unknown bcb3170c97 Bug #34283 mysqlbinlog leaves tmpfile after termination if binlog contains load data infile
With statement- or mixed-mode logging, "LOAD DATA INFILE" queries
are written to the binlog using special types of log events.
When mysqlbinlog reads such events, it re-creates the file in a
temporary directory with a generated filename and outputs a
"LOAD DATA INFILE" query where the filename is replaced by the
generated file. The temporary file is not deleted by mysqlbinlog
after termination.

To fix the problem, in mixed mode we go to row-based. In SBR, we
document it to remind user the tmpfile is left in a temporary
directory.

# ==== Purpose ====
#
# check replication of load data with the server parameters subjected to
# read_buffer_size > max_allowed_packet
#
# ==== Implementation ====
#
# Insert many rows into t1, write t1 to file.
# Load the file into t2.
# See that t2 came out as expected on slave.
