* Ensure the mutex is not copied, even when the nodeServer is copied by storing a pointer to the mutex, instead of the mutex itself. * Use Mutex instead of RWMutex, as having two readers of the variable at the same time means we are going to write the state at the same time, corrupting the state file on storage. * Mutex / RWMutex are not recursive / re-entrant in Go, so in two cases we do not call `Unlock()` through `defer` as `persistState()` also takes the lock. * As a rule of thumb, Locking a Mutex should be as close as possible to the resource requiring it, to minimize the size of the critical section / the time spent holding the lock. * Remount each volume in a goroutine, with a rate limits of the number of active routine to prevent contention, and keep under control startup times.
* Refactor & cleanups (#78) * Propagate context more thoroughly (#79) * Tests after introduction of DriverConfig (#80) * The error handling was creating issues ignored previously (#81) * Use node tmp folder for the mounts recovery state (#82) * Wait for the deamon to be ready (#83) * Fix empty json body & memory units in yaml (#85) --------- Co-authored-by: Tasko Olevski <[email protected]>
