regardless of the native sizeof(long) used in the integer object.
This somewhat odd behavior of returning a signed is maintained in 2.x for
compatibility reasons of always returning an integer rather than a long object.
Fixes Issue1202 for Python 2.6
Added 0b and 0o literals to tokenizer.
Modified PyOS_strtoul to support 0b and 0o inputs.
Modified PyLong_FromString to support guessing 0b and 0o inputs.
Renamed test_hexoct.py to test_int_literal.py and added binary tests.
Added upper and lower case 0b, 0O, and 0X tests to test_int_literal.py
Added "Z" format_char to PyOS_ascii_formatd to support empty float presentation type.
Renamed buf_size in PyOS_ascii_formatd to more accurately reflect it's meaning.
Modified format.__float__ to use the new "Z" format as the default.
Added test cases.
Unlike Scheme where exactness is implemented as taints, the Python
implementation associated exactness with data types. This created
inheritance issues (making an exact subclass of floats would result
in the subclass having both an explicit Exact registration and an
inherited Inexact registration). This was a problem for the
decimal module which was designed to span both exact and inexact
arithmetic. There was also a question of use cases and no examples
were found where ABCs for exactness could be used to improve code.
One other issue was having separate tags for both the affirmative
and negative cases. This is at odds with the approach taken
elsewhere in the Python (i.e. we don't have an ABC both Hashable
and Unhashable).
across platforms: it should now raise OverflowError on all
platforms. (Previously it raised OverflowError only on
non IEEE 754 platforms.)
Also fix the (already existing) test for this behaviour
so that it actually raises TestFailed instead of just
referencing it.
SocketServers. The core of the patch was written by Pedro Werneck, but any bugs
are mine. I've also rearranged the code for timeouts in order to avoid
interfering with the shutdown poll.
before timing out. This doesn't change the duration of the test under
normal circumstances. This is targetted at fixing the spurious failures
on the FreeBSD buildbot primarily.
