Description

When MediaRequestSubscriber cannot resolve the server for a request due to the server being deleted or no default for that category being set, it now sets the request to `FAILED` instead of `PROCESSING`. Previously, the request would be marked as `PROCESSING` and fail silently. Admins were not alerted and the request would become permanently stuck.

AI Disclosure: Claude Code assisted in writing the tests which I reviewed and verified.

How Has This Been Tested?

I ran the existing and new unit tests.

Summary by CodeRabbit

  • Bug Fixes
    • Requests with an explicitly selected server that is missing or unavailable are marked Completed if the requested media is already available. Otherwise, they are marked Failed, with a failure notification sent when applicable. For TV requests, availability is checked across all requested seasons.
    • Requests without an explicitly selected server remain Approved when no default server is configured or available; they are not marked Failed or sent a failure notification.
    • Availability notifications are suppressed when a request is completed because the media is already available.

Walkthrough

When a Radarr or Sonarr server ID cannot be resolved, the subscriber checks whether the requested media is available. It completes available requests or marks unavailable requests failed and sends a failure notification. The subscribers also coordinate availability notifications and load season statuses before media updates.

Changes: Request server resolution

Layer / File(s) Summary
Handle unresolved server IDs
server/subscriber/MediaRequestSubscriber.ts
A shared helper handles unresolved Radarr and Sonarr servers. For an explicit server ID that no longer resolves, it checks media availability and completes the request when the required media or seasons are available. Otherwise, it marks an eligible request failed and sends a failure notification. Without an explicit server ID, it leaves the request unchanged.
Coordinate completion and notifications
server/subscriber/MediaRequestSubscriber.ts, server/subscriber/MediaSubscriber.ts
The request subscriber uses handler results to suppress duplicate availability notifications. The media subscriber loads related seasons before updates and compares their prior statuses during update handling.
Test unresolved server outcomes
server/routes/request.test.ts
Fixtures support request overrides and TV requests with seasons. Tests cover unresolved server IDs, missing defaults, available media and seasons, request statuses, and notification outcomes.

Priority: Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix · Severity of issue fixed: Medium

Suggested reviewers: gauthier-th, 0xsysr3ll

Merge Risk: Moderate · previous review e8497

Requests tied to a deleted server can now fail instead of remaining approved, but affected users still cannot recover by retrying until an administrator can change the server selection. Resolve or explicitly accept that limitation before merging.

Security architecture risk: Low · up to e8497

The new fallback remains behind request approval and does not appear to expand access to media servers. It improves resolution of requests with deleted servers, but a failed TV request can retain approved season records, leaving its status lifecycle inconsistent.

Retained concerns

  • Low · reliability · inferred: A TV request failed because its selected server was deleted can retain APPROVED season requests. The new failure path changes only the parent status, and subsequent parent-status propagation has no FAILED cleanup branch. This extends an existing failure-state inconsistency to the deleted-server case and may leave dependent state active until a later availability update.
Security review details

Security Blast Radius

  • inferred — The new outcome affects an approved request and its associated media and season records, with failure notices directed to the existing admin/system channel. The inspected change does not add server credentials, configuration writes, or a new service boundary.

Trust Boundaries and Controls

  • observed — Although request creation accepts a server ID, an unapproved request cannot enter either changed server-dispatch branch. Approval remains permission-gated, so the inspected path does not establish an authorization bypass.

Resilience and Maintainability Implications

  • inferred — The new status save and failure-notification initiation precede the separate parent-status propagation step. The inspected source does not establish serialization across repeated updates or an all-or-nothing boundary between persisted outcomes and external notification.

239-248: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Fail requests when the server settings array is empty.

The empty-array branches return before failRequestForUnresolvedServer runs. If all Radarr or Sonarr servers are deleted, the request stays APPROVED and can leave its media in PROCESSING. The retry endpoint cannot recover that request because it only accepts FAILED requests.

This changes behaviour for a very specific workflow. An admin who deliberately leaves no default Radarr/Sonarr server, and gates the server picker behind REQUEST_ADVANCED so only advanced users choose a server explicitly, will now see every plain (non-advanced) request fail. Track normal user requests without sending to arr.

A non-advanced user's request never touches the server field, so entity.serverId stays null. With no default configured, radarrSettings/sonarrSettings resolves to undefined, the override branch is skipped since serverId is null, and we land in failRequestForUnresolvedServer. Before this PR that branch just logged and left the request APPROVED. Now it flips to FAILED and fires a MEDIA_FAILED notification.

While that's the intended fix for the "forgot to set a default" case, but it also catches setups where no default was ever meant to exist for that tier of user. There's also no clean way back right now: /retry needs MANAGE_REQUESTS and doesn't accept a serverId, and the serverId-edit route only works while PENDING.

We already compute hasExplicitServer here for the message wording. Could we use it to gate behavior too? Only mark FAILED when there was an explicit serverId that no longer resolves (the deleted-override case), and keep the old silent-skip for "no default, no override" so we don't regress the advanced-only-routing setup. That narrows the fix to the case in the PR title l/linked issue as well.

There's also no clean way back right now: /retry needs MANAGE_REQUESTS and doesn't accept a serverId, and the serverId-edit route only works while PENDING.

So the next PR was going to address this part where I was going to stop the 200 -> refail loop with a 409 error then make FAILED requests editable by lifting the PENDING - only guard to include FAILED so that the admin can pick a valid server then Retry work normally.

We already compute hasExplicitServer here for the message wording. Could we use it to gate behavior too? Only mark FAILED when there was an explicit serverId that no longer resolves (the deleted-override case), and keep the old silent-skip for "no default, no override" so we don't regress the advanced-only-routing setup.

I think that this would be a happy medium so that the two setups remain functional.

@fallenbagel I have incorporated your suggestion into this fix to separate the two workflows. A stacked PR with the retry fix to allow editing the request is coming soon.

Am I correct in my understanding that the empty-array branches of the guard are for this same advanced setup use-case?
