Public bug reported: when using "normal exit 0 SIGTERM" in a job, and if the job is killed with SIGTERM, a warning message will appear in dmesg, like [330159.038611] init: xxxyyyzzz main process (570) killed by TERM signal
If using "normal exit 0 SIGTERM 15" instead, there won't be such warning message when the job is killed with SIGTERM, 15 is the numerical value for SIGTERM, per "man 7 signal" After reading the code, it looks to me that the issue is: 1. when parsing "normal exit 0 SIGTERM", the numerical value of SIGTERM is left shifted by 8 and then stored in job->class->normalexit http://bazaar.launchpad.net/~upstart-devel/upstart/trunk/view/head:/init/parse_job.c#L2433 2. but when determining the appropriate log level, the value in job->class->normalexit is compared directly to numerical value of the signal, (without left shift the signal value) http://bazaar.launchpad.net/~upstart-devel/upstart/trunk/view/head:/init/job_process.c#L1495 When using "normal exit 0 SIGTERM 15", both "15 << 8" and 15 will be stored in job->class->normalexit, the code to store 15 is at http://bazaar.launchpad.net/~upstart-devel/upstart/trunk/view/head:/init/parse_job.c#L2428 and thus later on the code to determine log level works. Note that "normal exit 0 SIGTERM" works well with "respawn", it is just the logging code has the minor bug said above. ** Affects: upstart (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1515060 Title: Wrong logging level when signal name (e.g., SIGTERM) is used with normal exit stanza To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/1515060/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
