From: Jon Simons Date: Sat, 26 Sep 2026 18:06:48 GMT Subject: [PATCH] p5551: fix repeated runs with update-ref --no-deref Message-ID: <20260926180648.60770-1-jon@jonsimons.org> Update p5551-fetch-rescan.sh to pass `--no-deref` when deleting child test refs before each measured `git fetch`. Otherwise, for repeated runs, the second iteration will fail with: fatal: multiple updates for 'refs/remotes/origin/master' (including one via symref 'refs/remotes/origin/HEAD') are not allowed Starting with 3f763ddf28 (fetch: set remote/HEAD if it does not exist, 2024-11-22), `git fetch` instantiates the HEAD symref. The test, introduced in 7893bf1720 (p5551: add a script to test fetch pack-dir rescans, 2017-11-20), predates that.
