Can't kill child process

[vojtajina]

// node.js
var spawn = require('child_process').spawn;
var p = spawn('/usr/bin/firefox', ['http://localhost/']);

setTimeout(function() {
  p.kill();
}, 1000);

p.on('exit', function(code, signal) {
  // will never happen
});

Please be more specific. There is nothing in the travis CI env that traps signals so I doubt this can qualify as a travis issue. For questions, use the mailing list.

I seem to have a similar issue with https://travis-ci.org/TypeStrong/ts-node/builds/273609445; for what it is worth, switching the default shell used by node from sh to /bin/bash seems to have some impact: https://travis-ci.org/TypeStrong/ts-node/jobs/273612209

Is it possible that Travis does something special with sh?

https://travis-ci.org/thomasfl/filewatcher/jobs/298238166

I'm spawning /home/travis/build/thomasfl/filewatcher/bin/filewatcher executable via Kernel#spawn, but it runs that executable through sh -c and returning this sh -c pid, which ignoring SIGHUP, SIGINT or SIGTERM on it and its child normal ruby process.
