The IAM server's KeepConnectedToMaster goroutine used context.Background(),
which is non-cancellable, causing the goroutine and its gRPC connections
to leak on server shutdown.
Problem:
go masterClient.KeepConnectedToMaster(context.Background())
- context.Background() never cancels
- KeepConnectedToMaster goroutine runs forever
- gRPC connection to master stays open
- No way to stop cleanly on server shutdown
Result: Resource leaks when IAM server is stopped
Fix:
1. Added shutdownContext and shutdownCancel to IamApiServer struct
2. Created cancellable context in NewIamApiServerWithStore:
shutdownCtx, shutdownCancel := context.WithCancel(context.Background())
3. Pass shutdownCtx to KeepConnectedToMaster:
go masterClient.KeepConnectedToMaster(shutdownCtx)
4. Added Shutdown() method to invoke cancel:
func (iama *IamApiServer) Shutdown() {
if iama.shutdownCancel != nil {
iama.shutdownCancel()
}
}
5. Stored masterClient reference on IamApiServer for future use
Benefits:
- Goroutine stops cleanly when Shutdown() is called
- gRPC connections are closed properly
- No resource leaks on server restart/stop
- Shutdown() is idempotent (safe to call multiple times)
Usage (for future graceful shutdown):
iamServer, _ := iamapi.NewIamApiServer(...)
defer iamServer.Shutdown()
// or in signal handler:
sigChan := make(chan os.Signal, 1)
signal.Notify(sigChan, syscall.SIGTERM, syscall.SIGINT)
go func() {
<-sigChan
iamServer.Shutdown()
os.Exit(0)
}()
Note: Current command implementations (weed/command/iam.go) don't have
shutdown paths yet, but this makes IAM server ready for proper lifecycle
management when that infrastructure is added.
