Martin Panter added the comment:
I don’t understand what 2.7 has got to do with using subprocess or not. Jumping
through a shell quoting hoop only to pass a command to the shell to be unquoted
seems like double handling. This is how I might rewrite it (untested):
q_cmd = ("rpm", "-q", "--qf", r"%s %s\n" % (...), "--specfile", spec_path)
with subprocess.Popen(q_cmd, stdout=PIPE, universal_newlines=?) as proc:
for line in proc.stdout:
...
if proc.returncode:
raise DistutilsExecError(...)
