Private by default bugs
=======================

A product with private bugs by default must always have a bug supervisor
(this is enforced by a DB constraint).

    >>> from lp.testing.layers import LaunchpadZopelessLayer
    >>> from lp.bugs.interfaces.bug import CreateBugParams
    >>> from lp.registry.interfaces.person import IPersonSet
    >>> from lp.registry.interfaces.product import IProductSet
    >>> LaunchpadZopelessLayer.switchDbUser('launchpad')
    >>> no_priv = getUtility(IPersonSet).getByName('no-priv')
    >>> name16 = getUtility(IPersonSet).get(16)
    >>> landscape = getUtility(IProductSet).getByName('landscape')
    >>> landscape.private_bugs
    True

    >>> login('foo.bar@canonical.com')
    >>> landscape.security_contact = name16
    >>> login('no-priv@canonical.com')

    >>> bug_params = CreateBugParams(
    ...     owner=no_priv, title='Some bug', comment='I like monkeys.')

    >>> bug = landscape.createBug(bug_params)
    >>> [landscape_task] = bug.bugtasks
    >>> landscape_task.bug.private
    True

    >>> landscape_task.bug.security_related
    False

    >>> landscape.bug_supervisor.name
    u'landscape-developers'

    >>> landscape.owner.name
    u'name12'

    >>> sorted(sub.name for sub in landscape_task.bug.getDirectSubscribers())
    [u'landscape-developers', u'no-priv']

The bug supervisor is always subscribed, except in the case of a security
related bug.

    >>> security_bug_params = CreateBugParams(
    ...     owner=no_priv, title='Security bug',
    ...     comment='A monkey took my GPG keys.',
    ...     security_related=True)
    >>> security_bug = landscape.createBug(security_bug_params)
    >>> [security_bug_task] = security_bug.bugtasks
    >>> security_bug_task.bug.private
    True

For a security related bug, the security contact or the product owner
(if no security contact) is subscribed.

    >>> security_bug_task.bug.security_related
    True

    >>> landscape.security_contact.name
    u'name16'

    >>> sorted(
    ...     sub.name for sub in security_bug_task.bug.getDirectSubscribers())
    [u'name16', u'no-priv']
