* r41081 was causing the job queue to be flooded with tiny htmlCacheUpdate jobs which were less than the batch size and so, according to the original logic, should have been done immediately. This was causing template updates to be delayed even when the template has few backlinks. This is fixed.
* Introduced a shared cache called BacklinkCache with the main purpose of sharing data from these backlink queries, thus recovering the performance of r41081.
* Refactored backlink partitioning code, which in r40741 was copied from HTMLCacheUpdate to LinksUpdate with a bug intact. The bug caused every htmlCacheUpdate or refreshLinks2 job to be split into at least two pieces even when number of rows is less than the batch size.
* Fixed a bug from r40741 causing refreshLinks2 jobs with end=false to be ignored.
* Made SquidUpdate::newFromTitles() accept a TitleArray
Regressions caused by this:
"Use an anonymous user to get the parser options and the parser cache key, thus wikitext rendering is not depending of some sepcific user options such as lang, ..."
User-specific options such as stub threshold were still applying in the parser, but not taken into account in the parser hash key. As a result, the caches were corrupt, saving different options into the anonymous-default options cache.
* Respect the language given with parser options
* Replace parameters before expanding its own templates/functions, like $wgOut->addWikiMsg() does
* (bug 14404) Force content language when parsing the text to pass to LinksUpdate
And some tweaks at save time:
* Use an anonymous user to get the parser options and the parser cache key, thus wikitext rendering is not depending of some sepcific user options such as lang, ...
* Same for the refresh link job
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.
This is an old PHP 4-ism; only needed today if you want to be able to replace the singleton with another object by using the reference as an lval. :)
Killing them because they annoy me.
* Move Jobs left in JobQueue.php to their own file
* Ditch $wgCustomJobs in favour of $wgJobClasses, which acts as a dictionary and allows extensions to add custom jobs
* Standardise Job derivative constructors and update everywhere
* Make sure all overriding implementations of Job::run() return true to avoid bogus "Error" report in runJobs.php
