util: Fix zip extraction by vasyl-protsiv · Pull Request #42714 · zed-industries/zed

I was trying to use Zed for Rust debugging on windows, but was getting this warning in debugger console: "Could not initialize Python interpreter - some features will be unavailable (e.g. debug visualizers)."
As the warning suggests this led to bad debugging experience where the variables were not visualized properly in the "Variables" panel.

After some investigation I found that the problem is that Zed silently failed to extract all files from the debug adapter package (https://github.com/vadimcn/codelldb/releases/download/v1.11.8/codelldb-win32-x64.vsix). Particularly python-lldb folder was missing, which caused the warning.
The error occurred here:

zed/crates/util/src/archive.rs

Line 47 in cf7c64d

reader = item.skip().await.context("reading next zip entry")?;

And then gets ignored here:

zed/crates/dap/src/adapters.rs

Lines 323 to 326 in cf7c64d

    
           extract_zip(&version_path, file) 
        
               .await 
        
               // we cannot check the status as some adapter include files with names that trigger `Illegal byte sequence` 
        
               .ok();

The simple fix is to update async_zip crate to version 0.0.18 where this issue appears to be fixed. I also added logging instead of silently ignoring the error, as I believe that would have helped to catch it earlier.

To reproduce the original issue you can try to follow these steps:
0. (Optional) Remove/rename old codelldb adapter at %localappdata%\Zed\debug_adapters\CodeLLDB. Restart Zed.

Create a simple Rust project. Make sure you use gnu toolchain (target x86_64-pc-windows-gnu)

fn world() -> String {
    "world".into()
}

fn main() {
    let w = world();
    println!("hello {}", w);
}

Put a breakpoint on line 7 (println)
In the command palette choose "debugger: start" and then select "run crate name"
