* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-16/+16
| | | | | | | | | (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument.

* bpo-33312: Fix clang ubsan out of bounds warnings in dict. (GH-6537)Gregory P. Smith2018-04-201-15/+12
| | | | | | | | | | | | | | | | | | | | Fix clang ubsan (undefined behavior sanitizer) warnings in dictobject.c by adjusting how the internal struct _dictkeysobject shared keys structure is declared. This remains ABI compatible. We get rid of the union at the end of the struct being used for conveinence to avoid typecasting in favor of char[] variable length array at the end of a struct. This is known to clang to be used for variable sized objects and will not cause an undefined behavior problem. Similarly, char arrays do not have strict aliasing undefined behavior when cast. PEP-007 does not currently list variable length arrays (VLAs) as allowed in our subset of C99. If this turns out to be a problem, the fix to this is to change the char `dk_indices[]` into `dk_indices[1]` and restore the three size computation subtractions this change removes: `- Py_MEMBER_SIZE(PyDictKeysObject, dk_indices)` If this works as is I'll make a separate PR to update PEP-007.

* bpo-18533: Avoid RecursionError from repr() of recursive dictview (#4823)bennorth2018-01-261-4/+12
| | | | | | | | | | | | | | | | | dictview_repr(): Use a Py_ReprEnter() / Py_ReprLeave() pair to check for recursion, and produce "..." if so. test_recursive_repr(): Check for the string rather than a RecursionError. (Test cannot be any tighter as contents are implementation-dependent.) test_deeply_nested_repr(): Add new test, replacing the original test_recursive_repr(). It checks that a RecursionError is raised in the case of a non-recursive but deeply nested structure. (Very similar to what test_repr_deep() in test/test_dict.py does for a normal dict.) OrderedDictTests: Add new test case, to test behavior on OrderedDict instances containing their own values() or items().

| | | | | | | | Make a non-Py_DEBUG, asserts-enabled build of CPython possible. This means making sure helper functions are defined when NDEBUG is not defined, not just when Py_DEBUG is defined. Also fix a division-by-zero in obmalloc.c that went unnoticed because in Py_DEBUG mode, elsize is never zero.

| | | | | | | | | | | Issue #29311: dict.get() and dict.setdefault() methods now use Argument Clinic to parse arguments. Their calling convention changes from METH_VARARGS to METH_FASTCALL which avoids the creation of a temporary tuple. The signature of docstrings is also enhanced. For example, get(...) becomes: get(self, key, default=None, /)

This change is part of the fastcall project. The change on listsort() is related to the issue #23507.
