fix(sync): refuse pushed seeds by hash; judge only what a fill grounds (#471)
Horizon F.1, push side, and the fourth review's blocking finding. Refusal by hash: - seedcheck keeps two store-local tables, carried by no config group: seedpending(rid, root) and seedrefused(uuid). - A seed judged after the request that pushed it, because a later push, pull, check-in or tag filled its basis, has its hash refused. Its rows are deleted by Sweep, and only where no receive pass holds rids: end of request, end of sync, check-in, tag and rebuild. A deleted rid is reused by the next row, and a pass's caches are keyed by rid. - Until swept, such a row is withheld and never linked. A delta on a refused seed is left unreadable and pending under no root. - requestPhantoms never asks for a refused hash. ownSeedReadable refuses a re-push of one, and a full-text re-push is refused on its bytes. - A purge still forgets pending rows (ForgetDeleted). Refusals are keyed by hash, so rid reuse cannot pass them on. Judging only what a fill grounds: - JudgeReadable rescanned every pending row on each fill. A pusher could plant dangling deltas without bound and make every later fill pay for all of them. - Pending rows now record the root of their basis chain, re-rooted when that root is itself stored as a dangling delta. - JudgeFilled judges only the rows pending on the rids just stored, and reports how many it examined. - Callers: AfterDephantomize and its batch, manifest.Checkin (its files and manifest) and tag.AddTag. linkArtifact still judges a pending row it reaches, caching which tables exist per transaction. - The sweep no longer judges. A seed-shaped artifact received by pull or clone stays ordinary, per the 0.7.1 B.2. Docs and the HZ-5.2-4 scope note cite F.1. Tests: - A seed package test: one fill examines its own row, not 200 planted elsewhere. Run as a rescan mutant, it fails. - A tag whose control artifact is a seed's basis refuses the seed. - The link step refuses a seed made readable by a raw store. - A re-push refused by hash, and an igot of the hash not gimme'd. - A delta on a refused seed withheld. - A purged pending rid reused by an innocent blob. - Disabling any judge call (cascade, check-in, tag, link) or any Sweep call (request, sync, check-in, tag) fails a test. check-in: ed5e3ce5b5 user: [email protected] tags: main, trunk | |

feat(sync): origin refuses a pushed seed by label or shape (#471)
Horizon §5.2.3 as the zit 0.7.1 erratum words it. A pushed control artifact is a seed when its U card is the origin's own label (go-libfossil) or it carries a horizon-seed T card under any label. Full text is judged as it arrives. A delta is judged on its expanded content at the end of the request, so a delta whose base arrives later in the same request is caught. A delta never made readable is not identified and stays a dangling delta. The refusal is atomic: the request rolls back, and the reply is the single error card "seed refused: a seed is private to the clone that holds it; it is never pushed". The horizon-seed name match is kept as an extra check, and now refuses loudly the same way instead of silently dropping the file. Conformance cases for HZ-5.2-4 cover full text, a delta against a held base, a late delta, the shape under a foreign label (full and late), and a foreign label with no binding card, which is stored. An HZ-5.7-2 case covers the stale-seed check on a late delta. An interop case has zit 0.7.0 push such an artifact to a go-libfossil origin and get refused. check-in: 1afe809b01 user: [email protected] tags: main, trunk | |

Initial open source release
libfossil is a pure-Go implementation of the Fossil SCM, reading and writing the same .fossil SQLite repository format as upstream Fossil. This is the first public release of code that previously lived in a private repository. The module path is github.com/danmestas/libfossil and the binary is named libfossil to avoid $PATH collisions with upstream fossil. Included: - Repo lifecycle (create, clone), checkout/checkin, timeline, merge, diff, annotate, shun, tag, branch, bisect, stash, undo/redo - Sync-over-HTTP protocol (client and handler) - Two SQLite drivers: modernc (pure Go, default) and ncruces (wasm-capable) - Observer interfaces (SyncObserver, CheckoutObserver) with an optional OpenTelemetry implementation in observer/otel (separate submodule) - Deterministic simulation testing harness with BUGGIFY fault injection - Kong-based embeddable CLI under cli/ and a standalone binary under cmd/libfossil/ check-in: f5744359d3 user: [email protected] tags: trunk | |
