When using mixed mode the record values stored inside the storage
engine differed from the ones computed from the row event. This
happened because the prepare_record function was calling
empty_record macro causing some don't care bits to be left set.
Replacing the empty_record plus explicitly setting defaults with
restore_record to restore the record default values fixes this.

# BUG#39753: Replication failure on MIXED + bit + myisam + no PK
|
|
#
|
|
# Description
|
|
# -----------
|
|
# Simple statements against a bit column cause failure in mixed-mode
|
|
# replication.
|
|
#
|
|
# Implementation is as follows:
|
|
# i) A table with two bit fields is created. One of them is a key.
|
|
# ii) A record is inserted without specifying the key value.
|
|
# iii) The record is deleted using a where clause that matches it.
|
|
# iv) repeat i-iii) for bit key that has different size, generating
|
|
# different extra bits values
|
|
# v) The slave is synchronized with master
|
|
# vi) The table is dropped on master and the slave is re-synchronized
|
|
# with master.
|
|
#
|
|
# Step v) made the bug evident before the patch, as the slave would
|
|
# fail to find the correspondent row in its database (although it did
|
|
# the insert in step ii) ).
|
|
#
|
|
# Obs
|
|
# ---
|
|
# This test is based on the "how to repeat" section from the bug report.
