# Description
This PR changes the old performance logging with `Instant` timers. I'm
not sure if this is the best way to do it but it does help reveal where
time is being spent on startup. This is what it looks like when you
launch nushell with `cargo run -- --log-level info`. I'm using the
`info` log level exclusively for performance monitoring at this point.
## After Startup
Since you're in the repl, you can continue running commands. Here's the
output of `ls`, for instance.
Note that the above screenshots are in debug mode, so they're much
slower than release.
# User-Facing Changes
# Tests + Formatting
Don't forget to add tests that cover your changes.
Make sure you've run and fixed any issues with these commands:
- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A
clippy::needless_collect` to check that you're using the standard code
style
- `cargo test --workspace` to check that all tests pass
# After Submitting
If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.
# Description
This PR shows the startup time and decreases the banner. This startup
time output can be disabled with the `show_banner: false` setting in the
config. This is the startup in debug mode.
On my mac in release mode
```
Startup Time: 368ms 429µs 83ns
```
On my mac without a config as `nu --config foo --env-config foo`
```
Startup Time: 11ms 663µs 791ns
```
I could really go either way on this. If people don't like this change,
we don't have to merge it.

<blockquote>
<h1>Release rayon 1.6.1 (2022-12-09)</h1>
<ul>
<li>Simplified <code>par_bridge</code> to only pull one item at a time
from the iterator,
without batching. Threads that are waiting for iterator items will now
block
appropriately rather than spinning CPU. (Thanks <a
href="https://github.com/njaard"><code>@njaard</code></a>!)</li>
<li>Added protection against recursion in <code>par_bridge</code>, so
iterators that also
invoke rayon will not cause mutex recursion deadlocks.</li>
</ul>
<h1>Release rayon-core 1.10.1 (2022-11-18)</h1>
<ul>
<li>Fixed a race condition with threads going to sleep while a broadcast
starts.</li>
</ul>
<h1>Release rayon 1.6.0 / rayon-core 1.10.0 (2022-11-18)</h1>
<ul>
<li>The minimum supported <code>rustc</code> is now 1.56.</li>
<li>The new <code>IndexedParallelIterator::fold_chunks</code> and
<code>fold_chunks_with</code> methods
work like <code>ParallelIterator::fold</code> and <code>fold_with</code>
with fixed-size chunks of
items. This may be useful for predictable batching performance, without
the
allocation overhead of
<code>IndexedParallelIterator::chunks</code>.</li>
<li>New "broadcast" methods run a given function on all
threads in the pool.
These run at a sort of reduced priority after each thread has exhausted
their
local work queue, but before they attempt work-stealing from other
threads.
<ul>
<li>The global <code>broadcast</code> function and
<code>ThreadPool::broadcast</code> method will
block until completion, returning a <code>Vec</code> of all return
values.</li>
<li>The global <code>spawn_broadcast</code> function and methods on
<code>ThreadPool</code>, <code>Scope</code>,
and <code>ScopeFifo</code> will run detached, without blocking the
current thread.</li>
</ul>
</li>
<li>Panicking methods now use <code>#[track_caller]</code> to report the
caller's location.</li>
<li>Fixed a truncated length in <code>vec::Drain</code> when given an
empty range.</li>
</ul>

This is an attempt to implement a new `Value::LazyRecord` variant for
performance reasons.
`LazyRecord` is like a regular `Record`, but it's possible to access
individual columns without evaluating other columns. I've implemented
`LazyRecord` for the special `$nu` variable; accessing `$nu` is
relatively slow because of all the information in `scope`, and [`$nu`
accounts for about 2/3 of Nu's startup time on
Linux](https://github.com/nushell/nushell/issues/6677#issuecomment-1364618122).
### Benchmarks
I ran some benchmarks on my desktop (Linux, 12900K) and the results are
very pleasing.
Nu's time to start up and run a command (`cargo build --release;
hyperfine 'target/release/nu -c "echo \"Hello, world!\""' --shell=none
--warmup 10`) goes from **8.8ms to 3.2ms, about 2.8x faster**.
Tests are also much faster! Running `cargo nextest` (with our very slow
`proptest` tests disabled) goes from **7.2s to 4.4s (1.6x faster)**,
because most tests involve launching a new instance of Nu.
### Design (updated)
I've added a new `LazyRecord` trait and added a `Value` variant wrapping
those trait objects, much like `CustomValue`. `LazyRecord`
implementations must implement these 2 functions:
```rust
// All column names
fn column_names(&self) -> Vec<&'static str>;
// Get 1 specific column value
fn get_column_value(&self, column: &str) -> Result<Value, ShellError>;
```
### Serializability
`Value` variants must implement `Serializable` and `Deserializable`, which poses some problems because I want to use unserializable things like `EngineState` in `LazyRecord`s. To work around this, I basically lie to the type system:
1. Add `#[typetag::serde(tag = "type")]` to `LazyRecord` to make it serializable
2. Any unserializable fields in `LazyRecord` implementations get marked with `#[serde(skip)]`
3. At the point where a `LazyRecord` normally would get serialized and sent to a plugin, I instead collect it into a regular `Value::Record` (which can be serialized)
Previously the group check was only for the current users gid, now we
check against all the users groups.
# Description
Currently when using the `cd` command to enter a directory there was
only a check against the current user id, and exact current group id,
meaning if a directory had a group permission and that group wasn't the
users group it was effectively ignored.
The fix simply implements a check through all the users current groups.

So the following command
```
1..100 | each { |i| sleep 400ms; $i} | save --raw -f output.txt
```
Will stream data to `output.txt`
But I'm note sure how to make a proper test for it, so I leave with no
new test cases..
Also rename from `string_binary_list_value_to_bytes ` to
`value_to_bytes` to accepts more Value type.

# Description
Refactor command: "to url" in: "to url query". Changed usage sentence.
Closes: #7495
# User-Facing Changes
Now we get a query string from a record or table by using command: "to
url query".
```
> help to url query
Convert record or table into query string applying percent-encoding.
Usage:
> to url query
Flags:
-h, --help - Display the help message for this command
Signatures:
<record> | to url query -> <string>
<table> | to url query -> <string>
Examples:
Outputs a query string representing the contents of this record
> { mode:normal userid:31415 } | to url query
Outputs a query string representing the contents of this 1-row table
> [[foo bar]; ["1" "2"]] | to url query
Outputs a query string representing the contents of this record
> {a:"AT&T", b: "AT T"} | to url query
```
# Tests + Formatting
Added this test:
```
Example {
description: "Outputs a query string representing the contents of this record",
example: r#"{a:"AT&T", b: "AT T"} | to url query"#,
result: Some(Value::test_string("a=AT%26T&b=AT+T")),
},
```
to ensure percent-encoding.

If PR is accepted I'll open another PR on documentation to notify

# Description
This PR makes changes that allow underscores in numbers.
Example:
```nu
# allows underscores to be placed arbitrarily to enhance readability.
let pi = 3.1415_9265_3589_793
# works with integers
let num = 1_000_000_000_000
let fav_color = 0x68_9d_6a
```
I have changed `assert!(a == b)` calls to `assert_eq!(a, b)`, which give
better error messages. Similarly for `assert!(a != b)` and
`assert_ne!(a, b)`. Basically all instances were comparing primitives
(string slices or integers), so there is no loss of generality from
special-case macros,
I have also fixed a number of typos in comments, variable names, and a
few user-facing messages.
