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:
https://github.com/zed-industries/zed/blob/cf7c64d77f1806cdd34b3812bbf27681fb3cb905/crates/util/src/archive.rs#L47
And then gets ignored here:
https://github.com/zed-industries/zed/blob/cf7c64d77f1806cdd34b3812bbf27681fb3cb905/crates/dap/src/adapters.rs#L323-L326
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.
1. Create a simple Rust project. Make sure you use gnu toolchain (target
`x86_64-pc-windows-gnu`)
```rust
fn world() -> String {
"world".into()
}
fn main() {
let w = world();
println!("hello {}", w);
}
```
2. Put a breakpoint on line 7 (`println`)
3. In the command palette choose "debugger: start" and then select "run
*crate name*"
