Barry Lind	fe2dec75a9	Enhancements to how queries with bind values are stored internally and sent to ... the server. Previously we allocated a new String object for the entire final query we were sending to the database. If you had a big query, or especially if you had large bind values you ended up with essentially two copies in memory. This change will reuse the existing objects and therefore should take 1/2 the memory it does today for a given query. This restructuring will also allow in the future the ability to stream bytea data to the server instead of the current approach of pulling it all into memory. I also fixed a test that was failing on a 7.2 database. Also renamed some internal variables and some minor cleanup.

Barry Lind	8d600a7d1f	Second phase of restructuring to add jdbc3 support.	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
