Bug ID: 434031
Summary: Code parsing stalls (and hogs cpu) on
clang_parseTranslationUnit2 error
Product: kdevelop
Version: 5.6.2
Platform: Debian testing
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Language Support: CPP (Clang-based)
Assignee: kdevelop-bugs-n...@kde.org
Reporter: rasas...@gmail.com
Target Milestone: ---
Created attachment 136415
--> https://bugs.kde.org/attachment.cgi?id=136415&action=edit
all threads backtrace after 99% parsing and ctrl-Q kdevelop
When kdevelope is parsing a somewhat big project, with includes properly
configured so all code dependencies are captured, clang parser shows an error,
the background parser never ends parsing (stalled at 99%). Moreover on kdevelop
quit (ctrl-Q) the background parser keeps on running hogging the CPU
STEPS TO REPRODUCE
1. Start with a recent zephyr project checkout:
https://docs.zephyrproject.org/latest/getting_started/index.html (up to west
init step)
2. Open zephyr rtos recent version as project (CMake based)
3. Add some important parsing paths in the project language parsing
configuration:
zephyrproject/modules/lib/mcumgr/mgmt/include
zephyrproject/modules/lib/mcumgr/smp/include
zephyrproject/modules/lib/tinycbor/include
zephyrproject/bootloader/mcuboot/boot/bootutil/include
zephyrproject/zephyr/include
zephyrproject/bootloader/mcuboot/boot/zephyr/include
4. Let kdevelop parse the code
OBSERVED RESULT
Background parsing stalls at 99% and exit kdevelop keeps background parser
running, even GUI has been shutdown. You'd need to kill kdevelop (again) for it
to exit.
EXPECTED RESULT
kdevelop properly parses code, tolerates parsing failures or at least stop
background parsing.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Debian testing
kdevelop 5.6.2
KDE Frameworks 5.78.0
Qt 5.15.2
ADDITIONAL INFORMATION
I'm attaching an all threads backtrace. See how there are 2 lengthy stacked
frames threads
