FetchInventory() on TPs/crossings is no more!
FYI, I have my local mods available in github:
http://github.com/diva/Diva-s-OpenSim-Tests/tree/master
In this code, the simulators don't load/cache inventory, they just
pre-fetch a very small amount of info (the avie's "system" folders).
Virtually all core code, with 2 exceptions(*), has been redirected from
facing an inventory cache (CachedUserInfo) to facing the inventory
service interface. The new, minimal cache is transparent to the core code.
If anyone cares to test this, I will appreciate it. Since it's not
coming from opensim.org, it will be a bit more cumbersome, but it's
worth experimenting with this new git-enabled process.
(*) Features I didn't touch: IAR module and the Rest Inventory plugin.
These still work as before, bringing the entire inventory to the regions
