This patch clarifies some of the coding choices with documentationa and
removes a limitation in the code for future expansion of the CHAR and
BINARY fields to length > 255.


sql/field.cc:
  BUG#30790 : Suspicious code in rpl_utility.cc
  
  This patch adds an assertion to ensure we are not attempting to encode
  negative values.
sql/log_event.cc:
  BUG#30790 : Suspicious code in rpl_utility.cc
  
  This patch adds comments to help explain the choice of variable types.
sql/rpl_utility.cc:
  BUG#30790 : Suspicious code in rpl_utility.cc
  
  This patch removes code from the calc_field_size that is not needed and
  was ambiguous. Originally intended to future expansion, the code was
  not needed.
  
  Also added are comments to help explain some portions of the code.
  
  A change was made to the korr method to use the unsigned version to 
  avoid extended sign problems.
sql/rpl_utility.h:
  BUG#30790 : Suspicious code in rpl_utility.cc
  
  This patch corrects some type discrepencies and removes an extra cast.

mysql-test/suite/rpl_ndb/t/disabled.def:
  The rpl_ndb_2other test must be disabled until replication correctly
  handles endianess issues.

Removing unguarded read of slave_running field from inside
terminate_slave_threads(). This could cause premature exit in the event
that the slave thread already were shutting down, but isn't finished yet.

The fields slave_running, io_thd, and sql_thread are guarded by an
associated run_lock. A read of these fields were not guarded inside
terminate_slave_threads(), which caused an assertion to fire. The
assertion was removed, and the code reorganized slightly.


sql/slave.cc:
  Changing signature of terminate_slave_thread() to accept a skip_lock
  parameter instead of two mutexes. This mimics the signature of the
  terminate_slave_threads() function. Code is also changed as a result
  of this.
  
  Removing unguarded check of slave_running field in the master info and
  relay log info structure since that could cause premature exit of
  terminate_slave_threads().
  
  The thread variable for each of the slave threads can change before
  acquiring the run_lock mutex inside terminate_slave_thread(). Hence
  an assertion was removed that read the variable without guarding it
  with run_lock.
  
  Code that checked *slave_running status inside terminate_slave_thread()
  was reorganized slightly.
sql/slave.h:
  Moving terminate_slave_thread() to use internal linkage.

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).

  Results of the test.
mysql-test/suite/rpl_ndb/t/rpl_ndb_2other-slave.opt:
