* bpo-33738: Fix macros which contradict PEP 384 (GH-7477)Christian Tismer2018-06-092-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During development of the limited API support for PySide, we saw an error in a macro that accessed a type field. This patch fixes the 7 errors in the Python headers. Macros which were not written as capitals were implemented as function. To do the necessary analysis again, a script was included that parses all headers and looks for "->tp_" in serctions which can be reached with active limited API. It is easily possible to call this script as a test. Error listing: ../../Include/objimpl.h:243 #define PyObject_IS_GC(o) (PyType_IS_GC(Py_TYPE(o)) && \ (Py_TYPE(o)->tp_is_gc == NULL || Py_TYPE(o)->tp_is_gc(o))) Action: commented only ../../Include/objimpl.h:362 #define PyType_SUPPORTS_WEAKREFS(t) ((t)->tp_weaklistoffset > 0) Action: commented only ../../Include/objimpl.h:364 #define PyObject_GET_WEAKREFS_LISTPTR(o) \ ((PyObject **) (((char *) (o)) + Py_TYPE(o)->tp_weaklistoffset)) Action: commented only ../../Include/pyerrors.h:143 #define PyExceptionClass_Name(x) \ ((char *)(((PyTypeObject*)(x))->tp_name)) Action: implemented function ../../Include/abstract.h:593 #define PyIter_Check(obj) \ ((obj)->ob_type->tp_iternext != NULL && \ (obj)->ob_type->tp_iternext != &_PyObject_NextNotImplemented) Action: implemented function ../../Include/abstract.h:713 #define PyIndex_Check(obj) \ ((obj)->ob_type->tp_as_number != NULL && \ (obj)->ob_type->tp_as_number->nb_index != NULL) Action: implemented function ../../Include/abstract.h:924 #define PySequence_ITEM(o, i)\ ( Py_TYPE(o)->tp_as_sequence->sq_item(o, i) ) Action: commented only

* Replace _PyGC_REFS macros with higher level macros (GH-6852)INADA Naoki2018-05-171-5/+3

* bpo-33012: Fix invalid function casts for long_long. (GH-6652)Serhiy Storchaka2018-04-301-17/+25

* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-2925-164/+164
| | | | | | | | | (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-33041: Fix downcast warning on Windows (#6595)Victor Stinner2018-04-271-1/+1

* bpo-33312: Fix clang ubsan out of bounds warnings in dict. (GH-6537)Gregory P. Smith2018-04-202-24/+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-33041: Rework compiling an "async for" loop. (#6142)Serhiy Storchaka2018-03-231-12/+9
| | | | | | | | * Added new opcode END_ASYNC_FOR. * Setting global StopAsyncIteration no longer breaks "async for" loops. * Jumping into an "async for" loop is now disabled. * Jumping out of an "async for" loop no longer corrupts the stack. * Simplify the compiler.
* bpo-32374: m_traverse may be called with m_state=NULL (GH-5140)Marcel Plch2018-03-171-0/+21
| | | | | Multi-phase initialized modules allow m_traverse to be called while the module is still being initialized, so module authors may need to account for that.

* bpo-32703: Fix coroutine resource warning in case where there's an error ↵Yury Selivanov2018-01-291-6/+7
| | | | | (GH-5410) The commit removes one unnecessary "if" clause in genobject.c. That "if" clause was masking un-awaited coroutines warnings just to make writing unittests more convenient.

* 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().

* bpo-32028: Fix suggestions for indented print statements (GH-4688)Sanyam Khurana2018-01-201-5/+11
| | | | | | | The suggested replacement for print statements previously failed to account for leading whitespace and hence could end up including unwanted text in the proposed call to the print builtin. Patch by Sanyam Khurana.
