Bug#35335 funcs_1: Some tests fail within load_file during pushbuild runs Solution: 1. Move files with input data used in load_file, load data etc. from suite/funcs_1/<whatever> to std_data 2. Use for testsuite funcs_1 the server option --secure-file-priv=<MYSQLTEST_VARDIR> 3. Outfiles have to be stored under MYSQLTEST_VARDIR + changes according to WL#4304 Cleanup in funcs_1 tests - backport of fixes/improvements made in 5.1 to 5.0 The differences between scripts in 5.0 and 5.1 cause much additional and annoying work during any upmerge. - replace error numbers with names - improved comments - improved formatting - Unify storage engine names so that result files for storage engine variants do not differ (some tests) - remove a script no more used (tests are done in other scripts) BitKeeper/deleted/.del-triggers_master.test: Delete:

The problem was that LOAD DATA code (sql_load.cc) didn't take into account that there may be items, representing references to other columns. This is a usual case in views. The crash happened because Item_direct_view_ref was casted to Item_user_var_as_out_param, which is not a base class. The fix is to 1) Handle references properly; 2) Ensure that an item is treated as a user variable only when it is a user variable indeed; 3) Report an error if LOAD DATA is used to load data into non-updatable column. mysql-test/r/loaddata.result: Update result file. mysql-test/t/loaddata.test: Add a test case form Bug#35469: server crash with LOAD DATA INFILE to a VIEW. sql/share/errmsg.txt: Introduce a new error. sql/sql_load.cc: Handle reference-items properly. mysql-test/std_data/bug35649.data: Add a data file for the test case.

Mixing aggregate functions and non-grouping columns is not allowed in the ONLY_FULL_GROUP_BY mode. However in some cases the error wasn't thrown because of insufficient check. In order to check more thoroughly the new algorithm employs a list of outer fields used in a sum function and a SELECT_LEX::full_group_by_flag. Each non-outer field checked to find out whether it's aggregated or not and the current select is marked accordingly. All outer fields that are used under an aggregate function are added to the Item_sum::outer_fields list and later checked by the Item_sum::check_sum_func function. mysql-test/t/group_by.test: Added a test case for the bug#27219: Aggregate functions in ORDER BY. mysql-test/r/group_by.result: Added a test case for the bug#27219: Aggregate functions in ORDER BY. sql/sql_select.cc: Bug#27219: Aggregate functions in ORDER BY.

Initialization of the full_group_by_flag bitmap. SELECT_LEX::test_limit function doesn't reset ORDER BY clause anymore. sql/sql_lex.h: Bug#27219: Aggregate functions in ORDER BY.

The Item_in_subselect::select_in_like_transformer function now drops ORDER BY clause in all selects in a subquery. sql/item_sum.cc: Bug#27219: Aggregate functions in ORDER BY. Now the Item_sum::check_sum_func function now checks whether fields in the outer_fields list are aggregated or not and marks selects accordingly. sql/item.cc: Bug#27219: Aggregate functions in ORDER BY. Now the Item_field::fix_fields function checks whether the field is aggregated or not and marks its select_lex accordingly.

Bug#21413 "Engine table handler used by multiple threads in REPLACE DELAYED" When executing a REPLACE DELAYED statement, the storage engine ::extra() method was invoked by a different thread than the thread which has acquired the handler instance. This did not cause problems within the current server and with the current storage engines. But it has the potential to confuse future storage engines. Added code to avoid surplus calls to extra() method in case of DELAYED which avoids calling storage engine from a different thread than expected. No test case. This change does not change behavior in conjunction with current storage engines. So it cannot be tested by the regression test suite. sql/sql_insert.cc: Bug#21413 When performing DELAYED operations, we should not call the storage engine methods from the 'wrong' context. Ensure that the calls to the methods are appropiately guarded by either moving calls to sections where the lock_type is checked. No need to copy all elements of TABLE_LIST when opening table using open_ltable().

View definition as SELECT ... FROM DUAL WHERE ... has valid syntax, but use of such view in SELECT or SHOW CREATE VIEW syntax causes unexpected syntax error. Server omits FROM DUAL clause when storing view body string in a .frm file for further evaluation. However, syntax of SELECT-witout-FROM query is more restrictive than SELECT FROM DUAL syntax, and doesn't allow the WHERE clause. NOTE: this syntax difference is not documented. View registration procedure has been modified to preserve original structure of view's body. mysql-test/r/view.result: Added test case for bug #35193. mysql-test/t/view.test: Added test case for bug #35193. sql/sql_select.cc: Fixed bug #35193. The st_select_lex::print function always omits FROM DUAL clause, even if original SELECT query has the WHERE clause. The mysql_register_view function uses this function to reconstruct a body of view's AS clause for further evaluation and stores that reconstructed clause in a .frm file. SELECT without FROM syntax is more restrictive than SELECT FROM DUAL syntax: second one allows the WHERE clause, but first one is not. Use of this view in SELECT or SHOW CREATE VIEW queries causes unexpected syntax errors. The st_select_lex::print function has been modified to reconstruct FROM DUAL clause in queries when needed. TODO: Syntax difference is not documented and should be eliminated, however improvement of the SELECT-without-FROM syntax is not trivial and leads to significant modification of grammar file because of additional shift/reduce conflicts.
