           STRING_RESULT argument

There is a "magic" number for precision : NOT_FIXED_DEC. 
This means that the precision is not a fixed number.
But this constant was re-defined in several files and 
was not available to the UDF developers.
 
Moved the NOT_FIXED_DEC definition to the correct header
and removed the redundant definitions.

  Bug#27249 table_wild with alias: select t1.* as something

  Aliases to table wildcards are silently ignored, but they should
  not be allowed as it is non-standard and currently useless. There
  is not point in having a alias to a wildcard of column names.

  The solution is to rewrite the select_item rule so that aliases
  for table wildcards are not accepted.

  Bug#41860: Without Windows named pipe

  The problem was that the patch for Bug#10374 broke named pipe
  and shared memory transports on Windows due to a failure to
  implement a dummy poll method for transports other than BSD
  sockets. Another problem was that mysqltest lacked support
  for named pipe and shared memory connections, which lead to
  misleading test cases that were supposed run common queries
  over both transports.

  The solution is to properly implement, at the VIO layer, the
  poll and is_connected methods. The is_connected method is
  implemented for every suppported transport and the poll one
  only where it makes sense. Furthermore, support for named pipe
  and shared memory connections is added to mysqltest as to
  enable testing of both transports using the test suite.

  The problem is that the server doesn't detect aborted connections which

  The solution is to peek at the connection every five seconds to verify if

  Bug#27525 table not found when using multi-table-deletes with aliases over several databas
  Bug#30234 Unexpected behavior using DELETE with AS and USING

  The multi-delete statement has a documented limitation that
  cross-database multiple-table deletes using aliases are not
  supported because it fails to find the tables by alias if it
  belongs to a different database. The problem is that when
  building the list of tables to delete from, if a database
  name is not specified (maybe an alias) it defaults to the
  name of the current selected database, making impossible to
  to properly resolve tables by alias later. Another problem
  is a inconsistency of the multiple table delete syntax that
  permits ambiguities in a delete statement (aliases that refer
  to multiple different tables or vice-versa).

  The first step for a solution and proper implementation of
  the cross-databse multiple table delete is to get rid of any
  ambiguities in a multiple table statement. Currently, the parser
  is accepting multiple table delete statements that have no obvious
  meaning, such as:

  DELETE a1 FROM db1.t1 AS a1, db2.t2 AS a1;
  DELETE a1 AS a1 FROM db1.t1 AS a1, db2.t2 AS a1;

  The solution is to resolve the left part of a delete statement
  using the right part, if the a table on right has an alias,
  it must be referenced in the left using the given alias. Also,
  each table on the left side must match unambiguously only one
  table in the right side.

  Bug#36649: Condition area is not properly cleaned up after stored routine invocation

  The problem is that the diagnostics area of a trigger is not
  isolated from the area of the statement that caused the trigger
  invocation. In MySQL terms, it means that warnings generated
  during the execution of the trigger are not removed from the
  "warning area" at the end of the execution.

  Before this fix, the rules for MySQL message list life cycle (see
  manual entry for SHOW WARNINGS) did not apply to statements
  inside stored programs:

    - The manual says that the list of messages is cleared by a
      statement that uses a table (any table). However, such
      statement, if run inside a stored program did not clear the
      message list.
    - The manual says that the list is cleared by a statement that
      generates a new error or a warning, but this was not the case
      with stored program statements either and is changed to be the
      case as well.

  In other words, after this fix, a statement has the same effect
  on the message list regardless of whether it's executed inside a
  stored program/sub-statement or not.

  This introduces an incompatible change:

    - before this fix, a, e.g. statement inside a trigger could
      never clear the global warning list
    - after this fix, a trigger that generates a warning or uses a
      table, clears the global warning list
    - however, when we leave a trigger or a function, the caller's
      warning information is restored (see more on this below).

  This change is not backward compatible as it is intended to make
  MySQL behavior similar to the SQL standard behavior:

  A stored function or trigger will get its own "warning area" (or,
  in standard terminology, diagnostics area).  At the beginning of
  the stored function or trigger, all messages from the caller area
  will be copied to the area of the trigger.  During execution, the
  message list will be cleared according to the MySQL rules
  described on the manual (SHOW WARNINGS entry).  At the end of the
  function/trigger, the "warning area" will be destroyed along with
  all warnings it contains, except that if the last statement of
  the function/trigger generated messages, these are copied into
  the "warning area" of the caller.

  Consequently, statements that use a table or generate a warning
  *will* clear warnings inside the trigger, but that will have no
  effect to the warning list of the calling (outer) statement.

  Bug#41971: Thread state on embedded server is always "Writing to net"
 
  The problem is that the state of a thread on a embedded server is
  always displayed as "Writing to net", which is wrong as there is
  no "network" in the embedded server.

  The solution is only exclude, on a embedded server, the thread
  state conditions that are related to network operations. Other
  thread states related to waiting on conditions or other operations
  are preserved.

sql/sql_show.cc:
  Unroll conditionals into a function. Skip check for network

  command to retrieve the command directly from the thread
  handle -- they have the same value.

Added this option, named as "--dump-slave". The purpose of this option is to be
able to produce a dump from a slave used for making backups of the master. Originally,
dumping from the main master was fine, but as more data accumulated, the dump process
would take over 30 minutes, locking up the master database hence website for 30 minutes.
A slave dedicated to producing backups was the answer, but I needed a dump that could be

used to restore a slave instantly and in order to do that, it has to have three things 
contained in the dump:
  
  1. "STOP SLAVE;" at the beginning
  2. "CHANGE MASTER TO ...<the master - info from 'show slave status'>"
  3. "START SLAVE;" at the end
  
These options in this changeset contain this.
  
  --stop-slave adds "STOP SLAVE" to the beginning of the dump and "STOP SLAVE" 
  to the end of the dump.
  
  --include-host gives the user the option to have the host explicitely added
  to the "CHANGE MASTER TO ..." line.
  
  --dump-slave adds the "CHANGE MASTER ..." to the dump representing not the slave's
  master binlog info, but the slave's master's info from "SHOW SLAVE STATUS" 


client/client_priv.h:
  Added OPT_SLAVE_DATA to client_priv.h
client/mysqldump.c:
  * Added --dump-slave option (name per Brian)
  * Added --stop-slave to print "STOP SLAVE;" into the dump
  * Added --include-host option to include "MASTER_HOST=..." and "MASTER_PORT=..."
    to the dump since unlike --master-data, the host can't be assumed to be
    the local host
  * Added do_start_slave and do_stop_slave to stop the slave sql thread upon
    start of the dump process, and to start the slave sql upon finish of dump process -
    to keep the log information frozen during this time.
  * Added do_show_slave_status for obtaining slave information needed to compose 
    "CHANGE MASTER ..." output to the master of this slave.
  * Added necessary long options and defines required for new options

  
Feature from Eric Bergen, CLA signed 2007-06-27.
  
Adds new mysql client option "--auto-vertical-output", which causes

Otherwise, it sends normal tabular results.

client/mysql.cc:
  Add another command-line option, "auto-vertical-output".
      
  Add functions to get the terminal width and functions to get the widths of fields.
      
  Use them together to emit vertical output when some output table is too wide to
  fit in the terminal.  If the terminal doesn't support reading its width, then assume
  80-positions wide.
mysql-test/r/mysql.result:
  Show that various select statements do work as expected.  Wide tables become vertical
  and narrow ones do not.

  Show that various select statements do work as expected.

           deadlocks

Backport of revno: 2617.68.35

The problem was that if one connection is running a multi-statement 
transaction which involves a single partitioned table, and another 
connection attempts to alter the table to drop a non-existing partition,
(which of course will fail), the first connection still gets 
ER_LOCK_DEADLOCK and cannot proceed anymore.

This bug is no longer reproducable. This has also been tested with the
patch for Bug#46654 "False deadlock on concurrent DML/DDL with partitions, 
inconsistent behavior" which concerned a similar problem but where the 
ALTER TABLE is semantically correct.

Test case added in partition_sync.test.
