In Galera 4, the implementation would seem to require changes to the streaming replication. In the tests archive.rnd_pos main.profiling, disable_ps_protocol for SHOW STATUS and SHOW PROFILE commands until MDEV-18974 has been fixed.

Affected sql_analyse.h, mi_write.c and ma_write.cc, mf_iocache-t.cc, mysqlbinlog.cc, encryption.cc, etc 2. memcpy/memset of nontrivial structures. Fixed as: * the warning disabled for InnoDB * TABLE, TABLE_SHARE, and TABLE_LIST got a new method reset() which does the bzero(), which is safe for these classes, but any other bzero() will still cause a warning * Table_scope_and_contents_source_st uses `TABLE_LIST *` (trivial) instead of `SQL_I_List<TABLE_LIST>` (not trivial) so it's safe to bzero now. * added casts in debug_sync.cc and sql_select.cc (for JOIN) * move assignment method for MDL_request instead of memcpy() * PARTIAL_INDEX_INTERSECT_INFO::init() instead of bzero() * remove constructor from READ_RECORD() to make it trivial * replace some memcpy() with c++ copy assignments
* | | | Added new MDL_BACKUP locks for all backup stagesMonty2018-12-091-7/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Part of MDEV-5336 Implement LOCK FOR BACKUP - Added new locks to MDL_BACKUP for all stages of backup locks and a new MDL lock needed for backup stages. - Renamed MDL_BACKUP_STMT to MDL_BACKUP_DDL - flush_tables() takes a new parameter that decides what should be flushed. - InnoDB, Aria (transactional tables with checksums), Blackhole, Federated and Federatedx tables are marked to be safe for online backup. We are using MDL_BACKUP_TRANS_DML instead of MDL_BACKUP_DML locks for these which allows any DML's to proceed for these tables during the whole backup process until BACKUP STAGE COMMIT which will block the final commit.
* | | | Acquire global read lock (MDL_BACKUP_STMT) after share is acquiredSergey Vojtovich2018-12-091-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Part of MDEV-5336 Implement LOCK FOR BACKUP FLUSH TABLE table_names have changed slighty as we are now opening tables before taking the MDL lock. The difference is that FLUSH TABLE table_name will now be blocked by a table that is waiting for FTWRL. There should not be any new deadlocks as part of this change. The end result is still better in most cases as FTWRL is now only waiting for write statements to end, not for read only statements and it's not flushing tables in use from the table cache. Share will be needed to be able to determine if table supports online backup. Appropriate metadata lock type in BACKUP namespace will be acquired basing on this information. Also made pending global read lock request to be preferred victim of MDL deadlock detector. This allows us to hide some non-fatal deadlocks and make FTWRL less likely to break concurrent queries.

END; CREATE DEFINER user@host PACKAGE BODY pkg ... END; - CREATE PACKAGE [BODY] now supports SQL SECURITY and COMMENT clauses, e.g.: CREATE PACKAGE p1 SQL SECURITY INVOKER COMMENT "comment" AS ... END; - Package routines are now created from the package CREATE PACKAGE BODY statement and don't produce individual records in mysql.proc. - CREATE PACKAGE BODY now supports package-wide variables. Package variables can be read and set inside package routines. Package variables are stored in a separate sp_rcontext, which is cached in THD on the first packate routine call. - CREATE PACKAGE BODY now supports the initialization section. - All public routines (i.e. declared in CREATE PACKAGE) must have implementations in CREATE PACKAGE BODY - Only public package routines are available outside of the package - {CREATE|DROP} PACKAGE [BODY] now respects CREATE ROUTINE and ALTER ROUTINE privileges - "GRANT EXECUTE ON PACKAGE BODY pkg" is now supported - SHOW CREATE PACKAGE [BODY] is now supported - SHOW PACKAGE [BODY] STATUS is now supported - CREATE and DROP for PACKAGE [BODY] now works for non-current databases - mysqldump now supports packages - "SHOW {PROCEDURE|FUNCTION) CODE pkg.routine" now works for package routines - "SHOW PACKAGE BODY CODE pkg" now works (the package initialization section) - A new package body level MDL was added - Recursive calls for package procedures are now possible - Routine forward declarations in CREATE PACKATE BODY are now supported. - Package body variables now work as SP OUT parameters - Package body variables now work as SELECT INTO targets - Package body variables now support ROW, %ROWTYPE, %TYPE

* | MDEV-11227 - mysqlimport -l doesn't issue UNLOCK TABLESSergey Vojtovich2016-12-211-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-8791 - AIX: Unresolved Symbols during linkingSergey Vojtovich2016-10-311-9/+0
|/ | | | | | | | | | | | | | | | | | | | | | | | | Clean-up nolock.h: it doesn't serve any purpose anymore. Appropriate code moved to x86-gcc.h and my_atomic.h. If gcc sync bultins were detected, we want to make use of them independently of __GNUC__ definition. E.g. XLC simulates those, but doesn't define __GNUC__. HS/Spider: According to AIX manual alloca() returns char*, which cannot be casted to any type with static_cast. Use explicit cast instead. MDL: Removed namemangling pragma, which didn't let MariaDB build with XLC. WSREP: _int64 seem to be conflicting name with XLC, replaced with _integer64. CONNECT: RTLD_NOLOAD is GNU extention. Removed rather meaningless check if library is loaded. Multiple dlopen()'s of the same library are permitted, and it never gets closed anyway. Except for error, which was a bug: it may close library, which can still be referenced by other subsystems. InnoDB: __ppc_get_timebase() is GNU extention. Only use it when __GLIBC__ is defined. Based on contribution by flynn1973.

Reduced number of memory accesses done by my_hash_sort_bin(). Details: - let MDL subsystem use pre-calculated hash value for hash inserts and deletes - let table cache use pre-calculated MDL hash value - MDL namespace is excluded from hash value calculation, so that hash value can be used by table cache as is - hash value for MDL is calculated as resulting hash value + MDL namespace - extended hash implementation to accept user defined hash function
