Build system (5 gaps hardened): - COOKBOOK_OFFLINE defaults to true (fork-mode) - normalize_patch handles diff -ruN format - New 'repo validate-patches' command (25/25 relibc patches) - 14 patched Qt/Wayland/display recipes added to protected list - relibc archive regenerated with current patch chain Boot fixes (fixable): - Full ISO EFI partition: 16 MiB → 1 MiB (matches mini, BIOS hardcoded 2 MiB offset) - D-Bus system bus: absolute /usr/bin/dbus-daemon path (was skipped) - redbear-sessiond: absolute /usr/bin/redbear-sessiond path (was skipped) - daemon framework: silenced spurious INIT_NOTIFY warnings for oneshot_async services (P0-daemon-silence-init-notify.patch) - udev-shim: demoted INIT_NOTIFY warning to INFO (expected for oneshot_async) - relibc: comprehensive named semaphores (sem_open/close/unlink) replacing upstream todo!() stubs - greeterd: Wayland socket timeout 15s → 30s (compositor DRM wait) - greeter-ui: built and linked (header guard unification, sem_compat stubs removed) - mc: un-ignored in both configs, fixed glib/libiconv/pcre2 transitive deps - greeter config: removed stale keymapd dependency from display/greeter services - prefix toolchain: relibc headers synced, _RELIBC_STDLIB_H guard unified Unfixable (diagnosed, upstream): - i2c-hidd: abort on no-I2C-hardware (QEMU) — process::exit → relibc abort - kded6/greeter-ui: page fault 0x8 — Qt library null deref - Thread panics fd != -1 — Rust std library on Redox - DHCP timeout / eth0 MAC — QEMU user-mode networking - hwrngd/thermald — no hardware RNG/thermal in VM - live preload allocation — BIOS memory fragmentation, continues on demand

Qt 5.12.4 is a bug-fix release. It maintains both forward and backward
|
|
compatibility (source and binary) with Qt 5.12.0 through 5.12.3.
|
|
|
|
For more details, refer to the online documentation included in this
|
|
distribution. The documentation is also available online:
|
|
|
|
https://doc.qt.io/qt-5/index.html
|
|
|
|
The Qt version 5.12 series is binary compatible with the 5.11.x series.
|
|
Applications compiled for 5.11 will continue to run with 5.12.

- X11 / XCB:
|
|
* [QTBUG-45375] QTabletEvent coordinates now come from AbsX/AbsY
|
|
valuators in the X11 event, in more precise 32.32 fixed-point format,
|
|
scaled to fit the virtual desktop. It's possible to revert to using
|
|
the legacy 16.16-format event_x/event_y coordinates as in previous
|
|
releases by setting the QT_XCB_TABLET_LEGACY_COORDINATES environment
|
|
variable.

|
- Global:
|
|
* [QTBUG-72073] Added the QT_NO_FLOAT16_OPERATORS macro in order to work
|
|
around a Microsoft <= VS2017 compiler bug that is exposed when using
|
|
std::bitset along with any Qt header that includes <qfloat16.h>.
|
|
|
|
- QDeadlineTimer:
|
|
* [QTBUG-69750] Fixed integer overflows leading to immediate timeouts.
|
|
|
|
- QFile:
|
|
* Made QFile::copy() issue a filesystem-synchronization system call,
|
|
which would make it less likely to result in incomplete or corrupt
|
|
files if the system reboots or uncleanly shuts down soon after the
|
|
function returns. New code is advised to use QSaveFile instead, which
|
|
also allows to display a progress report while copying.
|
|
|
|
- QFileInfo:
|
|
* [QTBUG-63970][QTBUG-30401][QTBUG-20791] Fixed resolving of symbolic
|
|
links to UNC shares on NTFS file systems.
|
|
|
|
- QMetaObject:
|
|
* Non-copyable lambdas can now be used with invokeMethod(). For
|
|
consistency reasons, the functor object is now always moved.

macOS. They can be forced off by setting

AA_DontShowShortcutsInContextMenus to true.
