When RESTBase is turned off, Parsoid runs will no longer be triggered on template changes. This creates a new mechanism to do that, based on the RevisionDataUpdates hook called by DerivedPageDataUpdater. The new behavior is controlled by a feature flag, LinterParseOnDerivedDataUpdate, which is enabled per default. In WMF production, this should be turned off as long as we are still triggering Parsoid parses through the pregeneration mechanism in RESTBase. Note that this will not write ParserOutput to the ParserCache. On edits, pages will get parsed with Parsoid twice, once to trigger the lint data update, and once by ParsoidCachePrewarmJob to populate the ParserCache. Both parses will trigger the ParserLogLinterData hook, the lint data from the second parse is redundant. However, while ParsoidCachePrewarmJob and RevisionDataUpdates get triggered together on edits, they also get triggered separately: ParsoidCachePrewarmJob by page views with parser cache misses; and RevisionDataUpdates when pages get invalidated due to template changes. Because ParsoidCachePrewarmJob and RevisionDataUpdates generally get triggered in different situations, it seems cleaner to keep the two mechanisms independent of each other, and live with the duplicate parse on edit.
