6a71b067b0 Fixed bug #29938.
mysqldump --skip-events --all-databases dumped data of the mysqld.event table,
and during the restoration from this dump events were created in spite
of the --skip-events option.

The mysqldump client has been modified to ignore mysql.event table data
in case of --skip-events options.


client/mysqldump.c:
  Fixed bug #29938.
  The dump_table function has been modified to skip dumping of
  the mysql.event table data in case of the --skip-event mysqldump
  client option.
mysql-test/t/mysqldump.test:
  Updated test case for bug #29938.

f0d4beee79 Bug #30234: Unexpected behavior using DELETE with AS and USING
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.

ff149b713c Fixed bug #30126.
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

  The init_dumping_tables function has been modified to output semicolon
  outside of commentaries.

41a2f1c8de Bug#28779 (mysql_query() allows execution of statements with unbalanced
comments)

This change set is for 5.1 (manually merged)

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.

  Unbalanced comments are a syntax error.

bb986a24e7 Bug #30164: Using client side macro inside server side comments generates broken queries
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).

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

26aadd2175 Bug#21975 Grant and revoke statements are non-transactional
Bug#21422 GRANT/REVOKE possible inside stored function, probably in a trigger
Bug#17244 GRANT gives strange error message when used in a stored function

GRANT/REVOKE statements are non-transactional (no explicit transaction
boundaries) in nature and hence are forbidden inside stored functions and
triggers, but they weren't being effectively forbidden. Furthermore, the
absence of implict commits makes changes made by GRANT/REVOKE statements to
not be rolled back.

The implemented fix is to issue a implicit commit with every GRANT/REVOKE
statement, effectively prohibiting these statements in stored functions
and triggers. The implicit commit also fixes the replication bug, and looks
like being in concert with the behavior of DDL and administrative statements.

Since this is a incompatible change, the following sentence should be
added to the Manual in the very end of the 3rd paragraph, subclause
13.4.3 "Statements That Cause an Implicit Commit": "Beginning with
MySQL 5.0.??, the GRANT and REVOKE statements cause an implicit commit."

  transactional statements.

1bae3c20a8 Bug #30393: Test "group_by" fails with a difference in "row count"
and strategy (explain)
  
The fix for WL3527 adds tests that test if the index usage hints
combinations don't cause syntax errors.
The EXPLAIN for one of these tests can be affected by the size of the
rowid on the disk (affected by the presence of large file support). 
Fixed to avoid the platform dependent test result by removing the 
irrelevant columns from the EXPLAIN result.

e0e44ad66e Bug#30625 (Performance, reduce depth for expressions)
This is a performance bug, affecting in particular the bison generated code
for the parser.

Prior to this fix, the grammar used a long chain of reduces to parse an
expression, like:
  bit_expr -> bit_term
  bit_term -> bit_factor
  bit_factor -> value_expr
  value_expr -> term
  term -> factor
etc

This chain of reduces cause the internal state automaton in the generated
parser to execute more state transitions and more reduces, so that the
generated MySQLParse() function would spend a lot of time looping to execute
all the grammar reductions.

With this patch, the grammar has been reorganized so that rules are more
"flat", limiting the depth of reduces needed to parse <expr>.

Tests have been written to enforce that relative priorities and properties
of operators have not changed while changing the grammar.

See the bug report for performance data.

22440b5387 Bug #30596 GROUP BY optimization gives wrong result order
The optimization that uses a unique index to remove GROUP BY did not 
ensure that the index was actually used, thus violating the ORDER BY
that is implied by GROUP BY.
Fixed by replacing GROUP BY with ORDER BY if the GROUP BY clause contains
a unique index over non-nullable field(s). In case GROUP BY ... ORDER BY 
null is used, GROUP BY is simply removed.

  Bug#30596: Test case for InnoDB
  Here, as opposed to for MyISAM, row lookup is done using index 
  whenever the index covers the group list.
mysql-test/r/distinct.result:
  Bug#30596: Changed test case. 
  Prior to Bug#16458, These queries use temp table and filesort. The
  bug was that they used a temp table. However, that patch removed
  filesort also, in which case we can no longer gurantee correct ordering.
mysql-test/r/group_by.result:
  Bug#30596: Correct result
  The test case for IGNORE INDEX FOR GROUP BY gets degraded performance 
  (unneccesary filesort). This is due to Bug#30665, which will be fixed separately.

310afbd4a9 Bug #30377: EXPLAIN loses last_query_cost when used with UNION
Currently the Last_query_cost session status variable shows
only the cost of a single flat subselect. For complex queries
(with subselects or unions etc) Last_query_cost is not valid
as it was showing the cost for the last optimized subselect.
Fixed by reseting to zero Last_query_cost when the complete
cost of the query cannot be determined.
Last_query_cost will be non-zero only for single flat queries.
