Barry Lind	62da2fa0e1	Fixed DatabaseMetaData to correctly handle NAME size of 64 ...

Barry Lind	2232172e44	JDBC checkin fixing the following bugs: ... Fixed support in the driver for notifications (added PGConnection.getNotifications()) - problem reported by Benjamin.Feinstein@guardent.com Worked around server problems with int8/int2 and constants; quote values when they are intended to bind to an int8/int2 column - reported by many Fixed bug in the Array interface with string parsing not handling escaped characters correctly - reported by devajx@yahoo.com Added workaround to support 'infinity' and '-infinity' for dates - reported bydmitry@openratings.com Fixed some performance issues with setBlob - reported by d.wall@computer.org Added support for using new prepared statements functionality in 7.3 (added PGStatement.setUseServerPrepare() and isUseServerPrepare() methods) Modified Files: jdbc/org/postgresql/PGConnection.java jdbc/org/postgresql/PGStatement.java jdbc/org/postgresql/core/QueryExecutor.java jdbc/org/postgresql/jdbc1/AbstractJdbc1Connection.java jdbc/org/postgresql/jdbc1/AbstractJdbc1ResultSet.java jdbc/org/postgresql/jdbc1/AbstractJdbc1Statement.java jdbc/org/postgresql/jdbc2/AbstractJdbc2Statement.java jdbc/org/postgresql/jdbc2/Array.java Added Files: jdbc/org/postgresql/PGNotification.java jdbc/org/postgresql/core/Notification.java	24 years ago
Barry Lind	1e3187366c	Initial restructuring to add jdbc3 support. There was a significant amount ... of duplicated code between the jdbc1 and jdbc2. This checkin restructures the code so that the duplication is removed so that the jdbc3 support can be added without adding yet another copy of everything. Also many classes were renamed to avoid confusion with multiple different objects having the same name. The timestamp tests were also updated to add support for testing timestamp without time zone in addition to timestamp with time zone Modified Files: jdbc/Makefile jdbc/build.xml jdbc/example/ImageViewer.java jdbc/example/basic.java jdbc/example/blobtest.java jdbc/example/threadsafe.java jdbc/org/postgresql/Driver.java.in jdbc/org/postgresql/Field.java jdbc/org/postgresql/core/QueryExecutor.java jdbc/org/postgresql/fastpath/Fastpath.java jdbc/org/postgresql/jdbc1/CallableStatement.java jdbc/org/postgresql/jdbc1/DatabaseMetaData.java jdbc/org/postgresql/jdbc1/PreparedStatement.java jdbc/org/postgresql/jdbc2/Array.java jdbc/org/postgresql/jdbc2/CallableStatement.java jdbc/org/postgresql/jdbc2/DatabaseMetaData.java jdbc/org/postgresql/jdbc2/PreparedStatement.java jdbc/org/postgresql/jdbc2/UpdateableResultSet.java jdbc/org/postgresql/largeobject/LargeObjectManager.java jdbc/org/postgresql/largeobject/PGblob.java jdbc/org/postgresql/largeobject/PGclob.java jdbc/org/postgresql/test/jdbc2/BlobTest.java jdbc/org/postgresql/test/jdbc2/ConnectionTest.java jdbc/org/postgresql/test/jdbc2/DatabaseMetaDataTest.java jdbc/org/postgresql/test/jdbc2/TimestampTest.java jdbc/org/postgresql/test/jdbc2/UpdateableResultTest.java jdbc/org/postgresql/util/Serialize.java Added Files: jdbc/org/postgresql/PGConnection.java jdbc/org/postgresql/PGStatement.java jdbc/org/postgresql/jdbc1/AbstractJdbc1Connection.java jdbc/org/postgresql/jdbc1/AbstractJdbc1ResultSet.java jdbc/org/postgresql/jdbc1/AbstractJdbc1Statement.java jdbc/org/postgresql/jdbc1/Jdbc1Connection.java jdbc/org/postgresql/jdbc1/Jdbc1ResultSet.java jdbc/org/postgresql/jdbc1/Jdbc1Statement.java jdbc/org/postgresql/jdbc2/AbstractJdbc2Connection.java jdbc/org/postgresql/jdbc2/AbstractJdbc2ResultSet.java jdbc/org/postgresql/jdbc2/AbstractJdbc2Statement.java jdbc/org/postgresql/jdbc2/Jdbc2Connection.java jdbc/org/postgresql/jdbc2/Jdbc2ResultSet.java jdbc/org/postgresql/jdbc2/Jdbc2Statement.java Removed Files: jdbc/org/postgresql/Connection.java jdbc/org/postgresql/ResultSet.java jdbc/org/postgresql/Statement.java jdbc/org/postgresql/jdbc1/Connection.java jdbc/org/postgresql/jdbc1/ResultSet.java jdbc/org/postgresql/jdbc1/Statement.java jdbc/org/postgresql/jdbc2/Connection.java jdbc/org/postgresql/jdbc2/ResultSet.java jdbc/org/postgresql/jdbc2/Statement.java	24 years ago
Bruce Momjian	a4e3943b3f	Back out Gunnar R|nning jdbc changes.	26 years ago
Bruce Momjian	5383b5d8ed	Okay, I have some new code in place that hopefully should work better. I ... couldn't produce a full patch using cvs diff -c this time since I have created new files and anonymous cvs usage doesn't allow you to adds. I'm supplying the modified src/interfaces/jdbc as a tarball at : http://www.candleweb.no/~gunnar/projects/pgsql/postgres-jdbc-2000-10-05.tgz The new files that should be added are : ? org/postgresql/PGStatement.java ? org/postgresql/ObjectPool.java ? org/postgresql/ObjectPoolFactory.java There is now a global static pool of free byte arrays and used byte arrays connected to a statement object. This is the role of the new PGStatement class. Access to the global free array is synchronized, while we rely on the PG_Stream synchronization for the used array. My measurements show that the perfomance boost on this code is not quite as big as my last shot, but it is still an improvement. Maybe some of the difference is due to the new synchronization on the global array. I think I will look into choosing between on a connection level and global level. I have also started experimented with improving the performance of the various conversions. The problem here is ofcourse related handle the various encodings. One thing I found to speed up ResultSet.getInt() a lot was to do custom conversion on the byte array into int instead of going through the getString() to do the conversion. But I'm unsure if this is portable, can we assume that a digit never can be represented by more than one byte ? It works fine in my iso-latin-8859-1 environment, but what about other environments ? Maybe we could provide different ResultSet implementations depending on the encoding used or delegate some methods of the result set to an "converter class". Check the org/postgresql/jdbc2/FastResultSet.java in the tarball above to see the modified getInt() method. Regards, Gunnar	26 years ago
