Changes in MySQL Connector/J 5.1.28 (2013-12-23)

Version 5.1.28 is a maintenance release of the production 5.1 branch. It is suitable for use with many MySQL server versions, including 4.1, 5.0, 5.1, 5.4, 5.5 and 5.6.

Functionality Added or Changed

  • Added support for live management for replication hosts. This enables users to change replication topographies (for example, adding or removing a host, or promoting a salve to master) without having to restart an application. See Live Reconfiguration of Replication Topography for details. (Bug #70842)

Bugs Fixed

  • A shadow declaration of com.mysql.jdbc.OperationNotSupportedException is removed from com.mysql.jdbc.RowDataDynamic. (Bug #17833137, Bug #70969)

  • An incorrect SQLException subclass was thrown during a query interruption. This fix creates a new, JDBC4-specific version of MySQLQueryInterruptedException, which subclasses MySQLNonTransientException. (Bug #17750877, Bug #70835)

  • A validation is added to check if blobSendChunkSize is negative (which is the case when maxAllowedPacket is set with a value less than or equal to 8203) when useServerPrepStmts=true. It throws an exception when the validation fails. (Bug #17184082, Bug #69777)

  • When the connection property dontTrackOpenResources=true was used, the result set was closed after a Statement.close() was issued. (Bug #17164058, Bug #69746)

  • The timeout limit set by DriverManager.setLoginTimeout() was not honored during a handshake attempt. This fix adds the DriverManager.setLoginTimeout() control to the function NonRegisteringDriver.connect(): if the defined timeout is reached, the connection creation is cancelled and an exception is thrown. (Bug #17015317, Bug #69579)

  • The method Statement.closeOnCompletion() was not working. (Bug #16691047, Bug #68916)

  • With cacheResultSetMetadata=true, cacheCallableStmts=true, and cachePrepStmts=true, if a stored procedure that returns a result set was called, calling the stored procedure a second time resulted in a null pointer exception being thrown for initializeResultsMetadataFromCache. (Bug #11762713, Bug #55340)

  • Connector/J's SQL escape sequence processor was confused by multiple backslashes. The EscapeTokenizer has been re-factored to process multiple backslashes properly. (Bug #11759035, Bug #51313)
