98N/A -*- coding: utf-8 -*-
98N/AChanges with Apache 2.5.0
98N/A *) core: Replace pre_htaccess hook with more flexible open_htaccess hook.
98N/A *) mod_authnz_ldap: Support primitive LDAP servers that do not accept
98N/A filters, such as "SDBM-backed LDAP" on
z/OS, by allowing a special
98N/A filter "none" to be specified in AuthLDAPURL. [Eric Covener]
98N/A *) mod_file_cache: mod_file_cache should be able to serve files that
98N/A haven't had a Content-Type set via
e.g. mod_mime. [Eric Covener]
98N/A *) core: merge AllowEncodedSlashes from the base configuration into
98N/A virtual hosts. [Eric Covener]
98N/A *) mod_headers: Add 'setifempty' command to Header and RequestHeader.
98N/A *) mod_ldap: Retry transient LDAP connection errors when they occur
98N/A during the authorization stage.
98N/A *) mod_ldap: Don't keep retrying if a new LDAP connection times out.
98N/A *) mod_deflate: permit compilation of mod_deflate against a zlib that has
98N/A been configured with -D Z_PREFIX, which redefines the token "deflate".
98N/A *) mod_auth_digest: Use the secret when generating nonces in all cases and
98N/A not only when AuthName is used in .htaccess files (this change may cause
98N/A problems if used with round robin load balancers). Don't regenerate the
98N/A secret on graceful restarts. PR 54637 [Stefan Fritsch]
98N/A *) ab: Add a new -l parameter in order not to check the length of the responses.
98N/A This can be usefull with dynamic pages.
98N/A PR9945, PR27888, PR42040 [<ccikrs1 cranbrook edu>]
98N/A *) mod_ssl: Fix possible truncation of OCSP responses when reading from the
98N/A server. [Joe Orton]
98N/A *) mod_session_dbd: Make sure that dirty flag is respected when saving
98N/A sessions, and ensure the session ID is changed each time the session
98N/A changes. [Takashi Sato <takashi
tks.st>, Graham Leggett]
98N/A *) mod_logio: new format-specifier %C (combined) which is the sum of received
98N/A and sent byte counts.
98N/A PR54015 [Christophe Jaillet]
98N/A *) core: Remove apr_brigade_flatten(), buffering and duplicated code
98N/A from the HTTP_IN filter, parse chunks in a single pass with zero copy.
98N/A Reduce memory usage by 48 bytes per request. [Graham Leggett]
98N/A *) mod_deflate: Remove assumptions as to when an EOS bucket might arrive.
98N/A Gracefully step aside if the body size is zero. [Graham Leggett]
98N/A *) mod_proxy_http: Make the proxy-interim-response environment variable
98N/A effective by formally overriding origin server behaviour. [Graham
98N/A *) core: Stop the HTTP_IN filter from attempting to write error buckets
98N/A to the output filters, which is bogus in the proxy case. Create a
98N/A clean mapping from APR codes to HTTP status codes, and use it where
98N/A needed. [Graham Leggett]
98N/A *) mod_proxy: Ensure we don't attempt to amend a table we are iterating
98N/A through, ensuring that all headers listed by Connection are removed.
*) mod_proxy: Fix seg-faults when using the global pool on threaded
*) 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
*) core, mod_ssl: Lift the restriction that prevents mod_ssl taking
full advantage of the event MPM. Enable the ability for a module
to reverse the sense of a poll event from a read to a write or vice
*) 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"
*) 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.
*) http: Remove support for Request-Range header sent by Navigator 2-3 and
*) 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]
*) mpm_event: Check that AsyncRequestWorkerFactor is not negative. PR 54254.
[Jackie Zhang <jackie qq zhang gmail com>]
*) mod_ssl: Add support for OpenSSL configuration commands [Stephen Henson]
*) 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.
*) 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.
*) core: Add dirwalk_stat and pre_htaccess hooks, allowing mpm-itk
to be used without patches to httpd core. [Jeff Trawick]
*) 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]
*) mod_ssl: Catch missing or mismatched client
cert/key pairs with
- APIs: ap_log_pid(), ap_remove_pid, ap_read_pid()
- core: the scoreboard (ScoreBoardFile), pid file (PidFile), and
- 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
*) suexec: Add --enable-suexec-capabilites support on Linux, to use
*) suexec: Add support for logging to syslog as an alternative to logging
to a file; configure --without-suexec-logfile --with-suexec-syslog.
*) mod_ssl: Add support for TLS Next Protocol Negotiation. PR 52210.
*) 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]

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]
