From c08645b353514fe14dbd62cf52afd49d0e88146b Mon Sep 17 00:00:00 2001 From: Taylor Blau Date: Mon, 20 Mar 2023 11:26:52 +0000 Subject: commit-graph: introduce `ensure_generations_valid()` Use the just-introduced compute_reachable_generation_numbers_1() to implement a function which dynamically computes topological levels (or corrected commit dates) for out-of-graph commits. This will be useful for the ahead-behind algorithm we are about to introduce, which needs accurate topological levels on _all_ commits reachable from the tips in order to avoid over-counting.
