chore(switchyard): rename plugin distribution by tylersbray · Pull Request #2321 · NVIDIA-NeMo/nemo-helix

tylersbray · 2026-09-23T17:22:34Z

Summary

Rename the in-repo Switchyard middleware distribution to nemo-switchyard-plugin so it no longer collides with upstream PyPI nemo-switchyard. The VirtualModel middleware entry-point name remains nemo-switchyard.

Merge coupling

This packaging PR is tightly coupled with native adapter PR #2325. Merge them back to back: merge this PR first, then immediately merge #2325, which atomically replaces the vendored runtime with nemo-switchyard==0.3.0 and adds the native run_stream host. Do not merge this PR unless #2325 is ready to follow.

Changes

Rename the workspace/plugin distribution while preserving the public middleware key.
Keep the existing nemo-switchyard optional dependency group through deps_group.
Update the generated lock and requirements references.
Add packaging contracts and an isolated distribution-collision smoke test.
Update setup and plugin documentation.

Verification

Pull request title follows the repository's Conventional Commit format
Every commit includes an appropriate Signed-off-by: trailer
uv run pre-commit run -a passes, or any blocked checks are identified below
Targeted tests pass, or tests are marked not applicable above
No secrets, API keys, or credentials are included

Targeted validation:

uv lock --check — passed with uv 0.10.10.
uv run --frozen pytest plugins/nemo-switchyard/tests/test_dist_name.py tools/nemo-helix-sdk-tools/tests/sdk/vendor/test_vendor_package.py -q — 34 passed.
mise exec uv@0.10.10 -- env CI=1 SKIP=helm-docs uv run --frozen pre-commit run -a — passed; Helm docs skipped because this PR does not touch Helm and the local binary is unavailable.
mise exec uv@0.10.11 -- bash plugins/nemo-switchyard/scripts/prove_dist_collision.sh — vendor and upstream 0.3.0 distributions installed side by side in isolated environments.

Summary by CodeRabbit

Updates
- Updated setup and installation guidance to identify the distribution as nemo-switchyard-plugin, distinct from the nemo-switchyard middleware entry point and upstream package.
- Updated workspace and bundled plugin configuration to use the renamed distribution while retaining the existing middleware entry point and dependency group.
Tests
- Added checks for package naming, workspace configuration, and compatibility with the upstream nemo-switchyard package.

📝 Walkthrough

Walkthrough

The Switchyard plugin distribution is renamed to nemo-switchyard-plugin. Workspace and dependency metadata, documentation, and tests use the new distribution name. The nemo-switchyard middleware entry-point name remains unchanged.

Changes

Switchyard distribution rename

Layer / File(s)	Summary
Distribution name and installation references `plugins/nemo-switchyard/pyproject.toml`, `pyproject.toml`, `packages/nemo_helix/pyproject.toml`, `third_party/requirements-main.txt`, `SETUP.md`, `plugins/README.md`, `plugins/nemo-switchyard/README.md`, `plugins/nemo-switchyard/vendor/switchyard/README.md`	The plugin distribution name changes to `nemo-switchyard-plugin` in project, workspace, bundle, and dependency metadata. Documentation identifies `nemo-switchyard` as the middleware entry-point name.
Rename contract checks `plugins/nemo-switchyard/tests/test_dist_name.py`, `plugins/nemo-switchyard/scripts/prove_dist_collision.sh`, `tools/nemo-helix-sdk-tools/tests/sdk/vendor/test_vendor_package.py`	Tests check distribution and entry-point metadata, bundle configuration, and lockfile naming. The integration script checks package versions and imports in isolated environments.
