Bug #79289 [NEW]: POSTing a CurlFile causes timeout

From: anton dot gardalv at winlas dot se Operating system: Windows PHP version: 7.4.2 Package: cURL related Bug Type: Bug Bug description:POSTing a CurlFile causes timeout Description: ------------ Hello, after upgrading some of our environments to PHP 7.4 we've noticed that POSTing a CurlFile via CURLOPT_POSTFIELDS seems to cause a timeout. The test script works fine in PHP 7.3 but times out in 7.4. Test script: --------------- <?php $curl = curl_init(); curl_setopt_array($curl, array( CURLOPT_URL => "http://localhost/testpost.php", CURLOPT_RETURNTRANSFER => true, CURLOPT_SSL_VERIFYHOST => 0, CURLOPT_SSL_VERIFYPEER => 0, CURLOPT_TIMEOUT => 25, CURLOPT_FOLLOWLOCATION => false, CURLOPT_CUSTOMREQUEST => "POST", CURLOPT_POSTFIELDS => array('file'=> new CURLFILE('C:/test.txt')), )); $response = curl_exec($curl); var_dump($response); curl_close($curl); ?> TestPost.php <?php var_dump($_POST); var_dump($_FILES); ?> Expected result: ---------------- A reply from the TestPost.php script containing information about the file I sent earlier. Actual result: -------------- PHP/Curl times out. -- Edit bug report at https://bugs.php.net/bug.php?id=79289&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=79289&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=79289&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=79289&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=79289&r=needscript Try newer version: https://bugs.php.net/fix.php?id=79289&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=79289&r=support Expected behavior: https://bugs.php.net/fix.php?id=79289&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=79289&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=79289&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=79289&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=79289&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=79289&r=dst IIS Stability: https://bugs.php.net/fix.php?id=79289&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=79289&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=79289&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=79289&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=79289&r=mysqlcfg
