Debugging

My lbs.solidcharity.com server is the development server at the same time. That way I can test the new code immediately.

It runs an installation installed from RPM.

I use the makeinstall.sh script to copy the code from my git directory to the live installation, and restart uwsgi.

I can see most errors in journalctl -f.

Sometimes it is easier to run lbs.py directly, to see errors on the command line. This is what I do:

systemctl stop nginx
systemctl stop lbs
cd mygitdirectory/web
./lbs.py
# now I can see the requests coming in, stack traces, print() output etc
# attention: for builds to start, visit the machines page in the webbrowser
# after the test:
chown -R lbs:lbs /var/lib/lightbuildserver/src
chown -R lbs:lbs /var/lib/lightbuildserver/tarballs
chown -R lbs:lbs /var/lib/lightbuildserver/repos
chown -R lbs:lbs /var/lib/lightbuildserver/logs
chown -R lbs:lbs /var/lib/lightbuildserver/db
cd ..
systemctl start nginx
systemctl start lbs
./makeinstall.sh

To check the the database:

sqlite3 /var/lib/lightbuildserver/db/lightbuildserver.db
   select id, name, status, buildjob, queue, username, projectname, packagename from machine;
   select id, status, username, projectname, packagename, branchname, distro, release, arch, dependsOnOtherProjects, buildmachine, started, finished, buildsuccess, buildnumber from build limit 20;
   select id, status, buildmachine, started, finished, hanging, buildsuccess, buildnumber from build where status <> 'FINISHED' and status <> 'CANCELLED' limit 20;

see the database structure: https://github.com/SolidCharity/LightBuildServer/blob/master/lib/LightBuildServer.py#L49

To initiate the build, you need to visit the page /machines, which will trigger builds from the job queue.
