Make python invocation work with bash exec

[irismessage]

Currently, when using this egg, the "Stop" button in the panel will absolutely not work. This is because the stop button sends a SIGTERM signal to the Bash process, and the Bash process will ignore the SIGTERM without propagating it to the Python process.

By adding exec, the Bash process will be completely replaced by the Python process, so the SIGTERM will reach the Python process and it will terminate normally.

P.S. I just had a situation where the panel registered the server as completely shut down but the server was still up and running. Please fix it

It would also be nice if the documentation had details about what signals are being sent, and to where, when I click the Stop button, but that's a matter for another repo

This won't work as the entire command is wrapped in an eval as part of the image.

I have a PR for wings to make it possible to use exec but that is still in progress.

do you have a preffered solution in the meantime? thinking of swapping out the bash binary

You can always try to set the stop cmd to ^^C

swapping out the bash binary

Swapping out bash wont fix it as the eval is in the start script
