Tvheadend

In autorec mode the ~/.hts/tvheadend/dvr/log/ files are written it first pops up on EIT, which is 3AM here:

Jan 08 03:01:32 soekris tvheadend¹⁰⁶⁸⁶: dvr: "Mythbusters" on "Discovery Channel HD" starting at 2013-01-11 13:09:00, scheduled for recording by "Auto recording by: koen"
Jan 08 03:01:32 soekris tvheadend¹⁰⁶⁸⁶: Jan 08 03:01:32 [INFO]:dvr: "Mythbusters" on "Discovery Channel HD" starting at 2013-01-11 13:09:00, scheduled for recording by "Auto recording by: koen"

At that point it only has the basic EIT info, not the complete one that will be added approximately 24 hours before the recording.

So it looks like this will only happen for autorec recordings.

I have found a workaround, this cronjob runs at 7 in the morning each day:

for file in $(ls /home/root/.hts/tvheadend/dvr/log) ; do
if grep -q "filename" $file ; then
echo Recording present $(basename $file): $(grep filename $file | awk -F: '{print $2}')
else
rm $file
fi
done

killall tvheadend

Systemd will restart tvheadend automatically which will restore the autorec entries, this time with proper metadata.

Yesterday I was trapped by another sideeffect of this bug:
If a schedule of an autorec happens to fire after i.e. a footbol game, which extends about an hour, time entries of the epg-event will change (multiple times probabely), but the recording will be performed with the old timings, resulting in a broken recording.

Channel was SF2 at Fri 4/12 00:10 - no external epg.
