perf(manifest): stop re-walking delta chains and re-parsing manifests in a rebuild
Rebuilding a clone of the Fossil SCM repository (67,894 artifacts, 21,008 check-ins) took about 3 minutes of which 104 s was parentTreeGap asking content.AvailableByUUID, an uncached delta-chain walk with one SQL statement per node, for every parent of every check-in. It now uses the sweep's availability cache like the rest of the guard. The same sweep parsed each check-in three times (as a child, as its child's parent, as a delta baseline) and rebuilt its file maps. The sweep's content cache now keeps the parsed deck, file views and baseline rid of its few most recent check-ins (Cache.Derived), dropped with the cached bytes on Invalidate and Clear. Derived hits count as reuse in the cascade stats, so the shared-cache regression guard keeps measuring it. The rebuilt event, mlink, plink, tagxref, leaf, filename, cherrypick, orphan, unclustered, unsent, forumpost, attachment, phantom, blob and delta tables are row-for-row identical to the previous code's. check-in: 48ff1f5084 user: [email protected] tags: feat/horizon-cones, trunk | |

test(verify): log peak heap in the corpus rebuild test
The rebuild budget is a wall-time and memory target, and the test only reported time. Sampling HeapInuse beside the run makes a regression in either visible from one -v run. check-in: 7cb4d1aa0d 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 | |
