- Fix in CegoBTreeValue::valueFromSchema, introduced method
getReservedLength to return fixed value length for type fixed and
decimal. Since for decimal and fixed type just the dimension is
stored in CegoField::getLength, we must define a reserved area
for those types. This is done now with constant definition
RESERVED_BTREE_FLOATLEN in CegoDefs.h
- Improved ordersize calculation in CegoOrderSpace:insertTuple. Now
the following formula is used :
int s = sizeof(fv);
if ( fv.getLength() > STATICFIELDBUF )
s += fv.getLength();
orderEntryLen += s;
The catches the base memory usage for the instance but also the
dynamic allocated part

- Fix in CegoXMLSpace::setTSSortAreaSize, changed type from int to
unsigned long long, otherwise overflow may occur for large sort
area size configurations
- Performance optimization done in CegoOrderSpace. Instead of storing
the CegoField list for the result tuple in CegoOrderNode, just the
values are stored there. The order cursor now gets the schema with
the constructor and build the CegoField List in the getFirst /
getNext methods. This seems a huge amount of heap space, which is
dynamically allocated during the sorting procedure ( sortareasize
parameter ).
Especially for large ordering result sets this saves significantly
memory and improves performance.

- Fix in CegoPredDesc::decode, loop variable i for IN/NOTIN case
was not initialized
- Fix in CegoAction::execCheckCreate, check contraints are checked
for contained subselects. subselects are ( still ) not supported
since the CegoCheckOject::decode method can not provide a valid
tablemanager instance ( it is called from CegoObjectManager )

databases/cegobridge: update 1.2.1 -> 1.3.0
cego:
- Fix in CegoSelect::clone, pUnionSelect was not cloned, which might
lead to seg faults
- Introduced predicate clause for select .. in ( expr, expr, ... ),
e.g. select * from t1 where a in ( 1, 2, 3 ); This was still not
implemented but is part of standard SQL.
cegobridge:
- Adaptions made for modified cego-2.38.0 API with extended
CegoDatabaseFormatter::formatPred method ( exprList was added for
new introduced select in ( expr list ) predicate )

<ChangeLog>
Upgrade urgency HIGH: Potentially critical bugs fixed.
AOF flush on SHUTDOWN did not cared to really write the AOF buffers
(not in the kernel but in the Redis process memory) to disk before exiting.
Calling SHUTDOWN during traffic resulted into not every operation to be
persisted on disk.
</ChangeLog>
Notable changes:
- mcrypt module was removed
- sodium module was added
- sybase_ct artifacts removed
Also many PECL ports will not work with this version
since some files got renamed.
