From 1fe5fe419ec98934bf0447e50fe8c28adeabaee5 Mon Sep 17 00:00:00 2001 From: zeripath Date: Sat, 10 Apr 2021 13:08:30 +0100 Subject: [PATCH] Always set the merge base used to merge the commit (#15352) (#15385) Backport #15352 The issue is that the TestPatch will reset the PR MergeBase - and it is possible for TestPatch to update the MergeBase whilst a merge is ongoing. The ensuing merge will then complete but it doesn't re-set the MergeBase it used to merge the PR. Fixes the intermittent error in git test.
