Ability to send SIGTERM or SIGINT to Processes started by dart

[efortuna]

Currently, if you create a Process, your only have two ways to end the proces: close() and kill(). Kill sends a SIGKILL signal, and close seems to just close the input/output streams without sending any signal. We'd like the functionality to also send signals like SIGINT to Processes we create in Dart.

We can definitely add support for sending signals to processes. Could you give me more information about the use case for this? Sending SIGINT is Linux/Mac specific so I would like to figure out if we can provide something else that will cover your needs in a platform independent way. I do see the use case for sending signals on Mac and Linux but would like to understand if there is something else we can do for this particular case that would work on all platforms.

The use case is to kill a process in the default Linux/Mac way (SIGTERM). This is preferred because the process can implement cleanup logic.

e.g. http://nodejs.org/docs/latest/api/child_processes.html#child.kill

Fixed in http://code.google.com/p/dart/source/detail?r=8541

Default kill is now SIGTERM, while it's possible to provide another. This argument is ignored on windows.
