There are several methods for deadlock detection. One approach is to periodically check the system's resource allocation state and look for circular wait conditions. Another method involves using wait-for graphs
Thus, for each lock initialization, this code creates a static variable (__key) and uses its address as the key identifying the type of the lock. Since any particular type of lock tends to be initialized in a single place, this trick associates the same key with every lock of the same ...

In deadlock detection, the operating system considers that a deadlock situation will occur and then it will identify it. No methods for prevention or avoidance of deadlocks are applied here. So, the OS analyses if there is a deadlock. If detected, recovery methods are applied. ...
In the meantime, a clumsy workaround is to run some big dummy insert + delete in your transaction first, and only after that proceed to do the actual work. The dummy operation will raise the priority of your transaction if a deadlock is encountered. Regards, Heikki lock0lock.c: if (ut...
Summary: We had show_query_digest that shows query digest and skips physical records in most cases for SHOW ENGINE STATUS already for sensitive productions, but it doesn't work for deadlock detection part of the output. The reason is deadlock information are collected in the background in a...
DDL and FLUSH TABLES statements affecting same set of tables was executed in heavily concurrent environment. This deadlock occurred when several connections tried to perform deadlock detection in metadata locking subsystem. The first connection started traversing wait-for graph, encountered sub-graph repr...
