Web Feb 14 17:29:00 GMT 2001 peter@retep.org.uk - Fixed bug in LargeObject & BlobOutputStream where the stream's output was not flushed when either the stream or the blob were closed. - Fixed PreparedStatement.setBinaryStream() where it ignored the length Tue Feb 13 16:33:00 GMT 2001 peter@retep.org.uk - More TestCases implemented. Refined the test suite api's. - Removed need for SimpleDateFormat in ResultSet.getDate() improving performance. - Rewrote ResultSet.getTime() so that it uses JDK api's better. Tue Feb 13 10:25:00 GMT 2001 peter@retep.org.uk - Added MiscTest to hold reported problems from users. - Fixed PGMoney. - JBuilder4/JDBCExplorer now works with Money fields. Patched Field & ResultSet (lots of methods) for this one. Also changed cash/money to return type DOUBLE not DECIMAL. This broke JBuilder as zero scale BigDecimal's can't have decimal places! - When a Statement is reused, the previous ResultSet is now closed. - Removed deprecated call in ResultSet.getTime() Thu Feb 08 18:53:00 GMT 2001 peter@retep.org.uk - Changed a couple of settings in DatabaseMetaData where 7.1 now supports those features - Implemented the DatabaseMetaData TestCase. Wed Feb 07 18:06:00 GMT 2001 peter@retep.org.uk - Added comment to Connection.isClosed() explaining why we deviate from the JDBC2 specification. - Fixed bug where the Isolation Level is lost while in autocommit mode. - Fixed bug where several calls to getTransactionIsolationLevel() returned the first call's result. Tue Feb 06 19:00:00 GMT 2001 peter@retep.org.uk - Completed first two TestCase's for the test suite. JUnit is now recognised by ant. Wed Jan 31 08:46:00 GMT 2001 peter@retep.org.uk - Some minor additions to Statement to make our own extensions more portable. - Statement.close() will now call ResultSet.close() rather than just dissasociating with it. Tue Jan 30 22:24:00 GMT 2001 peter@retep.org.uk - Fixed bug where Statement.setMaxRows() was a global setting. Now limited to just itself. - Changed LargeObject.read(byte[],int,int) to return the actual number of bytes read (used to be void). - LargeObject now supports InputStream's! - PreparedStatement.setBinaryStream() now works! - ResultSet.getBinaryStream() now returns an InputStream that doesn't copy the blob into memory first! - Connection.isClosed() now tests to see if the connection is still alive rather than if it thinks it's alive. Thu Jan 25 09:11:00 GMT 2001 peter@retep.org.uk - Added an alternative constructor to PGSQLException so that debugging some more osteric bugs is easier. If only 1 arg is supplied and it's of type Exception, then that Exception's stacktrace is now included. Wed Jan 24 09:18:00 GMT 2001 peter@retep.org.uk - Removed the 8k limit by setting it to 64k Fri Jan 19 08:47:00 GMT 2001 peter@retep.org.uk - Applied patch submitted by John Schutz that fixed a bug with ANT's SQL functions (not needed for building but nice to have fixed). Thu Jan 18 17:30:00 GMT 2001 peter@retep.org.uk - Added new error message into errors.properties "postgresql.notsensitive" This is used by jdbc2.ResultSet when a method is called that should fetch the current value of a row from the database refreshRow() for example. - These methods no longer throw the not implemented but the new noupdate error. This is in preparation for the Updateable ResultSet support which will overide these methods by extending the existing class to implement that functionality, but needed to show something other than notimplemented: moveToCurrentRow() moveToInsertRow() rowDeleted() rowInserted() all update*() methods, except those that took the column as a String as they were already implemented to convert the String to an int. - getFetchDirection() and setFetchDirection() now throws "postgresql.notimp" as we only support one direction. The CursorResultSet will overide this when its implemented. - Created a new class under jdbc2 UpdateableResultSet which extends ResultSet and overides the relevent update methods. This allows us to implement them easily at a later date. - In jdbc2.Connection, the following methods are now implemented: createStatement(type,concurrency); getTypeMap(); setTypeMap(Map); - The JDBC2 type mapping scheme almost complete, just needs SQLInput & SQLOutput to be implemented. - Removed some Statement methods that somehow appeared in Connection. - In jdbc2.Statement() getResultSetConcurrency() getResultSetType() setResultSetConcurrency() setResultSetType() - Finally removed the old 6.5.x driver. Thu Jan 18 12:24:00 GMT 2001 peter@retep.org.uk - These methods in org.postgresql.jdbc2.ResultSet are now implemented: getBigDecimal(int) ie: without a scale (why did this get missed?) getBlob(int) getCharacterStream(int) getConcurrency() getDate(int,Calendar) getFetchDirection() getFetchSize() getTime(int,Calendar) getTimestamp(int,Calendar) getType() NB: Where int represents the column name, the associated version taking a String were already implemented by calling the int version. - These methods no longer throw the not implemented but the new noupdate error. This is in preparation for the Updateable ResultSet support which will overide these methods by extending the existing class to implement that functionality, but needed to show something other than notimplemented: cancelRowUpdates() deleteRow() - Added new error message into errors.properties "postgresql.noupdate" This is used by jdbc2.ResultSet when an update method is called and the ResultSet is not updateable. A new method notUpdateable() has been added to that class to throw this exception, keeping the binary size down. - Added new error message into errors.properties "postgresql.psqlnotimp" This is used instead of unimplemented when it's a feature in the backend that is preventing this method from being implemented. - Removed getKeysetSize() as its not part of the ResultSet API Thu Jan 18 09:46:00 GMT 2001 peter@retep.org.uk - Applied modified patch from Richard Bullington-McGuire . I had to modify it as some of the code patched now exists in different classes, and some of it actually patched obsolete code. Wed Jan 17 10:19:00 GMT 2001 peter@retep.org.uk - Updated Implementation to include both ANT & JBuilder - Updated README to reflect the changes since 7.0 - Created jdbc.jpr file which allows JBuilder to be used to edit the source. JBuilder _CAN_NOT_ be used to compile. You must use ANT for that. It's only to allow JBuilders syntax checking to improve the drivers source. Refer to Implementation for more details Wed Dec 20 16:19:00 GMT 2000 peter@retep.org.uk - Finished build.xml and updated Driver.java.in and buildDriver to match how Makefile and ANT operate. Tue Dec 19 17:30:00 GMT 2000 peter@retep.org.uk - Finally created ant build.xml file Mon Nov 20 08:12:00 GMT 2000 peter@retep.org.uk - Encoding patch to Connection by wrobell@posexperts.com.pl Tue Oct 17 15:35:00 BST 2000 petermount@maidstone.gov.uk - Changed getTimestamp() again. This time Michael Stephenson's solution looked far better than the original solution put in June. Tue Oct 10 13:12:00 BST 2000 peter@retep.org.uk - DatabaseMetaData.supportsAlterTableWithDropColumn() as psql doesn't support dropping of individual columns - Merged in some last patches. Only 1 left, which may not be compatible with jdbc1 - Merged in my old retepsql project. Makefile now includes it. Mon Oct 02 12:30:00 BST 2000 peter@retep.org.uk - Merged in byte[] array allocation changes submitted by Gunnar R|nning Mon Sep 25 14:22:00 BST 2000 peter@retep.org.uk - Removed the DriverClass kludge. Now the org.postgresql.Driver class is compiled from a template file, and now has both the connection class (ie jdbc1/jdbc2) and the current version's from Makefile.global Thu Jul 20 16:30:00 BST 2000 petermount@it.maidstone.gov.uk - Fixed DatabaseMetaData.getTableTypes() Tue Jun 06 12:00:00 BST 2000 petermount@it.maidstone.gov.uk - Added org/postgresql/DriverClass.java to the list of files removed by make clean (it's dynamically built) - Fixed Statement, so that the update count is valid when an SQL DELETE operation is done. - While fixing the update count, made it easier to get the OID of the last insert as well. Example is in example/basic.java Tue Jun 06 08:37:00 BST 2000 petermount@it.maidstone.gov.uk - Removed a hardwired 8K limit on query strings - Added some missing org.'s in Connection that prevented the use of the geometric types. Thu Jun 01 07:26:00 BST 2000 petermount@it.maidstone.gov.uk - Removed timezone in getTimestamp() methods in ResultSet. Mon May 15 22:30:00 BST 2000 peter@retep.org.uk - Fixed the message Makefile produces after compiling. It still said about the old Driver class, not the new package. Spotted by Joseph Shraibman Thu May 04 11:38:00 BST 2000 petermount@it.maidstone.gov.uk - Corrected incorrect date in CHANGELOG - Fixed the ImageViewer example Wed May 03 16:47:00 BST 2000 petermount@it.maidstone.gov.uk - Fixed the Makefile so that postgresql.jar is built everytime the jdbc1 or jdbc2 rules are called. - Fixed the threadsafe example. It had problems with autocommit Wed May 03 14:32:00 BST 2000 petermount@it.maidstone.gov.uk - Rewrote the README file (the old one was 18 months old!) - Added @deprecated tags to org.postgresql.jdbc2.ResultSet to clear some warnings issued during compilation. Wed Apr 12 22:14:00 BST 2000 peter@retep.org.uk - Implemented the JDBC2 Blob interface, and ResultSet.getBlob(). Wed Apr 12 20:20:00 BST 2000 peter@retep.org.uk - Fixed bug in ResultSet.absolute(). Negative rows are now supported. - Implemented ResultSet.relative(), afterLast(). Tue Feb 1 21:40:00 GMT 2000 peter@retep.org.uk - Finally imported the contributed javax extensions by Assaf Arkin arkin@exoffice.com Mon Jan 24 21:00:00 GMT 2000 peter@retep.org.uk - Finally introduced the 7.0 additions to the core CVS repository. - All source files are now under the org.postgresql package (previously they were under postgresql). The package lines now changed accordingly. - The Makefile was rewritten so it should now work on machines that can't handle the $( ) syntax. - Dutch translation by Arnout Kuiper (ajkuiper@wxs.nl) Mon Sep 13 23:56:00 BST 1999 peter@retep.org.uk - PG_Stream.SendChar() optimised, increased default buffer size of output stream to 8k, and introduced an 8k buffer on the input stream Sverre H Huseby - Added a finalize() method to Connection class in both drivers so that the connection to the backend is really closed. - Due to many JVM's not returning a meaningful value for java.version the decision for building the JDBC1.2 or JDBC2 driver is now a compile time option. - Replaced $$(cmd...) with `cmd...` in the Makefile. This should allow the driver to compile when using shells other than Bash. Thu Sep 9 01:18:39 MEST 1999 jens@jens.de - fixed bug in handling of DECIMAL type Wed Aug 4 00:25:18 CEST 1999 jens@jens.de - updated ResultSetMetaData.getColumnDisplaySize() to return the actual display size - updated driver to use postgresql FE/BE-protocol version 2 Mon Aug 2 03:29:35 CEST 1999 jens@jens.de - fixed bug in DatabaseMetaData.getPrimaryKeys() Sun Aug 1 18:05:42 CEST 1999 jens@jens.de - added support for getTransactionIsolation and setTransactionIsolation Sun Jun 27 12:00:00 BST 1999 - Fixed typo in postgresql.Driver that prevented compilation - Implemented getTimestamp() fix submitted by Philipp Matthias Hahn - Cleaned up some comments in Connection Wed Jun 23 06:50:00 BST 1999 - Fixed error in errors.properties where the arguments are 0 based not 1 based - Fixed bug in postgresql.Driver where exception is thrown, then intercepted rather than being passed to the calling application. - Removed the file postgresql/CallableStatement, as it's not used and really exists in the jdbc1 & jdbc2 sub packages only. Wed May 19 00:20:00 BST 1999 - Internationalisation now done. Surprising that there's 68 error messages in the driver ;-) Tue May 18 07:00:00 BST 1999 - Set the ImageViewer application to use transactions Tue May 18 00:00:00 BST 1999 - Just after committing, I realised why internationalisation isn't working. This is now fixed (in the Makefile). Mon May 17 23:40:00 BST 1999 - PG_Stream.close() now attempts to send the close connection message to the backend before closing the streams - Added batch support in the JDBC2, supplied by Yutaka Tanida - Removed the old datestyle code. Now the driver uses only ISO. - Removed some files in the postgresql directory still in CVS that were moved since 6.4.x (DatabaseMetaData.java PreparedStatement.java ResultSetMetaData.java Statement.java) - Internationalisation of the error messages is partially implemented, however it's not enabled as it only works when the jar file is _not_ used, and work needs to be done. Sun Apr 11 17:00:00 BST 1999 - getUpdateCount() now returns the actual update count (before it simply returned 1 for everything). - added some updates to example.basic so it would test the new update count code. - corrected typo in a comment in Statement.java 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
