+# Originally created by John Embretsen, 2011-01-26.
+#
+# Checks for the existence of Perl modules DBI and DBD::mysql as seen from the
+# perl installation used by "external" executable perl scripts, i.e. scripts
+# that are executed as standalone scripts interpreted by the perl installation
+# specified by the "shebang" line in the top of these scripts.
+#
+# If either module is not found, the test will be skipped.
+#
+# For use in tests that call perl scripts that require these modules.
+#
+# This file is intended to work on Unix. Windows may need different treatment.
+# Reasoning:
+#   - "shebangs" are not relevant on Windows, but need to be handled here.
+#   - Perl scripts cannot be made executable on Windows, interpreter must be 
+#     specified.
+#
+# Note that if there are multiple perl installations and not all have the
+# required modules, this check may fail even if the perl in path does have
+# the modules available. This may happen if the perl specified by the script's 
+# shebang (e.g. #!/usr/bin/perl) does not have these modules, and script is 
+# called without specifying the perl interpreter. However, this will be 
+# a correct result in cases where a test calls a script with a similar shebang.

+# We jump through some hoops since there is no direct way to check if an 
+# external command went OK or not from a mysql-test file:
+#
+#   - In theory, we could do as simple as "exec perl -MDBI -MDBD::mysql -e 1",
+#     however we cannot check the result (exit code) from within a test script. 
+#     Also, this may not yield the same result as other uses of perl due to the 
+#     shebang issue mentioned above.
+#   - Instead we use a separate helper perl script that checks for the modules.
+#   - If the modules are found, the perl script leaves a file which sets a
+#     variable that can be read by this file.
+#     If the modules are not found, the perl script does not set this variable,
+#     but leaves an empty file instead.

+# This is done because there is apparently no direct way to transfer

+#
+# This perl script checks for availability of the Perl modules DBI and
+# DBD::mysql using the "current" perl interpreter.
+#
+# Useful for test environment checking before testing executable perl scripts
+# in the MySQL Server distribution.
+#
+# NOTE: The "shebang" on the first line of this script should always point to
+#       /usr/bin/perl, so that we can use this script to check whether or not we
+#       support running perl scripts with such a shebang without specifying the
+#       perl interpreter on the command line. Such a script is mysqlhotcopy.
+#
+#       When run as "checkDBI_DBD-mysql.pl" the shebang line will be evaluated
+#       and used. When run as "perl checkDBI_DBD-mysql.pl" the shebang line is
+#       not used.
+#
+# NOTE: This script will create a temporary file in MTR's tmp dir.
+#       If modules are found, a mysql-test statement which sets a special
+#       variable is written to this file. If one of the modules is not found
+#       (or cannot be loaded), the file will remain empty.
+#       A test (or include file) which sources that file can then easily do
+#       an if-check on the special variable to determine success or failure.
+#
+#       Example:
+#
+#         --let $perlChecker= $MYSQLTEST_VARDIR/std_data/checkDBI_DBD-mysql.pl
+#         --let $resultFile= $MYSQL_TMP_DIR/dbidbd-mysql.txt
+#         --chmod 0755 $perlChecker
+#         --exec $perlChecker
+#         --source $resultFile
+#         if (!$dbidbd) {
+#             --skip Test needs Perl modules DBI and DBD::mysql
+#         } 
+#
+#       The calling script is also responsible for cleaning up after use:
+#
+#         --remove_file $resultFile
+#
+# Windows notes: 
+#   - shebangs may work differently - call this script with "perl " in front.
+#
+# See mysql-test/include/have_dbi_dbd-mysql.inc for example use of this script.
+# This script should be executable for the user running MTR.

+Binlog checksum testing
+=======================
+
+1. How it works.
+The script copies a <suite> to directory <suite>_checksum, 
+collects test case names for t/ directory (except tests from
+disabled def), randomly choose 90% of tests and add them 
+to disabled.def.
+It means that mtr will run only 10% of random tests from each 
+suite.
+At end the script run mtr:
+./mysql-test-run.pl --suite=aaa_checksum,bbb_checksum \
+    --mysqld=--binlog-checksum=CRC32 arg1 ... argN
+
+aaa,bbb 	- suite names from --suite option
+arg1,argN	- other command-line arguments of checksum.pl
+
+2. The options:
+
+--suite=suite1,suite2.  Mandatory option. The list of suites for 
+    binlog checksum testing.
+
+--percent=N, where N is 1..99. Percent of running tests.

-  SYNOPSIS
-    Arg_comparator::can_compare_as_dates()
-    a, b          [in]  items to be compared
-    const_value   [out] converted value of the string constant, if any
-
-  DESCRIPTION
-    Check several cases when the DATE/DATETIME comparator should be used.
-    The following cases are checked:
-      1. Both a and b is a DATE/DATETIME field/function returning string or
-         int result.
-      2. Only a or b is a DATE/DATETIME field/function returning string or
-         int result and the other item (b or a) is an item with string result.
-         If the second item is a constant one then it's checked to be
-         convertible to the DATE/DATETIME type. If the constant can't be
-         converted to a DATE/DATETIME then the compare_datetime() comparator
-         isn't used and the warning about wrong DATE/DATETIME value is issued.
-      In all other cases (date-[int|real|decimal]/[int|real|decimal]-date)
-      the comparison is handled by other comparators.
-    If the datetime comparator can be used and one the operands of the
-    comparison is a string constant that was successfully converted to a
-    DATE/DATETIME type then the result of the conversion is returned in the
-    const_value if it is provided.  If there is no constant or
-    compare_datetime() isn't applicable then the *const_value remains
-    unchanged.

+  @param[in]      type       type context to compare in
 
-  RETURN
-    the found type of date comparison
+  Both *a1 and *a2 can be replaced by this method - typically by constant
+  items, holding the cached converted value of the original (constant) item.

-  DESCRIPTION
+  @details
     Retrieves the correct DATETIME value from given item for comparison by the
     compare_datetime() function.
-    If item's result can be compared as longlong then its int value is used
-    and its string value is used otherwise. Strings are always parsed and
-    converted to int values by the get_date_from_str() function.
-    This allows us to compare correctly string dates with missed insignificant
-    zeros. If an item is a constant one then its value is cached and it isn't
-    get parsed again. An Item_cache_int object is used for caching values. It
-    seamlessly substitutes the original item.  The cache item is marked as
-    non-constant to prevent re-caching it again.  In order to compare
-    correctly DATE and DATETIME items the result of the former are treated as
-    a DATETIME with zero time (00:00:00).
 
-  RETURN
-    obtained value
+    If the value should be compared as time (TIME_RESULT), it's retrieved as
+    MYSQL_TIME. Otherwise it's read as a number/string and converted to time.
+    Constant items are cached, so the convertion is only done once for them.
+
+    Note the f_type behavior: if the item can be compared as time, then
+    f_type is this item's field_type(). Otherwise it's field_type() of
+    warn_item (which is the other operand of the comparison operator).
+    This logic provides correct string/number to date/time conversion
+    depending on the other operand (when comparing a string with a date, it's
+    parsed as a date, when comparing a string with a time it's parsed as a time)
+
+    If the item is a constant it is replaced by the Item_cache_int, that
+    holds the packed datetime value.
+
+  @return
+    MYSQL_TIME value, packed in a longlong, suitable for comparison.

       The field is not in SJ-Materialization nest. We must return the first

-      If we're looking for best substitute for 'ot2.col', we should pick ot1.col

-      execution of SJ-Mat(...) has already finished and we can't rely on the

+
+      First let's note that either it1.col or it2.col participates in 
+      subquery's IN-equality. It can't be otherwise, because materialization is
+      only applicable to uncorrelated subqueries, so the only way we could
+      infer "it1.col=ot1.col" is from the IN-equality. Ok, so IN-eqality has 
+      it1.col or it2.col on its inner side. it1.col is first such item in the
+      join order, so it's not possible for SJ-Mat to be
+      SJ-Materialization-lookup, it is SJ-Materialization-Scan. The scan part
+      of this strategy will unpack value of it1.col=it2.col into it1.col
+      (that's the first equal item inside the subquery), and we'll be able to

-  Rewrite a single-column IN/ALL/ANY subselect
-
-  SYNOPSIS
-    Item_in_subselect::single_value_transformer()
-      join  Join object of the subquery (i.e. 'child' join).
-      func  Subquery comparison creator
-
-  DESCRIPTION
-    Rewrite a single-column subquery using rule-based approach. The subquery
-    
-       oe $cmp$ (SELECT ie FROM ... WHERE subq_where ... HAVING subq_having)
-    
-    First, try to convert the subquery to scalar-result subquery in one of
-    the forms:
-    
-       - oe $cmp$ (SELECT MAX(...) )  // handled by Item_singlerow_subselect
-       - oe $cmp$ <max>(SELECT ...)   // handled by Item_maxmin_subselect
-   
-    If that fails, the subquery will be handled with class Item_in_optimizer, 
-    Inject the predicates into subquery, i.e. convert it to:
+/**
+  Prepare a single-column IN/ALL/ANY subselect for rewriting.
 
-    - If the subquery has aggregates, GROUP BY, or HAVING, convert to
+  @param join  Join object of the subquery (i.e. 'child' join).
 
-       SELECT ie FROM ...  HAVING subq_having AND 
-                                   trigcond(oe $cmp$ ref_or_null_helper<ie>)
-                                   
-      the addition is wrapped into trigger only when we want to distinguish
-      between NULL and FALSE results.
-
-    - Otherwise (no aggregates/GROUP BY/HAVING) convert it to one of the
-      following:
+  @details
 
-      = If we don't need to distinguish between NULL and FALSE subquery:
-        
-        SELECT 1 FROM ... WHERE (oe $cmp$ ie) AND subq_where
+  Prepare a single-column subquery to be rewritten. Given the subquery.
 
-      = If we need to distinguish between those:
+  If the subquery has no tables it will be turned to an expression between
+  left part and SELECT list.
 
-        SELECT 1 FROM ...
-          WHERE  subq_where AND trigcond((oe $cmp$ ie) OR (ie IS NULL))
-          HAVING trigcond(<is_not_null_test>(ie))
+  In other cases the subquery will be wrapped with  Item_in_optimizer which
+  allow later to turn it to EXISTS or MAX/MIN.
 
-  RETURN
-    RES_OK     Either subquery was transformed, or appopriate
-                       predicates where injected into it.
-    RES_REDUCE The subquery was reduced to non-subquery
-    RES_ERROR  Error
+  @retval false  The subquery was transformed
+  @retval true   Error

-  Convert seconds to MYSQL_TIME value with overflow checking
-
-  SYNOPSIS:
-    sec_to_time()
-    seconds          number of seconds
-    unsigned_flag    1, if 'seconds' is unsigned, 0, otherwise
-    ltime            output MYSQL_TIME value
-
-  DESCRIPTION
-    If the 'seconds' argument is inside MYSQL_TIME data range, convert it to a
-    corresponding value.
-    Otherwise, truncate the resulting value to the nearest endpoint, and
-    produce a warning message.
-
-  RETURN
-    1                if the value was truncated during conversion
-    0                otherwise

+  3.2.2 Merged semi-joins and join optimization
+  3.3 Semi-joins and query execution
+
+  1. What is a semi-join subquery
+  -------------------------------
+  We use this definition of semi-join:
+
+    outer_tbl SEMI JOIN inner_tbl ON cond = {set of outer_tbl.row such that
+                                             exist inner_tbl.row, for which 
+                                             cond(outer_tbl.row,inner_tbl.row)
+                                             is satisfied}
+  
+  That is, semi-join operation is similar to inner join operation, with
+  exception that we don't care how many matches a row from outer_tbl has in
+  inner_tbl.
+
+  In SQL terms: a semi-join subquery is an IN subquery that is an AND-part of
+  the WHERE/ON clause.
+
+  2. General idea about semi-join execution
+  -----------------------------------------
+  We can execute semi-join in a way similar to inner join, with exception that
+  we need to somehow ensure that we do not generate record combinations that
+  differ only in rows of inner tables.
+  There is a number of different ways to achieve this property, implemented by
+  a number of semi-join execution strategies.
+  Some strategies can handle any semi-joins, other can be applied only to
+  semi-joins that have certain properties that are described below:
+
+  2.1 Correlated vs uncorrelated semi-joins
+  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+  Uncorrelated semi-joins are special in the respect that they allow to
+   - execute the subquery (possible as it's uncorrelated)
+   - somehow make sure that generated set does not have duplicates
+   - perform an inner join with outer tables.
+  
+  or, rephrasing in SQL form:
+
+  SELECT ... FROM ot WHERE ot.col IN (SELECT it.col FROM it WHERE uncorr_cond)
+    ->
+  SELECT ... FROM ot JOIN (SELECT DISTINCT it.col FROM it WHERE uncorr_cond)
+
+  2.2 Mergeable vs non-mergeable semi-joins
+  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+  Semi-join operation has some degree of commutability with inner join
+  operation: we can join subquery's tables with ouside table(s) and eliminate
+  duplicate record combination after that:
+
+    ot1 JOIN ot2 SEMI_JOIN{it1,it2} (it1 JOIN it2) ON sjcond(ot2,it*) ->
+              |
+              +-------------------------------+
+                                              v
+    ot1 SEMI_JOIN{it1,it2} (it1 JOIN it2 JOIN ot2) ON sjcond(ot2,it*)
+ 
+  In order for this to work, subquery's top-level operation must be join, and
+  grouping or ordering with limit (grouping or ordering with limit are not
+  commutative with duplicate removal). In other words, the conversion is
+  possible when the subquery doesn't have GROUP BY clause, any aggregate
+  functions*, or ORDER BY ... LIMIT clause.
+
+  Definitions:
+  - Subquery whose top-level operation is a join is called *mergeable semi-join*
+  - All other kinds of semi-join subqueries are considered non-mergeable.
+
+  *- this requirement is actually too strong, but its exceptions are too
+  complicated to be considered here.
+
+  3. Code-level view of semi-join processing
+  ------------------------------------------
+  
+  3.1 Conversion and pre-optimization data structures
+  ---------------------------------------------------
+  * When doing JOIN::prepare for the subquery, we detect that it can be
+    converted into a semi-join and register it in parent_join->sj_subselects
+
+  * At the start of parent_join->optimize(), the predicate is converted into 
+    a semi-join node. A semi-join node is a TABLE_LIST object that is linked
+    somewhere in parent_join->join_list (either it is just present there, or
+    it is a descendant of some of its members).
+  
+  There are two kinds of semi-joins:
+  - Merged semi-joins
+  - Non-merged semi-joins
+   
+  3.1.1 Merged semi-join TABLE_LIST object
+  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+  Merged semi-join object is a TABLE_LIST that contains a sub-join of 
+  subquery tables and the semi-join ON expression (in this respect it is 
+  very similar to nested outer join representation)
+  Merged semi-join represents this SQL:
+
+    ... SEMI JOIN (inner_tbl1 JOIN ... JOIN inner_tbl_n) ON sj_on_expr
+  
+  Semi-join objects of this kind have TABLE_LIST::sj_subq_pred set.
+ 
+  3.1.2 Non-merged semi-join data structure
+  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+  Non-merged semi-join object is a leaf TABLE_LIST object that has a subquery
+  that produces rows. It is similar to a base table and represents this SQL:
+    
+    ... SEMI_JOIN (SELECT non_mergeable_select) ON sj_on_expr
+  
+  Subquery items that were converted into semi-joins are removed from the WHERE
+  clause. (They do remain in PS-saved WHERE clause, and they replace themselves
+  with Item_int(1) on subsequent re-executions).
+
+  3.2 Semi-joins and join optimization
+  ------------------------------------
+  
+  3.2.1 Non-merged semi-joins and join optimization
+  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+  For join optimization purposes, non-merged semi-join nests are similar to
+  base tables - they've got one JOIN_TAB, which can be accessed with one of
+  two methods:
+   - full table scan (representing SJ-Materialization-Scan strategy)
+   - eq_ref-like table lookup (representing SJ-Materialization-Lookup)
+
+  Unlike regular base tables, non-merged semi-joins have:
+   - non-zero JOIN_TAB::startup_cost, and
+   - join_tab->table->is_filled_at_execution()==TRUE, which means one
+     cannot do const table detection or range analysis or other table data-
+     dependent inferences
+  // instead, get_delayed_table_estimates() runs optimization on the nest so that 
+  // we get an idea about temptable size
+  
+  3.2.2 Merged semi-joins and join optimization
+  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+   - optimize_semijoin_nests() does pre-optimization 
+   - during join optimization, the join has one JOIN_TAB (or is it POSITION?) 
+     array, and suffix-based detection is used, see advance_sj_state()
+   - after join optimization is done, get_best_combination() switches 
+     the data-structure to prefix-based, multiple JOIN_TAB ranges format.
+
+  3.3 Semi-joins and query execution
+  ----------------------------------
+  * Join executor has hooks for all semi-join strategies.
+    TODO elaborate.

+
+  DESCRIPTION
+    Get #output_rows and scan_time estimates for a "delayed" table. By
+    "delayed" here we mean that the table is filled at the start of query
+    execution. This means that the optimizer can't use table statistics to 
+    get #rows estimate for it, it has to call this function instead.
+
+    This function is expected to make different actions depending on the nature
+    of the table. At the moment there is only one kind of delayed tables,
+    non-flattenable semi-joins.

+  The method chooses between the materialization and IN=>EXISTS rewrite
+  strategies for the execution of a non-flattened subquery IN predicate.
+  The cost-based decision is made as follows:
+
+  1. compute materialize_strategy_cost based on the unmodified subquery
+  2. reoptimize the subquery taking into account the IN-EXISTS predicates
+  3. compute in_exists_strategy_cost based on the reoptimized plan

+  6. if (in_strategy == MATERIALIZATION)
+       revert the subquery plan to the original one before reoptimizing
+     else
+       inject the IN=>EXISTS predicates into the new EXISTS subquery plan
+
+  The implementation itself is a bit more complicated because it takes into

+  - if materialization was the cheaper strategy, whether it can be executed

+  @brief
+  Merge a derived table/view into the embedding select
+
+  @param thd     thread handle
+  @param lex     LEX of the embedding query.
+  @param derived reference to the derived table.
+
+  @details
+  This function merges the given derived table / view into the parent select
+  construction. Any derived table/reference to view occurred in the FROM
+  clause of the embedding select is represented by a TABLE_LIST structure a
+  pointer to which is passed to the function as in the parameter 'derived'.
+  This structure contains  the number/map, alias, a link to SELECT_LEX of the
+  derived table and other info. If the 'derived' table is used in a nested join
+  then additionally the structure contains a reference to the ON expression
+  for this join.
+
+  The merge process results in elimination of the derived table (or the
+  reference to a view) such that:
+    - the FROM list of the derived table/view is wrapped into a nested join
+      after which the nest is added to the FROM list of the embedding select
+    - the WHERE condition of the derived table (view) is ANDed with the ON
+      condition attached to the table.
+
+  @note
+  Tables are merged into the leaf_tables list, original derived table is removed
+  from this list also. SELECT_LEX::table_list list is left untouched.
+  Where expression is merged with derived table's on_expr and can be found after
+  the merge through the SELECT_LEX::table_list.
+
+  Examples of the derived table/view merge:
+
+  Schema:
+  Tables: t1(f1), t2(f2), t3(f3)
+  View v1: SELECT f1 FROM t1 WHERE f1 < 1
+
+  Example with a view:
+    Before merge:
+
+    The query (Q1): SELECT f1,f2 FROM t2 LEFT JOIN v1 ON f1 = f2
+
+       (LEX of the main query)
+                 |
+           (select_lex)
+                 |
+         (FROM table list)
+                 |
+            (join list)= t2, v1
+                             / \
+                            /  (on_expr)= (f1 = f2)
+                            |
+                    (LEX of the v1 view)
+                            |
+                       (select_lex)= SELECT f1 FROM t1 WHERE f1 < 1
+
+
+    After merge:
+
+    The rewritten query Q1 (Q1'):
+      SELECT f1,f2 FROM t2 LEFT JOIN (t1) ON ((f1 = f2) and (f1 < 1))
+
+        (LEX of the main query)
+                   |
+             (select_lex)
+                   |
+           (FROM table list)
+                   |
+               (join list)= t2, (t1)
+                                    \
+                                   (on_expr)= (f1 = f2) and (f1 < 1)
+
+    In this example table numbers are assigned as follows:
+      (outer select): t2 - 1, v1 - 2
+      (inner select): t1 - 1
+    After the merge table numbers will be:
+      (outer select): t2 - 1, t1 - 2
+
+  Example with a derived table:
+    The query Q2:
+      SELECT f1,f2
+       FROM (SELECT f1 FROM t1, t3 WHERE f1=f3 and f1 < 1) tt, t2
+       WHERE f1 = f2
+
+    Before merge:
+              (LEX of the main query)
+                        |
+                  (select_lex)
+                  /           \
+       (FROM table list)   (WHERE clause)= (f1 = f2)
+                  |
+           (join list)= tt, t2
+                       / \
+                      /  (on_expr)= (empty)
+                     /
+           (select_lex)= SELECT f1 FROM t1, t3 WHERE f1 = f3 and f1 < 1
+
+    After merge:
+
+    The rewritten query Q2 (Q2'):
+      SELECT f1,f2
+       FROM (t1, t3) JOIN t2 ON (f1 = f3 and f1 < 1)
+       WHERE f1 = f2
+
+              (LEX of the main query)
+                        |
+                  (select_lex)
+                  /           \
+       (FROM table list)   (WHERE clause)= (f1 = f2)
+                 |
+          (join list)= t2, (t1, t3)

-  fill derived table
-
-  SYNOPSIS
-    mysql_derived_filling()
-    thd			Thread handle
-    lex                 LEX for this thread
-    unit                node that contains all SELECT's for derived tables
-    orig_table_list     TABLE_LIST for the upper SELECT
-
-  IMPLEMENTATION
-    Derived table is resolved with temporary table. It is created based on the
-    queries defined. After temporary table is filled, if this is not EXPLAIN,
-    then the entire unit / node is deleted. unit is deleted if UNION is used
-    for derived table and node is deleted is it is a  simple SELECT.
-    If you use this function, make sure it's not called at prepare.
-    Due to evaluation of LIMIT clause it can not be used at prepared stage.
-
-  RETURN
-    FALSE  OK
-    TRUE   Error

-  DESCRIPTION
-    The function serves 3 purposes - adds fields referenced from inner
-    selects to the current select list, resolves which class to use
-    to access referenced item (Item_ref of Item_direct_ref) and fixes
-    references (Item_ref objects) to these fields.
+  @details
+    The function serves 3 purposes
+
+    - adds fields referenced from inner query blocks to the current select list
+
+    - Decides which class to use to reference the items (Item_ref or
+      Item_direct_ref)
 
-    If a field isn't already in the select list and the ref_pointer_array
+    - fixes references (Item_ref objects) to these fields.
+
+    If a field isn't already on the select list and the ref_pointer_array
     is provided then it is added to the all_fields list and the pointer to
     it is saved in the ref_pointer_array.
 
     The class to access the outer field is determined by the following rules:
-    1. If the outer field isn't used under an aggregate function
-      then the Item_ref class should be used.
-    2. If the outer field is used under an aggregate function and this
-      function is aggregated in the select where the outer field was
-      resolved or in some more inner select then the Item_direct_ref
-      class should be used.
-      It used used also if we are grouping by a subquery that refers
-      this outer field.
+
+    -#. If the outer field isn't used under an aggregate function then the
+        Item_ref class should be used.
+
+    -#. If the outer field is used under an aggregate function and this
+        function is, in turn, aggregated in the query block where the outer
+        field was resolved or some query nested therein, then the
+        Item_direct_ref class should be used. Also it should be used if we are
+        grouping by a subquery containing the outer field.
+
     The resolution is done here and not at the fix_fields() stage as
-    it can be done only after sum functions are fixed and pulled up to
-    selects where they are have to be aggregated.
+    it can be done only after aggregate functions are fixed and pulled up to
+    selects where they are to be aggregated.
+
     When the class is chosen it substitutes the original field in the
     Item_outer_ref object.
 
     After this we proceed with fixing references (Item_outer_ref objects) to
     this field from inner subqueries.
 
-  RETURN
-    TRUE  an error occured
-    FALSE ok

+  @retval true An error occured.

+  @param filter_map                Bitmap of tables whose cost/fanout are to 
+                                   be taken into account.

   Check if equality can be used in removing components of GROUP BY/DISTINCT
   
-  SYNOPSIS
-    test_if_equality_guarantees_uniqueness()
-      l          the left comparison argument (a field if any)
-      r          the right comparison argument (a const of any)
-  
-  DESCRIPTION    
-    Checks if an equality predicate can be used to take away 
-    DISTINCT/GROUP BY because it is known to be true for exactly one 
-    distinct value (e.g. <expr> == <const>).
-    Arguments must be of the same type because e.g. 
-    <string_field> = <int_const> may match more than 1 distinct value from 
-    the column. 
-    We must take into consideration and the optimization done for various 
-    string constants when compared to dates etc (see Item_int_with_ref) as
-    well as the collation of the arguments.
+  @param    l          the left comparison argument (a field if any)
+  @param    r          the right comparison argument (a const of any)
   
-  RETURN VALUE  
-    TRUE    can be used
-    FALSE   cannot be used
+  @details
+  Checks if an equality predicate can be used to take away 
+  DISTINCT/GROUP BY because it is known to be true for exactly one 
+  distinct value (e.g. <expr> == <const>).
+  Arguments must be compared in the native type of the left argument
+  and (for strings) in the native collation of the left argument.
+  Otherwise, for example,
+  <string_field> = <int_const> may match more than 1 distinct value or
+  the <string_field>.
+
+  @note We don't need to aggregate l and r collations here, because r -
+  the constant item - has already been converted to a proper collation
+  for comparison. We only need to compare this collation with field's collation.
+
+  @retval true    can be used

-  There is one problem with aliases for command-line options.
-  Plugin initialization works like this
-
-     for all plugins:
-       prepare command-line options
-       initialize command-line option variables to the default values
-       parse command line, assign values as necessary
-
-     for all plugins:
-       call the plugin initialization function
-
-  it means, we cannot have maria* and aria* command-line options to use
-  the same underlying variables - because after assigning maria* values,
-  MySQL will put there default values again preparing for parsing aria*
-  values. So, maria* values will be lost.
-
-  So, we create separate set of variables for maria* options,
-  and take both values into account in ha_maria_init().
-
-  When the command line was parsed, we patch maria* options
-  to use the same variables as aria* options so that
-  set @@maria_some_var would have the same value as @@aria_some_var
-  without forcing us to copy the values around all the time.
