PR #351 只给 D2D 候选窗口加了滚轮翻页，WebView2 后端还没有。 网页端只上报一个以 WHEEL_DELTA 为单位的原始 delta，notch 累加仍然 交给 CandidateWheel::ConsumeWheelDelta，两个宿主最终都汇聚到 WM_PAGE_CANDIDATE，翻页逻辑一份不重复。Chromium 的 wheelDeltaY 本身 就是 ±120/格，正是原生累加器期望的单位，deltaY 作标准回退。 同时把滚轮翻页做成可配置的 general.paging_mouse_wheel，默认关闭： 候选宿主是 NOACTIVATE 且从不获得焦点，滚轮只有在 Windows「当我悬停 在非活动窗口上方时滚动它们」开启时才会送达，无法无条件承诺，所以设为 opt-in，设置页里也写明了这个前提。开关只在 WM_PAGE_CANDIDATE 一处 判断；D2D 那边在 WM_MOUSEWHEEL 顶部提前返回 false，关闭时消息照旧 交给 DefWindowProc，与功能加入前一致。
Product contracts
These headers are independently consumable C++17 contracts. Including them does not link the input engine, start threads, access dictionaries, or require any third-party code. The TSF text service consumes only these headers; the server consumes the same source by linking the engine. Both live in this repository — windows/ and server/ — and so does the engine, so one commit covers all three and there is no pin to keep in step.
windows_ipc.h owns the wire layouts, pipe names and opcodes. voice_composition_pipe.h owns voice framing. Consumers may wrap these headers but must not duplicate their definitions.
punctuation/policy.json is the source of truth for the ASCII punctuation keys and their Chinese
translations. Its generated policy.h is consumed by the engine and included directly by the hosts
that route punctuation keys. Stateful quote alternation and nested book-title marks remain
part of the same contract, rather than being re-created in each host.
product_lock.py contains the shared product-lock primitives used by the three platform locks.
See product_lock.md for the vendoring and byte-equality rule.
Main handshake
Reverse endpoints retain their 16-byte hello and PipeReady acknowledgement. Once both endpoints are registered, the new client sends the existing 304-byte ClientHello with:
| Field | Meaning |
|---|---|
| keycode | MSIP magic |
| wch | Major wire protocol version |
| point[0] | Minor additive version |
| modifiers_down | Supported capability bits |
| point[1] | Required capability bits |
| request_id | Nonzero registration correlation ID |
The Server sends ProtocolReady or ProtocolMismatch on the registered reply endpoint before activating the main route. The reply echoes the correlation ID and contains major/minor, negotiated capabilities and magic in the first six UTF-16 units. These packets are consumed only during registration and are never text commits.
Existing DLLs with unversioned hello remain accepted by the new Server using the established v1 semantics; they receive no new opcode. New DLLs require an acknowledgement from the new Server within the existing bounded handshake budget. Against an old or incompatible Server they remain disconnected and use the existing raw-input fallback, rather than interpreting unnegotiated frames. A late acknowledgement from an old registration cannot authorize another one.
Append opcodes; never change released values or reuse them. An incompatible layout needs a new major protocol and an explicit migration, not another copy of a header. Minor additions must be optional capabilities.
CharacterSetShortcut is optional and is not included in the default capability set.
Windows implementations that support it pass Capabilities | CharacterSetShortcut
to Hello / Negotiate. Only after negotiating this bit may a Chinese-mode client
consume Ctrl+Shift+F (no Alt or Windows modifier) and send the existing KeyEvent
with keycode F and Shift/Control modifier bits. The server toggles the persisted
character set without clearing composition, and refreshes the current candidate
page and toolbar. It sends no key reply. Clients suppress auto-repeat and must not
replay an ambiguously delivered toggle; older peers simply omit the optional bit.
tests/windows_ipc_contract.cpp executes wire-layout/upgrade/framing cases on all Engine CI platforms and both Windows TSF architectures.
