Hi,<br>
<br>
I am using the query below to return a hydrograph of a region (using<br>
POSTGIS). This query works perfectly when I use it in pgadmin. With the<br>
mapserver, the connection with the client is lost. It records a query that<br>
shows no errors in SQL, just shows that the connection has lost. Why is<br>
that?<br>
<br>
DATA "geom FROM (<br>
SELECT<br>
hidro.fid, <a href="http://hidro.name" rel="noreferrer" target="_blank">hidro.name</a>, ST_Intersection(gcc.geom, hidro.geom) AS<br>
geom<br>
FROM<br>
vector.hidrography AS hidro,<br>
vector.gcc AS gcc<br>
WHERE ST_Intersects(gcc.geom, hidro.geom) AND <a href="http://gcc.name" rel="noreferrer" target="_blank">gcc.name</a> = 'GRANDE'<br>
) as subquery USING UNIQUE fid USING SRID=4326"<br>
<br>
Thanks in advance<br>
<br>

Hi,<br>
<br>
What client are you using?<br>
How long does the query take to complete?<br>
It is likely the client stops waiting for a response.<br>

Hi Fernando,<br>
<br>
I would try using the shp2img utility at the commandline, and set CONFIG <br>
"CPL_DEBUG" "ON" in your mapfile (see <br>
<a href="https://mapserver.org/optimization/debugging.html#step-3-turn-on-cpl-debug-optional" rel="noreferrer" target="_blank">https://mapserver.org/optimization/debugging.html#step-3-turn-on-cpl-debug-optional</a>) <br>
and then execute:<br>
<br>
shp2img -m mymap.map -o ttt.png -all_debug 5<br>
<br>
The full query should be listed there in the response, which you can <br>
then paste into the psql commandline, and manually execute the same <br>
query to your database.<br>
<br>
PS. hello to my friends in Brasil!<br>

Hi,<br>
<br>
This issue is related to:<br>
<br>
* <a href="https://github.com/mapserver/mapserver/commit/722716c49de2399f54b275ab31437f0e8c92cd63" rel="noreferrer" target="_blank">https://github.com/mapserver/mapserver/commit/722716c49de2399f54b275ab31437f0e8c92cd63</a><br>

<br>
The issue is that when I try to visualize (via WMS) a layer with a NetCDF data file with longitude from 0° to 360° in EPSG:3857, there is a sliver around longitude 0° where no data is displayed.<br>
<br>
We already had that issue with the same files using EPSG:4326 and it's been fixed in MapServer (see merge request above).<br>
<br>
Here is where you can find example files: <a href="https://dd.weather.gc.ca/model_giops/netcdf/lat_lon/2d/00/003/CMC_giops_votemper_depth_0.5_latlon0.2x0.2_3h-mean_%7Byyyymmdd%7D00_P003.nc" rel="noreferrer" target="_blank">https://dd.weather.gc.ca/model_giops/netcdf/lat_lon/2d/00/003/CMC_giops_votemper_depth_0.5_latlon0.2x0.2_3h-mean_{yyyymmdd}00_P003.nc</a><br>
<br>
We are testing using: MapServer version 7.4.4 OUTPUT=PNG OUTPUT=JPEG OUTPUT=KML SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=CAIRO SUPPORTS=SVG_SYMBOLS SUPPORTS=RSVG SUPPORTS=ICONV SUPPORTS=FRIBIDI SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER SUPPORTS=SOS_SERVER SUPPORTS=FASTCGI SUPPORTS=THREADS SUPPORTS=GEOS SUPPORTS=POINT_Z_M INPUT=JPEG INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE<br>

Hi,<br>
<br>
I am reviving a Python 2 MapServer MapScript app that used to work 7 <br>
years ago (and still is in old deployment) but stuck in some MapScript <br>
calls that fail but also throw no Exceptions.<br>
<br>
Purpose of the app "MapGlow" [1] is to generate a WMS-heatmap triggered <br>
by specific STYLE parameters. When no heatmap STYLE is requested <br>
requests are delegated to map_file.OWSDispatch() etc. The latter works <br>
fine so the overall setup/stack/mapfile is working. Using MS 7.6.0 in <br>
Docker (compose) with Lighttp, FastCGI, WSGI, flup.<br>
<br>
It is only when layerObj.queryByRect() is called, a HTTP 500 is <br>
returned after a FastCGI hard error, no means to catch an Exception. The <br>
passed MapFile and Rect objects seem ok. Also I noticed that <br>
layerObj.metadata had 0 items. I can see that I have proper SWIG objects <br>
like<br>
<mapscript.layerObj; proxy of <Swig Object of type 'layerObj *' at <br>
0x7fded06b1de0> ><br>
If only I could get a hint, a MapFile setting, maybe some log output or <br>
debug flag I can set? The WIP is on GH, I can point at the failing line <br>
[2] but the code is<br>
quite involved (mind, my first Python 7-9 years ago):<br>
