[gwt-contrib] What is the porpouse of ReboundTypeRecorder?

[Andrés Testi]

I just found this class in the master but I can't find references to it. 
Where is ReboundTypeRecorder intended to be used?
Thanks.

[Andrés Testi]

Thanks for the clarification, John. Does this mean that 
UnifyAst.UnifyVisitor.handleGwtCreate() will be deprecated/removed? I'm 
afraid because I'm working on a prototype with heavy changes on 
handleGwtCreate().

Re: [gwt-contrib] What is the porpouse of ReboundTypeRecorder?

[John Stalcup]

Mmmm, yes and no.

as you know GWT.create() rebinding right now in our monolithic build pass
is statically calculated at compile time.

i'm working on adding a separate build pass and this pass requires that
GWT.create() handling be done dynamically at runtime.

the monolithic pass has smaller output and longer compile time and is best
for production releases.
the separate pass has larger output and shorter compile time and is best
for developer productivity.

so monolithic compilation and it's compile time GWT.create() rebinding will
never completely go away since it is key to smallest possible output size.

that being said, any extension of GWT.create() functionality that can't
also be implemented at runtime for the separate compilation pass, will not
be approved, at least not by me.

Re: [gwt-contrib] What is the porpouse of ReboundTypeRecorder?

[John Stalcup]

since we're both making changes to the rebinding system, there's a very
good chance that our changes are going to collide.

i'm in the process of breaking my separate compilation prototype into small
pieces (generally 200-500 lines), cleaning them up, testing them, getting
them reviewed, and then committed. i've got about 5500 lines remaining to
run through this process.

it sounds like you have a lot of outstanding changes as well. maybe yours
and my changes will merge best if you do the same thing (iteratively commit
in lots of small chunks).

Re: [gwt-contrib] What is the porpouse of ReboundTypeRecorder?

[Andrés Testi]

What I'm doing is a prototype for GWT.create() enhancement originally 
proposed by Ray Cronwell, and discussed in this group a few months ago. My 
prototype is near to be ready (next weekend I hope). I'm trying to keep it 
in sync with master, but if I detect that master has changes I can't 
handle, I will stop the merges. My intention is to have a working prototype 
to discuss possible improvements. 
My proposal is only syntactic sugar on GWT.create(), mainly source 
transformation. I don't think separated compilation will be an issue.
Thanks.

[gwt-contrib] Next GWT Contributor Hangout

[Bhaskar Janakiraman]

The next GWT contributors hangout will be on Wednesday, Oct 30, 10.45 - 
11.30am PST. 

We are making a change to the hangout sessions: it will be a regular 
hangout and not a hangout-on-air, but we will record the session and upload 
the video. Reasons for this:
1. Improved audio quality with regular hangout.
2. In the last couple of sessions, we only had 2-3 people who were watching 
it live. 

The video will be accessible from the GWT G+ 
page
.

As before, if you want to participate in person in the hangout, please send 
me your email address (to: bjanakiraman at google.com)  and I will invite 
you to the hangout (limit of 10 remote participants). 
Agenda:

- GWT 2.6, status, patches in progress
- Update on modular compilation and other on-going efforts. 

Thanks,
Bhaskar
