After a locking error the open table(s) were not fully cleaned up for reuse. But they were put into the open table cache even before the lock was tried. The next statement reused the table(s) with a wrong lock type set up. This tricked MyISAM into believing that it don't need to update the table statistics. Hence CHECK TABLE reported a mismatch of record count and table size. Fortunately nothing worse has been detected yet. The effect of the test case was that the insert worked on a read locked table. (!) I added a new function that clears the lock type from all tables that were prepared for a lock. I call this function when a lock failes. No test case. One test would add 50 seconds to the test suite. Another test requires file mode modifications. I added a test script to the bug report. It contains three cases for failing locks. All could reproduce a table corruption. All are fixed by this patch. This bug was not lock timeout specific. sql/lock.cc: Bug#18544 - LOCK TABLES timeout causes MyISAM table corruption Resetting the lock type in the open table(s) lock data after a locking error. |
