Alfranio Correia 7e0da4352c BUG#47678 Changes to n-tables that happen early in a trans. are only flushed upon commit 
Let
    - T be a transactional table and N non-transactional table.
    - B be begin, C commit and R rollback.
    - N be a statement that accesses and changes only N-tables.
    - T be a statement that accesses and changes only T-tables.

In RBR, changes to N-tables that happen early in a transaction are not immediately flushed
upon committing a statement. This behavior may, however, break consistency in the presence
of concurrency since changes done to N-tables become immediately visible to other
connections. To fix this problem, we do the following:

  . B N N T C would log - B N C B N C B T C.
  . B N N T R would log - B N C B N C B T R.

Note that we are not preserving history from the master as we are introducing a commit that
never happened. However, this seems to be more acceptable than the possibility of breaking
consistency in the presence of concurrency.

# Let
# - B be begin, C commit and R rollback.
# - T a statement that accesses and changes only transactional tables, i.e.
# T-tables
# - N a statement that accesses and changes only non-transactional tables,
# i.e, N-tables.
# - M be a mixed statement, i.e. a statement that updates both T- and
# N-tables.
# - M* be a mixed statement that fails while updating either a T
# or N-table.
# - N* be a statement that fails while updating a N-table.
#
# In this test case, when changes are logged as rows either in the RBR or MIXED
# modes, we check if a M* statement that happens early in a transaction is
# written to the binary log outside the boundaries of the transaction and
# wrapped up in a BEGIN/ROLLBACK. This is done to keep the slave consistent with
# the master as the rollback will keep the changes on N-tables and undo them on
# T-tables. In particular, we expect the following behavior:
#
# 1. B M* T C would generate in the binlog B M* R B T C.
# 2. B M M* C would generate in the binlog B M M* C.
# 3. B M* M* T C would generate in the binlog B M* R B M* R B T C.
#
# SBR is not considered in this test because a failing statement is written to
# the binary along with the error code such that a slave executes and rolls it
# back, thus undoing the effects on T-tables.
#
# Note that, in the first case, we are not preserving history from the master as
# we are introducing a rollback that never happened. However, this seems to be
# more acceptable than making the slave diverge. In the second case, the slave
# will diverge as the changes on T-tables that originated from the M statement
# are rolled back on the master but not on the slave. Unfortunately, we cannot
# simply roll the transaction back as this would undo any uncommitted changes
# on T-tables.
#
# We check two more cases. First, INSERT...SELECT* which produces the following
# results:
#
# 1. B T INSERT M...SELECT* C" with an error in INSERT M...SELECT* generates in
# the binlog the following entries: "Nothing".
# 2. B INSERT M...SELECT* C" with an error in INSERT M...SELECT* generates in
# the binlog the following entries: B INSERT M...SELECT* R.
#
# Finally, we also check if any N statement that happens early in a transaction
# (i.e. before any T or M statement) is written to the binary log outside the
# boundaries of the transaction. In particular, we expect the following
# behavior:
#
# 1. B N N T C would generate in the binlog B N C B N C B T C.
# 2. B N N T R would generate in the binlog B N C B N C B T R.
# 3. B N* N* T C would generate in the binlog B N R B N R B T C.
# 4. B N* N* T R would generate in the binlog B N R B N R B T R.
# 5. B N N T N T C would generate in the binlog B N C B N C B T N T C.
# 6. B N N T N T R would generate in the binlog the B N C B N C B T N T R.
#
# Such issues do not happen in SBR. In RBR and MBR, a full-fledged fix will be
# pushed after the WL#2687.
#
# Please, remove this test case after pushing WL#2687.
