From a68cca9953cf2e9ef64f355455164025bae0b188 Mon Sep 17 00:00:00 2001 From: Thomas Bachem Date: Thu, 1 Oct 2026 08:24:16 +0000 Subject: [PATCH] t5520: don't expire reflogs where it matters "git merge" saves any uncommitted changes with "git stash" before it tries a merge strategy. When the strategy does not handle the merge, it restores them with "git stash apply --index". If some of the changes are staged, that runs "git reset", which writes an entry to the reflog of HEAD. The tests that pull with autostash disabled run eight such merges, each with a new file staged. An upcoming change makes "git stash apply --index" merge the index in-core, so it no longer runs "git reset" and those entries go away. Another makes the default "merge" backend of "git rebase" run auto maintenance when it finishes. Together, they change when auto maintenance expires the reflogs. This means that unfortunately the reflogs are expired at the end of "git pull --rebase" in the "--rebase with rebased upstream" test. The "git pull --rebase -f" in the next test looks for the fork point in the reflog of refs/remotes/me/copy, but as the test suite dates every reflog entry to 2005, the expiry has emptied that reflog. Pull then finds no fork point, so the rebase also replays copy-orig, the commit "copy" was rewound from, and it conflicts. Disable reflog expiration in this script, as ea7d894f44 (t34xx: don't expire reflogs where it matters, 2026-02-24) did for the rebase tests, so that the test no longer depends on where the expiry falls.
