I was testing accessing url "http://newsrss.bbc.co.uk/rss/newsonline_uk_edition/front_page/rss.xml" using getPage() which was working fine until I deliberately changed the url to "http://newsrss.bbc.co.uk/rss/newsonline_uk_edition/front_page/rssZZ.xml" to test error handling. Instead of calling my errback, it gave: Traceback (most recent call last): File "/usr/local/lib/python2.4/site-packages/twisted/python/log.py", line 53, in callWithLogger return callWithContext({"system": lp}, func, *args, **kw) File "/usr/local/lib/python2.4/site-packages/twisted/python/log.py", line 38, in callWithContext return context.call({ILogContext: newCtx}, func, *args, **kw) File "/usr/local/lib/python2.4/site-packages/twisted/python/context.py", line 59, in callWithContext return self.currentContext().callWithContext(ctx, func, *args, **kw) File "/usr/local/lib/python2.4/site-packages/twisted/python/context.py", line 37, in callWithContext return func(*args,**kw) --- <exception caught here> --- File "/usr/local/lib/python2.4/site-packages/twisted/internet/selectreactor.py", line 139, in _doReadOrWrite why = getattr(selectable, method)() File "/usr/local/lib/python2.4/site-packages/twisted/internet/tcp.py", line 349, in doRead return self.protocol.dataReceived(data) File "/usr/local/lib/python2.4/site-packages/twisted/protocols/basic.py", line 232, in dataReceived why = self.lineReceived(line) File "/usr/local/lib/python2.4/site-packages/twisted/web/http.py", line 341, in lineReceived key, val = line.split(':', 1) exceptions.ValueError: need more than 1 value to unpack ------------------- Code: from twisted.internet import reactor from twisted.web.client import getPage def handleCallback(response): print 'response: %s' % response reactor.stop() def handleErrback(failure): print 'error: %s' % failure.getErrorMessage() reactor.stop() url = "http://newsrss.bbc.co.uk/rss/newsonline_uk_edition/front_page/rssZZ.xml" deferred = getPage(url) deferred.addCallbacks(handleCallback, handleErrback) reactor.run() ------------------- Is there a fix for this problem ?
