From 2cfe66a8ee57fb3da18c262db8e6df95e263510b Mon Sep 17 00:00:00 2001 From: Jacob Keller Date: Thu, 13 Apr 2017 10:12:24 -0700 Subject: [PATCH] ls-files: fix path used when recursing into submodules Don't assume that the current working directory is the root of the repository. Correctly generate the path for the recursing child processes by building it from the work_tree() root instead. Otherwise if we run ls-files using --git-dir or --work-tree it will not work correctly as it attempts to change directory into a potentially invalid location. Best case, it doesn't exist and we produce an error. Worst case we cd into the wrong location and unknown behavior occurs. Add a new test which highlights this possibility.
