fix(manifest): link a cherrypick source that arrives after its child
A check-in crosslinked before its cherrypick ('+') source arrived kept no cherrypick row, since insertCherrypicks skipped a source it could not find, and so never received the auxiliary mlink rows for that source: the late-arrival pass walked plink alone, which holds no cherrypick edges. Canonical skips a missing source the same way and relies on the rebuild its clone ends with; a clone here links as artifacts arrive and has no such rebuild. A clone of fossil-scm.org's repository was left with 139 cherrypick rows and 262 mlink rows fewer than its origin. insertCherrypicks now reserves a missing source as a phantom, as plink does for a missing parent, and the late-arrival pass (linkPlinkChildren, now linkLateChildren) walks the source's cherrypick children with plink's. check-in: 28f343c11b user: [email protected] tags: feat/horizon-cones, trunk | |

perf(serve): memoize a clone request's forwardable sources
forwardableSource reads a row, its shun and private state and the tree gate each time it is asked, and a clone round asks about the same rows from every chain walk and every sentEarlier search: a twelfth of a dense clone's CPU. A request reads one snapshot, so the verdicts are kept for its duration. TestCorpusClone logs an origin error, which its client sees only as an HTTP status. check-in: b9ec3c086e user: [email protected] tags: feat/horizon-cones, trunk | |

perf(manifest): keep available verdicts across a clone's links
ReceiveLinker.LinkStored made a fresh availability cache for every blob it linked, so each deferred check-in's retry walked every F card's delta chain again; after the receive fixes that walk was a sixth of a dense clone's CPU. Only the unavailable verdicts can go stale during a receive, which only adds content, and a clone whose round fails stops receiving, so LinkStored now drops just those (AvailabilityCache.ForgetUnavailable) and keeps the rest. check-in: a30155185d user: [email protected] tags: feat/horizon-cones, trunk | |
