| SUBJECT | Subject: [Hangout of NYLXS] MySQL Connector/J 5.1.42 has been released
|
Dear MySQL Users,
MySQL Connector/J 5.1.42, a maintenance release of the production 5.1
branch has been released. Connector/J is the Type-IV pure-Java JDBC
driver for MySQL.
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
and mirror sites as well as Maven-2 repositories.
MySQL Connector Java (Commercial) is already 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 5.1.42 includes the following general bug fixes and
improvements, also available in more detail on
http://dev.mysql.com/doc/relnotes/connector-j/en/news-5-1-41.html
Changes in MySQL Connector/J 5.1.42 (2017-04-28)
Version 5.1.42 is a maintenance release of the production 5.1
branch. It is suitable for use with MySQL Server versions
5.5, 5.6, and 5.7. It supports the Java Database Connectivity
(JDBC) 4.2 API.
* Functionality Added or Changed
* Bugs Fixed
Functionality Added or Changed
* A null value can now be extracted from a result set to a
class belonging to the java.time package. Before, such an
extraction resulted in a NullPointerException being
thrown. Thanks to Martin Desharnais for contributing the
code. (Bug #25250938, Bug #84189)
* Connector/J now checks that a MySQL server's SSL
certificate and the Certificate Authority (CA) that
issued it are not expired before establishing an SSL
connection with the server, even if the connection
property verifyServerCertificate is set to false. (Bug
#20515688)
* Name-value pairs contained in the connection property
sessionVariables can now be separated by either commas or
a semicolons. (Bug #17757070)
Bugs Fixed
* An invalid timezone identifier was used in
StatementRegressionTest.java of the Connector/J
testsuite. (Bug #25687718, Bug #85351)
* A mysql client failed to establish an SSL connection to
the server using the SSL certificates provided in the
Connector/J source package. It was because the
certificates have been generated with the same Common
Name. This fix corrects the Common Names and regenerates
the SSL certificates. (Bug #25636947)
* The unit test testsuite.simple.ResultSetTest.testPadding
failed with the error Unknown character set: 'gb18030'
after the collation map updates in release 5.1.40. (Bug
#25556597)
* In a multi-host connection, query timeouts did not occur
as configured. It was because the CancelTask thread, when
trying to access the top level, virtual connection
object, ran into a race condition with the connection
monitor and then hung. With this fix, the CancelTask
thread is passed a direct reference to the underlying
physical connection, with which it can execute the
cancellation. (Bug #25490163, Bug #84783)
* CallableStatement.extractProcedureName() did not return
the correct result when the procedure name contained a
dash. This was due to an error in the stripComments()
method of the StringUtils class, which has now been
corrected. (Bug #25321524, Bug #84324)
* The ConnectionImpl.isReadOnly() method returned a
confusing error message when it could not retrieve the
read-only status of the server. The message has now been
changed to "Could not retrieve transaction read-only
status from server." (Bug #25101890, Bug #83834)
* A NullPointerException was thrown when a null boolean
value was being read from the database. (Bug #25048406,
Bug #83662)
* After a BIT value had been retrieved from a result set,
the wasNull() method of the result set returned value for
the last wasNull() query instead of the value for the
last retrieved column. (Bug #24841670, Bug #83368)
* Using a partially-quoted identifier (with only the
database or the procedure name quoted) or a non-existent
parameter to register an output parameter in a
CallableStatement caused a NullPointerException. With
this fix, a partially-quoted identifier is accepted, and
a non-existent parameter causes a SQLError to be thrown.
(Bug #22333996, Bug #79561)
* DatabaseMetaData.getProcedureColumns() and
DatabaseMetaData.getFunctionColumns() did not return
expected results. This was due to the errors with the
matching algorithm for the column names, which have now
been fixed. Notice that, however, the effects of the
connection parameter getProceduresReturnsFunctions on the
two methods when JDBC 4 is used remain unchanged. (Bug
#19531384, Bug #73775)
* When an UpdatableResultSet was used, trying to close the
result set and its prepared statement simultaneously by
different threads might result in a deadlock. This fix
updates the synchronization mechanism for
UpdatableResultSet to avoid the issue. (Bug #17653733,
Bug #70704)
* After a connection had already switched catalog with
setCatalog(), cached data from the old catalog was
returned for a reused server-side prepared statement.
With this fix, the cache of a server-side prepared
statement cache now includes the catalog in its key to
avoid wrong cache hits when the statement is reused on
another catalog. (Bug #16714868, Bug #66430)
