Add extra sleeps (conditionally) if user-ndb-object still exists during shutdown
Note: This is not in anyway optimal, but i dont't really know in which order should be shutdown
but it fixes problem...
sql/ha_ndbcluster_binlog.cc:
Add extra wait loop to make user "user" ndb-object go away...
otherwise user thread can have ongoing SUB_DATA
storage/ndb/include/ndbapi/ndb_cluster_connection.hpp:
Add interface for getting active ndb-object count
storage/ndb/src/ndbapi/Ndbif.cpp:
Add return in case of incorrect magic
storage/ndb/src/ndbapi/TransporterFacade.cpp:
Add interface for getting active ndb-object count
storage/ndb/src/ndbapi/ndb_cluster_connection.cpp:
Add interface for getting active ndb-object count

|
|
* Any NDB application program should begin with the creation of a

* single Ndb_cluster_connection object, and should make use of one
|
|
* and only one Ndb_cluster_connection. The application connects to
|
|
* a cluster management server when this object's connect() method is called.
|
|
* By using the wait_until_ready() method it is possible to wait
|
|
* for the connection to reach one or more storage nodes.
