[Justin Erenkrantz] + + *) Introduce the MultiviewsMatch directive, to allow the operator + to be flexible in recognizing Handlers and Filters filename + extensions as part of the Multiviews matching logic, strict with + MultiviewsMatch NegotiatedOnly to accept only filename extentions + that designate negotiated parameters, (content type, charset, etc.) + or MultiviewsAll for the 1.3 behavior of matching any files, even + if they have unregistered extensions. [William Rowe] + + *) Fixed the configure script to add a LoadModule directive to + the default httpd.conf for any module that was compiled + as a DSO. [Aaron Bannert <aaron clove.org>] + + *) rewrite mod_ssl input filtering to work with the new input filtering + system. [Justin Erenkrantz] + + *) prefork: Don't segfault when we are able to listen on some but + not all of the configured ports. [Jeff Trawick] + + *) Build mod_so even if no core modules are built shared. + [Aaron Bannert <aaron clove.org>] + + *) Introduce ap_directory_walk rewrite (with further optimizations + required) to adapt to the ap_process_request_internal() changes. + Optimized so subrequests and redirects now reuse previous section + merges, until we mismatch with the original directory_walk, and + precomputed r->finfo results will cause directory_walk to skip + the most expensive phases of the function. [William Rowe] + + *) Allow ApacheMonitor to connect to and control Apache on other + WinNT/2K machines. [Mladen Turk <mturk mappingsoft.com>] + + *) Remove the Port directive. In it's place, the Listen directive + is now a required directive, which tells Apache what port to + listen on. The ServerName directive has also been extended + to accept an optional port. If the port is specified to the + ServerName, the server will report that port whenever it + reports the port that it is listening on. This change was + made to ease configuration errors that stem from having a Port + directive, and a Listen directive. In that situation, the server + would only listen to the port specified by the Listen command, + which caused a lot of confusion to users. [Ryan Bloom] + + *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32 + build, as loadable modules. [William Rowe] + + *) Fix --enable-mods-shared processing. If most is specified, + then all modules that can be compiled as shared modules are. + [Aaron Bannert <aaron clove.org>] + + *) Update the mime.types file to map video/vnd.mpegurl to mxu + and add commonly used audio/x-mpegurl for m3u extensions. + [Heiko Recktenwald <uzs106 uni-bonn.de>, Lars Eilebrecht] + + *) Eliminate the depreciated r->content_language, in favor of the array + r->content_languages introduced many years ago. Module authors must + substantially overhaul their modules, so this needs to be upgraded + if the module still relied on backwards-brokeness. [William Rowe] + + *) Allow configure help strings to work with autoconf 2.50+ and 2.13. + [Justin Erenkrantz] + + *) Rewrite the input filtering mechanisms to consolidate and reorganize + code. In short, core_input_filter does something now and + ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz] + + *) Update the Win32 build to re-absorb mod_proxy and family. + [William Rowe] + + *) Resolved the build failure on Win32 using MSVC 5.0 (without the + current SDK.) [William Rowe] + + *) Some style changes to the code that does ProxyErrorOverride. Fixed + config merge behaviour. [Graham Leggett] + + *) Allow support programs to be compiled against a static version + of libapr. This allows the smaller support programs to be + relocated. [Aaron Bannert <aaron clove.org>] + + *) Update the mime.types file to the registered media types as + of 2001-09-25, and add mapping for xsl extension [Mark Cox] + + *) Fix MaxClients in the Worker MPM, so that it specifies the maximum + number of clients that can connect at the same time, instead of + specifying the maximum number of child processes. + [Aaron Bannert <aaron clove.org>] + + *) Switch proc_pthread AcceptMutex configuration directive to pthread to + be consistent with 1.3. [Justin Erenkrantz] + + *) Cache apr_explode_localtime() value for 15 seconds. + [Brian Pane <bpane pacbell.net>] + + *) Fix mod_include to not return ETag or Last-Modified headers. + [Ian Holsman <ianh cnet.com>] + + *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron clove.org>] + + *) Eliminate the wasteful run-time conversion of method names from strings + to numbers in places where the methods are known at compile time. + [Brian Pane <bpane pacbell.net>] + + *) Turn the worker MPM's queue into a LIFO. This may + improve cache-hit performance under some conditions. + [Aaron Bannert <aaron clove.org>] + + *) Switch back to SIGUSR1 for graceful restarts on all platforms that + support it. [Justin Erenkrantz] + + *) Cleanup the worker MPM. We no longer re-use transaction + pools. This incurs less overhead than shuffling the pools + around so that they can be re-used. Remove one of the + queue's condition variables. We just redefined the API to + state that you can't try to add more stuff than you allocated + segments for. [Aaron Bannert <aaron clove.org>] + + *) Fix SSL VPATH builds [Cody Sherr <csherr covalent.net>] + + *) Fixed persistent connections when a request contains a body. + [Greg Stein] + + *) mod_dav uses a new API to speak to the backend provider for dead + property management. [Greg Stein] + + *) Remove the Win32 script-processing exception from mod_cgi, and + roll build_command_line/build_argv_list into a unified, overrideable + ap_cgi_build_command optional function. [William Rowe] + + *) Rewrite find_start_sequence to use a better search algorithm + to find the start tag. [Justin Erenkrantz] + + *) Fix a seg fault in mod_include. When we are generating an + internal redirect, we must set r->uri to "", not a bogus + string, and not NULL. [Ryan Bloom] + + *) Optimized location_walk, so subrequests, redirects and second passes + now reuse previous section merges on a <Location > by <Location > + basis, until we mismatch with the original location_walk. + [William Rowe] + + *) Back out the 1.45 change to util_script.c. This change made + us set the environment variable REQUEST_URI to the redirected + URI, instead of the originally requested URI. + [Taketo Kabe <kabe sra-tohoku.co.jp>] + + *) Make mod_include do lazy evaluation of potentially expensive to + compute variables. [Brian Pane <bpane pacbell.net>] + + *) Fix logging of bytes sent for HEAD requests. %b and %B should + log either - or 0, before this patch, they were both logging + the file size. [Taketo Kabe <kabe sra-tohoku.co.jp>] + + *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather + than per character. [Brian Pane <bpane pacbell.net>] + + *) Normalize the primary request, redirects and sub-requests to + run the same ap_process_request_internal for consistency in + robustness, behavior and security. [William Rowe] + + *) Fix a segfault with mod_include when r->path_info is not set + (which is the case with mod_proxy). [Ian Holsman <ianh cnet.com>] + + *) Add -X functionality back. This indicates to all MPMs and any other + part of Apache that it should run in "debug" mode. [Justin Erenkrantz] + + *) Some initial support for the cygwin platform [prefork only]. + This is not to be confused with support for the WinNT/Win32 + platform, which is the recommended configuration for native + Win32 users. The cygwin platform support is recommended for + cygwin platform users. [Stipe Tolj <tolj wapme-systems.de>] + + *) Changed syntax of Set{Input|Output}Filter. The list of filters + must be semicolon delimited (if more than one filter is given.) + The Set{Input|Output}Filter directive now overrides a parent + container's directive (e.g. SetInputFilter in <Directory /web/foo> + will override any SetInputFilter directive in <Directory /web>.) + This new syntax is more consistent with Add{Input|Output}Filter + directives defined in mod_mime. Also cures a bug in prior releases + where the Set{Input|Output}Filter directive would corrupt the + global configuration if the multiple directives were nested. + [William Rowe] + + *) Cured what's ailed mime for quite some time. If an AddSomething + was given in the configuration (Language, Charset, Handler or + Encoding) Apache would set the content type as given by AddType, + but refused to check the mime.types file if AddType wasn't given + for that specific extension. Setting the AddHandler for .html + without setting the AddType text/html html would cause Apache to + use the default content type. [William Rowe] + + *) Added some bulletproofing to memory allocation in the LDAP cache + code. [Graham Leggett] + +Changes with Apache 2.0.25 + + *) Move the installed /manual directory out of the /htdocs/ tree, so + that it can be kept more independently from the remaining document + root. The "Alias /manual ..." already allowed for easy projection + into existing private document trees. [Martin Kraemer] + + *) Add specified user attributes to the environment when using + mod_auth_ldap. This allows you to use mod_include to embed specified + user attributes in a page like so: + Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you? + [Graham Leggett] + + *) Fix a performance problem with the worker MPM. We now create + transaction pools once, and re-use them for each connection. + [Aaron Bannert <aaron clove.org>] + + *) Modfied mod_mime to prevent mod_negotation from serving a multiview + of a 'handler' or 'filter', so that any filename extension that does + not contribute to the negotiated metadata can't be served without + an explicit request. E.g., if the .Z extension is associated with + an unzip filter, the user request somefile.Z.html, mod_negotiation + won't serve it. It can serve somefile.Z.html when somefile.Z is + requested, since the .Z extension is explictly requested, if the + .html extension is associated with ContentType text/html. + [William Rowe] + + *) Introduce the AddInputFilter filter[;filter...] ext [ext...] + and corresponding AddOutputFilter syntax, to insert one or more + filters by mod_mime filename extension processing. + [William Rowe] + + *) Fix a growing connection pool in core_output_filter() for + keepalive requests. [Jeff Trawick] + + *) Moved split_and_pass_pretag_buckets back to being a + macro at Ryans's request. Removed the return from it + by setting and returning a return code instead. Updated + the code to check the return code from the macro and + do the right thing. [Paul J. Reder] + + *) Fix a segfault when a numeric value was received for Host:. + [Jeff Trawick] + + *) Add a function ap_remove_input_filter. This is to match + up with ap_remove_output_filter. [Ryan Bloom] + + *) Clean up location_walk, so that this step performs a minimum + amount of redundant effort (it must be run twice, but it will no + longer reparse all <Location > blocks when the request uri + hadn't changed.) [William Rowe] + + *) Eliminate proxy: (and all other 'special') processing from the + ap_directory_walk() phase. Modules that want to use special + walk logic should refer to the mod_proxy map_to_location example, + with it's proxy_walk and proxysection implementation. This makes + either directory_walk flavor much more legible, since that phase + only runs against real <Directory > blocks. + [William Rowe] + + *) SECURITY: Fix a security problem in mod_include which would allow + an SSI document to be passed to the client unparsed. + [Cliff Woolley, Brian Pane] + + *) Introduce the map_to_storage hook, which allows modules to bypass + the directory_walk and file_walk for non-file requests. TRACE + shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the + directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c. + [William Rowe] + + *) Add the ability for mod_include to add the INCLUDES filter + if the file is configured for the server-parsed handler. + This makes the configuration for .shtml files much easier + to understand, and allows mod_include to honor Apache 1.3 + config files. Based on Doug MacEachern's patch to PHP + to do the same thing. [Ryan Bloom] + + *) force OpenSSL to ignore process local-caching and to always + get/set/delete sessions using mod_ssl's callbacks + [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>, + Geoff Thorpe <geoff geoffthorpe.net>] + + *) Make the worker MPM shutdown and restart cleanly. This also + cleans up some race conditions, and gets the worker using + pools more cleanly. [Aaron Bannert <aaron clove.org>] + + *) Implement CRYPTO_set_locking_callback() in terms of apr_lock + for mod_ssl + [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>] + + *) Fix for mod_include. Ryan's patch to check error + codes put a return in the wrong place. Also, the + include handler return code wasn't being checked. + I don't like macros with returns, so I converted + SPLIT_AND_PASS_PRETAG_BUCKETS into a function. + [Paul J. Reder <rederpj raleigh.ibm.com>] + + *) fix segv in mod_mime if no AddTypes are configured + [John Sterling <sterling covalent.net>] + + *) Enable ssl client authentication at SSL_accept time + [Madhusudan Mathihalli <madhusudan_mathihalli hp.com>] + + *) Fix a segfault in mod_include when the original request has no + associated filename (e.g., we're filtering the error document for + a bad URI). [Jeff Trawick] + + *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick] + + *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy + of httpd is started and shuts down due to socket conflict. Moving the + call to ap_log_pid solves the problem. + + *) Changed the late-1.3 log_config substitution %c to %X, to log the + status of the closed connection, as it conflicts with the far more + common, historical ssl logging directive %...{var}c. [William Rowe] + + *) Added the common error/ tree to the build/install targets + (similar to the common icons/ tree) for the multi-language error + messages that Lars committed earlier. [William Rowe] + + *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard] + + *) Added a default commented-out mod_ldap and mod_auth_ldap + configuration to httpd-std.conf and httpd-win.conf + [Graham Leggett] + + *) Added documentation for mod_ldap and mod_auth_ldap. + [Graham Leggett] + + *) Enabled negative caching on attribute comparisons in the LDAP cache. + Fixed a problem where the default cache TTL was set in milliseconds + not microseconds causing the cache to time out almost immediately. + [Graham Leggett] + + *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP + module code to follow APR. [Graham Leggett] + + *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now + cleaned up when the connection pool pool is cleaned up. + [Graham Leggett] + + *) Fix a minor issue with Jeff Trawick's mod_include + patch. Without this patch, the code will just allocate + more bytes in get_combined_directive than are needed. + [Paul Reder] + + *) Added the LDAP authentication module mod_auth_ldap. + [Dave Carrigan <dave rudedog.org>, Graham Leggett] + + *) Added the LDAP cache and connection pooling module mod_ldap. + [Dave Carrigan <dave rudedog.org>, Graham Leggett] + + *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest + by allowing a module to disable itself if its prerequisites are not + met. [Justin Erenkrantz] + +Changes with Apache 2.0.24 + + *) Fix a couple of issues in mod_include when the tag appeared at + offsets near 8192 in the file being parsed. [Jeff Trawick] + + *) Fix an assertion failure in mod_ssl when the keepalive timeout is + reached. [Jeff Trawick] + + *) Numerous improvements to the Win32 build system. Introduced command line + builds without requiring .mak files for MSVC 6.0 and later versions. + Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users. + [William Rowe] + + *) Assorted corrections and improvements to the winnt_mpm startup code. Better + reporting of uninstalled services and other error conditions, and changed the + default service name to Apache2. [William Rowe] + + *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm + compatibility with existing Apache 1.3 Win32 Apache management utilites. + [Mladen Turk <mturk mappingsoft.com>, William Rowe] + + *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20. + [William Rowe, Greg Ames] + + *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage + and RemoveCharset directives. [William Rowe] + + *) The Unix MPMs other than perchild now allow child server + processes to use the accept mutex when starting as root and + using SysV sems for the accept mutex. Previously, this + combination would lead to fatal errors in the child server + processes. perchild can't use SysV sems because of security + issues. [Jeff Trawick, Greg Ames] + + *) Added Win32 revision stamp resources to all http binaries + (including modules/ and support/ tools.) PR7322 [William Rowe] + + *) Fix ap_rvprintf to support more than 4K of data at one time. + [Cody Sherr <csherr covalent.net>] + + *) We have always used the obsolete/deprecated Netscape syntax + for our tracking cookies; now the CookieStyle directive + allows the Webmaster to choose the Netscape, RFC2109, or + RFC2965 format. The new CookieDomain directive allows the + setting of the cookie's Domain= attribute, too. PR #s 5006, + 5023, 5920, 6140 [Ken Coar] + + *) Tweak server/Makefile so that the rules for generating exports.c + are compatible with make utilities which don't expand wildcards + in a dependency list (e.g., OS/390 make, certain levels of GNU + make). [Jeff Trawick] + + *) Install the SSL headers. [John Sterling <sterling covalent.net>] + + *) Begin to sanitize the MPM configuration directives. Now, all + MPMs use the same functions for all common MPM directives. This + should make it easier to catch all bugs in these directives once. + [Cody Sherr <csherr covalent.net>] + + *) Close a major resource leak. Every time we had issued a + graceful restart, we leaked a socket descriptor. + [Ryan Bloom] + + *) Fix a problem with the new method code. We need to cast + the 1 to an apr_int64_t or it will be treated as a 32-bit + integer, and it will wrap after being shifted 32 times. + [Cody Sherr <csherr covalent.net> and Ryan Morgan <rmorgan covalent.net>] + + *) Fix a bug in mod_expires. Previous to this patch, if you + told mod_expires to add 604800 seconds to the last-modified + time, it actually added 604800 usec's to the last-modified time, + so that when looking at the response it looked like nothing + had been done. The root of the problem was that we always compute + time in usec's, but we ask users to input sec's. This means we + need to convert to usec's before using those values. + [Ryan Bloom] + + *) The worker MPM now handles shutdown and restart requests. It + definitely isn't perfect, but we do stop the servers correctly. + The biggest problem right now is that SIGHUP causes the server to + just die. [Ryan Bloom] + +Changes with Apache 2.0.23 + + *) Use the prefork MPM by default on Unix. [various] + + *) Added a systray icon monitor application for Win32. + [Mladen Turk <mturk mappingsoft.com>] + + *) mod_rewrite: Fix the line ending on some non-Unix systems for + messages written to the rewrite log. + [Richard Labennett <rlabenn us.ibm.com>] + + *) All mod_autoindex query parsing is now quietly quashed with the + IndexOption IgnoreClient. The IndexOption SuppressColumnSorting + still drops the column sort <a href>'s for the column headers, but + IgnoreClient is required to ignore these Query options entirely. + [William Rowe] + + *) Introduced new mod_autoindex query argument parsing for F=[0|1|2] + to allow the client to select plain, FancyIndexing or HTMLTable + formatting, V=[0|1] to inhibit or enable version sorting, and + P=pattern to return only specific files. The old Query Arguments + were reorganized as C=f for sorting column 'f' (same N, D, S, or M + as before), and O=A|D for ordering ascending or descending. + [William Rowe] + + *) Fixed an error in mod_include's directive parsing routines which + caused #if, #elif, and #else expressions containing backslashes + to be improperly evaluated. [Cliff Woolley] + + *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to + drop the icon column, SuppressRules to drop the <hr> elements, + and HTMLTable to create rudimentary HTML table listings (implies + FancyIndexing). [William Rowe] + + *) Re-introduced the mod_autoindex IndexOptions flag TrackModified + from Apache 1.3.15. This is needed for two reasons, first, given + multiple machines within a server farm, ETags and Last-Modified + stamps won't correspond from machine to machine, and second, many + Unixes don't capture changes to the date or time stamp of existing + files, since these don't modify the dirent itself. [William Rowe] + + *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst + and DirectoryWidth options from Apache 1.3.10. + [William Rowe, Ken Coar] + + *) Eliminated FancyIndexing directive, deprecated early in Apache + 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe] + + *) mod_autoindex now excludes any file names that would result in + an error, other than a success or redirect. Also optimized + the parent directory, always included except in the URI '/'. + [William Rowe] + + *) Refactored mod_negotiation and mod_mime to help mod_dir accept + negotiated index pages, and prevent the server from defaulting + to an autoindex of the directory. mod_negotiation will now die + with a 500 Internal Error if it could match some filenames + (e.g. for mod_dir) but none can be served. mod_negotation now + refuses to serve any file with an extention that mod_mime doesn't + recognize, and wasn't part of the request. [William Rowe] + + *) Eliminate mod_cgi's handling of .exe files without the .exe file + extension. This is already handled by multiviews, if the admin + wishes to AddHandler .exe or define a content type handler and + associate .exe files with that content type. Multiviews must be + enabled to allow these to be served. [William Rowe] + + *) Speed up the server's response to a spike in incoming workload + or restarts by assigning empty scoreboard slots to new processes + when they are available. [Greg Ames] + + *) Add a handler to mod_includes.c. This handler is designed to + implement the XbitHack directive. This can't be done with a + fixup, because we need to check the content-type, which is + only available in the handler phase. [Ryan Bloom] + + *) Make the includes filter check return codes from filters lower in + the filter chain. If a lower level filter returns an error, then + the request needs to stop immediately. This allows mod_include to + stop parsing data once a lower filter recognizes an error. + [Ryan Bloom] + + *) Add the ability to extend the methods that Apache understands + and have those methods <limit>able in the httpd.conf. It uses + the same bit mask/shifted offset as the original HTTP methods + such as M_GET or M_POST, but expands the total bits from an int to + an ap_int64_t to handle more bits for new request methods than + an int provides. [Cody Sherr <csherr covalent.net>] + + *) Fix broken mod_mime behavior in merging its arguments. Possible + cause of unexplicable crashes introduced in 2.0.20. [William Rowe] + + *) Solve many mod_ssl porting issues (too many to detail) with + help from the whole team, but most notably [Ralf S. Engelschall, + Madhusudan Mathihalli <madhusudan_mathihalli hp.com>, + Doug MacEachern, William Rowe, Cliff Woolley] + + *) More stall fixes for the threaded & worker mpm's. + Make mod_status output more accurate. Don't + count workers in processes which aren't actively + serving requests. [Greg Ames] + + *) Win32: Get SSI exec cgi tag working. [Bill Stoddard] + + *) Add a single listener/multiple worker MPM. This MPM is + definately not fully correct, but it allows us to solve many + of the problems that exist in the threaded MPM. This is a + modified version of the threaded MPM. [Ryan Bloom] + + *) Improve content generation throughout Apache, providing closer + compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0 + Transitional specifications. [William Rowe] + +Changes with Apache 2.0.22 + + *) Fix a problem where the threaded MPM stalls after restarts or + segfaults. Also prevent multiple active processes from using + the same scoreboard slot. [Greg Ames] + + *) Apache/Win32 now fills in the service description with Apache's + server version string, including loaded and advertised modules. + [William Rowe] + + *) Improved support for the Win32 build, to recover gracefully from + missing apr or apr-util directories or the awk interpreter, + create the proper cgi-bin examples, including a test-cgi.bat, and + fix the perl shebang line for printenv.pl, when installing from + the build environment. [William Rowe] + + *) Fix a segfault in threaded.c caused by passing uninitialized + apr_thread_t * to apr_thread_join().

This + problem in the http_header filter was exposed by the recent rewrite + of the content_length filter. [Taketo Kabe, Bill Stoddard] + + *) Fix seg faults in mod_status with ExtendedStatus enabled, after + restarts. A garbage pointer to a vhost's server_rec from the + previous generation was being left around under certain + conditions. [Greg Ames] + + *) Fix a cosmetic problem with mod_include. Non-existant SSI vars + used to appear as '(none', without the closing paren. + [Günter Knauf <eflash gmx.net>] + + *) Improve the exports generating awk script.

This improvement allows corrects the header file parsing. + [Sander Striker <striker apache.org>] + +Changes with Apache 2.0.21 + + *) Resolve the Win32 htpasswd bug, where a file that existed would be + overwritten, regardless of the -c flag. + [William Rowe, Mladen Turk <mladen.turk mail.inet.hr>] + + *) Introduce connection sub-pools into ab. Truncating the lifetime + of these allocations means that ab no longer perpetually grows + its working set, running out of memory on large request attempts. + [William Rowe] + + *) Make scoreboard creation a hook. This allows management + modules to have access to the scoreboard at the time that it is + created, and at every restart request. + [Cody Sherr <csherr covalent.net>] + + *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and + added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest + daemon index actually used in the scoreboard.

Using the default + httpd.conf, the tables for languages and charsets are somewhat + large, so the time spent scanning them on each request is + significant. Replacing the tables with hash tables provides + a nice speedup. [Brian Pane <bpane pacbell.net>] + + *) Add two functions to allow modules to access random parts of the + scoreboard.

[Ryan Bloom, Bill Stoddard] + +Changes with Apache 2.0.19 + + *) Fix problem with threaded MPM. The problem was that if each child + process was busy serving a single long-lived request and the server + was sent a graceful restart signal, the server would stop serving + requests. This would happen because each child process would wait to + die until the last thread was done, and the parent wouldn't spawn any + new children until a process died. Now, the parent looks at the fact + that the children are dying gracefully, and starts new children. + Those new children only start enough threads to compliment the number + of threads in the other child process that shares the same spot in + the scoreboard. In this way, we make sure to never go over + MaxClients. [Ryan Bloom] + + *) modified mod_negotiation and mod_autoindex to speed up by almost a + factor of two on apr_dir_read()-enhanced platforms, such as Win32 + and OS2, by calling ap_sub_request_lookup_dirent() with the results + already provided by apr_dir_read().

[Greg Stein] + + *) The prefork MPM wasn't killing child processes correctly if a restart + signal was received while the process was serving a request. The child + process would become the equivalent of a second parent process. If + we break out of the accept loop, then we need to do die after cleaning + up after ourselves. [Ryan Bloom] + + *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful + restarts. [Ryan Bloom] + + *) Modify the apr_stat/lstat/getfileinfo calls within apache to use + the most optimal APR_FINFO_wanted bits. This spares Win32 from + performing very expensive owner, group and permission lookups + and allows the server to function until these apr_finfo_t fields + are implemented under Win32. [William Rowe] + + *) Support for typedsafe optional functions - that is functions exported by + optional modules, which, therefore, may or may not be present, depending + on configuration. See the experimental modules mod_optional_fn_{ex,im}port + for sample code. [Ben Laurie] + + *) filters can now report an HTTP error to the server. This is done + by sending a brigade where the first bucket is an error_bucket. + This bucket is a simple bucket that stores an HTTP error and + a string. Currently the string is not used, but it may be needed + to output an error log. The http_header_filter will find this + bucket, and output the error text, and then return + AP_FILTER_ERROR, which informs the server that the error web page + has already been sent. [Ryan Bloom] + + *) If we get an error, then we should remove all filters except for + those critical to serving a web page. This fixes a bug, where + error pages were going through the byterange filter, even though + that made no sense. [Ryan Bloom] + + *) Relax the syntax checking of Host: headers in order to support + iDNS. PR#6635 [Tony Finch] + + *) Cleanup the byterange filter to use the apr_brigade_partition + and apr_bucket_copy functions. This removes a lot of very messy + code, and hopefully makes this filter more stable. + [Ryan Bloom] + + *) Remove AddModule and ClearModuleList directives. Both of these + directives were used to ensure that modules could be enabled + in the correct order. That requirement is now gone, because + we use hooks to ensure that modules are in the correct order. + [Ryan Bloom] + + *) When SuExec is specified, we need to add it to the list of + targets to be built. If we don't, then any changes to the + configuration won't affect SuExec, unless 'make suexec' is + specifically run. [Ryan Bloom] + + *) Cleaned out open_file from mod_file_cache, as apr now accepts + the APR_XTHREAD argument to open a file for consumption by + parallel threads on win32. [William Rowe] + + *) Correct a bug in determining when we follow symlinks. The code + expected a stat -1 result, not an apr_status_t positive error. + Also check if the APR_FINFO_USER fields are valid before we + follow the link. [William Rowe] + + *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to + mpm_common.c. These functions are only valid on some platforms, + so they should not be in the main-line code. [Ryan Bloom] + + *) Remove ap_chdir_file(). This function is not thread-safe, + and nobody is currently using it. [Ryan Bloom] + + *) Do not try to run make depend if there are no .c files in the + current directory, doing so makes `make depend` fail. + [Ryan Bloom] + + *) Update highperformance.conf to work with either prefork or + pthreads mpms. [Greg Ames] + + *) Stop checking to see if this is a pipelined request if we know + for a fact that it isn't. Basically, if r->connection->keepalive == 0. + This keeps us from making an extra read call when serving a 1.0 + request.

[Jeff Trawick] + + *) Some adjustment on the handling and automatic setting (via + hints.m4) of various compilation flags (eg: CFLAGS). Also, + add the capability to specify flags (NOTEST_CFLAGS and + NOTEST_LDFLAGS) which are used to compile Apache, but + not used during the configuration process. Useful for + flags like "-Werror". [Jim Jagielski] + + *) Stop using environment variables to force debug mode or + no detach.

[Ben Laurie] + + *) Stop returning copies of filenames from both apr_file_t and + apr_dir_t.

[Jeff Trawick] + + *) Fix an output truncation error when on an HTTP >= 1.0 request an + object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE + was served through mod_charset_lite (or anything else that would + create a transient bucket in this size range). ap_bucket_make_heap() + silently failed (fixed), transient_setaside() discovered it, but + ap_save_brigade() ignored it (fixed). [Jeff Trawick] + + *) Ignore \r\n or \n when using PEEK mode for input filters. The problem + is that some browsers send extra lines at the end of POST requests, and + we don't want to delay sending data back to the user just because the + browser isn't well behaved. [Ryan Bloom] + + *) Get SuEXEC working again. We can't send absolute paths to suExec + because it refuses to execute those programs. SuEXEC also wasn't + always recognizing configuration changes made using the autoconf + setup. [Ryan Bloom] + + *) Allow the buildconf process to find the config.m4 files in the correct + order. Basically, we can now name config.m4 files as config\d\d.m4, + and we will sort them correctly when inserting them into the build + process. [Ryan Bloom] + + *) Get mod_cgid to use apr calls for creating the actual CGI process. + This also allows mod_cgid to use ap_os_create_priviledged_process, + thus allowing for SuExec execution from mod_cgid. Currently, we do + not support everything that standard SuExec supports, but at least + it works minimally now. [Ryan Bloom] + + *) Allow SuExec to be configured from the ./configure command line. + [Ryan Bloom] + + *) Update some of the docs in README and INSTALL to reflect some of + the changes in Apache 2.0 [Cliff Woolley <cliffwoolley yahoo.com>] + + *) If we get EAGAIN returned from the call to apr_sendfile, then we + need to call sendfile again. This gets us serving large files + such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom] + + *) Get the support programs building cleanly again. + [Cliff Woolley <cliffwoolley yahoo.com>] + + *) The Apache/Win32 Apache.exe and dll's now live in bin. The + current directory logic now backs up over bin/ to determine the + server root from the Apache.exe path. + + *) Apache/Win32 now follows the standard conventions of mod_foo.so + loadable modules, dynamic libs are all named libfoo.dll, and the + makefile.win populates the include, lib and libexec directories. + + *) Apache is now IPv6-capable. On systems where APR supports IPv6, + Apache gets IPv6 listening sockets by default. Additionally, the + Listen, NameVirtualHost, and <VirtualHost> directives support IPv6 + numeric address strings (e.g., "Listen [fe80::1]:8080"). + [Jeff Trawick] + + *) Modify the install directory layout. Modules are now installed in + modules/. Shared libraries should be installed in libraries/, but + we don't have any of those on Unix yet. All install directories + are modifyable at configure time. [Ryan Bloom] + + *) Install all header files in the same directory on Unix. [Ryan Bloom] + + *) Get the functions in server/linked into the server, regardless of + which modules linked into the server. This uses the same hack + for Apache that we use for APR and apr-util to ensure all of the + necessary functions are linked. As a part of thise, the CHARSET_EBCDIC + was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make + the scripts a bit easier. + [Ryan Bloom] + + *) Rework the RFC1413 handling to make it thread-safe, use a timeout + on the query, and remove IPv4 dependencies. [Jeff Trawick] + + *) Get all of the auth modules to the point that they will install and + be loadable into the server. Our new build/install mechanism expects + that all modules will have a common name format. The auth modules + didn't use that format, so we didn't install them properly. + [Ryan Bloom] + + *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer + available. Use apr_getaddrinfo() instead. [Jeff Trawick] + + *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom] + + *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts + after the end of the response. [Ryan Bloom] + + *) Get byterange requests working with responses that do not have a + content-length. Because of the way byterange requests work, we have to + have all of the data before we can actually do the byterange, so we + can compute the content-length in the byterange filter. + [Ryan Bloom] + + *) Get exe CGI's working again on Windows. + [Allan Edwards] + + *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way + they keep track of whether or not their post config hook has been + called before. Instead of a static variable (which is replaced when + the DSO is loaded a second time), use userdata in the process pool. + [Jeff Trawick] + +Changes with Apache 2.0a9 + + *) Win32 now requires perl to complete the final install step for users + to build + install on Win32. Makefile.win now rewrites @@ServerRoot@ + and installs the conf, htdocs and htdocs/manual directories. + [William Rowe] + + *) Make mod_include use a hash table to associate directive tags with + functions. This allows modules to implement their own SSI tags easily. + The idea is simple enough, a module can insert it's own tag and function + combination into a hash table provided by mod_include. While mod_include + parses an SSI file, when it encounters a tag in the file, it does a + hash lookup to find the function that implements that tag, and passes + all of the relevant data to the function. That function is then + responsible for processing the tag and handing the remaining data back + to mod_include for further processing. + [Paul J. Reder <rederpj raleigh.ibm.com>] + + *) Get rid of ap_new_apr_connection(). ap_new_connection() now has + fewer parameters: the local and remote socket addresses were removed + from the parameter list because all required information is available + via the APR socket. [Jeff Trawick] + + *) Distribution directory structure reorganized to reflect a + normal source distribution with external install targets. + [Roy Fielding] + + *) The MPMs that need multiple segments of shared memory now create + two apr_shmem_t variables, one for each shared memory allocation. + the problem is that we can't determine how much memory will be required + for shared memory allocations once we try to allocate more than one + variable. The MM code automatically aligns the shared memory allocations, + so we end up needing to pad the amount of shared memory we want based + on how many variables will be allocated out of the shared memory segment. + It is just easier to create a second apr_shmem_t variable, and two + shmem memory blocks. + [Ryan Bloom] + + *) Cleanup the export list a bit. This creates a single unified list of + functions exported by APR. The export list is generated at configure + time, and that list is then used to generate the exports.c file. + Because of the way the export list is generated, we only export those + functions that are valid on the platform we are building on. + [Ryan Bloom] + + *) Enable logging the cookie with mod_log_config + [Sander van Zoest <sander covalent.net>] + + *) Fix a segfault in mod_info when it reaches the end of the configuration. + [Jeff Trawick] + + *) Added lib/aputil/ as a placeholder for utility functions which are not + specific to the Apache HTTP Server (but do not make sense with APR). + The first utility is "apu_dbm": a set of functions to work with DBM + files. This first version can be compiled for SDBM or GDBM databases. + [Greg Stein] + + *) Complete re-write of mod_include. This makes mod_include a filter that + uses buckets directly. This has now served the FAQ correctly. + [Paul Reder <rederpj raleigh.ibm.com>] + + *) Allow modules to specify the first filter in a sub_request when + making the sub_request. This keeps modules from having to change the + output_filter immediately after creating the sub-request, and therefore + skip the sub_req_output_filter. [Ryan Bloom] + + *) Update ab to accept URLs with IPv6 literal address strings (in the + format described in RFC 2732), and to build Host header fields in + the same format. This allows IPv6 literal address strings to be + used with ab. This support has been tested against Apache 1.3 with + the KAME patch, but Apache 2.0 does not yet work with this format + of the Host header field. [Jeff Trawick] + + *) Accomodate an out-of-space condition in the piped logs and the + rotatelogs.c code, and no longer churn log processes for this + condition. [Victor J.

[David Reid and Jeff Trawick] + + *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but + I have proxied pages with it, cleanup will commence soon. + [Ryan Bloom] + + *) Make the proxy work with filters.

If we can get the C-L correctly, then we + should send it in the HEAD response. + [Ryan Bloom] + + *) The Header filter can now determine if a body should be sent based + on r->header_only. The general idea of this is that if we delay + deciding to send the body, then we might be able to compute the + content-length correctly, which will help caching proxies to cache + our data better. Any handler that doesn't want to try to compute + the content-length can just send an EOS bucket without data and + everything will just work. + [Ryan Bloom] + + *) Add the referer to the error log if one is available. + [Markus Gyger <mgyger itr.ch>] + + *) Mod_info.c has now been ported to Apache 2.0.

This also simplifies + content-length filter a bit, and fixes the actual byte-reporing + code in mod_log_config.c + [Ryan Bloom] + + *) Remove AP_END_OF_BRIGADE definition. This does not signify what + it says, because it was only used by EOS and FLUSH buckets. Since + neither of those are required at the end of a brigade, this was + really signifying FLUSH_THE_DATA, but that can be determined better + by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH + buckets now return a length of 0, which is actually the amount of data + read, so they make more sense. + [Ryan Bloom] + + *) Allow the core_output_filter to save some data past the end of a + request. If we get an EOS bucket, we only send the data if it + makes sense to send it. This allows us to pipeline request + responses. As a part of this, we also need to allocate mmap + buckets out of the connection pool, not the request pool.

Instead of problematic hacks like creating a + dummy.so file (containing dummy references to all global symbols) the + httpd binary is linked against, we use a clean trick stolen from Perl 5: + Placing the Apache core code itself into a DSO library named libhttpd.so. + This way the global symbols _HAVE_ to be exported and thus are available + to any manually loaded DSO's under runtime. To reduce the impact to the + user to null we go even further and create a stub httpd executable which + automatically keeps track of the DSO library loading itself and thus + hides the complete mechanism from the user. Although the generation of + this DSO library is automatically triggered for platforms which + essentially need it (mostly all SVR4-derivates) it can be also enabled + manually via the Rule SHARED_CORE. This can be interesting in the future + where we perhaps exploit this libhttpd.so mechanism for providing nifty + features like graceful upgrades, or whatever. + [Ralf S.

The trick here is that + this approach actually doesn't need the Apache source tree. The + (APACI-installed) server package is enough, because this now includes the + Apache C header files (PREFIX/include) and the new APXS tool + (SBINDIR/apxs). The intend is to provide a handy tool for third-party + module authors to build their Apache modules _OUTSIDE_ the Apache source + tree while avoiding them to fiddle around with the totally platform + dependend way of compiling DSO files. The tool supports all ranges of + modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3 + which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can + on-the-fly generate a minimalistic Makefile and sample module for the + first step to provide both a quick success event and to demonstrate the + APXS mechanism to module authors.

The old names were generally regarded as + too confusing. Also altered "docs" in sample config files. + + *) More improvements to default config files --- + sample directives (commented out) for XBitHack, BindAddress, + CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage + defaults, AddTypes for send-as-is and imagemap magic types, and + improvements to samples for DirectoryIndex [Alexei Kosut] + + *) Yet more improvements to default config files --- changes to + Alexei's sample AddLanguage directives, and sample LanguagePriority + [ Florent Guillaume ] + + *) Set config file locations properly if not set in httpd.conf + [ David Robinson ] + + *) Don't escape URIs in internal redirects multiple times; don't + do that when translating PATH_INFO to PATH_TRANSLATED either. + [ David Robinson ] + + *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson] + +Changes with Apache 0.8.3 + + *) Edited distribution README to *briefly* summarize installation + procedures, and give a pointer to the INSTALL file in the src/ + directory. + + *) Upgraded imagemap script in cgi-bin to 1.8 version from more + recent NCSA distributions. + + *) Bug fix to previous bug fix --- if .htaccess file and <Directory> + exist for the same directory, use both and don't segfault.

[Randy Terbush] + + *) Lightly edited sample config files to refer people to our documentation + instead of NCSA's, and to list Rob McCool as *original* author (also + deleted his old, and no doubt non-functional email address).

[reported by Randy Terbush] + + *) Imagemap module is enabled in default Configuration + + *) RefererLog and UserAgentLog modules properly default the logfile + [Randy Terbush] + + *) Mark Cox's mod_cookies added to the distribution as an optional + module (commented out in the default Configuration, and noted as + an experiment, along with mod_dld). [Mark Cox] + + *) Compiles on ULTRIX (a continuing battle...). [Robert Thau] + + *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush] + + *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau] + + *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD + license] + +Changes with Apache 0.8.1 + + *) New imagemap module [Randy Terbush] + + *) Replacement referer log module with NCSA-compatible RefererIgnore + [Matthew Gray again] + + *) Don't mung directory listings with very long filenames. + [Florent Guillaume] + +Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995 + + *) New config script. See INSTALL for info. [Robert Thau] + + *) Scoreboard mechanism for regulating the number of extant server + processes. MaxServers and StartServers defaults are the same as + for NCSA, but the meanings are slightly different. (Actually, + I should probably lower the MaxServers default to 10). + + Before asking for a new connection, each server process checks + the number of other servers which are also waiting for a + connection. If there are more than MaxServers, it quietly dies + off. Conversely, every second, the root, or caretaker, process + looks to see how many servers are waiting for a new connection; + if there are fewer than StartServers, it starts a new one. This + does not depend on the number of server processes already extant. + The accounting is arranged through a "scoreboard" file, named + /tmp/htstatus.*, on which each process has an independent file + descriptor (they need to seek without interference). + + The end effect is that MaxServers is the maximum number of + servers on an *inactive* server machine, but more will be forked + off to handle unusually heavy loads (or unusually slow clients); + these will die off when they are no longer needed --- without + reverting to the overhead of full forking operation. There is a + hard maximum of 150 server processes compiled in, largely to + avoid forking out of control and dragging the machine down. + (This is arguably too high). + + In my server endurance tests, this mechanism did not appear to + impose any significant overhead, even after I forced it to put the + scoreboard file on a normal filesystem (which might have more + overhead than tmpfs). [Robert Thau] + + *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts. + [Cliff Skolnick] + + *) Read .htaccess files even in directory with <Directory> section. + (Former incompatibility noted on mailing list, now fixed). [Robert + Thau] + + *) "HEAD /" gives the client a "Bad Request" error message, rather + than trying to send no body *and* no headers. [Cliff Skolnick]. + + *) Don't produce double error reports for some very obscure cases + mainly involving auth configuration (the "all modules decline to + handle" case which is a sure sign of a server bug in most cases, + but also happens when authentication is badly misconfigured). + [Robert Thau] + + *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what + it's *for*, and this sort of thing really shouldn't be cluttering + up the Makefile). [Robert Thau] + + *) Incidental code cleanups in http_main.c --- stop dragging + sa_client around; just declare it where used. [Robert Thau] + + *) Another acc-related fix. (It doesn't like const char + in some places...). [Mark Cox] + +Changes with Shambhala 0.6.1 13 Jul 1995 + + *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf] + Also, fixed auth typo in http_protocol.c unmasked by this fix. + + *) Compiles clean with acc on SunOS [Paul Sutton] + + *) Reordered modules in modules.c so that Redirect takes priority + over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] --- + believe it or not, he has an actual site with a ScriptAlias and + a Redirect declared for the *exact same directory*. Even *my* + compatibility fetish wouldn't motivate me to fix this if the fix + required any effort, but it doesn't, so what the hey. + + *) Fixed to properly default several server_rec fields for virtual + servers from the corresponding fields in the main server_rec. + [Cliff Skolnick --- 'port' was a particular irritant]. + + *) No longer kills off nph- child processes before they are + finished sending output. [Matthew Gray] + +Changes with Shambhala 0.6.0 10 Jul 1995 + + *) Two styles of timeout --- hard and soft. soft_timeout()s just put + the connection to the client in an "aborted" state, but otherwise + allow whatever handlers are running to clean up. hard_timeout()s + abort the request in progress completely; anything not tied to some + resource pool cleanup will leak. They're still around because I + haven't yet come up with a more elegant way of handling + timeouts when talking to something that isn't the client. The + default_handler and the dir_handler now use soft timeouts, largely + so I can test the feature. [Robert Thau] + + *) TransferLog "| my_postprocessor ..." seems to be there. Note that + the case of log handlers dying prematurely is probably handled VERY + gracelessly at this point, and if the logger stops reading input, + the server will hang. (It is known to correctly restart the + logging process on server restart; this is (should be!) going through + the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI + script). [Robert Thau] + + *) asis files supported (new module). [Robert Thau] + + *) IdentityCheck code is compiled in, but has not been tested. (I + don't know anyone who runs identd). [Robert Thau] + + *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO + came in with the request, for NCSA bug-compatibility. [Robert Thau] + + *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau] + + *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary, + as timeouts are not in scope. [Robert Thau] + + *) quoted-string args in config files now handled correctly (doesn't drop + the last character). [Robert Thau; reported by Randy Terbush] + + *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX. + How the hell did it ever work? [Robert Thau; reported by Rob Hartill] + + *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time + default default type); the former default default behavior when all + type-checkers defaulted had been a core dump. [Paul Sutton] + + *) Copy filenames out of the struct dirent when indexing + directories. (On Linux, readdir() returns a pointer to the same + memory area every time). Fix is in mod_dir.c. [Paul Sutton] + +Changes with Shambhala 0.5.3 [not released] + + *) Default response handler notes "file not found" in the error log, + if the file was not found. [Cliff Skolnick]. + + *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir + code no longer sets up bogus PATH_INFO which fakes out the directory + handler). [Cliff Skolnick] + +Changes with Shambhala 0.5.2 06 Jul 1995 + + *) Changes to http_main.c --- root server no longer plays silly + games with SIGCHLD, and so now detects and replaces dying + children. Child processes just die on SIGTERM, without taking + the whole process group with them. Potential problem --- if any + child process refuses to die, we hang in restart. + MaxRequestsPerChild may still not work, but it certainly works + better than it did before this! [Robert Thau] + + *) mod_dir.c bug fixes: ReadmeName and HeaderName + work (or work better, at least); over-long description lines + properly terminated. [Mark Cox] + + *) http_request.c now calls unescape_url() more places where it + should [Paul Sutton]. + + *) More directory handling bugs (reported by Cox) + Parent Directory link is now set correctly. [Robert Thau] + +Changes with Shambhala 0.5.1 04 Jul 1995 + + *) Generalized cleanup interface in alloc.c --- any function can be + registered with alloc.c as a cleanup for a resource pool; + tracking of files and file descriptors has been reimplemented in + terms of this interface, so I can give it some sort of a test. + [Robert Thau] + + *) More changes in alloc.c --- new cleanup_for_exec() function, + which tracks down and closes all file descriptors which have been + registered with the alloc.c machinery before the server exec()s a + child process for CGI or <!--#exec-->. CGI children now get + started with exactly three file descriptors open. Hopefully, + this cures the problem Rob H. was having with overly persistent + CGI connections. [Robert Thau] + + *) Mutual exclusion around the accept() in child_main() --- this is + required on at least SGI, Solaris and Linux, and is #ifdef'ed in + by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT). + This uses fcntl(F_SETLK,...) on the error log descriptor because + flock() on that descriptor won't work on systems which have BSD + flock() semantics, including (I think) Linux 1.3 and Solaris. + + This does work on SunOS (when the server is idle, only one + process in the pool is waiting on accept()); it *ought* to work + on the other systems. [Robert Thau] + + *) FreeBSD and BSDI portability tweaks [Chuck Murcko] + + *) sizeof(*sa_client) bugfix from [Rob Hartill] + + *) pstrdup(..., NULL) returns NULL, [Randy Terbush] + + *) block_alarms() to avoid leaking the DBM* in dbm auth (this should + be unnecessary if I go to the revised timeout-handling scheme). + [Robert Thau] + + *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null + string) even if none came in with the request. [Robert Thau] + + *) CHANGES file added to distribution ;-). + +Changes with Shambhala 0.4.5 + + *) mod_dld --- early dynamic loading support [rst] + *) Add wildcard content handlers for XBITHACK; default_hander now + invoked with that mechanism (as a handler hanging off mod_core) [rst] + *) XBITHACK supported as a wildcard content-handler, and + configurable at run-time (not just at compile time, as in the + "patchy server" releases) [rst] + +Changes with Shambhala 0.4.4 30 Jun 1995 + + *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox] + *) Handle Addtype x/y .z [rst, reported by Cox] + +Changes with Shambhala 0.4.3 + + *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not + synonymous [rst, terbush] + +Changes with Shambhala 0.4.1 28 Jun 1995 + + *) First-cut virtual host implementation; some refit in the config + reading code, and log management, was necessary to support this [rst] + *) Sub-pool machinery, originally added to avoid excessive storage + allocation on listings of large directories (which turned out to + be the problem that the 0.3 storage accounting was added to + find). Subrequests and mod_dir changed to use subpools. [rst] + *) More memory debugging --- free list consistency checks. [rst] + *) Added err_headers to request_rec, with support elsewhere [rst] + *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush] + +Changes with Shambhala 0.3 19 Jun 1995 + + *) Switch ONE_PROCESS to a runtime command-line option (-X) + *) Don't compile in mod_ai_backcompat by default + *) Switch name of server from Apache to Shambhala in Makefile + *) Add some accounting routines to track memory usage in the pools, + for debugging + +Changes with Shambhala 0.2 + + *) Set DOCUMENT_ROOT CGI variable + *) Add single-process debugging, as a compile-time option (ONE_PROCESS) + *) Add critical section protection to handling of cleanup structures + in alloc.c [rst] + *) Significant code reorg within the server core to group related + functions together [rst] + *) Correctly handle clients that hang up before sending any request + [rst] + *) Replace dying child processes. [rst] + +Changes with Shambhala 0.1 12 Jun 1995 + + Major rewrite of the pre-existing "patchy server" codebase, by + Robert Thau (rst). Significant portions of the server code, such + as configuration-file handling and HTTP authentication support, + were ripped out and rewritten from scratch. Code that was not + completely rewritten was significantly altered. + + Major changes with this release include: + + *) Introduction of the module API; in request handling, the central + machinery just dispatches to various modules, which actually do + most of the work. Configuration handling is similar --- modules + declare their own commands, and the central machinery just + dispatches to them. + + API features from shambhala/0.1 were substantially unchanged in + Apache 1.0 and 1.1. (1.0 API features not yet present in this + release, such as wildcard handlers and subpools, were added in + subsequent Shambhala releases, and were also generally rst's + work). + + *) This release included the following modules: + + mod_access (access control --- allow and deny directives), + mod_alias (Alias and Redirect commands), + mod_auth (straight HTTP authentication, based on flat-files) + mod_auth_dbm (same, with dbm files) + mod_cgi (CGI scripts and, in this release, ScriptAlias) + mod_common_log (CLF access logs; later renamed mod_log_common) + mod_dir (directory indexing) + mod_include (server-side includes) + mod_mime (AddType directives) + mod_negotiation (content negotiation) + mod_userdir (support for users' public_html directories) + + It also included a mod_ai_backcompat, which was a private hack + for back-compatibility with rst's own AI-lab servers. + + All of these modules were substantially complete, and functional + or nearly so (a few, which implemented features not in use at + Thau's site, required patches of a few lines). + + *) sub-request machinery, to allow modules to determine how other + modules would assign MIME types to a given file, or optionally + serve its content (this is heavily used by mod_dir, mod_include + and mod_negotiation). + + *) Resource pool system for keeping track of memory allocated and + files opened in service of a particular request. Much of the + code in the modules (when they weren't rewrites) was adjusted to + replace a pervasive convention of using fixed-size buffers on + the stack with an equally pervasive convention of using memory + allocated with palloc(). + + *) Reorganization of data structures associated with a given + request to eliminate use of global variables and the troublesome + unmunge_name function (used in NCSA and early Apache releases to + attempt to determine the URI which mapped to a given filename + --- a difficult proposition, given that it is easy to produce + setups in which multiple URIs map to the same file). + + *) Source files renamed and rearranged + + *) Very simple pre-forking behavior --- parent process forked off a + fixed number of children, and then just waited for SIGHUP. + + *) Other more minor changes too numerous to list. + + This release included modified versions of a lot of code from the + Apache 0.6.4 public release, plus an early pre-forking patch + codeveloped by Robert Thau and Rob Hartill. + +Changes with Apache 0.7.3 20 Jun 1995 + + *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that + were incorporated by Rob Hartill on the main branch while Robert Thau + worked on the Shambhala rewrite above. Most were merged into the + Shambala architecture after Apache 0.8.0. + +Changes with Apache 0.6.4 13 May 1995 + + *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau, + and others. + +Changes with Apache 0.5.1 10 Apr 1995 + +Changes with Apache 0.4 02 Apr 1995 + + *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau, + and Rob Hartill. + +Changes with Apache 0.3 24 Mar 1995 + + *) Patches by Robert Thau, David Robinson, Rob Hartill, and + Carlos Varela. + +Changes with Apache 0.2 18 Mar 1995 + + *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT, + Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson, + Brian Behlendorf, Rob Hartill, and Cliff Skolnick. |
