Replace setuptools with uv build backend and add Python 3.13 support

[devin-ai-integration]

Summary

Replace setuptools with uv_build as the build backend and pin snowflake-snowpark-python>=1.35.0 to fix the pkg_resources removal in setuptools 82.0.0.

Problem

setuptools 82.0.0 (released 2026-02-08) removed the pkg_resources module. This broke all DataApps using keboola_streamlit because snowflake-snowpark-python (older versions) internally imports pkg_resources at runtime. Customers hit ModuleNotFoundError: No module named 'pkg_resources' on app rebuild without any changes on their side.

Relates to: AJDA-2244 / SUPPORT-15269

Changes

Build backend migration (pyproject.toml):

• Replaced setuptools with uv_build>=0.10.3,<0.11.0 as the build backend (zero-config, auto-discovers src/ layout)
• Removed [tool.setuptools.*] sections (not needed with uv)
• Aligns with keboola/python-component

Runtime fix (pyproject.toml):

• Pinned snowflake-snowpark-python>=1.35.0 — this version no longer imports pkg_resources, which is the actual fix for the customer-facing error

Dependency locking (pyproject.toml, uv.lock, requirements.txt):

• Removed requirements.txt — dependencies are now fully declared in pyproject.toml
• Added [dependency-groups] with dev = ["pytest", "pre-commit"]
• Generated uv.lock for reproducible installs
• CI uses uv sync (single step) instead of separate pip install calls

CI pipeline (.github/workflows/publish.yml):

• Switched to uv throughout: uv sync for deps, uv run for pre-commit/pytest, uv build for packaging, uv publish for PyPI
• Replaced build + twine with native uv build / uv publish
• Added astral-sh/setup-uv@v7 alongside actions/setup-python@v5
• CI matrix for Python 3.10 and 3.13
• Smoke test uses uv run --isolated --with dist/*.whl for clean validation

Python version support:

• Dropped Python 3.9 (EOL), minimum is now >=3.10
• Added Python 3.10–3.13 to supported classifiers and CI matrix

Test plan

• CI passes on both Python 3.10 and 3.13
• Smoke test builds wheel and successfully imports KeboolaStreamlit in isolated env
• Publish job uses uv build + uv publish with existing PyPI credentials
• After release: customer can upgrade keboola_streamlit and remove setuptools<82.0.0 workaround

Review & Testing Checklist for Human

• Verify PyPI publish works with uv publish: The publish job now uses UV_PUBLISH_USERNAME / UV_PUBLISH_PASSWORD env vars (mapped from existing PYPI_USERNAME / PYPI_API_TOKEN secrets) instead of TWINE_USERNAME / TWINE_PASSWORD. This path only runs on tagged releases, so it has not been exercised by CI on this branch. Consider a dry-run build before the first tagged release.
• Verify wheel contents: Run uv build --wheel && unzip -l dist/*.whl locally and confirm all expected source files from src/keboola_streamlit/ are present. The uv_build backend auto-discovers the src/ layout, replacing the explicit setuptools config.
• Test real usage on Python 3.13: The smoke test only validates import. Verify actual Snowflake session creation and kbcstorage client calls work in a Python 3.13 environment.
• Confirm requires-python >=3.10 is acceptable: Python 3.9 is EOL, but check if any existing users/deployments still rely on 3.8/3.9.

Suggested test plan: Install from this branch into clean Python 3.10 and 3.13 venvs (pip install git+https://github.com/keboola/keboola_streamlit@devin/1770666055-replace-pkg-resources-python313), then run from keboola_streamlit import KeboolaStreamlit and the existing pytest suite in both.

Notes

• snowflake-snowpark-python 1.35.0+ supports Python 3.13 (requires-python: <3.14,>=3.9); versions ≤1.34.0 excluded it (<3.13).
• The version = "v0.1.3" in pyproject.toml has a leading v which is not strictly PEP 440 compliant. This was pre-existing and not changed in this PR; uv_build appears to handle it, but worth noting.

Pull request overview

This PR updates the project’s Python packaging and CI configuration to support Python 3.13 by switching the build backend from setuptools to hatchling, tightening dependency compatibility for Snowpark, and updating the publish workflow to run on Python 3.13.

Changes:

• Switched build backend to hatchling and configured wheel packaging.
• Bumped requires-python to >=3.9, added Python 3.9–3.13 classifiers, and pinned snowflake-snowpark-python>=1.35.0.
• Updated GitHub Actions workflow to use newer action versions and Python 3.13, and adjusted publish dependencies accordingly.

File	Description
pyproject.toml	Migrates build backend to hatchling, updates supported Python versions/classifiers, and pins Snowpark for 3.13 compatibility.

pyproject.toml:7

• version = "v0.1.3" is not PEP 440–compliant (the leading v is invalid in core metadata) and may cause hatchling/packaging to reject the build. Consider changing the project version to 0.1.3 (keep the v prefix only for git tags/releases).

build-backend = "hatchling.build"

.github/workflows/publish.yml:24

• The workflow installs dependencies from requirements.txt, which still allows older snowflake-snowpark-python versions on Python 3.10 even though the package metadata now requires snowflake-snowpark-python>=1.35.0. To ensure CI matches what users get from PyPI, either pin the requirement in requirements.txt as well or install the project (e.g., pip install -e .) so dependencies are resolved from pyproject.toml.

        run: |
          python -m pip install --upgrade pip
          pip install -r requirements.txt
          pip install pytest pre-commit

I'd really appreaciate a couple more changes, but as this ticket is close to (or already) breaching SLA, I approve this now 🙏

[soustruh]

Nice, everything looks OK now! 🎉
