Expose upload context with message id to FileUploader (develop) - #6669
Conversation
Port of the v6 change to develop. Add FileUploadContext, a read-only, SDK-constructed context handed to new FileUploader.sendFile/sendImage overloads. For message attachments it carries the id the message will be sent with, known before the message reaches the Stream API. The new overloads delegate to the existing ones by default and are compiled as JVM default methods, so current FileUploader implementations, Kotlin or Java, keep working unchanged.

Goal
Port of #6668 to develop: expose the id of the message an attachment belongs to to custom
FileUploaderimplementations, so apps uploading to their own CDN can associate the uploaded file with the message before it reaches the Stream API.Part of AND-1453
Implementation
FileUploadContext, a read-only, SDK-constructed context (channel type/id, user id, message id). Its constructor is internal so new properties can be added later without breaking implementers.FileUploader.sendFile/sendImageoverloads receiving the context. They delegate to the existing overloads by default and compile as JVM default methods, so currentFileUploaderimplementations, Kotlin or Java, keep working unchanged. The API diff is purely additive.UploadAttachmentsWorkerthroughAttachmentUploaderand internalChatClient/ChatApioverloads down toMoshiChatApi, which builds the context and calls the new overloads. Direct (non-message) uploads pass a null message id.Differences from the v6 version are mechanical: the state-module tests live under
stream-chat-android-clienthere, and the worker's parallel upload path is preserved.Testing
MoshiChatApiTest(context contents, null message id for plain uploads),AttachmentUploaderTests(file and image forwarding),ChatClientChannelFileUploaderTests(overload forwarding),FileUploaderTest(default delegation contract),FileUploadContextTest, and the worker-to-uploader assertion inUploadAttachmentsIntegrationTests.Summary by CodeRabbit
