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

    * 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)
