  v5.6.0 - Fix getRelations() Bug for Fresh Instances Stable

  dpsifr released this 2025-11-06 23:25:32 +01:00 | 594 commits to main since this release

  🐛 Critical Bug Fix

  Fixed critical bug where getRelations() returned empty array despite relationships existing. This affected ALL 8 storage adapters when called without filters.

  Root Cause

  The bug was a simple parameter default issue:

  • getVerbs() called getVerbsWithPagination() without passing offset
  • offset was undefined → targetCount = undefined + 100 = NaN
  • Loop condition collectedVerbs.length < NaN was always false
  • Loop never ran → returned 0 results

  The Fix

  Two-line change:

  // Default offset to 0 if undefined
  const { limit, offset = 0, filter } = options
  

  Applied to:

  • getVerbsWithPagination() (line 1183)
  • getNounsWithPagination() (line 1051)

  Impact

  Fixed:

  • ✅ Workshop bug report: 1,141 relationships exist but getRelations() returned empty array
  • ✅ All fresh Brainy instances (MemoryStorage, FileSystemStorage, etc.)
  • ✅ Affects all 8 storage adapters (all extend BaseStorage)

  Performance:

  • ✅ No degradation - optimizations now work as designed
  • ✅ Type skipping verified: checked 1 type, skipped 126 empty types
  • ✅ Early termination verified: stopped at limit
  • ✅ Billion-scale safe: bounded memory, streaming, type-aware

  Not Affected:

  • Filtered queries: getRelations({ from: id }), getRelations({ to: id })
  • Queries with type filter: getRelations({ type: 'relatedTo' })

  Test Results

  MemoryStorage ✅

  Layer 1 (getVerbsByType_internal): 1 verbs ✅
  Layer 2 (getVerbs with filter): 1 verbs ✅
  Layer 3 (getVerbs no filter): 1 verbs ✅  ← FIXED!
  Layer 4 (brain.getRelations()): 1 relations ✅  ← FIXED!
  

  FileSystemStorage ✅

  brain.getRelations(): 1 relationships ✅
  storage.getVerbs(): 1 verbs ✅
