  Bug #12917164 DROP USER CAN'T DROP USERS WITH LEGACY 
      UPPER CASE HOST NAME ANYMORE
  
  Description:
  It is not possible to drop users with host names with upper case
  letters in them. i.e DROP USER 'root'@'Tmp_Host_Name'; is failing
  with error.
  
  Analysis: Since the fix 11748570 we came up with lower case hostnames
  as standard. But in the current bug the hostname is created by
  mysql_install_db script is still having upper case hostnames. 
  So, if we have the hostname with upper case letters like(Tmp_Host_Name)
  then we will have as it is stored in the mysql.user table. 
  In this case if use "'DROP USER 'root'@'Tmp_Host_Name';" it gives 
  error because we do compare with the lower case of hostname since the 
  11748570 fix.
  
  Fix: We need to convert the hostname to lower case before storing into 
  the mysql.user table when we run the mysql_install_db script.

  Bug#17559867 AFTER REBUILDING,A MYISAM PARTITION ENDS UP 
               AS A INNODB PARTITTION.
  
  PROBLEM
  -------
  The correct engine_type was not being set during 
  rebuild of the partition due to which the handler
  was always created with the default engine,
  which is innodb for 5.5+ ,therefore even if the
  table was myisam, after rebuilding the partitions
  ended up as innodb partitions.
  
  FIX
  ---
  Set the correct engine type during rebuild.

message:
  Bug#17234370 LAST_INSERT_ID IS REPLICATED INCORRECTLY IF
  REPLICATION FILTERS ARE USED.
  
  Problem:
  When Filtered-slave applies Int_var_log_event and when it
  tries to write the event to its own binlog, LAST_INSERT_ID
  value is written wrongly.
  
  Analysis:
  THD::stmt_depends_on_first_successful_insert_id_in_prev_stmt
  is a variable which is set when LAST_INSERT_ID() is used by
  a statement. If it is set, first_successful_insert_id_in_
  prev_stmt_for_binlog will be stored in the statement-based
  binlog. This variable is CUMULATIVE along the execution of
  a stored function or trigger: if one substatement sets it
  to 1 it will stay 1 until the function/trigger ends,
  thus making sure that first_successful_insert_id_in_
  prev_stmt_for_binlog does not change anymore and is
  propagated to the caller for binlogging. This is achieved
  using the following code
  if(!stmt_depends_on_first_successful_insert_id_in_prev_stmt)               
  {                                                                           
    /* It's the first time we read it */                                      
    first_successful_insert_id_in_prev_stmt_for_binlog=                       
    first_successful_insert_id_in_prev_stmt;                                
    stmt_depends_on_first_successful_insert_id_in_prev_stmt= 1;               
  }
  
  Slave server, after receiving Int_var_log_event event from
  master, it is setting
  stmt_depends_on_first_successful_insert_id_in_prev_stmt
  to true(*which is wrong*) and not setting
  first_successful_insert_id_in_prev_stmt_for_binlog. Because
  of this problem, when the actual DML statement with
  LAST_INSERT_ID() is parsed by slave SQL thread,
  first_successful_insert_id_in_prev_stmt_for_binlog is not
  set. Hence the value zero (default value) is written to
  slave's binlog.
  
  Why only *Filtered slave* is effected when the code is
  in common place:
  -------------------------------------------------------
  In Query_log_event::do_apply_event,
  THD::stmt_depends_on_first_successful_insert_id_in_prev_stmt
  is reset to zero at the end of the function. In case of
  normal slave (No Filters), this variable will be reset. 
  In Filtered slave, Slave SQL thread defers all IRU events's
  execution until IRU's Query_log event is received. Once it
  receives Query_log_event it executes all pending IRU events
  and then it executes Query_log_event. Hence the variable is
  not getting reset to 0, causing this bug.
  
  Fix: As described above, the root cause was setting 
  THD::stmt_depends_on_first_successful_insert_id_in_prev_stmt
  when Int_var_log_event was executed by a SQL thread. Hence
  removing the problematic line from the code.

  Bug#16900358 FIX FOR CVE-2012-5611 IS INCOMPLETE
  
  Description: Fix for bug CVE-2012-5611 (bug 67685) is 
  incomplete. The ACL_KEY_LENGTH-sized buffers in acl_get() and 
  check_grant_db() can be overflown by up to two bytes. That's 
  probably not enough to do anything more serious than crashing 
  mysqld.
  Analysis: In acl_get() when "copy_length" is calculated it 
  just adding the variable lengths. But when we are using them 
  with strmov() we are adding +1 to each. This will lead to a 
  three byte buffer overflow (i.e two +1's at strmov() and one 
  byte for the null added by strmov() function). Similarly it 
  happens for check_grant_db() function as well.
  Fix: We need to add "+2" to "copy_length" in acl_get() 
  and "+1" to "copy_length" in check_grant_db().

  WL#7266: Dump-thread additional concurrency tests                                                                                                                           
  
  This worklog aims at testing the two following scenarios:
  
  1) Whenever the mysql_binlog_send method (dump thread)
  reaches the end of file when reading events from the binlog, before
  checking if it should wait for more events, there was a test to
  check if the file being read was still active, i.e, it was the last
  known binlog. However, it was possible that something was written to
  the binary log and then a rotation would happen, after EOF was
  detected and before the check for active was performed. In this
  case, the end of the binary log would not be read by the dump
  thread, and this would cause the slave to lose updates.
  This test verifies that the problem has been fixed. It waits during
  this window while forcing a rotation in the binlog.
  
  2) Verify dump thread can send events in active file, correctly after
  encountering an IO error.
