* feat: Add langflow-stepflow package Introduces a new workspace package `src/langflow-stepflow/` that ports the Stepflow integration from the Stepflow repository into the Langflow codebase. The package has two submodules: - `translation/`: translates Langflow flow JSON to Stepflow flow definitions (ported from integrations/langflow/converter/) - `worker/`: a Stepflow worker that executes individual Langflow components via lfx (ported from integrations/langflow/executor/) Entry point: `python -m langflow_stepflow.worker` starts the HTTP worker server for use by a Stepflow orchestrator. No changes to existing Langflow code in this commit. * fix: Address review feedback on langflow-stepflow package - Widen Python version to >=3.10,<3.14 to match langflow-base - Fix import sorting (ruff I001) and unused variable (ruff F841) - Replace sk- prefixed test strings to avoid Gitleaks false positives - Remove placeholder step reference resolution in component_tool (orchestrator resolves these before reaching the worker) - Let exceptions propagate from component_tool_executor instead of returning error dicts that look like successful results - Skip secret/password field defaults in tool input schemas - Use LRU-style bounded cache (128) for compiled components - Use asyncio.to_thread for sync component methods to avoid blocking - Fix mutable NamedTuple default (list→tuple) in PlaceholderGraph - Warn and skip deps with missing field mappings instead of silently falling back to "input" (which overwrites on multiple deps) - Tighten _is_data_list to check __class_name__ == "Data" specifically - Add comment explaining intentional teardown-before-init sequence - Add integration test for example flows * chore: Upgrade to Stepflow SDK 0.12.0 and adapt to lfx 0.3+ renames - Bump stepflow-py and stepflow-orchestrator from >=0.10.0 to >=0.12.0 - Remove Python 3.11 environment markers (SDK now supports 3.10+) - Replace server.run() with gRPC pull transport (run_grpc_worker) matching the upstream stepflow-langflow integration pattern - Update Flow serialization from Pydantic model_dump to msgspec.to_builtins - Remove Pydantic ValueExpr/actual_instance unwrapping (now plain dicts) - Add _langflow_type_name() to map lfx 0.3+ class renames (JSON→Data, Table→DataFrame) back to canonical Langflow type names - Fix DataFrame isinstance checks for lfx Table subclass - Add missing README.md, tests/__init__.py, helpers package - Add skip conditions for missing fixture files * change to lfx schema * [autofix.ci] apply automated fixes * [autofix.ci] apply automated fixes * chore: Align langflow-stepflow ruff config with repo and format - Set line-length = 120 to match root pyproject.toml (was 88, causing conflicts between pre-commit format hook and check hook) - Run ruff format across all source and test files - Add pragma: allowlist secret on test fixtures with fake API keys * [autofix.ci] apply automated fixes * [autofix.ci] apply automated fixes (attempt 2/3) * chore: Rebuild component index * [autofix.ci] apply automated fixes * fix(langflow-stepflow): allow Python 3.14 in requires-python Lift requires-python from <3.14 to <3.15 to match the rest of the workspace and the lockfile. Without this, uv sync on Python 3.14 fails the Unit/LFX/Integration test jobs and the Docker build. * [autofix.ci] apply automated fixes --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> Co-authored-by: ogabrielluiz <gabriel@langflow.org> Co-authored-by: Jordan Frazier <jordan.frazier@datastax.com>
