Bug ID: 465626
Summary: Memory Leak with calls to Application.documents() in
Python
Classification: Applications
Product: krita
Version: nightly build (please specify the git hash!)
Platform: Appimage
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Scripting
Assignee: krita-bugs-n...@kde.org
Reporter: monoba...@hotmail.com
Target Milestone: ---
SUMMARY
Krita memory usage increases with each call to Application.documents(), or
Krita.instance().documents(), or ki.documents() where ki = Krita.instance().
STEPS TO REPRODUCE
1. Have some images open in Krita.
2. Open Scripter.
3. Paste and Run the following:
ki = Krita.instance()
for i in range(0, 50000):
ki.documents()
OBSERVED RESULT
Approximate change in krita memory usage as shown by system monitor:
images open - total change - change per call (total change/50000)
0 images - 0mb - 0mb
1 image - 22mb - 0.45kb
8 images - 150-200mb - 3.1-4.1kb
16 images - 335mb - 6.86kb
EXPECTED RESULT
no change in memory usage.
SOFTWARE/OS VERSIONS

ADDITIONAL INFORMATION
- Assigning ki.documents() to variable, setting variable to None, doing del on
variable - make no difference.
