c3p0 connection testing fetches metadata by default

Reported by Igmar Palsenberg | September 26th, 2013 @ 07:23 AM | in 1.3 (closed)

The c3p0 connection pooling fetches metadata by default. This means it does a getTables(). That's not a nice thing to do on a busy
database, since it will lock things up. It's also slow.

We can fix this a number of ways :

1) Let the user specify a query in the application.conf
2) Let c3p0 create a table itself
3) Use a standard query dependant in the driver class.

I prefer a combination of 1 and 3. We use a default query per driver class, and let the user override it if they want it.
This way, we can use the most optimal query per database.

I'd be happy to provide a pull request for this one.

<h2>Play framework</h2>

Play makes it easier to build Web applications with Java. It is a clean alternative to bloated Enterprise Java stacks. It focuses on developer productivity and targets RESTful architectures. Learn more on the <a href="http://www.playframework.org">http://www.playframework.org</a> website.<br><br>

<h2>Source code is hosted on github</h2>Check out our repository at <a href="http://github.com/playframework/play">http://github.com/playframework/play</a><br><br>

<h2>Contributing, creating a patch</h2> Please read the <a href="http://play.lighthouseapp.com/projects/57987/contributor-guide">contributor guide</a><br><br>

<h2>Reporting Security Vulnerabilities</h2> Since all bug reports are public, please report any security vulnerability directly to <em>guillaume dot bort at gmail dot com</em>.<br><br>

<h2>Creating a bug report</h2> Bug reports are incredibly helpful, so take time to report bugs and request features in our ticket tracker. We’re always grateful for patches to Play’s code. Indeed, bug reports with attached patches will get fixed far quickly than those without any.<br><br>

Please include as much relevant information as possible including the exact framework version you're using and a code snippet that reproduces the problem.<br><br>

Don't have too much expectations. Unless the bug is really a serious "everything is broken" thing, you're creating a ticket to start a discussion. Having a patch (or a branch on Github we can pull from) is better, but then again we'll only pull high quality branches that make sense to be in the core of Play.
