This commit enables tracking time of the background tasks and on replies, opening the door for properly tracking commands that rely on blocking / background work via the slowlog, latency history, and commandstats. Some notes: - The time spent blocked waiting for key changes, or blocked on synchronous replication is not accounted for. - **This commit does not affect latency tracking of commands that are non-blocking or do not have background work.** ( meaning that it all stays the same with exception to `BZPOPMIN`,`BZPOPMAX`,`BRPOP`,`BLPOP`, etc... and module's commands that rely on background threads ). - Specifically for latency history command we've added a new event class named `command-unblocking` that will enable latency monitoring on commands that spawn background threads to do the work. - For blocking commands we're now considering the total time of a command as the time spent on call() + the time spent on replying when unblocked. - For Modules commands that rely on background threads we're now considering the total time of a command as the time spent on call (main thread) + the time spent on the background thread ( if marked within `RedisModule_MeasureTimeStart()` and `RedisModule_MeasureTimeEnd()` ) + the time spent on replying (main thread) To test for this feature we've added a `unit/moduleapi/blockonbackground` test that relies on a module that blocks the client and sleeps on the background for a given time. - check blocked command that uses RedisModule_MeasureTimeStart() is tracking background time - check blocked command that uses RedisModule_MeasureTimeStart() is tracking background time even in timeout - check blocked command with multiple calls RedisModule_MeasureTimeStart() is tracking the total background time - check blocked command without calling RedisModule_MeasureTimeStart() is not reporting background time
