Summary: eventloop lockup in GitPlugin::getLsFiles when
deleting whole project folder opened in kdev
Product: kdevplatform
Version: SVN
Platform: Unlisted Binaries
OS/Version: Linux
Status: NEW
Severity: major
Priority: NOR
Component: git
AssignedTo: kdevelop-bugs@kdevelop.org
ReportedBy: mail@milianw.de
Version: SVN
OS: Linux
I think this should be reproducible (no time for that right now). Seems like
the git jobs cannot cope with the folder to work on being removed completely.
Reproducible: Didn't try
Steps to Reproduce:
- had a sub folder of a project in kdevelop open as top-level project, it was
git-tracked
- git pulled, the sub folder was removed, hence the project in kdevelop was
empty
- I wanted to close it, hence requested ctx menu
=> lockup
