Bug #79019 [NEW]: Copied cURL handles upload empty file

From: cmb Operating system: * PHP version: 7.4Git-2019-12-23 (Git) Package: cURL related Bug Type: Bug Bug description:Copied cURL handles upload empty file Description: ------------ If a cURL handle which has a CURLFile attached as post field is copied via curl_copy_handle(), the file upload can only succeed the first time it is executed; subsequent executions of the handle copies will upload an empty file. The problem is that the current implementation of request #77711 opens the stream and attaches it to the cURL handle; on the first upload the stream is completely read, but not rewound afterwards (what is not generally possible, anyway), so subsequent uploads only see an empty stream.
