This change resolves issues with exponent calculation and usage,
ensuring more accurate formatting:
- Exponent for negative values can differ from 0
- Switching to decimal mode now follows the P > X ≥ −4 rule
Improve the error message produced by `seq` when given invalid format
specifiers for the `-f` option. Before this commit:
$ seq -f "%" 1
seq: %: invalid conversion specification
$ seq -f "%g%" 1
seq: %: invalid conversion specification
After this commit:
$ seq -f "%" 1
seq: format '%' ends in %
$ seq -f "%g%" 1
seq: format '%g%' has too many % directives
This matches the behavior of GNU `seq`.
This adds the `os_str_as_bytes_lossy` function, for when we want infallible
conversion across platforms, and improves the doc comments of similar functions
to be more accurate and better formatted.
The code above this line handles the case if `res` is
larger than `ngroups`, but `res < ngroups` is also a possibility,
which this line attempts to address but actually does not.
The original code resizes to `ngroups` which is a no-op (given
that `groups` is already `ngroups` size). The correct target for
re-sizing the `groups` is the result from the last `getgroups`,
i.e., `res`.
Splice is a Linux-specific syscall that allows direct data copying from
one file descriptor to another without user-space buffer. As of now, this
is used by `cp`, `cat`, and `install` when compiled for Linux and Android.
This exposes the non-UTF-8 functionality to callers. Support in `argument`,
`spec`, and `wc` are implemented, as their usage is simple. A wrapper only
returning valid unicode is used in `ls`, since proper handling of OsStrings
there is more involved (outputs that escape non-unicode work now though).
- Rename the function to emphasize its goal
- Do not pass the filename anymore, as it is only used to create an error, that may be done in the scope calling the function
- Change the return type to Option, as the error is made in the outer scope
- Don't try to decode the base64 string as UTF8 string. This most oftenly fails and is wrong.
- Get rid of the `bytes_to_hex` function, as it provides the same functionality as `hex::encode`
