#
# Wayland backend smoke test for Window Maker.
# Uses the wlroots headless compositor (no display hardware needed).
#
# Currently verifies:
#   1. wmaker was built with Wayland backend support (symbol present)
#   2. wmaker links against wlroots
#   3. wmaker starts with WMAKER_USE_WAYLAND=1 and reaches the event loop
#      without crashing (verified by sending SIGTERM and checking exit status)
#   4. (Phase 34) A Wayland compositor socket is created in XDG_RUNTIME_DIR
#   5. (Phase 35) Core Wayland globals advertised (wl_compositor, wl_seat,
#      xdg_wm_base) — verified via weston-info if available
#   6. (Phase 36) wl_shm and wl_output advertised; a real SHM client
#      (weston-simple-shm) can connect without crashing the compositor
#   7. (Phase 37) Frame callbacks fire; weston-simple-shm runs its render
#      loop (stays alive for 3 s, compositor still alive afterwards)
#   8. (Phase 38) Per-toplevel view lifecycle: compositor logs "toplevel
#      mapped" when weston-simple-shm creates its XDG toplevel surface
#   9. (Phase 39) wManageWindow called for mapped XDG toplevel: compositor
#      logs "wManageWindow succeeded" for the synthetic surface ID
#  10. (Phase 40) wUnmanageWindow called when client disconnects: compositor
#      logs "toplevel unmapped" and exits cleanly after cleanup
#  11. (Phase 41) prop_get_wm_class returns XDG app_id: "wManageWindow
#      succeeded" log includes class=org.freedesktop.weston.simple-shm
#  12. (Phase 42) window_get_client_attrs returns WCLIENT_VIEWABLE + geometry:
#      "wManageWindow succeeded" log includes geo= with non-zero size
#  13. (Phase 43) focus_set delivers keyboard focus via wlr_seat: compositor
#      logs "focus_set id=" after wManageWindow succeeds
#  14. (Phase 44) client_synth_configure/window_resize send XDG configure
#      events so clients receive WM-initiated size changes (no external check)
#  15. (Phase 45) pointer_query returns 1 so wSetFocusTo fires from
#      wManageWindow; wWindowFocus/Unfocus guarded on frame!=NULL
#  16. (Phase 50) client_get_pid returns real PID via wl_client_get_credentials;
#      logged as pid= in wManageWindow succeeded line
#  17. (Phase 51) two simultaneous clients both managed and unmanaged cleanly;
#      compositor survives multi-client scenario
#  18. (Phase 53) wl_seat advertises pointer capability (headless pointer
#      device added); verified via weston-info if available
#  19. (Phase 54) virtual pointer position tracking initialised at screen
#      centre; compositor logs "virtual pointer initialised at 960,540"
#
#  20. (Phase 62) wl_screen_create_internals sets no_focus_win=WNATIVE_NONE;
#      wl_focus_set(WNATIVE_NONE) calls wlr_seat_keyboard_clear_focus and logs
#      "focus_clear" when the last managed window unmaps.
#  21. (Phase 63) PropGetProtocols sets DELETE_WINDOW=1 for Wayland windows;
#      wClientSendProtocol dispatches client_close so MC_CLOSE is enabled and
#      polite close works; verified by wManageWindow logging kill_close=0.
#  22. (Phase 64) zxdg_decoration_manager_v1 advertised in global registry;
#      compositor logs "xdg-decoration-manager created"; new toplevels receive
#      CLIENT_SIDE mode ("decoration mode=client_side" logged).
#  23. (Phase 65) prop_get_transient_for returns parent XDG surface ID for
#      dialog windows (build-only check — weston-simple-shm has no transients).
#  24. (Phase 66) XDG popup initial configure scheduled so context menus and
#      autocomplete dropdowns can commit first buffer without stalling
#      (build-only check — weston-simple-shm creates no popups).
#  25. (Phase 67) WWindow.workspace added; wWorkspaceForceChange uses it as
#      fallback when frame==NULL so workspace switching is safe in Wayland
#      (build-only check — workspace switch requires keyboard shortcuts).
#  26. (Phase 68) placement.c guards: calcSumOfCoveredAreas/window_overlaps
#      skip frameless (Wayland) windows safely; frame->workspace accesses
#      in icon-placement helpers use wwin->workspace fallback.
#  27. (Phase 69) WIN_WORKSPACE(w) macro added; frame->workspace reads in
#      wWindowFocusPrev/Next, wWindowObscuresWindow, wWindowSaveState,
#      session.c, and switchmenu.c replaced with the macro.
#  28. (Phase 70) WIN_WORKSPACE macro applied to remaining frame->workspace
#      reads in actions.c, cycling.c, event.c, moveres.c, placement.c,
#      switchpanel.c, wmspec.c, workspace.c; write sites keep direct access.
#  29. (Phase 71) Early-return guards added to wShadeWindow, wUnshadeWindow,
#      wMaximizeWindow, wUnmaximizeWindow, wFullscreenWindow, wIconifyWindow,
#      wDeiconifyWindow so that Wayland windows (frame==NULL) do not crash
#      when these actions are triggered (build-only check).
#  30. (Phase 72) Early-return guards in keyboard shortcut handlers
#      in event.c (WKBD_KEEP_ON_TOP, WKBD_KEEP_AT_BOTTOM, WKBD_RAISE,
#      WKBD_LOWER, WKBD_RAISELOWER, WKBD_WINDOWMENU, WKBD_XKB_TOGGLE) and
#      to wKeyboardMoveResizeWindow, wMouseMoveWindow, wMouseResizeWindow in
#      moveres.c so Wayland windows do not crash on frame->core access
#      (build-only check).
#  31. (Phase 73) Frame NULL guards in wmspec.c (wNETFrameExtents) and
#      winmenu.c (OpenWindowMenu, execWindowOptionCommand, updateOptionsMenu)
#      so Wayland windows do not crash on frame->core stacking access
#      (build-only check).
#  32. (Phase 74) Frame NULL guards in window.c: wWindowConfigure dispatches
#      client_synth_configure for Wayland windows; wWindowSingleFocus and
#      wWindowSaveState use client geometry fallback when frame is NULL
#      (build-only check).
#  33. (Phase 75) Frame NULL guards in cycling.c: raiseWindow skips stacking
#      for Wayland windows; change_focus_and_raise guards fullscreen stacking
#      restore (build-only check).
#  34. (Phase 76) switchpanel.c: Alt-Tab panel title falls back to
#      wwin->wm_class when frame is NULL so Wayland windows appear in the
#      switcher without crashing (build-only check).
#  35. (Phase 77) XKB keymap set on headless keyboard so wl_keysym_to_keycode
#      produces real keycodes; modifier masks (Alt=Mod1Mask, Super=Mod4Mask)
#      set via wSetModifierMasks so wKeyBindings are populated correctly;
#      XKeysymToKeycode(dpy,...) replaced by vtable in defaults.c/rootmenu.c/
#      usermenu.c so keyboard shortcuts are correctly configured in Wayland mode.
#      Verified by "XKB keymap set on headless keyboard" log.
#  36. (Phase 78) wWaylandKeyPress() added to event.c: scans wKeyBindings
#      and dispatches WM shortcuts (miniaturize, hide, maximize, raise/lower,
#      close, focus, workspace switch) without needing an XEvent.
#      Keyboard key+modifiers listeners wired in wl_backend so key events
#      from the headless keyboard are dispatched through the WM shortcut
#      handler before being forwarded to focused clients.
#      Verified by "keyboard key+modifiers listeners wired" log.
#  37. (Phase 13) Pointer focus delivered: after wManageWindow succeeds the
#      virtual pointer is warped to the window centre; wl_update_pointer_focus
#      calls wlr_seat_pointer_notify_enter/motion/frame so the Wayland client
#      receives wl_pointer.enter events.  wl_client_synth_configure now records
#      the WM-assigned position (v->x/v->y) so view_surface_at() returns the
#      correct surface.  Verified by "pointer focus entered surface" log.
#  40. (Phase 18) wlr_scene created; nested Wayland compositor mode when
#      WMAKER_WAYLAND_NESTED=1 (uses wlr_wl_backend + wlr_multi_backend),
#      headless mode otherwise.  Scene nodes added for each XDG/XWayland
#      surface so client content is composited into the output frame.
#      Phase 18 fix: scene and output_layout created before wlr_backend_start
#      so handle_backend_new_output finds a valid scene when it fires.
#      Verified by "scene graph created" + "scene output created" +
#      "headless compositor mode" logs.
#  39. (Path 1) XWayland eager start + Display* bridge: wlr_xwayland_create()
#      called with lazy=false; ready signal fires when Xwayland socket accepts
#      connections; handle_xwayland_ready() opens Display* via XOpenDisplay().
#      wl_display_open() pumps event loop until Display* set (up to 10 s),
#      then returns it to main.c so WindowMaker's X11 UI renders through Xwayland.
#      Compositor logs "XWayland starting on" + "XWayland Display* ready" or
#      "XWayland ready timeout" (headless/no-Xwayland envs).
#      Verified by "XWayland starting on" log.
#  43. (Phase 24) Click-to-focus: on WLR_BUTTON_PRESSED, view_surface_at()
#      finds the view under the pointer; wSetFocusTo delivers WM keyboard
#      focus and wlr_scene_node_raise_to_top raises it in Z-order.
#      seat->events.request_set_cursor wired: clients can set custom cursor
#      images (I-beam, hand, etc.) via wl_pointer.set_cursor.
#      (Build-only check — no multi-window focus test here.)
#  44. (Phase 25) Clipboard: seat->events.request_set_selection wired so
#      Ctrl-C / copy operations propagate to the seat selection and become
#      available for paste in other clients via wl_data_device.
#      Verified by "clipboard selection wired" log line.
#  42. (Phase 23) Cursor image rendering: wlr_cursor + wlr_xcursor_manager
#      created and attached to output_layout; xcursor theme (default, 24px)
#      loaded at scale 1.0; "left_ptr" image set on each output after it joins
#      the layout.  In nested Wayland mode this sends wl_pointer.set_cursor to
#      the host compositor making the cursor visible.  Grab begin/end switch to
#      "fleur" / edge-resize cursors and restore "left_ptr" on release.
#      wlr_cursor_warp called from all motion handlers and pointer_warp_to/
#      warp_to so the hardware cursor tracks the virtual pointer position.
#      Verified by "cursor created, xcursor theme loaded" +
#      "cursor image set to 'left_ptr'" log lines.
#  41. (Phase 22) Interactive move/resize grab: request_move and request_resize
#      handlers now start a compositor-side grab that tracks pointer motion
#      and repositions/resizes the window in the scene graph.  Button release
#      ends the grab.  Build-only check (no client sends request_move here).
#  48. (Phase 29) Scroll wheel: pointer->events.axis wired for both headless
#      and real nested pointer devices → wlr_seat_pointer_notify_axis; axis
#      events dropped during compositor grab.  Focus-follows-pointer: when
#      wPreferences.focus_mode==WKF_SLOPPY, wSetFocusTo called on pointer enter.
#  49. (Phase 29) wp_viewporter created (mpv, Chromium, Firefox video scaling).
#  50. (Phase 30) zwp_relative_pointer_manager_v1 + zwp_pointer_constraints_v1
#      created; new_constraint activates immediately so game pointer-lock works.
#  51. (Phase 31) zwp_keyboard_shortcuts_inhibit_manager_v1 created; new
#      inhibitor activated immediately so fullscreen apps capture all keys.
#  45. (Phase 26) wl_subcompositor already advertised by wlr_compositor_create
#      (embedded in wlr_compositor struct); verified via weston-info.
#      zwp_primary_selection_device_manager_v1 created; seat
#      request_set_primary_selection wired → wlr_seat_set_primary_selection
#      so middle-click paste propagates between clients.
#  46. (Phase 27) zxdg_output_manager_v1 created from output_layout so panels
#      and HiDPI apps can query logical output geometry.
#  47. (Phase 28) zwp_idle_inhibit_manager_v1 created; new_inhibitor wired so
#      video players and games can suppress screen blanking.
#  38. (Phase 11) noclip/nodock set in wl_screen_create_internals: wDockCreate
#      requires X11 rendering resources unavailable in Wayland mode; disabling
#      the dock/clip prevents crashes when wWorkspaceNew is called to create
#      additional workspaces.  App icon creation path (wApplicationCreate →
#      create_appicon_for_application → wIconUpdate/wIconPaint) guarded with
#      !dpy early returns so the full manage/unmanage lifecycle works without
#      X11 rendering.  Verified by "dock/clip disabled" log message.
#  52. (Phase 29+) signalfd-based SIGTERM handling: wl_event_loop_run()
#      creates a signalfd for SIGTERM/SIGINT/SIGHUP and registers it in the
#      wlroots event loop via wl_event_loop_add_fd.  This ensures SIGTERM is
#      handled synchronously from within the dispatch loop (not from an async
#      signal handler), fixing SIGTERM non-response in interactive nested-Sway
#      mode where the SA_RESTART + epoll ordering could race.  The traditional
#      pipe-based wl_event_loop_terminate() is retained as a secondary
#      mechanism.  Verified by "signalfd installed for SIGTERM" log message.
#
# This test grows as wl_backend vtable slots are implemented.
#
