Hi, operating a own mapnik-tiles-generating server I needed a script which re-renders expired tiles in an easy way based on the expired-list osm2pgsql creates optionally. To avoid confusion and due to the rewrite done I called it mtilegenerator.py. First information about it and the code you may find on http://wiki.openstreetmap.org/wiki/User:Bettercom
Some changes made (which at least I need for calling the script from other scripts): * getopt-style driven (so probably not working on Win) * creates symlinks for "naked" water- and land-tiles (a 302-redirect would be another improvement but this is a webserver-issue) * tiles to be rendered may be defined via geographic X/Y or via Tilenumber (i.e. Z=10, X=300, Y=200) * Overwriting existing tiles is an option * When defining a range of zoomlevels to be rendered rendering is done like ti...@home: At first the tile at maxZoom-level is rendered and then all childs of it and so on. I will try to get some stats whether this could improve DB-performance (because the result of the query for the the parent tile still is in PG-cache).
