Git commit a723b77167b8d5aad7c9f6a5728a0633967a1f1a by Sven Brauch. Committed on 02/12/2014 at 12:43. Pushed by brauch into branch '1.7'. Fix crash when building completion items for functions with no arguments context I'm not sure how this situation can happen, but the referenced bug describes code which triggers the issue. This commit just fixes the crash which happens in that case.

I'm not entirely sure how the bug is triggered, but this fixes it for now. Thank you so much for the quick fix! I can confirm that it working fine now. Long live kdev-python! Thanks, cool :-) |
If I have a file that imports "viewsets" from django-rest-frameworks project, kdevelop crashes while trying to type new method, i.e. "def a..", in any class that extends classes from "viewsets" file. See reproduction steps below for details. kdevelop version 4.7.0 kdev-python version 1.7.0; also tried compiling git master python version 2.7.6 Reproducible: Always Steps to Reproduce: 1. cd /tmp/ 2. virtualenv dead 3. source /tmp/dead/bin/activate 4. mkdir /tmp/dead-code 5. cd /tmp/dead-code 6. pip install Django==1.7.1 djangorestframework==3.0.0 7. PYTHONPATH=/tmp/dead/lib/python2.7/site-packages kdevelop -n dead 8. import /tmp/dead-code directory as a project into kdevelop 9. create new file "dead.py" with the following contents: from rest_framework import viewsets class MyViewSet(viewsets.ModelViewSet): 10. Wait until everything gets parsed and "viewsets.ModelViewSet" in class definition becomes green. 11. Start new line after class definition and start typing "def a". Once you type "a", kdevelop will crash. I.e. dead.py would be looking as follows: from rest_framework import viewsets class MyViewSet(viewsets.ModelViewSet): def a ============= If you relaunch kdevelop and tell him to recover the file, it will crash again. Here is the console log with debug enabled after I've started to type "def a": kdevelop(1176)/kdevplatform (language) KDevelop::StaticAssistantsManager::Private::eventuallyStartAssistant: Trying to find assistants for language "Python" kdevelop(1176)/kdevplatform (genericprojectmanager) KDevelop::AbstractFileManagerPlugin::Private::created: created: "/tmp/dead-code/.dead.py.kate-swp" kdevelop(1176)/kdevplatform (language) KDevelop::StaticAssistantsManager::Private::eventuallyStartAssistant: Trying to find assistants for language "Python" kdevelop(1176)/kdevplatform (language) KDevelop::CodeCompletionModel::completionInvokedInternal: completion invoked for context 0x4fdf0a0 kdevelop(1176)/kdevplatform (language) KDevelop::CodeCompletionModel::completionInvokedInternal: Found context is not current.
