From 9db67d0148b0fab33a0be8d033b2e997fbb0d475 Mon Sep 17 00:00:00 2001 From: David Snelling Date: Tue, 4 Nov 2025 13:05:59 -0800 Subject: [PATCH] fix: resolve critical COW ref resolution and versioning bugs Fixed three critical bugs in v5.3.0: 1. COW ref resolution bug (lines 2354, 2856, 2895 in src/brainy.ts): - getHistory(), commit(), deleteBranch() were prepending 'heads/' to branch names - This caused RefManager to resolve 'heads/main' to 'refs/heads/heads/main' - Actual ref file at 'refs/heads/main' could not be found - Result: "Ref not found: heads/main" error breaking all COW operations 2. VersionManager commitHash bug (lines 212, 222 in src/versioning/VersionManager.ts): - save() was assigning entire Ref object to commitHash instead of ref.commitHash - Expected string, got object causing type mismatches in version metadata 3. Test mock improvements (tests/unit/versioning/VersionManager.test.ts): - Fixed searchByMetadata to skip metadata check for 'type' property - Added glob pattern support for tag filtering (e.g. 'v1.*') - Added deleteNounMetadata mock - Fixed getNounMetadata to return null for missing version entities Fixes: - src/brainy.ts (3 lines): Remove 'heads/' prefix from ref resolution calls - src/versioning/VersionManager.ts (2 lines): Use ref.commitHash instead of ref - tests/unit/versioning/VersionManager.test.ts: Fix test mocks - tests/integration/history-ref-resolution-bug.test.ts: Add regression tests Test Results: - Before: 16 test failures - After: 0 failures in VersionManager tests, 1183/1208 total tests passing (98%) --- src/brainy.ts | 6 +- src/versioning/VersionManager.ts | 4 +- .../history-ref-resolution-bug.test.ts | 142 ++++++++++++++++++ tests/unit/versioning/VersionManager.test.ts | 33 +++- 4 files changed, 175 insertions(+), 10 deletions(-) create mode 100644 tests/integration/history-ref-resolution-bug.test.ts diff --git a/src/brainy.ts b/src/brainy.ts index 865a7827..cb5028e1 100644 --- a/src/brainy.ts +++ b/src/brainy.ts @@ -2351,7 +2351,7 @@ export class Brainy implements BrainyInterface { const currentBranch = await this.getCurrentBranch() // Get current HEAD commit (parent) - const currentCommitHash = await refManager.resolveRef(`heads/${currentBranch}`) + const currentCommitHash = await refManager.resolveRef(currentBranch) // Get current state statistics const entityCount = await this.getNounCount() @@ -2853,7 +2853,7 @@ export class Brainy implements BrainyInterface { } const refManager = (this.storage as any).refManager - await refManager.deleteRef(`heads/${branch}`) + await refManager.deleteRef(branch) }) } @@ -2892,7 +2892,7 @@ export class Brainy implements BrainyInterface { const currentBranch = await this.getCurrentBranch() // Get commit history for current branch - const commits = await commitLog.getHistory(`heads/${currentBranch}`, { + const commits = await commitLog.getHistory(currentBranch, { maxCount: options?.limit || 10 }) diff --git a/src/versioning/VersionManager.ts b/src/versioning/VersionManager.ts index 0fa04141..45a5778f 100644 --- a/src/versioning/VersionManager.ts +++ b/src/versioning/VersionManager.ts @@ -209,7 +209,7 @@ export class VersionManager { // Get the commit hash that was just created const refManager = this.brain.refManager const ref = await refManager.getRef(currentBranch) - commitHash = ref + commitHash = ref.commitHash } else { // Use current HEAD commit const refManager = this.brain.refManager @@ -219,7 +219,7 @@ export class VersionManager { `No commit exists on branch ${currentBranch}.
