This was done after discussions with Igor, Sanja and Bar.
The main reason for removing the deprication was to ensure that MariaDB
is always backward compatible whenever possible.
Other things:
- Added statistics counters, mainly for the feedback plugin.
- INTO OUTFILE
- INTO variable
- If INTO is using the old syntax (end of query)
There are two fill_record() functions (lines 8343 and 8618). First one
is used when there are some explicit values, the second one is used
for all implicit values. First one does update_default_fields(), the
second one did not. Added update_default_fields() call to the implicit
version of fill_record().
Field::make_new_field() resets invisible property (needed for "CREATE
.. SELECT" f.ex.). Recover invisible property in
Delayed_insert::get_local_table() (unireg_check works by the same
principle).
For a unique key if all the keyparts are NOT NULL or the predicates involving
the keyparts is NULL rejecting, then we can use EQ_REF access instead of ref
access with the unique key
insert into table with TIMESTAMP INVISIBLE
Problem:- The segfault occurs because value is null but since timestamp field
is VISIBLE it expects a value , and it tries to call value->save_in_field(..
Timestamp field should not be visible this is the problem.
Solution:- While we clone field for record0_field we don't honor the field
_visibility , this patch changes that.
