Description

ttcn3 jenkins jobs fail if the tested component crashes with a core dump.

The issue is that docker runs (for example) osmo-msc as root and if it crashes the core dump generated is also owned by root - but without read permissions for others. Then the jenkins task that collects the artifacts runs as user and fails to read the core file. The log file is also owned by root, but since it is readable by all it can be archived.

The workspace of osmo-msc-test shows the core file and also shows that it can't be read by jenkins.

One possibility would be to run osmo-msc inside docker as user instead of root, but then you need to ensure that uid inside and outside of docker match. Fixuid seems to do exactly that: https://github.com/boxboat/fixuid

We could just sudo chown -R $USER $VOL_BASE_DIR in jenkins.sh or in the jenkins job after running jenkins.sh if we don't want to have it in the script.

I'm calling docker with chown since some other ideas (suid binary) didn't really seem to work as expected

Patch is in Gerrit:

It seems that ttcn3-msc-test-latest needs some care before it can run again:
https://jenkins.osmocom.org/jenkins/view/TTCN3/job/ttcn3-msc-test-latest/

The above patch should also fix such issues in the future.

I've manually removed the files and re-triggered a build.

The above patch should also fix such issues in the future.

The patch should be merged now, thanks.

Should be resolved now, though osmo-msc doesn't seem to crash anymore.
