From: SZEDER Gábor <szeder.dev@xxxxxxxxx> The final value of the counter of the "Scanning merged commits" progress line is always one less than its expected total, e.g.: Scanning merged commits: 83% (5/6), done. This happens because while iterating over an array the loop variable is passed to display_progress() as-is, but while C arrays (and thus the loop variable) start at 0 and end at N-1, the progress counter must end at N. Fix this by passing 'i + 1' to display_progress(), like most other callsites do. There's an RFC series to add a GIT_TEST_CHECK_PROGRESS=1 mode[1] which catches this issue in the 'fetch.writeCommitGraph' and 'fetch.writeCommitGraph with submodules' tests in 't5510-fetch.sh'. The GIT_TEST_CHECK_PROGRESS=1 mode is not part of this series, but future changes to progress.c may add it or similar assertions to catch this and similar bugs elsewhere. 1. https://lore.kernel.org/git/20210620200303.2328957-1-szeder.dev@xxxxxxxxx/ Signed-off-by: SZEDER Gábor <szeder.dev@xxxxxxxxx> Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@xxxxxxxxx> --- commit-graph.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/commit-graph.c b/commit-graph.c index 3860a0d8477..9d18c1d87d9 100644 --- a/commit-graph.c +++ b/commit-graph.c @@ -2096,7 +2096,7 @@ static void sort_and_scan_merged_commits(struct write_commit_graph_context *ctx) ctx->num_extra_edges = 0; for (i = 0; i < ctx->commits.nr; i++) { - display_progress(ctx->progress, i); + display_progress(ctx->progress, i + 1); if (i && oideq(&ctx->commits.list[i - 1]->object.oid, &ctx->commits.list[i]->object.oid)) { -- 2.33.0.632.g78310755cd0
