[issue20443] __code__. co_filename should always be an absolute path

STINNER Victor added the comment: Michel Desmoulin: "The relevance of the use case isn't the problem. Even if people had been using it wrong for all this time, the update is still going to break their code if they did use it this way. And if it was possible, of course many people did." You

[issue36541] Make lib2to3 grammar more closely match Python

Peter Ludemann added the comment: Re: breakage due to changes in structure (https://bugs.python.org/issue36541#msg339669) ... this has already happened in the past (e.g., type annotations and async). It's probably a good idea to add some documentation that structure changes can be expected

Peter Ludemann added the comment: Should I just close this? (I didn't find https://bugs.python.org/issue36541 when I searched, possibly because I used "2to3" instead of "lib2to3" in my search.) -- ___ Python tracker

[issue38553] Document functools.cached_property supports value updating and clearing

[issue38553] Document functools.cached_property supports value updating and clearing

Laurie Opperman added the comment: @hongweipeng What can be solved? Do you mean `functools.cached_property` should inherit `property`? First, this would break existing code dependant on the functionality of `functools.cached_property` (admittedly, Python 3.8 was release less than two weeks a

[issue38483] [venv] Add ~/.venvrc to change module defaults

Laurie Opperman added the comment: ".xrc" usually means a file to be run (by a shell) at shell start, and therefore is a script of command to run ("rc" seems to come from "runcom", ie run commands). INI files usually have a ".ini" or ".cfg" suffix. `virtualenv`, for example, used an INI
