This bug in Field_string::cmp resulted in a wrong comparison with keys in partial indexes over multi-byte character fields. Given field a is declared as a varchar(16) collate utf8_unicode_ci INDEX(a(4)) gives us an example of such an index. Wrong key comparisons could lead to wrong result sets if the selected query execution plan used a range scan by a partial index over a utf8 character field. This also caused wrong results in many other cases.

functions in queries Using MAX()/MIN() on table with disabled indexes (by ALTER TABLE) results in error 124 (wrong index) from storage engine. The problem was that optimizer use disabled index to optimize MAX()/MIN(). Normally it must skip disabled index and perform table scan. This patch skips disabled indexes for min/max optimization.

The length of the prefix of the pattern string in the LIKE predicate that determined the index range to be scanned was calculated incorrectly for multi-byte character sets. As a result of this in 4. 1 the the scanned range was wider then necessary if the prefix contained not only one-byte characters. In 5.0 additionally it caused missing some rows from the result set.

tables Currently in INSERT ... SELECT ... LIMIT ... the compiler uses a temporary table to store the results of SELECT ... LIMIT .. and then uses that table as a source for INSERT. The problem is that in some cases it actually skips the LIMIT clause in doing that and materializes the whole SELECT result set regardless of the LIMIT. This fix is limiting the process of filling up the temp table with only that much rows that will be actually used by propagating the LIMIT value.

Certain updates of table joined to self results in unexpected behavior. The problem was that record cache was mistakenly enabled for self-joined table updates. Normally record cache must be disabled for such updates. Fixed wrong condition in code that determines whether to use record cache for self-joined table updates. Only MyISAM tables were affected.
