Java: incorrect signal numbers #54

Open jamesjer opened 3 years ago

jamesjer commented 3 years ago

I was just looking at the signal numbers in runtime/Jlib/foreign.java. The values for SIGQUIT and SIGINT are reversed, and several of the others are system-dependent. For example, the values of signals up to number 31 would look like this on BSD systems:

   public static final int SIGHUP = 1;
   public static final int SIGINT = 2;
   public static final int SIGQUIT = 3;
   public static final int SIGILL = 4;
   public static final int SIGTRAP = 5;
   public static final int SIGABRT = 6;
   public static final int SIGEMT = 7;
   public static final int SIGFPE = 8;
   public static final int SIGKILL = 9;
   public static final int SIGBUS = 10;
   public static final int SIGSEGV = 11;
   public static final int SIGSYS = 12;
   public static final int SIGPIPE = 13;
   public static final int SIGALRM = 14;
   public static final int SIGTERM = 15;
   public static final int SIGURG = 16;
   public static final int SIGSTOP = 17;
   public static final int SIGTSTP = 18;
   public static final int SIGCONT = 19;
   public static final int SIGCHLD = 20;
   public static final int SIGTTIN = 21;
   public static final int SIGTTOU = 22;
   public static final int SIGIO = 23;
   public static final int SIGXCPU = 24;
   public static final int SIGXFSZ = 25;
   public static final int SIGVTALRM = 26;
   public static final int SIGPROF = 27;
   public static final int SIGWINCH = 28;
   public static final int SIGINFO = 29;
   public static final int SIGUSR1 = 30;
   public static final int SIGUSR2 = 31;

and like this on Linux systems:

   public static final int SIGHUP = 1;
   public static final int SIGINT = 2;
   public static final int SIGQUIT = 3;
   public static final int SIGILL = 4;
   public static final int SIGTRAP = 5;
   public static final int SIGABRT = 6;
   public static final int SIGBUS = 7;
   public static final int SIGFPE = 8;
   public static final int SIGKILL = 9;
   public static final int SIGUSR1 = 10;
   public static final int SIGSEGV = 11;
   public static final int SIGUSR2 = 12;
   public static final int SIGPIPE = 13;
   public static final int SIGALRM = 14;
   public static final int SIGTERM = 15;
   public static final int SIGSTKFLT = 16;
   public static final int SIGCHLD = 17;
   public static final int SIGCONT = 18;
   public static final int SIGSTOP = 19;
   public static final int SIGTSTP = 20;
   public static final int SIGTTIN = 21;
   public static final int SIGTTOU = 22;
   public static final int SIGURG = 23;
   public static final int SIGXCPU = 24;
   public static final int SIGXFSZ = 25;
   public static final int SIGVTALRM = 26;
   public static final int SIGPROF = 27;
   public static final int SIGWINCH = 28;
   public static final int SIGPOLL = 29;
   public static final int SIGPWR = 30;
   public static final int SIGSYS = 31;

Hi Jerry,

I realized that I have never answered your comment. Actually, I don't know how to address the problem you are mentioning. Do you have suggestions?
