Bug description

I was going through the practice exercise3 and noticed the following

• if I create and use a virtual environment using Python 3.9, it finds both findings when I run pyre analyze --verify
• if I create and use a virtual environment using Python 3.12, it finds one findings (the eval) when I run pyre analyze --verify
• if I create and use a virtual environment using Python 3.13, it finds no findings when I run pyre analyze --verify

In the exercise, we have two sinks:

• eval
• exec

and we have the following in the predefined rce_sinks.pysa:

def eval(__source: TaintSink[RemoteCodeExecution], __globals, __locals): ...
if sys.version >= (3, 11, 0):
    def exec(__source: TaintSink[RemoteCodeExecution], __globals, __locals, *, closure): ...
else:
    def exec(__source: TaintSink[RemoteCodeExecution], __globals, __locals): ...

so they should both be detected, even on Python versions higher than 3.11

On 3.12, I would see the following in the output which means that it didn't match def exec and claims that there is a signature mismatch:

ƛ  /tmp/pyre-check/documentation/pysa_tutorial/exercise3/../../../stubs/taint/core_privacy_security/rce_sinks.pysa:4: Model signature parameters for `exec` do not match implementation `def exec(unknown, globals: dict[str, Any] | None = ..., locals: Mapping[str, object] | None = ..., closure: tuple[CellType, ...] | None = ...) -> None: ...`. Reasons:
ƛ unexpected named parameter: `__locals`
ƛ unexpected named parameter: `__globals`
ƛ unexpected named parameter: `__source`

Running:

>>> import inspect
>>> inspect.signature(exec)
<Signature (source, /, globals=None, locals=None, *, closure=None)>

shows that the signature hasn't changed, but for some reason, pyre thinks that it has.

On 3.13, it did this both for exec and eval

ƛ  /tmp/pyre-check/documentation/pysa_tutorial/exercise3/../../../stubs/taint/core_privacy_security/rce_sinks.pysa:2: Model signature parameters for `eval` do not match implementation `def eval(unknown, globals: dict[str, Any] | None = ..., locals: Mapping[str, object] | None = ...) -> Any: ...`. Reasons:
ƛ unexpected positional only parameter: `__locals` at position: 2, expected position 0
ƛ unexpected positional only parameter: `__globals` at position: 1, expected position 0
ƛ  /tmp/pyre-check/documentation/pysa_tutorial/exercise3/../../../stubs/taint/core_privacy_security/rce_sinks.pysa:4: Model signature parameters for `exec` do not match implementation `def exec(unknown, globals: dict[str, Any] | None = ..., locals: Mapping[str, object] | None = ..., closure: tuple[CellType, ...] | None = ...) -> None: ...`. Reasons:
ƛ unexpected named parameter: `__locals`
ƛ unexpected named parameter: `__globals`
ƛ unexpected named parameter: `__source`

Again, looking at the signature shows that it hasn't changed:

>>> inspect.signature(eval)
<Signature (source, /, globals=None, locals=None)>

but pyre thinks that it has for some reason. Any ideas? Thanks

Hi @ossie-git, thanks for reaching out.

I was able to reproduce the problem, using the uv tool, which is quite convenient:

$ uvx --python 3.10 --with fb-sapp --with django-stubs --from pyre-check pyre -n analyze --no-verify
# 2 issues
$ uvx --python 3.12 --with fb-sapp --with django-stubs --from pyre-check pyre -n analyze --no-verify
# 1 issue
$ uvx --python 3.13 --with fb-sapp --with django-stubs --from pyre-check pyre -n analyze --no-verify

The problem is indeed in our taint stubs. I have a fix internally, we should be able to merge that in master pretty quickly. Once that is merged and the issue is closed, you should be able to use the pyre-check-nightly package instead of pyre-check, until we push a new release.

Thanks @arthaud. Given that this might have resulted in CI/CD pipelines and normal users running pysa missing findings, would it be possible to have these types of errors (signature mismatches) result in pysa failing with a non-zero exit code instead of continuing? A possible option would be to add a command line switch which would allow users to override this. Just a suggestion. Thanks

[arthaud]

You should get an error if you are running without --no-verify. The problem is that you would also get unrelated errors, related to missing stubs. We would definitely want to improve this, but have higher priority work, unfortunately.
