  "message": "commit-graph.c: no lazy fetch in lookup_commit_in_graph()\n\nThe commit-graph is used to opportunistically optimize accesses to\ncertain pieces of information on commit objects, and\nlookup_commit_in_graph() tries to say \"no\" when the requested commit\ndoes not locally exist by returning NULL, in which case the caller\ncan ask for (which may result in on-demand fetching from a promisor\nremote) and parse the commit object itself.\n\nHowever, it uses a wrong helper, repo_has_object_file(), to do so.\nThis helper not only checks if an object is mmediately available in\nthe local object store, but also tries to fetch from a promisor remote.\nBut the fetch machinery calls lookup_commit_in_graph(), thus causing an\ninfinite loop.\n\nWe should make lookup_commit_in_graph() expect that a commit given to it\ncan be legitimately missing from the local object store, by using the\nhas_object_file() helper instead.\n\nSigned-off-by: Han Xin \u003chanxin.hx@bytedance.com\u003e\nSigned-off-by: Junio C Hamano \u003cgitster@pobox.com\u003e\n",
