Rename `SemanticModel::is_builtin` to `SemanticModel::has_builtin_binding` (#10991) 2024-04-18 11:11:42 +01:00
Charlie Marsh bc9b4571eb
Avoid failures due to non-deterministic binding ordering (#10478)
## Summary

We're seeing failures in https://github.com/astral-sh/ruff/issues/10470
because `resolve_qualified_import_name` isn't guaranteed to return a
specific import if a symbol is accessible in two ways (e.g., you have
both `import logging` and `from logging import error` in scope, and you
want `logging.error`). This PR breaks up the failing tests such that the
imports aren't in the same scope.

Closes https://github.com/astral-sh/ruff/issues/10470.

## Test Plan

I added a `bindings.reverse()` to `resolve_qualified_import_name` to
ensure that the tests pass regardless of the binding order.

Split `CallPath` into `QualifiedName` and `UnqualifiedName` (#10210)
## Summary

Charlie can probably explain this better than I but it turns out,
`CallPath` is used for two different things:

* To represent unqualified names like `version` where `version` can be a
local variable or imported (e.g. `from sys import version` where the
full qualified name is `sys.version`)
* To represent resolved, full qualified names

This PR splits `CallPath` into two types to make this destinction clear.

> Note: I haven't renamed all `call_path` variables to `qualified_name`
or `unqualified_name`. I can do that if that's welcomed but I first want
to get feedback on the approach and naming overall.

## Test Plan

`cargo test`

CallPath newtype wrapper (#10201)
## Summary

This PR changes the `CallPath` type alias to a newtype wrapper. 

A newtype wrapper allows us to limit the API and to experiment with
alternative ways to implement matching on `CallPath`s.

Track top-level module imports in the semantic model (#9775)
## Summary

This is a simple idea to avoid unnecessary work in the linter,
especially for rules that run on all name and/or all attribute nodes.
Imagine a rule like the NumPy deprecation check. If the user never
imported `numpy`, we should be able to skip that rule entirely --
whereas today, we do a `resolve_call_path` check on _every_ name in the
file. It turns out that there's basically a finite set of modules that
we care about, so we now track imports on those modules as explicit
flags on the semantic model. In rules that can _only_ ever trigger if
those modules were imported, we add a dedicated and extremely cheap
check to the top of the rule.

We could consider generalizing this to all modules, but I would expect
that not to be much faster than `resolve_call_path`, which is just a
hash map lookup on `TextSize` anyway.

It would also be nice to make this declarative, such that rules could
declare the modules they care about, the analyzers could call the rules
as appropriate. But, I don't think such a design should block merging
this.

Update applicability messages for clarity in tests (#8541)
These names are only ever displayed internally right now and we could be
clearer in our test snapshots.

The diff is kind of scary because all of the tests fixtures are updated.

Avoid including literal `shell=True` for truthy, non-`True` diagnostics (#8359)
## Summary

If the value of `shell` wasn't literally `True`, we now show a message
describing it as truthy, rather than the (misleading) `shell=True`
literal in the diagnostic.

Closes https://github.com/astral-sh/ruff/issues/8310.

Remove per-diagnostic check for fixability (#7919)
## Summary

Throughout the codebase, we have this pattern:

```rust
let mut diagnostic = ...
if checker.patch(Rule::UnusedVariable) {
    // Do the fix.
}
diagnostics.push(diagnostic)
```

This was helpful when we computed fixes lazily; however, we now compute
fixes eagerly, and this is _only_ used to ensure that we don't generate
fixes for rules marked as unfixable.

We often forget to add this, and it leads to bugs in enforcing
`--unfixable`.

This PR instead removes all of these checks, moving the responsibility
of enforcing `--unfixable` up to `check_path`. This is similar to how
@zanieb handled the `--extend-unsafe` logic: we post-process the
diagnostics to remove any fixes that should be ignored.

Promote some rules to "always" fixable (#7840)
## Summary

This PR upgrades some rules from "sometimes" to "always" fixes, now that
we're getting ready to ship support in the CLI. The focus here was on
identifying rules for which the diagnostic itself is high-confidence,
and the fix itself is too (assuming that the diagnostic is correct).
This is _unlike_ rules that _may_ be a false positive, like those that
(e.g.) assume an object is a dictionary when you call `.values()` on it.

Specifically, I upgraded:

- A bunch of rules that only apply to `.pyi` files.
- Rules that rewrite deprecated imports or aliases.
- Some other misc. rules, like: `empty-print-string`, `unused-noqa`,
`getattr-with-constant`.

Open to feedback on any of these.

Rename applicability levels to `Safe`, `Unsafe`, and `Display` (#7843)
After working with the previous change in
https://github.com/astral-sh/ruff/pull/7821 I found the names a bit
unclear and their relationship with the user-facing API muddied. Since
the applicability is exposed to the user directly in our JSON output, I
think it's important that these names align with our configuration
options. I've replaced `Manual` or `Never` with `Display` which captures
our intent for these fixes (only for display). Here, we create room for
future levels, such as `HasPlaceholders`, which wouldn't fit into the
`Always`/`Sometimes`/`Never` levels.

Unlike https://github.com/astral-sh/ruff/pull/7819, this retains the
flat enum structure which is easier to work with.

Rename applicability levels to always, sometimes, and never (#7821)

https://github.com/astral-sh/ruff/discussions/5476, #7769,

this pull request changes `Applicability` from using `Automatic`,
`Suggested`, and `Manual` to `Always`, `Sometimes`, and `Never`.

Also removes `Applicability::Unspecified` (replacing #7792).

Rename `FixKind` to `FixAvailability` (#7658)
**Summary** `FixKind` feels to generic, i suggest renaming it to
something like `FixAvailibility`.

Commands used:

```bash
rg FixKind --files-with-matches | xargs sed -i 's/FixKind/FixAvailability/g'
rg fix_kind --files-with-matches | xargs sed -i 's/fix_kind/fix_availability/g'
rg FIX_KIND --files-with-matches | xargs sed -i 's/FIX_KIND/FIX_AVAILABILITY/g'
cargo fmt
```

`rg -i "fix.kind"` doesn't show any matches anymore.

Add `Expr::Name` checks to rules which use `is_logger_candidate` (#7521)
## Summary

Expands several rules to also check for `Expr::Name` values. As they
would previously not consider:
```python
from logging import error

error("foo")
```
as potential violations
```python
import logging

logging.error("foo")
```
as potential violations leading to inconsistent behaviour. 

The rules impacted are:

- `BLE001`
- `TRY400`
- `TRY401`
- `PLE1205`
- `PLE1206`
- `LOG007`
- `G001`-`G004`
- `G101`
- `G201`
- `G202`

## Test Plan

Fixtures for all impacted rules expanded.

Introduce `LinterSettings`
## Stack Summary

This stack splits `Settings` into `FormatterSettings` and `LinterSettings` and moves it into `ruff_workspace`. This change is necessary to add the `FormatterSettings` to `Settings` without adding `ruff_python_formatter` as a dependency to `ruff_linter` (and the linter should not contain the formatter settings). 

A quick overview of our settings struct at play:

* `Options`: 1:1 representation of the options in the `pyproject.toml` or `ruff.toml`.  Used for deserialization.
* `Configuration`: Resolved `Options`, potentially merged from multiple configurations (when using `extend`). The representation is very close if not identical to the `Options`.
* `Settings`: The resolved configuration that uses a data format optimized for reading. Optional fields are initialized with their default values. Initialized by `Configuration::into_settings` .

The goal of this stack is to split `Settings` into tool-specific resolved `Settings` that are independent of each other. This comes at the advantage that the individual crates don't need to know anything about the other tools. The downside is that information gets duplicated between `Settings`. Right now the duplication is minimal (`line-length`, `tab-width`) but we may need to come up with a solution if more expensive data needs sharing.

This stack focuses on `Settings`. Splitting `Configuration` into some smaller structs is something I'll follow up on later. 

## PR Summary

This PR extracts the linter-specific settings into a new `LinterSettings` struct and adds it as a `linter` field to the `Settings` struct. This is in preparation for moving `Settings` from `ruff_linter` to `ruff_workspace`
