Subject: [PATCH v2 5/7] fetch: refactor fetch refs to be more extendable
Date: Tue, 24 Aug 2021 12:37:13 +0200 [thread overview]
Message-ID: <56a9158ac331f9911a4347d7d4afc2bbd2cf4d33.1629800774.git.ps@pks.im> (raw)
In-Reply-To: <cover.1629800774.git.ps@pks.im>
[-- Attachment #1: Type: text/plain, Size: 1537 bytes --]
Refactor `fetch_refs()` code to make it more extendable by explicitly
handling error cases. The refactored code should behave the same.
