2019-10-04Return EIO from p9 if flipcall.Endpoint.Connect() fails.Jamie Liu
Also ensure that all flipcall transport errors not returned by p9 (converted to EIO by the client, or dropped on the floor by channel server goroutines) are logged. PiperOrigin-RevId: 272963663

2019-06-21Remove O(n) lookup on unlink/renameMichael Pratt
Currently, the path tracking in the gofer involves an O(n) lookup of child fidRefs. This causes a significant overhead on unlinks in directories with lots of child fidRefs (<4k). In this transition, pathNode moves from sync.Map to normal synchronized maps. There is a small chance of contention in walk, but the lock is held for a very short time (and sync.Map also had a chance of requiring locking). OTOH, sync.Map makes it very difficult to add a fidRef reverse map. PiperOrigin-RevId: 254489952
2019-06-21Update pathNode documentation to reflect realityMichael Pratt
Neither fidRefs or children are (directly) synchronized by mu. Remove the preconditions that say so. That said, the surrounding does enforce some synchronization guarantees (e.g., fidRef.renameChildTo does not atomically replace the child in the maps). I've tried to note the need for callers to do this synchronization. I've also renamed the maps to what are (IMO) clearer names. As is, it is not obvious that pathNode.fidRefs is a map of *child* fidRefs rather than self fidRefs. PiperOrigin-RevId: 254446965

Otherwise future renames may miss Renamed calls. PiperOrigin-RevId: 254060946

This change also adds extensive testing to the p9 package via mocks. The sanity checks and type checks are moved from the gofer into the core package, where they can be more easily validated. PiperOrigin-RevId: 218296768 Change-Id: I4fc3c326e7bf1e0e140a454cbacbcc6fd617ab55
