[ooni-probe/master] Really handleAllFailures()
by art＠torproject.org 02 Dec '15

commit 2c9b6e2984df5f5bf18e78981b767e1ad5eed8f5 Author: srvetus <srvetus(a)users.noreply.github.com> Date: Fri Sep 25 00:23:53 2015 +0200 Really handleAllFailures() handleAllFailures() only handles failures which are explicitly named. Maybe it should be renamed or emit a log message when an unknown failure is reraised from `failure.trap()` The known failure list has been converted to a list of tuples as the order of the failure checking is important. Some Failures subclass other failures and so they should be listed from most specific failure to the least specific. --- ooni/errors.py | 69 ++++++++++++++++++++++++++++---------------------------- 1 file changed, 34 insertions(+), 35 deletions(-) diff --git a/ooni/errors.py b/ooni/errors.py index 5751baf..84c0afc 100644 --- a/ooni/errors.py +++ b/ooni/errors.py @@ -20,33 +20,33 @@ from txsocksx.errors import TTLExpired, CommandNotSupported from socket import gaierror -known_failures = { - ConnectionRefusedError: 'connection_refused_error', - ConnectionLost: 'connection_lost_error', - ConnectError: 'connect_error', - CancelledError: 'task_timed_out', - gaierror: 'address_family_not_supported_error', - DNSLookupError: 'dns_lookup_error', - TCPTimedOutError: 'tcp_timed_out_error', - ResponseNeverReceived: 'response_never_received', - DeferTimeoutError: 'deferred_timeout_error', - GenericTimeoutError: 'generic_timeout_error', - SOCKSError: 'socks_error', - MethodsNotAcceptedError: 'socks_methods_not_supported', - AddressNotSupported: 'socks_address_not_supported', - NetworkUnreachable: 'socks_network_unreachable', - ConnectionError: 'socks_connect_error', - ConnectionLostEarly: 'socks_connection_lost_early', - ConnectionNotAllowed: 'socks_connection_not_allowed', - NoAcceptableMethods: 'socks_no_acceptable_methods', - ServerFailure: 'socks_server_failure', - HostUnreachable: 'socks_host_unreachable', - ConnectionRefused: 'socks_connection_refused', - TTLExpired: 'socks_ttl_expired', - CommandNotSupported: 'socks_command_not_supported', - ProcessDone: 'process_done', - ConnectionDone: 'connection_done', -} +known_failures = [ + (ConnectionRefusedError, 'connection_refused_error'), + (ConnectionLost, 'connection_lost_error'), + (CancelledError, 'task_timed_out'), + (gaierror, 'address_family_not_supported_error'), + (DNSLookupError, 'dns_lookup_error'), + (TCPTimedOutError, 'tcp_timed_out_error'), + (ResponseNeverReceived, 'response_never_received'), + (DeferTimeoutError, 'deferred_timeout_error'), + (GenericTimeoutError, 'generic_timeout_error'), + (SOCKSError, 'socks_error'), + (MethodsNotAcceptedError, 'socks_methods_not_supported'), + (AddressNotSupported, 'socks_address_not_supported'), + (NetworkUnreachable, 'socks_network_unreachable'), + (ConnectionError, 'socks_connect_error'), + (ConnectionLostEarly, 'socks_connection_lost_early'), + (ConnectionNotAllowed, 'socks_connection_not_allowed'), + (NoAcceptableMethods, 'socks_no_acceptable_methods'), + (ServerFailure, 'socks_server_failure'), + (HostUnreachable, 'socks_host_unreachable'), + (ConnectionRefused, 'socks_connection_refused'), + (TTLExpired, 'socks_ttl_expired'), + (CommandNotSupported, 'socks_command_not_supported'), + (ProcessDone, 'process_done'), + (ConnectionDone, 'connection_done'), + (ConnectError, 'connect_error'), +] def handleAllFailures(failure): """ @@ -55,9 +55,7 @@ def handleAllFailures(failure): returned by failure.trap().
