Mark Dickinson a493ca3fae Issue #12080: Fix a performance issue in Decimal._power_exact that caused some corner-case Decimal.__pow__ calls to take an unreasonably long time. 2011-06-04 18:24:15 +01:00
Raymond Hettinger d92232976e Neaten-up the fix to issue 11830 2011-04-12 09:06:01 -07:00
Raymond Hettinger e4579c3380 Issue #11830: Remove unnecessary introspection code in the decimal module.
It was causing a failed import in the Turkish locale where the locale
sensitive str.upper() method caused a name mismatch.

Mark Dickinson 4f96f5ffc6 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.

Raymond Hettinger ed171abd93 Issue 8257: Decimal constructor to accept float. 2010-04-02 18:39:24 +00:00
Mark Dickinson f3eeca16cb Issue #7279: Make Decimal('nan') hashable. Decimal('snan') remains unhashable.
Also rewrite the Decimal __hash__ method so that it doesn't rely on
float('inf') being valid: float('inf') could raise an exception on
platforms not using IEEE 754 arithmetic.

Mark Dickinson e096e82e82 Issue #7279: Make comparisons involving a Decimal sNaN signal InvalidOperation. 2010-04-02 10:17:07 +00:00
Mark Dickinson 99d8096c17 Issue #2531: Make float-to-decimal comparisons return correct results.
Float to decimal comparison operations now return a result based on
the numeric values of the operands.  Decimal.__hash__ has also been
fixed so that Decimal and float values that compare equal have equal
hash value.

Mark Dickinson 15ae41c2db Issue #7048: logb should round its result when that result doesn't fit

the most recent set of testcases from the Decimal Specification site;
those testcases will be updated shortly.)

Neal Norwitz 18aa388ca0 Fix:
* 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).

TBR=barry
TESTED=./python -E -tt ./Lib/test/regrtest.py -uall (both debug and opt modes)
  in opt mode:
  valgrind -q --leak-check=yes --suppressions=Misc/valgrind-python.supp \
    ./python -E -tt ./Lib/test/regrtest.py -uall,-bsddb,-compiler \
                        -x test_logging test_ssl test_multiprocessing
  valgrind -q --leak-check=yes --suppressions=Misc/valgrind-python.supp \
    ./python -E -tt ./Lib/test/regrtest.py test_multiprocessing
  for i in `seq 1 4000` ; do
    LD_PRELOAD=~/local/lib/libfailmalloc.so FAILMALLOC_INTERVAL=$i \
        ./python -c pass
  done

At least some of these fixes should probably be backported to 2.5.

Mark Dickinson 70c3289085 Replace occurrences of '\d' with '[0-9]' in Decimal regex, to make sure
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.

Mark Dickinson 71f3b85497 Make sure that Context traps and flags dictionaries have values 0 and 1

Mark Dickinson 8aca9d032e Some very minor changes to decimal.py in Python 2.6, aimed
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
