Hi
If I want to trap a certain type of exception in a deferred call, how do I
specify it? For example, I see a failure like this:
[HTTP11ClientProtocol (TLSMemoryBIOProtocol),client]
[<twisted.python.failure.Failure <class 'OpenSSL.SSL.Error'>>]
[HTTP11ClientProtocol (TLSMemoryBIOProtocol),client] Traceback
(most recent call last):
[HTTP11ClientProtocol (TLSMemoryBIOProtocol),client] Failure:
twisted.web._newclient.ResponseNeverReceived: [<twisted.python.
failure.Failure <class 'OpenSSL.SSL.Error'>>]
I want to trap all such failures. I tried
`failure.trap(twisted.web._newclient.ResponseNeverReceived)` but looks
like that did not work. My deferred callback looks like this:

like that did not work. My deferred callback looks like this:
from twisted.internet.error import TimeoutError
from twisted.web._newclient import ResponseNeverReceived
def log_ignore_network_errors(failure):
print failure.getErrorMessage()
failure.printTraceback()
failure.trap(TimeoutError, ResponseNeverReceived)
Apparently this does not catch all such errors. What am I doing wrong here?
