From: petrich at tronic-media dot com Operating system: Linux + Windows PHP version: 5.1.4 PHP Bug Type: *General Issues Bug description: Much Memory Usage while copy big files
Description: ------------ Not sure if it's a "bug or a feature", but when copying a 70MB file via PHP's copy() function, the php process will use nearly the same Memory. I found a (closed) Bug Report (#29922) relatet to this Issue (http://bugs.php.net/bug.php?id=29922), it seems to be fixed long time ago, but in PHP 5.1.4 it is not. Testet with PHP 5.1.4 (on Win-XP and Linux) as Apache2 Module. (All extentins disabled + default php.ini-dist settings) This Bug/Feature does'nt occur in php 4.3.3 (Win-XP as Apache2 Module). Reproduce code: --------------- <?php copy('70MB.data','70MB.data.copy'); /* now look at the (linux) top listing for this Process to trace the growing memmory usage */ ?> Expected result: ---------------- Less Memory Usage in the top listing. Actual result: -------------- Much Memory Usage in the top listing. -- Edit bug report at http://bugs.php.net/?id=37577&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=37577&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=37577&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=37577&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=37577&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=37577&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=37577&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=37577&r=needscript Try newer version: http://bugs.php.net/fix.php?id=37577&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=37577&r=support Expected behavior: http://bugs.php.net/fix.php?id=37577&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=37577&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=37577&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=37577&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=37577&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=37577&r=dst IIS Stability: http://bugs.php.net/fix.php?id=37577&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=37577&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=37577&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=37577&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=37577&r=mysqlcfg
