From 251f1d65f3c115f58b5dccfe0e8a49c38710c993 Mon Sep 17 00:00:00 2001 From: openhands Date: Mon, 22 Jun 2026 17:43:24 +0000 Subject: [PATCH] feat: Add repair/reinstall capability for master Steam prefix - Add repair_master_steam() function that: - Stops running Steam/wine processes in master prefix - Backs up existing prefix to master_steam_prefix.bak. - Keeps only 1 previous backup (deletes oldest before creating new) - Re-runs install_master_steam() against fresh prefix - Add UI components: - 'Repair / Reinstall Windows Steam Runtime' button in Settings - Confirmation dialog warning about Steam login state - Progress/status updates via AsyncOp channel - Add post-launch grace period health check in WineTkgRunner: - 2-second grace period after ready-signal detection - Polls try_wait() to verify Steam process still alive - Detects false-positive scenario where ready-signal exists but process has crashed (e.g., steamerrorreporter appeared) - Error message suggests using repair action - Add unit test for grace-check behavior - Fix borrow checker issues in UI confirmation dialog - Fix type mismatch in readiness loop (Option vs bool) Co-authored-by: openhands --- src/infra/runners/wine_tkg.rs | 64 +++++++++++-- src/launch/mod.rs | 104 +++++++++++++++++++++ src/launch/verification_tests.rs | 146 ++++++++++++++++++++++++++++- src/ui.rs | 155 +++++++++++++++++++++++++++++++ 4 files changed, 460 insertions(+), 9 deletions(-) diff --git a/src/infra/runners/wine_tkg.rs b/src/infra/runners/wine_tkg.rs index b35cc17..3afb2fb 100644 --- a/src/infra/runners/wine_tkg.rs +++ b/src/infra/runners/wine_tkg.rs @@ -303,7 +303,9 @@ impl Runner for WineTkgRunner { let steam_config_vdf = prefix_steam_dir.join("config/config.vdf");
