/usr/bin/vendor_perl/tv_find_grabbers

tim carlin

I have what appears to be a very subtle configuration problem tvheadend and tv_find_grabbers. The service is running on Arch Linux. If I run tvheadend by hand using the following command as the user root or hts:

/usr/local/bin/tvheadend  -f  -p /run/tvheadend.pid -C -u hts -g video

everything works fine. In particular I see the following in the log:

However if I use the command:

systemctl start tvheadend

the log file shows:

When running the server by hand in the web interface for:
Configuration->Channel/EPG->EPG Grabber

the Internal Grabber Module is XMLTV: North America (Data Direct)

however it is Disabled when run using systemctl.

As far as I can tell I don't have a PATH problem as echo $PATH for both root and hts return the same value. And the tv_grab conf file appears to be accessible:


-rw-r--r-- 1 hts video  626 Apr  9 11:53 tv_grab_na_dd.conf

as is the tv_grab executable:


$ ls -l //usr/bin/vendor_perl/tv_find_grabbers
-r-xr-xr-x 1 root video 7588 Feb 12 09:43 //usr/bin/vendor_perl/tv_find_grabbers

I'm guessing this is something simple and I'm just not looking at the correct file/path etc.

Any thoughts greatly appreciated!

have you found a solution for the problem?

It is a strange behaviour, I've fixed it creating an hard link to tv_find_grabbers in /usb/bin with the command

ln /usr/bin/vendor_perl/tv_find_grabbers/usr/bin/

and for all the grabbers that You need, eg

ln /usr/bin/vendor_perl/tv_grab_it /usr/bin/

If you do so, tvheadend shows two times all grabbers that You created the link.

Maybe a move command sholud avoid the duplications, but I don't want to move the original file.

It seems that in some file tv_grab_XX are missing following two lines, just after the first line "*#!/usr/bin/perl*":

eval 'exec /usr/bin/perl -S $0 ${1+"$@"}'

if 0; # not running under some shell

I guess that this is for avoid to execute the command using bash.

Best regards

The problem is the way that Arch does perl. When you log in it properly adds the perl directories to the path. But with services where it is run as a user that doesn't load a .profile the path doesn't get set. You can modify the settings or service file to include the perl directories in your path, or—what I do and was previously mentioned—link the grabbers into /usr/bin.
