From 12d85365881ed3e82387a665533f11edf3f35354 Mon Sep 17 00:00:00 2001 From: Matthew Date: Tue, 9 Dec 2025 02:37:27 -0800 Subject: [PATCH] feat(ios): enhance recovery logging and metrics recording Implement comprehensive logging and observability for recovery operations: - Add HistoryDAO for Core Data history recording - recordRecovery() method with execution time tracking - recordRecoveryFailure() method with detailed error info - Query helpers for history retrieval - Enhance DailyNotificationReactivationManager logging: - Add execution time tracking (startTime/endTime) - Enhanced error logging with NSError details (domain, code, userInfo) - Comprehensive logging at each recovery step - Missed/future notification count logging - Implement Core Data persistence for recovery metrics: - Recovery execution time - Missed notification count - Rescheduled notification count - Verified notification count - Error count - Diagnostic JSON with full recovery context - Update recovery methods to record history: - Cold start recovery - Termination recovery - Boot recovery - All with timing and metrics Completes section 7.1 (Recovery Logging) and 7.2 (Metrics Recording) of iOS implementation checklist. --- docs/IOS_IMPLEMENTATION_CHECKLIST.md | 30 +- ...DailyNotificationReactivationManager.swift | 156 +++++++-- ios/Plugin/HistoryDAO.swift | 300 ++++++++++++++++++ 3 files changed, 442 insertions(+), 44 deletions(-) create mode 100644 ios/Plugin/HistoryDAO.swift diff --git a/docs/IOS_IMPLEMENTATION_CHECKLIST.md b/docs/IOS_IMPLEMENTATION_CHECKLIST.md index c1331be..511c3b4 100644 --- a/docs/IOS_IMPLEMENTATION_CHECKLIST.md +++ b/docs/IOS_IMPLEMENTATION_CHECKLIST.md @@ -356,24 +356,24 @@ Complete checklist of iOS code that needs to be implemented for feature parity w ### 7.1 Recovery Logging -- [ ] Add comprehensive logging: -
