From 81c3ce3cdce8dffb913243f5b2cc09d9fb966e6c Mon Sep 17 00:00:00 2001 From: Stefan Beller Date: Sun, 10 Aug 2014 23:33:26 +0200 Subject: [PATCH] prepare_revision_walk(): check for return value in all places Even the documentation tells us: You should check if it returns any error (non-zero return code) and if it does not, you can start using get_revision() to do the iteration. In preparation for this commit, I grepped all occurrences of prepare_revision_walk and added error messages, when there were none.
