      Don't use instal_jar() from Use_Java.cmake -
      at least in CentOS 7 (cmake 2.8.12.2) it doesn't yet support

      MDEV-12660 inconsistent mysql_stmt_close · a8773ef3
      Sergei Golubchik authored
      remove dead code: this "return rc" could've never happened,
      because reset_stmt_handle can only possibly fail if RESET_SERVER
      flag is used.
      
      But this "return rc" was confusing, it was under DBUG_ENTER (while
      not being DBUG_RETURN) and it was skipping required stmt cleanup
      at the end of the function.

      MDEV-12761 Error return from external_lock make the server crash · f9264280
      Sergei Golubchik authored
      bunch of bugs when external_lock() fails on unlock:
      * mi_lock_database() used mi_mark_crashed() under share->intern_lock,
        but mi_mark_crashed() itself locks this mutex.
      * handler::close() required table to be unlocked, but failed
        external_lock didn't count as unlock
      * mysql_unlock_tables() ignored all unlock errors, but they still set
        the error status in stmt_da.

      MDEV-12188 information schema - errors populating fail to free memory, unlock mutexes · 217b8115
      Marko Mäkelä authored
      Given the OK macro used in innodb does a DBUG_RETURN(1) on expression failure
      the innodb implementation has a number of errors in i_s.cc.
      
      We introduce a new macro BREAK_IF that replaces some use of the OK macro.
      Also, do some other cleanup detailed below.
      
      When invoking Field::store() on integers, always pass the parameter
      is_unsigned=true to avoid an unnecessary conversion to double.
      
      i_s_fts_deleted_generic_fill(), i_s_fts_config_fill():
      Use the BREAK_IF macro instead of OK.
      
      i_s_fts_index_cache_fill_one_index(), i_s_fts_index_table_fill_one_index():
      Add a parameter for conv_string, and let the caller allocate that buffer.
      
      i_s_fts_index_cache_fill(): Check the return status of
      i_s_fts_index_cache_fill_one_index().
      
      i_s_fts_index_table_fill(): Check the return status of
      i_s_fts_index_table_fill_one_index().
      
      i_s_fts_index_table_fill_one_fetch(): Always let the caller invoke
      i_s_fts_index_table_free_one_fetch().
      
      i_s_innodb_buffer_page_fill(), i_s_innodb_buf_page_lru_fill():
      Do release dict_sys->mutex if filling the buffers fails.
      
      i_s_innodb_buf_page_lru_fill(): Also display the value
      INFORMATION_SCHEMA.INNODB_BUFFER_PAGE.PAGE_IO_FIX='IO_PIN'
      when a block is in that state. Remove the unnecessary variable 'heap'.

      Fix the Solaris compilation after MDEV-12674 · 8417252b
      Marko Mäkelä authored
      simple_counter::add(): Add a type cast to the os_atomic_increment_ulint()
      call, because GCC would check the type compatibility even when the code
      branch is not being instantiated (atomic=false). On Solaris,
      os_atomic_increment_ulint() actually needs a compatible parameter type,
      and an error would be emitted due to an incompatible 64-bit type,
      for srv_stats.n_lock_wait_time.add(diff_time).

      MDEV-12674 Innodb_row_lock_current_waits has overflow · ff166093
      Marko Mäkelä authored
      There is a race condition related to the variable
      srv_stats.n_lock_wait_current_count, which is only
      incremented and decremented by the function lock_wait_suspend_thread(),
      
      The incrementing is protected by lock_sys->wait_mutex, but the
      decrementing does not appear to be protected by anything.
      This mismatch could allow the counter to be corrupted when a
      transactional InnoDB table or record lock wait is terminating
      roughly at the same time with the start of a wait on a
      (possibly different) lock.
      
      ib_counter_t: Remove some unused methods. Prevent instantiation for N=1.
      Add an inc() method that takes a slot index as a parameter.
      
      single_indexer_t: Remove.
      
      simple_counter<typename Type, bool atomic=false>: A new counter wrapper.
      Optionally use atomic memory operations for modifying the counter.
      Aligned to the cache line size.
      
      lsn_ctr_1_t, ulint_ctr_1_t, int64_ctr_1_t: Define as simple_counter<Type>.
      These counters are either only incremented (and we do not care about
      losing some increment operations), or the increment/decrement operations
      are protected by some mutex.
      
      srv_stats_t::os_log_pending_writes: Document that the number is protected
      by log_sys->mutex.
      
      srv_stats_t::n_lock_wait_current_count: Use simple_counter<ulint, true>,
      that is, atomic inc() and dec() operations.
      
      lock_wait_suspend_thread(): Release the mutexes before incrementing
      the counters. Avoid acquiring the lock mutex if the lock wait has
      already been resolved. Atomically increment and decrement
      srv_stats.n_lock_wait_current_count.
      
      row_insert_for_mysql(), row_update_for_mysql(),
      row_update_cascade_for_mysql(): Use the inc() method with the trx->id
      as the slot index. This is a non-functional change, just using
      inc() instead of add(1).
      
      buf_LRU_get_free_block(): Replace the method add(index, n) with inc().
      There is no slot index in the simple_counter.

      MDEV-10104 Table lock race condition with replication · fc25437a
      Monty authored
      Problem was two race condtion in Aria page cache:
      - find_block() didn't inform free_block() that it had released requests
      - free_block() didn't handle pinned blocks, which could happen if
        free_block() was called as part of flush. This is fixed by not freeing
        blocks that are pinned.  This is safe as when maria_close() is called
        when last thread is using a table, there can be no pinned blocks. For
        other flush calls it's safe to ignore pinned blocks.

      MDEV-12635 innodb.log_file_size fails when run with Valgrind · bc5c1d99
      Marko Mäkelä authored
      In MariaDB Server before 10.2, InnoDB will not be shut down properly
      if startup fails. So, Valgrind failures are to be expected.
      Disable the test under Valgrind. In 10.2, it should pass with Valgrind.

      Fixed the bug mdev-12673. · 15f9931f
      Igor Babaev authored
      This patch corrects the fix for the bug mdev-10693.
      It is critical for the function get_best_combination() not to call
      create_ref_for_key() for constant tables.
      This bug could manifest itself only in multi-table subqueries where
      one of the tables is accessed by a constant primary key.

      Fixed the bug mdev-10693. · 2e7ba70a
      Igor Babaev authored
      The code that chooses between materialization of a non-correlated
      IN subquery and its transformation into an EXISTS correlated
      subquery assumes that the execution plan for the outer select
      has been already built. However it was not always so if subqueries
      occurred in the expressions used for ref access to tables of
      the outer select. A call of the function create_ref_for_key() in
      get_best_combination() could trigger a premature execution of
      the above mentioned code when the execution plan structures for
      the outer select were not fully built. This could cause a crash
      of the server.
      
      The fix postpones the calls of create_ref_for_key() until the
      structures for the execution plan is fully built.

      Fixed bug mdev-10053. · 97fb1f26
      Igor Babaev authored
      The implementation of the walk method for the class Item_in_subselect
      was missing. As a result the method never traversed the left operand
      of any IN subquery predicate.
      
      Item_exists_subselect::exists2in_processor() that performs the
      Exist-To-In transformation calls the walk method to collect info
      on outer references. As the walk method did not traverse the
      left operands of the IN subqueries the outer references there
      were not taken into account and some subqueries that were actually
      correlated were marked as uncorrelated. It could lead to an
      attempt of the materialization of such a subquery.
      
      Also added a cleanup for some test cases merged from 5.5.

      MDEV-12488 Remove type mismatch in InnoDB printf-like calls · 87b6df31
      Marko Mäkelä authored
      This is a reduced version of an originally much larger patch.
      We will keep the definition of the ulint, lint data types unchanged,
      and we will not be replacing fprintf() calls with ib_logf().
      
      On Windows, use the standard format strings instead of nonstandard
      extensions.
      
      This patch fixes some errors in format strings.
      Most notably, an IMPORT TABLESPACE error message in InnoDB was
      displaying the number of columns instead of the mismatching flags.
