From df5e20e75d18d705700480d777d6e0b2fed45d2c Mon Sep 17 00:00:00 2001
From: "tsmith@production.mysql.com" <>
Date: Tue, 15 Aug 2006 01:42:57 +0200
Subject: [PATCH 1/3] Applied innodb-5.1-ss677, -ss680, -ss713, and -ss720
 snapshots. All but ss677 are against the mysql-5.1 tree only.

Fixes the following bugs:
- Bug #19834: Using cursors when running in READ-COMMITTED can cause InnoDB to crash
- Bug #20213: DBT2 testing cause mysqld to core using Innodb
- Bug #20493: on partition tables, select and show command casue server crash
- Bug #21113: Duplicate printout in SHOW INNODB STATUS
- Bug #21313: rsql_..._recover_innodb_tmp_table is redundant and broken
- Bug #21467: Manual URL wrong in InnoDB "page corrupted" error report
