Merge branch 'wip/merge-pivot' into feat/horizon-cones
Merge bases chosen as fossil's pivot_find chooses them: the most recent common ancestor by check-in time, with the check-out's pending merges as further secondaries, in place of a bidirectional breadth-first search that picked a different base on criss-cross and skewed histories. Checked against fossil 2.28 on 114 queries and a byte-for-byte merge. check-in: 97e188b6ef user: [email protected] tags: feat/horizon-cones, trunk | |

fix(merge): read the pivot seed's mtime as a number under every driver
The ncruces driver reads event.mtime, declared DATETIME, as a time.Time, so the pivot search failed to scan its seed under -tags test_ncruces. coalesce() drops the declared type, as the parent query's already did. check-in: 89c6ae4aa6 user: [email protected] tags: feat/horizon-cones, trunk | |

test(conformance): check merge bases against fossil merge-base
The merge base is now fossil's pivot, so check it against fossil(1) on every run rather than against an expectation written once. Scripted graphs, loaded into both implementations, cover a skewed criss-cross (the newest common ancestor two edges away, not the one an edge away), a criss-cross at equal times in both load orders (the higher rid wins the tie), merges of merges and a query with two secondaries, and --ignore-merges. A merge of p into a checkout of s in the skewed graph writes the same bytes as fossil's merge and differs from a merge against the breadth-first base. TestMergeBaseFossilOracle builds six seeded random graphs of sixteen check-ins, with equal times and children older than their parents, and compares 114 merge-base questions, both directions, with and without --ignore-merges and with two secondaries, against fossil merge-base. check-in: 944b44faf6 user: [email protected] tags: feat/horizon-cones, trunk | |
