I'm bending over backwards here to avoid a SHA-1 dependency. See [1] for an earlier and simpler version that hardcoded SHA-1s. This behavior has been the same for a *long* time, but hasn't been tested for. There's a good post-hoc argument to be made for copying over unknown things, e.g. I'd like a git version that doesn't know about the commit-graph to copy it under "clone --local" so a newer git version can make use of it. In follow-up commits we'll look at changing some of this behavior, but for now, let's just assert it as-is so we'll notice what we'll change later. 1. https://public-inbox.org/git/20190226002625.13022-5-avarab@gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason [matheus.bernardino: improved and split tests in more than one patch] Helped-by: Matheus Tavares Signed-off-by: Matheus Tavares --- t/t5604-clone-reference.sh | 111 +++++++++++++++++++++++++++++++++++++ 1 file changed, 111 insertions(+) diff --git a/t/t5604-clone-reference.sh b/t/t5604-clone-reference.sh index 4320082b1b..207650cb95 100755 --- a/t/t5604-clone-reference.sh +++ b/t/t5604-clone-reference.sh @@ -221,4 +221,115 @@ test_expect_success 'clone, dissociate from alternates' ' ( cd C && git fsck ) ' +test_expect_success 'setup repo with garbage in objects/*' ' + git init S && + ( + cd S && + test_commit A && + + cd .git/objects && + >.some-hidden-file && + >some-file && + mkdir .some-hidden-dir && + >.some-hidden-dir/some-file && + >.some-hidden-dir/.some-dot-file && + mkdir some-dir && + >some-dir/some-file && + >some-dir/.some-dot-file + ) +' + +test_expect_success 'clone a repo with garbage in objects/*' ' + for option in --local --no-hardlinks --shared --dissociate + do + git clone $option S S$option || return 1 && + git -C S$option fsck || return 1 + done && + find S-* -name "*some*" | sort >actual && + cat >expected <<-EOF && + S--dissociate/.git/objects/.some-hidden-file + S--dissociate/.git/objects/some-dir + S--dissociate/.git/objects/some-dir/.some-dot-file + S--dissociate/.git/objects/some-dir/some-file + S--dissociate/.git/objects/some-file + S--local/.git/objects/.some-hidden-file + S--local/.git/objects/some-dir + S--local/.git/objects/some-dir/.some-dot-file + S--local/.git/objects/some-dir/some-file + S--local/.git/objects/some-file + S--no-hardlinks/.git/objects/.some-hidden-file + S--no-hardlinks/.git/objects/some-dir + S--no-hardlinks/.git/objects/some-dir/.some-dot-file + S--no-hardlinks/.git/objects/some-dir/some-file + S--no-hardlinks/.git/objects/some-file + EOF + test_cmp expected actual +' + +test_expect_success SYMLINKS 'setup repo with manually symlinked dirs and unknown files at objects/' ' + git init T && + ( + cd T && + git config gc.auto 0 && + test_commit A && + git gc && + test_commit B && + + cd .git/objects && + mv pack packs && + ln -s packs pack && + find ?? -type d >loose-dirs && + last_loose=$(tail -n 1 loose-dirs) && + rm -f loose-dirs && + mv $last_loose a-loose-dir && + ln -s a-loose-dir $last_loose && + find . -type f | sort >../../../T.objects-files.raw && + echo unknown_content> unknown_file + ) && + git -C T fsck && + git -C T rev-list --all --objects >T.objects +' + + +test_expect_success SYMLINKS 'clone repo with symlinked dirs and unknown files at objects/' ' + for option in --local --no-hardlinks --shared --dissociate + do + git clone $option T T$option || return 1 && + git -C T$option fsck || return 1 && + git -C T$option rev-list --all --objects >T$option.objects && + test_cmp T.objects T$option.objects && + ( + cd T$option/.git/objects && + find . -type f | sort >../../../T$option.objects-files.raw + ) + done && + + for raw in $(ls T*.raw) + do + sed -e "s!/../!/Y/!; s![0-9a-f]\{38,\}!Z!" -e "/commit-graph/d" \ + -e "/multi-pack-index/d" <$raw >$raw.de-sha || return 1 + done && + + cat >expected-files <<-EOF && + ./Y/Z + ./Y/Z + ./a-loose-dir/Z + ./Y/Z + ./info/packs + ./pack/pack-Z.idx + ./pack/pack-Z.pack + ./packs/pack-Z.idx + ./packs/pack-Z.pack + ./unknown_file + EOF + + for option in --local --dissociate --no-hardlinks + do + test_cmp expected-files T$option.objects-files.raw.de-sha || return 1 + done && + + echo ./info/alternates >expected-files && + test_cmp expected-files T--shared.objects-files.raw +' + test_done -- 2.22.0
