Description of the pull request

When logging in as guest user the backend generates a userId for you. That's in the token, but not available when constructing the tokenManager. By getting it from the token directly we are always sure to have the right user id.

Neede for: GetStream/stream-feeds-flutter#113

Summary by CodeRabbit

  • Breaking Changes

    • Authentication can now resolve the active token manager and user identity dynamically through a provider. Existing fixed-manager integrations remain supported.
  • Bug Fixes

    • Kept request user IDs aligned with the active authentication token.
    • Prevented automatic WebSocket retries after token-expired server errors while preserving retries for other retryable errors.
  • Tests

    • Added coverage for token-manager replacement, user identity handling, token expiration, and WebSocket reconnection behavior.

Review Change Stack

Warning

Review limit reached

@renefloor, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 78 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

AuthInterceptor now supports fixed and runtime-resolved token managers. Request identity and token-expiration handling use the active manager. Tests cover manager replacement, expiration behavior, and WebSocket reconnection states.

Changes

Dynamic authentication runtime

Layer / File(s) Summary
Dynamic token manager contract
packages/stream_core/lib/src/api/interceptors/auth_interceptor.dart, packages/stream_core/CHANGELOG.md
AuthInterceptor adds TokenManagerProvider support, preserves fixed-manager construction, resolves the active manager during request processing, and documents the constructor change.
Authentication request and expiration validation
packages/stream_core/test/api/interceptors/auth_interceptor_test.dart
Tests capture requests, generate JWT-like tokens, verify manager replacement and identity propagation, and confirm static-provider expiration errors do not trigger refresh or retry.
WebSocket reconnection state validation
packages/stream_core/test/ws/client/web_socket_connection_state_test.dart
Tests verify that token-expired disconnects disable reconnection and generic retryable server errors preserve reconnection.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 718e2

The PR updates guest authentication to use the user ID from the token, with no actionable merge-blocking risk remaining beyond normal checks and review.

// Use the resolved token's own user id rather than
// `_tokenManager.userId`: some token providers (e.g. guest exchanges)
// can resolve to a different id than the one originally requested, and

In my opinion the token should always match the id set in the token manager. if its different we should expire the current token and get a new token for the user id set in the manager.

In `@packages/stream_core/lib/src/api/interceptors/auth_interceptor.dart`:
- Around line 80-84: Bind token-expiration handling to the dispatched request by
storing the resolved token manager in RequestOptions.extra immediately after
token loading. In onError, compare that stored manager with the current
_tokenManager and only expire and retry when they are identical; otherwise
forward the error, while preserving the static-provider path. Add a regression
test covering a manager swap after dispatch.
