-*- coding: utf-8 -*- Changes with Apache 2.3.0 [ When backported to 2.2.x, remove entry from this file ] *) mod_auth_form: Add a module capable of allowing end users to log in using an HTML form, storing the credentials within mod_session. [Graham Leggett] *) Add a function to the http filters that is able to parse an HTML form request with the type of application/x-www-form-urlencoded. [Graham Leggett] *) mod_session_crypto: Initialise SSL in the post config hook. [Ruediger Pluem, Graham Leggett] *) mod_session_dbd: Add a session implementation capable of storing session information in a SQL database via the dbd interface. Useful for sites where session privacy is important. [Graham Leggett] *) mod_session_crypto: Add a session encoding implementation capable of encrypting and decrypting sessions wherever they may be stored. Introduces a level of privacy when sessions are stored on the browser. [Graham Leggett] *) mod_session_cookie: Add a session implementation capable of storing session information within cookies on the browser. Useful for high volume sites where server bound sessions are too resource intensive. [Graham Leggett] *) mod_session: Add a generic session interface to unify the different attempts at saving persistent sessions across requests. [Graham Leggett] *) core, authn/z: Avoid calling access control hooks for internal requests with configurations which match those of initial request. Revert to original behaviour (call access control hooks for internal requests with URIs different from initial request) if any access control hooks or providers are not registered as permitting this optimization. Introduce wrappers for access control hook and provider registration which can accept additional mode and flag data. [Chris Darroch] *) http_filters: Don't spin if get an error when reading the next chunk. PR 44381 [Ruediger Pluem] *) mod_dav: Return "method not allowed" if the destination URI of a WebDAV copy / move operation is no DAV resource. PR 44734 [Ruediger Pluem] *) Introduced ap_expr API for expression evaluation. This is adapted from mod_include, which is the first module to use the new API. [Nick Kew] *) mod_authz_dbd: When redirecting after successful login/logout per AuthzDBDRedirectQuery, do not report authorization failure, and use first row returned by database query instead of last row. [Chris Darroch] *) mod_rewrite: Initialize hash needed by ap_register_rewrite_mapfunc early enough. PR 44641 [Daniel Lescohier ] *) mod_authn_dbd: Disambiguate and tidy database authentication error messages. PR 43210. [Chris Darroch, Phil Endecott ] *) mod_cache: Handle If-Range correctly if the cached resource was stale. PR 44579 [Ruediger Pluem] *) mod_speling: remove regression from 1.3/2.0 behavior and drop dependency between mod_speling and AcceptPathInfo. PR 43562 [Jose Kahan ] *) mod_ldap: Correctly return all requested attribute values when some attributes have a null value. PR 44560 [Anders Kaseorg ] *) core: check symlink ownership if both FollowSymlinks and SymlinksIfOwnerMatch are set [Nick Kew] *) core: fix origin checking in SymlinksIfOwnerMatch PR 36783 [Robert L Mathews ] *) rotatelogs: Added '-f' option to force rotatelogs to create the logfile as soon as started, and not wait until it reads the first entry. [Jim Jagielski] *) mod_proxy: Do not try a direct connection if the connection via a remote proxy failed before and the request has a request body. [Ruediger Pluem] *) mod_substitute: The default is now flattening the buckets after each substitution. This was mostly done to abide by the Principle Of Least Astonishment. The newly added 'q' flag allows for the quicker, more efficient bucket-splitting if the user so desires. [Jim Jagielski] *) Added 'disablereuse' option for ProxyPass which, essentially, disables connection pooling for the backend servers. [Jim Jagielski] *) Activate mod_cache, mod_file_cache and mod_disc_cache as part of the 'most' set for '--enable-modules' and '--enable-shared-mods'. Include mod_mem_cache in 'all' as well. [Dirk-Willem van Gulik] *) Also install mod_so.h, mod_rewrite.h and mod_cache.h; as these contain public function declarations which are useful for third party module authors. PR 42431 [Dirk-Willem van Gulik]. *) mod_dir, mod_negotiation: pass the output filter information to newly created sub requests; as these are later on used as true requests with an internal redirect. This allows for mod_cache et.al. to trap the results of the redirect. [Dirk-Willem van Gulik, Ruediger Pluem] *) ab: Use a 64 bit unsigned int instead of a signed long to count the bytes transferred to avoid integer overflows. PR 44346 [Ruediger Pluem] *) mod_proxy_ajp: Do not retry request in the case that we either failed to sent a part of the request body or if the request is not idempotent. PR 44334 [Ruediger Pluem] *) rotatelogs: Don't leak memory when reopening the logfile. PR 40183 [Ruediger Pluem, Takashi Sato ] *) mod_ldap: Add support (taking advantage of the new APR capability) for ldap rebind callback while chasing referrals. This allows direct searches on LDAP servers (in particular MS Active Directory 2003+) using referrals without the use of the global catalog. PRs 26538, 40268, and 42557 [Paul J. Reder] *) ab: Do not try to read non existing response bodies of HEAD requests. PR 34275 [Takashi Sato ] *) Support chroot on Unix-family platforms PR 43596 [Dimitar Pashev ] *) mod_proxy_http: Return HTTP status codes instead of apr_status_t values for errors encountered while forwarding the request body PR 44165 [Eric Covener] *) mod_ssl: Added server name indication support (SNI, RFC 4366). PR 34607. [Kaspar Brand ]. A test configuration can be created with test/make_sni.sh [Dirk-Willem van Gulik]. *) ApacheMonitor.exe: Introduce --kill argument for use by the installer. This will permit the installation tool to remove all running instances before attempting to remove the .exe. [William Rowe] *) mod_proxy: Lower memory consumption for short lived connections. PR 44026. [Ruediger Pluem] *) mod_proxy: Keep connections to the backend persistent in the HTTPS case. [Ruediger Pluem] *) rotatelogs: Improve atomicity when using -l and cleaup code. PR 44004 [Rainer Jung] *) mod_ssl: Add support for OCSP validation of client certificates. PR 41123. [Marc Stern , Joe Orton] *) mod_unique_id: Fix timestamp value in UNIQUE_ID. PR 37064 [Kobayashi ] *) mod_serf: New module for Reverse Proxying. [Paul Querna] *) core: Add the option to keep aside a request body up to a certain size that would otherwise be discarded, to be consumed by filters such as mod_include. When enabled for a directory, POST requests to shtml files can be passed through to embedded scripts as POST requests, rather being downgraded to GET requests. [Graham Leggett] *) mod_ssl: Fix TLS upgrade (RFC 2817) support. PR 41231. [Joe Orton] *) scoreboard: Correctly declare ap_time_process_request. PR 43789 [Tom Donovan ] *) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member from the connection rec, ap_get_scoreboard_worker(proc, thread) will now provide the unusual legacy lookup. [William Rowe] *) mpm winnt: fix null pointer dereference PR 42572 [Davi Arnaut] *) core: reinstate location walk to fix config for subrequests PR 41960 [Jose Kahan ] *) mod_log_config: Add format options for %p so that the actual local or remote port can be logged. PR 43415. [Adam Hasselbalch Hansen , Ruediger Pluem, Jeff Trawick] *) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn parameters to the environment. Improve portability to EBCDIC machines by using apr_toupper(). [Martin Kraemer] *) mod_ldap, mod_authnzldap: Add support for nested groups (i.e. the ability to authorize an authenticated user via a "require ldap-group X" directive where the user is not in group X, but is in a subgroup contained in X. PR 42891 [Paul J. Reder] *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna] *) ab: Add -r option to continue after socket receive errors. [Filip Hanik ] *) mod_ldap: Fix the search limit parameter to ldap_search_ext_s() for SDKs that define LDAP_NO_LIMIT to something other than -1. [David Jones ] *) apxs: Enhance -q flag to print all known variables and their values when invoked without variable name(s). [William Rowe, Sander Temme] *) apxs: Eliminate run-time check for mod_so. PR 40653. [David M. Lee ] *) beos MPM: Create pmain pool and run modules' child_init hooks when entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run(). [Chris Darroch] *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that cleanups registered in modules' child_init hooks are performed. [Chris Darroch] *) mod_dbd: Stash DBD connections in request_config of initial request only, or else sub-requests and internal redirections may cause entire DBD pool to be stashed in a single HTTP request. [Chris Darroch] *) Fix issue which could cause error messages to be written to access logs on Win32. PR 40476. [Tom Donovan ] *) The LockFile directive, which specifies the location of the accept() mutex lockfile, is deprecated. Instead, the AcceptMutex directive now takes an optional lockfile location parameter, ala SSLMutex. [Jim Jagielski] *) mod_authn_dbd: Export any additional columns queried in the SQL select into the environment with the name AUTHENTICATE_. This brings mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett] *) mod_dbd: Key the storage of prepared statements on the hex string value of server_rec, rather than the server name, as the server name may change (eg when the server name is set) at any time, causing weird behaviour in modules dependent on mod_dbd. [Graham Leggett] *) mod_proxy_fcgi: Added win32 build. [Mladen Turk] *) sendfile_nonblocking() takes the _brigade_ as an argument, gets the first bucket from the brigade, finds it not to be a FILE bucket and barfs. The fix is to pass a bucket rather than a brigade. [Niklas Edmundsson ] *) mod_rewrite: support rewritemap by SQL query [Nick Kew] *) ap_get_server_version() has been removed. Third-party modules must now use ap_get_server_banner() or ap_get_server_description(). [Jeff Trawick] *) All MPMs: Introduce a check_config phase between pre_config and open_logs, to allow modules to review interdependent configuration directive values and adjust them while messages can still be logged to the console. Handle relevant MPM directives during this phase and format messages for both the console and the error log, as appropriate. [Chris Darroch] *) mod_proxy: don't URLencode tilde in path component [Stijn Hoop ] *) mpm_winnt: Fix return values from wait_for_many_objects. The return value is index to the signaled thread in the creted_threads array. We can not use WAIT_TIMEOUT because his value is defined as 258, thus limiting the MaxThreads to that value. [Mladen Turk] *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir to circumvent the symbolic link checks imposed by FollowSymLinks and SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe] *) mod_proxy: Support environment variable interpolation in reverse proxying directives. [Nick Kew] *) core: Add the filename of the configuration file to the warning message about the useless use of AllowOverride. PR 39992. [Darryl Miles ] *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ] configures the I/O Dump of SSL traffic, when LogLevel is set to Debug. The default is none as this is far greater debugging resolution than the typical administrator is prepared to untangle. [William Rowe] *) mod_disk_cache: If possible, check if the size of an object to cache is within the configured boundaries before actually saving data. [Niklas Edmundsson ] *) mod_cache: Convert all values to seconds before comparing them when checking whether to send a Warning header for a stale response. PR 39713. [Owen Taylor ] *) mod_disk_cache: Delete temporary files if they cannot be renamed to their final name. [Davi Arnaut ] *) Worker and event MPMs: Remove improper scoreboard updates which were performed in the event of a fork() failure. [Chris Darroch] *) Add support for fcgi:// proxies to mod_rewrite. [Markus Schiegl ] *) Remove incorrect comments from scoreboard.h regarding conditional loading of worker_score structure with mod_status, and remove unused definitions relating to old life_status field. [Chris Darroch ] *) Remove allocation of memory for unused array of lb_score pointers in ap_init_scoreboard(). [Chris Darroch ] *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy. [Garrett Rooney, Jim Jagielski, Paul Querna] *) Event MPM: Fill in the scoreboard's tid field. PR 38736. [Chris Darroch ] *) mod_charset_lite: Remove Content-Length when output filter can invalidate it. Warn when input filter can invalidate it. [Jeff Trawick] *) Authz: Add the new module mod_authn_core that will provide common authn directives such as 'AuthType', 'AuthName'. Move the directives 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias into mod_authn_core. [Brad Nicholes] *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy' into the new module mod_access_compat which can be loaded to provide support for these directives. [Brad Nicholes] *) Authz: Move the 'Require' directive from the core module as well as add the directives '', '', '' and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR' logic into the authorization processing. [Brad Nicholes] *) Authz: Add the new module mod_authz_core which acts as the authorization provider vector and contains common authz directives. [Brad Nicholes] *) Authz: Renamed mod_authz_dbm authz providers from 'group' and 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes] *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle host-based access control provided by mod_authz_host and invoked through the 'Require' directive. [Brad Nicholes] *) Authz: Convert all of the authz modules from hook based to provider based. [Brad Nicholes] *) mod_cache: Add CacheMinExpire directive to set the minimum time in seconds to cache a document. [Brian Akins , Ruediger Pluem] *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew] *) Fix typo in ProxyStatus syntax error message. [Christophe Jaillet ] *) Asynchronous write completion for the Event MPM. [Brian Pane] *) Added an End-Of-Request bucket type. The logging of a request and the freeing of its pool are now done when the EOR bucket is destroyed. This has the effect of delaying the logging until right after the last of the response is sent; ap_core_output_filter() calls the access logger indirectly when it destroys the EOR bucket. [Brian Pane] *) Rewrite of logresolve support utility: IPv6 addresses are now supported and the format of statistical output has changed. [Colm MacCarthaigh] *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane] *) Added new connection states for handler and write completion [Brian Pane] *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264. [Justin Erenkrantz] *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive, allowing string-valued client certificate attributes to be used for access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1") [Martin Kraemer, David Reid] [Apache 2.1.0-dev includes those bug fixes and changes with the Apache 2.2.xx tree as documented, and except as noted, below.] Changes with Apache 2.2.x and later: *) http://svn.apache.org/viewvc/httpd/httpd/branches/2.2.x/CHANGES?view=markup Changes with Apache 2.0.x and later: *) http://svn.apache.org/viewvc/httpd/httpd/branches/2.0.x/CHANGES?view=markup Changes with Apache 1.3.x and later: *) http://svn.apache.org/viewvc/httpd/httpd/branches/1.3.x/src/CHANGES?view=markup
