Bug#20543 select on information_schema strange warnings, view, different schemas/users
The fix is: if user has privileges to view fields and user has any (insert,select,delete,update) privileges on underlying view then 'show fields' and select from I_S.COLUMNS table are sucsessful. mysql-test/r/information_schema_db.result: Bug#20543 select on information_schema strange warnings, view, different schemas/users test result mysql-test/t/information_schema_db.test: Bug#20543 select on information_schema strange warnings, view, different schemas/users test case sql/sql_acl.cc: Bug#20543 select on information_schema strange warnings, view, different schemas/users checked that user has privileges on underlying view and if it's true set allowed_show to true for top view. sql/sql_show.cc: Bug#20543 select on information_schema strange warnings, view, different schemas/users removed unnecessary rights check.'tables->allowed_show' check is used instead sql/sql_view.cc: Bug#20543 select on information_schema strange warnings, view, different schemas/users skip the check of SHOW_VIEW_ACL privilege on underlying view. It is done later during execution of find_field_in_table_ref function. sql/table.h: Bug#20543 select on information_schema strange warnings, view, different schemas/users 'allowed_show' is set during rights check for view. If true then user has privileges for 'show create view', etc |

* 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. mysql-test/r/rpl_switch_stm_row_mixed.result: testing BUG#19630 "stored function inserting into two auto_increment breaks statement-based binlog", testing BUG#20930 "Mixed binlogging mode does not work with stored functions, triggers, views. testing BUG#20499 "mixed mode with temporary table breaks binlog". I have carefully checked this big result file, it is correct. mysql-test/t/disabled.def: re-enabling test mysql-test/t/rpl_switch_stm_row_mixed.test: Test for BUG#19630 "stored function inserting into two auto_increment breaks statement-based binlog": we test that it goes row-based, but only when needed; without the bugfix, master and slave's data differed. Test for BUG#20499 "mixed mode with temporary table breaks binlog": without the bugfix, slave had 2 rows, not 3. Test for BUG#20930 "Mixed binlogging mode does not work with stored functions, triggers, views". Making strings used more different, for easier tracking of "by which routine was this binlog line generated". Towards the end, an attempt to test mysqlbinlog on a binlog generated by the mixed mode; attempt failed because of BUG#11312 and BUG#20929. sql/item_create.cc: fix for build without row-based replication sql/set_var.cc: cosmetic: in_sub_stmt is exactly meant to say if we are in stored function/trigger, so better use it. sql/sp.cc: When a routine adds its tables to the top statement's tables, if this routine needs row-based binlogging, mark the entire top statement as well. Same for triggers. Needed for making the mixed replication mode work with stored functions and triggers. sql/sp_head.cc: new enum value for sp_head::m_flags, remembers if, when parsing the 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. |

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
See also comments to individual files.
mysql-test/r/create.result:
Modify the result file: a database can never be NULL.
mysql-test/r/ps.result:
Update test results (Bug#17199 et al)
mysql-test/r/sp.result:
Update test results (Bug#17199 et al)
mysql-test/t/create.test:
Update the id of the returned error.
mysql-test/t/ps.test:
Add test coverage for prepared statements and current database. In scope of
work on Bug#17199 "Problem when view calls function from another database."
mysql-test/t/sp.test:
Add a test case for Bug#17199 "Problem when view calls function from another
database." and Bug#18444 "Fully qualified stored function names don't work
correctly in SELECT statements". Test a complementary problem.
sql/item_strfunc.cc:
Touch the code that reads thd->db (cleanup).
sql/log_event.cc:
While we are at it, replace direct access to thd->db with a method.
Should simplify future conversion of THD::db to LEX_STRING.
sql/slave.cc:
While we are at it, replace direct access to thd->db with a method.
Should simplify future conversion of THD::db to LEX_STRING.
sql/slave.h:
Remove a declaration for a method that is used only in one module.
sql/sp.cc:
Rewrite sp_use_new_db: this is a cleanup that I needed in order to understand
this function and ensure that it has no bugs.
sql/sp.h:
Add a new declaration for sp_use_new_db (uses LEX_STRINGs) and a comment.
sql/sp_head.cc:
- drop sp_name_current_db_new - a creator of sp_name class that was used
when sp_name was created for an identifier without an explicitly initialized
database. Now we pass thd->db to constructor of sp_name right in the
parser.
- rewrite sp_head::init_strings: name->m_db is always set now
- use the new variant of sp_use_new_db
- we don't need to update thd->db with SP MEM_ROOT pointer anymore when
parsing a stored procedure, as noone will refer to it (yes!)
sql/sp_head.h:
- remove unneded methods and members
sql/sql_class.h:
- introduce 3 THD methods to work with THD::db:
.set_db to assign the current database
.reset_db to reset the current database (temporarily) or set it to NULL
.opt_copy_db_to - to deep-copy thd->db to a pointer if it's not NULL
sql/sql_db.cc:
While we are at it, replace direct access to thd->db with a method.
Should simplify future conversion of THD::db to LEX_STRING.
sql/sql_insert.cc:
- replace checks with asserts: table_list->db must be always set in the parser.
sql/sql_lex.h:
- add a comment
sql/sql_parse.cc:
- implement the invariant described in the changeset comment.
- remove juggling with lex->sphead in SQLCOM_CREATE_PROCEDURE:
now db_load_routine uses its own LEX object and doesn't damage the main
LEX.
- add DBUG_ASSERT(0) to unused "check_db_used"
sql/sql_table.cc:
- replace a check with an assert (table_ident->db)
sql/sql_trigger.cc:
While we are at it, replace direct access to thd->db with a method.
Should simplify future conversion of THD::db to LEX_STRING.
sql/sql_udf.cc:
- use thd->set_db instead of direct modification of to thd->db
sql/sql_view.cc:
- replace a check with an assert (view->db)
sql/sql_yacc.yy:
- make sure that we always copy table->db or name->db or ident->db or
select_lex->db from thd->db if the former is not set. If thd->db
is not set but is accessed, return an error.
sql/tztime.cc:
- be nice, never copy thd->db by pointer.

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.

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:
Ensure 'use_all_columns()' is used for event tables
Don't print warning that event table is damaged if it doesn't exists.
sql/field.cc:
Added ASSERT_COLUMN_MARKED_FOR_WRITE in all store() methods and ASSERT_COLUMN_MARKED_FOR_READ in all val() methods to catch wrong setting if table->read_set and table->write_set

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.

In case of eq ranges, don't generate two conditions in the WHERE clause
(this can still be optimized, but would require a bigger code change)
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)
Similar changes done for delete_row()
sql/ha_federated.h:
Update to 'newer' table handler interface
Changed XXX_LEN macros to use sizeof(...)-1, to simplify usage in ha_federated.cc
Added HA_PRIMARY_KEY_REQUIRED_FOR_DELETE to tell MySQL to read all primary key columns in case of DELETE
sql/ha_heap.cc:
Update to 'newer' table handler interface

Correct dumping of field data with DBUG_DUMP
Prefix addresses in DBUG_PRINT with 0x
Fixed usage of not initialized memory

Ensure that table_flags() are up to date
Removed documentation for removed HA_EXTRA flags

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

Update Item::walk() to new interface
sql/item_subselect.cc:
Added Item_subselect::walk()
(It was a bug it was missing before. Not sure what kind of bugs this could have caused)
sql/item_subselect.h:
Update Item::walk() to new interface
sql/item_sum.cc:
Update Item::walk() to new interface
Updates for new handler interace
sql/item_sum.h:
Update Item::walk() to new interface

sql/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

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/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_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().

In prepare_view_securety_context() the sql_command came in wrong.
If the first part was SHOW and second part SELECT, it would have thought that the command was SELECT, although the first part of it was SHOW. It would then fail later. Thus we need to set thd->lex to old_lex (first part) here before going in to prepare_security(). |

Fix for bug#15153 "CONVERT_TZ() is not allowed in all places in VIEWs".
Error was emitted when one tried to select information from view which used
merge algorithm and which also had CONVERT_TZ() function in its select list.
This bug was caused by wrong assumption that global table list for view
which is handled using merge algorithm begins from tables belonging to
the main select of this view. Nowadays the above assumption is not true only
when one uses convert_tz() function in view's select list, but in future
other cases may be added (for example we may support merging of views
with subqueries in select list one day). Relying on this false assumption
led to the usage of wrong table list for field lookups and therefor errors.
With this fix we explicitly use pointer to the beginning of main select's
table list.
mysql-test/r/timezone_grant.result:
Added additional test case for bug#15153 "CONVERT_TZ() is not allowed in
all places in VIEWs" that checks that usage of CONVERT_TZ() function in view
does not require additional privileges.

Added test case for bug#15153 "CONVERT_TZ() is not allowed in all places in
VIEWs".
sql/sql_view.cc:
mysql_make_view():
We should not assume that global table list for view which is handled using
merge algorithm begins from tables belonging to the main select of this
view. Nowadays the above assumption is not true only when one uses
convert_tz() function in view's select list, but in future other cases
may be added (for example we may support merging of views with subqueries
in select list one day). So let us instead explicitly use pointer to the

A fix and a test case for Bug#15683 "crash, Function on nested

This flag is set when we're opening the view in order to build the prelocking list for a query. In this case we should only calculate the list to prelock, and should not merge neither this view nor any of the nested views, of there are any. The flag is used to indicate this mode. |

Fix for BUG#16777: Can not create trigger nor view w/o definer
if --skip-grant-tables specified. The problem is that there is a check that prevents creating a definer with empty host name. In --skip-grant-tables mode this check prevents the user from creating a trigger/view without explicitly specifying its definer. This happens, because in --skip-grant-tables mode CURRENT_USER is ''@''. According to Sanja this check was implemented intentionally. However, according to the MySQL manual it is possible to specify empty host name (as well as empty user name). Moreover, the behaviour for stored routines is different in this aspect -- we allow them to be created with implicit definer. Based on this, we believe it is OK to change the behaviour for views to be similar with the behaviour for stored routines. mysql-test/r/skip_grants.result: Added a test case for BUG#16777. mysql-test/t/skip_grants.test: Added a test case for BUG#16777. sql/mysql_priv.h: Do not check that strlen(host) > 0 in get_default_definer(). sql/sql_parse.cc: Do not check that strlen(host) > 0 in get_default_definer(). sql/sql_view.cc: Do not check that strlen(host) > 0 in get_default_definer(). |

Fix for BUG#16266: Definer is not fully qualified error during replication.
The idea of the fix is to extend support of non-SUID triggers for backward compatibility. Formerly non-SUID triggers were appeared when "new" server is being started against "old" database. Now, they are also created when "new" slave receives updates from "old" master. mysql-test/r/rpl_trigger.result: Updated the result file with the results of the test for BUG#16266. mysql-test/t/rpl_trigger.test: Added the test case for BUG#16266. sql/mysql_priv.h: Added an utility operation to be used from sql_yacc.yy. sql/sql_parse.cc: Add a utility operation to be used from sql_yacc.yy. sql/sql_trigger.cc: Extend support of non-SUID triggers. sql/sql_view.cc: Initialize LEX::definer if DEFINER-clause is missing. sql/sql_yacc.yy: Extended support of non-SUID triggers. mysql-test/std_data/bug16266.000001: A new binlog file for testing a patch for BUG#16266. |

WL#1324 table name to file name encoding
- Encoding itself, implemented as a charset "filename". Originally planned to use '.' as an escape character, but now changed to '@' for two reasons: "ls" does not return file names starting with '.' considering them as a kind of hidden files; some platforms do not allow several dots in a file name. - replacing many calls of my_snprintf() and strnxmov() to the new build_table_filename(). - Adding MY_APPEND_EXT mysys flag, to append an extention rather that replace it. - Replacing all numeric constants in fn_format flag arguments to their mysys definitions, e.g. MY_UNPACK_FILENAME, - Predictability in several function/methods: when a table name can appear with or withot .frm extension. Some functions/methods were changed so accept names strictly with .frm, other - strictly without .frm extensions. Several DBUG_ASSERTs were added to check whether an extension is passed.

Table definition cache, part 2
The table opening process now works the following way:
- Create common TABLE_SHARE object
- Read the .frm file and unpack it into the TABLE_SHARE object
- Create a TABLE object based on the information in the TABLE_SHARE
object and open a handler to the table object
Other noteworthy changes:
- In TABLE_SHARE the most common strings are now LEX_STRING's
- Better error message when table is not found
- Variable table_cache is now renamed 'table_open_cache'
- New variable 'table_definition_cache' that is the number of table defintions that will be cached
- strxnmov() calls are now fixed to avoid overflows
- strxnmov() will now always add one end \0 to result
- engine objects are now created with a TABLE_SHARE object instead of a TABLE object.
- After creating a field object one must call field->init(table) before using it
- For a busy system this change will give you:
- Less memory usage for table object
- Faster opening of tables (if it's has been in use or is in table definition cache)
- Allow you to cache many table definitions objects
- Faster drop of table

- Create a TABLE object based on the information in the TABLE_SHARE
object and open a handler to the table object
open_table_def() is written in such a way that it should be trival to add parsing of the .frm files in new formats
sql/table.h:
TABLE objects for the same database table now share a common TABLE_SHARE object
In TABLE_SHARE the most common strings are now LEX_STRING's
sql/unireg.cc:
Changed arguments to rea_create_table() to have same order as other functions
Call field->init(table) for new created fields
sql/unireg.h:
Added OPEN_VIEW

Reviewing new pushed code
- CHAR() now returns binary string as default - CHAR(X*65536+Y*256+Z) is now equal to CHAR(X,Y,Z) independent of the character set for CHAR() - Test for both ETIMEDOUT and ETIME from pthread_cond_timedwait() (Some old systems returns ETIME and it's safer to test for both values than to try to write a wrapper for each old system) - Fixed new introduced bug in NOT BETWEEN X and X - Ensure we call commit_by_xid or rollback_by_xid for all engines, even if one engine has failed - Use octet2hex() for all conversion of string to hex - Simplify and optimize code client/mysqldump.c: Simple optimizations of new code Indentation fixes client/mysqltest.c: Removed not needed variable include/mysql_com.h: Made octec2hex() more usable mysql-test/r/ctype_utf8.result: CHAR() now returns binary string as default mysql-test/r/func_str.result: CHAR() now returns binary string as default mysql-test/r/range.result: Added test to verify new introduced bug in NOT BETWEEN X and X mysql-test/r/user_var-binlog.result: CHAR() now returns binary string as default mysql-test/r/view.result: More tests of view rename mysql-test/t/ctype_utf8.test: CHAR() now returns binary string as default mysql-test/t/func_str.test: CHAR() now returns binary string as default mysql-test/t/range.test: Added test to verify new introduced bug in NOT BETWEEN X and X mysql-test/t/view.test: More tests of view rename mysys/mf_keycache.c: Indentation changes Test for both ETIMEDOUT and ETIME from pthread_cond_timedwait() mysys/my_os2cond.c: Fix to MySQL coding style Optimized functions mysys/thr_lock.c: Test for both ETIMEDOUT and ETIME from pthread_cond_timedwait() mysys/thr_mutex.c: Test for both ETIMEDOUT and ETIME from pthread_cond_timedwait() server-tools/instance-manager/instance.cc: Test for both ETIMEDOUT and ETIME from pthread_cond_timedwait() server-tools/instance-manager/thread_registry.cc: Test for both ETIMEDOUT and ETIME from pthread_cond_timedwait() sql/ha_federated.cc: Use octet2hex() sql/ha_ndbcluster.cc: Removed not used variable sql/handler.cc: Simplify code Use *NONE* instead of 'none' for not existing storage engine Ensure we call commit_by_xid or rollback_by_xid for all engines, even if one engine has failed sql/item.h: Remove not needed test for *ref. (If ref is set, it should never point at 0) sql/item_func.cc: Test for both ETIMEDOUT and ETIME from pthread_cond_timedwait() Simplify code More comments Require that last argument to find_and_check_access() is given (Made code shorter and faster) sql/item_strfunc.cc: Changed CHAR() to return result in binary collation CHAR(X*65536+Y*256+Z) is now equal to CHAR(X,Y,Z) independent of the character set for CHAR() Bar will shortly add the following syntax: CHAR(.... USING character_set) and ensure that CONVERT(CHAR(....) USING utf8) cuts not legal utf8 strings Use ocet2hex() sql/item_strfunc.h: CHAR() now returns a binary string sql/log_event.cc: Use octet2hex() Simplify code sql/parse_file.cc: Indentation fixes Use for() instead of while() sql/password.c: Make octet2hex() more generally usable by returning pointer to end 0 sql/slave.cc: Test for both ETIMEDOUT and ETIME from pthread_cond_timedwait() sql/sql_base.cc: Indentation fixes sql/sql_insert.cc: Test for both ETIMEDOUT and ETIME from pthread_cond_timedwait() sql/sql_manager.cc: Test for both ETIMEDOUT and ETIME from pthread_cond_timedwait() sql/sql_parse.cc: Don't check thd->db when checking for function privileges sql/sql_prepare.cc: Fixed wrong merge sql/sql_select.cc: Fixed new bug for NOT BETWEEN X and X sql/sql_show.cc: Removed not used variable sql/sql_table.cc: Indentation fixed Removed DBUG_PRINT that is obvious from context sql/sql_view.cc: Simplify code sql/unireg.cc: Use octet2hex() |

Fix for bug #13629 "view test crashes for debug build" (also includes better
fix for bug #13451 "view test produces warning about unfreed memory"). sql/sql_view.cc: mysql_rename_view(): Intead of doing full-blown opening of view and then doing extensive cleanup of its and main LEXes afterwards, let us just read and parse its .FRM file. |
