From d809fb17b00f912112090294ff0257c8a87af56e Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Tue, 1 Jan 2013 16:51:03 +1100 Subject: [PATCH] gitk: Fix display of branch names on some commits Sometimes the code that divides commits up into arcs creates two successive arcs, but the commit between them (the commit at the end of the first arc and the beginning of the second arc) has only one parent and one child. If that commit is also the head of one or more branches, those branches get omitted from the "Branches" field in the commit display. The omission occurs because the commit gets erroneously identified as a commit which is part-way along an arc in [descheads]. This fixes it by changing the test to look at the arcouts array, which only contains elements for the commits at the start or end of an arc.
