[mapserver-dev] MapServer 5.2 Beta 3 Available

[Jim Klassen]

Paul,
 
This patch does fix the error for me.
Jim
 
BTW: we use relative paths because it provides a lot more flexibility in being able to change the server config and/or move our apps to another server without having to update hundreds of map files.

Paul,

    I'm under the impression the discussion is about raster tileindexes, 
not shapefile tileindexes.  I'm more ignorant about the latter, and its 
patch was riskier and more invasive, so I have no problem with whatever 
compromises have to be made with the shapefile tileindexes patch 
(including not merging for 5.2).

    With raster tileindexes however, I think the changes are realistic; 
I attached a two-line patch to 
http://trac.osgeo.org/mapserver/ticket/2369 (also attached here).

     Jim, does the attached patch fix the Image handling error for you?

Thanks,

Dave
