o gallery-dl falhou

Error message

o gallery-dl falhou: {}

What it means

download() treats the run as failed only when gallery-dl exited non-success AND no files were collected from stdout; in that case it throws this error with the stderr log tail as detail. If any files were produced, partial success is accepted and returned in Downloaded { files, log_tail }.

Solutions

1. Read log_tail in the error for gallery-dl's own diagnostic
2. Refresh cookies if the content is behind login
3. Check free disk space and write permissions on the destination folder
4. Retry with backoff on transient network/rate-limit errors; update gallery-dl if the extractor is outdated

Example fix

// before
let out = gdl::download(&url, &dest, Some(&cookies), limit, &progress).await?;
// after
let out = match gdl::download(&url, &dest, Some(&cookies), limit, &progress).await {
    Ok(o) if o.files.is_empty() && !o.log_tail.contains("403") => o,
    Err(e) if e.to_string().contains("falhou") => {
        refresh_cookies(&mut session)?;
        gdl::download(&url, &dest, Some(&session.cookie_path()), limit, &progress).await?
    }
    other => other?,
};

let free = fs2::available_space(&dest)?;
anyhow::ensure!(free > 100 * 1024 * 1024, "espaço insuficiente em {:?}", dest);

match gdl::download(&url, &dest, cookies, limit, &progress).await {
    Ok(d) => d,
    Err(e) if e.to_string().contains("o gallery-dl falhou") => {
        if is_transient(&e) { retry_with_backoff(3, || gdl::download(&url, &dest, cookies, limit, &progress)).await? }
        else { return Err(e); }
    }
    Err(e) => return Err(e),
}

When it happens

Trigger: gallery-dl exits with non-zero status and zero files were parsed: download aborted early (403, 404, network drop), disk full preventing output, extractor error, or auth rejection.

Common situations: Target media requires cookies that expired; Tumblr post removed/private; disk quota exceeded on dest; rate limiting interrupted the first file; broken extractor after a site layout change.
