Subject: [MapServer-users] How to check if file is ready before loading with
 MAP file?
Message-ID: <b3ee4638-83dd-4945-8f75-dbcf44e12314@lrec.pt>

Hi List,

I have Mapserver running loading heavy Geotiffs files. I run a periodic 
background C script to make dynamic geotiffs files but sometimes the 
Geotiff files are not? ready (they are still in building process)? when 
Mapserver load it and stops displays maps.

In PHP I can check that with "md5_file" function? comparing the two 
files.? I'm considering if there is any trick to do it with MAP files 
using a command like: "IF geotiff file not exist or not ready load another"


Any ideas would be appreciated.

Best Regards,

Carlos

With MapScript that would be very easy

Hi Carlos,

If you want to go down the PHP MapScript way, as Jan mentioned, we 
already do similar checks as part of the PHPUnit tests ( 
https://github.com/MapServer/MapServer/tree/main/msautotest/php ). 
Specifically, we use PHPUnit's assertFileEquals() function to compare 2 
files ( see example at 
https://github.com/MapServer/MapServer/blob/main/msautotest/php/mapObjTest.php 
), and you can even check speeds (see example at 
https://github.com/MapServer/MapServer/blob/main/msautotest/php/reprojectionObjTest.php 
)

(if you're wondering, we use PHPUnit version 12, from https://phpunit.de/ )

Hope that helps,

-jeff

Subject: [MapServer-users] SLD styling : how to advertise for WMS/STYLE
 parameter
Message-ID: <CAAes_OH00iXuaYoCD1Lct3PM2njV-afGUfxSejpckHFV4q3HUA@mail.gmail.com>

Hi all,

In our WMS server, I would like to advertise two different styles :

   - 1st style based on mapfile definition : 'default'
   - 2nd style based on SLD definition : 'sldStyle'


I would like to offer clients a way to  select which style they want to
apply, using the WMS "STYLE" parameter :
http://localhost/qgisserverxxx?SERVICE=WMS&REQUEST=GetMap&STYLE=sldStyle

I have tried to use CLASSGROUP, NAME and GROUP keywords. My main file looks
like :
LAYER
   ...
   CLASSGROUP "MyVectors"
   ...
   # Mapfile definition
   CLASS
      NAME 'Name1'
      GROUP 'default'

      STYLE
         ...
      END
      LABEL
         ...
      END
   END # CLASS

   #SLD definition
   STYLEITEM "sld://SldDefinition.sld
END

My question is :
How do I declare different styling groups within SLD definition ? The CLASS
/ NAME keyword is not appropriate.

In the Mapserver documentation, I found two SLD keywords which could give a
style name :

   - <NamedLayer>/<NamedStyle>/<Name>
   - <NamedLayer>/<UserStyle>/<se:Name>

Which one should I use ?

<StyledLayerDescriptor version="1.1.0" ...>
   <NamedLayer>
      <se:Name>landsat</se:Name>
      <NamedStyle>
         <Name>sldStyle</Name> <====== this one ?
      </NamedStyle>
      <UserStyle>
         <se:Name>sldStyle</se:Name> <==== or this one ?
         <se:FeatureTypeStyle>
            ...
         </se:FeatureTypeStyle>
      </UserStyle>
   </NamedLayer>
</StyledLayerDescriptor>

Thanks for your help
Philippe
