Subject:MySQL Connector/J 5.1.37 has been released
View as plain text  
Hello all,

MySQL Connector Java 5.1.37, a maintenance release of the production 5.1
branch, has been released. Connector/J is a Type-IV pure-Java JDBC
driver for MySQL. It is suitable for use with MySQL server versions 5.5,
5.6, and 5.7. It is also the first release of MySQL Connector/J to support
the Java Database Connectivity (JDBC) 4.2 API.

MySQL Connector Java is available in source and binary form from the
Connector/J download pages at
http://dev.mysql.com/downloads/connector/j/5.1.html

MySQL Connector Java (Commercial) is available for download on the My
Oracle Support (MOS) website. This release will be available on
eDelivery (OSDC) in next month's upload cycle.

As always, we recommend that you check the "CHANGES" file in the
download archive to be aware of changes in behavior that might affect
your application.

MySQL Connector/J 5.1.37 includes the following general bug fixes and
improvements, also available in more detail on
http://dev.mysql.com/doc/relnotes/connector-j/en/news-5-1-37.html :

Changes in MySQL Connector/J 5.1.37 (2015-10-15)

Functionality Added or Changed

   * Connector/J now supports the JSON data type, which has
     been supported by the MySQL server since release 5.7.8.

   * methodCompressedInputStream.getNextPacketFromServer() has
     been refactored to reduce memory use and garbage
     collection efforts caused by the use of the inflater.
     (Bug #21648826, Bug #78106)

   * The code for executing a REPLACE statement when
     rewriteBatchedStatements=true has been refactored by
     putting multiple batched statements into a single query,
     making it work more like an INSERT statement. This
     increases the efficiency for running REPLACE statements.
     Thanks to Jie Han for contributing the code. (Bug
     #21429909, Bug #77681)

   * A new connection property,
     truncateFractionalSeconds=true|false, has been
     introduced. It controls whether fractional seconds in
     timestamps are to be truncated on the client side or to
     be sent to the server side for truncation there. See the
     entry for the new property in Driver/Datasource Class
     Names, URL Syntax and Configuration Properties for
     Connector/J
     (http://dev.mysql.com/doc/connector-j/en/connector-j-refe
     rence-configuration-properties.html) for details. Thanks
     to Kwon Nam Son for contributing the code. (Bug
     #21304726, Bug #77449)

   * A new connection property, enableEscapeProcessing, has
     been introduced for supporting JDBC 4.2. It sets the
     default escape processing behavior for Statement objects.
     See the entry for the new property in Driver/Datasource
     Class Names, URL Syntax and Configuration Properties for
     Connector/J
     (http://dev.mysql.com/doc/connector-j/en/connector-j-refe
     rence-configuration-properties.html) for details.

Bugs Fixed

   * A ClassCastException resulted for a Fabric connection
     when rewriteBatchedStatements was "true" and a batch
     update was rewritten. (Bug #21876798)

   * A number of regression tests in the testsuite failed when
     they were run against MySQL 5.7, because the
     NO_AUTO_CREATE_USER SQL mode had become the default
     behavior of the server since MySQL 5.7.7, making some
     GRANT statements in the test fail when a new user had to
     be created. With this fix, CREATE USER statements have
     been added to the regressions tests when needed, to
     prevent the test failures. (Bug #21697684, Bug #78225)

   * Connecting to MySQL 5.0 and 5.1 using Connector/J 5.1.36
     resulted in an SQLException, with a complaint for an
     "Unknown system variable 'language'". (Bug #21415165, Bug
     #77665)

   * The IS_GENERATEDCOLUMN field was empty in the result
     returned by DatabaseMetaData.getColumns(). This fix
     corrects the field so that it contains a YES or NO
     according to whether the column is generated or not. (Bug
     #20969312, Bug #76859)

   * getTypeInfo() returned an incorrect PRECISION value of
     "255" for the data type of VARCHAR. The return value has
     been corrected to "65535." (Bug #20675539, Bug #76187)

   * When a connection is forcefully closed with
     abortInternal() in the ConnectionImpl class, a null point
     exception sometimes resulted. This is now avoided by
     putting the associated this.io.releaseResources() call
     inside a try block, so that the exception, unavoidable
     due to a race condition, can be properly caught and
     ignored. (Bug #20536592, Bug #75849)

   * If the MySQL server's default authentication method was
     SHA256 but neither one of the Connector/J connection
     properties allowPublicKeyRetrieval and
     serverRSAPublicKeyFile was set, the authentication failed
     with a TransientConnectionException, complaining that the
     public key could not be retrieved. With this fix,
     authentication continues in the situation, allowing other
     enabled authentication methods to be tried. (Bug
     #20433047, Bug #75670)

   * When a lock wait timeout occurred, an SQLException was
     thrown while an SQLTransientException should be thrown
     instead. It was due to a wrong SQLState number used in
     the code, which has now been fixed. (Bug #16634180)

   * When the time zone on the MySQL server was configured to
     "GMT" but the client was in a different time zone,
     Connector/J would make wrong adjustments for event
     timestamps when working with the server. (Bug #11758179,
     Bug #50348)
