Subject: [PATCH 1/2] setup.c: add enter_work_tree()
Date: Thu,  7 Oct 2010 11:46:52 +0700	[thread overview]
Message-ID: <4cad50cc.0626730a.5616.673d@mx.google.com> (raw)
In-Reply-To: <y>

From: Nguyễn Thái Ngọc Duy <pclouds@gmail.com>

This function, apart from chdir() to worktree topdir, also invalidates
inside_work_tree so is_inside_work_tree() should reflect the new
situation correctly.

This function may be used when cwd is outside worktree and the running
command supports this case.

Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com>
---
 To be used by builtin/grep.c when cwd is outside worktree.
 More explanation in the next patch.

  * set_work_tree() is only ever called if you set GIT_DIR explicitly.
  * The old behaviour (which we retain here) is to set the work tree root
