branches/zip: Fix bug# 46650:  Innodb assertion autoinc_lock == lock in lock_table_remove_low on INSERT SELECT

We only store the autoinc locks that are granted in the transaction's autoinc
lock vector. A transacton, that has been rolled back due to a deadlock because
of an AUTOINC lock attempt, will not have added that lock to the vector. We
need to check for that when we remove that lock.

branches/zip: lock_rec_validate_page(): Add the parameter zip_size.
This should help track down Mantis Issue #289.

The pthread_cond_wait implementations for windows might
dead lock in some rare circumstances.

1) One thread (I) enter a timed wait and at a point in
   time ends up after mutex unlock and before
   WaitForMultipleObjects(...)
2) Another thread (II) enters pthread_cond_broadcast.
   Grabs the mutex and discovers one waiter. It set
   the broadcast event and closes the broadcast gate
   then unlocks the mutex.
3) A third thread (III) issues a pthread_cond_signal.
   It grabs the mutex, discovers one waiter, sets the
   signal event then unlock the mutex.
4) The first threads (I) enters WaitForMultipleObjects
   and finds out that the signal object is in a
   signalled state and exits the wait.
5) Thread (I) grabs the mutex and checks result status.
   The number of waiters is decreased and becomes equal
   to 0. The event returned was a signal event so the
   broadcast gate isn't opened. The mutex is released.
6) Thread (II) issues a new broadcast. The mutex is
   acquired but the number of waiters are 0 hence
   the broadcast gate remains closed.
7) Thread (I) enters the wait again but is blocked by
   the broadcast gate.

      This fix resolves the above issue by always resetting
      broadcast gate when there are no more waiters in th queue.

  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
  - T be a transactional table and N non-transactional table.
  - B be begin, C commit and R rollback.
  - M be a mixed statement, i.e. a statement that updates both T and N.
  - M* be a mixed statement that fails while updating either T or N.

This patch restore the behavior presented in 5.1.37 for rows either produced in
the RBR or MIXED modes, when a M* statement that happened early in a transaction
had their changes written to the binary log outside the boundaries of the
transaction and wrapped in a BEGIN/ROLLBACK. This was done to keep the slave
consistent with with the master as the rollback would keep the changes on N and
undo them on T. In particular, we do what follows:

  . B M* T C would log - B M* R B T C.

Note that, 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. We do not fix the following case:

  . B T M* C would log B T M* C.

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 rollback the transaction as this would undo any uncommitted
changes on T tables.

SBR is not considered in this patch because a failing statement is written to
the binary along with the error code and a slave executes and then rolls back
the statement when it has an associated error code, thus undoing the effects
on T. In RBR and MBR, a full-fledged fix will be pushed after the WL 2687.

1. BUG#46256 - drop table with unknown collation crashes innodb

branches/5.1: fix bug#46256

Allow tables to be dropped even if the collation is not found,
but issue a warning.

Could not find an easy way to add mysql-test since it requires
changes to charsets and restarting the server. Tests were
executed manually.

1. BUG#46000 - using index called GEN_CLUST_INDEX crashes server

SELECT ... WHERE ... IN (NULL, ...) does full table scan,
even if the same query without the NULL uses efficient range scan.

The bugfix for the bug 18360 introduced an optimization:
if
  1) all right-hand arguments of the IN function are constants
  2) result types of all right argument items are compatible
     enough to use the same single comparison function to
     compare all of them to the left argument,

then

  we can convert the right-hand list of constant items to an array
  of equally-typed constant values for the further
  QUICK index access etc. (see Item_func_in::fix_length_and_dec()).

The Item_null constant item objects have STRING_RESULT
result types, so, as far as Item_func_in::fix_length_and_dec()
is aware of NULLs in the right list, this improvement efficiently
optimizes IN function calls with a mixed right list of NULLs and
string constants. However, the optimization doesn't affect mixed
lists of NULLs and integers, floats etc., because there is no
unique common comparator.


New optimization has been added to ignore the result type
of NULL constants in the static analysis of mixed right-hand lists.
This is safe, because at the execution phase we care about
presence of NULLs anyway.

1. The collect_cmp_types() function has been modified to optionally
   ignore NULL constants in the item list.
2. NULL-skipping code of the Item_func_in::fix_length_and_dec()
   function has been modified to work not only with in_string
   vectors but with in_vectors of other types.

rpl.rpl_trigger.test fails with valgrind errors with the innodb plugin

The problem is that there is only one autoinc value associated with 
the query when binlogging. If more than one autoinc values are used 
in the query, the autoinc values after the first one can be inserted 
wrongly on slave. So these autoinc values can become inconsistent on 
master and slave.

The problem is resolved by marking all the statements that invoke 
a trigger or call a function that updated autoinc fields as unsafe, 
and will switch to row-format in Mixed mode. Actually, the statement 
is safe if just one autoinc value is used in sub-statement, but it's 
impossible to check how many autoinc values are used in sub-statement.)

                    Removes the need of a hack (the jump to label).

On Mac OS X or Windows, sending a SIGHUP to the server or a
asynchronous flush (triggered by flush_time), would cause the
server to crash.

The problem was that a hook used to detach client API handles
wasn't prepared to handle cases where the thread does not have
a associated session.

The solution is to verify whether the thread has a associated
session before trying to detach a handle.

Make configure.js bail with an error if trying to build bdb from a bzr
tree.

          'flush tables' crashes

The server crashes when 'show procedure status' and 'flush tables' are
run concurrently.

This is caused by the way mysql.proc table is added twice to the list
of table to lock although the requirements on the current locking API
assumes differently.

No test case is submitted because of the nature of the crash which is 
currently difficult to reproduce in a deterministic way.

This is a backport from 5.1
