User job

I have setup a user job to export using the script ipod_export.pl from the
mythtv wiki. On myth 0.25 fixes I always get a user job failed. This is the
exact same Job I had running on Mythtv 0.24 Fixes. Has anyone else seen
this issue? What changed or what do I need to change?

I forgot to add, If I run the same command mythtv does on the linux command
line it works just fine.

Hi;

Also, if you type: echo $? after your command line test, you'll
see its exit code, although you'd expect any failure in the
script to print a message.

I'm not sure if: mythbackend --setverbose system will give you
more information that the log you pasted in your 1st post,
but it can't hurt (there's: --setloglevel debug too.)

The library for external system calls does not currently log output from
external scripts. The scripts themselves are expected to handle all
logging internally, and MythTV discards any stdout/stderr to /dev/null.

What has me banging my head against the wall is the script ruins outside
mythtv's job queue, but not if it is run by the job queue.

OK, if the return code is 0 on when run from the command line, then
is there a difference between the user running the command? Probably
mythtv when the backend runs it and your own user name when run from
the command line.

diff ~mythtv/.mythtv/mysql.txt ~/.mythtv/mysql.txt

for example.

Or environment variables. This has been pointed out as a possible reason for
some other discrepancies. How is $HOME set, for example, in each case? Other
variables which may differ according to how the script is run and from where?

when I get home this evening from work I will check out the above suggests.

Just for further information the ipodexport.pl does not exit until the job
is complete. Matter of fact when run from the Mythtv job queue it never
actually starts the process of exporting. it immediately errors out.

Sort of seeing the same thing here. Script works fine when run by
25-fixes, but still shows up as failed. I guess I need to ignore the
red in the job queue. :-)

Ok. I was finally able to get a little more info. I will continue digging,
but here is what I have. My user job 3 looks like this normally:

/usr/local/bin/ipodexport.pl exportdir=/var/lib/mythtv/export
starttime=%STARTTIME% chanid=%CHANID% size=720x480 aspect=16:9
acodec=libaacplus

right now I have it set to look like this:

/usr/local/bin/ipod.sh exportdir=/var/lib/mythtv/export
starttime=%STARTTIME% chanid=%CHANID% size=720x480 aspect=16:9
acodec=libaacplus

the ipod.sh script looks like this.
------------------------------------------------------------------------------------------------
#!/bin/bash

echo "Environment variables:" > /tmp/export.log
export >> /tmp/export.log
echo "Exit status before export command $?" >> /tmp/export.log
echo "/usr/local/bin/ipodexport.pl $*" >> /tmp/export.log
/usr/local/bin/ipodexport.pl $*

ret=$?

echo "exit status after attempted export $ret" >> /tmp/export.log

------------------------------------------------------------------------------------------------

The export log contains the following.
---------------------------------------------------------
Environment variables:
declare -x AVAHI_COMPAT_NOWARN="1"
declare -x BOOT_IMAGE="MythTV"
declare -x CONSOLE="/dev/console"
declare -x HOME="/etc/mythtv"
declare -x INIT_VERSION="sysvinit-2.86"
declare -x MYTHCONFDIR="/etc/mythtv"
declare -x OLDPWD
declare -x PATH="/bin:/usr/bin:/sbin:/usr/sbin"
declare -x PREVLEVEL="N"
declare -x PWD="/"
declare -x RUNLEVEL="4"
declare -x SHLVL="4"
declare -x TERM="linux"
declare -x prevlevel="N"
declare -x runlevel="4"
Exit status before export command 0
/usr/local/bin/ipodexport.pl exportdir=/var/lib/mythtv/export
starttime=20120811183000 chanid=13888 size=720x480 aspect=
16:9
exit status after attempted export 255

---------------------------------------------------------

Now if i take the command line
"/usr/local/bin/ipodexport.plexportdir=/var/lib/mythtv/export
starttime=20120811183000 chanid=13888
size=720x480 aspect=16:9 acodec=libaacplus" and run it manually it works
fine.

I realize exit status 255 is special, but the point is the same. My
original job 3 fails, but if I use the same options and run it from the
command line it works fine. I am not sure how to see what error code the
myth job queue is giving. It never appears in my logs.

The command execute by your script is missing "acodec=libaacplus". Maybe
there is a size limit to the jobqueue command..

You could change the command in the wrapper script to something like
this: (so you can see whats going on withing ipodexport.pl)
/usr/local/bin/ipodexport.pl <http://ipodexport.pl> $* 1>
/tmp/ipodexport.log 2>&1

Or you could also change to the following:

*Myth Job Command*
/usr/local/bin/ipod.sh starttime=%STARTTIME% chanid=%CHANID%

*/usr/local/bin/ipod.sh*
#!/bin/bash

echo "Environment variables:" > /tmp/export.log
export >> /tmp/export.log
echo "Exit status before export command $?" >> /tmp/export.log
echo "/usr/local/bin/ipodexport.pl <http://ipodexport.pl> $*" >>
/tmp/export.log
/usr/local/bin/ipodexport.pl <http://ipodexport.pl>
exportdir=/var/lib/mythtv/export $* size=720x480 aspect=16:9

ret=$?
