eb057dce20 MDEV-15035 Wrong results when calling a stored procedure 
multiple times with different arguments.

If the ON expression of an outer join is an OR formula with one
of the disjunct being a constant formula then the expression
cannot be null-rejected if the constant formula is true. Otherwise
it can be null-rejected and if so the outer join can be converted
into inner join. This optimization was added in the patch for
mdev-4817. Yet the code had a defect: if the query was used in
a stored procedure with parameters and the constant item contained
some of them then the value of this constant item depended on the
values of the parameters. With some parameters it may be true,
for others not. The validity of conversion to inner join is checked
only once and it happens only for the first call of procedure.
So if the  parameters in the first call allowed the conversion it
was done and next calls used the transformed query though there
could be calls whose parameters made the conversion invalid.

Fixed by cheking whether the constant disjunct in the ON expression
originally contained an SP parameter. If so the expression is not
considered as null-rejected. For this check a new item's attribute
was intruduced: Item::with_param. It is calculated for each item
by fix fields() functions.
Also moved the call of optimize_constant_subqueries() in
JOIN::optimize after the call of simplify_joins(). The reason
for this is that after the optimization introduced by the patch
for mdev-4817 simplify_joins() can use the results of execution
of non-expensive constant subqueries and this is not valid.

c2c93fc6e4 MDEV-14164: Unknown column error when adding aggregate to function in oracle style procedure FOR loop 
Make differentiation between pullout for merge and pulout of outer field during exists2in transformation.
In last case the field was outer and so we can safely start from name resolution context of the SELECT where it was pulled.
Old behavior lead to inconsistence between list of tables and outer name resolution context (which skips one SELECT for merge purposes) which creates problem vor name resolution.

2fcd8c1252 MDEV-13173 An RLIKE that previously worked on 10.0 now returns "Got error 'pcre_exec: recursion limit of 100 exceeded' from regexp" 
1. use Regexp_processor_pcre::set_recursion_limit() to set the
   recursion limit depending on the current available stack size
2. make pcre stack frame to be estimated no less than 500 bytes.
   sometimes pcre estimates it too low, even though the manual
   says 500+16 bytes (it was estimated only 188 for me, actual
   frame size was 512).
3. do it for embedded too

798fcb5416 bugfix: cmp_item_row::alloc_comparators() allocated on the wrong arena 
it used current_thd->alloc() and allocated on the thd's execution arena,
not on table->expr_arena.

Remove THD::arena_for_cached_items that is temporarily set in
update_virtual_fields(), and replaces THD arena in get_datetime_value().
Instead set THD arena to table->expr_arena for the whole  duration
of update_virtual_fields()

67e2028161 MDEV-9690 concurrent queries with virtual columns crash in temporal code 
Item_func_le included Arg_comparator. Arg_comparator remembered
the current_thd during fix_fields and used that value during
execution to allocate Item_cache in get_datetime_value().
But for vcols fix_fields and val_int can happen in different threads.

Same bug for Item_func_in using in_datetime or cmp_item_datetime,
both also remembered current_thd at fix_fields() to use it later
for get_datetime_value().

As a fix, these objects no longer remember the current_thd,
and get_datetime_value() uses current_thd at run time. This
should not increase the number of current_thd calls much, as
Item_cache is created only once anyway.

9a987142f9 MDEV-9745 Crash with CASE WHEN TRUE THEN COALESCE(CAST(NULL AS UNSIGNED)) ELSE 4 END 
This is a backport of the patch for MDEV-9653 (fixed earlier in 10.1.13).

The code in Item_func_case::fix_length_and_dec() did not
calculate max_length and decimals properly.

In case of any numeric result (DECIMAL, REAL, INT) a generic method
Item_func_case::agg_num_lengths() was called, which could erroneously result
into a DECIMAL item with max_length==0 and decimals==0, so the constructor of
Field_new_decimals tried to create a field of DECIMAL(0,0) type,
which caused a crash.

Unlike Item_func_case, the code responsible for merging attributes in
Item_func_coalesce::fix_length_and_dec() works fine: it has specific execution
branches for all distinct numeric types and correctly creates a DECIMAL(1,0)
column instead of DECIMAL(0,0) for the same set of arguments.

The fix does the following:
- Moves the attribute merging code from Item_func_coalesce::fix_length_and_dec()
  to a new method Item_func_hybrid_result_type::fix_attributes()
- Removes the wrong code from Item_func_case::fix_length_and_dec()
  and reuses fix_attributes() in both Item_func_coalesce::fix_length_and_dec()
  and Item_func_case::fix_length_and_dec()
- Fixes count_real_length() and count_decimal_length() to get an array
  of Items as an argument, instead of using Item::args directly.
  This is needed for Item_func_case::fix_length_and_dec().
- Moves methods Item_func::count_xxx_length() from "public" to "protected".
- Removes Item_func_case::agg_num_length(), as it's not used any more.
- Additionally removes Item_func_case::agg_str_length(),
  as it also was not used (dead code).

Item_func_ifnull::date_op() and Item_func_coalesce::date_op() could
erroneously return 0000-00-00 instead of NULL when get_date()
was called with the TIME_FUZZY_DATES flag, e.g. from LEAST().

a7fb5aecfd Bug#19941403: FATAL_SIGNAL(SIG 6) IN BUILD_EQUAL_ITEMS_FOR_COND | IN SQL/SQL_OPTIMIZER.CC:1657 
Problem:
At the end of first execution select_lex->prep_where is pointing to
a runtime created object (temporary table field). As a result
server exits trying to access a invalid pointer during second
execution.

Analysis:
While optimizing the join conditions for the query, after the
permanent transformation, optimizer makes a copy of the new
where conditions in select_lex->prep_where. "prep_where" is what
is used as the "where condition" for the query at the start of execution.
W.r.t the query in question, "where" condition is actually pointing
to a field in the temporary table. As a result, for the  second
execution the pointer is no more valid resulting in server exit.

Fix:
At the end of the first execution, select_lex->where will have the
original item of the where condition.
Make prep_where the new place where the original item of select->where
has to be rolled back.
Fixed in 5.7 with the wl#7082 - Move permanent transformations from
JOIN::optimize to JOIN::prepare

Patch for 5.5 includes the following backports from 5.6:

Bugfix for Bug12603141 - This makes the first execute statement in the testcase
pass in 5.5

However it was noted later in in Bug16163596 that the above bugfix needed to
be modified. Although Bug16163596 is reproducible only with changes done for
Bug12582849, we have decided include the fix.

Considering that Bug12582849 is related to Bug12603141, the fix is
also included here. However this results in Bug16317817, Bug16317685,
Bug16739050. So fix for the above three bugs is also part of this patch.

2e3e818048 MDEV-7445: Server crash with Signal 6 
Problem was in rewriting left expression which had 2 references on it. Solved with making subselect reference main.

Item_in_optimized can have not Item_in_subselect reference in left part so type casting with no check is dangerous.

Item::cols() should be checked after Item::fix_fields().

4acc7615ee Bug #19929406: HANDLE_FATAL_SIGNAL (SIG=11) IN 
__MEMMOVE_SSSE3_BACK FROM STRING::COPY

Issue:
-----
While using row comparators, the store_value functions call
val_xxx functions in the prepare phase. This can cause
valgrind issues.

SOLUTION:
---------
Setting up of the comparators should be done by
alloc_comparators in the prepare phase. Also, make sure
store_value will be called only during execute phase.

This is a backport of the fix for Bug#17755540.

70823e1d91 MDEV-5120 Test suite test maria-no-logging fails 
The reason for the failure was a bug in an include file on debian that causes 'struct stat'
to have different sized depending on the environment.

This patch fixes so that we always include my_global.h or my_config.h before we include any other files.

Other things:
- Removed #include <my_global.h> in some include files; Better to always do this at the top level to have as few
  "always-include-this-file-first' files as possible.
- Removed usage of some include files that where already included by my_global.h or by other files.
