potiuk opened a new pull request, #48495:
URL: https://github.com/apache/airflow/pull/48495
The source providers and old airflow did not work well together for a few
reasons:
* airflow 2 did not have legacy namespace packaging specification at the top
of the file
* the providers and commong __init__.py files had no legacy namespace
specification
* few Airflow 3-only providers cause airflow 2 to fail when installed
together from sources.
* AIRFLOW__CORE__AUTH_MANAGER was set pointing to Simple Auth Manger only
used in Airflow 3
This PR fixes all issues:
* it patches installed airflow (if airflow 2 is installed) and fixes the
__init__.py files
* it uninstalls the providers that are problematic
* it unsets the AIRFLOW__CORE__AUTH_MANAGER variable
