Qgis Desktop cannot open layers from Qgis Server if the short_name option has been setup

Original Redmine Issue: 15482
Affected QGIS version: 2.14.5
Redmine category:qgis_server
Assignee: René-Luc ReLuc

---

How to replicate:

• use the short_name option for a layer
• serve that layer trough QGIS Server
• when trying to add it with Qgis Desktop it throws an error:

Invalid Layer: WMS provider Cannot calculate extent (file: src/providers/wms/qgswmsprovider.cpp row: 137function QgsWmsProvider:) Raster layer Provider is not valid (provider: wms, URI: contextualWMSLegend=0&crs=EPSG:3844&dpiMode=7&featureCount=10&format=image/jpeg&layers=adr&styles=&url=http://qgisplatform.demo/cgi-bin/qgis_mapserv.fcgi?map%3D/home/web/Downloads/proiect_qgis/harta.qgs%26VERSION%3D1.3.0%26 (file: src/core/raster/qgsrasterlayer.cpp row: 668function setDataProvider:)

If I do a getmap request in a browser it works well.

Tested under 2.16 and 2.14

It seems that even if I rename to whatever any layer in any qgs project I cannot add that layer in QGIS Desktop (same error message).

I just found a workaround: delete the .qgis2/cache directory.
However, we shouldn't be in this case.

this has been reported several times lately (we should try merge all these reports): even with the cache set to 0 in general options the wms client fails to load layers from qgis server services that have been changed. Forcing to clean cache (from GUI or manually as you did) solves the issue, but as you said this should not happen and was not a issue in the past.

Seen also on other platforms.

Hi Tudor and René-Luc, what is the status of this issue in the latest point releases of qgis server 2.14 and 2.18?

@giovanni The issue is not reproducible anymore. I tested under 2.14 and 2.18 and everything is working as it should.
