Changelog

Changelog

This list is not currently intended to be all-encompassing - it will document major and breaking API changes with their rationale when appropriate:

v3.101.0

  • upgrades to dependencies
  • Improved Client-side HTTP status descriptions
  • Lenses now support Durations out of the box
  • Environments now support multi-value keys (comma separated)

v3.100.0

  • Make Undertow API more friendly
  • Fix to JsonReadinessCheckResultRenderer to actually implement the correct interface

v3.99.0

  • 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.

v3.97.0

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

v3.96.0

  • upgrade to Kotlin 1.3.0

v3.95.1

  • Tweak to K8S port variables.

v3.95.0

  • (Unlikely break): Change Http4kServer interface to return Unit from stop(). This affects all server implementations.
  • Added DSL function for working with JSON objects (scopes JSON as this). fun <T> Json<NODE>.invoke(Json<NODE>.() -> T)
  • New module http4k-cloudnative contains classes to help run http4k services inside cloud-native environments, including K8S.
  • Upgrade some dependencies
  • Deprecation: Moved Header.Common fields to main Header object. Extension properties should go there now.

v3.94.1

  • Use UTC when checking cookie expiry

v3.94.0

  • Deprecate String.toBody()
  • 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
  • Upgrade Kotlin, and various other dependencies

v3.38.1

  • Fix withChaosControls URL pattern so that it matches sub-routes ok on original handler

v3.38.0

  • Added BearerAuth and BasicAuth implementations which populate RequestContexts. Plus cookbook example :)

v3.37.1

  • Fix #177 - Make RequestContexts thread-safe.

v3.37.0

  • Upgrades to http4k-testing-webdriver. H/T @dickon for the PRs
  • Added ProxyHost request filter which is useful for writing proxy-type apps.

v3.36.1

  • Fix #168 - Fix rest of hamkrest matchers caused by generics mishap.
  • Upgrade HTTP client dependency versions.

v3.36.0

  • Added http4k-testing-chaos module, designed to enhance failure-mode testing for http4k apps. Massive H/T to @IgorPerikov for the PR which drove this module's creation.
  • Added http4k-incubator module, for hosting developing projects and other code which might be promoted to top-level modules in the future.

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.
  • Added option for defaulted() lenses to fall back to another supplied lens in the case of missing value. Thanks to @dmcg for the inspiration. :)

v3.34.3

  • Fix #160 - JavaHttpClient does not copy body stream correctly onto URL connection.

v3.34.2

  • Fix #159 - Contracts should not have Security applied to the description route by default.

v3.34.1

  • Fix #158 - Static and contract routes filters are applied in the wrong order.

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. This involves the following potential breaking change: The Status class is no longer a data class to tighten up encapsulation - user calls to copy() will have to be replaced.

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.

v3.33.0

  • Add convenient way to extract from as a Map from http message. H/T to @dmcg (this version is available in jcenter only)

v3.32.1

  • Fix #142 - Pebble templates don't load from JAR files.

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

v3.30.0

  • Allow all server implementations to start on port 0 (ie. find a free port) and then report it back as a part of the Http4kServer interface

v3.29.0

  • Make HTTP clients resilient to unknown host and connectionrefused exceptions
  • Implememted #134 - Added default (de)serialization for common JDK primitives to all Auto-marshalling JSON modules - eg. datetimes and UUIDs

v3.28.0

  • Fix #131 - Uri's created with paths that don't contain leading slashes.
  • 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.

v3.16.0

  • 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

v3.13.2

  • Fix #91 - large message handli ng in Netty

v3.13.1

  • Upgrade to Kotlin 1.2.20

v3.13.0

  • Support for operationId in OpenApi route metadata. H/T @danschultz for the PR.
  • Removed previously deprecated methods.

v3.12.0

  • New client module http4k-client-jetty, which supports both sync and async models.

v3.11.1

  • 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

  • Fix #76 - encoding of path segments to use URI encoding instead of URL form encoding.

v3.5.0

  • Added support for multiple HotReload template directories in HandlebarsTemplates. H/T @TomShacham
  • Fix #74 - Request tracing span/parentSpan set too early so was shared between outgoing requests.

v3.4.0

  • New server backend http4k-server-apache. H/T @kirderf for the PR :)
  • We now set the length of the incoming request body when it is available in the incoming request.

  • Handlebars now uses combination of Class and Template name to cache templates.

v3.3.0

  • Facility to compose TemplateRenderers with then() to provide fallback behaviour.

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.

v3.0.0

  • Added http4k-serverless-lambda module, allowing http4k applications to be deployed into AWS Lambda and then called from API Gateway. Effectively, the combination of these two services become just another Server back-end supported by the library. \o/

v2.38.1

  • RequestContextKey now follow the standardised Lens structure of required, optional, defaulted, and can now be removed (set to null). Replace calls to RequestContextKey.of() with RequestContextKey.required()

v2.36.0

  • Added a couple of useful ServerFilters.
  • 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.

v2.29.4

  • Refactor release.

v2.29.3

  • 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

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

v2.28.0

  • Added http4k-template-dust for Dust template engine support. Thanks to @npryce for the PR to add this.

v2.27.2

  • Fix #44 - Use quotes around cookie values

v2.27.1

v2.26.0

  • Added "catch all" routing option, which matches all methods to a handler.

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.

v2.21.1

  • Default body Content Negotiation strategy changed to None

v2.21.0

  • Converted Content-Negotiation strategy from an Enum to an interface, so that users can define their own strategies. We also now check encoding so there are 4-built in strategies to choose from: Strict, StrictNoDirective, NonStrict and None.

v2.20.1

  • Fixed #31 - Matching of segments in URIs is done after URLs are decoded, which results in not capturing encoded slashes in the path segments.

v2.20.0

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

v2.19.0

  • Fixed #29 - webdriver submission of text area.
  • Http clients now use a new instance of the default for each instantiation. Previously there was a shared instance.

v2.18.2

  • Fix AWS request signing for requests containing path with special characters

v2.18.1
