Goal

Parse the channel and user push preferences with the generated models, retiring DownstreamPushPreferenceDto.

Part of AND-1291

Implementation

  • Point ChannelResponse.push_preferences at the generated ChannelPushPreferencesResponse and
    DownstreamUserDto.push_preferences at PushPreferencesResponse. Both already had mappers from the
    upsert endpoint, so the hand-written DTO and its mapper are deleted.
  • Delete UpstreamLocationDto and Location.toDto(), which had no callers. The remaining
    DownstreamLocationDto moves to a file of the same name.
  • Move the regression test that pins every chat preference toggle onto PushPreferencesResponse.
  • Send the members of createChannel(channelType, channelId, CreateChannelParams) as the generated
    ChannelMemberRequest, which addMembers already uses, and delete UpstreamMemberDataDto and its
    adapter. The wire format is unchanged.
  • Rename UpstreamReactionDtoAdapter to ReactionRequestAdapter, after the model it serializes.

Testing

Mutation sweep over both push preference mappers: zero survivors. Added a serialization test pinning the
createChannel members JSON.

Device-probed both paths with per-category chat preferences, a snooze and a level change, comparing every
field against the upsert response each time:

  • channel: queryChannels after each step
  • user: me from connection.ok after a relaunch

All fields matched, including every toggle.

Device-probed createChannel with one member carrying extra data and one without: the request body kept
the flattened shape, and a re-query returned both members with the extra data only on the first.

Summary by CodeRabbit

  • Bug Fixes
    • Fixed channel creation so member details, including custom fields such as nicknames, are correctly included in the request.
    • Updated push preference handling to use the appropriate response format for user and channel data, preserving chat-level settings and preference options. This helps ensure push preference information is interpreted consistently across responses.

Walkthrough

Channel creation now converts members to channel-member request objects. User and channel response models use network push-preference response types. The changes also remove obsolete DTO mappings and adapters, rename the reaction adapter, and update related tests and fixtures.

Changes

API model and serialization updates

Layer / File(s) Summary
Channel-member request serialization
stream-chat-android-client/src/main/java/io/getstream/chat/android/client/ChatClient.kt, stream-chat-android-client/src/main/java/io/getstream/chat/android/client/api2/mapping/DtoMapping.kt, stream-chat-android-client/src/main/java/io/getstream/chat/android/client/api2/model/dto/UpstreamMemberDataDto.kt, stream-chat-android-client/src/main/java/io/getstream/chat/android/client/parser2/..., stream-chat-android-client/src/test/java/io/getstream/chat/android/client/parser2/CreateChannelMembersSerializationTest.kt, stream-chat-android-client/src/test/java/io/getstream/chat/android/client/api2/mapping/DtoMappingTest.kt
createChannel converts members to channel-member request objects. The old member DTO and adapter are removed. A serialization test checks that member fields, including extra data, appear at the member object’s root.
Push-preference response types
stream-chat-android-client/src/main/java/io/getstream/chat/android/client/api2/mapping/DomainMapping.kt, stream-chat-android-client/src/main/java/io/getstream/chat/android/client/api2/model/dto/..., stream-chat-android-client/src/main/java/io/getstream/chat/android/client/api2/model/response/ChannelResponse.kt, stream-chat-android-client/src/test/java/io/getstream/chat/android/client/Mother.kt, stream-chat-android-client/src/test/java/io/getstream/chat/android/client/api2/mapping/DomainMappingTest.kt, stream-chat-android-client/src/test/java/io/getstream/chat/android/client/parser2/testdata/UserDtoTestData.kt
DownstreamUserDto and ChannelResponse use their respective network response types for push preferences. The removed downstream DTO mapping is no longer tested; fixtures and mapping tests use PushPreferencesResponse.
Remaining DTO mappings and reaction adapter
stream-chat-android-client/src/main/java/io/getstream/chat/android/client/api2/mapping/DtoMapping.kt, stream-chat-android-client/src/main/java/io/getstream/chat/android/client/api2/model/dto/DownstreamLocationDto.kt, stream-chat-android-client/src/main/java/io/getstream/chat/android/client/parser2/..., stream-chat-android-client/src/test/java/io/getstream/chat/android/client/parser2/ReactionRequestAdapterTest.kt
The upstream location DTO and mappings to it are removed. The reaction adapter is renamed to ReactionRequestAdapter, and the parser registration and test name use the new name.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~12 minutes

Change: Refactor

Suggested reviewers: velikovpetar

Merge Risk: 🔵 Low · up to 47639

The member request format is not asserted through channel creation. The change is mergeable with a caller-level test as follow-up.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 47639

The inspected request and response paths preserve the key member fields and chat preference values, with no demonstrated new authorization bypass. Server-side validation and concurrent request behavior remain less certain.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The directly inspected request-side scope is channel creation with supplied member identities and custom data. The response-side scope is the client’s user and channel push-preference state; server-side tenant reach and authorization outcomes are not established by these client paths.

Trust Boundaries and Controls

  • observed — The client builds the member request before invoking its existing create-channel precondition and sends service responses through internal preference mappings. These source paths do not establish what authorization or reserved-key validation the service applies.

Hardening Proposals

  • proposed — Consider an explicit reserved-key policy for flattened member custom data, or validate identity and role fields at the service boundary. Root-level key collisions are a pre-existing serialization characteristic, not a demonstrated regression from this PR.

1-71: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick win

Add a caller-level assertion for the serialized member payload.

CreateChannelMembersSerializationTest maps MemberData and serializes a manually constructed QueryChannelRequest. It does not execute ChatClient.createChannel, where the changed conversion and request assembly occur.

The existing caller tests invoke createChannel, but they only assert plugin callbacks and the returned result. They do not inspect the request passed to api.queryChannel. A regression in the caller can therefore pass these tests.

Add a caller-level test or capture the API request and assert that member extra data is flattened in the assembled request.
