win32utils devel - Feb 2008 - Taking a stab at a native windows timeout method

Hi all,

Charles O. Nutter posted an interesting entry regarding timeout.rb

http://headius.blogspot.com/2008/02/rubys-threadraise-threadkill-timeout
rb.html

Based on one of the followup comments I tried this:

require ''windows/synchronize''
require ''win32/event''

def wtimeout(sec, exception=Error)
   return yield if sec == nil or sec.zero?
   raise ThreadError, "timeout within critical session" if
Thread.critical
   begin
      terminate_event = Win32::Event.new
      x = Thread.current
      y = Thread.start {
         result = WaitForSingleObject(terminate_event.handle, sec *
1000) 
         if x.alive? && result == Win32::Event::TIMEOUT 
            x.raise exception, "execution expired"
         end
      }
      yield sec
   ensure
      if y and y.alive?
         terminate_event.set
      end 
   end
end

wtimeout(2){
   puts "Starting"
   sleep 5
   puts "Shouldn''t reach here"
}

But, it doesn''t seem to work. Any suggestions?

Thanks,

Dan
