From ea6d3d744885c23f9fd6eb3bb0e5eb12fb089526 Mon Sep 17 00:00:00 2001 From: Brendan Collins Date: Thu, 21 May 2026 19:41:37 -0700 Subject: [PATCH 1/4] Add CI workflow that runs geotiff golden_corpus with rasterio from conda-forge (#2289) Every golden_corpus test under xrspatial/geotiff/tests/ starts with `pytest.importorskip("rasterio")`, so the existing pip-based job in test.yml silently skips the entire parity oracle. This adds a second workflow that installs rasterio + GDAL from conda-forge via mamba-org/setup-micromamba and runs the geotiff test directory. PR triggers run ubuntu-only on the fast lane (`-m "not slow"`); push-to-main and the nightly cron run the full matrix and full set. --- .github/workflows/test-geotiff-corpus.yml | 75 +++++++++++++++++++++++ 1 file changed, 75 insertions(+) create mode 100644 .github/workflows/test-geotiff-corpus.yml diff --git a/.github/workflows/test-geotiff-corpus.yml b/.github/workflows/test-geotiff-corpus.yml new file mode 100644 index 000000000..ea8fb9d22 --- /dev/null +++ b/.github/workflows/test-geotiff-corpus.yml @@ -0,0 +1,75 @@ +name: pytest-geotiff-corpus +on: + push: + branches: + - main + pull_request: + branches: + - '*' + # Nightly cron so the full corpus (slow lane included) runs at + # least once a day against rasterio from conda-forge.

Broader geotiff integration tests stay on the existing `test.yml` job. - Add a verification step that re-imports `rasterio` and `numpy` after `pip install -e .[tests]`. If pip pulls PyPI wheels on top of the conda-forge env and breaks the GDAL/proj link, this fails the build with a clear message instead of mid-pytest. - Drop the unused `env: OS / PYTHON` block carried over from `test.yml`. --- .github/workflows/test-geotiff-corpus.yml | 17 ++++++++++------- 1 file changed, 10 insertions(+), 7 deletions(-) diff --git a/.github/workflows/test-geotiff-corpus.yml b/.github/workflows/test-geotiff-corpus.yml index ea8fb9d22..bbec23d23 100644 --- a/.github/workflows/test-geotiff-corpus.yml +++ b/.github/workflows/test-geotiff-corpus.yml @@ -33,9 +33,6 @@ jobs: matrix: os: ${{ github.event_name == 'pull_request' && fromJson('["ubuntu-latest"]') || fromJson('["ubuntu-latest", "macos-latest", "windows-latest"]') }} python: ${{ github.event_name == 'pull_request' && fromJson('["3.14"]') || fromJson('["3.12", "3.14"]') }} - env: - OS: ${{ matrix.os }} - PYTHON: ${{ matrix.python }} defaults: run: # `-el` so micromamba's activation hooks fire and `rasterio` @@ -61,15 +58,21 @@ jobs: run: | python -m pip install --upgrade pip pip install -e .[tests] - - name: Show rasterio / GDAL versions + - name: Verify rasterio still imports after pip step + # `pip install -e .[tests]` can pull PyPI wheels (pyproj, numpy) on + # top of the conda-forge env and shadow the GDAL/proj stack that + # rasterio links against.

The committed bytes were produced against a particular GDAL / libjpeg, and conda-forge ships different versions today, so the COG-with-overview and JPEG- YCbCr fixtures drift. The oracle and nodata tests still run; they compare semantic content, which is what this workflow actually wants to verify. Follow-up tracked in #2299 to make the determinism check toolchain- agnostic so this `--ignore` can be removed. --- .github/workflows/test-geotiff-corpus.yml | 14 ++++++++++++-- 1 file changed, 12 insertions(+), 2 deletions(-) diff --git a/.github/workflows/test-geotiff-corpus.yml b/.github/workflows/test-geotiff-corpus.yml index 19ee38ac7..8451ce3a7 100644 --- a/.github/workflows/test-geotiff-corpus.yml +++ b/.github/workflows/test-geotiff-corpus.yml @@ -72,8 +72,18 @@ jobs: # push-to-main and the nightly schedule run the full set. # Target is scoped to `golden_corpus/` to match the issue (#2289); # broader geotiff integration tests stay on the `test.yml` job. + # + # `test_corpus_determinism.py` is deselected here: it asserts md5 + # equality between committed fixtures and bytes regenerated by + # `generate.py`, which depends on the exact GDAL / libjpeg the + # corpus was produced against.
