  "message": "builtin/repack.c: avoid making cruft packs preferred\n\nWhen doing a `--geometric` repack, we make sure that the preferred pack\n(if writing a MIDX) is the largest pack that we *didn\u0027t* repack. That\nhas the effect of keeping the preferred pack in sync with the pack\ncontaining a majority of the repository\u0027s reachable objects.\n\nBut if the repository happens to double in size, we\u0027ll repack\neverything. Here we don\u0027t specify any `--preferred-pack`, and instead\nlet the MIDX code choose.\n\nIn the past, that worked fine, since there would only be one pack to\nchoose from: the one we just wrote. But it\u0027s no longer necessarily the\ncase that there is one pack to choose from. It\u0027s possible that the\nrepository also has a cruft pack, too.\n\nIf the cruft pack happens to come earlier in lexical order (and has an\nearlier mtime than any non-cruft pack), we\u0027ll pick that pack as\npreferred. This makes it impossible to reuse chunks of the reachable\npack verbatim from pack-objects, so is sub-optimal.\n\nLuckily, this is a somewhat rare circumstance to be in, since we would\nhave to repack the entire repository during a `--geometric` repack, and\nthe cruft pack would have to sort ahead of the pack we just created.\n\nSigned-off-by: Taylor Blau \u003cme@ttaylorr.com\u003e\nSigned-off-by: Junio C Hamano \u003cgitster@pobox.com\u003e\n",
