#39520 [NEW]: disk_free_space assumes a blocksize of 4096

From: david at triax dot jp Operating system: RedHat Enterprise ES 4 PHP version: 5.2.0 PHP Bug Type: Filesystem function related Bug description: disk_free_space assumes a blocksize of 4096 Description: ------------ Using disk_free_space() on an NFS mount produced incorrect results so checking with strace, it seems PHP is ignoring the value of f_bsize and either using f_frsize or just using a fixed blocksize of 4096. I haven't checked the source code yet. Calling stat() on the same path shows the correct blocksize for the filesystem, in my case 32768, and so dividing the output of disk_free_space() by 4096 and multiplying by the result of stat()'s blksize element. Expected result: ---------------- I expected the value of disk_free_space() to use the same block size as reproted by stat() on the same path. Actual result: -------------- disk_free_space() seems to use a fixed 4096 byte block size. -- Edit bug report at http://bugs.php.net/?id=39520&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=39520&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=39520&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=39520&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=39520&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=39520&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=39520&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=39520&r=needscript Try newer version: http://bugs.php.net/fix.php?id=39520&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=39520&r=support Expected behavior: http://bugs.php.net/fix.php?id=39520&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=39520&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=39520&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=39520&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=39520&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=39520&r=dst IIS Stability: http://bugs.php.net/fix.php?id=39520&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=39520&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=39520&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=39520&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=39520&r=mysqlcfg
