519. By Laurynas Biveinis on 2013-01-22

Implement user requests for the XtraDB changed page bitmaps.


Server changes:
- sql/lex.h: new lexical symbol CHANGED_PAGE_BITMAPS_SYM.

- sql/sql_yacc.yy: new lexical symbol CHANGED_PAGE_BITMAPS_SYM. Add
  "CHANGED_PAGE_BITMAPS" syntax options for FLUSH and RESET,
  "CHANGED_PAGE_BITMAPS BEFORE <ulonglong value>" for PURGE.

- sql/sql_parse.cc: extend SQLCOM_PURGE handling with lex->type ==
  and REFRESH_RESET_PAGE_BITMAPS in reload_acl_and_cache().

- include/mysql_com.h: define two new options,

- include/mysql_com.h Define PURGE command option

- sql/handler.h: new handlerton function pointers
  flush_changed_page_bitmaps and purge_changed_page_bitmaps. New

- sql/handler.cc: new functions flush_changed_page_bitmaps_handlerton,

XtraDB changes:
- handler/ha_innodb.cc: new functions

- include/log0online.h: new function
  log_online_purge_changed_page_bitmap. In function declarations
  replace all empty parameter lists with void.

- include/sync0sync.h: new latching order level SYNC_LOG_ONLINE.

- log/log0online.c: add mutex field to log_bitmap_struct. Create it
  at log_online_read_init, destroy at
  log_online_read_shutdown. To serialize the user requests with
  asynchronous processing, acquire it at log_online_follow_redo_log.
  Assert that it is taken at the following functions that may be
  called only during online tracking: log_online_parse_redo_log,
  log_online_add_to_parse_buf, log_online_parse_redo_log_block,
  log_online_follow_log_seg, log_online_follow_log_group,
  log_online_write_bitmap_page, log_online_write_bitmap.
  New function log_online_purge_changed_page_bitmaps.
  In log_online_read_init replace ut_a with compile_time_assert.

Test suite changes:
- New test case percona_changed_page_bmp_requests.

- Replace include/delete_innodb_bitmaps.inc by FLUSH/RESET invocation
  in other changed page bitmap test cases.
