| Comment: | 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. |

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 | |
