[issue45520] Frozen dataclass deep copy doesn't work with __slots__

Josh Rosenberg added the comment: You're right that in non-dataclass scenarios, you'd just use __slots__. The slots=True thing was necessary for any case where any of the dataclass's attributes have default values (my_int: int = 0), or are defined with fields (my_list: list =

[issue25222] 3.5.0 regression - Fatal Python error: Cannot recover from stack overflow

Irit Katriel added the comment: There was work on recursion in recent versions and the Fatal Error is less likely now. We will not investigate recursion issues on 3.5, so I will close this and request that you create a new issue if you have problem with a current Python version. --

[issue45113] [subinterpreters][C API] Add a new function to create PyStructSequence from Heap.

Petr Viktorin added the comment: Ah, sorry, I overlooked the flags. This does beg the question: what else from PyType_Spec will be needed? I guess we don't want to allow additional slots/methods. (Combining them would be hard anyway; if someone needs them they should make a subclass.) So it

[issue4304] build mode which fails for build failures in extensions

[issue45524] Cross-module dataclass inheritance breaks get_type_hints

New submission from Aidan Clark : [I believe this is fundamentally a dataclass version of https://bugs.python.org/issue41249] When using `from __future__ import annotations`, calling get_type_hints on the constructor of a dataclass B which inherits from a dataclass A defined in another

[issue45525] PyType_Spec basicsize/itemsize should allow -1 for "inherit"

New submission from Petr Viktorin : For cases where you aren't adding new C-level state, especially if don't have the superclass' struct available, it would be good to allow inheriting basicsize/itemsize from the superclass. (SuperType->tp_size is not easily usable for the same reason

Sergei Lebedev added the comment: I think the example has a minor typo. The crash is reproducible on 3.9 if the last line in bar.py is typing.get_type_hints(B.__init__) instead of typing.get_type_hints(B) -- ___ Python tracker

[issue45527] Reduce overhead for cache hits in specialized opcodes.

New submission from Mark Shannon : Every time we get a cache hit in, e.g. LOAD_ATTR_CACHED, we increment the saturating counting. Takes a dependent load and a store, as well as the shift. For fast instructions like BINARY_ADD_FLOAT, this represents a significant portion of work done in the
