From af1aa4b05de3e88918869b8867e182df09010574 Mon Sep 17 00:00:00 2001 From: Benedikt Spranger Date: Thu, 7 May 2020 00:12:27 +0200 Subject: [PATCH 1/2] Fix key expire function The key expire function failed with RuntimeError: dictionary changed size during iteration Python 3 did not act on a copy while iterating over a dictionary any more. Instead a iterator is used. Removing elements from the dictionary will fail and throw the given exception. Iterate over a copy of the dictionary.
