WL#8354 BACKPORT DIGEST IMPROVEMENTS TO MYSQL 5.6
(with the following commits) and related changes in sql/
as Item_func_spatial_mbr_rel needs nothing from Item_bool_func2.
- Renaming Item_func_spacial_rel (the class that implements precise spacial
relations) to Item_func_spatial_precise_rel
- Adding a new abstract class Item_func_spatial_rel as a common parent
for Item_func_spatial_precise_rel and Item_func_spatial_mbr_rel.
Step #3: Splitting the function check_equality() into a method in Item.
Implementing Item::check_equality() and Item_func_eq::check_equality().
Implement Item_func_eq::build_equal_items() in addition to
Item_func::build_equal_items() and moving the call for check_equality()
from Item_func::build_equal_items() to Item_func_eq::build_equal_items().
Step 2c:
After discussion with Igor, it appeared that Item_field and Item_ref
could not appear in this context in the old function build_equal_item_for_cond:
else if (cond->type() == Item::FUNC_ITEM ||
cond->real_item()->type() == Item::FIELD_ITEM)
The part of the condition checking for Item_field::FIELD_ITEM was a dead code.
- Moving implementation of Item_ident_or_func_or_sum::build_equal_items()
to Item_func::build_equal_items()
- Restoring deriving of Item_ident and Item_sum_or_func from Item_result_field.
Removing Item_ident_or_func_or_sum.
-LONGLONG_MIN is the undefined behavior in C.
longlong2decimal() used to do this:
int longlong2decimal(longlong from, decimal_t *to) {
if ((to->sign= from < 0))
return ull2dec(-from, to);
return ull2dec(from, to);
and later in ull2dec() (DIG_BASE is 1000000000):
static int ull2dec(ulonglong from, decimal_t *to) {
for (intg1=1; from >= DIG_BASE; intg1++, from/=DIG_BASE) {}
this breaks in gcc-5 at -O3. Here ull2dec is inlined into
longlong2decimal. And gcc-5 believes that 'from' in the
inlined ull2dec is always a positive integer (indeed, if it was
negative, then -from was used instead). So gcc-5 uses
*signed* comparison with DIG_BASE.
Fix: make a special case for LONGLONG_MIN, don't negate it
On EOF vio_read returns 0, it's not an error so the errno
is not reset. If the previous error was EINTR the client
will loop forever. See also man recv.
Tell OpenSSL to use MD5 even if FIPS prohibits it.
This is fine as long as we do not use MD5 for cryptographical
purposes (md5 is used internally for P_S message digests and for view
checksums)
1. After a period of wait (where last_master_timestamp=0)
do NOT restore the last_master_timestamp to the timestamp
of the last executed event (which would mean we've just
executed it, and we're that much behind the master).
2. Update last_master_timestamp before executing the event,
not after.
Take the approach from the this commit (but with a different test
case that actually makes sense):
