Igor Babaev	1c7ba7ba2f	Fixed bug #51092 . The function JOIN_CACHE::read_all_record_fields could return 0 for an incremental join cache in two cases: 1. there were no more records in the associated join buffer 2. there was no table fields stored in the join buffer. As a result the function JOIN_CACHE::get_record() could return prematurely and did not read all needed fields from join buffers into the record buffer. Now the function JOIN_CACHE::read_all_record_fields returns -1 if there are no more records in the associated join buffer.	2010-03-06 11:14:55 -08:00

The main patch for MWL#128: Implement Block Nested Loop Hash Join.

Fixed bug #51092 .

The function JOIN_CACHE::read_all_record_fields could return 0
for an incremental join cache in two cases:
1. there were no more records in the associated join buffer
2. there was no table fields stored in the join buffer.
As a result the function JOIN_CACHE::get_record() could
return prematurely and did not read all needed fields from
join buffers into the record buffer.

Now the function JOIN_CACHE::read_all_record_fields returns
-1 if there are no more records in the associated join buffer.
