Changelog

All notable changes to GitNexus will be documented in this file.

[Unreleased]

Changed

  • Migrated from KuzuDB to LadybugDB v0.15 (@ladybugdb/core, @ladybugdb/wasm-core)
  • Renamed all internal paths from kuzu to lbug (storage: .gitnexus/kuzu → .gitnexus/lbug)
  • Added automatic cleanup of stale KuzuDB index files
  • LadybugDB v0.15 requires explicit VECTOR extension loading for semantic search

[1.4.0] - 2026-03-13

Added

  • Language-aware symbol resolution engine with 3-tier resolver: exact FQN → scope-walk → guarded fuzzy fallback that refuses ambiguous matches (#238) — @magyargergo
  • Method Resolution Order (MRO) with 5 language-specific strategies: C++ leftmost-base, C#/Java class-over-interface, Python C3 linearization, Rust qualified syntax, default BFS (#238) — @magyargergo
  • Constructor & struct literal resolution across all languages — new Foo(), User{...}, C# primary constructors, target-typed new (#238) — @magyargergo
  • Receiver-constrained resolution using per-file TypeEnv — disambiguates user.save() vs repo.save() via ownerId matching (#238) — @magyargergo
  • Heritage & ownership edges — HAS_METHOD, OVERRIDES, Go struct embedding, Swift extension heritage, method signatures (parameterCount, returnType) (#238) — @magyargergo
  • Language-specific resolver directory (resolvers/) — extracted JVM, Go, C#, PHP, Rust resolvers from monolithic import-processor (#238) — @magyargergo
  • Type extractor directory (type-extractors/) — per-language type binding extraction with Record<SupportedLanguages, Handler> + satisfies dispatch (#238) — @magyargergo
  • Export detection dispatch table — compile-time exhaustive Record + satisfies pattern replacing switch/if chains (#238) — @magyargergo
  • Language config module (language-config.ts) — centralized tsconfig, go.mod, composer.json, .csproj, Swift package config loaders (#238) — @magyargergo
  • Optional skill generation via npx gitnexus analyze --skills — generates AI agent skills from KuzuDB knowledge graph (#171) — @zander-raycraft
  • First-class C# support — sibling-based modifier scanning, record/delegate/property/field/event declaration types (#163, #170, #178 via #237) — @Alice523, @benny-yamagata, @jnMetaCode
  • C/C++ support fixes — .h → C++ mapping, static-linkage export detection, qualified/parenthesized declarators, 48 entry point patterns (#163, #227 via #237) — @Alice523, @bitgineer
  • Rust support fixes — sibling-based visibility_modifier scanning for pub detection (#227 via #237) — @bitgineer
  • Adaptive tree-sitter buffer sizing — Math.min(Math.max(contentLength * 2, 512KB), 32MB) (#216 via #237) — @JasonOA888
  • Call expression matching in tree-sitter queries (#234 via #237) — @ex-nihilo-jg
  • DeepSeek model configurations (#217) — @JasonOA888
  • 282+ new unit tests, 178 integration resolver tests across 9 languages, 53 test files, 1146 total tests passing

Fixed

  • Skip unavailable native Swift parsers in sequential ingestion (#188) — @Gujiassh
  • Heritage heuristic language-gated — no longer applies class/interface rules to wrong languages (#238) — @magyargergo
  • C# base_list distinguishes EXTENDS vs IMPLEMENTS via symbol table + I[A-Z] heuristic (#238) — @magyargergo
  • Go qualified_type (models.User) correctly unwrapped in TypeEnv (#238) — @magyargergo
  • Global tier no longer blocks resolution when kind/arity filtering can narrow to 1 candidate (#238) — @magyargergo

Changed

  • import-processor.ts reduced from 1412 → 711 lines (50% reduction) via resolver and config extraction (#238) — @magyargergo
  • type-env.ts reduced from 635 → ~125 lines via type-extractor extraction (#238) — @magyargergo
  • CI/CD workflows hardened with security fixes and fork PR support (#222, #225) — @magyargergo

[1.3.11] - 2026-03-08

Security

  • Fix FTS Cypher injection by escaping backslashes in search queries (#209) — @magyargergo

Added

  • Auto-reindex hook that runs gitnexus analyze after commits and merges, with automatic embeddings preservation (#205) — @L1nusB
  • 968 integration tests (up from ~840) covering unhappy paths across search, enrichment, CLI, pipeline, worker pool, and KuzuDB (#209) — @magyargergo
  • Coverage auto-ratcheting so thresholds bump automatically on CI (#209) — @magyargergo
  • Rich CI PR report with coverage bars, test counts, and threshold tracking (#209) — @magyargergo
  • Modular CI workflow architecture with separate unit-test, integration-test, and orchestrator jobs (#209) — @magyargergo

Fixed

  • KuzuDB native addon crashes on Linux/macOS by running integration tests in isolated vitest processes with --pool=forks (#209) — @magyargergo
  • Worker pool MODULE_NOT_FOUND crash when script path is invalid (#209) — @magyargergo

Changed

  • Added macOS to the cross-platform CI test matrix (#208) — @magyargergo

[1.3.10] - 2026-03-07

Security

  • MCP transport buffer cap: Added 10 MB MAX_BUFFER_SIZE limit to prevent out-of-memory attacks via oversized Content-Length headers or unbounded newline-delimited input
  • Content-Length validation: Reject Content-Length values exceeding the buffer cap before allocating memory
  • Stack overflow prevention: Replaced recursive readNewlineMessage with iterative loop to prevent stack overflow from consecutive empty lines
  • Ambiguous prefix hardening: Tightened looksLikeContentLength to require 14+ bytes before matching, preventing false framing detection on short input
  • Closed transport guard: send() now rejects with a clear error when called after close(), with proper write-error propagation

Added

  • Dual-framing MCP transport (CompatibleStdioServerTransport): Auto-detects Content-Length (Codex/OpenCode) and newline-delimited JSON (Cursor/Claude Code) framing on the first message, responds in the same format (#207)
  • Lazy CLI module loading: All CLI subcommands now use createLazyAction() to defer heavy imports (tree-sitter, ONNX, KuzuDB) until invocation, significantly improving gitnexus mcp startup time (#207)
  • Type-safe lazy actions: createLazyAction uses constrained generics to validate export names against module types at compile time
  • Regression test suite: 13 unit tests covering transport framing, security hardening, buffer limits, and lazy action loading

Fixed

  • CALLS edge sourceId alignment: findEnclosingFunctionId now generates IDs with :startLine suffix matching node creation format, fixing process detector finding 0 entry points (#194)
  • LRU cache zero maxSize crash: Guard createASTCache against maxSize=0 when repos have no parseable files (#144)

Changed

  • Transport constructor accepts NodeJS.ReadableStream / NodeJS.WritableStream (widened from concrete ReadStream/WriteStream)
  • processReadBuffer simplified to break on first error instead of stale-buffer retry loop

[1.3.9] - 2026-03-06

Fixed

  • Aligned CALLS edge sourceId with node ID format in parse worker (#194)

[1.3.8] - 2026-03-05

Fixed

  • Force-exit after analyze to prevent KuzuDB native cleanup hang (#192)
