fix(serve): charge a walked-past clone row what a dense round would
A cone-aware clone charged each row it walked past at its expanded size, while a dense round charges the bytes it sends, a row's stored delta. A sparse round of fossil-scm.org's repository covered a hundredth of a dense round's rows and the clone ran out of rounds. SC-6.2-1 bounds the walk as a dense clone bounds its batches, so a walked-past row is now charged its stored size, read from the four-byte prefix of blob.content without inflating it. check-in: 835557d4b1 user: [email protected] tags: feat/horizon-cones, trunk | |

perf(serve): classify a cone walk's rows without expanding every file
A cone-aware clone classifies each row it walks, and each served delta's base, by parsing the row's bytes. The handler has no content cache in production, so every row's whole delta chain was expanded and hashed again; on fossil-scm.org's repository that was the cone clone's first round, unfinished after 20 minutes. The walk now reads, once per request, the rows the crosslink tables prove to be file content (named by mlink, claimed by no artifact table; a store that has seen a sub-manifest answers nothing) and classifies only the rest, through its own unchecked cache: classifying serves nothing, and the bytes a row is sent with are still checked apart. A file version's base is the newer version, which a walk in rid order has not reached yet, so every version went out whole: a 9 MB text per version of sqlite3.c. A content base the walk has not reached is now forwardable when the store's classification of the cone keeps it (SC-6.2-2 bars only a base outside the keep set). check-in: 9a2938b626 user: [email protected] tags: feat/horizon-cones, trunk | |

perf(manifest): stop re-testing every file of a waiting check-in
A clone's receive linker tested a deferred check-in's every F card again each time one blob it waited on arrived, and each time a manifest it was a delta of arrived, and its waiter index (8192 entries) filled after a few check-ins of a large tree. A sparse store's out-of-cone files never arrive, so a cone or content clone of fossil-scm.org's repository spent its first round, past 20 minutes, in availability queries. A sparse store now waits on no file: it holds what its cone keeps, and SparseCheckinReady judges its completeness. A waiter strikes each arrival from its wait set and is examined again only once the set is empty, and a check-in already waiting is not re-examined when a delta source arrives under it. check-in: 09b62091ec user: [email protected] tags: feat/horizon-cones, trunk | |
