the string one line at a time. The resulting code is (in my opinion,
anyway), much easier to read. In the process, I found and fixed a
bug in the orginal parser's line numbering in error messages (it was
inconsistant between 0-based and 1-based). Also, check for missing
blank lines after the prompt on all prompt lines, not just PS1 lines
(test added).
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.
Ripped out the docs for the new DocTestFinder's namefilter argument,
and renamed it to _namefilter; this only existed to support isprivate.
Removed the new DocTestFinder's objfilter argument. No point adding
more cruft to a broken filtering design.
the tim-doctest-merge-24a2 tag on the the tim-doctest-branch branch.
We did development on the branch in case it wouldn't land in time for
2.4a2, but the branch looked good: Edward's tests passed there, ditto
Python's tests, and ditto the Zope3 tests. Together, those hit doctest
heavily.
imports e.g. test_support must do so using an absolute package name
such as "import test.test_support" or "from test import test_support".
This also updates the README in Lib/test, and gets rid of the
duplicate data dirctory in Lib/test/data (replaced by
Lib/email/test/data).
Now Tim and Jack can have at it. :)
horridly inefficient hack in regrtest's Compare class, but it's about as
clean as can be: regrtest has to set up the Compare instance before
importing a test module, and by the time the module *is* imported it's too
late to change that decision. The good news is that the more tests we
convert to unittest and doctest, the less the inefficiency here matters.
Even now there are few tests with large expected-output files (the new
cost here is a Python-level call per .write() when there's an expected-
output file).
