#36434 closed Bug

manage.py runserver only respects python -u flag if --noreload is present (-u flag forces streams to be unbuffered) — at Version 1

Description (last modified by Ivan)

From python help:

-u     : force the stdout and stderr streams to be unbuffered;
         this option has no effect on stdin; also PYTHONUNBUFFERED=x

Running manage.py runserver only respects python -u flag if --noreload is present, meanwhile setting the environment variable PYTHONUNBUFFERED=1 works fine.

The solution is likely to make sure subprocesses are called with the very same flag.
