Hi all, there's a one-line bug fix that can be made to newdb.cpp that enables previously-written world cleanup features to function. This will free up apartment leases and get rid of the *** OVERFLOW *** in the newbie garage. I've outlined it below:
In the newdb.cpp function does_player_exist(long id):
Change
| Code: | | sprintf(buf, "SELECT idnum FROM pfiles WHERE idnum=%ld;", id); |
To
| Code: | | sprintf(buf, "SELECT idnum FROM pfiles WHERE idnum=%ld AND name != 'deleted';", id); |
This lets the code differentiate between active and deleted chars when looking up by ID, which in turn triggers the automatic purging of deleted characters' leases, vehicles etc.

Looked into this further-- it will also remove deleted chars from guest lists and remove their old shop orders. I suspect that this change will result in significant disk space and save/load time savings due to all the things that will be cleared out here.
I've also analyzed the code for all usages of this function and outlined the impact here to demonstrate that there should be no adverse impact to this change.
This change will impact:
db.cpp's vehicle and order loading (deleted chars' vehs and orders won't load)
house.cpp's guest loading (deleted guests will be wiped) and apartment records (deleted owners will lose their lease)
limits.cpp's vehicle saving (deleted chars' vehs will not save)
This change will not impact:
act.wizard.cpp's do_stat and do_last (these use names instead of IDs)
interpreter's CON_GET_NAME loading (uses name instead of ID)

This fix was implemented today-- thanks Che! Newbie garage went from ** OVERFLOW ** to 12 vehicles, and there are once again free apartments at the various complexes.
