This supercedes I6d03bf2a, using better names for the new classes and
incorporating the changes requested by Aaron.
This change introduces the base class SecondaryDataUpdate to be used for any
updates that need to be applied when a page is changed or deleted. Until now,
this was done by the LinksUpdate class for updates and WikiPage::doDeletionUpdates
upon deletion. This patch uses a list of SecondaryDataUpdates in both cases.
This allows extensions (e.g. via the ContentHandler facility, once that is in) to
easily specify what needs to be done when a page is updated or deleted in order to
keep any secondary data stores (such as link tables) in sync.
Note that limited transactional logic is also introduced, so SecondaryDataUpdate
can be implemented to only commit their changes if all updates were performed
sucessfully.
Patch Set 2: fixing some coding style issues mentioned by Nikerabbit.
Patch Set 4: some stuff I kept from the old LinksUpdate class needs cleanup,
but might break extensions when changed. Marking as todo for now.
Patch Set 5: fixed misnamed member in LinksDeletionUpdate (thanks Aaron).
Change-Id: Ibe3e88fadd8c1d4063cf13bb6972f2a23569a73f
* Changed SpecialPageFactory::capturePath() to take the same parameters as SpecialPageFactory::executePath() (except the last one) and made it always return a bool instead of bool-or-string. The result HTML can be fetched from the OutputPage object of the context.
* Added module styles, scritps and messages members to ParserOutput in addition to modules. The first one is needed to display Special:RecentChanges correctly when transcluded since EnhancedChangesList::beginRecentChangesList() calls addModuleStyles( 'mediawiki.special.changeslist' )
Yes, this means that you can use {{Special:Recentchanges|enhanced=0}} to use the old changes list. For the ones that wonder, {{Special:Recentchanges|uselang=something}} will not work since the Language object is forced to the one used by the parser.
AFAICT, result of ParserOutput::getUsedOptions() is only used by ParserOptions::optionsHash() but that method doesn't account for a non-array value.
Patch supplied on bug.
Breaks unit tests as below, not going to be able to fix them before I disappear for the evening, so might aswell leave trunk clean

Also fixed a bug in ParserOutput when no option is used; otherwise getUsedOptions() will return false and throw warnings in ParserOptions::optionsHash().
Doing this allows skins to override doEditSectionLinks without poluting the parser cache or fragmenting the parser cache more.
As a side effect it eliminates the primary cause of user language based parser cache fragmentation.
Because this makes most old parser cache entries invalid $wgUseEditSectionTokens is provided so that large installations like Wikipedia can keep their old parser cache entries.
Like langlinks, this stores the interwiki prefix (as iwl_prefix) and full page title (as iwl_title), attached to the page doing the liking (as iwl_from -> page_id).
Unlike langlinks, there can be multiple entries stored per interwiki prefix.
Updater to add the table confirmed on MySQL, untested on SQLite but should work.
Someone may still need to add and test a PostgreSQL updater.
Refactored makeWhereFrom2d() out of LinkBatch to Database so it could be re-used for the similar mapping for the interwiki links, which need a string prefix rather than an int namespace key.
Also cleaned it up internally to reuse existing code for building where clauses from arrays. (Tim & Domas -- if the previous more verbose code was there to reduce function call and array processing overhead on very large link lists, feel free to unroll it again if the difference is measurable. Just swap the var names around from the old LinkBatch code and escape the base key value if it's not an integer, it'll be functionally equivalent.)
