Buffers on the edge: Python and Rust

Read Original

This technical article investigates a subtle bug involving data races when Python's buffer protocol (enabling zero-copy memory sharing) interacts with Rust's memory model. It explains how C extensions releasing the GIL can lead to unsynchronized reads/writes, causing undefined behavior, even when individual components are correctly implemented.
