      Bug#11889186 60503: CRASH IN MAKE_DATE_TIME WITH DATE_FORMAT / STR_TO_DATE COMBINATION · a60c39a2
      Sergey Glukhov authored
      calc_daynr() function returns negative result
      if malformed date with zero year and month is used.
      Attempt to calculate week day on negative value
      leads to crash. The fix is return NULL for
      'W', 'a', 'w' specifiers if zero year and month is used.
      Additional fix for calc_daynr():
      --added assertion that result can not be negative
      --return 0 if zero year and month is used

      Bug#11756928 48916: SERVER INCORRECTLY PROCESSING HAVING CLAUSES WITH AN ORDER BY CLAUSE · a5e8d902
      Sergey Glukhov authored
      Before sorting HAVING condition is split into two parts,
      first part is a table related condition and the rest of is
      HAVING part. Extraction of HAVING part does not take into account
      the fact that some of conditions might be non-const but
      have 'used_tables' == 0 (independent subqueries)
      and because of that these conditions are cut off by
      make_cond_for_table() function.
      The fix is to use (table_map) 0 instead of used_tables in
      third argument for make_cond_for_table() function.
      It allows to extract elements which belong to sorted
      table and in addition elements which are independend
      subqueries.

      Bug#11766249 bug#59316: PARTITIONING AND INDEX_MERGE MEMORY LEAK · bd92ea43
      Mattias Jonsson authored
      Update for previous patch according to reviewers comments.
      
      Updated the constructors for ha_partitions to use the common
      init_handler_variables functions
      
      Added use of defines for size and offset to get better readability for the code that reads
      and writes the .par file. Also refactored the get_from_handler_file function.

      BUG#12377872 ASSERTION FAILED: !_ENTERED WHEN GETHOSTBYADDR_R · f3b024ca
      Jon Olav Hauglid authored
                   FAILS ON SOLARIS
      
      This assertion was triggered if gethostbyaddr_r cannot do a
      reverse lookup on an ip address. The reason was a missing
      DBUG_RETURN macro. The problem affected only debug versions of
      the server.
      
      This patch fixes the problem by replacing return with DBUG_RETURN.
      No test case added.

      Bug#11765923 58937: MANY VALGRIND ERRORS AFTER GROUPING BY RESULT OF DECIMAL COLUMN FUNCTION · 90bbf9d6
      Sergey Glukhov authored
      Bug#11764671  57533: UNINITIALISED VALUES IN COPY_AND_CONVERT (SQL_STRING.CC) WITH CERTAIN CHA
      When ROUND evaluates decimal result it uses Item::decimal
      value as fraction value for the result. In some cases
      Item::decimal is greater than real result fraction value
      and uninitialised memory of result(decimal) buffer can be
      used in further calculations. Issue is introduced by
      Bug33143 fix. The fix is to remove erroneous assignment.

        If we have a non-nullable index, we cannot use it to match null values,
        since set_null() will be ignored, and we might compare uninitialized data.

      Bjorn Munch authored
      Fix for --vs-config applied
      Find.pm incorrectly tested an unitialized local variable instead
        of the global, corrected.
      Find.pm is also wrong in 5.5: uses a non-existent global variable. Fix when
        merging up.

      Bug#11756242 48137: PROCEDURE ANALYSE() LEAKS MEMORY WHEN RETURNING NULL · 3abe56f3
      Sergey Glukhov authored
      There are two problems with ANALYSE():
      
      1. Memory leak 
         it happens because do_select() can overwrite
         JOIN::procedure field(with zero value in our case) and
         JOIN destructor don't free the memory allocated for
         JOIN::procedure. The fix is to save original JOIN::procedure
         before do_select() call and restore it after do_select
         execution.
      
      2. Wrong result
         If ANALYSE() procedure is used for the statement with LIMIT clause
         it could retrun empty result set. It happens because of missing 
         analyse::end_of_records() call. First end_send() function call
         returns NESTED_LOOP_QUERY_LIMIT and second call of end_send() with
         end_of_records flag enabled does not happen. The fix is to return
         NESTED_LOOP_OK from end_send() if procedure is active.

          restore it after do_select execution.
        --return NESTED_LOOP_OK from end_send() if procedure is active
