* Added version of lex_string_eq that compares with const char *Monty2018-04-301-4/+10
| | | | | | | | Change all my_stcasecmp() calls that uses lexical keywords to use lex_string_eq. This is faster as we only call strcasecmp() for strings of different lengths. Removed not used function lex_string_syseq()
* cleanup: remove XString::operator== and !=Sergei Golubchik2018-04-101-0/+9
| | | | use named methods instead.
* change lex_string_eq to return what it saysSergei Golubchik2018-04-101-8/+6
| | | | | the function xxx_eq(a,b) returns true if two elements are equal and false if they are not.
* Changed database, tablename and alias to be LEX_CSTRINGMonty2018-01-301-0/+52
This was done in, among other things: - thd->db and thd->db_length - TABLE_LIST tablename, db, alias and schema_name - Audit plugin database name - lex->db - All db and table names in Alter_table_ctx - st_select_lex db Other things: - Changed a lot of functions to take const LEX_CSTRING* as argument for db, table_name and alias. See init_one_table() as an example. - Changed some function arguments from LEX_CSTRING to const LEX_CSTRING - Changed some lists from LEX_STRING to LEX_CSTRING - threads_mysql.result changed because process list_db wasn't always correctly updated - New append_identifier() function that takes LEX_CSTRING* as arguments - Added new element tmp_buff to Alter_table_ctx to separate temp name handling from temporary space - Ensure we store the length after my_casedn_str() of table/db names - Removed not used version of rename_table_in_stat_tables() - Changed Natural_join_column::table_name and db_name() to never return NULL (used for print) - thd->get_db() now returns db as a printable string (thd->db.str or "")
