from log):
When row-based logging is used, the CREATE-SELECT is written as two
parts: as a CREATE TABLE statement and as the rows for the table. For
both transactional and non-transactional tables, the CREATE TABLE
statement was written to the transaction cache, as were the rows, and
on statement end, the entire transaction cache was written to the binary
log if the table was non-transactional. For transactional tables, the
events were kept in the transaction cache until end of transaction (or
statement that were not part of a transaction).
For the case when AUTOCOMMIT=0 and we are creating a transactional table
using a create select, we would then keep the CREATE TABLE statement and
the rows for the CREATE-SELECT, while executing the following statements.
On a rollback, the transaction cache would then be cleared, which would
also remove the CREATE TABLE statement. Hence no table would be created
on the slave, while there is an empty table on the master.
This relates to BUG#22865 where the table being created exists on the
master, but not on the slave during insertion of rows into the newly
created table. This occurs since the CREATE TABLE statement were still
in the transaction cache until the statement finished executing, and
possibly longer if the table was transactional.
This patch changes the behaviour of the CREATE-SELECT statement by
adding an implicit commit at the end of the statement when creating
non-temporary tables. Hence, non-temporary tables will be written to the
binary log on completion, and in the even of AUTOCOMMIT=0, a new
transaction will be started. Temporary tables do not commit an ongoing
transaction: neither as a pre- not a post-commit.
The events for both transactional and non-transactional tables are
saved in the transaction cache, and written to the binary log at end
of the statement.
mysql-test/r/rpl_row_create_table.result:
Result change
mysql-test/t/rpl_row_create_table.test:
Requring InnoDB for slave as well.
Adding test CREATE-SELECT that is rolled back explicitly.
Changing binlog positions.
sql/log.cc:
Adding helper class to handle lock/unlock of mutexes using RAII.
Factoring out code into write_cache() function to transaction cache
to binary log.
Adding function THD::binlog_flush_transaction_cache() to flush the
transaction cache to the binary log file.
Factoring out code into binlog_set_stmt_begin() to set the beginning
of statement savepoint.
Clearing before statement point when transaction cache is truncated
so that these points are out of range.
sql/log.h:
Adding method MYSQL_BIN_LOG::write_cache()
sql/log_event.h:
Replicating OPTION_NOT_AUTOCOMMIT flag (see changeset comment)
sql/mysql_priv.h:
Although left-shifting signed integer values is well-defined,
it has potential for strange errors. Using unsigned long long
instead of signed long long since this is the type of the options
flags.
sql/slave.cc:
Adding printout of transaction-critical thread flags.
sql/sql_class.h:
Adding function THD::binlog_flush_transaction_cache()
Adding function THD::binlog_set_stmt_begin()
sql/sql_insert.cc:
Adding code to cache events for a CREATE-SELECT statement.
Disabling binlog for SBR (but not RBR) when sending error for select part
of CREATE-SELECT statement.
Adding implicit commit at end of statement for non-temporary tables.
