unknown	289cc26c64	Bug#21074 Large query_cache freezes mysql server sporadically under heavy load Invaldating a subset of a sufficiently large query cache can take a long time. During this time the server is efficiently frozen and no other operation can be executed. This patch addresses this problem by moving the locks which cause the freezing and also by temporarily disable the query cache while the invalidation takes place. sql/ha_ndbcluster.cc: - mysql_rm_table_part2 has a new parameter to indicate if OPEN_lock mutex protection is needed. sql/lock.cc: - Added function for acquiring table name exclusive locks. - Added function for asserting that table name lock is acquired. sql/mysql_priv.h: - Added function for acquiring table name exclusive locks. - Added function for asserting that table name lock is acquired. - Added parameter to mysql_rm_table_part2 to indicate whether OPEN_lock mutex protection is needed or not. sql/sql_cache.cc: - Changed flush_in_progress-flag into a state and added a function, is_flushing() to reflect on this state. A new state was needed to indicate that a partial invalidation was in progress. - An unused parameter 'under_guard' was removed. - The Query_cache mutex structural_guard was pushed down into one invalidate_table function to avoid multiple entry points which makes maintainens more difficult. - Instead of keeping the structural_guard mutex during the entire invalidation we set the query cache status state to TABLE_FLUSH_IN_PROGRESS to temporarily disable the cache and avoid locking other threads needing the Query_cache resource. sql/sql_cache.h: - Changed flush_in_progress-flag into a state and added a function, is_flushing() to reflect on this state. A new state was needed to indicate that a partial invalidation was in progress. - An unused parameter 'under_guard' was removed. - The Query_cache mutex structural_guard was pushed down into one invalidate_table function to avoid multiple entry points which makes maintainens more difficult. - Instead of keeping the structural_guard mutex during the entire invalidation we set the query cache status state to TABLE_FLUSH_IN_PROGRESS to temporarily disable the cache and avoid locking other threads needing the the Query_cache resource. sql/sql_db.cc: - mysql_rm_table_part2_with_lock is redundant and replaced with mysql_rm_table_part2. sql/sql_parse.cc: - Function query_cache_invalidate3 isn't protect by a lock and we have a race condition. - Moving this function into mysql_rename_tables and make sure it is protected by a exclusive table name lock. sql/sql_rename.cc: - Function query_cache_invalidation3 isn't protect by a lock and we have a race condition. - Moving this function into mysql_rename_tables and make sure it is protected by a exclusive table name lock. - Instead of using LOCK_open mutex, which excludes all other threads, the lock is changed into exclusive table name locks instead. This prevents us from locking the server if a query cache invalidation would take a long time to complete. sql/sql_table.cc: - Instead of using LOCK_open mutex, which excludes all other threads, the lock is changed into exclusive table name locks instead. This prevents us from locking the server if a query cache invalidation would take a long time to complete. - Added new parameter to mysql_rm_table_part2 to control whether OPEN_lock mutex needs to be aquired or not. This is currently needed by the NDB implemenation. sql/sql_trigger.cc: - Table_triggers don't need to be protexted by LOCK_open mutex. This patch cancel this restriction. - Refactored comments to doxygen style.	19 years ago
unknown	358b942b20	Unify profiling SHOW code and INFORMATION_SCHEMA code for profiling. Also, Bug#26938: profiling client hang if used before enabled In the SHOW command, not sending header data because we had no rows to send was a protocol violation. Porting the SHOW PROFILE command to use the Information Schema table avoids that problem. mysql-test/r/profiling.result: Add headers of pre-profile SHOW test. mysql-test/t/profiling.test: Verify that the protocol isn't violated if we ask for profiling info before profiling has recorded anything. sql/sql_parse.cc: Remove SQLCOM_SHOW_PROFILE and add a I_S schema table entry. sql/sql_profile.cc: Add SHOW column-names and a new function that takes profile options set in the parser and packs a list of selected fields from the I_S table implementation. sql/sql_profile.h: Remove unused functions and add a new function. sql/sql_show.cc: Add a pointer to the function that selects fields from I_S table for SHOW command. sql/sql_yacc.yy: Prepare an I_S table for SHOW PROFILE. sql/table.h: Rename to match the intention.	19 years ago
unknown	405f82d390	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.

unknown	39459397cd	Bug #29154 : LOCK TABLES is not atomic when >1 InnoDB tables are locked LOCK TABLES takes a list of tables to lock. It may lock several tables successfully and then encounter a tables that it can't lock, e.g. because it's locked. In such case it needs to undo the locks on the already locked tables. And it does that. But it has also notified the relevant table storage engine handlers that they should lock. The only reliable way to ensure that the table handlers will give up their locks is to end the transaction. This is what UNLOCK TABLE does : it ends the transaction if there were locked tables by LOCK tables. It is possible to end the transaction when the lock fails in LOCK TABLES because LOCK TABLES ends the transaction at its start already. Fixed by ending (again) the transaction when LOCK TABLES fails to lock a table. mysql-test/r/innodb_mysql.result: Bug #29154: test case mysql-test/t/innodb_mysql.test: Bug #29154: test case sql/sql_parse.cc: Bug #29154: end the trasaction at a failing LOCK TABLES so the handler can free its locks.	19 years ago
unknown	099be80130	Bug#28846 Use of undocumented Prepared Statements crashes server ALTER VIEW is currently not supported as a prepared statement and should be disabled as such as they otherwise could cause server crashes. ALTER VIEW is currently not supported when called from stored procedures or functions for related reasons and should also be disabled.

unknown	fe593bf1ab	Bug #26418 : Slave out of sync after CREATE/DROP TEMPORARY TABLE + ROLLBACK on master The transaction ability of the storage engines of the tables on the replication master and the replication slave must generally be the same. When the storage engine type of the slave is non-transactional then transactions on the master that mix update of transactional and non-transactional tables should be avoided because they will cause inconsistency of the data between the master's transactional table and the slave's non-transactional table. The effect described by this bug is actually expected. A detailed test case is added (to be merged later to the updated rpl_ddl.test), as there was no coverage by the existing tests.

unknown	b11f1d0c97	5.1 version of a fix and test cases for bugs: Bug#4968 ""Stored procedure crash if cursor opened on altered table" Bug#6895 "Prepared Statements: ALTER TABLE DROP COLUMN does nothing" Bug#19182 "CREATE TABLE bar (m INT) SELECT n FROM foo; doesn't work from stored procedure." Bug#19733 "Repeated alter, or repeated create/drop, fails" Bug#22060 "ALTER TABLE x AUTO_INCREMENT=y in SP crashes server" Bug#24879 "Prepared Statements: CREATE TABLE (UTF8 KEY) produces a growing key length" (this bug is not fixed in 5.0) Re-execution of CREATE DATABASE, CREATE TABLE and ALTER TABLE statements in stored routines or as prepared statements caused incorrect results (and crashes in versions prior to 5.0.25). In 5.1 the problem occured only for CREATE DATABASE, CREATE TABLE SELECT and CREATE TABLE with INDEX/DATA DIRECTOY options). The problem of bugs 4968, 19733, 19282 and 6895 was that functions mysql_prepare_table, mysql_create_table and mysql_alter_table are not re-execution friendly: during their operation they modify contents of LEX (members create_info, alter_info, key_list, create_list), thus making the LEX unusable for the next execution. In particular, these functions removed processed columns and keys from create_list, key_list and drop_list. Search the code in sql_table.cc for drop_it.remove() and similar patterns to find evidence. The fix is to supply to these functions a usable copy of each of the above structures at every re-execution of an SQL statement. To simplify memory management, LEX::key_list and LEX::create_list were added to LEX::alter_info, a fresh copy of which is created for every execution. The problem of crashing bug 22060 stemmed from the fact that the above metnioned functions were not only modifying HA_CREATE_INFO structure in LEX, but also were changing it to point to areas in volatile memory of the execution memory root. The patch solves this problem by creating and using an on-stack copy of HA_CREATE_INFO in mysql_execute_command. Additionally, this patch splits the part of mysql_alter_table that analizes and rewrites information from the parser into a separate function - mysql_prepare_alter_table, in analogy with mysql_prepare_table, which is renamed to mysql_prepare_create_table. mysql-test/r/ps.result: Update test results (Bug#19182, Bug#22060, Bug#4968, Bug#6895) mysql-test/r/sp.result: Update results (Bug#19733) mysql-test/t/ps.test: Add test cases for Bug#19182, Bug#22060, Bug#4968, Bug#6895 mysql-test/t/sp.test: Add a test case for Bug#19733 sql/field.h: Implement a deep copy constructor for create_field sql/mysql_priv.h: LEX::key_list and LEX::create_list were moved to LEX::alter_info.

Replace pair<columns, keys> with an instance of Alter_info in select_create constructor. We create a new copy of Alter_info each time we re-execute SELECT .. CREATE prepared statement. sql/sql_insert.cc: Adjust to a new signature of create_table_from_items. sql/sql_lex.cc: Implement Alter_info::Alter_info that would make a "deep" copy of all definition lists (keys, columns). Move is_partition_management() from sql_partition.cc (feature-based file division is evil). sql/sql_lex.h: Move key_list and create_list to class Alter_info. Implement Alter_info::Alter_info that can be used with PS and SP. Get rid of Alter_info::clear() which was an attempt to save on matches and always use Alter_info::reset(). Implement an auxiliary Alter_info::init_for_create_from_alter() which is used in mysql_alter_table. sql/sql_list.cc: Implement a copy constructor of class List that makes a deep copy of all list nodes. sql/sql_list.h: Implement a way to make a deep copy of all list nodes. sql/sql_parse.cc: Adjust to new signatures of mysql_create_table, mysql_alter_table, select_create. Functions mysql_create_index and mysql_drop_index has become identical after initialization of alter_info was moved to the parser, and were merged. Flag enable_slow_log was not updated for SQLCOM_DROP_INDEX, which was a bug. Just like CREATE INDEX, DROP INDEX is currently done via complete table rebuild and is rightfully a slow administrative statement. sql/sql_partition.cc: Move is_partition_management() to sql_lex.cc Adjust code to the new Alter_info. sql/sql_table.cc: Adjust mysql_alter_table, mysql_recreate_table, mysql_create_table, mysql_prepare_table to new signatures. Rename mysql_prepare_table to mysql_prepare_create_table. Make sure it follows the convention and returns FALSE for success and TRUE for error. Move parts of mysql_alter_table to mysql_prepare_alter_table. Move the first invokation of mysql_prepare_table from mysql_alter_table to compare_tables, as it was needed only for the purpose of correct comparison. Since now Alter_info itself is created in the runtime mem root, adjust mysql_prepare_table to always allocate memory in the runtime memory root. Remove dead code. sql/sql_yacc.yy: LEX::key_list and LEX::create_list moved to class Alter_info	19 years ago

unknown	206a6bb176	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 ...

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 ...

unknown	bb64e39e0a	Bug#21554 (sp_cache.cc: violates C++ aliasing rules) The problem reported is a compile bug, reported by the development GCC team with GCC 4.2. The original issue can no longer be reproduced in MySQL 5.1, since the configure script no longer define HAVE_ATOMIC_ADD, which caused the Linux atomic functions to be used (and cause a problem with an invalid cast). This patch implements some code cleanup for 5.1 only, which was identified during the investigation of this issue. With this patch, statistics maintained in THD::status_var are by definition owned by the running thread, and do not need to be protected against race conditions. These statistics are maintained by the status_var_* helpers, which do not require any lock. include/my_global.h: General cleanup of thread_safe_increment / statistic_increment include/my_pthread.h: General cleanup of thread_safe_increment / statistic_increment sql/filesort.cc: General cleanup of thread_safe_increment / statistic_increment sql/handler.cc: General cleanup of thread_safe_increment / statistic_increment sql/sql_insert.cc: General cleanup of thread_safe_increment / statistic_increment sql/sql_parse.cc: General cleanup of thread_safe_increment / statistic_increment sql/sql_prepare.cc: General cleanup of thread_safe_increment / statistic_increment sql/sql_select.cc: General cleanup of thread_safe_increment / statistic_increment	19 years ago
unknown	d46c8ce634	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''	19 years ago

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.

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.

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 ... 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()).	19 years ago
unknown	f252f9248a	WL#3817: Simplify string / memory area types and make things more consistent (first part) The following type conversions was done: - Changed byte to uchar - Changed gptr to uchar* - Change my_string to char * - Change my_size_t to size_t - Change size_s to size_t Removed declaration of byte, gptr, my_string, my_size_t and size_s. Following function parameter changes was done: - All string functions in mysys/strings was changed to use size_t instead of uint for string lengths. - All read()/write() functions changed to use size_t (including vio). - All protocoll functions changed to use size_t instead of uint - Functions that used a pointer to a string length was changed to use size_t* - Changed malloc(), free() and related functions from using gptr to use void * as this requires fewer casts in the code and is more in line with how the standard functions work. - Added extra length argument to dirname_part() to return the length of the created string. - Changed (at least) following functions to take uchar* as argument: - db_dump() - my_net_write() - net_write_command() - net_store_data() - DBUG_DUMP() - decimal2bin() & bin2decimal() - Changed my_compress() and my_uncompress() to use size_t. Changed one argument to my_uncompress() from a pointer to a value as we only return one value (makes function easier to use). - Changed type of 'pack_data' argument to packfrm() to avoid casts. - Changed in readfrm() and writefrom(), ha_discover and handler::discover() the type for argument 'frmdata' to uchar** to avoid casts. - Changed most Field functions to use uchar* instead of char* (reduced a lot of casts). - Changed field->val_xxx(xxx, new_ptr) to take const pointers. Other changes: - Removed a lot of not needed casts - Added a few new cast required by other changes - Added some cast to my_multi_malloc() arguments for safety (as string lengths needs to be uint, not size_t). - Fixed all calls to hash-get-key functions to use size_t. (Needed to be done explicitely as this conflict was often hided by casting the function to hash_get_key). - Changed some buffers to memory regions to uchar to avoid casts. - Changed some string lengths from uint to size_t. - Changed field->ptr to be uchar* instead of char. This allowed us to get rid of a lot of casts. - Some changes from true -> TRUE, false -> FALSE, unsigned char -> uchar - Include zlib.h in some files as we needed declaration of crc32() - Changed MY_FILE_ERROR to be (size_t) -1. - Changed many variables to hold the result of my_read() / my_write() to be size_t. This was needed to properly detect errors (which are returned as (size_t) -1). - Removed some very old VMS code - Changed packfrm()/unpackfrm() to not be depending on uint size (portability fix) - Removed windows specific code to restore cursor position as this causes slowdown on windows and we should not mix read() and pread() calls anyway as this is not thread safe. Updated function comment to reflect this. Changed function that depended on original behavior of my_pwrite() to itself restore the cursor position (one such case). - Added some missing checking of return value of malloc(). - Changed definition of MOD_PAD_CHAR_TO_FULL_LENGTH to avoid 'long' overflow. - Changed type of table_def::m_size from my_size_t to ulong to reflect that m_size is the number of elements in the array, not a string/memory length. - Moved THD::max_row_length() to table.cc (as it's not depending on THD). Inlined max_row_length_blob() into this function. - More function comments - Fixed some compiler warnings when compiled without partitions. - Removed setting of LEX_STRING() arguments in declaration (portability fix). - Some trivial indentation/variable name changes. - Some trivial code simplifications: - Replaced some calls to alloc_root + memcpy to use strmake_root()/strdup_root(). - Changed some calls from memdup() to strmake() (Safety fix) - Simpler loops in client-simple.c BitKeeper/etc/ignore: added libmysqld/ha_ndbcluster_cond.cc --- added debian/defs.mk debian/control

unknown	3eff7d4dd5	Bug#25411 (trigger code truncated), PART I The issue found with bug 25411 is due to the function skip_rear_comments() which damages the source code while implementing a work around. The root cause of the problem is in the lexical analyser, which does not process special comments properly. For special comments like : [1] aaa /!50000 bbb / ccc since 5.0 is a version older that the current code, the parser is in lining the content of the special comment, so that the query to process is [2] aaa bbb ccc However, the text of the query captured when processing a stored procedure, stored function or trigger (or event in 5.1), can be after rebuilding it: [3] aaa bbb / ccc which is wrong. To fix bug 25411 properly, the lexical analyser needs to return [2] when in lining special comments. In order to implement this, some preliminary cleanup is required in the code, which is implemented by this patch. Before this change, the structure named LEX (or st_lex) contains attributes that belong to lexical analysis, as well as attributes that represents the abstract syntax tree (AST) of a statement. Creating a new LEX structure for each statements (which makes sense for the AST part) also re-initialized the lexical analysis phase each time, which is conceptually wrong. With this patch, the previous st_lex structure has been split in two: - st_lex represents the Abstract Syntax Tree for a statement. The name "lex" has not been changed to avoid a bigger impact in the code base. - class lex_input_stream represents the internal state of the lexical analyser, which by definition should not* be reinitialized when parsing multiple statements from the same input stream. This change is a pre-requisite for bug 25411, since the implementation of lex_input_stream will later improve to deal properly with special comments, and this processing can not be done with the current implementation of sp_head::reset_lex and sp_head::restore_lex, which interfere with the lexer. This change set alone does not fix bug 25411. sql/item_func.cc: Refactoring, separate lex_input_stream from st_lex. sql/log_event.cc: Refactoring, separate lex_input_stream from st_lex. sql/mysql_priv.h: Refactoring, separate lex_input_stream from st_lex. sql/slave.cc: Refactoring, separate lex_input_stream from st_lex. sql/sp.cc: Refactoring, separate lex_input_stream from st_lex. sql/sp_head.cc: Refactoring, separate lex_input_stream from st_lex. sql/sp_head.h: Refactoring, separate lex_input_stream from st_lex. sql/sql_class.cc: Refactoring, separate lex_input_stream from st_lex. sql/sql_class.h: Refactoring, separate lex_input_stream from st_lex. sql/sql_lex.cc: Refactoring, separate lex_input_stream from st_lex. sql/sql_lex.h: Refactoring, separate lex_input_stream from st_lex. sql/sql_parse.cc: Refactoring, separate lex_input_stream from st_lex. sql/sql_prepare.cc: Refactoring, separate lex_input_stream from st_lex. sql/sql_trigger.cc: Refactoring, separate lex_input_stream from st_lex. sql/sql_view.cc: Refactoring, separate lex_input_stream from st_lex. sql/sql_yacc.yy: Refactoring, separate lex_input_stream from st_lex.	19 years ago

unknown	fa1d637e89	A set of changes aiming to make the Event Scheduler more user-friendly when there are no up-to-date system tables to support it: - initialize the scheduler before reporting "Ready for connections". This ensures that warnings, if any, are printed before "Ready for connections", and this message is not mangled. - do not abort the scheduler if there are no system tables - check the tables once at start up, remember the status and disable the scheduler if the tables are not up to date. If one attempts to use the scheduler with bad tables, issue an error message. - clean up the behaviour of the module under LOCK TABLES and pre-locking mode - make sure implicit commit of Events DDL works as expected. - add more tests Collateral clean ups in the events code. This patch fixes Bug#23631 Events: SHOW VARIABLES doesn't work when mysql.event is damaged mysql-test/r/events.result: Update results. mysql-test/r/events_bugs.result: Update results. mysql-test/r/events_restart_phase1.result: Update results. mysql-test/r/events_restart_phase2.result: Update results. mysql-test/r/events_restart_phase3.result: Update results. mysql-test/r/events_scheduling.result: Update results. mysql-test/r/events_time_zone.result: Update results. mysql-test/t/events.test: Add new tests for tampering with mysql.event and some more tests for sub-statements, LOCK TABLES mode and pre-locking. mysql-test/t/events_bugs.test: Move the non-concurrent part of test for Bug 16420 to this file. mysql-test/t/events_restart_phase1.test: Rewrite events_restart_* tests to take into account that now we check mysql.event table only once, at server startup. mysql-test/t/events_restart_phase2.test: Rewrite events_restart_* tests to take into account that now we check mysql.event table only once, at server startup. mysql-test/t/events_restart_phase3.test: Rewrite events_restart_* tests to take into account that now we check mysql.event table only once, at server startup. mysql-test/t/events_scheduling.test: Add more coverage for event_scheduler global variable. mysql-test/t/events_time_zone.test: Move the non-concurrent part of the tests for Bug 16420 to events_bugs.test sql/event_data_objects.cc: Move update_timing_fields functionality to Event_db_repository.

All the logic of events DDL is handled outside, in Events class please refer to the added test coverage to see how this change affected the behavior of Event Scheduler. Dependency on sp_head.h and sp.h removed. Make this module robust to tweaks with mysql.event table. Move check_system_tables from events.cc to this file sql/event_db_repository.h: Cleanup declarations (remove unused ones, change return type to bool from int). sql/event_queue.cc: Update to adapt to the new start up scheme of the Event Scheduler. sql/event_queue.h: Cleanup declarations. sql/event_scheduler.cc: Make all the error messages uniform: [SEVERITY] Event Scheduler: [user][schema.event] message Using append_identifier for error logging was an overkill - we may need it only if the system character set may have NUL (null character) as part of a valid identifier, this is currently never the case, whereas additional quoting did not look nice in the log. sql/event_scheduler.h: Cleanup the headers. sql/events.cc: Use a different start up procedure of Event Scheduler: - at start up, try to check the system tables first. If they are not up-to-date, disable the scheduler. - try to load all the active events. In case of a load error, abort start up. - do not parse an event on start up. Parsing only gives some information about event validity, but far not all. Consolidate the business logic of Events DDL in this module. Now opt_event_scheduler may change after start up and thus is protected by LOCK_event_metadata mutex. sql/events.h: Use all-static-data-members approach to implement Singleton pattern. sql/mysqld.cc: New invocation scheme of Events. Move some logic to events.cc. Initialize the scheduler before reporting "Ready for connections". sql/set_var.cc: Clean up sys_var_thd_sql_mode::symbolic_mode_representation to work with a LEX_STRING. Move more logic related to @@events_scheduler global variable to Events module. sql/set_var.h: Update declarations. sql/share/errmsg.txt: If someone tampered with mysql.event table after the server has started we no longer give him/her a complete report what was actually broken. Do not send the user to look at the error log in such case, as there is nothing there (check_table_intact is not executed). sql/sp_head.cc: Update to a new declaration of sys_var_thd_sql_mode::symbolic_mode_representation sql/sql_db.cc: New invocation scheme of Events module. sql/sql_parse.cc: Move more logic to Events module. Make sure that we are consistent in the way access rights are checked for Events DDL: always after committing the current transaction and checking the system tables. sql/sql_show.cc: Update to the new declarations of sys_var_thd_sql_mode::symbolic_mode_representation sql/sql_test.cc: New invocation scheme of events. sql/table.cc: mysql.event is a system table.

unknown	7e08016a91	Fix for BUG#27337: Privileges are not properly restored. The problem was that THD::db_access variable was not restored after database switch in stored-routine-execution code. The fix is to restore THD::db_access in this case. Unfortunately, this fix requires additional changes, because in prepare_schema_table(), called on the parsing stage, we checked privileges. That was wrong according to our design, but this flaw haven't struck so far, because it was masked. All privilege checkings must be done on the execution stage in order to be compatible with prepared statements and stored routines. So, this patch also contains patch for prepare_schema_table(), which moves the checkings to the execution phase. mysql-test/r/grant.result: Updated result file. mysql-test/t/grant.test: Added test case for BUG#27337. sql/mysql_priv.h: Added function declaration. sql/sql_db.cc: Fix for BUG#27337 -- set THD::db_access even if we're called from stored-routine-execution code. sql/sql_parse.cc: Split prepare_schema_table() into two functions: - prepare_schema_table(), which is called from the parser (parsing stage); - check_show_access(), which is called on the execution stage. sql/sql_show.cc: Ignore schema_select_lex member if its table is NULL.	19 years ago
unknown	adaf162bc2	WL#3464: Add replication event to denote gap in replication Adding an event that can be used to denote that an incident occured on the master. The event can be used to denote a gap in the replication stream, but can also be used to denote other incidents.

The function will also rotate the binary log after generating an incident event to get a fresh binary log. client/Makefile.am: Adding file rpl_constants.h with constants for replication. mysql-test/extra/binlog_tests/binlog.test: Binlog position change mysql-test/extra/binlog_tests/binlog_insert_delayed.test: Binlog position change mysql-test/extra/binlog_tests/ctype_cp932_binlog.test: Binlog position change mysql-test/extra/binlog_tests/ctype_ucs_binlog.test: Binlog position change mysql-test/extra/binlog_tests/mix_innodb_myisam_binlog.test: Binlog position change mysql-test/extra/rpl_tests/rpl_deadlock.test: Binlog position change mysql-test/extra/rpl_tests/rpl_log.test: Binlog position change mysql-test/extra/rpl_tests/rpl_multi_query.test: Binlog position change mysql-test/extra/rpl_tests/rpl_row_charset.test: Binlog position change mysql-test/extra/rpl_tests/rpl_row_sp002.test: Binlog position change mysql-test/extra/rpl_tests/rpl_row_sp003.test: Binlog position change mysql-test/extra/rpl_tests/rpl_stm_charset.test: Binlog position change mysql-test/include/show_binlog_events.inc: Binlog position change mysql-test/r/binlog_row_binlog.result: Result change mysql-test/r/binlog_row_ctype_ucs.result: Result change mysql-test/r/binlog_row_insert_select.result: Result change mysql-test/r/binlog_row_mix_innodb_myisam.result: Result change mysql-test/r/binlog_stm_binlog.result: Result change mysql-test/r/binlog_stm_ctype_ucs.result: Result change mysql-test/r/binlog_stm_insert_select.result: Result change mysql-test/r/binlog_stm_mix_innodb_myisam.result: Result change mysql-test/r/ctype_cp932_binlog_row.result: Result change mysql-test/r/ctype_cp932_binlog_stm.result: Result change mysql-test/r/flush_block_commit_notembedded.result: Result change mysql-test/r/rpl_000015.result: Result change mysql-test/r/rpl_change_master.result: Result change mysql-test/r/rpl_deadlock_innodb.result: Result change mysql-test/r/rpl_flushlog_loop.result: Result change mysql-test/r/rpl_loaddata.result: Result change mysql-test/r/rpl_loaddata_s.result: Result change mysql-test/r/rpl_log_pos.result: Result change mysql-test/r/rpl_ndb_charset.result: Result change mysql-test/r/rpl_ndb_log.result: Result change mysql-test/r/rpl_ndb_multi.result: Result change mysql-test/r/rpl_rbr_to_sbr.result: Result change mysql-test/r/rpl_rotate_logs.result: Result change mysql-test/r/rpl_row_basic_11bugs.result: Result change mysql-test/r/rpl_row_charset.result: Result change mysql-test/r/rpl_row_create_table.result: Result change mysql-test/r/rpl_row_delayed_ins.result: Result change mysql-test/r/rpl_row_drop.result: Result change mysql-test/r/rpl_row_flsh_tbls.result: Result change mysql-test/r/rpl_row_inexist_tbl.result: Result change mysql-test/r/rpl_row_log.result: Result change mysql-test/r/rpl_row_log_innodb.result: Result change mysql-test/r/rpl_row_max_relay_size.result: Result change mysql-test/r/rpl_row_reset_slave.result: Result change mysql-test/r/rpl_row_until.result: Result change mysql-test/r/rpl_server_id1.result: Result change mysql-test/r/rpl_server_id2.result: Result change mysql-test/r/rpl_sp.result: Result change mysql-test/r/rpl_stm_charset.result: Result change mysql-test/r/rpl_stm_flsh_tbls.result: Result change mysql-test/r/rpl_stm_log.result: Result change mysql-test/r/rpl_stm_max_relay_size.result: Result change mysql-test/r/rpl_stm_multi_query.result: Result change mysql-test/r/rpl_stm_reset_slave.result: Result change mysql-test/r/rpl_stm_until.result: Result change mysql-test/r/rpl_switch_stm_row_mixed.result: Result change mysql-test/r/rpl_truncate_2myisam.result: Result change mysql-test/r/rpl_truncate_3innodb.result: Result change mysql-test/r/rpl_truncate_7ndb.result: Result change mysql-test/r/user_var-binlog.result: Result change mysql-test/t/binlog_row_mix_innodb_myisam.test: Binlog position change mysql-test/t/binlog_stm_mix_innodb_myisam.test: Binlog position change mysql-test/t/ctype_cp932_binlog_stm.test: Binlog position change mysql-test/t/mysqlbinlog.test: Binlog position change mysql-test/t/mysqlbinlog2.test: Binlog position change mysql-test/t/rpl_loaddata_s.test: Binlog position change mysql-test/t/rpl_log_pos.test: Binlog position change mysql-test/t/rpl_row_basic_11bugs.test: Binlog position change mysql-test/t/rpl_row_create_table.test: Binlog position change mysql-test/t/rpl_row_flsh_tbls.test: Binlog position change mysql-test/t/rpl_row_mysqlbinlog.test: Binlog position change mysql-test/t/rpl_sp.test: Binlog position change mysql-test/t/rpl_stm_flsh_tbls.test: Binlog position change mysql-test/t/rpl_switch_stm_row_mixed.test: Binlog position change mysql-test/t/user_var-binlog.test: Binlog position change sql/Makefile.am: Adding file rpl_constants.h with constants for replication. sql/log_event.cc: Changing prototype for read_str() to be const-correct and changing code to match that.

unknown	6a594ffd18	Fix for BUG#25082: default database change on trigger execution breaks replication. When a stored routine is executed, we switch current database to the database, in which the routine has been created. When the stored routine finishes, we switch back to the original database. The problem was that if the original database does not exist (anymore) after routine execution, we raised an error. The fix is to report a warning, and switch to the NULL database. mysql-test/r/sp.result: Updated result file. mysql-test/t/sp.test: Added test case for BUG#25082. sql/mysql_priv.h: 1.
