During import, if cfg file is not specified, we don't update the autoinc field in innodb dictionary object dict_table_t. The next insert tries to insert from the starting position of auto increment and fails. It can be observed that the issue is resolved once server is restarted as the persistent value is read correctly from PAGE_ROOT_AUTO_INC from index root page. The patch fixes the issue by reading the the auto increment value directly from PAGE_ROOT_AUTO_INC during import if cfg file is not specified. Test Fix: 1. import_bugs.test: Embedded mode warning has absolute path. Regular expression replacement in test. 2. full_crc32_import.test: Table level auto increment mismatch after import. It was using the auto increment data from the table prior to discard and import which is not right. This value has cached auto increment value higher than the actual inserted value and value stored in PAGE_ROOT_AUTO_INC. Updated the result file and added validation for checking the maximum value of auto increment column.
