MDEV-11227 - mysqlimport -l doesn't issue UNLOCK TABLES Implementation of MDEV-7660 introduced unwanted incompatible change: modifications under LOCK TABLES with autocommit enabled are rolled back on disconnect. Previously everything was committed, because LOCK TABLES didn't adjust autocommit setting. This patch restores original behavior by reverting some changes done in MDEV-7660: - sql/sql_parse.cc: do not reset autocommit on LOCK TABLES - sql/sql_base.cc: do not set autocommit on UNLOCK TABLES - test cases: main.lock_tables_lost_commit, main.partition_explicit_prune, rpl.rpl_switch_stm_row_mixed, tokudb.nested_txn_implicit_commit, tokudb_bugs.db806 But it makes InnoDB tables under LOCK TABLES ... READ [LOCAL] not protected against DML. To restore protection some changes from WL#6671 were merged, specifically MDL_SHARED_READ_ONLY and test cases. WL#6671 merge highlights: - Not all tests merged. - In MySQL LOCK TABLES ... READ acquires MDL_SHARED_READ_ONLY for all engines, in MariaDB MDL_SHARED_READ is always acquired first and then upgraded to MDL_SHARED_READ_ONLY for InnoDB only. - The above allows us to omit MDL_SHARED_WRITE_LOW_PRIO implementation in MariaDB, which is rather useless with InnoDB. In MySQL it is needed to preserve locking behavior between low priority writes and LOCK TABLES ... READ for non-InnoDB engines (covered by sys_vars.sql_low_priority_updates_func). - Omitted HA_NO_READ_LOCAL_LOCK, we rely on lock_count() instead. - Omitted "piglets": in MariaDB stream of DML against InnoDB table may lead to concurrent LOCK TABLES ... READ starvation. - HANDLER ... OPEN acquires MDL_SHARED_READ instead of MDL_SHARED in MariaDB. - Omitted SNRW->X MDL lock upgrade for IMPORT/DISCARD TABLESPAECE under LOCK TABLES. - Omitted strong locks for views, triggers and SP under LOCK TABLES. - Omitted IX schema lock for LOCK TABLES READ. - Omitted deadlock weight juggling for LOCK TABLES.

MDEV-11227 - mysqlimport -l doesn't issue UNLOCK TABLES Implementation of MDEV-7660 introduced unwanted incompatible change: modifications under LOCK TABLES with autocommit enabled are rolled back on disconnect. Previously everything was committed, because LOCK TABLES didn't adjust autocommit setting. This patch restores original behavior by reverting some changes done in MDEV-7660: - sql/sql_parse.cc: do not reset autocommit on LOCK TABLES - sql/sql_base.cc: do not set autocommit on UNLOCK TABLES - test cases: main.lock_tables_lost_commit, main.partition_explicit_prune, rpl.rpl_switch_stm_row_mixed, tokudb.nested_txn_implicit_commit, tokudb_bugs.db806 But it makes InnoDB tables under LOCK TABLES ... READ [LOCAL] not protected against DML. To restore protection some changes from WL#6671 were merged, specifically MDL_SHARED_READ_ONLY and test cases. WL#6671 merge highlights: - Not all tests merged. - In MySQL LOCK TABLES ... READ acquires MDL_SHARED_READ_ONLY for all engines, in MariaDB MDL_SHARED_READ is always acquired first and then upgraded to MDL_SHARED_READ_ONLY for InnoDB only. - The above allows us to omit MDL_SHARED_WRITE_LOW_PRIO implementation in MariaDB, which is rather useless with InnoDB. In MySQL it is needed to preserve locking behavior between low priority writes and LOCK TABLES ... READ for non-InnoDB engines (covered by sys_vars.sql_low_priority_updates_func). - Omitted HA_NO_READ_LOCAL_LOCK, we rely on lock_count() instead. - Omitted "piglets": in MariaDB stream of DML against InnoDB table may lead to concurrent LOCK TABLES ...

Implemntation done by removing orig_sql_command and moving logic of SHOW STATUS to mysql_excute_command() This simplifies code and allows us to remove some if statements all over the code.

Added test cases for preceding test This includes all test changes from "Changing all cost calculation to be given in milliseconds" and forwards. Some of the things that caused changes in the result files: - As part of fixing tests, I added 'echo' to some comments to be able to easier find out where things where wrong. - MATERIALIZED has now a higher cost compared to X than before. Because of this some MATERIALIZED types have changed to DEPENDEND SUBQUERY. - Some test cases that required MATERIALIZED to repeat a bug was changed by adding more rows to force MATERIALIZED to happen. - 'Filtered' in SHOW EXPLAIN has in many case changed from 100.00 to something smaller. This is because now filtered also takes into account the smallest possible ref access and filters, even if they where not used. Another reason for 'Filtered' being smaller is that we now also take into account implicit filtering done for subqueries using FIRSTMATCH. (main.subselect_no_exists_to_in) This is caluculated in best_access_path() and stored in records_out. - Table orders has changed because more accurate costs. - 'index' and 'ALL' for small tables has changed to use 'range' or 'ref' because of optimizer_scan_setup_cost. - index can be changed to 'range' as 'range' optimizer assumes we don't have to read the blocks from disk that range optimizer has already read. This can be confusing in the case where there is no obvious where clause but instead there is a hidden 'key_column > NULL' added by the optimizer. (main.subselect_no_exists_to_in) - Scan on primary clustered key does not report 'Using Index' anymore (It's a table scan, not an index scan). - For derived tables, the number of rows is now 100 instead of 2, which can be seen in EXPLAIN. - More tests have "Using index for group by" as the cost of this optimization is now more correct (lower). - A primary key could be preferred for a normal key, even if it would access more rows, as it's faster to do 1 lokoup and 3 'index_next' on a clustered primary key than one lookup trough a secondary. (main.stat_tables_innodb) Notes: - There was a 4.7% more calls to best_extension_by_limited_search() in the main.greedy_optimizer test. However examining the test results it looked that the plans where slightly better (eq_ref where more chained together) so I assume this is ok. - I have verified a few test cases where there was notable/unexpected changes in the plan and in all cases the new optimizer plans where faster.

Fixes bugs: Bug#10210: running SHOW STATUS increments counters it shouldn't Bug#19764: SHOW commands end up in the slow log as table scans mysql-test/r/grant_cache.result: Fixed results after SHOW STATUS doesn't anymore affect status variables mysql-test/r/information_schema.result: Added extra test to cover more code mysql-test/r/query_cache.result: Remove resuts from previous tests mysql-test/r/status.result: Added more tests for testing of last_query_cost and how SHOW STATUS affects status variables. (Bug#10210) mysql-test/r/temp_table.result: Fixed results after SHOW STATUS doesn't anymore affect status variables mysql-test/r/union.result: Fixed results after SHOW STATUS is not logged to slow query log (Bug#19764) mysql-test/t/events_microsec.test: Disable warnings at init mysql-test/t/information_schema.test: Added extra test to cover more code mysql-test/t/query_cache.test: Remove resuts from previous tests mysql-test/t/status.test: Added more tests for testing of last_query_cost and how SHOW STATUS affects status variables. (Bug #10210) sql/mysql_priv.h: Added 'sql_command_flags' sql/sql_class.cc: New function add_diff_to_status(), used to update global status variables when using SHOW STATUS sql/sql_class.h: New function 'fill_information_schema_tables()' (One could not anymore use fill_derived_tables() for this as only_view_structures() is not relevant for information schema tables) Added defines for bit flags in sql_command_flags[] sql/sql_lex.cc: Remove orig_sql_command sql/sql_lex.h: Remove orig_sql_command sql/sql_parse.cc: Rename uc_update_queries -> sql_command_flags. Enhanced 'sql_command_flags' to better classify SQL commands uc_update_queries[] != 0 is changed to (sql_command_flags[] & CF_CHANGES_DATA) lex->orig_sql_command == SQLCOM_END is changed to (sql_command_flags[lex->sql_command] & CF_STATUS_COMMAND) == 0) Simplify incrementing of thd->status_var.com_stat[] as we don't have to do special handling for SHOW commands. Split SQLCOM_SELECT handling in mysql_execute_command() to a separate function. Added special handling of SHOW STATUS commands in mysql_execute_command() and call common SQLCOM_SELECT handling. These changes allows us to easily fix that we save and restore status variables during execution of a SHOW STATUS command. Don't log SHOW STATUS commands to slow query log. This fixes Bug#10210 and Bug#19764 without adding additional 'if' code. (The new code is faster than the original as we now have fewer if's than before) sql/sql_prepare.cc: Clean up prepare-check handling of SQLCOM commands by using sql_command_flags[] This simplifes code and ensures that code works even if someone forgets to put a new status commands into the switch statement. sql/sql_select.cc: Remove special handling of SHOW STATUS. (This is now done in SQLCOM_SHOW_STATUS part in mysql_execute_command()) sql/sql_show.cc: Remove orig_sql_command Only change sql_command during 'open_normal_and_derived_tables()' (for views) and not for the full duration of generating data. Changed 'show status' to use thd->initial_status_var to ensure that the current statement is not affecting the to-be-used values. Use thd->fill_information_schema_tables() instead of 'thd->fill_derived_tables()' as the later wrongly checks the value of sql_command. sql/sql_yacc.yy: Remove usage of orig_sql_command. One side effect of this is that we need to test for cursors if the current command is a SELECT or a SHOW command. sql/structs.h: Updated comment

Added test cases for preceding test This includes all test changes from "Changing all cost calculation to be given in milliseconds" and forwards. Some of the things that caused changes in the result files: - As part of fixing tests, I added 'echo' to some comments to be able to easier find out where things where wrong. - MATERIALIZED has now a higher cost compared to X than before. Because of this some MATERIALIZED types have changed to DEPENDEND SUBQUERY. - Some test cases that required MATERIALIZED to repeat a bug was changed by adding more rows to force MATERIALIZED to happen. - 'Filtered' in SHOW EXPLAIN has in many case changed from 100.00 to something smaller. This is because now filtered also takes into account the smallest possible ref access and filters, even if they where not used. Another reason for 'Filtered' being smaller is that we now also take into account implicit filtering done for subqueries using FIRSTMATCH. (main.subselect_no_exists_to_in) This is caluculated in best_access_path() and stored in records_out. - Table orders has changed because more accurate costs. - 'index' and 'ALL' for small tables has changed to use 'range' or 'ref' because of optimizer_scan_setup_cost. - index can be changed to 'range' as 'range' optimizer assumes we don't have to read the blocks from disk that range optimizer has already read. This can be confusing in the case where there is no obvious where clause but instead there is a hidden 'key_column > NULL' added by the optimizer. (main.subselect_no_exists_to_in) - Scan on primary clustered key does not report 'Using Index' anymore (It's a table scan, not an index scan). - For derived tables, the number of rows is now 100 instead of 2, which can be seen in EXPLAIN. - More tests have "Using index for group by" as the cost of this optimization is now more correct (lower). - A primary key could be preferred for a normal key, even if it would access more rows, as it's faster to do 1 lokoup and 3 'index_next' on a clustered primary key than one lookup trough a secondary. (main.stat_tables_innodb) Notes: - There was a 4.7% more calls to best_extension_by_limited_search() in the main.greedy_optimizer test. However examining the test results it looked that the plans where slightly better (eq_ref where more chained together) so I assume this is ok. - I have verified a few test cases where there was notable/unexpected changes in the plan and in all cases the new optimizer plans where faster. (main.greedy_optimizer and some others)

MDEV-9101 Limit size of created disk temporary files and tables Two new variables added: - max_tmp_space_usage : Limits the the temporary space allowance per user - max_total_tmp_space_usage: Limits the temporary space allowance for all users. New status variables: tmp_space_used & max_tmp_space_used New field in information_schema.process_list: TMP_SPACE_USED The temporary space is counted for: - All SQL level temporary files. This includes files for filesort, transaction temporary space, analyze, binlog_stmt_cache etc. It does not include engine internal temporary files used for repair, alter table, index pre sorting etc. - All internal on disk temporary tables created as part of resolving a SELECT, multi-source update etc. Special cases: - When doing a commit, the last flush of the binlog_stmt_cache will not cause an error even if the temporary space limit is exceeded. This is to avoid giving errors on commit. This means that a user can temporary go over the limit with up to binlog_stmt_cache_size. Noteworthy issue: - One has to be careful when using small values for max_tmp_space_limit together with binary logging and with non transactional tables. If a the binary log entry for the query is bigger than binlog_stmt_cache_size and one hits the limit of max_tmp_space_limit when flushing the entry to disk, the query will abort and the binary log will not contain the last changes to the table. This will also stop the slave! This is also true for all Aria tables as Aria cannot do rollback (except in case of crashes)! One way to avoid it is to use @@binlog_format=statement for queries that updates a lot of rows. Implementation: - All writes to temporary files or internal temporary tables, that increases the file size, are routed through temp_file_size_cb_func() which updates and checks the temp space usage. - Most of the temporary file monitoring is done inside IO_CACHE. Temporary file monitoring is done inside the Aria engine. - MY_TRACK and MY_TRACK_WITH_LIMIT are new flags for ini_io_cache(). MY_TRACK means that we track the file usage. TRACK_WITH_LIMIT means that we track the file usage and we give an error if the limit is breached. This is used to not give an error on commit when binlog_stmp_cache is flushed. - global_tmp_space_used contains the total tmp space used so far. This is needed quickly check against max_total_tmp_space_usage. - Temporary space errors are using EE_LOCAL_TMP_SPACE_FULL and handler errors are using HA_ERR_LOCAL_TMP_SPACE_FULL. This is needed until we move general errors to it's own error space so that they cannot conflict with system error numbers. - Return value of my_chsize() and mysql_file_chsize() has changed so that -1 is returned in the case my_chsize() could not decrease the file size (very unlikely and will not happen on modern systems). All calls to _chsize() are updated to check for > 0 as the error condition. - At the destruction of THD we check that THD::tmp_file_space == 0 - At server end we check that global_tmp_space_used == 0 - As a precaution against errors in the tmp_space_used code, one can set max_tmp_space_usage and max_total_tmp_space_usage to 0 to disable the tmp space quota errors. - truncate_io_cache() function added. - Aria tables using static or dynamic row length are registered in 8K increments to avoid some calls to update_tmp_file_size(). Other things: - Ensure that all handler errors are registered. Before, some engine errors could be printed as "Unknown error". - Fixed bug in filesort() that causes a assert if there was an error when writing to the temporay file. - Fixed that compute_window_func() now takes into account write errors. - In case of parallel replication, rpl_group_info::cleanup_context() could call trans_rollback() with thd->error set, which would cause an assert. Fixed by resetting the error before calling trans_rollback(). - Fixed bug in subselect3.inc which caused following test to use heap tables with low value for max_heap_table_size - Fixed bug in sql_expression_cache where it did not overflow heap table to Aria table. - Added Max_tmp_disk_space_used to slow query log. - Fixed some bugs in log_slow_innodb.test

One side effect of this is that we need to test for cursors if the current command is a SELECT or a SHOW command. sql/structs.h: Updated comment

MDEV-9101 Limit size of created disk temporary files and tables Two new variables added: - max_tmp_space_usage : Limits the the temporary space allowance per user - max_total_tmp_space_usage: Limits the temporary space allowance for all users. New status variables: tmp_space_used & max_tmp_space_used New field in information_schema.process_list: TMP_SPACE_USED The temporary space is counted for: - All SQL level temporary files. This includes files for filesort, transaction temporary space, analyze, binlog_stmt_cache etc. It does not include engine internal temporary files used for repair, alter table, index pre sorting etc. - All internal on disk temporary tables created as part of resolving a SELECT, multi-source update etc. Special cases: - When doing a commit, the last flush of the binlog_stmt_cache will not cause an error even if the temporary space limit is exceeded. This is to avoid giving errors on commit. This means that a user can temporary go over the limit with up to binlog_stmt_cache_size. Noteworthy issue: - One has to be careful when using small values for max_tmp_space_limit together with binary logging and with non transactional tables. If a the binary log entry for the query is bigger than binlog_stmt_cache_size and one hits the limit of max_tmp_space_limit when flushing the entry to disk, the query will abort and the binary log will not contain the last changes to the table. This will also stop the slave! This is also true for all Aria tables as Aria cannot do rollback (except in case of crashes)! One way to avoid it is to use @@binlog_format=statement for queries that updates a lot of rows. Implementation: - All writes to temporary files or internal temporary tables, that increases the file size, are routed through temp_file_size_cb_func() which updates and checks the temp space usage. - Most of the temporary file monitoring is done inside IO_CACHE. Temporary file monitoring is done inside the Aria engine. - MY_TRACK and MY_TRACK_WITH_LIMIT are new flags for ini_io_cache(). MY_TRACK means that we track the file usage. TRACK_WITH_LIMIT means that we track the file usage and we give an error if the limit is breached. This is used to not give an error on commit when binlog_stmp_cache is flushed. - global_tmp_space_used contains the total tmp space used so far. This is needed quickly check against max_total_tmp_space_usage. - Temporary space errors are using EE_LOCAL_TMP_SPACE_FULL and handler errors are using HA_ERR_LOCAL_TMP_SPACE_FULL. This is needed until we move general errors to it's own error space so that they cannot conflict with system error numbers. - Return value of my_chsize() and mysql_file_chsize() has changed so that -1 is returned in the case my_chsize() could not decrease the file size (very unlikely and will not happen on modern systems). All calls to _chsize() are updated to check for > 0 as the error condition. - At the destruction of THD we check that THD::tmp_file_space == 0 - At server end we check that global_tmp_space_used == 0 - As a precaution against errors in the tmp_space_used code, one can set max_tmp_space_usage and max_total_tmp_space_usage to 0 to disable the tmp space quota errors. - truncate_io_cache() function added. - Aria tables using static or dynamic row length are registered in 8K increments to avoid some calls to update_tmp_file_size(). Other things: - Ensure that all handler errors are registered. Before, some engine errors could be printed as "Unknown error". - Fixed bug in filesort() that causes a assert if there was an error when writing to the temporay file. - Fixed that compute_window_func() now takes into account write errors. - In case of parallel replication, rpl_group_info::cleanup_context() could call trans_rollback() with thd->error set, which would cause an assert. Fixed by resetting the error before calling trans_rollback(). - Fixed bug in subselect3.inc which caused following test to use heap tables with low value for max_heap_table_size - Fixed bug in sql_expression_cache where it did not overflow heap table to Aria table. - Added Max_tmp_disk_space_used to slow query log. - Fixed some bugs in log_slow_innodb.test

SHOW STATUS does not anymore change local status variables (except com_show_status). Global status variables are still updated. SHOW STATUS are not anymore put in slow query log because of no index usage. Implemntation done by removing orig_sql_command and moving logic of SHOW STATUS to mysql_excute_command() This simplifies code and allows us to remove some if statements all over the code. Upgraded uc_update_queries[] to sql_command_flags and added more bitmaps to better categorize commands. This allowed some overall simplifaction when testing sql_command. Fixes bugs: Bug#10210: running SHOW STATUS increments counters it shouldn't Bug#19764: SHOW commands end up in the slow log as table scans mysql-test/r/grant_cache.result: Fixed results after SHOW STATUS doesn't anymore affect status variables mysql-test/r/information_schema.result: Added extra test to cover more code mysql-test/r/query_cache.result: Remove resuts from previous tests mysql-test/r/status.result: Added more tests for testing of last_query_cost and how SHOW STATUS affects status variables.

Split SQLCOM_SELECT handling in mysql_execute_command() to a separate function. Added special handling of SHOW STATUS commands in mysql_execute_command() and call common SQLCOM_SELECT handling. These changes allows us to easily fix that we save and restore status variables during execution of a SHOW STATUS command. Don't log SHOW STATUS commands to slow query log. This fixes Bug#10210 and Bug#19764 without adding additional 'if' code. (The new code is faster than the original as we now have fewer if's than before) sql/sql_prepare.cc: Clean up prepare-check handling of SQLCOM commands by using sql_command_flags[] This simplifes code and ensures that code works even if someone forgets to put a new status commands into the switch statement. sql/sql_select.cc: Remove special handling of SHOW STATUS.

All calls to _chsize() are updated to check for > 0 as the error condition. - At the destruction of THD we check that THD::tmp_file_space == 0 - At server end we check that global_tmp_space_used == 0 - As a precaution against errors in the tmp_space_used code, one can set max_tmp_space_usage and max_total_tmp_space_usage to 0 to disable the tmp space quota errors. - truncate_io_cache() function added. - Aria tables using static or dynamic row length are registered in 8K increments to avoid some calls to update_tmp_file_size(). Other things: - Ensure that all handler errors are registered. Before, some engine errors could be printed as "Unknown error". - Fixed bug in filesort() that causes a assert if there was an error when writing to the temporay file. - Fixed that compute_window_func() now takes into account write errors. - In case of parallel replication, rpl_group_info::cleanup_context() could call trans_rollback() with thd->error set, which would cause an assert. Fixed by resetting the error before calling trans_rollback(). - Fixed bug in subselect3.inc which caused following test to use heap tables with low value for max_heap_table_size - Fixed bug in sql_expression_cache where it did not overflow heap table to Aria table. - Added Max_tmp_disk_space_used to slow query log. - Fixed some bugs in log_slow_innodb.test

SHOW STATUS does not anymore change local status variables (except com_show_status). Global status variables are still updated. SHOW STATUS are not anymore put in slow query log because of no index usage. Implemntation done by removing orig_sql_command and moving logic of SHOW STATUS to mysql_excute_command() This simplifies code and allows us to remove some if statements all over the code. Upgraded uc_update_queries[] to sql_command_flags and added more bitmaps to better categorize commands. This allowed some overall simplifaction when testing sql_command. Fixes bugs: Bug#10210: running SHOW STATUS increments counters it shouldn't Bug#19764: SHOW commands end up in the slow log as table scans mysql-test/r/grant_cache.result: Fixed results after SHOW STATUS doesn't anymore affect status variables mysql-test/r/information_schema.result: Added extra test to cover more code mysql-test/r/query_cache.result: Remove resuts from previous tests mysql-test/r/status.result: Added more tests for testing of last_query_cost and how SHOW STATUS affects status variables. (Bug#10210) mysql-test/r/temp_table.result: Fixed results after SHOW STATUS doesn't anymore affect status variables mysql-test/r/union.result: Fixed results after SHOW STATUS is not logged to slow query log (Bug#19764) mysql-test/t/events_microsec.test: Disable warnings at init mysql-test/t/information_schema.test: Added extra test to cover more code mysql-test/t/query_cache.test: Remove resuts from previous tests mysql-test/t/status.test: Added more tests for testing of last_query_cost and how SHOW STATUS affects status variables. (Bug #10210) sql/mysql_priv.h: Added 'sql_command_flags' sql/sql_class.cc: New function add_diff_to_status(), used to update global status variables when using SHOW STATUS sql/sql_class.h: New function 'fill_information_schema_tables()' (One could not anymore use fill_derived_tables() for this as only_view_structures() is not relevant for information schema tables) Added defines for bit flags in sql_command_flags[] sql/sql_lex.cc: Remove orig_sql_command sql/sql_lex.h: Remove orig_sql_command sql/sql_parse.cc: Rename uc_update_queries -> sql_command_flags. Enhanced 'sql_command_flags' to better classify SQL commands uc_update_queries[] != 0 is changed to (sql_command_flags[] & CF_CHANGES_DATA) lex->orig_sql_command == SQLCOM_END is changed to (sql_command_flags[lex->sql_command] & CF_STATUS_COMMAND) == 0) Simplify incrementing of thd->status_var.com_stat[] as we don't have to do special handling for SHOW commands. Split SQLCOM_SELECT handling in mysql_execute_command() to a separate function. Added special handling of SHOW STATUS commands in mysql_execute_command() and call common SQLCOM_SELECT handling. These changes allows us to easily fix that we save and restore status variables during execution of a SHOW STATUS command. Don't log SHOW STATUS commands to slow query log. This fixes Bug#10210 and Bug#19764 without adding additional 'if' code. (The new code is faster than the original as we now have fewer if's than before) sql/sql_prepare.cc: Clean up prepare-check handling of SQLCOM commands by using sql_command_flags[] This simplifes code and ensures that code works even if someone forgets to put a new status commands into the switch statement. sql/sql_select.cc: Remove special handling of SHOW STATUS. (This is now done in SQLCOM_SHOW_STATUS part in mysql_execute_command()) sql/sql_show.cc: Remove orig_sql_command Only change sql_command during 'open_normal_and_derived_tables()' (for views) and not for the full duration of generating data. Changed 'show status' to use thd->initial_status_var to ensure that the current statement is not affecting the to-be-used values. Use thd->fill_information_schema_tables() instead of 'thd->fill_derived_tables()' as the later wrongly checks the value of sql_command. sql/sql_yacc.yy: Remove usage of orig_sql_command. One side effect of this is that we need to test for cursors if the current command is a SELECT or a SHOW command. sql/structs.h: Updated comment

MDEV-9101 Limit size of created disk temporary files and tables Two new variables added: - max_tmp_space_usage : Limits the the temporary space allowance per user - max_total_tmp_space_usage: Limits the temporary space allowance for all users. New status variables: tmp_space_used & max_tmp_space_used New field in information_schema.process_list: TMP_SPACE_USED The temporary space is counted for: - All SQL level temporary files. This includes files for filesort, transaction temporary space, analyze, binlog_stmt_cache etc. It does not include engine internal temporary files used for repair, alter table, index pre sorting etc. - All internal on disk temporary tables created as part of resolving a SELECT, multi-source update etc. Special cases: - When doing a commit, the last flush of the binlog_stmt_cache will not cause an error even if the temporary space limit is exceeded. This is to avoid giving errors on commit. This means that a user can temporary go over the limit with up to binlog_stmt_cache_size. Noteworthy issue: - One has to be careful when using small values for max_tmp_space_limit together with binary logging and with non transactional tables. If a the binary log entry for the query is bigger than binlog_stmt_cache_size and one hits the limit of max_tmp_space_limit when flushing the entry to disk, the query will abort and the binary log will not contain the last changes to the table. This will also stop the slave! This is also true for all Aria tables as Aria cannot do rollback (except in case of crashes)! One way to avoid it is to use @@binlog_format=statement for queries that updates a lot of rows. Implementation: - All writes to temporary files or internal temporary tables, that increases the file size, are routed through temp_file_size_cb_func() which updates and checks the temp space usage. - Most of the temporary file monitoring is done inside IO_CACHE. Temporary file monitoring is done inside the Aria engine. - MY_TRACK and MY_TRACK_WITH_LIMIT are new flags for ini_io_cache(). MY_TRACK means that we track the file usage. TRACK_WITH_LIMIT means that we track the file usage and we give an error if the limit is breached. This is used to not give an error on commit when binlog_stmp_cache is flushed. - global_tmp_space_used contains the total tmp space used so far. This is needed quickly check against max_total_tmp_space_usage. - Temporary space errors are using EE_LOCAL_TMP_SPACE_FULL and handler errors are using HA_ERR_LOCAL_TMP_SPACE_FULL. This is needed until we move general errors to it's own error space so that they cannot conflict with system error numbers. - Return value of my_chsize() and mysql_file_chsize() has changed so that -1 is returned in the case my_chsize() could not decrease the file size (very unlikely and will not happen on modern systems). All calls to _chsize() are updated to check for > 0 as the error condition. - At the destruction of THD we check that THD::tmp_file_space == 0 - At server end we check that global_tmp_space_used == 0 - As a precaution against errors in the tmp_space_used code, one can set max_tmp_space_usage and max_total_tmp_space_usage to 0 to disable the tmp space quota errors. - truncate_io_cache() function added. - Aria tables using static or dynamic row length are registered in 8K increments to avoid some calls to update_tmp_file_size(). Other things: - Ensure that all handler errors are registered.

BUG#38350: Many tests don't clean up after themselves on exit. Problem: Many test cases don't clean up after themselves (fail to drop tables or fail to reset variables). This implies that: (1) check-testcase in the new mtr that currently lives in 5.1-rpl failed. (2) it may cause unexpected results in subsequent tests. Fix: make all tests clean up. Also: cleaned away unnecessary output in rpl_packet.result Also: fixed bug where rpl_log called RESET MASTER with a running slave. This is not supposed to work. Also: removed unnecessary code from rpl_stm_EE_err2 and made it verify that an error occurred. Also: removed unnecessary code from rpl_ndb_ctype_ucs2_def. mysql-test/extra/rpl_tests/rpl_loaddata.test: Made test clean up after itself. mysql-test/extra/rpl_tests/rpl_stm_EE_err2.test: Made test clean up after itself. Also removed unnecessary save_master_pos. Also made test verify that an error occurred. mysql-test/extra/rpl_tests/rpl_truncate_helper.test: Made test clean up after itself. mysql-test/include/query_cache.inc: Made test clean up after itself. mysql-test/suite/binlog/t/binlog_auto_increment_bug33029.test: Made test clean up after itself. mysql-test/suite/rpl/t/rpl_alter_db.test: Made test clean up after itself. Easiest to refactor the test a little, to use an auxiliary database instead of mysql: Then we don't need to read the collation at the start of the test and reset it at the end of the test. We can just drop the database. mysql-test/suite/rpl/t/rpl_drop_db.test: Made test clean up after itself. mysql-test/suite/rpl/t/rpl_drop_view.test: Made test clean up after itself. mysql-test/suite/rpl/t/rpl_events.test: Made test clean up after itself. mysql-test/suite/rpl/t/rpl_idempotency.test: Made test clean up after itself. mysql-test/suite/rpl/t/rpl_ignore_table.test: Made test clean up after itself. The existing cleanup code didn't work, because the --replicate-* options prevented the "drop table" from being replicated. Moved "drop table t4" to a statement of its own. mysql-test/suite/rpl/t/rpl_packet.test: Made test clean up after itself. Also replaced SHOW SLAVE STATUS by query_get_value(SHOW SLAVE STATUS...), since only one column of the result was interesting. mysql-test/suite/rpl/t/rpl_row_max_relay_size.test: Made test clean up after itself. Instead of setting binlog format at the beginning of the test, we just do 'source include/have_binlog_format_row.inc' like all other tests. mysql-test/suite/rpl_ndb/t/rpl_ndb_2other.test: Made test clean up after itself. mysql-test/suite/rpl_ndb/t/rpl_ndb_ctype_ucs2_def.test: Made test clean up after itself.

MDEV-9101 Limit size of created disk temporary files and tables Two new variables added: - max_tmp_space_usage : Limits the the temporary space allowance per user - max_total_tmp_space_usage: Limits the temporary space allowance for all users. New status variables: tmp_space_used & max_tmp_space_used New field in information_schema.process_list: TMP_SPACE_USED The temporary space is counted for: - All SQL level temporary files. This includes files for filesort, transaction temporary space, analyze, binlog_stmt_cache etc. It does not include engine internal temporary files used for repair, alter table, index pre sorting etc. - All internal on disk temporary tables created as part of resolving a SELECT, multi-source update etc. Special cases: - When doing a commit, the last flush of the binlog_stmt_cache will not cause an error even if the temporary space limit is exceeded. This is to avoid giving errors on commit. This means that a user can temporary go over the limit with up to binlog_stmt_cache_size. Noteworthy issue: - One has to be careful when using small values for max_tmp_space_limit together with binary logging and with non transactional tables. If a the binary log entry for the query is bigger than binlog_stmt_cache_size and one hits the limit of max_tmp_space_limit when flushing the entry to disk, the query will abort and the binary log will not contain the last changes to the table. This will also stop the slave! This is also true for all Aria tables as Aria cannot do rollback (except in case of crashes)! One way to avoid it is to use @@binlog_format=statement for queries that updates a lot of rows. Implementation: - All writes to temporary files or internal temporary tables, that increases the file size, are routed through temp_file_size_cb_func() which updates and checks the temp space usage. - Most of the temporary file monitoring is done inside IO_CACHE. Temporary file monitoring is done inside the Aria engine. - MY_TRACK and MY_TRACK_WITH_LIMIT are new flags for ini_io_cache(). MY_TRACK means that we track the file usage. TRACK_WITH_LIMIT means that we track the file usage and we give an error if the limit is breached. This is used to not give an error on commit when binlog_stmp_cache is flushed. - global_tmp_space_used contains the total tmp space used so far. This is needed quickly check against max_total_tmp_space_usage. - Temporary space errors are using EE_LOCAL_TMP_SPACE_FULL and handler errors are using HA_ERR_LOCAL_TMP_SPACE_FULL. This is needed until we move general errors to it's own error space so that they cannot conflict with system error numbers. - Return value of my_chsize() and mysql_file_chsize() has changed so that -1 is returned in the case my_chsize() could not decrease the file size (very unlikely and will not happen on modern systems). All calls to _chsize() are updated to check for > 0 as the error condition. - At the destruction of THD we check that THD::tmp_file_space == 0 - At server end we check that global_tmp_space_used == 0 - As a precaution against errors in the tmp_space_used code, one can set max_tmp_space_usage and max_total_tmp_space_usage to 0 to disable the tmp space quota errors. - truncate_io_cache() function added. - Aria tables using static or dynamic row length are registered in 8K increments to avoid some calls to update_tmp_file_size(). Other things: - Ensure that all handler errors are registered. Before, some engine errors could be printed as "Unknown error". - Fixed bug in filesort() that causes a assert if there was an error when writing to the temporay file. - Fixed that compute_window_func() now takes into account write errors. - In case of parallel replication, rpl_group_info::cleanup_context() could call trans_rollback() with thd->error set, which would cause an assert. Fixed by resetting the error before calling trans_rollback(). - Fixed bug in subselect3.inc which caused following test to use heap tables with low value for max_heap_table_size - Fixed bug in sql_expression_cache where it did not overflow heap table to Aria table. - Added Max_tmp_disk_space_used to slow query log. - Fixed some bugs in log_slow_innodb.test
