iOS agent release notesRSS

Bug fixes

• Fixed a crash (SIGSEGV or SIGBUS in SessionAttributeManager::generateJSONObject) on the harvest thread, which could also corrupt the heap and cause crashes elsewhere. The agent copied its internal session attributes, such as memUsageMb and lastInteraction, during a harvest without holding the lock that guards them, so it could read them while another thread was updating them. This issue was present in 7.7.8 and earlier.
• Fixed the main thread blocking, and apps being terminated by the iOS watchdog (0x8BADF00D), once the event buffer was full and the app kept making network requests. The agent held a lock while it rewrote its on-disk copy of buffered events, and threads recording events, including the main thread, waited on that lock. Events dropped from a full buffer were also never removed from that copy, so it grew and was rewritten in full for every new event. Writes now happen without holding the lock, are batched, and dropped events are removed. This issue was present in 7.7.8 and earlier.
• Fixed events occasionally going unreported when they were recorded, for example by a network request finishing, at the same moment the agent collected buffered events for a harvest. The agent cleared the buffer a second time after releasing its lock, which discarded any event added in between before it was sent. This issue was present in 7.7.8 and earlier.
• Fixed the agent's own JSON work being recorded as app activity. NSJSONSerialization is instrumented for interaction traces, and the agent called it directly for every log message as well as for session attributes and handled exceptions. That added the agent's internal work to interaction traces and, when the app logged heavily, could overwhelm tracing. The agent now calls the original, uninstrumented implementation. This issue was present in 7.7.8 and earlier.
• Fixed Session Replay accessibility identifier masking rules set in Application Settings being ignored on iOS. New Relic sends these rules to iOS apps with the identifier accessibilityIdentifier, but the agent only recognized tag, so every such rule was dropped. Both values are now accepted. A malformed rule is now skipped with a warning instead of discarding every rule or crashing the agent.
• Fixed possible crashes in Session Replay masking. Masking lists could be updated by a reconnect, or by addSessionReplayMaskedAccessibilityIdentifier: and related APIs, while a frame was being captured, without holding the lock that capture uses. Custom masking rules containing values that can't be saved to NSUserDefaults, such as null, could also stop the app when the agent saved its configuration. Rules are now cleaned before they are stored, and every update to the masking lists is locked.
• Fixed WKWebView navigations being reported without a URL in apps built with the iOS 27 SDK. With that SDK, WKWebView.URL can still be nil when a navigation starts. The agent now falls back to the main-frame request URL from decidePolicyForNavigationAction.
• Fixed possible EXC_BAD_ACCESS crash when using addHTTPHeaderTrackingFor.

Bug fixes

• Fixed an issue where calling recordError under low-memory conditions could terminate the host application. Error reports are now dropped and logged, and New Relic agent frames are trimmed from the top of the recorded stack.
• Fixed a crash in NRMALoggerBridge::log caused by a missing argument in a log format string when removing session attributes. Corrected two additional invalid format strings in the same component.
• Fixed an issue where distributed tracing timestamps (tracestate and payload ti) were sent in seconds instead of milliseconds when using the new event system.
• Fixed an issue where successful MobileRequest events lost all distributed tracing attributes when a cross-platform SDK passed traceHeaders.
• Updated the native agent to prevent adding duplicate distributed traces to requests reported with traceHeaders by Flutter, React Native, or other hybrid agents. This applies to both MobileRequest and MobileRequestError in both event systems.
• Enforced minimum and maximum boundary limits for MaxEventPoolSize and MaxEventBufferTime configuration settings (maximum buffer time capped at 600 seconds).
• Updated recordCustomEvent to return a boolean indicating whether the event was successfully added when using the new event system, rather than always returning YES.
• Updated React Native JavaScript error uploads to pass the correctly cased ReactNative platform value, matching the Android agent behavior.

새로운 기능

• 문서화된 최소 플랫폼 요구 사항에 맞춰 iOS 15.0 및 tvOS 15.0의 최소 배포 버전을 타겟으로 하도록 XCFramework 빌드 설정을 업데이트했습니다.

버그 수정

• 수집 설정 읽기 중 발생하는 크래시(objc_msgSend 내의 SIGSEGV)를 해결했습니다. /connect 응답 또는 NSUserDefaults 딕셔너리에서 자동 해제 풀이 비워진 후 assign (으)로 선언된 NRMAHarvesterConfiguration의 8개 객체 속성이 댕글링 포인터를 유지했습니다.

• /connect 응답에서 at_capture 속성이 누락된 경우 세션에 대한 모든 활동 트레이스가 삭제되는 문제를 해결했습니다.

• 리액트 네이티브 오류와 함께 보고된 platform 값을 ReactNative(으)로 보고하도록 수정했습니다.

• 호스트 플랫폼 버전 대신 iOS 에이전트 버전을 정확하게 보고하도록 JavaScript 오류 페이로드의 agentVersion 필드를 수정했습니다.

• 커스텀 속성 유효성 검사 업데이트: NSArray 또는 NSDictionary 객체를 이벤트 속성으로 전달하면 이제 일반적인 "value must be an NSString, NSNumber, or BOOL" 경고 메시지를 대체하여 지원되지 않는 유형을 식별하는 명시적 오류를 로그에 기록합니다.

이 릴리스에서 수정됨

• 세션 리플레이 이벤트가 Meta/FullSnapshot보다 먼저 정렬되는 문제를 수정했습니다.

• NRMAExceptionMetaDataStore을(를) 다시 작성하여 잠재적인 데이터 누락 문제를 수정했습니다.

• RN 소스맵 업로드 스크립트를 수정했습니다.

• checkAndHandleSessionTimeout에서 잠재적인 세션 재시작 문제를 수정했습니다.

이 릴리스에서 수정됨

• nil로 setUserId를 호출할 때 항상 새 세션이 시작되는 버그를 수정했습니다.

• 이전 세션 리플레이 프레임이 새 세션과 함께 업로드되는 것을 방지했습니다.

• 도달 가능성이 매번 콜백을 호출하는 대신 변경 시 콜백을 업데이트하도록 변경했습니다.

• 16진수 무효화 충돌을 수정했습니다.

• setUserId vendorId 충돌을 수정했습니다.

• NRMA 트레이스 컬렉션 전반의 원자성을 수정했습니다.

• setUserId가 동기식으로 유지되도록 수정했습니다.

• 세션 리플레이를 Timer에서 DispatchSourceTimer로 변경하여 크래시를 수정했습니다.

• CoreData NRMAMethodProfiler 충돌을 수정했습니다.

• sessionAttributeJSONString이 딕셔너리의 스냅샷을 가져오도록 하여 충돌을 수정했습니다.

• SwiftUI 텍스트 너비 보정 오프셋을 콘텐츠에 고정하여 MSR 텍스트를 수정했습니다.

• JSErrorController 메모리 누수를 수정했습니다.

• 이진 굵기 특성 대신 정확한 숫자 글꼴 굵기를 참조하여 MSR 텍스트를 수정했습니다.

• dsym-upload-tools run-symbol-tool에 appVersion 매개변수를 추가하도록 dSYM 업로드 도구를 업데이트했습니다.

• MSR에서 누락된 SwiftUI 모달을 수정했습니다.
