- Web Oct 7 22:00:00 BST 1998
- - removed syncronised from Connection.ExecSQL(). See next entry.
- - added new syncronised locking in the Connection.ExecSQL() and
- FastPath.fastpath() methods. They now lock against the PG_Steam
- object for the connection, which now provides full Thread Safety.
- - Reposted ChangeLog as it's missing from CVS.
-
- Modifications done since 6.3.2 was released and Sun Aug 30 11:33:06 BST 1998
- - Fixed PreparedStatement.setObject as it didn't handle shorts
- - ResultSet.getDate() now handles null dates (returns null ratrher
- than a NullPointerException)
- - ResultSetMetaData.getPrecision() new returns 0 for VARCHAR
- - Field now caches the typename->oid in a Hashtable to speed things
- up. It removes the need for some unnecessary queries to the backend.
- - PreparedStatement.toString() now returns the SQL statement that it
- will send to the backend. Before it did nothing.
- - DatabaseMetaData.getTypeInfo() now does something.
- - Connection now throws an exception if either of the user or password
- properties are missing, as they are required for JDBC to work.
- This occasionally occurs when the client uses the properties version
- of getConnection(), and is a common question on the email lists.
-
- Sun Aug 30 11:33:06 BST 1998
- - Created ChangeLog file, and entered stuff done since 6.3.2 and today
- - Change version number to 6.4 in Driver.java
- - Added fix to DatabaseMetaData.getTables() submitted by
- Stefan Andreasen <stefan@linux.kapow.dk>
- - Added fix to DatabaseMetaData.getColumns() to handle patterns
- submitted by Stefan Andreasen <stefan@linux.kapow.dk>
- - Set TcpNoDelay on the connection, as this gives us a 10x speed
- improvement on FreeBSD (caused by a bug in their TCP Stack). They
- should fix the bug before 6.4 is released, but will keep this
- in here unless it causes more problems.
- Submitted by Jason Venner <jason@idiom.com>
- - Removed a duplicate definition of fieldCache
- - Added a more meaningful message when the connection is refused. It
- now says:
- Connection refused. Check that the hostname and port is
- correct, and that the postmaster is running with the -i flag,
- which enables TCP/IP networking.
- - Removed kludge in PreparedStatement.setDate() that acted as a
- temporary fix to a bug in SimpleDateFormat, as it broke date
- handling in JDK 1.1.6.
- - Modified PG_Stream and Connection, so that outbound data is now
- buffered. This should give us a speed improvement, and reduce the
- ammount of network packets generated.
- - Removed duplicate code and optimised PG_Stream.
- - PG_Stream now returns a more meaningful message when the connection
- is broken by the backend. It now returns:
- The backend has broken the connection. Possibly the action you
- have attempted has caused it to close.
- - Removed obsolete code from Connection.
- - The error message returned when the authentication scheme is unknown
- has been extended. It now reads:
- Authentication type ### not supported. Check that you have
- configured the pg_hba.conf file to include the client's IP
- address or Subnet, and is using a supported authentication
- scheme.
- - Connection.getMetaData() now caches the instance returned, so
- multiple calls will return the same instance.
- - Created a test application that tests the DatabaseMetaData and
- ResultSetMetaData classes.
- - Replaced getString(#).getBytes() with getBytes(#) which should speed
- things up, and reduce memory useage.
- - Optimised DatabaseMetaData.getProcedures(), and implemented patterns
- - Fixed NullPointerExceptions thrown when a field is null (Internal
- to the driver, not caused by results from the backend.
- DatabaseMetaData.getProcedures() is an example of a method that
- causes this):
- - ResultSetMetaData.getColumnName() now returns field# where
- # is the column name.
- - ResultSet.getObject() fixed
- - Fixed bug in psql example that was affected by null fields
- - DatabaseMetaData.getTables()
- - DatabaseMetaData.getPrimaryKeys() ran a query with an ambiguous field
- fixed.
- - getTypeInfo() optimised to increase speed and reduce memory useage
- - ResultSetMetaData.isCurrency() optimised and is now smaller.
- - Removed unnecessary code fromResultSetMetaData.getCatalogName()
- and getSchemaName().
- - Created new class postgresql.util.PGmoney to map the money type
- - Created new class postgresql.geometric.PGline to map the line type
-
