This patch adds options to annotate the binlog (and the mysqlbinlog
output) with the original SQL query for queries that are logged
using row-based replication.
This patch improves the selection of index to use to apply row-based
DELETE and UPDATE events on tables with no primary key (original code
picks the first index unconditionally).
If ANALYZE TABLE is done, the index cardinalities will be compared and
the best index will be used.
Fixes some problems in the original patch:
- Without ANALYZE TABLE, rec_per_key statistics is not available; in this
case the original patch could choose a really bad index, even ignoring
a primary key.
- The original patch did not consider multi-column keys correctly, and
could thus pick a less desirable single-column key over a good
multi-column index.
Also fixes Bug#58997, and adds test cases.
Normally, auto_increment value is generated for the column by
inserting either NULL or 0 into it. NO_AUTO_VALUE_ON_ZERO
suppresses this behavior for 0 so that only NULL generates
the auto_increment value. This behavior is also followed by
a slave, specifically by the SQL Thread, when applying events
in the statement format from a master. However, when applying
events in the row format, the flag was ignored thus causing
an assertion failure:
"Assertion failed: next_insert_id == 0, file .\handler.cc"
In fact, we never need to generate a auto_increment value for
the column when applying events in row format on slave. So we
don't allow it to happen by using 'MODE_NO_AUTO_VALUE_ON_ZERO'.
Refactoring: Get rid of all the sql_mode checks to rows_log_event
when applying it for avoiding problems caused by the inconsistency
of the sql_mode on slave and master as the sql_mode is not set for
Rows_log_event.
mysql-test/extra/rpl_tests/rpl_auto_increment.test:
Added test to verify if the assertion of "next_insert_id == 0"
will fail in ha_external_lock() function.
mysql-test/suite/rpl/r/rpl_auto_increment.result:
Test result for bug#56662.
sql/log_event.cc:
Added code to not allow generation of auto_increment value when
processing rows event by adding 'MODE_NO_AUTO_VALUE_ON_ZERO' to
sql_mode.
sql/rpl_record.cc:
Added code to get rid of the 'MODE_STRICT_TRANS_TABLES' and
MODE_STRICT_ALL_TABLES check to the table when appling the
rows event and treat it as no strict.
Open issues:
- A better fix for #57688; Igor is working on this
- Test failure in index_merge_innodb.test ; Igor promised to look at this
- Some Innodb tests fails (need to merge with latest xtradb) ; Kristian promised to look at this.
- Failing tests: innodb_plugin.innodb_bug56143 innodb_plugin.innodb_bug56632 innodb_plugin.innodb_bug56680 innodb_plugin.innodb_bug57255
- Werror is disabled; Should be enabled after merge with xtradb.
Suprisingly, a Slave_log_event would show up in the binary
log. This event is never used and should not appear in the
logs. As such, when the slave (or the mysqlbinlog tool) reads the
event, it will hit an invalid pointer (reference to the
descriptor event when deserializing the Slave_log_event was
purposodely set to NULL).
The presence of the Slave_log_event denotes a corrupted log, but
we cannot tell how the log got corrupted in the first
place. However, we can make the server cope with such events when
it reads them - in case of log corruption - and fail gracefully.
This patch makes the server/mysqlbinlog to report that it has
found an invalid log event when Slave_log_event is read.

When mysqlbinlog was given the --database=X flag, it always printed
'ROLLBACK TO', but the corresponding 'SAVEPOINT' statement was not
printed. The replicated filter(replicated-do/ignore-db) and binlog
filter (binlog-do/ignore-db) has the same problem. They are solved
in this patch together.
After this patch, We always check whether the query is 'SAVEPOINT'
statement or not. Because this is a literal check, 'SAVEPOINT' and
'ROLLBACK TO' statements are also binlogged in uppercase with no
any comments.
The binlog before this patch can be handled correctly except one case
that any comments are in front of the keywords. for example:
/* bla bla */ SAVEPOINT a;
/* bla bla */ ROLLBACK TO a;
for InnoDB
The class Field_bit_as_char stores the metadata for the
field incorrecly because bytes_in_rec and bit_len are set
to (field_length + 7 ) / 8 and 0 respectively, while
Field_bit has the correct values field_length / 8 and
field_length % 8.
Solved the problem by re-computing the values for the
metadata based on the field_length instead of using the
bytes_in_rec and bit_len variables.
To handle compatibility with old server, a table map
flag was added to indicate that the bit computation is
exact. If the flag is clear, the slave computes the
number of bytes required to store the bit field and
compares that instead, effectively allowing replication
*without conversion* from any field length that require
the same number of bytes to store.

When replicating from 4.1 master to 5.0 slave START SLAVE UNTIL can stop too late.
The necessary in calculating of the beginning of an event the event's length
did not correspond to the master's genuine information at the event's execution time.
That piece of info was changed at the event's relay-logging due to binlog_version<4 event
conversion by IO thread.
Fixed with storing the master genuine Query_log_event size into a new status
variable at relay-logging of the event. The stored info is extacted at the event
execution and participate further to caclulate the correct start position of the event
in the until-pos stopping routine.
The new status variable's algorithm will be only active when the event comes
from the master of version < 5.0 (binlog_version < 4).

b. the converted event is read out and the stored size is engaged in the start pos calculation.
The new status is active only for events that IO thread instantiates for the sake of the conversion.

Augmenting the Query_log_event with a new member to hold a value to store/extact from the status
var of the event packet header.
- Marked a couple of tests with --big
- Fixed xtradb/handler/ha_innodb.cc to call explain_filename()
storage/xtradb/handler/ha_innodb.cc:
Call explain_filename() to get proper names for partitioned tables
'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.
- Moved some code from innodb_plugin to xtradb, to ensure that all tests runs
- Did changes in pbxt and maria storage engines becasue of changes in thd->query
- Reverted wrong code in sql_table.cc for how ROW_FORMAT is used.
This is a re-commit of Monty's merge to eliminate an extra commit from
MySQL-5.1.42 that was accidentally included in the merge.
This is a merge of the MySQL 5.1.41 clone-off (clone-5.1.41-build). In
case there are any extra changes done before final MySQL 5.1.41
release, these will need to be merged later before MariaDB 5.1.41
release.

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.
Add rewrite_db() member to the Table_map_log_event class.
Each RBR-event in binary log is preceded by a Table_map event
containing a (db_id, db_name) pair. The rewrite_db(new_name)
function replaces db_name by new_name in a buffer containing
Table_map event read from the binary log.
"load data" statements were written to the binlog as a mix of the original statement
and bits recreated from parse-info. This relied on implementation details and broke
with IGNORE_SPACES and versioned comments.
We now completely resynthesize the query for LOAD DATA for binlog (which among other
things normalizes them somewhat with regard to case, spaces, etc.).
We have already parsed the query properly, so we make use of that rather
than mix-and-match string literals and parsed items.
This should make us safe with regard to versioned comments, even those
spanning multiple tokens. Also no longer affected by IGNORE_SPACES.

clean up Load_log_event::print_query and friends so they don't print
excess spaces. add support for printing charset names to print_query.
sql/log_event.h:
We already have three places where we synthesize LOAD DATA queries.
Better use one of those!
sql/sql_lex.h:
When binlogging LOAD DATA statements, we make up the statement to
be logged (from the parse-info, rather than substrings of the
original query) now. Consequently, we no longer need (string-)
pointers into the original query.
sql/sql_load.cc:
Completely rewrote write_execute_load_query_log_event() to synthesize the
LOAD DATA statement wholesale, rather than piece it together from
synthesized bits and literal excerpts from the original query. This
will not only give us a nice, normalized statement (all uppercase,
no excess spaces, etc.), it will also handle comments, including
versioned comments right, which is certainly more than we can say
about the previous incarnation.
sql/sql_yacc.yy:
We're no longer assembling LOAD DATA statements from bodyparts of the
original query, so some bookkeeping in the parser can go.
* Finished Monty and Jani's merge
* Some InnoDB tests still fail (because it's old xtradb code run against
newer testsuite). They are expected to go after mergning with the latest
xtradb.

mysqlbinlog --database parameter was being ignored when processing
row events. As such no event filtering would take place.
This patch addresses this by deploying a call to shall_skip_database
when table_map_events are handled (as these contain also the name of
the database). All other rows events referencing the table id for the
filtered map event, will also be skipped.
client/mysqlbinlog.cc:
Added shall_skip_database call to the part of the code that handles
Table_map_log_events. It inspects the database name and decides whether
to filter the event or not. Furthermore, if table map event is filtered
next events referencing the table id in the table map event, will also
be filtered.
mysql-test/suite/binlog/t/binlog_row_mysqlbinlog_db_filter.test:
Test case that checks if row events are actually filtered out.
sql/log_event.h:
Added a map for holding the currently ignored table map events.
Table map events are inserted when they shall be skipped and removed
once the last row event in the statement is processed.
Make the caller of Query_log_event, Execute_load_log_event
constructors and THD::binlog_query to provide the error code
instead of having the constructors to figure out the error code.
