-*- coding: utf-8 -*- Changes with Apache 2.5.0 *) mod_dir: Don't search for a DirectoryIndex or DirectorySlash on a URL that was just rewritten by mod_rewrite. PR53929. [Eric Covener] *) mod_dir: Add DirectoryCheckHandler to allow a 2.2-like behavior, skipping execution when a handler is already set. PR53929. [Eric Covener] *) mod_rewrite: Protect against looping with the [N] flag by enforcing a default limit of 10000 iterations, and allowing each rule to change its limit. [Eric Covener] *) mod_ssl: Fix config merging of SSLOCSPEnable and SSLOCSPOverrideResponder. [Jeff Trawick] *) Add HttpContentLengthHeadZero and HttpExpectStrict directives. [Yehuda Sadeh , Justin Erenkrantz] *) core: Support named groups and backreferences within the LocationMatch, DirectoryMatch, FilesMatch and ProxyMatch directives. [Graham Leggett] *) mod_ssl: Remove the hardcoded algorithm-type dependency for the SSLCertificateFile and SSLCertificateKeyFile directives, to enable future algorithm agility, and deprecate the SSLCertificateChainFile directive (obsoleted by SSLCertificateFile). [Kaspar Brand] *) FreeBSD: Disable IPv4-mapped listening sockets by default for versions 5+ instead of just for FreeBSD 5. PR 53824. [Jeff Trawick] *) mod_auth_form: Add a debug message when the fields on a form are not recognised. [Graham Leggett] *) mod_ssl: Add -t -DDUMP_CA_CERTS option which dumps the filenames of all configured SSL CA certificates to stdout the same way as DUMP_CERTS does. [Jan Kaluza] *) mod_headers: Allow the "value" parameter of Header and RequestHeader to contain an ap_expr expression if prefixed with "expr=". [Eric Covener] *) Add suspend_connection and resume_connection hooks to notify modules when the thread/connection relationship changes. (Currently implemented only for the Event MPM; should be implemented for all async MPMs.) [Jeff Trawick] *) mod_ssl: Don't flush when an EOS is received. Prepares mod_ssl to support write completion. [Graham Leggett] *) prefork: Fix long delays when doing a graceful restart. PR 54852 [Jim Jagielski, Arkadiusz Miskiewicz ] *) core: Add parse_errorlog_arg callback to ap_errorlog_provider to allow providers to check the ErrorLog argument. [Jan Kaluza] *) core: Detect incomplete body in HTTP input filter and return APR_INCOMPLETE. PR 55475 [Yann Ylavic ] *) mod_cgid: Use the servers Timeout for each read from a CGI script, allow override with new CGIDRequestTimeout directive. PR43494 [Eric Covener, Toshikuni Fukaya ] *) core: Add missing Reason-Phrase in HTTP response headers. PR 54946. [Rainer Jung] *) core: ensure any abnormal exit is reported to stderr if it's a tty. PR 55670 [Nick Kew] *) mod_proxy: Added support for unix domain sockets as the backend server endpoint [Jim Jagielski, Blaise Tarr ] *) mod_auth_form: Make sure the optional functions are loaded even when the AuthFormProvider isn't specified. [Graham Leggett] *) mod_lua: Let the Inter-VM get/set functions work with a global shared memory pool instead of a per-process pool. [Daniel Gruno] *) ldap: Support ldaps when using the Microsoft LDAP SDK. PR 54626. [Jean-Frederic Clere] *) mod_proxy: Add ap_connection_reusable() for checking if a connection is reusable as of this point in processing. [Jeff Trawick] *) mod_authnz_ldap: Change default value of AuthLDAPMaxSubGroupDepth to 0 to avoid performance problems when subgroups aren't in use. [Eric Covener] *) mod_syslog: New module implementing syslog ap_error_log provider. Previously, this code was part of core, now it's in separate module. [Jan Kaluza] *) core: Add ap_errorlog_provider to make ErrorLog logging modular. Move syslog support from core to new mod_syslog. [Jan Kaluza] *) core: draft-ietf-httpbis-p1-messaging-23 corrections regarding TE/CL conflicts. [Yann Ylavic , Jim Jagielski] *) mod_proxy_fcgi: Use apr_socket_timeout_get instead of hard-coded 30 seconds timeout. [Jan Kaluza] *) WinNT MPM: If ap_run_pre_connection() fails or sets c->aborted, don't save the socket for reuse by the next worker as if it were an APR_SO_DISCONNECTED socket. Restores 2.2 behavior. [Eric Covener] *) mod_lua: Add a logging hook for modifying/skipping logs. [Daniel Gruno] *) mod_status, mod_echo: Fix the display of client addresses. They were truncated to 31 characters which is not enough for IPv6 addresses. PR 54848 [Bernhard Schmidt ] *) mod_lua: If the first yield() of a LuaOutputFilter returns a string, it should be prefixed to the response as documented. [Eric Covener] *) mod_lua: Remove ETAG, Content-Length, and Content-MD5 when a LuaOutputFilter is configured without mod_filter. [Eric Covener] *) mod_lua: Register LuaOutputFilter scripts as changing the content and content-length by default, when run my mod_filter. Previously, growing or shrinking a response that started with Content-Length set would require mod_filter and FilterProtocol change=yes. [Eric Covener] *) mod_lua: Return a 500 error if a LuaHook* script doesn't return a numeric return code. [Eric Covener] *) mod_authnz_fcgi: New module to enable FastCGI authorizer applications to authenticate and/or authorize clients. [Jeff Trawick] *) core: Add ap_log_data(), ap_log_rdata(), etc. for logging buffers. [Jeff Trawick] *) mod_unique_id: Use output of the PRNG rather than IP address and pid, avoiding sleep() call and possible DNS issues at startup, plus improving randomness for IPv6-only hosts. [Jan Kaluza ] *) mod_authnz_ldap: Support primitive LDAP servers that do not accept filters, such as "SDBM-backed LDAP" on z/OS, by allowing a special filter "none" to be specified in AuthLDAPURL. [Eric Covener] *) mod_file_cache: mod_file_cache should be able to serve files that haven't had a Content-Type set via e.g. mod_mime. [Eric Covener] *) core: merge AllowEncodedSlashes from the base configuration into virtual hosts. [Eric Covener] *) AIX: Install DSO's with "cp" instead of "install" in instdso.sh [Eric Covener] *) mod_ldap: Don't keep retrying if a new LDAP connection times out. [Eric Covener] *) mod_deflate: permit compilation of mod_deflate against a zlib that has been configured with -D Z_PREFIX, which redefines the token "deflate". [Eric Covener] *) mod_socache_shmcb.c: Remove arbitrary restriction on shared memory size previously limited to 64MB. [Jens Låås ] *) mod_auth_digest: Use the secret when generating nonces in all cases and not only when AuthName is used in .htaccess files (this change may cause problems if used with round robin load balancers). Don't regenerate the secret on graceful restarts. PR 54637 [Stefan Fritsch] *) core: Remove apr_brigade_flatten(), buffering and duplicated code from the HTTP_IN filter, parse chunks in a single pass with zero copy. Reduce memory usage by 48 bytes per request. [Graham Leggett] *) core: Stop the HTTP_IN filter from attempting to write error buckets to the output filters, which is bogus in the proxy case. Create a clean mapping from APR codes to HTTP status codes, and use it where needed. [Graham Leggett] *) mod_proxy: Ensure network errors detected by the proxy are returned as 504 Gateway Timout as opposed to 502 Bad Gateway, in order to be compliant with RFC2616 14.9.4 Cache Revalidation and Reload Controls. *) mod_dav: mod_dav overrides dav_fs response on PUT failure. PR 35981 [Basant Kumar Kukreja , Alejandro Alvarez ] *) core, mod_ssl: Enable the ability for a module to reverse the sense of a poll event from a read to a write or vice versa. This is a step on the way to allow mod_ssl taking full advantage of the event MPM. [Graham Leggett] *) mod_ldap: LDAP connections used for authentication were not respecting LDAPConnectionPoolTimeout. PR 54587 *) core: ap_rgetline_core now pulls from r->proto_input_filters. *) mod_proxy_html: process parsed comments immediately. Fixes bug where parsed comments may be lost. [Nick Kew] *) mod_proxy_html: introduce doctype for HTML 5 [Nick Kew] *) mod_proxy_html: fix typo-bug processing "strict" vs "transitional" HTML/XHTML [Nick Kew] *) core: Add option to add valgrind support. Use it to reduce false positive warnings in mod_ssl. [Stefan Fritsch] *) mod_authn_file, mod_authn_dbd, mod_authn_dbm, mod_authn_socache: Cache the result of the most recent password hash verification for every keep-alive connection. This saves some expensive calculations. [Stefan Fritsch] *) http: Remove support for Request-Range header sent by Navigator 2-3 and MSIE 3. [Stefan Fritsch] *) core, http: Extend HttpProtocol with an option to enforce stricter HTTP conformance or to only log the found problems. [Stefan Fritsch] *) core: Correctly parse an IPv6 literal host specification in an absolute URL in the request line. [Stefan Fritsch] *) EventOpt MPM *) core: Add LogLevelOverride directive that allows to override the loglevel for clients from certain IPs. This also works for things like the SSL handshake where LogLevel ... is evaluated too late. [Stefan Fritsch] *) core: Add new directive Warning to issue warnings from a configuration file. Both Warning and Error now generate a timestamped log message. [Fabien Coelho] *) ap_expr: Add SERVER_PROTOCOL_VERSION, ..._MAJOR, and ..._MINOR variables. [Stefan Fritsch] *) core: New directive RegisterHttpMethod for registering non-standard HTTP methods. [Stefan Fritsch] *) core: New directive HttpProtocol which allows to disable HTTP/0.9 support. [Stefan Fritsch] *) mod_allowhandlers: New module to forbid specific handlers for specific directories. [Stefan Fritsch] *) mod_systemd: New module, for integration with systemd on Linux. [Jan Kaluza ] *) WinNT MPM: Store pid and generation for each thread in scoreboard to allow tracking of threads from exiting children via mod_status or other such mechanisms. [Jeff Trawick] *) The following now respect DefaultRuntimeDir/DEFAULT_REL_RUNTIMEDIR: - APIs: ap_log_pid(), ap_remove_pid, ap_read_pid() - core: the scoreboard (ScoreBoardFile), pid file (PidFile), and mutexes (Mutex) - mod_cache: thundering herd lock directory - mod_lbmethod_heartbeat, mod_heartmonitor: heartbeat storage file - mod_ldap: shared memory cache - mod_socache_shmcb, mod_socache_dbm: shared memory or dbm for cache [Jeff Trawick] *) suexec: Add --enable-suexec-capabilites support on Linux, to use setuid/setgid capability bits rather than a setuid root binary. [Joe Orton] *) suexec: Add support for logging to syslog as an alternative to logging to a file; configure --without-suexec-logfile --with-suexec-syslog. [Joe Orton] *) mod_ssl: Add support for TLS Next Protocol Negotiation. PR 52210. [Matthew Steele ] *) cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will be compiled by the build compiler instead of the host compiler. Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected. PR 51257. [Guenter Knauf] *) core: In maintainer mode, replace apr_palloc with a version that initializes the allocated memory with non-zero values, except if AP_DEBUG_NO_ALLOC_POISON is defined. [Stefan Fritsch] *) mod_policy: Add a new testing module to help server administrators enforce a configurable level of protocol compliance on their servers and application servers behind theirs. [Graham Leggett] *) mod_firehose: Add a new debugging module able to record traffic passing through the server in such a way that connections and/or requests be reconstructed and replayed.
