unknown	a9ce138822	Bug #27816 : Log tables ran with partitions crashes the server when logging is enabled. Currently the partition engine doesn't allow log tables to be partitioned. But this was not checked and the server crashed. Fixed by adding a check in ALTER TABLE to disable partitioning the log tables. While working on the cause of the problem improved the way the log thread structures are initialized before opening the log tables. mysql-test/r/partition.result: Bug #27816: test case mysql-test/t/partition.test: Bug #27816: test case sql/log.cc: Bug #27816: optional Improved initialization of the log threads before opening the log table. Remedies problems that arise from open_table() et. al. depending on a correctly initialized thd. Prerequisite for handling partitioned log tables : they call the parser while reading the .frm file. sql/sql_table.cc: Bug #27816: throw an error when paritioning the log tables : not supported by the partition engine.	19 years ago

unknown	fce63f8f3f	Bug #28488 : Incorrect information in file: './test/t1_test#.frm' While executing ALTER TABLE ... PARTITION the server uses a temporary "shadow" table to create the updated table. This shadow table then gets renamed as the original table. The shadow table was not prefixed with the special prefix that marks temporary tables so it was picked up by SHOW TABLE STATUS. Fixed by isolating the code to create the shadow table name in a separate function and prefixing the shadow table name with the special prefix to exclude it from the list of user tables. See bug 18775 and WL1324 for details. mysql-test/r/partition.result: Bug #28488: test case mysql-test/t/partition.test: Bug #28488: test case sql/mysql_priv.h: Bug #28488: prefix shadow file with the temp prefix sql/sql_partition.cc: Bug #28488: prefix shadow file with the temp prefix sql/sql_table.cc: Bug #28488: prefix shadow file with the temp prefix	19 years ago

unknown	cfd1e67ae4	Bug#28427: Columns were renamed instead of moving by ALTER TABLE. To avoid unnecessary work the mysql_alter_table function takes the list of table fields and applies all changes to it (drops/moves/renames/etc). Then this function compares the new list and the old one. If the changes require only .frm to be modified then the actual data isn't copied. To detect changes all columns attributes but names are compared. When a column has been moved and has replaced another column with the same attributes except name the mysql_alter_table function wrongly decides that two fields has been just renamed. As a result the data from the moved column and from all columns after it is not copied. Now the mysql_alter_table function forces table data copying by setting the need_copy_table flag when it finds a moved column. The flag is set at the stage when the modified fields are created. sql/sql_table.cc: Bug#28427: Columns were renamed instead of moving by ALTER TABLE. Now the mysql_alter_table function forces table data copying by setting the need_copy_table flag when it finds a moved column.

unknown	e42439af33	Bug #28477 innodb assertion and crash during alter table to add/drop partition. The bug was repeated on MyISAM tables, so isn't InnoDB specific. Reason of the bug is that partition-related members of TABLE_SHARE wasn't properly updated after ALTER command. So if other thread doesn't reread frm file, and just uses cached SHARE, it uses wrong data sql/sql_table.cc: Bug #28477 innodb assertion and crash during alter table to add/drop partition. keep share members updated after table modification sql/table.cc: Bug #28477 innodb assertion and crash during alter table to add/drop partition. share->partition_info_buffer_size initialization added sql/table.h: Bug #28477 innodb assertion and crash during alter table to add/drop partition. partition_info_buffer_size declared in st_table_share to store the size of the memory available for partition_info	19 years ago

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. Update declarations to use LEX::alter_info instead of these two members. Remove declarations of mysql_add_index, mysql_drop_index. sql/sql_class.cc: Implement deep copy constructors. sql/sql_class.h: Implement (almost) deep copy constructors for key_part_spec, Alter_drop, Alter_column, Key, foreign_key. 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 ...

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 ...

unknown	f3b78f34e5	Bug#27507: Wrong DATETIME value was allowed by ALTER TABLE in the NO_ZERO_DATE mode. When a new DATE/DATETIME field without default value is being added by the ALTER TABLE the '0000-00-00' value is used as the default one. But it wasn't checked whether such value was allowed by the set sql mode. Due to this '0000-00-00' values was allowed for DATE/DATETIME fields even in the NO_ZERO_DATE mode. Now the mysql_alter_table() function checks whether the '0000-00-00' value is allowed for DATE/DATETIME fields by the set sql mode. The new error_if_not_empty flag is used in the mysql_alter_table() function to indicate that it should abort if the table being altered isn't empty. The new new_datetime_field field is used in the mysql_alter_table() function for error throwing purposes. The new error_if_not_empty parameter is added to the copy_data_between_tables() function to indicate the it should return error if the source table isn't empty. mysql-test/t/alter_table.test: Added a test case for the bug#27507: Wrong DATETIME value was allowed by ALTER TABLE in the NO_ZERO_DATE mode. mysql-test/r/alter_table.result: Added a test case for the bug#27507: Wrong DATETIME value was allowed by ALTER TABLE in the NO_ZERO_DATE mode. sql/sql_table.cc: Bug#27507: Wrong DATETIME value was allowed by ALTER TABLE in the NO_ZERO_DATE mode.

unknown	1a60685cba	Patch changing how ALTER TABLE implementation handles table locking and invalidation in the most general case (non-temporary table and not simple RENAME or ENABLE/DISABLE KEYS or partitioning command). See comment for sql/sql_table.cc for more information. These changes are prerequisite for 5.1 version of fix for bug #23667 "CREATE TABLE LIKE is not isolated from alteration by other connections" mysql-test/include/mix1.inc: Extended coverage for behavior of ALTER TABLE statement under LOCK TABLES, which should be consistent across all platforms and for all engines. mysql-test/r/alter_table-big.result: Changed test for bug #25044 to use @@debug and injected sleeps infrastructure. Extended test coverage for ALTER TABLE's behavior under concurrency. mysql-test/r/alter_table.result: Extended coverage for behavior of ALTER TABLE statement under LOCK TABLES, which should be consistent across all platforms and for all engines. mysql-test/r/innodb_mysql.result: Extended coverage for behavior of ALTER TABLE statement under LOCK TABLES, which should be consistent across all platforms and for all engines. mysql-test/t/alter_table-big.test: Changed test for bug #25044 to use @@debug and injected sleeps infrastructure. Extended test coverage for ALTER TABLE's behavior under concurrency. mysql-test/t/alter_table.test: Extended coverage for behavior of ALTER TABLE statement under LOCK TABLES, which should be consistent across all platforms and for all engines. sql/mysql_priv.h: Made functions reopen_table() and close_handle_and_leave_table_as_lock() available outside of sql_base.cc file. Changed close_data_tables() in such way that after closing handler for the table it leaves TABLE object for it in table cache not as placeholder for ordinary name-lock but as placeholder for an exclusive name-lock. Renamed this routine to close_data_files_and_morph_locks(). sql/sql_base.cc: Made functions reopen_table() and close_handle_and_leave_table_as_lock() available outside of sql_base.cc file. Changed close_data_tables() in such way that after closing handler for the table it leaves TABLE object for it in table cache not as placeholder for ordinary name-lock but as placeholder for an exclusive name-lock. Renamed this routine to close_data_files_and_morph_locks(). Also adjusted it so it can work properly not only in LOCK TABLES mode. sql/sql_table.cc: Changed the way in which ALTER TABLE implementation handles table locking and invalidation in the most general case (non-temporary table and not simple RENAME or ENABLE/DISABLE KEYS or partitioning command) Now after preparing new version of the table we: 1) Wait until all other threads close old version of table. 2) Close instances of table open by this thread and replace them with exclusive name-locks. 3) Rename the old table to a temp name, rename the new one to the old name. 4) If we are under LOCK TABLES and don't do ALTER TABLE ... RENAME we reopen new version of table. 5) Write statement to the binary log. 6) If we are under LOCK TABLES and do ALTER TABLE ... RENAME we remove name-locks from list of open tables and table cache. 7) If we are not not under LOCK TABLES we rely on close_thread_tables() call to remove name-locks from table cache and list of open table. Such approach: a) Eliminates possibility for concurrent statement to sneak in and get access to the new version of the table before ALTER TABLE gets logged into binary log. b) Ensures that ALTER TABLE behaves under LOCK TABLES in the same way on all platforms and for all engines (in 5.0 this was not true) c) Preserves nice invariant that if table is open in some connection there is a guarantee that .FRM file for this table exists and is properly named.	19 years ago
unknown	3f0cdbc4cd	Fix for bug #28415 "Some ALTER TABLE statements no longer work under LOCK TABLES" and failures of alter_table.test on Windows which occured after pushing fix for bugs #20662, #20903, #24508, #24738 (various problems with CREATE TABLE SELECT). ALTER TABLE statements which were handled using "fast" alter table optimization were not properly working under LOCK TABLES if table was transactional (for all table types under Windows). Code implementing "fast" version of ALTER TABLE tried to open and lock table using open_ltable() after renaming .FRM files (which corresponds to renaming tables in normal case) in some cases (for transactional tables or on Windows). This caused problems under LOCK TABLES and conflicted with name-lock taken by ALTER TABLE RENAME on target tables. This patch solves this issue by using reopen_name_locked_table() instead of open_ltable(). mysql-test/include/mix1.inc: Added test for bug #28415 "Some ALTER TABLE statements no longer work under LOCK TABLES" and minimal coverage for fast ALTER TABLE behaviour for transactional tables. mysql-test/r/innodb_mysql.result: Added test for bug #28415 "Some ALTER TABLE statements no longer work under LOCK TABLES" and minimal coverage for fast ALTER TABLE behaviour for transactional tables. sql/sql_table.cc: mysql_alter_table(): Fixed handling of transactional tables (and all tables on Windows) by "fast" ALTER TABLE.

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 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
unknown	c5a8245596	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. 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). 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 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). 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 select_create methods 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: 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 ... 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_LIST::create member which marks elements of table list corresponds to the table to be created.

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	86a0ffdd3c	Bug#23233: 0 as LAST_INSERT_ID() after INSERT .. ON DUPLICATE in the NO_AUTO_VALUE_ON_ZERO mode. In the NO_AUTO_VALUE_ON_ZERO mode the table->auto_increment_field_not_null variable is used to indicate that a non-NULL value was specified by the user for an auto_increment column. When an INSERT .. ON DUPLICATE updates the auto_increment field this variable is set to true and stays unchanged for the next insert operation. This makes the next inserted row sometimes wrongly have 0 as the value of the auto_increment field. Now the fill_record() function resets the table->auto_increment_field_not_null variable before filling the record. The table->auto_increment_field_not_null variable is also reset by the open_table() function for a case if we missed some auto_increment_field_not_null handling bug.

The table handler returned its file name extensions in a wrong order. REPAIR TABLE believed it has to use the meta file to create a new table from it. With the fixed order, REPAIR TABLE does now use the data file to create a new table. So REPAIR TABLE ... USE_FRM works well with ARCHIVE engine now.

unknown	4a76ac5fa6	Bug #27395 OPTION_STATUS_NO_TRANS_UPDATE is not preserved at the end of SF() thd->options' OPTION_STATUS_NO_TRANS_UPDATE bit was not restored at the end of SF() invocation, where SF() modified non-ta table. As the result of this artifact it was not possible to detect whether there were any side-effects when top-level query ends. If the top level query table was not modified and the bit is lost there would be no binlogging. Fixed with preserving the bit inside of thd->no_trans_update struct.

unknown	3514500e8d	Bug#17332 - changing key_buffer_size on a running server can crash under load Resizing a key cache while it was in heavy use could crash the server. There were several race conditions. I reworked some of the algorithms to fix the race conditions. No test case. Repeating the crashes requires heavy concurrent load on the key cache. A test script is attached to the bug report. More explanations to the changes are contained in a text file attached to the bug report. include/keycache.h: Bug#17332 - changing key_buffer_size on a running server can crash under load Added KEY_CACHE components in_resize and waiting_for_resize_cnt. mysys/mf_keycache.c: Bug#17332 - changing key_buffer_size on a running server can crash under load Changed resize_key_cache() to not disable the key cache after the flush phase. Changed queue handling to use standard functions. Wake all threads waiting on resize_queue. We can now have read/write threads waiting there (see below). Combined add_to_queue() and the wait loops that were always following it to the new function wait_on_queue(). Combined release_queue() and the condition that was always preceding it to the new function release_whole_queue(). Added code to flag and respect the exceptional situation BLOCK_IN_EVICTION. Rewrote the resize branch of find_key_block(). Added code to the eviction handling in find_key_block() to catch more exceptional cases. Changed key_cache_read(), key_cache_insert() and key_cache_write() so that they lock keycache->cache_lock whenever the key cache is initialized. Checking for a disabled cache and incrementing and decrementing the "resize counter" is always done within the lock. Locking and unlocking as well as counting the "resize counter" is now done once outside the loop. All three functions can now handle a NULL return from find_key_block. This happens in the flush phase of a resize and demands direct file I/O. Care is taken for secondary requests (PAGE_WAIT_TO_BE_READ) to wait in any case. Moved block status changes behind the copying of buffer data. key_cache_insert() does now read the block if the caller did supply less data than a full cache block. key_cache_write() does now take care of parallel running flushes (BLOCK_FOR_UPDATE, BLOCK_IN_FLUSHWRITE). Changed free_block() to un-initialize block variables in the correct order and respect an exceptional BLOCK_IN_EVICTION state. Changed flushing to take care for parallel running writes. Changed flushing to avoid freeing blocks in eviction. Changed flushing to consider that parallel writes can move blocks from the file_blocks hash to the changed_blocks hash. Changed flushing to take care for other parallel flushes. Changed flushing to assure that it ends with everything flushed. Added some comments and debugging statements. ;-) mysys/my_static.c: Bug#17332 - changing key_buffer_size on a running server can crash under load Removed an unused global variable. sql/handler.cc: Bug#17332 - changing key_buffer_size on a running server can crash under load Changed types of local variables to match their use for init_key_cache(). sql/sql_table.cc: Bug#17332 - changing key_buffer_size on a running server can crash under load Changed TL_READ to TL_READ_NO_INSERT in mysql_preload_keys. storage/myisam/ha_myisam.cc: Bug#17332 - changing key_buffer_size on a running server can crash under load Moved an automatic (stack) variable to the scope where it is used. storage/myisam/mi_preload.c: Bug#17332 - changing key_buffer_size on a running server can crash under load Added some preliminary code to - allow LOAD INDEX to load indexes of different block size, - align load chunks to key cache blocks.	19 years ago
