[Twisted-Python] Use of twisted as web app core
by Ben.Young＠risk.sungard.com Feb. 11, 2005

Feb. 11, 2005

Hi there, I am trying to evaluate the possible use of twisted as the event framework around which my web app will hang. I would like my app to be run under mod_fastcgi as I like the process control this brings as well as the automatic load balancing across processes. I would also like to use the spread communication toolkit (not twisted spread) to act as a control console to be able to send messages such as "flush cache" to all active processes, even if they are on multiple machines. … [View More]

[Twisted-Python] best way to turn on SO_KEEPALIVE option on all sockets
by Alec Matusis Feb. 11, 2005

Feb. 11, 2005

Hello, I was wondering what is the best way to turn on KEEPALIVE option on all sockets opened by my twisted server. I have inserted s.setsockopt(socket.SOL_SOCKET,socket.SO_KEEPALIVE,1) line into twisted/internet/base.py class BasePort(abstract.FileDescriptor): """Basic implementation of a ListeningPort.""" addressFamily = None socketType = None def createInternetSocket(self): s = socket.socket(self.addressFamily, self.socketType) s.setblocking(0) ++ s.… [View More]

Might be better to add this sort of stuff to web2, since that's where the active development is happening (especially since that probably has rewritten range header support).

[Twisted-Python] Suggestion for Deferred docs
by snacktime Feb. 10, 2005

Feb. 10, 2005

I know this would have helped me, maybe it would others. In the documentation on Deferred's in the howto section, the examples that show a blocking operation and then a non blocking operation do not show what happened to the blocking code, it just conveniently disappears. For someone new to async programming it might help to give an example that shows the blocking code being called via deferToThread. In other words show how you would handle blocking code. It doesn't matter if there are 10 … [View More]

[Twisted-Python] async code structure question
by snacktime Feb. 10, 2005

Feb. 10, 2005

Since I'm new to having to structure everything for async programming, I thought I would see if my idea on how to restructure my code makes sense. Say I have a class with several functions that are called in order. Each function relies on the results of the previous function in order to proceed. To write this asynchronously, do I chain them together so that each function is called as a deferred, with the callback pointing to the next function and so forth down the list? Chris

[Twisted-Python] wxPython
by Neal Nelson Feb. 10, 2005

Feb. 10, 2005

I can't seem to get wxPython to work with Twisted 1.3. I started developing a system some time ago but I've only just got back to it and the user interface no longer works, which is a bit of a problem. Should wx work or is this broken in Twisted?

[Twisted-Python] twisted-web alive?
by snacktime Feb. 9, 2005

Feb. 9, 2005

It could just be gmail, but given that I've sent two messages to twisted-web and neither showed up in my mailbox (and no replies either) I'm wondering if something is wrong with the twisted-web list? The messages do show up when I browse the archives. Chris

[Twisted-Python] twisted.enterprise.adbapi appropriate?
by snacktime Feb. 9, 2005

Feb. 9, 2005

Say I have a client/server application where the sequence basically goes like this: 1. client connects 2. server queries database 3. server uses results of query to do blocking operation (http POST to another server) 4. server inserts some data into database (1-3 inserts) 5. server sends reply to client Right now 2-4 is all in a single method that I just call with deferToThread, and the callback takes care of 5. I'm trying to understand what advantages I would get from doing this: - … [View More]
