Policies
Policies are implemented throughout Shepherd to control the logic on choosing if there is sufficient data or how to merge overlapping programme data.
The following default policies are used when grabbing data and determining if there is any missing data.
To override the defaults, you may manually add a configuration directive into your local ~/.shepherd/shepherd.conf configuration file.
Note that we strongly discourage changing of default values unless you are really sure you know what you are doing! If you put some invalid syntax in the config file, shepherd may not work any more. If you get stuck, delete the ~/.shepherd/shepherd.conf configuration file and run ~/.shepherd/shepherd --configure to rebuild it.

$policy{timeslot_size} = (5 * 60); # 5 minute slots
$policy{timeslot_debug} = 0; # don't debug timeslot policy by default
# PEAK timeslots -
# between 4.30pm and 10.30pm every day, only allow a maximum of
# 15 minutes "programming data" missing
# if there is more than this, we will continue asking grabbers for more
# programming on this channel
$policy{peak_max_missing} = 15*60; # up to 15 mins max allowed missing
$policy{peak_start} = (16*(60*60))+(30*60); # 4.30pm
$policy{peak_stop} = (22*(60*60))+(30*60); # 10.30pm
# NON-PEAK timeslots -
# between midnight and 7.15am every day, only allow up to 6 hours missing
# if there is more than this, we will continue asking grabbers for more
# programming on this channel
$policy{nonpeak_max_missing} = 7*(60*60); # up to 6 hours can be missing
$policy{nonpeak_start} = 0; # midnight
$policy{nonpeak_stop} = (7*(60*60))+(15*60); # 7.15am
# all other timeslots - (7.15am-4.30pm, 10.30pm-midnight)
# allow up to 60 minutes maximum missing programming
$policy{other_max_missing} = 3*60*60; # up to 3 hrs max allowed missing
# if a postprocessor failed 5 times in a row, automatically disable it
$policy{postprocessor_disable_failure_threshold} = 5;
# don't accept programmes that last for longer than 8 hours.
$policy{max_programme_length} = (8 * 60 * 60); # 8 hours
The following default policies are used when reconciling data from multiple grabbers:
To override the defaults, you may manually add a configuration directive into your local ~/.shepherd/reconcilers/reconciler_mk2/reconciler_mk2.config configuration file in the setting_override section.
We strongly discourage changing of default values unless you are really sure you know what you are doing! If you put some invalid syntax in the config file, the reconciler may not work any more. If you get stuck, just delete the ~/.shepherd/reconcilers/reconciler_mk2/reconciler_mk2.config configuration file.
