Jeremie Fraeys	51698d60de	refactor(phase7): Restore resource metrics in metrics.go ... - Re-enabled all resource metrics (CPU, GPU, acquisition stats) - Metrics are conditionally registered only when w.resources != nil - Added nil check to prevent panics if resource manager not initialized Build status: Compiles successfully	2026-02-17 16:38:47 -05:00
Jeremie Fraeys	1ba67e419d	refactor(phase7): Integrate resource manager into Worker ... - Added resources field to Worker struct - Updated factory.go to pass resource manager to Worker - Removed placeholder discard of resource manager - Build compiles successfully	2026-02-17 16:37:33 -05:00
Jeremie Fraeys	a7360869f8	refactor: Implement TaskExecutorAdapter and Worker.runningCount() ... - Created executor/TaskExecutorAdapter implementing lifecycle.TaskExecutor - Properly wires LocalExecutor and ContainerExecutor through adapter - Worker.runningCount() now delegates to runLoop.RunningCount() - Added lifecycle.RunLoop.RunningCount() public method - factory.go creates proper executor chain instead of placeholder Build status: Compiles successfully	2026-02-17 16:15:41 -05:00
Jeremie Fraeys	38fa017b8e	refactor: Phase 6 - Complete migration, remove legacy files ... BREAKING CHANGE: Legacy worker files removed, Worker struct simplified Changes: 1. worker.go - Simplified to 8 fields using composed dependencies: - runLoop, runner, metrics, health (from new packages) - Removed: server, queue, running, datasetCache, ctx, cancel, etc. 2. factory.go - Updated NewWorker to use new structure - Uses lifecycle.NewRunLoop - Integrates jupyter.Manager properly 3. Removed legacy files: - execution.go (1,016 lines) - data_integrity.go (929 lines) - runloop.go (555 lines) - jupyter_task.go (144 lines) - simplified.go (demonstration no longer needed) 4. Fixed references to use new packages: - hash_selector.go -> integrity.DirOverallSHA256Hex - snapshot_store.go -> integrity.NormalizeSHA256ChecksumHex - metrics.go - Removed resource-dependent metrics temporarily 5. Added RecordQueueLatency to metrics.Metrics for lifecycle.MetricsRecorder Worker struct: 27 fields -> 8 fields (70% reduction) Build status: Compiles successfully	2026-02-17 14:39:48 -05:00
Jeremie Fraeys	94bb52d09c	refactor: Phase 5 - Simplified Worker demonstration ... Created simplified.go demonstrating target architecture: internal/worker/simplified.go (109 lines) - SimplifiedWorker struct with 6 fields vs original 27 fields - Uses composed dependencies from previous phases: - lifecycle.RunLoop for task lifecycle management - executor.JobRunner for job execution - lifecycle.HealthMonitor for health tracking - lifecycle.MetricsRecorder for metrics Key improvements demonstrated: - Dependency injection via SimplifiedWorkerConfig - Clear separation of concerns - No direct resource access (queue, metrics, etc.) - Each component implements a defined interface - Easy to test with mock implementations Note: This is a demonstration of the target architecture. The original Worker struct remains for backward compatibility. Migration would happen incrementally in future PRs. Build status: Compiles successfully	2026-02-17 14:24:40 -05:00
Jeremie Fraeys	062b78cbe0	refactor: Phase 4 - Extract lifecycle types and interfaces ...

Jeremie Fraeys	83ca393ebc	fix: Add proper WebSocket compatibility shim for test imports ... Updated api/ws_compat.go to properly delegate to api/ws package: - NewWSHandler returns http.Handler interface (not interface{}) - All Opcode* constants re-exported from ws package - Maintains backward compatibility for existing tests This allows gradual migration of tests to use api/ws directly without breaking the build.
