Revision as of 16:36, 15 October 2012 by Dedeugd.us.ibm.com (Talk | contribs) (add sample/examples for JavaSciprt and Webscokers support to Open Task list)

Open Task list

  • list of open Paho bugs
  • Binary releases of C and Java clients for download
  • LuaRock release of Lua client for download
  • Tutorials for C and Java clients
  • How to build and use C client on iOS
  • Test suite
  • Protocol compliance suite for reference implementations
  • Raise MQTT Lua client to the same functional level as the C and Java client
  • Update MQTT specification with mqtt.org / mailing list clarifications
  • Some idea of potential code additions are on the page discussing the Repository structure.
  • Sample/examples in the Eclipse M2M Sandbox for the JavaScript and Web Sockets support (when delivered).


The Paho project will target the Eclipse Kepler release (June 26th, 2013) with a 0.9 release under Incubator status, and two intermediate releases in 4Q12 and 1Q13.

0.1 Build (4Q12) "M0"

This will be a “snapshot” build of the

  • Lua, C, and Java MQTT clients,
  • Eclipse client view,
  • Any additional example code.

The 0.1 release will be as an “update site” with the primary goal to learn and exercise the Eclipse Build/Release process and tools including Tycho

0.x Release (1Q13) "M1"

  • Line items (common to all clients)
    • Consistent samples/examples for all language clients
    • Consistent documentation
  • C client line items
  • Eclipse client view line items
  • Java client line items
    • Make jar of paho client available for download (2012)
    • Set Java client to build automatically and make jar and doc available.
    • jar available via Mavern
    • Add a non blocking API making it simpler to create applications for mobile platforms such as Android
    • Rework logging trace to use best practise tools (like java.util.logging)
    • Support for Java Micro Edition
  • MQTT JavaScript client
    • Add a MQTT JavaScript client to Paho
    • Use WebSockets to enable 1st class MQTT support from web applications running in web browsers
  • Lua client line items
    • Implement QoS, clean session bit, username/password, make sure message header fully implemented (send and receive), support message identifier, SUBACK messages should check QoS level, deal with outstanding SUBACK messages, review "last activity in / out" timers, check for PINGRESP, better "wait for CONACK" handling, handle failed subscriptions, better error / retry handling, review Lua best practices for socket I/O and error handling
  • MQTT Protocol conformance tests
    • Reference implementation test bed (wire capture?)
    • Tracing tools/integration
  • Mobile platform support
  • Sample and Example Code (integrated in IDE where possible)
    • MqGnatt
    • REST APIs with end to end examples
    • Basic MQTT exerciser (Eurotech)
    • Wizards?
    • New examples tbs
    • websockets

0.9 Release (2Q13)
