## Summary
The existing signature for `str` calls had various problems, one of
which I noticed while looking at some ecosystem projects (`scrapy`,
added as a project to mypy_primer in this PR).
## Test Plan
- New tests for `str(…)` calls.
- Observed reduction of false positives in ecosystem checks
## Summary
This PR adds a CI job that causes GitHub to add annotations to a PR diff
when mdtest assertions fail. For example:
<details>
<summary>Screenshot</summary>
</details>
## Motivation
Debugging mdtest failures locally is currently a really nice experience:
- Errors are displayed with pretty colours, which makes them much more
readable
- If you run the test from inside an IDE, you can CTRL-click on a path
and jump directly to the line that had the failing assertion
- If you use
[`mdtest.py`](https://github.com/astral-sh/ruff/blob/main/crates/red_knot_python_semantic/mdtest.py),
you don't even need to recompile anything after changing an assertion in
an mdtest, amd the test results instantly live-update with each change
to the MarkDown file
Debugging mdtest failures in CI is much more unpleasant, however.
Sometimes an error message is just
> [static-assert-error] Argument evaluates to `False`
...which doesn't tell you very much unless you navigate to the line in
question that has the failing mdtest assertion. The line in question
might not even be touched by the PR, and even if it is, it can be hard
to find the line if the PR touches many files. Unlike locally, you can't
click on the error and jump straight to the line that contains the
failing assertion. You also don't get colourised output in CI
(https://github.com/astral-sh/ruff/issues/13939).
GitHub PR annotations should make it really easy to debug why mdtests
are failing on PRs, making PR review much easier.
## Test Plan
I opened a PR to my fork
[here](https://github.com/AlexWaygood/ruff/pull/11/files) with some
bogus changes to an mdtest to show what it looks like when there are
failures in CI and this job has been added. Scroll down to
`crates/red_knot_python_semantic/resources/mdtest/type_properties/is_equivalent_to.md`
on the "files changed" tab for that PR to see the annotations.

Installing pre-commit via pip can take up to 6s sometimes in CI (e.g.
3961179597).
Installing pre-commit via uv should be faster. It also simplifies the
workflow and improves the amount we're dogfooding our own tools
Following
29573daef5,
it doesn't look to me like any of the pre-commit hooks run in CI here
are Rust-based:
- `cargo fmt` is Rust-based but it's explicitly skipped as part of this
job and run as a separate CI job:
93052331b0/.pre-commit-config.yaml (L124-L125)
- The `typos` hook is Rust-based, but according to
https://github.com/crate-ci/typos/blob/master/docs/pre-commit.md
pre-commit should install a built binary rather than building the binary
from source
As such, I think this step in the workflow is just taking up 15s of CI
time and not actually speeding up pre-commit at all
## Summary
Move the mypy_primer build to the depot runners to speed them up.
## Test Plan
Previous run of mypy_primer: 3m 49s
Run on this branch: 1m 38s
## Summary
Use a debug build instead of a release build in order to speed up
mypy_primer runs.
## Test Plan
Previous mypy_primer run: 5m 45s
mypy_primer run on this branch: 3m 49s
This is a well-typed codebase on which we only emit 23 diagnostics right
now, but which is highlighting some interesting issues. It uses some
modern syntactic features such as `match` statements that aren't used
much in other open-source projects in mypy_primer
## Summary
Return the revealed-type from the monkey-patched `revale_type`
implementation to
preserve the identity behavior.
This PR also isolates different script runs by assigning a different
`globals` dict for each script-run. See

`base.sha` appears to be the commit of the base branch when the pull
request was opened, not the base commit that's used to construct the
test merge commit — which can lead to incorrect "determine changes"
results where commits made to the base ref since the pull request are
opened are included in the results.
We use `git merge-base` to find the correct sha, as I don't think that
GitHub provides this. They provide `merge_commit_sha` but my
understanding is that is equivalent to the actual merge commit we're
testing in CI.
I tested this locally on an example pull request. I don't think it's
worth trying to reproduce a specific situation here.

## Summary
This PR adds a playground for Red Knot
[Screencast from 2024-08-14
10-33-54.webm](https://github.com/user-attachments/assets/ae81d85f-74a3-4ba6-bb61-4a871b622f05)
Sharing does work 😆 I just forgot to start wrangler.
It supports:
* Multiple files
* Showing the AST
* Showing the tokens
* Sharing
* Persistence to local storage
Future extensions:
* Configuration support: The `pyproject.toml` would *just* be another
file.
* Showing type information on hover
## Blockers
~~Salsa uses `catch_unwind` to break cycles, which Red Knot uses
extensively when inferring types in the standard library.
However, WASM (at least `wasm32-unknown-unknown`) doesn't support
`catch_unwind` today, so the playground always crashes when the type
inference encounters a cycle.~~
~~I created a discussion in the [salsa
zulip](https://salsa.zulipchat.com/#narrow/stream/333573-salsa-3.2E0/topic/WASM.20support)
to see if it would be possible to **not** use catch unwind to break
cycles.~~
~~[Rust tracking issue for WASM catch unwind
support](https://github.com/rust-lang/rust/issues/118168)~~
~~I tried to build the WASM with the nightly compiler option but ran
into problems because wasm-bindgen doesn't support WASM-exceptions. We
could try to write the binding code by hand.~~
~~Another alternative is to use `wasm32-unknown-emscripten` but it's
rather painful to build~~
## Summary
This is prep-work for the Red Knot playground. We'll have two
playgrounds, one for Red Knot and Ruff.
I want to share some components between the two, a "shared" NPM package
in a local workspace is a great fit for that.
I also want to share the dev dependencies and dev scripts. Again, NPM
workspaces are great for that.
This PR also sets up a CI workflow for the playground to prevent
surprises during the release.
## Test Plan
CI, local `npm install`, `npm start`, ...
I verified that the new CI step fails if there's a typescript or
formatting error.
* [Deployment test
run](3890552435)
## Summary
The PPC64le wheel testing job spuriously failes due to some race when
installing python dependencies.
This is very annoying because it requires restarting the release process
over and over again until you're lucky and it passes.
This PR disables wheel testing on PPC64le
This is the same as we did in uv, see
https://github.com/astral-sh/uv/issues/11231
## Test Plan
The wheel test step was skipped in CI, see
3887406516
but it still runs for other targets
## Summary
Use bash and `git diff` to determine which steps need to run.
We previously used the `changed-files` github actions but using `git`
directly seems simple enough.
All credit for the bash magic goes to @zanieb and @geofft. All I did was
replace the paths arguments.
## Test Plan
* [Linter only change](https://github.com/astral-sh/ruff/pull/16800):
See how the fuzzer and formatter steps, and the linter ecosystem checks
are skipped
* [Formatter only change](https://github.com/astral-sh/ruff/pull/16799):
See how the fuzzer and linter ecosystem checks are skipped

SemVer version).

The ecosystem checks have proven useful so far, so I'm extending the
list a bit. My main selection criteria are:
- Few dependencies (we don't understand -stubs/-types packages yet)
- Fewer than 1000 diagnostics
- No panics
## Test Plan
Ran it locally. We now have ~2k diagnostics in total, across 12 projects
## Summary
I noticed that the pipeline can succeed if there are problems with tool
installation or dependency resolution. This change makes sure that the
pipeline fails in these cases.
## Summary
Add a new pipeline to comment on PRs if there is a mypy_primer diff
result.
## Test Plan
Not yet, I'm afraid I will have to merge this first to have the pipeline
available on main.
## Summary
Run Red Knot on a small selection of ecosystem projects via a forked
version of `mypy_primer`.
Fork: https://github.com/astral-sh/mypy_primer
Branch: add-red-knot-support
## Test Plan
* Successful run:
3839024555
* Intentially failed run where I commented out `unresolved-attribute`
diagnostics reporting:
3838522414
