Phase 1 — Hash-based cache invalidation:
- DepHashes struct: BLAKE3 hash of each build dep stored in dep_hashes.toml
- collect_current_dep_hashes(): reads blake3 from dep .toml metadata
- dep_hashes_changed(): compares stored vs current hashes
- Replaces mtime comparison as primary cache invalidation check
- Mtime fallback preserved for backward compatibility (no dep_hashes.toml)
- --force-rebuild CLI flag bypasses cache entirely
Phase 2 — Binary store cache lookup:
- repo_builder publishes dep_hashes.toml alongside .pkgar/.toml in repo/
- When target/ is missing but repo/ has the package, restores stage
artifacts by extracting pkgar, copying toml + dep_hashes.toml
- Auto-generates auto_deps.toml from repo depends field
- Only applies to non-remote, non-force-rebuild builds
See local/docs/BUILD-CACHE-PLAN.md for full architecture.
- apply-patches.sh: add signature-marker checks for build-system patches
to handle cases where reverse-check fails but patch is already applied
- test-baremetal.sh: auto-disable TUI when stdout is not a terminal;
pass CI=1 to make
- test-live-iso-qemu.sh: pass CI=1 via env to prevent repo cook panic
- scripts/run.sh: auto-disable TUI when stdout is not a terminal;
pass CI=1 to qemu launch
- repo.rs: improve TUI initialization error messages (raw mode + alternate
screen) and rustfmt cleanups
- config.rs: auto-detect TTY presence for TUI enablement; use is_terminal()
instead of relying solely on CI env var
Derivative of Redox OS (https://www.redox-os.org) adding:
- AMD GPU driver (amdgpu) via LinuxKPI compat layer
- ext4 filesystem support (ext4d scheme daemon)
- ACPI fixes for AMD bare metal (x2APIC, DMAR, IVRS, MCFG)
- Custom branding (hostname, os-release, boot identity)
Build system is full upstream Redox with RBOS overlay in local/.
Patches for kernel, base, and relibc are symlinked from local/patches/
and protected from make clean/distclean. Custom recipes live in
local/recipes/ with symlinks into the recipes/ search path.
Build: make all CONFIG_NAME=redbear-full
