instead of subbing out to 'rm -rf', you can do:

if os.path.exists(local_dir):
  shutil.rmtree(local_dir)

but either is fine with me.

[navabi, 2015/01/06 19:10:13]

Done.

[cjhopman, 2015/01/06 02:04:04]

check_call throws an exception if the returncode is non-zero, so you don't need
to handle that case for all of these

[navabi, 2015/01/06 19:10:13]

Acknowledged.

[cjhopman, 2015/01/06 02:04:04]

You could use python's zipfile here

something like:

with zipfile.ZipFile(local_zip) as z:
  z.extractall(path=SDK_EXTRAS_PATH)

[navabi, 2015/01/06 19:10:13]

Done.

this if/else can just be:

  subprocess.check_call(...cp...)
return clean_and_extract(arg)

[navabi, 2015/01/06 19:10:13]

Done. (and there is really no point in doing the stat. It's to check if cp is
going to work, but we may as well just try to cp).
