288da1d759 Final step of Take 7 on review fixes of this
fairly complex bug


mysql-test/r/partition.result:
  Merge fix
sql/partition_info.cc:
  Moved method from sql_partition.cc to the partition_info class
sql/partition_info.h:
  Introduced a number of charset related arrays
  Removed some bools that could be checked by checking arrays instead
sql/sql_partition.cc:
  Introduced a number of charset related arrays
  Removed some bools that could be checked by checking arrays instead
  Made method of common complex if-statement
  Made that method and check of partition function fields public methods
  to enable use from partition_info class.
  Moved method to partition_info class
  Optimised copy_to_part_field_buffers method to avoid as much as possible
  calculations in those. Also avoided double calls when both subpartitioning
  and partitioning
  Handled review comments
sql/sql_partition.h:
  New methods public for use in partition_info class
sql/sql_yacc.yy:
  Missed this in previous merge and review fixes

e0d2f525fe Fix for bug#20670 "UPDATE using key and invoking trigger that modifies
this key does not stop" (5.1 version).

UPDATE statement which WHERE clause used key and which invoked trigger
that modified field in this key worked indefinetely.

This problem occured because in cases when UPDATE statement was
executed in update-on-the-fly mode (in which row is updated right
during evaluation of select for WHERE clause) the new version of
the row became visible to select representing WHERE clause and was
updated again and again.
We already solve this problem for UPDATE statements which does not
invoke triggers by detecting the fact that we are going to update
field in key used for scanning and performing update in two steps,
during the first step we gather information about the rows to be
updated and then doing actual updates. We also do this for
MULTI-UPDATE and in its case we even detect situation when such
fields are updated in triggers (actually we simply assume that
we always update fields used in key if we have before update
trigger).

The fix simply extends this check which is done with help of
check_if_key_used()/QUICK_SELECT_I::check_if_keys_used()
routine/method in such way that it also detects cases when
field used in key is updated in trigger. We do this by
changing check_if_key_used() to take field bitmap instead
field list as argument and passing TABLE::write_set
to it (we also have to add info about fields used in
triggers to this bitmap a bit earlier).
As nice side-effect we have more precise and thus more optimal
perfomance-wise check for the MULTI-UPDATE.
Also check_if_key_used() routine and similar method were renamed
to is_key_used()/is_keys_used() in order to better reflect that
it is simple boolean predicate.
Finally, partition_key_modified() routine now also takes field
bitmap instead of field list as argument.


sql/key.cc:
  Now check_if_key_used() takes field bitmap instead of field list as
  argument (bitmaps are also used in its implementation).
  It is no longer responsible for checking if key uses automatically
  updated TIMESTAMP fields, instead callers should properly mark such
  fields in field bitmap.
  Also renamed this function to is_key_used().
sql/mysql_priv.h:
  Renamed check_if_key_used() to is_key_used(), also now this routine
  takes field bitmap instead of field list as argument.
sql/opt_range.cc:
  QUICK_SELECT_I::check_if_keys_used() method and check_if_key_used()
  routine were renamed to is_keys_used()/is_key_used(). Also now they
  take bitmap instead of field list as argument.
sql/opt_range.h:
  QUICK_SELECT_I::check_if_key_used() method was renamed to is_keys_used().
  Now it takes field bitmap instead of field list as argument and no
  longer responsible for checking if key uses automatically updated
  TIMESTAMP fields. Instead callers should properly mark such fields
  in field bitmap.
sql/sql_partition.cc:
  partition_key_modified() now takes field bitmap instead of list
  as argument.
sql/sql_partition.h:
  partition_key_modified() now takes field bitmap as argument
  instead of field list.
sql/sql_update.cc:
  To detect situation in which trigger modifies part of key which is
  going to be used for processing of where clause and thus makes
  processing of this update with update-on-the-fly method unsafe
  we use check_if_key_used() routine and similar method (which were
  renamed to is_key_used()) plus information from TABLE::write_map
  bitmap. Note that we have to call TABLE::mark_columns_needed_for_update()
  method earlier now to fill this bitmap with information about fields
  updated in triggers.
  safe_update_on_fly() routine now uses the same approach and no
  longer needs list of fields as argument.
