Changes in the InnoDB codebase required to compile and
integrate the MEB codebase with MySQL 5.5.

@ storage/innobase/btr/btr0btr.c
  Excluded buffer pool usage from MEB build.
 
  buf_pool_from_bpage calls are in buf0buf.ic, and
  the buffer pool functions from that file are
  disabled in MEB.
@ storage/innobase/buf/buf0buf.c
  Disabling more buffer pool functions unused in MEB.
@ storage/innobase/dict/dict0dict.c
  Disabling dict_ind_free that is unused in MEB.
@ storage/innobase/dict/dict0mem.c
  The include

  #include "ha_prototypes.h"

  Was causing conflicts with definitions in my_global.h

  Linking C executable mysqlbackup

  innobase_get_lower_case_table_names
  innobase_casedn_str
  are functions that are part of ha_innodb.cc that is not part of the build
        
  dict_mem_foreign_table_name_lookup_set
  function is not there in the current codebase, meaning we do not use it in MEB.
@ storage/innobase/fil/fil0fil.c
  The srv_fast_shutdown variable is declared in
  srv0srv.c that is not compiled in the
  mysqlbackup codebase.

  This throws an undeclared error.

  From the Manual
  ---------------

  innodb_fast_shutdown
  --------------------

  The InnoDB shutdown mode. The default value is 1
  as of MySQL 3.23.50, which causes a “fast� shutdown
  (the normal type of shutdown). If the value is 0,
  InnoDB does a full purge and an insert buffer merge
  before a shutdown. These operations can take minutes,
  or even hours in extreme cases. If the value is 1,
  InnoDB skips these operations at shutdown.

  This ideally does not matter from mysqlbackup

Patch for 5.1 and 5.5: fix typo in byte comparison in rr_cmp()

Followup patch: wrong result unless archive storage engine is available.

WHEN KILLING

Suppose there is a query waiting for a lock.  If the user kills
this query, then "Got error -1 when reading table" error message
must not be logged in the server log file.  Since this is a user
requested interruption, no spurious error message must be logged
in the server log.  This patch will remove the error message from
the log.

    message:
      Bug#13417754 ASSERT IN ROW_DROP_DATABASE_FOR_MYSQL DURING DROP SCHEMA
      
      This assert could be triggered if an InnoDB table was being moved
      to a different database using ALTER TABLE ... RENAME, while this
      database concurrently was being dropped by DROP DATABASE.
      
      The reason for the problem was that no metadata lock was taken
      on the target database by ALTER TABLE ... RENAME.
      DROP DATABASE was therefore not blocked and could remove
      the database while ALTER TABLE ... RENAME was executing. This
      could cause the assert in InnoDB to be triggered.
      
      This patch fixes the problem by taking a IX metadata lock on
      the target database before ALTER TABLE ... RENAME starts
      moving a table to a different database.
      
      Note that this problem did not occur with RENAME TABLE which
      already takes the correct metadata locks.
      
      Also note that this patch slightly changes the behavior of
      ALTER TABLE ... RENAME. Before, the statement would abort and
      return an error if a lock on the target table name could not
      be taken immediately. With this patch, ALTER TABLE ... RENAME
      will instead block and wait until the lock can be taken 
      (or until we get a lock timeout). This also means that it is
      possible to get ER_LOCK_DEADLOCK errors in this situation
      since we allow ALTER TABLE ... RENAME to wait and not just
      abort immediately.

Problem: mysqlbinlog exits without any error code in case of
file write error. It is because of the fact that the calls
to Log_event::print() method does not return a value and the
thus any error were being ignored.

Resolution: We resolve this problem by checking for the 
IO_CACHE::error == -1 after every call to Log_event:: print()
and terminating the further execution.

Analysis:
-------------
If server is started with limit of MAX_CONNECTIONS and 
MAX_USER_CONNECTIONS then only MAX_USER_CONNECTIONS of any particular
users can be connected to server and total MAX_CONNECTIONS of client can
be connected to server.

Server maintains a counter for total CONNECTIONS and total CONNECTIONS 
from particular user.

Here, MAX_CONNECTIONS of connections are created to server. Out of this
MAX_CONNECTIONS, connections from particular user (say USER1) are
also created. The connections from USER1 is lesser than 
MAX_USER_CONNECTIONS. After that there was one more connection request from
USER1. Since USER1 can still create connections as he havent reached
MAX_USER_CONNECTIONS, server increments counter of CONNECTIONS per user.
As server already has MAX_CONNECTIONS of connections, next check to total
CONNECTION count fails. In this case control is returned WITHOUT 
decrementing the CONNECTIONS per user. So the counter per user CONNECTIONS goes
on incrementing for each attempt until current connections are closed. 
And because of this counter per CONNECTIONS reached MAX_USER_CONNECTIONS. 
So, next connections form USER1 user always returns with MAX_USER_CONNECTION 
limit error, even when total connection to sever are less than MAX_CONNECTIONS.

Fix:
-------------
This issue is occurred because of not handling counters properly in the
server. Changed the code to handle per user connection counters properly.

Details:
 - Archive storage engine file access were not instrumented and thus
   were not shown in PS tables.
      
Fix:
 - Added instrumentation code by using PS Apis for I/O.

This bug was introduced in early stages of plugin. We were not
checking for an implicit lock on sec index rec for trx_id that is
stamped on current version of the clust_index in case where the
clust_index has a previous delete marked version.

IN THE ERROR LOG
      
Problem:
Using mysqlbinlog with the --read-from-remote-server option as shown below
prints a message in error log for each call. This happens for 5.5 and above
versions
      
mysqlbinlog -uroot -p --read-from-remote-server --host=localhost test
      
Message in error log file is given below:
120312 10:27:57 [Note] Start binlog_dump to slave_server(0), pos(test, 4)
      
The problem is that it can fill up the error log if the command is called
very often.
      
Analysis:
The below mentioned print function is called from "mysql_binlog_send" function
which causes the "Start binlog_dump..." string to be printed in error log file.

sql_print_information("Start binlog_dump to master_thread_id(%lu) 
slave_server(%d)..."
      
Fix:
A condition has been added in such a way that the 'sql_print_information' 
will be invoked only when the "log_warnings" variable is set to >1 
otherwise don't call the 'sql_print_information' function.

Print deprecation warning if the --safe-mode command line option is
used.

so that investigating test failures is easier.

Detect cases when @before_count / @after_count is NULL.

updating the result file.  Because a multi-row insert now reserves the
auto increment values before hand, if any explicitly specified auto
increment values are there, then some of the reserved values are lost.

INNODB_AUTOINC_LOCK_MODE=1 AND USING TRIGGER

When an insert stmt like "insert into t values (1),(2),(3)" is
executed, the autoincrement values assigned to these three rows are
expected to be contiguous.  In the given lock mode
(innodb_autoinc_lock_mode=1), the auto inc lock will be released
before the end of the statement.  So to make the autoincrement
contiguous for a given statement, we need to reserve the auto inc
values at the beginning of the statement.  

Modified the fix based on review comment by Svoj.  

This is a followup to the fix for Bug#12340997
get_interval_value() was trying to parse the input string,
looking for leading '-' while skipping whitespace.
The macro my_isspace() does not work for utf32 character set,
since my_charset_utf32_general_ci.ctype == NULL.

Solution: convert input to ASCII before parsing,
and use the character set of the returned ASCII string.

      
Problem: After the fix for Bug#12589870, a new field that
stores the length of db name was added in the buffer that
stores the query to be executed. Unlike for the plain user
session, the replication execution did not allocate the
necessary chunk in Query-event constructor. This caused an
invalid read while accessing this field.
      
Solution: We fix this problem by allocating a necessary chunk
in the buffer created in the Query_log_event::Query_log_event()
and store the length of database name.
