Re: [lyo-dev] [LYO] LyoDesigner for Jersey2.0

Hello everyone,

CCing you on the Lyo Designer discussion. The question is how much should LyoD support old Lyo releases.

Jim, Jad, I believe Alt1 and "Alt3" are the same thing. The users of Lyo 4.0 will use LyoD 4.0 and those who wish to stay on Lyo 2.4 use LyoD 2.4. Just as the users of Lyo 2.3 use LyoD 2.3.

Hi Jim

 

I am not sure what you mean by this third option.

 

The generated code will certainly look different for Wink or Jax-rs2.0.

I am inclined for Alt1, which means LyoDesigner 2.4.0 is suitable for OSLC4J 2.4.0, while LyoDesigner 4.0.0 is suitable for OSLC4J 4.0.0.

 

@Andrii! I am not sure why I only emailed committers. I think I just copied the email list from your latest email.

 

regards

There's a third option - sync Lyo designer 2.4.0 with OSLC4J 2.4.0 and leave it at that. 

Its not clear why any user of Lyo Designer would care about JAX-RS 1/2, as that's simply an internal REST services API. Nor do I see why they'd care what version of OSLC4J is used in the implementation. There code that depends on these versions is implementation detail. What they would care about is the features and functions of the server.

+1 for Alt1! 

Most importantly, I don't think anybody is using LyoD in production just yet and you still can get away with a breaking change or two. I don't have time to maintain Alt2 or anything related to that. Plus, there are security vulnerabilities in old releases that nobody should be using anyway.

P.S. Why not on lyo-dev?

Hi,

 

Now that Lyo 4.0 has moved to Jax-rs2.0, we need to update LyoDesigner generation to match. I see 2 alternatives that I would like your input on.

 

Alt1. Generate code that suits jax-rs2.0, making LyoDesigner 4.0 not suitable for people still using Lyo 2.4.0 (ie. Wink)

 

Alt2. Give the user an alternative to choose generation for Wink or Jax-rs2.0.

 

Of course, Alt1 is much easier for me to handle. But there is a risk that we loose those that still want to use Lyo 2.4.0.

Or, could it be that Jax-rs2.0 code is still compatible with Wink?

 

Regards

Jad

Ps. I’m now back online, and in the process of going through Lyo mails
