Changes in MySQL 5.1.70 (2013-06-03)

   Bugs Fixed

     * Important Change; Replication: When the server was running
       with --binlog-ignore-db and SELECT DATABASE() returned NULL
       (that is, there was no currently selected database),
       statements using fully qualified table names in dbname.tblname
       format were not written to the binary log. This was because
       the lack of a currently selected database in such cases was
       treated as a match for any possible ignore option rather than
       for no such option; this meant that these statements were
       always ignored.
       Now, if there is no current database, a statement using fully
       qualified table names is always written to the binary log.
       (Bug #11829838, Bug #60188)

     * InnoDB: Valgrind testing returned memory leak errors which
       resulted from a regression introduced by the fix for Bug
       #11753153. The dict_create_add_foreign_to_dictionary function
       would call pars_info_create but failed to call pars_info_free.
       (Bug #16754901)

     * InnoDB: The fix for Bug #16722314 resulted in a linker error.
       (Bug #16798595)

     * InnoDB: Crash recovery would fail with a !recv_no_log_write
       assertion when reading a page. (Bug #16405422)

     * Replication: Using the --replicate-* options (see Replication
       Slave Options and Variables
(http://dev.mysql.com/doc/refman/5.1/en/replication-options-sl
       ave.html)) could in some cases lead to a memory leak on the
       slave. (Bug #16056813, Bug #67983)

     * The WKB reader for spatial operations could fail and cause a
       server exit. (Bug #16451878)

     * A GROUP_CONCAT() invocation containing subquery having an
       outer reference caused the server to exit. (Bug #16347343)

     * For debug builds, GROUP_CONCAT(... ORDER BY) within an ORDER
       BY clause could cause a server exit. (Bug #16347426)

     * A prepared statement that used GROUP_CONCAT() and an ORDER BY
       clause that named multiple columns could cause the server to
       exit. (Bug #16075310)

     * ORDER BY MATCH ... AGAINST could cause a server exit. (Bug
       #16073689)

     * When a partition is missing, code in ha_innodb.cc would retry
       10 times and sleep for a microsecond each time while holding
       LOCK_open. The retry logic for partitioned tables was
       introduced as a fix for Bug#33349 but did not include a test
       case to validate it. This fix removes the retry logic for
       partitioned tables. If the problem reported in Bug#33349
       reappears, a different solution will be explored. (Bug
       #15973904)

     * The mysql.server script exited with an error if the status
       command was executed with multiple servers running. (Bug
       #15852074)

     * When processing row-based-replication events in the old binary
       log format from prior to MySQL 5.1 GA builds, mysqlbinlog
       could result in out-of-bounds heap buffer reads and undefined
       behaviour. (Bug #14771299)

     * The mysql client allocated but did not free a string after
       reading each line in interactive mode, resulting in a memory
       leak. (Bug #14685362)

     * Grouping by an outer BLOB column in a subquery caused a server
       exit. (Bug #13966809, Bug #14700180)

     * The url columns in the mysql datatbase help tables were too
       short to hold some of the URLs in the help content. For new
       installations, these columns are now created as type TEXT to
       accommodate longer URLs.
       For upgrades, mysql_upgrade does not update the columns.
       Modify them manually using these statements:
ALTER TABLE mysql.help_category MODIFY url TEXT NOT NULL;
ALTER TABLE mysql.help_topic MODIFY url TEXT NOT NULL;
       (Bug #61520, Bug #12671635)

     * The test for stack overrun did not work for recent gcc
       versions and could lead to server exit. (Bug #62856, Bug
       #13243248)
       References: See also Bug #42213.

     * IF() function evaluations could produce different results when
       executed in a prepared versus nonprepared statement. (Bug
       #45370, Bug #11753852)
