Temporary tables may set join->group to 0 even though there is 
grouping. Also need to test if sum_func_count>0 when JOIN::exec() 
decides whether to present results in a grouped manner.

sql/sql_select.cc:
  Temporary tables may set join->group to 0 even though there is 
  grouping. Also need to test if sum_func_count>0 when JOIN::exec() 
  decides whether to present results in a grouped manner.

            columns without where/group
                     
Simple SELECT with implicit grouping used to return many rows if
the query was ordered by the aggregated column in the SELECT
list. This was incorrect because queries with implicit grouping
should only return a single record.
                              
The problem was that when JOIN:exec() decided if execution needed
to handle grouping, it was assumed that sum_func_count==0 meant
that there were no aggregate functions in the query. This
assumption was not correct in JOIN::exec() because the aggregate
functions might have been optimized away during JOIN::optimize().
                  
The reason why queries without ordering behaved correctly was
that sum_func_count is only recalculated if the optimizer chooses
to use temporary tables (which it does in the ordered case).
Hence, non-ordered queries were correctly treated as grouped.
                  
The fix for this bug was to remove the assumption that
sum_func_count==0 means that there is no need for grouping. This
was done by introducing variable "bool implicit_grouping" in the
JOIN object.

The BINLOG statement was sharing too much code with the slave SQL thread, introduced with
the patch for Bug#32407. This caused statements to be logged with the wrong server_id, the
id stored inside the events of the BINLOG statement rather than the id of the running 
server.
      
Fix by rearranging code a bit so that only relevant parts of the code are executed by
the BINLOG statement, and the server_id of the server executing the statements will 
not be overrided by the server_id stored in the 'format description BINLOG statement'.

mysql-test/extra/binlog_tests/binlog.test:
  Added test to verify if the server_id stored in the 'format 
  description BINLOG statement' will override the server_id
  of the server executing the statements.

  Moved rows_event_stmt_clean() call from update_pos() to apply_event(). This in any case

  BINLOG statements.
sql/slave.cc:
  The skip flag is no longer needed, as the code path for BINLOG statement has been 
  cleaned up.
sql/sql_binlog.cc:
  Don't invoke the update_pos() code path for the BINLOG statement, as it contains code 
  that is redundant and/or harmful (especially setting thd->server_id).

 
The problem was in incorrect handling of predicates involving 
NULL as a constant value by the range optimizer.  
 
For example, when creating a SEL_ARG node from a condition of 
the form "field < const" (which would normally result in the 
"NULL < field < const" SEL_ARG),  the special case when "const" 
is NULL was not taken into account, so "NULL < field < NULL" 
was produced for the "field < NULL" condition. 
 
As a result, SEL_ARG structures of this form could not be 
further optimized which in turn could lead to incorrectly 
constructed SEL_ARG trees. In particular, code assuming SEL_ARG 
structures to always form a sequence of ordered disjoint 
intervals could enter an infinite loop under some 
circumstances. 
 
Fixed by changing get_mm_leaf() so that for any sargable 
predicate except "<=>" involving NULL as a constant, "empty" 
SEL_ARG is returned, since such a predicate is always false. 

mysql-test/r/range.result:
  Added a test case for bug #47123.
mysql-test/t/range.test:
  Added a test case for bug #47123.

mysql-test/std_data/latin1.xml:
  Bug#46448 trailing spaces are not ignored when user collation maps space != 0x20
  
  Fixing copy right header in test collation file.

In MySQL when the mapping for space is changed to something other than
0x20 by defining a different collation, then space is not ignored when
comparing two strings.

This was happening because the function that performs the comparison
of two strings while ignoring ending spaces, was comparing the collation
value of a space with the ascii value of the ' ' character. This should
be changed to do comparison between the collated values.

  value and the ascii value.

  A build "--without-server" fails if using "--with-ssl" (YaSSL)

The problem was the lack of directory "extra" in a build
which did not include the server.

configure.in:
  1) Ensure "extra" is in the list of client directories.
  2) Always handle the client directories first, as they will
     be contained in every build (we have client-only, but not
     server-only).

            low myisam_sort_buffer_size

Repair by sort (default) or parallel repair of a MyISAM table
(doesn't matter partitioned or not) as well as bulk inserts
and enable indexes some times didn't failover to repair with
key cache.

The problem was that after unsuccessful attempt, data file was
closed. Whereas repair with key cache requires open data file.
Fixed by reopening data file.

Also fixed a valgrind warning, which may appear during repair
by sort or parallel repair with certain myisam_sort_buffer_size
number of rows and length of an index entry (very dependent).

mysql-test/r/myisam.result:
  A test case for BUG#47073.
mysql-test/t/myisam.test:
  A test case for BUG#47073.
storage/myisam/ha_myisam.cc:
  Reverted fix for BUG25289. Not needed anymore.
storage/myisam/mi_check.c:
  Reopen data file, when repair by sort or parallel repair
  fails.
  
  When repair by sort is requested to rebuild data file, data file
  gets rebuilt while fixing first index. When rebuild is completed,
  info->dfile is pointing to temporary data file, original data file
  is closed.
  
  It may happen that repair has successfully fixed first index and
  rebuilt data file, but failed to fix second index. E.g.
  myisam_sort_buffer_size was big enough to fix first shorter index,
  but not enough to fix subsequent longer index.
  
  In this case we end up with info->dfile pointing to temporary file,
  which is removed and info->dfile is set to -1.
  
  Though repair by sort failed, the upper layer may still want to
  try repair with key cache. But it needs info->dfile pointing to
  valid data file.
storage/myisam/sort.c:
  When performing a copy of IO_CACHE structure, current_pos and
  current_end must be updated separatly to point to memory we're
  copying to (not to memory we're copying from).
  
  As t_file2 is always WRITE cache, proper members are write_pos
  and write_end accordingly.

branches/zip: Clean up after a crash during DROP INDEX.
When InnoDB crashes while dropping an index, ensure that
the index will be completely dropped during crash recovery.

row_merge_drop_index(): Before dropping an index, rename the index to
start with TEMP_INDEX_PREFIX_STR and commit the change, so that
row_merge_drop_temp_indexes() will drop the index after crash
recovery if the server crashes while dropping the index.

fseg_inode_try_get(): New function, forked from fseg_inode_get().
Return NULL if the file segment index node is free.

fseg_inode_get(): Assert that the file segment index node is not free.

fseg_free_step(): If the file segment index node is already free,
print a diagnostic message and return TRUE.

fsp_free_seg_inode(): Write a nonzero number to FSEG_MAGIC_N, so that
allocated-and-freed file segment index nodes can be better
distinguished from uninitialized ones.

This is rb://174, addressing Issue #348.

Tested by restarting mysqld upon the completion of the added
log_write_up_to() invocation below, during DROP INDEX.  The index was
dropped after crash recovery, and re-issuing the DROP INDEX did not
crash the server.
