Description

OOB setup messages generated by the foreground service CLI were not visible when an application embedded CloudXRService. This made a disconnected HMD appear to be waiting silently.

Move waiting, setup, and recovery progress reporting into the shared service so both foreground and embedded operators receive it. Add progress before web-client asset checks, check required USB-local ports before reporting preflight success, and log fatal OOB failures once from the shared service. Existing streaming connection/disconnection messages remain unchanged.

Type of change

  • Bug fix (non-breaking change which fixes an issue)

Testing

On the local Linux development machine with Python 3.12:

  • Configured and built the Isaac Capture package with CMake.
  • Ran the complete CloudXR Python test leaf against the built package: 596 passed.
  • Ran SKIP=check-copyright-year pre-commit run --all-files: passed.

Checklist

  • I have read and understood the contribution guidelines.
  • I have run the linter and formatter with SKIP=check-copyright-year pre-commit run --all-files.
  • Documentation assessed; no documentation change was needed for these existing OOB workflows.
  • I have added tests that prove the fix works.
  • I have signed off all my commits (git commit -s) per the DCO.

Summary by CodeRabbit

  • New Features
    • Added clearer, stage-based setup and recovery progress messages, including updates for device detection, browser readiness, and delayed recovery.
    • Progress notices are rate-limited to reduce repeated messages.
  • Bug Fixes
    • Prevented duplicate console warnings when setup diagnostics are shared across service startup.
    • Avoided reporting browser readiness as active streaming before stream status is confirmed.

📝 Walkthrough

CloudXRService now reports OOB progress during host preflight, runtime startup, and status publication. OobProgressReporter derives messages from lifecycle snapshots and limits repeated wait and recovery-delay messages. Host preflight warnings remain logged when console output is suppressed. The CLI no longer drains OOB updates to report progress and returns an error for fatal OOB status during setup.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Operators may see only one recovery-delay message during a prolonged degraded state instead of periodic reminders. Streaming and data are unaffected, so this is mergeable with a small follow-up fix.

Allow recovery-delay reminders without a stage change.

If the service repeats the same DEGRADED snapshot, entered is false. The 30-second reminder check does not run, so recovery-delay reminders stop after the first message. Check the delay timer for every degraded snapshot, while keeping the stage-change check for transition messages.

The logs seem a little too many for me. And OobProgressReporter can’t set log level, it can be a little tricky when we add more and more to the observations. Please consider adding log level or decreasing the logs amount
