sync: improve race instrumentation of WaitGroup · 0f4897ae

Dmitriy Vyukov authored Jun 10, 2013

Do not synchronize Add(1) with Wait().
Imitate read on first Add(1) and write on Wait(),
it allows to catch common misuses of WaitGroup:
- Add() called in the additional goroutine itself
- incorrect reuse of WaitGroup with multiple waiters
