feat: support feed stable ids as request parameter in the GBFS validator batch function

[davidgamez]

Summary:

This pull request enhances the gbfs_validator_batch function to support processing specific feeds based on a POST request with feed stable IDs, improves error handling, and adds corresponding unit tests. The most important changes include modifying the function signature, adding logic to handle feed IDs, introducing a helper function for fetching feeds by ID, and creating a new test case.

Enhancements to gbfs_validator_batch function:

• Updated the function signature to accept a request parameter, enabling the function to process POST requests with a JSON body containing feed_ids. This allows selective feed processing or fallback to processing all feeds if no feed IDs are provided. (functions-python/gbfs_validator/src/main.py, [1] [2]
• Added error handling for invalid or missing request bodies, ensuring the function gracefully handles malformed inputs. (functions-python/gbfs_validator/src/main.py, functions-python/gbfs_validator/src/main.pyL116-R133)

New helper function:

• Introduced fetch_gbfs_feeds_by_stable_ids to query and retrieve GBFS feeds by their IDs, filtering out deprecated feeds. This modularizes the logic for feed retrieval by ID. (functions-python/gbfs_validator/src/main.py, functions-python/gbfs_validator/src/main.pyR169-R178)

Unit test additions:

• Added a new test case, test_gbfs_validator_batch_by_feed_ids, to validate the behavior of the gbfs_validator_batch function when processing specific feed IDs. This test ensures proper handling of POST requests, feed retrieval, and publishing logic. (functions-python/gbfs_validator/tests/test_gbfs_validator.py, functions-python/gbfs_validator/tests/test_gbfs_validator.pyR182-R218)

Summary generated by our AI friend

Expected behavior:

When the batch function receives the feed_ids field in the post body, it only publishes events for the listed ids; otherwise, it will publish the events for all GBFS ids.

Testing tips:

(Internal team only)Deployed to DEV, this function can be tested by sending the command:

curl -X POST "https://gbfs-validator-batch-978785769226.northamerica-northeast1.run.app" \
-H "Authorization: bearer $(gcloud auth print-identity-token)" \
-H "Content-Type: application/json" \
-d '{
  "feed_stable_ids": [ "gbfs-lyon" ]
}'
