Subject:MySQL Utilities 1.5.2 has been released
View as plain text  
Dear MySQL users,

This is the GA release for Utilities 1.5. MySQL Utilities version 1.5.2
is compatible with MySQL Server versions 5.5 and greater. Python v2.6
and v2.7 are supported.

In addition to server utilities, MySQL Utilities also contains
MySQL Fabric: a framework for managing a collection of MySQL servers.
MySQL Fabric is deployed as a separate service daemon that contains
support for high-availability and sharding. MySQL Utilities and Fabric
require Connector/Python 2.0.0 or higher.

The management framework maintains a database of the routing and
state information for the servers making up the system and provides
an easy-to-use command line interface for adding, removing and
organizing servers.

High-availability is provided by continuously monitoring the servers
and executing slave promotion when the master crashes and just as
importantly automatically updates the state and routing information
that gets messages to the right server.

MySQL Fabric comes with built-in support for sharding either using
ranges or consistent hashing and supports the sharding of multiple
tables to ensure that rows with matching sharding keys are stored
in the same shard. MySQL Fabric also contains support for global
tables that are duplicated on all shards as well as the ability to
synchronize schema updates across all of the servers.

To provide high performance and avoid latency, transactions are
directly routed by Fabric-aware connectors rather than routing via
an external proxy. The connectors dispatch transactions to the
correct shard, perform load-balancing, and handle read-write
splitting. Currently there exists Fabric-aware versions of
Connector/Python, Connector/Java, and Connector/PHP (through a
Fabric-aware mysqlnd_ms plugin).

MySQL Utilities v1.5.2 GA is available for download from

http://dev.mysql.com/downloads/tools/utilities/

A brief summary of changes is listed below. Please check the
CHANGES.txt file inside the distribution for a more complete list
of changes.

Changes in MySQL Utilities 1.5.2 (2014-09-26 General Availability)

Bugs Fixed

   * Added the missing README and LICENSE text for the commercial
     packages. (Bug #19675930)

   * For Windows, the Utilities MSI distribution package was
     setting the wrong permissions for the generated installation
     directory, which included all permissions granted for the
     'Users' group. Now, the only permission set here for the
     'Users' group is read-only. (Bug #19611879)

   * A debugging message was being sent through the Fabric RPC
     protocol. (Bug #19588383, Bug #73864)

   * Due to licensing conflicts between OpenSSL and GPL, SSL
     support is not included in the community edition for Windows.
     (Bug #19487002)

   * Fabric behaved inconsistently with respect to sharding and
     non-existent tables. (Bug #19450843, Bug #73599)

   * Separate CHANGES and README files were added to the commercial
     distribution. (Bug #19380635)

   * For Fabric, Connectors inserting large amount of data before
     the TTL expires, after a resharding metadata update, could
     cause inconsistencies between the sharding definition and the
     data on the shard. (Bug #19427027, Bug #73546)

   * Fabric could return an incorrect "lower_bound" length,
     depending on the character set. (Bug #19352961, Bug #73218)

   * The mysqlserverclone utility did not check for a low amount of
     free space before it created a new instance of the server. It
     now errors out if 120+ MB of free space is unavailable, but
     this check can be ignored by also passing in the --force
     option.
     Additionally, the error handling for failed new data directory
     creation was improved to show additional details about the
     failure. (Bug #19303700, Bug #73366)

   * The --disable-binary-logging flag of the mysqldbcompare
     utility did not function properly. It always required SUPER
     privileges in cases where the server had binary logging
     enabled, it was enabled internally even when not in use, and
     it threw an error when attempting to generate SQL statements
     for the differences between tables if one of the rows had
     columns with NULL values.
     Also, the ability to call the to_sql method for each column
     was added, which is enabled by default for the CSV output
     type. (Bug #19320164, Bug #73426)

   * When copying views that depended on sub-views that were not
     yet copied, some utilities such as mysqldbcopy failed. The
     dependency related code was fixed to solve this problem. (Bug
     #19302898, Bug #73383)

   * The policy command for the mysqlauditadmin utility failed when
     applied to recent MySQL server versions (such as MySQL 5.6.20
     and 5.7.5). This is because audit_log_policy is now a READONLY
     variable (Bug #19259597)

   * The utilities did not parse all types of GRANT statements,
     such as those with PROXY privileges and stored routines. The
     utilities could also fail when objects contained backticks.
     (Bug #19238432)

   * Commands accept either a UUID or an address (i.e. host:port)
     to specify a server. The code was ignoring that a wrong
     address could be provided, and in consequence the execution
     could hang. The address is now validated before it is used.
     If the server belongs to a group, the address is checked
     against the information stored in the state store.
     If the server is not part of a group, Fabric will try to
     access the server until a timeout is reached. The default
     value for this timeout is defined through the option
     "unreachable_timeout" in the "servers" section in the
     configuration file, and it affects the following commands:

        + server lookup_uuid address [--timeout=NONE] ...

        + server clone group_id destn_address [--timeout=NONE] ...

        + group add group_id address [--timeout=NONE] ...
     (Bug #19172889, Bug #73233)

   * The mysqldbcompare utility failed when comparing two databases
     while using the SQL difftype. (Bug #19174364, Bug #72181)

   * Some of try/exception blocks were catching the DatabaseError
     exception and raising a new exception without propagating
     information from the original problem.
     The error messages were improved by adding information about
     the server where the error originated, and the caught
     DatabaseError information is merged into the appropriate
     objects. (Bug #18999358, Bug #18370950, Bug #73019)

   * The --force option was removed from the mysqlfabric utility.
     It was removed to help alleviate confusion about its purpose.
     Its functionality was replaced by clearer status messages that
     are always printed out. (Bug #18991971, Bug #72931)

   * The --skip-innodb option is used by the utilities, but this
     option is ignored in MySQL 5.7+. A warning is now issued for
     this scenario. (Bug #18753983, Bug #72633)

   * The mysqldiff utility's --skip-table-options option would fail
     when comparing two tables with different column ordering, or
     when also setting the --difftype option to SQL. (Bug
     #18632836, Bug #72178)

   * The RPM installation failed to check for the required
     Connector/Python version, and having the incorrect version
     installed caused "mysqlfabric manage setup" to fail. (Bug
     #18450008)
