This section documents all changes and bug fixes applied since the release of 1.2.3.
The required Python version changed from 2.7 to 2.6, to better accommodate a wider range of operating systems. (Bug #16953933)
START SLAVE statement failed when a MySQL
server was started with the
and with autocommit mode disabled. This fix provides a
workaround by enabling autocommit ("SET autocommit=1") before
START SLAVE statement. This
allows the utility to function with past and future versions of
(Bug #17029968, Bug #16745357, Bug #68657)
The MUT test suite failed or run slowly on systems with a low amount of memory. This was improved by now killing MySQL instances that are no longer required to execute other tests. (Bug #16991428)
The mysqldiskusage utility crashed when used on servers with strangely named databases, such as "foo`bar". The encoding was updated so the proper database directory is now referenced. (Bug #16920452)
When executing mysqldbcompare with
--difftype=sql on a table without a primary
key, the uncommented text "No primary key found." was added to
the generated SQL. This text is now commented.
(Bug #16920156, Bug #69227)
The help text for the mysqluc utility contained outdated copyright information. (Bug #16860031, Bug #16832071, Bug #69281)
Using long variables names in mysqluc would
throw an unhandled exception when executing
variables. The variable names are now truncated if
their width exceeds the maximum allowable width.
Support for passing in multiple variables to the mysqluc utility was also fixed. (Bug #16832161, Bug #69284)
The mysqlindexcheck utility was not quoting objects identifiers with backticks in the generated SQL. (Bug #16832125, Bug #69283)
The mysqldiskusage utility's
innodb_file listing did not use the system's
localization for displaying digits.
(Bug #16832089, Bug #69282)
The mysqlfailover utility was incorrectly
GRANT OPTION privilege. It
now checks if slaves have
RELOAD privileges, which are now required to
successfully execute failover due to recent improvements.
Termination of the master connection for the mysqlfailover utility caused an ungraceful failure. (Bug #16805721, Bug #69210)
While performing a switchover, some errors were printed but not saved to the log file. (Bug #16800645, Bug #69195)
The mysqlserverinfo utility displayed misleading error information when accessing a remote MySQL server. The utility would attempt to retrieve the configuration defaults of the specified remote MySQL server, but they can only be retrieved locally. A proper warning is now emitted. (Bug #16799550, Bug #69197)
--start-timeout option was added to the
mysqlserverinfo utility. It determines the
number of seconds to wait for the server to be online when
started in read-only mode using the
option. The default value is 10 seconds.
(Bug #16799550, Bug #69197)
The mysqldiskusage utility did not display
the binary log usage data when used from a remote host. It is
now displayed using
SHOW BINARY LOGS when the
utility is executed from a remote host. Now, the required
privileges (to execute required queries) are also checked before
retrieving the logs usage, and an appropriate error is issued
The list of relay log files was not displayed properly if
relay_log_basename was empty. The default
prefix is now used in this case.
(Bug #16799466, Bug #69198)
--status=STATUS option was added to the
mysqlauditgrep utility. It accepts a
comma-separated list of MySQL error codes (integers).
(Bug #16703480, Bug #69034)
The mysqlauditgrep utility option
--query-type was improved to avoid false
(Bug #16617624, Bug #68891)
The utilities console (mysqluc) now reads the help and options information from other utilities on-demand, rather than at startup. (Bug #16344168)
The replication utilities would halt operations with a "Not
enough permissions" error even with
--skip-grant-tables enabled. The user
privileges check is now disabled if the MySQL server has grants
The mysqldbcopy utility did not copy the default charset from the original database. mysqldbcopy will now query the default charset and collation from the original database and set these values (if they exist) on the destination database. (Bug #13893128)
The mysqldbcopy utility failed to copy
foreign key constraints while it cloned databases, and the
--default-storage-engine options did not
function correctly while cloning databases.
(Bug #13519748, Bug #63783)
The default charset for MySQL connections is now set to "utf8" instead of latin1, in order to support non-latin data. (Bug #13417229, Bug #14383887, Bug #65273)
