As mentioned in #10698, we have too many `ShellError` variants, with
some even overlapping in meaning. This PR simplifies and improves I/O
error handling by restructuring `ShellError` related to I/O issues.
Previously, `ShellError::IOError` only contained a message string,
making it convenient but overly generic. It was widely used without
providing spans (#4323).
This PR introduces a new `ShellError::Io` variant that consolidates
multiple I/O-related errors (except for `ShellError::NetworkFailure`,
which remains distinct for now). The new `ShellError::Io` variant
replaces the following:
- `FileNotFound`
- `FileNotFoundCustom`
- `IOInterrupted`
- `IOError`
- `IOErrorSpanned`
- `NotADirectory`
- `DirectoryNotFound`
- `MoveNotPossible`
- `CreateNotPossible`
- `ChangeAccessTimeNotPossible`
- `ChangeModifiedTimeNotPossible`
- `RemoveNotPossible`
- `ReadingFile`
## The `IoError`
`IoError` includes the following fields:
1. **`kind`**: Extends `std::io::ErrorKind` to specify the type of I/O
error without needing new `ShellError` variants. This aligns with the
approach used in `std::io::Error`. This adds a second dimension to error
reporting by combining the `kind` field with `ShellError` variants,
making it easier to describe errors in more detail. As proposed by
@kubouch in [#design-discussion on
Discord](https://discord.com/channels/601130461678272522/615329862395101194/1323699197165178930),
this helps reduce the number of `ShellError` variants. In the error
report, the `kind` field is displayed as the "source" of the error,
e.g., "I/O error," followed by the specific kind of I/O error.
2. **`span`**: A non-optional field to encourage providing spans for
better error reporting (#4323).
3. **`path`**: Optional `PathBuf` to give context about the file or
directory involved in the error (#7695). If provided, it’s shown as a
help entry in error reports.
4. **`additional_context`**: Allows adding custom messages when the
span, kind, and path are insufficient. This is rendered in the error
report at the labeled span.
5. **`location`**: Sometimes, I/O errors occur in the engine itself and
are not caused directly by user input. In such cases, if we don’t have a
span and must set it to `Span::unknown()`, we need another way to
reference the error. For this, the `location` field uses the new
`Location` struct, which records the Rust file and line number where the
error occurred. This ensures that we at least know the Rust code
location that failed, helping with debugging. To make this work, a new
`location!` macro was added, which retrieves `file!`, `line!`, and
`column!` values accurately. If `Location::new` is used directly, it
issues a warning to remind developers to use the macro instead, ensuring
consistent and correct usage.
### Constructor Behavior
`IoError` provides five constructor methods:
- `new` and `new_with_additional_context`: Used for errors caused by
user input and require a valid (non-unknown) span to ensure precise
error reporting.
- `new_internal` and `new_internal_with_path`: Used for internal errors
where a span is not available. These methods require additional context
and the `Location` struct to pinpoint the source of the error in the
engine code.
- `factory`: Returns a closure that maps an `std::io::Error` to an
`IoError`. This is useful for handling multiple I/O errors that share
the same span and path, streamlining error handling in such cases.
## New Report Look
This is simulation how the I/O errors look like (the `open crates` is
simulated to show how internal errors are referenced now):

## `Span::test_data()`
To enable better testing, `Span::test_data()` now returns a value
distinct from `Span::unknown()`. Both `Span::test_data()` and
`Span::unknown()` refer to invalid source code, but having a separate
value for test data helps identify issues during testing while keeping
spans unique.
## Cursed Sneaky Error Transfers
I removed the conversions between `std::io::Error` and `ShellError` as
they often removed important information and were used too broadly to
handle I/O errors. This also removed the problematic implementation
found here:
7ea4895513/crates/nu-protocol/src/errors/shell_error.rs (L1534-L1583)
which hid some downcasting from I/O errors and made it hard to trace
where `ShellError` was converted into `std::io::Error`. To address this,
I introduced a new struct called `ShellErrorBridge`, which explicitly
defines this transfer behavior. With `ShellErrorBridge`, we can now
easily grep the codebase to locate and manage such conversions.
## Miscellaneous
- Removed the OS error added in #14640, as it’s no longer needed.
- Improved error messages in `glob_from` (#14679).
- Trying to open a directory with `open` caused a permissions denied
error (it's just what the OS provides). I added a `is_dir` check to
provide a better error in that case.
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
- Error outputs now include more detailed information and are formatted
differently, including updated error codes.
- The structure of `ShellError` has changed, requiring plugin authors
and embedders to update their implementations.
# Tests + Formatting

I updated tests to account for the new I/O error structure and
formatting changes.

# Description
This PR removes the old `touch` command in favor of the uutils/coreutils
implementation of `touch`, which we integrated in 0.101 (#11817).
It turns out that in `utouch`, the `--no-deref`/`-s` wasn't working, and
the issue had gone undetected because I accidentally made the test for
that use `touch` rather than `utouch`. This has been fixed now.
# User-Facing Changes
Our old `touch` command didn't have anything that the new uutils-based
command doesn't, and the uutils-based command actually has a little more
functionality. So nothing using `touch` should break.
Scripts using `utouch` will have to use `touch` now, but given that
`utouch` has been around for less than 2 months, I assume people haven't
really been using it.
# Tests + Formatting
The utouch tests seem to have everything from the old touch tests, so I
deleted the old touch tests.
# After Submitting
This will need to be mentioned in the release notes.
# Description
These changes resolve#13623 where globs are not handled by `utouch`.
# User-Facing Changes
- Glob patterns passed to `utouch` will be resolved to all individual
files that match the pattern. For example, running `utouch *.txt` in a
directory that already has `file1.txt` and `file2.txt` is the same thing
as running `utouch file1.txt file2.txt`. All flags such as `-a`, `-m`
and `-c` will be respected.
- If a glob pattern is provided to `utouch` and doesn't match any files,
a file will be created with the literal name of the glob pattern. This
only applies to Linux/MacOS because Windows forbids creating file names
with restricted characters (see [naming a file
docs](https://learn.microsoft.com/en-us/windows/win32/fileio/naming-a-file))

This PR adds a `utouch` command that uses the `touch` command from
https://github.com/uutils/coreutils. Eventually, `utouch` may be able to
replace `touch`.
The conflicts in Cargo.lock and Cargo.toml are because I'm using the
uutils/coreutils main rather than the latest release, since the changes
that expose `uu_touch`'s internal functionality aren't available in the
latest release.
