This ticket is a placeholder for describing the roadmap for Airframe 2019 releases.

• Milestone: Airframe 20 Milestone: Airframe 20 #839

Airframe 19

airframe-http

• Filter support airframe-http: Add HttpFilter #540
  • e.g., adding authentication filters before the router
• [ ] Add MultiMap for http request/response headers We usually don't use generic request/response for now
• Add http logging Add default http access log filter to airframe-http #399
• [ ] Add JMX metrics like TwitterServer -> airframe-http-finagle supports it
• Static content (e.g, html, CSS) provider airframe-http: Add StaticContent provider #843
• http server backend
  • finagle
  • akka-http
• Convenient factories to initialize servers.
  • The current implementation provides designs. Factory methods like HttpServer.newXXXServer(...) will be more useful. => Added FinagleServerFactory.newFinagleServer
• OpenAPI YAML/JSON generator
  • Add a very simple annotation for OpenAPI.
• [ ] gRPC support (idea) No urgency in our use cases
• giter8 template (@smdmts)

airframe-http-finagle

• Upgrade to Finagle 19.6.0 Client extension #531
• Admin server (Having an example Admin server would be good)
  • Configure JMX parameters (e.g., log level)
  • monitoring logs
  • monitoring stats
• [ ] Factory methods for building Finagle Requests (@takezoe) => FinagleRequestBuilder can be used

airframe-http-recorder

• http support HTTP support in http-recorder #527
• programmable http recorder. Programmable HTTP mock server #529
  • Recording pairs of http request/response without actual web services
• record/replay proxy airframe-http-recorder: Add createRecorderProxy #557
• Support the expiration of recorded responses http-recorder: Support expiration #559
• Custom http request matcher (headerExclude option seems sufficient for now)
• Custom http request handler

airframe-http-client

• Default http client bindings. It seems we have no strong need to support multiple http clients.
  • [ ] jetty-client
  • finagle http client
  • [ ] akka-http client
  • [ ] okhttp client
  • [ ] https://github.com/softwaremill/sttp
• Allow adding custom headers Client extension #531
• Client builder airframe-http-finagle: Add Finagle.client builder #760
• Generate client-side code from a server definition (e.g., sbt-plugin?)
• Minimize the client binding interface used for HttpException retry patterns
• JSON chuncked encoding support

airframe-di

• Design-time lifecycle hooks
• Show line numbers of bind[X] airframe-di: Show binding line numbers #530
  - [ ] Show dependency graph
  • Visualization with external tools (e.g., graphviz) will not solve issues that are happening at the source code level.
• [ ] Rename the module to airframe-di (keep the package name as wvlet.airframe) No urgency for this
• Rename airframe-macros to airframe-di-macros Rename airframe-macros to airframe-di-macros #560
• Integrating with famous Scala libraries
  • examples:
    • Using Airframe with Spark. We already have this example in production.
    • Using Airframe with JDBC drivers
    • Using Airframe with Play!
    • Using Airframe with Akka
    • Using Airframe for Dataflow
• In-class bind[X] support airframe-di: Support in-class bind[X] for classes with DISupport trait #816

airframe-surface

• Support Surface.objectFactory in Scala.js
• Support inner classes airframe-surface: Support inner classes #635

airframe-metrics

• Compute the most succinct TimeWindow from a time range airframe-metrics: Add TimeWindow.succinctWindowUnit #736
  • Calculate diff TimeWindow between start and end (@smdmts)

airframe-jmx

• [ ] Support JSON output for complex parameters -> Admin server can do a better job for HTTP server diagnosis
• Update doc on how to register JMXMBean
• [ ] Simplify the usage (e.g., just expose all public methods)

airframe-codec

• AnyCodec AnyCodec #536
• Strict mode for validating the presence of all parameters => added @required parameter airframe-codec: Add @required to mark must-have parameters #779
• MessageHolder -> CodecdContext
  • [ ] Custom error handling: Add a parsing context-based error handling. Using default values (zero) Added @required airframe-codec: Add @required to mark must-have parameters #779 annotation so that we can enforce having a value.
  • [ ] Custom parameter name normalization: snake_case, CamlCase input/output Using a safe default configuration is better.
• Scala.js support. See airframe-msgpack
• Optimize the pack/unpack performance when input/output types are known
• [ ] TimeWindow codec (e.g., retain the original duration strings) Relative time string (e.g., 1d) doesn't match with the absolute TimeWindow. Won't work on this.
• Use base64 encoding for binary -> string conversion (json, StringCodec) airframe-codec: string-binary format encoding #634
• Fix Option None -> null -> json: null handling Add an option to suppress null JSON param output #156

airframe-msgpack

• Scala.js support
  • Pure-Scala msgpack
  • Pure-Scala StreamPacker/Unpacker airframe-msgpack: Pure Scala packer/unpacker #789

• Nested cursor support for the better error handling
• Handle EOF without using EOFException

airframe-log

• [ ] Migrate to wvlet.airframe.log? no urgency for this
  • Retain wvlet.log.LogSupport

airframe-jdbc

• Add factory method for JDBC connection factory airframe-jdbc: Refine JDBC connection pool #858

airframe-config
