Nikita Malyavin	c436b6a2bc	MDEV-33450 Assertion fails in main.alter_table_online_debug Assertion "from->s->online_alter_binlog == NULL" fails in copy_data_between_tables, signalizing that a table share is being reused (in another alter) after a lock upgrade to EXCLUSIVE fails. Commit `3059f27` relaxed the lock to be upgraded to MDL_SHARED_NO_WRITE, leaving it to happen later by a common path wait_while_table_is_used() call. However the error handling there is not enough for online alter case, where we require (for now) the table to be flushed, in order to clean up the memory properly. * Add another lock upgrade (to MDL_EXCLUSIVE) after the second replication stage in copy_data_between_tables. The error from this upgrade will be handled by the branch presented further in the function. MDEV-33450 Assertion fails in main.alter_table_online_debug `TABLE_SHARE` that is being online-altered has a shared `s->online_alter_binlog` member that all concurrent DMLs are writing to. Online alter thread deletes it under the MDL_EXCLUSIVE. If upgrading the lock to MDL_EXCLUSIVE fails, table as marked as `flushed` and it's freed automatically when its usage drops to zero. In commit `3059f27` the lock upgrade was relaxed to MDL_SHARED_NO_WRITE to allow concurrent SELECT threads during the final `online_alter_read_from_binlog()` pass. An attempt to upgrade the lock to MDL_EXCLUSIVE was still happening, but much later — after the code that marked the table `flushed`. That is, if the upgrade failed, the table was left with a stale `s->online_alter_binlog` triggering an assert in a future online alter. To fix this, upgrade the lock to MDL_EXCLUSIVE earlier, after the final `online_alter_read_from_binlog()`.	2 years ago

Vladislav Vaintroub	88f49da8e0	MDEV-34063 tpool - integer overflow in multiplication. When calculating next wakeup timepoint for the timer thread, with large thread_pool_stall_limit values, 32bit int overflow can happen. Fixed by making one operand 8 byte large. Also fixed the type of tick_interval to be unsigned, so it does not go negative for very thread_pool_stall_limit.	2 years ago

Brandon Nesterenko	e4afa61053	MDEV-7850: Extend GTID Binlog Events with Thread Id This patch augments Gtid_log_event with the user thread-id. In particular that compensates for the loss of this info in Rows_log_events. Gtid_log_event::thread_id gets visible in mysqlbinlog output like #231025 16:21:45 server id 1 end_log_pos 537 CRC32 0x1cf1d963 GTID 0-1-2 ddl thread_id=10 as a 32 bit unsigned integer. Note this is a 32-bit value, as the connection id can only be 32 bits (see MDEV-15089 for details). While the size of Gtid event has grown by 4 bytes replication from OLD <-> NEW is not affected by it. This patch also slightly changes the logic to convert Gtid events to Query events for older replicas which don't support Gtid. Instead of hard-coding the padding of the sys var section of the generated Query event, the length to pad is dynamically calculated based on the length of the Gtid event. This work was started by the late Sujatha Sivakumar. Brandon Nesterenko took it over, reviewed initial patches and extended the work. Also thanks to Andrei for his help in finalizing the fixes for MDEV-33924, which were squashed into this patch.

Kristian Nielsen	e365877bae	MDEV-33798: ROW base optimistic deadlock with concurrent writes on same table One case is conflicting transactions T1 and T2 with different domain id, in optimistic parallel replication in non-GTID mode. Then T2 will wait_for_prior_commit on T1; and if T1 got a row lock wait on T2 it would hang, as different domains caused the deadlock kill to be skipped in thd_rpl_deadlock_check(). More generally, if we have transactions T1 and T2 in one domain/master connection, and independent transactions U in another, then we can still deadlock like this: T1 row low wait on U U row lock wait on T2 T2 wait_for_prior_commit on T1 This commit enforces the deadlock kill in these cases. If the waited-for transaction is speculatively applied, then it will be deadlock killed in case of a conflict, even if the two transactions are in different domains or master connections.

mariadb-DebarunBanerjee	90b95c6149	MDEV-33543 Server hang caused by InnoDB change buffer Issue: When getting a page (buf_page_get_gen) with no latch option (RW_NO_LATCH), the caller is not expected to follow the B-tree latching order. However in buf_page_get_low we try to acquire shared page latch unconditionally to wait for a page that is being loaded by another thread concurrently. In general it could lead to latch order violation and deadlock. Currently it affects the change buffer insert path btr_latch_prev() which tries to load the previous page out of order with RW_NO_LATCH and two concurrent inserts into IBUF tree cause deadlock. This problem is introduced in 10.6 by following commit. commit `9436c778c3` (MDEV-27058) Fix: While trying to latch a page with RW_NO_LATCH, always use the "*lock_try" interface and retry operation on failure after unfixing the page.	2 years ago

mariadb-DebarunBanerjee	52f6df99ed	MDEV-33669 mariabackup --backup hangs This is a server hang and not an issue with backup. While concurrent DDLs in server gets in hanged state, mariabackup waits for DDLs to finish trying to acquire MDL_BACKUP_BLOCK_DDL. The server hang is serious in nature and caused by thread pool state being incorrectly set to thread creation pending state while no creation is actually pending. Once a thread pool reaches such state no new thread gets created in the pool. While it could possibly affect all thread pools in server, the innodb thread pool is the victim in current bug where IO job gets blocked when the pool is stuck with much less number of threads than intended. Available workers are blocked in purge waiting for page lock to be released by IO write (SX lock) causing a complete deadlock. The issue is caused by the state variable m_thread_creation_pending introduced by MDEV-31095: `9e62ab7aaf`. We check and set the variable early while attempting to create a new thread in pool but fail to reset it if we exit the flow for other reasons like maximum threads reached or get into thread creation throttling path. Fix: The simple fix is to make sure that the state is reset back in case we don't actually attempt to create the thread.	2 years ago

Alexander Barkov	001f93df2b	MDEV-12668 SRID is not preserved in UNION, VIEW, MIN, MAX Fixing the problem that an operation involving a mix of two or more GEOMETRY operands did not preserve their SRIDs. Now SRIDs are preserved by hybrid functions, subqueries, TVCs, UNIONs, VIEWs. Incompatible change: An attempt to mix two different SRIDs now raises an error. Details: - Adding a new class Type_extra_attributes. It's a generic container which can store very specific data type attributes. For now it can store one uint32 and one const pointer attribute (for GEOMETRY's SRID and for ENUM/SET TYPELIB respectively). In the future it can grow as needed. Type_extra_attributes will also be reused soon to store "const Type_zone" pointers for the TIMESTAMP's "WITH TIME ZONE 'tz'" attribute (a timestamp data type with a fixed time zone independent from @@time_zone). The time zone attribute will be stored in exactly the same way like a TYPELIB pointer is stored by ENUM/SET. - Removing Column_definition_attributes members "interval" and "srid". Deriving Column_definition_attributes from the generic attribute container Type_extra_attributes instead. - Adding a new class Type_typelib_attributes, to store the TYPELIB of the ENUM and SET data types. Deriving Field_enum from it. Removing the member Field_enum::typelib. - Adding a new class Type_geom_attributes, to store the GEOMETRY related attributes. Deriving Field_geom from it. Removing the member Field_geom::srid. - Removing virtual methods: Field::get_typelib() Type_all_attributes::get_typelib() and Type_all_attributes::set_typelib() They were very specific to TYPELIB. Adding more generic virtual methods instead: Field::type_extra_attributes() - to get extra attributes * Type_all_attributes::type_extra_attributes() - to get extra attributes * Type_all_attributes::type_extra_attributes_addr() - to set extra attributes - Removing Item_type_holder::enum_set_typelib. Deriving Item_type_holder from the generic attribute container Type_extra_attributes instead. This makes it possible for UNION to preserve SRID (in addition to preserving TYPELIB). - Deriving Item_hybrid_func from Type_extra_attributes. This makes it possible for hybrid functions (e.g. CASE, COALESCE, LEAST, GREATEST etc) to preserve SRID. - Deriving Item_singlerow_subselect from Type_extra_attributes and overriding methods: * Item_cache::type_extra_attributes() * subselect_single_select_engine::fix_length_and_dec() * Item_singlerow_subselect::type_extra_attributes() * Item_singlerow_subselect::type_extra_attributes_addr() This is needed to preserve SRID in subqueries and TVCs - Cleanup: fixing the data type of members * Binlog_type_info::m_enum_typelib * Binlog_type_info::m_set_typelib from "TYPELIB " to "const TYPELIB "	2 years ago
