Changes in MySQL Utilities 1.6.4 (2016-08-05)

Functionality Added or Changed

      * Added a new --master-fail-retry option to the
        mysqlfailover utility that allows the user to specify an
        additional delay for detecting when the master has
        failed. The new option allows scenarios where the network
        may have severe latency issues, the server is busy, or
        the server is being rebooted, thereby reducing the
        possibility of false positive failover events.
        (Bug #22878052)

Bugs Fixed

      * Starting with MySQL 5.7.13, some platform distributions
        display a different version string for the command,
        "mysqld --version". For example,
        "5.7.13-0ubuntu0.16.04.2" versus "5.7.13". The utilities
        now correctly identify the version for these server
        versions, or any server with a version string containing
        more than two periods. Without this fix, some utilities
        would incorrectly identify the server version and produce
        warnings, errors, or fail. (Bug #24348569)

      * Corrects an exception thrown for hostname aliases that
        had more than (2) segments. For example, local.mydomain
        contains 2, localhost.mydomain.local contains (3), which
        would result in a catastrophic error "too many values"
        causing the utility to crash. (Bug #23300260)

      * Corrects a problem found when copying tables that
        contained NOT NULL blob fields. When blob fields are
        marked NOT NULL, the copy process would fail with an SQL
        error when inserting data into the target table.
        Copying NOT NULL blob fields is not supported. The
        utility now checks all tables in the list of databases
        for NOT NULL blob fields. If any are found, the database
        and table names are printed along with an error message.
        A workaround is to drop the NOT NULL definition on blob
        fields before the copy and add it after the copy
        completes. (Bug #23111808, Bug #78084)

      * Specifying the --testdir option resulted in unexpected
        behavior when verifying results because the path of the
        directory expected to contain the test results was not
        modified accordingly. (Bug #22934469, Bug #80754)

      * Adds the ability to specify a connection timeout value
        passed to Connector/Python (the connection to MySQL) for
        the mysqlfailover utility. More specifically, it allows a
        user to override Connector/Python's connection_timeout
        default value of 10. (Bug #22932375, Bug #80747)

      * Adds checks for the --exclude option to the
        mysqldbcompare, mysqldbcopy, and mysqldbexport utilities
        to determine if the pattern supplied has any special
        characters (such as an asterisk) which may indicate that
        the pattern could be a regex pattern. If there are
        special non-SQL LIKE pattern characters, and the user has
        not specified the --regexp option, a warning is presented
        to suggest the user may want to check the pattern using
        the --regexp option. (Bug #22905132)

      * Corrects an issue with the --rpl-user and
        --discover-slaves-login options where special symbols or
        improperly quoted strings could cause a crash instead of
        an error message. Tests were also added to ensure the
        utilities report an error should the user:password values
        fail to parse correctly. (Bug #22780854)

      * Corrects a problem using special characters with the
        --rpl-user option. More specifically, if the user
        attempted to use a ":" (colon) in the password, the
        utility failed with an error stating that there are too
        many values to unpack. The utility will now attempt to
        use the first colon encountered for the parse (split).
        Thus, user names should not contain colons, but passwords
        may use any valid symbol (if properly quoted) including
        the colon. (Bug #22619159)

      * Corrects a problem when running mysqlbinlogpurge on a
        5.7.6 or later replication topology setup for
        multi-source replication, which could fail to detect that
        the slave is connected to the master specified if that
        master was not on the primary (first) replication
        channel. The utility now iterates through the slave
        status to check for the requested master in the list. If
        not found, the original error(s) are generated, otherwise
        the master is matched to one of the replication channels,
        and progress continues. (Bug #22543517)

      * Corrects an issue when exporting tables with bit fields
        in SQL format, where bit fields were being exported as
        strings instead of being encoded, like b'???'. Export now
        correctly formats the SQL statements in the output to
        properly handle bit fields. (Bug #22495193, Bug #79837)

      * Installation packaging code was modified to function with
        Mac OS X 10.11 (El Capitan). Installation no longer
        fails, and users can now install MySQL Utilities on El
        Capitan. (Bug #22393353, Bug #79700)

      * Corrects a problem with mysqluc where pressing the delete
        key failed to position the cursor in the correct
        location. The cursor location is now fixed, and the
        delete and arrow keys work properly. (Bug #22076859, Bug
        #78893)

      * Removed the "CREATE database" statement from the diff
        output for mysqldiff and mysqldbcompare for cases where
        the database name is the only difference. That is, the
        different output should not show a difference when
        comparing db1 to db2 when the only difference is the name
        of the database. However, the difference is shown for
        differences in quote usage and if decorators differ, such
        as the character set. (Bug #21222808, Bug #77058)

      * Corrected an issue when copying users that were created
        with the "IDENTIFIED WITH" authentication plugin option.
        The utility would copy the user, but not copy the
        authentication plugin setting, making it impossible to
        copy users with the plugin. The utility now captures the
        plugin name and assigns it to the new user. An error is
        thrown if the plugin is not on the destination machine or
        is inactive. A warning is also issued if the user
        attempts to assign a password to a new user when the
        source user has an authentication plugin. In this case,
        the utility will use the password and not the
        authentication plugin for the new user. (Bug #17666275,
        Bug #70745)
