      Fix for bug #25966 "2MB per second endless memory consumption after LOCK · db1d2f64
      unknown authored
      TABLE ... WRITE".
      
      CPU hogging occured when connection which had to wait for table lock was
      serviced by thread which previously serviced connection that was killed
      (note that connections can reuse threads if thread cache is enabled).
      One possible scenario which exposed this problem was when thread which
      provided binlog dump to replication slave was implicitly/automatically
      killed when the same slave reconnected and started pulling data through
      different thread/connection.
      In 5.* versions memory hogging was added to CPU hogging. Moreover in
      those versions the problem also occured when one killed particular query
      in connection (using KILL QUERY) and later this connection had to wait for
      some table lock.
      
      This problem was caused by the fact that thread-specific mysys_var::abort
      variable, which indicates that waiting operations on mysys layer should
      be aborted (this includes waiting for table locks), was set by kill
      operation but was never reset back. So this value was "inherited" by the
      following statements or even other connections (which reused the same
      physical thread). Such discrepancy between this variable and THD::killed
      flag broke logic on SQL-layer and caused CPU and memory hogging.
      
      This patch tries to fix this problem by properly resetting this member.
      
      There is no test-case associated with this patch since it is hard to test
      for memory/CPU hogging conditions in our test-suite.
      
      
      sql/mysqld.cc:
        We should not forget to reset THD::mysys_var::abort after kill operation
        if we are going to use thread to which this operation was applied for
        handling of other connections.

      Bug#24878 mysql server doesn't log incident time in "mysqld got signal 11" error messages · 87eee8fc

       - Add printout of current time when mysqld is killed by an

      sql/mysqld.cc:
        Add printout of current time before the "mysqld got signal %d" message
        Hopefully we don't crash in the calls to 'time' or 'localtime_r'
        but if that should start to happen we can move the printout of
        time further down. At least it's now below the check for segfault

      fix for bug #19690: ORDER BY eliminates rows from the result · faad7355
      unknown authored
      Depending on the queries we use different data processing methods
      and can lose some data in case of double (and decimal in 4.1) fields.
      
      The fix consists of two parts:
      1. double comparison changed, now double a is equal to double b 
      if (a-b) is less than 5*0.1^(1 + max(a->decimals, b->decimals)). 
      For example, if a->decimals==1, b->decimals==2, a==b if (a-b)<0.005
      2. if we use a temporary table, store double values there as is 
      to avoid any data conversion (rounding).

      mysql-test/t/type_float.test:
        fix for bug #19690: ORDER BY eliminates rows from the result
          - test case
      sql/field.cc:
        fix for bug #19690: ORDER BY eliminates rows from the result
          - use not_fixed flag instead of dec to check bounds.
      sql/field.h:
        fix for bug #19690: ORDER BY eliminates rows from the result
          - Field_Double::not_fixed flag introduced, which is set if dec == NOT_FIXED_DEC
            and is used in the ::store() to check bounds. 
          - new constructor introduced (with not_fixed_arg parameter).
      sql/init.cc:
        fix for bug #19690: ORDER BY eliminates rows from the result
          - fill log_01[] array with 0.1 powers.
      sql/item_cmpfunc.cc:
        fix for bug #19690: ORDER BY eliminates rows from the result
          - compare_real_fixed() and compare_e_real_fixed() introduced,
            they consider double a == double b if a-b is less than 'precision',
            'precision' is set to 5*0.1^(1 + max(a->decimals, b->decimals)), 
            for example, if a->decimals==1, b->decimals==2, 'precision' is 0.005
          - use the above functions if both arguments are fixed.
      sql/item_cmpfunc.h:
        fix for bug #19690: ORDER BY eliminates rows from the result
          - Arg_comparator::presision introduced.
          - Arg_comparator::compare_real_fixed(), Arg_comparator::compare_e_real_fixed() introduced.
      sql/mysql_priv.h:
        fix for bug #19690: ORDER BY eliminates rows from the result
          - log_01 array of 0.1 powers added.
      sql/mysqld.cc:
        fix for bug #19690: ORDER BY eliminates rows from the result
          - log_01 array of 0.1 powers added.
      sql/sql_select.cc:
        fix for bug #19690: ORDER BY eliminates rows from the result
          - if we create double field in a temporary table, set not_fixed flag
            (use proper constructor) to avoid data conversion 
            in the Field_double::store(). Otherwise we can lose some data.

        connect phase it implies "connect-timeout"
        - Set read and write timeout value back to default after connect phase
        - Set "read_timeout" to "wait_timeout" while waiting for client.

        Set "read_timeout" to "wait_timeout" while ask other mysqld to send file
      sql-common/client.c:
        Call 'vio_timeout' to set up the read and write timeout's for the
        newly created connection. It only need to be done once at connect time.

      BUG#21915: Changing limits of table_cache when setting max_connections · 885dc1cb
      unknown authored
      If the user has specified --max-connections=N or --table-open-cache=M
      options to the server, a warning could be given that some values were
      recalculated, and table-open-cache could be assigned greater value.
      
      Note that both warning and increase of table-open-cache were totally
      harmless.
      
      This patch fixes recalculation code to ensure that table-open-cache will
      be never increased automatically and that a warning will be given only if
      some values had to be decreased due to operating system limits.
      
      No test case is provided because we neither can't predict nor control
      operating system limits for maximal number of open files.

      A fix and a test case for Bug#16365 "Prepared Statements: DoS with · 5b5530da
      unknown authored
      too many open statements". The patch adds a new global variable
      @@max_prepared_stmt_count. This variable limits the total number
      of prepared statements in the server. The default value of
      @@max_prepared_stmt_count is 16382. 16382 small statements
      (a select against 3 tables with GROUP, ORDER and LIMIT) consume 
      100MB of RAM. Once this limit has been reached, the server will 
      refuse to prepare a new statement and return ER_UNKNOWN_ERROR 
      (unfortunately, we can't add new errors to 4.1 without breaking 5.0). The limit is changeable after startup
      and can accept any value from 0 to 1 million. In case
      the new value of the limit is less than the current
      statement count, no new statements can be added, while the old
      still can be used. Additionally, the current count of prepared 
      statements is now available through a global read-only variable 
      @@prepared_stmt_count.
      
      
      mysql-test/r/ps.result:
        Test results fixed (a test case for Bug#16365)
      mysql-test/t/ps.test:
        A test case for Bug#16365 "Prepared Statements: DoS with too many 
        open statements". Also fix statement leaks in other tests.
      sql/mysql_priv.h:
        Add declarations for new global variables.
      sql/mysqld.cc:
        Add definitions of max_prepared_stmt_count, prepared_stmt_count.
      sql/set_var.cc:
        Implement support for @@prepared_stmt_count and 
        @@max_prepared_stmt_count. Currently these variables are queried
        without acquiring LOCK_prepared_stmt_count due to limitations of
        the set_var/sys_var class design. Updates are, however, protected 
        with a lock.
      sql/set_var.h:
        New declarations to add support for @@max_prepared_stmt_count.
        Implement a new class, where the lock to be used when updating
        a variable is a parameter.
      sql/sql_class.cc:
        Add accounting of the total number of prepared statements in the
        server to the methods of Statement_map.
      sql/sql_class.h:
        Add accounting of the total number of prepared statements in the
        server to the methods of Statement_map.
      sql/sql_prepare.cc:
        Statement_map::insert will now send a message in case of an
        error.

      Fix wait_timeout (and kill) handling on Mac OS X by cleaning up how · e61dea1b
      unknown authored
      signal handlers are set up, the blocking flags for sockets are set,
      and which thread-related functions are used. (Bug #8731)
      
      
      configure.in:
        Fix flags for Darwin 6 and later. Simplify Darwin 7-9 blocks to simply
        be a catch-all for *darwin* so that future Darwin releases get the
        latest flags.
      include/config-win.h:
        Define my_sigset() instead of sigset().
      include/my_pthread.h:
        Define my_sigset() instead of trying to monkey with sigset(), and favor
        an implementation based on sigaction().
      mysys/my_pthread.c:
        Remove pthread_signal(), which is identical to the new my_sigset() macro.
      mysys/thr_alarm.c:
        Use my_sigset() instead of sigset().
      sql/mysqld.cc:
        Use my_sigset() instead of signal() and sigset(), remove unnecessary
        definition of sigset on __amiga__. Remove unused THREAD_SPECIFIC_SIGPIPE
        code.
        
        A future improvement would be to re-assess the use of sigaction() here
        and convert its usage to use my_sigset().
      vio/vio.c:
        Always call fcntl() to initialize flags of socket in initialization to
        avoid problems on systems that don't report the flags on a socket
        correctly right after it has been returned from accept(), such as
        FreeBSD, Mac OS X, and possibly other BSD-derived systems.
      vio/viosocket.c:
        If fcntl() fails in vio_blocking(), restore the flags stored in the
        vio struct.
      mysql-test/r/wait_timeout.result:
        New BitKeeper file ``mysql-test/r/wait_timeout.result''
      mysql-test/t/wait_timeout-master.opt:
        New BitKeeper file ``mysql-test/t/wait_timeout-master.opt''
