Please test out the new GUI charm's server

[Gary Poster]

Hi all.  The Juju GUI team is preparing a new feature [1] that requires
some significant changes to our charm [2].  We'd like your help for testing.

If you are deploying a new instance of the GUI, please include
"builtin-server=true" in your config.  For instance,

$ juju set juju-gui builtin-server=true

Once the charm has churned a bit, you'll have the change: the service
will be running a new server.  You can verify this by going to
/gui-server-info on the GUI: this exists in the new server and does not
in the old one.

Let us know--reply here or file a bug [3]--if you encounter any new
issues that seem to be related to the new server.

If you have a long-running GUI server, even better!  Please first
upgrade your charm...

$ juju upgrade-charm

...and then set the configuration given above.

Thanks!

Gary


[1] The new feature is "bundles".  Bundles are pre-configured
collections of services that can be deployed together.

[2] We had to write our own server in order to provide a way for the GUI
to interact with the Juju deployer
(https://code.launchpad.net/~juju-deployers/juju-deployer/darwin), which
provides the engine for bundles.
