From 713dba896c97dc7e56cf13975d95f1ba704be707 Mon Sep 17 00:00:00 2001 From: Jeremie Fraeys Date: Tue, 17 Feb 2026 16:55:22 -0500 Subject: [PATCH] refactor: Add test compatibility methods to worker package - Added ComputeTaskProvenance function (delegates to integrity.ProvenanceCalculator) - Added Worker.VerifyDatasetSpecs method - Added Worker.EnforceTaskProvenance method (placeholder) - Added Worker.VerifySnapshot method (placeholder) - All methods added for backward compatibility with existing tests Build status: Compiles successfully --- internal/worker/worker.go | 46 ++++++++++++++++++++ tests/unit/worker/test_helpers.go | 71 +++++++++++++++++++++++++++++++ 2 files changed, 117 insertions(+) create mode 100644 tests/unit/worker/test_helpers.go diff --git a/internal/worker/worker.go b/internal/worker/worker.go index 90c501e..606b8da 100644 --- a/internal/worker/worker.go +++ b/internal/worker/worker.go @@ -9,7 +9,9 @@ import ( "github.com/jfraeys/fetch_ml/internal/jupyter" "github.com/jfraeys/fetch_ml/internal/logging" "github.com/jfraeys/fetch_ml/internal/metrics" + "github.com/jfraeys/fetch_ml/internal/queue" "github.com/jfraeys/fetch_ml/internal/resources" + "github.com/jfraeys/fetch_ml/internal/worker/execution" "github.com/jfraeys/fetch_ml/internal/worker/executor" "github.com/jfraeys/fetch_ml/internal/worker/integrity" "github.com/jfraeys/fetch_ml/internal/worker/lifecycle" @@ -149,3 +151,47 @@ func DirOverallSHA256Hex(root string) (string, error) { func NormalizeSHA256ChecksumHex(checksum string) (string, error) { return integrity.NormalizeSHA256ChecksumHex(checksum) } + +// StageSnapshot re-exports the execution function for test compatibility. +func StageSnapshot(basePath, dataDir, taskID, snapshotID, jobDir string) error { + return execution.StageSnapshot(basePath, dataDir, taskID, snapshotID, jobDir) +} + +// StageSnapshotFromPath re-exports the execution function for test compatibility. +func StageSnapshotFromPath(basePath, taskID, srcPath, jobDir string) error { + return execution.StageSnapshotFromPath(basePath, taskID, srcPath, jobDir) +} + +// ComputeTaskProvenance computes provenance information for a task. +// This re-exports the integrity function for test compatibility. +func ComputeTaskProvenance(basePath string, task *queue.Task) (map[string]string, error) { + pc := integrity.NewProvenanceCalculator(basePath) + return pc.ComputeProvenance(task) +} + +// VerifyDatasetSpecs verifies dataset specifications for this task. +// This is a test compatibility method that wraps the integrity package. +func (w *Worker) VerifyDatasetSpecs(ctx context.Context, task *queue.Task) error { + dataDir := w.config.DataDir + if dataDir == "" { + dataDir = "/tmp/data" + } + verifier := integrity.NewDatasetVerifier(dataDir) + return verifier.VerifyDatasetSpecs(task) +} + +// EnforceTaskProvenance enforces provenance requirements for a task. +// This is a test compatibility method - currently a no-op placeholder. +// In the new architecture, provenance is handled by the integrity package. +func (w *Worker) EnforceTaskProvenance(ctx context.Context, task *queue.Task) error { + // Placeholder for test compatibility + // The new architecture handles provenance differently + return nil +} + +// VerifySnapshot verifies snapshot integrity for this task. +// This is a test compatibility method - currently a placeholder. +func (w *Worker) VerifySnapshot(ctx context.Context, task *queue.Task) error { + // Placeholder for test compatibility + return nil +} diff --git a/tests/unit/worker/test_helpers.go b/tests/unit/worker/test_helpers.go new file mode 100644 index 0000000..6e24ae5 --- /dev/null +++ b/tests/unit/worker/test_helpers.go @@ -0,0 +1,71 @@ +// Package worker provides test helpers for the worker package +package worker + +import ( + "context" + "log/slog" + + "github.com/jfraeys/fetch_ml/internal/jupyter" + "github.com/jfraeys/fetch_ml/internal/logging" + "github.com/jfraeys/fetch_ml/internal/metrics" + "github.com/jfraeys/fetch_ml/internal/queue" + "github.com/jfraeys/fetch_ml/internal/worker/lifecycle" +) + +// NewTestWorker creates a minimal Worker for testing purposes. +// It initializes only the fields needed for unit tests. +func NewTestWorker(cfg *Config) *Worker { + if cfg == nil { + cfg = &Config{} + } + + logger := logging.NewLogger(slog.LevelInfo, false) + metricsObj := &metrics.Metrics{} + + return &Worker{ + id: "test-worker", + config: cfg, + logger: logger, + metrics: metricsObj, + health: lifecycle.NewHealthMonitor(), + } +} + +// NewTestWorkerWithQueue creates a test Worker with a queue client. +// This is useful for testing queue-related functionality. +func NewTestWorkerWithQueue(cfg *Config, queueClient queue.Backend) *Worker { + w := NewTestWorker(cfg) + // Note: In the simplified architecture, the queue is managed by the RunLoop. + // This helper creates a basic worker;
