New description:
We have an integration test where we start two separate Django processes
and the second process makes a POST request to the first process with the
requests library. This testcase broke once we upgraded to Django 1.11,
while it still worked in Django 1.10.
To reproduce the issue:
- Create a simple Django app.
- Install selenium and requests
- Add a testcase like so:
{{{#!python
import time
from django.contrib.staticfiles.testing import StaticLiveServerTestCase
from django.urls import reverse
from selenium import webdriver
class TestExample(StaticLiveServerTestCase):
def test_example(self):
driver = webdriver.Chrome()
driver.get(self.live_server_url + reverse('admin:index'))
# wait "forever"
time.sleep(60 * 60 * 24)
}}}
I.e it just opens the admin page in Chrome, then waits for 24 hours. In a
Python console, type the following:
{{{#!python
import requests
requests.get('http://localhost:47256/admin') # replace 47256 with whatever
port number the LiveServerTestCase picked
}}}
and you will see that the request hangs indefinitely. Interestingly, it
sometimes helps to press refresh in the Chrome window spawned by Selenium.
