repocache: a hit rewrites a stale or missing image (zit#180)
A cache whose image is absent or at an old layout replayed the record body on every fast_read open, since only a miss stored. The hit now serializes the image from the view it just built and stores it, so the fallback is paid once. check-in: 98c5d6c61a user: dmestas tags: trunk | |

timeline: read the image, not a full derive (zit#181)
The image has carried adjacency since layout 2 and comment/login since layout 6, so every default row renders from the zero-parse path; only full/-v/-p still read manifests. 60 ms to 8 ms on a 22k check-in store, output byte-identical across formats. check-in: 18ffce5678 user: dmestas tags: trunk | |

grep: read manifests only where the record says PATH changed (zit#178)
One record scan, as annotate, instead of a manifest per check-in: 20,937 reads to 272 on VERSION, 19s to 0.4s. Each version is reported once under its oldest introducer, matching fossil grep's list byte for byte. check-in: 6be0341149 user: dmestas tags: trunk | |
