fix(sqlite): produce correct error for surrogate characters by ever0de · Pull Request #5962 · RustPython/RustPython

Walkthrough

The internal implementation of the str_to_ptr_len function in stdlib/src/sqlite.rs was updated to use try_to_str(vm) for UTF-8 string extraction from PyStr, improving error handling by leveraging the VM's result system. Variable names were adjusted to prevent shadowing, with no changes to public interfaces.

Changes

File(s) Change Summary
stdlib/src/sqlite.rs Updated str_to_ptr_len to use try_to_str(vm) for string extraction and improved error handling; renamed variables to avoid shadowing.

Poem

A string now checked with greater care,
Errors caught in the VM's lair.
No shadows cast on names anew,
SQLite's code now strong and true.

2967-2973: LGTM! Improved error handling for surrogate characters.

The change from s.to_str() to s.try_to_str(vm) properly integrates UTF-8 validation with the VM's error handling system. This will produce more appropriate error messages when encountering invalid UTF-8 sequences like surrogate characters, directly addressing the PR objective. The variable renaming from s to s_str also prevents shadowing and improves code clarity.
