Tvheadend

Sounds like it might be a permissions issue. Make sure Tvheadend is fully started and has created the socket before you start to write to it. Having socat attempt to write to the socket before Tvheadend creates it may create one with permissions that differ from what it is expecting.

If your guide update is part ofa service or script, consider modifying it to check for the existence of the socket (and the proper permissions) before executing.

Another option is to use a tv_grab_file script that satisfies the minimum responses needed by XMLTV packages to simply cat your XML file to stdout.

I've tried removing the xmltv.sock and restarting but still this bad descriptor issue:

Jan 21 07:41:18 MAUKv6 tvheadend⁹³⁸¹: epggrab: module xmltv created
Jan 21 07:41:19 MAUKv6 tvheadend⁹³⁸¹: xmltv: xmltv: failed to listen on socket: Bad file descriptor

There is a small bug in the newest version.

In file src/epggrab/module.c find this line

if (listen(mod->sock, 5) != 0) {

and change it to

if (listen(sock, 5) != 0) {

This worked for me.

thanks for that - im having a little bit of trouble finding that file though?

upgraded this morning:

tvheadend -v
tvheadend: version 4.3-995~g9bdd747

still the same issue:

tvheadend[17793]: xmltv: xmltv: failed to listen on socket: Bad file descriptor

After heavy use of locate and grep -R i've still been unable to find where to modify:

if (listen(sock, 5) != 0) {


Anything i'm missing?

For now I have switched from using socat and instead have modified tv_grab_file to cat the same xml - this seems to be working fine.

In order to patch the file to have to grab the tvheadend source via git and compile yourself.

Do you know what version of master i need to downgrade to before that change to module.c was made?
I see that someone put in the patch request today:

Unless you are somewhat of a Linux geek you probably aren't going to do that. Many, probably most Tvheadend users just get the precompiled version from the APT Repositories (https://tvheadend.org/projects/tvheadend/wiki/AptRepository) or one of the other repositories (https://tvheadend.org/projects/tvheadend/wiki/download).

For now probably the easiest solution, assuming you're not well-versed in the ways of Linux, would be to switch to using the tv_grab_file grabber script as suggested earlier in this thread. There are links to instructions for doing that in other recent threads on this board (posts within the last few days even). I've never had any problem using tv_grab_file to import XML listings into Tvheadend. It's a little different than using sockets (which is something I was never able to get working, though I didn't try very hard after the first failure), mainly because you need to set up Tvheadend to run the grabber on a specific schedule, but I just run my cron job to get the listings in the early AM hours, and then have Tvheadend run the grabber script several minutes later.

Of course if the very idea of compiling software doesn't cause you to break into a cold sweat, feel free to go for it.

actually it looks like the xmltv.sock issue has been fixed in most recent version. i just updated in the last half hour and now it is going through correctly.
