Revision 20c3fe762105a29150fd21e3e0a340bca7890848 authored by Paul Tan on 06 June 2015, 11:46:10 UTC, committed by Junio C Hamano on 08 June 2015, 20:09:20 UTC
Even when a merge conflict occurs with am --3way, the index will be modified with the results of any successfully merged files. These changes to the index will not be reverted with a "git read-tree --reset -u HEAD ORIG_HEAD", as git read-tree will not be aware of how the current index differs from HEAD or ORIG_HEAD. To fix this, we first reset any conflicting entries in the index. The resulting index will contain the results of successfully merged files introduced by the failed merge. We write this index to a tree, and then use git read-tree to fast-forward this "index tree" back to ORIG_HEAD, thus undoing all the changes from the failed merge. When we are on an unborn branch, HEAD and ORIG_HEAD will not point to valid trees. In this case, use an empty tree.
