968ec5eacc BUG#43264 Test rpl_trigger is failing randomly w/ use of copy_file in 5.0
The test case fails sporadically on Windows while trying to overwrite an unused
binary log. The problem stems from the fact that MySQL on Windows does not
immediately unlock/release a file while the process that opened and closed it is
still running. In BUG 38603, this issue was circumvented by stopping the MySQL
process, copying the file and then restarting the MySQL process. 

Unfortunately, such facilities are not available in the 5.0.  Other approaches
such as stopping the slave and issuing change master do not work because the relay
log file and index are not closed when a slave is stopped. So to fix the problem,
we simply don't run on windows the part of the test that was failing.

4e95179af9 Bug# 30946: mysqldump silently ignores --default-character-set
when used with --tab

1) New syntax: added CHARACTER SET clause to the
  SELECT ... INTO OUTFILE (to complement the same clause in
  LOAD DATA INFILE).
  mysqldump is updated to use this in --tab mode.

2) ESCAPED BY/ENCLOSED BY field parameters are documented as
   accepting CHAR argument, however SELECT .. INTO OUTFILE
   silently ignored rests of multisymbol arguments.
   For the symmetrical behavior with LOAD DATA INFILE the
   server has been modified to fail with the same error:

     ERROR 42000: Field separator argument is not what is
                  expected; check the manual

3) Current LOAD DATA INFILE recognizes field/line separators
   "as is" without converting from client charset to data
   file charset. So, it is supposed, that input file of
   LOAD DATA INFILE consists of data in one charset and
   separators in other charset. For the compatibility with
   that [buggy] behaviour SELECT INTO OUTFILE implementation
   has been saved "as is" too, but the new warning message
   has been added:

     Non-ASCII separator arguments are not fully supported

   This message warns on field/line separators that contain
   non-ASCII symbols.


client/mysqldump.c:
  mysqldump has been updated to call SELECT ... INTO OUTFILE
  statement with a charset from the --default-charset command
  line parameter.
mysql-test/r/mysqldump.result:
  Added test case for bug #30946.

mysql-test/t/mysqldump.test:
  Added test case for bug #30946.
mysql-test/t/outfile_loaddata.test:
  Added test case for bug #30946.
sql/field.cc:
  String conversion code has been moved from check_string_copy_error()
  to convert_to_printable() for reuse.
sql/share/errmsg.txt:
  New WARN_NON_ASCII_SEPARATOR_NOT_IMPLEMENTED message has been added.
sql/sql_class.cc:
  The select_export::prepare() method has been modified to:
  
    1) raise the ER_WRONG_FIELD_TERMINATORS error on multisymbol
       ENCLOSED BY/ESCAPED BY field arguments like LOAD DATA INFILE;
  
    2) warn with a new WARN_NON_ASCII_SEPARATOR_NOT_IMPLEMENTED
       message on non-ASCII field or line separators.
  
  The select_export::send_data() merhod has been modified to
  convert item data to output charset (see new SELECT INTO OUTFILE
  syntax). By default the BINARY charset is used for backward
  compatibility.
sql/sql_class.h:
  The select_export::write_cs field added to keep output
  charset.
sql/sql_load.cc:
  mysql_load has been modified to warn on non-ASCII field or
  line separators with a new WARN_NON_ASCII_SEPARATOR_NOT_IMPLEMENTED
  message.
sql/sql_string.cc:
  New global function has been added: convert_to_printable()
  (common code has been moved from check_string_copy_error()).
sql/sql_string.h:
  New String::is_ascii() method and new global convert_to_printable()
  function have been added.
sql/sql_yacc.yy:
  New syntax: added CHARACTER SET clause to the
  SELECT ... INTO OUTFILE (to complement the same clause in
  LOAD DATA INFILE). By default the BINARY charset is used for
  backward compatibility.

7d8b967a86 Bug#46265: Can not disable warning about unsafe statements for binary logging
If using statement based replication (SBR), repeatedly calling
statements which are unsafe for SBR will cause a warning message
to be written to the error for each statement. This might lead
to filling up the error log and there is no way to disable this
behavior.

The solution is to only log these message (about statements unsafe
for statement based replication) if the log_warnings option is set.

For example:

SET GLOBAL LOG_WARNINGS = 0;
INSERT INTO t1 VALUES(UUID());
SET GLOBAL LOG_WARNINGS = 1;
INSERT INTO t1 VALUES(UUID());

In this case the message will be printed only once:

[Warning] Statement may not be safe to log in statement format.
          Statement: INSERT INTO t1 VALUES(UUID())

mysql-test/suite/binlog/r/binlog_stm_unsafe_warning.result:
  Add test case result for Bug#46265
mysql-test/suite/binlog/t/binlog_stm_unsafe_warning-master.opt:
  Make log_error value available.
mysql-test/suite/binlog/t/binlog_stm_unsafe_warning.test:

sql/sql_class.cc:
  Print warning only if the log_warnings is enabled.

0d61bd9dce Bug#45800 crash when replacing into a merge table and there is a duplicate
A REPLACE in the MERGE engine is actually a REPLACE
into one (FIRST or LAST) of the underlying MyISAM
tables. So in effect the server works on the meta
data of the MERGE table, while the real insert happens
in the MyISAM table.

The MERGE table has no index, while MyISAM has a
unique index. When a REPLACE into a MERGE table (
and the REPLACE conflicts with a duplicate in a
child table) is done, we try to access the duplicate
key information for the MERGE table. This information
actually does not exist, hence this results in a crash.

The problem can be resolved by modifying the MERGE
engine to provide us the duplicate key information
directly, instead of just returning the MyISAM index
number as the error key. Then the SQL layer (or "the
server") does not try to access the key_info of the
MERGE table, which does not exist.

The current patch modifies the MERGE engine to provide
the position for a record where a unique key violation
occurs.

include/myisammrg.h:
  Bug#45800 crash when replacing into a merge table and there is a duplicate
  
  Add a member to the st_mymerge_info structure that will
  store the duplicate key offset in the MERGE table. This
  offset will be the sum of the record offset of the MyISAM
  table within the MERGE table and the offset of the record
  within the MyISAM table.

  Bug#45800 crash when replacing into a merge table and there is a duplicate

storage/myisammrg/myrg_info.c:
  Bug#45800 crash when replacing into a merge table and there is a duplicate
  
  We modify the myrg_status function to return the position of the
  duplicate key. The duplicate key position in the MERGE table will
  be the MyISAM file_offset and the offset within the MyISAM table
  of the start position of the records.

fc1acef6b2 Bug#44521 Executing a stored procedure as a prepared statement can sometimes cause
an assertion in a debug build.

The reason is that the C API doesn't support multiple result sets for prepared
statements and attempting to execute a stored routine which returns multiple result
sets sometimes lead to a network error. The network error sets the diagnostic area
prematurely which later leads to the assert when an attempt is made to set a second
server state.

This patch fixes the issue by changing the scope of the error code returned by
sp_instr_stmt::execute() to include any error which happened during the execution.
To assure that Diagnostic_area::is_sent really mean that the message was sent all
network related functions are checked for return status.

043e09b543 BUG#41166 stored function requires "deterministic" if binlog_format is "statement"
If the log_bin_trust_function_creators option is not defined, creating a stored
function requires either one of the modifiers DETERMINISTIC, NO SQL, or READS
SQL DATA. Executing a stored function should also follows the same rules if in
STATEMENT mode. However, this was not happening and a wrong error was being
printed out: ER_BINLOG_ROW_RBR_TO_SBR.

The patch makes the creation and execution compatible and prints out the correct
error ER_BINLOG_UNSAFE_ROUTINE when a stored function without one of the modifiers
above is executed in STATEMENT mode.

cf505e4494 BUG#43046: mixed mode switch to row format with temp table lead
to wrong result
      
When using MIXED mode and issuing 'CREATE TEMPORARY TABLE t_tmp',
the statement is logged if the current binlogging mode is
STATEMENT. This causes the slave to replay the instruction and
create the temporary table as well. If there is no switch to ROW
mode, and later on a 'DROP TEMPORARY TABLE t_tmp' is issued, then
this statement will also be logged and the slave will
remove/close the temporary table.
      
However, if there is a switch to ROW mode between the CREATE and
DROP TEMPORARY table, the DROP statement will not be logged,
leaving the slave with a dangling temporary table.
      
This patch addresses this, by always logging a DROP TEMPORARY
TABLE IF EXISTS when in mixed mode and a drop statement is issued
for temporary table(s).

  Updated result file.

8ec2f3d0d1 Bug#43587: Putting event_scheduler=1 in init SQL file crashes
mysqld

The problem was that enabling the event scheduler inside a init
file caused the server to crash upon start-up. The crash occurred
because the event scheduler wasn't being initialized before the
commands in the init-file are processed.

The solution is to initialize the event scheduler before the init
file is read. The patch also disables the event scheduler during
bootstrap and makes the bootstrap operation robust in the
presence of background threads.

>   we have table_list->table == 0 and 
>   table_list->table->'any method' call leads to crash.
>   The fix is to perform table_list->table->file->extra()
>   method for all tables belonging to view.

>   Bug #44810: index merge and order by with low sort_buffer_size
>   crashes server!
>   
>   The problem affects the scenario when index merge is followed by a filesort
>   and the sort buffer is not big enough for all the sort keys.
>   In this case the filesort function will read the data to the end through the 
>   index merge quick access method (and thus closing the cursor etc), 
>   but will leave the pointer to the quick select method in place.
>   It will then create a temporary file to hold the results of the filesort and
>   will add it as a sort output file (in sort.io_cache).
>   Note that filesort will copy the original 'sort' structure in an automatic
>   variable and restore it after it's done.
>   As a result at exiting filesort() we have a sort.io_cache filled in and 
>   nothing else (as a result of close of the cursors at end of reading data 
>   through index merge).
>   Now create_sort_index() will note that there is a select and will clean it up
>   (as it's been used already by filesort() reading the data in). While doing that
>   a special case in the index merge destructor will clean up the sort.io_cache,
>   assuming it's an output of the index merge method and is not needed anymore.
>   As a result the code that tries to read the data back from the filesort output 
>   will get no data in both memory and disk and will crash.
>         
>   Fixed similarly to how filesort() does it : by copying the sort.io_cache structure
>   to a local variable, removing the pointer to the io_cache (so that it's not freed 
>   by QUICK_INDEX_MERGE_SELECT::~QUICK_INDEX_MERGE_SELECT) and restoring the original 
>   structure (together with the valid pointer) after the cleanup is done.
>   This is a safe thing to do because all the structures are already cleaned up by
>   hitting the end of the index merge's read method (QUICK_INDEX_MERGE_SELECT::get_next()) 
>   and the cleanup code being written in a way that tolerates repeating cleanups.

f16fe16db0 BUG#46129 Failing mixed stm (with trans and non-trans tables) causes wrong seq in
binlog
      
The fix for BUG 43929 introduced a regression issue. In a nutshell, when a
statement that changes a non-transactional table fails, it is written to the
binary log with the error code appended. Unfortunately, after BUG 43929, this
failure was flushing the transactional chace causing mismatch between execution
and logging histories. To fix this issue, we avoid flushing the transactional
cache when a commit or rollback is not issued.
