Bug#15130: CREATE .. SELECT was denied to use advantages of the SQL_BIG_RESULT.
When the SQL_BIG_RESULT flag is specified SELECT should store items from the select list in the filesort data and use them when sending to a client. The get_addon_fields function is responsible for creating necessary structures for that. But this function was allowed to do so only for SELECT and INSERT .. SELECT queries. This makes the SQL_BIG_RESULT useless for the CREATE .. SELECT queries. Now the get_addon_fields allows storing select list items in the filesort data for the CREATE .. SELECT queries. mysql-test/t/create.test: Added a test case for the bug#15130: CREATE .. SELECT was denied to use advantages of the SQL_BIG_RESULT. mysql-test/r/create.result: Added a test case for the bug#15130: CREATE ..

Patch for the following bugs:
- BUG#11986: Stored routines and triggers can fail if the code has a non-ascii symbol - BUG#16291: mysqldump corrupts string-constants with non-ascii-chars - BUG#19443: INFORMATION_SCHEMA does not support charsets properly - BUG#21249: Character set of SP-var can be ignored - BUG#25212: Character set of string constant is ignored (stored routines) - BUG#25221: Character set of string constant is ignored (triggers) There were a few general problems that caused these bugs: 1. Character set information of the original (definition) query for views, triggers, stored routines and events was lost. 2. mysqldump output query in client character set, which can be inappropriate to encode definition-query. 3. INFORMATION_SCHEMA used strings with mixed encodings to display object definition; 1. No query-definition-character set. In order to compile query into execution code, some extra data (such as environment variables or the database character set) is used. The problem here was that this context was not preserved. So, on the next load it can differ from the original one, thus the result will be different. The context contains the following data: - client character set; - connection collation (character set and collation); - collation of the owner database; The fix is to store this context and use it each time we parse (compile) and execute the object (stored routine, trigger, ...). 2. Wrong mysqldump-output. The original query can contain several encodings (by means of character set introducers). The problem here was that we tried to convert original query to the mysqldump-client character set. Moreover, we stored queries in different character sets for different objects (views, for one, used UTF8, triggers used original character set). The solution is - to store definition queries in the original character set; - to change SHOW CREATE statement to output definition query in the binary character set (i.e. without any conversion); - introduce SHOW CREATE TRIGGER statement; - to dump special statements to switch the context to the original one before dumping and restore it afterwards. Note, in order to preserve the database collation at the creation time, additional ALTER DATABASE might be used (to temporary switch the database collation back to the original value). In this case, ALTER DATABASE privilege will be required. This is a backward-incompatible change. 3. INFORMATION_SCHEMA showed non-UTF8 strings The fix is to generate UTF8-query during the parsing, store it in the object and show it in the INFORMATION_SCHEMA. Basically, the idea is to create a copy of the original query convert it to UTF8. Character set introducers are removed and all text literals are converted to UTF8. This UTF8 query is intended to provide user-readable output. It must not be used to recreate the object. Specialized SHOW CREATE statements should be used for this. The reason for this limitation is the following: the original query can contain symbols from several character sets (by means of character set introducers). Example: - original query: CREATE VIEW v1 AS SELECT _cp1251 'Hello' AS c1; - UTF8 query (for INFORMATION_SCHEMA): CREATE VIEW v1 AS SELECT 'Hello' AS c1; client/mysqldump.c: Set original character set and collation before dumping definition query. include/my_sys.h: Move out-parameter to the end of list. mysql-test/lib/mtr_report.pl: Ignore server-warnings during the test case. mysql-test/r/create.result: Update result file. mysql-test/r/ctype_cp932_binlog_stm.result: Update result file. mysql-test/r/events.result: Update result file. mysql-test/r/events_bugs.result: Update result file. mysql-test/r/events_grant.result: Update result file. mysql-test/r/func_in.result: Update result file. mysql-test/r/gis.result: Update result file. mysql-test/r/grant.result: Update result file. mysql-test/r/information_schema.result: Update result file. mysql-test/r/information_schema_db.result: Update result file. mysql-test/r/lowercase_view.result: Update result file. mysql-test/r/mysqldump.result: Update result file. mysql-test/r/ndb_sp.result: Update result file. mysql-test/r/ps.result: Update result file. mysql-test/r/rpl_replicate_do.result: Update result file. mysql-test/r/rpl_sp.result: Update result file. mysql-test/r/rpl_trigger.result: Update result file. mysql-test/r/rpl_view.result: Update result file. mysql-test/r/show_check.result: Update result file. mysql-test/r/skip_grants.result: Update result file. mysql-test/r/sp-destruct.result: Update result file. mysql-test/r/sp-error.result: Update result file. mysql-test/r/sp-security.result: Update result file. mysql-test/r/sp.result: Update result file. mysql-test/r/sql_mode.result: Update result file. mysql-test/r/system_mysql_db.result: Update result file. mysql-test/r/temp_table.result: Update result file. mysql-test/r/trigger-compat.result: Update result file. mysql-test/r/trigger-grant.result: Update result file. mysql-test/r/trigger.result: Update result file. mysql-test/r/view.result: Update result file. mysql-test/r/view_grant.result: Update result file. mysql-test/t/events.test: Update test case (new columns added). mysql-test/t/information_schema.test: Update test case (new columns added). mysql-test/t/show_check.test: Test case for SHOW CREATE TRIGGER in prepared statements and stored routines. mysql-test/t/sp-destruct.test: Update test case (new columns added). mysql-test/t/sp.test: Update test case (new columns added). mysql-test/t/view.test: Update test. mysys/charset.c: Move out-parameter to the end of list. scripts/mysql_system_tables.sql: Add new columns to mysql.proc and mysql.event. scripts/mysql_system_tables_fix.sql: Add new columns to mysql.proc and mysql.event. sql/event_data_objects.cc: Support new attributes for events. sql/event_data_objects.h: Support new attributes for events. sql/event_db_repository.cc: Support new attributes for events. sql/event_db_repository.h: Support new attributes for events. sql/events.cc: Add new columns to SHOW CREATE event resultset. sql/mysql_priv.h: 1.

Bug #26642: create index corrupts table definition in .frm
Thanks to Martin Friebe for finding and submitting a fix for this bug! A table with maximum number of key segments and maximum length key name would have a corrupted .frm file, due to an incorrect calculation of the complete key length. Now the key length is computed correctly (I hope) :-) MyISAM would reject a table with the maximum number of keys and the maximum number of key segments in all keys. It would allow one less than this total maximum. Now MyISAM accepts a table defined with the maximum. (This is a very minor issue.) myisam/mi_open.c: Bug #26642: change >= to > in a comparison (i.e., error only if key_parts_in_table really is greater than MAX_KEY * MAX_KEY_SEG) mysql-test/r/create.result: Bug #26642: test case mysql-test/t/create.test: Bug #26642: test case sql/table.cc: Bug #26642: In create_frm(), fix formula for key_length; it was too small by (keys * 2) bytes |

Bug #28842 Different 'duplicate key' error code between 5.0 and 5.1
The patch for WL 1563 added a new duplicate key error message so that the key name could be provided instead of the key number. But the error code for the new message was used even though that did not need to change. This could cause unnecessary problems for applications that used the old ER_DUP_ENTRY error code to detect duplicate key errors. mysql-test/t/auto_increment.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/create.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/create_select_tmp.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/ctype_ucs2_def.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/ctype_utf8.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/delayed.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/heap.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/heap_btree.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/heap_hash.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/innodb.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/insert_select.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/insert_update.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/join_outer.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/key.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/merge.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/myisam.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/ndb_basic.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/ndb_charset.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/ndb_index_unique.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/ndb_insert.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/ndb_replace.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/ndb_update.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/replace.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/rpl_err_ignoredtable.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/rpl_ndb_do_table.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/rpl_row_create_table.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/rpl_sp.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/show_check.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/sp-error.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/sp.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/sp_trans.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/sp_trans_log.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/temp_table.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/type_binary.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/type_bit.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/type_bit_innodb.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/type_blob.test: Update ER_DUP_ENTRY-related error message values mysql-test/t/type_varchar.test: Update ER_DUP_ENTRY-related error message values mysql-test/r/create.result: Update ER_DUP_ENTRY-related error message values mysql-test/r/rpl_sp.result: Update ER_DUP_ENTRY-related error message values mysql-test/r/sp.result: Update ER_DUP_ENTRY-related error message values mysql-test/include/mix1.inc: Update ER_DUP_ENTRY-related error message values mysql-test/include/mix2.inc: Update ER_DUP_ENTRY-related error message values mysql-test/include/ps_modify.inc: Update ER_DUP_ENTRY-related error message values mysql-test/include/query_cache.inc: Update ER_DUP_ENTRY-related error message values mysql-test/include/varchar.inc: Update ER_DUP_ENTRY-related error message values mysql-test/extra/binlog_tests/insert_select-binlog.test: Update ER_DUP_ENTRY-related error message values mysql-test/extra/binlog_tests/mix_innodb_myisam_binlog.test: Update ER_DUP_ENTRY-related error message values mysql-test/extra/rpl_tests/rpl_auto_increment.test: Update ER_DUP_ENTRY-related error message values mysql-test/extra/rpl_tests/rpl_foreign_key.test: Update ER_DUP_ENTRY-related error message values mysql-test/extra/rpl_tests/rpl_insert_delayed.test: Update ER_DUP_ENTRY-related error message values mysql-test/extra/rpl_tests/rpl_insert_id.test: Update ER_DUP_ENTRY-related error message values mysql-test/extra/rpl_tests/rpl_insert_id_pk.test: Update ER_DUP_ENTRY-related error message values mysql-test/extra/rpl_tests/rpl_loaddata.test: Update ER_DUP_ENTRY-related error message values mysql-test/extra/rpl_tests/rpl_row_basic.test: Update ER_DUP_ENTRY-related error message values mysql-test/extra/rpl_tests/rpl_stm_EE_err2.test: Update ER_DUP_ENTRY-related error message values mysql-test/extra/rpl_tests/rpl_trig004.test: Update ER_DUP_ENTRY-related error message values sql/handler.cc: Restore use of ER_DUP_ENTRY error code even when ER_DUP_ENTRY_WITH_KEY_NAME error message is being used.

5.1 version of fix for:
Bug #23667 "CREATE TABLE LIKE is not isolated from alteration by other connections" Bug #18950 "CREATE TABLE LIKE does not obtain LOCK_open" As well as: Bug #25578 "CREATE TABLE LIKE does not require any privileges on source table". The first and the second bugs resulted in various errors and wrong binary log order when one tried to execute concurrently CREATE TABLE LIKE statement and DDL statements on source table or DML/DDL statements on its target table. The problem was caused by incomplete protection/table-locking against concurrent statements implemented in mysql_create_like_table() routine. We solve it by simply implementing such protection in proper way. Most of actual work for 5.1 was already done by fix for bug 20662 and preliminary patch changing locking in ALTER TABLE. The third bug allowed user who didn't have any privileges on table create its copy and therefore circumvent privilege check for SHOW CREATE TABLE. This patch solves this problem by adding privilege check, which was missing. Finally it also removes some duplicated code from mysql_create_like_table() and thus fixes bug #26869 "TABLE_LIST::table_name_length inconsistent with TABLE_LIST::table_name". mysql-test/r/create-big.result: Added test coverage for concurrency-related issues with CREATE TABLE LIKE. mysql-test/r/create.result: Adjusted error-code in the test case after refactoring code that implements CREATE TABLE ... LIKE. mysql-test/r/grant2.result: Added test for bug#25578 "CREATE TABLE LIKE does not require any privileges on source table". mysql-test/t/create-big.test: Added test coverage for concurrency-related issues with CREATE TABLE LIKE. mysql-test/t/create.test: Adjusted error-code in the test case after refactoring code that implements CREATE TABLE ... LIKE. mysql-test/t/disabled.def: Recent code changes ensured that CREATE TABLE LIKE statement is properly isolated against other statements, so synchronization.test should no longer fail (see fix for bug 20662 and preliminary patch for bug 23667 changing ALTER TABLE locking). mysql-test/t/grant2.test: Added test for bug#25578 "CREATE TABLE LIKE does not require any privileges on source table". sql/handler.h: Introduced new flag for HA_CREATE_INFO::options in order to be able to distinguish CREATE TABLE ... LIKE from other types of CREATE TABLE. sql/mysql_priv.h: mysql_create_like_table() now takes source table name not as a Table_ident object but as regular table list element. sql/sql_lex.h: Removed LEX::like_name member. Now we use special flag in LEX::create_info::options for distinguishing CREATE TABLE ... LIKE from other types of CREATE TABLE and store name of source table as regular element in statement's table list. sql/sql_parse.cc: CREATE TABLE ... LIKE implementation now uses statement's table list for storing information about the source table. We also use flag in LEX::create_info.options for distinguishing it from other types of CREATE TABLE. Finally CREATE TABLE ... LIKE now requires the same privileges on the source tables as SHOW CREATE TABLE. Moved this privilege check to check_show_create_table_access() function. sql/sql_partition.cc: Now we use special flag in LEX::create_info::options for distinguishing CREATE TABLE ... LIKE from other types of CREATE TABLE and store name of source table as regular element in statement's table list. sql/sql_table.cc: mysql_create_like_table(): - Commented and cleaned-up a bit code which is responsible for achieving isolation from concurrent statements. Most of actual work was done by fix for bug 20662 and preliminary patch changing locking locking in ALTER TABLE, so here we do minor things like relaxing locking on source table (we don't need lock on it, to have it open is enough) and adjusting code to make it more friendly against code implementing I_S. - Get rid of duplicated code related to source database/table name handling. All these operations are already done in st_select_lex::add_table_to_list(), so we achieve the same effect by including source table into the statement's table list. sql/sql_yacc.yy: Now we use special flag in LEX::create_info::options for distinguishing CREATE TABLE ... LIKE from other types of CREATE TABLE and store name of source table as regular element in statement's table list. |

Fix for:
Bug #20662 "Infinite loop in CREATE TABLE IF NOT EXISTS ... SELECT with locked tables" Bug #20903 "Crash when using CREATE TABLE .. SELECT and triggers" Bug #24738 "CREATE TABLE ... SELECT is not isolated properly" Bug #24508 "Inconsistent results of CREATE TABLE ... SELECT when temporary table exists" Deadlock occured when one tried to execute CREATE TABLE IF NOT EXISTS ... SELECT statement under LOCK TABLES which held read lock on target table. Attempt to execute the same statement for already existing target table with triggers caused server crashes. Also concurrent execution of CREATE TABLE ... SELECT statement and other statements involving target table suffered from various races (some of which might've led to deadlocks). Finally, attempt to execute CREATE TABLE ... SELECT in case when a temporary table with same name was already present led to the insertion of data into this temporary table and creation of empty non-temporary table. All above problems stemmed from the old implementation of CREATE TABLE ... SELECT in which we created, opened and locked target table without any special protection in a separate step and not with the rest of tables used by this statement. This underminded deadlock-avoidance approach used in server and created window for races. It also excluded target table from prelocking causing problems with trigger execution. The patch solves these problems by implementing new approach to handling of CREATE TABLE ... SELECT for base tables. We try to open and lock table to be created at the same time as the rest of tables used by this statement. If such table does not exist at this moment we create and place in the table cache special placeholder for it which prevents its creation or any other usage by other threads. We still use old approach for creation of temporary tables. Note that we have separate fix for 5.0 since there we use slightly different less intrusive approach. mysql-test/r/create.result: Extended test coverage for CREATE TABLE ... SELECT. In particular added tests for bug #24508 "Inconsistent results of CREATE TABLE ... SELECT when temporary table exists" and bug #20662 "Infinite loop in CREATE TABLE IF NOT EXISTS ... SELECT with locked tables". mysql-test/r/trigger.result: Added test case for bug #20903 "Crash when using CREATE TABLE .. SELECT and triggers" mysql-test/t/create.test: Extended test coverage for CREATE TABLE ... SELECT. In particular added tests for bug #24508 "Inconsistent results of CREATE TABLE ... SELECT when temporary table exists" and bug #20662 "Infinite loop in CREATE TABLE IF NOT EXISTS ... SELECT with locked tables". mysql-test/t/trigger.test: Added test case for bug #20903 "Crash when using CREATE TABLE .. SELECT and triggers" sql/lock.cc: Now for creation of name-lock placeholder lock_table_name() uses auxiliary function table_cache_insert_placeholder(). sql/mysql_priv.h: Removed declaration of non-existing build_table_path() routine. The former mysql_create_table_internal() was renamed to mysql_create_table_no_lock() and now exposed to other modules to give them opportunity of creation of tables in cases when name-lock is already obtained. reopen_name_locked_table() now has 3rd argument which controls linking in of table being opened into THD::open_tables (this is useful in cases when placeholder used for name-locking is already linked into this list). Added declaration of auxiliary function table_cache_insert_placeholder() which is used for creation of table placeholders for name-locking. Added declaration of lock_table_name_if_not_cached() which can be used to take an exclusive name-lock on table if there are no records for it in table cache. Changed signature of unlink_open_table() function to simplify its use and make it useful for table placeholders and tables that are only open. Added auxiliary drop_open_table() routine. Moved declaration of refresh_version to table.h header to make it accessible from inline methods of TABLE class. MYSQL_OPEN_IGNORE_LOCKED_TABLES flag is no longer used. Instead MYSQL_OPEN_TEMPORARY_ONLY option was added. sql/sql_base.cc: Added support for the new approach to the handling of CREATE TABLE ... SELECT for base tables. Now we try to open and lock table to be created at the same time as the rest of tables used by this statement. If such table does not exist at this moment we create and place in the table cache special placeholder for it which prevents its creation or any other usage by other threads. Note significant distinctions of this placeholder from the placeholder used for normal name-lock: 1) It is treated like open table by other name-locks so it does not allow name-lock taking operations like DROP TABLE or RENAME TABLE to proceed. 2) it is linked into THD::open_tables list and automatically removed during close_thread_tables() call open_tables(): Implemented logic described above. To do this added auxiliary check_if_table_exists() function. Removed support for MYSQL_OPEN_IGNORE_LOCKED_TABLES option which is no longer used. Added MYSQL_OPEN_TEMPORARY_ONLY which is used to restrict search for temporary tables only. close_cached_tables()/close_thread_table()/reopen_tables()/ close_old_data_files()/table_is_used()/remove_table_from_cache(): Added support for open placeholders (note that we also use them when we need to re-open tables during flush). unlink_open_table(): Changed function signature to simplify its use and to make useful for open placeholders and tables which are only open and not locked. Added auxiliary drop_open_table() routine. reopen_name_locked_table(): Now has 3rd argument which controls linking in of table being opened into THD::open_tables (this is useful in cases when placeholder used for name-locking is already linked into this list). Added auxiliary table_cache_insert_placeholder() routine which simplifies creation of placeholders used for name-locking. Added lock_table_name_if_not_cached() which can be used to take an exclusive name-lock on table if there are no records for it in table cache. sql/sql_handler.cc: Adjusted mysql_ha_mark_tables_for_reopen() routine to properly handle placeholders which now can be linked into open tables list. sql/sql_insert.cc: Introduced new approach to handling of base tables in CREATE TABLE ... SELECT statement. Now we try to open and lock table to be created at the same time as the rest of tables used by this statement. If such table does not exist at this moment we create and place in the table cache special placeholder for it which prevents its creation or any other usage by other threads. By doing this we avoid races which existed with previous approach in which we created, opened and locked target in separate step without any special protection. This also allows properly calculate prelocking set in cases when target table already exists and has some on insert triggers. Note that we don't employ the same approach for temporary tables (this is okay as such tables are unaffected by other threads). Changed create_table_from_items() and methods of select_create class to implement this approach. sql/sql_parse.cc: The new approach to handling of CREATE TABLE ... SELECT for base tables assumes that all tables (including table to be created) are opened and (or) locked at the same time. So in cases when we create base table we have to pass to open_and_lock_tables() table list which includes target table. sql/sql_prepare.cc: The new approach to handling of CREATE TABLE ... SELECT for base tables assumes that all tables (including table to be created) are opened and (or) locked at the same time. So in cases when we create base table we have to pass to open_and_lock_tables() table list which includes target table. sql/sql_table.cc: Changed mysql_create_table(), mysql_create_like_table() and mysql_alter_table() (in rename case) to obtain exclusive name-lock on the non-temporary table which is going to be created (to which we going to rename). This ensures that not only destination table doesn't exist on disk but also that there are no placeholder in table cache for it (i.e. there is no CREATE TABLE ... SELECT operation in progress for it). Note that to avoid deadlocks while taking these name-locks this code assumes that existence of any record for table in table cache (even name-lock) means that table exists. Altough such check can lead to false positives these should occur only in case of highly concurrent DDL operations on the table and should not break binary logging. Renamed mysql_create_table_internal() to mysql_create_table_no_lock() and made it accessible from other files to give them ability to create table in situation when name-lock is already obtained or not relevant. Adjusted calls to reopen_name_locked_table(), which now takes extra argument, which controls linking of open table into THD::open_tables list. Removed redundant setting of table's 'version' field before calls to close_cached_table(). This function will set it to 0 itself anyway. sql/sql_trigger.cc: reopen_name_locked_tables() now has one more argument which controls linking of opened table into the THD::open_tables list. sql/sql_yacc.yy: The new approach to handling of CREATE TABLE ... SELECT statement for base tables assumes that all tables including table to be created are open and (or) locked at the same time. Therefore we need to set correct lock for target table. sql/table.h: Moved declaration of refresh_version variable from mysql_priv.h to make it accessible from inline methods of TABLE class. Renamed TABLE::locked_by_flush member to open_placeholder since now it is also used for taking exclusive name-lock and not only by flush. Introduced TABLE::is_name_opened() helper method which can be used to distinguish TABLE instances corresponding to open tables or placeholders for them from closed instances (e.g. due to their old version). Also introduced TABLE::needs_reopen_or_name_lock() helper which allows to check if TABLE instance corresponds to outdated version of table or to name-lock placeholder. Introduced TABLE_LIST::create member which marks elements of table list corresponds to the table to be created. Adjusted TABLE_LIST::placeholder() method to take into account name-lock placeholders for tables to be created (this, for example, allows to properly handle such placeholders in lock_tables()). Finally, moved currently unused TABLE::open_next/open_prev members under ifdef NOT_YET. mysql-test/r/create_select-big.result: New BitKeeper file ``mysql-test/r/create_select-big.result'' mysql-test/t/create_select-big.test: New BitKeeper file ``mysql-test/t/create_select-big.test'' |

Fix for:
Bug #20662 "Infinite loop in CREATE TABLE IF NOT EXISTS ... SELECT with locked tables" Bug #20903 "Crash when using CREATE TABLE .. SELECT and triggers" Bug #24738 "CREATE TABLE ... SELECT is not isolated properly" Bug #24508 "Inconsistent results of CREATE TABLE ... SELECT when temporary table exists" Deadlock occured when one tried to execute CREATE TABLE IF NOT EXISTS ... SELECT statement under LOCK TABLES which held read lock on target table. Attempt to execute the same statement for already existing target table with triggers caused server crashes. Also concurrent execution of CREATE TABLE ... SELECT statement and other statements involving target table suffered from various races (some of which might've led to deadlocks). Finally, attempt to execute CREATE TABLE ... SELECT in case when a temporary table with same name was already present led to the insertion of data into this temporary table and creation of empty non-temporary table. All above problems stemmed from the old implementation of CREATE TABLE ... SELECT in which we created, opened and locked target table without any special protection in a separate step and not with the rest of tables used by this statement. This underminded deadlock-avoidance approach used in server and created window for races. It also excluded target table from prelocking causing problems with trigger execution. The patch solves these problems by implementing new approach to handling of CREATE TABLE ... SELECT for base tables. We try to open and lock table to be created at the same time as the rest of tables used by this statement. If such table does not exist at this moment we create and place in the table cache special placeholder for it which prevents its creation or any other usage by other threads. We still use old approach for creation of temporary tables. Also note that we decided to postpone introduction of some tests for concurrent behaviour of CREATE TABLE ... SELECT till 5.1. The main reason for this is absence in 5.0 ability to set @@debug variable at runtime, which can be circumvented only by using several test files with individual .opt files. Since the latter is likely to slowdown test-suite unnecessary we chose not to push this tests into 5.0, but run them manually for this version and later push their optimized version into 5.1 mysql-test/r/create.result: Extended test coverage for CREATE TABLE ... SELECT. In particular added tests for bug #24508 "Inconsistent results of CREATE TABLE ... SELECT when temporary table exists" and bug #20662 "Infinite loop in CREATE TABLE IF NOT EXISTS ... SELECT with locked tables". mysql-test/r/trigger.result: Added test case for bug #20903 "Crash when using CREATE TABLE .. SELECT and triggers" mysql-test/t/create.test: Extended test coverage for CREATE TABLE ... SELECT. In particular added tests for bug #24508 "Inconsistent results of CREATE TABLE ... SELECT when temporary table exists" and bug #20662 "Infinite loop in CREATE TABLE IF NOT EXISTS ... SELECT with locked tables". mysql-test/t/trigger.test: Added test case for bug #20903 "Crash when using CREATE TABLE .. SELECT and triggers" sql/lock.cc: Now for creation of name-lock placeholder in lock_table_name() we use auxiliary function table_cache_insert_placeholder(). sql/mysql_priv.h: Made build_table_path() function available outside of sql_table.cc file. reopen_name_locked_table() now has 3rd argument which controls linking in of table being opened into THD::open_tables (this is useful in cases when placeholder used for name-locking is already linked into this list). Added declaration of auxiliary function table_cache_insert_placeholder() which is used for creation of table placeholders for name-locking. Added declaration of table_cache_has_open_placeholder() function which can be used for checking if table cache contains an open placeholder for the table and if this placeholder was created by another thread. (This function is needed only in 5.0 where we use it in various versions of CREATE TABLE in order to protect it from concurrent CREATE TABLE ... SELECT operations for the table. Starting from 5.1 we use different approach so it is going to be removed there). Made close_old_data_files() static within sql_base.cc file. Added auxiliary drop_open_table() routine. Moved declaration of refresh_version to table.h header to make it accessible from inline methods of TABLE class. MYSQL_OPEN_IGNORE_LOCKED_TABLES flag is no longer used. Instead MYSQL_OPEN_TEMPORARY_ONLY option was added. sql/sql_base.cc: Added support for the new approach to the handling of CREATE TABLE ... SELECT for base tables. Now we try to open and lock table to be created at the same time as the rest of tables used by this statement. If such table does not exist at this moment we create and place in the table cache special placeholder for it which prevents its creation or any other usage by other threads.

Added MYSQL_OPEN_TEMPORARY_ONLY which is used to restrict search for temporary tables only. close_cached_tables()/close_thread_table()/reopen_tables()/ close_old_data_files()/table_is_used()/remove_table_from_cache(): Added support for open placeholders (note that we also use them when we need to re-open tables during flush). Added auxiliary drop_open_table() routine. reopen_name_locked_table(): Now has 3rd argument which controls linking in of table being opened into THD::open_tables (this is useful in cases when placeholder used for name-locking is already linked into this list). Added auxiliary table_cache_insert_placeholder() routine which simplifies creation of placeholders used for name-locking.

So in cases when we create base table we have to pass to open_and_lock_tables() table list which includes target table. sql/sql_table.cc: Now mysql_create_table_internal(), mysql_create_like_table() and mysql_alter_table() not only check that destination table doesn't exist on disk but also check that there is no create placeholder in table cache for it (i.e. there is no CREATE TABLE ... SELECT operation in progress for it). Note that starting from 5.1 we use different approach in order to to protect CREATE TABLE ... SELECT from concurrent CREATE TABLE (ALTER TABLE ... RENAME) operations, the latter simply take name-locks on table before its creation (on target table name before renaming). Also made build_table_path() available from other files and asjusted calls to reopen_name_locked_table(), which now takes extra argument, which controls linking of open table into THD::open_tables list. sql/sql_trigger.cc: reopen_name_locked_tables() now has one more argument which controls linking of opened table into the THD::open_tables list. sql/sql_yacc.yy: The new approach to handling of CREATE TABLE ...

Bug #26642: create index corrupts table definition in .frm
Thanks to Martin Friebe for finding and submitting a fix for this bug! A table with maximum number of key segments and maximum length key name would have a corrupted .frm file, due to an incorrect calculation of the complete key length. Now the key length is computed correctly (I hope) :-) MyISAM would reject a table with the maximum number of keys and the maximum number of key segments in all keys. It would allow one less than this total maximum. Now MyISAM accepts a table defined with the maximum. (This is a very minor issue.) myisam/mi_open.c: change >= to > in a comparison (i.e., error only if key_parts_in_table really is greater than MAX_KEY * MAX_KEY_SEG) mysql-test/r/create.result: Add test results for bug #26642 (create index corrupts table definition in .frm) mysql-test/t/create.test: Add test case for bug #26642 (create index corrupts table definition in .frm) sql/table.cc: In create_frm(), fix formula for key_length; it was too small by (keys * 2) bytes |

Bug #24791: Union with AVG-groups generates wrong results
The problem in this bug is when we create temporary tables. When temporary tables are created for unions, there is some inferrence being carried out regarding the type of the column. Whenever this column type is inferred to be REAL (i.e. FLOAT or DOUBLE), MySQL will always try to maintain exact precision, and if that is not possible (there are hardware limits, since FLOAT and DOUBLE are stored as approximate values) will switch to using approximate values. The problem here is that at this point the information about number of significant digits is not available. Furthermore, the number of significant digits should be increased for the AVG function, however, this was not properly handled. There are 4 parts to the problem: #1: DOUBLE and FLOAT fields don't display their proper display lengths in max_display_length(). This is hard-coded as 53 for DOUBLE and 24 for FLOAT. Now changed to instead return the field_length. #2: Type holders for temporary tables do not preserve the max_length of the Item's from which they are created, and is instead reverted to the 53 and 24 from above. This causes *all* fields to get non-fixed significant digits. #3: AVG function does not update max_length (display length) when updating number of decimals. #4: The function that switches to non-fixed number of significant digits should use DBL_DIG + 2 or FLT_DIG + 2 as cut-off values (Since fixed precision does not use the 'e' notation) Of these points, #1 is the controversial one, but this change is preferred and has been cleared with Monty. The function causes quite a few unit tests to blow up and they had to b changed, but each one is annotated and motivated. We frequently see the magical 53 and 24 give way to more relevant numbers. mysql-test/r/create.result: bug#24791 changed test result With the changes made for FLOAT and DOUBLE, the original display lengths are now preserved. mysql-test/r/temp_table.result: bug#24791 changed test resullt Test case added mysql-test/r/type_float.result: bug#24791 changed test result delta 1: field was originally declared as DOUBLE with no display length, so the hardware maximum is chosen rather than 53. delta 2: fields exceed the maximum precision and thus switch to non-fixed significant digits delta 3: Same as above, number of decmals and significant digits was not specified when t3 was created. mysql-test/t/temp_table.test: bug#24791 Test case sql/field.h: bug#24791 The method max_display_length is reimplemented as uint32 max_display_length() { return field_length; } in Field_double and Field_float. Since all subclasses of Field_real now have the same implementation of this method, the implementation has been moved up the hierarchy to Field_real. sql/item.cc: bug#24791 We switch to a non-fixed number of significant digits (by setting decimals=NOT_FIXED_DECIMAL) if the calculated display length is greater than the display length of a value with the maximum precision. These values differ for double and float, obviously. sql/item_sum.cc: bug#24791 We must increase the display length accordinly whenever we change number of decimal places. |

Fixed bug#12185: Data type aggregation may produce wrong result
The Item::tmp_table_field_from_field_type() function creates Field_datetime object instead of Field_timestamp object for timestamp field thus always changing data type is a tmp table is used. The Field_blob object constructor which is used in the Item::tmp_table_field_from_field_type() is always setting packlength field of newly created blob to 4. This leads to changing fields data type for example from the blob to the longblob if a temporary table is used. The Item::make_string_field() function always converts Field_string objects to Field_varstring objects. This leads to changing data type from the char/binary to varchar/varbinary. Added appropriate Field_timestamp object constructor for using in the Item::tmp_table_field_from_field_type() function. Added Field_blob object constructor which sets pack length according to max_length argument. The Item::tmp_table_field_from_field_type() function now creates Field_timestamp object for a timestamp field. The Item_type_holder::display_length() now returns correct NULL length NULL length. The Item::make_string_field() function now doesn't change Field_string to Field_varstring in the case of Item_type_holder. The Item::tmp_table_field_from_field_type() function now uses the Field_blob constructor which sets packlength according to max_length. mysql-test/t/union.test: Added test case for bug#12185: Data type aggregation may produce wrong result Corrected test case after fix for bug#12185 mysql-test/t/innodb.test: Corrected test case after fix for bug#12185 mysql-test/r/union.result: Added test case for bug#12185: Data type aggregation may produce wrong result Corrected test case after fix for bug#12185 mysql-test/r/innodb.result: Corrected test case after fix for bug#12185 mysql-test/r/create.result: Corrected the test case after fixing bug#12185 sql/field.h: Fixed bug#12185: Data type aggregation may produce wrong result Added Field_blob object constructor which sets packlength according to max_length argument. sql/item.cc: Fixed bug#12185: Data type aggregation may produce wrong result The Item::make_string_field() function now doesn't change Field_string to Field_varstring in the case of Item_type_holder.

Fixed bug #19714.
DESCRIBE returned the type BIGINT for a column of a view if the column was specified by an expression over values of the type INT. E.g. for the view defined as follows: CREATE VIEW v1 SELECT COALESCE(f1,f2) FROM t1 DESCRIBE returned type BIGINT for the only column of the view if f1,f2 are columns of the INT type. At the same time DESCRIBE returned type INT for the only column of the table defined by the statement: CREATE TABLE t2 SELECT COALESCE(f1,f2) FROM t1. This inconsistency was removed by the patch. Now the code chooses between INT/BIGINT depending on the precision of the aggregated column type. Thus both DESCRIBE commands above returns type INT for v1 and t2. mysql-test/r/analyse.result: Adjusted the results after having fixed bug #19714. mysql-test/r/bigint.result: Adjusted the results after having fixed bug #19714. mysql-test/r/create.result: Adjusted the results after having fixed bug #19714. mysql-test/r/olap.result: Adjusted the results after having fixed bug #19714. mysql-test/r/ps_2myisam.result: Adjusted the results after having fixed bug #19714. mysql-test/r/ps_3innodb.result: Adjusted the results after having fixed bug #19714. mysql-test/r/ps_4heap.result: Adjusted the results after having fixed bug #19714. mysql-test/r/ps_5merge.result: Adjusted the results after having fixed bug #19714. mysql-test/r/ps_6bdb.result: Adjusted the results after having fixed bug #19714. mysql-test/r/ps_7ndb.result: Adjusted the results after having fixed bug #19714. mysql-test/r/sp.result: Adjusted the results after having fixed bug #19714. mysql-test/r/subselect.result: Adjusted the results after having fixed bug #19714. mysql-test/r/type_ranges.result: Adjusted the results after having fixed bug #19714. mysql-test/r/view.result: Added a test case for bug #19714. mysql-test/t/view.test: Added a test case for bug #19714. |

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. |
