[mkgmap-dev] Regression causing Heap space exhaustion?From Greg Troxel gdt at ir.bbn.com on Sat Aug 22 12:17:50 BST 2009
The reason for the high memory usage is that most nodes in the Danish extract look like this: <node id='342123311' lat='55.3401904' lon='9.4886152'> <tag k='addr:postcode' v='6070'/> <tag k='kms:zip_no' v='6070'/> <tag k='kms:street_name' v='Seggelund Hovedvej'/> <tag k='kms:last_updated' v='2002'/> <tag k='kms:county_name' v='Sønderjyllands Amtskommune'/> <tag k='addr:street' v='Seggelund Hovedvej'/> <tag k='kms:municipality_name' v='Christiansfeld'/> This gets very messy, but I suppose tags could be trimmed on reading if there is some way to know/declare that they won't be used. The problem is then the relation matching can't use those, and this could get mysterious. I wonder if the style file could have a section to declare node tags to trim, and then abort if they are later used in styles? -------------- next part -------------- A non-text attachment was scrubbed...
