From 5e9efd11d9ec325f025204c95f14128255a409f9 Mon Sep 17 00:00:00 2001 From: David Snelling Date: Thu, 6 Nov 2025 14:24:32 -0800 Subject: [PATCH] fix: resolve getRelations() returning empty array for fresh instances MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixed critical bug where getRelations() returned empty array despite relationships existing. The bug affected ALL 8 storage adapters when called without filters. Root Cause: - getVerbs() called getVerbsWithPagination() without passing offset parameter - offset was undefined → targetCount = undefined + limit = NaN - Loop condition (collectedVerbs.length < NaN) = false → loop never ran The Fix: - Default offset to 0 in getNounsWithPagination() and getVerbsWithPagination() - Add conditional optimization: only skip empty types if counts are reliable - Preserves all billion-scale optimizations (type skipping, early termination, bounded memory) Impact: - Fixes Workshop bug report: 1,141 relationships exist but getRelations() returned [] - Fixes all fresh Brainy instances (MemoryStorage, FileSystemStorage, etc.) - No performance degradation - optimizations now work as designed Test Results: - MemoryStorage: getRelations() returns correct results ✅ - FileSystemStorage: getRelations() returns correct results ✅ - Type skipping verified: checked 1 type, skipped 126 empty types ✅ - Early termination verified: stopped at limit ✅ Closes: Workshop team bug report (getRelations returns empty array) --- src/storage/baseStorage.ts | 78 +++++++++++++++++++++++++++++++++----- 1 file changed, 69 insertions(+), 9 deletions(-) diff --git a/src/storage/baseStorage.ts b/src/storage/baseStorage.ts index c800e762..8d2faf82 100644 --- a/src/storage/baseStorage.ts +++ b/src/storage/baseStorage.ts @@ -157,6 +157,9 @@ export abstract class BaseStorage extends BaseStorageAdapter { protected nounTypeCache = new Map() protected verbTypeCache = new Map() + // v5.5.0: Track if type counts have been rebuilt (prevent repeated rebuilds) + private typeCountsRebuilt = false + /** * Analyze a storage key to determine its routing and path * @param id - The key to analyze (UUID or system key) @@ -1045,14 +1048,18 @@ export abstract class BaseStorage extends BaseStorageAdapter { }> { await this.ensureInitialized() - const { limit, offset, filter } = options + const { limit, offset = 0, filter } = options const collectedNouns: HNSWNounWithMetadata[] = [] const targetCount = offset + limit // Early termination target + // v5.5.0 BUG FIX: Only use optimization if counts are reliable + const totalNounCountFromArray = this.nounCountsByType.reduce((sum, c) => sum + c, 0) + const useOptimization = totalNounCountFromArray > 0 + // v5.5.0: Iterate through noun types with billion-scale optimizations for (let i = 0;
