As Twisted points out not to be thread-safe, why would it be in WSGI?
Due to the sensibility of the project I cannot afford things to go wrong
because of not synchronized threads or other pitfalls, so I actually
decided
to to the asynchronous way, and this bites with WSGI.

Hi all,
Before I start digging in the Twisted code, I'd just like to bump
this off you in case the solution is obvious...
I have a lot of clients having permanent connections to my TCP
server. These clients are devices that will buffer data if it
In your Protocol, I would implement a specific Error that might be returned
by the server in such burst situations.
The clients should interpret that error in a way that lets them reconnect to
the server after a randomly chosen interval.
This way you immediately eliminate the burst without running
Hi Fabian,
Unfortunately I don't have control over the protocol itself as the
devices are made by different manufacturers. However, your email
did highlight the issue that devices will in very quick succession
try to re-establish connections potentially ca
Don,
If you can't solve the problem proactively by adapting the clients,
You probably need to deal with it on the server side. The common technique
here
Is to use load balancers.
For a software solution, you might want to take a look at
http://sourceforge.net/projects/pythondirector/ .
However,
Thank you Fabian,
I'll take a look at Python Director.

Don

Great, glad to hear it. Let us know how it goes!___

For this websocket cms project im working on, i also run django in a wsgi
container. I wonder if im using it the right way? (

Hey Jeroen,
As I learned so far, using WSGI to combine Django and Twisted isn't a bad
thing in general.
It's just that you need to align your code and 'mental model' to develop
multi-threaded (WSGI) or asynchronous (if that makes any difference to you
at all).
In my special case, I develop a netw
Thanks, it would be nice to see some more examples of django usage with
twisted. I've searched the web a while ago, but could only find a few
examples. Especially the
part about multi-threading/async would be nice to read something
about(doesn't make much sense to me yet). All i know is that i used
That's probably the best Twisted Intro available in the net:
http://krondo.com/?page_id=1327
The first chapter explains the differences between sync/async/threaded.

hello:
I'm making a program that captures a GPS data from a ip port, it
I have an infinite loop to stay to listen, to finish out a

The idea is to put a reactor that allows me to use the variable "list"
without

Wait. You are capturing GPS data from an IP port. Is that TCP? What format
is the data in? GPS?
I have worked on twisted.positioning, a library for doing GPS data with
Twisted, but this ticket is still in review.
