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

This is a collection of functions and classes helpful for diagnosing bugs
|
|
in Qt 4 and Qt 5. It can be included in the application's .pro file by
|
|
adding:
|
|
|
|
include([path to Qt sources]/tests/manual/diaglib/diaglib.pri)
|
|
|
|
For Qt 4, the environment variable QTDIR may be used:
|
|
include($$(QTDIR)/tests/manual/diaglib/diaglib.pri)
|
|
|
|
The .pri file adds the define QT_DIAG_LIB, so, diagnostic
|
|
code can be enlosed within #ifdef to work without it as well.
|
|
|
|
All functions and classes are in the QtDiag namespace.
|
|
|
|
function dumpText() (textdump.h)
|
|
Returns a string containing the input text split up in characters
|
|
listing category, script, direction etc.
|
|
Useful for analyzing non-Latin text.
|
|
|
|
function dumpTextAsCode() (textdump.h)
|
|
Returns a string containing a code snippet creating a QString
|
|
by appending the unicode value of character of the input.
|
|
This is useful for constructing non-Latin strings with purely ASCII
|
|
source code.
|
|
|
|
class EventFilter (eventfilter.h):
|
|
An event filter that logs Qt events to qDebug() depending on
|
|
configured categories (for example mouse, keyboard, etc).
|
|
|
|
class DebugProxyStyle (debugproxystyle.h)
|
|
A proxy style that wraps around an existing style and outputs
|
|
the parameters and return values of its function calls, useful
|
|
for debugging QStyle.
|
|
|
|
class LogWidget (logwidget.h)
|
|
A Log Widget inheriting QPlainTextEdit with convenience functions
|
|
to install as a message handler.
|
|
|
|
class LogFunctionGuard
|
|
A guard class for use with LogWidget logging messages when a function
|
|
is entered/left (indenting the log messages).
|
|
Can be instantiated using:
|
|
LogFunctionGuard guard(__FUNCTION__) or
|
|
LogFunctionGuard guard(Q_FUNC_INFO)
|
|
|
|
function glInfo() (glinfo.h):
|
|
Returns a string describing the Open GL configuration (obtained
|
|
by querying GL_VENDOR and GL_RENDERER). Available only
|
|
when the QT qmake variable contains opengl.
|
|
|
|
functions dumpNativeWindows(), dumpNativeQtTopLevels():
|
|
These functions du,p out the hierarchy of native Windows. Currently
|
|
implemented for Windows only.
|
|
|
|
function dumpAllWidgets() (qwidgetdump.h):
|
|
Dumps the hierarchy of QWidgets including information about flags,
|
|
visibility, geometry, etc.
|
|
|
|
function dumpAllWindows() (qwindowdump.h):
|
|
Dumps the hierarchy of QWindows including information about flags,
|
|
visibility, geometry, etc.
