Applied the fix for bug #47217 from the mysql-6.0 codebase. The patch adds not null predicates generated for the left parts of the equality predicates used for ref accesses. This is done for such predicates both in where conditions and on conditions. For the where conditions the not null predicates were generated but in 5.0/5.1 they actually never were used due to some lame merge from 4.1 to 5.0. The fix for bug #47217 made these predicates to be used in the condition pushed to the tables. Yet only this patch generates not null predicates for equality predicated from on conditions of outer joins. This patch introduces a performance regression that can be observed on a test case from null_key.test. The regression will disappear after the fix for bug #57024 from mariadb-5.1 is pulled into mariadb-5.3. The patch contains many changes in the outputs of the EXPLAIN commands since generated not null predicates are considered as parts of the conditions pushed to join tables and may add 'Usingwhere' in some rows of EXPLAINs where there used to be no such comments.

The problem was in an incorrect debug assertion. The expression used in the failing assertion states that when finding references matching ORDER BY expressions, there can be only one reference to a single table. But that does not make any sense, all test cases for this bug are valid examples with multiple identical WHERE expressions referencing the same table which are also present in the ORDER BY list. Fixed by removing the failing assertion. We also have to take care of the 'found' counter so that we count multiple references only once. We rely on this fact later in eq_ref_table(). mysql-test/r/join.result: Added a test case for bug #50335. mysql-test/t/join.test: Added a test case for bug #50335. sql/sql_select.cc: Removing the assertion in eq_ref_table() as it does not make any sense. We also have to take care of the 'found' counter so that we count multiple references only once. We rely on this fact later in eq_ref_table().

The crash is the result of an attempt made by JOIN::optimize to evaluate the WHERE condition when no records have been actually read. The fix is to remove erroneous 'outer_join' variable check. mysql-test/r/join.result: test result mysql-test/t/join.test: test case sql/sql_select.cc: removed erroneous 'outer_join' variable check.

The crash happens because greedy_serach can not determine best plan due to wrong inner table dependences. These dependences affects join table sorting which performs before greedy_search starting. In our case table which has real 'no dependences' should be put on top of the list but it does not happen as inner tables have no dependences as well. The fix is to exclude RAND_TABLE_BIT mask from condition which checks if table dependences should be updated. mysql-test/r/join.result: test result mysql-test/t/join.test: test case sql/sql_select.cc: RAND_TABLE_BIT mask should not be counted as it prevents update of inner table dependences. For example it might happen if RAND() function is used in JOIN ON clause.

The problem becomes apparent only if HAVE_purify is undefined. It related to the part of code placed in open_table_from_share() fuction where we initialize record buffer only if HAVE_purify is enabled. So in case of HAVE_purify=OFF record buffer is not initialized on open table stage. Next we read key, find NULL value and update appropriate null bit but do not update record buffer. After that the record is stored in the join cache(store_record_in_cache). For CHAR fields we strip trailing spaces and in our case this procedure uses uninitialized record buffer. The fix is to skip stripping space procedure in case of null values for CHAR fields(partially based on 6.0 JOIN_CACHE implementation). mysql-test/r/join.result: test case mysql-test/t/join.test: test case sql/field.cc: code updated according to new CACHE_FIELD struct sql/sql_select.cc: code updated according to new CACHE_FIELD struct sql/sql_select.h: CACHE_FIELD struct: added new fields: Field *field, uint type; removed fields: Field_blob *blob_field, bool strip;

WL#2474 "Multi Range Read: Change the default MRR implementation to implement new MRR interface" WL#2475 "Batched range read functions for MyISAM/InnoDb" "Index condition pushdown for MyISAM/InnoDB" Igor's fix from sp1r-igor@olga.mysql.com-20080330055902-07614: There could be observed the following problems: 1. EXPLAIN did not mention pushdown conditions from on expressions in the 'extra' column. As a result if a query had no where conditions pushed down to a table, but had on conditions pushed to this table the 'extra' column in the EXPLAIN for the table missed 'using where'. 2. Conditions for ref access were not eliminated from on expressions though such conditions were eliminated from the where condition.

Queries with nested outer joins may lead to crashes or bad results because an internal data structure is not handled correctly. The optimizer uses bitmaps of nested JOINs to determine if certain table can be placed at a certain place in the JOIN order. It does maintain a bitmap describing in which JOINs last placed table is nested. When it puts a table it makes sure the bit of every JOIN that contains the table in question is set (because JOINs can be nested). It does that by recursively setting the bit for the next enclosing JOIN when this is the first table in the JOIN and recursively resetting the bit if it's the last table in the JOIN. When it removes a table from the join order it should do the opposite : recursively unset the bit if it's the only remaining table in this join and and recursively set the bit if it's removing the last table of a JOIN. There was an error in how the bits was set for the upper levels : when removing a table it was setting the bit for all the enclosing nested JOINs even if there were more tables left in the current JOIN (which practically means that the upper nested JOINs were not affected). Fixed by stopping the recursion at the relevant level. mysql-test/r/join.result: Bug #42116: test case mysql-test/t/join.test: Bug #42116: test case sql/sql_select.cc: Bug #41116: don't go up and set the bits if more tables in at the current JOIN level

The bug is not related to MERGE table or TRIGGER. More correct description would be 'assertion on multi-table UPDATE + NATURAL JOIN + MERGEABLE VIEW'. On PREPARE stage(see test case) we call mark_common_columns() func which creates ON condition for NATURAL JOIN and sets appropriate table read_set bitmaps for fields which are used in ON condition. On EXECUTE stage mark_common_columns() is not called, we set necessary read_set bitmaps in setup_conds(). But 'B.f1' field is already processed and related item alredy fixed before setup_conds() as updated field and setup_conds can not set read_set bitmap because of that. The fix is to set read_set bitmap for appropriate table field even if Item_direct_view_ref item which represents a refernce to this field is fixed. mysql-test/r/join.result: test result mysql-test/t/join.test: test case sql/item.cc: The bug is not related to MERGE table or TRIGGER.

A rule was introduced by the 5.1 part of the fix for bug 27531 to prefer filesort over indexed ORDER BY when accessing all of the rows of a table (because it's faster). This new rule was not accounting for the presence of a LIMIT clause. Fixed the condition for this rule so it will prefer filesort over indexed ORDER BY only if no LIMIT. mysql-test/r/compress.result: Bug #31094: LIMIT is not considered a full index scan mysql-test/r/join.result: Bug #31094: test case mysql-test/r/select.result: Bug #31094: LIMIT is not considered a full index scan mysql-test/r/ssl.result: Bug #31094: LIMIT is not considered a full index scan mysql-test/r/ssl_compress.result: Bug #31094: LIMIT is not considered a full index scan mysql-test/t/join.test: Bug #31094: test case sql/sql_select.cc: Bug #31094: prefer filesort over indexed ORDER BY only if no LIMIT

When checking for applicability of join cache we must disable its usage only if there is no temp table in use. When a temp table is used we can use join cache (and it will not make the result-set unordered) to fill the temp table. The filesort() operation is then applied to the data in the temp table and hence is not affected by join cache usage. Fixed by narrowing the condition for disabling join cache to exclude the case where temp table is used. mysql-test/r/join.result: Bug #27531: test case mysql-test/t/join.test: Bug #27531: test case sql/sql_select.cc: Bug #27531: Disable join cache only if not using temp table

query Problem: There was a wrong context assigned to the columns that were added in insert_fields() when expanding a '*'. When this is done in a prepared statement it causes fix_fields() to fail to find the table that these columns reference. Actually the right context is set in setup_natural_join_row_types() called at the end of setup_tables(). However when executed in a context of a prepared statement setup_tables() resets the context, but setup_natural_join_row_types() was not setting it to the correct value assuming it has already done so. Solution: The top-most, left-most NATURAL/USING join must be set as a first_name_resolution_table in context even when operating on prepared statements. mysql-test/r/join.result: testsuite for the bug mysql-test/t/join.test: testsuite for the bug sql/sql_base.cc: The context must be set even when executed as prepared statement.

The cause of this bug was a design flaw due to which the list of natural join columns was incorrectly computed and stored for nested joins that are not natural joins, but are operands (possibly indirect) of nested joins. The patch corrects the flaw in a such a way, that the result columns of a table reference are materialized only if it is a leaf table (that is, only if it is a view, stored table, or natural/using join). mysql-test/r/join.result: Added test for BUG#15229 and uncommented failing test cases of BUG#15357 (now fixed by this patch). mysql-test/t/join.test: Added test for BUG#15229 and uncommented failing test cases of BUG#15357 (now fixed by this patch). sql/sql_base.cc: - Do not materialize the result columns of regular nested joins (that are not natural/using joins). - Moved most of the code that creates/adds new natural join column references to the method 'get_or_create_column_ref', and simplified 'mark_common_columns'. - Replaced a call to 'get_or_create_column_ref' with 'get_natural_column_ref' where it is for sure all columns are alredy created. sql/table.cc: - Modified the method 'get_or_create_column_ref' so that it adds itself the newly created natural join columns to the respective table reference. sql/table.h: - Modified the method 'get_or_create_column_ref' so that it adds itself the newly created natural join columns to the respective table reference.

The cause of the bug was an ASSERT that checked the consistency of TABLE_SHARE::db and TABLE_LIST::db and failed for I_S tables. The fix relaxes the requirement for consistency for I_S. mysql-test/r/join.result: Added test for BUG#17523 mysql-test/t/join.test: Added test for BUG#17523 sql/table.cc: Take into account that for I_S tables, TABLE_SHARE::db == 0, while TABLE_LIST::db contains the database name of a table. The only change is in the ASSERTs.

* Provide backwards compatibility extension to name resolution of coalesced columns. The patch allows such columns to be qualified with a table (and db) name, as it is in 4.1. Based on a patch from Monty. * Adjusted tests accordingly to test both backwards compatible name resolution of qualified columns, and ANSI-style resolution of non-qualified columns. For this, each affected test has two versions - one with qualified columns, and one without. mysql-test/include/ps_query.inc: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/bdb.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/innodb.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/join.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/join_nested.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/join_outer.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/null_key.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/order_by.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/ps_2myisam.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/ps_3innodb.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/ps_4heap.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/ps_5merge.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/ps_6bdb.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/ps_7ndb.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/select.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/subselect.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/r/type_ranges.result: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/t/bdb.test: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/t/innodb.test: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/t/join.test: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/t/join_nested.test: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/t/join_outer.test: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/t/null_key.test: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/t/order_by.test: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/t/select.test: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/t/subselect.test: Put back old tests to test that coalesced columns of natural joins can be qualified. mysql-test/t/type_ranges.test: Put back old tests to test that coalesced columns of natural joins can be qualified. sql/sql_base.cc: * Applied Monty's patch for backwards compatible name resolution of qualified columns. The idea is: - When a column is qualified, search for the column in all tables/views underlying each natural join. In this case natural joins are *not* considered leaves. - If a column is not qualified, then consider natural joins as leaves, thus directly search the result columns of natural joins. * Simplified 'find_field_in_tables()' - unified two similar loops into one. sql/table.cc: - Removed method & members not needed after Monty's patch. sql/table.h: - Removed method & members not needed after Monty's patch. tests/mysql_client_test.c: Put back old tests to test that coalesced columns of natural joins can be qualified.

"Process NATURAL and USING joins according to SQL:2003". * Some of the main problems fixed by the patch: - in "select *" queries the * expanded correctly according to ANSI for arbitrary natural/using joins - natural/using joins are correctly transformed into JOIN ... ON for any number/nesting of the joins. - column references are correctly resolved against natural joins of any nesting and combined with arbitrary other joins. * This patch also contains a fix for name resolution of items inside the ON condition of JOIN ... ON - in this case items must be resolved only against the JOIN operands. To support such 'local' name resolution, the patch introduces a stack of name resolution contexts used at parse time. NOTICE: - This patch is not complete in the sense that - there are 2 test cases that still do not pass - one in join.test, one in select.test. Both are marked with a comment "TODO: WL#2486". - it does not include a new test specific for the task mysql-test/include/ps_query.inc: Adjusted according to standard NATURAL/USING join semantics., mysql-test/r/bdb.result: Adjusted according to standard NATURAL/USING join semantics. mysql-test/r/derived.result: Adjusted according to standard NATURAL/USING join semantics. mysql-test/r/errors.result: The column as a whole cannot be resolved, so different error message. mysql-test/r/fulltext.result: Adjusted according to standard JOIN ...

The entry point to processing NATURAL/USING joins is the procedure 'setup_natural_join_row_types'. - Replaced the specialized Field_iterator_XXX iterators with one generic iterator over the fields of a table reference. - Simplified 'insert_fields' and 'setup_conds' due to encapsulation of the processing of natural joins in a separate set of procedures. sql/sql_class.h: - Commented old code. sql/sql_delete.cc: - Pass the FROM clause to setup_tables. sql/sql_help.cc: - pass the end name resolution table to find_field_in_tables - adjust the list of tables for name resolution sql/sql_insert.cc: - Changed the code that saves and restores the current context to support the list of tables for name resolution - context->first_name_resolution_table, and table_list->next_name_resolution_table.

This is not valid if inner tables return an empty set. Setting dependency on outer tables was added for the above cases. To fix the crash in the test case of bug #4976 a guard was added that blocks running the crashing code for nested outer joins. sql/sql_select.cc: The previous fix for bug 4976 was reversed as it erroniously converted an outer join into an innner join when on_expression does not refer to outer tables.
