## Changes in version 0.7.1.0 * Introduce convenience class `MonadPrim` and `MonadPrimBase`. * Add `PrimMonad` and `PrimBase` instances for `Lazy.ST` (GHC >= 8.2). thanks to Avi Dessauer (@Avi-D-coder) for this first contribution * Add `freezeByteArray` and `freezePrimArray`. * Add `compareByteArrays`. * Add `shrinkMutableByteArray`. * Add `Eq` instances for `MutableByteArray` and `MutablePrimArray`. by Andrew Martin * Add functions for manipulating pinned Prim Arrays by Andrew Martin * Add `copyPtrToMutableByteArray`. * Add `NFData` instances for `ByteArray`, `MutableByteArray`, `PrimArray` and `MutablePrimArray`. by Callan McGill * Add `shrinkSmallMutableArray`. * Add `clonePrimArray` and `cloneMutablePrimArray`. * Add `cloneMutableByteArray` and `cloneByteArray`. * Add `Prim` instances for `WordPtr` and `IntPtr`. * Add `NFData` instances for `Array` and `SmallArray`. by Callan McGill * Add `copyByteArrayToPtr` and `copyMutableByteArrayToPtr`. * Export `arrayFromList` and `arrayFromListN`. ## Changes in version 0.7.0.1 * Allow building with GHC 8.12. Thanks Ryan GL Scott for this and every compat patch over time. ## Changes in version 0.7.0.0 * Remove `Addr` data type, lifted code should use `Ptr a` now * Define `MonadFail` instances for `Array` and `SmallArray`. * Define `unsafeInterleave`. * Add a `Prim` instance for `StablePtr` * Remove `UnliftedArray` and related type classes * Add a lot more tests for `PrimArray`. * Added PrimMonad instance for CPS Writer and RWS monads from Transformers * Remove useless accidental laziness in `atomicModifyMutVar`, making it match `atomicModifyIORef`. The semantics should be the same. * lots of little documentation twiddles. ## Changes in version 0.6.4.1 * Add instances for the following newtypes from `base`: `Const`, `Identity`, `Down`, `Dual`, `Sum`, `Product`, `First`, `Last`, `Min`, `Max` * Add `base-orphans` dependency to test suite to accomodate older versions of GHC not having instances of `Show` and `Eq` for some of the above newtypes. ## 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`. * Add `Data.Primitive.MVar`, a replacement for `Control.Concurrent.MVar` that can run in any `PrimMonad` instead of just `IO`. It is not a full replacement. Notably, it's missing masking functions and support for adding finalizers. ## 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 * New in `Data.Primitive.ByteArray`: `copyByteArray`, `copyMutableByteArray`, `moveByteArray`, `fillByteArray` * Deprecated in `Data.Primitive.ByteArray`: `memcpyByteArray`, `memcpyByteArray'`, `memmoveByteArray`, `memsetByteArray` * New in `Data.Primitive.Array`: `copyArray`, `copyMutableByteArray` * New in `Data.Primitive.Addr`: `copyAddr`, `moveAddr` * Deprecated in `Data.Primitive.Addr`: `memcpyAddr`
