feat(sync): refuse a push whose branch cancellation names a stale seed
A check-in that creates a branch cancels its parent's branch tag by the name its clone derived, and under a structural horizon that name came from the seed. Section 5.7 has the origin check it against its own derivation: the handler now looks at each check-in a push stored, once crosslinked, and when the parent is on another branch here it rolls the whole push back with an error naming the stale seed and the parent's branch, spelled as zit's pushSeedCancelFault spells it. A check-in is admitted when the push or the store holds a control artifact cancelling the parent's real branch on it, and so is one whose parent this origin cannot place. zit's check reads only the push for the correction; this one also reads the store, as the draft allows. Interop runs both ways against zit 9bf7ebfe0f. check-in: 8f89198ca1 user: [email protected] tags: feat/horizon-cones, trunk | |

feat(sync): answer and ask the horizon merge-base query
A structural clone cannot compute a merge base whose ancestry lies below its horizon, so draft-fossil-horizon-00 section 6.2.4 lets it ask the origin with pragma horizon-mergebase A B. The origin answers in its pull reply, ahead of the igots where zit places it, with the base or - for no common ancestor, and only for check-ins it holds. Section 8 bounds the walk: merge.FindCommonAncestorWithin carries the held-set walk's visited-node bound and the query goes unanswered past it. The client asks once, in the first request after the cursor, through SyncOpts.MergeBaseOf and reports the answer in the result. Interop runs both ways against zit 9bf7ebfe0f. check-in: 5612ac9771 user: [email protected] tags: feat/horizon-cones, 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 | |
