Summary

production.md still showed the old 9-step shutdown sequence. With core v0.2.0, the sequence has 12 steps including PreStop, worker cancel, and PostStop hooks.

This commit was originally pushed to #81 but didn't make it into the squash merge.

Changes

  • Update shutdown sequence to match actual core.go Stop() in v0.2.0
  • Add cross-links to signals.md and readiness.md

Summary by CodeRabbit

  • Documentation
    • Updated graceful shutdown tuning documentation with a comprehensive termination flow description, detailing the full shutdown process steps and lifecycle phases.
    • Added cross-references to shutdown lifecycle and readiness patterns documentation for better production guidance.

Walkthrough

The documentation for graceful shutdown tuning in howto/production.md is updated to clarify the complete termination flow: Kubernetes lifecycle.preStop, followed by SIGTERM, then ColdBrew's shutdown process. Shutdown steps are reordered to include PreStop(ctx) hooks, worker context cancellation, and PostStop(ctx) hooks, with references added for related patterns.

Changes

Cohort / File(s) Summary
Documentation Updates
howto/production.md		 Updated "Graceful shutdown tuning" section to describe the full termination flow starting with Kubernetes lifecycle hooks, followed by PreStop(ctx) on CBPreStopper services, worker context cancellation, and PostStop(ctx) on CBPostStopper services. Added cross-references to Shutdown Lifecycle and Readiness Patterns sections.

Poem

🐰 With hooks both pre and post aligned,
The shutdown dance is now redesigned—
Workers wait, then gracefully depart,
ColdBrew's rhythm, a thoughtful art. ✨
