From 4c5abf428203524aac7ec094da692e5b89782127 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Sun, 8 May 2005 00:05:18 -0700 Subject: [PATCH] Allow removal of "path" when "path/file" exists. When we used to have "path" as a file or a symlink, but now we have "path/file" (or in general, have "path" as a directory), we would want to remove "path" before adding "path/file". The logic in add_file_to_cache() only runs lstat() and does not detect this case and fails to allow removing it in this case. In the opposite case of having "path/file" in the index and having "path" on the filesystem as a file or a symlink we do allow removal of "path/file", so to be symmetric we should allow it as well, without forcing the user to say --force-remove.
