test.support.captured_output is not covered in the online documents:
http://docs.python.org/3.1/library/test.html
http://docs.python.org/dev/py3k/library/test.html
However, it does have a docstring in C:\Python31\Lib\test\support.py
Mark Dickinson dicki...@gmail.com added the comment:
Specifically, the behaviour comes from an early check for empty strings in the
PyUnicode_FromEncodedObject function:
/* Convert to Unicode */
if (len == 0) {
Py_INCREF(unicode_empty);
v = (PyObject *)unicode_empty;

Will ponder this a bit more but will likely close this specific request
(leaving open the possibility of a more general rewrite of pprint).

OK.
The attached patch removes the empty string check before decoding.
I'm not sure where tests should go, since I can only find them in Lib/test/ and
this is not a library change.

I wonder: with year bounds being checked in gettmarg() and mktime accepting
arbitrary values for the rest of the tm structure members (at least it appears
to on my Mac), is it possible trigger mktime argument out of range?
Mark Dickinson dicki...@gmail.com added the comment:
Thanks for the patch.
Rather than remove that optimization entirely, I'd consider pushing it into
PyUnicode_Decode.
All tests (whether for the standard library or for the core) go into Lib/test,
so that would be the right place.
Mark Dickinson dicki...@gmail.com added the comment:
I take that back: test_codecs_errors isn't the right function to add these
tests to. I actually don't see any current tests for invalid codecs. Part of
the problem would be coming up with an invalid codec name in the first place:
as I
Mark Dickinson dicki...@gmail.com added the comment:
And PyUnicode_Decode doesn't look up the encoding in the registry either:
that's somewhere in PyCodec_Decode.
I'm going to butt out now and leave this to those who know the code better. :)

Ori Avtalion o...@avtalion.name added the comment:
Ignoring the custom utf-8/latin-8 conversion functions, the actual checking if
a codec exists is done in Python/codecs.c's PyCodec_Decode.
Is that where I should move the aforementioned optimization to?
Is it safe to assume that the decoded

Victor,
As you explain in your own documentation, the proposed method is equivalent to
``(time.mktime(self.timetuple()), self.microsecond)``, so all it does is
replacing a less than a one-liner. Moreover, I am not sure

Thanks for fixing the argument positions;
unfortunately, it seems, there might be some other problem, that makes my code

Phillip J. Eby p...@telecommunity.com added the comment:
What sort of test did you have in mind? To test the desired outcome, it seems
we'd need to poison os.environ, reload wsgiref.handlers, remove the poison, and
then make sure it didn't get in. That seems a bit like overkill (as well as
