From 60cc3c4072259609aefbdbc762d1f72bcbd97783 Mon Sep 17 00:00:00 2001 From: Michael Haggerty Date: Fri, 12 Dec 2014 09:56:47 +0100 Subject: Extract function should_expire_reflog_ent() Extract from expire_reflog_ent() a function that is solely responsible for deciding whether a reflog entry should be expired. By separating this "business logic" from the mechanics of actually expiring entries, we are working towards the goal of encapsulating reflog expiry within the refs API, with policy decided by a callback function passed to it by its caller.
