ceph/PendingReleaseNotes

v0.78
~~~~~

* CephFS recently added support for a new 'backtrace' attribute on
  file data objects that is used for lookup by inode number (i.e., NFS
  reexport and hard links), and will later be used by fsck repair.
  This replaces the existing anchor table mechanism that is used for
  hard link resolution.  In order to completely phase that out, any
  inode that has an outdated backtrace attribute will get updated when
  the inode itself is modified.  This will result in some extra workload
  after a legacy CephFS file system is upgraded.

* The per-op return code in librados' ObjectWriteOperation interface
  is now filled in.

* The librados cmpxattr operation now handles xattrs containing null bytes as
  data rather than null-terminated strings.

rbd: return 0 and an empty list when pool is entirely empty rbd_list will return -ENOENT when no rbd_directory object exists. Handle this in the cli tool and interpret it as success with an empty list. Add this to the release notes since it changes command line behavior.

Objecter: keep ObjectOperation rval pointers for writes Just before sending an op, prepare_mutate_op() is called, creating a new Op. prepare_read_op() already copied over all the out-params correctly, but for write operations the individual op return value pointers were not copied, so they would not be filled in. With this fixed, librados users can get the per-op return codes again. Partially fixes: #6483 Signed-off-by: Josh Durgin <josh.durgin@inktank.com> 2014-01-30 14:55:29 +00:00

ReplicatedPG: avoid undefined behavior in xattr comparison Reading past the end of a pointer returned by string.data() in c++98 is undefined. While we're fixing this, also allow comparison of xattrs containing null bytes. Fixes: #7250 Backport: dumpling Signed-off-by: Josh Durgin <josh.durgin@inktank.com> 2014-02-07 02:50:50 +00:00
