Bug report #8543

QgsVectorLayerEditBuffer.addedFeatures() function binding on Windows 8 causes crash

Added by Larry Shaffer over 9 years ago. Updated over 6 years ago.

Category:Python plugins
Affected QGIS version:master Regression?:No
Operating System: Easy fix?:No
Pull Request or Patch supplied:No Resolution:worksforme
Crashes QGIS or corrupts data:Yes Copied to github as #:17294


Repeatable steps:

  1. Put a vector layer into edit mode
  2. Add a feature
  3. Run commands in console
    eb = iface.activeLayer().editBuffer()
  4. Crash

QgsVectorLayerEditBuffer.addedFeatures() works fine on Mac (10.7.5, latest master), returning a dict.

Will try to get, or inspect, a crash dump soon.

Hi Larry,
this should not be hard to solve, I haven't a build environment under windows.

Anyone could try the following patch:

Hi Salvatore,

Not sure how that signal relates to the QgsVectorLayerEditBuffer.addedFeatures() public function.

Also, wouldn't changing that in the .sip file probably cause a build error when sip doesn't find a matching signature in the header file (qgsvectorlayereditbuffer.h)?

sorry for the overzealous approach, forget my note!

#4 Updated by Jürgen Fischer over 6 years ago

  • Crashes QGIS or corrupts data changed from No to Yes
  • Resolution set to worksforme
  • Status changed from Open to Closed

works fine for me (on windows 10 x86 and x86_64)
