The PR was merged, but we still need a checkout at this moment.

The real fix is in the AccessControl package, which we checkout on a specific branch here.

Make Redirect unavailable as url [2.13]

Skip IPv6 tests on Travis, as it is not supported.

Using the previously described variant using the index led to a broken installation because `pip` installs `Products.ZCatalog` 4.x. It expects to find `products.zcatalog` in the index. (Even downgrading to pip 1.5 does not help.)

This closes #194.

Explicitly require Manager role for `AltDatabaseManager`.

'bin/buildout -n' did not help.

That fixed the build for me locally.
Error on Travis:

If you use experimental.publishtraverse and try to call manage_pack,
it warns that the object (the manage_pack function) has no roles.
In strict mode it will fail.
This is an indication that the function *might* be available for anonymous users.
That is not the case here, but being strict seems good.

* Test that `str.format` checks the security for attributes that are accessed.

This needs https://github.com/zopefoundation/AccessControl/pull/23
This was merged, but not released yet, so we add AccessControl to auto-checkout for now.

* AccessControl has a release, no need for auto-checkout anymore.

In functional doc tests you can apparently have a test case that has
no runTest method.  Until now the Testing package added a dummy
runTest method in that case, and set it to None.

But when this dummy runTest method gets called, you get an error:

  Error in test runTest (Testing.ZopeTestCase.ZopeTestCase.FunctionalTestCase)
  Traceback (most recent call last):
    File ".../lib/python2.7/unittest/case.py", line 329, in run
      testMethod()
  TypeError: 'NoneType' object is not callable

Simply importing Testing.ZopeTestCase.FunctionalTestCase in a new test
file may be enough to trigger this.

So this has something to do with the order in which tests are found.

I fixed it by making the dummy runTest method callable.
