Description Pedro Ferreira 2016-02-17 12:45:07 UTC

As discussed on IRC.

KDevelop hung after I changed the include directories of 4 opened projects. I attached to the running process with GDB and produced the attached backtrace (https://paste.kde.org/pk4ewxxiv).

Several questions were asked on IRC about this.
For the seesion I had opened (4 projects), the configuration on the sessionrc file says
"Number of Threads=8"
"$ nproc" says 8.

I have a core dump for this lying around if further information required.

Reproducible: Didn't try

Comment 3 Sven Brauch 2016-07-26 11:35:26 UTC

I'm not exactly sure about the circumstances leading to this crash, but one thing that is definitely very bad is that AdaptSignatureAction::execute() calls waitForUpdate from the foreground. That needs to be changed.

Similarly, clang has a few places where it acquires a duchain lock in the foreground without a timeout. The parse job constructor is such a place. I think that is a very bad idea as well.
