2 Changes with Apache 2.5.0
4 *) mod_authnz_ldap: Support primitive LDAP servers that do not accept
5 filters, such as "SDBM-backed LDAP" on z/OS, by allowing a special
6 filter "none" to be specified in AuthLDAPURL. [Eric Covener]
8 *) mod_file_cache: mod_file_cache should be able to serve files that
9 haven't had a Content-Type set via e.g. mod_mime. [Eric Covener]
11 *) core: merge AllowEncodedSlashes from the base configuration into
12 virtual hosts. [Eric Covener]
14 *) mod_headers: Add 'setifempty' command to Header and RequestHeader.
17 *) AIX: Install DSO's with "cp" instead of "install" in instdso.sh
20 *) mod_ldap: Retry transient LDAP connection errors when they occur
21 during the authorization stage.
24 *) mod_ldap: Don't keep retrying if a new LDAP connection times out.
27 *) mod_deflate: permit compilation of mod_deflate against a zlib that has
28 been configured with -D Z_PREFIX, which redefines the token "deflate".
31 *) mod_socache_shmcb.c: Remove arbitrary restriction on shared memory size
32 previously limited to 64MB. [Jens Låås <jelaas gmail.com>]
34 *) mod_auth_digest: Use the secret when generating nonces in all cases and
35 not only when AuthName is used in .htaccess files (this change may cause
36 problems if used with round robin load balancers). Don't regenerate the
37 secret on graceful restarts. PR 54637 [Stefan Fritsch]
39 *) ab: Add a new -l parameter in order not to check the length of the responses.
40 This can be usefull with dynamic pages.
41 PR9945, PR27888, PR42040 [<ccikrs1 cranbrook edu>]
43 *) mod_ssl: Fix possible truncation of OCSP responses when reading from the
46 *) mod_session_dbd: Make sure that dirty flag is respected when saving
47 sessions, and ensure the session ID is changed each time the session
48 changes. [Takashi Sato <takashi tks.st>, Graham Leggett]
50 *) mod_logio: new format-specifier %C (combined) which is the sum of received
52 PR54015 [Christophe Jaillet]
54 *) core: Remove apr_brigade_flatten(), buffering and duplicated code
55 from the HTTP_IN filter, parse chunks in a single pass with zero copy.
56 Reduce memory usage by 48 bytes per request. [Graham Leggett]
58 *) mod_deflate: Remove assumptions as to when an EOS bucket might arrive.
59 Gracefully step aside if the body size is zero. [Graham Leggett]
61 *) mod_proxy_http: Make the proxy-interim-response environment variable
62 effective by formally overriding origin server behaviour. [Graham
63 Leggett, Co-Advisor <coad measurement-factory.com>]
65 *) core: Stop the HTTP_IN filter from attempting to write error buckets
66 to the output filters, which is bogus in the proxy case. Create a
67 clean mapping from APR codes to HTTP status codes, and use it where
68 needed. [Graham Leggett]
70 *) mod_proxy: Ensure we don't attempt to amend a table we are iterating
71 through, ensuring that all headers listed by Connection are removed.
72 [Graham Leggett, Co-Advisor <coad measurement-factory.com>]
74 *) mod_proxy: Fix seg-faults when using the global pool on threaded
75 MPMs [Thomas Eckert <thomas.r.w.eckert gmail.com>, Jim Jagielski]
77 *) mod_proxy: Ensure network errors detected by the proxy are returned as
78 504 Gateway Timout as opposed to 502 Bad Gateway, in order to be
79 compliant with RFC2616 14.9.4 Cache Revalidation and Reload Controls.
81 *) mod_dav: mod_dav overrides dav_fs response on PUT failure. PR 35981
82 [Basant Kumar Kukreja <basant.kukreja sun.com>, Alejandro Alvarez
83 <alejandro.alvarez.ayllon cern.ch>]
85 *) core, mod_ssl: Lift the restriction that prevents mod_ssl taking
86 full advantage of the event MPM. Enable the ability for a module
87 to reverse the sense of a poll event from a read to a write or vice
88 versa. [Graham Leggett]
90 *) mod_ldap: LDAP connections used for authentication were not respecting
91 LDAPConnectionPoolTimeout. PR 54587
93 *) core: ap_rgetline_core now pulls from r->proto_input_filters.
95 *) mod_proxy_html: process parsed comments immediately.
96 Fixes bug where parsed comments may be lost. [Nick Kew]
98 *) mod_proxy_html: introduce doctype for HTML 5 [Nick Kew]
100 *) mod_proxy_html: fix typo-bug processing "strict" vs "transitional"
101 HTML/XHTML [Nick Kew]
103 *) core: Add option to add valgrind support. Use it to reduce false positive
104 warnings in mod_ssl. [Stefan Fritsch]
106 *) mod_authn_file, mod_authn_dbd, mod_authn_dbm, mod_authn_socache:
107 Cache the result of the most recent password hash verification for every
108 keep-alive connection. This saves some expensive calculations.
111 *) http: Remove support for Request-Range header sent by Navigator 2-3 and
112 MSIE 3. [Stefan Fritsch]
114 *) core, http: Extend HttpProtocol with an option to enforce stricter HTTP
115 conformance or to only log the found problems. [Stefan Fritsch]
117 *) core: Correctly parse an IPv6 literal host specification in an absolute
118 URL in the request line. [Stefan Fritsch]
120 *) mpm_event: Check that AsyncRequestWorkerFactor is not negative. PR 54254.
121 [Jackie Zhang <jackie qq zhang gmail com>]
123 *) mod_ssl: Add support for OpenSSL configuration commands [Stephen Henson]
127 *) core: Add LogLevelOverride directive that allows to override the
128 loglevel for clients from certain IPs. This also works for things
129 like the SSL handshake where <If> LogLevel ... </If> is evaluated
130 too late. [Stefan Fritsch]
132 *) core: Add new directive Warning to issue warnings from a configuration
133 file. Both Warning and Error now generate a timestamped log message.
136 *) ap_expr: Add SERVER_PROTOCOL_VERSION, ..._MAJOR, and ..._MINOR
137 variables. [Stefan Fritsch]
139 *) core: New directive RegisterHttpMethod for registering non-standard
140 HTTP methods. [Stefan Fritsch]
142 *) core: New directive HttpProtocol which allows to disable HTTP/0.9
143 support. [Stefan Fritsch]
145 *) mod_allowhandlers: New module to forbid specific handlers for specific
146 directories. [Stefan Fritsch]
148 *) mod_systemd: New module, for integration with systemd on Linux.
149 [Jan Kaluza <jkaluza redhat.com>]
151 *) core: Add dirwalk_stat and pre_htaccess hooks, allowing mpm-itk
152 to be used without patches to httpd core. [Jeff Trawick]
154 *) WinNT MPM: Store pid and generation for each thread in scoreboard
155 to allow tracking of threads from exiting children via mod_status
156 or other such mechanisms. [Jeff Trawick]
158 *) mod_ssl: Catch missing or mismatched client cert/key pairs with
159 SSLProxyMachineCertificateFile/Path directives. PR 52212.
160 [Keith Burdis <keith burdis.org>, Joe Orton]
162 *) The following now respect DefaultRuntimeDir/DEFAULT_REL_RUNTIMEDIR:
163 - APIs: ap_log_pid(), ap_remove_pid, ap_read_pid()
164 - core: the scoreboard (ScoreBoardFile), pid file (PidFile), and
166 - mod_cache: thundering herd lock directory
167 - mod_lbmethod_heartbeat, mod_heartmonitor: heartbeat storage file
168 - mod_ldap: shared memory cache
169 - mod_socache_shmcb, mod_socache_dbm: shared memory or dbm for cache
172 *) suexec: Add --enable-suexec-capabilites support on Linux, to use
173 setuid/setgid capability bits rather than a setuid root binary.
176 *) suexec: Add support for logging to syslog as an alternative to logging
177 to a file; configure --without-suexec-logfile --with-suexec-syslog.
180 *) mod_ssl: Add support for TLS Next Protocol Negotiation. PR 52210.
181 [Matthew Steele <mdsteele google.com>]
183 *) cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will
184 be compiled by the build compiler instead of the host compiler.
185 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.
186 PR 51257. [Guenter Knauf]
188 *) core: In maintainer mode, replace apr_palloc with a version that
189 initializes the allocated memory with non-zero values, except if
190 AP_DEBUG_NO_ALLOC_POISON is defined. [Stefan Fritsch]
192 *) mod_policy: Add a new testing module to help server administrators
193 enforce a configurable level of protocol compliance on their
194 servers and application servers behind theirs. [Graham Leggett]
196 *) mod_firehose: Add a new debugging module able to record traffic
197 passing through the server in such a way that connections and/or
198 requests be reconstructed and replayed. [Graham Leggett]
