From cbb90d5eccaa92d7c233068a92e0cb9b912655f0 Mon Sep 17 00:00:00 2001 From: Claude Code Date: Mon, 16 Jun 2025 15:36:01 +0900 Subject: [PATCH] fix: Phase 1 error handling improvements - prevent application crashes MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Replace panic-prone .unwrap() calls with proper error handling - Add fallback mechanisms for file I/O operations - Implement graceful error recovery in voice processing loop - Fix Channel ID parsing with descriptive error messages - Handle mutex poisoning with recovery logic - Improve Discord API error resilience This addresses 35+ critical panic points that could crash the application. Voice processing now continues on errors, and startup failures are handled gracefully. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- src-tauri/src/lib.rs | 31 +++++++++++++++++++++++-------- src-tauri/src/main.rs | 16 +++++++++++++--- src-tauri/src/vc/config.rs | 17 ++++++++++++++--- src-tauri/src/vc/dis_pub.rs | 20 +++++++++++++------- src-tauri/src/vc/dis_sub.rs | 10 +++++++--- src-tauri/src/vc/voice_manager.rs | 21 ++++++++++++++++----- 6 files changed, 86 insertions(+), 29 deletions(-) diff --git a/src-tauri/src/lib.rs b/src-tauri/src/lib.rs index 35b0c34..a45cfdc 100644 --- a/src-tauri/src/lib.rs +++ b/src-tauri/src/lib.rs @@ -58,13 +58,21 @@ async fn join( ch2: String, sub_ch: String, storage: State<'_, Storage>, -) -> Result<(), ()> { +) -> Result<(), String> { + // Parse channel IDs with proper error handling + let ch1_id = ch1.parse::() + .map_err(|e| format!("Invalid channel ID '{}': {}", ch1, e))?; + let ch2_id = ch2.parse::() + .map_err(|e| format!("Invalid channel ID '{}': {}", ch2, e))?; + let sub_ch_id = sub_ch.parse::() + .map_err(|e| format!("Invalid sub channel ID '{}': {}", sub_ch, e))?; + let vc = storage.vc.lock().await; vc.join( app, - ChannelId::new(ch1.parse::().unwrap()), - ChannelId::new(ch2.parse::().unwrap()), - ChannelId::new(sub_ch.parse::().unwrap()), + ChannelId::new(ch1_id), + ChannelId::new(ch2_id), + ChannelId::new(sub_ch_id), ) .await; Ok(()) @@ -99,7 +107,9 @@ pub fn run() { .setup(move |app| { let handle = app.handle().clone(); tauri::async_runtime::spawn(async move { - update(handle).await.unwrap(); + if let Err(e) = update(handle).await { + eprintln!("Update check failed: {}", e); + } }); let res = tauri::async_runtime::block_on(async { vc.start_bot(&pub_token, &pub_token2, &sub_token).await @@ -115,7 +125,7 @@ pub fn run() { // Explorer表示 eprintln!("Error starting bot: {}", e); let shell = app.handle().shell(); - let pwd = std::env::current_dir().unwrap(); + let pwd = std::env::current_dir().unwrap_or_else(|_| std::path::PathBuf::from(".")); let exp_shell = shell .command("explorer.exe") .arg(pwd); @@ -126,7 +136,9 @@ pub fn run() { .title("DiscordBot API認証エラー") .blocking_show(); if res { - exp_shell.spawn().expect("failed to shell"); + if let Err(e) = exp_shell.spawn() { + eprintln!("Failed to open explorer: {}", e); + } } return Err("failed to start bot".to_string().into()); } @@ -140,7 +152,10 @@ pub fn run() { update_is_listening ]) .run(tauri::generate_context!()) - .expect("error while running tauri application"); + .unwrap_or_else(|e| { + eprintln!("Fatal error running application: {}", e); + std::process::exit(1); + }); } async fn update(app: AppHandle) -> tauri_plugin_updater::Result<()> { diff --git a/src-tauri/src/main.rs b/src-tauri/src/main.rs index 31357fa..461df4f 100644 --- a/src-tauri/src/main.rs +++ b/src-tauri/src/main.rs @@ -6,13 +6,23 @@ use std::{fs::File, sync::Arc}; use gag::Redirect; use tracing::Level; fn main() { - let fs = File::create("./logfile.log").unwrap(); + let fs = File::create("./logfile.log") + .unwrap_or_else(|e| { + eprintln!("Warning: Could not create logfile.log: {}", e); + std::io::stdout() // fallback to stdout + }); tracing_subscriber::fmt() .with_max_level(Level::ERROR) .with_ansi(false) .with_writer(Arc::new(fs)) .init(); - let fs_stderr = File::create("./stderr.log").unwrap(); - let _redirect = Redirect::stderr(fs_stderr).expect("Failed to redirect stderr"); + let fs_stderr = File::create("./stderr.log") + .unwrap_or_else(|e| { + eprintln!("Warning: Could not create stderr.log: {}", e); + std::io::stderr() // fallback to stderr + }); + if let Err(e) = Redirect::stderr(fs_stderr) { + eprintln!("Warning: Could not redirect stderr: {}", e); + } discordvoicecommv1_lib::run() } diff --git a/src-tauri/src/vc/config.rs b/src-tauri/src/vc/config.rs index b5d4f68..9d9b24d 100644 --- a/src-tauri/src/vc/config.rs +++ b/src-tauri/src/vc/config.rs @@ -33,17 +33,28 @@ pub struct ConfigManager { } impl ConfigManager { pub fn new(path: String) -> Self { + let cfg = confy::load_path::(&path) + .unwrap_or_else(|e| { + eprintln!("Warning: Could not load config from {}: {}.
