Why I did it
Sometime, SIGTERM processing by psud takes more then default 10sec (please see stopwaitsecs in http://supervisord.org/configuration.html).
Due to this, the following two testcases may fail:
Also, limited
get_bmc_version()execution time to 1 sec.How I did it
Introduced two levels of SIGTERM handlers:
signal_handler()that executes a default handler (psudSIGTERM handler) and avoids subsequentpsu_info_get()executions.cancel_on_sigterm()decorator that executes class levelsignal_handler()and raises an exception to cancel currentpsu_info_get()execution.How to verify it
Run SONiC CTs:
