Expose a webservice method to retrieve copy archives

[William Grant]

In my copy archive FTBFS reporting scripts I must currently construct a URL to the copy archive. IDistribution should provide a method to retrieve copy archives by name, and this should be exposed on the webservice.

The easiest thing to do seems to be to move lp.soyuz.browser.archive.traverse_distribution_to_archive to Distribution.getArchive and export that. Any objections?

Sounds fine to me.

Just in case it's needed, it is possible to load the copy archive manually and use it in the API:

{{{
copy_archive = launchpad.load('https://api.launchpad.net/beta/ubuntu/+archive/test-rebuild-20100407')
}}}

Fixed in stable r10927 <http://bazaar.launchpad.net/~launchpad-pqm/launchpad/stable/revision/10927>

QA:

>>> import launchpadlib
>>> from launchpadlib.launchpad import Launchpad
>>> lp = Launchpad.login_anonymously('qa', 'edge')
>>> lp.distributions['ubuntu'].getArchive(name='primary')
<archive at https://api.edge.launchpad.net/1.0/ubuntu/+archive/primary>
>>> lp.distributions['ubuntu'].getArchive(name='ppa')
>>> lp.distributions['ubuntu'].getArchive(name='test-rebuild-20100407')
<archive at https://api.edge.launchpad.net/1.0/ubuntu/+archive/test-rebuild-20100407>
>>> lp.distributions['ubuntu'].getArchive(name='test-rebuild-20100403')
