All the utilities use the new API I defined in mu recent PR to
redox_users. `su`'s behavior was also fixed.
I also updated Cargo.toml (removing unused deps). This may require
another commit after my first PR is merged in order to appropriately
update Cargo.lock and make sure everything builds.
Details
- Updated dependencies with `redox_users`.
- Migrated all user/group dependent functionality to calls to `redox_users`.
- Added top level documentation to the crate.
- Added a `spawn_shell` function to reuse a bit of code.
- `login`: Handled the case of an invalid login with "Login incorrect" (as in BSD).
- `passwd`: Refactored a bit and used `eprintln!` where possible.
- `su`: Refactored a bit and used `eprintln!` where possible.
- `sudo`: Refactored a bit to simplify logic also used `eprintln!` where possible.
- `whoami`: Refactored a bit and used `eprintln!/println!` where possible.
- Also added myself on the AUTHORS section :).
Details
- The current implementataion the `whoami` utility relies
on a env var to determine the user. With this change we get
the effective user id of the context and lookup that id on
/etc/passwd.
- Added the Redox `libextra` dependency as it has some goodies
for error handling. This will allow to make this crate upto date
with `coreutils` practices.
- Added a new small `arg_parser` crate that was extracted from
`coreutils` as is now commen between `coreutils` and here.
