[mkgmap-dev] [mp: PATCH] Multipolygons: inner and nested polygons supported now

Sat Jan 2 11:17:16 GMT 2010

Ups, there must be some bug, or the code is very inefficient.

Austria compiled fine, but when I compiled Italy using this patch versus 
standard trunk. Usually the 16 tiles of italy compile in 8 minutes. Now 
it has compiled 6 tiles in 20 minutes only. However while 5 tiles 
compiled in normal speed, 1 took 10 minutes and currently it is stuck again.
It seems to get stuck on single tiles and max-jobs is then not 
continuing until the file it is stuck on finishes (only one instead of 2 
cpu cores used for a long time).

The one tile it took 10 minutes instead of 1 minute to compile, was also 
the only one with quite substantial size increase (5.07 to 5.20 MB).

I'll break the rendering now and delete the following line from my 
relations file, maybe this is causing it to go slow?
landuse=forest                         { apply { add landuse=forest; add 
name = '${name}'; add ref = '${ref}'    } }
