Tracked in #385.

The server verified the login card first and handled every control card before any data card. A file card ahead of its push card was stored, and cards ahead of a successful login got the login's capabilities. Cards are now handled in one in-order loop, as fossil's page_xfer reads them. A request holding an invalid clone sequence is first walked without side effects, which stands in for fossil's whole-request rollback.

A refused push without an earlier pull now resets and answers "not authorized to write"; a refused pull resets, answers "not authorized to read" and ends card processing (sync-protocol-01 Section 6.6).

An accepted push now asks for the server's phantoms after the card loop, at most 500, skipping what the client asked for, shunned names and private ones outside a private sync, as request_phantoms does. A pushed igot makes a phantom instead of drawing a gimme on the spot.

A clone reply card the client cannot read ends the reply-card loop instead of aborting: the session goes on, the second clone round is still made, and the clone then fails naming the card.

The conformance matchers that accepted "push denied" and "pull denied" are narrowed to the draft's text, and new cases put output ahead of a refusal and cards ahead of the push or login they depend on. check-in: 3beb6eeb15 user: [email protected] tags: main, trunk

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
