Bug #63859 [NEW]: Memory leak when reusing curl-handle

From: jille at hexon dot cx Operating system: Linux PHP version: 5.4.10 Package: cURL related Bug Type: Bug Bug description:Memory leak when reusing curl-handle Description: ------------ PHP (or libcurl, I'm afraid I don't know where exactly the problem lies) seems to leak memory when using the same curl-handle for multiple requests. The test script below reports the same memory_get_usage()-value for the first 300 requests and a 25% increase after but top(1) reports the memory grows up to 100MB when the script is done. Uncommenting the resetting of CURLOPT_POSTFIELDS doesn't seem to help. Uncommenting the recreation of $ch prevents the memory from being leaked. Test script: --------------- <?php $ch = curl_init('http://some-domain.com/dump.html'); for($i = 0; 1000 > $i; $i++) { # $ch = curl_init('http://some-domain.com/dump.html'); $post = array(); $post['data'] = base64_encode(str_repeat(hash('sha256', uniqid()), 1000)); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $post); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_exec($ch); # curl_setopt($ch, CURLOPT_POSTFIELDS, ''); if($i % 100 == 0) { var_dump(memory_get_usage(true)); } } ?> -- Edit bug report at https://bugs.php.net/bug.php?id=63859&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=63859&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=63859&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=63859&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=63859&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=63859&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=63859&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=63859&r=needscript Try newer version: https://bugs.php.net/fix.php?id=63859&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=63859&r=support Expected behavior: https://bugs.php.net/fix.php?id=63859&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=63859&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=63859&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=63859&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=63859&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=63859&r=dst IIS Stability: https://bugs.php.net/fix.php?id=63859&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=63859&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=63859&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=63859&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=63859&r=mysqlcfg
