2021-01-26Implement error on pointersTamir Duberstein
This improves type-assertion safety. PiperOrigin-RevId: 353931228
2020-12-04Require sync.RWMutex to lock and unlock from the same goroutineMichael Pratt
This is the RWMutex equivalent to the preceding sync.Mutex CL. Updates #4804 PiperOrigin-RevId: 345681051
2020-06-03Fix data race on f.offset.Nicolas Lacasse
We must hold f.mu to write f.offset. PiperOrigin-RevId: 314582968
2020-01-27Update package locations.Adin Scannell
Because the abi will depend on the core types for marshalling (usermem, context, safemem, safecopy), these need to be flattened from the sentry directory. These packages contain no sentry-specific details. PiperOrigin-RevId: 291811289
2020-01-09New sync package.Ian Gudger
* Rename syncutil to sync. * Add aliases to sync types. * Replace existing usage of standard library sync package. This will make it easier to swap out synchronization primitives. For example, this will allow us to use primitives from github.com/sasha-s/go-deadlock to check for lock ordering violations. Updates #1472 PiperOrigin-RevId: 289033387

2019-02-08Add fs.AsyncWithContext and call it in fs/gofer/inodeOperations.Release.Nicolas Lacasse
fs/gofer/inodeOperations.Release does some asynchronous work. Previously it was calling fs.Async with an anonymous function, which caused the function to be allocated on the heap. Because Release is relatively hot, this results in a lot of small allocations and increased GC pressure, noticeable in perf profiles. This CL adds a new function, AsyncWithContext, which is just like Async, but passes a context to the async function. It avoids the need for an extra anonymous function in fs/gofer/inodeOperations.Release. The Async function itself still requires a single anonymous function.

2018-11-27Fix data race in fs.Async.Nicolas Lacasse
Replaces the WaitGroup with a RWMutex. Calls to Async hold the mutex for reading, while AsyncBarrier takes the lock for writing. This ensures that all executing Async work finishes before AsyncBarrier returns. Also pushes the Async() call from Inode.Release into gofer/InodeOperations.Release(). This removes a recursive Async call which should not have been allowed in the first place. The gofer Release call is the slow one (since it may make RPCs to the gofer), so putting the Async call there makes sense.
