The task is to
(a) add a comment on indexes and
(b) increase the maximum length of column, table and the new index comments.

WL#5154 - Remove deprecated 4.1 features
The fix is the removal of the sql_log_update_basic
test, as this option is deprecated and removed,
and a minor change to the result file of
lc_time_names_basic as the error message has
changed.
There are 2 different share directories, one if builddir/share (with compiled errmsg.sys)
and another one is $sourcedir/share and contains some /charsets/*.xml files.
second one should be refered to as MYSQL_CHARSETSDIR and MYSQL_SHAREDIR $builddir/share
1. Now test use fake_relay_log primitive
2. Added RESET SLAVE to include/setup_fake_relay_log.inc for removing relay log info file
3. Added RESET SLAVE to include/cleanup_fake_relay_log.inc
4. Test moved to rpl suite as rpl_binlog_auto_inc_bug33029.test
5. Updated result file
--slave-load-tm
The MDL_SHARED lock was introduced for an object in 5.4, but the 'TABLE_LIST'
object was not initialized with the MDL_SHARED lock when applying event with
LOAD DATA INFILE into table. So the failure is caused when checking the
MDL_SHARED lock for the object.
To fix the problem, the 'TABLE_LIST' object was initialized with the MDL_SHARED
lock when applying event with LOAD DATA INFILE into table.
The test case for this bug relies on getting a ER_LOCK_WAIT_TIMEOUT
error. However with the introduction of MDL, the test would hang
forever since the metadata locks would not timeout.
MDL timeouts are now introduced in the scope of Bug#45225. This
patch changes the testcase for Bug#34604 to set the new server
variable "lock_wait_timeout" to one second which makes the test
generate the necessary timeout again.
This patch introduces timeouts for metadata locks.
The timeout is specified in seconds using the new dynamic system
variable "lock_wait_timeout" which has both GLOBAL and SESSION
scopes. Allowed values range from 1 to 31536000 seconds (= 1 year).
The default value is 1 year.
The new server parameter "lock-wait-timeout" can be used to set
the default value parameter upon server startup.
"lock_wait_timeout" applies to all statements that use metadata locks.
These include DML and DDL operations on tables, views, stored procedures
and stored functions. They also include LOCK TABLES, FLUSH TABLES WITH
READ LOCK and HANDLER statements.
The patch also changes thr_lock.c code (table data locks used by MyISAM
and other simplistic engines) to use the same system variable.
InnoDB row locks are unaffected.
One exception to the handling of the "lock_wait_timeout" variable
is delayed inserts. All delayed inserts are executed with a timeout
of 1 year regardless of the setting for the global variable. As the
connection issuing the delayed insert gets no notification of
delayed insert timeouts, we want to avoid unnecessary timeouts.
It's important to note that the timeout value is used for each lock
acquired and that one statement can take more than one lock.
A statement can therefore block for longer than the lock_wait_timeout
value before reporting a timeout error. When lock timeout occurs,
ER_LOCK_WAIT_TIMEOUT is reported.
Test case added to lock_multi.test.
We found that there are some tests that are not cleaning
up properly:
1. rpl_tmp_table_and_DDL
2. rpl_do_grant
3. rpl_sync
For #1 and #2 we found that the slave would not, for some
cases, replicate all the instructions the master processed
in the cleanup section. We fix these by deploying some
synchronization commands in the test cases so that slave
processes all clean up instructions.
As for #3, this is tracked as part of another bug
(BUG@50442).
Problem was that in mysql-trunk the ER() macro is now dependent on current_thd
and the innodb monitor thread has no binding to that thd object. This cause
the crash because of bad derefencing.
Solution was to add a new macro which take the thd as an argument (which the innodb
thread uses for the call).
(Updated according to reviewers comments, i.e. added ER_THD_OR_DEFAULT and
moved test to suite parts.)
As part of BUG@39934 fix, the public:
- THD::current_stmt_binlog_row_based
variable had been removed and replaced by a private variable:
- THD::current_stmt_binlog_format.
THD was refactored and some modifiers and accessors were
implemented for the new variable.
However, due to a bad merge, the
THD::current_stmt_binlog_row_based variable is back as a public
member of THD. This in itself is already potentially
harmful. What's even worse is that while merging some more
patches and resolving conflicts, the variable started being used
again, which is obviously wrong.
To fix this we:
1. remove the extraneous variable from sql_class.h
2. revert a bad merge for BUG#49132
3. merge BUG#49132 properly again (actually, making use of the
cset used to merge the original patch to mysql-pe).
