- This is a regession introduced by fix for BUG#951937
- The problem was that there were scenarios where check_simple_equality() would create an
Item_equal object but would not call item_equal->set_context_field() on it.
- The fix was to add the missing calls.
Analysis:
-------------------------------
According to the Manual
(http://dev.mysql.com/doc/refman/5.1/en/identifier-case-sensitivity.html):
"Column, index, stored routine, and event names are not case sensitive on any
platform, nor are column aliases."
In other words, 'lower_case_table_names' does not affect the behaviour of
those identifiers.
On the other hand, trigger names are case sensitive on some platforms,
and case insensitive on others. 'lower_case_table_names' does not affect
the behaviour of trigger names either.
The bug was that SHOW statements did case sensitive comparison
for stored procedure / stored function / event names.
Fix:
Modified the code so that comparison in case insensitive for routines
and events for "SHOW" operation.
- The problem was with execution strategy for cases where FirstMatch's inner tables
were interleaved with outer-uncorrelated tables.
- I was unable to find any cases where such join orders would be practically useful,
so fixed it by disabling them.

- Fix equality propagation to work with SJM nests and OR clauses (full descirption of problem and
solution in the comment in the patch)
(The second commit with post-review fixes)
- The problem was that
= we've picked a LooseScan that used full index scan (tab->type==JT_ALL) on certain index.
= there was also a quick select (tab->quick!=NULL), that used other indexes.
= some old code assumes that (tab->type==JT_ALL && tab->quick) -> means that the
quick select should be used, which is not true.
Fixed by discarding the quick select as soon as we know we're using LooseScan
without using the quick select.
suppress these harmless but confusing warnings.
fix the program name (MY_INIT) in mysqldump
client/mysqldump.c:
for backward compatibility, prefix mysqldump error messages with "mysqldump", not with the full path of the executable
If the first component of a ref key happened to be a constant appeared
after constant row substitution then no store_key element should be
created for such a component. Yet create_ref_for_key() erroneously could
create such an element that caused construction of invalid ref keys and
wrong results for some joins.
Problem:
Field_set::val_str in case of an empty SET value
returned a String with str_length==0 and Ptr==0,
which is not expected by some pieces of the code.
Fix:
Returning an empty string with str_length==0 and Ptr=="",
like Field_enum does.
Make the slave options --replicate-* dynamic variables so that these
options can be changed dynamically while the server is running,
which enables users to modify replication filtering rules without
having to stop and restart the server.
This is accomplished by just requiring that the slave threads are
stopped when these options are set dynamically. Since filtering
rules are only used by the SQL slave thread, setting them while the
thread is not running avoids the need for locking.
Remove Aria state history for drop/rename

Ensure that we don't use file->trn if THD_TRN is 0. (This means that implict_commit() has been called and the trn object is not ours anymore)

- The problem was that convert_subq_to_jtbm() attached the semi-join
TABLE_LIST object into the wrong list: they used to attach it to the
end of parent_lex->leaf_tables.head()->next_local->...->next_local.
This was apparently inccorect, as one can construct an example where
JTBM nest is attached to a table that is inside some mergeable VIEW, which
breaks (causes crash) for name resolution on the subsequent statement
re-execution.
- Solution: Attach to the "right" list. The "wording" was copied from
st_select_lex::handle_derived.
- do not attempt loading federatedx dynamically - does not work on Windows embedded
- race condition in rpl_start_stop_slave
- fix exclusion rule to catch warning in partition test
The test case must insert all the records using a single transaction. Otherwise the test
case takes more than 15 minutes and will time out in pb2 and mtr.
AND SAVEPOINT.
The bug was introduced by the patch for bug#11766752. This patch sets too
strong condition on XA state for SAVEPOINT statement that disallows its
execution during XA transaction. But since the statement SAVEPOINT doesn't
imply implicit commit we can allow its handling during XA transaction.
The patch explicitly check for transaction state against states XA_NOTR
and XA_ACTIVE for which the handling of statement SAVEPOINT for XA
transaction is allowed.
mysql-test/t/xa.test:
Testcase was adjusted for bug#13737343. Now SAVEPOINT is allowed for XA
transactions in ACTIVE state.
The table contains one time value: '00:00:32'
This value is converted to timestamp by a subquery.
In convert_constant_item we call (*item)->is_null()
which triggers execution of the Item_singlerow_subselect subquery,
and the string "0000-00-00 00:00:32" is cached
by Item_cache_datetime.
We continue execution and call update_null_value, which calls val_int()
on the cached item, which converts the time value to ((longlong) 32)
Then we continue to do (*item)->save_in_field()
which ends up in Item_cache_datetime::val_str() which fails,
since (32 < 101) in number_to_datetime, and val_str() returns NULL.
Item_singlerow_subselect::val_str isnt prepared for this:
if exec() succeeds, and return !null_value, then val_str()
*must* succeed.
Solution: refuse to cache strings like "0000-00-00 00:00:32"
in Item_cache_datetime::cache_value, and return NULL instead.
This is similar to the solution for
Bug#11766860 - 60085: CRASH IN ITEM::SAVE_IN_FIELD() WITH TIME DATA TYPE
This patch is for 5.5 only.
The issue is not present after WL#946, since a time value
will be converted to a proper timestamp, with the current date
rather than "0000-00-00"
mysql-test/r/subselect.result:
New test case.
mysql-test/t/subselect.test:
New test case.
sql/item.cc:
Verify proper date format before caching timestamps.
sql/item_timefunc.cc:
Use named constant for readability.
We are trying to sort a lot of text/blob fields,
so the buffer is indeed too small.
Memory available = thd->variables.sortbuff_size = 262144
min_sort_memory = param.sort_length*MERGEBUFF2 = 292245
So the decision to abort the query is correct.
filesort() calls my_error(), the error is reported.
But, since we have DELETE IGNORE ... the error is converted to a warning by
THD::raise_condition
filesort currently expects an error to be recorded in the THD diagnostics
area.
If we lift this restriction (remove the assert) we end up in the familiar
void Protocol::end_statement()
default:
DBUG_ASSERT(0);
The solution seems to be to call my_error(ME_FATALERROR) in filesort,
so that the error is propagated as an error rather than a warning.
mysql-test/r/filesort_debug.result:
New test case.
mysql-test/t/filesort_debug.test:
New test case.
ENOUGH - CONCAT() HACKS. ALSO WRONG
ERROR MESSAGE WHILE TRYING TO CREATE
A VIEW ON A NON EXISTING DATABASE
PROBLEM:
The first part of the problem is concluded as not a
bug, as 'concat' is not a reserved word and it is
completely valid to create a view with the name
'concat'.
The second issue is, while trying to create a view on
a non existing database, we are not giving a proper error
message.
FIX:
We have added a check for the database existence while
trying to create a view. This check would give an error
as 'unknown database' when the database does not exist.
This patch is a backport of the patch for Bug#13601606
mysql-test/r/view.result:
Added test case result of Bug#12626844
mysql-test/t/view.test:
Added test case for Bug#12626844
sql/sql_view.cc:
Added a check for database existence in mysql_create_view
