Killing detached process

[Joel Wurtz]

Actually killing a process which is detached does not work

$process = new \Amp\Process\Process("setsid sleep 100");
$process->start();

$pid = yield $process->getPid();

$process->kill();

Then doing a ps aufx|grep sleep show the process still running, it is possible to kill him since we have the correct id and we can use then posix_kill, but should we do that (it introduce maybe a new extension dependency)

I'm not sure whether it's out job to kill a process which detached. STDIO and everything else still works fine for such a process?

[Joel Wurtz]

Maybe not our job, but some users may not be aware that the process they launch will be detached, so maybe throwing an exception when trying to kill him or having a specific state ?

[Niklas Keller]

The thing is that the process the user actually launched is sh -c, we already do tricks to get the real processes PID. We should probably use that PID for sending signals, so that'd include kill() then.
