0.18
----
### Significant changes
- Support for ghc8.8 (#1318, #1326, #1327)
2020-01-23 12:43:19 +01:00
0.17
----
### Significant changes
- Add NoContentVerb [#1028](https://github.com/haskell-servant/servant/issues/1028) [#1219](https://github.com/haskell-servant/servant/pull/1219) [#1228](https://github.com/haskell-servant/servant/pull/1228)
The `NoContent` API endpoints should now use `NoContentVerb` combinator.
The API type changes are usually of the kind
```diff
- :<|> 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](https://github.com/haskell-servant/servant/issues/1155) [#1156](https://github.com/haskell-servant/servant/pull/1156)
You can specify a lenient capture as
```haskell
:<|> "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](https://github.com/haskell-servant/servant/issues/1200) [#1204](https://github.com/haskell-servant/servant/pull/1204)
For `Verb`s 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](https://github.com/haskell-servant/servant/issues/1170) [#1197](https://github.com/haskell-servant/servant/pull/1197)
- *servant-client* Redact the authorization header in Show and exceptions [#1238](https://github.com/haskell-servant/servant/pull/1238)
0.16
----
- Rename `ServantError` to `ClientError`, `ServantErr` to `ServerError`
[#1131](https://github.com/haskell-servant/servant/pull/1131)
- *servant-client-core* Rearrange modules. No more `Internal` modules, whole
API is versioned.
[#1130](https://github.com/haskell-servant/servant/pull/1130)
- *servant-client-core* `RequestBody` is now
```haskell
= RequestBodyLBS LBS.ByteString
| RequestBodyBS BS.ByteString
| RequestBodySource (SourceIO LBS.ByteString)
```
i.e. no more replicates `http-client`s API.
[#1117](https://github.com/haskell-servant/servant/pull/1117)
- *servant-client-core* Keep structured exceptions in `ConnectionError`
constructor of `ClientError`
[#1115](https://github.com/haskell-servant/servant/pull/1115)
```diff
-| ConnectionError Text
+| ConnectionError SomeException
```
- *servant-client-core* Preserve failing request in `FailureResponse`
constructor of `ClientError`
[#1114](https://github.com/haskell-servant/servant/pull/1114)
```diff
-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](https://github.com/haskell-servant/servant/pull/1110)
- *servant-client* Update CookieJar with intermediate request/responses (redirects)
[#1104](https://github.com/haskell-servant/servant/pull/1104)
0.15
----
- Streaming refactoring.
[#991](https://github.com/haskell-servant/servant/pull/991)
[#1076](https://github.com/haskell-servant/servant/pull/1076)
[#1077](https://github.com/haskell-servant/servant/pull/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](https://hackage.haskell.org/package/servant-conduit)
[servant-pipes](https://hackage.haskell.org/package/servant-pipes) and
[servant-machines](https://hackage.haskell.org/package/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](https://github.com/haskell-servant/servant/pull/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.
```haskell
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:
```haskell
class RunClient m => RunStreamingClient m where
withStreamingRequest :: Request -> (StreamingResponse -> IO a) -> m a
```
- Drop support for GHC older than 8.0
[#1008](https://github.com/haskell-servant/servant/pull/1008)
[#1009](https://github.com/haskell-servant/servant/pull/1009)
- *servant-client-core* Add `NFData (GenResponse a)` and `NFData ServantError` instances.
[#1076](https://github.com/haskell-servant/servant/pull/1076)
- *servant-client-core* Add `aeson` and `Lift BaseUrl` instances
[#1037](https://github.com/haskell-servant/servant/pull/1037)
2018-07-04 21:59:43 +02:00
0.14.1
------
- Merge in `servant-generic` (by [Patrick Chilton](https://github.com/chpatrick))
into `servant` (`Servant.API.Generic`),
`servant-client-code` (`Servant.Client.Generic`)
and `servant-server` (`Servant.Server.Generic`).

0.14
----
2018-06-18 16:12:35 +02:00
- `Stream` takes a status code argument
```diff
-Stream method framing ctype a
+Stream method status framing ctype a
```
([#966](https://github.com/haskell-servant/servant/pull/966)
[#972](https://github.com/haskell-servant/servant/pull/972))
- `ToStreamGenerator` definition changed, so it's possible to write an instance
for conduits.
```diff
-class ToStreamGenerator f a where
- toStreamGenerator :: f a -> StreamGenerator a
+class ToStreamGenerator a b | a -> b where
+ toStreamGenerator :: a -> StreamGenerator b
```
([#959](https://github.com/haskell-servant/servant/pull/959))
- Added `NoFraming` streaming strategy
([#959](https://github.com/haskell-servant/servant/pull/959))
- *servant-client-core* Free `Client` implementation.
Useful for testing `HasClient` instances.
([#920](https://github.com/haskell-servant/servant/pull/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
2018-06-18 16:12:35 +02:00
in which *client functions* live.
Read [tutorial section for more information](https://docs.servant.dev/en/release-0.14/tutorial/Client.html#changing-the-monad-the-client-functions-live-in).
2018-04-09 13:57:31 +02:00
([#936](https://github.com/haskell-servant/servant/pull/936))
2018-06-18 16:12:35 +02:00
iF you have own combinators, you'll need to define a new method of
`HasClient` class, for example:
```haskell
type Client m (MyCombinator :> api) = MyValue :> Client m api
hoistClientMonad pm _ nt cl = hoistClientMonad pm (Proxy :: Proxy api) nt . cl
```

2018-02-08 11:29:16 +01:00
0.13
----
- Streaming endpoint support.
([#836](https://github.com/haskell-servant/servant/pull/836))
- *servant* Add `Servant.API.Modifiers`
([#873](https://github.com/haskell-servant/servant/pull/873))
0.12
----
- First version. Factored out of `servant-client` all the functionality that was
independent of the `http-client` backend.
