feat: Cross-platform automation support for Linux and macOS#5

Replace fragile title-based matching with robust PID correlation: - Get X11 window PID from _NET_WM_PID property - Match to AT-SPI2 app via GetConnectionUnixProcessID D-Bus call - Add zbus dependency for D-Bus proxy access - Add get_window_info_by_id helper for window lookups - Reduce default tree traversal depth to 10 for performance This approach works reliably for Firefox and KDE apps, unlike title matching which failed for apps that don't implement the Accessible interface on window children.

The previous xcap 0.0.13 pulled in moxcms 0.7.11 which requires Rust edition 2024 (unstable). This caused CI builds to fail on rust:1.84 with "feature `edition2024` is required" error.

On macOS builds, the top-level ops for window listing/tree/patterns always return Platform not supported because these functions are hard‑wired to platform_not_supported() and never call the newly implemented macOS automation modules. As a result, CLI commands like list‑windows, dump‑tree, find‑elements, etc. will fail on macOS despite the commit adding those features. This is user‑visible breakage specifically on macOS; these ops should delegate to automation::macos::{window, accessibility, ...} similar to the Linux/Windows ops wiring.

The AT‑SPI2 lookup matches only by PID and then returns the first window child for that process. For multi‑window apps (e.g., browsers, editors, IDEs), this can return the wrong window and cause dump_tree/find_elements/invoke_pattern to operate on an unrelated window, even though the caller passed a specific X11 window ID. The bug appears whenever multiple windows share the same PID; you’ll need to disambiguate (e.g., match AT‑SPI2 window by title/role using get_window_title or correlate window IDs) rather than always picking app_children[0].

Unsafe pointer cast without validation. The code casts property.value.as_ptr() to *const u32 and creates a slice without verifying alignment. While the comment mentions X11 guarantees 4-byte alignment for format=32, this should be validated at runtime or use safe alternatives like bytemuck for better safety guarantees.

Truncation function doesn't handle multi-byte UTF-8 characters correctly. The function calls &s[..boundary] after finding character boundaries, but the boundary calculation uses char_indices().take_while(|(i, _)| *i <= target) which may not find the correct boundary. The implementation should verify the boundary is at a valid char boundary or use floor_char_boundary API if available.

Global allow directives disable important warnings for the entire crate. Using #![allow(dead_code)] and #![allow(unused_imports)] at the crate level suppresses warnings that could indicate real issues. These should be removed or replaced with more targeted allows on specific items that genuinely need them.

Code ReviewI found 8 issues in this PR that need to be addressed: 1. Broken Windows compilation - removed imports still referencedFile: src/executor/engine.rs:2-3 The imports capture_screenshot and ScreenshotMethod are no longer exported from crate::automation::windows since this PR removes pub mod screenshot and pub use screenshot::* from src/automation/windows/mod.rs. This will cause a compilation failure on Windows. The screenshot functionality appears to have been moved/refactored, but these imports were not updated. 2. macOS window operations return not supported despite implementations existingFile: src/ops/macos_ops.rs:35-43 The list_windows and get_window_by_hwnd functions unconditionally return platform_not_supported() errors. However, working implementations exist in src/automation/macos/window.rs (list_windows and get_window_info_by_id). These ops functions should delegate to the automation layer implementations, similar to how click, type_text, etc. delegate to macos::input::* functions. As written, macOS window listing will always fail even though the underlying code exists. 3. Test references non-existent function nameFile: tests/cross_platform_test.rs:176 The test calls desktop_cli::automation::macos::permissions::check_permissions, but the actual function in src/automation/macos/permissions.rs:7 is named check_accessibility_permission. This will fail to compile on macOS. 4. Windows get_summary has semantic parameter mismatchFile: src/ops/windows_ops.rs:468-476 The trait implementation has two issues:
This will produce incorrect results for any caller. 5. Linux invoke_pattern invokes actions on root window instead of found elementFile: src/automation/linux/atspi.rs:401-440 The function finds an element matching selector and assigns it to _element (line 401), but then builds the ActionProxy and ValueProxy using accessible.connection(), accessible.destination(), and accessible.path() (lines 405-410, 426-431) -- all referring to the root window accessible, not the found element. This means every invoke_pattern call will perform the action on the root window element regardless of what selector was provided. The found elements D-Bus path should be used instead. 6. macOS check_accessibility_permission uses dangling pointerFile: src/automation/macos/permissions.rs:15 The line creates a temporary CFString, calls as_CFTypeRef(), and the temporary is immediately dropped. The resulting key is a dangling pointer to freed memory. This pointer is then used in CFDictionaryCreate (lines 18-25), leading to undefined behavior. 7. macOS invoke_element casts arbitrary hex strings to raw pointersFile: src/automation/macos/accessibility.rs:348-373 The invoke_element function (and similarly get_value_pattern) parses an element_id string as a hex number and casts it directly to AXUIElementRef (raw pointer) with no validation (lines 351-358). Element IDs come from dump_tree, which formats pointer addresses as hex strings. However, theres no validation that the pointer is still valid. Dereferencing these stale pointers is undefined behavior and could lead to crashes or memory corruption. 8. macOS ops layer returns platform not supported for operations with working implementationsFile: src/ops/macos_ops.rs:50-90 The following macOS ops functions return platform_not_supported() despite having working implementations in the automation layer:
These ops functions should delegate to macos::accessibility::* implementations, similar to how the Linux ops correctly delegate to linux::atspi::*. |

Code Review
This is an impressive and substantial pull request that adds cross-platform support for Linux and macOS. The architectural approach using a DesktopPlatform trait with compile-time dispatch is solid and well-executed. The addition of comprehensive documentation, a Docker-based CI environment for Linux, and property-based tests demonstrates a high level of quality and forethought. My review focuses on a few areas for improvement, primarily around wiring up the new macOS implementation and improving the robustness of the CI scripts. Overall, this is excellent work.

It appears that many of the functions in this file, such as list_windows, dump_tree, and find_elements, are stubbed to return platform_not_supported(). However, the underlying implementations seem to exist in the src/automation/macos/ directory. These ops functions should be updated to call their corresponding implementation in the automation layer, similar to how linux_ops.rs is structured. Without this, the macOS support will not be functional.

Using a fixed sleep can lead to race conditions and flaky tests in CI, especially on slower runners. It's more robust to poll until the AT-SPI D-Bus service is actually available. Consider replacing the sleep 1 with a loop that checks for the service readiness.
# Wait for the AT-SPI bus to be ready
timeout 10s bash -c 'until dbus-send --session --print-reply --dest=org.a11y.Bus /org/a11y/bus org.freedesktop.DBus.Peer.Ping > /dev/null 2>&1; do sleep 0.1; done'

Similar to the main Dockerfile, this fixed sleep can introduce flakiness. It would be more reliable to poll for the AT-SPI service to ensure it's ready before proceeding with tutorial generation.

These crate-level allow attributes for dead_code and unused_imports can hide useful compiler warnings. While helpful during development, they should be removed before merging to ensure the codebase is clean and no unused code is left behind.

Similar to lib.rs, these crate-level allow attributes should be removed before merging. This will help maintain code quality by ensuring that all dead code and unused imports are addressed.
