potiuk opened a new pull request, #38764:
URL: https://github.com/apache/airflow/pull/38764
While preparing for presentation about modernizing packaging setup I found
out that we can slightly improve editable installation of airflow. So far we
required a "devel" installation in order to make a working editable
installation of airflow (because the devel extra was installing dependencies
for all the pre-installed providers).
However that required to synchronize the list of providers installed in
`devel` dependency with the list of preinstalled providers, as well as it made
`pip install -e .` resulting with a non-working version of Airflow (because it
requires `fab` provider dependencies to start airflow webserver).
This PR improves it - in editable mode, instead of adding the pre-installed
providers, we add their dependencies. This way we can remove the pre-installed
providers from the list of devel providers to install - because now the
pre-installed provider dependencies are installed simply as "required"
dependencies.
As a result - simple `pip install -e .` should now result in fully working
airflow installation - without all the devel goodies and without celery and
kubernetes dependencies, but fully usable for sequential and local executor
cases.
Also reviewed and updated the comments in hatch_build.py to better reflect
the purpose and behaviour of some of the methods there.
