From 08065f02945e4304226202268a02823e5ba66582 Mon Sep 17 00:00:00 2001 From: Stefan Haller Date: Fri, 30 Oct 2026 21:10:31 +0100 Subject: [PATCH] Load the commits down to the current bisect commit The commits view loads the first 300 commits only. If the range to bisect is longer than about 600 commits, the commit that git wants the user to test is further down than that, so it isn't shown, and we can't select it. While bisecting, count the commits in the log above the current commit, and load that many more than usual.
