Phase θ — wrlib's X11 image-conversion path (RConvertImage,
RPutXImage, the X11 RCreateContext, libXpm-based RLoadXPM) is now
opt-out via --disable-x11-wraster, mirroring the WINGs phase η work.
Result: with --disable-x11-backend --disable-x11-wraster the WINGs
runtime libraries have ZERO libX11 transitive deps:
$ ldd WINGs/.libs/libWINGs.so | grep X11
(empty)
$ ldd wrlib/.libs/libwraster.so | grep X11
(empty)
That was the last libX11 transitive dep coming through WINGs — the
goal of the API surgery is now achieved at the library level.
configure.ac:
- New --enable-x11-wraster (default = same as --enable-x11-backend),
AM_CONDITIONAL([USE_X11_WRASTER]), AC_DEFINE([USE_X11_WRASTER]).
Forcing --disable-x11-wraster while --enable-x11-backend is rejected
(X11 backend depends on the X11 conversion path).
- WRASTER_GFXLIBS_NO_XPM: GFXLIBS with -lXpm filtered (libXpm pulls
libX11; load_xpm_normalized.c is the X11-free XPM loader used in
the disabled-X11 build).
- WINGS_PANGO_LIBS_NO_XFT: PANGO_LIBS with -lpangoxft-* and -lXft
filtered (PangoXft depends on libXft -> libX11; pangoft2 path is
the X11-free Pango variant).
wrlib/Makefile.am:
- Split source list: shared / X11-only / Wayland-only.
- X11 sources (context.c, convert.c, convert_x11.c, xpixmap.c,
xutil.c, load_xpm.c) only built when USE_X11_WRASTER.
- New context_wl.c (always built) — Wayland-mode RCreateContextWayland
extracted from context.c.
- New wstubs_no_x11.c (only built when !USE_X11_WRASTER) — empty
stubs for the public wraster API symbols normally exported from
the X11 path (RCreateContext, RDestroyContext, RConvertImage,
RConvertImageMask, RGetClosestXColor, RCreateImageFromDrawable,
RCreateImageFromXImage, RCreateXImage, RGetXImage, RDestroyXImage,
RPutXImage, RGetImageFromXPMData, RLoadXPM).
- @XLIBS@/@LIBXMU@ only added to libwraster_la_LIBADD when
USE_X11_WRASTER; load_xpm.c only built when (USE_XPM and
USE_X11_WRASTER).
- Added --filter USE_X11_WRASTER to the wraster.h generation rule
so the @!USE_X11_WRASTER@ lines (forcing WRASTER_NO_XLIB) are
retained when X11 is disabled.
wrlib/wraster.h.in:
- When USE_X11_WRASTER is undefined at config time, force
WRASTER_NO_XLIB so consumers see only forward-decl'd opaque types
(Display/Visual/XImage/etc.) and never <X11/Xlib.h>.
- Added True/False/None defines to the WRASTER_NO_XLIB block (raster.c
uses them; previously got via Xlib.h).
wrlib/context.c — RCreateContextWayland moved out to context_wl.c.
wrlib/wstubs_no_x11.c — new (157 lines).
wrlib/context_wl.c — new (extracted Wayland branch).
WINGs/Makefile.am:
- libWINGs_la_LIBADD now uses WINGS_PANGO_LIBS, which is @PANGO_LIBS@
when X11 backend enabled, @WINGS_PANGO_LIBS_NO_XFT@ otherwise.
WINGs/widgets.c — WMCreateScreen + WMCreateSimpleApplicationScreen
moved to widgets_x11.c (they use DefaultScreen() and RCreateContext()
which are X11-only). Stubs added in WINGs/wstubs_no_x11.c.
WINGs shared rootWin assignment now reads context->drawable instead
of calling X11 RootWindow() macro directly.
WINGs/WINGs/wnative.h — added X11-numeric constants used by shared
WINGs widget code:
- Button1..Button5 (X.h pointer-button numbers)
- KeyPress..LASTEvent (X.h event-type constants)
- CWBackPixmap..CWCursor (X.h CreateWindow/ChangeWindowAttributes
mask bits)
- WMShortRect (XRectangle layout-compatible struct)
All guarded by #ifndef so X11 headers can override on the X11 build.
WINGs/configuration.c — dropped unused <X11/Xlocale.h> include.
WINGs/wruler.c, wtabview.c, wtext.c — replaced raw XPoint/XRectangle
with WMShortPoint/WMShortRect; replaced lone XSetWindowAttributes
shim with direct view->attribs.cursor access.
src/WindowMaker.h — explicitly include <X11/Xlib.h>, <X11/Xutil.h>,
<X11/Xresource.h>, <X11/Xatom.h>. The wmaker compositor uses these
extensively in its public headers; previously got them transitively
via WINGs.h. After the WINGs surgery WINGs.h no longer pulls Xlib,
so the compositor must include them itself.
Verified:
Default build (--enable-x11-backend, --enable-x11-wraster):
Window Maker 0.96.0 boots, all features intact.
Pure-Wayland build (--disable-x11-backend --disable-x11-wraster):
libwraster.so / libWINGs.so build cleanly, no libX11 in ldd.
(wmaker compositor binary still has X11 deps from src/* code;
out of scope for this commit — that's a compositor-level
refactor.)
Major architectural milestone: WINGs Wayland-only files now have ZERO
transitive X11 header dependency at the preprocessor level (verified by
gcc -E grep: 0 mentions of X11/Xlib.h after preprocessing).
Changes:
1. WUtil.h, WINGs.h: stop including <X11/Xlib.h>. wnative.h provides
forward declarations for Display, GC, XftDraw, XftFont; opaque
pointer-only typedefs that don't conflict with Xlib.h's actual
definitions when the X11 backend later includes it.
2. WINGsP.h.in: stop including <X11/Xlib.h>, <X11/Xutil.h>. Drop or
re-route every X11-typed prototype:
- W_HandleDNDClientMessage / W_DragSourceStateHandler /
W_DragDestinationStoreEnterMsgInfo / etc.
→ moved to new private header WINGs/WINGsX11.h
- W_HandleSelectionEvent → moved
- W_LookupString / W_KeycodeToKeysym → moved
- W_DndState typedef → moved (renamed to W_X11DndState)
- XClientMessageEvent / XEvent / XKeyPressedEvent in prototypes
→ use void * in shared protos, cast in WINGsX11.h
3. W_View struct: replaces XSetWindowAttributes by-value field with a
small backend-neutral 'attribs' struct holding only the fields
wmaker/WPrefs actually use (background_pixmap, background_pixel,
border_pixel, colormap, cursor, override_redirect, save_under,
event_mask, do_not_propagate_mask). The X11 view backend
translates to XSetWindowAttributes when calling XCreateWindow.
XIC xic field replaced with void *xic.
4. W_Color struct: replaces XColor by-value with a same-layout
anonymous struct (pixel/red/green/blue/flags/pad). X11 backend
uses memcpy to populate from XColor.
5. WINGs/WINGsX11.h (new): private header for X11 backend. Includes
<X11/Xlib.h>, declares X11-typed internal prototypes used by drag*,
selection, IME, x11_backend, KeyboardShortcuts. Required by every
*_x11.c file plus a handful of cross-component callers
(KeyboardShortcuts.c, MouseSettings.c, xmodifier.c, wmiv.c,
x11_backend.c).
6. wraster.h.in: gain a WRASTER_NO_XLIB compile-time switch. When
defined the header skips <X11/Xlib.h> and provides forward decls
for Display/Visual/XImage/GC/XftFont/etc. All Wayland-only WINGs
files (wclient_wl.c, w*_wl.c) define WRASTER_NO_XLIB on line 1.
7. wfont.c: adds W_ParseXLFDToFcPattern (a hand-written XLFD parser)
replacing XftXlfdParse. Removes <X11/Xft/Xft.h> include from the
shared font dispatcher (and from wfontpanel.c too).
Verification:
$ for f in WINGs/.libs/{*_wl.o,wclient_wl.o}; do
nm $f | awk '$1=="U"{print $2}' | grep -cE '^X[A-Z][a-z]'
done
0 for every Wayland file
$ for f in WINGs/.libs/*.o; do
case $f in *_x11.o|*_wl.o|wclient_wl.o) continue;; esac
c=$(nm $f | awk '$1=="U"{print $2}' | grep -cE '^X[A-Z][a-z]')
[ $c -gt 0 ] && echo "$c $f"
done
(empty — no shared file leaks an X11 symbol either)
$ gcc -E ... wclient_wl.c | grep -c X11/Xlib.h
0 (no transitive Xlib include)
The library still pulls libX11 through the *_x11.c files when those are
linked in. A future configure flag --disable-x11-backend will exclude
*_x11.c entirely; at that point libWINGs will be a pure-Wayland library
with zero libX11 dependency.
RConvertImage and RConvertImageMask now dispatch through function
pointers on RContext, set during context creation:
- RCreateContext sets x11_convert_image/x11_convert_image_mask
- RCreateContextWayland sets wl_convert_image/wl_convert_image_mask
The Wayland backend creates pixman_image_t from RImage RGBA data
instead of returning NULL pixmaps, fixing the SIGSEGV in the exit
dialog when compositing the application icon.
X11 code moved to convert_x11.c, Wayland code in convert_wl.c.
No dpy guards in the middle layer.
wraster.h is generated from wraster.h.in — the declaration was only
in the generated file, not the template. Also includes the Wayland
no-op for RConvertImage/RConvertImageMask (context->dpy == NULL).
