Martin Panter added the comment:
Maybe you don’t want to touch the implementation of the “older high-level API”
for fear of subtly breaking something, but for clarification, and perhaps
documentation, would the old functions now be equivalent to this?
def call(***):
# Verify PIPE not in (stdout, stderr) if needed
return run(***).returncode
def check_call(***):
# Verify PIPE not in (stdout, stderr) if needed
run(***, check=True)
def check_output(***):
# Verify stderr != PIPE if needed
return run(***, check=True, stdout=PIPE)
If they are largely equivalent, perhaps simplify the documentation of them in
terms of run(), and move them closer to the run() documentation.
Is it worth making the CalledProcessError exception a subclass of
CompletedProcess? They seem to be basically storing the same information.
