Apply InnoDB snapshot innodb-5.1-2858, part 7.
A follow-up fix for Bug 38839, which exposed a pre-existing bug in the autoinc handling. Detailed revision comments: r2722 | sunny | 2008-10-04 02:48:04 +0300 (Sat, 04 Oct 2008) | 18 lines branches/5.1: This bug has always existed but was masked by other errors. The fix for bug# 38839 triggered this bug. When the offset and increment are > 1 we need to calculate the next value taking into consideration the two variables. Previously we simply assumed they were 1 particularly offset was never used. MySQL does its own calculation and that's probably why it seemed to work in the past. We would return what we thought was the correct next value and then MySQL would recalculate the actual value from that and return it to the caller (e.g., handler::write_row()). Several new tests have been added that try and catch some edge cases. The tests exposed a wrap around error in MySQL next value calculation which was filed as bug 39828. The tests will need to be updated once MySQL fix that bug. One good side effect of this fix is that dict_table_t size has been reduced by 8 bytes because we have moved the autoinc_increment field to the row_prebuilt_t structure. See review-board for a detailed discussion. rb://3
