2 Changes with Apache 2.5.0
4 *) mod_lua: Remove ETAG, Content-Length, and Content-MD5 when a LuaOutputFilter
5 is configured without mod_filter. [Eric Covener]
7 *) mod_lua: Register LuaOutputFilter scripts as changing the content and
8 content-length by default, when run my mod_filter. Previously,
9 growing or shrinking a response that started with Content-Length set
10 would require mod_filter and FilterProtocol change=yes.
12 *) mod_filter: Add "change=no" as a proto-flag to FilterProtocol
13 to remove a providers initial flags set at registration time.
16 *) mod_lua: Return a 500 error if a LuaHook* script doesn't return a
17 numeric return code. [Eric Covener]
19 *) Add experimental cmake-based build system for Windows. [Jeff Trawick,
22 *) mod_ldap: Change "LDAPReferrals off" to actually set the underlying LDAP
23 SDK option to OFF, and introduce "LDAPReferrals default" to take the SDK
24 default, sans rebind authentication callback.
25 [Jan Kaluza <jkaluza AT redhat.com>]
27 *) mod_authz_groupfile, mod_authz_user: Reduce severity of AH01671 and AH01663
28 from ERROR to DEBUG, since these modules do not know what mod_authz_core
29 is doing with their AUTHZ_DENIED return value. [Eric Covener]
31 *) mod_authnz_fcgi: New module to enable FastCGI authorizer
32 applications to authenticate and/or authorize clients.
35 *) mod_auth_basic: Add AuthBasicUseDigestAlgorithm directive to
36 allow migration of passwords from digest to basic authentication.
39 *) core: Add util_fcgi.h and associated definitions and support
40 routines for FastCGI, based largely on mod_proxy_fcgi.
43 *) core: Add ap_log_data(), ap_log_rdata(), etc. for logging buffers.
46 *) mod_unique_id: Use output of the PRNG rather than IP address and
47 pid, avoiding sleep() call and possible DNS issues at startup,
48 plus improving randomness for IPv6-only hosts.
49 [Jan Kaluza <jkaluza redhat.com>]
51 *) core: Log a message at TRACE1 when the client aborts a connection.
54 *) mod_authnz_ldap: Support primitive LDAP servers that do not accept
55 filters, such as "SDBM-backed LDAP" on z/OS, by allowing a special
56 filter "none" to be specified in AuthLDAPURL. [Eric Covener]
58 *) mod_file_cache: mod_file_cache should be able to serve files that
59 haven't had a Content-Type set via e.g. mod_mime. [Eric Covener]
61 *) core: merge AllowEncodedSlashes from the base configuration into
62 virtual hosts. [Eric Covener]
64 *) mod_headers: Add 'setifempty' command to Header and RequestHeader.
67 *) AIX: Install DSO's with "cp" instead of "install" in instdso.sh
70 *) mod_ldap: Retry transient LDAP connection errors when they occur
71 during the authorization stage.
74 *) mod_ldap: Don't keep retrying if a new LDAP connection times out.
77 *) mod_deflate: permit compilation of mod_deflate against a zlib that has
78 been configured with -D Z_PREFIX, which redefines the token "deflate".
81 *) mod_socache_shmcb.c: Remove arbitrary restriction on shared memory size
82 previously limited to 64MB. [Jens Låås <jelaas gmail.com>]
84 *) mod_auth_digest: Use the secret when generating nonces in all cases and
85 not only when AuthName is used in .htaccess files (this change may cause
86 problems if used with round robin load balancers). Don't regenerate the
87 secret on graceful restarts. PR 54637 [Stefan Fritsch]
89 *) ab: Add a new -l parameter in order not to check the length of the responses.
90 This can be usefull with dynamic pages.
91 PR9945, PR27888, PR42040 [<ccikrs1 cranbrook edu>]
93 *) mod_logio: new format-specifier %C (combined) which is the sum of received
95 PR54015 [Christophe Jaillet]
97 *) core: Remove apr_brigade_flatten(), buffering and duplicated code
98 from the HTTP_IN filter, parse chunks in a single pass with zero copy.
99 Reduce memory usage by 48 bytes per request. [Graham Leggett]
101 *) core: Stop the HTTP_IN filter from attempting to write error buckets
102 to the output filters, which is bogus in the proxy case. Create a
103 clean mapping from APR codes to HTTP status codes, and use it where
104 needed. [Graham Leggett]
106 *) mod_proxy: Ensure network errors detected by the proxy are returned as
107 504 Gateway Timout as opposed to 502 Bad Gateway, in order to be
108 compliant with RFC2616 14.9.4 Cache Revalidation and Reload Controls.
110 *) mod_dav: mod_dav overrides dav_fs response on PUT failure. PR 35981
111 [Basant Kumar Kukreja <basant.kukreja sun.com>, Alejandro Alvarez
112 <alejandro.alvarez.ayllon cern.ch>]
114 *) core, mod_ssl: Enable the ability for a module to reverse the sense of
115 a poll event from a read to a write or vice versa. This is a step on
116 the way to allow mod_ssl taking full advantage of the event MPM.
119 *) mod_ldap: LDAP connections used for authentication were not respecting
120 LDAPConnectionPoolTimeout. PR 54587
122 *) core: ap_rgetline_core now pulls from r->proto_input_filters.
124 *) mod_proxy_html: process parsed comments immediately.
125 Fixes bug where parsed comments may be lost. [Nick Kew]
127 *) mod_proxy_html: introduce doctype for HTML 5 [Nick Kew]
129 *) mod_proxy_html: fix typo-bug processing "strict" vs "transitional"
130 HTML/XHTML [Nick Kew]
132 *) core: Add option to add valgrind support. Use it to reduce false positive
133 warnings in mod_ssl. [Stefan Fritsch]
135 *) mod_authn_file, mod_authn_dbd, mod_authn_dbm, mod_authn_socache:
136 Cache the result of the most recent password hash verification for every
137 keep-alive connection. This saves some expensive calculations.
140 *) http: Remove support for Request-Range header sent by Navigator 2-3 and
141 MSIE 3. [Stefan Fritsch]
143 *) core, http: Extend HttpProtocol with an option to enforce stricter HTTP
144 conformance or to only log the found problems. [Stefan Fritsch]
146 *) core: Correctly parse an IPv6 literal host specification in an absolute
147 URL in the request line. [Stefan Fritsch]
149 *) mod_ssl: Add support for OpenSSL configuration commands [Stephen Henson]
153 *) core: Add LogLevelOverride directive that allows to override the
154 loglevel for clients from certain IPs. This also works for things
155 like the SSL handshake where <If> LogLevel ... </If> is evaluated
156 too late. [Stefan Fritsch]
158 *) core: Add new directive Warning to issue warnings from a configuration
159 file. Both Warning and Error now generate a timestamped log message.
162 *) ap_expr: Add SERVER_PROTOCOL_VERSION, ..._MAJOR, and ..._MINOR
163 variables. [Stefan Fritsch]
165 *) core: New directive RegisterHttpMethod for registering non-standard
166 HTTP methods. [Stefan Fritsch]
168 *) core: New directive HttpProtocol which allows to disable HTTP/0.9
169 support. [Stefan Fritsch]
171 *) mod_allowhandlers: New module to forbid specific handlers for specific
172 directories. [Stefan Fritsch]
174 *) mod_systemd: New module, for integration with systemd on Linux.
175 [Jan Kaluza <jkaluza redhat.com>]
177 *) WinNT MPM: Store pid and generation for each thread in scoreboard
178 to allow tracking of threads from exiting children via mod_status
179 or other such mechanisms. [Jeff Trawick]
181 *) mod_ssl: Catch missing or mismatched client cert/key pairs with
182 SSLProxyMachineCertificateFile/Path directives. PR 52212.
183 [Keith Burdis <keith burdis.org>, Joe Orton]
185 *) The following now respect DefaultRuntimeDir/DEFAULT_REL_RUNTIMEDIR:
186 - APIs: ap_log_pid(), ap_remove_pid, ap_read_pid()
187 - core: the scoreboard (ScoreBoardFile), pid file (PidFile), and
189 - mod_cache: thundering herd lock directory
190 - mod_lbmethod_heartbeat, mod_heartmonitor: heartbeat storage file
191 - mod_ldap: shared memory cache
192 - mod_socache_shmcb, mod_socache_dbm: shared memory or dbm for cache
195 *) suexec: Add --enable-suexec-capabilites support on Linux, to use
196 setuid/setgid capability bits rather than a setuid root binary.
199 *) suexec: Add support for logging to syslog as an alternative to logging
200 to a file; configure --without-suexec-logfile --with-suexec-syslog.
203 *) mod_ssl: Add support for TLS Next Protocol Negotiation. PR 52210.
204 [Matthew Steele <mdsteele google.com>]
206 *) cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will
207 be compiled by the build compiler instead of the host compiler.
208 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.
209 PR 51257. [Guenter Knauf]
211 *) core: In maintainer mode, replace apr_palloc with a version that
212 initializes the allocated memory with non-zero values, except if
213 AP_DEBUG_NO_ALLOC_POISON is defined. [Stefan Fritsch]
215 *) mod_policy: Add a new testing module to help server administrators
216 enforce a configurable level of protocol compliance on their
217 servers and application servers behind theirs. [Graham Leggett]
219 *) mod_firehose: Add a new debugging module able to record traffic
220 passing through the server in such a way that connections and/or
221 requests be reconstructed and replayed. [Graham Leggett]
