76fa1d4381 Fixing problems I identified in my auto_increment work pushed in July 
(as part of the auto_increment cleanup of WL#3146; let's not be
sad, that monster push still removed serious bugs):
one problem with INSERT DELAYED (unexpected interval releases),
one with stored functions (wrong auto_inc binlogging).
These bugs were not released.


mysql-test/extra/binlog_tests/binlog_insert_delayed.test:
      more tests of binlogging of INSERT DELAYED: with multi-row INSERTs.
      I identified why sleeps are needed to get a repeatable row-based
      binlogged: because without sleeps rows sometimes get groupped
      and so generate different row based events.
mysql-test/extra/rpl_tests/rpl_foreign_key.test:
  don't forget to drop tables on slave too, otherwise it leaves
  an orphan innodb table leading to rpl_insert_id failing sometimes
  (like in pushbuild "sapsrv2 -max").
mysql-test/extra/rpl_tests/rpl_insert_id.test:
      testing that if some statement does not update any row, it does
      not pollute the auto_inc binlog variables of the next statement;
      the test has to use stored procedures because with plain statements,
      mysql_reset_thd_for_next_command() does the resetting (and thus
      there is no problem); mysql_reset_thd_for_next_command() is not
      called inside routines.
mysql-test/r/binlog_row_binlog.result:
  result additions
mysql-test/r/binlog_statement_insert_delayed.result:
  result additions
mysql-test/r/binlog_stm_binlog.result:
  result additions
mysql-test/r/rpl_insert_id.result:
  result additions
mysql-test/r/rpl_loaddata.result:
      With the change to log.cc reverted, the result changes and is better:
      the change to log.cc had caused some INSERT_ID events to disappear
      though they were necessary (but testsuite could not catch that because
      it's single-threaded).
mysql-test/r/rpl_ndb_insert_ignore.result:
  NDB is now like other engines regarding INSERT IGNORE: autoincrement
  values which caused a duplicate key are re-used for next row, not lost.
  rpl_ndb_insert_ignore.result is now identical to rpl_insert_ignore.result.
sql/log.cc:
      LOAD DATA INFILE is binlogged as several events, and the last of them must
      have the auto_inc id. So it's wrong to reset the auto_inc id after every
      binlog write (because then it's lost after the first event of LOAD
      DATA INFILE and so missing for the last one)/
      Another problem: MYSQL_LOG::write() is not always called (for example
      if no row was updated), so we were missing reset in some cases.
sql/sp_head.cc:
      SELECT func1(),func2() generates two binlog events, so needs to
      clear auto_increment binlog variables after each binlog event
      (it would be more natural to clear them in the log write code,
      but LOAD DATA INFILE would suffer from this see the cset comment
      for log.cc). Without the clearing, the problem is:
      > exec func1()
      >> call cleanup_after_query() (which does not clear our vars here)
      >> binlog SELECT func1()
      <
      > exec func2()
      and so SELECT func2() is binlogged with the auto_inc of SELECT func1().
sql/sql_class.cc:
      after every statement we should clear auto_inc variables used for
      binlogging, except if this was a function/trigger (in which case
      it may be "INSERT SELECT func()", where the cleanup_after_query()
      executed in func() should not reset the auto_inc binlog variables
      as they'll be necessary when binlogging the INSERT SELECT later).
sql/sql_insert.cc:
      - as INSERT DELAYED uses the same TABLE object as the delayed_insert
      system thread, we should not call ha_release_auto_increment()
      from INSERT DELAYED (and btw it's logical as we reserve nothing
      as we don't perform the insert). Calling the function caused us to
      release values being used by the delayed_insert thread.
      So I do the call only if this is a non-DELAYED INSERT.
      - Assuming two INSERT DELAYED which get grouped by the delayed_insert
      thread, the second may use values reserved by the first, which is ok
      per se, but is a problem in statement-based binlogging:
      the 2nd INSERT gets binlogged with the "interval start" value
      of the first INSERT (=> duplicate error in slave).
      - no reason to ha_release_auto_increment() after every inserted row
      in INSERT SELECT; more efficient to do it only when the statement ends

133d2aa599 Fix for bug#21795: SP: sp_head::is_not_allowed_in_function() contains 
erroneous check

Problem: Actually there were two problems in the server code. The check
for SQLCOM_FLUSH in SF/Triggers were not according to the existing
architecture which uses sp_get_flags_for_command() from sp_head.cc .
This function was also missing a check for SQLCOM_FLUSH which has a
problem combined with prelocking. This changeset fixes both of these
deficiencies as well as the erroneous check in
sp_head::is_not_allowed_in_function() which was a copy&paste error.


mysql-test/r/sp-error.result:
  update result
mysql-test/r/trigger.result:
  update result
mysql-test/t/sp-error.test:
  FLUSH can create a problem with prelocking, hence it's disabled.
  There is a better way to check this than a check in the parser.
  Now we use sp_get_flags_for_command() and the error returned is
  different.
mysql-test/t/trigger.test:
  FLUSH can create a problem with prelocking, hence it's disabled.
  There is a better way to check this than a check in the parser.
  Now we use sp_get_flags_for_command() and the error returned is
  different.
sql/sp_head.cc:
  FLUSH and RESET are not allowed inside a SF/Trigger.
  Because they don't imply a COMMIT sp_head::HAS_COMMIT_OR_ROLLBACK
  cannot be used. Two new flags were introduced for that reason.
sql/sp_head.h:
  Don't check m_type as this check is erroneous. This is probably
  a copy and paste error when moving code from somewhere else. Another
  fact which supports this was prefixing the enum value with the name
  of class sp_head.
  
  Adding two new flags HAS_SQLCOM_RESET and HAS_SQLCOM_FLUSH. The values
  are 2048 and 4096 because in the 5.1 branch there are already new flags
  which are with values up-to 1024.
sql/sql_parse.cc:
  FLUSH can cause a problem with prelocking in SF/Trigger and
  therefore is already disabled. RESET is also disabled because
  is handled by the same code as FLUSH. We won't allow RESET inside
  SF/Trigger at that stage without thorough analysis. The check for
  them is already done in the parser by calling
  is_not_allowed_in_function()
sql/sql_yacc.yy:
  By listing SQLCOM_FLUSH as command which implies COMMIT
  in sp_get_flags_for_command() the check in sql_yacc.yy is
  obsolete.

7a37eeae62 Fix for bug #20665 All commands supported in Stored Procedures 
should work in Prepared Statements. Post-review changeset.

Problem: There are some commands which are avaiable to be executed in SP
         but cannot be prepared. This patch fixes this and makes it possible
         prepare these statements.

Changes: The commands later are made available in PS. RESET has been forbidden
         in SF/Trigger.

Solution: All current server commands where checked and those missing (see later)
          we added. Tests for all of the commands with repeated executions were
          added - testing with SP, SF and PS.

  This cleanup is present in 5.1 only, but the test that was added in 
  5.0 assumes there is a current database, test.
mysql-test/r/mysqldump.result:
  Ignore results of execution of mysqldump: we can't rely on 
  MASTER_LOG_POS in test results, it's different for statement
  and row level logging.

  the test case for Bug#19862 in the test suite).
mysql-test/r/strict.result:
  An after-merge fix for a new test case: in 5.1 we issue a more accurate
  error message: "Incorrect value" instead of "Truncated value". I reason
  it so that in case of an error nothing is truncated, really.
  Also found similar changes in other test cases.
mysql-test/r/type_datetime.result:
  Fix the text of an error.
mysql-test/r/union.result:
  A post-merge fix: CHARACTER SET is now uppercase.
mysql-test/t/mysqlcheck.test:

  is no current database.
mysql-test/t/mysqldump.test:
  Disable result log: it's dependent on binlog position.
mysql-test/t/sp-security.test:
  use test
sql/item_sum.cc:
  Adjust the call to the constructor after the merge.
sql/sp_head.cc:
  Add a missing DBUG_VOID_RETURN, move security checks out of
  execute_trigger to Table_triggers_list: in 5.1 we check for
  TRIGGER privilege, not SUPER privilege to execute triggers, so these
  checks lack table context inside execute_trigger and have to be
  performed when we have table object on hand.
sql/sql_db.cc:
  A post-merge fix: adjust load_db_opt_by_name and check_db_dir_existence
  (new functions added in 5.0) to be tablename-to-filename encoding 
  friendly.

d36f578130 Fix for BUG#20438: CREATE statements for views, stored routines and triggers 
can be not replicable.

Now CREATE statements for writing in the binlog are created as follows:
  - the beginning of the statement is re-created;
  - the rest of the statement is copied from the original query.

The problem appears when there is a version-specific comment (produced by
mysqldump), started in the re-created part of the statement and closed in the
copied part -- there is closing comment-parenthesis, but there is no opening
one.

The proper fix could be to re-create original statement, but we can not
implement it in 5.0. So, for 5.0 the fix is just to cut closing
comment-parenthesis. This technique is also used for SHOW CREATE PROCEDURE

3c10858474 Fix for BUG#16211: Stored function return type for strings is ignored. 
Fix for BUG#16676: Database CHARSET not used for stored procedures

The problem in BUG#16211 is that CHARSET-clause of the return type for
stored functions is just ignored.

The problem in BUG#16676 is that if character set is not explicitly
specified for sp-variable, the server character set is used instead
of the database one.

The fix has two parts:

  - always store CHARSET-clause of the return type along with the
    type definition in mysql.proc.returns column. "Always" means that
    CHARSET-clause is appended even if it has not been explicitly
    specified in CREATE FUNCTION statement (this affects BUG#16211 only).

    Storing CHARSET-clause if it is not specified is essential to avoid
    changing character set if the database character set is altered in
    the future.

    NOTE: this change is not backward compatible with the previous releases.

  - use database default character set if CHARSET-clause is not explicitly
    specified (this affects both BUG#16211 and BUG#16676).

    NOTE: this also breaks backward compatibility.

06bf59ad33 Bug#18630: Arguments of suid routine calculated in wrong security 
context.

Routine arguments were evaluated in the security context of the routine
itself, not in the caller's context.

The bug is fixed the following way:

  - Item_func_sp::find_and_check_access() has been split into two
    functions: Item_func_sp::find_and_check_access() itself only
    finds the function and check that the caller have EXECUTE privilege
    on it.  New function set_routine_security_ctx() changes security
    context for SUID routines and checks that definer have EXECUTE
    privilege too.

  - new function sp_head::execute_trigger() is called from
    Table_triggers_list::process_triggers() instead of
    sp_head::execute_function(), and is effectively just as the
    sp_head::execute_function() is, with all non-trigger related code
    removed, and added trigger-specific security context switch.

  - call to Item_func_sp::find_and_check_access() stays outside
    of sp_head::execute_function(), and there is a code in
    sql_parse.cc before the call to sp_head::execute_procedure() that
    checks that the caller have EXECUTE privilege, but both
    sp_head::execute_function() and sp_head::execute_procedure() call
    set_routine_security_ctx() after evaluating their parameters,
    and restore the context after the body is executed.

81a80049aa * Mixed replication mode * : 
1) Fix for BUG#19630 "stored function inserting into two auto_increment breaks
statement-based binlog":
a stored function inserting into two such tables may fail to replicate
(inserting wrong data in the slave's copy of the second table) if the slave's
second table had an internal auto_increment counter different from master's.
Because the auto_increment value autogenerated by master for the 2nd table
does not go into binlog, only the first does, so the slave lacks information.
To fix this, if running in mixed binlogging mode, if the stored function or
trigger plans to update two different tables both having auto_increment
columns, we switch to row-based for the whole function.
We don't have a simple solution for statement-based binlogging mode, there
the bug remains and will be documented as a known problem.
Re-enabling rpl_switch_stm_row_mixed.
2) Fix for BUG#20630 "Mixed binlogging mode does not work with stored
functions, triggers, views", which was a documented limitation (in mixed
mode, we didn't detect that a stored function's execution needed row-based
binlogging (due to some UUID() call for example); same for
triggers, same for views (a view created from a SELECT UUID(), and doing
INSERT INTO sometable SELECT theview; would not replicate row-based).
This is implemented by, after parsing a routine's body, remembering in sp_head
that this routine needs row-based binlogging. Then when this routine is used,
the caller is marked to require row-based binlogging too.
Same for views: when we parse a view and detect that its SELECT needs
row-based binary logging, we mark the calling LEX as such.
3) Fix for BUG#20499 "mixed mode with temporary table breaks binlog":
a temporary table containing e.g. UUID has its changes not binlogged,
so any query updating a permanent table with data from the temporary table
will run wrongly on slave. Solution: in mixed mode we don't switch back
from row-based to statement-based when there exists temporary tables.
4) Attempt to test mysqlbinlog on a binlog generated by mysqlbinlog;
impossible due to BUG#11312 and BUG#20329, but test is in place for when
they are fixed.

  and triggers.
sql/sp_head.cc:

  routine, we found at least one element (UUID(), UDF) requiring row-based
  binlogging.
sql/sp_head.h:
  new enum value for sp_head::m_flags (see sp_head.cc).
  An utility method, intended for attributes of a routine which need
  to propagate upwards to the caller; so far only used for binlogging
  information, but open to any other attribute.
sql/sql_base.cc:
  For BUG#19630 "stored function inserting into two auto_increment
  breaks statement-based binlog":
  When we come to locking tables, we have collected all tables used by
  functions, views and triggers, we detect if we're going to update two tables
  having auto_increment columns. If yes, statement-based binlogging won't work
  (Intvar_log_event records only one insert_id) so, if in mixed binlogging
  mode, switch to row-based.
  For making mixed mode work with stored functions using UUID/UDF:
  when we come to locking tables, we have parsed the whole body so know if
  some elements need row-based. Generation of row-based binlog events
  depends on locked tables, so this is the good place to decide of the binlog
  format.
sql/sql_class.h:
  Fix for BUG#20499 "mixed mode with temporary table breaks binlog".
  Making mixed mode work with stored functions/triggers: don't reset
  back to statement-based if in executing a stored function/trigger.
sql/sql_lex.cc:
  fix for build without row-based replication.
  binlog_row_based_if_mixed moves from st_lex to Query_tables_list, because
  that boolean should not be affected when a SELECT reads the INFORMATION_SCHEMA
  and thus implicitely parses a view or routine's body: this body may
  contain needing-row-based components like UUID() but the SELECT on
  INFORMATION_SCHEMA should not be affected by that and should not use
  row-based; as Query_tables_list is backed-up/reset/restored when parsing
  the view/routine's body, so does binlog_row_based_if_mixed and the
  top SELECT is not affected.
sql/sql_lex.h:
  fix for build without row-based replication.
  binlog_row_based_if_mixed moves from st_lex to Query_tables_list
  (see sql_lex.cc)
sql/sql_parse.cc:
  For the mixed mode to work with stored functions using UUID and UDF, we need
  to move the switch-back-from-row-to-statement out of
  mysql_execute_command() (which is executed for each statement, causing
  the binlogging mode to change in the middle of the function, which would
  not work)
  The switch to row-based is now done in lock_tables(), no need to keep it
  in mysql_execute_command(); in lock_tables() we also switch back from 
  row-based to statement-based (so in a stored procedure, all statements
  have their binlogging mode). We must however keep a resetting in
  mysql_reset_thd_for_next_command() as e.g. CREATE PROCEDURE does not call
  lock_tables().
sql/sql_view.cc:
  When a view's body needs row-based binlogging (e.g. the view is created
  from SELECT UUID()), propagate this fact to the top st_lex.
sql/sql_yacc.yy:
  use TRUE instead of 1, for binlog_row_based_if_mixed.

d6bcbfbe92 A fix and a test case for 
Bug#19022 "Memory bug when switching db during trigger execution"
 Bug#17199 "Problem when view calls function from another database."
 Bug#18444 "Fully qualified stored function names don't work correctly in
            SELECT statements"

 Documentation note: this patch introduces a change in behaviour of prepared
 statements.

 This patch adds a few new invariants with regard to how THD::db should
 be used. These invariants should be preserved in future:

  - one should never refer to THD::db by pointer and always make a deep copy
    (strmake, strdup)
  - one should never compare two databases by pointer, but use strncmp or
    my_strncasecmp
  - TABLE_LIST object table->db should be always initialized in the parser or
    by creator of the object.

    For prepared statements it means that if the current database is changed
    after a statement is prepared, the database that was current at prepare
    remains active. This also means that you can not prepare a statement that
    implicitly refers to the current database if the latter is not set.
    This is not documented, and therefore needs documentation. This is NOT a
    change in behavior for almost all SQL statements except:
     - ALTER TABLE t1 RENAME t2 
     - OPTIMIZE TABLE t1
     - ANALYZE TABLE t1
     - TRUNCATE TABLE t1 --
     until this patch t1 or t2 could be evaluated at the first execution of
     prepared statement. 

     CURRENT_DATABASE() still works OK and is evaluated at every execution
     of prepared statement.

     Note, that in stored routines this is not an issue as the default
     database is the database of the stored procedure and "use" statement
     is prohibited in stored routines.

  This patch makes obsolete the use of check_db_used (it was never used in the
  old code too) and all other places that check for table->db and assign it
  from THD::db if it's NULL, except the parser.

 How this patch was created: THD::{db,db_length} were replaced with a
 LEX_STRING, THD::db. All the places that refer to THD::{db,db_length} were
 manually checked and:
  - if the place uses thd->db by pointer, it was fixed to make a deep copy
  - if a place compared two db pointers, it was fixed to compare them by value
    (via strcmp/my_strcasecmp, whatever was approproate)
 Then this intermediate patch was used to write a smaller patch that does the
 same thing but without a rename.

 TODO in 5.1:
   - remove check_db_used
   - deploy THD::set_db in mysql_change_db

67fd3c4a53 A fix and a test case for Bug#15217 "Using a SP cursor on a table created 
with PREPARE fails with weird error".
More generally, re-executing a stored procedure with a complex SP cursor query
could lead to a crash.

The cause of the problem was that SP cursor queries were not optimized 
properly at first execution: their parse tree belongs to sp_instr_cpush,
not sp_instr_copen, and thus the tree was tagged "EXECUTED" when the
cursor was declared, not when it was opened. This led to loss of optimization
transformations performed at first execution, as sp_instr_copen saw that the
query is already "EXECUTED" and therefore either not ran first-execution 
related blocks or wrongly rolled back the transformations caused by 
first-execution code.
The fix is to update the state of the parsed tree only when the tree is
executed, as opposed to when the instruction containing the tree is executed.
Assignment if i->state is moved to reset_lex_and_exec_core.

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.

mysys/base64.c:
  Include my_global.h first
mysys/my_bitmap.c:
  Added bitmap_is_overlapping(), bitmap_test_and_clear() and bitmap_copy()
  Changed logic of bitmap handling to be a bit more efficent (Did this together with Mikael Ronström)
  Now the 'extra, not used bits' in the bitmap are assumed to have a 'random value' and the bitmap functions are free to change them whenever needed.
  Changed how mutex is allocated to make 'bitmap_free()' function simpler.
mysys/thr_lock.c:
  Added 0x before thread pointers (for easier comparison of DBUG traces)
sql/event.cc:

  Removed Field->fieldnr (use Field->field_index instead)
  Removed Field->add_index (Use Field->flags instead)
  Add Field->part_of_key_not_clustered (for usage in opt_range.cc)
sql/filesort.cc:
  Added paramater sort_postion to filesort() to force sorting by position instead of storing all fields in the result set.
  This allowed me to remove checking of sql_command.
  Create a temporary column bitmap for fields that are used by the sorting process.
  Use column bitmaps instead of query_id
sql/ha_berkeley.cc:
  Update to 'newer' table handler interface
sql/ha_berkeley.h:
  Update to 'newer' table handler interface

  Use 'simpler to use' XXXX_LEN' macros
  A bit simpler logic in ::write_row() when creating statements.
  In update, only include test of fields actually read.
  (This greatly simplifies the queries sent by the federated engine)

  - Renamed HA_PRIMARY_KEY_ALLOW_RANDOM_ACCESS to HA_PRIMARY_KEY_REQUIRED_FOR_POSITION.
  - Prefixed base status variables with 'stats'
  - Use table column bitmaps instead of ha_get_bit_in_read_set()
  - Added ::reset(), with code from ::extra(HA_EXTRA_RESET)
  - Removed HA_EXTRA_RETRIVE_ALL_COLS and HA_EXTRA_RETRIEVE_PRIMARY_KEY as
    the table->read_set and table->write_set bitmaps now are accurate
sql/ha_innodb.h:
  Update to 'newer' table handler interface
  - table_flags are now ulonglong
  - Added reset() method

sql/ha_partition.cc:
  Update to 'newer' table handler interface
  Added memroot to initialise_partitions() and related functions to get faster memory allocation.
  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 ha_reset() function to test that the file object is ok at end of statement and call handler::reset()
  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

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

  (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

  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)

  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

  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()
  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().
sql/tztime.cc:
  Mark all columns as used for timezone tables

sql/item.h:
  Add interface class Settable_routine_parameter and interface query
  method to Item class.  Item_splocal and Item_trigger_field implement

59ff52747d Fix for bug #17260 "Multiple invocations of triggers or stored functions 
hog memory".

During each invocation of stored function or trigger some objects which
lifetime is one function call (e.g. sp_rcontext) were allocated on
arena/memroot of calling statement. This led to consumption of fixed amount
of memory for each function/trigger invocation and so statements which
involve lot of them were hogging memory. This in its return led to OOM
crashes or freezes.

This fix introduces new memroot and arena for objects which lifetime is
whole duration of function call. So all memory consumed by such objects
is freed at the end of function call.


sql/sp_head.cc:
  sp_head::execute_function():
    Introduced new memroot and arena for objects which lifetime is whole
    duration of function call (e.g. sp_rcontext, sp_cursor). We can't
    use caller's arena/memroot for those objects because in this case 
    some fixed amount of memory will be consumed for each function/trigger
    invocation and so statements which involve lot of them will hog memory.
    Got rid of param_values array to avoid excessive juggling with arenas.

661165ee10 Fixed BUG#18949: Test case sp-goto is disabled 
Removed sp-goto.test, sp-goto.result and all (disabled) GOTO code.
  Also removed some related code that's not needed any more (no possible
  unresolved label references any more, so no need to check for them).
  NB: Keeping the ER_SP_GOTO_IN_HNDLR in errmsg.txt; it might become useful
      in the future, and removing it (and thus re-enumerating error codes)
      might upset things. (Anything referring to explicit error codes.)
