Features added
- Acquisition has been made aware of __parent__ pointers. This allows
direct access to many Zope 3 classes without the need to mixin
Acquisition base classes for the security to work.
- Zope2 startup: Zope will now send DatabaseOpened and
ProcessStarting events.

Testing legacy browser views
============================
This test tests publishing aspects of browser pages. Let's register
some:
>>> import Products.Five.browser.tests
>>> from Products.Five import zcml
>>> zcml.load_config("configure.zcml", Products.Five)
>>> zcml.load_config('aqlegacy.zcml', package=Products.Five.browser.tests)
>>> from Products.Five.testbrowser import Browser
>>> browser = Browser()
>>> browser.handleErrors = False
Acquisition API legacy on BrowserView
-------------------------------------
Let's make sure that accessing those old aq_* properties on browser
views still works (the printed output is the aq_chain of the view):
>>> browser.open('http://localhost/test_folder_1_/attributes')
>>> print browser.contents
[<Products.Five.metaclass.LegacyAttributes object at ...>,
<Folder at /test_folder_1_>,
<Application at >,
<ZPublisher.BaseRequest.RequestContainer object at ...>]
The same goes for browser views that just mix in Acquisition.Explicit:
>>> browser.open('http://localhost/test_folder_1_/explicitattributes')
>>> print browser.contents
[<Products.Five.metaclass.ExplicitLegacyAttributes object at ...>,
<Folder at /test_folder_1_>,
<Application at >,
<ZPublisher.BaseRequest.RequestContainer object at ...>]
Let's do some more manual tests with the view object. But first we
must get it:
>>> from zope.component import getMultiAdapter
>>> from zope.publisher.browser import TestRequest
>>> request = TestRequest()
>>> view = getMultiAdapter((self.folder, request), name='attributes')
Let's check for the various aq_* attributes:
>>> view.aq_parent == self.folder
True
>>> view.aq_inner == view
True
>>> view.aq_base == view
True
>>> view.aq_self == view
True
Let's try to acquire something from the root folder:
>>> button = view.aq_acquire('ZopeAttributionButton')
>>> print button()
<a href="http://www.zope.org/Credits" target="_top"><img src="http://nohost/p_/ZopeButton" width="115" height="50" border="0" alt="Powered by Zope" /></a>
Let's check that we're in the right context:
>>> view.aq_inContextOf(self.folder)
1
>>> view.aq_inContextOf(self.app)
1
>>> view.aq_inContextOf(object())
0
Views also still support the __of__ protocol, at least pro forma:
>>> view == view.__of__(self.app)
True
Acquisition API legacy on a browser view's template
---------------------------------------------------
A view's template will also support the various aq_* attributes:
>>> view = getMultiAdapter((self.folder, request), name='template')
>>> template = view.template
>>> template.aq_parent == view
True
>>> template.aq_inner == template
True
>>> template.aq_base == template
True
>>> template.aq_self == template
True
>>> button = template.aq_acquire('ZopeAttributionButton')
>>> print button()
<a href="http://www.zope.org/Credits" target="_top"><img src="http://nohost/p_/ZopeButton" width="115" height="50" border="0" alt="Powered by Zope" /></a>
Mixing in Acquisition.{Ex|Im}plicit
-----------------------------------
Let's make sure that mixing in Acquisition.Explicit or Implicit won't
mess up your views (even though you should never have done it in the
first place...):
>>> browser.open('http://localhost/test_folder_1_/explicit')
>>> print browser.contents
Explicit
>>> browser.open('http://localhost/test_folder_1_/explicit_zcmltemplate')
>>> print browser.contents
<p>The falcon has taken flight</p>
>>> browser.open('http://localhost/test_folder_1_/explicit_template')
>>> print browser.contents
<p>The falcon has taken flight</p>
>>> browser.open('http://localhost/test_folder_1_/implicit')
>>> print browser.contents
Implicit
>>> browser.open('http://localhost/test_folder_1_/implicit_template')
>>> print browser.contents
<p>The falcon has taken flight</p>
>>> browser.open('http://localhost/test_folder_1_/implicit_zcmltemplate')
>>> print browser.contents
<p>The falcon has taken flight</p>
Testing legacy content providers and viewlets
=============================================
>>> browser.open('http://localhost/test_folder_1_/aqlegacyprovider')
>>> print browser.contents
<p>Content provider inheriting from Explicit</p>
>>> browser.open('http://localhost/test_folder_1_/aqlegacymanager')
>>> print browser.contents
<p>BrowserView viewlet
Viewlet inheriting from Explicit</p>
Testing namespace traversal
===========================
Namespace traversal can turn up objects during traversal without
attribute access. That means they might not be wrapped by default.
Here we make sure that they are wrapped and that things like the
request can be acquired.
First let's try ``restrictedTraverse()``:
>>> foo = self.folder.restrictedTraverse('++aqlegacy++foo')
>>> import Acquisition
>>> Acquisition.aq_acquire(foo, 'REQUEST')
<HTTPRequest, URL=http://nohost>
Now let's try URL traversal:
>>> browser.open('http://localhost/test_folder_1_/++aqlegacy++foo/index.html')
>>> print browser.contents
<p>The falcon has taken flight</p>
Testing keyword arguments
=========================
ViewPageTemplateFile's take arbitrary keyword arguments:
>>> view = getMultiAdapter((self.folder, request), name='template')
>>> template = view.template
>>> print template(foo=1, bar=2)
<p>The falcon has taken flight</p>
Passing in an argument called instance was supported by the old Five version
of ViewPageTemplateFile, so we still need to support it.
In the zope.app.pagetemplate version, the first required argument is called
instance, though.
>>> print template(instance='allowed')
<p>The falcon has taken flight</p>
No arguments required
=====================
ViewPageTemplateFile's require no arguments, but you can only use them as
class variables:
>>> view = getMultiAdapter((self.folder, request), name='template_two')
>>> print view()
Traceback (most recent call last):
...

reason is that __roles__ actually is an object that expects being
called through the __of__ protocol upon which it renders the roles
tuple. aq_acquire will trigger this for us. This isn't a problem,
really, because AccessControl ends up using aq_acquire anyway, so it
