From: Cameron Dale Date: Thu, 10 Jan 2008 20:45:04 +0000 (-0800) Subject: Use function for sending krpc responses, and add spew parameter. X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=e6beef78406c3093fc4eb98c4293b9257b44aa61;p=quix0rs-apt-p2p.git Use function for sending krpc responses, and add spew parameter. Sending a response in the krpc module now calls a function. There is a new 'SPEW' config variable that causes the krpc module to spew out all sent and received packet data (previously called noisy). Also changed all the tests to use failUnlessEqual instead of assertEqual, and all assert() commands no longer use brackets. Updated some of the downloading tests for the new file sizes on camrdale.org (need a better solution here). --- diff --git a/apt-dht.py b/apt-dht.py index a532527..3cc5d94 100644 --- a/apt-dht.py +++ b/apt-dht.py @@ -57,7 +57,7 @@ application = service.Application("apt-dht", uid, gid) log.msg('Starting DHT') DHT = __import__(config.get('DEFAULT', 'DHT')+'.DHT', globals(), locals(), ['DHT']) -assert(IDHT.implementedBy(DHT.DHT), "You must provide a DHT implementation that implements the IDHT interface.") +assert IDHT.implementedBy(DHT.DHT), "You must provide a DHT implementation that implements the IDHT interface." myDHT = DHT.DHT() myDHT.loadConfig(config, config.get('DEFAULT', 'DHT')) myDHT.join() diff --git a/apt_dht/HTTPDownloader.py b/apt_dht/HTTPDownloader.py index 91ce7c1..c906c0e 100644 --- a/apt_dht/HTTPDownloader.py +++ b/apt_dht/HTTPDownloader.py @@ -36,7 +36,7 @@ class HTTPClientManager(ClientFactory): self.connector = None def connect(self): -
