From 7201e54e5ffed8a1506b76b79ce98b15687d4fd7 Mon Sep 17 00:00:00 2001 From: zeripath Date: Sat, 29 Jan 2022 15:35:36 +0000 Subject: [PATCH] Attempt to prevent intermittent failure TestGit/xxx/BranchProtectMerge/MergePR (#18451) Backport #18451 One of the repeated intermittent failures we see in testing is a failure due to branches not being ready to merge. Prior to the immediate queue implementation we would attempt to flush all the queues and this would prevent the issue. However, the immediate queue is not flushable so the flushall is not successful at preventing this. This PR proposes an alternative solution - wait some time and try again up to 5 times. If this fails then there is a genuine issue and we should fail.
