2 Changes with Apache 2.5.0
4 *) mod_auth_digest: Actually use the secret when generating nonces. This change
5 may cause problems if used with round robin load balancers. PR 54637
8 *) mod_cache_socache: Use the name of the socache implementation when performing
9 a lookup rather than using the raw arguments. [Martin Ksellmann
10 <martin@ksellmann.de>]
12 *) rotatelogs: add -n number-of-files option to roate through a number
13 of fixed-name logfiles. [Eric Covener]
15 *) mod_lua: If a LuaMapHandler doesn't return any value, log a warning
16 and treat it as apache2.OK. [Eric Covener]
18 *) ab: Add a new -l parameter in order not to check the length of the responses.
19 This can be usefull with dynamic pages.
20 PR9945, PR27888, PR42040 [<ccikrs1 cranbrook edu>]
22 *) mod_ssl: Fix possible truncation of OCSP responses when reading from the
25 *) mod_session_dbd: Make sure that dirty flag is respected when saving
26 sessions, and ensure the session ID is changed each time the session
27 changes. [Takashi Sato <takashi tks.st>, Graham Leggett]
29 *) mod_dav: Sending a MERGE request against a URI handled by mod_dav_svn with
30 the source href (sent as part of the request body as XML) pointing to a
31 URI that is not configured for DAV will trigger a segfault. [Ben Reser
34 *) mod_logio: new format-specifier %C (combined) which is the sum of received
36 PR54015 [Christophe Jaillet]
38 *) core: Remove apr_brigade_flatten(), buffering and duplicated code
39 from the HTTP_IN filter, parse chunks in a single pass with zero copy.

42 *) mod_deflate: Remove assumptions as to when an EOS bucket might arrive.
43 Gracefully step aside if the body size is zero. [Graham Leggett]
45 *) 'AuthGroupFile' and 'AuthUserFile' do not accept anymore the optional
46 'standard' keyword . It was unused and not documented.
47 PR54463 [Tianyin Xu <tixu cs.ucsd.edu> and Christophe Jaillet]

50 effective by formally overriding origin server behaviour. [Graham
51 Leggett, Co-Advisor <coad measurement-factory.com>]
53 *) core: Stop the HTTP_IN filter from attempting to write error buckets
54 to the output filters, which is bogus in the proxy case. Create a
55 clean mapping from APR codes to HTTP status codes, and use it where
56 needed. [Graham Leggett]
58 *) mod_proxy: Ensure we don't attempt to amend a table we are iterating
59 through, ensuring that all headers listed by Connection are removed.

66 Co-Advisor <coad measurement-factory.com>]
68 *) mod_cache: If a 304 response indicates an entity not currently cached, then
69 the cache MUST disregard the response and repeat the request without the
70 conditional. [Graham Leggett, Co-Advisor <coad measurement-factory.com>]
72 *) mod_proxy: Fix seg-faults when using the global pool on threaded
73 MPMs [Thomas Eckert <thomas.r.w.eckert gmail.com>, Jim Jagielski]

76 504 Gateway Timout as opposed to 502 Bad Gateway, in order to be
77 compliant with RFC2616 14.9.4 Cache Revalidation and Reload Controls.
78 [Graham Leggett, Co-Advisor <coad measurement-factory.com>]
80 *) mod_cache: Ensure that we don't attempt to replace a cached response
81 with an older response as per RFC2616 13.12. [Graham Leggett, Co-Advisor
82 <coad measurement-factory.com>]
84 *) core, mod_cache: Ensure RFC2616 compliance in ap_meets_conditions()
85 with weak validation combined with If-Range and Range headers. Break

87 server. Ensure weak validation RFC compliance in the byteranges filter.
88 Ensure RFC validation compliance when serving cached entities. PR 16142
89 [Graham Leggett, Co-Advisor <coad measurement-factory.com>]
91 *) core: Add the ability to do explicit matching on weak and strong ETags
92 as per RFC2616 Section 13.3.3. [Graham Leggett, Co-Advisor

98 Co-Advisor <coad measurement-factory.com>]
100 *) mod_cache: Honour Cache-Control: no-store in a request. [Graham Leggett]
102 *) mod_cache: RFC2616 14.9.3 The s-maxage directive also implies the

105 *) mod_cache: Make sure that contradictory entity headers present in a 304
106 Not Modified response are caught and cause the entity to be removed.
109 *) mod_cache: Make sure Vary processing handles multivalued Vary headers and
110 multivalued headers referred to via Vary. [Graham Leggett]
112 *) mod_cache: When serving from cache, only the last header of a multivalued
113 header was taken into account. Fixed. [Graham Leggett]
115 *) mod_cache: Ignore response headers specified by no-cache=header and
116 private=header as specified by RFC2616 14.9.1 What is Cacheable. Ensure
117 that these headers are still processed when multiple Cache-Control
118 headers are present in the response. PR 54706 [Graham Leggett,
119 Yann Ylavic <ylavic.dev gmail.com>]
121 *) mod_cache: Invalidate cached entities in response to RFC2616 Section

133 PR 52559 [Diego Santa Cruz <diego.santaCruz spinetix.com>]
135 *) mod_dav: When a PROPPATCH attempts to remove a non-existent dead
136 property on a resource for which there is no dead property in the same
137 namespace httpd segfaults. PR 52559 [Diego Santa Cruz
138 <diego.santaCruz spinetix.com>]
140 *) mod_dav: Ensure URI is correctly uriencoded on return. PR 54611
141 [Timothy Wood <tjw omnigroup.com>]
143 *) mod_dav: Sending a If or If-Match header with an invalid ETag doesn't
144 result in a 412 Precondition Failed. PR 54610 [Timothy Wood
147 *) mod_dav: Make sure that when we prepare an If URL for Etag comparison,
148 we compare unencoded paths. PR 53910 [Timothy Wood <tjw omnigroup.com>]
150 *) core, mod_ssl: Lift the restriction that prevents mod_ssl taking
151 full advantage of the event MPM. Enable the ability for a module

257 rather than throwing an internal server error. [Daniel Gruno]
259 *) mod_lua: Add functions r:flush and r:sendfile as well as additional
260 request information to the request_rec structure. [Daniel Gruno]
262 *) mod_lua: Add a server scope for Lua states, which creates a pool of

294 [Matthew Steele <mdsteele google.com>]
296 *) cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will
