changeset 18309:cfeab932cff7

localrepo: don't refresh filecache entries that aren't in __dict__ We call invalidate to remove properties from __dict__ because they're possibly outdated and we'd like to check for a new version. Next time the property is accessed the filecache mechanism checks the current stat info with the one recorded at the last time the property was read, if they're different it recreates the property. Previously we refreshed the stat info on all properties in the filecache when the lock is released, including properties that are missing from __dict__. This is a problem because: l = repo.lock() repo.P # stat info S for P is recorded in _filecache <changes are made to repo.P indirectly, e.g. underlying file is replaced> # P's new stat info = S' l.release() # filecache refreshes, records S' as P's stat info At this point our filecache contains P with stat info S', but P's version is from S, which is outdated. The above happens during _rollback and strip. Currently we're wiping the filecache and forcing everything to reload from scratch which works but isn't the right solution.
