CHECK TABLE could complain about a fully intact spatial index.
A wrong comparison operator was used for table checking. 
The result was that it checked for non-matching spatial keys. 
This succeeded if at least two different keys were present, 
but failed if only the matching key was present.

I fixed the key comparison.

Produce a warning if DATA/INDEX DIRECTORY is specified in
ALTER TABLE statement.

Ignoring of these options is documented in the symbolic links
section of the manual.

  An UNIQUE KEY consisting of NOT NULL columns
  was displayed as PRIMARY KEY in "DESC t1".
  According to the code, that was intentional
  behaviour for some reasons unknown to me.
  This code was written before bitkeeper time,
  so I cannot check who and why made this.
  After discussing on dev-public, a decision
  was made to remove this code

  Disable the simplistic auto dependency scan for test/bench (bug#20078)

The AsBinary function returns VARCHAR data type with binary collation.
It can cause problem for clients that treat that kind of data as
different from BLOB type.
So now AsBinary returns BLOB.

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.

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.

  Reverted fix for bug#18360

there was two problems about charsets in embedded server
1. mysys/charset.c - defined there default_charset_info variable is
modified by both server and client code (particularly when
--default-charset option is handled)
In embedded server we get two codelines modifying one variable.
I created separate default_client_charset_info for client code

2. mysql->charset and mysql->options.charset initialization isn't
properly done for embedded server - necessary calls added

              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.
