du --time formats a file's timestamp according to the local timezone,
but the test implicitly assumed UTC. This caused it to fail when
running locally in my UTC+1 machine.
$ cargo test --features "du touch" --no-default-features
Failure: https://gist.github.com/eggpi/651e01559b7c59e9457c1b22fe4c0c19
The `test_du_bytes` testcase for the `du --bytes` command is written to perform
a dynamic comparison on linux hosts, i.e. it compares the output of the command
to that of the hosts `du` from the GNU coreutils.
Previously the test was written such that it would *first* perform the dynamic
comparison, and *after that* continue to a static comparison which may fail for
specific hosts that have a filesystem different from what the test expects.
This patch excludes linux hosts from the static comparison to ensure the test
performs only the dynamic comparison.
`LANGUAGE=C` is not enough, `LC_ALL=C` is needed as the environment
variable that overrides all the other localization settings.
e.g.
```bash
$ LANGUAGE=C id foobar
id: ‘foobar’: no such user
$ LC_ALL=C id foobar
id: 'foobar': no such user
```
* replace `LANGUAGE` with `LC_ALL` as environment variable in the tests
* fix the the date string of affected uutils
* replace `‘` and `’` with `'`
* du error output should match GNU
* Created a new error macro which allows the customization of the
"error:" string part
* Match the du output based on the type of error encountered. Can extend
to handling other errors I guess.
* Rustfmt updates
* Added non-windows test for du no permission output
* Replace outdated time 0.1 dependancy with latest version of chrono
I also noticed that times are being miscalculated on linux, so I fixed that.
* Add time test for issue #2042
* Cleanup use declarations
* Tie time test to `touch` feature
- if we compile with the right OS feature flag then we should have it,
even on Windows
refactor `is_wsl` to `is_wsl_1` and `is_wsl_2`
On my tests with wsl2 ubuntu2004 all tests pass without special cases
I moved wsl detection into uucore so that it can be shared instead of duplicated
I moved `parse_mode` into uucode as it seemed to fit there better and anyway requires libc feature
