YaacovHazan ff27217639 stabilize tests that involved with load handlers (#8967) ... When test stop 'load handler' by killing the process that generating the load, some commands that already in the input buffer, still might be processed by the server. This may cause some instability in tests, that count on that no more commands processed after we stop the `load handler' In this commit, new proc 'wait_load_handlers_disconnected' added, to verify that no more cammands from any 'load handler' prossesed, by checking that the clients who genreate the load is disconnceted. Also, replacing check of dbsize with wait_for_ofs_sync before comparing debug digest, as it would fail in case the last key the workload wrote was an overridden key (not a new one). Affected tests Race fix: - failover command to specific replica works - Connect multiple replicas at the same time (issue #141), master diskless=$mdl, replica diskless=$sdl - AOF rewrite during write load: RDB preamble=$rdbpre Cleanup and speedup: - Test replication with blocking lists and sorted sets operations - Test replication with parallel clients writing in different DBs - Test replication partial resync: $descr (diskless: $mdl, $sdl, reconnect: $reconnect (cherry picked from commit 32a2584e07)		2021-07-21 21:06:49 +03:00
