From 681d7daf659766c24d9222acfab63eeff09de6ce Mon Sep 17 00:00:00 2001 From: can1357 Date: Fri, 24 Jul 2026 02:23:56 +0200 Subject: [PATCH] feat(computer): unified native addon, /computer toggle, function tool - Replaced the separate GUI-linked pi_natives.desktop.linux-x64 addon with a pure-Rust X11 backend (x11rb RustConnection capture via RandR/GetImage, XTest input with keysym mapping) compiled into the core addon on every published target; Linux arm64 and musl are now supported and headless hosts load the addon unaffected. - Removed the native-desktop-linux cargo feature, desktop_unsupported.rs, lazy desktop loader, second napi build, desktop packaging/CI steps, GUI build dependencies, and the now-unreferenced vendored libspa crate; reverted setup-system-deps to main. - Preserved the desktop input hardening semantics on the unified backend: XTest layouts reject negative origins and coordinates beyond 0..=32767, batch coordinates stay bound to the frame last returned to JS with intermediate screenshots deferred, coordinate input requires a previously returned frame, and failed chord releases still release every held key. - Enforced a 60s worker-side execute deadline (DESKTOP_DEADLINE_EXCEEDED): no input is emitted after expiry and wait-heavy batches are rejected upfront. - Added int32 fail-closed validation for coordinates, drag points, and scroll deltas at the JS ingress and gateway schema. - Exposed computer to models without native OpenAI computer-use support as a regular function tool with a typed GA action schema across OpenAI, Azure, and Codex Responses providers, including named forced choice. - Added the /computer slash command (on/off/status/toggle) for session-only enablement via runtime tool registration in SessionTools. - Updated docs, changelogs, and contract tests accordingly. --- .github/actions/build-native/action.yml | 18 +- .github/actions/setup-system-deps/action.yml | 27 +- Cargo.lock | 58 +- Cargo.toml | 4 +- crates/pi-natives/Cargo.toml | 15 +- crates/pi-natives/src/desktop.rs | 905 ++----- crates/pi-natives/src/desktop_unsupported.rs | 322 --- crates/pi-natives/src/desktop_x11.rs | 983 +++++++ crates/pi-natives/src/lib.rs | 14 +- crates/vendor/libspa/Cargo.toml | 100 -
