Update Launchpad Dependency

Scenario: You need to update a dependency hosted on Launchpad. This example uses gomaasapi:

Updating the LP package

Branch trunk

• cd $GOPATH/src/launchpad.net/gomaasapi
• bzr branch . /path/to/your/branches/nameofbranch
• cd /path/to/your/branches/nameofbranch

Edit

If you made your changes to trunk before branching, you can pull those changes across like so: bzr merge --uncommitted /trunk/branch/directory. Once you are ready to propose:

• bzr commit -m"commit message"
• bzr push lp:~<lp username>/gomaasapi/nameofbranch
• View your branch at https://code.launchpad.net/~<lp username>/gomaasapi/nameofbranch
• Click the button on this page to propose the branch for merging into trunk.
• Wait for review approval

Merge back into trunk

• cd ~/go/src/launchpad.net/gomaasapi
• bzr merge ~/branches/nameofbranch
• bzr push lp:gomaasapi
• Update branch status to "merged" on lp website

Updating Juju to use the new revision

Get revision ID and number to update dependencies.tsv

• Get the revision number: bzr revno
• Then get the revision id: http://bazaar.launchpad.net/~juju/gomaasapi/trunk/revision/<revision number>

Be sure to run godeps -u dependencies.tsv and dependenciesTest suite after you've updated the file.
