[issue36455] collections.abc.Sequence doesn't support reflection/introspection

James Edwards added the comment: Edit conflict -- indeed -- self closing. --- I should point out that this could be fixed with something like the following: @classmethod def __subclasshook__(cls, C): if cls is Sequence: return _check_methods(C, "__reversed__", "__

[issue36457] functools.singledispatchmethod interacts poorly with subclasses

New submission from Tim Mitchell : The new functools.singledispatchmethod (issue32380) class interacts poorly with subclasses. There is no way for a sub-class to override or extend the dispatch registry. E.g. class BaseVistor: @singledispatchmethod def visit(self, obj): raise Value

[issue36458] Compile errors --without-threads

New submission from patrik : Compiling python 3.6.8 configured with --without-threads (no other options) fails, with undefined references to PyGILState_GetThisThreadState in pylifecycle.c, and PyGILState_Ensure and PyGILState_Release in object.c. I used Louis' fix from issue #24784 in pylifec

patrik added the comment: Not a problem. I wanted to record the issue just in case someone else encounters it, and also because there seems to have been a history of issues with the no-threads option. Happy to hear its sorted in 3.7. -- ___ Python

[issue36459] A possible double PyMem_FREE() due to tokenizer.c's tok_nextc()

New submission from Zackery Spytz : Commit cb90c89de14aab636739b3e810cf949e47b54a0c added a PyMem_FREE(tok->buf) call in tok_nextc() if a PyMem_REALLOC() call fails. This will cause a double free when PyTokenizer_Free() is called on the tokenizer state. -- components: Interpreter Core

[issue35983] tp_dealloc trashcan shouldn't be called for subclasses

Serhiy Storchaka added the comment: In your example you can add PyTypeObject *tp = Py_TYPE(self); Py_TYPE(self) = &PyList_Type; if (PyType_GetFlags(tp) & Py_TPFLAGS_HEAPTYPE) { Py_DECREF(tp); } before calling PyList_Type.tp_dealloc(). It is possible to add such code d
