Idle code already uses x.delegate instead of x.getdelegate().
The printed report must have been for testing.

Brett already fixed this in 3.4 in 4f7c25ab2ed2.

Patch by Vajrasky Kok, with slight modification to the tests by me.

u can be NULL, use XDECREF

replacing warnings.formatwarnings and to reverse replacement of
warnings.showwarnings when import is complete and when main function exits.
Add test_warning.py. Vinay Sajip provided capture_warnings function.

If buildbots run before next push, test_logging will (temporarily) fail.

replacing redundant signature in input() docstring with one-line summary.
Original patch by Terrel Shumway.

We ran into this during the sprits at PyCon and this patch has been
sitting on my disk ever since.  This just adds some information to the
error message that we found useful during debugging.  There's no good
way to add a test, since the message only got generated via code
that we had modified for debugging purposes.

applicable.

There were no tests for the encoders module.  encode_base64 worked
because it is the default and so got tested implicitly elsewhere, and
we use encode_7or8bit internally, so that worked, too.  I previously
fixed encode_noop, so this fix means that everythign in the encoders
module now works, hopefully correctly.  Also added an explicit test
for encode_base64.
