#48643 [NEW]: Memory not freed with FilterIterator

From: zoe@php.net Operating system: Linux (Ubuntu) PHP version: 5.2CVS-2009-06-22 (CVS) PHP Bug Type: SPL related Bug description: Memory not freed with FilterIterator Description: ------------ An excessive about of memory is used when a class which extends FilterIterator is used to filter for certain file types when scanning a source tree. Reproduce code: --------------- A small benchmark is provided in the tar file here:http://filebin.ca/okgvtt/memcheck.tar The file contains three tests which all use code in Util.php. To run the tests edit the shell script memcheck to add the top level directory of a PHP source tree as input to each test. Then just execute the shell script. The benchmarks produce a list of directories which contain .phpt files, the memory usage when the class PhptFilterIterator is used is 20 times higher than the other two methods. Expected result: ---------------- Would expect the memory usage to be similar. Actual result: -------------- Memory usage is 20 times higher. -- Edit bug report at http://bugs.php.net/?id=48643&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=48643&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=48643&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=48643&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=48643&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=48643&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=48643&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=48643&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=48643&r=needscript Try newer version: http://bugs.php.net/fix.php?id=48643&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=48643&r=support Expected behavior: http://bugs.php.net/fix.php?id=48643&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=48643&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=48643&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=48643&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=48643&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=48643&r=dst IIS Stability: http://bugs.php.net/fix.php?id=48643&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=48643&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=48643&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=48643&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=48643&r=mysqlcfg
