Real, scoped gap this closes - not a nice-to-have: `docs/TODO.md`'s +//! "ydotool's `--absolute` is unusable on this machine" entry and the +//! "wl_pointer motion/button coordinates" investigation both trace back to +//! the same root problem, that this compositor had no real protocol path +//! for synthetic pointer input at all. `ydotool`'s own uinput device has +//! no `EV_ABS` capability on this hardware (relative-only, and libinput's +//! pointer-acceleration curve warps even that), which is why every +//! synthetic-click verification this project has ever done needed a +//! fragile corner-clamp-then-walk workaround instead of a precise, +//! reliable placement. A virtual pointer client (a `wlrctl`/custom tool +//! built against this protocol, or a future `ydotool` that speaks it) +//! sidesteps all of that: `motion_absolute` lands exactly where asked, and +//! `motion` (relative) is a raw compositor-space delta with no libinput +//! acceleration applied, since it never touches a uinput device at all. +//! +//! Every request is fed through the exact same `handle_pointer_position`/ +//! `handle_pointer_button` entry points a real libinput hardware event +//! goes through (`udev/session.rs::handle_libinput_event`) - a virtual +//! pointer is indistinguishable from a real mouse to every other part of +//! this compositor (hit-testing, drag/resize, focus-follows-mouse, all of +//! it), by construction, rather than a second, easily-drifting code path. +//! +//! Scroll is the one piece that can't reuse an existing entry point: real +//! scroll handling (`udev/session.rs`'s `InputEvent::PointerAxis` arm) +//! reads its values through smithay's `PointerAxisEvent` trait, which is +//! implemented for real backend event types, not something a synthetic +//! caller can construct. Built directly against `AxisFrame` instead (the +//! same builder that trait ultimately feeds into) - accumulated across +//! this protocol's own `axis`/`axis_source`/`axis_stop`/`axis_discrete` +//! requests exactly as the protocol groups them, and committed on `frame`. +//! +//! One real limitation, not silently glossed over: unpinned motion is only +//! ever applied when `CompState::udev` is live (the real-hardware +//! backend). The winit/nested backend has no equivalent multi-monitor +//! `bounds()` to clamp against and no daily-driver use case for synthetic +//! input, so a virtual pointer bound there is accepted (the global still +//! exists, a client's `create_virtual_pointer` still succeeds) but its +//! unpinned motion requests are no-ops - documented here rather than +//! silently dropped with no explanation, matching this codebase's own +//! "degrade honestly" convention elsewhere (`monitor_layout::load`, +//! `icon_theme::find_icon`). Pinned motion (below) has no such limitation +//! - it never touches `udev`/`bounds()` at all, so it works identically +//! on both backends, which is what makes the winit/nested backend a real +//! place to validate it. +//! +//! **Phase 2 of this project's own multi-cursor plan** (see +//! `docs/TODO.md`'s "Multi-cursor Phase 2" entry for the full reasoning): +//! pinning a virtual pointer object to a specific window so its +//! motion/button events reach that window directly, independent of +//! wherever the shared seat's real focus/`pointer_pos` currently is. This +//! is the concrete answer to "an agent could operate one window while the +//! user works another, genuinely simultaneously" - confirmed against +//! smithay 0.7.0's own source that a second `wl_seat` would be invisible +//! to every real client (GTK/Qt/Electron only ever bind the first one +//! advertised), so the fix has to work *through* the one seat every +//! client already binds, not around it. +//! +//! `CompState::set_virtual_pointer_pin` (queued via a `pin_input`/ +//! `unpin_input` IPC dispatch, `crates/platform/src/ipc.rs`, and drained +//! the same one-poll-tick-later way `set_output_position` already is) +//! finds every virtual pointer object owned by a given client pid -- +//! `Client::get_credentials` - and sets its `pinned_window`. A pid, not +//! an opaque per-object id, is the pinning handle: nothing outside this +//! compositor could ever learn a `zwlr_virtual_pointer_v1` object's own +//! internal id to pass back in, whereas a controlling tool already knows +//! its own pid (`std::process::id()`) for free. +//! +//! A pinned object's `motion`/`motion_absolute`/`button` requests bypass +//! `handle_pointer_position`/`handle_pointer_button` entirely - they +//! never move `pointer_pos`, change focus, or raise the target window. +//! Instead they hand-roll the real `wl_pointer.enter`/`motion`/`button`/ +//! `frame`/`leave` wire messages directly against every `WlPointer` +//! resource the target surface's own client has bound +//!
