Bug #66151 [NEW]: Memory leak when SOAP fails to process a WSDL file

From: askalski at gmail dot com Operating system: Linux PHP version: 5.4Git-2013-11-22 (Git) Package: SOAP related Bug Type: Bug Bug description:Memory leak when SOAP fails to process a WSDL file Description: ------------ The PHP SOAP module leaks memory when it fails to parse a WSDL file. This leaked memory is not recovered between requests (mod_php). Test script: --------------- Download the following file into your script directory before testing: http://www.paypalobjects.com/wsdl/PayPalSvc.wsdl Do NOT download the dependent .xsd files (if they already exist in your directory, remove them.) The missing .xsd files will cause the WSDL parse failure which is essential to reproducing the memory leak. PHP should be configured as an Apache module (mod_php). <?php $s = new soapclient("PayPalSvc.wsdl"); ?> Request the script many times with curl or Apache Bench. Monitor memory/swap usage. (Be prepared to stop the test before it exhausts all of your memory. This will happen very quickly.) Expected result: ---------------- Apache worker memory usage should stay relatively constant. Actual result: -------------- Because of the leak, memory usage grows rapidly. -- Edit bug report at https://bugs.php.net/bug.php?id=66151&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=66151&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=66151&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=66151&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=66151&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=66151&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=66151&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=66151&r=needscript Try newer version: https://bugs.php.net/fix.php?id=66151&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=66151&r=support Expected behavior: https://bugs.php.net/fix.php?id=66151&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=66151&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=66151&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=66151&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=66151&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=66151&r=dst IIS Stability: https://bugs.php.net/fix.php?id=66151&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=66151&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=66151&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=66151&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=66151&r=mysqlcfg
