      Bug #30286 spatial index cause corruption and server crash! · ffdd1f61
      unknown authored
      As the result of DOUBLE claculations can be bigger
      than DBL_MAX constant we use in code, we shouldn't use this constatn
      as a biggest possible value.
      Particularly the rtree_pick_key function set 'min_area= DBL_MAX' relying
      that any rtree_area_increase result will be less so we return valid
      key. Though in rtree_area_increase function we calculate the area
      of the rectangle, so the result can be 'inf' if the rectangle is
      huge enough, which is bigger than DBL_MAX.
      
      Code of the rtree_pick_key modified so we always return a valid key.

      which does not work.  Removing these attempted privileges makes
      this identical to option 5 so remove it completely.  The spirit
      of the program appears to be aimed at database privileges, so do
      not add another option for granting global privileges as it may
      be unexpected.  Fixes bug#14618 (same as previous patch, this

      Bug#29838 - myisam corruption using concurrent select ... and update · 7dc16f2e
      unknown authored
      When using concurrent insert with parallel index reads, it could
      happen that reading sessions found keys that pointed to records
      yet to be written to the data file. The result was a report of
      a corrupted table. But it was false alert.
      
      When inserting a record in a table with indexes, the keys are
      inserted into the indexes before the record is written to the data
      file. When the insert happens concurrently to selects, an
      index read can find a key that references the record that is not
      yet written to the data file. To avoid any access to such record,
      the select saves the current end of file position when it starts.
      Since concurrent inserts are always appended at end of the data
      file, the select can easily ignore any concurrently inserted record.
      
      The problem was that the ignore was only done for non-exact key
      searches (partial key or using >, >=, < or <=).
      
      The fix is to ignore concurrently inserted records also for
      exact key searches.
      
      No test case. Concurrent inserts cannot be tested with the test
      suite. Test cases are attached to the bug report.

      Bug #29717 INSERT INTO SELECT inserts values even if · 86ae8436
      unknown authored
       SELECT statement itself returns empty.
      
      As a result of this bug 'SELECT AGGREGATE_FUNCTION(fld) ... GROUP BY'
      can return one row instead of an empty result set.
      
      When GROUP BY only has fields of constant tables
      (with a single row), the optimizer deletes the group_list.
      After that we lose the information about whether we had an
      GROUP BY statement. Though it's important
      as SELECT min(x) from empty_table; and
         SELECT min(x) from empty_table GROUP BY y; have to return
      different results - the first query should return one row,
      second - an empty result set.
      So here we add the 'group_optimized_away' flag to remember this case
      when GROUP BY exists in the query and is removed
      by the optimizer, and check this flag in end_send_group()

      Raise the 64 character limit for path names in the error messages · 08a3c0ff
      unknown authored
      to 150 or 107 characters for those messages which are generated
      by the embedded server during release builds.
      
      This fixes bug#16635:
         Error messages wrong: absolute path names, "%s" format code
      
      See the bug report or the changelog for "sql/share/english/errmsg.txt"
      for instructions how to do that with other languages, 
      even at the customer site, and for the restrictions to keep.
      
      
      sql/share/english/errmsg.txt:
        The embedded server uses absolute path names in its error messages,
        in the release build environment these exceed the 64 character limit
        which the format strings for the error messages impose (bug#16635).
        
        But when the messages are output, the server does the "printf()" 
        internally in a 256 character buffer; the constant text and the
        expanded variables (strings, error number) must fit into this.
        
        (If the buffer would overflow, a format specification will not be
        expanded but just copied with its code, and the message output
        will just contain '%s' or '%d' where a value is expected.)
        
        So the string lengths are increased to 150 characters in those messages
        which are issued by the embedded server during release tests
        and contain 1 (one) path name,
        but only to 107 in the "rename" message which contains 2 (two).
        
        This solves bug#16635 for the release builds.
        
        For other languages used by OEM customers, similar fixes may be needed,
        but we cannot test them.
        
        These fixes can be done even in a binary installation at the customer site
        by following these steps:
           cd <<install-root>>/share
           $EDITOR <<lang>>/errmsg.txt
           ../../bin/comp_err -C./charsets/ <<lang>>/errmsg.txt <<lang>>/errmsg.sys
        and then restarting the server.

      Fixed bug #29911. · 5db49605
      unknown authored
      This bug manifested itself for join queries with GROUP BY and HAVING clauses
      whose SELECT lists contained DISTINCT. It occurred when the optimizer could
      deduce that the result set would have not more than one row.
      The bug could lead to wrong result sets for queries of this type because
      HAVING conditions were erroneously ignored in some cases in the function
      remove_duplicates.

      Bug#27198: Error returns from time() are ignored · 200550db
      unknown authored
      gettimeofday() can fail and presumably, so can time().
      Keep an eye on it.
      
      Since we have no data on this at all so far, we just
      retry on failure (and log the event), assuming that
      this is just an intermittant failure. This might of
      course hang the threat until we succeed. Once we know
      more about these failures, an appropriate more clever
      scheme may be picked (only try so many times per thread,
      etc., if that fails, return last "good" time() we got or
      some such).  Using sql_print_information() to log as this
      probably only occurs in high load scenarios where the debug-
      trace likely is disabled (or might interfere with testing
      the effect).  No test-case as this is a non-deterministic
      issue.
      
      
      sql/mysql_priv.h:
        Bug#27198: Error returns from time() are ignored
        
        move declarations for log.cc to before inclusion of
        sql_class.h as we now use sql_print_information() in
        there.
