* We used to have parameters to ignore errors, but they're obsolete now that we have exceptions. Implemented ES master failover using exceptions instead.
* Changing the number of DB connection attempts from 3 to 2 for some random getConnection() calls is almost pointless, adds lots of ugly formal parameters all of the place, and misses the big picture. It should be 2 by default, based on the original rationale. Any reasonable implementation of failover should have zero timeouts per request, by storing state. Changed the default to 2, or 1 if a long timeout is set.
* On read, spend less time checking on dead slaves
* Add randomInsert() to ES. This does the cluster picking for us
* Make revision text use randomInsert(). On write, fails-over to other clusters as needed instead of throwing db errors
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!
