762df2d05c Additional fix for bug#31455 (rpl decoder)
- Implementing --base64-format=decode-rows, to display
  SQL-alike decoded row events without their BINLOG statements.
- Adding --base64-format=decode-rows into tests when
  calling mysqlbinlog to avoid non-deterministic results
- Removing resetting of last_table_id in "RESET MASTER",
  which appeared to be dangerous.

  update m_part_spec.start_part and m_last_part properly.
  This makes the inited state to be correct.

de73b72954 Bug#38291 memory corruption and server crash with view/sp/function
Send_field.org_col_name has broken value on secondary execution.
It happens when result field is created from the field which belongs to view

bbb45c158f Bug#35807 - INSTALL PLUGIN replicates row-based, but not stmt-based
INSTALL PLUGIN and UNINSTALL PLUGIN worked with statement-based and
mixed-mode replication only, but not with row-based replication.

There is no statement-based replication of these statements.
But there was row-based replication of the inserts and deletes
to and from the mysql.plugin table.

The fix is to suppress binlogging during insert and delete to
and from the mysql.plugin table.

02f305516f Bug#35981: ALTER EVENT causes the server to change the PRESERVE option.
If [NOT] PRESERVE was not given, parser always defaulted to NOT
PRESERVE, making it impossible for the "not given = no change"
rule to work in ALTER EVENT. Leaving out the PRESERVE-clause
defaults to NOT PRESERVE on CREATE now, and to "no change" in
ALTER.

mysql-test/r/events_2.result:
  show that giving no PRESERVE-clause to ALTER EVENT
  results in no change. show that giving no PRESERVE-clause
  to CREATE EVENT defaults to NOT PRESERVE as per the docs.
  Show specifically that this is also handled correctly when
  trying to ALTER EVENTs into the past.
mysql-test/t/events_2.test:
  show that giving no PRESERVE-clause to ALTER EVENT
  results in no change. show that giving no PRESERVE-clause
  to CREATE EVENT defaults to NOT PRESERVE as per the docs.
  Show specifically that this is also handled correctly when
  trying to ALTER EVENTs into the past.
sql/event_db_repository.cc:
  If ALTER EVENT was given no PRESERVE-clause (meaning "no change"),
  we don't know the previous PRESERVE-setting by the time we check
  the parse-data. If ALTER EVENT was given dates that are in the past,
  we don't know how to react, lacking the PRESERVE-setting. Heal this
  by running the check later when we have actually read the previous
  EVENT-data.
sql/event_parse_data.cc:
  Change default for ON COMPLETION to indicate, "not specified."
  Also defer throwing errors when ALTER EVENT is given dates in
  the past but not PRESERVE-clause until we know the previous
  PRESERVE-value.
sql/event_parse_data.h:
  Add third state for ON COMPLETION [NOT] PRESERVE (preserve,
  don't, not specified).
  
  Make check_dates() public so we can defer this check until
  deeper in the callstack where we have all the required data.
sql/sql_yacc.yy:
  If CREATE EVENT is not given ON COMPLETION [NOT] PRESERVE,
  we default to NOT, as per the docs.

35c8b4c5e7 Bug#38272: timestamps fields incorrectly defaulted on \
update accross partitions.
      
It's not Innodb-specific bug.
ha_partition::update_row() didn't set
table->timestamp_field_type= TIMESTAMP_NO_AUTO_SET when
orig_timestamp_type == TIMESTAMP_AUTO_SET_ON_INSERT.

So that a partition sets the timestamp field when a record
is moved to a different partition.

Fixed by doing '= TIMESTAMP_NO_AUTO_SET' unconditionally.
Also ha_partition::write_row() is fixed in same way as now
Field_timestamp::set() is called twice in SET_ON_INSERT case.

(Chad queues this patch on demand by Trudy/Davi.)

02cd785691 Bug#38560: valgrind warnings on PB due to query profiling
Fix for a valgrind warning due to a jump on a uninitialized
variable. The problem was that the sql profile preparation
function wasn't being called for all possible code paths
of query execution.

The solution is to ensure that query profiling is always
started before dispatch_command function is called and to
explicitly call the profile preparation function on bootstrap.



sql/sql_parse.cc:
  Finish query profiling properly when executing bootstrap commands.
  Add query profiling to execute_init_command as it calls dispatch_command.

67a3d9e4d0 Fix for bug#37337: Function returns different results
Problem: REGEXP in functions/PSs may return wrong results
due to improper initialization.

Fix: initialize required REGEXP params.


sql/item_cmpfunc.cc:
  Fix for bug#37337: Function returns different results
  
  prev_regexp is used in the Item_func_regex::regcomp()
  to store previous regex and to avoid re-initialization 
  if given the same pattern.
  Shoud be deleted in the Item_func_regex::cleanup() where we
  clean up the regexp structure.

b789b4f33c Bug#38195: Incorrect handling of aggregate functions when loose index scan is
used causes server crash.

When the loose index scan access method is used values of aggregated functions
are precomputed by it. Aggregation of such functions shouldn't be performed
in this case and functions should be treated as normal ones.
The create_tmp_table function wasn't taking this into account and this led to
a crash if a query has MIN/MAX aggregate functions and employs temporary table
and loose index scan.
Now the JOIN::exec and the create_tmp_table functions treat MIN/MAX aggregate
functions as normal ones when the loose index scan is used.

7ea370d2a2 Bug#38296 (low memory crash with many conditions in a query)
This fix is for 5.1 only : back porting the 6.0 patch manually

The parser code in sql/sql_yacc.yy needs to be more robust to out of
memory conditions, so that when parsing a query fails due to OOM,
the thread gracefully returns an error.

Before this fix, a new/alloc returning NULL could:
- cause a crash, if dereferencing the NULL pointer,
- produce a corrupted parsed tree, containing NULL nodes,
- alter the semantic of a query, by silently dropping token values or nodes

With this fix:
- C++ constructors are *not* executed with a NULL "this" pointer
when operator new fails.
This is achieved by declaring "operator new" with a "throw ()" clause,
so that a failed new gracefully returns NULL on OOM conditions.

- calls to new/alloc are tested for a NULL result,

- The thread diagnostic area is set to an error status when OOM occurs.
This ensures that a request failing in the server properly returns an
ER_OUT_OF_RESOURCES error to the client.

- OOM conditions cause the parser to stop immediately (MYSQL_YYABORT).
This prevents causing further crashes when using a partially built parsed
tree in further rules in the parser.

No test scripts are provided, since automating OOM failures is not
instrumented in the server.
Tested under the debugger, to verify that an error in alloc_root cause the
thread to returns gracefully all the way to the client application, with
an ER_OUT_OF_RESOURCES error.
