#39520 [Opn->Bgs]: disk_free_space uses f_frsize but it should use f_bsize

ID: 39520 Updated by: iliaa@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: I've checked the current behavior against other applications and utilities that calculate free disk space and PHP's approach is perfectly inline with what other people are doing. Previous Comments: ------------------------------------------------------------------------ [2006-11-16 03:46:01] david at triax dot jp Changed the subject to reflect the actual bug. From the stat(2) man page, fr_size is "the 'preferred' block-size for efficient file system I/O." This means that it's *not* the blocksize of the actual device and is not useful for calculating the size of the device. ------------------------------------------------------------------------ [2006-11-16 03:42:04] david at triax dot jp This is not a bogus bug.

Please reread. ------------------------------------------------------------------------ [2006-11-15 11:35:32] david at triax dot jp As I wrote initially, it is either using f_frsize or just using a fixed blocksize and as you point out it's using f_frsize, and that is wrong. It should use f_bsize when calculating free space. ------------------------------------------------------------------------ [2006-11-15 09:53:40] tony2001@php.net No, you are wrong.
