📝 WalkthroughWalkthroughA aplicação valida o armazenamento, impede instâncias simultâneas e configura o SQLite para concorrência. O aplicativo Tauri foi modularizado para iniciar o backend, gerenciar sessões, downloads, arquivos, splash screen e tray. A versão foi atualizada para ChangesRuntime do Devaulty
Estimated code review effort: 4 (Complex) | ~60 minutos Merge Risk: 🟠 High · up to This PR adds persistent storage validation, single-instance locking, tray-managed shutdown, and update downloads, but the current behavior can lose data in temporary directories, download from unintended hosts, expose incomplete update files, and leave the backend running after exit so future launches fail. The PR is not merge-ready until these lifecycle, validation, and cleanup issues are fixed. Sequence Diagram(s)sequenceDiagram

In `@backend/cmd/api/lock_windows.go`:
- Line 37: Atualize acquireSingleInstanceLock para incluir
syscall.LOCKFILE_FAIL_IMMEDIATELY nas flags passadas a syscall.LockFileEx,
preservando o bloqueio exclusivo e fazendo a segunda instância falhar
imediatamente quando o intervalo já estiver bloqueado.
In `@backend/cmd/api/main.go`:
- Around line 222-225: Atualize a validação em resolveDataDir para normalizar
absPath e os.TempDir() usando a mesma representação de caminho e rejeitar tanto
a igualdade quanto qualquer descendente do diretório temporário, incluindo
separadores específicos do Windows. Preserve as demais rejeições existentes para
caminhos contendo “.mount_” e “appimage”.
In `@frontend/src-tauri/src/commands.rs`:
- Around line 261-265: Ensure download failures clean up the partial target
file, not only cancellation. Update the DownloadCleanupGuard or both map_err
handlers around chunk downloading and file.write_all so network and write errors
remove target_path before returning, while preserving successful downloads and
existing cancellation behavior.
- Around line 232-236: Atualize a construção do reqwest::Client usada por
parsed_url para aplicar redirect::Policy::custom, validando o esquema e o host
de cada destino com a mesma função de allowlist da validação inicial. Preserve
um limite explícito para a cadeia de redirecionamentos, já que a política
customizada não o aplica automaticamente, e rejeite qualquer destino não
permitido antes de prosseguir com o download.
In `@frontend/src-tauri/src/lib.rs`:
- Around line 58-65: Ensure backend cleanup runs for every application exit path
by handling the Tauri runtime’s RunEvent::Exit and terminating the Go backend
there, rather than relying only on tray::quit_app. Update tray::quit_app to only
invoke app.exit(0), while preserving the existing window-hide behavior for
CloseRequested.

This pull request introduces significant improvements to both the backend and frontend of the application, focusing on robust single-instance locking, stable data directory resolution, enhanced backend process management, and new frontend features for user experience and update management. The changes span cross-platform backend locking, stricter data directory validation, a new system tray, download management, and improved communication between the Tauri frontend and Go backend.
Key changes include:
Backend Improvements
Single-instance locking:
Added platform-specific lock mechanisms (
lock_unix.go,lock_windows.go) to ensure only one instance of the backend runs per data directory, preventing data corruption or conflicts. [1] [2]Stable data directory resolution:
The
resolveDataDirfunction now rejects unstable paths (like AppImage mounts or temp directories), ensuring persistent storage is reliable and not ephemeral. Startup will fail if an unsuitable directory is detected. [1] [2]Frontend Enhancements
Backend process management and session state:
Extracted backend spawning logic to
backend.rs, including detection, preparation, and secure session handshake. IntroducedSessionStatefor robust in-memory communication of backend port/token and process lifecycle. [1] [2]System tray integration:
Added a system tray with "Open" and "Quit" actions. Closing the main window now hides it, and quitting via the tray ensures the backend process is properly terminated.
Download and update workflow:
Implemented secure, cancellable release file downloads, progress reporting, and safe file opening restricted to the downloads directory. Added environment reporting for update logic and AppImage support.
