Description

Appears to be a type of race condition when deleting recordings from "Finished" tab while TVH is recording multiple recordings at the same time. It doesn't always happen (hence belief it is a race condition) but is reasonably repeatable.

EDIT:

Through further testing I can confirm the behaviour is still the same while not recording. It seems to be more repeatable if selecting large selection (> 20) of finished recordings at a time.

I would happy to run a debug build to help identify if someone can help with guidance. Thanks

Unless you provide a stacktrace from a build with debug symbols nobody is able to see what's going wrong in your case.

No debug info provided, closed due to inactivity.

Happy to help try to debug. I'm using Docker for tvh and I had searched for image with debug symbols but wasn't successful in finding one with a recent build.

I'm currently using lscr.io/linuxserver/tvheadend:latest

Can you point me in the direction of Docker build with debug symbols?

Updated by Flole Systems over 2 years ago

Latest master is on GitHub, if you want to package it into a docker container it's up to you to do that. It's not officially supported or recommended to do that, so you're on your own.

#6

Updated by dj bloc over 2 years ago

As a workaround I've noted if I select multiple recordings (tested on 400+) on the Finished tab and select "Move to failed" and then delete them from the 'Failed Recordings' tab (again 400+ at once) TVH does not crash
