Get rid of the ignore_imports argument to DocTestFinder.find(). This got slammed in when find() was fixed to stop grabbing doctests from modules imported by the module being tested. Such tests cannot be expected to succeed, since they'll be run with the current module's globals. Dozens of Zope3 doctests were failing because of that. It wasn't clear why ignore_imports got added then. Maybe it's because some existing tests failed when the change was made. Whatever, it's a Bad Idea so it's gone now. The only use of it was exceedingly obscure, in test_doctest's "Duplicate Removal" test. It was "needed" there because, as an artifact of running a doctest inside a doctest, the func_globals of functions compiled in the second-level doctest don't match the module globals, and so the test-finder believed these functions were from a foreign module and skipped them. But that took a long time to figure out, and I actually understand some of this stuff <0.9 wink>. That problem was resolved by moving the source code for the second-level doctest into an actual module (test/doctest_aliases.py). The only remaining difficulty was that the test for the deprecated Tester.rundict() then failed, because the test finder doesn't take module=None at face value, trying to guess which module the user really intended then. Its guess wasn't appropriate for what Tester.rundict needs when module=None is given to it, which is "no, there is no module here, and I mean it". So now passing module=False means exactly that. This is hokey, but ignore_imports=False was really a hack to worm around that there was no way to tell the test-finder that module=None sometimes means what it says. There was no use case for the combination of passing a real module with ignore_imports=False. 2004-08-08 03:11:48 -03:00			`# Used by test_doctest.py.`

Fix a bunch of doctests with the -d option of refactor.py. We still have 27 failing tests (down from 39). 2007-02-09 16:13:25 -04:00			`>>> print(TwoNames().f())`
