* 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
This is a global search and replace of NS_IMAGE and NS_IMAGE_TALK with NS_FILE and NS_FILE_TALK respectively in all core files, excluding those already updated in step 1 (r44004).
* Adds Category and CategoryList classes to represent categories themselves.
* Adds a category table, giving each category a name, ID, and counts of all members, subcats only, and files.
* Adds a maintenance script to populate the category table efficiently. This script is careful to wait for slaves and should be safe to run on a live database. The maintenance script's includes file is called by update.php.
* Until the category table is populated, the patch handles weird category table rows gracefully. It detects whether they're obviously impossible, and if so, it outputs appropriate messages.
* Added page_props backend, generic parser-driven page properties which, when changed, invalidate the cache of backlinked pages on any links table. Could be used to add overlays to images depending on their deletion status, or to add icons to articles based on category membership.
* Refactored double-underscore handling in the parser.
* Moved CoreParserFunctions registration to CoreParserFunctions.
* 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
pick up the appropriate tags, and documentation blobs for classes. This is
the same as per r20769, but with the grouping changes (e.g. removing "@{{") omitted.
Please be advised that more related documentation tweaks may follow later - e.g.
Doxygen generates a log file of warnings that is 574 Kb in size, when run over
the just the trunk/phase3 code ... eek! Thankfully, much of that is just
whining about functions without documentation ;-)
Minor doc tweaks to prevent some PHPDocumentor warnings or errors when run on the includes/ directory. PHPDocumentor uses a syntax very similar to javadoc - mostly we already use this, but there were a few scattered places that were adjusted to make them consistent with the rest of the code. In practical terms, these changes were made:
* @url becomes @link
* @fixme becomes @todo
* HTML tags in descriptions must be closed / balanced.
* @bug was removed (where the bug was long fixed), or changed into a @todo (in the few situations where the bug was still pending)
* @obsolete becomes @deprecated
* Things like "/**@{{" and "/**@}}*/" which cause "unknown tag" warnings were removed
* @access must be a valid access level.
* @desc tag not needed, removed.
* Doesn't seem to like @licence, will accept @license however.
* Use full comment block notation in a few places (i.e. open block with "/**", start each line with " *", and end block with " */")
Then additional to this, to get some class docs associated with their respective classes:
* Moved some docs to right above those classes (deleting blank lines, or moving descriptions from the file headers)
* Marked some classes without docs as "@todo document"
* (done up to "class MIMEsearchPage" on the "classtrees_MediaWiki.html" page for the includes/ directory)
* Convert "$dbw =& wfGetDB( DB_MASTER );" --> "$dbw = wfGetDB( DB_MASTER );"
* convert "$skin =& $wgUser->getSkin();" --> "$skin = $wgUser->getSkin();"
For the time being have not changed the function definitions of wfGetDB() or User::getSkin() [i.e. they are still both return-by-ref], so as to ensure the interface does not change for extensions [some of which may still be trying to run on PHP4 environments]. However presumably at some point this can be changed too.
Also includes tiny tweak to newlines in parserTests - will show 1 rather than 2 newlines between the "Reading tests from" strings when in quiet mode.
* remove require_once() throughout whole code, yet left in few places
* move global functions in HttpUtils, ProxyTools, Credits to class methods
* php5 only: __autoload() now used, combined with class->file map and require()
* move initialization of $wgValidSkinNames to Skin::getSkinNames()
* few more changes that will surely break stuff.
