Hello!
Is there any way I can make twisted stop accepting connections for a short period of time and then start accepting connections? Something like reactor.pause()?
More precisely, what I want to do is to reread my server configuration on SIGHUP (or some other external event). If possible I would like to do this without locking a mutex when accessing (reading or modifying) the configuration info. I figure that reconfiguring the server will be a rare event. So if there is some way that I can:
- Block incoming requests. Preferable keeping them in the connection queue.
- Wait for all running requests to complete.
- Reread the server configuration.
- Unblock incoming requests.
What do you think? Is there some simple twisted-way to do this?
It's really necesary do that?
1 Your app have a reference to a object whith the loaded config 2 A defered take a reference to these object 3 A reread event change the app config reference to new loaded config object. Old defered no change his reference and end whith old config. 4 New defereds take new config and reference that. 5 When old config object have not references is garbaged collected.
No blocking operation is nedded if you can load 2 configuration objects in memory (the old one for connections in progress and the new one).
Excuse my poor english.

Javi
If this has been covered in the past, please point me in that direction. :-)
