1 Changes with Apache 2.0.12-dev
3 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
4 without ever filling it out. This fixes PR 7271.
5 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
6 Cliff Woolley <cliffwoolley@yahoo.com>]
8 *) Add a couple of GCC attribute tags to printf style functions.
9 [Jon Travis <jtravis@covalent.net>]
11 *) Add the correct language tag for interoperation with the Taiwanese
12 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
14 *) Migrate the perchild MPM to use the new apr signal child, and
15 APR thread functions. [Ryan Bloom]
17 *) Close one copy of the CGI's stdout before creating the new process.
18 The CGI will still have stdout, because we have already dup'ed it.
19 This keeps Apache from waiting forever to send the results of a CGI
20 process that has forked a long-lived child process.
21 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
23 *) Remove the rest of the pthreads functions from the threaded MPM.
24 This requires the APR support for a signal thread that was just
27 *) Make mod_dir use a fixup for sending a redirect to the browser.
28 Before this, we were using a handler, which doesn't make much
29 sense, because the handler wasn't generating any data, it would
30 either return a redirect error code, or DECLINED. This fits the
31 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
33 *) Make the threaded MPM use APR threads instead of pthreads.
36 *) Get mod_tls to the point where it actually appears to work in all cases.
39 *) implement --enable-modules and --enable-mods-shared for "all" and
42 *) Move the threaded MPM to use APR locks instead of pthread locks.
45 *) Rename mpmt_pthread to threaded. This is more in line with the
46 fact that mpmt_pthread shouldn't be using pthreads directly, and
47 it is a smaller name that doesn't tie into anything.
50 *) Rename the module structures so that the exported symbol matches
51 the file name, and it is easier to automate the installation
52 process (generating LoadModule directives from the module filenames).
55 *) Remove the coalesce filter. With the ap_f* functions, this filter
56 is no longer needed. [Ryan Bloom]
58 Changes with Apache 2.0.11
60 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
61 added feature of allowing a uid/gid per child process. If no
62 uid/gid is specified, then Perchild behaves exactly like dexter.
65 *) Get perchild building again. [Ryan Bloom]
67 *) Don't disable threads just because we are using the prefork MPM.
68 If somebody wants to compile without threads, they must now add
69 --disable-threads to the configure command line. [Ryan Bloom]
71 *) Begin to move the calls to update_child_status into common code, so
72 that each individual MPM does not need to update the scoreboard itself.
75 *) Allow mod_tls to compile under Unix boxes where openssl has been
76 installed to the system include files.
77 [Gomez Henri <new-httpd@slib.fr>]
79 *) Cleanup the mod_tls configure process. This should remove any need
80 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
81 configure doesn't check that yet. [Ryan Bloom]
83 *) Add a very early prototype of SSL support (in mod_tls.c). It is
84 vital that you read modules/tls/README before attempting to build
87 *) Fix a potential seg fault on all platforms. David Reid fixed this
88 on BEOS, but the problem could happen anywhere, so we don't want
89 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
91 *) Add new LogFormat directive, %D, to log time it takes to serve a
92 request in microseconds. [Bill Stoddard]
94 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
95 SetOutputFilter. This corresponds nicely with the other Set
96 directives, which operate on containers while the Add* directives
97 tend to work directly on extensions. [Ryan Bloom]
99 *) Cleanup the header handling a bit. This uses the apr_brigade_*
100 functions for the buffering so that we don't need to compute
101 the length of the headers before we actually create the header
104 *) Allow filters to buffer data using the ap_f* functions. These have
105 become macros that resolve directly to apr_brigade_*.
108 *) Get the Unix MPM's to do a graceful restart again. If we are going
109 to register a cleanup with ap_cleanup_scoreboard, then we have to
110 kill the cleanup with the same function, and that function can't be
113 *) Install all required header files. Without these, it was not
114 possible to compile some modules outside of the server.
117 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
118 forward from 1.3 to 2.0, we missed a single line, which broke regex
119 aliases. [Ryan Bloom]
121 *) We have a poor abstraction in the protocol. This is a temporary
122 hack to fix the bug, but it will need to be fixed for real. If
123 we find an error while sending out a custom error response, we back
124 up to the first non-OK request and send the data. Then, when we send
125 the EOS from finalize_request_protocol, we go to the last request,
126 to ensure that we aren't sending an EOS to a request that has already
127 received one. Because the data is sent on a different request than
128 the EOS, the error text never gets sent down the filter stack. This
129 fixes the problem by finding the last request, and sending the data
130 with that request. [Ryan Bloom]
132 *) Make the server status page show the correct restart time, and
133 thus the proper uptime. [Ryan Bloom]
135 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
136 should reduce the amount of duplicate code that is required to
137 create CGI processes.
138 [Paul J. Reder <rederpj@raleigh.ibm.com>]
140 *) ap_new_connection() closes the socket and returns NULL if a socket
141 call fails. Usually this is due to a connection which has been
142 reset. [Jeff Trawick]
144 *) Move the Apache version information out of httpd.h and into release.h.
145 This is in preparation for the first tag with the new tag and release
148 *) Begin restructuring scoreboard code to enable adding back in
149 the ability to use IPC other than shared memory.
150 Get mod_status working on Windows again. [Bill Stoddard]
152 *) Make mod_status work with 2.0. This will work for prefork,
153 mpmt_pthread, and dexter. [Ryan Bloom]
155 *) Correct a typo in httpd.conf.
156 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
158 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
160 *) Get the correct IP address if ServerName isn't set and we can't
161 find a fully-qualified domain name at startup.
162 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
164 *) Make mod_cgid work with SuExec. [Ryan Bloom]
166 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
167 'extra' stat's for user/group since they should never occur, and now
168 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
169 volumes. [William Rowe]
171 *) Adopt apr features to simplify mod_includes. This changes the
172 behavior of the USER_NAME variable, unknown uid's are now reported
173 as USER_NAME="<unknown>" rather than the old user#000 result.
174 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
176 *) Adopt apr features for simplifing mod_userdir, and accept the new
177 Win32/OS2 exceptions without hiccuping. [William Rowe]
179 *) Replace configure --with-optim option by using and saving the
180 environment variable OPTIM instead. This is needed because configure
181 options do not support multiple flags separated by spaces.
184 *) Fix some byterange handling. If we get a byte range that looks like
185 "-999999" where that is past the end of the file, we should return
186 a PARTIAL CONTENT status code, and return the whole file as one big
187 byterange. This matches the 1.3 handling now. [Ryan Bloom]
189 *) Make the error bucket a real meta-data bucket. This means that the
190 bucket length is 0, and a read returns NULL data. If one of these
191 buckets is passed down after the headers are sent, this data will
192 just be ignored. [Greg Stein]
194 *) The prefork MPM wasn't killing child processes correctly if a restart
195 signal was received while the process was serving a request. The child
196 process would become the equivalent of a second parent process. If
197 we break out of the accept loop, then we need to do die after cleaning
198 up after ourselves. [Ryan Bloom]
200 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
201 restarts. [Ryan Bloom]
203 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
204 the most optimal APR_FINFO_wanted bits. This spares Win32 from
205 performing very expensive owner, group and permission lookups
206 and allows the server to function until these apr_finfo_t fields
207 are implemented under Win32. [William Rowe]
209 *) Support for typedsafe optional functions - that is functions exported by
210 optional modules, which, therefore, may or may not be present, depending
211 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
212 for sample code. [Ben Laurie]
214 *) filters can now report an HTTP error to the server. This is done
215 by sending a brigade where the first bucket is an error_bucket.
216 This bucket is a simple bucket that stores an HTTP error and
217 a string. Currently the string is not used, but it may be needed
218 to output an error log. The http_header_filter will find this
219 bucket, and output the error text, and then return
220 AP_FILTER_ERROR, which informs the server that the error web page
221 has already been sent. [Ryan Bloom]
223 *) If we get an error, then we should remove all filters except for
224 those critical to serving a web page. This fixes a bug, where
225 error pages were going through the byterange filter, even though
226 that made no sense. [Ryan Bloom]
228 *) Relax the syntax checking of Host: headers in order to support
229 iDNS. PR#6635 [Tony Finch]
231 *) Cleanup the byterange filter to use the apr_brigade_partition
232 and apr_bucket_copy functions. This removes a lot of very messy
233 code, and hopefully makes this filter more stable.
236 *) Remove AddModule and ClearModuleList directives. Both of these
237 directives were used to ensure that modules could be enabled
238 in the correct order. That requirement is now gone, because
239 we use hooks to ensure that modules are in the correct order.
242 *) When SuExec is specified, we need to add it to the list of
243 targets to be built. If we don't, then any changes to the
244 configuration won't affect SuExec, unless 'make suexec' is
245 specifically run. [Ryan Bloom]
247 *) Cleaned out open_file from mod_file_cache, as apr now accepts
248 the APR_XTHREAD argument to open a file for consumption by
249 parallel threads on win32. [William Rowe]
251 *) Correct a bug in determining when we follow symlinks. The code
252 expected a stat -1 result, not an apr_status_t positive error.
253 Also check if the APR_FINFO_USER fields are valid before we
254 follow the link. [William Rowe]
256 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
257 mpm_common.c. These functions are only valid on some platforms,
258 so they should not be in the main-line code. [Ryan Bloom]
260 *) Remove ap_chdir_file(). This function is not thread-safe,
261 and nobody is currently using it. [Ryan Bloom]
263 *) Do not try to run make depend if there are no .c files in the
264 current directory, doing so makes `make depend` fail.
267 *) Update highperformance.conf to work with either prefork or
268 pthreads mpms. [Greg Ames]
270 *) Stop checking to see if this is a pipelined request if we know
271 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
272 This keeps us from making an extra read call when serving a 1.0
273 request. [Ryan Bloom and Greg Stein]
275 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
276 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
277 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
279 *) Fix the RFC number mentioned when complaining about a missing
280 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
282 *) Fix an endless loop in ab which occurred when ab was posting
283 and the server dropped the connection unexpectedly.
286 *) Fix a segfault while handling request bodies in ap_http_filter().
287 This problem has been seen with mod_dav usage as well as with
288 requests where the body was just being discarded. [Jeff Trawick]
290 *) Some adjustment on the handling and automatic setting (via
291 hints.m4) of various compilation flags (eg: CFLAGS). Also,
292 add the capability to specify flags (NOTEST_CFLAGS and
293 NOTEST_LDFLAGS) which are used to compile Apache, but
294 not used during the configuration process. Useful for
295 flags like "-Werror". [Jim Jagielski]
297 *) Stop using environment variables to force debug mode or
298 no detach. We now use the -D command line argument to
299 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
300 [Greg Stein, Ryan Bloom]
302 *) Change handlers to use hooks. [Ben Laurie]
304 *) Stop returning copies of filenames from both apr_file_t and
305 apr_dir_t. We pstrdup the filenames that we store in the
306 actual structures, so we don't need to pstrdup the strings again.
309 *) mod_cgi: Fix some problems where the wrong error value was being
310 traced. [Jeff Trawick]
312 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
315 *) Add generic hooks. [Ben Laurie]
317 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
319 *) Fix a segfault caused by mod_ext_filter when the external filter
320 program does not exist. [Jeff Trawick]
322 *) Fix an output truncation error when on an HTTP >= 1.0 request an
323 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
324 was served through mod_charset_lite (or anything else that would
325 create a transient bucket in this size range). ap_bucket_make_heap()
326 silently failed (fixed), transient_setaside() discovered it, but
327 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
329 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
330 is that some browsers send extra lines at the end of POST requests, and
331 we don't want to delay sending data back to the user just because the
332 browser isn't well behaved. [Ryan Bloom]
334 *) Get SuEXEC working again. We can't send absolute paths to suExec
335 because it refuses to execute those programs. SuEXEC also wasn't
336 always recognizing configuration changes made using the autoconf
339 *) Allow the buildconf process to find the config.m4 files in the correct
340 order. Basically, we can now name config.m4 files as config\d\d.m4,
341 and we will sort them correctly when inserting them into the build
342 process. [Ryan Bloom]
344 *) Get mod_cgid to use apr calls for creating the actual CGI process.
345 This also allows mod_cgid to use ap_os_create_priviledged_process,
346 thus allowing for SuExec execution from mod_cgid. Currently, we do
347 not support everything that standard SuExec supports, but at least
348 it works minimally now. [Ryan Bloom]
350 *) Allow SuExec to be configured from the ./configure command line.
353 *) Update some of the docs in README and INSTALL to reflect some of
354 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
356 *) If we get EAGAIN returned from the call to apr_sendfile, then we
357 need to call sendfile again. This gets us serving large files
358 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
360 *) Get the support programs building cleanly again.
361 [Cliff Woolley <cliffwoolley@yahoo.com>]
363 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
364 current directory logic now backs up over bin/ to determine the
365 server root from the Apache.exe path.
367 *) Apache/Win32 now follows the standard conventions of mod_foo.so
368 loadable modules, dynamic libs are all named libfoo.dll, and the
369 makefile.win populates the include, lib and libexec directories.
371 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
372 Apache gets IPv6 listening sockets by default. Additionally, the
373 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
374 numeric address strings (e.g., "Listen [fe80::1]:8080").
377 *) Modify the install directory layout. Modules are now installed in
378 modules/. Shared libraries should be installed in libraries/, but
379 we don't have any of those on Unix yet. All install directories
380 are modifyable at configure time. [Ryan Bloom]
382 *) Install all header files in the same directory on Unix. [Ryan Bloom]
384 *) Get the functions in server/linked into the server, regardless of
385 which modules linked into the server. This uses the same hack
386 for Apache that we use for APR and apr-util to ensure all of the
387 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
388 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
389 the scripts a bit easier.
392 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
393 on the query, and remove IPv4 dependencies. [Jeff Trawick]
395 *) Get all of the auth modules to the point that they will install and
396 be loadable into the server. Our new build/install mechanism expects
397 that all modules will have a common name format. The auth modules
398 didn't use that format, so we didn't install them properly.
401 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
402 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
404 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
406 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
407 after the end of the response. [Ryan Bloom]
409 *) Get byterange requests working with responses that do not have a
410 content-length. Because of the way byterange requests work, we have to
411 have all of the data before we can actually do the byterange, so we
412 can compute the content-length in the byterange filter.
415 *) Get exe CGI's working again on Windows.
418 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
419 they keep track of whether or not their post config hook has been
420 called before. Instead of a static variable (which is replaced when
421 the DSO is loaded a second time), use userdata in the process pool.
424 Changes with Apache 2.0a9
426 *) Win32 now requires perl to complete the final install step for users
427 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
428 and installs the conf, htdocs and htdocs/manual directories.
431 *) Make mod_include use a hash table to associate directive tags with
432 functions. This allows modules to implement their own SSI tags easily.
433 The idea is simple enough, a module can insert it's own tag and function
434 combination into a hash table provided by mod_include. While mod_include
435 parses an SSI file, when it encounters a tag in the file, it does a
436 hash lookup to find the function that implements that tag, and passes
437 all of the relevant data to the function. That function is then
438 responsible for processing the tag and handing the remaining data back
439 to mod_include for further processing.
440 [Paul J. Reder <rederpj@raleigh.ibm.com>]
442 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
443 fewer parameters: the local and remote socket addresses were removed
444 from the parameter list because all required information is available
445 via the APR socket. [Jeff Trawick]
447 *) Distribution directory structure reorganized to reflect a
448 normal source distribution with external install targets.
451 *) The MPMs that need multiple segments of shared memory now create
452 two apr_shmem_t variables, one for each shared memory allocation.
453 the problem is that we can't determine how much memory will be required
454 for shared memory allocations once we try to allocate more than one
455 variable. The MM code automatically aligns the shared memory allocations,
456 so we end up needing to pad the amount of shared memory we want based
457 on how many variables will be allocated out of the shared memory segment.
458 It is just easier to create a second apr_shmem_t variable, and two
462 *) Cleanup the export list a bit. This creates a single unified list of
463 functions exported by APR. The export list is generated at configure
464 time, and that list is then used to generate the exports.c file.
465 Because of the way the export list is generated, we only export those
466 functions that are valid on the platform we are building on.
469 *) Enable logging the cookie with mod_log_config
470 [Sander van Zoest <sander@covalent.net>]
472 *) Fix a segfault in mod_info when it reaches the end of the configuration.
475 *) Added lib/aputil/ as a placeholder for utility functions which are not
476 specific to the Apache HTTP Server (but do not make sense with APR).
477 The first utility is "apu_dbm": a set of functions to work with DBM
478 files. This first version can be compiled for SDBM or GDBM databases.
481 *) Complete re-write of mod_include. This makes mod_include a filter that
482 uses buckets directly. This has now served the FAQ correctly.
483 [Paul Reder <rederpj@raleigh.ibm.com>]
485 *) Allow modules to specify the first filter in a sub_request when
486 making the sub_request. This keeps modules from having to change the
487 output_filter immediately after creating the sub-request, and therefore
488 skip the sub_req_output_filter. [Ryan Bloom]
490 *) Update ab to accept URLs with IPv6 literal address strings (in the
491 format described in RFC 2732), and to build Host header fields in
492 the same format. This allows IPv6 literal address strings to be
493 used with ab. This support has been tested against Apache 1.3 with
494 the KAME patch, but Apache 2.0 does not yet work with this format
495 of the Host header field. [Jeff Trawick]
497 *) Accomodate an out-of-space condition in the piped logs and the
498 rotatelogs.c code, and no longer churn log processes for this
499 condition. [Victor J. Orlikowski]
501 *) Add support for partial writes with apr_sendfile() to core_output_filter.
504 Changes with Apache 2.0a8
506 *) Add a directive to mod_mime so that filters can be associated with
510 *) Get multi-views working again. We were setting the path_info
511 field incorrectly if we couldn't find the specified file.
514 *) Fix 304 processing. The core should never try to send the headers
515 down the filter stack. Always, just setup the table in the request
516 record, and let the header filter convert it to data that is ready
520 *) More fixes for the proxy. There are still bugs in the proxy code,
521 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
525 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
528 *) APR: Add new apr_getopt_long function to handle long options.
529 [B. W. Fitzpatrick <fitz@red-bean.com>]
531 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
532 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
533 hostname resolution/address string parsing and building
534 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
535 of one of the apr_sockaddr_t structures for a socket. Change
536 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
538 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
539 I have proxied pages with it, cleanup will commence soon.
542 *) Make the proxy work with filters. This isn't perfect, because we
543 aren't dealing with the headers properly. [Ryan Bloom]
545 *) Do not send a content-length iff the C-L is 0 and this is a head
546 request. [Ryan Bloom]
548 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
549 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
551 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
553 *) Get the default_handler to stop trying to deal with HEAD requests.
554 The idea is to let the content-length filter compute the C-L before
555 we try to send the data. If we can get the C-L correctly, then we
556 should send it in the HEAD response.
559 *) The Header filter can now determine if a body should be sent based
560 on r->header_only. The general idea of this is that if we delay
561 deciding to send the body, then we might be able to compute the
562 content-length correctly, which will help caching proxies to cache
563 our data better. Any handler that doesn't want to try to compute
564 the content-length can just send an EOS bucket without data and
565 everything will just work.
568 *) Add the referer to the error log if one is available.
569 [Markus Gyger <mgyger@itr.ch>]
571 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
572 change, the root of the configuration tree has been exposed to modules
574 [Ryan Morgan <rmorgan@covalent.net>]
576 *) Get the core_output_filter to use the bucket interface directly.
577 This keeps us from calling the content-length filter multiple times
578 for a simple static request.
581 *) We are sending the content-type correctly now.
582 [Ryan Bloom and Will Rowe]
584 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
585 a bogus bytes-sent value when the only thing being sent was trailers
586 and writev() returned an error (or EAGAIN). [Jeff Trawick]
588 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
589 hints file to determine which platforms define
590 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
593 *) APR: add apr_get_home_directory() [Jeff Trawick]
595 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
597 *) Not all platforms have INADDR_NONE defined by default. Apache
598 used to make this check and define INADDR_NONE if appropriate,
599 but APR needs the check too, and I suspect other applications will
600 as well. APR now defines APR_INADDR_NONE, which is always a valid
601 value on all platforms.
602 [Branko Èibej <brane@xbc.nu>]
604 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
605 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
607 *) Relax the syntax checking of Host: headers in order to support
608 iDNS. PR#6635 [Tony Finch]
610 *) When reading from file buckets we convert to an MMAP if it makes
611 sense. This also simplifies the default handler because the
612 default handler no longer needs to try to create MMAPs.
615 *) BUFF has been removed from the main server. The BUFF code will remain
616 in the code until it has been purged from the proxy module as well.
619 *) Byteranges have been completely re-written to be a filter. This
620 has been tested, and I believe it is working correctly, but it could
621 doesn't work for the Adobe Acrobat plug-in. The output almost matches
622 the output from 1.3, the only difference being that 1.3 includes
623 a content-length in the response, and this does not.
626 *) APR read/write functions and bucket read functions now operate
627 on unsigned integers, instead of signed ones. It doesn't make
628 any sense to use signed ints, because we return the error codes,
629 so if we have an error we should report 0 bytes read or written.
632 *) Always compute the content length, whether it is sent or not.
633 The reason for this, is that it allows us to correctly report
634 the bytes_sent when logging the request. This also simplifies
635 content-length filter a bit, and fixes the actual byte-reporing
636 code in mod_log_config.c
639 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
640 it says, because it was only used by EOS and FLUSH buckets. Since
641 neither of those are required at the end of a brigade, this was
642 really signifying FLUSH_THE_DATA, but that can be determined better
643 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
644 buckets now return a length of 0, which is actually the amount of data
645 read, so they make more sense.
648 *) Allow the core_output_filter to save some data past the end of a
649 request. If we get an EOS bucket, we only send the data if it
650 makes sense to send it. This allows us to pipeline request
651 responses. As a part of this, we also need to allocate mmap
652 buckets out of the connection pool, not the request pool. This
653 allows the mmap to outlive the request.
656 *) Make blocking and non-blocking bucket reads work correctly for
657 sockets and pipes. These are the only bucket types that should
658 have non-blocking reads, because the other bucket types should
659 ALWAYS be able to return something immediately.
662 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
663 server, but use Ctrl+Break to initiate a graceful restart
664 instead of duplicating behavior. [John Sterling]
666 *) Patch mod_autoindex to set the Last-Modified header based on
667 the directory's mtime, and add the ETag header. [William Rowe]
669 *) Merge the 1.3 patch to add support for logging query string in
670 such a way that "%m %U%q %H" is the same as "%r".
673 *) Port three log methods from mod_log_config 1.3 to 2.0:
674 CLF compliant '-' byte count, method and protocol.
677 *) Add a new LogFormat directive, %c, that will log connection
678 status at the end of the response as follows:
679 'X' - connection aborted before the response completed.
680 '+' - connection may be kept-alive by the server.
681 '-' - connection will be closed by the server.
684 *) Expand APR for WinNT to fully accept and return utf-8 encoded
685 Unicode file names and paths for Win32, and tag the Content-Type
686 from mod_autoindex to reflect that charset if the the feature
687 macro APR_HAS_UNICODE_FS is true. [William Rowe]
689 *) Compute the content length (and add appropriate header field) for
690 the response when no content length is available and we can't use
691 chunked encoding. [Jeff Trawick]
693 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
694 so that content input filters get dechunked data when using
695 the default handler. Also removed REQUEST_CHUNKED_PASS.
698 *) Add mod_ext_filter as an experimental module. This module allows
699 the administrator to use external programs as filters. Currently,
700 only filtering of output is supported. [Jeff Trawick]
702 *) Most Apache functions work on EBCDIC machines again, as protocol
703 data is now translated (again). [Jeff Trawick]
705 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
706 the EBCDIC support. They are noops on ASCII machines, so this
707 type of translation doesn't have to be surrounded by #ifdef
708 CHARSET_EBCDIC. [Jeff Trawick]
710 *) Fix mod_include. tag commands work again, and the server will
711 send the FAQ again. This also allows mod_include to set aside
712 buckets that include partial buckets.
713 [Ryan Bloom and David Reid]
715 *) Add suexec support back. [Manoj Kasichainula]
717 *) Lingering close now uses the socket directly instead of using
718 BUFF. This has been tested, but since all we can tell is that it
719 doesn't fail, this needs to be really hacked on.
722 *) Allow filters to modify headers and have those headers be sent to
723 the client. The idea is that we have an http_header filter that
724 actually sends the headers to the network. This removes the need
725 for the BUFF to send headers.
728 *) Charset translation: mod_charset_lite handles translation of
729 request bodies. Get rid of the xlate version of ap_md5_digest()
730 since we don't compute digests of filtered (e.g., translated)
731 response bodies this way anymore. (Note that we don't do it at
732 all at the present; somebody needs to write a filter to do so.)
735 *) Input filters and ap_get_brigade() now have a input mode parameter
736 (blocking, non-blocking, peek) instead of a length parameter.
739 *) Update the mime.types file to the registered media types as
740 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
743 *) Namespace protect some macros declared in ap_config.h
746 *) Support HTTP header line folding with input filtering.
749 *) Mod_include works again. This should still be re-written, but at
750 least now we can serve an SHTML page again.
753 *) Begin to remove BUFF from the core. Currently, we keep a pointer
754 to both the BUFF and the socket in the conn_rec. Functions that
755 want to use the BUFF can, functions that want to use the socket,
756 can. They point to the same place.
759 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
760 [Tomas "Ögren" <stric@ing.umu.se>]
762 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
763 associated pool goes away. (APR pipes on OS/2 were already had this
764 logic.) This resolvs a fatal file descriptor leak with CGIs.
767 *) The final line of the config file was not being read if there was
768 no \n at the end of it. This was caused by apr_fgets returning
769 APR_EOF even though we had read valid data. This is solved by
770 making cfg_getline check the buff that was returned from apr_fgets.
771 If apr_fgets return APR_EOF, but there was data in the buf, then we
772 return the buf, otherwise we return NULL.
775 *) Piped logs work again in the 2.0 series.
778 *) Restore functionality broken by the mod_rewrite security fix:
779 rewrite map lookup keys and default values are now expanded
780 so that the lookup can depend on the requested URI etc.
781 PR #6671 [Tony Finch]
783 *) Tighten up the syntax checking of Host: headers to fix a
784 security bug in some mass virtual hosting configurations
785 that can allow a remote attacker to retrieve some files
786 on the system that should be inaccessible. [Tony Finch]
788 *) Add a pool bucket type. This bucket is used for data allocated out
789 of a pool. If the pool is cleaned before the bucket is destroyed, then
790 the data is converted to a heap bucket, allowing it to survive the
794 *) Add a flush bucket. This allows modules to signal that the filters
795 should all flush whatever data they currently have. There is no way
796 to actually force them to do this, so if a filter ignores this bucket,
797 that's life, but at least we can try with this.
800 *) Add an output filter for sub-requests. This filter just strips the
801 EOS bucket so that we don't confuse the main request's core output
802 filter by sending multiple EOS buckets. This change also makes sub
803 requests start to send EOS buckets when they are finished.
806 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
807 makes ap_bucket_destroy a return void, which is okay because it
808 used to always return APR_SUCCESS, and nobody ever checked its
810 [Cliff Woolley <cliffwoolley@yahoo.com>]
812 *) Remove the index into the bucket-type table from the buckets
813 structure. This has now been replaced with a pointer to the
814 bucket_type. Also add some macros to test the bucket-type.
817 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
818 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
819 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
820 All _VAR_ flavors changes to _DATA to be absolutely clear.
823 *) Add support for /, //, //servername and //server/sharename
824 parsing of <Directory> blocks under Win32 and OS2.
825 [Tim Costello, William Rowe, Brian Harvard]
827 *) Remove the function pointers from the ap_bucket type. They have been
828 replaced with a global table. Modules are allowed to register bucket
829 types and use then use those buckets.
832 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
833 once we finish writing the request body to the cgi child process;
834 otherwise, the client doesn't hit EOF on stdin. Small request bodies
835 worked without this change (for reasons I don't understand), but large
836 ones didn't. [Jeff Trawick]
838 *) Remove file bucket specific information from the ap_bucket type.
839 This has been moved to a file_bucket specific type that hangs off
840 the data pointer in the ap_bucket type.
843 *) Input filtering now has a third argument. This is the amount of data
844 to read from lower filters. This argument can be -1, 0, or a positive
845 number. -1 means give me all the data you have, I'll deal with it and
846 let you know if I need more. 0 means give me one line and one line
847 only. A positive number means I want no more than this much data.
849 Currently, only 0 and a positive number are implemented. This allows
850 us to remove the remaining field from the conn_rec structure, which
854 *) Big cleanup of the input filtering. The goal is that http_filter
855 understands two conditions, headers and body. It knows where it is
856 based on c->remaining. If c->remaining is 0, then we are in headers,
857 and http_filter returns a line at a time. If it is not 0, then we are
858 in body, and http_filter returns raw data, but only up to c->remaining
859 bytes. It can return less, but never more.
860 [Greg Ames, Ryan Bloom, Jeff Trawick]
862 *) mod_cgi: Write all of the request body to the child, not just what
863 the kernel would accept on the first write. [Jeff Trawick]
865 *) Back out the change that moved the brigade from the core_output_filters
866 ctx to the conn_rec. Since all requests over a given connection
867 go through the same core_output_filter, the ctx pointer has the
871 *) Fix another bug in the send_the_file() read/write loop. A partial
872 send by apr_send would cause unsent data in the read buffer to
873 get clobbered. Complete making send_the_file handle partial
874 writes to the network.
877 *) Fix a couple of type fixes to allow compilation on AIX again
878 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
880 *) Fix bug in send_the_file() which causes offset to be ignored
881 if there are no headers to send.
884 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
885 filter. Useful for supporting Windows 9* with a binary
886 compiled on Windows NT.
889 Changes with Apache 2.0a7
891 *) Reimplement core_output_filter to buffer/save bucket brigades
892 across multiple calls to the core_filter. The brigade will be
893 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
894 thresholds are hit or the EOS bucket is received.
897 *) Create experimental filter (buffer_filter) that coalesces bytes
898 into one large buffer before invoking the next filter in the
899 chain. This filter is particularly useful with the current
900 implementation of mod_autoindex when it inserted above the
901 chunk_filter. mod_autoindex generates a lot of brigades that
902 containing buckets holding just a few bytes each. The
903 buffer_filter coalesces these buckets into a single large bucket.
906 *) Add apr_sendfile() support into the core_output_filter.
909 *) Add apr_sendv() support into the core_output_filter.
912 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
913 [Mike Abbott <mja@sgi.com>]
915 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
916 make much sense, because Apache uses buckets instead of BUFFs now.
919 *) send_the_file now falls back to a read/write loop on platforms that
920 do not have sendfile.
921 [Ryan Bloom and Brian Havard]
923 *) Install apachectl correctly, and substitute the proper values so
924 that it works again. [Ryan Bloom]
926 *) Better(??) handle platforms that lack sendfile().
929 *) APR now has UUID generation/formatting/parsing support.
932 *) Begin the http_filter. This is an input filter that understands
933 the absolute basic amount required to parse an HTTP Request. The
934 goal is to be able to split headers from request body before passing
935 the data back to the other filters.
938 *) Bring forward from 1.3.13 the config directory implementation
941 *) install apxs if it is created
944 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
945 conversions. [William Rowe]
947 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
948 ap_add_output_filter(). [Jeff Trawick]
950 *) Multiple build and configuration fixes
953 -add datadir and localstatedir substitutions
955 -fix logfilename misspelling
956 -fix evaluation of installation dir variables and
957 -replace $foobar by $(foobar) to be usefull in the makefile
961 -add rules for cross-compiling in rules.mk. Okay, rule to check for
962 $CC_FOR_BUILD is still missing
963 -use CHECK_TOOL instead of CHECK_PROG for ranlib
964 -add missing "AR=@AR@" to severaly Makefile.in's
965 -cache result for "struct rlimit"
966 -compile all helper programs with native and cross compiler
967 and use the native version to generate header file
968 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
970 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
972 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
974 *) Fix a bug where a client which only sends \n to delimit header
975 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
976 message. Start working on ebcdic co-existance with input
978 [William Rowe, Greg Ames]
980 *) If mod_so is enabled in the server always create libexec, even
981 if there are no modules installed in this directory. This is a
982 requirement for APXS to work correctly.
985 *) Connection oriented output filters are now stored in the
986 conn_rec instead of the request_rec. This allows us to add the
987 output filter in the pre-connection phase instead of the
988 post_read_request phase, which keeps us from trying to write an
989 error page before we have a filter to write to the network.
990 [Ryan Bloom, Jeff Trawick, and Greg Ames]
992 *) Cleaning up an mmap bucket no longer deletes the mmap. An
993 mmap can be used across multiple buckets (default_handler with
994 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
995 the mmap itself can't be associated with the bucket.
998 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
1001 *) Radical surgery to improve mod_isapi support under Win32.
1002 Includes a number of newer ServerSupportFunction calls, support
1003 for ReadClient (in order to retrieve POSTs greater than 48KB),
1004 and general bug fixes to more reliably load ISAPI .dll's and
1005 prevent leaking handle resources. Note: There are still
1006 discrepancies between IIS's and Apache's ServerVariables, and
1007 async calls are still not supported. Additional warnings are
1008 logged to facilitate debugging of unsupported ISAPI calls.
1011 *) Add input filtering to Apache. The basic idea for the input
1012 filters is the same as the ideas for output filters. The biggest
1013 difference is that instead of calling ap_pass_brigade, ap_get_brigade
1014 should be called, and the order of execution for the filter itself is
1015 different. When writing an output filter, a brigade is passed in,
1016 and filters operate directly on that brigade, when done, they call
1017 ap_pass_brigade. Input filters are the exact opposite. Because input
1018 is not a push operation, filters first call ap_get_brigade. When this
1019 function returns, the input filter will be left with a valid brigade.
1020 The input filter should then operate on the brigade, and return.
1023 *) Fix building on BSD/OS using its native make. The build system
1024 falls back to the BSD .include directive on that host platform.
1027 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
1028 SHA1 and plaintext password encodings. Make feature tests a
1029 bit more flexible. [William Rowe]
1031 *) Charset translation: mod_charset_lite handles output content
1032 translation in a filter. mod_charset_lite no longer ignores
1033 subrequests. A bunch of cruft related to BUFF's support for
1034 translating request and response bodies was removed.
1037 *) Move the addition of the CORE filter to the post_read_request
1038 hook in http_core.c. This removes the need to add the filter in
1039 multiple places and allows for an SSL module to be added much
1040 simpler. [Ryan Bloom]
1042 *) Fix a security problem that affects certain configurations of
1043 mod_rewrite. If the result of a RewriteRule is a filename that
1044 contains expansion specifiers, especially regexp backreferences
1045 $0..$9 and %0..%9, then it may be possible for an attacker to
1046 access any file on the web server. [Tony Finch]
1048 *) Fix a bug where errors that are detected during early request parsing
1049 don't produce visible HTTP error messages at the browser, because
1050 the core_filter wasn't present. [Greg Ames]
1052 *) Provide apr_socklen_t as a portability aid.
1053 [Victor J. Orlikowski]
1055 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
1056 as well as a comment arg to the add, adduser and update cmds.
1057 update allows the user to clear or preserve pw/groups/comment.
1058 Fixed a bug in dbmmanage that prevented the check option from
1059 parsing a password followed by :group... text. Corrected the
1060 seed calcualation for Win32 systems, and added -lsdbm support.
1063 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
1066 *) Avoid a segfault when parsing .htaccess files. An
1067 uninitialized tree pointer was passed to ap_build_config().
1070 *) Change the way that inet_addr & inet_network are checked for
1071 in APR's configure process to allow BeOS BONE to correctly
1072 find them. With this change BeOS BONE now builds from source
1073 with no problems. [David Reid]
1075 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
1076 the end of the parameters to execve() was stored in the wrong
1077 location, overlaying the storage beyond the newargs[] array and
1078 also passing uninitialized storage to execve(), which would
1079 sometimes fail with EFAULT. [Jeff Trawick]
1081 *) Fix a bug parsing configuration file containers. With a sequence
1082 like this in the config file
1084 <IfModule mod_kilroy.c>
1087 <IfModule mod_lovejoy.c>
1092 the second container would be terminated at the blank line due to
1093 sediment in the buffer from reading the prior </IfModule> and an
1094 error message would be generated for the real </IfModule> for the
1095 second container. Also due to this problem, any two characters
1096 could be used for "</" in the close of a container.
1099 *) ap_add_filter prototype changed to remove the ctx pointer. The
1100 pointer still remains in the filter structure, but it can not be
1101 a part of the ap_add_filter prototype. The reason is that when
1102 the core uses AddFilter to add a filter to the stack it doesn't
1103 know how to allocate the ctx pointer, or even how much memory should
1104 be allocated. The filters will have to be responsible for allocating
1105 the ctx memory when they need it.
1108 *) Add an AddFilter directive. This directive takes a list of filters
1109 that should be activated for the requested resource.
1112 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
1113 some other platforms). [Jeff Trawick]
1115 *) Modify mod_include to be a filter. Currently, it has only been tested
1116 on actual files, but it should work for CGI scripts too.
1119 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
1120 writes. apr_flush() for Unix: handle interrupted writes.
1123 *) NameVirtualHost can now take "*" as an argument instead of
1124 an IP address. This allows you to create a purely name-based
1125 virtual hosting server that does not have any IP addresses in
1126 the configuration file and which ignores the local address
1127 of any connections. PR #5595, PR #4455 [Tony Finch]
1129 *) Fix some compile warnings in mod_mmap_static.c
1130 [Mike Abbott <mja@sgi.com>]
1132 *) Fix chunking problem with CGI scripts. The general problem was that
1133 the CGI modules were adding an EOS bucket and then the core added an
1134 EOS bucket. The chunking filter finalizes the chunked response when it
1135 encounters an EOS bucket. Because two EOS buckets were sent, we
1136 finalized the response twice. The fix is to make sure we only send one
1137 EOS, by utilizing a flag in the request_rec.
1140 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
1141 and Win32. Previously, the first read from an apr_file_t set up via
1142 apr_put_os_file() would return a '\0'. [Jeff Trawick]
1144 *) Mod_cgid now creates a single element bucket brigade, with a pipe
1145 bucket, instead of using BUFF's and ap_r*.
1148 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
1149 [Mike Abbott <mja@sgi.com>]
1151 *) Remove ap_bopenf from buff code. This required modifying the file_cache
1152 code to use APR file's directly instead of going through BUFFs.
1155 *) Fix compile break on some platforms for mod_mime_magic.c
1156 [John K. Sterling <sterling@covalent.net>]
1158 *) Fix merging of AddDefaultCharset directive.
1159 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
1161 *) Minor revamp of the rlimit sections of code. We now test
1162 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
1163 is now "available" even if the platform doesn't support
1164 the rlimit family (it's just a noop though). [Jim Jagielski]
1166 *) Migrate the pre-selection of which MPM to use for specific
1167 platforms to hints.m4, which contains (or should contain)
1168 all platform specific "hints". [Jim Jagielski]
1170 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
1173 *) Add tables with non-string/binary values to APR.
1176 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
1179 *) Update PCRE to version 3.2. [Ryan Bloom]
1181 *) Change the way buckets' destroy functions are called so that
1182 they can be more directly used when changing the type of a
1183 bucket in place. [Tony Finch]
1185 *) Add generic support for reference-counting the resources used by
1186 buckets, and alter the HEAP and MMAP buckets to use it. Change
1187 the way buckets are initialised to support changing the type of
1188 buckets in place, and use it when setting aside TRANSIENT buckets.
1189 Change the implementation of TRANSIENT buckets so that it can be
1190 mostly shared with IMMORTAL buckets, which are now implemented.
1193 Changes with Apache 2.0a6
1195 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
1197 *) Add a chunking filter to Apache. This brings us one step closer
1198 to removing BUFF. [Ryan Bloom]
1200 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
1201 added to the stack is the last filter to be called. [Ryan Bloom]
1203 *) Apache 2.0 has been completely documented using Scandoc. The
1204 docs can be generated by running 'make docs'. [Ryan Bloom]
1206 *) Add filtered I/O to Apache. This is based on bucket brigades,
1207 Currently the buckets still use BUFF under the covers, but that
1208 should change quickly. The only currently written filter is the
1209 core filter which just calls ap_bwrite. [The Apache Group]
1211 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
1212 built with thread support. [Jeff Trawick]
1214 *) Abort configuration if --with-layout was specified and there's
1215 no layout definition file. [Ken Coar]
1217 *) Add support for '--with-port=n' option to configure. [Ken Coar]
1219 *) Add support for extension methods for the Allow response header
1220 field, and an API routine for accessing r->allowed and the
1221 list of extension methods in a unified manner. [Ken Coar]
1223 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
1224 [Rob Simonson <simo@us.ibm.com>]
1226 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
1227 APACHE_XLATE builds. [Jeff Trawick]
1229 *) A configuration file parsing problem was fixed. When the
1230 configuration file started with an IfModule/IfDefine container,
1231 only the last statement in the container would be retained.
1234 Changes with Apache 2.0a5
1236 *) Perchild is serving pages after passing them to different child
1237 processes. There are still a lot of bugs, but this does work. I
1238 have made requests against the same installation of Apache, and had
1239 different servers use different user IDs to serve the responses.
1240 This change moves to using socketpair instead of an AF_UNIX socket.
1243 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
1244 It can't seem to pass between child processes yet, but I think we
1245 are closer now than before. This moves us back to using Unix
1246 Domain Sockets. [Ryan Bloom]
1248 *) libapr functions and types renamed with apr_ prefix.
1249 #include "apr_compat.h" for 1.3.x backwards compat
1252 *) Fix problems with APR sockaddr handling on Win32. It didn't always
1253 return the right information on the local socket address.
1254 [Gregory Nicholls <gnicholls@level8.com>]
1256 *) ap_recv() on Win32: Set bytes-read to 0 on error.
1257 [Gregory Nicholls <gnicholls@level8.com>]
1259 *) Add an option to not detach from the controlling terminal without
1260 going into single process mode. This allows for much easier
1261 debugging of the process startup code. [Ryan Bloom]
1263 *) ab: don't use perror() to report the failure of an APR function.
1266 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
1267 scoreboard on graceful restarts.
1270 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
1271 An invalid ap_proc_t was passed to ap_create_process().
1274 *) Allow modules to register filters. Those filters are still
1275 never called, but this is a step in the right direction.
1276 [Ryan Bloom and Greg Stein]
1278 *) Register the mod_cgid daemon process for cleanup so that it is
1279 killed at termination if it does not die when the parent gets
1280 SIGTERM. This change is to fix occasional problems where the
1281 process stays around. Bugs in similar logic in mod_rewrite and
1282 mod_include were also fixed. [Jeff Trawick]
1284 *) Fix a bug in the time handling. Basically, we were imploding a time
1285 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
1286 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
1287 uses those two fields to adjust the time value. Because of the HTTP
1288 spec, both of those values can be zero'ed out safely. This fixes
1289 the bug correctly. [Ryan Bloom]
1291 *) Fix a couple of place in the Windows code where the wrong error
1292 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
1294 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
1296 *) Added the APR_EOL_STR macro for platform dependent differences in
1297 logfiles and other raw text (such as all APR files). Fixes logfiles
1298 not terminated with cr/lf sequences in Win32. [William Rowe]
1300 *) Move all strings functions in APR to src/lib/apr/strings and create
1301 apr_strings.h for the prototypes. [Ryan Bloom]
1303 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
1304 to repeat the syscall until we stop getting EINTR. I noticed a
1305 related problem at termination (SIGTERM) on FreeBSD when using
1306 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
1307 implementation work properly with child init. Previously, ap_lock()
1308 was essentially a no-op because all children were using different
1309 locks and thus nobody ever blocked. [Jeff Trawick]
1311 *) The htdocs/ tree has been moved out of the CVS source tree into
1312 a separate area for easier development. This has NO EFFECT on
1313 end-users or Apache installations. [Ken Coar]
1315 *) Integrate the mod_dav module for WebDAV protocol handling. This
1316 adds the dav and dav_fs modules, the SDBM library, and additional
1317 XML handling utilities. [Greg Stein]
1319 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
1322 *) Update the lib/expat-lite/ library (bring forward changes from
1323 the Apache 1.3 repository). [Greg Stein]
1325 *) If sizeof(long long) == sizeof(long), then prefer long in APR
1326 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
1328 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
1329 machines where sendfile is detected, but nobody has written ap_sendfile.
1330 [Dave Hill <ddhill@zk3.dec.com>]
1332 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
1334 *) ab would start up more connections than needed, then quit when the
1335 desired number were finished. Also fixed a logic error involving
1336 ab keepalives. [Victor J. Orlikowski]
1338 *) WinNT: Implement non-blocking pipes with timeouts to communicate
1339 with CGIs. Apache 2.0a4 had non-blocking pipes but without
1340 timeouts (i.e, if a timeout was specified, the pipe reverted to
1341 a full blocking pipe). Now the behaviour is more in line with
1342 Unix non-blocking pipes.
1345 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
1346 cache open file handles along with accept socket reuse enables
1347 Apache 2.0 to serve non-keepalive requests for static files at
1348 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
1349 and Apache 2.0 will serve almost 1200 rps on my system).
1352 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
1353 supports two config directives, mmapfile (same behavious as
1354 mod_mmap_static) and cachefile. Use the cachefile directive
1355 to cache open file handles. This directive only works on systems
1356 that have implemented the ap_sendfile API. cachefile works today
1357 on Windows NT, but has not been tested on any flavors of Unix.
1360 *) Cleanup the configuration. With the last few changes the
1361 configuration process automatically:
1362 inherits information about how to build from APR. Allowing
1363 APR to inform Apache that it should or should not use -ldl
1365 Detects which mod_cgi should be used mod_cgi or mod_cgid,
1366 based on the threading model
1368 Apache calls APR's configure process before finishing it's
1369 configuration processing, allowing for more information flow
1374 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
1375 with non-zero argument makes the socket non-blocking. BeOS and
1376 OS/2 already worked this way. [Jeff Trawick]
1378 *) ap_close() now calls ap_flush() for buffered files, so write
1379 operations work a whole lot better on buffered files.
1382 *) Fix error messages issued from MPMs which explain where to change
1383 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
1386 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
1387 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
1388 now the way that the blocking state of a pipe is manipulated.
1389 ap_block_pipe() is gone. [Jeff Trawick]
1391 *) Correct the problem where the only local host name that the IP stack
1392 can discover are 'undotted' private names. If no fully qualified
1393 domain name can be identified, the default ServerName will be set to
1394 the machine's IP address string. A warning is always provided if the
1395 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
1397 *) Repair problems with config file processing which caused segfault
1398 at init when virtual hosts were defined and which caused ServerName to
1399 be ignored when there was no valid DNS setup. [Jeff Trawick]
1401 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
1403 *) Add ap_sendfile implementation for AIX
1404 [Victor J. Orlikowski]
1406 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
1407 apr_network_io.h, and apr_thread_proc.h.
1408 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
1410 *) Bring the allocation and pool debugging code back into a working
1411 state. This will need to be tested as so far it's only been used on
1414 *) Change configuration command setup to be properly typesafe when in
1415 maintainer mode. Note that this requires a compiler that can initialise
1416 unions. [Ben Laurie]
1418 *) Turn on buffering for config file reads. Part of this was to
1419 repair buffered I/O support in Unix and implement buffered
1420 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
1422 *) Win32: Fix problem where UTC offset was not being set correctly
1423 in the access log. Problem reported on news group by Jerry Baker.
1426 *) Fix segfault when reporting this type of syntax error:
1427 "</container> without matching <container> section", where
1428 container is VirtualHost or Directory or whatever.
1431 *) Prevent the source code for CGIs from being revealed when using
1432 mod_vhost_alias and the CGI directory is under the document root
1433 and a user makes a request like http://www.example.com//cgi-bin/cgi
1434 as reported in <news:960999105.344321@ernani.logica.co.uk>
1437 *) Add support for the new Beos NetwOrking Environment (BONE)
1440 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
1441 final input char is incomplete; ap_bwrite_xlate() now handles
1442 incomplete final input chars. [Jeff Trawick]
1444 *) Yet another update to saferead/halfduplex stuff -- need to ensure
1445 that a bhalfduplex call occurs before logging or else DNS and
1446 such can delay the last packet of the response. [Dean Gaudet]
1448 *) Some syscall reduction in APR on unix -- don't seek when setting
1449 up an mmap; and don't fcntl() more than once per socket.
1452 *) When mod_cgid is started as root, the cgi daemon now switches
1453 to the configured User/Group (like other httpd processes)
1454 instead of continuing as root. [Jeff Trawick]
1456 *) The prefork MPM now uses an APR lock for the accept() mutex.
1457 It has not been getting a lock at all recently. httpd -V now
1458 displays APR's selection of the lock mechanism instead of the
1459 symbols previously respected by prefork. [Jeff Trawick]
1461 *) Change the mmap() feature test to check only for existence.
1462 The previous check required features not used by Apache.
1465 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
1466 sometimes mangled. The len parm to accept() was not
1467 initialized, leading sometimes to an endless loop of failed
1468 accept() calls on OS/390 and anywhere else that failed the call
1469 if the len was negative. Use <sys/un.h> for struct sockaddr_un
1470 instead of declaring it ourselves to fix a compilation problem
1471 on Solaris. [Jeff Trawick]
1473 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
1475 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
1477 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
1479 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
1480 initialization if ALLOC_DEBUG is defined; no known symptom
1481 otherwise. [Jeff Trawick]
1483 *) Fix typo in configure script when checking for mod_so. bash
1484 doesn't seem to have a problem but /bin/sh on Solaris does.
1485 Symptom: "./configure: test: unknown operator =="
1488 *) Rebind the Win32 NT and 9x services control into the MPM.
1489 All console, WinNT SCM and Win9x pseudo-service control code is
1490 now wrapped within the WinNT MPM.
1493 *) Make a copy of getenv("PATH") before storing for later use. Some
1494 getenv() implementations use the same storage for successive calls.
1495 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
1497 *) Server Tokens work in 2.0 again. This also propogates the change
1498 to allow just the product name in the server string using
1502 Changes with Apache 2.0a4
1504 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
1505 won't need to call it. [Greg Ames, Jeff Trawick]
1507 *) Move pre_config hook call to between configuration read and config
1508 tree walk. This allows all modules to implement pre_config hooks
1509 and know that they will be called at an appropriate time.
1512 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
1515 *) Add pre-config hooks back to all modules.
1518 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
1519 ContentDigest enabled and we can't/don't mmap the file.
1522 *) We now report the correct line number for syntax errors in config
1523 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
1525 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
1526 related bugs, and changed shmem/locking to use apr API. Shared-mem
1527 is currently disabled, however, because of problems with graceful
1528 restarts. [Ronald Tschalär]
1530 *) Fix corruption of IFS variable in --with-module= handling.
1531 Depending on the user's shell or customization thereof, there
1532 would be errors generating ap_config_auto.h later in the configure
1533 procedure. [Jeff Trawick]
1535 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
1536 isn't used (as in 1.3), except that on Unix it is now logged via
1537 ap_log_rerror() instead of by the child having STDERR_FILENO refer
1538 to the error log. [Greg Ames, Jeff Trawick]
1540 *) Add '-D' argument processing for run time configuration defines.
1543 *) Organize http_main.c as independent code, such that no code or
1544 global data is exported from it. WIN32 will dynamically link it
1545 to the server core, so this will prevent mutual dependency.
1548 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
1549 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
1552 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
1553 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
1555 *) Add mod_charset_lite for configuring character set translation.
1558 *) Add '-n' option to htpasswd to make it print its user:pw record
1559 on stdout rather than having to frob a text file. [Ken Coar]
1561 *) Fix saferead. Basically, we flush the output buffer if a read on the
1565 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
1566 a conversion is single-byte only. [Jeff Trawick]
1568 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
1569 the BeOS 5.0 documentation says that shutdown doesn't work yet.
1572 *) Fix some minor errors where pid was being manipulated as an int
1573 instead of the portable pid_t. [Roy Fielding]
1575 *) Fix some error log prints that were printing the pointer to a
1576 structure rather than the pid within the structure.
1577 [Jeff Trawick, Roy Fielding]
1579 *) ab: Fix a command-line processing bug; track bad headers in
1580 err_response; support reading headers up to 2K.
1581 [Ask Bjoern Hansen <ask@valueclick.com>]
1583 *) Fix ap_resolve_env() so that it handles new function added in a prior
1584 alpha (see "Added the capability to do ${ENVVAR} constructs in the
1585 config file.") as well as the constructs used by mod_rewrite.
1586 [Paul Reder <rederpj@raleigh.ibm.com>]
1588 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
1590 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
1591 APR to perform translation, instead of accessing the hard-coded tables
1592 in 1.3's ebcdic.c. [Jeff Trawick]
1594 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
1597 *) Add the ability to hook into the config file reading phase. Basically
1598 if a directive is specified EXEC_ON_READ, then when that directive is
1599 read from the config file, the assocaited function is executed. This
1600 should only be used for those directives that must muck with HOW the
1601 server INTERPRETS the config. This should not be used for directives
1602 that re-order or replace items in the config tree. Those changes should
1603 be made in the pre-config step.
1606 *) Add mod_example to the build system.
1609 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
1610 byte character sets. [Jeff Trawick]
1612 *) Pick up various EBCDIC fixes from 1.3 (from Martin
1613 Kraemer and Oliver Reh originally according to the change log).
1616 *) Fix a couple of problems in RFC1413 support (controlled by the
1617 IdentityCheck directive). Apache did not build the request string
1618 properly and more importantly Apache would loop forever if the
1619 would-be ident server dropped the connection before sending a
1620 properly terminated response. [Jeff Trawick]
1622 *) apxs works in 2.0.
1625 *) Reliable piped logs work in 2.0.
1628 *) Introduce a hash table implementation into APR to be used for
1629 replacing tables and other random data structures in Apache.
1632 *) Add some more error reporting to htpasswd in the case of problems
1633 generating or accessing the temporary file. Also, pass in a
1634 buffer if the implementation knows how to use it (i.e., if L_tmpnam
1635 is defined). [Ken Coar]
1637 *) Configure creates config.nice now containing your configure
1638 options. Syntax: ./config.nice [--more-options]
1641 *) Fix various return code problems in APR on Win32. For most of
1642 these, APR was returning APR_EEXIST instead of GetLastError()/
1643 WSAGetLastError(). [Jeff Trawick]
1645 *) Make piped logs work again in version 2.0
1648 *) Add VPATH support to UNIX build system of Apache and APR.
1651 *) Fix ap_tokenize_to_argv to respect the const arguments that are
1655 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
1656 Patch submitted to author.
1659 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
1660 /sbin in PATH on FreeBSD (all submitted to rse previously)
1663 *) Fix building Pthread-based MPMs on OpenBSD
1664 [Sascha Schumann] PR#26
1666 *) Fix ap_readdir() problem on systems where d_name[] field in
1667 struct dirent is declared with only one byte. (This problem only
1668 affected multithreaded builds.) This caused a segfault during
1669 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
1670 least). [Jeff Trawick]
1672 *) Fix some make-portability problems on at least Tru64, Irix
1674 [Sascha Schumann] PR#18, PR#39
1676 *) Add ap_sigwait() to support old-style sigwait() on systems
1677 like OS/390 and UnixWare.
1680 *) Add POSIX-thread flags for more platforms.
1683 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
1684 (on Unix, at least) to handle resolver errors. Fix a bug in
1685 the definition of APR_ENOMEM so that ap_strerror() can spit
1686 out the correct error message for it.
1689 Changes with Apache 2.0a3
1691 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
1694 *) API: *HOOK* macros now have an AP_ prefix
1697 *) Win32: Eliminate redundant calls to initialize winsock.
1698 [Tim Costello <timcostello@ozemail.com.au>]
1700 *) Fix bugs initializing ungetchar for pipes.
1701 [Chia-liang Kao <clkao@CirX.ORG>]
1703 *) The ab program in the src/support directory is now portable using
1707 *) Support directory is being compiled when the server is built
1710 *) The configure option --with-program-name has been added to allow
1711 developers to rename the executable at configure time. This also
1712 changes the name of the config files to match the executable's name.
1715 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
1716 containing version numbers. [Martin Pool]
1718 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
1719 Unix; access_log and error_log now created with these perms; non-
1720 Unix is unaffected [Jeff Trawick]
1722 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
1723 Replaced more magic numbers with MD5_DIGESTSIZE.
1724 [William Rowe, Roy Fielding]
1726 *) Win32: Get mod_auth_digest compiling and added to the Windows
1727 build environment. Not tested and I'd be suprised if it
1728 actually works. [Bill Stoddard]
1730 *) Revamp the Win32 make environment. Makefiles have been removed and
1731 Apache.dsw created to bring together all the pieces. Create new file
1732 os/win32/BaseAddr.ref to define module base addresses (to prevent
1733 dll relocation at start-up).
1734 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
1736 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
1737 of the \015, \012, and \015\012 constants with macros.
1738 [Greg Ames <gregames@us.ibm.com>]
1740 *) Add ap_xlate_open() et al for translation of text between different
1741 character sets. The initial implementation requires iconv().
1744 *) More FAQs and answers from comp.infosystems.www.servers.unix.
1745 [Joshua Slive <slive@finance.commerce.ubc.ca>]
1747 *) CGI output is being timed out now.
1750 *) Fix the problem with dieing quietly. dupfile now takes a pool which
1751 is used by the new apr file. There is no reason to create a new file
1752 with the same lifetime as the original file.
1755 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
1756 module base addresses. This will help shooting seg faults
1757 in the field. [William Rowe <wrowe@lnd.com>]
1759 *) Update Apache on Windows documentation. Add new document
1760 describing how to compile Apache on Windows.
1761 [William Rowe <wrowe@lnd.com>]
1763 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
1764 microseconds instead of seconds. Some storage leaks and other
1765 minor bugs in related code were fixed. [Jeff Trawick]
1767 *) Win32: First cut at getting mod_isapi working under 2.0
1768 [William Rowe <wrowe@lnd.com>]
1770 *) First stab at getting mod_auth_digest working under 2.0
1771 quick change summary:
1772 - moved the random byte generation (ap_generate_random_bytes) into APR
1773 - now uses ap_time_t
1774 - compiles and runs on linux
1776 [Brian Martin <bmartin@penguincomputing.com>]
1778 *) Win32: Move the space stripping of physical service names
1779 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
1780 unresolved symbol. Add dependency checking to the
1781 CreateService call to ensure TCPIP and AFP (winsock) is started
1783 [William Rowe <wrowe@lnd.com>]
1785 *) Win32: Add code to perform latebinding on functions that may
1786 not exist on all levels of Windows where Apache runs. This
1787 is needed to allow Apache to start-up on Win95/98. All calls
1788 to non portable functions should be protected with
1789 ap_oslevel checks to prevent runtime segfaults.
1790 [William Rowe <wrowe@lnd.com>]
1792 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
1794 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
1796 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
1797 This addresses PR 1623. Still need to address timing out runaway
1798 CGI scripts. [Bill Stoddard]
1800 *) Win32: Make ap_stat Windows 95/98 friendly
1801 [William Rowe <wrowe@lnd.com>]
1803 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
1804 always fail. Need to initialise the dwOSVersionInfoSize member of the
1805 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
1808 The patch also enhances ap_get_oslevel (and the associated enum) to
1809 handle selected service packs for NT4, and adds recognition for
1810 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
1811 we can use ReadFileScatter and WriteFileGather in readwrite.c.
1812 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
1814 *) Get mod_rewrite building and running, and mod_status building for Win NT
1815 [Allan Edwards <ake@raleigh.ibm.com>]
1817 *) Patch to port mod_auth_db to the 2.0 api and also to support
1818 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
1819 2.7.7. It should work with version 1 as well but I haven't tested it.
1820 [Brian Martin <bmartin@penguincomputing.com>]
1822 *) Get APR DSO code working under Windows. Includes cross platform
1824 [Tim.Costello@BTFinancialgroup.com]
1826 *) Fix some of the Windows APR time functions.
1829 *) FAQ changes related to tidying up historical documents on the web site.
1830 [Joshua Slive <slive@finance.commerce.ubc.ca>]
1832 *) Move Windows DSO code into APR.
1835 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
1836 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
1837 at build time. At this point, the server will not compile on Windows because
1838 of the recent DSO commits. Fixing those next.
1839 [Bill Rowe & Bill Stoddard]
1841 *) Added error checking for file I/O APR routines.
1842 [Jon Travis <jtravis@covalent.net>]
1844 *) APR: Don't use the values of resolver error codes for the
1845 corresponding APR error codes. On Unix and Win32, return the
1846 proper APR error code after a resolver error. [Jeff Trawick]
1848 Changes with Apache 2.0a2
1850 *) Renamed the executable back to httpd on all platforms other
1854 *) Allow BeOS to survive restarts, log properly and a few
1855 small things it had problems with due to the way it setup
1856 users and groups. [David Reid]
1858 *) Get mod_rewrite working with APR locks
1859 [Paul Reder <rederpj@raleigh.ibm.com>]
1861 *) Actually remove the sempahore when the lock cleanup routine
1862 is called on BeOS. [David Reid]
1864 *) Clear hook registrations between reads of the config file.
1865 When DSOs are unloaded and re-loaded the old hook pointers may
1866 no longer be valid. This fix eliminates potential segfaults.
1867 [Allan Edwards <ake@raleigh.ibm.com>]
1869 *) Fix a problem with Sigfunc not being defined or bypassed
1870 if sigaction() wasn't found. [Jim Jagielski]
1872 *) Fix the locking mechanism on BSD variants. They now use fcntl
1873 locks. This allows the server to start and serve pages.
1876 *) First cut at getting the Win32 installer to work
1877 [William Rowe <wrowe@lnd.com>]
1879 *) Get htpasswd compiling under Windows
1880 [William Rowe <wrowe@lnd.com>]
1882 *) Change the log message for a bind() failure to show the
1883 interface and port number. [Jeff Trawick]
1885 *) Import the documentation from 1.3.12 and bring parts of it
1886 up-to-date with respect to the changes that have occurred
1890 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
1891 now logged correctly on BeOS.
1894 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
1895 Makefile.win includes the same user interface as the old
1897 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
1899 *) Win32 exec now uses COMSPEC environment string for command
1900 shell path resolution.
1901 [William Rowe <wrowe@lnd.com>] PR#3715
1903 *) Win32: ap_connect() was not returning correct error condition
1905 [Allen Prescott <allen@clanprescott.com>]
1907 *) Win32: ap_open() was broken on Win9x because an NT-specific
1908 flag was passed to CreateFile. ap_puts() added an unnecessary
1910 [Jeff Trawick <trawick@us.ibm.com>]
1912 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
1913 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
1914 confusing ee/et name and made all extensions language/dialect
1915 rather than country reflecting. Changed example files to
1916 explicit reflect the ISO charset and added a few common
1917 ones to the example config [dirkx]
1919 *) Extend external module capability. To use this, you call
1920 configure with --with-module=path/to/mod1,path/to/mod2,etc.
1923 *) Backported the various "default charset" fixes from 1.3.12,
1924 including the AddDefaultCharset directive. [Jim Jagielski]
1926 *) Added the capability to do ${ENVVAR} constructs in the
1927 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
1928 it does this on a line by line basis; i.e. if the envvar
1929 expands to something with spaces you have to protect it
1930 by adding quotes around it (Unless of course you expect it
1931 to contains more than one argument. Alternatively you
1932 can compile it on a per token basis; which is what people
1933 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
1934 hampers fancier hacks.
1935 [Dirk-Willem van Gulik]
1937 *) Changed the 'ErrorDocument' syntax in that it NO longer
1938 supports the asymetric
1940 ErrorDocument 301 "Some message
1942 Note the opening " quote, without a closing quote. It now
1943 has either the following syntaxes
1945 ErrorDocument XXX /local/uri
1946 ErrorDocument XXX http://valid/url
1947 ErrorDocument XXX "Some Message"
1949 The recognition heuristic is: if it has a space it
1950 is a message. If it has no spaces and starts with a /
1951 or is a valid URL then treat it that way. Otherwise it
1952 is assumed to be a message.
1954 This breaks backward compatibility but makes live a hell
1955 of a lot easier for GUI's and config file parsers.
1956 [Dirk-Willem van Gulik]
1958 *) Changed 'CacheNegotiatedDocs' from its present/not-present
1959 syntax into a 'on' or 'off' syntax. As it currently is the
1960 only non nesting token which uses NO_ARGS and thus is an
1961 absolute pain for any config interface automation. This
1962 breaks backward compatibility. [Dirk-Willem van Gulik]
1964 *) Add ability to add external modules to the build process. This is
1965 done with --with-module=/path/to/module. Modules can only be added
1966 as static modules at this point.
1969 Changes with Apache 2.0a1
1971 *) Fix FreeBSD 3.3 core dump.
1972 Basically, ap_initialize() needs to get called before
1973 create_process(), since create_process() passes op_on structure
1974 to semop() to get a lock, but op_on isn't initialized until
1975 ap_initialize() calls setup_lock(). Here is a slight
1976 rearrangement to main() which calls ap_initialize() earlier...
1977 [Jeff Trawick <trawick@us.ibm.com>]
1979 *) Enable Apache to use sendfile/TransmitFile API
1980 [Bill Stoddard, David Reid, Paul Reder]
1982 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
1986 *) Make file I/O and network I/O writev/sendv APIs consistent.
1987 Eliminate use of ap_iovec_t and use Posix struct iovec.
1988 Use seperate variable on ap_writev to set the number of iovecs
1989 passed in and number of bytes written.
1992 *) Adapt file iol to use APR functions. Replaced ap_open_file()
1993 with ap_create_file_iol(). ap_create_file_iol() requires that
1994 the file be opened prior to the call using ap_open().
1997 *) Port mod_include and mod_cgi to 2.0
1998 [Paul Reder, Bill Stoddard]
2000 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
2001 bytes_read/bytes_written is always valid (never -1). Plus
2002 some fixes to buff.c to correct problems introduced by the
2003 errno => ap_status_t changes a while back. Plus a fix to
2004 chunked encoding introduced right at the beginning of 2.0.
2007 *) Revamped UNIX build system to use autoconf and libtool.
2008 [Manoj Kasichainula, Sascha Schumann]
2010 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
2012 *) More rigorous checking of Host: headers to fix security problems
2013 with mass name-based virtual hosting (whether using mod_rewrite
2014 or mod_vhost_alias).
2015 [Ben Hyde, Tony Finch]
2017 *) Add back support for UseCanonicalName in <Directory> containers.
2018 [Manoj Kasichainula]
2020 *) Added APLOG_STARTUP log type. This allows us to write an error
2021 message without any of the date and time information. As a part
2022 of this change, I also removed all of the calls to fprintf(stderr
2023 and replaced them with calls to ap_log_error using APLOG_STARTUP
2024 writing to stderr is no longer portable, because we don't direct
2025 stderr to the error log on all platforms.
2028 *) Convert error logging functions to take errno as an argument.
2029 This makes our error logs more portable, because some Windows API's
2030 don't set errno. This change allows us to still output a valid
2031 message on all of our platforms.
2034 *) mod_mime_magic runs in 2.0-dev now.
2035 [Paul Reder <rederpj@raleigh.ibm.com>]
2037 *) sendfile has been added to APR.
2038 [John Zedlewski <zedlwski@Princeton.EDU>]
2040 *) buff.c has been converted to no longer use errno.
2041 [Manoj Kasichainula]
2043 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
2044 interface adaption to APR functions did it. [Martin Kraemer]
2046 *) Support DSOs properly on 32-bit HP-UX 11.0
2047 [Dilip Khandekar <dilip@cup.hp.com>]
2049 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
2050 [Ralf S. Engelschall]
2052 *) Cleaned APR build environment integration and bootstrap APR
2053 automatically for developers from src/Configure.
2054 [Ralf S. Engelschall]
2056 *) Fixed building of src/support/htpasswd.c
2057 [Ralf S. Engelschall]
2059 *) When generating the Location: header, mod_speling forgot
2060 to escape the spelling-fixed uri. (Forw-Port from 1.3)
2063 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
2065 *) Change all pools to APR contexts. This is the first step to
2066 incorporating APR into Apache. [Ryan Bloom]
2068 *) Move "handler not found" warning message to below the check
2069 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
2070 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
2072 *) Support line-continuation feature in config.option file and
2073 allow the loading of multiple option sections at once via
2074 ``--with-option=<section1>,<section2>,...''
2075 [Ralf S. Engelschall]
2077 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
2079 Changes with Apache MPM
2081 *) Use asynchronous AcceptEx() and a completion port to accept and
2082 dispatch connections to threads in Windows NT/2000.
2085 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
2088 *) Implement the APACI --with-option facility
2089 (per default used the config.option file).
2090 [Ralf S. Engelschall]
2092 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
2094 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
2095 Replace pre_connection module call with a register_hook call and
2096 implement pre_connection as a hook. The intent is that these hooks will
2097 be extended to allow Apache to be multi-protocol, and also to allow the
2098 calling order to be specified on a per-hook/per-module basis.
2101 *) Implement mpm_* methods as "modules". Each method gets its own
2102 subdir in src/modules (eg: src/modules/prefork). Selection
2103 of method uses Rule MPM_METHOD. [Jim Jagielski]
2105 *) Port the hybrid server from the apache-apr repository as
2106 mpm_mpmt_pthread. [Manoj Kasichainula]
2108 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
2109 amongst the unix MPMs.
2111 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
2112 signal handling for the new world order. [Dean Gaudet]
2114 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
2115 of alloc.c for now. [Dean Gaudet]
2117 *) Handle partial large writes correctly. [Ben Laurie]
2119 *) Eliminate conn_rec's pointer to server. All it knows is the base server
2120 based on IP/port. [Ben Laurie]
2122 *) Port a bunch of modules to the new module structure.
2123 ["Michael H. Voase" <mvoase@midcoast.com.au>]
2125 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
2127 *) Basic restructuring to introduce the MPM concept; includes various
2128 changes to the module API... better described by
2129 docs/initial_blurb.txt. [Dean Gaudet]
2131 Changes with Apache pthreads
2133 *) New buff option added: BO_TIMEOUT. It describes the timeout for
2134 buff operations (generally over a network).
2135 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
2137 *) Created http_accept abstraction. Added 4 new functions (not exported):
2138 init_accept(), begin_accepting_requests(), get_request(),
2139 stop_accepting_requests() [Bill Stoddard]
2141 *) Fix to ap_rprintf call that allows mod_info to work properly.
2142 [James Morris <jmorris@intercode.com.au>]
2144 *) user and ap_auth_type fields were moved from connection_rec to
2145 request_rec. [Ryan Bloom]
2147 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
2148 needed in a threaded server.
2150 *) Initial pthread implementation from from Dean's apache-nspr code.
2151 [Bill Stoddard, Ryan Bloom]
2154 Changes with Apache 1.3.9
2156 *) Remove bogus error message when a redirect doesn't set Location.
2157 Instead, use an empty string to avoid coredump if the error message
2158 was supposed to include a location. [Roy Fielding]
2160 *) Don't allow configure to include mod_auth_digest unless it is
2161 explicitly requested, even if the user asked for all modules.
2164 *) Translate module names to dll names for OS/2 so that they are no more
2165 than 8 characters long and have an extension of "dll" instead of "so".
2168 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
2169 Fix test-compile check to check for randbyte instead of trand32.
2170 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
2171 and tweak to make Amaya happier. [Ronald Tschalär]
2173 *) Ensure that the installed expat include files are world readable,
2174 just like the other header files. [Martin Kraemer]
2176 *) Fixed generated AddModule adjustments in APACI's `configure' script
2177 in order to allow (new) modules like mod_vhost_alias to be handled
2178 correctly (which was touched by the adjustments for mod_alias).
2179 [Ralf S. Engelschall]
2181 *) For binary builds, add -R flag to apachectl to work around the lack of
2182 an absolute path to the ./libexec directory where the libhttp.ep file
2183 is needed for SHARED_CORE architectures. [Randy Terbush]
2185 *) WIN32: Create the CGI script process as DETACHED. This may solve the
2186 problem observed by some Win95/98 users where they get CGI script
2187 output sent to the console. [Bill Stoddard]
2189 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
2190 routines are now called ap_base64* and are 'plain' (i.e., no
2191 pool access or anything clever). Inside util.c the routines acting
2192 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
2193 The oddly named ap_uuencode(), ap_uudecode() are kept around for
2194 now but deprecated. [dirkx]
2196 *) Clean up the base64 and SHA1 additions and make sure they are
2197 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
2198 files. [Roy Fielding]
2200 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
2201 checking. Allow compiling on VS 6.0. [Randy Terbush]
2203 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
2205 *) Use TestCompile to search for the truerand library (rather than blindly
2206 assuming its existence). If it is not found, complain (but do not
2207 exit - yet). [Martin Kraemer]
2209 *) We forgot to add the new exported function names to
2210 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
2212 *) Add description of -T command-line option to usage().
2213 [Ralf S. Engelschall]
2215 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
2216 searched only AFTER libap has been searched, because libap needs
2217 some symbols from libos. [Martin Kraemer]
2219 *) Fix conflict with original mod_digest related to the symbol of the
2220 module dispatch list (which has to be unique for DSO and follow the
2221 usual conventions for the installation procedure).
2222 [Ralf S. Engelschall]
2224 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
2225 for other platforms as well. [Martin Kraemer]
2227 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
2228 types by AP_LONG and replace reference to renamed variable 'ubuf'
2229 by 'buffer'. [Martin Kraemer]
2231 Changes with Apache 1.3.8 [not released]
2233 *) Flush the output buffer immediately after sending an error or redirect
2234 response, since the result may be needed by the client to abort a
2235 long data transfer or restart a series of pipelined requests.
2236 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
2238 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
2239 [Ian Turner <iant@sequent.com>] PR#4735
2241 *) Local struct mmap in http_core.c conflicted with system structure
2242 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
2244 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
2245 [Ronald Tschalär <ronald@innovation.ch>]
2247 *) Fix a memory leak where the module counts were getting messed
2248 up across restarts. [David Harris <dharris@drh.net>]
2250 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
2251 properly in mod_access.
2252 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
2254 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
2255 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
2257 *) PORT: Support for compaq/tandem/com.
2258 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
2260 *) Added SHA1 password encryption support to easy migration from
2261 Netscape servers. See support/SHA1 for more information.
2262 Caused the separation of ap_md5.c into md5, sha1 and a general
2263 ap_checkpass.c with just a validate_passwd routine. Added a
2264 couple of flags to support/htpasswd. Some reuse of the to64()
2265 function; hence renamed to ap_to64().
2266 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
2268 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
2269 with ASCII/EBCDIC conversions in "ident" query.
2270 [David McCreedy <McCreedy@us.ibm.com>]
2272 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
2273 Change "Power Macintosh" to Power* so if uname prints "Power Book"
2274 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
2276 *) Fix SIGSEGV on some systems because the Vary fix below included
2277 a call to table_do with a variable argument list that was not
2278 NULL terminated. Replaced with better implementation. [Roy Fielding]
2280 Changes with Apache 1.3.7 [not released]
2282 *) The "Vary" response header field is now sanitised right before
2283 the header is sent back to the client. Multiple "Vary" fields
2284 are combined, and duplicate tokens (e.g., "Vary: host, host" or
2285 "Vary: host, negotiate, host, accept-language") are reduced to
2286 single instances. This is a better solution than the force-no-vary
2287 one (which is still valid for clients that can't cope with Vary
2288 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
2290 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
2292 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
2293 least on Linux and FreeBSD for now.
2296 *) Win32: More apache -k restart work. Restarts are now honored
2297 immediately and connections in the listen queue are -not- lost.
2298 This is made possible by the use of the WSADuplicateSocket()
2299 call. The listeners are opened in the parent, duplicated, then
2300 the duplicates are passed to the child. The original listen sockets
2301 are not closed by the parent across a restart, thus the listen queue
2303 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2305 *) Fix handling of case when a client has sent "Expect: 100-continue"
2306 and we are going to respond with an error, but get stuck waiting to
2307 discard the body in the pointless hope of preserving the connection.
2308 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
2310 *) Fix 'configure' to work correctly with SysV-based versions of
2311 'tr' (consistent with Configure's use as well). [Jim Jagielski]
2313 *) apxs: Add "-S var=val" option which allows for override of CFG_*
2314 built-in values. Add "-e" option which works like -i but doesn't
2315 install the DSO; useful for editing httpd.conf with apxs. Fix
2316 editing code so that multiple invocations of apxs -a will not
2317 create duplicate LoadModule/AddModule entries; apxs can now be
2318 used to re- enable/disable a module. [Wilfredo Sanchez]
2320 *) Win32: Update the server to use Winsock 2. Specifically, link with
2321 ws2_32.lib rather than wsock32.lib. This gives us access to
2322 WSADuplcateSocket() in addition to some other enhanced comm APIs.
2323 Win 95 users may need to update their TCP/IP stack to pick up
2324 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
2325 [Bill Stoddard stoddard@raleigh.ibm.com]
2327 *) Win32: Redirect CGI script stderr (script debug info) into the
2328 error.log when CGI scripts fail. This makes Apache on Win32
2329 behave more like Unix.
2330 [Bill Stoddard stoddard@raleigh.ibm.com]
2332 *) Fixed `httpd' usage display: -D was missing.
2333 [Ralf S. Engelschall] PR#4614
2335 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
2336 [Ralf S. Engelschall] PR#4561, PR#4562
2338 *) OS/2: Fix problem with accept lock semaphores where server would die with
2339 "OS2SEM: Error 105 getting accept lock. Exiting!"
2340 [Brian Havard] PR#4505
2342 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
2343 [Randy Terbush <randy@covalent.net>]
2345 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
2346 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
2348 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
2349 command potentially _is_ GCC. [Ralf S. Engelschall]
2351 *) Fix apxs build issues on AIX
2352 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
2354 *) DocumentRoot Checking: Under previous versions, when Apache
2355 first started up, it used to do a stat of each DocumentRoot to
2356 see if it existed and was a directory. If not, then an error

2365 *) Win32: The query switch "apache -S" didn't exit after showing the
2366 vhost settings. That was inconsistent with the other query functions.
2367 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
2369 *) Win32: Changed behaviour of apache -k restart.
2370 Previously, the server would drain all connections in the stack's
2371 listen queue before honoring the restart. On a busy server, this
2372 could take hours. Now, a restart is honored almost immediately.
2373 All connections in Apache's queues are handled but connections in
2374 the stack's listen queue are discarded. Restart triggered by
2375 MaxRequestPerChild is unchanged.

2409 *) The source is now quad (long long) aware as needed. Specifically,
2410 the Configure process determines the correct size of off_t and
2411 *void. When the OS/platform/compiler supports quads, ap_snprintf()
2412 provides for the 'q' format qualifier (if quads are not available,
2413 'q' is silently "demoted" to long). [Jim Jagielski]
2415 *) When the username or password fed to htpasswd is too long, include the

2519 install-bindist.sh now detects the local perl5 path to install
2520 apxs and dbmmanage with proper path to perl interpreter.
2522 Add an install-binsupport target which copies the source files

2694 *) proxy ftp: instead of using the hardwired string "text/plain" as
2695 a fallback type for files served by the ftp proxy, use the

2697 This allows for special configurations like
2698 <Directory proxy:ftp://some.host>
2699 DefaultType gargle/blurb
2701 Additionally, add the Content-Encoding: header to FTP proxy replies
2702 when the encoding is defined (by the AddEncoding directive).
2703 Because it was missing, it was almost impossible to browse compressed
2704 files using the FTP proxy (works now perfectly in Communicator).
2705 The ftp proxy now also returns the Date: and Server: header lines (if not
2706 much else... This code is "somewhat" broken) like normal requests do.

2830 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
2831 correctly check for output errors and mark the connection as aborted.
2832 Replaced many direct (unchecked) calls to ap_b* routines with the

2837 Furthermore map lookups for non-existent keys are now cached as well.
2838 Additionally "txt" maps are now parsed with simple string functions
2839 instead of using ap_pregcomp(). As a side effect a bug that prevented

2878 David N. Welton: you can now have it generate an HTML TABLE, presumably
2879 for integration into other HTML sources. David updated the ab man page
2880 as well and added some missing descriptions. Thanks!
2881 [David N. Welton <davidw@prosa.it>]
2883 *) Win32: The filename validity checker now allows filenames containing
2884 characters in the range 0x80 to 0xff (for example accented characters).
2885 [Paul Sutton] PR#3890
2887 *) Added conditional logging based upon environment variables to
2888 mod_log_config. mod_log_referer and mod_log_agent
2889 are now deprecated. [Ken Coar]
2891 *) Allow apache acting as a proxy server to relay the real
2892 reason of a failure to a client rather than the "internal
2893 server error" it does currently. The general exposure mechanism
2894 can be triggered by any module by setting the "verbose-error-to"
2895 note to "*"; this allows more than just proxy errors to be exposed.
2896 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
2898 *) Moved man pages for ab and apachectrl to section 8.
2899 [Wilfredo Sanchez, Roy Fielding]
2901 *) Added -S option to install.sh so that options can be passed to
2902 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
2904 *) Tweak modules Makefile generated by Configure so that it handles
2905 the test case of no modules being selected. [chaz@reliant.com]
2907 *) Added a <LimitExcept method ...> sectioning directive that allows
2908 the user to assign authentication control to any HTTP method that
2909 is *not* given in the argument list; i.e., the logical negation
2910 of the <Limit> directive. This is particularly useful for controlling
2911 access on methods unknown to the Apache core, but perhaps known by
2912 some module or CGI script. [Roy Fielding, Tony Finch]
2914 *) Prevent apachectl from complaining if the PIDFILE exists but
2915 does not contain a process id, as might occur if the server is
2916 being rapidly restarted. [Wilfredo Sanchez]
2918 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
2920 *) Entity tag comparisons for If-Match and If-None-Match were not being
2921 performed correctly -- weak tags might cause false positives. Also,
2922 strong comparison wasn't properly enforced in all cases.
2923 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
2925 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
2928 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
2929 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
2931 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
2932 to util.c for parsing an HTTP header field value to extract the next
2933 list item, taking into account the possible presence of nested comments,
2934 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
2935 insignificant whitespace and lowercases non-quoted tokens.
2936 [Roy Fielding] PR#2065
2938 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
2939 code different from 500. This allows the proxy to, e.g., return
2940 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
2942 *) Fix ordering of language variants for the case where the traditional
2943 negotiation algorithm is being used with multiple language variants
2944 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
2946 *) Do not round the TCN quality calculation to 5 decimal places,
2947 unlike RFC 2296, because the calculation might need 12 decimal places
2948 to get the right result. [Roy Fielding]
2950 *) Remove unused code to disable transparent negotiation when
2951 negotiating on encoding only, as we now handle encoding too
2952 (though this is nonstandard for TCN), remove charset=ISO-8859-1
2953 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
2954 some debugging statements within mod_negotiation. [Koen Holtman]
2956 *) Fixed a rare memory corruption possibility in mod_dir if the index
2957 file is negotiable and no acceptable variant can be found.
2958 [Dean Gaudet, Roy Fielding, Martin Kraemer]
2960 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
2961 searching the Win32 registry for script interpreters.
2964 *) Win32: The compiled-in default filename for the error log is now
2965 error.log, which matches the default in the distributed httpd.conf.
2968 *) Win32: Any error messages from -i or -u command line options are now
2969 displayed on the console output rather than sent to the error log.
2970 Also the "Running Apache..." message is not output unless Apache is
2971 going to serve requests. [Paul Sutton]
2973 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
2974 and use a private significator ('$apr1$') to mark passwords as
2975 being smashed with our own algorithm. Also abstract the password
2976 checking into a new ap_validate_password() routine. [Ken Coar]
2978 *) Win32: The filename validity checker now allows "COM" but refuses
2979 access to "COM1" through "COM4". This allows filenames such
2980 as "com.name" to be served. [Paul Sutton] PR#3769.
2982 *) BS2000: Adapt to the new ufork() system call interface which will
2983 make subtasking easier on the OSD/POSIX mainframe environment.
2986 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
2987 ap_compat.h. [David White <david@persimmon.com>] PR#3725
2989 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
2990 use `.db' instead of `.pag' not only for FreeBSD, but also when
2991 the NDBM library looks like Berkeley-DB based.
2992 [Ralf S. Engelschall] PR#3773
2994 *) Add ability to handle DES or MD5 authentication passwords.
2995 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
2997 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
2999 *) SECURITY: Avoid some buffer overflow problems when escaping
3000 quoted strings. (This overflow was on the heap and we believe
3001 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
3003 *) Let src/Configure be aware of CFLAGS options starting with plus
3004 signs as it's the case for the HP/UX compiler.
3005 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
3007 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
3008 and check to see if the tar we wind up with supports '-h'.
3009 [Jim Jagielski] PR#3671
3011 *) A consistent and conservative style for all shell scripts has been
3012 implemented. Basically, all shell string tests use the traditional
3013 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
3014 to protect against bare null variable strings (ie: wrapping both
3015 sides with double quotes and prepending 'x'). 'x' was chosen
3016 because it's more universal and hopefully easier for old shell
3017 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
3020 *) The status module now prints out both the main server generation as
3021 well as the generation of each process. Also, the vhost info is
3022 printed with '?notable'. [Jim Jagielski]
3024 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
3025 and this makes its functions available to things in src/support.
3028 Changes with Apache 1.3.4
3030 *) Renamed macros status_drops_connection to ap_status_drops_connection
3031 and vestigial scan_script_header to ap_scan_script_header_err,
3032 mostly for aesthetic reasons. [Roy Fielding]
3034 *) The query switch "httpd -S" didn't exit after showing the
3035 vhost settings. That was inconsistent with the other query functions.
3038 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
3039 filename to the end of the STANDARD_MODULE_STUFF. Its
3040 presence at the beginning prevented reporting of the filename
3041 for modules compiled before 1 January 1999. [Ken Coar]
3043 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
3044 to detect and prevent access to special DOS device file names.
3045 [Paul Sutton, Ken Parzygnat]
3047 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
3048 and Makefile_win32_debug.txt (debug build) that work on Win95.
3049 Run each of the following from the src directory:
3050 nmake /f Makefile_win32.txt # compiles normal build
3051 nmake /f Makefile_win32.txt install # compiles and installs
3052 nmake /f Makefile_win32.txt clean # removes compiled junk
3053 nmake /f Makefile_win32_debug.txt # compiles debug build
3054 nmake /f Makefile_win32_debug.txt install
3055 nmake /f Makefile_win32_debug.txt clean
3058 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
3059 to build binary distributions. [Lars Eilebrecht]
3061 *) IndexOptions SuppressColumnSorting only turned off making
3062 the column headers anchors; you could still change the display
3063 order by manually adding a '?N=A' or similar query string to the
3064 URL. Now SuppressColumnSorting locks in the sort order so
3065 it can't be overridden this way. [Ken Coar]
3067 *) Added IndexOrderDefault directive to supply a default sort order
3068 for FancyIndexed directory listings. [Ken Coar] PR#1699
3070 *) Change the ap_assert macro to a variant that works on all platforms.
3071 [Richard Prinz <richard.prinz@cso.net>] PR#2575
3073 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
3074 search for an underscore on dlsym() (as it's already the case
3075 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
3077 *) Small fix for mod_env.html: The module was documented as to be _not_
3078 compiled into Apache per default, although it _IS_ compiled into
3079 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
3081 *) Instead of fixing a bug in the generation procedure for config.status (a
3082 backslash was missing) we remove the bug together with it's complete
3083 context because the special cases of the past can now no longer occur
3084 because of the recent magic for the --with-layout default.
3085 [Ralf S. Engelschall] PR#3590
3087 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
3088 making sure the src/support/ tools are _forced_ to be build last (they
3089 depend on other libraries).
3090 [Markus Theissinger <markus.theissinger@gmx.de>]
3092 *) Fix installation procedure: Now that os-inline.c is actually used (a
3093 recently fixed bug prevented this) we need to also install os-include.c
3094 in addition to os.h into the PREFIX/include/ location or building of
3095 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
3097 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
3098 allow us to distinguish between a garbled DSO (or even a file which isn't
3099 an Apache module DSO at all) and a DSO which doesn't match the current
3100 Apache API. [Ralf S. Engelschall] PR#3152
3102 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
3103 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
3104 match case insensitive (this especially avoids nasty patterns like
3105 `[tT][eE][sS][tT]'). Second two additional internal map functions
3106 `escape' and `unescape' were added which can be used to escape/unescape
3107 to/from hex-encodings in URLs parts (this is especially useful in
3108 combination with map lookups).
3109 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
3111 *) Renamed the macro escape_uri() to ap_escape_uri() which was
3112 forgotten (because it was a macro) in the symbol renaming process.
3113 [Ralf S. Engelschall]
3115 *) Fix some inconsistencies related to the scopes of directives. The only
3116 user visible change is that the directives `UseCanonicalName' and
3117 `ContentDigest' now use the (more correct) `Options' scope instead of
3118 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
3120 *) Using DSO, the Server token was being mangled. Specifically, the
3121 module's token was being added first before the Apache token. This
3122 has been fixed. [Jim Jagielski]
3124 *) Major overhaul of mod_negotiation.c, part 2.
3125 - properly handle "identity" within Accept-Encoding.
3126 - allow encoded variants in RVSA negotiation and let them appear in
3127 the Alternates field using the non-standard "encoding" tag-list.
3128 - fixed both negotiation algorithms so that an explicitly accepted
3129 encoding is preferred over no encoding if "identity" is not
3130 included within Accept-Encoding.
3131 - added ap_array_pstrcat() to alloc.c for efficient concatenation
3132 of large substring sequences.
3133 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
3136 *) Major overhaul of mod_negotiation.c, part 1.
3137 - cleanups to mod_negotiation comments and code structure
3138 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
3139 support for everything in the upcoming HTTP/1.1
3140 revision (draft-ietf-http-v11-spec-rev-06.txt).
3141 - language tag matching also handles tags with more than 2
3143 - empty Accept, Accept-Language, Accept-Charset headers are
3144 processed correctly; previously an empty header would make all
3145 values acceptable instead of unacceptable.
3146 - allowed for q values in Accept-Encoding
3147 - added support for transparent content negotiation (rfc2295 and
3148 rfc2296) (though we do not implement all features in these drafts,
3149 e.g. no feature negotiation). Removed old experimental version.
3150 - implemented 'structured entity tags' for better cache correctness
3151 (structured entity tags ensure that caches which can deal with Vary
3152 will (eventually) be updated if the set of variants on the server
3154 - this involved adding a vlist_validator element to request_rec
3155 - this involved adding the ap_make_etag() function to the global API
3156 - modified guessing of charsets used by Apache negotiation algorithm
3157 to guess 'no charset' if the variant is not a text/* type
3158 - added code to sort multiviews variants into a canonical order so that
3159 negotiation results are consistent across backup/restores and mirrors
3160 - removed possibility of a type map file resolving to another type map
3161 file as its best variant
3162 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
3164 *) RFC2396 allows the syntax http://host:/path (with no port number)
3165 but the proxy disallowed it (ap_proxy_canon_netloc()).
3166 [David Kristol <dmk@bell-labs.com>] PR#3530
3168 *) When modules update/modify the file name in the configfile_t structure,
3169 syntax errors will report the updated name, not the original one.
3170 [Fabien Coelho <coelho@cri.ensmp.fr>] PR#3573
3172 *) Correct some filename case assumptions from WIN32 to
3173 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]
3175 *) For %v log ServerName regardless of the UseCanonicalName
3176 setting (similarly for %p). [Dean Gaudet]
3178 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
3179 rather late (too late for some invocations of TestCompile).
3180 This improves the make environment available to TestCompile and
3181 the *.module scripts. [Martin Kraemer]
3183 *) The hashbang emulation code in ap_execve.c would interpret
3184 #!/hashbang/scripts correctly, but failed to fall back to a
3185 standard shell for scripts which did NOT start with #!
3186 Now SHELL_PATH is started in these cases. [Martin Kraemer]
3188 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
3191 *) Update APXS manual page: some -q option arguments were missing
3192 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
3194 *) Cleanup the command line options: `-?' was documented to show
3195 the usage list but does it with an error because `?' is not a valid
3196 command. OTOH a lot of users expect `-h' to print such a usage list and
3197 instead are annoyed for ages by our huge unreadable list of directives.
3198 So we now changed the command line options this way:
3200 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
3201 very similar to the popular linker option.
3203 Intent: while -l gives the small list of modules, -L now gives the
3204 large list of directives implemented by these modules. This is also
3205 consistent with -v (short version info) and -V (large version info).
3207 Intent: it's now the expected option ;-)
3208 The manual page was adjusted accordingly.
3209 [Ralf S. Engelschall] PR#2714
3211 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
3212 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
3214 *) Removed recently introduced bugs and disfigurements in APACI:
3215 o fixed argument line processing: using $args was broken: It was not
3216 initialized and using args="$args $apc_option" and even args="$args
3217 \"$apc_option\"" fails in the second processing round for any arguments
3218 containing whitespaces. The only correct way is to use the construct
3219 "$@" (but not possible here) or iterate _both_ times over the implicit
3220 argument line (no argument to for-loop) which is what we now use.
3221 o make --with-layout=Apache the default without creating
3222 redundancy (copying the --with-layout block in the argument parsing
3223 loop). We achieve this by using the "$@" construct together with the
3224 `set' command to prepend --with-layout=Apache to the command line in
3225 case --with-layout is not used.
3226 o fixed auto-suffix handling now that config.layout exists.
3227 Paths which are auto-suffixed are marked with a trailing plus sign in
3228 config.layout and every path now can be marked this way (not only the
3229 four paths for which we do it currently). Additionally the suffix is
3230 no longer a static one. Instead it's now `/<target>' where <target> is
3231 the argument of the --target option or per default `httpd'.
3232 o allow also tabs (and only spaces) where we match whitespaces
3233 o various fixes and cleanups related to used shell coding style
3234 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
3235 o trimmed output of --help to fit into 80 columns
3236 [Ralf S. Engelschall]
3238 *) Added two new core API functions, ap_single_module_configure() and
3239 ap_single_module_init(), which are now used by mod_so to configure a module
3240 after loading. [Ralf S. Engelschall]
3242 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
3243 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
3244 of ap_config.h to allow serialized accept for multiport listens.
3245 [Roy Fielding, Curt Sampson] PR#3120
3247 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
3248 of ap_config.h that would skip several defines if DEFAULT_GROUP
3249 was overridden. [Roy Fielding]
3251 *) PORT: The I86 version of DGUX has support for strncasecmp and
3252 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
3254 *) Fix ordering of definitions in ap_config.h so that ap_inline is
3255 defined before it might be used. [Victor Khimenko]
3257 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
3258 [Tom Serkowski <tks@bsdi.com>] PR#3453
3260 *) Make generation of src/Configuration.apaci more robust: It failed to
3261 differenciate between modules when one module name was a postfix of
3262 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
3263 just XXX (think about totally non-standard names like "apache_ssl", too).
3264 [Ralf S. Engelschall] PR#3380
3266 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
3267 since 1.3b7) and make whitespace handling more robust (it failed horrible
3268 when whitespaces were present in the arguments of -D options).
3269 [Ralf S. Engelschall] PR#3240
3271 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
3272 creates an external package shadow tree in DIR before the local build
3273 shadow tree is generated under DIR. This way one can have the extracted
3274 Apache distribution tree read-only on NFS or CDROM and still build Apache
3275 from these sources. An automatically triggered VPATH-like mechanism is
3276 provided through the TOP variable, too.
3277 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez@apple.com>]
3279 *) Fix negotiation so that a Vary response header is correctly
3280 generated when, for a particular dimension, variants only vary
3281 in having or not having a value for that dimension. [Paul Sutton]
3283 *) Fix negotiation so that we prefer an encoded variant over an
3284 unencoded variant if the user-agent explicitly says it can
3285 accept that encoding. Previously we always preferred the unencoded
3287 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
3289 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
3290 and the usage page was inconsistent with the functionality and manpage.
3291 [Ralf S. Engelschall]
3293 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
3294 They can occur multiple times and their arguments (`xxx') are passed AS
3295 IS to the compiler/linker command. [Ralf S. Engelschall]
3297 *) Fixed possible (but harmless in practice) bug in the DBM lookup
3298 procedure of mod_rewrite: very long keys were truncated.
3299 [Ralf S. Engelschall]
3301 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
3302 identifier, currently "Apache" and "GNU" are pre-defined in the file
3303 config.layout. Custom layouts are possible by using FILE:ID as the
3304 argument where the layout ID is taken from FILE.
3306 The config.layout file consists of <Layout ID>..</Layout> sections
3307 where inside those sections "path_variable: path_value" pairs can be
3308 specified. These lines are converted to path_variable='path_value'.
3310 *) Add a DefaultLanguage directive so that files missing a language
3311 extension (e.g., .fr, .de) can be labelled as being some other
3312 default language. DefaultLanguage can appear in <Directory> and
3313 <Files> containers as well as .htaccess files. [Paul Sutton]
3316 *) Fix TARGET configuration when configuring and installing using
3317 APACI configure. TARGET now defines the basename of the configuration
3318 file, startup script, manual page, etc. log_error_core() now reports
3319 the server binary name given by argv[0]. TARGET can now also be defined
3320 with --target=TARGET parameter passed to APACI configure.
3321 [Ralf Engelschall, Randy Terbush]
3323 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
3324 rather than OPT_INCLUDES [Rainer Schoepf <schoepf@uni-mainz.de>]
3326 *) ap_md5_binary() was using sprintf() rather than a table lookup
3327 to convert binary bytes to hex digits.

3346 *) Fallback to native compilers for IRIX-32 platform. It seems that
3347 a gcc 2.8.1 compiled apache is logging client addresses with all
3348 bits set (255.255.255.255). This is the second such problem caused

3359 *) Add APACI --suexec-docroot and --suexec-logfile options which can be
3360 used to set the document root directory (DOC_ROOT) and the suexec
3361 logfile (LOG_EXEC), respectively. Additionally the --layout option
3362 was changed to show more information about the suEXEC setup.

3370 modules, Limit, and Script directives. That includes PATCH,
3371 PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.
3372 Improved mod_actions.c so that it can use any of the methods

3400 since it often includes file path info. Enable sending of error-notes
3401 on a 501 (Method Not Implemented). [Roy Fielding] PR#3173
3403 *) http_config.c would respond with 501 (Method Not Implemented) if a
3404 content type handler was specified but could not be found, which
3405 should have been a 500 response. Likewise, mod_proxy.c would responsd
3406 with a 501 if the URI scheme is unrecognized instead of the correct
3407 response of 403 (Forbidden). [Roy Fielding]

3429 supported for the option argument: first BEGIN:foo which permutes module
3430 mod_foo with the begin of the module list, i.e. it `moves' the module to
3431 the begin of the list (gives it lowest priority). And second foo:END
3432 which permutes mod_foo with the end of the module list, i.e. it `moves'
3433 the module to the end of the list (gives it highest priority).

3508 response when we already know the final status, which is mighty
3509 useful for PUT responses that result in 302 or 401. [Roy Fielding]
3511 *) Remove extra trailing whitespace from the getline results as part
3512 of the protocol processing, which is extra nice because it works
3513 between continuation lines, is almost no cost in the normal case
3514 of no extra whitespace, and saves memory. [Roy Fielding]
3516 *) Added new HTTP status codes and default response bodies from the
3517 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
3518 HTTP Extension Framework (510) specifications. Did not add the
3519 WebDAV 424 and 425 codes because they are bogus. We don't use any
3520 of these codes yet, but they are now available to 3rd-party modules.

3636 You now must define a BS2000Account name for the server User.
3637 This has fewer security implications than the old approach.
3640 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
3641 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
3642 platform to make the braindead HPUX linker happy. Notice, for the module
3643 DSOs we don't have to use this, because these are loaded manually (and

3655 *) Make PrintPath work generically instead of having one version
3656 strictly for OS/2. [Jim Jagielski, Brian Havard]
3658 *) Fix the recently introduced C header file checking: We now use the C
3659 pre-processor pass only (and no longer the complete compiler pass) to
3660 determine whether a C header file exists or not. Because only this way
3661 we're safe against inter-header dependencies (which caused horrible
3662 portability problems). The only drawback is that we now have a CPP
3663 configuration variable which has to be determined first (we do a similar
3664 approach as GNU Autoconf does here). When all fails the user still has
3665 the possibility to override it manually via APACI or src/Configuration.
3666 As a fallback for the header check itself we can directly check the
3667 existance of the file under /usr/include, too.

3707 (instead it directly passes through the message to be formatted to the
3708 real internal formatting function). [Ralf S. Engelschall] PR#2941
3710 *) Allow "Include" directives anywhere in the server config
3711 files (but not .htaccess files). [Ken Coar] PR#2727
3713 *) The proxy was refusing to serve CONNECT requests except to
3714 port 443 (https://) and 563 (snews://). The new AllowCONNECT
3715 directive allows the configuration of the ports to which a
3716 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
3718 *) mod_expires will now act on content that is not sent from a file
3719 on disk. Previously it would never add an Expires: header to
3720 any response that did not come from a file on disk; the only
3721 case where it still doesn't (and can't) add one for that type of
3722 content is if you are using a modification date based setting.
3723 [Marc Slemko, Paul Phillips <paulp@go2net.com>]

3726 that lead to a "500 Server Error" condition now provide explanatory
3727 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
3730 *) Add NameWidth keyword to IndexOptions directive so that the

3734 *) Recognize lowercase _and_ uppercase `uname' results under
3735 SCO OpenServer. [David Coelho <drc@ppt.com>]
3737 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
3738 a common problem of (mis-administrated?) IIS servers, make the apache
3739 proxy immune to these errors (and ignore the duplicates, but log
3740 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
3742 *) The <IfModule and <IfDefine block starting directives now only
3743 allow exactly one argument. Previously, the optional negation
3744 character '!' could be separated by whitespace without a syntax
3745 error being reported, albeit defeating the IfModule functionality
3746 (enclosed directives would ALWAYS be executed). By using the
3747 stricter syntax, these hard-to-track errors can be avoided.
3750 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
3751 cause the standalone FancyIndexing directive to logically OR
3752 into any existing IndexOptions settings rather than wiping
3753 them out. [Ken Coar]
3755 *) Changes in ftp proxy: make URL parsing simpler by using the
3757 + Add display of the "current directory" in cases where it's
3758 different from the supplied path (e.g., ftp://user@host/ lives
3759 in /home/user, not in /, therefore clicking on "../" in the
3760 starting directory might send us to /home/).
3761 + When ftp login fails, (esp. when a user name was part of the
3762 URL already), we now return [401 Unauthorized ] to allow the
3763 browser to pop up an authorization dialog. This makes passwords
3764 slightly less visible (they don't appear in the regular log files)
3765 and implements a functionality that other www proxy servers
3769 *) Triggered by the recent "Via:" header changes, the proxy module would
3770 dump core for replies with invalid headers (e.g., duplicate
3771 "HTTP/1.0 200 OK" lines). These errors are now logged and the
3772 core dump is avoided. Also, broken replies are not cached.

3808 5 to 10 because there are some users out there who always have 5 to 8
3809 variables in one RewriteRule and had to patch mod_rewrite.h for every

3833 compile time, for least astonishment of the user.
3836 *) When READing a request in ExtendedStatus mode, the "old"
3837 vhost, request and client information is not displayed.
3840 *) STATUS is no longer available. Full status information now
3841 run-time configurable using the ExtendedStatus directive.
3844 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
3845 cpu time attacks) in header parsing. Add ap_overlap_tables(),
3846 a function which can be used to perform bulk update operations
3847 on tables in a more efficient manner. [Dean Gaudet]
3849 *) SECURITY: Added compile-time and configurable limits for
3850 various aspects of reading a client request to avoid some simple
3851 denial of service attacks, including limits on maximum request-line

4221 than strcmp() to check for parent directory-ness of an entry. Oh, and
4222 make sure the parent directory (if displayed) is *always* listed first
4223 regardless of the sort key. Overall performance winnage should be good
4224 in CPU time, instruction cache, and memory usage, particularly for large
4225 directories. [Ken Coar]

4234 *) Add httpd -t (test) option for running configuration syntax tests only.
4235 If something is broken it complains and exits with a return code
4236 non-equal to 0. This can be used manually by the user to check the Apache
4237 configuration after editing and is also automatically used by apachectl
4238 on (graceful) restart command to make sure Apache doesn't die on restarts
4239 because of a configuration which is now broken since the last (re)start.
4240 This way `apachectl restart' can be used inside cronjobs without having

4353 *) Change usage of perror()+fprintf(stderr,...) in mod_rewrite to
4354 more proper ap_log_error() variants.
4355 [Ralf S. Engelschall]
4357 *) Make sure the argument for the --add-module option to APACI's configure

4380 ap_spawn_child_err became ap_spawn_child
4381 ap_spawn_child_err_buff became ap_bspawn_child
4382 spawn_child was obsoleted and moved to compat.h
4385 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
4386 programs: ap_spawn_child_err() is used and the Win32 case now uses
4387 CreateProcess() instead of a low-level execl() (which caused problems in
4388 the past under Win32).

4391 *) A few cosmetics and trivial enhancements to APXS to make the
4392 generated Makefile more user friendly. [Ralf S. Engelschall]
4394 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
4395 was updated to use the normal apache error processing, thereby allowing
4396 proxy errors to be treated by ErrorDocument's as well. For this
4397 purpose, a new module-to-core communication variable "error-notes"
4398 was introduced; the proxy (and possibly other modules) communicates
4399 its error text using this variable. Its content is copied to a new
4400 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
4401 The old proxy special error routine ap_proxy_log_uerror()
4402 was replaced by regular ap_log_error() calls, many messages were made

4411 ("make") of Apache we can allow, of course. Root privileges are needed
4412 only for the installation step ("make install"). So make sure the

4474 instead of C file descriptors.
4475 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
4477 *) The proxy cache would store an incorrect content-length in the cached
4478 file copy after a cache update. That resulted in repeated fetching
4479 of the original copy instead of using the cached copy.
4480 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
4482 *) The Makefiles assumed that DSO files are build via $(LD). This
4483 is broken for two reasons: First we never defined at least LD=ld
4484 somewhere to make sure this works (it was silently assumed that most Make
4485 provide a built-in LD definition - ARGL!) and second using the generic LD
4486 variable is not the truth. Instead a special variable named LD_SHLIB is
4487 reasonable because although "ld" is usually the default, the command for
4488 building DSO files can be "libtool" or even "cc" on some systems.
4489 [Ralf S. Engelschall]
4491 *) Replace the AddVersionPlatform directive with ServerTokens which
4492 provides for more control over the format of the Server:

4495 API function instead. [Jim Jagielski]

4501 not retrieved in src/Configure and thus was not useable.
4502 [Ralf S. Engelschall]
4504 *) Various Makefile consistency cleanups:
4505 - make OSDIR also automatically be relative to src/ like INCDIR
4506 - SUBDIRS is now generated in src/Makefile only and not in
4507 Makefile.config because it is a local define for this location.
4508 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
4509 any Makefile but make sure that at least the "-K inline" is kept in
4511 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
4512 - updated the dependencies theirself
4513 - removed not existing SHLIB variable from "clean" targets
4514 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
4515 already exists and OBJS_PIC are also just plain objects and have not
4516 directly to do with "shared" things. The only difference is that they
4517 contain PIC. So OBJS_PIC is the more canonical name.
4518 - Updated the Makefile-dependency lines for OBJS_PIC
4519 - Removed the Makefile-dependency line in Configure to avoid double
4521 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
4522 of xxx.lo as GNU libtool does with its PIC objects
4523 - reduce local complexity in modules Makefile.tmpl by moving the last
4524 existing target "depend" to the generation section in Configure, too.
4525 - removed the historical $(SPACER) which was used in the past together
4526 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
4527 is no longer needed.
4528 - force the build and run of the gen_xxx programs under main/ as the
4529 first step before building the objects because it looks cleaner
4530 [Ralf S. Engelschall]
4532 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
4535 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
4538 *) WIN32: Don't force ISAPI headers to finish with \n.
4539 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
4541 *) When opening "configuration" files (like httpd.conf, htaccess
4542 and htpasswd), Apache will not allow them to be non-/dev/null
4543 device files. This closes a DoS hole. At the same time,
4544 we use ap_pfopen to open these files to handle timeouts.
4545 [Jim Jagielski, Martin Kraemer]
4547 *) Apache will now log the reason its httpd children exit if they exit
4548 due to an unexpected signal. (It requires a new porting define,
4549 SYS_SIGLIST, which if defined should point to a list of text
4550 descriptions of the signals available. See PORTING.) [Dean Gaudet]
4552 *) WIN32: chdir() doesn't make sense in a multithreaded environment
4553 like WIN32. Before, Win32 CGI's could have had sporadic failures
4554 if a chdir call from one thread was made between another chdir call
4555 and a spawn in another thread. So, for now don't chdir for CGI scripts
4556 in WIN32. The current CGI "spec" is unclear as to whether it's
4557 necessary. Long-term fix is to either serialize the chdir/spawn combo
4558 or use WIN32 native calls to spawn a process. This temp fix was
4559 necessary to remove this as a showstopper for 1.3's release.
4562 *) Cleanup the suEXEC support in APACI and make it more safe:
4563 1. Add big fat hint in INSTALL about risks and to read the
4564 htdocs/manual/suexec.html document before using the suexec-related
4566 2. Make sure the user has at least provided one --suexec-xxxx option
4567 (specifies suEXEC parameters) in addition to --enable-suexec option.
4568 If only --enable-suexec is given APACI stops with a hint to INSTALL
4569 and htdocs/manual/suexec.html documents.
4570 3. Provide two additional --suexec-xxxx options to make the suEXEC
4571 configuration complete (especially for package maintainers who else
4572 had to patch the source tree) by providing ways to configure minimal
4573 UID/GID and safe PATH, too.
4574 [Ralf S. Engelschall]
4576 *) Cleanup of the `configure --shadow' process:
4577 - make sure the configure script creates its temporary files in the
4578 shadow tree to avoid conflicts with parallel configure runs
4579 - removed unnecessary option "-r" from "rm" call for Makefiles
4580 - make sure the configure scripts creates the shadow-wrapper Makefile
4581 only when no shadow trees already exists
4582 - make sure "make distclean" removes the shadow-wrapper Makefile but only
4583 when no more shadow trees exists
4584 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
4585 as fast (in the past it needed 70sec, now it runs just 38sec)
4586 - make sure CVS does not complain about the created files
4587 Makefille.<gnutriple> and directories src.<gnutriple>
4588 [Ralf S. Engelschall]
4590 *) Added the ap_add_version_component() API routine and the
4591 AddVersionPlatform core directive. The first allows modules to
4592 declare themselves in the Server response header field value,
4593 augmenting the SERVER_SUBVERSION define in the Configuration file
4594 with run-time settings (more useful in a loadable-module environment).
4595 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
4596 into the server version string. [Ken Coar] PR#2056
4598 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
4601 *) Emit the "Accept-Range" header for the default handler.
4602 [Brian Behlendorf] PR#1464
4604 *) Add a note to httpd.conf-dist that apache will on some systems fail
4605 to start when the Group # is set to a negative or large positive value.
4608 *) Make sure the module execution order is correct even when some modules
4609 are loaded under runtime (`LoadModule') via the DSO mechanism:
4610 1. The list of loaded modules is now a dynamically allocated one
4611 and not the original statically list from modules.c
4612 2. The loaded modules are now correctly setup by LoadModule for
4613 later use by the AddModule command.
4614 3. When the DSO mechanism for modules is used APACI's `install'
4615 target now enables all created `LoadModule' lines per default because
4616 this is both already expected by the user _and_ needed to avoid
4617 confusion with the next point and reduces the Makefile.tmpl complexity
4618 4. When the DSO mechanism for modules is used, APACI's `install'
4619 target now additionally makes sure the module list is reconstructed
4620 via a complete `ClearModuleList+AddModule...' entry.
4621 5. The support tool `apxs' now also makes sure an AddModule command
4622 is added in addition to the LoadModule command.
4623 6. The modules.c generation was extended to now contain two
4624 comments to make sure no one is confused by the confusing terminology
4625 of loading/linking (we use load=link+load & link=activate instead of
4626 the obvious load=activate & link=link :-( )
4627 This way now there is no longer a difference under execution time between
4628 statically and dynamically linked modules.
4629 [Ralf S. Engelschall]
4631 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
4632 Big Symbol Renaming. [Ralf S. Engelschall]
4634 *) Add a comment to mod_example.c showing the format of a FLAG command
4637 *) Standardized the time format in mod_status to match that of other
4638 places in the code (e.g. DATE_GMT). PR#1551
4640 *) Fix handling of %Z in timefmt strings for those platforms with no time
4641 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
4644 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
4645 feature compatible with 'UseCanonicalName off' by changing
4646 r->server->server_hostname to ap_get_server_name(). And I changed some
4647 functions which use r->server->port to use ap_get_server_port() instead,
4648 because if there's no Port directive in the config r->server->port is 0.
4651 *) get/set_module_config are trivial enough to be better off inline. Worth
4652 1.5% performance boost. [Dean Gaudet]
4654 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
4655 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
4658 *) [BS2000 security] BS2000 needs an extra authentication to initialize
4659 the task environment to the unprivileged User id. Otherwise CGI scripts
4660 would have a way to gain super user access. [Martin Kraemer]
4662 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
4663 absolute path, only log base name of logging source as is done
4664 in unix. [Martin Kraemer]
4666 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
4667 the encoding type from the Accept-Encoding header (if it's there)
4668 and use it in the response, as that's probably what it'll be expecting.
4669 [Ronald.Tschalaer@psi.ch]
4671 *) Fix to mod_alias: translate_alias_redir is dealing with
4672 a URI, not a filename, so the check for drive letters for win32
4673 and emx is not necessary. [Dean Gaudet]
4675 *) WIN32: Allow .cmd as an executable extension.
4676 [Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146
4678 *) Make Apache header files, and some variables, C++ friendly.
4679 [Michael Anderson's <mka@redes.int.com.mx>]
4681 *) Child processes can now "signal" (by exiting with a status
4682 of APEXIT_CHILDFATAL) the parent process to abort and
4683 shutdown the server if the error in the child process was
4684 fatal enough. [Jim Jagielski]
4686 *) mod_autoindex's find_itme() was sensitive to MIME type case.
4687 [Jim Jagielski] PR#2112
4689 *) Make sure the referer_log and agent_log entries in the default httpd.conf
4690 file are also adjusted for the actual relative installation paths.
4691 [Ralf S. Engelschall] PR#2175
4693 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
4695 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
4698 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
4699 Additionally the checks for finding the vendor DSO library were moved
4700 from mod_so.c to Configure because first it needs $PLAT etc. and second
4701 mod_so already uses an abstraction layer and does not fiddle with the
4702 vendor functions itself.
4703 [Jens-Uwe Mager, Ralf S. Engelschall]
4705 *) PORT: Some optimization defines for NetBSD
4706 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
4708 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
4709 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
4711 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
4712 AIX variants should work fine, too. Even AIX 3.x should work). This is
4713 accomplished by using the free DSO emulation code from Jens-Uwe Mager
4714 which we put into a os/unix/os-dso-aix.c file.
4715 [Ralf S. Engelschall]
4717 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
4718 that we should use NET_SIZE_T == int but the include files force size_t.
4719 [Ralf S. Engelschall]
4721 *) Fix two bugs in select() handling in http_main.c.
4724 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
4725 is unset (as it is in situations like timeouts) where it is unclear
4726 whether errno is set or not. [Martin Kraemer]
4728 *) Just having APACI's localstatedir is too general and not enough for most
4729 of the systems. 1.3b6 again required manual APACI patches by package
4730 maintainers from RedHat and FreeBSD because for their filesystem layout a
4731 little bit more flexibility in configuring the paths is needed. Hence we
4732 provide three additional configure options (--runtimedir, --logfiledir,
4733 --proxycachedir) which now can be used for more granular adjustments if
4734 --localstatedir is not enough to fit the particular needs. As a nice
4735 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
4736 [Ralf S. Engelschall]
4738 *) Make the install root for "make install" in APACI's Makefile overrideable
4739 by package authors. This way we are even more friendly to package
4740 maintainers (especially Debian and RedHat) who build for the real prefix
4741 via "configure --prefix=/<real>" but use a different local prefix via
4742 "make root=/tmp/apache install" for rolling the package without bristling
4743 the target location on their system.
4744 [Ralf S. Engelschall]
4746 *) Workaround sed limitations in APACI's configure script by now
4747 substituting in chunks of 50 commands (because for instance HPUX's vendor
4748 sed has a limit of max. 98 commands)
4749 [Ralf S. Engelschall] PR#2136
4751 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
4752 [Ralf S. Engelschall] PR#2140
4754 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
4755 RENAMING process because they are defined as pre-processor macros instead
4756 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
4757 [Ralf S. Engelschall]
4759 *) Workaround braindead AWK's when generating ap_config.h: The split() and
4760 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
4761 [Ralf S. Engelschall] PR#2139
4763 *) Various bugfixes and cleanups for the APACI configure script:
4764 o fix IFS handling for _nested_ situation
4765 o fix Perl interpreter search: take first one found instead of last one
4766 o fix DSO consistency check
4767 o print error messages to stderr instead of stdout
4768 o add install-quiet for --shadow situation to Makefile stub
4769 o reduce complexity by avoiding sed-hacks for rule and module list loops
4770 [Ralf S. Engelschall]
4772 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
4774 *) Make sure the input field separator (IFS) shell variable is explicitly
4775 initialized correctly before _every_ `for' loop and also restored after
4776 the loops. [Ralf S. Engelschall]
4778 *) Make sure that "make install" doesn't overwrite the `mime.types' and
4779 `magic' files from an existing Apache installation. Because people often
4780 customize these for own MIME and content types.
4781 [Ralf S. Engelschall]

4786 *) Fix the path to the ScoreBoardFile in the install-config target, too.
4787 [Ralf S. Engelschall] PR#2105
4789 *) Let "configure" clear out the users parameters (provided as shell
4790 variables) to avoid side-effects in "src/Configure" when the user
4791 exported them (which is not needed, but some users do it).
4792 [Ralf S. Engelschall] PR#2101
4794 *) Provide backward compatibility from some old src/Configuration.tmpl
4795 parameter names to the canonical Autoconf-style shell variable names. For
4796 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
4797 but a hint message is displayed. [Ralf S. Engelschall]

4800 CGI scripts from an existing Apache installation.
4801 [Ralf S. Engelschall, Jim Jagielski] PR#2084
4803 *) Make `configure --compat' more "compatible" by first
4804 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
4805 second by making sure the "avoid-bristling-suffix" /apache is not
4806 appended to sysconfdir, datadir, localstatedir and includedir when
4807 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]

4818 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
4820 *) If you start apache with the -S command line option it will dump
4821 out the parsed vhost settings. This is useful for folks trying
4822 to figure out what is wrong with their vhost configuration.
4823 (Other dumps may be added in the future.) [Dean Gaudet]
4825 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
4826 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
4829 *) Because /usr/local/apache is the default prefix the ``configure
4830 --compat'' option no longer has to set prefix, again. This way the
4831 --compat option honors a leading --prefix option. [Lars Eilebrecht]
4833 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
4834 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
4835 to avoid "discard const" warnings. [Ralf S. Engelschall]
4837 *) If a specific handler is set for a file yet the request still
4838 ends up being handled by the default handler, log an error
4839 message before handling it. This catches things such as trying
4840 to use SSIs without mod_include enabled. [Marc Slemko]
4842 *) Fix error logging for the startup case where ap_log_error() still uses
4843 stderr as the target. Now the default log level is honored here, too.
4844 [Ralf S. Engelschall]
4846 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
4847 long" errors when generating the MODULES entry for src/Makefile
4848 [Ben Hyde, Ralf S. Engelschall]
4850 *) Make sure src/Configure doesn't complain about the old directory
4851 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
4853 Changes with Apache 1.3b6
4855 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
4857 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
4858 interface via the similar but proprietary HP/UX shl_xxx-style system
4859 calls. [Ralf S. Engelschall]
4861 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
4862 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
4863 Make. [Ralf S. Engelschall]
4865 *) ++++ THE BIG SYMBOL RENAMING ++++
4866 To avoid symbol clashes with third-party code compiled into the server,
4867 we globally applied the prefix "ap_" to the following classes of
4869 - Apache provided general functions (e.g., ap_cpystrn)
4870 - Public API functions (e.g., palloc, bgets)
4871 - Private functions which we can't make static (because of
4872 cross-object usage) but should be (e.g., new_connection)
4873 For backward source compatibility a new header file named compat.h was
4874 created which provides defines for the old symbol names and can be used
4875 by third-party module authors.
4878 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
4879 problem under SVR4 is that there is no command flag to force the linker
4880 to export the global symbols of the httpd executable therewith they are
4881 available to the DSO's. Instead of problematic hacks like creating a
4882 dummy.so file (containing dummy references to all global symbols) the
4883 httpd binary is linked against, we use a clean trick stolen from Perl 5:
4884 Placing the Apache core code itself into a DSO library named libhttpd.so.
4885 This way the global symbols _HAVE_ to be exported and thus are available
4886 to any manually loaded DSO's under runtime. To reduce the impact to the
4887 user to null we go even further and create a stub httpd executable which
4888 automatically keeps track of the DSO library loading itself and thus
4889 hides the complete mechanism from the user. Although the generation of
4890 this DSO library is automatically triggered for platforms which
4891 essentially need it (mostly all SVR4-derivates) it can be also enabled
4892 manually via the Rule SHARED_CORE. This can be interesting in the future
4893 where we perhaps exploit this libhttpd.so mechanism for providing nifty
4894 features like graceful upgrades, or whatever.
4895 [Ralf S. Engelschall, Martin Kraemer]
4897 *) Build the libraries before building the rest of the tools. [Ben Hyde]
4899 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
4900 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
4901 conventions while "clean" removes only stuff created by "all" targets,
4902 "distclean" additionally removes the stuff from the configuration
4903 process. This way "make distclean" (hence the name) provides a fresh
4904 source tree as it was for distribution.
4905 [Ralf S. Engelschall]
4907 *) Allow top-level (APACI) Makefile to break on build errors
4908 the same way the src/ subtree Makefiles breaks on them by replacing the
4909 initial APACI sed-subdir-display-kludge with a more clean
4910 variable-passing-solution: variable SDP can optionally hold the subdir
4911 prefix which is consistently used for displaying the subdir movement.
4912 This way even the top-level Makefile can stop correctly on errors as the
4913 user expects. [Ralf S. Engelschall]
4915 *) Fixed ordering of argument checks for RewriteBase directive.
4916 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
4918 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
4919 indicating that a module is being compiled for dynamic loading. Also
4920 remove #define IS_MODULE from modules and add SHARED_MODULE define
4921 to the mak/dsp files. [Alexei Kosut]
4923 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
4924 since we are now logging APLOG_WARNING by default. [Roy Fielding]
4926 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
4928 *) Add documentation file and src/Configuration.tmpl entry for the
4929 experimental mod_mmap_static module. Because although it is and marked as
4930 an experimental one it is distributed and thus should be documented and
4931 prepared for configuration the same way as all others modules.
4932 [Ralf S. Engelschall]
4934 *) Add query (-q) option to apxs support tool to be able to manually query
4935 specific settings from apxs. This is needed for instance when you
4936 manually want to access Apache's header files and you need to assemble
4937 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
4938 [Ralf S. Engelschall]
4940 *) Now src/Configure uses a fallback strategy for the shared object support
4941 on platforms where no explicit information is available: If a Perl
4942 installation exists we ask it about its shared object support and if it's
4943 the dlopen-style one we shamelessly guess the compiler and linker flags
4944 for creating shared objects from Perls knowledge. Of course, the user is
4945 warning about what we are doing and informed that he should send us
4946 the guessed flags when they work. [Ralf S. Engelschall]
4948 *) Provide APACI --without-support option to be able to disable the build
4949 and installation of the support tools from the src/support/ area.
4950 Although its useful to have these installed per default we should provide
4951 a way to compile and install without them for backward-compatibility.
4952 [Ralf S. Engelschall]
4954 *) Add of the new APache eXtenSion (apxs) support tool for building and
4955 installing modules into an _already installed_ Apache package through the
4956 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
4957 this approach actually doesn't need the Apache source tree. The
4958 (APACI-installed) server package is enough, because this now includes the
4959 Apache C header files (PREFIX/include) and the new APXS tool
4960 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
4961 module authors to build their Apache modules _OUTSIDE_ the Apache source
4962 tree while avoiding them to fiddle around with the totally platform
4963 dependend way of compiling DSO files. The tool supports all ranges of
4964 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
4965 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
4966 on-the-fly generate a minimalistic Makefile and sample module for the
4967 first step to provide both a quick success event and to demonstrate the
4968 APXS mechanism to module authors. [Ralf S. Engelschall]
4970 *) Fix core dumps in use of CONNECT in proxy.
4971 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
4973 *) Modify the log directives in httpd.conf-dist files to use CustomLog
4974 so that users have examples of how CustomLog can be used.
4977 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
4978 the Apache distribution tree. Until Apache 1.3 there was no real
4979 out-of-the-box batch-capable build and installation procedure for the
4980 complete Apache package. This is now provided by a top-level "configure"
4981 script and a corresponding top-level "Makefile.tmpl" file. The goal is
4982 to provide a GNU Autoconf-style frontend which is capable to both drive
4983 the old src/Configure stuff in batch and additionally installs the
4984 package with a GNU-conforming directory layout. Any options from the old
4985 configuration scheme are available plus a lot of new options for flexibly
4986 customizing Apache. [Ralf S. Engelschall]
4988 *) The floating point ap_snprintf code wasn't threadsafe.
4989 Had to remove the HAVE_CVT macro in order to do threadsafe
4990 calling of the ?cvt() floating point routines. [Dean Gaudet]
4992 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
4994 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
4995 [Jim Jagielski] PR#1901
4997 *) BUG: Configure was using TCC and CC inconsistently. Make sure
4998 Configure knows which CC we are using. [Jim Jagielski]
5000 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
5001 was defined in a parent directory. [Lars Eilebrecht]
5003 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
5004 a generic printf-style routine that can call arbitrary output
5005 routines. Use this to replace http_bprintf.c. Add new routines
5006 psprintf(), pvsprintf() which allocate the exact amount of memory
5007 required for a string from a pool. Use psprintf() to clean up
5008 various bits of code which used ap_snprintf()/pstrdup().
5011 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
5012 ap_snprintf() has different semantics and formatting codes than
5013 snprintf(). [Dean Gaudet]
5015 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
5016 is necessary on at least Solaris where the /etc/rc?.d scripts
5017 are run with these signals ignored, and "SIG_IGN" settings are
5018 maintained across exec().
5019 [Rein Tollevik <reint@sys.sol.no>] PR#2009
5021 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
5022 used instead of lstat() and thus this flag didn't work as expected.
5023 [Rein Tollevik <reint@sys.sol.no>] PR#2010
5025 *) Fix the proxy pass-through feature of mod_rewrite for the case of
5026 existing QUERY_STRING now that mod_proxy was recently changed because of
5027 the new URL parsing stuff. [Ralf S. Engelschall]
5029 *) A few changes to scoreboard definitions which helps gcc generate
5030 better code. [Dean Gaudet]
5032 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
5033 be a signed bitfield. So mark a few bitfields as signed to
5034 ensure correct code. [Dean Gaudet]
5036 *) The default for HostnameLookups was changed to Off, but there
5037 was a problem and it wasn't taking effect. [Dean Gaudet]
5039 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
5042 *) After a SIGHUP the listening sockets in the parent weren't
5043 properly marked for closure on fork().
5044 [Jürgen Keil <jk@tools.de>] PR#2000
5046 *) Allow %2F in two situations: 1) it is in the query part of the URI,
5047 therefore not exposed to %2F -> '/' translations and 2) the request
5048 is a proxy request, so we're not dealing with a local resource anyway.
5049 Without this, the proxy would fail to work for any URL's with
5050 %2f in them (occurs quite often in
5051 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
5053 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
5055 *) Make the shared object compilation command more portable by avoiding
5056 the direct combination of `-c' & `-o' which is not honored by some
5057 compilers like UnixWare's cc. [Ralf S. Engelschall]
5059 *) WIN32: the proxy was creating filenames missing the last four
5060 characters. While this normally doesn't stop anything from
5061 working, it can result in extra collisions.
5062 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
5064 *) Now mod_proxy uses the response string (in addition to the response status
5065 code) from the already used FTP SIZE command to setup the Content-Length
5066 header if available. [Ralf S. Engelschall] PR#1183
5068 *) Reanimated the (still undocumented) proxy receive buffer size directive:
5069 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
5070 name was really too generic, added documentation for this directive to
5071 the mod_proxy.html and corrected the hyperlink to it in the
5072 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
5074 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
5075 faster [Martin Kraemer]
5077 *) Make Configure die when you give it an unknown command switch.
5080 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
5081 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
5082 and per default compiled support programs have manual pages - just to
5083 document our stuff a little bit more and to be able to do really
5084 Unix-like installations ;-) [Ralf S. Engelschall]
5086 *) Major cleanups to the Configure script to make it and its generated
5087 Makefiles again readable and maintainable: add SRCDIR option, removed
5088 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
5089 generated sections, consequently added Makefile headers with inheritance
5090 information, added subdir movement messages for easier following where
5091 the build process currently stays (more verbose then standard Make, less
5092 verbose than GNU make), same style to comments in the Configure script,
5093 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
5095 *) Add the new ApacheBench program "ab" to src/support/: This is derived
5096 from the ZeusBench benchmarking program and can be used to determine the
5097 response performance of an Apache installation. This version is
5098 officially licensed with Zeus Technology, Ltd. See the license agreement
5099 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
5100 [Ralf S. Engelschall]
5102 *) API: Various core functions that are definately not part of the API
5103 have been made static, and a few have been marked API_EXPORT. Still
5104 more have been marked CORE_EXPORT and are not intended for general
5105 use by modules. [Doug MacEachern, Dean Gaudet]
5107 *) mod_proxy was not clearing the Proxy-Connection header from
5108 requests; now it does. This did not violate any spec, however
5109 causes poor interactions when you are talking to remote proxies.
5110 [Marc Slemko] PR#1741
5112 *) Various cleanups to the command line interface and manual pages.
5113 [Ralf S. Engelschall]
5115 *) cfg_getline() was not properly handling lines that did not end
5116 with a line termination character. [Marc Slemko] PR#1869, 1909
5118 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
5120 *) Clean up some undocumented behavior of mod_setenvif related to
5121 "merging" two SetEnvIf directives when they match the same header
5122 and regex. Document that mod_setenvif will perform comparisons in
5123 the order they appear in the config file. Optimize mod_setenvif by
5124 doing more work at config time rather than at runtime.
5127 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
5128 to allow for modules to overrule them and to reduce redefinition
5129 warnings [Jim Jagielski]
5131 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
5134 *) Making the hard-coded cross-module function call mime_find_ct() (from
5135 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
5136 checking is really called even for proxy requests except for URLs with
5137 HTTP schemes (because there we can optimize by not running the type
5138 checking hooks due to the fact that the proxy gets the MIME Content-type
5139 from the remote host later). This change cleans up mod_mime by removing
5140 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
5141 especially unbundles mod_proxy and mod_mime. This way they both now can
5142 be compiled as shared objects and are no longer tied together.
5143 [Ralf S. Engelschall]
5145 *) util.c cleanup and speedup. [Dean Gaudet]
5147 *) API: Clarification, pstrndup() will always copy n bytes of the source
5148 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
5150 *) Mark module command_rec and handler_rec structures const so that they
5151 end up in the read-only data section (and are friendlier to systems
5152 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
5154 *) Add check to the "Port" directive to make sure the specified
5155 port is in the appropriate range. [Ben Hyde]
5157 *) Performance improvements to invoke_handler().
5158 [Dmitry Khrustalev <dima@bog.msu.su>]
5160 *) Added support for building shared objects even for library-style modules
5161 (which are built from more than one object file). This now provides the
5162 ability to build mod_proxy as a shared object module. Additionally
5163 modules like mod_example are now also supported for shared object
5164 building because the generated Makefiles now no longer assume there is at
5165 least one statically linked module. [Ralf S. Engelschall]
5167 *) API: Clarify usage of content_type, handler, content_encoding,
5168 content_language and content_languages fields in request_rec. They
5169 must always be lowercased; and the strings pointed to shouldn't
5170 be modified (you must copy them to modify them). Fix a few bugs
5171 related to this. [Dean Gaudet]
5173 *) API: Clarification: except for RAW_ARGS, all command handlers can
5174 treat the char * parameters as permanent, and modifiable. There
5175 is no need to pstrdup() them. Clean up some needless pstrdup().
5178 *) Now mod_so keeps track of which module shared objects with which names
5179 are loaded and thus avoids multiple loading and unloading and irritating
5180 error_log messages. [Ralf S. Engelschall]
5182 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
5183 environment variable in the apache core. But that tweaking interferes
5184 with mod_setenv. So don't tweak if the user has specified an explicit
5185 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888

5192 it to the IP address when unavailable.
5193 [Tony Finch <fanf@demon.net>] PR#1925
5195 *) Various improvements to the configuration and build support for compiling
5196 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
5197 OSF1 support with GCC and vendor compilers was added. This way shared
5198 object support is now provided out-of-the-box for FreeBSD, Linux,
5199 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
5200 [Ralf S. Engelschall]
5202 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
5203 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
5204 and USE_OS2_SCOREBOARD. [Dean Gaudet]
5206 *) Fix one more special locking problem for RewriteMap programs in
5207 mod_rewrite: According to the documentation of flock(), "Locks are on
5208 files, not file descriptors. That is, file descriptors duplicated
5209 through dup(2) or fork(2) do not result in multiple instances of a lock,
5210 but rather multiple references to a single lock. If a process holding a
5211 lock on a file forks and the child explicitly unlocks the file, the
5212 parent will lose its lock.". To overcome this we have to make sure the
5213 RewriteLock file is opened _AFTER_ the childs were spawned which is now
5214 the case by opening it in the child_init instead of the module_init API
5215 hook. [Ralf S. Engelschall] PR#1029
5217 *) Change to Location and LocationMatch semantics. LocationMatch no
5218 longer lets a single slash match multiple adjacent slashes in the
5219 URL. This change is for consistency with RewriteRule and
5220 AliasMatch. Multiple slashes have meaning in URLs that they do
5221 not have in (some) filesystems. Location on the other hand can
5222 be considered a shorthand for a more complicated regex, and it
5223 does match multiple slashes with a single slash -- which is
5224 also consistent with the Alias directive.

5227 *) Fix bug with mod_mime_magic causing certain files, including files
5228 of length 0, to result in no response from the server.
5231 *) The Configure script now generates src/include/ap_config.h which
5232 contains the set of defines used when Apache is compiled on a platform.
5233 This file can then be included by external modules before including
5234 any Apache header files in case they are being built separately from
5235 Apache. Along with this change, a couple of minor changes were
5236 made to make Apache's #defines coexist peacefully with any autoconf
5237 defines an external module might have. [Rasmus Lerdorf]
5239 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
5240 but without any RewriteXXXXX directives. Here mod_rewrite is given no
5241 chance by the API to initialize its per-server configuration and thus
5242 receives the wrong one from the main server. This is now avoided by
5243 remembering the server together with the config structure while
5244 configuring and later assuming there is no config when we see a
5245 difference between the remembered server and the one calling us.
5246 [Ralf S. Engelschall] PR#1790
5248 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
5249 is automatically disabled under configure time when the dbm_xxx functions
5250 are not available. Second, two heavy source code errors in the DBM
5251 support code were fixed. This makes DBM RewriteMap's usable again after
5252 a long time of brokenness. [Ralf S. Engelschall] PR#1696
5254 *) Now all configuration files support Unix-style line-continuation via
5255 the trailing backslash ("\") character. This enables us to write down
5256 complex or just very long directives in a more readable way. The

5276 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
5277 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
5278 up static content only servers. Or it may fail unpredictably.

5281 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
5284 *) API: Rewrite of absoluteURI handling, and in particular how
5285 absoluteURIs match vhosts. Unless a request is a proxy request, a
5286 "http://host" url is treated as if a similar "Host:" header had been
5287 supplied. This change was made to support future HTTP/1.x protocols
5288 which may require clients to send absoluteURIs for all requests.
5290 In order to achieve this change subtle changes were made to the API. In a
5291 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
5292 that the unmodified uri can be retrieved easily. r->proxyreq is not set
5293 by the core, modules must set it during the post_read_request or
5294 translate_names phase.
5296 Plus changes to the virtualhost test suite for absoluteURI testing.
5298 This fixes several bugs with the proxy proxying requests to vhosts
5299 managed by the same httpd.

5322 parts. These parts are stored in a uri_components structure called
5323 parsed_uri within each request_rec, and are available to all modules.
5324 Additionally, an unparse routine is supplied which re-assembles the URI
5325 components back to an URI, optionally hiding the username:password@ part
5326 from ftp proxy requests, and other useful routines. Within the structure,
5327 you find on a ready-for-use basis:
5328 scheme; /* scheme ("http"/"ftp"/...) */
5329 hostinfo; /* combined [user[:password]@]host[:port] */
5330 user; /* user name, as in http://user:passwd@host:port/ */
5331 password; /* password, as in http://user:passwd@host:port/ */
5332 hostname; /* hostname from URI (or from Host: header) */
5333 port_str; /* port string (integer representation is in "port") */
5334 path; /* the request path (or "/" if only scheme://host was given) */
5335 query; /* Everything after a '?' in the path, if present */
5336 fragment; /* Trailing "#fragment" string, if present */
5337 This is meant to serve as the platform for *BIG* savings in
5338 code complexity for the proxy module (and maybe the vhost logic).
5341 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
5342 ${map:key}) available for all location where a string is created in
5343 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
5344 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
5345 possible expansions are consequently usable at all string creation
5346 locations. [Ralf S. Engelschall]
5348 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
5349 and not 1) and the per-virtual-server merging of directives. Now all
5350 directives except `RewriteEngine' and `RewriteOption' are either
5351 completely overridden (default) or completely inherited (when
5352 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325
5354 *) Fix `RewriteMap' program lookup in situations where such maps are
5355 defined but disabled (`RewriteEngine off') in per-server context.
5356 [Ralf S. Engelschall] PR#1431
5358 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause
5359 server to bind to port 0 rather than 80. [Dean Gaudet]
5361 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
5362 (like SunOS and FreeBSD) which don't accept the locking of pipes
5363 directly. A new directive RewriteLock is introduced which can be used to
5364 setup a separate locking file which then is used for synchronization.
5365 [Ralf S. Engelschall] PR#1029
5367 *) WIN32: The server root is obtained from the registry key
5368 HKLM\SOFTWARE\Apache Group\Apache\<version> (version is currently
5369 "1.3 beta"), unless overridden by the -d command line flag. The
5370 value is stored by running "apache -i -d serverroot". [Paul Sutton]
5372 *) Merged os/win32/mod_dll.c into modules/standard/mod_so.c to support
5373 dynamic loading on Win32 and Unix via the same module. [Paul Sutton]
5375 *) Now mod_rewrite no longer makes problematic assumptions on the characters
5376 a username can contain when trying to expand it via /etc/passwd.
5377 [Ralf S. Engelschall]
5379 *) The mod_setenvif BrowserMatch backwards compatibility command did not
5380 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
5382 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
5383 type but with a special post-processing for the looked-up value: It
5384 parses it into alternatives according to `|' chars and then only one
5385 particular alternative is chosen randomly (this is an essential
5386 functionality needed for balancing between backend-servers when using
5387 Apache as a Reverse Proxy. The looked up value here is a list of
5388 servers). Second, `int' with the built-in maps named `tolower' and
5389 `toupper' which can be used to map URL parts to a fixed case (this is an
5390 essential feature to fix the case of server names when doing mass
5391 virtual-hosting with the help of mod_rewrite instead of using
5392 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
5393 Jay Soffian <jay@cimedia.com>] PR#1631
5395 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
5396 This directive lets Apache adjust the URL in Location-headers on HTTP
5397 redirect responses sent by the remote server. This way the virtually
5398 mapped area is no longer left on redirects and thus by-passed which is
5399 especially essential when running Apache as a reverse proxy.
5400 [Ralf S. Engelschall]
5402 *) Hide Proxy-Authorization from CGI/SSI/etc just like Authorization is
5403 hidden. [Alvaro Martinez Echevarria]
5405 *) Apache will, when started with the -X (single process) debugging flag,
5406 honor the SIGINT or SIGQUIT signals again now. This capability got lost
5407 a while ago during OS/2 signal handling changes.
5409 *) [PORT] Work around the fact that NeXT runs on more than the
5410 m68k chips in mod_status [Scott Anguish and Timothy Luoma

5417 *) Use SA_RESETHAND or SA_ONESHOT when installing the coredump handlers.
5418 In particular the handlers could trigger themselves into an infinite
5419 loop if RLimitMem was used with a small amount of memory -- too small
5420 for the signal stack frame to be set up. [Dean Gaudet]

5431 *) API: As Ken suggested the check_cmd_context() function and related
5432 defines are non-static now so modules can use 'em. [Martin Kraemer]
5434 *) mod_info would occasionally produce an unpaired <tt> in its
5435 output. Fixed. [Martin Kraemer]
5437 *) By default AIX binds a process (and it's children) to a single
5438 processor. httpd children now unbind themselves from that cpu
5439 and re-bind to one selected at random via bindprocessor()
5442 *) Linux 2.0 and above implement RLIMIT_AS, RLIMIT_DATA has almost no
5443 effect. Work around it by using RLIMIT_AS for the RLimitMEM
5444 directive. [Enrik Berkhan <enrik@inka.de>] PR#1816
5446 *) mod_mime_magic error message should indicate the filename when
5447 reads fail. ["M.D.Parker" <mdpc@netcom.com>] PR#1827
5449 *) Previously Apache would permit </Files> to end <FilesMatch> (and
5450 similary for Location and Directory), now this is diagnosed as an
5451 error. Improve error messages for mismatched sections (<Files>,
5452 <FilesMatch>, <Directory>, <DirectoryMatch>, ...).
5453 [Dean Gaudet, Martin Kraemer]
5455 *) <Files> is not permitted within <Location> (because of the
5456 semantic ordering). [Dean Gaudet] PR#379
5458 *) <Files> with wildcards was broken by the change in wildcard
5459 semantics (* does not match /). To fix this, <Files> now
5460 apply only to the basename of the request filename. This
5461 fixes some other inconsistencies in <Files> semantics
5462 (such as <Files a*b> not working). [Dean Gaudet] PR#1817
5464 *) Removed bogus "dist.tar" target from Makefile.tmpl and make sure
5465 backup files are removed on "clean" target [Ralf S. Engelschall]
5467 *) PORT: Add -lm to LIBS for HPUX. [Dean Gaudet] PR#1639
5469 *) Various errors from select() and accept() in child_main() would
5470 result in an infinite loop. It seems these two tickle kernel
5471 or library bugs occasionally, and result in log spammage and
5472 a generally bad scene. Now the child exits immediately,
5473 which seems to be a good workaround.

5487 Changes with Apache 1.3b5
5489 *) Source file dependencies in Makefile.tmpl files throughout the

5493 *) Preserve the content encoding given by the AddEncoding directive
5494 when the client doesn't otherwise specify an encoding.

5497 *) Sort out problems with canonical filename handling happening too late.
5498 [Dean Gaudet, Ben Laurie]
5500 Changes with Apache 1.3b4
5502 *) The module structure was modified to include a *dynamic_load_handle
5503 in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
5504 has been bumped accordingly. [Paul Sutton]
5506 *) All BrowserMatch directives mentioned in
5507 htdocs/manual/known_client_problems.html are in the default
5508 configuration files. [Lars Eilebrecht]
5510 *) MiNT port update. [Jan Paul Schmidt]
5512 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
5513 equivalent, similarly for x-compress and compress. Apache
5514 now ignores a leading x- when comparing encodings. It also
5515 preserves the encoding the client requests (for example if
5516 it requests x-gzip, then Apache will respond with x-gzip
5517 in the Content-Encoding header).
5518 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1772
5520 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
5522 *) Added mod_so module to support dynamic loading of modules on Unix
5523 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
5524 instead of AddModule in Configuration to build shared modules
5525 [Sameer Parekh, Paul Sutton]
5527 *) Minor cleanups to r->finfo handling in some modules.
5530 *) Abstract read()/write() to ap_read()/ap_write().
5531 Makes it easier to add other types of IO code such as SFIO.
5534 *) API: Generalize default_port manipulations to make support of
5535 different protocols easier. [Ben Laurie, Randy Terbush]
5537 *) There are many cases where users do not want Apache to form
5538 self-referential urls using the "canonical" ServerName and Port.
5539 The new UseCanonicalName directive (default on), if set to off
5540 will cause Apache to use the client-supplied hostname and port.
5541 API: Part of this change required a change to the construct_url()
5542 prototype; and the addition of get_server_name() and
5544 [Michael Douglass <mikedoug@texas.net>, Dean Gaudet]
5545 PR#315, 459, 485, 1433
5547 *) Yet another rearrangement of the source tree.. now all the common
5548 header files are in the src/include directory. The -Imain -Iap
5549 references in Makefiles have been changed to the simpler -Iinclude
5550 instead. In addition to simplifying the build a little bit, this
5551 also makes it clear when a module is referencing something in a
5552 other than kosher manner (e.g., the proxy including mod_mime.h).
5553 Module-private header files (the proxy, mod_mime, the regex library,
5554 and mod_rewrite) have not been moved to src/include; nor have
5555 the OS-abstraction files. [Ken Coar]
5557 *) Fix a bug where r->hostname didn't have the :port stripped
5558 from it. [Dean Gaudet]
5560 *) Tweaked the headers_out table size, and the subprocess_env
5561 table size guess in rename_original_environment(). Added
5562 MAKE_TABLE_PROFILE which can help discover make_table()
5563 calls that use too small an initial guess, see alloc.c.
5566 *) Options and AllowOverride weren't properly merging in the main
5567 server setting inside vhosts (only an issue when you have no
5568 <Directory> or other section containing an Options that affects
5569 a request). Options +foo or -foo in the main_server wouldn't
5570 affect the main_server's lookup defaults. [Dean Gaudet]
5572 *) Variable 'cwd' was being used pointlessly before being set.
5575 *) r->allowed handling cleaned up in the standard modules.
5578 *) Some case-sensitivity issues cleaned up to be consistent with
5579 RFC2068. [Dean Gaudet]
5581 *) SIGURG doesn't exist everywhere.
5582 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
5584 *) mod_unique_id was erroneously generating a second unique id when
5585 an internal redirect occured. Such redirects occur, for example,
5586 when processing a DirectoryIndex match. [Dean Gaudet]
5588 *) API: table_add, table_merge, and table_set include implicit pstrdup()
5589 of the key and value. But in many cases this is not required
5590 because the key/value is a constant, or the value has been built
5591 by pstrcat() or other similar means. New routines table_addn,
5592 table_mergen, and table_setn have been added to the API, these
5593 routines do not pstrdup() their arguments. The core code and
5594 standard modules were changed to take advantage of these routines.
5595 The resulting server is up to 20% faster in some situations.
5597 Note that it is easy to get code subtly wrong if you pass a key/value
5598 which is in a pool other than the pool of the table. The only
5599 safe thing to do is to pass key/values which are in the pool of
5600 the table, or in one of the ancestors of the pool of the table.
5601 i.e. if the table is part of a subrequest, a value from the main
5602 request's pool is OK since the subrequest pool is a sub_pool of the
5603 main request's pool (and therefore has a lifespan at most as long as
5604 the main pool). There is debugging code which can detect improper
5605 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
5606 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
5608 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
5609 which don't exist on disk more gracefully; handles vhosts properly.
5610 Update documentation to reflect the code -- if there's no
5611 MimeMagicFile directive then the module is not enabled.
5614 *) PORT: Some older *nix dialects cannot automatically start scripts
5615 which begin with a #! interpreter line (the shell starts the scripts
5616 appropriately on these platforms). Apache now supports starting of
5617 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
5618 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
5621 *) API: "typedef array_header table" removed from alloc.h, folks should
5622 have been writing to use table as if it were an opaque type, but even
5623 some standard modules got this wrong. By changing the definition
5624 to "typedef struct table table" module authors will receive compile
5625 time warnings that they're doing the wrong thing. This change
5626 facilitates future changes with more sophisticated table
5627 structures. Specifically, module authors should be using table_elts()
5628 to get access to an array_header * for the table. [Dean Gaudet]
5630 *) API: Renamed new_connection() to avoid namespace collision with LDAP
5631 library routines. [Ken Coar, Rasmus Lerdorf]
5633 *) WIN32: mod_speling is now available on the Win32 platform.
5636 *) For clarity the following compile time definition was changed:
5638 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
5640 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
5641 and not be a general notice that the OS has mmap(). Now the
5642 HAVE_MMAP/SHMGET #defines strictly are informational that the
5643 OS has that method of shared memory; the type to use for
5644 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
5645 and USE_SHMGET_SCOREBOARD). This allows outside modules to
5646 determine if shared memory is available and allows Apache
5647 to determine the best method to use for the scoreboard.
5650 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
5651 as do various earlier versions. It should be safe on all versions.
5652 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
5653 the slack code. A few other cleanups for Unixware.

5656 *) PORT: A/UX can handle single-listen accepts without mutex
5657 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
5659 *) When die() happens we need to eat any request body if one exists.
5660 Otherwise we can't continue with a keepalive session. This shows up
5661 as a POST problem with MSIE 4.0, typically against pages which are
5662 authenticated. [Roy Fielding] PR#1399
5664 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
5665 header will be passed to CGIs. This is generally a security hole, so
5666 it's not a default. [Marc Slemko] PR#549
5668 *) Fix Y2K problem with date printing in suexec log.

5671 *) WIN32 deserves a pid file. [Ben Hyde]
5673 *) suexec errors now include the errno/description. [Marc Slemko] PR#1543
5675 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
5676 The choice of flock vs. fcntl was made based on timings which showed that
5677 even on non-NFS, non-exported filesystems fcntl() was an order of
5678 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
5679 that single socket users will see no difference. [Dean Gaudet] PR#467
5681 *) "File does not exist" error message was erroneously including the
5682 errno. [Marc Slemko]
5684 *) Improve the warning message generated when a client drops the
5685 connection (hits stop button, etc.) during a send. [Roy Fielding]
5687 *) Defining GPROF will disable profiling in the parent and enable it
5688 in the children. If you're profiling under Linux this is pretty much
5689 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
5691 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.

5701 *) Some const declarations in mod_imap.c that were added for debugging
5702 purposes caused some compilers heartburn without adding any
5703 significant value, so they've been removed. [Ken Coar]
5705 *) The src/main/*.h header files have had #ifndef wrappers added to
5706 insulate them against duplicate calls if they get included through
5707 multiple paths (e.g., in .c files as well as other .h files).
5710 *) The libap routines now have a header file for their prototypes,
5711 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
5713 *) mod_autoindex with a plaintext header file would emit the <PRE>
5714 start-tag before the HTML preamble, rather than after the preamble
5715 but before the header file contents. [John Van Essen <jve@gamers.org>]
5718 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
5719 only an issue on systems without a MAXDNAME define or where
5720 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
5722 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
5723 is used to read various types of files such as htaccess and
5724 htpasswd files. [Marc Slemko]
5726 *) SECURITY: Ensure that the buffer returned by ht_time is always
5727 properly null terminated. [Marc Slemko]
5729 *) The "Connection" header could be sent back with multiple "close"
5730 tokens. Not an error, but a waste.
5731 [Ronald.Tschalaer@psi.ch] PR#1683
5733 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
5734 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
5736 *) "basic" auth needs a case-insensitive comparison.
5737 [Ronald.Tschalaer@psi.ch] PR#1666
5739 *) For maximum portability, the environment passed to CGIs should
5740 only contain variables whose names match the regex
5741 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
5742 underscores over any character outside the regex. This
5743 affects HTTP_* variables, in a way that should be backward
5744 compatible for all the standard headers; and affects variables
5745 set with SetEnv/BrowserMatch and similar directives.
5748 *) mod_speling returned incorrect HREF's when an ambigous match

5836 bogus chunked output. (Typically this will show up as problems
5837 with Internet Explorer 4.0 reading a page, but other browsers
5838 having no problem.) [Dean Gaudet]
5840 *) Create LARGE_WRITE_THRESHOLD define which determines how many
5841 bytes have to be supplied to bwrite() before it will consider
5842 doing a writev() to assemble multiple buffers in one system
5843 call. This is critical for modules such as mod_include,
5844 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
5845 strings in some cases. The result would be extra effort
5846 setting up writev(), and in many cases extra effort building
5847 chunks. The default is 31, it can be overriden at compile
5850 *) Move the gid switching code into the child so that log files
5851 and pid files are opened with the root gid.

5855 instead of counting control characters.
5856 [Jim Patterson <Jim.Patterson@Cognos.COM>] PR#1340
5858 *) ap_snprintf() moved from main/util_snprintf.c to ap/ap_snprintf.c
5859 so the functionality is available to applications other than the
5860 server itself (like the src/support tools). [Ken Coar]
5862 *) ap_slack() moved out of main/util.c into ap/ap_slack.c as part of
5863 the libap consolidation work. [Ken Coar]
5865 *) ap_snprintf() with a len of 0 behaved like sprintf(). This is not
5866 useful, and isn't what the standards require. Now it returns 0
5867 and writes nothing. [Dean Gaudet]

5875 *) mod_autoindex had an fread() without checking the result code.
5876 It also wouldn't handle "AddIconByType (TXT,/icons/text.gif text/*"

5957 This turns out to be a bug in Winsock - select() doesn't always
5958 return the correct status. [Ben Laurie]
5960 *) Directives owned by http_core can now use the new check_cmd_context()
5961 routine to ensure that they're not being used within a container
5962 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
5964 *) PORT: Recent changes made it necessary to add explicit prototype
5965 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
5967 *) It was necessary to distinguish between resources which are
5968 allocated in the parent, for cleanup in the parent, and resources
5969 which are allocated in each child, for cleanup in each child.
5970 A new pool was created which is passed to the module child_init
5971 and child_exit functions; modules are free to register per-child
5972 cleanups there. This fixes a bug with reliable piped logs.
5975 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
5976 unless it was also doing FancyIndexes, but it displayed the
5977 HeaderName file at the top under all circumstances. It now shows
5978 the ReadmeName file for simple indices, too, as it should.
5981 *) http_core was mmap()ing even in cases where it wasn't going to
5982 read the file. [Ben Hyde <bhyde@gensym.com>]
5984 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
5985 Now the rewriting engine (the heart of mod_rewrite) is organized more
5986 straight-forward, first time well documented and reduced to the really
5987 essential parts. All redundant cases were stripped off and processing now
5988 is the same for both per-server and per-directory context with only a
5989 minimum difference (the prefix stripping in per-dir context). As a
5990 side-effect some subtle restrictions and two recently discovered problems
5991 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
5992 context and restrictions on the substitution URL on redirects.
5993 Additionally some minor source cleanups were done.

6150 *) TestCompile was not passing $LIBS [Dean Gaudet]
6152 *) Makefile.tmpl was not using $CFLAGS in the link phase.
6155 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
6156 rudimentary memory debugger which can be used on live servers with
6157 low impact -- it sets all allocated and freed memory bytes to 0xa5.
6158 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
6159 and free() for each object. This is far more expensive and should
6160 only be used for testing with tools such as Electric Fence and
6161 Purify. See main/alloc.c for more details. [Dean Gaudet]
6163 *) Configure uses a sh trap and didn't set its exitcode properly.
6164 [Dean Gaudet] PR#1159
6166 *) Yet another vhost revamp. Add the NameVirtualHost directive which
6167 explicitly lists the ip:port pairs that are to be used for name-vhosts.
6168 From a given ip:port, regardless what the Host: header is, you can
6169 only reach the vhosts defined on that ip:port. The precedence of
6170 vhosts was reversed to match other precedences in the config --
6171 the earlier vhosts override the later vhosts. All vhost matching was
6172 moved into http_vhost.[ch]. [Dean Gaudet]
6174 *) ap_inline can be used to force inlining. GNUC __attribute__() can
6175 be used for whatever reason is appropriate (i.e. format() warnings
6176 for printf style functions). Both are enabled only with
6177 gcc >= 2.7.x (so that we have fewer support issues with older
6178 versions). [Dean Gaudet]
6180 *) Fix support for Proxy Authentication (we were testing the response
6181 status too early). [Marc Slemko]
6183 *) CoreDumpDirectory directive directs where the core file is
6184 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are

6188 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
6190 *) When booting, apache will now detach itself from stdin, stdout,
6191 and stderr. stderr will not be detached until after the config
6192 files have been read so you will be able to see initial error
6193 messages. After that all errors are logged in the error_log.
6194 This makes it more convenient to start apache via rsh, ssh,
6195 or crontabs. [Dean Gaudet] PR#523
6197 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
6198 Also removed the auto-generated link to www.apache.org that was the
6199 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
6201 *) send_fb would not detect aborted connections in some situations.
6204 *) mod_include would use uninitialized data when parsing certain

6207 *) mod_imap should only handle GET methods. [Jay Bloodworth]
6209 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
6211 *) mod_autoindex improperly counted &escapes; as more than one
6212 character in the description. It also improperly truncated
6213 descriptions that were exactly the maximum length.
6216 *) RedirectMatch was not properly escaping the result (PR#1155). Also
6217 "RedirectMatch /advertiser/(.*) $1" is now permitted.
6220 *) mod_include now uses symbolic names to check for request success
6221 and return HTTP errors, and correctly handles all types of
6222 redirections (previously it only did temporary redirect correctly).
6223 [Ken Coar, Roy Fielding]
6225 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
6226 r->filename. Since those two are meant to be in sync with each other

6239 *) Fixed error in proxy_util.c when looping through multiple host IP
6240 addresses. [Lars Eilebrecht] PR#974
6242 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
6243 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
6244 bytes before writing, but it will never split a log entry across a
6245 buffer boundary. [Dean Gaudet]
6247 *) API: the short_score record has been split into two pieces, one which
6248 the parent writes on, and one which the child writes on. As part of
6249 this change the get_scoreboard_info() function was removed, and
6250 scoreboard_image was exported. This change fixes a race condition
6251 in file based scoreboard systems, and speeds up changes involving the
6252 scoreboard in earlier 1.3 development. [Dean Gaudet]
6254 *) API: New register_other_child() API (see http_main.h) which allows
6255 modules to register children with the parent for maintenance. It
6256 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
6258 *) API: New piped_log API (see http_log.h) which implements piped logs,
6259 and will use register_other_child to implement reliable piped logs
6260 when it is available. The reliable piped logs part can be disabled
6261 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
6262 logs is only available on Unix. [Dean Gaudet]
6264 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
6265 meets_conditions(). This allows conditional HTTP selection to be
6266 handled separately from the storing of the header fields, and provides
6267 the ability for CGIs to set their own ETags for conditional checking.

6275 *) New module, "mod_speling", which can help find files even when
6276 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
6278 *) API: New function child_terminate() triggers the child process to
6279 exit, while allowing the child finish what it needs to for the
6280 current request first.
6281 [Doug MacEachern, Alexei Kosut]
6283 *) Windows now defaults to using full status reports with mod_status.

6286 *) *Really* disable all mod_rewrite operations if the engine is off.
6287 Some things (like RewriteMaps) were checked/performed even if they
6288 weren't supposed to be. [Ken Coar] PR #991
6290 *) Implement a new timer scheme which eliminates the need to call alarm() all
6291 the time. Instead a counter in the scoreboard for each child is used to
6292 show when the child has made forward progress. The parent samples this
6293 counter every scoreboard maintenance cycle, and issues SIGALRM if no
6294 progress has been made in the timeout period. This reduces the static
6295 request best-case syscall count to 22 from 29. This scheme is only
6296 used by systems with memory-based scoreboards. [Dean Gaudet]
6298 *) The proxy now properly handles CONNECT requests which are sent
6299 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
6301 *) A script called apachectl has been added to the support
6302 directory. This script allows you to do things such as
6303 "apachectl start" and "apachectl restart" from the command
6306 *) Modules and core routines are now put into libraries, which
6307 simplifies the link line tremendously (among other advantages).
6310 *) Some of the MD5 names defined in Apache have been renamed to have
6311 an `ap_' prefix to avoid conflicts with routines supplied by
6312 external libraries. [Ken Coar]
6314 *) Removal of mod_auth_msql.c from the distribution. There are many
6315 other options for databases today. Rather than offer one option,
6316 offer none at this time. mod_auth_msql and other SQL database
6317 authentication modules can be found at the Apache Module Registry.
6318 http://modules.apache.org/ It would be nice to offer a generic
6319 mod_auth_sql option in the near future.
6321 *) PORT: BeOS support added [Alexei Kosut]
6323 *) Configure no longer accepts the -make option, since it creates
6324 Makefile on the fly based on Makefile.tmpl and Configuration.
6326 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
6327 of forcibly killing off all its processes and exiting without
6328 cleaning up. [Alexei Kosut]
6330 *) API: A new field in the request_rec, r->mtime, has been added to
6331 avoid gratuitous parsing of date strings. It is intended to hold
6332 the last-modified date of the resource (if applicable). An
6333 update_mtime() routine has also been added to advance it if
6334 appropriate. [Roy Fielding, Ken Coar]
6336 *) SECURITY: If a htaccess file can not be read due to bad permissions,
6337 deny access to the directory with a HTTP_FORBIDDEN. The previous
6338 behavior was to ignore the htaccess file if it could not be read.
6339 This change may make some setups with unreadable htaccess files
6340 stop working. [Marc Slemko] PR#817
6342 *) Add aplog_error() providing a mechanism to define levels of
6343 verbosity to the server error logging. This addition also provides
6344 the ability to log errors using syslogd. Error logging is configurable
6345 on a per-server basis using the LogLevel directive. Conversion
6346 of log_*() in progress. [Randy Terbush]
6348 *) Further enhance aplog_error() to not log filename, line number, and
6349 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]

6361 configured and running" entry in the error_log. Also build an
6362 object file at link-time that contains the current time
6363 (SERVER_BUILT global const char[]), and include that in the
6366 *) Set r->headers_out when sending responses from the proxy.
6367 This fixes things such as the logging of headers sent from
6368 the proxy. [Marc Slemko] PR#659
6370 *) support/httpd_monitor is no longer distributed because the
6371 scoreboard should not be file based if at all possible. Use
6372 mod_status to see current server snapshot.
6374 *) (set_file_slot): New function, allowing auth directives to be
6375 independent of the server root, so the server documents can be
6376 moved to a different directory or machine more easily.
6377 [David J. MacKenzie]
6379 *) If no TransferLog is given explicitly, decline
6380 to log. This supports coexistence with other logging modules,
6381 such as the custom one that UUNET uses. [David J. MacKenzie]
6383 *) Check for titles in server-parsed HTML files.
6384 Ignore leading newlines and returns in titles. The old behavior
6385 of replacing a newline after <title> with a space causes the
6386 title to be misaligned in the listing. [David J. MacKenzie]
6388 *) Change mod_cern_meta to be configurable on a per-directory basis.
6389 [David J. MacKenzie]
6391 *) Add 'Include' directive to allow inclusion of configuration
6392 files within configuration files. [Randy Terbush]
6394 *) Proxy errors on connect() are logged to the error_log (nothing
6395 new); now they include the IP address and port that failed
6396 (*that's* new). [Ken Coar, Marc Slemko] PR#352
6398 *) Various architectures now define USE_MMAP_FILES which causes
6399 the server to use mmap() for static files. There are two
6400 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
6401 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
6402 number of bytes written in one cycle from a single mmap()d object,
6403 default 32768). [Dean Gaudet]
6405 *) API: Added post_read_request API phase which is run right after reading
6406 the request from a client, or right after an internal redirect. It is
6407 useful for modules setting environment variables that depend only on
6408 the headers/contents of the request. It does not run during subrequests
6409 because subrequests inherit pretty much everything from the main
6410 request. [Dean Gaudet]
6412 *) Added mod_unique_id which is used to generate a unique identifier for
6413 each hit, available in the environment variable UNIQUE_ID.
6416 *) init_modules is now called after the error logs have been opened. This
6417 allows modules to emit information messages into the error logs.
6420 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
6421 information for case where proxy module is not available. [Marc Slemko]
6423 *) PORT: Apache has need for mutexes to serialize its children around
6424 accept. In prior versions either fcntl file locking or flock file
6425 locking were used. The method is chosen by the definition of
6426 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
6427 and FLOCK for flock(). New options have been added:
6428 - SYSVSEM to use System V style semaphores
6429 - PTHREAD to use POSIX threads (appears to work on Solaris only)
6430 - USLOCK to use IRIX uslock
6431 Based on timing various techniques, the following changes were made
6433 - Linux 2.x uses flock instead of fcntl
6434 - Solaris 2.x uses pthreads
6435 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
6436 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
6437 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
6438 Martijn Koster <m.koster@pobox.com>]
6440 *) PORT: The semantics of accept/select make it very desirable to use
6441 mutexes to serialize accept when multiple Listens are in use. But
6442 in the case where only a single socket is open it is sometimes
6443 redundant to serialize accept(). Not all unixes do a good job with
6444 potentially dozens of children blocked on accept() on the same
6445 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
6446 the server will avoid serialization when listening on only one socket,
6447 and use serialization when listening on multiple sockets.
6448 [Dean Gaudet] PR#467
6450 *) Configure changes: TestLib replaced by TestCompile, which has
6451 some additional capability (such as doing a sanity check of
6452 the compiler and flags selected); the version of Solaris is now
6453 available via the #define value of SOLARIS2; IRIX n32bit libs
6454 now supported and selectable by new Configuration Rule: IRIXN32;
6455 We no longer default to -O2 optimization. [Jim Jagielski]
6457 *) Updated Configure: Configuration now uses AddModule to specify
6458 module source or binary file location, relative to src directory.
6459 Modules can be dropped into modules/extra, or in their own
6460 directory, and modules can come with a Makefile or Configure can
6461 create one. Modules can add compiler or library information to
6462 generated Makefiles. [Paul Sutton]
6464 *) Source core re-organisation: distributed modules are now in
6465 modules/standard. All other source code is in main. OS-specific
6466 code is in os/{unix,emx,win32} directories. [Paul Sutton]
6468 *) mod_browser has been removed, since it's replaced by mod_setenvif.
6471 *) Fix another long-standing bug in sub_req_lookup_file where it would
6472 happily skip past access checks on subdirectories looked up with
6473 relative paths. (It's used by mod_dir, mod_negotiation,
6474 and mod_include.) [Dean Gaudet]
6476 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
6477 N is the number of <Directory> sections, and M is the number of
6478 components in the filename of an object.
6480 To achieve this optimization the following config changes were made:
6481 - Wildcards (* and ?, not the regex forms) in <Directory>s,
6482 <Files>s, and <Location>s now treat a slash as a special
6483 character. For example "/home/*/public_html" previously would
6484 match "/home/a/andrew/public_html", now it only matches things
6485 like "/home/bob/public_html". This mimics /bin/sh behaviour.
6486 - It's possible now to use [] wildcarding in <Directory>, <Files>
6488 - Regex <Directory>s are applied after all non-regex <Directory>s.
6492 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
6493 and corrupted paths. [Dean Gaudet]
6495 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
6496 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
6497 be accessed now via backreferences $1..$9 in RewriteConds test-against
6498 strings in addition to RewriteRules subst string. Second the grouped
6499 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
6500 via backreferences %1..%9 both in following RewriteCond test-against
6501 strings and RewriteRules subst string. This provides maximum flexibility
6502 through the use of backreferences.
6503 Additionally the rewriting engine was cleaned up by putting common
6504 code to the new expand_backrefs_inbuffer() function.
6505 [Ralf S. Engelschall]
6507 *) When merging the main server's <Directory> and <Location> sections into
6508 a vhost, put the main server's first and the vhost's second. Otherwise
6509 the vhost can't override the main server. [Dean Gaudet] PR#717
6511 *) The <Directory> code would merge and re-merge the same section after
6512 a match was found, possibly causing problems with some modules.
6515 *) ip-based vhosts are stored and queried using a hashing function, which
6516 has been shown to improve performance on servers with many ip-vhosts.
6517 Some other changes had to be made to accommodate this:
6518 - the * address for vhosts now behaves like _default_
6519 - the matching process now is:
6520 - match an ip-vhost directly via hash (possibly matches main
6522 - if that fails, just pretend it matched the main server
6523 - if so far only the main server has been matched, perform
6524 name-based lookups (ServerName, ServerAlias, ServerPath)
6525 *only on name-based vhosts*
6526 - if they fail, look for _default_ vhosts
6527 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
6529 *) dbmmanage overhaul:
6530 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
6531 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
6532 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
6533 - provide better seed for rand
6534 - prompt for password as per getpass(3) (turn off echo, read from
6536 - use "newstyle" crypt based on $Config{osname} ($^O)
6537 - will not add a user if already in database, use new `update' command
6539 - added `check' command to check a users' password
6540 - added `import' command to convert existing password text-files or
6541 dbm files exported with `view'
6542 - more descriptive usage, general cleanup, 'use strict' clean, etc.
6545 *) Added psocket() which is a pool form of socket(), various places within
6546 the proxy weren't properly blocking alarms while registering the cleanup
6547 for its sockets. bclose() now uses pclose() and pclosesocket(). There
6548 was a bug where the client socket was being close()d twice due a still
6549 registered cleanup. [Dean Gaudet]
6551 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
6554 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
6555 [Jason Venner <jason@idiom.com>] PR#667
6557 *) Enable ``=""'' for RewriteCond directives to match against
6558 the empty string. This is the preferred way instead of ``^$''.
6559 [Ralf S. Engelschall]
6561 *) Fixed an infinite loop in mod_imap for references above the server root
6562 [Dean Gaudet] PR#748
6564 *) mod_proxy now has a ReceiveBufferSize directive, similar to
6565 SendBufferSize, so that the TCP window can be set appropriately
6566 for LFNs. [Phillip A. Prindeville]
6568 *) mod_browser has been replaced by the more general mod_setenvif
6569 (courtesy of Paul Sutton). BrowserMatch* directives are still
6570 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
6571 UnSetEnvIfZero directives. [Ken Coar]
6573 *) "HostnameLookups double" forces double-reverse DNS to succeed in
6574 order for remote_host to be set (for logging, or for the env var
6575 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
6578 *) mod_access overhaul:
6579 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
6580 and cidr syntax (i.e. 10.1.0.0/16). PR#762
6581 - Critical path was sped up by pre-computing a few things at config time.
6582 - The undocumented syntax "allow user-agents" was removed,
6583 the replacement is "allow from env=foobar" combined with mod_browser.
6584 - When used with hostnames it now forces a double-reverse lookup
6585 no matter what the directory settings are. This double-reverse
6586 doesn't affect any of the other routines that use the remote
6587 hostname. In particular it's still passed to CGIs and the log
6588 without the double-reverse check. Related PR#860.
6591 *) When a large bwrite() occurs (larger than the internal buffer size),
6592 while there is already something in the buffer, apache will combine
6593 the large write and the buffer into a single writev(). (This is
6594 in anticipation of using mmap() for reading files.)
6597 *) In obscure cases where a partial socket write occurred while chunking,
6598 Apache would omit the chunk header/footer on the next block. Cleaned
6599 up other bugs/inconsistencies in error conditions in buff.c. Fixed
6600 a bug where a long pause in DNS lookups could cause the last packet
6601 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
6603 *) API: Added child_exit function to module structure. This is called
6604 once per "heavy-weight process" just before a server child exit()'s
6605 e.g. when max_requests_per_child is reached, etc.
6606 [Doug MacEachern, Dean Gaudet]
6608 *) mod_include cleanup showed that handle_else was being used to handle
6609 endif. It didn't cause problems, but it was cleaned up too.
6612 *) mod_cern_meta would attempt to find meta files for the directory itself
6613 in some cases, but not in others. It now avoids it in all cases.
6616 *) mod_mime_magic would core dump if there was a decompression error.
6617 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
6619 *) PORT: some variants of DGUX require -lsocket -lnsl
6620 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
6622 *) mod_autoindex now allows sorting of FancyIndexed directory listings
6623 by the various fields (name, size, et cetera), either in ascending
6624 or descending order. Just click on the column header. [Ken Coar]
6626 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
6627 CPUs like the Alpha. Apache still stores ints in pointers, but that's
6628 the relatively safe direction. [Dean Gaudet] PR#344
6630 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
6631 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
6633 *) child_main avoids an unneeded call to select() when there is only one
6634 listening socket. [Dean Gaudet]
6636 *) In the event that the server is starved for idle servers it will
6637 spawn 1, then 2, then 4, ..., then 32 servers each second,
6638 doubling each second. It'll also give a warning in the errorlog
6639 since the most common reason for this is a poor StartServers
6640 setting. The define MAX_SPAWN_RATE can be used to raise/lower
6641 the maximum. [Dean Gaudet]
6643 *) Apache now provides an effectively unbuffered connection for
6644 CGI scripts. This means that data will be sent to the client
6645 as soon as the CGI pauses or stops output; previously, Apache would
6646 buffer the output up to a fixed buffer size before sending, which
6647 could result in the user viewing an empty page until the CGI finished
6648 or output a complete buffer. It is no longer necessary to use an
6649 "nph-" CGI to get unbuffered output. Given that most CGIs are written
6650 in a language that by default does buffering (e.g. perl) this
6651 shouldn't have a detrimental effect on performance.
6653 "nph-" CGIs, which formerly provided a direct socket to the client
6654 without any server post-processing, were not fully compatible with
6655 HTTP/1.1 or SSL support. As such they would have had to implement
6656 the transport details, such as encryption or chunking, in order
6657 to work properly in certain situations. Now, the only difference
6658 between nph and non-nph scripts is "non-parsed headers".
6659 [Dean Gaudet, Sameer Parekh, Roy Fielding]
6661 *) If a BUFF is switched from buffered to unbuffered reading the first
6662 bread() will return whatever remained in the buffer prior to the
6663 switch. [Dean Gaudet]
6665 Changes with Apache 1.3a1
6667 *) Added another Configure helper script: TestLib. It determines
6668 if a specified library exists. [Jim Jagielski]
6670 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
6671 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
6674 *) PORT: Some architectures use size_t for various lengths in network
6675 functions such as accept(), and getsockname(). The definition
6676 NET_SIZE_T is used to control this. [Dean Gaudet]
6678 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
6679 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
6680 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
6682 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
6683 [Igor N Kovalenko <infoh@mail.wplus.net>]
6685 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
6686 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
6687 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
6688 [Dean Gaudet] related PR#875
6690 *) API: Correct child_init() slot declaration from int to void, to
6691 match the init() declaration. Update mod_example to use the new
6694 *) added transport handle slot (t_handle) to the BUFF structure
6697 *) get_client_block() returns wrong length if policy is
6698 REQUEST_CHUNKED_DECHUNK.
6699 [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815
6701 *) Support the image map format of FrontPage. For example:

6703 ["Chris O'Byrne" <obyrne@iol.ie>] PR#807
6705 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
6706 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
6708 *) AddModuleInfo directive for mod_info which allows you to annotate
6709 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
6711 *) Added NoProxy directive to avoid using ProxyRemote for selected
6712 addresses. Added ProxyDomain directive to cause unqualified
6713 names to be qualified by redirection.
6714 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
6716 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
6717 header to the remote host in the proxy. [Sameer Parekh and
6720 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
6721 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
6722 URLs, fixed rewritelog(), fixed forced response code handling on
6723 redirects from within .htaccess files, disabled pipe locking under
6724 braindead SunOS 4.1.x, allow env variables to be set even on rules with
6725 no substitution, bugfixed situations where HostnameLookups is off, made
6726 mod_rewrite more thread-safe for NT port and fixed problem when creating
6727 an empty query string via "xxx?".
6728 This update also removes the copyright of Ralf S. Engelschall,
6729 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
6730 exclusively copyrighted by the Apache Group now. This happened because
6731 the author now has gifted mod_rewrite exclusively to the Apache Group and
6732 no longer maintains an external version.
6733 [Ralf S. Engelschall]
6735 *) API: Added child_init function to module structure. This is called
6736 once per "heavy-weight process" before any requests are handled.
6737 See http_config.h for more details. [Dean Gaudet]
6739 *) Anonymous_LogEmail was logging on each subrequest.
6740 [Dean Gaudet] PR#421, 868
6742 *) API: Added is_initial_req() which tests if the request being
6743 processed is the initial request, or a subrequest.
6746 *) Extended SSI (mod_include) now handles additional relops for
6747 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
6749 *) Configure fixed to correctly propagate user-selected options and
6750 settings (such as CC and OPTIM) to Makefiles other than
6751 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
6753 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
6754 directory indices to start with the contents of the HeaderName file
6755 if there is one. If there isn't one, the behaviour is unchanged.
6756 [Ken Coar, Roy Fielding, Andrey A. Chernov]
6758 *) WIN32: Modules can now be dynamically loaded DLLs using the
6759 LoadModule/LoadFile directives. Note that module DLLs must be
6760 compiled with the multithreaded DLL version of the runtime library.
6761 [Alexei Kosut and Ben Laurie]
6763 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
6764 This allows the admin to completely remove automatic indexing
6765 from the server, while still supporting the basic functions of
6766 trailing-slash redirects and DirectoryIndex files. Note that if
6767 you're carrying over an old Configuration file and you use directory
6768 indexing then you'll want to add:
6770 Module autoindex_module mod_autoindex.o
6772 before mod_dir in your Configuration. [Dean Gaudet]
6774 *) popendir/pclosedir created to properly protect directory scanning.
6775 [Dean Gaudet] PR#525
6777 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
6778 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
6779 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
6782 *) The AccessFileName directive can now take more than one filename.
6783 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
6785 *) The new mod_mime_magic can be used to "magically" determine the type
6786 of a file if the extension is unknown. Based on the unix file(1)
6787 command. [Ian Kluft <ikluft@cisco.com>]
6789 *) We now determine and display the time spent processing a
6790 request if desired. [Jim Jagielski]
6792 *) mod_status: PID field of "dead" child slots no longer displays
6793 main httpd process's PID. [Jim Jagielski]
6795 *) Makefile.nt added - to build all the bits from the command line:
6796 nmake -f Makefile.nt
6797 Doesn't yet work properly. [Ben Laurie]
6799 *) Default text of 404 error is now "Not Found" rather than the
6800 potentially misleading "File Not Found". [Ken Coar]
6802 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
6803 for the net if we require people that actually need this data to
6804 enable it. [Linus Torvalds]
6806 *) directory_walk() is an expensive function, keep a little more state to
6807 avoid needless string counting. Add two new functions make_dirstr_parent
6808 and make_dirstr_prefix which replace all existing uses of make_dirstr.
6809 The new functions are a little less general than make_dirstr, but
6810 work more efficiently (less memory, less string counting).
6813 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
6814 to LDFLAGS) to avoid complications with lex rules in make files.
6815 [Dean Gaudet] PR#372
6817 *) run_method optimized to avoid needless scanning over NULLs in the
6818 module list. [Dean Gaudet]
6820 *) Revamp of (unix) scoreboard management code such that it avoids
6821 unnecessary traversals of the scoreboard on each hit. This is
6822 particularly important for high volume sites with a large
6823 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
6824 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
6825 httpd.h. [Dean Gaudet]
6827 *) In configurations using multiple Listen statements it was possible for
6828 busy sockets to starve other sockets of service. [Dean Gaudet]
6830 *) Added hook so standalone_main can be replaced at compile time
6831 (define STANDALONE_MAIN)
6834 *) Lowest-level read/write functions in buff.c will be replaced with
6835 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
6836 compile time. The default sfio discipline will behave as apache
6837 would without sfio compiled in.
6840 *) Enhance UserDir directive (mod_userdir) to accept a list of
6841 usernames for the 'disable' keyword, and add 'enable user...' to
6842 selectively *en*able userdirs if they're globally disabled.
6845 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
6846 will work with Netscape dbm files. (dbmmanage will probably not
6847 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
6849 *) Add a ListenBacklog directive to control the backlog parameter
6850 passed to listen(). Also change the default to 511 from 512.
6853 *) API: A new handler response DONE which informs apache that the
6854 request has been handled and it can finish off quickly, similar to
6855 how it handles errors. [Rob Hartill]
6857 *) Turn off chunked encoding after sending terminating chunk/footer
6858 so that we can't do it twice by accident. [Roy Fielding]
6860 *) mod_expire also issues Cache-Control: max-age headers.
6863 *) API: Added kill_only_once option for free_proc_chain so that it won't
6864 aggressively try to kill off specific children. For fastcgi.
6865 [Stanley Gambarin <gambarin@OpenMarket.com>]
6867 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
6869 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
6870 When used together, these cause mod_dir to emit HEIGHT and WIDTH
6871 attributes in the FancyIndexing IMG tags. [Ken Coar]
6873 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
6875 *) PORT: Added Windows NT support
6876 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
6878 Changes with Apache 1.2.6
6880 *) mod_include when using XBitHack Full would send ETags in addition to
6881 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
6882 [Dean Gaudet] PR#1133
6884 *) SECURITY: When a client connects to a particular port/addr, and
6885 gives a Host: header ensure that the virtual host requested can
6886 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
6888 *) Support virtual hosts with wildcard port and/or multiple ports
6889 properly. [Ed Korthof <ed@organic.com>]
6891 *) Fixed some case-sensitivity issues according to RFC2068.
6894 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
6895 and mod_include.c. [Dean Gaudet]
6897 *) Variable 'cwd' was being used pointlessly before being set.
6900 *) SIGURG doesn't exist on all platforms.
6901 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
6903 *) When an error occurs during a POST, or other operation with a
6904 request body, the body has to be read from the net before allowing
6905 a keepalive session to continue. [Roy Fielding] PR#1399
6907 *) When an error occurs in fcntl() locking suggest the user look up
6908 the docs for LockFile. [Dean Gaudet]
6910 *) table_set() and table_unset() did not deal correctly with
6911 multiple occurrences of the same key. [Stephen Scheck
6912 <sscheck@infonex.net>, Ben Laurie] PR#1604
6914 *) send_fd_length() did not calculate total_bytes_sent properly in error
6915 cases. [Ben Reser <breser@regnow.com>] PR#1366
6917 *) r->connection->user was allocated in the wrong pool causing corruption
6918 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
6920 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
6921 Also removed the auto-generated link to www.apache.org that was the
6922 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
6924 *) Multiple "close" tokens may have been set in the "Connection"
6925 header, not an error, but a waste.
6926 [Ronald.Tschalaer@psi.ch] PR#1683
6928 *) "basic" and "digest" auth tokens should be tested case-insensitive.
6929 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
6931 *) It appears the "257th byte" bug (see
6932 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
6933 at the 256th byte as well. Fixed. [Dean Gaudet]
6935 *) mod_rewrite would not handle %3f properly in some situations.
6938 *) Apache could generate improperly chunked HTTP/1.1 responses when
6939 the bputc() or rputc() functions were used by modules (such as
6940 mod_include). [Dean Gaudet]
6942 *) #ifdef wrap a few #defines in httpd.h to make life easier on
6943 some ports. [Ralf Engelschall]
6945 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
6947 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
6949 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
6951 Changes with Apache 1.2.5
6953 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
6954 only an issue on systems without a MAXDNAME define or where
6955 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
6957 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
6960 *) Fix core dump in the ftp proxy when reading incorrectly formatted
6961 directory listings. [Marc Slemko]
6963 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
6966 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
6967 is used to read various types of files such as htaccess and
6968 htpasswd files. [Marc Slemko]
6970 *) SECURITY: Ensure that the buffer returned by ht_time is always
6971 properly null terminated. [Marc Slemko]
6973 *) SECURITY: General mod_include cleanup, including fixing several
6974 possible buffer overflows and a possible infinite loop. This cleanup
6975 was done against 1.3 code and then backported to 1.2, the result
6976 is a large difference (due to indentation cleanup in 1.3 code).
6977 Users interested in seeing a smaller set of relevant differences
6978 should consider comparing against src/modules/standard/mod_include.c
6979 from the 1.3b3 release. Non-indentation changes to mod_include
6980 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
6982 *) SECURITY: Numerous changes to mod_imap in a general cleanup
6983 including fixing a possible buffer overflow. This cleanup also
6984 was done with 1.3 code as a basis, see the the previous note
6985 about mod_include. [Dean Gaudet]
6987 *) SECURITY: If a htaccess file can not be read due to bad
6988 permissions, deny access to the directory with a HTTP_FORBIDDEN.
6989 The previous behavior was to ignore the htaccess file if it could not
6990 be read. This change may make some setups with unreadable
6991 htaccess files stop working. PR#817 [Marc Slemko]
6993 *) SECURITY: no2slash() was O(n^2) in the length of the input.
6994 Make it O(n). This inefficiency could be used to mount a denial
6995 of service attack against the Apache server. Thanks to
6996 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting
6999 *) mod_include used uninitialized data for some uses of && and ||.
7000 [Brian Slesinsky <bslesins@wired.com>] PR#1139
7002 *) mod_imap should decline all non-GET methods.
7003 [Jay Bloodworth <jay@pathways.sde.state.sc.us>]
7005 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7007 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7008 r->filename. Since those two are meant to be in sync with each other
7009 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
7011 *) mod_include did not properly handle all possible redirects from sub-
7012 requests. [Ken Coar]
7014 *) Inetd mode (which is buggy) uses timeouts without having setup the
7015 jmpbuffer. [Dean Gaudet] PR#1064
7017 *) Work around problem under Linux where a child will start looping
7018 reporting a select error over and over.
7019 [Rick Franchuk <rickf@transpect.net>] PR#1107
7021 Changes with Apache 1.2.4
7023 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
7024 always making requests with the full-URI instead of just the URI path.
7025 [Marc Slemko, Roy Fielding]
7027 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
7028 on this platform. [Marc Slemko]
7030 Changes with Apache 1.2.3
7032 *) The request to a remote proxy was mangled if it was generated as the
7033 result of a ProxyPass directive. URL schemes other than http:// were not
7034 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
7035 PR#812 [Lars Eilebrecht]
7037 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7038 information for case where proxy module is not available. [Marc Slemko]
7040 *) Force proxy to always respond as HTTP/1.0, which it was failing to
7041 do for errors and cached responses. [Roy Fielding]
7043 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
7045 Changes with Apache 1.2.2 [not released]
7047 *) Fixed another long-standing bug in sub_req_lookup_file where it would
7048 happily skip past access checks on subdirectories looked up with relative
7049 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
7052 *) Add lockfile name to error message printed out when
7053 USE_FLOCK_SERIALIZED_ACCEPT is defined.
7056 *) Enhanced the chunking and error handling inside the buffer functions.
7057 [Dean Gaudet, Roy Fielding]
7059 *) When merging the main server's <Directory> and <Location> sections into
7060 a vhost, put the main server's first and the vhost's second. Otherwise
7061 the vhost can't override the main server. [Dean Gaudet] PR#717
7063 *) The <Directory> code would merge and re-merge the same section after
7064 a match was found, possibly causing problems with some modules.
7067 *) Fixed an infinite loop in mod_imap for references above the server root.
7068 [Dean Gaudet] PR#748
7070 *) mod_include cleanup showed that handle_else was being used to handle
7071 endif. It didn't cause problems, but it was cleaned up too.
7074 *) Last official synchronization of mod_rewrite with author version (because
7075 mod_rewrite is now directly developed by the author at the Apache Group):
7076 o added diff between mod_rewrite 3.0.6+ and 3.0.9
7077 minus WIN32/NT stuff, but plus copyright removement.
7079 - workaround for detecting infinite rewriting loops
7080 - fixed setting of env vars when "-" is used as subst string
7081 - fixed forced response code on redirects (PR#777)
7082 - fixed cases where r->args is ""
7083 - kludge to disable locking on pipes under braindead SunOS
7084 - fix for rewritelog in cases where remote hostname is unknown
7085 - fixed totally damaged request_rec walk-back loop
7086 o remove static from local data and add static to global ones.
7087 o replaced ugly proxy finding stuff by simple
7088 find_linked_module("mod_proxy") call.
7089 o added missing negation char on rewritelog()
7090 o fixed a few comment typos
7091 [Ralf S. Engelschall]
7093 *) Anonymous_LogEmail was logging on each subrequest.
7094 [Dean Gaudet] PR#421, PR#868
7096 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7097 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7098 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
7099 Additionally mod_browser now triggers during translate_name to workaround
7100 a deficiency in the header_parse phase.
7101 [Dean Gaudet] PR#875
7103 *) get_client_block() returns wrong length if policy is
7104 REQUEST_CHUNKED_DECHUNK.
7105 [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815
7107 *) Properly treat <files> container like other containers in mod_info.
7108 [Marc Slemko] PR#848
7110 *) The proxy didn't treat the "Host:" keyword of the host header as case-
7111 insensitive. The proxy would corrupt the first line of a response from
7112 an HTTP/0.9 server. [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#813,814
7114 *) mod_include would log some bogus values occasionally.
7115 [Skip Montanaro <skip@calendar.com>, Marc Slemko] PR#797
7117 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
7118 under Solaris 2.x (up through 2.5.1). It has been fixed.
7119 [Dean Gaudet] PR#832
7121 *) API: In HTTP/1.1, whether or not a request message contains a body
7122 is independent of the request method and based solely on the presence
7123 of a Content-Length or Transfer-Encoding. Therefore, our default
7124 handlers need to be prepared to read a body even if they don't know
7125 what to do with it; otherwise, the body would be mistaken for the
7126 next request on a persistent connection. discard_request_body()
7127 has been added to take care of that. [Roy Fielding] PR#378
7129 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
7130 release version number, such that it always increases along the
7131 same lines as our source code branching. [Roy Fielding]
7133 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
7135 Changes with Apache 1.2.1
7137 *) SECURITY: Don't serve file system objects unless they are plain files,
7138 symlinks, or directories. This prevents local users from using pipes
7139 or named sockets to invoke programs for an extremely crude form of
7142 *) SECURITY: HeaderName and ReadmeName were settable in .htaccess and
7143 could contain "../" allowing a local user to "publish" any file on
7144 the system. No slashes are allowed now. [Dean Gaudet]
7146 *) SECURITY: It was possible to violate the symlink Options using mod_dir
7147 (headers, readmes, titles), mod_negotiation (type maps), or
7148 mod_cern_meta (meta files). [Dean Gaudet]
7150 *) SECURITY: Apache will refuse to run as "User root" unless
7151 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
7153 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
7154 if it contained a .htaccess disallowing symlinks. This is contrary
7155 to the rule that symlink permissions are tested with the symlink
7156 options of the parent directory. [Dean Gaudet] PR#353
7158 *) CONFIG: The LockFile directive can be used to place the serializing
7159 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
7160 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
7163 *) Request processing now retains state of whether or not the request
7164 body has been read, so that internal redirects and subrequests will
7165 not try to read it twice (and block). [Roy Fielding]
7167 *) Add a placeholder in modules/Makefile to avoid errors with certain
7168 makes. [Marc Slemko]
7170 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.
7171 [Dean Gaudet] PR#644
7173 *) mod_include was not properly changing the current directory.
7174 [Marc Slemko] PR#742
7176 *) Attempt to work around problems with third party libraries that do not
7177 handle high numbered descriptors (examples include bind, and
7178 solaris libc). On all systems apache attempts to keep all permanent
7179 descriptors above 15 (called the low slack line). Solaris users
7180 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
7181 which keeps all non-FILE * descriptors above 255. On all systems
7182 this should make supporting large numbers of vhosts with many open
7183 log files more feasible. If this causes trouble please report it,
7184 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
7185 [Dean Gaudet] various PRs
7187 *) Related to the last entry, network sockets are now opened before
7188 log files are opened. The only known case where this can cause
7189 problems is under Solaris with many virtualhosts and many Listen
7190 directives. But using -DHIGH_SLACK_LINE=256 described above will
7191 work around this problem. [Dean Gaudet]
7193 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
7196 *) Improved unix error response logging. [Marc Slemko]
7198 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
7199 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
7200 when a URL http://... was used in conjunction with a special
7201 redirect flag, e.g. R=permanent, the permanent status was lost.
7202 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>, Ralf S. Engelschall]
7204 *) If an object has multiple variants that are otherwise equal Apache
7205 would prefer the last listed variant rather than the first.
7208 *) "make clean" at the top level now removes *.o. [Dean Gaudet] PR#752
7210 *) mod_status dumps core in inetd mode. [Marc Slemko and Roy Fielding]
7213 *) pregsub had an off-by-1 in its error checking code. [Alexei Kosut]
7215 *) PORT: fix rlim_t problems with AIX 4.2. [Marc Slemko] PR#333
7217 *) PORT: Update UnixWare support for 2.1.2.
7218 [Lawrence Rosenman <ler@lerctr.org>] PR#511
7220 *) PORT: NonStop-UX [Joachim Schmitz <schmitz_joachim@tandem.com>] PR#327
7222 *) PORT: Update ConvexOS support for 11.5.
7223 [David DeSimone <fox@convex.com>] PR#399
7225 *) PORT: Support for DEC cc compiler under ULTRIX.
7226 ["P. Alejandro Lopez-Valencia" <alejolo@ideam.gov.co>] PR#388
7228 *) PORT: Support for Maxion/OS SVR4.2 Real Time Unix. [no name given] PR#383
7230 *) PORT: Workaround for AIX 3.x compiler bug in http_bprintf.c.
7231 [Marc Slemko] PR#725
7233 *) PORT: fix problem compiling http_bprintf.c with gcc under SCO
7234 [Marc Slemko] PR#695
7236 Changes with Apache 1.2
7238 Changes with Apache 1.2b11
7240 *) Fixed open timestamp fd in proxy_cache.c [Chuck Murcko]
7242 *) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
7243 [Doug MacEachern, Rob Hartill]
7245 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
7246 reading from one buffer and writing to another, at least until it has
7247 a custom timeout handler. [Roy Fielding and Petr Lampa]
7249 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
7250 apparently due to a mismatch between sigaction and setjmp.
7251 [Roy Fielding] PR#502
7253 *) Log correct status code if we timeout before receiving a request (408)
7254 or if we received a request-line that was too long to process (414).
7255 [Ed Korthof and Roy Fielding] PR#601
7257 *) Virtual hosts with the same ServerName, but on different ports, were
7258 not being selected properly. [Ed Korthof]
7260 *) Added code to return the requested IP address from proxy_host2addr()
7261 if gethostbyaddr() fails due to reverse DNS lookup problems. Original
7262 change submitted by Jozsef Hollosi <hollosi@sbcm.com>.
7263 [Chuck Murcko] PR#614
7265 *) If multiple requests on a single connection are used to retrieve
7266 data from different virtual hosts, the virtual host list would be
7267 scanned starting with the most recently used VH instead of the first,
7268 causing most virtual hosts to be ignored.
7269 [Paul Sutton and Martin Mares] PR#610
7271 *) The OS/2 handling of process group was broken by a porting patch for
7272 MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]
7274 *) Inherit virtual server port from main server if none (or "*") is
7275 given for VirtualHost. [Dean Gaudet] PR#576
7277 *) If the lookup for a DirectoryIndex name with content negotiation
7278 has found matching variants, but none are acceptable, return the
7279 negotiation result if there are no more DirectoryIndex names to lookup.
7280 [Petr Lampa and Roy Fielding]
7282 *) If a soft_timeout occurs after keepalive is set, then the main child
7283 loop would try to read another request even though the connection
7284 has been aborted. [Roy Fielding]
7286 *) Configure changes: Allow for whitespace at the start of a
7287 Module declaration. Also, be more understanding about the
7288 CC=/OPTIM= format in Configuration. Finally, fix compiler
7289 flags if using HP-UX's cc compiler. [Jim Jagielski]
7291 *) Subrequests and internal redirects now inherit the_request from the
7292 original request-line. [Roy Fielding]
7294 *) Test for error conditions before creating output header fields, since
7295 we don't want the error message to include those fields. Likewise,
7296 reset the content_language(s) and content_encoding of the response
7297 before generating or redirecting to an error message, since the new
7298 message will have its own Content-* definitions. [Dean Gaudet]
7300 *) Restored the semantics of headers_out (headers sent only with 200..299
7301 and 304 responses) and err_headers_out (headers sent with all responses).
7302 Avoid the overhead of copying tables if err_headers_out is empty
7303 (the usual case). [Roy Fielding]
7305 *) Fixed a couple places where a check for the default Content-Type was
7306 not properly checking both the value configured by the DefaultType
7307 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
7308 of DEFAULT_TYPE to match the documented default (text/plain).
7309 [Dean Gaudet] PR#506
7311 *) Escape the HTML-sensitive characters in the Request-URI that is
7312 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
7314 *) Properly initialize the flock structures used by the mutex locking
7315 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
7318 *) The method for determining PATH_INFO has been restored to the pre-1.2b
7319 (and NCSA httpd) definition wherein it was the extra path info beyond
7320 the CGI script filename. The environment variable FILEPATH_INFO has
7321 been removed, and instead we supply the original REQUEST_URI to any
7322 script that wants to be Apache-specific and needs the real URI path.
7323 This solves a problem with existing scripts that use extra path info
7324 in the ScriptAlias directive to pass options to the CGI script.
7327 *) The _default_ change in 1.2b10 will change the behaviour on configs
7328 that use multiple Listen statements for listening on multiple ports.
7329 But that change is necessary to make _default_ consistent with other
7330 forms of <VirtualHost>. It requires such configs to be modified
7331 to use <VirtualHost _default_:*>. The documentation has been
7332 updated. [Dean Gaudet] PR#530
7334 *) If an ErrorDocument CGI script is used to respond to an error
7335 generated by another CGI script which has already read the message
7336 body of the request, the server would block trying to read the
7337 message body again. [Rob Hartill]
7339 *) signal() replacement conflicted with a define on QNX (and potentially
7340 other platforms). Fixed. [Ben Laurie] PR#512
7342 Changes with Apache 1.2b10
7344 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
7345 to be configured via -D in Configuration. [Dean Gaudet] PR#449
7347 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
7349 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]
7351 *) In mod_proxy.c, check return values for proxy_host2addr() when reading
7352 config, in case the hostent struct returned is trash.
7353 [Chuck Murcko] PR #491
7355 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
7356 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
7358 Changes with Apache 1.2b9 [never announced]
7360 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
7361 changes and in anticipation of 1.2 final release. [Roy Fielding]
7363 *) Fix problem with scripts not receiving a SIGPIPE when client drops
7364 the connection (e.g., when user presses Stop). Apache will now stop
7365 trying to send a message body immediately after an error from write.
7366 [Roy Fielding and Nathan Kurz] PR#335
7368 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
7369 than mod_alias, and mod_alias has higher priority than mod_proxy;
7370 rearranged other modules to enhance understanding of their purpose
7371 and relative order (and maybe even reduce some overhead).
7372 [Roy Fielding and Sameer Parekh]
7374 *) Fix graceful restart. Eliminate many signal-related race
7375 conditions in both forms of restart, and in SIGTERM. See
7376 htdocs/manual/stopping.html for details on stopping and
7377 restarting the parent. [Dean Gaudet]
7379 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
7380 memory allocator to avoid a behaviour that required extra blocks to
7381 be allocated. [Dean Gaudet]
7383 *) Allow suexec to access files relative to current directory but not
7384 above. (Excluding leading / or any .. directory.) [Ken Coar]
7387 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
7388 PR#367, 368, 354, 453
7390 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
7391 while obtaining the /~user and save the username in a separate data
7392 area so that it won't be overwritten by the call to getgrgid(), and
7393 fix some misuse of the pool string allocation functions. Also fixes
7394 a general problem with parsing URL query info into args for CGI scripts.
7395 [Roy Fielding] PR#339, 367, 354, 453
7397 *) Fix IRIX warning about bzero undefined. [Marc Slemko]
7399 *) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
7401 *) Corrected spelling of "authoritative". AuthDBAuthoratative became
7402 AuthDBAuthoritative. [Marc Slemko] PR#420
7404 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
7406 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
7407 object that can't be PUT, or FOOBAR for some method FOOBAR that
7408 apache doesn't know about at all). Log 404s that occur in mod_include.
7409 [Paul Sutton, John Van Essen]
7411 *) If a soft timeout (or lingerout) occurs while trying to flush a
7412 buffer or write inside buff.c or fread'ing from a CGI's output,
7413 then the timeout would be ignored. [Roy Fielding] PR#373
7415 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
7416 parsing of headers. If the terminating empty-line CRLF occurs starting
7417 at the 256th or 257th byte of output, then Navigator will think a normal
7418 image is invalid. We are guessing that this is because their initial
7419 read of a new request uses a 256 byte buffer. We check the bytes written
7420 so far and, if we are about to tickle the bug, we instead insert a
7421 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
7423 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
7424 of an external redirection. [Roy Fielding and Paul Sutton]
7426 *) Configure would create a broken Makefile if the configuration file
7427 contained a commented-out Rule. [Roy Fielding]
7429 *) Promote per_dir_config and subprocess_env from the subrequest to the
7430 main request in mod_negotiation. In particular this fixes a bug
7431 where <Files> sections wouldn't properly apply to negotiated content.
7434 *) Fix a potential deadlock in mod_cgi script_err handling.
7435 [Ralf S. Engelschall]
7437 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
7440 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
7441 .htaccess files because the RewriteBase was not replaced correctly.
7442 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
7443 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
7445 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
7446 1.x the settings are those of pre-1.2b8. For 2.x we include
7447 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
7448 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
7449 [Dean Gaudet] PR#336, PR#340
7451 *) Redirect did not preserve ?query_strings when present in the client's
7452 request. [Dean Gaudet]
7454 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
7456 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
7458 *) Add UnixWare compile/install instructions. [Chuck Murcko]
7460 *) Add mod_example (illustration of API techniques). [Ken Coar]
7462 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
7464 *) Improve handling of directories when filenames have spaces in them.
7467 *) For hosts with multiple IP addresses, try all additional addresses if
7468 necessary to get a connect. Fail only if hostent address list is
7469 exhausted. [Chuck Murcko]
7471 *) More signed/unsigned port fixes. [Dean Gaudet]
7473 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
7476 Changes with Apache 1.2b8
7478 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
7479 to it. [Marc Slemko]
7481 *) The addition of <Location> and <File> directives made the
7482 sub_req_lookup_simple() function bogus, so we now handle
7483 the special cases directly. [Dean Gaudet]
7485 *) We now try to log where the server is dumping core when a fatal
7486 signal is received. [Ken Coar]
7488 *) Improved lingering_close by adding a special timeout, removing the
7489 spurious log messages, removing the nonblocking settings (they
7490 are not needed with the better timeout), and adding commentary
7491 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
7492 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
7494 *) Send error messages about setsockopt failures to the server error
7495 log instead of stderr. [Roy Fielding]
7497 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
7499 *) Stopgap solution for CGI 3-second delay with server-side includes: if
7500 processing a subrequest, allocate memory from r->main->pool instead
7501 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
7502 in the middle of an SSI request. [Dean Gaudet] PR #122
7504 *) Fixed status of response when POST is received for a nonexistent URL
7505 (was sending 405, now 404) and when any method is sent with a
7506 full-URI that doesn't match the server and the server is not acting
7507 as a proxy (was sending 501, now 403). [Roy Fielding]
7509 *) Host port changed to unsigned short. [Ken Coar] PR #276
7511 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
7513 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
7515 *) Report extra info from errno with many errors that cause httpd to exit.
7516 spawn_child, popenf, and pclosef now have valid errno returns in the
7517 event of an error. Correct problems where errno was stomped on
7518 before being reported. [Dean Gaudet]
7520 *) In the proxy, if the cache filesystem was full, garbage_coll() was
7521 never called, and thus the filesystem would remain full indefinitely.
7522 We now also remove incomplete cache files left if the origin server
7523 didn't send a Content-Length header and either the client has aborted
7524 transfer or bwrite() to client has failed. [Petr Lampa]
7526 *) Fixed the handling of module and script-added header fields.
7527 Improved the interface for sending header fields and reduced
7528 the duplication of code between sending okay responses and errors.
7529 We now always send both headers_out and err_headers_out, and
7530 ensure that the server-reserved fields are not being overridden,
7531 while not overriding those that are not reserved. [Roy Fielding]
7533 *) Moved transparent content negotiation fields to err_headers_out
7534 to reflect above changes. [Petr Lampa]
7536 *) Fixed the determination of whether or not we should make the
7537 connection persistent for all of the cases where some other part
7538 of the server has already indicated that we should not. Also
7539 improved the ordering of the test so that chunked encoding will
7540 be set whenever it is desired instead of only when KeepAlive
7541 is enabled. Added persistent connection capability for most error
7542 responses (those that do not indicate a bad input stream) when
7543 accessed by an HTTP/1.1 client. [Roy Fielding]
7545 *) Added missing timeouts for sending header fields, error responses,
7546 and the last chunk of chunked encoding, each of which could have
7547 resulted in a process being stuck in write forever. Using soft_timeout
7548 requires that the sender check for an aborted connection rather than
7549 continuing after an EINTR. Timeouts that used to be initiated before
7550 send_http_header (and never killed) are now initiated only within or
7551 around the routines that actually do the sending, and not allowed to
7552 propagate above the caller. [Roy Fielding]
7554 *) mod_auth_anon required an @ or a . in the email address, not both.
7557 *) per_dir_defaults weren't set correctly until directory_walk for
7558 name-based vhosts. This fixes an obscure bug with the wrong config
7559 info being used for vhosts that share the same ip as the server.
7562 *) Improved generation of modules/Makefile to be more generic for
7563 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
7565 *) Generate makefile dependency for Configuration based on the actual
7566 name given when running the Configure process. [Dean Gaudet]
7568 *) Fixed problem with vhost error log not being set prior to
7569 initializing virtual hosts. [Dean Gaudet]
7571 *) Fixed infinite loop when a trailing slash is included after a type map
7572 file URL (extra path info). [Petr Lampa]
7574 *) Fixed server status updating of per-connection counters. [Roy Fielding]
7576 *) Add documentation for DNS issues (reliability and security), and try
7577 to explain the virtual host matching process. [Dean Gaudet]
7579 *) Try to continue gracefully by disabling the vhost if a DNS lookup
7580 fails while parsing the configuration file. [Dean Gaudet]
7582 *) Improved calls to setsockopt. [Roy Fielding]
7584 *) Negotiation changes: Don't output empty content-type in variant list;
7585 Output charset in variant list; Return sooner from handle_multi() if
7586 no variants found; Add handling of '*' wildcard in Accept-Charset.
7587 [Petr Lampa and Paul Sutton]
7589 *) Fixed overlaying of request/sub-request notes and headers in
7590 mod_negotiation. [Dean Gaudet]
7592 *) If two variants' charset quality are equal and one is the default
7593 charset (iso-8859-1), then prefer the variant that was specifically
7594 listed in Accept-Charset instead of the default. [Petr Lampa]
7596 *) Memory allocation problem in push_array() -- it would corrupt memory
7597 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
7599 *) invoke_handler() doesn't handle mime arguments in content-type
7602 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
7605 *) Fixed problem with ErrorDocument not working for virtual hosts
7606 due to one of the performance changes in 1.2b7. [Dean Gaudet]
7608 *) Log an error message if we get a request header that is too long,
7609 since it may indicate a buffer overflow attack. [Marc Slemko]
7611 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
7612 not reject URLs without a double-slash, as per RFC2068 section 3.2.
7613 [Ken Coar] PR #146, #187
7615 *) Added table entry placeholder for new header_parser callback
7616 in all of the distributed modules. [Ken Coar] PR #191
7618 *) Allow for cgi files without the .EXE extension on them under OS/2.
7619 [Garey Smiley] PR #59
7621 *) Fixed error message when resource is not found and URL contains
7622 path info. [Petr Lampa and Dean Gaudet] PR #40
7624 *) Fixed user and server confusion over what should be a virtual host
7625 and what is the main server, resulting in access to something
7626 other than the name defined in the virtualhost directive (but
7627 with the same IP address) failing. [Dean Gaudet]
7629 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
7630 AIX; improves the redirection stuff to enable the users to generally
7631 redirect to http, https, gopher and ftp; added TIME variable for
7632 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
7633 special patterns >STRING, <STRING and =STRING to RewriteCond, which
7634 can be used in conjunction with %{TIME} or other variables to create
7635 time-dependent rewriting rules. [Ralf S. Engelschall]
7637 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
7638 Module authors may need to adjust their code for proper cleanup to take
7639 place (that is, call note_cleanups_for_fd()). This change fixes problems
7640 with file descriptors being erroneously closed when the proxy module was
7641 in use. [Ben Laurie]
7643 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
7644 initgroups() to hose the group information needed for later
7645 comparisons. [Randy Terbush]
7647 *) Remove unnecessary call to va_end() in create_argv() which
7648 caused a SEGV on some systems.
7650 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
7653 *) Clear memory allocated for listeners. [Randy Terbush]
7655 *) Improved handling of IP address as a virtualhost address and
7656 introduced "_default_" as a synonym for the default vhost config.
7657 [Dean Gaudet] PR #212
7659 Changes with Apache 1.2b7
7661 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
7663 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
7665 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
7666 - replace protocol response numbers with symbols
7667 - save variant-list into main request notes
7668 - free allocated memory from subrequests
7669 - merge notes, headers_out and err_headers_out
7671 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
7672 "HTTP/#.# ###*" to be more lenient about what we accept.
7675 *) more proxy FTP bug fixes:
7676 - Changed send_dir() to remove user/passwd from displayed URL.
7677 - Changed login error messages to be more descriptive.
7678 - remove setting of SO_DEBUG socket option
7679 - Make ftp_getrc() more lenient about multiline responses,
7680 specifically, 230 responses which don't have continuation 230-
7681 on each line). These seem to be all NT FTP servers, and while
7682 perhaps questionable, they appear to be legal by RFC 959.
7683 - Add missing kill_timeout() after transfer to user completes.
7686 *) Fixed problem where a busy server could hang when restarting
7687 after being sent a SIGHUP due to child processes not exiting.
7690 *) Modify mod_include escaping so a '\' only signifies an escaped
7691 character if the next character is one that needs
7692 escaping. [Ben Laurie]
7694 *) Eliminated possible infinite loop in mod_imap when relative URLs are
7695 used with a 'base' directive that does not have a '/' in it.
7696 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
7698 *) Reduced the default timeout from 1200 seconds to 300, and the
7699 one in the sample configfile from 400 to 300. [Marc Slemko]
7701 *) Stop vbprintf from crashing if given a NULL string pointer;
7702 print (null) instead. [Ken Coar]
7704 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
7705 [Marc Slemko and Roy Fielding]
7707 *) Fixed problem with mod_cgi-generated internal redirects trying to
7708 read the request message-body twice. [Archie Cobbs and Roy Fielding]
7710 *) Reduced timeout on lingering close, removed possibility of a blocked
7711 read causing the child to hang, and stopped logging of errors if
7712 the socket is not connected (reset by client). [Roy Fielding]
7714 *) Rearranged main child loop to remove duplication of code in
7715 select/accept and keep-alive requests, fixed several bugs regarding
7716 checking scoreboard_image for exit indication and failure to
7717 account for all success conditions and trap all error conditions,
7718 prevented multiple flushes before closing the socket; close the entire
7719 socket buffer instead of just one descriptor, prevent logging of
7720 EPROTO and ECONNABORTED on platforms where supported, and generally
7721 improved readability. [Roy Fielding]
7723 *) Extensive performance improvements. Cleaned up inefficient use of
7724 auto initializers, multiple is_matchexp calls on a static string,
7725 and excessive merging of response_code_strings. [Dean Gaudet]
7727 *) Added double-buffering to mod_include to improve performance on
7728 server-side includes. [Marc Slemko]
7730 *) Several fixes for suexec wrapper. [Randy Terbush]
7731 - Make wrapper work for files on NFS filesystem.
7732 - Fix portability problem of MAXPATHLEN.
7733 - Fix array overrun problem in clean_env().
7734 - Fix allocation of PATH environment variable
7736 *) Removed extraneous blank line is description of mod_status chars.
7739 *) Logging of errors from the call_exec routine simply went nowhere,
7740 since the logfile fd has been closed, so now we send them to stderr.
7741 [Harald T. Alvestrand]
7743 *) Fixed core dump when DocumentRoot is a CGI.
7744 [Ben Laurie, reported by geddis@tesserae.com]
7746 *) Fixed potential file descriptor leak in mod_asis; updated it and
7747 http_core to use pfopen/pfclose instead of fopen/fclose.
7748 [Randy Terbush and Roy Fielding]
7750 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
7751 as the DEC Alpha which is 64-bit but uses 32-bit ints.
7752 [Dean Gaudet and Ken Coar]
7754 *) Return a 302 response code to the client when sending a redirect
7755 due to a missing trailing '/' on a directory instead of a 301; now
7756 it is cacheable. [Markus Gyger]
7758 *) Fix condition where, if a bad directive occurs in .htaccess, and
7759 sub_request() goes first to this directory, then log_reason() will
7760 SIGSEGV because it doesn't have initialized r->per_dir_config.
7761 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
7763 *) Fix handling of lang_index in is_variant_better(). This was
7764 causing problems which resulted in the server sending the
7765 wrong language document in some cases. [Petr Lampa]
7767 *) Remove free() from clean_env() in suexec wrapper. This was nuking
7768 the clean environment on some systems.
7770 *) Tweak byteserving code (e.g. serving PDF files) to work around
7771 bugs in Netscape Navigator and Microsoft Internet Explorer.
7772 Emit Content-Length header when sending multipart/byteranges.
7775 *) Port to HI-UX/WE2. [Nick Maclaren]
7777 *) Port to HP MPE operating system for HP 3000 machines
7778 [Mark Bixby <markb@cccd.edu>]
7780 *) Fixed bug which caused a segmentation fault if only one argument
7781 given to RLimit* directives. [Ed Korthof]
7783 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
7785 *) Improved buffered output to the client by delaying the flush decision
7786 until the BUFF code is actually about to read the next request.
7787 This fixes a problem introduced in 1.2b5 with clients that send
7788 an extra CRLF after a POST request. Also improved chunked output
7789 performance by combining writes using writev() and removing as
7790 many bflush() calls as possible. NOTE: Platforms without writev()
7791 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
7792 or Configure, unless we have already done so. [Dean Gaudet]
7794 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
7796 *) Fixed mod_info output corruption bug introduced by buffer overflow
7797 fixes. [Dean Gaudet]
7799 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
7800 for the special case of a 304 response. [Paul Sutton]
7802 *) Improved handling of TRACE method by bypassing normal method handling
7803 and header parsing routines; fixed Allow response to always allow TRACE.
7806 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
7808 *) Cleaned-up some of the generated HTML. [Ken Coar]
7810 Changes with Apache 1.2b6
7812 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
7814 *) Fix typo introduced in fix for potential infinite loop around
7815 accept() in child_main(). This change caused the rev to 1.2b6.
7816 1.2b5 was never a public beta.
7818 Changes with Apache 1.2b5
7820 *) Change KeepAlive semantics (On|Off instead of a number), add
7821 MaxKeepAliveRequests directive. [Alexei Kosut]
7823 *) Various NeXT compilation patches, as well as a change in
7824 regex/regcomp.c since that file also used a NEXT define.
7827 *) Allow * to terminate the end of a directory match in mod_dir.
7828 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
7830 *) Don't call can_exec() if suexec_enabled. Calling this requires
7831 scripts executed by the suexec wrapper to be world executable, which
7832 defeats one of the advantages of running the wrapper. [Randy Terbush]
7834 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
7837 *) Migration from sprintf() to snprintf() to avoid buffer
7838 overflows. [Marc Slemko]
7840 *) Provide portable snprintf() implementation (ap_snprintf)
7841 as well as *cvt family. [Jim Jagielski]
7843 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
7846 *) Remove mod_fastcgi.c from the distribution. This module appears
7847 to be maintained more through the Open Market channels and should
7848 continue to be easily available at http://www.fastcgi.com/
7850 *) Fixed bug in modules/Makefile that wouldn't allow building in more
7851 than one subdirectory (or cleaning, either). [Jeremy Laidman]
7853 *) mod_info assumed that the config files were relative to ServerRoot.
7856 *) CGI scripts called as an error document resulting from failed
7857 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
7859 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
7862 *) Properly check errno to prevent display of a directory index
7863 when server receives a long enough URL to confuse stat().
7866 *) Several security enhancements to suexec wrapper. It is _highly_
7867 recommended that previously installed versions of the wrapper
7868 be replaced with this version. [Randy Terbush, Jason Dour]
7870 - ~user execution now properly restricted to ~user's home
7871 directory and below.
7872 - execution restricted to UID/GID > 100
7873 - restrict passed environment to known variables
7874 - call setgid() before initgroups() (portability fix)
7875 - remove use of setenv() (portability fix)
7877 *) Add HTTP/1.0 response forcing. [Ben Laurie]
7879 *) Add access control via environment variables. [Ben Laurie]
7881 *) Add rflush() function. [Alexei Kosut]
7883 *) remove duplicate pcalloc() call in new_connection().
7885 *) Fix incorrect comparison which could allow number of children =
7886 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
7887 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
7889 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
7890 AIX PS/2, CONVEXOS. [Jim Jagielski]
7892 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
7893 It's more portable. [Martin Kraemer]
7895 *) Replace references to make in Makefile.tmpl with $(MAKE).
7898 *) Add ProxyBlock directive w/IP address caching. Add IP address
7899 caching to NoCache directive as well. ProxyBlock works with all
7900 handlers; NoCache now also works with FTP for anonymous logins.
7901 Still more code cleanup. [Chuck Murcko]
7903 *) Add "header parse" API hook [Ben Laurie]
7905 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
7907 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
7909 *) Correctly allow access and auth directives in <Files> sections in
7910 server config files. [Alexei Kosut]
7912 *) Fix bug with ServerPath that could cause certain files to be not
7913 found by the server. [Alexei Kosut]
7915 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
7916 double-quote from text and so that it properly checks for unsupported
7917 status codes using the new index_of_response interface. [Roy Fielding]
7919 *) Multiple fixes to the lingering_close code in order to avoid being
7920 interrupted by a stray timeout, to avoid lingering on a connection
7921 that has already been aborted or never really existed, to ensure that
7922 we stop lingering as soon as any error condition is received, and to
7923 prevent being stuck indefinitely if the read blocks. Also improves
7924 reporting of error conditions. [Marc Slemko and Roy Fielding]
7926 *) Fixed initialization of parameter structure for sigaction.
7927 [mgyger@itr.ch, Adrian Filipi-Martin]
7929 *) Fixed reinitializing the parameters before each call to accept and
7930 select, and removed potential for infinite loop in accept.
7931 [Roy Fielding, after useful PR from adrian@virginia.edu]
7933 *) Fixed condition where, if a child fails to fork, the scoreboard would
7934 continue to say SERVER_STARTING forever. Eventually, the main process
7935 would refuse to start new children because count_idle_servers() will
7936 count those SERVER_STARTING entries and will always report that there
7937 are enough idle servers. [Phillip Vandry]
7939 *) Fixed bug in bcwrite regarding failure to account for partial writes.
7940 Avoided calling bflush() when the client is pipelining requests.
7941 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
7943 *) Added description of "." mode in server-status [Jim Jagielski]
7945 Changes with Apache 1.2b4
7947 *) Fix possible race condition in accept_mutex_init() that
7948 could leave a small security hole open allowing files to be
7949 overwritten in cases where the server UID has write permissions.
7952 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
7954 *) Fix portablity problem in util_script where ARG_MAX may not be
7955 defined for some systems.
7957 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
7960 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
7961 style magic #! token for better script portability. [Garey Smiley]
7963 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
7964 execution for ~userdir CGI. [Jason Dour]
7966 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
7968 *) Fix month off by one in suexec wrapper logging.
7970 Changes with Apache 1.2b3:
7972 *) Fix error in mod_cgi which could cause resources not to be properly
7973 freed, or worse. [Dean Gaudet]
7975 *) Fix find_string() NULL pointer dereference. [Howard Fear]
7977 *) Add set_flag_slot() at the request of Dirk and others.
7980 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
7982 *) Add changes to improve the error message given for invalid
7983 ServerName parameters. [Dirk vanGulik]
7985 *) Add "Authoritative" directive for Auth modules that don't
7986 currently have it. This gives admin control to assign authoritative
7987 control to an authentication scheme and allow "fall through" for
7988 those authentication modules that aren't "Authoritative" thereby
7989 allowing multiple authentication mechanisms to be chained.
7992 *) Remove requirement for ResourceConfig/AccessConfig if not using
7993 the three config file layout. [Randy Terbush]
7995 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
7997 *) Changes to suexec wrapper to fix the following problems:
7998 1. symlinked homedirs will kill ~userdirs.
7999 2. initgroups() on Linux 2.0.x clobbers gr->grid.
8000 3. CGI command lines paramters problems
8001 4. pw-pwdir for "docroot check" still the httpd user's pw record.
8002 [Randy Terbush, Jason Dour]
8004 *) Change create_argv() to accept variable arguments. This fixes
8005 a problem where arguments were not getting passed to the CGI via
8006 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
8008 *) Collapse multiple slashes in path URLs to properly apply
8009 handlers defined by <Location>. [Alexei Kosut]
8011 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
8013 *) Improve the accuracy of request duration timings by setting
8014 r->request_time in read_request_line() instead of read_request().
8017 *) Reset timeout while reading via get_client_block() in mod_cgi.c
8018 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
8020 *) Add the ability to pass different Makefile.tmpl files to Configure
8021 using the -make flag. [Rob Hartill]
8023 *) Fix coredump triggered when sending a SIGHUP to the server caused
8024 by an assertion failure, in turn caused by an uninitialised field in a
8028 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
8029 PATH_INFO from previous versions of Apache (in certain situations,
8030 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
8031 [later removed in 1.2b11]
8033 *) Add rwrite() function to API to allow for sending strings of
8034 arbitrary length. [Doug MacEachern]
8036 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
8038 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
8039 NeXT. [Jim Jagielski]
8041 *) Removed recent modification to promote the status code on internal
8042 redirects, since the correct fix was to change the default log format
8043 in mod_log_config so that it outputs the original status. [Rob Hartill]
8045 Changes with Apache 1.2b2:
8047 *) Update set_signals() to use sigaction() for setting handlers.
8048 This appears to fix a re-entrant problem in the seg_fault()
8049 bus_error() handlers. [Randy Terbush]
8051 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
8053 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
8055 *) proxy_http.c bugfixes: [Chuck Murcko]
8056 1) fixes possible NULL pointer reference w/NoCache
8057 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
8058 host would cache nothing if it was in the local domain,
8059 and the local domain was in the NoCache list)
8060 3) Adds Host: header when not available
8061 4) Some code cleanup and clarification
8063 *) mod_include.c bugfixes:
8064 1) Fixed an ommission that caused include variables to not
8065 be parsed in config errmsg directives [Howard Fear]
8066 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
8067 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
8068 4) Allow backslash-escaping to all quoted text
8069 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
8070 5) Pass variable to command line if not set in XSSI's env
8073 *) Fix infinite loop when processing Content-language lines in
8074 type-map files. [Alexei Kosut]
8076 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
8078 *) Fixed problem in set_[user|group] that prevented CGI execution
8079 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
8081 *) Added PORTING information file. [Jim Jagielski]
8083 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
8085 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
8087 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
8088 USE_FCNTL_SERIALIZED_ACCEPT was intended.
8090 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
8091 which caused problems of systems where socket s_addr is >32bits.
8093 *) Added comment to explain (r->chunked = 1) side-effect in
8094 http_protocol.c [Roy Fielding]
8096 *) Replaced use of index() in mod_expires.c with more appropriate
8097 and portable isdigit() test. [Ben Laurie]
8099 *) Updated Configure for ...
8100 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
8101 *-dg-dgux* (bad pattern match)
8102 QNX (DEF_WANTHSREGEX=yes)
8103 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
8106 and added some user diagnostic info. [Ben Laurie]
8108 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
8109 for better portability. [Jim Jagielski]
8111 *) Updated helpers/GuessOS for ...
8112 SCO 5 (recognize minor releases)
8113 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
8114 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
8115 IRIX64 (-sgi-irix64)
8116 ULTRIX (-unknown-ultrix)
8117 SINIX (-whatever-sysv4)
8118 NCR Unix (-ncr-sysv4)
8119 and fixed something in helpers/PrintPath [Ben Laurie]
8121 Changes with Apache 1.2b1
8123 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
8125 Changes with Apache 1.1.1
8127 *) Fixed bug where Cookie module would make two entries in the
8128 logfile for each access [Mark Cox]
8130 *) Fixed bug where Redirect in .htaccess files would cause memory
8131 leak. [Nathan Neulinger]
8133 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
8135 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
8137 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
8139 Changes with Apache 1.1.0
8141 *) Bring NeXT support up to date. [Takaaki Matsumoto]
8143 *) Bring QNX support up to date. [Ben Laurie]
8145 *) Make virtual hosts default to main server keepalive parameters.
8146 [Alexei Kosut, Ben Laurie]
8148 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
8150 *) Fix missing address family for connect, also remove unreachable statement
8151 in mod_proxy. [Ben Laurie]
8153 *) mod_env now turned on by default in Configuration.tmpl.
8155 *) Bugs which were fixed:
8156 a) yet more mod_proxy bugs [Ben Laurie]
8157 b) CGI works again with inetd [Alexei Kosut]
8158 c) Leading colons were stripped from passwords [osm@interguide.com]
8159 d) Another fix to multi-method Limit problem [jk@tools.de]
8161 Changes with Apache 1.1b4
8163 *) r->bytes_sent variable restored. [Robert Thau]
8165 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
8167 *) More possibly unsecure programs removed from the support directory.
8169 *) More mod_auth_msql authentication improvements.
8171 *) VirtualHosts based on Host: headers no longer conflict with the
8174 *) OS/2 compatibility enhancements. [Gary Smiley]
8176 *) POST now allowed to directory index CGI scripts.
8178 *) Actions now work with files of the default type.
8180 *) Bugs which were fixed:
8181 a) more mod_proxy bugs
8182 b) early termination of inetd requests
8183 c) compile warnings on several systems
8184 d) problems when scripts stop reading output early
8186 Changes with Apache 1.1b3
8188 *) Much of cgi-bin and all of cgi-src has been removed, due to
8189 various security holes found and that we could no longer support
8192 *) The "Set-Cookie" header is now special-cased to not merge multiple
8193 instances, since certain popular browsers can not handle multiple
8194 Set-Cookie instructions in a single header. [Paul Sutton]
8196 *) rprintf() added to buffer code, occurrences of sprintf removed.
8199 *) CONNECT method for proxy module, which means tunneling SSL should work.
8200 (No crypto needed) Also a NoCache config directive.
8202 *) Several API additions: pstrndup(), table_unset() and get_token()
8203 functions now available to modules.
8205 *) mod_imap fixups, in particular Location: headers are now complete
8208 *) New "info" module which reports on installed module set through a
8209 special URL, a la mod_status.
8211 *) "ServerPath" directive added - allows for graceful transition
8212 for Host:-header-based virtual hosts.
8214 *) Anonymous authentication module improvements.
8216 *) MSQL authentication module improvements.
8218 *) Status module design improved - output now table-based. [Ben Laurie]
8220 *) htdigest utility included for use with digest authentication
8223 *) mod_negotiation: Accept values with wildcards to be treated with
8224 less priority than those without wildcards at the same quality
8225 value. [Alexei Kosut]
8227 *) Bugs which were fixed:
8228 a) numerous mod_proxy bugs
8229 b) CGI early-termination bug [Ben Laurie]
8230 c) Keepalives not working with virtual hosts
8231 d) RefererIgnore problems
8232 e) closing fd's twice in mod_include (causing core dumps on
8233 Linux and elsewhere).
8235 Changes with Apache 1.1b2
8238 a) core dumps in mod_digest
8239 b) truncated hostnames/ip address in the logs
8240 c) relative URL's in mod_imap map files
8242 Changes with Apache 1.1b1
8244 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
8246 Changes with Apache 1.0.3
8248 *) Internal redirects which occur in mod_dir.c now preserve the
8249 query portion of a request (the bit after the question mark).
8252 *) Escape active characters '<', '>' and '&' in html output in
8253 directory listings, error messages and redirection links.
8256 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
8258 *) Fix for POSIX compliance in waiting for processes in alloc.c.
8261 *) setsockopt no longer takes a const declared argument [Martijn Koster]
8263 *) Reset timeout timer after each successful fwrite() to the network.
8264 This patch adds a reset_timeout() procedure that is called by
8265 send_fd() to reset the timeout ever time data is written to the net.
8268 *) timeout() signal handler now checks for SIGPIPE and reports
8269 lost connections in a more user friendly way. [Rob Hartill]
8271 *) Location of the "scoreboard" file which used to live in /tmp is
8272 now configurable (for OSes that can't use mmap) via ScoreBoardFile
8273 which works similar to PidFile (in httpd.conf) [Rob Hartill]
8275 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
8277 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
8278 which caused a SEGV with cookies enabled
8280 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
8283 *) Log the UNIX textual error returned by some system calls, in
8284 particular errors from accept() [David Robinson]
8286 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
8288 Changes with Apache 1.0.2
8290 *) patch to get Apache compiled on UnixWare 2.x, recommended as
8291 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
8293 *) Fix get_basic_auth_pw() to set the auth_type of the request.
8296 *) past changes to http_config.c to only use the
8297 setrlimit function on systems defining RLIMIT_NOFILE
8298 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
8299 for SUNOS and prototypes the needed functions.
8301 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
8304 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
8306 *) Merge multiple headers from CGI scripts instead of taking last
8307 one. [David Robinson]
8309 *) Add support for SCO 5. [Ben Laurie]
8311 Changes with Apache 1.0.1
8313 *) Silence mod_log_referer and mod_log_agent if not configured
8316 *) Recursive includes can occur if the client supplies PATH_INFO data
8317 and the server provider uses relative links; as file.html
8318 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
8320 *) The replacement for initgroups() did not call {set,end}grent(). This
8321 had two implications: if anything else used getgrent(), then
8322 initgroups() would fail, and it was consuming a file descriptor.
8325 *) On heavily loaded servers it was possible for the scoreboard to get
8326 out of sync with reality, as a result of a race condition.
8327 The observed symptoms are far more Apaches running than should
8328 be, and heavy system loads, generally followed by catastrophic
8329 system failure. [Ben Laurie]
8331 *) Fix typo in license. [David Robinson]
8333 Changes with Apache 1.0.0 23 Nov 1995
8335 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
8337 Changes with Apache 0.8.16 05 Nov 1995
8339 *) New man page for 'httpd' added to support directory [David Robinson]
8341 *) .htgroup files can have more than one line giving members for a
8342 given group (each must have the group name in front), for NCSA
8343 back-compatibility [Robert Thau]
8345 *) Mutual exclusion around accept() is on by default for SVR4 systems
8346 generally, since they generally can't handle multiple processes in
8347 accept() on the same socket. This should cure flaky behavior on
8348 a lot of those systems. [David Robinson]
8350 *) AddType, AddEncoding, and AddLanguage directives take multiple
8351 extensions on a single command line [David Robinson]
8353 *) UserDir can be disabled for a given virtual host by saying
8354 "UserDir disabled" in the <VirtualHost> section --- it was a bug
8355 that this didn't work. [David Robinson]
8357 *) Compiles on QNX [Ben Laurie]
8359 *) Corrected parsing of ctime time format [David Robinson]
8361 *) httpd does a perror() before exiting if it can't log its pid
8362 to the PidFile, to make diagnosing the error a bit easier.
8365 *) <!--#include file="..."--> can no longer include files in the
8366 parent directory, for NCSA back-compatibility. [David Robinson]
8368 *) '~' is *not* escaped in URIs generated for directory listings
8371 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
8373 *) Fixed bug involving handling URIs with escaped %-characters
8374 in redirects [David Robinson]
8376 Changes with Apache 0.8.15 14 Oct 1995
8378 *) Switched to new, simpler license
8380 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
8382 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
8384 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
8386 *) Correctly handles internal redirects to files with names containing '%'
8389 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
8391 *) Use geteuid() rather than getuid() to see if we have root privilege,
8392 so that server correctly resets privilege if run setuid root. [Andrew
8395 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
8398 *) Fix relative URLs in imagemap files [Randy Terbush]
8400 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
8403 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
8404 entries all name the same one. [David Robinson]
8406 *) Fix directory listings with filenames containing unusual characters
8409 *) Better URI-escaping for generated URIs in directories with filenames
8410 containing unusual characters [Ben Laurie]
8412 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
8414 *) Unblock alarms on error return from spawn_child() [David Robinson]
8416 *) Sample Config files have extra note for SCO users [Ben Laurie]
8418 *) Configuration has note for HP-UX users [Rob Hartill]
8420 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
8422 *) Nuked bogus #define in httpd.h [David Robinson]
8424 *) Better test for whether a system has setrlimit() [David Robinson]
8426 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
8428 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
8431 Changes with Apache 0.8.14 19 Sep 1995
8433 *) Compiles on SCO ODT 3.0 [Ben Laurie]
8435 *) AddDescription works (better) [Ben Laurie]
8437 *) Leaves an intelligible error diagnostic when it can't set group
8438 privileges on standalone startup [Andrew Wilson]
8440 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
8441 that machine, which claims to be BSD but does not support RLIMIT.
8444 *) gcc -Wall no longer complains about an unused variable when util.c
8445 is compiled with -DMINIMAL_DNS [Andrew Wilson]
8447 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
8449 Changes with Apache 0.8.13 07 Sep 1995
8451 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
8453 *) Have built-in imagemap code recognize & honor Point directive [James
8456 *) Generate cleaner directory listings in directories with a mix of
8457 long and short filenames [Rob Hartill]
8459 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
8461 *) Properly default ServerName for virtual servers [Robert Thau]
8463 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
8464 Paul Richards and a cast of thousands...]
8466 *) On self-identified BSD systems (we don't try to guess any more),
8467 allocate a few extra file descriptors per virtual host with setrlimit,
8468 if we can, to avoid running out. [Randy Terbush]
8470 *) Write 22-character lock file name into buffer with enough space
8471 on startup [Konstantin Olchanski]
8473 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
8476 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
8478 *) Suppress -Wall warning by initializing variable in negotiation code
8479 [Tobias Weingartner]
8481 Changes with Apache 0.8.12 31 Aug 1995
8483 *) Doesn't pause three seconds after including a CGI script which is
8484 too slow to die off (this is done by not even trying to kill off
8485 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
8486 after the entire document has been processed). [Robert Thau]
8488 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
8490 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
8492 *) Allows .htaccess files to override <Directory> sections naming the
8493 same directory [David Robinson]
8495 *) Removed an efficiency hack in sub_req_lookup_uri which was
8496 causing certain extremely marginal cases (e.g., ScriptAlias of a
8497 *particular* index.html file) to fail. [David Robinson]
8499 *) Doesn't log an error when the requested URI requires
8500 authentication, but no auth header line was supplied by the
8501 client; this is a normal condition (the client doesn't no auth is
8502 needed here yet). [Robert Thau]
8504 *) Behaves more sanely when the name server loses its mind [Sean Welch]
8506 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
8508 *) RFC931 code no longer passes out name of prior clients on current
8509 requests if the current request came from a server that doesn't
8510 do RFC931. [David Robinson]
8512 *) Configuration script accepts "Module" lines with trailing whitespace.
8515 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
8517 *) Cleaned up comments in mod_cgi.c [Robert Thau]
8519 Changes with Apache 0.8.11 24 Aug 1995
8521 *) Wildcard <Directory> specifications work. [Robert Thau]
8523 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
8525 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
8526 the file being requested itself, in addition to the directories leading
8527 up to it. [Robert Thau]
8529 *) Logs access failures due to symlink checks or invalid client address
8530 in the error log [Roy Fielding, Robert Thau]
8532 *) Symlink checks deal correctly with systems where lstat of
8533 "/path/to/some/link/" follows the link. [Thau, Fielding]
8535 *) Doesn't reset DirectoryIndex to 'index.html' when
8536 other directory options are set in a .htaccess file. [Robert Thau]
8538 *) Clarified init code and nuked bogus warning in mod_access.c
8541 *) Corrected several directives in sample srm.conf
8542 --- includes corrections to directory indexing icon-related directives
8543 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
8544 icons for encodings right, and turning on AddEncoding by default).
8547 *) Corrected descriptions of args to AddIcon and AddAlt in command table
8550 *) INSTALL & README mention "contributed modules" directory [Brian
8553 *) Fixed English in the license language... "for for" --> "for".
8556 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
8557 mod_alias.c, merging it almost completely with handling of Alias, and
8558 adding a 'notes' field to the request_rec which allows the CGI module
8559 to discover whether the Alias module has put this request through
8560 ScriptAlias (which it needs to know for back-compatibility, as the old
8561 NCSA code did not check Options ExecCGI in ScriptAlias directories).
8564 Changes with Apache 0.8.10 18 Aug 1995
8566 *) AllowOverride applies to the named directory, and not just
8567 subdirectories. [David Robinson]
8569 *) Do locking for accept() exclusion (on systems that need it)
8570 using a special file created for the purpose in /usr/tmp, and
8571 not the error log; using the error log causes real problems
8572 if it's NFS-mounted; this is known to be the cause of a whole
8573 lot of "server hang" problems with Solaris. [David Robinson;
8574 thanks to Merten Schumann for help diagnosing the problem].
8576 Changes with Apache 0.8.9 12 Aug 1995
8578 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
8580 *) Nested includes see environment variables of the including document,
8581 for NCSA bug-compatibility (some sites have standard footer includes
8582 which try to print out the last-modified date). [Eric Hagberg/Robert
8585 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
8586 URI as a CGI script, even if it would have been treated as something
8587 else if requested directly, for NCSA back-compatibility. (Note that
8588 this means that people who know the name of the script can see the
8589 code just by asking for it). [Robert Thau]
8591 *) New version of dbmmanage script included in support directory as
8594 *) Check if scoreboard file couldn't be opened, and say so, rather
8595 then going insane [David Robinson]
8597 *) POST to CGI works on A/UX [Jim Jagielski]
8599 *) AddIcon and AddAlt commands work properly [Rob Hartill]
8601 *) NCSA server push works properly --- the Arena bug compatibility
8602 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
8603 if you still want the workaround). [Rob Hartill]
8605 *) If client didn't submit any Accept-encodings, ignore encodings in
8606 content negotiation. (NB this will all have to be reworked anyway
8607 for the new HTTP draft). [Florent Guillaume]
8609 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
8611 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
8613 *) Give Redirect priority over Alias, for NCSA bug compatibility
8616 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
8617 paralleling earlier bug fix for CGI [David Robinson]
8619 *) If DBM auth is improperly configured, report a server error and don't
8622 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
8623 it seems to work well enough without it (even in a 10 hits/sec
8624 workout), and the overhead for the locking under A/UX is
8625 alarmingly high (though it is very low on other systems).
8626 [Eric Hagberg, Jim Jagielski]
8628 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
8630 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
8631 Behlendorf/Eric Hagberg]
8633 *) More improvements to default Configuration for A/UX [Jim Jagielski]
8635 *) Compiles clean on NEXT [Rob Hartill]
8637 *) Compiles clean on SGI [Robert Thau]
8639 Changes with Apache 0.8.8 08 Aug 1995
8641 *) SunOS library prototypes now never included unless explicitly
8642 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
8643 people using GNU libc on SunOS are screwed by prototypes for the
8646 (Those who wish to compile clean with gcc -Wall on a standard
8647 SunOS setup need the prototypes, and may obtain them using
8648 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
8649 with nonstandard libraries are presumably competent to make their
8652 *) Strips trailing '/' characters off both args to the Alias command,
8653 to make 'Alias /foo/ /bar/' work.
8655 Changes with Apache 0.8.7 03 Aug 1995
8657 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
8658 [reported by David Robinson]
8660 *) Compiles clean on OSF/1 [David Robinson]
8662 *) Added some of the more recent significant changes (AddLanguage stuff,
8663 experimental LogFormat support) to CHANGES file in distribution root
8666 Changes with Apache 0.8.6 02 Aug 1995
8668 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
8669 (If you actually wanted a conditional GET which bypassed the cache, you
8670 couldn't get it). [Reported by Roy Fielding]
8672 *) Properly terminate headers on '304 Not Modified' replies to conditional
8673 GETs --- no browser we can find cares much, but the CERN proxy chokes.
8674 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
8676 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
8678 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
8679 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
8680 and older versions don't set the __SUNPRO_C preprocessor variable). On
8681 all other systems, these are never used anyway. [Reported by Mark Cox].
8683 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
8685 Changes with Apache 0.8.5 01 Aug 1995
8687 *) Added last-minute configurable log experiment, as optional module
8689 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
8690 properly. (One-line fix to http_protocol.c).
8692 *) Work around bogus behavior when reloading from Netscape.
8693 It's Netscape's bug --- for some reason they expect a request with
8694 If-modified-since: to not function as a conditional GET if it also
8695 comes with Pragma: no-cache, which is way out of line with the HTTP
8696 spec (according to Roy Fielding, the redactor).
8698 *) Added parameter to set maximum number of server processes.
8700 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
8703 *) IdentityCheck bugfix [Chuck Murcko].
8705 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
8707 *) More sample config file corrections; add extension to AddType for
8708 *.asis, move AddType generic description to its proper place, and
8709 fix miscellaneous typos. [ Alexei Kosut ]
8711 *) Deleted the *other* reference to the regents from the Berkeley
8712 legal disclaimer (everyplace).
8714 *) Nuked Shambhala name from src/README; had already cleaned it out
8717 Changes with Apache 0.8.4
8719 *) Changes to server-pool management parms --- renamed current
8720 StartServers to MinSpareServers, created separate StartServers
8721 parameter which means what it says, and renamed MaxServers to
8722 MaxSpareServers (though the old name still works, for NCSA 1.4
8723 back-compatibility). The old names were generally regarded as
8724 too confusing. Also altered "docs" in sample config files.
8726 *) More improvements to default config files ---
8727 sample directives (commented out) for XBitHack, BindAddress,
8728 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
8729 defaults, AddTypes for send-as-is and imagemap magic types, and
8730 improvements to samples for DirectoryIndex [Alexei Kosut]
8732 *) Yet more improvements to default config files --- changes to
8733 Alexei's sample AddLanguage directives, and sample LanguagePriority
8734 [ Florent Guillaume ]
8736 *) Set config file locations properly if not set in httpd.conf
8739 *) Don't escape URIs in internal redirects multiple times; don't
8740 do that when translating PATH_INFO to PATH_TRANSLATED either.
8743 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
8745 Changes with Apache 0.8.3
8747 *) Edited distribution README to *briefly* summarize installation
8748 procedures, and give a pointer to the INSTALL file in the src/
8751 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
8752 recent NCSA distributions.
8754 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
8755 exist for the same directory, use both and don't segfault. [Reported
8758 *) Proper makefile dependencies [David Robinson]
8760 *) Note (re)starts in error log --- reported by Rob Hartill.
8762 *) Only call no2slash() after get_path_info() has been done, to
8763 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
8764 reported by Andrew Wilson, though this one is probably a real bug]
8766 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
8767 dump core when Referer is not supplied. [Randy Terbush]
8769 *) Lightly edited sample config files to refer people to our documentation
8770 instead of NCSA's, and to list Rob McCool as *original* author (also
8771 deleted his old, and no doubt non-functional email address). Would be
8772 nice to have examples of new features...
8774 Changes with Apache 0.8.2 19 Jul 1995
8776 *) Added AddLanuage code [Florent Guillaume]
8778 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
8780 *) All sorts of problems when MultiViews finds a directory. It would
8781 be nice if mod_dir.c was robust enough to handle that, but for now,
8782 just punt. [reported by Brian Behlendorf]
8784 *) Wait for all children on restart, to make sure that the old socket
8785 is gone and we can reopen it. [reported by Randy Terbush]
8787 *) Imagemap module is enabled in default Configuration
8789 *) RefererLog and UserAgentLog modules properly default the logfile
8792 *) Mark Cox's mod_cookies added to the distribution as an optional
8793 module (commented out in the default Configuration, and noted as
8794 an experiment, along with mod_dld). [Mark Cox]
8796 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
8798 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
8800 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
8802 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
8805 Changes with Apache 0.8.1
8807 *) New imagemap module [Randy Terbush]
8809 *) Replacement referer log module with NCSA-compatible RefererIgnore
8810 [Matthew Gray again]
8812 *) Don't mung directory listings with very long filenames.
8815 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
8817 *) New config script. See INSTALL for info. [Robert Thau]
8819 *) Scoreboard mechanism for regulating the number of extant server
8820 processes. MaxServers and StartServers defaults are the same as
8821 for NCSA, but the meanings are slightly different. (Actually,
8822 I should probably lower the MaxServers default to 10).
8824 Before asking for a new connection, each server process checks
8825 the number of other servers which are also waiting for a
8826 connection. If there are more than MaxServers, it quietly dies
8827 off. Conversely, every second, the root, or caretaker, process
8828 looks to see how many servers are waiting for a new connection;
8829 if there are fewer than StartServers, it starts a new one. This
8830 does not depend on the number of server processes already extant.
8831 The accounting is arranged through a "scoreboard" file, named
8832 /tmp/htstatus.*, on which each process has an independent file
8833 descriptor (they need to seek without interference).
8835 The end effect is that MaxServers is the maximum number of
8836 servers on an *inactive* server machine, but more will be forked
8837 off to handle unusually heavy loads (or unusually slow clients);
8838 these will die off when they are no longer needed --- without
8839 reverting to the overhead of full forking operation. There is a
8840 hard maximum of 150 server processes compiled in, largely to
8841 avoid forking out of control and dragging the machine down.
8842 (This is arguably too high).
8844 In my server endurance tests, this mechanism did not appear to
8845 impose any significant overhead, even after I forced it to put the
8846 scoreboard file on a normal filesystem (which might have more
8847 overhead than tmpfs). [Robert Thau]
8849 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
8852 *) Read .htaccess files even in directory with <Directory> section.
8853 (Former incompatibility noted on mailing list, now fixed). [Robert
8856 *) "HEAD /" gives the client a "Bad Request" error message, rather
8857 than trying to send no body *and* no headers. [Cliff Skolnick].
8859 *) Don't produce double error reports for some very obscure cases
8860 mainly involving auth configuration (the "all modules decline to
8861 handle" case which is a sure sign of a server bug in most cases,
8862 but also happens when authentication is badly misconfigured).
8865 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
8866 it's *for*, and this sort of thing really shouldn't be cluttering
8867 up the Makefile). [Robert Thau]
8869 *) Incidental code cleanups in http_main.c --- stop dragging
8870 sa_client around; just declare it where used. [Robert Thau]
8872 *) Another acc-related fix. (It doesn't like const char
8873 in some places...). [Mark Cox]
8875 Changes with Shambhala 0.6.1 13 Jul 1995
8877 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
8878 Also, fixed auth typo in http_protocol.c unmasked by this fix.
8880 *) Compiles clean with acc on SunOS [Paul Sutton]
8882 *) Reordered modules in modules.c so that Redirect takes priority
8883 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
8884 believe it or not, he has an actual site with a ScriptAlias and
8885 a Redirect declared for the *exact same directory*. Even *my*
8886 compatibility fetish wouldn't motivate me to fix this if the fix
8887 required any effort, but it doesn't, so what the hey.
8889 *) Fixed to properly default several server_rec fields for virtual
8890 servers from the corresponding fields in the main server_rec.
8891 [Cliff Skolnick --- 'port' was a particular irritant].
8893 *) No longer kills off nph- child processes before they are
8894 finished sending output. [Matthew Gray]
8896 Changes with Shambhala 0.6.0 10 Jul 1995
8898 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
8899 the connection to the client in an "aborted" state, but otherwise
8900 allow whatever handlers are running to clean up. hard_timeout()s
8901 abort the request in progress completely; anything not tied to some
8902 resource pool cleanup will leak. They're still around because I
8903 haven't yet come up with a more elegant way of handling
8904 timeouts when talking to something that isn't the client. The
8905 default_handler and the dir_handler now use soft timeouts, largely
8906 so I can test the feature. [Robert Thau]
8908 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
8909 the case of log handlers dying prematurely is probably handled VERY
8910 gracelessly at this point, and if the logger stops reading input,
8911 the server will hang. (It is known to correctly restart the
8912 logging process on server restart; this is (should be!) going through
8913 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
8914 script). [Robert Thau]
8916 *) asis files supported (new module). [Robert Thau]
8918 *) IdentityCheck code is compiled in, but has not been tested. (I
8919 don't know anyone who runs identd). [Robert Thau]
8921 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
8922 came in with the request, for NCSA bug-compatibility. [Robert Thau]
8924 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
8926 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
8927 as timeouts are not in scope. [Robert Thau]
8929 *) quoted-string args in config files now handled correctly (doesn't drop
8930 the last character). [Robert Thau; reported by Randy Terbush]
8932 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
8933 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
8935 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
8936 default default type); the former default default behavior when all
8937 type-checkers defaulted had been a core dump. [Paul Sutton]
8939 *) Copy filenames out of the struct dirent when indexing
8940 directories. (On Linux, readdir() returns a pointer to the same
8941 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
8943 Changes with Shambhala 0.5.3 [not released]
8945 *) Default response handler notes "file not found" in the error log,
8946 if the file was not found. [Cliff Skolnick].
8948 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
8949 code no longer sets up bogus PATH_INFO which fakes out the directory
8950 handler). [Cliff Skolnick]
8952 Changes with Shambhala 0.5.2 06 Jul 1995
8954 *) Changes to http_main.c --- root server no longer plays silly
8955 games with SIGCHLD, and so now detects and replaces dying
8956 children. Child processes just die on SIGTERM, without taking
8957 the whole process group with them. Potential problem --- if any
8958 child process refuses to die, we hang in restart.
8959 MaxRequestsPerChild may still not work, but it certainly works
8960 better than it did before this! [Robert Thau]
8962 *) mod_dir.c bug fixes: ReadmeName and HeaderName
8963 work (or work better, at least); over-long description lines
8964 properly terminated. [Mark Cox]
8966 *) http_request.c now calls unescape_url() more places where it
8967 should [Paul Sutton].
8969 *) More directory handling bugs (reported by Cox)
8970 Parent Directory link is now set correctly. [Robert Thau]
8972 Changes with Shambhala 0.5.1 04 Jul 1995
8974 *) Generalized cleanup interface in alloc.c --- any function can be
8975 registered with alloc.c as a cleanup for a resource pool;
8976 tracking of files and file descriptors has been reimplemented in
8977 terms of this interface, so I can give it some sort of a test.
8980 *) More changes in alloc.c --- new cleanup_for_exec() function,
8981 which tracks down and closes all file descriptors which have been
8982 registered with the alloc.c machinery before the server exec()s a
8983 child process for CGI or <!--#exec-->. CGI children now get
8984 started with exactly three file descriptors open. Hopefully,
8985 this cures the problem Rob H. was having with overly persistent
8986 CGI connections. [Robert Thau]
8988 *) Mutual exclusion around the accept() in child_main() --- this is
8989 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
8990 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
8991 This uses fcntl(F_SETLK,...) on the error log descriptor because
8992 flock() on that descriptor won't work on systems which have BSD
8993 flock() semantics, including (I think) Linux 1.3 and Solaris.
8995 This does work on SunOS (when the server is idle, only one
8996 process in the pool is waiting on accept()); it *ought* to work
8997 on the other systems. [Robert Thau]
8999 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
9001 *) sizeof(*sa_client) bugfix from [Rob Hartill]
9003 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
9005 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
9006 be unnecessary if I go to the revised timeout-handling scheme).
9009 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
9010 string) even if none came in with the request. [Robert Thau]
9012 *) CHANGES file added to distribution ;-).
9014 Changes with Shambhala 0.4.5
9016 *) mod_dld --- early dynamic loading support [rst]
9017 *) Add wildcard content handlers for XBITHACK; default_hander now
9018 invoked with that mechanism (as a handler hanging off mod_core) [rst]
9019 *) XBITHACK supported as a wildcard content-handler, and
9020 configurable at run-time (not just at compile time, as in the
9021 "patchy server" releases) [rst]
9023 Changes with Shambhala 0.4.4 30 Jun 1995
9025 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
9026 *) Handle Addtype x/y .z [rst, reported by Cox]
9028 Changes with Shambhala 0.4.3
9030 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
9031 synonymous [rst, terbush]
9033 Changes with Shambhala 0.4.1 28 Jun 1995
9035 *) First-cut virtual host implementation; some refit in the config
9036 reading code, and log management, was necessary to support this [rst]
9037 *) Sub-pool machinery, originally added to avoid excessive storage
9038 allocation on listings of large directories (which turned out to
9039 be the problem that the 0.3 storage accounting was added to
9040 find). Subrequests and mod_dir changed to use subpools. [rst]
9041 *) More memory debugging --- free list consistency checks. [rst]
9042 *) Added err_headers to request_rec, with support elsewhere [rst]
9043 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
9045 Changes with Shambhala 0.3 19 Jun 1995
9047 *) Switch ONE_PROCESS to a runtime command-line option (-X)
9048 *) Don't compile in mod_ai_backcompat by default
9049 *) Switch name of server from Apache to Shambhala in Makefile
9050 *) Add some accounting routines to track memory usage in the pools,
9053 Changes with Shambhala 0.2
9055 *) Set DOCUMENT_ROOT CGI variable
9056 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
9057 *) Add critical section protection to handling of cleanup structures
9059 *) Significant code reorg within the server core to group related
9060 functions together [rst]
9061 *) Correctly handle clients that hang up before sending any request
9063 *) Replace dying child processes. [rst]
9065 Changes with Shambhala 0.1 12 Jun 1995
9067 Major rewrite of the pre-existing "patchy server" codebase, by
9068 Robert Thau (rst). Significant portions of the server code, such
9069 as configuration-file handling and HTTP authentication support,
9070 were ripped out and rewritten from scratch. Code that was not
9071 completely rewritten was significantly altered.
9073 Major changes with this release include:
9075 *) Introduction of the module API; in request handling, the central
9076 machinery just dispatches to various modules, which actually do
9077 most of the work. Configuration handling is similar --- modules
9078 declare their own commands, and the central machinery just
9081 API features from shambhala/0.1 were substantially unchanged in
9082 Apache 1.0 and 1.1. (1.0 API features not yet present in this
9083 release, such as wildcard handlers and subpools, were added in
9084 subsequent Shambhala releases, and were also generally rst's
9087 *) This release included the following modules:
9089 mod_access (access control --- allow and deny directives),
9090 mod_alias (Alias and Redirect commands),
9091 mod_auth (straight HTTP authentication, based on flat-files)
9092 mod_auth_dbm (same, with dbm files)
9093 mod_cgi (CGI scripts and, in this release, ScriptAlias)
9094 mod_common_log (CLF access logs; later renamed mod_log_common)
9095 mod_dir (directory indexing)
9096 mod_include (server-side includes)
9097 mod_mime (AddType directives)
9098 mod_negotiation (content negotiation)
9099 mod_userdir (support for users' public_html directories)
9101 It also included a mod_ai_backcompat, which was a private hack
9102 for back-compatibility with rst's own AI-lab servers.
9104 All of these modules were substantially complete, and functional
9105 or nearly so (a few, which implemented features not in use at
9106 Thau's site, required patches of a few lines).
9108 *) sub-request machinery, to allow modules to determine how other
9109 modules would assign MIME types to a given file, or optionally
9110 serve its content (this is heavily used by mod_dir, mod_include
9111 and mod_negotiation).
9113 *) Resource pool system for keeping track of memory allocated and
9114 files opened in service of a particular request. Much of the
9115 code in the modules (when they weren't rewrites) was adjusted to
9116 replace a pervasive convention of using fixed-size buffers on
9117 the stack with an equally pervasive convention of using memory
9118 allocated with palloc().
9120 *) Reorganization of data structures associated with a given
9121 request to eliminate use of global variables and the troublesome
9122 unmunge_name function (used in NCSA and early Apache releases to
9123 attempt to determine the URI which mapped to a given filename
9124 --- a difficult proposition, given that it is easy to produce
9125 setups in which multiple URIs map to the same file).
9127 *) Source files renamed and rearranged
9129 *) Very simple pre-forking behavior --- parent process forked off a
9130 fixed number of children, and then just waited for SIGHUP.
9132 *) Other more minor changes too numerous to list.
9134 This release included modified versions of a lot of code from the
9135 Apache 0.6.4 public release, plus an early pre-forking patch
9136 codeveloped by Robert Thau and Rob Hartill.
9138 Changes with Apache 0.7.3 20 Jun 1995
9140 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
9141 were incorporated by Rob Hartill on the main branch while Robert Thau
9142 worked on the Shambhala rewrite above. Most were merged into the
9143 Shambala architecture after Apache 0.8.0.
9145 Changes with Apache 0.6.4 13 May 1995
9147 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
9150 Changes with Apache 0.5.1 10 Apr 1995
9152 Changes with Apache 0.4 02 Apr 1995
9154 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
9157 Changes with Apache 0.3 24 Mar 1995
9159 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
9162 Changes with Apache 0.2 18 Mar 1995
9164 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
9165 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
9166 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
