* 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 * CLI code * servers configurations * ControllerServer * NodeServer * Cleanup warnings in: * controllerserver.go * main.go * Use tags to specify json field names on permanent storage * Make DriverVersion a constant * Protect activeVolume while reading for the metrics * Compute len(ns.mountedVolumes) once
Adapt function prototypes
- Use a folder name on the host which contains the deployment, to prevent conflicts in case of multiple deployment on the same host. - Cleaned up a bit the templates to make it easier to compare. - Use a folder under /tmp so that state is cleaned on node reboot, but kept between pod/container restarts --------- Co-authored-by: Tasko Olevski <olevski90@gmail.com>
