Bump to 3.1.0rc3

zppy rc3

Release process notes:

Step 1: testing

cd ~/ez/zppy
git status
# branch fixes-for-rc3
# nothing to commit
git fetch upstream main
git checkout main
git reset --hard upstream/main
git log
# Last commit: Fixes for rc3 (#753)
# Good, matches https://github.com/E3SM-Project/zppy/commits/main
rm -rf build
lcrc_conda # Activate conda
conda clean --all --y
conda env create -f conda/dev.yml -n zppy-main-20251028
conda activate zppy-main-20251028
python -m pip install .
pytest tests/test_*.py
# 35 passed in 1.13s

We will do full integration testing during the Unified testing.

Step 2: Bump versions

Step 2a: Confluence

Update https://e3sm.atlassian.net/wiki/spaces/DOC/pages/129732419/Packages+in+the+E3SM+Unified+conda+environment:

• E3SM Unified 1.11.0: zppy v3.0.0
• E3SM Unified 1.11.1: zppy v3.0.0
• E3SM Unified 1.12.0: zppy v3.1.0 (We updated this when we made rc1)

Step 2b: zppy repo

cd ~/ez/zppy
git status
# Check for uncommitted changes
git fetch upstream main
git checkout -b v3.1.0rc3 upstream/main
tbump 3.1.0rc3 --no-tag
git log
# Last commit: Bump to 3.1.0rc3
# Creates commit, but doesn't push it (because branch isn't named `main`)
git push upstream v3.1.0rc3
# Follow example of https://github.com/E3SM-Project/zppy/pull/740, https://github.com/E3SM-Project/zppy/pull/750
# Create, add "Update version" label" to, and merge https://github.com/E3SM-Project/zppy/pull/754

git checkout main
git fetch upstream
git reset --hard upstream/main
git tag -a v3.1.0rc3 -m "v3.1.0rc3"
# Delete the branch from the tbump step. Otherwise, the push command won't work.
git branch -D v3.1.0rc3
git push upstream v3.1.0rc3

v3.1.0rc3 now appears on Tags but not on Releases. Good, this is expected.

Step 2c: zppy-feedstock repo

cd ~/zppy-feedstock
curl -sL https://github.com/E3SM-Project/zppy/archive/v3.1.0rc3.tar.gz | openssl sha256
# SHA2-256(stdin)= b350bc2db8cf2fe0e6ea9ae5f7f96351eef116e1338d2948002fca01a62f9e3d
git status
# branch v3.1.0rc2
# nothing to commit
git fetch upstream dev
git checkout -b v3.1.0rc3 upstream/dev
emacs recipe/meta.yaml
# In `recipe/meta.yaml`, update the version and sha256 (and the build number if needed):
# {% set version = "3.1.0rc3" %}
# sha256: ... # The sha256 from the previous step
# number: 0 # build >>> number should always be 0

# Do we need to edit any dependencies?
# Visit https://github.com/E3SM-Project/zppy/compare/v3.1.0rc2...v3.1.0rc3
# There are no changes to conda/ or /.github directories
# So we don't need to change anything here

git add -A
git commit -m "v3.1.0rc3"
git push forsyth2 v3.1.0rc3
# Follow example of https://github.com/conda-forge/zppy-feedstock/pull/27, https://github.com/conda-forge/zppy-feedstock/pull/28
