- Fix for Bug#69506, XAER_DUPID error code is not returned when a duplicate XID is offered in Java.
- Added support for multi-master replication topographies in ReplicationDriver. ReplicationDriver now uses two discrete load-balanced
connections, one each for master and slave connections. The same load-balancing options which apply to load-balanced connections
now also apply to ReplicationConnections. By default, this means that when a ReplicationConnection uses master connections
(because the read-only property of the Connection is false), work may be re-balanced between configured master hosts at transaction
boundaries. As with load-balanced connections, the ReplicationConnection host list may be managed within the JVM (see
com.mysql.jdbc.ReplicationConnectionGroupManager) or optionally via JMX (using replicationEnableJMX configuration option; see
com.mysql.jdbc.jmx.ReplicationGroupManagerMBean). To specify multi-master replication topographies, define each host "type"
property using the following format:
address=(host=hostname)(port=3306)(type=[master|slave])
In the absense of explicit type definitions, the driver will assume a single master listed first, with all subsequently-listed
hosts configured as slaves.

08-05-13 - Version 5.1.26
- Fix for Bug#69298 (16845965), Methods DatabaseMetaData.getProcedures() and DatabaseMetaData.getProcedureColumns(), in JDBC4,
return stored procedure only or both stored procedures and functions metadata information, depending on the value set in the
connection property "getProceduresReturnsFunctions", having default value 'true'. Several fixes in Functions and
Procedures metadata so that consulting I__S and MySQL/DDL returns the same info.
- Fix for Bug#69308 (16879267), Avoid calling batchedStatement.close() twice, and thus raising and ignoring an undercover SQLException, in methods
PreparedStatement.executeBatchedInserts and PreparedStatement.executePreparedBatchAsMultiStatement.
- Fix for Bug#68400, useCompression=true and connect to server, zip native method cause out of memory.
CompressedInputStream now does not keep reference to connection.
Thank Dominic Tootell for his investigation, proposed solution and all the help he provided.
- Fix for Bug#65871, DatabaseMetaData.getColumns() throws an MySQLSyntaxErrorException.
Delimited names of databases and tables are handled correctly now. The edge case is ANSI quoted
identifiers with leading and trailing "`" symbols, for example CREATE DATABASE "`dbname`". Methods
like DatabaseMetaData.getColumns() allow parameters passed both in unquoted and quoted form,
quoted form is not JDBC-compliant but used by third party tools. So when you pass the indentifier
"`dbname`" in unquoted form (`dbname`) driver handles it as quoted by "`" symbol. To handle such
identifiers correctly a new behavior was added to pedantic mode (connection property pedantic=true),
now if it set to true methods like DatabaseMetaData.getColumns() treat all parameters as unquoted.
- Fix for Bug#45757 (11754192), Don't allow updateRow() to be called when updatable cursor is positioned on insert row.
- Fix for Bug#68098 (16224299), Return indexes sorted by NON_UNIQUE, TYPE, INDEX_NAME, and ORDINAL_POSITION in DatabaseMetaData.getIndexInfo.

- Fix for Bug#16426462, SyntaxRegressionTest failing on C/J 5.1.24 against MySQL 5.6.10
- Fix for Bug#60816, Cannot pass NULL to an INOUT procedure parameter.
- Added support for Connection Attributes when used with MySQL Server versions (5.6+) which support this feature.
By default, the following standard attributes are sent to the server, where they can be seen in the
performance_schema.session_connect_attrs table:
* _client_version : the version of MySQL Connector Java in use
* _client_name : "MySQL Connector Java"
* _runtime_version : the version of the Java runtime environment in which the driver is running
* _runtime_vendor : the name of company which produced the Java runtime environment
Additionally, users may supply their own key/value attributes to be exposed by providing them in
"key1:value1,key2:value2" format in the connectionAttributes connection property.
To avoid sending any connection attributes to the server, set connectionAttributes property to "none".

- Fix for Bug#64204, ResultSet.close hangs if streaming query is killed.
- Fix for Bug#16224249, Deadlock on concurrently used LoadBalancedMySQLConnection:
1) abortInternal() method was moved from com.mysql.jdbc.MySQLConnection to com.mysql.jdbc.Connection interface;
2) load-balanced/failover proxy now broadcasts abortInternal() to all underlying physical connections;
3) load-balanced/failover proxy now prevents picking of new physical connection after close() or abortInternal() were called explicitly on proxy;
4) connection synchronization mutex was refactored, now mutex is proxy instance for proxied connection or connection instance itself if there is no proxy.
- Fix for Bug#64805, StatementImpl$CancelTask occasionally throws NullPointerExceptions.
- Fixed typos in descriptions of properties.
- Fix for Bug#68011, Invalid error message noDatetimeSync property instead of noDatetimeStringSync.
02-04-13 - Version 5.1.23
- Fix for Bug#35653, executeQuery() in Statement.java let "TRUNCATE" queries being executed. "TRUNCATE" and "RENAME" are now filtered for executeQuery().
- Fix for Bug#65909, referenceThread causes memory leak in Tomcat.
Abandoned connection cleanup thread was refactored to have static shutdown method.
If you encountered this leak problem, your application should implement context listener with
AbandonedConnectionCleanupThread.shutdown() call in contextDestroyed method.
For example:
@WebListener
public class YourThreadsListener implements ServletContextListener {
public void contextDestroyed(ServletContextEvent arg0) {
try {
AbandonedConnectionCleanupThread.shutdown();
} catch (InterruptedException e) {
}
}
...
}
Note that if container does not support annotations you should add description to web.xml:
<listener>
<listener-class>user.package.YourThreadsListener</listener-class>
</listener>
- Added tests for explicit partition selection syntax introduced in 5.6GA.
- Added support of password expiration protocol. This introduces new boolean connection property disconnectOnExpiredPasswords.
If disconnectOnExpiredPasswords = true and password expired then connection will be rejected by server with ErrorCode == 1820 (ER_MUST_CHANGE_PASSWORD).
If disconnectOnExpiredPasswords = false then connection will enter to "sandbox" mode,
all commands except SET PASSWORD = ... and SET PASSWORD FOR CURRRENT_USER() = ... will cause an error to be thrown.
- Added tests for EXCHANGE PARTITION syntax introduced in 5.6GA.
- Added tests for transportable tablespaces syntax introduced in 5.6GA.
- Added tests for CREATE TABLE syntax changed in 5.6GA: CREATE TABLE ... DATA DIRECTORY = 'absolute/path/to/directory/'
- Added tests for ALTER TABLE syntax changed in 5.6GA: ALGORITHM and LOCK keywords.
- Fix for Bug#67954, stack trace used for point-of-origin in log and exception messages
causes permgen leak with webapp classloader on application redeploy. We no longer store the entire
stack trace, only the calling class and method, and even then, that only when using the usage advisor
or when profiling.
- Fix for Bug#11237, useCompression=true and LOAD DATA LOCAL INFILE SQL Command.
- Static charset/collation maps were updated.
- Fix for Bug#14260352, difference in Timestamp value returned with rewriteBatchedStatements=true.
- Fix for Bug#60598, nativeSQL() truncates fractional seconds.
- Fix for Bug#40279, Timestamp values get truncated when passed as prepared statement parameters.
This was partly fixed in 5.1.19 but that fix did not cover useLegacyDatetimeCode=true case.
- Fix for Bug#14665141, Diff results returned from ResultSet and CachedRowSet with new password hashing.
Test suite modified to don't perform comparison of PASSWORD() results if old_passwords=2
because with SHA-256 password hashing enabled they are nondeterministic.
- The driver now allows the mechanism for caching MySQL server configuration values replaceable at runtime,
via the "serverConfigCacheFactory" property. The default is an implementation that is a per-VM concurrent
map, keyed by URL. The driver will invalidate cache entries when SQLExceptions that indicate communications
errors are thrown (on the assumption that the server has been or is restarting), or if the server version
that is being connected to, differs from the one that was present when the cached values were populated.
To replace the default implementation, implement CacheAdapterFactory<String, Map<String, String>>, and
use the fully-qualified class name of this implementation for "serverConfigCacheFactory".
- Connection.setReadOnly() will take advantage of server-side support for read-only transactions
present in MySQL-5.6 and newer. Calling .isReadOnly() will incur a round-trip if useLocalSessionState
is not enabled.
09-06-12 - Version 5.1.22
- Fix for Bug#57662, Incorrect Query Duration When useNanosForElapsedTime Enabled.
- Fix for Bug#65503, ResultSets created by PreparedStatement.getGeneratedKeys() are not close()d.
- Fix for Bug#63800, getVersionColumns() does not return timestamp fields; always empty.
Added support of ON UPDATE CURRENT_TIMESTAMP for TIMESTAMP and DATETIME fields.
- Fix for Bug#41752, Can't connect mysqld which character_set_server=ucs2.
- Fix for Bug#65508, getCharsetNameForIndex() should be faster.
- Fix for Bug#14563127, Load-balanced connection fails to select valid host, closes connection
on re-balance.
07-05-12 - Version 5.1.21
- Added new built-in authentication plugin com.mysql.jdbc.authentication.Sha256PasswordPlugin
("sha256_password").
- Fix for Bug#64731, StringUtils.getBytesWrapped throws StringIndexOutOfBoundsException.
- Added new built-in authentication plugin com.mysql.jdbc.authentication.MysqlClearPasswordPlugin
("mysql_clear_password"). It allows C/J based clients to connect to MySQL accounts which use
PAM authentication for example. SSL connection required for this authentication method.
If SSL is not enabled then authentication which requires "mysql_clear_password" will lead to an error.
- Fix for Bug#13980303, Auth plugin's confidentiality requirements are not checked after Auth Switch Request.
- Fix for Bug#64205, Connected through Connector/J 5.1 to MySQL 5.5, the error message is garbled.
- Fix for Bug#37931, Null Pointer Exception Thrown When specifying invalid character_set_results enc.
- Fix for Bug#36662, TimeUtil.java: MEST mapping n/a.
- Fix a scalability/memory footprint issue where Object.finalize() was being used on
ConnectionImpl to clean up the low-level network connection to MySQL should a
connection be abandoned by the application before being cleanly close()d. We now
track connections in a phantom reference queue, and have a single thread per-vm
clean these up when the VM notices the connection is no longer referenced by
anything else.
- Added the ability to add new client-side prepared statement parse info caches by
implementing com.mysql.jdbc.CacheAdapterFactory and telling the driver to use it
when "cachePrepStmts=true" via the "parseInfoCacheFactory" configuration property.
- Implemented JDBC-4.1 methods from Java-7:
- Connection.setSchema(String) - no-op, until we support database==schema in the driver
- Connection.getSchema() - see above
- Connection.abort(Executor executor)
- Connection.setNetworkTimeout(Executor, int)
- Connection.getNetworkTimeout() throws SQLException;
- CallableStatement.getObject(int, Class<T>)
- CallableStatement.getObject(String, Class<T>)
- DBMD.getPseudoColumns() - returns an empty result set
- DBMD.generatedKeyAlwaysReturned() - always true for MySQL
- ResultSet.getObject(int, Class<T>)
- ResultSet.getObject(String, Class<T>)
- Statement.closeOnCompletion()
- Statement.isCloseOnCompletion()
05-02-12 - Version 5.1.20
- Fix for Bug#64983, 5.1.19 not working with JBoss AS 4.2.3.GA.
- Fix for Bug#13960556, java.lang.StringIndexOutOfBoundsException in com.mysql.jdbc.PreparedStatement.formatNanos(int nanos).
- Fix for pluggable authentication tests to run on Windows.
- Fix for Bug#13897714, NPE in testsuite.regression.StatementRegressionTest.testBug1933() with 5.6.5_m8 server.
- Fix for Bug#55962, Savepoint identifier is occasionally considered as floating point numbers.
- Fix for Bug#13955027, SET OPTION syntax was removed starting from 5.6.5 server version.
- Fix for Bug#13958793, ClassCastException in ConnectionImpl.buildCollationMapping() with 4.1 server.
- Fix for Bug#36478, Client prepared statement bugged if word 'limit' included in the query.
04-02-12 - Version 5.1.19
- Fix for Bug#64621, setMaxRows was not correctly processed during CS PS metadata
collection causing entire resultset to be fetched and possibly leading to OOM.
- Fix for Bug#63456, MetaData precision is different when using UTF8 or Latin1 tables.
The problem was in finding maxBytesPerChar through versioned mapping from Java charset to MySQL charset.
That map returns "utf8mb4" instead "utf8" for server versions starting with 5.5.2.
CharsetMapping, ConnectionImpl and Field have been reorganized to use static maps INDEX_TO_MYSQL_CHARSET,
STATIC_CHARSET_TO_NUM_BYTES_MAP instead. Also dynamic maps ConnectionImpl.indexToCustomMysqlCharset
and ConnectionImpl.mysqlCharsetToCustomMblen have been added for custom charsets.
- Added support for pluggable authentication via the com.mysql.jdbc.AuthenticationPlugin
interface (which extends standard "extension" interface). Examples are in
com/mysql/jdbc/authentication and in testsuite.regression.ConnectionRegressionTest.
This introduces three new properties:
authenticationPlugins defines comma-delimited list of classes that implement
com.mysql.jdbc.AuthenticationPlugin and which will be used for authentication
unless disabled by "disabledAuthenticationPlugins" property.
disabledAuthenticationPlugins defines comma-delimited list of classes implementing
com.mysql.jdbc.AuthenticationPlugin or mechanisms, i.e. "mysql_native_password".
The authentication plugins or mechanisms listed will not be used for authentication
which will fail if it requires one of them. It is an error to disable the default
authentication plugin (either the one named by "defaultAuthenticationPlugin" property
or the hard-coded one if "defaultAuthenticationPlugin" propery is not set).
defaultAuthenticationPlugin defines name of a class implementing
com.mysql.jdbc.AuthenticationPlugin which will be used as the default authentication
plugin. It is an error to use a class which is not listed in "authenticationPlugins"
nor it is one of the built-in plugins. It is an error to set as default a plugin
which was disabled with "disabledAuthenticationPlugins" property. It is an error
to set this value to null or the empty string (i.e. there must be at least a valid
default authentication plugin specified for the connection, meeting all constraints
listed above).
- Fix for Bug#63526. The problem happens in com.mysql.jdbc.EscapeProcessor#escapeSQL. The function recognizes the string in the create table statement as an escape sequence (line 136+138). The "if" construct beginning in line 182 tries to match a white-space collapsed version of the string to prefixes for valid jdbc-escapes (till line 300). Since no matching escape sequence is found and no "else" clause is defined, neither the token, nor replacement are added to the resulting escaped SQL string.
- Fix for Bug#61203, noAccessToProcedureBodies does not work anymore.
- Fix for Bug#63811, pointless Socket.bind() when using ephemeral ports and interfaces, which limits scalability on some platforms.
- Connection.changeUser() would not check for closed connections, leading to NPEs when this method was called on a closed connection.
- Fix for Bug#63284, memory leak with Failover proxied Statement/PreparedStatement with DBCP due to improper implementation of equals().
- Prepared statements would needlessly allocate a 4K buffer for converting
streams when no set*Stream() methods had been used.
10-03-11 - Version 5.1.18
- Fix for Bug#12565726, not putting the space between VALUES() and ON DUPLICATE KEY UPDATE
causes C/J a) enter rewriting the query although it has ON UPDATE
and b) to generate the wrong query with multiple ON DUPLICATE KEY
- Fix for Bug#12784170, "process fork failure" errors while running test suite via ant on Windows.
Added new ant flag, com.mysql.jdbc.junit.fork, which controls whether JUnit will fork new processes
for testing ("on", default and legacy behavior) or not ("off", required for Windows).
- Reverting changes made to ConnectionImpl.java,
private boolean characterSetNamesMatches function.
- Added function MYSQL_INDEX_TO_MYSQL_CHARSET to retrieve server charset name
using index instead of parsing variables to CharsetMapping.java.
- Completed fix for Bug#61201/12649557, fixed tests failures.
- Fix for Bug#61201/12649557, Can't establish connection when url has
sessionVariables and characterEncoding. Fix covers only MySQL server 4.1+
- Fix for Bug#61501 - Calling Statement.cancel() on a statement that isn't
currently executing will cause some later-executed query on the same
connection to be cancelled unexpectedly. The driver now guards against this
condition, but it is an underlying server issue. The MySQL statement "KILL QUERY"
(which is what the driver uses to implement Statement.cancel()) is rather
non-deterministic, and thus the use of Statement.cancel() should be avoided
if possible.
- Fix for Bug#61866/12791594 - Calling Statement.getWarnings() after
Statement.clearWarnings() has been called, returns the "old" warnings.
- Fix for Bug#13036537 - LRUCache was really a least-recently-added cache.
- Fix for Bug#13036309, Correcting parameter name in maxPerformance.properties.
07-04-11 - Version 5.1.17
- Fix for Bug#61332 - LIKE not optimized in server when run against I__S tables and no wildcards used.
Databases/tables with "_" and/or "%" in their names (escaped or not) will be handled by this code path,
although slower, since it's rare to find these characters in table names in SQL. If there's a "_" or "%"
in the string, LIKE will take care of that, otherwise we now use = . The only exception is
information_schema database which is handled separately. Patch covers both getTables() and getColumns().
- Fix for Bug#61150 - First call to stored procedure fails with "No Database Selected".
The workaround introduced in DatabaseMetaData.getCallStmtParameterTypes to fix
the bug in server where SHOW CREATE PROCEDURE was not respecting lower-case table names
is misbehaving when connection is not attached to database and on non-casesensitive OS.
- Fix for Bug#61105 - Avoid a concurrent bottleneck in Java's character set
encoding/decoding when converting bytes to/from Strings.
04-21-11 - Version 5.1.16
- Partial fix for BUG#54135 - setQueryTimeout unsafe across VIP. Fix prevents c/J from
killing the right ConnectionID but on wrong server.
- Fix for BUG#57808 - wasNull not set for DATE field with value 0000-00-00
in getDate() although zeroDateTimeBehavior is convertToNull.
- Fix for Bug#54425 - Bypassing the server protocol bug where DB should be null-terminated
whether it exists or not. Affects COM_CHANGE_USER.
- Fix for Bug#60313 (11890729), bug in
com.mysql.jdbc.ResultSetRow.getTimestampFast().
- Fix for bug 11782297, DBMD.getTables (so thus getColumns too) fails with
table names containing dot (like "junk_[Sp:e,c/ C-h+a=.r]").
- Added the ability to determine if the connection is against a server on the
same host via the Connection.isServerLocal() method.
- Fix for bug 12325877, Setting "autoReconnect=true" and
"cacheServerConfiguration=true" would cause connections created after
an existing connection fails to have non-existent values for server
variables which lead to exceeding of max allowed packet exceptions when the
new connections were used.
02-08-11 - Version 5.1.15
- Fix for Bug#38367, parameters metadata did not reflect the fact that NULL is allowed
parameter value. So DatabaseMetaData.getProcedureColumns will set isNullable member to
java.sql.DatabaseMetaData.procedureNullable now.
- Completed fix for Bug#27916.
- Fix for Bug#59224, adding 5.5 reserved words to DatabaseMetaData.getSQLKeywords().
- Fixed an issue where statement comments set via Connection.setStatementComment()
weren't represented in autoGenerateTestcaseScript=true output.
- Added ability to include the current java thread dump in the exception message
given for deadlock/wait lock timeout exceptions, enable with
"includeThreadDumpInDeadlockExceptions=true" in your JDBC url.
- Added ability to include current thread name as a statement comment visible
in MySQL's "SHOW PROCESSLIST" and Innodb deadlock diagnostics, enable with
"includeThreadNamesAsStatementComment=true".
- Added an SLF4J logging adapter. Enable by adding setting the connection
property "logger" to "Slf4JLogger" and placing the appropriate bridge
from SLF4J to the logging framework of choice in your CLASSPATH. As with
other Connector/J logging adapters, the log category name used by the
driver is "MySQL". See http://www.slf4j.org/manual.html for more details.
12-06-10 - Version 5.1.14
- Fix for Bug#58728, NPE in com.mysql.jdbc.jdbc2.optional.StatementWrappe.getResultSet()
if rs is null. Regression test case added to Statement regression tests.
- Fix for Bug#58751, DatabaseMetadata.getIndexInfo() CARDINALITY now clamped
to Integer.MAX_VALUE.
- Fix for BUG#58590
- Testsuite.Simple.DateTest, MetadataTest, NumbersTest and StatementsTest cleaned and fixed.
- Testsuite.simple, ConenctionTest & DataSourceTest are up to date. Major rework on
ConnectionTest.testDeadlockDetection (Sveta) and testUseCompress.
- Testsuite.simple, CallableStatementTest & CharsetTests are up to date.
- Testsuite.regression SubqueriesRegressionTest and StringRegressionTest are up to date.
- Testsuite.regression MicroPerformanceRegressionTest, NumbersRegressionTest, PooledConnectionRegressionTest,
ResultSetRegressionTest are up to date.
- Testsuite.regression.MetaDataRegressionTest up to date.
- Typo in StatementRegressionTest.testLikeWithBackslashes fixed. StatementRegressionTest
