Title Body

The common solution to preventing deadlock in code is to make sure the sequence of locking occur in a common manner regardless of which thread is accessing the resources. For example given threads T1 and T2, where T1 accesses resource A and then B and T2 accesses resource B and then A. Locking the resources in the order they are needed causes a dead-lock. The simple solution is to lock A and then lock B, regardless of the order specific thread will use the resources. Problematic situation: Thread1 Thread2 ------- ------- Lock Resource A Lock Resource B Do Resource A thing... Do Resource B thing... Lock Resource B Lock Resource A Do Resource B thing... Do Resource A thing... Possible Solution: Thread1 Thread2 ------- ------- Lock Resource A Lock Resource A Lock Resource B Lock Resource B Do Resource A thing... Do Resource B thing... Do Resource B thing... Do Resource A thing... My question is what other techniques, patterns or common practices are used in coding to guarantee dead lock prevention?
