The bug is repeatable with latest(1.0.1) InnoDB plugin on Linux, Win,
If MySQL is compiled with valgrind there are errors about
using of uninitialized variable(orig_table).
The fix is to set field->orig_table correct value.

Post-pushbuild fix.

- Windows does not have 'socket' system variable.
- Compiler warning in sql/slave.cc

mysql-test/r/variables.result:
  Bug#28234 - global/session scope - documentation vs implementation
  Updated test result.
mysql-test/t/variables.test:
  Bug#28234 - global/session scope - documentation vs implementation
  Removed test for 'socket' variable. Windows doesn't have it.
sql/slave.cc:
  Bug#28234 - global/session scope - documentation vs implementation
  Changed type of constant to avoid a compiler warning.

symlink.test failed when run in an environment that has mysql-test/var
symlinked to elsewhere, e.g. a memory file system. This is the case
when running mysql-test-run --mem.

In this case the server does not detect that the directory specified
with a DATA/INDEX DIRECTORY clause is within its data home directory.
This problem was reported as Bug#39277 (Creation of table with data
and/or index files in data home directory succeeds). It was decided
that it will not be fixed in 5.1. Hence, the current behavior is
accepted for 5.1. It will be fixed in 6.0 though.

Fixed the test case so that it works in both environments. 1. When no
symbolic link is involved, the server notices that the data/index
directory is in its data hone directory and rejects the CREATE/ALTER
TABLE statement. 2. When the data home directory is symlinked, it
does not notice the problem and executes the statement sucessfully.


mysql-test/r/symlink.result:
  Bug#41002 - symlink.test fails on symlinked datadir
  Updated test result.
mysql-test/t/symlink.test:
  Bug#41002 - symlink.test fails on symlinked datadir
  Adjusted the test case to the accepted behavior.
  It needs to accept success and failure of some statements.

Problem: in 5.0 'check table for upgrade' doesn't detect
incompatible collation changes made in 5.0.48.

Fix: backport #39585 fix to 5.0

Altering how MTR checks global variable status to exclude timestamp
Changed SQL statements to update style.

Problem was usage of read_range_first with an empty key.

Solution was to not to give a key if it was empty.

ONLY_FULL_GROUP_BY

The check for non-aggregated columns in queries with aggregate function, but without
GROUP BY was treating all the parts of the query as if they are in the SELECT list.
Fixed by ignoring the non-aggregated fields in the WHERE clause.

mysql-test/r/func_group.result:
  Bug #39656: test case
mysql-test/t/func_group.test:
  Bug #39656: test case
sql/sql_select.cc:
  Bug #39656: ignore the new non-aggregated column refs in a WHERE
  by saving the state so far and then adding only the new values of the other
  parts of the bitmask.

Several system variables did not behave like system variables should do.
When trying to SET them or use them in SELECT, they were reported as
"unknown system variable". But they appeared in SHOW VARIABLES.

This has been fixed by removing the "fixed_vars" array of variables
and integrating the variables into the normal system variables chain.
All of these variables do now behave as read-only global-only
variables. Trying to SET them tells they are read-only, trying to
SELECT the session value tells they are global only. Selecting the
global value works. It delivers the same value as SHOW VARIABLES.
