RuntimeError produced when profiling the decimal module. This was
due to a dangerous iteration over 'locals()' in Context.__init__.

Issue #8567: Fix incorrect precedence of signals in Decimal module.
When a Decimal operation raises multiple signals and more than one of
those signals is trapped, the specification determines the order in
which the signals should be handled. In many cases this order wasn't
being followed, leading to the wrong Python exception being raised.
This commit fixes those cases, and adds extra tests. The tests are
only enabled when EXTENDEDERRORTESTS is True, since they involve
rerunning each Decimal testcase several times.

Issue #7048: logb should round its result when that result doesn't fit
into the available precision. (Tests for this change are included in
the most recent set of testcases from the Decimal Specification site;
those testcases will be updated shortly.)

Issue #4084: Fix max, min, max_mag and min_mag Decimal methods to
give correct results in the case where one argument is a quiet NaN
and the other is a finite number that requires rounding.

* crashes on memory allocation failure found with failmalloc
* memory leaks found with valgrind
* compiler warnings in opt mode which would lead to invalid memory reads
* problem using wrong name in decimal module reported by pychecker
Update the valgrind suppressions file with new leaks that are small/one-time
leaks we don't care about (ie, they are too hard to fix).

that the behaviour of Decimal doesn't change if/when re.UNICODE becomes
assumed in Python 3.0.
Also add a check that alternative Unicode digits (e.g. u'\N{FULLWIDTH
DIGIT ONE}') are *not* accepted in a numeric string.
at reducing the size of the diff between the 2.x decimal.py
and 3.x decimal.py and thereby making future merges easier:
- replace one instnace of an old-style raise statement
- define __div__ in terms of __truediv__ instead of the
other way around
- make wording match on an exception message
number: now it does not store the mantissa as a tuple
of numbers, but as a string.
This avoids a lot of conversions, and achieves a
speedup of 40%. The API remains intact.
Thanks Mark Dickinson.
coefficient numbers, floats in the sign, and other details that
generated directly the wrong number in the best case, or triggered
misfunctionality in the alorithms.
Test cases added for these issues. Thanks Mark Dickinson.
with Cawlishaw by mail, and he basically confirmed that to these is_*
operations, there's no need to return Decimal(0) and Decimal(1) if
the language supports the False and True booleans.
Also added a few tests for the these functions in extra.decTest, since
they are mostly untested (apart from the doctests).
