1eae9941d9 Fix bug in BacklinkCache: the lack of an ORDER BY clause in getLinks(), combined with the lack of sensible indexes on the categorylinks table, was causing partition() to return starts and ends scaterred randomly across the result set. For large jobs, many partitions end up being large, causing HTMLCacheUpdate::doPartialUpdate() to repartition, thus requeueing jobs in an infinite recursive loop. 
The BacklinkCache bug was there since r47317, but was relatively harmless until r54841 introduced the infinite loop issue.

4f3efbf406 Don't do any backlink batches if there are no backlinks. 2009-02-19 02:10:55 +00:00

4b66381cbf * Mostly reverted r41081 and related. Although the motivation (to save a query) is noble, it's a complex special case relying on subtle inter-module effects, making the code quite unclear and the performance advantage hard to reproduce in new code. 
* 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
