[mythtv] code for user jobs only in front end?

Actually, no, I don't want to run jobs on the front end. They should run
on the back end that does the recording. The problem is that the back
end won't run user jobs; I created the user jobs as per the instructions,
and the back end won't run them. I posted messages in the users list, as
well as on mythtvtalk, but nobody had an answer. Which is why I started
digging into the code to try to solve it. And that's when I discovered
that the code: SLOT(doBeginUserJob1())); exists only on the front end;
not on the back end. (which didn't make sense to me) But in fact I
grep'd all the source code for the back end and can't find anywhere that
it launches user jobs. Could you tell me where in the back end code it's
supposed to start user jobs, so I can dig into why it's not working? I
only started digging into the code because this original post to the
users list was without a solution:
I have a bash script I want to be run when a recording has finished. I
added the user jobs in mythsetup, and when it didn't work, kept tweaking
the settings table directly, but with no luck. Here is what I've got:
select * from settings where value like '%userjob1%':
JobAllowUserJob1 1 mythbox
UserJob1 /usr/sbin/SaveMythRecording.sh %CHANID% %STARTTIME% %DIR%
AutoRunUserJob1 1 mythbox
UserJobDesc1 My user job mythbox
NOTE: I also added another set of duplicate records with hostname=null.
In my "record" table autouserjob1 is "1" for all shows. And I confirmed
in mythweb that it is checked. I've tried reloading the front end and
back end. And I've confirmed the permissions on the script allow
execution (ie -rwxr-xr-x). The bash script just contains a simple:
echo "$(date) $0-$1-$2-$3-$4" >> /home/donerecording.log
so I will know when the script is being run (my home directory has full
permissions). But that file is never created. In my mythbackend.log
when a recorded program is over there is no mention of the user job:

Anybody have any ideas? Thanks for any help.

The frontend doesn't run jobs. If you want to run any jobs on the
frontend, you need to either run mythbackend or mythjobqueue on the
machine as mythfrontend. It would be easy enough to add code to have
the frontend run the JobQueue as well, but it would also require some
logic added to default jobs to off for frontend-only machines so the
user would have to explicitly turn them on. I made a note in my TODO
about this, but it's not high on my priority list since mythjobqueue
Wherever you want to run them, you need to run mythtv-setup to allow
User Jobs to run on that particular host. But that is a -users
question and has been answered many times over so for more info look
the -users list archives for howto instructions.
