ghostscript nao iniciou

Error message

ghostscript nao iniciou: {}

What it means

This error is thrown in run_ghostscript when the tokio async child-process spawn of the Ghostscript executable fails, i.e. `.output()` returns Err before gs even runs. It wraps the underlying io::Error (typically NotFound for a missing binary, or permission/exec issues). It is a pre-execution failure, distinct from Ghostscript running but producing no output.

Solutions

1. Install Ghostscript (apt install ghostscript / brew install ghostscript / choco install ghostscript) and ensure it is on PATH
2. Verify the resolved gs path manually: run `<gs_path> --version`; fix find_gs detection or the PATH if it fails
3. Check the binary is executable (chmod +x / reinstall); confirm no AV policy blocks spawning it
4. If you don't need Ghostscript, switch the repair mode to "rebuild" which does not use gs

Example fix

// before
let gs = super::pdf::find_gs().await.unwrap(); // panics or passes stale path
// after
let gs = match super::pdf::find_gs().await {
    Some(p) if std::process::Command::new(&p).arg("--version").output().is_ok() => p,
    _ => return Err(anyhow!("Ghostscript não encontrado ou não executável")),
};

// Rust: check the gs binary is spawnable before requesting mode "gs"
let ok = match super::pdf::find_gs().await {
    Some(p) => tokio::process::Command::new(&p).arg("--version").output().await.is_ok(),
    None => false,
};
if !ok { anyhow::bail!("Ghostscript indisponível; use mode=\"rebuild\""); }

fn gs_spawnable(path: &std::path::Path) -> bool {
    path.is_file() && std::process::Command::new(path).arg("--version").output().map(|o| o.status.success()).unwrap_or(false)
}

match run(opts, progress).await {
    Err(e) if e.to_string().contains("ghostscript nao iniciou") => {
        // fall back to mode "rebuild" (no Ghostscript needed)
        opts.mode = "rebuild".into();
        run(opts, progress).await
    }
    other => other,
}

When it happens

Trigger: Calling pdf_repair with mode "gs" (or a mode that reaches run_ghostscript) where the path resolved by super::pdf::find_gs() is stale or not executable; the gs binary was uninstalled or moved after detection; PATH lookup fails at spawn time; OS-level exec permission denied.

Common situations: Ghostscript not installed; gs installed under a name/path find_gs does not check (e.g. Windows gswin64c vs gs); a broken symlink; antivirus blocking execution; running in a container image without ghostscript package.
