execution_queue_join安全吗? #2775

Closed zergvszerg closed 1 month ago

zergvszerg commented 1 month ago

使用场景是先execution_queue_stop再间隔不定时间execution_queue_join, 但考虑到resource pool会归还使用完的资源, ExecutionQueueId可能会被复用, 那么execution_queue_join就可能等待在一个还没有execution_queue_stop的execution queue上, 从而不安全, 请问有什么好的解决方法?

ExecutionQueueId是是带版本号的（类似bthread_t），归还之后的资源的版本号已经变了，所以execution_queue_join是安全的，不会等其他execution_queue。
