From beb5af43a6114b551f14bc13f1beecfe8de930d9 Mon Sep 17 00:00:00 2001 From: Adam Simpkins Date: Tue, 18 Aug 2009 19:34:33 -0700 Subject: graph API: fix bug in graph_is_interesting() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Previously, graph_is_interesting() did not behave quite the same way as the code in get_revision(). As a result, it would sometimes think commits were uninteresting, even though get_revision() would return them. This resulted in incorrect lines in the graph output. This change creates a get_commit_action() function, which graph_is_interesting() and simplify_commit() both now use to determine if a commit will be shown. It is identical to the old simplify_commit() behavior, except that it never calls rewrite_parents(). This problem was reported by Santi Béjar. The following command would exhibit the problem before, but now works correctly: git log --graph --simplify-by-decoration --oneline v1.6.3.3 Previously git graph did not display the output for this command correctly between f29ac4f and 66996ec, among other places.
