fix(sync): judge pending rows when a received delta fills their basis (#471)
Two review nits. Liveness. A pushed artifact pending on a basis P stayed withheld for good when a pull supplied P as a delta: - Only MarkPending re-rooted, and only for a pushed delta. - Filling a phantom with a delta runs no cascade, so nothing judged the waiting rows if the delta was readable, or moved them to P's own root if it was not. A later fill of that root never reached them. The fix is one hook at the choke point every received delta passes, storeDeltaContent: seedcheck.DeltaStored. - If the stored delta is readable, the rows pending on it are judged. - If not, they move to its chain root, so whatever finally resolves the chain judges them. - It replaces MarkPending's push-only re-root. Error surfacing. JudgeFilled still skips a row whose own bytes cannot be read (a delta that does not apply or fails its checksum, or bytes that are not the artifact named) and judges the rest of the batch. Any other failure is now returned, a broken chain to the filled root included: check-in and tag return it, and the cascade logs it, as it already did for JudgeFilled errors. The separate availability skip went with it. Tests: - A pushed plain file and control artifact pending on a basis that a pull supplies as a delta, on a held basis or on one that arrives in the next round. Both become readable and stop being withheld, are announced on a push-on, and the control artifact is linked. - A row whose content does not decompress is reported. - A checksum-failing row is skipped like an invalid one. - Each hook branch and each error class fails a test when changed. check-in: 584c55d1fd 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 | |
