we will allow multi-comments pretty much anywhere within SQL-statements,
but client-specific commands (help, use, print, ...) must be the first token

The problem is that the author used the wrong function to send a warning to the 
user about truncation of data.  push_warning() takes a constant string and 
push_warning_printf() takes a format and variable arguments to fill it.

Since the string we were complaining about contains percent characters, the 
printf() code interprets the "%Y" et c. that the user sends.  That's wrong, and
often causes a crash, especially if the date mentions seconds, "%s".

A alternate fix would be to use  push_warning_printf(..., "%s", warn_buff) .

  The intention with the original code was to show that MySQL treats the first
  given unique key as a primary key. Clients can use the marked primary key as a
  real primary key to validate row changes in case of conflicting updates.  The
  ODBC driver (and other drivers) may also use this fact to optimize/check
  updates and handle conflicts.  The marked key also shows what some engines, like InnoDB or NDB,
  will use as it's internal primary key.
  
  For checking if someone has declared a true PRIMARY KEY, one should use 'SHOW CREATE TABLE'

When using a parameter bind MYSQL_TYPE_DATE in a prepared statement,
the time part of the MYSQL_TIME buffer was written to zero in
mysql_stmt_execute(). The param_store_date() function in libmysql.c
worked directly on the provided buffer.
Changed to use a copy of the buffer.

'SELECT DISTINCT a,b FROM t1' should not use temp table if there is unique 
index (or primary key) on a.
There are a number of other similar cases that can be calculated without the
use of a temp table : multi-part unique indexes, primary keys or using GROUP BY 
instead of DISTINCT.
When a GROUP BY/DISTINCT clause contains all key parts of a unique
index, then it is guaranteed that the fields of the clause will be
unique, therefore we can optimize away GROUP BY/DISTINCT altogether.
This optimization has two effects:
* there is no need to create a temporary table to compute the
   GROUP/DISTINCT operation (or the temporary table will be smaller if only GROUP 
   is removed and DISTINCT stays or if DISTINCT is removed and GROUP BY stays)
* this causes the statement in effect to become updatable in Connector/Java
because the result set columns will be direct reference to the primary key of 
the table (instead to the temporary table that it currently references). 

Implemented a check that will optimize away GROUP BY/DISTINCT for queries like 
the above.
Currently it will work only for single non-constant table in the FROM clause.

  An UNIQUE KEY consisting of NOT NULL columns
  was displayed as PRIMARY KEY in "DESC t1".
  According to the code, that was intentional

  was made to remove this code

This was another manifestation of the problems fixed in the
patch for bug 16674.
Wrong calculation of length of the search prefix in the pattern
string led here to a wrong result set for a query in 4.1. 
The bug could be demonstrated for any multi-byte character set. 


mysql-test/r/ctype_utf8.result:

mysql-test/t/ctype_utf8.test:
  Added a test case for bug #18359.

Server crashed in some cases when a query required a MIN/MAX
agrregation for a 'ucs2' field. 
In these cases  the aggregation caused calls of the function
update_tmptable_sum_func that indirectly invoked 
the method Item_sum_hybrid::min_max_update_str_field() 
containing a call to strip_sp for a ucs2 character set.
The latter led directly to the crash as it used my_isspace
undefined for the ucs2 character set.
Actually the call of strip_sp is not needed at all in this
situation and has been removed by the fix.
