None in the config, but the script needs to change.
There is a new env variable, "$client_connect_deferred_file", which
controls if the server can do it (2.5 and up) - so the script might
want to check that
# redirect output so we can see it in the cc.log
exec >>/my/private/tmp/cc.log 2>&1
# tell server we want deferred handling (= it should regularily
# check that file for updates
echo 2 >$client_connect_deferred_file
# child process - simple shell backgrounding here
(
echo "backgrounded..."
# do mighty important work
sleep 10
if [ something failed ]
echo "async done, signal FAIL!"
ret=0
else
echo "async done, signal success!"
ret=1
fi
# this is how the server knows -> the "2" changes to "0" or "1"
# in that file
echo $ret >$client_connect_deferred_file
) &
# parent process must "exit 0" (with "2" in the file) to signal "defer OK"
exit 0
The manpage (... saga) also has more material on this, if you know to
search for "client_connect_deferred_file" :-)
Feel free to be very confused by the available documentation, and in
the end suggest wording that helps find your way more easily. Arne and
I have done our best, but it might still be confusing.
