      WL#5408: Reduce Pushbuild2 turnaround times for rpl suite. · 2745978a
      Luis Soares authored
      This patch aims at moving some rpl tests to be run on a daily
      basis instead of running on a per push basis. To accomplish such
      goal the following modifications are proposed:
      
      - MTR: added --skip-test-list cli parameter
      
        This option allows the user to specify more than one
        disabled.def file, for example:
      
        perl mtr --skip-test-list=list1.list --skip-test-list=list2.list
      
      - Added collections/disabled-per-push.list
      
        This file lists the test cases that should be disabled per
        push.
      
      - Changed mysql-test/collections/default.push
      
        Added --skip-test-list=collections/disabled-per-push.list
        to rpl_binlog_row, ps_row and n_mix runs.
      
      - Changed mysql-test/collections/default.daily
      
        Added rpl_binlog_row run (since it is partially run per push we
        should run it fully on a daily basis).

      Patch for Bug#50511 (Sometimes wrong handling of user variables containing NULL). · d91c271b
      Alexander Nozdrin authored
            
      The bug happened under the following condition:
        - there was a user variable of type REAL, containing NULL value
        - there was a table with a NOT_NULL column of any type but REAL, having
          default value (or auto increment);
        - a row was inserted into the table with the user variable as value.
          A warning was emitted here.
      
      The problem was that handling of NULL values of REAL type was not properly
      implemented: it didn't expect that REAL NULL value can be assigned to other
      data type.
      
      Basically, the problem was that set_field_to_null() was used instead of
      set_field_to_null_with_conversions().
      
      The fix is to use the right function, or more generally, to allow conversion of
      REAL NULL values to other data types.

      Bug#51571 load xml infile causes server crash · 25d31b8f
      Alexander Barkov authored
        
        Problem:
        item->name was NULL for Item_user_var_as_out_param
        which made strcmp(something, item->name) crash in the LOAD XML code.
        
        Fix:
        - item_func.h: Adding set_name() in constuctor for Item_user_var_as_out_param
        - sql_load.cc: Changing the condition in write_execute_load_query_log_event() which
        distiguished between Item_user_var_as_out_param and Item_field
        from
          if (item->name == NULL)
        to
          if (item->type() == Item::FIELD_ITEM)
        - loadxml.result, loadxml.test: adding tests

      Bug#52849 [Com]: datetime index not work · 6bf10a86
      Alexander Barkov authored
      Problem: after introduction of "WL#2649 Number-to-string conversions"
      
      This query:
        SET NAMES cp850; -- Or any other non-latin1 ASCII-based character set
        SELECT * FROM t1
        WHERE datetime_column='2010-01-01 00:00:00'
      started to add extra character set conversion: 
        SELECT * FROM t1
        WHERE CONVERT(datetime_column USING cp850)='2010-01-01 00:00:00';
      
      so index on DATETIME column was not used anymore.
      Fix:
        avoid convertion of NUMERIC/DATETIME items
        (i.e. those with derivation DERIVATION_NUMERIC).

      Patch for Bug#52356: query_cache_debug fails on Linux. · c784ee27
      Alexander Nozdrin authored
      There were two problems here:
        1. misleading error message
        2. abusing KILL QUERY in the test case
      
      1. The server reported "'DELETE FROM t1' failed: 1689: Wait on a lock was
      aborted due to a pending exclusive lock", while the proper error message
      should be "'DELETE FROM t1' failed: 1317: Query execution was interrupted".
      
      The problem is that the server has two different flags for
      signalling that a query is being killed: THD::killed and
      mysys_var::abort. The test case triggers a race: sometimes
      mysys_var::abort is set earlier than THD::killed. That leads
      to the following situation:
      
        - thr_lock() checks mysys_var::abort and returns error status,
          since mysys_var::abort is set;
      
        - the caller (mysql_lock_tables()) gets an error from thr_lock(),
          but THD::killed is not set, so it decides that thr_lock() couldn't
          get a lock due to a pending exclusive lock.
      
      This is a known issue with the server and it's not going to be fixed soon.
      
      5.5 differs from 5.1 here as follows: when thr_lock() returns an error:
        - 5.1 continues trying thr_lock() until success;
        - 5.5 propagates the error
      
      2. The test case uses KILL QUERY is a highly concurent environment.
      
      The fix is to wait for the dying statement to rest in peace before
      executing another DELETE FROM t1.

      Bug #51839 mixup of DDL causes slave to stop · fa28ba8b
      authored
      Stored routine DDL statements use statement-based replication
      regardless of the current binlog format. The problem here was
      that if a DDL statement failed during metadata lock acquisition
      or opening of mysql.proc, the binlog format would not be reset
      before returning. So the following DDL or DML statements are 
      binlogged with a wrong binlog format, which causes the slave 
      to stop.
      
      The problem can be resolved by grabbing an exclusive MDL lock firstly
      instead of clearing the current binlog format. So that the binlog
      format will not be affected when the lock grab returns directly with
      an error. The same way is taken to open a proc table for update.

      Patch for Bug#53022: Compilation of "embedded" is broken. · 53af29c0
      Alexander Nozdrin authored
      The bug was a side effect of WL#5030 (fix header files) and
      WL#5161 (CMake).
      
      The problem was that CMake-generated config.h (and my_config.h
      as a copy of it) had a header guard. GNU autotools-generated
      [my_]config.h did not. During WL#5030 the order of header files
      was changed, so the following started to happen (using GNU autotools,
      in embedded server):
        - my_config.h included, defining HAVE_OPENSSL
        - my_global.h included, un-defining  HAVE_OPENSSL
        - zlib.h included, including config.h,
          defining HAVE_OPENSSL again.
      
      The fix is to check HAVE_OPENSSL in conjuction with EMBEDDED_LIBRARY.
      More common fix would be to define a macros as HAVE_OPENSSL && !EMBEDDED_LIBRARY
      and use it instead of HAVE_OPENSSL.

      BUG#51894 Replication failure with SBR on DROP TEMPORARY TABLE inside a · 9ba731c2
      Alfranio Correia authored
                transaction
      BUG#52616 Temp table prevents switch binlog format from STATEMENT to ROW
      
      Before the WL#2687 and BUG#46364, every non-transactional change that happened
      after a transactional change was written to trx-cache and flushed upon
      committing the transaction. WL#2687 and BUG#46364 changed this behavior and
      non-transactional changes are now written to the binary log upon committing
      the statement.
      
      A binary log event is identified as transactional or non-transactional through
      a flag in the Log_event which is set taking into account the underlie storage
      engine on what it is stems from. In the current bug, this flag was not being
      set properly when the DROP TEMPORARY TABLE was executed.
      
      However, while fixing this bug we figured out that changes to temporary tables
      should be always written to the trx-cache if there is an on-going transaction.
      Otherwise, binlog events in the reversed order would be produced.
      
      Regarding concurrency, keeping changes to temporary tables in the trx-cache is
      also safe as temporary tables are only visible to the owner connection.
      
      In this patch, we classify the following statements as unsafe:
         1 - INSERT INTO t_myisam SELECT * FROM t_myisam_temp
      
         2 - INSERT INTO t_myisam_temp SELECT * FROM t_myisam
      
         3 - CREATE TEMPORARY TABLE t_myisam_temp SELECT * FROM t_myisam
      
      On the other hand, the following statements are classified as safe:
      
         1 - INSERT INTO t_innodb SELECT * FROM t_myisam_temp
      
         2 - INSERT INTO t_myisam_temp SELECT * FROM t_innodb
      
      The patch also guarantees that transactions that have a DROP TEMPORARY are
      always written to the binary log regardless of the mode and the outcome:
      commit or rollback. In particular, the DROP TEMPORARY is extended with the
      IF EXISTS clause when the current statement logging format is set to row.
      
      Finally, the patch allows to switch from STATEMENT to MIXED/ROW when there
      are temporary tables but the contrary is not possible.
