gf.recipe.bzr 1.0dev-20090103

Goals

• Allow fetching eggs directly from bzr repositories.

• The specified repositories are branched locally on the first buildout run. It is possible to use these local branches for development and make local changes. The local changes can be committed locally, and can be pushed back to the remote repository or to any other location.

• When buildout is run again, the branches are updated (pulled) automatically from the remote location. If pulling would cause conflicts, buildout stops with an error. The parent branch (pull) location remembered by bazaar will be used for pulling, so it is possible to change this any time from bzr.

• Local changes can be pushed back to the remote branches. This is also enforced: When buildout wants to uninstall the local branches, they are checked. If they contain uncommitted or unpushed local changes, buildout stops with an error. This forces developers to save local changes to upstream and avoids loosing local work.

• When buildout checks if the branches contain local changes, the parent (pull) location and the push location, remembered by bazaar, are used (in this order). This makes it possible to switch existing branches during development, without changing the buildout configuration.

• Parameters are similar to those used with “infrae.subversion” and also compatible with the “bazaarrecipe” package.

• With bzr-svn, the remote branch can also be an svn branch. So it actually can be used to branch off native svn repository branches as well (although, performance of updates and sanity checks may depend on bzr-svn’s performance, thus infrae.subversion may provide faster operation for svn.)

Usage

Usage example:

[bzr]
recipe = gf.recipe.bzr
urls =
    http://bazaar.launchpad.net/~kissbooth/kss.plugin.sdnd/trunk kss.plugin.sdnd
    http://bazaar.launchpad.net/~kissbooth/kss.plugin.livesearch/trunk kss.plugin.livesearch
in_parts = False
http_authentication = username:password

This will bzr get the branches to bzr/kss.plugin.sdnd and bzr/kss.plugin.livesearch. Branches are pulled if buildout is called. Uninstall is protected, if there are local modifications, or modifications that are missing in the upstream, an error will be raised. In case you create a local bzr directory, make sure it has a push location, otherwise uninstall will fail.

No directories are really removed on uninstall, this has the consequence that if the setup is changed, the local repositories will not follow it.

[kukit.js]
recipe = gf.recipe.bzr
urls=
    https://codespeak.net/svn/kukit/kukit.js/trunk              trunk
    https://codespeak.net/svn/kukit/kukit.js/branch/1.2         1.2
    https://codespeak.net/svn/kukit/kukit.js/branch/1.4         1.4
develop = False

[kss.demo]
recipe = gf.recipe.bzr
urls=
    https://codespeak.net/svn/kukit/kss.demo/trunk              trunk
    https://codespeak.net/svn/kukit/kss.demo/branch/1.2         1.2
    https://codespeak.net/svn/kukit/kss.demo/branch/1.4         1.4
develop = False

Other configuration needed

In addition you also need to include the eggs you configured with the recipe, in the buildout section:

[buildout]
...
eggs =
    ...
    kss.plugin.sdnd
    kss.plugin.livesearch
