Fuego Jamboree 2

Introduction [edit section]

The Fuego Jamboree is a technical meeting of Fuego Test System development community. We plan to hold these meetings on a regular basis, to share ideas and plan new features and improvements for the Fuego Test System. We are having our second Fuego Jamboree, coming up in June, 2018!

Notes for discussion of Roadmap and Priorities [edit section]

Place notes here during or after the meeting Thanks to everyone who came to the event. It was valuable having you there!

Here are a few notes that Tim took from the meeting:

ftc run-test issues [edit section]

  • Daniel proposed isolating Jenkins code in ftc, so that commands that don't need to access Jenkins don't have dependencies on it (e.g. don't do 'import jenkins' unless needed)
  • Khiem noted that there may be concurrency issues using the command line tool only
    • Jenkins handles job concurrency if the job goes through it. It won't schedule another job for the board, if one is currently running. ftc run-test doesn't have a run-time concurrency check, only a build-time concurrency check.
  • We definitely need to add concurrency control for a board, for ftc run-test.

fuego run scalability [edit section]

  • Khiem also noted that he sees a lot of buildup of run data that clogs the Jenkins interface
    • Tim noted that there are mechanisms for the tables to only show the last 40 entries in a chart, but nothing in Fuego to remove old run data
    • Khiem says he runs hundreds of tests a week, and the number of runs ends up clogging up the system.
    • Tim says that certain things in Fuego, like the report generation, can get really slow if there is too much run data. This is a fundamental scalability issue that needs to be addressed.
      • some --where clauses require reading every run's run.json file and some don't, so you may only see slowness on some queries.
  • one potential solutions would be to make a script which deletes old run data
  • maybe add an ftc command to remove runs.
    • could be something that uses --where clauses:
      • 'ftc rm-runs --where start_time=<"1 week ago"'

stand-alone layers [edit section]

Based on discussions with Hiramatsu-san (who was representing the LKFT project at this event), it seems like improving our layering would be good. Daniel has already (or will shortly) layer the code between Fuego and the aggregation/presentation layer - supporting kernelci, fuego and squad servers. Daniel mentioned isolating the parsing layer, as that seems to be something other systems don't have, that would be good to make available to other projects.

Tim wants to layer the software as well - including separating the parsing layer (he agrees with Daniel on this), as well as formalizing the board control and provisioning layer. Maybe we could have some preliminary stuff in the 1.4 release

release timing [edit section]

Khiem asked about the timing of releases. Tim said that 6 months is too long, which is what each of the last 2 releases have been. We should shoot for 3-month releases, even if it reduces the number of features in each release. The group discussed trying to achieve the 1.4 release in early October, prior to Embedded Linux Conference Europe, and the Automated Testing Summit. Tim will be busy most of July, and won't make much progress, but we should still be able to do something in that time period.

One thing that has stalled releases is release testing. We continue to increase the amount of Fuego self-test and release-test code, so the overhead of making a release should decrease over time.

program binary cache [edit section]

Tim mentioned that he has 2 reasons to want to do a test program binary cache:
  • to support the LAVA integration work by providing a way for LAVA worker nodes to download needed test program code independently from having a Fuego builder node
  • to support users who don't have an SDK for their board. This would include people using Fuego to self-test their host machine Due to this, Tim thinks it would be good to work on the test program binary cache. (Note: I have a prototype written that I worked on on the plane home, that might be part of this)

Priorities [edit section]

The following seem to be important priorities, based on discussions at the Jamboree:
  • ftc run-test concurrency (some kind of board lock)
  • ftc rm-run command, with where-clause support
  • isolate the parser system and make it standalone
  • create a test program binary cache

As well as all the other stuff that was mentioned in the slides. :-)
