The optimizer sets index traversal in reverse order only if there are 
 used key parts that are not compared to a constant.
However using the primary key as an ORDER BY suffix rendered the check
incomplete : going in reverse order must still be used even if 
all the parts of the secondary key are compared to a constant.

Fixed by relaxing the check and set reverse traversal even when all
the secondary index keyparts are compared to a const.
Also account for the case when all the primary keys are compared to a
constant.

- The bug was caused by COUNT(DISTINCT ...) code using Unique object in 
  a way that assumed that BIT(N) column occupies a contiguous space in
  temp_table->record[0] buffer. 
- The fix is to make COUNT(DISTINCT ...) code instruct create_tmp_table to
  create temporary table with column of type BIGINT, not BIT(N).

DELETE FROM ... USING ... statements with the following type of 
ambiguous aliasing gave unexpected results:
DELETE FROM t1 AS alias USING t1, t2 AS alias WHERE t1.a = alias.a;
This query would leave table t1 intact but delete rows from t2.
Fixed by changing DELETE FROM ... USING syntax so that only alias 
references (as opposed to alias declarations) may be used in FROM.

Invaldating a subset of a sufficiently large query cache can take a long time.
During this time the server is efficiently frozen and no other operation can
be executed. This patch addresses this problem by setting a time limit on
how long time a dictionary access request can take before giving up on the 
attempt. This patch does not work for query cache invalidations issued by
DROP, ALTER or RENAME TABLE operations.


sql/sql_cache.cc:
  Changed mutex locking to a timed spinn lock. If access to query cache dictionary
  takes "a long time" (currently more than 0.1 seconds) the system fall backs on
  ordinary statement execution.

When dumping database from a 4.x server, the mysqldump client
inserted a delimiter sign inside special commentaries of the form:
  /*!... CREATE DATABASE IF NOT EXISTS ... ;*/
During restoration that dump file was splitten by delimiter signs on
the client side, and the rest of some commentary strings was prepended
to following statements.

The 4x_server_emul test case option has been added for use with the
DBUG_EXECUTE_IF debugging macro. This option affects debug server
builds only to emulate particular behavior of a 4.x server for
the mysqldump client testing. Non-debugging builds are not affected.

sql/sql_parse.cc:
  Fixed bug #30126.
  The mysqldump client uses the "SHOW CREATE DATABASE" query to
  obtain the "CREATE DATABASE" statement from that database.
  The 4.x server doesn't recognise that query, and mysqldump
  forms the "CREATE DATABASE" statement from scratch.
  That statement was formed incorrectly.
  
  To enforce the mysqldump client to create that statement from
  scratch, debugging code has been added to the mysql_execute_command
  function: in tcase of the --loose-debug=d,4x_server_emul option,
  the server returns parse error to client to emulate old behaviour.
  
  The 4x_server_emul test case option has been added for use with the
  DBUG_EXECUTE_IF debugging macro. This option affects debug server
  builds only to emulate particular behavior of a 4.x server for
  the mysqldump client testing. Non-debugging builds are not affected.

The problem is that a SELECT on one thread is blocked by INSERT ... ON
DUPLICATE KEY UPDATE on another thread even when low_priority_updates is
activated.

The solution is to possibly downgrade the lock type to the setting of
low_priority_updates if the INSERT cannot be concurrent.


sql/sql_insert.cc:
  Possibly downgrade lock type to the the setting of low_priority_updates if

Use double quotes instead of single ones which make the test fail on Windows. This is for bug #30164.


mysql-test/t/mysql.test:
  Use double quotes instead of single ones which make the test fail on Windows.

  
Problem:
  
In cases when a client-side macro appears inside a server-side comment, the add_line() function in mysql.cc discarded all characters until the next delimiter to remove macro arguments from the query string. This resulted in broken queries being sent to the server when the next delimiter character appeared past the comment's boundaries, because the comment closing sequence ('*/') was discarded.
  
Fix:
  
If a client-side macro appears inside a server-side comment, discard all characters in the comment after the macro (that is, until the end of the comment rather than the next delimiter).
This is a minimal fix to allow only simple cases used by the mysqlbinlog utility. Limitations that are worth documenting:
  
- Nested server-side and/or client-side comments are not supported by mysql.cc
- Using client-side macros in multi-line server-side comments is not supported
- All characters after a client-side macro in a server-side comment will be omitted from the query string (and thus, will not be sent to server).


client/mysql.cc:
  If a client-side macro appears inside a server-side comment, discard all characters in the comment after the macro.

comments)

Before this fix, the server would accept queries that contained comments,
even when the comments were not properly closed with a '*' '/' marker.

For example,
  select 1 /* + 2 <EOF>
would be accepted as
  select 1 /* + 2 */ <EOF>
and executed as
  select 1

With this fix, the server now rejects queries with unclosed comments
as syntax errors.
Both regular comments ('/' '*') and special comments ('/' '*' '!') must be
closed with '*' '/' to be parsed correctly.


mysql-test/r/comments.result:
  Unbalanced comments are a syntax error.
