[Tilesathome] another idea for more performance

[Frederik Ramm]

Hi,

> 1. Clients do not upload zoom z+1 blank if zoom z is blank.

This has been implemented on 08 March by Deelkar (r2239).

> 2. if server receives a blank_tile it removes all meta info and files

This is, to my knowledge, not currently implemented. However it is a 
rare case that an empty tile is uploaded where there was content before. 
It does happen and needs to be handled, but executing a bunch of 
"delete" requests each time an empty tile is uploaded might perhaps be 
overkill - maybe run a periodic job that checks wheter tiles with 
content exist below tiles without?

> Removing all files from disk is done today also, because clients upload

Has Deelkar's optimization been removed or disabled using the 
"renderFullTileset" option?

> Removing meta info is in svn will be in asap.
> For the switching phase we can decide on "vallidTileset" setting

I do not understand 100% what you want to say...?

Bye
Frederik
