Extend deprecation warning period for bitwise inversion on bool type #122982
Description
Feature or enhancement
Proposal:
Since Python 3.12, attempting to use bitwise inversion on a bool type is raises a DeprecationWarning:
Python 3.12.4 (main, Jun 6 2024, 18:26:44) [Clang 15.0.0 (clang-1500.3.9.4)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> a = True
>>> ~a
<stdin>:1: DeprecationWarning: Bitwise inversion '~' on bool is deprecated. This returns the bitwise inversion of the underlying int object and is usually not what you expect from negating a bool. Use the 'not' operator for boolean negation or ~int(x) if you really want the bitwise inversion of the underlying int.

>>>I have a PR ready.

It's deprecated, but why should it be removed now?
encukou commentedon Aug 14, 2024
Oh, I see the plan to remove it in 3.14 is in the docs, but not all the places it should be :(

I think the removal might affect a number of users (e.g. see comments on #103487); I'd vote for extending the deprecation period beyond the 2 year minimum

I've read these comments and I agree with your opinion. I'll close the PR and open a new one to properly document the deprecation.

It is not necessary to close the PR. It can simply be postponed for few years.

I've changed the title of the issue to highlight the fact that we are not removing it for now. We will change it later when we'll eventually remove it (just for tracking purposes)

Can't this be closed now?
picnixz commentedon Sep 26, 2024
Mmmh. Yes. We'll open another issue if we want to really deprecate the behaviour.
