1 Changes with Apache 2.0.12-dev
3 *) Use "Basic" authentication instead of "basic" in ab, as the spec
4 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
6 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
7 without ever filling it out. This fixes PR 7271.
8 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
9 Cliff Woolley <cliffwoolley@yahoo.com>]
11 *) Add a couple of GCC attribute tags to printf style functions.
12 [Jon Travis <jtravis@covalent.net>]
14 *) Add the correct language tag for interoperation with the Taiwanese
15 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
17 *) Migrate the perchild MPM to use the new apr signal child, and
18 APR thread functions. [Ryan Bloom]
20 *) Close one copy of the CGI's stdout before creating the new process.
21 The CGI will still have stdout, because we have already dup'ed it.
22 This keeps Apache from waiting forever to send the results of a CGI
23 process that has forked a long-lived child process.
24 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
26 *) Remove the rest of the pthreads functions from the threaded MPM.
27 This requires the APR support for a signal thread that was just
30 *) Make mod_dir use a fixup for sending a redirect to the browser.
31 Before this, we were using a handler, which doesn't make much
32 sense, because the handler wasn't generating any data, it would
33 either return a redirect error code, or DECLINED. This fits the
34 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
36 *) Make the threaded MPM use APR threads instead of pthreads.
39 *) Get mod_tls to the point where it actually appears to work in all cases.
42 *) implement --enable-modules and --enable-mods-shared for "all" and
45 *) Move the threaded MPM to use APR locks instead of pthread locks.
48 *) Rename mpmt_pthread to threaded. This is more in line with the
49 fact that mpmt_pthread shouldn't be using pthreads directly, and
50 it is a smaller name that doesn't tie into anything.
53 *) Rename the module structures so that the exported symbol matches
54 the file name, and it is easier to automate the installation
55 process (generating LoadModule directives from the module filenames).
58 *) Remove the coalesce filter. With the ap_f* functions, this filter
59 is no longer needed. [Ryan Bloom]
61 Changes with Apache 2.0.11
63 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
64 added feature of allowing a uid/gid per child process. If no
65 uid/gid is specified, then Perchild behaves exactly like dexter.
68 *) Get perchild building again. [Ryan Bloom]
70 *) Don't disable threads just because we are using the prefork MPM.
71 If somebody wants to compile without threads, they must now add
72 --disable-threads to the configure command line. [Ryan Bloom]
74 *) Begin to move the calls to update_child_status into common code, so
75 that each individual MPM does not need to update the scoreboard itself.
78 *) Allow mod_tls to compile under Unix boxes where openssl has been
79 installed to the system include files.
80 [Gomez Henri <new-httpd@slib.fr>]
82 *) Cleanup the mod_tls configure process. This should remove any need
83 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
84 configure doesn't check that yet. [Ryan Bloom]
86 *) Add a very early prototype of SSL support (in mod_tls.c). It is
87 vital that you read modules/tls/README before attempting to build
90 *) Fix a potential seg fault on all platforms. David Reid fixed this
91 on BEOS, but the problem could happen anywhere, so we don't want
92 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
94 *) Add new LogFormat directive, %D, to log time it takes to serve a
95 request in microseconds. [Bill Stoddard]
97 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
98 SetOutputFilter. This corresponds nicely with the other Set
99 directives, which operate on containers while the Add* directives
100 tend to work directly on extensions. [Ryan Bloom]
102 *) Cleanup the header handling a bit. This uses the apr_brigade_*
103 functions for the buffering so that we don't need to compute
104 the length of the headers before we actually create the header
107 *) Allow filters to buffer data using the ap_f* functions. These have
108 become macros that resolve directly to apr_brigade_*.
111 *) Get the Unix MPM's to do a graceful restart again. If we are going
112 to register a cleanup with ap_cleanup_scoreboard, then we have to
113 kill the cleanup with the same function, and that function can't be
116 *) Install all required header files. Without these, it was not
117 possible to compile some modules outside of the server.
120 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
121 forward from 1.3 to 2.0, we missed a single line, which broke regex
122 aliases. [Ryan Bloom]
124 *) We have a poor abstraction in the protocol. This is a temporary
125 hack to fix the bug, but it will need to be fixed for real. If
126 we find an error while sending out a custom error response, we back
127 up to the first non-OK request and send the data. Then, when we send
128 the EOS from finalize_request_protocol, we go to the last request,
129 to ensure that we aren't sending an EOS to a request that has already
130 received one. Because the data is sent on a different request than
131 the EOS, the error text never gets sent down the filter stack. This
132 fixes the problem by finding the last request, and sending the data
133 with that request. [Ryan Bloom]
135 *) Make the server status page show the correct restart time, and
136 thus the proper uptime. [Ryan Bloom]
138 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
139 should reduce the amount of duplicate code that is required to
140 create CGI processes.
141 [Paul J. Reder <rederpj@raleigh.ibm.com>]
143 *) ap_new_connection() closes the socket and returns NULL if a socket
144 call fails. Usually this is due to a connection which has been
145 reset. [Jeff Trawick]
147 *) Move the Apache version information out of httpd.h and into release.h.
148 This is in preparation for the first tag with the new tag and release
151 *) Begin restructuring scoreboard code to enable adding back in
152 the ability to use IPC other than shared memory.
153 Get mod_status working on Windows again. [Bill Stoddard]
155 *) Make mod_status work with 2.0. This will work for prefork,
156 mpmt_pthread, and dexter. [Ryan Bloom]
158 *) Correct a typo in httpd.conf.
159 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
161 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
163 *) Get the correct IP address if ServerName isn't set and we can't
164 find a fully-qualified domain name at startup.
165 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
167 *) Make mod_cgid work with SuExec. [Ryan Bloom]
169 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
170 'extra' stat's for user/group since they should never occur, and now
171 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
172 volumes. [William Rowe]
174 *) Adopt apr features to simplify mod_includes. This changes the
175 behavior of the USER_NAME variable, unknown uid's are now reported
176 as USER_NAME="<unknown>" rather than the old user#000 result.
177 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
179 *) Adopt apr features for simplifing mod_userdir, and accept the new
180 Win32/OS2 exceptions without hiccuping. [William Rowe]
182 *) Replace configure --with-optim option by using and saving the
183 environment variable OPTIM instead. This is needed because configure
184 options do not support multiple flags separated by spaces.
187 *) Fix some byterange handling. If we get a byte range that looks like
188 "-999999" where that is past the end of the file, we should return
189 a PARTIAL CONTENT status code, and return the whole file as one big
190 byterange. This matches the 1.3 handling now. [Ryan Bloom]
192 *) Make the error bucket a real meta-data bucket. This means that the
193 bucket length is 0, and a read returns NULL data. If one of these
194 buckets is passed down after the headers are sent, this data will
195 just be ignored. [Greg Stein]
197 *) The prefork MPM wasn't killing child processes correctly if a restart
198 signal was received while the process was serving a request. The child
199 process would become the equivalent of a second parent process. If
200 we break out of the accept loop, then we need to do die after cleaning
201 up after ourselves. [Ryan Bloom]
203 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
204 restarts. [Ryan Bloom]
206 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
207 the most optimal APR_FINFO_wanted bits. This spares Win32 from
208 performing very expensive owner, group and permission lookups
209 and allows the server to function until these apr_finfo_t fields
210 are implemented under Win32. [William Rowe]
212 *) Support for typedsafe optional functions - that is functions exported by
213 optional modules, which, therefore, may or may not be present, depending
214 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
215 for sample code. [Ben Laurie]
217 *) filters can now report an HTTP error to the server. This is done
218 by sending a brigade where the first bucket is an error_bucket.
219 This bucket is a simple bucket that stores an HTTP error and
220 a string. Currently the string is not used, but it may be needed
221 to output an error log. The http_header_filter will find this
222 bucket, and output the error text, and then return
223 AP_FILTER_ERROR, which informs the server that the error web page
224 has already been sent. [Ryan Bloom]
226 *) If we get an error, then we should remove all filters except for
227 those critical to serving a web page. This fixes a bug, where
228 error pages were going through the byterange filter, even though
229 that made no sense. [Ryan Bloom]
231 *) Relax the syntax checking of Host: headers in order to support
232 iDNS. PR#6635 [Tony Finch]
234 *) Cleanup the byterange filter to use the apr_brigade_partition
235 and apr_bucket_copy functions. This removes a lot of very messy
236 code, and hopefully makes this filter more stable.
239 *) Remove AddModule and ClearModuleList directives. Both of these
240 directives were used to ensure that modules could be enabled
241 in the correct order. That requirement is now gone, because
242 we use hooks to ensure that modules are in the correct order.
245 *) When SuExec is specified, we need to add it to the list of
246 targets to be built. If we don't, then any changes to the
247 configuration won't affect SuExec, unless 'make suexec' is
248 specifically run. [Ryan Bloom]
250 *) Cleaned out open_file from mod_file_cache, as apr now accepts
251 the APR_XTHREAD argument to open a file for consumption by
252 parallel threads on win32. [William Rowe]
254 *) Correct a bug in determining when we follow symlinks. The code
255 expected a stat -1 result, not an apr_status_t positive error.
256 Also check if the APR_FINFO_USER fields are valid before we
257 follow the link. [William Rowe]
259 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
260 mpm_common.c. These functions are only valid on some platforms,
261 so they should not be in the main-line code. [Ryan Bloom]
263 *) Remove ap_chdir_file(). This function is not thread-safe,
264 and nobody is currently using it. [Ryan Bloom]
266 *) Do not try to run make depend if there are no .c files in the
267 current directory, doing so makes `make depend` fail.
270 *) Update highperformance.conf to work with either prefork or
271 pthreads mpms. [Greg Ames]
273 *) Stop checking to see if this is a pipelined request if we know
274 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
275 This keeps us from making an extra read call when serving a 1.0
276 request. [Ryan Bloom and Greg Stein]
278 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
279 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
280 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
282 *) Fix the RFC number mentioned when complaining about a missing
283 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
285 *) Fix an endless loop in ab which occurred when ab was posting
286 and the server dropped the connection unexpectedly.
289 *) Fix a segfault while handling request bodies in ap_http_filter().
290 This problem has been seen with mod_dav usage as well as with
291 requests where the body was just being discarded. [Jeff Trawick]
293 *) Some adjustment on the handling and automatic setting (via
294 hints.m4) of various compilation flags (eg: CFLAGS). Also,
295 add the capability to specify flags (NOTEST_CFLAGS and
296 NOTEST_LDFLAGS) which are used to compile Apache, but
297 not used during the configuration process. Useful for
298 flags like "-Werror". [Jim Jagielski]
300 *) Stop using environment variables to force debug mode or
301 no detach. We now use the -D command line argument to
302 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
303 [Greg Stein, Ryan Bloom]
305 *) Change handlers to use hooks. [Ben Laurie]
307 *) Stop returning copies of filenames from both apr_file_t and
308 apr_dir_t. We pstrdup the filenames that we store in the
309 actual structures, so we don't need to pstrdup the strings again.
312 *) mod_cgi: Fix some problems where the wrong error value was being
313 traced. [Jeff Trawick]
315 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
318 *) Add generic hooks. [Ben Laurie]
320 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
322 *) Fix a segfault caused by mod_ext_filter when the external filter
323 program does not exist. [Jeff Trawick]
325 *) Fix an output truncation error when on an HTTP >= 1.0 request an
326 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
327 was served through mod_charset_lite (or anything else that would
328 create a transient bucket in this size range). ap_bucket_make_heap()
329 silently failed (fixed), transient_setaside() discovered it, but
330 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
332 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
333 is that some browsers send extra lines at the end of POST requests, and
334 we don't want to delay sending data back to the user just because the
335 browser isn't well behaved. [Ryan Bloom]
337 *) Get SuEXEC working again. We can't send absolute paths to suExec
338 because it refuses to execute those programs. SuEXEC also wasn't
339 always recognizing configuration changes made using the autoconf
342 *) Allow the buildconf process to find the config.m4 files in the correct
343 order. Basically, we can now name config.m4 files as config\d\d.m4,
344 and we will sort them correctly when inserting them into the build
345 process. [Ryan Bloom]
347 *) Get mod_cgid to use apr calls for creating the actual CGI process.
348 This also allows mod_cgid to use ap_os_create_priviledged_process,
349 thus allowing for SuExec execution from mod_cgid. Currently, we do
350 not support everything that standard SuExec supports, but at least
351 it works minimally now. [Ryan Bloom]
353 *) Allow SuExec to be configured from the ./configure command line.
356 *) Update some of the docs in README and INSTALL to reflect some of
357 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
359 *) If we get EAGAIN returned from the call to apr_sendfile, then we
360 need to call sendfile again. This gets us serving large files
361 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
363 *) Get the support programs building cleanly again.
364 [Cliff Woolley <cliffwoolley@yahoo.com>]
366 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
367 current directory logic now backs up over bin/ to determine the
368 server root from the Apache.exe path.
370 *) Apache/Win32 now follows the standard conventions of mod_foo.so
371 loadable modules, dynamic libs are all named libfoo.dll, and the
372 makefile.win populates the include, lib and libexec directories.
374 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
375 Apache gets IPv6 listening sockets by default. Additionally, the
376 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
377 numeric address strings (e.g., "Listen [fe80::1]:8080").
380 *) Modify the install directory layout. Modules are now installed in
381 modules/. Shared libraries should be installed in libraries/, but
382 we don't have any of those on Unix yet. All install directories
383 are modifyable at configure time. [Ryan Bloom]
385 *) Install all header files in the same directory on Unix. [Ryan Bloom]
387 *) Get the functions in server/linked into the server, regardless of
388 which modules linked into the server. This uses the same hack
389 for Apache that we use for APR and apr-util to ensure all of the
390 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
391 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
392 the scripts a bit easier.
395 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
396 on the query, and remove IPv4 dependencies. [Jeff Trawick]
398 *) Get all of the auth modules to the point that they will install and
399 be loadable into the server. Our new build/install mechanism expects
400 that all modules will have a common name format. The auth modules
401 didn't use that format, so we didn't install them properly.
404 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
405 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
407 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
409 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
410 after the end of the response. [Ryan Bloom]
412 *) Get byterange requests working with responses that do not have a
413 content-length. Because of the way byterange requests work, we have to
414 have all of the data before we can actually do the byterange, so we
415 can compute the content-length in the byterange filter.
418 *) Get exe CGI's working again on Windows.
421 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
422 they keep track of whether or not their post config hook has been
423 called before. Instead of a static variable (which is replaced when
424 the DSO is loaded a second time), use userdata in the process pool.
427 Changes with Apache 2.0a9
429 *) Win32 now requires perl to complete the final install step for users
430 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
431 and installs the conf, htdocs and htdocs/manual directories.
434 *) Make mod_include use a hash table to associate directive tags with
435 functions. This allows modules to implement their own SSI tags easily.
436 The idea is simple enough, a module can insert it's own tag and function
437 combination into a hash table provided by mod_include. While mod_include
438 parses an SSI file, when it encounters a tag in the file, it does a
439 hash lookup to find the function that implements that tag, and passes
440 all of the relevant data to the function. That function is then
441 responsible for processing the tag and handing the remaining data back
442 to mod_include for further processing.
443 [Paul J. Reder <rederpj@raleigh.ibm.com>]
445 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
446 fewer parameters: the local and remote socket addresses were removed
447 from the parameter list because all required information is available
448 via the APR socket. [Jeff Trawick]
450 *) Distribution directory structure reorganized to reflect a
451 normal source distribution with external install targets.
454 *) The MPMs that need multiple segments of shared memory now create
455 two apr_shmem_t variables, one for each shared memory allocation.
456 the problem is that we can't determine how much memory will be required
457 for shared memory allocations once we try to allocate more than one
458 variable. The MM code automatically aligns the shared memory allocations,
459 so we end up needing to pad the amount of shared memory we want based
460 on how many variables will be allocated out of the shared memory segment.
461 It is just easier to create a second apr_shmem_t variable, and two
465 *) Cleanup the export list a bit. This creates a single unified list of
466 functions exported by APR. The export list is generated at configure
467 time, and that list is then used to generate the exports.c file.
468 Because of the way the export list is generated, we only export those
469 functions that are valid on the platform we are building on.
472 *) Enable logging the cookie with mod_log_config
473 [Sander van Zoest <sander@covalent.net>]
475 *) Fix a segfault in mod_info when it reaches the end of the configuration.
478 *) Added lib/aputil/ as a placeholder for utility functions which are not
479 specific to the Apache HTTP Server (but do not make sense with APR).
480 The first utility is "apu_dbm": a set of functions to work with DBM
481 files. This first version can be compiled for SDBM or GDBM databases.
484 *) Complete re-write of mod_include. This makes mod_include a filter that
485 uses buckets directly. This has now served the FAQ correctly.
486 [Paul Reder <rederpj@raleigh.ibm.com>]
488 *) Allow modules to specify the first filter in a sub_request when
489 making the sub_request. This keeps modules from having to change the
490 output_filter immediately after creating the sub-request, and therefore
491 skip the sub_req_output_filter. [Ryan Bloom]
493 *) Update ab to accept URLs with IPv6 literal address strings (in the
494 format described in RFC 2732), and to build Host header fields in
495 the same format. This allows IPv6 literal address strings to be
496 used with ab. This support has been tested against Apache 1.3 with
497 the KAME patch, but Apache 2.0 does not yet work with this format
498 of the Host header field. [Jeff Trawick]
500 *) Accomodate an out-of-space condition in the piped logs and the
501 rotatelogs.c code, and no longer churn log processes for this
502 condition. [Victor J. Orlikowski]
504 *) Add support for partial writes with apr_sendfile() to core_output_filter.
507 Changes with Apache 2.0a8
509 *) Add a directive to mod_mime so that filters can be associated with
513 *) Get multi-views working again. We were setting the path_info
514 field incorrectly if we couldn't find the specified file.
517 *) Fix 304 processing. The core should never try to send the headers
518 down the filter stack. Always, just setup the table in the request
519 record, and let the header filter convert it to data that is ready
523 *) More fixes for the proxy. There are still bugs in the proxy code,
524 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
528 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
531 *) APR: Add new apr_getopt_long function to handle long options.
532 [B. W. Fitzpatrick <fitz@red-bean.com>]
534 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
535 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
536 hostname resolution/address string parsing and building
537 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
538 of one of the apr_sockaddr_t structures for a socket. Change
539 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
541 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
542 I have proxied pages with it, cleanup will commence soon.
545 *) Make the proxy work with filters. This isn't perfect, because we
546 aren't dealing with the headers properly. [Ryan Bloom]
548 *) Do not send a content-length iff the C-L is 0 and this is a head
549 request. [Ryan Bloom]
551 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
552 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
554 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
556 *) Get the default_handler to stop trying to deal with HEAD requests.
557 The idea is to let the content-length filter compute the C-L before
558 we try to send the data. If we can get the C-L correctly, then we
559 should send it in the HEAD response.
562 *) The Header filter can now determine if a body should be sent based
563 on r->header_only. The general idea of this is that if we delay
564 deciding to send the body, then we might be able to compute the
565 content-length correctly, which will help caching proxies to cache
566 our data better. Any handler that doesn't want to try to compute
567 the content-length can just send an EOS bucket without data and
568 everything will just work.
571 *) Add the referer to the error log if one is available.
572 [Markus Gyger <mgyger@itr.ch>]
574 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
575 change, the root of the configuration tree has been exposed to modules
577 [Ryan Morgan <rmorgan@covalent.net>]
579 *) Get the core_output_filter to use the bucket interface directly.
580 This keeps us from calling the content-length filter multiple times
581 for a simple static request.
584 *) We are sending the content-type correctly now.
585 [Ryan Bloom and Will Rowe]
587 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
588 a bogus bytes-sent value when the only thing being sent was trailers
589 and writev() returned an error (or EAGAIN). [Jeff Trawick]
591 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
592 hints file to determine which platforms define
593 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
596 *) APR: add apr_get_home_directory() [Jeff Trawick]
598 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
600 *) Not all platforms have INADDR_NONE defined by default. Apache
601 used to make this check and define INADDR_NONE if appropriate,
602 but APR needs the check too, and I suspect other applications will
603 as well. APR now defines APR_INADDR_NONE, which is always a valid
604 value on all platforms.
605 [Branko Èibej <brane@xbc.nu>]
607 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
608 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
610 *) Relax the syntax checking of Host: headers in order to support
611 iDNS. PR#6635 [Tony Finch]
613 *) When reading from file buckets we convert to an MMAP if it makes
614 sense. This also simplifies the default handler because the
615 default handler no longer needs to try to create MMAPs.
618 *) BUFF has been removed from the main server. The BUFF code will remain
619 in the code until it has been purged from the proxy module as well.
622 *) Byteranges have been completely re-written to be a filter. This
623 has been tested, and I believe it is working correctly, but it could
624 doesn't work for the Adobe Acrobat plug-in. The output almost matches
625 the output from 1.3, the only difference being that 1.3 includes
626 a content-length in the response, and this does not.
629 *) APR read/write functions and bucket read functions now operate
630 on unsigned integers, instead of signed ones. It doesn't make
631 any sense to use signed ints, because we return the error codes,
632 so if we have an error we should report 0 bytes read or written.
635 *) Always compute the content length, whether it is sent or not.
636 The reason for this, is that it allows us to correctly report
637 the bytes_sent when logging the request. This also simplifies
638 content-length filter a bit, and fixes the actual byte-reporing
639 code in mod_log_config.c
642 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
643 it says, because it was only used by EOS and FLUSH buckets. Since
644 neither of those are required at the end of a brigade, this was
645 really signifying FLUSH_THE_DATA, but that can be determined better
646 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
647 buckets now return a length of 0, which is actually the amount of data
648 read, so they make more sense.
651 *) Allow the core_output_filter to save some data past the end of a
652 request. If we get an EOS bucket, we only send the data if it
653 makes sense to send it. This allows us to pipeline request
654 responses. As a part of this, we also need to allocate mmap
655 buckets out of the connection pool, not the request pool. This
656 allows the mmap to outlive the request.
659 *) Make blocking and non-blocking bucket reads work correctly for
660 sockets and pipes. These are the only bucket types that should
661 have non-blocking reads, because the other bucket types should
662 ALWAYS be able to return something immediately.
665 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
666 server, but use Ctrl+Break to initiate a graceful restart
667 instead of duplicating behavior. [John Sterling]
669 *) Patch mod_autoindex to set the Last-Modified header based on
670 the directory's mtime, and add the ETag header. [William Rowe]
672 *) Merge the 1.3 patch to add support for logging query string in
673 such a way that "%m %U%q %H" is the same as "%r".
676 *) Port three log methods from mod_log_config 1.3 to 2.0:
677 CLF compliant '-' byte count, method and protocol.
680 *) Add a new LogFormat directive, %c, that will log connection
681 status at the end of the response as follows:
682 'X' - connection aborted before the response completed.
683 '+' - connection may be kept-alive by the server.
684 '-' - connection will be closed by the server.
687 *) Expand APR for WinNT to fully accept and return utf-8 encoded
688 Unicode file names and paths for Win32, and tag the Content-Type
689 from mod_autoindex to reflect that charset if the the feature
690 macro APR_HAS_UNICODE_FS is true. [William Rowe]
692 *) Compute the content length (and add appropriate header field) for
693 the response when no content length is available and we can't use
694 chunked encoding. [Jeff Trawick]
696 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
697 so that content input filters get dechunked data when using
698 the default handler. Also removed REQUEST_CHUNKED_PASS.
701 *) Add mod_ext_filter as an experimental module. This module allows
702 the administrator to use external programs as filters. Currently,
703 only filtering of output is supported. [Jeff Trawick]
705 *) Most Apache functions work on EBCDIC machines again, as protocol
706 data is now translated (again). [Jeff Trawick]
708 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
709 the EBCDIC support. They are noops on ASCII machines, so this
710 type of translation doesn't have to be surrounded by #ifdef
711 CHARSET_EBCDIC. [Jeff Trawick]
713 *) Fix mod_include. tag commands work again, and the server will
714 send the FAQ again. This also allows mod_include to set aside
715 buckets that include partial buckets.
716 [Ryan Bloom and David Reid]
718 *) Add suexec support back. [Manoj Kasichainula]
720 *) Lingering close now uses the socket directly instead of using
721 BUFF. This has been tested, but since all we can tell is that it
722 doesn't fail, this needs to be really hacked on.
725 *) Allow filters to modify headers and have those headers be sent to
726 the client. The idea is that we have an http_header filter that
727 actually sends the headers to the network. This removes the need
728 for the BUFF to send headers.
731 *) Charset translation: mod_charset_lite handles translation of
732 request bodies. Get rid of the xlate version of ap_md5_digest()
733 since we don't compute digests of filtered (e.g., translated)
734 response bodies this way anymore. (Note that we don't do it at
735 all at the present; somebody needs to write a filter to do so.)
738 *) Input filters and ap_get_brigade() now have a input mode parameter
739 (blocking, non-blocking, peek) instead of a length parameter.
742 *) Update the mime.types file to the registered media types as
743 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
746 *) Namespace protect some macros declared in ap_config.h
749 *) Support HTTP header line folding with input filtering.
752 *) Mod_include works again. This should still be re-written, but at
753 least now we can serve an SHTML page again.
756 *) Begin to remove BUFF from the core. Currently, we keep a pointer
757 to both the BUFF and the socket in the conn_rec. Functions that
758 want to use the BUFF can, functions that want to use the socket,
759 can. They point to the same place.
762 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
763 [Tomas "Ögren" <stric@ing.umu.se>]
765 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
766 associated pool goes away. (APR pipes on OS/2 were already had this
767 logic.) This resolvs a fatal file descriptor leak with CGIs.
770 *) The final line of the config file was not being read if there was
771 no \n at the end of it. This was caused by apr_fgets returning
772 APR_EOF even though we had read valid data. This is solved by
773 making cfg_getline check the buff that was returned from apr_fgets.
774 If apr_fgets return APR_EOF, but there was data in the buf, then we
775 return the buf, otherwise we return NULL.
778 *) Piped logs work again in the 2.0 series.
781 *) Restore functionality broken by the mod_rewrite security fix:
782 rewrite map lookup keys and default values are now expanded
783 so that the lookup can depend on the requested URI etc.
784 PR #6671 [Tony Finch]
786 *) Tighten up the syntax checking of Host: headers to fix a
787 security bug in some mass virtual hosting configurations
788 that can allow a remote attacker to retrieve some files
789 on the system that should be inaccessible. [Tony Finch]
791 *) Add a pool bucket type. This bucket is used for data allocated out
792 of a pool. If the pool is cleaned before the bucket is destroyed, then
793 the data is converted to a heap bucket, allowing it to survive the
797 *) Add a flush bucket. This allows modules to signal that the filters
798 should all flush whatever data they currently have. There is no way
799 to actually force them to do this, so if a filter ignores this bucket,
800 that's life, but at least we can try with this.
803 *) Add an output filter for sub-requests. This filter just strips the
804 EOS bucket so that we don't confuse the main request's core output
805 filter by sending multiple EOS buckets. This change also makes sub
806 requests start to send EOS buckets when they are finished.
809 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
810 makes ap_bucket_destroy a return void, which is okay because it
811 used to always return APR_SUCCESS, and nobody ever checked its
813 [Cliff Woolley <cliffwoolley@yahoo.com>]
815 *) Remove the index into the bucket-type table from the buckets
816 structure. This has now been replaced with a pointer to the
817 bucket_type. Also add some macros to test the bucket-type.
820 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
821 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
822 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
823 All _VAR_ flavors changes to _DATA to be absolutely clear.
826 *) Add support for /, //, //servername and //server/sharename
827 parsing of <Directory> blocks under Win32 and OS2.
828 [Tim Costello, William Rowe, Brian Harvard]
830 *) Remove the function pointers from the ap_bucket type. They have been
831 replaced with a global table. Modules are allowed to register bucket
832 types and use then use those buckets.
835 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
836 once we finish writing the request body to the cgi child process;
837 otherwise, the client doesn't hit EOF on stdin. Small request bodies
838 worked without this change (for reasons I don't understand), but large
839 ones didn't. [Jeff Trawick]
841 *) Remove file bucket specific information from the ap_bucket type.
842 This has been moved to a file_bucket specific type that hangs off
843 the data pointer in the ap_bucket type.
846 *) Input filtering now has a third argument. This is the amount of data
847 to read from lower filters. This argument can be -1, 0, or a positive
848 number. -1 means give me all the data you have, I'll deal with it and
849 let you know if I need more. 0 means give me one line and one line
850 only. A positive number means I want no more than this much data.
852 Currently, only 0 and a positive number are implemented. This allows
853 us to remove the remaining field from the conn_rec structure, which
857 *) Big cleanup of the input filtering. The goal is that http_filter
858 understands two conditions, headers and body. It knows where it is
859 based on c->remaining. If c->remaining is 0, then we are in headers,
860 and http_filter returns a line at a time. If it is not 0, then we are
861 in body, and http_filter returns raw data, but only up to c->remaining
862 bytes. It can return less, but never more.
863 [Greg Ames, Ryan Bloom, Jeff Trawick]
865 *) mod_cgi: Write all of the request body to the child, not just what
866 the kernel would accept on the first write. [Jeff Trawick]
868 *) Back out the change that moved the brigade from the core_output_filters
869 ctx to the conn_rec. Since all requests over a given connection
870 go through the same core_output_filter, the ctx pointer has the
874 *) Fix another bug in the send_the_file() read/write loop. A partial
875 send by apr_send would cause unsent data in the read buffer to
876 get clobbered. Complete making send_the_file handle partial
877 writes to the network.
880 *) Fix a couple of type fixes to allow compilation on AIX again
881 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
883 *) Fix bug in send_the_file() which causes offset to be ignored
884 if there are no headers to send.
887 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
888 filter. Useful for supporting Windows 9* with a binary
889 compiled on Windows NT.
892 Changes with Apache 2.0a7
894 *) Reimplement core_output_filter to buffer/save bucket brigades
895 across multiple calls to the core_filter. The brigade will be
896 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
897 thresholds are hit or the EOS bucket is received.
900 *) Create experimental filter (buffer_filter) that coalesces bytes
901 into one large buffer before invoking the next filter in the
902 chain. This filter is particularly useful with the current
903 implementation of mod_autoindex when it inserted above the
904 chunk_filter. mod_autoindex generates a lot of brigades that
905 containing buckets holding just a few bytes each. The
906 buffer_filter coalesces these buckets into a single large bucket.
909 *) Add apr_sendfile() support into the core_output_filter.
912 *) Add apr_sendv() support into the core_output_filter.
915 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
916 [Mike Abbott <mja@sgi.com>]
918 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
919 make much sense, because Apache uses buckets instead of BUFFs now.
922 *) send_the_file now falls back to a read/write loop on platforms that
923 do not have sendfile.
924 [Ryan Bloom and Brian Havard]
926 *) Install apachectl correctly, and substitute the proper values so
927 that it works again. [Ryan Bloom]
929 *) Better(??) handle platforms that lack sendfile().
932 *) APR now has UUID generation/formatting/parsing support.
935 *) Begin the http_filter. This is an input filter that understands
936 the absolute basic amount required to parse an HTTP Request. The
937 goal is to be able to split headers from request body before passing
938 the data back to the other filters.
941 *) Bring forward from 1.3.13 the config directory implementation
944 *) install apxs if it is created
947 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
948 conversions. [William Rowe]
950 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
951 ap_add_output_filter(). [Jeff Trawick]
953 *) Multiple build and configuration fixes
956 -add datadir and localstatedir substitutions
958 -fix logfilename misspelling
959 -fix evaluation of installation dir variables and
960 -replace $foobar by $(foobar) to be usefull in the makefile
964 -add rules for cross-compiling in rules.mk. Okay, rule to check for
965 $CC_FOR_BUILD is still missing
966 -use CHECK_TOOL instead of CHECK_PROG for ranlib
967 -add missing "AR=@AR@" to severaly Makefile.in's
968 -cache result for "struct rlimit"
969 -compile all helper programs with native and cross compiler
970 and use the native version to generate header file
971 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
973 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
975 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
977 *) Fix a bug where a client which only sends \n to delimit header
978 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
979 message. Start working on ebcdic co-existance with input
981 [William Rowe, Greg Ames]
983 *) If mod_so is enabled in the server always create libexec, even
984 if there are no modules installed in this directory. This is a
985 requirement for APXS to work correctly.
988 *) Connection oriented output filters are now stored in the
989 conn_rec instead of the request_rec. This allows us to add the
990 output filter in the pre-connection phase instead of the
991 post_read_request phase, which keeps us from trying to write an
992 error page before we have a filter to write to the network.
993 [Ryan Bloom, Jeff Trawick, and Greg Ames]
995 *) Cleaning up an mmap bucket no longer deletes the mmap. An
996 mmap can be used across multiple buckets (default_handler with
997 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
998 the mmap itself can't be associated with the bucket.
1001 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
1004 *) Radical surgery to improve mod_isapi support under Win32.
1005 Includes a number of newer ServerSupportFunction calls, support
1006 for ReadClient (in order to retrieve POSTs greater than 48KB),
1007 and general bug fixes to more reliably load ISAPI .dll's and
1008 prevent leaking handle resources. Note: There are still
1009 discrepancies between IIS's and Apache's ServerVariables, and
1010 async calls are still not supported. Additional warnings are
1011 logged to facilitate debugging of unsupported ISAPI calls.
1014 *) Add input filtering to Apache. The basic idea for the input
1015 filters is the same as the ideas for output filters. The biggest
1016 difference is that instead of calling ap_pass_brigade, ap_get_brigade
1017 should be called, and the order of execution for the filter itself is
1018 different. When writing an output filter, a brigade is passed in,
1019 and filters operate directly on that brigade, when done, they call
1020 ap_pass_brigade. Input filters are the exact opposite. Because input
1021 is not a push operation, filters first call ap_get_brigade. When this
1022 function returns, the input filter will be left with a valid brigade.
1023 The input filter should then operate on the brigade, and return.
1026 *) Fix building on BSD/OS using its native make. The build system
1027 falls back to the BSD .include directive on that host platform.
1030 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
1031 SHA1 and plaintext password encodings. Make feature tests a
1032 bit more flexible. [William Rowe]
1034 *) Charset translation: mod_charset_lite handles output content
1035 translation in a filter. mod_charset_lite no longer ignores
1036 subrequests. A bunch of cruft related to BUFF's support for
1037 translating request and response bodies was removed.
1040 *) Move the addition of the CORE filter to the post_read_request
1041 hook in http_core.c. This removes the need to add the filter in
1042 multiple places and allows for an SSL module to be added much
1043 simpler. [Ryan Bloom]
1045 *) Fix a security problem that affects certain configurations of
1046 mod_rewrite. If the result of a RewriteRule is a filename that
1047 contains expansion specifiers, especially regexp backreferences
1048 $0..$9 and %0..%9, then it may be possible for an attacker to
1049 access any file on the web server. [Tony Finch]
1051 *) Fix a bug where errors that are detected during early request parsing
1052 don't produce visible HTTP error messages at the browser, because
1053 the core_filter wasn't present. [Greg Ames]
1055 *) Provide apr_socklen_t as a portability aid.
1056 [Victor J. Orlikowski]
1058 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
1059 as well as a comment arg to the add, adduser and update cmds.
1060 update allows the user to clear or preserve pw/groups/comment.
1061 Fixed a bug in dbmmanage that prevented the check option from
1062 parsing a password followed by :group... text. Corrected the
1063 seed calcualation for Win32 systems, and added -lsdbm support.
1066 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
1069 *) Avoid a segfault when parsing .htaccess files. An
1070 uninitialized tree pointer was passed to ap_build_config().
1073 *) Change the way that inet_addr & inet_network are checked for
1074 in APR's configure process to allow BeOS BONE to correctly
1075 find them. With this change BeOS BONE now builds from source
1076 with no problems. [David Reid]
1078 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
1079 the end of the parameters to execve() was stored in the wrong
1080 location, overlaying the storage beyond the newargs[] array and
1081 also passing uninitialized storage to execve(), which would
1082 sometimes fail with EFAULT. [Jeff Trawick]
1084 *) Fix a bug parsing configuration file containers. With a sequence
1085 like this in the config file
1087 <IfModule mod_kilroy.c>
1090 <IfModule mod_lovejoy.c>
1095 the second container would be terminated at the blank line due to
1096 sediment in the buffer from reading the prior </IfModule> and an
1097 error message would be generated for the real </IfModule> for the
1098 second container. Also due to this problem, any two characters
1099 could be used for "</" in the close of a container.
1102 *) ap_add_filter prototype changed to remove the ctx pointer. The
1103 pointer still remains in the filter structure, but it can not be
1104 a part of the ap_add_filter prototype. The reason is that when
1105 the core uses AddFilter to add a filter to the stack it doesn't
1106 know how to allocate the ctx pointer, or even how much memory should
1107 be allocated. The filters will have to be responsible for allocating
1108 the ctx memory when they need it.
1111 *) Add an AddFilter directive. This directive takes a list of filters
1112 that should be activated for the requested resource.
1115 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
1116 some other platforms). [Jeff Trawick]
1118 *) Modify mod_include to be a filter. Currently, it has only been tested
1119 on actual files, but it should work for CGI scripts too.
1122 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
1123 writes. apr_flush() for Unix: handle interrupted writes.
1126 *) NameVirtualHost can now take "*" as an argument instead of
1127 an IP address. This allows you to create a purely name-based
1128 virtual hosting server that does not have any IP addresses in
1129 the configuration file and which ignores the local address
1130 of any connections. PR #5595, PR #4455 [Tony Finch]
1132 *) Fix some compile warnings in mod_mmap_static.c
1133 [Mike Abbott <mja@sgi.com>]
1135 *) Fix chunking problem with CGI scripts. The general problem was that
1136 the CGI modules were adding an EOS bucket and then the core added an
1137 EOS bucket. The chunking filter finalizes the chunked response when it
1138 encounters an EOS bucket. Because two EOS buckets were sent, we
1139 finalized the response twice. The fix is to make sure we only send one
1140 EOS, by utilizing a flag in the request_rec.
1143 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
1144 and Win32. Previously, the first read from an apr_file_t set up via
1145 apr_put_os_file() would return a '\0'. [Jeff Trawick]
1147 *) Mod_cgid now creates a single element bucket brigade, with a pipe
1148 bucket, instead of using BUFF's and ap_r*.
1151 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
1152 [Mike Abbott <mja@sgi.com>]
1154 *) Remove ap_bopenf from buff code. This required modifying the file_cache
1155 code to use APR file's directly instead of going through BUFFs.
1158 *) Fix compile break on some platforms for mod_mime_magic.c
1159 [John K. Sterling <sterling@covalent.net>]
1161 *) Fix merging of AddDefaultCharset directive.
1162 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
1164 *) Minor revamp of the rlimit sections of code. We now test
1165 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
1166 is now "available" even if the platform doesn't support
1167 the rlimit family (it's just a noop though). [Jim Jagielski]
1169 *) Migrate the pre-selection of which MPM to use for specific
1170 platforms to hints.m4, which contains (or should contain)
1171 all platform specific "hints". [Jim Jagielski]
1173 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
1176 *) Add tables with non-string/binary values to APR.
1179 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
1182 *) Update PCRE to version 3.2. [Ryan Bloom]
1184 *) Change the way buckets' destroy functions are called so that
1185 they can be more directly used when changing the type of a
1186 bucket in place. [Tony Finch]
1188 *) Add generic support for reference-counting the resources used by
1189 buckets, and alter the HEAP and MMAP buckets to use it. Change
1190 the way buckets are initialised to support changing the type of
1191 buckets in place, and use it when setting aside TRANSIENT buckets.
1192 Change the implementation of TRANSIENT buckets so that it can be
1193 mostly shared with IMMORTAL buckets, which are now implemented.
1196 Changes with Apache 2.0a6
1198 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
1200 *) Add a chunking filter to Apache. This brings us one step closer
1201 to removing BUFF. [Ryan Bloom]
1203 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
1204 added to the stack is the last filter to be called. [Ryan Bloom]
1206 *) Apache 2.0 has been completely documented using Scandoc. The
1207 docs can be generated by running 'make docs'. [Ryan Bloom]
1209 *) Add filtered I/O to Apache. This is based on bucket brigades,
1210 Currently the buckets still use BUFF under the covers, but that
1211 should change quickly. The only currently written filter is the
1212 core filter which just calls ap_bwrite. [The Apache Group]
1214 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
1215 built with thread support. [Jeff Trawick]
1217 *) Abort configuration if --with-layout was specified and there's
1218 no layout definition file. [Ken Coar]
1220 *) Add support for '--with-port=n' option to configure. [Ken Coar]
1222 *) Add support for extension methods for the Allow response header
1223 field, and an API routine for accessing r->allowed and the
1224 list of extension methods in a unified manner. [Ken Coar]
1226 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
1227 [Rob Simonson <simo@us.ibm.com>]
1229 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
1230 APACHE_XLATE builds. [Jeff Trawick]
1232 *) A configuration file parsing problem was fixed. When the
1233 configuration file started with an IfModule/IfDefine container,
1234 only the last statement in the container would be retained.
1237 Changes with Apache 2.0a5
1239 *) Perchild is serving pages after passing them to different child
1240 processes. There are still a lot of bugs, but this does work. I
1241 have made requests against the same installation of Apache, and had
1242 different servers use different user IDs to serve the responses.
1243 This change moves to using socketpair instead of an AF_UNIX socket.
1246 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
1247 It can't seem to pass between child processes yet, but I think we
1248 are closer now than before. This moves us back to using Unix
1249 Domain Sockets. [Ryan Bloom]
1251 *) libapr functions and types renamed with apr_ prefix.
1252 #include "apr_compat.h" for 1.3.x backwards compat
1255 *) Fix problems with APR sockaddr handling on Win32. It didn't always
1256 return the right information on the local socket address.
1257 [Gregory Nicholls <gnicholls@level8.com>]
1259 *) ap_recv() on Win32: Set bytes-read to 0 on error.
1260 [Gregory Nicholls <gnicholls@level8.com>]
1262 *) Add an option to not detach from the controlling terminal without
1263 going into single process mode. This allows for much easier
1264 debugging of the process startup code. [Ryan Bloom]
1266 *) ab: don't use perror() to report the failure of an APR function.
1269 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
1270 scoreboard on graceful restarts.
1273 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
1274 An invalid ap_proc_t was passed to ap_create_process().
1277 *) Allow modules to register filters. Those filters are still
1278 never called, but this is a step in the right direction.
1279 [Ryan Bloom and Greg Stein]
1281 *) Register the mod_cgid daemon process for cleanup so that it is
1282 killed at termination if it does not die when the parent gets
1283 SIGTERM. This change is to fix occasional problems where the
1284 process stays around. Bugs in similar logic in mod_rewrite and
1285 mod_include were also fixed. [Jeff Trawick]
1287 *) Fix a bug in the time handling. Basically, we were imploding a time
1288 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
1289 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
1290 uses those two fields to adjust the time value. Because of the HTTP
1291 spec, both of those values can be zero'ed out safely. This fixes
1292 the bug correctly. [Ryan Bloom]
1294 *) Fix a couple of place in the Windows code where the wrong error
1295 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
1297 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
1299 *) Added the APR_EOL_STR macro for platform dependent differences in
1300 logfiles and other raw text (such as all APR files). Fixes logfiles
1301 not terminated with cr/lf sequences in Win32. [William Rowe]
1303 *) Move all strings functions in APR to src/lib/apr/strings and create
1304 apr_strings.h for the prototypes. [Ryan Bloom]
1306 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
1307 to repeat the syscall until we stop getting EINTR. I noticed a
1308 related problem at termination (SIGTERM) on FreeBSD when using
1309 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
1310 implementation work properly with child init. Previously, ap_lock()
1311 was essentially a no-op because all children were using different
1312 locks and thus nobody ever blocked. [Jeff Trawick]
1314 *) The htdocs/ tree has been moved out of the CVS source tree into
1315 a separate area for easier development. This has NO EFFECT on
1316 end-users or Apache installations. [Ken Coar]
1318 *) Integrate the mod_dav module for WebDAV protocol handling. This
1319 adds the dav and dav_fs modules, the SDBM library, and additional
1320 XML handling utilities. [Greg Stein]
1322 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
1325 *) Update the lib/expat-lite/ library (bring forward changes from
1326 the Apache 1.3 repository). [Greg Stein]
1328 *) If sizeof(long long) == sizeof(long), then prefer long in APR
1329 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
1331 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
1332 machines where sendfile is detected, but nobody has written ap_sendfile.
1333 [Dave Hill <ddhill@zk3.dec.com>]
1335 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
1337 *) ab would start up more connections than needed, then quit when the
1338 desired number were finished. Also fixed a logic error involving
1339 ab keepalives. [Victor J. Orlikowski]
1341 *) WinNT: Implement non-blocking pipes with timeouts to communicate
1342 with CGIs. Apache 2.0a4 had non-blocking pipes but without
1343 timeouts (i.e, if a timeout was specified, the pipe reverted to
1344 a full blocking pipe). Now the behaviour is more in line with
1345 Unix non-blocking pipes.
1348 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
1349 cache open file handles along with accept socket reuse enables
1350 Apache 2.0 to serve non-keepalive requests for static files at
1351 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
1352 and Apache 2.0 will serve almost 1200 rps on my system).
1355 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
1356 supports two config directives, mmapfile (same behavious as
1357 mod_mmap_static) and cachefile. Use the cachefile directive
1358 to cache open file handles. This directive only works on systems
1359 that have implemented the ap_sendfile API. cachefile works today
1360 on Windows NT, but has not been tested on any flavors of Unix.
1363 *) Cleanup the configuration. With the last few changes the
1364 configuration process automatically:
1365 inherits information about how to build from APR. Allowing
1366 APR to inform Apache that it should or should not use -ldl
1368 Detects which mod_cgi should be used mod_cgi or mod_cgid,
1369 based on the threading model
1371 Apache calls APR's configure process before finishing it's
1372 configuration processing, allowing for more information flow
1377 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
1378 with non-zero argument makes the socket non-blocking. BeOS and
1379 OS/2 already worked this way. [Jeff Trawick]
1381 *) ap_close() now calls ap_flush() for buffered files, so write
1382 operations work a whole lot better on buffered files.
1385 *) Fix error messages issued from MPMs which explain where to change
1386 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
1389 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
1390 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
1391 now the way that the blocking state of a pipe is manipulated.
1392 ap_block_pipe() is gone. [Jeff Trawick]
1394 *) Correct the problem where the only local host name that the IP stack
1395 can discover are 'undotted' private names. If no fully qualified
1396 domain name can be identified, the default ServerName will be set to
1397 the machine's IP address string. A warning is always provided if the
1398 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
1400 *) Repair problems with config file processing which caused segfault
1401 at init when virtual hosts were defined and which caused ServerName to
1402 be ignored when there was no valid DNS setup. [Jeff Trawick]
1404 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
1406 *) Add ap_sendfile implementation for AIX
1407 [Victor J. Orlikowski]
1409 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
1410 apr_network_io.h, and apr_thread_proc.h.
1411 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
1413 *) Bring the allocation and pool debugging code back into a working
1414 state. This will need to be tested as so far it's only been used on
1417 *) Change configuration command setup to be properly typesafe when in
1418 maintainer mode. Note that this requires a compiler that can initialise
1419 unions. [Ben Laurie]
1421 *) Turn on buffering for config file reads. Part of this was to
1422 repair buffered I/O support in Unix and implement buffered
1423 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
1425 *) Win32: Fix problem where UTC offset was not being set correctly
1426 in the access log. Problem reported on news group by Jerry Baker.
1429 *) Fix segfault when reporting this type of syntax error:
1430 "</container> without matching <container> section", where
1431 container is VirtualHost or Directory or whatever.
1434 *) Prevent the source code for CGIs from being revealed when using
1435 mod_vhost_alias and the CGI directory is under the document root
1436 and a user makes a request like http://www.example.com//cgi-bin/cgi
1437 as reported in <news:960999105.344321@ernani.logica.co.uk>
1440 *) Add support for the new Beos NetwOrking Environment (BONE)
1443 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
1444 final input char is incomplete; ap_bwrite_xlate() now handles
1445 incomplete final input chars. [Jeff Trawick]
1447 *) Yet another update to saferead/halfduplex stuff -- need to ensure
1448 that a bhalfduplex call occurs before logging or else DNS and
1449 such can delay the last packet of the response. [Dean Gaudet]
1451 *) Some syscall reduction in APR on unix -- don't seek when setting
1452 up an mmap; and don't fcntl() more than once per socket.
1455 *) When mod_cgid is started as root, the cgi daemon now switches
1456 to the configured User/Group (like other httpd processes)
1457 instead of continuing as root. [Jeff Trawick]
1459 *) The prefork MPM now uses an APR lock for the accept() mutex.
1460 It has not been getting a lock at all recently. httpd -V now
1461 displays APR's selection of the lock mechanism instead of the
1462 symbols previously respected by prefork. [Jeff Trawick]
1464 *) Change the mmap() feature test to check only for existence.
1465 The previous check required features not used by Apache.
1468 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
1469 sometimes mangled. The len parm to accept() was not
1470 initialized, leading sometimes to an endless loop of failed
1471 accept() calls on OS/390 and anywhere else that failed the call
1472 if the len was negative. Use <sys/un.h> for struct sockaddr_un
1473 instead of declaring it ourselves to fix a compilation problem
1474 on Solaris. [Jeff Trawick]
1476 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
1478 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
1480 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
1482 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
1483 initialization if ALLOC_DEBUG is defined; no known symptom
1484 otherwise. [Jeff Trawick]
1486 *) Fix typo in configure script when checking for mod_so. bash
1487 doesn't seem to have a problem but /bin/sh on Solaris does.
1488 Symptom: "./configure: test: unknown operator =="
1491 *) Rebind the Win32 NT and 9x services control into the MPM.
1492 All console, WinNT SCM and Win9x pseudo-service control code is
1493 now wrapped within the WinNT MPM.
1496 *) Make a copy of getenv("PATH") before storing for later use. Some
1497 getenv() implementations use the same storage for successive calls.
1498 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
1500 *) Server Tokens work in 2.0 again. This also propogates the change
1501 to allow just the product name in the server string using
1505 Changes with Apache 2.0a4
1507 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
1508 won't need to call it. [Greg Ames, Jeff Trawick]
1510 *) Move pre_config hook call to between configuration read and config
1511 tree walk. This allows all modules to implement pre_config hooks
1512 and know that they will be called at an appropriate time.
1515 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
1518 *) Add pre-config hooks back to all modules.
1521 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
1522 ContentDigest enabled and we can't/don't mmap the file.
1525 *) We now report the correct line number for syntax errors in config
1526 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
1528 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
1529 related bugs, and changed shmem/locking to use apr API. Shared-mem
1530 is currently disabled, however, because of problems with graceful
1531 restarts. [Ronald Tschalär]
1533 *) Fix corruption of IFS variable in --with-module= handling.
1534 Depending on the user's shell or customization thereof, there
1535 would be errors generating ap_config_auto.h later in the configure
1536 procedure. [Jeff Trawick]
1538 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
1539 isn't used (as in 1.3), except that on Unix it is now logged via
1540 ap_log_rerror() instead of by the child having STDERR_FILENO refer
1541 to the error log. [Greg Ames, Jeff Trawick]
1543 *) Add '-D' argument processing for run time configuration defines.
1546 *) Organize http_main.c as independent code, such that no code or
1547 global data is exported from it. WIN32 will dynamically link it
1548 to the server core, so this will prevent mutual dependency.
1551 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
1552 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
1555 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
1556 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
1558 *) Add mod_charset_lite for configuring character set translation.
1561 *) Add '-n' option to htpasswd to make it print its user:pw record
1562 on stdout rather than having to frob a text file. [Ken Coar]
1564 *) Fix saferead. Basically, we flush the output buffer if a read on the
1568 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
1569 a conversion is single-byte only. [Jeff Trawick]
1571 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
1572 the BeOS 5.0 documentation says that shutdown doesn't work yet.
1575 *) Fix some minor errors where pid was being manipulated as an int
1576 instead of the portable pid_t. [Roy Fielding]
1578 *) Fix some error log prints that were printing the pointer to a
1579 structure rather than the pid within the structure.
1580 [Jeff Trawick, Roy Fielding]
1582 *) ab: Fix a command-line processing bug; track bad headers in
1583 err_response; support reading headers up to 2K.
1584 [Ask Bjoern Hansen <ask@valueclick.com>]
1586 *) Fix ap_resolve_env() so that it handles new function added in a prior
1587 alpha (see "Added the capability to do ${ENVVAR} constructs in the
1588 config file.") as well as the constructs used by mod_rewrite.
1589 [Paul Reder <rederpj@raleigh.ibm.com>]
1591 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
1593 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
1594 APR to perform translation, instead of accessing the hard-coded tables
1595 in 1.3's ebcdic.c. [Jeff Trawick]
1597 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
1600 *) Add the ability to hook into the config file reading phase. Basically
1601 if a directive is specified EXEC_ON_READ, then when that directive is
1602 read from the config file, the assocaited function is executed. This
1603 should only be used for those directives that must muck with HOW the
1604 server INTERPRETS the config. This should not be used for directives
1605 that re-order or replace items in the config tree. Those changes should
1606 be made in the pre-config step.
1609 *) Add mod_example to the build system.
1612 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
1613 byte character sets. [Jeff Trawick]
1615 *) Pick up various EBCDIC fixes from 1.3 (from Martin
1616 Kraemer and Oliver Reh originally according to the change log).
1619 *) Fix a couple of problems in RFC1413 support (controlled by the
1620 IdentityCheck directive). Apache did not build the request string
1621 properly and more importantly Apache would loop forever if the
1622 would-be ident server dropped the connection before sending a
1623 properly terminated response. [Jeff Trawick]
1625 *) apxs works in 2.0.
1628 *) Reliable piped logs work in 2.0.
1631 *) Introduce a hash table implementation into APR to be used for
1632 replacing tables and other random data structures in Apache.
1635 *) Add some more error reporting to htpasswd in the case of problems
1636 generating or accessing the temporary file. Also, pass in a
1637 buffer if the implementation knows how to use it (i.e., if L_tmpnam
1638 is defined). [Ken Coar]
1640 *) Configure creates config.nice now containing your configure
1641 options. Syntax: ./config.nice [--more-options]
1644 *) Fix various return code problems in APR on Win32. For most of
1645 these, APR was returning APR_EEXIST instead of GetLastError()/
1646 WSAGetLastError(). [Jeff Trawick]
1648 *) Make piped logs work again in version 2.0
1651 *) Add VPATH support to UNIX build system of Apache and APR.
1654 *) Fix ap_tokenize_to_argv to respect the const arguments that are
1658 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
1659 Patch submitted to author.
1662 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
1663 /sbin in PATH on FreeBSD (all submitted to rse previously)
1666 *) Fix building Pthread-based MPMs on OpenBSD
1667 [Sascha Schumann] PR#26
1669 *) Fix ap_readdir() problem on systems where d_name[] field in
1670 struct dirent is declared with only one byte. (This problem only
1671 affected multithreaded builds.) This caused a segfault during
1672 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
1673 least). [Jeff Trawick]
1675 *) Fix some make-portability problems on at least Tru64, Irix
1677 [Sascha Schumann] PR#18, PR#39
1679 *) Add ap_sigwait() to support old-style sigwait() on systems
1680 like OS/390 and UnixWare.
1683 *) Add POSIX-thread flags for more platforms.
1686 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
1687 (on Unix, at least) to handle resolver errors. Fix a bug in
1688 the definition of APR_ENOMEM so that ap_strerror() can spit
1689 out the correct error message for it.
1692 Changes with Apache 2.0a3
1694 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
1697 *) API: *HOOK* macros now have an AP_ prefix
1700 *) Win32: Eliminate redundant calls to initialize winsock.
1701 [Tim Costello <timcostello@ozemail.com.au>]
1703 *) Fix bugs initializing ungetchar for pipes.
1704 [Chia-liang Kao <clkao@CirX.ORG>]
1706 *) The ab program in the src/support directory is now portable using
1710 *) Support directory is being compiled when the server is built
1713 *) The configure option --with-program-name has been added to allow
1714 developers to rename the executable at configure time. This also
1715 changes the name of the config files to match the executable's name.
1718 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
1719 containing version numbers. [Martin Pool]
1721 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
1722 Unix; access_log and error_log now created with these perms; non-
1723 Unix is unaffected [Jeff Trawick]
1725 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
1726 Replaced more magic numbers with MD5_DIGESTSIZE.
1727 [William Rowe, Roy Fielding]
1729 *) Win32: Get mod_auth_digest compiling and added to the Windows
1730 build environment. Not tested and I'd be suprised if it
1731 actually works. [Bill Stoddard]
1733 *) Revamp the Win32 make environment. Makefiles have been removed and
1734 Apache.dsw created to bring together all the pieces. Create new file
1735 os/win32/BaseAddr.ref to define module base addresses (to prevent
1736 dll relocation at start-up).
1737 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
1739 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
1740 of the \015, \012, and \015\012 constants with macros.
1741 [Greg Ames <gregames@us.ibm.com>]
1743 *) Add ap_xlate_open() et al for translation of text between different
1744 character sets. The initial implementation requires iconv().
1747 *) More FAQs and answers from comp.infosystems.www.servers.unix.
1748 [Joshua Slive <slive@finance.commerce.ubc.ca>]
1750 *) CGI output is being timed out now.
1753 *) Fix the problem with dieing quietly. dupfile now takes a pool which
1754 is used by the new apr file. There is no reason to create a new file
1755 with the same lifetime as the original file.
1758 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
1759 module base addresses. This will help shooting seg faults
1760 in the field. [William Rowe <wrowe@lnd.com>]
1762 *) Update Apache on Windows documentation. Add new document
1763 describing how to compile Apache on Windows.
1764 [William Rowe <wrowe@lnd.com>]
1766 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
1767 microseconds instead of seconds. Some storage leaks and other
1768 minor bugs in related code were fixed. [Jeff Trawick]
1770 *) Win32: First cut at getting mod_isapi working under 2.0
1771 [William Rowe <wrowe@lnd.com>]
1773 *) First stab at getting mod_auth_digest working under 2.0
1774 quick change summary:
1775 - moved the random byte generation (ap_generate_random_bytes) into APR
1776 - now uses ap_time_t
1777 - compiles and runs on linux
1779 [Brian Martin <bmartin@penguincomputing.com>]
1781 *) Win32: Move the space stripping of physical service names
1782 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
1783 unresolved symbol. Add dependency checking to the
1784 CreateService call to ensure TCPIP and AFP (winsock) is started
1786 [William Rowe <wrowe@lnd.com>]
1788 *) Win32: Add code to perform latebinding on functions that may
1789 not exist on all levels of Windows where Apache runs. This
1790 is needed to allow Apache to start-up on Win95/98. All calls
1791 to non portable functions should be protected with
1792 ap_oslevel checks to prevent runtime segfaults.
1793 [William Rowe <wrowe@lnd.com>]
1795 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
1797 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
1799 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
1800 This addresses PR 1623. Still need to address timing out runaway
1801 CGI scripts. [Bill Stoddard]
1803 *) Win32: Make ap_stat Windows 95/98 friendly
1804 [William Rowe <wrowe@lnd.com>]
1806 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
1807 always fail. Need to initialise the dwOSVersionInfoSize member of the
1808 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
1811 The patch also enhances ap_get_oslevel (and the associated enum) to
1812 handle selected service packs for NT4, and adds recognition for
1813 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
1814 we can use ReadFileScatter and WriteFileGather in readwrite.c.
1815 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
1817 *) Get mod_rewrite building and running, and mod_status building for Win NT
1818 [Allan Edwards <ake@raleigh.ibm.com>]
1820 *) Patch to port mod_auth_db to the 2.0 api and also to support
1821 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
1822 2.7.7. It should work with version 1 as well but I haven't tested it.
1823 [Brian Martin <bmartin@penguincomputing.com>]
1825 *) Get APR DSO code working under Windows. Includes cross platform
1827 [Tim.Costello@BTFinancialgroup.com]
1829 *) Fix some of the Windows APR time functions.
1832 *) FAQ changes related to tidying up historical documents on the web site.
1833 [Joshua Slive <slive@finance.commerce.ubc.ca>]
1835 *) Move Windows DSO code into APR.
1838 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
1839 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
1840 at build time. At this point, the server will not compile on Windows because
1841 of the recent DSO commits. Fixing those next.
1842 [Bill Rowe & Bill Stoddard]
1844 *) Added error checking for file I/O APR routines.
1845 [Jon Travis <jtravis@covalent.net>]
1847 *) APR: Don't use the values of resolver error codes for the
1848 corresponding APR error codes. On Unix and Win32, return the
1849 proper APR error code after a resolver error. [Jeff Trawick]
1851 Changes with Apache 2.0a2
1853 *) Renamed the executable back to httpd on all platforms other
1857 *) Allow BeOS to survive restarts, log properly and a few
1858 small things it had problems with due to the way it setup
1859 users and groups. [David Reid]
1861 *) Get mod_rewrite working with APR locks
1862 [Paul Reder <rederpj@raleigh.ibm.com>]
1864 *) Actually remove the sempahore when the lock cleanup routine
1865 is called on BeOS. [David Reid]
1867 *) Clear hook registrations between reads of the config file.
1868 When DSOs are unloaded and re-loaded the old hook pointers may
1869 no longer be valid. This fix eliminates potential segfaults.
1870 [Allan Edwards <ake@raleigh.ibm.com>]
1872 *) Fix a problem with Sigfunc not being defined or bypassed
1873 if sigaction() wasn't found. [Jim Jagielski]
1875 *) Fix the locking mechanism on BSD variants. They now use fcntl
1876 locks. This allows the server to start and serve pages.
1879 *) First cut at getting the Win32 installer to work
1880 [William Rowe <wrowe@lnd.com>]
1882 *) Get htpasswd compiling under Windows
1883 [William Rowe <wrowe@lnd.com>]
1885 *) Change the log message for a bind() failure to show the
1886 interface and port number. [Jeff Trawick]
1888 *) Import the documentation from 1.3.12 and bring parts of it
1889 up-to-date with respect to the changes that have occurred
1893 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
1894 now logged correctly on BeOS.
1897 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
1898 Makefile.win includes the same user interface as the old
1900 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
1902 *) Win32 exec now uses COMSPEC environment string for command
1903 shell path resolution.
1904 [William Rowe <wrowe@lnd.com>] PR#3715
1906 *) Win32: ap_connect() was not returning correct error condition
1908 [Allen Prescott <allen@clanprescott.com>]
1910 *) Win32: ap_open() was broken on Win9x because an NT-specific
1911 flag was passed to CreateFile. ap_puts() added an unnecessary
1913 [Jeff Trawick <trawick@us.ibm.com>]
1915 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
1916 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
1917 confusing ee/et name and made all extensions language/dialect
1918 rather than country reflecting. Changed example files to
1919 explicit reflect the ISO charset and added a few common
1920 ones to the example config [dirkx]
1922 *) Extend external module capability. To use this, you call
1923 configure with --with-module=path/to/mod1,path/to/mod2,etc.
1926 *) Backported the various "default charset" fixes from 1.3.12,
1927 including the AddDefaultCharset directive. [Jim Jagielski]
1929 *) Added the capability to do ${ENVVAR} constructs in the
1930 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
1931 it does this on a line by line basis; i.e. if the envvar
1932 expands to something with spaces you have to protect it
1933 by adding quotes around it (Unless of course you expect it
1934 to contains more than one argument. Alternatively you
1935 can compile it on a per token basis; which is what people
1936 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
1937 hampers fancier hacks.
1938 [Dirk-Willem van Gulik]
1940 *) Changed the 'ErrorDocument' syntax in that it NO longer
1941 supports the asymetric
1943 ErrorDocument 301 "Some message
1945 Note the opening " quote, without a closing quote. It now
1946 has either the following syntaxes
1948 ErrorDocument XXX /local/uri
1949 ErrorDocument XXX http://valid/url
1950 ErrorDocument XXX "Some Message"
1952 The recognition heuristic is: if it has a space it
1953 is a message. If it has no spaces and starts with a /
1954 or is a valid URL then treat it that way. Otherwise it
1955 is assumed to be a message.
1957 This breaks backward compatibility but makes live a hell
1958 of a lot easier for GUI's and config file parsers.
1959 [Dirk-Willem van Gulik]
1961 *) Changed 'CacheNegotiatedDocs' from its present/not-present
1962 syntax into a 'on' or 'off' syntax. As it currently is the
1963 only non nesting token which uses NO_ARGS and thus is an
1964 absolute pain for any config interface automation. This
1965 breaks backward compatibility. [Dirk-Willem van Gulik]
1967 *) Add ability to add external modules to the build process. This is
1968 done with --with-module=/path/to/module. Modules can only be added
1969 as static modules at this point.
1972 Changes with Apache 2.0a1
1974 *) Fix FreeBSD 3.3 core dump.
1975 Basically, ap_initialize() needs to get called before
1976 create_process(), since create_process() passes op_on structure
1977 to semop() to get a lock, but op_on isn't initialized until
1978 ap_initialize() calls setup_lock(). Here is a slight
1979 rearrangement to main() which calls ap_initialize() earlier...
1980 [Jeff Trawick <trawick@us.ibm.com>]
1982 *) Enable Apache to use sendfile/TransmitFile API
1983 [Bill Stoddard, David Reid, Paul Reder]
1985 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
1989 *) Make file I/O and network I/O writev/sendv APIs consistent.
1990 Eliminate use of ap_iovec_t and use Posix struct iovec.
1991 Use seperate variable on ap_writev to set the number of iovecs
1992 passed in and number of bytes written.
1995 *) Adapt file iol to use APR functions. Replaced ap_open_file()
1996 with ap_create_file_iol(). ap_create_file_iol() requires that
1997 the file be opened prior to the call using ap_open().
2000 *) Port mod_include and mod_cgi to 2.0
2001 [Paul Reder, Bill Stoddard]
2003 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
2004 bytes_read/bytes_written is always valid (never -1). Plus
2005 some fixes to buff.c to correct problems introduced by the
2006 errno => ap_status_t changes a while back. Plus a fix to
2007 chunked encoding introduced right at the beginning of 2.0.
2010 *) Revamped UNIX build system to use autoconf and libtool.
2011 [Manoj Kasichainula, Sascha Schumann]
2013 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
2015 *) More rigorous checking of Host: headers to fix security problems
2016 with mass name-based virtual hosting (whether using mod_rewrite
2017 or mod_vhost_alias).
2018 [Ben Hyde, Tony Finch]
2020 *) Add back support for UseCanonicalName in <Directory> containers.
2021 [Manoj Kasichainula]
2023 *) Added APLOG_STARTUP log type. This allows us to write an error
2024 message without any of the date and time information. As a part
2025 of this change, I also removed all of the calls to fprintf(stderr
2026 and replaced them with calls to ap_log_error using APLOG_STARTUP
2027 writing to stderr is no longer portable, because we don't direct
2028 stderr to the error log on all platforms.
2031 *) Convert error logging functions to take errno as an argument.
2032 This makes our error logs more portable, because some Windows API's
2033 don't set errno. This change allows us to still output a valid
2034 message on all of our platforms.
2037 *) mod_mime_magic runs in 2.0-dev now.
2038 [Paul Reder <rederpj@raleigh.ibm.com>]
2040 *) sendfile has been added to APR.
2041 [John Zedlewski <zedlwski@Princeton.EDU>]
2043 *) buff.c has been converted to no longer use errno.
2044 [Manoj Kasichainula]
2046 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
2047 interface adaption to APR functions did it. [Martin Kraemer]
2049 *) Support DSOs properly on 32-bit HP-UX 11.0
2050 [Dilip Khandekar <dilip@cup.hp.com>]
2052 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
2053 [Ralf S. Engelschall]
2055 *) Cleaned APR build environment integration and bootstrap APR
2056 automatically for developers from src/Configure.
2057 [Ralf S. Engelschall]
2059 *) Fixed building of src/support/htpasswd.c
2060 [Ralf S. Engelschall]
2062 *) When generating the Location: header, mod_speling forgot
2063 to escape the spelling-fixed uri. (Forw-Port from 1.3)
2066 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
2068 *) Change all pools to APR contexts. This is the first step to
2069 incorporating APR into Apache. [Ryan Bloom]
2071 *) Move "handler not found" warning message to below the check
2072 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
2073 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
2075 *) Support line-continuation feature in config.option file and
2076 allow the loading of multiple option sections at once via
2077 ``--with-option=<section1>,<section2>,...''
2078 [Ralf S. Engelschall]
2080 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
2082 Changes with Apache MPM
2084 *) Use asynchronous AcceptEx() and a completion port to accept and
2085 dispatch connections to threads in Windows NT/2000.
2088 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
2091 *) Implement the APACI --with-option facility
2092 (per default used the config.option file).
2093 [Ralf S. Engelschall]
2095 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
2097 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
2098 Replace pre_connection module call with a register_hook call and
2099 implement pre_connection as a hook. The intent is that these hooks will
2100 be extended to allow Apache to be multi-protocol, and also to allow the
2101 calling order to be specified on a per-hook/per-module basis.
2104 *) Implement mpm_* methods as "modules". Each method gets its own
2105 subdir in src/modules (eg: src/modules/prefork). Selection
2106 of method uses Rule MPM_METHOD. [Jim Jagielski]
2108 *) Port the hybrid server from the apache-apr repository as
2109 mpm_mpmt_pthread. [Manoj Kasichainula]
2111 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
2112 amongst the unix MPMs.
2114 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
2115 signal handling for the new world order. [Dean Gaudet]
2117 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
2118 of alloc.c for now. [Dean Gaudet]
2120 *) Handle partial large writes correctly. [Ben Laurie]
2122 *) Eliminate conn_rec's pointer to server. All it knows is the base server
2123 based on IP/port. [Ben Laurie]
2125 *) Port a bunch of modules to the new module structure.
2126 ["Michael H. Voase" <mvoase@midcoast.com.au>]
2128 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
2130 *) Basic restructuring to introduce the MPM concept; includes various
2131 changes to the module API... better described by
2132 docs/initial_blurb.txt. [Dean Gaudet]
2134 Changes with Apache pthreads
2136 *) New buff option added: BO_TIMEOUT. It describes the timeout for
2137 buff operations (generally over a network).
2138 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
2140 *) Created http_accept abstraction. Added 4 new functions (not exported):
2141 init_accept(), begin_accepting_requests(), get_request(),
2142 stop_accepting_requests() [Bill Stoddard]
2144 *) Fix to ap_rprintf call that allows mod_info to work properly.
2145 [James Morris <jmorris@intercode.com.au>]
2147 *) user and ap_auth_type fields were moved from connection_rec to
2148 request_rec. [Ryan Bloom]
2150 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
2151 needed in a threaded server.
2153 *) Initial pthread implementation from from Dean's apache-nspr code.
2154 [Bill Stoddard, Ryan Bloom]
2157 Changes with Apache 1.3.9
2159 *) Remove bogus error message when a redirect doesn't set Location.
2160 Instead, use an empty string to avoid coredump if the error message
2161 was supposed to include a location. [Roy Fielding]
2163 *) Don't allow configure to include mod_auth_digest unless it is
2164 explicitly requested, even if the user asked for all modules.
2167 *) Translate module names to dll names for OS/2 so that they are no more
2168 than 8 characters long and have an extension of "dll" instead of "so".
2171 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
2172 Fix test-compile check to check for randbyte instead of trand32.
2173 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
2174 and tweak to make Amaya happier. [Ronald Tschalär]
2176 *) Ensure that the installed expat include files are world readable,
2177 just like the other header files. [Martin Kraemer]
2179 *) Fixed generated AddModule adjustments in APACI's `configure' script
2180 in order to allow (new) modules like mod_vhost_alias to be handled
2181 correctly (which was touched by the adjustments for mod_alias).
2182 [Ralf S. Engelschall]
2184 *) For binary builds, add -R flag to apachectl to work around the lack of
2185 an absolute path to the ./libexec directory where the libhttp.ep file
2186 is needed for SHARED_CORE architectures. [Randy Terbush]
2188 *) WIN32: Create the CGI script process as DETACHED. This may solve the
2189 problem observed by some Win95/98 users where they get CGI script
2190 output sent to the console. [Bill Stoddard]
2192 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
2193 routines are now called ap_base64* and are 'plain' (i.e., no
2194 pool access or anything clever). Inside util.c the routines acting
2195 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
2196 The oddly named ap_uuencode(), ap_uudecode() are kept around for
2197 now but deprecated. [dirkx]
2199 *) Clean up the base64 and SHA1 additions and make sure they are
2200 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
2201 files. [Roy Fielding]
2203 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
2204 checking. Allow compiling on VS 6.0. [Randy Terbush]
2206 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
2208 *) Use TestCompile to search for the truerand library (rather than blindly
2209 assuming its existence). If it is not found, complain (but do not
2210 exit - yet). [Martin Kraemer]
2212 *) We forgot to add the new exported function names to
2213 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
2215 *) Add description of -T command-line option to usage().
2216 [Ralf S. Engelschall]
2218 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
2219 searched only AFTER libap has been searched, because libap needs
2220 some symbols from libos. [Martin Kraemer]
2222 *) Fix conflict with original mod_digest related to the symbol of the
2223 module dispatch list (which has to be unique for DSO and follow the
2224 usual conventions for the installation procedure).
2225 [Ralf S. Engelschall]
2227 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
2228 for other platforms as well. [Martin Kraemer]
2230 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
2231 types by AP_LONG and replace reference to renamed variable 'ubuf'
2232 by 'buffer'. [Martin Kraemer]
2234 Changes with Apache 1.3.8 [not released]
2236 *) Flush the output buffer immediately after sending an error or redirect
2237 response, since the result may be needed by the client to abort a
2238 long data transfer or restart a series of pipelined requests.
2239 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
2241 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
2242 [Ian Turner <iant@sequent.com>] PR#4735
2244 *) Local struct mmap in http_core.c conflicted with system structure
2245 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
2247 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
2248 [Ronald Tschalär <ronald@innovation.ch>]
2250 *) Fix a memory leak where the module counts were getting messed
2251 up across restarts. [David Harris <dharris@drh.net>]
2253 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
2254 properly in mod_access.
2255 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
2257 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
2258 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
2260 *) PORT: Support for compaq/tandem/com.
2261 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
2263 *) Added SHA1 password encryption support to easy migration from
2264 Netscape servers. See support/SHA1 for more information.
2265 Caused the separation of ap_md5.c into md5, sha1 and a general
2266 ap_checkpass.c with just a validate_passwd routine. Added a
2267 couple of flags to support/htpasswd. Some reuse of the to64()
2268 function; hence renamed to ap_to64().
2269 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
2271 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
2272 with ASCII/EBCDIC conversions in "ident" query.
2273 [David McCreedy <McCreedy@us.ibm.com>]
2275 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
2276 Change "Power Macintosh" to Power* so if uname prints "Power Book"
2277 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
2279 *) Fix SIGSEGV on some systems because the Vary fix below included
2280 a call to table_do with a variable argument list that was not
2281 NULL terminated. Replaced with better implementation. [Roy Fielding]
2283 Changes with Apache 1.3.7 [not released]
2285 *) The "Vary" response header field is now sanitised right before
2286 the header is sent back to the client. Multiple "Vary" fields
2287 are combined, and duplicate tokens (e.g., "Vary: host, host" or
2288 "Vary: host, negotiate, host, accept-language") are reduced to
2289 single instances. This is a better solution than the force-no-vary
2290 one (which is still valid for clients that can't cope with Vary
2291 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
2293 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
2295 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
2296 least on Linux and FreeBSD for now.
2299 *) Win32: More apache -k restart work. Restarts are now honored
2300 immediately and connections in the listen queue are -not- lost.
2301 This is made possible by the use of the WSADuplicateSocket()
2302 call. The listeners are opened in the parent, duplicated, then
2303 the duplicates are passed to the child. The original listen sockets
2304 are not closed by the parent across a restart, thus the listen queue
2306 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2308 *) Fix handling of case when a client has sent "Expect: 100-continue"
2309 and we are going to respond with an error, but get stuck waiting to
2310 discard the body in the pointless hope of preserving the connection.
2311 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
2313 *) Fix 'configure' to work correctly with SysV-based versions of
2314 'tr' (consistent with Configure's use as well). [Jim Jagielski]
2316 *) apxs: Add "-S var=val" option which allows for override of CFG_*
2317 built-in values. Add "-e" option which works like -i but doesn't
2318 install the DSO; useful for editing httpd.conf with apxs. Fix
2319 editing code so that multiple invocations of apxs -a will not
2320 create duplicate LoadModule/AddModule entries; apxs can now be
2321 used to re- enable/disable a module. [Wilfredo Sanchez]
2323 *) Win32: Update the server to use Winsock 2. Specifically, link with
2324 ws2_32.lib rather than wsock32.lib. This gives us access to
2325 WSADuplcateSocket() in addition to some other enhanced comm APIs.
2326 Win 95 users may need to update their TCP/IP stack to pick up
2327 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
2328 [Bill Stoddard stoddard@raleigh.ibm.com]
2330 *) Win32: Redirect CGI script stderr (script debug info) into the
2331 error.log when CGI scripts fail. This makes Apache on Win32
2332 behave more like Unix.
2333 [Bill Stoddard stoddard@raleigh.ibm.com]
2335 *) Fixed `httpd' usage display: -D was missing.
2336 [Ralf S. Engelschall] PR#4614
2338 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
2339 [Ralf S. Engelschall] PR#4561, PR#4562
2341 *) OS/2: Fix problem with accept lock semaphores where server would die with
2342 "OS2SEM: Error 105 getting accept lock. Exiting!"
2343 [Brian Havard] PR#4505
2345 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
2346 [Randy Terbush <randy@covalent.net>]
2348 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
2349 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
2351 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
2352 command potentially _is_ GCC. [Ralf S. Engelschall]
2354 *) Fix apxs build issues on AIX
2355 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
2357 *) DocumentRoot Checking: Under previous versions, when Apache
2358 first started up, it used to do a stat of each DocumentRoot to

2368 *) Win32: The query switch "apache -S" didn't exit after showing the
2369 vhost settings. That was inconsistent with the other query functions.
2370 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
2372 *) Win32: Changed behaviour of apache -k restart.
2373 Previously, the server would drain all connections in the stack's
2374 listen queue before honoring the restart. On a busy server, this
2375 could take hours. Now, a restart is honored almost immediately.
2376 All connections in Apache's queues are handled but connections in
2377 the stack's listen queue are discarded. Restart triggered by
2378 MaxRequestPerChild is unchanged.

2412 *) The source is now quad (long long) aware as needed. Specifically,
2413 the Configure process determines the correct size of off_t and
2414 *void. When the OS/platform/compiler supports quads, ap_snprintf()
2415 provides for the 'q' format qualifier (if quads are not available,
2416 'q' is silently "demoted" to long). [Jim Jagielski]

2700 This allows for special configurations like

2702 DefaultType gargle/blurb
2704 Additionally, add the Content-Encoding: header to FTP proxy replies
2705 when the encoding is defined (by the AddEncoding directive).
2706 Because it was missing, it was almost impossible to browse compressed
2707 files using the FTP proxy (works now perfectly in Communicator).

2880 *) src/support/: The ApacheBench benchmark program was overhauled by
2881 David N. Welton: you can now have it generate an HTML TABLE, presumably
2882 for integration into other HTML sources. David updated the ab man page
2883 as well and added some missing descriptions. Thanks!
2884 [David N. Welton <davidw@prosa.it>]
2886 *) Win32: The filename validity checker now allows filenames containing
2887 characters in the range 0x80 to 0xff (for example accented characters).
2888 [Paul Sutton] PR#3890
2890 *) Added conditional logging based upon environment variables to
2891 mod_log_config. mod_log_referer and mod_log_agent
2892 are now deprecated. [Ken Coar]
2894 *) Allow apache acting as a proxy server to relay the real
2895 reason of a failure to a client rather than the "internal
2896 server error" it does currently. The general exposure mechanism
2897 can be triggered by any module by setting the "verbose-error-to"
2898 note to "*"; this allows more than just proxy errors to be exposed.
2899 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
2901 *) Moved man pages for ab and apachectrl to section 8.
2902 [Wilfredo Sanchez, Roy Fielding]
2904 *) Added -S option to install.sh so that options can be passed to
2905 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
2907 *) Tweak modules Makefile generated by Configure so that it handles
2908 the test case of no modules being selected. [chaz@reliant.com]
2910 *) Added a <LimitExcept method ...> sectioning directive that allows
2911 the user to assign authentication control to any HTTP method that
2912 is *not* given in the argument list; i.e., the logical negation
2913 of the <Limit> directive. This is particularly useful for controlling
2914 access on methods unknown to the Apache core, but perhaps known by
2915 some module or CGI script. [Roy Fielding, Tony Finch]
2917 *) Prevent apachectl from complaining if the PIDFILE exists but
2918 does not contain a process id, as might occur if the server is
2919 being rapidly restarted. [Wilfredo Sanchez]
2921 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
2923 *) Entity tag comparisons for If-Match and If-None-Match were not being
2924 performed correctly -- weak tags might cause false positives. Also,
2925 strong comparison wasn't properly enforced in all cases.

2928 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
2931 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
2932 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
2934 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
2935 to util.c for parsing an HTTP header field value to extract the next
2936 list item, taking into account the possible presence of nested comments,
2937 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
2938 insignificant whitespace and lowercases non-quoted tokens.
2939 [Roy Fielding] PR#2065
2941 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
2942 code different from 500. This allows the proxy to, e.g., return
2943 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
2945 *) Fix ordering of language variants for the case where the traditional
2946 negotiation algorithm is being used with multiple language variants
2947 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
2949 *) Do not round the TCN quality calculation to 5 decimal places,
2950 unlike RFC 2296, because the calculation might need 12 decimal places
2951 to get the right result. [Roy Fielding]
2953 *) Remove unused code to disable transparent negotiation when
2954 negotiating on encoding only, as we now handle encoding too
2955 (though this is nonstandard for TCN), remove charset=ISO-8859-1
2956 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
2957 some debugging statements within mod_negotiation. [Koen Holtman]
2959 *) Fixed a rare memory corruption possibility in mod_dir if the index
2960 file is negotiable and no acceptable variant can be found.
2961 [Dean Gaudet, Roy Fielding, Martin Kraemer]
2963 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
2964 searching the Win32 registry for script interpreters.
2967 *) Win32: The compiled-in default filename for the error log is now
2968 error.log, which matches the default in the distributed httpd.conf.
2971 *) Win32: Any error messages from -i or -u command line options are now
2972 displayed on the console output rather than sent to the error log.
2973 Also the "Running Apache..." message is not output unless Apache is
2974 going to serve requests. [Paul Sutton]
2976 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
2977 and use a private significator ('$apr1$') to mark passwords as
2978 being smashed with our own algorithm. Also abstract the password
2979 checking into a new ap_validate_password() routine. [Ken Coar]
2981 *) Win32: The filename validity checker now allows "COM" but refuses
2982 access to "COM1" through "COM4". This allows filenames such
2983 as "com.name" to be served. [Paul Sutton] PR#3769.
2985 *) BS2000: Adapt to the new ufork() system call interface which will
2986 make subtasking easier on the OSD/POSIX mainframe environment.
2989 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
2990 ap_compat.h. [David White <david@persimmon.com>] PR#3725
2992 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
2993 use `.db' instead of `.pag' not only for FreeBSD, but also when
2994 the NDBM library looks like Berkeley-DB based.
2995 [Ralf S. Engelschall] PR#3773
2997 *) Add ability to handle DES or MD5 authentication passwords.
2998 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
3000 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
3002 *) SECURITY: Avoid some buffer overflow problems when escaping
3003 quoted strings. (This overflow was on the heap and we believe
3004 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
3006 *) Let src/Configure be aware of CFLAGS options starting with plus
3007 signs as it's the case for the HP/UX compiler.
3008 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
3010 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
3011 and check to see if the tar we wind up with supports '-h'.
3012 [Jim Jagielski] PR#3671
3014 *) A consistent and conservative style for all shell scripts has been
3015 implemented. Basically, all shell string tests use the traditional
3016 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
3017 to protect against bare null variable strings (ie: wrapping both
3018 sides with double quotes and prepending 'x'). 'x' was chosen
3019 because it's more universal and hopefully easier for old shell
3020 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
3023 *) The status module now prints out both the main server generation as
3024 well as the generation of each process. Also, the vhost info is
3025 printed with '?notable'. [Jim Jagielski]
3027 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
3028 and this makes its functions available to things in src/support.
3031 Changes with Apache 1.3.4
3033 *) Renamed macros status_drops_connection to ap_status_drops_connection
3034 and vestigial scan_script_header to ap_scan_script_header_err,
3035 mostly for aesthetic reasons. [Roy Fielding]
3037 *) The query switch "httpd -S" didn't exit after showing the
3038 vhost settings. That was inconsistent with the other query functions.
3041 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
3042 filename to the end of the STANDARD_MODULE_STUFF. Its
3043 presence at the beginning prevented reporting of the filename
3044 for modules compiled before 1 January 1999. [Ken Coar]
3046 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
3047 to detect and prevent access to special DOS device file names.
3048 [Paul Sutton, Ken Parzygnat]
3050 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
3051 and Makefile_win32_debug.txt (debug build) that work on Win95.
3052 Run each of the following from the src directory:
3053 nmake /f Makefile_win32.txt # compiles normal build
3054 nmake /f Makefile_win32.txt install # compiles and installs
3055 nmake /f Makefile_win32.txt clean # removes compiled junk
3056 nmake /f Makefile_win32_debug.txt # compiles debug build
3057 nmake /f Makefile_win32_debug.txt install
3058 nmake /f Makefile_win32_debug.txt clean
3061 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
3062 to build binary distributions. [Lars Eilebrecht]
3064 *) IndexOptions SuppressColumnSorting only turned off making
3065 the column headers anchors; you could still change the display
3066 order by manually adding a '?N=A' or similar query string to the
3067 URL. Now SuppressColumnSorting locks in the sort order so
3068 it can't be overridden this way. [Ken Coar]
3070 *) Added IndexOrderDefault directive to supply a default sort order
3071 for FancyIndexed directory listings. [Ken Coar] PR#1699
3073 *) Change the ap_assert macro to a variant that works on all platforms.
3074 [Richard Prinz <richard.prinz@cso.net>] PR#2575
3076 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
3077 search for an underscore on dlsym() (as it's already the case
3078 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
3080 *) Small fix for mod_env.html: The module was documented as to be _not_
3081 compiled into Apache per default, although it _IS_ compiled into
3082 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
3084 *) Instead of fixing a bug in the generation procedure for config.status (a
3085 backslash was missing) we remove the bug together with it's complete
3086 context because the special cases of the past can now no longer occur
3087 because of the recent magic for the --with-layout default.
3088 [Ralf S. Engelschall] PR#3590
3090 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
3091 making sure the src/support/ tools are _forced_ to be build last (they
3092 depend on other libraries).
3093 [Markus Theissinger <markus.theissinger@gmx.de>]
3095 *) Fix installation procedure: Now that os-inline.c is actually used (a
3096 recently fixed bug prevented this) we need to also install os-include.c
3097 in addition to os.h into the PREFIX/include/ location or building of
3098 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
3100 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
3101 allow us to distinguish between a garbled DSO (or even a file which isn't
3102 an Apache module DSO at all) and a DSO which doesn't match the current
3103 Apache API. [Ralf S. Engelschall] PR#3152
3105 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
3106 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
3107 match case insensitive (this especially avoids nasty patterns like
3108 `[tT][eE][sS][tT]'). Second two additional internal map functions
3109 `escape' and `unescape' were added which can be used to escape/unescape
3110 to/from hex-encodings in URLs parts (this is especially useful in
3111 combination with map lookups).
3112 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
3114 *) Renamed the macro escape_uri() to ap_escape_uri() which was
3115 forgotten (because it was a macro) in the symbol renaming process.
3116 [Ralf S. Engelschall]
3118 *) Fix some inconsistencies related to the scopes of directives. The only
3119 user visible change is that the directives `UseCanonicalName' and
3120 `ContentDigest' now use the (more correct) `Options' scope instead of
3121 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
3123 *) Using DSO, the Server token was being mangled. Specifically, the
3124 module's token was being added first before the Apache token. This
3125 has been fixed. [Jim Jagielski]
3127 *) Major overhaul of mod_negotiation.c, part 2.
3128 - properly handle "identity" within Accept-Encoding.
3129 - allow encoded variants in RVSA negotiation and let them appear in
3130 the Alternates field using the non-standard "encoding" tag-list.
3131 - fixed both negotiation algorithms so that an explicitly accepted
3132 encoding is preferred over no encoding if "identity" is not
3133 included within Accept-Encoding.
3134 - added ap_array_pstrcat() to alloc.c for efficient concatenation
3135 of large substring sequences.
3136 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
3139 *) Major overhaul of mod_negotiation.c, part 1.
3140 - cleanups to mod_negotiation comments and code structure
3141 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
3142 support for everything in the upcoming HTTP/1.1
3143 revision (draft-ietf-http-v11-spec-rev-06.txt).
3144 - language tag matching also handles tags with more than 2
3146 - empty Accept, Accept-Language, Accept-Charset headers are
3147 processed correctly; previously an empty header would make all
3148 values acceptable instead of unacceptable.
3149 - allowed for q values in Accept-Encoding
3150 - added support for transparent content negotiation (rfc2295 and
3151 rfc2296) (though we do not implement all features in these drafts,
3152 e.g. no feature negotiation). Removed old experimental version.
3153 - implemented 'structured entity tags' for better cache correctness
3154 (structured entity tags ensure that caches which can deal with Vary
3155 will (eventually) be updated if the set of variants on the server
3157 - this involved adding a vlist_validator element to request_rec
3158 - this involved adding the ap_make_etag() function to the global API
3159 - modified guessing of charsets used by Apache negotiation algorithm
3160 to guess 'no charset' if the variant is not a text/* type
3161 - added code to sort multiviews variants into a canonical order so that
3162 negotiation results are consistent across backup/restores and mirrors
3163 - removed possibility of a type map file resolving to another type map
3164 file as its best variant
3165 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
3167 *) RFC2396 allows the syntax http://host:/path (with no port number)

3175 *) Correct some filename case assumptions from WIN32 to
3176 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]
3178 *) For %v log ServerName regardless of the UseCanonicalName
3179 setting (similarly for %p). [Dean Gaudet]
3181 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
3182 rather late (too late for some invocations of TestCompile).
3183 This improves the make environment available to TestCompile and
3184 the *.module scripts. [Martin Kraemer]
3186 *) The hashbang emulation code in ap_execve.c would interpret
3187 #!/hashbang/scripts correctly, but failed to fall back to a
3188 standard shell for scripts which did NOT start with #!
3189 Now SHELL_PATH is started in these cases. [Martin Kraemer]
3191 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
3194 *) Update APXS manual page: some -q option arguments were missing
3195 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
3197 *) Cleanup the command line options: `-?' was documented to show
3198 the usage list but does it with an error because `?' is not a valid
3199 command. OTOH a lot of users expect `-h' to print such a usage list and
3200 instead are annoyed for ages by our huge unreadable list of directives.
3201 So we now changed the command line options this way:
3203 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
3204 very similar to the popular linker option.
3206 Intent: while -l gives the small list of modules, -L now gives the
3207 large list of directives implemented by these modules. This is also
3208 consistent with -v (short version info) and -V (large version info).
3210 Intent: it's now the expected option ;-)
3211 The manual page was adjusted accordingly.
3212 [Ralf S. Engelschall] PR#2714
3214 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
3215 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
3217 *) Removed recently introduced bugs and disfigurements in APACI:
3218 o fixed argument line processing: using $args was broken: It was not
3219 initialized and using args="$args $apc_option" and even args="$args
3220 \"$apc_option\"" fails in the second processing round for any arguments
3221 containing whitespaces. The only correct way is to use the construct
3222 "$@" (but not possible here) or iterate _both_ times over the implicit
3223 argument line (no argument to for-loop) which is what we now use.
3224 o make --with-layout=Apache the default without creating
3225 redundancy (copying the --with-layout block in the argument parsing
3226 loop). We achieve this by using the "$@" construct together with the
3227 `set' command to prepend --with-layout=Apache to the command line in
3228 case --with-layout is not used.
3229 o fixed auto-suffix handling now that config.layout exists.
3230 Paths which are auto-suffixed are marked with a trailing plus sign in
3231 config.layout and every path now can be marked this way (not only the
3232 four paths for which we do it currently). Additionally the suffix is
3233 no longer a static one. Instead it's now `/<target>' where <target> is
3234 the argument of the --target option or per default `httpd'.
3235 o allow also tabs (and only spaces) where we match whitespaces
3236 o various fixes and cleanups related to used shell coding style
3237 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
3238 o trimmed output of --help to fit into 80 columns
3239 [Ralf S. Engelschall]
3241 *) Added two new core API functions, ap_single_module_configure() and
3242 ap_single_module_init(), which are now used by mod_so to configure a module
3243 after loading. [Ralf S. Engelschall]
3245 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
3246 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
3247 of ap_config.h to allow serialized accept for multiport listens.
3248 [Roy Fielding, Curt Sampson] PR#3120
3250 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
3251 of ap_config.h that would skip several defines if DEFAULT_GROUP
3252 was overridden. [Roy Fielding]
3254 *) PORT: The I86 version of DGUX has support for strncasecmp and
3255 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
3257 *) Fix ordering of definitions in ap_config.h so that ap_inline is
3258 defined before it might be used. [Victor Khimenko]
3260 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
3261 [Tom Serkowski <tks@bsdi.com>] PR#3453
3263 *) Make generation of src/Configuration.apaci more robust: It failed to
3264 differenciate between modules when one module name was a postfix of
3265 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
3266 just XXX (think about totally non-standard names like "apache_ssl", too).
3267 [Ralf S. Engelschall] PR#3380
3269 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
3270 since 1.3b7) and make whitespace handling more robust (it failed horrible
3271 when whitespaces were present in the arguments of -D options).
3272 [Ralf S. Engelschall] PR#3240
3274 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
3275 creates an external package shadow tree in DIR before the local build
3276 shadow tree is generated under DIR. This way one can have the extracted
3277 Apache distribution tree read-only on NFS or CDROM and still build Apache
3278 from these sources. An automatically triggered VPATH-like mechanism is
3279 provided through the TOP variable, too.
3280 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez@apple.com>]
3282 *) Fix negotiation so that a Vary response header is correctly
3283 generated when, for a particular dimension, variants only vary
3284 in having or not having a value for that dimension. [Paul Sutton]
3286 *) Fix negotiation so that we prefer an encoded variant over an
3287 unencoded variant if the user-agent explicitly says it can
3288 accept that encoding. Previously we always preferred the unencoded
3290 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
3292 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
3293 and the usage page was inconsistent with the functionality and manpage.
3294 [Ralf S. Engelschall]
3296 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
3297 They can occur multiple times and their arguments (`xxx') are passed AS
3298 IS to the compiler/linker command. [Ralf S. Engelschall]
3300 *) Fixed possible (but harmless in practice) bug in the DBM lookup
3301 procedure of mod_rewrite: very long keys were truncated.
3302 [Ralf S. Engelschall]
3304 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
3305 identifier, currently "Apache" and "GNU" are pre-defined in the file
3306 config.layout. Custom layouts are possible by using FILE:ID as the
3307 argument where the layout ID is taken from FILE.
3309 The config.layout file consists of <Layout ID>..</Layout> sections
3310 where inside those sections "path_variable: path_value" pairs can be
3311 specified. These lines are converted to path_variable='path_value'.
3313 *) Add a DefaultLanguage directive so that files missing a language
3314 extension (e.g., .fr, .de) can be labelled as being some other
3315 default language. DefaultLanguage can appear in <Directory> and
3316 <Files> containers as well as .htaccess files. [Paul Sutton]
3319 *) Fix TARGET configuration when configuring and installing using
3320 APACI configure. TARGET now defines the basename of the configuration
3321 file, startup script, manual page, etc. log_error_core() now reports
3322 the server binary name given by argv[0]. TARGET can now also be defined
3323 with --target=TARGET parameter passed to APACI configure.

3362 *) Add APACI --suexec-docroot and --suexec-logfile options which can be
3363 used to set the document root directory (DOC_ROOT) and the suexec
3364 logfile (LOG_EXEC), respectively. Additionally the --layout option
3365 was changed to show more information about the suEXEC setup.

3368 *) Added the last two WebDAV status codes of 424 (Failed Dependency)
3369 and 507 (Insufficient Storage) for use by third-party modules.
3372 *) Enabled all of the WebDAV method names for use by third-party
3373 modules, Limit, and Script directives. That includes PATCH,
3374 PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.
3375 Improved mod_actions.c so that it can use any of the methods
3376 defined in httpd.h. Added ap_method_number_of(method) for

3403 since it often includes file path info. Enable sending of error-notes
3404 on a 501 (Method Not Implemented). [Roy Fielding] PR#3173
3406 *) http_config.c would respond with 501 (Method Not Implemented) if a
3407 content type handler was specified but could not be found, which
3408 should have been a 500 response. Likewise, mod_proxy.c would responsd
3409 with a 501 if the URI scheme is unrecognized instead of the correct
3410 response of 403 (Forbidden). [Roy Fielding]

3416 unavailable, an empty string was printed which was 2 bytes short.
3417 The size and description columns were therefore not aligned correctly.

3430 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
3431 in the Configuration[.apaci] file. Two special and important variants are
3432 supported for the option argument: first BEGIN:foo which permutes module
3433 mod_foo with the begin of the module list, i.e. it `moves' the module to
3434 the begin of the list (gives it lowest priority). And second foo:END
3435 which permutes mod_foo with the end of the module list, i.e. it `moves'
3436 the module to the end of the list (gives it highest priority).

3507 Changes with Apache 1.3.3
3509 *) Added a complete implementation of the Expect header field as
3510 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
3511 response when we already know the final status, which is mighty
3512 useful for PUT responses that result in 302 or 401. [Roy Fielding]
3514 *) Remove extra trailing whitespace from the getline results as part
3515 of the protocol processing, which is extra nice because it works
3516 between continuation lines, is almost no cost in the normal case
3517 of no extra whitespace, and saves memory. [Roy Fielding]
3519 *) Added new HTTP status codes and default response bodies from the
3520 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
3521 HTTP Extension Framework (510) specifications. Did not add the
3522 WebDAV 424 and 425 codes because they are bogus. We don't use any
3523 of these codes yet, but they are now available to 3rd-party modules.
3526 *) Fix a possible race condition between timed-out requests and the
3527 ap_bhalfduplex select that might result in an infinite loop on
3528 platforms that do not validate the descriptor. [Roy Fielding]

3632 and to avoid problems under platforms where only version 2.x is present.

3639 You now must define a BS2000Account name for the server User.
3640 This has fewer security implications than the old approach.
3643 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
3644 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
3645 platform to make the braindead HPUX linker happy. Notice, for the module
3646 DSOs we don't have to use this, because these are loaded manually (and
3647 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968

3658 *) Make PrintPath work generically instead of having one version
3659 strictly for OS/2. [Jim Jagielski, Brian Havard]
3661 *) Fix the recently introduced C header file checking: We now use the C
3662 pre-processor pass only (and no longer the complete compiler pass) to
3663 determine whether a C header file exists or not. Because only this way
3664 we're safe against inter-header dependencies (which caused horrible
3665 portability problems). The only drawback is that we now have a CPP
3666 configuration variable which has to be determined first (we do a similar
3667 approach as GNU Autoconf does here). When all fails the user still has
3668 the possibility to override it manually via APACI or src/Configuration.
3669 As a fallback for the header check itself we can directly check the
3670 existance of the file under /usr/include, too.
3671 [Ralf S. Engelschall] PR#2777

3701 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
3702 platform, because it's only supported under version 4.0 and higher. But
3703 because our GuessOS is still unaware of Digital UNIX versions and the
3704 -msym is just to optimize the DSO statup time a little bit it's safe and
3705 best when we leave it out now. [Ralf S. Engelschall] PR#2969
3707 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
3708 functions: First all three functions no longer fail on strings containing
3709 "%" chars and second ap_log_printf() no longer does a double-formatting
3710 (instead it directly passes through the message to be formatted to the
3711 real internal formatting function). [Ralf S. Engelschall] PR#2941
3713 *) Allow "Include" directives anywhere in the server config
3714 files (but not .htaccess files). [Ken Coar] PR#2727
3716 *) The proxy was refusing to serve CONNECT requests except to
3717 port 443 (https://) and 563 (snews://). The new AllowCONNECT
3718 directive allows the configuration of the ports to which a
3719 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
3721 *) mod_expires will now act on content that is not sent from a file
3722 on disk. Previously it would never add an Expires: header to
3723 any response that did not come from a file on disk; the only
3724 case where it still doesn't (and can't) add one for that type of
3725 content is if you are using a modification date based setting.
3726 [Marc Slemko, Paul Phillips <paulp@go2net.com>]
3728 *) Problems encountered during .htaccess parsing or CGI execution
3729 that lead to a "500 Server Error" condition now provide explanatory
3730 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
3733 *) Add NameWidth keyword to IndexOptions directive so that the
3734 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
3737 *) Recognize lowercase _and_ uppercase `uname' results under
3738 SCO OpenServer. [David Coelho <drc@ppt.com>]
3740 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
3741 a common problem of (mis-administrated?) IIS servers, make the apache
3742 proxy immune to these errors (and ignore the duplicates, but log
3743 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
3745 *) The <IfModule and <IfDefine block starting directives now only
3746 allow exactly one argument. Previously, the optional negation
3747 character '!' could be separated by whitespace without a syntax
3748 error being reported, albeit defeating the IfModule functionality
3749 (enclosed directives would ALWAYS be executed). By using the
3750 stricter syntax, these hard-to-track errors can be avoided.
3753 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
3754 cause the standalone FancyIndexing directive to logically OR
3755 into any existing IndexOptions settings rather than wiping
3756 them out. [Ken Coar]
3758 *) Changes in ftp proxy: make URL parsing simpler by using the
3760 + Add display of the "current directory" in cases where it's
3761 different from the supplied path (e.g., ftp://user@host/ lives
3762 in /home/user, not in /, therefore clicking on "../" in the
3763 starting directory might send us to /home/).
3764 + When ftp login fails, (esp. when a user name was part of the
3765 URL already), we now return [401 Unauthorized ] to allow the
3766 browser to pop up an authorization dialog. This makes passwords
3767 slightly less visible (they don't appear in the regular log files)
3768 and implements a functionality that other www proxy servers
3772 *) Triggered by the recent "Via:" header changes, the proxy module would
3773 dump core for replies with invalid headers (e.g., duplicate
3774 "HTTP/1.0 200 OK" lines). These errors are now logged and the
3775 core dump is avoided. Also, broken replies are not cached.
3776 [Martin Kraemer] PR#2914
3778 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
3779 plop gmon.out profile data for each child [Doug MacEachern]

3782 config.status script to be immune against arguments with whitespaces.
3783 [Yves Arrouye <yves@apple.com>] PR#2866
3785 *) Replace the inlined information grabbing stuff for the configuration
3786 adjustment feature (no --without-confadjust) with calls to a new helper
3787 script `buildinfo.sh' which is both more flexible and already proofed to
3788 be more robust against platform differences. This mainly fixes the
3789 recently occured ``sed: command garbled: ...'' problems.

3810 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
3811 5 to 10 because there are some users out there who always have 5 to 8
3812 variables in one RewriteRule and had to patch mod_rewrite.h for every
3813 release. So 15 should be now more than enough, even for them. (I never
3814 needed more than 4 in my RewriteRules ;-)
3815 [Ralf S. Engelschall]
3817 *) Make the proxy generate and understand Via: headers
3820 *) Change the proxy to use tables instead of array_headers for
3821 the header lines. [Martin Kraemer]
3823 *) Make sure the config.status file is not overridden when just
3824 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
3826 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
3827 provide a way to trace API changes that add functionality but do
3828 not create a compatibility issue for precompiled modules, etc.
3829 See include/ap_mmn.h for more details. [Randy Terbush]
3831 *) Fix suexec installation under `make install root=xxx' situation.
3832 [Ralf S. Engelschall]
3834 *) Extend the output of the -V switch to include the paths of all
3835 compiled-in configuration files, if they were overridden at
3836 compile time, for least astonishment of the user.
3839 *) When READing a request in ExtendedStatus mode, the "old"
3840 vhost, request and client information is not displayed.
3843 *) STATUS is no longer available. Full status information now
3844 run-time configurable using the ExtendedStatus directive.
3847 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
3848 cpu time attacks) in header parsing. Add ap_overlap_tables(),
3849 a function which can be used to perform bulk update operations
3850 on tables in a more efficient manner. [Dean Gaudet]
3852 *) SECURITY: Added compile-time and configurable limits for
3853 various aspects of reading a client request to avoid some simple
3854 denial of service attacks, including limits on maximum request-line

4047 *) mod_mmap_static will no longer take action on requests unless at
4048 least one "mmapfile" directive is present in the configuration.
4049 This experimental module has to do some black magic to operate
4050 inside the current API and thus creates side-effects for other

4224 than strcmp() to check for parent directory-ness of an entry. Oh, and
4225 make sure the parent directory (if displayed) is *always* listed first
4226 regardless of the sort key. Overall performance winnage should be good
4227 in CPU time, instruction cache, and memory usage, particularly for large
4228 directories. [Ken Coar]

4237 *) Add httpd -t (test) option for running configuration syntax tests only.
4238 If something is broken it complains and exits with a return code
4239 non-equal to 0. This can be used manually by the user to check the Apache
4240 configuration after editing and is also automatically used by apachectl
4241 on (graceful) restart command to make sure Apache doesn't die on restarts
4242 because of a configuration which is now broken since the last (re)start.
4243 This way `apachectl restart' can be used inside cronjobs without having

4356 *) Change usage of perror()+fprintf(stderr,...) in mod_rewrite to
4357 more proper ap_log_error() variants.
4358 [Ralf S. Engelschall]
4360 *) Make sure the argument for the --add-module option to APACI's configure

4383 ap_spawn_child_err became ap_spawn_child
4384 ap_spawn_child_err_buff became ap_bspawn_child
4385 spawn_child was obsoleted and moved to compat.h
4388 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
4389 programs: ap_spawn_child_err() is used and the Win32 case now uses
4390 CreateProcess() instead of a low-level execl() (which caused problems in
4391 the past under Win32).

4394 *) A few cosmetics and trivial enhancements to APXS to make the
4395 generated Makefile more user friendly. [Ralf S. Engelschall]
4397 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
4398 was updated to use the normal apache error processing, thereby allowing
4399 proxy errors to be treated by ErrorDocument's as well. For this
4400 purpose, a new module-to-core communication variable "error-notes"
4401 was introduced; the proxy (and possibly other modules) communicates
4402 its error text using this variable. Its content is copied to a new
4403 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
4404 The old proxy special error routine ap_proxy_log_uerror()
4405 was replaced by regular ap_log_error() calls, many messages were made

4478 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
4480 *) The proxy cache would store an incorrect content-length in the cached
4481 file copy after a cache update. That resulted in repeated fetching
4482 of the original copy instead of using the cached copy.
4483 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
4485 *) The Makefiles assumed that DSO files are build via $(LD). This
4486 is broken for two reasons: First we never defined at least LD=ld
4487 somewhere to make sure this works (it was silently assumed that most Make
4488 provide a built-in LD definition - ARGL!) and second using the generic LD
4489 variable is not the truth. Instead a special variable named LD_SHLIB is
4490 reasonable because although "ld" is usually the default, the command for
4491 building DSO files can be "libtool" or even "cc" on some systems.
4492 [Ralf S. Engelschall]
4494 *) Replace the AddVersionPlatform directive with ServerTokens which
4495 provides for more control over the format of the Server:

4498 API function instead. [Jim Jagielski]

4504 not retrieved in src/Configure and thus was not useable.
4505 [Ralf S. Engelschall]
4507 *) Various Makefile consistency cleanups:
4508 - make OSDIR also automatically be relative to src/ like INCDIR
4509 - SUBDIRS is now generated in src/Makefile only and not in
4510 Makefile.config because it is a local define for this location.
4511 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
4512 any Makefile but make sure that at least the "-K inline" is kept in
4514 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
4515 - updated the dependencies theirself
4516 - removed not existing SHLIB variable from "clean" targets
4517 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
4518 already exists and OBJS_PIC are also just plain objects and have not
4519 directly to do with "shared" things. The only difference is that they
4520 contain PIC. So OBJS_PIC is the more canonical name.
4521 - Updated the Makefile-dependency lines for OBJS_PIC
4522 - Removed the Makefile-dependency line in Configure to avoid double
4524 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
4525 of xxx.lo as GNU libtool does with its PIC objects
4526 - reduce local complexity in modules Makefile.tmpl by moving the last
4527 existing target "depend" to the generation section in Configure, too.
4528 - removed the historical $(SPACER) which was used in the past together
4529 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
4530 is no longer needed.
4531 - force the build and run of the gen_xxx programs under main/ as the
4532 first step before building the objects because it looks cleaner
4533 [Ralf S. Engelschall]
4535 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
4538 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
4541 *) WIN32: Don't force ISAPI headers to finish with \n.
4542 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
4544 *) When opening "configuration" files (like httpd.conf, htaccess
4545 and htpasswd), Apache will not allow them to be non-/dev/null
4546 device files. This closes a DoS hole. At the same time,
4547 we use ap_pfopen to open these files to handle timeouts.
4548 [Jim Jagielski, Martin Kraemer]
4550 *) Apache will now log the reason its httpd children exit if they exit
4551 due to an unexpected signal. (It requires a new porting define,
4552 SYS_SIGLIST, which if defined should point to a list of text
4553 descriptions of the signals available. See PORTING.) [Dean Gaudet]
4555 *) WIN32: chdir() doesn't make sense in a multithreaded environment
4556 like WIN32. Before, Win32 CGI's could have had sporadic failures
4557 if a chdir call from one thread was made between another chdir call
4558 and a spawn in another thread. So, for now don't chdir for CGI scripts
4559 in WIN32. The current CGI "spec" is unclear as to whether it's
4560 necessary. Long-term fix is to either serialize the chdir/spawn combo
4561 or use WIN32 native calls to spawn a process. This temp fix was
4562 necessary to remove this as a showstopper for 1.3's release.
4565 *) Cleanup the suEXEC support in APACI and make it more safe:
4566 1. Add big fat hint in INSTALL about risks and to read the
4567 htdocs/manual/suexec.html document before using the suexec-related
4569 2. Make sure the user has at least provided one --suexec-xxxx option
4570 (specifies suEXEC parameters) in addition to --enable-suexec option.
4571 If only --enable-suexec is given APACI stops with a hint to INSTALL
4572 and htdocs/manual/suexec.html documents.
4573 3. Provide two additional --suexec-xxxx options to make the suEXEC
4574 configuration complete (especially for package maintainers who else
4575 had to patch the source tree) by providing ways to configure minimal
4576 UID/GID and safe PATH, too.
4577 [Ralf S. Engelschall]
4579 *) Cleanup of the `configure --shadow' process:
4580 - make sure the configure script creates its temporary files in the
4581 shadow tree to avoid conflicts with parallel configure runs
4582 - removed unnecessary option "-r" from "rm" call for Makefiles
4583 - make sure the configure scripts creates the shadow-wrapper Makefile
4584 only when no shadow trees already exists
4585 - make sure "make distclean" removes the shadow-wrapper Makefile but only
4586 when no more shadow trees exists
4587 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
4588 as fast (in the past it needed 70sec, now it runs just 38sec)
4589 - make sure CVS does not complain about the created files
4590 Makefille.<gnutriple> and directories src.<gnutriple>
4591 [Ralf S. Engelschall]
4593 *) Added the ap_add_version_component() API routine and the
4594 AddVersionPlatform core directive. The first allows modules to
4595 declare themselves in the Server response header field value,
4596 augmenting the SERVER_SUBVERSION define in the Configuration file
4597 with run-time settings (more useful in a loadable-module environment).
4598 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
4599 into the server version string. [Ken Coar] PR#2056
4601 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
4604 *) Emit the "Accept-Range" header for the default handler.
4605 [Brian Behlendorf] PR#1464
4607 *) Add a note to httpd.conf-dist that apache will on some systems fail
4608 to start when the Group # is set to a negative or large positive value.
4611 *) Make sure the module execution order is correct even when some modules
4612 are loaded under runtime (`LoadModule') via the DSO mechanism:
4613 1. The list of loaded modules is now a dynamically allocated one
4614 and not the original statically list from modules.c
4615 2. The loaded modules are now correctly setup by LoadModule for
4616 later use by the AddModule command.
4617 3. When the DSO mechanism for modules is used APACI's `install'
4618 target now enables all created `LoadModule' lines per default because
4619 this is both already expected by the user _and_ needed to avoid
4620 confusion with the next point and reduces the Makefile.tmpl complexity
4621 4. When the DSO mechanism for modules is used, APACI's `install'
4622 target now additionally makes sure the module list is reconstructed
4623 via a complete `ClearModuleList+AddModule...' entry.
4624 5. The support tool `apxs' now also makes sure an AddModule command
4625 is added in addition to the LoadModule command.
4626 6. The modules.c generation was extended to now contain two
4627 comments to make sure no one is confused by the confusing terminology
4628 of loading/linking (we use load=link+load & link=activate instead of
4629 the obvious load=activate & link=link :-( )
4630 This way now there is no longer a difference under execution time between
4631 statically and dynamically linked modules.
4632 [Ralf S. Engelschall]
4634 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
4635 Big Symbol Renaming. [Ralf S. Engelschall]
4637 *) Add a comment to mod_example.c showing the format of a FLAG command
4640 *) Standardized the time format in mod_status to match that of other
4641 places in the code (e.g. DATE_GMT). PR#1551
4643 *) Fix handling of %Z in timefmt strings for those platforms with no time
4644 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
4647 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
4648 feature compatible with 'UseCanonicalName off' by changing
4649 r->server->server_hostname to ap_get_server_name(). And I changed some
4650 functions which use r->server->port to use ap_get_server_port() instead,
4651 because if there's no Port directive in the config r->server->port is 0.
4654 *) get/set_module_config are trivial enough to be better off inline. Worth
4655 1.5% performance boost. [Dean Gaudet]
4657 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
4658 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
4661 *) [BS2000 security] BS2000 needs an extra authentication to initialize
4662 the task environment to the unprivileged User id. Otherwise CGI scripts
4663 would have a way to gain super user access. [Martin Kraemer]
4665 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
4666 absolute path, only log base name of logging source as is done
4667 in unix. [Martin Kraemer]
4669 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
4670 the encoding type from the Accept-Encoding header (if it's there)
4671 and use it in the response, as that's probably what it'll be expecting.
4672 [Ronald.Tschalaer@psi.ch]
4674 *) Fix to mod_alias: translate_alias_redir is dealing with
4675 a URI, not a filename, so the check for drive letters for win32
4676 and emx is not necessary. [Dean Gaudet]
4678 *) WIN32: Allow .cmd as an executable extension.
4679 [Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146
4681 *) Make Apache header files, and some variables, C++ friendly.
4682 [Michael Anderson's <mka@redes.int.com.mx>]
4684 *) Child processes can now "signal" (by exiting with a status
4685 of APEXIT_CHILDFATAL) the parent process to abort and
4686 shutdown the server if the error in the child process was
4687 fatal enough. [Jim Jagielski]
4689 *) mod_autoindex's find_itme() was sensitive to MIME type case.
4690 [Jim Jagielski] PR#2112
4692 *) Make sure the referer_log and agent_log entries in the default httpd.conf
4693 file are also adjusted for the actual relative installation paths.
4694 [Ralf S. Engelschall] PR#2175
4696 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
4698 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
4701 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
4702 Additionally the checks for finding the vendor DSO library were moved
4703 from mod_so.c to Configure because first it needs $PLAT etc. and second
4704 mod_so already uses an abstraction layer and does not fiddle with the
4705 vendor functions itself.
4706 [Jens-Uwe Mager, Ralf S. Engelschall]
4708 *) PORT: Some optimization defines for NetBSD
4709 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
4711 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
4712 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
4714 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
4715 AIX variants should work fine, too. Even AIX 3.x should work). This is
4716 accomplished by using the free DSO emulation code from Jens-Uwe Mager
4717 which we put into a os/unix/os-dso-aix.c file.
4718 [Ralf S. Engelschall]
4720 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
4721 that we should use NET_SIZE_T == int but the include files force size_t.
4722 [Ralf S. Engelschall]
4724 *) Fix two bugs in select() handling in http_main.c.
4727 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
4728 is unset (as it is in situations like timeouts) where it is unclear
4729 whether errno is set or not. [Martin Kraemer]
4731 *) Just having APACI's localstatedir is too general and not enough for most
4732 of the systems. 1.3b6 again required manual APACI patches by package
4733 maintainers from RedHat and FreeBSD because for their filesystem layout a
4734 little bit more flexibility in configuring the paths is needed. Hence we
4735 provide three additional configure options (--runtimedir, --logfiledir,
4736 --proxycachedir) which now can be used for more granular adjustments if
4737 --localstatedir is not enough to fit the particular needs. As a nice
4738 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
4739 [Ralf S. Engelschall]
4741 *) Make the install root for "make install" in APACI's Makefile overrideable
4742 by package authors. This way we are even more friendly to package
4743 maintainers (especially Debian and RedHat) who build for the real prefix
4744 via "configure --prefix=/<real>" but use a different local prefix via
4745 "make root=/tmp/apache install" for rolling the package without bristling
4746 the target location on their system.
4747 [Ralf S. Engelschall]
4749 *) Workaround sed limitations in APACI's configure script by now
4750 substituting in chunks of 50 commands (because for instance HPUX's vendor
4751 sed has a limit of max. 98 commands)
4752 [Ralf S. Engelschall] PR#2136
4754 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
4755 [Ralf S. Engelschall] PR#2140
4757 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
4758 RENAMING process because they are defined as pre-processor macros instead
4759 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
4760 [Ralf S. Engelschall]
4762 *) Workaround braindead AWK's when generating ap_config.h: The split() and
4763 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
4764 [Ralf S. Engelschall] PR#2139
4766 *) Various bugfixes and cleanups for the APACI configure script:
4767 o fix IFS handling for _nested_ situation
4768 o fix Perl interpreter search: take first one found instead of last one
4769 o fix DSO consistency check
4770 o print error messages to stderr instead of stdout
4771 o add install-quiet for --shadow situation to Makefile stub
4772 o reduce complexity by avoiding sed-hacks for rule and module list loops
4773 [Ralf S. Engelschall]
4775 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
4777 *) Make sure the input field separator (IFS) shell variable is explicitly
4778 initialized correctly before _every_ `for' loop and also restored after
4779 the loops. [Ralf S. Engelschall]
4781 *) Make sure that "make install" doesn't overwrite the `mime.types' and
4782 `magic' files from an existing Apache installation. Because people often
4783 customize these for own MIME and content types.
4784 [Ralf S. Engelschall]

4789 *) Fix the path to the ScoreBoardFile in the install-config target, too.
4790 [Ralf S. Engelschall] PR#2105
4792 *) Let "configure" clear out the users parameters (provided as shell
4793 variables) to avoid side-effects in "src/Configure" when the user
4794 exported them (which is not needed, but some users do it).
4795 [Ralf S. Engelschall] PR#2101
4797 *) Provide backward compatibility from some old src/Configuration.tmpl
4798 parameter names to the canonical Autoconf-style shell variable names. For
4799 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
4800 but a hint message is displayed. [Ralf S. Engelschall]

4806 *) Make `configure --compat' more "compatible" by first
4807 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
4808 second by making sure the "avoid-bristling-suffix" /apache is not
4809 appended to sysconfdir, datadir, localstatedir and includedir when
4810 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]

4821 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
4823 *) If you start apache with the -S command line option it will dump
4824 out the parsed vhost settings. This is useful for folks trying
4825 to figure out what is wrong with their vhost configuration.
4826 (Other dumps may be added in the future.) [Dean Gaudet]
4828 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
4829 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
4832 *) Because /usr/local/apache is the default prefix the ``configure
4833 --compat'' option no longer has to set prefix, again. This way the
4834 --compat option honors a leading --prefix option. [Lars Eilebrecht]
4836 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
4837 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
4838 to avoid "discard const" warnings. [Ralf S. Engelschall]
4840 *) If a specific handler is set for a file yet the request still
4841 ends up being handled by the default handler, log an error
4842 message before handling it. This catches things such as trying
4843 to use SSIs without mod_include enabled. [Marc Slemko]
4845 *) Fix error logging for the startup case where ap_log_error() still uses
4846 stderr as the target. Now the default log level is honored here, too.
4847 [Ralf S. Engelschall]
4849 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
4850 long" errors when generating the MODULES entry for src/Makefile
4851 [Ben Hyde, Ralf S. Engelschall]
4853 *) Make sure src/Configure doesn't complain about the old directory
4854 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
4856 Changes with Apache 1.3b6
4858 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
4860 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
4861 interface via the similar but proprietary HP/UX shl_xxx-style system
4862 calls. [Ralf S. Engelschall]
4864 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
4865 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
4866 Make. [Ralf S. Engelschall]
4868 *) ++++ THE BIG SYMBOL RENAMING ++++
4869 To avoid symbol clashes with third-party code compiled into the server,
4870 we globally applied the prefix "ap_" to the following classes of
4872 - Apache provided general functions (e.g., ap_cpystrn)
4873 - Public API functions (e.g., palloc, bgets)
4874 - Private functions which we can't make static (because of
4875 cross-object usage) but should be (e.g., new_connection)
4876 For backward source compatibility a new header file named compat.h was
4877 created which provides defines for the old symbol names and can be used
4878 by third-party module authors.
4881 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
4882 problem under SVR4 is that there is no command flag to force the linker
4883 to export the global symbols of the httpd executable therewith they are
4884 available to the DSO's. Instead of problematic hacks like creating a
4885 dummy.so file (containing dummy references to all global symbols) the
4886 httpd binary is linked against, we use a clean trick stolen from Perl 5:
4887 Placing the Apache core code itself into a DSO library named libhttpd.so.
4888 This way the global symbols _HAVE_ to be exported and thus are available
4889 to any manually loaded DSO's under runtime. To reduce the impact to the
4890 user to null we go even further and create a stub httpd executable which
4891 automatically keeps track of the DSO library loading itself and thus
4892 hides the complete mechanism from the user. Although the generation of
4893 this DSO library is automatically triggered for platforms which
4894 essentially need it (mostly all SVR4-derivates) it can be also enabled
4895 manually via the Rule SHARED_CORE. This can be interesting in the future
4896 where we perhaps exploit this libhttpd.so mechanism for providing nifty
4897 features like graceful upgrades, or whatever.
4898 [Ralf S. Engelschall, Martin Kraemer]
4900 *) Build the libraries before building the rest of the tools. [Ben Hyde]
4902 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
4903 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
4904 conventions while "clean" removes only stuff created by "all" targets,
4905 "distclean" additionally removes the stuff from the configuration
4906 process. This way "make distclean" (hence the name) provides a fresh
4907 source tree as it was for distribution.
4908 [Ralf S. Engelschall]
4910 *) Allow top-level (APACI) Makefile to break on build errors
4911 the same way the src/ subtree Makefiles breaks on them by replacing the
4912 initial APACI sed-subdir-display-kludge with a more clean
4913 variable-passing-solution: variable SDP can optionally hold the subdir
4914 prefix which is consistently used for displaying the subdir movement.
4915 This way even the top-level Makefile can stop correctly on errors as the
4916 user expects. [Ralf S. Engelschall]
4918 *) Fixed ordering of argument checks for RewriteBase directive.
4919 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
4921 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
4922 indicating that a module is being compiled for dynamic loading. Also
4923 remove #define IS_MODULE from modules and add SHARED_MODULE define
4924 to the mak/dsp files. [Alexei Kosut]
4926 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
4927 since we are now logging APLOG_WARNING by default. [Roy Fielding]
4929 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
4931 *) Add documentation file and src/Configuration.tmpl entry for the
4932 experimental mod_mmap_static module. Because although it is and marked as
4933 an experimental one it is distributed and thus should be documented and
4934 prepared for configuration the same way as all others modules.
4935 [Ralf S. Engelschall]
4937 *) Add query (-q) option to apxs support tool to be able to manually query
4938 specific settings from apxs. This is needed for instance when you
4939 manually want to access Apache's header files and you need to assemble
4940 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
4941 [Ralf S. Engelschall]
4943 *) Now src/Configure uses a fallback strategy for the shared object support
4944 on platforms where no explicit information is available: If a Perl
4945 installation exists we ask it about its shared object support and if it's
4946 the dlopen-style one we shamelessly guess the compiler and linker flags
4947 for creating shared objects from Perls knowledge. Of course, the user is
4948 warning about what we are doing and informed that he should send us
4949 the guessed flags when they work. [Ralf S. Engelschall]
4951 *) Provide APACI --without-support option to be able to disable the build
4952 and installation of the support tools from the src/support/ area.
4953 Although its useful to have these installed per default we should provide
4954 a way to compile and install without them for backward-compatibility.
4955 [Ralf S. Engelschall]
4957 *) Add of the new APache eXtenSion (apxs) support tool for building and
4958 installing modules into an _already installed_ Apache package through the
4959 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
4960 this approach actually doesn't need the Apache source tree. The
4961 (APACI-installed) server package is enough, because this now includes the
4962 Apache C header files (PREFIX/include) and the new APXS tool
4963 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
4964 module authors to build their Apache modules _OUTSIDE_ the Apache source
4965 tree while avoiding them to fiddle around with the totally platform
4966 dependend way of compiling DSO files. The tool supports all ranges of
4967 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
4968 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
4969 on-the-fly generate a minimalistic Makefile and sample module for the
4970 first step to provide both a quick success event and to demonstrate the
4971 APXS mechanism to module authors. [Ralf S. Engelschall]
4973 *) Fix core dumps in use of CONNECT in proxy.
4974 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
4976 *) Modify the log directives in httpd.conf-dist files to use CustomLog
4977 so that users have examples of how CustomLog can be used.
4980 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
4981 the Apache distribution tree. Until Apache 1.3 there was no real
4982 out-of-the-box batch-capable build and installation procedure for the
4983 complete Apache package. This is now provided by a top-level "configure"
4984 script and a corresponding top-level "Makefile.tmpl" file. The goal is
4985 to provide a GNU Autoconf-style frontend which is capable to both drive
4986 the old src/Configure stuff in batch and additionally installs the
4987 package with a GNU-conforming directory layout. Any options from the old
4988 configuration scheme are available plus a lot of new options for flexibly
4989 customizing Apache. [Ralf S. Engelschall]
4991 *) The floating point ap_snprintf code wasn't threadsafe.
4992 Had to remove the HAVE_CVT macro in order to do threadsafe
4993 calling of the ?cvt() floating point routines. [Dean Gaudet]
4995 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
4997 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
4998 [Jim Jagielski] PR#1901
5000 *) BUG: Configure was using TCC and CC inconsistently. Make sure
5001 Configure knows which CC we are using. [Jim Jagielski]
5003 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
5004 was defined in a parent directory. [Lars Eilebrecht]
5006 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
5007 a generic printf-style routine that can call arbitrary output
5008 routines. Use this to replace http_bprintf.c. Add new routines
5009 psprintf(), pvsprintf() which allocate the exact amount of memory
5010 required for a string from a pool. Use psprintf() to clean up
5011 various bits of code which used ap_snprintf()/pstrdup().
5014 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
5015 ap_snprintf() has different semantics and formatting codes than
5016 snprintf(). [Dean Gaudet]
5018 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
5019 is necessary on at least Solaris where the /etc/rc?.d scripts
5020 are run with these signals ignored, and "SIG_IGN" settings are
5021 maintained across exec().
5022 [Rein Tollevik <reint@sys.sol.no>] PR#2009
5024 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
5025 used instead of lstat() and thus this flag didn't work as expected.
5026 [Rein Tollevik <reint@sys.sol.no>] PR#2010
5028 *) Fix the proxy pass-through feature of mod_rewrite for the case of
5029 existing QUERY_STRING now that mod_proxy was recently changed because of
5030 the new URL parsing stuff. [Ralf S. Engelschall]
5032 *) A few changes to scoreboard definitions which helps gcc generate
5033 better code. [Dean Gaudet]
5035 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
5036 be a signed bitfield. So mark a few bitfields as signed to
5037 ensure correct code. [Dean Gaudet]
5039 *) The default for HostnameLookups was changed to Off, but there
5040 was a problem and it wasn't taking effect. [Dean Gaudet]
5042 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
5045 *) After a SIGHUP the listening sockets in the parent weren't
5046 properly marked for closure on fork().
5047 [Jürgen Keil <jk@tools.de>] PR#2000
5049 *) Allow %2F in two situations: 1) it is in the query part of the URI,
5050 therefore not exposed to %2F -> '/' translations and 2) the request
5051 is a proxy request, so we're not dealing with a local resource anyway.
5052 Without this, the proxy would fail to work for any URL's with
5053 %2f in them (occurs quite often in
5054 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
5056 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
5058 *) Make the shared object compilation command more portable by avoiding
5059 the direct combination of `-c' & `-o' which is not honored by some
5060 compilers like UnixWare's cc. [Ralf S. Engelschall]
5062 *) WIN32: the proxy was creating filenames missing the last four
5063 characters. While this normally doesn't stop anything from
5064 working, it can result in extra collisions.
5065 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
5067 *) Now mod_proxy uses the response string (in addition to the response status
5068 code) from the already used FTP SIZE command to setup the Content-Length
5069 header if available. [Ralf S. Engelschall] PR#1183
5071 *) Reanimated the (still undocumented) proxy receive buffer size directive:
5072 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
5073 name was really too generic, added documentation for this directive to
5074 the mod_proxy.html and corrected the hyperlink to it in the
5075 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
5077 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
5078 faster [Martin Kraemer]
5080 *) Make Configure die when you give it an unknown command switch.
5083 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
5084 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
5085 and per default compiled support programs have manual pages - just to
5086 document our stuff a little bit more and to be able to do really
5087 Unix-like installations ;-) [Ralf S. Engelschall]
5089 *) Major cleanups to the Configure script to make it and its generated
5090 Makefiles again readable and maintainable: add SRCDIR option, removed
5091 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
5092 generated sections, consequently added Makefile headers with inheritance
5093 information, added subdir movement messages for easier following where
5094 the build process currently stays (more verbose then standard Make, less
5095 verbose than GNU make), same style to comments in the Configure script,
5096 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
5098 *) Add the new ApacheBench program "ab" to src/support/: This is derived
5099 from the ZeusBench benchmarking program and can be used to determine the
5100 response performance of an Apache installation. This version is
5101 officially licensed with Zeus Technology, Ltd. See the license agreement
5102 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
5103 [Ralf S. Engelschall]
5105 *) API: Various core functions that are definately not part of the API
5106 have been made static, and a few have been marked API_EXPORT. Still
5107 more have been marked CORE_EXPORT and are not intended for general
5108 use by modules. [Doug MacEachern, Dean Gaudet]
5110 *) mod_proxy was not clearing the Proxy-Connection header from
5111 requests; now it does. This did not violate any spec, however
5112 causes poor interactions when you are talking to remote proxies.
5113 [Marc Slemko] PR#1741
5115 *) Various cleanups to the command line interface and manual pages.
5116 [Ralf S. Engelschall]
5118 *) cfg_getline() was not properly handling lines that did not end
5119 with a line termination character. [Marc Slemko] PR#1869, 1909
5121 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
5123 *) Clean up some undocumented behavior of mod_setenvif related to
5124 "merging" two SetEnvIf directives when they match the same header
5125 and regex. Document that mod_setenvif will perform comparisons in
5126 the order they appear in the config file. Optimize mod_setenvif by
5127 doing more work at config time rather than at runtime.
5130 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
5131 to allow for modules to overrule them and to reduce redefinition
5132 warnings [Jim Jagielski]
5134 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
5137 *) Making the hard-coded cross-module function call mime_find_ct() (from
5138 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
5139 checking is really called even for proxy requests except for URLs with
5140 HTTP schemes (because there we can optimize by not running the type
5141 checking hooks due to the fact that the proxy gets the MIME Content-type
5142 from the remote host later). This change cleans up mod_mime by removing
5143 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
5144 especially unbundles mod_proxy and mod_mime. This way they both now can
5145 be compiled as shared objects and are no longer tied together.
5146 [Ralf S. Engelschall]
5148 *) util.c cleanup and speedup. [Dean Gaudet]
5150 *) API: Clarification, pstrndup() will always copy n bytes of the source
5151 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
5153 *) Mark module command_rec and handler_rec structures const so that they
5154 end up in the read-only data section (and are friendlier to systems
5155 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
5157 *) Add check to the "Port" directive to make sure the specified
5158 port is in the appropriate range. [Ben Hyde]
5160 *) Performance improvements to invoke_handler().
5161 [Dmitry Khrustalev <dima@bog.msu.su>]
5163 *) Added support for building shared objects even for library-style modules
5164 (which are built from more than one object file). This now provides the
5165 ability to build mod_proxy as a shared object module. Additionally
5166 modules like mod_example are now also supported for shared object
5167 building because the generated Makefiles now no longer assume there is at
5168 least one statically linked module. [Ralf S. Engelschall]
5170 *) API: Clarify usage of content_type, handler, content_encoding,
5171 content_language and content_languages fields in request_rec. They
5172 must always be lowercased; and the strings pointed to shouldn't
5173 be modified (you must copy them to modify them). Fix a few bugs
5174 related to this. [Dean Gaudet]
5176 *) API: Clarification: except for RAW_ARGS, all command handlers can
5177 treat the char * parameters as permanent, and modifiable. There
5178 is no need to pstrdup() them. Clean up some needless pstrdup().
5181 *) Now mod_so keeps track of which module shared objects with which names
5182 are loaded and thus avoids multiple loading and unloading and irritating
5183 error_log messages. [Ralf S. Engelschall]
5185 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
5186 environment variable in the apache core. But that tweaking interferes
5187 with mod_setenv. So don't tweak if the user has specified an explicit
5188 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888

5196 [Tony Finch <fanf@demon.net>] PR#1925
5198 *) Various improvements to the configuration and build support for compiling
5199 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
5200 OSF1 support with GCC and vendor compilers was added. This way shared
5201 object support is now provided out-of-the-box for FreeBSD, Linux,
5202 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
5203 [Ralf S. Engelschall]
5205 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
5206 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
5207 and USE_OS2_SCOREBOARD. [Dean Gaudet]
5209 *) Fix one more special locking problem for RewriteMap programs in
5210 mod_rewrite: According to the documentation of flock(), "Locks are on
5211 files, not file descriptors. That is, file descriptors duplicated
5212 through dup(2) or fork(2) do not result in multiple instances of a lock,
5213 but rather multiple references to a single lock. If a process holding a
5214 lock on a file forks and the child explicitly unlocks the file, the
5215 parent will lose its lock.". To overcome this we have to make sure the
5216 RewriteLock file is opened _AFTER_ the childs were spawned which is now
5217 the case by opening it in the child_init instead of the module_init API
5218 hook. [Ralf S. Engelschall] PR#1029
5220 *) Change to Location and LocationMatch semantics. LocationMatch no
5221 longer lets a single slash match multiple adjacent slashes in the
5222 URL. This change is for consistency with RewriteRule and
5223 AliasMatch. Multiple slashes have meaning in URLs that they do
5224 not have in (some) filesystems. Location on the other hand can
5225 be considered a shorthand for a more complicated regex, and it
5226 does match multiple slashes with a single slash -- which is
5227 also consistent with the Alias directive.

5230 *) Fix bug with mod_mime_magic causing certain files, including files
5231 of length 0, to result in no response from the server.
5234 *) The Configure script now generates src/include/ap_config.h which
5235 contains the set of defines used when Apache is compiled on a platform.
5236 This file can then be included by external modules before including
5237 any Apache header files in case they are being built separately from
5238 Apache. Along with this change, a couple of minor changes were
5239 made to make Apache's #defines coexist peacefully with any autoconf
5240 defines an external module might have. [Rasmus Lerdorf]
5242 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
5243 but without any RewriteXXXXX directives. Here mod_rewrite is given no
5244 chance by the API to initialize its per-server configuration and thus
5245 receives the wrong one from the main server. This is now avoided by
5246 remembering the server together with the config structure while
5247 configuring and later assuming there is no config when we see a
5248 difference between the remembered server and the one calling us.
5249 [Ralf S. Engelschall] PR#1790
5251 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
5252 is automatically disabled under configure time when the dbm_xxx functions
5253 are not available. Second, two heavy source code errors in the DBM
5254 support code were fixed. This makes DBM RewriteMap's usable again after
5255 a long time of brokenness. [Ralf S. Engelschall] PR#1696
5257 *) Now all configuration files support Unix-style line-continuation via
5258 the trailing backslash ("\") character. This enables us to write down
5259 complex or just very long directives in a more readable way. The

5279 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
5280 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
5281 up static content only servers. Or it may fail unpredictably.

5284 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
5287 *) API: Rewrite of absoluteURI handling, and in particular how
5288 absoluteURIs match vhosts. Unless a request is a proxy request, a
5289 "http://host" url is treated as if a similar "Host:" header had been
5290 supplied. This change was made to support future HTTP/1.x protocols
5291 which may require clients to send absoluteURIs for all requests.
5293 In order to achieve this change subtle changes were made to the API. In a
5294 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
5295 that the unmodified uri can be retrieved easily. r->proxyreq is not set
5296 by the core, modules must set it during the post_read_request or
5297 translate_names phase.
5299 Plus changes to the virtualhost test suite for absoluteURI testing.
5301 This fixes several bugs with the proxy proxying requests to vhosts
5302 managed by the same httpd.

5325 parts. These parts are stored in a uri_components structure called
5326 parsed_uri within each request_rec, and are available to all modules.
5327 Additionally, an unparse routine is supplied which re-assembles the URI
5328 components back to an URI, optionally hiding the username:password@ part
5329 from ftp proxy requests, and other useful routines. Within the structure,
5330 you find on a ready-for-use basis:
5331 scheme; /* scheme ("http"/"ftp"/...) */
5332 hostinfo; /* combined [user[:password]@]host[:port] */
5333 user; /* user name, as in http://user:passwd@host:port/ */
5334 password; /* password, as in http://user:passwd@host:port/ */
5335 hostname; /* hostname from URI (or from Host: header) */
5336 port_str; /* port string (integer representation is in "port") */
5337 path; /* the request path (or "/" if only scheme://host was given) */
5338 query; /* Everything after a '?' in the path, if present */
5339 fragment; /* Trailing "#fragment" string, if present */
5340 This is meant to serve as the platform for *BIG* savings in
5341 code complexity for the proxy module (and maybe the vhost logic).
5344 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
5345 ${map:key}) available for all location where a string is created in
5346 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
5347 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
5348 possible expansions are consequently usable at all string creation
5349 locations. [Ralf S. Engelschall]
5351 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
5352 and not 1) and the per-virtual-server merging of directives. Now all
5353 directives except `RewriteEngine' and `RewriteOption' are either
5354 completely overridden (default) or completely inherited (when
5355 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325
5357 *) Fix `RewriteMap' program lookup in situations where such maps are
5358 defined but disabled (`RewriteEngine off') in per-server context.
5359 [Ralf S. Engelschall] PR#1431
5361 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause
5362 server to bind to port 0 rather than 80. [Dean Gaudet]
5364 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
5365 (like SunOS and FreeBSD) which don't accept the locking of pipes
5366 directly. A new directive RewriteLock is introduced which can be used to
5367 setup a separate locking file which then is used for synchronization.
5368 [Ralf S. Engelschall] PR#1029
5370 *) WIN32: The server root is obtained from the registry key
5371 HKLM\SOFTWARE\Apache Group\Apache\<version> (version is currently
5372 "1.3 beta"), unless overridden by the -d command line flag. The
5373 value is stored by running "apache -i -d serverroot". [Paul Sutton]
5375 *) Merged os/win32/mod_dll.c into modules/standard/mod_so.c to support
5376 dynamic loading on Win32 and Unix via the same module. [Paul Sutton]

5379 a username can contain when trying to expand it via /etc/passwd.

5382 *) The mod_setenvif BrowserMatch backwards compatibility command did not
5383 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
5385 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
5386 type but with a special post-processing for the looked-up value: It
5387 parses it into alternatives according to `|' chars and then only one
5388 particular alternative is chosen randomly (this is an essential
5389 functionality needed for balancing between backend-servers when using
5390 Apache as a Reverse Proxy. The looked up value here is a list of
5391 servers). Second, `int' with the built-in maps named `tolower' and
5392 `toupper' which can be used to map URL parts to a fixed case (this is an
5393 essential feature to fix the case of server names when doing mass
5394 virtual-hosting with the help of mod_rewrite instead of using
5395 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
5396 Jay Soffian <jay@cimedia.com>] PR#1631
5398 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
5399 This directive lets Apache adjust the URL in Location-headers on HTTP
5400 redirect responses sent by the remote server. This way the virtually
5401 mapped area is no longer left on redirects and thus by-passed which is
5402 especially essential when running Apache as a reverse proxy.
5403 [Ralf S. Engelschall]
5405 *) Hide Proxy-Authorization from CGI/SSI/etc just like Authorization is
5406 hidden. [Alvaro Martinez Echevarria]
5408 *) Apache will, when started with the -X (single process) debugging flag,
5409 honor the SIGINT or SIGQUIT signals again now. This capability got lost
5410 a while ago during OS/2 signal handling changes.
5412 *) [PORT] Work around the fact that NeXT runs on more than the
5413 m68k chips in mod_status [Scott Anguish and Timothy Luoma

5420 *) Use SA_RESETHAND or SA_ONESHOT when installing the coredump handlers.
5421 In particular the handlers could trigger themselves into an infinite
5422 loop if RLimitMem was used with a small amount of memory -- too small
5423 for the signal stack frame to be set up. [Dean Gaudet]

5435 defines are non-static now so modules can use 'em. [Martin Kraemer]
5437 *) mod_info would occasionally produce an unpaired <tt> in its
5438 output. Fixed. [Martin Kraemer]
5440 *) By default AIX binds a process (and it's children) to a single
5441 processor. httpd children now unbind themselves from that cpu
5442 and re-bind to one selected at random via bindprocessor()
5445 *) Linux 2.0 and above implement RLIMIT_AS, RLIMIT_DATA has almost no
5446 effect. Work around it by using RLIMIT_AS for the RLimitMEM
5447 directive. [Enrik Berkhan <enrik@inka.de>] PR#1816
5449 *) mod_mime_magic error message should indicate the filename when
5450 reads fail. ["M.D.Parker" <mdpc@netcom.com>] PR#1827
5452 *) Previously Apache would permit </Files> to end <FilesMatch> (and
5453 similary for Location and Directory), now this is diagnosed as an
5454 error. Improve error messages for mismatched sections (<Files>,
5455 <FilesMatch>, <Directory>, <DirectoryMatch>, ...).
5456 [Dean Gaudet, Martin Kraemer]
5458 *) <Files> is not permitted within <Location> (because of the
5459 semantic ordering). [Dean Gaudet] PR#379
5461 *) <Files> with wildcards was broken by the change in wildcard
5462 semantics (* does not match /). To fix this, <Files> now
5463 apply only to the basename of the request filename. This
5464 fixes some other inconsistencies in <Files> semantics
5465 (such as <Files a*b> not working). [Dean Gaudet] PR#1817
5467 *) Removed bogus "dist.tar" target from Makefile.tmpl and make sure
5468 backup files are removed on "clean" target [Ralf S. Engelschall]

5472 *) Various errors from select() and accept() in child_main() would
5473 result in an infinite loop. It seems these two tickle kernel
5474 or library bugs occasionally, and result in log spammage and
5475 a generally bad scene. Now the child exits immediately,

5490 Changes with Apache 1.3b5
5492 *) Source file dependencies in Makefile.tmpl files throughout the

5496 *) Preserve the content encoding given by the AddEncoding directive
5497 when the client doesn't otherwise specify an encoding.

5500 *) Sort out problems with canonical filename handling happening too late.
5501 [Dean Gaudet, Ben Laurie]
5503 Changes with Apache 1.3b4
5505 *) The module structure was modified to include a *dynamic_load_handle
5506 in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
5507 has been bumped accordingly. [Paul Sutton]
5509 *) All BrowserMatch directives mentioned in
5510 htdocs/manual/known_client_problems.html are in the default
5511 configuration files. [Lars Eilebrecht]
5513 *) MiNT port update. [Jan Paul Schmidt]
5515 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
5516 equivalent, similarly for x-compress and compress. Apache
5517 now ignores a leading x- when comparing encodings. It also
5518 preserves the encoding the client requests (for example if
5519 it requests x-gzip, then Apache will respond with x-gzip
5520 in the Content-Encoding header).
5521 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1772
5523 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
5525 *) Added mod_so module to support dynamic loading of modules on Unix
5526 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
5527 instead of AddModule in Configuration to build shared modules
5528 [Sameer Parekh, Paul Sutton]
5530 *) Minor cleanups to r->finfo handling in some modules.
5533 *) Abstract read()/write() to ap_read()/ap_write().
5534 Makes it easier to add other types of IO code such as SFIO.
5537 *) API: Generalize default_port manipulations to make support of
5538 different protocols easier. [Ben Laurie, Randy Terbush]
5540 *) There are many cases where users do not want Apache to form
5541 self-referential urls using the "canonical" ServerName and Port.
5542 The new UseCanonicalName directive (default on), if set to off
5543 will cause Apache to use the client-supplied hostname and port.
5544 API: Part of this change required a change to the construct_url()
5545 prototype; and the addition of get_server_name() and
5547 [Michael Douglass <mikedoug@texas.net>, Dean Gaudet]
5548 PR#315, 459, 485, 1433
5550 *) Yet another rearrangement of the source tree.. now all the common
5551 header files are in the src/include directory. The -Imain -Iap
5552 references in Makefiles have been changed to the simpler -Iinclude
5553 instead. In addition to simplifying the build a little bit, this
5554 also makes it clear when a module is referencing something in a
5555 other than kosher manner (e.g., the proxy including mod_mime.h).
5556 Module-private header files (the proxy, mod_mime, the regex library,
5557 and mod_rewrite) have not been moved to src/include; nor have
5558 the OS-abstraction files. [Ken Coar]
5560 *) Fix a bug where r->hostname didn't have the :port stripped
5561 from it. [Dean Gaudet]
5563 *) Tweaked the headers_out table size, and the subprocess_env
5564 table size guess in rename_original_environment(). Added
5565 MAKE_TABLE_PROFILE which can help discover make_table()
5566 calls that use too small an initial guess, see alloc.c.
5569 *) Options and AllowOverride weren't properly merging in the main
5570 server setting inside vhosts (only an issue when you have no
5571 <Directory> or other section containing an Options that affects
5572 a request). Options +foo or -foo in the main_server wouldn't
5573 affect the main_server's lookup defaults. [Dean Gaudet]
5575 *) Variable 'cwd' was being used pointlessly before being set.
5578 *) r->allowed handling cleaned up in the standard modules.
5581 *) Some case-sensitivity issues cleaned up to be consistent with
5582 RFC2068. [Dean Gaudet]
5584 *) SIGURG doesn't exist everywhere.
5585 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
5587 *) mod_unique_id was erroneously generating a second unique id when
5588 an internal redirect occured. Such redirects occur, for example,
5589 when processing a DirectoryIndex match. [Dean Gaudet]
5591 *) API: table_add, table_merge, and table_set include implicit pstrdup()
5592 of the key and value. But in many cases this is not required
5593 because the key/value is a constant, or the value has been built
5594 by pstrcat() or other similar means. New routines table_addn,
5595 table_mergen, and table_setn have been added to the API, these
5596 routines do not pstrdup() their arguments. The core code and
5597 standard modules were changed to take advantage of these routines.
5598 The resulting server is up to 20% faster in some situations.
5600 Note that it is easy to get code subtly wrong if you pass a key/value
5601 which is in a pool other than the pool of the table. The only
5602 safe thing to do is to pass key/values which are in the pool of
5603 the table, or in one of the ancestors of the pool of the table.
5604 i.e. if the table is part of a subrequest, a value from the main
5605 request's pool is OK since the subrequest pool is a sub_pool of the
5606 main request's pool (and therefore has a lifespan at most as long as
5607 the main pool). There is debugging code which can detect improper
5608 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
5609 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
5611 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
5612 which don't exist on disk more gracefully; handles vhosts properly.
5613 Update documentation to reflect the code -- if there's no
5614 MimeMagicFile directive then the module is not enabled.
5617 *) PORT: Some older *nix dialects cannot automatically start scripts
5618 which begin with a #! interpreter line (the shell starts the scripts
5619 appropriately on these platforms). Apache now supports starting of
5620 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
5621 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
5624 *) API: "typedef array_header table" removed from alloc.h, folks should
5625 have been writing to use table as if it were an opaque type, but even
5626 some standard modules got this wrong. By changing the definition
5627 to "typedef struct table table" module authors will receive compile
5628 time warnings that they're doing the wrong thing. This change
5629 facilitates future changes with more sophisticated table
5630 structures. Specifically, module authors should be using table_elts()
5631 to get access to an array_header * for the table. [Dean Gaudet]
5633 *) API: Renamed new_connection() to avoid namespace collision with LDAP
5634 library routines. [Ken Coar, Rasmus Lerdorf]
5636 *) WIN32: mod_speling is now available on the Win32 platform.
5639 *) For clarity the following compile time definition was changed:
5641 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
5643 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
5644 and not be a general notice that the OS has mmap(). Now the
5645 HAVE_MMAP/SHMGET #defines strictly are informational that the
5646 OS has that method of shared memory; the type to use for
5647 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
5648 and USE_SHMGET_SCOREBOARD). This allows outside modules to
5649 determine if shared memory is available and allows Apache
5650 to determine the best method to use for the scoreboard.
5653 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
5654 as do various earlier versions. It should be safe on all versions.
5655 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
5656 the slack code. A few other cleanups for Unixware.

5659 *) PORT: A/UX can handle single-listen accepts without mutex
5660 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
5662 *) When die() happens we need to eat any request body if one exists.
5663 Otherwise we can't continue with a keepalive session. This shows up
5664 as a POST problem with MSIE 4.0, typically against pages which are
5665 authenticated. [Roy Fielding] PR#1399
5667 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
5668 header will be passed to CGIs. This is generally a security hole, so
5669 it's not a default. [Marc Slemko] PR#549

5676 *) suexec errors now include the errno/description. [Marc Slemko] PR#1543
5678 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
5679 The choice of flock vs. fcntl was made based on timings which showed that
5680 even on non-NFS, non-exported filesystems fcntl() was an order of
5681 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
5682 that single socket users will see no difference. [Dean Gaudet] PR#467
5684 *) "File does not exist" error message was erroneously including the
5685 errno. [Marc Slemko]
5687 *) Improve the warning message generated when a client drops the
5688 connection (hits stop button, etc.) during a send. [Roy Fielding]
5690 *) Defining GPROF will disable profiling in the parent and enable it

5692 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
5694 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.

5704 *) Some const declarations in mod_imap.c that were added for debugging
5705 purposes caused some compilers heartburn without adding any
5706 significant value, so they've been removed. [Ken Coar]
5708 *) The src/main/*.h header files have had #ifndef wrappers added to
5709 insulate them against duplicate calls if they get included through
5710 multiple paths (e.g., in .c files as well as other .h files).
5713 *) The libap routines now have a header file for their prototypes,
5714 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
5716 *) mod_autoindex with a plaintext header file would emit the <PRE>
5717 start-tag before the HTML preamble, rather than after the preamble
5718 but before the header file contents. [John Van Essen <jve@gamers.org>]
5721 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
5722 only an issue on systems without a MAXDNAME define or where
5723 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
5725 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
5726 is used to read various types of files such as htaccess and
5727 htpasswd files. [Marc Slemko]
5729 *) SECURITY: Ensure that the buffer returned by ht_time is always
5730 properly null terminated. [Marc Slemko]
5732 *) The "Connection" header could be sent back with multiple "close"
5733 tokens. Not an error, but a waste.
5734 [Ronald.Tschalaer@psi.ch] PR#1683
5736 *) mod_rewrite's RewriteLog should behave like mod_log_config, it

5739 *) "basic" auth needs a case-insensitive comparison.
5740 [Ronald.Tschalaer@psi.ch] PR#1666
5742 *) For maximum portability, the environment passed to CGIs should
5743 only contain variables whose names match the regex
5744 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
5745 underscores over any character outside the regex. This
5746 affects HTTP_* variables, in a way that should be backward
5747 compatible for all the standard headers; and affects variables
5748 set with SetEnv/BrowserMatch and similar directives.

5839 bogus chunked output. (Typically this will show up as problems
5840 with Internet Explorer 4.0 reading a page, but other browsers
5841 having no problem.) [Dean Gaudet]
5843 *) Create LARGE_WRITE_THRESHOLD define which determines how many
5844 bytes have to be supplied to bwrite() before it will consider
5845 doing a writev() to assemble multiple buffers in one system
5846 call. This is critical for modules such as mod_include,
5847 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
5848 strings in some cases. The result would be extra effort
5849 setting up writev(), and in many cases extra effort building
5850 chunks. The default is 31, it can be overriden at compile
5853 *) Move the gid switching code into the child so that log files
5854 and pid files are opened with the root gid.

5858 instead of counting control characters.
5859 [Jim Patterson <Jim.Patterson@Cognos.COM>] PR#1340
5861 *) ap_snprintf() moved from main/util_snprintf.c to ap/ap_snprintf.c
5862 so the functionality is available to applications other than the
5863 server itself (like the src/support tools). [Ken Coar]
5865 *) ap_slack() moved out of main/util.c into ap/ap_slack.c as part of
5866 the libap consolidation work. [Ken Coar]
5868 *) ap_snprintf() with a len of 0 behaved like sprintf(). This is not
5869 useful, and isn't what the standards require. Now it returns 0
5870 and writes nothing. [Dean Gaudet]

5878 *) mod_autoindex had an fread() without checking the result code.
5879 It also wouldn't handle "AddIconByType (TXT,/icons/text.gif text/*"

5882 *) It appears the "257th byte" bug (see

5960 This turns out to be a bug in Winsock - select() doesn't always
5961 return the correct status. [Ben Laurie]
5963 *) Directives owned by http_core can now use the new check_cmd_context()
5964 routine to ensure that they're not being used within a container
5965 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
5967 *) PORT: Recent changes made it necessary to add explicit prototype
5968 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
5970 *) It was necessary to distinguish between resources which are
5971 allocated in the parent, for cleanup in the parent, and resources
5972 which are allocated in each child, for cleanup in each child.
5973 A new pool was created which is passed to the module child_init
5974 and child_exit functions; modules are free to register per-child
5975 cleanups there. This fixes a bug with reliable piped logs.
5978 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
5979 unless it was also doing FancyIndexes, but it displayed the
5980 HeaderName file at the top under all circumstances. It now shows
5981 the ReadmeName file for simple indices, too, as it should.
5984 *) http_core was mmap()ing even in cases where it wasn't going to
5985 read the file. [Ben Hyde <bhyde@gensym.com>]
5987 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
5988 Now the rewriting engine (the heart of mod_rewrite) is organized more
5989 straight-forward, first time well documented and reduced to the really
5990 essential parts. All redundant cases were stripped off and processing now
5991 is the same for both per-server and per-directory context with only a
5992 minimum difference (the prefix stripping in per-dir context). As a
5993 side-effect some subtle restrictions and two recently discovered problems
5994 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
5995 context and restrictions on the substitution URL on redirects.
5996 Additionally some minor source cleanups were done.

6153 *) TestCompile was not passing $LIBS [Dean Gaudet]
6155 *) Makefile.tmpl was not using $CFLAGS in the link phase.
6158 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
6159 rudimentary memory debugger which can be used on live servers with
6160 low impact -- it sets all allocated and freed memory bytes to 0xa5.
6161 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
6162 and free() for each object. This is far more expensive and should
6163 only be used for testing with tools such as Electric Fence and
6164 Purify. See main/alloc.c for more details. [Dean Gaudet]
6166 *) Configure uses a sh trap and didn't set its exitcode properly.
6167 [Dean Gaudet] PR#1159
6169 *) Yet another vhost revamp. Add the NameVirtualHost directive which
6170 explicitly lists the ip:port pairs that are to be used for name-vhosts.
6171 From a given ip:port, regardless what the Host: header is, you can
6172 only reach the vhosts defined on that ip:port. The precedence of
6173 vhosts was reversed to match other precedences in the config --
6174 the earlier vhosts override the later vhosts. All vhost matching was
6175 moved into http_vhost.[ch]. [Dean Gaudet]
6177 *) ap_inline can be used to force inlining. GNUC __attribute__() can
6178 be used for whatever reason is appropriate (i.e. format() warnings
6179 for printf style functions). Both are enabled only with
6180 gcc >= 2.7.x (so that we have fewer support issues with older
6181 versions). [Dean Gaudet]
6183 *) Fix support for Proxy Authentication (we were testing the response
6184 status too early). [Marc Slemko]
6186 *) CoreDumpDirectory directive directs where the core file is

6193 *) When booting, apache will now detach itself from stdin, stdout,
6194 and stderr. stderr will not be detached until after the config
6195 files have been read so you will be able to see initial error
6196 messages. After that all errors are logged in the error_log.
6197 This makes it more convenient to start apache via rsh, ssh,
6198 or crontabs. [Dean Gaudet] PR#523
6200 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.

6212 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
6214 *) mod_autoindex improperly counted &escapes; as more than one
6215 character in the description. It also improperly truncated
6216 descriptions that were exactly the maximum length.
6219 *) RedirectMatch was not properly escaping the result (PR#1155). Also
6220 "RedirectMatch /advertiser/(.*) $1" is now permitted.
6223 *) mod_include now uses symbolic names to check for request success
6224 and return HTTP errors, and correctly handles all types of
6225 redirections (previously it only did temporary redirect correctly).
6226 [Ken Coar, Roy Fielding]
6228 *) mod_userdir was modifying r->finfo in cases where it wasn't setting

6242 *) Fixed error in proxy_util.c when looping through multiple host IP

6245 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
6246 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
6247 bytes before writing, but it will never split a log entry across a
6248 buffer boundary. [Dean Gaudet]
6250 *) API: the short_score record has been split into two pieces, one which
6251 the parent writes on, and one which the child writes on. As part of
6252 this change the get_scoreboard_info() function was removed, and
6253 scoreboard_image was exported. This change fixes a race condition
6254 in file based scoreboard systems, and speeds up changes involving the
6255 scoreboard in earlier 1.3 development. [Dean Gaudet]
6257 *) API: New register_other_child() API (see http_main.h) which allows
6258 modules to register children with the parent for maintenance. It
6259 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
6261 *) API: New piped_log API (see http_log.h) which implements piped logs,
6262 and will use register_other_child to implement reliable piped logs
6263 when it is available. The reliable piped logs part can be disabled
6264 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
6265 logs is only available on Unix. [Dean Gaudet]
6267 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
6268 meets_conditions(). This allows conditional HTTP selection to be
6269 handled separately from the storing of the header fields, and provides
6270 the ability for CGIs to set their own ETags for conditional checking.

6278 *) New module, "mod_speling", which can help find files even when
6279 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
6281 *) API: New function child_terminate() triggers the child process to
6282 exit, while allowing the child finish what it needs to for the
6283 current request first.

6289 *) *Really* disable all mod_rewrite operations if the engine is off.
6290 Some things (like RewriteMaps) were checked/performed even if they
6291 weren't supposed to be. [Ken Coar] PR #991
6293 *) Implement a new timer scheme which eliminates the need to call alarm() all
6294 the time. Instead a counter in the scoreboard for each child is used to
6295 show when the child has made forward progress. The parent samples this
6296 counter every scoreboard maintenance cycle, and issues SIGALRM if no
6297 progress has been made in the timeout period. This reduces the static
6298 request best-case syscall count to 22 from 29. This scheme is only
6299 used by systems with memory-based scoreboards. [Dean Gaudet]
6301 *) The proxy now properly handles CONNECT requests which are sent
6302 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
6304 *) A script called apachectl has been added to the support
6305 directory. This script allows you to do things such as
6306 "apachectl start" and "apachectl restart" from the command
6309 *) Modules and core routines are now put into libraries, which
6310 simplifies the link line tremendously (among other advantages).
6313 *) Some of the MD5 names defined in Apache have been renamed to have
6314 an `ap_' prefix to avoid conflicts with routines supplied by
6315 external libraries. [Ken Coar]
6317 *) Removal of mod_auth_msql.c from the distribution. There are many
6318 other options for databases today. Rather than offer one option,
6319 offer none at this time. mod_auth_msql and other SQL database
6320 authentication modules can be found at the Apache Module Registry.
6321 http://modules.apache.org/ It would be nice to offer a generic
6322 mod_auth_sql option in the near future.
6324 *) PORT: BeOS support added [Alexei Kosut]
6326 *) Configure no longer accepts the -make option, since it creates
6327 Makefile on the fly based on Makefile.tmpl and Configuration.
6329 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
6330 of forcibly killing off all its processes and exiting without
6331 cleaning up. [Alexei Kosut]
6333 *) API: A new field in the request_rec, r->mtime, has been added to
6334 avoid gratuitous parsing of date strings. It is intended to hold
6335 the last-modified date of the resource (if applicable). An
6336 update_mtime() routine has also been added to advance it if
6337 appropriate. [Roy Fielding, Ken Coar]
6339 *) SECURITY: If a htaccess file can not be read due to bad permissions,
6340 deny access to the directory with a HTTP_FORBIDDEN. The previous
6341 behavior was to ignore the htaccess file if it could not be read.
6342 This change may make some setups with unreadable htaccess files
6343 stop working. [Marc Slemko] PR#817
6345 *) Add aplog_error() providing a mechanism to define levels of
6346 verbosity to the server error logging. This addition also provides
6347 the ability to log errors using syslogd. Error logging is configurable
6348 on a per-server basis using the LogLevel directive. Conversion
6349 of log_*() in progress. [Randy Terbush]

6364 configured and running" entry in the error_log. Also build an
6365 object file at link-time that contains the current time
6366 (SERVER_BUILT global const char[]), and include that in the
6369 *) Set r->headers_out when sending responses from the proxy.
6370 This fixes things such as the logging of headers sent from
6371 the proxy. [Marc Slemko] PR#659
6373 *) support/httpd_monitor is no longer distributed because the
6374 scoreboard should not be file based if at all possible. Use
6375 mod_status to see current server snapshot.
6377 *) (set_file_slot): New function, allowing auth directives to be
6378 independent of the server root, so the server documents can be
6379 moved to a different directory or machine more easily.
6380 [David J. MacKenzie]
6382 *) If no TransferLog is given explicitly, decline
6383 to log. This supports coexistence with other logging modules,
6384 such as the custom one that UUNET uses. [David J. MacKenzie]
6386 *) Check for titles in server-parsed HTML files.
6387 Ignore leading newlines and returns in titles. The old behavior
6388 of replacing a newline after <title> with a space causes the
6389 title to be misaligned in the listing. [David J. MacKenzie]
6391 *) Change mod_cern_meta to be configurable on a per-directory basis.
6392 [David J. MacKenzie]
6394 *) Add 'Include' directive to allow inclusion of configuration
6395 files within configuration files. [Randy Terbush]
6397 *) Proxy errors on connect() are logged to the error_log (nothing
6398 new); now they include the IP address and port that failed
6399 (*that's* new). [Ken Coar, Marc Slemko] PR#352
6401 *) Various architectures now define USE_MMAP_FILES which causes
6402 the server to use mmap() for static files. There are two
6403 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
6404 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
6405 number of bytes written in one cycle from a single mmap()d object,
6406 default 32768). [Dean Gaudet]
6408 *) API: Added post_read_request API phase which is run right after reading
6409 the request from a client, or right after an internal redirect. It is
6410 useful for modules setting environment variables that depend only on
6411 the headers/contents of the request. It does not run during subrequests
6412 because subrequests inherit pretty much everything from the main
6413 request. [Dean Gaudet]
6415 *) Added mod_unique_id which is used to generate a unique identifier for
6416 each hit, available in the environment variable UNIQUE_ID.
6419 *) init_modules is now called after the error logs have been opened. This
6420 allows modules to emit information messages into the error logs.
6423 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
6424 information for case where proxy module is not available. [Marc Slemko]
6426 *) PORT: Apache has need for mutexes to serialize its children around
6427 accept. In prior versions either fcntl file locking or flock file
6428 locking were used. The method is chosen by the definition of
6429 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
6430 and FLOCK for flock(). New options have been added:
6431 - SYSVSEM to use System V style semaphores
6432 - PTHREAD to use POSIX threads (appears to work on Solaris only)
6433 - USLOCK to use IRIX uslock
6434 Based on timing various techniques, the following changes were made
6436 - Linux 2.x uses flock instead of fcntl
6437 - Solaris 2.x uses pthreads
6438 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
6439 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
6440 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
6441 Martijn Koster <m.koster@pobox.com>]
6443 *) PORT: The semantics of accept/select make it very desirable to use
6444 mutexes to serialize accept when multiple Listens are in use. But
6445 in the case where only a single socket is open it is sometimes
6446 redundant to serialize accept(). Not all unixes do a good job with
6447 potentially dozens of children blocked on accept() on the same
6448 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
6449 the server will avoid serialization when listening on only one socket,
6450 and use serialization when listening on multiple sockets.
6451 [Dean Gaudet] PR#467
6453 *) Configure changes: TestLib replaced by TestCompile, which has
6454 some additional capability (such as doing a sanity check of
6455 the compiler and flags selected); the version of Solaris is now
6456 available via the #define value of SOLARIS2; IRIX n32bit libs
6457 now supported and selectable by new Configuration Rule: IRIXN32;
6458 We no longer default to -O2 optimization. [Jim Jagielski]
6460 *) Updated Configure: Configuration now uses AddModule to specify
6461 module source or binary file location, relative to src directory.
6462 Modules can be dropped into modules/extra, or in their own
6463 directory, and modules can come with a Makefile or Configure can
6464 create one. Modules can add compiler or library information to
6465 generated Makefiles. [Paul Sutton]
6467 *) Source core re-organisation: distributed modules are now in
6468 modules/standard. All other source code is in main. OS-specific
6469 code is in os/{unix,emx,win32} directories. [Paul Sutton]
6471 *) mod_browser has been removed, since it's replaced by mod_setenvif.
6474 *) Fix another long-standing bug in sub_req_lookup_file where it would
6475 happily skip past access checks on subdirectories looked up with
6476 relative paths. (It's used by mod_dir, mod_negotiation,
6477 and mod_include.) [Dean Gaudet]
6479 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
6480 N is the number of <Directory> sections, and M is the number of
6481 components in the filename of an object.
6483 To achieve this optimization the following config changes were made:
6484 - Wildcards (* and ?, not the regex forms) in <Directory>s,
6485 <Files>s, and <Location>s now treat a slash as a special
6486 character. For example "/home/*/public_html" previously would
6487 match "/home/a/andrew/public_html", now it only matches things
6488 like "/home/bob/public_html". This mimics /bin/sh behaviour.
6489 - It's possible now to use [] wildcarding in <Directory>, <Files>
6491 - Regex <Directory>s are applied after all non-regex <Directory>s.
6495 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
6496 and corrupted paths. [Dean Gaudet]
6498 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
6499 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
6500 be accessed now via backreferences $1..$9 in RewriteConds test-against
6501 strings in addition to RewriteRules subst string. Second the grouped
6502 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
6503 via backreferences %1..%9 both in following RewriteCond test-against
6504 strings and RewriteRules subst string. This provides maximum flexibility
6505 through the use of backreferences.
6506 Additionally the rewriting engine was cleaned up by putting common
6507 code to the new expand_backrefs_inbuffer() function.
6508 [Ralf S. Engelschall]
6510 *) When merging the main server's <Directory> and <Location> sections into
6511 a vhost, put the main server's first and the vhost's second. Otherwise
6512 the vhost can't override the main server. [Dean Gaudet] PR#717
6514 *) The <Directory> code would merge and re-merge the same section after
6515 a match was found, possibly causing problems with some modules.
6518 *) ip-based vhosts are stored and queried using a hashing function, which
6519 has been shown to improve performance on servers with many ip-vhosts.
6520 Some other changes had to be made to accommodate this:
6521 - the * address for vhosts now behaves like _default_
6522 - the matching process now is:
6523 - match an ip-vhost directly via hash (possibly matches main
6525 - if that fails, just pretend it matched the main server
6526 - if so far only the main server has been matched, perform
6527 name-based lookups (ServerName, ServerAlias, ServerPath)
6528 *only on name-based vhosts*
6529 - if they fail, look for _default_ vhosts
6530 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
6532 *) dbmmanage overhaul:
6533 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
6534 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
6535 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
6536 - provide better seed for rand
6537 - prompt for password as per getpass(3) (turn off echo, read from
6539 - use "newstyle" crypt based on $Config{osname} ($^O)
6540 - will not add a user if already in database, use new `update' command
6542 - added `check' command to check a users' password
6543 - added `import' command to convert existing password text-files or
6544 dbm files exported with `view'
6545 - more descriptive usage, general cleanup, 'use strict' clean, etc.
6548 *) Added psocket() which is a pool form of socket(), various places within
6549 the proxy weren't properly blocking alarms while registering the cleanup
6550 for its sockets. bclose() now uses pclose() and pclosesocket(). There
6551 was a bug where the client socket was being close()d twice due a still
6552 registered cleanup. [Dean Gaudet]
6554 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
6557 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
6558 [Jason Venner <jason@idiom.com>] PR#667
6560 *) Enable ``=""'' for RewriteCond directives to match against
6561 the empty string. This is the preferred way instead of ``^$''.
6562 [Ralf S. Engelschall]
6564 *) Fixed an infinite loop in mod_imap for references above the server root
6565 [Dean Gaudet] PR#748
6567 *) mod_proxy now has a ReceiveBufferSize directive, similar to
6568 SendBufferSize, so that the TCP window can be set appropriately
6569 for LFNs. [Phillip A. Prindeville]
6571 *) mod_browser has been replaced by the more general mod_setenvif
6572 (courtesy of Paul Sutton). BrowserMatch* directives are still
6573 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
6574 UnSetEnvIfZero directives. [Ken Coar]
6576 *) "HostnameLookups double" forces double-reverse DNS to succeed in
6577 order for remote_host to be set (for logging, or for the env var
6578 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
6581 *) mod_access overhaul:
6582 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
6583 and cidr syntax (i.e. 10.1.0.0/16). PR#762
6584 - Critical path was sped up by pre-computing a few things at config time.
6585 - The undocumented syntax "allow user-agents" was removed,
6586 the replacement is "allow from env=foobar" combined with mod_browser.
6587 - When used with hostnames it now forces a double-reverse lookup
6588 no matter what the directory settings are. This double-reverse
6589 doesn't affect any of the other routines that use the remote
6590 hostname. In particular it's still passed to CGIs and the log
6591 without the double-reverse check. Related PR#860.
6594 *) When a large bwrite() occurs (larger than the internal buffer size),
6595 while there is already something in the buffer, apache will combine
6596 the large write and the buffer into a single writev(). (This is
6597 in anticipation of using mmap() for reading files.)
6600 *) In obscure cases where a partial socket write occurred while chunking,
6601 Apache would omit the chunk header/footer on the next block. Cleaned
6602 up other bugs/inconsistencies in error conditions in buff.c. Fixed
6603 a bug where a long pause in DNS lookups could cause the last packet
6604 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
6606 *) API: Added child_exit function to module structure. This is called
6607 once per "heavy-weight process" just before a server child exit()'s
6608 e.g. when max_requests_per_child is reached, etc.
6609 [Doug MacEachern, Dean Gaudet]
6611 *) mod_include cleanup showed that handle_else was being used to handle
6612 endif. It didn't cause problems, but it was cleaned up too.
6615 *) mod_cern_meta would attempt to find meta files for the directory itself
6616 in some cases, but not in others. It now avoids it in all cases.
6619 *) mod_mime_magic would core dump if there was a decompression error.
6620 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
6622 *) PORT: some variants of DGUX require -lsocket -lnsl
6623 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
6625 *) mod_autoindex now allows sorting of FancyIndexed directory listings
6626 by the various fields (name, size, et cetera), either in ascending
6627 or descending order. Just click on the column header. [Ken Coar]
6629 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
6630 CPUs like the Alpha. Apache still stores ints in pointers, but that's
6631 the relatively safe direction. [Dean Gaudet] PR#344
6633 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
6634 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
6636 *) child_main avoids an unneeded call to select() when there is only one
6637 listening socket. [Dean Gaudet]
6639 *) In the event that the server is starved for idle servers it will
6640 spawn 1, then 2, then 4, ..., then 32 servers each second,
6641 doubling each second. It'll also give a warning in the errorlog
6642 since the most common reason for this is a poor StartServers
6643 setting. The define MAX_SPAWN_RATE can be used to raise/lower
6644 the maximum. [Dean Gaudet]
6646 *) Apache now provides an effectively unbuffered connection for
6647 CGI scripts. This means that data will be sent to the client
6648 as soon as the CGI pauses or stops output; previously, Apache would
6649 buffer the output up to a fixed buffer size before sending, which
6650 could result in the user viewing an empty page until the CGI finished
6651 or output a complete buffer. It is no longer necessary to use an
6652 "nph-" CGI to get unbuffered output. Given that most CGIs are written
6653 in a language that by default does buffering (e.g. perl) this
6654 shouldn't have a detrimental effect on performance.
6656 "nph-" CGIs, which formerly provided a direct socket to the client
6657 without any server post-processing, were not fully compatible with
6658 HTTP/1.1 or SSL support. As such they would have had to implement
6659 the transport details, such as encryption or chunking, in order
6660 to work properly in certain situations. Now, the only difference
6661 between nph and non-nph scripts is "non-parsed headers".
6662 [Dean Gaudet, Sameer Parekh, Roy Fielding]
6664 *) If a BUFF is switched from buffered to unbuffered reading the first
6665 bread() will return whatever remained in the buffer prior to the
6666 switch. [Dean Gaudet]
6668 Changes with Apache 1.3a1
6670 *) Added another Configure helper script: TestLib. It determines
6671 if a specified library exists. [Jim Jagielski]
6673 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
6674 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
6677 *) PORT: Some architectures use size_t for various lengths in network
6678 functions such as accept(), and getsockname(). The definition
6679 NET_SIZE_T is used to control this. [Dean Gaudet]
6681 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
6682 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
6683 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
6685 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
6686 [Igor N Kovalenko <infoh@mail.wplus.net>]
6688 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
6689 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
6690 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
6691 [Dean Gaudet] related PR#875
6693 *) API: Correct child_init() slot declaration from int to void, to
6694 match the init() declaration. Update mod_example to use the new
6697 *) added transport handle slot (t_handle) to the BUFF structure
6700 *) get_client_block() returns wrong length if policy is
6701 REQUEST_CHUNKED_DECHUNK.
6702 [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815
6704 *) Support the image map format of FrontPage. For example:
6705 rect /url.hrm 10 20 30 40
6706 ["Chris O'Byrne" <obyrne@iol.ie>] PR#807
6708 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
6709 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
6711 *) AddModuleInfo directive for mod_info which allows you to annotate
6712 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
6714 *) Added NoProxy directive to avoid using ProxyRemote for selected
6715 addresses. Added ProxyDomain directive to cause unqualified
6716 names to be qualified by redirection.
6717 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
6719 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
6720 header to the remote host in the proxy. [Sameer Parekh and
6723 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
6724 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
6725 URLs, fixed rewritelog(), fixed forced response code handling on
6726 redirects from within .htaccess files, disabled pipe locking under
6727 braindead SunOS 4.1.x, allow env variables to be set even on rules with
6728 no substitution, bugfixed situations where HostnameLookups is off, made
6729 mod_rewrite more thread-safe for NT port and fixed problem when creating
6730 an empty query string via "xxx?".
6731 This update also removes the copyright of Ralf S. Engelschall,
6732 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
6733 exclusively copyrighted by the Apache Group now. This happened because
6734 the author now has gifted mod_rewrite exclusively to the Apache Group and
6735 no longer maintains an external version.
6736 [Ralf S. Engelschall]
6738 *) API: Added child_init function to module structure. This is called
6739 once per "heavy-weight process" before any requests are handled.
6740 See http_config.h for more details. [Dean Gaudet]
6742 *) Anonymous_LogEmail was logging on each subrequest.
6743 [Dean Gaudet] PR#421, 868
6745 *) API: Added is_initial_req() which tests if the request being
6746 processed is the initial request, or a subrequest.
6749 *) Extended SSI (mod_include) now handles additional relops for
6750 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
6752 *) Configure fixed to correctly propagate user-selected options and
6753 settings (such as CC and OPTIM) to Makefiles other than
6754 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
6756 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
6757 directory indices to start with the contents of the HeaderName file
6758 if there is one. If there isn't one, the behaviour is unchanged.
6759 [Ken Coar, Roy Fielding, Andrey A. Chernov]
6761 *) WIN32: Modules can now be dynamically loaded DLLs using the
6762 LoadModule/LoadFile directives. Note that module DLLs must be
6763 compiled with the multithreaded DLL version of the runtime library.
6764 [Alexei Kosut and Ben Laurie]
6766 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
6767 This allows the admin to completely remove automatic indexing
6768 from the server, while still supporting the basic functions of
6769 trailing-slash redirects and DirectoryIndex files. Note that if
6770 you're carrying over an old Configuration file and you use directory
6771 indexing then you'll want to add:
6773 Module autoindex_module mod_autoindex.o
6775 before mod_dir in your Configuration. [Dean Gaudet]
6777 *) popendir/pclosedir created to properly protect directory scanning.
6778 [Dean Gaudet] PR#525
6780 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
6781 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
6782 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
6785 *) The AccessFileName directive can now take more than one filename.
6786 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
6788 *) The new mod_mime_magic can be used to "magically" determine the type
6789 of a file if the extension is unknown. Based on the unix file(1)
6790 command. [Ian Kluft <ikluft@cisco.com>]
6792 *) We now determine and display the time spent processing a
6793 request if desired. [Jim Jagielski]
6795 *) mod_status: PID field of "dead" child slots no longer displays
6796 main httpd process's PID. [Jim Jagielski]
6798 *) Makefile.nt added - to build all the bits from the command line:
6799 nmake -f Makefile.nt
6800 Doesn't yet work properly. [Ben Laurie]
6802 *) Default text of 404 error is now "Not Found" rather than the
6803 potentially misleading "File Not Found". [Ken Coar]
6805 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
6806 for the net if we require people that actually need this data to
6807 enable it. [Linus Torvalds]
6809 *) directory_walk() is an expensive function, keep a little more state to
6810 avoid needless string counting. Add two new functions make_dirstr_parent
6811 and make_dirstr_prefix which replace all existing uses of make_dirstr.
6812 The new functions are a little less general than make_dirstr, but
6813 work more efficiently (less memory, less string counting).
6816 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
6817 to LDFLAGS) to avoid complications with lex rules in make files.
6818 [Dean Gaudet] PR#372
6820 *) run_method optimized to avoid needless scanning over NULLs in the
6821 module list. [Dean Gaudet]
6823 *) Revamp of (unix) scoreboard management code such that it avoids
6824 unnecessary traversals of the scoreboard on each hit. This is
6825 particularly important for high volume sites with a large
6826 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
6827 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
6828 httpd.h. [Dean Gaudet]
6830 *) In configurations using multiple Listen statements it was possible for
6831 busy sockets to starve other sockets of service. [Dean Gaudet]
6833 *) Added hook so standalone_main can be replaced at compile time
6834 (define STANDALONE_MAIN)
6837 *) Lowest-level read/write functions in buff.c will be replaced with
6838 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
6839 compile time. The default sfio discipline will behave as apache
6840 would without sfio compiled in.
6843 *) Enhance UserDir directive (mod_userdir) to accept a list of
6844 usernames for the 'disable' keyword, and add 'enable user...' to
6845 selectively *en*able userdirs if they're globally disabled.
6848 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
6849 will work with Netscape dbm files. (dbmmanage will probably not
6850 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
6852 *) Add a ListenBacklog directive to control the backlog parameter
6853 passed to listen(). Also change the default to 511 from 512.
6856 *) API: A new handler response DONE which informs apache that the
6857 request has been handled and it can finish off quickly, similar to
6858 how it handles errors. [Rob Hartill]
6860 *) Turn off chunked encoding after sending terminating chunk/footer
6861 so that we can't do it twice by accident. [Roy Fielding]
6863 *) mod_expire also issues Cache-Control: max-age headers.
6866 *) API: Added kill_only_once option for free_proc_chain so that it won't
6867 aggressively try to kill off specific children. For fastcgi.
6868 [Stanley Gambarin <gambarin@OpenMarket.com>]
6870 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
6872 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
6873 When used together, these cause mod_dir to emit HEIGHT and WIDTH
6874 attributes in the FancyIndexing IMG tags. [Ken Coar]
6876 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
6878 *) PORT: Added Windows NT support
6879 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
6881 Changes with Apache 1.2.6
6883 *) mod_include when using XBitHack Full would send ETags in addition to
6884 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
6885 [Dean Gaudet] PR#1133
6887 *) SECURITY: When a client connects to a particular port/addr, and
6888 gives a Host: header ensure that the virtual host requested can
6889 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
6891 *) Support virtual hosts with wildcard port and/or multiple ports
6892 properly. [Ed Korthof <ed@organic.com>]
6894 *) Fixed some case-sensitivity issues according to RFC2068.
6897 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
6898 and mod_include.c. [Dean Gaudet]
6900 *) Variable 'cwd' was being used pointlessly before being set.
6903 *) SIGURG doesn't exist on all platforms.
6904 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
6906 *) When an error occurs during a POST, or other operation with a
6907 request body, the body has to be read from the net before allowing
6908 a keepalive session to continue. [Roy Fielding] PR#1399
6910 *) When an error occurs in fcntl() locking suggest the user look up
6911 the docs for LockFile. [Dean Gaudet]
6913 *) table_set() and table_unset() did not deal correctly with
6914 multiple occurrences of the same key. [Stephen Scheck
6915 <sscheck@infonex.net>, Ben Laurie] PR#1604
6917 *) send_fd_length() did not calculate total_bytes_sent properly in error
6918 cases. [Ben Reser <breser@regnow.com>] PR#1366
6920 *) r->connection->user was allocated in the wrong pool causing corruption
6921 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
6923 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
6924 Also removed the auto-generated link to www.apache.org that was the
6925 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
6927 *) Multiple "close" tokens may have been set in the "Connection"
6928 header, not an error, but a waste.
6929 [Ronald.Tschalaer@psi.ch] PR#1683
6931 *) "basic" and "digest" auth tokens should be tested case-insensitive.
6932 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
6934 *) It appears the "257th byte" bug (see
6935 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
6936 at the 256th byte as well. Fixed. [Dean Gaudet]
6938 *) mod_rewrite would not handle %3f properly in some situations.
6941 *) Apache could generate improperly chunked HTTP/1.1 responses when
6942 the bputc() or rputc() functions were used by modules (such as
6943 mod_include). [Dean Gaudet]
6945 *) #ifdef wrap a few #defines in httpd.h to make life easier on
6946 some ports. [Ralf Engelschall]
6948 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
6950 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
6952 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
6954 Changes with Apache 1.2.5
6956 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
6957 only an issue on systems without a MAXDNAME define or where
6958 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
6960 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
6963 *) Fix core dump in the ftp proxy when reading incorrectly formatted
6964 directory listings. [Marc Slemko]
6966 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
6969 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
6970 is used to read various types of files such as htaccess and
6971 htpasswd files. [Marc Slemko]
6973 *) SECURITY: Ensure that the buffer returned by ht_time is always
6974 properly null terminated. [Marc Slemko]
6976 *) SECURITY: General mod_include cleanup, including fixing several
6977 possible buffer overflows and a possible infinite loop. This cleanup
6978 was done against 1.3 code and then backported to 1.2, the result
6979 is a large difference (due to indentation cleanup in 1.3 code).
6980 Users interested in seeing a smaller set of relevant differences
6981 should consider comparing against src/modules/standard/mod_include.c
6982 from the 1.3b3 release. Non-indentation changes to mod_include
6983 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
6985 *) SECURITY: Numerous changes to mod_imap in a general cleanup
6986 including fixing a possible buffer overflow. This cleanup also
6987 was done with 1.3 code as a basis, see the the previous note
6988 about mod_include. [Dean Gaudet]
6990 *) SECURITY: If a htaccess file can not be read due to bad
6991 permissions, deny access to the directory with a HTTP_FORBIDDEN.
6992 The previous behavior was to ignore the htaccess file if it could not
6993 be read. This change may make some setups with unreadable
6994 htaccess files stop working. PR#817 [Marc Slemko]
6996 *) SECURITY: no2slash() was O(n^2) in the length of the input.
6997 Make it O(n). This inefficiency could be used to mount a denial
6998 of service attack against the Apache server. Thanks to
6999 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting
7002 *) mod_include used uninitialized data for some uses of && and ||.
7003 [Brian Slesinsky <bslesins@wired.com>] PR#1139
7005 *) mod_imap should decline all non-GET methods.
7006 [Jay Bloodworth <jay@pathways.sde.state.sc.us>]
7008 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7010 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7011 r->filename. Since those two are meant to be in sync with each other
7012 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
7014 *) mod_include did not properly handle all possible redirects from sub-
7015 requests. [Ken Coar]
7017 *) Inetd mode (which is buggy) uses timeouts without having setup the
7018 jmpbuffer. [Dean Gaudet] PR#1064
7020 *) Work around problem under Linux where a child will start looping
7021 reporting a select error over and over.
7022 [Rick Franchuk <rickf@transpect.net>] PR#1107
7024 Changes with Apache 1.2.4
7026 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
7027 always making requests with the full-URI instead of just the URI path.
7028 [Marc Slemko, Roy Fielding]
7030 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
7031 on this platform. [Marc Slemko]
7033 Changes with Apache 1.2.3
7035 *) The request to a remote proxy was mangled if it was generated as the
7036 result of a ProxyPass directive. URL schemes other than http:// were not
7037 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
7038 PR#812 [Lars Eilebrecht]
7040 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7041 information for case where proxy module is not available. [Marc Slemko]
7043 *) Force proxy to always respond as HTTP/1.0, which it was failing to
7044 do for errors and cached responses. [Roy Fielding]
7046 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
7048 Changes with Apache 1.2.2 [not released]
7050 *) Fixed another long-standing bug in sub_req_lookup_file where it would
7051 happily skip past access checks on subdirectories looked up with relative
7052 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
7055 *) Add lockfile name to error message printed out when
7056 USE_FLOCK_SERIALIZED_ACCEPT is defined.
7059 *) Enhanced the chunking and error handling inside the buffer functions.
7060 [Dean Gaudet, Roy Fielding]
7062 *) When merging the main server's <Directory> and <Location> sections into
7063 a vhost, put the main server's first and the vhost's second. Otherwise
7064 the vhost can't override the main server. [Dean Gaudet] PR#717
7066 *) The <Directory> code would merge and re-merge the same section after
7067 a match was found, possibly causing problems with some modules.
7070 *) Fixed an infinite loop in mod_imap for references above the server root.
7071 [Dean Gaudet] PR#748
7073 *) mod_include cleanup showed that handle_else was being used to handle
7074 endif. It didn't cause problems, but it was cleaned up too.
7077 *) Last official synchronization of mod_rewrite with author version (because
7078 mod_rewrite is now directly developed by the author at the Apache Group):
7079 o added diff between mod_rewrite 3.0.6+ and 3.0.9
7080 minus WIN32/NT stuff, but plus copyright removement.
7082 - workaround for detecting infinite rewriting loops
7083 - fixed setting of env vars when "-" is used as subst string
7084 - fixed forced response code on redirects (PR#777)
7085 - fixed cases where r->args is ""
7086 - kludge to disable locking on pipes under braindead SunOS
7087 - fix for rewritelog in cases where remote hostname is unknown
7088 - fixed totally damaged request_rec walk-back loop
7089 o remove static from local data and add static to global ones.
7090 o replaced ugly proxy finding stuff by simple
7091 find_linked_module("mod_proxy") call.
7092 o added missing negation char on rewritelog()
7093 o fixed a few comment typos
7094 [Ralf S. Engelschall]
7096 *) Anonymous_LogEmail was logging on each subrequest.
7097 [Dean Gaudet] PR#421, PR#868
7099 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7100 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7101 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
7102 Additionally mod_browser now triggers during translate_name to workaround
7103 a deficiency in the header_parse phase.
7104 [Dean Gaudet] PR#875
7106 *) get_client_block() returns wrong length if policy is
7107 REQUEST_CHUNKED_DECHUNK.
7108 [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815
7110 *) Properly treat <files> container like other containers in mod_info.
7111 [Marc Slemko] PR#848
7113 *) The proxy didn't treat the "Host:" keyword of the host header as case-
7114 insensitive. The proxy would corrupt the first line of a response from
7115 an HTTP/0.9 server. [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#813,814
7117 *) mod_include would log some bogus values occasionally.
7118 [Skip Montanaro <skip@calendar.com>, Marc Slemko] PR#797
7120 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
7121 under Solaris 2.x (up through 2.5.1). It has been fixed.
7122 [Dean Gaudet] PR#832
7124 *) API: In HTTP/1.1, whether or not a request message contains a body
7125 is independent of the request method and based solely on the presence
7126 of a Content-Length or Transfer-Encoding. Therefore, our default
7127 handlers need to be prepared to read a body even if they don't know
7128 what to do with it; otherwise, the body would be mistaken for the
7129 next request on a persistent connection. discard_request_body()
7130 has been added to take care of that. [Roy Fielding] PR#378
7132 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
7133 release version number, such that it always increases along the
7134 same lines as our source code branching. [Roy Fielding]
7136 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
7138 Changes with Apache 1.2.1
7140 *) SECURITY: Don't serve file system objects unless they are plain files,
7141 symlinks, or directories. This prevents local users from using pipes
7142 or named sockets to invoke programs for an extremely crude form of
7145 *) SECURITY: HeaderName and ReadmeName were settable in .htaccess and
7146 could contain "../" allowing a local user to "publish" any file on
7147 the system. No slashes are allowed now. [Dean Gaudet]
7149 *) SECURITY: It was possible to violate the symlink Options using mod_dir
7150 (headers, readmes, titles), mod_negotiation (type maps), or
7151 mod_cern_meta (meta files). [Dean Gaudet]
7153 *) SECURITY: Apache will refuse to run as "User root" unless
7154 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
7156 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
7157 if it contained a .htaccess disallowing symlinks. This is contrary
7158 to the rule that symlink permissions are tested with the symlink
7159 options of the parent directory. [Dean Gaudet] PR#353
7161 *) CONFIG: The LockFile directive can be used to place the serializing
7162 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
7163 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
7166 *) Request processing now retains state of whether or not the request
7167 body has been read, so that internal redirects and subrequests will
7168 not try to read it twice (and block). [Roy Fielding]
7170 *) Add a placeholder in modules/Makefile to avoid errors with certain
7171 makes. [Marc Slemko]
7173 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.
7174 [Dean Gaudet] PR#644
7176 *) mod_include was not properly changing the current directory.
7177 [Marc Slemko] PR#742
7179 *) Attempt to work around problems with third party libraries that do not
7180 handle high numbered descriptors (examples include bind, and
7181 solaris libc). On all systems apache attempts to keep all permanent
7182 descriptors above 15 (called the low slack line). Solaris users
7183 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
7184 which keeps all non-FILE * descriptors above 255. On all systems
7185 this should make supporting large numbers of vhosts with many open
7186 log files more feasible. If this causes trouble please report it,
7187 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
7188 [Dean Gaudet] various PRs
7190 *) Related to the last entry, network sockets are now opened before
7191 log files are opened. The only known case where this can cause
7192 problems is under Solaris with many virtualhosts and many Listen
7193 directives. But using -DHIGH_SLACK_LINE=256 described above will
7194 work around this problem. [Dean Gaudet]
7196 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
7199 *) Improved unix error response logging. [Marc Slemko]
7201 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
7202 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
7203 when a URL http://... was used in conjunction with a special
7204 redirect flag, e.g. R=permanent, the permanent status was lost.
7205 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>, Ralf S. Engelschall]
7207 *) If an object has multiple variants that are otherwise equal Apache
7208 would prefer the last listed variant rather than the first.
7211 *) "make clean" at the top level now removes *.o. [Dean Gaudet] PR#752
7213 *) mod_status dumps core in inetd mode. [Marc Slemko and Roy Fielding]
7216 *) pregsub had an off-by-1 in its error checking code. [Alexei Kosut]
7218 *) PORT: fix rlim_t problems with AIX 4.2. [Marc Slemko] PR#333
7220 *) PORT: Update UnixWare support for 2.1.2.
7221 [Lawrence Rosenman <ler@lerctr.org>] PR#511
7223 *) PORT: NonStop-UX [Joachim Schmitz <schmitz_joachim@tandem.com>] PR#327
7225 *) PORT: Update ConvexOS support for 11.5.
7226 [David DeSimone <fox@convex.com>] PR#399
7228 *) PORT: Support for DEC cc compiler under ULTRIX.
7229 ["P. Alejandro Lopez-Valencia" <alejolo@ideam.gov.co>] PR#388
7231 *) PORT: Support for Maxion/OS SVR4.2 Real Time Unix. [no name given] PR#383
7233 *) PORT: Workaround for AIX 3.x compiler bug in http_bprintf.c.
7234 [Marc Slemko] PR#725
7236 *) PORT: fix problem compiling http_bprintf.c with gcc under SCO
7237 [Marc Slemko] PR#695
7239 Changes with Apache 1.2
7241 Changes with Apache 1.2b11
7243 *) Fixed open timestamp fd in proxy_cache.c [Chuck Murcko]
7245 *) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
7246 [Doug MacEachern, Rob Hartill]
7248 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
7249 reading from one buffer and writing to another, at least until it has
7250 a custom timeout handler. [Roy Fielding and Petr Lampa]
7252 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
7253 apparently due to a mismatch between sigaction and setjmp.
7254 [Roy Fielding] PR#502
7256 *) Log correct status code if we timeout before receiving a request (408)
7257 or if we received a request-line that was too long to process (414).
7258 [Ed Korthof and Roy Fielding] PR#601
7260 *) Virtual hosts with the same ServerName, but on different ports, were
7261 not being selected properly. [Ed Korthof]
7263 *) Added code to return the requested IP address from proxy_host2addr()
7264 if gethostbyaddr() fails due to reverse DNS lookup problems. Original
7265 change submitted by Jozsef Hollosi <hollosi@sbcm.com>.
7266 [Chuck Murcko] PR#614
7268 *) If multiple requests on a single connection are used to retrieve
7269 data from different virtual hosts, the virtual host list would be
7270 scanned starting with the most recently used VH instead of the first,
7271 causing most virtual hosts to be ignored.
7272 [Paul Sutton and Martin Mares] PR#610
7274 *) The OS/2 handling of process group was broken by a porting patch for
7275 MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]
7277 *) Inherit virtual server port from main server if none (or "*") is
7278 given for VirtualHost. [Dean Gaudet] PR#576
7280 *) If the lookup for a DirectoryIndex name with content negotiation
7281 has found matching variants, but none are acceptable, return the
7282 negotiation result if there are no more DirectoryIndex names to lookup.
7283 [Petr Lampa and Roy Fielding]
7285 *) If a soft_timeout occurs after keepalive is set, then the main child
7286 loop would try to read another request even though the connection
7287 has been aborted. [Roy Fielding]
7289 *) Configure changes: Allow for whitespace at the start of a
7290 Module declaration. Also, be more understanding about the
7291 CC=/OPTIM= format in Configuration. Finally, fix compiler
7292 flags if using HP-UX's cc compiler. [Jim Jagielski]
7294 *) Subrequests and internal redirects now inherit the_request from the
7295 original request-line. [Roy Fielding]
7297 *) Test for error conditions before creating output header fields, since
7298 we don't want the error message to include those fields. Likewise,
7299 reset the content_language(s) and content_encoding of the response
7300 before generating or redirecting to an error message, since the new
7301 message will have its own Content-* definitions. [Dean Gaudet]
7303 *) Restored the semantics of headers_out (headers sent only with 200..299
7304 and 304 responses) and err_headers_out (headers sent with all responses).
7305 Avoid the overhead of copying tables if err_headers_out is empty
7306 (the usual case). [Roy Fielding]
7308 *) Fixed a couple places where a check for the default Content-Type was
7309 not properly checking both the value configured by the DefaultType
7310 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
7311 of DEFAULT_TYPE to match the documented default (text/plain).
7312 [Dean Gaudet] PR#506
7314 *) Escape the HTML-sensitive characters in the Request-URI that is
7315 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
7317 *) Properly initialize the flock structures used by the mutex locking
7318 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
7321 *) The method for determining PATH_INFO has been restored to the pre-1.2b
7322 (and NCSA httpd) definition wherein it was the extra path info beyond
7323 the CGI script filename. The environment variable FILEPATH_INFO has
7324 been removed, and instead we supply the original REQUEST_URI to any
7325 script that wants to be Apache-specific and needs the real URI path.
7326 This solves a problem with existing scripts that use extra path info
7327 in the ScriptAlias directive to pass options to the CGI script.
7330 *) The _default_ change in 1.2b10 will change the behaviour on configs
7331 that use multiple Listen statements for listening on multiple ports.
7332 But that change is necessary to make _default_ consistent with other
7333 forms of <VirtualHost>. It requires such configs to be modified
7334 to use <VirtualHost _default_:*>. The documentation has been
7335 updated. [Dean Gaudet] PR#530
7337 *) If an ErrorDocument CGI script is used to respond to an error
7338 generated by another CGI script which has already read the message
7339 body of the request, the server would block trying to read the
7340 message body again. [Rob Hartill]
7342 *) signal() replacement conflicted with a define on QNX (and potentially
7343 other platforms). Fixed. [Ben Laurie] PR#512
7345 Changes with Apache 1.2b10
7347 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
7348 to be configured via -D in Configuration. [Dean Gaudet] PR#449
7350 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
7352 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]
7354 *) In mod_proxy.c, check return values for proxy_host2addr() when reading
7355 config, in case the hostent struct returned is trash.
7356 [Chuck Murcko] PR #491
7358 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
7359 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
7361 Changes with Apache 1.2b9 [never announced]
7363 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
7364 changes and in anticipation of 1.2 final release. [Roy Fielding]
7366 *) Fix problem with scripts not receiving a SIGPIPE when client drops
7367 the connection (e.g., when user presses Stop). Apache will now stop
7368 trying to send a message body immediately after an error from write.
7369 [Roy Fielding and Nathan Kurz] PR#335
7371 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
7372 than mod_alias, and mod_alias has higher priority than mod_proxy;
7373 rearranged other modules to enhance understanding of their purpose
7374 and relative order (and maybe even reduce some overhead).
7375 [Roy Fielding and Sameer Parekh]
7377 *) Fix graceful restart. Eliminate many signal-related race
7378 conditions in both forms of restart, and in SIGTERM. See
7379 htdocs/manual/stopping.html for details on stopping and
7380 restarting the parent. [Dean Gaudet]
7382 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
7383 memory allocator to avoid a behaviour that required extra blocks to
7384 be allocated. [Dean Gaudet]
7386 *) Allow suexec to access files relative to current directory but not
7387 above. (Excluding leading / or any .. directory.) [Ken Coar]
7390 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
7391 PR#367, 368, 354, 453
7393 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
7394 while obtaining the /~user and save the username in a separate data
7395 area so that it won't be overwritten by the call to getgrgid(), and
7396 fix some misuse of the pool string allocation functions. Also fixes
7397 a general problem with parsing URL query info into args for CGI scripts.
7398 [Roy Fielding] PR#339, 367, 354, 453
7400 *) Fix IRIX warning about bzero undefined. [Marc Slemko]
7402 *) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
7404 *) Corrected spelling of "authoritative". AuthDBAuthoratative became
7405 AuthDBAuthoritative. [Marc Slemko] PR#420
7407 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
7409 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
7410 object that can't be PUT, or FOOBAR for some method FOOBAR that
7411 apache doesn't know about at all). Log 404s that occur in mod_include.
7412 [Paul Sutton, John Van Essen]
7414 *) If a soft timeout (or lingerout) occurs while trying to flush a
7415 buffer or write inside buff.c or fread'ing from a CGI's output,
7416 then the timeout would be ignored. [Roy Fielding] PR#373
7418 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
7419 parsing of headers. If the terminating empty-line CRLF occurs starting
7420 at the 256th or 257th byte of output, then Navigator will think a normal
7421 image is invalid. We are guessing that this is because their initial
7422 read of a new request uses a 256 byte buffer. We check the bytes written
7423 so far and, if we are about to tickle the bug, we instead insert a
7424 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
7426 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
7427 of an external redirection. [Roy Fielding and Paul Sutton]
7429 *) Configure would create a broken Makefile if the configuration file
7430 contained a commented-out Rule. [Roy Fielding]
7432 *) Promote per_dir_config and subprocess_env from the subrequest to the
7433 main request in mod_negotiation. In particular this fixes a bug
7434 where <Files> sections wouldn't properly apply to negotiated content.
7437 *) Fix a potential deadlock in mod_cgi script_err handling.
7438 [Ralf S. Engelschall]
7440 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
7443 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
7444 .htaccess files because the RewriteBase was not replaced correctly.
7445 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
7446 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
7448 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
7449 1.x the settings are those of pre-1.2b8. For 2.x we include
7450 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
7451 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
7452 [Dean Gaudet] PR#336, PR#340
7454 *) Redirect did not preserve ?query_strings when present in the client's
7455 request. [Dean Gaudet]
7457 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
7459 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
7461 *) Add UnixWare compile/install instructions. [Chuck Murcko]
7463 *) Add mod_example (illustration of API techniques). [Ken Coar]
7465 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
7467 *) Improve handling of directories when filenames have spaces in them.
7470 *) For hosts with multiple IP addresses, try all additional addresses if
7471 necessary to get a connect. Fail only if hostent address list is
7472 exhausted. [Chuck Murcko]
7474 *) More signed/unsigned port fixes. [Dean Gaudet]
7476 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
7479 Changes with Apache 1.2b8
7481 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
7482 to it. [Marc Slemko]
7484 *) The addition of <Location> and <File> directives made the
7485 sub_req_lookup_simple() function bogus, so we now handle
7486 the special cases directly. [Dean Gaudet]
7488 *) We now try to log where the server is dumping core when a fatal
7489 signal is received. [Ken Coar]
7491 *) Improved lingering_close by adding a special timeout, removing the
7492 spurious log messages, removing the nonblocking settings (they
7493 are not needed with the better timeout), and adding commentary
7494 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
7495 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
7497 *) Send error messages about setsockopt failures to the server error
7498 log instead of stderr. [Roy Fielding]
7500 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
7502 *) Stopgap solution for CGI 3-second delay with server-side includes: if
7503 processing a subrequest, allocate memory from r->main->pool instead
7504 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
7505 in the middle of an SSI request. [Dean Gaudet] PR #122
7507 *) Fixed status of response when POST is received for a nonexistent URL
7508 (was sending 405, now 404) and when any method is sent with a
7509 full-URI that doesn't match the server and the server is not acting
7510 as a proxy (was sending 501, now 403). [Roy Fielding]
7512 *) Host port changed to unsigned short. [Ken Coar] PR #276
7514 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
7516 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
7518 *) Report extra info from errno with many errors that cause httpd to exit.
7519 spawn_child, popenf, and pclosef now have valid errno returns in the
7520 event of an error. Correct problems where errno was stomped on
7521 before being reported. [Dean Gaudet]
7523 *) In the proxy, if the cache filesystem was full, garbage_coll() was
7524 never called, and thus the filesystem would remain full indefinitely.
7525 We now also remove incomplete cache files left if the origin server
7526 didn't send a Content-Length header and either the client has aborted
7527 transfer or bwrite() to client has failed. [Petr Lampa]
7529 *) Fixed the handling of module and script-added header fields.
7530 Improved the interface for sending header fields and reduced
7531 the duplication of code between sending okay responses and errors.
7532 We now always send both headers_out and err_headers_out, and
7533 ensure that the server-reserved fields are not being overridden,
7534 while not overriding those that are not reserved. [Roy Fielding]
7536 *) Moved transparent content negotiation fields to err_headers_out
7537 to reflect above changes. [Petr Lampa]
7539 *) Fixed the determination of whether or not we should make the
7540 connection persistent for all of the cases where some other part
7541 of the server has already indicated that we should not. Also
7542 improved the ordering of the test so that chunked encoding will
7543 be set whenever it is desired instead of only when KeepAlive
7544 is enabled. Added persistent connection capability for most error
7545 responses (those that do not indicate a bad input stream) when
7546 accessed by an HTTP/1.1 client. [Roy Fielding]
7548 *) Added missing timeouts for sending header fields, error responses,
7549 and the last chunk of chunked encoding, each of which could have
7550 resulted in a process being stuck in write forever. Using soft_timeout
7551 requires that the sender check for an aborted connection rather than
7552 continuing after an EINTR. Timeouts that used to be initiated before
7553 send_http_header (and never killed) are now initiated only within or
7554 around the routines that actually do the sending, and not allowed to
7555 propagate above the caller. [Roy Fielding]
7557 *) mod_auth_anon required an @ or a . in the email address, not both.
7560 *) per_dir_defaults weren't set correctly until directory_walk for
7561 name-based vhosts. This fixes an obscure bug with the wrong config
7562 info being used for vhosts that share the same ip as the server.
7565 *) Improved generation of modules/Makefile to be more generic for
7566 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
7568 *) Generate makefile dependency for Configuration based on the actual
7569 name given when running the Configure process. [Dean Gaudet]
7571 *) Fixed problem with vhost error log not being set prior to
7572 initializing virtual hosts. [Dean Gaudet]
7574 *) Fixed infinite loop when a trailing slash is included after a type map
7575 file URL (extra path info). [Petr Lampa]
7577 *) Fixed server status updating of per-connection counters. [Roy Fielding]
7579 *) Add documentation for DNS issues (reliability and security), and try
7580 to explain the virtual host matching process. [Dean Gaudet]
7582 *) Try to continue gracefully by disabling the vhost if a DNS lookup
7583 fails while parsing the configuration file. [Dean Gaudet]
7585 *) Improved calls to setsockopt. [Roy Fielding]
7587 *) Negotiation changes: Don't output empty content-type in variant list;
7588 Output charset in variant list; Return sooner from handle_multi() if
7589 no variants found; Add handling of '*' wildcard in Accept-Charset.
7590 [Petr Lampa and Paul Sutton]
7592 *) Fixed overlaying of request/sub-request notes and headers in
7593 mod_negotiation. [Dean Gaudet]
7595 *) If two variants' charset quality are equal and one is the default
7596 charset (iso-8859-1), then prefer the variant that was specifically
7597 listed in Accept-Charset instead of the default. [Petr Lampa]
7599 *) Memory allocation problem in push_array() -- it would corrupt memory
7600 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
7602 *) invoke_handler() doesn't handle mime arguments in content-type
7605 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
7608 *) Fixed problem with ErrorDocument not working for virtual hosts
7609 due to one of the performance changes in 1.2b7. [Dean Gaudet]
7611 *) Log an error message if we get a request header that is too long,
7612 since it may indicate a buffer overflow attack. [Marc Slemko]
7614 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
7615 not reject URLs without a double-slash, as per RFC2068 section 3.2.
7616 [Ken Coar] PR #146, #187
7618 *) Added table entry placeholder for new header_parser callback
7619 in all of the distributed modules. [Ken Coar] PR #191
7621 *) Allow for cgi files without the .EXE extension on them under OS/2.
7622 [Garey Smiley] PR #59
7624 *) Fixed error message when resource is not found and URL contains
7625 path info. [Petr Lampa and Dean Gaudet] PR #40
7627 *) Fixed user and server confusion over what should be a virtual host
7628 and what is the main server, resulting in access to something
7629 other than the name defined in the virtualhost directive (but
7630 with the same IP address) failing. [Dean Gaudet]
7632 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
7633 AIX; improves the redirection stuff to enable the users to generally
7634 redirect to http, https, gopher and ftp; added TIME variable for
7635 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
7636 special patterns >STRING, <STRING and =STRING to RewriteCond, which
7637 can be used in conjunction with %{TIME} or other variables to create
7638 time-dependent rewriting rules. [Ralf S. Engelschall]
7640 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
7641 Module authors may need to adjust their code for proper cleanup to take
7642 place (that is, call note_cleanups_for_fd()). This change fixes problems
7643 with file descriptors being erroneously closed when the proxy module was
7644 in use. [Ben Laurie]
7646 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
7647 initgroups() to hose the group information needed for later
7648 comparisons. [Randy Terbush]
7650 *) Remove unnecessary call to va_end() in create_argv() which
7651 caused a SEGV on some systems.
7653 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
7656 *) Clear memory allocated for listeners. [Randy Terbush]
7658 *) Improved handling of IP address as a virtualhost address and
7659 introduced "_default_" as a synonym for the default vhost config.
7660 [Dean Gaudet] PR #212
7662 Changes with Apache 1.2b7
7664 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
7666 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
7668 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
7669 - replace protocol response numbers with symbols
7670 - save variant-list into main request notes
7671 - free allocated memory from subrequests
7672 - merge notes, headers_out and err_headers_out
7674 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
7675 "HTTP/#.# ###*" to be more lenient about what we accept.
7678 *) more proxy FTP bug fixes:
7679 - Changed send_dir() to remove user/passwd from displayed URL.
7680 - Changed login error messages to be more descriptive.
7681 - remove setting of SO_DEBUG socket option
7682 - Make ftp_getrc() more lenient about multiline responses,
7683 specifically, 230 responses which don't have continuation 230-
7684 on each line). These seem to be all NT FTP servers, and while
7685 perhaps questionable, they appear to be legal by RFC 959.
7686 - Add missing kill_timeout() after transfer to user completes.
7689 *) Fixed problem where a busy server could hang when restarting
7690 after being sent a SIGHUP due to child processes not exiting.
7693 *) Modify mod_include escaping so a '\' only signifies an escaped
7694 character if the next character is one that needs
7695 escaping. [Ben Laurie]
7697 *) Eliminated possible infinite loop in mod_imap when relative URLs are
7698 used with a 'base' directive that does not have a '/' in it.
7699 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
7701 *) Reduced the default timeout from 1200 seconds to 300, and the
7702 one in the sample configfile from 400 to 300. [Marc Slemko]
7704 *) Stop vbprintf from crashing if given a NULL string pointer;
7705 print (null) instead. [Ken Coar]
7707 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
7708 [Marc Slemko and Roy Fielding]
7710 *) Fixed problem with mod_cgi-generated internal redirects trying to
7711 read the request message-body twice. [Archie Cobbs and Roy Fielding]
7713 *) Reduced timeout on lingering close, removed possibility of a blocked
7714 read causing the child to hang, and stopped logging of errors if
7715 the socket is not connected (reset by client). [Roy Fielding]
7717 *) Rearranged main child loop to remove duplication of code in
7718 select/accept and keep-alive requests, fixed several bugs regarding
7719 checking scoreboard_image for exit indication and failure to
7720 account for all success conditions and trap all error conditions,
7721 prevented multiple flushes before closing the socket; close the entire
7722 socket buffer instead of just one descriptor, prevent logging of
7723 EPROTO and ECONNABORTED on platforms where supported, and generally
7724 improved readability. [Roy Fielding]
7726 *) Extensive performance improvements. Cleaned up inefficient use of
7727 auto initializers, multiple is_matchexp calls on a static string,
7728 and excessive merging of response_code_strings. [Dean Gaudet]
7730 *) Added double-buffering to mod_include to improve performance on
7731 server-side includes. [Marc Slemko]
7733 *) Several fixes for suexec wrapper. [Randy Terbush]
7734 - Make wrapper work for files on NFS filesystem.
7735 - Fix portability problem of MAXPATHLEN.
7736 - Fix array overrun problem in clean_env().
7737 - Fix allocation of PATH environment variable
7739 *) Removed extraneous blank line is description of mod_status chars.
7742 *) Logging of errors from the call_exec routine simply went nowhere,
7743 since the logfile fd has been closed, so now we send them to stderr.
7744 [Harald T. Alvestrand]
7746 *) Fixed core dump when DocumentRoot is a CGI.
7747 [Ben Laurie, reported by geddis@tesserae.com]
7749 *) Fixed potential file descriptor leak in mod_asis; updated it and
7750 http_core to use pfopen/pfclose instead of fopen/fclose.
7751 [Randy Terbush and Roy Fielding]
7753 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
7754 as the DEC Alpha which is 64-bit but uses 32-bit ints.
7755 [Dean Gaudet and Ken Coar]
7757 *) Return a 302 response code to the client when sending a redirect
7758 due to a missing trailing '/' on a directory instead of a 301; now
7759 it is cacheable. [Markus Gyger]
7761 *) Fix condition where, if a bad directive occurs in .htaccess, and
7762 sub_request() goes first to this directory, then log_reason() will
7763 SIGSEGV because it doesn't have initialized r->per_dir_config.
7764 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
7766 *) Fix handling of lang_index in is_variant_better(). This was
7767 causing problems which resulted in the server sending the
7768 wrong language document in some cases. [Petr Lampa]
7770 *) Remove free() from clean_env() in suexec wrapper. This was nuking
7771 the clean environment on some systems.
7773 *) Tweak byteserving code (e.g. serving PDF files) to work around
7774 bugs in Netscape Navigator and Microsoft Internet Explorer.
7775 Emit Content-Length header when sending multipart/byteranges.
7778 *) Port to HI-UX/WE2. [Nick Maclaren]
7780 *) Port to HP MPE operating system for HP 3000 machines
7781 [Mark Bixby <markb@cccd.edu>]
7783 *) Fixed bug which caused a segmentation fault if only one argument
7784 given to RLimit* directives. [Ed Korthof]
7786 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
7788 *) Improved buffered output to the client by delaying the flush decision
7789 until the BUFF code is actually about to read the next request.
7790 This fixes a problem introduced in 1.2b5 with clients that send
7791 an extra CRLF after a POST request. Also improved chunked output
7792 performance by combining writes using writev() and removing as
7793 many bflush() calls as possible. NOTE: Platforms without writev()
7794 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
7795 or Configure, unless we have already done so. [Dean Gaudet]
7797 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
7799 *) Fixed mod_info output corruption bug introduced by buffer overflow
7800 fixes. [Dean Gaudet]
7802 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
7803 for the special case of a 304 response. [Paul Sutton]
7805 *) Improved handling of TRACE method by bypassing normal method handling
7806 and header parsing routines; fixed Allow response to always allow TRACE.
7809 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
7811 *) Cleaned-up some of the generated HTML. [Ken Coar]
7813 Changes with Apache 1.2b6
7815 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
7817 *) Fix typo introduced in fix for potential infinite loop around
7818 accept() in child_main(). This change caused the rev to 1.2b6.
7819 1.2b5 was never a public beta.
7821 Changes with Apache 1.2b5
7823 *) Change KeepAlive semantics (On|Off instead of a number), add
7824 MaxKeepAliveRequests directive. [Alexei Kosut]
7826 *) Various NeXT compilation patches, as well as a change in
7827 regex/regcomp.c since that file also used a NEXT define.
7830 *) Allow * to terminate the end of a directory match in mod_dir.
7831 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
7833 *) Don't call can_exec() if suexec_enabled. Calling this requires
7834 scripts executed by the suexec wrapper to be world executable, which
7835 defeats one of the advantages of running the wrapper. [Randy Terbush]
7837 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
7840 *) Migration from sprintf() to snprintf() to avoid buffer
7841 overflows. [Marc Slemko]
7843 *) Provide portable snprintf() implementation (ap_snprintf)
7844 as well as *cvt family. [Jim Jagielski]
7846 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
7849 *) Remove mod_fastcgi.c from the distribution. This module appears
7850 to be maintained more through the Open Market channels and should
7851 continue to be easily available at http://www.fastcgi.com/
7853 *) Fixed bug in modules/Makefile that wouldn't allow building in more
7854 than one subdirectory (or cleaning, either). [Jeremy Laidman]
7856 *) mod_info assumed that the config files were relative to ServerRoot.
7859 *) CGI scripts called as an error document resulting from failed
7860 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
7862 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
7865 *) Properly check errno to prevent display of a directory index
7866 when server receives a long enough URL to confuse stat().
7869 *) Several security enhancements to suexec wrapper. It is _highly_
7870 recommended that previously installed versions of the wrapper
7871 be replaced with this version. [Randy Terbush, Jason Dour]
7873 - ~user execution now properly restricted to ~user's home
7874 directory and below.
7875 - execution restricted to UID/GID > 100
7876 - restrict passed environment to known variables
7877 - call setgid() before initgroups() (portability fix)
7878 - remove use of setenv() (portability fix)
7880 *) Add HTTP/1.0 response forcing. [Ben Laurie]
7882 *) Add access control via environment variables. [Ben Laurie]
7884 *) Add rflush() function. [Alexei Kosut]
7886 *) remove duplicate pcalloc() call in new_connection().
7888 *) Fix incorrect comparison which could allow number of children =
7889 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
7890 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
7892 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
7893 AIX PS/2, CONVEXOS. [Jim Jagielski]
7895 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
7896 It's more portable. [Martin Kraemer]
7898 *) Replace references to make in Makefile.tmpl with $(MAKE).
7901 *) Add ProxyBlock directive w/IP address caching. Add IP address
7902 caching to NoCache directive as well. ProxyBlock works with all
7903 handlers; NoCache now also works with FTP for anonymous logins.
7904 Still more code cleanup. [Chuck Murcko]
7906 *) Add "header parse" API hook [Ben Laurie]
7908 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
7910 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
7912 *) Correctly allow access and auth directives in <Files> sections in
7913 server config files. [Alexei Kosut]
7915 *) Fix bug with ServerPath that could cause certain files to be not
7916 found by the server. [Alexei Kosut]
7918 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
7919 double-quote from text and so that it properly checks for unsupported
7920 status codes using the new index_of_response interface. [Roy Fielding]
7922 *) Multiple fixes to the lingering_close code in order to avoid being
7923 interrupted by a stray timeout, to avoid lingering on a connection
7924 that has already been aborted or never really existed, to ensure that
7925 we stop lingering as soon as any error condition is received, and to
7926 prevent being stuck indefinitely if the read blocks. Also improves
7927 reporting of error conditions. [Marc Slemko and Roy Fielding]
7929 *) Fixed initialization of parameter structure for sigaction.
7930 [mgyger@itr.ch, Adrian Filipi-Martin]
7932 *) Fixed reinitializing the parameters before each call to accept and
7933 select, and removed potential for infinite loop in accept.
7934 [Roy Fielding, after useful PR from adrian@virginia.edu]
7936 *) Fixed condition where, if a child fails to fork, the scoreboard would
7937 continue to say SERVER_STARTING forever. Eventually, the main process
7938 would refuse to start new children because count_idle_servers() will
7939 count those SERVER_STARTING entries and will always report that there
7940 are enough idle servers. [Phillip Vandry]
7942 *) Fixed bug in bcwrite regarding failure to account for partial writes.
7943 Avoided calling bflush() when the client is pipelining requests.
7944 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
7946 *) Added description of "." mode in server-status [Jim Jagielski]
7948 Changes with Apache 1.2b4
7950 *) Fix possible race condition in accept_mutex_init() that
7951 could leave a small security hole open allowing files to be
7952 overwritten in cases where the server UID has write permissions.
7955 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
7957 *) Fix portablity problem in util_script where ARG_MAX may not be
7958 defined for some systems.
7960 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
7963 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
7964 style magic #! token for better script portability. [Garey Smiley]
7966 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
7967 execution for ~userdir CGI. [Jason Dour]
7969 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
7971 *) Fix month off by one in suexec wrapper logging.
7973 Changes with Apache 1.2b3:
7975 *) Fix error in mod_cgi which could cause resources not to be properly
7976 freed, or worse. [Dean Gaudet]
7978 *) Fix find_string() NULL pointer dereference. [Howard Fear]
7980 *) Add set_flag_slot() at the request of Dirk and others.
7983 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
7985 *) Add changes to improve the error message given for invalid
7986 ServerName parameters. [Dirk vanGulik]
7988 *) Add "Authoritative" directive for Auth modules that don't
7989 currently have it. This gives admin control to assign authoritative
7990 control to an authentication scheme and allow "fall through" for
7991 those authentication modules that aren't "Authoritative" thereby
7992 allowing multiple authentication mechanisms to be chained.
7995 *) Remove requirement for ResourceConfig/AccessConfig if not using
7996 the three config file layout. [Randy Terbush]
7998 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
8000 *) Changes to suexec wrapper to fix the following problems:
8001 1. symlinked homedirs will kill ~userdirs.
8002 2. initgroups() on Linux 2.0.x clobbers gr->grid.
8003 3. CGI command lines paramters problems
8004 4. pw-pwdir for "docroot check" still the httpd user's pw record.
8005 [Randy Terbush, Jason Dour]
8007 *) Change create_argv() to accept variable arguments. This fixes
8008 a problem where arguments were not getting passed to the CGI via
8009 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
8011 *) Collapse multiple slashes in path URLs to properly apply
8012 handlers defined by <Location>. [Alexei Kosut]
8014 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
8016 *) Improve the accuracy of request duration timings by setting
8017 r->request_time in read_request_line() instead of read_request().
8020 *) Reset timeout while reading via get_client_block() in mod_cgi.c
8021 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
8023 *) Add the ability to pass different Makefile.tmpl files to Configure
8024 using the -make flag. [Rob Hartill]
8026 *) Fix coredump triggered when sending a SIGHUP to the server caused
8027 by an assertion failure, in turn caused by an uninitialised field in a
8031 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
8032 PATH_INFO from previous versions of Apache (in certain situations,
8033 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
8034 [later removed in 1.2b11]
8036 *) Add rwrite() function to API to allow for sending strings of
8037 arbitrary length. [Doug MacEachern]
8039 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
8041 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
8042 NeXT. [Jim Jagielski]
8044 *) Removed recent modification to promote the status code on internal
8045 redirects, since the correct fix was to change the default log format
8046 in mod_log_config so that it outputs the original status. [Rob Hartill]
8048 Changes with Apache 1.2b2:
8050 *) Update set_signals() to use sigaction() for setting handlers.
8051 This appears to fix a re-entrant problem in the seg_fault()
8052 bus_error() handlers. [Randy Terbush]
8054 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
8056 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
8058 *) proxy_http.c bugfixes: [Chuck Murcko]
8059 1) fixes possible NULL pointer reference w/NoCache
8060 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
8061 host would cache nothing if it was in the local domain,
8062 and the local domain was in the NoCache list)
8063 3) Adds Host: header when not available
8064 4) Some code cleanup and clarification
8066 *) mod_include.c bugfixes:
8067 1) Fixed an ommission that caused include variables to not
8068 be parsed in config errmsg directives [Howard Fear]
8069 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
8070 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
8071 4) Allow backslash-escaping to all quoted text
8072 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
8073 5) Pass variable to command line if not set in XSSI's env
8076 *) Fix infinite loop when processing Content-language lines in
8077 type-map files. [Alexei Kosut]
8079 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
8081 *) Fixed problem in set_[user|group] that prevented CGI execution
8082 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
8084 *) Added PORTING information file. [Jim Jagielski]
8086 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
8088 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
8090 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
8091 USE_FCNTL_SERIALIZED_ACCEPT was intended.
8093 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
8094 which caused problems of systems where socket s_addr is >32bits.
8096 *) Added comment to explain (r->chunked = 1) side-effect in
8097 http_protocol.c [Roy Fielding]
8099 *) Replaced use of index() in mod_expires.c with more appropriate
8100 and portable isdigit() test. [Ben Laurie]
8102 *) Updated Configure for ...
8103 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
8104 *-dg-dgux* (bad pattern match)
8105 QNX (DEF_WANTHSREGEX=yes)
8106 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
8109 and added some user diagnostic info. [Ben Laurie]
8111 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
8112 for better portability. [Jim Jagielski]
8114 *) Updated helpers/GuessOS for ...
8115 SCO 5 (recognize minor releases)
8116 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
8117 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
8118 IRIX64 (-sgi-irix64)
8119 ULTRIX (-unknown-ultrix)
8120 SINIX (-whatever-sysv4)
8121 NCR Unix (-ncr-sysv4)
8122 and fixed something in helpers/PrintPath [Ben Laurie]
8124 Changes with Apache 1.2b1
8126 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
8128 Changes with Apache 1.1.1
8130 *) Fixed bug where Cookie module would make two entries in the
8131 logfile for each access [Mark Cox]
8133 *) Fixed bug where Redirect in .htaccess files would cause memory
8134 leak. [Nathan Neulinger]
8136 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
8138 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
8140 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
8142 Changes with Apache 1.1.0
8144 *) Bring NeXT support up to date. [Takaaki Matsumoto]
8146 *) Bring QNX support up to date. [Ben Laurie]
8148 *) Make virtual hosts default to main server keepalive parameters.
8149 [Alexei Kosut, Ben Laurie]
8151 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
8153 *) Fix missing address family for connect, also remove unreachable statement
8154 in mod_proxy. [Ben Laurie]
8156 *) mod_env now turned on by default in Configuration.tmpl.
8158 *) Bugs which were fixed:
8159 a) yet more mod_proxy bugs [Ben Laurie]
8160 b) CGI works again with inetd [Alexei Kosut]
8161 c) Leading colons were stripped from passwords [osm@interguide.com]
8162 d) Another fix to multi-method Limit problem [jk@tools.de]
8164 Changes with Apache 1.1b4
8166 *) r->bytes_sent variable restored. [Robert Thau]
8168 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
8170 *) More possibly unsecure programs removed from the support directory.
8172 *) More mod_auth_msql authentication improvements.
8174 *) VirtualHosts based on Host: headers no longer conflict with the
8177 *) OS/2 compatibility enhancements. [Gary Smiley]
8179 *) POST now allowed to directory index CGI scripts.
8181 *) Actions now work with files of the default type.
8183 *) Bugs which were fixed:
8184 a) more mod_proxy bugs
8185 b) early termination of inetd requests
8186 c) compile warnings on several systems
8187 d) problems when scripts stop reading output early
8189 Changes with Apache 1.1b3
8191 *) Much of cgi-bin and all of cgi-src has been removed, due to
8192 various security holes found and that we could no longer support
8195 *) The "Set-Cookie" header is now special-cased to not merge multiple
8196 instances, since certain popular browsers can not handle multiple
8197 Set-Cookie instructions in a single header. [Paul Sutton]
8199 *) rprintf() added to buffer code, occurrences of sprintf removed.
8202 *) CONNECT method for proxy module, which means tunneling SSL should work.
8203 (No crypto needed) Also a NoCache config directive.
8205 *) Several API additions: pstrndup(), table_unset() and get_token()
8206 functions now available to modules.
8208 *) mod_imap fixups, in particular Location: headers are now complete
8211 *) New "info" module which reports on installed module set through a
8212 special URL, a la mod_status.
8214 *) "ServerPath" directive added - allows for graceful transition
8215 for Host:-header-based virtual hosts.
8217 *) Anonymous authentication module improvements.
8219 *) MSQL authentication module improvements.
8221 *) Status module design improved - output now table-based. [Ben Laurie]
8223 *) htdigest utility included for use with digest authentication
8226 *) mod_negotiation: Accept values with wildcards to be treated with
8227 less priority than those without wildcards at the same quality
8228 value. [Alexei Kosut]
8230 *) Bugs which were fixed:
8231 a) numerous mod_proxy bugs
8232 b) CGI early-termination bug [Ben Laurie]
8233 c) Keepalives not working with virtual hosts
8234 d) RefererIgnore problems
8235 e) closing fd's twice in mod_include (causing core dumps on
8236 Linux and elsewhere).
8238 Changes with Apache 1.1b2
8241 a) core dumps in mod_digest
8242 b) truncated hostnames/ip address in the logs
8243 c) relative URL's in mod_imap map files
8245 Changes with Apache 1.1b1
8247 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
8249 Changes with Apache 1.0.3
8251 *) Internal redirects which occur in mod_dir.c now preserve the
8252 query portion of a request (the bit after the question mark).
8255 *) Escape active characters '<', '>' and '&' in html output in
8256 directory listings, error messages and redirection links.
8259 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
8261 *) Fix for POSIX compliance in waiting for processes in alloc.c.
8264 *) setsockopt no longer takes a const declared argument [Martijn Koster]
8266 *) Reset timeout timer after each successful fwrite() to the network.
8267 This patch adds a reset_timeout() procedure that is called by
8268 send_fd() to reset the timeout ever time data is written to the net.
8271 *) timeout() signal handler now checks for SIGPIPE and reports
8272 lost connections in a more user friendly way. [Rob Hartill]
8274 *) Location of the "scoreboard" file which used to live in /tmp is
8275 now configurable (for OSes that can't use mmap) via ScoreBoardFile
8276 which works similar to PidFile (in httpd.conf) [Rob Hartill]
8278 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
8280 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
8281 which caused a SEGV with cookies enabled
8283 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
8286 *) Log the UNIX textual error returned by some system calls, in
8287 particular errors from accept() [David Robinson]
8289 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
8291 Changes with Apache 1.0.2
8293 *) patch to get Apache compiled on UnixWare 2.x, recommended as
8294 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
8296 *) Fix get_basic_auth_pw() to set the auth_type of the request.
8299 *) past changes to http_config.c to only use the
8300 setrlimit function on systems defining RLIMIT_NOFILE
8301 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
8302 for SUNOS and prototypes the needed functions.
8304 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
8307 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
8309 *) Merge multiple headers from CGI scripts instead of taking last
8310 one. [David Robinson]
8312 *) Add support for SCO 5. [Ben Laurie]
8314 Changes with Apache 1.0.1
8316 *) Silence mod_log_referer and mod_log_agent if not configured
8319 *) Recursive includes can occur if the client supplies PATH_INFO data
8320 and the server provider uses relative links; as file.html
8321 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
8323 *) The replacement for initgroups() did not call {set,end}grent(). This
8324 had two implications: if anything else used getgrent(), then
8325 initgroups() would fail, and it was consuming a file descriptor.
8328 *) On heavily loaded servers it was possible for the scoreboard to get
8329 out of sync with reality, as a result of a race condition.
8330 The observed symptoms are far more Apaches running than should
8331 be, and heavy system loads, generally followed by catastrophic
8332 system failure. [Ben Laurie]
8334 *) Fix typo in license. [David Robinson]
8336 Changes with Apache 1.0.0 23 Nov 1995
8338 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
8340 Changes with Apache 0.8.16 05 Nov 1995
8342 *) New man page for 'httpd' added to support directory [David Robinson]
8344 *) .htgroup files can have more than one line giving members for a
8345 given group (each must have the group name in front), for NCSA
8346 back-compatibility [Robert Thau]
8348 *) Mutual exclusion around accept() is on by default for SVR4 systems
8349 generally, since they generally can't handle multiple processes in
8350 accept() on the same socket. This should cure flaky behavior on
8351 a lot of those systems. [David Robinson]
8353 *) AddType, AddEncoding, and AddLanguage directives take multiple
8354 extensions on a single command line [David Robinson]
8356 *) UserDir can be disabled for a given virtual host by saying
8357 "UserDir disabled" in the <VirtualHost> section --- it was a bug
8358 that this didn't work. [David Robinson]
8360 *) Compiles on QNX [Ben Laurie]
8362 *) Corrected parsing of ctime time format [David Robinson]
8364 *) httpd does a perror() before exiting if it can't log its pid
8365 to the PidFile, to make diagnosing the error a bit easier.
8368 *) <!--#include file="..."--> can no longer include files in the
8369 parent directory, for NCSA back-compatibility. [David Robinson]
8371 *) '~' is *not* escaped in URIs generated for directory listings
8374 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
8376 *) Fixed bug involving handling URIs with escaped %-characters
8377 in redirects [David Robinson]
8379 Changes with Apache 0.8.15 14 Oct 1995
8381 *) Switched to new, simpler license
8383 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
8385 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
8387 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
8389 *) Correctly handles internal redirects to files with names containing '%'
8392 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
8394 *) Use geteuid() rather than getuid() to see if we have root privilege,
8395 so that server correctly resets privilege if run setuid root. [Andrew
8398 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
8401 *) Fix relative URLs in imagemap files [Randy Terbush]
8403 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
8406 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
8407 entries all name the same one. [David Robinson]
8409 *) Fix directory listings with filenames containing unusual characters
8412 *) Better URI-escaping for generated URIs in directories with filenames
8413 containing unusual characters [Ben Laurie]
8415 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
8417 *) Unblock alarms on error return from spawn_child() [David Robinson]
8419 *) Sample Config files have extra note for SCO users [Ben Laurie]
8421 *) Configuration has note for HP-UX users [Rob Hartill]
8423 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
8425 *) Nuked bogus #define in httpd.h [David Robinson]
8427 *) Better test for whether a system has setrlimit() [David Robinson]
8429 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
8431 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
8434 Changes with Apache 0.8.14 19 Sep 1995
8436 *) Compiles on SCO ODT 3.0 [Ben Laurie]
8438 *) AddDescription works (better) [Ben Laurie]
8440 *) Leaves an intelligible error diagnostic when it can't set group
8441 privileges on standalone startup [Andrew Wilson]
8443 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
8444 that machine, which claims to be BSD but does not support RLIMIT.
8447 *) gcc -Wall no longer complains about an unused variable when util.c
8448 is compiled with -DMINIMAL_DNS [Andrew Wilson]
8450 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
8452 Changes with Apache 0.8.13 07 Sep 1995
8454 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
8456 *) Have built-in imagemap code recognize & honor Point directive [James
8459 *) Generate cleaner directory listings in directories with a mix of
8460 long and short filenames [Rob Hartill]
8462 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
8464 *) Properly default ServerName for virtual servers [Robert Thau]
8466 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
8467 Paul Richards and a cast of thousands...]
8469 *) On self-identified BSD systems (we don't try to guess any more),
8470 allocate a few extra file descriptors per virtual host with setrlimit,
8471 if we can, to avoid running out. [Randy Terbush]
8473 *) Write 22-character lock file name into buffer with enough space
8474 on startup [Konstantin Olchanski]
8476 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
8479 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
8481 *) Suppress -Wall warning by initializing variable in negotiation code
8482 [Tobias Weingartner]
8484 Changes with Apache 0.8.12 31 Aug 1995
8486 *) Doesn't pause three seconds after including a CGI script which is
8487 too slow to die off (this is done by not even trying to kill off
8488 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
8489 after the entire document has been processed). [Robert Thau]
8491 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
8493 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
8495 *) Allows .htaccess files to override <Directory> sections naming the
8496 same directory [David Robinson]
8498 *) Removed an efficiency hack in sub_req_lookup_uri which was
8499 causing certain extremely marginal cases (e.g., ScriptAlias of a
8500 *particular* index.html file) to fail. [David Robinson]
8502 *) Doesn't log an error when the requested URI requires
8503 authentication, but no auth header line was supplied by the
8504 client; this is a normal condition (the client doesn't no auth is
8505 needed here yet). [Robert Thau]
8507 *) Behaves more sanely when the name server loses its mind [Sean Welch]
8509 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
8511 *) RFC931 code no longer passes out name of prior clients on current
8512 requests if the current request came from a server that doesn't
8513 do RFC931. [David Robinson]
8515 *) Configuration script accepts "Module" lines with trailing whitespace.
8518 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
8520 *) Cleaned up comments in mod_cgi.c [Robert Thau]
8522 Changes with Apache 0.8.11 24 Aug 1995
8524 *) Wildcard <Directory> specifications work. [Robert Thau]
8526 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
8528 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
8529 the file being requested itself, in addition to the directories leading
8530 up to it. [Robert Thau]
8532 *) Logs access failures due to symlink checks or invalid client address
8533 in the error log [Roy Fielding, Robert Thau]
8535 *) Symlink checks deal correctly with systems where lstat of
8536 "/path/to/some/link/" follows the link. [Thau, Fielding]
8538 *) Doesn't reset DirectoryIndex to 'index.html' when
8539 other directory options are set in a .htaccess file. [Robert Thau]
8541 *) Clarified init code and nuked bogus warning in mod_access.c
8544 *) Corrected several directives in sample srm.conf
8545 --- includes corrections to directory indexing icon-related directives
8546 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
8547 icons for encodings right, and turning on AddEncoding by default).
8550 *) Corrected descriptions of args to AddIcon and AddAlt in command table
8553 *) INSTALL & README mention "contributed modules" directory [Brian
8556 *) Fixed English in the license language... "for for" --> "for".
8559 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
8560 mod_alias.c, merging it almost completely with handling of Alias, and
8561 adding a 'notes' field to the request_rec which allows the CGI module
8562 to discover whether the Alias module has put this request through
8563 ScriptAlias (which it needs to know for back-compatibility, as the old
8564 NCSA code did not check Options ExecCGI in ScriptAlias directories).
8567 Changes with Apache 0.8.10 18 Aug 1995
8569 *) AllowOverride applies to the named directory, and not just
8570 subdirectories. [David Robinson]
8572 *) Do locking for accept() exclusion (on systems that need it)
8573 using a special file created for the purpose in /usr/tmp, and
8574 not the error log; using the error log causes real problems
8575 if it's NFS-mounted; this is known to be the cause of a whole
8576 lot of "server hang" problems with Solaris. [David Robinson;
8577 thanks to Merten Schumann for help diagnosing the problem].
8579 Changes with Apache 0.8.9 12 Aug 1995
8581 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
8583 *) Nested includes see environment variables of the including document,
8584 for NCSA bug-compatibility (some sites have standard footer includes
8585 which try to print out the last-modified date). [Eric Hagberg/Robert
8588 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
8589 URI as a CGI script, even if it would have been treated as something
8590 else if requested directly, for NCSA back-compatibility. (Note that
8591 this means that people who know the name of the script can see the
8592 code just by asking for it). [Robert Thau]
8594 *) New version of dbmmanage script included in support directory as
8597 *) Check if scoreboard file couldn't be opened, and say so, rather
8598 then going insane [David Robinson]
8600 *) POST to CGI works on A/UX [Jim Jagielski]
8602 *) AddIcon and AddAlt commands work properly [Rob Hartill]
8604 *) NCSA server push works properly --- the Arena bug compatibility
8605 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
8606 if you still want the workaround). [Rob Hartill]
8608 *) If client didn't submit any Accept-encodings, ignore encodings in
8609 content negotiation. (NB this will all have to be reworked anyway
8610 for the new HTTP draft). [Florent Guillaume]
8612 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
8614 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
8616 *) Give Redirect priority over Alias, for NCSA bug compatibility
8619 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
8620 paralleling earlier bug fix for CGI [David Robinson]
8622 *) If DBM auth is improperly configured, report a server error and don't
8625 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
8626 it seems to work well enough without it (even in a 10 hits/sec
8627 workout), and the overhead for the locking under A/UX is
8628 alarmingly high (though it is very low on other systems).
8629 [Eric Hagberg, Jim Jagielski]
8631 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
8633 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
8634 Behlendorf/Eric Hagberg]
8636 *) More improvements to default Configuration for A/UX [Jim Jagielski]
8638 *) Compiles clean on NEXT [Rob Hartill]
8640 *) Compiles clean on SGI [Robert Thau]
8642 Changes with Apache 0.8.8 08 Aug 1995
8644 *) SunOS library prototypes now never included unless explicitly
8645 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
8646 people using GNU libc on SunOS are screwed by prototypes for the
8649 (Those who wish to compile clean with gcc -Wall on a standard
8650 SunOS setup need the prototypes, and may obtain them using
8651 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
8652 with nonstandard libraries are presumably competent to make their
8655 *) Strips trailing '/' characters off both args to the Alias command,
8656 to make 'Alias /foo/ /bar/' work.
8658 Changes with Apache 0.8.7 03 Aug 1995
8660 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
8661 [reported by David Robinson]
8663 *) Compiles clean on OSF/1 [David Robinson]
8665 *) Added some of the more recent significant changes (AddLanguage stuff,
8666 experimental LogFormat support) to CHANGES file in distribution root
8669 Changes with Apache 0.8.6 02 Aug 1995
8671 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
8672 (If you actually wanted a conditional GET which bypassed the cache, you
8673 couldn't get it). [Reported by Roy Fielding]
8675 *) Properly terminate headers on '304 Not Modified' replies to conditional
8676 GETs --- no browser we can find cares much, but the CERN proxy chokes.
8677 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
8679 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
8681 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
8682 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
8683 and older versions don't set the __SUNPRO_C preprocessor variable). On
8684 all other systems, these are never used anyway. [Reported by Mark Cox].
8686 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
8688 Changes with Apache 0.8.5 01 Aug 1995
8690 *) Added last-minute configurable log experiment, as optional module
8692 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
8693 properly. (One-line fix to http_protocol.c).
8695 *) Work around bogus behavior when reloading from Netscape.
8696 It's Netscape's bug --- for some reason they expect a request with
8697 If-modified-since: to not function as a conditional GET if it also
8698 comes with Pragma: no-cache, which is way out of line with the HTTP
8699 spec (according to Roy Fielding, the redactor).
8701 *) Added parameter to set maximum number of server processes.
8703 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
8706 *) IdentityCheck bugfix [Chuck Murcko].
8708 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
8710 *) More sample config file corrections; add extension to AddType for
8711 *.asis, move AddType generic description to its proper place, and
8712 fix miscellaneous typos. [ Alexei Kosut ]
8714 *) Deleted the *other* reference to the regents from the Berkeley
8715 legal disclaimer (everyplace).
8717 *) Nuked Shambhala name from src/README; had already cleaned it out
8720 Changes with Apache 0.8.4
8722 *) Changes to server-pool management parms --- renamed current
8723 StartServers to MinSpareServers, created separate StartServers
8724 parameter which means what it says, and renamed MaxServers to
8725 MaxSpareServers (though the old name still works, for NCSA 1.4
8726 back-compatibility). The old names were generally regarded as
8727 too confusing. Also altered "docs" in sample config files.
8729 *) More improvements to default config files ---
8730 sample directives (commented out) for XBitHack, BindAddress,
8731 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
8732 defaults, AddTypes for send-as-is and imagemap magic types, and
8733 improvements to samples for DirectoryIndex [Alexei Kosut]
8735 *) Yet more improvements to default config files --- changes to
8736 Alexei's sample AddLanguage directives, and sample LanguagePriority
8737 [ Florent Guillaume ]
8739 *) Set config file locations properly if not set in httpd.conf
8742 *) Don't escape URIs in internal redirects multiple times; don't
8743 do that when translating PATH_INFO to PATH_TRANSLATED either.
8746 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
8748 Changes with Apache 0.8.3
8750 *) Edited distribution README to *briefly* summarize installation
8751 procedures, and give a pointer to the INSTALL file in the src/
8754 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
8755 recent NCSA distributions.
8757 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
8758 exist for the same directory, use both and don't segfault. [Reported
8761 *) Proper makefile dependencies [David Robinson]
8763 *) Note (re)starts in error log --- reported by Rob Hartill.
8765 *) Only call no2slash() after get_path_info() has been done, to
8766 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
8767 reported by Andrew Wilson, though this one is probably a real bug]
8769 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
8770 dump core when Referer is not supplied. [Randy Terbush]
8772 *) Lightly edited sample config files to refer people to our documentation
8773 instead of NCSA's, and to list Rob McCool as *original* author (also
8774 deleted his old, and no doubt non-functional email address). Would be
8775 nice to have examples of new features...
8777 Changes with Apache 0.8.2 19 Jul 1995
8779 *) Added AddLanuage code [Florent Guillaume]
8781 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
8783 *) All sorts of problems when MultiViews finds a directory. It would
8784 be nice if mod_dir.c was robust enough to handle that, but for now,
8785 just punt. [reported by Brian Behlendorf]
8787 *) Wait for all children on restart, to make sure that the old socket
8788 is gone and we can reopen it. [reported by Randy Terbush]
8790 *) Imagemap module is enabled in default Configuration
8792 *) RefererLog and UserAgentLog modules properly default the logfile
8795 *) Mark Cox's mod_cookies added to the distribution as an optional
8796 module (commented out in the default Configuration, and noted as
8797 an experiment, along with mod_dld). [Mark Cox]
8799 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
8801 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
8803 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
8805 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
8808 Changes with Apache 0.8.1
8810 *) New imagemap module [Randy Terbush]
8812 *) Replacement referer log module with NCSA-compatible RefererIgnore
8813 [Matthew Gray again]
8815 *) Don't mung directory listings with very long filenames.
8818 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
8820 *) New config script. See INSTALL for info. [Robert Thau]
8822 *) Scoreboard mechanism for regulating the number of extant server
8823 processes. MaxServers and StartServers defaults are the same as
8824 for NCSA, but the meanings are slightly different. (Actually,
8825 I should probably lower the MaxServers default to 10).
8827 Before asking for a new connection, each server process checks
8828 the number of other servers which are also waiting for a
8829 connection. If there are more than MaxServers, it quietly dies
8830 off. Conversely, every second, the root, or caretaker, process
8831 looks to see how many servers are waiting for a new connection;
8832 if there are fewer than StartServers, it starts a new one. This
8833 does not depend on the number of server processes already extant.
8834 The accounting is arranged through a "scoreboard" file, named
8835 /tmp/htstatus.*, on which each process has an independent file
8836 descriptor (they need to seek without interference).
8838 The end effect is that MaxServers is the maximum number of
8839 servers on an *inactive* server machine, but more will be forked
8840 off to handle unusually heavy loads (or unusually slow clients);
8841 these will die off when they are no longer needed --- without
8842 reverting to the overhead of full forking operation. There is a
8843 hard maximum of 150 server processes compiled in, largely to
8844 avoid forking out of control and dragging the machine down.
8845 (This is arguably too high).
8847 In my server endurance tests, this mechanism did not appear to
8848 impose any significant overhead, even after I forced it to put the
8849 scoreboard file on a normal filesystem (which might have more
8850 overhead than tmpfs). [Robert Thau]
8852 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
8855 *) Read .htaccess files even in directory with <Directory> section.
8856 (Former incompatibility noted on mailing list, now fixed). [Robert
8859 *) "HEAD /" gives the client a "Bad Request" error message, rather
8860 than trying to send no body *and* no headers. [Cliff Skolnick].
8862 *) Don't produce double error reports for some very obscure cases
8863 mainly involving auth configuration (the "all modules decline to
8864 handle" case which is a sure sign of a server bug in most cases,
8865 but also happens when authentication is badly misconfigured).
8868 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
8869 it's *for*, and this sort of thing really shouldn't be cluttering
8870 up the Makefile). [Robert Thau]
8872 *) Incidental code cleanups in http_main.c --- stop dragging
8873 sa_client around; just declare it where used. [Robert Thau]
8875 *) Another acc-related fix. (It doesn't like const char
8876 in some places...). [Mark Cox]
8878 Changes with Shambhala 0.6.1 13 Jul 1995
8880 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
8881 Also, fixed auth typo in http_protocol.c unmasked by this fix.
8883 *) Compiles clean with acc on SunOS [Paul Sutton]
8885 *) Reordered modules in modules.c so that Redirect takes priority
8886 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
8887 believe it or not, he has an actual site with a ScriptAlias and
8888 a Redirect declared for the *exact same directory*. Even *my*
8889 compatibility fetish wouldn't motivate me to fix this if the fix
8890 required any effort, but it doesn't, so what the hey.
8892 *) Fixed to properly default several server_rec fields for virtual
8893 servers from the corresponding fields in the main server_rec.
8894 [Cliff Skolnick --- 'port' was a particular irritant].
8896 *) No longer kills off nph- child processes before they are
8897 finished sending output. [Matthew Gray]
8899 Changes with Shambhala 0.6.0 10 Jul 1995
8901 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
8902 the connection to the client in an "aborted" state, but otherwise
8903 allow whatever handlers are running to clean up. hard_timeout()s
8904 abort the request in progress completely; anything not tied to some
8905 resource pool cleanup will leak. They're still around because I
8906 haven't yet come up with a more elegant way of handling
8907 timeouts when talking to something that isn't the client. The
8908 default_handler and the dir_handler now use soft timeouts, largely
8909 so I can test the feature. [Robert Thau]
8911 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
8912 the case of log handlers dying prematurely is probably handled VERY
8913 gracelessly at this point, and if the logger stops reading input,
8914 the server will hang. (It is known to correctly restart the
8915 logging process on server restart; this is (should be!) going through
8916 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
8917 script). [Robert Thau]
8919 *) asis files supported (new module). [Robert Thau]
8921 *) IdentityCheck code is compiled in, but has not been tested. (I
8922 don't know anyone who runs identd). [Robert Thau]
8924 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
8925 came in with the request, for NCSA bug-compatibility. [Robert Thau]
8927 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
8929 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
8930 as timeouts are not in scope. [Robert Thau]
8932 *) quoted-string args in config files now handled correctly (doesn't drop
8933 the last character). [Robert Thau; reported by Randy Terbush]
8935 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
8936 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
8938 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
8939 default default type); the former default default behavior when all
8940 type-checkers defaulted had been a core dump. [Paul Sutton]
8942 *) Copy filenames out of the struct dirent when indexing
8943 directories. (On Linux, readdir() returns a pointer to the same
8944 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
8946 Changes with Shambhala 0.5.3 [not released]
8948 *) Default response handler notes "file not found" in the error log,
8949 if the file was not found. [Cliff Skolnick].
8951 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
8952 code no longer sets up bogus PATH_INFO which fakes out the directory
8953 handler). [Cliff Skolnick]
8955 Changes with Shambhala 0.5.2 06 Jul 1995
8957 *) Changes to http_main.c --- root server no longer plays silly
8958 games with SIGCHLD, and so now detects and replaces dying
8959 children. Child processes just die on SIGTERM, without taking
8960 the whole process group with them. Potential problem --- if any
8961 child process refuses to die, we hang in restart.
8962 MaxRequestsPerChild may still not work, but it certainly works
8963 better than it did before this! [Robert Thau]
8965 *) mod_dir.c bug fixes: ReadmeName and HeaderName
8966 work (or work better, at least); over-long description lines
8967 properly terminated. [Mark Cox]
8969 *) http_request.c now calls unescape_url() more places where it
8970 should [Paul Sutton].
8972 *) More directory handling bugs (reported by Cox)
8973 Parent Directory link is now set correctly. [Robert Thau]
8975 Changes with Shambhala 0.5.1 04 Jul 1995
8977 *) Generalized cleanup interface in alloc.c --- any function can be
8978 registered with alloc.c as a cleanup for a resource pool;
8979 tracking of files and file descriptors has been reimplemented in
8980 terms of this interface, so I can give it some sort of a test.
8983 *) More changes in alloc.c --- new cleanup_for_exec() function,
8984 which tracks down and closes all file descriptors which have been
8985 registered with the alloc.c machinery before the server exec()s a
8986 child process for CGI or <!--#exec-->. CGI children now get
8987 started with exactly three file descriptors open. Hopefully,
8988 this cures the problem Rob H. was having with overly persistent
8989 CGI connections. [Robert Thau]
8991 *) Mutual exclusion around the accept() in child_main() --- this is
8992 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
8993 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
8994 This uses fcntl(F_SETLK,...) on the error log descriptor because
8995 flock() on that descriptor won't work on systems which have BSD
8996 flock() semantics, including (I think) Linux 1.3 and Solaris.
8998 This does work on SunOS (when the server is idle, only one
8999 process in the pool is waiting on accept()); it *ought* to work
9000 on the other systems. [Robert Thau]
9002 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
9004 *) sizeof(*sa_client) bugfix from [Rob Hartill]
9006 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
9008 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
9009 be unnecessary if I go to the revised timeout-handling scheme).
9012 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
9013 string) even if none came in with the request. [Robert Thau]
9015 *) CHANGES file added to distribution ;-).
9017 Changes with Shambhala 0.4.5
9019 *) mod_dld --- early dynamic loading support [rst]
9020 *) Add wildcard content handlers for XBITHACK; default_hander now
9021 invoked with that mechanism (as a handler hanging off mod_core) [rst]
9022 *) XBITHACK supported as a wildcard content-handler, and
9023 configurable at run-time (not just at compile time, as in the
9024 "patchy server" releases) [rst]
9026 Changes with Shambhala 0.4.4 30 Jun 1995
9028 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
9029 *) Handle Addtype x/y .z [rst, reported by Cox]
9031 Changes with Shambhala 0.4.3
9033 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
9034 synonymous [rst, terbush]
9036 Changes with Shambhala 0.4.1 28 Jun 1995
9038 *) First-cut virtual host implementation; some refit in the config
9039 reading code, and log management, was necessary to support this [rst]
9040 *) Sub-pool machinery, originally added to avoid excessive storage
9041 allocation on listings of large directories (which turned out to
9042 be the problem that the 0.3 storage accounting was added to
9043 find). Subrequests and mod_dir changed to use subpools. [rst]
9044 *) More memory debugging --- free list consistency checks. [rst]
9045 *) Added err_headers to request_rec, with support elsewhere [rst]
9046 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
9048 Changes with Shambhala 0.3 19 Jun 1995
9050 *) Switch ONE_PROCESS to a runtime command-line option (-X)
9051 *) Don't compile in mod_ai_backcompat by default
9052 *) Switch name of server from Apache to Shambhala in Makefile
9053 *) Add some accounting routines to track memory usage in the pools,
9056 Changes with Shambhala 0.2
9058 *) Set DOCUMENT_ROOT CGI variable
9059 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
9060 *) Add critical section protection to handling of cleanup structures
9062 *) Significant code reorg within the server core to group related
9063 functions together [rst]
9064 *) Correctly handle clients that hang up before sending any request
9066 *) Replace dying child processes. [rst]
9068 Changes with Shambhala 0.1 12 Jun 1995
9070 Major rewrite of the pre-existing "patchy server" codebase, by
9071 Robert Thau (rst). Significant portions of the server code, such
9072 as configuration-file handling and HTTP authentication support,
9073 were ripped out and rewritten from scratch. Code that was not
9074 completely rewritten was significantly altered.
9076 Major changes with this release include:
9078 *) Introduction of the module API; in request handling, the central
9079 machinery just dispatches to various modules, which actually do
9080 most of the work. Configuration handling is similar --- modules
9081 declare their own commands, and the central machinery just
9084 API features from shambhala/0.1 were substantially unchanged in
9085 Apache 1.0 and 1.1. (1.0 API features not yet present in this
9086 release, such as wildcard handlers and subpools, were added in
9087 subsequent Shambhala releases, and were also generally rst's
9090 *) This release included the following modules:
9092 mod_access (access control --- allow and deny directives),
9093 mod_alias (Alias and Redirect commands),
9094 mod_auth (straight HTTP authentication, based on flat-files)
9095 mod_auth_dbm (same, with dbm files)
9096 mod_cgi (CGI scripts and, in this release, ScriptAlias)
9097 mod_common_log (CLF access logs; later renamed mod_log_common)
9098 mod_dir (directory indexing)
9099 mod_include (server-side includes)
9100 mod_mime (AddType directives)
9101 mod_negotiation (content negotiation)
9102 mod_userdir (support for users' public_html directories)
9104 It also included a mod_ai_backcompat, which was a private hack
9105 for back-compatibility with rst's own AI-lab servers.
9107 All of these modules were substantially complete, and functional
9108 or nearly so (a few, which implemented features not in use at
9109 Thau's site, required patches of a few lines).
9111 *) sub-request machinery, to allow modules to determine how other
9112 modules would assign MIME types to a given file, or optionally
9113 serve its content (this is heavily used by mod_dir, mod_include
9114 and mod_negotiation).
9116 *) Resource pool system for keeping track of memory allocated and
9117 files opened in service of a particular request. Much of the
9118 code in the modules (when they weren't rewrites) was adjusted to
9119 replace a pervasive convention of using fixed-size buffers on
9120 the stack with an equally pervasive convention of using memory
9121 allocated with palloc().
9123 *) Reorganization of data structures associated with a given
9124 request to eliminate use of global variables and the troublesome
9125 unmunge_name function (used in NCSA and early Apache releases to
9126 attempt to determine the URI which mapped to a given filename
9127 --- a difficult proposition, given that it is easy to produce
9128 setups in which multiple URIs map to the same file).
9130 *) Source files renamed and rearranged
9132 *) Very simple pre-forking behavior --- parent process forked off a
9133 fixed number of children, and then just waited for SIGHUP.
9135 *) Other more minor changes too numerous to list.
9137 This release included modified versions of a lot of code from the
9138 Apache 0.6.4 public release, plus an early pre-forking patch
9139 codeveloped by Robert Thau and Rob Hartill.
9141 Changes with Apache 0.7.3 20 Jun 1995
9143 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
9144 were incorporated by Rob Hartill on the main branch while Robert Thau
9145 worked on the Shambhala rewrite above. Most were merged into the
9146 Shambala architecture after Apache 0.8.0.
9148 Changes with Apache 0.6.4 13 May 1995
9150 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
9153 Changes with Apache 0.5.1 10 Apr 1995
9155 Changes with Apache 0.4 02 Apr 1995
9157 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
9160 Changes with Apache 0.3 24 Mar 1995
9162 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
9165 Changes with Apache 0.2 18 Mar 1995
9167 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
9168 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
9169 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
