Juju is now on Github

[Ian Booth]

Hi folks

The migration of Juju source from Launchpad to Github is now complete for phase
one. The final location is at https://github.com/juju/juju

I say phase one because there are sill some follow up tasks to complete. You
will notice that the landing process (essentially the time taken to run the
tests) is longer. This is because we currently need to spin up an ephemeral EC2
instance rather than using a nailed up instance on Canonistack. We also need to
reduce the parallelism of the tests to get them reliably passing in that
environment. Addressing these issues is high on the priority list.

Note: only trunk is moved across to Github. Any work on 1.18.x will still need
to be done via Launchpad.

One thing you may want to do is redirect Juju project related notifications to a
work email address. Folks may have previously signed up to Github accounts with
personal email addresses. You can go into your profile and add a new email
address and redirect notifications for the Juju project to prevent spam to your
personal address.

As a reminder, the new landing workflow is documented in the Contributing
document https://github.com/juju/juju/blob/master/CONTRIBUTING

Don't forget, if you have in progress bzr branches, these can be migrated across
using the steps Martin previously sent out.

<snip>
$ cd $GOPATH/src
$ bzr branches launchpad.net/juju-core
* trunk
  wip_feature
$ bzr switch -d launchpad.net/juju-core wip_feature
$ (cd github.com/juju/juju&&git branch)
* master
$ (cd github.com/juju/juju&&git checkout -b wip_feature)
$ (cd launchpad.net/juju-core&&bzr diff -rancestor:co:trunk)|(cd
github.com/juju/juju&&patch  -p0 --merge)

Then resolve any conflicts, stage and commit.
<snip>

One improvement over the old system is that we now have visibility to how our
landings are progressing. There's a link to the Jenkins landing job in the pull
request email and from there you can see the console output of the test run.

Finally, there are bound to be some rough edges and process improvements we can
make as we all adjust to using this new environment. Please do speak up if there
are issues that need to be addressed.
