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". As it stands now, manually stopping and
starting Tomcat with jsvc hangs my ssh session on logout, since it still has
open files to the pty.
3) Modify Tomcat.sh to reflect the changes in 2) (e.g. add:
-outfile $CATALINA_HOME/logs/catalina.out \
-errfile &1 \
).

Oops I was a bit to fast in my answer and have though of a setuid().
Of course the setsid() is _missing_ in the actual daemon code.
So you have my +1, sorry for the bad comment.

I don't understand. setsid doesn't change the identity, it just puts the
(forked) process into a new session, and divorces it from the pty. The
process is still running as "root". It's similar to (or, rather, a subset
of) the Linux "daemon" API call. Since it is good enough for Apache/httpd,
I really didn't expect any controversy on this one.
The problem is that the monitor still gets signals from my terminal session
(including HUP when I try to logout). Similar to below, it hangs my ssh
session, since there is still an active proc in the same session as mine
when I try to logout.

Tell what goes wrong we should fix it.

I have already explain why I am against this idea. I would like to see daemon
promoted to common-daemon. For the moment I am trying to fix the stop of procrun
in win9x.
BTW: I have added reflexion and now daemon could be used to start Tomcat5.
and would like to see daemon promote to common-daemon.

I know this has been discussed several times - but wouldn't be time to move
the daemon back to tomcat ? Maybe we made a mistake by trying to move it to
commons, it doesn't seem to gain a lot of developers or users outside
tomcat.
