`pyo3_init` resulting in a segementation fault
sansyrox opened this issue · comments
Hi,
I am trying to add pyo3-log in my code but it is resulting in a seg fault.
Here is the rust code
mod executors;
mod io_helpers;
mod request_handler;
mod routers;
mod server;
mod shared_socket;
mod types;
mod web_socket_connection;
// use pyo3_log::{Caching, Logger};
use server::Server;
use shared_socket::SocketHeld;
// pyO3 module
use pyo3::prelude::*;
#[pymodule]
pub fn robyn(_py: Python<'_>, m: &PyModule) -> PyResult<()> {
// the pymodule class to make the rustPyFunctions available
pyo3_log::init();
m.add_class::<Server>()?;
m.add_class::<SocketHeld>()?;
pyo3::prepare_freethreaded_python();
Ok(())
}and here is the python code

and I am using maturin as the development system.
Do you happen to know a fix for this?
Hello
No, this is the first time I'm seeing this. It would help if you could minimize the reproducer to something shorter. Also, a stack trace from gdb could shed some light into what's happening. And honestly, segfault is a bit suspicious thing here, as poy3-log has no unsafe code in it ‒ the theory is that it should be impossible to cause it from such code due to Rust safety guarantees and that the problem probably lies somewhere else (or at least part of the problem).
Hi @vorner ,
Thank you for your revert. I was able to isolate the problem to some extent(updated in the description).
However, I am still learning on how to use gdb with python. I will update the trace as soon as I can figure it out.
Just tried out lldb, which is similar to gdb.
But I still got this. I created a simple bash script to run the script with the venv Python.
(lldb) platform shell /Users/bruhh/Desktop/robyn/a.sh
/Users/bruhh/Desktop/robyn/a.sh: line 3: 97612 Segmentation fault: 11 /Users/bruhh/Desktop/robyn/venv/bin/python /Users/bruhh/Desktop/robyn/integration_tests/base_routes.py
error: command returned with status 139Hi @vorner ,
I was unable to debug what was causing the seg fault. But I was able to find a fix to this issue. My repo is using pyo3-0.14.x and the latest version of pyo3-log requires atleast 0.16.0 (correct me if I am wrong).
I fixed it by downgrading pyo3-log.
Let me re-check I understand it correctly. Your program contained two versions of pyo3, using both? If that's the case, then it's something that I wouldn't expect to work and matching the versions is the right solution.
Anyway, the last few versions of pyo3-log differ only in the version of pyo3 they depend on, so you're not missing anything by downgrading (at least, not on the pyo3-log side).

Nope. It only contained one pyo3(0.14.1).

Ah, perfect then! :D
Nope. It only contained one pyo3(0.14.1).
I mean including the indirect dependencies. You depended (directly) on 0.14.1 and pyo3-log depended on 0.16, so it pulled in both into the dep graph.
Do you still have the old version somewhere? Can you do cargo tree on that? (you might need to install it) or attach the Cargo.lock or Cargo.toml here?

That would have been possible.
