to detect the end of SP definition correctly we need to know where the parser stopped parsing the SP. lip->get_cpp_ptr() shows the current parsing position, lip->get_cpp_tok_start() shows the start of the last parsed token. The actual value depends on whether the parser has performed a look-ahead. For example, in CREATE PROCEDURE ... BEGIN ... END ; the parser reads 'END' and knows that this ends the procedure definition, it does not need to read the next token for this. But in CREATE PROCEDURE ... SELECT 1 ; the parser cannot know that the procedure ends at '1'. It has to read the semicolon first (it could be '1 + 2' for example). In the first case, the "current parsing position" is after END, before the semicolon, in the second case it's *after* the semicolon. Note that SP definition in both cases ends before the semicolon. To be able to detect the end of SP deterministically, we need the parser to do the look-ahead always or never. The bug fix introduces a new parser token FORCE_LOOKAHEAD. Lexer never returns it, so this token can never match. But the parser cannot know it so it will have to perform a look-ahead to determine that the next token is not FORCE_LOOKAHEAD. This way we deterministically end SP parsing with a look-ahead. |

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. 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 Foundation and the MariaDB Corporation, 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-features/
https://mariadb.com/kb/en/mariadb-versus-mysql-compatibility/
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.
