Problem: creating an rb-tree key we store length (2 bytes) before the actual data for

6d54b5771b Bug #30286 spatial index cause corruption and server crash!
As the result of DOUBLE claculations can be bigger
than DBL_MAX constant we use in code, we shouldn't use this constatn
as a biggest possible value.
Particularly the rtree_pick_key function set 'min_area= DBL_MAX' relying
that any rtree_area_increase result will be less so we return valid
key. Though in rtree_area_increase function we calculate the area
of the rectangle, so the result can be 'inf' if the rectangle is
huge enough, which is bigger than DBL_MAX.

Code of the rtree_pick_key modified so we always return a valid key.

bf8a85aa56 Bug #29309 Incorrect "Seconds_Behind_Master" value in SHOW SLAVE STATUS after FLUSH LOGS
Report claims that Seconds_behind_master behaves unexpectedly. 

Code analysis shows that there is an evident flaw in that treating of FormatDescription event is wrong
so  that after FLUSH LOGS on slave the Seconds_behind_master's calculation slips and incorrect
value can be reported to SHOW SLAVE STATUS. 
Even worse is that the gap between the correct and incorrect deltas grows with time.

Fixed with prohibiting changes to rpl->last_master_timestamp by artifical events (any kind of).
suggestion as comments is added how to fight with lack of info on the slave side by means of
new heartbeat feature coming.

The test can not be done ealily fully determistic.


sql/log_event.cc:
  changing timestamp is affirmed only by non-artificial events. Artifical FD won't change it anymore.
  The simulation code is off unless server is started with the args from the opt-file.
  The simulation code assumes that it will execute specific schedule generated by rpl_replication_delay.test.
sql/slave.cc:
  Comments are changed to announce a new possibility to cope with
  Seconds_behind_master jumping due to EOF special treatment (reset of the timestamp)
mysql-test/suite/manual/r/rpl_replication_delay.result:
  result are not deterministic though there are comments saying the most probable expected
  value for Seconds_behind_master
mysql-test/suite/manual/t/rpl_replication_delay-slave.opt:
  bug emulation
mysql-test/suite/manual/t/rpl_replication_delay.test:
  specic test for bug#29309. It's hard to make it reliable as it deals with timestamps.
  (a way to automate the test like this is to have I_S table for show slave status' fields)
  
  A possible way to check results is to run
  grep -i 'show\|seconds' < suite/manual/r/rpl_replication_delay.reject and to get the lines like these:
  
  show slave status /* Second_behind reports 0 */;;
  Seconds_Behind_Master   0
  show slave status /* bug emulated: reports slave threads starting time about 3*3 not 3 secs */;;
  Seconds_Behind_Master   9
  show slave status /* reports the correct diff with master query time about 3+3 secs */;;
  Seconds_Behind_Master   6
  
  Due to time discreteness of time the reported numbers may slightly vary. That's why the test is not reliable.

4f14c13a1c Fix for BUG#31035: select from function, group by result crasher.
This actually, fix for the patch for bug-27354. The problem with
the patch was that Item_func_sp::used_tables() was updated, but
Item_func_sp::const_item() was not. So, for Item_func_sp, we had
the following inconsistency:
  - used_tables() returned RAND_TABLE, which means that the item
    can produce "random" results;
  - but const_item() returned TRUE, which means that the item is
    a constant one.

The fix is to change Item_func_sp::const_item() behaviour: it must
return TRUE (an item is a constant one) only if a stored function
is deterministic and each of its arguments (if any) is a constant
item.

549cbcd547 Restore creation of test databases and the anonymous user which
were accidentally removed during a previous rototill of this

While it can be argued we should strive to provide a 'secure by

documented in the manual as the default, so defer changes that
improve security out of the box to a co-ordinated effort later
on.
  
For now, make a note about the test databases and anonymous user
in mysql_install_db and recommend that mysql_secure_installation
be ran for users wishing to remove these defaults.

1a4df8a24d Bug#31095: Unexpected NULL constant caused server crash.
The Item_func_rollup_const class is used for wrapping constants to avoid
wrong result for ROLLUP queries with DISTINCT and a constant in the select
list. This class is also used to wrap up a NULL constant but its null_value
wasn't set accordingly. This led to a server crash.

Now the null_value of an object of the Item_func_rollup_const class is set
by its fix_length_and_dec member function.
