This is because in Linux RAND_MAX is 2**31-1 and we used int32_t to
hold random number from random() and got each bytes. This means that
highest bit is always unset. In little endian system, every 4n-th (n
>=0) byte has highest bit is unset. To fix this, we just use lower 2
bytes of random().
MinGW32 lacks random(), so we use CryptGenRandom() as a replacement.
In the implementation, SimpleRandomizer::getRandomNumber() returns the
random number in range [0, INT32_MAX]. Thus,
simpleRandomizer::getMaxRandomNumber() returns INT32_MAX.
Removed SharedHandle::isNull(). Instead we added operator* and
operator unspecified_bool_type. Removed use of WeakHandle and
replaced with raw pointer.
Moved implementation to SimpleRandomizer.cc from
SimpleRandomizer.h.
Added return value of getpid() to argument of srand() to achieve
more
randomized value.
* src/SimpleRandomizer.cc
* src/SimpleRandomizer.h
Rewritten SharedHandle. Now copy constructor taking raw pointer
has
keyword explicit and SharedHandle's default constructor
initializes
its internal obj to null, old implementation initializes it
using
obj's default constructor.
To assign null, write SharedHandle<T> x(...); x.reset();
TODO: test/SharedHandleTest.cc needs more tests.
* src/SharedHandle.h
To fix the bug that causes crash on Max OS X:
* src/SimpleRandomizer.h
(getInstance): Create new instance if the static variable is
null.
* src/SimpleRandomizer.cc
(randomizer): Initialized to 0.
* src/BitfieldManFactory.h
(getNewFactory): Removed the call to setRandomizer().
To fix the miscalculation of the range of checksum:
* src/BitfieldMan.h
(isBitSetOffsetRange): New function.
* src/BitfieldMan.cc
(isBitSetOffsetRange): New function.
* src/SegmentMan.cc
(tryChunkChecksumValidation): Use
BitfieldMan::isBitSetOffsetRange().
Use bitfield->getBlockLength() instead of segment.segmentLength.
