= Archive dependencies =

`ArchiveDependency` records represent build-dependencies between

archives, and are exposed through the API.

Most of the tests live in

lib/lp/soyuz/stories/webservice/xx-archive.txt.

Firstly we need to set some things up: we need a PPA with a dependency.

We'll use Celso's PPA, and give it a custom dependency on the primary

archive, and then create a private PPA for Celso with a similar custom

dependency.

    >>> import simplejson

    >>> from zope.component import getUtility

    >>> from lp.registry.interfaces.person import IPersonSet

    >>> from lp.registry.interfaces.pocket import PackagePublishingPocket

    >>> from lp.soyuz.interfaces.component import IComponentSet

    >>> login('foo.bar@canonical.com')

    >>> cprov_db = getUtility(IPersonSet).getByName('cprov')

    >>> cprov_ppa_db = cprov_db.archive

    >>> dep = cprov_ppa_db.addArchiveDependency(

    ...     cprov_ppa_db.distribution.main_archive,

    ...     PackagePublishingPocket.RELEASE,

    ...     component=getUtility(IComponentSet)['universe'])

    >>> cprov_private_ppa_db = factory.makeArchive(

    ...     private=True, owner=cprov_db, name="p3a",

    ...     distribution=cprov_ppa_db.distribution,

    ...     description="packages to help my friends.")

    >>> dep = cprov_private_ppa_db.addArchiveDependency(

    ...     cprov_ppa_db.distribution.main_archive,

    ...     PackagePublishingPocket.RELEASE,

    ...     component=getUtility(IComponentSet)['universe'])

    >>> logout()

Any user can retrieve a public PPA's dependencies.

    >>> print user_webservice.get(

    ...     '/~cprov/+archive/ppa/dependencies')

    HTTP/1.1 200 Ok

    ...

    >>> print user_webservice.get(

    ...     '/~cprov/+archive/ppa/+dependency/1')

    HTTP/1.1 200 Ok

    ...

The dependencies of a private archive are private.  Unprivileged users

can't get a list of the dependencies.

    >>> print user_webservice.get(

    ...     '/~cprov/+archive/p3a/dependencies')

    HTTP/1.1 401 Unauthorized

    ...

    (<Archive at ...>, 'dependencies', 'launchpad.View')

Nor can said user craft a URL to a dependency.

    >>> print user_webservice.get(

    ...     '/~cprov/+archive/p3a/+dependency/1')

    HTTP/1.1 401 Unauthorized

    ...

    (<Archive at ...>, 'getArchiveDependency', 'launchpad.View')

Celso can see them if we grant private permissions, of course.

    >>> from canonical.launchpad.testing.pages import webservice_for_person

    >>> from canonical.launchpad.webapp.interfaces import OAuthPermission

    >>> cprov_webservice = webservice_for_person(

    ...     cprov_db, permission=OAuthPermission.WRITE_PRIVATE)

    >>> print cprov_webservice.get(

    ...     '/~cprov/+archive/p3a/dependencies')

    HTTP/1.1 200 Ok

    ...

    >>> print cprov_webservice.get(

    ...     '/~cprov/+archive/p3a/+dependency/1')

    HTTP/1.1 200 Ok

    ...

But even he can't write to a dependency.

    >>> mark_ppa = cprov_webservice.get(

    ...     '/~mark/+archive/ppa').jsonBody()

    >>> print cprov_webservice.patch(

    ...     '/~cprov/+archive/ppa/+dependency/1', 'application/json',

    ...     simplejson.dumps({'archive_link': mark_ppa['self_link']}))

    HTTP/1.1 400 Bad Request

    ...
