Telling the user "I don't understand non-hex object names" instead of just "invalid commit object" may be useful. I think it would also make the flow of the function easier to follow. If we were writing from scratch, I'd actually suggest that builtin/commit-graph.c do parse_oid_hex() call as we read lines, and then commit-graph could just be working with an oid_array or oidset, which would reduce overall memory usage. I don't know if that would cause other complications, but it could be worth looking into. > + if (ret || (ctx->check_oids && !result)) { > error(_("invalid commit object id: %s"), > commit_hex->items[i].string); > return -1; We could also take this a step further and just ditch check_oids entirely (under the assumption that nobody really wants it; they just wanted to catch bad names in the first place). -Peff
