Log when use APP_FILE about s2i-python-container HOT 6 CLOSED

I'm not 100% sure I understand your problem. Could you please provide a simple reproducer script and steps to reproduce? Also, which version of Python?

from s2i-python-container.

We did more tests and isolate the problem. When we isolate the code, the problem doesn't happen.
My developer team will investigate the code now.

Apologies for the inconvenience.

Resolved set environment variable:

PYTHONUNBUFFERED=true

Hi, could you please elaborate? Is this something that could happen to
ither people? Is it something preventable by us? What does the mentioned
environment variable do?

Hello @mnagy ,

Set PYTHONUNBUFFERED works for me, but i don't know if this is good practice. In the python manual page don't show many information about this parameter:
https://docs.python.org/3/using/cmdline.html#envvar-PYTHONUNBUFFERED

Steps to reproduce:
oc new-app python:3.4 --name=test-log https://github.com/geovanaSouza/python_runner.git -e APP_FILE=python_runner2.py -l app=test-log

In the log don't show any message. When I wait for sometime (about 30 minutes) show the message in the log.

But, when I set PYTHONUNBUFFERED:
oc env dc test-log PYTHONUNBUFFERED=true

Show the message instantly for my app:
---> Running application from Python script (python_runner2.py) ...
App begin
Message loop
Message loop
Message loop
Message loop

I think when I don't set this parameter the message is stored in memory buffer. When the buffer is full, the message's show in the log.
