Only used used when amenableparser is passed; the user can now define the page used for {{PAGENAME}} and related stuff instead of being hardcoded to "API"
* MessageCache::singleton() calls wfGetMessageCacheStorage() directly instead of using $messageMemc, just in case this would be called before that variable is set
* Per TimStarling: also removed deprecated methods in MessageCache class: addMessages() and related, [get|set|enable|disable]Transform(), loadAllMessages(), loadMessageFile() and some others. Same for the legacyData stuff in LocalisationCache that was only used by MessageCache::addMessages() and related.
* Converted remaining extensions
to try to load the message text and cache the result individually. However
in the default configuration cache miss always means that the message doesn't
exists in the database.
sed -i 's/$wgContLanguageCode/$wgLanguageCode/g'
These are now the same, always. Per and since r15827.
$wgLanguageCode wins due to being the one set by LocalSettings.
$wgContLanguageCode definition at includes/Setup.php kept for now.
* 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.
