led to creating corrupted index. While execution of the CREATE .. SELECT SQL_BUFFER_RESULT statement the engine->start_bulk_insert function was called twice. On the first call On the first call MyISAM disabled all non-unique indexes and on the second call it decides to not re-enable them because all indexes was disabled. Due to this no indexes was actually created during CREATE TABLE thus producing crashed table. Now the select_inset class has is_bulk_insert_mode flag which prevents calling the start_bulk_insert function twice. The flag is set in the select_create::prepare, select_insert::prepare2 functions and the select_insert class constructor. The flag is reset in the select_insert::send_eof function. mysql-test/t/insert_select.test: A test case is added for the bug#30384: Having SQL_BUFFER_RESULT option in the CREATE .. KEY(..) .. SELECT led to creating corrupted index. mysql-test/r/insert_select.result: A test case is added for the bug#30384: Having SQL_BUFFER_RESULT option in the CREATE .. KEY(..) .. SELECT led to creating corrupted index. sql/sql_class.h: Bug#30384: Having SQL_BUFFER_RESULT option in the CREATE .. KEY(..) .. SELECT led to creating corrupted index. The is_bulk_insert_mode flag is added to the select_insert class. sql/sql_insert.cc: Bug#30384: Having SQL_BUFFER_RESULT option in the CREATE .. KEY(..) .. SELECT led to creating corrupted index. The is_bulk_insert_mode is set in the select_create::prepare, select_insert::prepare2 functions and the select_insert class constructor. The flag is reset in the select_insert::send_eof function. |
