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The tests were quite outdated.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:
