Summary

  • sudo / su(含 /usr/bin/sudo)不再经 split_whitespace() 拆开再拼接,确认与提交给 PTY 的都是用户原始命令。
  • 主 readline 与 slash / @ 弹窗恢复共用 dispatch_builtin_line,弹窗入口会真正执行并记录 PTY 退出码。
  • 被安全策略拦住的 builtin 只记退出码 1,不再追加一条退出码 0。

Test plan

  • cargo test -p aish-shell --lib commands::tests
  • cargo test -p aish-shell --lib privilege_dispatch_tests
  • cargo test -p aish-shell --test shell_integration_test
  • cargo fmt --all -- --check
  • cargo clippy --all-targets -- -D warnings
  • 在交互 shell 里执行 sudo printf '%s\n' 'a b',确认输出保留两个空格
  • 从 slash 或 @ 弹窗恢复后提交 sudo id,确认命令实际执行且历史退出码不是固定的 0

Summary by CodeRabbit

  • Bug Fixes
    • Privilege commands such as sudo and su are handled consistently, including when invoked by absolute path.
    • Commands submitted during popup recovery now receive the same checks and handling as commands submitted in the main shell, preventing blocked commands from being recorded as successful.
    • Original command text, including quoting and escaped spaces, is preserved when requesting confirmation and running privilege commands.

…l-Team#546)

Popup recovery skipped route_to_pty and the builtin path rejoined tokens, so quoted spaces were lost and a command could be recorded as success without running.
…#546)

screen_shell_command already stores exit code 1. A second history row with exit code 0 made a blocked cd or export look successful.

📝 Walkthrough

Walkthrough

Privilege commands are recognized by basename and retain their trimmed original text for PTY execution. Both the main readline loop and popup-recovery submissions now use shared builtin dispatch, including command screening, PTY routing, context updates, and history recording.

Changes

Privilege command dispatch

Layer / File(s) Summary
Privilege command recognition and line handling
crates/aish-shell/src/commands.rs, crates/aish-shell/src/input.rs
Privilege commands are detected by basename, including absolute paths. Their plans preserve the trimmed original command text. Input classification and builtin dispatch route these commands through the privilege-command path. Tests cover command planning, text preservation, absolute paths, and classification.
Shared readline dispatch
crates/aish-shell/src/app.rs
The main loop and popup-recovery path delegate builtin handling to dispatch_builtin_line. The dispatcher screens commands, routes approved commands to the PTY, updates LLM context, and records history. Linux tests cover blocked and executed commands.

A rabbit checks each command line,
Keeps every quoted space in line.
Through popup paths the commands go,
Screened before the shells can flow.
The PTY returns, the logs take note,
Then rabbit hops off with a carrot.

Track PTY failures for sudo and su.

execute_external_command updates last_exit_code, so the prompt exit status is not stale. However, the PTY branch does not update last_command or can_correct_error. A failed sudo or su command therefore does not enable ; quick-fix or /diagnose, and those flows can retain an older command state. Before this PR, /usr/bin/sudo used the Command path and called track_command_failure_state.

Suggested fix
             self.record_history(input, exit_code);
             self.reset_interruption();
+            self.track_command_failure_state(&command, exit_code);
             return false;
