Download cancelled

Error message

Download cancelled

What it means

The gallery-dl wrapper spawns the gallery-dl process and selects between child.wait() and the cancel token's cancelled() future. On cancellation it kills the child, drains stdout/stderr tasks, and bails with 'Download cancelled'.

Solutions

1. Treat as expected abort: catch the error, report partial files already written, and clean temp dirs.
2. If pausing is intended, add a pause mechanism instead of cancelling the token.
3. Avoid sharing one cancel token across unrelated downloads if only one should stop.

if opts.cancel_token.is_cancelled() {
    return Err(anyhow!("Download cancelled")); // skip spawning gallery-dl
}

match download(url, opts).await {
    Err(e) if e.to_string() == "Download cancelled" => {
        cleanup_partial_output(&out_dir);
    }
    other => other?,
}

When it happens

Trigger: Signalling opts.cancel_token while a gallery-dl child process is running (waiting for it to exit); calling download and cancelling before the process finishes.

Common situations: User aborts a gallery-based download mid-run; app shutdown cancels all tokens; UI timeout cancels a slow gallery-dl fetch.
