BREAKING CHANGE: The patch-based build system is removed. All Red Bear source now lives in local/sources/<component>/ as git repos. Changes: - src/recipe.rs: remove patches field from SourceRecipe::Git/Tar, add Local variant - src/cook/fetch.rs: delete fetch_apply_patches, validate_patches, normalize_patch, fetch_compute_patches_hash, fetch_write_patches_state, fetch_patches_state_stale, fetch_validate_patch_symlinks, fetch_is_patches_newer. Simplify fetch and fetch_offline. Remove recipe_has_patches. Add Local source handler. - src/bin/repo.rs: remove validate-patches command and handle_validate_patches - 70 recipe.toml files: remove patches arrays, convert core recipes to Local source - 272 .patch symlinks deleted from recipe directories - integrate-redbear.sh: replace patch symlink logic with source fork validation - Makefile: replace validate-patches with validate-sources target - AGENTS.md: remove 369 lines of patch documentation, add source ownership model - local/docs/PATCH-GOVERNANCE.md: deleted (replaced by SOURCE-OWNERSHIP-MODEL.md) - local/docs/SOURCE-OWNERSHIP-MODEL.md: new canonical reference - local/sources/: Red Bear fork repos created (kernel, relibc, base, bootloader, installer) from frozen 0.1.0 pre-patched archives - .gitignore: exclude local/sources/ (separate git repos) - create-forks.sh: new script for initializing fork repos Build: cargo check passes (5 warnings, 0 errors). Developer workflow is now: edit local/sources/ → repo cook → test. No patches.

Red Bear OS Source Ownership Model
Effective: 2026-06 (migrated from patch-based build system) Replaces: PATCH-GOVERNANCE.md, AGENTS.md patch sections
What Changed
Red Bear OS migrated from a patch-based build system to direct source ownership.
Previously, we maintained upstream Redox source + 341 patch files applied at build
time. Now, we maintain our own git forks of every component under local/sources/.
The source IS the source. No patches. No indirection. Edit, build, commit.
Where Source Lives
| Component | Fork Location |
|---|---|
| Kernel | local/sources/kernel/ |
| C library (relibc) | local/sources/relibc/ |
| Userspace drivers (base) | local/sources/base/ |
| Bootloader | local/sources/bootloader/ |
| Installer | local/sources/installer/ |
| RedoxFS | local/sources/redoxfs/ |
| User utilities | local/sources/userutils/ |
Additional components have individual forks as needed. Each fork is a git repository initialized from the frozen Redox 0.1.0 baseline with all Red Bear modifications applied as the initial commit.
Daily Workflow
Make a change
vim local/sources/relibc/src/header/sys_signalfd/mod.rs
./target/release/repo cook relibc
make qemu CONFIG_NAME=redbear-mini
git -C local/sources/relibc commit -m "relibc: fix signalfd edge case"
Integrate upstream improvements
Upstream Redox is a reference. When they improve something you want:
cd local/sources/relibc
git remote add upstream https://gitlab.redox-os.org/redox-os/relibc.git
git fetch upstream
git log upstream/main --not main --oneline
# Read each interesting commit. Understand it. Port manually.
git commit -m "relibc: port upstream fix (ref: redox <sha>)"
Release
Tag each component repo with the release version:
git -C local/sources/kernel tag v0.2.3
git -C local/sources/relibc tag v0.2.3
git -C local/sources/base tag v0.2.3
# Build from tags
Why This Is Better
| Before (Patches) | After (Source Ownership) |
|---|---|
| 341 .patch files to manage | 0 patches. History in git. |
| 5-step edit cycle (edit → diff → save → wire → validate → build) | 2-step (edit → build) |
| New developers must learn patch system | Standard git workflow |
| make clean could destroy unpatched work | Work lives in git repos |
| Mega-patch corruption and hunk failures | Git merge conflicts (standard, tool-supported) |
| ~5,000 words of patch documentation | ~300 words of source model documentation |
Historical Note
The old patch files in local/patches/ are preserved as historical reference.
Each patch was converted into the initial commit of its corresponding fork repo.
To trace a change: git log local/sources/base/ — commit messages reference the
original patch filenames.
Recipe Configuration
Recipes that use Red Bear forks configure their source as a local path:
[source]
path = "../../../local/sources/base"
Recipes for non-forked packages (upstream libraries, tools) use standard git or tar sources without patches — the source is fetched directly.
