#48207 [Opn->Fbk]: CURLOPT_FILE behaves unexpectedly with invalid file handle

ID: 48207 Updated by: jani@php.net Reported By: mark at dynom dot nl -Status: Open +Status: Feedback Bug Type: cURL related Operating System: Linux PHP Version: 5.3.0RC2 New Comment: Please try using this CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows: http://windows.php.net/snapshots/ Previous Comments: ------------------------------------------------------------------------ [2009-05-09 14:03:57] mark at dynom dot nl Sorry, the expected result is not 'works', it's an error being raised. ------------------------------------------------------------------------ [2009-05-09 14:01:55] mark at dynom dot nl Description: ------------ The option 'CURLOPT_FILE' takes a file handle as argument, however when you open the file read-only. cURL *silently* fails and downloads only 1 successful iteration of data. This *only* happens when CURLOPT_RETURNTRANSFER is not defined, since that disables the 'CURLOPT_FILE' feature. It's expected that some sort of warning/error is raised, just like when a write flag is set when the file is not writable. When the latter happens, cURL falls back on CURLOPT_RETURNTRANSFER = false. Reproduce code: --------------- <?php error_reporting( E_ALL ); $ch = curl_init('http://kernel.org/pub/linux/kernel/v1.0/linux-1.0.tar.bz2'); $fp = fopen("/tmp/fubar", "r"); // Opening 'fubar' with the incorrect readonly flag curl_setopt($ch, CURLOPT_FILE, $fp); curl_exec($ch); // Debug $info = curl_getinfo($ch); if ($info['size_download'] !== $info["download_content_length"]) { echo 'fail'; } else { echo 'works'; } curl_close($ch); Expected result: ---------------- works Actual result: -------------- fail ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=48207&edit=1
