      Bug#19671 mysql_list_fields returns incorrect table name for VIEWs · bffd7752
      unknown authored
      After view onening real view db name and table name are placed
      into table_list->view_db & table_list->view_name.
      Item_field class does not handle these names properly during 
      intialization of Send_field.
      The fix is to use new class 'Item_ident_for_show' 
      which sets correct view db name and table name for Send_field.

      This finishes bug#18516, as far as "generic RPMs" are concerned.
      
      
      support-files/mysql.spec.sh:
        Revert all previous attempts to call "mysql_upgrade" during RPM upgrade,
        there are some more aspects which need to be solved before this is possible.
        For now, just ensure the binary "mysql_upgrade" is delivered and installed.
        This finishes bug#18516, as far as "generic RPMs" are concerned.

      Fix a minor issue with Bug#16206 (bdb.test failed if the tree is compiled

        Change declaration of my_strdup_with_length to accept const char *,

        Change the type of db_length to uint from uint32: LEX_STRING uses uint for

        minimize cast and compile failures.

      A fix and a test case for · 2783fc82
      unknown authored
       Bug#19022 "Memory bug when switching db during trigger execution"
       Bug#17199 "Problem when view calls function from another database."
       Bug#18444 "Fully qualified stored function names don't work correctly in
                  SELECT statements"
      
       Documentation note: this patch introduces a change in behaviour of prepared
       statements.
      
       This patch adds a few new invariants with regard to how THD::db should
       be used. These invariants should be preserved in future:
      
        - one should never refer to THD::db by pointer and always make a deep copy
          (strmake, strdup)
        - one should never compare two databases by pointer, but use strncmp or
          my_strncasecmp
        - TABLE_LIST object table->db should be always initialized in the parser or
          by creator of the object.
      
          For prepared statements it means that if the current database is changed
          after a statement is prepared, the database that was current at prepare
          remains active. This also means that you can not prepare a statement that
          implicitly refers to the current database if the latter is not set.
          This is not documented, and therefore needs documentation. This is NOT a
          change in behavior for almost all SQL statements except:
           - ALTER TABLE t1 RENAME t2 
           - OPTIMIZE TABLE t1
           - ANALYZE TABLE t1
           - TRUNCATE TABLE t1 --
           until this patch t1 or t2 could be evaluated at the first execution of
           prepared statement. 
      
           CURRENT_DATABASE() still works OK and is evaluated at every execution
           of prepared statement.
      
           Note, that in stored routines this is not an issue as the default
           database is the database of the stored procedure and "use" statement
           is prohibited in stored routines.
      
        This patch makes obsolete the use of check_db_used (it was never used in the
        old code too) and all other places that check for table->db and assign it
        from THD::db if it's NULL, except the parser.
      
       How this patch was created: THD::{db,db_length} were replaced with a
       LEX_STRING, THD::db. All the places that refer to THD::{db,db_length} were
       manually checked and:
        - if the place uses thd->db by pointer, it was fixed to make a deep copy
        - if a place compared two db pointers, it was fixed to compare them by value
          (via strcmp/my_strcasecmp, whatever was approproate)
       Then this intermediate patch was used to write a smaller patch that does the
       same thing but without a rename.
      
       TODO in 5.1:
         - remove check_db_used
         - deploy THD::set_db in mysql_change_db
      
       See also comments to individual files.
      
      
      mysql-test/r/create.result:
        Modify the result file: a database can never be NULL.
      mysql-test/r/ps.result:
        Update test results (Bug#17199 et al)
      mysql-test/r/sp.result:
        Update test results (Bug#17199 et al)
      mysql-test/t/create.test:
        Update the id of the returned error.
      mysql-test/t/ps.test:
        Add test coverage for prepared statements and current database. In scope of
        work on Bug#17199 "Problem when view calls function from another database."
      mysql-test/t/sp.test:
        Add a test case for Bug#17199 "Problem when view calls function from another
        database." and Bug#18444 "Fully qualified stored function names don't work
        correctly in SELECT statements". Test a complementary problem.
      sql/item_strfunc.cc:
        Touch the code that reads thd->db (cleanup).
      sql/log_event.cc:
        While we are at it, replace direct access to thd->db with a method.
        Should simplify future conversion of THD::db to LEX_STRING.
      sql/slave.cc:
        While we are at it, replace direct access to thd->db with a method.
        Should simplify future conversion of THD::db to LEX_STRING.
      sql/slave.h:
        Remove a declaration for a method that is used only in one module.
      sql/sp.cc:
        Rewrite sp_use_new_db: this is a cleanup that I needed in order to understand
        this function and ensure that it has no bugs.
      sql/sp.h:
        Add a new declaration for sp_use_new_db (uses LEX_STRINGs) and a comment.
      sql/sp_head.cc:
        - drop sp_name_current_db_new - a creator of sp_name class that was used
        when sp_name was created for an identifier without an explicitly initialized
        database. Now we pass thd->db to constructor of sp_name right in the 
        parser.
        - rewrite sp_head::init_strings: name->m_db is always set now
        - use the new variant of sp_use_new_db
        - we don't need to update thd->db with SP MEM_ROOT pointer anymore when
        parsing a stored procedure, as noone will refer to it (yes!)
      sql/sp_head.h:
        - remove unneded methods and members
      sql/sql_class.h:
        - introduce 3 THD  methods to work with THD::db:
          .set_db to assign the current database
          .reset_db to reset the current database (temporarily) or set it to NULL
          .opt_copy_db_to - to deep-copy thd->db to a pointer if it's not NULL
      sql/sql_db.cc:
        While we are at it, replace direct access to thd->db with a method.
        Should simplify future conversion of THD::db to LEX_STRING.
      sql/sql_insert.cc:
        - replace checks with asserts: table_list->db must be always set in the parser.
      sql/sql_lex.h:
        - add a comment
      sql/sql_parse.cc:
        - implement the invariant described in the changeset comment.
        - remove juggling with lex->sphead in SQLCOM_CREATE_PROCEDURE:
          now db_load_routine uses its own LEX object and doesn't damage the main
          LEX.
        - add DBUG_ASSERT(0) to unused "check_db_used"
      sql/sql_table.cc:
        - replace a check with an assert (table_ident->db)
      sql/sql_trigger.cc:
        While we are at it, replace direct access to thd->db with a method.
        Should simplify future conversion of THD::db to LEX_STRING.
      sql/sql_udf.cc:
        - use thd->set_db instead of direct modification of to thd->db
      sql/sql_view.cc:
        - replace a check with an assert (view->db)
      sql/sql_yacc.yy:
        - make sure that we always copy table->db or name->db or ident->db or
          select_lex->db from thd->db if the former is not set. If thd->db
          is not set but is accessed, return an error.
      sql/tztime.cc:
        - be nice, never copy thd->db by pointer.

      Bug#16986 - Deadlock condition with MyISAM tables · e6d5fe0f
      unknown authored
      Addendum fixes after changing the condition variable
      for the global read lock.
      
      The stress test suite revealed some deadlocks. Some were
      related to the new condition variable (COND_global_read_lock)
      and some were general problems with the global read lock.
      
      It is now necessary to signal COND_global_read_lock whenever 
      COND_refresh is signalled.
      
      We need to wait for the release of a global read lock if one 
      is set before every operation that requires a write lock.
      But we must not wait if we have locked tables by LOCK TABLES.
      After setting a global read lock a thread waits until all
      write locks are released.

      Fix race condition in test case wait_timeout. · d0d405ee
      unknown authored
      Sometimes the helper connection (that is watching for the main connection
      to time out) would itself time out first, causing the test to fail.
      
      
      mysql-test/t/wait_timeout.test:
        Increase connection timeout in connection wait_con so we will not loose
        the connection that is watching for the real wait_timeout to trigger.
