I've created a couple of sandbox trees on hg.openjdk.java.net. sandbox/simple is a simple push/pull tree that works in the obvious way.
sandbox/box is a gated tree; you pull from sandbox/box, and then push (via ssh) to sandbox/box-gate. If your new changesets pass the gate checks then they'll automagically be pushed to the sandbox/box tree. If they don't pass then your push transaction will be aborted. (At the moment there are no gate checks; that will change soon.) Notifications for these trees go to [EMAIL PROTECTED] Feel free to subscribe. If you'd like to play around with these -- even if you don't work at Sun -- send an ssh public key to [EMAIL PROTECTED] Have fun, and don't push anything huge or important or confidential to these trees. They will be reinitialized at random times. - Mark
