ChangeSet@stripped, 2007-04-26 02:01:23+05:00, gshchepa@stripped +3 -0
Fixed bug #27650:
INSERT into InnoDB table may cause "ERROR 1062 (23000): Duplicate entry..."
errors or lost records after multi-row INSERT of the form:
"INSERT INTO t (id...) VALUES (NULL...) ON DUPLICATE KEY UPDATE id=VALUES(id)",
where "id" is an AUTO_INCREMENT column.
It happens because InnoDB handler forgets to save next insert id after
updating of auto_increment column with new values. As result of that
last insert id stored inside InnoDB dictionary tables differs from it's
cached thd->next_insert_id value.
mysql-test/r/innodb_mysql.result@stripped, 2007-04-26 02:01:11+05:00, gshchepa@stripped +39 -0
Added a test case for bug #27650.
mysql-test/t/innodb_mysql.test@stripped, 2007-04-26 02:00:53+05:00, gshchepa@stripped +47 -0
Added a test case for bug #27650.

ha_innobase::write_row() function has been corrected.
# This is a BitKeeper patch. What follows are the unified diffs for the
# set of deltas contained in the patch. The rest of the patch, the part
