Subject: Minor regression in 2.35 with reflog expire
Date: Thu, 10 Mar 2022 20:08:32 +0100 [thread overview]
Message-ID: <571c0796-66d4-e8c7-c5a5-2e7a28132aa9@kdbg.org> (raw)
Since daf1d8285eeb ("reflog expire: don't use
lookup_commit_reference_gently()", 2021-12-22) we see
$ git reflog expire --all
error: Could not read 0000000000000000000000000000000000000000
that was not there before.
The problem seem to be empty reflog files. I assume they can be created
when reflogs expire completely. I have a handful of them in repository
that was quiet for a long while.
To reproduce:
git init
mkdir -p .git/logs/refs/heads
touch .git/logs/refs/heads/foo
git reflog expire --all
The "scary" aspect of the regression is that it happens as part of git
gc and alarms users, see for example
