It's a replacement of standard python socket module. What make it
different is that this module only blocks a tasklet, not an entire
Python thread.
With this module and stackless python, theoretic

Someone turn off the server by cutting power of the server.
When the machine is power on, I found my twisted application could not start
and emit the following error.
Another twistd server is running, PID 3398
This could either be a previously started instance of your application or a

If you Google "sqlalchemy twisted", you can see my post is on the top:

I've been busy for a long time so I didn't considered this question

When my server reboot after an unexpected power cut,
supervisord tried to start a twisted app after an unexpected power cut,
but it fails because "Another twistd server is running, PID 4607"
4607 is the PID of the twisted app before power cut.
After I stopped and restart supervisord, everything is
Hi all,
I am writing a network application based on twisted and following the
"finger service" tutorial in twisted document.
I wrote multiple protocols classes and a single service class.
This allows client to choose the most suitable protocol to access services.
My problem is : the service class
Hi,
I've read some mails in this list that recommend use sqlalchemy in separate

But if u use multiprocessing which provides only synchronous API, doesn't
you have to use deferToThread also?
Another way would be using "twisted.internet.protocol.ProcessProtocol",
which use pipes. But ca

This code would create a new session on each request and close it
immediately.
Hope this trick could save me!

Hi, all
I am using sqlalchemy in twisted in my project in the way below.
Defer any database operation so the twisted's main thread won't be
blocked.
And I use scoped_session, so that sessions won't have to be created
again and again.

Hi,
Thanks for this insightful comments on Sqlalchmy and Twisted.
I hope I had read your mail before I start my current project.
At that time, I simply thought using deferToThread would solve
everything since the twisted.enterprise.adbapi simply use
threads.deferToThreadPool
to make database in
Hi all,
First, I am sorry because it's not a question related to twisted.
But since twisted is a networking programming framework, you might be
interested.
Some of my colleagues have a view that a net work server should be split to
small parts with different functions,
