[Guilhem wrote] Temporary errors may have filled

thd->net.last_error/errno. For example if there has
466
been a disk full error when writing the row, and it was
467
MyISAM, then thd->net.last_error/errno will be set to
468
"disk full"... and the my_pwrite() will wait until free
469
space appears, and so when it finishes then the
470
write_row() was entirely successful

477
A query which per-row-loop can not be interrupted with
478
KILLED, like INSERT, and that does not invoke stored
479
routines can be binlogged with neglecting the KILLED error.
481
If there was no error (error == zero) until after the end of
482
inserting loop the KILLED flag that appeared later can be
483
disregarded since previously possible invocation of stored
484
routines did not result in any error due to the KILLED. In
485
such case the flag is ignored for constructing binlog event.

Note that we either creating (or opening existing) temporary table or

creating base table on which name we have exclusive lock. So code below

If this is a HEAP table, the automatic DELETE FROM which is written to the

binlog when a HEAP table is opened for the first time since startup, must

not be written: 1) it would be wrong (imagine we're in CREATE SELECT: we

don't want to delete from it) 2) it would be written before the CREATE

For replication, the CREATE-SELECT statement is written
1665
in two pieces: the first transaction messsage contains
1666
the CREATE TABLE statement as a CreateTableStatement message
1667
necessary to create the table.
1669
The second transaction message contains all the InsertStatement
1670
and associated InsertRecords that should go into the table.
1724
For row-based replication, the CREATE-SELECT statement is written
1725
in two pieces: the first one contain the CREATE TABLE statement
1726
necessary to create the table and the second part contain the rows
1727
that should go into the table.
1729
For non-temporary tables, the start of the CREATE-SELECT
1730
implicitly commits the previous transaction, and all events
1731
forming the statement will be stored the transaction cache. At end
1732
of the statement, the entire statement is committed as a
1733
transaction, and all events are written to the binary log.
1735
On the master, the table is locked for the duration of the
1736
statement, but since the CREATE part is replicated as a simple
1737
statement, there is no way to lock the table for accesses on the
1738
slave. Hence, we have to hold on to the CREATE part of the
1739
statement until the statement has finished.

Note 1: In RBR mode, we generate a CREATE TABLE statement for the
1843
created table by calling store_create_info() (behaves as SHOW
1844
CREATE TABLE). In the event of an error, nothing should be
1845
written to the binary log, even if the table is non-transactional;
1846
therefore we pretend that the generated CREATE TABLE statement is
1847
for a transactional table. The event will then be put in the
1848
transaction cache, and any subsequent events (e.g., table-map
1849
events and binrow events) will also be put there. We can then use
1850
ha_autocommit_or_rollback() to either throw away the entire
1851
kaboodle of events, or write them to the binary log.
1853
We write the CREATE TABLE statement here and not in prepare()
1854
since there potentially are sub-selects or accesses to information
1855
schema that will do a close_thread_tables(), destroying the
1856
statement transaction cache.
