[issue44524] __name__ attribute in typing module

Ken Jin added the comment: > This PRs herein have created a situation wherein the > `__name__`/`__qualname__` attributes of certain typing objects can be `None`. > Is this behavior intentional? The affected objects are special forms which can hold types, so Union[], TypeGuard[], and

[issue44803] change tracemalloc.BaseFilter to an abstract class

Anton Grübel added the comment: Even it is a private method, it is essential, when you use Snapshot.filter_traces(). Creating a Filter without implementing this method will just result in a runtime error.

[issue44837] os.symlink arg names are bad

krey added the comment: OK, let's ignore the analogy. Everywhere else I've seen, arrows (or directed edges in a graph) point as SOURCE -> TARGET SOURCE -> DESTINATION (TARGET and DESTINATION are synonymous in this context) An example from math:

[issue44837] os.symlink arg names are bad

Steven D'Aprano added the comment: There is nothing wrong with saying Create a symbolic link pointing to `src` named `dst`. That is grammatically correct English. We could say "create a sym link called dst pointing to src" but they mean exactly the same thing. And given that the order

[issue44301] Is there a way to provide destructor for module written using C API?

Petr Viktorin added the comment: I see that I wrote "counts" rather than "cycles" before; that line should be: The clear function is used to break reference cycles. In this case, there are no reference cycles to be broken, so it is not called. Thanks to Pablo for the review & Łukasz for

[issue44803] change tracemalloc.BaseFilter to an abstract class

STINNER Victor added the comment: I don't see the benefit of the PR 27527. "BaseFilter" contains "Base" in its name and its only *private* method raises NotImplementedError. Maybe my design mistake (I wrote the tracemalloc module) was to expose it in the first place. I suggest to leave the

[issue44837] os.symlink arg names are bad

New submission from krey : From: https://docs.python.org/3/library/os.html os.symlink(src, dst, target_is_directory=False, *, dir_fd=None) Create a symbolic link pointing to `src` named `dst`. It's a bit like saying find(needle, haystack) Finds `haystack` in `needle` If you look

[issue44749] LOAD_NAME not using PyObject_GetItem when globals() is a dict subclass

Douglas Raillard added the comment: I ended up with a slightly different API that allows me to preemptively set some global names before the code runs in the module, so my use case sort of vanished. I don't think there is a real need of beating the dead horse here. My only suggestion on the
