ralf S. Engelschall]
4162 *) Add httpd -t (test) option for running configuration syntax tests only.
4163 If something is broken it complains and exits with a return code
4164 non-equal to 0. This can be used manually by the user to check the Apache
4165 configuration after editing and is also automatically used by apachectl
4166 on (graceful) restart command to make sure Apache doesn't die on restarts
4167 because of a configuration which is now broken since the last (re)start.
4168 This way `apachectl restart' can be used inside cronjobs without having
4169 to expect Apache to be falling down. Additionally the httpd -t can be run
4170 via `apachectl configtest'.

4340 only for the installation step ("make install"). So make sure the
4341 user is aware of this fact but let him proceed as long as he can.
4342 [Ralf S. Engelschall] PR#2288
4344 *) Renamed three more functions to common ap_ prefix which we missed at the
4345 Big Symbol Renaming because they're #defines and not real C functions:
4346 is_default_port(), default_port(), http_method().
4347 [Ralf S. Engelschall]
4349 *) A zero-length name after a $ in an SSI document should cause
4350 just the $ to be in the expansion. This was broken during the
4351 security fixes in 1.2.5. [Dean Gaudet] PR#1921, 2249
4353 *) Call ap_destroy_sub_req() in ap_add_cgi_vars() to reclaim some
4354 memory. [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2252
4356 *) Fix src/support/httpd.exp (DSO export file which is currently only
4357 used under AIX) because of recent changes to function names.
4358 [Ralf S. Engelschall]
4360 Changes with Apache 1.3b7
4362 *) Make sure a MIME-type can be forced via a RewriteRule even when no
4363 substitution takes place, for instance via the following rule:
4364 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
4365 requested by users in the past to force a single script without a .cgi
4366 extension and outside any cgi-bin dirs to be executed as a CGI program.
4367 [Ralf S. Engelschall] PR#2254
4369 *) A fix for protocol issues surrounding 400, 408, and
4370 414 responses. [Ed Korthof]
4372 *) Ignore MaxRequestsPerChild on WIN32. [Brian Behlendorf]
4374 *) Fix discrepancy in proxy_ftp.c which was causing failures when
4375 trying to connect to certain ftpd's, such as anonftpd.
4376 [Rick Ohnemus <rick@ecompcon.com>]
4378 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
4379 logfile instead of fiddling around itself with child spawning stuff.
4380 [Ralf S. Engelschall]
4382 *) Made RefererIgnore case-insensitive.
4384 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
4387 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
4388 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
4391 *) Improve RFC1413 support. [Bob Beck <beck@bofh.ucs.ualberta.ca>]
4393 *) Fix support script `dbmmanage': It was unable to handle some sort
4394 of passwords, especially passwords with "0" chars.
4395 [Ralf S. Engelschall] PR#2242
4397 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
4398 [Ben Laurie] PR#2238
4400 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
4401 library), so CGI handling has been changed to use Win32 native handles
4402 instead of C file descriptors.
4403 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
4405 *) The proxy cache would store an incorrect content-length in the cached
4406 file copy after a cache update. That resulted in repeated fetching
4407 of the original copy instead of using the cached copy.
4408 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
4410 *) The Makefiles assumed that DSO files are build via $(LD). This
4411 is broken for two reasons: First we never defined at least LD=ld
4412 somewhere to make sure this works (it was silently assumed that most Make
4413 provide a built-in LD definition - ARGL!) and second using the generic LD
4414 variable is not the truth. Instead a special variable named LD_SHLIB is
4415 reasonable because although "ld" is usually the default, the command for
4416 building DSO files can be "libtool" or even "cc" on some systems.
4417 [Ralf S. Engelschall]
4419 *) Replace the AddVersionPlatform directive with ServerTokens which
4420 provides for more control over the format of the Server:
4421 header line. SERVER_SUBVERSION is no longer supported;
4422 all module should use the ap_add_version_component()
4423 API function instead. [Jim Jagielski]
4425 *) Support for the NCR MP/RAS 3.0
4426 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
4428 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
4429 not retrieved in src/Configure and thus was not useable.
4430 [Ralf S. Engelschall]
4432 *) Various Makefile consistency cleanups:
4433 - make OSDIR also automatically be relative to src/ like INCDIR
4434 - SUBDIRS is now generated in src/Makefile only and not in
4435 Makefile.config because it is a local define for this location.
4436 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
4437 any Makefile but make sure that at least the "-K inline" is kept in
4439 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
4440 - updated the dependencies theirself
4441 - removed not existing SHLIB variable from "clean" targets
4442 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
4443 already exists and OBJS_PIC are also just plain objects and have not
4444 directly to do with "shared" things. The only difference is that they
4445 contain PIC. So OBJS_PIC is the more canonical name.
4446 - Updated the Makefile-dependency lines for OBJS_PIC
4447 - Removed the Makefile-dependency line in Configure to avoid double
4449 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
4450 of xxx.lo as GNU libtool does with its PIC objects
4451 - reduce local complexity in modules Makefile.tmpl by moving the last
4452 existing target "depend" to the generation section in Configure, too.
4453 - removed the historical $(SPACER) which was used in the past together
4454 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
4455 is no longer needed.
4456 - force the build and run of the gen_xxx programs under main/ as the
4457 first step before building the objects because it looks cleaner
4458 [Ralf S. Engelschall]
4460 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
4463 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
4466 *) WIN32: Don't force ISAPI headers to finish with \n.
4467 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
4469 *) When opening "configuration" files (like httpd.conf, htaccess
4470 and htpasswd), Apache will not allow them to be non-/dev/null
4471 device files. This closes a DoS hole. At the same time,
4472 we use ap_pfopen to open these files to handle timeouts.
4473 [Jim Jagielski, Martin Kraemer]
4475 *) Apache will now log the reason its httpd children exit if they exit
4476 due to an unexpected signal. (It requires a new porting define,
4477 SYS_SIGLIST, which if defined should point to a list of text
4478 descriptions of the signals available. See PORTING.) [Dean Gaudet]
4480 *) WIN32: chdir() doesn't make sense in a multithreaded environment
4481 like WIN32. Before, Win32 CGI's could have had sporadic failures
4482 if a chdir call from one thread was made between another chdir call
4483 and a spawn in another thread. So, for now don't chdir for CGI scripts
4484 in WIN32. The current CGI "spec" is unclear as to whether it's
4485 necessary. Long-term fix is to either serialize the chdir/spawn combo
4486 or use WIN32 native calls to spawn a process. This temp fix was
4487 necessary to remove this as a showstopper for 1.3's release.
4490 *) Cleanup the suEXEC support in APACI and make it more safe:
4491 1. Add big fat hint in INSTALL about risks and to read the
4492 htdocs/manual/suexec.html document before using the suexec-related
4494 2. Make sure the user has at least provided one --suexec-xxxx option
4495 (specifies suEXEC parameters) in addition to --enable-suexec option.
4496 If only --enable-suexec is given APACI stops with a hint to INSTALL
4497 and htdocs/manual/suexec.html documents.
4498 3. Provide two additional --suexec-xxxx options to make the suEXEC
4499 configuration complete (especially for package maintainers who else
4500 had to patch the source tree) by providing ways to configure minimal
4501 UID/GID and safe PATH, too.
4502 [Ralf S. Engelschall]
4504 *) Cleanup of the `configure --shadow' process:
4505 - make sure the configure script creates its temporary files in the
4506 shadow tree to avoid conflicts with parallel configure runs
4507 - removed unnecessary option "-r" from "rm" call for Makefiles
4508 - make sure the configure scripts creates the shadow-wrapper Makefile
4509 only when no shadow trees already exists
4510 - make sure "make distclean" removes the shadow-wrapper Makefile but only
4511 when no more shadow trees exists
4512 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
4513 as fast (in the past it needed 70sec, now it runs just 38sec)
4514 - make sure CVS does not complain about the created files
4515 Makefille.<gnutriple> and directories src.<gnutriple>
4516 [Ralf S. Engelschall]
4518 *) Added the ap_add_version_component() API routine and the
4519 AddVersionPlatform core directive. The first allows modules to
4520 declare themselves in the Server response header field value,
4521 augmenting the SERVER_SUBVERSION define in the Configuration file
4522 with run-time settings (more useful in a loadable-module environment).
4523 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
4524 into the server version string. [Ken Coar] PR#2056
4526 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
4529 *) Emit the "Accept-Range" header for the default handler.
4530 [Brian Behlendorf] PR#1464
4532 *) Add a note to httpd.conf-dist that apache will on some systems fail
4533 to start when the Group # is set to a negative or large positive value.
4536 *) Make sure the module execution order is correct even when some modules
4537 are loaded under runtime (`LoadModule') via the DSO mechanism:
4538 1. The list of loaded modules is now a dynamically allocated one
4539 and not the original statically list from modules.c
4540 2. The loaded modules are now correctly setup by LoadModule for
4541 later use by the AddModule command.
4542 3. When the DSO mechanism for modules is used APACI's `install'
4543 target now enables all created `LoadModule' lines per default because
4544 this is both already expected by the user _and_ needed to avoid
4545 confusion with the next point and reduces the Makefile.tmpl complexity
4546 4. When the DSO mechanism for modules is used, APACI's `install'
4547 target now additionally makes sure the module list is reconstructed
4548 via a complete `ClearModuleList+AddModule...' entry.
4549 5. The support tool `apxs' now also makes sure an AddModule command
4550 is added in addition to the LoadModule command.
4551 6. The modules.c generation was extended to now contain two
4552 comments to make sure no one is confused by the confusing terminology
4553 of loading/linking (we use load=link+load & link=activate instead of
4554 the obvious load=activate & link=link :-( )
4555 This way now there is no longer a difference under execution time between
4556 statically and dynamically linked modules.
4557 [Ralf S. Engelschall]
4559 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
4560 Big Symbol Renaming. [Ralf S. Engelschall]
4562 *) Add a comment to mod_example.c showing the format of a FLAG command
4565 *) Standardized the time format in mod_status to match that of other
4566 places in the code (e.g. DATE_GMT). PR#1551
4568 *) Fix handling of %Z in timefmt strings for those platforms with no time
4569 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
4572 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
4573 feature compatible with 'UseCanonicalName off' by changing
4574 r->server->server_hostname to ap_get_server_name(). And I changed some
4575 functions which use r->server->port to use ap_get_server_port() instead,
4576 because if there's no Port directive in the config r->server->port is 0.
4579 *) get/set_module_config are trivial enough to be better off inline. Worth
4580 1.5% performance boost. [Dean Gaudet]
4582 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
4583 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
4586 *) [BS2000 security] BS2000 needs an extra authentication to initialize
4587 the task environment to the unprivileged User id. Otherwise CGI scripts
4588 would have a way to gain super user access. [Martin Kraemer]
4590 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
4591 absolute path, only log base name of logging source as is done
4592 in unix. [Martin Kraemer]
4594 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
4595 the encoding type from the Accept-Encoding header (if it's there)
4596 and use it in the response, as that's probably what it'll be expecting.
4597 [Ronald.Tschalaer@psi.ch]
4599 *) Fix to mod_alias: translate_alias_redir is dealing with
4600 a URI, not a filename, so the check for drive letters for win32
4601 and emx is not necessary. [Dean Gaudet]
4603 *) WIN32: Allow .cmd as an executable extension.
4604 [Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146
4606 *) Make Apache header files, and some variables, C++ friendly.
4607 [Michael Anderson's <mka@redes.int.com.mx>]
4609 *) Child processes can now "signal" (by exiting with a status
4610 of APEXIT_CHILDFATAL) the parent process to abort and
4611 shutdown the server if the error in the child process was
4612 fatal enough. [Jim Jagielski]
4614 *) mod_autoindex's find_itme() was sensitive to MIME type case.
4615 [Jim Jagielski] PR#2112
4617 *) Make sure the referer_log and agent_log entries in the default httpd.conf
4618 file are also adjusted for the actual relative installation paths.
4619 [Ralf S. Engelschall] PR#2175
4621 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
4623 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
4626 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
4627 Additionally the checks for finding the vendor DSO library were moved
4628 from mod_so.c to Configure because first it needs $PLAT etc. and second
4629 mod_so already uses an abstraction layer and does not fiddle with the
4630 vendor functions itself.
4631 [Jens-Uwe Mager, Ralf S. Engelschall]
4633 *) PORT: Some optimization defines for NetBSD
4634 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
4636 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
4637 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
4639 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
4640 AIX variants should work fine, too. Even AIX 3.x should work). This is
4641 accomplished by using the free DSO emulation code from Jens-Uwe Mager
4642 which we put into a os/unix/os-dso-aix.c file.
4643 [Ralf S. Engelschall]
4645 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
4646 that we should use NET_SIZE_T == int but the include files force size_t.
4647 [Ralf S. Engelschall]
4649 *) Fix two bugs in select() handling in http_main.c.
4652 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
4653 is unset (as it is in situations like timeouts) where it is unclear
4654 whether errno is set or not. [Martin Kraemer]
4656 *) Just having APACI's localstatedir is too general and not enough for most
4657 of the systems. 1.3b6 again required manual APACI patches by package
4658 maintainers from RedHat and FreeBSD because for their filesystem layout a
4659 little bit more flexibility in configuring the paths is needed. Hence we
4660 provide three additional configure options (--runtimedir, --logfiledir,
4661 --proxycachedir) which now can be used for more granular adjustments if
4662 --localstatedir is not enough to fit the particular needs. As a nice
4663 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
4664 [Ralf S. Engelschall]
4666 *) Make the install root for "make install" in APACI's Makefile overrideable
4667 by package authors. This way we are even more friendly to package
4668 maintainers (especially Debian and RedHat) who build for the real prefix
4669 via "configure --prefix=/<real>" but use a different local prefix via
4670 "make root=/tmp/apache install" for rolling the package without bristling
4671 the target location on their system.
4672 [Ralf S. Engelschall]
4674 *) Workaround sed limitations in APACI's configure script by now
4675 substituting in chunks of 50 commands (because for instance HPUX's vendor
4676 sed has a limit of max. 98 commands)
4677 [Ralf S. Engelschall] PR#2136
4679 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
4680 [Ralf S. Engelschall] PR#2140
4682 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
4683 RENAMING process because they are defined as pre-processor macros instead
4684 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
4685 [Ralf S. Engelschall]
4687 *) Workaround braindead AWK's when generating ap_config.h: The split() and
4688 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
4689 [Ralf S. Engelschall] PR#2139
4691 *) Various bugfixes and cleanups for the APACI configure script:
4692 o fix IFS handling for _nested_ situation
4693 o fix Perl interpreter search: take first one found instead of last one
4694 o fix DSO consistency check
4695 o print error messages to stderr instead of stdout
4696 o add install-quiet for --shadow situation to Makefile stub
4697 o reduce complexity by avoiding sed-hacks for rule and module list loops
4698 [Ralf S. Engelschall]
4700 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
4702 *) Make sure the input field separator (IFS) shell variable is explicitly
4703 initialized correctly before _every_ `for' loop and also restored after
4704 the loops. [Ralf S. Engelschall]
4706 *) Make sure that "make install" doesn't overwrite the `mime.types' and
4707 `magic' files from an existing Apache installation. Because people often
4708 customize these for own MIME and content types.
4709 [Ralf S. Engelschall]
4711 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
4712 [Peter Galbavy, Ralf S. Engelschall] PR#2109
4714 *) Fix the path to the ScoreBoardFile in the install-config target, too.
4715 [Ralf S. Engelschall] PR#2105
4717 *) Let "configure" clear out the users parameters (provided as shell
4718 variables) to avoid side-effects in "src/Configure" when the user
4719 exported them (which is not needed, but some users do it).
4720 [Ralf S. Engelschall] PR#2101
4722 *) Provide backward compatibility from some old src/Configuration.tmpl
4723 parameter names to the canonical Autoconf-style shell variable names. For
4724 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
4725 but a hint message is displayed. [Ralf S. Engelschall]
4727 *) Make sure that "make install" doesn't overwrite the DocumentRoot and
4728 CGI scripts from an existing Apache installation.
4729 [Ralf S. Engelschall, Jim Jagielski] PR#2084
4731 *) Make `configure --compat' more "compatible" by first
4732 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
4733 second by making sure the "avoid-bristling-suffix" /apache is not
4734 appended to sysconfdir, datadir, localstatedir and includedir when
4735 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]
4737 *) NeXT required strdup() in support/logresolve.c
4738 [Francisco Tomei <fatomei@sandburg.unm.edu>] PR#2082
4740 *) AIX required sys/select.h in support/ab.c

4743 *) Fix the path to the MimeMagicFile in the install-config target, too.
4744 [Ralf S. Engelschall] PR#2089
4746 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
4748 *) If you start apache with the -S command line option it will dump
4749 out the parsed vhost settings. This is useful for folks trying
4750 to figure out what is wrong with their vhost configuration.
4751 (Other dumps may be added in the future.) [Dean Gaudet]
4753 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
4754 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
4757 *) Because /usr/local/apache is the default prefix the ``configure
4758 --compat'' option no longer has to set prefix, again. This way the
4759 --compat option honors a leading --prefix option. [Lars Eilebrecht]
4761 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
4762 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
4763 to avoid "discard const" warnings. [Ralf S. Engelschall]
4765 *) If a specific handler is set for a file yet the request still
4766 ends up being handled by the default handler, log an error
4767 message before handling it. This catches things such as trying
4768 to use SSIs without mod_include enabled. [Marc Slemko]
4770 *) Fix error logging for the startup case where ap_log_error() still uses
4771 stderr as the target. Now the default log level is honored here, too.
4772 [Ralf S. Engelschall]
4774 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
4775 long" errors when generating the MODULES entry for src/Makefile
4776 [Ben Hyde, Ralf S. Engelschall]
4778 *) Make sure src/Configure doesn't complain about the old directory
4779 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
4781 Changes with Apache 1.3b6
4783 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
4785 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
4786 interface via the similar but proprietary HP/UX shl_xxx-style system
4787 calls. [Ralf S. Engelschall]
4789 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
4790 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
4791 Make. [Ralf S. Engelschall]
4793 *) ++++ THE BIG SYMBOL RENAMING ++++
4794 To avoid symbol clashes with third-party code compiled into the server,
4795 we globally applied the prefix "ap_" to the following classes of
4797 - Apache provided general functions (e.g., ap_cpystrn)
4798 - Public API functions (e.g., palloc, bgets)
4799 - Private functions which we can't make static (because of
4800 cross-object usage) but should be (e.g., new_connection)
4801 For backward source compatibility a new header file named compat.h was
4802 created which provides defines for the old symbol names and can be used
4803 by third-party module authors.
4806 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
4807 problem under SVR4 is that there is no command flag to force the linker
4808 to export the global symbols of the httpd executable therewith they are
4809 available to the DSO's. Instead of problematic hacks like creating a
4810 dummy.so file (containing dummy references to all global symbols) the
4811 httpd binary is linked against, we use a clean trick stolen from Perl 5:
4812 Placing the Apache core code itself into a DSO library named libhttpd.so.
4813 This way the global symbols _HAVE_ to be exported and thus are available
4814 to any manually loaded DSO's under runtime. To reduce the impact to the
4815 user to null we go even further and create a stub httpd executable which
4816 automatically keeps track of the DSO library loading itself and thus
4817 hides the complete mechanism from the user. Although the generation of
4818 this DSO library is automatically triggered for platforms which
4819 essentially need it (mostly all SVR4-derivates) it can be also enabled
4820 manually via the Rule SHARED_CORE. This can be interesting in the future
4821 where we perhaps exploit this libhttpd.so mechanism for providing nifty
4822 features like graceful upgrades, or whatever.
4823 [Ralf S. Engelschall, Martin Kraemer]
4825 *) Build the libraries before building the rest of the tools. [Ben Hyde]
4827 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
4828 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
4829 conventions while "clean" removes only stuff created by "all" targets,
4830 "distclean" additionally removes the stuff from the configuration
4831 process. This way "make distclean" (hence the name) provides a fresh
4832 source tree as it was for distribution.
4833 [Ralf S. Engelschall]
4835 *) Allow top-level (APACI) Makefile to break on build errors
4836 the same way the src/ subtree Makefiles breaks on them by replacing the
4837 initial APACI sed-subdir-display-kludge with a more clean
4838 variable-passing-solution: variable SDP can optionally hold the subdir
4839 prefix which is consistently used for displaying the subdir movement.
4840 This way even the top-level Makefile can stop correctly on errors as the
4841 user expects. [Ralf S. Engelschall]
4843 *) Fixed ordering of argument checks for RewriteBase directive.
4844 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
4846 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
4847 indicating that a module is being compiled for dynamic loading. Also
4848 remove #define IS_MODULE from modules and add SHARED_MODULE define
4849 to the mak/dsp files. [Alexei Kosut]
4851 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
4852 since we are now logging APLOG_WARNING by default. [Roy Fielding]
4854 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
4856 *) Add documentation file and src/Configuration.tmpl entry for the
4857 experimental mod_mmap_static module. Because although it is and marked as
4858 an experimental one it is distributed and thus should be documented and
4859 prepared for configuration the same way as all others modules.
4860 [Ralf S. Engelschall]
4862 *) Add query (-q) option to apxs support tool to be able to manually query
4863 specific settings from apxs. This is needed for instance when you
4864 manually want to access Apache's header files and you need to assemble
4865 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
4866 [Ralf S. Engelschall]
4868 *) Now src/Configure uses a fallback strategy for the shared object support
4869 on platforms where no explicit information is available: If a Perl
4870 installation exists we ask it about its shared object support and if it's
4871 the dlopen-style one we shamelessly guess the compiler and linker flags
4872 for creating shared objects from Perls knowledge. Of course, the user is
4873 warning about what we are doing and informed that he should send us
4874 the guessed flags when they work. [Ralf S. Engelschall]
4876 *) Provide APACI --without-support option to be able to disable the build
4877 and installation of the support tools from the src/support/ area.
4878 Although its useful to have these installed per default we should provide
4879 a way to compile and install without them for backward-compatibility.
4880 [Ralf S. Engelschall]
4882 *) Add of the new APache eXtenSion (apxs) support tool for building and
4883 installing modules into an _already installed_ Apache package through the
4884 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
4885 this approach actually doesn't need the Apache source tree. The
4886 (APACI-installed) server package is enough, because this now includes the
4887 Apache C header files (PREFIX/include) and the new APXS tool
4888 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
4889 module authors to build their Apache modules _OUTSIDE_ the Apache source
4890 tree while avoiding them to fiddle around with the totally platform
4891 dependend way of compiling DSO files. The tool supports all ranges of
4892 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
4893 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
4894 on-the-fly generate a minimalistic Makefile and sample module for the
4895 first step to provide both a quick success event and to demonstrate the
4896 APXS mechanism to module authors. [Ralf S. Engelschall]
4898 *) Fix core dumps in use of CONNECT in proxy.
4899 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
4901 *) Modify the log directives in httpd.conf-dist files to use CustomLog
4902 so that users have examples of how CustomLog can be used.
4905 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
4906 the Apache distribution tree. Until Apache 1.3 there was no real
4907 out-of-the-box batch-capable build and installation procedure for the
4908 complete Apache package. This is now provided by a top-level "configure"
4909 script and a corresponding top-level "Makefile.tmpl" file. The goal is
4910 to provide a GNU Autoconf-style frontend which is capable to both drive
4911 the old src/Configure stuff in batch and additionally installs the
4912 package with a GNU-conforming directory layout. Any options from the old
4913 configuration scheme are available plus a lot of new options for flexibly
4914 customizing Apache. [Ralf S. Engelschall]
4916 *) The floating point ap_snprintf code wasn't threadsafe.
4917 Had to remove the HAVE_CVT macro in order to do threadsafe
4918 calling of the ?cvt() floating point routines. [Dean Gaudet]
4920 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
4922 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
4923 [Jim Jagielski] PR#1901
4925 *) BUG: Configure was using TCC and CC inconsistently. Make sure
4926 Configure knows which CC we are using. [Jim Jagielski]
4928 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
4929 was defined in a parent directory. [Lars Eilebrecht]
4931 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
4932 a generic printf-style routine that can call arbitrary output
4933 routines. Use this to replace http_bprintf.c. Add new routines
4934 psprintf(), pvsprintf() which allocate the exact amount of memory
4935 required for a string from a pool. Use psprintf() to clean up
4936 various bits of code which used ap_snprintf()/pstrdup().
4939 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
4940 ap_snprintf() has different semantics and formatting codes than
4941 snprintf(). [Dean Gaudet]
4943 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
4944 is necessary on at least Solaris where the /etc/rc?.d scripts
4945 are run with these signals ignored, and "SIG_IGN" settings are
4946 maintained across exec().
4947 [Rein Tollevik <reint@sys.sol.no>] PR#2009
4949 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
4950 used instead of lstat() and thus this flag didn't work as expected.
4951 [Rein Tollevik <reint@sys.sol.no>] PR#2010
4953 *) Fix the proxy pass-through feature of mod_rewrite for the case of
4954 existing QUERY_STRING now that mod_proxy was recently changed because of
4955 the new URL parsing stuff. [Ralf S. Engelschall]
4957 *) A few changes to scoreboard definitions which helps gcc generate
4958 better code. [Dean Gaudet]
4960 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
4961 be a signed bitfield. So mark a few bitfields as signed to
4962 ensure correct code. [Dean Gaudet]
4964 *) The default for HostnameLookups was changed to Off, but there
4965 was a problem and it wasn't taking effect. [Dean Gaudet]
4967 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
4970 *) After a SIGHUP the listening sockets in the parent weren't
4971 properly marked for closure on fork().
4972 [Jürgen Keil <jk@tools.de>] PR#2000
4974 *) Allow %2F in two situations: 1) it is in the query part of the URI,
4975 therefore not exposed to %2F -> '/' translations and 2) the request
4976 is a proxy request, so we're not dealing with a local resource anyway.
4977 Without this, the proxy would fail to work for any URL's with
4978 %2f in them (occurs quite often in
4979 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
4981 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
4983 *) Make the shared object compilation command more portable by avoiding
4984 the direct combination of `-c' & `-o' which is not honored by some
4985 compilers like UnixWare's cc. [Ralf S. Engelschall]
4987 *) WIN32: the proxy was creating filenames missing the last four
4988 characters. While this normally doesn't stop anything from
4989 working, it can result in extra collisions.
4990 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
4992 *) Now mod_proxy uses the response string (in addition to the response status
4993 code) from the already used FTP SIZE command to setup the Content-Length
4994 header if available. [Ralf S. Engelschall] PR#1183
4996 *) Reanimated the (still undocumented) proxy receive buffer size directive:
4997 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
4998 name was really too generic, added documentation for this directive to
4999 the mod_proxy.html and corrected the hyperlink to it in the
5000 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
5002 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
5003 faster [Martin Kraemer]
5005 *) Make Configure die when you give it an unknown command switch.
5008 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
5009 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
5010 and per default compiled support programs have manual pages - just to
5011 document our stuff a little bit more and to be able to do really
5012 Unix-like installations ;-) [Ralf S. Engelschall]
5014 *) Major cleanups to the Configure script to make it and its generated
5015 Makefiles again readable and maintainable: add SRCDIR option, removed
5016 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
5017 generated sections, consequently added Makefile headers with inheritance
5018 information, added subdir movement messages for easier following where
5019 the build process currently stays (more verbose then standard Make, less
5020 verbose than GNU make), same style to comments in the Configure script,
5021 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
5023 *) Add the new ApacheBench program "ab" to src/support/: This is derived
5024 from the ZeusBench benchmarking program and can be used to determine the
5025 response performance of an Apache installation. This version is
5026 officially licensed with Zeus Technology, Ltd. See the license agreement
5027 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
5028 [Ralf S. Engelschall]
5030 *) API: Various core functions that are definately not part of the API
5031 have been made static, and a few have been marked API_EXPORT. Still
5032 more have been marked CORE_EXPORT and are not intended for general
5033 use by modules. [Doug MacEachern, Dean Gaudet]
5035 *) mod_proxy was not clearing the Proxy-Connection header from
5036 requests; now it does. This did not violate any spec, however
5037 causes poor interactions when you are talking to remote proxies.
5038 [Marc Slemko] PR#1741
5040 *) Various cleanups to the command line interface and manual pages.
5041 [Ralf S. Engelschall]
5043 *) cfg_getline() was not properly handling lines that did not end
5044 with a line termination character. [Marc Slemko] PR#1869, 1909
5046 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
5048 *) Clean up some undocumented behavior of mod_setenvif related to
5049 "merging" two SetEnvIf directives when they match the same header
5050 and regex. Document that mod_setenvif will perform comparisons in
5051 the order they appear in the config file. Optimize mod_setenvif by
5052 doing more work at config time rather than at runtime.
5055 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
5056 to allow for modules to overrule them and to reduce redefinition
5057 warnings [Jim Jagielski]
5059 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
5062 *) Making the hard-coded cross-module function call mime_find_ct() (from
5063 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
5064 checking is really called even for proxy requests except for URLs with
5065 HTTP schemes (because there we can optimize by not running the type
5066 checking hooks due to the fact that the proxy gets the MIME Content-type
5067 from the remote host later). This change cleans up mod_mime by removing
5068 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
5069 especially unbundles mod_proxy and mod_mime. This way they both now can
5070 be compiled as shared objects and are no longer tied together.
5071 [Ralf S. Engelschall]
5073 *) util.c cleanup and speedup. [Dean Gaudet]
5075 *) API: Clarification, pstrndup() will always copy n bytes of the source
5076 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
5078 *) Mark module command_rec and handler_rec structures const so that they
5079 end up in the read-only data section (and are friendlier to systems
5080 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
5082 *) Add check to the "Port" directive to make sure the specified
5083 port is in the appropriate range. [Ben Hyde]
5085 *) Performance improvements to invoke_handler().
5086 [Dmitry Khrustalev <dima@bog.msu.su>]
5088 *) Added support for building shared objects even for library-style modules
5089 (which are built from more than one object file). This now provides the
5090 ability to build mod_proxy as a shared object module. Additionally
5091 modules like mod_example are now also supported for shared object
5092 building because the generated Makefiles now no longer assume there is at
5093 least one statically linked module. [Ralf S. Engelschall]
5095 *) API: Clarify usage of content_type, handler, content_encoding,
5096 content_language and content_languages fields in request_rec. They
5097 must always be lowercased; and the strings pointed to shouldn't
5098 be modified (you must copy them to modify them). Fix a few bugs
5099 related to this. [Dean Gaudet]
5101 *) API: Clarification: except for RAW_ARGS, all command handlers can
5102 treat the char * parameters as permanent, and modifiable. There
5103 is no need to pstrdup() them. Clean up some needless pstrdup().
5106 *) Now mod_so keeps track of which module shared objects with which names
5107 are loaded and thus avoids multiple loading and unloading and irritating
5108 error_log messages. [Ralf S. Engelschall]
5110 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
5111 environment variable in the apache core. But that tweaking interferes
5112 with mod_setenv. So don't tweak if the user has specified an explicit
5113 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
5115 *) rputs() did not calculate r->sent_bodyct properly.
5116 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
5118 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
5119 name, or left unset if this value is unavailable. Apache was setting
5120 it to the IP address when unavailable.
5121 [Tony Finch <fanf@demon.net>] PR#1925
5123 *) Various improvements to the configuration and build support for compiling
5124 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
5125 OSF1 support with GCC and vendor compilers was added. This way shared
5126 object support is now provided out-of-the-box for FreeBSD, Linux,
5127 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
5128 [Ralf S. Engelschall]
5130 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
5131 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
5132 and USE_OS2_SCOREBOARD. [Dean Gaudet]
5134 *) Fix one more special locking problem for RewriteMap programs in
5135 mod_rewrite: According to the documentation of flock(), "Locks are on
5136 files, not file descriptors. That is, file descriptors duplicated
5137 through dup(2) or fork(2) do not result in multiple instances of a lock,
5138 but rather multiple references to a single lock. If a process holding a
5139 lock on a file forks and the child explicitly unlocks the file, the
5140 parent will lose its lock.". To overcome this we have to make sure the
5141 RewriteLock file is opened _AFTER_ the childs were spawned which is now
5142 the case by opening it in the child_init instead of the module_init API
5143 hook. [Ralf S. Engelschall] PR#1029
5145 *) Change to Location and LocationMatch semantics. LocationMatch no
5146 longer lets a single slash match multiple adjacent slashes in the
5147 URL. This change is for consistency with RewriteRule and
5148 AliasMatch. Multiple slashes have meaning in URLs that they do
5149 not have in (some) filesystems. Location on the other hand can
5150 be considered a shorthand for a more complicated regex, and it
5151 does match multiple slashes with a single slash -- which is
5152 also consistent with the Alias directive.
5153 [Dean Gaudet] related PR#1440
5155 *) Fix bug with mod_mime_magic causing certain files, including files
5156 of length 0, to result in no response from the server.
5159 *) The Configure script now generates src/include/ap_config.h which
5160 contains the set of defines used when Apache is compiled on a platform.
5161 This file can then be included by external modules before including
5162 any Apache header files in case they are being built separately from
5163 Apache. Along with this change, a couple of minor changes were
5164 made to make Apache's #defines coexist peacefully with any autoconf
5165 defines an external module might have. [Rasmus Lerdorf]
5167 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
5168 but without any RewriteXXXXX directives. Here mod_rewrite is given no
5169 chance by the API to initialize its per-server configuration and thus
5170 receives the wrong one from the main server. This is now avoided by
5171 remembering the server together with the config structure while
5172 configuring and later assuming there is no config when we see a
5173 difference between the remembered server and the one calling us.
5174 [Ralf S. Engelschall] PR#1790
5176 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
5177 is automatically disabled under configure time when the dbm_xxx functions
5178 are not available. Second, two heavy source code errors in the DBM
5179 support code were fixed. This makes DBM RewriteMap's usable again after
5180 a long time of brokenness. [Ralf S. Engelschall] PR#1696
5182 *) Now all configuration files support Unix-style line-continuation via
5183 the trailing backslash ("\") character. This enables us to write down
5184 complex or just very long directives in a more readable way. The
5185 backslash character has to be really the last character before the
5186 newline and it has not been prefixed by another (escaping) backslash.
5187 [Ralf S. Engelschall]
5189 *) When using ProxyPass the ?querystring was not passed correctly.
5190 [Joel Truher <truher@wired.com>]
5192 *) To deal with modules being compiled and [dynamically] linked
5193 at a different time from the core, the SERVER_VERSION and
5194 SERVER_BUILT symbols have been abstracted through the new
5195 API routines apapi_get_server_version() and apapi_get_server_built().
5198 *) WIN32: Preserve trailing slash in canonical path (and hence
5199 in PATH_INFO). [Paul Sutton, Ben Laurie]
5201 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
5202 depending on the rev of Solaris and what mixture of modules
5203 are in use. So it has been disabled, and Solaris is back to
5204 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
5205 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
5206 up static content only servers. Or it may fail unpredictably.
5207 [Dean Gaudet] PR#1779, 1854, 1904
5209 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
5212 *) API: Rewrite of absoluteURI handling, and in particular how
5213 absoluteURIs match vhosts. Unless a request is a proxy request, a
5214 "http://host" url is treated as if a similar "Host:" header had been
5215 supplied. This change was made to support future HTTP/1.x protocols
5216 which may require clients to send absoluteURIs for all requests.
5218 In order to achieve this change subtle changes were made to the API. In a
5219 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
5220 that the unmodified uri can be retrieved easily. r->proxyreq is not set
5221 by the core, modules must set it during the post_read_request or
5222 translate_names phase.
5224 Plus changes to the virtualhost test suite for absoluteURI testing.
5226 This fixes several bugs with the proxy proxying requests to vhosts
5227 managed by the same httpd.
5230 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
5231 code from mod_rewrite. The vhost matching is now performed by a
5232 globally available function matches_request_vhost(). [Dean Gaudet]
5234 *) Reduce memory usage, and speed up ServerAlias support. As a
5235 side-effect users can list multiple ServerAlias directives
5236 and they're all considered.

5243 *) Make \\ behave as expected. [Ronald.Tschalaer@psi.ch]
5245 *) Add the `%a' construct to LogFormat and CustomLog to log the client IP
5246 address. [Todd Eigenschink <eigenstr@mixi.net>] PR#1885
5248 *) API: A new source module main/util_uri.c; It contains a routine
5249 parse_uri_components() and friends which breaks a URI into its component
5250 parts. These parts are stored in a uri_components structure called
5251 parsed_uri within each request_rec, and are available to all modules.
5252 Additionally, an unparse routine is supplied which re-assembles the URI
5253 components back to an URI, optionally hiding the username:password@ part
5254 from ftp proxy requests, and other useful routines. Within the structure,
5255 you find on a ready-for-use basis:
5256 scheme; /* scheme ("http"/"ftp"/...) */
5257 hostinfo; /* combined [user[:password]@]host[:port] */
5258 user; /* user name, as in http://user:passwd@host:port/ */
5259 password; /* password, as in http://user:passwd@host:port/ */
5260 hostname; /* hostname from URI (or from Host: header) */
5261 port_str; /* port string (integer representation is in "port") */
5262 path; /* the request path (or "/" if only scheme://host was given) */
5263 query; /* Everything after a '?' in the path, if present */
5264 fragment; /* Trailing "#fragment" string, if present */
5265 This is meant to serve as the platform for *BIG* savings in
5266 code complexity for the proxy module (and maybe the vhost logic).
5269 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
5270 ${map:key}) available for all location where a string is created in
5271 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
5272 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
5273 possible expansions are consequently usable at all string creation
5274 locations. [Ralf S. Engelschall]
5276 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
5277 and not 1) and the per-virtual-server merging of directives. Now all
5278 directives except `RewriteEngine' and `RewriteOption' are either
5279 completely overridden (default) or completely inherited (when
5280 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325
5282 *) Fix `RewriteMap' program lookup in situations where such maps are
5283 defined but disabled (`RewriteEngine off') in per-server context.
5284 [Ralf S. Engelschall] PR#1431
5286 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause
5287 server to bind to port 0 rather than 80. [Dean Gaudet]
5289 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
5290 (like SunOS and FreeBSD) which don't accept the locking of pipes
5291 directly. A new directive RewriteLock is introduced which can be used to
5292 setup a separate locking file which then is used for synchronization.

5304 a username can contain when trying to expand it via /etc/passwd.
5305 [Ralf S. Engelschall]
5307 *) The mod_setenvif BrowserMatch backwards compatibility command did not
5308 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
5310 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
5311 type but with a special post-processing for the looked-up value: It
5312 parses it into alternatives according to `|' chars and then only one
5313 particular alternative is chosen randomly (this is an essential
5314 functionality needed for balancing between backend-servers when using
5315 Apache as a Reverse Proxy. The looked up value here is a list of
5316 servers). Second, `int' with the built-in maps named `tolower' and
5317 `toupper' which can be used to map URL parts to a fixed case (this is an
5318 essential feature to fix the case of server names when doing mass
5319 virtual-hosting with the help of mod_rewrite instead of using
5320 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
5321 Jay Soffian <jay@cimedia.com>] PR#1631
5323 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
5324 This directive lets Apache adjust the URL in Location-headers on HTTP
5325 redirect responses sent by the remote server. This way the virtually
5326 mapped area is no longer left on redirects and thus by-passed which is
5327 especially essential when running Apache as a reverse proxy.

5330 *) Hide Proxy-Authorization from CGI/SSI/etc just like Authorization is
5331 hidden. [Alvaro Martinez Echevarria]
5333 *) Apache will, when started with the -X (single process) debugging flag,
5334 honor the SIGINT or SIGQUIT signals again now. This capability got lost
5335 a while ago during OS/2 signal handling changes.

5345 *) Use SA_RESETHAND or SA_ONESHOT when installing the coredump handlers.
5346 In particular the handlers could trigger themselves into an infinite
5347 loop if RLimitMem was used with a small amount of memory -- too small
5348 for the signal stack frame to be set up. [Dean Gaudet]

5366 processor. httpd children now unbind themselves from that cpu
5367 and re-bind to one selected at random via bindprocessor()
5370 *) Linux 2.0 and above implement RLIMIT_AS, RLIMIT_DATA has almost no
5371 effect. Work around it by using RLIMIT_AS for the RLimitMEM

5377 *) Previously Apache would permit </Files> to end <FilesMatch> (and
5378 similary for Location and Directory), now this is diagnosed as an
5379 error. Improve error messages for mismatched sections (<Files>,
5380 <FilesMatch>, <Directory>, <DirectoryMatch>, ...).

5383 *) <Files> is not permitted within <Location> (because of the

5425 *) Sort out problems with canonical filename handling happening too late.
5426 [Dean Gaudet, Ben Laurie]
5428 Changes with Apache 1.3b4
5430 *) The module structure was modified to include a *dynamic_load_handle
5431 in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
5432 has been bumped accordingly. [Paul Sutton]
5434 *) All BrowserMatch directives mentioned in
5435 htdocs/manual/known_client_problems.html are in the default
5436 configuration files. [Lars Eilebrecht]
5438 *) MiNT port update. [Jan Paul Schmidt]
5440 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
5441 equivalent, similarly for x-compress and compress. Apache
5442 now ignores a leading x- when comparing encodings. It also
5443 preserves the encoding the client requests (for example if
5444 it requests x-gzip, then Apache will respond with x-gzip
5445 in the Content-Encoding header).
5446 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1772
5448 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
5450 *) Added mod_so module to support dynamic loading of modules on Unix
5451 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
5452 instead of AddModule in Configuration to build shared modules
5453 [Sameer Parekh, Paul Sutton]
5455 *) Minor cleanups to r->finfo handling in some modules.
5458 *) Abstract read()/write() to ap_read()/ap_write().
5459 Makes it easier to add other types of IO code such as SFIO.
5462 *) API: Generalize default_port manipulations to make support of
5463 different protocols easier. [Ben Laurie, Randy Terbush]
5465 *) There are many cases where users do not want Apache to form
5466 self-referential urls using the "canonical" ServerName and Port.
5467 The new UseCanonicalName directive (default on), if set to off
5468 will cause Apache to use the client-supplied hostname and port.
5469 API: Part of this change required a change to the construct_url()
5470 prototype; and the addition of get_server_name() and
5472 [Michael Douglass <mikedoug@texas.net>, Dean Gaudet]
5473 PR#315, 459, 485, 1433
5475 *) Yet another rearrangement of the source tree.. now all the common
5476 header files are in the src/include directory. The -Imain -Iap
5477 references in Makefiles have been changed to the simpler -Iinclude
5478 instead. In addition to simplifying the build a little bit, this
5479 also makes it clear when a module is referencing something in a
5480 other than kosher manner (e.g., the proxy including mod_mime.h).
5481 Module-private header files (the proxy, mod_mime, the regex library,
5482 and mod_rewrite) have not been moved to src/include; nor have
5483 the OS-abstraction files. [Ken Coar]
5485 *) Fix a bug where r->hostname didn't have the :port stripped
5486 from it. [Dean Gaudet]
5488 *) Tweaked the headers_out table size, and the subprocess_env
5489 table size guess in rename_original_environment(). Added
5490 MAKE_TABLE_PROFILE which can help discover make_table()
5491 calls that use too small an initial guess, see alloc.c.
5494 *) Options and AllowOverride weren't properly merging in the main
5495 server setting inside vhosts (only an issue when you have no
5496 <Directory> or other section containing an Options that affects
5497 a request). Options +foo or -foo in the main_server wouldn't
5498 affect the main_server's lookup defaults. [Dean Gaudet]
5500 *) Variable 'cwd' was being used pointlessly before being set.
5503 *) r->allowed handling cleaned up in the standard modules.
5506 *) Some case-sensitivity issues cleaned up to be consistent with
5507 RFC2068. [Dean Gaudet]
5509 *) SIGURG doesn't exist everywhere.
5510 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
5512 *) mod_unique_id was erroneously generating a second unique id when
5513 an internal redirect occured. Such redirects occur, for example,
5514 when processing a DirectoryIndex match. [Dean Gaudet]
5516 *) API: table_add, table_merge, and table_set include implicit pstrdup()
5517 of the key and value. But in many cases this is not required
5518 because the key/value is a constant, or the value has been built
5519 by pstrcat() or other similar means. New routines table_addn,
5520 table_mergen, and table_setn have been added to the API, these
5521 routines do not pstrdup() their arguments. The core code and
5522 standard modules were changed to take advantage of these routines.
5523 The resulting server is up to 20% faster in some situations.
5525 Note that it is easy to get code subtly wrong if you pass a key/value
5526 which is in a pool other than the pool of the table. The only
5527 safe thing to do is to pass key/values which are in the pool of
5528 the table, or in one of the ancestors of the pool of the table.
5529 i.e. if the table is part of a subrequest, a value from the main
5530 request's pool is OK since the subrequest pool is a sub_pool of the
5531 main request's pool (and therefore has a lifespan at most as long as
5532 the main pool). There is debugging code which can detect improper
5533 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
5534 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
5536 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
5537 which don't exist on disk more gracefully; handles vhosts properly.
5538 Update documentation to reflect the code -- if there's no
5539 MimeMagicFile directive then the module is not enabled.
5542 *) PORT: Some older *nix dialects cannot automatically start scripts
5543 which begin with a #! interpreter line (the shell starts the scripts
5544 appropriately on these platforms). Apache now supports starting of
5545 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
5546 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
5549 *) API: "typedef array_header table" removed from alloc.h, folks should
5550 have been writing to use table as if it were an opaque type, but even
5551 some standard modules got this wrong. By changing the definition
5552 to "typedef struct table table" module authors will receive compile
5553 time warnings that they're doing the wrong thing. This change
5554 facilitates future changes with more sophisticated table
5555 structures. Specifically, module authors should be using table_elts()
5556 to get access to an array_header * for the table. [Dean Gaudet]
5558 *) API: Renamed new_connection() to avoid namespace collision with LDAP
5559 library routines. [Ken Coar, Rasmus Lerdorf]
5561 *) WIN32: mod_speling is now available on the Win32 platform.
5564 *) For clarity the following compile time definition was changed:
5566 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
5568 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
5569 and not be a general notice that the OS has mmap(). Now the
5570 HAVE_MMAP/SHMGET #defines strictly are informational that the
5571 OS has that method of shared memory; the type to use for
5572 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
5573 and USE_SHMGET_SCOREBOARD). This allows outside modules to
5574 determine if shared memory is available and allows Apache
5575 to determine the best method to use for the scoreboard.
5578 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
5579 as do various earlier versions. It should be safe on all versions.
5580 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
5581 the slack code. A few other cleanups for Unixware.

5584 *) PORT: A/UX can handle single-listen accepts without mutex
5585 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
5587 *) When die() happens we need to eat any request body if one exists.
5588 Otherwise we can't continue with a keepalive session. This shows up
5589 as a POST problem with MSIE 4.0, typically against pages which are
5590 authenticated. [Roy Fielding] PR#1399
5592 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
5593 header will be passed to CGIs. This is generally a security hole, so

5601 *) suexec errors now include the errno/description. [Marc Slemko] PR#1543
5603 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
5604 The choice of flock vs. fcntl was made based on timings which showed that
5605 even on non-NFS, non-exported filesystems fcntl() was an order of
5606 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
5607 that single socket users will see no difference. [Dean Gaudet] PR#467
5609 *) "File does not exist" error message was erroneously including the
5610 errno. [Marc Slemko]
5612 *) Improve the warning message generated when a client drops the
5613 connection (hits stop button, etc.) during a send. [Roy Fielding]
5615 *) Defining GPROF will disable profiling in the parent and enable it

5617 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
5619 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.

5629 *) Some const declarations in mod_imap.c that were added for debugging
5630 purposes caused some compilers heartburn without adding any
5631 significant value, so they've been removed. [Ken Coar]
5633 *) The src/main/*.h header files have had #ifndef wrappers added to
5634 insulate them against duplicate calls if they get included through
5635 multiple paths (e.g., in .c files as well as other .h files).
5638 *) The libap routines now have a header file for their prototypes,
5639 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
5641 *) mod_autoindex with a plaintext header file would emit the <PRE>
5642 start-tag before the HTML preamble, rather than after the preamble
5643 but before the header file contents. [John Van Essen <jve@gamers.org>]
5646 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
5647 only an issue on systems without a MAXDNAME define or where
5648 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
5650 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
5651 is used to read various types of files such as htaccess and
5652 htpasswd files. [Marc Slemko]
5654 *) SECURITY: Ensure that the buffer returned by ht_time is always
5655 properly null terminated. [Marc Slemko]
5657 *) The "Connection" header could be sent back with multiple "close"
5658 tokens. Not an error, but a waste.
5659 [Ronald.Tschalaer@psi.ch] PR#1683
5661 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
5662 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
5664 *) "basic" auth needs a case-insensitive comparison.
5665 [Ronald.Tschalaer@psi.ch] PR#1666
5667 *) For maximum portability, the environment passed to CGIs should
5668 only contain variables whose names match the regex
5669 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
5670 underscores over any character outside the regex. This
5671 affects HTTP_* variables, in a way that should be backward
5672 compatible for all the standard headers; and affects variables
5673 set with SetEnv/BrowserMatch and similar directives.
5676 *) mod_speling returned incorrect HREF's when an ambigous match

5759 *) send_fd_length() did not calculate total_bytes_sent properly.
5760 [Ben Reser <breser@regnow.com>] PR#1366
5762 *) The bputc() macro was not properly integrated with the chunking
5763 code; in many cases modules using bputc() could cause completely
5764 bogus chunked output. (Typically this will show up as problems
5765 with Internet Explorer 4.0 reading a page, but other browsers
5766 having no problem.) [Dean Gaudet]
5768 *) Create LARGE_WRITE_THRESHOLD define which determines how many
5769 bytes have to be supplied to bwrite() before it will consider
5770 doing a writev() to assemble multiple buffers in one system
5771 call. This is critical for modules such as mod_include,
5772 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
5773 strings in some cases. The result would be extra effort
5774 setting up writev(), and in many cases extra effort building
5775 chunks. The default is 31, it can be overriden at compile

5833 *) WIN32: mod_status display header didn't match fields. [Ben Laurie]
5835 *) The pthread_mutex_* functions return an error code, and don't
5836 set errno. [Igor Tatarinov <tatarino@prairie.NoDak.edu>]
5838 *) WIN32: Allow spaces to prefix the interpreter in #! lines.

5841 *) WIN32: Cure file leak in CGIs. [Peter Tillemans <pti@net4all.be>] PR#1523
5843 *) proxy_ftp: the directory listings generated by the proxy ftp module
5844 now have a title in which the path components are clickable and allow
5845 quick navigation to the clicked-on directory on the currently listed
5846 ftp server. This also fixes a bug where the ".." directory links would
5847 sometimes refer to the wrong directory. [Martin Kraemer]
5849 *) WIN32: Allocate the correct amount of memory for the scoreboard.

5862 *) WIN32: Work around brain-damaged spawn calls that can't deal
5863 with spaces and slashes. [Ben Laurie]
5865 *) WIN32: Fix the code so CGIs can use socket calls on Windows.
5866 The problem was that certain undocumented environment variables
5867 needed for sockets to work under Win32 were not being passed.
5868 [Frank Faubert <frank@sane.com>]
5870 *) Add a "-V" command line flag to the httpd binary. This
5871 flag shows some of the defines that Apache was compiled with.
5872 It is useful for debugging purposes. [Martin Kraemer]
5874 *) Start separating the ap_*() routines into their own library, so they
5875 can be used by items in src/support among other things.

5885 This turns out to be a bug in Winsock - select() doesn't always

5888 *) Directives owned by http_core can now use the new check_cmd_context()
5889 routine to ensure that they're not being used within a container
5890 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
5892 *) PORT: Recent changes made it necessary to add explicit prototype
5893 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
5895 *) It was necessary to distinguish between resources which are
5896 allocated in the parent, for cleanup in the parent, and resources
5897 which are allocated in each child, for cleanup in each child.
5898 A new pool was created which is passed to the module child_init
5899 and child_exit functions; modules are free to register per-child
5900 cleanups there. This fixes a bug with reliable piped logs.
5903 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
5904 unless it was also doing FancyIndexes, but it displayed the
5905 HeaderName file at the top under all circumstances. It now shows
5906 the ReadmeName file for simple indices, too, as it should.
5909 *) http_core was mmap()ing even in cases where it wasn't going to
5910 read the file. [Ben Hyde <bhyde@gensym.com>]
5912 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
5913 Now the rewriting engine (the heart of mod_rewrite) is organized more
5914 straight-forward, first time well documented and reduced to the really
5915 essential parts. All redundant cases were stripped off and processing now
5916 is the same for both per-server and per-directory context with only a
5917 minimum difference (the prefix stripping in per-dir context). As a
5918 side-effect some subtle restrictions and two recently discovered problems
5919 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
5920 context and restrictions on the substitution URL on redirects.
5921 Additionally some minor source cleanups were done.

6073 name of the virtual host (listed first in the log records by "%v").
6076 Changes with Apache 1.3b2 (there is no 1.3b1)
6078 *) TestCompile was not passing $LIBS [Dean Gaudet]
6080 *) Makefile.tmpl was not using $CFLAGS in the link phase.
6083 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
6084 rudimentary memory debugger which can be used on live servers with
6085 low impact -- it sets all allocated and freed memory bytes to 0xa5.
6086 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
6087 and free() for each object. This is far more expensive and should
6088 only be used for testing with tools such as Electric Fence and
6089 Purify. See main/alloc.c for more details. [Dean Gaudet]
6091 *) Configure uses a sh trap and didn't set its exitcode properly.
6092 [Dean Gaudet] PR#1159
6094 *) Yet another vhost revamp. Add the NameVirtualHost directive which
6095 explicitly lists the ip:port pairs that are to be used for name-vhosts.
6096 From a given ip:port, regardless what the Host: header is, you can
6097 only reach the vhosts defined on that ip:port. The precedence of
6098 vhosts was reversed to match other precedences in the config --
6099 the earlier vhosts override the later vhosts. All vhost matching was
6100 moved into http_vhost.[ch]. [Dean Gaudet]
6102 *) ap_inline can be used to force inlining. GNUC __attribute__() can
6103 be used for whatever reason is appropriate (i.e. format() warnings
6104 for printf style functions). Both are enabled only with
6105 gcc >= 2.7.x (so that we have fewer support issues with older
6106 versions). [Dean Gaudet]
6108 *) Fix support for Proxy Authentication (we were testing the response
6109 status too early). [Marc Slemko]
6111 *) CoreDumpDirectory directive directs where the core file is
6112 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
6113 received. [Marc Slemko, Dean Gaudet]
6115 *) PORT: Support for Atari MINT.
6116 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
6118 *) When booting, apache will now detach itself from stdin, stdout,
6119 and stderr. stderr will not be detached until after the config
6120 files have been read so you will be able to see initial error
6121 messages. After that all errors are logged in the error_log.
6122 This makes it more convenient to start apache via rsh, ssh,
6123 or crontabs. [Dean Gaudet] PR#523
6125 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
6126 Also removed the auto-generated link to www.apache.org that was the
6127 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
6129 *) send_fb would not detect aborted connections in some situations.
6132 *) mod_include would use uninitialized data when parsing certain
6133 expressions involving && and ||. [Brian Slesinsky] PR#1139
6135 *) mod_imap should only handle GET methods. [Jay Bloodworth]
6137 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
6139 *) mod_autoindex improperly counted &escapes; as more than one
6140 character in the description. It also improperly truncated
6141 descriptions that were exactly the maximum length.
6144 *) RedirectMatch was not properly escaping the result (PR#1155). Also
6145 "RedirectMatch /advertiser/(.*) $1" is now permitted.
6148 *) mod_include now uses symbolic names to check for request success
6149 and return HTTP errors, and correctly handles all types of
6150 redirections (previously it only did temporary redirect correctly).
6151 [Ken Coar, Roy Fielding]
6153 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
6154 r->filename. Since those two are meant to be in sync with each other
6155 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
6157 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
6158 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]
6160 *) Inetd mode (which is buggy) uses timeouts without having setup the
6161 jmpbuffer. [Dean Gaudet] PR#1064

6164 reporting a select error over and over.
6165 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
6167 *) Fixed error in proxy_util.c when looping through multiple host IP
6168 addresses. [Lars Eilebrecht] PR#974
6170 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
6171 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
6172 bytes before writing, but it will never split a log entry across a
6173 buffer boundary. [Dean Gaudet]
6175 *) API: the short_score record has been split into two pieces, one which
6176 the parent writes on, and one which the child writes on. As part of
6177 this change the get_scoreboard_info() function was removed, and
6178 scoreboard_image was exported. This change fixes a race condition
6179 in file based scoreboard systems, and speeds up changes involving the
6180 scoreboard in earlier 1.3 development. [Dean Gaudet]
6182 *) API: New register_other_child() API (see http_main.h) which allows
6183 modules to register children with the parent for maintenance. It
6184 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
6186 *) API: New piped_log API (see http_log.h) which implements piped logs,
6187 and will use register_other_child to implement reliable piped logs
6188 when it is available. The reliable piped logs part can be disabled
6189 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
6190 logs is only available on Unix. [Dean Gaudet]
6192 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
6193 meets_conditions(). This allows conditional HTTP selection to be
6194 handled separately from the storing of the header fields, and provides
6195 the ability for CGIs to set their own ETags for conditional checking.
6196 [Ken Coar, Roy Fielding] PR#895
6198 *) Changes to mod_log_config to allow naming of format strings.
6199 Format nicknames are defined with "LogFormat fmt nickname", and can
6200 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
6203 *) New module, "mod_speling", which can help find files even when
6204 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
6206 *) API: New function child_terminate() triggers the child process to
6207 exit, while allowing the child finish what it needs to for the
6208 current request first.
6209 [Doug MacEachern, Alexei Kosut]
6211 *) Windows now defaults to using full status reports with mod_status.
6212 [Alexei Kosut] PR #1094
6214 *) *Really* disable all mod_rewrite operations if the engine is off.
6215 Some things (like RewriteMaps) were checked/performed even if they
6216 weren't supposed to be. [Ken Coar] PR #991
6218 *) Implement a new timer scheme which eliminates the need to call alarm() all
6219 the time. Instead a counter in the scoreboard for each child is used to
6220 show when the child has made forward progress. The parent samples this
6221 counter every scoreboard maintenance cycle, and issues SIGALRM if no
6222 progress has been made in the timeout period. This reduces the static
6223 request best-case syscall count to 22 from 29. This scheme is only
6224 used by systems with memory-based scoreboards. [Dean Gaudet]
6226 *) The proxy now properly handles CONNECT requests which are sent
6227 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
6229 *) A script called apachectl has been added to the support
6230 directory. This script allows you to do things such as
6231 "apachectl start" and "apachectl restart" from the command
6234 *) Modules and core routines are now put into libraries, which
6235 simplifies the link line tremendously (among other advantages).
6238 *) Some of the MD5 names defined in Apache have been renamed to have
6239 an `ap_' prefix to avoid conflicts with routines supplied by
6240 external libraries. [Ken Coar]
6242 *) Removal of mod_auth_msql.c from the distribution. There are many
6243 other options for databases today. Rather than offer one option,
6244 offer none at this time. mod_auth_msql and other SQL database
6245 authentication modules can be found at the Apache Module Registry.
6246 http://modules.apache.org/ It would be nice to offer a generic
6247 mod_auth_sql option in the near future.
6249 *) PORT: BeOS support added [Alexei Kosut]
6251 *) Configure no longer accepts the -make option, since it creates
6252 Makefile on the fly based on Makefile.tmpl and Configuration.
6254 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
6255 of forcibly killing off all its processes and exiting without
6256 cleaning up. [Alexei Kosut]
6258 *) API: A new field in the request_rec, r->mtime, has been added to
6259 avoid gratuitous parsing of date strings. It is intended to hold
6260 the last-modified date of the resource (if applicable). An
6261 update_mtime() routine has also been added to advance it if
6262 appropriate. [Roy Fielding, Ken Coar]
6264 *) SECURITY: If a htaccess file can not be read due to bad permissions,
6265 deny access to the directory with a HTTP_FORBIDDEN. The previous
6266 behavior was to ignore the htaccess file if it could not be read.
6267 This change may make some setups with unreadable htaccess files
6268 stop working. [Marc Slemko] PR#817
6270 *) Add aplog_error() providing a mechanism to define levels of
6271 verbosity to the server error logging. This addition also provides
6272 the ability to log errors using syslogd. Error logging is configurable
6273 on a per-server basis using the LogLevel directive. Conversion
6274 of log_*() in progress. [Randy Terbush]
6276 *) Further enhance aplog_error() to not log filename, line number, and
6277 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
6279 *) WIN32: Canonicalise filenames under Win32. Short filenames are
6280 converted to long ones. Backslashes are converted to forward
6281 slashes. Case is converted to lower. Parts of URLs that do not
6282 correspond to files are left completely alone. [Ben Laurie]
6284 *) PORT: 2 new OSs added to the list of ports:
6285 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
6286 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
6288 *) Add the server version (SERVER_VERSION macro) to the "server
6289 configured and running" entry in the error_log. Also build an
6290 object file at link-time that contains the current time
6291 (SERVER_BUILT global const char[]), and include that in the
6294 *) Set r->headers_out when sending responses from the proxy.
6295 This fixes things such as the logging of headers sent from
6296 the proxy. [Marc Slemko] PR#659
6298 *) support/httpd_monitor is no longer distributed because the
6299 scoreboard should not be file based if at all possible. Use
6300 mod_status to see current server snapshot.
6302 *) (set_file_slot): New function, allowing auth directives to be
6303 independent of the server root, so the server documents can be
6304 moved to a different directory or machine more easily.
6305 [David J. MacKenzie]
6307 *) If no TransferLog is given explicitly, decline
6308 to log. This supports coexistence with other logging modules,
6309 such as the custom one that UUNET uses. [David J. MacKenzie]
6311 *) Check for titles in server-parsed HTML files.
6312 Ignore leading newlines and returns in titles. The old behavior
6313 of replacing a newline after <title> with a space causes the
6314 title to be misaligned in the listing. [David J. MacKenzie]
6316 *) Change mod_cern_meta to be configurable on a per-directory basis.
6317 [David J. MacKenzie]
6319 *) Add 'Include' directive to allow inclusion of configuration
6320 files within configuration files. [Randy Terbush]
6322 *) Proxy errors on connect() are logged to the error_log (nothing
6323 new); now they include the IP address and port that failed
6324 (*that's* new). [Ken Coar, Marc Slemko] PR#352
6326 *) Various architectures now define USE_MMAP_FILES which causes
6327 the server to use mmap() for static files. There are two
6328 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
6329 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
6330 number of bytes written in one cycle from a single mmap()d object,
6331 default 32768). [Dean Gaudet]
6333 *) API: Added post_read_request API phase which is run right after reading
6334 the request from a client, or right after an internal redirect. It is
6335 useful for modules setting environment variables that depend only on
6336 the headers/contents of the request. It does not run during subrequests
6337 because subrequests inherit pretty much everything from the main
6338 request. [Dean Gaudet]
6340 *) Added mod_unique_id which is used to generate a unique identifier for
6341 each hit, available in the environment variable UNIQUE_ID.
6344 *) init_modules is now called after the error logs have been opened. This
6345 allows modules to emit information messages into the error logs.
6348 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
6349 information for case where proxy module is not available. [Marc Slemko]
6351 *) PORT: Apache has need for mutexes to serialize its children around
6352 accept. In prior versions either fcntl file locking or flock file
6353 locking were used. The method is chosen by the definition of
6354 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
6355 and FLOCK for flock(). New options have been added:
6356 - SYSVSEM to use System V style semaphores
6357 - PTHREAD to use POSIX threads (appears to work on Solaris only)
6358 - USLOCK to use IRIX uslock
6359 Based on timing various techniques, the following changes were made
6361 - Linux 2.x uses flock instead of fcntl
6362 - Solaris 2.x uses pthreads
6363 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
6364 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
6365 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
6366 Martijn Koster <m.koster@pobox.com>]
6368 *) PORT: The semantics of accept/select make it very desirable to use
6369 mutexes to serialize accept when multiple Listens are in use. But
6370 in the case where only a single socket is open it is sometimes
6371 redundant to serialize accept(). Not all unixes do a good job with
6372 potentially dozens of children blocked on accept() on the same
6373 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
6374 the server will avoid serialization when listening on only one socket,
6375 and use serialization when listening on multiple sockets.
6376 [Dean Gaudet] PR#467
6378 *) Configure changes: TestLib replaced by TestCompile, which has
6379 some additional capability (such as doing a sanity check of
6380 the compiler and flags selected); the version of Solaris is now
6381 available via the #define value of SOLARIS2; IRIX n32bit libs
6382 now supported and selectable by new Configuration Rule: IRIXN32;
6383 We no longer default to -O2 optimization. [Jim Jagielski]
6385 *) Updated Configure: Configuration now uses AddModule to specify
6386 module source or binary file location, relative to src directory.
6387 Modules can be dropped into modules/extra, or in their own
6388 directory, and modules can come with a Makefile or Configure can
6389 create one. Modules can add compiler or library information to
6390 generated Makefiles. [Paul Sutton]
6392 *) Source core re-organisation: distributed modules are now in
6393 modules/standard. All other source code is in main. OS-specific
6394 code is in os/{unix,emx,win32} directories. [Paul Sutton]
6396 *) mod_browser has been removed, since it's replaced by mod_setenvif.
6399 *) Fix another long-standing bug in sub_req_lookup_file where it would
6400 happily skip past access checks on subdirectories looked up with
6401 relative paths. (It's used by mod_dir, mod_negotiation,
6402 and mod_include.) [Dean Gaudet]
6404 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
6405 N is the number of <Directory> sections, and M is the number of
6406 components in the filename of an object.
6408 To achieve this optimization the following config changes were made:
6409 - Wildcards (* and ?, not the regex forms) in <Directory>s,
6410 <Files>s, and <Location>s now treat a slash as a special
6411 character. For example "/home/*/public_html" previously would
6412 match "/home/a/andrew/public_html", now it only matches things
6413 like "/home/bob/public_html". This mimics /bin/sh behaviour.
6414 - It's possible now to use [] wildcarding in <Directory>, <Files>
6416 - Regex <Directory>s are applied after all non-regex <Directory>s.
6420 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
6421 and corrupted paths. [Dean Gaudet]
6423 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
6424 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
6425 be accessed now via backreferences $1..$9 in RewriteConds test-against
6426 strings in addition to RewriteRules subst string. Second the grouped
6427 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
6428 via backreferences %1..%9 both in following RewriteCond test-against
6429 strings and RewriteRules subst string. This provides maximum flexibility
6430 through the use of backreferences.
6431 Additionally the rewriting engine was cleaned up by putting common
6432 code to the new expand_backrefs_inbuffer() function.
6433 [Ralf S. Engelschall]
6435 *) When merging the main server's <Directory> and <Location> sections into
6436 a vhost, put the main server's first and the vhost's second. Otherwise
6437 the vhost can't override the main server. [Dean Gaudet] PR#717
6439 *) The <Directory> code would merge and re-merge the same section after
6440 a match was found, possibly causing problems with some modules.
6443 *) ip-based vhosts are stored and queried using a hashing function, which
6444 has been shown to improve performance on servers with many ip-vhosts.
6445 Some other changes had to be made to accommodate this:
6446 - the * address for vhosts now behaves like _default_
6447 - the matching process now is:
6448 - match an ip-vhost directly via hash (possibly matches main
6450 - if that fails, just pretend it matched the main server
6451 - if so far only the main server has been matched, perform
6452 name-based lookups (ServerName, ServerAlias, ServerPath)
6453 *only on name-based vhosts*
6454 - if they fail, look for _default_ vhosts
6455 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
6457 *) dbmmanage overhaul:
6458 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
6459 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
6460 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
6461 - provide better seed for rand
6462 - prompt for password as per getpass(3) (turn off echo, read from
6464 - use "newstyle" crypt based on $Config{osname} ($^O)
6465 - will not add a user if already in database, use new `update' command
6467 - added `check' command to check a users' password
6468 - added `import' command to convert existing password text-files or
6469 dbm files exported with `view'
6470 - more descriptive usage, general cleanup, 'use strict' clean, etc.
6473 *) Added psocket() which is a pool form of socket(), various places within
6474 the proxy weren't properly blocking alarms while registering the cleanup
6475 for its sockets. bclose() now uses pclose() and pclosesocket(). There
6476 was a bug where the client socket was being close()d twice due a still
6477 registered cleanup. [Dean Gaudet]
6479 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
6482 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
6483 [Jason Venner <jason@idiom.com>] PR#667
6485 *) Enable ``=""'' for RewriteCond directives to match against
6486 the empty string. This is the preferred way instead of ``^$''.
6487 [Ralf S. Engelschall]
6489 *) Fixed an infinite loop in mod_imap for references above the server root
6490 [Dean Gaudet] PR#748
6492 *) mod_proxy now has a ReceiveBufferSize directive, similar to
6493 SendBufferSize, so that the TCP window can be set appropriately
6494 for LFNs. [Phillip A. Prindeville]
6496 *) mod_browser has been replaced by the more general mod_setenvif
6497 (courtesy of Paul Sutton). BrowserMatch* directives are still
6498 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
6499 UnSetEnvIfZero directives. [Ken Coar]
6501 *) "HostnameLookups double" forces double-reverse DNS to succeed in
6502 order for remote_host to be set (for logging, or for the env var
6503 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
6506 *) mod_access overhaul:
6507 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
6508 and cidr syntax (i.e. 10.1.0.0/16). PR#762
6509 - Critical path was sped up by pre-computing a few things at config time.
6510 - The undocumented syntax "allow user-agents" was removed,
6511 the replacement is "allow from env=foobar" combined with mod_browser.
6512 - When used with hostnames it now forces a double-reverse lookup
6513 no matter what the directory settings are. This double-reverse
6514 doesn't affect any of the other routines that use the remote
6515 hostname. In particular it's still passed to CGIs and the log
6516 without the double-reverse check. Related PR#860.
6519 *) When a large bwrite() occurs (larger than the internal buffer size),
6520 while there is already something in the buffer, apache will combine
6521 the large write and the buffer into a single writev(). (This is
6522 in anticipation of using mmap() for reading files.)
6525 *) In obscure cases where a partial socket write occurred while chunking,
6526 Apache would omit the chunk header/footer on the next block. Cleaned
6527 up other bugs/inconsistencies in error conditions in buff.c. Fixed
6528 a bug where a long pause in DNS lookups could cause the last packet
6529 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
6531 *) API: Added child_exit function to module structure. This is called
6532 once per "heavy-weight process" just before a server child exit()'s
6533 e.g. when max_requests_per_child is reached, etc.
6534 [Doug MacEachern, Dean Gaudet]
6536 *) mod_include cleanup showed that handle_else was being used to handle
6537 endif. It didn't cause problems, but it was cleaned up too.
6540 *) mod_cern_meta would attempt to find meta files for the directory itself
6541 in some cases, but not in others. It now avoids it in all cases.
6544 *) mod_mime_magic would core dump if there was a decompression error.
6545 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
6547 *) PORT: some variants of DGUX require -lsocket -lnsl
6548 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
6550 *) mod_autoindex now allows sorting of FancyIndexed directory listings
6551 by the various fields (name, size, et cetera), either in ascending
6552 or descending order. Just click on the column header. [Ken Coar]
6554 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
6555 CPUs like the Alpha. Apache still stores ints in pointers, but that's
6556 the relatively safe direction. [Dean Gaudet] PR#344
6558 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
6559 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
6561 *) child_main avoids an unneeded call to select() when there is only one
6562 listening socket. [Dean Gaudet]
6564 *) In the event that the server is starved for idle servers it will
6565 spawn 1, then 2, then 4, ..., then 32 servers each second,
6566 doubling each second. It'll also give a warning in the errorlog
6567 since the most common reason for this is a poor StartServers
6568 setting. The define MAX_SPAWN_RATE can be used to raise/lower
6569 the maximum. [Dean Gaudet]
6571 *) Apache now provides an effectively unbuffered connection for
6572 CGI scripts. This means that data will be sent to the client
6573 as soon as the CGI pauses or stops output; previously, Apache would
6574 buffer the output up to a fixed buffer size before sending, which
6575 could result in the user viewing an empty page until the CGI finished
6576 or output a complete buffer. It is no longer necessary to use an
6577 "nph-" CGI to get unbuffered output. Given that most CGIs are written
6578 in a language that by default does buffering (e.g. perl) this
6579 shouldn't have a detrimental effect on performance.
6581 "nph-" CGIs, which formerly provided a direct socket to the client
6582 without any server post-processing, were not fully compatible with
6583 HTTP/1.1 or SSL support. As such they would have had to implement
6584 the transport details, such as encryption or chunking, in order
6585 to work properly in certain situations. Now, the only difference
6586 between nph and non-nph scripts is "non-parsed headers".
6587 [Dean Gaudet, Sameer Parekh, Roy Fielding]
6589 *) If a BUFF is switched from buffered to unbuffered reading the first
6590 bread() will return whatever remained in the buffer prior to the
6591 switch. [Dean Gaudet]
6593 Changes with Apache 1.3a1
6595 *) Added another Configure helper script: TestLib. It determines
6596 if a specified library exists. [Jim Jagielski]
6598 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
6599 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
6602 *) PORT: Some architectures use size_t for various lengths in network
6603 functions such as accept(), and getsockname(). The definition
6604 NET_SIZE_T is used to control this. [Dean Gaudet]
6606 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
6607 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
6608 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
6610 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
6611 [Igor N Kovalenko <infoh@mail.wplus.net>]
6613 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
6614 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
6615 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
6616 [Dean Gaudet] related PR#875
6618 *) API: Correct child_init() slot declaration from int to void, to
6619 match the init() declaration. Update mod_example to use the new
6622 *) added transport handle slot (t_handle) to the BUFF structure
6625 *) get_client_block() returns wrong length if policy is
6626 REQUEST_CHUNKED_DECHUNK.
6627 [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815
6629 *) Support the image map format of FrontPage. For example:

6634 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
6636 *) AddModuleInfo directive for mod_info which allows you to annotate
6637 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
6639 *) Added NoProxy directive to avoid using ProxyRemote for selected
6640 addresses. Added ProxyDomain directive to cause unqualified
6641 names to be qualified by redirection.
6642 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
6644 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
6645 header to the remote host in the proxy. [Sameer Parekh and
6648 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
6649 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
6650 URLs, fixed rewritelog(), fixed forced response code handling on
6651 redirects from within .htaccess files, disabled pipe locking under
6652 braindead SunOS 4.1.x, allow env variables to be set even on rules with
6653 no substitution, bugfixed situations where HostnameLookups is off, made
6654 mod_rewrite more thread-safe for NT port and fixed problem when creating
6655 an empty query string via "xxx?".
6656 This update also removes the copyright of Ralf S. Engelschall,
6657 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
6658 exclusively copyrighted by the Apache Group now. This happened because
6659 the author now has gifted mod_rewrite exclusively to the Apache Group and
6660 no longer maintains an external version.
6661 [Ralf S. Engelschall]
6663 *) API: Added child_init function to module structure. This is called
6664 once per "heavy-weight process" before any requests are handled.
6665 See http_config.h for more details. [Dean Gaudet]
6667 *) Anonymous_LogEmail was logging on each subrequest.
6668 [Dean Gaudet] PR#421, 868
6670 *) API: Added is_initial_req() which tests if the request being
6671 processed is the initial request, or a subrequest.
6674 *) Extended SSI (mod_include) now handles additional relops for
6675 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
6677 *) Configure fixed to correctly propagate user-selected options and
6678 settings (such as CC and OPTIM) to Makefiles other than
6679 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
6681 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
6682 directory indices to start with the contents of the HeaderName file
6683 if there is one. If there isn't one, the behaviour is unchanged.
6684 [Ken Coar, Roy Fielding, Andrey A. Chernov]
6686 *) WIN32: Modules can now be dynamically loaded DLLs using the
6687 LoadModule/LoadFile directives. Note that module DLLs must be
6688 compiled with the multithreaded DLL version of the runtime library.
6689 [Alexei Kosut and Ben Laurie]
6691 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
6692 This allows the admin to completely remove automatic indexing
6693 from the server, while still supporting the basic functions of
6694 trailing-slash redirects and DirectoryIndex files. Note that if
6695 you're carrying over an old Configuration file and you use directory
6696 indexing then you'll want to add:
6698 Module autoindex_module mod_autoindex.o
6700 before mod_dir in your Configuration. [Dean Gaudet]
6702 *) popendir/pclosedir created to properly protect directory scanning.
6703 [Dean Gaudet] PR#525
6705 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
6706 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
6707 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
6710 *) The AccessFileName directive can now take more than one filename.
6711 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
6713 *) The new mod_mime_magic can be used to "magically" determine the type
6714 of a file if the extension is unknown. Based on the unix file(1)
6715 command. [Ian Kluft <ikluft@cisco.com>]
6717 *) We now determine and display the time spent processing a
6718 request if desired. [Jim Jagielski]
6720 *) mod_status: PID field of "dead" child slots no longer displays
6721 main httpd process's PID. [Jim Jagielski]
6723 *) Makefile.nt added - to build all the bits from the command line:
6724 nmake -f Makefile.nt
6725 Doesn't yet work properly. [Ben Laurie]
6727 *) Default text of 404 error is now "Not Found" rather than the
6728 potentially misleading "File Not Found". [Ken Coar]
6730 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
6731 for the net if we require people that actually need this data to
6732 enable it. [Linus Torvalds]
6734 *) directory_walk() is an expensive function, keep a little more state to
6735 avoid needless string counting. Add two new functions make_dirstr_parent
6736 and make_dirstr_prefix which replace all existing uses of make_dirstr.
6737 The new functions are a little less general than make_dirstr, but
6738 work more efficiently (less memory, less string counting).
6741 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
6742 to LDFLAGS) to avoid complications with lex rules in make files.
6743 [Dean Gaudet] PR#372
6745 *) run_method optimized to avoid needless scanning over NULLs in the
6746 module list. [Dean Gaudet]
6748 *) Revamp of (unix) scoreboard management code such that it avoids
6749 unnecessary traversals of the scoreboard on each hit. This is
6750 particularly important for high volume sites with a large
6751 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
6752 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
6753 httpd.h. [Dean Gaudet]
6755 *) In configurations using multiple Listen statements it was possible for
6756 busy sockets to starve other sockets of service. [Dean Gaudet]
6758 *) Added hook so standalone_main can be replaced at compile time
6759 (define STANDALONE_MAIN)
6762 *) Lowest-level read/write functions in buff.c will be replaced with
6763 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
6764 compile time. The default sfio discipline will behave as apache
6765 would without sfio compiled in.
6768 *) Enhance UserDir directive (mod_userdir) to accept a list of
6769 usernames for the 'disable' keyword, and add 'enable user...' to
6770 selectively *en*able userdirs if they're globally disabled.
6773 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
6774 will work with Netscape dbm files. (dbmmanage will probably not
6775 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
6777 *) Add a ListenBacklog directive to control the backlog parameter
6778 passed to listen(). Also change the default to 511 from 512.
6781 *) API: A new handler response DONE which informs apache that the
6782 request has been handled and it can finish off quickly, similar to
6783 how it handles errors. [Rob Hartill]
6785 *) Turn off chunked encoding after sending terminating chunk/footer
6786 so that we can't do it twice by accident. [Roy Fielding]
6788 *) mod_expire also issues Cache-Control: max-age headers.
6791 *) API: Added kill_only_once option for free_proc_chain so that it won't
6792 aggressively try to kill off specific children. For fastcgi.
6793 [Stanley Gambarin <gambarin@OpenMarket.com>]
6795 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
6797 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
6798 When used together, these cause mod_dir to emit HEIGHT and WIDTH
6799 attributes in the FancyIndexing IMG tags. [Ken Coar]
6801 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
6803 *) PORT: Added Windows NT support
6804 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
6806 Changes with Apache 1.2.6
6808 *) mod_include when using XBitHack Full would send ETags in addition to
6809 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
6810 [Dean Gaudet] PR#1133
6812 *) SECURITY: When a client connects to a particular port/addr, and
6813 gives a Host: header ensure that the virtual host requested can
6814 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
6816 *) Support virtual hosts with wildcard port and/or multiple ports
6817 properly. [Ed Korthof <ed@organic.com>]
6819 *) Fixed some case-sensitivity issues according to RFC2068.
6822 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
6823 and mod_include.c. [Dean Gaudet]
6825 *) Variable 'cwd' was being used pointlessly before being set.
6828 *) SIGURG doesn't exist on all platforms.
6829 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
6831 *) When an error occurs during a POST, or other operation with a
6832 request body, the body has to be read from the net before allowing
6833 a keepalive session to continue. [Roy Fielding] PR#1399
6835 *) When an error occurs in fcntl() locking suggest the user look up
6836 the docs for LockFile. [Dean Gaudet]
6838 *) table_set() and table_unset() did not deal correctly with
6839 multiple occurrences of the same key. [Stephen Scheck
6840 <sscheck@infonex.net>, Ben Laurie] PR#1604
6842 *) send_fd_length() did not calculate total_bytes_sent properly in error
6843 cases. [Ben Reser <breser@regnow.com>] PR#1366
6845 *) r->connection->user was allocated in the wrong pool causing corruption
6846 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
6848 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
6849 Also removed the auto-generated link to www.apache.org that was the
6850 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
6852 *) Multiple "close" tokens may have been set in the "Connection"
6853 header, not an error, but a waste.
6854 [Ronald.Tschalaer@psi.ch] PR#1683
6856 *) "basic" and "digest" auth tokens should be tested case-insensitive.
6857 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
6859 *) It appears the "257th byte" bug (see
6860 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
6861 at the 256th byte as well. Fixed. [Dean Gaudet]
6863 *) mod_rewrite would not handle %3f properly in some situations.
6866 *) Apache could generate improperly chunked HTTP/1.1 responses when
6867 the bputc() or rputc() functions were used by modules (such as
6868 mod_include). [Dean Gaudet]
6870 *) #ifdef wrap a few #defines in httpd.h to make life easier on
6871 some ports. [Ralf Engelschall]
6873 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
6875 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
6877 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
6879 Changes with Apache 1.2.5
6881 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
6882 only an issue on systems without a MAXDNAME define or where
6883 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
6885 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
6888 *) Fix core dump in the ftp proxy when reading incorrectly formatted
6889 directory listings. [Marc Slemko]
6891 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
6894 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
6895 is used to read various types of files such as htaccess and
6896 htpasswd files. [Marc Slemko]
6898 *) SECURITY: Ensure that the buffer returned by ht_time is always
6899 properly null terminated. [Marc Slemko]
6901 *) SECURITY: General mod_include cleanup, including fixing several
6902 possible buffer overflows and a possible infinite loop. This cleanup
6903 was done against 1.3 code and then backported to 1.2, the result
6904 is a large difference (due to indentation cleanup in 1.3 code).
6905 Users interested in seeing a smaller set of relevant differences
6906 should consider comparing against src/modules/standard/mod_include.c
6907 from the 1.3b3 release. Non-indentation changes to mod_include
6908 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
6910 *) SECURITY: Numerous changes to mod_imap in a general cleanup
6911 including fixing a possible buffer overflow. This cleanup also
6912 was done with 1.3 code as a basis, see the the previous note
6913 about mod_include. [Dean Gaudet]
6915 *) SECURITY: If a htaccess file can not be read due to bad
6916 permissions, deny access to the directory with a HTTP_FORBIDDEN.
6917 The previous behavior was to ignore the htaccess file if it could not
6918 be read. This change may make some setups with unreadable
6919 htaccess files stop working. PR#817 [Marc Slemko]
6921 *) SECURITY: no2slash() was O(n^2) in the length of the input.
6922 Make it O(n). This inefficiency could be used to mount a denial
6923 of service attack against the Apache server. Thanks to
6924 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting

6931 [Jay Bloodworth <jay@pathways.sde.state.sc.us>]
6933 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
6935 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
6936 r->filename. Since those two are meant to be in sync with each other
6937 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
6939 *) mod_include did not properly handle all possible redirects from sub-
6940 requests. [Ken Coar]

6943 jmpbuffer. [Dean Gaudet] PR#1064

6946 reporting a select error over and over.
6947 [Rick Franchuk <rickf@transpect.net>] PR#1107
6949 Changes with Apache 1.2.4
6951 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
6952 always making requests with the full-URI instead of just the URI path.
6953 [Marc Slemko, Roy Fielding]
6955 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
6956 on this platform. [Marc Slemko]
6958 Changes with Apache 1.2.3
6960 *) The request to a remote proxy was mangled if it was generated as the
6961 result of a ProxyPass directive. URL schemes other than http:// were not
6962 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
6963 PR#812 [Lars Eilebrecht]
6965 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
6966 information for case where proxy module is not available. [Marc Slemko]
6968 *) Force proxy to always respond as HTTP/1.0, which it was failing to
6969 do for errors and cached responses. [Roy Fielding]
6971 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
6973 Changes with Apache 1.2.2 [not released]
6975 *) Fixed another long-standing bug in sub_req_lookup_file where it would
6976 happily skip past access checks on subdirectories looked up with relative
6977 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
6980 *) Add lockfile name to error message printed out when
6981 USE_FLOCK_SERIALIZED_ACCEPT is defined.
6984 *) Enhanced the chunking and error handling inside the buffer functions.
6985 [Dean Gaudet, Roy Fielding]
6987 *) When merging the main server's <Directory> and <Location> sections into
6988 a vhost, put the main server's first and the vhost's second. Otherwise
6989 the vhost can't override the main server. [Dean Gaudet] PR#717
6991 *) The <Directory> code would merge and re-merge the same section after
6992 a match was found, possibly causing problems with some modules.
6995 *) Fixed an infinite loop in mod_imap for references above the server root.
6996 [Dean Gaudet] PR#748
6998 *) mod_include cleanup showed that handle_else was being used to handle
6999 endif. It didn't cause problems, but it was cleaned up too.
7002 *) Last official synchronization of mod_rewrite with author version (because
7003 mod_rewrite is now directly developed by the author at the Apache Group):
7004 o added diff between mod_rewrite 3.0.6+ and 3.0.9
7005 minus WIN32/NT stuff, but plus copyright removement.
7007 - workaround for detecting infinite rewriting loops
7008 - fixed setting of env vars when "-" is used as subst string
7009 - fixed forced response code on redirects (PR#777)
7010 - fixed cases where r->args is ""
7011 - kludge to disable locking on pipes under braindead SunOS
7012 - fix for rewritelog in cases where remote hostname is unknown
7013 - fixed totally damaged request_rec walk-back loop
7014 o remove static from local data and add static to global ones.
7015 o replaced ugly proxy finding stuff by simple
7016 find_linked_module("mod_proxy") call.
7017 o added missing negation char on rewritelog()
7018 o fixed a few comment typos
7019 [Ralf S. Engelschall]
7021 *) Anonymous_LogEmail was logging on each subrequest.
7022 [Dean Gaudet] PR#421, PR#868
7024 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7025 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7026 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
7027 Additionally mod_browser now triggers during translate_name to workaround
7028 a deficiency in the header_parse phase.

7038 *) The proxy didn't treat the "Host:" keyword of the host header as case-
7039 insensitive. The proxy would corrupt the first line of a response from
7040 an HTTP/0.9 server. [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#813,814
7042 *) mod_include would log some bogus values occasionally.
7043 [Skip Montanaro <skip@calendar.com>, Marc Slemko] PR#797
7045 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
7046 under Solaris 2.x (up through 2.5.1). It has been fixed.
7047 [Dean Gaudet] PR#832
7049 *) API: In HTTP/1.1, whether or not a request message contains a body
7050 is independent of the request method and based solely on the presence
7051 of a Content-Length or Transfer-Encoding. Therefore, our default
7052 handlers need to be prepared to read a body even if they don't know
7053 what to do with it; otherwise, the body would be mistaken for the
7054 next request on a persistent connection. discard_request_body()
7055 has been added to take care of that. [Roy Fielding] PR#378
7057 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
7058 release version number, such that it always increases along the
7059 same lines as our source code branching. [Roy Fielding]
7061 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
7063 Changes with Apache 1.2.1
7065 *) SECURITY: Don't serve file system objects unless they are plain files,
7066 symlinks, or directories. This prevents local users from using pipes
7067 or named sockets to invoke programs for an extremely crude form of

7071 could contain "../" allowing a local user to "publish" any file on
7072 the system. No slashes are allowed now. [Dean Gaudet]
7074 *) SECURITY: It was possible to violate the symlink Options using mod_dir
7075 (headers, readmes, titles), mod_negotiation (type maps), or
7076 mod_cern_meta (meta files). [Dean Gaudet]
7078 *) SECURITY: Apache will refuse to run as "User root" unless
7079 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
7081 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
7082 if it contained a .htaccess disallowing symlinks. This is contrary
7083 to the rule that symlink permissions are tested with the symlink
7084 options of the parent directory. [Dean Gaudet] PR#353
7086 *) CONFIG: The LockFile directive can be used to place the serializing
7087 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
7088 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
7091 *) Request processing now retains state of whether or not the request
7092 body has been read, so that internal redirects and subrequests will
7093 not try to read it twice (and block). [Roy Fielding]
7095 *) Add a placeholder in modules/Makefile to avoid errors with certain
7096 makes. [Marc Slemko]
7098 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.
7099 [Dean Gaudet] PR#644
7101 *) mod_include was not properly changing the current directory.
7102 [Marc Slemko] PR#742
7104 *) Attempt to work around problems with third party libraries that do not
7105 handle high numbered descriptors (examples include bind, and
7106 solaris libc). On all systems apache attempts to keep all permanent
7107 descriptors above 15 (called the low slack line). Solaris users
7108 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
7109 which keeps all non-FILE * descriptors above 255. On all systems
7110 this should make supporting large numbers of vhosts with many open
7111 log files more feasible. If this causes trouble please report it,
7112 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
7113 [Dean Gaudet] various PRs
7115 *) Related to the last entry, network sockets are now opened before
7116 log files are opened. The only known case where this can cause
7117 problems is under Solaris with many virtualhosts and many Listen
7118 directives. But using -DHIGH_SLACK_LINE=256 described above will
7119 work around this problem. [Dean Gaudet]

7173 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
7174 reading from one buffer and writing to another, at least until it has
7175 a custom timeout handler. [Roy Fielding and Petr Lampa]
7177 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
7178 apparently due to a mismatch between sigaction and setjmp.

7185 *) Virtual hosts with the same ServerName, but on different ports, were
7186 not being selected properly. [Ed Korthof]

7191 [Chuck Murcko] PR#614
7193 *) If multiple requests on a single connection are used to retrieve
7194 data from different virtual hosts, the virtual host list would be
7195 scanned starting with the most recently used VH instead of the first,
7196 causing most virtual hosts to be ignored.

7206 has found matching variants, but none are acceptable, return the
7207 negotiation result if there are no more DirectoryIndex names to lookup.
7208 [Petr Lampa and Roy Fielding]
7210 *) If a soft_timeout occurs after keepalive is set, then the main child
7211 loop would try to read another request even though the connection
7212 has been aborted. [Roy Fielding]
7214 *) Configure changes: Allow for whitespace at the start of a
7215 Module declaration. Also, be more understanding about the
7216 CC=/OPTIM= format in Configuration. Finally, fix compiler
7217 flags if using HP-UX's cc compiler. [Jim Jagielski]
7219 *) Subrequests and internal redirects now inherit the_request from the
7220 original request-line. [Roy Fielding]
7222 *) Test for error conditions before creating output header fields, since
7223 we don't want the error message to include those fields. Likewise,
7224 reset the content_language(s) and content_encoding of the response
7225 before generating or redirecting to an error message, since the new
7226 message will have its own Content-* definitions. [Dean Gaudet]
7228 *) Restored the semantics of headers_out (headers sent only with 200..299
7229 and 304 responses) and err_headers_out (headers sent with all responses).
7230 Avoid the overhead of copying tables if err_headers_out is empty
7231 (the usual case). [Roy Fielding]

7234 not properly checking both the value configured by the DefaultType
7235 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
7236 of DEFAULT_TYPE to match the documented default (text/plain).

7242 *) Properly initialize the flock structures used by the mutex locking
7243 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
7246 *) The method for determining PATH_INFO has been restored to the pre-1.2b
7247 (and NCSA httpd) definition wherein it was the extra path info beyond
7248 the CGI script filename. The environment variable FILEPATH_INFO has
7249 been removed, and instead we supply the original REQUEST_URI to any
7250 script that wants to be Apache-specific and needs the real URI path.
7251 This solves a problem with existing scripts that use extra path info
7252 in the ScriptAlias directive to pass options to the CGI script.
7255 *) The _default_ change in 1.2b10 will change the behaviour on configs
7256 that use multiple Listen statements for listening on multiple ports.
7257 But that change is necessary to make _default_ consistent with other
7258 forms of <VirtualHost>. It requires such configs to be modified
7259 to use <VirtualHost _default_:*>. The documentation has been
7260 updated. [Dean Gaudet] PR#530
7262 *) If an ErrorDocument CGI script is used to respond to an error
7263 generated by another CGI script which has already read the message
7264 body of the request, the server would block trying to read the
7265 message body again. [Rob Hartill]

7268 other platforms). Fixed. [Ben Laurie] PR#512

7286 Changes with Apache 1.2b9 [never announced]
7288 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
7289 changes and in anticipation of 1.2 final release. [Roy Fielding]
7291 *) Fix problem with scripts not receiving a SIGPIPE when client drops
7292 the connection (e.g., when user presses Stop). Apache will now stop
7293 trying to send a message body immediately after an error from write.

7303 conditions in both forms of restart, and in SIGTERM. See
7304 htdocs/manual/stopping.html for details on stopping and
7305 restarting the parent. [Dean Gaudet]
7307 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
7308 memory allocator to avoid a behaviour that required extra blocks to
7309 be allocated. [Dean Gaudet]
7311 *) Allow suexec to access files relative to current directory but not

7339 *) If a soft timeout (or lingerout) occurs while trying to flush a

7341 then the timeout would be ignored. [Roy Fielding] PR#373
7343 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
7344 parsing of headers. If the terminating empty-line CRLF occurs starting
7345 at the 256th or 257th byte of output, then Navigator will think a normal
7346 image is invalid. We are guessing that this is because their initial
7347 read of a new request uses a 256 byte buffer. We check the bytes written
7348 so far and, if we are about to tickle the bug, we instead insert a
7349 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232

7352 of an external redirection. [Roy Fielding and Paul Sutton]

7409 *) The addition of <Location> and <File> directives made the
7410 sub_req_lookup_simple() function bogus, so we now handle
7411 the special cases directly. [Dean Gaudet]
7413 *) We now try to log where the server is dumping core when a fatal
7414 signal is received. [Ken Coar]
7416 *) Improved lingering_close by adding a special timeout, removing the
7417 spurious log messages, removing the nonblocking settings (they
7418 are not needed with the better timeout), and adding commentary
7419 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
7420 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
7422 *) Send error messages about setsockopt failures to the server error
7423 log instead of stderr. [Roy Fielding]
7425 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
7427 *) Stopgap solution for CGI 3-second delay with server-side includes: if
7428 processing a subrequest, allocate memory from r->main->pool instead
7429 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
7430 in the middle of an SSI request. [Dean Gaudet] PR #122
7432 *) Fixed status of response when POST is received for a nonexistent URL
7433 (was sending 405, now 404) and when any method is sent with a
7434 full-URI that doesn't match the server and the server is not acting
7435 as a proxy (was sending 501, now 403). [Roy Fielding]
7437 *) Host port changed to unsigned short. [Ken Coar] PR #276
7439 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
7441 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
7443 *) Report extra info from errno with many errors that cause httpd to exit.
7444 spawn_child, popenf, and pclosef now have valid errno returns in the
7445 event of an error. Correct problems where errno was stomped on
7446 before being reported. [Dean Gaudet]
7448 *) In the proxy, if the cache filesystem was full, garbage_coll() was
7449 never called, and thus the filesystem would remain full indefinitely.
7450 We now also remove incomplete cache files left if the origin server
7451 didn't send a Content-Length header and either the client has aborted
7452 transfer or bwrite() to client has failed. [Petr Lampa]
7454 *) Fixed the handling of module and script-added header fields.
7455 Improved the interface for sending header fields and reduced
7456 the duplication of code between sending okay responses and errors.
7457 We now always send both headers_out and err_headers_out, and
7458 ensure that the server-reserved fields are not being overridden,
7459 while not overriding those that are not reserved. [Roy Fielding]
7461 *) Moved transparent content negotiation fields to err_headers_out
7462 to reflect above changes. [Petr Lampa]
7464 *) Fixed the determination of whether or not we should make the
7465 connection persistent for all of the cases where some other part
7466 of the server has already indicated that we should not. Also
7467 improved the ordering of the test so that chunked encoding will
7468 be set whenever it is desired instead of only when KeepAlive
7469 is enabled. Added persistent connection capability for most error
7470 responses (those that do not indicate a bad input stream) when
7471 accessed by an HTTP/1.1 client. [Roy Fielding]
7473 *) Added missing timeouts for sending header fields, error responses,
7474 and the last chunk of chunked encoding, each of which could have
7475 resulted in a process being stuck in write forever. Using soft_timeout
7476 requires that the sender check for an aborted connection rather than
7477 continuing after an EINTR. Timeouts that used to be initiated before
7478 send_http_header (and never killed) are now initiated only within or
7479 around the routines that actually do the sending, and not allowed to
7480 propagate above the caller. [Roy Fielding]
7482 *) mod_auth_anon required an @ or a . in the email address, not both.
7485 *) per_dir_defaults weren't set correctly until directory_walk for
7486 name-based vhosts. This fixes an obscure bug with the wrong config
7487 info being used for vhosts that share the same ip as the server.
7490 *) Improved generation of modules/Makefile to be more generic for
7491 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
7493 *) Generate makefile dependency for Configuration based on the actual
7494 name given when running the Configure process. [Dean Gaudet]
7496 *) Fixed problem with vhost error log not being set prior to
7497 initializing virtual hosts. [Dean Gaudet]
7499 *) Fixed infinite loop when a trailing slash is included after a type map
7500 file URL (extra path info). [Petr Lampa]
7502 *) Fixed server status updating of per-connection counters. [Roy Fielding]
7504 *) Add documentation for DNS issues (reliability and security), and try
7505 to explain the virtual host matching process. [Dean Gaudet]
7507 *) Try to continue gracefully by disabling the vhost if a DNS lookup
7508 fails while parsing the configuration file. [Dean Gaudet]
7510 *) Improved calls to setsockopt. [Roy Fielding]
7512 *) Negotiation changes: Don't output empty content-type in variant list;
7513 Output charset in variant list; Return sooner from handle_multi() if
7514 no variants found; Add handling of '*' wildcard in Accept-Charset.
7515 [Petr Lampa and Paul Sutton]
7517 *) Fixed overlaying of request/sub-request notes and headers in
7518 mod_negotiation. [Dean Gaudet]
7520 *) If two variants' charset quality are equal and one is the default
7521 charset (iso-8859-1), then prefer the variant that was specifically
7522 listed in Accept-Charset instead of the default. [Petr Lampa]
7524 *) Memory allocation problem in push_array() -- it would corrupt memory
7525 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
7527 *) invoke_handler() doesn't handle mime arguments in content-type
7530 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
7533 *) Fixed problem with ErrorDocument not working for virtual hosts
7534 due to one of the performance changes in 1.2b7. [Dean Gaudet]
7536 *) Log an error message if we get a request header that is too long,
7537 since it may indicate a buffer overflow attack. [Marc Slemko]
7539 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
7540 not reject URLs without a double-slash, as per RFC2068 section 3.2.
7541 [Ken Coar] PR #146, #187
7543 *) Added table entry placeholder for new header_parser callback
7544 in all of the distributed modules. [Ken Coar] PR #191
7546 *) Allow for cgi files without the .EXE extension on them under OS/2.
7547 [Garey Smiley] PR #59
7549 *) Fixed error message when resource is not found and URL contains
7550 path info. [Petr Lampa and Dean Gaudet] PR #40
7552 *) Fixed user and server confusion over what should be a virtual host
7553 and what is the main server, resulting in access to something
7554 other than the name defined in the virtualhost directive (but
7555 with the same IP address) failing. [Dean Gaudet]
7557 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
7558 AIX; improves the redirection stuff to enable the users to generally
7559 redirect to http, https, gopher and ftp; added TIME variable for
7560 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
7561 special patterns >STRING, <STRING and =STRING to RewriteCond, which
7562 can be used in conjunction with %{TIME} or other variables to create
7563 time-dependent rewriting rules. [Ralf S. Engelschall]
7565 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
7566 Module authors may need to adjust their code for proper cleanup to take
7567 place (that is, call note_cleanups_for_fd()). This change fixes problems
7568 with file descriptors being erroneously closed when the proxy module was
7569 in use. [Ben Laurie]
7571 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
7572 initgroups() to hose the group information needed for later
7573 comparisons. [Randy Terbush]
7575 *) Remove unnecessary call to va_end() in create_argv() which
7576 caused a SEGV on some systems.
7578 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
7581 *) Clear memory allocated for listeners. [Randy Terbush]
7583 *) Improved handling of IP address as a virtualhost address and
7584 introduced "_default_" as a synonym for the default vhost config.
7585 [Dean Gaudet] PR #212
7587 Changes with Apache 1.2b7
7589 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
7591 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
7593 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
7594 - replace protocol response numbers with symbols
7595 - save variant-list into main request notes
7596 - free allocated memory from subrequests
7597 - merge notes, headers_out and err_headers_out
7599 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
7600 "HTTP/#.# ###*" to be more lenient about what we accept.
7603 *) more proxy FTP bug fixes:
7604 - Changed send_dir() to remove user/passwd from displayed URL.
7605 - Changed login error messages to be more descriptive.
7606 - remove setting of SO_DEBUG socket option
7607 - Make ftp_getrc() more lenient about multiline responses,
7608 specifically, 230 responses which don't have continuation 230-
7609 on each line). These seem to be all NT FTP servers, and while
7610 perhaps questionable, they appear to be legal by RFC 959.
7611 - Add missing kill_timeout() after transfer to user completes.
7614 *) Fixed problem where a busy server could hang when restarting
7615 after being sent a SIGHUP due to child processes not exiting.
7618 *) Modify mod_include escaping so a '\' only signifies an escaped
7619 character if the next character is one that needs
7620 escaping. [Ben Laurie]
7622 *) Eliminated possible infinite loop in mod_imap when relative URLs are
7623 used with a 'base' directive that does not have a '/' in it.
7624 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
7626 *) Reduced the default timeout from 1200 seconds to 300, and the
7627 one in the sample configfile from 400 to 300. [Marc Slemko]
7629 *) Stop vbprintf from crashing if given a NULL string pointer;
7630 print (null) instead. [Ken Coar]
7632 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
7633 [Marc Slemko and Roy Fielding]
7635 *) Fixed problem with mod_cgi-generated internal redirects trying to
7636 read the request message-body twice. [Archie Cobbs and Roy Fielding]
7638 *) Reduced timeout on lingering close, removed possibility of a blocked
7639 read causing the child to hang, and stopped logging of errors if
7640 the socket is not connected (reset by client). [Roy Fielding]
7642 *) Rearranged main child loop to remove duplication of code in
7643 select/accept and keep-alive requests, fixed several bugs regarding
7644 checking scoreboard_image for exit indication and failure to
7645 account for all success conditions and trap all error conditions,
7646 prevented multiple flushes before closing the socket; close the entire
7647 socket buffer instead of just one descriptor, prevent logging of
7648 EPROTO and ECONNABORTED on platforms where supported, and generally
7649 improved readability. [Roy Fielding]
7651 *) Extensive performance improvements. Cleaned up inefficient use of
7652 auto initializers, multiple is_matchexp calls on a static string,
7653 and excessive merging of response_code_strings. [Dean Gaudet]
7655 *) Added double-buffering to mod_include to improve performance on
7656 server-side includes. [Marc Slemko]
7658 *) Several fixes for suexec wrapper. [Randy Terbush]
7659 - Make wrapper work for files on NFS filesystem.
7660 - Fix portability problem of MAXPATHLEN.
7661 - Fix array overrun problem in clean_env().
7662 - Fix allocation of PATH environment variable
7664 *) Removed extraneous blank line is description of mod_status chars.
7667 *) Logging of errors from the call_exec routine simply went nowhere,
7668 since the logfile fd has been closed, so now we send them to stderr.
7669 [Harald T. Alvestrand]
7671 *) Fixed core dump when DocumentRoot is a CGI.
7672 [Ben Laurie, reported by geddis@tesserae.com]
7674 *) Fixed potential file descriptor leak in mod_asis; updated it and
7675 http_core to use pfopen/pfclose instead of fopen/fclose.
7676 [Randy Terbush and Roy Fielding]
7678 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
7679 as the DEC Alpha which is 64-bit but uses 32-bit ints.
7680 [Dean Gaudet and Ken Coar]
7682 *) Return a 302 response code to the client when sending a redirect
7683 due to a missing trailing '/' on a directory instead of a 301; now
7684 it is cacheable. [Markus Gyger]
7686 *) Fix condition where, if a bad directive occurs in .htaccess, and
7687 sub_request() goes first to this directory, then log_reason() will
7688 SIGSEGV because it doesn't have initialized r->per_dir_config.
7689 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
7691 *) Fix handling of lang_index in is_variant_better(). This was
7692 causing problems which resulted in the server sending the
7693 wrong language document in some cases. [Petr Lampa]
7695 *) Remove free() from clean_env() in suexec wrapper. This was nuking
7696 the clean environment on some systems.
7698 *) Tweak byteserving code (e.g. serving PDF files) to work around
7699 bugs in Netscape Navigator and Microsoft Internet Explorer.
7700 Emit Content-Length header when sending multipart/byteranges.
7703 *) Port to HI-UX/WE2. [Nick Maclaren]
7705 *) Port to HP MPE operating system for HP 3000 machines
7706 [Mark Bixby <markb@cccd.edu>]
7708 *) Fixed bug which caused a segmentation fault if only one argument
7709 given to RLimit* directives. [Ed Korthof]
7711 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
7713 *) Improved buffered output to the client by delaying the flush decision
7714 until the BUFF code is actually about to read the next request.
7715 This fixes a problem introduced in 1.2b5 with clients that send
7716 an extra CRLF after a POST request. Also improved chunked output
7717 performance by combining writes using writev() and removing as
7718 many bflush() calls as possible. NOTE: Platforms without writev()
7719 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
7720 or Configure, unless we have already done so. [Dean Gaudet]
7722 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
7724 *) Fixed mod_info output corruption bug introduced by buffer overflow
7725 fixes. [Dean Gaudet]
7727 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
7728 for the special case of a 304 response. [Paul Sutton]
7730 *) Improved handling of TRACE method by bypassing normal method handling
7731 and header parsing routines; fixed Allow response to always allow TRACE.
7734 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
7736 *) Cleaned-up some of the generated HTML. [Ken Coar]
7738 Changes with Apache 1.2b6
7740 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
7742 *) Fix typo introduced in fix for potential infinite loop around
7743 accept() in child_main(). This change caused the rev to 1.2b6.
7744 1.2b5 was never a public beta.
7746 Changes with Apache 1.2b5
7748 *) Change KeepAlive semantics (On|Off instead of a number), add
7749 MaxKeepAliveRequests directive. [Alexei Kosut]
7751 *) Various NeXT compilation patches, as well as a change in
7752 regex/regcomp.c since that file also used a NEXT define.
7755 *) Allow * to terminate the end of a directory match in mod_dir.
7756 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
7758 *) Don't call can_exec() if suexec_enabled. Calling this requires
7759 scripts executed by the suexec wrapper to be world executable, which
7760 defeats one of the advantages of running the wrapper. [Randy Terbush]
7762 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
7765 *) Migration from sprintf() to snprintf() to avoid buffer
7766 overflows. [Marc Slemko]
7768 *) Provide portable snprintf() implementation (ap_snprintf)
7769 as well as *cvt family. [Jim Jagielski]
7771 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
7774 *) Remove mod_fastcgi.c from the distribution. This module appears
7775 to be maintained more through the Open Market channels and should
7776 continue to be easily available at http://www.fastcgi.com/
7778 *) Fixed bug in modules/Makefile that wouldn't allow building in more
7779 than one subdirectory (or cleaning, either). [Jeremy Laidman]
7781 *) mod_info assumed that the config files were relative to ServerRoot.
7784 *) CGI scripts called as an error document resulting from failed
7785 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
7787 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
7790 *) Properly check errno to prevent display of a directory index
7791 when server receives a long enough URL to confuse stat().
7794 *) Several security enhancements to suexec wrapper. It is _highly_
7795 recommended that previously installed versions of the wrapper
7796 be replaced with this version. [Randy Terbush, Jason Dour]
7798 - ~user execution now properly restricted to ~user's home
7799 directory and below.
7800 - execution restricted to UID/GID > 100
7801 - restrict passed environment to known variables
7802 - call setgid() before initgroups() (portability fix)
7803 - remove use of setenv() (portability fix)
7805 *) Add HTTP/1.0 response forcing. [Ben Laurie]
7807 *) Add access control via environment variables. [Ben Laurie]
7809 *) Add rflush() function. [Alexei Kosut]
7811 *) remove duplicate pcalloc() call in new_connection().
7813 *) Fix incorrect comparison which could allow number of children =
7814 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
7815 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
7817 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
7818 AIX PS/2, CONVEXOS. [Jim Jagielski]
7820 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
7821 It's more portable. [Martin Kraemer]
7823 *) Replace references to make in Makefile.tmpl with $(MAKE).
7826 *) Add ProxyBlock directive w/IP address caching. Add IP address
7827 caching to NoCache directive as well. ProxyBlock works with all
7828 handlers; NoCache now also works with FTP for anonymous logins.
7829 Still more code cleanup. [Chuck Murcko]
7831 *) Add "header parse" API hook [Ben Laurie]
7833 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
7835 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
7837 *) Correctly allow access and auth directives in <Files> sections in
7838 server config files. [Alexei Kosut]
7840 *) Fix bug with ServerPath that could cause certain files to be not
7841 found by the server. [Alexei Kosut]
7843 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
7844 double-quote from text and so that it properly checks for unsupported
7845 status codes using the new index_of_response interface. [Roy Fielding]
7847 *) Multiple fixes to the lingering_close code in order to avoid being
7848 interrupted by a stray timeout, to avoid lingering on a connection
7849 that has already been aborted or never really existed, to ensure that
7850 we stop lingering as soon as any error condition is received, and to
7851 prevent being stuck indefinitely if the read blocks. Also improves
7852 reporting of error conditions. [Marc Slemko and Roy Fielding]
7854 *) Fixed initialization of parameter structure for sigaction.
7855 [mgyger@itr.ch, Adrian Filipi-Martin]
7857 *) Fixed reinitializing the parameters before each call to accept and
7858 select, and removed potential for infinite loop in accept.
7859 [Roy Fielding, after useful PR from adrian@virginia.edu]
7861 *) Fixed condition where, if a child fails to fork, the scoreboard would
7862 continue to say SERVER_STARTING forever. Eventually, the main process
7863 would refuse to start new children because count_idle_servers() will
7864 count those SERVER_STARTING entries and will always report that there
7865 are enough idle servers. [Phillip Vandry]
7867 *) Fixed bug in bcwrite regarding failure to account for partial writes.
7868 Avoided calling bflush() when the client is pipelining requests.
7869 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
7871 *) Added description of "." mode in server-status [Jim Jagielski]
7873 Changes with Apache 1.2b4
7875 *) Fix possible race condition in accept_mutex_init() that
7876 could leave a small security hole open allowing files to be
7877 overwritten in cases where the server UID has write permissions.
7880 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
7882 *) Fix portablity problem in util_script where ARG_MAX may not be
7883 defined for some systems.
7885 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
7888 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
7889 style magic #! token for better script portability. [Garey Smiley]
7891 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
7892 execution for ~userdir CGI. [Jason Dour]
7894 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
7896 *) Fix month off by one in suexec wrapper logging.
7898 Changes with Apache 1.2b3:
7900 *) Fix error in mod_cgi which could cause resources not to be properly
7901 freed, or worse. [Dean Gaudet]
7903 *) Fix find_string() NULL pointer dereference. [Howard Fear]
7905 *) Add set_flag_slot() at the request of Dirk and others.
7908 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
7910 *) Add changes to improve the error message given for invalid
7911 ServerName parameters. [Dirk vanGulik]
7913 *) Add "Authoritative" directive for Auth modules that don't
7914 currently have it. This gives admin control to assign authoritative
7915 control to an authentication scheme and allow "fall through" for
7916 those authentication modules that aren't "Authoritative" thereby
7917 allowing multiple authentication mechanisms to be chained.
7920 *) Remove requirement for ResourceConfig/AccessConfig if not using
7921 the three config file layout. [Randy Terbush]
7923 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
7925 *) Changes to suexec wrapper to fix the following problems:
7926 1. symlinked homedirs will kill ~userdirs.
7927 2. initgroups() on Linux 2.0.x clobbers gr->grid.
7928 3. CGI command lines paramters problems
7929 4. pw-pwdir for "docroot check" still the httpd user's pw record.
7930 [Randy Terbush, Jason Dour]
7932 *) Change create_argv() to accept variable arguments. This fixes
7933 a problem where arguments were not getting passed to the CGI via
7934 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
7936 *) Collapse multiple slashes in path URLs to properly apply
7937 handlers defined by <Location>. [Alexei Kosut]
7939 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
7941 *) Improve the accuracy of request duration timings by setting
7942 r->request_time in read_request_line() instead of read_request().
7945 *) Reset timeout while reading via get_client_block() in mod_cgi.c
7946 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
7948 *) Add the ability to pass different Makefile.tmpl files to Configure
7949 using the -make flag. [Rob Hartill]
7951 *) Fix coredump triggered when sending a SIGHUP to the server caused
7952 by an assertion failure, in turn caused by an uninitialised field in a
7956 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
7957 PATH_INFO from previous versions of Apache (in certain situations,
7958 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
7959 [later removed in 1.2b11]
7961 *) Add rwrite() function to API to allow for sending strings of
7962 arbitrary length. [Doug MacEachern]
7964 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
7966 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
7967 NeXT. [Jim Jagielski]
7969 *) Removed recent modification to promote the status code on internal
7970 redirects, since the correct fix was to change the default log format
7971 in mod_log_config so that it outputs the original status. [Rob Hartill]
7973 Changes with Apache 1.2b2:
7975 *) Update set_signals() to use sigaction() for setting handlers.
7976 This appears to fix a re-entrant problem in the seg_fault()
7977 bus_error() handlers. [Randy Terbush]
7979 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
7981 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
7983 *) proxy_http.c bugfixes: [Chuck Murcko]
7984 1) fixes possible NULL pointer reference w/NoCache
7985 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
7986 host would cache nothing if it was in the local domain,
7987 and the local domain was in the NoCache list)
7988 3) Adds Host: header when not available
7989 4) Some code cleanup and clarification
7991 *) mod_include.c bugfixes:
7992 1) Fixed an ommission that caused include variables to not
7993 be parsed in config errmsg directives [Howard Fear]
7994 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
7995 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
7996 4) Allow backslash-escaping to all quoted text
7997 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
7998 5) Pass variable to command line if not set in XSSI's env
8001 *) Fix infinite loop when processing Content-language lines in
8002 type-map files. [Alexei Kosut]
8004 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
8006 *) Fixed problem in set_[user|group] that prevented CGI execution
8007 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
8009 *) Added PORTING information file. [Jim Jagielski]
8011 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
8013 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
8015 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
8016 USE_FCNTL_SERIALIZED_ACCEPT was intended.
8018 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
8019 which caused problems of systems where socket s_addr is >32bits.
8021 *) Added comment to explain (r->chunked = 1) side-effect in
8022 http_protocol.c [Roy Fielding]
8024 *) Replaced use of index() in mod_expires.c with more appropriate
8025 and portable isdigit() test. [Ben Laurie]
8027 *) Updated Configure for ...
8028 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
8029 *-dg-dgux* (bad pattern match)
8030 QNX (DEF_WANTHSREGEX=yes)
8031 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
8034 and added some user diagnostic info. [Ben Laurie]
8036 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
8037 for better portability. [Jim Jagielski]
8039 *) Updated helpers/GuessOS for ...
8040 SCO 5 (recognize minor releases)
8041 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
8042 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
8043 IRIX64 (-sgi-irix64)
8044 ULTRIX (-unknown-ultrix)
8045 SINIX (-whatever-sysv4)
8046 NCR Unix (-ncr-sysv4)
8047 and fixed something in helpers/PrintPath [Ben Laurie]
8049 Changes with Apache 1.2b1
8051 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
8053 Changes with Apache 1.1.1
8055 *) Fixed bug where Cookie module would make two entries in the
8056 logfile for each access [Mark Cox]
8058 *) Fixed bug where Redirect in .htaccess files would cause memory
8059 leak. [Nathan Neulinger]
8061 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
8063 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
8065 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
8067 Changes with Apache 1.1.0
8069 *) Bring NeXT support up to date. [Takaaki Matsumoto]
8071 *) Bring QNX support up to date. [Ben Laurie]
8073 *) Make virtual hosts default to main server keepalive parameters.
8074 [Alexei Kosut, Ben Laurie]
8076 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
8078 *) Fix missing address family for connect, also remove unreachable statement
8079 in mod_proxy. [Ben Laurie]
8081 *) mod_env now turned on by default in Configuration.tmpl.
8083 *) Bugs which were fixed:
8084 a) yet more mod_proxy bugs [Ben Laurie]
8085 b) CGI works again with inetd [Alexei Kosut]
8086 c) Leading colons were stripped from passwords [osm@interguide.com]
8087 d) Another fix to multi-method Limit problem [jk@tools.de]
8089 Changes with Apache 1.1b4
8091 *) r->bytes_sent variable restored. [Robert Thau]
8093 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
8095 *) More possibly unsecure programs removed from the support directory.
8097 *) More mod_auth_msql authentication improvements.
8099 *) VirtualHosts based on Host: headers no longer conflict with the
8102 *) OS/2 compatibility enhancements. [Gary Smiley]
8104 *) POST now allowed to directory index CGI scripts.
8106 *) Actions now work with files of the default type.
8108 *) Bugs which were fixed:
8109 a) more mod_proxy bugs
8110 b) early termination of inetd requests
8111 c) compile warnings on several systems
8112 d) problems when scripts stop reading output early
8114 Changes with Apache 1.1b3
8116 *) Much of cgi-bin and all of cgi-src has been removed, due to
8117 various security holes found and that we could no longer support
8120 *) The "Set-Cookie" header is now special-cased to not merge multiple
8121 instances, since certain popular browsers can not handle multiple
8122 Set-Cookie instructions in a single header. [Paul Sutton]
8124 *) rprintf() added to buffer code, occurrences of sprintf removed.
8127 *) CONNECT method for proxy module, which means tunneling SSL should work.
8128 (No crypto needed) Also a NoCache config directive.
8130 *) Several API additions: pstrndup(), table_unset() and get_token()
8131 functions now available to modules.
8133 *) mod_imap fixups, in particular Location: headers are now complete
8136 *) New "info" module which reports on installed module set through a
8137 special URL, a la mod_status.
8139 *) "ServerPath" directive added - allows for graceful transition
8140 for Host:-header-based virtual hosts.
8142 *) Anonymous authentication module improvements.
8144 *) MSQL authentication module improvements.
8146 *) Status module design improved - output now table-based. [Ben Laurie]
8148 *) htdigest utility included for use with digest authentication
8151 *) mod_negotiation: Accept values with wildcards to be treated with
8152 less priority than those without wildcards at the same quality
8153 value. [Alexei Kosut]
8155 *) Bugs which were fixed:
8156 a) numerous mod_proxy bugs
8157 b) CGI early-termination bug [Ben Laurie]
8158 c) Keepalives not working with virtual hosts
8159 d) RefererIgnore problems
8160 e) closing fd's twice in mod_include (causing core dumps on
8161 Linux and elsewhere).
8163 Changes with Apache 1.1b2
8166 a) core dumps in mod_digest
8167 b) truncated hostnames/ip address in the logs
8168 c) relative URL's in mod_imap map files
8170 Changes with Apache 1.1b1
8172 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
8174 Changes with Apache 1.0.3
8176 *) Internal redirects which occur in mod_dir.c now preserve the
8177 query portion of a request (the bit after the question mark).
8180 *) Escape active characters '<', '>' and '&' in html output in
8181 directory listings, error messages and redirection links.
8184 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
8186 *) Fix for POSIX compliance in waiting for processes in alloc.c.
8189 *) setsockopt no longer takes a const declared argument [Martijn Koster]
8191 *) Reset timeout timer after each successful fwrite() to the network.
8192 This patch adds a reset_timeout() procedure that is called by
8193 send_fd() to reset the timeout ever time data is written to the net.
8196 *) timeout() signal handler now checks for SIGPIPE and reports
8197 lost connections in a more user friendly way. [Rob Hartill]
8199 *) Location of the "scoreboard" file which used to live in /tmp is
8200 now configurable (for OSes that can't use mmap) via ScoreBoardFile
8201 which works similar to PidFile (in httpd.conf) [Rob Hartill]
8203 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
8205 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
8206 which caused a SEGV with cookies enabled
8208 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
8211 *) Log the UNIX textual error returned by some system calls, in
8212 particular errors from accept() [David Robinson]
8214 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
8216 Changes with Apache 1.0.2
8218 *) patch to get Apache compiled on UnixWare 2.x, recommended as
8219 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
8221 *) Fix get_basic_auth_pw() to set the auth_type of the request.
8224 *) past changes to http_config.c to only use the
8225 setrlimit function on systems defining RLIMIT_NOFILE
8226 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
8227 for SUNOS and prototypes the needed functions.
8229 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
8232 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
8234 *) Merge multiple headers from CGI scripts instead of taking last
8235 one. [David Robinson]
8237 *) Add support for SCO 5. [Ben Laurie]
8239 Changes with Apache 1.0.1
8241 *) Silence mod_log_referer and mod_log_agent if not configured
8244 *) Recursive includes can occur if the client supplies PATH_INFO data
8245 and the server provider uses relative links; as file.html
8246 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
8248 *) The replacement for initgroups() did not call {set,end}grent(). This
8249 had two implications: if anything else used getgrent(), then
8250 initgroups() would fail, and it was consuming a file descriptor.
8253 *) On heavily loaded servers it was possible for the scoreboard to get
8254 out of sync with reality, as a result of a race condition.
8255 The observed symptoms are far more Apaches running than should
8256 be, and heavy system loads, generally followed by catastrophic
8257 system failure. [Ben Laurie]
8259 *) Fix typo in license. [David Robinson]
8261 Changes with Apache 1.0.0 23 Nov 1995
8263 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
8265 Changes with Apache 0.8.16 05 Nov 1995
8267 *) New man page for 'httpd' added to support directory [David Robinson]
8269 *) .htgroup files can have more than one line giving members for a
8270 given group (each must have the group name in front), for NCSA
8271 back-compatibility [Robert Thau]
8273 *) Mutual exclusion around accept() is on by default for SVR4 systems
8274 generally, since they generally can't handle multiple processes in
8275 accept() on the same socket. This should cure flaky behavior on
8276 a lot of those systems. [David Robinson]
8278 *) AddType, AddEncoding, and AddLanguage directives take multiple
8279 extensions on a single command line [David Robinson]
8281 *) UserDir can be disabled for a given virtual host by saying
8282 "UserDir disabled" in the <VirtualHost> section --- it was a bug
8283 that this didn't work. [David Robinson]
8285 *) Compiles on QNX [Ben Laurie]
8287 *) Corrected parsing of ctime time format [David Robinson]
8289 *) httpd does a perror() before exiting if it can't log its pid
8290 to the PidFile, to make diagnosing the error a bit easier.
8293 *) <!--#include file="..."--> can no longer include files in the
8294 parent directory, for NCSA back-compatibility. [David Robinson]
8296 *) '~' is *not* escaped in URIs generated for directory listings
8299 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
8301 *) Fixed bug involving handling URIs with escaped %-characters
8302 in redirects [David Robinson]
8304 Changes with Apache 0.8.15 14 Oct 1995
8306 *) Switched to new, simpler license
8308 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
8310 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
8312 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
8314 *) Correctly handles internal redirects to files with names containing '%'
8317 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
8319 *) Use geteuid() rather than getuid() to see if we have root privilege,
8320 so that server correctly resets privilege if run setuid root. [Andrew
8323 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
8326 *) Fix relative URLs in imagemap files [Randy Terbush]
8328 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
8331 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
8332 entries all name the same one. [David Robinson]
8334 *) Fix directory listings with filenames containing unusual characters
8337 *) Better URI-escaping for generated URIs in directories with filenames
8338 containing unusual characters [Ben Laurie]
8340 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
8342 *) Unblock alarms on error return from spawn_child() [David Robinson]
8344 *) Sample Config files have extra note for SCO users [Ben Laurie]
8346 *) Configuration has note for HP-UX users [Rob Hartill]
8348 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
8350 *) Nuked bogus #define in httpd.h [David Robinson]
8352 *) Better test for whether a system has setrlimit() [David Robinson]
8354 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
8356 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
8359 Changes with Apache 0.8.14 19 Sep 1995
8361 *) Compiles on SCO ODT 3.0 [Ben Laurie]
8363 *) AddDescription works (better) [Ben Laurie]
8365 *) Leaves an intelligible error diagnostic when it can't set group
8366 privileges on standalone startup [Andrew Wilson]
8368 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
8369 that machine, which claims to be BSD but does not support RLIMIT.
8372 *) gcc -Wall no longer complains about an unused variable when util.c
8373 is compiled with -DMINIMAL_DNS [Andrew Wilson]
8375 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
8377 Changes with Apache 0.8.13 07 Sep 1995
8379 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
8381 *) Have built-in imagemap code recognize & honor Point directive [James
8384 *) Generate cleaner directory listings in directories with a mix of
8385 long and short filenames [Rob Hartill]
8387 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
8389 *) Properly default ServerName for virtual servers [Robert Thau]
8391 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
8392 Paul Richards and a cast of thousands...]
8394 *) On self-identified BSD systems (we don't try to guess any more),
8395 allocate a few extra file descriptors per virtual host with setrlimit,
8396 if we can, to avoid running out. [Randy Terbush]
8398 *) Write 22-character lock file name into buffer with enough space
8399 on startup [Konstantin Olchanski]
8401 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
8404 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
8406 *) Suppress -Wall warning by initializing variable in negotiation code
8407 [Tobias Weingartner]
8409 Changes with Apache 0.8.12 31 Aug 1995
8411 *) Doesn't pause three seconds after including a CGI script which is
8412 too slow to die off (this is done by not even trying to kill off
8413 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
8414 after the entire document has been processed). [Robert Thau]
8416 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
8418 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
8420 *) Allows .htaccess files to override <Directory> sections naming the
8421 same directory [David Robinson]
8423 *) Removed an efficiency hack in sub_req_lookup_uri which was
8424 causing certain extremely marginal cases (e.g., ScriptAlias of a
8425 *particular* index.html file) to fail. [David Robinson]
8427 *) Doesn't log an error when the requested URI requires
8428 authentication, but no auth header line was supplied by the
8429 client; this is a normal condition (the client doesn't no auth is
8430 needed here yet). [Robert Thau]
8432 *) Behaves more sanely when the name server loses its mind [Sean Welch]
8434 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
8436 *) RFC931 code no longer passes out name of prior clients on current
8437 requests if the current request came from a server that doesn't
8438 do RFC931. [David Robinson]
8440 *) Configuration script accepts "Module" lines with trailing whitespace.
8443 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
8445 *) Cleaned up comments in mod_cgi.c [Robert Thau]
8447 Changes with Apache 0.8.11 24 Aug 1995
8449 *) Wildcard <Directory> specifications work. [Robert Thau]
8451 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
8453 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
8454 the file being requested itself, in addition to the directories leading
8455 up to it. [Robert Thau]
8457 *) Logs access failures due to symlink checks or invalid client address
8458 in the error log [Roy Fielding, Robert Thau]
8460 *) Symlink checks deal correctly with systems where lstat of
8461 "/path/to/some/link/" follows the link. [Thau, Fielding]
8463 *) Doesn't reset DirectoryIndex to 'index.html' when
8464 other directory options are set in a .htaccess file. [Robert Thau]
8466 *) Clarified init code and nuked bogus warning in mod_access.c
8469 *) Corrected several directives in sample srm.conf
8470 --- includes corrections to directory indexing icon-related directives
8471 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
8472 icons for encodings right, and turning on AddEncoding by default).
8475 *) Corrected descriptions of args to AddIcon and AddAlt in command table
8478 *) INSTALL & README mention "contributed modules" directory [Brian
8481 *) Fixed English in the license language... "for for" --> "for".
8484 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
8485 mod_alias.c, merging it almost completely with handling of Alias, and
8486 adding a 'notes' field to the request_rec which allows the CGI module
8487 to discover whether the Alias module has put this request through
8488 ScriptAlias (which it needs to know for back-compatibility, as the old
8489 NCSA code did not check Options ExecCGI in ScriptAlias directories).
8492 Changes with Apache 0.8.10 18 Aug 1995
8494 *) AllowOverride applies to the named directory, and not just
8495 subdirectories. [David Robinson]
8497 *) Do locking for accept() exclusion (on systems that need it)
8498 using a special file created for the purpose in /usr/tmp, and
8499 not the error log; using the error log causes real problems
8500 if it's NFS-mounted; this is known to be the cause of a whole
8501 lot of "server hang" problems with Solaris. [David Robinson;
8502 thanks to Merten Schumann for help diagnosing the problem].
8504 Changes with Apache 0.8.9 12 Aug 1995
8506 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
8508 *) Nested includes see environment variables of the including document,
8509 for NCSA bug-compatibility (some sites have standard footer includes
8510 which try to print out the last-modified date). [Eric Hagberg/Robert
8513 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
8514 URI as a CGI script, even if it would have been treated as something
8515 else if requested directly, for NCSA back-compatibility. (Note that
8516 this means that people who know the name of the script can see the
8517 code just by asking for it). [Robert Thau]
8519 *) New version of dbmmanage script included in support directory as
8522 *) Check if scoreboard file couldn't be opened, and say so, rather
8523 then going insane [David Robinson]
8525 *) POST to CGI works on A/UX [Jim Jagielski]
8527 *) AddIcon and AddAlt commands work properly [Rob Hartill]
8529 *) NCSA server push works properly --- the Arena bug compatibility
8530 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
8531 if you still want the workaround). [Rob Hartill]
8533 *) If client didn't submit any Accept-encodings, ignore encodings in
8534 content negotiation. (NB this will all have to be reworked anyway
8535 for the new HTTP draft). [Florent Guillaume]
8537 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
8539 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
8541 *) Give Redirect priority over Alias, for NCSA bug compatibility
8544 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
8545 paralleling earlier bug fix for CGI [David Robinson]
8547 *) If DBM auth is improperly configured, report a server error and don't
8550 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
8551 it seems to work well enough without it (even in a 10 hits/sec
8552 workout), and the overhead for the locking under A/UX is
8553 alarmingly high (though it is very low on other systems).
8554 [Eric Hagberg, Jim Jagielski]
8556 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
8558 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
8559 Behlendorf/Eric Hagberg]
8561 *) More improvements to default Configuration for A/UX [Jim Jagielski]
8563 *) Compiles clean on NEXT [Rob Hartill]
8565 *) Compiles clean on SGI [Robert Thau]
8567 Changes with Apache 0.8.8 08 Aug 1995
8569 *) SunOS library prototypes now never included unless explicitly
8570 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
8571 people using GNU libc on SunOS are screwed by prototypes for the
8574 (Those who wish to compile clean with gcc -Wall on a standard
8575 SunOS setup need the prototypes, and may obtain them using
8576 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
8577 with nonstandard libraries are presumably competent to make their
8580 *) Strips trailing '/' characters off both args to the Alias command,
8581 to make 'Alias /foo/ /bar/' work.
8583 Changes with Apache 0.8.7 03 Aug 1995
8585 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
8586 [reported by David Robinson]
8588 *) Compiles clean on OSF/1 [David Robinson]
8590 *) Added some of the more recent significant changes (AddLanguage stuff,
8591 experimental LogFormat support) to CHANGES file in distribution root
8594 Changes with Apache 0.8.6 02 Aug 1995
8596 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
8597 (If you actually wanted a conditional GET which bypassed the cache, you
8598 couldn't get it). [Reported by Roy Fielding]
8600 *) Properly terminate headers on '304 Not Modified' replies to conditional
8601 GETs --- no browser we can find cares much, but the CERN proxy chokes.
8602 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
8604 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
8606 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
8607 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
8608 and older versions don't set the __SUNPRO_C preprocessor variable). On
8609 all other systems, these are never used anyway. [Reported by Mark Cox].
8611 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
8613 Changes with Apache 0.8.5 01 Aug 1995
8615 *) Added last-minute configurable log experiment, as optional module
8617 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
8618 properly. (One-line fix to http_protocol.c).
8620 *) Work around bogus behavior when reloading from Netscape.
8621 It's Netscape's bug --- for some reason they expect a request with
8622 If-modified-since: to not function as a conditional GET if it also
8623 comes with Pragma: no-cache, which is way out of line with the HTTP
8624 spec (according to Roy Fielding, the redactor).
8626 *) Added parameter to set maximum number of server processes.
8628 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
8631 *) IdentityCheck bugfix [Chuck Murcko].
8633 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
8635 *) More sample config file corrections; add extension to AddType for
8636 *.asis, move AddType generic description to its proper place, and
8637 fix miscellaneous typos. [ Alexei Kosut ]
8639 *) Deleted the *other* reference to the regents from the Berkeley
8640 legal disclaimer (everyplace).
8642 *) Nuked Shambhala name from src/README; had already cleaned it out
8645 Changes with Apache 0.8.4
8647 *) Changes to server-pool management parms --- renamed current
8648 StartServers to MinSpareServers, created separate StartServers
8649 parameter which means what it says, and renamed MaxServers to
8650 MaxSpareServers (though the old name still works, for NCSA 1.4
8651 back-compatibility). The old names were generally regarded as
8652 too confusing. Also altered "docs" in sample config files.
8654 *) More improvements to default config files ---
8655 sample directives (commented out) for XBitHack, BindAddress,
8656 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
8657 defaults, AddTypes for send-as-is and imagemap magic types, and
8658 improvements to samples for DirectoryIndex [Alexei Kosut]
8660 *) Yet more improvements to default config files --- changes to
8661 Alexei's sample AddLanguage directives, and sample LanguagePriority
8662 [ Florent Guillaume ]
8664 *) Set config file locations properly if not set in httpd.conf
8667 *) Don't escape URIs in internal redirects multiple times; don't
8668 do that when translating PATH_INFO to PATH_TRANSLATED either.
8671 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
8673 Changes with Apache 0.8.3
8675 *) Edited distribution README to *briefly* summarize installation
8676 procedures, and give a pointer to the INSTALL file in the src/
8679 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
8680 recent NCSA distributions.
8682 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
8683 exist for the same directory, use both and don't segfault. [Reported
8686 *) Proper makefile dependencies [David Robinson]
8688 *) Note (re)starts in error log --- reported by Rob Hartill.
8690 *) Only call no2slash() after get_path_info() has been done, to
8691 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
8692 reported by Andrew Wilson, though this one is probably a real bug]
8694 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
8695 dump core when Referer is not supplied. [Randy Terbush]
8697 *) Lightly edited sample config files to refer people to our documentation
8698 instead of NCSA's, and to list Rob McCool as *original* author (also
8699 deleted his old, and no doubt non-functional email address). Would be
8700 nice to have examples of new features...
8702 Changes with Apache 0.8.2 19 Jul 1995
8704 *) Added AddLanuage code [Florent Guillaume]
8706 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
8708 *) All sorts of problems when MultiViews finds a directory. It would
8709 be nice if mod_dir.c was robust enough to handle that, but for now,
8710 just punt. [reported by Brian Behlendorf]
8712 *) Wait for all children on restart, to make sure that the old socket
8713 is gone and we can reopen it. [reported by Randy Terbush]
8715 *) Imagemap module is enabled in default Configuration
8717 *) RefererLog and UserAgentLog modules properly default the logfile
8720 *) Mark Cox's mod_cookies added to the distribution as an optional
8721 module (commented out in the default Configuration, and noted as
8722 an experiment, along with mod_dld). [Mark Cox]
8724 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
8726 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
8728 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
8730 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
8733 Changes with Apache 0.8.1
8735 *) New imagemap module [Randy Terbush]
8737 *) Replacement referer log module with NCSA-compatible RefererIgnore
8738 [Matthew Gray again]
8740 *) Don't mung directory listings with very long filenames.
8743 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
8745 *) New config script. See INSTALL for info. [Robert Thau]
8747 *) Scoreboard mechanism for regulating the number of extant server
8748 processes. MaxServers and StartServers defaults are the same as
8749 for NCSA, but the meanings are slightly different. (Actually,
8750 I should probably lower the MaxServers default to 10).
8752 Before asking for a new connection, each server process checks
8753 the number of other servers which are also waiting for a
8754 connection. If there are more than MaxServers, it quietly dies
8755 off. Conversely, every second, the root, or caretaker, process
8756 looks to see how many servers are waiting for a new connection;
8757 if there are fewer than StartServers, it starts a new one. This
8758 does not depend on the number of server processes already extant.
8759 The accounting is arranged through a "scoreboard" file, named
8760 /tmp/htstatus.*, on which each process has an independent file
8761 descriptor (they need to seek without interference).
8763 The end effect is that MaxServers is the maximum number of
8764 servers on an *inactive* server machine, but more will be forked
8765 off to handle unusually heavy loads (or unusually slow clients);
8766 these will die off when they are no longer needed --- without
8767 reverting to the overhead of full forking operation. There is a
8768 hard maximum of 150 server processes compiled in, largely to
8769 avoid forking out of control and dragging the machine down.
8770 (This is arguably too high).
8772 In my server endurance tests, this mechanism did not appear to
8773 impose any significant overhead, even after I forced it to put the
8774 scoreboard file on a normal filesystem (which might have more
8775 overhead than tmpfs). [Robert Thau]
8777 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
8780 *) Read .htaccess files even in directory with <Directory> section.
8781 (Former incompatibility noted on mailing list, now fixed). [Robert
8784 *) "HEAD /" gives the client a "Bad Request" error message, rather
8785 than trying to send no body *and* no headers. [Cliff Skolnick].
8787 *) Don't produce double error reports for some very obscure cases
8788 mainly involving auth configuration (the "all modules decline to
8789 handle" case which is a sure sign of a server bug in most cases,
8790 but also happens when authentication is badly misconfigured).
8793 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
8794 it's *for*, and this sort of thing really shouldn't be cluttering
8795 up the Makefile). [Robert Thau]
8797 *) Incidental code cleanups in http_main.c --- stop dragging
8798 sa_client around; just declare it where used. [Robert Thau]
8800 *) Another acc-related fix. (It doesn't like const char
8801 in some places...). [Mark Cox]
8803 Changes with Shambhala 0.6.1 13 Jul 1995
8805 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
8806 Also, fixed auth typo in http_protocol.c unmasked by this fix.
8808 *) Compiles clean with acc on SunOS [Paul Sutton]
8810 *) Reordered modules in modules.c so that Redirect takes priority
8811 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
8812 believe it or not, he has an actual site with a ScriptAlias and
8813 a Redirect declared for the *exact same directory*. Even *my*
8814 compatibility fetish wouldn't motivate me to fix this if the fix
8815 required any effort, but it doesn't, so what the hey.
8817 *) Fixed to properly default several server_rec fields for virtual
8818 servers from the corresponding fields in the main server_rec.
8819 [Cliff Skolnick --- 'port' was a particular irritant].
8821 *) No longer kills off nph- child processes before they are
8822 finished sending output. [Matthew Gray]
8824 Changes with Shambhala 0.6.0 10 Jul 1995
8826 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
8827 the connection to the client in an "aborted" state, but otherwise
8828 allow whatever handlers are running to clean up. hard_timeout()s
8829 abort the request in progress completely; anything not tied to some
8830 resource pool cleanup will leak. They're still around because I
8831 haven't yet come up with a more elegant way of handling
8832 timeouts when talking to something that isn't the client. The
8833 default_handler and the dir_handler now use soft timeouts, largely
8834 so I can test the feature. [Robert Thau]
8836 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
8837 the case of log handlers dying prematurely is probably handled VERY
8838 gracelessly at this point, and if the logger stops reading input,
8839 the server will hang. (It is known to correctly restart the
8840 logging process on server restart; this is (should be!) going through
8841 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
8842 script). [Robert Thau]
8844 *) asis files supported (new module). [Robert Thau]
8846 *) IdentityCheck code is compiled in, but has not been tested. (I
8847 don't know anyone who runs identd). [Robert Thau]
8849 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
8850 came in with the request, for NCSA bug-compatibility. [Robert Thau]
8852 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
8854 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
8855 as timeouts are not in scope. [Robert Thau]
8857 *) quoted-string args in config files now handled correctly (doesn't drop
8858 the last character). [Robert Thau; reported by Randy Terbush]
8860 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
8861 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
8863 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
8864 default default type); the former default default behavior when all
8865 type-checkers defaulted had been a core dump. [Paul Sutton]
8867 *) Copy filenames out of the struct dirent when indexing
8868 directories. (On Linux, readdir() returns a pointer to the same
8869 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
8871 Changes with Shambhala 0.5.3 [not released]
8873 *) Default response handler notes "file not found" in the error log,
8874 if the file was not found. [Cliff Skolnick].
8876 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
8877 code no longer sets up bogus PATH_INFO which fakes out the directory
8878 handler). [Cliff Skolnick]
8880 Changes with Shambhala 0.5.2 06 Jul 1995
8882 *) Changes to http_main.c --- root server no longer plays silly
8883 games with SIGCHLD, and so now detects and replaces dying
8884 children. Child processes just die on SIGTERM, without taking
8885 the whole process group with them. Potential problem --- if any
8886 child process refuses to die, we hang in restart.
8887 MaxRequestsPerChild may still not work, but it certainly works
8888 better than it did before this! [Robert Thau]
8890 *) mod_dir.c bug fixes: ReadmeName and HeaderName
8891 work (or work better, at least); over-long description lines
8892 properly terminated. [Mark Cox]
8894 *) http_request.c now calls unescape_url() more places where it
8895 should [Paul Sutton].
8897 *) More directory handling bugs (reported by Cox)
8898 Parent Directory link is now set correctly. [Robert Thau]
8900 Changes with Shambhala 0.5.1 04 Jul 1995
8902 *) Generalized cleanup interface in alloc.c --- any function can be
8903 registered with alloc.c as a cleanup for a resource pool;
8904 tracking of files and file descriptors has been reimplemented in
8905 terms of this interface, so I can give it some sort of a test.
8908 *) More changes in alloc.c --- new cleanup_for_exec() function,
8909 which tracks down and closes all file descriptors which have been
8910 registered with the alloc.c machinery before the server exec()s a
8911 child process for CGI or <!--#exec-->. CGI children now get
8912 started with exactly three file descriptors open. Hopefully,
8913 this cures the problem Rob H. was having with overly persistent
8914 CGI connections. [Robert Thau]
8916 *) Mutual exclusion around the accept() in child_main() --- this is
8917 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
8918 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
8919 This uses fcntl(F_SETLK,...) on the error log descriptor because
8920 flock() on that descriptor won't work on systems which have BSD
8921 flock() semantics, including (I think) Linux 1.3 and Solaris.
8923 This does work on SunOS (when the server is idle, only one
8924 process in the pool is waiting on accept()); it *ought* to work
8925 on the other systems. [Robert Thau]
8927 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
8929 *) sizeof(*sa_client) bugfix from [Rob Hartill]
8931 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
8933 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
8934 be unnecessary if I go to the revised timeout-handling scheme).
8937 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
8938 string) even if none came in with the request. [Robert Thau]
8940 *) CHANGES file added to distribution ;-).
8942 Changes with Shambhala 0.4.5
8944 *) mod_dld --- early dynamic loading support [rst]
8945 *) Add wildcard content handlers for XBITHACK; default_hander now
8946 invoked with that mechanism (as a handler hanging off mod_core) [rst]
8947 *) XBITHACK supported as a wildcard content-handler, and
8948 configurable at run-time (not just at compile time, as in the
8949 "patchy server" releases) [rst]
8951 Changes with Shambhala 0.4.4 30 Jun 1995
8953 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
8954 *) Handle Addtype x/y .z [rst, reported by Cox]
8956 Changes with Shambhala 0.4.3
8958 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
8959 synonymous [rst, terbush]
8961 Changes with Shambhala 0.4.1 28 Jun 1995
8963 *) First-cut virtual host implementation; some refit in the config
8964 reading code, and log management, was necessary to support this [rst]
8965 *) Sub-pool machinery, originally added to avoid excessive storage
8966 allocation on listings of large directories (which turned out to
8967 be the problem that the 0.3 storage accounting was added to
8968 find). Subrequests and mod_dir changed to use subpools. [rst]
8969 *) More memory debugging --- free list consistency checks. [rst]
8970 *) Added err_headers to request_rec, with support elsewhere [rst]
8971 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
8973 Changes with Shambhala 0.3 19 Jun 1995
8975 *) Switch ONE_PROCESS to a runtime command-line option (-X)
8976 *) Don't compile in mod_ai_backcompat by default
8977 *) Switch name of server from Apache to Shambhala in Makefile
8978 *) Add some accounting routines to track memory usage in the pools,
8981 Changes with Shambhala 0.2
8983 *) Set DOCUMENT_ROOT CGI variable
8984 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
8985 *) Add critical section protection to handling of cleanup structures
8987 *) Significant code reorg within the server core to group related
8988 functions together [rst]
8989 *) Correctly handle clients that hang up before sending any request
8991 *) Replace dying child processes. [rst]
8993 Changes with Shambhala 0.1 12 Jun 1995
8995 Major rewrite of the pre-existing "patchy server" codebase, by
8996 Robert Thau (rst). Significant portions of the server code, such
8997 as configuration-file handling and HTTP authentication support,
8998 were ripped out and rewritten from scratch. Code that was not
8999 completely rewritten was significantly altered.
9001 Major changes with this release include:
9003 *) Introduction of the module API; in request handling, the central
9004 machinery just dispatches to various modules, which actually do
9005 most of the work. Configuration handling is similar --- modules
9006 declare their own commands, and the central machinery just
9009 API features from shambhala/0.1 were substantially unchanged in
9010 Apache 1.0 and 1.1. (1.0 API features not yet present in this
9011 release, such as wildcard handlers and subpools, were added in
9012 subsequent Shambhala releases, and were also generally rst's
9015 *) This release included the following modules:
9017 mod_access (access control --- allow and deny directives),
9018 mod_alias (Alias and Redirect commands),
9019 mod_auth (straight HTTP authentication, based on flat-files)
9020 mod_auth_dbm (same, with dbm files)
9021 mod_cgi (CGI scripts and, in this release, ScriptAlias)
9022 mod_common_log (CLF access logs; later renamed mod_log_common)
9023 mod_dir (directory indexing)
9024 mod_include (server-side includes)
9025 mod_mime (AddType directives)
9026 mod_negotiation (content negotiation)
9027 mod_userdir (support for users' public_html directories)
9029 It also included a mod_ai_backcompat, which was a private hack
9030 for back-compatibility with rst's own AI-lab servers.
9032 All of these modules were substantially complete, and functional
9033 or nearly so (a few, which implemented features not in use at
9034 Thau's site, required patches of a few lines).
9036 *) sub-request machinery, to allow modules to determine how other
9037 modules would assign MIME types to a given file, or optionally
9038 serve its content (this is heavily used by mod_dir, mod_include
9039 and mod_negotiation).
9041 *) Resource pool system for keeping track of memory allocated and
9042 files opened in service of a particular request. Much of the
9043 code in the modules (when they weren't rewrites) was adjusted to
9044 replace a pervasive convention of using fixed-size buffers on
9045 the stack with an equally pervasive convention of using memory
9046 allocated with palloc().
9048 *) Reorganization of data structures associated with a given
9049 request to eliminate use of global variables and the troublesome
9050 unmunge_name function (used in NCSA and early Apache releases to
9051 attempt to determine the URI which mapped to a given filename
9052 --- a difficult proposition, given that it is easy to produce
9053 setups in which multiple URIs map to the same file).
9055 *) Source files renamed and rearranged
9057 *) Very simple pre-forking behavior --- parent process forked off a
9058 fixed number of children, and then just waited for SIGHUP.
9060 *) Other more minor changes too numerous to list.
9062 This release included modified versions of a lot of code from the
9063 Apache 0.6.4 public release, plus an early pre-forking patch
9064 codeveloped by Robert Thau and Rob Hartill.
9066 Changes with Apache 0.7.3 20 Jun 1995
9068 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
9069 were incorporated by Rob Hartill on the main branch while Robert Thau
9070 worked on the Shambhala rewrite above. Most were merged into the
9071 Shambala architecture after Apache 0.8.0.
9073 Changes with Apache 0.6.4 13 May 1995
9075 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
9078 Changes with Apache 0.5.1 10 Apr 1995
9080 Changes with Apache 0.4 02 Apr 1995
9082 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
9085 Changes with Apache 0.3 24 Mar 1995
9087 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
9090 Changes with Apache 0.2 18 Mar 1995
9092 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
9093 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
9094 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
