Neal Norwitz 47f0ffa7ee Fix a couple of ssize-t issues reported by Alexander Belopolsky on python-dev 2006-08-21 18:44:09 +00:00
Neal Norwitz 03ee62c352 Move assert to after NULL check, otherwise we deref NULL in the assert.

Thomas Heller b4a0cf17c4 Remove the special casing of Py_None when converting the return value
of the Python part of a callback function to C.  If it cannot be
converted, call PyErr_WriteUnraisable with the exception we got.
Before, arbitrary data has been passed to the calling C code in this
case.

(I'm not really sure the NEWS entry is understandable, but I cannot
find better words)
2006-08-16 15:10:12 +00:00
Thomas Heller b0aa98fd4f The __repr__ method of a NULL py_object does no longer raise an
exception.  Remove a stray '?' character from the exception text
when the value is retrieved of such an object.

Includes tests.
2006-08-16 14:07:44 +00:00
Thomas Heller d32e616722 Add commented assert statements to check that the result of
PyObject_stgdict() and PyType_stgdict() calls are non-NULL before
dereferencing the result.  Hopefully this fixes what klocwork is
complaining about.

Fix a few other nits as well.

Thomas Heller ef8d513d62 Patch #1536908: Add support for AMD64 / OpenBSD.

2006-08-14 16:17:41 +00:00
Thomas Heller 867200483b Apply the patch #1532975 plus ideas from the patch #1533481.
ctypes instances no longer have the internal and undocumented
'_as_parameter_' attribute which was used to adapt them to foreign
function calls; this mechanism is replaced by a function pointer in
the type's stgdict.

In the 'from_param' class methods, try the _as_parameter_ attribute if
other conversions are not possible.

This makes the documented _as_parameter_ mechanism work as intended.

Change the ctypes version number to 1.0.1.

Neal Norwitz 8a87f5d37e Patch #1538606, Patch to fix __index__() clipping.
I modified this patch some by fixing style, some error checking, and adding
XXX comments.  This patch requires review and some changes are to be expected.
I'm checking in now to get the greatest possible review and establish a
baseline for moving forward.  I don't want this to hold up release if possible.

Neal Norwitz b45f351832 I'm not sure why this code allocates this string for the error message.

Neal Norwitz 6f5ff3f3eb Klocwork made another run and found a bunch more problems.
This is the first batch of fixes that should be easy to verify based on context.

function's result cannot be converted.

Tim Peters 5566e96830 defdict_reduce(): Plug leaks.
We didn't notice these before because test_defaultdict didn't

Neal's next refleak run then showed test_defaultdict leaking
9 references on each run.  That's repaired by this checkin.
2006-07-28 00:23:15 +00:00
Barry Warsaw 00decd7835 Patch #1520294: Support for getset and member descriptors in types.py,
inspect.py, and pydoc.py.  Specifically, this allows for querying the type of
an object against these built-in C types and more importantly, for getting
their docstrings printed in the interactive interpreter's help() function.

This patch includes a new built-in module called _types which provides
definitions of getset and member descriptors for use by the types.py module.
These types are exposed as types.GetSetDescriptorType and
types.MemberDescriptorType.  Query functions are provided as
inspect.isgetsetdescriptor() and inspect.ismemberdescriptor().  The
implementations of these are robust enough to work with Python implementations
other than CPython, which may not have these fundamental types.

The patch also includes documentation and test suite updates.

I commit these changes now under these guiding principles:

1. Silence is assent.  The release manager has not said "no", and of the few
   people that cared enough to respond to the thread, the worst vote was "0".

2. It's easier to ask for forgiveness than permission.

3. It's so dang easy to revert stuff in svn, that you could view this as a
   forcing function. :)

Windows build patches will follow.

Brett Cannon caebe22038 Fix bug #1520914. Starting in 2.4, time.strftime() began to check the bounds
of values in the time tuple passed in.  Unfortunately people came to rely on
undocumented behaviour of setting unneeded values to 0, regardless of if it was
within the valid range.  Now those values force the value internally to the
minimum value when 0 is passed in.

Thomas Heller f780be4239 Add a new function uses_seh() to the _ctypes extension module. This

Currently, only MSVC supports SEH.

Fix the test so that it doesn't crash when run with MingW compiled
_ctypes.  Note that two tests are still failing when mingw is used, I
suspect structure layout differences and function calling conventions
between MSVC and MingW.
