mysql.procs_priv table itself does not get replicated.
Inserting routine privilege record into mysql.procs_priv table
is triggered by creating function/procedure statements
according to current user's privileges.
Because the current user of SQL thread has GLOBAL_ACL,
which doesn't need any check mysql.procs_priv privilege
when create/alter/execute routines.
Corresponding GLOBAL_ACL privilege user
doesn't insert routine privilege record into
mysql.procs_priv when creating a routine.

Fixed by switching the current user of SQL thread to definer user if
the definer user exists on slave.
That populates procs_priv, otherwise to keep the SQL thread
user and procs_priv remains unchanged.


mysql-test/suite/rpl/r/rpl_do_grant.result:
  Test case result for routine privilege when definer user exist or not on slave
mysql-test/suite/rpl/t/rpl_do_grant.test:
  Test case result for routine privilege when definer user exist or not on slave
sql/sql_parse.cc:
  Switch current user of SQL thread to definer user if the definer user
  existes on slave when checking whether the routine privilege is
  needed to insert mysql.procs_priv table or not.

Any statement reading corrupt archive data file
(CHECK/REPAIR/SELECT/UPDATE/DELETE) may cause assertion
failure in debug builds. This assertion has been removed
and an error is returned instead.

Also fixed that CHECK/REPAIR returns vague error message
when it mets corruption in archive data file. This is
fixed by returning proper error code.

mysql-test/r/archive.result:
  A test case for BUG#32880
mysql-test/std_data/bug32880.ARN:
  corrupted archive table to test check and repair table operation
mysql-test/std_data/bug32880.ARZ:
  corrupted archive table to test check and repair table operation
mysql-test/std_data/bug32880.frm:
  corrupted archive table to test check and repair table operation
mysql-test/t/archive.test:
  A test case for BUG#32880
storage/archive/ha_archive.cc:
  Fixed unpack_row() to return the error instead of throwing assertion 
  and also fixed repair() to throw better error when repair table
  operation fails on corrupted archive table

The reason for the error is incorrectly specified link dependencies
for mysql_embedded, mysqltest_embedded and mysql_client_test_embedded
in CMakeLists.txt (ADD_DEPENDENCIES should be TARGET_LINK_LIBRARIES)


libmysqld/CMakeLists.txt:
  changed library type for libmysqld to SHARED instead of
  MODULE. MODULE in CMake notation is a shared library that 
  is used only in dlopen/dlsym/LoadLibrary scenarios.
  Hence it was impossible to use TARGET_LINK_LIBRARIES with
  a MODULE.
libmysqld/examples/CMakeLists.txt:
  Use TARGET_LINK_LIBRARIES (instead of previously incorrectly 
  used ADD_DEPENDENCIES) to specify link dependency from libmysqld

One call to my_error_unregister_all() would free pointers, but leave one
pointer to just-freed memory still assigned.  That's the bug.  Subsequent
calls of this function would try to follow pointers into deallocated, 
garbage memory and almost certainly SEGV.

Now, after freeing a linked list, unset the initial pointer.

become negative

- merged the fix to 5.1
- extended to cover I_S.PROCESSLIST.TIME
- Changed the column type of I_S.PROCESSLIST.TIME from LOGNLONG
  UNSIGNED
  to LONG (to match the SHOW PROCESSLIST type)
- Added a test case

"Release_lock("hello")" is now also successful when delivering NULL, replaced two sleeps by wait_condition. The last two "sleep 1" have not been replaced as all tried wait conditions leaded to nondeterministic results, especially to succeeding concurrent updates. To replace the sleeps there should be some time planned (or internal knowledge of the server may help).
 

sql/sql_select.cc:
  the if() separate arguments checks are slightly faster.

Re-recording of .result files for additional tests that use this include file.

	my_print_defaults

Now use basedir to set an unset ledir and to find the location of
my_print_defaults .

If a sys-var has a base and a block-size>1, and then a
user-supplied value >= minimum ended up below minimum
thanks to block-size alignment, we threw a warning.
This meant for instance that when getting, then setting
the minimum, we'd see a warning. This was needlessly
confusing. (updated patch)

Replaced a call to load_defaults() in sql_plugin.cc with 
its thread-safe version.

select where .. (col=col and col=col) or ... (false expression)

Problem: optimizer didn't take into account a singular case 
when we eliminated all the predicates at the AND level of WHERE.
That may lead to wrong results.

Fix: replace (a=a AND a=a...) with TRUE if we eliminated all the
predicates.


mysql-test/r/select.result:
  Fix for bug #42957: no results from 
  select where .. (col=col and col=col) or ... (false expression)
    - test result.
mysql-test/t/select.test:
  Fix for bug #42957: no results from 
  select where .. (col=col and col=col) or ... (false expression)
    - test case.
sql/sql_select.cc:
  Fix for bug #42957: no results from 
  select where .. (col=col and col=col) or ... (false expression)
    - replacing equality predicates by multiple equality items check
  if we eliminate all the predicates at the AND level and 
  replace them with TRUE if so.

Revised patch incorporating cleaner test code brought up during review.
Removed the use of grep and accomplished same actions via SQL / use of the server.

Runs as before on *nix systems and now runs on Windows without Cygwin as well.
