#29450 [NEW]: massive memmory problem in domxml_open_mem

From: bo at theaddedones dot com Operating system: MAC OS X, AMD Altholon, SOLARIS PHP version: 4.3.8 PHP Bug Type: DOM XML related Bug description: massive memmory problem in domxml_open_mem Description: ------------ I know this issue has been resolved in PHP 5.0 using DomDocument::loadXML, BUT in non 5.0 versions, the loading of string XML (memmory) bits has some serious garbage collection problems...namely repeated calls to domxml_open_mem eats the memmory of the system alive.... unsetting variables has no effect.... Reproduce code: --------------- $tt = '<?xml version="1.0" encoding="ISO-8859-1"?> <data> <ff> <rrr>555</rrr> <rrrr>5555</rrrr> <rrrrr>55555</rrrrr> <rrrrrr>555555</rrrrrr> <rrrrrrr>5555555</rrrrrrr> <rrrrrrrr>55555555</rrrrrrrr> <rrrrrrrrr>555555555</rrrrrrrrr> </ff> </data>'; for($i=0;$i<100000;$i++){ $dd = domxml_open_mem($tt); unset($dd); } Expected result: ---------------- not to have the system memory jump by Megabytes...if the loop is left for longer it will eventually chew all resources Actual result: -------------- massive eating of memmory -- Edit bug report at http://bugs.php.net/?id=29450&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=29450&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=29450&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=29450&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=29450&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=29450&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=29450&r=needscript Try newer version: http://bugs.php.net/fix.php?id=29450&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=29450&r=support Expected behavior: http://bugs.php.net/fix.php?id=29450&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=29450&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=29450&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=29450&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=29450&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=29450&r=dst IIS Stability: http://bugs.php.net/fix.php?id=29450&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=29450&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=29450&r=float
