From 9ddd5b883b0221d80392a914eb621ea680476e75 Mon Sep 17 00:00:00 2001 From: Patrick Steinhardt Date: Thu, 2 Nov 2023 09:46:41 +0100 Subject: [PATCH] t: allow skipping expected object ID in `ref-store update-ref` We require the caller to pass both the old and new expected object ID to our `test-tool ref-store update-ref` helper. When trying to update a symbolic reference though it's impossible to specify the expected object ID, which means that the test would instead have to force-update the reference. This is currently impossible though. Update the helper to optionally skip verification of the old object ID in case the test passes in an empty old object ID as input.
