1 Changes with Apache 2.0.12-dev
3 *) Rename mpmt_pthread to threaded. This is more in line with the
4 fact that mpmt_pthread shouldn't be using pthreads directly, and
5 it is a smaller name that doesn't tie into anything.
8 *) Rename the module structures so that the exported symbol matches
9 the file name, and it is easier to automate the installation
10 process (generating LoadModule directives from the module filenames).
13 *) Remove the coalesce filter. With the ap_f* functions, this filter
14 is no longer needed. [Ryan Bloom]
16 Changes with Apache 2.0.11
18 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
19 added feature of allowing a uid/gid per child process. If no
20 uid/gid is specified, then Perchild behaves exactly like dexter.
23 *) Get perchild building again. [Ryan Bloom]
25 *) Don't disable threads just because we are using the prefork MPM.
26 If somebody wants to compile without threads, they must now add
27 --disable-threads to the configure command line. [Ryan Bloom]
29 *) Begin to move the calls to update_child_status into common code, so
30 that each individual MPM does not need to update the scoreboard itself.
33 *) Allow mod_tls to compile under Unix boxes where openssl has been
34 installed to the system include files.
35 [Gomez Henri <new-httpd@slib.fr>]
37 *) Cleanup the mod_tls configure process. This should remove any need
38 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
39 configure doesn't check that yet. [Ryan Bloom]
41 *) Add a very early prototype of SSL support (in mod_tls.c). It is
42 vital that you read modules/tls/README before attempting to build
45 *) Fix a potential seg fault on all platforms. David Reid fixed this
46 on BEOS, but the problem could happen anywhere, so we don't want
47 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
49 *) Add new LogFormat directive, %D, to log time it takes to serve a
50 request in microseconds. [Bill Stoddard]
52 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
53 SetOutputFilter. This corresponds nicely with the other Set
54 directives, which operate on containers while the Add* directives
55 tend to work directly on extensions. [Ryan Bloom]
57 *) Cleanup the header handling a bit. This uses the apr_brigade_*
58 functions for the buffering so that we don't need to compute
59 the length of the headers before we actually create the header
62 *) Allow filters to buffer data using the ap_f* functions. These have
63 become macros that resolve directly to apr_brigade_*.
66 *) Get the Unix MPM's to do a graceful restart again. If we are going
67 to register a cleanup with ap_cleanup_scoreboard, then we have to
68 kill the cleanup with the same function, and that function can't be
71 *) Install all required header files. Without these, it was not
72 possible to compile some modules outside of the server.
75 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
76 forward from 1.3 to 2.0, we missed a single line, which broke regex
79 *) We have a poor abstraction in the protocol. This is a temporary
80 hack to fix the bug, but it will need to be fixed for real. If
81 we find an error while sending out a custom error response, we back
82 up to the first non-OK request and send the data. Then, when we send
83 the EOS from finalize_request_protocol, we go to the last request,
84 to ensure that we aren't sending an EOS to a request that has already
85 received one. Because the data is sent on a different request than
86 the EOS, the error text never gets sent down the filter stack. This
87 fixes the problem by finding the last request, and sending the data
88 with that request. [Ryan Bloom]
90 *) Make the server status page show the correct restart time, and
91 thus the proper uptime. [Ryan Bloom]
93 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
94 should reduce the amount of duplicate code that is required to
96 [Paul J. Reder <rederpj@raleigh.ibm.com>]
98 *) ap_new_connection() closes the socket and returns NULL if a socket
99 call fails. Usually this is due to a connection which has been
100 reset. [Jeff Trawick]
102 *) Move the Apache version information out of httpd.h and into release.h.
103 This is in preparation for the first tag with the new tag and release
106 *) Begin restructuring scoreboard code to enable adding back in
107 the ability to use IPC other than shared memory.
108 Get mod_status working on Windows again. [Bill Stoddard]
110 *) Make mod_status work with 2.0. This will work for prefork,
111 mpmt_pthread, and dexter. [Ryan Bloom]
113 *) Correct a typo in httpd.conf.
114 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
116 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
118 *) Get the correct IP address if ServerName isn't set and we can't
119 find a fully-qualified domain name at startup.
120 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
122 *) Make mod_cgid work with SuExec. [Ryan Bloom]
124 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
125 'extra' stat's for user/group since they should never occur, and now
126 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
127 volumes. [William Rowe]
129 *) Adopt apr features to simplify mod_includes. This changes the
130 behavior of the USER_NAME variable, unknown uid's are now reported
131 as USER_NAME="<unknown>" rather than the old user#000 result.
132 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
134 *) Adopt apr features for simplifing mod_userdir, and accept the new
135 Win32/OS2 exceptions without hiccuping. [William Rowe]
137 *) Replace configure --with-optim option by using and saving the
138 environment variable OPTIM instead. This is needed because configure
139 options do not support multiple flags separated by spaces.
142 *) Fix some byterange handling. If we get a byte range that looks like
143 "-999999" where that is past the end of the file, we should return
144 a PARTIAL CONTENT status code, and return the whole file as one big
145 byterange. This matches the 1.3 handling now. [Ryan Bloom]
147 *) Make the error bucket a real meta-data bucket. This means that the
148 bucket length is 0, and a read returns NULL data. If one of these
149 buckets is passed down after the headers are sent, this data will
150 just be ignored. [Greg Stein]
152 *) The prefork MPM wasn't killing child processes correctly if a restart
153 signal was received while the process was serving a request. The child
154 process would become the equivalent of a second parent process. If
155 we break out of the accept loop, then we need to do die after cleaning
156 up after ourselves. [Ryan Bloom]
158 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
159 restarts. [Ryan Bloom]
161 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
162 the most optimal APR_FINFO_wanted bits. This spares Win32 from
163 performing very expensive owner, group and permission lookups
164 and allows the server to function until these apr_finfo_t fields
165 are implemented under Win32. [William Rowe]
167 *) Support for typedsafe optional functions - that is functions exported by
168 optional modules, which, therefore, may or may not be present, depending
169 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
170 for sample code. [Ben Laurie]
172 *) filters can now report an HTTP error to the server. This is done
173 by sending a brigade where the first bucket is an error_bucket.
174 This bucket is a simple bucket that stores an HTTP error and
175 a string. Currently the string is not used, but it may be needed
176 to output an error log. The http_header_filter will find this
177 bucket, and output the error text, and then return
178 AP_FILTER_ERROR, which informs the server that the error web page
179 has already been sent. [Ryan Bloom]
181 *) If we get an error, then we should remove all filters except for
182 those critical to serving a web page. This fixes a bug, where
183 error pages were going through the byterange filter, even though
184 that made no sense. [Ryan Bloom]
186 *) Relax the syntax checking of Host: headers in order to support
187 iDNS. PR#6635 [Tony Finch]
189 *) Cleanup the byterange filter to use the apr_brigade_partition
190 and apr_bucket_copy functions. This removes a lot of very messy
191 code, and hopefully makes this filter more stable.
194 *) Remove AddModule and ClearModuleList directives. Both of these
195 directives were used to ensure that modules could be enabled
196 in the correct order. That requirement is now gone, because
197 we use hooks to ensure that modules are in the correct order.
200 *) When SuExec is specified, we need to add it to the list of
201 targets to be built. If we don't, then any changes to the
202 configuration won't affect SuExec, unless 'make suexec' is
203 specifically run. [Ryan Bloom]
205 *) Cleaned out open_file from mod_file_cache, as apr now accepts
206 the APR_XTHREAD argument to open a file for consumption by
207 parallel threads on win32. [William Rowe]
209 *) Correct a bug in determining when we follow symlinks. The code
210 expected a stat -1 result, not an apr_status_t positive error.
211 Also check if the APR_FINFO_USER fields are valid before we
212 follow the link. [William Rowe]
214 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
215 mpm_common.c. These functions are only valid on some platforms,
216 so they should not be in the main-line code. [Ryan Bloom]
218 *) Remove ap_chdir_file(). This function is not thread-safe,
219 and nobody is currently using it. [Ryan Bloom]
221 *) Do not try to run make depend if there are no .c files in the
222 current directory, doing so makes `make depend` fail.
225 *) Update highperformance.conf to work with either prefork or
226 pthreads mpms. [Greg Ames]
228 *) Stop checking to see if this is a pipelined request if we know
229 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
230 This keeps us from making an extra read call when serving a 1.0
231 request. [Ryan Bloom and Greg Stein]
233 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
234 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
235 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
237 *) Fix the RFC number mentioned when complaining about a missing
238 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
240 *) Fix an endless loop in ab which occurred when ab was posting
241 and the server dropped the connection unexpectedly.
244 *) Fix a segfault while handling request bodies in ap_http_filter().
245 This problem has been seen with mod_dav usage as well as with
246 requests where the body was just being discarded. [Jeff Trawick]
248 *) Some adjustment on the handling and automatic setting (via
249 hints.m4) of various compilation flags (eg: CFLAGS). Also,
250 add the capability to specify flags (NOTEST_CFLAGS and
251 NOTEST_LDFLAGS) which are used to compile Apache, but
252 not used during the configuration process. Useful for
253 flags like "-Werror". [Jim Jagielski]
255 *) Stop using environment variables to force debug mode or
256 no detach. We now use the -D command line argument to
257 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
258 [Greg Stein, Ryan Bloom]
260 *) Change handlers to use hooks. [Ben Laurie]
262 *) Stop returning copies of filenames from both apr_file_t and
263 apr_dir_t. We pstrdup the filenames that we store in the
264 actual structures, so we don't need to pstrdup the strings again.
267 *) mod_cgi: Fix some problems where the wrong error value was being
268 traced. [Jeff Trawick]
270 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
273 *) Add generic hooks. [Ben Laurie]
275 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
277 *) Fix a segfault caused by mod_ext_filter when the external filter
278 program does not exist. [Jeff Trawick]
280 *) Fix an output truncation error when on an HTTP >= 1.0 request an
281 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
282 was served through mod_charset_lite (or anything else that would
283 create a transient bucket in this size range). ap_bucket_make_heap()
284 silently failed (fixed), transient_setaside() discovered it, but
285 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
287 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
288 is that some browsers send extra lines at the end of POST requests, and
289 we don't want to delay sending data back to the user just because the
290 browser isn't well behaved. [Ryan Bloom]
292 *) Get SuEXEC working again. We can't send absolute paths to suExec
293 because it refuses to execute those programs. SuEXEC also wasn't
294 always recognizing configuration changes made using the autoconf
297 *) Allow the buildconf process to find the config.m4 files in the correct
298 order. Basically, we can now name config.m4 files as config\d\d.m4,
299 and we will sort them correctly when inserting them into the build
300 process. [Ryan Bloom]
302 *) Get mod_cgid to use apr calls for creating the actual CGI process.
303 This also allows mod_cgid to use ap_os_create_priviledged_process,
304 thus allowing for SuExec execution from mod_cgid. Currently, we do
305 not support everything that standard SuExec supports, but at least
306 it works minimally now. [Ryan Bloom]
308 *) Allow SuExec to be configured from the ./configure command line.
311 *) Update some of the docs in README and INSTALL to reflect some of
312 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
314 *) If we get EAGAIN returned from the call to apr_sendfile, then we
315 need to call sendfile again. This gets us serving large files
316 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
318 *) Get the support programs building cleanly again.
319 [Cliff Woolley <cliffwoolley@yahoo.com>]
321 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
322 current directory logic now backs up over bin/ to determine the
323 server root from the Apache.exe path.
325 *) Apache/Win32 now follows the standard conventions of mod_foo.so
326 loadable modules, dynamic libs are all named libfoo.dll, and the
327 makefile.win populates the include, lib and libexec directories.
329 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
330 Apache gets IPv6 listening sockets by default. Additionally, the
331 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
332 numeric address strings (e.g., "Listen [fe80::1]:8080").
335 *) Modify the install directory layout. Modules are now installed in
336 modules/. Shared libraries should be installed in libraries/, but
337 we don't have any of those on Unix yet. All install directories
338 are modifyable at configure time. [Ryan Bloom]
340 *) Install all header files in the same directory on Unix. [Ryan Bloom]
342 *) Get the functions in server/linked into the server, regardless of
343 which modules linked into the server. This uses the same hack
344 for Apache that we use for APR and apr-util to ensure all of the
345 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
346 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
347 the scripts a bit easier.
350 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
351 on the query, and remove IPv4 dependencies. [Jeff Trawick]
353 *) Get all of the auth modules to the point that they will install and
354 be loadable into the server. Our new build/install mechanism expects
355 that all modules will have a common name format. The auth modules
356 didn't use that format, so we didn't install them properly.
359 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
360 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
362 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
364 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
365 after the end of the response. [Ryan Bloom]
367 *) Get byterange requests working with responses that do not have a
368 content-length. Because of the way byterange requests work, we have to
369 have all of the data before we can actually do the byterange, so we
370 can compute the content-length in the byterange filter.
373 *) Get exe CGI's working again on Windows.
376 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
377 they keep track of whether or not their post config hook has been
378 called before. Instead of a static variable (which is replaced when
379 the DSO is loaded a second time), use userdata in the process pool.
382 Changes with Apache 2.0a9
384 *) Win32 now requires perl to complete the final install step for users
385 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
386 and installs the conf, htdocs and htdocs/manual directories.
389 *) Make mod_include use a hash table to associate directive tags with
390 functions. This allows modules to implement their own SSI tags easily.
391 The idea is simple enough, a module can insert it's own tag and function
392 combination into a hash table provided by mod_include. While mod_include
393 parses an SSI file, when it encounters a tag in the file, it does a
394 hash lookup to find the function that implements that tag, and passes
395 all of the relevant data to the function. That function is then
396 responsible for processing the tag and handing the remaining data back
397 to mod_include for further processing.
398 [Paul J. Reder <rederpj@raleigh.ibm.com>]
400 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
401 fewer parameters: the local and remote socket addresses were removed
402 from the parameter list because all required information is available
403 via the APR socket. [Jeff Trawick]
405 *) Distribution directory structure reorganized to reflect a
406 normal source distribution with external install targets.
409 *) The MPMs that need multiple segments of shared memory now create
410 two apr_shmem_t variables, one for each shared memory allocation.
411 the problem is that we can't determine how much memory will be required
412 for shared memory allocations once we try to allocate more than one
413 variable. The MM code automatically aligns the shared memory allocations,
414 so we end up needing to pad the amount of shared memory we want based
415 on how many variables will be allocated out of the shared memory segment.
416 It is just easier to create a second apr_shmem_t variable, and two
420 *) Cleanup the export list a bit. This creates a single unified list of
421 functions exported by APR. The export list is generated at configure
422 time, and that list is then used to generate the exports.c file.
423 Because of the way the export list is generated, we only export those
424 functions that are valid on the platform we are building on.
427 *) Enable logging the cookie with mod_log_config
428 [Sander van Zoest <sander@covalent.net>]
430 *) Fix a segfault in mod_info when it reaches the end of the configuration.
433 *) Added lib/aputil/ as a placeholder for utility functions which are not
434 specific to the Apache HTTP Server (but do not make sense with APR).
435 The first utility is "apu_dbm": a set of functions to work with DBM
436 files. This first version can be compiled for SDBM or GDBM databases.
439 *) Complete re-write of mod_include. This makes mod_include a filter that
440 uses buckets directly. This has now served the FAQ correctly.
441 [Paul Reder <rederpj@raleigh.ibm.com>]
443 *) Allow modules to specify the first filter in a sub_request when
444 making the sub_request. This keeps modules from having to change the
445 output_filter immediately after creating the sub-request, and therefore
446 skip the sub_req_output_filter. [Ryan Bloom]
448 *) Update ab to accept URLs with IPv6 literal address strings (in the
449 format described in RFC 2732), and to build Host header fields in
450 the same format. This allows IPv6 literal address strings to be
451 used with ab. This support has been tested against Apache 1.3 with
452 the KAME patch, but Apache 2.0 does not yet work with this format
453 of the Host header field. [Jeff Trawick]
455 *) Accomodate an out-of-space condition in the piped logs and the
456 rotatelogs.c code, and no longer churn log processes for this
457 condition. [Victor J. Orlikowski]
459 *) Add support for partial writes with apr_sendfile() to core_output_filter.
462 Changes with Apache 2.0a8
464 *) Add a directive to mod_mime so that filters can be associated with
468 *) Get multi-views working again. We were setting the path_info
469 field incorrectly if we couldn't find the specified file.
472 *) Fix 304 processing. The core should never try to send the headers
473 down the filter stack. Always, just setup the table in the request
474 record, and let the header filter convert it to data that is ready
478 *) More fixes for the proxy. There are still bugs in the proxy code,
479 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
483 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
486 *) APR: Add new apr_getopt_long function to handle long options.
487 [B. W. Fitzpatrick <fitz@red-bean.com>]
489 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
490 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
491 hostname resolution/address string parsing and building
492 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
493 of one of the apr_sockaddr_t structures for a socket. Change
494 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
496 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
497 I have proxied pages with it, cleanup will commence soon.
500 *) Make the proxy work with filters. This isn't perfect, because we
501 aren't dealing with the headers properly. [Ryan Bloom]
503 *) Do not send a content-length iff the C-L is 0 and this is a head
504 request. [Ryan Bloom]
506 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
507 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
509 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
511 *) Get the default_handler to stop trying to deal with HEAD requests.
512 The idea is to let the content-length filter compute the C-L before
513 we try to send the data. If we can get the C-L correctly, then we
514 should send it in the HEAD response.
517 *) The Header filter can now determine if a body should be sent based
518 on r->header_only. The general idea of this is that if we delay
519 deciding to send the body, then we might be able to compute the
520 content-length correctly, which will help caching proxies to cache
521 our data better. Any handler that doesn't want to try to compute
522 the content-length can just send an EOS bucket without data and
523 everything will just work.
526 *) Add the referer to the error log if one is available.
527 [Markus Gyger <mgyger@itr.ch>]
529 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
530 change, the root of the configuration tree has been exposed to modules
532 [Ryan Morgan <rmorgan@covalent.net>]
534 *) Get the core_output_filter to use the bucket interface directly.
535 This keeps us from calling the content-length filter multiple times
536 for a simple static request.
539 *) We are sending the content-type correctly now.
540 [Ryan Bloom and Will Rowe]
542 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
543 a bogus bytes-sent value when the only thing being sent was trailers
544 and writev() returned an error (or EAGAIN). [Jeff Trawick]
546 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
547 hints file to determine which platforms define
548 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
551 *) APR: add apr_get_home_directory() [Jeff Trawick]
553 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
555 *) Not all platforms have INADDR_NONE defined by default. Apache
556 used to make this check and define INADDR_NONE if appropriate,
557 but APR needs the check too, and I suspect other applications will
558 as well. APR now defines APR_INADDR_NONE, which is always a valid
559 value on all platforms.
560 [Branko Èibej <brane@xbc.nu>]
562 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
563 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
565 *) Relax the syntax checking of Host: headers in order to support
566 iDNS. PR#6635 [Tony Finch]
568 *) When reading from file buckets we convert to an MMAP if it makes
569 sense. This also simplifies the default handler because the
570 default handler no longer needs to try to create MMAPs.
573 *) BUFF has been removed from the main server. The BUFF code will remain
574 in the code until it has been purged from the proxy module as well.
577 *) Byteranges have been completely re-written to be a filter. This
578 has been tested, and I believe it is working correctly, but it could
579 doesn't work for the Adobe Acrobat plug-in. The output almost matches
580 the output from 1.3, the only difference being that 1.3 includes
581 a content-length in the response, and this does not.
584 *) APR read/write functions and bucket read functions now operate
585 on unsigned integers, instead of signed ones. It doesn't make
586 any sense to use signed ints, because we return the error codes,
587 so if we have an error we should report 0 bytes read or written.
590 *) Always compute the content length, whether it is sent or not.
591 The reason for this, is that it allows us to correctly report
592 the bytes_sent when logging the request. This also simplifies
593 content-length filter a bit, and fixes the actual byte-reporing
594 code in mod_log_config.c
597 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
598 it says, because it was only used by EOS and FLUSH buckets. Since
599 neither of those are required at the end of a brigade, this was
600 really signifying FLUSH_THE_DATA, but that can be determined better
601 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
602 buckets now return a length of 0, which is actually the amount of data
603 read, so they make more sense.
606 *) Allow the core_output_filter to save some data past the end of a
607 request. If we get an EOS bucket, we only send the data if it
608 makes sense to send it. This allows us to pipeline request
609 responses. As a part of this, we also need to allocate mmap
610 buckets out of the connection pool, not the request pool. This
611 allows the mmap to outlive the request.
614 *) Make blocking and non-blocking bucket reads work correctly for
615 sockets and pipes. These are the only bucket types that should
616 have non-blocking reads, because the other bucket types should
617 ALWAYS be able to return something immediately.
620 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
621 server, but use Ctrl+Break to initiate a graceful restart
622 instead of duplicating behavior. [John Sterling]
624 *) Patch mod_autoindex to set the Last-Modified header based on
625 the directory's mtime, and add the ETag header. [William Rowe]
627 *) Merge the 1.3 patch to add support for logging query string in
628 such a way that "%m %U%q %H" is the same as "%r".
631 *) Port three log methods from mod_log_config 1.3 to 2.0:
632 CLF compliant '-' byte count, method and protocol.
635 *) Add a new LogFormat directive, %c, that will log connection
636 status at the end of the response as follows:
637 'X' - connection aborted before the response completed.
638 '+' - connection may be kept-alive by the server.
639 '-' - connection will be closed by the server.
642 *) Expand APR for WinNT to fully accept and return utf-8 encoded
643 Unicode file names and paths for Win32, and tag the Content-Type
644 from mod_autoindex to reflect that charset if the the feature
645 macro APR_HAS_UNICODE_FS is true. [William Rowe]
647 *) Compute the content length (and add appropriate header field) for
648 the response when no content length is available and we can't use
649 chunked encoding. [Jeff Trawick]
651 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
652 so that content input filters get dechunked data when using
653 the default handler. Also removed REQUEST_CHUNKED_PASS.
656 *) Add mod_ext_filter as an experimental module. This module allows
657 the administrator to use external programs as filters. Currently,
658 only filtering of output is supported. [Jeff Trawick]
660 *) Most Apache functions work on EBCDIC machines again, as protocol
661 data is now translated (again). [Jeff Trawick]
663 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
664 the EBCDIC support. They are noops on ASCII machines, so this
665 type of translation doesn't have to be surrounded by #ifdef
666 CHARSET_EBCDIC. [Jeff Trawick]
668 *) Fix mod_include. tag commands work again, and the server will
669 send the FAQ again. This also allows mod_include to set aside
670 buckets that include partial buckets.
671 [Ryan Bloom and David Reid]
673 *) Add suexec support back. [Manoj Kasichainula]
675 *) Lingering close now uses the socket directly instead of using
676 BUFF. This has been tested, but since all we can tell is that it
677 doesn't fail, this needs to be really hacked on.
680 *) Allow filters to modify headers and have those headers be sent to
681 the client. The idea is that we have an http_header filter that
682 actually sends the headers to the network. This removes the need
683 for the BUFF to send headers.
686 *) Charset translation: mod_charset_lite handles translation of
687 request bodies. Get rid of the xlate version of ap_md5_digest()
688 since we don't compute digests of filtered (e.g., translated)
689 response bodies this way anymore. (Note that we don't do it at
690 all at the present; somebody needs to write a filter to do so.)
693 *) Input filters and ap_get_brigade() now have a input mode parameter
694 (blocking, non-blocking, peek) instead of a length parameter.
697 *) Update the mime.types file to the registered media types as
698 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
701 *) Namespace protect some macros declared in ap_config.h
704 *) Support HTTP header line folding with input filtering.
707 *) Mod_include works again. This should still be re-written, but at
708 least now we can serve an SHTML page again.
711 *) Begin to remove BUFF from the core. Currently, we keep a pointer
712 to both the BUFF and the socket in the conn_rec. Functions that
713 want to use the BUFF can, functions that want to use the socket,
714 can. They point to the same place.
717 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
718 [Tomas "Ögren" <stric@ing.umu.se>]
720 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
721 associated pool goes away. (APR pipes on OS/2 were already had this
722 logic.) This resolvs a fatal file descriptor leak with CGIs.
725 *) The final line of the config file was not being read if there was
726 no \n at the end of it. This was caused by apr_fgets returning
727 APR_EOF even though we had read valid data. This is solved by
728 making cfg_getline check the buff that was returned from apr_fgets.
729 If apr_fgets return APR_EOF, but there was data in the buf, then we
730 return the buf, otherwise we return NULL.
733 *) Piped logs work again in the 2.0 series.
736 *) Restore functionality broken by the mod_rewrite security fix:
737 rewrite map lookup keys and default values are now expanded
738 so that the lookup can depend on the requested URI etc.
739 PR #6671 [Tony Finch]
741 *) Tighten up the syntax checking of Host: headers to fix a
742 security bug in some mass virtual hosting configurations
743 that can allow a remote attacker to retrieve some files
744 on the system that should be inaccessible. [Tony Finch]
746 *) Add a pool bucket type. This bucket is used for data allocated out
747 of a pool. If the pool is cleaned before the bucket is destroyed, then
748 the data is converted to a heap bucket, allowing it to survive the
752 *) Add a flush bucket. This allows modules to signal that the filters
753 should all flush whatever data they currently have. There is no way
754 to actually force them to do this, so if a filter ignores this bucket,
755 that's life, but at least we can try with this.
758 *) Add an output filter for sub-requests. This filter just strips the
759 EOS bucket so that we don't confuse the main request's core output
760 filter by sending multiple EOS buckets. This change also makes sub
761 requests start to send EOS buckets when they are finished.
764 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
765 makes ap_bucket_destroy a return void, which is okay because it
766 used to always return APR_SUCCESS, and nobody ever checked its
768 [Cliff Woolley <cliffwoolley@yahoo.com>]
770 *) Remove the index into the bucket-type table from the buckets
771 structure. This has now been replaced with a pointer to the
772 bucket_type. Also add some macros to test the bucket-type.
775 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
776 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
777 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
778 All _VAR_ flavors changes to _DATA to be absolutely clear.
781 *) Add support for /, //, //servername and //server/sharename
782 parsing of <Directory> blocks under Win32 and OS2.
783 [Tim Costello, William Rowe, Brian Harvard]
785 *) Remove the function pointers from the ap_bucket type. They have been
786 replaced with a global table. Modules are allowed to register bucket
787 types and use then use those buckets.
790 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
791 once we finish writing the request body to the cgi child process;
792 otherwise, the client doesn't hit EOF on stdin. Small request bodies
793 worked without this change (for reasons I don't understand), but large
794 ones didn't. [Jeff Trawick]
796 *) Remove file bucket specific information from the ap_bucket type.
797 This has been moved to a file_bucket specific type that hangs off
798 the data pointer in the ap_bucket type.
801 *) Input filtering now has a third argument. This is the amount of data
802 to read from lower filters. This argument can be -1, 0, or a positive
803 number. -1 means give me all the data you have, I'll deal with it and
804 let you know if I need more. 0 means give me one line and one line
805 only. A positive number means I want no more than this much data.
807 Currently, only 0 and a positive number are implemented. This allows
808 us to remove the remaining field from the conn_rec structure, which
812 *) Big cleanup of the input filtering. The goal is that http_filter
813 understands two conditions, headers and body. It knows where it is
814 based on c->remaining. If c->remaining is 0, then we are in headers,
815 and http_filter returns a line at a time. If it is not 0, then we are
816 in body, and http_filter returns raw data, but only up to c->remaining
817 bytes. It can return less, but never more.
818 [Greg Ames, Ryan Bloom, Jeff Trawick]
820 *) mod_cgi: Write all of the request body to the child, not just what
821 the kernel would accept on the first write. [Jeff Trawick]
823 *) Back out the change that moved the brigade from the core_output_filters
824 ctx to the conn_rec. Since all requests over a given connection
825 go through the same core_output_filter, the ctx pointer has the
829 *) Fix another bug in the send_the_file() read/write loop. A partial
830 send by apr_send would cause unsent data in the read buffer to
831 get clobbered. Complete making send_the_file handle partial
832 writes to the network.
835 *) Fix a couple of type fixes to allow compilation on AIX again
836 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
838 *) Fix bug in send_the_file() which causes offset to be ignored
839 if there are no headers to send.
842 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
843 filter. Useful for supporting Windows 9* with a binary
844 compiled on Windows NT.
847 Changes with Apache 2.0a7
849 *) Reimplement core_output_filter to buffer/save bucket brigades
850 across multiple calls to the core_filter. The brigade will be
851 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
852 thresholds are hit or the EOS bucket is received.
855 *) Create experimental filter (buffer_filter) that coalesces bytes
856 into one large buffer before invoking the next filter in the
857 chain. This filter is particularly useful with the current
858 implementation of mod_autoindex when it inserted above the
859 chunk_filter. mod_autoindex generates a lot of brigades that
860 containing buckets holding just a few bytes each. The
861 buffer_filter coalesces these buckets into a single large bucket.
864 *) Add apr_sendfile() support into the core_output_filter.
867 *) Add apr_sendv() support into the core_output_filter.
870 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
871 [Mike Abbott <mja@sgi.com>]
873 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
874 make much sense, because Apache uses buckets instead of BUFFs now.
877 *) send_the_file now falls back to a read/write loop on platforms that
878 do not have sendfile.
879 [Ryan Bloom and Brian Havard]
881 *) Install apachectl correctly, and substitute the proper values so
882 that it works again. [Ryan Bloom]
884 *) Better(??) handle platforms that lack sendfile().
887 *) APR now has UUID generation/formatting/parsing support.
890 *) Begin the http_filter. This is an input filter that understands
891 the absolute basic amount required to parse an HTTP Request. The
892 goal is to be able to split headers from request body before passing
893 the data back to the other filters.
896 *) Bring forward from 1.3.13 the config directory implementation
899 *) install apxs if it is created
902 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
903 conversions. [William Rowe]
905 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
906 ap_add_output_filter(). [Jeff Trawick]
908 *) Multiple build and configuration fixes
911 -add datadir and localstatedir substitutions
913 -fix logfilename misspelling
914 -fix evaluation of installation dir variables and
915 -replace $foobar by $(foobar) to be usefull in the makefile
919 -add rules for cross-compiling in rules.mk. Okay, rule to check for
920 $CC_FOR_BUILD is still missing
921 -use CHECK_TOOL instead of CHECK_PROG for ranlib
922 -add missing "AR=@AR@" to severaly Makefile.in's
923 -cache result for "struct rlimit"
924 -compile all helper programs with native and cross compiler
925 and use the native version to generate header file
926 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
928 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
930 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
932 *) Fix a bug where a client which only sends \n to delimit header
933 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
934 message. Start working on ebcdic co-existance with input
936 [William Rowe, Greg Ames]
938 *) If mod_so is enabled in the server always create libexec, even
939 if there are no modules installed in this directory. This is a
940 requirement for APXS to work correctly.
943 *) Connection oriented output filters are now stored in the
944 conn_rec instead of the request_rec. This allows us to add the
945 output filter in the pre-connection phase instead of the
946 post_read_request phase, which keeps us from trying to write an
947 error page before we have a filter to write to the network.
948 [Ryan Bloom, Jeff Trawick, and Greg Ames]
950 *) Cleaning up an mmap bucket no longer deletes the mmap. An
951 mmap can be used across multiple buckets (default_handler with
952 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
953 the mmap itself can't be associated with the bucket.
956 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
959 *) Radical surgery to improve mod_isapi support under Win32.
960 Includes a number of newer ServerSupportFunction calls, support
961 for ReadClient (in order to retrieve POSTs greater than 48KB),
962 and general bug fixes to more reliably load ISAPI .dll's and
963 prevent leaking handle resources. Note: There are still
964 discrepancies between IIS's and Apache's ServerVariables, and
965 async calls are still not supported. Additional warnings are
966 logged to facilitate debugging of unsupported ISAPI calls.
969 *) Add input filtering to Apache. The basic idea for the input
970 filters is the same as the ideas for output filters. The biggest
971 difference is that instead of calling ap_pass_brigade, ap_get_brigade
972 should be called, and the order of execution for the filter itself is
973 different. When writing an output filter, a brigade is passed in,
974 and filters operate directly on that brigade, when done, they call
975 ap_pass_brigade. Input filters are the exact opposite. Because input
976 is not a push operation, filters first call ap_get_brigade. When this
977 function returns, the input filter will be left with a valid brigade.
978 The input filter should then operate on the brigade, and return.
981 *) Fix building on BSD/OS using its native make. The build system
982 falls back to the BSD .include directive on that host platform.
985 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
986 SHA1 and plaintext password encodings. Make feature tests a
987 bit more flexible. [William Rowe]
989 *) Charset translation: mod_charset_lite handles output content
990 translation in a filter. mod_charset_lite no longer ignores
991 subrequests. A bunch of cruft related to BUFF's support for
992 translating request and response bodies was removed.
995 *) Move the addition of the CORE filter to the post_read_request
996 hook in http_core.c. This removes the need to add the filter in
997 multiple places and allows for an SSL module to be added much
998 simpler. [Ryan Bloom]
1000 *) Fix a security problem that affects certain configurations of
1001 mod_rewrite. If the result of a RewriteRule is a filename that
1002 contains expansion specifiers, especially regexp backreferences
1003 $0..$9 and %0..%9, then it may be possible for an attacker to
1004 access any file on the web server. [Tony Finch]
1006 *) Fix a bug where errors that are detected during early request parsing
1007 don't produce visible HTTP error messages at the browser, because
1008 the core_filter wasn't present. [Greg Ames]
1010 *) Provide apr_socklen_t as a portability aid.
1011 [Victor J. Orlikowski]
1013 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
1014 as well as a comment arg to the add, adduser and update cmds.
1015 update allows the user to clear or preserve pw/groups/comment.
1016 Fixed a bug in dbmmanage that prevented the check option from
1017 parsing a password followed by :group... text. Corrected the
1018 seed calcualation for Win32 systems, and added -lsdbm support.
1021 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
1024 *) Avoid a segfault when parsing .htaccess files. An
1025 uninitialized tree pointer was passed to ap_build_config().
1028 *) Change the way that inet_addr & inet_network are checked for
1029 in APR's configure process to allow BeOS BONE to correctly
1030 find them. With this change BeOS BONE now builds from source
1031 with no problems. [David Reid]
1033 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
1034 the end of the parameters to execve() was stored in the wrong
1035 location, overlaying the storage beyond the newargs[] array and
1036 also passing uninitialized storage to execve(), which would
1037 sometimes fail with EFAULT. [Jeff Trawick]
1039 *) Fix a bug parsing configuration file containers. With a sequence
1040 like this in the config file
1042 <IfModule mod_kilroy.c>
1045 <IfModule mod_lovejoy.c>
1050 the second container would be terminated at the blank line due to
1051 sediment in the buffer from reading the prior </IfModule> and an
1052 error message would be generated for the real </IfModule> for the
1053 second container. Also due to this problem, any two characters
1054 could be used for "</" in the close of a container.
1057 *) ap_add_filter prototype changed to remove the ctx pointer. The
1058 pointer still remains in the filter structure, but it can not be
1059 a part of the ap_add_filter prototype. The reason is that when
1060 the core uses AddFilter to add a filter to the stack it doesn't
1061 know how to allocate the ctx pointer, or even how much memory should
1062 be allocated. The filters will have to be responsible for allocating
1063 the ctx memory when they need it.
1066 *) Add an AddFilter directive. This directive takes a list of filters
1067 that should be activated for the requested resource.
1070 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
1071 some other platforms). [Jeff Trawick]
1073 *) Modify mod_include to be a filter. Currently, it has only been tested
1074 on actual files, but it should work for CGI scripts too.
1077 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
1078 writes. apr_flush() for Unix: handle interrupted writes.
1081 *) NameVirtualHost can now take "*" as an argument instead of
1082 an IP address. This allows you to create a purely name-based
1083 virtual hosting server that does not have any IP addresses in
1084 the configuration file and which ignores the local address
1085 of any connections. PR #5595, PR #4455 [Tony Finch]
1087 *) Fix some compile warnings in mod_mmap_static.c
1088 [Mike Abbott <mja@sgi.com>]
1090 *) Fix chunking problem with CGI scripts. The general problem was that
1091 the CGI modules were adding an EOS bucket and then the core added an
1092 EOS bucket. The chunking filter finalizes the chunked response when it
1093 encounters an EOS bucket. Because two EOS buckets were sent, we
1094 finalized the response twice. The fix is to make sure we only send one
1095 EOS, by utilizing a flag in the request_rec.
1098 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
1099 and Win32. Previously, the first read from an apr_file_t set up via
1100 apr_put_os_file() would return a '\0'. [Jeff Trawick]
1102 *) Mod_cgid now creates a single element bucket brigade, with a pipe
1103 bucket, instead of using BUFF's and ap_r*.
1106 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
1107 [Mike Abbott <mja@sgi.com>]
1109 *) Remove ap_bopenf from buff code. This required modifying the file_cache
1110 code to use APR file's directly instead of going through BUFFs.
1113 *) Fix compile break on some platforms for mod_mime_magic.c
1114 [John K. Sterling <sterling@covalent.net>]
1116 *) Fix merging of AddDefaultCharset directive.
1117 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
1119 *) Minor revamp of the rlimit sections of code. We now test
1120 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
1121 is now "available" even if the platform doesn't support
1122 the rlimit family (it's just a noop though). [Jim Jagielski]
1124 *) Migrate the pre-selection of which MPM to use for specific
1125 platforms to hints.m4, which contains (or should contain)
1126 all platform specific "hints". [Jim Jagielski]
1128 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
1131 *) Add tables with non-string/binary values to APR.
1134 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
1137 *) Update PCRE to version 3.2. [Ryan Bloom]
1139 *) Change the way buckets' destroy functions are called so that
1140 they can be more directly used when changing the type of a
1141 bucket in place. [Tony Finch]
1143 *) Add generic support for reference-counting the resources used by
1144 buckets, and alter the HEAP and MMAP buckets to use it. Change
1145 the way buckets are initialised to support changing the type of
1146 buckets in place, and use it when setting aside TRANSIENT buckets.
1147 Change the implementation of TRANSIENT buckets so that it can be
1148 mostly shared with IMMORTAL buckets, which are now implemented.
1151 Changes with Apache 2.0a6
1153 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
1155 *) Add a chunking filter to Apache. This brings us one step closer
1156 to removing BUFF. [Ryan Bloom]
1158 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
1159 added to the stack is the last filter to be called. [Ryan Bloom]
1161 *) Apache 2.0 has been completely documented using Scandoc. The
1162 docs can be generated by running 'make docs'. [Ryan Bloom]
1164 *) Add filtered I/O to Apache. This is based on bucket brigades,
1165 Currently the buckets still use BUFF under the covers, but that
1166 should change quickly. The only currently written filter is the
1167 core filter which just calls ap_bwrite. [The Apache Group]
1169 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
1170 built with thread support. [Jeff Trawick]
1172 *) Abort configuration if --with-layout was specified and there's
1173 no layout definition file. [Ken Coar]
1175 *) Add support for '--with-port=n' option to configure. [Ken Coar]
1177 *) Add support for extension methods for the Allow response header
1178 field, and an API routine for accessing r->allowed and the
1179 list of extension methods in a unified manner. [Ken Coar]
1181 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
1182 [Rob Simonson <simo@us.ibm.com>]
1184 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
1185 APACHE_XLATE builds. [Jeff Trawick]
1187 *) A configuration file parsing problem was fixed. When the
1188 configuration file started with an IfModule/IfDefine container,
1189 only the last statement in the container would be retained.
1192 Changes with Apache 2.0a5
1194 *) Perchild is serving pages after passing them to different child
1195 processes. There are still a lot of bugs, but this does work. I
1196 have made requests against the same installation of Apache, and had
1197 different servers use different user IDs to serve the responses.
1198 This change moves to using socketpair instead of an AF_UNIX socket.
1201 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
1202 It can't seem to pass between child processes yet, but I think we
1203 are closer now than before. This moves us back to using Unix
1204 Domain Sockets. [Ryan Bloom]
1206 *) libapr functions and types renamed with apr_ prefix.
1207 #include "apr_compat.h" for 1.3.x backwards compat
1210 *) Fix problems with APR sockaddr handling on Win32. It didn't always
1211 return the right information on the local socket address.

1214 *) ap_recv() on Win32: Set bytes-read to 0 on error.
1215 [Gregory Nicholls <gnicholls@level8.com>]
1217 *) Add an option to not detach from the controlling terminal without
1218 going into single process mode. This allows for much easier
1219 debugging of the process startup code. [Ryan Bloom]
1221 *) ab: don't use perror() to report the failure of an APR function.
1224 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
1225 scoreboard on graceful restarts.
1228 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
1229 An invalid ap_proc_t was passed to ap_create_process().
1232 *) Allow modules to register filters. Those filters are still
1233 never called, but this is a step in the right direction.
1234 [Ryan Bloom and Greg Stein]
1236 *) Register the mod_cgid daemon process for cleanup so that it is
1237 killed at termination if it does not die when the parent gets
1238 SIGTERM. This change is to fix occasional problems where the
1239 process stays around. Bugs in similar logic in mod_rewrite and
1240 mod_include were also fixed. [Jeff Trawick]
1242 *) Fix a bug in the time handling. Basically, we were imploding a time
1243 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
1244 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
1245 uses those two fields to adjust the time value. Because of the HTTP
1246 spec, both of those values can be zero'ed out safely. This fixes
1247 the bug correctly. [Ryan Bloom]
1249 *) Fix a couple of place in the Windows code where the wrong error
1250 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
1252 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
1254 *) Added the APR_EOL_STR macro for platform dependent differences in
1255 logfiles and other raw text (such as all APR files). Fixes logfiles
1256 not terminated with cr/lf sequences in Win32. [William Rowe]
1258 *) Move all strings functions in APR to src/lib/apr/strings and create
1259 apr_strings.h for the prototypes. [Ryan Bloom]
1261 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
1262 to repeat the syscall until we stop getting EINTR. I noticed a
1263 related problem at termination (SIGTERM) on FreeBSD when using
1264 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
1265 implementation work properly with child init. Previously, ap_lock()
1266 was essentially a no-op because all children were using different
1267 locks and thus nobody ever blocked. [Jeff Trawick]
1269 *) The htdocs/ tree has been moved out of the CVS source tree into
1270 a separate area for easier development. This has NO EFFECT on
1271 end-users or Apache installations. [Ken Coar]
1273 *) Integrate the mod_dav module for WebDAV protocol handling. This
1274 adds the dav and dav_fs modules, the SDBM library, and additional
1275 XML handling utilities. [Greg Stein]
1277 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
1280 *) Update the lib/expat-lite/ library (bring forward changes from
1281 the Apache 1.3 repository). [Greg Stein]
1283 *) If sizeof(long long) == sizeof(long), then prefer long in APR
1284 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
1286 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
1287 machines where sendfile is detected, but nobody has written ap_sendfile.
1288 [Dave Hill <ddhill@zk3.dec.com>]
1290 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
1292 *) ab would start up more connections than needed, then quit when the
1293 desired number were finished. Also fixed a logic error involving
1294 ab keepalives. [Victor J. Orlikowski]
1296 *) WinNT: Implement non-blocking pipes with timeouts to communicate
1297 with CGIs. Apache 2.0a4 had non-blocking pipes but without
1298 timeouts (i.e, if a timeout was specified, the pipe reverted to
1299 a full blocking pipe). Now the behaviour is more in line with
1300 Unix non-blocking pipes.
1303 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
1304 cache open file handles along with accept socket reuse enables
1305 Apache 2.0 to serve non-keepalive requests for static files at
1306 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
1307 and Apache 2.0 will serve almost 1200 rps on my system).
1310 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
1311 supports two config directives, mmapfile (same behavious as
1312 mod_mmap_static) and cachefile. Use the cachefile directive
1313 to cache open file handles. This directive only works on systems
1314 that have implemented the ap_sendfile API. cachefile works today
1315 on Windows NT, but has not been tested on any flavors of Unix.
1318 *) Cleanup the configuration. With the last few changes the
1319 configuration process automatically:
1320 inherits information about how to build from APR. Allowing
1321 APR to inform Apache that it should or should not use -ldl
1323 Detects which mod_cgi should be used mod_cgi or mod_cgid,
1324 based on the threading model
1326 Apache calls APR's configure process before finishing it's
1327 configuration processing, allowing for more information flow
1332 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
1333 with non-zero argument makes the socket non-blocking. BeOS and
1334 OS/2 already worked this way. [Jeff Trawick]
1336 *) ap_close() now calls ap_flush() for buffered files, so write
1337 operations work a whole lot better on buffered files.
1340 *) Fix error messages issued from MPMs which explain where to change
1341 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
1344 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
1345 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
1346 now the way that the blocking state of a pipe is manipulated.
1347 ap_block_pipe() is gone. [Jeff Trawick]
1349 *) Correct the problem where the only local host name that the IP stack
1350 can discover are 'undotted' private names. If no fully qualified
1351 domain name can be identified, the default ServerName will be set to
1352 the machine's IP address string. A warning is always provided if the
1353 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
1355 *) Repair problems with config file processing which caused segfault
1356 at init when virtual hosts were defined and which caused ServerName to
1357 be ignored when there was no valid DNS setup. [Jeff Trawick]
1359 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
1361 *) Add ap_sendfile implementation for AIX
1362 [Victor J. Orlikowski]
1364 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
1365 apr_network_io.h, and apr_thread_proc.h.
1366 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
1368 *) Bring the allocation and pool debugging code back into a working
1369 state. This will need to be tested as so far it's only been used on
1372 *) Change configuration command setup to be properly typesafe when in
1373 maintainer mode. Note that this requires a compiler that can initialise
1374 unions. [Ben Laurie]
1376 *) Turn on buffering for config file reads. Part of this was to
1377 repair buffered I/O support in Unix and implement buffered
1378 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
1380 *) Win32: Fix problem where UTC offset was not being set correctly
1381 in the access log. Problem reported on news group by Jerry Baker.
1384 *) Fix segfault when reporting this type of syntax error:
1385 "</container> without matching <container> section", where
1386 container is VirtualHost or Directory or whatever.
1389 *) Prevent the source code for CGIs from being revealed when using
1390 mod_vhost_alias and the CGI directory is under the document root
1391 and a user makes a request like http://www.example.com//cgi-bin/cgi
1392 as reported in <news:960999105.344321@ernani.logica.co.uk>
1395 *) Add support for the new Beos NetwOrking Environment (BONE)
1398 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
1399 final input char is incomplete; ap_bwrite_xlate() now handles
1400 incomplete final input chars. [Jeff Trawick]
1402 *) Yet another update to saferead/halfduplex stuff -- need to ensure
1403 that a bhalfduplex call occurs before logging or else DNS and
1404 such can delay the last packet of the response. [Dean Gaudet]
1406 *) Some syscall reduction in APR on unix -- don't seek when setting
1407 up an mmap; and don't fcntl() more than once per socket.
1410 *) When mod_cgid is started as root, the cgi daemon now switches
1411 to the configured User/Group (like other httpd processes)
1412 instead of continuing as root. [Jeff Trawick]
1414 *) The prefork MPM now uses an APR lock for the accept() mutex.
1415 It has not been getting a lock at all recently. httpd -V now
1416 displays APR's selection of the lock mechanism instead of the
1417 symbols previously respected by prefork. [Jeff Trawick]
1419 *) Change the mmap() feature test to check only for existence.
1420 The previous check required features not used by Apache.
1423 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
1424 sometimes mangled. The len parm to accept() was not
1425 initialized, leading sometimes to an endless loop of failed
1426 accept() calls on OS/390 and anywhere else that failed the call
1427 if the len was negative. Use <sys/un.h> for struct sockaddr_un
1428 instead of declaring it ourselves to fix a compilation problem
1429 on Solaris. [Jeff Trawick]
1431 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
1433 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
1435 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
1437 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
1438 initialization if ALLOC_DEBUG is defined; no known symptom
1439 otherwise. [Jeff Trawick]
1441 *) Fix typo in configure script when checking for mod_so. bash
1442 doesn't seem to have a problem but /bin/sh on Solaris does.
1443 Symptom: "./configure: test: unknown operator =="
1446 *) Rebind the Win32 NT and 9x services control into the MPM.
1447 All console, WinNT SCM and Win9x pseudo-service control code is
1448 now wrapped within the WinNT MPM.
1451 *) Make a copy of getenv("PATH") before storing for later use. Some
1452 getenv() implementations use the same storage for successive calls.
1453 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
1455 *) Server Tokens work in 2.0 again. This also propogates the change
1456 to allow just the product name in the server string using
1460 Changes with Apache 2.0a4
1462 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
1463 won't need to call it. [Greg Ames, Jeff Trawick]
1465 *) Move pre_config hook call to between configuration read and config
1466 tree walk. This allows all modules to implement pre_config hooks
1467 and know that they will be called at an appropriate time.
1470 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
1473 *) Add pre-config hooks back to all modules.
1476 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
1477 ContentDigest enabled and we can't/don't mmap the file.
1480 *) We now report the correct line number for syntax errors in config
1481 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
1483 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
1484 related bugs, and changed shmem/locking to use apr API. Shared-mem
1485 is currently disabled, however, because of problems with graceful
1486 restarts. [Ronald Tschalär]
1488 *) Fix corruption of IFS variable in --with-module= handling.
1489 Depending on the user's shell or customization thereof, there
1490 would be errors generating ap_config_auto.h later in the configure
1491 procedure. [Jeff Trawick]
1493 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
1494 isn't used (as in 1.3), except that on Unix it is now logged via
1495 ap_log_rerror() instead of by the child having STDERR_FILENO refer
1496 to the error log. [Greg Ames, Jeff Trawick]
1498 *) Add '-D' argument processing for run time configuration defines.
1501 *) Organize http_main.c as independent code, such that no code or
1502 global data is exported from it. WIN32 will dynamically link it
1503 to the server core, so this will prevent mutual dependency.
1506 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
1507 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
1510 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
1511 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
1513 *) Add mod_charset_lite for configuring character set translation.
1516 *) Add '-n' option to htpasswd to make it print its user:pw record
1517 on stdout rather than having to frob a text file. [Ken Coar]
1519 *) Fix saferead. Basically, we flush the output buffer if a read on the
1523 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
1524 a conversion is single-byte only. [Jeff Trawick]
1526 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
1527 the BeOS 5.0 documentation says that shutdown doesn't work yet.
1530 *) Fix some minor errors where pid was being manipulated as an int
1531 instead of the portable pid_t. [Roy Fielding]
1533 *) Fix some error log prints that were printing the pointer to a
1534 structure rather than the pid within the structure.
1535 [Jeff Trawick, Roy Fielding]
1537 *) ab: Fix a command-line processing bug; track bad headers in
1538 err_response; support reading headers up to 2K.
1539 [Ask Bjoern Hansen <ask@valueclick.com>]
1541 *) Fix ap_resolve_env() so that it handles new function added in a prior
1542 alpha (see "Added the capability to do ${ENVVAR} constructs in the
1543 config file.") as well as the constructs used by mod_rewrite.
1544 [Paul Reder <rederpj@raleigh.ibm.com>]
1546 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
1548 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
1549 APR to perform translation, instead of accessing the hard-coded tables
1550 in 1.3's ebcdic.c. [Jeff Trawick]
1552 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
1555 *) Add the ability to hook into the config file reading phase. Basically
1556 if a directive is specified EXEC_ON_READ, then when that directive is
1557 read from the config file, the assocaited function is executed. This
1558 should only be used for those directives that must muck with HOW the
1559 server INTERPRETS the config. This should not be used for directives
1560 that re-order or replace items in the config tree. Those changes should
1561 be made in the pre-config step.
1564 *) Add mod_example to the build system.
1567 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
1568 byte character sets. [Jeff Trawick]
1570 *) Pick up various EBCDIC fixes from 1.3 (from Martin
1571 Kraemer and Oliver Reh originally according to the change log).
1574 *) Fix a couple of problems in RFC1413 support (controlled by the
1575 IdentityCheck directive). Apache did not build the request string
1576 properly and more importantly Apache would loop forever if the
1577 would-be ident server dropped the connection before sending a
1578 properly terminated response. [Jeff Trawick]
1580 *) apxs works in 2.0.
1583 *) Reliable piped logs work in 2.0.
1586 *) Introduce a hash table implementation into APR to be used for
1587 replacing tables and other random data structures in Apache.
1590 *) Add some more error reporting to htpasswd in the case of problems
1591 generating or accessing the temporary file. Also, pass in a
1592 buffer if the implementation knows how to use it (i.e., if L_tmpnam
1593 is defined). [Ken Coar]
1595 *) Configure creates config.nice now containing your configure
1596 options. Syntax: ./config.nice [--more-options]
1599 *) Fix various return code problems in APR on Win32. For most of
1600 these, APR was returning APR_EEXIST instead of GetLastError()/
1601 WSAGetLastError(). [Jeff Trawick]
1603 *) Make piped logs work again in version 2.0
1606 *) Add VPATH support to UNIX build system of Apache and APR.
1609 *) Fix ap_tokenize_to_argv to respect the const arguments that are
1613 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
1614 Patch submitted to author.
1617 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
1618 /sbin in PATH on FreeBSD (all submitted to rse previously)
1621 *) Fix building Pthread-based MPMs on OpenBSD
1622 [Sascha Schumann] PR#26
1624 *) Fix ap_readdir() problem on systems where d_name[] field in
1625 struct dirent is declared with only one byte. (This problem only
1626 affected multithreaded builds.) This caused a segfault during
1627 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
1628 least). [Jeff Trawick]
1630 *) Fix some make-portability problems on at least Tru64, Irix
1632 [Sascha Schumann] PR#18, PR#39
1634 *) Add ap_sigwait() to support old-style sigwait() on systems
1635 like OS/390 and UnixWare.
1638 *) Add POSIX-thread flags for more platforms.
1641 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
1642 (on Unix, at least) to handle resolver errors. Fix a bug in
1643 the definition of APR_ENOMEM so that ap_strerror() can spit
1644 out the correct error message for it.
1647 Changes with Apache 2.0a3
1649 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
1652 *) API: *HOOK* macros now have an AP_ prefix
1655 *) Win32: Eliminate redundant calls to initialize winsock.
1656 [Tim Costello <timcostello@ozemail.com.au>]
1658 *) Fix bugs initializing ungetchar for pipes.
1659 [Chia-liang Kao <clkao@CirX.ORG>]
1661 *) The ab program in the src/support directory is now portable using
1665 *) Support directory is being compiled when the server is built
1668 *) The configure option --with-program-name has been added to allow
1669 developers to rename the executable at configure time. This also
1670 changes the name of the config files to match the executable's name.
1673 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
1674 containing version numbers. [Martin Pool]
1676 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
1677 Unix; access_log and error_log now created with these perms; non-
1678 Unix is unaffected [Jeff Trawick]
1680 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
1681 Replaced more magic numbers with MD5_DIGESTSIZE.
1682 [William Rowe, Roy Fielding]
1684 *) Win32: Get mod_auth_digest compiling and added to the Windows
1685 build environment. Not tested and I'd be suprised if it
1686 actually works. [Bill Stoddard]
1688 *) Revamp the Win32 make environment. Makefiles have been removed and
1689 Apache.dsw created to bring together all the pieces. Create new file
1690 os/win32/BaseAddr.ref to define module base addresses (to prevent
1691 dll relocation at start-up).
1692 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
1694 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
1695 of the \015, \012, and \015\012 constants with macros.
1696 [Greg Ames <gregames@us.ibm.com>]
1698 *) Add ap_xlate_open() et al for translation of text between different
1699 character sets. The initial implementation requires iconv().
1702 *) More FAQs and answers from comp.infosystems.www.servers.unix.
1703 [Joshua Slive <slive@finance.commerce.ubc.ca>]
1705 *) CGI output is being timed out now.
1708 *) Fix the problem with dieing quietly. dupfile now takes a pool which
1709 is used by the new apr file. There is no reason to create a new file
1710 with the same lifetime as the original file.
1713 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
1714 module base addresses. This will help shooting seg faults
1715 in the field. [William Rowe <wrowe@lnd.com>]
1717 *) Update Apache on Windows documentation. Add new document
1718 describing how to compile Apache on Windows.
1719 [William Rowe <wrowe@lnd.com>]
1721 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
1722 microseconds instead of seconds. Some storage leaks and other
1723 minor bugs in related code were fixed. [Jeff Trawick]
1725 *) Win32: First cut at getting mod_isapi working under 2.0
1726 [William Rowe <wrowe@lnd.com>]
1728 *) First stab at getting mod_auth_digest working under 2.0
1729 quick change summary:
1730 - moved the random byte generation (ap_generate_random_bytes) into APR
1731 - now uses ap_time_t
1732 - compiles and runs on linux
1734 [Brian Martin <bmartin@penguincomputing.com>]
1736 *) Win32: Move the space stripping of physical service names
1737 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
1738 unresolved symbol. Add dependency checking to the
1739 CreateService call to ensure TCPIP and AFP (winsock) is started
1741 [William Rowe <wrowe@lnd.com>]
1743 *) Win32: Add code to perform latebinding on functions that may
1744 not exist on all levels of Windows where Apache runs. This
1745 is needed to allow Apache to start-up on Win95/98. All calls
1746 to non portable functions should be protected with
1747 ap_oslevel checks to prevent runtime segfaults.
1748 [William Rowe <wrowe@lnd.com>]
1750 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
1752 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
1754 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
1755 This addresses PR 1623. Still need to address timing out runaway
1756 CGI scripts. [Bill Stoddard]
1758 *) Win32: Make ap_stat Windows 95/98 friendly
1759 [William Rowe <wrowe@lnd.com>]
1761 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
1762 always fail. Need to initialise the dwOSVersionInfoSize member of the
1763 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
1766 The patch also enhances ap_get_oslevel (and the associated enum) to
1767 handle selected service packs for NT4, and adds recognition for
1768 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
1769 we can use ReadFileScatter and WriteFileGather in readwrite.c.
1770 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
1772 *) Get mod_rewrite building and running, and mod_status building for Win NT
1773 [Allan Edwards <ake@raleigh.ibm.com>]
1775 *) Patch to port mod_auth_db to the 2.0 api and also to support
1776 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
1777 2.7.7. It should work with version 1 as well but I haven't tested it.
1778 [Brian Martin <bmartin@penguincomputing.com>]
1780 *) Get APR DSO code working under Windows. Includes cross platform
1782 [Tim.Costello@BTFinancialgroup.com]
1784 *) Fix some of the Windows APR time functions.
1787 *) FAQ changes related to tidying up historical documents on the web site.
1788 [Joshua Slive <slive@finance.commerce.ubc.ca>]
1790 *) Move Windows DSO code into APR.
1793 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
1794 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
1795 at build time. At this point, the server will not compile on Windows because
1796 of the recent DSO commits. Fixing those next.
1797 [Bill Rowe & Bill Stoddard]
1799 *) Added error checking for file I/O APR routines.
1800 [Jon Travis <jtravis@covalent.net>]
1802 *) APR: Don't use the values of resolver error codes for the
1803 corresponding APR error codes. On Unix and Win32, return the
1804 proper APR error code after a resolver error. [Jeff Trawick]
1806 Changes with Apache 2.0a2
1808 *) Renamed the executable back to httpd on all platforms other
1812 *) Allow BeOS to survive restarts, log properly and a few
1813 small things it had problems with due to the way it setup
1814 users and groups. [David Reid]
1816 *) Get mod_rewrite working with APR locks
1817 [Paul Reder <rederpj@raleigh.ibm.com>]
1819 *) Actually remove the sempahore when the lock cleanup routine
1820 is called on BeOS. [David Reid]
1822 *) Clear hook registrations between reads of the config file.
1823 When DSOs are unloaded and re-loaded the old hook pointers may
1824 no longer be valid. This fix eliminates potential segfaults.
1825 [Allan Edwards <ake@raleigh.ibm.com>]
1827 *) Fix a problem with Sigfunc not being defined or bypassed
1828 if sigaction() wasn't found. [Jim Jagielski]
1830 *) Fix the locking mechanism on BSD variants. They now use fcntl
1831 locks. This allows the server to start and serve pages.
1834 *) First cut at getting the Win32 installer to work
1835 [William Rowe <wrowe@lnd.com>]
1837 *) Get htpasswd compiling under Windows
1838 [William Rowe <wrowe@lnd.com>]
1840 *) Change the log message for a bind() failure to show the
1841 interface and port number. [Jeff Trawick]
1843 *) Import the documentation from 1.3.12 and bring parts of it
1844 up-to-date with respect to the changes that have occurred
1848 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
1849 now logged correctly on BeOS.
1852 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
1853 Makefile.win includes the same user interface as the old
1855 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
1857 *) Win32 exec now uses COMSPEC environment string for command
1858 shell path resolution.
1859 [William Rowe <wrowe@lnd.com>] PR#3715
1861 *) Win32: ap_connect() was not returning correct error condition
1863 [Allen Prescott <allen@clanprescott.com>]
1865 *) Win32: ap_open() was broken on Win9x because an NT-specific
1866 flag was passed to CreateFile. ap_puts() added an unnecessary
1868 [Jeff Trawick <trawick@us.ibm.com>]
1870 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
1871 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
1872 confusing ee/et name and made all extensions language/dialect
1873 rather than country reflecting. Changed example files to
1874 explicit reflect the ISO charset and added a few common
1875 ones to the example config [dirkx]
1877 *) Extend external module capability. To use this, you call
1878 configure with --with-module=path/to/mod1,path/to/mod2,etc.
1881 *) Backported the various "default charset" fixes from 1.3.12,
1882 including the AddDefaultCharset directive. [Jim Jagielski]
1884 *) Added the capability to do ${ENVVAR} constructs in the
1885 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
1886 it does this on a line by line basis; i.e. if the envvar
1887 expands to something with spaces you have to protect it
1888 by adding quotes around it (Unless of course you expect it
1889 to contains more than one argument. Alternatively you
1890 can compile it on a per token basis; which is what people
1891 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
1892 hampers fancier hacks.
1893 [Dirk-Willem van Gulik]
1895 *) Changed the 'ErrorDocument' syntax in that it NO longer
1896 supports the asymetric
1898 ErrorDocument 301 "Some message
1900 Note the opening " quote, without a closing quote. It now
1901 has either the following syntaxes
1903 ErrorDocument XXX /local/uri
1904 ErrorDocument XXX http://valid/url
1905 ErrorDocument XXX "Some Message"
1907 The recognition heuristic is: if it has a space it
1908 is a message. If it has no spaces and starts with a /
1909 or is a valid URL then treat it that way. Otherwise it
1910 is assumed to be a message.
1912 This breaks backward compatibility but makes live a hell
1913 of a lot easier for GUI's and config file parsers.
1914 [Dirk-Willem van Gulik]
1916 *) Changed 'CacheNegotiatedDocs' from its present/not-present
1917 syntax into a 'on' or 'off' syntax. As it currently is the
1918 only non nesting token which uses NO_ARGS and thus is an
1919 absolute pain for any config interface automation. This
1920 breaks backward compatibility. [Dirk-Willem van Gulik]
1922 *) Add ability to add external modules to the build process. This is
1923 done with --with-module=/path/to/module. Modules can only be added
1924 as static modules at this point.
1927 Changes with Apache 2.0a1
1929 *) Fix FreeBSD 3.3 core dump.
1930 Basically, ap_initialize() needs to get called before
1931 create_process(), since create_process() passes op_on structure
1932 to semop() to get a lock, but op_on isn't initialized until
1933 ap_initialize() calls setup_lock(). Here is a slight
1934 rearrangement to main() which calls ap_initialize() earlier...
1935 [Jeff Trawick <trawick@us.ibm.com>]
1937 *) Enable Apache to use sendfile/TransmitFile API
1938 [Bill Stoddard, David Reid, Paul Reder]
1940 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
1944 *) Make file I/O and network I/O writev/sendv APIs consistent.
1945 Eliminate use of ap_iovec_t and use Posix struct iovec.
1946 Use seperate variable on ap_writev to set the number of iovecs
1947 passed in and number of bytes written.
1950 *) Adapt file iol to use APR functions. Replaced ap_open_file()
1951 with ap_create_file_iol(). ap_create_file_iol() requires that
1952 the file be opened prior to the call using ap_open().
1955 *) Port mod_include and mod_cgi to 2.0
1956 [Paul Reder, Bill Stoddard]
1958 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
1959 bytes_read/bytes_written is always valid (never -1). Plus
1960 some fixes to buff.c to correct problems introduced by the
1961 errno => ap_status_t changes a while back. Plus a fix to
1962 chunked encoding introduced right at the beginning of 2.0.
1965 *) Revamped UNIX build system to use autoconf and libtool.
1966 [Manoj Kasichainula, Sascha Schumann]
1968 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
1970 *) More rigorous checking of Host: headers to fix security problems
1971 with mass name-based virtual hosting (whether using mod_rewrite
1972 or mod_vhost_alias).
1973 [Ben Hyde, Tony Finch]
1975 *) Add back support for UseCanonicalName in <Directory> containers.
1976 [Manoj Kasichainula]
1978 *) Added APLOG_STARTUP log type. This allows us to write an error
1979 message without any of the date and time information. As a part
1980 of this change, I also removed all of the calls to fprintf(stderr
1981 and replaced them with calls to ap_log_error using APLOG_STARTUP
1982 writing to stderr is no longer portable, because we don't direct
1983 stderr to the error log on all platforms.
1986 *) Convert error logging functions to take errno as an argument.
1987 This makes our error logs more portable, because some Windows API's
1988 don't set errno. This change allows us to still output a valid
1989 message on all of our platforms.
1992 *) mod_mime_magic runs in 2.0-dev now.
1993 [Paul Reder <rederpj@raleigh.ibm.com>]
1995 *) sendfile has been added to APR.
1996 [John Zedlewski <zedlwski@Princeton.EDU>]
1998 *) buff.c has been converted to no longer use errno.
1999 [Manoj Kasichainula]
2001 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
2002 interface adaption to APR functions did it. [Martin Kraemer]
2004 *) Support DSOs properly on 32-bit HP-UX 11.0
2005 [Dilip Khandekar <dilip@cup.hp.com>]
2007 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
2008 [Ralf S. Engelschall]
2010 *) Cleaned APR build environment integration and bootstrap APR
2011 automatically for developers from src/Configure.
2012 [Ralf S. Engelschall]
2014 *) Fixed building of src/support/htpasswd.c
2015 [Ralf S. Engelschall]
2017 *) When generating the Location: header, mod_speling forgot
2018 to escape the spelling-fixed uri. (Forw-Port from 1.3)
2021 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
2023 *) Change all pools to APR contexts. This is the first step to
2024 incorporating APR into Apache. [Ryan Bloom]
2026 *) Move "handler not found" warning message to below the check
2027 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
2028 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
2030 *) Support line-continuation feature in config.option file and
2031 allow the loading of multiple option sections at once via
2032 ``--with-option=<section1>,<section2>,...''
2033 [Ralf S. Engelschall]
2035 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
2037 Changes with Apache MPM
2039 *) Use asynchronous AcceptEx() and a completion port to accept and
2040 dispatch connections to threads in Windows NT/2000.
2043 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
2046 *) Implement the APACI --with-option facility
2047 (per default used the config.option file).
2048 [Ralf S. Engelschall]
2050 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
2052 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
2053 Replace pre_connection module call with a register_hook call and
2054 implement pre_connection as a hook. The intent is that these hooks will
2055 be extended to allow Apache to be multi-protocol, and also to allow the
2056 calling order to be specified on a per-hook/per-module basis.
2059 *) Implement mpm_* methods as "modules". Each method gets its own
2060 subdir in src/modules (eg: src/modules/prefork). Selection
2061 of method uses Rule MPM_METHOD. [Jim Jagielski]
2063 *) Port the hybrid server from the apache-apr repository as
2064 mpm_mpmt_pthread. [Manoj Kasichainula]
2066 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
2067 amongst the unix MPMs.
2069 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
2070 signal handling for the new world order. [Dean Gaudet]
2072 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
2073 of alloc.c for now. [Dean Gaudet]
2075 *) Handle partial large writes correctly. [Ben Laurie]
2077 *) Eliminate conn_rec's pointer to server. All it knows is the base server
2078 based on IP/port. [Ben Laurie]
2080 *) Port a bunch of modules to the new module structure.
2081 ["Michael H. Voase" <mvoase@midcoast.com.au>]
2083 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
2085 *) Basic restructuring to introduce the MPM concept; includes various
2086 changes to the module API... better described by
2087 docs/initial_blurb.txt. [Dean Gaudet]
2089 Changes with Apache pthreads
2091 *) New buff option added: BO_TIMEOUT. It describes the timeout for
2092 buff operations (generally over a network).
2093 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
2095 *) Created http_accept abstraction. Added 4 new functions (not exported):
2096 init_accept(), begin_accepting_requests(), get_request(),
2097 stop_accepting_requests() [Bill Stoddard]
2099 *) Fix to ap_rprintf call that allows mod_info to work properly.
2100 [James Morris <jmorris@intercode.com.au>]
2102 *) user and ap_auth_type fields were moved from connection_rec to
2103 request_rec. [Ryan Bloom]
2105 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
2106 needed in a threaded server.
2108 *) Initial pthread implementation from from Dean's apache-nspr code.
2109 [Bill Stoddard, Ryan Bloom]
2112 Changes with Apache 1.3.9
2114 *) Remove bogus error message when a redirect doesn't set Location.
2115 Instead, use an empty string to avoid coredump if the error message
2116 was supposed to include a location. [Roy Fielding]
2118 *) Don't allow configure to include mod_auth_digest unless it is
2119 explicitly requested, even if the user asked for all modules.
2122 *) Translate module names to dll names for OS/2 so that they are no more
2123 than 8 characters long and have an extension of "dll" instead of "so".
2126 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
2127 Fix test-compile check to check for randbyte instead of trand32.
2128 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
2129 and tweak to make Amaya happier. [Ronald Tschalär]
2131 *) Ensure that the installed expat include files are world readable,
2132 just like the other header files. [Martin Kraemer]
2134 *) Fixed generated AddModule adjustments in APACI's `configure' script
2135 in order to allow (new) modules like mod_vhost_alias to be handled
2136 correctly (which was touched by the adjustments for mod_alias).
2137 [Ralf S. Engelschall]
2139 *) For binary builds, add -R flag to apachectl to work around the lack of
2140 an absolute path to the ./libexec directory where the libhttp.ep file
2141 is needed for SHARED_CORE architectures. [Randy Terbush]
2143 *) WIN32: Create the CGI script process as DETACHED. This may solve the
2144 problem observed by some Win95/98 users where they get CGI script
2145 output sent to the console. [Bill Stoddard]
2147 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
2148 routines are now called ap_base64* and are 'plain' (i.e., no
2149 pool access or anything clever). Inside util.c the routines acting
2150 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
2151 The oddly named ap_uuencode(), ap_uudecode() are kept around for
2152 now but deprecated. [dirkx]
2154 *) Clean up the base64 and SHA1 additions and make sure they are
2155 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
2156 files. [Roy Fielding]
2158 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
2159 checking. Allow compiling on VS 6.0. [Randy Terbush]
2161 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
2163 *) Use TestCompile to search for the truerand library (rather than blindly
2164 assuming its existence). If it is not found, complain (but do not
2165 exit - yet). [Martin Kraemer]
2167 *) We forgot to add the new exported function names to
2168 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
2170 *) Add description of -T command-line option to usage().
2171 [Ralf S. Engelschall]
2173 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
2174 searched only AFTER libap has been searched, because libap needs
2175 some symbols from libos. [Martin Kraemer]
2177 *) Fix conflict with original mod_digest related to the symbol of the
2178 module dispatch list (which has to be unique for DSO and follow the
2179 usual conventions for the installation procedure).
2180 [Ralf S. Engelschall]
2182 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
2183 for other platforms as well. [Martin Kraemer]
2185 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
2186 types by AP_LONG and replace reference to renamed variable 'ubuf'
2187 by 'buffer'. [Martin Kraemer]
2189 Changes with Apache 1.3.8 [not released]
2191 *) Flush the output buffer immediately after sending an error or redirect
2192 response, since the result may be needed by the client to abort a
2193 long data transfer or restart a series of pipelined requests.
2194 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
2196 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
2197 [Ian Turner <iant@sequent.com>] PR#4735
2199 *) Local struct mmap in http_core.c conflicted with system structure
2200 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
2202 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
2203 [Ronald Tschalär <ronald@innovation.ch>]
2205 *) Fix a memory leak where the module counts were getting messed
2206 up across restarts. [David Harris <dharris@drh.net>]
2208 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
2209 properly in mod_access.
2210 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
2212 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
2213 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
2215 *) PORT: Support for compaq/tandem/com.
2216 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
2218 *) Added SHA1 password encryption support to easy migration from
2219 Netscape servers. See support/SHA1 for more information.
2220 Caused the separation of ap_md5.c into md5, sha1 and a general
2221 ap_checkpass.c with just a validate_passwd routine. Added a
2222 couple of flags to support/htpasswd. Some reuse of the to64()
2223 function; hence renamed to ap_to64().
2224 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
2226 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
2227 with ASCII/EBCDIC conversions in "ident" query.
2228 [David McCreedy <McCreedy@us.ibm.com>]
2230 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
2231 Change "Power Macintosh" to Power* so if uname prints "Power Book"
2232 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
2234 *) Fix SIGSEGV on some systems because the Vary fix below included
2235 a call to table_do with a variable argument list that was not
2236 NULL terminated. Replaced with better implementation. [Roy Fielding]
2238 Changes with Apache 1.3.7 [not released]
2240 *) The "Vary" response header field is now sanitised right before
2241 the header is sent back to the client. Multiple "Vary" fields
2242 are combined, and duplicate tokens (e.g., "Vary: host, host" or
2243 "Vary: host, negotiate, host, accept-language") are reduced to
2244 single instances. This is a better solution than the force-no-vary
2245 one (which is still valid for clients that can't cope with Vary
2246 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
2248 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
2250 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
2251 least on Linux and FreeBSD for now.
2254 *) Win32: More apache -k restart work. Restarts are now honored
2255 immediately and connections in the listen queue are -not- lost.
2256 This is made possible by the use of the WSADuplicateSocket()
2257 call. The listeners are opened in the parent, duplicated, then
2258 the duplicates are passed to the child. The original listen sockets
2259 are not closed by the parent across a restart, thus the listen queue
2261 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2263 *) Fix handling of case when a client has sent "Expect: 100-continue"
2264 and we are going to respond with an error, but get stuck waiting to
2265 discard the body in the pointless hope of preserving the connection.
2266 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
2268 *) Fix 'configure' to work correctly with SysV-based versions of
2269 'tr' (consistent with Configure's use as well). [Jim Jagielski]
2271 *) apxs: Add "-S var=val" option which allows for override of CFG_*
2272 built-in values. Add "-e" option which works like -i but doesn't
2273 install the DSO; useful for editing httpd.conf with apxs. Fix
2274 editing code so that multiple invocations of apxs -a will not
2275 create duplicate LoadModule/AddModule entries; apxs can now be
2276 used to re- enable/disable a module. [Wilfredo Sanchez]
2278 *) Win32: Update the server to use Winsock 2. Specifically, link with
2279 ws2_32.lib rather than wsock32.lib. This gives us access to
2280 WSADuplcateSocket() in addition to some other enhanced comm APIs.
2281 Win 95 users may need to update their TCP/IP stack to pick up
2282 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
2283 [Bill Stoddard stoddard@raleigh.ibm.com]
2285 *) Win32: Redirect CGI script stderr (script debug info) into the
2286 error.log when CGI scripts fail. This makes Apache on Win32
2287 behave more like Unix.
2288 [Bill Stoddard stoddard@raleigh.ibm.com]
2290 *) Fixed `httpd' usage display: -D was missing.
2291 [Ralf S. Engelschall] PR#4614
2293 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
2294 [Ralf S. Engelschall] PR#4561, PR#4562
2296 *) OS/2: Fix problem with accept lock semaphores where server would die with
2297 "OS2SEM: Error 105 getting accept lock. Exiting!"
2298 [Brian Havard] PR#4505
2300 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
2301 [Randy Terbush <randy@covalent.net>]
2303 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
2304 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
2306 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
2307 command potentially _is_ GCC. [Ralf S. Engelschall]
2309 *) Fix apxs build issues on AIX
2310 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
2312 *) DocumentRoot Checking: Under previous versions, when Apache
2313 first started up, it used to do a stat of each DocumentRoot to
2314 see if it existed and was a directory. If not, then an error
2315 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
2316 does not exist, you will get error messages in error_log. If
2317 the '-t' command line option is used (to check the configuration)
2318 the check of DocumentRoot IS performed. An additional command
2319 line option, '-T', has been added if you want to avoid the
2320 DocumentRoot check even when checking the configuration.
2323 *) Win32: The query switch "apache -S" didn't exit after showing the
2324 vhost settings. That was inconsistent with the other query functions.
2325 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
2327 *) Win32: Changed behaviour of apache -k restart.
2328 Previously, the server would drain all connections in the stack's
2329 listen queue before honoring the restart. On a busy server, this
2330 could take hours. Now, a restart is honored almost immediately.
2331 All connections in Apache's queues are handled but connections in
2332 the stack's listen queue are discarded. Restart triggered by
2333 MaxRequestPerChild is unchanged.
2334 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2336 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
2337 the accept loop. Good for a 5% performance boost. Cleaned up
2338 parent/child process management code.
2339 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2341 *) Added ceiling on file size for memory mapped files.
2342 [John Giannandrea <jg@meer.net>] PR#4122
2344 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
2345 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
2346 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
2348 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
2349 use this at least for Expat. [Ralf S. Engelschall]
2351 *) Allow .module files to specify libraries with Lib:.
2354 *) Allow SetEnvIf[NoCase] to test environment variables as well
2355 as header fields and request attributes. [Ken Coar]
2357 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
2358 content-types are "text/html;parameters". PR#4524 [Ken Coar]
2360 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
2361 never accepted into any standard, and it opens up certain DoS
2362 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
2364 *) TestCompile updated. We can now run programs and output the
2365 results during the Configure process. [ Jim Jagielski]
2367 *) The source is now quad (long long) aware as needed. Specifically,
2368 the Configure process determines the correct size of off_t and
2369 *void. When the OS/platform/compiler supports quads, ap_snprintf()
2370 provides for the 'q' format qualifier (if quads are not available,
2371 'q' is silently "demoted" to long). [Jim Jagielski]
2373 *) When the username or password fed to htpasswd is too long, include the
2374 size limit in the error message. Also report illegal characters
2375 (currently only ':') in the username. Add the size restrictions
2376 to the man page. [Ken Coar]
2378 *) Fixed the configure --without-support option so it doesn't result in
2379 an infinite loop. [Marc Slemko]
2381 *) Piped error logs could cause a segfault if an error occured
2382 during configuration after a restart.
2383 [Aidan Cully <aidan@panix.com>] PR#4456
2385 *) If a "Location" field was stored in r->err_headers_out rather
2386 than r->headers_out, redirect processing wouldn't find it and
2387 the server would core dump on ap_escape_html(NULL). Check both
2388 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
2389 if Location isn't set. [Doug MacEachern, Ken Coar]
2391 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
2392 of the Expat 1.0.2 distribution. [Greg Stein]
2394 *) Replace regexec() calls with calls to a new API stub function
2395 ap_regexec(). This solves problems with DSO modules which use the regex
2396 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
2398 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
2399 environment variables can be set according to the protocol version
2400 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]

2417 *) Support for server-parsed and multiview-determined ReadmeName and
2418 HeaderName files in mod_autoindex. Removed the restriction on
2419 "/"s in ReadmeName and HeaderName directives since the *sub_req*
2420 routines will deal with the access issues. (It's now possible to
2421 have {site|group|project|customer|...} wide readmes and headers.)

2436 by default when building with APACI; allow for platform-specific
2437 variable defaults in configure. [Wilfredo Sanchez]
2439 *) Do setgid() before initgroups() in http_main; some platforms
2440 zap the grouplist when setgid() is called. This was fixed in
2441 suexec earlier, but the main httpd code missed the change.

2457 being newer than Configuration so that it is less likely to fail
2458 when using APACI and shadow sources. [Wilfredo Sanchez]
2460 *) PORT: Add initial support for Mac OS (versions 10.0 and
2461 greater). Use Mac OS X Server layout for now. Clean up dyld code
2462 in unix/os.c, and don't install the dyld error handlers, which
2463 are no longer needed in Mac OS. [Wilfredo Sanchez]
2465 *) Rename Rhapsody layout to "Mac OS X Server". Change install
2466 locations to appropriate ones for user-built (as opposed to
2467 system) installs. [Wilfredo Sanchez]
2469 *) Modify mod_autoindex's handling of AddDescription so that the
2470 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
2472 *) Add functionality to the install-bindist.sh script created by
2473 binbuild.sh to use tar when copying distribution files to the
2474 serverroot. This allows upgrading an existing installation
2475 without nesting the new distribution in the old.
2477 install-bindist.sh now detects the local perl5 path to install
2478 apxs and dbmmanage with proper path to perl interpreter.
2480 Add an install-binsupport target which copies the source files
2481 for apxs and dbmmanage to bindist to allow these scripts to
2482 be properly installed relative to the destination serverroot.

2510 value of the DirectoryIndex directive is a single dot. Also likely
2511 to happen for anyother values of DirectoryIndex that will map back

2595 *) Make {Set,Unset,Pass}Env per-directory instead of per-server.
2598 *) Correct an apparent typo: on the Windows and MPE platforms, the
2599 htpasswd utility was limiting passwords to only 8 characters.
2602 *) EBCDIC platforms: David submitted patches for two bugs in the
2603 MD5 digest port for EBCDIC machines:
2604 a) the htdigest utility overwrote the old contents of the digest file
2605 b) the Content-MD5 header value (ContentDigest directive) was wrong
2606 when the returned file was not converted from EBCDIC, but was a
2607 binary (e.g., image file) in the first place.
2608 [David McCreedy <mccreedy@us.ibm.com>]
2610 *) support/htpasswd now permits the password to be specified on the
2611 command line with the '-b' switch. This is useful when passwords
2612 need to be maintained by scripts -- particularly in the Win32
2613 environment. [Ken Coar]
2615 *) Win32: Win32 multiple services patch. Added capability to install and
2616 run multiple copies of apache as individual services.
2619 apache -n apache1 -i -f c:/httpd.conf
2620 Installs apache as service 'apache1' and associates c:/httpd.conf
2623 Starts apache1 service.
2625 Stops apache1 service
2628 apache -n apache2 -i
2629 Installs apache as service 'apache2'. httpd.conf is located under

2646 mismatches were causing compilation problems with gcc -pedantic and
2647 in the TPF cross-compilation. [Ken Coar]
2649 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
2650 a roughly 5 fold speed up. [Brian Havard]
2652 *) proxy ftp: instead of using the hardwired string "text/plain" as
2653 a fallback type for files served by the ftp proxy, use the
2654 ap_default_type() function to determine the configured type.
2655 This allows for special configurations like
2656 <Directory proxy:ftp://some.host>
2657 DefaultType gargle/blurb
2659 Additionally, add the Content-Encoding: header to FTP proxy replies
2660 when the encoding is defined (by the AddEncoding directive).
2661 Because it was missing, it was almost impossible to browse compressed
2662 files using the FTP proxy (works now perfectly in Communicator).
2663 The ftp proxy now also returns the Date: and Server: header lines (if not
2664 much else... This code is "somewhat" broken) like normal requests do.
2667 *) Be more smart in APACI's configure script when determining the UID/GID
2668 for User/Group directives and use the determined UID/GID to initialize
2669 the permissions on the proxycachedir.
2670 [Dirk-Willem van Gulik, Ralf S. Engelschall]
2672 *) Changed the forking-prior-to-cleanup in the proxy module to first
2673 check wether it actually needs to collect garbage. This reduces
2674 the number of fork()s from one/request to just the odd one an hour.
2675 [Dirk-Willem van Gulik]

2704 *) M_INVALID needed a value within the scope of METHODS so that unknown
2705 methods can be access controlled. [Roy Fielding] PR#3821
2707 *) Added PassAllEnv; makes server's entire environment available
2708 to CGIs and SSIs executed within directive's scope. [Ken Coar]
2710 *) ap_uuencode() always added two trailing '='s and encoding of
2711 8 bit characters on a machine with signed char may produced
2712 incorrect results. Additionally ap_uuencode() should now
2713 work correctly on EBCDIC platforms.
2714 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
2716 *) WIN32: Binary installer now runs the configuration DLL before
2717 the reboot prompt (which is only given if MSVCRT.DLL system
2718 DLL is new or updated). This should avoid the configuration
2719 directory being empty after installation. [Paul Sutton]
2720 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988

2724 the Apache service on NT. [Paul Sutton] PR#3741
2726 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
2728 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
2729 have been reported with flock() locking (probably related to kernel
2730 version). [Dean Gaudet] PR#2723, 3531
2732 *) Using APACI, the main config file (usually httpd.conf) was
2733 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez

2743 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
2744 for 8-bit safeness. [Dean Gaudet]
2746 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
2747 because SPARCs have a small machine-specific maximum size for the Global
2748 Offset Table which is often exceeded when compiling one of the larger
2749 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
2751 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the

2772 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
2773 possible buffer overflows. [Ralf S. Engelschall]
2775 *) Remove no longer used non-API function ap_single_module_init().
2776 [Ralf S. Engelschall]
2778 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
2781 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
2782 to make platform installations easier. [Wilfredo Sanchez]
2784 *) In configure, do not append the target name to the directory path if
2785 the path already contains "apache". [Ralf S. Engelschall]
2787 *) SIGPIPE is now ignored by the server core. The request write routines
2788 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
2789 correctly check for output errors and mark the connection as aborted.
2790 Replaced many direct (unchecked) calls to ap_b* routines with the
2791 analogous ap_r* calls. [Roy Fielding]
2793 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
2794 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
2795 Furthermore map lookups for non-existent keys are now cached as well.
2796 Additionally "txt" maps are now parsed with simple string functions
2797 instead of using ap_pregcomp(). As a side effect a bug that prevented
2798 the usage of keys containing the "," character was fixed.
2799 The changes drastically improve the performance when large rewrite maps
2801 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
2803 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
2804 other than GET, and const'd the definition of method in request_rec.
2807 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
2809 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
2810 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
2812 *) Add %V to mod_log_config, this logs the hostname according to the
2813 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
2814 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
2816 *) Add support for \n and \t to mod_log_config, can be used to produce
2817 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
2819 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
2821 *) Added informative error messages for failed munmap() and fseek() calls
2822 in http_core.c. [John Bley, Roy Fielding]
2824 *) Added some informative error messages for some failed malloc()
2825 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
2827 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
2828 is removed. This allows <Directory proxy:*> directives to work and
2829 prevents invalid requests from killing the process.
2830 [Brian Havard <brianh@kheldar.apana.org.au>]
2832 *) Reorganised FAQ document.
2833 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497

2836 David N. Welton: you can now have it generate an HTML TABLE, presumably
2837 for integration into other HTML sources. David updated the ab man page
2838 as well and added some missing descriptions. Thanks!
2839 [David N. Welton <davidw@prosa.it>]
2841 *) Win32: The filename validity checker now allows filenames containing
2842 characters in the range 0x80 to 0xff (for example accented characters).
2843 [Paul Sutton] PR#3890
2845 *) Added conditional logging based upon environment variables to
2846 mod_log_config. mod_log_referer and mod_log_agent
2847 are now deprecated. [Ken Coar]
2849 *) Allow apache acting as a proxy server to relay the real
2850 reason of a failure to a client rather than the "internal
2851 server error" it does currently. The general exposure mechanism
2852 can be triggered by any module by setting the "verbose-error-to"
2853 note to "*"; this allows more than just proxy errors to be exposed.
2854 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
2856 *) Moved man pages for ab and apachectrl to section 8.
2857 [Wilfredo Sanchez, Roy Fielding]
2859 *) Added -S option to install.sh so that options can be passed to
2860 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
2862 *) Tweak modules Makefile generated by Configure so that it handles
2863 the test case of no modules being selected. [chaz@reliant.com]
2865 *) Added a <LimitExcept method ...> sectioning directive that allows
2866 the user to assign authentication control to any HTTP method that
2867 is *not* given in the argument list; i.e., the logical negation
2868 of the <Limit> directive. This is particularly useful for controlling
2869 access on methods unknown to the Apache core, but perhaps known by
2870 some module or CGI script. [Roy Fielding, Tony Finch]
2872 *) Prevent apachectl from complaining if the PIDFILE exists but
2873 does not contain a process id, as might occur if the server is
2874 being rapidly restarted. [Wilfredo Sanchez]
2876 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
2878 *) Entity tag comparisons for If-Match and If-None-Match were not being
2879 performed correctly -- weak tags might cause false positives. Also,
2880 strong comparison wasn't properly enforced in all cases.
2881 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
2883 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
2886 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
2887 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
2889 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
2890 to util.c for parsing an HTTP header field value to extract the next
2891 list item, taking into account the possible presence of nested comments,
2892 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
2893 insignificant whitespace and lowercases non-quoted tokens.
2894 [Roy Fielding] PR#2065
2896 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
2897 code different from 500. This allows the proxy to, e.g., return
2898 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
2900 *) Fix ordering of language variants for the case where the traditional
2901 negotiation algorithm is being used with multiple language variants
2902 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
2904 *) Do not round the TCN quality calculation to 5 decimal places,
2905 unlike RFC 2296, because the calculation might need 12 decimal places
2906 to get the right result. [Roy Fielding]
2908 *) Remove unused code to disable transparent negotiation when
2909 negotiating on encoding only, as we now handle encoding too
2910 (though this is nonstandard for TCN), remove charset=ISO-8859-1
2911 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
2912 some debugging statements within mod_negotiation. [Koen Holtman]
2914 *) Fixed a rare memory corruption possibility in mod_dir if the index
2915 file is negotiable and no acceptable variant can be found.
2916 [Dean Gaudet, Roy Fielding, Martin Kraemer]
2918 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
2919 searching the Win32 registry for script interpreters.
2922 *) Win32: The compiled-in default filename for the error log is now
2923 error.log, which matches the default in the distributed httpd.conf.
2926 *) Win32: Any error messages from -i or -u command line options are now
2927 displayed on the console output rather than sent to the error log.
2928 Also the "Running Apache..." message is not output unless Apache is
2929 going to serve requests. [Paul Sutton]
2931 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
2932 and use a private significator ('$apr1$') to mark passwords as
2933 being smashed with our own algorithm. Also abstract the password
2934 checking into a new ap_validate_password() routine. [Ken Coar]
2936 *) Win32: The filename validity checker now allows "COM" but refuses
2937 access to "COM1" through "COM4". This allows filenames such
2938 as "com.name" to be served. [Paul Sutton] PR#3769.
2940 *) BS2000: Adapt to the new ufork() system call interface which will
2941 make subtasking easier on the OSD/POSIX mainframe environment.

2945 ap_compat.h. [David White <david@persimmon.com>] PR#3725
2947 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
2948 use `.db' instead of `.pag' not only for FreeBSD, but also when
2949 the NDBM library looks like Berkeley-DB based.

2955 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
2957 *) SECURITY: Avoid some buffer overflow problems when escaping
2958 quoted strings. (This overflow was on the heap and we believe
2959 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
2961 *) Let src/Configure be aware of CFLAGS options starting with plus
2962 signs as it's the case for the HP/UX compiler.
2963 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
2965 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
2966 and check to see if the tar we wind up with supports '-h'.
2967 [Jim Jagielski] PR#3671
2969 *) A consistent and conservative style for all shell scripts has been
2970 implemented. Basically, all shell string tests use the traditional
2971 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
2972 to protect against bare null variable strings (ie: wrapping both
2973 sides with double quotes and prepending 'x'). 'x' was chosen
2974 because it's more universal and hopefully easier for old shell
2975 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
2978 *) The status module now prints out both the main server generation as
2979 well as the generation of each process. Also, the vhost info is
2980 printed with '?notable'. [Jim Jagielski]
2982 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
2983 and this makes its functions available to things in src/support.
2986 Changes with Apache 1.3.4
2988 *) Renamed macros status_drops_connection to ap_status_drops_connection
2989 and vestigial scan_script_header to ap_scan_script_header_err,
2990 mostly for aesthetic reasons. [Roy Fielding]
2992 *) The query switch "httpd -S" didn't exit after showing the
2993 vhost settings. That was inconsistent with the other query functions.
2996 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
2997 filename to the end of the STANDARD_MODULE_STUFF. Its
2998 presence at the beginning prevented reporting of the filename
2999 for modules compiled before 1 January 1999. [Ken Coar]
3001 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
3002 to detect and prevent access to special DOS device file names.
3003 [Paul Sutton, Ken Parzygnat]
3005 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
3006 and Makefile_win32_debug.txt (debug build) that work on Win95.
3007 Run each of the following from the src directory:
3008 nmake /f Makefile_win32.txt # compiles normal build
3009 nmake /f Makefile_win32.txt install # compiles and installs
3010 nmake /f Makefile_win32.txt clean # removes compiled junk
3011 nmake /f Makefile_win32_debug.txt # compiles debug build
3012 nmake /f Makefile_win32_debug.txt install
3013 nmake /f Makefile_win32_debug.txt clean
3016 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
3017 to build binary distributions. [Lars Eilebrecht]
3019 *) IndexOptions SuppressColumnSorting only turned off making
3020 the column headers anchors; you could still change the display
3021 order by manually adding a '?N=A' or similar query string to the
3022 URL. Now SuppressColumnSorting locks in the sort order so
3023 it can't be overridden this way. [Ken Coar]
3025 *) Added IndexOrderDefault directive to supply a default sort order
3026 for FancyIndexed directory listings. [Ken Coar] PR#1699
3028 *) Change the ap_assert macro to a variant that works on all platforms.
3029 [Richard Prinz <richard.prinz@cso.net>] PR#2575
3031 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
3032 search for an underscore on dlsym() (as it's already the case
3033 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
3035 *) Small fix for mod_env.html: The module was documented as to be _not_
3036 compiled into Apache per default, although it _IS_ compiled into
3037 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
3039 *) Instead of fixing a bug in the generation procedure for config.status (a
3040 backslash was missing) we remove the bug together with it's complete
3041 context because the special cases of the past can now no longer occur
3042 because of the recent magic for the --with-layout default.
3043 [Ralf S. Engelschall] PR#3590
3045 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
3046 making sure the src/support/ tools are _forced_ to be build last (they
3047 depend on other libraries).
3048 [Markus Theissinger <markus.theissinger@gmx.de>]
3050 *) Fix installation procedure: Now that os-inline.c is actually used (a
3051 recently fixed bug prevented this) we need to also install os-include.c
3052 in addition to os.h into the PREFIX/include/ location or building of
3053 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
3055 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
3056 allow us to distinguish between a garbled DSO (or even a file which isn't
3057 an Apache module DSO at all) and a DSO which doesn't match the current
3058 Apache API. [Ralf S. Engelschall] PR#3152
3060 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
3061 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
3062 match case insensitive (this especially avoids nasty patterns like
3063 `[tT][eE][sS][tT]'). Second two additional internal map functions
3064 `escape' and `unescape' were added which can be used to escape/unescape
3065 to/from hex-encodings in URLs parts (this is especially useful in
3066 combination with map lookups).
3067 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
3069 *) Renamed the macro escape_uri() to ap_escape_uri() which was
3070 forgotten (because it was a macro) in the symbol renaming process.
3071 [Ralf S. Engelschall]
3073 *) Fix some inconsistencies related to the scopes of directives. The only
3074 user visible change is that the directives `UseCanonicalName' and
3075 `ContentDigest' now use the (more correct) `Options' scope instead of
3076 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
3078 *) Using DSO, the Server token was being mangled. Specifically, the
3079 module's token was being added first before the Apache token. This
3080 has been fixed. [Jim Jagielski]
3082 *) Major overhaul of mod_negotiation.c, part 2.
3083 - properly handle "identity" within Accept-Encoding.
3084 - allow encoded variants in RVSA negotiation and let them appear in
3085 the Alternates field using the non-standard "encoding" tag-list.
3086 - fixed both negotiation algorithms so that an explicitly accepted
3087 encoding is preferred over no encoding if "identity" is not
3088 included within Accept-Encoding.
3089 - added ap_array_pstrcat() to alloc.c for efficient concatenation
3090 of large substring sequences.
3091 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
3094 *) Major overhaul of mod_negotiation.c, part 1.
3095 - cleanups to mod_negotiation comments and code structure
3096 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
3097 support for everything in the upcoming HTTP/1.1
3098 revision (draft-ietf-http-v11-spec-rev-06.txt).
3099 - language tag matching also handles tags with more than 2
3101 - empty Accept, Accept-Language, Accept-Charset headers are
3102 processed correctly; previously an empty header would make all
3103 values acceptable instead of unacceptable.
3104 - allowed for q values in Accept-Encoding
3105 - added support for transparent content negotiation (rfc2295 and
3106 rfc2296) (though we do not implement all features in these drafts,
3107 e.g. no feature negotiation). Removed old experimental version.
3108 - implemented 'structured entity tags' for better cache correctness
3109 (structured entity tags ensure that caches which can deal with Vary
3110 will (eventually) be updated if the set of variants on the server
3112 - this involved adding a vlist_validator element to request_rec
3113 - this involved adding the ap_make_etag() function to the global API
3114 - modified guessing of charsets used by Apache negotiation algorithm
3115 to guess 'no charset' if the variant is not a text/* type
3116 - added code to sort multiviews variants into a canonical order so that
3117 negotiation results are consistent across backup/restores and mirrors
3118 - removed possibility of a type map file resolving to another type map
3119 file as its best variant

3131 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]
3133 *) For %v log ServerName regardless of the UseCanonicalName
3134 setting (similarly for %p). [Dean Gaudet]
3136 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
3137 rather late (too late for some invocations of TestCompile).
3138 This improves the make environment available to TestCompile and
3139 the *.module scripts. [Martin Kraemer]
3141 *) The hashbang emulation code in ap_execve.c would interpret
3142 #!/hashbang/scripts correctly, but failed to fall back to a
3143 standard shell for scripts which did NOT start with #!
3144 Now SHELL_PATH is started in these cases. [Martin Kraemer]
3146 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
3149 *) Update APXS manual page: some -q option arguments were missing
3150 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
3152 *) Cleanup the command line options: `-?' was documented to show
3153 the usage list but does it with an error because `?' is not a valid
3154 command. OTOH a lot of users expect `-h' to print such a usage list and
3155 instead are annoyed for ages by our huge unreadable list of directives.
3156 So we now changed the command line options this way:
3158 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
3159 very similar to the popular linker option.
3161 Intent: while -l gives the small list of modules, -L now gives the
3162 large list of directives implemented by these modules. This is also
3163 consistent with -v (short version info) and -V (large version info).
3165 Intent: it's now the expected option ;-)
3166 The manual page was adjusted accordingly.
3167 [Ralf S. Engelschall] PR#2714
3169 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
3170 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
3172 *) Removed recently introduced bugs and disfigurements in APACI:
3173 o fixed argument line processing: using $args was broken: It was not
3174 initialized and using args="$args $apc_option" and even args="$args
3175 \"$apc_option\"" fails in the second processing round for any arguments
3176 containing whitespaces. The only correct way is to use the construct
3177 "$@" (but not possible here) or iterate _both_ times over the implicit
3178 argument line (no argument to for-loop) which is what we now use.
3179 o make --with-layout=Apache the default without creating
3180 redundancy (copying the --with-layout block in the argument parsing
3181 loop). We achieve this by using the "$@" construct together with the
3182 `set' command to prepend --with-layout=Apache to the command line in
3183 case --with-layout is not used.
3184 o fixed auto-suffix handling now that config.layout exists.
3185 Paths which are auto-suffixed are marked with a trailing plus sign in
3186 config.layout and every path now can be marked this way (not only the
3187 four paths for which we do it currently). Additionally the suffix is
3188 no longer a static one. Instead it's now `/<target>' where <target> is
3189 the argument of the --target option or per default `httpd'.
3190 o allow also tabs (and only spaces) where we match whitespaces
3191 o various fixes and cleanups related to used shell coding style
3192 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
3193 o trimmed output of --help to fit into 80 columns
3194 [Ralf S. Engelschall]
3196 *) Added two new core API functions, ap_single_module_configure() and
3197 ap_single_module_init(), which are now used by mod_so to configure a module
3198 after loading. [Ralf S. Engelschall]
3200 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
3201 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
3202 of ap_config.h to allow serialized accept for multiport listens.
3203 [Roy Fielding, Curt Sampson] PR#3120
3205 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
3206 of ap_config.h that would skip several defines if DEFAULT_GROUP
3207 was overridden. [Roy Fielding]
3209 *) PORT: The I86 version of DGUX has support for strncasecmp and
3210 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
3212 *) Fix ordering of definitions in ap_config.h so that ap_inline is
3213 defined before it might be used. [Victor Khimenko]
3215 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
3216 [Tom Serkowski <tks@bsdi.com>] PR#3453
3218 *) Make generation of src/Configuration.apaci more robust: It failed to
3219 differenciate between modules when one module name was a postfix of
3220 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
3221 just XXX (think about totally non-standard names like "apache_ssl", too).
3222 [Ralf S. Engelschall] PR#3380
3224 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
3225 since 1.3b7) and make whitespace handling more robust (it failed horrible
3226 when whitespaces were present in the arguments of -D options).
3227 [Ralf S. Engelschall] PR#3240
3229 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
3230 creates an external package shadow tree in DIR before the local build
3231 shadow tree is generated under DIR. This way one can have the extracted
3232 Apache distribution tree read-only on NFS or CDROM and still build Apache
3233 from these sources. An automatically triggered VPATH-like mechanism is
3234 provided through the TOP variable, too.
3235 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez@apple.com>]
3237 *) Fix negotiation so that a Vary response header is correctly
3238 generated when, for a particular dimension, variants only vary
3239 in having or not having a value for that dimension. [Paul Sutton]
3241 *) Fix negotiation so that we prefer an encoded variant over an
3242 unencoded variant if the user-agent explicitly says it can
3243 accept that encoding. Previously we always preferred the unencoded
3245 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
3247 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
3248 and the usage page was inconsistent with the functionality and manpage.
3249 [Ralf S. Engelschall]
3251 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
3252 They can occur multiple times and their arguments (`xxx') are passed AS
3253 IS to the compiler/linker command. [Ralf S. Engelschall]
3255 *) Fixed possible (but harmless in practice) bug in the DBM lookup
3256 procedure of mod_rewrite: very long keys were truncated.
3257 [Ralf S. Engelschall]
3259 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
3260 identifier, currently "Apache" and "GNU" are pre-defined in the file
3261 config.layout. Custom layouts are possible by using FILE:ID as the
3262 argument where the layout ID is taken from FILE.
3264 The config.layout file consists of <Layout ID>..</Layout> sections
3265 where inside those sections "path_variable: path_value" pairs can be
3266 specified. These lines are converted to path_variable='path_value'.
3268 *) Add a DefaultLanguage directive so that files missing a language
3269 extension (e.g., .fr, .de) can be labelled as being some other
3270 default language. DefaultLanguage can appear in <Directory> and
3271 <Files> containers as well as .htaccess files. [Paul Sutton]
3274 *) Fix TARGET configuration when configuring and installing using
3275 APACI configure. TARGET now defines the basename of the configuration
3276 file, startup script, manual page, etc. log_error_core() now reports
3277 the server binary name given by argv[0]. TARGET can now also be defined
3278 with --target=TARGET parameter passed to APACI configure.

3354 script failed, including the command line used to attempt to execute
3355 the interpreter and the Win32 error code returned. [Marc Slemko]
3357 *) Disable sending of error-notes on a 500 (Internal Server Error) response
3358 since it often includes file path info. Enable sending of error-notes
3359 on a 501 (Method Not Implemented). [Roy Fielding] PR#3173
3361 *) http_config.c would respond with 501 (Method Not Implemented) if a
3362 content type handler was specified but could not be found, which
3363 should have been a 500 response. Likewise, mod_proxy.c would responsd
3364 with a 501 if the URI scheme is unrecognized instead of the correct
3365 response of 403 (Forbidden). [Roy Fielding]
3367 *) SECURITY: Eliminate DoS attack when a bad URI path contains what
3368 looks like a printf format escape. [Marc Slemko, Studenten Net Twente]
3370 *) Fix in mod_autoindex: for files where the last modified time stamp was
3371 unavailable, an empty string was printed which was 2 bytes short.
3372 The size and description columns were therefore not aligned correctly.
3373 [Martin Kraemer] (no PR#)
3375 *) Update BS2000 OS code to work with recent versions. Starting with
3376 release A17, the child fork() must be replaced by a _rfork().
3377 (BS2000 only) [Martin Kraemer]
3379 *) Add the actual server_rec structure of the specific Vhost to the
3380 scoreboard file and avoid a string copy (as well as allow some
3381 further future enhancements). [Harrie Hazewinkel
3382 <harrie.hazewinkel@jrc.it>]
3384 *) Add APACI --permute-module=foo:bar option which can be used to
3385 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
3386 in the Configuration[.apaci] file. Two special and important variants are
3387 supported for the option argument: first BEGIN:foo which permutes module
3388 mod_foo with the begin of the module list, i.e. it `moves' the module to
3389 the begin of the list (gives it lowest priority). And second foo:END
3390 which permutes mod_foo with the end of the module list, i.e. it `moves'
3391 the module to the end of the list (gives it highest priority).

3394 *) Fix problem with 'apache -k shutdown' and startup event
3395 synchronisation (Win32). [Ken Parzygnat <kparz@raleigh.ibm.com>]
3398 *) The config parser wasn't correctly noticing a missing '>'
3399 on container start lines (e.g., it wouldn't spot
3400 "<Directory /" as a syntax error). [Ryan Bloom <rbbloom@us.ibm.com>]

3404 all handler associations for the specified file extensions.

3407 *) Properly handle & allow "nul" and ".*/null" in AccessConfig and
3408 ResourceConfig directives on Win32. Also add a note to the effect
3409 of 'useless User directive ignored on Win32' to the errorlog if
3410 a User directive is encountered on Win32.

3413 *) Fix multiple whitespace handling in imagemaps for mod_imap which was

3415 spaces in ap_cfg_getline().
3416 [Ivan Richwalski <ivan@seppuku.net>] PR#3249
3418 *) Fix Berkeley-DB/2.x support in mod_auth_db: The data structures were not
3419 initialized correctly and the db_open() call used an invalid mode
3420 parameter. [Ron Klatchko <ron@ckm.ucsf.edu>] PR#3171
3422 *) PORT: DSO support for UnixWare 7
3423 [Ralf S. Engelschall, Ron Record <rr@sco.com>]
3425 *) Merge the contents of the {srm,access}.conf-dist* files into the
3426 httpd.conf-dist* files. The srm and access files now contain
3427 only comments, and httpd.conf has all the combined contents in
3428 a rational order. [Ken Coar]
3430 *) PORT: DSO/ELF support for FreeBSD 3.0.
3431 [Ralf S. Engelschall, Dirk Froemberg <ibex@physik.TU-Berlin.DE>]
3433 *) Add a "default-handler" handler that calls the default_hander()
3434 function which is normally called for static content. This allows
3435 you to override a specific handler. [Marc Slemko]
3437 *) Further simplify checking for absolute paths by replacing an
3438 hard-coded syntax check with a call to a routine we already created to
3439 do this. [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2976, 3074
3441 *) Log an error if we encounter a malformed "require" directive
3442 in mod_auth if we know that we know that no other module can
3443 deal with it. [Marc Slemko]
3445 *) Remove ap_private_extern method of hiding conflicting symbols
3446 on the NEXT platform because it is not correct for all versions,
3447 and the versions for which it is correct are unknown.
3448 [Wilfredo Sanchez <wsanchez@apple.com>]
3450 *) Fix inheritance of IndexOptions NameWidth and remove unintended
3451 restriction on +NameWidth, +IconHeight, and +IconWidth. [Ken Coar]
3453 *) Fix per-directory config merging for cases in which a 500 error
3454 is encountered in an .htaccess file somewhere down the tree.
3457 *) Minor performance improvement to ap_escape_html(). [Roy Fielding]
3459 *) Fixed a segmentation violation in mod_proxy when a response is
3460 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
3462 Changes with Apache 1.3.3
3464 *) Added a complete implementation of the Expect header field as
3465 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
3466 response when we already know the final status, which is mighty
3467 useful for PUT responses that result in 302 or 401. [Roy Fielding]
3469 *) Remove extra trailing whitespace from the getline results as part
3470 of the protocol processing, which is extra nice because it works
3471 between continuation lines, is almost no cost in the normal case
3472 of no extra whitespace, and saves memory. [Roy Fielding]
3474 *) Added new HTTP status codes and default response bodies from the
3475 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
3476 HTTP Extension Framework (510) specifications. Did not add the
3477 WebDAV 424 and 425 codes because they are bogus. We don't use any
3478 of these codes yet, but they are now available to 3rd-party modules.
3481 *) Fix a possible race condition between timed-out requests and the
3482 ap_bhalfduplex select that might result in an infinite loop on
3483 platforms that do not validate the descriptor. [Roy Fielding]
3485 *) WIN32: Add "-k shutdown" and "-k restart" options to signal a
3486 running Apache server [Paul Sutton]
3488 *) Fix mod_autoindex bug where directories got a size of "0k" instead
3489 of "-". [Martin Plechsmid <plechsmi@karlin.mff.cuni.cz>, Marc Slemko]
3492 *) PORT: DRS 6000 machine. [Paul Debleecker <pdebleecker@jetair.be>]
3494 *) Add the server signature text (from the core ServerSignature directive)
3495 to the list of envariables available to scripts, SSI, and the like.
3498 *) PORT: Fix sys/resource.h handling for SCO 3.x platform.
3499 [M. Laak <maert@proinv.ee>] PR#3108
3501 *) Fallback from sysconf-based to plain HZ-based `ticks per second'
3502 calculation in mod_status for all systems which don't have POSIX
3503 sysconf() (like UTS 2.1) and not only for the NEXT platform.
3504 [Dave Dykstra <dwd@bell-labs.com>] PR#3055
3506 *) Fix `require ...' directive parsing in mod_auth, mod_auth_dbm and
3507 mod_auth_db by using ap_getword_white() (which uses ap_isspace())
3508 instead of ap_getword(..., ' ') (which parses only according to spaces
3509 but not tabs). [James Morris <jmorris@intercode.com.au>,
3510 Ralf S. Engelschall] PR#3105
3512 *) Fix the SERVER_NAME variable under sub-request situations (where

3536 working directory to fill in some blanks. [Ken Parzygnat
3537 <kparz@raleigh.ibm.com>] PR#3001

3550 *) PORT: Allow GuessOS to recognize Unixware 7.0.1 [Steve Cameron
3551 <steve.cameron@compaq.com>]
3553 *) Reconstructed the loop through multiple htaccess file names so
3554 that missing files are not confused with unreadable files.
3557 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
3558 errno on an error, which leads to one error being mistaken for
3559 another when reading non-existent .htaccess files.
3562 *) OS/2: The new header tests get things right, need to update
3563 ap_config.h. [Brian Havard]
3565 *) The Perl %ENV hash will now be setup by default when using the
3566 mod_include `perl' command [Doug MacEachern]

3580 Changes with Apache 1.3.2
3582 *) Fix bug in ap_remove_module(), which caused problems for dso's
3583 who were the top_module. [Doug MacEachern]
3585 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
3586 mod_auth_db to both be friendly to users who wants to use this version
3587 and to avoid problems under platforms where only version 2.x is present.
3588 [Dan Jacobowitz <drow@false.org>, Ralf S. Engelschall]
3590 *) When using ap_log_rerror(), make the error message available to the
3591 *ERROR_NOTES envariables by default. [Ken Coar]
3593 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
3594 You now must define a BS2000Account name for the server User.
3595 This has fewer security implications than the old approach.
3598 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
3599 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
3600 platform to make the braindead HPUX linker happy. Notice, for the module
3601 DSOs we don't have to use this, because these are loaded manually (and
3602 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
3604 *) Remove 64 thread limit on Win32.
3605 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3607 *) Remove redundant substitutions in top-level Makefile.tmpl.
3608 [Ralf S. Engelschall]
3610 *) Fix APACI's `Group' configuration adjustment - especially for Linux
3611 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
3613 *) Make PrintPath work generically instead of having one version
3614 strictly for OS/2. [Jim Jagielski, Brian Havard]
3616 *) Fix the recently introduced C header file checking: We now use the C
3617 pre-processor pass only (and no longer the complete compiler pass) to
3618 determine whether a C header file exists or not. Because only this way
3619 we're safe against inter-header dependencies (which caused horrible
3620 portability problems). The only drawback is that we now have a CPP
3621 configuration variable which has to be determined first (we do a similar
3622 approach as GNU Autoconf does here). When all fails the user still has
3623 the possibility to override it manually via APACI or src/Configuration.
3624 As a fallback for the header check itself we can directly check the
3625 existance of the file under /usr/include, too.
3626 [Ralf S. Engelschall] PR#2777
3628 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined
3629 as an alternate mechanism for mmap'd shared memory for RHAPSODY.
3630 ap_private_extern defined to hide symbols that conflict with loaded
3631 dynamic libraries on the NEXT and RHAPSODY platforms.

3650 used -lprot. It's actually a bug in SCO5, of course.

3653 *) Fix documentation of ProxyPass/ProxyPassReverse according to the
3654 trailing slash problem. [Jon Drukman <jsd@gamespot.com>] PR#2933
3656 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
3657 platform, because it's only supported under version 4.0 and higher. But
3658 because our GuessOS is still unaware of Digital UNIX versions and the
3659 -msym is just to optimize the DSO statup time a little bit it's safe and
3660 best when we leave it out now. [Ralf S. Engelschall] PR#2969
3662 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
3663 functions: First all three functions no longer fail on strings containing
3664 "%" chars and second ap_log_printf() no longer does a double-formatting
3665 (instead it directly passes through the message to be formatted to the
3666 real internal formatting function). [Ralf S. Engelschall] PR#2941
3668 *) Allow "Include" directives anywhere in the server config
3669 files (but not .htaccess files). [Ken Coar] PR#2727
3671 *) The proxy was refusing to serve CONNECT requests except to
3672 port 443 (https://) and 563 (snews://). The new AllowCONNECT
3673 directive allows the configuration of the ports to which a
3674 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
3676 *) mod_expires will now act on content that is not sent from a file
3677 on disk. Previously it would never add an Expires: header to
3678 any response that did not come from a file on disk; the only
3679 case where it still doesn't (and can't) add one for that type of
3680 content is if you are using a modification date based setting.
3681 [Marc Slemko, Paul Phillips <paulp@go2net.com>]
3683 *) Problems encountered during .htaccess parsing or CGI execution
3684 that lead to a "500 Server Error" condition now provide explanatory
3685 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
3688 *) Add NameWidth keyword to IndexOptions directive so that the
3689 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
3692 *) Recognize lowercase _and_ uppercase `uname' results under
3693 SCO OpenServer. [David Coelho <drc@ppt.com>]
3695 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
3696 a common problem of (mis-administrated?) IIS servers, make the apache
3697 proxy immune to these errors (and ignore the duplicates, but log
3698 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
3700 *) The <IfModule and <IfDefine block starting directives now only
3701 allow exactly one argument. Previously, the optional negation
3702 character '!' could be separated by whitespace without a syntax
3703 error being reported, albeit defeating the IfModule functionality
3704 (enclosed directives would ALWAYS be executed). By using the
3705 stricter syntax, these hard-to-track errors can be avoided.
3708 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
3709 cause the standalone FancyIndexing directive to logically OR
3710 into any existing IndexOptions settings rather than wiping
3711 them out. [Ken Coar]
3713 *) Changes in ftp proxy: make URL parsing simpler by using the
3715 + Add display of the "current directory" in cases where it's
3716 different from the supplied path (e.g., ftp://user@host/ lives
3717 in /home/user, not in /, therefore clicking on "../" in the
3718 starting directory might send us to /home/).
3719 + When ftp login fails, (esp. when a user name was part of the
3720 URL already), we now return [401 Unauthorized ] to allow the
3721 browser to pop up an authorization dialog. This makes passwords
3722 slightly less visible (they don't appear in the regular log files)
3723 and implements a functionality that other www proxy servers
3727 *) Triggered by the recent "Via:" header changes, the proxy module would
3728 dump core for replies with invalid headers (e.g., duplicate
3729 "HTTP/1.0 200 OK" lines). These errors are now logged and the
3730 core dump is avoided. Also, broken replies are not cached.
3731 [Martin Kraemer] PR#2914
3733 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
3734 plop gmon.out profile data for each child [Doug MacEachern]
3736 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
3737 config.status script to be immune against arguments with whitespaces.
3738 [Yves Arrouye <yves@apple.com>] PR#2866
3740 *) Replace the inlined information grabbing stuff for the configuration
3741 adjustment feature (no --without-confadjust) with calls to a new helper
3742 script `buildinfo.sh' which is both more flexible and already proofed to
3743 be more robust against platform differences. This mainly fixes the
3744 recently occured ``sed: command garbled: ...'' problems.
3745 [Ralf S. Engelschall] PR#2776, PR#2848
3747 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
3748 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
3749 without complains after we recently added the POST feature.
3750 [Ralf S. Engelschall]
3752 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
3753 modules as API functions and we forgot them at the big symbol renaming.
3754 [Ralf S. Engelschall]
3756 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html

3762 *) Add the ability to do POST requests to the ab benchmarking tool.
3763 [Kurt Sussman <kls@best.com>] PR#2871
3765 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
3766 5 to 10 because there are some users out there who always have 5 to 8
3767 variables in one RewriteRule and had to patch mod_rewrite.h for every
3768 release. So 15 should be now more than enough, even for them. (I never
3769 needed more than 4 in my RewriteRules ;-)
3770 [Ralf S. Engelschall]
3772 *) Make the proxy generate and understand Via: headers
3775 *) Change the proxy to use tables instead of array_headers for
3776 the header lines. [Martin Kraemer]
3778 *) Make sure the config.status file is not overridden when just
3779 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
3781 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
3782 provide a way to trace API changes that add functionality but do
3783 not create a compatibility issue for precompiled modules, etc.
3784 See include/ap_mmn.h for more details. [Randy Terbush]
3786 *) Fix suexec installation under `make install root=xxx' situation.
3787 [Ralf S. Engelschall]
3789 *) Extend the output of the -V switch to include the paths of all
3790 compiled-in configuration files, if they were overridden at
3791 compile time, for least astonishment of the user.
3794 *) When READing a request in ExtendedStatus mode, the "old"
3795 vhost, request and client information is not displayed.
3798 *) STATUS is no longer available. Full status information now
3799 run-time configurable using the ExtendedStatus directive.
3802 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
3803 cpu time attacks) in header parsing. Add ap_overlap_tables(),
3804 a function which can be used to perform bulk update operations
3805 on tables in a more efficient manner. [Dean Gaudet]
3807 *) SECURITY: Added compile-time and configurable limits for
3808 various aspects of reading a client request to avoid some simple
3809 denial of service attacks, including limits on maximum request-line
3810 size (LimitRequestLine), number of header fields (LimitRequestFields),
3811 and size of any one header field (LimitRequestFieldsize). Also added
3812 a configurable directive LimitRequestBody for limiting the size of the
3813 request message body. [Roy Fielding]
3815 *) Make status module aware of DNS and logging states, even if
3816 STATUS not defined. [Jim Jagielski]
3818 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
3820 *) Enhance mod_speling so that CheckSpelling can be used in

3828 *) API: scan_script_header_err_core() now "public" and renamed
3829 ap_scan_script_header_err_core() [Doug MacEachern]
3831 *) The 'status' module will now show the process pid's and their
3832 state even without full STATUS accounting. [Jim Jagielski]
3834 *) Restore the client IP address to the error log messages, this
3835 was lost during the transition from 1.2 to 1.3. Add a new
3836 function ap_log_rerror() which takes a request_rec * and
3837 formats it appropriately. [Dean Gaudet] PR#2661
3839 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
3840 whitespace in input lines -- including within quoted strings.
3842 but leading and trailing whitespace should continue to be
3843 stripped [Martin Kraemer]
3845 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
3846 the ugly use of an env. variable and use command-line args for
3847 alternate $PATH. Make more like advanced 'type's as well.
3850 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
3851 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis

3863 This is done by determining a subset of LIBS which can be safely used for
3864 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
3865 disabled for all platforms to avoid problems with this (experimental)
3866 rule. But we provide it now for those people how ran into problems and
3867 want to came out by forcing linking against DSOs.

4179 than strcmp() to check for parent directory-ness of an entry. Oh, and
4180 make sure the parent directory (if displayed) is *always* listed first
4181 regardless of the sort key. Overall performance winnage should be good
4182 in CPU time, instruction cache, and memory usage, particularly for large

4192 *) Add httpd -t (test) option for running configuration syntax tests only.
4193 If something is broken it complains and exits with a return code
4194 non-equal to 0. This can be used manually by the user to check the Apache
4195 configuration after editing and is also automatically used by apachectl
4196 on (graceful) restart command to make sure Apache doesn't die on restarts
4197 because of a configuration which is now broken since the last (re)start.
4198 This way `apachectl restart' can be used inside cronjobs without having

4346 the past under Win32).
4347 [Ralf S. Engelschall]
4349 *) A few cosmetics and trivial enhancements to APXS to make the
4350 generated Makefile more user friendly. [Ralf S. Engelschall]
4352 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
4353 was updated to use the normal apache error processing, thereby allowing
4354 proxy errors to be treated by ErrorDocument's as well. For this
4355 purpose, a new module-to-core communication variable "error-notes"
4356 was introduced; the proxy (and possibly other modules) communicates
4357 its error text using this variable. Its content is copied to a new
4358 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
4359 The old proxy special error routine ap_proxy_log_uerror()
4360 was replaced by regular ap_log_error() calls, many messages were made
4362 [Martin Kraemer] PR#494, 1259
4364 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
4367 *) Transform the configure message "You need root privileges for suEXEC"
4368 from a fatal error into a (more friendly) warning because the building
4369 ("make") of Apache we can allow, of course. Root privileges are needed
4370 only for the installation step ("make install"). So make sure the
4371 user is aware of this fact but let him proceed as long as he can.
4372 [Ralf S. Engelschall] PR#2288
4374 *) Renamed three more functions to common ap_ prefix which we missed at the
4375 Big Symbol Renaming because they're #defines and not real C functions:
4376 is_default_port(), default_port(), http_method().
4377 [Ralf S. Engelschall]
4379 *) A zero-length name after a $ in an SSI document should cause
4380 just the $ to be in the expansion. This was broken during the
4381 security fixes in 1.2.5. [Dean Gaudet] PR#1921, 2249
4383 *) Call ap_destroy_sub_req() in ap_add_cgi_vars() to reclaim some
4384 memory. [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2252
4386 *) Fix src/support/httpd.exp (DSO export file which is currently only
4387 used under AIX) because of recent changes to function names.
4388 [Ralf S. Engelschall]
4390 Changes with Apache 1.3b7
4392 *) Make sure a MIME-type can be forced via a RewriteRule even when no
4393 substitution takes place, for instance via the following rule:
4394 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
4395 requested by users in the past to force a single script without a .cgi
4396 extension and outside any cgi-bin dirs to be executed as a CGI program.
4397 [Ralf S. Engelschall] PR#2254
4399 *) A fix for protocol issues surrounding 400, 408, and
4400 414 responses. [Ed Korthof]
4402 *) Ignore MaxRequestsPerChild on WIN32. [Brian Behlendorf]
4404 *) Fix discrepancy in proxy_ftp.c which was causing failures when
4405 trying to connect to certain ftpd's, such as anonftpd.
4406 [Rick Ohnemus <rick@ecompcon.com>]
4408 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
4409 logfile instead of fiddling around itself with child spawning stuff.
4410 [Ralf S. Engelschall]
4412 *) Made RefererIgnore case-insensitive.
4414 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
4417 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
4418 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
4421 *) Improve RFC1413 support. [Bob Beck <beck@bofh.ucs.ualberta.ca>]
4423 *) Fix support script `dbmmanage': It was unable to handle some sort
4424 of passwords, especially passwords with "0" chars.
4425 [Ralf S. Engelschall] PR#2242
4427 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
4428 [Ben Laurie] PR#2238
4430 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
4431 library), so CGI handling has been changed to use Win32 native handles
4432 instead of C file descriptors.
4433 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
4435 *) The proxy cache would store an incorrect content-length in the cached
4436 file copy after a cache update. That resulted in repeated fetching
4437 of the original copy instead of using the cached copy.
4438 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
4440 *) The Makefiles assumed that DSO files are build via $(LD). This
4441 is broken for two reasons: First we never defined at least LD=ld
4442 somewhere to make sure this works (it was silently assumed that most Make
4443 provide a built-in LD definition - ARGL!) and second using the generic LD
4444 variable is not the truth. Instead a special variable named LD_SHLIB is
4445 reasonable because although "ld" is usually the default, the command for
4446 building DSO files can be "libtool" or even "cc" on some systems.
4447 [Ralf S. Engelschall]
4449 *) Replace the AddVersionPlatform directive with ServerTokens which
4450 provides for more control over the format of the Server:
4451 header line. SERVER_SUBVERSION is no longer supported;
4452 all module should use the ap_add_version_component()
4453 API function instead. [Jim Jagielski]
4455 *) Support for the NCR MP/RAS 3.0
4456 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
4458 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
4459 not retrieved in src/Configure and thus was not useable.
4460 [Ralf S. Engelschall]
4462 *) Various Makefile consistency cleanups:
4463 - make OSDIR also automatically be relative to src/ like INCDIR
4464 - SUBDIRS is now generated in src/Makefile only and not in
4465 Makefile.config because it is a local define for this location.
4466 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
4467 any Makefile but make sure that at least the "-K inline" is kept in
4469 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
4470 - updated the dependencies theirself
4471 - removed not existing SHLIB variable from "clean" targets
4472 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
4473 already exists and OBJS_PIC are also just plain objects and have not
4474 directly to do with "shared" things. The only difference is that they
4475 contain PIC. So OBJS_PIC is the more canonical name.
4476 - Updated the Makefile-dependency lines for OBJS_PIC
4477 - Removed the Makefile-dependency line in Configure to avoid double
4479 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
4480 of xxx.lo as GNU libtool does with its PIC objects
4481 - reduce local complexity in modules Makefile.tmpl by moving the last
4482 existing target "depend" to the generation section in Configure, too.
4483 - removed the historical $(SPACER) which was used in the past together
4484 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
4485 is no longer needed.
4486 - force the build and run of the gen_xxx programs under main/ as the
4487 first step before building the objects because it looks cleaner
4488 [Ralf S. Engelschall]
4490 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
4493 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
4496 *) WIN32: Don't force ISAPI headers to finish with \n.
4497 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
4499 *) When opening "configuration" files (like httpd.conf, htaccess
4500 and htpasswd), Apache will not allow them to be non-/dev/null
4501 device files. This closes a DoS hole. At the same time,
4502 we use ap_pfopen to open these files to handle timeouts.
4503 [Jim Jagielski, Martin Kraemer]
4505 *) Apache will now log the reason its httpd children exit if they exit
4506 due to an unexpected signal. (It requires a new porting define,
4507 SYS_SIGLIST, which if defined should point to a list of text
4508 descriptions of the signals available. See PORTING.) [Dean Gaudet]
4510 *) WIN32: chdir() doesn't make sense in a multithreaded environment
4511 like WIN32. Before, Win32 CGI's could have had sporadic failures
4512 if a chdir call from one thread was made between another chdir call
4513 and a spawn in another thread. So, for now don't chdir for CGI scripts
4514 in WIN32. The current CGI "spec" is unclear as to whether it's
4515 necessary. Long-term fix is to either serialize the chdir/spawn combo
4516 or use WIN32 native calls to spawn a process. This temp fix was
4517 necessary to remove this as a showstopper for 1.3's release.
4520 *) Cleanup the suEXEC support in APACI and make it more safe:
4521 1. Add big fat hint in INSTALL about risks and to read the
4522 htdocs/manual/suexec.html document before using the suexec-related
4524 2. Make sure the user has at least provided one --suexec-xxxx option
4525 (specifies suEXEC parameters) in addition to --enable-suexec option.
4526 If only --enable-suexec is given APACI stops with a hint to INSTALL
4527 and htdocs/manual/suexec.html documents.
4528 3. Provide two additional --suexec-xxxx options to make the suEXEC
4529 configuration complete (especially for package maintainers who else
4530 had to patch the source tree) by providing ways to configure minimal
4531 UID/GID and safe PATH, too.
4532 [Ralf S. Engelschall]
4534 *) Cleanup of the `configure --shadow' process:
4535 - make sure the configure script creates its temporary files in the
4536 shadow tree to avoid conflicts with parallel configure runs
4537 - removed unnecessary option "-r" from "rm" call for Makefiles
4538 - make sure the configure scripts creates the shadow-wrapper Makefile
4539 only when no shadow trees already exists
4540 - make sure "make distclean" removes the shadow-wrapper Makefile but only
4541 when no more shadow trees exists
4542 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
4543 as fast (in the past it needed 70sec, now it runs just 38sec)
4544 - make sure CVS does not complain about the created files
4545 Makefille.<gnutriple> and directories src.<gnutriple>
4546 [Ralf S. Engelschall]
4548 *) Added the ap_add_version_component() API routine and the
4549 AddVersionPlatform core directive. The first allows modules to
4550 declare themselves in the Server response header field value,
4551 augmenting the SERVER_SUBVERSION define in the Configuration file
4552 with run-time settings (more useful in a loadable-module environment).
4553 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
4554 into the server version string. [Ken Coar] PR#2056
4556 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
4559 *) Emit the "Accept-Range" header for the default handler.
4560 [Brian Behlendorf] PR#1464
4562 *) Add a note to httpd.conf-dist that apache will on some systems fail
4563 to start when the Group # is set to a negative or large positive value.
4566 *) Make sure the module execution order is correct even when some modules
4567 are loaded under runtime (`LoadModule') via the DSO mechanism:
4568 1. The list of loaded modules is now a dynamically allocated one
4569 and not the original statically list from modules.c
4570 2. The loaded modules are now correctly setup by LoadModule for
4571 later use by the AddModule command.
4572 3. When the DSO mechanism for modules is used APACI's `install'
4573 target now enables all created `LoadModule' lines per default because
4574 this is both already expected by the user _and_ needed to avoid
4575 confusion with the next point and reduces the Makefile.tmpl complexity
4576 4. When the DSO mechanism for modules is used, APACI's `install'
4577 target now additionally makes sure the module list is reconstructed
4578 via a complete `ClearModuleList+AddModule...' entry.
4579 5. The support tool `apxs' now also makes sure an AddModule command
4580 is added in addition to the LoadModule command.
4581 6. The modules.c generation was extended to now contain two
4582 comments to make sure no one is confused by the confusing terminology
4583 of loading/linking (we use load=link+load & link=activate instead of
4584 the obvious load=activate & link=link :-( )
4585 This way now there is no longer a difference under execution time between
4586 statically and dynamically linked modules.
4587 [Ralf S. Engelschall]
4589 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
4590 Big Symbol Renaming. [Ralf S. Engelschall]
4592 *) Add a comment to mod_example.c showing the format of a FLAG command
4595 *) Standardized the time format in mod_status to match that of other
4596 places in the code (e.g. DATE_GMT). PR#1551
4598 *) Fix handling of %Z in timefmt strings for those platforms with no time
4599 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
4602 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
4603 feature compatible with 'UseCanonicalName off' by changing
4604 r->server->server_hostname to ap_get_server_name(). And I changed some
4605 functions which use r->server->port to use ap_get_server_port() instead,
4606 because if there's no Port directive in the config r->server->port is 0.
4609 *) get/set_module_config are trivial enough to be better off inline. Worth
4610 1.5% performance boost. [Dean Gaudet]
4612 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
4613 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
4616 *) [BS2000 security] BS2000 needs an extra authentication to initialize
4617 the task environment to the unprivileged User id. Otherwise CGI scripts
4618 would have a way to gain super user access. [Martin Kraemer]
4620 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
4621 absolute path, only log base name of logging source as is done
4622 in unix. [Martin Kraemer]
4624 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
4625 the encoding type from the Accept-Encoding header (if it's there)
4626 and use it in the response, as that's probably what it'll be expecting.
4627 [Ronald.Tschalaer@psi.ch]
4629 *) Fix to mod_alias: translate_alias_redir is dealing with
4630 a URI, not a filename, so the check for drive letters for win32
4631 and emx is not necessary. [Dean Gaudet]
4633 *) WIN32: Allow .cmd as an executable extension.
4634 [Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146
4636 *) Make Apache header files, and some variables, C++ friendly.
4637 [Michael Anderson's <mka@redes.int.com.mx>]
4639 *) Child processes can now "signal" (by exiting with a status
4640 of APEXIT_CHILDFATAL) the parent process to abort and
4641 shutdown the server if the error in the child process was
4642 fatal enough. [Jim Jagielski]
4644 *) mod_autoindex's find_itme() was sensitive to MIME type case.
4645 [Jim Jagielski] PR#2112
4647 *) Make sure the referer_log and agent_log entries in the default httpd.conf
4648 file are also adjusted for the actual relative installation paths.
4649 [Ralf S. Engelschall] PR#2175
4651 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
4653 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
4656 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
4657 Additionally the checks for finding the vendor DSO library were moved
4658 from mod_so.c to Configure because first it needs $PLAT etc. and second
4659 mod_so already uses an abstraction layer and does not fiddle with the
4660 vendor functions itself.
4661 [Jens-Uwe Mager, Ralf S. Engelschall]
4663 *) PORT: Some optimization defines for NetBSD
4664 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
4666 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
4667 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
4669 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
4670 AIX variants should work fine, too. Even AIX 3.x should work). This is
4671 accomplished by using the free DSO emulation code from Jens-Uwe Mager
4672 which we put into a os/unix/os-dso-aix.c file.
4673 [Ralf S. Engelschall]
4675 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
4676 that we should use NET_SIZE_T == int but the include files force size_t.
4677 [Ralf S. Engelschall]
4679 *) Fix two bugs in select() handling in http_main.c.
4682 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
4683 is unset (as it is in situations like timeouts) where it is unclear
4684 whether errno is set or not. [Martin Kraemer]
4686 *) Just having APACI's localstatedir is too general and not enough for most
4687 of the systems. 1.3b6 again required manual APACI patches by package
4688 maintainers from RedHat and FreeBSD because for their filesystem layout a
4689 little bit more flexibility in configuring the paths is needed. Hence we
4690 provide three additional configure options (--runtimedir, --logfiledir,
4691 --proxycachedir) which now can be used for more granular adjustments if
4692 --localstatedir is not enough to fit the particular needs. As a nice
4693 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
4694 [Ralf S. Engelschall]
4696 *) Make the install root for "make install" in APACI's Makefile overrideable
4697 by package authors. This way we are even more friendly to package
4698 maintainers (especially Debian and RedHat) who build for the real prefix
4699 via "configure --prefix=/<real>" but use a different local prefix via
4700 "make root=/tmp/apache install" for rolling the package without bristling
4701 the target location on their system.
4702 [Ralf S. Engelschall]
4704 *) Workaround sed limitations in APACI's configure script by now
4705 substituting in chunks of 50 commands (because for instance HPUX's vendor
4706 sed has a limit of max. 98 commands)
4707 [Ralf S. Engelschall] PR#2136
4709 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
4710 [Ralf S. Engelschall] PR#2140
4712 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
4713 RENAMING process because they are defined as pre-processor macros instead
4714 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
4715 [Ralf S. Engelschall]
4717 *) Workaround braindead AWK's when generating ap_config.h: The split() and
4718 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
4719 [Ralf S. Engelschall] PR#2139
4721 *) Various bugfixes and cleanups for the APACI configure script:
4722 o fix IFS handling for _nested_ situation
4723 o fix Perl interpreter search: take first one found instead of last one
4724 o fix DSO consistency check
4725 o print error messages to stderr instead of stdout
4726 o add install-quiet for --shadow situation to Makefile stub
4727 o reduce complexity by avoiding sed-hacks for rule and module list loops
4728 [Ralf S. Engelschall]
4730 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
4732 *) Make sure the input field separator (IFS) shell variable is explicitly
4733 initialized correctly before _every_ `for' loop and also restored after
4734 the loops. [Ralf S. Engelschall]
4736 *) Make sure that "make install" doesn't overwrite the `mime.types' and
4737 `magic' files from an existing Apache installation. Because people often
4738 customize these for own MIME and content types.
4739 [Ralf S. Engelschall]
4741 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
4742 [Peter Galbavy, Ralf S. Engelschall] PR#2109
4744 *) Fix the path to the ScoreBoardFile in the install-config target, too.
4745 [Ralf S. Engelschall] PR#2105
4747 *) Let "configure" clear out the users parameters (provided as shell
4748 variables) to avoid side-effects in "src/Configure" when the user
4749 exported them (which is not needed, but some users do it).
4750 [Ralf S. Engelschall] PR#2101
4752 *) Provide backward compatibility from some old src/Configuration.tmpl
4753 parameter names to the canonical Autoconf-style shell variable names. For
4754 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
4755 but a hint message is displayed. [Ralf S. Engelschall]
4757 *) Make sure that "make install" doesn't overwrite the DocumentRoot and
4758 CGI scripts from an existing Apache installation.
4759 [Ralf S. Engelschall, Jim Jagielski] PR#2084
4761 *) Make `configure --compat' more "compatible" by first
4762 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
4763 second by making sure the "avoid-bristling-suffix" /apache is not
4764 appended to sysconfdir, datadir, localstatedir and includedir when
4765 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]
4767 *) NeXT required strdup() in support/logresolve.c
4768 [Francisco Tomei <fatomei@sandburg.unm.edu>] PR#2082
4770 *) AIX required sys/select.h in support/ab.c
4771 [Jens Schleusener <Jens.Schleusener@dlr.de>] PR#2081
4773 *) Fix the path to the MimeMagicFile in the install-config target, too.
4774 [Ralf S. Engelschall] PR#2089
4776 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
4778 *) If you start apache with the -S command line option it will dump
4779 out the parsed vhost settings. This is useful for folks trying
4780 to figure out what is wrong with their vhost configuration.
4781 (Other dumps may be added in the future.) [Dean Gaudet]
4783 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
4784 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
4787 *) Because /usr/local/apache is the default prefix the ``configure
4788 --compat'' option no longer has to set prefix, again. This way the
4789 --compat option honors a leading --prefix option. [Lars Eilebrecht]
4791 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
4792 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
4793 to avoid "discard const" warnings. [Ralf S. Engelschall]
4795 *) If a specific handler is set for a file yet the request still
4796 ends up being handled by the default handler, log an error
4797 message before handling it. This catches things such as trying
4798 to use SSIs without mod_include enabled. [Marc Slemko]
4800 *) Fix error logging for the startup case where ap_log_error() still uses
4801 stderr as the target. Now the default log level is honored here, too.
4802 [Ralf S. Engelschall]
4804 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
4805 long" errors when generating the MODULES entry for src/Makefile
4806 [Ben Hyde, Ralf S. Engelschall]
4808 *) Make sure src/Configure doesn't complain about the old directory
4809 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
4811 Changes with Apache 1.3b6
4813 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
4815 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
4816 interface via the similar but proprietary HP/UX shl_xxx-style system
4817 calls. [Ralf S. Engelschall]
4819 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
4820 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
4821 Make. [Ralf S. Engelschall]
4823 *) ++++ THE BIG SYMBOL RENAMING ++++
4824 To avoid symbol clashes with third-party code compiled into the server,
4825 we globally applied the prefix "ap_" to the following classes of
4827 - Apache provided general functions (e.g., ap_cpystrn)
4828 - Public API functions (e.g., palloc, bgets)
4829 - Private functions which we can't make static (because of
4830 cross-object usage) but should be (e.g., new_connection)
4831 For backward source compatibility a new header file named compat.h was
4832 created which provides defines for the old symbol names and can be used
4833 by third-party module authors.
4836 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
4837 problem under SVR4 is that there is no command flag to force the linker
4838 to export the global symbols of the httpd executable therewith they are
4839 available to the DSO's. Instead of problematic hacks like creating a
4840 dummy.so file (containing dummy references to all global symbols) the
4841 httpd binary is linked against, we use a clean trick stolen from Perl 5:
4842 Placing the Apache core code itself into a DSO library named libhttpd.so.
4843 This way the global symbols _HAVE_ to be exported and thus are available
4844 to any manually loaded DSO's under runtime. To reduce the impact to the
4845 user to null we go even further and create a stub httpd executable which
4846 automatically keeps track of the DSO library loading itself and thus
4847 hides the complete mechanism from the user. Although the generation of
4848 this DSO library is automatically triggered for platforms which
4849 essentially need it (mostly all SVR4-derivates) it can be also enabled
4850 manually via the Rule SHARED_CORE. This can be interesting in the future
4851 where we perhaps exploit this libhttpd.so mechanism for providing nifty
4852 features like graceful upgrades, or whatever.
4853 [Ralf S. Engelschall, Martin Kraemer]
4855 *) Build the libraries before building the rest of the tools. [Ben Hyde]
4857 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
4858 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
4859 conventions while "clean" removes only stuff created by "all" targets,
4860 "distclean" additionally removes the stuff from the configuration
4861 process. This way "make distclean" (hence the name) provides a fresh
4862 source tree as it was for distribution.
4863 [Ralf S. Engelschall]
4865 *) Allow top-level (APACI) Makefile to break on build errors
4866 the same way the src/ subtree Makefiles breaks on them by replacing the
4867 initial APACI sed-subdir-display-kludge with a more clean
4868 variable-passing-solution: variable SDP can optionally hold the subdir
4869 prefix which is consistently used for displaying the subdir movement.
4870 This way even the top-level Makefile can stop correctly on errors as the
4871 user expects. [Ralf S. Engelschall]
4873 *) Fixed ordering of argument checks for RewriteBase directive.
4874 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
4876 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
4877 indicating that a module is being compiled for dynamic loading. Also
4878 remove #define IS_MODULE from modules and add SHARED_MODULE define
4879 to the mak/dsp files. [Alexei Kosut]
4881 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
4882 since we are now logging APLOG_WARNING by default. [Roy Fielding]
4884 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
4886 *) Add documentation file and src/Configuration.tmpl entry for the
4887 experimental mod_mmap_static module. Because although it is and marked as
4888 an experimental one it is distributed and thus should be documented and
4889 prepared for configuration the same way as all others modules.
4890 [Ralf S. Engelschall]
4892 *) Add query (-q) option to apxs support tool to be able to manually query
4893 specific settings from apxs. This is needed for instance when you
4894 manually want to access Apache's header files and you need to assemble
4895 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
4896 [Ralf S. Engelschall]
4898 *) Now src/Configure uses a fallback strategy for the shared object support
4899 on platforms where no explicit information is available: If a Perl
4900 installation exists we ask it about its shared object support and if it's
4901 the dlopen-style one we shamelessly guess the compiler and linker flags
4902 for creating shared objects from Perls knowledge. Of course, the user is
4903 warning about what we are doing and informed that he should send us
4904 the guessed flags when they work. [Ralf S. Engelschall]
4906 *) Provide APACI --without-support option to be able to disable the build
4907 and installation of the support tools from the src/support/ area.
4908 Although its useful to have these installed per default we should provide
4909 a way to compile and install without them for backward-compatibility.
4910 [Ralf S. Engelschall]
4912 *) Add of the new APache eXtenSion (apxs) support tool for building and
4913 installing modules into an _already installed_ Apache package through the
4914 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
4915 this approach actually doesn't need the Apache source tree. The
4916 (APACI-installed) server package is enough, because this now includes the
4917 Apache C header files (PREFIX/include) and the new APXS tool
4918 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
4919 module authors to build their Apache modules _OUTSIDE_ the Apache source
4920 tree while avoiding them to fiddle around with the totally platform
4921 dependend way of compiling DSO files. The tool supports all ranges of
4922 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
4923 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
4924 on-the-fly generate a minimalistic Makefile and sample module for the
4925 first step to provide both a quick success event and to demonstrate the
4926 APXS mechanism to module authors. [Ralf S. Engelschall]
4928 *) Fix core dumps in use of CONNECT in proxy.
4929 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
4931 *) Modify the log directives in httpd.conf-dist files to use CustomLog
4932 so that users have examples of how CustomLog can be used.
4935 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
4936 the Apache distribution tree. Until Apache 1.3 there was no real
4937 out-of-the-box batch-capable build and installation procedure for the
4938 complete Apache package. This is now provided by a top-level "configure"
4939 script and a corresponding top-level "Makefile.tmpl" file. The goal is
4940 to provide a GNU Autoconf-style frontend which is capable to both drive
4941 the old src/Configure stuff in batch and additionally installs the
4942 package with a GNU-conforming directory layout. Any options from the old
4943 configuration scheme are available plus a lot of new options for flexibly
4944 customizing Apache. [Ralf S. Engelschall]
4946 *) The floating point ap_snprintf code wasn't threadsafe.
4947 Had to remove the HAVE_CVT macro in order to do threadsafe
4948 calling of the ?cvt() floating point routines. [Dean Gaudet]
4950 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
4952 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
4953 [Jim Jagielski] PR#1901
4955 *) BUG: Configure was using TCC and CC inconsistently. Make sure
4956 Configure knows which CC we are using. [Jim Jagielski]
4958 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
4959 was defined in a parent directory. [Lars Eilebrecht]
4961 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
4962 a generic printf-style routine that can call arbitrary output
4963 routines. Use this to replace http_bprintf.c. Add new routines
4964 psprintf(), pvsprintf() which allocate the exact amount of memory
4965 required for a string from a pool. Use psprintf() to clean up
4966 various bits of code which used ap_snprintf()/pstrdup().
4969 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
4970 ap_snprintf() has different semantics and formatting codes than
4971 snprintf(). [Dean Gaudet]
4973 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
4974 is necessary on at least Solaris where the /etc/rc?.d scripts
4975 are run with these signals ignored, and "SIG_IGN" settings are
4976 maintained across exec().
4977 [Rein Tollevik <reint@sys.sol.no>] PR#2009
4979 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
4980 used instead of lstat() and thus this flag didn't work as expected.
4981 [Rein Tollevik <reint@sys.sol.no>] PR#2010
4983 *) Fix the proxy pass-through feature of mod_rewrite for the case of
4984 existing QUERY_STRING now that mod_proxy was recently changed because of
4985 the new URL parsing stuff. [Ralf S. Engelschall]
4987 *) A few changes to scoreboard definitions which helps gcc generate
4988 better code. [Dean Gaudet]
4990 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
4991 be a signed bitfield. So mark a few bitfields as signed to
4992 ensure correct code. [Dean Gaudet]
4994 *) The default for HostnameLookups was changed to Off, but there
4995 was a problem and it wasn't taking effect. [Dean Gaudet]
4997 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
5000 *) After a SIGHUP the listening sockets in the parent weren't
5001 properly marked for closure on fork().
5002 [Jürgen Keil <jk@tools.de>] PR#2000
5004 *) Allow %2F in two situations: 1) it is in the query part of the URI,
5005 therefore not exposed to %2F -> '/' translations and 2) the request
5006 is a proxy request, so we're not dealing with a local resource anyway.
5007 Without this, the proxy would fail to work for any URL's with
5008 %2f in them (occurs quite often in
5009 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
5011 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
5013 *) Make the shared object compilation command more portable by avoiding
5014 the direct combination of `-c' & `-o' which is not honored by some
5015 compilers like UnixWare's cc. [Ralf S. Engelschall]
5017 *) WIN32: the proxy was creating filenames missing the last four
5018 characters. While this normally doesn't stop anything from
5019 working, it can result in extra collisions.
5020 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
5022 *) Now mod_proxy uses the response string (in addition to the response status
5023 code) from the already used FTP SIZE command to setup the Content-Length
5024 header if available. [Ralf S. Engelschall] PR#1183
5026 *) Reanimated the (still undocumented) proxy receive buffer size directive:
5027 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
5028 name was really too generic, added documentation for this directive to
5029 the mod_proxy.html and corrected the hyperlink to it in the
5030 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
5032 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
5033 faster [Martin Kraemer]
5035 *) Make Configure die when you give it an unknown command switch.
5038 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
5039 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
5040 and per default compiled support programs have manual pages - just to
5041 document our stuff a little bit more and to be able to do really
5042 Unix-like installations ;-) [Ralf S. Engelschall]
5044 *) Major cleanups to the Configure script to make it and its generated
5045 Makefiles again readable and maintainable: add SRCDIR option, removed
5046 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
5047 generated sections, consequently added Makefile headers with inheritance
5048 information, added subdir movement messages for easier following where
5049 the build process currently stays (more verbose then standard Make, less
5050 verbose than GNU make), same style to comments in the Configure script,
5051 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
5053 *) Add the new ApacheBench program "ab" to src/support/: This is derived
5054 from the ZeusBench benchmarking program and can be used to determine the
5055 response performance of an Apache installation. This version is
5056 officially licensed with Zeus Technology, Ltd. See the license agreement
5057 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
5058 [Ralf S. Engelschall]
5060 *) API: Various core functions that are definately not part of the API
5061 have been made static, and a few have been marked API_EXPORT. Still
5062 more have been marked CORE_EXPORT and are not intended for general
5063 use by modules. [Doug MacEachern, Dean Gaudet]
5065 *) mod_proxy was not clearing the Proxy-Connection header from
5066 requests; now it does. This did not violate any spec, however
5067 causes poor interactions when you are talking to remote proxies.
5068 [Marc Slemko] PR#1741
5070 *) Various cleanups to the command line interface and manual pages.
5071 [Ralf S. Engelschall]
5073 *) cfg_getline() was not properly handling lines that did not end
5074 with a line termination character. [Marc Slemko] PR#1869, 1909
5076 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
5078 *) Clean up some undocumented behavior of mod_setenvif related to
5079 "merging" two SetEnvIf directives when they match the same header
5080 and regex. Document that mod_setenvif will perform comparisons in
5081 the order they appear in the config file. Optimize mod_setenvif by
5082 doing more work at config time rather than at runtime.
5085 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
5086 to allow for modules to overrule them and to reduce redefinition
5087 warnings [Jim Jagielski]
5089 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
5092 *) Making the hard-coded cross-module function call mime_find_ct() (from
5093 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
5094 checking is really called even for proxy requests except for URLs with
5095 HTTP schemes (because there we can optimize by not running the type
5096 checking hooks due to the fact that the proxy gets the MIME Content-type
5097 from the remote host later). This change cleans up mod_mime by removing
5098 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
5099 especially unbundles mod_proxy and mod_mime. This way they both now can
5100 be compiled as shared objects and are no longer tied together.
5101 [Ralf S. Engelschall]
5103 *) util.c cleanup and speedup. [Dean Gaudet]
5105 *) API: Clarification, pstrndup() will always copy n bytes of the source
5106 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
5108 *) Mark module command_rec and handler_rec structures const so that they
5109 end up in the read-only data section (and are friendlier to systems
5110 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
5112 *) Add check to the "Port" directive to make sure the specified
5113 port is in the appropriate range. [Ben Hyde]
5115 *) Performance improvements to invoke_handler().
5116 [Dmitry Khrustalev <dima@bog.msu.su>]
5118 *) Added support for building shared objects even for library-style modules
5119 (which are built from more than one object file). This now provides the
5120 ability to build mod_proxy as a shared object module. Additionally
5121 modules like mod_example are now also supported for shared object
5122 building because the generated Makefiles now no longer assume there is at
5123 least one statically linked module. [Ralf S. Engelschall]
5125 *) API: Clarify usage of content_type, handler, content_encoding,
5126 content_language and content_languages fields in request_rec. They
5127 must always be lowercased; and the strings pointed to shouldn't
5128 be modified (you must copy them to modify them). Fix a few bugs
5129 related to this. [Dean Gaudet]
5131 *) API: Clarification: except for RAW_ARGS, all command handlers can
5132 treat the char * parameters as permanent, and modifiable. There
5133 is no need to pstrdup() them. Clean up some needless pstrdup().
5136 *) Now mod_so keeps track of which module shared objects with which names
5137 are loaded and thus avoids multiple loading and unloading and irritating
5138 error_log messages. [Ralf S. Engelschall]
5140 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
5141 environment variable in the apache core. But that tweaking interferes
5142 with mod_setenv. So don't tweak if the user has specified an explicit
5143 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
5145 *) rputs() did not calculate r->sent_bodyct properly.
5146 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
5148 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
5149 name, or left unset if this value is unavailable. Apache was setting
5150 it to the IP address when unavailable.
5151 [Tony Finch <fanf@demon.net>] PR#1925
5153 *) Various improvements to the configuration and build support for compiling
5154 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
5155 OSF1 support with GCC and vendor compilers was added. This way shared
5156 object support is now provided out-of-the-box for FreeBSD, Linux,
5157 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
5158 [Ralf S. Engelschall]
5160 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
5161 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
5162 and USE_OS2_SCOREBOARD. [Dean Gaudet]
5164 *) Fix one more special locking problem for RewriteMap programs in
5165 mod_rewrite: According to the documentation of flock(), "Locks are on
5166 files, not file descriptors. That is, file descriptors duplicated
5167 through dup(2) or fork(2) do not result in multiple instances of a lock,
5168 but rather multiple references to a single lock. If a process holding a
5169 lock on a file forks and the child explicitly unlocks the file, the
5170 parent will lose its lock.". To overcome this we have to make sure the
5171 RewriteLock file is opened _AFTER_ the childs were spawned which is now
5172 the case by opening it in the child_init instead of the module_init API
5173 hook. [Ralf S. Engelschall] PR#1029
5175 *) Change to Location and LocationMatch semantics. LocationMatch no
5176 longer lets a single slash match multiple adjacent slashes in the
5177 URL. This change is for consistency with RewriteRule and
5178 AliasMatch. Multiple slashes have meaning in URLs that they do
5179 not have in (some) filesystems. Location on the other hand can
5180 be considered a shorthand for a more complicated regex, and it
5181 does match multiple slashes with a single slash -- which is
5182 also consistent with the Alias directive.
5183 [Dean Gaudet] related PR#1440
5185 *) Fix bug with mod_mime_magic causing certain files, including files
5186 of length 0, to result in no response from the server.
5189 *) The Configure script now generates src/include/ap_config.h which
5190 contains the set of defines used when Apache is compiled on a platform.
5191 This file can then be included by external modules before including
5192 any Apache header files in case they are being built separately from
5193 Apache. Along with this change, a couple of minor changes were
5194 made to make Apache's #defines coexist peacefully with any autoconf
5195 defines an external module might have. [Rasmus Lerdorf]
5197 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
5198 but without any RewriteXXXXX directives. Here mod_rewrite is given no
5199 chance by the API to initialize its per-server configuration and thus
5200 receives the wrong one from the main server. This is now avoided by
5201 remembering the server together with the config structure while
5202 configuring and later assuming there is no config when we see a
5203 difference between the remembered server and the one calling us.
5204 [Ralf S. Engelschall] PR#1790
5206 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
5207 is automatically disabled under configure time when the dbm_xxx functions
5208 are not available. Second, two heavy source code errors in the DBM
5209 support code were fixed. This makes DBM RewriteMap's usable again after
5210 a long time of brokenness. [Ralf S. Engelschall] PR#1696
5212 *) Now all configuration files support Unix-style line-continuation via
5213 the trailing backslash ("\") character. This enables us to write down
5214 complex or just very long directives in a more readable way. The
5215 backslash character has to be really the last character before the
5216 newline and it has not been prefixed by another (escaping) backslash.

5228 *) WIN32: Preserve trailing slash in canonical path (and hence
5229 in PATH_INFO). [Paul Sutton, Ben Laurie]
5231 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
5232 depending on the rev of Solaris and what mixture of modules
5233 are in use. So it has been disabled, and Solaris is back to
5234 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
5235 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
5236 up static content only servers. Or it may fail unpredictably.

5239 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
5242 *) API: Rewrite of absoluteURI handling, and in particular how
5243 absoluteURIs match vhosts. Unless a request is a proxy request, a
5244 "http://host" url is treated as if a similar "Host:" header had been
5245 supplied. This change was made to support future HTTP/1.x protocols
5246 which may require clients to send absoluteURIs for all requests.
5248 In order to achieve this change subtle changes were made to the API. In a
5249 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
5250 that the unmodified uri can be retrieved easily. r->proxyreq is not set
5251 by the core, modules must set it during the post_read_request or
5252 translate_names phase.
5254 Plus changes to the virtualhost test suite for absoluteURI testing.
5256 This fixes several bugs with the proxy proxying requests to vhosts
5257 managed by the same httpd.
5260 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
5261 code from mod_rewrite. The vhost matching is now performed by a
5262 globally available function matches_request_vhost(). [Dean Gaudet]

5278 *) API: A new source module main/util_uri.c; It contains a routine
5279 parse_uri_components() and friends which breaks a URI into its component
5280 parts. These parts are stored in a uri_components structure called
5281 parsed_uri within each request_rec, and are available to all modules.
5282 Additionally, an unparse routine is supplied which re-assembles the URI
5283 components back to an URI, optionally hiding the username:password@ part
5284 from ftp proxy requests, and other useful routines. Within the structure,
5285 you find on a ready-for-use basis:
5286 scheme; /* scheme ("http"/"ftp"/...) */
5287 hostinfo; /* combined [user[:password]@]host[:port] */
5288 user; /* user name, as in http://user:passwd@host:port/ */
5289 password; /* password, as in http://user:passwd@host:port/ */
5290 hostname; /* hostname from URI (or from Host: header) */
5291 port_str; /* port string (integer representation is in "port") */
5292 path; /* the request path (or "/" if only scheme://host was given) */
5293 query; /* Everything after a '?' in the path, if present */
5294 fragment; /* Trailing "#fragment" string, if present */
5295 This is meant to serve as the platform for *BIG* savings in
5296 code complexity for the proxy module (and maybe the vhost logic).
5299 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
5300 ${map:key}) available for all location where a string is created in
5301 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of

5316 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause
5317 server to bind to port 0 rather than 80. [Dean Gaudet]
5319 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
5320 (like SunOS and FreeBSD) which don't accept the locking of pipes
5321 directly. A new directive RewriteLock is introduced which can be used to
5322 setup a separate locking file which then is used for synchronization.

5325 *) WIN32: The server root is obtained from the registry key
5326 HKLM\SOFTWARE\Apache Group\Apache\<version> (version is currently

5328 value is stored by running "apache -i -d serverroot". [Paul Sutton]

5337 *) The mod_setenvif BrowserMatch backwards compatibility command did not
5338 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
5340 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
5341 type but with a special post-processing for the looked-up value: It
5342 parses it into alternatives according to `|' chars and then only one
5343 particular alternative is chosen randomly (this is an essential
5344 functionality needed for balancing between backend-servers when using
5345 Apache as a Reverse Proxy. The looked up value here is a list of
5346 servers). Second, `int' with the built-in maps named `tolower' and
5347 `toupper' which can be used to map URL parts to a fixed case (this is an
5348 essential feature to fix the case of server names when doing mass
5349 virtual-hosting with the help of mod_rewrite instead of using
5350 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
5351 Jay Soffian <jay@cimedia.com>] PR#1631
5353 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
5354 This directive lets Apache adjust the URL in Location-headers on HTTP
5355 redirect responses sent by the remote server. This way the virtually
5356 mapped area is no longer left on redirects and thus by-passed which is
5357 especially essential when running Apache as a reverse proxy.

5360 *) Hide Proxy-Authorization from CGI/SSI/etc just like Authorization is
5361 hidden. [Alvaro Martinez Echevarria]

5458 Changes with Apache 1.3b4
5460 *) The module structure was modified to include a *dynamic_load_handle
5461 in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
5462 has been bumped accordingly. [Paul Sutton]
5464 *) All BrowserMatch directives mentioned in
5465 htdocs/manual/known_client_problems.html are in the default
5466 configuration files. [Lars Eilebrecht]
5468 *) MiNT port update. [Jan Paul Schmidt]
5470 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
5471 equivalent, similarly for x-compress and compress. Apache
5472 now ignores a leading x- when comparing encodings. It also
5473 preserves the encoding the client requests (for example if
5474 it requests x-gzip, then Apache will respond with x-gzip
5475 in the Content-Encoding header).

5478 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
5480 *) Added mod_so module to support dynamic loading of modules on Unix
5481 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
5482 instead of AddModule in Configuration to build shared modules
5483 [Sameer Parekh, Paul Sutton]
5485 *) Minor cleanups to r->finfo handling in some modules.
5488 *) Abstract read()/write() to ap_read()/ap_write().
5489 Makes it easier to add other types of IO code such as SFIO.
5492 *) API: Generalize default_port manipulations to make support of
5493 different protocols easier. [Ben Laurie, Randy Terbush]
5495 *) There are many cases where users do not want Apache to form
5496 self-referential urls using the "canonical" ServerName and Port.
5497 The new UseCanonicalName directive (default on), if set to off
5498 will cause Apache to use the client-supplied hostname and port.
5499 API: Part of this change required a change to the construct_url()
5500 prototype; and the addition of get_server_name() and
5502 [Michael Douglass <mikedoug@texas.net>, Dean Gaudet]
5503 PR#315, 459, 485, 1433
5505 *) Yet another rearrangement of the source tree.. now all the common
5506 header files are in the src/include directory. The -Imain -Iap
5507 references in Makefiles have been changed to the simpler -Iinclude
5508 instead. In addition to simplifying the build a little bit, this
5509 also makes it clear when a module is referencing something in a
5510 other than kosher manner (e.g., the proxy including mod_mime.h).
5511 Module-private header files (the proxy, mod_mime, the regex library,
5512 and mod_rewrite) have not been moved to src/include; nor have
5513 the OS-abstraction files. [Ken Coar]
5515 *) Fix a bug where r->hostname didn't have the :port stripped
5516 from it. [Dean Gaudet]
5518 *) Tweaked the headers_out table size, and the subprocess_env
5519 table size guess in rename_original_environment(). Added
5520 MAKE_TABLE_PROFILE which can help discover make_table()
5521 calls that use too small an initial guess, see alloc.c.
5524 *) Options and AllowOverride weren't properly merging in the main
5525 server setting inside vhosts (only an issue when you have no
5526 <Directory> or other section containing an Options that affects
5527 a request). Options +foo or -foo in the main_server wouldn't
5528 affect the main_server's lookup defaults. [Dean Gaudet]
5530 *) Variable 'cwd' was being used pointlessly before being set.
5533 *) r->allowed handling cleaned up in the standard modules.
5536 *) Some case-sensitivity issues cleaned up to be consistent with
5537 RFC2068. [Dean Gaudet]
5539 *) SIGURG doesn't exist everywhere.
5540 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
5542 *) mod_unique_id was erroneously generating a second unique id when
5543 an internal redirect occured. Such redirects occur, for example,
5544 when processing a DirectoryIndex match. [Dean Gaudet]
5546 *) API: table_add, table_merge, and table_set include implicit pstrdup()
5547 of the key and value. But in many cases this is not required
5548 because the key/value is a constant, or the value has been built
5549 by pstrcat() or other similar means. New routines table_addn,
5550 table_mergen, and table_setn have been added to the API, these
5551 routines do not pstrdup() their arguments. The core code and
5552 standard modules were changed to take advantage of these routines.
5553 The resulting server is up to 20% faster in some situations.
5555 Note that it is easy to get code subtly wrong if you pass a key/value
5556 which is in a pool other than the pool of the table. The only
5557 safe thing to do is to pass key/values which are in the pool of
5558 the table, or in one of the ancestors of the pool of the table.
5559 i.e. if the table is part of a subrequest, a value from the main
5560 request's pool is OK since the subrequest pool is a sub_pool of the
5561 main request's pool (and therefore has a lifespan at most as long as
5562 the main pool). There is debugging code which can detect improper
5563 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
5564 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
5566 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
5567 which don't exist on disk more gracefully; handles vhosts properly.
5568 Update documentation to reflect the code -- if there's no
5569 MimeMagicFile directive then the module is not enabled.
5572 *) PORT: Some older *nix dialects cannot automatically start scripts
5573 which begin with a #! interpreter line (the shell starts the scripts
5574 appropriately on these platforms). Apache now supports starting of
5575 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
5576 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
5579 *) API: "typedef array_header table" removed from alloc.h, folks should
5580 have been writing to use table as if it were an opaque type, but even
5581 some standard modules got this wrong. By changing the definition
5582 to "typedef struct table table" module authors will receive compile
5583 time warnings that they're doing the wrong thing. This change
5584 facilitates future changes with more sophisticated table
5585 structures. Specifically, module authors should be using table_elts()
5586 to get access to an array_header * for the table. [Dean Gaudet]
5588 *) API: Renamed new_connection() to avoid namespace collision with LDAP
5589 library routines. [Ken Coar, Rasmus Lerdorf]
5591 *) WIN32: mod_speling is now available on the Win32 platform.
5594 *) For clarity the following compile time definition was changed:
5596 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
5598 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
5599 and not be a general notice that the OS has mmap(). Now the
5600 HAVE_MMAP/SHMGET #defines strictly are informational that the
5601 OS has that method of shared memory; the type to use for
5602 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
5603 and USE_SHMGET_SCOREBOARD). This allows outside modules to
5604 determine if shared memory is available and allows Apache
5605 to determine the best method to use for the scoreboard.
5608 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
5609 as do various earlier versions. It should be safe on all versions.
5610 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
5611 the slack code. A few other cleanups for Unixware.

5614 *) PORT: A/UX can handle single-listen accepts without mutex
5615 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
5617 *) When die() happens we need to eat any request body if one exists.
5618 Otherwise we can't continue with a keepalive session. This shows up
5619 as a POST problem with MSIE 4.0, typically against pages which are
5620 authenticated. [Roy Fielding] PR#1399
5622 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
5623 header will be passed to CGIs. This is generally a security hole, so

5631 *) suexec errors now include the errno/description. [Marc Slemko] PR#1543
5633 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
5634 The choice of flock vs. fcntl was made based on timings which showed that
5635 even on non-NFS, non-exported filesystems fcntl() was an order of
5636 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
5637 that single socket users will see no difference. [Dean Gaudet] PR#467
5639 *) "File does not exist" error message was erroneously including the
5640 errno. [Marc Slemko]
5642 *) Improve the warning message generated when a client drops the

5647 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
5649 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.

5659 *) Some const declarations in mod_imap.c that were added for debugging
5660 purposes caused some compilers heartburn without adding any
5661 significant value, so they've been removed. [Ken Coar]
5663 *) The src/main/*.h header files have had #ifndef wrappers added to
5664 insulate them against duplicate calls if they get included through
5665 multiple paths (e.g., in .c files as well as other .h files).
5668 *) The libap routines now have a header file for their prototypes,
5669 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
5671 *) mod_autoindex with a plaintext header file would emit the <PRE>
5672 start-tag before the HTML preamble, rather than after the preamble
5673 but before the header file contents. [John Van Essen <jve@gamers.org>]
5676 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
5677 only an issue on systems without a MAXDNAME define or where
5678 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
5680 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
5681 is used to read various types of files such as htaccess and
5682 htpasswd files. [Marc Slemko]
5684 *) SECURITY: Ensure that the buffer returned by ht_time is always
5685 properly null terminated. [Marc Slemko]
5687 *) The "Connection" header could be sent back with multiple "close"
5688 tokens. Not an error, but a waste.

5694 *) "basic" auth needs a case-insensitive comparison.
5695 [Ronald.Tschalaer@psi.ch] PR#1666
5697 *) For maximum portability, the environment passed to CGIs should
5698 only contain variables whose names match the regex
5699 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
5700 underscores over any character outside the regex. This
5701 affects HTTP_* variables, in a way that should be backward
5702 compatible for all the standard headers; and affects variables
5703 set with SetEnv/BrowserMatch and similar directives.

5790 [Ben Reser <breser@regnow.com>] PR#1366
5792 *) The bputc() macro was not properly integrated with the chunking
5793 code; in many cases modules using bputc() could cause completely
5794 bogus chunked output. (Typically this will show up as problems
5795 with Internet Explorer 4.0 reading a page, but other browsers
5796 having no problem.) [Dean Gaudet]
5798 *) Create LARGE_WRITE_THRESHOLD define which determines how many
5799 bytes have to be supplied to bwrite() before it will consider
5800 doing a writev() to assemble multiple buffers in one system
5801 call. This is critical for modules such as mod_include,
5802 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
5803 strings in some cases. The result would be extra effort
5804 setting up writev(), and in many cases extra effort building
5805 chunks. The default is 31, it can be overriden at compile

5834 It also wouldn't handle "AddIconByType (TXT,/icons/text.gif text/*"

5837 *) It appears the "257th byte" bug (see

5871 *) WIN32: Cure file leak in CGIs. [Peter Tillemans <pti@net4all.be>] PR#1523

5874 now have a title in which the path components are clickable and allow
5875 quick navigation to the clicked-on directory on the currently listed
5876 ftp server. This also fixes a bug where the ".." directory links would

5915 This turns out to be a bug in Winsock - select() doesn't always
5916 return the correct status. [Ben Laurie]
5918 *) Directives owned by http_core can now use the new check_cmd_context()
5919 routine to ensure that they're not being used within a container
5920 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
5922 *) PORT: Recent changes made it necessary to add explicit prototype
5923 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
5925 *) It was necessary to distinguish between resources which are
5926 allocated in the parent, for cleanup in the parent, and resources
5927 which are allocated in each child, for cleanup in each child.
5928 A new pool was created which is passed to the module child_init
5929 and child_exit functions; modules are free to register per-child
5930 cleanups there. This fixes a bug with reliable piped logs.
5933 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
5934 unless it was also doing FancyIndexes, but it displayed the
5935 HeaderName file at the top under all circumstances. It now shows
5936 the ReadmeName file for simple indices, too, as it should.
5939 *) http_core was mmap()ing even in cases where it wasn't going to
5940 read the file. [Ben Hyde <bhyde@gensym.com>]
5942 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
5943 Now the rewriting engine (the heart of mod_rewrite) is organized more
5944 straight-forward, first time well documented and reduced to the really
5945 essential parts. All redundant cases were stripped off and processing now
5946 is the same for both per-server and per-directory context with only a
5947 minimum difference (the prefix stripping in per-dir context). As a
5948 side-effect some subtle restrictions and two recently discovered problems
5949 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
5950 context and restrictions on the substitution URL on redirects.
5951 Additionally some minor source cleanups were done.

6106 Changes with Apache 1.3b2 (there is no 1.3b1)
6108 *) TestCompile was not passing $LIBS [Dean Gaudet]
6110 *) Makefile.tmpl was not using $CFLAGS in the link phase.
6113 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
6114 rudimentary memory debugger which can be used on live servers with
6115 low impact -- it sets all allocated and freed memory bytes to 0xa5.
6116 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
6117 and free() for each object. This is far more expensive and should
6118 only be used for testing with tools such as Electric Fence and
6119 Purify. See main/alloc.c for more details. [Dean Gaudet]
6121 *) Configure uses a sh trap and didn't set its exitcode properly.
6122 [Dean Gaudet] PR#1159
6124 *) Yet another vhost revamp. Add the NameVirtualHost directive which
6125 explicitly lists the ip:port pairs that are to be used for name-vhosts.
6126 From a given ip:port, regardless what the Host: header is, you can
6127 only reach the vhosts defined on that ip:port. The precedence of
6128 vhosts was reversed to match other precedences in the config --
6129 the earlier vhosts override the later vhosts. All vhost matching was
6130 moved into http_vhost.[ch]. [Dean Gaudet]
6132 *) ap_inline can be used to force inlining. GNUC __attribute__() can
6133 be used for whatever reason is appropriate (i.e. format() warnings
6134 for printf style functions). Both are enabled only with
6135 gcc >= 2.7.x (so that we have fewer support issues with older
6136 versions). [Dean Gaudet]
6138 *) Fix support for Proxy Authentication (we were testing the response
6139 status too early). [Marc Slemko]
6141 *) CoreDumpDirectory directive directs where the core file is
6142 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
6143 received. [Marc Slemko, Dean Gaudet]
6145 *) PORT: Support for Atari MINT.
6146 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
6148 *) When booting, apache will now detach itself from stdin, stdout,
6149 and stderr. stderr will not be detached until after the config
6150 files have been read so you will be able to see initial error
6151 messages. After that all errors are logged in the error_log.
6152 This makes it more convenient to start apache via rsh, ssh,
6153 or crontabs. [Dean Gaudet] PR#523
6155 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
6156 Also removed the auto-generated link to www.apache.org that was the
6157 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
6159 *) send_fb would not detect aborted connections in some situations.
6162 *) mod_include would use uninitialized data when parsing certain
6163 expressions involving && and ||. [Brian Slesinsky] PR#1139
6165 *) mod_imap should only handle GET methods. [Jay Bloodworth]
6167 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
6169 *) mod_autoindex improperly counted &escapes; as more than one
6170 character in the description. It also improperly truncated
6171 descriptions that were exactly the maximum length.
6174 *) RedirectMatch was not properly escaping the result (PR#1155). Also
6175 "RedirectMatch /advertiser/(.*) $1" is now permitted.
6178 *) mod_include now uses symbolic names to check for request success
6179 and return HTTP errors, and correctly handles all types of
6180 redirections (previously it only did temporary redirect correctly).
6181 [Ken Coar, Roy Fielding]
6183 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
6184 r->filename. Since those two are meant to be in sync with each other
6185 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]

6197 *) Fixed error in proxy_util.c when looping through multiple host IP
6198 addresses. [Lars Eilebrecht] PR#974
6200 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
6201 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
6202 bytes before writing, but it will never split a log entry across a
6203 buffer boundary. [Dean Gaudet]
6205 *) API: the short_score record has been split into two pieces, one which
6206 the parent writes on, and one which the child writes on. As part of
6207 this change the get_scoreboard_info() function was removed, and
6208 scoreboard_image was exported. This change fixes a race condition
6209 in file based scoreboard systems, and speeds up changes involving the
6210 scoreboard in earlier 1.3 development. [Dean Gaudet]
6212 *) API: New register_other_child() API (see http_main.h) which allows
6213 modules to register children with the parent for maintenance. It
6214 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
6216 *) API: New piped_log API (see http_log.h) which implements piped logs,
6217 and will use register_other_child to implement reliable piped logs
6218 when it is available. The reliable piped logs part can be disabled
6219 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
6220 logs is only available on Unix. [Dean Gaudet]
6222 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
6223 meets_conditions(). This allows conditional HTTP selection to be
6224 handled separately from the storing of the header fields, and provides
6225 the ability for CGIs to set their own ETags for conditional checking.
6226 [Ken Coar, Roy Fielding] PR#895
6228 *) Changes to mod_log_config to allow naming of format strings.
6229 Format nicknames are defined with "LogFormat fmt nickname", and can
6230 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
6233 *) New module, "mod_speling", which can help find files even when
6234 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
6236 *) API: New function child_terminate() triggers the child process to
6237 exit, while allowing the child finish what it needs to for the
6238 current request first.
6239 [Doug MacEachern, Alexei Kosut]
6241 *) Windows now defaults to using full status reports with mod_status.
6242 [Alexei Kosut] PR #1094
6244 *) *Really* disable all mod_rewrite operations if the engine is off.
6245 Some things (like RewriteMaps) were checked/performed even if they
6246 weren't supposed to be. [Ken Coar] PR #991
6248 *) Implement a new timer scheme which eliminates the need to call alarm() all
6249 the time. Instead a counter in the scoreboard for each child is used to
6250 show when the child has made forward progress. The parent samples this
6251 counter every scoreboard maintenance cycle, and issues SIGALRM if no
6252 progress has been made in the timeout period. This reduces the static
6253 request best-case syscall count to 22 from 29. This scheme is only
6254 used by systems with memory-based scoreboards. [Dean Gaudet]
6256 *) The proxy now properly handles CONNECT requests which are sent
6257 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
6259 *) A script called apachectl has been added to the support
6260 directory. This script allows you to do things such as
6261 "apachectl start" and "apachectl restart" from the command
6264 *) Modules and core routines are now put into libraries, which
6265 simplifies the link line tremendously (among other advantages).
6268 *) Some of the MD5 names defined in Apache have been renamed to have
6269 an `ap_' prefix to avoid conflicts with routines supplied by
6270 external libraries. [Ken Coar]
6272 *) Removal of mod_auth_msql.c from the distribution. There are many
6273 other options for databases today. Rather than offer one option,
6274 offer none at this time. mod_auth_msql and other SQL database
6275 authentication modules can be found at the Apache Module Registry.
6276 http://modules.apache.org/ It would be nice to offer a generic
6277 mod_auth_sql option in the near future.
6279 *) PORT: BeOS support added [Alexei Kosut]
6281 *) Configure no longer accepts the -make option, since it creates
6282 Makefile on the fly based on Makefile.tmpl and Configuration.
6284 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
6285 of forcibly killing off all its processes and exiting without
6286 cleaning up. [Alexei Kosut]
6288 *) API: A new field in the request_rec, r->mtime, has been added to
6289 avoid gratuitous parsing of date strings. It is intended to hold
6290 the last-modified date of the resource (if applicable). An
6291 update_mtime() routine has also been added to advance it if
6292 appropriate. [Roy Fielding, Ken Coar]
6294 *) SECURITY: If a htaccess file can not be read due to bad permissions,
6295 deny access to the directory with a HTTP_FORBIDDEN. The previous
6296 behavior was to ignore the htaccess file if it could not be read.
6297 This change may make some setups with unreadable htaccess files
6298 stop working. [Marc Slemko] PR#817
6300 *) Add aplog_error() providing a mechanism to define levels of
6301 verbosity to the server error logging. This addition also provides
6302 the ability to log errors using syslogd. Error logging is configurable
6303 on a per-server basis using the LogLevel directive. Conversion
6304 of log_*() in progress. [Randy Terbush]
6306 *) Further enhance aplog_error() to not log filename, line number, and
6307 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
6309 *) WIN32: Canonicalise filenames under Win32. Short filenames are
6310 converted to long ones. Backslashes are converted to forward
6311 slashes. Case is converted to lower. Parts of URLs that do not
6312 correspond to files are left completely alone. [Ben Laurie]
6314 *) PORT: 2 new OSs added to the list of ports:
6315 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
6316 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
6318 *) Add the server version (SERVER_VERSION macro) to the "server
6319 configured and running" entry in the error_log. Also build an
6320 object file at link-time that contains the current time
6321 (SERVER_BUILT global const char[]), and include that in the

6325 This fixes things such as the logging of headers sent from
6326 the proxy. [Marc Slemko] PR#659
6328 *) support/httpd_monitor is no longer distributed because the
6329 scoreboard should not be file based if at all possible. Use
6330 mod_status to see current server snapshot.
6332 *) (set_file_slot): New function, allowing auth directives to be
6333 independent of the server root, so the server documents can be
6334 moved to a different directory or machine more easily.
6335 [David J. MacKenzie]
6337 *) If no TransferLog is given explicitly, decline
6338 to log. This supports coexistence with other logging modules,
6339 such as the custom one that UUNET uses. [David J. MacKenzie]
6341 *) Check for titles in server-parsed HTML files.
6342 Ignore leading newlines and returns in titles. The old behavior
6343 of replacing a newline after <title> with a space causes the
6344 title to be misaligned in the listing. [David J. MacKenzie]
6346 *) Change mod_cern_meta to be configurable on a per-directory basis.
6347 [David J. MacKenzie]
6349 *) Add 'Include' directive to allow inclusion of configuration
6350 files within configuration files. [Randy Terbush]
6352 *) Proxy errors on connect() are logged to the error_log (nothing
6353 new); now they include the IP address and port that failed
6354 (*that's* new). [Ken Coar, Marc Slemko] PR#352
6356 *) Various architectures now define USE_MMAP_FILES which causes
6357 the server to use mmap() for static files. There are two
6358 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
6359 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
6360 number of bytes written in one cycle from a single mmap()d object,
6361 default 32768). [Dean Gaudet]
6363 *) API: Added post_read_request API phase which is run right after reading
6364 the request from a client, or right after an internal redirect. It is
6365 useful for modules setting environment variables that depend only on
6366 the headers/contents of the request. It does not run during subrequests
6367 because subrequests inherit pretty much everything from the main
6368 request. [Dean Gaudet]
6370 *) Added mod_unique_id which is used to generate a unique identifier for
6371 each hit, available in the environment variable UNIQUE_ID.
6374 *) init_modules is now called after the error logs have been opened. This
6375 allows modules to emit information messages into the error logs.
6378 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
6379 information for case where proxy module is not available. [Marc Slemko]
6381 *) PORT: Apache has need for mutexes to serialize its children around
6382 accept. In prior versions either fcntl file locking or flock file
6383 locking were used. The method is chosen by the definition of
6384 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
6385 and FLOCK for flock(). New options have been added:
6386 - SYSVSEM to use System V style semaphores
6387 - PTHREAD to use POSIX threads (appears to work on Solaris only)
6388 - USLOCK to use IRIX uslock
6389 Based on timing various techniques, the following changes were made
6391 - Linux 2.x uses flock instead of fcntl
6392 - Solaris 2.x uses pthreads
6393 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
6394 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
6395 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
6396 Martijn Koster <m.koster@pobox.com>]
6398 *) PORT: The semantics of accept/select make it very desirable to use
6399 mutexes to serialize accept when multiple Listens are in use. But
6400 in the case where only a single socket is open it is sometimes
6401 redundant to serialize accept(). Not all unixes do a good job with
6402 potentially dozens of children blocked on accept() on the same
6403 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
6404 the server will avoid serialization when listening on only one socket,
6405 and use serialization when listening on multiple sockets.
6406 [Dean Gaudet] PR#467
6408 *) Configure changes: TestLib replaced by TestCompile, which has
6409 some additional capability (such as doing a sanity check of
6410 the compiler and flags selected); the version of Solaris is now
6411 available via the #define value of SOLARIS2; IRIX n32bit libs
6412 now supported and selectable by new Configuration Rule: IRIXN32;
6413 We no longer default to -O2 optimization. [Jim Jagielski]
6415 *) Updated Configure: Configuration now uses AddModule to specify
6416 module source or binary file location, relative to src directory.
6417 Modules can be dropped into modules/extra, or in their own
6418 directory, and modules can come with a Makefile or Configure can
6419 create one. Modules can add compiler or library information to
6420 generated Makefiles. [Paul Sutton]
6422 *) Source core re-organisation: distributed modules are now in
6423 modules/standard. All other source code is in main. OS-specific
6424 code is in os/{unix,emx,win32} directories. [Paul Sutton]
6426 *) mod_browser has been removed, since it's replaced by mod_setenvif.
6429 *) Fix another long-standing bug in sub_req_lookup_file where it would
6430 happily skip past access checks on subdirectories looked up with
6431 relative paths. (It's used by mod_dir, mod_negotiation,
6432 and mod_include.) [Dean Gaudet]
6434 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
6435 N is the number of <Directory> sections, and M is the number of
6436 components in the filename of an object.
6438 To achieve this optimization the following config changes were made:
6439 - Wildcards (* and ?, not the regex forms) in <Directory>s,
6440 <Files>s, and <Location>s now treat a slash as a special
6441 character. For example "/home/*/public_html" previously would
6442 match "/home/a/andrew/public_html", now it only matches things
6443 like "/home/bob/public_html". This mimics /bin/sh behaviour.
6444 - It's possible now to use [] wildcarding in <Directory>, <Files>
6446 - Regex <Directory>s are applied after all non-regex <Directory>s.
6450 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
6451 and corrupted paths. [Dean Gaudet]
6453 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
6454 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
6455 be accessed now via backreferences $1..$9 in RewriteConds test-against
6456 strings in addition to RewriteRules subst string. Second the grouped
6457 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
6458 via backreferences %1..%9 both in following RewriteCond test-against
6459 strings and RewriteRules subst string. This provides maximum flexibility
6460 through the use of backreferences.
6461 Additionally the rewriting engine was cleaned up by putting common
6462 code to the new expand_backrefs_inbuffer() function.
6463 [Ralf S. Engelschall]
6465 *) When merging the main server's <Directory> and <Location> sections into
6466 a vhost, put the main server's first and the vhost's second. Otherwise
6467 the vhost can't override the main server. [Dean Gaudet] PR#717
6469 *) The <Directory> code would merge and re-merge the same section after
6470 a match was found, possibly causing problems with some modules.
6473 *) ip-based vhosts are stored and queried using a hashing function, which
6474 has been shown to improve performance on servers with many ip-vhosts.
6475 Some other changes had to be made to accommodate this:
6476 - the * address for vhosts now behaves like _default_
6477 - the matching process now is:
6478 - match an ip-vhost directly via hash (possibly matches main
6480 - if that fails, just pretend it matched the main server
6481 - if so far only the main server has been matched, perform
6482 name-based lookups (ServerName, ServerAlias, ServerPath)
6483 *only on name-based vhosts*
6484 - if they fail, look for _default_ vhosts
6485 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
6487 *) dbmmanage overhaul:
6488 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
6489 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
6490 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
6491 - provide better seed for rand
6492 - prompt for password as per getpass(3) (turn off echo, read from
6494 - use "newstyle" crypt based on $Config{osname} ($^O)
6495 - will not add a user if already in database, use new `update' command
6497 - added `check' command to check a users' password
6498 - added `import' command to convert existing password text-files or
6499 dbm files exported with `view'
6500 - more descriptive usage, general cleanup, 'use strict' clean, etc.
6503 *) Added psocket() which is a pool form of socket(), various places within
6504 the proxy weren't properly blocking alarms while registering the cleanup
6505 for its sockets. bclose() now uses pclose() and pclosesocket(). There
6506 was a bug where the client socket was being close()d twice due a still
6507 registered cleanup. [Dean Gaudet]
6509 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
6512 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
6513 [Jason Venner <jason@idiom.com>] PR#667
6515 *) Enable ``=""'' for RewriteCond directives to match against
6516 the empty string. This is the preferred way instead of ``^$''.
6517 [Ralf S. Engelschall]
6519 *) Fixed an infinite loop in mod_imap for references above the server root
6520 [Dean Gaudet] PR#748
6522 *) mod_proxy now has a ReceiveBufferSize directive, similar to
6523 SendBufferSize, so that the TCP window can be set appropriately
6524 for LFNs. [Phillip A. Prindeville]
6526 *) mod_browser has been replaced by the more general mod_setenvif
6527 (courtesy of Paul Sutton). BrowserMatch* directives are still
6528 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
6529 UnSetEnvIfZero directives. [Ken Coar]
6531 *) "HostnameLookups double" forces double-reverse DNS to succeed in
6532 order for remote_host to be set (for logging, or for the env var
6533 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
6536 *) mod_access overhaul:
6537 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
6538 and cidr syntax (i.e. 10.1.0.0/16). PR#762
6539 - Critical path was sped up by pre-computing a few things at config time.
6540 - The undocumented syntax "allow user-agents" was removed,
6541 the replacement is "allow from env=foobar" combined with mod_browser.
6542 - When used with hostnames it now forces a double-reverse lookup
6543 no matter what the directory settings are. This double-reverse
6544 doesn't affect any of the other routines that use the remote
6545 hostname. In particular it's still passed to CGIs and the log
6546 without the double-reverse check. Related PR#860.
6549 *) When a large bwrite() occurs (larger than the internal buffer size),
6550 while there is already something in the buffer, apache will combine
6551 the large write and the buffer into a single writev(). (This is
6552 in anticipation of using mmap() for reading files.)
6555 *) In obscure cases where a partial socket write occurred while chunking,
6556 Apache would omit the chunk header/footer on the next block. Cleaned
6557 up other bugs/inconsistencies in error conditions in buff.c. Fixed
6558 a bug where a long pause in DNS lookups could cause the last packet
6559 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
6561 *) API: Added child_exit function to module structure. This is called
6562 once per "heavy-weight process" just before a server child exit()'s
6563 e.g. when max_requests_per_child is reached, etc.
6564 [Doug MacEachern, Dean Gaudet]
6566 *) mod_include cleanup showed that handle_else was being used to handle
6567 endif. It didn't cause problems, but it was cleaned up too.
6570 *) mod_cern_meta would attempt to find meta files for the directory itself
6571 in some cases, but not in others. It now avoids it in all cases.
6574 *) mod_mime_magic would core dump if there was a decompression error.
6575 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
6577 *) PORT: some variants of DGUX require -lsocket -lnsl
6578 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
6580 *) mod_autoindex now allows sorting of FancyIndexed directory listings
6581 by the various fields (name, size, et cetera), either in ascending
6582 or descending order. Just click on the column header. [Ken Coar]
6584 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
6585 CPUs like the Alpha. Apache still stores ints in pointers, but that's
6586 the relatively safe direction. [Dean Gaudet] PR#344
6588 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
6589 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
6591 *) child_main avoids an unneeded call to select() when there is only one
6592 listening socket. [Dean Gaudet]
6594 *) In the event that the server is starved for idle servers it will
6595 spawn 1, then 2, then 4, ..., then 32 servers each second,
6596 doubling each second. It'll also give a warning in the errorlog
6597 since the most common reason for this is a poor StartServers
6598 setting. The define MAX_SPAWN_RATE can be used to raise/lower
6599 the maximum. [Dean Gaudet]
6601 *) Apache now provides an effectively unbuffered connection for
6602 CGI scripts. This means that data will be sent to the client
6603 as soon as the CGI pauses or stops output; previously, Apache would
6604 buffer the output up to a fixed buffer size before sending, which
6605 could result in the user viewing an empty page until the CGI finished
6606 or output a complete buffer. It is no longer necessary to use an
6607 "nph-" CGI to get unbuffered output. Given that most CGIs are written
6608 in a language that by default does buffering (e.g. perl) this
6609 shouldn't have a detrimental effect on performance.
6611 "nph-" CGIs, which formerly provided a direct socket to the client
6612 without any server post-processing, were not fully compatible with
6613 HTTP/1.1 or SSL support. As such they would have had to implement
6614 the transport details, such as encryption or chunking, in order
6615 to work properly in certain situations. Now, the only difference
6616 between nph and non-nph scripts is "non-parsed headers".
6617 [Dean Gaudet, Sameer Parekh, Roy Fielding]
6619 *) If a BUFF is switched from buffered to unbuffered reading the first
6620 bread() will return whatever remained in the buffer prior to the
6621 switch. [Dean Gaudet]
6623 Changes with Apache 1.3a1
6625 *) Added another Configure helper script: TestLib. It determines
6626 if a specified library exists. [Jim Jagielski]
6628 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
6629 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
6632 *) PORT: Some architectures use size_t for various lengths in network
6633 functions such as accept(), and getsockname(). The definition
6634 NET_SIZE_T is used to control this. [Dean Gaudet]
6636 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
6637 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
6638 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
6640 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
6641 [Igor N Kovalenko <infoh@mail.wplus.net>]
6643 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
6644 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
6645 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
6646 [Dean Gaudet] related PR#875
6648 *) API: Correct child_init() slot declaration from int to void, to
6649 match the init() declaration. Update mod_example to use the new
6652 *) added transport handle slot (t_handle) to the BUFF structure
6655 *) get_client_block() returns wrong length if policy is
6656 REQUEST_CHUNKED_DECHUNK.

6659 *) Support the image map format of FrontPage. For example:

6663 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
6664 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
6666 *) AddModuleInfo directive for mod_info which allows you to annotate
6667 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
6669 *) Added NoProxy directive to avoid using ProxyRemote for selected
6670 addresses. Added ProxyDomain directive to cause unqualified
6671 names to be qualified by redirection.
6672 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
6674 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
6675 header to the remote host in the proxy. [Sameer Parekh and
6678 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
6679 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
6680 URLs, fixed rewritelog(), fixed forced response code handling on
6681 redirects from within .htaccess files, disabled pipe locking under
6682 braindead SunOS 4.1.x, allow env variables to be set even on rules with
6683 no substitution, bugfixed situations where HostnameLookups is off, made
6684 mod_rewrite more thread-safe for NT port and fixed problem when creating
6685 an empty query string via "xxx?".
6686 This update also removes the copyright of Ralf S. Engelschall,
6687 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
6688 exclusively copyrighted by the Apache Group now. This happened because
6689 the author now has gifted mod_rewrite exclusively to the Apache Group and
6690 no longer maintains an external version.
6691 [Ralf S. Engelschall]
6693 *) API: Added child_init function to module structure. This is called
6694 once per "heavy-weight process" before any requests are handled.
6695 See http_config.h for more details. [Dean Gaudet]
6697 *) Anonymous_LogEmail was logging on each subrequest.
6698 [Dean Gaudet] PR#421, 868
6700 *) API: Added is_initial_req() which tests if the request being
6701 processed is the initial request, or a subrequest.
6704 *) Extended SSI (mod_include) now handles additional relops for
6705 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
6707 *) Configure fixed to correctly propagate user-selected options and
6708 settings (such as CC and OPTIM) to Makefiles other than
6709 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
6711 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
6712 directory indices to start with the contents of the HeaderName file
6713 if there is one. If there isn't one, the behaviour is unchanged.
6714 [Ken Coar, Roy Fielding, Andrey A. Chernov]
6716 *) WIN32: Modules can now be dynamically loaded DLLs using the
6717 LoadModule/LoadFile directives. Note that module DLLs must be
6718 compiled with the multithreaded DLL version of the runtime library.
6719 [Alexei Kosut and Ben Laurie]
6721 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
6722 This allows the admin to completely remove automatic indexing
6723 from the server, while still supporting the basic functions of
6724 trailing-slash redirects and DirectoryIndex files. Note that if
6725 you're carrying over an old Configuration file and you use directory
6726 indexing then you'll want to add:
6728 Module autoindex_module mod_autoindex.o
6730 before mod_dir in your Configuration. [Dean Gaudet]
6732 *) popendir/pclosedir created to properly protect directory scanning.
6733 [Dean Gaudet] PR#525
6735 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
6736 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
6737 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
6740 *) The AccessFileName directive can now take more than one filename.
6741 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
6743 *) The new mod_mime_magic can be used to "magically" determine the type
6744 of a file if the extension is unknown. Based on the unix file(1)
6745 command. [Ian Kluft <ikluft@cisco.com>]
6747 *) We now determine and display the time spent processing a
6748 request if desired. [Jim Jagielski]
6750 *) mod_status: PID field of "dead" child slots no longer displays
6751 main httpd process's PID. [Jim Jagielski]
6753 *) Makefile.nt added - to build all the bits from the command line:
6754 nmake -f Makefile.nt
6755 Doesn't yet work properly. [Ben Laurie]
6757 *) Default text of 404 error is now "Not Found" rather than the
6758 potentially misleading "File Not Found". [Ken Coar]
6760 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
6761 for the net if we require people that actually need this data to
6762 enable it. [Linus Torvalds]
6764 *) directory_walk() is an expensive function, keep a little more state to
6765 avoid needless string counting. Add two new functions make_dirstr_parent
6766 and make_dirstr_prefix which replace all existing uses of make_dirstr.
6767 The new functions are a little less general than make_dirstr, but
6768 work more efficiently (less memory, less string counting).
6771 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
6772 to LDFLAGS) to avoid complications with lex rules in make files.
6773 [Dean Gaudet] PR#372
6775 *) run_method optimized to avoid needless scanning over NULLs in the
6776 module list. [Dean Gaudet]
6778 *) Revamp of (unix) scoreboard management code such that it avoids
6779 unnecessary traversals of the scoreboard on each hit. This is
6780 particularly important for high volume sites with a large
6781 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
6782 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
6783 httpd.h. [Dean Gaudet]
6785 *) In configurations using multiple Listen statements it was possible for
6786 busy sockets to starve other sockets of service. [Dean Gaudet]
6788 *) Added hook so standalone_main can be replaced at compile time
6789 (define STANDALONE_MAIN)
6792 *) Lowest-level read/write functions in buff.c will be replaced with
6793 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
6794 compile time. The default sfio discipline will behave as apache
6795 would without sfio compiled in.
6798 *) Enhance UserDir directive (mod_userdir) to accept a list of
6799 usernames for the 'disable' keyword, and add 'enable user...' to
6800 selectively *en*able userdirs if they're globally disabled.
6803 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
6804 will work with Netscape dbm files. (dbmmanage will probably not
6805 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
6807 *) Add a ListenBacklog directive to control the backlog parameter
6808 passed to listen(). Also change the default to 511 from 512.
6811 *) API: A new handler response DONE which informs apache that the
6812 request has been handled and it can finish off quickly, similar to
6813 how it handles errors. [Rob Hartill]
6815 *) Turn off chunked encoding after sending terminating chunk/footer
6816 so that we can't do it twice by accident. [Roy Fielding]
6818 *) mod_expire also issues Cache-Control: max-age headers.
6821 *) API: Added kill_only_once option for free_proc_chain so that it won't
6822 aggressively try to kill off specific children. For fastcgi.
6823 [Stanley Gambarin <gambarin@OpenMarket.com>]
6825 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
6827 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
6828 When used together, these cause mod_dir to emit HEIGHT and WIDTH
6829 attributes in the FancyIndexing IMG tags. [Ken Coar]
6831 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
6833 *) PORT: Added Windows NT support
6834 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
6836 Changes with Apache 1.2.6
6838 *) mod_include when using XBitHack Full would send ETags in addition to
6839 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
6840 [Dean Gaudet] PR#1133
6842 *) SECURITY: When a client connects to a particular port/addr, and
6843 gives a Host: header ensure that the virtual host requested can
6844 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
6846 *) Support virtual hosts with wildcard port and/or multiple ports
6847 properly. [Ed Korthof <ed@organic.com>]
6849 *) Fixed some case-sensitivity issues according to RFC2068.
6852 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
6853 and mod_include.c. [Dean Gaudet]
6855 *) Variable 'cwd' was being used pointlessly before being set.
6858 *) SIGURG doesn't exist on all platforms.
6859 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
6861 *) When an error occurs during a POST, or other operation with a
6862 request body, the body has to be read from the net before allowing
6863 a keepalive session to continue. [Roy Fielding] PR#1399
6865 *) When an error occurs in fcntl() locking suggest the user look up
6866 the docs for LockFile. [Dean Gaudet]
6868 *) table_set() and table_unset() did not deal correctly with
6869 multiple occurrences of the same key. [Stephen Scheck
6870 <sscheck@infonex.net>, Ben Laurie] PR#1604
6872 *) send_fd_length() did not calculate total_bytes_sent properly in error
6873 cases. [Ben Reser <breser@regnow.com>] PR#1366
6875 *) r->connection->user was allocated in the wrong pool causing corruption
6876 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
6878 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
6879 Also removed the auto-generated link to www.apache.org that was the
6880 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
6882 *) Multiple "close" tokens may have been set in the "Connection"
6883 header, not an error, but a waste.
6884 [Ronald.Tschalaer@psi.ch] PR#1683
6886 *) "basic" and "digest" auth tokens should be tested case-insensitive.
6887 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
6889 *) It appears the "257th byte" bug (see
6890 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
6891 at the 256th byte as well. Fixed. [Dean Gaudet]
6893 *) mod_rewrite would not handle %3f properly in some situations.
6896 *) Apache could generate improperly chunked HTTP/1.1 responses when
6897 the bputc() or rputc() functions were used by modules (such as
6898 mod_include). [Dean Gaudet]
6900 *) #ifdef wrap a few #defines in httpd.h to make life easier on
6901 some ports. [Ralf Engelschall]
6903 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
6905 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
6907 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
6909 Changes with Apache 1.2.5
6911 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
6912 only an issue on systems without a MAXDNAME define or where
6913 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
6915 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
6918 *) Fix core dump in the ftp proxy when reading incorrectly formatted
6919 directory listings. [Marc Slemko]
6921 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
6924 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
6925 is used to read various types of files such as htaccess and
6926 htpasswd files. [Marc Slemko]
6928 *) SECURITY: Ensure that the buffer returned by ht_time is always
6929 properly null terminated. [Marc Slemko]
6931 *) SECURITY: General mod_include cleanup, including fixing several
6932 possible buffer overflows and a possible infinite loop. This cleanup
6933 was done against 1.3 code and then backported to 1.2, the result
6934 is a large difference (due to indentation cleanup in 1.3 code).
6935 Users interested in seeing a smaller set of relevant differences
6936 should consider comparing against src/modules/standard/mod_include.c
6937 from the 1.3b3 release. Non-indentation changes to mod_include
6938 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
6940 *) SECURITY: Numerous changes to mod_imap in a general cleanup
6941 including fixing a possible buffer overflow. This cleanup also
6942 was done with 1.3 code as a basis, see the the previous note
6943 about mod_include. [Dean Gaudet]
6945 *) SECURITY: If a htaccess file can not be read due to bad
6946 permissions, deny access to the directory with a HTTP_FORBIDDEN.
6947 The previous behavior was to ignore the htaccess file if it could not
6948 be read. This change may make some setups with unreadable
6949 htaccess files stop working. PR#817 [Marc Slemko]
6951 *) SECURITY: no2slash() was O(n^2) in the length of the input.
6952 Make it O(n). This inefficiency could be used to mount a denial
6953 of service attack against the Apache server. Thanks to
6954 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting

6961 [Jay Bloodworth <jay@pathways.sde.state.sc.us>]
6963 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
6965 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
6966 r->filename. Since those two are meant to be in sync with each other
6967 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
6969 *) mod_include did not properly handle all possible redirects from sub-
6970 requests. [Ken Coar]
6972 *) Inetd mode (which is buggy) uses timeouts without having setup the
6973 jmpbuffer. [Dean Gaudet] PR#1064

6976 reporting a select error over and over.
6977 [Rick Franchuk <rickf@transpect.net>] PR#1107
6979 Changes with Apache 1.2.4
6981 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
6982 always making requests with the full-URI instead of just the URI path.
6983 [Marc Slemko, Roy Fielding]
6985 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
6986 on this platform. [Marc Slemko]
6988 Changes with Apache 1.2.3
6990 *) The request to a remote proxy was mangled if it was generated as the
6991 result of a ProxyPass directive. URL schemes other than http:// were not
6992 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
6993 PR#812 [Lars Eilebrecht]
6995 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
6996 information for case where proxy module is not available. [Marc Slemko]
6998 *) Force proxy to always respond as HTTP/1.0, which it was failing to
6999 do for errors and cached responses. [Roy Fielding]
7001 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
7003 Changes with Apache 1.2.2 [not released]
7005 *) Fixed another long-standing bug in sub_req_lookup_file where it would
7006 happily skip past access checks on subdirectories looked up with relative
7007 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
7010 *) Add lockfile name to error message printed out when
7011 USE_FLOCK_SERIALIZED_ACCEPT is defined.
7014 *) Enhanced the chunking and error handling inside the buffer functions.
7015 [Dean Gaudet, Roy Fielding]
7017 *) When merging the main server's <Directory> and <Location> sections into
7018 a vhost, put the main server's first and the vhost's second. Otherwise
7019 the vhost can't override the main server. [Dean Gaudet] PR#717
7021 *) The <Directory> code would merge and re-merge the same section after
7022 a match was found, possibly causing problems with some modules.
7025 *) Fixed an infinite loop in mod_imap for references above the server root.
7026 [Dean Gaudet] PR#748
7028 *) mod_include cleanup showed that handle_else was being used to handle
7029 endif. It didn't cause problems, but it was cleaned up too.
7032 *) Last official synchronization of mod_rewrite with author version (because
7033 mod_rewrite is now directly developed by the author at the Apache Group):
7034 o added diff between mod_rewrite 3.0.6+ and 3.0.9
7035 minus WIN32/NT stuff, but plus copyright removement.
7037 - workaround for detecting infinite rewriting loops
7038 - fixed setting of env vars when "-" is used as subst string
7039 - fixed forced response code on redirects (PR#777)
7040 - fixed cases where r->args is ""
7041 - kludge to disable locking on pipes under braindead SunOS
7042 - fix for rewritelog in cases where remote hostname is unknown
7043 - fixed totally damaged request_rec walk-back loop
7044 o remove static from local data and add static to global ones.
7045 o replaced ugly proxy finding stuff by simple
7046 find_linked_module("mod_proxy") call.
7047 o added missing negation char on rewritelog()
7048 o fixed a few comment typos
7049 [Ralf S. Engelschall]
7051 *) Anonymous_LogEmail was logging on each subrequest.
7052 [Dean Gaudet] PR#421, PR#868
7054 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7055 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7056 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
7057 Additionally mod_browser now triggers during translate_name to workaround
7058 a deficiency in the header_parse phase.

7068 *) The proxy didn't treat the "Host:" keyword of the host header as case-
7069 insensitive. The proxy would corrupt the first line of a response from
7070 an HTTP/0.9 server. [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#813,814
7072 *) mod_include would log some bogus values occasionally.

7075 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
7076 under Solaris 2.x (up through 2.5.1). It has been fixed.
7077 [Dean Gaudet] PR#832
7079 *) API: In HTTP/1.1, whether or not a request message contains a body
7080 is independent of the request method and based solely on the presence
7081 of a Content-Length or Transfer-Encoding. Therefore, our default
7082 handlers need to be prepared to read a body even if they don't know
7083 what to do with it; otherwise, the body would be mistaken for the
7084 next request on a persistent connection. discard_request_body()
7085 has been added to take care of that. [Roy Fielding] PR#378
7087 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
7088 release version number, such that it always increases along the
7089 same lines as our source code branching. [Roy Fielding]
7091 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
7093 Changes with Apache 1.2.1
7095 *) SECURITY: Don't serve file system objects unless they are plain files,
7096 symlinks, or directories. This prevents local users from using pipes
7097 or named sockets to invoke programs for an extremely crude form of

7101 could contain "../" allowing a local user to "publish" any file on
7102 the system. No slashes are allowed now. [Dean Gaudet]
7104 *) SECURITY: It was possible to violate the symlink Options using mod_dir
7105 (headers, readmes, titles), mod_negotiation (type maps), or
7106 mod_cern_meta (meta files). [Dean Gaudet]
7108 *) SECURITY: Apache will refuse to run as "User root" unless
7109 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
7111 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
7112 if it contained a .htaccess disallowing symlinks. This is contrary
7113 to the rule that symlink permissions are tested with the symlink
7114 options of the parent directory. [Dean Gaudet] PR#353
7116 *) CONFIG: The LockFile directive can be used to place the serializing
7117 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
7118 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
7121 *) Request processing now retains state of whether or not the request
7122 body has been read, so that internal redirects and subrequests will
7123 not try to read it twice (and block). [Roy Fielding]
7125 *) Add a placeholder in modules/Makefile to avoid errors with certain
7126 makes. [Marc Slemko]
7128 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.
7129 [Dean Gaudet] PR#644
7131 *) mod_include was not properly changing the current directory.
7132 [Marc Slemko] PR#742
7134 *) Attempt to work around problems with third party libraries that do not
7135 handle high numbered descriptors (examples include bind, and
7136 solaris libc). On all systems apache attempts to keep all permanent
7137 descriptors above 15 (called the low slack line). Solaris users
7138 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
7139 which keeps all non-FILE * descriptors above 255. On all systems
7140 this should make supporting large numbers of vhosts with many open
7141 log files more feasible. If this causes trouble please report it,
7142 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
7143 [Dean Gaudet] various PRs
7145 *) Related to the last entry, network sockets are now opened before
7146 log files are opened. The only known case where this can cause
7147 problems is under Solaris with many virtualhosts and many Listen
7148 directives. But using -DHIGH_SLACK_LINE=256 described above will
7149 work around this problem. [Dean Gaudet]

7204 reading from one buffer and writing to another, at least until it has
7205 a custom timeout handler. [Roy Fielding and Petr Lampa]

7221 [Chuck Murcko] PR#614
7223 *) If multiple requests on a single connection are used to retrieve

7240 *) If a soft_timeout occurs after keepalive is set, then the main child
7241 loop would try to read another request even though the connection
7242 has been aborted. [Roy Fielding]
7244 *) Configure changes: Allow for whitespace at the start of a
7245 Module declaration. Also, be more understanding about the
7246 CC=/OPTIM= format in Configuration. Finally, fix compiler
7247 flags if using HP-UX's cc compiler. [Jim Jagielski]
7249 *) Subrequests and internal redirects now inherit the_request from the
7250 original request-line. [Roy Fielding]
7252 *) Test for error conditions before creating output header fields, since
7253 we don't want the error message to include those fields. Likewise,
7254 reset the content_language(s) and content_encoding of the response
7255 before generating or redirecting to an error message, since the new
7256 message will have its own Content-* definitions. [Dean Gaudet]

7259 and 304 responses) and err_headers_out (headers sent with all responses).
7260 Avoid the overhead of copying tables if err_headers_out is empty
7261 (the usual case). [Roy Fielding]

7264 not properly checking both the value configured by the DefaultType
7265 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
7266 of DEFAULT_TYPE to match the documented default (text/plain).

7272 *) Properly initialize the flock structures used by the mutex locking
7273 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
7276 *) The method for determining PATH_INFO has been restored to the pre-1.2b
7277 (and NCSA httpd) definition wherein it was the extra path info beyond
7278 the CGI script filename. The environment variable FILEPATH_INFO has
7279 been removed, and instead we supply the original REQUEST_URI to any
7280 script that wants to be Apache-specific and needs the real URI path.
7281 This solves a problem with existing scripts that use extra path info
7282 in the ScriptAlias directive to pass options to the CGI script.
7285 *) The _default_ change in 1.2b10 will change the behaviour on configs
7286 that use multiple Listen statements for listening on multiple ports.
7287 But that change is necessary to make _default_ consistent with other
7288 forms of <VirtualHost>. It requires such configs to be modified
7289 to use <VirtualHost _default_:*>. The documentation has been
7290 updated. [Dean Gaudet] PR#530
7292 *) If an ErrorDocument CGI script is used to respond to an error
7293 generated by another CGI script which has already read the message
7294 body of the request, the server would block trying to read the
7295 message body again. [Rob Hartill]

7373 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
7374 parsing of headers. If the terminating empty-line CRLF occurs starting
7375 at the 256th or 257th byte of output, then Navigator will think a normal
7376 image is invalid. We are guessing that this is because their initial
7377 read of a new request uses a 256 byte buffer. We check the bytes written
7378 so far and, if we are about to tickle the bug, we instead insert a
7379 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232

7406 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
7407 [Dean Gaudet] PR#336, PR#340
7409 *) Redirect did not preserve ?query_strings when present in the client's
7410 request. [Dean Gaudet]
7412 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
7414 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
7416 *) Add UnixWare compile/install instructions. [Chuck Murcko]
7418 *) Add mod_example (illustration of API techniques). [Ken Coar]
7420 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
7422 *) Improve handling of directories when filenames have spaces in them.
7425 *) For hosts with multiple IP addresses, try all additional addresses if
7426 necessary to get a connect. Fail only if hostent address list is
7427 exhausted. [Chuck Murcko]
7429 *) More signed/unsigned port fixes. [Dean Gaudet]
7431 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
7434 Changes with Apache 1.2b8
7436 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
7437 to it. [Marc Slemko]
7439 *) The addition of <Location> and <File> directives made the
7440 sub_req_lookup_simple() function bogus, so we now handle
7441 the special cases directly. [Dean Gaudet]
7443 *) We now try to log where the server is dumping core when a fatal
7444 signal is received. [Ken Coar]
7446 *) Improved lingering_close by adding a special timeout, removing the
7447 spurious log messages, removing the nonblocking settings (they
7448 are not needed with the better timeout), and adding commentary
7449 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
7450 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
7452 *) Send error messages about setsockopt failures to the server error
7453 log instead of stderr. [Roy Fielding]
7455 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
7457 *) Stopgap solution for CGI 3-second delay with server-side includes: if
7458 processing a subrequest, allocate memory from r->main->pool instead
7459 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
7460 in the middle of an SSI request. [Dean Gaudet] PR #122
7462 *) Fixed status of response when POST is received for a nonexistent URL
7463 (was sending 405, now 404) and when any method is sent with a
7464 full-URI that doesn't match the server and the server is not acting
7465 as a proxy (was sending 501, now 403). [Roy Fielding]
7467 *) Host port changed to unsigned short. [Ken Coar] PR #276
7469 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
7471 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
7473 *) Report extra info from errno with many errors that cause httpd to exit.
7474 spawn_child, popenf, and pclosef now have valid errno returns in the
7475 event of an error. Correct problems where errno was stomped on
7476 before being reported. [Dean Gaudet]
7478 *) In the proxy, if the cache filesystem was full, garbage_coll() was
7479 never called, and thus the filesystem would remain full indefinitely.
7480 We now also remove incomplete cache files left if the origin server
7481 didn't send a Content-Length header and either the client has aborted
7482 transfer or bwrite() to client has failed. [Petr Lampa]
7484 *) Fixed the handling of module and script-added header fields.
7485 Improved the interface for sending header fields and reduced
7486 the duplication of code between sending okay responses and errors.
7487 We now always send both headers_out and err_headers_out, and
7488 ensure that the server-reserved fields are not being overridden,
7489 while not overriding those that are not reserved. [Roy Fielding]
7491 *) Moved transparent content negotiation fields to err_headers_out
7492 to reflect above changes. [Petr Lampa]
7494 *) Fixed the determination of whether or not we should make the
7495 connection persistent for all of the cases where some other part
7496 of the server has already indicated that we should not. Also
7497 improved the ordering of the test so that chunked encoding will
7498 be set whenever it is desired instead of only when KeepAlive
7499 is enabled. Added persistent connection capability for most error
7500 responses (those that do not indicate a bad input stream) when
7501 accessed by an HTTP/1.1 client. [Roy Fielding]
7503 *) Added missing timeouts for sending header fields, error responses,
7504 and the last chunk of chunked encoding, each of which could have
7505 resulted in a process being stuck in write forever. Using soft_timeout
7506 requires that the sender check for an aborted connection rather than
7507 continuing after an EINTR. Timeouts that used to be initiated before
7508 send_http_header (and never killed) are now initiated only within or
7509 around the routines that actually do the sending, and not allowed to
7510 propagate above the caller. [Roy Fielding]
7512 *) mod_auth_anon required an @ or a . in the email address, not both.
7515 *) per_dir_defaults weren't set correctly until directory_walk for
7516 name-based vhosts. This fixes an obscure bug with the wrong config
7517 info being used for vhosts that share the same ip as the server.
7520 *) Improved generation of modules/Makefile to be more generic for
7521 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
7523 *) Generate makefile dependency for Configuration based on the actual
7524 name given when running the Configure process. [Dean Gaudet]
7526 *) Fixed problem with vhost error log not being set prior to
7527 initializing virtual hosts. [Dean Gaudet]
7529 *) Fixed infinite loop when a trailing slash is included after a type map
7530 file URL (extra path info). [Petr Lampa]
7532 *) Fixed server status updating of per-connection counters. [Roy Fielding]
7534 *) Add documentation for DNS issues (reliability and security), and try
7535 to explain the virtual host matching process. [Dean Gaudet]
7537 *) Try to continue gracefully by disabling the vhost if a DNS lookup
7538 fails while parsing the configuration file. [Dean Gaudet]
7540 *) Improved calls to setsockopt. [Roy Fielding]
7542 *) Negotiation changes: Don't output empty content-type in variant list;
7543 Output charset in variant list; Return sooner from handle_multi() if
7544 no variants found; Add handling of '*' wildcard in Accept-Charset.
7545 [Petr Lampa and Paul Sutton]
7547 *) Fixed overlaying of request/sub-request notes and headers in
7548 mod_negotiation. [Dean Gaudet]
7550 *) If two variants' charset quality are equal and one is the default
7551 charset (iso-8859-1), then prefer the variant that was specifically
7552 listed in Accept-Charset instead of the default. [Petr Lampa]
7554 *) Memory allocation problem in push_array() -- it would corrupt memory
7555 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
7557 *) invoke_handler() doesn't handle mime arguments in content-type
7560 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
7563 *) Fixed problem with ErrorDocument not working for virtual hosts
7564 due to one of the performance changes in 1.2b7. [Dean Gaudet]
7566 *) Log an error message if we get a request header that is too long,
7567 since it may indicate a buffer overflow attack. [Marc Slemko]
7569 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
7570 not reject URLs without a double-slash, as per RFC2068 section 3.2.
7571 [Ken Coar] PR #146, #187
7573 *) Added table entry placeholder for new header_parser callback
7574 in all of the distributed modules. [Ken Coar] PR #191
7576 *) Allow for cgi files without the .EXE extension on them under OS/2.
7577 [Garey Smiley] PR #59
7579 *) Fixed error message when resource is not found and URL contains
7580 path info. [Petr Lampa and Dean Gaudet] PR #40
7582 *) Fixed user and server confusion over what should be a virtual host
7583 and what is the main server, resulting in access to something
7584 other than the name defined in the virtualhost directive (but
7585 with the same IP address) failing. [Dean Gaudet]
7587 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
7588 AIX; improves the redirection stuff to enable the users to generally
7589 redirect to http, https, gopher and ftp; added TIME variable for
7590 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
7591 special patterns >STRING, <STRING and =STRING to RewriteCond, which
7592 can be used in conjunction with %{TIME} or other variables to create
7593 time-dependent rewriting rules. [Ralf S. Engelschall]
7595 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
7596 Module authors may need to adjust their code for proper cleanup to take
7597 place (that is, call note_cleanups_for_fd()). This change fixes problems
7598 with file descriptors being erroneously closed when the proxy module was
7599 in use. [Ben Laurie]
7601 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
7602 initgroups() to hose the group information needed for later
7603 comparisons. [Randy Terbush]
7605 *) Remove unnecessary call to va_end() in create_argv() which
7606 caused a SEGV on some systems.
7608 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
7611 *) Clear memory allocated for listeners. [Randy Terbush]
7613 *) Improved handling of IP address as a virtualhost address and
7614 introduced "_default_" as a synonym for the default vhost config.
7615 [Dean Gaudet] PR #212
7617 Changes with Apache 1.2b7
7619 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
7621 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
7623 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
7624 - replace protocol response numbers with symbols
7625 - save variant-list into main request notes
7626 - free allocated memory from subrequests
7627 - merge notes, headers_out and err_headers_out
7629 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
7630 "HTTP/#.# ###*" to be more lenient about what we accept.
7633 *) more proxy FTP bug fixes:
7634 - Changed send_dir() to remove user/passwd from displayed URL.
7635 - Changed login error messages to be more descriptive.
7636 - remove setting of SO_DEBUG socket option
7637 - Make ftp_getrc() more lenient about multiline responses,
7638 specifically, 230 responses which don't have continuation 230-
7639 on each line). These seem to be all NT FTP servers, and while
7640 perhaps questionable, they appear to be legal by RFC 959.
7641 - Add missing kill_timeout() after transfer to user completes.
7644 *) Fixed problem where a busy server could hang when restarting
7645 after being sent a SIGHUP due to child processes not exiting.
7648 *) Modify mod_include escaping so a '\' only signifies an escaped
7649 character if the next character is one that needs
7650 escaping. [Ben Laurie]
7652 *) Eliminated possible infinite loop in mod_imap when relative URLs are
7653 used with a 'base' directive that does not have a '/' in it.
7654 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
7656 *) Reduced the default timeout from 1200 seconds to 300, and the
7657 one in the sample configfile from 400 to 300. [Marc Slemko]
7659 *) Stop vbprintf from crashing if given a NULL string pointer;
7660 print (null) instead. [Ken Coar]
7662 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
7663 [Marc Slemko and Roy Fielding]
7665 *) Fixed problem with mod_cgi-generated internal redirects trying to
7666 read the request message-body twice. [Archie Cobbs and Roy Fielding]
7668 *) Reduced timeout on lingering close, removed possibility of a blocked
7669 read causing the child to hang, and stopped logging of errors if
7670 the socket is not connected (reset by client). [Roy Fielding]
7672 *) Rearranged main child loop to remove duplication of code in
7673 select/accept and keep-alive requests, fixed several bugs regarding
7674 checking scoreboard_image for exit indication and failure to
7675 account for all success conditions and trap all error conditions,
7676 prevented multiple flushes before closing the socket; close the entire
7677 socket buffer instead of just one descriptor, prevent logging of
7678 EPROTO and ECONNABORTED on platforms where supported, and generally
7679 improved readability. [Roy Fielding]
7681 *) Extensive performance improvements. Cleaned up inefficient use of
7682 auto initializers, multiple is_matchexp calls on a static string,
7683 and excessive merging of response_code_strings. [Dean Gaudet]
7685 *) Added double-buffering to mod_include to improve performance on
7686 server-side includes. [Marc Slemko]
7688 *) Several fixes for suexec wrapper. [Randy Terbush]
7689 - Make wrapper work for files on NFS filesystem.
7690 - Fix portability problem of MAXPATHLEN.
7691 - Fix array overrun problem in clean_env().
7692 - Fix allocation of PATH environment variable
7694 *) Removed extraneous blank line is description of mod_status chars.
7697 *) Logging of errors from the call_exec routine simply went nowhere,
7698 since the logfile fd has been closed, so now we send them to stderr.
7699 [Harald T. Alvestrand]
7701 *) Fixed core dump when DocumentRoot is a CGI.
7702 [Ben Laurie, reported by geddis@tesserae.com]
7704 *) Fixed potential file descriptor leak in mod_asis; updated it and
7705 http_core to use pfopen/pfclose instead of fopen/fclose.
7706 [Randy Terbush and Roy Fielding]
7708 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
7709 as the DEC Alpha which is 64-bit but uses 32-bit ints.
7710 [Dean Gaudet and Ken Coar]
7712 *) Return a 302 response code to the client when sending a redirect
7713 due to a missing trailing '/' on a directory instead of a 301; now
7714 it is cacheable. [Markus Gyger]
7716 *) Fix condition where, if a bad directive occurs in .htaccess, and
7717 sub_request() goes first to this directory, then log_reason() will
7718 SIGSEGV because it doesn't have initialized r->per_dir_config.
7719 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
7721 *) Fix handling of lang_index in is_variant_better(). This was
7722 causing problems which resulted in the server sending the
7723 wrong language document in some cases. [Petr Lampa]
7725 *) Remove free() from clean_env() in suexec wrapper. This was nuking
7726 the clean environment on some systems.
7728 *) Tweak byteserving code (e.g. serving PDF files) to work around
7729 bugs in Netscape Navigator and Microsoft Internet Explorer.
7730 Emit Content-Length header when sending multipart/byteranges.
7733 *) Port to HI-UX/WE2. [Nick Maclaren]
7735 *) Port to HP MPE operating system for HP 3000 machines
7736 [Mark Bixby <markb@cccd.edu>]
7738 *) Fixed bug which caused a segmentation fault if only one argument
7739 given to RLimit* directives. [Ed Korthof]
7741 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
7743 *) Improved buffered output to the client by delaying the flush decision
7744 until the BUFF code is actually about to read the next request.
7745 This fixes a problem introduced in 1.2b5 with clients that send
7746 an extra CRLF after a POST request. Also improved chunked output
7747 performance by combining writes using writev() and removing as
7748 many bflush() calls as possible. NOTE: Platforms without writev()
7749 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
7750 or Configure, unless we have already done so. [Dean Gaudet]
7752 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
7754 *) Fixed mod_info output corruption bug introduced by buffer overflow
7755 fixes. [Dean Gaudet]
7757 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
7758 for the special case of a 304 response. [Paul Sutton]
7760 *) Improved handling of TRACE method by bypassing normal method handling
7761 and header parsing routines; fixed Allow response to always allow TRACE.
7764 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
7766 *) Cleaned-up some of the generated HTML. [Ken Coar]
7768 Changes with Apache 1.2b6
7770 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
7772 *) Fix typo introduced in fix for potential infinite loop around
7773 accept() in child_main(). This change caused the rev to 1.2b6.
7774 1.2b5 was never a public beta.
7776 Changes with Apache 1.2b5
7778 *) Change KeepAlive semantics (On|Off instead of a number), add
7779 MaxKeepAliveRequests directive. [Alexei Kosut]
7781 *) Various NeXT compilation patches, as well as a change in
7782 regex/regcomp.c since that file also used a NEXT define.
7785 *) Allow * to terminate the end of a directory match in mod_dir.
7786 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
7788 *) Don't call can_exec() if suexec_enabled. Calling this requires
7789 scripts executed by the suexec wrapper to be world executable, which
7790 defeats one of the advantages of running the wrapper. [Randy Terbush]
7792 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
7795 *) Migration from sprintf() to snprintf() to avoid buffer
7796 overflows. [Marc Slemko]
7798 *) Provide portable snprintf() implementation (ap_snprintf)
7799 as well as *cvt family. [Jim Jagielski]
7801 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
7804 *) Remove mod_fastcgi.c from the distribution. This module appears
7805 to be maintained more through the Open Market channels and should
7806 continue to be easily available at http://www.fastcgi.com/
7808 *) Fixed bug in modules/Makefile that wouldn't allow building in more
7809 than one subdirectory (or cleaning, either). [Jeremy Laidman]
7811 *) mod_info assumed that the config files were relative to ServerRoot.
7814 *) CGI scripts called as an error document resulting from failed
7815 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
7817 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
7820 *) Properly check errno to prevent display of a directory index
7821 when server receives a long enough URL to confuse stat().
7824 *) Several security enhancements to suexec wrapper. It is _highly_
7825 recommended that previously installed versions of the wrapper
7826 be replaced with this version. [Randy Terbush, Jason Dour]
7828 - ~user execution now properly restricted to ~user's home
7829 directory and below.
7830 - execution restricted to UID/GID > 100
7831 - restrict passed environment to known variables
7832 - call setgid() before initgroups() (portability fix)
7833 - remove use of setenv() (portability fix)
7835 *) Add HTTP/1.0 response forcing. [Ben Laurie]
7837 *) Add access control via environment variables. [Ben Laurie]
7839 *) Add rflush() function. [Alexei Kosut]
7841 *) remove duplicate pcalloc() call in new_connection().
7843 *) Fix incorrect comparison which could allow number of children =
7844 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
7845 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
7847 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
7848 AIX PS/2, CONVEXOS. [Jim Jagielski]
7850 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
7851 It's more portable. [Martin Kraemer]
7853 *) Replace references to make in Makefile.tmpl with $(MAKE).
7856 *) Add ProxyBlock directive w/IP address caching. Add IP address
7857 caching to NoCache directive as well. ProxyBlock works with all
7858 handlers; NoCache now also works with FTP for anonymous logins.
7859 Still more code cleanup. [Chuck Murcko]
7861 *) Add "header parse" API hook [Ben Laurie]
7863 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
7865 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
7867 *) Correctly allow access and auth directives in <Files> sections in
7868 server config files. [Alexei Kosut]
7870 *) Fix bug with ServerPath that could cause certain files to be not
7871 found by the server. [Alexei Kosut]
7873 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
7874 double-quote from text and so that it properly checks for unsupported
7875 status codes using the new index_of_response interface. [Roy Fielding]
7877 *) Multiple fixes to the lingering_close code in order to avoid being
7878 interrupted by a stray timeout, to avoid lingering on a connection
7879 that has already been aborted or never really existed, to ensure that
7880 we stop lingering as soon as any error condition is received, and to
7881 prevent being stuck indefinitely if the read blocks. Also improves
7882 reporting of error conditions. [Marc Slemko and Roy Fielding]
7884 *) Fixed initialization of parameter structure for sigaction.
7885 [mgyger@itr.ch, Adrian Filipi-Martin]
7887 *) Fixed reinitializing the parameters before each call to accept and
7888 select, and removed potential for infinite loop in accept.
7889 [Roy Fielding, after useful PR from adrian@virginia.edu]
7891 *) Fixed condition where, if a child fails to fork, the scoreboard would
7892 continue to say SERVER_STARTING forever. Eventually, the main process
7893 would refuse to start new children because count_idle_servers() will
7894 count those SERVER_STARTING entries and will always report that there
7895 are enough idle servers. [Phillip Vandry]
7897 *) Fixed bug in bcwrite regarding failure to account for partial writes.
7898 Avoided calling bflush() when the client is pipelining requests.
7899 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
7901 *) Added description of "." mode in server-status [Jim Jagielski]
7903 Changes with Apache 1.2b4
7905 *) Fix possible race condition in accept_mutex_init() that
7906 could leave a small security hole open allowing files to be
7907 overwritten in cases where the server UID has write permissions.
7910 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
7912 *) Fix portablity problem in util_script where ARG_MAX may not be
7913 defined for some systems.
7915 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
7918 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
7919 style magic #! token for better script portability. [Garey Smiley]
7921 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
7922 execution for ~userdir CGI. [Jason Dour]
7924 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
7926 *) Fix month off by one in suexec wrapper logging.
7928 Changes with Apache 1.2b3:
7930 *) Fix error in mod_cgi which could cause resources not to be properly
7931 freed, or worse. [Dean Gaudet]
7933 *) Fix find_string() NULL pointer dereference. [Howard Fear]
7935 *) Add set_flag_slot() at the request of Dirk and others.
7938 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
7940 *) Add changes to improve the error message given for invalid
7941 ServerName parameters. [Dirk vanGulik]
7943 *) Add "Authoritative" directive for Auth modules that don't
7944 currently have it. This gives admin control to assign authoritative
7945 control to an authentication scheme and allow "fall through" for
7946 those authentication modules that aren't "Authoritative" thereby
7947 allowing multiple authentication mechanisms to be chained.
7950 *) Remove requirement for ResourceConfig/AccessConfig if not using
7951 the three config file layout. [Randy Terbush]
7953 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
7955 *) Changes to suexec wrapper to fix the following problems:
7956 1. symlinked homedirs will kill ~userdirs.
7957 2. initgroups() on Linux 2.0.x clobbers gr->grid.
7958 3. CGI command lines paramters problems
7959 4. pw-pwdir for "docroot check" still the httpd user's pw record.
7960 [Randy Terbush, Jason Dour]
7962 *) Change create_argv() to accept variable arguments. This fixes
7963 a problem where arguments were not getting passed to the CGI via
7964 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
7966 *) Collapse multiple slashes in path URLs to properly apply
7967 handlers defined by <Location>. [Alexei Kosut]
7969 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
7971 *) Improve the accuracy of request duration timings by setting
7972 r->request_time in read_request_line() instead of read_request().
7975 *) Reset timeout while reading via get_client_block() in mod_cgi.c
7976 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
7978 *) Add the ability to pass different Makefile.tmpl files to Configure
7979 using the -make flag. [Rob Hartill]
7981 *) Fix coredump triggered when sending a SIGHUP to the server caused
7982 by an assertion failure, in turn caused by an uninitialised field in a
7986 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
7987 PATH_INFO from previous versions of Apache (in certain situations,
7988 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
7989 [later removed in 1.2b11]
7991 *) Add rwrite() function to API to allow for sending strings of
7992 arbitrary length. [Doug MacEachern]
7994 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
7996 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
7997 NeXT. [Jim Jagielski]
7999 *) Removed recent modification to promote the status code on internal
8000 redirects, since the correct fix was to change the default log format
8001 in mod_log_config so that it outputs the original status. [Rob Hartill]
8003 Changes with Apache 1.2b2:
8005 *) Update set_signals() to use sigaction() for setting handlers.
8006 This appears to fix a re-entrant problem in the seg_fault()
8007 bus_error() handlers. [Randy Terbush]
8009 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
8011 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
8013 *) proxy_http.c bugfixes: [Chuck Murcko]
8014 1) fixes possible NULL pointer reference w/NoCache
8015 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
8016 host would cache nothing if it was in the local domain,
8017 and the local domain was in the NoCache list)
8018 3) Adds Host: header when not available
8019 4) Some code cleanup and clarification
8021 *) mod_include.c bugfixes:
8022 1) Fixed an ommission that caused include variables to not
8023 be parsed in config errmsg directives [Howard Fear]
8024 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
8025 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
8026 4) Allow backslash-escaping to all quoted text
8027 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
8028 5) Pass variable to command line if not set in XSSI's env
8031 *) Fix infinite loop when processing Content-language lines in
8032 type-map files. [Alexei Kosut]
8034 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
8036 *) Fixed problem in set_[user|group] that prevented CGI execution
8037 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
8039 *) Added PORTING information file. [Jim Jagielski]
8041 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
8043 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
8045 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
8046 USE_FCNTL_SERIALIZED_ACCEPT was intended.
8048 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
8049 which caused problems of systems where socket s_addr is >32bits.
8051 *) Added comment to explain (r->chunked = 1) side-effect in
8052 http_protocol.c [Roy Fielding]
8054 *) Replaced use of index() in mod_expires.c with more appropriate
8055 and portable isdigit() test. [Ben Laurie]
8057 *) Updated Configure for ...
8058 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
8059 *-dg-dgux* (bad pattern match)
8060 QNX (DEF_WANTHSREGEX=yes)
8061 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
8064 and added some user diagnostic info. [Ben Laurie]
8066 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
8067 for better portability. [Jim Jagielski]
8069 *) Updated helpers/GuessOS for ...
8070 SCO 5 (recognize minor releases)
8071 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
8072 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
8073 IRIX64 (-sgi-irix64)
8074 ULTRIX (-unknown-ultrix)
8075 SINIX (-whatever-sysv4)
8076 NCR Unix (-ncr-sysv4)
8077 and fixed something in helpers/PrintPath [Ben Laurie]
8079 Changes with Apache 1.2b1
8081 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
8083 Changes with Apache 1.1.1
8085 *) Fixed bug where Cookie module would make two entries in the
8086 logfile for each access [Mark Cox]
8088 *) Fixed bug where Redirect in .htaccess files would cause memory
8089 leak. [Nathan Neulinger]
8091 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
8093 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
8095 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
8097 Changes with Apache 1.1.0
8099 *) Bring NeXT support up to date. [Takaaki Matsumoto]
8101 *) Bring QNX support up to date. [Ben Laurie]
8103 *) Make virtual hosts default to main server keepalive parameters.
8104 [Alexei Kosut, Ben Laurie]
8106 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
8108 *) Fix missing address family for connect, also remove unreachable statement
8109 in mod_proxy. [Ben Laurie]
8111 *) mod_env now turned on by default in Configuration.tmpl.
8113 *) Bugs which were fixed:
8114 a) yet more mod_proxy bugs [Ben Laurie]
8115 b) CGI works again with inetd [Alexei Kosut]
8116 c) Leading colons were stripped from passwords [osm@interguide.com]
8117 d) Another fix to multi-method Limit problem [jk@tools.de]
8119 Changes with Apache 1.1b4
8121 *) r->bytes_sent variable restored. [Robert Thau]
8123 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
8125 *) More possibly unsecure programs removed from the support directory.
8127 *) More mod_auth_msql authentication improvements.
8129 *) VirtualHosts based on Host: headers no longer conflict with the
8132 *) OS/2 compatibility enhancements. [Gary Smiley]
8134 *) POST now allowed to directory index CGI scripts.
8136 *) Actions now work with files of the default type.
8138 *) Bugs which were fixed:
8139 a) more mod_proxy bugs
8140 b) early termination of inetd requests
8141 c) compile warnings on several systems
8142 d) problems when scripts stop reading output early
8144 Changes with Apache 1.1b3
8146 *) Much of cgi-bin and all of cgi-src has been removed, due to
8147 various security holes found and that we could no longer support
8150 *) The "Set-Cookie" header is now special-cased to not merge multiple
8151 instances, since certain popular browsers can not handle multiple
8152 Set-Cookie instructions in a single header. [Paul Sutton]
8154 *) rprintf() added to buffer code, occurrences of sprintf removed.
8157 *) CONNECT method for proxy module, which means tunneling SSL should work.
8158 (No crypto needed) Also a NoCache config directive.
8160 *) Several API additions: pstrndup(), table_unset() and get_token()
8161 functions now available to modules.
8163 *) mod_imap fixups, in particular Location: headers are now complete
8166 *) New "info" module which reports on installed module set through a
8167 special URL, a la mod_status.
8169 *) "ServerPath" directive added - allows for graceful transition
8170 for Host:-header-based virtual hosts.
8172 *) Anonymous authentication module improvements.
8174 *) MSQL authentication module improvements.
8176 *) Status module design improved - output now table-based. [Ben Laurie]
8178 *) htdigest utility included for use with digest authentication
8181 *) mod_negotiation: Accept values with wildcards to be treated with
8182 less priority than those without wildcards at the same quality
8183 value. [Alexei Kosut]
8185 *) Bugs which were fixed:
8186 a) numerous mod_proxy bugs
8187 b) CGI early-termination bug [Ben Laurie]
8188 c) Keepalives not working with virtual hosts
8189 d) RefererIgnore problems
8190 e) closing fd's twice in mod_include (causing core dumps on
8191 Linux and elsewhere).
8193 Changes with Apache 1.1b2
8196 a) core dumps in mod_digest
8197 b) truncated hostnames/ip address in the logs
8198 c) relative URL's in mod_imap map files
8200 Changes with Apache 1.1b1
8202 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
8204 Changes with Apache 1.0.3
8206 *) Internal redirects which occur in mod_dir.c now preserve the
8207 query portion of a request (the bit after the question mark).
8210 *) Escape active characters '<', '>' and '&' in html output in
8211 directory listings, error messages and redirection links.
8214 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
8216 *) Fix for POSIX compliance in waiting for processes in alloc.c.
8219 *) setsockopt no longer takes a const declared argument [Martijn Koster]
8221 *) Reset timeout timer after each successful fwrite() to the network.
8222 This patch adds a reset_timeout() procedure that is called by
8223 send_fd() to reset the timeout ever time data is written to the net.
8226 *) timeout() signal handler now checks for SIGPIPE and reports
8227 lost connections in a more user friendly way. [Rob Hartill]
8229 *) Location of the "scoreboard" file which used to live in /tmp is
8230 now configurable (for OSes that can't use mmap) via ScoreBoardFile
8231 which works similar to PidFile (in httpd.conf) [Rob Hartill]
8233 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
8235 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
8236 which caused a SEGV with cookies enabled
8238 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
8241 *) Log the UNIX textual error returned by some system calls, in
8242 particular errors from accept() [David Robinson]
8244 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
8246 Changes with Apache 1.0.2
8248 *) patch to get Apache compiled on UnixWare 2.x, recommended as
8249 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
8251 *) Fix get_basic_auth_pw() to set the auth_type of the request.
8254 *) past changes to http_config.c to only use the
8255 setrlimit function on systems defining RLIMIT_NOFILE
8256 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
8257 for SUNOS and prototypes the needed functions.
8259 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
8262 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
8264 *) Merge multiple headers from CGI scripts instead of taking last
8265 one. [David Robinson]
8267 *) Add support for SCO 5. [Ben Laurie]
8269 Changes with Apache 1.0.1
8271 *) Silence mod_log_referer and mod_log_agent if not configured
8274 *) Recursive includes can occur if the client supplies PATH_INFO data
8275 and the server provider uses relative links; as file.html
8276 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
8278 *) The replacement for initgroups() did not call {set,end}grent(). This
8279 had two implications: if anything else used getgrent(), then
8280 initgroups() would fail, and it was consuming a file descriptor.
8283 *) On heavily loaded servers it was possible for the scoreboard to get
8284 out of sync with reality, as a result of a race condition.
8285 The observed symptoms are far more Apaches running than should
8286 be, and heavy system loads, generally followed by catastrophic
8287 system failure. [Ben Laurie]
8289 *) Fix typo in license. [David Robinson]
8291 Changes with Apache 1.0.0 23 Nov 1995
8293 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
8295 Changes with Apache 0.8.16 05 Nov 1995
8297 *) New man page for 'httpd' added to support directory [David Robinson]
8299 *) .htgroup files can have more than one line giving members for a
8300 given group (each must have the group name in front), for NCSA
8301 back-compatibility [Robert Thau]
8303 *) Mutual exclusion around accept() is on by default for SVR4 systems
8304 generally, since they generally can't handle multiple processes in
8305 accept() on the same socket. This should cure flaky behavior on
8306 a lot of those systems. [David Robinson]
8308 *) AddType, AddEncoding, and AddLanguage directives take multiple
8309 extensions on a single command line [David Robinson]
8311 *) UserDir can be disabled for a given virtual host by saying
8312 "UserDir disabled" in the <VirtualHost> section --- it was a bug
8313 that this didn't work. [David Robinson]
8315 *) Compiles on QNX [Ben Laurie]
8317 *) Corrected parsing of ctime time format [David Robinson]
8319 *) httpd does a perror() before exiting if it can't log its pid
8320 to the PidFile, to make diagnosing the error a bit easier.
8323 *) <!--#include file="..."--> can no longer include files in the
8324 parent directory, for NCSA back-compatibility. [David Robinson]
8326 *) '~' is *not* escaped in URIs generated for directory listings
8329 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
8331 *) Fixed bug involving handling URIs with escaped %-characters
8332 in redirects [David Robinson]
8334 Changes with Apache 0.8.15 14 Oct 1995
8336 *) Switched to new, simpler license
8338 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
8340 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
8342 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
8344 *) Correctly handles internal redirects to files with names containing '%'
8347 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
8349 *) Use geteuid() rather than getuid() to see if we have root privilege,
8350 so that server correctly resets privilege if run setuid root. [Andrew
8353 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
8356 *) Fix relative URLs in imagemap files [Randy Terbush]
8358 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
8361 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
8362 entries all name the same one. [David Robinson]
8364 *) Fix directory listings with filenames containing unusual characters
8367 *) Better URI-escaping for generated URIs in directories with filenames
8368 containing unusual characters [Ben Laurie]
8370 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
8372 *) Unblock alarms on error return from spawn_child() [David Robinson]
8374 *) Sample Config files have extra note for SCO users [Ben Laurie]
8376 *) Configuration has note for HP-UX users [Rob Hartill]
8378 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
8380 *) Nuked bogus #define in httpd.h [David Robinson]
8382 *) Better test for whether a system has setrlimit() [David Robinson]
8384 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
8386 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
8389 Changes with Apache 0.8.14 19 Sep 1995
8391 *) Compiles on SCO ODT 3.0 [Ben Laurie]
8393 *) AddDescription works (better) [Ben Laurie]
8395 *) Leaves an intelligible error diagnostic when it can't set group
8396 privileges on standalone startup [Andrew Wilson]
8398 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
8399 that machine, which claims to be BSD but does not support RLIMIT.
8402 *) gcc -Wall no longer complains about an unused variable when util.c
8403 is compiled with -DMINIMAL_DNS [Andrew Wilson]
8405 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
8407 Changes with Apache 0.8.13 07 Sep 1995
8409 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
8411 *) Have built-in imagemap code recognize & honor Point directive [James
8414 *) Generate cleaner directory listings in directories with a mix of
8415 long and short filenames [Rob Hartill]
8417 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
8419 *) Properly default ServerName for virtual servers [Robert Thau]
8421 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
8422 Paul Richards and a cast of thousands...]
8424 *) On self-identified BSD systems (we don't try to guess any more),
8425 allocate a few extra file descriptors per virtual host with setrlimit,
8426 if we can, to avoid running out. [Randy Terbush]
8428 *) Write 22-character lock file name into buffer with enough space
8429 on startup [Konstantin Olchanski]
8431 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
8434 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
8436 *) Suppress -Wall warning by initializing variable in negotiation code
8437 [Tobias Weingartner]
8439 Changes with Apache 0.8.12 31 Aug 1995
8441 *) Doesn't pause three seconds after including a CGI script which is
8442 too slow to die off (this is done by not even trying to kill off
8443 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
8444 after the entire document has been processed). [Robert Thau]
8446 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
8448 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
8450 *) Allows .htaccess files to override <Directory> sections naming the
8451 same directory [David Robinson]
8453 *) Removed an efficiency hack in sub_req_lookup_uri which was
8454 causing certain extremely marginal cases (e.g., ScriptAlias of a
8455 *particular* index.html file) to fail. [David Robinson]
8457 *) Doesn't log an error when the requested URI requires
8458 authentication, but no auth header line was supplied by the
8459 client; this is a normal condition (the client doesn't no auth is
8460 needed here yet). [Robert Thau]
8462 *) Behaves more sanely when the name server loses its mind [Sean Welch]
8464 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
8466 *) RFC931 code no longer passes out name of prior clients on current
8467 requests if the current request came from a server that doesn't
8468 do RFC931. [David Robinson]
8470 *) Configuration script accepts "Module" lines with trailing whitespace.
8473 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
8475 *) Cleaned up comments in mod_cgi.c [Robert Thau]
8477 Changes with Apache 0.8.11 24 Aug 1995
8479 *) Wildcard <Directory> specifications work. [Robert Thau]
8481 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
8483 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
8484 the file being requested itself, in addition to the directories leading
8485 up to it. [Robert Thau]
8487 *) Logs access failures due to symlink checks or invalid client address
8488 in the error log [Roy Fielding, Robert Thau]
8490 *) Symlink checks deal correctly with systems where lstat of
8491 "/path/to/some/link/" follows the link. [Thau, Fielding]
8493 *) Doesn't reset DirectoryIndex to 'index.html' when
8494 other directory options are set in a .htaccess file. [Robert Thau]
8496 *) Clarified init code and nuked bogus warning in mod_access.c
8499 *) Corrected several directives in sample srm.conf
8500 --- includes corrections to directory indexing icon-related directives
8501 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
8502 icons for encodings right, and turning on AddEncoding by default).
8505 *) Corrected descriptions of args to AddIcon and AddAlt in command table
8508 *) INSTALL & README mention "contributed modules" directory [Brian
8511 *) Fixed English in the license language... "for for" --> "for".
8514 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
8515 mod_alias.c, merging it almost completely with handling of Alias, and
8516 adding a 'notes' field to the request_rec which allows the CGI module
8517 to discover whether the Alias module has put this request through
8518 ScriptAlias (which it needs to know for back-compatibility, as the old
8519 NCSA code did not check Options ExecCGI in ScriptAlias directories).
8522 Changes with Apache 0.8.10 18 Aug 1995
8524 *) AllowOverride applies to the named directory, and not just
8525 subdirectories. [David Robinson]
8527 *) Do locking for accept() exclusion (on systems that need it)
8528 using a special file created for the purpose in /usr/tmp, and
8529 not the error log; using the error log causes real problems
8530 if it's NFS-mounted; this is known to be the cause of a whole
8531 lot of "server hang" problems with Solaris. [David Robinson;
8532 thanks to Merten Schumann for help diagnosing the problem].
8534 Changes with Apache 0.8.9 12 Aug 1995
8536 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
8538 *) Nested includes see environment variables of the including document,
8539 for NCSA bug-compatibility (some sites have standard footer includes
8540 which try to print out the last-modified date). [Eric Hagberg/Robert
8543 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
8544 URI as a CGI script, even if it would have been treated as something
8545 else if requested directly, for NCSA back-compatibility. (Note that
8546 this means that people who know the name of the script can see the
8547 code just by asking for it). [Robert Thau]
8549 *) New version of dbmmanage script included in support directory as
8552 *) Check if scoreboard file couldn't be opened, and say so, rather
8553 then going insane [David Robinson]
8555 *) POST to CGI works on A/UX [Jim Jagielski]
8557 *) AddIcon and AddAlt commands work properly [Rob Hartill]
8559 *) NCSA server push works properly --- the Arena bug compatibility
8560 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
8561 if you still want the workaround). [Rob Hartill]
8563 *) If client didn't submit any Accept-encodings, ignore encodings in
8564 content negotiation. (NB this will all have to be reworked anyway
8565 for the new HTTP draft). [Florent Guillaume]
8567 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
8569 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
8571 *) Give Redirect priority over Alias, for NCSA bug compatibility
8574 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
8575 paralleling earlier bug fix for CGI [David Robinson]
8577 *) If DBM auth is improperly configured, report a server error and don't
8580 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
8581 it seems to work well enough without it (even in a 10 hits/sec
8582 workout), and the overhead for the locking under A/UX is
8583 alarmingly high (though it is very low on other systems).
8584 [Eric Hagberg, Jim Jagielski]
8586 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
8588 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
8589 Behlendorf/Eric Hagberg]
8591 *) More improvements to default Configuration for A/UX [Jim Jagielski]
8593 *) Compiles clean on NEXT [Rob Hartill]
8595 *) Compiles clean on SGI [Robert Thau]
8597 Changes with Apache 0.8.8 08 Aug 1995
8599 *) SunOS library prototypes now never included unless explicitly
8600 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
8601 people using GNU libc on SunOS are screwed by prototypes for the
8604 (Those who wish to compile clean with gcc -Wall on a standard
8605 SunOS setup need the prototypes, and may obtain them using
8606 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
8607 with nonstandard libraries are presumably competent to make their
8610 *) Strips trailing '/' characters off both args to the Alias command,
8611 to make 'Alias /foo/ /bar/' work.
8613 Changes with Apache 0.8.7 03 Aug 1995
8615 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
8616 [reported by David Robinson]
8618 *) Compiles clean on OSF/1 [David Robinson]
8620 *) Added some of the more recent significant changes (AddLanguage stuff,
8621 experimental LogFormat support) to CHANGES file in distribution root
8624 Changes with Apache 0.8.6 02 Aug 1995
8626 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
8627 (If you actually wanted a conditional GET which bypassed the cache, you
8628 couldn't get it). [Reported by Roy Fielding]
8630 *) Properly terminate headers on '304 Not Modified' replies to conditional
8631 GETs --- no browser we can find cares much, but the CERN proxy chokes.
8632 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
8634 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
8636 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
8637 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
8638 and older versions don't set the __SUNPRO_C preprocessor variable). On
8639 all other systems, these are never used anyway. [Reported by Mark Cox].
8641 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
8643 Changes with Apache 0.8.5 01 Aug 1995
8645 *) Added last-minute configurable log experiment, as optional module
8647 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
8648 properly. (One-line fix to http_protocol.c).
8650 *) Work around bogus behavior when reloading from Netscape.
8651 It's Netscape's bug --- for some reason they expect a request with
8652 If-modified-since: to not function as a conditional GET if it also
8653 comes with Pragma: no-cache, which is way out of line with the HTTP
8654 spec (according to Roy Fielding, the redactor).
8656 *) Added parameter to set maximum number of server processes.
8658 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
8661 *) IdentityCheck bugfix [Chuck Murcko].
8663 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
8665 *) More sample config file corrections; add extension to AddType for
8666 *.asis, move AddType generic description to its proper place, and
8667 fix miscellaneous typos. [ Alexei Kosut ]
8669 *) Deleted the *other* reference to the regents from the Berkeley
8670 legal disclaimer (everyplace).
8672 *) Nuked Shambhala name from src/README; had already cleaned it out
8675 Changes with Apache 0.8.4
8677 *) Changes to server-pool management parms --- renamed current
8678 StartServers to MinSpareServers, created separate StartServers
8679 parameter which means what it says, and renamed MaxServers to
8680 MaxSpareServers (though the old name still works, for NCSA 1.4
8681 back-compatibility). The old names were generally regarded as
8682 too confusing. Also altered "docs" in sample config files.
8684 *) More improvements to default config files ---
8685 sample directives (commented out) for XBitHack, BindAddress,
8686 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
8687 defaults, AddTypes for send-as-is and imagemap magic types, and
8688 improvements to samples for DirectoryIndex [Alexei Kosut]
8690 *) Yet more improvements to default config files --- changes to
8691 Alexei's sample AddLanguage directives, and sample LanguagePriority
8692 [ Florent Guillaume ]
8694 *) Set config file locations properly if not set in httpd.conf
8697 *) Don't escape URIs in internal redirects multiple times; don't
8698 do that when translating PATH_INFO to PATH_TRANSLATED either.
8701 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
8703 Changes with Apache 0.8.3
8705 *) Edited distribution README to *briefly* summarize installation
8706 procedures, and give a pointer to the INSTALL file in the src/
8709 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
8710 recent NCSA distributions.
8712 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
8713 exist for the same directory, use both and don't segfault. [Reported
8716 *) Proper makefile dependencies [David Robinson]
8718 *) Note (re)starts in error log --- reported by Rob Hartill.
8720 *) Only call no2slash() after get_path_info() has been done, to
8721 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
8722 reported by Andrew Wilson, though this one is probably a real bug]
8724 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
8725 dump core when Referer is not supplied. [Randy Terbush]
8727 *) Lightly edited sample config files to refer people to our documentation
8728 instead of NCSA's, and to list Rob McCool as *original* author (also
8729 deleted his old, and no doubt non-functional email address). Would be
8730 nice to have examples of new features...
8732 Changes with Apache 0.8.2 19 Jul 1995
8734 *) Added AddLanuage code [Florent Guillaume]
8736 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
8738 *) All sorts of problems when MultiViews finds a directory. It would
8739 be nice if mod_dir.c was robust enough to handle that, but for now,
8740 just punt. [reported by Brian Behlendorf]
8742 *) Wait for all children on restart, to make sure that the old socket
8743 is gone and we can reopen it. [reported by Randy Terbush]
8745 *) Imagemap module is enabled in default Configuration
8747 *) RefererLog and UserAgentLog modules properly default the logfile
8750 *) Mark Cox's mod_cookies added to the distribution as an optional
8751 module (commented out in the default Configuration, and noted as
8752 an experiment, along with mod_dld). [Mark Cox]
8754 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
8756 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
8758 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
8760 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
8763 Changes with Apache 0.8.1
8765 *) New imagemap module [Randy Terbush]
8767 *) Replacement referer log module with NCSA-compatible RefererIgnore
8768 [Matthew Gray again]
8770 *) Don't mung directory listings with very long filenames.
8773 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
8775 *) New config script. See INSTALL for info. [Robert Thau]
8777 *) Scoreboard mechanism for regulating the number of extant server
8778 processes. MaxServers and StartServers defaults are the same as
8779 for NCSA, but the meanings are slightly different. (Actually,
8780 I should probably lower the MaxServers default to 10).
8782 Before asking for a new connection, each server process checks
8783 the number of other servers which are also waiting for a
8784 connection. If there are more than MaxServers, it quietly dies
8785 off. Conversely, every second, the root, or caretaker, process
8786 looks to see how many servers are waiting for a new connection;
8787 if there are fewer than StartServers, it starts a new one. This
8788 does not depend on the number of server processes already extant.
8789 The accounting is arranged through a "scoreboard" file, named
8790 /tmp/htstatus.*, on which each process has an independent file
8791 descriptor (they need to seek without interference).
8793 The end effect is that MaxServers is the maximum number of
8794 servers on an *inactive* server machine, but more will be forked
8795 off to handle unusually heavy loads (or unusually slow clients);
8796 these will die off when they are no longer needed --- without
8797 reverting to the overhead of full forking operation. There is a
8798 hard maximum of 150 server processes compiled in, largely to
8799 avoid forking out of control and dragging the machine down.
8800 (This is arguably too high).
8802 In my server endurance tests, this mechanism did not appear to
8803 impose any significant overhead, even after I forced it to put the
8804 scoreboard file on a normal filesystem (which might have more
8805 overhead than tmpfs). [Robert Thau]
8807 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
8810 *) Read .htaccess files even in directory with <Directory> section.
8811 (Former incompatibility noted on mailing list, now fixed). [Robert
8814 *) "HEAD /" gives the client a "Bad Request" error message, rather
8815 than trying to send no body *and* no headers. [Cliff Skolnick].
8817 *) Don't produce double error reports for some very obscure cases
8818 mainly involving auth configuration (the "all modules decline to
8819 handle" case which is a sure sign of a server bug in most cases,
8820 but also happens when authentication is badly misconfigured).
8823 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
8824 it's *for*, and this sort of thing really shouldn't be cluttering
8825 up the Makefile). [Robert Thau]
8827 *) Incidental code cleanups in http_main.c --- stop dragging
8828 sa_client around; just declare it where used. [Robert Thau]
8830 *) Another acc-related fix. (It doesn't like const char
8831 in some places...). [Mark Cox]
8833 Changes with Shambhala 0.6.1 13 Jul 1995
8835 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
8836 Also, fixed auth typo in http_protocol.c unmasked by this fix.
8838 *) Compiles clean with acc on SunOS [Paul Sutton]
8840 *) Reordered modules in modules.c so that Redirect takes priority
8841 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
8842 believe it or not, he has an actual site with a ScriptAlias and
8843 a Redirect declared for the *exact same directory*. Even *my*
8844 compatibility fetish wouldn't motivate me to fix this if the fix
8845 required any effort, but it doesn't, so what the hey.
8847 *) Fixed to properly default several server_rec fields for virtual
8848 servers from the corresponding fields in the main server_rec.
8849 [Cliff Skolnick --- 'port' was a particular irritant].
8851 *) No longer kills off nph- child processes before they are
8852 finished sending output. [Matthew Gray]
8854 Changes with Shambhala 0.6.0 10 Jul 1995
8856 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
8857 the connection to the client in an "aborted" state, but otherwise
8858 allow whatever handlers are running to clean up. hard_timeout()s
8859 abort the request in progress completely; anything not tied to some
8860 resource pool cleanup will leak. They're still around because I
8861 haven't yet come up with a more elegant way of handling
8862 timeouts when talking to something that isn't the client. The
8863 default_handler and the dir_handler now use soft timeouts, largely
8864 so I can test the feature. [Robert Thau]
8866 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
8867 the case of log handlers dying prematurely is probably handled VERY
8868 gracelessly at this point, and if the logger stops reading input,
8869 the server will hang. (It is known to correctly restart the
8870 logging process on server restart; this is (should be!) going through
8871 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
8872 script). [Robert Thau]
8874 *) asis files supported (new module). [Robert Thau]
8876 *) IdentityCheck code is compiled in, but has not been tested. (I
8877 don't know anyone who runs identd). [Robert Thau]
8879 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
8880 came in with the request, for NCSA bug-compatibility. [Robert Thau]
8882 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
8884 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
8885 as timeouts are not in scope. [Robert Thau]
8887 *) quoted-string args in config files now handled correctly (doesn't drop
8888 the last character). [Robert Thau; reported by Randy Terbush]
8890 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
8891 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
8893 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
8894 default default type); the former default default behavior when all
8895 type-checkers defaulted had been a core dump. [Paul Sutton]
8897 *) Copy filenames out of the struct dirent when indexing
8898 directories. (On Linux, readdir() returns a pointer to the same
8899 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
8901 Changes with Shambhala 0.5.3 [not released]
8903 *) Default response handler notes "file not found" in the error log,
8904 if the file was not found. [Cliff Skolnick].
8906 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
8907 code no longer sets up bogus PATH_INFO which fakes out the directory
8908 handler). [Cliff Skolnick]
8910 Changes with Shambhala 0.5.2 06 Jul 1995
8912 *) Changes to http_main.c --- root server no longer plays silly
8913 games with SIGCHLD, and so now detects and replaces dying
8914 children. Child processes just die on SIGTERM, without taking
8915 the whole process group with them. Potential problem --- if any
8916 child process refuses to die, we hang in restart.
8917 MaxRequestsPerChild may still not work, but it certainly works
8918 better than it did before this! [Robert Thau]
8920 *) mod_dir.c bug fixes: ReadmeName and HeaderName
8921 work (or work better, at least); over-long description lines
8922 properly terminated. [Mark Cox]
8924 *) http_request.c now calls unescape_url() more places where it
8925 should [Paul Sutton].
8927 *) More directory handling bugs (reported by Cox)
8928 Parent Directory link is now set correctly. [Robert Thau]
8930 Changes with Shambhala 0.5.1 04 Jul 1995
8932 *) Generalized cleanup interface in alloc.c --- any function can be
8933 registered with alloc.c as a cleanup for a resource pool;
8934 tracking of files and file descriptors has been reimplemented in
8935 terms of this interface, so I can give it some sort of a test.
8938 *) More changes in alloc.c --- new cleanup_for_exec() function,
8939 which tracks down and closes all file descriptors which have been
8940 registered with the alloc.c machinery before the server exec()s a
8941 child process for CGI or <!--#exec-->. CGI children now get
8942 started with exactly three file descriptors open. Hopefully,
8943 this cures the problem Rob H. was having with overly persistent
8944 CGI connections. [Robert Thau]
8946 *) Mutual exclusion around the accept() in child_main() --- this is
8947 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
8948 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
8949 This uses fcntl(F_SETLK,...) on the error log descriptor because
8950 flock() on that descriptor won't work on systems which have BSD
8951 flock() semantics, including (I think) Linux 1.3 and Solaris.
8953 This does work on SunOS (when the server is idle, only one
8954 process in the pool is waiting on accept()); it *ought* to work
8955 on the other systems. [Robert Thau]
8957 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
8959 *) sizeof(*sa_client) bugfix from [Rob Hartill]
8961 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
8963 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
8964 be unnecessary if I go to the revised timeout-handling scheme).
8967 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
8968 string) even if none came in with the request. [Robert Thau]
8970 *) CHANGES file added to distribution ;-).
8972 Changes with Shambhala 0.4.5
8974 *) mod_dld --- early dynamic loading support [rst]
8975 *) Add wildcard content handlers for XBITHACK; default_hander now
8976 invoked with that mechanism (as a handler hanging off mod_core) [rst]
8977 *) XBITHACK supported as a wildcard content-handler, and
8978 configurable at run-time (not just at compile time, as in the
8979 "patchy server" releases) [rst]
8981 Changes with Shambhala 0.4.4 30 Jun 1995
8983 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
8984 *) Handle Addtype x/y .z [rst, reported by Cox]
8986 Changes with Shambhala 0.4.3
8988 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
8989 synonymous [rst, terbush]
8991 Changes with Shambhala 0.4.1 28 Jun 1995
8993 *) First-cut virtual host implementation; some refit in the config
8994 reading code, and log management, was necessary to support this [rst]
8995 *) Sub-pool machinery, originally added to avoid excessive storage
8996 allocation on listings of large directories (which turned out to
8997 be the problem that the 0.3 storage accounting was added to
8998 find). Subrequests and mod_dir changed to use subpools. [rst]
8999 *) More memory debugging --- free list consistency checks. [rst]
9000 *) Added err_headers to request_rec, with support elsewhere [rst]
9001 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
9003 Changes with Shambhala 0.3 19 Jun 1995
9005 *) Switch ONE_PROCESS to a runtime command-line option (-X)
9006 *) Don't compile in mod_ai_backcompat by default
9007 *) Switch name of server from Apache to Shambhala in Makefile
9008 *) Add some accounting routines to track memory usage in the pools,
9011 Changes with Shambhala 0.2
9013 *) Set DOCUMENT_ROOT CGI variable
9014 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
9015 *) Add critical section protection to handling of cleanup structures
9017 *) Significant code reorg within the server core to group related
9018 functions together [rst]
9019 *) Correctly handle clients that hang up before sending any request
9021 *) Replace dying child processes. [rst]
9023 Changes with Shambhala 0.1 12 Jun 1995
9025 Major rewrite of the pre-existing "patchy server" codebase, by
9026 Robert Thau (rst). Significant portions of the server code, such
9027 as configuration-file handling and HTTP authentication support,
9028 were ripped out and rewritten from scratch. Code that was not
9029 completely rewritten was significantly altered.
9031 Major changes with this release include:
9033 *) Introduction of the module API; in request handling, the central
9034 machinery just dispatches to various modules, which actually do
9035 most of the work. Configuration handling is similar --- modules
9036 declare their own commands, and the central machinery just
9039 API features from shambhala/0.1 were substantially unchanged in
9040 Apache 1.0 and 1.1. (1.0 API features not yet present in this
9041 release, such as wildcard handlers and subpools, were added in
9042 subsequent Shambhala releases, and were also generally rst's
9045 *) This release included the following modules:
9047 mod_access (access control --- allow and deny directives),
9048 mod_alias (Alias and Redirect commands),
9049 mod_auth (straight HTTP authentication, based on flat-files)
9050 mod_auth_dbm (same, with dbm files)
9051 mod_cgi (CGI scripts and, in this release, ScriptAlias)
9052 mod_common_log (CLF access logs; later renamed mod_log_common)
9053 mod_dir (directory indexing)
9054 mod_include (server-side includes)
9055 mod_mime (AddType directives)
9056 mod_negotiation (content negotiation)
9057 mod_userdir (support for users' public_html directories)
9059 It also included a mod_ai_backcompat, which was a private hack
9060 for back-compatibility with rst's own AI-lab servers.
9062 All of these modules were substantially complete, and functional
9063 or nearly so (a few, which implemented features not in use at
9064 Thau's site, required patches of a few lines).
9066 *) sub-request machinery, to allow modules to determine how other
9067 modules would assign MIME types to a given file, or optionally
9068 serve its content (this is heavily used by mod_dir, mod_include
9069 and mod_negotiation).
9071 *) Resource pool system for keeping track of memory allocated and
9072 files opened in service of a particular request. Much of the
9073 code in the modules (when they weren't rewrites) was adjusted to
9074 replace a pervasive convention of using fixed-size buffers on
9075 the stack with an equally pervasive convention of using memory
9076 allocated with palloc().
9078 *) Reorganization of data structures associated with a given
9079 request to eliminate use of global variables and the troublesome
9080 unmunge_name function (used in NCSA and early Apache releases to
9081 attempt to determine the URI which mapped to a given filename
9082 --- a difficult proposition, given that it is easy to produce
9083 setups in which multiple URIs map to the same file).
9085 *) Source files renamed and rearranged
9087 *) Very simple pre-forking behavior --- parent process forked off a
9088 fixed number of children, and then just waited for SIGHUP.
9090 *) Other more minor changes too numerous to list.
9092 This release included modified versions of a lot of code from the
9093 Apache 0.6.4 public release, plus an early pre-forking patch
9094 codeveloped by Robert Thau and Rob Hartill.
9096 Changes with Apache 0.7.3 20 Jun 1995
9098 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
9099 were incorporated by Rob Hartill on the main branch while Robert Thau
9100 worked on the Shambhala rewrite above. Most were merged into the
9101 Shambala architecture after Apache 0.8.0.
9103 Changes with Apache 0.6.4 13 May 1995
9105 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
9108 Changes with Apache 0.5.1 10 Apr 1995
9110 Changes with Apache 0.4 02 Apr 1995
9112 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
9115 Changes with Apache 0.3 24 Mar 1995
9117 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
9120 Changes with Apache 0.2 18 Mar 1995
9122 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
9123 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
9124 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
