Launchpad usage¶

All code used in mice is hosted on launchpad in the mice project group

Information for developers¶

If you have an existing launchpad project, you can make it a part of the MICE project group by doing

Project home page (e.g. https://launchpad.net/maus) > Change Details > "Part of" field > Enter "mice"

You can see all branches associated with all projects associated with mice by following

https://code.launchpad.net/mice

with options to sort by project/etc. You can create a new project in MICE by doing

https://launchpad.net/mice > Register a project in MICE Software

You should also ask to be added to mice-maintainers group.

Setting up bzr and launchpad¶

• You should install a recent version of bzr.
• You can get your bzr version by doing bzr --version
• You can get bzr from http://bazaar.canonical.com/en/ or usually apt-get or equivalent has a bzr version
• You need to set up a launchpad login and ssh keys at the launchpad website (https://launchpad.net/).
• Once you have a login, do

  bzr whoami "John Smith <john.smith@rl.ac.uk>"

• At RAL, you will should make sure your proxy is set by doing

  export https_proxy=http://wwwcache.rl.ac.uk:8080   ### Only if you are at RAL

• To use launchpad you will need to set your ssh rsa key. You can generate a ssh rsa public - private key pair from the linux command line using:

  ssh-keygen

  Make sure you set a good password when given the option (too weak and the process will fail). This then generates two files, id_rsa (your private key) and id_rsa.pub (your public key). Both files should be put in the (hidden) directory:

  ~/.ssh/

  You will need to set the permissions on the files too, using the following:
  

  chmod 600 id_rsa
  chmod 640 id_rsa.pub
  

  For the interested reader, there is a nice chmod tutorial available at http://catcode.com/teachmod/ .
  Upload the text of your public key to your launchpad account, and you are good to go.

• Once you have set up your key, you will be able to connect bazaar to your launchpad ID with:

  bzr launchpad-login jsmith

Initialise a project as bzr¶

If you have an existing code project, make it a bzr project by doing

cd <my-project>
bzr init
bzr push lp:~<user-name>/<project-name>/branch-name
