      MDEV-21689 Add Sql_cmd for GRANT/REVOKE statements · 77c63823
      Alexander Barkov authored
      Rewriting GRANT/REVOKE grammar to use more bison stack and use Sql_cmd_ style
      
      1. Removing a few members from LEX:
         - uint grant, grant_to_col, which_columns
         - List<LEX_COLUMN> columns
         - bool all_privileges
      2. Adding classes Grand_object_name, Lex_grant_object_name
      3. Adding classes Grand_privilege, Lex_grand_privilege
      4. Adding struct Lex_column_list_privilege_st, class Lex_column_list_privilege
      5. Rewriting the GRANT/REVOKE grammar to use new classes and pass them through
         bison stack (rather than directly access LEX members)
      6. Adding classes Sql_cmd_grant* and Sql_cmd_revoke*,
         changing GRANT/REVOKE to use LEX::m_sql_cmd.
      7. Adding the "sp_handler" grammar rule and removing some duplicate grammar
         for GRANT/REVOKE for different kinds of SP objects.
      8. Adding a new rule comma_separated_ident_list, reusing it in:
         - with_column_list
         - colum_list_privilege

      MDEV-21248: Prevent optimizing out buf argument in check_stack_overrun. · 35c27785
      Martin Liska authored
      When using LTO, one can see optimization of stack variables that
      are passed to check_stack_overrun as argument buf. That prevents
      proper stack overrun detection.

      MDEV-21674 purge_sys.stop() fails to wait for purge workers to complete · 8b97eba3
      Marko Mäkelä authored
      Since commit 5e62b6a5 (MDEV-16264),
      purge_sys_t::stop() no longer waited for all purge activity to stop.
      
      This caused problems on FLUSH TABLES...FOR EXPORT because of
      purge running concurrently with the buffer pool flush.
      The assertion at the end of buf_flush_dirty_pages() could fail.
      
      The, implemented by Vladislav Vaintroub, aims to eliminate race
      conditions when stopping or resuming purge:
      
      waitable_task::disable(): Wait for the task to complete, then replace
      the task callback function with noop.
      
      waitable_task::enable(): Restore the original task callback function
      after disable().
      
      purge_sys_t::stop(): Invoke purge_coordinator_task.disable().
      
      purge_sys_t::resume(): Invoke purge_coordinator_task.enable().
      
      purge_sys_t::running(): Add const qualifier, and clarify the comment.
      The purge coordinator task will remain active as long as any purge
      worker task is active.
      
      purge_worker_callback(): Assert purge_sys.running().
      
      srv_purge_wakeup(): Merge with the only caller purge_sys_t::resume().
      
      purge_coordinator_task: Use static linkage.

      MDEV-21351: Free processed recv_sys_t::blocks · 6d214415
      Marko Mäkelä authored
      Release memory as soon as redo log records are processed.
      
      Because the memory allocation and deallocation of parsed redo log
      records must be protected by recv_sys.mutex, it is better to avoid
      using a std::atomic field for bookkeeping.
      
      buf_page_t::access_time: Keep track of the recv_sys.pages record
      allocations. The most significant 16 bits will count allocated
      blocks (which were previously counted by buf_page_t::buf_fix_count
      in the debug version), and the least significant 16 bits indicate
      the number of allocated bytes in the block (which was previously
      managed in buf_block_t::modify_clock), which must be a positive
      number, up to innodb_page_size. The byte offset 65536 is represented
      as the value 0.
      
      recv_recover_page(): Let the caller erase the log.
      
      recv_validate_tablespace(): Acquire recv_sys_t::mutex.

      Fix:
      ===

      List of commands:
      
      On Master:
      =========
      SHOW REPLICA HOSTS <--> SHOW SLAVE HOSTS
      Privilege "SLAVE"  <--> "REPLICA"
      
      On Slave:
      =========
      START SLAVE       <--> START REPLICA
      START ALL SLAVES  <--> START ALL REPLICAS
      START SLAVE UNTIL <--> START REPLICA UNTIL
      STOP SLAVE        <--> STOP REPLICA
      STOP ALL SLAVES   <--> STOP ALL REPLICAS

      MDEV-20001 Potential dangerous regression: INSERT INTO >=100 rows fail for myisam table with HASH indexes
      
      Problem:-
      
      So the issue is when we do bulk insert with rows
      > MI_MIN_ROWS_TO_DISABLE_INDEXES(100) , We try to disable the indexes to
      speedup insert. But current logic also disables the long unique indexes.
      
      Solution:- In ha_myisam::start_bulk_insert if we find long hash index
      (HA_KEY_ALG_LONG_HASH) we will not disable the index.
      
      This commit also refactors the mi_disable_indexes_for_rebuild function,
      Since this is function is called at only one place, it is inlined into
      start_bulk_insert
      
      mi_clear_key_active is added into myisamdef.h because now it is also used
      in ha_myisam.cc file.
      
      (Same is done for Aria Storage engine)

      MDEV-17844 recs_off_validate() fails in page_zip_write_trx_id_and_roll_ptr() · d87b725e
      Marko Mäkelä authored
      In commit 0e5a4ac2 (MDEV-15562)
      we introduced was a bogus debug check failure that does not affect
      the correctness of the release build.
      
      With a fixed-length PRIMARY KEY, we do not have to recompute
      the rec_get_offsets() after restarting the mini-transaction,
      because the offsets of DB_TRX_ID,DB_ROLL_PTR are not going
      to change.
      
      row_undo_mod_clust(): Invoke rec_offs_make_valid() to keep the
      debug check in page_zip_write_trx_id_and_roll_ptr() happy.
      
      The scenario to reproduce this bug should be rather unlikely:
      In the time frame when row_undo_mod_clust() has committed its
      first mini-transaction and has not yet started the next one,
      another mini-transaction must do something that causes the page
      to be reorganized, split or merged.

      Galera GTID support · 41bc7368
      mkaruza authored
      Support for galera GTID consistency thru cluster. All nodes in cluster
      should have same GTID for replicated events which are originating from cluster.
      Cluster originating commands need to contain sequential WSREP GTID seqno
      Ignore manual setting of gtid_seq_no=X.
      
      In master-slave scenario where master is non galera node replicated GTID is
      replicated and is preserved in all nodes.
      
      To have this - domain_id, server_id and seqnos should be same on all nodes.
      Node which bootstraps the cluster, to achieve this, sends domain_id and
      server_id to other nodes and this combination is used to write GTID for events
      that are replicated inside cluster.
      
      Cluster nodes that are executing non replicated events are going to have different
      GTID than replicated ones, difference will be visible in domain part of gtid.
      
      With wsrep_gtid_domain_id you can set domain_id for WSREP cluster.
      
      Functions WSREP_LAST_WRITTEN_GTID, WSREP_LAST_SEEN_GTID and
      WSREP_SYNC_WAIT_UPTO_GTID now works with "native" GTID format.
      
      Fixed galera tests to reflect this chances.
      
      Add variable to manually update WSREP GTID seqno in cluster
      
      Add variable to manipulate and change WSREP GTID seqno. Next command
      originating from cluster and on same thread will have set seqno and
      cluster should change their internal counter to it's value.
      Behavior is same as using @@gtid_seq_no for non WSREP transaction.
