Siri,
Anything else need to be done to graduate/merge this patch?
Thanks.

However, catching this is not at all necessary here, since it will be catched by the rpc:call anyway - it will return {badrpc, {'EXIT', {suspended_supervisor, _}}} .

I know that there will be error messages in the shell, but I find it better if even the returned error reason gives a hint about what failed. My suggestions for the three calls to error/1 respectively (please change if you have better ideas):

And hopefully you can use the functions create_and_install_fake_first_release and create_fake_upgrade_release - you can see examples of that in release_handler_SUITE.erl. Please let me know if you need any more advice on the testing.

Check out the commit message at https://github.com/joewilliams/otp/commit/9c3a53789326cdd929f1c3b4525716b1c0abfe87 for the details. In both cases I found that in production an error in the logs was preferable to the restart of the VM since both are easily fixable with a small application change or in the case of the suspended supervisor using a different app up. Also see this comment in release_handler_1 regarding the supervisor, https://github.com/erlang/otp/blob/dev/lib/sasl/src/release_handler_1.erl#L454 which suggests this corner case is known by at least a few people. Currently there is no way to know *why* your VM just restarted after the upgrade in either case.

I agree that the timeout and VM restart is not very good, and it makes sense to check if the supervisor is suspended. But I'm not really sure if it is correct to allow the upgrade to continue when this error occurs. Even if an error message is printed, I guess it could be quite easy to miss this fact... and the question is if that would be a problem or not? Why is the supervisor suspended in the first place?
