711305e2c5 BUG#37426: RBR breaks for CHAR() UTF-8 fields > 85 chars 
In order to handle CHAR() fields, 8 bits were reserved for
the size of the CHAR field. However, instead of denoting the
number of characters in the field, field_length was used which
denotes the number of bytes in the field.

Since UTF-8 fields can have three bytes per character (and
has been extended to have four bytes per character in 6.0),
an extra two bits have been encoded in the field metadata
work for fields of type Field_string (i.e., CHAR fields).

Since the metadata word is filled, the extra bits have been
encoded in the upper 4 bits of the real type (the most 
significant byte of the metadata word) by computing the
bitwise xor of the extra two bits. Since the upper 4 bits
of the real type always is 1111 for Field_string, this 
means that for fields of length <256, the encoding is
identical to the encoding used in pre-5.1.26 servers, but
for lengths of 256 or more, an unrecognized type is formed,
causing an old slave (that does not handle lengths of 256
or more) to stop.


mysql-test/extra/rpl_tests/rpl_row_basic.test:
  Adding test cases for replicating UTF-8 fields of lengths
  of 256 or more (bytes).
mysql-test/suite/binlog/r/binlog_base64_flag.result:

mysql-test/suite/binlog/t/binlog_base64_flag.test:
  Adding tests to trigger check that an error is generated when replicating from a
  5.1.25 server for tables with a CHAR(128) but not when replicating a table with a
  CHAR(63). Although the bug indicates that the limit is 83, we elected to use CHAR(63)
  since 6.0 uses 4-byte UTF-8, and anything exceeding 63 would then cause the test to fail
  when the patch is merged to 6.0.

  applicable).

  is made to use lengths longer than supported.
  
  Extending compatible_field_size() function with an extra parameter
  holding a Relay_log_instace for error reporting.
  
  Field_string::compatible_field_size() now reports an error if field
  size for a CHAR is >255.
sql/field.h:
  Field length is now computed from most significant 4 bits
  of metadata word, or is equal to the row pack length if
  there is no metadata.
  
  Extending compatible_field_size() function with an extra parameter
  holding a Relay_log_instace for error reporting.
sql/rpl_utility.cc:
  Adding relay log parameter to compatible_field_size().
  
  Minor refactoring to eliminate duplicate code.
sql/slave.cc:
  Extending rpl_master_has_bug() with a single-argument predicate function and
  a parameter to the predicate function. The predicate function can be used to
  test for extra conditions for the bug before writing an error message.
sql/slave.h:
  Extending rpl_master_has_bug() with a single-argument predicate function and
  a parameter to the predicate function. The predicate function can be used to
  test for extra conditions for the bug before writing an error message.
  
  Also removing gratuitous default argument.

  Changing calls to rpl_master_has_bug() to adapt to changed signature.

f56d77dadf BUG#29020 (Event results not correctly replicated to slave in RBR): 
The bug allow multiple executing transactions working with non-transactional
to interfere with each others by interleaving the events of different trans-
actions.

Bug is fixed by writing non-transactional events to the transaction cache and
flushing the cache to the binary log at statement commit. To mimic the behavior
of normal statement-based replication, we flush the transaction cache in row-
based mode when there is no committed statements in the transaction cache,
which means we are committing the first one. This means that it will be written
to the binary log as a "mini-transaction" with just the rows for the statement.

Note that the changes here does not take effect when building the server with
HAVE_TRANSACTIONS set to false, but it is not clear if this was possible before
this patch either.

For row-based logging, we also have that when AUTOCOMMIT=1, the code now always
generates a BEGIN/COMMIT pair for single statements, or BEGIN/ROLLBACK pair in the
case of non-transactional changes in a statement that was rolled back. Note that
for the case where changes to a non-transactional table causes a rollback due
to error, the statement will now be logged with a BEGIN/ROLLBACK pair, even
though some changes has been committed to the non-transactional table.

875ad6d8b8 BUG#31168: @@hostname does not replicate 
Problem: in mixed and statement mode, a query that refers to a
system variable will use the slave's value when replayed on
slave. So if the value of a system variable is inserted into a
table, the slave will differ from the master.
Fix: mark statements that refer to a system variable as "unsafe",
meaning they will be replicated by row in mixed mode and produce a warning
in statement mode. There are some exceptions: some variables are actually
replicated. Those should *not* be marked as unsafe.
BUG#34732: mysqlbinlog does not print default values for auto_increment variables
Problem: mysqlbinlog does not print default values for some variables,
including auto_increment_increment and others. So if a client executing
the output of mysqlbinlog has different default values, replication will
be wrong.
Fix: Always print default values for all variables that are replicated.
I need to fix the two bugs at the same time, because the test cases would
fail if I only fixed one of them.

mysql-test/suite/rpl/t/rpl_skip_error.test:
  The test used @@server_id, which is not safe to replicate, so it would
  have given a warning. The way it used @@server_id was hackish (issue a
  query on master that removes rows only on master), so I replaced it by a
  more robust way to do the same thing (connect to slave and insert the
  rows only there).
  Also clarified what the test case does.
mysql-test/t/mysqlbinlog2.test:
  Use --short-form instead of manually filtering out nondeterministic stuff
  from mysqlbinlog (because we added the nondeterministic @@pseudo_thread_id
  to the output).
sql/item_func.cc:
  Added method of Item_func_get_system_var that indicates whether the given
  system variable will be written to the binlog or not.
sql/item_func.h:
  Added method of Item_func_get_system_var that indicates whether the given
  system variable will be written to the binlog or not.
sql/log_event.cc:
   - auto_increment_offset was not written to the binlog if
  auto_increment_increment=1
   - mysqlbinlog did not output default values for some variables
  (BUG#34732). In st_print_event_info, we remember for each variable whether
  it has been printed or not. This is achieved in different ways for
  different variables:
      - For auto_increment_*, lc_time_names, charset_database_number,
        we set the default values in st_print_event_info to something
        illegal, so that it will look like they have changed the first time
        they are seen.
      - For charset, sql_mode, pseudo_thread_id, we add a flag to
        st_print_event_info which indicates whether the variable has been
        printed.
      - Since pseudo_thread_id is now printed more often, and its value is
        not guaranteed to be constant across different runs of the same
        test script, I replaced it by a constant if --short-form is used.
   - Moved st_print_event_info constructor from log_event.h to log_event.cc,
  since it now depends on ILLEGAL_CHARSET_NUMBER, which is defined in
  m_ctype.h, which is better to include from a .cc file than from a header
  file.
sql/log_event.h:
  Added fields to st_print_event_info that indicate whether some of the
  variables have been written or not. Since the initialization of
  charset_database_number now depends on ILLEGAL_CHARSET_INFO_NUMBER, which
  is defined in a header file, which we'd better not include from this
  header file -- I moved the constructor from here to log_event.cc.
sql/set_var.cc:
  System variables now have a flag binlog_status, which indicates if they
  are written to the binlog. If nothing is specified, all variables are
  marked as not written to the binlog (NOT_IN_BINLOG) when created. In this
  file, the variables that are written to the binlog are marked with
  SESSION_VARIABLE_IN_BINLOG.
sql/set_var.h:
  Added flag binlog_status to class sys_var. Added a getter and a
  constructor parameter that sets it.
  Since I had to change sys_var_thd_enum constructor anyways, I simplified
  it to use default values of arguments instead of three copies of the
  constructor.
sql/sql_yacc.yy:
  Mark statements that refer to a system variable as "unsafe",
  meaning they will be replicated by row in mixed mode. Added comment to
  explain strange piece of code just above.
mysql-test/include/diff_tables.inc:

8d37a30eac BUG#32407: Impossible to do point-in-time recovery from older binlog 
Problem: it is unsafe to read base64-printed events without first
reading the Format_description_log_event (FD).  Currently, mysqlbinlog
cannot print the FD.

As a side effect, another bug has also been fixed: When mysqlbinlog
--start-position=X was specified, no ROLLBACK was printed. I changed
this, so that ROLLBACK is always printed.

This patch does several things:

 - Format_description_log_event (FD) now print themselves in base64
   format.

 - mysqlbinlog is now able to print FD events.  It has three modes:
    --base64-output=auto    Print row events in base64 output, and print
                            FD event.  The FD event is printed even if
                            it is outside the range specified with
                            --start-position, because it would not be
                            safe to read row events otherwise. This is
                            the default.

    --base64-output=always  Like --base64-output=auto, but also print
                            base64 output for query events.  This is
                            like the old --base64-output flag, which
                            is also a shorthand for
                            --base64-output=always

    --base64-output=never   Never print base64 output, generate error if
                            row events occur in binlog.  This is
                            useful to suppress the FD event in binlogs
                            known not to contain row events (e.g.,
                            because BINLOG statement is unsafe,
                            requires root privileges, is not SQL, etc)

 - the BINLOG statement now handles FD events correctly, by setting
   the thread's rli's relay log's description_event_for_exec to the
   loaded event.

   In fact, executing a BINLOG statement is almost the same as reading
   an event from a relay log.  Before my patch, the code for this was
   separated (exec_relay_log_event in slave.cc executes events from
   the relay log, mysql_client_binlog_statement in sql_binlog.cc
   executes BINLOG statements).  I needed to augment
   mysql_client_binlog_statement to do parts of what
   exec_relay_log_event does.  Hence, I did a small refactoring and
   moved parts of exec_relay_log_event to a new function, which I
   named apply_event_and_update_pos.  apply_event_and_update_pos is
   called both from exec_relay_log_event and from
   mysql_client_binlog_statement.

 - When a non-FD event is executed in a BINLOG statement, without
   previously executing a FD event in a BINLOG statement, it generates
   an error, because that's unsafe.  I took a new error code for that:
   ER_NO_FORMAT_DESCRIPTION_EVENT_BEFORE_BINLOG_STATEMENTS.

   In order to get a decent error message containing the name of the
   event, I added the class method char*
   Log_event::get_type_str(Log_event_type type), which returns a
   string name for the given Log_event_type.  This is just like the
   existing char* Log_event::get_type_str(), except it is a class
   method that takes the log event type as parameter.

   I also added PRE_GA_*_ROWS_LOG_EVENT to Log_event::get_type_str(),
   so that names of old rows event are properly printed.

 - When reading an event, I added a check that the event type is known
   by the current Format_description_log_event. Without this, it may
   crash on bad input (and I was struck by this several times).

 - I patched the following test cases, which all contain BINLOG
   statements for row events which must be preceded by BINLOG
   statements for FD events:
    - rpl_bug31076

While I was here, I fixed some small things in log_event.cc:

 - replaced hard-coded 4 by EVENT_TYPE_OFFSET in 3 places

 - replaced return by DBUG_VOID_RETURN in one place

 - The name of the logfile can be '-' to indicate stdin.  Before my
   patch, the code just checked if the first character is '-'; now it
   does a full strcmp().  Probably, all arguments that begin with a -
   are already handled somewhere else as flags, but I still think it
   is better that the code reflects what it is supposed to do, with as
   little dependencies as possible on other parts of the code.  If we
   one day implement that all command line arguments after -- are
   files (as most unix tools do), then we need this.

I also fixed the following in slave.cc:

 - next_event() was declared twice, and queue_event was not static but
   should be static (not used outside the file).


client/client_priv.h:
  Declared the new option for base64 output.
client/mysqlbinlog.cc:
   - Change from using the two-state command line option
    "default/--base64-output" to the three-state
    "--base64-output=[never|auto|always]"
   - Print the FD event even if it is outside the --start-position range.
   - Stop if a row event is about to be printed without a preceding FD
     event.
   - Minor fixes:
      * changed 4 to EVENT_TYPE_OFFSET in some places
      * Added comments
      * before, "mysqlbinlog -xyz" read from stdin; now it does not
        (only "mysqlbinlog -" reads stdin).
mysql-test/r/mysqlbinlog2.result:
  Updated result file: mysqlbinlog now prints ROLLBACK always.
mysql-test/suite/binlog/t/disabled.def:
  The test must be disabled since it reveals another bug: see BUG#33247.
mysql-test/suite/rpl/r/rpl_bug31076.result:
  Updated result file
mysql-test/suite/rpl/r/rpl_row_mysqlbinlog.result:
  Updated result file
mysql-test/suite/rpl/t/rpl_bug31076.test:
  Had to add explicit Format_description_log_event before other BINLOG
  statements
mysql-test/t/mysqlbinlog2.test:
  we must suppress base64 output in result file because it contains a
  timestamp
sql/log_event.cc:
   - Made FD events able to print themselves
   - Added check that the current FD event knows about the event type, when
     an event is about to be read. (Hint to reviewers: I had to re-indent
     a big block because of this; use diff -b)
      * To get a decent error message, I also added a class method
        const char* Log_event::get_type_str(Log_event_type)
        which converts number to event type string without having a
        Log_event object.
      * Made Log_event::get_type_str aware of PRE_GA_*_ROWS_LOG_EVENT.
   - Minor fixes:
      * Changed return to DBUG_VOID_RETURN
sql/log_event.h:
   - Declared enum to describe the three base64_output modes
   - Use the enum instead of a flag
   - Declare the new class method get_type_str (see log_event.cc)
sql/share/errmsg.txt:
  Added error msg.
sql/slave.cc:
   - Factored out part of exec_relay_log_event to the new function
     apply_event_and_update_pos, because that code is needed when executing
     BINLOG statements. (this is be functionally equivalent to the
     previous code, except: (1) skipping events is now optional, controlled
     by a parameter to the new function (2) the return value of
     exec_relay_log_event has changed; see next item).
   - Changed returned error value to always be 1. Before, it would return
     the error value from apply_log_event, which was unnecessary. This
     change is safe because the exact return value of exec_relay_log_event
     is never examined; it is only tested to be ==0 or !=0.
   - Added comments describing exec_relay_log_event and
     apply_event_and_update_pos.
   - Minor fixes:
      * Removed duplicate declaration of next_event, made queue_event
        static.
      * Added doxygen code to include this file.
sql/slave.h:
  Declared the new apply_event_and_update_pos
sql/sql_binlog.cc:
   - Made mysql_binlog_statement set the current FD event when the given
     event is an FD event. This entails using the new function
     apply_event_and_update_pos from slave.cc instead of just calling the
     ev->apply method.
   - Made mysql_binlog_statement fail if the first BINLOG statement is not
     an FD event.
mysql-test/suite/binlog/r/binlog_base64_flag.result:
  New test file needs new result file
mysql-test/suite/binlog/t/binlog_base64_flag.test:
  Added test case to verify that:
   - my patch fixes the bug
   - the new --base64-output flag works as expected
   - base64 events not preceded by an FD event give an error
   - an event of a type not known by the current FD event fails cleanly.
