From a5a959d9a8481f46f89be437d7b336c70b473d9b Mon Sep 17 00:00:00 2001 From: Elijah Newren Date: Wed, 27 Jun 2018 08:48:03 -0700 Subject: [PATCH 1/3] t3418: add testcase showing problems with rebase -i and strategy options We are not passing the same args to merge strategies when we are doing an --interactive rebase as we do with a --merge rebase. The merge strategy should not need to be aware of which type of rebase is in effect. Add a testcase which checks for the appropriate args.

After splitting, sequencer.c prefixed each "option" with a double dash, so, concatenating all its options would result in: -- --ours -- --renormalize So, when it ended up calling try_merge_strategy(), that in turn would run git merge-$strategy -- --ours -- --renormalize $merge_base -- $head $remote instead of the expected/desired git merge-$strategy --ours --renormalize $merge_base -- $head $remote Remove the extra spaces so that when it goes through split_cmdline() we end up with the desired command line.
