Mon Jan 25 19:45:00 GMT 1999 - created subfolders example/corba and example/corba/idl to hold the new example showing how to hook CORBA and PostgreSQL via JDBC - implemented some JDBC2 methods curtesy of Joachim.Gabler@t-online.de Sat Jan 23 10:30:00 GMT 1999 - Changed imports in postgresql.jdbc1.ResultSetMetaData as for some reason it didn't want to compile under jdk1.1.6 Tue Dec 29 15:45:00 GMT 1998 - Refreshed the README (which was way out of date) Tue Dec 29 15:45:00 GMT 1998 - Finished adding the additional methods into the JDBC2 driver. - Had to add some explicit package references for the JDK1.2 Javac to cope with the driver Tue Dec 29 12:40:00 GMT 1998 - Fixed package imports and some references to java.sql.ResultSet in various files. Compiled and tested the JDBC1 driver. Mon Dec 28 19:01:37 GMT 1998 - created a new package postgresql.jdbc2 which will contain the JDBC 2 specific classes. A similar new package (postgresql.jdbc1) has been created to hold the JDBC 1 specific classes. - modified Makefile to allow compilation of the JDBC 1 & 2 drivers, with the possibility of building a dual-spec driver. - changed the version number in postgresql.Driver to 6.5 - modified postgresql.Driver class to initiate the correct driver when used under a 1.1 or 1.2+ JVM. - postgresql.Connection and postgresql.jdbc2.Connection now extends the new class postgresql.ConnectionStub, which allows us to dynamically open the JDBC1 or JDBC2 drivers. - enabled compilation of the driver under Win32 when using the Make from the CygWin package (Cygnus B20.1 was used). - To make future development easier (now we have 2 specifications to work with) the following classes have moved from the postgresql to the postgresql.jdbc1 package: CallableStatement Connection DatabaseMetaData PreparedStatement ResultSet ResultSetMetaData Statement Some of these classes have common code that is not dependent on either JDBC specification. These common code are still in the postgresql package. Ie: postgresql.jdbc1.Connection extends postgresql.Connection and postgresql.jdbc2.Connection extends postgresql.Connection 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 - Added fix to DatabaseMetaData.getColumns() to handle patterns submitted by Stefan Andreasen - 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 - 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
