Remove track_c tables
As far as I know, we don't use the track_c_* tables anymore (since at least 5 years).
They were initially used to analyse web traffic, but were very inefficient and tools like awstats (and now Piwik) demonstrated a much higher efficiency at doing the same thing.
This is why we should remove them (they confuse people as to why they are present).Actions to be taken:
- Check all references to these tables (make sure they are not used anymore)
- Eliminate the code that uses them
- Eliminate the tables (from db_stats.sql/db_main.sql and with a drop table in migrate-db)
- Make sure all database constants that relate to these tables are removed as well
Just to be safe, I'm talking about track_c_browsers, track_c_countries, track_c_os, track_c_providers, and track_c_referers
