I did the following:

• install firepython and jsonpickle
• add firepython.middleware.FirePythonDjango and firepython.middleware.FirePythonWSGI to MIDDLEWARE_CLASSES.

My setup is the following:

• django 1.1 - manage.py run as a thread
• lighttpd with fcgi enabled

Everything works fine without FirePython but I really want to use that great debug tool. When I add the 2 classes, all http request passed to manage.py timeout.

manage.py is up and running but seems to not handle any requests anymore.

Any help would be appreciated.

On trunk, the WSGI middleware fails for output_wrapper

Changing to:
output = list(app_iter)
from:
output = outer_wrapper(app_iter)
works

Since Firelogger 1.0 is on the way:
http://getsatisfaction.com/binaryage/topics/is_there_planned_upgrade_to_make_firelogger_compatible_with_firefox_4

FireLogger (client) has version "1.0", but FirePython (server) is version "0.9". Check http://firelogger.binaryage.com for latest version.

Prepare tutorial page, so people can test-drive the extension.

Also explain difference between:
x = { ... }
logging.debug(x)
logging.debug("%s" % x)
logging.debug("%s", x)

Using 0.7 on the client and 0.5 on the server

So for example if I log a URL that has a %20 in it:

http://myurl.com/someurl?key=my%20value

It shows up like this:

http://myurl.com/someurl?key=myundefined20value

Hi, it looks like your plugin breaks with firebug 1.4: https://addons.mozilla.org/it/firefox/addon/11090

FirePython add 'X-FirePython/0.1' to the user-agent string.

Some websites (eg. wordreference.com) prevent bot access blocking user-agent with 'Python' in the useragent string.

Right now if the page does a submit, the logger pane gets cleared. It would be useful to have history available (for server side generated redirects mainly).

I’m using it with pylons and emacs, and it totally kicks ass! Thanks for the awesome extension.
