  "message": "list-objects: handle NULL function pointers\n\nIf a caller to traverse_commit_list() specifies the options for the\n--objects flag but does not specify a show_object function pointer, the\nresult is a segfault. This is currently visible by running \u0027git bundle\ncreate --objects HEAD\u0027.\n\nWe could fix this problem by supplying a no-op callback in\nbuiltin/bundle.c, but that only solves the problem for one builtin,\nleaving this segfault open for other callers.\n\nReplace all callers of the show_commit and show_object function pointers\nin list-objects.c to call helper functions show_commit() and\nshow_object() which check that the given context has non-NULL functions\nbefore passing the necessary data. One extra benefit is that it reduces\nduplication due to passing ctx-\u003eshow_data to every caller.\n\nTest that this segfault no longer occurs for \u0027git bundle\u0027.\n\nCo-authored-by: Derrick Stolee \u003cderrickstolee@github.com\u003e\nSigned-off-by: Ævar Arnfjörð Bjarmason \u003cavarab@gmail.com\u003e\nSigned-off-by: Derrick Stolee \u003cderrickstolee@github.com\u003e\nSigned-off-by: Junio C Hamano \u003cgitster@pobox.com\u003e\n",
