Instead of doing this on a lint-by-lint basis, we now just do it right
before rendering. This is more broadly applicable.
Note that this doesn't fix the diagnostic rendering for the Python
parser. But that's using a different path anyway (`annotate-snippets` is
only used in tests).
We do this because `...` is valid Python, which makes it pretty likely
that some line trimming will lead to ambiguous output. So we add support
for overriding the cut indicator. This also requires changing some of
the alignment math, which was previously tightly coupled to `...`.
For Ruff, we go with `…` (`U+2026 HORIZONTAL ELLIPSIS`) for our cut
indicator.
For more details, see the patch sent to upstream:
https://github.com/rust-lang/annotate-snippets-rs/pull/172
These snapshot changes should *all* only be a result of changes to
trailing whitespace in the output. I checked a psuedo random sample of
these, and the whitespace found in the previous snapshots seems to be an
artifact of the rendering and _not_ of the source data. So this seems
like a strict bug fix to me.
There are other snapshots with whitespace changes, but they also have
other changes that we split out into separate commits. Basically, we're
going to do approximately one commit per category of change.
This represents, by far, the biggest chunk of changes to snapshots as a
result of the `annotate-snippets` upgrade.
Previously, we were replacing unprintable ASCII characters with a
printable representation of them via fancier Unicode characters. Since
`annotate-snippets` used to use codepoint offsets, this didn't make our
ranges incorrect: we swapped one codepoint for another.
But now, with the `annotate-snippets` upgrade, we use byte offsets
(which is IMO the correct choice). However, this means our ranges can be
thrown off since an ASCII codepoint is always one byte and a non-ASCII
codepoint is always more than one byte.
Instead of tweaking the `ShowNonprinting` trait and making it more
complicated (which is used in places other than this diagnostic
rendering it seems), we instead change `replace_whitespace` to handle
non-printable characters. This works out because `replace_whitespace`
was already updating the annotation range to account for the tab
replacement. We copy that approach for unprintable characters.
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.
## Summary

## Summary
This PR updates the way syntax errors are handled throughout the linter.
The main change is that it's now not considered as a rule which involves
the following changes:
* Update `Message` to be an enum with two variants - one for diagnostic
message and the other for syntax error message
* Provide methods on the new message enum to query information required
by downstream usages
This means that the syntax errors cannot be hidden / disabled via any
disablement methods. These are:
1. Configuration via `select`, `ignore`, `per-file-ignores`, and their
`extend-*` variants
```console
$ cargo run -- check ~/playground/ruff/src/lsp.py --extend-select=E999
--no-preview --no-cache
Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.10s
Running `target/debug/ruff check /Users/dhruv/playground/ruff/src/lsp.py
--extend-select=E999 --no-preview --no-cache`
warning: Rule `E999` is deprecated and will be removed in a future
release. Syntax errors will always be shown regardless of whether this
rule is selected or not.
/Users/dhruv/playground/ruff/src/lsp.py:1:8: F401 [*] `abc` imported but
unused
|
1 | import abc
| ^^^ F401
2 | from pathlib import Path
3 | import os
|
= help: Remove unused import: `abc`
```
3. Command-line flags via `--select`, `--ignore`, `--per-file-ignores`,
and their `--extend-*` variants
```console
$ cargo run -- check ~/playground/ruff/src/lsp.py --no-cache
--config=~/playground/ruff/pyproject.toml
Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.11s
Running `target/debug/ruff check /Users/dhruv/playground/ruff/src/lsp.py
--no-cache --config=/Users/dhruv/playground/ruff/pyproject.toml`
warning: Rule `E999` is deprecated and will be removed in a future
release. Syntax errors will always be shown regardless of whether this
rule is selected or not.
/Users/dhruv/playground/ruff/src/lsp.py:1:8: F401 [*] `abc` imported but
unused
|
1 | import abc
| ^^^ F401
2 | from pathlib import Path
3 | import os
|
= help: Remove unused import: `abc`
```
This also means that the **output format** needs to be updated:
1. The `code`, `noqa_row`, `url` fields in the JSON output is optional
(`null` for syntax errors)
2. Other formats are changed accordingly
For each format, a new test case specific to syntax errors have been
added. Please refer to the snapshot output for the exact format for
syntax error message.
The output of the `--statistics` flag will have a blank entry for syntax
errors:
```
315 F821 [ ] undefined-name
119 [ ] syntax-error
103 F811 [ ] redefined-while-unused
```
The **language server** is updated to consider the syntax errors by
convert them into LSP diagnostic format separately.
### Preview
There are no quick fixes provided to disable syntax errors. This will
automatically work for `ruff-lsp` because the `noqa_row` field will be
`null` in that case.

## Summary
Implement support for RDJson output for `ruff check`, as requested in
#8655.
## Test Plan
Tested using a snapshot test. Same approach as for e.g. the JSON output
formatter.
## Additional info
I tried to keep the implementation close to the JSON implementation.
I had to deviate a bit to make the `suggestions` key work: If there are
no suggestions, then setting `suggestions` to `null` is invalid
according to the JSONSchema. Therefore, I opted for a slightly more
complex implementation, that skips the `suggestions` key entirely if
there are no fixes available for the given diagnostic. Maybe it would
have been easier to set `"suggestions": []`, but I ended up doing it
this way.
I didn't consider notebooks, as I _think_ that RDJson doesn't work with
notebooks. This should be confirmed, and if so, there should be some
form of warning or error emitted when trying to output diagnostics for a
notebook.
I also didn't consider `ruff format`, as this comment:
https://github.com/astral-sh/ruff/issues/8655#issuecomment-1811446160
suggests that that wouldn't be compatible.
I'm new to Rust, any feedback is appreciated. 🙂 I
implemented this in order to have a productive rainy saturday afternoon,
I'm not knowledgeable about RDJson beyond the sources linked in the
issue.
## Summary
Concurrent GitLab runners clone projects into separate directories, e.g.
`{builds_dir}/$RUNNER_TOKEN_KEY/$CONCURRENT_ID/$NAMESPACE/$PROJECT_NAME`.
Since the fingerprint uses the full path to the file, the fingerprints
calculated by Ruff are different depending on which concurrent runner it
executes on, so often an MR will appear to remove all existing issues
and add them with new fingerprints.
I've adjusted the fingerprint function to use the project relative path,
which fixes this. Unfortunately this will have a breaking change for any
current users of this output - the fingerprints will change and appear
in GitLab as all linting messages having been fixed and then created.
## Test Plan
`cargo nextest run`
Running `ruff check --output-format gitlab` in a git repo, moving the
repo and running again, verifying no diffs between the outputs
## Summary
Adds support for sarif v2.1.0 output to cli, usable via the
output-format paramter.
`ruff . --output-format=sarif`
Includes a few changes I wasn't sure of, namely:
* Adds a few derives for Clone & Copy, which I think could be removed
with a little extra work as well.
## Test Plan
I built and ran this against several large open source projects and
verified that the output sarif was valid, using [Microsoft's SARIF
validator tool](https://sarifweb.azurewebsites.net/Validation)
I've also attached an output of the sarif generated by this version of
ruff on the main branch of django at commit: b287af5dc9
[django_main_b287af5dc9_sarif.json](13626222/django_main_b287af5dc9_sarif.json)
Note: this needs to be regenerated with the latest changes and
confirmed.
## Open Points
[ ] Convert to just using all Rules all the time
[ ] Fix the issue with getting the file URI when compiling for web
assembly
Update to [Rust
1.74](https://blog.rust-lang.org/2023/11/16/Rust-1.74.0.html) and use
the new clippy lints table.
The update itself introduced a new clippy lint about superfluous hashes
in raw strings, which got removed.
I moved our lint config from `rustflags` to the newly stabilized
[workspace.lints](https://doc.rust-lang.org/stable/cargo/reference/workspaces.html#the-lints-table).
One consequence is that we have to `unsafe_code = "warn"` instead of
"forbid" because the latter now actually bans unsafe code:
```
error[E0453]: allow(unsafe_code) incompatible with previous forbid
--> crates/ruff_source_file/src/newlines.rs:62:17
|
62 | #[allow(unsafe_code)]
| ^^^^^^^^^^^ overruled by previous forbid
|
= note: `forbid` lint level was set on command line
```

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.
## Summary
This PR renames the `tab-size` configuration option to `indent-width` to
express that the formatter uses the option to determine the indentation
width AND as tab width.
I first preferred naming the option `tab-width` but then decided to go
with `indent-width` because:
* It aligns with the `indent-style` option
* It would allow us to write a lint rule that asserts that each
indentation uses `indent-width` spaces.
Closes#7643
## Test Plan
Added integration test
## Summary
This PR adds a new `cell` field to the JSON output format which
indicates the Notebook cell this diagnostic (and fix) belongs to. It
also updates the location for the diagnostic and fixes as per the
`NotebookIndex`. It will be used in the VSCode extension to display the
diagnostic in the correct cell.
The diagnostic and edit start and end source locations are translated
for the notebook as per the `NotebookIndex`. The end source location for
an edit needs some special handling.
### Edit end location
To understand this, the following context is required:
1. Visible lines in Jupyter Notebook vs JSON array strings: The newline
is part of the string in the JSON format. This means that if there are 3
visible lines in a cell where the last line is empty then the JSON would
contain 2 strings in the source array, both ending with a newline:
**JSON format:**
```json
[
"# first line\n",
"# second line\n",
]
```
**Notebook view:**
```python
1 # first line
2 # second line
3
```
2. If an edit needs to remove an entire line including the newline, then
the end location would be the start of the next row.
To remove a statement in the following code:
```python
import os
```
The edit would be:
```
start: row 1, col 1
end: row 2, col 1
```
Now, here's where the problem lies. The notebook index doesn't have any
information for row 2 because it doesn't exists in the actual notebook.
The newline was added by Ruff to concatenate the source code and it's
removed before writing back. But, the edit is computed looking at that
newline.
This means that while translating the end location for an edit belong to
a Notebook, we need to check if both the start and end location belongs
to the same cell. If not, then the end location should be the first
character of the next row and if so, translate that back to the last
character of the previous row. Taking the above example, the translated
location for Notebook would be:
```
start: row 1, col 1
end: row 1, col 10
```
## Test Plan
Add test cases for notebook output in the JSON format and update
existing snapshots.
## Summary
This PR refactors the `NotebookIndex` struct to use `OneIndexed` to make
the
intent of the code clearer.
## Test Plan
Update the existing test case and run `cargo test` to verify the change.
- [x] Verify `--diff` output
- [x] Verify the diagnostics output
- [x] Verify `--show-source` output
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.
Rebase of https://github.com/astral-sh/ruff/pull/5119 authored by
@evanrittenhouse with additional refinements.
## Changes
- Adds `--unsafe-fixes` / `--no-unsafe-fixes` flags to `ruff check`
- Violations with unsafe fixes are not shown as fixable unless opted-in
- Fix applicability is respected now
- `Applicability::Never` fixes are no longer applied
- `Applicability::Sometimes` fixes require opt-in
- `Applicability::Always` fixes are unchanged
- Hints for availability of `--unsafe-fixes` added to `ruff check`
output
## Examples
Check hints at hidden unsafe fixes
```
❯ ruff check example.py --no-cache --select F601,W292
example.py:1:14: F601 Dictionary key literal `'a'` repeated
example.py:2:15: W292 [*] No newline at end of file
Found 2 errors.
[*] 1 fixable with the `--fix` option (1 hidden fix can be enabled with the `--unsafe-fixes` option).
```
We could add an indicator for which violations have hidden fixes in the
future.
Check treats unsafe fixes as applicable with opt-in
```
❯ ruff check example.py --no-cache --select F601,W292 --unsafe-fixes
example.py:1:14: F601 [*] Dictionary key literal `'a'` repeated
example.py:2:15: W292 [*] No newline at end of file
Found 2 errors.
[*] 2 fixable with the --fix option.
```
Also can be enabled in the config file
```
❯ cat ruff.toml
unsafe-fixes = true
```
And opted-out per invocation
```
❯ ruff check example.py --no-cache --select F601,W292 --no-unsafe-fixes
example.py:1:14: F601 Dictionary key literal `'a'` repeated
example.py:2:15: W292 [*] No newline at end of file
Found 2 errors.
[*] 1 fixable with the `--fix` option (1 hidden fix can be enabled with the `--unsafe-fixes` option).
```
Diff does not include unsafe fixes
```
❯ ruff check example.py --no-cache --select F601,W292 --diff
--- example.py
+++ example.py

https://github.com/astral-sh/ruff/pull/7790 will improve the diff
messages following this pull request
Similarly, `--fix` and `--fix-only` require the `--unsafe-fixes` flag to
apply unsafe fixes.
