Audit: every "X11 in src/" hit outside src/backend/x11/ and
src/backend/wayland/ is now either:
- a comment mentioning X11 by name, or
- a backend-neutral macro/type alias (WM_STATE_*, CW*, P*, etc.)
whose numeric value happens to match the X11 protocol value.
Zero <X11/...> includes in shared headers/sources.
Zero X11 type uses (XColor/XContext/XEvent/XFontStruct/XGCValues/
XWindowAttributes/XSetWindowAttributes/XErrorEvent etc.).
Zero X11 symbol references in compiled shared object files
(verified: `nm src/*.o | awk '$1=="U"' | grep '^X[A-Z][a-z]'`
returns empty).
Real architectural fixes:
src/backend/backend_types.h — added the missing backend-neutral
constants/types so shared code never names an X11 macro:
- WM_STATE_WITHDRAWN/NORMAL/ICONIC (ICCCM values 0/1/3).
- WContextID (typedef int) — XContext analogue.
- WMColorRGB (XColor-layout-compatible struct).
- CWX..CWStackMode (ConfigureWindow value-mask bits).
- ForgetGravity..StaticGravity (ICCCM win_gravity values).
- PMinSize..PWinGravity (XSizeHints flags) as WNH_* aliases.
- NoSymbol, NoEventMask, ColormapInstalled/Uninstalled.
- BitmapSuccess..BitmapNoMemory.
All guarded by #ifndef so the X11 backend's <X11/X.h> include
overrides them with the real X11 values when present.
src/screen.h — w_visual is now `void *` (was `Visual *`). Added
w_visual_id / w_visual_class so dialog.c's crash panel can read
visual info without dereferencing a Visual struct. tech_draw_font
is also `void *` with companion tech_draw_font_ascent/descent ints
populated by the backend (X11 from XFontStruct->ascent, Wayland
from a hard-coded bitmap-font metric).
src/WindowMaker.h — XContext fields → WContextID, X11 includes
removed, Time → WMNativeTime.
src/dialog.c — wShowCrashingDialogPanel now uses WMOpenScreen +
WMScreenWidth/Height instead of DefaultScreen()/ScreenOfDisplay()/
WidthOfScreen() so it works in either backend.
Dead-code cleanup found while auditing:
src/event.c — handleUnmapNotify and handleEnterNotify both built
an uninitialized `XEvent ev` and ran it through x11_translate_event
on a peeked queue event. The translation always read stack garbage
(the local was never populated). Replaced with the correct flow:
- unmap handler: skip wUnmanageWindow if a Destroy is already
queued, the Destroy handler will run it next iteration.
- enter handler: skip if a Leave for the same window is queued,
no need to inspect mode/detail (was always reading garbage).
Also dropped the now-unused x11_compat.h / x11_event.h includes
from event.c, dock.c, window.c.
src/misc.c — eatExpose's `XEvent event, foo` were never used; the
function delegates to wm_backend->event_flush_type(WME_EXPOSE).
src/wsmap.c — workspace_map_destroy built an XEvent ClientMessage
but never sent it; the actual notify path is switchpanel_send_enter.
Pass the real root_win argument (was passing literal 0) and drop
the dead XEvent.
src/icon.c — set_dockapp_in_icon's `XWindowAttributes attr` and
cycleColor's `XGCValues gcv` were unused.
src/window.c — windowLanguageClick had a function-signature
mismatch with framewin.h's on_click_language (XEvent* vs WMEvent*).
The framewin code passes a WMEvent. Fixed the parameter type and
its single use of event->xbutton.button.
src/moveres.c — already-disabled `#if 0` block in showPosition
that called XDrawLine / XSetForeground on the root window: removed.
Replaced tech_draw_font->ascent/descent dereferences with the new
flat int fields.
src/xutil.h — removed declarations of FormatXError (moved to X11
backend long ago) and Request/GetSelection (never implemented).
Mass renames in shared src/:
IconicState/NormalState/WithdrawnState → WM_STATE_ICONIC/NORMAL/
WITHDRAWN
IconWindowHint/InputHint/StateHint/IconPixmapHint/IconMaskHint/
IconPositionHint/WindowGroupHint/UrgencyHint
→ WMH_*_HINT
XColor (in struct fields and locals) → WMColorRGB
XContext (in screen.context.{...}) → WContextID
XPoint → WMShortPoint
XRectangle → WMShortRect
XFontStruct * → void *
Backends translate at the boundary:
src/backend/x11/x11_backend.c keeps its native XColor/XContext/
XFontStruct internally and casts to the backend-neutral types
at the public-API surface (memcpy works because WMColorRGB has
XColor's exact layout).
src/backend/wayland/wl_backend.c populates the same fields
directly without any X11 indirection.
Verified:
Default build: `Window Maker 0.96.0` runs.
Shared src/ object files: `nm | grep '^X[A-Z][a-z]'` is empty.
All shared X11 macro names (CW*, P*, ICCCM hint flags) are
defined locally in backend_types.h, no X11 dep needed.
Out of scope (separate refactor): wmaker compositor binary itself
still links libX11 because src/backend/x11/* and the XWayland
integration in src/backend/wayland/wl_backend.c need real X11
types. Both are below the vtable, so shared code is unaffected.
The phase-β sed pass renamed every C 'Window' identifier to
WNativeWindow. That correctly updated typedef uses but also rewrote
the string 'Window Maker', UI labels like 'Window Manager', 'Window
Placement', 'Window Title', 'Window List', 'Window System session',
etc., plus a number of comments referring to 'Window' as English.
Fixed all of those. The C type uses (WNativeWindow rootWin, etc.)
remain unchanged — only English-language occurrences are reverted.
Verified that wmaker now reports 'Window Maker 0.96.0' again and
build is clean across WINGs/, src/, WPrefs.app/.
Sed pass restricted to files outside src/backend/x11 and outside
*_x11.c — i.e. all code that should not depend on X11 typedefs.
Window → WNativeWindow (existing typedef in WMEvent.h)
Atom → WMNativeAtom
Pixmap → WMNativePixmap
Cursor → WMNativeCursor
Drawable → WMDrawable (existing typedef)
KeySym → WMNativeKeysym
Colormap → WMNativeColormap
X11 backend files keep using the original Xlib type names because
they make Xlib API calls that take those types. All typedefs are
ultimately 'unsigned long' so values pass through opaquely between
shared code and the backend.
Public WINGs API affected: WMSelectionCallback, WMSelectionProcs,
and a handful of widget signatures that took Atom/Window arguments
now take WMNativeAtom/WNativeWindow. Source-compatible at the
binary level; consumers must rebuild.
Time and XID typedefs left for a follow-up — both are heavily used
in field/variable names that need careful auditing. Display* and
GC stay in W_Screen for now; phase δ moves them into an X11-only
sub-struct.
WINGs API surgery, step 1.
New public header WINGs/WINGs/wnative.h declares WINGs-native types
and constants with no X11 header dependency:
- WMNativePixmap/Atom/Cursor/Keysym/Time/XID/Colormap/Bool typedefs
(all 'unsigned long' — compatible with the existing wire ABI).
- WM_MOD_SHIFT/LOCK/CONTROL/MOD{1..5} modifier mask bits.
- WM_BUTTON{1..5}_MASK pointer button mask bits.
- WM_ANY_MODIFIER/WM_ANY_BUTTON sentinels.
- WM_EVMASK_* event-mask bits (forthcoming patches).
- WM_NOTIFY_* crossing modes/details.
- WM_PROPERTY_* / WM_MAPPING_* / WM_VISIBILITY_* / WM_GRAB_* /
WM_REVERT_TO_* / WM_CURRENT_TIME / WM_NATIVE_NONE.
Numeric values intentionally match X11 layout for binary
compatibility with WMEvent fields (which were defined that way
originally). The architectural property that matters is that NONE
of the symbol *names* below are X11 macros — they belong to WINGs
and are defined without any X11 header.
WMEvent.h, WUtil.h, WINGs.h now #include <WINGs/wnative.h> so every
WINGs consumer picks up the new constants. X11 headers are still
included from the public WINGs headers; phase ε will drop them.
Phase α.1 — first sed pass:
ShiftMask → WM_MOD_SHIFT
ControlMask → WM_MOD_CONTROL
LockMask → WM_MOD_LOCK
Mod{1..5}Mask → WM_MOD_MOD{1..5}
Button{1..5}Mask → WM_BUTTON{1..5}_MASK
AnyModifier → WM_ANY_MODIFIER
AnyButton → WM_ANY_BUTTON
Applied across WINGs/, src/, WPrefs.app/ via sed with word
boundaries. Build verified clean; binary identical in size,
re-linked successfully.
The XDND-on-dock feature was a configure-time toggle (--disable-xdnd)
gating ~25 #ifdef sites across shared src/. This was a pre-Wayland
feature flag, not a backend distinction, but it polluted the policy
layer with build-time conditionals.
Make it unconditional:
configure.ac Remove --disable-xdnd and AM_CONDITIONAL. XDND on
the dock is always built.
src/Makefile.am Move xdnd.c from the if-USE_DOCK_XDND block into
the unconditional wmaker_SOURCES list.
src/dock.h, dock.c, dockedapp.c, appicon.h, appicon.c, event.c,
misc.c, startup.c, dialog.c, screen.h
Strip all #ifdef USE_DOCK_XDND/#endif pairs. In
dockedapp.c the #else branch (rendering an 'XDnD
support was not compiled in' label) is dead and
removed.
Backend routing: the X11 backend continues to drive the XDND protocol
through xdnd.c via the existing xdnd_process_client_message /
xdnd_process_selection / xdnd_make_awareness vtable slots. Wayland's
slots are no-ops (XWayland clients drop into the X11 path naturally
via wl_state.x_display).
src/ is now free of feature-flag guards related to DnD.
* usermenu.c notifyClient: replace XSendEvent KeyPress/KeyRelease
synthesis with two wm_backend->client_send_key calls.
* New vtable slot client_send_key(win, keycode, modifier_mask, press).
X11: synthesize XKeyEvent and XSendEvent.
Wayland: same but on wl_state.x_display (XWayland clients). Native
Wayland clients deferred (would need
zwp_virtual_keyboard_v1).
* misc.c: keysymToString was dead code inside #if 0 — removed.
After this change misc.c and usermenu.c carry zero direct Xlib calls.
Add wm_command/wm_command_n fields to wl_toplevel_view.
wl_icccm_set_command stores a deep copy of argv in the view struct;
wl_icccm_get_command returns a NULL-terminated heap copy (caller frees
each string plus the array via wl_icccm_free_command).
handle_toplevel_destroy frees the stored command on cleanup.
Update getCommandForWindow in misc.c: when dpy is NULL (Wayland path),
call wm_backend->icccm_get_command instead of returning NULL immediately.
This allows fixLeaderProperties and session.c to retrieve the command
string for Wayland-managed windows.

Implement wl_client_get_pid using wl_resource_get_client +
wl_client_get_credentials so the WM can retrieve the OS PID of
Wayland clients. Guard getCommandForWindow in misc.c against NULL
dpy to prevent XGetCommand crash when the real PID path fires.
Guard wWindowChangeWorkspace against NULL frame for frameless
Wayland windows. Log pid= in the wManageWindow-succeeded line;
add Phase 50 pid check to smoke test.
