Description

Using the current master branch (rev 20c729a), QGis crashes when enabling labelling on some layers. To reproduce:

Open the properties of a layer.
In tab "Labels", select "Label this layer with", select a field.
Validate the dialog.

This is the debug output given by QGis after validating:

#1 Updated by Larry Shaffer over 11 years ago

Hi Laurent,

It looks like the function that may be causing the issue, QgsGeometry::exportWkbToGeos(), was worked on recently to fix a bug in commit 0594453 ("on github":commit:0594453ff55e705854e0cf00de72e3feadbf6c14#src/core/qgsgeometry.cpp). While it looks to be unrelated to labeling, I am leaving issue classified under labeling because it is where the new issue presents itself.

Can you, in any way, verify when you last had a working project? Can you possibly build and test a version of master branch prior to the above mentioned commit? Or can you try with latest master to just revert that commit, using git, and do a test build?

Hi Marco,

I am assigning this issue to you because I think it may be related to a recent commit of yours. Please undo the assignment if I am incorrect.

#3 Updated by Laurent Defert over 11 years ago

Hi, thanks for your fast response.
I tried reverting the commit 0594453 with no luck.
I cannot find which commit introduced the regression, as I was previously using the 1.8 version and switched to git (I was impacted by #6473).

After further investigation, I found that it gets triggered when the data are loaded from a WFS server. Creating the layer from a PostGis tble then labelling the same dataset doesn't crash.

I found a public WFS server with which I was able to reproduce the bug, here are the steps:

Start QGis with a new project
Add the WFS server http://giswebservices.massgis.state.ma.us/geoserver/wfs
Create a layer using the table "Multi-use Area (ocean management)"
Enable labels as described initially in the ticket.

Priority changed from Severe/Regression to Normal
Category changed from Labelling to Vectors

Hi Laurent,

Well, this is unrelated to labeling as far a I can tell. Loading the layer you mentioned and trying to do anything that validates the geometry either crashes the app or uses up all RAM.

Load WFS layer mentioned above (Save as... to new, local vector format, makes no difference)
Open Vector->Geometry Tools->Check geometry validity
Select WFS (or the same layer saved to another vector format)
Validate geometry quickly leads to QGIS eating up ALL available RAM. In my case 7.5 GB in 3 seconds. Stopping validation does not reclaim RAM. Quitting does.

OR...

Load WFS layer mentioned above
Save as... to new, local vector format and load saved layer
Put new layer into edit mode
Select node tool and click on geometry(it's one feature, whose geometry is 'validated')
Validate geometry quickly leads to QGIS eating up ALL available RAM (as above). Usually resulting in crash.

OR...

Load WFS layer mentioned above
Try to select the feature leads to same issue as above

Basically, the geometry is rendered, but many functions that try to work with it cause the symptoms noted above. I think the geometry for that layer needs fixed in some way before it can be used in QGIS.

Do you have another data source that exhibits the issue?

I also tried to split the multipart geometry into single parts, but ended up with no features in the resultant file.

I've set the issue priority to 'normal' until such time as it can be verified that it is not just very bad/funky geometry.

Hi,
I'm having this issue on an other WFS server (one I'm currently writing), and the particular geometry that triggers this behaviour works well when it's loaded from a PostGis database, so I'm starting to think the problem may be in the WFS client or ogc parsing. I'll tell you if I can find more.

Well, I'm a bit puzzled about this issue, neither the WFS code or the QgsGeometry related methods have changed since 1.8.. It looks like a weird side-effect.. Tell me if you have some clue, or if I can provide more testing.
Thanks
