This commit aim to correct #2645.
The origin of the problem was that `handle_obsolete` was not looking for
named signals but only for numbers preceded by '-'. I have made a few
changes:
- Change `handle_obsolete` to use `signal_by_name_or_value` to parse the
possible signal.
- Since now the signal is already parsed return an `Option<usize>`
instead of `Option<&str>` to parse later.
- Change the way to decide the pid to use from a `match` to a `if`
because the tested element are actually not the same for each branch.
- Parse the signal from the `-s` argument outside of `kill` function for
consistency with the "obsolete" signal case.
- Again for consistency, parse the pids outside the `kill` function.
* chown: support '.' as 'user.group' separator (like ':')
It also manages the case:
user.name:group (valid too)
Should fix:
gnu/tests/chown/separator.sh
* Fixed some documentation of display_item_long that was missed in #2623
* Implemented coloring of `ls -l` symlink targets( after the arrow `->`).
* Documented display_file_name to some extent.
* Ran rustfmt as part of mitigating CI chain errors.
* Removed unused variables and code in test_ls_long_format as per #2623
specifically, as per
https://github.com/uutils/coreutils/pull/2623#pullrequestreview-742386707
* Added a thorough test for `ls -laR --color` symlink coloring implemented in this branch.
* renamed test files and dirs to shorter names and ran rustfmt.
* Changed the order with which files are expected to match the change in their name.
* Bettered some comments.
* Removed needless borrow. Fixed that one clippy warning.
* Moved the cfg not windows up to the function level
because this function is meant to only run in non-windows OS (with
groups and unames).
Fixes the unused variable warning in CI.
Part of the code was transliterated from GNU's implementation in C,
and used flags to store settings. Instead, we can use enums to avoid
magic values or binary operations to extract flags.
- prevent duplicate errors from both us and `walkdir` by instructing `walkdir'
to skip directories we failed to read metadata for.
- don't directly display `walkdir`'s errors, but format them ourselves to
match gnu's format
This way later code can assume `src` and `dest` to be the actual paths
of source and destination, and do not have to constantly check
`options.dereference`.
This requires moving the error context calculation to the beginning as
well, since later steps no longer operate with the same file paths as
supplied by the user.
Fix a mix-up between ownership and mode. The latter (mode / file permissions)
can also be set on windows (which however only affects the read-only flag),
while there doesn't seem to be a straight-forward way to change file ownership
on windows.
Copy the acl as well when copying the mode. This is a non-default feature and can be
enabled with --features feat_acl, because it doesn't seem to work on CI.
It is only available for unix so far.
Copy the SELinux context if possible.
Makes the -o auto option construct a format at initialization, rather
than try to handle it as a special case when printing lines. Fixes bugs
when combined with -e, especially when combined with -a.
