> Looks like my fix also caused deadlock: > > * In the watermark evaluation loop, we always get `refreshCond.L` first and then `ss.mu`. > * However, in `PersistBundle()` (a separate Go Routine), when we need to `addPending` to aggregate kind, we first obtain `ss.mu`. Then when evaluating trigger bundle, we need to obtain `refreshCond.L` for checking processing time in the scenario of not using real-time clock. To resolve the deadlock mentioned here, we will have to make sure `refreshCond.L` is acquired before `ss.mu` whenever we need to access `em.processTimeEvents`. -- This is an automated message from the Apache Git Service.
