Some tests failed when run using Docker because they assumed the
user would never be root. This is more of a band-aid solution.
An actual fix would be to test see if something like these tests
were to succeed when the user is root.
ln had a bunch of problems:
1. `ln -s target` didn't work (2nd form in help).
2. `ln -t tmp` wasn't an error. We should check if files are
empty first.
3. `ln -s file dir` didn't create dir/file.
4. `ln -s -T file dir` was removing `dir`.
5. Test cases for 4 say this is for compatibility with GNU
coreutils but I couldn't find this feature.
Path::is_dir follows symlinks so it returns true for symlinks
to directories. Use symlink_metadata instead so you can remove
symlinks to directories without -r flag.
Currently, mkdir always succeeds for existing files and it
even modifies their mode. With this change, only mkdir -p for
existing directories will be allowed.
Make at_line_start persist between printing each file. This fixes an
issue when numbering lines in the output and one of the input files
does not have a trailing newline.
- adds conditional supports for unix domain sockets
- adds unix domain socket test
- adds Results to functions, removing unwraps
- uutils `cat` used to panic on broken stdout pipes (e.g. `cat
/dev/zero | head -c1`). this is fixed in this PR
- updated to exit 0 on success, and 1 if an error occurs.
- adds docstrings
- adds an error log on printing a directory
- adds categorization of other filetypes for extensible
differentiation of behaviors
- adds OutputOptions struct to replace params for extensibility
- adds correct status code on exit
Fixes#1017.
test_mkdir_dup_dir asserted that creating an existing directory is an
error, but that's not how GNU coreutils behaves. This has been reported
in #121, but wasn't fixed (only the `-p` case was).
