Adding support for the ROW data type in the stored function RETURNS clause: - explicit ROW(..members...) for both sql_mode=DEFAULT and sql_mode=ORACLE CREATE FUNCTION f1() RETURNS ROW(a INT, b VARCHAR(32)) ... - anchored "ROW TYPE OF [db1.]table1" declarations for sql_mode=DEFAULT CREATE FUNCTION f1() RETURNS ROW TYPE OF test.t1 ... - anchored "[db1.]table1%ROWTYPE" declarations for sql_mode=ORACLE CREATE FUNCTION f1() RETURN test.t1%ROWTYPE ... Adding support for anchored scalar data types in RETURNS clause: - "TYPE OF [db1.]table1.column1" for sql_mode=DEFAULT CREATE FUNCTION f1() RETURNS TYPE OF test.t1.column1; - "[db1.]table1.column1" for sql_mode=ORACLE CREATE FUNCTION f1() RETURN test.t1.column1%TYPE; Details: - Adding a new sql_mode_t parameter to sp_head::create() sp_head::sp_head() sp_package::create() sp_package::sp_package() to guarantee early initialization of sp_head::m_sql_mode. Before this change, this member was not initialized at all during CREATE FUNCTION/PROCEDURE/PACKAGE statements, and was not used. Now it needs to be initialized to write properly the mysql.proc.returns column, according to the create time sql_mode. - Code refactoring to make the things simpler and functions smaller: * Adding a new method Field_row::row_create_fields(THD *thd, List<Spvar_definition> *list) to make a Virtual_tmp_table with Fields for ROW members from an explicit definition. * Adding a new method Field_row::row_create_fields(THD *thd, const Spvar_definition &def) to make a Virtual_tmp_table with Fields for ROW members from an explicit or a table anchored definition. * Adding a new method Item_args::add_array_of_item_field(THD *thd, const Virtual_tmp_table &vtable) to create and array of Item_field corresponding to all Field instances in a Virtual_tmp_table * Removing Item_field_row::row_create_items(). It was decomposed into the new methods described above. * Moving the code from the loop body in sp_rcontext::init_var_items() into a separate method Spvar_definition::make_item_field_row(), to make the code clearer (smaller functions). make_item_field_row() itself uses the new methods described above. - Changing the data type of sp_head::m_return_field_def from Column_definition to Spvar_definition. So now it supports not only SQL column field types, but also explicit ROW and anchored ROW data types, as well as anchored column types. - Adding a new Column_definition parameter to sp_head::create_result_field(). Before this patch, create_result_field() took the definition only from m_return_field_def. Now it's also called with a local Column_definition variable which contains the explicit definition resolved from an anchored defition. - Modifying sql_yacc.yy to support the new grammar. Adding new helper methods: * sf_return_fill_definition_row() * sf_return_fill_definition_rowtype_of() * sf_return_fill_definition_type_of() - Fixing tests in: * Virtual_tmp_table::setup_field_pointers() in sql_select.cc * Send_field::normalize() in field.h * store_column_type() to prevent calling Type_handler_row::field_type(), which is implemented a DBUG_ASSERT(0). Before this patch the affected methods and functions were called only for scalar data types. Now ROW is also possible. - Adding a new virtual method Field::cols() - Overriding methods: Item_func_sp::cols() Item_func_sp::element_index() Item_func_sp::check_cols() Item_func_sp::bring_value() to support the ROW data type. - Extending the rule sp_return_type to support * explicit ROW and anchored ROW data types * anchored scalar data types - Overriding Field_row::sql_type() to print the data type of an explicit ROW. |

This directory contains test suites for the MariaDB server. To run currently existing test cases, execute ./mysql-test-run in this directory. Some tests are known to fail on some platforms or be otherwise unreliable. In the file collections/smoke_test there is a list of tests that are expected to be stable. In general you do not have to do "make install", and you can have a co-existing MariaDB installation, the tests will not conflict with it. To run the tests in a source directory, you must do "make" first. In Red Hat distributions, you should run the script as user "mysql". The user is created with nologin shell, so the best bet is something like # su - # cd /usr/share/mariadb-test # su -s /bin/bash mysql -c ./mysql-test-run This will use the installed MariaDB executables, but will run a private copy of the server process (using data files within /usr/share/mariadb-test), so you need not start the mysqld service beforehand. You can omit --skip-test-list option if you want to check whether the listed failures occur for you. To clean up afterwards, remove the created "var" subdirectory, e.g. # su -s /bin/bash - mysql -c "rm -rf /usr/share/mariadb-test/var" If tests fail on your system, please read the following manual section for instructions on how to report the problem: https://mariadb.com/kb/en/reporting-bugs If you want to use an already running MySQL server for specific tests, use the --extern option to mysql-test-run. Please note that in this mode, you are expected to provide names of the tests to run. For example, here is the command to run the "alias" and "analyze" tests with an external server: # mariadb-test-run --extern socket=/tmp/mysql.sock alias analyze To match your setup, you might need to provide other relevant options. With no test names on the command line, mysql-test-run will attempt to execute the default set of tests, which will certainly fail, because many tests cannot run with an external server (they need to control the options with which the server is started, restart the server during execution, etc.) You can create your own test cases. To create a test case, create a new file in the main subdirectory using a text editor. The file should have a .test extension. For example: # xemacs t/test_case_name.test In the file, put a set of SQL statements that create some tables, load test data, and run some queries to manipulate it. Your test should begin by dropping the tables you are going to create and end by dropping them again. This ensures that you can run the test over and over again. If you are using mysqltest commands in your test case, you should create the result file as follows: # mariadb-test-run --record test_case_name or # mariadb-test --record < t/test_case_name.test If you only have a simple test case consisting of SQL statements and comments, you can create the result file in one of the following ways: # mariadb-test-run --record test_case_name # mariadb test < t/test_case_name.test > r/test_case_name.result # mariadb-test --record --database test --result-file=r/test_case_name.result < t/test_case_name.test When this is done, take a look at r/test_case_name.result. If the result is incorrect, you have found a bug. In this case, you should edit the test result to the correct results so that we can verify that the bug is corrected in future releases. If you want to submit your test case you can send it to developers@lists.mariadb.org or attach it to a bug report on http://mariadb.org/jira/. If the test case is really big or if it contains 'not public' data, then put your .test file and .result file(s) into a tar.gz archive, add a README that explains the problem, ftp the archive to ftp://ftp.mariadb.org/private and submit a report to https://mariadb.org/jira about it.
