OK.
Interesting and your analysis sounds right. I am not sure how this could be
handled. A test case with execute.py would be a good start, see the end of the
file.
We could try passing “universal_newlines=True” to the subprocess.Popen()
constructor. This will open stdin/stdout/stderr in text mode, using the current
locale setting. Python 3.6+ allows specifying the encoding in the constructor,
if that makes a difference. Another option would be to manually wrap the output
streams in an io.TextIOWrapper, which is essentially what Popen() does when
given any of these arguments.
We need to support python 2.7 but I like what you are suggesting. Any
chance of a patch for execute.py? Anything that helps in this area is
welcome. It is a hot spot for performance as well.
Thanks for looking into this.
Chris
