Rebuild the DocTestSuite on each iteration.

When cls is an ABCMeta, every call to isinstance(x, cls)
records type(x) in the cls._abc_cache of cls_abc_negative_cache.
So we clear these caches at the end of the test.

inspect.isabstract() is not the correct test for all ABCs, because there is no @abstractmethod in io.py (why?)
isinstance(cls, ABCMeta) would be more exact, but it fails with an infinite recursion.
So I used a hack to determine whether a class is an ABCMeta.

The true correction would be to turn cls._abc_cache &co into a WeakSet, as py3k does.
But classic classes are not weak referenceable...

Of course, this change should not be merged into the py3k branch.

I have the email trail to prove that George Neville-Neil approved this.

it registers the same codec on each iteration.
Do it only once at load time.

with python 2.6, enumerating bytes yields 1-char strings, not numbers.

Don't merge this into the py3k branch.

of effort to do so.

it is easy to capture stderr if desired.

fine, but the last change may be required for the test to pass on Windows.
Should we always close the mmap too?

Thanks to Wummel for the patch

the test itself doesn't do anything on windows, focus on setUp and tearDown.

http://www.python.org/dev/buildbot/trunk/x86%20W2k8%20trunk/builds/255/step-test/0

Temporarily increase verbosity of this test.

compile() when compiling an AST node.

except in verbose mode.
Support code is much simpler.

not when used as a library.

This may please the buildbots, which fail when test_lib2to3 is run before test_logging.

otherwise running test_logging twice produce the errors we see on all buildbots

complained about commit, rollback and close not being documented.

Undo the only change that might have unexpected effects.

To be followed.

in pyconfig.h, NTDDI_WIN2KSP4 is not *yet* defined, but will be at some point on some modules.

Let this line even for older SDKs, they don't use it anyway.

I applied the same changes manually to VS7.1 and VC6 files; completely untested.

(Christian, don't try too hard merging this change into py3k.
It will be easier to do the same work again on the branch)
