Assume that info->children_attached means that this is called from
|
|
direct use of MERGE, not from a MySQL server. In this case the
|
|
children must be closed and info->rec_per_key_part is part of the
|
|
'info' multi_alloc.
|
|
If info->children_attached is false, this is called from a MySQL
|
|
server. Children are closed independently but info->rec_per_key_part
|
|
must be freed.
|
|
Just in case of a server panic (myrg_panic()) info->children_attached
|
|
might be true. We would close the children though they should be
|
|
closed independently and info->rec_per_key_part is not freed.
|
|
This should be acceptable for a panic.
|
|
In case of a MySQL server and no children, children_attached is
|
|
always true. In this case no rec_per_key_part has been allocated.
|
|
So it is correct to use the branch where an empty list of tables is
|
|
(not) closed.
