FLUSH TABLES WITH READ LOCK fails to properly detect write locked tables when running under low priority updates. The problem is that when trying to aspire a global read lock, the reload_acl_and_cache() function fails to properly check if the thread has a low priority write lock, which later my cause a server crash or deadlock. The solution is to simple check if the thread has any type of the possible exclusive write locks. mysql-test/r/flush.result: Add test case result for Bug#32528 mysql-test/t/flush.test: Add test case for Bug#32528 sql/sql_parse.cc: Although it should not matter under LOCK TABLES, use TL_WRITE_ALLOW_WRITE to emphasize that it should fail in case of any write lock. |
