library.
Remove most files from _ctypes/libffi_msvc, only two include files
stay (updated from _ctypes/libffi/...). Other files are used in the
cross-platform _ctypes/libffi directory.

Work in progress. 2 tests fail on x86/win32 because the stack
checking code in ffi_call_win32 is not yet implemented.
Remove most files from _ctypes/libffi_msvc, only two include files
stay (updated from _ctypes/libffi/...). Other files are used in the
cross-platform _ctypes/libffi directory.

On Windows, ctypes does no longer check the stack before and after
calling a foreign function.
This allows to use the unmodified libffi library.

Most uses of PyCode_New found by http://www.google.com/codesearch?q=PyCode_New
are trying to build an empty code object, usually to put it in a dummy frame
object. This patch adds a PyCode_NewEmpty wrapper which lets the user specify
just the filename, function name, and first line number, instead of also
requiring lots of code internals.
Replace ffi_call_STDCALL and ffi_call_SYSV by a ffi_call_x86 function
that cleans up the stack when FFI_SYSV is used, and does nothing for
FFI_STDCALL.
Remove libffi_msvc\win32.S, which is out of date and also unused; it
was only used for building ctypes with the MingW compiler.
* 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.
