From c48b8f8db8625fe543691e3306f4226435f77ec8 Mon Sep 17 00:00:00 2001 From: "Gregory P. Smith" Date: Sat, 20 Jan 2024 12:09:50 -0800 Subject: [PATCH] Remove the non-test Lib/test/time_hashlib.py. (#114354) I believe I added this while chasing some performance of hash functions when I first created hashlib. It hasn't been used since, is frankly trivial, and not a test. --- Lib/test/time_hashlib.py | 88 ---------------------------------------- 1 file changed, 88 deletions(-) delete mode 100644 Lib/test/time_hashlib.py diff --git a/Lib/test/time_hashlib.py b/Lib/test/time_hashlib.py deleted file mode 100644 index 55ebac62912fe1..00000000000000 --- a/Lib/test/time_hashlib.py +++ /dev/null @@ -1,88 +0,0 @@ -# It's intended that this script be run by hand.
