Tilesorigin is confusing, key the meta tile cache by bbox only and do meta
tiling with tiled=true alone
-------------------------------------------------------------------------------------------------------
Key: GEOS-2741
URL: http://jira.codehaus.org/browse/GEOS-2741
Project: GeoServer
Issue Type: Improvement
Affects Versions: 1.7.3
Reporter: Andrea Aime
Assignee: Andrea Aime
Fix For: 1.7.4
People keep on getting confused by tilesorigin usage, only the map previous
seems to be using it in a competent way.
So get rid of it. A way to cache the tiles is by pure bbox:
- if the cache does not contain the bbox (minus a small tolerance, say +/- 1%)
create a new 3x3 metatile with the requested tile in the middle
- if other request hit a bbox of a tile inside a meta tile that is being
computed, make them wait
- once computed, cache each tile separately
This way we should have a system that works with tiled=true only.
