Improve working with `IntoValue` and `FromValue` for byte collections (#13641) <!-- if this PR closes one or more issues, you can automatically link the PR with them by using one of the [*linking keywords*](https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue#linking-a-pull-request-to-an-issue-using-a-keyword), e.g. - this PR should close #xxxx - fixes #xxxx you can also mention related issues, PRs or discussions! --> # Description <!-- Thank you for improving Nushell. Please, check our [contributing guide](../CONTRIBUTING.md) and talk to the core team before making major changes. Description of your pull request goes here. **Provide examples and/or screenshots** if your changes affect the user experience. --> I was working with byte collections like `Vec<u8>` and [`bytes::Bytes`](https://docs.rs/bytes/1.7.1/bytes/struct.Bytes.html), both are currently not possible to be used directly in a struct that derives `IntoValue` and `FromValue` at the same time. The `Vec<u8>` will convert itself into a `Value::List` but expects a `Value::String` or `Value::Binary` to load from. I now also implemented that it can load from `Value::List` just like the other `Vec<uX>` versions. For further working with byte collections the type `bytes::Bytes` is wildly used, therefore I added a implementation for it. `bytes` is already part of the dependency graph as many crates (more than 5000 to crates.io) use it. # User-Facing Changes <!-- List of all changes that impact the user experience here. This helps us keep track of breaking changes. --> User of `nu-protocol` as library, e.g. plugin developers, can now use byte collections more easily in their data structures and derive `IntoValue` and `FromValue` for it. # Tests + Formatting <!-- Don't forget to add tests that cover your changes.

So in this PR replaced the use `convert_case` with `heck`. Mostly I rebuilt the `convert_case` API with `heck` to work with it as I like the API of `convert_case` more than `heck`. # User-Facing Changes <!-- List of all changes that impact the user experience here.

Replace `ExternalStream` with new `ByteStream` type (#12774) # Description This PR introduces a `ByteStream` type which is a `Read`-able stream of bytes. Internally, it has an enum over three different byte stream sources: ```rust pub enum ByteStreamSource { Read(Box<dyn Read + Send + 'static>), File(File), Child(ChildProcess), } ``` This is in comparison to the current `RawStream` type, which is an `Iterator<Item = Vec<u8>>` and has to allocate for each read chunk. Currently, `PipelineData::ExternalStream` serves a weird dual role where it is either external command output or a wrapper around `RawStream`. `ByteStream` makes this distinction more clear (via `ByteStreamSource`) and replaces `PipelineData::ExternalStream` in this PR: ```rust pub enum PipelineData { Empty, Value(Value, Option<PipelineMetadata>), ListStream(ListStream, Option<PipelineMetadata>), ByteStream(ByteStream, Option<PipelineMetadata>), } ``` The PR is relatively large, but a decent amount of it is just repetitive changes. This PR fixes #7017, fixes #10763, and fixes #12369. This PR also improves performance when piping external commands. Nushell should, in most cases, have competitive pipeline throughput compared to, e.g., bash. | Command | Before (MB/s) | After (MB/s) | Bash (MB/s) | | -------------------------------------------------- | -------------:| ------------:| -----------:| | `throughput \| rg 'x'` | 3059 | 3744 | 3739 | | `throughput \| nu --testbin relay o> /dev/null` | 3508 | 8087 | 8136 | # User-Facing Changes - This is a breaking change for the plugin communication protocol, because the `ExternalStreamInfo` was replaced with `ByteStreamInfo`. Plugins now only have to deal with a single input stream, as opposed to the previous three streams: stdout, stderr, and exit code. - The output of `describe` has been changed for external/byte streams. - Temporary breaking change: `bytes starts-with` no longer works with byte streams. This is to keep the PR smaller, and `bytes ends-with` already does not work on byte streams. - If a process core dumped, then instead of having a `Value::Error` in the `exit_code` column of the output returned from `complete`, it now is a `Value::Int` with the negation of the signal number. # After Submitting - Update docs and book as necessary - Release notes (e.g., plugin protocol changes) - Adapt/convert commands to work with byte streams (high priority is `str length`, `bytes starts-with`, and maybe `bytes ends-with`). - Refactor the `tee` code, Devyn has already done some work on this. --------- Co-authored-by: Devyn Cairns <devyn.cairns@gmail.com>

Internal representation (IR) compiler and evaluator (#13330) # Description This PR adds an internal representation language to Nushell, offering an alternative evaluator based on simple instructions, stream-containing registers, and indexed control flow. The number of registers required is determined statically at compile-time, and the fixed size required is allocated upon entering the block. Each instruction is associated with a span, which makes going backwards from IR instructions to source code very easy. Motivations for IR: 1. **Performance.** By simplifying the evaluation path and making it more cache-friendly and branch predictor-friendly, code that does a lot of computation in Nushell itself can be sped up a decent bit. Because the IR is fairly easy to reason about, we can also implement optimization passes in the future to eliminate and simplify code. 2. **Correctness.** The instructions mostly have very simple and easily-specified behavior, so hopefully engine changes are a little bit easier to reason about, and they can be specified in a more formal way at some point. I have made an effort to document each of the instructions in the docs for the enum itself in a reasonably specific way. Some of the errors that would have happened during evaluation before are now moved to the compilation step instead, because they don't make sense to check during evaluation. 3. **As an intermediate target.** This is a good step for us to bring the [`new-nu-parser`](https://github.com/nushell/new-nu-parser) in at some point, as code generated from new AST can be directly compared to code generated from old AST. If the IR code is functionally equivalent, it will behave the exact same way. 4. **Debugging.** With a little bit more work, we can probably give control over advancing the virtual machine that `IrBlock`s run on to some sort of external driver, making things like breakpoints and single stepping possible. Tools like `view ir` and [`explore ir`](https://github.com/devyn/nu_plugin_explore_ir) make it easier than before to see what exactly is going on with your Nushell code. The goal is to eventually replace the AST evaluator entirely, once we're sure it's working just as well. You can help dogfood this by running Nushell with `$env.NU_USE_IR` set to some value. The environment variable is checked when Nushell starts, so config runs with IR, or it can also be set on a line at the REPL to change it dynamically. It is also checked when running `do` in case within a script you want to just run a specific piece of code with or without IR. # Example ```nushell view ir { |data| mut sum = 0 for n in $data { $sum += $n } $sum } ``` ```gas # 3 registers, 19 instructions, 0 bytes of data 0: load-literal %0, int(0) 1: store-variable var 904, %0 # let 2: drain %0 3: drop %0 4: load-variable %1, var 903 5: iterate %0, %1, end 15 # for, label(1), from(14:) 6: store-variable var 905, %0 7: load-variable %0, var 904 8: load-variable %2, var 905 9: binary-op %0, Math(Plus), %2 10: span %0 11: store-variable var 904, %0 12: load-literal %0, nothing 13: drain %0 14: jump 5 15: drop %0 # label(0), from(5:) 16: drain %0 17: load-variable %0, var 904 18: return %0 ``` # Benchmarks All benchmarks run on a base model Mac Mini M1. ## Iterative Fibonacci sequence This is about as best case as possible, making use of the much faster control flow. Most code will not experience a speed improvement nearly this large. ```nushell def fib [n: int] { mut a = 0 mut b = 1 for _ in 2..=$n { let c = $a + $b $a = $b $b = $c } $b } use std bench bench { 0..50 | each { |n| fib $n } } ``` IR disabled: ``` ╭───────┬─────────────────╮ │ mean │ 1ms 924µs 665ns │ │ min │ 1ms 700µs 83ns │ │ max │ 3ms 450µs 125ns │ │ std │ 395µs 759ns │ │ times │ [list 50 items] │ ╰───────┴─────────────────╯ ``` IR enabled: ``` ╭───────┬─────────────────╮ │ mean │ 452µs 820ns │ │ min │ 427µs 417ns │ │ max │ 540µs 167ns │ │ std │ 17µs 158ns │ │ times │ [list 50 items] │ ╰───────┴─────────────────╯ ``` ![explore ir view](https://github.com/nushell/nushell/assets/10729/d7bccc03-5222-461c-9200-0dce71b83b83) ## [gradient_benchmark_no_check.nu](https://github.com/nushell/nu_scripts/blob/main/benchmarks/gradient_benchmark_no_check.nu) IR disabled: ``` ╭───┬──────────────────╮ │ 0 │ 27ms 929µs 958ns │ │ 1 │ 21ms 153µs 459ns │ │ 2 │ 18ms 639µs 666ns │ │ 3 │ 19ms 554µs 583ns │ │ 4 │ 13ms 383µs 375ns │ │ 5 │ 11ms 328µs 208ns │ │ 6 │ 5ms 659µs 542ns │ ╰───┴──────────────────╯ ``` IR enabled: ``` ╭───┬──────────────────╮ │ 0 │ 22ms 662µs │ │ 1 │ 17ms 221µs 792ns │ │ 2 │ 14ms 786µs 708ns │ │ 3 │ 13ms 876µs 834ns │ │ 4 │ 13ms 52µs 875ns │ │ 5 │ 11ms 269µs 666ns │ │ 6 │ 6ms 942µs 500ns │ ╰───┴──────────────────╯ ``` ## [random-bytes.nu](https://github.com/nushell/nu_scripts/blob/main/benchmarks/random-bytes.nu) I got pretty random results out of this benchmark so I decided not to include it. Not clear why. # User-Facing Changes - IR compilation errors may appear even if the user isn't evaluating with IR. - IR evaluation can be enabled by setting the `NU_USE_IR` environment variable to any value. - New command `view ir` pretty-prints the IR for a block, and `view ir --json` can be piped into an external tool like [`explore ir`](https://github.com/devyn/nu_plugin_explore_ir). # Tests + Formatting All tests are passing with `NU_USE_IR=1`, and I've added some more eval tests to compare the results for some very core operations. I will probably want to add some more so we don't have to always check `NU_USE_IR=1 toolkit test --workspace` on a regular basis. # After Submitting - [ ] release notes - [ ] further documentation of instructions? - [ ] post-release: publish `nu_plugin_explore_ir`

Migrate to a new PWD API (#12603) This is the first PR towards migrating to a new `$env.PWD` API that returns potentially un-canonicalized paths. Refer to PR #12515 for motivations. ## New API: `EngineState::cwd()` The goal of the new API is to cover both parse-time and runtime use case, and avoid unintentional misuse. It takes an `Option<Stack>` as argument, which if supplied, will search for `$env.PWD` on the stack in additional to the engine state. I think with this design, there's less confusion over parse-time and runtime environments. If you have access to a stack, just supply it; otherwise supply `None`. ## Deprecation of other PWD-related APIs Other APIs are re-implemented using `EngineState::cwd()` and properly documented. They're marked deprecated, but their behavior is unchanged. Unused APIs are deleted, and code that accesses `$env.PWD` directly without using an API is rewritten. Deprecated APIs: * `EngineState::current_work_dir()` * `StateWorkingSet::get_cwd()` * `env::current_dir()` * `env::current_dir_str()` * `env::current_dir_const()` * `env::current_dir_str_const()` Other changes: * `EngineState::get_cwd()` (deleted) * `StateWorkingSet::list_env()` (deleted) * `repl::do_run_cmd()` (rewritten with `env::current_dir_str()`) ## `cd` and `pwd` now use logical paths by default This pulls the changes from PR #12515. It's currently somewhat broken because using non-canonicalized paths exposed a bug in our path normalization logic (Issue #12602). Once that is fixed, this should work. ## Future plans This PR needs some tests. Which test helpers should I use, and where should I put those tests? I noticed that unquoted paths are expanded within `eval_filepath()` and `eval_directory()` before they even reach the `cd` command. This means every paths is expanded twice. Is this intended? Once this PR lands, the plan is to review all usages of the deprecated APIs and migrate them to `EngineState::cwd()`. In the meantime, these usages are annotated with `#[allow(deprecated)]` to avoid breaking CI. --------- Co-authored-by: Jakub Žádník <kubouch@gmail.com>

Add Stack::stdout_file and Stack::stderr_file to capture stdout/-err of external commands (#12857) # Description In this PR I added two new methods to `Stack`, `stdout_file` and `stderr_file`. These two modify the inner `StackOutDest` and set a `File` into the `stdout` and `stderr` respectively. Different to the `push_redirection` methods, these do not require to hold a guard up all the time but require ownership of the stack. This is primarly useful for applications that use `nu` as a language but not the `nushell`. This PR replaces my first attempt #12851 to add a way to capture stdout/-err of external commands. Capturing the stdout without having to write into a file is possible with crates like [`os_pipe`](https://docs.rs/os_pipe), an example for this is given in the doc comment of the `stdout_file` command and can be executed as a doctest (although it doesn't validate that you actually got any data). This implementation takes `File` as input to make it easier to implement on different operating systems without having to worry about `OwnedHandle` or `OwnedFd`. Also this doesn't expose any use `os_pipe` to not leak its types into this API, making it depend on it. As in my previous attempt, @IanManske guided me here. # User-Facing Changes This change has no effect on `nushell` and therefore no user-facing changes. # Tests + Formatting This only exposes a new way of using already existing code and has therefore no further testing. The doctest succeeds on my machine at least (x86 Windows, 64 Bit). # After Submitting All the required documentation is already part of this PR.
