Guy Benoish	193fc241ca	Fix memory corruption in moduleHandleBlockedClients ... By using a "circular BRPOPLPUSH"-like scenario it was possible the get the same client on db->blocking_keys twice (See comment in moduleTryServeClientBlockedOnKey) The fix was actually already implememnted in moduleTryServeClientBlockedOnKey but it had a bug: the funxction should return 0 or 1 (not OK or ERR) Other changes: 1. Added two commands to blockonkeys.c test module (To reproduce the case described above) 2. Simplify blockonkeys.c in order to make testing easier 3. cast raxSize() to avoid warning with format spec	2020-04-07 16:52:03 +02:00
Guy Benoish	40295fb3fe	Modules: Fix blocked-client-related memory leak ... If a blocked module client times-out (or disconnects, unblocked by CLIENT command, etc.) we need to call moduleUnblockClient in order to free memory allocated by the module sub-system and blocked-client private data Other changes: Made blockedonkeys.tcl tests a bit more aggressive in order to smoke-out potential memory leaks	2020-02-04 10:23:48 +01:00
