I am writing a custom Locker which does a check if Lock() is being called more than once and throws a panic if it does. I tested it to see if I can use it with sync.Cond, and for the most part, it was running as intended, except once in a while the panic check triggered.
Here's the dumbed down version of what I am trying to do: https://play.golang.org/p/2tWqY221RM I cannot get it to reproduce on the Go Playground, but copy paste it to your local computer and see if you get it to panic. Here's what I got: panic: Cannot lock twice goroutine 5 [running]: main.(*CustomLocker).Lock(0xc42000e2e0) /.../go/src/github.com/test/custom_locker.go:18 +0xc9 main.main.func1(0xc4200142c0, 0xc42000e2f0, 0xc42000e2d0) /.../go/src/github.com/test/custom_locker.go:42 +0x37 created by main.main /.../go/src/github.com/test/custom_locker.go:50 +0x159 exit status 2 I thought sync.Cond.Wait() should Unlock(), sleeps itself, then when awaken by Broadcast() try to Lock() again? -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
