[mapserver-users] crash on SYMBOL

Hi list, we have some faulty MAP files, which did not crash MS 5.2, however they do seem to crash MS trunk. It results in a segfault (e.g. in a WMS GetCapabilities request) when we use e.g. SYMBOL 604310017 Any idea what has changed in the meantime to cause this to segfault? TIA. Best

[mapserver-users] long-running postgres queries initiated by mapserver

Hi All- I'm running mapserver 5.6.3 under centos 5.4, using fastcgi. I'm using postgres as the data storage container, and mapserver is primarily serving WFS requests. Sometimes, people do WFS queries that take a very long time (searching for virginia on a nation-wide layer) and eventually

Re: [mapserver-users] long-running postgres queries initiated by mapserver

Matt, I suggest to enhance the PostgreSQL performance at first. Each table with geometry must have a GiST spatial index. When you upload a shape file to PostgreSQL, the shp2pgsql creates this index specifying the -I parameter. Have you uploaded your data in this way ? If the geometry have

[mapserver-users] White lines when reprojecting aerial photo

Dont know if this relates to your problem, but its easy to check.  We normally  use the GD/JPEG driver when doing image data.  My understanding is that AGG is more useful for outputting vectors to PNG. Also, this will slow it down but in the raster layer PROCESSING RESAMPLE=BICUBIC rather than

Carlos, Thank you for your response, and indeed the tables do have indices. The spatial search is just fine and comes back very quickly, however the text-based searches do not come back quickly (propertyIsLike for example). I suppose I wasn't clear enough in my original question. Mapserver

Re: [mapserver-users] long-running postgres queries initiated by mapserver

Your welcome, Matt. Now it is clear why the query is slow. You must have indices on the columns that you're searching in (and run VACUUM frecuently to keep them updated). If you're using LIKE operator, then the indices are not useful if the columns are not LOCALEd. Check if you have defined

Re: [mapserver-users] White lines when reprojecting aerial photo

Also, this will slow it down but in the raster layer PROCESSING RESAMPLE=BICUBIC rather than default NEAREST is effective especially for hi-rez data. Thanks a lot Mark, I totally forgot on resampling methods. I have tried BICUBIC which doesn't work, but BILINEAR is working fine. Ivan

Re: [mapserver-users] crash on SYMBOL

Bart, Is 604310017 a symbol name? If you add quotes around it in the mapfile then the entry should be treated as a symbol name and the seg fault would go away, can you verify that? I suspect the integer value 604310017 (without quotes) is treated as an index and used to access the array of
