WL#6161 Integrating with InnoDB codebase in MySQL 5.5

      
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

  dict0mem.c:(.text+0xa4e): undefined reference to `innobase_casedn_str'
  collect2: ld returned 1 exit status
  make[2]: *** [mysqlbackup] Error 1

  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

  # include "sync0rw.h" is excluded from hotbackup compilation in dict0dict.h

  This causes extern rw_lock_t*	btr_search_latch_temp; to throw a failure because
  the definition of rw_lock_t is not found.
@ storage/innobase/include/buf0buf.h
  Excluding buffer pool functions that are unused from the
  MEB codebase.
@ storage/innobase/include/buf0buf.ic
  replicated the exclusion of

  #include "buf0flu.h"
  #include "buf0lru.h"
  #include "buf0rea.h"

  by looking at the current codebase in <meb-trunk>/src/innodb
  @ storage/innobase/include/dict0dict.h
  dict_table_x_lock_indexes, dict_table_x_unlock_indexes, dict_table_is_corrupted,
  dict_index_is_corrupted, buf_block_buf_fix_inc_func are unused in MEB and was
  leading to compilation errors and hence excluded.
@ storage/innobase/include/dict0dict.ic
  dict_table_x_lock_indexes, dict_table_x_unlock_indexes, dict_table_is_corrupted,
  dict_index_is_corrupted, buf_block_buf_fix_inc_func are unused in MEB and was
  leading to compilation errors and hence excluded.
@ storage/innobase/include/log0log.h

  mutex_t definitions were excluded as seen from ambient code
  hence excluding definition for log_flush_order_mutex also.
@ storage/innobase/include/os0file.h
  Bug in InnoDB code, create_mode should have been create.
@ storage/innobase/include/srv0srv.h
  In file included from /home/narayanan/mysql-server/mysql-5.5-meb-rel3.8-innodb-integration-1/storage/innobase/buf/buf0buf.c:50:0:

  srv_use_native_aio - we do not use native aio of the OS anyway from MEB. MEB does not compile
  InnoDB with this option. Hence disabling it.
@ storage/innobase/include/trx0sys.h

  unused calls excluded to enable compilation
@ storage/innobase/mem/mem0dbg.c
    excluding #include "ha_prototypes.h" that lead to definitions in ha_innodb.cc
@ storage/innobase/os/os0file.c
    InnoDB not compiled with aio support from MEB anyway. Hence excluding this from
    the compilation.
@ storage/innobase/page/page0zip.c
  page0zip.c:(.text+0x4e9e): undefined reference to `buf_pool_from_block'
  collect2: ld returned 1 exit status

  buf_pool_from_block defined in buf0buf.ic, most of the file is excluded for compilation of MEB
@ storage/innobase/ut/ut0dbg.c
  excluding #include "ha_prototypes.h" since it leads to definitions in ha_innodb.cc
  innobase_basename(file) is defined in ha_innodb.cc. Hence excluding that also.
@ storage/innobase/ut/ut0ut.c
  cal_tm unused from MEB, was leading to earnings, hence disabling for MEB.
