Bug ID: 372040
Summary: KDevelop editor become unresponsive when clicking into
a problem
Product: kdevelop
Version: git master
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Language Support: CPP (Clang-based)

perf record output
If I click on an underlined identifier, the editor becomes unresponsive for
several seconds. I noticed that when I navigate to the identifier in the editor
using keyboard arrows, there is no slowdown and KDevelop is perfectly
resnposive the whole time.
This problem happens with a work-related project that can be considered
somewhat peculiar. There are about 6000 includes in ~500 subdirectories in the
include path. The project itself is only a small subset of sources - the
problem occurs even with a small test project that consists only of a single
file that includes only few of the includes, though it becomes worse with
larger projects. The sources are mounted using samba from a locally running
virtual machine.
Attached is a profile generated using the linux perf utility with the following
command:
perf record -g -p <PID> sleep 3
which I executed just before clicking on a problem in the editor.
