The code described above is now in CVS if people want to give it a shot and/or
write some new methods for determining what to auto-expire (like sort by
reverse recording rank maybe by storing the rank a program was recorded at).
The Auto-Expire code is turned OFF by default and the Default Auto-Expire
value for new recordings is OFF as well. So, to activate auto-expire, you
have to first go into the TV/General settings screen (2nd page) and turn
on Auto-Expire by setting the Disk Space Threshold to something > 0. If
the disk space threshold is set to 2 Gigs, then whenever the code checks
for free disk space and it's below 2 Gigs then the auto-expire process will
In order to give the auto-expire process some programs to expire, you have to
do a few things:
* Set "Auto-Expire Default" to ON if you want new scheduled programs
to be allowed to auto-expire by default
* Go into each previously entered scheduled program that you want to
allow to auto-expire and change it's Auto-Expire value to ON from
the advanced recording options screen.
* For old already-recorded programs, you can set them to Auto-Expire by
hitting 'I' on the playback or delete screens and saying 'Yes' to
allow that program to Auto-Expire.
The only current Auto-Expire method is Oldest First. So, the oldest recorded
program that has it's auto-expire value set to ON will be expired first.
If you want to see what order programs will be expired in, you can run
mythbackend with the --printexpire option and get a list. The last item
on the list is the one that will expire first.
The expire method and disk space threshold are Global settings so they apply
to each backend, but each backend server runs its own auto-expire process and
will only Auto-Expire programs that it has recorded.
