perf: carry a cone clone's forwarded delta chains across rounds
The server's cone walk sends an in-cone file version as a delta with the chain of newer versions ahead of it as its bases. Each round restarts the walk from the clone's cursor, so every later round that reached one of those versions at its own check-in sent it again. The walk's cookie now names each chain a send forwarded: its head, length and an FNV-64 checksum of its rids. The next round rebuilds the chain from the store's delta table, counts its rids as sent, and drops it when the checksum no longer matches, so a store re-deltified mid-clone can never pass off a base the client was not sent. A run loses the leading rids the walk reaches, and the cookie carries at most 1,024 runs; one dropped is only sent again. On a copy of fossil-scm.org's repository a cone clone of src now receives 72,835 blobs to hold 56,262 (main: 100,212); the clones verify identically. check-in: 9d266a0f51 user: [email protected] tags: main, perf/cone-clone-resend, 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 | |
