There used to be a problem when creating an object named 'index_html'
in Plone using WebDAV.

The problem occurred because Plone Folder's 'index_html' was a
ComputedAttribute used to acquire index_html from skins when there was
no index_html Document on the portal root.

However, this ComputedAttribute didn't handle WebDAV 'PUT' request
correctly. This test ensures that the fix doesn't regress.

  >>> from Products.CMFPlone.tests.PloneTestCase import default_user
  >>> from Products.CMFPlone.tests.PloneTestCase import default_password

Get path of our home folder:

  >>> folder_path = '/'.join(self.folder.getPhysicalPath())

Make sure index_html doesn't exist yet:

  >>> 'index_html' in self.folder.objectIds()
  False

PUT index_html into a Plone Folder. Should work just fine.

  >>> body = 'I am the walrus'
  >>> length = len(body)
  >>> print http(r"""
  ... PUT %s/index_html HTTP/1.1
  ... Content-Length: %d
  ... Authorization: Basic %s:%s
  ... <BLANKLINE>
  ... %s
  ... """ % (folder_path, length,
  ...        default_user, default_password, body),
  ...        handle_errors=False)
  HTTP/1.1 201 Created...

  >>> 'index_html' in self.folder.objectIds()
  True

  >>> print self.folder._getOb('index_html').meta_type
  ATDocument

Now, let's try the same at the Portal level:

  >>> portal_path = '/'.join(self.portal.getPhysicalPath())

Make sure index_html doesn't exist yet:

  >>> 'index_html' in self.portal.objectIds()
  False

But when we access it directly we should get a FSPageTemplate:

  >>> print self.portal.index_html.meta_type
  Filesystem Page Template

Give Manager role to the test user:

  >>> self.setRoles(['Manager'])

PUT index_html into Plone root. Should work just fine.

  >>> body = 'I am the walrus'
  >>> length = len(body)
  >>> print http(r"""
  ... PUT %s/index_html HTTP/1.1
  ... Content-Length: %d
  ... Authorization: Basic %s:%s
  ... <BLANKLINE>
  ... %s
  ... """ % (portal_path, length,
  ...        default_user, default_password, body),
  ...        handle_errors=False)
  HTTP/1.1 201 Created...

  >>> 'index_html' in self.portal.objectIds()
  True

  >>> print self.portal._getOb('index_html').meta_type
  ATDocument
