[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.

[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.

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.

[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.

[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().

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.

[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.

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.

[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.

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.

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.

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.

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.

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.

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.

[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.
