revno: 2617.23.20
committer: Konstantin Osipov <kostja@sun.com>
branch nick: mysql-6.0-runtime

message:
  WL#4284 "Transactional DDL locking"
  Review comments: "Objectify" the MDL API.
  MDL_request and MDL_context still need manual construction and
  destruction, since they are used in environment that is averse
  to constructors/destructors.


sql/mdl.cc:
  Improve comments.
  Add asserts to backup()/restore_from_backup()/merge() methods.
  Fix an order bug in the error path of mdl_acquire_exclusive_locks():
  we used to first free a ticket object, and only then exclude
  it from the list of tickets.
