- Introduce a class FTSQueryRunner to handle queries for fulltext
internal tables. Basically it creates a query, prepares the
fulltext internal table for read or write process. Build a tuple
based on the given table and assign the FTS_CONFIG, FTS_COMMON_TABLES
and FTS_AUX_TABLE fields based on the given value. This class
also handles INSERT, DELETE, REPLACE, UPDATE and
execute the function for each record (record_executor).
FTSQueryRunner::create_query_thread(): Create a query thread to execute
the statement on internal FULLTEXT tables
FTSQueryRunner::build_tuple(): Build a tuple for the operation
FTSQueryRunner::build_clust_ref(): Build a clustered index reference
for clustered index lookup for the secondary index record
FTSQueryRunner::assign_config_fields(): Assign the tuple for the
FTS CONFIG internal table
FTSQueryRunner::assign_common_table_fields(): Assign the tuple for
FTS_DELETED, FTS_DELETED_CACHE, FTS_BEGIN_DELETED,
FTS_BEGIN_DELETED_CACHE common tables
FTSQueryRunner::assign_aux_table_fields(): Assign the tuple for
FTS_PREFIX_INDEX tables.
FTSQueryRunner::handle_error(): Handling error for DB_LOCK_WAIT,
retry the operation
FTSQueryRunner::open_table(): Open the table based on the fulltext
auxiliary table name and FTS common table name
FTSQueryRunner::prepare_for_write(): Lock the table for write
process by taking Intention Exclusive lock
FTSQueryRunner::prepare_for_read(): Lock the table for read
process by taking Intention Shared lock
FTSQueryRunner::write_record(): Insert the tuple into the given table
FTSQueryRunner::lock_or_sees_rec(): Lock the record in case of
DELETE, SELECT_UPDATE operation. Fetch the correct version of record in
case of READ operation. It also does clustered index lookup in case
of search is on secondary index
fts_cmp_rec_dtuple_prefix(): Compare the record with given tuple field
for tuple field length
FTSQueryRunner::record_executor(): Read the record of the given index and
do call the callback function for each record
FTSQueryRunner::build_update_config(): Build the update vector for
FULLTEXT CONFIG table
FTSQueryRunner::update_record(): Update the record with update vector
exist in FTSQueryRunner
Removed the fts_parse_sql(), fts_eval_sql(), fts_get_select_columns_str()
and fts_get_docs_clear().
Moved fts_get_table_id() & fts_get_table_name() from fts0sql.cc to
fts0fts.cc and deleted the file fts0sql.cc
Removed ins_graph, sel_graph from fts_index_cache_t
Changed the callback function default read function parameter for
each clustered index record to
bool fts_sql_callback(dict_index_t*, const rec_t *, const rec_offs*,
void *);
Following parameters are changed to default read function parameter:
fts_read_stopword()
fts_fetch_store_doc_id()
fts_query_expansion_fetch_doc()
fts_read_count()
fts_get_rows_count()
fts_init_doc_id()
fts_init_recover_doc()
read_fts_config()
fts_optimize_read_node()
fts_optimize_index_fetch_node()
fts_index_fetch_nodes()
fts_fetch_index_words()
fts_index_fetch_words()
fts_fetch_doc_ids()
fts_table_fetch_doc_ids()
fts_read_ulint()
fts_copy_doc_ids()
fts_optimize_create_deleted_doc_id_snapshot()
fts_query_index_fetch_nodes()
fts_query_fetch_document()
fts_query_index_fetch_nodes()
row_upd_clust_rec_low(): Function does updates a clustered
index record of a row when ordering fields don't change.
Function doesn't have dependency on row_prebuilt_t. This can be
used by fulltext internal table update operation
Row_sel_get_clust_rec_for_mysql::operator(): Removed the
parameter row_prebuilt_t and caller does pass the prebuilt
related variables
Removed the parser usage and execute the query directly on
fulltext internal tables in the following function:
fts_read_stopword()
fts_fetch_store_doc_id()
fts_query_expansion_fetch_doc()
fts_read_count()
fts_get_rows_count()
fts_init_doc_id()
fts_init_recover_doc()
read_fts_config()
fts_optimize_read_node()
fts_optimize_index_fetch_node()
fts_index_fetch_nodes()
fts_fetch_index_words()
fts_index_fetch_words()
fts_fetch_doc_ids()
fts_table_fetch_doc_ids()
fts_read_ulint()
fts_copy_doc_ids()
fts_optimize_create_deleted_doc_id_snapshot()
fts_query_index_fetch_nodes()
fts_query_fetch_document()
fts_query_index_fetch_nodes()
i_s_fts_deleted_generic_fill()
i_s_fts_index_table_fill_selected()
