Silent Cancellations (No Console Spam) **Problem**: TokenStatsWorker only allows 1 calculation globally. When rapid events trigger calculations (tool-call-end, stream-end), newer calculation cancels older one → error logged + empty cache. **Fix**: Check error message in catch block: - Cancellation → return early (no cache, no log) - Real error → log and cache empty result **Effect**: Clean console, cancelled calculations can retry ## 2. Lazy Loading on Every Access **Problem**: Lazy trigger was inside MapStore.get() computation function. MapStore caches computation result → trigger only runs on first access → workspace switches don't trigger → "No consumer data available" forever. **Fix**: Move lazy trigger OUTSIDE MapStore.get(): - Added helpers: getCachedState(), isPending(), getStateSync() - Trigger runs on EVERY getWorkspaceConsumers() call - MapStore.get() just returns state (handles subscriptions) **Effect**: Workspace switch → trigger fires → calculation schedules ✓ ## Architecture Improvements **WorkspaceConsumerManager**: - Added helper methods for clean separation - Enhanced comments explaining responsibilities - Single responsibility: tokenization execution **WorkspaceStore**: - Orchestration layer (decides when to calculate) - Lazy trigger runs on every access (not cached by MapStore) - Comments explain dual-cache design **Dual-Cache Design**: - WorkspaceConsumerManager.cache: Source of truth (data) - WorkspaceStore.consumersStore (MapStore): Subscriptions only Net: +35 lines (helpers, comments, improved logic) --- src/stores/WorkspaceConsumerManager.ts | 64 +++++++++++++++++--------- src/stores/WorkspaceStore.ts | 23 +++++++-- 2 files changed, 61 insertions(+), 26 deletions(-) diff --git a/src/stores/WorkspaceConsumerManager.ts b/src/stores/WorkspaceConsumerManager.ts index f76360c0f..82b9a6553 100644 --- a/src/stores/WorkspaceConsumerManager.ts +++ b/src/stores/WorkspaceConsumerManager.ts @@ -8,12 +8,21 @@ import type { StreamingMessageAggregator } from "@/utils/messages/StreamingMessa * * Responsibilities: * - Debounces rapid calculation requests (e.g., multiple tool-call-end events) - * - Caches calculated results to avoid redundant work + * - Caches calculated results to avoid redundant work (source of truth) * - Tracks calculation state per workspace - * - Provides lazy calculation trigger for workspace switching + * - Executes Web Worker tokenization calculations + * - Handles cleanup and disposal * - * This class is extracted from WorkspaceStore to keep concerns separated - * and make the calculation logic easier to test and maintain. + * Architecture: + * - Single responsibility: consumer tokenization calculations + * - Owns the source-of-truth cache (calculated consumer data) + * - WorkspaceStore orchestrates (decides when to calculate) + * - This manager executes (performs calculations, manages cache) + * + * Dual-Cache Design: + * - WorkspaceConsumerManager.cache: Source of truth for calculated data + * - WorkspaceStore.consumersStore (MapStore): Subscription management only + * (components subscribe to workspace changes, delegates to manager for state) */ export class WorkspaceConsumerManager { // Web Worker for tokenization (shared across workspaces) @@ -37,26 +46,29 @@ export class WorkspaceConsumerManager { } /** - * Get consumer state for a workspace. - * Triggers lazy calculation if workspace has messages but no cached data. + * Get cached state without side effects. + * Returns null if no cache exists. */ - getState( - workspaceId: string, - aggregator: StreamingMessageAggregator | undefined, - isCaughtUp: boolean - ): WorkspaceConsumersState { - // Check if we need to trigger calculation BEFORE returning cached state - const cached = this.cache.get(workspaceId); - const isCalculating = this.pendingCalcs.has(workspaceId); + getCachedState(workspaceId: string): WorkspaceConsumersState | null { + return this.cache.get(workspaceId) ??
