* bpo-33312: Fix clang ubsan out of bounds warnings in dict. (GH-6537) (GH-6543)Miss Islington (bot)2018-04-202-24/+14
| | | | | | | | | | | | | | | | | | | | | 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().
