create table t1 (a smallint primary key auto_increment); insert into t1 values(32767); insert into t1 values(NULL); ERROR 1062 (23000): Duplicate entry '32767' for key 'PRIMARY Now on always gets error HA_ERR_AUTOINC_RANGE=167 "Out of range value for column", independent of store engine, SQL Mode or number of inserted rows. This is an unique error that is easier to test for in replication. Another bug fix is that we now get an error when trying to insert a too big auto-generated value, even in non-strict mode. Before one get insted the max column value inserted. This patch also fixes some issues with inserting negative numbers in an auto-increment column. Fixed the ER_DUP_ENTRY and HA_ERR_AUTOINC_ERANGE are compared the same between master and slave. This ensures that replication works between an old server to a new slave for auto-increment overflow errors. Added SQLSTATE errors for handler errors Smaller bug fixes: * Added warnings for duplicate key errors when using INSERT IGNORE * Fixed bug when using --skip-log-bin followed by --log-bin, which did set log-bin to "0" * Allow one to see how cmake is called by using --just-print --just-configure BUILD/FINISH.sh: --just-print --just-configure now shows how cmake would be invoked. Good for understanding parameters to cmake. cmake/configure.pl: --just-print --just-configure now shows how cmake would be invoked. Good for understanding parameters to cmake. include/CMakeLists.txt: Added handler_state.h include/handler_state.h: SQLSTATE for handler error messages.
