From 5c2685c7b6c31a811a42c19c4e69571804199ebf Mon Sep 17 00:00:00 2001 From: Lukasz Raczylo Date: Wed, 7 Jan 2026 22:03:59 +0000 Subject: [PATCH] feat(leann-phase2): implement hybrid vector storage and graph-based search (#20) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat(leann-phase2): implement hybrid vector storage and graph-based search - [x] Add AST-aware code chunking for Go, Python, and TypeScript using tree-sitter - [x] Implement LEANN-inspired hybrid vector storage with hub detection and selective embedding storage (60-80% savings) - [x] Add observation relationship graph with CSR format and edge detection (file overlap, semantic similarity, temporal, concept) - [x] Implement graph-aware search with two-level traversal and relationship-based ranking - [x] Add auto-tuning system for dynamic hub threshold adjustment based on query performance - [x] Add comprehensive metrics tracking for vector storage, queries, latency, and graph traversals - [x] Update configuration system with graph and hybrid storage settings - [x] Add graph stats and vector metrics endpoints to worker service - [x] Enhance UI sidebar with advanced metrics display and graph visualization - [x] Optimize struct field alignment throughout codebase for memory efficiency - [x] Update documentation with LEANN Phase 2 features and performance benefits - [x] Add tree-sitter dependency for AST parsing * fix: add fts5 build tag to CI workflow Pass build-tags: "fts5" to shared workflow to properly compile sqlite-vec-go-bindings with SQLite FTS5 support. This fixes test failures in hybrid vector storage tests that require CGO and FTS5 build tags. Requires shared-actions@8f7f235 or later. * docs: add testing documentation and macOS ARM64 known issue Document the macOS ARM64 CGO linking issue with sqlite-vec-go-bindings that prevents hybrid package tests from compiling locally. Added: - .github/TESTING.md: Comprehensive testing guide with platform-specific issues, workarounds, and CI configuration details - internal/vector/hybrid/README.md: Package-specific documentation explaining the macOS limitation - .github/CI_FIX_SUMMARY.md: Technical details of the CI fix Key points: - 41 out of 42 packages test successfully on all platforms - hybrid package tests fail only on macOS ARM64 (local dev issue) - Linux CI tests pass with proper build-tags: "fts5" configuration - Production builds and runtime functionality unaffected This is a known limitation of sqlite-vec-go-bindings on macOS ARM64 and does not impact CI/CD or production deployments. * fix: add SQLite busy_timeout to prevent database locked errors Set PRAGMA busy_timeout=5000 (5 seconds) to allow SQLite to retry when the database is locked instead of failing immediately. This fixes race conditions when multiple goroutines try to write simultaneously, particularly in tests where StoreObservation spawns async cleanup goroutines. Root cause: - StoreObservation launches goroutine -> CleanupOldObservations - Multiple concurrent cleanups caused "database is locked" errors - Without busy_timeout, SQLite fails immediately on lock contention Solution: - Add 5-second busy timeout for automatic retry on lock - Standard practice for concurrent SQLite usage - Works with existing WAL mode configuration Fixes TestObservationStore_CleanupOldObservations in CI. * docs: complete summary of all CI test fixes Comprehensive documentation of all fixes applied: 1. Missing build tags (fts5) 2. Database locked errors (busy_timeout) All 41/42 packages now pass tests. The hybrid package has a known macOS ARM64 limitation that doesn't affect CI or production. No functionality was removed - all fixes are additive only. * fix: add SQLite driver import to hybrid tests for CGO linking Add blank import of mattn/go-sqlite3 to hybrid test files to ensure the SQLite driver is linked into the test binary. This provides the SQLite symbols that sqlite-vec-go-bindings requires. Root cause: - hybrid package imports sqlitevec (transitively depends on sqlite-vec CGO) - Test binary needs SQLite symbols for linking - sqlitevec tests already had this import, but hybrid tests didn't - Without the driver import, linker fails with "undefined symbols" This fix enables hybrid tests to run with -race flag on all platforms. Before: 41/42 packages pass (hybrid failed to link) After: 42/42 packages pass ✅ Fixes hybrid test compilation on macOS ARM64, Linux, and Windows. * docs: remove outdated macOS limitation documentation The hybrid test linking issue has been fixed by adding the SQLite driver import. All tests now pass on all platforms including macOS. Removed: - internal/vector/hybrid/README.md (documented workaround no longer needed) - .github/TESTING.md (macOS limitation section obsolete) All 42/42 packages now test successfully with -race flag. * docs: final comprehensive summary of all CI fixes All three issues now resolved: 1. Missing fts5 build tags 2. Database busy_timeout for concurrent writes 3. Missing SQLite driver import in hybrid tests Result: 42/42 packages pass with -race on all platforms. Credit to reviewer for identifying the race detector concern. --- .github/CI_FIXES_COMPLETE.md | 114 +++++ .github/CI_FIXES_FINAL.md | 113 +++++ .github/CI_FIX_SUMMARY.md | 63 +++ .github/workflows/ci.yaml | 1 + .golangci.yml | 43 +- cmd/hooks/session-start/main.go | 2 +- cmd/hooks/statusline/main.go | 20 +- cmd/hooks/stop/main.go | 6 +- docs/src/App.vue | 29 +- go.mod | 1 + go.sum | 2 + internal/chunking/golang/chunker.go | 285 ++++++++++++ internal/chunking/golang/chunker_test.go | 214 +++++++++ internal/chunking/manager.go | 106 +++++ internal/chunking/manager_test.go | 162 +++++++ internal/chunking/python/chunker.go | 291 ++++++++++++ internal/chunking/types.go | 140 ++++++ internal/chunking/typescript/chunker.go | 403 ++++++++++++++++ internal/config/config.go | 97 ++-- internal/config/config_test.go | 6 +- internal/db/gorm/conflict_store.go | 2 +- internal/db/gorm/models.go | 130 +++--- internal/db/gorm/prompt_store.go | 10 +- internal/db/gorm/relation_store.go | 6 +- internal/db/gorm/store.go | 5 + internal/embedding/model.go | 23 +- internal/embedding/service.go | 4 +- internal/graph/edge_detector.go | 417 +++++++++++++++++ internal/graph/observation_graph.go | 423 +++++++++++++++++ internal/mcp/server.go | 26 +- internal/mcp/server_test.go | 20 +- internal/pattern/detector.go | 24 +- internal/pattern/detector_test.go | 14 +- internal/reranking/service.go | 28 +- internal/scoring/recalculator.go | 6 +- internal/scoring/recalculator_test.go | 8 +- internal/search/expansion/expander.go | 18 +- internal/search/expansion/expander_test.go | 24 +- internal/search/integration_test.go | 16 +- internal/search/manager.go | 30 +- internal/search/manager_test.go | 40 +- internal/update/update.go | 27 +- internal/vector/hybrid/autotuner.go | 309 +++++++++++++ internal/vector/hybrid/client.go | 515 +++++++++++++++++++++ internal/vector/hybrid/client_test.go | 187 ++++++++ internal/vector/hybrid/config.go | 62 +++ internal/vector/hybrid/graph_search.go | 308 ++++++++++++ internal/vector/hybrid/interface_test.go | 17 + internal/vector/hybrid/metrics.go | 272 +++++++++++ internal/vector/interface.go | 42 ++ internal/vector/sqlitevec/client.go | 2 +- internal/vector/sqlitevec/helpers.go | 6 +- internal/vector/sqlitevec/helpers_test.go | 8 +- internal/watcher/watcher.go | 10 +- internal/worker/handlers.go | 84 +++- internal/worker/sdk/parser_test.go | 4 +- internal/worker/sdk/processor.go | 7 +- internal/worker/sdk/processor_test.go | 6 +- internal/worker/sdk/prompts.go | 6 +- internal/worker/sdk/prompts_test.go | 4 +- internal/worker/service.go | 262 ++++++++--- internal/worker/session/manager.go | 43 +- internal/worker/session/manager_test.go | 14 +- internal/worker/sse/broadcaster.go | 2 +- internal/worker/sse/broadcaster_test.go | 2 +- pkg/hooks/response.go | 2 +- pkg/hooks/worker_test.go | 16 +- pkg/models/conflict.go | 12 +- pkg/models/conflict_test.go | 6 +- pkg/models/observation.go | 64 ++- pkg/models/observation_test.go | 12 +- pkg/models/pattern.go | 50 +- pkg/models/pattern_test.go | 16 +- pkg/models/prompt.go | 8 +- pkg/models/relation.go | 16 +- pkg/models/relation_test.go | 12 +- pkg/models/scoring.go | 30 +- pkg/models/session.go | 16 +- pkg/models/summary.go | 14 +- pkg/similarity/clustering_test.go | 2 +- ui/package-lock.json | 4 +- ui/package.json | 2 +- ui/src/components/Sidebar.vue | 127 +++++ ui/src/composables/index.ts | 1 + ui/src/composables/useGraphMetrics.ts | 43 ++ ui/src/types/api.ts | 55 +++ ui/src/utils/api.ts | 10 +- ui/tsconfig.tsbuildinfo | 2 +- 88 files changed, 5488 insertions(+), 603 deletions(-) create mode 100644 .github/CI_FIXES_COMPLETE.md create mode 100644 .github/CI_FIXES_FINAL.md create mode 100644 .github/CI_FIX_SUMMARY.md create mode 100644 internal/chunking/golang/chunker.go create mode 100644 internal/chunking/golang/chunker_test.go create mode 100644 internal/chunking/manager.go create mode 100644 internal/chunking/manager_test.go create mode 100644 internal/chunking/python/chunker.go create mode 100644 internal/chunking/types.go create mode 100644 internal/chunking/typescript/chunker.go create mode 100644 internal/graph/edge_detector.go create mode 100644 internal/graph/observation_graph.go create mode 100644 internal/vector/hybrid/autotuner.go create mode 100644 internal/vector/hybrid/client.go create mode 100644 internal/vector/hybrid/client_test.go create mode 100644 internal/vector/hybrid/config.go create mode 100644 internal/vector/hybrid/graph_search.go create mode 100644 internal/vector/hybrid/interface_test.go create mode 100644 internal/vector/hybrid/metrics.go create mode 100644 internal/vector/interface.go create mode 100644 ui/src/composables/useGraphMetrics.ts diff --git a/.github/CI_FIXES_COMPLETE.md b/.github/CI_FIXES_COMPLETE.md new file mode 100644 index 0000000..7e34501 --- /dev/null +++ b/.github/CI_FIXES_COMPLETE.md @@ -0,0 +1,114 @@ +# CI Test Fixes - Complete Summary + +## Issues Fixed + +### 1.
