fix(deck): re-encode present-but-empty values and keep timestamp precision (#272) (#338)

Marshal dropped a present-but-empty C comment, N mimetype or T value, a bare P card and an empty W body, and wrote D to the millisecond and E to the second, so an artifact carrying any of those did not round-trip through Parse and Marshal.

Carry the presence of a C, N or P card, and of a T value, in unexported Deck/TagCard fields that Parse sets and Marshal reads, and re-emit the W card whenever its body is non-nil (a parsed empty body is a non-nil empty slice). The public API is unchanged: a caller that sets a non-empty value still has it marshalled. Write the D and E timestamps at their writer precision -- millisecond and second -- extended to keep whatever finer fraction the parser read, so a sub-second timestamp survives the round trip. Remove the three FuzzArtifactRoundTrip knownLosses these fixes retire. check-in: 0902561005 user: [email protected] tags: main, trunk

test(conformance): sync-protocol conformance suite (#262) (#311)

* test(conformance): sync-protocol conformance suite (#262)

Checks go-libfossil against draft-fossil-sync-protocol-00, requirement by requirement: 149 requirements, 199 cases. Server cases send raw requests to Repo.XferHandler and, through `fossil http --in`, to fossil(1) on a copy of the same repository; client cases drive the public Sync and Clone against a scripted peer, with fossil(1)'s client run against the same script for most of them; HTTP cases cover redirects, status codes and media types; interop cases run whole exchanges in both directions.

Known failures are marked with the placeholder #0 until their issues are filed, so TestCoverage fails until then.

* test(conformance): sync suite review fixes (#262)

Cases for the requirements that had none where fossil(1) can show the behavior: server-version, the SHA3 gate, shun admission, cookie and cleartext logins, pushed configuration, ci-unlock, cluster brackets, the clone's unversioned catalog and the pull-only message. Two rows added: link ARG handling and the short uvigot.

A fossil(1) disagreement, a harness failure or a deviation other than the one named now fails a case whatever its mark. The server's log output is discarded in the tests.

* test(conformance): mark sync gaps with their issues; drop gaps v0.11.1 closed (#262)

v0.11.1's read gate and redirect policy make seven sync cases conform, so their gap marks are removed. The rest are marked with the issues that track each fix: #296 and #299-#310.

* test(conformance): accept either fossil refusal of a negative clone SEQNO

fossil 2.28's macOS build answers clone 3 -1 with clone_seqno 0 and its Linux build, which CI pins, with the invalid-sequence error alone. The draft leaves the reply open; the case now holds go-libfossil only to sending no content. check-in: 80c72b27c7 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
