Pauli Virtanen 07f1658aa0 bpo-10746: Fix ctypes PEP 3118 type codes for c_long, c_bool, c_int (#31)
Ctypes currently produces wrong pep3118 type codes for several types.
E.g. memoryview(ctypes.c_long()).format gives "<l" on 64-bit platforms,
but it should be "<q" instead for sizeof(c_long) == 8

The problem is that the '<>' endian specification in the struct syntax
also turns on the "standard size" mode, which makes type characters have
a platform-independent meaning, which does not match with the codes used
internally in ctypes.  The struct module format syntax also does not
allow specifying native-size non-native-endian items.

This commit adds a converter function that maps the internal ctypes
codes to appropriate struct module standard-size codes in the pep3118
format strings. The tests are modified to check for this.

Serhiy Storchaka f7eae0adfc [security] bpo-13617: Reject embedded null characters in wchar* strings. (#2302)
Based on patch by Victor Stinner.

Add private C API function _PyUnicode_AsUnicode() which is similar to
PyUnicode_AsUnicode(), but checks for null characters.

Serhiy Storchaka 0b3ec19225 Use NULL rather than 0. (#778)
There was few cases of using literal 0 instead of NULL in the context of
pointers.  While this was a legitimate C code, using NULL rather than 0 makes
the code clearer.

orenmn 1bea762d9e bpo-28129: fix ctypes crashes (#386)
* init commit, with initial tests for from_param and fields __set__ and __get__, and some additions to from_buffer and from_buffer_copy

* added the rest of tests and patches. probably only a first draft.

* removed trailing spaces

* replace ctype with ctypes in error messages

* change back from ctypes instance to ctype instance

Vinay Sajip a86339b83f Fixed bpo-29565: Corrected ctypes passing of large structs by value on Windows AMD64. (#168)
* Fixed bpo-29565: Corrected ctypes passing of large structs by value.

Added code and test to check that when a structure passed by value
is large enough to need to be passed by reference, a copy of the
original structure is passed. The callee updates the passed-in value,
and the test verifies that the caller's copy is unchanged. A similar
change was also added to the test added for bpo-20160 (that test was
passing, but the changes should guard against regressions).

* Reverted unintended whitespace changes.

Victor Stinner 5670764812 Use _PyObject_CallMethodIdObjArgs() in _ctypes
Issue #28915: Replace _PyObject_CallMethodId() with
_PyObject_CallMethodIdObjArgs() in unpickle(). _PyObject_CallMethodIdObjArgs()
avoids the creation of a temporary tuple and doesn't have to parse a format
string.

Replace _PyObject_CallMethodId() with _PyObject_GetAttrId()+PyObject_Call() for
the second call since it requires to "unpack" a tuple.

Add also a check in the type of the second parameter (state): it must be a
tuple.

Benjamin Peterson 6d999803a0 remove long double from ctypes value union
It is unused. It also forces a 16-byte alignment, which creates problems because
Python's allocator only uses 8-byte alignment.
