Fix concurrent ffmpeg segment racing

2026-08-04T16:33:42Z

This is a nasty one. The failure mode is: 1. Request A started FFmpeg and waited for a segment. 2. Request B requested an earlier or far away segment. 3. Jellyfin thought FFmpeg should to restart at a different position. 4. Request B killed the existing transcoding job. 5. Killing that job cancelled the same token request A was using. 6. The cancellation produced http 500 to request A. To fix this: we lock transcoding job state changes and segment handling per playlist, and use a thread safe counter to track how many http responses are still using each job’s segments. A job is only stopped or replaced once that counter reaches zero.

Make ItemUpdateController.UpdateItem internal instead of reflection

2026-07-21T06:51:30Z

Addresses review feedback from @Bond-009 on PR #17370: the test helper InvokeUpdateItem was invoking the private UpdateItem(BaseItemDto, BaseItem) method via reflection. Jellyfin.Api.csproj already grants InternalsVisibleTo("Jellyfin.Api.Tests"), so the method is changed to internal and the test now calls it directly, removing the GetMethod/Invoke boilerplate.

fix: don't throw ArgumentNullException on partial UpdateItem payloads (#17366)

2026-07-17T15:20:30Z

BaseItemDto.Genres, .Tags, and .ProviderIds are plain auto-properties with no default initializer, so they deserialize to null when a client omits them from a partial POST /Items/{itemId} body. The OpenAPI spec documents every BaseItemDto field as optional, but ItemUpdateController.UpdateItem fed these three properties straight into Distinct()/Select()/ToList() without a null check, so a request that (for example) only sets Tags throws ArgumentNullException("source") once it reaches the unguarded Genres line, before Tags is even processed. Guard all three assignments with the same "if (request.X is not null)" pattern already used for the neighboring Studios/Taglines/ProductionLocations fields in this method, so omitted fields are left unchanged instead of crashing the request. Adds ItemUpdateControllerTests covering the reported repro (only Tags supplied) and a companion case asserting existing Genres/ProviderIds are preserved when omitted from the payload.
