TOLERANCEUNITS problem

We did notice the issue with the default value of TOLERANCE. We decided
to update the documentation for 4.4 rather than change the value. Didn't
want to break 4.x apps. I'm not aware of any issues with tolerance
units. The query code itself has been very stable for a good while now.
The default tolerance unit is PIXELs. If you have an example mapfile and
test case that would help. I'd try 4.4 first to see if that makes like
better.

Hi List,

I have a problem querying with mapserver 4.2 CGI. The problem did not
exist
in 3.6.

To query a point, I must have the 'TOLERANCE' set in my layer despite
the
documentation declaring that there is a default value of 3 pixels. I
recall
mapserver 3.6 using the default value correctly without having to place
the
tolerance in the layer.

The 'TOLERANCEUNITS' setting is having no effect at all, acting as if
it is
permanently set to kilometers ... no matter for my overview scale map,
but
a real pain for my local zoomed in maps.

The problem seems to happen with points, lines or polygons.

Any suggestions? Has this been noticed and fixed in 4.4?

Thanks,
Ken Lord
