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.

  partition_create_handler() is now responsible for initialisation of the partition object
  Some trivial optimizations and indentation fixes
  Ensure that table_flags() are up to date
  Removed documentation for removed HA_EXTRA flags
  Fixed 'strange' usage of m_file[i] in new_handlers_from_part_info()that worked in current code 'by chance'
sql/ha_partition.h:
  Update to 'newer' table handler interface
sql/handler.cc:
  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.
  Changed binlog_log_row() to use the exiusting all_set bitmap in the table object.

  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:

  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.

  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

  Mark that we are using all columns for the proc table
  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()
  Remove some old disabled code
  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:
  Remove implicitely include 'errno.h'
  Remove code for building normalized path, as this is now identical to 'path'
  Remove field->fieldnr
  Added update of field->part_of_key_not_clustered()
  Create column bitmaps in TABLE and TABLE_SHARE
  Don't setup a temporary MEM_ROOT object as a thread specific variable for the handler. Instead we send the to-be-used MEMROOT to get_new_handler()
  Update to new handler interface
  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()
  - st_table::mark_columns_needed_for_update()
  - st_table::mark_columns_needed_for_insert()
sql/table.h:
  Moved column usage bitmaps from handler to TABLE
  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().

f4781a7e4c fix for bug #17619 Scheduler race conditions
- Scheduler is either initialized at server start or never.
  Starting & stopping is now suspending & resuming.
- The scheduler has clear OO interface
- Now all calls to the scheduler are synchronous
- GLOBAL event_scheduler uses thd::sys_var_tmp (see set_var.cc)
- External API is encapsulated into class Events
- Includes fixes for all comments of Kostja's review of 19.05.2005

Starting to merge into 5.1-release (5.1.10) and push

    to use the new class Event_scheduler.
sql/event.h:
  - add COND_finished so if one thread kills a running event it waits on this
  - export callback event_timed_definer_equal, event_timed_identifier_equal(),
    event_timed_name_equal and event_timed_db_equal()
    to be used by Event_scheduler::drop_matching_events()
  - cleanup event.h

  - fix calculation of time when ENDS is set (STARTS is always set)
  - during Event_timed::compile() set the right Security_ctx. Prevents a crash
        during Event_scheduler::load_events_from_db()
  - add Event_timed::kill_thread()
  - implement event_timed_*_equal()
  - made change_security_context() and restore_security_context() free functions.
  - Comments cleanups

  move these from event_scheduler.cc
sql/mysql_priv.h:
  refactor kill_one_thread
  export sql_print_message_func and sql_print_message_handlers
sql/mysqld.cc:
  In close_connections, called by kill_server() skip the main scheduler
  thread and use events_shutdown() for shutting down the scheduler, in the same
  manner it's done for RPL.
  Add a new value to --event-scheduler :
  0 <- No scheduler available
  1 <- Start with scheduler enabled
  2 <- Start with scheduler suspended
sql/repl_failsafe.cc:
  refactor thd::system_thread to be an enum
sql/set_var.cc:
  move sys_var_event_executor::update() to set_var.cc
  executor -> scheduler
  use thd::sys_var_tmp

  for debug purposes.
sql/sql_parse.cc:
  refactor kill_one_thread() -> does the *dirty* work, and sql_kill
  just the reporting.

c06972bf2a Bug #1039: tmpdir and datadir not available via @@ system variable syntax
Bug #19606: ssl variables are not displayed in show variables
Bug #19616: log_queries_not_using_indexes  is not listed in show variables

  Make basedir, datadir, tmpdir, log_queries_not_using_indexes, ssl_ca,
  ssl_capath, ssl_cert, ssl_cipher, and ssl_key all available both from
  SHOW VARIABLES and as @@variables.

  As a side-effect of this change, log_queries_not_using_indexes can
  be changed at runtime (but only globally, not per-connection).

sql/set_var.cc:
  Handle basedir, datadir, tmpdir, log_queries_not_using_indexes, and
  various ssl settings so that they are accessible as server variables
  and listed in SHOW VARIABLES.
sql/set_var.h:
  Add new sys_var_constr_str_ptr class, for when we have a system variable
  that is only set via the command-line that is a pointer to a string.

  Added the appropriate information as read-only system variables, and

5b5530daa5 A fix and a test case for Bug#16365 "Prepared Statements: DoS with
too many open statements". The patch adds a new global variable
@@max_prepared_stmt_count. This variable limits the total number
of prepared statements in the server. The default value of
@@max_prepared_stmt_count is 16382. 16382 small statements
(a select against 3 tables with GROUP, ORDER and LIMIT) consume 
100MB of RAM. Once this limit has been reached, the server will 
refuse to prepare a new statement and return ER_UNKNOWN_ERROR 
(unfortunately, we can't add new errors to 4.1 without breaking 5.0). The limit is changeable after startup
and can accept any value from 0 to 1 million. In case
the new value of the limit is less than the current
statement count, no new statements can be added, while the old
still can be used. Additionally, the current count of prepared 
statements is now available through a global read-only variable 
@@prepared_stmt_count.

  with a lock.

  New declarations to add support for @@max_prepared_stmt_count.
  Implement a new class, where the lock to be used when updating
  a variable is a parameter.

59eaf292de Fixed compiler and valgrind warnings
Added missing DBUG_xxx_RETURN statements
Fixed some usage of not initialized variables (as found by valgrind)
Ensure that we don't remove locked tables used as name locks from open table cache until unlock_table_names() are called.
This was fixed by having drop_locked_name() returning any table used as a name lock so that we can free it in unlock_table_names()

b9f6f9bc64 Fixes to the replication mixed mode (patch approved by Monty):
- detect the need for row-based binlogging not at execution stage but earlier at parsing stage; needed for example for CREATE TABLE SELECT UUID().
- more tests of this mixed mode.


mysql-test/r/rpl_switch_stm_row_mixed.result:
  result update
mysql-test/t/rpl_switch_stm_row_mixed.test:
  testing more scenarios for the mixed replication mode.
  Added support for manual testing of UDFs vs the mixed mode (behind a variable in the test).
  Changing old file names to better ones.
sql/item_create.cc:
  at parse time, when we see a UUID(), put up a flag in LEX to say this binlogs properly only with row-based binlogging.
sql/item_func.cc:
  it's not perfect to put up the flag at this execution stage, better do it at parse stage.
sql/item_strfunc.cc:
  it's not perfect to put up the flag at this execution stage, better do it at parse stage
sql/set_var.cc:
  this assertion is wrong, this piece of code can happen in RBR mode too.
sql/sql_lex.cc:
  when we reinitialize the LEX members before every query, we have to reinitialize the new flag
sql/sql_lex.h:
  A new flag, set at parsing stage, which tells if some items seen during parsing stage require row-based replication to binlog/replicate correctly
  when this statement is later executed.
  It has to be in LEX and not directly in THD, for this to work in prepared statements.
sql/sql_parse.cc:
  Parsing stage happened at some time in the past and set up the flag in LEX, now that we execute the statement we actually turn on row-based binlogging
  if the thread's binlog format is "mixed". We then turn it off when leaving mysql_execute_command().
  Some cleanup code was not executed if leaving mysql_execute_command() at the "error" label, fixing this. A better fix than the "goto end" would be
  to modify each "goto error" to "res=1; goto end" but it required changing many lines which I don't want to do now ("make smallest possible patch").
sql/sql_yacc.yy:
  When at parsing stage we see a UDF we put up a flag to say that row-based binlogging is preferred.

7cac0ddfd0 WL#2977 and WL#2712 global and session-level variable to set the binlog format (row/statement),
and new binlog format called "mixed" (which is statement-based except if only row-based is correct,
in this cset it means if UDF or UUID is used; more cases could be added in later 5.1 release):
SET GLOBAL|SESSION BINLOG_FORMAT=row|statement|mixed|default;
the global default is statement unless cluster is enabled (then it's row) as in 5.1-alpha.
It's not possible to use SET on this variable if a session is currently in row-based mode and has open temporary tables (because CREATE
TEMPORARY TABLE was not binlogged so temp table is not known on slave),  or if NDB is enabled (because
NDB does not support such change on-the-fly, though it will later), of if in a stored function (see below).
The added tests test the possibility or impossibility to SET, their effects, and the mixed mode,
including in prepared statements and in stored procedures and functions.
Caveats:
a) The mixed mode will not work for stored functions: in mixed mode, a stored function will
always be binlogged as one call and in a statement-based way (e.g. INSERT VALUES(myfunc()) or SELECT myfunc()).
b) for the same reason, changing the thread's binlog format inside a stored function is
refused with an error message.
c) the same problems apply to triggers; implementing b) for triggers will be done later (will ask
Dmitri).
Additionally, as the binlog format is now changeable by each user for his session, I remove the implication
which was done at startup, where row-based automatically set log-bin-trust-routine-creators to 1
(not possible anymore as a user can now switch to stmt-based and do nasty things again), and automatically
set --innodb-locks-unsafe-for-binlog to 1 (was anyway theoretically incorrect as it disabled
phantom protection).
Plus fixes for compiler warnings.

8dc567dbed Fix for BUG#13897 "failure to do SET SQL_MODE=N where N is a number > 31" (the original bug's title isn't the simplest
symptom). sys_var::check_set() was wrong. mysqlbinlog makes use of such SET SQL_MODE=N
(where N is interpreted like if SQL_MODE was a field of type SET), so
this bug affected recovery from binlogs if the server was running with certain SQL_MODE values,
for example the default values on Windows (STRICT_TRANS_TABLES); to work around this bug people
had to edit mysqlbinlog's output.
