* All manually built LIKE queries in the core are replaced with a wrapper function Database::buildLike()
* This function automatically performs all escaping, so Database::escapeLike() is now almost never used
* In SqlBagOStuff, ignore errors due to a read-only database, per my comments on CR r42796. Same for LocalisationCache.
* Merged SqlBagOStuff and MediaWikiBagOStuff, that proved to be an awkward and unnecessary generalisation. Use the standard quoting wrapper functions instead of $db->query().
* Implemented atomic incr() and decr() functions for SqlBagOStuff.
* Made incr() and decr() generally work roughly the same as it does in memcached, respecting negative steps instead of ignoring such operations. This allows decr() to be implemented in terms of incr().
* Per bug 11533, in MessageCache.php, don't retry 20 times on a cache failure, that's really memcached-specific and won't be useful for other cache types. It's not really very useful for memcached either.
* Moved MySQL-specific implementations of wasDeadlock() and wasErrorReissuable() to DatabaseMysql.
* Briefly tested page views with $wgReadOnly=read_only=1, fixed an error from Article::viewUpdates(). A CentralAuth fix will be in a subsequent commit.
* Made wfDeprecated() issue a notice only once for each function name instead of every time the function is called.
* Added exceptions for malformed keys input to $wgMessageCache->get(), per CR comments on r52503
* Fixed notice from MWException::useMessageCache()
* The serialized message cache, which would have been redundant, has been removed. Similar performance characteristics can be achieved with $wgLocalisationCacheConf['manualRecache'] = true;
* Added a maintenance script rebuildLocalisationCache.php for offline rebuilding of the localisation cache.
* Extension i18n files can now contain any of the variables which can be set in Messages*.php. It is possible, and recommended, to use this feature instead of the hooks for special page aliases and magic words.
* $wgExtensionAliasesFiles, LanguageGetMagic and LanguageGetSpecialPageAliases are retained for backwards compatibility. $wgMessageCache->addMessages() and related functions have been removed. wfLoadExtensionMessages() is a no-op and can continue to be called for b/c.
* Introduced $wgCacheDirectory as a default location for the various local caches that have accumulated. Suggested $IP/cache as a good place for it in the default LocalSettings.php and created this directory with a deny-all .htaccess.
* Patched Exception.php to avoid using the message cache when an exception is thrown from within LocalisationCache, since this tends to fail horribly.
* Removed Language::getLocalisationArray(), Language::loadLocalisation(), Language::load()
* Fixed FileDependency::__sleep()
* In Cdb.php, fixed newlines in debug messages
In MessageCache::get():
* Replaced calls to $wgContLang capitalisation functions with plain PHP functions, reducing the typical case from 99us to 93us. Message cache keys are already documented as being restricted to ASCII.
* Implemented a more efficient way to filter out bogus language codes, reducing the "foo/en" case from 430us to 101us
* Optimised wfRunHooks() in the typical do-nothing case, from ~30us to ~3us. This reduced MessageCache::get() typical case time from 93us to 38us.
* Removed hook MessageNotInMwNs to save an extra 3us per cache hit. Reimplemented the only user (LocalisationUpdate) using the new hook LocalisationCacheRecache.
Previously we only passed on if we were interface or content, but if we're rendering for some third alternative it didn't get used.
Note that parse and parseinline are probably still wrong.... some better model may be required here.
Also it may be wrong in the case of fallbacks ... if you get an English message, is it right to use the Czech magic word parsing?
Hmm.
Might back it out if there's a better way. :)
* Merged replaceFreeExternalLinks() with doMagicLinks(). Makes a lot of sense, very similar operations, doesn't break any parser tests. Stops free links from interacting with other parser stages, the same way ISBN links don't.
* The pass order change fixes Brion's complaint in r39980. Early link expansion, triggered by having more than 1000 links in the page, was outputting URLs which were destroyed by RFEL. Added parser test.
* Fixed an unrelated bug in LinkHolderArray::replace(): if a link to a redirect appears in two separate RLH calls, the second and subsequent calls do not add the mw-redirect class. Caused by an unmigrated LinkCache fetch.
* Added a parser test for a pass interaction bug that the pass order change fixes.
* The fuzzer told me to tell you that free external links in non-caption image parameters, which are and have always been invisible, are now not registered either.
* Miscellaneous supporting updates to the test infrastructure.
* Split link placeholder/replacement handling into a separate object, LinkHolderArray.
* Remove Title objects from LinkCache, they apparently weren't being used at all. Same unconstrained memory usage as the former $parser->mLinkHolders.
* Introduced ExplodeIterator -- a workalike for explode() which doesn't use a significant amount of memory
* Introduced StringUtils::explode() -- select whether to use the simulated or native explode() depending on how many items there are
* Migrated most instances of explode() in Parser.php to StringUtils::explode()
* Renamed some variables in Parser::doBlockLevels()
* In Parser.php: $fname => __METHOD__, Parser => self/__CLASS__, to support Parser_DiffTest more easily
* Doc update in includes/MessageCache.php for r39412
* MW_TITLECACHE_MAX => Title::CACHE_MAX, nicer name, easier to access from another module
* Use wfMkdirParents() instead of mkdir() with a recursive argument.
* Also, allow $wgDirectoryMode take over, instead of hardcoding 0777.
* +formatting
ExtendJSGlobalVars is probably ok in function, though I don't really like its name.
wfMessageCacheReplace seems really unclear as to what it's trying to accomplish.
* removed use of umask, wfMkdirParents works now
* splitting of messages per language is now unconditional
* storing cached messages in 2-d array of code => messages
* fixed a bug in replace(), now deletion works properly
* clear() should actually do something now
* try to delay parser creation in transform()
* removed the use of $memcPrefix and wfMemcKeyLang() in favour of wfMemcKey()
* escape $code in loadFromDb()
* use member variable instead of static variable for tracking loaded languages
Doxygen documentation update:
* Changed alls @addtogroup to @ingroup. @addtogroup adds the comment to the group description, but doesn't add the file, class, function, ... to the group like @ingroup does. See for example http://svn.wikimedia.org/doc/group__SpecialPage.html where it's impossible to see related files, classes, ... that should belong to that group.
* Added @file to file description, it seems that it should be explicitely decalred for file descriptions, otherwise doxygen will think that the comment document the first class, variabled, function, ... that is in that file.
* Removed some empty comments
* Removed some ?>
Added following groups:
* ExternalStorage
* JobQueue
* MaintenanceLanguage
One more thing: there are still a lot of warnings when generating the doc.
