  "message": "commit-graph tests: fix unportable \"dd\" invocation\n\nChange an unportable invocation of \"dd\" with count\u003d0, that wanted to\ntruncate the commit-graph file.  In POSIX it is unspecified what\nhappens when count\u003d0 is provided[1]. The NetBSD \"dd\" behavior\ndiffers from GNU (and seemingly other BSDs), which has left this test\nbroken since d2b86fbaa1 (\"commit-graph: fix buffer read-overflow\",\n2019-01-15).\n\nCopying from /dev/null would seek/truncate to seek\u003d$zero_pos and\nstop immediately after that (without being able to copy anything),\nwhich is the right way to truncate the file.\n\n1. http://pubs.opengroup.org/onlinepubs/9699919799/utilities/dd.html\n\nSigned-off-by: Ævar Arnfjörð Bjarmason \u003cavarab@gmail.com\u003e\nHelped-by: SZEDER Gábor \u003cszeder.dev@gmail.com\u003e\nSigned-off-by: Junio C Hamano \u003cgitster@pobox.com\u003e\n",
