Finder performance 2008 Filesystem in Userspace

  • I mounted a MacFUSE volume but I don't see a volume icon on the Desktop
  • I mounted a MacFUSE volume but I don't see a volume icon in the Finder's sidebar
  • sshfs isn't meant to replace things such as NFS, AFP, and SMB
  • ...5 more annotations...
  • a substitute when you don't have any remote file sharing access to a computer, but you do have sftp access

      A rich experience, with which users of Apple Finder and Mac OS X are accustomed, can not be guaranteed within the limitations of a protocol such as FTP.

      Hint: Finder does very much more than simply transfer files. Much of the Finder experience, which users (naturally) take for granted, is thanks to extensive use of extended attributes and metadata.

      Users of FTP, SFTP and SHH services: please, pay attention! The best marriage of Apple Finder and Mac OS X to a remote file system is: Apple Filing Protocol (AFP).
  • MacFUSE allows access to a volume only to the user who mounted the volume. All other users, including the superuser is denied access
  • nontrivial user-space file systems can still be complex, and their performance/behavior can depend upon numerous factors besides MacFUSE itself
  • When in doubt, feel free to post your questions on the macfuse group
  • MacFUSE itself isn't a distributed remote file system

2009 Filesystem in Userspace

shared by Graham Perrin on 17 Jan 09 - Cached
  • MacFUSE provides a flexible and adaptive mechanism to handle extended attributes (including things such as Finder Info, Resource Forks, and ACLs)
  • extended attributes as Apple Double (._) files
  • all or only some extended attributes
  • ...14 more annotations...
  • To properly support ACLs, a user-space file system must correctly handle the com.apple.system.Security extended attribute
  • MacFUSE supports Mac OS X access control lists (ACLs)
  • With auto_xattr, the kernel will /always/ use ._ files
  • MacFUSE limits volume access to the user that mounted the volume
  • blanket denial is a first line of defense
  • allow_other to turn the blanket denial off
  • not a means of distributed file sharing
  • SFTP is merely a utility
  • create a true distributed file system based on MacFUSE
  • nolocalcaches makes the operating system work in an abnormal mode
  • relevant code paths may not have been well tested
  • overhead
  • file operations could end up being /much/ slower
  • SFTP provides no synchronization or locking

  • problem is in attempting to drag-n- drop (or copy-n-paste) files from the HFS+
  • haven't found a combination of default_permissions, defer_permissions, noappledouble and noapplexattr options (or absence of all of them) that works
  • problems that you are experiencing are almost certainly down to something else
  • ...2 more annotations...
  • if you don't implement xattrs MacFuse will work
  • If you can repeat a problem with the loopback then it may be a problem with MacFUSE - if not the problem is yours

    Exemplary of a factor (in this case, NCP - Novell Core Protocol) that could not be guessed from the client perspective, and that may lead to puzzling behaviour when MacFUSE and applications such as Apple Finder are added to the equation.

  • Finder, other applications, and even parts of the OS that would would not expect may be requesting directory contents or file attributes on your file system at any time. They will even do this for files and directories that don't exist

  • behaving as much like a "standard" file system as possible

stack MacFUSE

shared by Graham Perrin on 14 Nov 08 - Cached
  • I think it _can_ be solved   at the MacFUSE level using a transparent "stacking" FUSE filesystem   that will cache appledobule files _locally_
  • It would be a very significant contribution to the Mac and FUSE   communities if such a thing were built, as then all network FUSE   filesystems like S3, FTP and SSH would see functionality and   performance gains
  • Graham Perrin on 14 Nov 08
