TODO: Need improvements for handling of whitelists and blacklists upon import/refresh

[pschneider1968]

Currently upon refresh, we nuke (=completely replace) all whitelists and blacklists from our files. This might not be what the user wants, because he or she might have setup whitelists and/or blacklists of his/her own.

So we need to implement a better way to deal with these lists. Probably some logic like the ADD/MERGE/DELETE/FULL mode for the list_of_blocklists.txt file.

However this is complicated by the fact that for white-/blacklists, stored in the domains table in the Gravity DB, we have no master table like we have for adlists->gravity so there is no possibilty yet to have white-/blacklists grouped together and identify them as a collection of entries.

So probably this needs to be addressed as an enhancement request to upstream Pi-Hole developers.

If so, I will link to relevant communication with upstream here.

Probably, this could be handled by making use of the Groups feature, although this was meant for a completely different purpose, i.e.for mapping clients to rules/rule sets.

Still open...
