Pull request overview

This PR prepares the Hamilton sub-packages (SDK/UI/LSP/Contrib) for release under the Apache package names by adding “redirect” packages for legacy sf-hamilton-* names, updating compatibility for newer dependency versions (e.g., pygls>=2.0, polars>=1.34), and adjusting UI mini-mode static asset handling.

Changes:

Add sf-hamilton-{sdk,ui,lsp,contrib} redirect package skeletons (README + templated pyproject + build scripts).
Fix/relax tests for optional dependencies (skip when missing) and for dependency behavior changes (Polars date quantiles, UI build path string checks).
Update UI mini settings to use Vite’s build/assets/ output and adjust LSP to remove deprecated loop usage for pygls>=2.0.

+# Step 1: Open the UI in your browser and create a project.
+# The `hamilton ui` command opens http://localhost:8242 automatically.
+# Create a project and note its ID (shown in the URL, e.g. /dashboard/project/1).

+cd examples/hamilton_ui
+pip install -r requirements.txt
+python run.py --username <your_username> --project-id <project_id>
+# Expected: "Captured execution run. Results can be found at ..."

+# Step 3: Verify in the UI
+# Navigate to http://localhost:8242/dashboard/project/<id>/runs

Do we need a regression test for this?

Wouldn't it be better to have a script that reads the versions from wherever they're stored (like on L45 below)? Fewer manual steps = fewer opportunities for human error.

+python -m venv /tmp/verify-sdk && source /tmp/verify-sdk/bin/activate
+pip install apache-hamilton apache-hamilton-sdk==${SDK_VERSION}


Shouldn't we use uv for such things?

Dev-iL · 2026-05-18T06:48:46Z

+pip install -r requirements.txt -r requirements-test.txt
+pip install -e .


Didn't we remove requirement txts? I think we should install with uv sync --group test

+hamilton ui --settings-file mini --no-open --port 8241 &
+# Or equivalently from the CLI:
+# python -m hamilton.cli ui --settings-file mini --no-open --port 8241


uv run migrate-ui could be nice

+        actual_q = actual["observability_value"][col].pop("quantiles")
+        expected_q = expected_stats["observability_value"][col].pop("quantiles")
+        # Accept either empty or populated quantiles for Date columns
+        assert actual_q == expected_q or actual_q == {}


Perhaps we should branch on the polars version to avoid a false pass? This might even be doable as a test parameterization.

Would it be that bad to set the minimum pyarrow version to 14.0.1 (released on Nov 2023) to avoid pyarrow_hotfix entirely?
