                  main.mysqlslap fail on PPC64
      
      There seem to be a bug on Power8 which doesn't guarantee
      a signal to be delivered to waiting thread if broadcast
      is called outside of mutex.
      
      For now workaround it by calling broadcast while mutex is
      still held.

      MDEV-6483 - Deadlock around rw_lock_debug_mutex on PPC64 · 6192f0bf
      Sergey Vojtovich authored
      This problem affects only debug builds on PPC64.
      
      There are at least two race conditions around
      rw_lock_debug_mutex_enter and rw_lock_debug_mutex_exit:
      
      - rw_lock_debug_waiters was loaded/stored without setting
        appropriate locks/memory barriers.
      - there is a gap between calls to os_event_reset() and
        os_event_wait() and in such case we're supposed to pass
        return value of the former to the latter.
      
      Fixed by replacing self-cooked spinlocks with system mutexes.
      These days system mutexes offer much better performance. OTOH
      performance is not that critical for debug builds.

      Fixed problem with very slow shutdown when using 100,000 MyISAM tables with delay_key_write · f0f2072d
      Michael Widenius authored
      Reason for the problem was that the hash of changed files in the key cache was too small (was 128). Fixed by making the hash size larger and changeable.
      
      - Introduced key-cache-file-hash-size (default 512) for MyISAM and aria_pagecache_file_hash_size (default 512) for Aria.
      - Added new status variable "Feature_delay_key_write" which counts number of tables opened that are using delay_key_write

      Fixed assert in perfschema/pfs.cc::start_idle_wait_v1 when using performance... · ff205b25
      Michael Widenius authored
      Fixed assert in perfschema/pfs.cc::start_idle_wait_v1 when using performance schema and big packets in debug version.
      
      The bug was that my_real_read() called net_before_header_psi() multiple times for long packets.
      Fixed by adding a flag when we are reading a header.
      Did also some cleanups to interface of my_net_read() to avoid unnecessary calls if performance schema is not used.
      
      - Added my_net_read_packet() as a replacement for my_net_read(). my_net_read() is still in the client library for old clients.
      - Removed THD->m_server_idle (not needed anymore as this is now given as argument to my_net_read_packet()
      - Added my_net_read_packet(), which is a new version of my_net_read() with a new parameter if we are doing a read for a new command from the server.
      - Added tests for compressed protocol and big packets
      
      
      
      
      
      include/mysql.h.pp:
        Added my_net_read_packet() as a replacement for my_net_read()
      include/mysql_com.h:
        Added my_net_read_packet() as a replacement for my_net_read()
      mysql-test/r/mysql_client_test_comp.result:
        New test
      mysql-test/t/mysql_client_test-master.opt:
        Added max_allowed_packet to be able to test big packets and packet size overflows.
      mysql-test/t/mysql_client_test_comp-master.opt:
        New test
      mysql-test/t/mysql_client_test_nonblock-master.opt:
        Added max_allowed_packet to be able to test big packets and packet size overflows.
      sql-common/client.c:
        Use my_net_read_packet()
      sql/mf_iocache.cc:
        Use my_net_read_packet()
      sql/mysqld.cc:
        Removed THD->m_server_idle (not needed anymore as this is now given as argument to my_net_read_packet()
      sql/net_serv.cc:
        Added argument to my_real_read() to indicte if we are reading the first block of the next statement and should call performance schema.
        Added 'compatibilty function' my_net_read().
        Added my_net_read_packet(), which is a new version of my_net_read() with a new parameter if we are doing a read for a new command from the server.
      sql/sql_class.cc:
        Removed m_server_idle (not needed anymore)
      sql/sql_class.h:
        Removed m_server_idle (not needed anymore)

        Removed m_server_idle (not needed anymore)

      MDEV-6459 - max_relay_log_size and sql_slave_skip_counter · 54538b48
      Sergey Vojtovich authored
                  misbehave on PPC64
      
      There was a mix of ulong and uint casts/variables which caused
      incorrect value to be passed to/retrieved from max_relay_log_size
      and sql_slave_skip_counter.
      
      This mix failed to work on big-endian PPC64 where sizeof(int)= 4,
      sizeof(long)= 8. E.g. session_var(thd, uint)= 1 will in fact store
      0x100000000.

      MDEV-6450 - MariaDB crash on Power8 when built with advance tool · c0ebb3f3
      Sergey Vojtovich authored
                  chain
      
      InnoDB mutex_exit() function calls __sync_test_and_set() to release
      the lock. According to manual this function is supposed to create
      "acquire" memory barrier whereas in fact we need "release" memory
      barrier at mutex_exit().
      
      The problem isn't repeatable with gcc because it creates
      "acquire-release" memory barrier for __sync_test_and_set().
      ATC creates just "acquire" barrier.
      
      Fixed by creating proper barrier at mutex_exit() by using
      __sync_lock_release() instead of __sync_test_and_set().

      MDEV-5262, MDEV-5914, MDEV-5941, MDEV-6020: Deadlocks during parallel replication causing replication to fail.
      
      Merge the patches into MariaDB 10.0 main.
      
      With this patch, parallel replication will now automatically retry a
      transaction that fails due to deadlock or other temporary error, same as
      single-threaded replication.
      
      We catch deadlocks with InnoDB transactions due to enforced commit order. If
      T1 must commit before T2 in parallel replication and T1 ends up waiting for T2
      inside InnoDB, we kill T2 and retry it later to resolve the deadlock
      automatically.
