GeezerVison is showing github.com — gh-76785: Handle Legacy Interpreters Properly by ericsnowcurrently · Pull Request #117490 · python/cpython
Conversation
This is similar to the situation with threading._DummyThread. The methods (incl. __del__()) of interpreters.Interpreter objects must be careful with interpreters not created by interpreters.create(). The simplest thing is to disable any method that modifies or runs in the interpreter. As part of this, the runtime keeps track of where an interpreter was created. We also handle interpreter "refcounts" properly.
Sorry, something went wrong.
Uh oh!
