Changes with Apache 2.5.0
*) Fix potential rejection of valid MaxMemFree and ThreadStackSize
directives. [Mike Rumph <mike.rumph oracle.com>]
*) 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 <ylavic dev gmail com>]
*) mod_cgid: Use the servers Timeout for each read from a CGI script,
allow override with new CGIDRequestTimeout directive. PR43494
[Eric Covener, Toshikuni Fukaya <toshikuni-fukaya cybozu co jp>]
*) 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
<blaise tarr gmail com>]
*) mod_authn_socache: Support optional initialization arguments for
socache providers. [Chris Darroch]
*) mod_session: Reset the max-age on session save. PR 47476. [Alexey
Varlamov <alexey.v.varlamov gmail com>]
*) mod_session: After parsing the value of the header specified by the
SessionHeader directive, remove the value from the response. PR 55279.
[Graham Leggett]
*) mod_auth_form: Make sure the optional functions are loaded even when
the AuthFormProvider isn't specified. [Graham Leggett]
*) mod_ssl: Improve handling of ephemeral DH and ECDH keys by
allowing custom parameters to be configured via SSLCertificateFile,
and by adding standardized DH parameters for 1024/2048/3072/4096 bits.
Unless custom parameters are configured, the standardized parameters
are applied based on the certificate's RSA/DSA key size. [Kaspar Brand]
*) mod_ssl, configure: Require OpenSSL 0.9.8a or later. [Kaspar Brand]
*) 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_ssl: drop support for export-grade ciphers with ephemeral RSA
keys, and unconditionally disable aNULL, eNULL and EXP ciphers
(not overridable via SSLCipherSuite). [Kaspar Brand]
*) 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]
*) mod_proxy_fcgi: Handle reading protocol data that is split between
packets. [Jeff Trawick]
*) mod_proxy_fcgi: Remove 64K limit on encoded length of all envvars.
An individual envvar with an encoded length of more than 16K will be
omitted. [Jeff Trawick]
*) core: draft-ietf-httpbis-p1-messaging-23 corrections regarding
TE/CL conflicts. [Yann Ylavic <ylavic.dev gmail com>, 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_cache: Avoid a crash with strcmp() when the hostname is not provided.
[Graham Leggett]
*) mod_lua: Add rudimentary support for WebSocket interaction. This is
currently request-bound and only supports the WS protocol. [Daniel Gruno]
*) mod_lua: Add getcookie/setcookie for reading/writing HTTP cookies
[Daniel Gruno]
*) 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 <berni birkenwald de>]
*) 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 Covnener]
*) 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 util_fcgi.h and associated definitions and support
routines for FastCGI, based largely on mod_proxy_fcgi.
[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 <jkaluza redhat.com>]
*) 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 <jelaas gmail.com>]
*) 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 <basant.kukreja sun.com>, 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]
*) mod_ssl: Add support for OpenSSL configuration commands [Stephen Henson]
*) 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 <If> LogLevel ... </If> 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 <jkaluza redhat.com>]
*) 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 <mdsteele google.com>]
*) 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. [Graham Leggett]
*) mod_noloris
*) APREQ
*) Simple MPM
*) mod_serf
