From d21439d0b8fe53d0dd5aa326cbfc515d3644a157 Mon Sep 17 00:00:00 2001 From: Jim Huang Date: Thu, 4 Jun 2026 19:06:39 +0800 Subject: [PATCH 1/2] Support Motif on the compat stack MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This adds lib{Xmu,Xpm,Xext}-compat shared libraries for the active Motif fork[1] alongside the existing libXt-compat, and rework the Xrm resource cascade, event layer, and font surface so its widgets function. Xrm: matchEntry returns a per-component specificity vector compared with memcmp, replacing the flat-sum scoring that violated Xt precedence; XrmEnumerateDatabase honors loose-bound entries so *background-style resources surface under any prefix; parseLine and entryPatternToString decode and re-encode \n, \t, \r, \\, and octal escapes so XtParseTranslationTable consumers see the byte values their grammars expect. Events and input: convertModifierState maps KMOD_ALT to Mod1Mask and KMOD_NUM to Mod2Mask; XK_Alt_R joins XK_Alt_L on Mod1Mask in XkbKeysymToModifiers and the XGetModifierMapping table. XSetInputFocus drives keyboardFocus instead of warning; XGrabKey / XUngrabKey track passive grabs; XGrabKeyboard / XUngrabKeyboard track a modal grab; the event layer routes key events through grabs before falling back to focus. The implicit setKeyboardFocus calls in XSelectInput and XMapWindow are removed so XSetInputFocus is the sole focus authority. postEvent ClientMessage uses calloc, sets send_event = True, and carries a timestamp in data.l[1] for ICCCM compliance. getEventQueueLength lifts its peek buffer from 25 to 256 so expose and configure bursts during Motif geometry negotiation are not silently truncated. Bounds and threading: parsePositiveInt guards INT_MAX before each XLFD digit multiply; decodeString bounds-checks every \\x, \\u, and trailing-backslash payload; the text-render cache wraps lookup, insert, eviction, and the dependent SDL_RenderCopy under one SDL_mutex so concurrent evictions cannot free a texture mid-draw. XSetRGBColormaps and XGetRGBColormaps replace WARN_UNIMPLEMENTED stubs with the ICCCM 6.4 ten-CARD32 wire format (visualid, killid, colormap, red_max, red_mult, green_max, green_mult, blue_max, blue_mult, base_pixel). XmuLookupStandardColormap uses them to synthesize a 24bpp RGB cube on the root window when the requested visual is not already installed. destroyWindow loses its vestigial WARN_UNIMPLEMENTED that was firing on every Motif demo teardown. The shape extension was previously a probe-only stub; this lands a per-pixel snapshot+composite at every destination-side draw entry point so XCopyArea, XCopyPlane, XDrawRectangle/XFillRectangles, XDrawLine(s), XDrawSegments, XDrawPoint(s), XDrawArc(s)/XFillArc(s), XFillPolygon, XClearArea, XPutImage, and the text renderText path all honor the window's installed shape masks. Shape semantics: split the single shapeMask field into shapeBoundingMask and shapeClipMask with independent offsets, matching X's two slots. The composite intersects them: a pixel is admitted iff every installed mask admits it (pixelInsideShape / ShapeMaskView). XShapeQueryExtents reports each kind separately. XShapeCombineMask's black-pixel visual indicator paints only for ShapeBounding (clip masks don't define the window outline). New tests cover the single-mask, intersection, and combine semantics. Shape integration: ShapeGuard (begin/end pair) consolidates the snapshot+composite wrap across the draw primitives so each entry point gets one declaration and one end call that handles all early returns. applyShapeMaskOverDrawnRect returns Bool so callers can suppress presentDrawableIfVisible / repaintMappedChildrenInRect when the SDL readback or texture upload fails, keeping mask-violating output off the visible surface. captureShapeMaskBaseline pre-clips the request to the window bounds so pathological coordinates can't allocate huge readback surfaces. Overflow hardening: every bbox-arithmetic site now runs in int64 with saturating clampToInt. CoordModePrevious accumulators in XFillPolygon and XDrawLines clamp at INT_MIN/INT_MAX before storing into SDL_Point; unionRect, lineDamageRect, polylineDamageRect, arcDamageRect, and the XDrawRectangle damage+corner math all use int64 with DAMAGE_PAD_CAP on stroke padding. XCopyPlane gained a missing BadGC check on gc and a BadMatch return when a shape mask is installed but the destination readback failed (avoids mixing real prior pixels with synthetic GC background in masked-out positions). Wide-line fallback now LOGs the silent 1-pixel downgrade when strokeLineOnRenderer / rasterStrokePath fails so a regression in the path rasterizer isn't invisible. Supporting infrastructure: libXinerama compat shim covering the Xt/Motif probe surface (XineramaQueryExtension/Version/IsActive, QueryScreens enumerates all dpy->screens with SHRT_MAX clamp). libSDL2-x11compat / libSDL2_ttf-x11compat dlopen wrapper libraries so the Motif demo link line doesn't double-bind real SDL2. Mapping-list mutex with eager init from initScreenWindow on the single-threaded XOpenDisplay path and NULL-tolerant lock/unlock wrappers so a SDL_CreateMutex failure degrades to unsynchronized rather than crashes. Motif build wiring propagates LIBS / iconv / runtime LD_LIBRARY_PATH through every sub-make (config, lib/Xm, lib/Mrm, tools/wml, clients/uil, demos). Scripts and build artifacts: capture-motif-demo-screenshots.sh honors MOTIF_DEMO_SCREENSHOT_RESULT_FILE env override post log_dir resolve; compare-motif-reference.py groups by status-row comparison; sync-upstream-headers.py switched from x.org/individual tarballs to gitlab.freedesktop.org archives with corresponding sha256s; the new motif-demos-check, motif-demos-screenshots, and motif-differential-tests make targets wire up the demo validation pipeline. ASan refuses dlopen() with RTLD_DEEPBIND because deep binding bypasses its symbol interception; the CI sanitize job aborts at the first test binary launch with: You are trying to dlopen ... with RTLD_DEEPBIND flag which is incompatible with sanitizer runtime Detect __SANITIZE_ADDRESS__ / __SANITIZE_THREAD__ at compile time (plus __has_feature() for Clang's address/memory/thread sanitizers) and force RTLD_DEEPBIND to 0 in that case. RTLD_LOCAL was already on both dlopen() sites, so the only thing lost is the belt-and-suspenders protection against the wrapper resolving symbols back into itself. Promote two unresolved review findings to real sync The two annotations from d27706e where the prior pass left only a comment got pushed back as still-unresolved by the PR reviewer. Land actual synchronization for both. src/error.c: guard the per-Display side table with an SDL_mutex, lazily allocated on first use (NULL-tolerant lock/unlock if SDL_CreateMutex fails). Read getLastRequestCode's byte under the lock rather than returning the entry pointer — releaseLastRequestCode can otherwise free the node between our unlock and the caller's deref. src/wrapper/sdl-wrapper.c, src/wrapper/sdl-ttf-wrapper.c: load and store the shared dlopen handle plus every per-wrapper realFunc cache via __atomic_load_n / __atomic_store_n with ACQUIRE/RELEASE ordering. The races were always benign (dlopen ref-counts and dlsym is idempotent so the value written is always the same) but C's memory model still classified the unsynchronized accesses as UB; the atomics let the compiler reason about them as ordinary loads/stores rather than fold the cache check into a single read. include/X11/Xmu/Misc.h: MAXDIMENSION was computed as ((1 << 31) - 1) which shifts into the sign bit of a signed int, which C99 6.5.7p4 leaves undefined. Replace with the equivalent hex literal 0x7FFFFFFF. This header gets pulled in by Xmu consumers; UBSan -fsanitize=shift would flag it at every translation unit that includes it. mk/library.mk: the Darwin link line set the dylib install_name to @rpath/ but did not add an LC_RPATH entry. A consumer linked against libX11-compat that loads sibling compat dylibs (libXt-compat, libXpm-compat, etc.) via the same @rpath relies on the loader having some @rpath registered. Add -Wl,-rpath,@loader_path so the dylib resolves its siblings relative to its own directory without forcing the consumer to bake an absolute rpath in. Verified via otool -l on the rebuilt libX11-compat.so: cmd LC_RPATH path @loader_path --- Makefile | 17 + .../earth-drawing-area-width.patch | 15 + compat/xext-compat.c | 89 ++ compat/xinerama-compat.c | 65 + compat/xmu-compat.c | 662 ++++++++ docs/PORTING.md | 25 + examples/motif/hello.c | 65 + examples/motif/simpleapp.c | 77 + examples/motif/togglebox.c | 83 + examples/x11perf/do_blt.c | 2 +- include/X11/SM/SM.h | 11 + include/X11/Xmu/Atoms.h | 50 + include/X11/Xmu/CharSet.h | 14 + include/X11/Xmu/Converters.h | 117 ++ include/X11/Xmu/Misc.h | 21 + include/X11/Xmu/StdCmap.h | 18 + include/X11/Xmu/SysUtil.h | 12 + include/X11/Xmu/WinUtil.h | 14 + include/X11/Xmu/Xmu.h | 12 + include/X11/bitmaps/gray | 4 + include/X11/extensions/Xinerama.h | 26 + include/X11/extensions/shape.h | 15 + include/libxpm-build/config.h | 30 + mk/common.mk | 30 +- mk/config.mk | 10 +- mk/deps.mk | 21 +- mk/examples.mk | 12 +- mk/library.mk | 11 +- mk/libxpm.mk | 49 + mk/libxt.mk | 29 +- mk/motif.mk | 243 +++ mk/pkgconfig.mk | 58 + mk/sdl-wrapper.mk | 38 + mk/tests.mk | 40 +- mk/xcompat-libs.mk | 47 + scripts/capture-motif-demo-screenshots.sh | 445 ++++++ scripts/compare-motif-reference.py | 408 +++++ scripts/profile-motif-demos.sh | 146 ++ scripts/run-motif-differential-tests.py | 445 ++++++ scripts/sync-upstream-headers.py | 43 +- scripts/validate-motif-demos.sh | 175 +++ src/colors.c | 6 +- src/defaults.c | 21 +- src/display.c | 89 +- src/display.h | 11 +- src/drawing.c | 884 ++++++++++- src/drawing.h | 111 ++ src/error.c | 164 +- src/errors.h | 8 + src/events.c | 957 ++++++++---- src/events.h | 5 + src/extension.c | 11 + src/font.c | 938 +++++++++-- src/font.h | 18 + src/gc.c | 47 +- src/image.c | 10 + src/input-method.c | 455 ++++-- src/input-method.h | 23 +- src/input.c | 208 ++- src/input.h | 15 + src/missing.c | 838 ++++++++-- src/pixmap.c | 8 +- src/pointer.c | 47 +- src/region.c | 219 ++- src/resource-types.h | 3 +- src/window-internal.c | 172 ++- src/window.c | 297 ++-- src/window.h | 15 + src/wrapper/sdl-ttf-wrapper.c | 172 +++ src/wrapper/sdl-wrapper.c | 442 ++++++ src/xrm.c | 1285 ++++++++++++---- src/xshape.c | 487 +++++- tests/api-symbols.txt | 9 + tests/bench-paths.c | 75 + tests/check.c | 1369 ++++++++++++++++- tests/symbol-coverage.c | 9 + tests/test-libxpm-link.c | 42 + tests/test-libxt-resources.c | 140 ++ tests/test-motif-link.c | 297 ++++ tests/test-motif-resources.c | 60 + tests/test-xinerama-link.c | 67 + tests/test-xmu-link.c | 138 ++ 82 files changed, 12455 insertions(+), 1411 deletions(-) create mode 100644 compat/motif-patches/earth-drawing-area-width.patch create mode 100644 compat/xext-compat.c create mode 100644 compat/xinerama-compat.c create mode 100644 compat/xmu-compat.c create mode 100644 examples/motif/hello.c create mode 100644 examples/motif/simpleapp.c create mode 100644 examples/motif/togglebox.c create mode 100644 include/X11/SM/SM.h create mode 100644 include/X11/Xmu/Atoms.h create mode 100644 include/X11/Xmu/CharSet.h create mode 100644 include/X11/Xmu/Converters.h create mode 100644 include/X11/Xmu/Misc.h create mode 100644 include/X11/Xmu/StdCmap.h create mode 100644 include/X11/Xmu/SysUtil.h create mode 100644 include/X11/Xmu/WinUtil.h create mode 100644 include/X11/Xmu/Xmu.h create mode 100644 include/X11/bitmaps/gray create mode 100644 include/X11/extensions/Xinerama.h create mode 100644 include/libxpm-build/config.h create mode 100644 mk/libxpm.mk create mode 100644 mk/motif.mk create mode 100644 mk/pkgconfig.mk create mode 100644 mk/sdl-wrapper.mk create mode 100644 mk/xcompat-libs.mk create mode 100755 scripts/capture-motif-demo-screenshots.sh create mode 100755 scripts/compare-motif-reference.py create mode 100755 scripts/profile-motif-demos.sh create mode 100755 scripts/run-motif-differential-tests.py create mode 100755 scripts/validate-motif-demos.sh create mode 100644 src/wrapper/sdl-ttf-wrapper.c create mode 100644 src/wrapper/sdl-wrapper.c create mode 100644 tests/test-libxpm-link.c create mode 100644 tests/test-libxt-resources.c create mode 100644 tests/test-motif-link.c create mode 100644 tests/test-motif-resources.c create mode 100644 tests/test-xinerama-link.c create mode 100644 tests/test-xmu-link.c diff --git a/Makefile b/Makefile index 9e7c623..a6fe060 100644 --- a/Makefile +++ b/Makefile @@ -1,12 +1,29 @@ .DEFAULT_GOAL := all .DELETE_ON_ERROR: +# Include order matters: +# - toolchain.mk first: CC, PYTHON, PKG_CONFIG, version checks. +# - config.mk needs the toolchain values to probe SDL2/pixman. +# - sources.mk + common.mk: source enumeration + Q/V verbosity and +# reusable helpers (shared_lib_rpath_ldflags, etc.) before any +# fragment that needs them. +# - per-library fragments next;

Topology. Previously lint / build / sanitize ran in parallel and the build job did a release pass plus a make clean + DEBUG_LIBX11_COMPAT rebuild serially. Split debug into its own debug-build job so the release and debug paths run concurrently. Add a motif job that builds the thentenaar/motif libXm and libMrm against the compat stack, builds every Motif demo, and runs scripts/validate-motif-demos.sh under SDL_VIDEODRIVER=dummy. This is the local half of the motif-differential make target; the remote ssh comparison half needs a separate physical host and isn't reproducible in a stock GitHub runner. Caching. Three layers, all keyed so cache content can never substitute for differently-flagged content from another job: * upstream-src (shared across build / debug-build / sanitize / motif) caches the deterministic outputs of sync-upstream-headers.py: the tarball download cache, extracted X11 headers, and extracted upstream .c source slices. Excludes build/upstream/**/*.o and *.d so CFLAGS-sensitive objects from $(OUT)/upstream/src/%.o rules don't cross-contaminate release vs debug vs sanitizer builds. Also excludes build/upstream/motif-src which has its own cache. * motif-src (motif job only) caches the Motif git clone and the autoreconf output. Exact-match key on mk/motif.mk + patches with no restore-keys fallback: the .source-stamp / .autogen-stamp files inside motif-src don't depend on those inputs in the makefile, so a stale prefix restore would let make skip a fresh clone+patch+ autoreconf after inputs changed. * ccache per-job (build / debug-build / sanitize / motif) with distinct keys so the sanitizer-instrumented objects, debug-flag objects, and release objects each get their own pool. CC=ccache clang is exported via $GITHUB_ENV; mk/toolchain.mk's "ifeq ($(origin CC),default)" check correctly treats the env-supplied value as authoritative. Concurrency. cancel-in-progress fires only when github.ref is not main, so PR pushes still cancel stale runs but main commits get a complete CI record and cache-save pass. Motif autotools. Ubuntu's bison package ships /usr/bin/bison but no /usr/bin/yacc. mk/motif.mk defaults MOTIF_YACC to yacc on Linux; set MOTIF_YACC=bison -y at job env so the Mrm parser generation works without adding byacc as a build dep. The configure script bakes the resolved YACC value into the generated Makefile so the recursive submakes pick it up. --- .github/workflows/ci.yml | 276 ++++++++++++++++++++++++++++++-- scripts/validate-motif-demos.sh | 24 +++ 2 files changed, 286 insertions(+), 14 deletions(-) diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index cbee50e..397c2db 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -1,7 +1,14 @@ -# Build libx11-compat, run the regression suite, and gate on lint / -# sanitizer findings.
