features/marker: fix race-conditions, memory corruptions and fd-leaks.

2011-07-20T13:12:42+00:00

  - remove xattrs from newpath after rename is complete.
  - hold inodelk on both parents (if they are different) before doing rename
    and gather contribution values of oldpath and newpath to their parents
    while still holding the locks. Use these contribution values to reduce
    parent sizes.
  - performance optimization: abort updation process if delta is zero.
  - libglusterfs/call-stub: Allow unwinding of frames for rename during
    call_resume_unwind.
  - fixes in dirty inode healing codepath:
  	- fix fd-leak of fd opened on the directory.
  	- don't add (instead just assign) next offset at which readdir has to
          be sent to local->d_off.
        - assign to local->d_off before winding lookup call to get child
          contribution.
  - use mutexes while accessing contribution values stored in inode context.
  - use contribution values from backend instead of in-memory while reducing
    parent sizes during rename
  - wipe parent_loc in marker_local_unref.
  - check for refcount being zero holding lock in quota_local_unref.
  - hold parent inodelk during creation of xattrs on directory.
  - use contribution value to reduce parent's size, if the value to be
    subtracted is not passed as argument to reduce_parent_size.
  - skip contribution creation on root.

features/marker-quota: reduce contributions to parents during unlink only if it is the last link.

2011-04-18T14:42:23+00:00

- since we are not having different contributions for different (parent, name)
    pairs, but only for different parents, links present in the same directory
    will have only one contribution representing all of them. Hence parents will
    not be updated for each link call and parents account for just file-size
    instead of (numlinks * filesize). However this patch will cause issues
    for links present accross directories, as only one of their contributions
    is subtracted when all of them removed (Here all the links are accounted
    in their parents, thereby total size accounted is [numlinks * filesize]).
