Hi guys,
I've had a discussion with Roy about GWT vs. Java plans, he asked me to share this information, so here we go.
GWT 2.6 ======= - patch pending merge: http://gerrit.ovirt.org/#/c/32135/ - support for Java 7 language syntax like <> operator etc. - once patch ^^ is merged, we can consolidate Java language compliance for whole Engine -> both frontend and backend can use Java 7 (yey!)
Good news - @amureini prepare the nose of the Animal Sniffer :) @Vojtech keep us posted so we'll bump the language version of common Curious to know, does GWT have a WebSockets module for 2 way communication with the backend and are we planning to use it?
GWT 2.7 ======= - planned support for *only* Java 8 language syntax like lambdas etc. but *without* emulating new Java 8 APIs like streams etc. (Java 8 API emulation should come in GWT 3.0)
Likely, GWT 2.7 will remove GWT deRPC implementation on which we currently rely on. (@Martin, can you please share details?)
This means that until we move UI to REST API, we can't upgrade post GWT 2.6, so this will put more pressure to work on oVirtJS project in consequence.
GWT 3.0 ======= - ETA early next year? - planned to fully support Java 8 -> both language and APIs - one of key highlights is better integration with JavaScript, which fits the scenario where GWT "application" is one module that's part of bigger application (hybrid approach) Thanks for sharing with us! Can you please elabroate more on this hybrid approach? With "hybrid approach" I meant a situation where the web application consists of distinct modules, each module providing some functionality.
The common base technology for all modules, as well as for the module infra itself, is JavaScript. Each module can export APIs that other modules can consume. The whole complexity of web application is broken by dividing its logical parts into modules. Each module can be built (and packaged too) as a separate project.
For a long time, I felt that GWT lived in its "own" world, with vast majority of GWT use cases = GWT to implement the whole web application.
GWT 3.0 should provide better JavaScript integration, so GWT can also more easily fill the role of a "module" as opposed to the traditional role of "the whole application".
Does this mean you're thinking of replacing some of the frontend parts with plain javascript and html and make them play with the GWT modules?
Cheers, Yair
