-*- coding: utf-8 -*- Changes with Apache 2.3.0 [ When backported to 2.2.x, remove entry from this file ] *) mod_proxy_connect: avoid segfault on DNS lookup failure. PR 40756 [Trevin Beattie ] *) mod_proxy: enable Ignore Errors option on ProxyPass Status. PR 43167 [Francisco Gimeno *) mod_proxy_http: Don't try to read body of a HEAD request before responding. PR 41644 [Stuart Children ] *) mod_autoindex: Add in Type and Charset options to IndexOptions directive. This allows the admin to explicitly set the content-type and charset of the generated page. [Jim Jagielski] *) mime.types: Many updates to sync with IANA registry and common unregistered types that the owners refuse to register. Admins are encouraged to update their installed mime.types file. PR: 35550, 37798, 39317, 31483 [Roy T. Fielding] *) log core: ensure we use a special pool for stderr logging, so that the stderr channel remains valid from the time plog is destroyed, until the time the open_logs hook is called again. [William Rowe] *) main core: Emit errors during the initial apr_app_initialize() or apr_pool_create() (when apr-based error reporting is not ready). [William Rowe, Jeff Trawick] *) mpm_winnt: Prevent the parent-child pipe from leaking into other spawned processes, and ensure we have a /Device/null handle for stdout when running as-a-service. [William Rowe] *) log core: fix the new piped logger case where we couldn't connect the replacement stderr logger's stderr to the NULL stdout stream. Continue in this case, since the previous alternative of no error logging at all (/dev/null) is far worse. [William Rowe] *) mod_ldap: Avoid possible crashes, hangs, and busy loops due to improper merging of the cache lock in vhost config PR 43164 [Eric Covener] *) mod_negotiation: preserve Query String in resolving a type map PR 33112 [Jørgen Thomsen , Nick Kew] *) mod_deflate: fix content_encoding detection in inflate_out filter when it's not in response headers table. PR 42993 [Nick Kew] *) mod_proxy: Improve network performance by setting APR_TCP_NODELAY (disable Nagle algorithm) on sockets if implemented. PR 42871 [Christian BOITEL , Jim Jagielski] *) mod_info: mod_info outputs invalid XHTML 1.0 transitional. PR 42847 [Rici Lake ] *) mime.types: add registered Apple installer type PR 40379 [Peter Bierman ] *) 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_deflate: don't try to process metadata buckets as data. what should have been a 413 error was logged as a 500 and a blank screen appeared at the browser. [Greg Ames, Ruediger Pluem] *) SECURITY: CVE-2007-3304 (cve.mitre.org) prefork, worker, event MPMs: Ensure that the parent process cannot be forced to kill processes outside its process group. [Joe Orton] *) SECURITY: CVE-2006-5752 (cve.mitre.org) mod_status: Fix a possible XSS attack against a site with a public server-status page and ExtendedStatus enabled, for browsers which perform charset "detection". Reported by Stefan Esser. [Joe Orton] *) Event MPM: Add support for running under mod_ssl, by reverting to the Worker MPM behaviors, when run under an input filter that buffers its own data. [Paul Querna] *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna] *) SECURITY: CVE-2007-1862 (cve.mitre.org) mod_mem_cache: Copy headers into longer lived storage; header names and values could previously point to cleaned up storage PR 41551 [Davi Arnaut ] *) mod_cache: Do not set Date or Expires when they are missing from the original response or are invalid. [Justin Erenkrantz] *) mod_cache: Correctly handle HEAD requests on expired cache content. PR 41230. [Niklas Edmundsson] *) mod_proxy: Added ProxyPassMatch directive, which is similar to ProxyPass but takes a regex local path prefix. [Jim Jagielski] *) mod_so: Solve dev's confusion by reporting expected/seen module magic signatures when failing with a 'garbled' message, and solve user's confusion by pointing out 'perhaps compiled for a different version of apache?'. [William Rowe] *) mod_substitute: Added a new experimental output filter, which performs inline response content pattern matching (including regex) and substitution. [Jim Jagielski] *) mod_ssl: Version reporting update; displays 'compiled against' Apache and build-time SSL Library versions at loglevel [info], while reporting the run-time SSL Library version in the server info tags. Helps to identify a mod_ssl built against one flavor of OpenSSL but running against another (also adds SSL-C version number reporting.) [William Rowe] *) core: Change etag generation to produce identical results on 32-bit and 64-bit platforms. PR 40064. [Joe Orton] *) 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 ] *) mod_dbd: Introduce configuration groups to allow inheritance by virtual hosts of database configurations from the main server. Determine the minimal set of distinct configurations and share connection pools whenever possible. Allow virtual hosts to override inherited SQL statements. PR 41302. [Chris Darroch] *) core: Fix broken chunk filtering that causes all non blocking reads to be converted into blocking reads. PR 41056. [Jean-Frederic Clere, Jim Jagielski] *) apxs: Enhance -q flag to print all known variables and their values when invoked without variable name(s). [William Rowe, Sander Temme] *) mod_dbd: Create memory sub-pools for each DB connection and close DB connections in a pool cleanup function. Ensure prepared statements are destroyed before DB connection is closed. When using reslists, prevent segfaults when child processes exit, and stop memory leakage of ap_dbd_t structures. Avoid use of global s->process->pool, which isn't destroyed by exiting child processes in most multi-process MPMs. PR 39985. [Chris Darroch, Nick Kew] *) 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: Handle error conditions in dbd_construct() properly. Simplify ap_dbd_open() and use correct arguments to apr_dbd_error() when non-threaded. Register correct cleanup data in non-threaded ap_dbd_acquire() and ap_dbd_cacquire(). Clean up configuration data and merge function. Use ap_log_error() wherever possible. [Chris Darroch, Nick Kew] *) core: Do not replace a Date header set by a proxied backend server. PR 40232. [Ruediger Pluem] *) mod_proxy: Ensure that at least scheme://hostname[:port] matches between worker and URL when searching for the best fitting worker for a given URL. PR 40910. [Ruediger Pluem] *) mod_cache: Remove expired content from cache that cannot be revalidated. PR 30370. [Ruediger Pluem] *) 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] *) mod_proxy: Add a missing assignment in an error checking code path. PR 40865. [Andrew Rucker Jones ] *) mod_mem_cache: Increase the minimum and default value for MCacheMinObjectSize from 0 to 1, as a MCacheMinObjectSize of 0 does not make sense and leads to a division by zero. PR 40576. [Xuekun Hu ] *) 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] *) mod_ssl: Fix spurious hostname mismatch warning for valid wildcard certificates. PR 37911. [Nick Burch ] *) 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
