[PATCH v2 1/9] t: allow skipping expected object ID in `ref-store update-ref`

From
Patrick Steinhardt <ps@pks.im>
Date
Oct 24, 2023, 14:04 UTC
Message-ID
<c868198f8c1e0ddeb6577efdf741623584653633.1698156169.git.ps@pks.im>
In-Reply-To
<cover.1698156169.git.ps@pks.im>

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.
