Panic over `libarchive_seek_callback` when using compress-tools with tokio

[YaxinCheng]

I am trying to list content from this
test.zip. However, it gives me error like this

internal error: entered unreachable code: We need to use libarchive_seek_callback() underlying.
thread 'tokio-runtime-worker' panicked at 'internal error: entered unreachable code: We need to use libarchive_seek_callback() underlying.'

Here is my Cargo.toml and code

#Cargo.toml

[dependencies]
compress-tools = { version = "0.14", features = ["tokio_support"] }
tokio = { version = "1", features = ["macros", "rt-multi-thread"] }

#[tokio::test]
async fn test_list() -> Result<()> {
    let test_zip = concat!(env!("CARGO_MANIFEST_DIR"), "/test_resources/test.zip");
    let zip_file = File::open(test_zip).await?;
    let content = compress_tools::tokio_support::list_archive_files(zip_file).await?;
    println!("content={:?}", content);
    Ok(())
}

Environment:

• OS: macOS 13.1
• libarchive: 3.6.2 (installed from brew)

Any help is appreciated

Thanks for reporting this. I added a draft PR (#97) which adds the integration tests to trigger the error.

The panic happens inside the common async code. Unfortunately, it lacks the real Seek implementation for the wrapper, so we see the error. Would you be willing to look at it?

The PR looks right. Thanks.

Would it be possible to fix this bug? I am not quite sure about the Seek implementation or the feasibility of implementing it
