1/** 2 * This is not the set of all possible signals. 3 * 4 * It IS, however, the set of all signals that trigger 5 * an exit on either Linux or BSD systems. Linux is a 6 * superset of the signal names supported on BSD, and 7 * the unknown signals just fail to register, so we can 8 * catch that easily enough. 9 * 10 * Windows signals are a different set, since there are 11 * signals that terminate Windows processes, but don't 12 * terminate (or don't even exist) on Posix systems. 13 * 14 * Don't bother with SIGKILL. It's uncatchable, which 15 * means that we can't fire any callbacks anyway. 16 * 17 * If a user does happen to register a handler on a non- 18 * fatal signal like SIGWINCH or something, and then 19 * exit, it'll end up firing `process.emit('exit')`, so 20 * the handler will be fired anyway. 21 * 22 * SIGBUS, SIGFPE, SIGSEGV and SIGILL, when not raised 23 * artificially, inherently leave the process in a 24 * state from which it is not safe to try and enter JS 25 * listeners. 26 */ 27export const signals = []; 28signals.push('SIGHUP', 'SIGINT', 'SIGTERM'); 29if (process.platform !== 'win32') { 30 signals.push('SIGALRM', 'SIGABRT', 'SIGVTALRM', 'SIGXCPU', 'SIGXFSZ', 'SIGUSR2', 'SIGTRAP', 'SIGSYS', 'SIGQUIT', 'SIGIOT' 31 // should detect profiler and enable/disable accordingly. 32 // see #21 33 // 'SIGPROF' 34 ); 35} 36if (process.platform === 'linux') { 37 signals.push('SIGIO', 'SIGPOLL', 'SIGPWR', 'SIGSTKFLT'); 38} 39//# sourceMappingURL=signals.js.map
