This change adds an optional hook, which allows modules - to gain control while the request is created if the proxy module - is loaded. The purpose of this hook is to allow modules to add - input and/or output filters to the request to the origin. While - I was at it, I made the core use this hook, so that proxy request - creation uses some of the code from the core. This can still be - greatly improved, but this is a good start. [Ryan Bloom] - -Changes with Apache 2.0.26 - - *) Port the MaxClients changes from the worker MPM to the threaded - MPM. [Ryan Bloom] - - *) Fix mod_proxy so that it handles chunked transfer-encoding and works - with the new input filtering system. [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(). [Jeff Trawick] - - *) Use new APR number conversion functions to reduce CPU consumption - when setting the content length, and in mod_log_config. - [Brian Pane] - - *) Fix problem reported by Taketo Kabe <kabe sra-tohoku.co.jp> - where HEAD response headers were being repeated twice for - files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). 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. In the past, we had - work around problems in the awk script by avoiding some #if and - #ifdefs. This has bitten us many times in generating the exports.c - file. 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. I also - updated the pertinent calls. [Paul J. Reder] - - *) Win32: Prevent listening sockets from being inherited by - the Apache child process, CGI scripts, rotatelog process - etc. If the Apache child process segfaults, any processes - that the child started are not reaped. Prior to this fix, - these processes inherited the listening sockets which sometimes - prevented the restarted Apache child process from accepting - connections (ie, the server would hang). - [Bill Stoddard] - - *) Provide vhost and request strings when ExtendedStatus is on. - [Greg Ames] - - *) Fix some issues with the pod and prefork: check the pod *after* - processing a connection so that a server processing a time- - consuming request bails out as soon as practical; when the - parent process wakes up a server process via connect(), use an - APR timeout on the connect() so that we don't hang for a long - time if there aren't server processes around to do accept(). - [Jeff Trawick, Greg Ames] - - *) Performance improvement to mod_mime.c. find_ct() in mod_mime, - spends a lot of time in apr_table_get calls. 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. This allows modules compiled for one MPM to access the - scoreboard, even if it the server was compiled for another MPM. - [Harrie Hazewinkel <harrie covalent.net>] - -Changes with Apache 2.0.20 - - *) Fix problem in content-length filter where the filter would - buffer all the output from a CGI before sending any bytes - down the filter stack to the network. This problem would cause - significant memory consumption if the CGIs generated - lots of bytes. [Bill Stoddard] - - *) Get non-blocking CGI pipe reads working with the bucket brigades. - [Bill Stoddard] - - *) Fix seg fault on Windows when serving files cached with mod_file_cache. - [Bill Stoddard] - - *) Fix a bug in the threaded MPM that would cause it to kill off all - workers immediately after starting if the number of workers started - was above a certain threshold. [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(). [William Rowe] - - *) mod_file_cache is now more robust to filtering and serves requests - slightly more efficiently. [Cliff Woolley] - - *) Fix problem handling FLUSH bucket in the chunked encoding filter. - Module was calling ap_rwrite() followed by ap_rflush() but the - served content was not being displayed in the browser. Inspection - of the output stream revealed that the first data chunk was - missing the trailing CRLF required by the RFC. [Bill Stoddard] - - *) apxs no longer generates ap_send_http_header() in the example handler - - *) Fix an ab problem which could cause a divide-by-zero exception - with certain invocations (e.g., ab -k -c 6 -n 100 localhost/). - [Ian Holsman <ianh cnet.com>] - - *) Solve case-insensitive platforms' confusion about negotiated - filenames, allowing files of differnt case to match in choosing - the document to serve. [William Rowe] - - *) Fix brokenness when ThreadsPerChild is higher than the built-in - limit. We left ap_threads_per_child at the higher value which - led to segfaults when doing certain scoreboard operations. - [Jeff Trawick] - - *) Fix seg faults and/or missing output from mod_include. The - default_handler was using the subrequest pool for files and - MMAPs, even though the associated APR structures typically - live longer than the subrequest. [Greg Ames] - - *) Extend mod_setenvif to support specifying regular expressions - on the SetEnvIf (and SetEnvIfNoCase) directive attribute field. - Example: SetEnvIf ^TS* [a-z].* HAVE_TS - will cause HAVE_TS to be set if any of the request headers begins - with "TS" and has a value that begins with any character in the - set [a-z]. [Bill Stoddard] - - *) httpd children now re-bind themselves to a random CPU on - multiprocessor systems on AIX via bindprocessor() in 2.0. - [Victor J. Orlikowski] - - *) Fix htdigest. It would go into a loop in getline when adding - a second user. [Bill Stoddard] - - *) Win32 platforms now fully support mod_userdir options. [Will Rowe] - - *) Automatically generate httpd.exp for AIX. - DSOs now work again on AIX in 2.0 - [Victor J. Orlikowski] - - *) Add a new request hook, error_log. This phase allows modules - to act on the error log string _after_ it has been written - to the error log. The goal for this hook is to allow monitoring - modules to send the error string to the monitoring agent. - [Ryan Bloom] - - *) Modify mod_echo to make it use filters for input and output. - [Ryan Morgan <rmorgan covalent.net>] - - *) Extend mod_headers to support conditional driven Header - add, append and set. Use SetEnvIf to set an envar and conditionally - add/append/set headers based on this envar thusly: - - SetEnvIf TSMyHeader value HAVE_TSMyHeader - Header add MyHeader "%t %D" env=HAVE_TSMyHeader - - If the request contains header "TSMyHeader: value" then header - MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response. - [Bill Stoddard] - - *) Extend mod_headers to support using format specifiers on Header - add, append and set header values. Two format specifiers are supported: - - %t - reports, in UTC microseconds since the epoch, when the - request was received. - - %D - reports the time, in microseconds, between when the request was - received and the response sent. - - Examples: - Header add MyHeader "This request served in %D microseconds. %t" - - results in a header being added to the response that looks like this: - - MyHeader: This request served in D=5438 microseconds. t=991424704447256 - - [Bill Stoddard] - - *) Fix reset_filter(). We need to be careful how we remove filters. - If we set r->output_filters to NULL, we also have to reset the - connection's filters. [John Sterling] - - *) Optimise reset_filter() in http_protocol.c. [Greg Stein] - - *) Add a check to ap_die() to make sure the filter stack is sane and - contains the correct basic filters when an error occurs. This fixes - a problem where headers are not being sent on error. [John Sterling] - - *) New Header directive 'echo' option. "Header echo regex" will - cause any headers received on the request that match regex to be - echoed to (included in) the response headers. - [Bill Stoddard] - - *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H. - This prevented the inclusion of apr_compat.h. PR #7773 - [Oleg Broytmann <phd phd.pp.ru>] - - *) Moved util_uri to the apr-util library. This required a bunch of - apr_name changes for the uri utility functions. [Justin Erenkrantz] - - *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the - insert_filter phase so that other filters are not bypassed by default. - [Graham Leggett] - - *) Reimplement mod_headers as an output filter. mod_headers can now - add custom headers to inbound requests using the RequestHeader directive - and to responses using the same old Header directive. [Graham Leggett] - -Changes with Apache 2.0.18 - - *) Fix command-line processing so that if a bad argument is specified - Apache will exit. [Jeff Trawick] - - *) Change the make targets and rules to be consistent in all of the - Apache-owned source trees. [Roy Fielding] - - *) Fix processing of the TRACE method. Previously we passed bogus - parms to form_header_field() and it overlaid some vhost structures, - resulting in a segfault in check_hostalias(). - [Greg Ames, Jeff Trawick] - - *) Win32: Add support for reliable piped logs. If the logging process - goes down, Apache will automatically restart it. This function has - been part of Apache on Unix/Linux/BSD since the early v1.3 releases. - [Bill Stoddard] - - *) Do not start piped log processes during the config file - preflight. This change also circumvents a problem on - Windows where the rotatelog processes created during preflight - was not getting cleaned up properly. - [Bill Stoddard] - - *) add "Request Phase Participation" info to mod_info - [Doug MacEachern] - - *) Make first phase changes to the scoreboard data structures in - preparation for the rewriting of the scoreboard per my posted - design notes. [Paul J. Reder] - - *) Fix httpd's definition of LTFLAGS to be consistent with that of apr - and apr-util, allow it to be overridden by the configure command-line - (default="--silent") and introduce LT_LDFLAGS to replace what we were - formerly abusing as LTFLAGS. [Roy Fielding] - - *) Clean up the reporting of incorrect closing container tags. - [Barrie Slaymaker <barries slaysys.com>] - - *) Simplify the configure process by moving all libtool stuff to APR - and moving hints.m4 inline. [Roy Fielding] - - *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types - of functions used by mod_proxy for export in the DLL - [Ian Holsman <IanH cnet.com>] - - *) Prevent a hang when a cgi handled by mod_cgid tries to read a - request body from its stdin but no reqest body is being written to - the cgi. [Jeff Trawick] - - *) mod_log_config: %c connection status incorrectly logged - as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0. - [Bill Stoddard] - - *) Get mod_cern_meta working under Windows - [Bill Stoddard] - - *) Create Files, and thus MMAPs, out of the request pool, not the - connection pool. This solves a small resource leak that had us - not closing files until a connection was closed. In order to do - this, at the end of the core_output_filter, we loop through the - brigade and convert any data we have into a single HEAP bucket - that we know will survive clearing the request_rec. - [Ryan Bloom, Justin Erenkrantz <jerenkrantz ebuilt.com>, - Cliff Woolley] - - *) Completely revamp configure so that it preserves the standard make - variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving - the configure additions to EXTRA_* variables. Also, allow the user - to specify NOTEST_* values for all of the above, which eliminates the - need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting - of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to - avoid pointless duplications. Fix the order in which flags are given - on the compile and link lines. Remove obsolete macros APR_DOEXTRA, - AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE. - Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros. - Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding] - - *) Get mod_tls to compile/work better on Windows. PR #7612 - [Bernhard Schrenk <b.schrenk improx.com>] - - *) Fix shutdown/restart hangs in the threaded MPM. - [Jeff Trawick, Greg Ames, Ryan Bloom] - - *) Removed the keptalive boolean from conn_rec because it is now only - used by a single routine and can be replaced by a local variable. - [Greg Stein, Ryan Bloom, Roy Fielding] - - *) Patch prefork to put enough of the signal processing back in so that - signals are all handled properly now. The previous patch fixed the - deadlock race condition, but broke the user directed signal handling. - This fixes it to work the way it did before my previous prefork patch - (primarily, SIGTERM is now working). - - *) Change how input filters decide how much data is returned to the - higher filter. We used to use a field in the conn_rec, with this - change, we use an argument to ap_get_brigade to determine how much - data is retrieved. [Ryan Bloom] - - *) Fix seg fault at start-up introduced by Ryan's change to enable - modules to specify their own logging tags. mod_log_config - registers an optional function, ap_register_log_handler(). - ap_register_log_handler() was being called by http_core before - the directive hash table was created. This patch creates the - directive hash table before ap_register_log_handler() is - registered as an optional function. - [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>] - - *) Add ap_set_int_slot() function - [John K. Sterling <sterling covalent.net>] - - *) Under certain circumstances, Apache did not supply the - right response headers when requiring authentication. - [Gertjan van Wingerde <Gertjan.van.Wingerde cmg.nl>] PR#7114 - (This is a port of the change that went into Apache 1.3.19.) - - *) Allow modules to specify their own logging tags. This basically - allows a module to tell mod_log_config that when %x is encountered - a specific function should be called. Currently, x can be any single - character. It may be more useful to make this a string at some point. - [Ryan Bloom] - -Changes with Apache 2.0.17 - - *) If a higher-level filter handles the byterange aspects of a - request, then the byterange filter should not try to redo the - work. The most common case of this happening, is a byterange - request going through the proxy, and the origin server handles - the byterange request. The proxy should ignore it. - [Graham Leggett <minfrin sharp.fm>] - - *) Changed the threaded mpm to have child_main join to each of the - worker threads to make sure the kids are all gone before child_main - exits after a signal (cleanup from perform_idle_server_maintenance). - This is an extension of Ryans recent commit to make the child_main - the signal thread. - - *) Add more options to the ap_mpm_query function. This also allows MPMs to - report if their threads are dynamic or static. Finally, this also - implements a new API, ap_show_mpm, which returns the MPM that was - required into the core. [Harrie Hazewinkel <harrie covalent.net>] - - *) Do not install the binaries from the support directory twice. - [jun-ichiro hagino <itojun iijlab.net>] - - *) The ap_f* functions should flush data to the filter that is passed - in, not the filter after the one passed in. - [Ryan Morgan <rmorgan covalent.net>] - - *) Make ab work again by changing its native types to apr types and formats. - [Justin Erenkrantz <jerenkrantz ebuilt.com>] - - *) Move the byterange filter and all of the supporting functions back - to the HTTP module. The byterange filter turned out to be very - HTTP specific, and it belongs in the HTTP module. [Greg Stein] - - *) Make clean, distclean, and extraclean consistently according to the - Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz ebuilt.com>] - - *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions. - This may have been causing problems stopping processes in the threaded - mpm's. [Greg Ames] - - *) Fix content-length in mod_negotiation to a long int representation. - [William Rowe] - - *) Remove BindAddress from the default config file. - [<giles nemeton.com.au>] - - *) Allow module authors to add a module to their Apache build using - --with-module, without re-running buildconf. The syntax is: - --with-module=module_type:/path/to/module.c - The configure script will copy the module.c file to - modules/module_type, and it will be added to the relevant Makefiles. - currently, this only works for static modules. [Ryan Bloom] - - *) Changes required to make prefork clean up idle children properly. - There was a window during which a starting worker deadlocks when - an idle cleanup arrives before it completes init. Apache then keeps - trying to cleanup the same deadlocked worker forever (until higher - pids come along, but it still will never reduce below the deadlocked - pid). Thus the number of children would not reduce to the correct - idle level. [Paul J. Reder] - -Changes with Apache 2.0.16 - - *) Change the default installation directory to /usr/local/apache2, - as now defined by the "Apache" layout in config.layout. [Marc Slemko] - - *) OS/2: Added support for building loadable modules as OS/2 DLLs. - [Brian Havard] - - *) Get MaxRequestsPerChild working with the Windows MPM. - [Bill Stoddard] - - *) Make generic hooks to work, with mod_generic_hook_import/export - experimental modules. [Ben Laurie, Will Rowe] - - *) Fix segfaults for configuration file syntax errors such as - "<Directory>" followed by "</Directory" and - "<Directory>" followed by "</Directoryz>". [Jeff Trawick] - - *) Cleanup the --enable-layout option of configure. This makes - us use a consistent location for the config.layout file, and it - makes configure more portable. - [jun-ichiro hagino <itojun iijlab.net>] - - *) Changes to 'ab'; fixed int overrun's, added statistics, output in - csv/gnuplot format, rudimentary ssl support and various other tweaks - to make results more true to what is measured. The upshot of this it - turns out that 'ab' has often underreported the true performance of - apache. Often by a order of magnitude :-) See talk/paper of Sander - Temme at April ApacheCon 2001 for details. - [Dirk-Willem van Gulik] - - *) Clean up mod_cgid's temporary request pool. Besides fixing a - storage leak this ensures that some unnecessary pipes are closed. - [Jeff Trawick] - - *) Performance: Add quick_handler hook. This hook is called at the - very beginning of the request processing before location_walk, - translate_name, etc. This hook is useful for URI keyed content - caches like Mike Abbott's Quick Shortcut Cache. - [Bill Stoddard] - - *) top_module global variable renamed to ap_top_module [Perl] - - *) Move ap_set_last_modified to the core. This is a potentially - controversial change, because this is kind of HTTP specific. However - many protocols should be able to take advantage of this kind of - information. I expect that headers will need one more layer of - indirection for multi-protocol work, but this is a small step in - the right direction. [Ryan Bloom] - - *) Enable mod_status by default. This matches what Apache 1.3 does. - [Ed Korthof] - - *) Add a ScriptSock directive to the default config file. This is - only enabled when mod_cgid is used. - [Taketo Kabe <kabe sra-tohoku.co.jp>] - -Changes with Apache 2.0.15 - - *) Untangled the buildconf script and eliminated the need for build's - aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other - libtool muck that is now under srclib/apr/build. [Roy Fielding] - - *) Win32: Don't accept more connections than we have worker threads - to handle. - [Bill Stoddard] - - *) Fix bug in the Unix threaded.c MPM that allowed child processes - to fork() new child processes. - [Bill Stoddard] - - *) SECURITY: Fix a major security problem with double-reverse lookup - checking. Previously, a client connecting over IPv4 would not be - matched properly when the server had an IPv6 listening socket. - PR #7407 [Taketo Kabe <kiabe sra-tohoku.co.jp>] - - *) Change the way the beos MPM handles polling to allow it to stop and - restart. Problem was the sockets being polled were being reset by - the select call, so once it had accepted a connection it was no - longer listening on the UDP socket we use for shutdown instructions. - APR needs to be altered, patch on it's way. [David Reid] - - *) Empty out the brigade shared by ap_getline()/ap_get_client_block() - on error exit from ap_getline(). Some other code got upset because - the wrong data was in the brigade. [Greg Ames, Jeff Trawick] - - *) Handle ap_discard_request_body() being called more than once. - [Greg Ames, Jeff Trawick] - - *) Get rid of an inadvertent close of file descriptor 2 in - mod_mime_magic. [Greg Ames, Jeff Trawick] - - *) Add a hook, create_request. This hook allows modules to modify - a request while it is being created. This hook is called for all - request_rec's, main request, sub request, and internal redirect. - When this hook is called, the r->main, r->prev, r->next - pointers have been set, so modules can determine what kind of - request this is. [Ryan Bloom] - - *) Cleanup the build process a bit more. The Apache configure - script no longer creates its own helper scripts, it just - uses APR's. - [jean-frederic clere <jfrederic.clere fujitsu-siemens.com>] - - *) Stop the forced downgrade of the connection to HTTP/1.0 for - proxy requests. [Graham Leggett] - - *) Avoid using sscanf to determine the HTTP protocol number in - the common case because sscanf is a performance hog. From - Mike Abbot's Accelerating Apache patch number 6. - [Mike Abbot <mja trudge.engr.sgi.com>, Bill Stoddard] - - *) SECURITY: Fix a security exposure in mod_access. Previously when - IPv6 listening sockets were used, allow/deny-from-IPv4-address rules - were not evaluated properly (PR #7407). Also, add the ability to - specify IPv6 address strings with optional prefix length on Allow - and Deny. [Jeff Trawick] - - *) Enhance rotatelogs so that a UTC offset can be specified, and - the logfile name can be formatted using strftime(3). (Brought - forward from 1.3.) [Ken Coar] - - *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling - DuplicateHandle on an IOCompletionPort (a practice which - MS "discourages"). The new model does not rely on associating - the completion port with the listening sockets, thus the - completion port can be completely managed within the child - process. A dedicated thread accepts connections off the network, - then calls PostQueuedCompletionStatus() to wake up worker - threads blocked on the completion port. - [Bill Stoddard] - - *) Bring forward the --suexec-umask option which allows the - builder to preset the umask for suexec processes. [Ken Coar] - - *) Add a -V flag to suexec, which causes it to display the - compile-time settings with which it was built. (Only - usable by root or the AP_HTTPD_USER username.) [Ken Coar] - - *) Mod_include should always unset the content-length if the file is - going to be passed through send_parsed_content. There is no to - determine if the content will change before actually scanning the - entire content. It is far safer to just remove the C-L as long - as we are scanning it. [Ryan Bloom] - - *) Make sure Apache sends WWW-Authenticate during a reverse proxy - request and not Proxy-Authenticate. - [Graham Leggett <minfrin sharp.fm>] - -Changes with Apache 2.0.14 - - *) Fix content-length computation. We ONLY compute a content-length if - We are not in a 1.1 request and we cannot chunk, and this is a keepalive - or we already have all the data. [Ryan Bloom] - - *) Report unbounded containers in the config file. Previously, a typo - in the </container> directive could result in the rest of the config - file being silently ignored, with undesired defaults used. - [Jeff Trawick] - - *) Make the old_write filter use the ap_f* functions for the buffering. - [Ryan Bloom] - - *) Move more code from the http module into the core server. This - is core code, basically the default handler, the default input - and output filters, and all of the core configuration directives. - All of this code is required in order for the server to work, with or - without HTTP. The server is closer to working without the HTTP - module, although there is still more to do. [Ryan Bloom] - - *) Fix a number of SGI compile warnings throughout the server. Fix some - bad parameters to apr_bucket_read(). Fix a bad statement in - ap_method_in_list(). For the mod_rewrite cache use apr_time_t - consistently; we were mixing apr_time_t and time_t in invalid ways - before. In load_file(), call apr_dso_error() instead of - apr_strerror() so that we get a more specific string on some platforms. - PR #6980 [Jeff Trawick] - - *) Allow modules to query the MPM about it's execution profile. This - query API can and should be extended in the future, but for now, - max_daemons, and threading or forking is a very good start. - [Jon Travis <jtravis covalent.net>] - - *) Modify mod_include to send blocks of data no larger than 9k. - Without this, mod_include will wait until the whole file is parsed, - or the first tag is found to send any data to the client. - [Paul J.

The goal - is to have only functions that are HTTP specific in the http directory. - [Ryan Bloom] - -Changes with Apache 2.0.13 - - *) Don't assume that there will always be multiple calls to the byterange - filter. It is possible that we will need to do byteranges with only - one call to the filter. [Ryan Morgan <rmorgan covalent.net>] - - *) Move the error_bucket definition from the http module to the - core server. Every protocol will need this ability, not just - HTTP. [Ryan Bloom] - -Changes with Apache 2.0.12 - - *) Modify mod_file_cache to save pre-formatted strings for - content-length and last-modified headers for performance. - [Mike Abbot <mja trudge.engr.sgi.com>] - - *) Namespace protect IOBUFSIZ since it is exposed in the API. - [Jon Travis <jtravis covalent.net>] - - *) Use "Basic" authentication instead of "basic" in ab, as the spec - says we should. [Andre Breiler <andre.breiler rd.bbc.co.uk>] - - *) Fix a seg fault in mod_userdir.c. We used to use the pw structure - without ever filling it out.

[Clive Lin <clive CirX.ORG>] PR#7142 - - *) Migrate the perchild MPM to use the new apr signal child, and - APR thread functions. [Ryan Bloom] - - *) Close one copy of the CGI's stdout before creating the new process. - The CGI will still have stdout, because we have already dup'ed it. - This keeps Apache from waiting forever to send the results of a CGI - process that has forked a long-lived child process. - [Taketo Kabe <kabe sra-tohoku.co.jp>] - - *) Remove the rest of the pthreads functions from the threaded MPM. - This requires the APR support for a signal thread that was just - added. [Ryan Bloom] - - *) Make mod_dir use a fixup for sending a redirect to the browser. - Before this, we were using a handler, which doesn't make much - sense, because the handler wasn't generating any data, it would - either return a redirect error code, or DECLINED. This fits the - current hooks better. [Ryan Morgan <rmorgan covalent.net>] - - *) Make the threaded MPM use APR threads instead of pthreads. - [Ryan Bloom] - - *) Get mod_tls to the point where it actually appears to work in all cases. - [Ben Laurie] - - *) implement --enable-modules and --enable-mods-shared for "all" and - "most". [Greg Stein] - - *) Move the threaded MPM to use APR locks instead of pthread locks. - [Ryan Bloom] - - *) Rename mpmt_pthread to threaded. This is more in line with the - fact that mpmt_pthread shouldn't be using pthreads directly, and - it is a smaller name that doesn't tie into anything. - [Ryan Bloom] - - *) Rename the module structures so that the exported symbol matches - the file name, and it is easier to automate the installation - process (generating LoadModule directives from the module filenames). - [Martin Kraemer] - - *) Remove the coalesce filter. With the ap_f* functions, this filter - is no longer needed. [Ryan Bloom] - -Changes with Apache 2.0.11 - - *) Remove the dexter MPM. Perchild is the same basic idea, but it has the - added feature of allowing a uid/gid per child process. If no - uid/gid is specified, then Perchild behaves exactly like dexter. - [Ryan Bloom] - - *) Get perchild building again. [Ryan Bloom] - - *) Don't disable threads just because we are using the prefork MPM. - If somebody wants to compile without threads, they must now add - --disable-threads to the configure command line. [Ryan Bloom] - - *) Begin to move the calls to update_child_status into common code, so - that each individual MPM does not need to update the scoreboard itself. - [Ryan Bloom] - - *) Allow mod_tls to compile under Unix boxes where openssl has been - installed to the system include files. - [Gomez Henri <new-httpd slib.fr>] - - *) Cleanup the mod_tls configure process. This should remove any need - to hand-edit any files. We require OpenSSL 0.9.6 or later, but - configure doesn't check that yet. [Ryan Bloom] - - *) Add a very early prototype of SSL support (in mod_tls.c). It is - vital that you read modules/tls/README before attempting to build - it. [Ben Laurie] - - *) Fix a potential seg fault on all platforms. David Reid fixed this - on BEOS, but the problem could happen anywhere, so we don't want - to #ifdef it. [Cliff Woolley <cliffwoolley yahoo.com>] - - *) Add new LogFormat directive, %D, to log time it takes to serve a - request in microseconds. [Bill Stoddard] - - *) Change AddInputFilter and AddOutputFilter to SetInputFilter and - SetOutputFilter. This corresponds nicely with the other Set - directives, which operate on containers while the Add* directives - tend to work directly on extensions. [Ryan Bloom] - - *) Cleanup the header handling a bit. This uses the apr_brigade_* - functions for the buffering so that we don't need to compute - the length of the headers before we actually create the header - buffer. [Ryan Bloom] - - *) Allow filters to buffer data using the ap_f* functions. These have - become macros that resolve directly to apr_brigade_*. - [Ryan Bloom] - - *) Get the Unix MPM's to do a graceful restart again. If we are going - to register a cleanup with ap_cleanup_scoreboard, then we have to - kill the cleanup with the same function, and that function can't be - static. [Ryan Bloom] - - *) Install all required header files. Without these, it was not - possible to compile some modules outside of the server. - [Ryan Bloom] - - *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch - forward from 1.3 to 2.0, we missed a single line, which broke regex - aliases. [Ryan Bloom] - - *) We have a poor abstraction in the protocol. This is a temporary - hack to fix the bug, but it will need to be fixed for real. If - we find an error while sending out a custom error response, we back - up to the first non-OK request and send the data. Then, when we send - the EOS from finalize_request_protocol, we go to the last request, - to ensure that we aren't sending an EOS to a request that has already - received one. Because the data is sent on a different request than - the EOS, the error text never gets sent down the filter stack. This - fixes the problem by finding the last request, and sending the data - with that request. [Ryan Bloom] - - *) Make the server status page show the correct restart time, and - thus the proper uptime. [Ryan Bloom] - - *) Move the CGI creation logic from mod_include to mod_cgi(d). This - should reduce the amount of duplicate code that is required to - create CGI processes. - [Paul J. Reder <rederpj raleigh.ibm.com>] - - *) ap_new_connection() closes the socket and returns NULL if a socket - call fails. Usually this is due to a connection which has been - reset.

This is needed because configure - options do not support multiple flags separated by spaces. - [Roy Fielding] - - *) Fix some byterange handling. If we get a byte range that looks like - "-999999" where that is past the end of the file, we should return - a PARTIAL CONTENT status code, and return the whole file as one big - byterange. This matches the 1.3 handling now. [Ryan Bloom] - - *) Make the error bucket a real meta-data bucket. This means that the - bucket length is 0, and a read returns NULL data. If one of these - buckets is passed down after the headers are sent, this data will - just be ignored. [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. [Ryan Bloom and Greg Stein] - - *) Fix the handling of variable expansion look-ahead in mod_rewrite, - i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of - more complicated nested RewriteMap lookups. PR#7087 [Tony Finch] - - *) Fix the RFC number mentioned when complaining about a missing - Host: header. PR#7079 [Alexey Toptygin <alexeyt wam.umd.edu>] - - *) Fix an endless loop in ab which occurred when ab was posting - and the server dropped the connection unexpectedly. - [Jeff Trawick] - - *) Fix a segfault while handling request bodies in ap_http_filter(). - This problem has been seen with mod_dav usage as well as with - requests where the body was just being discarded. [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. We now use the -D command line argument to - specify the correct mode. -DONE_PROCESS and -DNO_DETACH. - [Greg Stein, Ryan Bloom] - - *) Change handlers to use hooks. [Ben Laurie] - - *) Stop returning copies of filenames from both apr_file_t and - apr_dir_t. We pstrdup the filenames that we store in the - actual structures, so we don't need to pstrdup the strings again. - [Ryan Bloom] - - *) mod_cgi: Fix some problems where the wrong error value was being - traced. [Jeff Trawick] - - *) EBCDIC: Fix some missing ASCII conversion on some protocol data. - [Jeff Trawick] - - *) Add generic hooks. [Ben Laurie] - - *) Use a real pool to dup the error log descriptor. [Ryan Bloom] - - *) Fix a segfault caused by mod_ext_filter when the external filter - program does not exist. [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. Orlikowski] - - *) Add support for partial writes with apr_sendfile() to core_output_filter. - [Greg Ames] - -Changes with Apache 2.0a8 - - *) Add a directive to mod_mime so that filters can be associated with - a given mime-type. - [Ryan Bloom] - - *) Get multi-views working again. We were setting the path_info - field incorrectly if we couldn't find the specified file. - [Ryan Bloom] - - *) Fix 304 processing. The core should never try to send the headers - down the filter stack. Always, just setup the table in the request - record, and let the header filter convert it to data that is ready - for the network. - [Ryan Bloom] - - *) More fixes for the proxy. There are still bugs in the proxy code, - but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP) - successfully. - [Ryan Bloom] - - *) Fix params for apr_getaddrinfo() call in connect proxy handler. - [Chuck Murcko] - - *) APR: Add new apr_getopt_long function to handle long options. - [B. W. Fitzpatrick <fitz red-bean.com>] - - *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname. - Add generic apr_create_socket(). Add apr_getaddrinfo() for doing - hostname resolution/address string parsing and building - apr_sockaddr_t. Add apr_get_sockaddr() for getting the address - of one of the apr_sockaddr_t structures for a socket. Change - apr_bind() to take apr_sockaddr_t. [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. This isn't perfect, because we - aren't dealing with the headers properly. [Ryan Bloom] - - *) Do not send a content-length iff the C-L is 0 and this is a head - request. [Ryan Bloom] - - *) Make cgi-bin work as a regular directory when using mod_vhost_alias - with no VirtualScriptAlias directives. PR#6829 [Tony Finch] - - *) Remove BUFF from the PROXY connect handling. [Ryan Bloom] - - *) Get the default_handler to stop trying to deal with HEAD requests. - The idea is to let the content-length filter compute the C-L before - we try to send the data. 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. As a part of this - change, the root of the configuration tree has been exposed to modules - as ap_conftree. - [Ryan Morgan <rmorgan covalent.net>] - - *) Get the core_output_filter to use the bucket interface directly. - This keeps us from calling the content-length filter multiple times - for a simple static request. - [Ryan Bloom] - - *) We are sending the content-type correctly now. - [Ryan Bloom and Will Rowe] - - *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report - a bogus bytes-sent value when the only thing being sent was trailers - and writev() returned an error (or EAGAIN). [Jeff Trawick] - - *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the - hints file to determine which platforms define - SINGLE_LISTEN_UNSERIALIZED_ACCEPT. - [Ryan Bloom] - - *) APR: add apr_get_home_directory() [Jeff Trawick] - - *) Initial import of 1.3-current mod_proxy. [Chuck Murcko] - - *) Not all platforms have INADDR_NONE defined by default. Apache - used to make this check and define INADDR_NONE if appropriate, - but APR needs the check too, and I suspect other applications will - as well. APR now defines APR_INADDR_NONE, which is always a valid - value on all platforms. - [Branko Čibej <brane xbc.nu>] - - *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824. - [Shuichi Kitaguchi <ki hh.iij4u.or.jp>] - - *) Relax the syntax checking of Host: headers in order to support - iDNS. PR#6635 [Tony Finch] - - *) When reading from file buckets we convert to an MMAP if it makes - sense. This also simplifies the default handler because the - default handler no longer needs to try to create MMAPs. - [Ryan Bloom] - - *) BUFF has been removed from the main server. The BUFF code will remain - in the code until it has been purged from the proxy module as well. - [Ryan Bloom] - - *) Byteranges have been completely re-written to be a filter. This - has been tested, and I believe it is working correctly, but it could - doesn't work for the Adobe Acrobat plug-in. The output almost matches - the output from 1.3, the only difference being that 1.3 includes - a content-length in the response, and this does not. - [Ryan Bloom] - - *) APR read/write functions and bucket read functions now operate - on unsigned integers, instead of signed ones. It doesn't make - any sense to use signed ints, because we return the error codes, - so if we have an error we should report 0 bytes read or written. - [Ryan Bloom] - - *) Always compute the content length, whether it is sent or not. - The reason for this, is that it allows us to correctly report - the bytes_sent when logging the request. 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. This - allows the mmap to outlive the request. - [Ryan Bloom] - - *) Make blocking and non-blocking bucket reads work correctly for - sockets and pipes. These are the only bucket types that should - have non-blocking reads, because the other bucket types should - ALWAYS be able to return something immediately. - [Ryan Bloom] - - *) In the Apache/Win32 console window, accept Ctrl+C to stop the - server, but use Ctrl+Break to initiate a graceful restart - instead of duplicating behavior. [John Sterling] - - *) Patch mod_autoindex to set the Last-Modified header based on - the directory's mtime, and add the ETag header. [William Rowe] - - *) Merge the 1.3 patch to add support for logging query string in - such a way that "%m %U%q %H" is the same as "%r". - [Bill Stoddard] - - *) Port three log methods from mod_log_config 1.3 to 2.0: - CLF compliant '-' byte count, method and protocol. - [Bill Stoddard] - - *) Add a new LogFormat directive, %c, that will log connection - status at the end of the response as follows: - 'X' - connection aborted before the response completed. - '+' - connection may be kept-alive by the server. - '-' - connection will be closed by the server. - [Bill Stoddard] - - *) Expand APR for WinNT to fully accept and return utf-8 encoded - Unicode file names and paths for Win32, and tag the Content-Type - from mod_autoindex to reflect that charset if the feature - macro APR_HAS_UNICODE_FS is true. [William Rowe] - - *) Compute the content length (and add appropriate header field) for - the response when no content length is available and we can't use - chunked encoding. [Jeff Trawick] - - *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK, - so that content input filters get dechunked data when using - the default handler. Also removed REQUEST_CHUNKED_PASS. - [Sascha Schumann] - - *) Add mod_ext_filter as an experimental module. This module allows - the administrator to use external programs as filters. Currently, - only filtering of output is supported. [Jeff Trawick] - - *) Most Apache functions work on EBCDIC machines again, as protocol - data is now translated (again). [Jeff Trawick] - - *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of - the EBCDIC support. They are noops on ASCII machines, so this - type of translation doesn't have to be surrounded by #ifdef - CHARSET_EBCDIC. [Jeff Trawick] - - *) Fix mod_include. tag commands work again, and the server will - send the FAQ again. This also allows mod_include to set aside - buckets that include partial buckets. - [Ryan Bloom and David Reid] - - *) Add suexec support back. [Manoj Kasichainula] - - *) Lingering close now uses the socket directly instead of using - BUFF. This has been tested, but since all we can tell is that it - doesn't fail, this needs to be really hacked on. - [Ryan Bloom] - - *) Allow filters to modify headers and have those headers be sent to - the client. The idea is that we have an http_header filter that - actually sends the headers to the network. This removes the need - for the BUFF to send headers. - [Ryan Bloom] - - *) Charset translation: mod_charset_lite handles translation of - request bodies. Get rid of the xlate version of ap_md5_digest() - since we don't compute digests of filtered (e.g., translated) - response bodies this way anymore. (Note that we don't do it at - all at the present; somebody needs to write a filter to do so.) - [Jeff Trawick] - - *) Input filters and ap_get_brigade() now have a input mode parameter - (blocking, non-blocking, peek) instead of a length parameter. - [hackathon] - - *) Update the mime.types file to the registered media types as - of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp home.net>, - Tony Finch] - - *) Namespace protect some macros declared in ap_config.h - [Ryan Bloom] - - *) Support HTTP header line folding with input filtering. - [Greg Ames] - - *) Mod_include works again. This should still be re-written, but at - least now we can serve an SHTML page again. - [Ryan Bloom] - - *) Begin to remove BUFF from the core. Currently, we keep a pointer - to both the BUFF and the socket in the conn_rec. Functions that - want to use the BUFF can, functions that want to use the socket, - can. They point to the same place. - [Ryan Bloom] - - *) apr_psprintf doesn't understand %lld as a format. Make it %ld. - [Tomas Ögren <stric ing.umu.se>] - - *) APR pipes on Unix and Win32 are now cleaned up automatically when the - associated pool goes away. (APR pipes on OS/2 were already had this - logic.) This resolvs a fatal file descriptor leak with CGIs. - [Jeff Trawick] - - *) The final line of the config file was not being read if there was - no \n at the end of it. This was caused by apr_fgets returning - APR_EOF even though we had read valid data. This is solved by - making cfg_getline check the buff that was returned from apr_fgets. - If apr_fgets return APR_EOF, but there was data in the buf, then we - return the buf, otherwise we return NULL. - [Ryan Bloom] - - *) Piped logs work again in the 2.0 series. - [Ryan Bloom] - - *) Restore functionality broken by the mod_rewrite security fix: - rewrite map lookup keys and default values are now expanded - so that the lookup can depend on the requested URI etc. - PR #6671 [Tony Finch] - - *) SECURITY: Tighten up the syntax checking of Host: headers to fix a - security bug in some mass virtual hosting configurations - that can allow a remote attacker to retrieve some files - on the system that should be inaccessible. [Tony Finch] - - *) Add a pool bucket type. This bucket is used for data allocated out - of a pool. If the pool is cleaned before the bucket is destroyed, then - the data is converted to a heap bucket, allowing it to survive the - death of the pool. - [Ryan Bloom] - - *) Add a flush bucket. This allows modules to signal that the filters - should all flush whatever data they currently have. There is no way - to actually force them to do this, so if a filter ignores this bucket, - that's life, but at least we can try with this. - [Ryan Bloom] - - *) Add an output filter for sub-requests. This filter just strips the - EOS bucket so that we don't confuse the main request's core output - filter by sending multiple EOS buckets. This change also makes sub - requests start to send EOS buckets when they are finished. - [Ryan Bloom] - - *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also - makes ap_bucket_destroy a return void, which is okay because it - used to always return APR_SUCCESS, and nobody ever checked its - return value anyway. - [Cliff Woolley <cliffwoolley yahoo.com>] - - *) Remove the index into the bucket-type table from the buckets - structure. This has now been replaced with a pointer to the - bucket_type. Also add some macros to test the bucket-type. - [Ryan Bloom] - - *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols - for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper) - and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE. - All _VAR_ flavors changes to _DATA to be absolutely clear. - [William Rowe] - - *) Add support for /, //, //servername and //server/sharename - parsing of <Directory> blocks under Win32 and OS2. - [Tim Costello, William Rowe, Brian Harvard] - - *) Remove the function pointers from the ap_bucket type. They have been - replaced with a global table. Modules are allowed to register bucket - types and use then use those buckets. - [Ryan Bloom] - - *) mod_cgid: In the handler, shut down the Unix socket (only for write) - once we finish writing the request body to the cgi child process; - otherwise, the client doesn't hit EOF on stdin. Small request bodies - worked without this change (for reasons I don't understand), but large - ones didn't. [Jeff Trawick] - - *) Remove file bucket specific information from the ap_bucket type. - This has been moved to a file_bucket specific type that hangs off - the data pointer in the ap_bucket type. - [Ryan Bloom] - - *) Input filtering now has a third argument. This is the amount of data - to read from lower filters. This argument can be -1, 0, or a positive - number. -1 means give me all the data you have, I'll deal with it and - let you know if I need more. 0 means give me one line and one line - only. A positive number means I want no more than this much data. - - Currently, only 0 and a positive number are implemented. This allows - us to remove the remaining field from the conn_rec structure, which - has also been done. - [Ryan Bloom] - - *) Big cleanup of the input filtering. The goal is that http_filter - understands two conditions, headers and body. It knows where it is - based on c->remaining. If c->remaining is 0, then we are in headers, - and http_filter returns a line at a time. If it is not 0, then we are - in body, and http_filter returns raw data, but only up to c->remaining - bytes. It can return less, but never more. - [Greg Ames, Ryan Bloom, Jeff Trawick] - - *) mod_cgi: Write all of the request body to the child, not just what - the kernel would accept on the first write. [Jeff Trawick] - - *) Back out the change that moved the brigade from the core_output_filters - ctx to the conn_rec. Since all requests over a given connection - go through the same core_output_filter, the ctx pointer has the - correct lifetime. - [Ryan Bloom] - - *) Fix another bug in the send_the_file() read/write loop. A partial - send by apr_send would cause unsent data in the read buffer to - get clobbered. Complete making send_the_file handle partial - writes to the network. - [Bill Stoddard] - - *) Fix a couple of type fixes to allow compilation on AIX again - [Victor J. Orlikowski <v.j.orlikowski gte.net>] - - *) Fix bug in send_the_file() which causes offset to be ignored - if there are no headers to send. - [Bill Stoddard] - - *) Handle APR_ENOTIMPL returned from apr_sendfile in the core - filter. Useful for supporting Windows 9* with a binary - compiled on Windows NT. - [Bill Stoddard] - -Changes with Apache 2.0a7 - - *) Reimplement core_output_filter to buffer/save bucket brigades - across multiple calls to the core_filter. The brigade will be - sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE - thresholds are hit or the EOS bucket is received. - [Bill Stoddard] - - *) Create experimental filter (buffer_filter) that coalesces bytes - into one large buffer before invoking the next filter in the - chain. This filter is particularly useful with the current - implementation of mod_autoindex when it inserted above the - chunk_filter. mod_autoindex generates a lot of brigades that - containing buckets holding just a few bytes each. The - buffer_filter coalesces these buckets into a single large bucket. - [Bill Stoddard] - - *) Add apr_sendfile() support into the core_output_filter. - [Bill Stoddard] - - *) Add apr_sendv() support into the core_output_filter. - [Bill Stoddard] - - *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS - [Mike Abbott <mja sgi.com>] - - *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't - make much sense, because Apache uses buckets instead of BUFFs now. - [Ryan Bloom] - - *) send_the_file now falls back to a read/write loop on platforms that - do not have sendfile. - [Ryan Bloom and Brian Havard] - - *) Install apachectl correctly, and substitute the proper values so - that it works again. [Ryan Bloom] - - *) Better(??) handle platforms that lack sendfile(). - [Jim Jagielski] - - *) APR now has UUID generation/formatting/parsing support. - [Greg Stein] - - *) Begin the http_filter. This is an input filter that understands - the absolute basic amount required to parse an HTTP Request. The - goal is to be able to split headers from request body before passing - the data back to the other filters. - [Ryan Bloom] - - *) Bring forward from 1.3.13 the config directory implementation - [Jim Jagielski] - - *) install apxs if it is created - [Ryan Bloom] - - *) Added APR_IS_STATUS_condition test macros to eliminate canonical error - conversions. [William Rowe] - - *) Now that we have ap_add_input_filter(), rename ap_add_filter() to - ap_add_output_filter(). [Jeff Trawick] - - *) Multiple build and configuration fixes - Build process: - - -add datadir and localstatedir substitutions - -fix layout name - -fix logfilename misspelling - -fix evaluation of installation dir variables and - -replace $foobar by $(foobar) to be usefull in the makefile - - Cross compile: - - -add rules for cross-compiling in rules.mk. Okay, rule to check for - $CC_FOR_BUILD is still missing - -use CHECK_TOOL instead of CHECK_PROG for ranlib - -add missing "AR=@AR@" to severaly Makefile.in's - -cache result for "struct rlimit" - -compile all helper programs with native and cross compiler - and use the native version to generate header file - [Rüdiger Kuhlmann <Tadu gmx.de>] - - *) Prepare our autoconf setup for autoconf 2.14a and for cross- - compiling. - [Rüdiger Kuhlmann <Tadu gmx.de>] - - *) Fix a bug where a client which only sends \n to delimit header - lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED - message. Start working on ebcdic co-existance with input - filtering. - [William Rowe, Greg Ames] - - *) If mod_so is enabled in the server always create libexec, even - if there are no modules installed in this directory. This is a - requirement for APXS to work correctly. - [Ryan Bloom] - - *) Connection oriented output filters are now stored in the - conn_rec instead of the request_rec. This allows us to add the - output filter in the pre-connection phase instead of the - post_read_request phase, which keeps us from trying to write an - error page before we have a filter to write to the network. - [Ryan Bloom, Jeff Trawick, and Greg Ames] - - *) Cleaning up an mmap bucket no longer deletes the mmap. An - mmap can be used across multiple buckets (default_handler with - byte ranges, mod_file_cache, mod_mmap_static), so cleanup of - the mmap itself can't be associated with the bucket. - [Jeff Trawick] - - *) Add .dll caching directive ISAPICacheFile to mod_isapi. - [William Rowe] - - *) Radical surgery to improve mod_isapi support under Win32. - Includes a number of newer ServerSupportFunction calls, support - for ReadClient (in order to retrieve POSTs greater than 48KB), - and general bug fixes to more reliably load ISAPI .dll's and - prevent leaking handle resources. Note: There are still - discrepancies between IIS's and Apache's ServerVariables, and - async calls are still not supported. Additional warnings are - logged to facilitate debugging of unsupported ISAPI calls. - [William Rowe] - - *) Add input filtering to Apache. The basic idea for the input - filters is the same as the ideas for output filters. The biggest - difference is that instead of calling ap_pass_brigade, ap_get_brigade - should be called, and the order of execution for the filter itself is - different. When writing an output filter, a brigade is passed in, - and filters operate directly on that brigade, when done, they call - ap_pass_brigade. Input filters are the exact opposite. Because input - is not a push operation, filters first call ap_get_brigade. When this - function returns, the input filter will be left with a valid brigade. - The input filter should then operate on the brigade, and return. - [Ryan Bloom] - - *) Fix building on BSD/OS using its native make. The build system - falls back to the BSD .include directive on that host platform. - [Sascha Schumann] - - *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5, - SHA1 and plaintext password encodings. Make feature tests a - bit more flexible. [William Rowe] - - *) Charset translation: mod_charset_lite handles output content - translation in a filter. mod_charset_lite no longer ignores - subrequests. A bunch of cruft related to BUFF's support for - translating request and response bodies was removed. - [Jeff Trawick] - - *) Move the addition of the CORE filter to the post_read_request - hook in http_core.c. This removes the need to add the filter in - multiple places and allows for an SSL module to be added much - simpler. [Ryan Bloom] - - *) SECURITY: CVE-2000-0913 (cve.mitre.org) - Fix a security problem that affects certain configurations of - mod_rewrite. If the result of a RewriteRule is a filename that - contains expansion specifiers, especially regexp backreferences - $0..$9 and %0..%9, then it may be possible for an attacker to - access any file on the web server. [Tony Finch] - - *) Fix a bug where errors that are detected during early request parsing - don't produce visible HTTP error messages at the browser, because - the core_filter wasn't present. [Greg Ames] - - *) Provide apr_socklen_t as a portability aid. - [Victor J. Orlikowski] - - *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2) - as well as a comment arg to the add, adduser and update cmds. - update allows the user to clear or preserve pw/groups/comment. - Fixed a bug in dbmmanage that prevented the check option from - parsing a password followed by :group... text. Corrected the - seed calcualation for Win32 systems, and added -lsdbm support. - [William Rowe] - - *) Configured mod_auth_dbm to compile with sdbmlib under Win32. - [William Rowe] - - *) Avoid a segfault when parsing .htaccess files. An - uninitialized tree pointer was passed to ap_build_config(). - [Jeff Trawick] - - *) Change the way that inet_addr & inet_network are checked for - in APR's configure process to allow BeOS BONE to correctly - find them. With this change BeOS BONE now builds from source - with no problems. [David Reid] - - *) Fix a bug in apr_create_process() for Unix. The NULL signifying - the end of the parameters to execve() was stored in the wrong - location, overlaying the storage beyond the newargs[] array and - also passing uninitialized storage to execve(), which would - sometimes fail with EFAULT. [Jeff Trawick] - - *) Fix a bug parsing configuration file containers. With a sequence - like this in the config file - - <IfModule mod_kilroy.c> - any stuff - </IfModule> - <IfModule mod_lovejoy.c> - (blank line) - any stuff - </IfModule> - - the second container would be terminated at the blank line due to - sediment in the buffer from reading the prior </IfModule> and an - error message would be generated for the real </IfModule> for the - second container. Also due to this problem, any two characters - could be used for "</" in the close of a container. - [Jeff Trawick] - - *) ap_add_filter prototype changed to remove the ctx pointer. The - pointer still remains in the filter structure, but it can not be - a part of the ap_add_filter prototype. The reason is that when - the core uses AddFilter to add a filter to the stack it doesn't - know how to allocate the ctx pointer, or even how much memory should - be allocated. The filters will have to be responsible for allocating - the ctx memory when they need it. - [Ryan Bloom] - - *) Add an AddFilter directive. This directive takes a list of filters - that should be activated for the requested resource. - [Ryan Bloom] - - *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps - some other platforms). [Jeff Trawick] - - *) Modify mod_include to be a filter. Currently, it has only been tested - on actual files, but it should work for CGI scripts too. - [Ryan Bloom] - - *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted - writes. apr_flush() for Unix: handle interrupted writes. - [Jeff Trawick] - - *) NameVirtualHost can now take "*" as an argument instead of - an IP address. This allows you to create a purely name-based - virtual hosting server that does not have any IP addresses in - the configuration file and which ignores the local address - of any connections. PR #5595, PR #4455 [Tony Finch] - - *) Fix some compile warnings in mod_mmap_static.c - [Mike Abbott <mja sgi.com>] - - *) Fix chunking problem with CGI scripts. The general problem was that - the CGI modules were adding an EOS bucket and then the core added an - EOS bucket. The chunking filter finalizes the chunked response when it - encounters an EOS bucket. Because two EOS buckets were sent, we - finalized the response twice. The fix is to make sure we only send one - EOS, by utilizing a flag in the request_rec. - [Ryan Bloom] - - *) apr_put_os_file() now sets up the unget byte appropriately on Unix - and Win32. Previously, the first read from an apr_file_t set up via - apr_put_os_file() would return a '\0'. [Jeff Trawick] - - *) Mod_cgid now creates a single element bucket brigade, with a pipe - bucket, instead of using BUFF's and ap_r*. - [Ryan Bloom] - - *) APRVARS.in no longer overwrites the EXTRA_LIBS variable. - [Mike Abbott <mja sgi.com>] - - *) Remove ap_bopenf from buff code. This required modifying the file_cache - code to use APR file's directly instead of going through BUFFs. - [Ryan Bloom] - - *) Fix compile break on some platforms for mod_mime_magic.c - [John K. Sterling <sterling covalent.net>] - - *) Fix merging of AddDefaultCharset directive. - PR #5872 (1.3) [Jun Kuriyama <kuriyama imgsrc.co.jp>] - - *) Minor revamp of the rlimit sections of code. We now test - explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit() - is now "available" even if the platform doesn't support - the rlimit family (it's just a noop though). [Jim Jagielski] - - *) Migrate the pre-selection of which MPM to use for specific - platforms to hints.m4, which contains (or should contain) - all platform specific "hints". [Jim Jagielski] - - *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary - [Ryan Bloom] - - *) Add tables with non-string/binary values to APR. - [Ken Coar] - - *) Fix some bad calls to ap_log_rerror() in mod_rewrite. - [Jeff Trawick] - - *) Update PCRE to version 3.2. [Ryan Bloom] - - *) Change the way buckets' destroy functions are called so that - they can be more directly used when changing the type of a - bucket in place. [Tony Finch] - - *) Add generic support for reference-counting the resources used by - buckets, and alter the HEAP and MMAP buckets to use it. Change - the way buckets are initialised to support changing the type of - buckets in place, and use it when setting aside TRANSIENT buckets. - Change the implementation of TRANSIENT buckets so that it can be - mostly shared with IMMORTAL buckets, which are now implemented. - [Tony Finch] - -Changes with Apache 2.0a6 - - *) Add support to Apache and APR for dsos on OS/390. [Greg Ames] - - *) Add a chunking filter to Apache. This brings us one step closer - to removing BUFF. [Ryan Bloom] - - *) ap_add_filter now adds filters in a LIFO fashion. The first filter - added to the stack is the last filter to be called. [Ryan Bloom] - - *) Apache 2.0 has been completely documented using Scandoc. The - docs can be generated by running 'make docs'. [Ryan Bloom] - - *) Add filtered I/O to Apache. This is based on bucket brigades, - Currently the buckets still use BUFF under the covers, but that - should change quickly. The only currently written filter is the - core filter which just calls ap_bwrite. [The Apache Group] - - *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't - built with thread support. [Jeff Trawick] - - *) Abort configuration if --with-layout was specified and there's - no layout definition file. [Ken Coar] - - *) Add support for '--with-port=n' option to configure. [Ken Coar] - - *) Add support for extension methods for the Allow response header - field, and an API routine for accessing r->allowed and the - list of extension methods in a unified manner. [Ken Coar] - - *) mod_cern_meta: fix broken file reading loop in scan_meta_file(). - [Rob Simonson <simo us.ibm.com>] - - *) Get xlate builds working again. The apr renaming in 2.0a5 broke - APACHE_XLATE builds. [Jeff Trawick] - - *) A configuration file parsing problem was fixed. When the - configuration file started with an IfModule/IfDefine container, - only the last statement in the container would be retained. - [Jeff Trawick] - -Changes with Apache 2.0a5 - - *) Perchild is serving pages after passing them to different child - processes. There are still a lot of bugs, but this does work. I - have made requests against the same installation of Apache, and had - different servers use different user IDs to serve the responses. - This change moves to using socketpair instead of an AF_UNIX socket. - [Ryan Bloom] - - *) Perchild MPM still doesn't work perfectly, but it is serving pages. - It can't seem to pass between child processes yet, but I think we - are closer now than before. This moves us back to using Unix - Domain Sockets. [Ryan Bloom] - - *) libapr functions and types renamed with apr_ prefix. - #include "apr_compat.h" for 1.3.x backwards compat - [Perl] - - *) Fix problems with APR sockaddr handling on Win32. It didn't always - return the right information on the local socket address. - [Gregory Nicholls <gnicholls level8.com>] - - *) ap_recv() on Win32: Set bytes-read to 0 on error. - [Gregory Nicholls <gnicholls level8.com>] - - *) Add an option to not detach from the controlling terminal without - going into single process mode. This allows for much easier - debugging of the process startup code. [Ryan Bloom] - - *) ab: don't use perror() to report the failure of an APR function. - [Jeff Trawick] - - *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the - scoreboard on graceful restarts. - [Ryan Bloom] - - *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c. - An invalid ap_proc_t was passed to ap_create_process(). - [Jeff Trawick] - - *) Allow modules to register filters. Those filters are still - never called, but this is a step in the right direction. - [Ryan Bloom and Greg Stein] - - *) Register the mod_cgid daemon process for cleanup so that it is - killed at termination if it does not die when the parent gets - SIGTERM. This change is to fix occasional problems where the - process stays around. Bugs in similar logic in mod_rewrite and - mod_include were also fixed. [Jeff Trawick] - - *) Fix a bug in the time handling. Basically, we were imploding a time - in ap_parseHTTPdate, but it had bogus data in the exploded time format. - Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time - uses those two fields to adjust the time value. Because of the HTTP - spec, both of those values can be zero'ed out safely. This fixes - the bug correctly. [Ryan Bloom] - - *) Fix a couple of place in the Windows code where the wrong error - code was being returned. [Gregory Nicholls <gnicholls level8.com>] - - *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet] - - *) Added the APR_EOL_STR macro for platform dependent differences in - logfiles and other raw text (such as all APR files). Fixes logfiles - not terminated with cr/lf sequences in Win32. [William Rowe] - - *) Move all strings functions in APR to src/lib/apr/strings and create - apr_strings.h for the prototypes. [Ryan Bloom] - - *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure - to repeat the syscall until we stop getting EINTR. I noticed a - related problem at termination (SIGTERM) on FreeBSD when using - fcntl(). Apache 1.3 had these new loops too. Also, make the flock() - implementation work properly with child init. Previously, ap_lock() - was essentially a no-op because all children were using different - locks and thus nobody ever blocked. [Jeff Trawick] - - *) The htdocs/ tree has been moved out of the CVS source tree into - a separate area for easier development. This has NO EFFECT on - end-users or Apache installations. [Ken Coar] - - *) Integrate the mod_dav module for WebDAV protocol handling. This - adds the dav and dav_fs modules, the SDBM library, and additional - XML handling utilities. [Greg Stein] - - *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes - [Greg Stein] - - *) Update the lib/expat-lite/ library (bring forward changes from - the Apache 1.3 repository). [Greg Stein] - - *) If sizeof(long long) == sizeof(long), then prefer long in APR - configure.in. [Dave Hill <ddhill zk3.dec.com>] - - *) Add ap_sendfile for Tru64 Unix. Also, add an error message for - machines where sendfile is detected, but nobody has written ap_sendfile. - [Dave Hill <ddhill zk3.dec.com>] - - *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski] - - *) ab would start up more connections than needed, then quit when the - desired number were finished. Also fixed a logic error involving - ab keepalives. [Victor J. Orlikowski] - - *) WinNT: Implement non-blocking pipes with timeouts to communicate - with CGIs. Apache 2.0a4 had non-blocking pipes but without - timeouts (i.e, if a timeout was specified, the pipe reverted to - a full blocking pipe). Now the behaviour is more in line with - Unix non-blocking pipes. - [Bill Stoddard] - - *) WinNT: Implement accept socket reuse. Using mod_file_cache to - cache open file handles along with accept socket reuse enables - Apache 2.0 to serve non-keepalive requests for static files at - 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps - and Apache 2.0 will serve almost 1200 rps on my system). - [Bill Stoddard] - - *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache - supports two config directives, mmapfile (same behavious as - mod_mmap_static) and cachefile. Use the cachefile directive - to cache open file handles. This directive only works on systems - that have implemented the ap_sendfile API. cachefile works today - on Windows NT, but has not been tested on any flavors of Unix. - [Bill Stoddard] - - *) Cleanup the configuration. With the last few changes the - configuration process automatically: - inherits information about how to build from APR. Allowing - APR to inform Apache that it should or should not use -ldl - - Detects which mod_cgi should be used mod_cgi or mod_cgid, - based on the threading model - - Apache calls APR's configure process before finishing it's - configuration processing, allowing for more information flow - between the two. - [Ryan Bloom] - - - *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK - with non-zero argument makes the socket non-blocking. BeOS and - OS/2 already worked this way. [Jeff Trawick] - - *) ap_close() now calls ap_flush() for buffered files, so write - operations work a whole lot better on buffered files. - [Jeff Trawick] - - *) Fix error messages issued from MPMs which explain where to change - compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads). - [Greg Ames] - - *) ap_create_pipe() now leaves pipes in blocking state. (This helps - reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is - now the way that the blocking state of a pipe is manipulated. - ap_block_pipe() is gone. [Jeff Trawick] - - *) Correct the problem where the only local host name that the IP stack - can discover are 'undotted' private names. If no fully qualified - domain name can be identified, the default ServerName will be set to - the machine's IP address string. A warning is always provided if the - ServerName not specified, but assumed. Solves PR6215 [William Rowe] - - *) Repair problems with config file processing which caused segfault - at init when virtual hosts were defined and which caused ServerName to - be ignored when there was no valid DNS setup. [Jeff Trawick] - - *) Removed pointless ap_is_aborted macro function. [Roy Fielding] - - *) Add ap_sendfile implementation for AIX - [Victor J. Orlikowski] - - *) Repair C++ compatibility in ap_config.h, apr_file_io.h, - apr_network_io.h, and apr_thread_proc.h. - [Tyler J. Brooks <tylerjbrooks home.com>, Jeff Trawick] - - *) Bring the allocation and pool debugging code back into a working - state. This will need to be tested as so far it's only been used on - BeOS. [David Reid] - - *) Change configuration command setup to be properly typesafe when in - maintainer mode. Note that this requires a compiler that can initialise - unions. [Ben Laurie] - - *) Turn on buffering for config file reads. Part of this was to - repair buffered I/O support in Unix and implement buffered - ap_fgets() for all platforms. [Brian Havard, Jeff Trawick] - - *) Win32: Fix problem where UTC offset was not being set correctly - in the access log. Problem reported on news group by Jerry Baker. - [Bill Stoddard] - - *) Fix segfault when reporting this type of syntax error: - "</container> without matching <container> section", where - container is VirtualHost or Directory or whatever. - [Jeff Trawick] - - *) SECURITY: CVE-2000-1204 (cve.mitre.org) - Prevent the source code for CGIs from being revealed when - using mod_vhost_alias and the CGI directory is under the document root - and a user makes a request like http://www.example.com//cgi-bin/cgi - as reported in <news:960999105.344321 ernani.logica.co.uk> - [Tony Finch] - - *) Add support for the new Beos NetwOrking Environment (BONE) - [David Reid] - - *) xlate: ap_xlate_conv_buffer() now tells the caller when the - final input char is incomplete; ap_bwrite_xlate() now handles - incomplete final input chars. [Jeff Trawick] - - *) Yet another update to saferead/halfduplex stuff -- need to ensure - that a bhalfduplex call occurs before logging or else DNS and - such can delay the last packet of the response. [Dean Gaudet] - - *) Some syscall reduction in APR on unix -- don't seek when setting - up an mmap; and don't fcntl() more than once per socket. - [Dean Gaudet] - - *) When mod_cgid is started as root, the cgi daemon now switches - to the configured User/Group (like other httpd processes) - instead of continuing as root. [Jeff Trawick] - - *) The prefork MPM now uses an APR lock for the accept() mutex. - It has not been getting a lock at all recently. httpd -V now - displays APR's selection of the lock mechanism instead of the - symbols previously respected by prefork. [Jeff Trawick] - - *) Change the mmap() feature test to check only for existence. - The previous check required features not used by Apache. - [Greg Ames] - - *) Fix a couple of bugs in mod_cgid: The cgi arguments were - sometimes mangled. The len parm to accept() was not - initialized, leading sometimes to an endless loop of failed - accept() calls on OS/390 and anywhere else that failed the call - if the len was negative. Use <sys/un.h> for struct sockaddr_un - instead of declaring it ourselves to fix a compilation problem - on Solaris. [Jeff Trawick] - - *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom] - - *) Fix zombie process problem with mod_cgi. [Jeff Trawick] - - *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames] - - *) Fix storage overlay when loading dsos. Symptom: Apache dies at - initialization if ALLOC_DEBUG is defined; no known symptom - otherwise. [Jeff Trawick] - - *) Fix typo in configure script when checking for mod_so. bash - doesn't seem to have a problem but /bin/sh on Solaris does. - Symptom: "./configure: test: unknown operator ==" - [Jeff Trawick] - - *) Rebind the Win32 NT and 9x services control into the MPM. - All console, WinNT SCM and Win9x pseudo-service control code is - now wrapped within the WinNT MPM. - [William Rowe] - - *) Make a copy of getenv("PATH") before storing for later use. Some - getenv() implementations use the same storage for successive calls. - CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick] - - *) Server Tokens work in 2.0 again. This also propogates the change - to allow just the product name in the server string using - PRODUCT_ONLY. - [Ryan Bloom] - -Changes with Apache 2.0a4 - - *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers - won't need to call it. [Greg Ames, Jeff Trawick] - - *) Move pre_config hook call to between configuration read and config - tree walk. This allows all modules to implement pre_config hooks - and know that they will be called at an appropriate time. - [Ryan Bloom] - - *) mod_cgi, mod_cgid: Make ScriptLog directive work again. - [Jeff Trawick] - - *) Add pre-config hooks back to all modules. - [Ryan Bloom] - - *) Fix a SIGSEGV in ap_md5digest(), which is used when you have - ContentDigest enabled and we can't/don't mmap the file. - [Jeff Trawick] - - *) We now report the correct line number for syntax errors in config - files. [Ryan Bloom, Greg Stein, Jeff Trawick] - - *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t- - related bugs, and changed shmem/locking to use apr API. Shared-mem - is currently disabled, however, because of problems with graceful - restarts. [Ronald Tschalär] - - *) Fix corruption of IFS variable in --with-module= handling. - Depending on the user's shell or customization thereof, there - would be errors generating ap_config_auto.h later in the configure - procedure. [Jeff Trawick] - - *) mod_cgi: Restore logging of stderr from child process when ScriptLog - isn't used (as in 1.3), except that on Unix it is now logged via - ap_log_rerror() instead of by the child having STDERR_FILENO refer - to the error log. [Greg Ames, Jeff Trawick] - - *) Add '-D' argument processing for run time configuration defines. - [William Rowe] - - *) Organize http_main.c as independent code, such that no code or - global data is exported from it. WIN32 will dynamically link it - to the server core, so this will prevent mutual dependency. - [William Rowe] - - *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD() - and APR_VAR_EXPORT to correctly resolve apr functions and globals. - [William Rowe] - - *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers. - [William Rowe, Jan Just Keijser <KEIJSERJJ logica.com>] - - *) Add mod_charset_lite for configuring character set translation. - [Jeff Trawick] - - *) Add '-n' option to htpasswd to make it print its user:pw record - on stdout rather than having to frob a text file. [Ken Coar] - - *) Fix saferead. Basically, we flush the output buffer if a read on the - input will block. - [Ryan Bloom] - - *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not - a conversion is single-byte only. [Jeff Trawick] - - *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that - the BeOS 5.0 documentation says that shutdown doesn't work yet. - [Roy Fielding] - - *) Fix some minor errors where pid was being manipulated as an int - instead of the portable pid_t. [Roy Fielding] - - *) Fix some error log prints that were printing the pointer to a - structure rather than the pid within the structure. - [Jeff Trawick, Roy Fielding] - - *) ab: Fix a command-line processing bug; track bad headers in - err_response; support reading headers up to 2K. - [Ask Bjoern Hansen <ask valueclick.com>] - - *) Fix ap_resolve_env() so that it handles new function added in a prior - alpha (see "Added the capability to do ${ENVVAR} constructs in the - config file.") as well as the constructs used by mod_rewrite. - [Paul Reder <rederpj raleigh.ibm.com>] - - *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames] - - *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use - APR to perform translation, instead of accessing the hard-coded tables - in 1.3's ebcdic.c. [Jeff Trawick] - - *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing. - [Jeff Trawick] - - *) Add the ability to hook into the config file reading phase. Basically - if a directive is specified EXEC_ON_READ, then when that directive is - read from the config file, the assocaited function is executed. This - should only be used for those directives that must muck with HOW the - server INTERPRETS the config. This should not be used for directives - that re-order or replace items in the config tree. Those changes should - be made in the pre-config step. - [Ryan Bloom] - - *) Add mod_example to the build system. - [Tony Finch] - - *) APR: Add ap_xlate_conv_byte() to convert one char between single- - byte character sets. [Jeff Trawick] - - *) Pick up various EBCDIC fixes from 1.3 (from Martin - Kraemer and Oliver Reh originally according to the change log). - [Jeff Trawick] - - *) Fix a couple of problems in RFC1413 support (controlled by the - IdentityCheck directive). Apache did not build the request string - properly and more importantly Apache would loop forever if the - would-be ident server dropped the connection before sending a - properly terminated response. [Jeff Trawick] - - *) apxs works in 2.0. - [Ryan Bloom] - - *) Reliable piped logs work in 2.0. - [Ryan Bloom] - - *) Introduce a hash table implementation into APR to be used for - replacing tables and other random data structures in Apache. - [Tony Finch] - - *) Add some more error reporting to htpasswd in the case of problems - generating or accessing the temporary file. Also, pass in a - buffer if the implementation knows how to use it (i.e., if L_tmpnam - is defined). [Ken Coar] - - *) Configure creates config.nice now containing your configure - options. Syntax: ./config.nice [--more-options] - [Sascha Schumann] - - *) Fix various return code problems in APR on Win32. For most of - these, APR was returning APR_EEXIST instead of GetLastError()/ - WSAGetLastError(). [Jeff Trawick] - - *) Make piped logs work again in version 2.0 - [Ryan Bloom] - - *) Add VPATH support to UNIX build system of Apache and APR. - [Sascha Schumann] - - *) Fix ap_tokenize_to_argv to respect the const arguments that are - passed to it. - [Ryan Bloom] - - *) Fix mm's memcpy/memset macros, pointer arithmetic was broken. - Patch submitted to author. - [Sascha Schumann] - - *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require - /sbin in PATH on FreeBSD (all submitted to rse previously) - [Jeff Trawick] - - *) Fix building Pthread-based MPMs on OpenBSD - [Sascha Schumann] PR#26 - - *) Fix ap_readdir() problem on systems where d_name[] field in - struct dirent is declared with only one byte. (This problem only - affected multithreaded builds.) This caused a segfault during - pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at - least). [Jeff Trawick] - - *) Fix some make-portability problems on at least Tru64, Irix - and UnixWare. - [Sascha Schumann] PR#18, PR#39 - - *) Add ap_sigwait() to support old-style sigwait() on systems - like OS/390 and UnixWare. - [Sascha Schumann] - - *) Add POSIX-thread flags for more platforms. - [Sascha Schumann] - - *) Fix some minor bugs in ap_strerror(). Teach ap_strerror() - (on Unix, at least) to handle resolver errors. Fix a bug in - the definition of APR_ENOMEM so that ap_strerror() can spit - out the correct error message for it. - [Jeff Trawick] - -Changes with Apache 2.0a3 - - *) mod_so reports ap_os_dso_error() if ap_dso_load() fails - [Doug MacEachern] - - *) API: *HOOK* macros now have an AP_ prefix - [Doug MacEachern] - - *) Win32: Eliminate redundant calls to initialize winsock. - [Tim Costello <timcostello ozemail.com.au>] - - *) Fix bugs initializing ungetchar for pipes. - [Chia-liang Kao <clkao CirX.ORG>] - - *) The ab program in the src/support directory is now portable using - APR. - [Ryan Bloom] - - *) Support directory is being compiled when the server is built - [Ryan Bloom] - - *) The configure option --with-program-name has been added to allow - developers to rename the executable at configure time. This also - changes the name of the config files to match the executable's name. - [Ryan Bloom] - - *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames - containing version numbers. [Martin Pool] - - *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on - Unix; access_log and error_log now created with these perms; non- - Unix is unaffected [Jeff Trawick] - - *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h. - Replaced more magic numbers with MD5_DIGESTSIZE. - [William Rowe, Roy Fielding] - - *) Win32: Get mod_auth_digest compiling and added to the Windows - build environment. Not tested and I'd be suprised if it - actually works. [Bill Stoddard] - - *) Revamp the Win32 make environment. Makefiles have been removed and - Apache.dsw created to bring together all the pieces. Create new file - os/win32/BaseAddr.ref to define module base addresses (to prevent - dll relocation at start-up). - [William Rowe, Greg Marr, Tim Costello, Bill Stoddard] - - *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most - of the \015, \012, and \015\012 constants with macros. - [Greg Ames] - - *) Add ap_xlate_open() et al for translation of text between different - character sets. The initial implementation requires iconv(). - [Jeff Trawick] - - *) More FAQs and answers from comp.infosystems.www.servers.unix. - [Joshua Slive <slive finance.commerce.ubc.ca>] - - *) CGI output is being timed out now. - [Ryan Bloom] - - *) Fix the problem with dieing quietly. dupfile now takes a pool which - is used by the new apr file. There is no reason to create a new file - with the same lifetime as the original file. - [Ryan Bloom] - - *) Win32: Attempt to eliminate dll relocation at start-up by specifying - module base addresses. This will help shooting seg faults - in the field. [William Rowe <wrowe lnd.com>] - - *) Update Apache on Windows documentation. Add new document - describing how to compile Apache on Windows. - [William Rowe <wrowe lnd.com>] - - *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take - microseconds instead of seconds. Some storage leaks and other - minor bugs in related code were fixed. [Jeff Trawick] - - *) Win32: First cut at getting mod_isapi working under 2.0 - [William Rowe <wrowe lnd.com>] - - *) First stab at getting mod_auth_digest working under 2.0 - quick change summary: - - moved the random byte generation (ap_generate_random_bytes) into APR - - now uses ap_time_t - - compiles and runs on linux - - tested with amaya - [Brian Martin <bmartin penguincomputing.com>] - - *) Win32: Move the space stripping of physical service names - fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an - unresolved symbol. Add dependency checking to the - CreateService call to ensure TCPIP and AFP (winsock) is started - before Apache. - [William Rowe <wrowe lnd.com>] - - *) Win32: Add code to perform latebinding on functions that may - not exist on all levels of Windows where Apache runs. This - is needed to allow Apache to start-up on Win95/98. All calls - to non portable functions should be protected with - ap_oslevel checks to prevent runtime segfaults. - [William Rowe <wrowe lnd.com>] - - *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer] - - *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick] - - *) Win32: Get non-blocking CGI pipe reads working under Windows NT. - This addresses PR 1623. Still need to address timing out runaway - CGI scripts. [Bill Stoddard] - - *) Win32: Make ap_stat Windows 95/98 friendly - [William Rowe <wrowe lnd.com>] - - *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to - always fail. Need to initialise the dwOSVersionInfoSize member of the - OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx - always fails. - - The patch also enhances ap_get_oslevel (and the associated enum) to - handle selected service packs for NT4, and adds recognition for - Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then - we can use ReadFileScatter and WriteFileGather in readwrite.c. - [Tim Costello <Tim.Costello BTFinancialgroup.com>] - - *) Get mod_rewrite building and running, and mod_status building for Win NT - [Allan Edwards <ake raleigh.ibm.com>] - - *) Patch to port mod_auth_db to the 2.0 api and also to support - Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and - 2.7.7. It should work with version 1 as well but I haven't tested it. - [Brian Martin <bmartin penguincomputing.com>] - - *) Get APR DSO code working under Windows. Includes cross platform - fixes to mod_so.c. - [<Tim.Costello BTFinancialgroup.com>] - - *) Fix some of the Windows APR time functions. - [William Rowe] - - *) FAQ changes related to tidying up historical documents on the web site. - [Joshua Slive <slive finance.commerce.ubc.ca>] - - *) Move Windows DSO code into APR. - [Bill Stoddard] - - *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause). - Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw - at build time. At this point, the server will not compile on Windows because - of the recent DSO commits. Fixing those next. - [Bill Rowe & Bill Stoddard] - - *) Added error checking for file I/O APR routines. - [Jon Travis <jtravis covalent.net>] - - *) APR: Don't use the values of resolver error codes for the - corresponding APR error codes. On Unix and Win32, return the - proper APR error code after a resolver error. [Jeff Trawick] - -Changes with Apache 2.0a2 - - *) Renamed the executable back to httpd on all platforms other - than Win32 - [Ryan Bloom] - - *) Allow BeOS to survive restarts, log properly and a few - small things it had problems with due to the way it setup - users and groups. [David Reid] - - *) Get mod_rewrite working with APR locks - [Paul Reder <rederpj raleigh.ibm.com>] - - *) Actually remove the sempahore when the lock cleanup routine - is called on BeOS. [David Reid] - - *) Clear hook registrations between reads of the config file. - When DSOs are unloaded and re-loaded the old hook pointers may - no longer be valid. This fix eliminates potential segfaults. - [Allan Edwards <ake raleigh.ibm.com>] - - *) Fix a problem with Sigfunc not being defined or bypassed - if sigaction() wasn't found. [Jim Jagielski] - - *) Fix the locking mechanism on BSD variants. They now use fcntl - locks. This allows the server to start and serve pages. - [Ryan Bloom] - - *) First cut at getting the Win32 installer to work - [William Rowe <wrowe lnd.com>] - - *) Get htpasswd compiling under Windows - [William Rowe <wrowe lnd.com>] - - *) Change the log message for a bind() failure to show the - interface and port number. [Jeff Trawick] - - *) Import the documentation from 1.3.12 and bring parts of it - up-to-date with respect to the changes that have occurred - in 2.0. - [Tony Finch] - - *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses - now logged correctly on BeOS. - [David Reid] - - *) Create one makefile for all Win32 distributions (NT/2000/95/98). - Makefile.win includes the same user interface as the old - Makefile.nt - [William Rowe <wrowe lnd.com>, Jeff Trawick <trawick us.ibm.com>] - - *) Win32 exec now uses COMSPEC environment string for command - shell path resolution. - [William Rowe <wrowe lnd.com>] PR#3715 - - *) Win32: ap_connect() was not returning correct error condition - PR5866 - [Allen Prescott <allen clanprescott.com>] - - *) Win32: ap_open() was broken on Win9x because an NT-specific - flag was passed to CreateFile. ap_puts() added an unnecessary - '\n'. - [Jeff Trawick <trawick us.ibm.com>] - - *) Put in Korean and Norwegian index.html pages (2.0 and 1.3) - which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed' - confusing ee/et name and made all extensions language/dialect - rather than country reflecting. Changed example files to - explicit reflect the ISO charset and added a few common - ones to the example config [dirkx] - - *) Extend external module capability. To use this, you call - configure with --with-module=path/to/mod1,path/to/mod2,etc. - [Ryan Bloom] - - *) Backported the various "default charset" fixes from 1.3.12, - including the AddDefaultCharset directive. [Jim Jagielski] - - *) Added the capability to do ${ENVVAR} constructs in the - config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited - it does this on a line by line basis; i.e. if the envvar - expands to something with spaces you have to protect it - by adding quotes around it (Unless of course you expect it - to contains more than one argument. Alternatively you - can compile it on a per token basis; which is what people - usually expect by setting RESOLVE_ENV_PER_TOKEN. But this - hampers fancier hacks. - [Dirk-Willem van Gulik] - - *) Changed the 'ErrorDocument' syntax in that it NO longer - supports the asymetric - - ErrorDocument 301 "Some message - - Note the opening " quote, without a closing quote. It now - has either the following syntaxes - - ErrorDocument XXX /local/uri - ErrorDocument XXX http://valid/url - ErrorDocument XXX "Some Message" - - The recognition heuristic is: if it has a space it - is a message. If it has no spaces and starts with a / - or is a valid URL then treat it that way. Otherwise it - is assumed to be a message. - - This breaks backward compatibility but makes live a hell - of a lot easier for GUI's and config file parsers. - [Dirk-Willem van Gulik] - - *) Changed 'CacheNegotiatedDocs' from its present/not-present - syntax into a 'on' or 'off' syntax. As it currently is the - only non nesting token which uses NO_ARGS and thus is an - absolute pain for any config interface automation. This - breaks backward compatibility. [Dirk-Willem van Gulik] - - *) Add ability to add external modules to the build process. This is - done with --with-module=/path/to/module. Modules can only be added - as static modules at this point. - [Ryan Bloom] - -Changes with Apache 2.0a1 - - *) Fix FreeBSD 3.3 core dump. - Basically, ap_initialize() needs to get called before - create_process(), since create_process() passes op_on structure - to semop() to get a lock, but op_on isn't initialized until - ap_initialize() calls setup_lock(). Here is a slight - rearrangement to main() which calls ap_initialize() earlier... - [Jeff Trawick <trawick us.ibm.com>] - - *) Enable Apache to use sendfile/TransmitFile API - [Bill Stoddard, David Reid, Paul Reder] - - *) Re-Implement Win32 APR network I/O APIs and most of the file I/O - APIs. - [Bill Stoddard] - - *) Make file I/O and network I/O writev/sendv APIs consistent. - Eliminate use of ap_iovec_t and use Posix struct iovec. - Use seperate variable on ap_writev to set the number of iovecs - passed in and number of bytes written. - [Bill Stoddard] - - *) Adapt file iol to use APR functions. Replaced ap_open_file() - with ap_create_file_iol(). ap_create_file_iol() requires that - the file be opened prior to the call using ap_open(). - [Bill Stoddard] - - *) Port mod_include and mod_cgi to 2.0 - [Paul Reder, Bill Stoddard] - - *) ap_send{,v}, ap_recv, ap_sendfile API clarification -- - bytes_read/bytes_written is always valid (never -1). Plus - some fixes to buff.c to correct problems introduced by the - errno => ap_status_t changes a while back. Plus a fix to - chunked encoding introduced right at the beginning of 2.0. - [Dean Gaudet] - - *) Revamped UNIX build system to use autoconf and libtool. - [Manoj Kasichainula, Sascha Schumann] - - *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj raleigh.ibm.com>] - - *) SECURITY: More rigorous checking of Host: headers to fix security - problems with mass name-based virtual hosting (whether using mod_rewrite - or mod_vhost_alias). - [Ben Hyde, Tony Finch] - - *) Add back support for UseCanonicalName in <Directory> containers. - [Manoj Kasichainula] - - *) Added APLOG_STARTUP log type. This allows us to write an error - message without any of the date and time information. As a part - of this change, I also removed all of the calls to fprintf(stderr - and replaced them with calls to ap_log_error using APLOG_STARTUP - writing to stderr is no longer portable, because we don't direct - stderr to the error log on all platforms. - [Ryan Bloom] - - *) Convert error logging functions to take errno as an argument. - This makes our error logs more portable, because some Windows API's - don't set errno. This change allows us to still output a valid - message on all of our platforms. - [Ryan Bloom] - - *) mod_mime_magic runs in 2.0-dev now. - [Paul Reder <rederpj raleigh.ibm.com>] - - *) sendfile has been added to APR. - [John Zedlewski <zedlwski Princeton.EDU>] - - *) buff.c has been converted to no longer use errno. - [Manoj Kasichainula] - - *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and - interface adaption to APR functions did it. [Martin Kraemer] - - *) Support DSOs properly on 32-bit HP-UX 11.0 - [Dilip Khandekar <dilip cup.hp.com>] - - *) Updated MM in APR source tree from version 1.0.8 to 1.0.11 - [Ralf S. Engelschall] - - *) Cleaned APR build environment integration and bootstrap APR - automatically for developers from src/Configure. - [Ralf S. Engelschall] - - *) Fixed building of src/support/htpasswd.c - [Ralf S. Engelschall] - - *) When generating the Location: header, mod_speling forgot - to escape the spelling-fixed uri. (Forw-Port from 1.3) - [Martin Kraemer] - - *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding] - - *) Change all pools to APR contexts. This is the first step to - incorporating APR into Apache. [Ryan Bloom] - - *) Move "handler not found" warning message to below the check - for a wildcard handler. [Dirk <dirkm teleport.com>, Roy Fielding] - PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807 - - *) Support line-continuation feature in config.option file and - allow the loading of multiple option sections at once via - ``--with-option=<section1>,<section2>,...'' - [Ralf S. Engelschall] - - *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding] - -Changes with Apache MPM - - *) Use asynchronous AcceptEx() and a completion port to accept and - dispatch connections to threads in Windows NT/2000. - [Bill Stoddard] - - *) Implement WINNT Win32 MPM from original Win32 code in http_main.c - [Bill Stoddard] - - *) Implement the APACI --with-option facility - (per default used the config.option file). - [Ralf S. Engelschall] - - *) MPM BEOS port. [David Reid <abb37 dial.pipex.com>] - - *) Start to implement module-defined hooks that are a) fast and b) typesafe. - Replace pre_connection module call with a register_hook call and - implement pre_connection as a hook. The intent is that these hooks will - be extended to allow Apache to be multi-protocol, and also to allow the - calling order to be specified on a per-hook/per-module basis. - [Ben Laurie] - - *) Implement mpm_* methods as "modules". Each method gets its own - subdir in src/modules (eg: src/modules/prefork). Selection - of method uses Rule MPM_METHOD. [Jim Jagielski] - - *) Port the hybrid server from the apache-apr repository as - mpm_mpmt_pthread. [Manoj Kasichainula] - - *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common - amongst the unix MPMs. - - *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the - signal handling for the new world order. [Dean Gaudet] - - *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out - of alloc.c for now. [Dean Gaudet] - - *) Handle partial large writes correctly. [Ben Laurie] - - *) Eliminate conn_rec's pointer to server. All it knows is the base server - based on IP/port. [Ben Laurie] - - *) Port a bunch of modules to the new module structure. - ["Michael H. Voase" <mvoase midcoast.com.au>] - - *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet] - - *) Basic restructuring to introduce the MPM concept; includes various - changes to the module API... better described by - docs/initial_blurb.txt. [Dean Gaudet] - -Changes with Apache pthreads - - *) New buff option added: BO_TIMEOUT. It describes the timeout for - buff operations (generally over a network). - [Dean Gaudet, Ryan Bloom, Manoj Kasichainula] - - *) Created http_accept abstraction. Added 4 new functions (not exported): - init_accept(), begin_accepting_requests(), get_request(), - stop_accepting_requests() [Bill Stoddard] - - *) Fix to ap_rprintf call that allows mod_info to work properly. - [James Morris <jmorris intercode.com.au>] - - *) user and ap_auth_type fields were moved from connection_rec to - request_rec. [Ryan Bloom] - - *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't - needed in a threaded server. - - *) Initial pthread implementation from from Dean's apache-nspr code. - [Bill Stoddard, Ryan Bloom] - - -Changes with Apache 1.3.x and later: - - *) http://svn.apache.org/viewvc/httpd/httpd/branches/1.3.x/src/CHANGES?view=markup |
