#39520 [Opn->Bgs]: disk_free_space assumes a blocksize of 4096

ID: 39520 Updated by: tony2001@php.net Reported By: david at triax dot jp -Status: Open +Status: Bogus Bug Type: Filesystem function related Operating System: RedHat Enterprise ES 4 PHP Version: 5.2.0 New Comment: No, you are wrong. See lines 365-369 here: http://cvs.php.net/viewvc.cgi/php-src/ext/standard/filestat.c?view=annotate Previous Comments: ------------------------------------------------------------------------ [2006-11-15 05:26:09] david at triax dot jp 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 this bug report at http://bugs.php.net/?id=39520&edit=1
