Bug #38839: auto increment does not work properly with InnoDB after update Detailed revision comments: r2609 | sunny | 2008-08-24 01:19:05 +0300 (Sun, 24 Aug 2008) | 12 lines branches/5.1: Fix for MySQL Bug#38839. Reset the statement level last value field in prebuilt. This field tracks the last value in an autoincrement interval. We use this value to check whether we need to update a table's AUTOINC counter, if the value written to a table is less than this value then we avoid updating the table's AUTOINC value in order to reduce mutex contention. If it's not reset (e.g., after a DELETE statement) then there is the possibility of missing updates to the table's AUTOINC counter resulting in a subsequent duplicate row error message under certain conditions (see the test case for details).
