* Routes ending in a `CaptureAll` now get an empty list instead of
[""] when they have a trailing slash.
* WARNING: I think this will break the expectation that a rooted
capture all will produce [""] for `//`. That is, previously `// =>
[""]`, but I think `// => []`. I will make some tests to check
and see what is going on with this.
* This fails two of the tests. We should probably add a catch all
at the end that captures anything not matches by the Symbols for
the preceding branches `arms` and `legs`.
* When using `CaptureAll` from the root "/" and empty path becomes
an empty list. when using it from a branch though an empty path,
ie. a trailing separator, becomes `mempty` for the type. Where is
this happening? I think this is definitely happening before
`parseUrlpieces` gets run, so it happens in the machinery for
Delayed and DelayedIO. I am still looking for the code that
produces the `txts` argument for the `captureD` lambda created in
the `HasServer` instance for `CaptureAll`.
Currently there is no way for Servant users to customize formatting of
error messages that arise when combinators can't parse URL or request
body, apart from reimplementing those combinators for themselves or
using middlewares.
This commit adds a possibility to specify custom error formatters
through Context.
Fixes#685
- Introduce SourceT, which is simple variant of "correct `ListT`".
There are another variants possible (like in `streaming`),
but I'm not sure there's much real difference.
- Introduce `Codensity`. There's a flag if people don't want to depend
on `kan-extensions`.
- `StreamGenerator` and `ResultStream` are both `SourceT`.
`Stream` combinator in `servant-client` uses `Codensity` for CPS.
- Add servant-machines, servant-conduit, servant-pipes
- Add streaming cookbook: just code, no explanations.
- Add a script to run streaming 'benchmarks'
In case that a sub-server doesn't support the content-type specified
in the request invoke `delayedFail` instead of `delayedFailFatal` in
order to give the chance to other sub-servers to handle the request.
- WIP: pending http-api-data release
- TODO: remove MIN_VERSION_http_types
- There have been 3 major releases of http-types:
- 0.10 change name of variable
- 0.11 lowercase escaped URIs
- 0.12 uppercase escaped URIs
- It's easier for us to support only latest, migration from 0.9/0.10 to 0.12
is trivial for the downstream. 0.11 may cause semantic (non-type-error) breakage somewhere.
Also allow lens-4.16, remove MIN_VERSION_http_types conditionals, and
update `stack.yaml`
Changes Header, ReqBody and QueryParam to take a modifier list.
Resolves https://github.com/haskell-servant/servant/issues/856
ResponseHeader story turns to be somewhat ugly, but it can be made
elegant when https://github.com/haskell-servant/servant/issues/841 is
implemnted, then we can omit HList aka Header Heterogenous List
implementation.
- servant-server changes:
Writing server side intepretations is quite simple using
`unfoldRequestArgument`, which makes Header and QueryParam look quite
the same.
`ReqBody` cannot be easily made optional with current design (what that
would mean: No Content-Type Header?), so that dimensions isn't used
there.
- Add HasLink for all the rest ComprehensiveAPI combinators
- Add 'tricky' Header', QueryParam' endpoints to ComprehensiveAPI
- servant-docs: Quick'n'dirty implementation. Don't use modifiers information (yet).
For uniformity of Enter.
Previously, `ServerT Raw m ~ Application`. Seems reasonable, but has the
unfortunate consequence of making `Enter` useless for `Raw` routes.
With this change `Tagged m Application` is retagged by `Enter`.
