This involves merge changesets and backports into QSP builds only,

not ready to run with innoplug-1.0.4.

automerge didn't handle this correctly,
so test "view" was corrected manually.

The test for the 45806 entry in our bug DB got applied twice,
in different places for the "view.test" and "view.result" files.

The fix is to simply remove the erroneous insertion.

widely used, in replication (delete_allow_opened) and for named
pipe support. We do not support Win9x anymore.

The problem is that the lexer could inadvertently skip over the
end of a query being parsed if it encountered a malformed multibyte
character. A specially crated query string could cause the lexer
to jump up to six bytes past the end of the query buffer. Another
problem was that the laxer could use unfiltered user input as
a signed array index for the parser maps (having upper and lower
bounds 0 and 256 respectively).

The solution is to ensure that the lexer only skips over well-formed
multibyte characters and that the index value of the parser maps
is always a unsigned value.

mysql-test/r/ctype_recoding.result:
  Update test case result: ending backtick is not skipped over anymore.
sql/sql_lex.cc:
  Characters being analyzed must be unsigned as they can be
  used as indexes for the parser maps. Only skip over if the
  string is a valid multi-byte sequence.

Problem 1:
When the 'Using index' optimization is used, the optimizer may still - after
cost-based optimization - decide to use another index in order to avoid using
a temporary table. But when this happens, the flag to the storage engine to 
read index only (not table) was still set. Fixed by resetting the flag in the 
storage engine and TABLE structure in the above scenario, unless the new index
allows for the same optimization.
Problem 2:
When a 'ref' access method was employed by cost-based optimizer, (when the column
is non-NULLable), it was assumed that it needed no initialization if 'quick' access
methods (since they are based on range scan). When ORDER BY optimization overrides 
the decision, however, it expects to have this initialized and hence crashes. 
Fixed in 5.1 (was fixed in 6.0 already) by initializing 'quick' even when there's 
'ref' access.

                    column on partitioned table
      
      
An assertion 'ASSERT_COULUMN_MARKED_FOR_READ' is failed if the query 
is executed with index containing double column on partitioned table.
The problem is that assertion expects all the fields which are read,
to be in the read_set.
      
In this query only the field 'a' is in the readset as the tables in
the query are joined by the field 'a' and so the assertion fails 
expecting other field 'b'.
      
Since the function cmp() is just comparison of two parameters passed, 
the assertion is not required.
      
Fixed by removing the assertion in the double fields comparision
function and also fixed the index initialization to do ordered
index scan with RW LOCK which ensures all the fields from a key are in
the read_set.
 

Note: this bug is not reproducible with other datatypes because the
      assertion doesn't exist in comparision function for other 
      datatypes.

The server shutdown and start code triggered the valgrind failures 
within nptl_pthread_exit_hack_handler on Ubuntu 9.04, x86 (but not amd64) 
in rpl_trigger.test file.

For fixing the bug, suppress valgrind failures within nptl_pthread_exit_hack_handler 
on Ubuntu 9.04, x86 (but not amd64). Because the server shutdown and start
code has been heavily used in mysql test set.

mysql-test/valgrind.supp:
  Add code for suppressing valgrind failures within nptl_pthread_exit_hack_handler on Ubuntu 9.04, x86 (but not amd64).

Reverted lost in the merge line.

Install procedure does not copy *.inc files located under the mysql-test/t directory.
Therefore, this patch moves the rpl_trigger.inc to the mysql-test/include directory.

The test case fails sporadically on Windows while trying to overwrite an unused
binary log. The problem stems from the fact that MySQL on Windows does not
immediately unlock/release a file while the process that opened and closed it is
still running. In BUG 38603, this issue was circumvented by stopping the MySQL
process, copying the file and then restarting the MySQL process. 

Unfortunately, such facilities are not available in the 5.0.  Other approaches
such as stopping the slave and issuing change master do not work because the relay
log file and index are not closed when a slave is stopped. So to fix the problem,
we simply don't run on windows the part of the test that was failing.
