You could use a closure function to do that, like this:
def spider_closed_handler(id):
def wrapped_handler(spider, reason):
self.update_state(id, FINISHED)
if all(val.state==FINISHED for val in self.crawlers.values()):
reactor.stop()
return wrapped_handler
Then:
crawler.signals.connect(spider_closed_handler(id),
signal=signals.spider_closed)
