Ruby as Windows Service

[Mehr, Assaph (Assaph)]

Hi All,

I almost got to the point where I can install any ruby program as a
Windows
service. I do this using cygwin. For example to install Instiki as a
service:

$ cygrunsrv --instal Instiki --path c:/ruby/bin/ruby.exe --args
c:/Stuff/instiki-0.9.1/instiki.rb

The executable for the service (--path) is my Win32 (not cygwin's) Ruby
executable. The argument is the name of the ruby script to run.

The service installs and start fine, but cannot be stopped (the process
has
to be manually killed). I have tried specifying various termination
signals
(using --termsig) and using a Kernel#trap to respond to them, but the
trap
is never executed, and the process doesn't stop. E.g.:
trap("TERM") { @server.shutdown; exit(0) }

The only signal that stops the process is SIGSEGV, which isn't very nice
.
Besides, even traps for it don't work.

Any clues as to how to fix?


Cheers,
Assaph

Not exactly what you're asking for, but there used to be a program
that came with the Windows NT resource kit called "srvany.exe". It
does the same thing as the cygwin program, but it doesn't use Cygwin.
I wonder if it would work better for you? It apparently works on all
of the newer versions of Windows, too. I'm not sure where you could
get it now, though.

It's probably due to the fact that the Ruby interpreter
releases control to Windows when it waits for events. So you
have to have an event on a regular basis...

I've had the same problem with a TCPServer and came up with the
following hack:

# The hack...

def self.trap(signal)
Kernel::trap(signal){yield}
Thread.new{loop{sleep 1}} # Stupid Windows...
end

# Doesn't work with Kernel.trap .
# Try it!

trap("INT"){puts "Terminating..." ; exit}

# Just a demo...

require "socket"
puts "Hit ^C..."
TCPServer.new("0.0.0.0", 1234).accept

I have successfully used FireDaemon to run things as a service. Free for a
single service, low cost for multiple services.

I second the recommendation of FireDaemon - been using it for a month to
run Instiki, works like a charm.
