ChangeLog

0.7.0.0 2023-11-15

• Breaking:

  • (link) StorePath no longer carries storePathRoot field and we have a stand-alone StoreDir type instead to be used instead of FilePath when store root directory is needed as a context.

• Additional:

  • (link) NAR encoding and decoding now supports case-insensitive filesystems.
    • The "case hack" replicates the behavior of the use-case-hack option in Nix, which adds a suffix to conflicting filenames. This feature is enabled by default on macOS (darwin).
    • data NarOptions has been added to configure NAR encoding and decoding. The optUseCaseHack field can be used to enable or disable the case hack.
    • New streamNarIOWithOptions and runParserWithOptions functions have been added to System.Nix.Nar to support the new configurable options.

0.6.1.0 2023-01-02

• Fixed:

  • (link) (link) NAR serialization compatibility (symlinks, directory symlinks, UTF-8 handling)

0.6.0.0 2022-06-06

• Breaking:

  • (link) streamNarIO changes type and returns NarSource m
    • FilePath can turn to NarSource m using dumpPath
    • ByteString can turn to NarSource m using dumpString

0.5.0.0 2021-06-10

• Breaking:

  • System.Nix.Hash:
    • (link) Migration from packages cryptohash- -> cryptonite:
      • rm newtype Digest in favour of cryptonite: newtype Digest
      • rm data HashAlgorithm in favour of cryptonite: class HashAlgorithm
      • rm class ValidAlgo in favour of cryptonite: class HashAlgorithm.
      • class NamedAlgo removed hashSize in favour of cryptonite: class HashAlgorithm: hashDigestSize. Former became a subclass of the latter.
      • rm hash in favour of cryptonite: hash
      • rm hashLazy in favour of cryptonite: hashlazy
    • (link) Base encoding/decoding function for hashes (digests) changed (due to changes in type system & separation of specially truncated Nix Store hasing):
      • encode(InBase -> DigestWith)
      • decode(Base -> DigestWith)
  • (link) System.Nix.StorePath:
    • rm type StorePathHashAlgo = 'Truncated 20 'SHA256 in favour of StorePathHashPart & mkStorePathHashPart.
    • rm unStorePathName, please use GHC: coerce for StorePathName <-> Text, StorePathName data constructor is provided.
  • Internal modules now have export lists, if something, please contact.

• Additional:

  • (link) Support of GHC 9.0.

  • (link) System.Nix.StorePath:

    • exposed StorePathName data constructor to API.
    • added newtype StorePathHashPart = StorePathHashPart ByteString.
      • added builder mkStorePathHashPart :: ByteString -> StorePathHashPart

  • (link) System.Nix.Hash:

    • Nix store (which are specially truncated) hashes are now handled separately from other hashes:
      • add mkStorePathHash - a function to create a content into Nix storepath-style hash: mkStorePathHash :: HashAlgorithm a => ByteString -> ByteString but recommend to at once use mkStorePathHashPart.

0.4.3.0 2021-05-30

• Additional:
  • (link) System.Nix.ReadonlyStore: add a readonly computeStorePathForPath
  • (link) System.Nix.ReadonlyStore: computeStorePathForPath: force SHA256 as it's the only valid choice
  • (link): makeTextPath: order the references

0.4.2.0 2021-03-12

• Additional:

  • (link) Cabal now properly states tasty-discover as build-tool-depends.

  • (link) added explicit hie.yml cradle description for cabal to help Haskell Language Server to work with monorepo.

  • (link) rm vacuous Setup.hs, it was throwing-off HLS, and anyway file is vacuous and gets deprecated by Cabal itself.

  • (link) Nix dev env: removed GHC 8.6.5 support, afaik it is not even in Nixpkgs anymore.

  • (link) Test suite: fixed nar test for the envs without /proc (test suite now works on macOS).

0.4.1.0 2021-01-16

• Big clean-up of dependencies.

0.4.0.0 2020-12-30

• System.Nix.Hash no longer exports encodeBase16, decodeBase16 and their Base32 counterparts. These were replaced by encodeInBase and decodeBase functions accepting BaseEncoding data type #87
• Support base16-bytestring >= 1 #86 #100

0.3.0.0 -- 2020-11-29

• System.Nix.Nar changes API to support NAR format streaming:
  • buildNarIO :: FilePath -> Handle -> IO () - Create a NAR from a regular filesystem object, stream it out on the Handle
  • unpackNarIO :: Handle -> FilePath -> IO () - Recreate filesystem object from a NAR file accessed by the Handle
• StorePath type changed to simple variant without type level symbolic store path root.
• Added makeFixedOutputPath to System.Nix.ReadonlyStore
• Added decodeBase16 and decodeBase32 to System.Nix.Hash
• System.Nix.StorePath module now provides
  • storePathToFilePath and storePathToText helpers
  • storePathToNarInfo for converting paths to narinfo URLs
  • parsePath function
  • pathParser Attoparsec parser
• Added System.Nix.Build module
• Added System.Nix.Derivation module
• Removed System.Nix.Util module, moved to hnix-store-remote
• Added base64 and SHA512 hash support

0.2.0.0 -- 2020-03-12

Removed System.Nix.Store. We may reintroduce it later when multiple backends exist and we can tell what common effects they should share.

0.1.0.0 -- 2019-03-18

• First version.
