#41479 [NEW]: Memory Leaks when creating a DOMDocument

From: cmmtch at rit dot edu Operating system: SunOS 5.10 sparc PHP version: 5.2.2 PHP Bug Type: DOM XML related Bug description: Memory Leaks when creating a DOMDocument Description: ------------ Every time you create a new DOMDocument, even if you unset it directly afterwards, a small amount of memory is leaked. Reproduce code: --------------- <?php while(true){ $doc = new DOMDocument(); unset($doc); } ?> Expected result: ---------------- Check the memory usage after a few seconds and notice it will go up dramatically. Actual result: -------------- When checking how much memory is used by this process, it will go up with time, even though no variables are being left unset. This means that every time a new DOMDocument is constructed, it allocates more memory than it's destructor is handling. This can be very bad when creating lots of DOMDocuments within a single process. -- Edit bug report at http://bugs.php.net/?id=41479&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=41479&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=41479&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=41479&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=41479&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=41479&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=41479&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=41479&r=needscript Try newer version: http://bugs.php.net/fix.php?id=41479&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=41479&r=support Expected behavior: http://bugs.php.net/fix.php?id=41479&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=41479&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=41479&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=41479&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=41479&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=41479&r=dst IIS Stability: http://bugs.php.net/fix.php?id=41479&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=41479&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=41479&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=41479&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=41479&r=mysqlcfg
