      Bug #20748: Configuration files should not be read more than once · 707f42a6
      unknown authored
      A user could not override system-wide settings in their ~/.my.cnf,
      because the DEFAULT_SYSCONFDIR was being searched last.  Also, in
      some configurations (especially when the --sysconfdir compile-time
      option is set to /etc or /etc/mysql), the system-wide my.cnf file
      was read multiple times, causing confusion and potential problems.
      
      Rearrange default directories to conform to the manual and logic.
      Move --sysconfdir=<path> (DEFAULT_SYSCONFDIR) from the last default
      directory to the middle of the list.  $HOME/.my.cnf should be last,
      so the user is able to override the system-wide settings.
      
      Change init_default_directories() to remove duplicates from the
      list.
      
      
      include/my_sys.h:
        Add array_append_string_unique(), from mf_arr_appstr.c
      libmysql/Makefile.shared:
        Add new mf_arr_appstr.lo object
      mysys/CMakeLists.txt:
        Add new mf_arr_appstr.c source.
      mysys/Makefile.am:
        Add new mf_arr_appstr.c source.
      mysys/default.c:
        Change order in which defaults files are added to default_directories,
        in order to conform to the manual (and to common sense).  This fixes
        a particularly bad problem on Unix, where ~/.my.cnf was read before
        /usr/local/etc/my.cnf.
        
        Also, don't add duplicate entries; move the existing entry to the
        end of the list instead.
        
        
        Here is a comparison of the order of defaults files, BEFORE and AFTER
        this patch.
        
        On Windows:
        
        BEFORE:  C:\, GetWindowsDirectory(), GetSystemWindowsDirectory(),
                 $MYSQL_HOME, defaults-extra-file, INSTALLDIR
        
        AFTER:  GetSystemWindowsDirectory(), GetWindowsDirectory(), C:\,
                INSTALLDIR, $MYSQL_HOME, defaults-extra-file
        
        GetSystemWindowsDirectory() is moved before GetWindowsDirectory() because
        the former is shared by all Terminal Services users, while the latter is
        private for each user.
        
        
        On Netware (no change):
        
        BEFORE:  sys:/etc/, $MYSQL_HOME, defaults-extra-file
        
        AFTER:  sys:/etc, $MYSQL_HOME, defaults-extra-file
        
        
        On OS/2:
        
        BEFORE:  $ETC, /etc, $MYSQL_HOME, defaults-extra-file
        
        AFTER:  /etc, $ETC, $MYSQL_HOME, defaults-extra-file
        
        
        On everything else (general Unix):
        
        BEFORE:  /etc, $MYSQL_HOME, defaults-extra-file, ~/, --sysconfdir
        
        AFTER:  /etc/, --sysconfdir, $MYSQL_HOME, defaults-extra-file, ~/
        
        The BEFORE code added --sysconfdir on all systems, but only the
        Unix build system actually defined a value for it.

      Cast away compiler warning on Windows. · 8680f86e

        Cast away a compiler warning; some functions return ulong or ulint for
        errors, and some use int.  Let's hope these all fit in an int.

      Bug #31860: Server crashes after inserting into InnoDB table with auto_increment column

        autoincrement table counter is set to 0 if the maximum value read from

      Fixes the following bugs:
      
      Bug #30706: SQL thread on slave is allowed to block client queries when slave load is high
        Add (innodb|innobase|srv)_replication_delay MySQL config parameter.
      
      Bug #30888: Innodb table + stored procedure + row deletion = server crash
        While adding code for the low level read of the AUTOINC value from the index,
        the case for MEDIUM ints which are 3 bytes was missed triggering an
        assertion.
      
      Bug #30907: Regression: "--innodb_autoinc_lock_mode=0" (off) not same as older releases
        We don't rely on *first_value to be 0 when checking whether
        get_auto_increment() has been invoked for the first time in a multi-row
        INSERT. We instead use trx_t::n_autoinc_rows. Initialize trx::n_autoinc_rows
        inside ha_innobase::start_stmt() too.
      
      Bug #31444: "InnoDB: Error: MySQL is freeing a thd" in innodb_mysql.test
        ha_innobase::external_lock(): Update prebuilt->mysql_has_locked and
        trx->n_mysql_tables_in_use only after row_lock_table_for_mysql() returns
        DB_SUCCESS.  A timeout on LOCK TABLES would lead to an inconsistent state,
        which would cause trx_free() to print a warning.
      
      Bug #31494: innodb + 5.1 + read committed crash, assertion
        Set an error code when a deadlock occurs in semi-consistent read.

        Fixed bug#28404.
        This patch adds cost estimation for the queries with ORDER BY / GROUP BY
        and LIMIT.
        If there was a ref/range access to the table whose rows were required
        to be ordered in the result set the optimizer always employed this access
        though a scan by a different index that was compatible with the required
        order could be cheaper to produce the first L rows of the result set.
        Now for such queries the optimizer makes a choice between the cheapest
        ref/range accesses not compatible with the given order and index scans
        compatible with it.

        Revision r1873:
        snprintf() should always return non-negative result. According to
        Microsoft documentation about _vscprintf():
        
          If format is a null pointer, the invalid parameter handler is invoked,
          as described in Parameter Validation. If execution is allowed to
          continue, the functions return -1 and set errno to EINVAL.
        
        The UNIX variant of snprintf() segfaults if format is a NULL pointer
        (similar to strlen(NULL) for example), so it is better to conform to
        this behavior and crash our custom Windows version instead of
        returning -1. Noone would expect -1 to be returned from snprintf().

      A fix for Bug#32030 "DELETE does not return an error and deletes rows if · 0c1bdcbd
      unknown authored
      error evaluating WHERE"
      
      DELETE with a subquery in WHERE clause would sometimes ignore subquery
      evaluation error and proceed with deletion.
      
      The fix is to check for an error after evaluation of the WHERE clause
      in DELETE.
      
      Addressed review comments.

      Bug#30882 Dropping a temporary table inside a stored function may cause a server crash · 611dbd0b
      unknown authored
      If a stored function that contains a drop temporary table statement
      is invoked by a create temporary table of the same name may cause
      a server crash. The problem is that when dropping a table no check
      is done to ensure that table is not being used by some outer query
      (or outer statement), potentially leaving the outer query with a
      reference to a stale (freed) table.
      
      The solution is when dropping a temporary table, always check if
      the table is being used by some outer statement as a temporary
      table can be dropped inside stored procedures.
      
      The check is performed by looking at the TABLE::query_id value for
      temporary tables. To simplify this check and to solve a bug related
      to handling of temporary tables in prelocked mode, this patch changes
      the way in which this member is used to track the fact that table is
      used/unused. Now we ensure that TABLE::query_id is zero for unused
      temporary tables (which means that all temporary tables which were
      used by a statement should be marked as free for reuse after it's
      execution has been completed).

      sql/event_db_repository.cc:
        Update close_thread_tables call, no more default values.
      sql/mysql_priv.h:
        Remove implicit default parameters values of the close_thread_tables
        function as no callers are using it.
      sql/slave.cc:
        Update close_thread_tables call, no more default values
      sql/sp_head.cc:
        Update close_thread_tables call, no more default values
      sql/sql_base.cc:
        Changed the approach to distinguishing currently unused temporary tables.
        Now we ensure that such tables always have TABLE::query_id set to 0 and
        use this fact to perform checks during opening and dropping of temporary
        tables. This means that we have to call close_thread_tables() even for
        statements which use only temporary tables. To make this call cheaper,
        we re-factored close_thread_tables() to not take LOCK_open unless there
        are open base tables.
      sql/sql_handler.cc:
        Properly close temporary tables associated with a handler.
      sql/sql_insert.cc:
        close_temporary_table is now merged into drop_temporary_table.
      sql/sql_parse.cc:
        Now the condition doesn't cover all cases because close_thread_tables()
        must be called even for statements that use only temporary tables.
      sql/sql_table.cc:
        Use drop_temporary_table which perform checks to verify if
        the table is not being used. Error path problem is due to
        a handler tables issue and is going to be addressed in bug
        31397.
      sql/table.h:
        Rename previously unused clear_query_id and document the usage of
        query_id and open_by_handler.

      Bug#31850 Test crashes in "embedded" server · 8f0df2ef
      unknown authored
      The mysql_change_user command fails to properly update the database pointer
      when no database is selected, leading to "use after free" errors. The same
      happens on the user privilege pointer in the thread security context.
      
      The solution is to properly reset and update the database name. Also update
      the user_priv pointer so that it doesn't point to freed memory.
      
      
      sql/sql_connect.cc:
        After a successful call to check_user() without specifying a new
        database name, the previous database thd->db) is freed but the
        pointer is not updated to NULL.
      sql/sql_parse.cc:
        Update the security_ctx->priv_user pointer as it is a alias for
        the user security_ctx->user pointer. Also remove unneeded cast,
        the x_free macro casts the argument.

      Cleanup execute_ddl_log_recovery() to not generate an error if · 6dd04c22
      unknown authored
      there is nothing to recover.
      
      Discovered while working on Bug#12713
      
      
      sql/sql_table.cc:
        Use MYF(0) in my_open() in read_ddl_log_header() called from
        execute_ddl_log_recovery() called during the server start up to not
        generate an error if no ddl log exists. This is not an erroneous situation,
        in fact it's the case in any server statrtup. The error was lost
        anyway, since it was pushed into the stack of the artificial thd.
