|
* This is not the set of all possible signals.
|
|
*
|
|
* It IS, however, the set of all signals that trigger
|
|
* an exit on either Linux or BSD systems. Linux is a
|
|
* superset of the signal names supported on BSD, and
|
|
* the unknown signals just fail to register, so we can
|
|
* catch that easily enough.
|
|
*
|
|
* Windows signals are a different set, since there are
|
|
* signals that terminate Windows processes, but don't
|
|
* terminate (or don't even exist) on Posix systems.
|
|
*
|
|
* Don't bother with SIGKILL. It's uncatchable, which
|
|
* means that we can't fire any callbacks anyway.
|
|
*
|
|
* If a user does happen to register a handler on a non-
|
|
* fatal signal like SIGWINCH or something, and then
|
|
* exit, it'll end up firing `process.emit('exit')`, so
|
|
* the handler will be fired anyway.
|
|
*
|
|
* SIGBUS, SIGFPE, SIGSEGV and SIGILL, when not raised
|
|
* artificially, inherently leave the process in a
|
|
* state from which it is not safe to try and enter JS
|
|
* listeners.
