WebDAV and Versioning
=====================

This doctest makes sure that WebDAV changes to Archetypes-based
objects trigger versioning correctly:

  >>> from pprint import pprint
  >>> from StringIO import StringIO
  >>> from Products.Archetypes.tests.utils import makeContent
  >>> from Products.Archetypes.interfaces import IBaseObject
  >>> from plone.app.testing import TEST_USER_ID
  >>> from plone.app.testing import TEST_USER_NAME
  >>> from plone.app.testing import TEST_USER_PASSWORD

Doing a `PUT` request that creates a brand new object, and so should
create and save an initial version as happens when creating a brand
new object via the Plone UI:

  >>> from plone.app.testing import setRoles
  >>> portal = layer['portal']
  >>> setRoles(portal, TEST_USER_ID, ['Manager'])
  >>> folder = portal.portal_membership.getHomeFolder(TEST_USER_ID)

  >>> 'some-document' in folder.objectIds()
  False

  >>> from Testing.ZopeTestCase.zopedoctest.functional import http
  >>> from Testing.ZopeTestCase.sandbox import AppZapper
  >>> AppZapper().set(layer['app'])
  >>> print http(r"""
  ... PUT /%s/some-document HTTP/1.1
  ... Authorization: Basic %s:%s
  ... Content-Type: text/plain; charset="utf-8"
  ...
  ... Some Content
  ... """ % ('/'.join(folder.getPhysicalPath()), TEST_USER_NAME, TEST_USER_PASSWORD))
  HTTP/1.1 201 Created
  ...

  >>> 'some-document' in folder.objectIds()
  True

  >>> print str(folder['some-document']['text'])
  Some Content


There should be only one history entry and not two or more

  >>> portal_repo = portal.portal_repository
  >>> len(portal_repo.getHistory(folder['some-document']))
  1

Doing another `PUT` request to update the same object should cause
another version of the object to be saved:

  >>> print http(r"""
  ... PUT /%s/some-document HTTP/1.1
  ... Authorization: Basic %s:%s
  ... Content-Type: text/plain; charset="utf-8"
  ...
  ... Some Other Content
  ... """ % ('/'.join(folder.getPhysicalPath()), TEST_USER_NAME, TEST_USER_PASSWORD))
  HTTP/1.1 204 No Content
  ...

  >>> print str(folder['some-document']['text'])
  Some Other Content

  >>> len(portal_repo.getHistory(folder['some-document']))
  2

Creating a folder does not trigger a revision because the policy is
not configured for folders:

  >>> print http(r"""
  ... MKCOL /%s/some-folder HTTP/1.1
  ... Authorization: Basic %s:%s
  ... """ % ('/'.join(folder.getPhysicalPath()), TEST_USER_NAME, TEST_USER_PASSWORD))
  HTTP/1.1 201 Created
  ...

  >>> len(portal_repo.getHistory(folder['some-folder']))
  0
