  update result

Here is the scenario that causes the failure.(by Mats)

1. The to-be corrupt log event (let's call it X), is split into two
   packets B and C on the network level (net_write_buff()). The parts
   are X = (x',x''). The part x' ends up in packet B and part x''
   ends up in packet C. Prior to the corrupt event X, the event Y has
   been written successfully, but has been split into two packets as
   well, which we call (y',y'').
2. The master sends packet A = (y'',x') to the slave, increases the
   packet sequence number, the slave receives the packet, but fails
   to reply before the master gets a timeout.
3. Since the master got a timeout, it reports failure, and aborts
   sending the binary log by exiting mysql_binlog_send(). However, it
   leaves the buffer intact, still holding y'' (but not x', since the
   write_pos is not increased).
4. After exiting mysql_binlog_send(), the master does a
   disconnection of the client thread, which involves sending an
   error message e to the client (i.e., the slave).
5. In this case, net_write_buff() is used again, but this time the
   old contents of the packet is used so that the new packet is
   D = (y'',e). Note that this will use a new packet sequence number,
   since the packet number was increased in step 2.
6. The slave receives the tail y'' of the Y log event, concatenates
   this with x' (which it already received), and writes the event
   (x',y'') it to the relay log since it hasn't noticed anything is
   amiss.
7. It then tries to read more bytes, which is either e (if the length
   given for X just happened to match the length given for Y, or just
   plain garbage because the slave is out of sync with what is
   actually sent.
8. After a while, the SQL thread tries to execute the event (x',y''),
   which is very likely to be just nonsense.

The problem can be fixed by not resetting net->error after the call of 
mysql_binlog_send, so the error message will not be sent and the connection
will be closed.


sql/sql_parse.cc:
  Do not reset net->error, if net->error == 2, we should not try to use the connection again

The problem is when create/rename/drop users, the statement was logged regardless of error, even if no data has been changed, the statement was logged.

After this patch, create/rename/drop users don't write the binlog if the statement makes no changes, if the statement does make any changes, log the statement with possible error code.

This patch is based on the patch for BUG#29749, which is not pushed

          read_buffer_size set on master
BUG#33413 show binlog events fails if binlog has event size of close
          to max_allowed_packet


The size of Append_block replication event was determined solely by
read_buffer_size whereas the rest of replication code deals with
max_allowed_packet.
When the former parameter was set to larger than the latter there were
two artifacts: the master could not read events from binlog;
show master events did not show.

Fixed with 
- fragmenting the used io-cached buffer into pieces each size of less
  than max_allowed_packet (bug#30435)
- incrementing show-binlog-events handling thread's max_allowed_packet
  with the max estimated for the replication header size

Complementary patch since LOAD DATA INFILE was not covered in
the previous patch.

This patch adds a check so that the slave skip counter is not
decreased to zero if seeing a BEGIN_LOAD_QUERY_EVENT,
APPEND_BLOCK_EVENT, or CREATE_FILE_EVENT since these cannot
end a group. The group is terminated by an EXECUTE_LOAD_QUERY_
EVENT or DELETE_FILE_EVENT.

The reason of this bug is that when mysqlbinlog dumps a query, the query is written to
output with a delimeter appended right after it, if the query string ends with a '--'
comment, then the delimeter would be considered as part of the comment, if there are any
statements after this query, then it will cause a syntax error.

When executing drop view statement on the master, the statement is written
into bin-log without checking for possible errors, so the statement would 
always be bin-logged with error code cleared even if some error might occur, 
for example, some of the views being dropped does not exist. This would cause 
failure on the slave.

Writing bin-log after check for errors, if at least one view has been dropped
the query is bin-logged possible with an error.

When running mysqlbinlog on a 64-bit machine with a corrupt relay log,
it causes mysqlbinlog to crash. In this case, the crash is caused
because a request for 18446744073709534806U bytes is issued, which
apparantly can be served on a 64-bit machine (speculatively, I assume)
but this causes the memcpy() issued later to copy the data to segfault.

The request for the number of bytes is caused by a computation
of data_len - server_vars_len where server_vars_len is corrupt in such
a sense that it is > data_len. This causes a wrap-around, with the
the data_len given above.

This patch adds a check that if server_vars_len is greater than
data_len before the substraction, and aborts reading the event in
that case marking the event as invalid. It also adds checks to see
that reading the server variables does not go outside the bounds
of the available space, giving a limited amount of integrity check.

  log_event so that the variable can really be read. Abort reading
  and mark the event as invalid otherwise.
