Work continues on Factory 2.0...

Recall that we have 1000 different problems we're trying to solve, but we're attempting to focus on an isolated subset for now: problems we've picked so that their solutions can enable higher-level problem solving in the coming months. The work currently includes a focus on:

• Preparing elementary build infrastructure for the Fedora 26 Alpha release.
• Deserializing pipeline processes that could be done more quickly in parallel.
• Building a dependency chain database, so that we can build smarter rebuild automation and pipeline analytics.
• Monitoring pipeline performance metrics, so that as we later improve things we can be sure we had an effect.

Overall, I'm happy with the work output of this sprint, but there are complications.

• We made significant progress on the module build infrastructure. The stack is maturing - the number of new features will be slowing as we start to prepare it for production for F26. Our proposals were approved by FESCo last week. We still have a long way to go, but we're currently on target to build an F26 Edition out of the base modules. Status: Green.
• Our deserialization effort hit some roadbumps as we negotiate how to interface with existing test-execution environments. We're not blocked at the moment and are in dialogue with our partners. We will slip a few weeks on our MvP deliverable here. Status: Yellow.
• The dependency chain MvP is ready for deployment efforts in Sprint 5. We underestimated how this work would depend on other message bus enablement pre-requisites, which has pushed our delivery date back a few weeks. Status: Yellow.
• Our performance metrics work is progressing, but much more slowly than we had initially expected. We promised a delivery date of Dec. 1st for this, but we will miss it by a wide margin and need to adjust expectations. The primary factor is that the metrics are just more complex than we anticipated. The pipeline is complex, therefore exacting meaningful measurements is complex. A separate factor is some unpredictability with write-access to the integration lab's ELK instance we are depending on. The delay in work here does not block our other efforts. Status: Red.

mbs-build-profiles, by threebean

Here we show how we're re-using the "installation profiles" feature of modulemd to define the buildsystem "build groups" for a module. It's a natural extension of the install profiles metadata which furthmore helps unblock the base-runtime team in their quest to produce the first generational core!

In this video I'm trying to explain changes in configuration internals of Module Build Service. This aims to split configuration data/logic so that it will be simplier to use and understand for contributors/users.

In this demo I inform about the support of modulemd-1.0 format in Module Build Service, describes the build-order feature and shows how the module using this feature builds using the mock builder.

This video shows the new microservice ResultsDB-Updater which listens on the CI message bus for test results and adds them to ResultsDB.

A demo showing the publication of messages from a dist-git repo to the Unified Message Bus. Shows how the repos are configured for publication on the server side, and explains a little bit about message format.
