unknown 38005eae6a WL#2575 - Fulltext: Parser plugin for FTS
Manual merge.


Makefile.am:
  Added new 'plugin' subdir.
configure.in:
  Added plugin related makefiles.
include/my_base.h:
  Added HA_OPEN_FROM_SQL_LAYER flag - indicates that a table was openned from the sql layer.
  Added HA_OPTION_RELIES_ON_SQL_LAYER flag - indicates that a table relies on the sql layer.
  Added HA_CREATE_RELIES_ON_SQL_LAYER flag - indicates that a table must be created with
  HA_OPTION_RELIES_ON_SQL_LAYER flag.
include/myisam.h:
  Distinct fulltext parser number added.
include/plugin.h:
  Revise comment.
sql/ha_myisam.cc:
  Pass HA_OPEN_FROM_SQL_LAYER flag to mi_open().
  Pass HA_CREATE_RELIES_ON_SQL_LAYER flag to mi_create().
sql/sql_plugin.cc:
  Reuse "unused" dynamic array elements.
  A check for plugin info interface version.
sql/sql_plugin.h:
  Added plugin_type_names[] - string plugin type names.
sql/sql_show.cc:
  Use plugin_type_names array instead of switch to find literal parser name representation.
sql/sql_table.cc:
  Fixed that ALTER TABLE ... ADD INDEX loses WITH PARSER info.
storage/myisam/ft_boolean_search.c:
  Call fulltext parser init() function, pass MYSQL_FTPARSER_PARAM, returned by
  ftparser_call_initializer(), to parser->parse().
storage/myisam/ft_nlq_search.c:
  Call fulltext parser init() function, pass MYSQL_FTPARSER_PARAM, returned by
  ftparser_call_initializer(), to parser->parse().
storage/myisam/ft_parser.c:
  Added two functions:
  ftparser_call_initializer() - calls parser->init() function if specified and parser is not yet
  initialized. Returns MYSQL_FTPARSER_PARAM *.
  ftparser_call_deinitializer() - calls parser->deinit() function if specified and parser was
  initialized. Deinitializes all parsers.
  ft_parse() accepts additional param now - MYSQL_FTPARSER_PARM and passes it to parser->parse().
storage/myisam/ft_update.c:
  Call fulltext parser init() function, pass MYSQL_FTPARSER_PARAM, returned by
  ftparser_call_initializer(), to _mi_ft_parse().
  _mi_ft_parse() accepts additional param now - MYSQL_FTPARSER_PARAM and passes
  it to parser->parse().
storage/myisam/ftdefs.h:
  Prototypes for new functions were added. MYSQL_FTPARSER_PARAM was added
  to ft_parse and _mi_ft_parse().
storage/myisam/mi_close.c:
  Free ftparser_param allocated by ftparser_call_initializer().
storage/myisam/mi_create.c:
  If a table relies on the sql layer, set HA_OPTION_RELIES_ON_SQL_LAYER.
storage/myisam/mi_locking.c:
  Call deinitializer for each initialized parser.
storage/myisam/mi_open.c:
  Set default values for share->ftparser and keydef->ftparser_nr.
  If a table is openned from the non-sql layer and HA_OPTION_RELIES_ON_SQL_LAYER is set, raise
  HA_ERR_UNSUPPORTED error.
storage/myisam/myisamdef.h:
  Added number of distinct parsers to MYISAM_SHARE.
  Added ftparser_param to MI_INFO.
plugin/Makefile.am:
  New BitKeeper file ``plugin/Makefile.am''
plugin/fulltext/Makefile.am:
  New BitKeeper file ``plugin/fulltext/Makefile.am''
plugin/fulltext/plugin_example.c:
  New BitKeeper file ``plugin/fulltext/plugin_example.c''
