This bug has been fixed in two slightly different ways in
6.0-rpl and {5.1,6.0}-bugteam. To avoid future merge
problems, I'm now copying the 6.0-rpl fix to 5.1-bugteam.

The previous fix for the bug was incomplete. The test failed
because t2 did not exist on the slave (since the slave was
lagging) when the
wait_condition was executed. Fixed by inserting
sync_slave_with_master just after t2 was created.

Test was failing due to the addition of a '\x05' character in result sets
Latest builds of the server have shown this problem to have disappeared.
Removing code within the test that disables the test on Mac OS X.

Recommit due to tree error on earlier, approved patch.

Problem: rpl_switch_stm_row_mixed did not wait until row events generated by
INSERT DELAYED were written to the master binlog before it synchronized slave
with master. This caused sporadic errors where these rows were missing on
slave.
Fix: wait until all rows appear on the slave.
This is a backport, applying the same to 5.1-bugteam as was previously
applied to 6.0-rpl

Differences in 5.1: include "/etc/mysql/" in include directories; no OS/2 support.

                  InnoDB table, where all selected columns
                  belong to the same unique index key, returns
                  incorrect results

Server executes some queries via QUICK_GROUP_MIN_MAX_SELECT
(MIN/MAX optimization for queries with GROUP BY or DISTINCT
clause) and that optimization implies loose index scan, so all
grouping is done by the QUICK_GROUP_MIN_MAX_SELECT::get_next
method.

The server does not set the precomputed_group_by flag for some
QUICK_GROUP_MIN_MAX_SELECT queries and duplicates grouping by
call to the end_send_group function.

Fix: when the test_if_skip_sort_order function selects loose 
index scan as a best way to satisfy an ORDER BY/GROUP BY type
of query, the precomputed_group_by flag has been set to use 
end_send/end_write functions instead of end_send_group/
end_write_group functions.

Bug#35658 (An empty binary value leads to mysqld crash)
        
Before this fix, the following token
  b''
caused the parser to crash when reading the binary value from the empty string.
The crash was caused by:
  ptr+= max_length - 1;
because max_length is unsigned and was 0, causing an overflow.
        
With this fix, an empty binary literal b'' is parsed as a binary value 0,
in Item_bin_string.

Normalize directory names before adding them to default_directories.


mysys/default.c:
  Normalize directory names with unpack_dirname() before adding them
  to default_directories.  This way, /etc/ and /etc will not count as
  duplicates.
  
  Because this entails allocating memory to store the normalized names,
  add error handling and ensure that it doesn't leak memory in case
  both my_print_defaults() and load_defaults() are called.
  
  Clean up the Windows code that finds the exe's parent directory, and
  pull it out into a separate function.
  
  Reorganize the code into a single init_default_directories() function,
  with internal #ifdefs, instead of init_default_directories_<system>()
  functions which were accessed via a function pointer.  This is more in
  line with normal MySQL coding style, and easier to read for some.

      The crash appeared to be a result of allocating an instance of Discrete_interval 
      automatically that that was referred in out-of-declaration scope.
                        
      Fixed with correcting backing up and restoring scheme of
      auto_inc_intervals_forced, introduced by bug#33029, by means of shallow copying;
      added simulation code that forces executing those fixes of the former bug that
      targeted at master-and-slave having incompatible bug#33029-prone versions.

mysys/stacktrace.c:
  Print stack bottom and thread stack values as they might be useful.

Another problem is that the backtrace facility wasn't being
enabled for non-Linux targets even if the target OS has the
backtrace functions. Also, the stacktrace functions inside
mysqltest were being used without proper checks for their
presence in the build.

  pack and unpack virtual methods have been overloaded for
  Field_timestamp (TIMESTAMP domain), Field_datetime (DATETIME
  domain) and Field_date (DATE domain) classes to replicate data
  between platforms with different endiannes in a correct way
  like in Field_long and Field_longlong classes.
  
  Common code have been moved to private handle_int32 and 
  handle_int64 private methods.

On a slow environment like valgrind the test is vulnerable
because it does not check if slave has stopped at time
of the new session is requested `start slave;' -- disabling
test till it is fixed.

3. Minor cleanup in some tests

The problem was that when a embedded linked version of mysqltest
crashed there was no way to obtain a stack trace if no core file
is available. Another problem is that the embedded version of
libmysql was not behaving (crash) the same as the non-embedded with
respect to sending commands to a explicitly closed connection.

The solution is to generate a mysqltest's stack trace on crash
and to enable "reconnect" if the connection handle was explicitly
closed so the behavior matches the non-embedded one.
