The problem was a race condition in a test case.

The fix eliminates the race condition by explicit
wait on UNIX socket to start accepting connections.

The patch affects only test suite (i.e. does not touch
server codebase).

Non-upper-level INSERTs (the ones in the body of stored procedure,
stored function, or trigger) into a table that have AUTO_INCREMENT
column didn't affected the result of LAST_INSERT_ID() on this level.

The problem was introduced with the fix of bug 6880, which in turn was
introduced with the fix of bug 3117, where current insert_id value was
remembered on the first call to LAST_INSERT_ID() (bug 3117) and was
returned from that function until it was reset before the next
_upper-level_ statement (bug 6880).

The fix for bug#21726 brings back the behaviour of version 4.0, and
implements the following: remember insert_id value at the beginning
of the statement or expression (which at that point equals to
the first insert_id value generated by the previous statement), and
return that remembered value from LAST_INSERT_ID() or @@LAST_INSERT_ID.

Thus, the value returned by LAST_INSERT_ID() is not affected by values
generated by current statement, nor by LAST_INSERT_ID(expr) calls in
this statement.

Version 5.1 does not have this bug (it was fixed by WL 3146).

  previous statement, and return this value for @@LAST_INSERT_ID.
sql/sql_class.cc:
  Reset THD::last_insert_id_used after each statement execution.
sql/sql_class.h:
  Rather then remember current insert_id value on first invocation of
  THD::insert_id(), remember it in Item_func_last_insert_id::fix_fields(),
  sys_var_last_insert_id::value_ptr(), or mysql_execute_command().
  Remove THD::insert_id(), as it lost its value now.
sql/sql_insert.cc:
  THD::insert_id() is removed, use THD::last_insert_id directly.
sql/sql_load.cc:
  THD::insert_id() is removed, using THD::last_insert_id directly is OK.
sql/sql_parse.cc:
  Remember in THD::current_insert_id first generated insert id value of

  No need to reset THD::last_insert_id_used in
  mysql_reset_thd_for_next_command(), it will be reset after each
  statement.
sql/sql_select.cc:
  If "IS NULL" is replaced with "= <LAST_INSERT_ID>", use right value,
  which is THD::current_insert_id, and also set THD::last_insert_id_used

On an INSERT into an updatable but non-insertable view an error message was
issued stating the view being not updatable. This can lead to a confusion of a
user.

A new error message is introduced. Is is showed when a user tries to insert
into a non-insertable view.

create_tmp_table()".

The fix for bug 21787 "COUNT(*) + ORDER BY + LIMIT returns wrong
result" introduced valgrind warnings which occured during execution
of information_schema.test and sp-prelocking.test in version 5.0.
There were no user visible effects.

The latter fix made create_tmp_table() dependant on
THD::lex::current_select value. Valgrind warnings occured when this
function was executed and THD::lex::current_select member pointed
to uninitialized SELECT_LEX instance.

This fix tries to remove this dependancy by moving some logic
outside of create_tmp_table() function.


sql/sql_select.cc:
  create_tmp_table():
    Moved code which is responsible for determining if optimization
    which pushes down LIMIT clause to temporary table creation is
    applicable out of this function.
    Such move made this function independant of THD::lex::current_select
    value and removed valgrind warnings which occured in cases when this
    member pointed to uninitialized SELECT_LEX object (particularly these
    warnings occured in sp-prelocking.test and information_schema.test
    in 5.0). This seems like a better solution than trying to force this
    pointer always to point to relevant select because:
    - In some cases when we use create_tmp_table() there are no relevant
      SELECT_LEX object (we use it just to create temporary table/object).
    - There is only one place in code where we call this funciton and
      where this optimization can be enabled. And in this place we
      already have some logic which tries to determine if it is applicable.
