* 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.

the stuff in here is included into relevant places; see the individual
source files for details.
--------------------------------------------------------------------
the following defines used by the different modules:
STRINGLIB_CHAR
the type used to hold a character (char or Py_UNICODE)
STRINGLIB_EMPTY
a PyObject representing the empty string
int STRINGLIB_CMP(STRINGLIB_CHAR*, STRINGLIB_CHAR*, Py_ssize_t)
compares two strings. returns 0 if they match, and non-zero if not.
Py_ssize_t STRINGLIB_LEN(PyObject*)
returns the length of the given string object (which must be of the
right type)
PyObject* STRINGLIB_NEW(STRINGLIB_CHAR*, Py_ssize_t)
creates a new string object
STRINGLIB_CHAR* STRINGLIB_STR(PyObject*)
returns the pointer to the character data for the given string
object (which must be of the right type)
