Reflection
The idea is sound: --no-ask-password is a low-cost addition that prevents polkit from hijacking the TTY when no interactive agent is available. Combined with the existing isHeadlessSshSession() skip, it provides good defense-in-depth for the remaining Linux scenarios.
But the PR can't merge as-is. The diff only touches the test — the source code that actually constructs the systemd-inhibit command was never updated. This means the test will fail, and even if it passed, the flag wouldn't actually reach systemd-inhibit at runtime.
It's a one-line fix in the source file (sleepInhibitor.ts, ~line 258, add '--no-ask-password' to the args array). Once that's in and the PR template is filled in, this should be a quick merge.
Requesting changes for the missing source update.
中文说明
反思
思路是对的：--no-ask-password 是一个低成本的补充，可以在没有交互式 agent 时防止 polkit 劫持 TTY。与现有的 isHeadlessSshSession() 跳过机制结合，为其余 Linux 场景提供了良好的纵深防御。
但 PR 目前无法合并。diff 仅修改了测试——实际构造 systemd-inhibit 命令的源代码从未更新。这意味着测试会失败，即使测试通过，该标志也不会在运行时传递给 systemd-inhibit。
源码文件只需要一行改动（sleepInhibitor.ts，约第 258 行，在 args 数组中添加 '--no-ask-password'）。补上这个并填写 PR 模板后，应该可以快速合并。
请求修改，原因是缺少源码更新。

On Linux systems with a desktop environment, running qwen-code over SSH triggers a polkit authentication prompt from systemd-inhibit that corrupts the TUI input stream. Probe systemd-inhibit --help to detect whether --no-ask-password is supported, cache the result, and prepend the flag when spawning the inhibitor. Fixes QwenLM#5281

LGTM, looks ready to ship. ✅
✅ Real-build verification — fix behaves correctly (one minor, non-blocking note)I built the actual Honesty up front: this host is macOS, and the actual polkit prompt / TUI corruption is a Linux-only runtime behavior — I can't reproduce the live polkit interaction here. So I verified the real shipped logic via the class's own dependency-injection surface ( 1. Unit tests — 21/21 on PR head
2. Mutation test — the tests genuinely guard the fixReverted only 3. Behavioral A/B — real compiled
|
scenario (platform:'linux') |
PRE-FIX | FIXED (this PR) |
|---|---|---|
--help advertises the flag |
1 spawn, no probe, no --no-ask-password |
probe once → real args **--no-ask-password** --what=sleep … ✅ |
older systemd (--help lacks it) |
1 spawn, no flag | probe → graceful fallback, no flag |
| probe spawn errors (ENOENT) | 1 spawn, no flag | probe error → fallback, no flag |
acquire() ×3 |
— | 1 --help probe total (cached once per process) ✅ |
headless SSH (SSH_TTY, no DISPLAY) |
skipped (0 spawns) | skipped (0 spawns) — no regression |
So the fix probes once, prepends --no-ask-password when supported, falls back cleanly when not, caches the result, and still skips headless-SSH — exactly as designed.
Minor, non-blocking note (latent race introduced by the async probe)
The old start() was synchronous; the new one defers spawning until the async --help probe resolves. If acquire() is followed by release() inside that one-time probe window, release() drops activeCount to 0 and stop() is a no-op (this.child is still undefined), then the probe callback runs doStart() and spawns an inhibitor with activeCount === 0 — an orphaned systemd-inhibit (doStart has no activeCount guard). It's near-unreachable in practice (both acquire and release are driven by slow events — a user toggle or a seconds-long request lifecycle — not a sub-50 ms window) and dispose() cleans it up at shutdown, so not a blocker. A one-line guard would close it:
this.probeNoAskPassword(() => {
this.probing = false;
if (this.activeCount > 0) this.doStart(reason); // skip if released during the probe
});Verdict: correct, well-tested, no regression — LGTM. Worth considering the one-line activeCount guard above, but it's optional. 👍
中文说明（完整对应）
✅ 真实构建验证 —— 修复行为正确(一个次要、非阻塞的提示)
我在隔离 worktree 里从本 PR 的 head 构建了真实 core,并在 tmux 中驱动真实编译的 SleepInhibitor,对照 pre-fix 构建做 A/B。
先把话说清楚: 本机是 macOS,而真正的 polkit 弹窗 / TUI 损坏是 仅 Linux 的运行时行为 —— 我无法在这里复现真实的 polkit 交互。所以我通过这个类自带的依赖注入面({platform, env, spawn, logger})验证真实发布的逻辑:注入 platform:'linux' + 一个模拟 systemd-inhibit --help 的假 spawn,观察真实的参数/探测逻辑。(--no-ask-password 是 systemd 标准选项,systemd-inhibit 继承它,所以"跳过交互式 polkit 授权"这个前提是成立的。)
1. 单元测试 —— PR head 21/21
vitest run src/services/sleepInhibitor.test.ts → 21 passed(PR 把用例从 18 扩到 21)。撰写时 CI(Lint/CodeQL/Test×3)仍在跑。
2. 变异测试 —— 测试确实守住了修复
只把 sleepInhibitor.ts 回退到 base(保留 PR 测试):11/21 失败,含 3 个显式 --no-ask-password 测试,以及所有改用 vi.waitFor 等"探测→spawn"序列的测试(那些 ~1000ms 是超时 —— base 根本不会 spawn --help 探测)。
3. 行为 A/B —— 真实编译的 SleepInhibitor、模拟的 systemd(tmux)
场景(platform:'linux') |
PRE-FIX | FIXED(本 PR) |
|---|---|---|
--help 含该 flag |
1 次 spawn、无探测、无 --no-ask-password |
先探测一次 → 真实参数 **--no-ask-password** --what=sleep … ✅ |
旧 systemd(--help 无该 flag) |
1 次 spawn、无 flag | 探测 → 优雅降级,不加 flag |
| 探测 spawn 出错(ENOENT) | 1 次 spawn、无 flag | 探测出错 → 降级,不加 flag |
acquire() ×3 |
— | 总共只探测 1 次 --help(每进程缓存一次)✅ |
headless SSH(SSH_TTY、无 DISPLAY) |
跳过(0 spawn) | 跳过(0 spawn)—— 无回归 |
所以修复:探测一次、支持时前置 --no-ask-password、不支持时干净降级、缓存结果、且仍跳过 headless-SSH —— 完全符合设计。
次要、非阻塞提示(异步探测引入的潜在竞态)
旧 start() 是同步的;新的把 spawn 推迟到异步 --help 探测完成。如果 acquire() 之后在那一次性的探测窗口内紧接着 release(),release() 会把 activeCount 降到 0、而 stop() 是空操作(此时 this.child 还是 undefined);随后探测回调跑 doStart(),在 activeCount === 0 的情况下 spawn 出一个 inhibitor —— 一个孤儿 systemd-inhibit(doStart 没有 activeCount 守卫)。实践中几乎不可达(acquire 和 release 都由慢事件驱动 —— 用户开关或数秒级的请求生命周期,不是 50ms 级窗口),且 dispose() 会在退出时清理,所以不是阻塞项。一行守卫即可堵上:
this.probeNoAskPassword(() => {
this.probing = false;
if (this.activeCount > 0) this.doStart(reason); // 探测期间已 release 则跳过
});结论:正确、测试充分、无回归 —— LGTM。可以考虑上面那行 activeCount 守卫,但属可选。 👍

| Failing test | line | cause |
|---|---|---|
| starts systemd-inhibit on linux and stops it after the final release | 121 | bug #1 |
| skips systemd-inhibit for headless SSH sessions on Linux | 137 | bug #2 |
| ignores duplicate releases | 231 | bug #1 |
| restarts after an unexpected exit when acquired again | 288 | bug #1 |
| dispose kills the active child, resets state, and is idempotent | 313 | bug #1 |
| ignores a late error event from an already-replaced child | 405 | bug #1 |
(typecheck ✅ exit 0, eslint ✅, prettier ✅ — the failures are logic, not types.)
2. 🐞 Bug #1 — isRunning() is now always false
isRunning(): boolean {
- return this.child !== undefined;
+ return this.child !== undefined && this.probing;
}probing is set back to false before doStart() sets this.child, so after a successful start child !== undefined && probing = true && false = false. The method can never return true. This is an unrelated edit that breaks 5 tests. Fix: revert to return this.child !== undefined; (the && this.probing looks accidental).
3. 🐞 Bug #2 — the probe spawns even for headless-SSH sessions
start() runs the systemd-inhibit --help probe on Linux before the headless-SSH check in getCommand(). So a headless SSH session — where the inhibitor is intentionally skipped and nothing should spawn — now spawns an extra systemd-inhibit --help process. That breaks the "skips systemd-inhibit for headless SSH" contract (expect(spawn).not.toHaveBeenCalled()). Fix: gate the probe behind the same condition that decides systemd-inhibit will actually be used (i.e. don't probe when isHeadlessSshSession(env)).
4. ✅ What works — the actual fix (verified live in the real service)
I drove the real SleepInhibitor against a systemd-inhibit shim on PATH (real spawn, real probe + command construction). The shim records the exact argv and stands in for the inhibitor (no real sleep-block / polkit):
# SCENARIO: SSH session WITH a desktop (DISPLAY set) — the fix's target
systemd-inhibit --help
systemd-inhibit --no-ask-password --what=sleep --who=Qwen Code --why=verify-5318 --mode=block sleep infinity
^^^^^^^^^^^^^^^^^ the fix: prepended because the probe found support ✅
getActiveCount() = 1 isRunning() = false ← bug #1 visible live (child IS running)
# SCENARIO: real headless SSH (no DISPLAY) — inhibitor correctly skipped, but…
systemd-inhibit --help ← bug #2 visible live: the probe still spawned (old code spawned nothing)
The three feature-specific unit tests also pass: includes / omits / omits --no-ask-password for supported / unsupported / unavailable. So the core logic — including the graceful fallback on old systemd — is sound.
Recommendation
Good and useful fix (it solves the polkit-corrupts-TUI-over-SSH problem). Before merge, please:
- Revert
isRunning()toreturn this.child !== undefined;(bug pre-release: fix ci #1). - Skip the probe for headless-SSH (and generally when systemd-inhibit won't be used) so no extra process is spawned (bug Where is the config saved? #2).
- Re-run
vitest run src/services/sleepInhibitor.test.ts— all 21 should pass.

⚠️ 维护者验证 —— 核心修复是对的，但该 PR 跑不过自己的测试（请修复后再合并）
实际改动——探测 systemd-inhibit --help 并在前面加上 --no-ask-password——是正确的，在真实服务里也能工作。但 PR 还夹带了两个无关的回归，导致其 21 个测试里有 6 个失败（描述说"全部 18 个应通过"——实际是 21 个，其中 6 个失败）。建议：request changes——修掉这两个 bug 后就是个好功能。
环境
- 在 PR head（
041810df，基于当前main，MERGEABLE）上独立git worktree，全新npm ci。 - Linux · Node
v22.22.2· 本机真实的systemd-inhibit确实列出了--no-ask-password。
1. 测试套件 —— ❌ 6 失败 / 15 通过（共 21）
npx vitest run src/services/sleepInhibitor.test.ts → Tests 6 failed | 15 passed (21)
| 失败的测试 | 行 | 原因 |
|---|---|---|
| starts systemd-inhibit on linux and stops it after the final release | 121 | bug #1 |
| skips systemd-inhibit for headless SSH sessions on Linux | 137 | bug #2 |
| ignores duplicate releases | 231 | bug #1 |
| restarts after an unexpected exit when acquired again | 288 | bug #1 |
| dispose kills the active child, resets state, and is idempotent | 313 | bug #1 |
| ignores a late error event from an already-replaced child | 405 | bug #1 |
（typecheck ✅ 退出码 0，eslint ✅，prettier ✅ —— 失败是逻辑问题，不是类型问题。）
2. 🐞 Bug #1 —— isRunning() 现在恒为 false
isRunning(): boolean {
- return this.child !== undefined;
+ return this.child !== undefined && this.probing;
}probing 在 doStart() 设置 this.child 之前就被置回 false 了，所以一次成功启动后 child !== undefined && probing = true && false = false。该方法永远不可能返回 true。这是一处无关的改动，破坏了 5 个测试。修复： 改回 return this.child !== undefined;（&& this.probing 看起来是误加的）。
3. 🐞 Bug #2 —— 探测在 headless-SSH 会话下也会 spawn
start() 在 Linux 上会先跑 systemd-inhibit --help 探测，然后才在 getCommand() 里做 headless-SSH 判断。于是在 headless SSH 会话里——本该完全跳过、不 spawn 任何东西——现在会多 spawn 一个 systemd-inhibit --help 进程，破坏了"headless SSH 跳过 systemd-inhibit"的约定（expect(spawn).not.toHaveBeenCalled()）。修复： 把探测放到"确实会用 systemd-inhibit"的同一判断之后（即 isHeadlessSshSession(env) 时不要探测）。
4. ✅ 可用的部分 —— 实际修复（在真实服务里实测）
我用 PATH 上的 systemd-inhibit 垫片驱动了真实的 SleepInhibitor（真实 spawn、真实探测与命令构造）。垫片记录确切 argv，并代替真正的 inhibitor（不真正阻止休眠 / 不触发 polkit）：
# 场景：SSH 会话但有桌面（设置了 DISPLAY）—— 修复的目标场景
systemd-inhibit --help
systemd-inhibit --no-ask-password --what=sleep --who=Qwen Code --why=verify-5318 --mode=block sleep infinity
^^^^^^^^^^^^^^^^^ 修复：因为探测到支持，所以加在前面 ✅
getActiveCount() = 1 isRunning() = false ← bug #1 实地可见（子进程其实在运行）
# 场景：真实 headless SSH（无 DISPLAY）—— inhibitor 被正确跳过，但……
systemd-inhibit --help ← bug #2 实地可见：探测仍然 spawn 了（旧代码什么都不 spawn）
三个针对该功能的单测也通过：在支持 / 不支持 / 不可用时分别 包含 / 省略 / 省略 --no-ask-password。所以核心逻辑——包括在旧 systemd 上的优雅降级——是可靠的。
建议
是个有用的修复（解决了 SSH 下 polkit 破坏 TUI 的问题）。合并前请：
- 把
isRunning()改回return this.child !== undefined;（bug pre-release: fix ci #1）。 - headless-SSH 时跳过探测（以及通常在不会用到 systemd-inhibit 时），不要多 spawn 进程（bug Where is the config saved? #2）。
- 重新跑
vitest run src/services/sleepInhibitor.test.ts—— 21 个应全部通过。
- Revert isRunning() to return this.child !== undefined (probing flag was incorrectly ANDed, returning false after probe completed) - Skip --no-ask-password probe when systemd-inhibit won't be used (headless SSH sessions), avoiding unnecessary process spawn - Guard probe callback with activeCount > 0 to prevent orphaned child if dispose() is called during probe Fixes 6 failing tests in sleepInhibitor.test.ts

The prior critical issues are resolved in the latest head: isRunning() is back to the child-state check, headless SSH no longer runs the probe, and the probe callback now avoids starting an inhibitor after release/dispose. I rechecked the updated diff and did not find any new critical blocker.

What this PR does
Adds feature detection for
--no-ask-passwordin the sleep inhibitor. On firstacquire()on Linux, the code spawnssystemd-inhibit --helpand inspects the output to determine whether the flag is supported. The result is cached so the probe only runs once per process lifetime. When supported,--no-ask-passwordis prepended to thesystemd-inhibitarguments, preventing polkit from prompting for interactive authentication.Why it's needed
On Linux systems with a desktop environment, running qwen-code over SSH (without a local DE session) causes
systemd-inhibitto trigger a polkit authentication prompt (AUTHENTICATING FOR org.freedesktop.login1.inhibit-block-sleep). This prompt writes directly to the TUI's input stream, corrupting it and making the TUI unresponsive to user input. The--no-ask-passwordflag tellssystemd-inhibitto skip interactive authorization, which is the correct behavior for a headless/SSH session where no user is present to respond to the prompt.Reviewer Test Plan
How to verify
/settings.systemd-inhibitdoes not support--no-ask-password(older systemd), verify that sleep inhibition still works without the flag (graceful fallback).npx vitest run src/services/sleepInhibitor.test.ts— all 18 tests should pass.Evidence (Before & After)

Environment (optional)
Local Linux with systemd, Node.js v26.
Risk & Scope

中文说明
本 PR 做了什么
为 sleep inhibitor 添加了
--no-ask-password的特性检测。在 Linux 上首次调用acquire()时，代码会启动systemd-inhibit --help并检查输出以判断是否支持该标志。结果会被缓存，因此探测每个进程生命周期只运行一次。当支持该标志时，--no-ask-password会被添加到systemd-inhibit参数的前面，防止 polkit 弹出交互式认证提示。为什么需要
在带有桌面环境的 Linux 系统上，通过 SSH 运行 qwen-code（未登录本地桌面环境）会导致
systemd-inhibit触发 polkit 认证提示（AUTHENTICATING FOR org.freedesktop.login1.inhibit-block-sleep）。该提示直接写入 TUI 的输入流，导致 TUI 无法响应用户输入。--no-ask-password标志告诉systemd-inhibit跳过交互式授权，这对于没有用户在场响应提示的无头/SSH 会话是正确的行为。审查者测试计划
如何验证
/settings中启用"防止系统休眠"。--no-ask-password的系统上（较旧的 systemd），验证休眠抑制功能仍然正常（优雅降级）。npx vitest run src/services/sleepInhibitor.test.ts— 全部 18 个测试应通过。证据（修改前与修改后）
