Slice 2 of the self-update story. Tagging a release on main now
produces a downloadable self-update payload on the Forgejo releases
page, and a running box can pull it down, verify it, atomically swap
to the new version, and health-check the result.
New pieces:
- scripts/build-release-tarball.sh <version> — packages the furtka/
package + bundled apps/ + a root-level VERSION file as
dist/furtka-<version>.tar.gz, plus a .sha256 sidecar and a
release.json metadata blob.
- scripts/publish-release.sh <version> — uses the Forgejo v1 API to
create a release (body pulled from the CHANGELOG section for this
tag, pre-release auto-flagged on -alpha/-beta/-rc) and upload the
three assets sequentially. Needs \$FORGEJO_TOKEN.
- .forgejo/workflows/release.yml — tag-triggered, runs both scripts
with the new \$FORGEJO_RELEASE_TOKEN repo secret.
- furtka/updater.py — check_update, prepare_update, apply_update,
run_update, rollback. Atomic symlink swap, sha256 verify (TOCTOU-
safe: re-hashes on-disk file), health-check post-restart with
auto-rollback on failure, stage-by-stage progress persisted to
/var/lib/furtka/update-state.json so the UI can poll independent
of the (restarting) API process. Path overrides via FURTKA_ROOT /
FURTKA_STATE_DIR / FURTKA_LOCK_PATH so tests pin a tmpdir.
- furtka/cli.py — \`furtka update [--check] [--json]\` and
\`furtka rollback\`.
- tests/test_updater.py — 15 tests: version compare, sha256 verify,
tarball extract (including traversal refusal), lockfile, apply
happy + rollback paths, rollback CLI, check_update with stubbed
Forgejo.
- iso/build.sh — writes VERSION at the tarball root so the install
path matches the self-update path (previously assumed only the
release script did this).
RELEASING.md now points at the automated flow — no more manually
clicking "Create release" on the Forgejo UI.
