MySQL 5.1 Release Notes  /  Changes in MySQL 5.1.72 (2013-09-20)

Changes in MySQL 5.1.72 (2013-09-20)

Bugs Fixed

  • InnoDB: The row_sel_sec_rec_is_for_clust_rec function would incorrectly prepare to compare a NULL column prefix in a secondary index with a non-NULL column in a clustered index. (Bug #17312846)

  • InnoDB: An incorrect purge would occur when rolling back an update to a delete-marked record. (Bug #17302896)

  • InnoDB: InnoDB would rename a user-defined foreign key constraint containing the string _ibfk_ in its name, resulting in a duplicate constraint. (Bug #17076737, Bug #69693, Bug #17076718, Bug #69707)

  • InnoDB: Rolling back an INSERT after a failed BLOB write would result in an assertion failure. The assertion has been modified to allow NULL BLOB pointers if an error occurs during a BLOB write. (Bug #16971045)

  • InnoDB: The srv_master_thread background thread, which monitors server activity and performs activities such as page flushing when the server is inactive or in a shutdown state, runs on a one second delay loop. srv_master_thread failed to check if the server is in a shutdown state before sleeping. (Bug #13417564, Bug #63276)

  • InnoDB: An infinite loop could occur in buf_page_get_gen when handling compressed-only pages. (Bug #12560151, Bug #61132)

  • Within a stored program, comparison of the value of a scalar subquery with an IN clause resulted in an error for the first execution and raised an assertion for the second execution. (Bug #17029399)

  • The my_strtoll10() function could incorrectly convert some long string-format numbers to numeric values and fail to set the overflow flag. (Bug #16997513)

  • For queries that accessed an INFORMATION_SCHEMA table in a subquery, an attempt to lock a mutex that had already been locked could cause a server crash. (Bug #11765744)

  • mysqldump wrote SET statements as SET OPTION, which failed when reloaded because the deprecated OPTION keyword has been removed from SET syntax. (Bug #67507, Bug #15844882)

  • For DIV expressions, assignment of the result to multiple variables could cause a server crash. (Bug #59241, Bug #11766191)

    References: See also Bug #8457.

  • If one connection changed its default database and simultaneously another connection executed SHOW PROCESSLIST, the second connection could access invalid memory when attempting to display the first connection's default database. memory. (Bug #58198, Bug #11765252)
