Removed get_table_def() as it is not needed and it causes a copying of
a Table_map_log_event that can be avoided.
In general one should avoid putting big object on stack, especially if
they have to be copied to other locations. This can cause issues with
object that has pointers to itself or allocated memory, which is
common for any object that uses things like intrusive lists.
* Log rows in online_alter_binlog.
* Table online data is replicated within dedicated binlog file
* Cached data is written on commit.
* Versioning is fully supported.
* Works both wit and without binlog enabled.
* For now savepoints setup is forbidden while ONLINE ALTER goes on.
Extra support is required. We can simply log the SAVEPOINT query events
and replicate them together with row events. But it's not implemented
for now.
* Cache flipping:
We want to care for the possible bottleneck in the online alter binlog
reading/writing in advance.
IO_CACHE does not provide anything better that sequential access,
besides, only a single write is mutex-protected, which is not suitable,
since we should write a transaction atomically.
To solve this, a special layer on top Event_log is implemented.
There are two IO_CACHE files underneath: one for reading, and one for
writing.
Once the read cache is empty, an exclusive lock is acquired (we can wait
for a currently active transaction finish writing), and flip() is emitted,
i.e. the write cache is reopened for read, and the read cache is emptied,
and reopened for writing.
This reminds a buffer flip that happens in accelerated graphics
(DirectX/OpenGL/etc).
Cache_flip_event_log is considered non-blocking for a single reader and a
single writer in this sense, with the only lock held by reader during flip.
An alternative approach by implementing a fair concurrent circular buffer
is described in MDEV-24676.
* Cache managers:
We have two cache sinks: statement and transactional.
It is important that the changes are first cached per-statement and
per-transaction.
If a statement fails, then only statement data is rolled back. The
transaction moves along, however.
Turns out, there's no guarantee that TABLE well persist in
thd->open_tables to the transaction commit moment.
If an error occurs, tables from statement are purged.
Therefore, we can't store te caches in TABLE. Ideally, it should be
handlerton, but we cut the corner and store it in THD in a list.
1. Change m_size to uint. This removes some implicit conversions.
See unpack_row, for instance:
uint max_cols= MY_MIN(tabledef->size(), cols->n_bits);
2. Improve table_def memory layout by reordering columns
If replication breaks in GTID mode, it is not trivial to determine the GTID of
the failing event group. This is a problem, as such GTID is needed eg. to
explicitly set @@gtid_slave_pos to skip to after that event group, or to
compare errors on different servers, etc.
Fix by ensuring that relevant slave errors logged to the error log include the
GTID of the event group containing the problem event.
The merge is still missing a few hunks related to temporary tables and
InnoDB log file size. The associated code did not seem to exist in
10.0, so the merge of that needs more work. Until this is fixed, there
are a number of test failures as a result.
includes:
* remove some remnants of "Bug#14521864: MYSQL 5.1 TO 5.5 BUGS PARTITIONING"
* introduce LOCK_share, now LOCK_ha_data is strictly for engines
* rea_create_table() always creates .par file (even in "frm-only" mode)
* fix a 5.6 bug, temp file leak on dummy ALTER TABLE
Problem:
=======
The return value from my_b_write is ignored by: `my_b_write_quoted',
`my_b_write_bit',`Query_log_event::print_query_header'
Most callers of `my_b_printf' ignore the return value. `log_event.cc'
has many calls to it.
Analysis:
========
`my_b_write' is used to write data into a file. If the write fails it
sets appropriate error number and error message through my_error()
function call and sets the IO_CACHE::error == -1.
`my_b_printf' function is also used to write data into a file, it
internally invokes my_b_write to do the write operation. Upon
success it returns number of characters written to file and on error
it returns -1 and sets the error through my_error() and also sets
IO_CACHE::error == -1. Most of the event specific print functions
for example `Create_file_log_event::print', `Execute_load_log_event::print'
etc are the ones which make several calls to the above two functions and
they do not check for the return value after the 'print' call. All the above
mentioned abuse cases deal with the client side.
Fix:
===
As part of bug fix a check for IO_CACHE::error == -1 has been added at
a very high level after the call to the 'print' function. There are
few more places where the return value of "my_b_write" is ignored
those are mentioned below.

BUG#11761686 insert_id event is not filtered.
Two issues are covered.
INSERT into autoincrement field which is not the first part in the composed primary key
is unsafe by autoincrement logging design. The case is specific to MyISAM engine
because Innodb does not allow such table definition.
However no warnings and row-format logging in the MIXED mode was done, and
that is fixed.
Int-, Rand-, User-var log-events were not filtered along with their parent
query that made possible them to screw up execution context of the following
query.
Fixed with deferring their execution until the parent query.

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.

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.

using TPC-B):
Problem: A RBR event can contain incomplete row data (only key value and
fields which have been changed). In that case, when the row is unpacked
into record and written to a table, the missing fields get incorrect NULL
values leading to master-slave inconsistency.
Solution: Use values found in slave's table for columns which are not given
in the rows event. The code for writing a single row uses the following
algorithm:
1. unpack row_data into table->record[0],
2. try to insert record,
3. if duplicate record found, fetch it into table->record[0],
4. unpack row_data into table->record[0],
5. write table->record[0] into the table.
Where row_data is the row as stored in the data area of a rows event.
Thus:
a) unpacking of row_data happens at the time when row is written into
a table,
b) when unpacking (in step 4), only columns present in row_data are
overwritten - all other columns remain as they were found in the table.
Since all data needed for the above algorithm is stored inside
Rows_log_event class, functions which locate and write rows are turned
into methods of that class.
replace_record() -> Rows_log_event::write_row()
find_and_fetch_row() -> Rows_log_event::find_row()
Both methods take row data from event's data buffer - the row being
processed is pointed by m_curr_row. They unpack the data as needed into
table's record buffers record[0] or record[1]. When row is unpacked,
m_curr_row_end is set to point at next row in the data buffer.
Other changes introduced in this changeset:
- Change signature of unpack_row(): don't report errors and don't
setup table's rw_set here. Errors can happen only when setting default
values in prepare_record() function and are detected there.
- In Rows_log_event and derived classes, don't pass arguments to
the execution primitives (do_...() member functions) but use class
members instead.
- Move old row handling code into log_event_old.cc to be used by
*_rows_log_event_old classes.
Also, a new test rpl_ndb_2other is added which tests basic replication
from master using ndb tables to slave storing the same tables using
(possibly) different engine (myisam,innodb).
Test is based on existing tests rpl_ndb_2myisam and rpl_ndb_2innodb.
However, these tests doesn't work for various reasons and currently are
disabled (see BUG#19227).
The new test differs from the ones it is based on as follows:
1. Single test tests replication with different storage engines on slave
(myisam, innodb, ndb).
2. Include file extra/rpl_tests/rpl_ndb_2multi_eng.test containing
original tests is replaced by extra/rpl_tests/rpl_ndb_2multi_basic.test
which doesn't contain tests using partitioned tables as these don't work
currently. Instead, it tests replication to a slave which has more or
less columns than master.
3. Include file include/rpl_multi_engine3.inc is replaced with
include/rpl_multi_engine2.inc. The later differs by performing slightly
different operations (updating more than one row in the table) and
clearing table with "TRUNCATE TABLE" statement instead of "DELETE FROM"
as replication of "DELETE" doesn't work well in this setting.
4. Slave must use option --log-slave-updates=0 as otherwise execution of
replication events generated by ndb fails if table uses a different
storage engine on slave (see BUG#29569).
sql/log_event.cc:
- Initialization of new Rows_log_event members.
- Fixing some typos in documentation.
In Rows_log_event::do_apply_event:
- Set COMPLETE_ROWS_F flag (when master and slave have the same number of
columns and all colums are present in the row)
- Move initialization of tables write/read sets here, outside the rows
processing loop (and out of unpack_row() function).
- Remove calls to do_prepare_row() - no longer needed.
- Add code managing m_curr_row and m_curr_row_end pointers.
- Change signatures of row processing methods of Rows_log_event and it
descendants - now most arguments are taken from class members.
- Remove do_prepare_row() methods which are no longer used.
- The auto_afree_ptr template is moved to rpl_utility.h (so that it can
be used in log_event_old.cc).
- Removed copy_extra_fields() function - no longer used.
In Rows_log_event::write_row (former replace_record):
- The old code is moved to log_event_old.cc.
- Use prepare_record() and non-destructive unpack_current_row() to fill record
with data.
- In case a record being inserted already exists on slave and row data is
incomplete use the record found and non-destructive unpack_current_row() to
combine new column values with existing ones.
- More debug info added.
In Rows_log_event::find_row (former find_and_fetch_row function):
- The old code is moved to log_event_old.cc.
- Unpacking of the row is moved here.
- In case of search using PK, the key data is prepared here.
- More debug info added.
- Remove initialization of Rows_log_event::m_after_image buffer which is no
longer used.
- Use new row unpacking methods in Update_rows_log_event::do_exec_row() to
create before and after image.
Note: all existing code used by Rows_log_event::do_apply_event() has been moved
to log_event_old.cc to be used by *_rows_log_event_old classes.
sql/log_event.h:
- Add new COMPLETE_ROWS_F flag in Rows_log_event.
- Add Rows_log_event members describing the row being processed.
- Add a pointer to key buffer which is used in derived classes.
- Add new methods: find__row(), write_row() and unpack_current_row().
- Change signatures of do_...() methods (replace method arguments by
class members).
- Remove do_prepare_row() method which is no longer used.
- Update method documentation.
- Add Old_rows_log_event class, which contains the old row processing code, as
a friend of Rows_log_event so that it can access all members of an event
instance.
sql/log_event_old.cc:
Move here old implementation of Rows_log_event::do_apply_event() and
helper methods.
sql/log_event_old.h:
- Define new class Old_rows_log_event encapsulating old version of
Rows_log_event::do_apply_event() and the helper methods.
- Add the Old_rows_log_event class as a base for *_old versions of RBR event
classes, ensure that the old version of do_apply_event() is called.
- For *_old classes, declare the helper methods used in the old version of
do_apply_event().
sql/rpl_record.cc:
- Make unpack_row non-destructive for columns not present in the row.
- Don't fill read/write set here as it is done outside these functions.
- Move initialization of a record with default values to a separate
function prepare_record().
sql/rpl_record.h:
- Change signature of unpack_row().
- Declare function prepare_record().
sql/rpl_utility.cc:
Make tabe_def::calc_field_size() a const method.
sql/rpl_utility.h:
Make table_def::calc_field_size() a const method.
Move auto_afree_ptr template here so that it can be re-used (currently
in log_event.cc and log_event_old.cc). Similar with DBUG_PRINT_BITSET
macro.
mysql-test/extra/rpl_tests/rpl_ndb_2multi_basic.test:
Modification of rpl_ndb_2multi_eng test. Tests with partitioned tables
are removed and a setup with slave having different number of columns
than master is added.
mysql-test/include/rpl_multi_engine2.inc:
Modification of rpl_multi_engine3.inc which operates on more rows and
replaces "DELETE FROM t1" with "TRUNCATE TABLE t1" as the first form
doesn't replicate in NDB -> non-NDB setting (BUG#28538).
mysql-test/suite/rpl_ndb/r/rpl_ndb_2other.result:
Results of the test.
mysql-test/suite/rpl_ndb/t/rpl_ndb_2other-slave.opt:
Test options. --log-slave-updates=0 is compulsory as otherwise non-NDB
slave applying row events from NDB master will fail when trying to log
them.
mysql-test/suite/rpl_ndb/t/rpl_ndb_2other.test:
Test replication of NDB table to slave using other engine. The main test
is in extra/rpl_tests/rpl_ndb_2multi_basic.test. It is included here
several times with different settings of default storage engine on slave.
(and be more friendly to Doxygen by removing unnecessary typedefs).

BUG#22086 : Extra Slave Col: Char(5) on slave and Char(10) on master cause mysqld crash
This patch refactors the calc_field_size() method to use the new
methods implemented in the field classes. It also corrects comments
concerning how replication of field metadata works.
sql/log_event.h:
BUG#22086 : Extra Slave Col: Char(5) on slave and Char(10) on master cause mysqld crash
This patch refactors out the calc_field_size() method into the method
save_field_metadata().
sql/rpl_utility.cc:
BUG#22086 : Extra Slave Col: Char(5) on slave and Char(10) on master cause mysqld crash
This patch adds a method to check the size of the field on the master
using the field metadata from WL#3228. Each column is checked to ensure
the slave's column is >= to the master's column in size.
sql/rpl_utility.h:
BUG#22086 : Extra Slave Col: Char(5) on slave and Char(10) on master cause mysqld crash
This patch changes the table_def class so that it records the size of
the metadata. This is a result of refactoring out the calc_field_size()
method into the method save_field_metadata(). Prevents access via
field_metadata(col) to unitialized memory when there is no metadata
transmitted from the master.

Minor refactoring.
This patch adds the ability to store extra field metadata in the table
map event. This data can include pack_length() or field_lenght() for
fields such as CHAR or VARCHAR enabling developers to add code that
can check for compatibilty between master and slave columns. More
importantly, the extra field metadata can be used to store data from the
master correctly should a VARCHAR field on the master be <= 255 bytes
while the same field on the slave is > 255 bytes.
The patch also includes the needed changes to unpack to ensure that data
which is smaller on the master can be unpacked correctly on the slave.
WL#3915 : (NDB) master's cols > slave
Slave starts accepting and handling rows of master's tables which have more columns.
The most important part of implementation is how to caclulate the amount of bytes to
skip for unknown by slave column.

sql/field.cc:
WL#3228 : RBR using different table defs on slave/master
This patch includes updates to the unpack() methods for the variable
length fields. A new parameter was added (from_length) that is the
value stored in the field_metadata of the table map from the table_def
class. If the value is non-zero and less than what the field on the
slave is then use the from_length else use the original value from the
field on the slave.
sql/field.h:
L#3228 : RBR using different table defs on slave/master
This patch includes updates to the unpack() methods for the variable
length fields. A new parameter was added (from_length) that is the
value stored in the field_metadata of the table map from the table_def
class.
sql/log_event.cc:
WL#3228 : RBR using different table defs on slave/master
This patch adds methods to calculate the field metadata size, prepare
the field metadata for writing to the binlog, and additions to the
Table_map_log_event::write_body method to include the field metadata
in the table map that is written to the binlog.
WL#3915 master's cols > slave
copying extra (slave's) fields returns early if master's table version is wider;
removing assert in the way of master > slave cols.
sql/log_event.h:
WL#3228 : RBR using different table defs on slave/master
This patch adds method declarations and variables needed to support
storing field metadata in the table map that is written to the binlog.
sql/rpl_record.cc:
WL#3228 : RBR using different table defs on slave/master
This patch modifies the unpack_row() method to unpack fields passing in
the value from the table_def class. This value is the extra field
metadata stored there from the master.
WL#3915 master's cols > slave
adding a snippet that shift exectution curson donw the row skipping unknown by slave
fields' data.
sql/rpl_rli.h:
WL#3228 : RBR using different table defs on slave/master
This patch adds a helper function to retrieve the table_def for a given
table in the RPL_TABLE_LIST structure.
sql/rpl_utility.cc:
WL#3228 : RBR using different table defs on slave/master
This patch adds a helper method that retrieves the correct size
parameter for the field. This method is used to compare the size as
sent by the master with that on the slave for all types of fields that
can vary in size and storage requirements.
WL#3915 master's cols > slave
Remove warning message for master's cols > slave.
sql/rpl_utility.h:
WL#3228 : RBR using different table defs on slave/master
This patch changes the table_def class constructor to pass in the raw
data read from the table map and extract it into an array of dimension
size (number of fields). It also adds a method to return the field
metadata for any field. The method returns the data stored in the table
map or 0 if no data was stored for that field. Lastly, a method to return
the results of field->maybe_null() is included so that the slave can
determine if a field that is not on the slave is null.
mysql-test/suite/rpl/t/rpl_colSize.test:
WL#3228 : RBR using different table defs on slave/master
