test_description='git ls-tree test.
This test runs git ls-tree with the following in a tree.
path0 - a file
path1 - a symlink
path2/foo - a file in a directory
path2/bazbo - a symlink in a directory
path2/baz/b - a file in a directory in a directory
The new path restriction code should do the right thing for path2 and
path2/baz. Also path0/ should snow nothing.

[PATCH] Rewrite ls-tree to behave more like "/bin/ls -a" This is a complete rewrite of ls-tree to make it behave more like what "/bin/ls -a" does in the current working directory. Namely, the changes are: - Unlike the old ls-tree behaviour that used paths arguments to restrict output (not that it worked as intended---as pointed out in the mailing list discussion, it was quite incoherent), this rewrite uses paths arguments to specify what to show. - Without arguments, it implicitly uses the root level as its sole argument ("/bin/ls -a" behaves as if "." is given without argument). - Without -r (recursive) flag, it shows the named blob (either file or symlink), or the named tree and its immediate children. - With -r flag, it shows the named path, and recursively descends into it if it is a tree. - With -d flag, it shows the named path and does not show its children even if the path is a tree, nor descends into it recursively. This is still request-for-comments patch. There is no mailing list consensus that this proposed new behaviour is a good one. The patch to t/t3100-ls-tree-restrict.sh illustrates user-visible behaviour changes. Namely: * "git-ls-tree $tree path1 path0" lists path1 first and then path0. It used to use paths as an output restrictor and showed output in cache entry order (i.e. path0 first and then path1) regardless of the order of paths arguments. * "git-ls-tree $tree path2" lists path2 and its immediate children but having explicit paths argument does not imply recursive behaviour anymore, hence paths/baz is shown but not paths/baz/b.
