"SEEN" seems perfectly fine. For some reason I thought that there might be issues using SEEN (1u<<0) but trying it locally does not seem to be a problem. I think I've just been bit by how revision.c uses it a bit too often. The use here is independent enough to not cause problems. >> +static int num_commits_not_in_graph = 0; >> +static int limit_commits_not_in_graph = 100; >> + >> +static int dfs_on_ref(const char *refname, >> + const struct object_id *oid, int flags, >> + void *cb_data) >> +{ > > [snip] > >> +static int should_write_commit_graph(void) >> +{ >> + int result; >> + >> + git_config_get_int("maintenance.commit-graph.auto", >> + &limit_commits_not_in_graph); >> + >> + if (!limit_commits_not_in_graph) >> + return 0; >> + if (limit_commits_not_in_graph < 0) >> + return 1; >> + >> + result = for_each_ref(dfs_on_ref, NULL); > > I don't like introducing the mutable global num_commits_not_in_graph > especially when there seems to be at least one easy alternative (e.g. > putting it in cb_data) but I know that this is a pattern than existing > code. I should have done this right in the first place. Thanks for catching it. -Stolee
