Infinite Loop in Positron Python When Redirecting sys.stdout in Iterating (Not sure about title)

System details:

Positron and OS details:

Positron Version: 2025.02.0 (Universal) build 79
Code - OSS Version: 1.96.0

V8: 12.8.374.38-electron.0
OS: Darwin arm64 24.0.0

Interpreter details:

Python 3.11.10

Describe the issue:

The following code causes Positron Python to enter an infinite loop.

import gc
import sys

with open("gc_objects_Positron.txt", "w", encoding="utf-8") as f:
    sys.stdout = f
    for obj in gc.get_objects():
        print(obj)
    sys.stdout = sys.__stdout__

Expected or desired behavior:

In terminal, ipython won't happen.

Were there any error messages in the UI, Output panel, or Developer Tools console?

A very very large output is generated?

Thank you for your bug report, @ZhimingYe!

I am able to reproduce locally and am moving this issue to triage for prioritization.

(Note that the provided sample code runs quickly to completion when run outside Positron)

Let's see if this works in a Jupyter notebook and/or in ipython.

@juliasilge Thanks for your reply! In this issue's "Expected or desired behavior" part I used ipython for testing, and there wasn't any bug. But I agree with that this is not a high priority issue, and can be moved to milestones after the first stable version is released😄
