In the case of loose scan used as input for order by, end_send()
didn't detect correctly that a loose scan was used, and didn't copy
the non-aggregated fields from the temp table used for ORDER BY.
The fix uses the fact that the quick select used for sorting is
attached to JOIN::pre_sort_join_tab instead of JOIN::join_tab.
Backport the fix olav.sandstaa@sun.com-20101102184747-qfuntqwj021imy9r:
"Fix for Bug#52660 Perf. regr. using ICP for MyISAM on range queries on an index containing TEXT"
(together with further fixes in that code) into MyISAM and Aria.
Apply the patch from Patryk Pomykalski:
- create_internal_tmp_table_from_heap() will now return information whether
the last row that we tried to write was a duplicate row.
(mysql-5.6 also has this change)
- merge_same_index_scans() may put the same SEL_ARG tree in multiple result plans.
make it call incr_refs() on the SEL_ARG trees that it does key_or() on, because
key_or(sel_arg_tree_1, sel_arg_tree_2) call may invalidate SEL_ARG trees pointed
by sel_arg_tree_1 and sel_arg_tree_2.
When a new master is provisioned that does not have any old binlogs,
the @@gtid_slave_pos is used to know where in the GTID history the
provisioning happened. A slave is allowed to connect at the point of
this value of @@gtid_slave_pos, even if that GTID is not in the
binlogs on the new master.
The code to handle this case when the binlog on the newly provisioned
master is completely empty was just wrong (couple of typos). Clearly it
had never been tested ... :-/
When a new master is provisioned that does not have any old binlogs,
the @@gtid_slave_pos is used to know where in the GTID history the
provisioning happened. A slave is allowed to connect at the point of
this value of @@gtid_slave_pos, even if that GTID is not in the
binlogs on the new master.
But --gtid-strict-mode did not correctly handle this case. When strict
mode was enabled, an attempt to connect at the position would cause an
error about holes in the binlog, which is not correct.
This patch adds a hash of GTIDs that need to be treated specially by
GTID strict mode to deal correctly with this case.
If there is a key cache resize,a thread writing to key cache, will pause waiting until resize finishes. However this thread is won't be woken, because resize does not signaling waiters anymore. This is a regression introduced in WL#86(segmented MyISAM key cache)
The fix is to unconditionally release threads waiting on resize_queue when resize finishes, as in pre-WL#86 code.
