[mkgmap-dev] Error in memory calculation

Wed Feb 5 15:26:30 GMT 2020

Hi Ticker,

OK, I think it's best when I change the code so that we have a method that computes the flags IN,ON,OUT, and maybe something else about polygons in holes. Input parameters are ElementQuadTree qt and the Element el.
This is required anyway to allow unit tests.

The code in IsInFunction.java should only implement  the "user interface" and evaluates the result. I'd be happy when you create that part.

Gerd

Hi Gerd

I don't have a 64bit environment or that much memory. In my normal
environment, I get:

$ java -Xms1500M -Xmx1540M -jar ../mkgmap.trunk/mkgmap.jar \
  dummy.osm dummy.osm dummy.osm
Time started: Wed Feb 05 12:56:28 GMT 2020
Setting max-jobs to 4
Number of MapFailedExceptions: 0
Number of ExitExceptions: 0
Time finished: Wed Feb 05 12:56:29 GMT 2020
Total time taken: 1 second

-Xmx1540M is the maximum value that allows Java to start up on my
machine.

With a newer version I loaded in October, but it didn't have any
obvious advantages:

$ /opt/jre1.8.0_231/bin/java -Xms1500M -Xmx1540M \
  -jar ../mkgmap.trunk/mkgmap.jar \
  dummy.osm dummy.osm dummy.osm
Time started: Wed Feb 05 12:58:29 GMT 2020
Setting max-jobs to 4
Number of MapFailedExceptions: 0
Number of ExitExceptions: 0
Time finished: Wed Feb 05 12:58:30 GMT 2020
Total time taken: 1 second
