Changelog of @hackage/store 0.4.0

ChangeLog

0.4.0

  • Breaking change in the encoding of Map / Set / IntMap / IntSet, to use ascending key order. Attempting to decode data written by prior versions of store (and vice versa) will almost always fail with a decent error message. If you're unlucky enough to have a collision in the data with a random Word32 magic number, then the error may not be so clear, or in extremely rare cases, successfully decode, yielding incorrect results. See #97 and #101.

  • Performance improvement of the 'Peek' monad, by introducing more strictness. This required a change to the internal API.

0.3.1

  • Fix to derivation of primitive vectors, only relevant when built with primitive-0.6.2.0 or later

  • Removes INLINE pragmas on the generic default methods. This dramatically improves compilation time on recent GHC versions. See #91.

  • Adds instance Contravariant Size

0.3

  • Uses store-core-0.3.*, which has support for alignment sensitive architectures.

  • Adds support for streaming decode from file descriptor, not supported on windows. As part of this addition, the API for "Data.Store.Streaming" has changed.

0.2.1.2

  • Fixes a bug that could could result in attempting to malloc a negative number of bytes when reading corrupted data.

0.2.1.1

  • Fixes a bug that could result in segfaults when reading corrupted data.

0.2.1.0

Release notes:

  • Adds experimental Data.Store.Version and deprecates Data.Store.TypeHash. The new functionality is similar to TypeHash, but there are much fewer false positives of hashes changing.

Other enhancements:

  • Now exports types related to generics

0.2.0.0

Release notes:

  • Core functionality split into store-core package

Breaking changes:

  • combineSize' renamed to combineSizeWith

  • Streaming support now prefixes each Message with a magic number, intended to detect mis-alignment of data frames. This is worth the overhead, because otherwise serialization errors could be more catastrophic - interpretting some bytes as a length tag and attempting to consume many bytes from the source.

Other enhancements:

  • weigh based allocations benchmark.

  • Addition of Array / UArray instances

  • Streaming support now has checks for over/undershooting buffer

Bug fixes:

0.1.0.0

  • First public release
