First look for a config.ini or dbc_feeder.ini in + /etc/kuksa-can-provider, then fall back to /etc/dbc_feeder.ini + before using trying other possible paths. +- Add catching of exceptions around CAN device opening so that the + script can exit cleanly with an error message if the device is + not available. +- Tweaked DBC default value file command line argument parsing so + that it does not attempt to fallback to "dbc_default_values.json" + in the current working directory. That likely works for upstream + test scenarios, but prevents running on a target. + +Upstream-Status: pending + +Signed-off-by: Scott Murray <scott.murray@konsulko.com> +--- + dbcfeeder.py | 19 +++++++++++++++---- + 1 file changed, 15 insertions(+), 4 deletions(-) + +diff --git a/dbcfeeder.py b/dbcfeeder.py +index a1ef174..c252503 100755 +--- a/dbcfeeder.py ++++ b/dbcfeeder.py +@@ -144,7 +144,11 @@ class Feeder: + whitelisted_frame_ids.append(filter.can_id) # type: ignore + elm2canbridge.elm2canbridge(canport, self._elmcan_config, whitelisted_frame_ids) + +- self._reader.start() ++ try: ++ self._reader.start() ++ except: ++ log.error("Could not open %s, exiting", canport) ++ sys.exit(-1) + + receiver = threading.Thread(target=self._run_receiver) + receiver.start() +@@ -165,7 +169,12 @@ class Feeder: + # For now creating another bus + # Maybe support different buses for downstream/upstream in the future + +- self._canclient = CANClient(interface="socketcan", channel=canport, can_fd=can_fd) ++ self._canclient = None ++ try: ++ self._canclient = CANClient(interface="socketcan", channel=canport, can_fd=can_fd) ++ except: ++ log.error("Could not open %s, exiting", canport) ++ sys.exit(-1) + + transmitter = threading.Thread(target=self._run_transmitter) + transmitter.start() +@@ -335,8 +344,10 @@ def _parse_config(filename: str) -> configparser.ConfigParser: + configfile = filename + else: + config_candidates = [ +- "/config/dbc_feeder.ini", ++ "/etc/kuksa-can-provider/config.ini", ++ "/etc/kuksa-can-provider/dbc_feeder.ini", + "/etc/dbc_feeder.ini", ++ "/config/dbc_feeder.ini", + "config/dbc_feeder.ini", + ] + for candidate in config_candidates: +@@ -534,7 +545,7 @@ def main(argv): + elif os.environ.get("DBC_DEFAULT_FILE"): + dbc_default = os.environ.get("DBC_DEFAULT_FILE") + else: +- dbc_default = config.get(CONFIG_SECTION_CAN, CONFIG_OPTION_DBC_DEFAULT_FILE, fallback="dbc_default_values.json") ++ dbc_default = config.get(CONFIG_SECTION_CAN, CONFIG_OPTION_DBC_DEFAULT_FILE, fallback=None) + + if args.mapping: + mappingfile = args.mapping +-- +2.44.0 + |
