1. Tmate SSH Debugging:
- Added manual workflow_dispatch trigger with debug_enabled option
- Integrated mxschmitt/action-tmate@v3 for SSH access to CI runner
- Can be triggered manually or by adding [debug] to commit message
- Detached mode with 30min timeout, limited to actor only
- Also triggers on test failure when debug is enabled
2. Enhanced Pytest Output:
- Added --capture=no to see real-time output
- Added --log-cli-level=DEBUG for maximum verbosity
- Added --tb=short for cleaner tracebacks
- Pipe output to tee for both display and logging
- Show last 20 lines of output on completion
3. Environment Diagnostics:
- Export PYTHONUNBUFFERED=1 for immediate output
- Show Python/Pytest versions at start
- Display relevant environment variables
- Check network ports before/after tests
4. Diagnostic Script:
- Created scripts/diagnose_hang.sh for comprehensive system checks
- Shows processes, network, file descriptors, memory, ZMQ status
- Automatically runs on timeout for detailed debugging info
This allows debugging CI hangs via SSH when needed while providing extensive logging by default.
* feat: Add Ollama embedding support for local embedding models
* docs: Add clear documentation for Ollama embedding usage
* fix: remove leann_ask
* docs: remove ollama embedding extra instructions
* simplify MCP interface for Claude Code
- Remove unnecessary search parameters: search_mode, recompute_embeddings, file_types, min_score
- Remove leann_clear tool (not needed for Claude Code workflow)
- Streamline search to only use: query, index_name, top_k, complexity
- Keep core tools: leann_index, leann_search, leann_status, leann_list

* remove leann_index from MCP interface
Users should use CLI command 'leann build' to create indexes first.
MCP now only provides search functionality:
- leann_search: search existing indexes
- leann_status: check index health
- leann_list: list available indexes
This separates index creation (CLI) from search (Claude Code).

* improve CLI with auto project name and .gitignore support
- Make index_name optional, auto-use current directory name
- Read .gitignore patterns and respect them during indexing
- Add _read_gitignore_patterns() to parse .gitignore files
- Add _should_exclude_file() for pattern matching
- Apply exclusion patterns to both PDF and general file processing
- Show helpful messages about gitignore usage
Now users can simply run: leann build
And it will use project name + respect .gitignore patterns.

* feat: Add Ollama embedding support for local embedding models
* docs: Add clear documentation for Ollama embedding usage
* feat: Enhance Ollama embedding with better error handling and concurrent processing
- Add intelligent model validation and suggestions (inspired by OllamaChat)
- Implement concurrent processing for better performance
- Add retry mechanism with timeout handling
- Provide user-friendly error messages with emojis
- Auto-detect and recommend embedding models
- Add text truncation for long texts
- Improve progress bar display logic
* docs: don't mention it in README
- Add 'simulated' to the LLM choices in base_rag_example.py
- Handle simulated case in get_llm_config() method
- This allows tests to use --llm simulated to avoid API costs
- Improve grammar and sentence structure in MCP section
- Add proper markdown image formatting with relative paths
- Optimize mcp_leann.png size (1.3MB -> 224KB)
- Update data description to be more specific about Chinese content
- Add flush=True to all print statements in convert_to_csr.py to prevent buffer deadlock
- Redirect embedding server stdout/stderr to DEVNULL in CI environment (CI=true)
- Fix timeout in embedding_server_manager.stop_server() final wait call
- Remove --no-index so numpy/scipy/etc can be resolved on Python 3.13
- Keep --find-links to force our packages from local dist
Fixes: dependency resolution failure on Ubuntu Python 3.13 (numpy missing)
- Build leann-core and leann on macOS too
- Install all packages via --find-links and --no-index across platforms
- Lower macOS MACOSX_DEPLOYMENT_TARGET to 12.0 for wider compatibility
This ensures consistency and avoids PyPI drift while improving macOS compatibility.
- Replace 'int | None' with 'Optional[int]' everywhere
- Replace 'subprocess.Popen | None' with 'Optional[subprocess.Popen]'
- Add Optional import to all affected files
- Update ruff target-version from py310 to py39
- The '|' syntax for Union types was introduced in Python 3.10 (PEP 604)
Fixes TypeError: unsupported operand type(s) for |: 'type' and 'NoneType'
- Ubuntu: Install all packages from local builds with --no-index
- macOS: Install core packages from PyPI, backends from local builds
- Remove --no-index for macOS backend installation to allow dependency resolution
- Pin versions when installing from PyPI to ensure consistency
Fixes error: 'leann-core was not found in the provided package locations'
- Explicitly specify Python version when creating venv with uv
- Prevents mismatch between build Python (e.g., 3.10) and test Python
- Fixes: _diskannpy.cpython-310-x86_64-linux-gnu.so in Python 3.11 error
The issue: uv venv was defaulting to Python 3.11 regardless of matrix version
- Use --find-links with --no-index to let uv select correct wheel
- Prevents installing wrong Python version wheel (e.g., cp310 for Python 3.11)
- Fixes ImportError: _diskannpy.cpython-310-x86_64-linux-gnu.so in Python 3.11
The issue was that *.whl glob matched all Python versions, causing
uv to potentially install a cp310 wheel in a Python 3.11 environment.
- Remove '--plat linux_x86_64' which is not a valid platform tag
- Let auditwheel automatically determine the correct platform
- Based on CI output, it will use manylinux_2_35_x86_64
This was causing auditwheel repair to fail, preventing proper wheel repair
- Check wheel contents before and after auditwheel repair
- Verify _diskannpy module installation after pip install
- List installed package directory structure
- Add explicit platform tag for auditwheel repair
This helps diagnose why ImportError: cannot import name '_diskannpy' occurs
- Change from --find-links to direct wheel installation with --force-reinstall
- This ensures CI uses locally built packages with latest source code
- Prevents uv from using PyPI packages with same version number but old code
- Fixes CI test failures where old code (without metadata_file_path) was used
Root cause: CI was installing leann-backend-diskann v0.2.1 from PyPI
instead of the locally built wheel with same version number.
- Add logging in DiskANN embedding server to show metadata_file_path
- Add debug logging in PassageManager to trace path resolution
- This will help identify why CI fails to find passage files
- Pin ruff==0.12.7 in pyproject.toml dev dependencies
- Update CI to use exact ruff version instead of latest
- Add comments explaining version pinning rationale
- Ensures consistent formatting across local, CI, and pre-commit
