Update Python Client to 3.0.1

[kaxil]

This brings in the new Airflow API v2 to the Python client

As part of this change the following breaking changes have occurred:

• The API returns 422 status code instead of 400 for validation errors.

  For instance when the request payload, path params, or query params are invalid.

• When listing a resource for instance on GET /dags, fields parameter is not supported anymore to obtain a partial response.

  The full objects will be returned by the endpoint. This feature might be added back in upcoming 3.x versions.

• Passing list in query parameters switched from form, non exploded to form, exploded i.e before ?my_list=item1,item2 now ?my_list=item1&my_list=item2

• execution_date was deprecated and has been removed. Any payload or parameter mentioning this field has been removed.

• Datetime format are RFC3339-compliant in FastAPI, more permissive than ISO8601, meaning that the API returns zulu datetime for responses, more info here Why do the generated docs use Z-terminated ISO strings when python doesn't? fastapi/fastapi#7693 (comment). Both Z and 00+xx are supported for payload and params.

  This is due FastAPI and pydantic v2 default behavior.

• PATCH on DagRun and TaskInstance are more generic and allow in addition to update the resource state and the note content.

  Therefore the two legacy dedicated endpoints to update a DagRun note and TaskInstance note have been removed.

  Same for the set task instance state, it is now handled by the broader PATCH on task instances.

• assets/queuedEvent endpoints have moved to assets/queuedEvents for consistency.

• dag_parsing endpoint now returns a 409 when the DagPriorityParsingRequest already exists. It was returning 201 before.

• clearTaskInstances endpoint default value for reset_dag_runs field has been updated from False to True.

• Pool name can't be modified in the PATCH pool endpoint anymore. Pool name shouldn't be updated via pool PATCH API call.

• Logical date is now a nullable. In addition it is a nullable required payload field for Triggering a DagRun endpoint.

Just one comment @kaxil -> You know we are using this repo just to keep archive of generated code and releasing is done directly from airflow repo? Just want to make sure that you have not missed that part while you were not doing releases

You need to increase Python version to 3.9 - the error is due to Python 3.8 still used.

Yup :)

ah, thanks

Nice thanks, just one question.

Nice, I was able to successfully run test_python_client.py against my breeze API.

At some point we might want to rewrite it because it's not runnable in this current state. (pytest is missing from deps, generate_access_token is actually coming from airflow core, so you have to vendor this in to be able to actually run it, which shouldn't be needed.)

Agreed
