From f432c33f27898070718dd568feb104fc1870ca15 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 15 Jun 2016 14:33:52 +0900 Subject: [PATCH] tools: moveconfig: simplify source tree switching The subprocess.Popen() does not change the child process's working directory if cwd=None is given. Let's exploit this fact to refactor the source directory handling. We no longer have to pass "-C " to the sub-process because self.current_src_dir tracks the source tree against which we want to run defconfig/autoconf. The flag self.use_git_ref is not necessary either because we can know the current state by checking whether the self.current_src_dir is a valid string or None.
