Django not thread-safe?

[Michael Radziej]

Hi,

Jacob states in Ticket #3357 [1] that Django were far from being
thread-safe. But on the other side, Django is able to run as threaded
fastcgi-server (at least with the right backend module version ...)
Isn't this a contradiction?

i think this part is the one where we have to be more exact.

does that mean that : "it is guaranteed to work with a threaded
fastcgi-server"? or more like "i have been using it with a threaded
fastcgi-server, and had no problems for 2 months" ?

This is strange... Known thread-safety bugs (with db backends mostly)
were fixed long ago, even before magic-removal. I used to run Django
under Apache with worker-mpm without problems.

Jacob could you elaborate?

This patch being:

* good for local testing that more closely resembles a real hosting
environment (eg: with AJAX testing)
* for the development server only
* and disabled by default

you'd think it would be an easy inclusion. I'd like to know more too.

Hi,

just for your information, I've reopened the ticket, asking Jacob for
details about Django being not thread-safe.
