exactly it's mapped to "ALTER TABLE t; ANALYZE TABLE t;"


sql/ha_innodb.cc:
  ::optimize() now returns "try ALTER and then analyze" instead of only analyze.
sql/handler.h:
  new code to say "try alter and analyze".
sql/mysql_priv.h:
  as we may now use mysql_alter_table() internally to ::optimize we must prevent it from talking to the client.
  New function mysql_recreate_table() which is the same as ALTER TABLE t;
sql/sql_parse.cc:
  the big block removed here is moved into mysql_recreate_table().
sql/sql_table.cc:
  In mysql_admin_table(): if the handler returns HA_ADMIN_TRY_ALTER,
  we close the table, recreate it, then open it and analyze it.
  This is currently used only for OPTIMIZE TABLE of an InnoDB table.

New option --sync-binlog=x (and global settable variable) which will fsync the binlog
after every x-th disk write to it. That is, if in autocommit mode, after every x-th statement
written to the binlog; if using transactions, after every x-th transaction written to the binlog.
x==0 means no fsync. x==1 is the slowest.
There is no test added for this, I have just checked that it works as --sync-binlog=1 dramatically
slows down mysqld.
Made sync-frm a global settable variable.

  every sync_binlog_period-th disk binlog write, we fsync the binlog

error messages when a query goes wrong.
Note that from now on, if you run with --slave-skip-error=xx, then nothing will
be printed to the error log when the slave is having this error xx and
skipping it (but you don't care as you want to skip it).


sql/repl_failsafe.cc:

The bug was caused by error in hash calculation function: it
always returned hash value for last field in a composite key, so 
for keys like (a text, b char(1)) we were always
getting bad hash values.
 


myisam/mi_unique.c:
  Fix for bug #3904:
  We should take into account existing hash value when calculating hash for
  next key in a composite unique index.

binlog even if they changed nothing, and a test for this.
This is useful when users use these commands to clean up their master and slave by issuing
one command on master (assume master and slave have slightly different data for some
reason and you want to clean up both).
Note that I have not changed multi-table DELETE and multi-table UPDATE because their
error-reporting mechanism is more complicated.

is broken (prepared statements)": fixed date handling in many places 
of prepared statements code.


libmysql/libmysql.c:
  Fix for Bug#4026:
  - now buffer_length is defined for any buffer type. Network buffer 
    preallocation cleaned up.
  - added constants for maximum buffer sizes necessary for MYSQL_TYPE_DATE,
    MYSQL_TYPE_TIME, MYSQL_TYPE_DATETIME types.
  - TIME/DATETIME packing/unpacking functions fixed 
  - now result set metadata is always updated from fields sent to COM_EXECUTE.
    This is necessary to make 'SELECT ?' queries work without conversions.
sql/item.cc:
  - added implementatoin of Item_param::get_date
sql/item.h:
  - added enum_field_types Item_param::param_type. First step for proper
    handling of placeholders.
  - added get_date() implementation to prevent date -> string -> date 
    conversions when MYSQL_TYPE_DATE/DATETIME parameter is used in temporal 
    context.
sql/protocol.cc:
  Fix for Bug#4026:
  - PACKET_BUFFET_EXTRA_ALLOC -> PACKET_BUFFER_EXTRA_ALLOC.
    The define itself was moved to .cc as it's used only in protocol.cc
  - fixed Protocol_prep::store_time() call.
sql/protocol.h:
  - PACKET_BUFFER_EXTRA_ALLOC moved to protocol.cc
sql/sql_prepare.cc:
  Fix for Bug#4026:
  - MYSQL_TYPE_TIME/DATETIME handling fixed.

In mysqlbinlog, there was a problem with how we escaped the content of a string user variable.
To be perfect, we should have escaped with character_set_client. But this charset is unknown
to mysqlbinlog. So the simplest is to print the string in hex. This is unreadable but
100% safe with any charset (checked with Bar), no more need to bother with character_set_client.
