Twisted is great, but how cant i emulate sleep behaviour in syested. I know that exists callLater, but how to use it in yield scenario, like here:

@inlineCallbacks def work(self): l_attempts = 0;

while l_attemps < 3: try: resp = yield <some twisted call> break;

except: yield sleep(3); l_attempts +=1

else: log.err("cant communicate");

Here i make 3 attempts to connect busy service, with pause 3 seconds between attempts. How cant i implement this in twisted

Perhaps you want ReconnectingClientFactory ? Set maxRetries to 3. See twisted.internet.protocols.ReconnectingClientFactory. -- Regards, Stephen Thorne Development Engineer Netbox Blue

Hi Ruslan, Try this to drop in to your code, as in: sleep(3) def sleep(secs): d = defer.Deferred() reactor.callLater(secs, d.callback, None) return d Cheers, Luke On Sun, 2010-09-19 at 16:04 +0400, ruslan usifov wrote:
