[Opensim-dev] Opensim database management - garbage collection

[Ai Austin]

I wonder if someone can summarise for me the way in which Opensim 
manages old inaccessible assets... Are they removed from the daya 
base (e.g. when MySQL is used. We started with a completely fresh 
copy of Opensim, bare, no content a few days ago, and only 2 or 3 of 
the avatars are active at present.  We already have a 100MB MySQL data base...

A. A specific question on textures... I ended up at one stage with 
two copies with unique UUIDs of several textures, and then tidied up 
so all objects only use one,  then I deleted the second copy of the 
100 or so textures.  I.e. if someone uploads a texture, perhaps uses 
it on an object that is then deleted, and then delete a texture, is 
it removed from the database... or can it persist and be there forever?

B. Are temporary map images always deleted as a map refresh of a 
region is done, or do they stick around?
