Download already in progress for model: {}

Error message

Download already in progress for model: {}

What it means

download_model checks the active_downloads set at entry and rejects a second concurrent download of the same model name. This prevents two HTTP streams writing the same ggml-<name>.bin path simultaneously. The first download continues unaffected; the duplicate call fails immediately.

Solutions

1. Wait for the in-flight download — subscribe to its progress events until 100 or completion
2. Disable the Download button while the model shows Downloading status
3. If the flag is stale because a prior call hung, cancel the download or restart the app, then retry

Example fix

// before
button.onClick(() => invoke('download_model', { modelName })); // double-fire

// after
let downloading = false;
button.onClick(async () => {
  if (downloading) return;
  downloading = true;
  try { await invoke('download_model', { modelName }); }
  finally { downloading = false; }
});

const models = await invoke<ModelInfo[]>('get_whisper_models');
const downloading = models.find(x => x.name === modelName)?.status === 'Downloading';
if (downloading) {
  // attach to the existing progress stream instead of starting a second one
  return;
}
await invoke('download_model', { modelName });

const isDownloading = (m: ModelInfo | undefined): boolean => m?.status === 'Downloading';

try {
  await invoke('download_model', { modelName });
} catch (e) {
  if (String(e).includes('already in progress')) {
    // benign: join the existing download's progress events
  } else { throw e; }
}

When it happens

Trigger: Double-clicking the Download button before it disables; two UI components both invoking download_model for the same name; automatic retry logic firing while the first attempt still streams.

Common situations: Missing debounce on the download button; background auto-download racing a user-initiated download; optimistic-refresh frontend that re-issues the call.
