Goal
Records thread information for unhandled JS errors. The thread information was not captured for unhandled JS errors when
BSGThreadSendPolicyUnhandledOnlywas set because the native layer used the presence ofBSG_KSCrashTypeUserReportedas thecrashTypeto determine whether an error was unhandled instead.This change alters the
captureThreadTracemethod to calculate whether threads should be captured or not, and setsthreadTracingEnabledappropriately. By default this value is set when installing KSCrash - for handled errors this value is overwritten.Additionally the crash context has been set to a local struct, which avoids the scenario where multiple notify calls overwrite a global struct.
Note: sending a handled error will overwrite the crash context currently which means the thread send behaviour is incorrect for unhandled errors sent after handled errors. This will be addressed in a separate PR which avoids reusing the crash context.
Tests
Covered by existing E2E test coverage, additionally verified in an Objective C example app against handled + unhandled errors.
