This is quite interesting. I've been looking for a way to build a site scraper (something analogous to an aggregator but more site-specific) that could eventually become asynchronous, and this looks a lot easier than Twisted. It's like a cron scheduler for interruptible functions, which fits my brain. The WSGI interface and backdoor (interactive) interface could also serve as a UI for accessing the data down the road, although I'm not sure that needs to be in the same process, or whether to use a web or GUI interface or both. One thing that's unclear is what "executed within the main loop's coroutine" means (call_after() function). That means it's inserting Python statements into the other routine, or using its locals and globals? The example shows a delayed timeout example, where the exception is delivered to the current coroutine (the caller) rather than to the main loop's coroutine. Or is everything "executed in the main loop's coroutine"? > They comment the NginxNgxWSGIModule and his use. Its interesting too the > path to python sockets.

There are engine args 'creator' and 'pool' which provide some support for external connection factories and customized pools. -- Mike Orr <[EMAIL PROTECTED]> --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "pylons-discuss" group.
