* Clean up the ugly adding-then-removing-then-readding HTML <head> and <body> tags in DBConnectionError, deprecates MWException::htmlBodyOnly()
* Also deprecates MWException::htmlHeader(), removes code duplication since MWException::reportHTML() can safely call wfDie() and get an output format appropriate for the entry point
* Copy a couple of HTML headers (Cache-control, Pragma and Content-type) to the wfDie() implementation.
* Fix parsing of the three major entry points (index.php, api.php, load.php) back to PHP 4.4.9. We don't care what happens if you actually try to run these files on old versions, but the entry files need to parse correctly.
* consign /includes/templates/PHP4.php and /includes/templates/NoLocalSettings.php to the fiery pit of hell where they belong.
* Prevent loading of any other files for PHP < 5. WebStart.php was rendered unparseable in PHP 4 by the introduction of try/catch blocks in r85327.
* Die outright with a pretty error message on PHP < 5.2.3 as well as PHP 4. All versions of PHP below that throw parse errors of various sorts.
* Reimplement wfDie() to provide an entry-point-dependent die-with-readable-error-message function (for instance, we want a pretty human-readable page in index.php, something wrapped in CSS/JS /*...*/ comment block in load.php, etc).
* Standardise the appearance of the catastrophic errors thrown at the top of the stack with the ones lower down (exception-within-exception, etc). There isn't really a way to do this without duplication, AFAICT.
Wikis which set $wgServer in their LocalSettings or are in a virtual
host would never be vulnerable.
For sites which show the wiki in the default host, it will depend on how
forgiving is their webserver and php stack for that garbled input, although
some kind of foolable proxy —moreover wrongly caching errors (or the default
output buffering is disabled and something incorrectly sent a previous text)—
would also need to be present in order to make that useful for a
potential attacker.
* 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.
* Made the upgrader work with SQLite
* Implemented missing schema info functionality in DatabaseSqlite
* Merged the SQLite and MySQL schemas into the one file with the help of some replaceVars() hacks.
* Moved all primary key definitions to the field definition, moved all indexes to CREATE INDEX statements, for best SQLite compatibility.
* Made all autoincrement fields primary keys, as required by SQLite.
* Removed meaningless buzzword from the category table comment
* tables.sql: s/'0'/0/
* In SQLite the index names have DB scope. Renamed archive.usertext_timestamp, user_newtalk.user_id, user_newtalk.user_ip
* SQLite does not support UPDATE with LIMIT by default. Removed all instances I could find.
* Made query errors work in the installer.
* Fixed DatabaseSqlite::lastErrno(), made SQLITE_SCHEMA errors automatically reissue the query as suggested on sqlite-users. Otherwise upgrade breaks.
* Removed miscellaneous status information from getServerVersion(), that's not the place to put it
* 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.
* Use an associative array to initialise LoadBalancer objects
* By default, use Preprocessor_DOM if available, otherwise use Preprocessor_Hash. Preprocessor_Hash has worse performance.
* Fix parserTests.php for replicated databases. Use CREATE TABLE instead of CREATE TEMPORARY TABLE if there is more than one server configured.
* Log exceptions even in command-line mode.
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.
scripts, making for cleaner reporting during batch jobs. PHP errors will also
be redirected in most cases on PHP 5.2.4 and later, switching 'display_errors'
to 'stderr' at runtime.
* Add @addtogroup tags to various classes, to try and group conceptually-related classes together.
* Add brief descriptions to various Special pages, thanks to Phil Boswell.
* Moving some docs to be right above the classes they represent, so that they are picked up.
