Mark Dickinson 6d8effb1fc Issue #7633: Context method in the decimal module (with the exception
of the 'canonical' and 'is_canonical' methods) now consistently accept
integer arguments wherever a Decimal instance is accepted.  Thanks
Juan José Conti for the patch.

Mark Dickinson 15ae41c2db 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.)

Thanks Mark Dickinson.

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
(as documented) rather than True and False.

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
