v1.4.6

Highlights

Phase 7 type resolution ships return-aware loop inference: for-loop iterables like for (const u of getUsers()) now resolve element types via function return types across 8 languages. PHP gets class-property iterable support for foreach($this->property) patterns.

---

Type Resolution (Phase 7)

• Phase 7.1–7.2 — ReturnTypeLookup interface + ForLoopExtractorContext context object + dormant pendingCallResults infrastructure (#341)
• Phase 7.3 — Call-expression iterable resolution for TS/JS, Java, Kotlin, C#, Go, Rust, Python, PHP (#341)
• Phase 7.4 — PHP $this->property foreach via @var class property scan (#341)
• Phase 7.5 — PHP function_call_expression / member_call_expression foreach (#341)
• extractReturnTypeName deduplicated from call-processor.ts into shared.ts (137 lines removed)

v1.4.5

Highlights

This release brings a major type resolution overhaul (Phases 4–6), Ruby language support, a database migration from KuzuDB to LadybugDB, and significant performance optimizations to the ingestion pipeline.

---

Type Resolution System (Phases 4–6)

The type resolution pipeline now covers 12 languages with deep support for receiver-constrained call resolution:

• Phase 4 — Nullable unwrapping, for-loop element typing, assignment chain propagation (#310)
• Phase 5 — Chained method calls, pattern matching, class-as-receiver dispatch (#315)
• Phase 6 — Container descriptors (Map keys vs values), recursive pattern binding (C# is, Kotlin when/is), for-loop Tier 1c across all languages (#318)
  • C# nested member foreach (this.data.Values)
  • C++ pointer dereference range-for (*usersPtr)
  • Java this.data.values() field access
  • PHP $this->property foreach member access
  • Position-indexed branch-local narrowing for Kotlin smart casts

Performance Optimizations

• Worker pool threshold — skip thread pool for small repos (<15 files or <512KB), saving 100–400ms
• AST walk pruning — SKIP_SUBTREE_TYPES skips leaf-only subtrees (strings, comments, literals)
• Pre-computed interestingNodeTypes — single Set.has() replaces 3 checks per AST node
• fastStripNullable — fast-path nullable check for simple identifiers (90%+ of lookups)
• extractFunctionName refactor — replace .children?.find() with manual for loops to eliminate array allocations
• skipGraphPhases pipeline option — skip MRO/community/process phases for faster test runs

New Features

• Ruby language support for CLI and web (#111) by @candidosales
• TypeEnvironment API with constructor inference, self/this/super/base/parent resolution (#274)
• Return type inference with JSDoc, PHPDoc, and YARD doc-comment parsing (#284)
• .gitignore and .gitnexusignore support during file discovery (#231) by @ivkond and @jecanore
• Codex MCP configuration documentation (#236) by @ZakAnun
• Type resolution system documentation with architecture guide and roadmap

Infrastructure

• Migrated from KuzuDB to LadybugDB v0.15 (#275) by @candidosales
• hookTimeout: 120000 in vitest config for CI reliability

Bug Fixes

• Same-directory Python import resolution (#328) by @cnighut
• Ruby method-level call resolution, HAS_METHOD edges, and dispatch table (#278)
• Dynamic agent skill discovery and installation in CLI (#270) by @cnighut
• Template string incorrectly included in AST pruning set (contains interpolated expressions)

v1.4.0

What's New

Language-Aware Code Intelligence Engine (#238)

A full symbol resolution engine with 3-tier resolver, Method Resolution Order (MRO), constructor/struct literal resolution, receiver-constrained disambiguation, and heritage/ownership edges across 9 languages.

• 3-tier resolver: exact FQN → scope-walk → guarded fuzzy (refuses ambiguous matches)
• MRO: C++ leftmost-base, C#/Java class-over-interface, Python C3, Rust qualified syntax
• Constructor resolution: new Foo(), User{...}, C# primary constructors, target-typed new
• Receiver-constrained: per-file TypeEnv disambiguates user.save() vs repo.save()
• Heritage edges: HAS_METHOD, OVERRIDES, Go struct embedding, Swift extensions
• Modular architecture: resolvers/, type-extractors/, language-config.ts, dispatch tables with Record<SupportedLanguages, Handler> + satisfies
• 178 integration resolver tests across 9 languages, 1146 total tests passing

Skill Generation (#171)

Optional AI agent skill generation from the knowledge graph via npx gitnexus analyze --skills.

C/C++/C#/Rust Language Support (#237)

Consolidated fixes from 6 community PRs — .h → C++ mapping, sibling-based modifier scanning, adaptive buffer sizing, expanded entry point patterns, call expression matching.

v1.3.11

What's Changed

🚨 Security

• test: add integration test coverage and fix KuzuDB fork crashes by @magyargergo in #209

🚀 Features

• feat(hooks): auto-reindex after git commit with embeddings preservation by @L1nusB in #205

👷 CI/CD

• ci: add macOS to cross-platform test matrix by @magyargergo in #208

Full Changelog: v1.3.10...v1.3.11

v1.3.10

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 and newline-delimited JSON 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 types)
• processReadBuffer simplified to break on first error instead of stale-buffer retry loop
