Cool. +1. I also agree with keeping daemon in the commons and possibly promoting it out of the sandbox into commons-proper. I think the functionality it offers is generic beyond tomcat, and I for one plan to use it for things other than tomcat. ;) Yoav Shapira This e-mail, including any attachments, is a confidential business communication, and may contain information that is confidential, proprietary and/or privileged.

commons-sandbox/daemon
Ok, yes I know that this should go to commons-dev, but I don't monitor that list as closely and all of the active developers hang-out here. I would like to make some changes to native/unix/native, and (keeping with commons conventions) should ask first. I already have commons-sandbox karma, so that's not an issue. 1) I want to call setsid (on platforms that support it) after the detach, since evil things happen if I don't (at least on RH Linux). 2) I want to add a -outfile and -errfile to the config options (consistant with procrun, and both defaulting to /dev/null). stdin will get redirected to /dev/null, and stdout & stderr will get redirected to the values of the variables. If I can get it to work, I'd also like to add the special values "&1" and "&2" to simulate "2>&1".
