* bpo-37140: Fix StructUnionType_paramfunc() (GH-15612)Victor Stinner2019-08-301-14/+59
| | | | | | | | | | | | 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.

* bpo-36946: Fix possible signed integer overflow when handling slices. (GH-13375)Zackery Spytz2019-05-171-2/+4
| | | | | | | 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-36594: Fix incorrect use of %p in format strings (GH-12769)Zackery Spytz2019-05-062-6/+6

* bpo-35947: Update Windows to the current version of libffi (GH-11797)Paul Monson2019-03-2914-2291/+39
| | | We now use a pre-built libffi binary from our binaries repository, and no longer vendor the full implementation.
* bpo-36421: Fix a possible double decref in _ctypes.c's PyCArrayType_new(). ↵Zackery Spytz2019-03-251-0/+1
| | | | | | | (GH-12530) Set type_attr to NULL after the assignment to stgdict->proto (like what is done with stgdict after the Py_SETREF() call) so that it is not decrefed twice on error.

| | | | | lock (GH-7789) LoadLibrary, GetProcAddress, FreeLibrary and GetModuleHandle acquire the system loader lock. Calling these while holding the GIL will cause a deadlock on the rare occasion that another thread is detaching and needs to destroy its thread state at the same time.
* bpo-35847: RISC-V needs CTYPES_PASS_BY_REF_HACK (GH-11694)Andreas Schwab2019-01-291-1/+1
| | | | | | This fixes the ctypes.test.test_structures.StructureTestCase test. https://bugs.python.org/issue35847
* bpo-27643 - skip test_ctypes test case with XLC compiler. (GH-5164)Michael Felt2018-12-261-4/+14
| | | | | | | | | 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-35529: Fix a reference counting bug in PyCFuncPtr_FromDll(). (GH-11229)Zackery Spytz2018-12-201-5/+8
| | | | | "dll" would leak if an error occurred in _validate_paramflags() or GenericPyCData_new().

| | | | | | | | | | | | * bpo-31572: Get rid of PyObject_HasAttrString() in ctypes. * Fix error handling for _pack_. * Don't silence errors when look up in a dict. * Use _PyObject_LookupAttrId(). * More changes.
* bpo-10320: Replace nonstandard sprintf() length modifier in ctypes' ↵Zackery Spytz2018-12-031-1/+1
| | | | | PyCArg_repr(). (GH-10853) Use "ll" instead of the nonstandard "q".
* bpo-33029: Fix signatures of getter and setter functions. (GH-10746)Serhiy Storchaka2018-11-271-17/+17
| | | Fix also return type for few other functions (clear, releasebuffer).
* bpo-35214: Add _Py_ prefix to MEMORY_SANITIZER def. (GH-10503)Gregory P. Smith2018-11-131-2/+2
| | | | Rename our new MEMORY_SANITIZER define to _Py_MEMORY_SANITIZER. Project based C Preprocessor namespacing at its finest. :P
* bpo-35214: Initial clang MemorySanitizer support (GH-10479)Gregory P. Smith2018-11-121-0/+11
| | | | | | | | | | Adds configure flags for msan and ubsan builds to make it easier to enable. These also encode the detail that address sanitizer and memory sanitizer should disable pymalloc. Define MEMORY_SANITIZER when appropriate at build time and adds workarounds to existing code to mark things as initialized where the sanitizer is otherwise unable to determine that. This lets our build succeed under the memory sanitizer. not all tests pass without sanitizer failures yet but we're in pretty good shape after this.
* bpo-29843: raise AttributeError if given negative _length_ (GH-10029)Tal Einat2018-10-221-5/+20
| | | | | | | | Raise ValueError OverflowError in case of a negative _length_ in a ctypes.Array subclass. Also raise TypeError instead of AttributeError for non-integer _length_. Co-authored-by: Oren Milman <orenmn@gmail.com>
