* bpo-37140: Fix StructUnionType_paramfunc() (GH-15612)Victor Stinner2019-08-301-6/+45
| | | | | | | | | | | | Fix a ctypes regression of Python 3.8. When a ctypes.Structure is passed by copy to a function, ctypes internals created a temporary object which had the side effect of calling the structure finalizer (__del__) twice. The Python semantics requires a finalizer to be called exactly once. Fix ctypes internals to no longer call the finalizer twice. Create a new internal StructParam_Type which is only used by _ctypes_callproc() to call PyMem_Free(ptr) on Py_DECREF(argument). StructUnionType_paramfunc() creates such object.

| | | | | | | The final addition (cur += step) may overflow, so use size_t for "cur". "cur" is always positive (even for negative steps), so it is safe to use size_t here. Co-Authored-By: Martin Panter <vadmium+py@gmail.com>

* bpo-27643 - skip test_ctypes test case with XLC compiler. (GH-5164)Michael Felt2018-12-261-0/+4
| | | | | | | | | This test case needs "signed short" bitfields, but the IBM XLC compiler (on AIX) does not support this. Skip the code and test when AIX and XLC are used. Use __xlc__ as identifier to detect the XLC compiler.

* bpo-10746: Fix ctypes PEP 3118 type codes for c_long, c_bool, c_int (#31)Pauli Virtanen2017-08-281-28/+55
| | | | | | | | | | | | | | | 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.
* [security] bpo-13617: Reject embedded null characters in wchar* strings. (#2302)Serhiy Storchaka2017-06-281-0/+2
| | | | | | | Based on patch by Victor Stinner. Add private C API function _PyUnicode_AsUnicode() which is similar to PyUnicode_AsUnicode(), but checks for null characters.
* bpo-30708: Check for null characters in PyUnicode_AsWideCharString(). (#2285)Serhiy Storchaka2017-06-271-2/+2
| | | | | Raise a ValueError if the second argument is NULL and the wchar_t\* string contains null characters.

* Fixed bpo-29565: Corrected ctypes passing of large structs by value on ↵Vinay Sajip2017-02-202-0/+34
| | | | | | | | | | | | | | | 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.
