From 9b7258f8c3c1920b7fe9e31cf974afe86aba8360 Mon Sep 17 00:00:00 2001 From: Jonathan Horvath Date: Wed, 12 Nov 2025 12:43:01 -0500 Subject: [PATCH 1/6] Fix communication settings reconnection race condition MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Resolves issue where closing the success dialog too quickly would prevent the device from reconnecting with new communication settings. The problem was that ReconnectAfterCommunicationChange() returned immediately after calling StartConnection() and AddDevice(), which kick off background connection processes. If the dialog closed and the async chain completed too quickly, it would interrupt the connection before it could establish. Changes: - Add WaitUntilDeviceIsOnline() method that polls device status every 100ms with 10-second timeout - Update ReconnectAfterCommunicationChange() to wait for connection to establish before returning - Remove arbitrary 500ms delay from ManageViewModel as proper wait is now in service layer - Add 4 comprehensive tests validating the new wait behavior and settings preservation - Add test for standard Reconnect() method for completeness The reconnection now completes successfully regardless of dialog timing. All 83 tests passing. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- src/Core/Services/DeviceManagementService.cs | 46 +++++- src/Core/ViewModels/Pages/ManageViewModel.cs | 4 +- .../Services/DeviceManagementServiceTests.cs | 134 ++++++++++++++++++ 3 files changed, 178 insertions(+), 6 deletions(-) diff --git a/src/Core/Services/DeviceManagementService.cs b/src/Core/Services/DeviceManagementService.cs index 776dbc7..ea4d19e 100644 --- a/src/Core/Services/DeviceManagementService.cs +++ b/src/Core/Services/DeviceManagementService.cs @@ -243,9 +243,9 @@ private async Task WaitUntilDeviceIsOffline() { return; } - + using var cts = new CancellationTokenSource(_defaultShutdownTimeout); - + // Check if the connection exists before querying its status try { @@ -264,10 +264,47 @@ private async Task WaitUntilDeviceIsOffline() // Connection was already removed from the panel, which is fine during shutdown return; } - + await Task.Delay(TimeSpan.FromSeconds(1), cts.Token); } + private async Task WaitUntilDeviceIsOnline() + { + // Skip waiting if we don't have a valid connection + if (_connectionId == Guid.Empty) + { + return; + } + + using var cts = new CancellationTokenSource(TimeSpan.FromSeconds(10)); + + try + { + while (!cts.Token.IsCancellationRequested) + { + try + { + if (_panel.IsOnline(_connectionId, Address)) + { + return; + } + } + catch (KeyNotFoundException) + { + // Connection doesn't exist yet, keep waiting + } + + await Task.Delay(TimeSpan.FromMilliseconds(100), cts.Token); + } + } + catch (OperationCanceledException) + { + // Timeout occurred + } + + throw new TimeoutException("The device did not come online within the specified timeout."); + } + /// public event EventHandler?
