attempt to create spatial index on char > 31 bytes". Attempt to create spatial index on char field with length greater than 31 byte led to assertion failure on server compiled with safemutex support. The problem occurred in mi_create() function which was called to create a new version of table being altered. This function failed since it detected an attempt to create a spatial key on non-binary column and tried to return an error. On its error path it tried to unlock THR_LOCK_myisam mutex which has not been not locked at this point. Indeed such an incorrect behavior was caught by safemutex wrapper and caused assertion failure. This patch fixes the problem by ensuring that mi_create() doesn't releases THR_LOCK_myisam mutex on error path if it was not acquired. |
