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.

- force test_if_skip_sort_order to go backwards over the key even
when the number of keyparts used is the same as the number of
keyparts equal to a constant. (because of the primary key
suffix).
- 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).

If MYSQL_TCP_PORT defaulted in configure (factory default 3306
at the time of this writing), set MYSQL_TCP_PORT to factory
default, then clear factory default after. That way, we lose no
information, and we can distinguish between "defaulted" and the
pathological case "builder specifically configured a port that
coincides with factory default." This can in theory happen if
builder configures and builds several servers from a script
(--with-tcp-port=3306, --with-tcp-port=3316, --with-tcp-port=3326).
Not all that probable, but much preferable to having more "magic"
happen in the server when we can solve this without any guesswork.

DELETE query against memory table with btree index may remove
not all matching rows. This happens only when DELETE uses
index read method to find matching rows. E.g. for queries
like DELETE FROM t1 WHERE a=1.
Fixed by reverting fix for BUG9719 and applying proper solution.
heap/hp_delete.c:
Reverted fix for BUG9719 as it makes queries like
DELETE FROM t1 WHERE a=1 to remove not all matching
rows (assuming this is memory table and there is btree
key over `a`).
This happens because we calculate info->lastkey_len in
heap_rkey(). When we enter heap_rnext(), info->lastkey_len
is 0 (set by hp_rb_delete_key()). We need to preserve
info->lastkey_len in this situation, otherwise
tree_search_key() will always return smallest value in
a tree.
heap/hp_rfirst.c:
If we're performing index_first on a table that was taken from
table cache, info->lastkey_len is initialized to previous query.
Thus we set info->lastkey_len to proper value for subsequent
heap_rnext() calls.
This is needed for DELETE queries only, otherwise this variable is
not used.
Note that the same workaround may be needed for heap_rlast(), but
for now heap_rlast() is never used for DELETE queries.
heap/hp_rnext.c:
An optimization for DELETE queries that use index_first()/index_next().
Use faster tree_search_edge() instead of tree_search_key().

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.

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.

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.
client/mysqldump.c:
Fixed bug #30126.
The init_dumping_tables function has been modified to output semicolon
outside of commentaries.
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.

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.
