From 37733726b69ddd610b628e0892c3199136e4f3d5 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/2] fix: comprehensive test coverage and 5 bug fixes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bug fixes:
- Markdownify.get(): use resolvedPath for existsSync/readFile (relative paths were silently broken)
- isWithinDirectory: fix prefix false-positive matching (e.g. /docs-other matched /docs)
- validateUrl: block IPv6 loopback (::1) and embedded credentials (user:pass@host)
- inferExtensionFromUrl: handle query strings and fragments before extension check
- isMarkdownFile: case-insensitive extension matching (.MD, .MARKDOWN)

Test improvements:
- Added server.test.ts: 17 MCP protocol integration tests (routing, errors, response format)
- Added tools.test.ts: 15 tool schema validation tests
- Added Markdownify.extended.test.ts: 16 edge case tests (redirects, injection, path restrictions)
- Extended utils.test.ts: +12 tests (IPv6, credentials, prefix boundaries, case sensitivity)
- Fixed test timeouts: PDF 15s (onnxruntime warmup), invalid-repo 120s (GitHub API latency)

Test count: 79 → 142 tests, 105 → 422 expectations

+# Markdownify MCP Server — Environment Variables
+# ============================================
+# Copy this file to .env and adjust as needed.
+# All variables are optional with sensible defaults.
+
+# --- Executable Paths ---
+# Override the path to the `markitdown` Python CLI.
+# Default: .venv/bin/markitdown (project venv) → "markitdown" on PATH
+# MARKITDOWN_PATH=/opt/markitdown/bin/markitdown
+
+# Override the path to the `repomix` Node.js CLI.
+# Default: node_modules/.bin/repomix → "repomix" on PATH
+# REPOMIX_PATH=/opt/repomix/bin/repomix
+
+# --- Security: File Access Control ---
+# Semicolon-separated list (Windows) or colon-separated list (macOS/Linux)
+# of directories that the server is allowed to read files from.
+#
+# When set, filePath arguments outside these directories are rejected.
+# When UNset, file access is UNRESTRICTED — USE WITH CAUTION.
+#
+# Examples:
+#   macOS/Linux:   MD_ALLOWED_PATHS=/home/user/docs:/tmp/shared
+#   Windows:       MD_ALLOWED_PATHS=C:\Users\user\docs;D:\shared
+# MD_ALLOWED_PATHS=
+
+# Deprecated: Single-directory alias for MD_ALLOWED_PATHS.
+# Prefer MD_ALLOWED_PATHS for multi-directory support.
+# MD_SHARE_DIR=

+# Changelog
+
+## [Unreleased]
+
+### Fixed
+- `Markdownify.get()` now correctly resolves relative paths and home directory (`~`) paths. Previously the resolved path was computed but never used, causing `existsSync` and `readFile` to operate on the raw input.
+- `isWithinDirectory()` no longer produces false positives for prefix matches (e.g. `/home/user/docs-other` matching `/home/user/docs`).
+- `validateUrl()` now blocks IPv6 loopback addresses (`::1`) and rejects URLs with embedded credentials (`user:pass@host`).
+- `inferExtensionFromUrl()` now correctly handles URLs with query strings and fragments before checking file extension.
+- `isMarkdownFile()` now matches extensions case-insensitively (`.MD`, `.MARKDOWN`).
+
+### Changed
+- Increased test timeouts for PDF conversion (15s, onnxruntime warmup) and invalid repo detection (120s, GitHub API latency).
+
+### Added
+- `server.test.ts`: 17 MCP protocol integration tests covering tool listing, routing dispatch, argument validation, error formatting, and response structure.
+- `tools.test.ts`: 15 tool schema validation tests for naming conventions, required fields, and annotation consistency.
+- `Markdownify.extended.test.ts`: 16 edge case tests for redirect handling, command injection defense, path allowlist enforcement, and error message quality.
+- Extended `utils.test.ts` with 12 additional tests for IPv6 security, credential injection, path boundary edge cases, and URL query/fragment handling.
+- `.env.example` with documentation for all supported environment variables.
+
+## [1.1.0] — 2025-05
+
+### Added
+- Docker path resolution: `MARKITDOWN_PATH`, `REPOMIX_PATH`, and `MD_ALLOWED_PATHS` environment variables are now overridable inside containers.
+- Docker E2E smoke test via `scripts/docker-smoke-test.sh`.
+
+### Fixed
+- Dockerfile: use `markitdown[pdf]` instead of `[all]` to avoid ONNX runtime ARM compatibility issues.
+
+## [1.0.4] — 2025-04
+
+### Added
+- GitHub Actions CI workflow with `lint → build → test` pipeline (on `ci/add-biome-and-github-actions` branch).
+- Biome configuration for linting and formatting.
+
+## [1.0.3] — 2025-04
+
+### Fixed
+- Dockerfile and `pyproject.toml` updated to use `markitdown[all]` for complete format support.
+- CI: added Python setup step for markitdown tests.
+- CI: ignore harmless stderr warnings from markitdown subprocess.
+
+## [1.0.2] — 2025-04
+
+### Fixed
+- Missing `test.pdf` sample data file added.
+- `CLAUDE.md` project documentation added.
+
+## [1.0.1] — 2025-04
+
+### Added
+- Initial public release.
+- 11 MCP tools for file-to-markdown conversion.
+- SSRF protection with `private-ip` library and redirect validation.
+- Path allowlist security (`MD_ALLOWED_PATHS` / `MD_SHARE_DIR`).
+- `git-repo-to-markdown` tool wrapping Repomix.
+- Docker multi-stage build support.
+- 30+ unit tests and 14 integration tests.
