annotate rust/hg-core/src/dirstate_tree/status.rs @ 49547:8ee3889bab92 stable

rust-status: save new dircache even if just invalidated There was a functional race between invalidating the cache (not acted upon until the end of the status algorithm) and populating the new cache (which relies upon an up-to-date version of the cache). We simply inform the cache populating function that we've just invalidated the cache for this particular directory since the information is present in the same scope.
