## Changes in version 0.6.4.0
|
||
|
|
|
||
|
|
* Introduce `Data.Primitive.PrimArray`, which offers types and function
|
||
|
|
for dealing with a `ByteArray` tagged with a phantom type variable for
|
||
|
|
tracking the element type.
|
||
|
|
|
||
|
|
* Implement `isByteArrayPinned` and `isMutableByteArrayPinned`.
|
||
|
|
|
||
|
|
* Add `Eq1`, `Ord1`, `Show1`, and `Read1` instances for `Array` and
|
||
|
|
`SmallArray`.
|
||
|
|
|
||
|
|
* Improve the test suite. This includes having property tests for
|
||
|
|
typeclasses from `base` such as `Eq`, `Ord`, `Functor`, `Applicative`,
|
||
|
|
`Monad`, `IsList`, `Monoid`, `Foldable`, and `Traversable`.
|
||
|
|
|
||
|
|
* Fix the broken `IsList` instance for `ByteArray`. The old definition
|
||
|
|
would allocate a byte array of the correct size and then leave the
|
||
|
|
memory unitialized instead of writing the list elements to it.
|
||
|
|
|
||
|
|
* Fix the broken `Functor` instance for `Array`. The old definition
|
||
|
|
would allocate an array of the correct size with thunks for erroring
|
||
|
|
installed at every index. It failed to replace these thunks with
|
||
|
|
the result of the function applied to the elements of the argument array.
|
||
|
|
|
||
|
|
* Fix the broken `Applicative` instances of `Array` and `SmallArray`.
|
||
|
|
The old implementation of `<*>` for `Array` failed to initialize
|
||
|
|
some elements but correctly initialized others in the resulting
|
||
|
|
`Array`. It is unclear what the old behavior of `<*>` was for
|
||
|
|
`SmallArray`, but it was incorrect.
|
||
|
|
|
||
|
|
* Fix the broken `Monad` instances for `Array` and `SmallArray`.
|
||
|
|
|
||
|
|
* Fix the implementation of `foldl1` in the `Foldable` instances for
|
||
|
|
`Array` and `SmallArray`. In both cases, the old implementation
|
||
|
|
simply returned the first element of the array and made no use of
|
||
|
|
the other elements in the array.
|
||
|
|
|
||
|
|
* Fix the implementation of `mconcat` in the `Monoid` instance for
|
||
|
|
`SmallArray`.
|
||
|
|
|
||
|
|
* Implement `Data.Primitive.Ptr`, implementations of `Ptr` functions
|
||
|
|
that require a `Prim` constraint instead of a `Storable` constraint.
|
||
|
|
|
||
|
|
|
||
|
|
* Add `PrimUnlifted` instances for `TVar` and `MVar`.
|
||
|
|
|
||
|
|
* Use `compareByteArrays#` for the `Eq` and `Ord` instances of
|
||
|
|
`ByteArray` when building with GHC 8.4 and newer.
|
||
|
|
|
||
|
|
* Add `Prim` instances for lots of types in `Foreign.C.Types` and
|
||
|
|
`System.Posix.Types`.
|
||
|
|
|
||
|
|
* Reexport `Data.Primitive.SmallArray` and `Data.Primitive.UnliftedArray`
|
||
|
|
from `Data.Primitive`.
|
||
|
|
|
||
|
|
* Add fold functions and map function to `Data.Primitive.UnliftedArray`.
|
||
|
|
Add typeclass instances for `IsList`, `Ord`, and `Show`.
|
||
|
|
|
||
|
|
* Add `defaultSetByteArray#` and `defaultSetOffAddr#` to
|
||
|
|
`Data.Primitive.Types`.
|
||
|
|
|
||
|
|
## Changes in version 0.6.3.0
|
||
|
|
|
||
|
|
* Add `PrimMonad` instances for `ContT`, `AccumT`, and `SelectT` from
|
||
|
|
`transformers`
|
||
|
|
|
||
|
|
* Add `Eq`, `Ord`, `Show`, and `IsList` instances for `ByteArray`
|
||
|
|
|
||
|
|
* Add `Semigroup` instances for `Array` and `SmallArray`. This allows
|
||
|
|
`primitive` to build on GHC 8.4 and later.
|
||
|
|
|
||
|
|
## Changes in version 0.6.2.0
|
||
|
|
|
||
|
|
* Drop support for GHCs before 7.4
|
||
|
|
|
||
|
|
* `SmallArray` support
|
||
|
|
|
||
|
|
* `ArrayArray#` based support for more efficient arrays of unlifted pointer types
|
||
|
|
|
||
|
|
* Make `Array` and the like instances of various classes for convenient use
|
||
|
|
|
||
|
|
* Add `Prim` instances for Ptr and FunPtr
|
||
|
|
|
||
|
|
* Add `ioToPrim`, `stToPrim` and unsafe counterparts for situations that would
|
||
|
|
otherwise require type ascriptions on `primToPrim`
|
||
|
|
|
||
|
|
* Add `evalPrim`
|
||
|
|
|
||
|
|
* Add `PrimBase` instance for `IdentityT`
|
||
|
|
|
||
|
|
## Changes in version 0.6.1.0
|
||
|
|
|
||
|
|
* Use more appropriate types in internal memset functions, which prevents
|
||
|
|
overflows/segfaults on 64-bit systems.
|
||
|
|
|
||
|
|
* Fixed a warning on GHC 7.10
|
||
|
|
|
||
|
|
* Worked around a -dcore-lint bug in GHC 7.6/7.7
|
||
|
|
|
||
|
|
## Changes in version 0.6
|
||
|
|
|
||
|
|
* Split PrimMonad into two classes to allow automatic lifting of primitive
|
||
|
|
operations into monad transformers. The `internal` operation has moved to the
|
||
|
|
`PrimBase` class.
|
||
|
|
|
||
|
|
* Fixed the test suite on older GHCs
|
||
|
|
|
||
|
|
## Changes in version 0.5.4.0
|
||
|
|
|
||
|
|
* Changed primitive_ to work around an oddity with GHC's code generation
|
||
|
|
on certain versions that led to side effects not happening when used
|
||
|
|
in conjunction with certain very unsafe IO performers.
|
||
|
|
|
||
|
|
* Allow primitive to build on GHC 7.9
|
||
|
|
|
||
|
|
## Changes in version 0.5.3.0
|
||
|
|
|
||
|
|
* Implement `cloneArray` and `cloneMutableArray` primitives
|
||
|
|
(with fall-back implementations for GHCs prior to version 7.2.1)
|
||
|
|
|
||
|
|
## Changes in version 0.5.2.1
|
||
|
|
|
||
|
|
* Add strict variants of `MutVar` modification functions
|
||
|
|
`atomicModifyMutVar'` and `modifyMutVar'`
|
||
|
|
|
||
|
|
* Fix compilation on Solaris 10 with GNU C 3.4.3
|
||
|
|
|
||
|
|
## Changes in version 0.5.1.0
|
||
|
|
|
||
|
|
* Add support for GHC 7.7's new primitive `Bool` representation
|
||
|
|
|
||
|
|
## Changes in version 0.5.0.1
|
||
|
|
|
||
|
|
* Disable array copying primitives for GHC 7.6.* and earlier
|
||
|
|
|
||
|
|
## Changes in version 0.5
|
||
|
|
|
||
|
|
* New in `Data.Primitive.MutVar`: `atomicModifyMutVar`
|
||
|
|
|
||
|
|
* Efficient block fill operations: `setByteArray`, `setAddr`
|
||
|
|
|
||
|
|
## Changes in version 0.4.1
|
||
|
|
|
||
|
|
* New module `Data.Primitive.MutVar`
|
||
|
|
|
||
|
|
## Changes in version 0.4.0.1
|
||
|
|
|
||
|
|
* Critical bug fix in `fillByteArray`
|
||
|
|
|
||
|
|
## Changes in version 0.4
|
||
|
|
|
||
|
|
* Support for GHC 7.2 array copying primitives
|
||
|
|
|
||
|
|

|
||
|
|
`copyMutableByteArray`, `moveByteArray`, `fillByteArray`
