Goal

Migrate the file upload response and the message translation request body to the generated network models.

Part of AND-1291

Implementation

  • Add generated FileUploadResponse; remove the hand-written UploadFileResponse and rename its mapper and
    test to match. It covers all four upload endpoints (/channels/{type}/{id}/file,
    /channels/{type}/{id}/image, /uploads/file, /uploads/image).
  • The generated file is nullable, matching the wire: Go tags it omitempty, so an empty asset URL is
    omitted and the old non-null file: String would have failed to parse. A response without a URL has
    nothing to attach, so toUploadedFile() now returns a Result and reports it as a failure;
    StreamFileUploader uses flatMap to carry that through.
  • Add generated TranslateMessageRequest; remove the hand-written one. ChatClient.translate still takes
    a String, converted with Language.fromString, which falls back to Unknown and sends the value
    through unchanged, so an unsupported language is still rejected by the server rather than locally.
  • Exclude the generated network/** path from the LongMethod detekt rule: the models map each wire enum
    in one exhaustive when (57 entries for Language), which a formatter cannot split and which would be
    regenerated anyway.

Testing

  • UploadFileResponseMappingTest covers the mapping, a missing thumbnail, and the missing-URL failure.
  • TranslateMessageRequestAdapterTest asserts the serialized body for a known language, for one the models
    do not know, and for every one of the 57 languages the endpoint accepts. Removing the Language adapter
    registration makes them fail.
  • Device-probed all four upload endpoints plus translate. Every upload resolved a CDN URL, and all four
    returned no thumb_url, so the nullable thumbnail path is the normal shape rather than an edge case.
    translate sent {"language":"fr"}, unchanged from the hand-written body, and an invalid language was
    rejected by the server with its list of accepted values. That list matches the generated enum exactly,
    all 57 values.

Summary by CodeRabbit

  • Bug Fixes

    • Improved file and image upload handling, including support for optional thumbnails and missing file URLs.
    • Added upload duration information to processed upload responses.
    • Improved message translation requests for supported and unrecognized language codes.
  • Tests

    • Added coverage for upload response parsing, upload failures, translation language handling, and serialization behavior.

Review Change Stack

Walkthrough

The PR moves upload and translation models into the network models package. It updates API return types, response mapping, language serialization, uploader handling, fixtures, tests, and Detekt configuration.

Changes

Network model migration

Layer / File(s) Summary
Upload response model and conversion flow
config/detekt/detekt.yml, stream-chat-android-client/src/main/java/io/getstream/chat/android/network/models/FileUploadResponse.kt, stream-chat-android-client/src/main/java/io/getstream/chat/android/client/api/RetrofitCdnApi.kt, stream-chat-android-client/src/main/java/io/getstream/chat/android/client/api2/mapping/*, stream-chat-android-client/src/main/java/io/getstream/chat/android/client/uploader/StreamFileUploader.kt, stream-chat-android-client/src/test/...
FileUploadResponse replaces UploadFileResponse. The response adds duration, nullable file, and thumbUrl. Upload conversion now returns success or failure through flatMap. Fixtures and uploader tests use the new model.
Translation request model and serialization
stream-chat-android-client/src/main/java/io/getstream/chat/android/network/models/TranslateMessageRequest.kt, stream-chat-android-client/src/main/java/io/getstream/chat/android/client/parser2/MoshiChatParser.kt, stream-chat-android-client/src/main/java/io/getstream/chat/android/client/api2/..., stream-chat-android-client/src/test/java/io/getstream/chat/android/client/api2/..., stream-chat-android-client/src/test/java/io/getstream/chat/android/client/parser2/...
TranslateMessageRequest now defines supported languages, preserves unknown codes, and provides a Moshi adapter. The API constructs languages with fromString, and parser and API tests use the network model.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: ⚪ Minimal · up to 0d4f3

The PR moves upload and translation payloads to generated models while preserving existing wire behavior, so user-facing impact should be unchanged. Merge-readiness risk is minimal, with only minor follow-up needed for lint coverage and undocumented suppressions.

Poem

A rabbit hops through models bright,
Uploads gain new fields tonight.
Languages parse, then travel true,
Moshi knows what they should do.
Tests bloom softly, neat and round.

containing the network glob from the entire network directory to only the
network/models directory, while preserving exclusions for generated model code
and enabling checks for network/infrastructure files.

In
`@stream-chat-android-client/src/main/java/io/getstream/chat/android/network/models/FileUploadResponse.kt`:
- Around line 17-22: Update the file-level `@file`:Suppress declaration in
FileUploadResponse to remove the unused ArrayInDataClass, EnumEntryName, and
UnusedImport suppressions; retain RemoveRedundantQualifierName only if the
generated-model template requires it, otherwise remove that suppression as well.

In
`@stream-chat-android-client/src/main/java/io/getstream/chat/android/network/models/TranslateMessageRequest.kt`:
- Around line 17-22: Review the file-level Suppress annotation in
TranslateMessageRequest and remove every diagnostic suppression that is not
required. If code generation requires any remaining suppression, retain only
that entry and document the specific generator constraint; otherwise remove the
annotation entirely.
