This has involved changing SseHandler to always return a SseConsumer even if it doesn't match - in the case of a non-match, the socket is closed immediately.
http4k-* : Upgrade some dependency versions.
http4k-core : Repackaging of non-core classes for SSE/WebSockets into new http4k-realtime-core module. No action required unless these classes are needed without an implementation.

http4k-testing-webdriver : [Breaking] Upgrade of APIs to match new v4 Selenium APIs. It is quite safe to continue to use previous versions of the http4k-testing-webdriver JAR if you are unable to upgrade immediately. The API is reasonably the same, but some of the imports have changed. The main one is that instead of importing org.openqa.selenium.By you should import org.http4k.webdriver.By, which is the new custom implementation.
http4k-core : Replace hostDemux() with reverseProxy().

v3.285.2¶

http4k-testing-servirtium : Fixed #553 - Servirtium storage fix for multi-line bodies.

http4k-* : Upgrade some dependency versions.
http4k-core [Small break]: Rework of ParameterMatch to consolidate with RouterMatch as they are kind of the same thing. ParameterMatch methods are now floating extensions instead, so just import them.

http4k-security-oauth : Adding AuthRequestWithRequestAuthRequestExtractor that will extract the request from the jwt, assuming the validator is implemented which can be used instead of just using AuthRequestFromQueryParameters if support for parsing a request jwt is required. H/T @tom

v3.221.0¶

http4k-*, Unlikely break from Java only : Make all custom http4k exceptions extend RuntimeException. This helps with Java compatibility so things like LensFailure inside Java Lambdas don't require catching (as they are caught/dealt with by other bits of http4k automatically)

v3.220.0¶

v3.199.0¶

http4k-format-jackson, Breaking : Fix #313 - ConfigurableJackson.autoBody implementation would not work with collections of polymorphic types. This fix has the effect of blowing up auto-json behaviour when classes are defined inside functions (causing nasty java.lang.reflect.GenericSignatureFormatError: Signature Parse error exceptions). To remedy, just move inlined classes outside of the functions that they are defined in. H/T @alphaho for the PR.
http4k-* : Update some dependency versions

v3.198.0¶

v3.178.0¶

http4k-security-oauth, Possibly breaking : Request is passed as a parameter to the ClientValidator. Just pass it in! :) H/T @tom
http4k-contract, Behaviour change : When specified, individual route security now replaces global security (this is as the security model in the OpenApi spec is specified) as opposed to both being applied.

v3.171.0¶

http4k-core, Break (mitigation) : Replaced default resource loader location for singlePageApp() to /public instead of root - this is for safety of NOT serving the root of the classpath by default.

v3.170.0¶

http4k-core : Add a warning when static() is used with no package path, thus exposing the contents of the classpath remotely.

v3.169.0¶

http4k-* : Update various dependencies.

v3.168.0¶

http4k-contract : Collect LensFailure causes into a single place when validating.

v3.167.0¶

http4k-contract, Possibly Break : Open out ErrorResponseRenderer interface to take LensFailure instead of the individual failures when rendering badResponse(). To fix, simply wrap the list of failures into a LensFailure.

v3.166.1¶

http4k-core : Tweak singlePageApp() routing handler, to correctly apply filters when fallback page is used.

v3.166.0¶

http4k-core : Added singlePageApp() routing handler, which matches both static content or falls back to the root path index file

v3.165.0¶

http4k-contract : Fix invalid OpenApi2 when root and base path match. H/T @rgladwell

http4k-server-undertow : Fix #260 - cannot set multiple response headers with same name

v3.158.0¶

http4k-contract : POSSIBLE BEHAVIOUR CHANGE DUE TO BUG: Fix #259 - Contract blocks do not produce 400s if an external CatchAll is provided. This may have an effect on how errors are generated (a 400 is produced instead of the previous 500 from the CatchAll).

v3.157.1¶

http4k-security-oauth : Fix broken deprecation annotation.

v3.157.0¶

http4k-security-oauth : Default to JSON format response in Access Token response
http4k-security-oauth : Renamed a couple of classes (AccessTokenContainer -> AccessToken), and removed isValid method from AuthorizationCodes because it doesn't make sense for this to be on the OAuthServer.

http4k-contract : Fix #228 - Support Map-based fields in OpenApi 3 Auto-schema generation as additionalProperties. H/T @noahbetzen-wk for the idea.

v3.145.0¶

http4k-contract : Reimplement Auto-schema generation using reflection. Added test cases to use the OpenApi generator to create valid code-based OpenApi clients using the OpenApi generator.

http4k-* : Update various dependencies.

v3.142.0¶

http4k-contract : Both OpenApi v2 and v3 are now supported, including automatic schema generation. Some classes for OpenApi2 have moved to a new package - Deprecations should provide most alternatives. See module docs for details. For OpenApi v3, optionally include http4k-format-jackson to get JSON schema models based on JVM objects.
http4k-format-jackson : Added reflective JSON schema creator, to be used for generating named models from JVM objects.

v3.141.0¶

http4k-core : - Fix #233 - MemoryBody blows up with "java.nio.ReadOnlyBufferException"
http4k-core : - Tighten up security on Basic and Bearer auth server filters. H/T @andymoody

v3.140.0¶

http4k-* : Update dependencies (including Kotlin bump to 1.3.31)
http4k-security-oauth : Handle user rejecting/failing authentication. H/T @andymoody

v3.139.0¶

http4k-security-oauth : Allow access token generation to explicitly reject an authorization code already used. H/T @andymoody

v3.138.1¶

http4k-security-oauth : Amend error responses from access token generation. H/T @andymoody

v3.138.0¶

http4k-contracts : Tweaks to Security model for http4k-contracts. (Renamed) ApiKeySecurity is now a proper class, and added BasicAuthSecurity. You can now also override the security model on a per-route basis.
http4k-contract : Added ability to set the Security on each individual contract route. This overrides any Security set on a contract-level basis.

v3.137.1¶

http4k-serverless : Allow invocation of serverless functions locally. H/T @Charlyzzz
http4k-core : Fix #226 - ResourceLoadingHandler not close stream

v3.137.0¶

http4k-security-oauth : Rename AuthRequestPersistence to AuthRequestTracking

v3.136.0¶

http4k-security-oauth : Allow the http request to be referenced when generating OAuth authorization codes. H/T @andymoody

v3.135.0¶

http4k-core : Change mime.types location so it doesn't conflic with other libraries. H/T @benusher and @dgliosca
http4k-testing-chaos : Added SnipRequestBody behaviour.
http4k-core : (Small) Breaking Fixed location of some extension files to be relevant to the particular package that they are referencing. This will require reimporting the new location into your source if you were using the imports.

v3.134.0¶

http4k-testing-approval : Made content-type aware approval tests check the content type after the content. This is friendlier for failing tests, as it is more important that the content is correct than the content-type (and often errors don't have content type set so you get an erroneous error message which masks the fact that the content was wrong).

v3.133.0¶

http4k-cloudnative : HandleUpstreamRequestFailed client filter now takes a predicate (Response) -> Boolean instead of a boolean. This allows for more fine grained custom control of which Responses are acceptable.
http4k-* : Upgrade deps, including Kotlin to 1.3.30.
http4k-contract : Fix #221 - Contract path fixed segments cannot contain slash characters.

v3.132.0¶

http4k-format-jackson : Convert Jackson to use readValue instead of convertValue. This fixes some problems with type conversions.

v3.131.0¶

http4k-core : (Possible) Break: Made lense implementations Query, Header etc clear previous values by default instead of appending. This leads to a more consistent behaviour. In order to be able to set multiple values on an object using a lense, use the multi form instead - eg. Header.required("foo") -> Header.multi.required("foo"). We envisage the impact of this change is limited as it's only Queries that generally can have multiple possible values, and in the vast majority of cases a replace rather than append is expected.

v3.130.0¶

http4k-contract : Generify contract handling code to allow for custom HttpMessageMeta<XYZ>

v3.129.0¶

(Slight) Break: Collapsed UpstreamRequestFailed exceptions to contain the status, and thus removing non-special cases like BadRequest and BadGateway. This makes them much easier to use in practice as users have access to the the status. To migrate, simply replace previous classes with UpstreamRequestFailed(Status.XYZ, message).
http4k-contract : Open up ContractRoute API to facilitate extension when defining a custom ContractRenderer.
http4k-* : Upgrade deps.

v3.128.0¶

http4k-core : Added base64 to the supported mappings for Query/Headers etc...
http4k-testing-approval : Approver does not write actual output if there is none to write and there is no approved content

v3.127.0¶

http4k-testing-approval : Improved Approver interface to more closely match the traditional assert<XYZ> approach - this results in a more discoverable/obvious API.
http4k-testing-hamkrest : Added ability to create a Hamkrest matcher directly from the Approver instance to be combined with other relevant matchers.

v3.126.0¶

http4k-testing-approval : Add support for XML and HTML approval tests.

v3.125.0¶

Added http4k-testing-approval module, which is compatible with JUnit5 tests and integrates with the OkeyDoke approval testing files and IntelliJ plugin. H/T to @jshiell for the inspiration Gist containing the base Junit5 Extension.

v3.124.0¶

http4k-security-oauth : Make authentication response available when creating AuthorizationCode.

v3.123.0¶

http4k-security-oauth : Introduce OAuthServer to http4k-security-oauth to assist in the creation of authorization servers.

v3.122.0¶

Generified GenerateXmlDataClasses filter, and added default implementations for http4k-format-jackson-xml and http4k-format-xml modules.
(Rename) Break: GenerateXmlDataClasses filter in http4k-format-xml is now GsonGenerateXmlDataClasses
Removed superfluous CatchLensFailure filter from http4k-contracts module. This is not required as lens failures are already handled by the main contract handler.

v3.121.0¶

Moved Jackson XML support to new module http4k-format-jackson-xml. Note that this is for auto-marshalling of data-classes only and does not expose an XML DOM model.

v3.120.0¶

Deprecated Body.view() lens construction in favour of a Body.viewModel() call which removes the implicitly called toLens(). This allows further mapping from one ViewModel type to another, and brings the view lens construction into line with the rest of the extension functions on Body.
Add auto-marshalling XML support to http4k-format-jackson module.
Upgrade deps.

v3.119.0¶

Add UpstreamRequestFailed exceptions and HandleUpstreamRequestFailed filters to http4k-cloudnative. These allow apps to neatly deal with upstream failure in a sensible way.

v3.118.0¶

Tweak contract() DSL to add remaining options for configuration.

v3.117.0¶

Renamed ChaosControls (deprecated) to ChaosEngine.

v3.116.0¶

Added new templating module http4k-templates-freemarker. H/T @amcghie for the PR implementing this
http4k-contract has a new DSL for construction of the contract which replaces the old one (now deprecated). This is consistent with the meta DSL used to construct individual contract routes and avoids repetition of the old API. We attempted to implement the standard replace-with deprecation, but IntelliJ didn't like it (too complex maybe), so we've hard coded the warning instead which code which should work.
Added PreFlightExtraction to contract module, which adds the ability to disable body-checking for contract routes. This will allow refining of routes or entire contracts to be more efficient.
Upgrade deps.

v3.115.1¶

Fix #217 - Cannot override the definitionId of a top-level array in OpenAPI
Upgrade deps

v3.115.0¶

Chaos now do not blat x-uri-template when used with a RoutingHttpHandler
Simplified usage of Once chaos trigger.
(Slight break) Consistentified (!) construction of Chaos Behaviours, Stages and Triggers. Replaced singletons with function calls. Eg. Always -> Always()

v3.114.0¶

(Possible Break): Fix #215 - LensFailure does not always include target object. Only change to the API is that IN generic in Lenses is now bounded by IN : Any. This fix is a actually internally consistent as we could not always include the target otherwise (which is an Any?).
Trim leading and trailing whitespace from extracted EnvironmentKey values.
Secret value is now only usable once via the use() function.
Upgrade to various deps.
Removed deprecations.

v3.113.0¶

Added some common types for Environmental setup, and equivalent BiDiLens mappings
Handle null response in Java Http client. H/T @FredNordin

v3.112.2¶

Fix #212 - allow null values in HTTP contract definitions. This does mean we lose the type definition for that field, but we don't blow up silently (which was the previous behaviour). H/T @xhanin

v3.112.1¶

Re-add Path.nonEmptyString() which was accidentally removed.

v3.112.0¶

Add support for prohibiting String unmarshalling in JSON auto-marshalling configuration.
HTTP Contracts now use the underlying ContractRenderer to produce the BadRequest and NotFound responses. Made OpenAPI open so that these responses can be customised.

v3.111.0¶

Add support for JSON views in Jackson module. H/T @xhanin for the donkey work.

v3.110.0¶

Breaking: slight rearrangement of RouteMeta receiving/returning methods to provide consistency when defining route contracts.

v3.109.0¶

Moved the set of predefined String BiDiMapping instances to their own class. Bulked out the auto-mapping configuration options.

v3.108.0¶

Upgrade to various deps.
Extracted out new BiDiMapping type, which encapsulates string <-> type conversions and removes a boatload of duplications. These conversions are now used consistently across all the various places (Lenses, auto-mapping).
Improved configurability of AutoMarshallingJson instances.

v3.107.0¶

Upgrade to various deps.
Fix #208 - Xml auto deserialisation incorrectly converting strings to numbers

v3.106.1¶

Fix #207 - repeating prefixes in static routes are not handled correctly. H/T @ruXlab for the PR to fix.

v3.106.0¶

Add http4k-server-ktorcio server backend. Note that whilst this module does allow http4k apps to plug into the Ktor-CIO engine, it does not provide fully front-to-back coroutine support.

v3.105.0¶

Preventing FallbackCacheControl from duplicating existing headers. H/T @leandronunes85
Breaking: Make Body.length nullable instead of throwing exception when value is not available. H/T @zvozin

v3.104.0¶

Upgrade to various deps.
Add session token support to AWS filter, and "credentials provider" to allow for rotating AWS sessions. H/T @dhobbs.
Breaking: Moved WsClient from org.http4k.testing to org.http4k.websocket.

v3.103.2¶

"Fix" #198 - Breaking change made in http4k-contracts to clarify/deconfuse API. Hid body parameter in contract route meta DSL - it is now receiving().
Upgraded some dependencies, including Gradle to v5.0.
Breaking: Resilience4j dependency upgrade causes a break when providing custom config. Simply insert the Config type generic to fix: e.g. RetryConfig.custom() -> RetryConfig.custom<RetryConfig>()

v3.102.1¶

Fix #197 - Swagger spec for form fields had incorrect description.

v3.102.0¶

Introduce interface for Environment

Enhancement of http4k-cloudnative - now supports extra-health check routes, and provide way to load app configuration via Properties files.

v3.98.0¶

Add filter allowing Gzipping based on an allowed set of content types. H/T @jshiell
Change HttpHandler extending HttpClients to use object invoke() mechanism, as the individual clients have no visible API surface of their own. Introduced DualSyncAsyncHttpHandler interface.

Webdriver checkbox handling improved. H/T @gypsydave5
upgrade to various versions

v3.96.0¶

upgrade to Kotlin 1.3.0

Fix checkbox behaviour in webdriver

~v3.39.4~ v3.93.4¶

Use Jetty latest release version (rather than RC one)

v3.39.3¶

Fix #189 - Uri toString now omits leading slash if the authority of a Uri is blank. This could be a potential break, but is actually more consistent as a Uri can currently be relative or absolute.

v3.39.2¶

Extend SetBaseUriFrom to support query parameters

v3.39.1¶

Added SetBaseUriFrom filter

v3.39.0¶

(Possible breaking change): Json is now only generified by a single type parameter instead of 2. For most usages, this type would have been identical anyway, but the upgrade of Argo has finally allowed the removal of this dead generic. Simply replace Json<Node, Node> with Json<Node>.
Added Offset datetime types to all JSON auto-marshalling libraries
Build logic for versioning is now in Kotlin. H/T @jmfayard for the PR

v3.35.2¶

Fix #167 - Reintroduce hasBody compatibility with common matchers such as containsString()
Remove deprecations.

v3.35.1¶

Fix #165 - AWS auth filter does not replace headers - it sets them (which breaks for request signing)
Fix #164 - Webdriver internal state breaks when navigating to a full URL
Fix #162 - SetHostFrom doesn't set 'Host' header correctly (missing port). H/T @elifarley

v3.35.0¶

Added some regex matchers to http4k-testing-hamkrest.
Added BearerAuth authentication Server and Client Filters - these work similarly to BasicAuth.

v3.34.0¶

Add default SamplingDecision param to ZipkinTraces - defaults to always sample.
Fix #150 - StaticRoutingHandler filters being called twice.
Fix #151 - POTENTIAL BREAK: Rework of Status objects to fix equality against the Status constant vals when a description has been overridden.

v3.33.2¶

Raise SO_BACKLOG in Apache and Netty server implementations.
Add PERMANENT_REDIRECT and UNPROCESSABLE_ENTITY Status object.

v3.33.1¶

No change from 3.33.0. Previous version couldn't be made available to maven central.

v3.32.0¶

Add support for propagation of the Zipkin x-b3-sampled header

v3.31.0¶

Changes to the Netty factory to enable running http4k on GraalVM. H/T @RichyHBM

Added etag parser filter. H/T @dgliosca for the PR
Fix #132 - Ensured that disableDefaultTyping is called in default Jackson implementation. This should be the default anyway, but has been added to ensure that we don't fall foul of CVE-2017-7525 and to surface awareness of this issue.

v3.27.0¶

OpenAPI now provides example values in the generated schema. H/T @skewwhiffy for the PR.

v3.26.6¶

Fix #126 - ResourceLoadingHandler can expose mapped resources into the root. <-- We think this is an important update, so please upgrade!

v3.26.5¶

Fix #125 - ApacheServer implementation now sets content length if present.

v3.26.4¶

Fix #123 - Multipart Body objects blow up when parsed after being debugged. As with all streams, care should be taken to not blow heap when internalising them for debugging purposes.

v3.26.3¶

Debugging filter now supports ignoring Multipart streams.

v3.26.2¶

Tweak: OpenAPI now doesn't return null values in the schema.

v3.26.1¶

Fix #124 - headers in WebSocket upgrade request are incorrectly joined.

v3.26.0¶

Removed supportedContentTypes field from OpenApi contract JSON, since this is a legacy field.

v3.25.0¶

Added option to Undertow to enable HTTP2 from main ServerConfig

v3.24.0¶

Upgrade various dependencies for Java 10 compatibility. H/T @tom
Fix bug with repeated params in Websocket upgrade request. H/T @tom

v3.23.1¶

Composite LensFailures now capture (at least) the first failing cause (probably the body parameter in the case of an http4k-contract module.

v3.23.0¶

Fix #116 - Can provide a custom Response creation method for CatchLensFailure. H/T @elifarley for the inspiration!

v3.22.4¶

Added singleton method for Json.array, since if you pass in a single JsonNode (Jackson), it accidentally iterates over the fields in the node instead of using the object as an entry in the array.
Fix #115 - Only add content-length for methods that allow content in AwsAuth filter

v3.22.3¶

Preserve routing information on request/response manipulation

v3.22.2¶

http4k-security-oauth module added - with support for OAuth2 Authorization Grant flow
Replaced classes reliant on javax.activation package, which allows Java 9+ to not require any external dependencies. \o/
Fix #112 - ApacheClient incorrectly sets headers on GET requests (this breaks F5 load balancers). H/T @simojenki
PR #110 - Websocket client timeouts are incorrectly translated as seconds instead of millis. HT @anorth
Core JavaHttpClient does not support streaming due to limitations with HttpURLConnection

v3.21.1¶

Fix #109 - Jackson treats integer values inconsistently, leading to matching errors when using hamkrest.

v3.21.0¶

Fix #107 - Killed the x-uri-template header and fixed the ReportHttpTransaction to have access to the routingGroup.
Altered ordering of filters in http4k-contract so that the route is identified before pre-filters and security are applied. This allows knowledge of the path to be accessible at the time of application of those filters.

v3.20.0¶

Introduce JavaHttpClient to http4k-core. It provides a very basic http client without any other 3rd party dependencies.

v3.19.0¶

PR #104 - Add optional time/date formatters to LensSpecs so you can choose you serialisation format. H/T @elifarley
Fix #105 - Swagger API json file: duplicate key in "definitions".

v3.18.1¶

Fixed PR #100 - URI template regex required extra escaping. This only affects Android deployments as IDE shows the regex escaping is redundant. H/T @privatwolke

v3.18.0¶

Breaking: converted contract pre-security filter to be a post-security filter. This means that all standard filters are applied before the security later, which allows for logging and monitoring and context setup. The previous filter mechanic applied security first, which didn't allow for this. In the unlikely event that post-security filters still need to be applied, use the withPostSecurityFilter() function when building the contract.
Docs for contract RouteMeta function parameters, and deprecated some unused functions (missed when we introduced the DSL).
PR #99 - Contract routes now support up to 10 path segments. Thanks to @scap1784 for the PR! :)

v3.17.1¶

Fix #97. Moshi does not fail when deserialise non-nullable fields correctly. Note that GSON still suffers from this problem

v3.17.0¶

Added a pre-security filter option to contract creation, so that you can explicitly specify behaviour to occur before security kicks in.

Convert Security (from sealed class) and ApiKey to be interfaces. This allows users to implement their own security models.

v3.15.0¶

Introduce HttpTransaction and new ReportHttpTransaction filter provide better generic API for reporting, along with the ability to label transactions for this purpose.
Breaking: Rework the metrics request counter and timer Filter API. There is now a HttpTransactionLabeller for you to add as many labels as required to the transaction. Each of these labels will be used to tag the metric.

v3.14.1¶

Fix #95 - Filters are now applied to "route not found" responses

v3.14.0¶

Fix #93 - Apache server doesn't like content-length or transfer-encoding headers present in http4k response.
Add ability to "name" input and output contract body definitions in an OpenAPI JSON doc. This applies to only the top level entity. If no override is passed, the objects are named according to their hashcode.

3.13.4¶

Fix #92 - cookie date should always use US locale

v3.13.3¶

Further tweak to Netty. H/T @FredDeschenes

Fix #84. OPTIONS requests are not detected by contract routes.
Added option to NOT authorise OPTIONS requests in ApiKey security filter.
Added support for Async HTTP clients and added new AsyncHttpClient interface, which is obviously used for HTTP clients only**, and not server-side calls. :)
New client module http4k-client-apache-async.
New metrics gathering module http4k-metrics-micrometer. Big H/T to @kirderf for the PR.
Added support for async to OkHttp client module.

v3.10.0¶

P/R 81 - adding headers and timeout to websocket client.

v3.9.0¶

Added compactify and prettify to Json implementations
Added Json.hasBody Hamkrest matchers for comparing bodies. Note these are extension methods and need to be referenced/imported as such.

v3.8.0¶

Added facility for non-blocking websocket client to react to onConnect event. This API is the same as the inbound, server-side API - ie. there are no explicit connection event handlers. H/T @tom for the idea.

v3.7.0¶

P/R #13 Create extension methods for Response to add caching headers. H/T @k0zakinio.

v3.6.1¶

Fix #78. Serialisation of raw lists using Moshi fails in the same way as the Jackson auto-conversions do. Added convenience methods to get around this.

v3.6.0¶

Added http4k-format-moshi to support the Square auto-marshalling library.

v3.5.1¶

v3.2.3¶

PR #70: Header order equality for Request/Response - H/T @gypsydave5.

v3.2.2¶

Switched out Status for WsStatus (with proper RFC code set) in Websockets.

v3.2.1¶

Typesafe Websockets! Jetty now supports websockets, using the same style of API in the main http4k routing.
(Possible) Breaking change: Because WsHandler (typealias) implements the same inbound interface as HttpHandler, you now cannot declare HttpHandlers without specifying the input type, so any "anonymous" handlers will not compile as a result. The required fix is very simple, but manual: `{ Response(OK) } should become { _:Request -> Response(OK) }

v3.1.3¶

Fix Request.form() for streaming requests

v3.1.2¶

Remove possibility of empty message for Path Lens failure.

v3.1.1¶

New (better!) API for http4k-contract module. Old meta DSL has been deprecated.

v3.0.1¶

Fix #63 - Apache Client Connect. timeout exception handling.

Upgrade various dependency versions.
Tidying of Multipart code.

v2.35.1¶

Fix #57. Static handlers behave oddly when combined with an HTTP verb in the routing tree.

v2.35.0¶

Fix #56. Altered behaviour of CatchLensFailure to NOT catch errors from unmarshalling Response objects. This was causing BAD_REQUEST to be incorrectly generated.
Simplification of generics around LensSpecs. This should not be a breaking change, (there were 3 generics, now the MID has been removed so there are just 2) but could break if signatures are used explicitly.

v2.34.0¶

Reordered generics in LensInjector to make sense. This should have no effect on most code-bases, but could break if signatures are used explicitly. Just flip the generic types to switch.

v2.33.1¶

Added support for unsigned AWS requests, which enables streaming content to S3.

v2.33.0¶

Added BodyMode.Request to configure streaming for clients.
ResponseBodyMode is now BodyMode.Response (Breaking change. Fixable with simple find/replace).

v2.32.0¶

Added ServerFilter.ProcessFiles filter to stream Multipart Files, convert them into references and replace inline in the Form.

v2.31.4¶

Avoid realising StreamBody unless necessary, which could break common usages of streaming.

v2.31.3¶

Tweaks to Server backends to improve efficiency.

v2.29.4¶

Refactor release.

Fix #50 - Webdriver does not normalise relative links correctly.

v2.29.2¶

Http client modules now catch and convert Socket Timeout exceptions to HTTP 504s (with a custom message)

v2.29.1¶

Tweaks to how recorded traffic is stored on disk. Thanks to @dkandalov for the PR around this.

v2.29.0¶

Added TrafficFilters for recording and replaying HTTP traffic. See org.http4k.traffic package for details.

Added facility to assign values into a RequestContext which is passed down the Filter chain.

v2.26.3¶

Fix #44 - Request cookies should not be wrapped in quotes.

v2.25.4¶

Fix #40 - GZip filters now use content-encoding headers instead of transfer-encoding.

v2.25.3¶

Fix #39 - ResponseBodyMode.Memory properly closes streams (breaks jetty + gzip).

v2.25.2¶

Ensure that streams are closed properly when consuming from an upstream client.

v2.25.1¶

Remove Apache client request streaming because it may not release connections properly.

v2.25.0¶

Add streaming support to HTTP Server and Client modules.
Remove CatchLensFailure ClientFilter as it will never be used.

v2.24.0¶

Added CatchLensFailure for ClientFilters - which catches un-deserializable invalid responses from clients and generates a BAD_GATEWAY error.

v2.23.4¶

Switch XML generation to Gson over Jackson because Jackson doesn't handle uppercase field names well.
Switch native XML parsed type to Document over Node.

v2.23.3¶

New algorithm for XML data class deserialisation, so un-deprecated XML methods.

v2.23.2¶

Deprecated methods in XML support due to limitation with underlying Jackson implementation.

Fixed bug with GenerateXmlDataClasses filter

v2.23.0¶

Renamed http4k-format-jackson-xml module to http4k-format-xml.

Fixed #30 - CachingClasspath template ResourceLoader not working with non-root packages.

v2.19.0¶

Fixed #29 - webdriver submission of text area.

Added support for newRequest() in new RouteBinder mechanic.

v2.18.0¶

Add support for unlimited nesting for routes() blocks. Removed the raw Route object, which can be replaced with Router or RoutingHttpHandler where appropriate.
As part of above, rejigged route setup logic. Deprecated old routing structure, so now "/path" to GET bind is "/path" bind GET to. To fix deprecation, simply switch the calls to "to" and "bind" in routing setup.
Rename of bind() in http4k-contract to be bindContract()

toString() implementations to aid debugging

v2.0.1¶

Readded missing default parameter for newRequest() on RouteSpec

v2.0.0¶

Breaking: Inversion of routing API. GET to "/someUri" is now "/someUri" to GET for consistency across the entire API.

Reimplementation of http4k-contract API to match main routing API. Contracts are now nestable.

v1.32.2¶

Fix Filters being applied twice in ContractRoutingHttpHandler

v1.32.1¶

More work on http4k-contract contract API
