- Category set to EPG
- Status changed from New to Need feedback
- Assignee set to Adam Sutton
Yeah there have been a couple of reports, trying to determine whether it was the EIT mods or the minor mod to EPG scheduling timer. Neither of which should cause this.
If someone can get a GDB trace (bt full) that would really help.
Adam
P.S.
To all: when reporting issues please but the full version (with git hash'ish) in the found version, it really helps.
George,
Thanks, that's perfect. I think I might have figured out what's going on. I'll get back when I've had a chance to check it through. I might not be able to test as it's not happening on my system and I think it will be specific to certain setups.
What I'll do is generate a fix and post it here for you and the others to try.
Regards
Adam
You're more than welcome Adam. I really like your work on TVH. Thanks a lot for that.
Try this branch on my fork:
https://github.com/adamsutton/tvheadend/tree/issue/redmine-1257
I had failed to clear a couple of ptrs that no longer pointed to valid objects, previously this was fine as they were never used before the relevant ptrs were correctly updated. However to solve a minor issue in new HTSP code for another dev I was not accessing the ptrs and causing it to crash.
Hopefully this will fix the issue.
Adam
Might be a mistake in my fork, I thought I synced it with master before that commit. I'll check.
Adam
Hi Adam,
I just changed the my master clone from GIT with your changes to src/epg.c I found in your fork and compiled. It works like it should now.
Regards,
George
OK, I'll submit the fix to tvheadend/master.
Adam
