// 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.
|
||
|
|
//
|
||
|
|
// 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.
