-# Docker test-build script - design
-
-Date: 2026-07-13
-
-## Purpose
-
-A single bash script that verifies an already-published SBo package still
-builds cleanly on a target Slackware version, inside a throwaway docker
-container. This is the "test-build" step of this repo's maintenance loop
-(track upstream -> bump -> **test-build** -> make tarball).
-
-The container is disposable, so unlike a real `slackrepo build` this runs
-directly (no host install), and Claude may run it (per the repo's
-`Who builds SlackBuilds` exception).
-
-## Scope and non-goals
-
-- One target package per run: `test-build <pkg>`.
-- Two Slackware targets: `-current` (default) and `15.0` (`--stable`).
-- Resolves the target's SBo dependency tree from the LOCAL SBo tree, builds
- deps then target in the container, reports, discards everything.
-- NOT a redistributable-package builder. The container's built `.txz` is
- throwaway; the SBo submission tarball is made separately (post-commit hook)
- only after a green run.
-- Does NOT wrap slackrepo or sbo-batch-test. It REUSES sbo-batch-test's
- resolver + build logic, adapted, but is an independent script.
-- Shares the host kernel (docker). No kernel-module build claims.
-
-## Why not the overlay approach (sbo-batch-test)
-
-`sbo-batch-test` already resolves deps + builds + reports, but against a
-LOCAL overlayfs over a 15.0 base. In docker the container IS the disposable
-base, and overlayfs-over-docker-storage (itself overlayfs) is fragile. So we
-drop the overlay layer and build directly in the container. We port
-sbo-batch-test's dep resolver and its `build_one` chroot heredoc
-(download -> md5 -> build -> installpkg -> status token) into a `docker run`.
-
-## Architecture
-
-Single self-contained bash script (`test-build`, location TBD in
-implementation - likely `.extras/`). Host does resolution + orchestration;
-the container does the actual building.
-
-```
-host: parse args, load config
-host: pick version -> image tag + SBo tree
-host: resolve dep tree (local tree, topo sort) [ported from sbo-batch-test]
-host: apply current-vs-stable overrides
-host: print final build order, Y/n confirm (--yes: still prints first)
- docker run --rm -v <tree>:ro -v <pkg>:ro -v <cache/digest>:ro <image>:
- for each dep in order:
- cache hit (version match) -> installpkg from cache (CACHED)
- else -> download/md5/build/installpkg + cache
- target: download/md5/build/installpkg (always fresh)
- target: sbopkglint on the built .txz
-host: collect per-package results, print color summary
-container discarded (--rm)
-```
-
-### Images (external input, not built by this script)
-
-The script does NOT build images. It consumes a ready image per version,
-tagged locally:
-
-- current: `sbo-testbuild:current`
-- 15.0: `sbo-testbuild:15.0`
-
-Each image is a FULL, patched Slackware install (SBo tests against a full
-install; a minimal base causes false "missing dependency" results, a lesson
-from sbo-batch-tester) plus `sbo-maintainer-tools` (for `sbopkglint`) and
-`sbopkg` configured to that version's SBo repo (`:current` -> -current repo,
-`:15.0` -> 15.0 repo).
-
-**How the images are produced is out of scope for this script.** A separate
-nightly job (a LAN machine, images stored on the NAS, later served from a
-local registry) builds and refreshes them. That builder is its own tool,
-specced separately.
-
-For now the script assumes the tagged image is present locally: it runs
-`docker run` against the tag and errors with a clear message if the image is
-missing (pointing at the image-builder job). When the local registry exists,
-a `docker pull` of the tag slots in ahead of the run via the same config,
-no other change.
-
-Per-run cost is just the SlackBuild's own build time + ~1s container start.
-
-### Config (external file)
-
-`~/.config/sbo-testbuild/config`, empty defaults in-script, sourced if
-present (same pattern as sbo-batch-test). Keys:
-
-```sh
-SBO_TREE_CURRENT=/path/to/SBo-current # local SBo tree, -current
-SBO_TREE_STABLE=/path/to/SBo-15.0 # local SBo tree, 15.0
-IMAGE_CURRENT=sbo-testbuild:current # ready image tag (built elsewhere)
-IMAGE_STABLE=sbo-testbuild:15.0
-LOG_ROOT=/path/to/logs
-PKG_CACHE=/path/to/cache # dep cache; empty = disabled
-```
-
-The version flag selects BOTH the image and the tree together (default
-current; `--stable` / `15.0` switches both), so tree and image never mismatch.
-
-### current-vs-stable overrides
-
-A data file next to the config, `~/.config/sbo-testbuild/overrides`. It
-encodes the known deltas between building on 15.0 and on -current. Applied
-ONLY when the target version is `-current` (15.0 is the SBo baseline). Three
-rule kinds:
-
-```
-# dep present in 15.0 but already in -current base -> drop from order
-drop: rust
-# dep renamed on -current -> map old -> new before lookup
-rename: python3-foo -> foo
-# dep removed from the -current tree -> fetch from SBo instead of local tree
-fetch: somelib
-```
-
-Format: one rule per line, `kind: value` (rename uses `old -> new`), `#`
-comments and blank lines ignored.
-
-### Dependency resolution + unknown deps
-
-Resolver is ported from sbo-batch-test (`resolve_target` / `_resolve_visit`,
-DFS topo sort + cycle detection, `installed_in_base` check). Runs on the host
-against the selected tree.
-
-After resolving and applying overrides, every dep must be accounted for:
-in base, in the tree, or covered by a `fetch:` rule. If a dep is none of
-those (and no rule covers it), the script **stops before building**, reports
-it as UNMET, and asks the user to add an override rule and rerun, or abort.
-Never silently skip or guess.
-
-### Confirmation
-
-Always print the final build order before building, with overrides marked
-(dropped / renamed / fetch). Then `Y/n` to proceed. `--yes` skips the prompt
-for non-interactive/agent runs but STILL prints the order first.
-
-`--dry-run` resolves, applies overrides, prints the order, and exits without
-building (no confirm).
-
-### Build in container (ported from build_one)
-
-Deps then target, in order. For each package, inside the container:
-
-1. download sources (arch-specific `DOWNLOAD_x86_64`/`MD5SUM_x86_64` when
- present, else `DOWNLOAD`/`MD5SUM`)
-2. verify md5
-3. `bash <pkg>.SlackBuild` with `OUTPUT` forced to a known dir
-4. `installpkg` the resulting `.txz`
-5. write a status token read back by the host
-
-`fetch:` deps (removed from the -current tree) are pulled via the baked-in
-`sbopkg`, which points at the image's matching SBo repo; everything else
-builds from the mounted local tree. Start light: handle only the few known
-`fetch:` cases, add rules as real packages need them.
-
-### Dependency cache
-
-Ported from sbo-batch-tester (`cache_decision`/`cache_path`/`cache_store`/
-`version_of`). A host dir caches built dep packages so consecutive runs reuse
-them instead of rebuilding the whole tree.
-
-- Config `PKG_CACHE=/path` enables it; empty (default) disables. `--no-cache`
- forces a full rebuild for one run.
-- Bind-mounted read-only into the container; a cached dep is `installpkg`ed
- instead of built (status `CACHED`). Storing is host-side: a freshly built
- package is written to `OUTPUT` (a mounted dir the host reads back), and the
- host copies it into the cache after the build (`cache_store`), so the cache
- mount stays read-only. The **target always builds fresh** and refreshes its
- own cache entry; it is never `CACHED`.
-- Key = prog + version (build/arch/tag ignored). Layout mirrors the SBo tree:
- `$PKG_CACHE/<image-digest>/<category>/<prog>/<prog>-<ver>-...txz`, one .txz
- per prog.
-- **Invalidation by image digest.** The cache is namespaced by the running
- image's digest. When the digest changes (image updated by the nightly job),
- the old namespace is stale: its deps were built against the previous image,
- so they are ignored and rebuilt once under the new digest. This also keeps
- the `:current` and `:15.0` caches separate (different images, different
- digests). Old digest namespaces can be pruned.
-- A per-dep version bump (`bump: OLD -> NEW`) rebuilds and re-caches that dep.
-- Build-order line shows the outcome per dep: `cached (1.1)`,
- `rebuild: 1.0 -> 1.1`, or `build (new)`; `--dry-run` shows the same without
- building.
-
-### Target lint
-
-After the target builds, run `sbopkglint` on its `.txz` (tool baked into the
-image). Fail-soft: findings reported but do not change SUCCESS; missing tool
-prints a skip note. Target only (deps are vetted).
-
-### Report
-
-Per-package status + a color summary (screen) and a plain-text log under
-`LOG_ROOT/<timestamp>/`:
-
-```
-<timestamp>/
- <prog>.log per-package full build/install output
- summary.log plain recap
- build-order.txt the resolved+overridden order actually used
-```
-
-Status values (from sbo-batch-test):
-`SUCCESS CACHED DOWNLOAD-FAILED MD5-MISMATCH BUILD-FAILED INSTALL-FAILED
-BLOCKED-BY-DEP UNMET-DEP`. `CACHED` = a dep installed from the cache instead
-of rebuilt (target is never CACHED). `%README%` deps flagged as a reminder,
-not built.
-
-A fully green run tells the user it is safe to make the SBo submission tarball
-on the host (the container is no longer needed).
-
-## Options (planned)
-
-| Option | Effect |
-|--------|--------|
-| `--stable` / `15.0` | Target 15.0 (image + tree). Default is -current. |
-| `--dry-run` | Resolve + apply overrides + print order, no build. |
-| `--yes` | Skip the Y/n confirm (still prints the order). |
-| `--no-cache` | Rebuild all deps this run, ignore/refresh the cache. |
-| `--no-color` | Disable ANSI (auto-off when not a TTY). |
-| `-h`, `--help` | Usage. |
-
-## Self-check
-
-A `test-logic.sh` (host, no docker) covering the pure logic:
-
-- dep topo order + cycle detection (ported tests from sbo-batch-test)
-- override application: drop removes, rename maps, fetch marks source
-- unknown-dep -> UNMET stop
-- BLOCKED-BY-DEP propagation
-- cache decision: `cached`/`rebuild: OLD -> NEW`/`build (new)`, digest
- namespacing, version-bump eviction (ported from sbo-batch-tester's tests)
-
-Docker/build/installpkg paths are out of the self-check's reach (verified by
-running a real target), same boundary as sbo-batch-test.
-
-## Resolved decisions
-
-- **Image**: a ready FULL-install image per version (full pkg set +
- `sbo-maintainer-tools` + `sbopkg` on that version's repo), built by a
- separate nightly job, NOT by this script. Script consumes it by tag.
-- **Missing image**: error clearly, point at the image-builder job. A local
- registry `docker pull` slots in later via the same tag, no script change.
-- **`fetch:`**: via the image's `sbopkg` (per-version repo). Start with only
- the few known cases; grow the override rules as needed.
-- **Script location**: `.extras/` (a tool, not a package).
-
-## Out of scope / later
-
-- The nightly image-builder (full-install + tools + sbopkg per version, NAS
- storage, local registry). Its own tool, specced when the LAN machine is set
- up.
-- Local registry pull step in this script (slots into the same config tag).
