MDEV-6878: Use of uninitialized saved_primary_key in Mrr_ordered_index_reader::resume_read()

2014-10-28T22:37:58+00:00

(Backport to 5.3)
(variant #2, with fixed coding style)
- Make Mrr_ordered_index_reader::resume_read() restore index position 
  only if it was saved before with Mrr_ordered_index_reader::interrupt_read().

MDEV-5037: Server crash on a JOIN on a derived table with join_cache_level > 2

2013-09-20T10:47:38+00:00

- The crash was caused because the optimizer called handler->multi_range_read_info()
  on a derived temporary table.  That table has been created, but not opened yet.
  Because of that, handler::table was NULL, which caused crash.
  Fixed by changing DS-MRR methods to use handler::table_share instead. 
  handler::table_share is set in handler ctor, so this should be safe.

Make EXPLAIN better at displaying MRR/BKA:

2011-04-02T10:04:45+00:00

- "Using MRR" is no longer shown with range access.
- Instead, both range and BKA accesses will show one of the following:
  = "Rowid-ordered scan"
  = "Key-ordered scan"
  = "Key-ordered Rowid-ordered scan"
depending on whether DS-MRR implementation will do scan keys in order, rowids in order,
or both.
- The patch also introduces a way for other storage engines/MRR implementations to
  pass information to EXPLAIN output about the properties of employed MRR scans.
