1 Changes with Apache 2.0b1
3 *) Don't disable threads just because we are using the prefork MPM.
4 If somebody wants to compile without threads, they must now add
5 --disable-threads to the configure command line. [Ryan Bloom]
7 *) Begin to move the calls to update_child_status into common code, so
8 that each individual MPM does not need to update the scoreboard itself.
11 *) Allow mod_tls to compile under Unix boxes where openssl has been
12 installed to the system include files.
13 [Gomez Henri <new-httpd@slib.fr>]
15 *) Cleanup the mod_tls configure process. This should remove any need
16 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
17 configure doesn't check that yet. [Ryan Bloom]
19 *) Add a very early prototype of SSL support (in mod_tls.c). It is
20 vital that you read modules/tls/README before attempting to build
23 *) Fix a potential seg fault on all platforms. David Reid fixed this
24 on BEOS, but the problem could happen anywhere, so we don't want
25 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
27 *) Add new LogFormat directive, %D, to log time it takes to serve a
28 request in microseconds. [Bill Stoddard]
30 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
31 SetOutputFilter. This corresponds nicely with the other Set
32 directives, which operate on containers while the Add* directives
33 tend to work directly on extensions. [Ryan Bloom]
35 *) Cleanup the header handling a bit. This uses the apr_brigade_*
36 functions for the buffering so that we don't need to compute
37 the length of the headers before we actually create the header
40 *) Allow filters to buffer data using the ap_f* functions. These have
41 become macros that resolve directly to apr_brigade_*.
44 *) Get the Unix MPM's to do a graceful restart again. If we are going
45 to register a cleanup with ap_cleanup_scoreboard, then we have to
46 kill the cleanup with the same function, and that function can't be
49 *) Install all required header files. Without these, it was not
50 possible to compile some modules outside of the server.
53 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
54 forward from 1.3 to 2.0, we missed a single line, which broke regex
57 *) We have a poor abstraction in the protocol. This is a temporary
58 hack to fix the bug, but it will need to be fixed for real. If
59 we find an error while sending out a custom error response, we back
60 up to the first non-OK request and send the data. Then, when we send
61 the EOS from finalize_request_protocol, we go to the last request,
62 to ensure that we aren't sending an EOS to a request that has already
63 received one. Because the data is sent on a different request than
64 the EOS, the error text never gets sent down the filter stack. This
65 fixes the problem by finding the last request, and sending the data
66 with that request. [Ryan Bloom]
68 *) Make the server status page show the correct restart time, and
69 thus the proper uptime. [Ryan Bloom]
71 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
72 should reduce the amount of duplicate code that is required to
74 [Paul J. Reder <rederpj@raleigh.ibm.com>]
76 *) ap_new_connection() closes the socket and returns NULL if a socket
77 call fails. Usually this is due to a connection which has been
80 *) Move the Apache version information out of httpd.h and into release.h.
81 This is in preparation for the first tag with the new tag and release
84 *) Begin restructuring scoreboard code to enable adding back in
85 the ability to use IPC other than shared memory.
86 Get mod_status working on Windows again. [Bill Stoddard]
88 *) Make mod_status work with 2.0. This will work for prefork,
89 mpmt_pthread, and dexter. [Ryan Bloom]
91 *) Correct a typo in httpd.conf.
92 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
94 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
96 *) Get the correct IP address if ServerName isn't set and we can't
97 find a fully-qualified domain name at startup.
98 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
100 *) Make mod_cgid work with SuExec. [Ryan Bloom]
102 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
103 'extra' stat's for user/group since they should never occur, and now
104 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
105 volumes. [William Rowe]
107 *) Adopt apr features to simplify mod_includes. This changes the
108 behavior of the USER_NAME variable, unknown uid's are now reported
109 as USER_NAME="<unknown>" rather than the old user#000 result.
110 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
112 *) Adopt apr features for simplifing mod_userdir, and accept the new
113 Win32/OS2 exceptions without hiccuping. [William Rowe]
115 *) Replace configure --with-optim option by using and saving the
116 environment variable OPTIM instead. This is needed because configure
117 options do not support multiple flags separated by spaces.
120 *) Fix some byterange handling. If we get a byte range that looks like
121 "-999999" where that is past the end of the file, we should return
122 a PARTIAL CONTENT status code, and return the whole file as one big
123 byterange. This matches the 1.3 handling now. [Ryan Bloom]
125 *) Make the error bucket a real meta-data bucket. This means that the
126 bucket length is 0, and a read returns NULL data. If one of these
127 buckets is passed down after the headers are sent, this data will
128 just be ignored. [Greg Stein]
130 *) The prefork MPM wasn't killing child processes correctly if a restart
131 signal was received while the process was serving a request. The child
132 process would become the equivalent of a second parent process. If
133 we break out of the accept loop, then we need to do die after cleaning
134 up after ourselves. [Ryan Bloom]
136 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
137 restarts. [Ryan Bloom]
139 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
140 the most optimal APR_FINFO_wanted bits. This spares Win32 from
141 performing very expensive owner, group and permission lookups
142 and allows the server to function until these apr_finfo_t fields
143 are implemented under Win32. [William Rowe]
145 *) Support for typedsafe optional functions - that is functions exported by
146 optional modules, which, therefore, may or may not be present, depending
147 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
148 for sample code. [Ben Laurie]
150 *) filters can now report an HTTP error to the server. This is done
151 by sending a brigade where the first bucket is an error_bucket.
152 This bucket is a simple bucket that stores an HTTP error and
153 a string. Currently the string is not used, but it may be needed
154 to output an error log. The http_header_filter will find this
155 bucket, and output the error text, and then return
156 AP_FILTER_ERROR, which informs the server that the error web page
157 has already been sent. [Ryan Bloom]
159 *) If we get an error, then we should remove all filters except for
160 those critical to serving a web page. This fixes a bug, where
161 error pages were going through the byterange filter, even though
162 that made no sense. [Ryan Bloom]
164 *) Relax the syntax checking of Host: headers in order to support
165 iDNS. PR#6635 [Tony Finch]
167 *) Cleanup the byterange filter to use the apr_brigade_partition
168 and apr_bucket_copy functions. This removes a lot of very messy
169 code, and hopefully makes this filter more stable.
172 *) Remove AddModule and ClearModuleList directives. Both of these
173 directives were used to ensure that modules could be enabled
174 in the correct order. That requirement is now gone, because
175 we use hooks to ensure that modules are in the correct order.
178 *) When SuExec is specified, we need to add it to the list of
179 targets to be built. If we don't, then any changes to the
180 configuration won't affect SuExec, unless 'make suexec' is
181 specifically run. [Ryan Bloom]
183 *) Cleaned out open_file from mod_file_cache, as apr now accepts
184 the APR_XTHREAD argument to open a file for consumption by
185 parallel threads on win32. [William Rowe]
187 *) Correct a bug in determining when we follow symlinks. The code
188 expected a stat -1 result, not an apr_status_t positive error.
189 Also check if the APR_FINFO_USER fields are valid before we
190 follow the link. [William Rowe]
192 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
193 mpm_common.c. These functions are only valid on some platforms,
194 so they should not be in the main-line code. [Ryan Bloom]
196 *) Remove ap_chdir_file(). This function is not thread-safe,
197 and nobody is currently using it. [Ryan Bloom]
199 *) Do not try to run make depend if there are no .c files in the
200 current directory, doing so makes `make depend` fail.
203 *) Update highperformance.conf to work with either prefork or
204 pthreads mpms. [Greg Ames]
206 *) Stop checking to see if this is a pipelined request if we know
207 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
208 This keeps us from making an extra read call when serving a 1.0
209 request. [Ryan Bloom and Greg Stein]
211 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
212 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
213 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
215 *) Fix the RFC number mentioned when complaining about a missing
216 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
218 *) Fix an endless loop in ab which occurred when ab was posting
219 and the server dropped the connection unexpectedly.
222 *) Fix a segfault while handling request bodies in ap_http_filter().
223 This problem has been seen with mod_dav usage as well as with
224 requests where the body was just being discarded. [Jeff Trawick]
226 *) Some adjustment on the handling and automatic setting (via
227 hints.m4) of various compilation flags (eg: CFLAGS). Also,
228 add the capability to specify flags (NOTEST_CFLAGS and
229 NOTEST_LDFLAGS) which are used to compile Apache, but
230 not used during the configuration process. Useful for
231 flags like "-Werror". [Jim Jagielski]
233 *) Stop using environment variables to force debug mode or
234 no detach. We now use the -D command line argument to
235 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
236 [Greg Stein, Ryan Bloom]
238 *) Change handlers to use hooks. [Ben Laurie]
240 *) Stop returning copies of filenames from both apr_file_t and
241 apr_dir_t. We pstrdup the filenames that we store in the
242 actual structures, so we don't need to pstrdup the strings again.
245 *) mod_cgi: Fix some problems where the wrong error value was being
246 traced. [Jeff Trawick]
248 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
251 *) Add generic hooks. [Ben Laurie]
253 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
255 *) Fix a segfault caused by mod_ext_filter when the external filter
256 program does not exist. [Jeff Trawick]
258 *) Fix an output truncation error when on an HTTP >= 1.0 request an
259 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
260 was served through mod_charset_lite (or anything else that would
261 create a transient bucket in this size range). ap_bucket_make_heap()
262 silently failed (fixed), transient_setaside() discovered it, but
263 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
265 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
266 is that some browsers send extra lines at the end of POST requests, and
267 we don't want to delay sending data back to the user just because the
268 browser isn't well behaved. [Ryan Bloom]
270 *) Get SuEXEC working again. We can't send absolute paths to suExec
271 because it refuses to execute those programs. SuEXEC also wasn't
272 always recognizing configuration changes made using the autoconf
275 *) Allow the buildconf process to find the config.m4 files in the correct
276 order. Basically, we can now name config.m4 files as config\d\d.m4,
277 and we will sort them correctly when inserting them into the build
278 process. [Ryan Bloom]
280 *) Get mod_cgid to use apr calls for creating the actual CGI process.
281 This also allows mod_cgid to use ap_os_create_priviledged_process,
282 thus allowing for SuExec execution from mod_cgid. Currently, we do
283 not support everything that standard SuExec supports, but at least
284 it works minimally now. [Ryan Bloom]
286 *) Allow SuExec to be configured from the ./configure command line.
289 *) Update some of the docs in README and INSTALL to reflect some of
290 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
292 *) If we get EAGAIN returned from the call to apr_sendfile, then we
293 need to call sendfile again. This gets us serving large files
294 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
296 *) Get the support programs building cleanly again.
297 [Cliff Woolley <cliffwoolley@yahoo.com>]
299 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
300 current directory logic now backs up over bin/ to determine the
301 server root from the Apache.exe path.
303 *) Apache/Win32 now follows the standard conventions of mod_foo.so
304 loadable modules, dynamic libs are all named libfoo.dll, and the
305 makefile.win populates the include, lib and libexec directories.
307 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
308 Apache gets IPv6 listening sockets by default. Additionally, the
309 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
310 numeric address strings (e.g., "Listen [fe80::1]:8080").
313 *) Modify the install directory layout. Modules are now installed in
314 modules/. Shared libraries should be installed in libraries/, but
315 we don't have any of those on Unix yet. All install directories
316 are modifyable at configure time. [Ryan Bloom]
318 *) Install all header files in the same directory on Unix. [Ryan Bloom]
320 *) Get the functions in server/linked into the server, regardless of
321 which modules linked into the server. This uses the same hack
322 for Apache that we use for APR and apr-util to ensure all of the
323 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
324 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
325 the scripts a bit easier.
328 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
329 on the query, and remove IPv4 dependencies. [Jeff Trawick]
331 *) Get all of the auth modules to the point that they will install and
332 be loadable into the server. Our new build/install mechanism expects
333 that all modules will have a common name format. The auth modules
334 didn't use that format, so we didn't install them properly.
337 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
338 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
340 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
342 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
343 after the end of the response. [Ryan Bloom]
345 *) Get byterange requests working with responses that do not have a
346 content-length. Because of the way byterange requests work, we have to
347 have all of the data before we can actually do the byterange, so we
348 can compute the content-length in the byterange filter.
351 *) Get exe CGI's working again on Windows.
354 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
355 they keep track of whether or not their post config hook has been
356 called before. Instead of a static variable (which is replaced when
357 the DSO is loaded a second time), use userdata in the process pool.
360 Changes with Apache 2.0a9
362 *) Win32 now requires perl to complete the final install step for users
363 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
364 and installs the conf, htdocs and htdocs/manual directories.
367 *) Make mod_include use a hash table to associate directive tags with
368 functions. This allows modules to implement their own SSI tags easily.
369 The idea is simple enough, a module can insert it's own tag and function
370 combination into a hash table provided by mod_include. While mod_include
371 parses an SSI file, when it encounters a tag in the file, it does a
372 hash lookup to find the function that implements that tag, and passes
373 all of the relevant data to the function. That function is then
374 responsible for processing the tag and handing the remaining data back
375 to mod_include for further processing.
376 [Paul J. Reder <rederpj@raleigh.ibm.com>]
378 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
379 fewer parameters: the local and remote socket addresses were removed
380 from the parameter list because all required information is available
381 via the APR socket. [Jeff Trawick]
383 *) Distribution directory structure reorganized to reflect a
384 normal source distribution with external install targets.
387 *) The MPMs that need multiple segments of shared memory now create
388 two apr_shmem_t variables, one for each shared memory allocation.
389 the problem is that we can't determine how much memory will be required
390 for shared memory allocations once we try to allocate more than one
391 variable. The MM code automatically aligns the shared memory allocations,
392 so we end up needing to pad the amount of shared memory we want based
393 on how many variables will be allocated out of the shared memory segment.
394 It is just easier to create a second apr_shmem_t variable, and two
398 *) Cleanup the export list a bit. This creates a single unified list of
399 functions exported by APR. The export list is generated at configure
400 time, and that list is then used to generate the exports.c file.
401 Because of the way the export list is generated, we only export those
402 functions that are valid on the platform we are building on.
405 *) Enable logging the cookie with mod_log_config
406 [Sander van Zoest <sander@covalent.net>]
408 *) Fix a segfault in mod_info when it reaches the end of the configuration.
411 *) Added lib/aputil/ as a placeholder for utility functions which are not
412 specific to the Apache HTTP Server (but do not make sense with APR).
413 The first utility is "apu_dbm": a set of functions to work with DBM
414 files. This first version can be compiled for SDBM or GDBM databases.
417 *) Complete re-write of mod_include. This makes mod_include a filter that
418 uses buckets directly. This has now served the FAQ correctly.
419 [Paul Reder <rederpj@raleigh.ibm.com>]
421 *) Allow modules to specify the first filter in a sub_request when
422 making the sub_request. This keeps modules from having to change the
423 output_filter immediately after creating the sub-request, and therefore
424 skip the sub_req_output_filter. [Ryan Bloom]
426 *) Update ab to accept URLs with IPv6 literal address strings (in the
427 format described in RFC 2732), and to build Host header fields in
428 the same format. This allows IPv6 literal address strings to be
429 used with ab. This support has been tested against Apache 1.3 with
430 the KAME patch, but Apache 2.0 does not yet work with this format
431 of the Host header field. [Jeff Trawick]
433 *) Accomodate an out-of-space condition in the piped logs and the
434 rotatelogs.c code, and no longer churn log processes for this
435 condition. [Victor J. Orlikowski]
437 *) Add support for partial writes with apr_sendfile() to core_output_filter.
440 Changes with Apache 2.0a8
442 *) Add a directive to mod_mime so that filters can be associated with
446 *) Get multi-views working again. We were setting the path_info
447 field incorrectly if we couldn't find the specified file.
450 *) Fix 304 processing. The core should never try to send the headers
451 down the filter stack. Always, just setup the table in the request
452 record, and let the header filter convert it to data that is ready
456 *) More fixes for the proxy. There are still bugs in the proxy code,
457 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
461 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
464 *) APR: Add new apr_getopt_long function to handle long options.
465 [B. W. Fitzpatrick <fitz@red-bean.com>]
467 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
468 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
469 hostname resolution/address string parsing and building
470 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
471 of one of the apr_sockaddr_t structures for a socket. Change
472 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
474 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
475 I have proxied pages with it, cleanup will commence soon.
478 *) Make the proxy work with filters. This isn't perfect, because we
479 aren't dealing with the headers properly. [Ryan Bloom]
481 *) Do not send a content-length iff the C-L is 0 and this is a head
482 request. [Ryan Bloom]
484 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
485 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
487 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
489 *) Get the default_handler to stop trying to deal with HEAD requests.
490 The idea is to let the content-length filter compute the C-L before
491 we try to send the data. If we can get the C-L correctly, then we
492 should send it in the HEAD response.
495 *) The Header filter can now determine if a body should be sent based
496 on r->header_only. The general idea of this is that if we delay
497 deciding to send the body, then we might be able to compute the
498 content-length correctly, which will help caching proxies to cache
499 our data better. Any handler that doesn't want to try to compute
500 the content-length can just send an EOS bucket without data and
501 everything will just work.
504 *) Add the referer to the error log if one is available.
505 [Markus Gyger <mgyger@itr.ch>]
507 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
508 change, the root of the configuration tree has been exposed to modules
510 [Ryan Morgan <rmorgan@covalent.net>]
512 *) Get the core_output_filter to use the bucket interface directly.
513 This keeps us from calling the content-length filter multiple times
514 for a simple static request.
517 *) We are sending the content-type correctly now.
518 [Ryan Bloom and Will Rowe]
520 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
521 a bogus bytes-sent value when the only thing being sent was trailers
522 and writev() returned an error (or EAGAIN). [Jeff Trawick]
524 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
525 hints file to determine which platforms define
526 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
529 *) APR: add apr_get_home_directory() [Jeff Trawick]
531 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
533 *) Not all platforms have INADDR_NONE defined by default. Apache
534 used to make this check and define INADDR_NONE if appropriate,
535 but APR needs the check too, and I suspect other applications will
536 as well. APR now defines APR_INADDR_NONE, which is always a valid
537 value on all platforms.
538 [Branko Èibej <brane@xbc.nu>]
540 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
541 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
543 *) Relax the syntax checking of Host: headers in order to support
544 iDNS. PR#6635 [Tony Finch]
546 *) When reading from file buckets we convert to an MMAP if it makes
547 sense. This also simplifies the default handler because the
548 default handler no longer needs to try to create MMAPs.
551 *) BUFF has been removed from the main server. The BUFF code will remain
552 in the code until it has been purged from the proxy module as well.
555 *) Byteranges have been completely re-written to be a filter. This
556 has been tested, and I believe it is working correctly, but it could
557 doesn't work for the Adobe Acrobat plug-in. The output almost matches
558 the output from 1.3, the only difference being that 1.3 includes
559 a content-length in the response, and this does not.
562 *) APR read/write functions and bucket read functions now operate
563 on unsigned integers, instead of signed ones. It doesn't make
564 any sense to use signed ints, because we return the error codes,
565 so if we have an error we should report 0 bytes read or written.
568 *) Always compute the content length, whether it is sent or not.
569 The reason for this, is that it allows us to correctly report
570 the bytes_sent when logging the request. This also simplifies
571 content-length filter a bit, and fixes the actual byte-reporing
572 code in mod_log_config.c
575 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
576 it says, because it was only used by EOS and FLUSH buckets. Since
577 neither of those are required at the end of a brigade, this was
578 really signifying FLUSH_THE_DATA, but that can be determined better
579 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
580 buckets now return a length of 0, which is actually the amount of data
581 read, so they make more sense.
584 *) Allow the core_output_filter to save some data past the end of a
585 request. If we get an EOS bucket, we only send the data if it
586 makes sense to send it. This allows us to pipeline request
587 responses. As a part of this, we also need to allocate mmap
588 buckets out of the connection pool, not the request pool. This
589 allows the mmap to outlive the request.
592 *) Make blocking and non-blocking bucket reads work correctly for
593 sockets and pipes. These are the only bucket types that should
594 have non-blocking reads, because the other bucket types should
595 ALWAYS be able to return something immediately.
598 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
599 server, but use Ctrl+Break to initiate a graceful restart
600 instead of duplicating behavior. [John Sterling]
602 *) Patch mod_autoindex to set the Last-Modified header based on
603 the directory's mtime, and add the ETag header. [William Rowe]
605 *) Merge the 1.3 patch to add support for logging query string in
606 such a way that "%m %U%q %H" is the same as "%r".
609 *) Port three log methods from mod_log_config 1.3 to 2.0:
610 CLF compliant '-' byte count, method and protocol.
613 *) Add a new LogFormat directive, %c, that will log connection
614 status at the end of the response as follows:
615 'X' - connection aborted before the response completed.
616 '+' - connection may be kept-alive by the server.
617 '-' - connection will be closed by the server.
620 *) Expand APR for WinNT to fully accept and return utf-8 encoded
621 Unicode file names and paths for Win32, and tag the Content-Type
622 from mod_autoindex to reflect that charset if the the feature
623 macro APR_HAS_UNICODE_FS is true. [William Rowe]
625 *) Compute the content length (and add appropriate header field) for
626 the response when no content length is available and we can't use
627 chunked encoding. [Jeff Trawick]
629 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
630 so that content input filters get dechunked data when using
631 the default handler. Also removed REQUEST_CHUNKED_PASS.
634 *) Add mod_ext_filter as an experimental module. This module allows
635 the administrator to use external programs as filters. Currently,
636 only filtering of output is supported. [Jeff Trawick]
638 *) Most Apache functions work on EBCDIC machines again, as protocol
639 data is now translated (again). [Jeff Trawick]
641 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
642 the EBCDIC support. They are noops on ASCII machines, so this
643 type of translation doesn't have to be surrounded by #ifdef
644 CHARSET_EBCDIC. [Jeff Trawick]
646 *) Fix mod_include. tag commands work again, and the server will
647 send the FAQ again. This also allows mod_include to set aside
648 buckets that include partial buckets.
649 [Ryan Bloom and David Reid]
651 *) Add suexec support back. [Manoj Kasichainula]
653 *) Lingering close now uses the socket directly instead of using
654 BUFF. This has been tested, but since all we can tell is that it
655 doesn't fail, this needs to be really hacked on.
658 *) Allow filters to modify headers and have those headers be sent to
659 the client. The idea is that we have an http_header filter that
660 actually sends the headers to the network. This removes the need
661 for the BUFF to send headers.
664 *) Charset translation: mod_charset_lite handles translation of
665 request bodies. Get rid of the xlate version of ap_md5_digest()
666 since we don't compute digests of filtered (e.g., translated)
667 response bodies this way anymore. (Note that we don't do it at
668 all at the present; somebody needs to write a filter to do so.)
671 *) Input filters and ap_get_brigade() now have a input mode parameter
672 (blocking, non-blocking, peek) instead of a length parameter.
675 *) Update the mime.types file to the registered media types as
676 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
679 *) Namespace protect some macros declared in ap_config.h
682 *) Support HTTP header line folding with input filtering.
685 *) Mod_include works again. This should still be re-written, but at
686 least now we can serve an SHTML page again.
689 *) Begin to remove BUFF from the core. Currently, we keep a pointer
690 to both the BUFF and the socket in the conn_rec. Functions that
691 want to use the BUFF can, functions that want to use the socket,
692 can. They point to the same place.
695 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
696 [Tomas "Ögren" <stric@ing.umu.se>]
698 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
699 associated pool goes away. (APR pipes on OS/2 were already had this
700 logic.) This resolvs a fatal file descriptor leak with CGIs.
703 *) The final line of the config file was not being read if there was
704 no \n at the end of it. This was caused by apr_fgets returning
705 APR_EOF even though we had read valid data. This is solved by
706 making cfg_getline check the buff that was returned from apr_fgets.
707 If apr_fgets return APR_EOF, but there was data in the buf, then we
708 return the buf, otherwise we return NULL.
711 *) Piped logs work again in the 2.0 series.
714 *) Restore functionality broken by the mod_rewrite security fix:
715 rewrite map lookup keys and default values are now expanded
716 so that the lookup can depend on the requested URI etc.
717 PR #6671 [Tony Finch]
719 *) Tighten up the syntax checking of Host: headers to fix a
720 security bug in some mass virtual hosting configurations
721 that can allow a remote attacker to retrieve some files
722 on the system that should be inaccessible. [Tony Finch]
724 *) Add a pool bucket type. This bucket is used for data allocated out
725 of a pool. If the pool is cleaned before the bucket is destroyed, then
726 the data is converted to a heap bucket, allowing it to survive the
730 *) Add a flush bucket. This allows modules to signal that the filters
731 should all flush whatever data they currently have. There is no way
732 to actually force them to do this, so if a filter ignores this bucket,
733 that's life, but at least we can try with this.
736 *) Add an output filter for sub-requests. This filter just strips the
737 EOS bucket so that we don't confuse the main request's core output
738 filter by sending multiple EOS buckets. This change also makes sub
739 requests start to send EOS buckets when they are finished.
742 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
743 makes ap_bucket_destroy a return void, which is okay because it
744 used to always return APR_SUCCESS, and nobody ever checked its
746 [Cliff Woolley <cliffwoolley@yahoo.com>]
748 *) Remove the index into the bucket-type table from the buckets
749 structure. This has now been replaced with a pointer to the
750 bucket_type. Also add some macros to test the bucket-type.
753 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
754 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
755 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
756 All _VAR_ flavors changes to _DATA to be absolutely clear.
759 *) Add support for /, //, //servername and //server/sharename
760 parsing of <Directory> blocks under Win32 and OS2.
761 [Tim Costello, William Rowe, Brian Harvard]
763 *) Remove the function pointers from the ap_bucket type. They have been
764 replaced with a global table. Modules are allowed to register bucket
765 types and use then use those buckets.
768 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
769 once we finish writing the request body to the cgi child process;
770 otherwise, the client doesn't hit EOF on stdin. Small request bodies
771 worked without this change (for reasons I don't understand), but large
772 ones didn't. [Jeff Trawick]
774 *) Remove file bucket specific information from the ap_bucket type.
775 This has been moved to a file_bucket specific type that hangs off
776 the data pointer in the ap_bucket type.
779 *) Input filtering now has a third argument. This is the amount of data
780 to read from lower filters. This argument can be -1, 0, or a positive
781 number. -1 means give me all the data you have, I'll deal with it and
782 let you know if I need more. 0 means give me one line and one line
783 only. A positive number means I want no more than this much data.
785 Currently, only 0 and a positive number are implemented. This allows
786 us to remove the remaining field from the conn_rec structure, which
790 *) Big cleanup of the input filtering. The goal is that http_filter
791 understands two conditions, headers and body. It knows where it is
792 based on c->remaining. If c->remaining is 0, then we are in headers,
793 and http_filter returns a line at a time. If it is not 0, then we are
794 in body, and http_filter returns raw data, but only up to c->remaining
795 bytes. It can return less, but never more.
796 [Greg Ames, Ryan Bloom, Jeff Trawick]
798 *) mod_cgi: Write all of the request body to the child, not just what
799 the kernel would accept on the first write. [Jeff Trawick]
801 *) Back out the change that moved the brigade from the core_output_filters
802 ctx to the conn_rec. Since all requests over a given connection
803 go through the same core_output_filter, the ctx pointer has the
807 *) Fix another bug in the send_the_file() read/write loop. A partial
808 send by apr_send would cause unsent data in the read buffer to
809 get clobbered. Complete making send_the_file handle partial
810 writes to the network.
813 *) Fix a couple of type fixes to allow compilation on AIX again
814 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
816 *) Fix bug in send_the_file() which causes offset to be ignored
817 if there are no headers to send.
820 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
821 filter. Useful for supporting Windows 9* with a binary
822 compiled on Windows NT.
825 Changes with Apache 2.0a7
827 *) Reimplement core_output_filter to buffer/save bucket brigades
828 across multiple calls to the core_filter. The brigade will be
829 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
830 thresholds are hit or the EOS bucket is received.
833 *) Create experimental filter (buffer_filter) that coalesces bytes
834 into one large buffer before invoking the next filter in the
835 chain. This filter is particularly useful with the current
836 implementation of mod_autoindex when it inserted above the
837 chunk_filter. mod_autoindex generates a lot of brigades that
838 containing buckets holding just a few bytes each. The
839 buffer_filter coalesces these buckets into a single large bucket.
842 *) Add apr_sendfile() support into the core_output_filter.
845 *) Add apr_sendv() support into the core_output_filter.
848 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
849 [Mike Abbott <mja@sgi.com>]
851 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
852 make much sense, because Apache uses buckets instead of BUFFs now.
855 *) send_the_file now falls back to a read/write loop on platforms that
856 do not have sendfile.
857 [Ryan Bloom and Brian Havard]
859 *) Install apachectl correctly, and substitute the proper values so
860 that it works again. [Ryan Bloom]
862 *) Better(??) handle platforms that lack sendfile().
865 *) APR now has UUID generation/formatting/parsing support.
868 *) Begin the http_filter. This is an input filter that understands
869 the absolute basic amount required to parse an HTTP Request. The
870 goal is to be able to split headers from request body before passing
871 the data back to the other filters.
874 *) Bring forward from 1.3.13 the config directory implementation
877 *) install apxs if it is created
880 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
881 conversions. [William Rowe]
883 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
884 ap_add_output_filter(). [Jeff Trawick]
886 *) Multiple build and configuration fixes
889 -add datadir and localstatedir substitutions
891 -fix logfilename misspelling
892 -fix evaluation of installation dir variables and
893 -replace $foobar by $(foobar) to be usefull in the makefile
897 -add rules for cross-compiling in rules.mk. Okay, rule to check for
898 $CC_FOR_BUILD is still missing
899 -use CHECK_TOOL instead of CHECK_PROG for ranlib
900 -add missing "AR=@AR@" to severaly Makefile.in's
901 -cache result for "struct rlimit"
902 -compile all helper programs with native and cross compiler
903 and use the native version to generate header file
904 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
906 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
908 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
910 *) Fix a bug where a client which only sends \n to delimit header
911 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
912 message. Start working on ebcdic co-existance with input
914 [William Rowe, Greg Ames]
916 *) If mod_so is enabled in the server always create libexec, even
917 if there are no modules installed in this directory. This is a
918 requirement for APXS to work correctly.
921 *) Connection oriented output filters are now stored in the
922 conn_rec instead of the request_rec. This allows us to add the
923 output filter in the pre-connection phase instead of the
924 post_read_request phase, which keeps us from trying to write an
925 error page before we have a filter to write to the network.
926 [Ryan Bloom, Jeff Trawick, and Greg Ames]
928 *) Cleaning up an mmap bucket no longer deletes the mmap. An
929 mmap can be used across multiple buckets (default_handler with
930 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
931 the mmap itself can't be associated with the bucket.
934 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
937 *) Radical surgery to improve mod_isapi support under Win32.
938 Includes a number of newer ServerSupportFunction calls, support
939 for ReadClient (in order to retrieve POSTs greater than 48KB),
940 and general bug fixes to more reliably load ISAPI .dll's and
941 prevent leaking handle resources. Note: There are still
942 discrepancies between IIS's and Apache's ServerVariables, and
943 async calls are still not supported. Additional warnings are
944 logged to facilitate debugging of unsupported ISAPI calls.
947 *) Add input filtering to Apache. The basic idea for the input
948 filters is the same as the ideas for output filters. The biggest
949 difference is that instead of calling ap_pass_brigade, ap_get_brigade
950 should be called, and the order of execution for the filter itself is
951 different. When writing an output filter, a brigade is passed in,
952 and filters operate directly on that brigade, when done, they call
953 ap_pass_brigade. Input filters are the exact opposite. Because input
954 is not a push operation, filters first call ap_get_brigade. When this
955 function returns, the input filter will be left with a valid brigade.
956 The input filter should then operate on the brigade, and return.
959 *) Fix building on BSD/OS using its native make. The build system
960 falls back to the BSD .include directive on that host platform.
963 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
964 SHA1 and plaintext password encodings. Make feature tests a
965 bit more flexible. [William Rowe]
967 *) Charset translation: mod_charset_lite handles output content
968 translation in a filter. mod_charset_lite no longer ignores
969 subrequests. A bunch of cruft related to BUFF's support for
970 translating request and response bodies was removed.
973 *) Move the addition of the CORE filter to the post_read_request
974 hook in http_core.c. This removes the need to add the filter in
975 multiple places and allows for an SSL module to be added much
976 simpler. [Ryan Bloom]
978 *) Fix a security problem that affects certain configurations of
979 mod_rewrite. If the result of a RewriteRule is a filename that
980 contains expansion specifiers, especially regexp backreferences
981 $0..$9 and %0..%9, then it may be possible for an attacker to
982 access any file on the web server. [Tony Finch]
984 *) Fix a bug where errors that are detected during early request parsing
985 don't produce visible HTTP error messages at the browser, because
986 the core_filter wasn't present. [Greg Ames]
988 *) Provide apr_socklen_t as a portability aid.
989 [Victor J. Orlikowski]
991 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
992 as well as a comment arg to the add, adduser and update cmds.
993 update allows the user to clear or preserve pw/groups/comment.
994 Fixed a bug in dbmmanage that prevented the check option from
995 parsing a password followed by :group... text. Corrected the
996 seed calcualation for Win32 systems, and added -lsdbm support.
999 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
1002 *) Avoid a segfault when parsing .htaccess files. An
1003 uninitialized tree pointer was passed to ap_build_config().
1006 *) Change the way that inet_addr & inet_network are checked for
1007 in APR's configure process to allow BeOS BONE to correctly
1008 find them. With this change BeOS BONE now builds from source
1009 with no problems. [David Reid]
1011 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
1012 the end of the parameters to execve() was stored in the wrong
1013 location, overlaying the storage beyond the newargs[] array and
1014 also passing uninitialized storage to execve(), which would
1015 sometimes fail with EFAULT. [Jeff Trawick]
1017 *) Fix a bug parsing configuration file containers. With a sequence
1018 like this in the config file
1020 <IfModule mod_kilroy.c>
1023 <IfModule mod_lovejoy.c>
1028 the second container would be terminated at the blank line due to
1029 sediment in the buffer from reading the prior </IfModule> and an
1030 error message would be generated for the real </IfModule> for the
1031 second container. Also due to this problem, any two characters
1032 could be used for "</" in the close of a container.
1035 *) ap_add_filter prototype changed to remove the ctx pointer. The
1036 pointer still remains in the filter structure, but it can not be
1037 a part of the ap_add_filter prototype. The reason is that when
1038 the core uses AddFilter to add a filter to the stack it doesn't
1039 know how to allocate the ctx pointer, or even how much memory should
1040 be allocated. The filters will have to be responsible for allocating
1041 the ctx memory when they need it.
1044 *) Add an AddFilter directive. This directive takes a list of filters
1045 that should be activated for the requested resource.
1048 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
1049 some other platforms). [Jeff Trawick]
1051 *) Modify mod_include to be a filter. Currently, it has only been tested
1052 on actual files, but it should work for CGI scripts too.
1055 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
1056 writes. apr_flush() for Unix: handle interrupted writes.
1059 *) NameVirtualHost can now take "*" as an argument instead of
1060 an IP address. This allows you to create a purely name-based
1061 virtual hosting server that does not have any IP addresses in
1062 the configuration file and which ignores the local address
1063 of any connections. PR #5595, PR #4455 [Tony Finch]
1065 *) Fix some compile warnings in mod_mmap_static.c
1066 [Mike Abbott <mja@sgi.com>]
1068 *) Fix chunking problem with CGI scripts. The general problem was that
1069 the CGI modules were adding an EOS bucket and then the core added an
1070 EOS bucket. The chunking filter finalizes the chunked response when it
1071 encounters an EOS bucket. Because two EOS buckets were sent, we
1072 finalized the response twice. The fix is to make sure we only send one
1073 EOS, by utilizing a flag in the request_rec.
1076 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
1077 and Win32. Previously, the first read from an apr_file_t set up via
1078 apr_put_os_file() would return a '\0'. [Jeff Trawick]
1080 *) Mod_cgid now creates a single element bucket brigade, with a pipe
1081 bucket, instead of using BUFF's and ap_r*.
1084 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
1085 [Mike Abbott <mja@sgi.com>]
1087 *) Remove ap_bopenf from buff code. This required modifying the file_cache
1088 code to use APR file's directly instead of going through BUFFs.
1091 *) Fix compile break on some platforms for mod_mime_magic.c
1092 [John K. Sterling <sterling@covalent.net>]
1094 *) Fix merging of AddDefaultCharset directive.
1095 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
1097 *) Minor revamp of the rlimit sections of code. We now test
1098 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
1099 is now "available" even if the platform doesn't support
1100 the rlimit family (it's just a noop though). [Jim Jagielski]
1102 *) Migrate the pre-selection of which MPM to use for specific
1103 platforms to hints.m4, which contains (or should contain)
1104 all platform specific "hints". [Jim Jagielski]
1106 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
1109 *) Add tables with non-string/binary values to APR.
1112 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
1115 *) Update PCRE to version 3.2. [Ryan Bloom]
1117 *) Change the way buckets' destroy functions are called so that
1118 they can be more directly used when changing the type of a
1119 bucket in place. [Tony Finch]
1121 *) Add generic support for reference-counting the resources used by
1122 buckets, and alter the HEAP and MMAP buckets to use it. Change
1123 the way buckets are initialised to support changing the type of
1124 buckets in place, and use it when setting aside TRANSIENT buckets.
1125 Change the implementation of TRANSIENT buckets so that it can be
1126 mostly shared with IMMORTAL buckets, which are now implemented.
1129 Changes with Apache 2.0a6
1131 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
1133 *) Add a chunking filter to Apache. This brings us one step closer
1134 to removing BUFF. [Ryan Bloom]
1136 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
1137 added to the stack is the last filter to be called. [Ryan Bloom]
1139 *) Apache 2.0 has been completely documented using Scandoc. The
1140 docs can be generated by running 'make docs'. [Ryan Bloom]
1142 *) Add filtered I/O to Apache. This is based on bucket brigades,
1143 Currently the buckets still use BUFF under the covers, but that
1144 should change quickly. The only currently written filter is the
1145 core filter which just calls ap_bwrite. [The Apache Group]
1147 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
1148 built with thread support. [Jeff Trawick]
1150 *) Abort configuration if --with-layout was specified and there's
1151 no layout definition file. [Ken Coar]
1153 *) Add support for '--with-port=n' option to configure. [Ken Coar]
1155 *) Add support for extension methods for the Allow response header
1156 field, and an API routine for accessing r->allowed and the
1157 list of extension methods in a unified manner. [Ken Coar]
1159 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
1160 [Rob Simonson <simo@us.ibm.com>]
1162 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
1163 APACHE_XLATE builds. [Jeff Trawick]
1165 *) A configuration file parsing problem was fixed. When the
1166 configuration file started with an IfModule/IfDefine container,
1167 only the last statement in the container would be retained.
1170 Changes with Apache 2.0a5
1172 *) Perchild is serving pages after passing them to different child
1173 processes. There are still a lot of bugs, but this does work. I
1174 have made requests against the same installation of Apache, and had
1175 different servers use different user IDs to serve the responses.
1176 This change moves to using socketpair instead of an AF_UNIX socket.
1179 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
1180 It can't seem to pass between child processes yet, but I think we
1181 are closer now than before. This moves us back to using Unix
1182 Domain Sockets. [Ryan Bloom]
1184 *) libapr functions and types renamed with apr_ prefix.
1185 #include "apr_compat.h" for 1.3.x backwards compat
1188 *) Fix problems with APR sockaddr handling on Win32. It didn't always
1189 return the right information on the local socket address.
1190 [Gregory Nicholls <gnicholls@level8.com>]
1192 *) ap_recv() on Win32: Set bytes-read to 0 on error.
1193 [Gregory Nicholls <gnicholls@level8.com>]
1195 *) Add an option to not detach from the controlling terminal without
1196 going into single process mode. This allows for much easier
1197 debugging of the process startup code. [Ryan Bloom]
1199 *) ab: don't use perror() to report the failure of an APR function.
1202 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
1203 scoreboard on graceful restarts.
1206 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
1207 An invalid ap_proc_t was passed to ap_create_process().
1210 *) Allow modules to register filters. Those filters are still
1211 never called, but this is a step in the right direction.
1212 [Ryan Bloom and Greg Stein]
1214 *) Register the mod_cgid daemon process for cleanup so that it is
1215 killed at termination if it does not die when the parent gets
1216 SIGTERM. This change is to fix occasional problems where the
1217 process stays around. Bugs in similar logic in mod_rewrite and
1218 mod_include were also fixed. [Jeff Trawick]
1220 *) Fix a bug in the time handling. Basically, we were imploding a time
1221 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
1222 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
1223 uses those two fields to adjust the time value. Because of the HTTP
1224 spec, both of those values can be zero'ed out safely. This fixes
1225 the bug correctly. [Ryan Bloom]
1227 *) Fix a couple of place in the Windows code where the wrong error
1228 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
1230 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
1232 *) Added the APR_EOL_STR macro for platform dependent differences in
1233 logfiles and other raw text (such as all APR files). Fixes logfiles
1234 not terminated with cr/lf sequences in Win32. [William Rowe]
1236 *) Move all strings functions in APR to src/lib/apr/strings and create
1237 apr_strings.h for the prototypes. [Ryan Bloom]
1239 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
1240 to repeat the syscall until we stop getting EINTR. I noticed a
1241 related problem at termination (SIGTERM) on FreeBSD when using
1242 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
1243 implementation work properly with child init. Previously, ap_lock()
1244 was essentially a no-op because all children were using different
1245 locks and thus nobody ever blocked. [Jeff Trawick]
1247 *) The htdocs/ tree has been moved out of the CVS source tree into
1248 a separate area for easier development. This has NO EFFECT on
1249 end-users or Apache installations. [Ken Coar]
1251 *) Integrate the mod_dav module for WebDAV protocol handling. This
1252 adds the dav and dav_fs modules, the SDBM library, and additional
1253 XML handling utilities. [Greg Stein]
1255 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
1258 *) Update the lib/expat-lite/ library (bring forward changes from
1259 the Apache 1.3 repository). [Greg Stein]
1261 *) If sizeof(long long) == sizeof(long), then prefer long in APR
1262 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
1264 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
1265 machines where sendfile is detected, but nobody has written ap_sendfile.
1266 [Dave Hill <ddhill@zk3.dec.com>]
1268 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
1270 *) ab would start up more connections than needed, then quit when the
1271 desired number were finished. Also fixed a logic error involving
1272 ab keepalives. [Victor J. Orlikowski]
1274 *) WinNT: Implement non-blocking pipes with timeouts to communicate
1275 with CGIs. Apache 2.0a4 had non-blocking pipes but without
1276 timeouts (i.e, if a timeout was specified, the pipe reverted to
1277 a full blocking pipe). Now the behaviour is more in line with
1278 Unix non-blocking pipes.
1281 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
1282 cache open file handles along with accept socket reuse enables
1283 Apache 2.0 to serve non-keepalive requests for static files at
1284 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
1285 and Apache 2.0 will serve almost 1200 rps on my system).
1288 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
1289 supports two config directives, mmapfile (same behavious as
1290 mod_mmap_static) and cachefile. Use the cachefile directive
1291 to cache open file handles. This directive only works on systems
1292 that have implemented the ap_sendfile API. cachefile works today
1293 on Windows NT, but has not been tested on any flavors of Unix.
1296 *) Cleanup the configuration. With the last few changes the
1297 configuration process automatically:
1298 inherits information about how to build from APR. Allowing
1299 APR to inform Apache that it should or should not use -ldl
1301 Detects which mod_cgi should be used mod_cgi or mod_cgid,
1302 based on the threading model
1304 Apache calls APR's configure process before finishing it's
1305 configuration processing, allowing for more information flow
1310 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
1311 with non-zero argument makes the socket non-blocking. BeOS and
1312 OS/2 already worked this way. [Jeff Trawick]
1314 *) ap_close() now calls ap_flush() for buffered files, so write
1315 operations work a whole lot better on buffered files.
1318 *) Fix error messages issued from MPMs which explain where to change
1319 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
1322 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
1323 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
1324 now the way that the blocking state of a pipe is manipulated.
1325 ap_block_pipe() is gone. [Jeff Trawick]
1327 *) Correct the problem where the only local host name that the IP stack
1328 can discover are 'undotted' private names. If no fully qualified
1329 domain name can be identified, the default ServerName will be set to
1330 the machine's IP address string. A warning is always provided if the
1331 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
1333 *) Repair problems with config file processing which caused segfault
1334 at init when virtual hosts were defined and which caused ServerName to
1335 be ignored when there was no valid DNS setup. [Jeff Trawick]
1337 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
1339 *) Add ap_sendfile implementation for AIX
1340 [Victor J. Orlikowski]
1342 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
1343 apr_network_io.h, and apr_thread_proc.h.
1344 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
1346 *) Bring the allocation and pool debugging code back into a working
1347 state. This will need to be tested as so far it's only been used on
1350 *) Change configuration command setup to be properly typesafe when in
1351 maintainer mode. Note that this requires a compiler that can initialise
1352 unions. [Ben Laurie]
1354 *) Turn on buffering for config file reads. Part of this was to
1355 repair buffered I/O support in Unix and implement buffered
1356 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
1358 *) Win32: Fix problem where UTC offset was not being set correctly
1359 in the access log. Problem reported on news group by Jerry Baker.
1362 *) Fix segfault when reporting this type of syntax error:
1363 "</container> without matching <container> section", where
1364 container is VirtualHost or Directory or whatever.
1367 *) Prevent the source code for CGIs from being revealed when using
1368 mod_vhost_alias and the CGI directory is under the document root
1369 and a user makes a request like http://www.example.com//cgi-bin/cgi
1370 as reported in <news:960999105.344321@ernani.logica.co.uk>
1373 *) Add support for the new Beos NetwOrking Environment (BONE)
1376 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
1377 final input char is incomplete; ap_bwrite_xlate() now handles
1378 incomplete final input chars. [Jeff Trawick]
1380 *) Yet another update to saferead/halfduplex stuff -- need to ensure
1381 that a bhalfduplex call occurs before logging or else DNS and
1382 such can delay the last packet of the response. [Dean Gaudet]
1384 *) Some syscall reduction in APR on unix -- don't seek when setting
1385 up an mmap; and don't fcntl() more than once per socket.
1388 *) When mod_cgid is started as root, the cgi daemon now switches
1389 to the configured User/Group (like other httpd processes)
1390 instead of continuing as root. [Jeff Trawick]
1392 *) The prefork MPM now uses an APR lock for the accept() mutex.
1393 It has not been getting a lock at all recently. httpd -V now
1394 displays APR's selection of the lock mechanism instead of the
1395 symbols previously respected by prefork. [Jeff Trawick]
1397 *) Change the mmap() feature test to check only for existence.
1398 The previous check required features not used by Apache.
1401 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
1402 sometimes mangled. The len parm to accept() was not
1403 initialized, leading sometimes to an endless loop of failed
1404 accept() calls on OS/390 and anywhere else that failed the call
1405 if the len was negative. Use <sys/un.h> for struct sockaddr_un
1406 instead of declaring it ourselves to fix a compilation problem
1407 on Solaris. [Jeff Trawick]
1409 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
1411 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
1413 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
1415 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
1416 initialization if ALLOC_DEBUG is defined; no known symptom
1417 otherwise. [Jeff Trawick]
1419 *) Fix typo in configure script when checking for mod_so. bash
1420 doesn't seem to have a problem but /bin/sh on Solaris does.
1421 Symptom: "./configure: test: unknown operator =="
1424 *) Rebind the Win32 NT and 9x services control into the MPM.
1425 All console, WinNT SCM and Win9x pseudo-service control code is
1426 now wrapped within the WinNT MPM.
1429 *) Make a copy of getenv("PATH") before storing for later use. Some
1430 getenv() implementations use the same storage for successive calls.
1431 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
1433 *) Server Tokens work in 2.0 again. This also propogates the change
1434 to allow just the product name in the server string using
1438 Changes with Apache 2.0a4
1440 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
1441 won't need to call it. [Greg Ames, Jeff Trawick]
1443 *) Move pre_config hook call to between configuration read and config
1444 tree walk. This allows all modules to implement pre_config hooks
1445 and know that they will be called at an appropriate time.
1448 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
1451 *) Add pre-config hooks back to all modules.
1454 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
1455 ContentDigest enabled and we can't/don't mmap the file.
1458 *) We now report the correct line number for syntax errors in config
1459 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
1461 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
1462 related bugs, and changed shmem/locking to use apr API. Shared-mem
1463 is currently disabled, however, because of problems with graceful
1464 restarts. [Ronald Tschalär]
1466 *) Fix corruption of IFS variable in --with-module= handling.
1467 Depending on the user's shell or customization thereof, there
1468 would be errors generating ap_config_auto.h later in the configure
1469 procedure. [Jeff Trawick]
1471 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
1472 isn't used (as in 1.3), except that on Unix it is now logged via
1473 ap_log_rerror() instead of by the child having STDERR_FILENO refer
1474 to the error log. [Greg Ames, Jeff Trawick]
1476 *) Add '-D' argument processing for run time configuration defines.
1479 *) Organize http_main.c as independent code, such that no code or
1480 global data is exported from it. WIN32 will dynamically link it
1481 to the server core, so this will prevent mutual dependency.
1484 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
1485 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
1488 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
1489 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
1491 *) Add mod_charset_lite for configuring character set translation.
1494 *) Add '-n' option to htpasswd to make it print its user:pw record
1495 on stdout rather than having to frob a text file. [Ken Coar]
1497 *) Fix saferead. Basically, we flush the output buffer if a read on the
1501 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
1502 a conversion is single-byte only. [Jeff Trawick]
1504 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
1505 the BeOS 5.0 documentation says that shutdown doesn't work yet.
1508 *) Fix some minor errors where pid was being manipulated as an int
1509 instead of the portable pid_t. [Roy Fielding]
1511 *) Fix some error log prints that were printing the pointer to a
1512 structure rather than the pid within the structure.
1513 [Jeff Trawick, Roy Fielding]
1515 *) ab: Fix a command-line processing bug; track bad headers in
1516 err_response; support reading headers up to 2K.
1517 [Ask Bjoern Hansen <ask@valueclick.com>]
1519 *) Fix ap_resolve_env() so that it handles new function added in a prior
1520 alpha (see "Added the capability to do ${ENVVAR} constructs in the
1521 config file.") as well as the constructs used by mod_rewrite.
1522 [Paul Reder <rederpj@raleigh.ibm.com>]
1524 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
1526 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
1527 APR to perform translation, instead of accessing the hard-coded tables
1528 in 1.3's ebcdic.c. [Jeff Trawick]
1530 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
1533 *) Add the ability to hook into the config file reading phase. Basically
1534 if a directive is specified EXEC_ON_READ, then when that directive is
1535 read from the config file, the assocaited function is executed. This
1536 should only be used for those directives that must muck with HOW the
1537 server INTERPRETS the config. This should not be used for directives
1538 that re-order or replace items in the config tree. Those changes should
1539 be made in the pre-config step.
1542 *) Add mod_example to the build system.
1545 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
1546 byte character sets. [Jeff Trawick]
1548 *) Pick up various EBCDIC fixes from 1.3 (from Martin
1549 Kraemer and Oliver Reh originally according to the change log).
1552 *) Fix a couple of problems in RFC1413 support (controlled by the
1553 IdentityCheck directive). Apache did not build the request string
1554 properly and more importantly Apache would loop forever if the
1555 would-be ident server dropped the connection before sending a
1556 properly terminated response. [Jeff Trawick]
1558 *) apxs works in 2.0.
1561 *) Reliable piped logs work in 2.0.
1564 *) Introduce a hash table implementation into APR to be used for
1565 replacing tables and other random data structures in Apache.
1568 *) Add some more error reporting to htpasswd in the case of problems
1569 generating or accessing the temporary file. Also, pass in a
1570 buffer if the implementation knows how to use it (i.e., if L_tmpnam
1571 is defined). [Ken Coar]
1573 *) Configure creates config.nice now containing your configure
1574 options. Syntax: ./config.nice [--more-options]
1577 *) Fix various return code problems in APR on Win32. For most of
1578 these, APR was returning APR_EEXIST instead of GetLastError()/
1579 WSAGetLastError(). [Jeff Trawick]
1581 *) Make piped logs work again in version 2.0
1584 *) Add VPATH support to UNIX build system of Apache and APR.
1587 *) Fix ap_tokenize_to_argv to respect the const arguments that are
1591 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
1592 Patch submitted to author.
1595 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
1596 /sbin in PATH on FreeBSD (all submitted to rse previously)
1599 *) Fix building Pthread-based MPMs on OpenBSD
1600 [Sascha Schumann] PR#26
1602 *) Fix ap_readdir() problem on systems where d_name[] field in
1603 struct dirent is declared with only one byte. (This problem only
1604 affected multithreaded builds.) This caused a segfault during
1605 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
1606 least). [Jeff Trawick]
1608 *) Fix some make-portability problems on at least Tru64, Irix
1610 [Sascha Schumann] PR#18, PR#39
1612 *) Add ap_sigwait() to support old-style sigwait() on systems
1613 like OS/390 and UnixWare.
1616 *) Add POSIX-thread flags for more platforms.
1619 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
1620 (on Unix, at least) to handle resolver errors. Fix a bug in
1621 the definition of APR_ENOMEM so that ap_strerror() can spit
1622 out the correct error message for it.
1625 Changes with Apache 2.0a3
1627 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
1630 *) API: *HOOK* macros now have an AP_ prefix
1633 *) Win32: Eliminate redundant calls to initialize winsock.
1634 [Tim Costello <timcostello@ozemail.com.au>]
1636 *) Fix bugs initializing ungetchar for pipes.
1637 [Chia-liang Kao <clkao@CirX.ORG>]
1639 *) The ab program in the src/support directory is now portable using
1643 *) Support directory is being compiled when the server is built
1646 *) The configure option --with-program-name has been added to allow
1647 developers to rename the executable at configure time. This also
1648 changes the name of the config files to match the executable's name.
1651 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
1652 containing version numbers. [Martin Pool]
1654 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
1655 Unix; access_log and error_log now created with these perms; non-
1656 Unix is unaffected [Jeff Trawick]
1658 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
1659 Replaced more magic numbers with MD5_DIGESTSIZE.
1660 [William Rowe, Roy Fielding]
1662 *) Win32: Get mod_auth_digest compiling and added to the Windows
1663 build environment. Not tested and I'd be suprised if it
1664 actually works. [Bill Stoddard]
1666 *) Revamp the Win32 make environment. Makefiles have been removed and
1667 Apache.dsw created to bring together all the pieces. Create new file
1668 os/win32/BaseAddr.ref to define module base addresses (to prevent
1669 dll relocation at start-up).
1670 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
1672 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
1673 of the \015, \012, and \015\012 constants with macros.
1674 [Greg Ames <gregames@us.ibm.com>]
1676 *) Add ap_xlate_open() et al for translation of text between different
1677 character sets. The initial implementation requires iconv().
1680 *) More FAQs and answers from comp.infosystems.www.servers.unix.
1681 [Joshua Slive <slive@finance.commerce.ubc.ca>]
1683 *) CGI output is being timed out now.
1686 *) Fix the problem with dieing quietly. dupfile now takes a pool which
1687 is used by the new apr file. There is no reason to create a new file
1688 with the same lifetime as the original file.
1691 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
1692 module base addresses. This will help shooting seg faults
1693 in the field. [William Rowe <wrowe@lnd.com>]
1695 *) Update Apache on Windows documentation. Add new document
1696 describing how to compile Apache on Windows.
1697 [William Rowe <wrowe@lnd.com>]
1699 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
1700 microseconds instead of seconds. Some storage leaks and other
1701 minor bugs in related code were fixed. [Jeff Trawick]
1703 *) Win32: First cut at getting mod_isapi working under 2.0
1704 [William Rowe <wrowe@lnd.com>]
1706 *) First stab at getting mod_auth_digest working under 2.0
1707 quick change summary:
1708 - moved the random byte generation (ap_generate_random_bytes) into APR
1709 - now uses ap_time_t
1710 - compiles and runs on linux
1712 [Brian Martin <bmartin@penguincomputing.com>]
1714 *) Win32: Move the space stripping of physical service names
1715 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
1716 unresolved symbol. Add dependency checking to the
1717 CreateService call to ensure TCPIP and AFP (winsock) is started
1719 [William Rowe <wrowe@lnd.com>]
1721 *) Win32: Add code to perform latebinding on functions that may
1722 not exist on all levels of Windows where Apache runs. This
1723 is needed to allow Apache to start-up on Win95/98. All calls
1724 to non portable functions should be protected with
1725 ap_oslevel checks to prevent runtime segfaults.
1726 [William Rowe <wrowe@lnd.com>]
1728 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
1730 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
1732 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
1733 This addresses PR 1623. Still need to address timing out runaway
1734 CGI scripts. [Bill Stoddard]
1736 *) Win32: Make ap_stat Windows 95/98 friendly
1737 [William Rowe <wrowe@lnd.com>]
1739 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
1740 always fail. Need to initialise the dwOSVersionInfoSize member of the
1741 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
1744 The patch also enhances ap_get_oslevel (and the associated enum) to
1745 handle selected service packs for NT4, and adds recognition for
1746 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
1747 we can use ReadFileScatter and WriteFileGather in readwrite.c.
1748 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
1750 *) Get mod_rewrite building and running, and mod_status building for Win NT
1751 [Allan Edwards <ake@raleigh.ibm.com>]
1753 *) Patch to port mod_auth_db to the 2.0 api and also to support
1754 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
1755 2.7.7. It should work with version 1 as well but I haven't tested it.
1756 [Brian Martin <bmartin@penguincomputing.com>]
1758 *) Get APR DSO code working under Windows. Includes cross platform
1760 [Tim.Costello@BTFinancialgroup.com]
1762 *) Fix some of the Windows APR time functions.
1765 *) FAQ changes related to tidying up historical documents on the web site.
1766 [Joshua Slive <slive@finance.commerce.ubc.ca>]
1768 *) Move Windows DSO code into APR.
1771 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
1772 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
1773 at build time. At this point, the server will not compile on Windows because
1774 of the recent DSO commits. Fixing those next.
1775 [Bill Rowe & Bill Stoddard]
1777 *) Added error checking for file I/O APR routines.
1778 [Jon Travis <jtravis@covalent.net>]
1780 *) APR: Don't use the values of resolver error codes for the
1781 corresponding APR error codes. On Unix and Win32, return the
1782 proper APR error code after a resolver error. [Jeff Trawick]
1784 Changes with Apache 2.0a2
1786 *) Renamed the executable back to httpd on all platforms other
1790 *) Allow BeOS to survive restarts, log properly and a few
1791 small things it had problems with due to the way it setup
1792 users and groups. [David Reid]
1794 *) Get mod_rewrite working with APR locks
1795 [Paul Reder <rederpj@raleigh.ibm.com>]
1797 *) Actually remove the sempahore when the lock cleanup routine
1798 is called on BeOS. [David Reid]
1800 *) Clear hook registrations between reads of the config file.
1801 When DSOs are unloaded and re-loaded the old hook pointers may
1802 no longer be valid. This fix eliminates potential segfaults.
1803 [Allan Edwards <ake@raleigh.ibm.com>]
1805 *) Fix a problem with Sigfunc not being defined or bypassed
1806 if sigaction() wasn't found. [Jim Jagielski]
1808 *) Fix the locking mechanism on BSD variants. They now use fcntl
1809 locks. This allows the server to start and serve pages.
1812 *) First cut at getting the Win32 installer to work
1813 [William Rowe <wrowe@lnd.com>]
1815 *) Get htpasswd compiling under Windows
1816 [William Rowe <wrowe@lnd.com>]
1818 *) Change the log message for a bind() failure to show the
1819 interface and port number. [Jeff Trawick]
1821 *) Import the documentation from 1.3.12 and bring parts of it
1822 up-to-date with respect to the changes that have occurred
1826 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
1827 now logged correctly on BeOS.
1830 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
1831 Makefile.win includes the same user interface as the old
1833 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
1835 *) Win32 exec now uses COMSPEC environment string for command
1836 shell path resolution.
1837 [William Rowe <wrowe@lnd.com>] PR#3715
1839 *) Win32: ap_connect() was not returning correct error condition
1841 [Allen Prescott <allen@clanprescott.com>]
1843 *) Win32: ap_open() was broken on Win9x because an NT-specific
1844 flag was passed to CreateFile. ap_puts() added an unnecessary
1846 [Jeff Trawick <trawick@us.ibm.com>]
1848 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
1849 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
1850 confusing ee/et name and made all extensions language/dialect
1851 rather than country reflecting. Changed example files to
1852 explicit reflect the ISO charset and added a few common
1853 ones to the example config [dirkx]
1855 *) Extend external module capability. To use this, you call
1856 configure with --with-module=path/to/mod1,path/to/mod2,etc.
1859 *) Backported the various "default charset" fixes from 1.3.12,
1860 including the AddDefaultCharset directive. [Jim Jagielski]
1862 *) Added the capability to do ${ENVVAR} constructs in the
1863 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
1864 it does this on a line by line basis; i.e. if the envvar
1865 expands to something with spaces you have to protect it
1866 by adding quotes around it (Unless of course you expect it
1867 to contains more than one argument. Alternatively you
1868 can compile it on a per token basis; which is what people
1869 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
1870 hampers fancier hacks.
1871 [Dirk-Willem van Gulik]
1873 *) Changed the 'ErrorDocument' syntax in that it NO longer
1874 supports the asymetric
1876 ErrorDocument 301 "Some message
1878 Note the opening " quote, without a closing quote. It now
1879 has either the following syntaxes
1881 ErrorDocument XXX /local/uri
1882 ErrorDocument XXX http://valid/url
1883 ErrorDocument XXX "Some Message"
1885 The recognition heuristic is: if it has a space it
1886 is a message. If it has no spaces and starts with a /
1887 or is a valid URL then treat it that way. Otherwise it
1888 is assumed to be a message.
1890 This breaks backward compatibility but makes live a hell
1891 of a lot easier for GUI's and config file parsers.
1892 [Dirk-Willem van Gulik]
1894 *) Changed 'CacheNegotiatedDocs' from its present/not-present
1895 syntax into a 'on' or 'off' syntax. As it currently is the
1896 only non nesting token which uses NO_ARGS and thus is an
1897 absolute pain for any config interface automation. This
1898 breaks backward compatibility. [Dirk-Willem van Gulik]
1900 *) Add ability to add external modules to the build process. This is
1901 done with --with-module=/path/to/module. Modules can only be added
1902 as static modules at this point.
1905 Changes with Apache 2.0a1
1907 *) Fix FreeBSD 3.3 core dump.
1908 Basically, ap_initialize() needs to get called before
1909 create_process(), since create_process() passes op_on structure
1910 to semop() to get a lock, but op_on isn't initialized until
1911 ap_initialize() calls setup_lock(). Here is a slight
1912 rearrangement to main() which calls ap_initialize() earlier...
1913 [Jeff Trawick <trawick@us.ibm.com>]
1915 *) Enable Apache to use sendfile/TransmitFile API
1916 [Bill Stoddard, David Reid, Paul Reder]
1918 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
1922 *) Make file I/O and network I/O writev/sendv APIs consistent.
1923 Eliminate use of ap_iovec_t and use Posix struct iovec.
1924 Use seperate variable on ap_writev to set the number of iovecs
1925 passed in and number of bytes written.
1928 *) Adapt file iol to use APR functions. Replaced ap_open_file()
1929 with ap_create_file_iol(). ap_create_file_iol() requires that
1930 the file be opened prior to the call using ap_open().
1933 *) Port mod_include and mod_cgi to 2.0
1934 [Paul Reder, Bill Stoddard]
1936 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
1937 bytes_read/bytes_written is always valid (never -1). Plus
1938 some fixes to buff.c to correct problems introduced by the
1939 errno => ap_status_t changes a while back. Plus a fix to
1940 chunked encoding introduced right at the beginning of 2.0.
1943 *) Revamped UNIX build system to use autoconf and libtool.
1944 [Manoj Kasichainula, Sascha Schumann]
1946 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
1948 *) More rigorous checking of Host: headers to fix security problems
1949 with mass name-based virtual hosting (whether using mod_rewrite
1950 or mod_vhost_alias).
1951 [Ben Hyde, Tony Finch]
1953 *) Add back support for UseCanonicalName in <Directory> containers.
1954 [Manoj Kasichainula]
1956 *) Added APLOG_STARTUP log type. This allows us to write an error
1957 message without any of the date and time information. As a part
1958 of this change, I also removed all of the calls to fprintf(stderr
1959 and replaced them with calls to ap_log_error using APLOG_STARTUP
1960 writing to stderr is no longer portable, because we don't direct
1961 stderr to the error log on all platforms.
1964 *) Convert error logging functions to take errno as an argument.
1965 This makes our error logs more portable, because some Windows API's
1966 don't set errno. This change allows us to still output a valid
1967 message on all of our platforms.
1970 *) mod_mime_magic runs in 2.0-dev now.
1971 [Paul Reder <rederpj@raleigh.ibm.com>]
1973 *) sendfile has been added to APR.
1974 [John Zedlewski <zedlwski@Princeton.EDU>]
1976 *) buff.c has been converted to no longer use errno.
1977 [Manoj Kasichainula]
1979 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
1980 interface adaption to APR functions did it. [Martin Kraemer]
1982 *) Support DSOs properly on 32-bit HP-UX 11.0
1983 [Dilip Khandekar <dilip@cup.hp.com>]
1985 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
1986 [Ralf S. Engelschall]
1988 *) Cleaned APR build environment integration and bootstrap APR
1989 automatically for developers from src/Configure.
1990 [Ralf S. Engelschall]
1992 *) Fixed building of src/support/htpasswd.c
1993 [Ralf S. Engelschall]
1995 *) When generating the Location: header, mod_speling forgot
1996 to escape the spelling-fixed uri. (Forw-Port from 1.3)
1999 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
2001 *) Change all pools to APR contexts. This is the first step to
2002 incorporating APR into Apache. [Ryan Bloom]
2004 *) Move "handler not found" warning message to below the check
2005 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
2006 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
2008 *) Support line-continuation feature in config.option file and
2009 allow the loading of multiple option sections at once via
2010 ``--with-option=<section1>,<section2>,...''
2011 [Ralf S. Engelschall]
2013 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
2015 Changes with Apache MPM
2017 *) Use asynchronous AcceptEx() and a completion port to accept and
2018 dispatch connections to threads in Windows NT/2000.
2021 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
2024 *) Implement the APACI --with-option facility
2025 (per default used the config.option file).
2026 [Ralf S. Engelschall]
2028 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
2030 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
2031 Replace pre_connection module call with a register_hook call and
2032 implement pre_connection as a hook. The intent is that these hooks will
2033 be extended to allow Apache to be multi-protocol, and also to allow the
2034 calling order to be specified on a per-hook/per-module basis.
2037 *) Implement mpm_* methods as "modules". Each method gets its own
2038 subdir in src/modules (eg: src/modules/prefork). Selection
2039 of method uses Rule MPM_METHOD. [Jim Jagielski]
2041 *) Port the hybrid server from the apache-apr repository as
2042 mpm_mpmt_pthread. [Manoj Kasichainula]
2044 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
2045 amongst the unix MPMs.
2047 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
2048 signal handling for the new world order. [Dean Gaudet]
2050 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
2051 of alloc.c for now. [Dean Gaudet]
2053 *) Handle partial large writes correctly. [Ben Laurie]
2055 *) Eliminate conn_rec's pointer to server. All it knows is the base server
2056 based on IP/port. [Ben Laurie]
2058 *) Port a bunch of modules to the new module structure.
2059 ["Michael H. Voase" <mvoase@midcoast.com.au>]
2061 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
2063 *) Basic restructuring to introduce the MPM concept; includes various
2064 changes to the module API... better described by
2065 docs/initial_blurb.txt. [Dean Gaudet]
2067 Changes with Apache pthreads
2069 *) New buff option added: BO_TIMEOUT. It describes the timeout for
2070 buff operations (generally over a network).
2071 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
2073 *) Created http_accept abstraction. Added 4 new functions (not exported):
2074 init_accept(), begin_accepting_requests(), get_request(),
2075 stop_accepting_requests() [Bill Stoddard]
2077 *) Fix to ap_rprintf call that allows mod_info to work properly.
2078 [James Morris <jmorris@intercode.com.au>]
2080 *) user and ap_auth_type fields were moved from connection_rec to
2081 request_rec. [Ryan Bloom]
2083 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
2084 needed in a threaded server.
2086 *) Initial pthread implementation from from Dean's apache-nspr code.
2087 [Bill Stoddard, Ryan Bloom]
2090 Changes with Apache 1.3.9
2092 *) Remove bogus error message when a redirect doesn't set Location.
2093 Instead, use an empty string to avoid coredump if the error message
2094 was supposed to include a location. [Roy Fielding]
2096 *) Don't allow configure to include mod_auth_digest unless it is
2097 explicitly requested, even if the user asked for all modules.
2100 *) Translate module names to dll names for OS/2 so that they are no more
2101 than 8 characters long and have an extension of "dll" instead of "so".
2104 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
2105 Fix test-compile check to check for randbyte instead of trand32.
2106 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
2107 and tweak to make Amaya happier. [Ronald Tschalär]
2109 *) Ensure that the installed expat include files are world readable,
2110 just like the other header files. [Martin Kraemer]
2112 *) Fixed generated AddModule adjustments in APACI's `configure' script
2113 in order to allow (new) modules like mod_vhost_alias to be handled
2114 correctly (which was touched by the adjustments for mod_alias).
2115 [Ralf S. Engelschall]
2117 *) For binary builds, add -R flag to apachectl to work around the lack of
2118 an absolute path to the ./libexec directory where the libhttp.ep file
2119 is needed for SHARED_CORE architectures. [Randy Terbush]
2121 *) WIN32: Create the CGI script process as DETACHED. This may solve the
2122 problem observed by some Win95/98 users where they get CGI script
2123 output sent to the console. [Bill Stoddard]
2125 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
2126 routines are now called ap_base64* and are 'plain' (i.e., no
2127 pool access or anything clever). Inside util.c the routines acting
2128 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
2129 The oddly named ap_uuencode(), ap_uudecode() are kept around for
2130 now but deprecated. [dirkx]
2132 *) Clean up the base64 and SHA1 additions and make sure they are
2133 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
2134 files. [Roy Fielding]
2136 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
2137 checking. Allow compiling on VS 6.0. [Randy Terbush]
2139 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
2141 *) Use TestCompile to search for the truerand library (rather than blindly
2142 assuming its existence). If it is not found, complain (but do not
2143 exit - yet). [Martin Kraemer]
2145 *) We forgot to add the new exported function names to
2146 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
2148 *) Add description of -T command-line option to usage().
2149 [Ralf S. Engelschall]
2151 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
2152 searched only AFTER libap has been searched, because libap needs
2153 some symbols from libos. [Martin Kraemer]
2155 *) Fix conflict with original mod_digest related to the symbol of the
2156 module dispatch list (which has to be unique for DSO and follow the
2157 usual conventions for the installation procedure).
2158 [Ralf S. Engelschall]
2160 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
2161 for other platforms as well. [Martin Kraemer]
2163 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
2164 types by AP_LONG and replace reference to renamed variable 'ubuf'
2165 by 'buffer'. [Martin Kraemer]
2167 Changes with Apache 1.3.8 [not released]
2169 *) Flush the output buffer immediately after sending an error or redirect
2170 response, since the result may be needed by the client to abort a
2171 long data transfer or restart a series of pipelined requests.
2172 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
2174 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
2175 [Ian Turner <iant@sequent.com>] PR#4735
2177 *) Local struct mmap in http_core.c conflicted with system structure
2178 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
2180 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
2181 [Ronald Tschalär <ronald@innovation.ch>]
2183 *) Fix a memory leak where the module counts were getting messed
2184 up across restarts. [David Harris <dharris@drh.net>]
2186 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
2187 properly in mod_access.
2188 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
2190 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
2191 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
2193 *) PORT: Support for compaq/tandem/com.
2194 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
2196 *) Added SHA1 password encryption support to easy migration from
2197 Netscape servers. See support/SHA1 for more information.
2198 Caused the separation of ap_md5.c into md5, sha1 and a general
2199 ap_checkpass.c with just a validate_passwd routine. Added a
2200 couple of flags to support/htpasswd. Some reuse of the to64()
2201 function; hence renamed to ap_to64().
2202 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
2204 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
2205 with ASCII/EBCDIC conversions in "ident" query.
2206 [David McCreedy <McCreedy@us.ibm.com>]
2208 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
2209 Change "Power Macintosh" to Power* so if uname prints "Power Book"
2210 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
2212 *) Fix SIGSEGV on some systems because the Vary fix below included
2213 a call to table_do with a variable argument list that was not
2214 NULL terminated. Replaced with better implementation. [Roy Fielding]
2216 Changes with Apache 1.3.7 [not released]
2218 *) The "Vary" response header field is now sanitised right before
2219 the header is sent back to the client. Multiple "Vary" fields
2220 are combined, and duplicate tokens (e.g., "Vary: host, host" or
2221 "Vary: host, negotiate, host, accept-language") are reduced to
2222 single instances. This is a better solution than the force-no-vary
2223 one (which is still valid for clients that can't cope with Vary
2224 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
2226 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
2228 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
2229 least on Linux and FreeBSD for now.
2232 *) Win32: More apache -k restart work. Restarts are now honored
2233 immediately and connections in the listen queue are -not- lost.
2234 This is made possible by the use of the WSADuplicateSocket()
2235 call. The listeners are opened in the parent, duplicated, then
2236 the duplicates are passed to the child. The original listen sockets
2237 are not closed by the parent across a restart, thus the listen queue
2239 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2241 *) Fix handling of case when a client has sent "Expect: 100-continue"
2242 and we are going to respond with an error, but get stuck waiting to
2243 discard the body in the pointless hope of preserving the connection.
2244 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
2246 *) Fix 'configure' to work correctly with SysV-based versions of
2247 'tr' (consistent with Configure's use as well). [Jim Jagielski]
2249 *) apxs: Add "-S var=val" option which allows for override of CFG_*
2250 built-in values. Add "-e" option which works like -i but doesn't
2251 install the DSO; useful for editing httpd.conf with apxs. Fix
2252 editing code so that multiple invocations of apxs -a will not
2253 create duplicate LoadModule/AddModule entries; apxs can now be
2254 used to re- enable/disable a module. [Wilfredo Sanchez]
2256 *) Win32: Update the server to use Winsock 2. Specifically, link with
2257 ws2_32.lib rather than wsock32.lib. This gives us access to
2258 WSADuplcateSocket() in addition to some other enhanced comm APIs.
2259 Win 95 users may need to update their TCP/IP stack to pick up
2260 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
2261 [Bill Stoddard stoddard@raleigh.ibm.com]
2263 *) Win32: Redirect CGI script stderr (script debug info) into the
2264 error.log when CGI scripts fail. This makes Apache on Win32
2265 behave more like Unix.
2266 [Bill Stoddard stoddard@raleigh.ibm.com]
2268 *) Fixed `httpd' usage display: -D was missing.
2269 [Ralf S. Engelschall] PR#4614
2271 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
2272 [Ralf S. Engelschall] PR#4561, PR#4562
2274 *) OS/2: Fix problem with accept lock semaphores where server would die with
2275 "OS2SEM: Error 105 getting accept lock. Exiting!"
2276 [Brian Havard] PR#4505
2278 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
2279 [Randy Terbush <randy@covalent.net>]
2281 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
2282 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
2284 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
2285 command potentially _is_ GCC. [Ralf S. Engelschall]
2287 *) Fix apxs build issues on AIX
2288 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
2290 *) DocumentRoot Checking: Under previous versions, when Apache
2291 first started up, it used to do a stat of each DocumentRoot to
2292 see if it existed and was a directory. If not, then an error
2293 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
2294 does not exist, you will get error messages in error_log. If
2295 the '-t' command line option is used (to check the configuration)
2296 the check of DocumentRoot IS performed. An additional command
2297 line option, '-T', has been added if you want to avoid the
2298 DocumentRoot check even when checking the configuration.
2301 *) Win32: The query switch "apache -S" didn't exit after showing the
2302 vhost settings. That was inconsistent with the other query functions.
2303 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
2305 *) Win32: Changed behaviour of apache -k restart.
2306 Previously, the server would drain all connections in the stack's
2307 listen queue before honoring the restart. On a busy server, this
2308 could take hours. Now, a restart is honored almost immediately.
2309 All connections in Apache's queues are handled but connections in
2310 the stack's listen queue are discarded. Restart triggered by
2311 MaxRequestPerChild is unchanged.
2312 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2314 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
2315 the accept loop. Good for a 5% performance boost. Cleaned up
2316 parent/child process management code.
2317 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2319 *) Added ceiling on file size for memory mapped files.
2320 [John Giannandrea <jg@meer.net>] PR#4122
2322 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
2323 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
2324 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
2326 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
2327 use this at least for Expat. [Ralf S. Engelschall]
2329 *) Allow .module files to specify libraries with Lib:.
2332 *) Allow SetEnvIf[NoCase] to test environment variables as well
2333 as header fields and request attributes. [Ken Coar]
2335 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
2336 content-types are "text/html;parameters". PR#4524 [Ken Coar]
2338 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
2339 never accepted into any standard, and it opens up certain DoS
2340 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
2342 *) TestCompile updated. We can now run programs and output the
2343 results during the Configure process. [ Jim Jagielski]
2345 *) The source is now quad (long long) aware as needed. Specifically,
2346 the Configure process determines the correct size of off_t and
2347 *void. When the OS/platform/compiler supports quads, ap_snprintf()
2348 provides for the 'q' format qualifier (if quads are not available,
2349 'q' is silently "demoted" to long). [Jim Jagielski]
2351 *) When the username or password fed to htpasswd is too long, include the
2352 size limit in the error message. Also report illegal characters
2353 (currently only ':') in the username. Add the size restrictions
2354 to the man page. [Ken Coar]
2356 *) Fixed the configure --without-support option so it doesn't result in
2357 an infinite loop. [Marc Slemko]
2359 *) Piped error logs could cause a segfault if an error occured
2360 during configuration after a restart.
2361 [Aidan Cully <aidan@panix.com>] PR#4456
2363 *) If a "Location" field was stored in r->err_headers_out rather
2364 than r->headers_out, redirect processing wouldn't find it and
2365 the server would core dump on ap_escape_html(NULL). Check both
2366 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
2367 if Location isn't set. [Doug MacEachern, Ken Coar]
2369 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
2370 of the Expat 1.0.2 distribution. [Greg Stein]
2372 *) Replace regexec() calls with calls to a new API stub function
2373 ap_regexec(). This solves problems with DSO modules which use the regex
2374 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
2376 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
2377 environment variables can be set according to the protocol version
2378 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]

2395 *) Support for server-parsed and multiview-determined ReadmeName and
2396 HeaderName files in mod_autoindex. Removed the restriction on
2397 "/"s in ReadmeName and HeaderName directives since the *sub_req*
2398 routines will deal with the access issues. (It's now possible to

2435 being newer than Configuration so that it is less likely to fail
2436 when using APACI and shadow sources. [Wilfredo Sanchez]
2438 *) PORT: Add initial support for Mac OS (versions 10.0 and
2439 greater). Use Mac OS X Server layout for now. Clean up dyld code
2440 in unix/os.c, and don't install the dyld error handlers, which
2441 are no longer needed in Mac OS. [Wilfredo Sanchez]
2443 *) Rename Rhapsody layout to "Mac OS X Server". Change install
2444 locations to appropriate ones for user-built (as opposed to
2445 system) installs. [Wilfredo Sanchez]
2447 *) Modify mod_autoindex's handling of AddDescription so that the
2448 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
2450 *) Add functionality to the install-bindist.sh script created by
2451 binbuild.sh to use tar when copying distribution files to the
2452 serverroot. This allows upgrading an existing installation
2453 without nesting the new distribution in the old.
2455 install-bindist.sh now detects the local perl5 path to install
2456 apxs and dbmmanage with proper path to perl interpreter.
2458 Add an install-binsupport target which copies the source files
2459 for apxs and dbmmanage to bindist to allow these scripts to
2460 be properly installed relative to the destination serverroot.

2577 htpasswd utility was limiting passwords to only 8 characters.
2580 *) EBCDIC platforms: David submitted patches for two bugs in the
2581 MD5 digest port for EBCDIC machines:
2582 a) the htdigest utility overwrote the old contents of the digest file
2583 b) the Content-MD5 header value (ContentDigest directive) was wrong
2584 when the returned file was not converted from EBCDIC, but was a
2585 binary (e.g., image file) in the first place.
2586 [David McCreedy <mccreedy@us.ibm.com>]
2588 *) support/htpasswd now permits the password to be specified on the

2627 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
2628 a roughly 5 fold speed up. [Brian Havard]
2630 *) proxy ftp: instead of using the hardwired string "text/plain" as
2631 a fallback type for files served by the ftp proxy, use the
2632 ap_default_type() function to determine the configured type.
2633 This allows for special configurations like
2634 <Directory proxy:ftp://some.host>
2635 DefaultType gargle/blurb
2637 Additionally, add the Content-Encoding: header to FTP proxy replies
2638 when the encoding is defined (by the AddEncoding directive).
2639 Because it was missing, it was almost impossible to browse compressed
2640 files using the FTP proxy (works now perfectly in Communicator).
2641 The ftp proxy now also returns the Date: and Server: header lines (if not
2642 much else... This code is "somewhat" broken) like normal requests do.
2645 *) Be more smart in APACI's configure script when determining the UID/GID
2646 for User/Group directives and use the determined UID/GID to initialize
2647 the permissions on the proxycachedir.
2648 [Dirk-Willem van Gulik, Ralf S. Engelschall]
2650 *) Changed the forking-prior-to-cleanup in the proxy module to first

2685 *) Added PassAllEnv; makes server's entire environment available
2686 to CGIs and SSIs executed within directive's scope. [Ken Coar]
2688 *) ap_uuencode() always added two trailing '='s and encoding of
2689 8 bit characters on a machine with signed char may produced
2690 incorrect results. Additionally ap_uuencode() should now
2691 work correctly on EBCDIC platforms.
2692 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
2694 *) WIN32: Binary installer now runs the configuration DLL before
2695 the reboot prompt (which is only given if MSVCRT.DLL system
2696 DLL is new or updated). This should avoid the configuration
2697 directory being empty after installation. [Paul Sutton]

2721 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
2722 for 8-bit safeness. [Dean Gaudet]
2724 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
2725 because SPARCs have a small machine-specific maximum size for the Global
2726 Offset Table which is often exceeded when compiling one of the larger
2727 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
2729 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the

2756 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
2759 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
2760 to make platform installations easier. [Wilfredo Sanchez]
2762 *) In configure, do not append the target name to the directory path if
2763 the path already contains "apache". [Ralf S. Engelschall]
2765 *) SIGPIPE is now ignored by the server core. The request write routines
2766 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
2767 correctly check for output errors and mark the connection as aborted.
2768 Replaced many direct (unchecked) calls to ap_b* routines with the
2769 analogous ap_r* calls. [Roy Fielding]
2771 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
2772 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
2773 Furthermore map lookups for non-existent keys are now cached as well.
2774 Additionally "txt" maps are now parsed with simple string functions
2775 instead of using ap_pregcomp(). As a side effect a bug that prevented
2776 the usage of keys containing the "," character was fixed.
2777 The changes drastically improve the performance when large rewrite maps
2779 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160

2787 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
2788 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
2790 *) Add %V to mod_log_config, this logs the hostname according to the
2791 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
2792 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
2794 *) Add support for \n and \t to mod_log_config, can be used to produce
2795 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
2797 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]

2803 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
2805 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
2806 is removed. This allows <Directory proxy:*> directives to work and
2807 prevents invalid requests from killing the process.
2808 [Brian Havard <brianh@kheldar.apana.org.au>]

2815 for integration into other HTML sources. David updated the ab man page
2816 as well and added some missing descriptions. Thanks!

2820 characters in the range 0x80 to 0xff (for example accented characters).

2823 *) Added conditional logging based upon environment variables to
2824 mod_log_config. mod_log_referer and mod_log_agent
2825 are now deprecated. [Ken Coar]
2827 *) Allow apache acting as a proxy server to relay the real
2828 reason of a failure to a client rather than the "internal
2829 server error" it does currently. The general exposure mechanism
2830 can be triggered by any module by setting the "verbose-error-to"
2831 note to "*"; this allows more than just proxy errors to be exposed.

2837 *) Added -S option to install.sh so that options can be passed to
2838 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
2840 *) Tweak modules Makefile generated by Configure so that it handles
2841 the test case of no modules being selected. [chaz@reliant.com]
2843 *) Added a <LimitExcept method ...> sectioning directive that allows
2844 the user to assign authentication control to any HTTP method that
2845 is *not* given in the argument list; i.e., the logical negation
2846 of the <Limit> directive. This is particularly useful for controlling
2847 access on methods unknown to the Apache core, but perhaps known by
2848 some module or CGI script. [Roy Fielding, Tony Finch]
2850 *) Prevent apachectl from complaining if the PIDFILE exists but
2851 does not contain a process id, as might occur if the server is
2852 being rapidly restarted. [Wilfredo Sanchez]
2854 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
2856 *) Entity tag comparisons for If-Match and If-None-Match were not being

2867 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
2868 to util.c for parsing an HTTP header field value to extract the next
2869 list item, taking into account the possible presence of nested comments,
2870 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
2871 insignificant whitespace and lowercases non-quoted tokens.
2872 [Roy Fielding] PR#2065
2874 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
2875 code different from 500. This allows the proxy to, e.g., return
2876 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
2878 *) Fix ordering of language variants for the case where the traditional
2879 negotiation algorithm is being used with multiple language variants
2880 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
2882 *) Do not round the TCN quality calculation to 5 decimal places,
2883 unlike RFC 2296, because the calculation might need 12 decimal places
2884 to get the right result. [Roy Fielding]
2886 *) Remove unused code to disable transparent negotiation when
2887 negotiating on encoding only, as we now handle encoding too
2888 (though this is nonstandard for TCN), remove charset=ISO-8859-1
2889 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
2890 some debugging statements within mod_negotiation. [Koen Holtman]
2892 *) Fixed a rare memory corruption possibility in mod_dir if the index
2893 file is negotiable and no acceptable variant can be found.
2894 [Dean Gaudet, Roy Fielding, Martin Kraemer]
2896 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
2897 searching the Win32 registry for script interpreters.
2900 *) Win32: The compiled-in default filename for the error log is now
2901 error.log, which matches the default in the distributed httpd.conf.
2904 *) Win32: Any error messages from -i or -u command line options are now
2905 displayed on the console output rather than sent to the error log.
2906 Also the "Running Apache..." message is not output unless Apache is
2907 going to serve requests. [Paul Sutton]
2909 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
2910 and use a private significator ('$apr1$') to mark passwords as
2911 being smashed with our own algorithm. Also abstract the password
2912 checking into a new ap_validate_password() routine. [Ken Coar]
2914 *) Win32: The filename validity checker now allows "COM" but refuses
2915 access to "COM1" through "COM4". This allows filenames such
2916 as "com.name" to be served. [Paul Sutton] PR#3769.
2918 *) BS2000: Adapt to the new ufork() system call interface which will
2919 make subtasking easier on the OSD/POSIX mainframe environment.
2922 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
2923 ap_compat.h. [David White <david@persimmon.com>] PR#3725
2925 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
2926 use `.db' instead of `.pag' not only for FreeBSD, but also when
2927 the NDBM library looks like Berkeley-DB based.

2933 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
2935 *) SECURITY: Avoid some buffer overflow problems when escaping
2936 quoted strings. (This overflow was on the heap and we believe
2937 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
2939 *) Let src/Configure be aware of CFLAGS options starting with plus
2940 signs as it's the case for the HP/UX compiler.
2941 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
2943 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
2944 and check to see if the tar we wind up with supports '-h'.
2945 [Jim Jagielski] PR#3671
2947 *) A consistent and conservative style for all shell scripts has been
2948 implemented. Basically, all shell string tests use the traditional
2949 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
2950 to protect against bare null variable strings (ie: wrapping both
2951 sides with double quotes and prepending 'x'). 'x' was chosen
2952 because it's more universal and hopefully easier for old shell
2953 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
2956 *) The status module now prints out both the main server generation as
2957 well as the generation of each process. Also, the vhost info is
2958 printed with '?notable'. [Jim Jagielski]
2960 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
2961 and this makes its functions available to things in src/support.
2964 Changes with Apache 1.3.4
2966 *) Renamed macros status_drops_connection to ap_status_drops_connection
2967 and vestigial scan_script_header to ap_scan_script_header_err,
2968 mostly for aesthetic reasons. [Roy Fielding]
2970 *) The query switch "httpd -S" didn't exit after showing the
2971 vhost settings. That was inconsistent with the other query functions.
2974 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
2975 filename to the end of the STANDARD_MODULE_STUFF. Its
2976 presence at the beginning prevented reporting of the filename
2977 for modules compiled before 1 January 1999. [Ken Coar]
2979 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
2980 to detect and prevent access to special DOS device file names.
2981 [Paul Sutton, Ken Parzygnat]
2983 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
2984 and Makefile_win32_debug.txt (debug build) that work on Win95.
2985 Run each of the following from the src directory:
2986 nmake /f Makefile_win32.txt # compiles normal build
2987 nmake /f Makefile_win32.txt install # compiles and installs
2988 nmake /f Makefile_win32.txt clean # removes compiled junk
2989 nmake /f Makefile_win32_debug.txt # compiles debug build
2990 nmake /f Makefile_win32_debug.txt install
2991 nmake /f Makefile_win32_debug.txt clean
2994 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
2995 to build binary distributions. [Lars Eilebrecht]
2997 *) IndexOptions SuppressColumnSorting only turned off making
2998 the column headers anchors; you could still change the display
2999 order by manually adding a '?N=A' or similar query string to the
3000 URL. Now SuppressColumnSorting locks in the sort order so
3001 it can't be overridden this way. [Ken Coar]
3003 *) Added IndexOrderDefault directive to supply a default sort order
3004 for FancyIndexed directory listings. [Ken Coar] PR#1699
3006 *) Change the ap_assert macro to a variant that works on all platforms.
3007 [Richard Prinz <richard.prinz@cso.net>] PR#2575
3009 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
3010 search for an underscore on dlsym() (as it's already the case
3011 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
3013 *) Small fix for mod_env.html: The module was documented as to be _not_
3014 compiled into Apache per default, although it _IS_ compiled into
3015 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
3017 *) Instead of fixing a bug in the generation procedure for config.status (a
3018 backslash was missing) we remove the bug together with it's complete
3019 context because the special cases of the past can now no longer occur
3020 because of the recent magic for the --with-layout default.
3021 [Ralf S. Engelschall] PR#3590
3023 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
3024 making sure the src/support/ tools are _forced_ to be build last (they
3025 depend on other libraries).
3026 [Markus Theissinger <markus.theissinger@gmx.de>]
3028 *) Fix installation procedure: Now that os-inline.c is actually used (a
3029 recently fixed bug prevented this) we need to also install os-include.c
3030 in addition to os.h into the PREFIX/include/ location or building of
3031 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
3033 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
3034 allow us to distinguish between a garbled DSO (or even a file which isn't
3035 an Apache module DSO at all) and a DSO which doesn't match the current
3036 Apache API. [Ralf S. Engelschall] PR#3152
3038 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
3039 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
3040 match case insensitive (this especially avoids nasty patterns like
3041 `[tT][eE][sS][tT]'). Second two additional internal map functions
3042 `escape' and `unescape' were added which can be used to escape/unescape
3043 to/from hex-encodings in URLs parts (this is especially useful in
3044 combination with map lookups).
3045 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
3047 *) Renamed the macro escape_uri() to ap_escape_uri() which was
3048 forgotten (because it was a macro) in the symbol renaming process.
3049 [Ralf S. Engelschall]
3051 *) Fix some inconsistencies related to the scopes of directives. The only
3052 user visible change is that the directives `UseCanonicalName' and
3053 `ContentDigest' now use the (more correct) `Options' scope instead of
3054 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
3056 *) Using DSO, the Server token was being mangled. Specifically, the
3057 module's token was being added first before the Apache token. This
3058 has been fixed. [Jim Jagielski]
3060 *) Major overhaul of mod_negotiation.c, part 2.
3061 - properly handle "identity" within Accept-Encoding.
3062 - allow encoded variants in RVSA negotiation and let them appear in
3063 the Alternates field using the non-standard "encoding" tag-list.
3064 - fixed both negotiation algorithms so that an explicitly accepted
3065 encoding is preferred over no encoding if "identity" is not
3066 included within Accept-Encoding.
3067 - added ap_array_pstrcat() to alloc.c for efficient concatenation
3068 of large substring sequences.
3069 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
3072 *) Major overhaul of mod_negotiation.c, part 1.
3073 - cleanups to mod_negotiation comments and code structure
3074 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
3075 support for everything in the upcoming HTTP/1.1
3076 revision (draft-ietf-http-v11-spec-rev-06.txt).
3077 - language tag matching also handles tags with more than 2
3079 - empty Accept, Accept-Language, Accept-Charset headers are
3080 processed correctly; previously an empty header would make all
3081 values acceptable instead of unacceptable.
3082 - allowed for q values in Accept-Encoding
3083 - added support for transparent content negotiation (rfc2295 and
3084 rfc2296) (though we do not implement all features in these drafts,
3085 e.g. no feature negotiation). Removed old experimental version.
3086 - implemented 'structured entity tags' for better cache correctness
3087 (structured entity tags ensure that caches which can deal with Vary
3088 will (eventually) be updated if the set of variants on the server
3090 - this involved adding a vlist_validator element to request_rec
3091 - this involved adding the ap_make_etag() function to the global API
3092 - modified guessing of charsets used by Apache negotiation algorithm
3093 to guess 'no charset' if the variant is not a text/* type
3094 - added code to sort multiviews variants into a canonical order so that
3095 negotiation results are consistent across backup/restores and mirrors
3096 - removed possibility of a type map file resolving to another type map
3097 file as its best variant
3098 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
3100 *) RFC2396 allows the syntax http://host:/path (with no port number)
3101 but the proxy disallowed it (ap_proxy_canon_netloc()).
3102 [David Kristol <dmk@bell-labs.com>] PR#3530
3104 *) When modules update/modify the file name in the configfile_t structure,
3105 syntax errors will report the updated name, not the original one.

3108 *) Correct some filename case assumptions from WIN32 to
3109 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]
3111 *) For %v log ServerName regardless of the UseCanonicalName
3112 setting (similarly for %p). [Dean Gaudet]
3114 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
3115 rather late (too late for some invocations of TestCompile).
3116 This improves the make environment available to TestCompile and
3117 the *.module scripts. [Martin Kraemer]
3119 *) The hashbang emulation code in ap_execve.c would interpret
3120 #!/hashbang/scripts correctly, but failed to fall back to a
3121 standard shell for scripts which did NOT start with #!
3122 Now SHELL_PATH is started in these cases. [Martin Kraemer]
3124 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
3127 *) Update APXS manual page: some -q option arguments were missing
3128 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
3130 *) Cleanup the command line options: `-?' was documented to show
3131 the usage list but does it with an error because `?' is not a valid
3132 command. OTOH a lot of users expect `-h' to print such a usage list and
3133 instead are annoyed for ages by our huge unreadable list of directives.
3134 So we now changed the command line options this way:
3136 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
3137 very similar to the popular linker option.
3139 Intent: while -l gives the small list of modules, -L now gives the
3140 large list of directives implemented by these modules. This is also
3141 consistent with -v (short version info) and -V (large version info).
3143 Intent: it's now the expected option ;-)
3144 The manual page was adjusted accordingly.
3145 [Ralf S. Engelschall] PR#2714
3147 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
3148 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
3150 *) Removed recently introduced bugs and disfigurements in APACI:
3151 o fixed argument line processing: using $args was broken: It was not
3152 initialized and using args="$args $apc_option" and even args="$args
3153 \"$apc_option\"" fails in the second processing round for any arguments
3154 containing whitespaces. The only correct way is to use the construct
3155 "$@" (but not possible here) or iterate _both_ times over the implicit
3156 argument line (no argument to for-loop) which is what we now use.
3157 o make --with-layout=Apache the default without creating
3158 redundancy (copying the --with-layout block in the argument parsing
3159 loop). We achieve this by using the "$@" construct together with the
3160 `set' command to prepend --with-layout=Apache to the command line in
3161 case --with-layout is not used.
3162 o fixed auto-suffix handling now that config.layout exists.
3163 Paths which are auto-suffixed are marked with a trailing plus sign in
3164 config.layout and every path now can be marked this way (not only the
3165 four paths for which we do it currently). Additionally the suffix is
3166 no longer a static one. Instead it's now `/<target>' where <target> is
3167 the argument of the --target option or per default `httpd'.
3168 o allow also tabs (and only spaces) where we match whitespaces
3169 o various fixes and cleanups related to used shell coding style
3170 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
3171 o trimmed output of --help to fit into 80 columns
3172 [Ralf S. Engelschall]
3174 *) Added two new core API functions, ap_single_module_configure() and
3175 ap_single_module_init(), which are now used by mod_so to configure a module
3176 after loading. [Ralf S. Engelschall]
3178 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
3179 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
3180 of ap_config.h to allow serialized accept for multiport listens.
3181 [Roy Fielding, Curt Sampson] PR#3120
3183 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
3184 of ap_config.h that would skip several defines if DEFAULT_GROUP
3185 was overridden. [Roy Fielding]
3187 *) PORT: The I86 version of DGUX has support for strncasecmp and
3188 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
3190 *) Fix ordering of definitions in ap_config.h so that ap_inline is
3191 defined before it might be used. [Victor Khimenko]
3193 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
3194 [Tom Serkowski <tks@bsdi.com>] PR#3453
3196 *) Make generation of src/Configuration.apaci more robust: It failed to
3197 differenciate between modules when one module name was a postfix of
3198 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
3199 just XXX (think about totally non-standard names like "apache_ssl", too).
3200 [Ralf S. Engelschall] PR#3380
3202 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
3203 since 1.3b7) and make whitespace handling more robust (it failed horrible
3204 when whitespaces were present in the arguments of -D options).
3205 [Ralf S. Engelschall] PR#3240
3207 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
3208 creates an external package shadow tree in DIR before the local build
3209 shadow tree is generated under DIR. This way one can have the extracted
3210 Apache distribution tree read-only on NFS or CDROM and still build Apache
3211 from these sources. An automatically triggered VPATH-like mechanism is
3212 provided through the TOP variable, too.
3213 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez@apple.com>]
3215 *) Fix negotiation so that a Vary response header is correctly
3216 generated when, for a particular dimension, variants only vary
3217 in having or not having a value for that dimension. [Paul Sutton]
3219 *) Fix negotiation so that we prefer an encoded variant over an
3220 unencoded variant if the user-agent explicitly says it can
3221 accept that encoding. Previously we always preferred the unencoded
3223 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
3225 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
3226 and the usage page was inconsistent with the functionality and manpage.
3227 [Ralf S. Engelschall]
3229 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
3230 They can occur multiple times and their arguments (`xxx') are passed AS
3231 IS to the compiler/linker command. [Ralf S. Engelschall]
3233 *) Fixed possible (but harmless in practice) bug in the DBM lookup
3234 procedure of mod_rewrite: very long keys were truncated.
3235 [Ralf S. Engelschall]
3237 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
3238 identifier, currently "Apache" and "GNU" are pre-defined in the file
3239 config.layout. Custom layouts are possible by using FILE:ID as the
3240 argument where the layout ID is taken from FILE.
3242 The config.layout file consists of <Layout ID>..</Layout> sections
3243 where inside those sections "path_variable: path_value" pairs can be
3244 specified. These lines are converted to path_variable='path_value'.
3246 *) Add a DefaultLanguage directive so that files missing a language
3247 extension (e.g., .fr, .de) can be labelled as being some other
3248 default language. DefaultLanguage can appear in <Directory> and
3249 <Files> containers as well as .htaccess files. [Paul Sutton]
3252 *) Fix TARGET configuration when configuring and installing using
3253 APACI configure. TARGET now defines the basename of the configuration
3254 file, startup script, manual page, etc. log_error_core() now reports
3255 the server binary name given by argv[0]. TARGET can now also be defined
3256 with --target=TARGET parameter passed to APACI configure.
3257 [Ralf Engelschall, Randy Terbush]
3259 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
3260 rather than OPT_INCLUDES [Rainer Schoepf <schoepf@uni-mainz.de>]

3349 unavailable, an empty string was printed which was 2 bytes short.
3350 The size and description columns were therefore not aligned correctly.
3351 [Martin Kraemer] (no PR#)
3353 *) Update BS2000 OS code to work with recent versions. Starting with
3354 release A17, the child fork() must be replaced by a _rfork().
3355 (BS2000 only) [Martin Kraemer]
3357 *) Add the actual server_rec structure of the specific Vhost to the
3358 scoreboard file and avoid a string copy (as well as allow some
3359 further future enhancements). [Harrie Hazewinkel
3360 <harrie.hazewinkel@jrc.it>]
3362 *) Add APACI --permute-module=foo:bar option which can be used to
3363 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
3364 in the Configuration[.apaci] file. Two special and important variants are
3365 supported for the option argument: first BEGIN:foo which permutes module
3366 mod_foo with the begin of the module list, i.e. it `moves' the module to
3367 the begin of the list (gives it lowest priority). And second foo:END
3368 which permutes mod_foo with the end of the module list, i.e. it `moves'
3369 the module to the end of the list (gives it highest priority).
3370 [Ralf S. Engelschall]
3372 *) Fix problem with 'apache -k shutdown' and startup event
3373 synchronisation (Win32). [Ken Parzygnat <kparz@raleigh.ibm.com>]
3376 *) The config parser wasn't correctly noticing a missing '>'
3377 on container start lines (e.g., it wouldn't spot
3378 "<Directory /" as a syntax error). [Ryan Bloom <rbbloom@us.ibm.com>]
3381 *) Add a 'RemoveHandler' directive which will selectively remove
3382 all handler associations for the specified file extensions.
3383 [Ryan Bloom <rbbloom@us.ibm.com>] PR#1799.
3385 *) Properly handle & allow "nul" and ".*/null" in AccessConfig and
3386 ResourceConfig directives on Win32. Also add a note to the effect
3387 of 'useless User directive ignored on Win32' to the errorlog if
3388 a User directive is encountered on Win32.
3389 [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2078, 2303.
3391 *) Fix multiple whitespace handling in imagemaps for mod_imap which was
3392 broken since Apache 1.3.1 where we took out compressing of multiple
3393 spaces in ap_cfg_getline().
3394 [Ivan Richwalski <ivan@seppuku.net>] PR#3249
3396 *) Fix Berkeley-DB/2.x support in mod_auth_db: The data structures were not
3397 initialized correctly and the db_open() call used an invalid mode
3398 parameter. [Ron Klatchko <ron@ckm.ucsf.edu>] PR#3171
3400 *) PORT: DSO support for UnixWare 7
3401 [Ralf S. Engelschall, Ron Record <rr@sco.com>]
3403 *) Merge the contents of the {srm,access}.conf-dist* files into the
3404 httpd.conf-dist* files. The srm and access files now contain
3405 only comments, and httpd.conf has all the combined contents in
3406 a rational order. [Ken Coar]
3408 *) PORT: DSO/ELF support for FreeBSD 3.0.
3409 [Ralf S. Engelschall, Dirk Froemberg <ibex@physik.TU-Berlin.DE>]
3411 *) Add a "default-handler" handler that calls the default_hander()
3412 function which is normally called for static content. This allows
3413 you to override a specific handler. [Marc Slemko]
3415 *) Further simplify checking for absolute paths by replacing an
3416 hard-coded syntax check with a call to a routine we already created to
3417 do this. [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2976, 3074
3419 *) Log an error if we encounter a malformed "require" directive
3420 in mod_auth if we know that we know that no other module can
3421 deal with it. [Marc Slemko]
3423 *) Remove ap_private_extern method of hiding conflicting symbols
3424 on the NEXT platform because it is not correct for all versions,
3425 and the versions for which it is correct are unknown.
3426 [Wilfredo Sanchez <wsanchez@apple.com>]
3428 *) Fix inheritance of IndexOptions NameWidth and remove unintended
3429 restriction on +NameWidth, +IconHeight, and +IconWidth. [Ken Coar]
3431 *) Fix per-directory config merging for cases in which a 500 error
3432 is encountered in an .htaccess file somewhere down the tree.
3435 *) Minor performance improvement to ap_escape_html(). [Roy Fielding]
3437 *) Fixed a segmentation violation in mod_proxy when a response is
3438 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
3440 Changes with Apache 1.3.3
3442 *) Added a complete implementation of the Expect header field as
3443 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
3444 response when we already know the final status, which is mighty
3445 useful for PUT responses that result in 302 or 401. [Roy Fielding]
3447 *) Remove extra trailing whitespace from the getline results as part
3448 of the protocol processing, which is extra nice because it works
3449 between continuation lines, is almost no cost in the normal case
3450 of no extra whitespace, and saves memory. [Roy Fielding]
3452 *) Added new HTTP status codes and default response bodies from the
3453 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
3454 HTTP Extension Framework (510) specifications. Did not add the
3455 WebDAV 424 and 425 codes because they are bogus. We don't use any
3456 of these codes yet, but they are now available to 3rd-party modules.
3459 *) Fix a possible race condition between timed-out requests and the
3460 ap_bhalfduplex select that might result in an infinite loop on
3461 platforms that do not validate the descriptor. [Roy Fielding]
3463 *) WIN32: Add "-k shutdown" and "-k restart" options to signal a
3464 running Apache server [Paul Sutton]
3466 *) Fix mod_autoindex bug where directories got a size of "0k" instead
3467 of "-". [Martin Plechsmid <plechsmi@karlin.mff.cuni.cz>, Marc Slemko]
3470 *) PORT: DRS 6000 machine. [Paul Debleecker <pdebleecker@jetair.be>]
3472 *) Add the server signature text (from the core ServerSignature directive)
3473 to the list of envariables available to scripts, SSI, and the like.
3476 *) PORT: Fix sys/resource.h handling for SCO 3.x platform.
3477 [M. Laak <maert@proinv.ee>] PR#3108
3479 *) Fallback from sysconf-based to plain HZ-based `ticks per second'
3480 calculation in mod_status for all systems which don't have POSIX
3481 sysconf() (like UTS 2.1) and not only for the NEXT platform.
3482 [Dave Dykstra <dwd@bell-labs.com>] PR#3055
3484 *) Fix `require ...' directive parsing in mod_auth, mod_auth_dbm and
3485 mod_auth_db by using ap_getword_white() (which uses ap_isspace())
3486 instead of ap_getword(..., ' ') (which parses only according to spaces
3487 but not tabs). [James Morris <jmorris@intercode.com.au>,
3488 Ralf S. Engelschall] PR#3105
3490 *) Fix the SERVER_NAME variable under sub-request situations (where
3491 `UseCanonicalName off' is used) like CGI's called from SSI pages or
3492 RewriteCond variables by adopting r->hostname to sub-requests.
3493 [James Grinter <jrg@blodwen.demon.co.uk>] PR#3111
3495 *) Fix stderr redirection under syslog-based error logging situation.
3496 [Youichirou Koga <y-koga@jp.FreeBSD.org>] PR#3095

3501 *) Fix http://localhost/ hints in top-level INSTALL document.
3502 [Rob Jenson <robjen@spotch.com>, Ralf S. Engelschall] PR#3088
3504 *) Quote paths in default configuration files. [Wilfredo Sanchez]
3506 *) PORT: Remove extra HAVE_SYS_RESOURCE_H define for RHAPSODY since
3507 it is now taken care of properly by the header file tests.
3508 [Wilfredo Sanchez <wsanchez@apple.com>]
3510 *) Fix problem with scripts and filehandle inheritance on Win32.
3511 [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2884, 2910
3513 *) Win32 name canonicalisation could end up using the server's
3514 working directory to fill in some blanks. [Ken Parzygnat
3515 <kparz@raleigh.ibm.com>] PR#3001
3517 *) Correct invalid assumption by ap_sub_req_lookup_file() that all
3518 absolute paths begin with "/" -- because they don't on Win32.
3519 [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2976, 3074
3521 *) Add [REDIRECT_]VARIANTS environment variable to mod_speling
3522 so that ErrorDocument 300 processors can reformat the list
3523 if desired. [Ken Coar] PR#2859
3525 *) Add +/- incremental prefixes to IndexOptions keywords, and
3526 enable merging of multiple IndexOptions directives. [Ken Coar]
3528 *) PORT: Allow GuessOS to recognize Unixware 7.0.1 [Steve Cameron
3529 <steve.cameron@compaq.com>]
3531 *) Reconstructed the loop through multiple htaccess file names so
3532 that missing files are not confused with unreadable files.
3535 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
3536 errno on an error, which leads to one error being mistaken for
3537 another when reading non-existent .htaccess files.
3540 *) OS/2: The new header tests get things right, need to update
3541 ap_config.h. [Brian Havard]
3543 *) The Perl %ENV hash will now be setup by default when using the
3544 mod_include `perl' command [Doug MacEachern]
3546 *) PORT: Add Pyramid DC/OSx support to configuration mechanism.
3547 [Earle Ake <akee@wpdiss1.wpafb.af.mil>]

3552 *) Correct comment in mod_log_config.c about its internals.
3553 [Elf Sternberg <elf@halcyon.com>]
3555 *) Avoid possible line overflow in Configure: Use an awkfile to
3556 handle the creation of modules.c [Jim Jagielski]
3558 Changes with Apache 1.3.2
3560 *) Fix bug in ap_remove_module(), which caused problems for dso's
3561 who were the top_module. [Doug MacEachern]
3563 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
3564 mod_auth_db to both be friendly to users who wants to use this version
3565 and to avoid problems under platforms where only version 2.x is present.
3566 [Dan Jacobowitz <drow@false.org>, Ralf S. Engelschall]
3568 *) When using ap_log_rerror(), make the error message available to the
3569 *ERROR_NOTES envariables by default. [Ken Coar]
3571 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
3572 You now must define a BS2000Account name for the server User.
3573 This has fewer security implications than the old approach.
3576 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
3577 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
3578 platform to make the braindead HPUX linker happy. Notice, for the module
3579 DSOs we don't have to use this, because these are loaded manually (and
3580 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
3582 *) Remove 64 thread limit on Win32.
3583 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3585 *) Remove redundant substitutions in top-level Makefile.tmpl.
3586 [Ralf S. Engelschall]
3588 *) Fix APACI's `Group' configuration adjustment - especially for Linux
3589 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
3591 *) Make PrintPath work generically instead of having one version
3592 strictly for OS/2. [Jim Jagielski, Brian Havard]
3594 *) Fix the recently introduced C header file checking: We now use the C
3595 pre-processor pass only (and no longer the complete compiler pass) to
3596 determine whether a C header file exists or not. Because only this way
3597 we're safe against inter-header dependencies (which caused horrible
3598 portability problems). The only drawback is that we now have a CPP
3599 configuration variable which has to be determined first (we do a similar
3600 approach as GNU Autoconf does here). When all fails the user still has
3601 the possibility to override it manually via APACI or src/Configuration.
3602 As a fallback for the header check itself we can directly check the
3603 existance of the file under /usr/include, too.
3604 [Ralf S. Engelschall] PR#2777
3606 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined
3607 as an alternate mechanism for mmap'd shared memory for RHAPSODY.
3608 ap_private_extern defined to hide symbols that conflict with loaded
3609 dynamic libraries on the NEXT and RHAPSODY platforms.

3624 *) Fix possible buffer overflow situation in suexec.c.
3625 [Jeff Stewart <jws@purdue.edu>] PR#2790
3627 *) Add some more LIBS for the SCO5 platform which are needed for the already
3628 used -lprot. It's actually a bug in SCO5, of course.
3629 [Ronald Record <rr@sco.com>] PR#2533
3631 *) Fix documentation of ProxyPass/ProxyPassReverse according to the
3632 trailing slash problem. [Jon Drukman <jsd@gamespot.com>] PR#2933
3634 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
3635 platform, because it's only supported under version 4.0 and higher. But
3636 because our GuessOS is still unaware of Digital UNIX versions and the
3637 -msym is just to optimize the DSO statup time a little bit it's safe and
3638 best when we leave it out now. [Ralf S. Engelschall] PR#2969
3640 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
3641 functions: First all three functions no longer fail on strings containing
3642 "%" chars and second ap_log_printf() no longer does a double-formatting
3643 (instead it directly passes through the message to be formatted to the
3644 real internal formatting function). [Ralf S. Engelschall] PR#2941
3646 *) Allow "Include" directives anywhere in the server config
3647 files (but not .htaccess files). [Ken Coar] PR#2727
3649 *) The proxy was refusing to serve CONNECT requests except to
3650 port 443 (https://) and 563 (snews://). The new AllowCONNECT
3651 directive allows the configuration of the ports to which a
3652 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
3654 *) mod_expires will now act on content that is not sent from a file
3655 on disk. Previously it would never add an Expires: header to
3656 any response that did not come from a file on disk; the only
3657 case where it still doesn't (and can't) add one for that type of
3658 content is if you are using a modification date based setting.
3659 [Marc Slemko, Paul Phillips <paulp@go2net.com>]
3661 *) Problems encountered during .htaccess parsing or CGI execution
3662 that lead to a "500 Server Error" condition now provide explanatory
3663 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
3666 *) Add NameWidth keyword to IndexOptions directive so that the
3667 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
3670 *) Recognize lowercase _and_ uppercase `uname' results under
3671 SCO OpenServer. [David Coelho <drc@ppt.com>]
3673 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
3674 a common problem of (mis-administrated?) IIS servers, make the apache
3675 proxy immune to these errors (and ignore the duplicates, but log
3676 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
3678 *) The <IfModule and <IfDefine block starting directives now only
3679 allow exactly one argument. Previously, the optional negation
3680 character '!' could be separated by whitespace without a syntax
3681 error being reported, albeit defeating the IfModule functionality
3682 (enclosed directives would ALWAYS be executed). By using the
3683 stricter syntax, these hard-to-track errors can be avoided.
3686 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
3687 cause the standalone FancyIndexing directive to logically OR
3688 into any existing IndexOptions settings rather than wiping
3689 them out. [Ken Coar]
3691 *) Changes in ftp proxy: make URL parsing simpler by using the
3693 + Add display of the "current directory" in cases where it's
3694 different from the supplied path (e.g., ftp://user@host/ lives
3695 in /home/user, not in /, therefore clicking on "../" in the
3696 starting directory might send us to /home/).
3697 + When ftp login fails, (esp. when a user name was part of the
3698 URL already), we now return [401 Unauthorized ] to allow the
3699 browser to pop up an authorization dialog. This makes passwords
3700 slightly less visible (they don't appear in the regular log files)
3701 and implements a functionality that other www proxy servers
3705 *) Triggered by the recent "Via:" header changes, the proxy module would
3706 dump core for replies with invalid headers (e.g., duplicate
3707 "HTTP/1.0 200 OK" lines). These errors are now logged and the
3708 core dump is avoided. Also, broken replies are not cached.
3709 [Martin Kraemer] PR#2914
3711 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
3712 plop gmon.out profile data for each child [Doug MacEachern]
3714 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
3715 config.status script to be immune against arguments with whitespaces.
3716 [Yves Arrouye <yves@apple.com>] PR#2866
3718 *) Replace the inlined information grabbing stuff for the configuration
3719 adjustment feature (no --without-confadjust) with calls to a new helper
3720 script `buildinfo.sh' which is both more flexible and already proofed to
3721 be more robust against platform differences. This mainly fixes the
3722 recently occured ``sed: command garbled: ...'' problems.
3723 [Ralf S. Engelschall] PR#2776, PR#2848
3725 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
3726 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
3727 without complains after we recently added the POST feature.
3728 [Ralf S. Engelschall]
3730 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
3731 modules as API functions and we forgot them at the big symbol renaming.
3732 [Ralf S. Engelschall]
3734 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html
3735 [Youichirou Koga <y-koga@jp.FreeBSD.ORG>] PR#2895
3737 *) Dynamically size the filename column of mod_autoindex output.
3740 *) Add the ability to do POST requests to the ab benchmarking tool.
3741 [Kurt Sussman <kls@best.com>] PR#2871
3743 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
3744 5 to 10 because there are some users out there who always have 5 to 8
3745 variables in one RewriteRule and had to patch mod_rewrite.h for every
3746 release. So 15 should be now more than enough, even for them. (I never
3747 needed more than 4 in my RewriteRules ;-)
3748 [Ralf S. Engelschall]
3750 *) Make the proxy generate and understand Via: headers
3753 *) Change the proxy to use tables instead of array_headers for
3754 the header lines. [Martin Kraemer]
3756 *) Make sure the config.status file is not overridden when just
3757 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
3759 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
3760 provide a way to trace API changes that add functionality but do
3761 not create a compatibility issue for precompiled modules, etc.
3762 See include/ap_mmn.h for more details. [Randy Terbush]
3764 *) Fix suexec installation under `make install root=xxx' situation.
3765 [Ralf S. Engelschall]
3767 *) Extend the output of the -V switch to include the paths of all
3768 compiled-in configuration files, if they were overridden at
3769 compile time, for least astonishment of the user.
3772 *) When READing a request in ExtendedStatus mode, the "old"
3773 vhost, request and client information is not displayed.
3776 *) STATUS is no longer available. Full status information now
3777 run-time configurable using the ExtendedStatus directive.
3780 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
3781 cpu time attacks) in header parsing. Add ap_overlap_tables(),
3782 a function which can be used to perform bulk update operations
3783 on tables in a more efficient manner. [Dean Gaudet]
3785 *) SECURITY: Added compile-time and configurable limits for
3786 various aspects of reading a client request to avoid some simple
3787 denial of service attacks, including limits on maximum request-line
3788 size (LimitRequestLine), number of header fields (LimitRequestFields),
3789 and size of any one header field (LimitRequestFieldsize). Also added
3790 a configurable directive LimitRequestBody for limiting the size of the
3791 request message body. [Roy Fielding]
3793 *) Make status module aware of DNS and logging states, even if
3794 STATUS not defined. [Jim Jagielski]
3796 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
3798 *) Enhance mod_speling so that CheckSpelling can be used in
3799 <Directory> containers and .htaccess files. [Ken Coar]
3801 *) API: new ap_custom_response() function for hooking into the
3802 ErrorDocument mechanism at runtime [Doug MacEachern]
3804 *) API: new ap_uuencode() function [Doug MacEachern]
3806 *) API: scan_script_header_err_core() now "public" and renamed
3807 ap_scan_script_header_err_core() [Doug MacEachern]
3809 *) The 'status' module will now show the process pid's and their
3810 state even without full STATUS accounting. [Jim Jagielski]
3812 *) Restore the client IP address to the error log messages, this
3813 was lost during the transition from 1.2 to 1.3. Add a new
3814 function ap_log_rerror() which takes a request_rec * and
3815 formats it appropriately. [Dean Gaudet] PR#2661
3817 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
3818 whitespace in input lines -- including within quoted strings.
3820 but leading and trailing whitespace should continue to be
3821 stripped [Martin Kraemer]
3823 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
3824 the ugly use of an env. variable and use command-line args for
3825 alternate $PATH. Make more like advanced 'type's as well.
3828 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
3829 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
3830 <alain.st-denis@ec.gc.ca>] PR#2736
3832 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
3834 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
3835 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
3836 directory was renamed to src/os/os2/ for consistency.
3837 [Brian Havard, Ralf S. Engelschall]
3839 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
3840 files (here modules) against other DSO files (here shared libraries).
3841 This is done by determining a subset of LIBS which can be safely used for
3842 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
3843 disabled for all platforms to avoid problems with this (experimental)
3844 rule. But we provide it now for those people how ran into problems and
3845 want to came out by forcing linking against DSOs.
3846 [Ralf S. Engelschall] PR#2587

4149 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
4150 in top-level configure script to avoid sed fails on some platforms (for

4152 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
4154 *) Improve performance of directory listings (mod_autoindex) by comparing
4155 integer keys (last-modified and size) as integers rather than converting
4156 them to strings first. Also use a set of explicit byte tests rather
4157 than strcmp() to check for parent directory-ness of an entry. Oh, and
4158 make sure the parent directory (if displayed) is *always* listed first
4159 regardless of the sort key. Overall performance winnage should be good
4160 in CPU time, instruction cache, and memory usage, particularly for large
4161 directories. [Ken Coar]
4163 *) Add a tiny but useful goody to APACI's configure script: The generation
4164 of a config.status script (as GNU Autoconf does) which remembers the used
4165 configure command and hence can be used to restore the configuration by
4166 just re-running this script or for remembering the configuration between

4170 *) Add httpd -t (test) option for running configuration syntax tests only.
4171 If something is broken it complains and exits with a return code
4172 non-equal to 0. This can be used manually by the user to check the Apache
4173 configuration after editing and is also automatically used by apachectl
4174 on (graceful) restart command to make sure Apache doesn't die on restarts
4175 because of a configuration which is now broken since the last (re)start.
4176 This way `apachectl restart' can be used inside cronjobs without having
4177 to expect Apache to be falling down. Additionally the httpd -t can be run
4178 via `apachectl configtest'.

4345 *) Transform the configure message "You need root privileges for suEXEC"
4346 from a fatal error into a (more friendly) warning because the building
4347 ("make") of Apache we can allow, of course. Root privileges are needed
4348 only for the installation step ("make install"). So make sure the
4349 user is aware of this fact but let him proceed as long as he can.
4350 [Ralf S. Engelschall] PR#2288
4352 *) Renamed three more functions to common ap_ prefix which we missed at the
4353 Big Symbol Renaming because they're #defines and not real C functions:
4354 is_default_port(), default_port(), http_method().
4355 [Ralf S. Engelschall]
4357 *) A zero-length name after a $ in an SSI document should cause
4358 just the $ to be in the expansion. This was broken during the
4359 security fixes in 1.2.5. [Dean Gaudet] PR#1921, 2249
4361 *) Call ap_destroy_sub_req() in ap_add_cgi_vars() to reclaim some
4362 memory. [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2252
4364 *) Fix src/support/httpd.exp (DSO export file which is currently only
4365 used under AIX) because of recent changes to function names.
4366 [Ralf S. Engelschall]
4368 Changes with Apache 1.3b7
4370 *) Make sure a MIME-type can be forced via a RewriteRule even when no
4371 substitution takes place, for instance via the following rule:
4372 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
4373 requested by users in the past to force a single script without a .cgi
4374 extension and outside any cgi-bin dirs to be executed as a CGI program.
4375 [Ralf S. Engelschall] PR#2254
4377 *) A fix for protocol issues surrounding 400, 408, and
4378 414 responses. [Ed Korthof]
4380 *) Ignore MaxRequestsPerChild on WIN32. [Brian Behlendorf]
4382 *) Fix discrepancy in proxy_ftp.c which was causing failures when
4383 trying to connect to certain ftpd's, such as anonftpd.
4384 [Rick Ohnemus <rick@ecompcon.com>]
4386 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
4387 logfile instead of fiddling around itself with child spawning stuff.
4388 [Ralf S. Engelschall]
4390 *) Made RefererIgnore case-insensitive.
4392 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
4395 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
4396 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
4399 *) Improve RFC1413 support. [Bob Beck <beck@bofh.ucs.ualberta.ca>]
4401 *) Fix support script `dbmmanage': It was unable to handle some sort
4402 of passwords, especially passwords with "0" chars.
4403 [Ralf S. Engelschall] PR#2242
4405 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
4406 [Ben Laurie] PR#2238
4408 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
4409 library), so CGI handling has been changed to use Win32 native handles
4410 instead of C file descriptors.
4411 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
4413 *) The proxy cache would store an incorrect content-length in the cached
4414 file copy after a cache update. That resulted in repeated fetching
4415 of the original copy instead of using the cached copy.
4416 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
4418 *) The Makefiles assumed that DSO files are build via $(LD). This
4419 is broken for two reasons: First we never defined at least LD=ld
4420 somewhere to make sure this works (it was silently assumed that most Make
4421 provide a built-in LD definition - ARGL!) and second using the generic LD
4422 variable is not the truth. Instead a special variable named LD_SHLIB is
4423 reasonable because although "ld" is usually the default, the command for
4424 building DSO files can be "libtool" or even "cc" on some systems.
4425 [Ralf S. Engelschall]
4427 *) Replace the AddVersionPlatform directive with ServerTokens which
4428 provides for more control over the format of the Server:
4429 header line. SERVER_SUBVERSION is no longer supported;
4430 all module should use the ap_add_version_component()
4431 API function instead. [Jim Jagielski]
4433 *) Support for the NCR MP/RAS 3.0
4434 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
4436 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
4437 not retrieved in src/Configure and thus was not useable.
4438 [Ralf S. Engelschall]
4440 *) Various Makefile consistency cleanups:
4441 - make OSDIR also automatically be relative to src/ like INCDIR
4442 - SUBDIRS is now generated in src/Makefile only and not in
4443 Makefile.config because it is a local define for this location.
4444 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
4445 any Makefile but make sure that at least the "-K inline" is kept in
4447 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
4448 - updated the dependencies theirself
4449 - removed not existing SHLIB variable from "clean" targets
4450 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
4451 already exists and OBJS_PIC are also just plain objects and have not
4452 directly to do with "shared" things. The only difference is that they
4453 contain PIC. So OBJS_PIC is the more canonical name.
4454 - Updated the Makefile-dependency lines for OBJS_PIC
4455 - Removed the Makefile-dependency line in Configure to avoid double
4457 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
4458 of xxx.lo as GNU libtool does with its PIC objects
4459 - reduce local complexity in modules Makefile.tmpl by moving the last
4460 existing target "depend" to the generation section in Configure, too.
4461 - removed the historical $(SPACER) which was used in the past together
4462 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
4463 is no longer needed.
4464 - force the build and run of the gen_xxx programs under main/ as the
4465 first step before building the objects because it looks cleaner
4466 [Ralf S. Engelschall]
4468 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
4471 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
4474 *) WIN32: Don't force ISAPI headers to finish with \n.
4475 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
4477 *) When opening "configuration" files (like httpd.conf, htaccess
4478 and htpasswd), Apache will not allow them to be non-/dev/null
4479 device files. This closes a DoS hole. At the same time,
4480 we use ap_pfopen to open these files to handle timeouts.
4481 [Jim Jagielski, Martin Kraemer]
4483 *) Apache will now log the reason its httpd children exit if they exit
4484 due to an unexpected signal. (It requires a new porting define,
4485 SYS_SIGLIST, which if defined should point to a list of text
4486 descriptions of the signals available. See PORTING.) [Dean Gaudet]
4488 *) WIN32: chdir() doesn't make sense in a multithreaded environment
4489 like WIN32. Before, Win32 CGI's could have had sporadic failures
4490 if a chdir call from one thread was made between another chdir call
4491 and a spawn in another thread. So, for now don't chdir for CGI scripts
4492 in WIN32. The current CGI "spec" is unclear as to whether it's
4493 necessary. Long-term fix is to either serialize the chdir/spawn combo
4494 or use WIN32 native calls to spawn a process. This temp fix was
4495 necessary to remove this as a showstopper for 1.3's release.
4498 *) Cleanup the suEXEC support in APACI and make it more safe:
4499 1. Add big fat hint in INSTALL about risks and to read the
4500 htdocs/manual/suexec.html document before using the suexec-related
4502 2. Make sure the user has at least provided one --suexec-xxxx option
4503 (specifies suEXEC parameters) in addition to --enable-suexec option.
4504 If only --enable-suexec is given APACI stops with a hint to INSTALL
4505 and htdocs/manual/suexec.html documents.
4506 3. Provide two additional --suexec-xxxx options to make the suEXEC
4507 configuration complete (especially for package maintainers who else
4508 had to patch the source tree) by providing ways to configure minimal
4509 UID/GID and safe PATH, too.
4510 [Ralf S. Engelschall]
4512 *) Cleanup of the `configure --shadow' process:
4513 - make sure the configure script creates its temporary files in the
4514 shadow tree to avoid conflicts with parallel configure runs
4515 - removed unnecessary option "-r" from "rm" call for Makefiles
4516 - make sure the configure scripts creates the shadow-wrapper Makefile
4517 only when no shadow trees already exists
4518 - make sure "make distclean" removes the shadow-wrapper Makefile but only
4519 when no more shadow trees exists
4520 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
4521 as fast (in the past it needed 70sec, now it runs just 38sec)
4522 - make sure CVS does not complain about the created files
4523 Makefille.<gnutriple> and directories src.<gnutriple>
4524 [Ralf S. Engelschall]
4526 *) Added the ap_add_version_component() API routine and the
4527 AddVersionPlatform core directive. The first allows modules to
4528 declare themselves in the Server response header field value,
4529 augmenting the SERVER_SUBVERSION define in the Configuration file
4530 with run-time settings (more useful in a loadable-module environment).
4531 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
4532 into the server version string. [Ken Coar] PR#2056
4534 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
4537 *) Emit the "Accept-Range" header for the default handler.
4538 [Brian Behlendorf] PR#1464
4540 *) Add a note to httpd.conf-dist that apache will on some systems fail
4541 to start when the Group # is set to a negative or large positive value.
4544 *) Make sure the module execution order is correct even when some modules
4545 are loaded under runtime (`LoadModule') via the DSO mechanism:
4546 1. The list of loaded modules is now a dynamically allocated one
4547 and not the original statically list from modules.c
4548 2. The loaded modules are now correctly setup by LoadModule for
4549 later use by the AddModule command.
4550 3. When the DSO mechanism for modules is used APACI's `install'
4551 target now enables all created `LoadModule' lines per default because
4552 this is both already expected by the user _and_ needed to avoid
4553 confusion with the next point and reduces the Makefile.tmpl complexity
4554 4. When the DSO mechanism for modules is used, APACI's `install'
4555 target now additionally makes sure the module list is reconstructed
4556 via a complete `ClearModuleList+AddModule...' entry.
4557 5. The support tool `apxs' now also makes sure an AddModule command
4558 is added in addition to the LoadModule command.
4559 6. The modules.c generation was extended to now contain two
4560 comments to make sure no one is confused by the confusing terminology
4561 of loading/linking (we use load=link+load & link=activate instead of
4562 the obvious load=activate & link=link :-( )
4563 This way now there is no longer a difference under execution time between
4564 statically and dynamically linked modules.
4565 [Ralf S. Engelschall]
4567 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
4568 Big Symbol Renaming. [Ralf S. Engelschall]
4570 *) Add a comment to mod_example.c showing the format of a FLAG command
4573 *) Standardized the time format in mod_status to match that of other
4574 places in the code (e.g. DATE_GMT). PR#1551
4576 *) Fix handling of %Z in timefmt strings for those platforms with no time
4577 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
4580 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
4581 feature compatible with 'UseCanonicalName off' by changing
4582 r->server->server_hostname to ap_get_server_name(). And I changed some
4583 functions which use r->server->port to use ap_get_server_port() instead,
4584 because if there's no Port directive in the config r->server->port is 0.
4587 *) get/set_module_config are trivial enough to be better off inline. Worth
4588 1.5% performance boost. [Dean Gaudet]
4590 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
4591 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
4594 *) [BS2000 security] BS2000 needs an extra authentication to initialize
4595 the task environment to the unprivileged User id. Otherwise CGI scripts
4596 would have a way to gain super user access. [Martin Kraemer]
4598 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
4599 absolute path, only log base name of logging source as is done
4600 in unix. [Martin Kraemer]
4602 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
4603 the encoding type from the Accept-Encoding header (if it's there)
4604 and use it in the response, as that's probably what it'll be expecting.
4605 [Ronald.Tschalaer@psi.ch]
4607 *) Fix to mod_alias: translate_alias_redir is dealing with
4608 a URI, not a filename, so the check for drive letters for win32
4609 and emx is not necessary. [Dean Gaudet]
4611 *) WIN32: Allow .cmd as an executable extension.
4612 [Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146
4614 *) Make Apache header files, and some variables, C++ friendly.
4615 [Michael Anderson's <mka@redes.int.com.mx>]
4617 *) Child processes can now "signal" (by exiting with a status
4618 of APEXIT_CHILDFATAL) the parent process to abort and
4619 shutdown the server if the error in the child process was
4620 fatal enough. [Jim Jagielski]
4622 *) mod_autoindex's find_itme() was sensitive to MIME type case.
4623 [Jim Jagielski] PR#2112
4625 *) Make sure the referer_log and agent_log entries in the default httpd.conf
4626 file are also adjusted for the actual relative installation paths.
4627 [Ralf S. Engelschall] PR#2175
4629 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
4631 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
4634 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
4635 Additionally the checks for finding the vendor DSO library were moved
4636 from mod_so.c to Configure because first it needs $PLAT etc. and second
4637 mod_so already uses an abstraction layer and does not fiddle with the
4638 vendor functions itself.
4639 [Jens-Uwe Mager, Ralf S. Engelschall]
4641 *) PORT: Some optimization defines for NetBSD
4642 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
4644 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
4645 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
4647 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
4648 AIX variants should work fine, too. Even AIX 3.x should work). This is
4649 accomplished by using the free DSO emulation code from Jens-Uwe Mager
4650 which we put into a os/unix/os-dso-aix.c file.
4651 [Ralf S. Engelschall]
4653 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
4654 that we should use NET_SIZE_T == int but the include files force size_t.
4655 [Ralf S. Engelschall]
4657 *) Fix two bugs in select() handling in http_main.c.
4660 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
4661 is unset (as it is in situations like timeouts) where it is unclear
4662 whether errno is set or not. [Martin Kraemer]
4664 *) Just having APACI's localstatedir is too general and not enough for most
4665 of the systems. 1.3b6 again required manual APACI patches by package
4666 maintainers from RedHat and FreeBSD because for their filesystem layout a
4667 little bit more flexibility in configuring the paths is needed. Hence we
4668 provide three additional configure options (--runtimedir, --logfiledir,
4669 --proxycachedir) which now can be used for more granular adjustments if
4670 --localstatedir is not enough to fit the particular needs. As a nice
4671 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
4672 [Ralf S. Engelschall]
4674 *) Make the install root for "make install" in APACI's Makefile overrideable
4675 by package authors. This way we are even more friendly to package
4676 maintainers (especially Debian and RedHat) who build for the real prefix
4677 via "configure --prefix=/<real>" but use a different local prefix via
4678 "make root=/tmp/apache install" for rolling the package without bristling
4679 the target location on their system.
4680 [Ralf S. Engelschall]
4682 *) Workaround sed limitations in APACI's configure script by now
4683 substituting in chunks of 50 commands (because for instance HPUX's vendor
4684 sed has a limit of max. 98 commands)
4685 [Ralf S. Engelschall] PR#2136
4687 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
4688 [Ralf S. Engelschall] PR#2140
4690 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
4691 RENAMING process because they are defined as pre-processor macros instead
4692 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
4693 [Ralf S. Engelschall]
4695 *) Workaround braindead AWK's when generating ap_config.h: The split() and
4696 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
4697 [Ralf S. Engelschall] PR#2139
4699 *) Various bugfixes and cleanups for the APACI configure script:
4700 o fix IFS handling for _nested_ situation
4701 o fix Perl interpreter search: take first one found instead of last one
4702 o fix DSO consistency check
4703 o print error messages to stderr instead of stdout
4704 o add install-quiet for --shadow situation to Makefile stub
4705 o reduce complexity by avoiding sed-hacks for rule and module list loops
4706 [Ralf S. Engelschall]
4708 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
4710 *) Make sure the input field separator (IFS) shell variable is explicitly
4711 initialized correctly before _every_ `for' loop and also restored after
4712 the loops. [Ralf S. Engelschall]
4714 *) Make sure that "make install" doesn't overwrite the `mime.types' and
4715 `magic' files from an existing Apache installation. Because people often
4716 customize these for own MIME and content types.
4717 [Ralf S. Engelschall]
4719 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
4720 [Peter Galbavy, Ralf S. Engelschall] PR#2109
4722 *) Fix the path to the ScoreBoardFile in the install-config target, too.
4723 [Ralf S. Engelschall] PR#2105
4725 *) Let "configure" clear out the users parameters (provided as shell
4726 variables) to avoid side-effects in "src/Configure" when the user
4727 exported them (which is not needed, but some users do it).
4728 [Ralf S. Engelschall] PR#2101
4730 *) Provide backward compatibility from some old src/Configuration.tmpl
4731 parameter names to the canonical Autoconf-style shell variable names. For
4732 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
4733 but a hint message is displayed. [Ralf S. Engelschall]
4735 *) Make sure that "make install" doesn't overwrite the DocumentRoot and
4736 CGI scripts from an existing Apache installation.
4737 [Ralf S. Engelschall, Jim Jagielski] PR#2084
4739 *) Make `configure --compat' more "compatible" by first
4740 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
4741 second by making sure the "avoid-bristling-suffix" /apache is not
4742 appended to sysconfdir, datadir, localstatedir and includedir when
4743 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]
4745 *) NeXT required strdup() in support/logresolve.c
4746 [Francisco Tomei <fatomei@sandburg.unm.edu>] PR#2082
4748 *) AIX required sys/select.h in support/ab.c
4749 [Jens Schleusener <Jens.Schleusener@dlr.de>] PR#2081
4751 *) Fix the path to the MimeMagicFile in the install-config target, too.
4752 [Ralf S. Engelschall] PR#2089
4754 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
4756 *) If you start apache with the -S command line option it will dump
4757 out the parsed vhost settings. This is useful for folks trying
4758 to figure out what is wrong with their vhost configuration.
4759 (Other dumps may be added in the future.) [Dean Gaudet]
4761 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
4762 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
4765 *) Because /usr/local/apache is the default prefix the ``configure
4766 --compat'' option no longer has to set prefix, again. This way the
4767 --compat option honors a leading --prefix option. [Lars Eilebrecht]
4769 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
4770 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
4771 to avoid "discard const" warnings. [Ralf S. Engelschall]
4773 *) If a specific handler is set for a file yet the request still
4774 ends up being handled by the default handler, log an error
4775 message before handling it. This catches things such as trying
4776 to use SSIs without mod_include enabled. [Marc Slemko]
4778 *) Fix error logging for the startup case where ap_log_error() still uses
4779 stderr as the target. Now the default log level is honored here, too.
4780 [Ralf S. Engelschall]
4782 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
4783 long" errors when generating the MODULES entry for src/Makefile
4784 [Ben Hyde, Ralf S. Engelschall]
4786 *) Make sure src/Configure doesn't complain about the old directory
4787 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
4789 Changes with Apache 1.3b6
4791 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
4793 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
4794 interface via the similar but proprietary HP/UX shl_xxx-style system
4795 calls. [Ralf S. Engelschall]
4797 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
4798 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
4799 Make. [Ralf S. Engelschall]
4801 *) ++++ THE BIG SYMBOL RENAMING ++++
4802 To avoid symbol clashes with third-party code compiled into the server,
4803 we globally applied the prefix "ap_" to the following classes of
4805 - Apache provided general functions (e.g., ap_cpystrn)
4806 - Public API functions (e.g., palloc, bgets)
4807 - Private functions which we can't make static (because of
4808 cross-object usage) but should be (e.g., new_connection)
4809 For backward source compatibility a new header file named compat.h was
4810 created which provides defines for the old symbol names and can be used
4811 by third-party module authors.
4814 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
4815 problem under SVR4 is that there is no command flag to force the linker
4816 to export the global symbols of the httpd executable therewith they are
4817 available to the DSO's. Instead of problematic hacks like creating a
4818 dummy.so file (containing dummy references to all global symbols) the
4819 httpd binary is linked against, we use a clean trick stolen from Perl 5:
4820 Placing the Apache core code itself into a DSO library named libhttpd.so.
4821 This way the global symbols _HAVE_ to be exported and thus are available
4822 to any manually loaded DSO's under runtime. To reduce the impact to the
4823 user to null we go even further and create a stub httpd executable which
4824 automatically keeps track of the DSO library loading itself and thus
4825 hides the complete mechanism from the user. Although the generation of
4826 this DSO library is automatically triggered for platforms which
4827 essentially need it (mostly all SVR4-derivates) it can be also enabled
4828 manually via the Rule SHARED_CORE. This can be interesting in the future
4829 where we perhaps exploit this libhttpd.so mechanism for providing nifty
4830 features like graceful upgrades, or whatever.
4831 [Ralf S. Engelschall, Martin Kraemer]
4833 *) Build the libraries before building the rest of the tools. [Ben Hyde]
4835 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
4836 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
4837 conventions while "clean" removes only stuff created by "all" targets,
4838 "distclean" additionally removes the stuff from the configuration
4839 process. This way "make distclean" (hence the name) provides a fresh
4840 source tree as it was for distribution.
4841 [Ralf S. Engelschall]
4843 *) Allow top-level (APACI) Makefile to break on build errors
4844 the same way the src/ subtree Makefiles breaks on them by replacing the
4845 initial APACI sed-subdir-display-kludge with a more clean
4846 variable-passing-solution: variable SDP can optionally hold the subdir
4847 prefix which is consistently used for displaying the subdir movement.
4848 This way even the top-level Makefile can stop correctly on errors as the
4849 user expects. [Ralf S. Engelschall]
4851 *) Fixed ordering of argument checks for RewriteBase directive.
4852 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
4854 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
4855 indicating that a module is being compiled for dynamic loading. Also
4856 remove #define IS_MODULE from modules and add SHARED_MODULE define
4857 to the mak/dsp files. [Alexei Kosut]
4859 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
4860 since we are now logging APLOG_WARNING by default. [Roy Fielding]
4862 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
4864 *) Add documentation file and src/Configuration.tmpl entry for the
4865 experimental mod_mmap_static module. Because although it is and marked as
4866 an experimental one it is distributed and thus should be documented and
4867 prepared for configuration the same way as all others modules.
4868 [Ralf S. Engelschall]
4870 *) Add query (-q) option to apxs support tool to be able to manually query
4871 specific settings from apxs. This is needed for instance when you
4872 manually want to access Apache's header files and you need to assemble
4873 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
4874 [Ralf S. Engelschall]
4876 *) Now src/Configure uses a fallback strategy for the shared object support
4877 on platforms where no explicit information is available: If a Perl
4878 installation exists we ask it about its shared object support and if it's
4879 the dlopen-style one we shamelessly guess the compiler and linker flags
4880 for creating shared objects from Perls knowledge. Of course, the user is
4881 warning about what we are doing and informed that he should send us
4882 the guessed flags when they work. [Ralf S. Engelschall]
4884 *) Provide APACI --without-support option to be able to disable the build
4885 and installation of the support tools from the src/support/ area.
4886 Although its useful to have these installed per default we should provide
4887 a way to compile and install without them for backward-compatibility.
4888 [Ralf S. Engelschall]
4890 *) Add of the new APache eXtenSion (apxs) support tool for building and
4891 installing modules into an _already installed_ Apache package through the
4892 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
4893 this approach actually doesn't need the Apache source tree. The
4894 (APACI-installed) server package is enough, because this now includes the
4895 Apache C header files (PREFIX/include) and the new APXS tool
4896 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
4897 module authors to build their Apache modules _OUTSIDE_ the Apache source
4898 tree while avoiding them to fiddle around with the totally platform
4899 dependend way of compiling DSO files. The tool supports all ranges of
4900 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
4901 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
4902 on-the-fly generate a minimalistic Makefile and sample module for the
4903 first step to provide both a quick success event and to demonstrate the
4904 APXS mechanism to module authors. [Ralf S. Engelschall]
4906 *) Fix core dumps in use of CONNECT in proxy.
4907 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
4909 *) Modify the log directives in httpd.conf-dist files to use CustomLog
4910 so that users have examples of how CustomLog can be used.
4913 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
4914 the Apache distribution tree. Until Apache 1.3 there was no real
4915 out-of-the-box batch-capable build and installation procedure for the
4916 complete Apache package. This is now provided by a top-level "configure"
4917 script and a corresponding top-level "Makefile.tmpl" file. The goal is
4918 to provide a GNU Autoconf-style frontend which is capable to both drive
4919 the old src/Configure stuff in batch and additionally installs the
4920 package with a GNU-conforming directory layout. Any options from the old
4921 configuration scheme are available plus a lot of new options for flexibly
4922 customizing Apache. [Ralf S. Engelschall]
4924 *) The floating point ap_snprintf code wasn't threadsafe.
4925 Had to remove the HAVE_CVT macro in order to do threadsafe
4926 calling of the ?cvt() floating point routines. [Dean Gaudet]
4928 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
4930 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
4931 [Jim Jagielski] PR#1901
4933 *) BUG: Configure was using TCC and CC inconsistently. Make sure
4934 Configure knows which CC we are using. [Jim Jagielski]
4936 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
4937 was defined in a parent directory. [Lars Eilebrecht]
4939 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
4940 a generic printf-style routine that can call arbitrary output
4941 routines. Use this to replace http_bprintf.c. Add new routines
4942 psprintf(), pvsprintf() which allocate the exact amount of memory
4943 required for a string from a pool. Use psprintf() to clean up
4944 various bits of code which used ap_snprintf()/pstrdup().
4947 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
4948 ap_snprintf() has different semantics and formatting codes than
4949 snprintf(). [Dean Gaudet]
4951 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
4952 is necessary on at least Solaris where the /etc/rc?.d scripts
4953 are run with these signals ignored, and "SIG_IGN" settings are
4954 maintained across exec().
4955 [Rein Tollevik <reint@sys.sol.no>] PR#2009
4957 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
4958 used instead of lstat() and thus this flag didn't work as expected.
4959 [Rein Tollevik <reint@sys.sol.no>] PR#2010
4961 *) Fix the proxy pass-through feature of mod_rewrite for the case of
4962 existing QUERY_STRING now that mod_proxy was recently changed because of
4963 the new URL parsing stuff. [Ralf S. Engelschall]
4965 *) A few changes to scoreboard definitions which helps gcc generate
4966 better code. [Dean Gaudet]
4968 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
4969 be a signed bitfield. So mark a few bitfields as signed to
4970 ensure correct code. [Dean Gaudet]
4972 *) The default for HostnameLookups was changed to Off, but there
4973 was a problem and it wasn't taking effect. [Dean Gaudet]
4975 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
4978 *) After a SIGHUP the listening sockets in the parent weren't
4979 properly marked for closure on fork().
4980 [Jürgen Keil <jk@tools.de>] PR#2000
4982 *) Allow %2F in two situations: 1) it is in the query part of the URI,
4983 therefore not exposed to %2F -> '/' translations and 2) the request
4984 is a proxy request, so we're not dealing with a local resource anyway.
4985 Without this, the proxy would fail to work for any URL's with
4986 %2f in them (occurs quite often in
4987 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
4989 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
4991 *) Make the shared object compilation command more portable by avoiding
4992 the direct combination of `-c' & `-o' which is not honored by some
4993 compilers like UnixWare's cc. [Ralf S. Engelschall]
4995 *) WIN32: the proxy was creating filenames missing the last four
4996 characters. While this normally doesn't stop anything from
4997 working, it can result in extra collisions.
4998 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
5000 *) Now mod_proxy uses the response string (in addition to the response status
5001 code) from the already used FTP SIZE command to setup the Content-Length
5002 header if available. [Ralf S. Engelschall] PR#1183
5004 *) Reanimated the (still undocumented) proxy receive buffer size directive:
5005 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
5006 name was really too generic, added documentation for this directive to
5007 the mod_proxy.html and corrected the hyperlink to it in the
5008 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
5010 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
5011 faster [Martin Kraemer]
5013 *) Make Configure die when you give it an unknown command switch.
5016 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
5017 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
5018 and per default compiled support programs have manual pages - just to
5019 document our stuff a little bit more and to be able to do really
5020 Unix-like installations ;-) [Ralf S. Engelschall]
5022 *) Major cleanups to the Configure script to make it and its generated
5023 Makefiles again readable and maintainable: add SRCDIR option, removed
5024 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
5025 generated sections, consequently added Makefile headers with inheritance
5026 information, added subdir movement messages for easier following where
5027 the build process currently stays (more verbose then standard Make, less
5028 verbose than GNU make), same style to comments in the Configure script,
5029 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
5031 *) Add the new ApacheBench program "ab" to src/support/: This is derived
5032 from the ZeusBench benchmarking program and can be used to determine the
5033 response performance of an Apache installation. This version is
5034 officially licensed with Zeus Technology, Ltd. See the license agreement
5035 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
5036 [Ralf S. Engelschall]
5038 *) API: Various core functions that are definately not part of the API
5039 have been made static, and a few have been marked API_EXPORT. Still
5040 more have been marked CORE_EXPORT and are not intended for general
5041 use by modules. [Doug MacEachern, Dean Gaudet]
5043 *) mod_proxy was not clearing the Proxy-Connection header from
5044 requests; now it does. This did not violate any spec, however
5045 causes poor interactions when you are talking to remote proxies.
5046 [Marc Slemko] PR#1741
5048 *) Various cleanups to the command line interface and manual pages.
5049 [Ralf S. Engelschall]
5051 *) cfg_getline() was not properly handling lines that did not end
5052 with a line termination character. [Marc Slemko] PR#1869, 1909
5054 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
5056 *) Clean up some undocumented behavior of mod_setenvif related to
5057 "merging" two SetEnvIf directives when they match the same header
5058 and regex. Document that mod_setenvif will perform comparisons in
5059 the order they appear in the config file. Optimize mod_setenvif by
5060 doing more work at config time rather than at runtime.
5063 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
5064 to allow for modules to overrule them and to reduce redefinition
5065 warnings [Jim Jagielski]
5067 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
5070 *) Making the hard-coded cross-module function call mime_find_ct() (from
5071 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
5072 checking is really called even for proxy requests except for URLs with
5073 HTTP schemes (because there we can optimize by not running the type
5074 checking hooks due to the fact that the proxy gets the MIME Content-type
5075 from the remote host later). This change cleans up mod_mime by removing
5076 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
5077 especially unbundles mod_proxy and mod_mime. This way they both now can
5078 be compiled as shared objects and are no longer tied together.
5079 [Ralf S. Engelschall]
5081 *) util.c cleanup and speedup. [Dean Gaudet]
5083 *) API: Clarification, pstrndup() will always copy n bytes of the source
5084 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
5086 *) Mark module command_rec and handler_rec structures const so that they
5087 end up in the read-only data section (and are friendlier to systems
5088 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
5090 *) Add check to the "Port" directive to make sure the specified
5091 port is in the appropriate range. [Ben Hyde]
5093 *) Performance improvements to invoke_handler().
5094 [Dmitry Khrustalev <dima@bog.msu.su>]
5096 *) Added support for building shared objects even for library-style modules
5097 (which are built from more than one object file). This now provides the
5098 ability to build mod_proxy as a shared object module. Additionally
5099 modules like mod_example are now also supported for shared object
5100 building because the generated Makefiles now no longer assume there is at
5101 least one statically linked module. [Ralf S. Engelschall]
5103 *) API: Clarify usage of content_type, handler, content_encoding,
5104 content_language and content_languages fields in request_rec. They
5105 must always be lowercased; and the strings pointed to shouldn't
5106 be modified (you must copy them to modify them). Fix a few bugs
5107 related to this. [Dean Gaudet]
5109 *) API: Clarification: except for RAW_ARGS, all command handlers can
5110 treat the char * parameters as permanent, and modifiable. There
5111 is no need to pstrdup() them. Clean up some needless pstrdup().
5114 *) Now mod_so keeps track of which module shared objects with which names
5115 are loaded and thus avoids multiple loading and unloading and irritating
5116 error_log messages. [Ralf S. Engelschall]
5118 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
5119 environment variable in the apache core. But that tweaking interferes
5120 with mod_setenv. So don't tweak if the user has specified an explicit
5121 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
5123 *) rputs() did not calculate r->sent_bodyct properly.
5124 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
5126 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
5127 name, or left unset if this value is unavailable. Apache was setting
5128 it to the IP address when unavailable.
5129 [Tony Finch <fanf@demon.net>] PR#1925
5131 *) Various improvements to the configuration and build support for compiling
5132 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
5133 OSF1 support with GCC and vendor compilers was added. This way shared
5134 object support is now provided out-of-the-box for FreeBSD, Linux,
5135 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
5136 [Ralf S. Engelschall]
5138 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
5139 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
5140 and USE_OS2_SCOREBOARD. [Dean Gaudet]
5142 *) Fix one more special locking problem for RewriteMap programs in
5143 mod_rewrite: According to the documentation of flock(), "Locks are on
5144 files, not file descriptors. That is, file descriptors duplicated
5145 through dup(2) or fork(2) do not result in multiple instances of a lock,
5146 but rather multiple references to a single lock. If a process holding a
5147 lock on a file forks and the child explicitly unlocks the file, the
5148 parent will lose its lock.". To overcome this we have to make sure the
5149 RewriteLock file is opened _AFTER_ the childs were spawned which is now
5150 the case by opening it in the child_init instead of the module_init API
5151 hook. [Ralf S. Engelschall] PR#1029
5153 *) Change to Location and LocationMatch semantics. LocationMatch no
5154 longer lets a single slash match multiple adjacent slashes in the
5155 URL. This change is for consistency with RewriteRule and
5156 AliasMatch. Multiple slashes have meaning in URLs that they do
5157 not have in (some) filesystems. Location on the other hand can
5158 be considered a shorthand for a more complicated regex, and it
5159 does match multiple slashes with a single slash -- which is
5160 also consistent with the Alias directive.
5161 [Dean Gaudet] related PR#1440
5163 *) Fix bug with mod_mime_magic causing certain files, including files
5164 of length 0, to result in no response from the server.
5167 *) The Configure script now generates src/include/ap_config.h which
5168 contains the set of defines used when Apache is compiled on a platform.
5169 This file can then be included by external modules before including
5170 any Apache header files in case they are being built separately from
5171 Apache. Along with this change, a couple of minor changes were
5172 made to make Apache's #defines coexist peacefully with any autoconf
5173 defines an external module might have. [Rasmus Lerdorf]
5175 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
5176 but without any RewriteXXXXX directives. Here mod_rewrite is given no
5177 chance by the API to initialize its per-server configuration and thus
5178 receives the wrong one from the main server. This is now avoided by
5179 remembering the server together with the config structure while
5180 configuring and later assuming there is no config when we see a
5181 difference between the remembered server and the one calling us.
5182 [Ralf S. Engelschall] PR#1790
5184 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
5185 is automatically disabled under configure time when the dbm_xxx functions
5186 are not available. Second, two heavy source code errors in the DBM
5187 support code were fixed. This makes DBM RewriteMap's usable again after
5188 a long time of brokenness. [Ralf S. Engelschall] PR#1696
5190 *) Now all configuration files support Unix-style line-continuation via
5191 the trailing backslash ("\") character. This enables us to write down
5192 complex or just very long directives in a more readable way. The
5193 backslash character has to be really the last character before the
5194 newline and it has not been prefixed by another (escaping) backslash.

5206 *) WIN32: Preserve trailing slash in canonical path (and hence
5207 in PATH_INFO). [Paul Sutton, Ben Laurie]
5209 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
5210 depending on the rev of Solaris and what mixture of modules
5211 are in use. So it has been disabled, and Solaris is back to
5212 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
5213 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
5214 up static content only servers. Or it may fail unpredictably.
5215 [Dean Gaudet] PR#1779, 1854, 1904
5217 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
5220 *) API: Rewrite of absoluteURI handling, and in particular how
5221 absoluteURIs match vhosts. Unless a request is a proxy request, a
5222 "http://host" url is treated as if a similar "Host:" header had been
5223 supplied. This change was made to support future HTTP/1.x protocols
5224 which may require clients to send absoluteURIs for all requests.
5226 In order to achieve this change subtle changes were made to the API. In a
5227 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
5228 that the unmodified uri can be retrieved easily. r->proxyreq is not set
5229 by the core, modules must set it during the post_read_request or
5230 translate_names phase.
5232 Plus changes to the virtualhost test suite for absoluteURI testing.
5234 This fixes several bugs with the proxy proxying requests to vhosts
5235 managed by the same httpd.
5238 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
5239 code from mod_rewrite. The vhost matching is now performed by a
5240 globally available function matches_request_vhost(). [Dean Gaudet]

5256 *) API: A new source module main/util_uri.c; It contains a routine
5257 parse_uri_components() and friends which breaks a URI into its component
5258 parts. These parts are stored in a uri_components structure called
5259 parsed_uri within each request_rec, and are available to all modules.
5260 Additionally, an unparse routine is supplied which re-assembles the URI
5261 components back to an URI, optionally hiding the username:password@ part
5262 from ftp proxy requests, and other useful routines. Within the structure,
5263 you find on a ready-for-use basis:
5264 scheme; /* scheme ("http"/"ftp"/...) */
5265 hostinfo; /* combined [user[:password]@]host[:port] */
5266 user; /* user name, as in http://user:passwd@host:port/ */
5267 password; /* password, as in http://user:passwd@host:port/ */
5268 hostname; /* hostname from URI (or from Host: header) */
5269 port_str; /* port string (integer representation is in "port") */
5270 path; /* the request path (or "/" if only scheme://host was given) */
5271 query; /* Everything after a '?' in the path, if present */
5272 fragment; /* Trailing "#fragment" string, if present */
5273 This is meant to serve as the platform for *BIG* savings in
5274 code complexity for the proxy module (and maybe the vhost logic).
5277 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
5278 ${map:key}) available for all location where a string is created in
5279 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of

5281 possible expansions are consequently usable at all string creation
5282 locations. [Ralf S. Engelschall]

5308 *) Merged os/win32/mod_dll.c into modules/standard/mod_so.c to support
5309 dynamic loading on Win32 and Unix via the same module. [Paul Sutton]
5311 *) Now mod_rewrite no longer makes problematic assumptions on the characters
5312 a username can contain when trying to expand it via /etc/passwd.
5313 [Ralf S. Engelschall]
5315 *) The mod_setenvif BrowserMatch backwards compatibility command did not
5316 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
5318 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
5319 type but with a special post-processing for the looked-up value: It
5320 parses it into alternatives according to `|' chars and then only one
5321 particular alternative is chosen randomly (this is an essential
5322 functionality needed for balancing between backend-servers when using
5323 Apache as a Reverse Proxy. The looked up value here is a list of
5324 servers). Second, `int' with the built-in maps named `tolower' and
5325 `toupper' which can be used to map URL parts to a fixed case (this is an
5326 essential feature to fix the case of server names when doing mass
5327 virtual-hosting with the help of mod_rewrite instead of using
5328 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
5329 Jay Soffian <jay@cimedia.com>] PR#1631
5331 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
5332 This directive lets Apache adjust the URL in Location-headers on HTTP
5333 redirect responses sent by the remote server. This way the virtually
5334 mapped area is no longer left on redirects and thus by-passed which is
5335 especially essential when running Apache as a reverse proxy.
5336 [Ralf S. Engelschall]
5338 *) Hide Proxy-Authorization from CGI/SSI/etc just like Authorization is
5339 hidden. [Alvaro Martinez Echevarria]
5341 *) Apache will, when started with the -X (single process) debugging flag,
5342 honor the SIGINT or SIGQUIT signals again now. This capability got lost
5343 a while ago during OS/2 signal handling changes.
5345 *) [PORT] Work around the fact that NeXT runs on more than the
5346 m68k chips in mod_status [Scott Anguish and Timothy Luoma

5353 *) Use SA_RESETHAND or SA_ONESHOT when installing the coredump handlers.
5354 In particular the handlers could trigger themselves into an infinite
5355 loop if RLimitMem was used with a small amount of memory -- too small
5356 for the signal stack frame to be set up. [Dean Gaudet]

5370 *) mod_info would occasionally produce an unpaired <tt> in its
5371 output. Fixed. [Martin Kraemer]
5373 *) By default AIX binds a process (and it's children) to a single
5374 processor. httpd children now unbind themselves from that cpu
5375 and re-bind to one selected at random via bindprocessor()
5378 *) Linux 2.0 and above implement RLIMIT_AS, RLIMIT_DATA has almost no
5379 effect. Work around it by using RLIMIT_AS for the RLimitMEM
5380 directive. [Enrik Berkhan <enrik@inka.de>] PR#1816
5382 *) mod_mime_magic error message should indicate the filename when
5383 reads fail. ["M.D.Parker" <mdpc@netcom.com>] PR#1827
5385 *) Previously Apache would permit </Files> to end <FilesMatch> (and
5386 similary for Location and Directory), now this is diagnosed as an
5387 error. Improve error messages for mismatched sections (<Files>,
5388 <FilesMatch>, <Directory>, <DirectoryMatch>, ...).
5389 [Dean Gaudet, Martin Kraemer]
5391 *) <Files> is not permitted within <Location> (because of the
5392 semantic ordering). [Dean Gaudet] PR#379
5394 *) <Files> with wildcards was broken by the change in wildcard
5395 semantics (* does not match /). To fix this, <Files> now
5396 apply only to the basename of the request filename. This
5397 fixes some other inconsistencies in <Files> semantics

5405 *) Various errors from select() and accept() in child_main() would
5406 result in an infinite loop. It seems these two tickle kernel

5408 a generally bad scene. Now the child exits immediately,

5423 Changes with Apache 1.3b5
5425 *) Source file dependencies in Makefile.tmpl files throughout the

5429 *) Preserve the content encoding given by the AddEncoding directive
5430 when the client doesn't otherwise specify an encoding.
5431 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>]
5433 *) Sort out problems with canonical filename handling happening too late.
5434 [Dean Gaudet, Ben Laurie]
5436 Changes with Apache 1.3b4
5438 *) The module structure was modified to include a *dynamic_load_handle
5439 in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
5440 has been bumped accordingly. [Paul Sutton]
5442 *) All BrowserMatch directives mentioned in
5443 htdocs/manual/known_client_problems.html are in the default
5444 configuration files. [Lars Eilebrecht]
5446 *) MiNT port update. [Jan Paul Schmidt]
5448 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
5449 equivalent, similarly for x-compress and compress. Apache
5450 now ignores a leading x- when comparing encodings. It also
5451 preserves the encoding the client requests (for example if
5452 it requests x-gzip, then Apache will respond with x-gzip
5453 in the Content-Encoding header).
5454 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1772
5456 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
5458 *) Added mod_so module to support dynamic loading of modules on Unix
5459 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
5460 instead of AddModule in Configuration to build shared modules
5461 [Sameer Parekh, Paul Sutton]
5463 *) Minor cleanups to r->finfo handling in some modules.
5466 *) Abstract read()/write() to ap_read()/ap_write().
5467 Makes it easier to add other types of IO code such as SFIO.
5470 *) API: Generalize default_port manipulations to make support of
5471 different protocols easier. [Ben Laurie, Randy Terbush]
5473 *) There are many cases where users do not want Apache to form
5474 self-referential urls using the "canonical" ServerName and Port.
5475 The new UseCanonicalName directive (default on), if set to off
5476 will cause Apache to use the client-supplied hostname and port.
5477 API: Part of this change required a change to the construct_url()
5478 prototype; and the addition of get_server_name() and
5480 [Michael Douglass <mikedoug@texas.net>, Dean Gaudet]
5481 PR#315, 459, 485, 1433
5483 *) Yet another rearrangement of the source tree.. now all the common
5484 header files are in the src/include directory. The -Imain -Iap
5485 references in Makefiles have been changed to the simpler -Iinclude
5486 instead. In addition to simplifying the build a little bit, this
5487 also makes it clear when a module is referencing something in a
5488 other than kosher manner (e.g., the proxy including mod_mime.h).
5489 Module-private header files (the proxy, mod_mime, the regex library,
5490 and mod_rewrite) have not been moved to src/include; nor have
5491 the OS-abstraction files. [Ken Coar]
5493 *) Fix a bug where r->hostname didn't have the :port stripped
5494 from it. [Dean Gaudet]
5496 *) Tweaked the headers_out table size, and the subprocess_env
5497 table size guess in rename_original_environment(). Added
5498 MAKE_TABLE_PROFILE which can help discover make_table()
5499 calls that use too small an initial guess, see alloc.c.
5502 *) Options and AllowOverride weren't properly merging in the main
5503 server setting inside vhosts (only an issue when you have no
5504 <Directory> or other section containing an Options that affects
5505 a request). Options +foo or -foo in the main_server wouldn't
5506 affect the main_server's lookup defaults. [Dean Gaudet]
5508 *) Variable 'cwd' was being used pointlessly before being set.
5511 *) r->allowed handling cleaned up in the standard modules.
5514 *) Some case-sensitivity issues cleaned up to be consistent with
5515 RFC2068. [Dean Gaudet]
5517 *) SIGURG doesn't exist everywhere.
5518 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
5520 *) mod_unique_id was erroneously generating a second unique id when
5521 an internal redirect occured. Such redirects occur, for example,
5522 when processing a DirectoryIndex match. [Dean Gaudet]
5524 *) API: table_add, table_merge, and table_set include implicit pstrdup()
5525 of the key and value. But in many cases this is not required
5526 because the key/value is a constant, or the value has been built
5527 by pstrcat() or other similar means. New routines table_addn,
5528 table_mergen, and table_setn have been added to the API, these
5529 routines do not pstrdup() their arguments. The core code and
5530 standard modules were changed to take advantage of these routines.
5531 The resulting server is up to 20% faster in some situations.
5533 Note that it is easy to get code subtly wrong if you pass a key/value
5534 which is in a pool other than the pool of the table. The only
5535 safe thing to do is to pass key/values which are in the pool of
5536 the table, or in one of the ancestors of the pool of the table.
5537 i.e. if the table is part of a subrequest, a value from the main
5538 request's pool is OK since the subrequest pool is a sub_pool of the
5539 main request's pool (and therefore has a lifespan at most as long as
5540 the main pool). There is debugging code which can detect improper
5541 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
5542 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
5544 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
5545 which don't exist on disk more gracefully; handles vhosts properly.
5546 Update documentation to reflect the code -- if there's no
5547 MimeMagicFile directive then the module is not enabled.
5550 *) PORT: Some older *nix dialects cannot automatically start scripts
5551 which begin with a #! interpreter line (the shell starts the scripts
5552 appropriately on these platforms). Apache now supports starting of
5553 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
5554 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
5557 *) API: "typedef array_header table" removed from alloc.h, folks should
5558 have been writing to use table as if it were an opaque type, but even
5559 some standard modules got this wrong. By changing the definition
5560 to "typedef struct table table" module authors will receive compile
5561 time warnings that they're doing the wrong thing. This change
5562 facilitates future changes with more sophisticated table
5563 structures. Specifically, module authors should be using table_elts()
5564 to get access to an array_header * for the table. [Dean Gaudet]
5566 *) API: Renamed new_connection() to avoid namespace collision with LDAP
5567 library routines. [Ken Coar, Rasmus Lerdorf]
5569 *) WIN32: mod_speling is now available on the Win32 platform.
5572 *) For clarity the following compile time definition was changed:
5574 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
5576 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
5577 and not be a general notice that the OS has mmap(). Now the
5578 HAVE_MMAP/SHMGET #defines strictly are informational that the
5579 OS has that method of shared memory; the type to use for
5580 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
5581 and USE_SHMGET_SCOREBOARD). This allows outside modules to
5582 determine if shared memory is available and allows Apache
5583 to determine the best method to use for the scoreboard.
5586 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
5587 as do various earlier versions. It should be safe on all versions.
5588 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
5589 the slack code. A few other cleanups for Unixware.

5592 *) PORT: A/UX can handle single-listen accepts without mutex
5593 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
5595 *) When die() happens we need to eat any request body if one exists.
5596 Otherwise we can't continue with a keepalive session. This shows up
5597 as a POST problem with MSIE 4.0, typically against pages which are
5598 authenticated. [Roy Fielding] PR#1399
5600 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
5601 header will be passed to CGIs. This is generally a security hole, so
5602 it's not a default. [Marc Slemko] PR#549
5604 *) Fix Y2K problem with date printing in suexec log.

5607 *) WIN32 deserves a pid file. [Ben Hyde]
5609 *) suexec errors now include the errno/description. [Marc Slemko] PR#1543
5611 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
5612 The choice of flock vs. fcntl was made based on timings which showed that
5613 even on non-NFS, non-exported filesystems fcntl() was an order of
5614 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
5615 that single socket users will see no difference. [Dean Gaudet] PR#467
5617 *) "File does not exist" error message was erroneously including the
5618 errno. [Marc Slemko]
5620 *) Improve the warning message generated when a client drops the
5621 connection (hits stop button, etc.) during a send. [Roy Fielding]
5623 *) Defining GPROF will disable profiling in the parent and enable it
5624 in the children. If you're profiling under Linux this is pretty much
5625 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
5627 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.
5630 *) The NeXT cc (which is gcc hacked up) doesn't appear to support some
5631 gcc functionality. Work around it.

5634 *) Some linkers complain when .o files contain no functions.
5635 [Keith Severson <keith@sssd.navy.mil>] PR#1614
5637 *) Some const declarations in mod_imap.c that were added for debugging
5638 purposes caused some compilers heartburn without adding any
5639 significant value, so they've been removed. [Ken Coar]
5641 *) The src/main/*.h header files have had #ifndef wrappers added to
5642 insulate them against duplicate calls if they get included through
5643 multiple paths (e.g., in .c files as well as other .h files).
5646 *) The libap routines now have a header file for their prototypes,
5647 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
5649 *) mod_autoindex with a plaintext header file would emit the <PRE>
5650 start-tag before the HTML preamble, rather than after the preamble
5651 but before the header file contents. [John Van Essen <jve@gamers.org>]
5654 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
5655 only an issue on systems without a MAXDNAME define or where
5656 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
5658 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
5659 is used to read various types of files such as htaccess and
5660 htpasswd files. [Marc Slemko]
5662 *) SECURITY: Ensure that the buffer returned by ht_time is always
5663 properly null terminated. [Marc Slemko]
5665 *) The "Connection" header could be sent back with multiple "close"
5666 tokens. Not an error, but a waste.
5667 [Ronald.Tschalaer@psi.ch] PR#1683
5669 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
5670 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
5672 *) "basic" auth needs a case-insensitive comparison.
5673 [Ronald.Tschalaer@psi.ch] PR#1666
5675 *) For maximum portability, the environment passed to CGIs should
5676 only contain variables whose names match the regex
5677 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
5678 underscores over any character outside the regex. This
5679 affects HTTP_* variables, in a way that should be backward
5680 compatible for all the standard headers; and affects variables
5681 set with SetEnv/BrowserMatch and similar directives.
5684 *) mod_speling returned incorrect HREF's when an ambigous match
5685 was found. Noticed by <robinton@amtrash.comlink.de> (Soeren Ziehe)

5692 *) PORT: Fix problem killing children when terminating. Allow ^C
5693 to shut down the server. [Brian Havard]

5696 no need to do it before calling. Clean up a few cases.
5697 [Marc Slemko, Dean Gaudet]
5699 *) new -C and -c command line arguments

5720 *) SECURITY: Numerous changes to mod_imap in a general cleanup
5721 including fixing a possible buffer overflow. [Dean Gaudet]
5723 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful
5724 (connections are not dropped). Code can handle graceful restarts
5725 (but there is as yet no way to signal this to Apache). Various
5726 other cleanups. [Paul Sutton]
5728 *) The aplog_error changes specific to 1.3 introduced a buffer
5729 overrun in the (now legacy) log_printf function. Fixed.
5732 *) mod_digest didn't properly deal with proxy authentication. It

5765 *) non-WIN32 was missing destroy_mutex definition. [Ben Hyde]
5767 *) send_fd_length() did not calculate total_bytes_sent properly.
5768 [Ben Reser <breser@regnow.com>] PR#1366
5770 *) The bputc() macro was not properly integrated with the chunking
5771 code; in many cases modules using bputc() could cause completely
5772 bogus chunked output. (Typically this will show up as problems
5773 with Internet Explorer 4.0 reading a page, but other browsers
5774 having no problem.) [Dean Gaudet]
5776 *) Create LARGE_WRITE_THRESHOLD define which determines how many
5777 bytes have to be supplied to bwrite() before it will consider
5778 doing a writev() to assemble multiple buffers in one system
5779 call. This is critical for modules such as mod_include,
5780 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
5781 strings in some cases. The result would be extra effort
5782 setting up writev(), and in many cases extra effort building
5783 chunks. The default is 31, it can be overriden at compile
5786 *) Move the gid switching code into the child so that log files

5849 *) WIN32: Cure file leak in CGIs. [Peter Tillemans <pti@net4all.be>] PR#1523
5851 *) proxy_ftp: the directory listings generated by the proxy ftp module
5852 now have a title in which the path components are clickable and allow
5853 quick navigation to the clicked-on directory on the currently listed
5854 ftp server. This also fixes a bug where the ".." directory links would
5855 sometimes refer to the wrong directory. [Martin Kraemer]

5870 *) WIN32: Work around brain-damaged spawn calls that can't deal
5871 with spaces and slashes. [Ben Laurie]
5873 *) WIN32: Fix the code so CGIs can use socket calls on Windows.
5874 The problem was that certain undocumented environment variables
5875 needed for sockets to work under Win32 were not being passed.

5878 *) Add a "-V" command line flag to the httpd binary. This
5879 flag shows some of the defines that Apache was compiled with.
5880 It is useful for debugging purposes. [Martin Kraemer]
5882 *) Start separating the ap_*() routines into their own library, so they
5883 can be used by items in src/support among other things.

5886 *) Give a more informative error when no AuthType is set.
5889 *) Remove strtoul() use from mod_proxy because it isn't available
5890 on all platforms. [Marc Slemko] PR#1214
5892 *) WIN32: Some Win32 systems terminated all responses after 16 kB.
5893 This turns out to be a bug in Winsock - select() doesn't always
5894 return the correct status. [Ben Laurie]
5896 *) Directives owned by http_core can now use the new check_cmd_context()
5897 routine to ensure that they're not being used within a container
5898 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
5900 *) PORT: Recent changes made it necessary to add explicit prototype
5901 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
5903 *) It was necessary to distinguish between resources which are
5904 allocated in the parent, for cleanup in the parent, and resources
5905 which are allocated in each child, for cleanup in each child.
5906 A new pool was created which is passed to the module child_init
5907 and child_exit functions; modules are free to register per-child
5908 cleanups there. This fixes a bug with reliable piped logs.
5911 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
5912 unless it was also doing FancyIndexes, but it displayed the
5913 HeaderName file at the top under all circumstances. It now shows
5914 the ReadmeName file for simple indices, too, as it should.
5917 *) http_core was mmap()ing even in cases where it wasn't going to
5918 read the file. [Ben Hyde <bhyde@gensym.com>]
5920 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
5921 Now the rewriting engine (the heart of mod_rewrite) is organized more
5922 straight-forward, first time well documented and reduced to the really
5923 essential parts. All redundant cases were stripped off and processing now
5924 is the same for both per-server and per-directory context with only a
5925 minimum difference (the prefix stripping in per-dir context). As a
5926 side-effect some subtle restrictions and two recently discovered problems
5927 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
5928 context and restrictions on the substitution URL on redirects.
5929 Additionally some minor source cleanups were done.

6081 name of the virtual host (listed first in the log records by "%v").
6084 Changes with Apache 1.3b2 (there is no 1.3b1)
6086 *) TestCompile was not passing $LIBS [Dean Gaudet]
6088 *) Makefile.tmpl was not using $CFLAGS in the link phase.
6091 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
6092 rudimentary memory debugger which can be used on live servers with
6093 low impact -- it sets all allocated and freed memory bytes to 0xa5.
6094 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
6095 and free() for each object. This is far more expensive and should
6096 only be used for testing with tools such as Electric Fence and
6097 Purify. See main/alloc.c for more details. [Dean Gaudet]
6099 *) Configure uses a sh trap and didn't set its exitcode properly.
6100 [Dean Gaudet] PR#1159
6102 *) Yet another vhost revamp. Add the NameVirtualHost directive which
6103 explicitly lists the ip:port pairs that are to be used for name-vhosts.
6104 From a given ip:port, regardless what the Host: header is, you can
6105 only reach the vhosts defined on that ip:port. The precedence of
6106 vhosts was reversed to match other precedences in the config --
6107 the earlier vhosts override the later vhosts. All vhost matching was
6108 moved into http_vhost.[ch]. [Dean Gaudet]
6110 *) ap_inline can be used to force inlining. GNUC __attribute__() can
6111 be used for whatever reason is appropriate (i.e. format() warnings
6112 for printf style functions). Both are enabled only with
6113 gcc >= 2.7.x (so that we have fewer support issues with older
6114 versions). [Dean Gaudet]
6116 *) Fix support for Proxy Authentication (we were testing the response
6117 status too early). [Marc Slemko]
6119 *) CoreDumpDirectory directive directs where the core file is
6120 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
6121 received. [Marc Slemko, Dean Gaudet]
6123 *) PORT: Support for Atari MINT.
6124 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
6126 *) When booting, apache will now detach itself from stdin, stdout,
6127 and stderr. stderr will not be detached until after the config
6128 files have been read so you will be able to see initial error
6129 messages. After that all errors are logged in the error_log.
6130 This makes it more convenient to start apache via rsh, ssh,
6131 or crontabs. [Dean Gaudet] PR#523
6133 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
6134 Also removed the auto-generated link to www.apache.org that was the
6135 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
6137 *) send_fb would not detect aborted connections in some situations.
6140 *) mod_include would use uninitialized data when parsing certain
6141 expressions involving && and ||. [Brian Slesinsky] PR#1139
6143 *) mod_imap should only handle GET methods. [Jay Bloodworth]
6145 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
6147 *) mod_autoindex improperly counted &escapes; as more than one
6148 character in the description. It also improperly truncated
6149 descriptions that were exactly the maximum length.
6152 *) RedirectMatch was not properly escaping the result (PR#1155). Also
6153 "RedirectMatch /advertiser/(.*) $1" is now permitted.
6156 *) mod_include now uses symbolic names to check for request success
6157 and return HTTP errors, and correctly handles all types of
6158 redirections (previously it only did temporary redirect correctly).
6159 [Ken Coar, Roy Fielding]
6161 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
6162 r->filename. Since those two are meant to be in sync with each other
6163 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
6165 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
6166 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]
6168 *) Inetd mode (which is buggy) uses timeouts without having setup the
6169 jmpbuffer. [Dean Gaudet] PR#1064
6171 *) Work around problem under Linux where a child will start looping
6172 reporting a select error over and over.
6173 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
6175 *) Fixed error in proxy_util.c when looping through multiple host IP
6176 addresses. [Lars Eilebrecht] PR#974
6178 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
6179 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
6180 bytes before writing, but it will never split a log entry across a
6181 buffer boundary. [Dean Gaudet]
6183 *) API: the short_score record has been split into two pieces, one which
6184 the parent writes on, and one which the child writes on. As part of
6185 this change the get_scoreboard_info() function was removed, and
6186 scoreboard_image was exported. This change fixes a race condition
6187 in file based scoreboard systems, and speeds up changes involving the
6188 scoreboard in earlier 1.3 development. [Dean Gaudet]
6190 *) API: New register_other_child() API (see http_main.h) which allows
6191 modules to register children with the parent for maintenance. It
6192 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
6194 *) API: New piped_log API (see http_log.h) which implements piped logs,
6195 and will use register_other_child to implement reliable piped logs
6196 when it is available. The reliable piped logs part can be disabled
6197 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
6198 logs is only available on Unix. [Dean Gaudet]
6200 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
6201 meets_conditions(). This allows conditional HTTP selection to be
6202 handled separately from the storing of the header fields, and provides
6203 the ability for CGIs to set their own ETags for conditional checking.
6204 [Ken Coar, Roy Fielding] PR#895
6206 *) Changes to mod_log_config to allow naming of format strings.
6207 Format nicknames are defined with "LogFormat fmt nickname", and can
6208 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
6211 *) New module, "mod_speling", which can help find files even when
6212 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
6214 *) API: New function child_terminate() triggers the child process to
6215 exit, while allowing the child finish what it needs to for the
6216 current request first.
6217 [Doug MacEachern, Alexei Kosut]
6219 *) Windows now defaults to using full status reports with mod_status.
6220 [Alexei Kosut] PR #1094
6222 *) *Really* disable all mod_rewrite operations if the engine is off.
6223 Some things (like RewriteMaps) were checked/performed even if they
6224 weren't supposed to be. [Ken Coar] PR #991
6226 *) Implement a new timer scheme which eliminates the need to call alarm() all
6227 the time. Instead a counter in the scoreboard for each child is used to
6228 show when the child has made forward progress. The parent samples this
6229 counter every scoreboard maintenance cycle, and issues SIGALRM if no
6230 progress has been made in the timeout period. This reduces the static
6231 request best-case syscall count to 22 from 29. This scheme is only
6232 used by systems with memory-based scoreboards. [Dean Gaudet]
6234 *) The proxy now properly handles CONNECT requests which are sent
6235 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
6237 *) A script called apachectl has been added to the support
6238 directory. This script allows you to do things such as
6239 "apachectl start" and "apachectl restart" from the command
6242 *) Modules and core routines are now put into libraries, which
6243 simplifies the link line tremendously (among other advantages).
6246 *) Some of the MD5 names defined in Apache have been renamed to have
6247 an `ap_' prefix to avoid conflicts with routines supplied by
6248 external libraries. [Ken Coar]
6250 *) Removal of mod_auth_msql.c from the distribution. There are many
6251 other options for databases today. Rather than offer one option,
6252 offer none at this time. mod_auth_msql and other SQL database
6253 authentication modules can be found at the Apache Module Registry.
6254 http://modules.apache.org/ It would be nice to offer a generic
6255 mod_auth_sql option in the near future.
6257 *) PORT: BeOS support added [Alexei Kosut]
6259 *) Configure no longer accepts the -make option, since it creates
6260 Makefile on the fly based on Makefile.tmpl and Configuration.
6262 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
6263 of forcibly killing off all its processes and exiting without
6264 cleaning up. [Alexei Kosut]
6266 *) API: A new field in the request_rec, r->mtime, has been added to
6267 avoid gratuitous parsing of date strings. It is intended to hold
6268 the last-modified date of the resource (if applicable). An
6269 update_mtime() routine has also been added to advance it if
6270 appropriate. [Roy Fielding, Ken Coar]
6272 *) SECURITY: If a htaccess file can not be read due to bad permissions,
6273 deny access to the directory with a HTTP_FORBIDDEN. The previous
6274 behavior was to ignore the htaccess file if it could not be read.
6275 This change may make some setups with unreadable htaccess files
6276 stop working. [Marc Slemko] PR#817
6278 *) Add aplog_error() providing a mechanism to define levels of
6279 verbosity to the server error logging. This addition also provides
6280 the ability to log errors using syslogd. Error logging is configurable
6281 on a per-server basis using the LogLevel directive. Conversion
6282 of log_*() in progress. [Randy Terbush]
6284 *) Further enhance aplog_error() to not log filename, line number, and
6285 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
6287 *) WIN32: Canonicalise filenames under Win32. Short filenames are
6288 converted to long ones. Backslashes are converted to forward
6289 slashes. Case is converted to lower. Parts of URLs that do not
6290 correspond to files are left completely alone. [Ben Laurie]
6292 *) PORT: 2 new OSs added to the list of ports:
6293 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
6294 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
6296 *) Add the server version (SERVER_VERSION macro) to the "server
6297 configured and running" entry in the error_log. Also build an
6298 object file at link-time that contains the current time
6299 (SERVER_BUILT global const char[]), and include that in the
6302 *) Set r->headers_out when sending responses from the proxy.
6303 This fixes things such as the logging of headers sent from
6304 the proxy. [Marc Slemko] PR#659
6306 *) support/httpd_monitor is no longer distributed because the
6307 scoreboard should not be file based if at all possible. Use
6308 mod_status to see current server snapshot.
6310 *) (set_file_slot): New function, allowing auth directives to be
6311 independent of the server root, so the server documents can be
6312 moved to a different directory or machine more easily.
6313 [David J. MacKenzie]
6315 *) If no TransferLog is given explicitly, decline
6316 to log. This supports coexistence with other logging modules,
6317 such as the custom one that UUNET uses. [David J. MacKenzie]
6319 *) Check for titles in server-parsed HTML files.
6320 Ignore leading newlines and returns in titles. The old behavior
6321 of replacing a newline after <title> with a space causes the
6322 title to be misaligned in the listing. [David J. MacKenzie]
6324 *) Change mod_cern_meta to be configurable on a per-directory basis.
6325 [David J. MacKenzie]
6327 *) Add 'Include' directive to allow inclusion of configuration
6328 files within configuration files. [Randy Terbush]
6330 *) Proxy errors on connect() are logged to the error_log (nothing
6331 new); now they include the IP address and port that failed
6332 (*that's* new). [Ken Coar, Marc Slemko] PR#352
6334 *) Various architectures now define USE_MMAP_FILES which causes
6335 the server to use mmap() for static files. There are two
6336 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
6337 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
6338 number of bytes written in one cycle from a single mmap()d object,
6339 default 32768). [Dean Gaudet]
6341 *) API: Added post_read_request API phase which is run right after reading
6342 the request from a client, or right after an internal redirect. It is
6343 useful for modules setting environment variables that depend only on
6344 the headers/contents of the request. It does not run during subrequests
6345 because subrequests inherit pretty much everything from the main
6346 request. [Dean Gaudet]
6348 *) Added mod_unique_id which is used to generate a unique identifier for
6349 each hit, available in the environment variable UNIQUE_ID.
6352 *) init_modules is now called after the error logs have been opened. This
6353 allows modules to emit information messages into the error logs.
6356 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
6357 information for case where proxy module is not available. [Marc Slemko]
6359 *) PORT: Apache has need for mutexes to serialize its children around
6360 accept. In prior versions either fcntl file locking or flock file
6361 locking were used. The method is chosen by the definition of
6362 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
6363 and FLOCK for flock(). New options have been added:
6364 - SYSVSEM to use System V style semaphores
6365 - PTHREAD to use POSIX threads (appears to work on Solaris only)
6366 - USLOCK to use IRIX uslock
6367 Based on timing various techniques, the following changes were made
6369 - Linux 2.x uses flock instead of fcntl
6370 - Solaris 2.x uses pthreads
6371 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
6372 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
6373 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
6374 Martijn Koster <m.koster@pobox.com>]
6376 *) PORT: The semantics of accept/select make it very desirable to use
6377 mutexes to serialize accept when multiple Listens are in use. But
6378 in the case where only a single socket is open it is sometimes
6379 redundant to serialize accept(). Not all unixes do a good job with
6380 potentially dozens of children blocked on accept() on the same
6381 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
6382 the server will avoid serialization when listening on only one socket,
6383 and use serialization when listening on multiple sockets.
6384 [Dean Gaudet] PR#467
6386 *) Configure changes: TestLib replaced by TestCompile, which has
6387 some additional capability (such as doing a sanity check of
6388 the compiler and flags selected); the version of Solaris is now
6389 available via the #define value of SOLARIS2; IRIX n32bit libs
6390 now supported and selectable by new Configuration Rule: IRIXN32;
6391 We no longer default to -O2 optimization. [Jim Jagielski]
6393 *) Updated Configure: Configuration now uses AddModule to specify
6394 module source or binary file location, relative to src directory.
6395 Modules can be dropped into modules/extra, or in their own
6396 directory, and modules can come with a Makefile or Configure can
6397 create one. Modules can add compiler or library information to
6398 generated Makefiles. [Paul Sutton]
6400 *) Source core re-organisation: distributed modules are now in
6401 modules/standard. All other source code is in main. OS-specific
6402 code is in os/{unix,emx,win32} directories. [Paul Sutton]
6404 *) mod_browser has been removed, since it's replaced by mod_setenvif.
6407 *) Fix another long-standing bug in sub_req_lookup_file where it would
6408 happily skip past access checks on subdirectories looked up with
6409 relative paths. (It's used by mod_dir, mod_negotiation,
6410 and mod_include.) [Dean Gaudet]
6412 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
6413 N is the number of <Directory> sections, and M is the number of
6414 components in the filename of an object.
6416 To achieve this optimization the following config changes were made:
6417 - Wildcards (* and ?, not the regex forms) in <Directory>s,
6418 <Files>s, and <Location>s now treat a slash as a special
6419 character. For example "/home/*/public_html" previously would
6420 match "/home/a/andrew/public_html", now it only matches things
6421 like "/home/bob/public_html". This mimics /bin/sh behaviour.
6422 - It's possible now to use [] wildcarding in <Directory>, <Files>
6424 - Regex <Directory>s are applied after all non-regex <Directory>s.
6428 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
6429 and corrupted paths. [Dean Gaudet]
6431 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
6432 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
6433 be accessed now via backreferences $1..$9 in RewriteConds test-against
6434 strings in addition to RewriteRules subst string. Second the grouped
6435 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
6436 via backreferences %1..%9 both in following RewriteCond test-against
6437 strings and RewriteRules subst string. This provides maximum flexibility
6438 through the use of backreferences.
6439 Additionally the rewriting engine was cleaned up by putting common
6440 code to the new expand_backrefs_inbuffer() function.
6441 [Ralf S. Engelschall]
6443 *) When merging the main server's <Directory> and <Location> sections into
6444 a vhost, put the main server's first and the vhost's second. Otherwise
6445 the vhost can't override the main server. [Dean Gaudet] PR#717
6447 *) The <Directory> code would merge and re-merge the same section after
6448 a match was found, possibly causing problems with some modules.
6451 *) ip-based vhosts are stored and queried using a hashing function, which
6452 has been shown to improve performance on servers with many ip-vhosts.
6453 Some other changes had to be made to accommodate this:
6454 - the * address for vhosts now behaves like _default_
6455 - the matching process now is:
6456 - match an ip-vhost directly via hash (possibly matches main
6458 - if that fails, just pretend it matched the main server
6459 - if so far only the main server has been matched, perform
6460 name-based lookups (ServerName, ServerAlias, ServerPath)
6461 *only on name-based vhosts*
6462 - if they fail, look for _default_ vhosts
6463 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
6465 *) dbmmanage overhaul:
6466 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
6467 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
6468 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
6469 - provide better seed for rand
6470 - prompt for password as per getpass(3) (turn off echo, read from
6472 - use "newstyle" crypt based on $Config{osname} ($^O)
6473 - will not add a user if already in database, use new `update' command
6475 - added `check' command to check a users' password
6476 - added `import' command to convert existing password text-files or
6477 dbm files exported with `view'
6478 - more descriptive usage, general cleanup, 'use strict' clean, etc.
6481 *) Added psocket() which is a pool form of socket(), various places within
6482 the proxy weren't properly blocking alarms while registering the cleanup
6483 for its sockets. bclose() now uses pclose() and pclosesocket(). There
6484 was a bug where the client socket was being close()d twice due a still
6485 registered cleanup. [Dean Gaudet]
6487 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
6490 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
6491 [Jason Venner <jason@idiom.com>] PR#667
6493 *) Enable ``=""'' for RewriteCond directives to match against
6494 the empty string. This is the preferred way instead of ``^$''.
6495 [Ralf S. Engelschall]
6497 *) Fixed an infinite loop in mod_imap for references above the server root
6498 [Dean Gaudet] PR#748
6500 *) mod_proxy now has a ReceiveBufferSize directive, similar to
6501 SendBufferSize, so that the TCP window can be set appropriately
6502 for LFNs. [Phillip A. Prindeville]
6504 *) mod_browser has been replaced by the more general mod_setenvif
6505 (courtesy of Paul Sutton). BrowserMatch* directives are still
6506 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
6507 UnSetEnvIfZero directives. [Ken Coar]
6509 *) "HostnameLookups double" forces double-reverse DNS to succeed in
6510 order for remote_host to be set (for logging, or for the env var
6511 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
6514 *) mod_access overhaul:
6515 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
6516 and cidr syntax (i.e. 10.1.0.0/16). PR#762
6517 - Critical path was sped up by pre-computing a few things at config time.
6518 - The undocumented syntax "allow user-agents" was removed,
6519 the replacement is "allow from env=foobar" combined with mod_browser.
6520 - When used with hostnames it now forces a double-reverse lookup
6521 no matter what the directory settings are. This double-reverse
6522 doesn't affect any of the other routines that use the remote
6523 hostname. In particular it's still passed to CGIs and the log
6524 without the double-reverse check. Related PR#860.
6527 *) When a large bwrite() occurs (larger than the internal buffer size),
6528 while there is already something in the buffer, apache will combine
6529 the large write and the buffer into a single writev(). (This is
6530 in anticipation of using mmap() for reading files.)
6533 *) In obscure cases where a partial socket write occurred while chunking,
6534 Apache would omit the chunk header/footer on the next block. Cleaned
6535 up other bugs/inconsistencies in error conditions in buff.c. Fixed
6536 a bug where a long pause in DNS lookups could cause the last packet
6537 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
6539 *) API: Added child_exit function to module structure. This is called
6540 once per "heavy-weight process" just before a server child exit()'s
6541 e.g. when max_requests_per_child is reached, etc.
6542 [Doug MacEachern, Dean Gaudet]
6544 *) mod_include cleanup showed that handle_else was being used to handle
6545 endif. It didn't cause problems, but it was cleaned up too.
6548 *) mod_cern_meta would attempt to find meta files for the directory itself
6549 in some cases, but not in others. It now avoids it in all cases.
6552 *) mod_mime_magic would core dump if there was a decompression error.
6553 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
6555 *) PORT: some variants of DGUX require -lsocket -lnsl
6556 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
6558 *) mod_autoindex now allows sorting of FancyIndexed directory listings
6559 by the various fields (name, size, et cetera), either in ascending
6560 or descending order. Just click on the column header. [Ken Coar]
6562 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
6563 CPUs like the Alpha. Apache still stores ints in pointers, but that's
6564 the relatively safe direction. [Dean Gaudet] PR#344
6566 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
6567 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
6569 *) child_main avoids an unneeded call to select() when there is only one
6570 listening socket. [Dean Gaudet]
6572 *) In the event that the server is starved for idle servers it will
6573 spawn 1, then 2, then 4, ..., then 32 servers each second,
6574 doubling each second. It'll also give a warning in the errorlog
6575 since the most common reason for this is a poor StartServers
6576 setting. The define MAX_SPAWN_RATE can be used to raise/lower
6577 the maximum. [Dean Gaudet]
6579 *) Apache now provides an effectively unbuffered connection for
6580 CGI scripts. This means that data will be sent to the client
6581 as soon as the CGI pauses or stops output; previously, Apache would
6582 buffer the output up to a fixed buffer size before sending, which
6583 could result in the user viewing an empty page until the CGI finished
6584 or output a complete buffer. It is no longer necessary to use an
6585 "nph-" CGI to get unbuffered output. Given that most CGIs are written
6586 in a language that by default does buffering (e.g. perl) this
6587 shouldn't have a detrimental effect on performance.
6589 "nph-" CGIs, which formerly provided a direct socket to the client
6590 without any server post-processing, were not fully compatible with
6591 HTTP/1.1 or SSL support. As such they would have had to implement
6592 the transport details, such as encryption or chunking, in order
6593 to work properly in certain situations. Now, the only difference
6594 between nph and non-nph scripts is "non-parsed headers".
6595 [Dean Gaudet, Sameer Parekh, Roy Fielding]
6597 *) If a BUFF is switched from buffered to unbuffered reading the first
6598 bread() will return whatever remained in the buffer prior to the
6599 switch. [Dean Gaudet]
6601 Changes with Apache 1.3a1
6603 *) Added another Configure helper script: TestLib. It determines
6604 if a specified library exists. [Jim Jagielski]
6606 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
6607 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
6610 *) PORT: Some architectures use size_t for various lengths in network
6611 functions such as accept(), and getsockname(). The definition
6612 NET_SIZE_T is used to control this. [Dean Gaudet]
6614 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
6615 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
6616 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
6618 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
6619 [Igor N Kovalenko <infoh@mail.wplus.net>]
6621 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
6622 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
6623 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
6624 [Dean Gaudet] related PR#875
6626 *) API: Correct child_init() slot declaration from int to void, to
6627 match the init() declaration. Update mod_example to use the new
6630 *) added transport handle slot (t_handle) to the BUFF structure
6633 *) get_client_block() returns wrong length if policy is
6634 REQUEST_CHUNKED_DECHUNK.
6635 [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815
6637 *) Support the image map format of FrontPage. For example:

6641 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
6642 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
6644 *) AddModuleInfo directive for mod_info which allows you to annotate
6645 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
6647 *) Added NoProxy directive to avoid using ProxyRemote for selected
6648 addresses. Added ProxyDomain directive to cause unqualified
6649 names to be qualified by redirection.
6650 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
6652 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
6653 header to the remote host in the proxy. [Sameer Parekh and
6656 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
6657 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
6658 URLs, fixed rewritelog(), fixed forced response code handling on
6659 redirects from within .htaccess files, disabled pipe locking under
6660 braindead SunOS 4.1.x, allow env variables to be set even on rules with
6661 no substitution, bugfixed situations where HostnameLookups is off, made
6662 mod_rewrite more thread-safe for NT port and fixed problem when creating
6663 an empty query string via "xxx?".
6664 This update also removes the copyright of Ralf S. Engelschall,
6665 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
6666 exclusively copyrighted by the Apache Group now. This happened because
6667 the author now has gifted mod_rewrite exclusively to the Apache Group and
6668 no longer maintains an external version.
6669 [Ralf S. Engelschall]
6671 *) API: Added child_init function to module structure. This is called
6672 once per "heavy-weight process" before any requests are handled.
6673 See http_config.h for more details. [Dean Gaudet]
6675 *) Anonymous_LogEmail was logging on each subrequest.
6676 [Dean Gaudet] PR#421, 868
6678 *) API: Added is_initial_req() which tests if the request being
6679 processed is the initial request, or a subrequest.
6682 *) Extended SSI (mod_include) now handles additional relops for
6683 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
6685 *) Configure fixed to correctly propagate user-selected options and
6686 settings (such as CC and OPTIM) to Makefiles other than
6687 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
6689 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
6690 directory indices to start with the contents of the HeaderName file
6691 if there is one. If there isn't one, the behaviour is unchanged.
6692 [Ken Coar, Roy Fielding, Andrey A. Chernov]
6694 *) WIN32: Modules can now be dynamically loaded DLLs using the
6695 LoadModule/LoadFile directives. Note that module DLLs must be
6696 compiled with the multithreaded DLL version of the runtime library.
6697 [Alexei Kosut and Ben Laurie]
6699 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
6700 This allows the admin to completely remove automatic indexing
6701 from the server, while still supporting the basic functions of
6702 trailing-slash redirects and DirectoryIndex files. Note that if
6703 you're carrying over an old Configuration file and you use directory
6704 indexing then you'll want to add:
6706 Module autoindex_module mod_autoindex.o
6708 before mod_dir in your Configuration. [Dean Gaudet]
6710 *) popendir/pclosedir created to properly protect directory scanning.
6711 [Dean Gaudet] PR#525
6713 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
6714 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
6715 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
6718 *) The AccessFileName directive can now take more than one filename.
6719 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
6721 *) The new mod_mime_magic can be used to "magically" determine the type
6722 of a file if the extension is unknown. Based on the unix file(1)
6723 command. [Ian Kluft <ikluft@cisco.com>]
6725 *) We now determine and display the time spent processing a
6726 request if desired. [Jim Jagielski]
6728 *) mod_status: PID field of "dead" child slots no longer displays
6729 main httpd process's PID. [Jim Jagielski]
6731 *) Makefile.nt added - to build all the bits from the command line:
6732 nmake -f Makefile.nt
6733 Doesn't yet work properly. [Ben Laurie]
6735 *) Default text of 404 error is now "Not Found" rather than the
6736 potentially misleading "File Not Found". [Ken Coar]
6738 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
6739 for the net if we require people that actually need this data to
6740 enable it. [Linus Torvalds]
6742 *) directory_walk() is an expensive function, keep a little more state to
6743 avoid needless string counting. Add two new functions make_dirstr_parent
6744 and make_dirstr_prefix which replace all existing uses of make_dirstr.
6745 The new functions are a little less general than make_dirstr, but
6746 work more efficiently (less memory, less string counting).
6749 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
6750 to LDFLAGS) to avoid complications with lex rules in make files.
6751 [Dean Gaudet] PR#372
6753 *) run_method optimized to avoid needless scanning over NULLs in the
6754 module list. [Dean Gaudet]
6756 *) Revamp of (unix) scoreboard management code such that it avoids
6757 unnecessary traversals of the scoreboard on each hit. This is
6758 particularly important for high volume sites with a large
6759 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
6760 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
6761 httpd.h. [Dean Gaudet]
6763 *) In configurations using multiple Listen statements it was possible for
6764 busy sockets to starve other sockets of service. [Dean Gaudet]
6766 *) Added hook so standalone_main can be replaced at compile time
6767 (define STANDALONE_MAIN)
6770 *) Lowest-level read/write functions in buff.c will be replaced with
6771 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
6772 compile time. The default sfio discipline will behave as apache
6773 would without sfio compiled in.
6776 *) Enhance UserDir directive (mod_userdir) to accept a list of
6777 usernames for the 'disable' keyword, and add 'enable user...' to
6778 selectively *en*able userdirs if they're globally disabled.
6781 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
6782 will work with Netscape dbm files. (dbmmanage will probably not
6783 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
6785 *) Add a ListenBacklog directive to control the backlog parameter
6786 passed to listen(). Also change the default to 511 from 512.
6789 *) API: A new handler response DONE which informs apache that the
6790 request has been handled and it can finish off quickly, similar to
6791 how it handles errors. [Rob Hartill]
6793 *) Turn off chunked encoding after sending terminating chunk/footer
6794 so that we can't do it twice by accident. [Roy Fielding]
6796 *) mod_expire also issues Cache-Control: max-age headers.
6799 *) API: Added kill_only_once option for free_proc_chain so that it won't
6800 aggressively try to kill off specific children. For fastcgi.
6801 [Stanley Gambarin <gambarin@OpenMarket.com>]
6803 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
6805 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
6806 When used together, these cause mod_dir to emit HEIGHT and WIDTH
6807 attributes in the FancyIndexing IMG tags. [Ken Coar]
6809 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
6811 *) PORT: Added Windows NT support
6812 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
6814 Changes with Apache 1.2.6
6816 *) mod_include when using XBitHack Full would send ETags in addition to
6817 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
6818 [Dean Gaudet] PR#1133
6820 *) SECURITY: When a client connects to a particular port/addr, and
6821 gives a Host: header ensure that the virtual host requested can
6822 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
6824 *) Support virtual hosts with wildcard port and/or multiple ports
6825 properly. [Ed Korthof <ed@organic.com>]
6827 *) Fixed some case-sensitivity issues according to RFC2068.
6830 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
6831 and mod_include.c. [Dean Gaudet]
6833 *) Variable 'cwd' was being used pointlessly before being set.
6836 *) SIGURG doesn't exist on all platforms.
6837 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
6839 *) When an error occurs during a POST, or other operation with a
6840 request body, the body has to be read from the net before allowing
6841 a keepalive session to continue. [Roy Fielding] PR#1399
6843 *) When an error occurs in fcntl() locking suggest the user look up
6844 the docs for LockFile. [Dean Gaudet]
6846 *) table_set() and table_unset() did not deal correctly with
6847 multiple occurrences of the same key. [Stephen Scheck
6848 <sscheck@infonex.net>, Ben Laurie] PR#1604
6850 *) send_fd_length() did not calculate total_bytes_sent properly in error
6851 cases. [Ben Reser <breser@regnow.com>] PR#1366
6853 *) r->connection->user was allocated in the wrong pool causing corruption
6854 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
6856 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
6857 Also removed the auto-generated link to www.apache.org that was the
6858 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
6860 *) Multiple "close" tokens may have been set in the "Connection"
6861 header, not an error, but a waste.
6862 [Ronald.Tschalaer@psi.ch] PR#1683
6864 *) "basic" and "digest" auth tokens should be tested case-insensitive.
6865 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
6867 *) It appears the "257th byte" bug (see
6868 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
6869 at the 256th byte as well. Fixed. [Dean Gaudet]
6871 *) mod_rewrite would not handle %3f properly in some situations.
6874 *) Apache could generate improperly chunked HTTP/1.1 responses when
6875 the bputc() or rputc() functions were used by modules (such as
6876 mod_include). [Dean Gaudet]

6879 some ports. [Ralf Engelschall]

6885 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
6887 Changes with Apache 1.2.5
6889 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
6890 only an issue on systems without a MAXDNAME define or where
6891 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
6893 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
6896 *) Fix core dump in the ftp proxy when reading incorrectly formatted
6897 directory listings. [Marc Slemko]
6899 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
6902 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
6903 is used to read various types of files such as htaccess and
6904 htpasswd files. [Marc Slemko]
6906 *) SECURITY: Ensure that the buffer returned by ht_time is always
6907 properly null terminated. [Marc Slemko]
6909 *) SECURITY: General mod_include cleanup, including fixing several
6910 possible buffer overflows and a possible infinite loop. This cleanup
6911 was done against 1.3 code and then backported to 1.2, the result
6912 is a large difference (due to indentation cleanup in 1.3 code).
6913 Users interested in seeing a smaller set of relevant differences
6914 should consider comparing against src/modules/standard/mod_include.c
6915 from the 1.3b3 release. Non-indentation changes to mod_include
6916 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
6918 *) SECURITY: Numerous changes to mod_imap in a general cleanup
6919 including fixing a possible buffer overflow. This cleanup also
6920 was done with 1.3 code as a basis, see the the previous note
6921 about mod_include. [Dean Gaudet]
6923 *) SECURITY: If a htaccess file can not be read due to bad
6924 permissions, deny access to the directory with a HTTP_FORBIDDEN.
6925 The previous behavior was to ignore the htaccess file if it could not
6926 be read. This change may make some setups with unreadable
6927 htaccess files stop working. PR#817 [Marc Slemko]
6929 *) SECURITY: no2slash() was O(n^2) in the length of the input.
6930 Make it O(n). This inefficiency could be used to mount a denial
6931 of service attack against the Apache server. Thanks to

6944 r->filename. Since those two are meant to be in sync with each other
6945 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]

6957 Changes with Apache 1.2.4
6959 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
6960 always making requests with the full-URI instead of just the URI path.
6961 [Marc Slemko, Roy Fielding]
6963 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
6964 on this platform. [Marc Slemko]
6966 Changes with Apache 1.2.3
6968 *) The request to a remote proxy was mangled if it was generated as the
6969 result of a ProxyPass directive. URL schemes other than http:// were not
6970 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
6971 PR#812 [Lars Eilebrecht]
6973 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
6974 information for case where proxy module is not available. [Marc Slemko]
6976 *) Force proxy to always respond as HTTP/1.0, which it was failing to
6977 do for errors and cached responses. [Roy Fielding]
6979 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
6981 Changes with Apache 1.2.2 [not released]
6983 *) Fixed another long-standing bug in sub_req_lookup_file where it would
6984 happily skip past access checks on subdirectories looked up with relative
6985 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
6988 *) Add lockfile name to error message printed out when
6989 USE_FLOCK_SERIALIZED_ACCEPT is defined.
6992 *) Enhanced the chunking and error handling inside the buffer functions.
6993 [Dean Gaudet, Roy Fielding]
6995 *) When merging the main server's <Directory> and <Location> sections into
6996 a vhost, put the main server's first and the vhost's second. Otherwise
6997 the vhost can't override the main server. [Dean Gaudet] PR#717
6999 *) The <Directory> code would merge and re-merge the same section after
7000 a match was found, possibly causing problems with some modules.
7003 *) Fixed an infinite loop in mod_imap for references above the server root.
7004 [Dean Gaudet] PR#748
7006 *) mod_include cleanup showed that handle_else was being used to handle
7007 endif. It didn't cause problems, but it was cleaned up too.
7010 *) Last official synchronization of mod_rewrite with author version (because
7011 mod_rewrite is now directly developed by the author at the Apache Group):
7012 o added diff between mod_rewrite 3.0.6+ and 3.0.9
7013 minus WIN32/NT stuff, but plus copyright removement.
7015 - workaround for detecting infinite rewriting loops
7016 - fixed setting of env vars when "-" is used as subst string
7017 - fixed forced response code on redirects (PR#777)
7018 - fixed cases where r->args is ""
7019 - kludge to disable locking on pipes under braindead SunOS
7020 - fix for rewritelog in cases where remote hostname is unknown
7021 - fixed totally damaged request_rec walk-back loop
7022 o remove static from local data and add static to global ones.
7023 o replaced ugly proxy finding stuff by simple
7024 find_linked_module("mod_proxy") call.
7025 o added missing negation char on rewritelog()
7026 o fixed a few comment typos
7027 [Ralf S. Engelschall]
7029 *) Anonymous_LogEmail was logging on each subrequest.
7030 [Dean Gaudet] PR#421, PR#868
7032 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7033 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7034 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
7035 Additionally mod_browser now triggers during translate_name to workaround
7036 a deficiency in the header_parse phase.

7046 *) The proxy didn't treat the "Host:" keyword of the host header as case-
7047 insensitive. The proxy would corrupt the first line of a response from
7048 an HTTP/0.9 server. [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#813,814
7050 *) mod_include would log some bogus values occasionally.

7053 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
7054 under Solaris 2.x (up through 2.5.1). It has been fixed.
7055 [Dean Gaudet] PR#832
7057 *) API: In HTTP/1.1, whether or not a request message contains a body
7058 is independent of the request method and based solely on the presence
7059 of a Content-Length or Transfer-Encoding. Therefore, our default
7060 handlers need to be prepared to read a body even if they don't know
7061 what to do with it; otherwise, the body would be mistaken for the
7062 next request on a persistent connection. discard_request_body()
7063 has been added to take care of that. [Roy Fielding] PR#378
7065 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
7066 release version number, such that it always increases along the
7067 same lines as our source code branching. [Roy Fielding]
7069 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
7071 Changes with Apache 1.2.1
7073 *) SECURITY: Don't serve file system objects unless they are plain files,
7074 symlinks, or directories. This prevents local users from using pipes
7075 or named sockets to invoke programs for an extremely crude form of

7079 could contain "../" allowing a local user to "publish" any file on
7080 the system. No slashes are allowed now. [Dean Gaudet]
7082 *) SECURITY: It was possible to violate the symlink Options using mod_dir
7083 (headers, readmes, titles), mod_negotiation (type maps), or
7084 mod_cern_meta (meta files). [Dean Gaudet]
7086 *) SECURITY: Apache will refuse to run as "User root" unless
7087 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
7089 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
7090 if it contained a .htaccess disallowing symlinks. This is contrary
7091 to the rule that symlink permissions are tested with the symlink
7092 options of the parent directory. [Dean Gaudet] PR#353
7094 *) CONFIG: The LockFile directive can be used to place the serializing
7095 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
7096 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
7099 *) Request processing now retains state of whether or not the request
7100 body has been read, so that internal redirects and subrequests will
7101 not try to read it twice (and block). [Roy Fielding]
7103 *) Add a placeholder in modules/Makefile to avoid errors with certain
7104 makes. [Marc Slemko]
7106 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.

7112 *) Attempt to work around problems with third party libraries that do not
7113 handle high numbered descriptors (examples include bind, and
7114 solaris libc). On all systems apache attempts to keep all permanent
7115 descriptors above 15 (called the low slack line). Solaris users
7116 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
7117 which keeps all non-FILE * descriptors above 255. On all systems
7118 this should make supporting large numbers of vhosts with many open
7119 log files more feasible. If this causes trouble please report it,
7120 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
7121 [Dean Gaudet] various PRs
7123 *) Related to the last entry, network sockets are now opened before
7124 log files are opened. The only known case where this can cause
7125 problems is under Solaris with many virtualhosts and many Listen
7126 directives. But using -DHIGH_SLACK_LINE=256 described above will
7127 work around this problem. [Dean Gaudet]

7182 reading from one buffer and writing to another, at least until it has
7183 a custom timeout handler. [Roy Fielding and Petr Lampa]

7218 *) If a soft_timeout occurs after keepalive is set, then the main child
7219 loop would try to read another request even though the connection
7220 has been aborted. [Roy Fielding]
7222 *) Configure changes: Allow for whitespace at the start of a
7223 Module declaration. Also, be more understanding about the
7224 CC=/OPTIM= format in Configuration. Finally, fix compiler
7225 flags if using HP-UX's cc compiler. [Jim Jagielski]
7227 *) Subrequests and internal redirects now inherit the_request from the
7228 original request-line. [Roy Fielding]
7230 *) Test for error conditions before creating output header fields, since
7231 we don't want the error message to include those fields. Likewise,
7232 reset the content_language(s) and content_encoding of the response
7233 before generating or redirecting to an error message, since the new
7234 message will have its own Content-* definitions. [Dean Gaudet]

7237 and 304 responses) and err_headers_out (headers sent with all responses).
7238 Avoid the overhead of copying tables if err_headers_out is empty
7239 (the usual case). [Roy Fielding]

7242 not properly checking both the value configured by the DefaultType
7243 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
7244 of DEFAULT_TYPE to match the documented default (text/plain).

7250 *) Properly initialize the flock structures used by the mutex locking
7251 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
7254 *) The method for determining PATH_INFO has been restored to the pre-1.2b
7255 (and NCSA httpd) definition wherein it was the extra path info beyond
7256 the CGI script filename. The environment variable FILEPATH_INFO has
7257 been removed, and instead we supply the original REQUEST_URI to any
7258 script that wants to be Apache-specific and needs the real URI path.
7259 This solves a problem with existing scripts that use extra path info
7260 in the ScriptAlias directive to pass options to the CGI script.
7263 *) The _default_ change in 1.2b10 will change the behaviour on configs
7264 that use multiple Listen statements for listening on multiple ports.
7265 But that change is necessary to make _default_ consistent with other
7266 forms of <VirtualHost>. It requires such configs to be modified
7267 to use <VirtualHost _default_:*>. The documentation has been
7268 updated. [Dean Gaudet] PR#530
7270 *) If an ErrorDocument CGI script is used to respond to an error
7271 generated by another CGI script which has already read the message
7272 body of the request, the server would block trying to read the
7273 message body again. [Rob Hartill]

7352 parsing of headers. If the terminating empty-line CRLF occurs starting
7353 at the 256th or 257th byte of output, then Navigator will think a normal
7354 image is invalid. We are guessing that this is because their initial
7355 read of a new request uses a 256 byte buffer. We check the bytes written
7356 so far and, if we are about to tickle the bug, we instead insert a
7357 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232

7409 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
7412 Changes with Apache 1.2b8
7414 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
7415 to it. [Marc Slemko]
7417 *) The addition of <Location> and <File> directives made the
7418 sub_req_lookup_simple() function bogus, so we now handle
7419 the special cases directly. [Dean Gaudet]
7421 *) We now try to log where the server is dumping core when a fatal
7422 signal is received. [Ken Coar]
7424 *) Improved lingering_close by adding a special timeout, removing the
7425 spurious log messages, removing the nonblocking settings (they
7426 are not needed with the better timeout), and adding commentary
7427 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
7428 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
7430 *) Send error messages about setsockopt failures to the server error
7431 log instead of stderr. [Roy Fielding]
7433 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
7435 *) Stopgap solution for CGI 3-second delay with server-side includes: if
7436 processing a subrequest, allocate memory from r->main->pool instead
7437 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
7438 in the middle of an SSI request. [Dean Gaudet] PR #122
7440 *) Fixed status of response when POST is received for a nonexistent URL
7441 (was sending 405, now 404) and when any method is sent with a
7442 full-URI that doesn't match the server and the server is not acting
7443 as a proxy (was sending 501, now 403). [Roy Fielding]
7445 *) Host port changed to unsigned short. [Ken Coar] PR #276
7447 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
7449 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
7451 *) Report extra info from errno with many errors that cause httpd to exit.
7452 spawn_child, popenf, and pclosef now have valid errno returns in the
7453 event of an error. Correct problems where errno was stomped on
7454 before being reported. [Dean Gaudet]
7456 *) In the proxy, if the cache filesystem was full, garbage_coll() was
7457 never called, and thus the filesystem would remain full indefinitely.
7458 We now also remove incomplete cache files left if the origin server
7459 didn't send a Content-Length header and either the client has aborted
7460 transfer or bwrite() to client has failed. [Petr Lampa]
7462 *) Fixed the handling of module and script-added header fields.
7463 Improved the interface for sending header fields and reduced
7464 the duplication of code between sending okay responses and errors.
7465 We now always send both headers_out and err_headers_out, and
7466 ensure that the server-reserved fields are not being overridden,
7467 while not overriding those that are not reserved. [Roy Fielding]
7469 *) Moved transparent content negotiation fields to err_headers_out
7470 to reflect above changes. [Petr Lampa]
7472 *) Fixed the determination of whether or not we should make the
7473 connection persistent for all of the cases where some other part
7474 of the server has already indicated that we should not. Also
7475 improved the ordering of the test so that chunked encoding will
7476 be set whenever it is desired instead of only when KeepAlive
7477 is enabled. Added persistent connection capability for most error
7478 responses (those that do not indicate a bad input stream) when
7479 accessed by an HTTP/1.1 client. [Roy Fielding]
7481 *) Added missing timeouts for sending header fields, error responses,
7482 and the last chunk of chunked encoding, each of which could have
7483 resulted in a process being stuck in write forever. Using soft_timeout
7484 requires that the sender check for an aborted connection rather than
7485 continuing after an EINTR. Timeouts that used to be initiated before
7486 send_http_header (and never killed) are now initiated only within or
7487 around the routines that actually do the sending, and not allowed to
7488 propagate above the caller. [Roy Fielding]
7490 *) mod_auth_anon required an @ or a . in the email address, not both.
7493 *) per_dir_defaults weren't set correctly until directory_walk for
7494 name-based vhosts. This fixes an obscure bug with the wrong config
7495 info being used for vhosts that share the same ip as the server.
7498 *) Improved generation of modules/Makefile to be more generic for
7499 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
7501 *) Generate makefile dependency for Configuration based on the actual
7502 name given when running the Configure process. [Dean Gaudet]
7504 *) Fixed problem with vhost error log not being set prior to
7505 initializing virtual hosts. [Dean Gaudet]
7507 *) Fixed infinite loop when a trailing slash is included after a type map
7508 file URL (extra path info). [Petr Lampa]
7510 *) Fixed server status updating of per-connection counters. [Roy Fielding]
7512 *) Add documentation for DNS issues (reliability and security), and try
7513 to explain the virtual host matching process. [Dean Gaudet]
7515 *) Try to continue gracefully by disabling the vhost if a DNS lookup
7516 fails while parsing the configuration file. [Dean Gaudet]
7518 *) Improved calls to setsockopt. [Roy Fielding]
7520 *) Negotiation changes: Don't output empty content-type in variant list;
7521 Output charset in variant list; Return sooner from handle_multi() if
7522 no variants found; Add handling of '*' wildcard in Accept-Charset.
7523 [Petr Lampa and Paul Sutton]
7525 *) Fixed overlaying of request/sub-request notes and headers in
7526 mod_negotiation. [Dean Gaudet]
7528 *) If two variants' charset quality are equal and one is the default
7529 charset (iso-8859-1), then prefer the variant that was specifically
7530 listed in Accept-Charset instead of the default. [Petr Lampa]
7532 *) Memory allocation problem in push_array() -- it would corrupt memory
7533 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
7535 *) invoke_handler() doesn't handle mime arguments in content-type
7538 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
7541 *) Fixed problem with ErrorDocument not working for virtual hosts
7542 due to one of the performance changes in 1.2b7. [Dean Gaudet]
7544 *) Log an error message if we get a request header that is too long,
7545 since it may indicate a buffer overflow attack. [Marc Slemko]
7547 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
7548 not reject URLs without a double-slash, as per RFC2068 section 3.2.
7549 [Ken Coar] PR #146, #187
7551 *) Added table entry placeholder for new header_parser callback
7552 in all of the distributed modules. [Ken Coar] PR #191
7554 *) Allow for cgi files without the .EXE extension on them under OS/2.
7555 [Garey Smiley] PR #59
7557 *) Fixed error message when resource is not found and URL contains
7558 path info. [Petr Lampa and Dean Gaudet] PR #40
7560 *) Fixed user and server confusion over what should be a virtual host
7561 and what is the main server, resulting in access to something
7562 other than the name defined in the virtualhost directive (but
7563 with the same IP address) failing. [Dean Gaudet]
7565 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
7566 AIX; improves the redirection stuff to enable the users to generally
7567 redirect to http, https, gopher and ftp; added TIME variable for
7568 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
7569 special patterns >STRING, <STRING and =STRING to RewriteCond, which
7570 can be used in conjunction with %{TIME} or other variables to create
7571 time-dependent rewriting rules. [Ralf S. Engelschall]
7573 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
7574 Module authors may need to adjust their code for proper cleanup to take
7575 place (that is, call note_cleanups_for_fd()). This change fixes problems
7576 with file descriptors being erroneously closed when the proxy module was
7577 in use. [Ben Laurie]
7579 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
7580 initgroups() to hose the group information needed for later
7581 comparisons. [Randy Terbush]
7583 *) Remove unnecessary call to va_end() in create_argv() which
7584 caused a SEGV on some systems.
7586 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
7589 *) Clear memory allocated for listeners. [Randy Terbush]
7591 *) Improved handling of IP address as a virtualhost address and
7592 introduced "_default_" as a synonym for the default vhost config.
7593 [Dean Gaudet] PR #212
7595 Changes with Apache 1.2b7
7597 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
7599 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
7601 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
7602 - replace protocol response numbers with symbols
7603 - save variant-list into main request notes
7604 - free allocated memory from subrequests
7605 - merge notes, headers_out and err_headers_out
7607 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
7608 "HTTP/#.# ###*" to be more lenient about what we accept.
7611 *) more proxy FTP bug fixes:
7612 - Changed send_dir() to remove user/passwd from displayed URL.
7613 - Changed login error messages to be more descriptive.
7614 - remove setting of SO_DEBUG socket option
7615 - Make ftp_getrc() more lenient about multiline responses,
7616 specifically, 230 responses which don't have continuation 230-
7617 on each line). These seem to be all NT FTP servers, and while
7618 perhaps questionable, they appear to be legal by RFC 959.
7619 - Add missing kill_timeout() after transfer to user completes.
7622 *) Fixed problem where a busy server could hang when restarting
7623 after being sent a SIGHUP due to child processes not exiting.
7626 *) Modify mod_include escaping so a '\' only signifies an escaped
7627 character if the next character is one that needs
7628 escaping. [Ben Laurie]
7630 *) Eliminated possible infinite loop in mod_imap when relative URLs are
7631 used with a 'base' directive that does not have a '/' in it.
7632 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
7634 *) Reduced the default timeout from 1200 seconds to 300, and the
7635 one in the sample configfile from 400 to 300. [Marc Slemko]
7637 *) Stop vbprintf from crashing if given a NULL string pointer;
7638 print (null) instead. [Ken Coar]
7640 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
7641 [Marc Slemko and Roy Fielding]
7643 *) Fixed problem with mod_cgi-generated internal redirects trying to
7644 read the request message-body twice. [Archie Cobbs and Roy Fielding]
7646 *) Reduced timeout on lingering close, removed possibility of a blocked
7647 read causing the child to hang, and stopped logging of errors if
7648 the socket is not connected (reset by client). [Roy Fielding]
7650 *) Rearranged main child loop to remove duplication of code in
7651 select/accept and keep-alive requests, fixed several bugs regarding
7652 checking scoreboard_image for exit indication and failure to
7653 account for all success conditions and trap all error conditions,
7654 prevented multiple flushes before closing the socket; close the entire
7655 socket buffer instead of just one descriptor, prevent logging of
7656 EPROTO and ECONNABORTED on platforms where supported, and generally
7657 improved readability. [Roy Fielding]
7659 *) Extensive performance improvements. Cleaned up inefficient use of
7660 auto initializers, multiple is_matchexp calls on a static string,
7661 and excessive merging of response_code_strings. [Dean Gaudet]
7663 *) Added double-buffering to mod_include to improve performance on
7664 server-side includes. [Marc Slemko]
7666 *) Several fixes for suexec wrapper. [Randy Terbush]
7667 - Make wrapper work for files on NFS filesystem.
7668 - Fix portability problem of MAXPATHLEN.
7669 - Fix array overrun problem in clean_env().
7670 - Fix allocation of PATH environment variable
7672 *) Removed extraneous blank line is description of mod_status chars.
7675 *) Logging of errors from the call_exec routine simply went nowhere,
7676 since the logfile fd has been closed, so now we send them to stderr.
7677 [Harald T. Alvestrand]
7679 *) Fixed core dump when DocumentRoot is a CGI.
7680 [Ben Laurie, reported by geddis@tesserae.com]
7682 *) Fixed potential file descriptor leak in mod_asis; updated it and
7683 http_core to use pfopen/pfclose instead of fopen/fclose.
7684 [Randy Terbush and Roy Fielding]
7686 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
7687 as the DEC Alpha which is 64-bit but uses 32-bit ints.
7688 [Dean Gaudet and Ken Coar]
7690 *) Return a 302 response code to the client when sending a redirect
7691 due to a missing trailing '/' on a directory instead of a 301; now
7692 it is cacheable. [Markus Gyger]
7694 *) Fix condition where, if a bad directive occurs in .htaccess, and
7695 sub_request() goes first to this directory, then log_reason() will
7696 SIGSEGV because it doesn't have initialized r->per_dir_config.
7697 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
7699 *) Fix handling of lang_index in is_variant_better(). This was
7700 causing problems which resulted in the server sending the
7701 wrong language document in some cases. [Petr Lampa]
7703 *) Remove free() from clean_env() in suexec wrapper. This was nuking
7704 the clean environment on some systems.
7706 *) Tweak byteserving code (e.g. serving PDF files) to work around
7707 bugs in Netscape Navigator and Microsoft Internet Explorer.
7708 Emit Content-Length header when sending multipart/byteranges.
7711 *) Port to HI-UX/WE2. [Nick Maclaren]
7713 *) Port to HP MPE operating system for HP 3000 machines
7714 [Mark Bixby <markb@cccd.edu>]
7716 *) Fixed bug which caused a segmentation fault if only one argument
7717 given to RLimit* directives. [Ed Korthof]
7719 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
7721 *) Improved buffered output to the client by delaying the flush decision
7722 until the BUFF code is actually about to read the next request.
7723 This fixes a problem introduced in 1.2b5 with clients that send
7724 an extra CRLF after a POST request. Also improved chunked output
7725 performance by combining writes using writev() and removing as
7726 many bflush() calls as possible. NOTE: Platforms without writev()
7727 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
7728 or Configure, unless we have already done so. [Dean Gaudet]
7730 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
7732 *) Fixed mod_info output corruption bug introduced by buffer overflow
7733 fixes. [Dean Gaudet]
7735 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
7736 for the special case of a 304 response. [Paul Sutton]
7738 *) Improved handling of TRACE method by bypassing normal method handling
7739 and header parsing routines; fixed Allow response to always allow TRACE.
7742 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
7744 *) Cleaned-up some of the generated HTML. [Ken Coar]
7746 Changes with Apache 1.2b6
7748 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
7750 *) Fix typo introduced in fix for potential infinite loop around
7751 accept() in child_main(). This change caused the rev to 1.2b6.
7752 1.2b5 was never a public beta.
7754 Changes with Apache 1.2b5
7756 *) Change KeepAlive semantics (On|Off instead of a number), add
7757 MaxKeepAliveRequests directive. [Alexei Kosut]
7759 *) Various NeXT compilation patches, as well as a change in
7760 regex/regcomp.c since that file also used a NEXT define.
7763 *) Allow * to terminate the end of a directory match in mod_dir.
7764 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
7766 *) Don't call can_exec() if suexec_enabled. Calling this requires
7767 scripts executed by the suexec wrapper to be world executable, which
7768 defeats one of the advantages of running the wrapper. [Randy Terbush]
7770 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
7773 *) Migration from sprintf() to snprintf() to avoid buffer
7774 overflows. [Marc Slemko]
7776 *) Provide portable snprintf() implementation (ap_snprintf)
7777 as well as *cvt family. [Jim Jagielski]
7779 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
7782 *) Remove mod_fastcgi.c from the distribution. This module appears
7783 to be maintained more through the Open Market channels and should
7784 continue to be easily available at http://www.fastcgi.com/
7786 *) Fixed bug in modules/Makefile that wouldn't allow building in more
7787 than one subdirectory (or cleaning, either). [Jeremy Laidman]
7789 *) mod_info assumed that the config files were relative to ServerRoot.
7792 *) CGI scripts called as an error document resulting from failed
7793 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
7795 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
7798 *) Properly check errno to prevent display of a directory index
7799 when server receives a long enough URL to confuse stat().
7802 *) Several security enhancements to suexec wrapper. It is _highly_
7803 recommended that previously installed versions of the wrapper
7804 be replaced with this version. [Randy Terbush, Jason Dour]
7806 - ~user execution now properly restricted to ~user's home
7807 directory and below.
7808 - execution restricted to UID/GID > 100
7809 - restrict passed environment to known variables
7810 - call setgid() before initgroups() (portability fix)
7811 - remove use of setenv() (portability fix)
7813 *) Add HTTP/1.0 response forcing. [Ben Laurie]
7815 *) Add access control via environment variables. [Ben Laurie]
7817 *) Add rflush() function. [Alexei Kosut]
7819 *) remove duplicate pcalloc() call in new_connection().
7821 *) Fix incorrect comparison which could allow number of children =
7822 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
7823 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
7825 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
7826 AIX PS/2, CONVEXOS. [Jim Jagielski]
7828 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
7829 It's more portable. [Martin Kraemer]
7831 *) Replace references to make in Makefile.tmpl with $(MAKE).
7834 *) Add ProxyBlock directive w/IP address caching. Add IP address
7835 caching to NoCache directive as well. ProxyBlock works with all
7836 handlers; NoCache now also works with FTP for anonymous logins.
7837 Still more code cleanup. [Chuck Murcko]
7839 *) Add "header parse" API hook [Ben Laurie]
7841 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
7843 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
7845 *) Correctly allow access and auth directives in <Files> sections in
7846 server config files. [Alexei Kosut]
7848 *) Fix bug with ServerPath that could cause certain files to be not
7849 found by the server. [Alexei Kosut]
7851 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
7852 double-quote from text and so that it properly checks for unsupported
7853 status codes using the new index_of_response interface. [Roy Fielding]
7855 *) Multiple fixes to the lingering_close code in order to avoid being
7856 interrupted by a stray timeout, to avoid lingering on a connection
7857 that has already been aborted or never really existed, to ensure that
7858 we stop lingering as soon as any error condition is received, and to
7859 prevent being stuck indefinitely if the read blocks. Also improves
7860 reporting of error conditions. [Marc Slemko and Roy Fielding]
7862 *) Fixed initialization of parameter structure for sigaction.
7863 [mgyger@itr.ch, Adrian Filipi-Martin]
7865 *) Fixed reinitializing the parameters before each call to accept and
7866 select, and removed potential for infinite loop in accept.
7867 [Roy Fielding, after useful PR from adrian@virginia.edu]
7869 *) Fixed condition where, if a child fails to fork, the scoreboard would
7870 continue to say SERVER_STARTING forever. Eventually, the main process
7871 would refuse to start new children because count_idle_servers() will
7872 count those SERVER_STARTING entries and will always report that there
7873 are enough idle servers. [Phillip Vandry]
7875 *) Fixed bug in bcwrite regarding failure to account for partial writes.
7876 Avoided calling bflush() when the client is pipelining requests.
7877 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
7879 *) Added description of "." mode in server-status [Jim Jagielski]
7881 Changes with Apache 1.2b4
7883 *) Fix possible race condition in accept_mutex_init() that
7884 could leave a small security hole open allowing files to be
7885 overwritten in cases where the server UID has write permissions.
7888 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
7890 *) Fix portablity problem in util_script where ARG_MAX may not be
7891 defined for some systems.
7893 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
7896 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
7897 style magic #! token for better script portability. [Garey Smiley]
7899 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
7900 execution for ~userdir CGI. [Jason Dour]
7902 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
7904 *) Fix month off by one in suexec wrapper logging.
7906 Changes with Apache 1.2b3:
7908 *) Fix error in mod_cgi which could cause resources not to be properly
7909 freed, or worse. [Dean Gaudet]
7911 *) Fix find_string() NULL pointer dereference. [Howard Fear]
7913 *) Add set_flag_slot() at the request of Dirk and others.
7916 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
7918 *) Add changes to improve the error message given for invalid
7919 ServerName parameters. [Dirk vanGulik]
7921 *) Add "Authoritative" directive for Auth modules that don't
7922 currently have it. This gives admin control to assign authoritative
7923 control to an authentication scheme and allow "fall through" for
7924 those authentication modules that aren't "Authoritative" thereby
7925 allowing multiple authentication mechanisms to be chained.
7928 *) Remove requirement for ResourceConfig/AccessConfig if not using
7929 the three config file layout. [Randy Terbush]
7931 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
7933 *) Changes to suexec wrapper to fix the following problems:
7934 1. symlinked homedirs will kill ~userdirs.
7935 2. initgroups() on Linux 2.0.x clobbers gr->grid.
7936 3. CGI command lines paramters problems
7937 4. pw-pwdir for "docroot check" still the httpd user's pw record.
7938 [Randy Terbush, Jason Dour]
7940 *) Change create_argv() to accept variable arguments. This fixes
7941 a problem where arguments were not getting passed to the CGI via
7942 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
7944 *) Collapse multiple slashes in path URLs to properly apply
7945 handlers defined by <Location>. [Alexei Kosut]
7947 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
7949 *) Improve the accuracy of request duration timings by setting
7950 r->request_time in read_request_line() instead of read_request().
7953 *) Reset timeout while reading via get_client_block() in mod_cgi.c
7954 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
7956 *) Add the ability to pass different Makefile.tmpl files to Configure
7957 using the -make flag. [Rob Hartill]
7959 *) Fix coredump triggered when sending a SIGHUP to the server caused
7960 by an assertion failure, in turn caused by an uninitialised field in a
7964 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
7965 PATH_INFO from previous versions of Apache (in certain situations,
7966 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
7967 [later removed in 1.2b11]
7969 *) Add rwrite() function to API to allow for sending strings of
7970 arbitrary length. [Doug MacEachern]
7972 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
7974 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
7975 NeXT. [Jim Jagielski]
7977 *) Removed recent modification to promote the status code on internal
7978 redirects, since the correct fix was to change the default log format
7979 in mod_log_config so that it outputs the original status. [Rob Hartill]
7981 Changes with Apache 1.2b2:
7983 *) Update set_signals() to use sigaction() for setting handlers.
7984 This appears to fix a re-entrant problem in the seg_fault()
7985 bus_error() handlers. [Randy Terbush]
7987 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
7989 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
7991 *) proxy_http.c bugfixes: [Chuck Murcko]
7992 1) fixes possible NULL pointer reference w/NoCache
7993 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
7994 host would cache nothing if it was in the local domain,
7995 and the local domain was in the NoCache list)
7996 3) Adds Host: header when not available
7997 4) Some code cleanup and clarification
7999 *) mod_include.c bugfixes:
8000 1) Fixed an ommission that caused include variables to not
8001 be parsed in config errmsg directives [Howard Fear]
8002 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
8003 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
8004 4) Allow backslash-escaping to all quoted text
8005 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
8006 5) Pass variable to command line if not set in XSSI's env
8009 *) Fix infinite loop when processing Content-language lines in
8010 type-map files. [Alexei Kosut]
8012 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
8014 *) Fixed problem in set_[user|group] that prevented CGI execution
8015 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
8017 *) Added PORTING information file. [Jim Jagielski]
8019 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
8021 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
8023 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
8024 USE_FCNTL_SERIALIZED_ACCEPT was intended.
8026 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
8027 which caused problems of systems where socket s_addr is >32bits.
8029 *) Added comment to explain (r->chunked = 1) side-effect in
8030 http_protocol.c [Roy Fielding]
8032 *) Replaced use of index() in mod_expires.c with more appropriate
8033 and portable isdigit() test. [Ben Laurie]
8035 *) Updated Configure for ...
8036 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
8037 *-dg-dgux* (bad pattern match)
8038 QNX (DEF_WANTHSREGEX=yes)
8039 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
8042 and added some user diagnostic info. [Ben Laurie]
8044 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
8045 for better portability. [Jim Jagielski]
8047 *) Updated helpers/GuessOS for ...
8048 SCO 5 (recognize minor releases)
8049 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
8050 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
8051 IRIX64 (-sgi-irix64)
8052 ULTRIX (-unknown-ultrix)
8053 SINIX (-whatever-sysv4)
8054 NCR Unix (-ncr-sysv4)
8055 and fixed something in helpers/PrintPath [Ben Laurie]
8057 Changes with Apache 1.2b1
8059 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
8061 Changes with Apache 1.1.1
8063 *) Fixed bug where Cookie module would make two entries in the
8064 logfile for each access [Mark Cox]
8066 *) Fixed bug where Redirect in .htaccess files would cause memory
8067 leak. [Nathan Neulinger]
8069 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
8071 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
8073 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
8075 Changes with Apache 1.1.0
8077 *) Bring NeXT support up to date. [Takaaki Matsumoto]
8079 *) Bring QNX support up to date. [Ben Laurie]
8081 *) Make virtual hosts default to main server keepalive parameters.
8082 [Alexei Kosut, Ben Laurie]
8084 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
8086 *) Fix missing address family for connect, also remove unreachable statement
8087 in mod_proxy. [Ben Laurie]
8089 *) mod_env now turned on by default in Configuration.tmpl.
8091 *) Bugs which were fixed:
8092 a) yet more mod_proxy bugs [Ben Laurie]
8093 b) CGI works again with inetd [Alexei Kosut]
8094 c) Leading colons were stripped from passwords [osm@interguide.com]
8095 d) Another fix to multi-method Limit problem [jk@tools.de]
8097 Changes with Apache 1.1b4
8099 *) r->bytes_sent variable restored. [Robert Thau]
8101 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
8103 *) More possibly unsecure programs removed from the support directory.
8105 *) More mod_auth_msql authentication improvements.
8107 *) VirtualHosts based on Host: headers no longer conflict with the
8110 *) OS/2 compatibility enhancements. [Gary Smiley]
8112 *) POST now allowed to directory index CGI scripts.
8114 *) Actions now work with files of the default type.
8116 *) Bugs which were fixed:
8117 a) more mod_proxy bugs
8118 b) early termination of inetd requests
8119 c) compile warnings on several systems
8120 d) problems when scripts stop reading output early
8122 Changes with Apache 1.1b3
8124 *) Much of cgi-bin and all of cgi-src has been removed, due to
8125 various security holes found and that we could no longer support
8128 *) The "Set-Cookie" header is now special-cased to not merge multiple
8129 instances, since certain popular browsers can not handle multiple
8130 Set-Cookie instructions in a single header. [Paul Sutton]
8132 *) rprintf() added to buffer code, occurrences of sprintf removed.
8135 *) CONNECT method for proxy module, which means tunneling SSL should work.
8136 (No crypto needed) Also a NoCache config directive.
8138 *) Several API additions: pstrndup(), table_unset() and get_token()
8139 functions now available to modules.
8141 *) mod_imap fixups, in particular Location: headers are now complete
8144 *) New "info" module which reports on installed module set through a
8145 special URL, a la mod_status.
8147 *) "ServerPath" directive added - allows for graceful transition
8148 for Host:-header-based virtual hosts.
8150 *) Anonymous authentication module improvements.
8152 *) MSQL authentication module improvements.
8154 *) Status module design improved - output now table-based. [Ben Laurie]
8156 *) htdigest utility included for use with digest authentication
8159 *) mod_negotiation: Accept values with wildcards to be treated with
8160 less priority than those without wildcards at the same quality
8161 value. [Alexei Kosut]
8163 *) Bugs which were fixed:
8164 a) numerous mod_proxy bugs
8165 b) CGI early-termination bug [Ben Laurie]
8166 c) Keepalives not working with virtual hosts
8167 d) RefererIgnore problems
8168 e) closing fd's twice in mod_include (causing core dumps on
8169 Linux and elsewhere).
8171 Changes with Apache 1.1b2
8174 a) core dumps in mod_digest
8175 b) truncated hostnames/ip address in the logs
8176 c) relative URL's in mod_imap map files
8178 Changes with Apache 1.1b1
8180 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
8182 Changes with Apache 1.0.3
8184 *) Internal redirects which occur in mod_dir.c now preserve the
8185 query portion of a request (the bit after the question mark).
8188 *) Escape active characters '<', '>' and '&' in html output in
8189 directory listings, error messages and redirection links.
8192 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
8194 *) Fix for POSIX compliance in waiting for processes in alloc.c.
8197 *) setsockopt no longer takes a const declared argument [Martijn Koster]
8199 *) Reset timeout timer after each successful fwrite() to the network.
8200 This patch adds a reset_timeout() procedure that is called by
8201 send_fd() to reset the timeout ever time data is written to the net.
8204 *) timeout() signal handler now checks for SIGPIPE and reports
8205 lost connections in a more user friendly way. [Rob Hartill]
8207 *) Location of the "scoreboard" file which used to live in /tmp is
8208 now configurable (for OSes that can't use mmap) via ScoreBoardFile
8209 which works similar to PidFile (in httpd.conf) [Rob Hartill]
8211 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
8213 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
8214 which caused a SEGV with cookies enabled
8216 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
8219 *) Log the UNIX textual error returned by some system calls, in
8220 particular errors from accept() [David Robinson]
8222 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
8224 Changes with Apache 1.0.2
8226 *) patch to get Apache compiled on UnixWare 2.x, recommended as
8227 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
8229 *) Fix get_basic_auth_pw() to set the auth_type of the request.
8232 *) past changes to http_config.c to only use the
8233 setrlimit function on systems defining RLIMIT_NOFILE
8234 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
8235 for SUNOS and prototypes the needed functions.
8237 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
8240 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
8242 *) Merge multiple headers from CGI scripts instead of taking last
8243 one. [David Robinson]
8245 *) Add support for SCO 5. [Ben Laurie]
8247 Changes with Apache 1.0.1
8249 *) Silence mod_log_referer and mod_log_agent if not configured
8252 *) Recursive includes can occur if the client supplies PATH_INFO data
8253 and the server provider uses relative links; as file.html
8254 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
8256 *) The replacement for initgroups() did not call {set,end}grent(). This
8257 had two implications: if anything else used getgrent(), then
8258 initgroups() would fail, and it was consuming a file descriptor.
8261 *) On heavily loaded servers it was possible for the scoreboard to get
8262 out of sync with reality, as a result of a race condition.
8263 The observed symptoms are far more Apaches running than should
8264 be, and heavy system loads, generally followed by catastrophic
8265 system failure. [Ben Laurie]
8267 *) Fix typo in license. [David Robinson]
8269 Changes with Apache 1.0.0 23 Nov 1995
8271 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
8273 Changes with Apache 0.8.16 05 Nov 1995
8275 *) New man page for 'httpd' added to support directory [David Robinson]
8277 *) .htgroup files can have more than one line giving members for a
8278 given group (each must have the group name in front), for NCSA
8279 back-compatibility [Robert Thau]
8281 *) Mutual exclusion around accept() is on by default for SVR4 systems
8282 generally, since they generally can't handle multiple processes in
8283 accept() on the same socket. This should cure flaky behavior on
8284 a lot of those systems. [David Robinson]
8286 *) AddType, AddEncoding, and AddLanguage directives take multiple
8287 extensions on a single command line [David Robinson]
8289 *) UserDir can be disabled for a given virtual host by saying
8290 "UserDir disabled" in the <VirtualHost> section --- it was a bug
8291 that this didn't work. [David Robinson]
8293 *) Compiles on QNX [Ben Laurie]
8295 *) Corrected parsing of ctime time format [David Robinson]
8297 *) httpd does a perror() before exiting if it can't log its pid
8298 to the PidFile, to make diagnosing the error a bit easier.
8301 *) <!--#include file="..."--> can no longer include files in the
8302 parent directory, for NCSA back-compatibility. [David Robinson]
8304 *) '~' is *not* escaped in URIs generated for directory listings
8307 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
8309 *) Fixed bug involving handling URIs with escaped %-characters
8310 in redirects [David Robinson]
8312 Changes with Apache 0.8.15 14 Oct 1995
8314 *) Switched to new, simpler license
8316 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
8318 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
8320 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
8322 *) Correctly handles internal redirects to files with names containing '%'
8325 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
8327 *) Use geteuid() rather than getuid() to see if we have root privilege,
8328 so that server correctly resets privilege if run setuid root. [Andrew
8331 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
8334 *) Fix relative URLs in imagemap files [Randy Terbush]
8336 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
8339 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
8340 entries all name the same one. [David Robinson]
8342 *) Fix directory listings with filenames containing unusual characters
8345 *) Better URI-escaping for generated URIs in directories with filenames
8346 containing unusual characters [Ben Laurie]
8348 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
8350 *) Unblock alarms on error return from spawn_child() [David Robinson]
8352 *) Sample Config files have extra note for SCO users [Ben Laurie]
8354 *) Configuration has note for HP-UX users [Rob Hartill]
8356 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
8358 *) Nuked bogus #define in httpd.h [David Robinson]
8360 *) Better test for whether a system has setrlimit() [David Robinson]
8362 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
8364 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
8367 Changes with Apache 0.8.14 19 Sep 1995
8369 *) Compiles on SCO ODT 3.0 [Ben Laurie]
8371 *) AddDescription works (better) [Ben Laurie]
8373 *) Leaves an intelligible error diagnostic when it can't set group
8374 privileges on standalone startup [Andrew Wilson]
8376 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
8377 that machine, which claims to be BSD but does not support RLIMIT.
8380 *) gcc -Wall no longer complains about an unused variable when util.c
8381 is compiled with -DMINIMAL_DNS [Andrew Wilson]
8383 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
8385 Changes with Apache 0.8.13 07 Sep 1995
8387 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
8389 *) Have built-in imagemap code recognize & honor Point directive [James
8392 *) Generate cleaner directory listings in directories with a mix of
8393 long and short filenames [Rob Hartill]
8395 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
8397 *) Properly default ServerName for virtual servers [Robert Thau]
8399 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
8400 Paul Richards and a cast of thousands...]
8402 *) On self-identified BSD systems (we don't try to guess any more),
8403 allocate a few extra file descriptors per virtual host with setrlimit,
8404 if we can, to avoid running out. [Randy Terbush]
8406 *) Write 22-character lock file name into buffer with enough space
8407 on startup [Konstantin Olchanski]
8409 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
8412 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
8414 *) Suppress -Wall warning by initializing variable in negotiation code
8415 [Tobias Weingartner]
8417 Changes with Apache 0.8.12 31 Aug 1995
8419 *) Doesn't pause three seconds after including a CGI script which is
8420 too slow to die off (this is done by not even trying to kill off
8421 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
8422 after the entire document has been processed). [Robert Thau]
8424 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
8426 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
8428 *) Allows .htaccess files to override <Directory> sections naming the
8429 same directory [David Robinson]
8431 *) Removed an efficiency hack in sub_req_lookup_uri which was
8432 causing certain extremely marginal cases (e.g., ScriptAlias of a
8433 *particular* index.html file) to fail. [David Robinson]
8435 *) Doesn't log an error when the requested URI requires
8436 authentication, but no auth header line was supplied by the
8437 client; this is a normal condition (the client doesn't no auth is
8438 needed here yet). [Robert Thau]
8440 *) Behaves more sanely when the name server loses its mind [Sean Welch]
8442 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
8444 *) RFC931 code no longer passes out name of prior clients on current
8445 requests if the current request came from a server that doesn't
8446 do RFC931. [David Robinson]
8448 *) Configuration script accepts "Module" lines with trailing whitespace.
8451 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
8453 *) Cleaned up comments in mod_cgi.c [Robert Thau]
8455 Changes with Apache 0.8.11 24 Aug 1995
8457 *) Wildcard <Directory> specifications work. [Robert Thau]
8459 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
8461 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
8462 the file being requested itself, in addition to the directories leading
8463 up to it. [Robert Thau]
8465 *) Logs access failures due to symlink checks or invalid client address
8466 in the error log [Roy Fielding, Robert Thau]
8468 *) Symlink checks deal correctly with systems where lstat of
8469 "/path/to/some/link/" follows the link. [Thau, Fielding]
8471 *) Doesn't reset DirectoryIndex to 'index.html' when
8472 other directory options are set in a .htaccess file. [Robert Thau]
8474 *) Clarified init code and nuked bogus warning in mod_access.c
8477 *) Corrected several directives in sample srm.conf
8478 --- includes corrections to directory indexing icon-related directives
8479 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
8480 icons for encodings right, and turning on AddEncoding by default).
8483 *) Corrected descriptions of args to AddIcon and AddAlt in command table
8486 *) INSTALL & README mention "contributed modules" directory [Brian
8489 *) Fixed English in the license language... "for for" --> "for".
8492 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
8493 mod_alias.c, merging it almost completely with handling of Alias, and
8494 adding a 'notes' field to the request_rec which allows the CGI module
8495 to discover whether the Alias module has put this request through
8496 ScriptAlias (which it needs to know for back-compatibility, as the old
8497 NCSA code did not check Options ExecCGI in ScriptAlias directories).
8500 Changes with Apache 0.8.10 18 Aug 1995
8502 *) AllowOverride applies to the named directory, and not just
8503 subdirectories. [David Robinson]
8505 *) Do locking for accept() exclusion (on systems that need it)
8506 using a special file created for the purpose in /usr/tmp, and
8507 not the error log; using the error log causes real problems
8508 if it's NFS-mounted; this is known to be the cause of a whole
8509 lot of "server hang" problems with Solaris. [David Robinson;
8510 thanks to Merten Schumann for help diagnosing the problem].
8512 Changes with Apache 0.8.9 12 Aug 1995
8514 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
8516 *) Nested includes see environment variables of the including document,
8517 for NCSA bug-compatibility (some sites have standard footer includes
8518 which try to print out the last-modified date). [Eric Hagberg/Robert
8521 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
8522 URI as a CGI script, even if it would have been treated as something
8523 else if requested directly, for NCSA back-compatibility. (Note that
8524 this means that people who know the name of the script can see the
8525 code just by asking for it). [Robert Thau]
8527 *) New version of dbmmanage script included in support directory as
8530 *) Check if scoreboard file couldn't be opened, and say so, rather
8531 then going insane [David Robinson]
8533 *) POST to CGI works on A/UX [Jim Jagielski]
8535 *) AddIcon and AddAlt commands work properly [Rob Hartill]
8537 *) NCSA server push works properly --- the Arena bug compatibility
8538 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
8539 if you still want the workaround). [Rob Hartill]
8541 *) If client didn't submit any Accept-encodings, ignore encodings in
8542 content negotiation. (NB this will all have to be reworked anyway
8543 for the new HTTP draft). [Florent Guillaume]
8545 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
8547 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
8549 *) Give Redirect priority over Alias, for NCSA bug compatibility
8552 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
8553 paralleling earlier bug fix for CGI [David Robinson]
8555 *) If DBM auth is improperly configured, report a server error and don't
8558 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
8559 it seems to work well enough without it (even in a 10 hits/sec
8560 workout), and the overhead for the locking under A/UX is
8561 alarmingly high (though it is very low on other systems).
8562 [Eric Hagberg, Jim Jagielski]
8564 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
8566 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
8567 Behlendorf/Eric Hagberg]
8569 *) More improvements to default Configuration for A/UX [Jim Jagielski]
8571 *) Compiles clean on NEXT [Rob Hartill]
8573 *) Compiles clean on SGI [Robert Thau]
8575 Changes with Apache 0.8.8 08 Aug 1995
8577 *) SunOS library prototypes now never included unless explicitly
8578 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
8579 people using GNU libc on SunOS are screwed by prototypes for the
8582 (Those who wish to compile clean with gcc -Wall on a standard
8583 SunOS setup need the prototypes, and may obtain them using
8584 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
8585 with nonstandard libraries are presumably competent to make their
8588 *) Strips trailing '/' characters off both args to the Alias command,
8589 to make 'Alias /foo/ /bar/' work.
8591 Changes with Apache 0.8.7 03 Aug 1995
8593 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
8594 [reported by David Robinson]
8596 *) Compiles clean on OSF/1 [David Robinson]
8598 *) Added some of the more recent significant changes (AddLanguage stuff,
8599 experimental LogFormat support) to CHANGES file in distribution root
8602 Changes with Apache 0.8.6 02 Aug 1995
8604 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
8605 (If you actually wanted a conditional GET which bypassed the cache, you
8606 couldn't get it). [Reported by Roy Fielding]
8608 *) Properly terminate headers on '304 Not Modified' replies to conditional
8609 GETs --- no browser we can find cares much, but the CERN proxy chokes.
8610 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
8612 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
8614 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
8615 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
8616 and older versions don't set the __SUNPRO_C preprocessor variable). On
8617 all other systems, these are never used anyway. [Reported by Mark Cox].
8619 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
8621 Changes with Apache 0.8.5 01 Aug 1995
8623 *) Added last-minute configurable log experiment, as optional module
8625 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
8626 properly. (One-line fix to http_protocol.c).
8628 *) Work around bogus behavior when reloading from Netscape.
8629 It's Netscape's bug --- for some reason they expect a request with
8630 If-modified-since: to not function as a conditional GET if it also
8631 comes with Pragma: no-cache, which is way out of line with the HTTP
8632 spec (according to Roy Fielding, the redactor).
8634 *) Added parameter to set maximum number of server processes.
8636 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
8639 *) IdentityCheck bugfix [Chuck Murcko].
8641 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
8643 *) More sample config file corrections; add extension to AddType for
8644 *.asis, move AddType generic description to its proper place, and
8645 fix miscellaneous typos. [ Alexei Kosut ]
8647 *) Deleted the *other* reference to the regents from the Berkeley
8648 legal disclaimer (everyplace).
8650 *) Nuked Shambhala name from src/README; had already cleaned it out
8653 Changes with Apache 0.8.4
8655 *) Changes to server-pool management parms --- renamed current
8656 StartServers to MinSpareServers, created separate StartServers
8657 parameter which means what it says, and renamed MaxServers to
8658 MaxSpareServers (though the old name still works, for NCSA 1.4
8659 back-compatibility). The old names were generally regarded as
8660 too confusing. Also altered "docs" in sample config files.
8662 *) More improvements to default config files ---
8663 sample directives (commented out) for XBitHack, BindAddress,
8664 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
8665 defaults, AddTypes for send-as-is and imagemap magic types, and
8666 improvements to samples for DirectoryIndex [Alexei Kosut]
8668 *) Yet more improvements to default config files --- changes to
8669 Alexei's sample AddLanguage directives, and sample LanguagePriority
8670 [ Florent Guillaume ]
8672 *) Set config file locations properly if not set in httpd.conf
8675 *) Don't escape URIs in internal redirects multiple times; don't
8676 do that when translating PATH_INFO to PATH_TRANSLATED either.
8679 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
8681 Changes with Apache 0.8.3
8683 *) Edited distribution README to *briefly* summarize installation
8684 procedures, and give a pointer to the INSTALL file in the src/
8687 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
8688 recent NCSA distributions.
8690 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
8691 exist for the same directory, use both and don't segfault. [Reported
8694 *) Proper makefile dependencies [David Robinson]
8696 *) Note (re)starts in error log --- reported by Rob Hartill.
8698 *) Only call no2slash() after get_path_info() has been done, to
8699 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
8700 reported by Andrew Wilson, though this one is probably a real bug]
8702 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
8703 dump core when Referer is not supplied. [Randy Terbush]
8705 *) Lightly edited sample config files to refer people to our documentation
8706 instead of NCSA's, and to list Rob McCool as *original* author (also
8707 deleted his old, and no doubt non-functional email address). Would be
8708 nice to have examples of new features...
8710 Changes with Apache 0.8.2 19 Jul 1995
8712 *) Added AddLanuage code [Florent Guillaume]
8714 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
8716 *) All sorts of problems when MultiViews finds a directory. It would
8717 be nice if mod_dir.c was robust enough to handle that, but for now,
8718 just punt. [reported by Brian Behlendorf]
8720 *) Wait for all children on restart, to make sure that the old socket
8721 is gone and we can reopen it. [reported by Randy Terbush]
8723 *) Imagemap module is enabled in default Configuration
8725 *) RefererLog and UserAgentLog modules properly default the logfile
8728 *) Mark Cox's mod_cookies added to the distribution as an optional
8729 module (commented out in the default Configuration, and noted as
8730 an experiment, along with mod_dld). [Mark Cox]
8732 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
8734 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
8736 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
8738 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
8741 Changes with Apache 0.8.1
8743 *) New imagemap module [Randy Terbush]
8745 *) Replacement referer log module with NCSA-compatible RefererIgnore
8746 [Matthew Gray again]
8748 *) Don't mung directory listings with very long filenames.
8751 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
8753 *) New config script. See INSTALL for info. [Robert Thau]
8755 *) Scoreboard mechanism for regulating the number of extant server
8756 processes. MaxServers and StartServers defaults are the same as
8757 for NCSA, but the meanings are slightly different. (Actually,
8758 I should probably lower the MaxServers default to 10).
8760 Before asking for a new connection, each server process checks
8761 the number of other servers which are also waiting for a
8762 connection. If there are more than MaxServers, it quietly dies
8763 off. Conversely, every second, the root, or caretaker, process
8764 looks to see how many servers are waiting for a new connection;
8765 if there are fewer than StartServers, it starts a new one. This
8766 does not depend on the number of server processes already extant.
8767 The accounting is arranged through a "scoreboard" file, named
8768 /tmp/htstatus.*, on which each process has an independent file
8769 descriptor (they need to seek without interference).
8771 The end effect is that MaxServers is the maximum number of
8772 servers on an *inactive* server machine, but more will be forked
8773 off to handle unusually heavy loads (or unusually slow clients);
8774 these will die off when they are no longer needed --- without
8775 reverting to the overhead of full forking operation. There is a
8776 hard maximum of 150 server processes compiled in, largely to
8777 avoid forking out of control and dragging the machine down.
8778 (This is arguably too high).
8780 In my server endurance tests, this mechanism did not appear to
8781 impose any significant overhead, even after I forced it to put the
8782 scoreboard file on a normal filesystem (which might have more
8783 overhead than tmpfs). [Robert Thau]
8785 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
8788 *) Read .htaccess files even in directory with <Directory> section.
8789 (Former incompatibility noted on mailing list, now fixed). [Robert
8792 *) "HEAD /" gives the client a "Bad Request" error message, rather
8793 than trying to send no body *and* no headers. [Cliff Skolnick].
8795 *) Don't produce double error reports for some very obscure cases
8796 mainly involving auth configuration (the "all modules decline to
8797 handle" case which is a sure sign of a server bug in most cases,
8798 but also happens when authentication is badly misconfigured).
8801 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
8802 it's *for*, and this sort of thing really shouldn't be cluttering
8803 up the Makefile). [Robert Thau]
8805 *) Incidental code cleanups in http_main.c --- stop dragging
8806 sa_client around; just declare it where used. [Robert Thau]
8808 *) Another acc-related fix. (It doesn't like const char
8809 in some places...). [Mark Cox]
8811 Changes with Shambhala 0.6.1 13 Jul 1995
8813 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
8814 Also, fixed auth typo in http_protocol.c unmasked by this fix.
8816 *) Compiles clean with acc on SunOS [Paul Sutton]
8818 *) Reordered modules in modules.c so that Redirect takes priority
8819 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
8820 believe it or not, he has an actual site with a ScriptAlias and
8821 a Redirect declared for the *exact same directory*. Even *my*
8822 compatibility fetish wouldn't motivate me to fix this if the fix
8823 required any effort, but it doesn't, so what the hey.
8825 *) Fixed to properly default several server_rec fields for virtual
8826 servers from the corresponding fields in the main server_rec.
8827 [Cliff Skolnick --- 'port' was a particular irritant].
8829 *) No longer kills off nph- child processes before they are
8830 finished sending output. [Matthew Gray]
8832 Changes with Shambhala 0.6.0 10 Jul 1995
8834 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
8835 the connection to the client in an "aborted" state, but otherwise
8836 allow whatever handlers are running to clean up. hard_timeout()s
8837 abort the request in progress completely; anything not tied to some
8838 resource pool cleanup will leak. They're still around because I
8839 haven't yet come up with a more elegant way of handling
8840 timeouts when talking to something that isn't the client. The
8841 default_handler and the dir_handler now use soft timeouts, largely
8842 so I can test the feature. [Robert Thau]
8844 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
8845 the case of log handlers dying prematurely is probably handled VERY
8846 gracelessly at this point, and if the logger stops reading input,
8847 the server will hang. (It is known to correctly restart the
8848 logging process on server restart; this is (should be!) going through
8849 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
8850 script). [Robert Thau]
8852 *) asis files supported (new module). [Robert Thau]
8854 *) IdentityCheck code is compiled in, but has not been tested. (I
8855 don't know anyone who runs identd). [Robert Thau]
8857 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
8858 came in with the request, for NCSA bug-compatibility. [Robert Thau]
8860 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
8862 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
8863 as timeouts are not in scope. [Robert Thau]
8865 *) quoted-string args in config files now handled correctly (doesn't drop
8866 the last character). [Robert Thau; reported by Randy Terbush]
8868 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
8869 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
8871 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
8872 default default type); the former default default behavior when all
8873 type-checkers defaulted had been a core dump. [Paul Sutton]
8875 *) Copy filenames out of the struct dirent when indexing
8876 directories. (On Linux, readdir() returns a pointer to the same
8877 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
8879 Changes with Shambhala 0.5.3 [not released]
8881 *) Default response handler notes "file not found" in the error log,
8882 if the file was not found. [Cliff Skolnick].
8884 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
8885 code no longer sets up bogus PATH_INFO which fakes out the directory
8886 handler). [Cliff Skolnick]
8888 Changes with Shambhala 0.5.2 06 Jul 1995
8890 *) Changes to http_main.c --- root server no longer plays silly
8891 games with SIGCHLD, and so now detects and replaces dying
8892 children. Child processes just die on SIGTERM, without taking
8893 the whole process group with them. Potential problem --- if any
8894 child process refuses to die, we hang in restart.
8895 MaxRequestsPerChild may still not work, but it certainly works
8896 better than it did before this! [Robert Thau]
8898 *) mod_dir.c bug fixes: ReadmeName and HeaderName
8899 work (or work better, at least); over-long description lines
8900 properly terminated. [Mark Cox]
8902 *) http_request.c now calls unescape_url() more places where it
8903 should [Paul Sutton].
8905 *) More directory handling bugs (reported by Cox)
8906 Parent Directory link is now set correctly. [Robert Thau]
8908 Changes with Shambhala 0.5.1 04 Jul 1995
8910 *) Generalized cleanup interface in alloc.c --- any function can be
8911 registered with alloc.c as a cleanup for a resource pool;
8912 tracking of files and file descriptors has been reimplemented in
8913 terms of this interface, so I can give it some sort of a test.
8916 *) More changes in alloc.c --- new cleanup_for_exec() function,
8917 which tracks down and closes all file descriptors which have been
8918 registered with the alloc.c machinery before the server exec()s a
8919 child process for CGI or <!--#exec-->. CGI children now get
8920 started with exactly three file descriptors open. Hopefully,
8921 this cures the problem Rob H. was having with overly persistent
8922 CGI connections. [Robert Thau]
8924 *) Mutual exclusion around the accept() in child_main() --- this is
8925 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
8926 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
8927 This uses fcntl(F_SETLK,...) on the error log descriptor because
8928 flock() on that descriptor won't work on systems which have BSD
8929 flock() semantics, including (I think) Linux 1.3 and Solaris.
8931 This does work on SunOS (when the server is idle, only one
8932 process in the pool is waiting on accept()); it *ought* to work
8933 on the other systems. [Robert Thau]
8935 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
8937 *) sizeof(*sa_client) bugfix from [Rob Hartill]
8939 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
8941 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
8942 be unnecessary if I go to the revised timeout-handling scheme).
8945 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
8946 string) even if none came in with the request. [Robert Thau]
8948 *) CHANGES file added to distribution ;-).
8950 Changes with Shambhala 0.4.5
8952 *) mod_dld --- early dynamic loading support [rst]
8953 *) Add wildcard content handlers for XBITHACK; default_hander now
8954 invoked with that mechanism (as a handler hanging off mod_core) [rst]
8955 *) XBITHACK supported as a wildcard content-handler, and
8956 configurable at run-time (not just at compile time, as in the
8957 "patchy server" releases) [rst]
8959 Changes with Shambhala 0.4.4 30 Jun 1995
8961 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
8962 *) Handle Addtype x/y .z [rst, reported by Cox]
8964 Changes with Shambhala 0.4.3
8966 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
8967 synonymous [rst, terbush]
8969 Changes with Shambhala 0.4.1 28 Jun 1995
8971 *) First-cut virtual host implementation; some refit in the config
8972 reading code, and log management, was necessary to support this [rst]
8973 *) Sub-pool machinery, originally added to avoid excessive storage
8974 allocation on listings of large directories (which turned out to
8975 be the problem that the 0.3 storage accounting was added to
8976 find). Subrequests and mod_dir changed to use subpools. [rst]
8977 *) More memory debugging --- free list consistency checks. [rst]
8978 *) Added err_headers to request_rec, with support elsewhere [rst]
8979 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
8981 Changes with Shambhala 0.3 19 Jun 1995
8983 *) Switch ONE_PROCESS to a runtime command-line option (-X)
8984 *) Don't compile in mod_ai_backcompat by default
8985 *) Switch name of server from Apache to Shambhala in Makefile
8986 *) Add some accounting routines to track memory usage in the pools,
8989 Changes with Shambhala 0.2
8991 *) Set DOCUMENT_ROOT CGI variable
8992 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
8993 *) Add critical section protection to handling of cleanup structures
8995 *) Significant code reorg within the server core to group related
8996 functions together [rst]
8997 *) Correctly handle clients that hang up before sending any request
8999 *) Replace dying child processes. [rst]
9001 Changes with Shambhala 0.1 12 Jun 1995
9003 Major rewrite of the pre-existing "patchy server" codebase, by
9004 Robert Thau (rst). Significant portions of the server code, such
9005 as configuration-file handling and HTTP authentication support,
9006 were ripped out and rewritten from scratch. Code that was not
9007 completely rewritten was significantly altered.
9009 Major changes with this release include:
9011 *) Introduction of the module API; in request handling, the central
9012 machinery just dispatches to various modules, which actually do
9013 most of the work. Configuration handling is similar --- modules
9014 declare their own commands, and the central machinery just
9017 API features from shambhala/0.1 were substantially unchanged in
9018 Apache 1.0 and 1.1. (1.0 API features not yet present in this
9019 release, such as wildcard handlers and subpools, were added in
9020 subsequent Shambhala releases, and were also generally rst's
9023 *) This release included the following modules:
9025 mod_access (access control --- allow and deny directives),
9026 mod_alias (Alias and Redirect commands),
9027 mod_auth (straight HTTP authentication, based on flat-files)
9028 mod_auth_dbm (same, with dbm files)
9029 mod_cgi (CGI scripts and, in this release, ScriptAlias)
9030 mod_common_log (CLF access logs; later renamed mod_log_common)
9031 mod_dir (directory indexing)
9032 mod_include (server-side includes)
9033 mod_mime (AddType directives)
9034 mod_negotiation (content negotiation)
9035 mod_userdir (support for users' public_html directories)
9037 It also included a mod_ai_backcompat, which was a private hack
9038 for back-compatibility with rst's own AI-lab servers.
9040 All of these modules were substantially complete, and functional
9041 or nearly so (a few, which implemented features not in use at
9042 Thau's site, required patches of a few lines).
9044 *) sub-request machinery, to allow modules to determine how other
9045 modules would assign MIME types to a given file, or optionally
9046 serve its content (this is heavily used by mod_dir, mod_include
9047 and mod_negotiation).
9049 *) Resource pool system for keeping track of memory allocated and
9050 files opened in service of a particular request. Much of the
9051 code in the modules (when they weren't rewrites) was adjusted to
9052 replace a pervasive convention of using fixed-size buffers on
9053 the stack with an equally pervasive convention of using memory
9054 allocated with palloc().
9056 *) Reorganization of data structures associated with a given
9057 request to eliminate use of global variables and the troublesome
9058 unmunge_name function (used in NCSA and early Apache releases to
9059 attempt to determine the URI which mapped to a given filename
9060 --- a difficult proposition, given that it is easy to produce
9061 setups in which multiple URIs map to the same file).
9063 *) Source files renamed and rearranged
9065 *) Very simple pre-forking behavior --- parent process forked off a
9066 fixed number of children, and then just waited for SIGHUP.
9068 *) Other more minor changes too numerous to list.
9070 This release included modified versions of a lot of code from the
9071 Apache 0.6.4 public release, plus an early pre-forking patch
9072 codeveloped by Robert Thau and Rob Hartill.
9074 Changes with Apache 0.7.3 20 Jun 1995
9076 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
9077 were incorporated by Rob Hartill on the main branch while Robert Thau
9078 worked on the Shambhala rewrite above. Most were merged into the
9079 Shambala architecture after Apache 0.8.0.
9081 Changes with Apache 0.6.4 13 May 1995
9083 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
9086 Changes with Apache 0.5.1 10 Apr 1995
9088 Changes with Apache 0.4 02 Apr 1995
9090 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
9093 Changes with Apache 0.3 24 Mar 1995
9095 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
9098 Changes with Apache 0.2 18 Mar 1995
9100 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
9101 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
9102 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
