Summary by CodeRabbit
Walkthrough新增 Windows DualSense sidecar。Sunshine Core 通过命名管道管理 DS5 会话，并支持输入、触觉反馈和设备状态传输。构建流程新增 .NET sidecar 发布、运行时校验和 Windows 安装打包。 ChangesWindows DualSense sidecar
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to This PR adds optional DualSense sidecar and haptics support, but concurrent gamepad requests may race, the elevated IPC endpoint may permit unintended local access, and a cancellation test can pass without exercising the intended blocked-read path. These bounded correctness, security, and validation issues should be fixed or explicitly accepted before merge. Possibly related PRs

2530-2546: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick win每次调用都写入共享的静态 vector，会与并发读取产生数据竞争。
supported_gamepads返回静态gps的引用。改动之后，每次调用都会在第 2541-2545 行覆盖gps的全部元素。Web UI 的 HTTP 处理使用线程池，多个请求可以并发进入该函数。一个线程写入gps元素时，另一个线程可能正在通过之前返回的引用读取同一元素，这是数据竞争。另外第 2530-2536 行的初始化列表与第 2541-2545 行的赋值完全重复，
ds5_enabled的判断写了两次。建议用互斥量保护刷新逻辑，并删除重复的初始化值：
♻️ 建议修复
// ds4 == ps4 - static std::vector gps { - supported_gamepad_t { "auto", true, reason }, - supported_gamepad_t { "x360", enabled, reason }, - supported_gamepad_t { "ds4", enabled, reason }, - supported_gamepad_t { "ds5", ds5_enabled, ds5_enabled ? "" : "gamepads.ds5-sidecar-not-available" }, - supported_gamepad_t { "switch", switch_enabled, switch_reason } - }; - - // This function is queried after runtime configuration changes too. Keep - // the stable backing vector (the API returns a reference), but refresh its - // values instead of freezing the first observed driver/component state. - gps[0] = { "auto", true, reason }; - gps[1] = { "x360", enabled, reason }; - gps[2] = { "ds4", enabled, reason }; - gps[3] = { "ds5", ds5_enabled, ds5_enabled ?

"" : "gamepads.ds5-sidecar-not-available" }; + gps[4] = { "switch", switch_enabled, switch_reason };返回引用的接口本身无法完全消除竞争。如果调用方允许，更好的做法是改为按值返回
std::vector<supported_gamepad_t>。按路径说明的要求：“Sunshine 核心 C++ 源码……审查要点：内存安全、线程安全、RAII 资源管理、安全漏洞。”

Inline comments:
In `@docs/windows_dualsense_component_lifecycle.md`:
- Around line 178-188: Update the “测试虚拟 DualSense” test-session flow to branch
on the profile: skip four-channel audio endpoint and PCM checks for the
“dualsense” profile, report audio as unsupported, and retain endpoint waiting
and PCM validation for “dualsense-composite” and other applicable profiles.
Preserve the existing HID/input lifecycle and cleanup behavior.
- Line 642: 修正“截至 2026-08-14”的验证记录日期：若首期实现已完成，填写实际完成日期；若尚未完成且计划于 2026-08-14
完成，将该表述明确标记为计划事项。
- Around line 317-325: Update the ds5-status-changed event contract to emit only
complete Ds5StatusSnapshot payloads in v1, removing the ambiguous allowance for
revisioned deltas. Keep revision-based stale-event handling consistent with this
full-snapshot-only model so polling responses cannot overwrite newer event
updates.
- Around line 105-107: 在文档中补充 authored PCM 与 fallback 仲裁的协议状态机，明确 active
source、单一 owner、静音切换、断包超时、滞回以及恢复规则；确保 PCM 活跃时停止普通音频合成，并避免因单个空包抖动切换。定义并覆盖 PCM
开始、静音、断序和 fallback 恢复场景的行为，同时保留独立开关、增益和 native-packet arbitration 约束。
- Line 46: 在 Windows 安装与兼容性验证流程中补充已验证的 Windows 10/11 OS build 矩阵，并在安装前校验当前系统
build；对不在支持矩阵内的系统明确拒绝安装。更新相关支持状态或冻结决策，确保未经验证的 Windows 10 环境不会被标记为受支持。
- Around line 348-355: 更新协议文档中的授权要求：将操作系统命名管道身份绑定到连接及 session，不能信任客户端提交的
process_identity；为 attach、update_input、subscribe_output 和 get_status
增加授权检查，并保留对非所有者 detach 与 shutdown 的拒绝要求。
- Line 56: 在该生命周期章节补充 Core 崩溃清理机制：记录 Job Object 的
JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE、owner Named Pipe 断开时销毁连接创建设备，并明确
EOF、broken-pipe IOException、半开连接和 owner 失联的处理边界；扩展 ProtocolSelfTest，在
client.Dispose() 前不执行 detach，模拟仍有设备时的 Core 崩溃或 Pipe 断开，并断言 Sidecar 退出且虚拟设备已释放。
In `@src/config.cpp`:
- Around line 1502-1504: 更新 ds5_sidecar_path 的解析逻辑：仅当 input.ds5_sidecar_path
非空时使用 path_f，并沿用 platf::appdata() 规则；为空时保持空值，不要让默认路径导致 configured() 返回 true。修改
string_f(vars, "ds5_sidecar_path", ...) 这一处，保留其他 DS5 配置处理不变。
In `@src/platform/windows/ds5/ds5_sidecar_client.cpp`:
- Around line 330-348: 调整 close() 中管道资源的释放顺序：保留 CancelIoEx(pipe, nullptr)，先通过
reader.join() 等待读线程退出，再调用 CloseHandle(pipe) 并将 pipe 设为 INVALID_HANDLE_VALUE。保持
stopping、online 及进程清理逻辑不变；仅确认现有 WaitForSingleObject(process, 5000)
的阻塞行为符合清理路径要求。
In `@src/platform/windows/input.cpp`:
- Around line 1915-1923: Update the DualSense branch in alloc_gamepad_internal
to retain the result of raw->ds5_sidecar->alloc before moving feedback_queue,
then request motion events with make_motion_event_state at the same 100 Hz rate
as the DS4 path after successful allocation. Return the allocation result while
preserving the existing unavailable-sidecar failure behavior.
In `@src/stream.cpp`:
- Around line 1400-1457: Ensure DS5 PCM feedback is dispatched within 5 ms by
updating the control-loop scheduling around the ds5_haptics_pcm handling and the
unreliable send path: add the established feedback-queue wakeup mechanism, or
cap the control thread’s iterate wait to 5 ms while DS5 PCM is active, so
packets are not accumulated during the 150 ms wait.
In `@tools/sunshine-ds5-sidecar/ControllerSession.cs`:
- Around line 128-135: 更新 ControllerSession 中的触摸事件分支，使事件类型
5（LI_TOUCH_EVENT_BUTTON_ONLY）被视为合法的无触点状态变化更新并直接忽略；保留现有 2、4、6 的触点移除处理及对其他未知类型抛出
InvalidDataException 的行为。
- Around line 263-280: Update EmitHaptics and the SensorTimestamp calculation to
avoid overflow by dividing elapsed ticks before multiplying to microseconds,
preserving accurate timestamps. Make _hapticsSequence an int or long and use
Interlocked.Increment when assigning it in EmitHaptics so concurrent callbacks
cannot produce duplicate sequence numbers.
In `@tools/sunshine-ds5-sidecar/SidecarServer.cs`:
- Around line 204-214: Update Emit to route messages by Protocol.MessageType
rather than RequestId: send only HapticsPcm through the bounded, lossy
_realtimeOutgoing channel, and send Rumble, AdaptiveTriggers, Led, errors, and
other non-PCM messages through _controlOutgoing. Preserve the existing wakeup
signaling behavior.
- Around line 38-47: Update the NamedPipeServerStream creation in the
SidecarServer pipe setup to use NamedPipeServerStreamAcl.Create with an explicit
ACL allowing only the Sunshine service identity, SYSTEM, and Administrators;
include PipeOptions.FirstPipeInstance alongside the existing options, and add
the required System.IO.Pipes.AccessControl assembly reference.

Learning: 在 `src/platform/windows/input.cpp` 的 Windows 虚拟鼠标滚轮处理里，`set_mouse_mode()` 仅切换注入模式，并不销毁 `vmouse::device_t`。当虚拟滚轮发送失败或 `scroll()` / `hscroll()` 改走 `SendInput` 时，应丢弃对应的 `vmouse_vscroll_accum` / `vmouse_hscroll_accum`，而非将旧累计量转发到另一注入后端，以避免跨后端输入顺序错乱和延迟重放。

1405-1444: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win在序列化边界校验 PCM 长度。
encrypted_payload只按 240 帧分配，但data.frame_count直接控制plaintext大小和std::copy_n()长度。encode_control()不检查输出容量。当前 sidecar 路径限制了frames <= 240，但此函数仍应拒绝越界数据，避免未来新增生产者时发生缓冲区越界或payloadLength截断。建议在分配

apply_config()在读取完整配置失败时使用unwrap_or_default()，随后只带 3 个 DS5 字段调用完整配置保存接口；后端update_full_config()会以请求内容重建配置文件，因此一次读取失败就可能删除除受保护字段外的其他设置。这里应直接传播读取错误，不能用空配置继续保存：https://github.com/qiin2333/sunshine-control-panel/blob/2f9b839dedc38607fb855fca8b6098060e378f6e/src-tauri/src/dualsense.rs#L344-L365 audio_haptics默认开启，但dualsense_set_config()只验证 profile 存在，不检查usbip_available；界面也只禁用了 composite 自测，没有禁止保存该配置。USB/IP 不可用时会把用户带入一个已知无法创建 composite 控制器的配置。建议保存时拒绝并说明缺少传输组件，或明确回退到 HID-only。
以上是静态审查结论；CI 的 Windows 构建已通过，但现有自测没有覆盖 Core 侧正常 free_gamepad() 的关闭路径。

- Around line 24-25: 更新
tests/unit/platform/windows/test_ds5_sidecar_client.cpp#L24-L25，在计时并调用
client.free(0) 前等待 fake sidecar 确认客户端已处理后续消息并重新进入阻塞读取循环。更新
tests/tools/ds5_fake_sidecar.cpp#L75-L90，增加测试协议消息或同步信号以暴露该状态，并让测试正确等待和断言该同步条件。
- Around line 14-22: 在测试中为全局配置 ds5_enabled 和 ds5_sidecar_path 引入 RAII scope
guard，确保 test_ds5_sidecar_client 中 client.alloc 相关断言失败提前退出时也能恢复 previous_enabled
和 previous_path；保留现有断言行为，并让正常返回和断言失败路径都执行恢复。

已补强阻塞读取回归（aa4a566f4）：测试通过命名事件确认 reader 首次进入 overlapped ReadFile，fake sidecar 再发送 marker；Core 消费 marker 后，测试等待 reader 第二次进入阻塞读取，才开始计时 free()。配置和事件句柄均改为 RAII，当前实测 72 ms。未手动 resolve review thread，留给 reviewer 复核。 |
|
最终 CI 已通过（run 31769279725）：Windows full build、native tests（含 aggregate test_sunshine 与 standalone DS5 regression）、打包和 artifact 上传全部成功。此前首次失败为 MSYS2 镜像超时；后续发现并修复了独立测试目标缺 Boost::format，以及 aggregate 目标未启用 test-only reader hook。 |

a2e17a648。上游采用libvirtualhid统一输入后端；本 PR 未直接移植该后端，而是在 Windows 上保留现有 ViGEm X360/DS4 路径，通过可选 sidecar 实现 DualSense。改了啥呀
moonlight-audio-haptics分析捕获的 PCM，通过固定 72-byte IR v2 发送设备无关的双通道触觉特征，由 Moonlight 负责终端映射与渲染。moonlight-audio-haptics已作为本 PR 的正式依赖集成并固定到已合入的 SDK PR 锁屏时连接后再断开会导致图标卡住，无法点击以唤起托盘菜单。 #3 merge commit；IR-v2 分析链路属于当前验收范围，不再是后续占位。为啥要改
ViGEm 继续负责它擅长且已有成熟签名覆盖的 X360 / DS4；DualSense 的复合 HID 与四声道触觉则隔离到独立组件。这样即使 DS5 组件缺失、损坏或启动失败，也不会扩大现有用户的风险面，GUI 还能统一完成安装、修复和卸载，笨蛋状态也有明确恢复路径啦。
