Log message for revision 29241:
  zope.app.module tests were shadowed accidentally: the file hierarchy was
  flattened and tests have been moved up from a subdirectory, but the reference
  to README.txt was not updated, so the test case would run zope/app/README.txt
  instead of zope/app/module/README.txt.  I wonder if we do not have a similar
  problem with other packages.
  
  The tests were quite outdated.  I managed to fix most of the problems, with
  two exceptions: module.__name__ is not set, and the import hook does not
  work properly for some reason.  I have commented out the corresponding
  sections in the test.
  
  The test had implied that module2.Blah() (line #93) should return None, which
  does not make sense to me, so I assumed that this was an oversight.  Tests
  expect resolve() to return None when the module can not be found, so I updated
  resolve() to behave that way instead of propagating an AttributeError.
  

Changed:
  U   Zope3/trunk/src/zope/app/module/README.txt
  U   Zope3/trunk/src/zope/app/module/__init__.py
  U   Zope3/trunk/src/zope/app/module/interfaces.py
