* Moved the global functions to GlobalFunctions.php, where they are now just convenience wrappers. Made them return non-references. Updated callers (none found in extensions).
* Added an advanced configuration method, $wgObjectCaches, which allows a lot more detail in the object cache configuration than $wgMainCacheType.
* Made all object cache classes derive from BagOStuff.
* Split the MWMemcached class into a generic client class and a MediaWiki-specific wrapper class. The wrapper class presents a simple BagOStuff interface to calling code, hiding memcached client internals, and will simplify the task of supporting the PECL extension.
* Added some extra constructor parameters to MWMemcached, configurable via $wgObjectCaches.
* Removed the *_multi() methods from BagOStuff, my grepping indicates that they are not used.
* Rewrote FakeMemCachedClient as a BagOStuff subclass, called EmptyBagOStuff.
* Added an optional "server" parameter to SQLBagOStuff. This allows the server holding the objectcache table to be different from the server holding the core DB.
* Added MultiWriteBagOStuff: a cache class which writes to multiple locations, and reads from them in a defined fallback sequence. This can be used to extend the cache space by adding disk-backed storage to existing in-memory caches.
* Made MWMemcached::get() return false on failure instead of null, to match the BagOStuff documentation and the other BagOStuff subclasses. Anything that was relying on it returning null would have already been broken with SqlBagOStuff.
* Fixed a bug in the memcached client causing keys with spaces or line breaks in them to break the memcached protocol, injecting arbitrary commands or parameters. Since the PECL client apparently also has this flaw, I implemented the fix in the wrapper class.
* Renamed BagOStuff::set_debug() to setDebug(), since we aren't emulating the memcached client anymore
* Fixed spelling error in MWMemcached: persistant -> persistent
* Cripple the old installer (entry point is gone, supporting code immediately exits). Keeping the latter for reference still :)
* Move posix_isatty() wrapper to Maintenance.php, all CLI scripts include this
* Clarify docs on archive() deprecation and removal - hasn't been used going back thru 1.15
* Clarify docs on dbsource() deprecation and removal - was in wide use thru 1.15. 1.16 removed all extension usages
* Move the two PHP bug tests to a file with the other installer files, moved them to more logical places in new install/update sequence
* Remove mw_have_dl/mw_get_session_save_path, zero callers
* Move readconsole() and helpers to be a static method on Maintenance, no extensions have used it since 1.15 either
* Put MemCachedClientforWiki in memcached-client.php so that maintenance/mctest.php doesn't crash when $wgMainCacheType is not CACHE_MEMCACHED
Based on a patch by Kim Hyun-Joon
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.
* Fix some scripts that assumed include_path was set with various additional directories
Stuff now seems to mostly work when not overriding include_path.
Taking that out of LocalSettings is the next step... whee!
* use configured cache servers for mctest.php
* bucket details in mcc.php
* fix input validation and remove debugging code in compressOld
* full ID range for moveToExternal
* fix resolveStubs.php for compatibility with older serialized data
* maximum line length for bar graphs in getLagTimes.php
* recognize specieswiki in rebuildInterwiki.inc
* --purge option to do additional parser-cache purging for purgeList.php
* default changed in MiniDonation extension
* profile unicode cleanup in Xml
* log slow parses in Article.php
* profile wfMsgReal
* log mkdir failures
* profile AutoLoader
* rebuild empty DjVu metadata containing ''
* security fix for DjVu metadata retrieval
