From 45c45e300bcbe493a39533bb04f6bd548e8a3f19 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Tue, 19 Apr 2011 12:18:20 -0700 Subject: [PATCH] git add: start preparing for "git add ..." to default to "-A" When "git add subdir/" is run without "-u" or "-A" option, e.g. $ edit subdir/x $ create subdir/y $ rm subdir/z $ git add subdir/ the command does not notice removal of paths (e.g. subdir/z) from the working tree. This sometimes confuses new people, as arguably "git add" is told to record the current state of "subdir/" as a whole, not the current state of the paths that exist in the working tree that matches that pathspec (the latter by definition excludes the state of "subdir/z" because it does not exist in the working tree). Plan to eventually make "git add" pretend as if "-A" is given when there is a pathspec on the command line. When resolving a conflict to remove a path, the current code tells you to "git rm $path", but with such a change, you will be able to say "git add $path" (of course you can do "git add -A $path" today). That means that we can simplify the advice messages given by "git status". That all will be in Git 2.0 or later, if we are going to do so. For that transition to work, people need to learn either to say "git add --no-all subdir/" when they want to ignore the removed paths like "subdir/z", or to say "git add -A subdir/" when they want to take the state of the directory as a whole. "git add" without any argument will continue to be a no-op.
