From 563f12caa1341d81e1eb3f7d566dc441de0d34bb Mon Sep 17 00:00:00 2001 From: lincube Date: Tue, 12 May 2026 08:35:48 +0800 Subject: [PATCH] Add install checkpoint/resume and DDSS workflows Introduce install checkpoint support and resume logic for updates, plus related locking and validation. Adds InstallCheckpoint model, AppJsonContext serialization, and UpdatePaths helpers for deployment lock, apply-in-progress lock and install-checkpoint path. UpdateEngineService gains checkpoint load/save/delete, incoming-state validation, resume logic for PLONDS and legacy updates, apply lock handling, and safer cleanup; ApplyPendingPlondsUpdateAsync and ApplyPendingUpdate flow updated accordingly. Add DeploymentLock contract and extend UpdateState with pause/resume/cancel helpers. Tests updated to cover stale/valid checkpoint resume and legacy/PLONDS flows. CI: enhance ddss-publish to detect release channel, validate S3 assets, prepare and atomically publish channel pointer; add ddss-rollback workflow to publish rollbacks; adjust plonds-build concurrency and release events. --- .claude/settings.local.json | 7 +- .github/workflows/ddss-publish.yml | 106 +- .github/workflows/ddss-rollback.yml | 146 ++ .github/workflows/plonds-build.yml | 5 + LanMountainDesktop.Launcher/AppJsonContext.cs | 1 + .../Models/UpdateModels.cs | 19 + .../Services/UpdateEngineService.cs | 547 ++++-- .../Update/DeploymentLock.cs | 11 + .../Update/UpdatePaths.cs | 16 +- .../Update/UpdateState.cs | 19 +- .../UpdateSystemRegressionTests.cs | 211 ++- LanMountainDesktop/App.axaml.cs | 200 ++- .../FusedDesktopEditGridAdapter.cs | 73 + .../Models/FusedDesktopLayoutSnapshot.cs | 12 + .../Settings/SettingsDomainServices.cs | 1 - .../Services/Update/DeploymentLockService.cs | 52 + .../Services/Update/UpdateDownloadEngine.cs | 48 +- .../Services/Update/UpdateInstallGateway.cs | 69 +- .../Services/Update/UpdateOrchestrator.cs | 272 ++- .../Services/UpdateWorkflowService.cs | 1572 ----------------- .../Services/WindowPassthroughService.cs | 665 ++++--- .../ViewModels/SettingsViewModels.cs | 1033 ----------- .../ViewModels/UpdateSettingsViewModel.cs | 58 +- .../Views/DesktopWidgetWindow.axaml.cs | 17 +- .../FusedDesktopComponentLibraryControl.axaml | 143 +- ...sedDesktopComponentLibraryControl.axaml.cs | 12 +- .../FusedDesktopComponentLibraryWindow.axaml | 98 +- ...usedDesktopComponentLibraryWindow.axaml.cs | 119 +- .../Views/MainWindow.SettingsHardCut.Stubs.cs | 19 +- .../SettingsPages/UpdateSettingsPage.axaml | 556 +++--- .../SettingsPages/UpdateSettingsPage.axaml.cs | 9 +- .../Views/TransparentOverlayWindow.axaml | 63 +- .../Views/TransparentOverlayWindow.axaml.cs | 1251 ++++++++----- 33 files changed, 3231 insertions(+), 4199 deletions(-) create mode 100644 .github/workflows/ddss-rollback.yml create mode 100644 LanMountainDesktop.Shared.Contracts/Update/DeploymentLock.cs create mode 100644 LanMountainDesktop/DesktopEditing/FusedDesktopEditGridAdapter.cs create mode 100644 LanMountainDesktop/Services/Update/DeploymentLockService.cs delete mode 100644 LanMountainDesktop/Services/UpdateWorkflowService.cs diff --git a/.claude/settings.local.json b/.claude/settings.local.json index d7300de..b378090 100644 --- a/.claude/settings.local.json +++ b/.claude/settings.local.json @@ -2,7 +2,12 @@ "permissions": { "allow": [ "Bash(ls -la \"/d/github/LanMountainDesktop/.claude/worktrees/agent-a4c5412322421ab67\" && ls -la \"/d/github/LanMountainDesktop\" && ls -la \"/d/github\")", - "Read(//d/github/**)" + "Read(//d/github/**)", + "Bash(dotnet build *)", + "Bash(dotnet test *)", + "Bash(python -)", + "Bash(py -3 -c \"from pathlib import Path;
