Changelog of @hackage/servant-client-core 0.20.1

The latest version of this document is on GitHub. Changelog for servant package contains significant entries for all core packages.

Package versions follow the Package Versioning Policy: in A.B.C, bumps to either A or B represent major versions.

0.20

  • Escape special chars in QueryParams. #1584 #1597

    Escape special chars in QueryParam (:@&=+$) in servant-client. Note that this mean binary data will not work as is, and so reverts the functionality in #1432.

  • Handle Cookies correctly for RunStreamingClient #1605 #1606

    Makes performWithStreamingRequest take into consideration the CookieJar, which it previously didn't.

  • Fix the handling of multiple headers with the same name. #1666

    servant-client no longer concatenates the values of response headers with the same name. This fixes an issue with parsing multiple Set-Cookie headers.

0.19

Significant changes

  • Drop support for GHC < 8.6.
  • Support GHC 9.0 (GHC 9.2 should work as well, but isn't fully tested yet).
  • Support Aeson 2 (#1475), which fixes a DOS vulnerability related to hash collisions.
  • Add NamedRoutes combinator, making support for records first-class in Servant (#1388).
  • Add custom type errors for partially applied combinators (#1289, #1486).
  • servant-client / servant-client-core / servant-http-streams: Fix erroneous behavior, where only 2XX status codes would be considered successful, irrelevant of the status parameter specified by the verb combinator. (#1469)
  • servant-client / servant-client-core: Fix Show instance for Servant.Client.Core.Request.
  • servant-client / servant-client-core: Allow passing arbitrary binary data in Query parameters. (#1432).

Other changes

  • Various version bumps.

0.18.3

Significant changes

  • Add response header support to UVerb (#1420)

Other changes

  • Support GHC-9.0.1.
  • Bump bytestring, hspec, base64-bytestring and QuickCheck dependencies.

0.18.2

Significant changes

  • Support Fragment combinator.

0.18.1

Significant changes

  • Union verbs

Other changes

  • Bump "tested-with" ghc versions
  • Loosen bound on base16-bytestring

0.18

Significant changes

  • Support for ghc8.8 (#1318, #1326, #1327)

0.17

Significant changes

  • Add NoContentVerb #1028 #1219 #1228

    The NoContent API endpoints should now use NoContentVerb combinator. The API type changes are usually of the kind

    - :<|> PostNoContent '[JSON] NoContent
    + :<|> PostNoContent
    

    i.e. one doesn't need to specify the content-type anymore. There is no content.

  • Capture can be Lenient #1155 #1156

    You can specify a lenient capture as

    :<|> "capture-lenient"  :> Capture' '[Lenient] "foo" Int :> GET
    

    which will make the capture always succeed. Handlers will be of the type Either String CapturedType, where Left err represents the possible parse failure.

Other changes

  • servant-client servant-client-core servant-http-streams Fix Verb with headers checking content type differently #1200 #1204

    For Verbs with response Headers, the implementation didn't check for the content-type of the response. Now it does.

  • servant-client servant-http-streams HasClient instance for Stream with Headers #1170 #1197

  • servant-client Redact the authorization header in Show and exceptions #1238

0.16

  • Rename ServantError to ClientError, ServantErr to ServerError #1131

  • servant-client-core Rearrange modules. No more Internal modules, whole API is versioned. #1130

  • servant-client-core RequestBody is now

    = RequestBodyLBS LBS.ByteString
    | RequestBodyBS BS.ByteString
    | RequestBodySource (SourceIO LBS.ByteString)
    

    i.e. no more replicates http-clients API. #1117

  • servant-client-core Keep structured exceptions in ConnectionError constructor of ClientError #1115

    -| ConnectionError Text
    +| ConnectionError SomeException
    
  • servant-client-core Preserve failing request in FailureResponse constructor of ClientError #1114

    -FailureResponse Response
    +-- | The server returned an error response including the
    +-- failing request. 'requestPath' includes the 'BaseUrl' and the
    +-- path of the request.
    +FailureResponse (RequestF () (BaseUrl, BS.ByteString)) Response
    
  • servant-client Fix (implement) StreamBody instance #1110

  • servant-client Update CookieJar with intermediate request/responses (redirects) #1104

0.15

  • Streaming refactoring. #991 #1076 #1077

    The streaming functionality (Servant.API.Stream) is refactored to use servant's own SourceIO type (see Servant.Types.SourceT documentation), which replaces both StreamGenerator and ResultStream types.

    New conversion type-classes are ToSourceIO and FromSourceIO (replacing ToStreamGenerator and BuildFromStream). There are instances for conduit, pipes and machines in new packages: servant-conduit servant-pipes and servant-machines respectively.

    Writing new framing strategies is simpler. Check existing strategies for examples.

    This change shouldn't affect you, if you don't use streaming endpoints.

  • servant-client Separate streaming client. #1066

    We now have two http-client based clients, in Servant.Client and Servant.Client.Streaming.

    Their API is the same, except for

    • Servant.Client cannot request Stream endpoints.
    • Servant.Client is run by direct runClientM :: ClientM a -> ClientEnv -> IO (Either ServantError a)
    • Servant.Client.Streaming can request Stream endpoints.
    • Servant.Client.Streaming is used by CPSised withClientM :: ClientM a -> ClientEnv -> (Either ServantError a -> IO b) -> IO b

    To access Stream endpoints use Servant.Client.Streaming with withClientM; otherwise you can continue using Servant.Client with runClientM. You can use both too, ClientEnv and BaseUrl types are same for both.

    Note: Servant.Client.Streaming doesn't stream non-Stream endpoints. Requesting ordinary Verb endpoints (e.g. Get) will block until the whole response is received.

    There is Servant.Client.Streaming.runClientM function, but it has restricted type. NFData a constraint prevents using it with SourceT, Conduit etc. response types.

    runClientM :: NFData a => ClientM a -> ClientEnv -> IO (Either ServantError a)
    

    This change shouldn't affect you, if you don't use streaming endpoints.

  • servant-client-core Related to the previous: streamingResponse is removed from RunClient. We have a new type-class:

    class RunClient m =>  RunStreamingClient m where
        withStreamingRequest :: Request -> (StreamingResponse -> IO a) ->  m a
    
  • Drop support for GHC older than 8.0 #1008 #1009

  • servant-client-core Add NFData (GenResponse a) and NFData ServantError instances. #1076

  • servant-client-core Add aeson and Lift BaseUrl instances #1037

0.14.1

  • Merge in servant-generic (by Patrick Chilton) into servant (Servant.API.Generic), servant-client-code (Servant.Client.Generic) and servant-server (Servant.Server.Generic).

0.14

  • Stream takes a status code argument

    -Stream method        framing ctype a
    +Stream method status framing ctype a
    

    (#966 #972)

  • ToStreamGenerator definition changed, so it's possible to write an instance for conduits.

    -class ToStreamGenerator f a where
    -   toStreamGenerator :: f a -> StreamGenerator a
    +class ToStreamGenerator a b | a -> b where
    +   toStreamGenerator :: a -> StreamGenerator b
    

    (#959)

  • Added NoFraming streaming strategy (#959)

  • servant-client-core Free Client implementation. Useful for testing HasClient instances. (#920)

  • servant-client-core Add hoistClient to HasClient. Just like hoistServer allows us to change the monad in which request handlers of a web application live, we also have hoistClient for changing the monad in which client functions live. Read tutorial section for more information. (#936)

    iF you have own combinators, you'll need to define a new method of HasClient class, for example:

    type Client m (MyCombinator :> api) = MyValue :> Client m api
    hoistClientMonad pm _ nt cl = hoistClientMonad pm (Proxy :: Proxy api) nt . cl
    

0.13.0.1

0.13

  • Streaming endpoint support. (#836)
  • servant Add Servant.API.Modifiers (#873)

0.12

  • First version. Factored out of servant-client all the functionality that was independent of the http-client backend.
