Removed the flag that disables innodb on slave in the default
configuration of replication tests. That made the explicit
--innodb flag in -slave.opt files redundant, so lots of -slave.opt
files could be removed. Also, -master.opt files containing reduntant
--innodb flag were removed (those were redundant even without
changing the default). Removing .opt files is good because .opt
files cause server restarts and make tests less readable.
Also fixed a bug where rpl_innodb_mixed_ddl unintentionally
used myisam on slave.
Problem: In the mysqltest language, it was not possible to set the current
connection from a variable, and it was not possible to read the current
connection.
Fix: Allow setting the connection from a variable, like:
connection $variable;
and introduce the mysqltest language variable $CURRENT_CONNECTION, which
holds the name of the current connection.
Debug builds of MySQL 5.1, 6.0 with Sun Studio 12 broke because of
use of gcc specific feature.
The fix is to replace __FUNCTION__ with the corresponding character string
Problem 1: not_embedded_server runs SELECT FROM I_S.PROCESSLIST near the beginning.
check_testcase executes a query to the server before that. There is a race here,
because there is no guarantee that the thread executing check_testcase's query is
finished.
Problem 2: The SELECT FROM I_S.PROCESSLIST doens't seem very useful in the test.
It's at least misplaced.
Fix to both problems: Comment out SELECT FROM I_S.PROCESSLIST.
Problem: during a refactoring of mtr, a pattern for suppressing a warning from lowercase_table3 was lost.
Fix: re-introduce the suppression.
Problem 2: suppression was misspelt as supression. Fixed by adding a p.
derived table cause crash
When a multi-UPDATE command fails to lock some table, and
subsequently succeeds, the tables need to be reopened if
they were altered. But the reopening procedure failed for
derived tables.
Extra cleanup has been added.
upgrade from <=5.0.46 to >=5.0.48
Problem: 'check table .. for upgrade' doesn't detect
incompatible collation changes made in 5.0.48.
Fix: check for incompatible collation changes.
The failure was caused by executing a CREATE-SELECT statement that creates a
table in another database than the current one. In row-based logging, the
CREATE statement was written to the binary log without the database, hence
creating the table in the wrong database, causing the following inserts to
fail since the table didn't exist in the given database.
Fixed the bug by adding a parameter to store_create_info() that will make
the function print the database name before the table name and used that
in the calls that write the CREATE statement to the binary log. The database
name is only printed if it is different than the currently selected database.
The output of SHOW CREATE TABLE has not changed and is still printed without
the database name.
InnoDB Plugin locks table
This is a pre fix update that does the change to the handler api.
This is done since there are already changes in this version,
so the real fix does not need to change the api.
``FLUSH TABLES WITH READ LOCK''
Concurrent execution of 1) multitable update with a
NATURAL/USING join and 2) a such query as "FLUSH TABLES
WITH READ LOCK" or "ALTER TABLE" of updating table led
to a server crash.
The mysql_multi_update_prepare() function call is optimized
to lock updating tables only, so it postpones locking to
the last, and if locking fails, it does cleanup of modified
syntax structures and repeats a query analysis. However,
that cleanup procedure was incomplete for NATURAL/USING join
syntax data: 1) some Field_item items pointed into freed
table structures, and 2) the TABLE_LIST::join_columns fields
was not reset.
Major change:
short-living Field *Natural_join_column::table_field has
been replaced with long-living Item*.
ha_statistic_increment for rpl_temporary
Problem: in some cases master send a special event to reconnecting
slave to keep slave's temporary tables (see #17284) and they still
have references to the "old" SQL slave thread and use them to access
thread's data.
Fix: set temporary tables thread references to the actual SQL slave
thread in such cases.
