The bug is a regression introduced in 5.1 by the patch for bug28404.
Under some circumstances test_if_skip_sort_order() could leave some
data structures in an inconsistent state so that some parts of code
could assume the selected execution strategy for GROUP BY/DISTINCT as
a loose index scan (e.g. JOIN_TAB::is_using_loose_index_scan()), while
the actual strategy chosen was an ordered index scan, which led to
wrong data being returned.
Fixed test_if_skip_sort_order() so that when changing the type for a
join table, select->quick is reset not only for EXPLAIN, but for the
actual join execution as well, to not confuse code that depends on its
value to determine the chosen GROUP BY/DISTINCT strategy.
mysql-test/r/distinct.result:
Added a test case for bug #34928.
mysql-test/t/distinct.test:
Added a test case for bug #34928.
sql/sql_select.cc:
When changing the table's join type to JT_NEXT in
test_if_skip_sort_order(), also reset select->quick because other
code may depend on its value to determine the GROUP BY/DISTINCT
execution strategy.

plugin_load.test created lines in the warnings files and made
pushbuild cells yellow. Some pushbuild systems are configured
so that they don't build the ha_example plugin. Trying to load
them creates error messages in the error log. These were copied
to the warnings file.
Fixed by ignoring expected error messages for non-existent
ha_example.

When trying to get the requested amount of memory for the keybuffer,
the out of memory could be signaled if one of the tentative allocations
fail. Later the server would crash (debug assert) when trying to send
a ok packet with a error set.
The solution is only to signal the error if all tentative allocations
for the keybuffer fail.

by pushbuild.
mysql-test/suite/binlog/r/binlog_stm_ps.result:
Fixed binlog_stm_ps failure when binlog format is statement:
- this test case makes sence only if binlog format is statement,
thus execute it only in this mode;
- added a warning that insert ... select ... limit is not safe
to execute in statement mode.
mysql-test/suite/binlog/t/binlog_stm_ps.test:
Fixed binlog_stm_ps failure when binlog format is statement:

mysql-test/suite/rpl/t/rpl_optimize.test:
rpl_optimize test may be executed in various binlog format modes.
In statement mode delete ... limit issues a warning, in mixed and

Fixed a test case so it is still possible to execute it in all binlog
format modes by ignoring delete ... limit warnings.
mysql-test/suite/rpl/t/rpl_user_variables.test:
rpl_user_variables test may be executed in various binlog format modes.
In statement mode insert ... select ... limit issues a warning,
in mixed and row modes it does not.
Fixed a test case so it is still possible to execute it in all binlog
format modes by ignoring insert ... select ... limit warnings.
localhost/default port
When creating federated table that points to unspecified host or
localhost on unspecified port or port is 0, small memory leak occurs.
This happens because we make a copy of unix socket path, which is
never freed.
With this fix we do not make a copy of unix socket path, instead
share->socket points to MYSQL_UNIX_ADDR constant directly.
This fix is covered by a test case for BUG34788.
Affects 5.0 only.
mysql-test/t/federated.test:
A test case for BUG#35509.
sql/ha_federated.cc:
When creating federated table we call parse_url() to check if connect
string is correct. parse_url() may make a copy of unix socket path if
port is not specified or 0 and host is not specified or 'localhost'.
This copy is never freed.
As there is no need to make a copy of unix socket path, let
share->socket point to MYSQL_UNIX_ADDR directly.
for YEAR data type.
The problem was that for some unknown reason 0 was not allowed
as a default value for YEAR data type. That was coded before BK.
However the Manual does not say a word about such a limitation.
Also, it looks inconsistent with other data types.
The fix is to allow 0 as a default value.

correctly - crashes server !
Creating federated table with connect string containing empty
(zero-length) host name and port is evaluated as 0 (port is
incorrect, omitted or 0) crashes server.
This happens because federated calls strcmp() with NULL pointer.
Fixed by avoiding strcmp() call if hostname is set to NULL.
