feat(bisect): refuse a good end below the structural horizon
Section 5.5 has a bisection whose good end lies below the horizon deepen to it before it begins. The path between the ends ran through a boundary phantom and the session went on as if the history were there; Next now refuses first, naming the horizon and the deepen that brings the good end, matching content.ErrBelowHorizon. The library session holds no peer, so the deepen is left to the caller. check-in: ad60dffec8 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 | |
