The source of the problem was in my_vsnprintf() implementation.


strings/my_vsnprintf.c:
  Fixing a problem in vsnprintf('%.*s', len, ptr)
  When processing the above format, it's incorrect
  to use strlen() because the string is not necessarily
  a null terminated string.
  Changing strlen() followed by set_if_smaller()
  to strnlen() - which covers both cases - limiting
  by '\0' and by "len".

The bug in that slave version of a table with unique field still was
able to execute INSERT query as replace whereas it's impossible on master.

The reason of this artifact is wrong usage of ndb->extra:s.

Fixed with resetting flags at do_after.
There is open issue with symmetrical resetting
   table->file->extra(HA_EXTRA_NO_IGNORE_NO_KEY)
which i had to hand to bug#27077.
The test for the current bug was committed in a cset for bug#27320.


sql/log_event.cc:
  fixing do_after_row_operation to reset the effect of the extra engine's 
  flags set at do_before;
  comments on meaning of extra flags added;
  execution of table->file->ha_end_bulk_insert() in do_after is not dependant on error;

  
Refining the tests since pb revealed the older version's fragality - the error from SF() due to killed
may be different on different env:s.
DBUG_ASSERT instead of assert.

The reason for the bug was that replaying of a query on slave could not be possible since its event
was recorded with the killed error. Due to the specific of handling INSERT, which per-row-while-loop is 
unbreakable to killing, the query on transactional table should have not appeared in binlog unless
there was  a call to a stored routine that got interrupted with killing (and then there must be an error
returned out of the loop).
   
The offered solution added the following rule for binlogging of INSERT that accounts the above
specifics:
For INSERT on transactional-table if the error was not set the only raised flag
is harmless and is ignored via masking out on time of creation of binlog event.
   
For both table types the combination of raised error and KILLED flag indicates that there
was potentially partial execution on master and consistency is under the question.
In that case the code continues to binlog an event with an appropriate killed error.
 
The fix relies on the specified behaviour of stored routine that must propagate the error 
to the top level query handling if the thd->killed flag was raised in the routine execution.
   
The patch adds an arg with the default killed-status-unset value to Query_log_event::Query_log_event.


sql/log_event.cc:
  killed_status as the value of thd->killed can be passed as an arg to the constructor.
  if the value is different from the default the arg is set to the current thd->killed value.
  A caller might need to masquerade thd->killed with THD::NOT_KILLED.
  So far only mysql_insert() uses such explicit way to tell the constructor about killing status.
sql/log_event.h:
  default arg to the constructor with meaning of killed status of the query. 
  if the arg is not explicitly provided the status of thd->killed will be snapshot 
  inside of the constuctor, which is potentially incorrect (see bug#27571)
sql/sql_class.h:
  extending killed_state with no-state member.
sql/sql_insert.cc:
  ignore the KILLED flag incl KILL_BAD_DATA when the INSERT query event 
  is created without an `error';
sql/sql_update.cc:
  Suggestion how to fix bug#27571 as comments.

As MySQL character set tests can print results in many character sets
(latin1, utf8-8, sjis, cp932 and others) - its output can be incompatible
with the current locale settings, which makes PERL confuse.

Fix: reset LC_ALL and LC_CTYPE to "C", which is compatible with
any character set.


mysql-test/mysql-test-run.pl:
  Ignore current locale settings, because "mysqltest" output
  can be not compatible with the locale.

Problem: Memory overrun happened in attempts to generate
error messages (e.g. in case of incorrect XPath syntax).
Reason: set_if_bigger() was used instead of set_if_smaller().

and making minor additional code clean-ups.

    using '%.*s' instead if '%s' in the error format.
