  The problem: table_open_method is not calculated properly if '*' is used in 'select'
  The fix: added table_open_method calculation for such case

                  
The code to get read the value of a system variable was extracting its value 
on PREPARE stage and was substituting the value (as a constant) into the parse tree.
Note that this must be a reversible transformation, i.e. it must be reversed before
each re-execution.
Unfortunately this cannot be reliably done using the current code, because there are
other non-reversible source tree transformations that can interfere with this
reversible transformation.
Fixed by not resolving the value at PREPARE, but at EXECUTE (as the rest of the 
functions operate). Added a cache of the value (so that it's constant throughout
the execution of the query). Note that the cache also caches NULL values.
Updated an obsolete related test suite (variables-big) and the code to test the 
result type of system variables (as per bug 74).

ha_statistic_increment for rpl_temporary

Problem: in some cases master send a special event to reconnecting
slave to keep slave's temporary tables (see #17284) and they still 
have references to the "old" SQL slave thread and use them to access
thread's data.

Fix: set temporary tables thread references to the actual SQL slave
thread in such cases.

warnings)

Before this fix, several places in the code would raise a warning with an
error code 0, making it impossible for a stored procedure, a connector,
or a client application to trigger logic to handle the warning.
Also, the warning text was hard coded, and therefore not translated.

With this fix, new errors numbers have been created to represent these
warnings, and the warning text is coded in the errmsg.txt file.

so that if the substitution contains single-quotes, the program will fail.

"Trigger fired multiple times leads to gaps in auto_increment sequence".
The bug was that if a trigger fired multiple times inside a top
statement (for example top-statement is a multi-row INSERT,
and trigger is ON INSERT), and that trigger inserted into an auto_increment
column, then gaps could be observed in the auto_increment sequence,
even if there were no other users of the database (no concurrency).
It was wrong usage of THD::auto_inc_intervals_in_cur_stmt_for_binlog.
Note that the fix changes "class handler", I'll tell the Storage Engine API team.

  result; before the bugfix, the sequence was 1,2,4,6,8,10,12...
mysql-test/t/trigger-trans.test:
  test for BUG#31612
sql/handler.cc:
  See revision comment of handler.h.
  As THD::auto_inc_intervals_in_cur_stmt_for_binlog is cumulative
  over all trigger invokations by the top statement, the
  second invokation of the trigger arrived in handler::update_auto_increment()
  with already one interval in
  THD::auto_inc_intervals_in_cur_stmt_for_binlog. The method thus
  believed it had already reserved one interval for that invokation,
  thus reserved a twice larger interval (heuristic when we don't know
  how large the interval should be: we grow by powers of two). InnoDB
  thus increased its internal per-table auto_increment counter by 2
  while only one row was to be inserted. Hence a gap in the sequence.
  The fix is to use the new handler::auto_inc_intervals_count.
  Note that the trigger's statement knows how many rows it is going
  to insert, but provides estimation_rows_to_insert == 0 (see comments
  in sql_insert.cc why triggers don't call handler::ha_start_bulk_insert()).
  * removing white space at end of line
  * we don't need to maintain THD::auto_inc_intervals_in_cur_stmt_for_binlog
  if no binlogging or if row-based binlogging. Using auto_inc_intervals_count in
  the heuristic makes the heuristic independent of binary logging, which is good.
sql/handler.h:
  THD::auto_inc_intervals_in_cur_stmt_for_binlog served
   - for binlogging
   - as a heuristic when we have no estimation of how many records the
     statement will insert.
  But the first goal needs to be cumulative over all statements which
  form a binlog event, while the second one needs to be attached to each
  statement. THD::auto_inc_intervals_in_cur_stmt_for_binlog is cumulative,
  leading to BUG#31612. So we introduce handler::auto_inc_intervals_count
  for the second goal. See the revision comment of handler.cc.
  A smaller issue was that, even when the binlog event was only one
  statement (no triggers, no stored functions),
  THD::auto_inc_intervals_in_cur_stmt.nb_elements() could be lower than
  the number of reserved intervals (fooling the heuristic), because its
  append() method collapses two contiguous intervals in one.
  Note that as auto_inc_intervals_count is in class 'handler' and not
  in class 'THD', it does not need to be handled in
  THD::reset|restore_sub_statement_state().
sql/log.cc:
  Comment is wrong: if auto_increment is second, in handler::update_auto_increment()
  'append' is false and so auto_inc_intervals_in_cur_stmt_for_binlog
  is empty, we do not come here.

That causes problems for partition engine when some partitions have records some not
as the engine uses same access method for all partitions.

Now partition engine doesn't call index_first/index_last
for empty tables.

    problems are located in the sql_partition.cc where functions calculation
    partition_id don't expect error returned from item->val_int().
    Fixed by adding checks to these functions.
    Note  - it tries to fix more problems than just the reported bug.
