From b1c5747717c1273c0792d2d8742aeaaddbad1361 Mon Sep 17 00:00:00 2001 From: Andy Neff Date: Tue, 9 Dec 2025 10:45:57 -0500 Subject: [PATCH 1/5] Stop using unoffical API for rmtree - Vastly simplify rmtree by just using shutil.rmtree many times instead of trying to be super efficient and doing it all at once.
