ParserCache is already a singleton, making it a good candidate for a service. $parserMemc is an odd global (it lacks the "wg" prefix) and is ripe for deprecation. The following are now deprecated: * $parserMemc global * ParserCache::singleton() * wfGetParserCacheStorage() A ParserCache::getCacheStorage() method was added for cases where direct access to the underlying BagOStuff object is necessary. Usage of $parserMemc will emit deprecation warnings through the DeprecatedGlobal class mechanism. All usage in core was migrated. Also take this opportunity to inject the $wgCacheEpoch global value into ParserCache. This will require an update to the FlaggedRevs extension. Change-Id: I2ac7afff0d8522214329248c3d1cdccd0f72bbd4
