Valgrind warning happpens because of uninitialized null bytes.
In row_sel_push_cache_row_for_mysql() function we fill fetch cache
with necessary field values, row_sel_store_mysql_rec() is called
for this and leaves null bytes untouched.
Later row_sel_pop_cached_row_for_mysql() rewrites table record
buffer with uninited null bytes. We can see the problem from the
test case:
At 'SELECT...' we call row_sel_push...->row_sel_store...->row_sel_pop_cached...
chain which rewrites table->record[0] buffer with uninitialized null bytes.
When we call 'UPDATE...' statement, compare_record uses this buffer and
valgrind warning occurs.
The fix is to init null bytes with default values.

init null bytes with default values as they might be

might be copied into mysql record buffer that leads to
valgrind warnings on next use of the buffer.
Logging slow stored procedures caused the slow log to write
very large lock times. The lock times was a result of a
negative number being cast to an unsigned integer.
The reason the lock time appeard negative was because
one of the measurements points was reset after execution
causing it to change order with the start time of the
statement.
This bug is related to bug 47905 which in turn was
introduced because of a joint fix for 12480,12481,12482 and 11587.
The fix is to only reset the start_time before any statement
execution in a SP while not resetting start_utime or
utime_after_lock which are used for measuring the
performance of the SP. Start_time is used to set the
timestamp on the replication event which controlls how
the slave interprets time functions like NOW().

When using Unique Keys with nullable parts in RBR, the slave can
choose the wrong row to update. This happens because a table with
an unique key containing nullable parts cannot strictly guarantee
uniqueness. As stated in the manual, for all engines, a UNIQUE
index allows multiple NULL values for columns that can contain
NULL.
We fix this at the slave by extending the checks before assuming
that the row found through an unique index is is the correct
one. This means that when a record (R) is fetched from the storage
engine and a key that is not primary (K) is used, the server does
the following:
- If K is unique and has no nullable parts, it returns R;
- Otherwise, if any field in the before image that is part of K
is null do an index scan;
- If there is no NULL field in the BI part of K, then return R.
A side change: renamed the existing test case file and added a
test case covering the changes in this patch.

Some of the test cases reference to binlog position and
these position numbers are written into result explicitly.
It is difficult to maintain if log event format changes.
There are a couple of cases explicit position number appears,
we handle them in different ways
A. 'CHANGE MASTER ...' with MASTER_LOG_POS or/and RELAY_LOG_POS options
Use --replace_result to mask them.
B. 'SHOW BINLOG EVENT ...'
Replaced by show_binlog_events.inc or wait_for_binlog_event.inc.
show_binlog_events.inc file's function is enhanced by given
$binlog_file and $binlog_limit.
C. 'SHOW SLAVE STATUS', 'show_slave_status.inc' and 'show_slave_status2.inc'
For the test cases just care a few items in the result of 'SHOW SLAVE STATUS',
only the items related to each test case are showed.
'show_slave_status.inc' is rebuild, only the given items in $status_items
will be showed.
'check_slave_is_running.inc' and 'check_slave_no_error.inc'
and 'check_slave_param.inc' are auxiliary files helping
to show running status and error information easily.

message:
Followup to Bug#51920, fix binlog.binlog_killed
This is a followup to the fix of
Bug#51920 Innodb connections in row lock wait ignore KILL until lock wait
timeout
in that fix (rb://279) the behavior was changed to honor when a trx is
interrupted during lock wait, but the returned error code was still
"lock wait timeout" when it should be "interrupted".
This change fixes the non-deterministically failing test binlog.binlog_killed,
that failed like this:
binlog.binlog_killed 'stmt' [ fail ]
Test ended at 2010-05-12 11:39:08
CURRENT_TEST: binlog.binlog_killed
mysqltest: At line 208: query 'reap' failed with wrong errno 1205: 'Lock wait timeout exceeded; try restarting transaction', instead of 0...
Approved by: Sunny Bains (rb://344)
------------------------------------------------------------
This merge is non-trivial since it has to introduce the DB_INTERRUPTED
error code.
Also revert vasil.dimov@oracle.com-20100408165555-9rpjh24o0sa9ad5y
which adjusted the binlog.binlog_killed test to the new (wrong) behavior
This patch fixes two problems described as follows:
1 - If there is an on-going transaction and a temporary table is created or
dropped, any failed statement that follows the "create" or "drop commands"
triggers a rollback and by consequence the slave will go out sync because
the binary log will have a wrong sequence of events.
To fix the problem, we changed the expression that evaluates when the
cache should be flushed after either the rollback of a statment or
transaction.
2 - When a "CREATE TEMPORARY TABLE SELECT * FROM" was executed the
OPTION_KEEP_LOG was not set into the thd->options. For that reason, if
the transaction had updated only transactional engines and was rolled
back at the end (.e.g due to a deadlock) the changes were not written
to the binary log, including the creation of the temporary table.
To fix the problem, we have set the OPTION_KEEP_LOG into the thd->options
when a "CREATE TEMPORARY TABLE SELECT * FROM" is executed.
sql/log.cc:
Reorganized the code based on the following functions:
- bool ending_trans(const THD* thd, const bool all);
- bool trans_has_updated_non_trans_table(const THD* thd);
- bool trans_has_no_stmt_committed(const THD* thd, const bool all);
- bool stmt_has_updated_non_trans_table(const THD* thd);
sql/log.h:
Added functions to organize the code in log.cc.
sql/log_event.cc:
Removed the OPTION_KEEP_LOG since it must be used only when
creating and dropping temporary tables.
sql/log_event_old.cc:
Removed the OPTION_KEEP_LOG since it must be used only when
creating and dropping temporary tables.
sql/sql_parse.cc:
When a "CREATE TEMPORARY TABLE SELECT * FROM" was executed the
OPTION_KEEP_LOG was not set into the thd->options.
To fix the problem, we have set the OPTION_KEEP_LOG into the
thd->options when a "CREATE TEMPORARY TABLE SELECT * FROM"
is executed.
Post-fix: Updated a test case after the patch for BUG#50410,
because the patch makes ndb to run in the row format and as
such unsafe warning messages are not printed out.
The statistics after a sequence of inserts/deletes are updated asynchronously
in PBXT, causing unpredictable test results. Fix by running the test on a
fresh copy of the table with no deletes performed, to get stable results.
Also make InnoDB thinks that /*/ only starts a comment. (Bug #53644).
This fixes the bugs in the InnoDB Plugin.
ha_innodb.h: Use trx_query_string() instead of trx_query() when
available (MySQL 5.1.42 or later).
innobase_get_stmt(): New function, to retrieve the currently running
SQL statement.
struct trx_struct: Remove mysql_query_str. Use innobase_get_stmt() instead.
dict_strip_comments(): Add and observe the parameter sql_length. Treat
/*/ as the start of a comment.
dict_create_foreign_constraints(), row_table_add_foreign_constraints():
Add the parameter sql_length.
Also make InnoDB thinks that /*/ only starts a comment. (Bug #53644).
struct trx_struct: Add mysql_query_len.
ha_innodb.cc: Use trx_query_string() instead of trx_query() and
initialize trx->mysql_query_len.
INNOBASE_COPY_STMT(thd, trx): New macro, to initialize
trx->mysql_query_str and trx->mysql_query_len.
dict_strip_comments(): Add and observe the parameter sql_length. Treat
/*/ as the start of a comment.
dict_create_foreign_constraints(), row_table_add_foreign_constraints():
Add the parameter sql_length.
mysql-test/suite/binlog/r/binlog_unsafe.result:
Updated results (RAND() doesn't require statement based logging anymore for inserts)
mysql-test/t/information_schema_all_engines.test:
Ensure that InnoDB is used
storage/pbxt/bin/Makefile.am:
Fixed build failure on build hosts
(Patch from Kristian Nielsen)
storage/pbxt/bin/xtstat_xt.cc:
Added missing argument
storage/pbxt/src/datalog_xt.cc:
Fixed compiler warnings
storage/pbxt/src/ha_pbxt.cc:
Fixed compiler warnings
storage/pbxt/src/table_xt.cc:
Fixed compiler warnings
support-files/compiler_warnings.supp:
Added suppression of compiler warnings in Xtradb
(Failure can only happen for corrupted tables, but should be fixed properly at some point)
MTR sporadically reported that rpl_do_grant does not
clean up after itself.
We fix this by backporting BUG 50984 fix. This deploys
missing synchronization between master and slave.
Additionally, it also fixes the check_testcase for
rpl_tmp_table_and_DDL.
- INSERT with RAND() doesn't require row based logging again
- Some bugs fixed in opt_range() where we table->key_read was wrongly used
.bzrignore:
Ignore new xtstat binary
mysql-test/r/index_merge_myisam.result:
Update results (old result was wrong)
mysql-test/suite/binlog/r/binlog_stm_binlog.result:
Added drop table first
mysql-test/suite/binlog/r/binlog_stm_unsafe_warning.result:
Added test for when RAND() requires row based logging
mysql-test/suite/binlog/t/binlog_stm_binlog.test:
Added drop table first
mysql-test/suite/binlog/t/binlog_stm_unsafe_warning.test:
Added test for when RAND() requires row based logging
scripts/make_binary_distribution.sh:
Removed type from last commit
sql/item_create.cc:
Don't require row based logging when using RAND() with INSERT
sql/opt_range.cc:
Revert wrong patch from Oracle:
- As QUICK_RANGE_SELECT uses it's own 'file' handler to the tables, one can't use 'table->key_read' as a flag to detect if index only read (keyread) is used or not
- Don't set keyread if keyread is already enabled
- Don't disable key read, if we didn't enable it ourselves
- Simplify code (and ensure that we do proper cleanup of index only read)
sql/opt_range.h:
Added flags to detect if the range optimizer enabled index only read (key read) or not
sql/opt_sum.cc:
Use our more optimized macros
sql/sql_lex.h:
Added 'readable' function to check if we are in a sub query function or not (not normal query or sub query in FROM clause)
sql/sql_select.cc:
Use our more optimized keyread macros
Added ASSERTS early
Simplify code on eliminate_item_equal()
Fixed that substitute_for_best_equal_field() doesn't core dump in case of out of memory conditions.
Removed not needed test for 'field->maybe_null()'
Replaced master_unit()->item with is_subquery_function() (More readable)
sql/sql_update.cc:
Use our more optimized keyread macros
sql/table.cc:
Use our more optimized keyread macros
sql/table.h:
Use separate functions to enable/disable Index only reads
- Safer, more readable, better logging and faster.
Problem: The rpl_ndb did not set binlog_format explicitly. Since
the default is binlog_format=statement, it means that the suite
ran with that. ndb does not support binlog_format=statement,
and many tests were skipped because they sourced
include/have_binlog_format_row_or_mixed.inc
Fix: set binlog_format=row explicitly in the configuration file
for the rpl_ndb suite.
Makefile.am:
Removed duplicate run of rpl_ndb suite with binlog_format=row.
Now that rpl_ndb is run with binlog_format=row by default, this
run that explicitly changes to binlog_format=row is not needed,
because it is covered by the following run.
mysql-test/suite/rpl_ndb/my.cnf:
cluster only supports binlog_format=row.
mysql-test/suite/rpl_ndb/r/rpl_ndb_stm_innodb.result:
updated result file
mysql-test/suite/rpl_ndb/t/rpl_ndb_stm_innodb.test:
This test is supposed to use binlog_format=STATEMENT on
master. It uses innodb on master, so statement format is
supported.
commit e759bc64eb5c5eed4f75677ad67246797d486460
Author: Ryan Mack
Date: 3 days ago
Bugfix for 53290, fast unique index creation fails on duplicate null values
Summary:
Bug in the fast index creation code incorrectly considers null
values to be duplicates during block merging. Innodb policy is that
multiple null values are allowed in a unique index. Null duplicates
were correctly ignored while sorting individual blocks and with slow
index creation.
Test Plan:
mtr, including new test, load dbs using deferred index creation
