DevOpsCon 2021 (Unix Signals)
This repo serves as an example of what happens when processes don't define signal handlers.
Getting Started
There is a shell.nix file here, if you are running Nix / NixOS (not as in *NIX!)
There is a Makefile that will help you out:
make server-no-handler will start the process without a signal handler for SIGINT
make server-with-handler will start the process with a signal handler for SIGINT
make request will run curl localhost:8888
The server will always wait 10 seconds before returning content.
To have the example "work", in the terminal / shell running the server, hit Control-C after
you've ran make server-no-handler or make server-with-handler.
In the server-no-handler example, you'll see cURL error out.
In the server-with-handler example, you'll see the server wait and finish the request before exiting.
