SIGINT (Ctrl+C) and SIGTERM are not handled

When executing this file with c8 I get the coverage information.

function run() {
  if (1) {
    console.log(1);
  } else {
    console.log(2);
  }
}

run();

setTimeout(process.exit, 3000)

However if I kill the process using Ctrl+C before the timeout, I don’t get the coverage information for the code executed until that point.

Use case: I launch a service as a separate process and then launch integration tests (by sending requests to the service). Then I kill the service and check the coverage to make the tests pass. istanbul and nyc handle process kill correctly.

I created an issue for node: https://github.com/nodejs/node/issues/35212

Should c8 attach an event handler for SIGINT/SIGTERM etc. in the meantime ?

@bcoe @zbjornson Seems to be a node problem:

% NODE_V8_COVERAGE=/tmp/cov node /tmp/t.js

^C
% ls /tmp/cov
