- Move the code to generate test report to the test tool(in this
case mysqltest) where the best control of what failed is
- Simplify the code in mysql-test-run.pl
- mysqltest will now find what diff to use in a best effort attempt
using "diff -u", "diff -c" and finally dumping the two files verbatim
in the report.
Problem: thd->thread_specific_used flag is not set executing a statement
containig connection_id() function using PS protocol, that leads to
improper binlog event creation.
Fix: set the flag in the Item_func_connection_id::fix_fields().
restores from mysqlbinlog out
Problem: using "mysqlbinlog | mysql" for recoveries the connection_id()
result may differ from what was used when issuing the statement.
Fix: if there is a connection_id() in a statement, write to binlog
SET pseudo_thread_id= XXX; before it and use the value later on.
which does not work. Removing these attempted privileges makes
this identical to option 5 so remove it completely. The spirit
of the program appears to be aimed at database privileges, so do
not add another option for granting global privileges as it may
be unexpected. Fixes bug#14618 (same as previous patch, this
time applied to -maint tree).
mysqld hasn't been built on AIX with ndb-everything in quite a while.
this allowed a variety of changes to be added that broke the AIX build
for both the GNU and IBM compilers (but the IBM suite in particular).
Changeset lets build to complete on AIX 5.2 for users of the GNU and
the IBM suite both. Tudo bem?
- Don't call mysql_select() several times for the select that enumerates
a temporary table with the results of the UNION. Making this call for
every subquery execution caused O(#enumerated-rows-in-the-outer-query)
memory allocations.
- Instead, call join->reinit() and join->exec(), and
= disable constant table detection for such joins,
= provide special handling for table-less constant subqueries.
SELECT statement itself returns empty.
As a result of this bug 'SELECT AGGREGATE_FUNCTION(fld) ... GROUP BY'
can return one row instead of an empty result set.
When GROUP BY only has fields of constant tables
(with a single row), the optimizer deletes the group_list.
After that we lose the information about whether we had an
GROUP BY statement. Though it's important
as SELECT min(x) from empty_table; and
SELECT min(x) from empty_table GROUP BY y; have to return
different results - the first query should return one row,
second - an empty result set.
So here we add the 'group_optimized_away' flag to remember this case
when GROUP BY exists in the query and is removed
by the optimizer, and check this flag in end_send_group()
to "my_config.h". Not to pollute the top directory, and to get more control
over what is included. Made the include path for "libedit" pick up its own
"config.h" first.
Backport of correction for Mac OS X build problem, global variable not
initiated is "common" and can't be used in shared libraries, unless
special flags are used (bug#26218)
