From ac0986e302b9a94fd927e8d0a811fe6dc4d4c074 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=86var=20Arnfj=C3=B6r=C3=B0=20Bjarmason?= Date: Sat, 16 Oct 2021 11:39:17 +0200 Subject: [PATCH] refs API: make files_copy_or_rename_ref() et al not set errno MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit None of the callers of rename_ref() and copy_ref() care about errno, and as seen in the context here we already emit our own non-errno using error() in the case where we'd use it. So let's have it explicitly ignore errno, and do the same in commit_ref_update(), which is only used within other code in files_copy_or_rename_ref() itself which doesn't care about errno either. It might actually be sensible to have the callers use errno if the failure was filesystem-specific, and with the upcoming reftable backend we don't want to rely on that sort of thing, so let's keep ignoring that for now.
