fix: VFS should not walk circular symlinks As of #6246, rust-analyzer follows symlinks. This can introduce an infinite loop if symlinks point to parent directories. Considering that #6246 was added in 2020 without many bug reports, this is clearly a rare occurrence. However, I am observing rust-analyzer hang on projects that have symlinks of the form: ``` test/a_symlink -> ../../ ``` Ignore symlinks that only point to the parent directories, as this is more robust but still allows typical symlink usage patterns.
rust-analyzer is a modular compiler frontend for the Rust language. It is a part of a larger rls-2.0 effort to create excellent IDE support for Rust.
