Production pipeline tools

Pipeline, Assets, and IO:

  • Flamenco:
    • Embed static files of the webapp in the Manager executable, and serve them on /app/. The root (/) URL will redirect there.
    • Embed the Blender add-on inside the Manager executable, so that the right version can always be downloaded from its web interface.
    • Add little Go program to create a ZIP of the Blender add-on. This will allow building the Manager without requiring access to a ZIP CLI program.
    • Refactor some code, replacing os.IsNotExist() (old) with errors.Is(err, fs.ErrNotExist() (new & recommended).
    • ✅ Plan: add API endpoints for fetching the last-rendered images of a certain job.
    • ✅ Plan: add SocketIO notification about new last-rendered images.
    • ✅ Plan: deploy Flamenco 3 alpha on the Blender Studio infrastructure.
    • Add Manager-global (in contrast to per-job) last-rendered image, and auto-refresh on web interface.
  • Reviews:

    • D13844: Constraints: introduce wrapper functions to access target lists.

Production pipeline tools

Pipeline, Assets, and IO:

  • Flamenco:
    • Implement API endpoint to fetch worker info in web frontend
    • Store Flamenco version (as used by Worker) in the Manager's database.
    • Changed SocketIO subscriptions so that clients don't automatically get all job updates. This includes adding a way to subscribe to "all job updates" and "all worker updates".
    • Allow Worker status change requests from web interface, and show these in the web interface.
    • Add handling of lazy/forced status change requests to Manager.
    • Add cancelling of status change requests, by requesting the current state of the Worker (i.e. when it's awake, and asleep has been requested, to cancel that request just overwrite it with another request to go to awake state).
    • Remove the shutdown state; it was only used to request the worker to sign off and go offline. This can now be done simply by requesting the offline state instead. This not only reduces the number of possible states, but also sticks to the "request the state you want the worker to be in" approach.
    • Keep track on the Manager of when a worker last 'touched' a task. This will be used later to monitor for timeouts.

    • D14964: remove action edited tab from NLA strip select

Production pipeline tools

Pipeline, Assets, and IO:

  • ☐ Plan: review D14853
  • Flamenco:
    • Filter bar to filter tasks and jobs by their status.
    • Task log pub/sub system for broadcasting task logs from Manager to the web interface.
    • Pop-over in the footer of the web interface, with two tabs:
      • History of notifications received by this run of the web interface.
      • Task log of the active task. This consists of the most recent 2kB of the task's log, plus any new log lines received via SocketIO.
    • Increase worker log chunk size from 1kB to 10kB. This reduces the number of calls it needs to do, improving performance and reducing load on the Manager.

Asset Browser/Pose Library:

Pipeline, Assets, and IO:

  • Flamenco
    • Add system for subscribing to SocketIO updates of specific jobs.
    • Send task changes to the SocketIO "room" specific to the tasks' jobs.
    • OAPI: remove '-dirty' suffix from the version number in generated code. In practice there are always some pending changes in the Git repo when OpenAPI code is generated, so the -dirty suffix doesn't add much.
    • Add /api/tasks/{task_id} endpoint to fetch single tasks.
    • Show the selected task in the web client, and update it according to what's received via SocketIO.
    • Rework mass-updates to tasks (like requeueing all tasks when a job gets requeued) so that each task change sends a notification via SocketIO.

    • D14719: Key the Current Influence Value of the Strip when Pushing Down the First NLA Track

Production pipeline tools

Pipeline, Assets, and IO:

  • Flamenco:
    • Fixed a bunch of race conditions in Master and Worker.
    • Web interface: use Pinia for state management.
    • Web interface: add notification bar.
    • Web interface: add Action buttons to perform actions on selected jobs.
    • Add "Activity" field to jobs, which will contain a description of the latest activity on the job. Currently it just contains the reason for state changes.
    • Add job actions for cancelling and requeueing jobs.
    • Reduce password strength of workers. These passwords are not meant to provide absolute security, but rather as a way to distinguish between different machines that happen to be configured with the same hostname (and thus the same Worker nickname). The password check was two orders of magnitude slower than the actual API call, though (50ms resp. 500µs).
