Sorry, I don't have patch, but regrtest.py -R not working now.

Sorry, I was stupid. I ran test in wrong directory.
release25-maint runs fine, and other two has same
error.

test_grammar skipped -- cannot import name _Abstract

I'm going to work on the issue later

It looks like you are running regrtest from the trunk with the py3k
interpretor.

Works for me.

Yes, I did mistake first, but py3k fails even in correct directory.

E:\python-dev\py3k\Lib\test>py3k --version
Python 3.0a3+

E:\python-dev\py3k\Lib\test>py3k regrtest.py -R :: test_os.py
test_os
test_os skipped -- cannot import name _Abstract
1 test skipped:
    test_os
1 skip unexpected on win32:
    test_os
[43267 refs]

abc._Abstract seems to be gone at r61098, but regrtest.py still
references to it.

attached simple patch seems to fix the problem but should be reviewed by
Christian.

It seems r61204 has fixed the bug. Can you test it on your machine
please? My old laptop is too slow.

> Can you test it on your machine please?

Running on a 4-core Opteron (2.6GHz).

Should complete in an hour or so ...

test_collections fails (with -R :: only).  Does not look like something
related to the recent changes, rather test is not happy about being
repeated.

Do buildbots run -R regressions?

I can see test_collections.py failure even on r61203
(just before Christian's commit) - r61098 (removed abc._Abstract)

I'll run py regrtest.py -R :: on r61203 - r61098 and compare its
result to Alexander's result, but my machine is damn slow, probably
it'll take long time.

Sorry, I abandoned this at test_compiler. Please forget this sentense...

Anyway, Christian's fix greatly works for me. Thanks!

>E:\python-dev\trunk\Lib\test>py regrtest.py -R :: test_collections.py

For this error, I could write a minimam code to reproduce it.
Please expand the attached zip file into lib/test and run a.py.
You'll see similar error.

I wrote simple patch to workaround this problem.
(avoid to reuse DocTestSuite)

# To my eyes, doctest.DocTestSuite(module=collections)
# and test_support.run_doctest(collections, verbose)
# are doing same test???

I did more investigation.
Failure on second DocTestSuite run happens because
lib/doctest.py (2107) test.globs.clear()
is executed after first test runs.

I don't know if this is bug or not. Document in
doctest.py says test.globs will be untouched on
failure but become empty on success, but this
behavior prevents reusage of DocTestSuite.
