Goal

Unknown events, such as an app's custom events, were the last user of DownstreamUserDto. Their user is now read like every other event user, so the DTO can go.

Part of AND-1291

Implementation

  • UnknownEventDto.user is the generated UserResponseCommonFields and maps through the same toDomain() as other event users. Own-user fields (unread counts, invisible, privacy_settings) on that user now land in extraData, as they do on other events.
  • DownstreamUserDto, its adapter, DeviceDto.toDomain() and their tests and test data are deleted.

Testing

UnknownEventParsingTest parses custom events with a user, with own-user fields, with an invalid user and without one.

Summary by CodeRabbit

  • Bug Fixes
    • Improved handling of users included with unrecognized events: available user details and custom fields are preserved, and events without a user remain usable.
    • Added coverage for custom event payloads and user data, including cases where user information is incomplete.

📝 Walkthrough

The changes remove the downstream-user DTO, its mapping and parser support, and related test fixtures. Unknown-event users now use UserResponseCommonFields. New tests cover mapped user fields, custom data, absent users, and ID-only users.

Estimated code review effort

Priority: ⬇️ Low

Merge Risk: ⚪ Minimal · up to e8b4b

No runtime regression is established. The remaining follow-up is to test that unknown events preserve invisible and privacy_settings in extraData; this does not block merging.

I’m a rabbit with a DTO gone,
I parse event users as fields,
Custom data stays tucked away,
Tests check what each event yields,
I twitch my nose and hop along.

50-56: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick win

Add invisible and privacy_settings to the unknown-event fixture.

The test currently checks only unread counts. It passes if invisible or privacy_settings is dropped from User.extraData. Add both fields to this same UnknownEvent caller-path test.

Suggested fix
-        val user = parse(customEvent(USER.replace("}", ""","total_unread_count":4,"unread_channels":2}"""))).user!!
+        val user = parse(customEvent(USER.replace("}", ""","invisible":true,"privacy_settings":{"typing_indicators":{"enabled":false}},"total_unread_count":4,"unread_channels":2}"""))).user!!

         user.totalUnreadCount shouldBeEqualTo 0
-        user.extraData shouldBeEqualTo mapOf("nickname" to "Chewie", "total_unread_count" to 4.0, "unread_channels" to 2.0)
+        user.extraData shouldBeEqualTo mapOf(
+            "nickname" to "Chewie",
+            "invisible" to true,
+            "privacy_settings" to mapOf("typing_indicators" to mapOf("enabled" to false)),
+            "total_unread_count" to 4.0,
+            "unread_channels" to 2.0,
+        )
