Thanks for pointing this out.

I’ve created a DISCUSS thread on the dev@airflow.apache.org mailing list for the new IBM Db2 provider, following the ACCEPTING_PROVIDERS.rst process.

uv.lock on main just moved via #70652 ("Review and update constraint dependencies"), commit 443b919 and this PR currently conflicts.

Quickest fix:

git fetch upstream main && git rebase upstream/main
rm uv.lock && uv lock
git add uv.lock && git rebase --continue
git push --force-with-lease

Automated nudge — ignore if you're not ready to rebase. This comment is updated in place on future uv.lock bumps.

Was there a mailing list thread about this new provider?
https://github.com/apache/airflow/blob/main/providers/ACCEPTING_PROVIDERS.rst#examples-of-current-process

- Change conn_type to 'ibmdb2' and conn_name_attr to 'conn_id' - Add type hint for get_conn() return value - Fix: Skip None values in connection strings

Move example DAG to tests/system/ibm/db2/ and update provider metadata to not-ready/incubation/0.1.0

Add dialects docs and clean up __init__.py files.

Thank you David.

Provider is looking good now, thanks for the work and changes.

I think you should start a vote now for this provider on the Apache Airflow devlist if the provider was already proposed there, if not you should start a proposal first before starting a vote.

https://lists.apache.org/list.html?dev@airflow.apache.org

Once the provider has been approved, then we can merge.
