Description

TMDB sometimes splits one real show into two catalog entries (a different network or era gets its own listing) while TheTVDB keeps it as a single series. For example, The Great British Bake Off, its Channel 4 years are a separate TMDB entry from the rest, and both correctly point to the same TVDB series.

That split is what breaks "Request More" on an already-tracked show. A show can end up tracked with no TVDB ID with no request ever involved, matched into Seerr by TMDB ID alone when it was already in the media server. Request more of it, and the match modal appears correctly, since TMDB has no ID for it. The user picks the right match and submits. Seerr can't persist that pick, though: the other TMDB entry for the same real show already claims that TVDB ID on its own row. The pick is silently dropped, this row's TVDB ID stays null, and the request reaches Sonarr dispatch with nothing to identify the series. Seerr then removed the records for the show and the request and returned an error, so an already-tracked show with real history disappeared over a collision the user had no way to see.

This PR now works out the ID at dispatch time instead, from TheTVDB directly, then Sonarr as a fallback, and leaves a failed request visible with a notification rather than deleting it, regardless of how that state was reached. Where a show's seasons are numbered differently on TheTVDB than on TMDB, the request fails rather than being sent, so nothing is grabbed under the wrong season number. Requesting the 2024 series of The Great British Bake Off still fails for that reason and is expected to, since reconciling the two numbering schemes is separate work. Where a show's seasons are numbered differently on TheTVDB than on TMDB, the request fails rather than being sent, so nothing is grabbed under the wrong season number. Requesting the 2017 series of The Great British Bake Off still fails for that reason and is expected to, since reconciling the two numbering schemes is separate work. The same failure path also covers TheTVDB being unreachable or returning an incomplete response: the season numbering can't be confirmed, so the request fails rather than dispatching a number nobody has checked.

How Has This Been Tested?

  • via unit tests and manually requesting the Greate British Bake Off 2017 and watching it fail as intended (pr 3 will show why and pr 4 will give a solution)

📝 Walkthrough

Walkthrough

The change adds TVDB season lookup and Sonarr TMDB lookup methods. Media requests now backfill non-conflicting TVDB IDs, validate requested seasons, and preserve failed requests with notifications. Tests cover lookup, persistence, fallback, conflicts, failures, and season matching.

TVDB conflict-safe persistence

Sonarr processing resolves missing TVDB IDs, validates requested seasons, and marks unresolved or mismatched requests as failed with notifications. Tests cover fallback paths, conflicts, lookup failures, empty official-season results, specials, and season matching.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 968d0

The change improves TVDB resolution and preserves failed requests, but legitimate unaired-season requests may be rejected and concurrent scans can still fail on duplicate TVDB IDs. These issues should be addressed before merge.

675-687: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Exclude specials from the season match check.

Tvdb.getOfficialSeasons returns only seasons with number > 0. This filter maps every requested season number, including season 0 when settings.main.enableSpecialEpisodes is enabled. For season 0, tvdbSeasons.find(...) returns undefined, so seasonsMatch returns false and season 0 always lands in unmatchedSeasons.

Result: a request that includes specials is marked FAILED whenever TMDB has no TVDB ID and tvdbSeasons is non-empty. A mixed request such as [0, 1] fails even when season 1 matches.

Restrict the check to positive season numbers.

             .map((season) => season.seasonNumber)

Comment thread server/subscriber/MediaRequestSubscriber.ts
A failed season lookup returned an empty list, which the season guard reads as a show with no
official seasons and skips. Any transport error or incomplete record therefore dispatched to Sonarr
unverified. Now it returns a null for both cases so they stay distinguishable from a confirmed empty
list, and fail the request with a notification when the seasons cannot be checked
Two TMDB entries can map to one TVDB series, but only one media row may hold that ID. Creating a row
with an ID another row already owns threw a unique constraint error, failing the request outright
and, in the scanner, the whole library. This skips the ID when it is already taken and keeps the
row, since the TMDB ID is what identifies it and dispatch resolves the TVDB ID per request anyways.

Make scanner TVDB ID assignment atomic.

Two different TMDB entries can run concurrently and use the same TVDB ID. They use different tmdbId lock keys, so both can pass this lookup before either save occurs. The later save then violates the unique Media.tvdbId constraint and rejects the scanner bundle.

Handle a unique-conflict error during newMedia save by clearing tvdbId and retrying, or make the ownership check and insert atomic. Add a concurrent duplicate-ID scanner test.
