Add logging functionality

[skasberger]

Add logging functionality to all modules.

Prepare

• [ ] Research
  • [ ] https://docs.python.org/3/library/logging.html
  • [ ] https://docs.python.org/3/howto/logging.html
  • [ ] https://www.youtube.com/watch?v=Pbz1fo7KlGg
  • [ ] https://www.youtube.com/watch?v=p0A4CV4MWd0
  • [ ] https://realpython.com/courses/logging-python/
  • [ ] see Wikipedia-API._query()
• [ ] Which functionality should be logged?
• [ ] Which data should be logged?
• [ ] Should the data be stored? If yes, where and how?
• [ ] Design
  • console outputs should tell better where the code exeution is and what is happening.
    • e.g. Update Dataset 10100 could not be created. to Dataset 10100 could not be created via API.
  • add all exceptions and errors
  • add module to output
  • Logging levels: INFO, WARNING, ERROR
  • use pre-commit plugin
• [ ] Integrate with history functionality #43

Snippets:

import requests
import json

def pretty_print_request(request):
    print( '\n{}\n{}\n\n{}\n\n{}\n'.format(
        '-----------Request----------->',
        request.method + ' ' + request.url,
        '\n'.join('{}: {}'.format(k, v) for k, v in request.headers.items()),
        request.body)
    )

def pretty_print_response(response):
    print('\n{}\n{}\n\n{}\n\n{}\n'.format(
        '<-----------Response-----------',
        'Status code:' + str(response.status_code),
        '\n'.join('{}: {}'.format(k, v) for k, v in response.headers.items()),
        response.text)
    )

def test_post_headers_body_json():
    url = 'https://httpbin.org/post'

    # Additional headers.
    headers = {'Content-Type': 'application/json' }

    # Body
    payload = {'key1': 1, 'key2': 'value2'}

    # convert dict to json by json.dumps() for body data.
    resp = requests.post(url, headers=headers, data=json.dumps(payload,indent=4))

    # Validate response headers and body contents, e.g. status code.
    assert resp.status_code == 200
    resp_body = resp.json()
    assert resp_body['url'] == url

    # print full request and response
    pretty_print_request(resp.request)
    pretty_print_response(resp)

Implementation

• [ ] Define requirements
  • [ ] no console output by default. maybe through argument (part of Api.init()??).
  • [ ]
• [ ] Write tests
• [ ] Write code
• [ ] Update Docs
  • [ ] add to user guide
• [ ] Update Docstrings
• [ ] Run pytest
• [ ] Run tox
• [ ] Run pylint
• [ ] Run mypy

As discussed during the 2024-02-14 meeting of the pyDataverse working group, we are closing old milestones in favor of a new project board at https://github.com/orgs/gdcc/projects/1 and removing issues (like this one) from those old milestones. Please feel free to join the working group! You can find us at https://py.gdcc.io and https://dataverse.zulipchat.com/#narrow/stream/377090-python
