gh-139951: Test on GC collection disabled if threshold is zero by efimov-mikhail · Pull Request #140304 · python/cpython

efimov-mikhail · 2025-10-18T17:07:04Z

This PR just adds small test.
I've noticed that there's no such test because CI is green for this PR:
#140262, but it has such a flaw.

Issue: Potentially serious regression in garbage collector performance in Python 3.14 #139951

sergey-miryanov · 2025-10-18T17:12:29Z

 gc.enable()

+ # Ensure that setting *threshold0* to zero disables collection.
+ @gc_threshold(0, 0, 0)


It is better to set gc_threshold(0) to keep other values defaults.

sergey-miryanov

Looks good to me. Overall, I believe it is worth to add such test.

markshannon

Looks good, thanks.
