[mapserver-users] Shapefile indices and Mapserv vs Mapscript

[Stephen Woodbridge]

Sean,

The msSearchDiskTree() error is only informational. It means that some
of your shapefiles do not have spatial indexes built for them (ie: not
all *.shp have a *.qix file. You can suppress the message in mapscript
by putting an '@' in front of the call to draw the map, or build the
indexes using shptree. Mapserver has probably been built with ignore
missing data option so it ignores this fact. the error report by
mapscript is from the mapscript wrapper and not mapserver. So that
should explain the difference. I have written a bug/enhance request to
include the file name that is generating the error to make it easier to
chase these down.
