perf(content): read the memo's trees with its graph, as interned id sets
The origin classification memo now reads the F cards of every tree in the store once, with its references, and extends them by appended check-ins (draft-fossil-horizon-00 §6.2, HZ-6.2-10). Blob names are interned to uint32 ids, each tree's file set is a sorted delta-varint id list, and a full manifest is kept as its symmetric difference from the previous full manifest read, at most 15 links from a piece kept whole, decoded through a 16-entry LRU per view. A store whose index would pass memoTreeBytes keeps none and falls back to the bounded cache of walked trees. On a clone of fossil-scm.org the trees take 11 MiB (the walked-tree cache held 50 MiB for two horizons), the memo's retained heap halves and peak in-use heap drops from 345-524 MiB to about 170 MiB. Tracked in #463. check-in: 1cb9e11a65 user: [email protected] tags: main, perf/memo-tree-encoding, 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 | |
