"load data" statements were written to the binlog as a mix of the original statement and bits recreated from parse-info. This relied on implementation details and broke with IGNORE_SPACES and versioned comments. We now completely resynthesize the query for LOAD DATA for binlog (which among other things normalizes them somewhat with regard to case, spaces, etc.). We have already parsed the query properly, so we make use of that rather than mix-and-match string literals and parsed items. This should make us safe with regard to versioned comments, even those spanning multiple tokens. Also no longer affected by IGNORE_SPACES. mysql-test/r/mysqlbinlog.result: LOAD DATA INFILE normalized mysql-test/suite/binlog/r/binlog_killed_simulate.result: LOAD DATA INFILE normalized mysql-test/suite/binlog/r/binlog_row_mix_innodb_myisam.result: LOAD DATA INFILE normalized mysql-test/suite/binlog/r/binlog_stm_blackhole.result: LOAD DATA INFILE normalized mysql-test/suite/binlog/r/binlog_stm_mix_innodb_myisam.result: LOAD DATA INFILE normalized mysql-test/suite/rpl/r/rpl_innodb_mixed_dml.result: LOAD DATA INFILE normalized mysql-test/suite/rpl/r/rpl_loaddata.result: LOAD DATA INFILE normalized mysql-test/suite/rpl/r/rpl_loaddata_fatal.result: LOAD DATA INFILE normalized; offsets adjusted to reflect that mysql-test/suite/rpl/r/rpl_loaddata_map.result: LOAD DATA INFILE normalized mysql-test/suite/rpl/r/rpl_loaddatalocal.result: test for #43746 - trying to break LOAD DATA part of parser mysql-test/suite/rpl/r/rpl_stm_log.result: LOAD DATA INFILE normalized mysql-test/suite/rpl/t/rpl_loaddatalocal.test: try to break the LOAD DATA part of the parser (test for #43746) mysql-test/t/mysqlbinlog.test: LOAD DATA INFILE normalized; adjust offsets to reflect that sql/log_event.cc: clean up Load_log_event::print_query and friends so they don't print excess spaces. add support for printing charset names to print_query. sql/log_event.h: We already have three places where we synthesize LOAD DATA queries. Better use one of those! sql/sql_lex.h: When binlogging LOAD DATA statements, we make up the statement to be logged (from the parse-info, rather than substrings of the original query) now. Consequently, we no longer need (string-) pointers into the original query. sql/sql_load.cc: Completely rewrote write_execute_load_query_log_event() to synthesize the LOAD DATA statement wholesale, rather than piece it together from synthesized bits and literal excerpts from the original query. This will not only give us a nice, normalized statement (all uppercase, no excess spaces, etc.), it will also handle comments, including versioned comments right, which is certainly more than we can say about the previous incarnation. sql/sql_yacc.yy: We're no longer assembling LOAD DATA statements from bodyparts of the original query, so some bookkeeping in the parser can go.
