feat(tracing): Implement strict trace continuation#5829
Merged
Conversation
Expose strictTraceContinuation and orgId options for cross-org trace validation. The JS layer is handled by @sentry/core 10.43.0 which already implements shouldContinueTrace and org_id propagation in DSC. This commit adds native bridge support to pass these options through to the Android (SentryAndroidOptions) and iOS (SentryOptions) native SDKs during initialization, and adds comprehensive tests covering: - Option pass-through to native SDK initialization - Option pass-through via Sentry.init() - continueTrace behavior with matching/mismatching org IDs - strictTraceContinuation=true/false decision matrix Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

📜 Description
Add support for
strictTraceContinuationandorgIdoptions in the React Native SDK.JS layer: No source changes needed —
@sentry/corealready implements the full feature (option types,shouldContinueTrace(), org_id in DSC,continueTraceintegration). SinceReactNativeOptionsextends@sentry/core'sOptions, both options are automatically available.Native bridge: Pass
strictTraceContinuationandorgIdthrough to native iOS/Android SDKs during initialization.Changes:
RNSentryStart.java— PassstrictTraceContinuation(boolean) andorgId(string/number) toSentryAndroidOptionsRNSentryStart.m— PassstrictTraceContinuation(BOOL) andorgId(NSString) toSentryOptionsstrictTraceContinuation.test.ts(new) — 10 tests covering the full decision matrix via@sentry/core'scontinueTracesdk.test.ts— 4 tests verifying options flow throughSentry.init()wrapper.test.ts— 2 tests verifying options pass through the native bridge💡 Motivation and Context
Implements Strict Trace Continuation spec. Prevents cross-org trace continuation by validating org IDs in distributed traces.
Part of the Strict Trace Continuation initiative.
Native SDK dependencies now merged and bumped on main:
💚 How did you test it?
