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 \

valgrind -q --leak-check=yes --suppressions=Misc/valgrind-python.supp \

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.

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

Major change in the internal structure of the Decimal
...
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.

The constructor from tuple was way too permissive: it allowed bad
...
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.

Made the various is_* operations return booleans. This was discussed
...
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).
