Thread: ConnectionPoolDataSource submittal
Folks-
I finished an implementation of the ConnectionPoolDataSource that is
functional. I've included in this email the relavant code (tar, gziped):
org/postgresql/PostgresqlConnectionPoolDataSource.java
org/postgresql/psqlProps.properties
org/postgresql/util/DefaultProperties.java
org/postgresql/jdbc2/PostgresqlPooledConnection.java
(What is the normal way to send in new files for the driver? Is attachment
prefered?) They are also on my website at
http://members.home.net/wolpert5/code/
as well. The only additions left to make is
1) Cleaning thread to close unused connections
2) Wrap objects returned by the connection so errors are caught on that
level too.
3) Move all exceptions to throw PSQLException rather than SQLException.
(So they'll use the errors.properties file instead of being hard
coded.)
I'll do these if people like the code I've submitted. The code should
function properly, and is fully commented in the relavent areas. The
DefaultProperties.java class I submited has also been updated; it nolonger
throws exceptions due to read errors, and does not synchronize access to
itself. Please comment on my submittial, and if I'm going about my
updates
correctly. (And if you have improvements for my code. :-)
Thanks

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Whoops. Sorry about that. I accidently resent my original message. (Didn't mean to spam the list.) I have a new update to my classes that I'll send in after 7.2 is released. If you want, I can send in my new changes this week instead, though. My changes include 1) Renamding psqlProps.properties to pgDriver.properties 2) Wrapping each statement so that the driver can catch their errors so 3) Connections are removed in case of error 4) Alittle better pooling 5) Moved exception names into the errors.properties file So don't hold on to those classes I sent. Wait for my new ones. Thanks.

Bruce- Sure. I have to do it this weekend. Note that this contains changes to the DefaultProperties.java patch that you have planned to go into 7.3, so you might want to hold off on doing that one until I get you the new code.

Currently, no one is using DefaultProperties as of yet... I'll be the first. The pooled connection uses it mostly. The only thing in DefaultProperties that I changed was the name of the property file to be used... I stopped using psqlProps.properties and changed it to pgsqlDriver.properties instead. But I figure its easier to check in the 6 files I've got in one push.

It won't be 'released' until 7.3. Its a new feature, not a bug-fix. But it will be in CVS soon. (I didn't get a chance to finish it yesterday, so I'm going to try tonight.)
