Hi,
I'm having a issue with Django's dev server. I did a "django-admin.py
startproject" then "manage.py startapp home", then added the app in
settings.py and in urls.py. The app only has a index function in
views.py which is mapped to / and just renders a simple html template.
What happens is that sometimes(and this is often) when i load the page
in a broswer (tryed Chrome and Firefox) or refresh it, the page starts
loading but it never finishes. And if i hit the browser's stop button
i get this in the console
Exception happened during processing of request from ('127.0.0.1',
52495)
Traceback (most recent call last):
File "C:\Python26\lib\SocketServer.py", line 283, in
_handle_request_noblock

software in your host machine
----------------------------------------
Any idea what's causing this? As it really cripples my dev time.

The exception you're seeing is just a response to stopping the request in the browser. The real problem is that your view function is hanging. Could you post the source to the view (and the substantial parts of your template)? Very hard to offer suggestions without the right data.

You'll probably want to install the Django debug toolbar (https://github.com/robhudson/django-debug-toolbar) at some point, though it doesn't help much with views that hang or throw exceptions.

Hi,
Your files seem fine, I believe.
Have you found the cause? What version of python and django are you
using? I also have this issue but it is not often enough for me to
worry too much. Killing the server and restarting it solves it for
me..

Hi,
Unfortunately i did not found the case, and i'm getting it pretty
often, about 3 out of 5 times i refresh the page.
If i leave it loading and i don't stop it it stays like that for about
30-40 seconds and then the page loads.
I just don't understand what is causing this.
I've restarted the server like 10 time or more from the first time i
got this and i'm still getting it every time i run it.
My Python version is : ActivePython 2.6.6.17 (ActiveState Software
Inc.) based on
Python 2.6.6 (r266:84292, Nov 24 2010, 09:16:51) [MSC v.1500 32 bit
(Intel)] on
win32
and Django: (1, 2, 3, 'final', 0)
I did a lot of dev on Windows 7 before but i never had this issue. So
my thoughts are that this is either
related to this Django version or Python version.

I'm currently developing on Windows 7 (64-bit) with stock Python 2.6.6 (32-bit) and Django 1.2.3, and having no problems when running the Django development server from the command line.
I'd recommend using the normal Python (http://www.python.org/download/releases/2.6.6/) instead of ActivePython and see if that improves things.

Have you tried using pdb to debug the call as it arrives? You could step through the code, line by line that way to see what is hanging.

I enthusiastically second this. If you're unfamiliar with pdb, check out this slice of awesome:
Incidentally, the Python doc page has just a bit that's not in the tutorial. The only thing that springs to mind is the 'skip' argument, but you might want to skim it. The debugger is a fantastic tool to have in your toolbox.

Just tried latest version of Django 1.2.4 and same issue
I'll try that. Never used pdb before so let's see how things will go.
I'll reply with updates.

Ok, so i used pdb and did a line by line pass, but i didn't get anything.
All data seems to be normal. I even edited socket.py and did a print on data
to see what's going on and everything seems normal.. :( so i'm left with no idea
I guess i'll have to get used with this hangs.

It sounds like it wasn't able to be reproduced with pdb. I think that should be looked into further.

Were you able to solve the problem? I regularly get hangs (around a
minute) as well, using python 2.6.5 from MacPorts and Django 1.2,
usually when using Chrome's incognito mode. Also, I sometimes have to
reload the page multiple times until all the media files load since
there seem to be errors in the requests.
My traceback usually looks like this:
Traceback (most recent call last):

I am now using http://www.newthink.net/2010/12/17/multi-threaded-django-dev-server/
which has solved the problem so far.

Hi,
I don't know much of windows, but couldn't it be some kind of network filtering, parental control or whatever that creates this behavior ?
@daniels: your issue is different. Django dev server only serves one request at a time. It looks like your chrome does several request at the same time.
I'm on osx, with chrome (out of the box) and django dev server and haven't seen an issue yet.
Regards,
Xavier.

The problem is in your packages. You probably tried to solve so other issue and installed some package that you dont need.
I had the same problem, clearing unused packages solved the problem

open your task manager and stop python process running it and then again runserver
