Changes in MySQL 5.1.70 (Not yet released)

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)
