From 9c20a4706767e6003e62f6500ed94ccddcbe322f Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Mon, 21 Nov 2005 21:46:57 -0800 Subject: [PATCH] Teach update-index to read from ls-tree. git-update-index --index-info can almost be usable to read from ls-tree output to update the index (and not the working tree file) to HEAD commit, but not quite. It was designed to read from git-apply --index-info output, and does not want " blob " in ls-tree output. Accept that as well. This lets us update "git-checkout " that used to filter the extra " blob " string out. Noted by Luben.
