* bpo-35529: Fix a reference counting bug in PyCFuncPtr_FromDll(). (GH-11229)Miss Islington (bot)2018-12-201-5/+8
| | | | | | | "dll" would leak if an error occurred in _validate_paramflags() or GenericPyCData_new(). (cherry picked from commit d77d97c9a1f593fe161afab97e2a3e2292ab88b9) Co-authored-by: Zackery Spytz <zspytz@gmail.com>
* [2.7] bpo-35441: Remove dead and buggy code related to PyList_SetItem(). ↵Serhiy Storchaka2018-12-194-19/+21
| | | | | | | | | | | | | | (GH-11033) (GH-11234) In _localemodule.c and selectmodule.c, remove dead code that would cause double decrefs if run. In addition, replace PyList_SetItem() with PyList_SET_ITEM() in cases where a new list is populated and there is no possibility of an error. In addition, check if the list changed size in the loop in array_array_fromlist().

| | | | | | | | | | | | | | AMD64 (GH-168) (GH-8625) 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).
