commit 23f401d5e015ebfb283df1a86e82540c1507083d Author: Isis Lovecruft <isis@torproject.org> Date: Tue Nov 5 06:00:48 2013 +0000 Catch potential KeyErrors on bridge ID lookups in bridgedb.Main. We should catch the KeyError here, as sometimes this loop gets a bridge ID from an extra-info descriptor and tries to lookup the bridge, causing a KeyError on the lookup. * ADD try/except wrapper to catch KeyErrors on looking up bridges by ID in the bridges dict in bridgedb.Main.load(). --- lib/bridgedb/Main.py | 17 +++++++++++------ 1 file changed, 11 insertions(+), 6 deletions(-) diff --git a/lib/bridgedb/Main.py b/lib/bridgedb/Main.py index 5479d6a..29d457b 100644 --- a/lib/bridgedb/Main.py +++ b/lib/bridgedb/Main.py @@ -136,12 +136,17 @@ def load(cfg, splitter, clear=False): f = open(filename, 'r') for transport in Bridges.parseExtraInfoFile(f): ID, method_name, address, port, argdict = transport - if bridges[ID].running: - logging.debug(" Appending transport to running bridge") - bridgePT = Bridges.PluggableTransport( - bridges[ID], method_name, address, port, argdict) - bridges[ID].transports.append(bridgePT) - assert bridges[ID].transports, "We added a transport but it disappeared!" + try: + if bridges[ID].running: + logging.debug(" Appending transport to running bridge") + bridgePT = Bridges.PluggableTransport( + bridges[ID], method_name, address, port, argdict) + bridges[ID].transports.append(bridgePT) + assert bridges[ID].transports, \ + "We added a transport but it disappeared!" + except KeyError as error: + logging.error("Could not find bridge with fingerprint '%s'." + % Bridges.toHex(ID)) logging.debug("Closing extra-info document") f.close() if hasattr(cfg, "COUNTRY_BLOCK_FILE"):
