Fixes #1152

/rest/v1/ma_job_results returns a 500 on opencre.org whether or not you pass an id:

$ curl -s -o /dev/null -w '%{http_code}\n' 'https://opencre.org/rest/v1/ma_job_results?id=foo'
500
$ curl -s -o /dev/null -w '%{http_code}\n' 'https://opencre.org/rest/v1/ma_job_results'
500

There were two problems in fetch_job.

Redis down. The function already tries to return a 503 when the job queue is unavailable, but that except only wrapped redis.connect(). redis-py doesn't open a socket until the first command, so connect() never fails, and the real error came from Job.fetch() on the next line. Redis is also read after the fetch (get_status(), latest_result(), conn.exists), so I added a blueprint errorhandler(RedisError) that logs the error and returns a plain 503. That covers all of those calls, and fetch_job only needs to handle NoSuchJobError itself. The old response also put the exception text in the body, which included the Redis host and port. That's gone now.

No id. Job.fetch(id=None) raises a TypeError. The OpenAPI spec already marks id as required, so this now returns a 400 before touching Redis.

I added 400 and 503 to the route's extra_responses and regenerated docs/api/openapi.yaml with scripts/generate_openapi.py.

Tests

There were no tests for this route before. I added four to web_main_test.py:

• missing id returns 400
• REDIS_URL pointing at a closed local port returns 503, and the address doesn't show up in the body (no mocks, so it goes through the real connection)
• Redis failing after Job.fetch succeeds, in get_status(), also returns 503
• NoSuchJobError still returns 404

The missing-id and closed-port tests fail on main with the same TypeError and ConnectionError as in the issue, and all four pass with the change.

$ python -m unittest application.tests.web_main_test
Ran 59 tests
OK

$ python scripts/check_openapi_guardrail.py
OPENAPI_GUARDRAIL_OK:
  - documented views OK
  - spec freshness OK
  - spec validity OK
  - route coverage OK

$ black --check .
358 files would be left unchanged.

I also ran the full suite on this branch and on main, and both fail the same set. Those failures are all modules missing from my local env (bs4, git, mcp, xmltodict, gspread) plus a few Windows path tests. The frontend poller in GapAnalysis.tsx always sends an id and handles any error status the same way in its catch, so nothing changes on that side.

Summary by CodeRabbit

• Bug Fixes

  • Requests for job results return an error when the required ID is missing.
  • Job queue connection failures return a generic service-unavailable response without exposing connection details.
  • Unknown job IDs return a not-found response.

• Documentation

  • Updated API documentation to describe missing-ID and unavailable-service responses.

Walkthrough

The job-results endpoint now validates the id parameter and returns a generic 503 response for Redis errors. Tests and API documentation cover missing IDs, Redis errors, and unknown jobs.

Changes

Job results endpoint

Layer / File(s)	Summary
Validate and handle job-result requests application/web/web_main.py, application/tests/web_main_test.py, application/web/openapi_registry.py, docs/api/openapi.yaml	fetch_job returns 400 when id is missing and 404 for an unknown job. A Redis error handler logs Redis errors and returns a generic 503 response. Tests and both OpenAPI definitions cover the documented responses.

Review comments at @application/tests/web_main_test.py:
- Around line 1183-1184: Update test_ma_job_results_redis_unreachable to remove
the mocks for Job.fetch and app_redis.connect, and temporarily configure an
unreachable loopback Redis endpoint while clearing host and port overrides. Keep
the assertions that the route returns 503 and does not expose the Redis port.

Review comments at @application/web/web_main.py:
- Line 508: In the `Job.fetch()` error-handling block, replace the broad
`Exception` catch with the specific Redis connection failure type or types the
queue client can raise. Keep the 503 “Job queue unavailable” handling for those
failures, and let unrelated errors follow the existing unexpected-error path.
- Around line 508-510: Add a Redis-client-specific exception handler around the
later `conn.exists(standards_hash)` operation in the finished-job path for
multiple results, returning 503 when Redis is unavailable. Keep unrelated
programming errors uncaught, and leave the existing `Job.fetch()` handling
unchanged.
