The Apache Commons DBCP team is pleased to announce the release of Apache
Apache Commons DBCP 2.2.0.
Apache Commons DBCP software implements Database Connection Pooling.
This is a minor release, including bug fixes and enhancements.
Changes in this version include:
New features:
o DBCP-451: Add constructor DriverManagerConnectionFactory(String).
o DBCP-462: Refactoring to prepare for a future patch to enable pooling of
all
prepared and callable statements in PoolingConnection. Thanks
to Keiichi Fujino.
o DBCP-458: Make it simpler to extend BasicDataSource to allow sub-classes
to
provide custom GenericObjectPool implementations. Thanks to
Adrian Tarau.
o DBCP-474: Enable pooling of all prepared and callable statements
inPoolingConnection. Thanks to Keiichi Fujino.
Fixed Bugs:
o DBCP-481: Update Apache Commons Pool from 2.4.2 to 2.5.0. Thanks to Gary
Gregory.
o DBCP-454: OSGi declarations contain multiple import headers for
javax.transaction. Thanks to Philipp Marx, Matt Sicker.
o DBCP-478: Wrong parameter name in site documentation for BasicDataSource
Configuration Parameters. Thanks to nicola mele.
o DBCP-452: Add jmxName to properties set by BasicDataSourceFactory. This
enables container-managed pools created from JNDI Resource
definitions to enable JMX by supplying a valid root JMX name.
o DBCP-446: NullPointerException thrown when calling
ManagedConnection.isClosed(). Thanks to Gary Gregory, feng yang, Euclides
M, Phil Steitz.
o DBCP-444: InvalidateConnection can result in closed connection returned
by getConnection.
o DBCP-449: Complete the fix for DBCP-418, enabling PoolableConnection
class to load in environments
(such as GAE) where the JMX ManagementFactory is not
available. Thanks to Grzegorz D.
o DBCP-455: Ensure that the cacheState setting is used when statement
pooling is
disabled. Thanks to Kyohei Nakamura.
o DBCP-453: Ensure that setSoftMinEvictableIdleTimeMillis is used when
working with
BasicDataSource. Thanks to Philipp Marx.
o DBCP-456: Correct the name of the configuration attribute
softMinEvictableIdleTimeMillis. Thanks to Kyohei Nakamura.
o DBCP-472: Avoid potential infinite loops when checking if an
SQLException is fatal
for a connection or not.
o DBCP-468: Expand the fail-fast for fatal connection errors feature to
include
managed connections.
o DBCP-463: Correct a typo in the method name
PoolableConnectionFactory#setMaxOpenPreparedStatements. The
old method
remains but is deprecated so not to break clients currently
using the
incorrect name.
o DBCP-459: Ensure that a thread's interrupt status is visible to the
caller if the
thread is interrupted during a call to
PoolingDataSource.getConnection().
o DBCP-457: When using a BasicDataSource, pass changes related to the
handling of
abandoned connections to the underlying pool so that the pool
configuration may be updated dynamically.
