Versatile utility function to run external processes

Features

  • runs an external process and waits for it to finish
  • does not deadlock, no matter the process stdout/stderr output behaviour
  • returns the exit code, stdout, stderr (separately, both as bytestrings), as a subprocess.CompletedProcess object
  • process can run in a custom environment, either as a modification of the current environment or in a new environment from scratch
  • stdin can be fed to the process
  • stdout and stderr is printed by default, can be disabled
  • stdout and stderr can be passed to any arbitrary function for live processing (separately, both as unicode strings)
  • optionally enforces a time limit on the process, raising a subprocess.TimeoutExpired exception if it is exceeded.
