Zero fill is a field attribute only. So we can't always
propagate constants for zerofill fields : the values and
expression results don't have that flag.
Fixed by converting the const value to a string and
using that in const propagation when the context allows it.
Disable const propagation for fields with ZEROFILL flag in
all the other cases.

from storage engine
Federated may crash a server, return wrong result set, return
"ERROR 1030 (HY000): Got error 1430 from storage engine" message
when local (engine=federated) table has a key against nullable
column.
The problem was wrong implementation of function that creates
WHERE clause for remote query from key.
mysql-test/r/federated.result:
A test case for BUG#33946.
mysql-test/t/federated.test:
A test case for BUG#33946.
sql/ha_federated.cc:
Fixed that federated adds " IS NULL " condition to a remote query,
whereas "IS NOT NULL" requested by original query.
Fixed that federated didn't check for end of key buffer, didn't
setup key buffer pointer and remaining lenght of key buffer,
didn't add " AND " between conditions in case original query
has IS [NOT] NULL condition against nullable column.
Fixed that federated wrongly shifts key buffer pointer by extra
one byte when key part may be null (was: store_length + 1,
now: store_length).
for wildcard values.
The server ignored escape character before wildcards during
the calculation of priority values for sorting of a privilege
list. (Actually the server counted an escape character as an
ordinary wildcard like % or _). I.e. the table name template
with a wildcard character like 'tbl_1' had higher priority in
a privilege list than concrete table name without wildcards
like 'tbl\_1', and some privileges of 'tbl\_1' was hidden
by privileges for 'tbl_1'.
The get_sort function has been modified to ignore escaped
wildcards as usual.

sql/sql_acl.cc:
Fixed bug#31194.
The server used the wild_prefix escape character (usually \-character)
like % and _ wildcards in the get_sort function for sorting weights
calculation.
The get_sort function has been modified to ignore escaped wildcards
and alone escapes like in the wild_case_compare function.
type conversion.
Instead of copying of whole character string from a temporary
buffer, the server copied a short-living pointer to that string
into a long-living structure. That has been fixed.

functional source item.
or trigger crashes server
Under some circumstances a combination of VIEWs, subselects with outer
references and PS/SP/triggers could lead to use of uninitialized memory
and server crash as a result.
Fixed by changing the code in Item_field::fix_fields() so that in cases
when the field is a VIEW reference, we first check whether the field
is also an outer reference, and mark it appropriately before returning.

sql/field.cc:
Fixed bug#15409.
The Field_set::store(longlong nr,...) method incompletely
calculates a bit mask for the comparison with a given number:
if that number is greater than 0x7F00 0000 0000 0000 (LONGLONG_MAX),
it uses zero bit mask instead of 0xFFFF FFFF FFFF FFFF (ULONGLONG_MAX).
Incomplete expression has been replaced with a set_bits macro call.
The unsignedness of large integer user variables was not being
properly preserved when feeded to prepared statements. This was
happening because the unsigned flags wasn't being updated when
converting the user variable is converted to a parameter.
The solution is to copy the unsigned flag when converting the
user variable to a parameter and take the unsigned flag into
account when converting the integer to a string.

The bug was that handler::clone/handler::ha_open() call caused allocation of
cloned_copy->ref on the handler->table->mem_root. The allocated memory could not
be reclaimed until the table is flushed, so it was possible to exhaust memory by
repeatedly running index_merge queries without doing table flushes.
The fix:
- make handler::clone() allocate new_handler->ref on the passed mem_root
- make handler::ha_open() not allocate this->ref if it has already been allocated
There is no testcase as it is not possible to check small leaks from testsuite.
sql/handler.cc:

However, my_innodb_autoextend_increment and
my_innodb_commit_concurrency are declared as GET_LONG.
Call stack is:
sys_var_long_ptr_global::update()

Server handles truncation for assignment of too-long values
into CHAR/VARCHAR/TEXT columns in a different ways when the
truncated characters are spaces:
1. CHAR(N) columns silently ignore end-space truncation;
2. TEXT columns post a truncation warning/error in the
non-strict/strict mode.
3. VARCHAR columns always post a truncation note in
any mode.
Space truncation processing has been synchronised over
CHAR/VARCHAR/TEXT columns: current behavior of VARCHAR
columns has been propagated as standard.
Binary-encoded string/BLOB columns are not affected.

The report_data_too_long function was replaced with the
Field_longstr::report_if_important_data method.
The Field_string::store and the Field_blob::store
methods was synchronized with the Field_varstring::store
method.
Changes:
1. to CHAR(N): posting of space truncation note has been added
in both (strict and non-strict) modes;
2. to BLOBs: a check for space truncation has been added,
a warning in the non-strict mode and an error message in
the strict mode have been replaced with a truncation note.
Similar parts of Field_string::store, Field_blob::store and
Field_varstring::store have been moved to the
Field_longstr::report_if_important_data method.
sql/field.h:
Fixed bug#30059.
The Field_longstr::report_if_important_data method has been declared.
to leave
The artifact was caused by
a flaw in concurrent accessing the slave's io thd by
the io itself and a handling show slave status thread.
Namely, show_master_info did not acquire mi->run_lock mutex that is
specified for mi->io_thd member.
Fixed with deploying the mutex locking and unlocking. The mutex is kept
short time and without interleaving with mi->data_lock mutex.
Todo: to report and fix an issue with
sys_var_slave_skip_counter::{methods}
seem to acquire incorrectly
active_mi->rli.run_lock
instead of the specified
active_mi->rli.data_lock
A test case is difficult to compose, so rpl_packet should continue serving
as the indicator.

on table creates
The problem was in incompatible syntax for key definition in CREATE
TABLE.
5.0 supports only the following syntax for key definition (see "CREATE
TABLE syntax" in the manual):
{INDEX|KEY} [index_name] [index_type] (index_col_name,...)
While 5.1 parser supports the above syntax, the "preferred" syntax was
changed to:
{INDEX|KEY} [index_name] (index_col_name,...) [index_type]
The above syntax is used in 5.1 for the SHOW CREATE TABLE output, which
led to dumps generated by 5.1 being incompatible with 5.0.
Fixed by changing the parser in 5.0 to support both 5.0 and 5.1 syntax
for key definition.

Simple subselects are pulled into upper selects. This operation substitutes the
pulled subselect for the first item from the select list of the subselect.
If an alias is defined for a subselect it is inherited by the replacement item.
As this is done after fix_fields phase this alias isn't showed if the
replacement item is a stored function. This happens because the Item_func_sp::make_field
function makes send field from its result_field and ignores the defined alias.
Now when an alias is defined the Item_func_sp::make_field function sets it for
the returned field.

Here is the scenario that causes the failure.(by Mats)
1. The to-be corrupt log event (let's call it X), is split into two
packets B and C on the network level (net_write_buff()). The parts
are X = (x',x''). The part x' ends up in packet B and part x''
ends up in packet C. Prior to the corrupt event X, the event Y has
been written successfully, but has been split into two packets as
well, which we call (y',y'').
2. The master sends packet A = (y'',x') to the slave, increases the
packet sequence number, the slave receives the packet, but fails
to reply before the master gets a timeout.
3. Since the master got a timeout, it reports failure, and aborts
sending the binary log by exiting mysql_binlog_send(). However, it
leaves the buffer intact, still holding y'' (but not x', since the
write_pos is not increased).
4. After exiting mysql_binlog_send(), the master does a
disconnection of the client thread, which involves sending an
error message e to the client (i.e., the slave).
5. In this case, net_write_buff() is used again, but this time the
old contents of the packet is used so that the new packet is
D = (y'',e). Note that this will use a new packet sequence number,
since the packet number was increased in step 2.
6. The slave receives the tail y'' of the Y log event, concatenates
this with x' (which it already received), and writes the event
(x',y'') it to the relay log since it hasn't noticed anything is
amiss.
7. It then tries to read more bytes, which is either e (if the length
given for X just happened to match the length given for Y, or just
plain garbage because the slave is out of sync with what is
actually sent.
8. After a while, the SQL thread tries to execute the event (x',y''),
which is very likely to be just nonsense.
The problem can be fixed by not resetting net->error after the call of
mysql_binlog_send, so the error message will not be sent and the connection
will be closed.
sql/sql_parse.cc:
Do not reset net->error, if net->error == 2, we should not try to use the connection again
Two disjuncts containing equalities of the form key=const1 and key=const2 can
be merged into one if const1 is equal to const2. To check it the common
collation of the constants were used rather than the collation of the field key.
For example when the default collation of the constants was cases insensitive
while the collation of the field was case sensitive, then two or-ed equality
predicates key='b' and key='B' incorrectly were merged into one f='b'. As a
result ref access was used instead of range access and wrong result sets were
returned in many cases.
Fixed the problem by comparing constant in the or-ed predicate with collation of
the key field.
