Subject [jira] Closed: (IO-91) FileSystemUtils.freeSpace does not work on Sun Solaris
Date Tue, 29 Aug 2006 20:53:23 GMT
     [ http://issues.apache.org/jira/browse/IO-91?page=all ]

Stephen Colebourne closed IO-91.
--------------------------------

    Resolution: Fixed

- FileSystemUtils.freeSpace deprecated, replaced by freeSpaceKb
  - freeSpace returns a result that varies by operating system and
    thus isn't that useful
  - freeSpaceKb returns much better and more consistent results
  - freeSpaceKb existed in v1.2, so this is a gentle cutover

- FileSystemUtils.freeSpace [IO-91]
  - This is now documented not to work on SunOS 5
