I'm still not sure that this will properly handle individual push path if the
directory is multiple levels deep. I'm writing a quick test to check.

[jbudorick, 2014/05/20 18:53:53]

Still not sure w.r.t. the above (although leaning toward it not being an issue),
but this doesn't appear to work if the device_path is the intended file name on
the device rather than the intended directory.

[Kibeom Kim (inactive), 2014/05/20 19:06:15]

Oh, I wasn't aware of that device_path can also be a file path. Is it OK to
assume that if host_path is a dir, then device_path is also a dir? (well,
obviously otherwise doesn't make sense)

so like.

if os.path.isdir(host_path):
  self.RunShellCommand('mkdir -p "%s"' % device_path)

[jbudorick, 2014/05/20 19:09:40]

Yeah, that seems fine to me. As you said, it wouldn't really make sense
otherwise.

[Kibeom Kim (inactive), 2014/05/20 19:13:27]

Done.

       # of 60 seconds which isn't sufficient for a lot of users of this method.
