Subject: [PATCH v4 3/4] refs/files-backend: correct return value in lock_ref_for_update
Date: Sat, 9 Sep 2017 08:57:17 +0200 [thread overview]
Message-ID: <3b2adfcb53d1564f7e794ec5cfbbb93c37c9f3a5.1504939825.git.martin.agren@gmail.com> (raw)
In-Reply-To: <cover.1504939825.git.martin.agren@gmail.com>
In one code path we return a literal -1 and not a symbolic constant. The
value -1 would be interpreted as TRANSACTION_NAME_CONFLICT, which is
wrong. Use TRANSACTION_GENERIC_ERROR instead (that is the only other
return value we have to choose from).
