The test code added in9c4d6c0297
(cache-tree: Write updated cache-tree after commit, 2014-07-13) used "ls-files" in lieu of "ls-tree" because it wanted to test the data in the index, since this test is testing the cache-tree extension. Change the test to instead use "ls-tree" for traversal, and then explicitly check how HEAD differs from the index. This is more easily understood, and less fragile as numerous past bug fixes[1][2][3] to the old code we're replacing demonstrate. As an aside this would be a bit easier if empty pathspecs hadn't been made an error ind426430e6e
(pathspec: warn on empty strings as pathspec, 2016-06-22) and9e4e8a64c2
(pathspec: die on empty strings as pathspec, 2017-06-06). If that was still allowed this code could be simplified slightly: diff --git a/t/t0090-cache-tree.sh b/t/t0090-cache-tree.sh index 9bf66c9e68..0b02881f55 100755 --- a/t/t0090-cache-tree.sh +++ b/t/t0090-cache-tree.sh @@ -18,19 +18,18 @@ cmp_cache_tree () { # test-tool dump-cache-tree already verifies that all existing data is # correct. generate_expected_cache_tree () { - pathspec="$1" && - dir="$2${2:+/}" && + pathspec="$1${1:+/}" && git ls-tree --name-only HEAD -- "$pathspec" >files && git ls-tree --name-only -d HEAD -- "$pathspec" >subtrees && - printf "SHA %s (%d entries, %d subtrees)\n" "$dir" $(wc -l <files) $(wc -l <subtrees) && + printf "SHA %s (%d entries, %d subtrees)\n" "$pathspec" $(wc -l <files) $(wc -l <subtrees) && while read subtree do - generate_expected_cache_tree "$pathspec/$subtree/" "$subtree" || return 1 + generate_expected_cache_tree "$subtree" || return 1 done <subtrees } test_cache_tree () { - generate_expected_cache_tree "." >expect && + generate_expected_cache_tree >expect && cmp_cache_tree expect && rm expect actual files subtrees && git status --porcelain -- ':!status' ':!expected.status' >status && 1.c8db708d5d
