cab267ecc7 Bug#37548: result value erronously reported being NULL in certain subqueries
When switching to indexed ORDER BY we must be sure to reset the index read
flag if we are switching from a covering index to non-covering.

b6e3a9e28c Fixed bug #38191.
Calling List<Cached_item>::delete_elements for the same list twice
caused a crash of the server in the function JOIN::cleaunup.
Ensured that delete_elements() in JOIN::cleanup would be called only once.

1fc4954d30 Post-merge fixes.
The file tree in mtr's vardir has changed so an old
hard-coded path in mysql-test/t/subselect.test didn't
work.
Fix: update the paths in the test.

0e1709bde6 Bug#37627: Killing query with sum(exists()) or avg(exists()) reproducibly crashes server
When there is an error executing EXISTS predicates they return NULL as their string
or decimal value but don't set the NULL value flag.
Fixed by returning 0 (as a decimal or a string) on error exectuting the subquery.
Note that we can't return NULL as EXISTS is not supposed to return NULL.

0fb1527e95 Bug #36011: server crash with explain extended on query
with dependent subqueries
An IN subquery is executed on EXPLAIN when it's not correlated.
If the subquery required a temporary table for its execution
not all the internal structures were restored from pointing to
the items of the temporary table to point back to the items of
the subquery.
Fixed by restoring the ref array when a temp tables were used in
executing the IN subquery during EXPLAIN EXTENDED.

The new test case check that a query with at least 4 level subquery nesting

c1d0dd94bb Fix for Bug#32538: View definition picks up character set,
but not collation.

The problem here was that text literals in a view were always
dumped with character set introducer. That lead to loosing
collation information.

The fix is to dump character set introducer only if it was
in the original query. That is now possible because there 
is no problem any more of loss of character set of string
literals in views -- after WL#4052 the view is dumped 
in the original character set.

c71a6428d8 BUG#33794 "MySQL crashes executing specific query":
The problem occurred when one had a subquery that had an equality X=Y where 
Y referred to a named select list expression from the parent select. MySQL 
crashed when trying to use the X=Y equality for ref-based access. 

Fixed by allowing non-Item_field items in the described case.

8845553a81 Bug#33675: Usage of an uninitialized memory by filesort in a subquery caused
server crash.

The filesort implementation has an optimization for subquery execution which
consists of reusing previously allocated buffers. In particular the call to
the read_buffpek_from_file function might be skipped when a big enough buffer
for buffer descriptors (buffpeks) is already allocated. Beside allocating
memory for buffpeks this function fills allocated buffer with data read from
disk. Skipping it might led to using an arbitrary memory as fields' data and
finally to a crash.

Now the read_buffpek_from_file function is always called. It allocates
new buffer only when necessary, but always fill it with correct data.

89a208850a Bug#31177: Server variables can't be set to their current values
Default values of variables were not subject to upper/lower bounds
and step, while setting variables was. Bounds and step are also
applied to defaults now; defaults are corrected quietly, values
given by the user are corrected, and a correction-warning is thrown
as needed. Lastly, very large values could wrap around, starting
from 0 again. They are bounded at the maximum value for the
respective data-type now if no lower maximum is specified in the
variable's definition.


client/mysql.cc:
  correct maxima in options array
client/mysqltest.c:
  adjust minimum for "sleep" option so default value is no longer
  out of bounds.
include/m_string.h:
  ullstr() - the unsigned brother of llstr()
include/my_getopt.h:
  Flag if we bounded the value (that is, correct anything aside from
  making value a multiple of block-size)

mysql-test/r/variables.result:
  correct results: bounds and step apply to variables' default values, too
mysql-test/t/variables.test:
  correct results: bounds and step apply to variables' default values, too
mysys/my_getopt.c:
  - apply bounds/step to default values of variables (based on work by serg)
  - print complaints about incorrect values for variables (truncation etc.,
    by requestion of consulting)
  - if no lower maximum is specified in variable definition, bound unsigned
    values at their maximum to prevent wrap-around
  - some calls to error_reporter had a \n, some didn't. remove \n from calls,
    let reporter-function handle it, so the default reporter behaves like that
    in mysqld
sql/mysql_priv.h:
  correct RANGE_ALLOC_BLOCK_SIZE (cleared with monty)
sql/mysqld.cc:
  correct maxima to correct data-type.
  correct minima where higher than default.
  correct range-alloc-block-size.
  correct inno variables so GET_* corresponds to actual variable's type.
sql/set_var.cc:
  When the new value for a variable is out of bounds, we'll send the
  client a warning (but not if the value was simply not a multiple of
  'blocksize').  sys_var_thd_ulong had this, sys_var_long_ptr_global
  didn't; broken out and streamlined to avoid duplication of code.
strings/llstr.c:

f3f9855d13 Bug #32036: EXISTS within a WHERE clause with a UNION
crashes MySQL 5.122
There was a difference in how UNIONs are handled
on top level and when in sub-query.
Because the rules for sub-queries were syntactically
allowing cases that are not currently supported by
the server we had crashes (this bug) or wrong results
(bug 32051).
Fixed by making the syntax rules for UNIONs match the 
ones at top level.

These rules however do not support nesting UNIONs, e.g.
(SELECT a FROM t1 UNION ALL SELECT b FROM t2) 
 UNION
(SELECT c FROM t3 UNION ALL SELECT d FROM t4)
Supports for statements with nested UNIONs will be
added in a future version.

e9832ceeac Bug #30788: Inconsistent retrieval of char/varchar
Index lookup does not always guarantee that we can
simply remove the relevant conditions from the WHERE
clause. Reasons can be e.g. conversion errors, 
partial indexes etc. 
The optimizer was removing these parts of the WHERE 
condition without any further checking.
This leads to "false positives" when using indexes.
Fixed by checking the index reference conditions
(using WHERE) when using indexes with sub-queries.

870d46819e Bug #32400: Complex SELECT query returns correct result
only on some occasions

Referencing an element from the SELECT list in a WHERE 
clause is not permitted. The namespace of the WHERE
clause is the table columns only. This was not enforced
correctly when resolving outer references in sub-queries.

Fixed by not allowing references to aliases in a 
sub-query in WHERE.

13105534fa Bug#31048: Many nested subqueries may cause server crash.
This bug is actually two. The first one manifests itself on an EXPLAIN
SELECT query with nested subqueries that employs the filesort algorithm.
The whole SELECT under explain is marked as UNCACHEABLE_EXPLAIN to preserve
some temporary structures for explain. As a side-effect of this values of
nested subqueries weren't cached and subqueries were re-evaluated many
times. Each time buffer for filesort was allocated but wasn't freed because
freeing occurs at the end of topmost SELECT. Thus all available memory was
eaten up step by step and OOM event occur.
The second bug manifests itself on SELECT queries with conditions where
a subquery result is compared with a key field and the subquery itself also
has such condition. When a long chain of such nested subqueries is present
the stack overrun occur. This happens because at some point the range optimizer
temporary puts the PARAM structure on the stack. Its size if about 8K and
the stack is exhausted very fast.

Now the subselect_single_select_engine::exec function allows subquery result
caching when the UNCACHEABLE_EXPLAIN flag is set.
Now the SQL_SELECT::test_quick_select function calls the check_stack_overrun
function for stack checking purposes to prevent server crash.
