John Sirois commented on AURORA-1572:
-------------------------------------
The example you give does not seem to match the description well. In your
example only {{cmd0}} is an active process when the signal is received ({{&&}}
chain, not a pipeline, etc). As such - even if SIGTERM were sent to the full
process tree - that's still just {{cmd0}} here and if it handles the signal by
not exiting 0, the {{&&}} chain will continue on to {{cmd1}}, etc.
> SIGTERM is not sent to child processes

> In terminate_process, SIGTERM is sent to the parent process only. This seems
> like a deliberate design choice given that the kill_process does send a
> SIGKILL to each child process. Is there a reason why SIGTERM is not also sent
> the to child processes?
> For reference, I'm referring to the functions defined in the thermos
> helper.py file.
