ZheNing Hu via GitGitGadget <gitgitgadget@gmail.com> 于2024年12月31日周二 10:18写道： > > From: ZheNing Hu <adlternative@gmail.com> > > This commit extends the functionality of `git gc` > by adding a new option, `--expire-to=<dir>`. Previously, > this feature was implemented in `git repack` (see 91badeb), > allowing users to specify a directory where unreachable and > expired cruft packs are stored during garbage collection. > However, users had to run `git repack --cruft --expire-to=<dir>` > followed by `git prune` to achieve similar results within `git gc`. > > By introducing `--expire-to=<dir>` directly into `git gc`, > we simplify the process for users who wish to manage their > repository's cleanup more efficiently. This change involves > passing the `--expire-to=<dir>` parameter through to `git repack`, > making it easier for users to set up a backup location for cruft > packs that will be pruned. > > Signed-off-by: ZheNing Hu <adlternative@gmail.com> > --- > Documentation/git-gc.txt | 6 ++++++ > builtin/gc.c | 6 +++++- > t/t6500-gc.sh | 6 ++++++ > 3 files changed, 17 insertions(+), 1 deletion(-) > > diff --git a/Documentation/git-gc.txt b/Documentation/git-gc.txt > index 370e22faaeb..b4c0cf02972 100644 > --- a/Documentation/git-gc.txt > +++ b/Documentation/git-gc.txt > @@ -69,6 +69,12 @@ be performed as well. > the `--max-cruft-size` option of linkgit:git-repack[1] for > more. > > +--expire-to=<dir>:: > + When packing unreachable objects into a cruft pack, write a cruft > + pack containing pruned objects (if any) to the directory `<dir>`. > + See the `--expire-to` option of linkgit:git-repack[1] for > + more. > + > --prune=<date>:: > Prune loose objects older than date (default is 2 weeks ago, > overridable by the config variable `gc.pruneExpire`). > diff --git a/builtin/gc.c b/builtin/gc.c > index d52735354c9..77904694c9f 100644 > --- a/builtin/gc.c > +++ b/builtin/gc.c > @@ -136,6 +136,7 @@ struct gc_config { > char *prune_worktrees_expire; > char *repack_filter; > char *repack_filter_to; > + char *repack_expire_to; > unsigned long big_pack_threshold; > unsigned long max_delta_cache_size; > }; > @@ -441,6 +442,8 @@ static void add_repack_all_option(struct gc_config *cfg, > if (cfg->max_cruft_size) > strvec_pushf(&repack, "--max-cruft-size=%lu", > cfg->max_cruft_size); > + if (cfg->repack_expire_to) > + strvec_pushf(&repack, "--expire-to=%s", cfg->repack_expire_to); > } else { > strvec_push(&repack, "-A"); > if (cfg->prune_expire) > @@ -675,7 +678,6 @@ struct repository *repo UNUSED) > const char *prune_expire_sentinel = "sentinel"; > const char *prune_expire_arg = prune_expire_sentinel; > int ret; > - > struct option builtin_gc_options[] = { > OPT__QUIET(&quiet, N_("suppress progress reporting")), > { OPTION_STRING, 0, "prune", &prune_expire_arg, N_("date"), > @@ -694,6 +696,8 @@ struct repository *repo UNUSED) > PARSE_OPT_NOCOMPLETE), > OPT_BOOL(0, "keep-largest-pack", &keep_largest_pack, > N_("repack all other packs except the largest pack")), > + OPT_STRING(0, "expire-to", &cfg.repack_expire_to, N_("dir"), > + N_("pack prefix to store a pack containing pruned objects")), > OPT_END() > }; > > diff --git a/t/t6500-gc.sh b/t/t6500-gc.sh > index ee074b99b70..d4b0653a9b7 100755 > --- a/t/t6500-gc.sh > +++ b/t/t6500-gc.sh > @@ -339,6 +339,12 @@ test_expect_success 'gc.maxCruftSize sets appropriate repack options' ' > test_subcommand $cruft_max_size_opts --max-cruft-size=3145728 <trace2.txt > ' > > +test_expect_success '--expire-to sets appropriate repack options' ' > + mkdir expired && > + GIT_TRACE2_EVENT=$(pwd)/trace2.txt git -C cruft--max-size gc --cruft --expire-to=./expired/pack && > + test_subcommand $cruft_max_size_opts --expire-to=./expired/pack <trace2.txt > +' > + > run_and_wait_for_gc () { > # We read stdout from gc for the side effect of waiting until the > # background gc process exits, closing its fd 9.
