## Summary
It turns out that `a.` isn't a list format supported by rustdoc. I
changed the documentation to use `1.`, `2.` instead.

## Summary
I decided to disable the new
[`needless_continue`](https://rust-lang.github.io/rust-clippy/master/index.html#needless_continue)
rule because I often found the explicit `continue` more readable over an
empty block or having to invert the condition of an other branch.

Update to latest Salsa main branch, so as to get a baseline for
measuring the perf effect of https://github.com/salsa-rs/salsa/pull/786
on red-knot in isolation from other recent changes in Salsa main branch.
## Summary
This PR adds a new but so far empty and unused `red_knot_ide` crate.
This new crate's purpose is to implement IDE-specific functionality,
such as go to definition, hover, completion, etc., which are used by
both the LSP and the playground.
The crate itself doesn't depend on `lsptypes`. The idea is that the
facade crates (e.g., `red_knot_server`) convert external to internal
types.
Not only allows this to share the logic between server and playground,
it also ensures that the core functionality is easier to test because it
can be tested without needing a full LSP.
## Test Plan
`cargo build`
## Summary
Another salsa upgrade.
The main motivation is to stay on a recent salsa version because there
are still a lot of breaking changes happening.
The most significant changes in this update:
* Salsa no longer derives `Debug` by default. It now requires
`interned(debug)` (or similar)
* This version ships the foundation for garbage collecting interned
values. However, this comes at the cost that queries now track which
interned values they created (or read). The micro benchmarks in the
salsa repo showed a significant perf regression. Will see if this also
visible in our benchmarks.
## Test Plan
`cargo test`
Pulls in the latest Salsa main branch, which supports fixpoint
iteration, and uses it to handle all query cycles.
With this, we no longer need to skip any corpus files to avoid panics.
Latest perf results show a 6% incremental and 1% cold-check regression.
This is not a "no cycles" regression, as tomllib and typeshed do trigger
some definition cycles (previously handled by our old
`infer_definition_types` fallback to `Unknown`). We don't currently have
a benchmark we can use to measure the pure no-cycles regression, though
I expect there would still be some regression; the fixpoint iteration
feature in Salsa does add some overhead even for non-cyclic queries.
I think this regression is within the reasonable range for this feature.
We can do further optimization work later, but I don't think it's the
top priority right now. So going ahead and acknowledging the regression
on CodSpeed.
Mypy primer is happy, so this doesn't regress anything on our
currently-checked projects. I expect it probably unlocks adding a number
of new projects to our ecosystem check that previously would have
panicked.
Fixes#13792Fixes#14672
Update to latest Salsa main branch. This provides a point of comparison
for the perf impact of fixpoint iteration, which is based on latest
Salsa main.
This requires an update to the locked version of our boxcar dep, since
Salsa now depends on a newer version of boxcar.
## Summary
Transition to using coarse-grained tracked structs (depends on
https://github.com/salsa-rs/salsa/pull/657). For now, this PR doesn't
add any `#[tracked]` fields, meaning that any changes cause the entire
struct to be invalidated. It also changes `AstNodeRef` to be
compared/hashed by pointer address, instead of performing a deep AST
comparison.
## Test Plan
This yields a 10-15% improvement on my machine (though weirdly some runs
were 5-10% without being flagged as inconsistent by criterion, is there
some non-determinism involved?). It's possible that some of this is
unrelated, I'll try applying the patch to the current salsa version to
make sure.

This is pretty much just moving to the new API and taking care to use
byte offsets. This is *almost* enough. The next commit will fix a bug
involving the handling of unprintable characters as a result of
switching to byte offsets.
This merely adds the crate to our repository. Some cosmetic changes are
made to make it work in our repo and follow our conventions, such as
changing the name to `ruff_annotate_snippets`. We retain the original
license information. We do drop some things, such as benchmarks, but
keep tests and examples.
## Summary
Adds a markdown-based test framework for writing tests of type inference
and type checking. Fixes#11664.
Implements the basic required features. A markdown test file is a suite
of tests, each test can contain one or more Python files, with
optionally specified path/name. The test writes all files to an
in-memory file system, runs red-knot, and matches the resulting
diagnostics against `Type: ` and `Error: ` assertions embedded in the
Python source as comments.
We will want to add features like incremental tests, setting custom
configuration for tests, writing non-Python files, testing syntax
errors, capturing full diagnostic output, etc. There's also plenty of
room for improved UX (colored output?).
## Test Plan
Lots of tests!
Sample of the current output when a test fails:
```

## Summary
This PR changes removes the typeshed stubs from the vendored file system
shipped with ruff
and instead ships an empty "typeshed".
Making the typeshed files optional required extracting the typshed files
into a new `ruff_vendored` crate. I do like this even if all our builds
always include typeshed because it means `red_knot_python_semantic`
contains less code that needs compiling.
This also allows us to use deflate because the compression algorithm
doesn't matter for an archive containing a single, empty file.
## Test Plan
`cargo test`
I verified with ` cargo tree -f "{p} {f}" -p <package> ` that:
* red_knot_wasm: enables `deflate` compression
* red_knot: enables `zstd` compression
* `ruff`: uses stored
I'm not quiet sure how to build the binary that maturin builds but
comparing the release artifact size with `strip = true` shows a `1.5MB`
size reduction

## Summary
This PR adds an experimental Ruff subcommand to generate dependency
graphs based on module resolution.
A few highlights:
- You can generate either dependency or dependent graphs via the
`--direction` command-line argument.
- Like Pants, we also provide an option to identify imports from string
literals (`--detect-string-imports`).
- Users can also provide additional dependency data via the
`include-dependencies` key under `[tool.ruff.import-map]`. This map uses
file paths as keys, and lists of strings as values. Those strings can be
file paths or globs.
The dependency resolution uses the red-knot module resolver which is
intended to be fully spec compliant, so it's also a chance to expose the
module resolver in a real-world setting.
The CLI is, e.g., `ruff graph build ../autobot`, which will output a
JSON map from file to files it depends on for the `autobot` project.

## Summary
This PR separates the current `red_knot` crate into two crates:
1. `red_knot` - This will be similar to the `ruff` crate, it'll act as
the CLI crate
2. `red_knot_workspace` - This includes everything except for the CLI
functionality from the existing `red_knot` crate
Note that the code related to the file watcher is in
`red_knot_workspace` for now but might be required to extract it out in
the future.
The main motivation for this change is so that we can have a `red_knot
server` command. This makes it easier to test the server out without
making any changes in the VS Code extension. All we need is to specify
the `red_knot` executable path in `ruff.path` extension setting.
## Test Plan
- `cargo build`
- `cargo clippy --workspace --all-targets --all-features`
- `cargo shear --fix`
We can't just directly update the `release.yml` file because that's
auto-generated using `cargo-dist`. So, update the permissions in
`Cargo.toml` and then use `cargo dist generate` to make sure there's no
diff.
Intern types using Salsa interning instead of in the `TypeInference`
result.
This eliminates the need for `TypingContext`, and also paves the way for
finer-grained type inference queries.
## Summary
These are now `post-announce-jobs`. So if they fail, the release itself
will still succeed, which seems ok. (If we make them `publish-jobs`,
then we might end up publishing to PyPI but failing the release itself
if one of these fails.)
The intent is that these are still runnable via `workflow_dispatch` too.
Closes https://github.com/astral-sh/ruff/issues/12074.
## Summary
This PR migrates our release workflow to
[`cargo-dist`](https://github.com/axodotdev/cargo-dist). The primary
motivation here is that we want to ship dedicated installers for Ruff
that work across platforms, and `cargo-dist` gives us those installers
out-of-the-box. The secondary motivation is that `cargo-dist` formalizes
some of the patterns that we've built up over time in our own release
process.
At a high level:
- The `release.yml` file is generated by `cargo-dist` with `cargo dist
generate`. It doesn't contain any modifications vis-a-vis the generated
file. (If it's edited out of band from generation, the release fails.)
- Our customizations are inserted as custom steps within the
`cargo-dist` workflow. Specifically, `build-binaries` builds the wheels
and packages them into binaries (as on `main`), while `build-docker.yml`
builds the Docker image. `publish-pypi.yml` publishes the wheels to
PyPI. This is effectively our `release.yaml` (on `main`), broken down
into individual workflows rather than steps within a single workflow.
### Changes from `main`
The workflow is _nearly_ unchanged. We kick off a release manually via
the GitHub Action by providing a tag. If the tag doesn't match the
`Cargo.toml`, the release fails. If the tag matches an already-existing
release, the release fails.
The release proceeds by (in order):
0. Doing some upfront validation via `cargo-dist`.
1. Creating the wheels and archives.
2. Building and pushing the Docker image.
3. Publishing to PyPI (if it's not a "dry run").
4. Creating the GitHub Release (if it's not a "dry run").
5. Notifying `ruff-pre-commit` (if it's not a "dry run").
There are a few changes in the workflow as compared to `main`:
- **We no longer validate the SHA** (just the tag). It's not an input to
the job. The Axo team is considering whether / how to support this.
- **Releases are now published directly** (rather than as draft). Again,
the Axo team is considering whether / how to support this. The downside
of drafts is that the URLs aren't stable, so the installers don't work
_as long as the release is in draft_. This is fine for our workflow. It
seems like the Axo team will add it.
- Releases already contain the latest entry from the changelog (we don't
need to copy it over). This "Just Works", which is nice, though we'll
still want to edit them to add contributors.
There are also a few **breaking changes** for consumers of the binaries:
- **We no longer include the version tag in the file name**. This
enables users to install via `/latest` URLs on GitHub, and is part of
the cargo-dist paradigm.
- **Archives now include an extra level of nesting,** which you can
remove with `--strip-components=1` when untarring.
Here's an example release that I created -- I omitted all the artifacts
since I was just testing a workflow, so none of the installers or links
work, but it gives you a sense for what the release looks like:
https://github.com/charliermarsh/cargodisttest/releases/tag/0.1.13.
### Test Plan
I ran a successful release to completion last night, and installed Ruff
via the installer:
The piece I'm least confident about is the Docker push. We build the
image, but the push fails in my test repo since I haven't wired up the
credentials.
## Summary
This PR removes the `result-like` dependency and instead implement the
required functionality. The motivation being that `noqa.is_enabled()` is
easier to read than `noqa.into()`.
For context, I was just trying to understand the syntax error workflow
and I saw these flags which were being converted via `into`. I always
find `into` confusing because you never know what's it being converted
into unless you know the type. Later realized that it's just a boolean
flag. After removing the usages from these two flags, it turns out that
the dependency is only being used in one rule so I thought to remove
that as well.
## Test Plan
`cargo insta test`
## Summary
This change adds a GitHub Actions CI job to check that the project
builds and test pass under the declared minimum supported rust compiler.
I have bumped the msrv to 1.74 as that is the lowest version I could get
this project to build on.
## Test Plan
The CI job has run on this PR, and will also run on the main branch.
## Summary
Closes https://github.com/astral-sh/ruff/issues/10858.
`ruff server` now supports `*.ipynb` (aka Jupyter Notebook) files.
Extensive internal changes have been made to facilitate this, which I've
done some work to contextualize with documentation and an pre-review
that highlights notable sections of the code.
`*.ipynb` cells should behave similarly to `*.py` documents, with one
major exception. The format command `ruff.applyFormat` will only apply
to the currently selected notebook cell - if you want to format an
entire notebook document, use `Format Notebook` from the VS Code context
menu.
## Test Plan
The VS Code extension does not yet have Jupyter Notebook support
enabled, so you'll first need to enable it manually. To do this,
checkout the `pre-release` branch and modify `src/common/server.ts` as
follows:
Before:
After:
I recommend testing this PR with large, complicated notebook files. I
used notebook files from [this popular
repository](https://github.com/jakevdp/PythonDataScienceHandbook/tree/master/notebooks)
in my preliminary testing.
The main thing to test is ensuring that notebook cells behave the same
as Python documents, besides the aforementioned issue with
`ruff.applyFormat`. You should also test adding and deleting cells (in
particular, deleting all the code cells and ensure that doesn't break
anything), changing the kind of a cell (i.e. from markup -> code or vice
versa), and creating a new notebook file from scratch. Finally, you
should also test that source actions work as expected (and across the
entire notebook).
Note: `ruff.applyAutofix` and `ruff.applyOrganizeImports` are currently
broken for notebook files, and I suspect it has something to do with
https://github.com/astral-sh/ruff/issues/11248. Once this is fixed, I
will update the test plan accordingly.

## Summary
Continuation of https://github.com/astral-sh/ruff/pull/9444.
> When the formatter is fully cached, it turns out we actually spend
meaningful time mapping from file to `Settings` (since we use a
hierarchical approach to settings). Using `matchit` rather than
`BTreeMap` improves fully-cached performance by anywhere from 2-5%
depending on the project, and since these are all implementation details
of `Resolver`, it's minimally invasive.
`matchit` supports escaping routing characters so this change should now
be fully compatible.
## Test Plan
On my machine I'm seeing a ~3% improvement with this change.

## Summary
This PR replaces the current parser generated from LALRPOP to a
hand-written recursive descent parser.
It also updates the grammar for [PEP
646](https://peps.python.org/pep-0646/) so that the parser outputs the
correct AST. For example, in `data[*x]`, the index expression is now a
tuple with a single starred expression instead of just a starred
expression.
Beyond the performance improvements, the parser is also error resilient
and can provide better error messages. The behavior as seen by any
downstream tools isn't changed. That is, the linter and formatter can
still assume that the parser will _stop_ at the first syntax error. This
will be updated in the following months.
For more details about the change here, refer to the PR corresponding to
the individual commits and the release blog post.
## Test Plan
Write _lots_ and _lots_ of tests for both valid and invalid syntax and
verify the output.

## Summary
This PR introduces the `ruff_server` crate and a new `ruff server`
command. `ruff_server` is a re-implementation of
[`ruff-lsp`](https://github.com/astral-sh/ruff-lsp), written entirely in
Rust. It brings significant performance improvements, much tighter
integration with Ruff, a foundation for supporting entirely new language
server features, and more!
This PR is an early version of `ruff_lsp` that we're calling the
**pre-release** version. Anyone is more than welcome to use it and
submit bug reports for any issues they encounter - we'll have some
documentation on how to set it up with a few common editors, and we'll
also provide a pre-release VSCode extension for those interested.
This pre-release version supports:
- **Diagnostics for `.py` files**
- **Quick fixes**
- **Full-file formatting**
- **Range formatting**
- **Multiple workspace folders**
- **Automatic linter/formatter configuration** - taken from any
`pyproject.toml` files in the workspace.
Many thanks to @MichaReiser for his [proof-of-concept
work](https://github.com/astral-sh/ruff/pull/7262), which was important
groundwork for making this PR possible.
## Architectural Decisions
I've made an executive choice to go with `lsp-server` as a base
framework for the LSP, in favor of `tower-lsp`. There were several
reasons for this:
1. I would like to avoid `async` in our implementation. LSPs are mostly
computationally bound rather than I/O bound, and `async` adds a lot of
complexity to the API, while also making harder to reason about
execution order. This leads into the second reason, which is...
2. Any handlers that mutate state should be blocking and run in the
event loop, and the state should be lock-free. This is the approach that
`rust-analyzer` uses (also with the `lsp-server`/`lsp-types` crates as a
framework), and it gives us assurances about data mutation and execution
order. `tower-lsp` doesn't support this, which has caused some
[issues](https://github.com/ebkalderon/tower-lsp/issues/284) around data
races and out-of-order handler execution.
3. In general, I think it makes sense to have tight control over
scheduling and the specifics of our implementation, in exchange for a
slightly higher up-front cost of writing it ourselves. We'll be able to
fine-tune it to our needs and support future LSP features without
depending on an upstream maintainer.
## Test Plan
The pre-release of `ruff_server` will have snapshot tests for common
document editing scenarios. An expanded test suite is on the roadmap for
future version of `ruff_server`.
## Summary
Allows `required-version` to be set with a version specifier, like
`>=0.3.1`.
If a single version is provided, falls back to assuming `==0.3.1`, for
backwards compatibility.
