Crashing WFS in 32bit Windows Install

Description

QGIS crashed when identifying or selecting certain features through a WFS connection. This seems to effect the windows 32 bit stand alone and OSGeo4W installs, installed on either a 32 bit or 64 bit computer.

So using the 64 bit install on a 64 bit computer works fine, but using the 32 bit install on a 64 bit or 32 bit computer causes an issue.

Tested on 2.0.1, and master through OSGeo4W.

Replication:
Add in a WFS, for example from the British Geological Survey:
http://ogc.bgs.ac.uk/cgi-bin/BGS_Bedrock_and_Superficial_Geology/wms?

Add in the layer:
UKContShelf BGS 1:1M Seabed Sediments

Open up the attribute table. Select feature number 99 and zoom to it, select any other feature, and re-select feature number 99. At this point my QGIS crashes, with the message "Crash dumped". This is not limited to the BGS WFS connection, however this is an open WFS so should be able to be tested by all.

I have attached a project file, which should open up the WFS and zoom to a feature that causes the crash.

Of note, if all of the features are selected (or a large number) then it does not, also the feature can be selected from the attribute table.

I would be happy to provide further information.

wfs: catch end of selected features (fixes #8979)

History

Status changed from Open to Feedback

I cannot replicate this issue, using both a normal Windows installation and a Virtual Machine.

Have you tested run qgis without loading plugins? Or just tested on another machine?

#2 Updated by Jukka Rahkonen about 11 years ago

Hi,

Same crash happens for me but a bit earlier. Load data from WFS, open attribute table, select one, zoom, close attribute table, select a neighbouring feature and crash, no need to select again the first selected feature. Tested with two WFS servers with polygon feature types. QGIS version 2.0.1 on 32-bit Windows Vista. QGIS installed with installer.

On Windows/QGIS 2.0.1 I'm struggling with WFS polygon layers (it usually says that the layer it is not valid), but it seems to work on master. Anyway I cannot replicate the issue. Have you tested run qgis with no plugins (--noplugins)?

#4 Updated by Jukka Rahkonen about 11 years ago

Sorry, but I do not know how to start QGIS with no plugins on Windows. I suppose I should edit something in the file C:\\Program Files\\QGIS Dufour\\bin\\qgis.bat

@echo off call "%~dp0\\o4w_env.bat" call "%OSGEO4W_ROOT%"\\apps\\grass\\grass-6.4.3\\etc\\env.bat @echo off path %PATH%;%OSGEO4W_ROOT%\\apps\\qgis\\bin;%OSGEO4W_ROOT%\\apps\\grass\\grass-6.4.3\\lib set QGIS_PREFIX_PATH=%OSGEO4W_ROOT:\\=/%/apps/qgis set GDAL_FILENAME_IS_UTF8=YES rem Set VSI cache to be used as buffer, see #6448 set VSI_CACHE=TRUE set VSI_CACHE_SIZE=1000000 start "QGIS" /B "%OSGEO4W_ROOT%"\\bin\\qgis-bin.exe %*

you can just modify the shortcut in your desktop/start menu. Or just disable/uninstall all plugins and restart qgis.

#6 Updated by Jukka Rahkonen about 11 years ago

Hi,

The shortcut points to that qgis.bat file I referred as
"C:\\Program Files\\QGIS Dufour\\bin\
ircmd.exe" exec hide C:\\PROGRA~1\\QGISDU~1\\bin\\qgis.bat
Anyway, I disabled all the plugins and behaviou is the same. You can see it from a video http://latuviitta.org/documents/QGIS_20_WFS_select_feature_crash.swf

This time I had to do "Select one feature" many times before crash happened, more often the second select is enough.

can you post the url of the server you are using?

#8 Updated by Jukka Rahkonen about 11 years ago

http://hip.latuviitta.org/cgi-bin/tinyows

I used the feature type "municipalities". It is my own server and I know from the logs that QGIS does not discuss with WFS when the crash happens. It has done the GetFeature and continues then with cached data.

confirmed with this server/layer, and does not happen on qgis 1.8
