+Subject: [PATCH 2/2] dbc2val: usability improvements
Changes:
- Tweaked default configuration file search path to better match
Linux FHS and kuksa-val-server. First look for a config.ini in
/etc/kuksa-dbc-feeder, then /etc/dbc_feeder.ini.
-- Added a command-line option to specify configuration file, this
- should allow running two instances against different interfaces.
-- Added verbosity command-line option and made several messages
- verbose mode only to avoid log spamming.
-- Added '-u' option to python invocation to disable output buffering.
- The intent is to make logging immediate, otherwise errors may not
- get logged for some time (or at all).
- 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.
+- Fixed shutdown behavior with some tweaks to actually stop the
+ reader and KUKSA.val client library threads. This makes the
+ script actually exit on SIGTERM as opposed to hanging.
Upstream-Status: pending
