From e6f637122ecd60c59df27b8188b6ddac39ac0063 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Carlos=20Mart=C3=ADn=20Nieto?= Date: Thu, 27 Feb 2014 10:00:10 +0100 Subject: fetch: handle overlaping refspecs on --prune MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We need to consider that a remote-tracking branch may match more than one rhs of a fetch refspec. In such a case, it is not enough to stop at the first match but look at all of the matches in order to determine whether a head is stale. To this goal, introduce a variant of query_refspecs which returns all of the matching refspecs and loop over those answers to check for staleness.
