Revision aa94e60eada5f44e43ecc0684057cc464ba325c1 authored by Ben Woosley on 19 April 2016, 00:49:52 UTC, committed by Ben Woosley on 20 April 2016, 16:57:21 UTC
Absent this fix, attempts to rebase an orphan branch with --strategy recursive will fail with: $ git rebase ORPHAN_TARGET_BASE -s recursive First, rewinding head to replay your work on top of it... fatal: Could not parse object 'ORPHAN_ROOT_SHA^' Unknown exit code (128) from command: git-merge-recursive ORPHAN_ROOT_SHA^ -- HEAD ORPHAN_ROOT_SHA To fix, this will only include the rebase root's parent as a base if it exists, so that in cases of rebasing an orphan branch, it is a simple two-way merge. Note the default rebase behavior does not fail: $ git rebase ORPHAN_TARGET_BASE First, rewinding head to replay your work on top of it... Applying: ORPHAN_ROOT_COMMIT_MSG Using index info to reconstruct a base tree... Signed-off-by: Ben Woosley <ben.woosley@gmail.com>
