From 4ae6d4699f4d1df7cd3ffac9dd361c86d62eca42 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Thu, 31 Jan 2013 19:26:21 -0800 Subject: [PATCH] git-am: record full index line in the patch used while rebasing Earlier, a230949 (am --rebasing: get patch body from commit, not from mailbox, 2012-06-26) learned to regenerate patch body from the commit object while rebasing, instead of reading from the rebase-am front-end. While doing so, it used "git diff-tree" but without giving it the "--full-index" option. This does not matter for in-repository objects; during rebasing, any abbreviated object name should uniquely identify them. But we may be rebasing a commit that contains a change to a gitlink, in which case we usually should not have the object (it names a commit in the submodule). A full object name is necessary to later reconstruct a fake ancestor index for them.
