Description
Sometimes Ubuntu 24.04 x64 targets:
- ubuntu-24.04-x64-x11-tests
- ubuntu-24.04-x64-developer-build-x11-tests
have failed with 200, 500 or even 600 failing tests with QDEBUG prints flooding in 60,000 - 80,000 lines.
Not sure are those prints causing more failings, or just a symptom of something else. They are of course visible because test has failed, but with this amount of tests failing, it might be worth to investigate could this flooding of qdebug prints be connected to the rootcause, and possibly suppress qdebug prints temporarily to test could it decrease the amount of failings with Ubuntu 24.04 x64 or not.
Prints are from deleteLater -functionality:
Issue visible i.e. here:
- Target: ubuntu-24.04-x64-developer-build-x11-tests 331 fails
- Tests: https://testresults.qt.io/coin/integration/qt/qt5/tasks/nightly1733694301
- qtbase tests:
-
- 1047 QDEBUG prints flooding

- CI metrics for those testresults:
I.e. lots of "Increased/Decreased" "scope level to" is visible:

Found similar amount of failings from Ubuntu 22.04 target:
- Target: ubuntu-22.04-developer-build-x11-tests with 615 failings
- CI metrics: https://testresults.qt.io/grafana/d/ce11sn92oenswe/ci-metrics-e28093-ci-testresults?orgId=1&var-testresult_id=nightly1732657502&var-platform=ubuntu-22.04-developer-build-x11-tests&from=now-30d&to=now
- Testresults: https://testresults.qt.io/coin/integration/qt/qt5/tasks/nightly1732657502
More comparable tests with same failings when target has multiple tests failing:
