[Gluster-devel] ctime weirdness

[Emmanuel Dreyfus]

Hello

Here is a NetBSD behavior that looks pathological:
(it happens on a FUSE mount but not a native mount):

# touch a
# stat -x a 
  File: "a"
  Size: 0            FileType: Regular File
  Mode: (0644/-rw-r--r--)         Uid: (    0/    root)  Gid: (    0/
wheel)
Device: 203,7   Inode: 13726586830943880794    Links: 1

# cat a > /dev/null  
# stat -x a          
  File: "a"
  Size: 0            FileType: Regular File
  Mode: (0644/-rw-r--r--)         Uid: (    0/    root)  Gid: (    0/
wheel)

NetBSD FUSE implementation does not sends ctime with SETATTR. Looking at
glusterfs FUSE xlator, I see setattr code does not handle ctime either.

How does that happen? What wrong does NetBSD SETATTR does?
