From 185c975faaa790a98a4e00f124461473283500d6 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Fri, 16 Feb 2007 22:43:48 -0800 Subject: Do not take mode bits from index after type change. When we do not trust executable bit from lstat(2), we copied existing ce_mode bits without checking if the filesystem object is a regular file (which is the only thing we apply the "trust executable bit" business) nor if the blob in the index is a regular file (otherwise, we should do the same as registering a new regular file, which is to default non-executable). Noticed by Johannes Sixt.
