The fourth and final #error stub in udisksstoragedrive.cpp was in
the bus() function's ATA SATA-vs-IDE detection block. On non-Linux
platforms without udev, this fell through to #error.
Fix: add Q_OS_REDOX guard returning Solid::StorageDrive::Sata.
Redox doesn't have IDE on modern machines; all ata-connected drives
return Solid::StorageDrive::Sata. The ConnectionBus from UDisks2
D-Bus is sufficient for the bus type detection upstream.
All 4 KF6Solid #error stubs are now resolved:
- isHotpluggable() → Q_OS_REDOX: returns isRemovable()
- bus() udevBus → Q_OS_REDOX: uses ConnectionBus from device
- bus() ATA → Q_OS_REDOX: defaults to Sata
- isAppendable() → Q_OS_REDOX: returns false (no optical)
The KF6Solid recipe disabled ALL device backends because 4 #error
directives blocked compilation on non-Linux platforms. This meant
zero hardware discovery on Redox.
Three-part fix:
1. udisksstoragedrive.cpp (2 #errors):
- isHotpluggable(): add Q_OS_REDOX guard returning isRemovable()
(removable USB/eSATA drives are always hot-pluggable)
- bus(): add Q_OS_REDOX guard using ConnectionBus from UDisks2
D-Bus (already available from redbear-udisks)
2. udisksopticaldisc.cpp (1 #error):
- isAppendable(): add Q_OS_REDOX guard returning false
(optical drives are rare on Redox bare-metal)
3. kf6-solid/recipe.toml:
- USE_DBUS=OFF → ON (D-Bus system bus is running)
- BUILD_DEVICE_BACKEND_udisks2=OFF → ON (redbear-udisks is live)
- BUILD_DEVICE_BACKEND_upower=OFF → ON (redbear-upower is live)
- BUILD_DEVICE_BACKEND_fstab stays OFF (no /etc/fstab on Redox)
The original #error fallthrough (for truly unhandled platforms)
remains after the Q_OS_REDOX guard. KF6Solid now has real hardware
discovery via D-Bus instead of compiling with zero backends.
The build-redbear.sh script auto-stashes working tree changes
in nested relibc and base source trees before running the
build. These changes were captured by the failed kernel
build attempt that hit the json-target-spec / kernel rust
toolchain mismatch (fixed in 0.2.5 by creating the local
0.2.5 branch).
Captured changes:
- local/recipes/kde/* : KDE Frameworks 6 source CMakeLists
whitespace changes from the autostash (preserved)
- local/recipes/qt/qtbase/* : qtypes.h whitespace from the
autostash (preserved)
- local/sources/kernel/Cargo.lock : dependency lock from
the kernel relibc rebuild attempt
- local/sources/kernel/src/lib.rs : touched (mtime) by the
build script's touch + make prefix command
This is a bookkeeping commit — the actual code changes
for the threading plan are on the 4 submodule branches
(kernel, relibc, base, libredox) and will be pushed
separately.
0.2.5 branch was created from 0.2.4 (HEAD cd3950072e) to
continue Phase 0 of the multi-threading plan work in a
clean branch.
- Add x11proto to redbear-full.toml package list
- libxau recipe updated with x11proto dependency and custom build script
- Fixes libxau build failure: 'Package xproto was not found'
ROOT CAUSE: Qt6's auto-generated Wayland wrappers pass NULL proxies
to wl_*_add_listener() during initialization. The generated code stores
wlRegistryBind() return value in m_wl_* member without null check,
then init_listener() calls wl_*_add_listener(m_wl_*, ...) which
page-faults at null+8 (write to proxy->object.implementation).
FIX (kded6): wrapper script renames libqwayland.so to .disabled
before launching kded6.real. QT_QPA_PLATFORM=offscreen alone is not
sufficient — Qt6 still loads wayland plugin despite env var.
FIX (libwayland): null guards in redox.patch for wl_proxy_add_listener,
wl_proxy_get_version, wl_proxy_get_display. Blocked from compilation
by pre-existing relibc conflicts (open_memstream, signalfd_siginfo).
FIX (Qt6 wrappers): regex-based null guard insertion proven in concept.
Blocked by TOML recipe format not supporting backslash escape sequences.
Implementation plan: inject null guards via a separate build step script
rather than inline in recipe.toml.
Add redbear-usb-storage-check in-guest binary that validates USB mass
storage read and write I/O: discovers /scheme/disk/ devices, writes a
test pattern to sector 2048, reads it back, verifies match, restores
original content. Updates test-usb-storage-qemu.sh with write-proof
verification step.
Includes all accumulated Red Bear OS work: kernel patches, relibc
patches, driver infrastructure, DRM/GPU, KDE recipes, firmware,
validation tooling, build system hardening, and documentation.
Consolidate the active desktop path around redbear-full while landing the greeter/session stack and the runtime fixes needed to keep Wayland and KWin bring-up moving forward.
