* Move the user and group resolution to the behavior decoding instead of
re-running on every file/directory creation. Simplifies code.
* Update error output to match GNU coreutils.
* Add tests to verify invalid owner and group.
* Re-factor the copy function chown into a function that can be re-used.
* Fix bug where the group overwrote the user.
* Add chown compatibility to follow GNU coreutils.
* Reduce two chown calls to a single syscall only when needed.
* Fixes#4361
* install: fix installing one file when using -Dt options
* install: fix installing multiple files with -Dt
Code was missing the logic to create the target dir when multiple files
should be copied and target dir is given by -t option.
This simplifies the copy logic also when only one file should be copied
to the target dir.
* install: fix verbose output when using -D
Also adds a unit test to verify the same behaviour as the gnu tools.
* install: add more testcases for create leading dir
Tests various combinations of "-D" with and w/o "-t" when installing
either a single file or multiple files into a non existing directory.
install -D file1 file2 (-t) not_existing_dir
install -D file1 (-t) not_existing_dir/
Also fixes file formatting, spelling and adds some more test asserts.
* install: fix error for nonex. dir path ending on /
The install command failed with a different error message than the
original GNU install tool. Checking for a trailing slash fixes this.
Only works on unix though.
* install: add windows support when checking for '/'
* install.rs: fix spelling
* install.rs: add more tests regarding omitting dir
This increases the CI test coverage and also checks for more corner
cases to ensure uu_install is compliant with GNU's original.
export C=coreutils/target/debug/
rm -rf dir1 no-dir2 dir3 file
mkdir -p dir1 dir3
touch file
${C}install dir1/file1 dir1/.. no-dir2
${C}install dir1/file1 dir1/.. dir3
${C}install dir1/.. dir3
* install: improve test_install_missing_arguments
Also check that install returns the correct error messages, when only a
target directory is given via -t and that is is not created (-D option).
* install: rework the checks for missing file args
This ensures correct (GNU install like) behavior. Tests from the last
commit will pass now.
