From 0a06892ddde5bc3a82a4fe2963e3ea294252ffdd Mon Sep 17 00:00:00 2001 From: Patrick Steinhardt Date: Thu, 14 Dec 2023 14:37:13 +0100 Subject: bisect: consistently write BISECT_EXPECTED_REV via the refdb We're inconsistently writing BISECT_EXPECTED_REV both via the filesystem and via the refdb, which violates the newly established rules for how special refs must be treated. This works alright in practice with the reffiles reference backend, but will cause bugs once we gain additional backends. Fix this issue and consistently write BISECT_EXPECTED_REV via the refdb so that it is no longer a special ref.
