BUG #14524
Patch that fixes crashing when partition uses blackole for
underlying tables.
mysql-test/r/partition.result:
BUG #14524 New test result
mysql-test/t/partition.test:
BUG #14524
New test
sql/ha_partition.cc:
BUG# 14524
Added new class var m_no_locks to keep track of the absense of locks. If
'0', then lock_count returns 0, which keeps thr_multi_lock from crashing
in the case of the underlying table being ha_blackhole.
sql/ha_partition.h:
BUG #14524
Added new class var m_no_locks to keep track of lock count
sql/lock.cc:
BUG #14524
DBUG PRINTs and ENTERs to make tracking the bug easier. I think these are
useful regardless of this bug.
sql/sql_partition.cc:
BUG #14524
Changed umlaut o to allow fixing bug 14524 using DDD (file would not display
in DDD)
