From: Operating system: Windows Server 2008 PHP version: 5.3.6 Package: Directory function related Bug Type: Bug Bug description:GetSize() returns negative values for large file sizes Description: ------------ When using GetFile() as documented http://php.net/manual/en/directoryiterator.getsize.php if you run the function on a large file you get negative values which are wrong. I haven't got the exact file size that this happens at, but I have tested with files of 7GB and over, and always get the same result. tested using the function in the test script. Test script: --------------- function dirSize($directory) { $size = 0; foreach(new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory)) as $file){ $size+=$file->getSize(); } return $size; } Then ran function using input value of a directory with a single file of 8,510,398,464 bytes in size. Expected result: ---------------- 8310936 KB Actual result: -------------- -77674.63 -- Edit bug report at http://bugs.php.net/bug.php?id=54758&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=54758&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=54758&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=54758&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=54758&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=54758&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=54758&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=54758&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=54758&r=needscript Try newer version: http://bugs.php.net/fix.php?id=54758&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=54758&r=support Expected behavior: http://bugs.php.net/fix.php?id=54758&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=54758&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=54758&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=54758&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=54758&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=54758&r=dst IIS Stability: http://bugs.php.net/fix.php?id=54758&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=54758&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=54758&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=54758&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=54758&r=mysqlcfg
