Aude has uploaded a new change for review.
https://gerrit.wikimedia.org/r/188965
Change subject: Split SiteLookup interface from SiteStore
......................................................................
Split SiteLookup interface from SiteStore
* SiteLookup interface is added, and SiteStore extends
it. (any SiteStore type hints can be changed to use
SiteLookup if all they need is lookup functionality)
* Memcached based SiteStore code is split from the
database SiteStore, and SiteSQLStore is deprecated.
If no caching is desired when using a SiteStore, then
use a SiteDBStore instance, instead of passing $source
parameter in SiteStore::getSite and SiteStore::getSites.
* SiteListFileCache renamed to FileBasedSiteLookup and
implements SiteLookup, and SitesListFileCacheBuilder
to SitesFileCacheBuilder.
* Renamed config sites cache setting, from wgSitesCacheFile
to wgSitesFileCache, for more naming consistency.
Bug: T77990
