From 9ed6c2638d42d71782a043720de718a55136e587 Mon Sep 17 00:00:00 2001 From: Test Date: Sun, 23 Aug 2026 17:24:46 -0700 Subject: [PATCH] feat(T2.7): implement workflow history pruning MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add internal/history package for pruning workflow history - Implement HistoryPruner with configurable pruning policies - Automatic pruning on size/age/count thresholds - Archive old entries to disk for compliance - Memory-efficient history management - Continue-as-new compatible design - 17 history tests, all passing Features: - AddEntry() for adding task history - Automatic pruning by: - Maximum history size (default 100MB) - Maximum entry age (default 24 hours) - Maximum entry count (default 1000) - Manual Prune() trigger - GetEntries() with filters (status, time range, recent) - UpdateEntry() for status changes - Archive old entries to configurable directory - Clear() to reset history Pruning Strategy: - Entries sorted by end time (oldest first) - Remove entries exceeding any threshold - Archive to disk for historical analysis - Keep recent entries for debugging - 90% threshold triggers auto-pruning Memory Management: - Constant memory growth even with 1000s of tasks - Estimated size calculated per entry - Size ratio tracked (current vs max) - Memory info reporting Statistics: - Total size and entry count - Average entry size - Prune and archive counts - Last prune timestamp - Usage ratio (%) - Memory growth rate Archival: - Optional archive directory - Entries saved as JSON for analysis - Timestamp included in filename - Non-blocking archive operations Test Coverage: - 17 history tests (add, query, prune, archive) - Constant memory growth verified (1000 tasks) - Age-based pruning verified - Archive directory creation tested - Status filtering tested - Recent entries retrieval tested - Update operations tested - Policy defaults verified Verification: - Memory stays within bounds ✓ - Old entries pruned correctly ✓ - Recent entries preserved ✓ - Archive functionality working ✓ - Concurrent safe (RWMutex) ✓ Next: T2.8 (Distributed lock optimization) --- internal/history/pruner.go | 332 ++++++++++++++++++++++++ internal/history/pruner_test.go | 434 ++++++++++++++++++++++++++++++++ tasks/board-T2.md | 2 +- 3 files changed, 767 insertions(+), 1 deletion(-) create mode 100644 internal/history/pruner.go create mode 100644 internal/history/pruner_test.go diff --git a/internal/history/pruner.go b/internal/history/pruner.go new file mode 100644 index 0000000..e1f8cbb --- /dev/null +++ b/internal/history/pruner.go @@ -0,0 +1,332 @@ +package history + +import ( + "encoding/json" + "fmt" + "os" + "sort" + "sync" + "time" +) + +// TaskHistory represents a single task execution in history +type TaskHistory struct { + TaskID string `json:"task_id"` + Status string `json:"status"` // "pending", "completed", "failed" + StartTime time.Time `json:"start_time"` + EndTime time.Time `json:"end_time"` + Duration time.Duration `json:"duration"` + Output map[string]interface{} `json:"output,omitempty"` + Error string `json:"error,omitempty"` + Metrics map[string]interface{} `json:"metrics,omitempty"` + Size int64 `json:"size"` // Estimated size in bytes +} + +// PrunePolicy defines how to prune history +type PrunePolicy struct { + MaxHistorySize int64 // Max total history size in bytes (e.g., 100MB) + MaxHistoryAge time.Duration // Max age of history entries (e.g., 24 hours) + MaxEntries int // Max number of entries to keep (e.g., 1000) + ArchiveDir string // Directory to archive pruned items +} + +// HistoryPruner manages workflow history with automatic pruning +type HistoryPruner struct { + mu sync.RWMutex + entries []*TaskHistory + policy PrunePolicy + totalSize int64 + pruneCount int + archiveCount int + lastPruneTime time.Time + pruneThreshold int64 // Size threshold that triggers pruning +} + +// NewHistoryPruner creates a new history pruner +func NewHistoryPruner(policy PrunePolicy) *HistoryPruner { + if policy.MaxHistorySize == 0 { + policy.MaxHistorySize = 100 * 1024 * 1024 // 100MB default + } + if policy.MaxHistoryAge == 0 { + policy.MaxHistoryAge = 24 * time.Hour // 24 hours default + } + if policy.MaxEntries == 0 { + policy.MaxEntries = 1000 // 1000 entries default + } + + // Set prune threshold at 90% of max size + pruneThreshold := (policy.MaxHistorySize * 9) / 10 + + return &HistoryPruner{ + entries: make([]*TaskHistory, 0), + policy: policy, + pruneThreshold: pruneThreshold, + } +} + +// AddEntry adds a task history entry +func (hp *HistoryPruner) AddEntry(entry *TaskHistory) error { + if entry == nil { + return fmt.Errorf("entry cannot be nil") + } + + hp.mu.Lock() + defer hp.mu.Unlock() + + // Estimate size + data, _ := json.Marshal(entry) + entry.Size = int64(len(data)) + + hp.entries = append(hp.entries, entry) + hp.totalSize += entry.Size + + // Check if pruning is needed + if hp.totalSize > hp.pruneThreshold || len(hp.entries) > hp.policy.MaxEntries { + hp.pruneLocked() + } + + return nil +} + +// pruneLocked prunes old entries based on policy (must be called with lock held) +func (hp *HistoryPruner) pruneLocked() { + if len(hp.entries) == 0 { + return + } + + // Sort by end time (oldest first) + sort.Slice(hp.entries, func(i, j int) bool { + return hp.entries[i].EndTime.Before(hp.entries[j].EndTime) + }) + + // Archive old entries + var toKeep []*TaskHistory + newTotalSize := int64(0) + now := time.Now() + + for _, entry := range hp.entries { + age := now.Sub(entry.EndTime) + + // Keep if: + // 1.
