openclaw - 💡(How to fix) Fix Bug: WhatsApp encrypted media temp files not cleaned up on failure [1 participants]

const fs = require('fs');
const os = require('os');
const path = require('path');
const { promisify } = require('util');
const mkdtemp = promisify(require('fs').mkdtemp);

// Create a temporary directory
async function createTempDir() {
  const tempDir = await mkdtemp(path.join(os.tmpdir(), 'whatsapp-media-'));
  return tempDir;
}

// Create a temporary file with exclusive creation
async function createTempFile(tempDir) {
  const tempFilePath = path.join(tempDir, `media-${generateMessageIDV2()}`);
  await promisify(fs.open)(tempFilePath, 'w', 0o600);
  return tempFilePath;
}

// Example usage
async function encryptedStream() {
  const tempDir = await createTempDir();
  try {
    const encFilePath = await createTempFile(tempDir);
    const originalFilePath = await createTempFile(tempDir);
    // Upload media files
  } finally {
    // Cleanup temporary files and directory
    await promisify(fs.rm)(tempDir, { recursive: true, force: true });
  }
