Hmm, interesting. It might be worth patching Failure and Deferred on your system to see where the other calls to Failure() [i.e. with no args] are coming from. Specifically patch the part of Deferred._runCallbacks that calls Failure() to say which callback triggered it, and patch Failure.__init__ to report when it is called without args too, because there may be some places that don't happen directly in Deferred… The most obvious other point I can see is in twisted.web.xmlrpc.Proxy, which is hard to avoid nicely. I've pushed up an ugly revision to my branch to try suppress that too, but it's pretty nasty (I have to copy a 15 line method just to change 2 lines). I'm not sure that we'd actually be triggering failing XML-RPC calls in this case though, so it may make no difference. It'd be nice to get hard data on where the other Failure() calls are coming from so we know if there's just one or two places we can adjust, or if it's too widespread to fix this way. -Andrew. _______________________________________________ Mailing list: https://launchpad.net/~launchpad-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~launchpad-dev More help : https://help.launchpad.net/ListHelp
