Tests to address migration bugs
================================

Special cases to look for in fixing migration bugs.

Issue #8784: content owned by no-longer existing member ends up with
a bogus local roles entry, resulting in anonymous users gaining ownership
of the content.

    >>> from Products.CMFCore.permissions import ModifyPortalContent
    >>> from Products.CMFCore.permissions import ManageUsers
    >>> from Products.CMFPlone.utils import _createObjectByType  
    >>> app = layer['app']
    >>> portal = layer['portal']
    >>> portal.manage_permission(
    ...     ModifyPortalContent, ['Manager', 'Owner'], acquire=0)

    Create a 'tempuser' to generate some content, then delete the user
    prior to migration

    >>> member_id = 'tempuser'
    >>> portal.portal_membership.addMember(member_id, 'secret',
    ...     ('Member', 'Manager'), [])
    >>> user = portal.acl_users.getUserById(member_id)
    >>> from plone.app import testing
    >>> testing.login(portal, member_id)

    >>> bar_doc = _createObjectByType(
    ...     'Document', portal, id='bar', title='Bar')
    >>> bar_doc.portal_type, bar_doc.getId(), bar_doc.Title()
    ('Document', 'bar', 'Bar')

    Demonstrate healthy local_roles before the migration

    >>> inner_obj = getattr(bar_doc, 'aq_inner', bar_doc)
    >>> marker = object()
    >>> local_roles = getattr(inner_obj, '__ac_local_roles__', marker)
    >>> member_id in local_roles.keys()
    True
    >>> None in local_roles.keys()
    False

    Delete the member

    >>> from plone.testing import z2
    >>> z2.login(app['acl_users'], testing.SITE_OWNER_NAME)
    >>> portal.portal_membership.deleteMembers([member_id])
    ('tempuser',)

    Local roles still healthy

    >>> local_roles = getattr(inner_obj, '__ac_local_roles__', marker)
    >>> member_id in local_roles.keys()
    False
    >>> None in local_roles.keys()
    False

    >>> from transaction import commit
    >>> commit()

    >>> from Products.contentmigration.archetypes import ATItemMigrator
    >>> bar_migrator = ATItemMigrator(bar_doc)
    >>> bar_migrator.dst_portal_type = 'News Item'
    >>> bar_migrator.dst_meta_type = 'ATNewsItem'
    >>> bar_migrator.migrate()
    >>> bar_news = portal.bar
    >>> bar_news.portal_type, bar_news.getId(), bar_news.Title()
    ('News Item', 'bar', 'Bar')

    Confirm that after the migration, the local roles don't contain
    the bogus 'None' key

    >>> inner_obj = getattr(bar_news, 'aq_inner', bar_news)
    >>> local_roles = getattr(inner_obj, '__ac_local_roles__', marker)
    >>> local_roles is None
    True

Locked objects should be unlocked before being migrated

    >>> z2.login(app['acl_users'], testing.SITE_OWNER_NAME)
    >>> foo_doc = _createObjectByType(
    ...     'Document', portal, id='foo', title='Foo')
    >>> foo_doc.portal_type, foo_doc.getId(), foo_doc.Title()
    ('Document', 'foo', 'Foo')
    >>> commit()

    >>> foo_doc = portal.foo
    >>> from plone.locking.interfaces import ILockable
    >>> ILockable(foo_doc).lock()
    >>> foo_migrator = ATItemMigrator(foo_doc)
    >>> foo_migrator.dst_portal_type = 'News Item'
    >>> foo_migrator.dst_meta_type = 'ATNewsItem'
    >>> foo_migrator.migrate()
    >>> foo_news = portal.foo
    >>> foo_news.portal_type, foo_news.getId(), foo_news.Title()
    ('News Item', 'foo', 'Foo')

Objects locked with webdav should also be unlocked before being
migrated.  We cheat when pretending to be locked by webdav in this
test by patching the relevant webdav methods.

    >>> z2.login(app['acl_users'], testing.SITE_OWNER_NAME)
    >>> dav_doc = _createObjectByType(
    ...     'Document', portal, id='dav', title='Dav')
    >>> dav_doc.portal_type, dav_doc.getId(), dav_doc.Title()
    ('Document', 'dav', 'Dav')
    >>> commit()

    >>> dav_doc = portal.dav
    >>> _orig_wl_isLocked = dav_doc.wl_isLocked
    >>> def dummy_isLocked():
    ...     return True
    >>> def dummy_clearLocks():
    ...     dav_doc.wl_isLocked = _orig_wl_isLocked
    >>> dav_doc.wl_isLocked = dummy_isLocked
    >>> dav_doc.wl_clearLocks = dummy_clearLocks

    >>> dav_migrator = ATItemMigrator(dav_doc)
    >>> dav_migrator.dst_portal_type = 'News Item'
    >>> dav_migrator.dst_meta_type = 'ATNewsItem'
    >>> dav_migrator.migrate()
    >>> dav_news = portal.dav
    >>> dav_news.portal_type, dav_news.getId(), dav_news.Title()
    ('News Item', 'dav', 'Dav')
