This patch includes: - MDEV-19639 sql_mode=ORACLE: Wrong SHOW PROCEDURE output for sysvar:=expr - MDEV-19640 Wrong SHOW PROCEDURE output for SET GLOBAL sysvar1=expr, sysvar2=expr - Preparatory refactoring for MySQL WL#4179 Detailed change list: 1. Changing sp_create_assignment_lex() to accept the position in the exact query buffer instead of a "bool no_lookahead". This actually fixes MDEV-19639. In the previous reduction sp_create_assignment_lex() was called too late, when the parser went far the from beginning of the statement, so only a part of the statement got into sp_instr_stmt. 2. Generating "SET" or "SET GLOBAL" inside sp_create_assignment_instr() depending on the option type. This fixes MDEV-19640. In the previous reduction the code passed (through no_lookahead) the position of the word GLOBAL inside sp_create_assignment_lex(), which worked only for the left-most assignment. 3. Fixing the affected rules to use: - ident_cli instead of ident - ident_cli_set_usual_case instead of ident_set_usual_case 4. Changing the input parameter in: - LEX::set_system_variable() - LEX::call_statement_start() - LEX::set_variable() from just LEX_CSTRING to Lex_ident_sys_st for stricter data type constrol: to make sure that noone passes an ident_cli (a fragment of the original query in the client character set) instead of server-side identifier (utf8 identifier allocated on THD when needed). 5. Adding Lex_ident_sys() in places where the affected functions are called. 6. Moving all calls of sp_create_assignment_lex() to the places just before parsing set_expr_or_default. This makes the grammar clearer, because sp_create_assignment_lex() and sp_create_assignment_instr() now stay near each other, so the balance of LEX's push/pop can be read easier. This will also help to WL#4179. 7. Adding class sp_lex_set_var Moving the initialization code from sp_create_assignment_lex() to the constructor of sp_lex_set_var. This will also help to WL#4179. 8. Moving a part of the "set" grammar rule into a separate rule "set_param". This makes the grammar easier to read and removes one shift/reduce conflict. |

MariaDB: drop-in replacement for MySQL
MariaDB is designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.
MariaDB is brought to you by the MariaDB Foundation and the MariaDB corporation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.
MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Corporation, the MariaDB Foundation and by many people in the community.
MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.
A description of the MariaDB project and a manual can be found at:
https://mariadb.com/kb/en/mariadb-vs-mysql-features/
https://mariadb.com/kb/en/mariadb-versus-mysql-compatibility/
https://mariadb.com/kb/en/library/new-and-old-releases/
As MariaDB is a full replacement of MySQL, the MySQL manual at http://dev.mysql.com/doc is generally applicable.
Help
More help is available from the Maria Discuss mailing list https://launchpad.net/~maria-discuss and the #maria IRC channel on Freenode.
Live QA for beginner contributors
MariaDB has a dedicated time each week when we answer new contributor questions live on Zulip and IRC. From 8:00 to 10:00 UTC on Mondays, and 10:00 to 12:00 UTC on Thursdays, anyone can ask any questions they’d like, and a live developer will be available to assist.
New contributors can ask questions any time, but we will provide immediate feedback during that interval.
