Changelog of @hackage/streamly-core 0.2.2

Changelog

0.2.2 (Jan 2024)

  • Add fixities infixr 5 for cons and consM functions.
  • Fix a bug in Array Eq instance when the type is a sum type with differently sized constructors.
  • lpackArraysChunksOf, compact, writeChunksWith, putChunksWith now take the buffer size in number of array elements instead of bytes.

0.2.1 (Dec 2023)

  • Make the serialization of the unit constructor deterministic.
  • Expose pinnedSerialize & deserialize via Streamly.Data.Array.

0.2.0 (Nov 2023)

See 0.1.0-0.2.0 API Changelog for a full list of API changes in this release. Only a few significant changes are mentioned here.

Breaking Changes

  • ParserK in Streamly.Data.ParserK is not implicitly specialized to arrays anymore. To adapt to the new code, change ParserK a m b to ParserK (Array a) m b where the Array type comes from Streamly.Data.Array. This change also affected the signatures of parseChunks and parseBreakChunks.
  • Changed the signature of 'Streamly.Data.Stream.handle' to make the exception handler monadic.
  • Behavior change: Exceptions are now rethrown promptly in bracketIO.

Enhancements

  • Serialization: Added a Streamly.Data.MutByteArray module with a Serialize type class for fast binary serialization. The Data.Array module supplies the serialize and deserialize operations for arrays.
  • Unpinned Arrays: Unboxed arrays are now created unpinned by default, they were created pinned earlier. During IO operations, unpinned arrays are automatically copied to pinned memory. When arrays are directly passed to IO operations programmers can choose to create them pinned to avoid a copy. To create pinned arrays, use the internal APIs with the pinned* prefix.
  • StreamK now supports native exception handling routines (handle, bracketIO). Earlier we had to convert it to the Stream type for exception handling.

Deprecations

See 0.1.0-0.2.0 API Changelog for a full list of deprecations.

Internal API Changes

  • Fold constructor has changed, added a final field to support finalization and cleanup of a chain of folds. The extract field is now used only for mapping the fold internal state to fold result for scanning purposes. If your fold does not require cleanup you can just use your existing extract function as final as well to adapt to this change.
  • Many low level internal modules have been removed, they are entirely exported from higher level internal modules. If you were importing any of the missing low level modules then import the higher level modules instead.
  • Internal module changes:
    • Streamly.Internal.Serialize.FromBytes -> Streamly.Internal.Data.Binary.Parser
    • Streamly.Internal.Serialize.ToBytes -> Streamly.Internal.Data.Binary.Stream
    • Streamly.Internal.Data.Unbox is now exported via Streamly.Internal.Data.Serialize
    • Streamly.Internal.Data.IORef.Unboxed is now exported via Streamly.Internal.Data.Serialize

0.1.0 (March 2023)

Also see streamly-core-0.1.0 API Changelog or https://hackage.haskell.org/package/streamly-core-0.1.0/docs/docs/ApiChangelogs/0.1.0.txt

streamly package is split into two packages, (1) streamly-core that has only GHC boot library depdendecies, and (2) streamly that contains higher level operations (including concurrent ones) with additional dependencies.

  • Moved the following modules from streamly package to the streamly-core package:
    • Streamly.Console.Stdio
    • Streamly.Data.Fold
    • Streamly.Data.Unfold
    • Streamly.FileSystem.Handle
    • Streamly.Unicode.Stream
  • Added the following new modules:
    • Streamly.Data.Array
    • Streamly.Data.Array.Generic
    • Streamly.Data.MutArray
    • Streamly.Data.MutArray.Generic
    • Streamly.Data.Parser
    • Streamly.Data.ParserK
    • Streamly.Data.Stream
    • Streamly.Data.StreamK
    • Streamly.FileSystem.Dir
    • Streamly.FileSystem.File
    • Streamly.Unicode.Parser
    • Streamly.Unicode.String
