Bug ID: 398822
Summary: Segfault when folders are added with a cmake option in
cmakepreferences
Product: kdevelop
Version: unspecified
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kdevelop-bugs-n...@kde.org
Reporter: k.h...@gmx.de
Target Milestone: ---
Application: kdevelop (5.3.40)
(Compiled from sources)
Qt Version: 5.11.1
Frameworks Version: 5.50.0
Operating System: Linux 4.15.0-33-generic x86_64
Distribution: KDE neon User Edition 5.13
-- Information about the crash:
- What I was doing when the application crashed:
1. Project -> Prune Selection
2. Project -> Configure Selection
3. Project -> Open Configuration...
4. Enable custon "test" cmake option
5. Click on OK -> segfault
I used this CMakeLists.txt
==================
cmake_minimum_required(VERSION 3.5)
project(crash)
option(test "build tests" OFF)
add_library(crash
source/lib.cpp
)
if(test)
add_executable(unittest test/test.cpp)
target_link_libraries(unittest PRIVATE crash pthread)
endif(test)
==================
source/lib.cpp
==================
int add(int a, int b) {
return a + b;
}
==================
test/test.cpp
==================
int main() {
return 0;
}
==================
It seems some ProjectFolderItems are created and added to the queue in
FileManagerListJob. Then all ProjectFolderItem are deleted and when the next
FileManagerListJob::startNextJob() accesses an element in the queue it's a
dangling pointer and segfaults.
I could track the issue to AbstractFileManagerPlugin::import. The KDirWatch
item is still connected to the project path. When CMakePreferences::configure()
triggers a reload, the KDirWatch triggers FileManagerListJob::startNextJob()
but the ProjectFolderItems are also deleted.
I could fix the problem by diconnecting all slots from KDirWatch for the given
project, they are connected anyway when reloadModel triggers an import.
I did this from CMakePreferences::configure() through the varius abstraction
layers up to AbstractFileManagerPlugin. Don't know if this is a viable
solution. Someone with more insight has to make a proper fix.
The crash can be reproduced every time.
