The v6.0 build-system hardening arc lands 5 of the 10 improvements
proposed in local/docs/BUILD-SYSTEM-IMPROVEMENTS.md. All scripts
have unit tests (62 -> 86, all pass in <1s) and the new 'lint-recipe'
Gitea Actions job runs on every PR.
Per-recipe audit & lint scripts (catch R1/R2 violations BEFORE cook):
* audit-patch-idempotency.py — verifies external patches in
local/patches/ still apply against the upstream pinned rev.
Caught 1 real bug on first run: libdrm/02-redox-dispatch.patch
hunk at xf86drm.c:321 no longer matches libdrm-2.4.125.
* audit-kf6-deps.py — fetches upstream, scans for
find_package(KF6Xxx REQUIRED), compares to recipe deps. Catches
missing + dead dependencies in every kf6-* and qt* recipe.
* classify-cook-failure.py — 17-rule cook-failure classifier.
10-30s diagnosis vs 5-10min manual. exit code is intentionally
inverted (0=novel failure, 1=known fix) for CI signal.
* lint-recipe.py — 7-rule recipe lint: R1-NO-PATCH-FILE,
R1-PATH-SOURCE, R2-INLINE-SED, R2-PATCHES-DIR-UNUSED,
NO-LEGACY-MAKE, R1-LEGACY-APPLY-PATCHES, DEP-NOT-FOUND.
1.1s for 171 recipes (down from 60s+ in v1 via recipe-index
precomputation). Strict mode promotes warnings to errors.
Build-system convenience:
* repair-cook.sh — incremental-build optimizer.
Equivalent to 'repo cook <pkg>' but with a fast-path that
skips configure when CMakeCache.txt is newer than source AND
external patches haven't changed. 30-60s vs 5-10min on KF6
recipes. make repair.<pkg> / make clean-repair.<pkg> targets.
* migrate-kf6-seds-to-patches.sh — migration skeleton for
converting 56 inline 'sed -i' chains across the KF6 recipes
to durable external patches in local/patches/<name>/.
Gitea Actions (host-execution, no Docker):
* .gitea/workflows/build-system.yml — 8-job pipeline:
unit-tests, lint-offline, lint-network (nightly),
lint-recipe (NEW), lint-docs, build-mini, build-full,
smoke (QEMU boot).
* .gitea/RUNNER-SETUP.md — one-time Manjaro/Arch host setup.
Build script hardening:
* build-redbear.sh — when a low-level source (relibc,
kernel, base, bootloader, installer) is newer than its pkgar,
clean build/ and sysroot/ across all recipes too. Low-level
package changes leave autotools packages (pcre2, gettext,
libiconv, ...) with stale configure/libtool scripts referencing
the old runtime, causing 'libtool version mismatch' and
'not a valid libtool object' errors. Cleaning forces
re-configuration; stage/ and source/ are preserved so the
cookbook skips unchanged packages that don't use autotools.
* Makefile — wire lint-cook-failure,
lint-cook-failure-explain, lint-recipe, lint-recipe.%,
lint-recipe.strict, lint-recipe.%.strict, repair.%,
clean-repair.%, test-lint-scripts[-quiet]. Replace the
legacy 'validate-patches' target with a deprecation notice
pointing at validate-sources.
Documentation:
* BUILD-SYSTEM-IMPROVEMENTS.md — mark #2 and #5 DONE; full
implementation notes; updated Make-targets table.
* BUILD-SYSTEM-V6-HARDENING-POSTMORTEM.md (NEW) — 226-line durable
record of the 8-session arc: 32 findings categorized, 5 P0
audit-script bugs fixed, 6 over-broad multi-pattern rules
discovered + fixed, test coverage 86/86 in <1s, 7/10
improvements DONE.
* SCRIPT-BEHAVIOR-MATRIX.md — apply-patches.sh row marked
LEGACY/ARCHIVED; build-redbear.sh row no longer claims to
call it.
* boot-logs/README.md (NEW) — frozen-evidence policy:
'do not edit' rule for REDBEAR-FULL-BOOT-*-RESULTS.md files.
* libdrm/02-redox-dispatch.patch.README (NEW) — 8-step regen
procedure for the broken hunk.
Cleanup:
* local/cache/README.md deleted (1-line placeholder).
* legacy 'make validate-patches' target removed.
Per build-system improvement #5: lint-recipe.py's first run on
the live tree surfaced 1 broken-patch reference (redbear-sessiond),
1 dangling cookbook_apply_patches call (tc), 19 sed -i calls in
sddm (warning — cookbook_apply_patches present, drop-x11.py
migration in progress), 4 sed -i calls in qt6-wayland-smoke
(uncovers the same bug class the libwayland fix prevented).
- Removed broken netinet/in6_pktinfo_compat.h include from git tracking
- Restored pkgar signing keys from local/cache/keys/
- Restored 100 pkgars from packages/ backup with matching keys
- Mini ISO builds successfully (1.5 GB)
- Full ISO needs COOKBOOK_OFFLINE=false for missing tarballs
Platform prerequisite status:
- Qt6::Sensors: BUILT (v6.11.0, 520KB pkgar, dummy backend)
- libinput: BUILT (v1.30.2, with libevdev v1.13.2 + linux-input-headers)
- QML/Quick JIT: still disabled on Redox (blocks real KWin binary,
kirigami, plasma-framework)
KWin: now attempts real cmake build with Sensors + libinput deps
enabled. Falls back to redbear-compositor shim on cmake failure
(QML/Quick gate). Previously kwin was pure stub — now it's a
bounded build attempt with fallback.
Enabled in config (new this session):
- qt6-sensors, libevdev, libinput, kdecoration, kf6-kcmutils
Previously OOTB dependencies now resolved:
- libevdev → libinput → KWin real build path opened
- linux-input-headers → libevdev → libinput chain
- qt6-sensors → KWin Sensors dependency satisfied
pkgar signatures depend on build/id_ed25519 keys.
Without keys, cached pkgar files are unverifiable after key rotation.
Keys now stored in local/cache/keys/ for cache restore.
Red Bear is a fork/overlay on top of Redox. The upstream build
system wasn't designed for forks — it loses all cached stages on
make clean with no recovery path.
This commit adds a git-tracked build cache:
- local/cache/pkgar/{pkg}/stage.pkgar — per-package cache files
- cache-sync.sh: sync built packages → git-tracked cache
- cache-sync.sh --restore: restore cache → recipe targets
- cache-sync.sh --commit: sync + git commit
- Auto-restore before build, auto-sync after build
Cache survives: make clean, make distclean, git clone, upstream rebase.
Recovery from clean: seconds (restore from git) vs hours (full rebuild).
Adds comprehensive build cache snapshot and restore for overlay OS.
Problem: Upstream Redox build system is single-stream — make clean
destroys cached stage.pkgar files permanently. Build can't recover
without full from-scratch rebuild (2-4 hours).
Solution: Red Bear cache system provides:
- snapshot-cache.sh: Save all stage.pkgar to local/cache/
- restore-cache.sh: Restore from snapshot after make clean
- Auto-restore: Makefile auto-restores cache before build
- Essential cache: Pre-built caches for boot packages tracked in git
- Cookbook fixes: Missing deps trigger rebuild instead of crash
With cache restore, make clean recovery is measured in seconds,
not hours.
Gaps fixed in cookbook:
- modified_all_btree: missing dep → UNIX_EPOCH (rebuild trigger)
- sysroot install: missing dep → skip + rebuild
