Bug ID: 448684
Summary: KDevelop process does not terminate.
Product: kdevelop
Version: 5.7.211201
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: general
Assignee: kdevelop-bugs-n...@kde.org
Reporter: lemuelsimo...@protonmail.com
Target Milestone: ---
SUMMARY
Upon quitting KDevelop normally (Alt+F4 or closing the window), the window
closes, but a `kdevelop` process is left in the background. The process would
hog a single thread/CPU core with 100% usage, and it doesn't go away. No errors
are thrown and no crashes occur. This is reproducible on every launch and exit
of KDevelop. Clearing `~/.cache/kdevduchain` or `~.cache/kdevelop` doesn't
change the outcome. Running it with `strace` doesn't show anything useful and
running it in the console doesn't show anything either.
STEPS TO REPRODUCE
1. Launch KDevelop
2. Quit KDevelop (doesn't matter if a session is chosen or not).
OBSERVED RESULT
KDevelop doesn't terminate and must be forcefully killed with 'kill -9'. The
process hogs the CPU thread or core and upon relaunch (if the process is still
active), the new KDevelop instance would complain about a session already being
active.
EXPECTED RESULT
KDevelop's processes terminate normally. No zombie or background processes left
behind.
ADDITIONAL INFORMATION:
I would like to think this was a regression, as this problem didn't occur in
previous versions (IIRC). I do not recall having this problem two months ago.
