Django/CherryPy problem with POST data

[Mark Sundstrom]

Changeset [14394] causes a hang when reading POST data running Django trunk behind CherryPy 3.1.2 and Python 2.7.

See this thread on Django Developers:

Steps to reproduce Ticket #14594

I used a virtualenv running Python 2.7, but I don't think the Python version matters

# Install or make sure you are using Django trunk >= 14394
pip install CherryPy # 3.1.2
django-admin.py startproject newbug
cd newbug
python manage.py runserver # verify on port 8000 that "It works!"
# Edit urls.py to enable the admin
# Edit settings.py to enable the admin
# Edit settings.py to create a database.
# I used sqlite3 and specified a path
python manage.py syncdb # setup the database and create a superuser
# Verify that you can login, using the development server and your new superuser at
# localhost:8000/admin/
# Log out, stop the development server
python manage.py shell

import cherrypy
from django.core.handlers.wsgi import WSGIHandler
cherrypy.tree.graft( WSGIHandler(), script_name="")
cherrypy.quickstart() # this will start the CherryPy server on 8080

# The admin media will not be served, but this doesn't matter
# Go to localhost:8080/admin/
# Try to login with your superuser, or just click the login button with blank input
# Hangs

(In [14435]) Fixed #14594 -- Corrected a problem introduced by r14394 whereby reading POST data when running a WSGI server under CherryPy would hang. Thanks to Mark Sundstrom for the report.

The fix in [14435] is exactly backwards -- content_length should be passed to read() when available, not the other way around.

[Mark Sundstrom]

Patch to reverse the use of content_length applied in [14435]

(In [14436]) Fixed #14594 -- Corrected r14435, which got the logic completely bass ackwards. Thanks to Mark Sundstrom for keeping me honest :-)

Oops - sorry about that. I had the code right in my editor during testing; I just hit undo a few too many times removing some debug before I committed (Honest! I did! :-)
