bugfix: fix @@wait_timeout to work with socket timeouts (vs. alarm thread)
Bug#49836 reports that the geometry type does not work
with WL#5151 applied.
The GEOMETRY type inherits the blob comparison function,
which read the pack length from the metadata. The GEOMETRY
type does not fill in the metadata with anything sensible,
so it is always zero, meaning that the pack length for the
source type is considered zero, rendering it always "smaller"
than the target type which has pack length 4 (without pointer).
This patch fixes the problem by defining
Field_geom::pack_length_from_metadata() to always use the
same as Field_geom::row_pack_length().
when replicating
The function create_virtual_tmp_table does not
set db_low_byte_first in the same way as
create_tmp_table does, causing copying from
the virtual table to a real table to get strange
values for SET types on big-endian machines.
mysql-test/extra/rpl_tests/type_conversions.test:
Adding tests for converting between different-sized sets.
sql/sql_select.cc:
Settng dh_low_byte_first for tables created
with create_virtual_tmp_table.
'LOAD DATA CONCURRENT [LOCAL] INFILE ...' statment only is binlogged as
'LOAD DATA [LOCAL] INFILE ...' in SBR and MBR. As a result, if replication is on,
queries on slaves will be blocked by the replication SQL thread.
This patch write code to write 'CONCURRENT' into the log event if 'CONCURRENT' option
is in the original statement in SBR and MBR.
Problem: The test was written before BUG#45827 was fixed.
The test contained code that assumed the wrong behavior,
pre-BUG#45827. Then, the fix for BUG#45827 was merged
from 5.1-rep+2 to 5.1-rep+3. Since the test case assumed
the wrong behavior, it failed. This should have been fixed
by making the test assume the correct behavior, but was
fixed by updating the result file to assert failure.
Fix 1: fix the test to assume correct behavior
(post-BUG#45827), update result file.
Fix 2: make test fail with 'die' instead of 'exit' when
wrong behavior is detected. Thus, the test cannot be
silenced with a wrong result file in case the behavior
will change again.
mysql-test/extra/rpl_tests/create_recursive_construct.inc:
Replaced 'exit' by 'die' to avoid similar
mysql-test/suite/binlog/r/binlog_unsafe.result:
Updated result file.
mysql-test/suite/binlog/t/binlog_unsafe.test:
Since BUG#45827 is now fixed, we need to update the test case
in two places where it expects the wrong result because of
BUG#45827.
Row-based replication requires the types of columns on the
master and slave to be approximately the same (some safe
conversions between strings are allowed), but does not
allow safe conversions between fields of similar types such
as TINYINT and INT.
This patch implement type conversions between similar fields
on the master and slave.
The conversions are controlled using a new variable
SLAVE_TYPE_CONVERSIONS of type SET('ALL_LOSSY','ALL_NON_LOSSY').
Non-lossy conversions are any conversions that do not run the
risk of losing any information, while lossy conversions can
potentially truncate the value. The column definitions are
checked to decide if the conversion is acceptable.
If neither conversion is enabled, it is required that the
definitions of the columns are identical on master and slave.
Conversion is done by creating an internal conversion table,
unpacking the master data into it, and then copy the data to
the real table on the slave.

escaped field names
When in mixed or statement mode, the master logs LOAD DATA
queries by resorting to an Execute_load_query_log_event. This
event does not contain the original query, but a rewritten
version of it, which includes the table field names. However, the
rewrite does not escape the field names. If these names match a
reserved keyword, then the slave will stop with a syntax error
when executing the event.
We fix this by escaping the fields names as it happens already
for the table name.

message:
Bug#989: If DROP TABLE while there's an active transaction, wrong binlog order
WL#4284: Transactional DDL locking
Currently the MySQL server does not keep metadata locks on
schema objects for the duration of a transaction, thus failing
to guarantee the integrity of the schema objects being used
during the transaction and to protect then from concurrent
DDL operations. This also poses a problem for replication as
a DDL operation might be replicated even thought there are
active transactions using the object being modified.
The solution is to defer the release of metadata locks until
a active transaction is either committed or rolled back. This
prevents other statements from modifying the table for the
entire duration of the transaction. This provides commitment
ordering for guaranteeing serializability across multiple
transactions.
- Incompatible change:
If MySQL's metadata locking system encounters a lock conflict,
the usual schema is to use the try and back-off technique to
avoid deadlocks -- this schema consists in releasing all locks
and trying to acquire them all in one go.
But in a transactional context this algorithm can't be utilized
as its not possible to release locks acquired during the course
of the transaction without breaking the transaction commitments.
To avoid deadlocks in this case, the ER_LOCK_DEADLOCK will be
returned if a lock conflict is encountered during a transaction.
Let's consider an example:
A transaction has two statements that modify table t1, then table
t2, and then commits. The first statement of the transaction will
acquire a shared metadata lock on table t1, and it will be kept
utill COMMIT to ensure serializability.
At the moment when the second statement attempts to acquire a
shared metadata lock on t2, a concurrent ALTER or DROP statement
might have locked t2 exclusively. The prescription of the current
locking protocol is that the acquirer of the shared lock backs off
-- gives up all his current locks and retries. This implies that
the entire multi-statement transaction has to be rolled back.
- Incompatible change:
FLUSH commands such as FLUSH PRIVILEGES and FLUSH TABLES WITH READ
LOCK won't cause locked tables to be implicitly unlocked anymore.

which will be fixed by a subsequent backport.
mysql-test/r/ps.result:

and release it at the end. Thus PREPARE does not
accumulate metadata locks (Bug#989/WL#4284).

mysql-test/t/not_embedded_server.test:
Add a test case for Bug#989/WL#4284.
mysql-test/t/partition_innodb_semi_consistent.test:
Replace TRUNCATE with DELETE, to not issue
an implicit commit of a transaction, and not depend
on metadata locks.
mysql-test/t/partition_sync.test:
Temporarily disable the test case for Bug#43867,
which needs a fix to be backported from 6.0.
mysql-test/t/ps.test:
Add a test case for semantics of PREPARE and transaction-scope
locks: metadata locks on tables used in PREPARE are enclosed into a
temporary savepoint, taken at the beginning of PREPARE,
and released at the end. Thus PREPARE does not effect
what locks a transaction owns.
mysql-test/t/read_only_innodb.test:
Fix test case to reflect the fact that transactions now hold
metadata locks for the duration of a transaction
(Bug#989/WL#4284).

sending other concurrent statements that depend on its state.
mysql-test/t/xa.test:
Fix test case to reflect the fact that transactions now hold
metadata locks for the duration of a transaction
(Bug#989/WL#4284).
sql/ha_ndbcluster_binlog.cc:
Backport bits of changes of ha_ndbcluster_binlog.cc
from 6.0, to fix the failing binlog test suite with
WL#4284. WL#4284 implementation does not work
with 5.1 implementation of ndbcluster binlog index.
sql/log_event.cc:
Release metadata locks after issuing a commit.
sql/mdl.cc:
Style changes (WL#4284).
sql/mysql_priv.h:
Rename parameter to match the name used in the definition (WL#4284).
sql/rpl_injector.cc:
Release metadata locks on commit (WL#4284).
sql/rpl_rli.cc:
Remove assert made meaningless, metadata locks are released
at the end of the transaction.
sql/set_var.cc:
Close tables and release locks if autocommit mode is set.
sql/slave.cc:
Release metadata locks after a rollback.
sql/sql_acl.cc:
Don't implicitly unlock locked tables. Issue a implicit commit
at the end and unlock tables.
sql/sql_base.cc:
Defer the release of metadata locks when closing tables
if not required to.
Issue a deadlock error if the locking protocol requires
that a transaction re-acquire its locks.
Release metadata locks when closing tables for reopen.
sql/sql_class.cc:
Release metadata locks if the thread is killed.
sql/sql_parse.cc:
Release metadata locks after implicitly committing a active
transaction, or after explicit commits or rollbacks.
sql/sql_plugin.cc:
Allocate MDL request on the stack as the use of the table
is contained within the function. It will be removed from
the context once close_thread_tables is called at the end
of the function.
sql/sql_prepare.cc:
The problem is that the prepare phase of the CREATE TABLE
statement takes a exclusive metadata lock lock and this can
cause a self-deadlock the thread already holds a shared lock
on the table being that should be created.
The solution is to make the prepare phase take a shared
metadata lock when preparing a CREATE TABLE statement. The
execution of the statement will still acquire a exclusive
lock, but won't cause any problem as it issues a implicit
commit.
After some discussions with stakeholders it has been decided that
metadata locks acquired during a PREPARE statement must be released
once the statement is prepared even if it is prepared within a multi
statement transaction.
sql/sql_servers.cc:
Don't implicitly unlock locked tables. Issue a implicit commit
at the end and unlock tables.
sql/sql_table.cc:
Close table and release metadata locks after a admin operation.
sql/table.h:
The problem is that the prepare phase of the CREATE TABLE
statement takes a exclusive metadata lock lock and this can
cause a self-deadlock the thread already holds a shared lock
on the table being that should be created.
The solution is to make the prepare phase take a shared
metadata lock when preparing a CREATE TABLE statement. The
execution of the statement will still acquire a exclusive
lock, but won't cause any problem as it issues a implicit
commit.
sql/transaction.cc:
Release metadata locks after the implicitly committed due
to a new transaction being started. Also, release metadata
locks acquired after a savepoint if the transaction is rolled
back to the save point.
The problem is that in some cases transaction-long metadata locks
could be released before the transaction was committed. This could
happen when a active transaction was ended by a "START TRANSACTION"
or "BEGIN" statement, in which case the metadata locks would be
released before the actual commit of the active transaction.
The solution is to defer the release of metadata locks to after the
transaction has been implicitly committed. No test case is provided
as the effort to provide one is too disproportional to the size of
the fix.
Problem: Some system functions that could return different values on
master and slave were not marked unsafe. In particular:
GET_LOCK
IS_FREE_LOCK
IS_USED_LOCK
MASTER_POS_WAIT
RELEASE_LOCK
SLEEP
SYSDATE
VERSION
Fix: Mark these functions unsafe.
mysql-test/extra/rpl_tests/rpl_stm_000001.test:
- The test does not work in mixed mode any more, since it tries to
simulate an error in the sql thread in a query that uses get_lock.
Since get_lock now causes the query to be logged in row format,
the error didn't happen. Hence, we now force statement mode.
- Warnings must be disabled when the unsafe query is issued.
- Replaced some save_master_pos+connection slave+sync_with_master
by sync_slave_with_master.
mysql-test/suite/binlog/r/binlog_stm_mix_innodb_myisam.result:
updated result file
mysql-test/suite/binlog/r/binlog_stm_row.result:
updated result file
mysql-test/suite/binlog/r/binlog_unsafe.result:
updated result file
mysql-test/suite/binlog/t/binlog_killed.test:
binlog_killed only works in statement format now, since
it switches to row mode in mixed mode.
mysql-test/suite/binlog/t/binlog_stm_mix_innodb_myisam.test:
suppress warnings for unsafe statements
mysql-test/suite/binlog/t/binlog_stm_row.test:
- Suppress warnings in test that causes warnings.
- The test sets binlog format explicitly, so no need to execute it
twice.
mysql-test/suite/binlog/t/binlog_unsafe.test:
Added test for all unsafe system functions. This test also includes
system functions that were unsafe prior to BUG#47995.
mysql-test/suite/rpl/r/rpl_err_ignoredtable.result:
updated result file
mysql-test/suite/rpl/r/rpl_get_lock.result:

updated result file
mysql-test/suite/rpl/r/rpl_trigger.result:
updated result file
mysql-test/suite/rpl/t/rpl_err_ignoredtable.test:
- suppress warnings for unsafe statement
- replaced save_master_pos+connection slave+sync_with_master
with sync_slave_with_master
mysql-test/suite/rpl/t/rpl_get_lock.test:
update test case that causes new warnings
mysql-test/suite/rpl/t/rpl_nondeterministic_functions.test:
Added new test case for nondeterministic functions.
mysql-test/suite/rpl/t/rpl_trigger.test:
update test case that causes new warnings
sql/item_create.cc:
Marked some system functions unsafe.
sql/item_strfunc.cc:
Clarified comment related to this bug.
sql/sql_yacc.yy:
Marked sysdate unsafe.
One statement that have more than one different tables to update with
autoinc columns just was marked as unsafe in mixed mode, so the unsafe
warning can't be produced in statement mode.
To fix the problem, mark the statement as unsafe in statement mode too.
mysql-test/extra/rpl_tests/rpl_insert_id.test:
The test case is updated due to the patch of bug#45827.
mysql-test/suite/binlog/r/binlog_stm_mix_innodb_myisam.result:
The test result is updated due to the patch of bug#45827.
mysql-test/suite/binlog/r/binlog_unsafe.result:
Test result for bug#45827.
mysql-test/suite/binlog/t/binlog_unsafe.test:
Added test to verify if stmt that have more than one
different tables to update with autoinc columns will
produce unsafe warning
mysql-test/suite/rpl/r/rpl_stm_auto_increment_bug33029.result:

Non-transactional updates that take place inside a transaction present problems
for logging because they are visible to other clients before the transaction
is committed, and they are not rolled back even if the transaction is rolled
back. It is not always possible to log correctly in statement format when both
transactional and non-transactional tables are used in the same transaction.
In the current patch, we ensure that such scenario is completely safe under the
ROW and MIXED modes.
For application compatibility reasons MySQL converts "<autoincrement_column> IS NULL"
predicates to "<autoincrement_column> = LAST_INSERT_ID()" in the first SELECT following an
INSERT regardless of whether they're top level predicates or not. This causes wrong and
obscure results when these predicates are combined with others on the same columns. Fixed
by only doing the transformation on a single top-level predicate if a special SQL mode is
turned on (sql_auto_is_null).
Also made sql_auto_is_null off by default.

binlog, replication aborts
In SBR or MBR, the schema name is not being written to the binlog
when executing a LOAD DATA statement. This becomes a problem when
the current database (lets call it db1) is different from the
table's schema (lets call it db2). For instance, take the
following statements:
use db1;
load data local infile 'infile.txt' into table db2.t
Should this statement be logged without t's schema (db2), when
replaying it, one can get db1.t populated instead of db2.t (if
db1.t exists). On the other hand, if there is no db1.t at all,
replication will stop.
We fix this by always logging the table (in load file) with fully
qualified name when its schema is different from the current
database or when no default database was selected.

Backporting BUG#43789 to mysql-5.1-bugteam
The replication was generating corrupted data, warning messages on Valgrind
and aborting on debug mode while replicating a "null" to "not null" field.
Specifically the unpack_row routine, was considering the slave's table
definition and trying to retrieve a field value, where there was nothing to be
retrieved, ignoring the fact that the value was defined as "null" by the master.
To fix the problem, we proceed as follows:
1 - If it is not STRICT sql_mode, implicit default values are used, regardless
if it is multi-row or single-row statement.
2 - However, if it is STRICT mode, then a we do what follows:
2.1 If it is a transactional engine, we do a rollback on the first NULL that is
to be set into a NOT NULL column and return an error.
2.2 If it is a non-transactional engine and it is the first row to be inserted
with multi-row, we also return the error. Otherwise, we proceed with the
execution, use implicit default values and print out warning messages.
Unfortunately, the current patch cannot mimic the behavior showed by the master
for updates on multi-tables and multi-row inserts. This happens because such
statements are unfolded in different row events. For instance, considering the
following updates and strict mode:
(master)
create table t1 (a int);
create table t2 (a int not null);
insert into t1 values (1);
insert into t2 values (2);
update t1, t2 SET t1.a=10, t2.a=NULL;
t1 would have (10) and t2 would have (0) as this would be handled as a
multi-row update. On the other hand, if we had the following updates:
(master)
create table t1 (a int);
create table t2 (a int);
(slave)
create table t1 (a int);
create table t2 (a int not null);
(master)
insert into t1 values (1);
insert into t2 values (2);
update t1, t2 SET t1.a=10, t2.a=NULL;
On the master t1 would have (10) and t2 would have (NULL). On
the slave, t1 would have (10) but the update on t1 would fail.
Backporting BUG#38173 to mysql-5.1-bugteam
The reason of the bug was incompatibile with the master side behaviour.
INSERT query on the master is allowed to insert into a table without specifying
values of DEFAULT-less fields if sql_mode is not strict.
Fixed with checking sql_mode by the sql thread to decide how to react.
Non-strict sql_mode should allow Write_rows event to complete.
todo: warnings can be shown via show slave status, still this is a
separate rather general issue how to show warnings for the slave threads.
The BINLOG statement was sharing too much code with the slave SQL thread, introduced with
the patch for Bug#32407. This caused statements to be logged with the wrong server_id, the
id stored inside the events of the BINLOG statement rather than the id of the running
server.
Fix by rearranging code a bit so that only relevant parts of the code are executed by
the BINLOG statement, and the server_id of the server executing the statements will
not be overrided by the server_id stored in the 'format description BINLOG statement'.
mysql-test/extra/binlog_tests/binlog.test:
Added test to verify if the server_id stored in the 'format
description BINLOG statement' will override the server_id
of the server executing the statements.

The skip flag is no longer needed, as the code path for BINLOG statement has been
cleaned up.

Don't invoke the update_pos() code path for the BINLOG statement, as it contains code
that is redundant and/or harmful (especially setting thd->server_id).
