Allow tables and records as input to math commands (#11496)
# Description
The math functions `avg`, `max`, `median`, `min`, `product`, `stddev`,
`sum` and `variance` all takes a list as input and return a number.
<https://github.com/nushell/nushell/blob/main/crates/nu-command/src/math/utils.rs>
contains code that makes these functions work for tables (by running the
function on each column), but this functionality has not been accessible
because the input types are too strict. This PR remedies this.

The functions should also work on records, since a record is basically a
one-row table.

Most of these functions also make sense for durations and file sizes,
except `product` of course. There's an implementation issue with
`stddev` and `variance` for durations and file sizes, but they could in
principle support it.

# User-Facing Changes
This PR only adds supported types, and doesn't remove any, so there
should be no breaking changes.

Fix memory consumption of into sqlite (#10232)
# Description

Currently, the `into sqlite` command collects the entire input stream
into a single Value, which soaks up the entire input into memory, before
it ever tries to write anything to the DB. This is very problematic for
large inputs; for example, I tried transforming a multi-gigabyte CSV
file into SQLite, and before I knew what was happening, my system's
memory was completely exhausted, and I had to hard reboot to recover.

This PR fixes this problem by working directly with the pipeline stream,
inserting into the DB as values are read from the stream.

In order to facilitate working with the stream directly, I introduced a
new `Table` struct to store the connection and a few configuration
parameters, as well as to make it easier to lazily create the table on
the first read value.

In addition to the purely functional fixes, a few other changes were
made to the serialization and user facing behavior.

### Serialization

Much of the preexisting code was focused on generating the exact text
needed for a SQL statement. This is unneeded and less safe than using
the `rusqlite` crate's serialization for native Rust types along with
prepared statements.

### User-Facing Changes

Currently, the command is very liberal in the input types it accepts.
The strategy is basically if it is a record, try to follow its structure
and make an analogous SQL row, which is pretty reasonable. However, when
it's not a record, it basically tries to guess what the user wanted and
just makes a single column table and serializes the value into that one
column, whatever type it may be.

This has been changed so that it only accepts records as input. If the
user wants to serialize non-record types into SQL, then they must
explicitly opt into doing this by constructing a record or table with it
first. For a utility for inserting data into SQL, I think it makes more
sense to let the user choose how to convert their data, rather than make
a choice for them that may surprise them.

However, I understand this may be a controversial change. If the
maintainers don't agree, I can change this back.

#### Long switch names

The `file_name` and `table_name` long form switches are currently
snake_case and expect to be as such at the command line. These have been
changed to kebab-case to be more conventional.

# Tests + Formatting

To test the memory consumption, I used [this publicly available index of
all Wikipedia articles](https://dumps.wikimedia.org/enwiki/20230820/),
using the first 10,000, 100,000, and 1,000,000 entries, in that order. I
ran the following script to benchmark the changes against the current
stable release:

```nu
#!/usr/bin/nu

# let shellbin = $"($env.HOME)/src/nushell/target/aarch64-linux-android/release/nu"
let shellbin = "nu"
const dbpath = 'enwiki-index.db'

[10000, 100000, 1000000]
  | each {|rows|
      rm -f $dbpath;
      do { time -f '%M %e %U %S' $shellbin -c (
        $"bzip2 -cdk ~/enwiki-20230820-pages-articles-multistream-index.txt.bz2
            | head -n ($rows)
            | lines
            | parse '{offset}:{id}:{title}'
            | update cells -c [offset, id] { into int }
            | into sqlite ($dbpath)"
        )
      }
      | complete
      | get stderr
      | str trim
      | parse '{rss_max} {real} {user} {kernel}'
      | update cells -c [rss_max] { $"($in)kb" | into filesize }
      | update cells -c [real, user, kernel] { $"($in)sec" | into duration }
      | insert rows $rows
      | roll right
    }
  | flatten
  | to nuon
```

This yields the following results

Current stable release:

|rows|rss_max|real|user|kernel|
|-|-|-|-|-|
|10000|53.6 MiB|770ms|460ms|420ms|
|100000|209.6 MiB|6sec 940ms|3sec 740ms|4sec 380ms|
|1000000|1.7 GiB|1min 8sec 810ms|38sec 690ms|42sec 550ms|

This PR:

|rows|rss_max|real|user|kernel|
|-|-|-|-|-|
|10000|38.2 MiB|780ms|440ms|410ms|
|100000|39.8 MiB|6sec 450ms|3sec 530ms|4sec 160ms|
|1000000|39.8 MiB|1min 3sec 230ms|37sec 440ms|40sec 180ms|

# Note

I started this branch kind of at the same time as my others, but I
understand the feedback that smaller PRs are preferred. Let me know if
it would be better to split this up.

I do think the scope of the changes are on the bigger side even without
the behavior changes I mentioned, so I'm not sure if that will help this
particular PR very much, but I'm happy to oblige on request.

Do not block signals for child processes (#11402)
# Description / User-Facing Changes
Signals are no longer blocked for child processes launched from both
interactive and non-interactive mode. The only exception is that
`SIGTSTP`, `SIGTTIN`, and `SIGTTOU` remain blocked for child processes
launched only from **interactive** mode. This is to help prevent nushell
from getting into an unrecoverable state, since we don't support
background jobs. Anyways, this fully fixes #9026.

# Other Notes
- Needs Rust version `>= 1.66` for a fix in
`std::process::Command::spawn`, but it looks our current Rust version is
way above this.
- Uses `sigaction` instead of `signal`, since the behavior of `signal`
can apparently differ across systems. Also, the `sigaction` man page
says:
> The sigaction() function supersedes the signal() function, and should
be used in preference.

Additionally, using both `sigaction` and `signal` is not recommended.
Since we were already using `sigaction` in some places (and possibly
some of our dependencies as well), this PR replaces all usages of
`signal`.

# Tests
Might want to wait for #11178 for testing.

Allow plugins to receive configuration from the nushell configuration (#10955)
# Description

When nushell calls a plugin it now sends a configuration `Value` from
the nushell config under `$env.config.plugins.PLUGIN_SHORT_NAME`. This
allows plugin authors to read configuration provided by plugin users.

The `PLUGIN_SHORT_NAME` must match the registered filename after
`nu_plugin_`. If you register `target/debug/nu_plugin_config` the
`PLUGIN_NAME` will be `config` and the nushell config will loook like:

        $env.config = {
          # ...
          plugins: {
            config: [
              some
              values
            ]
          }
        }

Configuration may also use a closure which allows passing values from
`$env` to a plugin:

        $env.config = {
          # ...
          plugins: {
            config: {||
              $env.some_value
            }
          }
        }

This is a breaking change for the plugin API as the `Plugin::run()`
function now accepts a new configuration argument which is an
`&Option<Value>`. If no configuration was supplied the value is `None`.

Plugins compiled after this change should work with older nushell, and
will behave as if the configuration was not set.

Initially discussed in #10867

# User-Facing Changes

* Plugins can read configuration data stored in `$env.config.plugins`
* The plugin `CallInfo` now includes a `config` entry, existing plugins
will require updates

# Tests + Formatting

- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`

# After Submitting

adjust some commansd input_output type (#11436)
# Description
1. Make table to be a subtype of `list<any>`, so some input_output_types
of filter commands are unnecessary
2. Change some commands which accept an input type, but generates
different output types. In this case, delete duplicate entry, and change
relative output type to `<any>`

Yeah it makes some commands more permissive, but I think it's better to
run into strange issue that why my script runs to failed during parse
time.

fixes issue where comment and PI content was escaped even though [it
should not be](https://stackoverflow.com/a/46637835)

# User-Facing Changes
Correct comments and PIs
 `to xml --partial-escape` flag to emit less escaped characters

check existance w/o traversing symlinks (#10872)
# Description

Currently `path exists` checks the file/folder's existence by traversing
symlinks. I've added a `-n` switch/flag that disables symlink
traversing, similar to what `path expand -n` does.

## The Long Story (for those interested)

Hello! 👋 While working on one of my scripts, I discovered that the `path
exists` command was traversing symlinks. This meant that even if the
file existed, it would fail if the pointed location didn't exist. To
address this, I've introduced a new `-n` flag, which I borrowed from the
`path expand` command. This addition should make the behavior more
consistent within the *path commands universe*.

## But, is it any useful?
 
```nushell
let compat = /run/media/userX/DriveX/steam/steamapps/compatdata
if "symlink" == ($compat | path expand -n | path type) {}
# to this
if ($compat | path exists -n) {}
```

# User-Facing Changes

Users, will not efect. Unless they use the mentioned `-n` flag/switch.

Add file attribute handling flag to cp (#11491)
# Description
This PR adds possibility to preserve/strip attributes from files when
using `cp` (via uu_cp::Attributes). To achieve this a single `--preserve
<list of attributes>` flag is added. This is different from how
coreutils and uutils cp function, but I believe this is better for
nushell.

Coreutils cp has three options `-p`, `--preserve` and `--no-presevce`.
The logic of these two options is not straightforward. As far as I
understand it is:
1. By default only mode attributes are preserved
2. `--preserve` option adds to default preserved attributes specified
ones (e.g. `--preserve=xattr,timestamps` will preserve mode, timestamps
and xattr)
3. `-p` is the same as `--preserve=mode,ownership,timestamps`
4. `--no-preserve` option rejects specified attributes (having priority
over `--preserve`)

However (in my opinion) the `--no-preserve` option is not needed,
because its only use seems to be rejecting attributes preserved by
default. But there is no need for this in nushell, because `--preserve`
can be specified with empty list as argument (whereas coreutils cp will
display a `cp: ambiguous argument ‘’ for ‘--preserve’` error if
`--preserve` is used with empty string as argument).

So to simplify this command is suggest (and implemented) only the
`--preserve` with the following logic:
1. By default mode attribute is preserved (as in coreutils cp)
2. `--preserve [ ... ]` will overwrite default with whatever is
specified in list (empty list meaning preserve nothing)

This way cp without `--preserve` behaves the same as coreutils `cp`, but
instead of using combinations of `--preserve` and `--no-preserve` one
needs to use `--preserve [ ... ]` with all attributes specified
explicitly. This seems more user-friendly to me as it does not require
remembering what the attributes preserved by default are and rejecting
them manually. However I see the possible problem with behavior
different from coreutils implementation, so some feedback is
apprecieated!

# User-Facing Changes
Users can now preserve or reject file attributes when using `cp`

# Tests + Formatting
Added tests manipulating mode and timestamps attributes.

add type check during eval time (#11475)
# Description
Fixes: #11438 

Take the following as example:
```nushell
def spam [foo: string] {
    $'foo: ($foo | describe)'
}
def outer [--foo: string] {
    spam $foo
}

outer
```
When we call `outer`, type checker only check the all for `outer`, but
doesn't check inside the body of `outer`. This pr is trying to introduce
a type checking process through `Type::is_subtype()` during eval time.

## NOTE
I'm not really sure if it's easy to make a check inside the body of
`outer`. Adding an eval time type checker seems like an easier solution.
As a result: `outer` will be caught by runtime, not parse time type
checker

# User-Facing Changes

```nushell

Fix incorrect handling of boolean flags for builtin commands (#11492)
# Description
Possible fix of #11456
This PR fixes a bug where builtin commands did not respect the logic of
dynamically passed boolean flags. The reason is
[has_flag](6f59abaf43/crates/nu-protocol/src/ast/call.rs (L204C5-L212C6))
method did not evaluate and take into consideration expression used with
flag.

To address this issue a solution is proposed:
1. `has_flag` method is moved to `CallExt` and new logic to evaluate
expression and check if it is a boolean value is added
2. `has_flag_const` method is added to `CallExt` which is a constant
version of `has_flag`
3. `has_named` method is added to `Call` which is basically the old
logic of `has_flag`
4. All usages of `has_flag` in code are updated, mostly to pass
`engine_state` and `stack` to new `has_flag`. In `run_const` commands it
is replaced with `has_flag_const`. And in a few select places: parser,
`to nuon` and `into string` old logic via `has_named` is used.

# User-Facing Changes
Explicit values of boolean flags are now respected in builtin commands.

Simply, `""` doesn't exist. 

It's easy to test the truthfulness of this:

```rust
fn main() {
    println!("{}", std::path::Path::new("").exists());
}
```
gives `false`

Technically this is a breaking change, so:

When evaluating a closure (in
`EvalRuntime::eval_row_condition_or_closure()`), we try to resolve the
closure's block's captures, but we only check if they're variables on
the stack. We need to also check if they are constants (see the logic in
`Stack::gather_captures()`).

Xml errors fix (#11487)
# Description
Fixes #11264
This PR adds checks in `to xml` to output error for malformed xml
entries:
* With columns that are not one of `tag`, `attributes` or `content`
* With no `tag` when entry is not a string
* With `tag` that is not a string
This PR also replaces `attrs` with `attributes` in example and
extra_usage of `to xml` (column was originally named attrs and renamed
to attributes, but this was missed in docs)

# User-Facing Changes
`to xml` will produce error for conditions described above instead of
silently returning nothing

# Tests + Formatting
Added tests for `to xml` to check handling of malformed xml entries

Refactor tests (using cococo instead of ^echo) (#11479)
- related PR: #11478 

# Description

Now we can use `nu --testbin cococo` instead of `^echo` to echo messages
to stdout in tests.

But `nu` treats parameters as its own flags when parameter starts with
`-`. So `^echo --foo='bar'` still use `^echo`.

This reverts #10898 which breaks external completion.
Not having file completion fallback on empty result is **intentional**
as this indicates that there is nothing to complete at this position.
To have nushell fallback to file completion the external completer can
simply return *nothing*.


`NO RECORDS FOUND`:
```nushell
let external_completer = {|spans|
    []
}
```

Fallback to file completion:
```nushell
let external_completer = {|spans|
}
```

Finishes implementing https://github.com/nushell/nushell/issues/10598,
which asks for a spread operator in lists, in records, and when calling
commands.

# Description

Thank you for improving Nushell. Please, check our [contributing
guide](../CONTRIBUTING.md) and talk to the core team before making major
changes.

This PR will allow spreading arguments to commands (both internal and
external). It will also deprecate spreading arguments automatically when
passing to external commands.

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->

- Users will be able to use `...` to spread arguments to custom/builtin
commands that have rest parameters or allow unknown arguments, or to any
external command
- If a custom command doesn't have a rest parameter and it doesn't allow
unknown arguments either, the spread operator will not be allowed
- Passing lists to external commands without `...` will work for now but
will cause a deprecation warning saying that it'll stop working in 0.91
(is 2 versions enough time?)

Here's a function to help with demonstrating some behavior:
```nushell
> def foo [ a, b, c?, d?, ...rest ] { [$a $b $c $d $rest] | to nuon }
```

You can pass a list of arguments to fill in the `rest` parameter using
`...`:
```nushell
> foo 1 2 3 4 ...[5 6]
[1, 2, 3, 4, [5, 6]]
```

If you don't use `...`, the list `[5 6]` will be treated as a single
argument:

```nushell
> foo 1 2 3 4 [5 6] # Note the double [[]]
[1, 2, 3, 4, [[5, 6]]]
```

You can omit optional parameters before the spread arguments:
```nushell
> foo 1 2 3 ...[4 5] # d is omitted here
[1, 2, 3, null, [4, 5]]
```

If you have multiple lists, you can spread them all:
```nushell
> foo 1 2 3 ...[4 5] 6 7 ...[8] ...[]
[1, 2, 3, null, [4, 5, 6, 7, 8]]
```

Here's the kind of error you get when you try to spread arguments to a
command with no rest parameter:

![image](https://github.com/nushell/nushell/assets/45539777/93faceae-00eb-4e59-ac3f-17f98436e6e4)

And this is the warning you get when you pass a list to an external now
(without `...`):

Added tests to cover the following cases:
- Spreading arguments to a command that doesn't have a rest parameter
(unexpected spread argument error)
- Spreading arguments to a command that doesn't have a rest parameter
*but* there's also a missing positional argument (missing positional
error)
- Spreading arguments to a command that doesn't have a rest parameter
but does allow unknown arguments, such as `exec` (allowed)
- Spreading a list literal containing arguments of the wrong type (parse
error)
- Spreading a non-list value, both to internal and external commands
- Having named arguments in the middle of rest arguments
- `explain`ing a command call that spreads its arguments

# Examples

Suppose you have multiple tables:
```nushell
let people = [[id name age]; [0 alice 100] [1 bob 200] [2 eve 300]]
let evil_twins = [[id name age]; [0 ecila 100] [-1 bob 200] [-2 eve 300]]
```

Maybe you often find yourself needing to merge multiple tables and want
a utility to do that. You could write a function like this:
```nushell
def merge_all [ ...tables ] { $tables | reduce { |it, acc| $acc | merge $it } }
```

Then you can use it like this:
```nushell
> merge_all ...([$people $evil_twins] | each { |$it| $it | select name age })
╭───┬───────┬─────╮
│ # │ name  │ age │
├───┼───────┼─────┤
│ 0 │ ecila │ 100 │
│ 1 │ bob   │ 200 │
│ 2 │ eve   │ 300 │
╰───┴───────┴─────╯
```

Except they had duplicate columns, so now you first want to suffix every
column with a number to tell you which table the column came from. You
can make a command for that:
```nushell
def select_and_merge [ --cols: list<string>, ...tables ] {
  let renamed_tables = $tables
    | enumerate
    | each { |it|
      $it.item | select $cols | rename ...($cols | each { |col| $col + ($it.index | into string) })
    };
  merge_all ...$renamed_tables
}
```
And call it like this:
```nushell
> select_and_merge --cols [name age] $people $evil_twins
╭───┬───────┬──────┬───────┬──────╮
│ # │ name0 │ age0 │ name1 │ age1 │
├───┼───────┼──────┼───────┼──────┤
│ 0 │ alice │  100 │ ecila │  100 │
│ 1 │ bob   │  200 │ bob   │  200 │
│ 2 │ eve   │  300 │ eve   │  300 │
╰───┴───────┴──────┴───────┴──────╯
```

Suppose someone's made a command to search for APT packages:

```nushell
# The main command
def search-pkgs [
    --install                   # Whether to install any packages it finds
    log_level: int              # Pretend it's a good idea to make this a required positional parameter
    exclude?: list<string>      # Packages to exclude
    repositories?: list<string> # Which repositories to look in (searches in all if not given)
    ...pkgs                     # Package names to search for
] {
  { install: $install, log_level: $log_level, exclude: ($exclude | to nuon), repositories: ($repositories | to nuon), pkgs: ($pkgs | to nuon) }
}
```

It has a lot of parameters to configure it, so you might make your own
helper commands to wrap around it for specific cases. Here's one
example:
```nushell
# Only look for packages locally
def search-pkgs-local [
    --install              # Whether to install any packages it finds
    log_level: int
    exclude?: list<string> # Packages to exclude
    ...pkgs                # Package names to search for
] {
  # All required and optional positional parameters are given
  search-pkgs --install=$install $log_level [] ["<local URI or something>"] ...$pkgs
}
```
And you can run it like this:
```nushell
> search-pkgs-local --install=false 5 ...["python2.7" "vim"]
╭──────────────┬──────────────────────────────╮
│ install      │ false                        │
│ log_level    │ 5                            │
│ exclude      │ []                           │
│ repositories │ ["<local URI or something>"] │
│ pkgs         │ ["python2.7", vim]           │
╰──────────────┴──────────────────────────────╯
```

One thing I realized when writing this was that if we decide to not
allow passing optional arguments using the spread operator, then you can
(mis?)use the spread operator to skip optional parameters. Here, I
didn't want to give `exclude` explicitly, so I used a spread operator to
pass the packages to install. Without it, I would've needed to do
`search-pkgs-local --install=false 5 [] "python2.7" "vim"` (explicitly
pass `[]` (or `null`, in the general case) to `exclude`). There are
probably more idiomatic ways to do this, but I just thought it was
something interesting.

If you're a virologist of the [xkcd](https://xkcd.com/350/) kind,
another helper command you might make is this:
```nushell
# Install any packages it finds
def live-dangerously [ ...pkgs ] {
  # One optional argument was given (exclude), while another was not (repositories)
  search-pkgs 0 [] ...$pkgs --install # Flags can go after spread arguments
}
```

Running it:
```nushell
> live-dangerously "git" "*vi*" # *vi* because I don't feel like typing out vim and neovim
╭──────────────┬─────────────╮
│ install      │ true        │
│ log_level    │ 0           │
│ exclude      │ []          │
│ repositories │ null        │
│ pkgs         │ [git, *vi*] │
╰──────────────┴─────────────╯
```

Here's an example that uses the spread operator more than once within
the same command call:
```nushell
let extras = [ chrome firefox python java git ]

def search-pkgs-curated [ ...pkgs ] {
  (search-pkgs
      1
      [emacs]
      ["example.com", "foo.com"]
      vim # A must for everyone!
      ...($pkgs | filter { |p| not ($p | str contains "*") }) # Remove packages with globs
      python # Good tool to have
      ...$extras
      --install=false
      python3) # I forget, did I already put Python in extras?
}
```

Running it:
```nushell
> search-pkgs-curated "git" "*vi*"
╭──────────────┬───────────────────────────────────────────────────────────────────╮
│ install      │ false                                                             │
│ log_level    │ 1                                                                 │
│ exclude      │ [emacs]                                                           │
│ repositories │ [example.com, foo.com]                                            │
│ pkgs         │ [vim, git, python, chrome, firefox, python, java, git, "python3"] │

Allow http commands' automatic redirect-following to be disabled (#11329)
Intends to close #8920 

This PR suggests a new flag for the `http` commands, `--redirect-mode`,
which enables users to choose between different redirect handling modes.
The current behaviour of letting ureq silently follow redirects remains
the default, but two new options are introduced here, following the lead
of [JavaScript's `fetch`
API](https://developer.mozilla.org/en-US/docs/Web/API/fetch#redirect):
"manual", where any 3xx response to a request is simply returned as the
command's result, and "error", where any 3xx response causes a network
error like those caused by 4xx and 5xx responses.

This PR is a draft. Tests have not been added or run, the flag is
currently only implemented for the `http get` command, and design tweaks
are likely to be appropriate.

Most notably, it's not obvious to me whether a single flag which can
take one of three values is the nicest solution here.
We might instead consider two binary flags (like
`--no-following-redirects` and `--disallow-redirects`, although I'm bad
at naming things so I need help with that anyway), or completely drop
the "error" option if it's not deemed useful enough. (I personally think
it has some merit, especially since 4xx and 5xx responses are already
treated as errors by default; So this would allow users to treat only
immediate 2xx responses as success)

# User-facing changes
New options for the `http [method]` commands. Behaviour remains
unchanged when the command line flag introduced here is not used.

provided bytes don't exist. This doesn't seem to affect `bytes remove`
w/o flag or `bytes remove --all`.

# User-Facing Changes
Nushell doesn`t panic anymore.
