This makes uu_tail pass the "gnu/tests/tail-2/descriptor-vs-rename" test.
* add tests for descriptor-vs-rename (with/without verbose)
* fix some minor error messages
* Change data structure from Vec to HashMap in order to better
keep track of files while watching them with `--follow=name`.
E.g. file paths that were removed while watching them and exit
if no files are remaining, etc.
* Move all logic related to file handling into a FileHandling trait
* Simplify handling of the verbose flag.
For the CICD on macOS, this fixes:
```
---- common::util::tests::test_check_coreutil_version stdout ----
---- common::util::tests::test_expected_result stdout ----
thread 'common::util::tests::test_expected_result' panicked at
'byte index 4 is out of bounds of `9.0`', tests/common/util.rs:1172:41
```
Replace two loops that print leading and trailing 0s when printing a
number in fixed-width mode with a single call to `write!()` with the
appropriate formatting parameters.
Ensure that the `print_seq_integers()` function is called when the first
number and the increment are integers, regardless of the type of the
last value specified.
Change the way `seq` computes the number of digits needed to print a
number so that it works for inputs given in scientific notation.
Specifically, this commit parses the input string to determine whether
it is an integer, a float in decimal notation, or a float in scientific
notation, and then computes the number of integral digits and the number
of fractional digits based on that. This also supports floating point
negative zero, expressed in both decimal and scientific notation.
This fixes an issue on macOS/bsd where multiple calls
to `host_name_for` each added a prefix 'g'.
The issue led to some tests being skipped because `util_name` was
renamed to e.g. "ggid" instead of "gid".
This makes it no longer possible to pass multiple filenames, but every
other implementation I tried (GNU, busybox, FreeBSD, sbase) also
forbids that so I think it's for the best.
* chown: support '.' as 'user.group' separator (like ':')
It also manages the case:
user.name:group (valid too)
Should fix:
gnu/tests/chown/separator.sh
