Fixed a bug : if you created a column prefix secondary
index and updated it so that the last characters in the
column prefix were spaces, InnoDB would assert in
row0upd.c, line 713. The same assertion
failed if you updated a column in an ordinary secondary
index so that the new value was alphabetically equivalent,
but had a different length. This could happen, for example,
in the utf-8 character set if you updated a letter to its
accented or umlaut form.
Fixed a bug : InnoDB could think that a secondary index record was not locked though it had been updated to an alphabetically equivalent value, e.g., 'abc' -> 'aBc'.
Fixed a bug : if you updated a secondary index column to an alphabetically equivalent value, and rolled back your update, InnoDB failed to restore the field in the secondary index to its original value.
There are still several outstanding non-critical bugs reported in the MySQL bugs database. Their fixing has been delayed, because resources were allocated to the 4.1.1 release.
