Auction House DataBase (AHDB)


Auction House DataBase

Auction House DataBase (AHDB for short), records DB history and allows offline queries, for classic and bcc.

This Open Source addon is mostly to capture the evolution of the WoW classic economy from empty to mature.

We have a unique chance to record that history and that's what this addon attempts to accomplish

As you might know the Blizzard APIs to query the AH from the web (like The Undermine Journal does for instance) won't exist at launch and for some undetermined time after launch, so let's together create and maintain that DataBase.  (DB uploader in the works)

What does it do?

AHDB shows a (moveable) button to take the next step (target the auctioneer, start scan, save,...)

If you configured it to do so, each time you open the auction house (if available and unless you the hold shift key), AHDB takes a full snapshot of your auction house and record it in your saved variables under the realm, faction and timestamp

You will be able to later query that DB even when not at the AH

Note: AHDB is unrelated to TSM's internal module AuctionDB (though there is a basic integration and TSM can now use some of our awesome scan data)

  • No more pause/hang on classic at the end of the first scan!
  • Unlike in BfA which doesn't mind despite 100x more items, for classic we needed to not restorethe item update event immediately, yet keep the UI functional even if you search afterand hit enter in Name editbox for instance (still haven't found how to hide previous resultsif you manual search first and then do a full scan but it's only cosmetically wrong in that case)
