634d3991ab Bug #23184: SELECT causes server crash
Item::val_xxx() may be called by the server several times at execute time 
 for a single query. Calls to val_xxx() may be very expensive and sometimes
 (count(distinct), sum(distinct), avg(distinct)) not possible.
 To avoid that problem the results of calculation for these aggregate 
 functions are cached so that val_xxx() methods just return the calculated 
 value for the second and subsequent calls.

f51d0812a7 Bug #21809: Error 1356 while selecting from view with grouping though underlying
select OK.
The SQL parser was using Item::name to transfer user defined function attributes
to the user defined function (udf). It was not distinguishing between user defined 
function call arguments and stored procedure call arguments. Setting Item::name 
was causing Item_ref::print() method to print the argument as quoted identifiers 
and caused views that reference aggregate functions as udf call arguments (and 
rely on Item::print() for the text of the view to store) to throw an undefined 
identifier error.
Overloaded Item_ref::print to print aggregate functions as such when printing
the references to aggregate functions taken out of context by split_sum_func2()
Fixed the parser to properly detect using AS clause in stored procedure arguments
as an error.
Fixed printing the arguments of udf call to print properly the udf attribute.

48cf65c037 BUG#23175 - MYISAM crash/repair failed during repair
Repair table could crash a server if there is not sufficient
memory (myisam_sort_buffer_size) to operate. Affects not only
repair, but also all statements that use create index by sort:
repair by sort, parallel repair, bulk insert.

Return an error if there is not sufficient memory to store at
least one key per BUFFPEK.

Also fixed memory leak if thr_find_all_keys returns an error.


myisam/sort.c:
  maxbuffer is number of BUFFPEK-s for repair. It is calculated
  as records / keys. keys is number of keys that can be stored
  in memory (myisam_sort_buffer_size). There must be sufficient
  memory to store both BUFFPEK-s and keys. It was checked
  correctly before this patch. However there is another
  requirement that wasn't checked: there must be sufficient
  memory for at least one key per BUFFPEK, otherwise repair
  by sort/parallel repair cannot operate.
  
  Return an error if there is not sufficient memory to store at
  least one key per BUFFPEK.
  
  Also fixed memory leak if thr_find_all_keys returns an error.

841ea461ce Bug#21798: memory leak during query execution with subquery in column
list using a function
When executing dependent subqueries they are re-inited and re-exec() for 
each row of the outer context.
The cause for the bug is that during subquery reinitialization/re-execution,
the optimizer reallocates JOIN::join_tab, JOIN::table in make_simple_join()
and the local variable in 'sortorder' in create_sort_index(), which is
allocated by make_unireg_sortorder().
Care must be taken not to allocate anything into the thread's memory pool
while re-initializing query plan structures between subquery re-executions.
All such items mush be cached and reused because the thread's memory pool
is freed at the end of the whole query.
Note that they must be cached and reused even for queries that are not 
otherwise cacheable because otherwise it will grow the thread's memory 
pool every time a cacheable query is re-executed. 
We provide additional members to the JOIN structure to store references 
to the items that need to be cached.

decf9082fb Bug #22342: No results returned for query using max and group by
When using index for group by and range access the server isolates    
 a set of ranges based on the conditions over the key parts of the
 index used. Then it uses only the ranges over the GROUP BY fields to
 jump from one group to another. Since the GROUP BY fields may form a
 prefix over the index, we may use only a prefix of the ranges produced
 by the range optimizer.
 Each range contains a notion on whether it includes its border values.
 The problem is that when using a range prefix, the last range is open
 because it assumes that there is a range on the next keypart. Thus when
 we use a prefix range as it is, it excludes all border values.
 The solution is when ignoring the suffix of the range conditions 
 (to jump over the GROUP BY prefix only) the server must change the 
 remaining intervals so they always contain their borders, e.g. 
 if the whole range was :
 (1,-inf) <= (<group_by_col>,<min_max_arg_col>) < (1, 3) we must make
 (1) <= (<group_by_col>) <= (1) because (a,b) < (c1,c2) means :
 a < c1 OR (a = c1 AND b < c2).

ffc1facce8 Bug #22367: Optimizer uses ref join type instead of eq_ref for simple join on
strings
MySQL is setting the flag HA_END_SPACE_KEYS for all the keys that reference
text or varchar columns with collation different than binary.
This was done to handle correctly the situation where a lookup on such a key
may return more than 1 row because of the presence of many rows that differ
only by the amount of trailing space in the table's string column.
Inserting such values however appears to violate the unique checks on 
INSERT/UPDATE. Thus that flag must not be set as it will prevent the optimizer
from choosing a faster access method.
This fix removes the setting of the HA_END_SPACE_KEYS flag.

750a2a0b86 BUG#14019 : group by converts literal string to column name
When resolving unqualified name references MySQL was not
   checking what is the item type for the reference. Thus
   e.g a string literal item that has by convention a name
   equal to its string value will also work as a reference to 
   a SELECT list item or a table field.
   Fixed by allowing only Item_ref or Item_field to referenced by
   (unqualified) name.

67770b7671 Bug#14959: ALTER TABLE isn't able to rename a view
The mysql_alter_table() was able to rename only a table.

The view/table renaming code is moved from the function rename_tables 
to the new function called do_rename().
The mysql_alter_table() function calls it when it needs to rename a view.

3109da7719 Bug#8283 - OPTIMIZE TABLE causes data loss
OPTIMIZE TABLE with myisam_repair_threads > 1 performs a non-quick 
parallel repair. This means that it does not only rebuild all 
indexes, but also the data file.

Non-quick parallel repair works so that there is one thread per 
index. The first of the threads rebuilds also the new data file.

The problem was that all threads shared the read io cache on the
old data file. If there were holes (deleted records) in the table,
the first thread skipped them, writing only contiguous, non-deleted
records to the new data file. Then it built the new index so that
its entries pointed to the correct record positions. But the other
threads didn't know the new record positions, but put the positions
from the old data file into the index.

The new design is so that there is a shared io cache which is filled
by the first thread (the data file writer) with the new contiguous
records and read by the other threads. Now they know the new record
positions.

Another problem was that for the parallel repair of compressed
tables a common bit_buff and rec_buff was used. I changed it so
that thread specific buffers are used for parallel repair.

A similar problem existed for checksum calculation. I made this
multi-thread safe too.

  the writer copies the data from his write buffer to the shared

45cad70ff4 Bug #22781: SQL_BIG_RESULT fails to influence sort plan
Currently SQL_BIG_RESULT is checked only at compile time.
 However, additional optimizations may take place after
 this check that change the sort method from 'filesort'
 to sorting via index. As a result the actual plan
 executed is not the one specified by the SQL_BIG_RESULT
 hint. Similarly, there is no such test when executing
 EXPLAIN, resulting in incorrect output.
 The patch corrects the problem by testing for
 SQL_BIG_RESULT both during the explain and execution
 phases.

2268afedea BUG#21381 - Engine not notified about multi-table UPDATE IGNORE
Though this is not storage engine specific problem, I was able to
repeat this problem with BDB and NDB engines only. That was the
reason to add a test case into ndb_update.test. As a result
different bad things could happen.

BDB has removed duplicate rows which is not expected.
NDB returns an error.

For multi table update notify storage engine about UPDATE IGNORE
as it is done in single table UPDATE.
