Questions that were answered [edit section]

• How does a job get the result of "unstable" or "aborted", in the Jenkins interface?
  • the job result has to be changed by some entity. Jenkins does not detect 'unstable' itself.
    • 'unstable' is intended to reflect a build that maybe only partially completed. Something went wrong somewhere, but the build results may still be usable.
• what is postbuild.groovy used for in Fuego 1.0?
  • It was used to set the job description in the build.xml file
  • Benchmark.dbench failed on 5/13/16 due to postbuild.groovy problem
• how can I easily make a change in fuego inside the container (say to a test script), and then push it to my fuego-core repository outside the container?
• should I write a script to set up my own tools to work in the container?
  • yes - see ~/work/fuego/setup-container-git.sh

• how does ovgen.py work?
  • see Overlay Generation

• how does Jenkins know whether a fuego test succeeded or failed
  • See Feugo test results determination

• what does the notepad icon mean in the 0.History tab on the home dashboard screen?
  • It means that the test run has a build.description, and the notepad is a link to that.
  • This view is a "Latest tests run" portlet, provided by the Dashboard-view plugin, with the 0.History pane configured by Cogent Embedded.
  • See: Dashboard_view#the_0.History_notepad_icon_mystery for details

• how does Jenkins know the path to the jobs directory under /home/jenkins/fuego jobs?
  • there's a symlink from /var/lib/jenkins/jobs to /home/jenkins/fuego/jobs
  • Jenkins creates the build.xml file, and the symlinks for the build number, and last*Build files
  • see also: build.xml

• what plugins are installed in Jenkins in fuego, and what are they used for.
  • see Jenkins Plugins

• How can you see the devlog, systemlog and test log for a test?
  • If you go to http://localhost:8080/fuego/userContent you can see the directories that are in /var/lib/jenkins/userContent. This include fuego.logs, which is a symlink to /home/jenkins/logs

Questions answered, but not documented elsewhere in the wiki yet [edit section]

• why is the log not copied for Functional.hello_world.log (on test failure on Sep 1)
  • because the test program itself returned failure. It should only indicate failure in the log, and return success
    • or, the test script should force success after the test runs
  • FIXTHIS - document that test programs should exit with 0 indicating a successful run, even if what they are testing failed. Exit of non-zero indicates a failure of test infrastructure, not failure of the test.
