[Win32utils-devel] [ win32utils-Support Requests-8957 ] Killing grandchildren?
Support Requests item #8957, was opened at 2007-02-28 13:47 You can respond by visiting: http://rubyforge.org/tracker/?func=detail&atid=412&aid=8957&group_id=85 Category: win32-process Group: None Status: Open Resolution: None Priority: 3 Submitted By: Chad Woolley (thewoolleyman) Assigned to: Nobody (None) Summary: Killing grandchildren? Initial Comment: I am trying to spawn, then kill, a gem_server process. On windows, however, this actually spawns a child cmd instance for the gem_installer.bat file, which then spawns a grandchild ruby process for the gem_server command. I can''t figure out how to make the grandchild process die. If I could get it''s PID, I could kill it, but I only have the pid of the child process. If I kill the child, then the grandchild is not killed, but stays alive, and is owned by the top-level cmd shell process. Here''s the file where I am trying to do this: http://rubyforge.org/viewvc/trunk/spec/helper/embedded_gem_server.rb?revision=353&root=geminstaller&view=markup Thanks, Chad ---------------------------------------------------------------------- You can respond by visiting: http://rubyforge.org/tracker/?func=detail&atid=412&aid=8957&group_id=85

However, since it appears that you''re trying to daemonize a gem_server, I recommed using the ruby-services package. It has services for gems, webrick and fastri. Install the gem service, and control it that way instead. It''s what I do.
