7efdc62f9d BUG#21081: SELECT inside stored procedure returns wrong results 
Re-execution of a parametrized prepared statement or a stored routine
with a SELECT that use LEFT JOIN with second table having only one row
could yield incorrect result.

The problem appeared only for left joins with second table having only
one row (aka const table) and equation conditions in ON or WHERE clauses
that depend on the argument passed.  Once the condition was false for
second const table, a NULL row was created for it, and any field involved
got NULL-value flag, which then was never reset.

The cause of the problem was that Item_field::null_value could be set
without being reset for re-execution.  The solution is to reset
Item_field::null_value in Item_field::cleanup().


mysql-test/r/ps.result:
  Add result for bug#21081: SELECT inside stored procedure returns wrong
  results.
mysql-test/t/ps.test:
  Add test case for bug#21081: SELECT inside stored procedure returns wrong

c1bbfb2b67 Fixed bug #18360: Type aggregation for IN and CASE may lead to a wrong 
result

The IN function aggregates result types of all expressions. It uses that 
type in comparison of left expression and expressions in right part. 
This approach works in most cases. But let's consider the case when the
right part contains both strings and integers. In that case this approach may
cause wrong results because all strings which do not start with a digit are
evaluated as 0.
CASE uses the same approach when a CASE expression is given thus it's also
affected.

The idea behind this fix is to make IN function to compare expressions with
different result types differently. For example a string in the left
part will be compared as string with strings specified in right part and
will be converted to real for comparison to int or real items in the right
part.

A new function called collect_cmp_types() is added. It collects different
result types for comparison of first item in the provided list with each 
other item in the list. 

The Item_func_in class now can refer up to 5 cmp_item objects: 1 for each
result type for comparison purposes. cmp_item objects are allocated according
to found result types. The comparison of the left expression with any
right part expression is now based only on result types of these expressions.

The Item_func_case class is modified in the similar way when a CASE
expression is specified. Now it can allocate up to 5 cmp_item objects
to compare CASE expression with WHEN expressions of different types.
The comparison of the CASE expression with any WHEN expression now based only 
on result types of these expressions.

  Fixed bug #21698.
  Added an implementation of the compile method for class Item_cond.
  First it processes the Item_cond node with a callback function and if

7a11df8c93 Fixed bug#21475: Wrongly applied constant propagation leads to a false comparison. 
A date can be represented as an int (like 20060101) and as a string (like
"2006.01.01"). When a DATE/TIME field is compared in one SELECT against both
representations the constant propagation mechanism leads to comparison
of DATE as a string and DATE as an int. In this example it compares 2006 and
20060101 integers. Obviously it fails comparison although they represents the
same date.


Now the Item_bool_func2::fix_length_and_dec() function sets the comparison
context for items being compared. I.e. if items compared as strings the
comparison context is STRING.
The constant propagation mechanism now doesn't mix items used in different
comparison contexts. The context check is done in the
Item_field::equal_fields_propagator() and in the change_cond_ref_to_const() 
functions.

Also the better fix for bug 21159 is introduced.

35209c68ea Fixed bug#12185: Data type aggregation may produce wrong result 
The Item::tmp_table_field_from_field_type() function creates Field_datetime
object instead of Field_timestamp object for timestamp field thus always
changing data type is a tmp table is used.

The Field_blob object constructor which is used in the 
Item::tmp_table_field_from_field_type() is always setting packlength field of
newly created blob to 4. This leads to changing fields data type for example
from the blob to the longblob if a temporary table is used.

The Item::make_string_field() function always converts Field_string objects 
to Field_varstring objects. This leads to changing data type from the 
char/binary to varchar/varbinary.

Added appropriate Field_timestamp object constructor for using in the 
Item::tmp_table_field_from_field_type() function.

Added Field_blob object constructor which sets pack length according to
max_length argument.

The Item::tmp_table_field_from_field_type() function now creates
Field_timestamp object for a timestamp field.

The Item_type_holder::display_length() now returns correct NULL length NULL
length. 

The Item::make_string_field() function now doesn't change Field_string to
Field_varstring in the case of Item_type_holder. 

The Item::tmp_table_field_from_field_type() function now uses the Field_blob
constructor which sets packlength according to max_length.

  Field_timestamp object for a timestamp field.
  The Item::tmp_table_field_from_field_type() function now uses the Field_blob
  constructor which sets packlength according to max_length.

ca00a985a1 Bug#21013: Performance Degrades when importing data that uses Trigger 
and Stored Procedure

The essence of the bug was that for every re-execution of stored
routine or prepared statement new items for character set conversions
were created, thus increasing the number of items and the time of their
processing, and creating memory leak.

No test case is provided since current test suite can't cover such type
of bugs.

0e47753ffd After merge fixes for patch solving bug#18437 "Wrong values inserted with a 
before update trigger on NDB table".

Two main changes:
- We use TABLE::read_set/write_set bitmaps for marking fields used by
  statement instead of Field::query_id in 5.1.
- Now when we mark columns used by statement we take into account columns 
  used by table's triggers instead of marking all columns as used if table
  has triggers.


mysql-test/r/federated.result:
  Changed test in order to make it work with RBR.
  RBR changes the way in which we execute "DELETE FROM t1" statement - we don't
  use handler::delete_all_rows() method if RBR is enabled (see bug#19066).
  As result federated engine produces different sequences of statements for
  remote server in non-RBR and in RBR cases. And this changes order of the
  rows inserted by following INSERT statements.

  As result federated engine produces different sequences of statements for

sql/ha_partition.cc:
  Added handling of HA_EXTRA_WRITE_CAN_REPLACE/HA_EXTRA_WRITE_CANNOT_REPLACE
  to ha_partition::extra().
sql/item.cc:
  Adjusted comment after merge. In 5.1 we use TABLE::read_set/write_set
  bitmaps instead of Field::query_id for marking columns used.
sql/log_event.cc:
  Write_rows_log_event::do_before_row_operations():
    Now we explicitly inform handler that we want to replace rows so it can
    promote operation done by write_row() to replace.
sql/mysql_priv.h:
  Removed declaration of mark_fields_used_by_triggers_for_insert_stmt() which
  is no longer used (we have TABLE::mark_columns_needed_for_insert() instead).
sql/sql_insert.cc:
  Adjusted code after merge. Get rid of mark_fields_used_by_triggers_for_insert_stmt()
  as now we use TABLE::mark_columns_needed_for_insert() for the same purprose.
  Aligned places where we call this method with places where we call
  mark_fields_used_by_triggers_for_insert() in 5.0.
  Finally we no longer need to call handler::extra(HA_EXTRA_WRITE_CAN_REPLACE)
  in case of REPLACE statement since in 5.1 write_record() marks all columns
  as used before doing actual row replacement.
sql/sql_load.cc:
  Adjusted code after merge. In 5.1 we use TABLE::mark_columns_needed_for_insert() instead of
  mark_fields_used_by_triggers_for_insert_stmt() routine. We also no longer
  need to call handler::extra(HA_EXTRA_RETRIEVE_ALL_COLS) if we execute LOAD
  DATA REPLACE since in 5.1 write_record() will mark all columns as used before
  doing actual row replacement.
sql/sql_trigger.cc:
  Table_triggers_list::mark_fields_used():
    We use TABLE::read_set/write_set bitmaps for marking fields used instead
    of Field::query_id in 5.1.
sql/sql_trigger.h:
  TABLE::mark_columns_needed_for_* methods no longer need to be friends of
  Table_triggers_list class as intead of dirrectly accessing its private
  members they can use public Table_triggers_list::mark_fields_used() method.
  Also Table_triggers)list::mark_fields_used() no longer needs THD argument.
sql/table.cc:
  TABLE::mark_columns_needed_for_*():
    Now we mark columns which are really used by table's triggers instead of
    marking all columns as used if table has triggers.

ae9724cce1 Fix for bug#18437 "Wrong values inserted with a before update trigger on 
NDB table".

SQL-layer was not marking fields which were used in triggers as such. As
result these fields were not always properly retrieved/stored by handler
layer. So one might got wrong values or lost changes in triggers for NDB,
Federated and possibly InnoDB tables.
This fix solves the problem by marking fields used in triggers
appropriately.

Also this patch contains the following cleanup of ha_ndbcluster code:

We no longer rely on reading LEX::sql_command value in handler in order
to determine if we can enable optimization which allows us to handle REPLACE
statement in more efficient way by doing replaces directly in write_row()
method without reporting error to SQL-layer.
Instead we rely on SQL-layer informing us whether this optimization
applicable by calling handler::extra() method with
HA_EXTRA_WRITE_CAN_REPLACE flag.
As result we no longer apply this optimzation in cases when it should not
be used (e.g. if we have on delete triggers on table) and use in some
additional cases when it is applicable (e.g. for LOAD DATA REPLACE).

Finally this patch includes fix for bug#20728 "REPLACE does not work
correctly for NDB table with PK and unique index".
  
This was yet another problem which was caused by improper field mark-up.
During row replacement fields which weren't explicity used in REPLACE
statement were not marked as fields to be saved (updated) so they have
retained values from old row version. The fix is to mark all table
fields as set for REPLACE statement. Note that in 5.1 we already solve
this problem by notifying handler that it should save values from all
fields only in case when real replacement happens.


include/my_base.h:
  Added HA_EXTRA_WRITE_CAN_REPLACE, HA_EXTRA_WRITE_CANNOT_REPLACE - new
  parameters for ha_extra() method. We use them to inform handler that
  write_row() which tries to insert new row into the table and encounters
  some already existing row with same primary/unique key can replace old
  row with new row instead of reporting error.
mysql-test/r/federated.result:
  Additional test for bug#18437 "Wrong values inserted with a before update
  trigger on NDB table".
mysql-test/r/ndb_replace.result:
  Added test for bug #20728 "REPLACE does not work correctly for NDB table
  with PK and unique index". Updated wrong results from older test.

  statement in more efficient way by doing replaces directly in write_row()

    Added comment explaining why we don't set Field::query_id in this method.
sql/mysql_priv.h:
  mysql_alter_table() function no longer takes handle_duplicates argument.
  Added declaration of mark_fields_used_by_triggers_for_insert_stmt() function.
sql/sql_delete.cc:
  Mark fields which are used by ON DELETE triggers so handler will retrieve
  values for these fields.
sql/sql_insert.cc:
  Explicitly inform handler that we are doing REPLACE (using ha_extra() method)
  in cases when it can promote insert operation done by write_row() to replace.
  Also when we do REPLACE we want to store values for all columns so we should
  inform handler about it.
  Finally we should mark fields used by ON UPDATE/ON DELETE triggers as such
  so handler can properly retrieve/restore values in these fields during
  execution of REPLACE and INSERT ... ON DUPLICATE KEY UPDATE statements.
sql/sql_load.cc:
  Explicitly inform handler that we are doing LOAD DATA REPLACE (using
  ha_extra() method) in cases when it can promote insert operation done by
  write_row() to replace.
  Also when we do replace we want to save (replace) values for all columns
  so we should inform handler about it.
  Finally to properly execute LOAD DATA for table with triggers we should
  mark fields used by ON INSERT triggers as such so handler can properly
  store values for these fields.
sql/sql_parse.cc:
  mysql_alter_table() function no longer takes handle_duplicates argument.
sql/sql_table.cc:
  Got rid of handle_duplicates argument in mysql_alter_table() and
  copy_data_between_tables() functions. These functions were always
  called with handle_duplicates == DUP_ERROR and thus contained dead
  (and probably incorrect) code.
sql/sql_trigger.cc:
  Added Table_triggers_list::mark_fields_used() method which is used to mark
  fields read/set by triggers as such so handlers will be able properly
  retrieve/store values in these fields.
sql/sql_trigger.h:
  Table_triggers_list:
    Added mark_fields_used() method which is used to mark fields read/set by
    triggers as such so handlers will be able properly retrieve/store values
    in these fields. To implement this method added 'trigger_fields' member
    which is array of lists linking items for all fields used in triggers
    grouped by event and action time.
sql/sql_update.cc:
  Mark fields which are used by ON UPDATE triggers so handler will retrieve
  and save values for these fields.
mysql-test/r/ndb_trigger.result:
  Added test for bug#18437 "Wrong values inserted with a before update trigger

01d03e7b4b This changeset is largely a handler cleanup changeset (WL#3281), but includes fixes and cleanups that was found necessary while testing the handler changes 
Changes that requires code changes in other code of other storage engines.
(Note that all changes are very straightforward and one should find all issues
by compiling a --debug build and fixing all compiler errors and all
asserts in field.cc while running the test suite),

- New optional handler function introduced: reset()
  This is called after every DML statement to make it easy for a handler to
  statement specific cleanups.
  (The only case it's not called is if force the file to be closed)

- handler::extra(HA_EXTRA_RESET) is removed. Code that was there before
  should be moved to handler::reset()

- table->read_set contains a bitmap over all columns that are needed
  in the query.  read_row() and similar functions only needs to read these
  columns
- table->write_set contains a bitmap over all columns that will be updated
  in the query. write_row() and update_row() only needs to update these
  columns.
  The above bitmaps should now be up to date in all context
  (including ALTER TABLE, filesort()).

  The handler is informed of any changes to the bitmap after
  fix_fields() by calling the virtual function
  handler::column_bitmaps_signal(). If the handler does caching of
  these bitmaps (instead of using table->read_set, table->write_set),
  it should redo the caching in this code. as the signal() may be sent
  several times, it's probably best to set a variable in the signal
  and redo the caching on read_row() / write_row() if the variable was
  set.

- Removed the read_set and write_set bitmap objects from the handler class

- Removed all column bit handling functions from the handler class.
  (Now one instead uses the normal bitmap functions in my_bitmap.c instead
  of handler dedicated bitmap functions)

- field->query_id is removed. One should instead instead check
  table->read_set and table->write_set if a field is used in the query.

- handler::extra(HA_EXTRA_RETRIVE_ALL_COLS) and
  handler::extra(HA_EXTRA_RETRIEVE_PRIMARY_KEY) are removed. One should now
  instead use table->read_set to check for which columns to retrieve.

- If a handler needs to call Field->val() or Field->store() on columns
  that are not used in the query, one should install a temporary
  all-columns-used map while doing so. For this, we provide the following
  functions:

  my_bitmap_map *old_map= dbug_tmp_use_all_columns(table, table->read_set);
  field->val();
  dbug_tmp_restore_column_map(table->read_set, old_map);

  and similar for the write map:

  my_bitmap_map *old_map= dbug_tmp_use_all_columns(table, table->write_set);
  field->val();
  dbug_tmp_restore_column_map(table->write_set, old_map);

  If this is not done, you will sooner or later hit a DBUG_ASSERT
  in the field store() / val() functions.
  (For not DBUG binaries, the dbug_tmp_restore_column_map() and
  dbug_tmp_restore_column_map() are inline dummy functions and should
  be optimized away be the compiler).

- If one needs to temporary set the column map for all binaries (and not
  just to avoid the DBUG_ASSERT() in the Field::store() / Field::val()
  methods) one should use the functions tmp_use_all_columns() and
  tmp_restore_column_map() instead of the above dbug_ variants.

- All 'status' fields in the handler base class (like records,
  data_file_length etc) are now stored in a 'stats' struct. This makes
  it easier to know what status variables are provided by the base
  handler.  This requires some trivial variable names in the extra()
  function.

- New virtual function handler::records().  This is called to optimize
  COUNT(*) if (handler::table_flags() & HA_HAS_RECORDS()) is true.
  (stats.records is not supposed to be an exact value. It's only has to
  be 'reasonable enough' for the optimizer to be able to choose a good
  optimization path).

- Non virtual handler::init() function added for caching of virtual
  constants from engine.

- Removed has_transactions() virtual method. Now one should instead return
  HA_NO_TRANSACTIONS in table_flags() if the table handler DOES NOT support
  transactions.

- The 'xxxx_create_handler()' function now has a MEM_ROOT_root argument
  that is to be used with 'new handler_name()' to allocate the handler
  in the right area.  The xxxx_create_handler() function is also
  responsible for any initialization of the object before returning.

  For example, one should change:

  static handler *myisam_create_handler(TABLE_SHARE *table)
  {
    return new ha_myisam(table);
  }

  ->

  static handler *myisam_create_handler(TABLE_SHARE *table, MEM_ROOT *mem_root)
  {
    return new (mem_root) ha_myisam(table);
  }

- New optional virtual function: use_hidden_primary_key().
  This is called in case of an update/delete when
  (table_flags() and HA_PRIMARY_KEY_REQUIRED_FOR_DELETE) is defined
  but we don't have a primary key. This allows the handler to take precisions
  in remembering any hidden primary key to able to update/delete any
  found row. The default handler marks all columns to be read.

- handler::table_flags() now returns a ulonglong (to allow for more flags).

- New/changed table_flags()
  - HA_HAS_RECORDS	    Set if ::records() is supported
  - HA_NO_TRANSACTIONS	    Set if engine doesn't support transactions
  - HA_PRIMARY_KEY_REQUIRED_FOR_DELETE
                            Set if we should mark all primary key columns for
			    read when reading rows as part of a DELETE
			    statement. If there is no primary key,
			    all columns are marked for read.
  - HA_PARTIAL_COLUMN_READ  Set if engine will not read all columns in some
			    cases (based on table->read_set)
 - HA_PRIMARY_KEY_ALLOW_RANDOM_ACCESS
   			    Renamed to HA_PRIMARY_KEY_REQUIRED_FOR_POSITION.
 - HA_DUPP_POS              Renamed to HA_DUPLICATE_POS
 - HA_REQUIRES_KEY_COLUMNS_FOR_DELETE
			    Set this if we should mark ALL key columns for
			    read when when reading rows as part of a DELETE
			    statement. In case of an update we will mark
			    all keys for read for which key part changed
			    value.
  - HA_STATS_RECORDS_IS_EXACT
			     Set this if stats.records is exact.
			     (This saves us some extra records() calls
			     when optimizing COUNT(*))
			    

- Removed table_flags()
  - HA_NOT_EXACT_COUNT     Now one should instead use HA_HAS_RECORDS if
			   handler::records() gives an exact count() and
			   HA_STATS_RECORDS_IS_EXACT if stats.records is exact.
  - HA_READ_RND_SAME	   Removed (no one supported this one)

- Removed not needed functions ha_retrieve_all_cols() and ha_retrieve_all_pk()

- Renamed handler::dupp_pos to handler::dup_pos

- Removed not used variable handler::sortkey


Upper level handler changes:

- ha_reset() now does some overall checks and calls ::reset()
- ha_table_flags() added. This is a cached version of table_flags(). The
  cache is updated on engine creation time and updated on open.


MySQL level changes (not obvious from the above):

- DBUG_ASSERT() added to check that column usage matches what is set
  in the column usage bit maps. (This found a LOT of bugs in current
  column marking code).

- In 5.1 before, all used columns was marked in read_set and only updated
  columns was marked in write_set. Now we only mark columns for which we
  need a value in read_set.

- Column bitmaps are created in open_binary_frm() and open_table_from_share().
  (Before this was in table.cc)

- handler::table_flags() calls are replaced with handler::ha_table_flags()

- For calling field->val() you must have the corresponding bit set in
  table->read_set. For calling field->store() you must have the
  corresponding bit set in table->write_set. (There are asserts in
  all store()/val() functions to catch wrong usage)

- thd->set_query_id is renamed to thd->mark_used_columns and instead
  of setting this to an integer value, this has now the values:
  MARK_COLUMNS_NONE, MARK_COLUMNS_READ, MARK_COLUMNS_WRITE
  Changed also all variables named 'set_query_id' to mark_used_columns.

- In filesort() we now inform the handler of exactly which columns are needed
  doing the sort and choosing the rows.

- The TABLE_SHARE object has a 'all_set' column bitmap one can use
  when one needs a column bitmap with all columns set.
  (This is used for table->use_all_columns() and other places)

- The TABLE object has 3 column bitmaps:
  - def_read_set     Default bitmap for columns to be read
  - def_write_set    Default bitmap for columns to be written
  - tmp_set          Can be used as a temporary bitmap when needed.
  The table object has also two pointer to bitmaps read_set and write_set
  that the handler should use to find out which columns are used in which way.

- count() optimization now calls handler::records() instead of using
  handler->stats.records (if (table_flags() & HA_HAS_RECORDS) is true).

- Added extra argument to Item::walk() to indicate if we should also
  traverse sub queries.

- Added TABLE parameter to cp_buffer_from_ref()

- Don't close tables created with CREATE ... SELECT but keep them in
  the table cache. (Faster usage of newly created tables).


New interfaces:

- table->clear_column_bitmaps() to initialize the bitmaps for tables
  at start of new statements.

- table->column_bitmaps_set() to set up new column bitmaps and signal
  the handler about this.

- table->column_bitmaps_set_no_signal() for some few cases where we need
  to setup new column bitmaps but don't signal the handler (as the handler
  has already been signaled about these before). Used for the momement
  only in opt_range.cc when doing ROR scans.

- table->use_all_columns() to install a bitmap where all columns are marked
  as use in the read and the write set.

- table->default_column_bitmaps() to install the normal read and write
  column bitmaps, but not signaling the handler about this.
  This is mainly used when creating TABLE instances.

- table->mark_columns_needed_for_delete(),
  table->mark_columns_needed_for_delete() and
  table->mark_columns_needed_for_insert() to allow us to put additional
  columns in column usage maps if handler so requires.
  (The handler indicates what it neads in handler->table_flags())

- table->prepare_for_position() to allow us to tell handler that it
  needs to read primary key parts to be able to store them in
  future table->position() calls.
  (This replaces the table->file->ha_retrieve_all_pk function)

- table->mark_auto_increment_column() to tell handler are going to update
  columns part of any auto_increment key.

- table->mark_columns_used_by_index() to mark all columns that is part of
  an index.  It will also send extra(HA_EXTRA_KEYREAD) to handler to allow
  it to quickly know that it only needs to read colums that are part
  of the key.  (The handler can also use the column map for detecting this,
  but simpler/faster handler can just monitor the extra() call).

- table->mark_columns_used_by_index_no_reset() to in addition to other columns,
  also mark all columns that is used by the given key.

- table->restore_column_maps_after_mark_index() to restore to default
  column maps after a call to table->mark_columns_used_by_index().

- New item function register_field_in_read_map(), for marking used columns
  in table->read_map. Used by filesort() to mark all used columns

- Maintain in TABLE->merge_keys set of all keys that are used in query.
  (Simplices some optimization loops)

- Maintain Field->part_of_key_not_clustered which is like Field->part_of_key
  but the field in the clustered key is not assumed to be part of all index.
  (used in opt_range.cc for faster loops)

-  dbug_tmp_use_all_columns(), dbug_tmp_restore_column_map()
   tmp_use_all_columns() and tmp_restore_column_map() functions to temporally
   mark all columns as usable.  The 'dbug_' version is primarily intended
   inside a handler when it wants to just call Field:store() & Field::val()
   functions, but don't need the column maps set for any other usage.
   (ie:: bitmap_is_set() is never called)

- We can't use compare_records() to skip updates for handlers that returns
  a partial column set and the read_set doesn't cover all columns in the
  write set. The reason for this is that if we have a column marked only for
  write we can't in the MySQL level know if the value changed or not.
  The reason this worked before was that MySQL marked all to be written
  columns as also to be read. The new 'optimal' bitmaps exposed this 'hidden
  bug'.

- open_table_from_share() does not anymore setup temporary MEM_ROOT
  object as a thread specific variable for the handler. Instead we
  send the to-be-used MEMROOT to get_new_handler().
  (Simpler, faster code)



Bugs fixed:

- Column marking was not done correctly in a lot of cases.
  (ALTER TABLE, when using triggers, auto_increment fields etc)
  (Could potentially result in wrong values inserted in table handlers
  relying on that the old column maps or field->set_query_id was correct)
  Especially when it comes to triggers, there may be cases where the
  old code would cause lost/wrong values for NDB and/or InnoDB tables.

- Split thd->options flag OPTION_STATUS_NO_TRANS_UPDATE to two flags:
  OPTION_STATUS_NO_TRANS_UPDATE and OPTION_KEEP_LOG.
  This allowed me to remove some wrong warnings about:
  "Some non-transactional changed tables couldn't be rolled back"

- Fixed handling of INSERT .. SELECT and CREATE ... SELECT that wrongly reset
  (thd->options & OPTION_STATUS_NO_TRANS_UPDATE) which caused us to loose
  some warnings about
  "Some non-transactional changed tables couldn't be rolled back")

- Fixed use of uninitialized memory in ha_ndbcluster.cc::delete_table()
  which could cause delete_table to report random failures.

- Fixed core dumps for some tests when running with --debug

- Added missing FN_LIBCHAR in mysql_rm_tmp_tables()
  (This has probably caused us to not properly remove temporary files after
  crash)

- slow_logs was not properly initialized, which could maybe cause
  extra/lost entries in slow log.

- If we get an duplicate row on insert, change column map to read and
  write all columns while retrying the operation. This is required by
  the definition of REPLACE and also ensures that fields that are only
  part of UPDATE are properly handled.  This fixed a bug in NDB and
  REPLACE where REPLACE wrongly copied some column values from the replaced
  row.

- For table handler that doesn't support NULL in keys, we would give an error
  when creating a primary key with NULL fields, even after the fields has been
  automaticly converted to NOT NULL.

- Creating a primary key on a SPATIAL key, would fail if field was not
  declared as NOT NULL.


Cleanups:

- Removed not used condition argument to setup_tables

- Removed not needed item function reset_query_id_processor().

- Field->add_index is removed. Now this is instead maintained in
  (field->flags & FIELD_IN_ADD_INDEX)

- Field->fieldnr is removed (use field->field_index instead)

- New argument to filesort() to indicate that it should return a set of
  row pointers (not used columns). This allowed me to remove some references
  to sql_command in filesort and should also enable us to return column
  results in some cases where we couldn't before.

- Changed column bitmap handling in opt_range.cc to be aligned with TABLE
  bitmap, which allowed me to use bitmap functions instead of looping over
  all fields to create some needed bitmaps. (Faster and smaller code)

- Broke up found too long lines

- Moved some variable declaration at start of function for better code
  readability.

- Removed some not used arguments from functions.
  (setup_fields(), mysql_prepare_insert_check_table())

- setup_fields() now takes an enum instead of an int for marking columns
   usage.

- For internal temporary tables, use handler::write_row(),
  handler::delete_row() and handler::update_row() instead of
  handler::ha_xxxx() for faster execution.

- Changed some constants to enum's and define's.

- Using separate column read and write sets allows for easier checking
  of timestamp field was set by statement.

- Remove calls to free_io_cache() as this is now done automaticly in ha_reset()

- Don't build table->normalized_path as this is now identical to table->path
  (after bar's fixes to convert filenames)

- Fixed some missed DBUG_PRINT(.."%lx") to use "0x%lx" to make it easier to
  do comparision with the 'convert-dbug-for-diff' tool.


Things left to do in 5.1:

- We wrongly log failed CREATE TABLE ... SELECT in some cases when using
  row based logging (as shown by testcase binlog_row_mix_innodb_myisam.result)
  Mats has promised to look into this.

- Test that my fix for CREATE TABLE ... SELECT is indeed correct.
  (I added several test cases for this, but in this case it's better that
  someone else also tests this throughly).
  Lars has promosed to do this.

  create_xxx handler now takes MEMROOT as an argument to simplify memory allocation.
  Much simpler get_new_handler()
  (Initialization of the object is now handled by the create method for the engine)
  Moved all allocation of bitmap handling to the TABLE object (in table.cc)
  Added column_bitmaps_signal() to signal column usage changes.

  Added use_hidden_primary_key() to signal handler that we we are going to read and update + delete the row and the handler should thus remember the position for the row
sql/handler.h:
  Added HA_NO_TRANSACTIONS, HA_PARTIAL_COLUMN_READ, HA_REQUIRES_KEY_COLUMNS_FOR_DELETE,HA_PRIMARY_KEY_REQUIRED_FOR_DELETE and HA_HAS_RECORDS
  Removed HA_NOT_EXACT_COUNT, HA_READ_RND_SAME
  HA_DUPP_POS -> HA_DUPLICATE_POS
  HA_NOT_EXACT_COUNT replaced by HA_STATS_RECORDS_IS_EXACT, HA_HAS_RECORDS and records()
  HA_PRIMARY_KEY_ALLOW_RANDOM_ACCESS renamed to HA_PRIMARY_KEY_REQUIRED_FOR_POSITION
  Added future row type 'ROW_TYPE_PAGES'
  Added MEM_ROOT to handlerton 'create' function
  Added ha_statistics, a structure for all status variable in the base handler class.
  Moved all status variables in the handler class into a stats structs to improve readability.
  ha_table_flags() is now a cached (not virtual) version of table_flags()
  reset() doesn't anymore call extra(HA_EXTRA_RESET) but is a function of it's own.
  Renamed dupp_ref to dup_ref
  Renamed not used handler::sortkey
  Moved read_set and write_set to TABLE structure
  handler::init() function added for cacheing of virtual constants from engine.
sql/item.cc:
  Added register_field_in_read_map() for marking used columns in expression.
  This is used by filesort() for creating an optimal column bitmap while retrieving columns for sorting.
  Initalize value.cs_info.character_set_client to fix core dump bug with --debug
  set_query_id -> mark_used_columns
  Mark used columns in read_set OR write_set.
sql/item.h:
  Removed reset_query_id_processor() as it's not needed anymore.
  Added register_field_in_read_map()
  Added extra argument to Item::walk() to indicate if we should also
  traverse sub queries.
sql/item_cmpfunc.cc:
  Temporary mark used columns to be read/writable
  Update Item::walk to new interface
sql/item_cmpfunc.h:
  Added extra argument to Item::walk() to indicate if we should also traverse sub queries.

  Update Item::walk() to new interface
  table_flags() -> ha_table_flags()
sql/item_func.h:
  Update Item::walk() to new interface
sql/item_row.cc:
  Update Item::walk() to new interface
sql/item_row.h:
  Update Item::walk() to new interface
sql/item_strfunc.h:
  Update Item::walk() to new interface
sql/item_subselect.cc:
  Added Item_subselect::walk()
  (It was a bug it was missing before. Not sure what kind of bugs this could have caused)
sql/item_subselect.h:
  Update Item::walk() to new interface
sql/item_sum.cc:
  Update Item::walk() to new interface
  Updates for new handler interace
sql/item_sum.h:
  Update Item::walk() to new interface
sql/key.cc:
  Updates for new handler interace
sql/log.cc:
  Mark all columns used for log tables
  Split options flag
  Ensured that second argument to trans_register_ha is a bool
sql/log_event.cc:
  Fixed comments to be withing 79 characters
  Use OPTION_KEEP_LOG instead of OPTION_STATUS_NO_TRANS_UPDATE to remove wrong warnings
  Updates for new handler interface
  Use 0x%lx instead of %p (portability problem)

sql/mysqld.cc:
  Indentation fixes and removed old comment
sql/opt_range.cc:
  Update to new handler and bitmap interface.
  Fixed calls to cp_buffer_from_ref() and walk() (new argument).
  Create new temporary bitmaps for ror scans.
  (Needed because of handler changes and to get more accurate column bitmaps than before)
  Remove not needed file->ha_reset() call before file->close().
  Some trivial optimization and indentation fixes.
  Use Field->part_of_key_not_clustered() to check if field is part of a key, instead of looping over all key parts.
  
  Added flag 'in_ror_merged_scan' to allow ::get_next() to know that we need a special column bitmap to only fetch pointer to record.
  This is needed because ror scan uses the same TABLE object but different file objects, which creates problem for the column bitmap handling.
  (This is a temporary solution. A better one would be to allocate an own TABLE object for ROR scans)
  
  Optimized bitmap handling in ror scans:
  - Start bitmap at position 0, not 1
  - Use same bitmap size as in TABLE
  - Use table->read_set and table->write_set to create column bitmaps instead of looping over all fields in table
sql/opt_range.h:
  Added 'in_ror_merged_scan' to indicate if we are doing a ROR scan
  Added temporary column bitmaps used in ROR scans
sql/opt_sum.cc:
  Added get_ext_record_count() which is used in COUNT() optimization if handler has HA_HAS_RECORDS
  Note that we don't call this if handler has HA_STATS_RECORDS_IS_EXACT set.
sql/protocol.cc:
  We need to mark columns as readable in ::store() as we sometimes return default value for fields to the user
sql/records.cc:
  Updates for new handler interface
sql/set_var.cc:
  Handle splitting OPTION_STATUS_NO_TRANS_UPDATE to two flags
sql/share/errmsg.txt:
  Fixed wrong

  Update call to setup_tables() to use new prototype
sql/sp_head.cc:
  Removed QQ comment
sql/spatial.cc:
  Removed wrong QQ comment
sql/sql_acl.cc:
  Mark that we need all columns for acl tables
  Supply memroot to some 'new' calls.
  Indentation fixes
sql/sql_base.cc:
  set_query_id removed
  Ensure we call ha_reset() at end of each statement
  Mark read columns in read_set and changed columns in write_set (Before all columns was marked in read set)
  Fixed marking of some columns that was not proplerly marked before
  Maintain in TABLE->merge_keys set of all keys that are used in some way
  Removed not used 'conds' argument from setup_tables()
  Remove not used setting of 'dupp_field' in insert_fields()
  Added missing FN_LIBCHAR in mysql_rm_tmp_tables()
  (This has probably caused us to not properly remove temporary files after crash)
sql/sql_bitmap.h:
  Added is_overlapping()
sql/sql_class.cc:
  Slow_logs was not properly initialized, which could maybe cause extra/lost entries in slow log.
  set_query_id -> mark_used_columns
  Simpler variable usage in pack_row()  (cleanup)
  Moved some variable declartion at start of function for better code readability
sql/sql_class.h:
  Added enum_mark_columns
  Updated comments
  Renamed dupp_field -> dup_field
  Added virtual function 'can_rollback_data()' to select_insert() to be used in CREATE ... SELECT to optimize use of OPTION_STATUS_NO_TRANS_UPDATE.
  (This fixes a bug in CREATE ... SELECT where we did give wrong warnings when using non transacational tables)
sql/sql_delete.cc:
  Updates to new handler interface
  Call table->mark_columns_needed_for_delete() to allow us to put additional columns in column usage maps if handler so requires.
  Call table->prepare_for_position() to tell handler that we are going to call ha_position().
  Removed call to free_io_cache(). (io_cache is now removed in ha_reset()).
  Fixed calls to setup_tables()
sql/sql_do.cc:
  Update call to setup_fields()
sql/sql_handler.cc:
  Tell handler tables to always read all columns.
  Use temporary column map when storing value in field for later index usage
sql/sql_help.cc:
  Makr all used fields to be read
  Update call to setup_fields()
sql/sql_insert.cc:
  Tell handler we are going to update the auto_increment column
  dupp_field -> dup_field
  Set column usage bits for timestamp field.
  Call table->mark_columns_needed_for_insert() and table->mark_auto_increment_column()
  Removed not used argument from mysql_prepare_insert_check_table().
  
  If we get an duplicate row on insert, change column map to read and write all columns while retrying the operatation.
  This is required by the definition of REPLACE and also ensures that fields that are only part of UPDATE are properly handled.
  This fixed a bug in NDB and REPLACE where REPLACE wrongly copied some column values from the replaced row.
  
  Setup new bitmaps for delayed insert rows
  Remove reseting of next_number_fields as it will be reset on next call to handler_insert()
  
  Fixed usage of thd->options and OPTION_STATUS_NO_TRANS_UPDATE.
  The issue was that one should not to reset this flag as it may be set by a previous statement.
  The way it was now used caused us to loose some warnings and get other wrong warnings when using non transactional tables mixed with transactional.
  I fixed it by introducing 'select_insert::can_rollback_data' to inform send_error() that the given statement can be rolled back (which in case of CREATE TABLE can always be done)
  Don't close tables created with CREATE ... SELECT but keep them in the table cache.
  
  Moved out MY_HOOKS from inside function (better readability)
sql/sql_load.cc:
  Update to use new handler and column marking interface
  Update using setup_tables()
sql/sql_olap.cc:
  Update calls to setup_tables
  Use enums instead of constants to setup_fields()
sql/sql_parse.cc:
  Handle OPTION_KEEP_LOG:
  - Set it on CREATE TEMPORARY TABLE / DROP TABLE
  - Reset it when OPTION_STATUS_NO_TRANS_UPDATE is reset
  - Don't set it for CREATE ... SELECT (this is handled in select_create class)
  Remove reseting of OPTION_STATUS_NO_TRANS_UPDATE in begin_trans() as this should already be reset.
  If in autocommit mode, reset OPTION_KEEP_LOG and OPTION_STATUS_NO_TRANS_UPDATE to not give warnings in future commands
sql/sql_partition.cc:
  Update walk() usage
  Trivial indentation fixes
sql/sql_plugin.cc:
  Mark all columns as used for plugins
sql/sql_prepare.cc:
  Added assert to find out hidden bugs in character_set_client (got an error in debug binary when this not set correctly)
  Updates for new handler interface
  Update calls to setup_fields()
sql/sql_repl.cc:
  Indentation fixes
sql/sql_select.cc:
  Update call to setup_tables() and setup_fields()

  Update to new hadler interface
  Indentation cleanups
  Added column bitmaps for temporary tables.
  Remove updating of the removed slots in the Field class
  Added TABLE argument to cp_buffer_from_ref() (To be able to install temporary column maps)
  For internal temporary tables, use handler::write_row(), handler::delete_row() and handler::update_row() instead of handler::ha_xxxx() for faster execution.
sql/sql_select.h:
  Indentaition fixes.
  Install temporary column usage maps when needed
  Added TABLE element to cp_buffer_from_ref()
sql/sql_show.cc:
  Update to new handler interface
  Mark all columns used for internal tables.
  Style fixes.
  Added support for 'future' ROW_TYPE_PAGES.
  Don't allocate TMP_TABLE_PARAM with calloc. The 'init()' function will initialize the structure properly.
sql/sql_table.cc:
  Update to new handler interface
  Simple my_snprintf -> strmake()
  Changed some constants to defines
  Don't test for NULL in primary key (as we a couple of line above force the PRIMARY KEY to be NOT NULL)
  Change field->add_index to use field->flags & FIELD_IN_ADD_INDEX
  Mark all columns as used for ALTER TABLE
  Style fixes
  Update call to filesort()
sql/sql_trigger.h:
  Added friend functions to be able to test if triggers exists for table we are going to insert/update or delete in.
sql/sql_udf.cc:
  Mark all columns as used for udf system table.
sql/sql_union.cc:
  Update call to walk()
  Update to new handler interface
sql/sql_update.cc:
  Remove query_id argument from compare_record()
  Use column bitmaps instead of query_id.
  We can't use compare_records() to skip updates for handlers that returns a partial column set and the read_set doesn't cover all columns in the write set, because compare_record() can't in this case know if a not read column changed value.
  Update call to setup_fields()
  Using separate column read and write sets allows for easier checking of timestamp field was set by statement.
  Removed call to free_io_cache() as this is now done in ha_reset()
  Call table->mark_columns_needed_for_update() and table->prepare_for_position()
  Style fixes
sql/sql_view.cc:
  Style fixes
sql/table.cc:

  Update call to walk()
  Added new functions:
  - st_table::clear_column_bitmaps()
  - st_table::prepare_for_position()
  - st_table::mark_columns_used_by_index()
  - st_table::restore_column_maps_after_mark_index()
  - st_table::mark_columns_used_by_index_no_reset()
  - st_table::mark_auto_increment_column()
  - st_table::mark_columns_needed_for_delete()

  Added to TABLE_SHARE all_set and column_bitmap_size
  Added to TABLE merge_keys, bitmap_init_values, def_read_set, def_write_set, tmp_set, read_set and write_set.
  Declared all new table column bitmap functions
  Added TABLE functions column_bitmaps_set(), column_bitmaps_set_no_signal(), use_all_columns() and default_column_bitmaps()
  Added functions: tmp_use_all_columns() and tmp_restore_column_map() to temporarly switch column bitmaps
  Added functions: dbug_tmp_use_all_columns() and dbug_tmp_restore_column_map() to temporarly switch column bitmaps to avoid asserts in Field::store() and Field::val().
