From 2c2a14d597691142a95471a4c7e0651e22153afb Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Sun, 19 Apr 2026 15:47:16 +0000 Subject: [PATCH 1/5] Fix Steam installed-game path resolution for placeholder manifests This change improves how the launcher resolves game installation directories from Steam manifests. It no longer blindly trusts the `installdir` field, which can sometimes contain placeholder values like "App ". Key changes: - Added `is_suspicious_installdir` to identify placeholder directory names. - Generalized `probe_install_dir_by_appid` in `src/utils.rs` to find installation directories using `steam_appid.txt` or partial name matches. - Updated library scanning in `src/library.rs` to validate manifest paths and fall back to probing if they are suspicious or missing. - Enhanced `InstalledAppInfo` and `LocalGame` models with diagnostic fields to track how the installation directory was resolved. - Refactored `src/steam_client.rs` to use the unified probing logic. - Added regression tests in `tests/repro_issue.rs`. - Replaced `println!` with `tracing::info!` and optimized string handling.
