Added a case for bug #4976 when one of the inner tables is empty.
select.result, join.result:
Reversed the previous change of the erronious fix for bug #4976.
sql_select.cc:
The previous fix for bug 4976 was reversed as it
erroniously converted an outer join into an innner join
when on_expression does not refer to outer tables.
This is not valid if inner tables return an empty set.
Setting dependency on outer tables was added for the above cases.
To fix the crash in the test case of bug #4976
a guard was added that blocks running the crashing code for
nested outer joins.

mysql-test/t/join_nested.test:
Added a case for bug #4976 when one of the inner tables is empty.
The crash is eliminated but still it is weird/inefficent that ROR-intersection is used when performing updates in empty table.

mysql-test/r/join_nested.result:
Added a test case for bug #4922.
...and added new test file, sp-threads, for multiple connection tests
(apart from the security tests that are in sp-security).
sql/sp.cc:
When removing an SP, invalidate the caches even if the
removing thread doesn't have one.
The description is not entirerly correct. The issue was follow-up errors
where the first error is not caught - in which case it's often a system
error with errcode < 1000 (which are mapped by default to 'HY000'). In this
case the error state is different from what was assumed in the execution
loop.
mysql-test/r/sp.result:
New test case for BUG#4902.
mysql-test/t/sp.test:
New test case for BUG#4902.
sql/sp_head.cc:
Don't test the net.report_error flag in the execution loop. (Don't know
why this was done in the first place, as it seems to serve no purpose.)
and tried to do it properly this time, digging out all show commands that
need the multi results flag set.
mysql-test/r/sp.result:
New test case for BUG#4902, with lots of other show commands as well.
mysql-test/t/sp.test:
New test case for BUG#4902, with lots of other show commands as well.
sql/sp_head.cc:
The check for possible multiple result commands was becomming unwieldly,
so we moved it to a separate function, and added loads of new command codes
to the test.
sql/sp_head.h:
The check for possible multiple result commands was becomming unwieldly,
so we moved it to a separate function.
sql/sql_yacc.yy:
The check for possible multiple result commands was becomming unwieldly,
so we moved it to a separate function.
- client side part is simple and may be considered stable
- server side part now just joggles with THD state to save execution
state and has no additional locking wisdom.
Lot's of it are to be rewritten.
include/mysql.h:
Cursor patch to push into the main tree, client library part (considered
stable):
- new statement attribute STMT_ATTR_CURSOR_TYPE
- MYSQL_STMT::flags to store statement cursor type
- MYSQL_STMT::server_status to store server status (i. e. if the server
was able to open a cursor for this query).
include/mysql_com.h:
Cursor patch to push into the main tree, client library part (considered
stable):
- new COMmand, COM_FETCH, to fetch K rows from read-only cursor.
By design should support scrollable cursors as well.
- a few new server statuses:
SERVER_STATUS_CURSOR_EXISTS is sent by server in reply to COM_EXECUTE,
when cursor was successfully opened for this query
SERVER_STATUS_LAST_ROW_SENT is sent along with the last row to prevent one
more round trip just for finding out that all rows were fetched from
this cursor (this is server mem savier also).
- and finally, all possible values of STMT_ATTR_CURSOR_TYPE,
while now we support only CURSORT_TYPE_NO_CURSOR and
CURSOR_TYPE_READ_ONLY
libmysql/libmysql.c:
Cursor patch to push into the main tree, client library part (considered
stable):
- simple additions to mysql_stmt_fetch implementation to read data
from an opened cursor: we can read up to iteration count rows per
one request; read rows are buffered in the same way as rows of
mysql_stmt_store_result.
- now send stmt->flags to server to let him now if we wish to have
a cursor for this statement.
- support for setting/getting statement cursor type.
libmysqld/examples/Makefile.am:
Testing cursors was originally implemented in C++. Now when these tests
go into client_test, it's time to convert it to C++ as well.
libmysqld/lib_sql.cc:
- cleanup: send_fields flags are now named.
sql/ha_innodb.cc:
- cleanup: send_fields flags are now named.
sql/mysql_priv.h:
- cursors support: declaration for server-side handler of COM_FETCH
sql/protocol.cc:
- cleanup: send_fields flags are now named.
- we can't anymore assert that field_types[field_pos] is sensible:
if we have COM_EXCUTE(stmt1), COM_EXECUTE(stmt2), COM_FETCH(stmt1)
field_types[field_pos] will point to fields of stmt2.
sql/protocol.h:

sql/sql_help.cc:
- cleanup: send_fields flags are now named.
sql/sql_parse.cc:
Server side support for cursors:
- handle COM_FETCH
- enforce assumption that whenever we free thd->free_list,
we reset it to zero. This way it's much easier to handle free_list
in prepared statements implementation.
sql/sql_prepare.cc:
Server side support for cursors:
- implementation of mysql_stmt_fetch (fetch some rows from open cursor).
- management of cursors memory is quite tricky now.
- execute_stmt can't be reused anymore in mysql_stmt_execute and
mysql_sql_stmt_execute
sql/sql_repl.cc:
- cleanup: send_fields flags are now named.
sql/sql_select.cc:
Server side support for cursors:
- implementation of Cursor::open, Cursor::fetch (buggy when it comes to
non-equi joins), cursor cleanups.
- -4 -3 -0 constants indicating return value of sub_select and end_send are
to be renamed to something more readable:
it turned out to be not so simple, so it should come with the other patch.
sql/sql_select.h:
Server side support for cursors:
- declaration of Cursor class.
- JOIN::fetch_limit contains runtime value of rows fetched via cursor.
sql/sql_show.cc:
- cleanup: send_fields flags are now named.
sql/sql_table.cc:
- cleanup: send_fields flags are now named.
sql/sql_union.cc:
- if there was a cursor, don't cleanup unit: we'll need it to fetch
the rest of the rows.
tests/Makefile.am:
Now client_test is in C++.
tests/client_test.cc:
A few elementary tests for cursors.
BitKeeper/etc/ignore:
Added libmysqld/examples/client_test.cc to the ignore list
Added a simple optimizer that shortcuts jumps and skip unused instructions.

sql/sql_yacc.yy:
Don't allow drop function/procedure from within another function/procedure.
at least partially. It doesn't crash or give packets out of order
any more, but it's unclear why it doesn't actually return anything
from within an SP. This should be investigated at some point, but
for the moment this will have to do. (It is a rather obscure feature... :)

sql/sql_yacc.yy:

(including one which may explain autobuild's failure of yesterday)
client/mysqlbinlog.cc:
- In mysqlbinlog, we should not reset the Format event when we see Rotate. If a binlog started with a Format event, it is not going to switch later to 4.0 format.
I had already did the same fix in Rotate_log_event::exec_event() in replication.
- Fix for a merge bug.
sql/log_event.cc:
An event with an uninited catalog (read from a 4.x server) is not the same as an event with a NULL catalog
(5.0 server which did not specify catalog), the difference is that they are not in the same format;
so I introduce a way to know if the catalog has been inited or not. This fixes a rpl_trunc_binlog failure
I had.
When we leave Load_log_event::exec_event(), we must reset thd->catalog to 0, like we already do
in Query_log_event::exec_event(). This fixes a Valgrind error which popped in rpl_charset (which may
be what caused autobuild to crash yesterday).
And a fix for event's parsing (the position was always computed right because start_dup==end is always true
and will until we add new string members to Query_log_event.
sql/log_event.h:
catalog_len changed from uint to int to allow -1, which means "not inited"
(I preferred to do it like this rather than create a new bool var Query_log_event::catalog_inited
like we have in Query_log_event::sql_mode_inited; that's because catalog will not use the whole range of int,
so it's allowed to pick -1 as a special value and have only one var.
