[mkgmap-dev] Precompiled boundary files in one zip file

Sun Feb 12 20:46:08 GMT 2012

Hi WanMil,

I am still busy rewriting all the boundary code to allow reading bnd data
from zip.
Most of it is done, and I also found a few errors contained in my patch
boundary_prep_quadtree_v2.patch

I have now a version that can read old bnd format, new quadtree bnd file
format,
both from zip or normal directory, and its BoundaryQuadtree delivers the
same results as the 
version in the performance branch. 
I did not see a big difference between reading from zip or directory, I
think that is okay.
I did not see any multi-threading problems while reading from zip, so I did
not code anything
special for this. You mentioned such problems, did you mean updating zip
files?

I don't think that we need a routine to write / create zip files, do we?
I think we need a utility similar to BoundaryMerger to allow creating the
bnd files for planet in multiple steps, so that's what I am working on now. 

Gerd
