#32095 [Com]: file_exists() doesn't work with 2G+ files

ID: 32095 Comment by: steffen dot ryll at siemens dot com Reported By: david at giffin dot org Status: No Feedback Bug Type: Filesystem function related Operating System: Linux Debian PHP Version: 5.0.1 New Comment: This bug report describes the effect mentioned by "hiro at arkusa dot com" on http://www.php.net/manual/en/function.file-exists.php. The Problem is, that file_exists($NameOfSomeLargeFile) returns false, if $NameOfSomeLargeFile exists *but is larger than 2 GB*. In my case, I have backup.tar.gz with size of 6.6 GB. I expect file_exists("backup.tar.gz") to return true, but it returns false. System: Solaris 10 on SPARCv9, Apache/2.0.52 (Unix) DAV/2 PHP/5.0.5 I suspect php's limitation of int to 32 bits to be the cause, as filesize("backup.tar.gz") gives me an error, too. (PHP Warning: filesize(): stat failed for ...)

The script provided works using the cli version of php5 compilied on the same system at the same time as the apache version. Reproduce code: --------------- <?php print "<pre>"; $file = "/tmp/tester.file"; for ($i = 0; $i < 6; $i++) { @unlink($file); $cmd = "dd if=/dev/zero of=$file bs=1024 count=1024 seek={$i}M"; echo $cmd . "\n"; system($cmd); system("ls -lh $file"); echo "File Exists: " . file_exists($file) . "\n"; print "\n"; } @unlink($file); print "</pre>"; ?> Expected result: ---------------- file_exists should return true even though the file is >= 2 gig Actual result: -------------- file_exists returns false if >= 2 gig ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=32095&edit=1
