### What workaround was applied `pyproject.toml`'s `cloudpickle` extra was capped to `cloudpickle>=2.2.1,<3.1.2` (previously unbounded `>=2.2.1`). ### Why This is a workaround for a dependency-resolution deadlock, not a real Airflow bug. Root cause, investigated for #70020: - Airflow's `all` extra includes the `cloudpickle` extra (unbounded floor, no ceiling). - `apache-airflow-providers-snowflake>=6.5.0` requires `snowflake-snowpark-python` on Python >=3.12. - Every released version of `snowflake-snowpark-python` (up to at least 1.53.1) pins `cloudpickle<=3.1.1` in its own metadata. - `cloudpickle==3.1.2` (the latest PyPI release) is incompatible with that cap. - When constraints are generated with `uv ... --resolution highest`, uv tries to satisfy "highest" for both the bare `cloudpickle` extra and the snowflake provider simultaneously. Since they're mutually incompatible at the top, instead of settling on `cloudpickle==3.1.1` (the highest version that still satisfies both), uv's backtracking downgrades `apache-airflow-providers-snowflake` all the way down to `6.4.0` — the last release with no snowpark requirement at all on Python 3.12. This was confirmed by reproducing the resolution directly against the released `constraints-3.3.0` files with `uv pip install`, and by reproducing the fix (capping cloudpickle resolves the conflict and lets `uv` pick the latest snowflake provider release again). ### Follow-up work Remove the `<3.1.2` cap on `cloudpickle` in `pyproject.toml` once `snowflake-snowpark-python` relaxes its own `cloudpickle` pin to allow `>=3.1.2` (or whatever the current cloudpickle release is at that time). ### Acceptance criteria - A released version of `snowflake-snowpark-python` no longer caps `cloudpickle<=3.1.1`. - Regenerating constraints (`breeze release-management generate-constraints`) with the cap removed no longer regresses `apache-airflow-providers-snowflake` to an old version on any supported Python version. ### Related - #70020 (the user-facing symptom: `apache-airflow-providers-snowflake` pinned to a >1-year-old version in the `constraints-3.3.0` files) -- This is an automated message from the Apache Git Service.
