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).

Added MEM_ROOT to handlerton 'create' function
Added ha_statistics, a structure for all status variable in the base handler class.
Moved all status variables in the handler class into a stats structs to improve readability.
ha_table_flags() is now a cached (not virtual) version of table_flags()
reset() doesn't anymore call extra(HA_EXTRA_RESET) but is a function of it's own.
Renamed dupp_ref to dup_ref
Renamed not used handler::sortkey
Moved read_set and write_set to TABLE structure
handler::init() function added for cacheing of virtual constants from engine.
sql/item.cc:

Ensured that second argument to trans_register_ha is a bool
sql/log_event.cc:
Fixed comments to be withing 79 characters
Use OPTION_KEEP_LOG instead of OPTION_STATUS_NO_TRANS_UPDATE to remove wrong warnings
Updates for new handler interface
Use 0x%lx instead of %p (portability problem)
sql/mysql_priv.h:
Added OPTION_KEEP_LOG to indicate that we should replicate the binlog even on rollback
Removed not used 'conds' argument to setup_tables
sql/mysqld.cc:
Indentation fixes and removed old comment
sql/opt_range.cc:
Update to new handler and bitmap interface.
Fixed calls to cp_buffer_from_ref() and walk() (new argument).
Create new temporary bitmaps for ror scans.
(Needed because of handler changes and to get more accurate column bitmaps than before)
Remove not needed file->ha_reset() call before file->close().
Some trivial optimization and indentation fixes.
Use Field->part_of_key_not_clustered() to check if field is part of a key, instead of looping over all key parts.
Added flag 'in_ror_merged_scan' to allow ::get_next() to know that we need a special column bitmap to only fetch pointer to record.
This is needed because ror scan uses the same TABLE object but different file objects, which creates problem for the column bitmap handling.
(This is a temporary solution. A better one would be to allocate an own TABLE object for ROR scans)
Optimized bitmap handling in ror scans:
- Start bitmap at position 0, not 1
- Use same bitmap size as in TABLE
- Use table->read_set and table->write_set to create column bitmaps instead of looping over all fields in table
sql/opt_range.h:
Added 'in_ror_merged_scan' to indicate if we are doing a ROR scan
Added temporary column bitmaps used in ROR scans
sql/opt_sum.cc:
Added get_ext_record_count() which is used in COUNT() optimization if handler has HA_HAS_RECORDS
Note that we don't call this if handler has HA_STATS_RECORDS_IS_EXACT set.
sql/protocol.cc:
We need to mark columns as readable in ::store() as we sometimes return default value for fields to the user

sql/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

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

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

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().

Fixed bug#14169: type of group_concat() result changed to blob if tmp_table was
used In a simple queries a result of the GROUP_CONCAT() function was always of varchar type. But if length of GROUP_CONCAT() result is greater than 512 chars and temporary table is used during select then the result is converted to blob, due to policy to not to store fields longer than 512 chars in tmp table as varchar fields. In order to provide consistent behaviour, result of GROUP_CONCAT() now will always be converted to blob if it is longer than 512 chars. Item_func_group_concat::field_type() is modified accordingly. mysql-test/t/func_gconcat.test: Added test case for bug#14169: type of group_concat() result changed to blob if tmp_table was used mysql-test/r/func_gconcat.result: Added test case for bug#14169: type of group_concat() result changed to blob if tmp_table was used sql/unireg.h: Added the CONVERT_IF_BIGGER_TO_BLOB constant sql/sql_select.cc: Fixed bug#14169: type of group_concat() result changed to blob if tmp_table was used The unnamed constant 255 in the create_tmp_field() and create_tmp_field_from_item() functions now defined as the CONVERT_IF_BIGGER_TO_BLOB constant.

Fixed bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries
The GROUP_CONCAT uses its own temporary table. When ROLLUP is present it creates the second copy of Item_func_group_concat. This copy receives the same list of arguments that original group_concat does. When the copy is set up the result_fields of functions from the argument list are reset to the temporary table of this copy. As a result of this action data from functions flow directly to the ROLLUP copy and the original group_concat functions shows wrong result. Since queries with COUNT(DISTINCT ...) use temporary tables to store the results the COUNT function they are also affected by this bug. The idea of the fix is to copy content of the result_field for the function under GROUP_CONCAT/COUNT from the first temporary table to the second one, rather than setting result_field to point to the second temporary table. To achieve this goal force_copy_fields flag is added to Item_func_group_concat and Item_sum_count_distinct classes. This flag is initialized to 0 and set to 1 into the make_unique() member function of both classes. To the TMP_TABLE_PARAM structure is modified to include the similar flag as well. The create_tmp_table() function passes that flag to create_tmp_field(). When the flag is set the create_tmp_field() function will set result_field as a source field and will not reset that result field to newly created field for Item_func_result_field and its descendants. Due to this there will be created copy func to copy data from old result_field to newly created field. mysql-test/t/func_gconcat.test: Added test for bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries mysql-test/r/func_gconcat.result: Added test for bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries sql/sql_table.cc: Fixed bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries Added 0 as a last parameter to create_tmp_field() to force old behaviour. sql/sql_select.cc: Fixed bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries Added the flag 'make_copy_field' to create_tmp_field(), so that for Item_result_field descendants create_tmp_field() sets the item's result field as a source field and deny resetting that result field to a new value. sql/sql_class.h: Fixed bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries Added the flag 'force_copy_fields' to the structure TMP_TABLE_PARAM in order to make create_tmp_field() force the creation of 'copy_field' objects. sql/mysql_priv.h: Fixed bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries Added the bool parameter 'make_copy_field' to create_tmp_field(). sql/item_sum.cc: Fixed bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries Added initialization of the force_copy_fields flag and passing it to create_tmp_table() through TMP_TBLE_PARAM in the Item_func_group_concat and Item_sum_count_distinct member functions. sql/item_sum.h: Fixed bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries Added the flag 'force_copy_fields' to the Item_func_group_concat and Item_sum_count_distinct classes. |

Fix for Bug #9913 "udf_deinit is not called after execution of PS"
(aka "deinit is not called when calling udf from trigger"). We should call udf_deinit() function during cleanup phase after prepared (or ordinary) statement execution instead of calling it from Item's desctructor. No test case is provided since it is hard to test UDF's from our test suite. sql/item_func.cc: udf_handler: Moved all functionality from udf_handler::~udf_handler() to udf_handler::cleanup() method which will be called after each PS execution, thus allowing udf_deinit() to be executed symetrically with udf_init() (which is executed for each execution of PS). Added Item_udf_func::cleanup() which performs proper cleanup after execution of PS with UDF function. sql/item_func.h: Added Item_udf_func::cleanup() method to perform cleanup properly after execution of PS with UDF function. sql/item_sum.cc: Added Item_udf_sum::cleanup() method to perform cleanup properly after execution of PS with aggregate UDF function. sql/item_sum.h: Added Item_udf_sum::cleanup() method to perform cleanup properly after execution of PS with aggregate UDF function. sql/sql_udf.h: Added udf_handler::cleanup() method declaration which is responsible for cleaning up UDF execution context at the end of execution of statement (using ~udf_handler() for this purprose did not worked for PS). |

Fix for bug#4912 "mysqld crashs in case a statement is executed
a second time". The bug was caused by incompatibility of
negations elimination algorithm and PS: during first statement
execute a subtree with negation was replaced with equivalent
subtree without NOTs.
The problem was that although this transformation was permanent,
items of the new subtree were created in execute-local memory.
The patch adds means to check if it is the first execute of a
prepared statement, and if this is the case, to allocate items
in memory of the prepared statement.
The implementation:
- backports Item_arena from 5.0
- adds Item_arena::is_stmt_prepare(),
Item_arena::is_first_stmt_execute().
- deletes THD::allocate_temporary_pool_for_ps_preparing(),
THD::free_temporary_pool_for_ps_preparing(); they
were redundant.
and adds a few invariants:
- thd->free_list never contains junk (= freed items)
- thd->current_arena is never null. If there is no
prepared statement, it points at the thd.
The rest of the patch contains mainly mechanical changes and
cleanups.

A test case for Bug#4912 "mysqld crashs in case a statement is

sql/mysql_priv.h:
Statement -> Item_arena
sql/sql_base.cc:
current_statement -> current_arena
sql/sql_class.cc:
- Item_arena
- convenient set_n_backup_statement, restore_backup_statement
(nice idea, Sanja)
sql/sql_class.h:
- Item_arena: backport from 5.0
- allocate_temporary_pool_for_ps_preparing,
free_temporary_pool_for_ps_preparing removed.
sql/sql_derived.cc:
current_statement -> current_arena
sql/sql_lex.cc:
current_statement -> current_arena
sql/sql_parse.cc:
Deploy invariant that thd->free_list never contains junk items
(backport from 5.0).
sql/sql_prepare.cc:
- backporting Item_arena
- no need to allocate_temporary_pool_for_ps_preparing().
sql/sql_select.cc:
Fix for bug#4912 "mysqld crashs in case a statement is
executed a second time": if this is the first execute of
a prepared statement, negation elimination is
done in memory of the prepared statement.
sql/sql_union.cc:
Backporting Item_arena from 5.0.
