Bug report #8475

Program crashes when .sld is applied

Added by John Scott about 6 years ago. Updated about 6 years ago.

Status:Closed
Priority:Severe/Regression
Assignee:-
Category:Symbology
Affected QGIS version:master Regression?:No
Operating System: Easy fix?:No
Pull Request or Patch supplied:No Resolution:
Crashes QGIS or corrupts data:Yes Copied to github as #:17243

Description

I have tried this in both Windows and Ubuntu
Version 1.9.0
After opening a shapefile I wanted to apply a .sld file
In the Layer Properties I click Load Style, the dialog box opens and I navigate to the .sld file location.
Choose the file and click open

In the Ubuntu version the program just closes.
In windows it produces a .dmp file (see attached)

I apologize....the .dmp file is 40+ mb and would not attach

#4 Updated by Salvatore Larosa about 6 years ago

the debug message before the crash is:

src/core/symbology-ng/qgsrulebasedrendererv2.cpp: 547: (createFromSld) parser error: unable to convert 'Filter' element to a valid 
expression: it is not supported yet or it has invalid arguments

Please provide some dataset to reproduce this bug.

Thanks in advance

it crashes using any dataset, I guess !

is it working fine for you ?

#7 Updated by Daniel Vaz about 6 years ago

As described in http://www.mapserver.org/development/bugs.html :

The most important thing when reporting a bug is to boil down a minimum example that is needed to reproduce the bug.
The chances of a bug being addressed in a timely manner is directly related to the speed with which the developer can reproduce the bug.
If you make that hard for the developer, chances are the bug will be given up on or ignored for quite a while.

Maybe it is a good idea to put this consideration at the top of "New issue" page.

As you said, maybe this bug causes crash with any dataset. But if I have the shapefile, the .sld file and the expected behaviour in applying this specific .sld on a specific shapefile the process could be faster.

Thanks in advance

#8 Updated by Giovanni Manghi about 6 years ago

Hi Daniel,

load a vector (I tested shapes and postgis) and make any categorized symbology and save it as sld. Then load the sld style. It crashes all the times here.

#9 Updated by Salvatore Larosa about 6 years ago

I managed to track out the issue, the SLD may be loaded and the crash disappear after commenting out the following line:

if ( mCalc )
    delete mCalc;

in QgsExpression destructor (src/core/qgsexpression.cpp). That piece of code was introduced in a261812, so I think this is an easy issue to solve for Jürgen.

Anyway, I noticed another issue here, it seems the SLD has not written correctly:
If a filter is applied the keyword <ogc:Filter> is duplicate, that throws the error reported to the comment nr.4

SLD created by QGIS:

<ogc:Filter>
 <ogc:Filter>
  <ogc:PropertyIsEqualTo>
   <ogc:PropertyName>boroname</ogc:PropertyName>
   <ogc:Literal>Brooklyn</ogc:Literal>
  </ogc:PropertyIsEqualTo>
 </ogc:Filter>
</ogc:Filter>
