The enumeration is cancelled when the client unsubscribes. +Over `graphql-transport-ws`, a `@defer` or `@stream` field is delivered using the `pending`/`incremental`/`completed`/`hasNext` format used by graphql-js 17 and Apollo Client's `GraphQL17Alpha9Handler`. Each field is announced once, in a `pending` entry, and identified afterwards by a short id rather than its path. A deferred field is announced in the same payload as its own value, while a streamed field is announced as soon as the payload exposing its containing data is sent. A labeled `@defer(label: "...")` surfaces that label as `pending.label` for the announced field. Streamed items always arrive in list order, and a batch of items is delivered as the `items` of one `incremental` entry addressed by that id. A payload that carries only GraphQL errors now omits the top-level `data` property instead of sending `data: null`, matching the existing request-error contract used elsewhere in the transport. + Streamed items can be grouped into batches. The `preferredBatchSize` argument of `@stream`, available with `SchemaConfig.DefaultWithBufferedStream`, has priority. Otherwise the `batching` parameter of the field applies. It is either a fixed size or a function that reads the size from the source, such as the page size of a paged SDK sequence. The function is evaluated lazily: only for a `@stream` query that does not itself specify `preferredBatchSize`, so it never runs for an ordinary or `@defer` query. ```fsharp diff --git a/src/FSharp.Data.GraphQL.Server.AspNetCore/FSharp.Data.GraphQL.Server.AspNetCore.fsproj b/src/FSharp.Data.GraphQL.Server.AspNetCore/FSharp.Data.GraphQL.Server.AspNetCore.fsproj index f37670d4b..7007f3642 100644 --- a/src/FSharp.Data.GraphQL.Server.AspNetCore/FSharp.Data.GraphQL.Server.AspNetCore.fsproj +++ b/src/FSharp.Data.GraphQL.Server.AspNetCore/FSharp.Data.GraphQL.Server.AspNetCore.fsproj @@ -20,6 +20,7 @@ + diff --git a/src/FSharp.Data.GraphQL.Server.AspNetCore/GraphQLRequestHandler.fs b/src/FSharp.Data.GraphQL.Server.AspNetCore/GraphQLRequestHandler.fs index 471f6afc7..831d8cd07 100644 --- a/src/FSharp.Data.GraphQL.Server.AspNetCore/GraphQLRequestHandler.fs +++ b/src/FSharp.Data.GraphQL.Server.AspNetCore/GraphQLRequestHandler.fs @@ -64,24 +64,24 @@ and [] GraphQLRequestHandler<'Root> if logger.IsEnabled LogLevel.Debug then deferred |> Observable.add (function + | DeferredPending (path, label, isStream) -> + let fieldKind = if isStream then "streamed" else "deferred" + logger.LogDebug ("Announced GraphQL deferred field at path: {path}", path |> Seq.map string |> Seq.toArray |> Path.Join) + match label with + | ValueSome label -> logger.LogDebug ("Deferred field label: {label}; kind: {kind}", label, fieldKind) + | ValueNone -> logger.LogDebug ("Deferred field kind: {kind}", fieldKind) | DeferredResult (data, path) -> logger.LogDebug ("Produced GraphQL deferred result for path: {path}", path |> Seq.map string |> Seq.toArray |> Path.Join) if logger.IsEnabled LogLevel.Trace then logger.LogTrace ("GraphQL deferred data:\n{data}", serializeIndented data) - | DeferredErrors (ValueNone, errors, path) -> + | DeferredErrors (data, errors, path) -> logger.LogDebug ("Produced GraphQL deferred errors for path: {path}", path |> Seq.map string |> Seq.toArray |> Path.Join) if logger.IsEnabled LogLevel.Trace then - logger.LogTrace ("GraphQL deferred errors:\n{errors}", errors) - | DeferredErrors (ValueSome data, errors, path) -> - logger.LogDebug ( - "Produced GraphQL deferred result with errors for path: {path}", - path |> Seq.map string |> Seq.toArray |> Path.Join - ) - - if logger.IsEnabled LogLevel.Trace then - logger.LogTrace ("GraphQL deferred errors:\n{errors}\nGraphQL deferred data:\n{data}", errors, serializeIndented data)) + logger.LogTrace ("GraphQL deferred errors:\n{errors}\nGraphQL deferred data:\n{data}", errors, serializeIndented data) + | DeferredCompleted path -> + logger.LogDebug ("Completed GraphQL deferred field at path: {path}", path |> Seq.map string |> Seq.toArray |> Path.Join)) GQLResponse.Direct (documentId, data, errs) diff --git a/src/FSharp.Data.GraphQL.Server.AspNetCore/GraphQLWebsocketMiddleware.fs b/src/FSharp.Data.GraphQL.Server.AspNetCore/GraphQLWebsocketMiddleware.fs index b4fcd6cc3..adcc9af4f 100644 --- a/src/FSharp.Data.GraphQL.Server.AspNetCore/GraphQLWebsocketMiddleware.fs +++ b/src/FSharp.Data.GraphQL.Server.AspNetCore/GraphQLWebsocketMiddleware.fs @@ -364,57 +364,202 @@ type GraphQLWebSocketMiddleware<'Root> SubscriptionExecutionResult.Create (output, errors) |> sendOutput id - // Incremental payloads are sent as soon as they are produced, with their path inside the initial result, - // so a client can merge them.

+0200 Subject: [PATCH 05/19] Restore original formatting in defer-related files These three files were reformatted wholesale by Fantomas even though their dev versions were not Fantomas-formatted, which buried the real change. Restore formatting to match dev so the diff shows only the @defer label argument and the deferred-test updates.

Every producer writes into a `System.Threading.Channels` channel, so no lock, no `SemaphoreSlim` gate, no `.Wait()` and no start-up barrier remain; the connection-init timeout is a `Task.WhenAny` instead of a cancelled receive, and shutdown closes the socket gracefully. The former closure nest of the middleware is split into WebSocketErrors, WebSocketMessaging, WebSocketTransport, SubscriptionPayloads, SubscriptionWorker and WebSocketConnection; `GraphQLSubscriptionsManagement` and the public `SubscriptionsDict`, `SubscriptionUnsubscriber` and `OnUnsubscribeAction` aliases are removed, as is the now unused `Observable.withCompletionMarker`. Wire contract: `SubscriptionExecutionResult.Data` and `IncrementalResult.Data` are `Skippable`, `IncrementalResult` gains `SubPath`, a deferred field is announced at the object containing it and delivered as an object map of that field, and a field whose announcement never reached the client is no longer completed.

Each field is announced once, in a `pending` entry, and identified afterwards by a short id rather than its path. A deferred field is announced at the path of the object containing it, in the same payload as its own value, and that value is delivered as an object map of the one field, which the client merges into the announced object; a streamed field is announced at its own path as soon as the payload exposing its containing data is sent, and its items are delivered as the `items` of `incremental` entries, always in list order, a batch of items in one entry. The `label` of `@defer` or `@stream` surfaces as `pending.label`. Both directives take `if: Boolean = true`, which executes the field inline when false, and `@stream` takes `initialCount: Int = 0`, the number of items delivered with the initial payload before the rest is streamed. A payload that carries only GraphQL errors omits the top-level `data` property instead of sending `data: null`, matching the existing request-error contract used elsewhere in the transport. Streamed items can be grouped into batches. The `preferredBatchSize` argument of `@stream`, available with `SchemaConfig.DefaultWithBufferedStream`, has priority. Otherwise the `batching` parameter of the field applies. It is either a fixed size or a function that reads the size from the source, such as the page size of a paged SDK sequence. The function is evaluated lazily: only for a `@stream` query that does not itself specify `preferredBatchSize`, so it never runs for an ordinary or `@defer` query.
