ACCEPTED BUT PARSED INCORRECTLY
When we are setting the value in a system variable,
We can set it like
set sys_var="Iden1.Iden2"; //1
set sys_var='Iden1.Iden2'; //2
set sys_var=Iden1.Iden2; //3
set sys_var=.ident1.ident2; //4
set sys_var=`Iden1.Iden2`; //5
While parsing, for case 1(when ANSI_QUOTES is enable) and 2,
we will take as string literal(we will make item of type Item_string).
for case 3 & 4, taken as Item_field, where Iden1 is a table name and
iden2 is a field name.
for case 5, again Item_field type, where iden1.iden2 is taken as
field name.
Now in case 1, when we are assigning some value to system variable
(which can take string or enumerate type data), we are setting only
field part.
This means only iden2 value will be set for system variable. This
result in wrong result.
Solution:
(for string type) We need to Document that we are not allowed to set
system variable which takes string as identifier, otherwise result
in unexpected behaviour.
(for enumerate type)
if we pass iden1.iden2, we will give an error ER_WRONG_TYPE_FOR_VAR
(Incorrect argument type to variable).
mysql-test/suite/sys_vars/t/general_log_file_basic.test:
Earlier we used to give ER_WRONG_VALUE_FOR_VAR error, but in the patch of
(Bug32748-Inconsistent handling of assignments to general_log_file/slow_query_log_file)
they quoted this line.But i am not able to find any relation of this with the changes of
patch. So i think We should give error in this case.

The maximum value for innodb_thread_sleep_delay is 4294967295 (32-bit) or
18446744073709551615 (64-bit) microseconds. This is way too big, since
the max value of innodb_thread_sleep_delay is limited by
innodb_adaptive_max_sleep_delay if that value is set to non-zero value
(its default is 150,000).
Solution
The maximum value of innodb_thread_sleep_delay should be the same as
the maximum value of innodb_adaptive_max_sleep_delay, which is 1000000.
Approved by Jimmy, rb#4429
- thread_pool_size command line option upper limit increased to 100 000
(same as for max_connections)
- thread_pool_size system variable upper limit is maximum of 128 or
the value given at command line
- thread groups are now allocated dynamically
Different limit for command line option and system variable was done to
avoid additional mutex for all_groups and threadpool_max_size.
Problem:
sys_vars.rpl_init_slave_func test was failing sporadically
on 5.5+.
Fix:
Added assert condition after wait for checks.
Recorded test and enabled it.
BUG#12535301- SYS_VARS.RPL_INIT_SLAVE_FUNC MISMATCHES IN DAILY-5.5
Problem:
sys_vars.rpl_init_slave_func test was not recorded after
the last edit. It was disabled on 5.1 after seeing failures
due to the above reason.
No old failures as this suite never ran with pb2 on 5.1
Fix:
Added assert condition after wait for checks.
Recorded test and enabled it.
-Added test and extra code to ensure we don't leave keyread on for a handler table.
-Create on disk temporary files always with long data pointers if SQL_SMALL_RESULT is not used. This ensures that we can handle temporary files bigger than 4G.

Change default for innodb_use_fallocate to FALSE, due to bugs in older Linux kernels (posix_fallocate() does not always guarantee that file size is like one specified)
This fixes that by default LOAD DATA INFILE will not generate the error:
"Multi-statement transaction required more than 'max_binlog_cache_size' bytes of storage..."
mysql-test/suite/sys_vars/r/max_binlog_cache_size_basic.result:

Updated test case
sql/sys_vars.cc:
Increase default value of max_binlog_cache_size and max_binlog_stmt_cache_size to ulonglong_max.
SUITE FOR 5.1
SYS_VARS suite is not enabled in MTR by default
run. Enabling it with this check-in.
mysql-test/suite/sys_vars/t/disabled.def:
Till the bugs are fixed, disabling the failed test scripts
buf_page_get_gen(): Do not attempt to decompress a compressed-only
page when mode == BUF_PEEK_IF_IN_POOL. This mode is only being used by
btr_search_drop_page_hash_when_freed(). There cannot be any adaptive
hash index pointing to a page that does not exist in uncompressed
format in the buffer pool.
innodb_buffer_pool_evict_update(): New function for debug builds, to handle
SET GLOBAL innodb_buffer_pool_evicted='uncompressed'
by evicting all uncompressed page frames of compressed tablespaces
from the buffer pool.

When a binlog is replayed into a server, e.g.:
$ mysqlbinlog binlog.000001 | mysql
it sets a pseudo slave mode on the client connection in order to server
be able to read binlog events, there is, a format description event is
needed to correctly read following events.
Also this pseudo slave mode applies to the current connection
replication rules that are needed to correctly apply binlog events.
If a binlog dump is sourced on a connection, this pseudo slave mode will
remains after it, what will apply unexpected rules from customer
perspective to following commands.
Added a new SET statement to binlog dump that will unset pseudo slave
mode at the end of dump file.
- no need to use --skip-ndb in collections files anymore, since long but
more clear logic after recent mtr.pl fixes. ndb tests are never run in MySQL Server
unless explicitly requested
- remove sys_vars.ndb_log_update_as_write_basic.test and sys_vars.ndb_log_updated_only_basic.result since MySQL Server does not have those
options.
- Only sys_vars.have_ndbcluster_basic left since MySQL Server has that variable hardcoded.
btr_lift_page_up() writes wrong page number (different by -1) for upper than father page.
But in almost all of the cases, the father page should be root page, no upper
pages. It is very rare path.
In addition the leaf page should not be lifted unless the father page is root.
Because the branch pages should not become the leaf pages.

NUMBERS
If a system variable was declared as deprecated without mention of an
alternative, the message would look funny, e.g. for @@delayed_insert_limit:
Warning 1287 '@@delayed_insert_limit' is deprecated and
will be removed in MySQL .
The message was meant to display the version number, but it's not
possible to give one when declaring a system variable.
The fix does two things:
1) The definition of the message
ER_WARN_DEPRECATED_SYNTAX_NO_REPLACEMENT is changed so that it does
not display a version number. I.e. in English the message now reads:
Warning 1287 The syntax '@@delayed_insert_limit' is deprecated and
will be removed in a future version.
2) The message ER_WARN_DEPRECATED_SYNTAX_WITH_VER is discontinued in
favor of ER_WARN_DEPRECATED_SYNTAX for system variables. This change
was already done in versions 5.6 and above as part of wl#5265. This
part is simply back-ported from the worklog.
two tests still fail:
main.innodb_icp and main.range_vs_index_merge_innodb
call records_in_range() with both range ends being open
(which triggers an assert)
