From 3704e51dff0d857fffe8d1ed9fad917d53369358 Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 20 Apr 2026 02:37:27 +0000 Subject: [PATCH 1/5] [ADR-179] ApplicationLifecycle recycle loop and BlazorAppScope.RecycleAsync MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the scope recycle loop in ApplicationLifecycle.ExecuteAsync: - IApplicationRecycleSignal / ApplicationRecycleSignal: new cross-service interface backed by a CancellationTokenSource; RequestRecycle() cancels it, Token is linked into the scope work item, Reset() creates a fresh CTS - ExecuteAsync refactored to a while loop; linked token from stoppingToken + signal.Token passed into InvokeInScopeAsync each iteration - Steady-state path: signal fires during Task.Delay(Infinite) → OCE → cleanup → log RecyclingScope → RecycleScopeAsync() → signal.Reset() → loop - Init-phase path: signal fires during InitializeAllAsync → cancel → cleanup → signal.Reset() → loop without RecycleScopeAsync (scope TCS still valid) - IPreScopeInitializer services awaited only before the first scope (before the while loop), not re-awaited on recycles - BlazorAppScope.RecycleAsync: now calls IJSRuntime.InvokeVoidAsync("location.reload") - Registered IApplicationRecycleSignal as singleton in DI - Added EventId 712 ApplicationLifecycle_RecyclingScope log message - Added 5 unit tests covering both recycle paths, loop continuation, pre-initializer not re-awaited, and signal.Reset() called after recycle - Updated _doc_Lifecycle.md: removed "Future Plans" stub, documented the implemented recycle loop, signal, and two recycle paths https://claude.ai/code/session_01VENkux7qyWvUsKWEzgNC3s --- .../Components/BlazorAppScope.cs | 11 +- .../Configuration/HostBuilderExtensions.cs | 3 +- .../Logging/MessageLogger.cs | 3 + .../Lifecycle/ApplicationLifecycle.cs | 116 ++++++--- .../Lifecycle/ApplicationRecycleSignal.cs | 16 ++ .../Lifecycle/IApplicationRecycleSignal.cs | 14 ++ .../Services/Lifecycle/_doc_Lifecycle.md | 50 +++- .../Lifecycle/ApplicationLifecycleTests.cs | 229 +++++++++++++++++- 8 files changed, 389 insertions(+), 53 deletions(-) create mode 100644 src/AdaptiveRemote.App/Services/Lifecycle/ApplicationRecycleSignal.cs create mode 100644 src/AdaptiveRemote.App/Services/Lifecycle/IApplicationRecycleSignal.cs diff --git a/src/AdaptiveRemote.App/Components/BlazorAppScope.cs b/src/AdaptiveRemote.App/Components/BlazorAppScope.cs index 358c1815..ba134a44 100644 --- a/src/AdaptiveRemote.App/Components/BlazorAppScope.cs +++ b/src/AdaptiveRemote.App/Components/BlazorAppScope.cs @@ -1,5 +1,7 @@ -using AdaptiveRemote.Services.Lifecycle;
